Abstract
Objectives: To investigate the clinical efficacy of unilateral biportal endoscopy (UBE) in the treatment of degenerative lumbar disease (DLD) and its impact on postoperative lumbar stability. Methods: This is a retrospective case series study. A total of 109 cases of DLD treated with UBE in the Department of Orthopaedic, Beijing Chaoyang Hospital Affiliated to Capital Medical University from July 2020 to June 2022 were analyzed retrospectively. There were 47 males and 62 females, aged (53.3±8.2) years (range: 21 to 80 years). The surgical segments were single segment in 80 cases, two segments in 25 cases, and three segments in 4 cases. The low back pain and leg pain of visual analogue scale (VAS), Japanese Orthopaedic Association (JOA) score and Oswestry disability index (ODI) were evaluated before and after operation. The modified MacNab criteria were used for evaluation of the clinical consequences. Postoperative three-dimensional lumbar CT was performed to observe the preservation of the facet joints and the angle of the medial surface of the facetectomy(β angle). At 12 months after surgery, X ray of the flexion and extension lumbar spine were reviewed. The comparison and analysis of the data were conducted using paired sample t tests or generalized estimation equations. Results: All 109 patients underwent operative procedures successfully. The operation time was (94.5±37.1) minutes (range:56 to 245 minutes), the times of X ray was 6.8±4.0 (range:4 to 16 times), and the days of hospitalization was (5.3±3.7) days (range:4 to 14 days). Complications included dural tears in 4 cases, transient lower limb numbness in 4 cases, epidural hematoma in 2 case. The follow-up time was (19.6±7.2) months (range:12 to 36 months). The postoperative low back pain VAS, leg pain VAS, JOA score and ODI were significantly improved(all P<0.05). According to the modified MacNab criteria, the excellent and good rate was 88.99%(97/109) at 12 months after surgery. One case underwent revision surgery because of recurrent lumbar disc herniation. In term of radiographic evaluation, the area of the surgical side facet joints after UBE surgery was reserved more than 60%. The β angle was less than 90° in all patients. After 12 months of surgery, there was no surgical segment instability or spondylolisthesis by the X-ray of the flexion and extension lumbar spine. Conclusion: UBE can achieve satisfactory clinical efficacy in the treatment of DLD, and maintain the stability of the lumbar spine.

Abstract
Milk proteins can be used as encapsulation walls to increase the bioavailability of active compounds because they can bind hydrophobic, hydrophilic, and charged compounds. The objective of this study was to investigate the effects of astaxanthin (ASTA) encapsulation and the functional properties of milk protein and ASTA nanocomposites by an ultrasound-assisted pH-shifting treatment of different milk proteins, including milk protein concentrate (MPC), micellar casein (MCC), and whey protein isolate (WPI). The ultrasound-assisted pH-shifting treatment of milk protein helped to improve the encapsulation rate of ASTA. Therein, MCC showed great improvement of encapsulating ASTA after co-treatment with the raised encapsulated rate of 5.11%, followed by WPI and MPC. Furthermore, the nanocomposites of ASTA with milk protein exhibit improved bioavailability, antioxidant capacity, and storage stability. By comparison, MCC-encapsulated ASTA has the best storage stability, followed by MPC, and WPI-encapsulated ASTA has the least stability over a 28-d storage period. The results of intrinsic fluorescence and surface hydrophobicity showed that milk protein underwent fluorescence quenching after binding to ASTA, which was due to the hydrophobic sites of the protein being occupied by ASTA. In general, the nanocomposites of milk protein and ASTA fabricated by using an ultrasound-assisted pH-shifting treatment have the potential to be better nano-delivery systems for ASTA in functional foods, especially MCC, which showed excellent performance in encapsulation after treatment technique.

Abstract
Objective: To examine whether the highest mediastinal lymph node (HMLN) metastasis had an influence on postoperative recurrence and survival among non-small cell lung cancer (NSCLC) patients with pN2 lymph node metastasis. Methods: A total of 261 patients who underwent radical resection of lung cancer and systematic lymph node dissection in the Department of Thoracic Surgery of Peking University First Hospital from January 2007 to December 2016 were retrospectively analyzed. There were 180 males and 81 females, aged (61.5±9.4) years (range: 31 to 83 years). There were 128 cases of HMLN-positive and 133 cases of HMLN-negative. They were pathologically confirmed N2 stage NSCLC and postoperative recurrence and survival were followed up. The Kaplan-Meier method was used to calculate disease-free survival (DFS) and overall survival (OS) curves according to whether HMLN metastasize or not. The Cox proportional hazards regression model was used for the prognostic analysis. Results: The median DFS and the median OS of the whole group were 28 months and 44 months, respectively. The median DFS in HMLN-positive and HMLN-negative patients was 19 months and 33 months, respectively (P=0.005). The median OS of HMLN-positive and HMLN-negative group was 37 months and 49 months, respectively (P=0.005). Multivariate analysis showed that pneumonectomy and visceral pleural invasion were independent risk factors for both postoperative OS (HR=1.85, 95%CI: 1.25 to 2.72, P=0.002; HR=1.82, 95%CI: 1.30 to 2.56, P=0.007) and DFS (HR=1.61, 95%CI: 1.10 to 2.35, P=0.014; HR=1.77, 95%CI: 1.27 to 2.46,P=0.001). HMLN metastasis and lymphovascular invasion were independent risk factors for only postoperative DFS (HR=1.39, 95%CI: 1.03 to 1.87, P=0.030; HR=1.40, 95%CI: 0.99 to 1.81, P=0.042). Conclusions: For patients of pN2 stage NSCLC, both postoperative recurrence and long-term survival were significantly worse in the HMLN metastatic group. In addition, pneumonectomy and visceral pleural invasion were unfavorable factors that affected both recurrence and overall survival. HMLN metastasis and lymphovascular invasion could shorten the postoperative time for DFS.

Abstract
Objective: To identify the antibiotic resistance, virulence genes, and sequence types of Pseudomonas aeruginosa (P. aeruginosa) strains isolated from blood. Methods: From November 2014 to December 2021, a total of 94 nonrepetitive P. aeruginosa isolates were obtained from blood samples of patients at the First Affiliated Hospital of Shandong First Medical University in Shandong Province, China. The bacteria were identified using matrix-assisted laser desorption ionization time of flight mass spectrometry. Antibiotic resistance of the P. aeruginosa isolates was detected using Vitek 2 Compact system. Polymerase chain reaction (PCR) was conducted for the 18 virulence genes, and multi locus sequence typing (MLST) was performed to identify the sequence types of the P. aeruginosa strains. The resistance rates and distributions of virulence genes between carbapenem resistant pseudomonas aeruginosa (CRPA) and carbapenem susceptible pseudomonas aeruginosa (CSPA) isolates were compared using the Chi-square test. Results: Among 94 P. aeruginosa isolates, 19 (20.2%) isolates were found to be multidrug resistant (MDR) bacteria, of which 17 were CRPA isolates and 2 were CSPA isolates. All strains contained more than 10 virulence genes. Except for exoU gene, the detection rate of other genes was above 83%. MLST analysis revealed a total of 66 different STs, including 59 existing STs and 7 novel STs. Among them, ST244 (n=11, 11.7%) and ST270 (n=7, 7.4%) were the dominant STs. Although these two types of isolates harbored the same virulence genes, the resistance rates to carbapenem were different. 54.5% (6/11) ST244 isolates were CRPA but all 7 ST270 isolates were CSPA. Conclusion: Although the resistance rates of P. aeruginosa strains isolated from blood were at a low level, some MDR and CRPA isolates were detected. As the high virulence gene detection rates and genetic diversity were found for P. aeruginosa strains isolated from blood, close attention should be paid to avoid transmission and outbreaks.

Abstract
Objective: To compare the differences in the prevalence of mild micro-hepatic encephalopathy (MHE) among patients with cirrhosis by using the psychometric hepatic encephalopathy score (PHES) and the Stroop smartphone application (Encephal App) test. Methods: This prospective, multi-center, real-world study was initiated by the National Clinical Medical Research Center for Infectious Diseases and the Portal Hypertension Alliance and registered with International ClinicalTrials.gov (NCT05140837). 354 cases of cirrhosis were enrolled in 19 hospitals across the country. PHES (including digital connection tests A and B, digital symbol tests, trajectory drawing tests, and serial management tests) and the Stroop test were conducted in all of them. PHES was differentiated using standard diagnostic criteria established by the two studies in China and South Korea. The Stroop test was evaluated based on the criteria of the research and development team. The impact of different diagnostic standards or methods on the incidence of MHE in patients with cirrhosis was analyzed. Data between groups were differentiated using the t-test, Mann-Whitney U test, and χ (2) test. A kappa test was used to compare the consistency between groups. Results: After PHES, the prevalence of MHE among 354 cases of cirrhosis was 78.53% and 15.25%, respectively, based on Chinese research standards and Korean research normal value standards. However, the prevalence of MHE was 56.78% based on the Stroop test, and the differences in pairwise comparisons among the three groups were statistically significant (kappa = -0.064, P < 0.001). Stratified analysis revealed that the MHE prevalence in three groups of patients with Child-Pugh classes A, B, and C was 74.14%, 83.33%, and 88.24%, respectively, according to the normal value standards of Chinese researchers, while the MHE prevalence rates in three groups of patients with Child-Pugh classes A, B, and C were 8.29%, 23.53%, and 38.24%, respectively, according to the normal value standards of Korean researchers. Furthermore, the prevalence rates of MHE in the three groups of patients with Child-Pugh grades A, B, and C were 52.68%, 58.82%, and 73.53%, respectively, according to the Stroop test standard. However, among the results of each diagnostic standard, the prevalence of MHE showed an increasing trend with an increasing Child-Pugh grade. Further comparison demonstrated that the scores obtained by the number connection test A and the number symbol test were consistent according to the normal value standards of the two studies in China and South Korea (Z = -0.982, -1.702; P = 0.326, 0.089), while the other three sub-tests had significant differences (P < 0.001). Conclusion: The prevalence rate of MHE in the cirrhotic population is high, but the prevalence of MHE obtained by using different diagnostic criteria or methods varies greatly. Therefore, in line with the current changes in demographics and disease spectrum, it is necessary to enroll a larger sample size of a healthy population as a control. Moreover, the establishment of more reliable diagnostic scoring criteria will serve as a basis for obtaining accurate MHE incidence and formulating diagnosis and treatment strategies in cirrhotic populations.

Abstract
Objectives: To understand the use of pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP) and related factors in men who have sex with men (MSM) in Shandong Province, and provide reference for the promotion of PrEP and PEP in MSM. Methods: From April to July in 2022, MSM were recruited from 7 sentinel surveillance sites in Shandong Province for a questionnaire survey, and the sample size of each city site was 400. The information about sociodemographic characteristics, sexual behaviors, the uses of PrEP and PEP and others were collected from the MSM, and blood samples were collected from them for HIV and syphilis testing. Results: A total of 2 815 MSM were investigated, the majority of them were aged less than 30 years (55.7%, 1 569/2 815), unmarried (68.6%, 1 931/2 815) and had education background of college and above (56.5%, 1 590/2 815). Only 9.2% (258/2 815) had used PrEP and 10.8% (305/2 815) had used PEP. Multivariate logistic regression showed that factors associated with high likelihood of PrEP use in MSM included age ≤30 years (aOR=4.04, 95%CI:1.25-13.01), self-perceived lower risk of HIV infection (aOR=1.76, 95%CI:1.16-2.68), group sex and commercial sex in the past six months (aOR=1.51, 95%CI: 1.10-2.09; aOR=1.69, 95%CI: 1.16-2.47), new-type drug use (aOR=1.53, 95%CI: 1.11-2.11), receiving peer education (aOR=1.56, 95%CI: 1.03-2.37), other people using PrEP (aOR=3.29, 95%CI: 2.48-4.36), and being HIV negative (aOR=8.40, 95%CI:1.12-63.12). Factor associated with low likelihood of PrEP use in MSM was anal sex with casual partner (aOR=0.67, 95%CI:0.49-0.90). Factors associated with high likelihood of PEP use in MSM included age under 50 years (≤30 years old: aOR=2.41, 95%CI:1.02-5.69; 31-49 years old: aOR=3.33, 95%CI:1.42-7.85), no self-perceived risk for HIV infection (aOR=1.87, 95%CI:1.12-3.11), group sex in the past six months (aOR=1.68, 95%CI:1.23-2.29), new-type drug use (aOR=3.86, 95%CI:2.94-5.07) and receiving no peer education (aOR=1.54, 95%CI:1.12-2.12). Conclusions: In Shandong, a higher proportion of MSM used PrEP and PEP. Peer education and self-perceived HIV infection risk education should be strengthened to increase the rates of PrEP and PEP use in MSM.

Abstract
ABSTRACT The efficacy of acupuncture in treating pain diseases has been recognized in clinical practice, and its mechanism of action has been a hot topic in academic acupuncture research. Previous basic research on acupuncture analgesia has focused mostly on the nervous system, with few studies addressing the immune system as a potential pathway of acupuncture analgesia. In this study, we investigated the effect of electroacupuncture (EA) on the β-endorphins (β-END) content, END-containing leukocyte type and number, sympathetic neurotransmitter norepinephrine (NE), and chemokine gene expression in inflamed tissues. To induce inflammatory pain, about 200 µL of complete Frester adjuvant (CFA) was injected into the unilateral medial femoral muscle of adult Wistar rats. Electroacupuncture treatment was performed for 3 days beginning on day 4 after CFA injection, with parameters of 2/100 Hz, 2 mA, and 30 minutes per treatment. The weight-bearing experiment and enzyme-linked immunosorbent assay showed that EA treatment significantly relieved spontaneous pain-like behaviors and increased the level of β-END in inflamed tissue. Injection of anti-END antibody in inflamed tissue blocked this analgesic effect. Flow cytometry and immunofluorescence staining revealed that the EA-induced increase in β-END was derived from opioid-containing ICAM-1 + /CD11b + immune cells in inflamed tissue. In addition, EA treatment increased the NE content and expression of β2 adrenergic receptor (ADR-β2) in inflammatory tissues and upregulated Cxcl1 and Cxcl6 gene expression levels. These findings provide new evidence for the peripheral analgesic effect of acupuncture treatment by recruiting β-END-containing ICAM-1 + /CD11b + immune cells and increasing the β-END content at the site of inflammation.

Abstract
Objectives: To investigate the potential classification of quality of life in HIV-infected men who have sex with men (HIV-infected MSM) and to analyze possible influencing factors of different categories. Methods: A questionnaire survey was conducted among HIV-infected MSM who received antiretroviral treatment (ART) in an infectious disease hospital in Ji'nan, Shandong Province from October to December 2020. The quality of life scores in six domains were analyzed by latent profile analysis (LPA), and possible related factors of potential classification were explored by ordinal logistic regression analysis. Results: A total of 584 HIV-infected MSM were included in this study. LPA divided their quality of life into three categories, named low score, medium score and high score groups, accounting for 34.4% (201/584), 49.8% (291/584), and 15.8% (92/584), respectively. Multivariate ordinal logistic regression analysis showed that age above 40 years (aOR=1.77, 95%CI:1.11-2.80), monthly average income of 3 000 Yuan and below (aOR=3.15, 95%CI:1.72-5.76), monthly average income of 3 001-5 000 Yuan (aOR=2.26, 95%CI:1.41-3.62), distance to the hospital to receive drugs farer than 40 kms (aOR=1.76, 95%CI:1.07-2.89), and adverse reactions after taking drugs (aOR=2.31, 95%CI:1.65-3.23) were factors associated with low level of quality of life. Conclusions: The qualities of life of HIV-infected MSM showed group heterogeneity and were at high levels. Attention should be focused on HIV-infected MSM who are at older age, with low income, and long distance to access the health facilities. The measures should be taken to reduce the adverse reactions of ART drugs and improve the quality of life.

Abstract
Objective: To analyze whole brain structural volume asymmetry in temporal lobe epilepsy with hippocampal sclerosis (TLE-HS) using automated brain segmentation technology, and to investigate the application value of this technology in the diagnosis of TLE-HS and the performance in determining the location the lateralization of epileptogenic focus. Methods: Twenty-eight patients with TLE-HS were enrolled in the First Affiliated Hospital of Zhengzhou University from April 2019 to October 2020, including 13 females and 15 males, aged ranged from 18 to 63 (30±12) years, and these patients were divided two group according to the epilepsy lateralization, left TLE-HS(LTLE-HS) group (n=11), right TLE-HS(RTLE-HS) group (n=17) and 28 normal controls [aged ranged from 18 to 49 (29±10) years]. All of these subjects underwent three-dimensional T1 weighted image (3D T1WI). The differences of brain structure and volumes in LTLE-HS, RTLE-HS and normal controls group were retrospectively analyzed, and Pearson's correlation coefficient was used to evaluate the left and right volume correlations, and effect size was used for evaluating the differences in left and right volume averages. The asymmetry index (AI) of the left and right lateral volumes in each group was also calculated and compared among the three groups. Results: Standard volumes of all structures within the brain were asymmetric in the normal controls, LTLE-HS, and RTLE-HS groups, with smaller volumes of ipsilateral hippocampus than contralateral hippocampus in both the LTLE-HS and RTLE-HS groups(0.20%±0.03% vs 0.24%±0.02%,0.21%±0.03% vs 0.25%±0.02% respectively;both P<0.001), and smaller volumes of gray and white matter of the ipsilateral temporal lobe than contralateral in the LTLE-HS group(4.41%±0.38% vs 5.01%±0.43%,1.83%±0.22 % vs 2.22%±0.14%;both P<0.001). There was a moderate to strong linear correlation (0.553<r<0. 964,all P<0.05) between left and right lateral volumes in the normal controls, LTLE-HS, and RTLE-HS groups. All three groups showed the largest effect sizes in the cingulate gyrus (The effect sizes were 3.07, 4.85 and 4.22 in control, LTLE-HS and RTLE-HS, respectively.). The AI values of the hippocampus, temporal lobe gray matter, and temporal lobe white matter were statistically different among the three groups (-1.48±8.64 vs 15.91±10.15 vs -17.59±10.00, 7.46±2.67 vs 12.67±6.67 vs 3.67±6.15, 6.53±3.71 vs 19.91±9.85 vs 1.57±8.38;all P<0.001). Conclusion: Volumetric measurements by automated brain segmentation techniques can play an important role in preoperative assessment of TLE, and the asymmetry of brain volume may be of value in determining the localization and extent of the epileptogenic focus.

Abstract
Plant disease resistance is a complex process that is maintained in an intricate balance with development. Increasing evidence indicates the importance of posttranscriptional regulation of plant defense by RNA binding proteins. In a genetic screen for suppressors of Arabidopsis (Arabidopsis thaliana) accelerated cell death 6-1 (acd6-1), a small constitutive defense mutant whose defense level is grossly in a reverse proportion to plant size, we identified an allele of the canonical flowering regulatory gene FLOWERING LOCUS K HOMOLOGY DOMAIN (FLK) encoding a putative protein with triple K homology (KH) repeats. The KH repeat is an ancient RNA binding motif found in proteins from diverse organisms. The relevance of KH-domain proteins in pathogen resistance is largely unexplored. In addition to late flowering, the flk mutants exhibited decreased resistance to the bacterial pathogen Pseudomonas syringae and increased resistance to the necrotrophic fungal pathogen Botrytis cinerea. We further found that the flk mutations compromised basal defense and defense signaling mediated by salicylic acid (SA). Mutant analysis revealed complex genetic interactions between FLK and several major SA pathway genes. RNA-seq data showed that FLK regulates expression abundance of some major defense- and development-related genes as well as alternative splicing of a number of genes. Among the genes affected by FLK is ACD6, whose transcripts had increased intron retentions influenced by the flk mutations. Thus, this study provides mechanistic support for flk suppression of acd6-1 and establishes that FLK is a multifunctional gene involved in regulating pathogen defense and development of plants.

Abstract
Lifespan longevity has attracted increasing attention with societal development. To counter the effects of aging on longevity, we focused on the natural chemicals of plants. In this study, we investigated the effects of puerarin supplementation on the lifespan of Drosophila melanogaster. Puerarin supplementation significantly extended the lifespan of D. melanogaster at 60 μM and 120 μM by upregulating proteasome subunit beta 5 (prosbeta5) and sirtuin-1 (Sirt1). However, puerarin-induced longevity of male flies (F0 generation) may not be passed on to descendants. Additionally, a puerarin diet for 10 and 25 days did not influence the body weight and food intake of male Canton-S flies. Puerarin significantly improved the climbing ability, starvation resistance, and oxidation resistance of male flies by upregulating the expression of Shaker, catalase (CAT), superoxide dismutase 1 (SOD1), and Methuselah, and downregulating poly [ADP-ribose] polymerase (PARP-1) and major heat shock 70 kDa protein Aa (HSP70). Moreover, 120 μM puerarin supplementation for 25 days significantly increased adenosine 5' triphosphate (ATP) content by increasing adenosine 5'-monophosphate (AMP)-activated protein kinase (AMPK) levels. Additionally, the puerarin diet for 25 days suppressed male fecundity in male flies by decreasing the levels of Bam and Punt. Mechanistically, puerarin enhanced lysosome-involved autophagy by promoting the expression of lysosome markers [β-galactosidase and lysosomal associated membrane protein 1 (LAMP1)], and elevating the levels of autophagy-related genes, including autophagy-associated gene 1 (ATG1), ATG5, and ATG8b. However, puerarin decreased the phosphorylation of the target of rapamycin (TOR) protein. In conclusion, puerarin is a promising compound for improving the longevity of D. melanogaster by activating autophagy.

Abstract
Objective The aim of this study was to explore the profile of cytokine changes during the combination therapy with pegylated interferon alpha (PEG-IFN-α) and its relationship with HBsAg loss in nucleos(t)ide analogs (NAs)-suppressed chronic hepatitis B patients. Methods Seventy-six patients with chronic hepatitis B with HBsAg less than 1,500 IU/ml and HBV DNA negative after receiving ≥ 1-year NAs therapy were enrolled. Eighteen patients continued to take NAs monotherapy (the NAs group), and 58 patients received combination therapy with NAs and PEG-IFN-α (the Add-on group). The levels of IFNG, IL1B, IL1RN, IL2, IL4, IL6, IL10, IL12A, IL17A, CCL2, CCL3, CCL5, CXCL8, CXCL10, TNF, and CSF2 in peripheral blood during treatment were detected. Results At week 48, 0.00% (0/18) in the NAs group and 25.86% (15/58) in the Add-on group achieved HBsAg loss. During 48 weeks of combined treatment, there was a transitory increase in the levels of ALT, IL1RN, IL2, and CCL2. Compared to the NAs group, CXCL8 and CXCL10 in the Add-on group remain higher after rising, yet CCL3 showed a continuously increasing trend. Mild and early increases in IL1B, CCL3, IL17A, IL2, IL4, IL6, and CXCL8 were associated with HBsAg loss or decrease >1 log, while sustained high levels of CCL5 and CXCL10 were associated with poor responses to Add-on therapy at week 48. Conclusions The serum cytokine change profile is closely related to the response to the combination therapy with PEG-IFN-α and NAs, and may help to reveal the mechanism of functional cure and discover new immunological predictors and new therapeutic targets.

Abstract
Introduction Recent research has focused on the local control of articular inflammation through neuronal stimulation to avoid the systemic side effects of conventional pharmacological therapies. Electroacupuncture (EA) has been proven to be useful for inflammation suppressing and pain reduction in knee osteoarthritis (KOA) patients, yet its mechanism remains unclear. Methods In the present study, the KOA model was established using the intra-articular injection of sodium monoiodoacetate (MIA) (1 mg/50 μL) into the knee cavity. EA was delivered at the ipsilateral ST36-GB34 acupoints. Hind paw weight-bearing and withdrawl thresholds were measured. On day 9, the histology, dep enrichment proteins, cytokines contents, immune cell population of the synovial membrane of the affected limbs were measured using HE staining, Masson staining, DIA quantitative proteomic analysis, flow cytometry, immunofluorescence staining, ELISA, and Western Blot. The ultrastructure of the saphenous nerve of the affected limb was observed using transmission electron microscopy on the 14th day after modeling. Results The result demonstrated that EA intervention during the midterm phase of the articular inflammation alleviated inflammatory pain behaviors and cartilage damage, but not during the early phase. Mid-term EA suppressed the levels of proinflammatory cytokines TNF-α, IL-1β, and IL-6 in the synovium on day 9 after MIA by elevating the level of sympathetic neurotransmitters Norepinephrine (NE) in the synovium but not systemic NE or systemic adrenaline. Selective blocking of the sympathetic function (6-OHDA) and β2-adrenergic receptor (ICI 118,551) prevented the anti-inflammatory effects of EA. EA-induced increment of the NE in the synovium inhibited the CXCL1-CXCR2 dependent overexpression of IL-6 in the synovial macrophages in a β2-adrenergic receptor (AR)-mediated manner. Discussion These results revealed that EA activated sympathetic noradrenergic signaling to control local inflammation in KOA rats and contributed to the development of novel therapeutic neurostimulation strategies for inflammatory diseases.

Abstract
OBJECTIVE To observe the effect of electroacupuncture (EA) on pain behavior, synovial inflammatory response and demyelination of saphenous nerve in the rats modeled with knee osteoarthritis (KOA) and explore the effect mechanism of EA for reliving allodynia. METHODS Eighty-four male SD rats were randomly divided into a control group, a model group and an EA group, 28 rats in each one. Intra-articular injection of sodium monoiodoacetate (MIA) was administered in right knee joint of each rat in the model group and the EA group to establish the KOA model. In the EA group, separately, on day 5, 7 and 9 after modeling, EA was applied at "Zusanli" (ST 36) and "Yanglingquan" (GB 34) on the right side, with disperse-dense wave (2 Hz/15 Hz), 1 mA in current intensity, for 30 min in one intervention, once a day, and 3 interventions were required. On the 9th day after modeling, the weight-bearing rate was calculated for the affected limbs of the rats in each group, the synovial morphological changes were observed using HE and Masson staining, flow cytometry was adopted to detect the synovial immunocyte counts, and MSD multi-spot assay was used to detected the synovial inflammatory cytokine content. On the 14th day after modeling, the hind-paw mechanical withdrawal threshold was observed in each group and the ultrastructure of the saphenous nerve was observed under transmission electron microscopy. RESULTS On the 9th day after modeling, compared with the control group, the weight-bearing rate of the affected limb was reduced (P<0.01), the synovial hyperplasia, inflammatory cell infiltration and synovial fibrosis occurred in the affected limb; the counts of synovial CD11b+ cells and M1 macrophages (CD11b+CD86+) were increased (P<0.01), the contents of tumor necrosis factor-α (TNF-α), interleukin (IL)-6, IL-1β, IL-10 and IL-13 in the synovial tissue were elevated (P<0.01, P<0.05) for the rats of the model group. Compared with the model group, the weight-bearing rate of the affected limb was increased (P<0.05), the synovial hyperplasia, inflammatory cell infiltration and synovial fibrosis were mitigated, the counts of CD11b+ cells and M1 macrophages (CD11b+CD86+) in the synovial tissue, and the contents of TNF-α and IL-6 were reduced (P<0.01, P<0.05) in the EA group. On the 14th day after modeling, the hind-paw mechanical withdrawal threshold was reduced in the model group when compared with the control group (P<0.01), and it was increased in the EA group when compared with the model group (P<0.05). Besides, in the model group, obviously, the myelin sheath structure was destroyed, the myelin layer was disintegrated and loosened, the axon was extruded or the layer thicken and cracked. Compared with the model group, the injury of saphenous nerve was alleviated remarkably in the EA group. CONCLUSION The intervention with EA may attenuate the synovial inflammatory response and the injury of saphenous nerve in the affected limb of the rat with KOA, so that the spontaneous pain during the synovial inflammatory response stage and allodynia at the later stage are relieved.

Abstract
OBJECTIVE To investigate the mechanism of electroacupuncture (EA) "Zusanli" (ST36) in delaying colon "inflammation-cancer transformation" in mice by anti-inflammatory. METHODS C57BL/6J mice were randomly divided into normal, model and EA groups, with 12 mice in each group. The mouse model of colorectal cancer (CRC) was established by intrape-ritoneal injection of azomethane (AOM) and feeding dextran sodium sulfate (DSS). At the beginning of the 2nd cycle, EA was applied to bilateral ST36 for 30 min once every other day for 12 times. The number of colon tumors in each group was observed, and the weight and length of colon were recorded. The contents of interleukin (IL)-1β, IL-6, IL-17A, IL-23, tumor necrosis factor (TNF)-α and CXC chemokine ligand 1 (CXCL1) of serum and colon tissue were detected by MSD multifactorial assay.The apoptosis of local cells in colon tumor was observed by TUNEL staining. Cell proliferation in colon tumor was observed by immunohistochemistry. RESULTS Compared with the normal group, the colon length was significantly shortened (P<0.05) and the colon mass was significantly increased (P<0.001) in the model group, the contents of IL-1β, IL-6, TNF-α, IL-17A and CXCL1 of serum and colon tissue were significantly increased (P<0.05, P<0.01, P<0.001), and the content of IL-23 was increased in colon tissue (P<0.05) in the model group. Compared with the model group, the colon mass was decreased (P<0.05) and the contents of IL-1β, IL-6, TNF-α and IL-17A in serum were decreased (P<0.05), while the contents of IL-17A, CXCL1 and IL-23 in colon tissue were decreased (P<0.05) in the EA group, the percentage of local apoptotic cells in the EA group was increased (P<0.001), the percentage of PCNA positive cells was decreased (P<0.001), the number of tumors and the tumor volume were significantly decreased (P<0.01, P<0.05). The contents of IL-6, TNF-α, IL-17A and IL-23 in serum of CRC mice were positively correlated with tumor burden (P<0.05).The contents of IL-1β, TNF-α, CXCL1 and IL-23 in colon tissue of CRC mice were positively correlated with tumor burden (P<0.05). CONCLUSION Electroacupuncture at ST36 can inhibit the inflammatory response of AOM/DSS inflammatory associated CRC mice and delay the "inflammation-cancer transformation" of colon.

Abstract
Background and aimsPrecise predictors are lacking for hepatitis B surface antigen (HBsAg) clearance under the combination therapy of nucleos(t)ide analogs (NA) and pegylated interferon-alpha (PEG-IFN-α) in patients with chronic hepatitis B (CHB). This study aimed to determine the quantitative anti-hepatitis B core antibody (qAnti-HBc) and quantitative hepatitis B core-related antigen (qHBcrAg) as predictors for HBsAg clearance in NA-suppressed patients with CHB receiving PEG-IFN-α add-on therapy.MethodsSeventy-four CHB patients who achieved HBV DNA suppression (HBV DNA < 20 IU/ml) and quantitative HBsAg (qHBsAg) < 1,500 IU/ml after ≥1 year of NA treatment were enrolled. Fifteen patients continued on NA monotherapy, while 59 patients received PEG-IFN-α add-on therapy. Serum qAnti-HBc and qHBcrAg levels were detected every 12 or 24 weeks for add-on and NA-alone groups, respectively.ResultsSerum qAnti-HBc but not qHBcrAg levels at baseline were negatively correlated with the duration of prior NA therapy. After 48-week treatment, both qAnti-HBc and qHBcrAg levels declined further, and 17/59 (28.81%) and 0/15 (0%) achieved HBsAg clearance in add-on and NA groups, respectively. In the add-on group, the rate of HBsAg clearance was significantly higher in patients with baseline qAnti-HBc < 0.1 IU/ml (52.63%). Logistic regression analysis identified baseline qAnti-HBc but not qHBcrAg, which was an independent predictor for HBsAg loss. Receiver operating characteristic curve analysis showed that the combination of qAnti-HBc and qHBsAg had a better predictive value for HBsAg clearance.ConclusionsA combination of qHBsAg and baseline qAnti-HBc levels may be a better prediction strategy for HBsAg clearance in NA-suppressed CHB patients receiving PEG-IFN-α add-on therapy.

Abstract
BACKGROUND Accurate and comprehensive annotation of transcript sequences is essential for transcript quantification and differential gene and transcript expression analysis. Single-molecule long-read sequencing technologies provide improved integrity of transcript structures including alternative splicing, and transcription start and polyadenylation sites. However, accuracy is significantly affected by sequencing errors, mRNA degradation, or incomplete cDNA synthesis. RESULTS We present a new and comprehensive Arabidopsis thaliana Reference Transcript Dataset 3 (AtRTD3). AtRTD3 contains over 169,000 transcripts-twice that of the best current Arabidopsis transcriptome and including over 1500 novel genes. Seventy-eight percent of transcripts are from Iso-seq with accurately defined splice junctions and transcription start and end sites. We develop novel methods to determine splice junctions and transcription start and end sites accurately. Mismatch profiles around splice junctions provide a powerful feature to distinguish correct splice junctions and remove false splice junctions. Stratified approaches identify high-confidence transcription start and end sites and remove fragmentary transcripts due to degradation. AtRTD3 is a major improvement over existing transcriptomes as demonstrated by analysis of an Arabidopsis cold response RNA-seq time-series. AtRTD3 provides higher resolution of transcript expression profiling and identifies cold-induced differential transcription start and polyadenylation site usage. CONCLUSIONS AtRTD3 is the most comprehensive Arabidopsis transcriptome currently. It improves the precision of differential gene and transcript expression, differential alternative splicing, and transcription start/end site usage analysis from RNA-seq data. The novel methods for identifying accurate splice junctions and transcription start/end sites are widely applicable and will improve single-molecule sequencing analysis from any species.

Abstract
Glioma stem cells (GSCs) are self-renewing tumor cells with multi-lineage differentiation potential and the capacity of construct glioblastoma (GBM) heterogenicity. Mitochondrial morphology is associated with the metabolic plasticity of GBM cells. Previous studies have revealed distinct mitochondrial morphologies and metabolic phenotypes between GSCs and non-stem tumor cells (NSTCs), whereas the molecules regulating mitochondrial dynamics in GBM cells are largely unknown. Herein, we report that carnitine palmitoyltransferase 1A (CPT1A) is preferentially expressed in NSTCs, and governs mitochondrial dynamics and GSC differentiation. Expressions of CPT1A and GSC marker CD133 were mutually exclusive in human GBMs. Overexpression of CPT1A inhibited GSC self-renewal but promoted mitochondrial fusion. In contrast, disruption of CPT1A in NSTCs promoted mitochondrial fission and reprogrammed NSTCs toward GSC feature. Mechanistically, CPT1A overexpression increased the phosphorylation of dynamin-related protein 1 at Ser-637 to promote mitochondrial fusion. In vivo, CPT1A overexpression decreased the percentage of GSCs, impaired GSC-derived xenograft growth and prolonged tumor-bearing mice survival. Our work identified CPT1A as a critical regulator of mitochondrial dynamics and GSC differentiation, indicating that CPT1A could be developed as a molecular target for GBM cell-differentiation strategy.

Abstract
Glioblastoma is a lethal primary brain tumor with abundant immune-suppressive glioblastoma-associated macrophage (GAM) infiltration. Skewing immune suppressive GAMs towards an immune-activating phenotype represents a promising immunotherapeutic strategy against glioblastoma. Herein, we reported that genetic deletion of miRNA-processing enzyme Dicer in macrophages inhibited the growth of GL261 murine glioblastoma xenografts and prolonged survival of tumor-bearing mice. Single cell RNA sequencing (scRNA-seq) of the tumor-infiltrating immune cells revealed that Dicer deletion in macrophages reduced the proportion of cell-cycling GAM cluster and reprogramed the remaining GAMs towards a proinflammatory activation state (enhanced phagocytotic and IFN-producing signature). Dicer-deficient GAMs showed reduced level of cyclin-dependent kinases (CDK1 and CDK2) and increased expression of CDK inhibitor p27 Kip1, thus manifesting impaired proliferation. Dicer knockout enhanced phagocytotic activity of GAMs to eliminate GL261 tumor cells. Increased proinflammatory GAM clusters in macrophage Dicer-deficient mice actively interacted with tumor-infiltrating T cells and NK cells through TNF paracrine signaling to create a pro-inflammatory immune microenvironment for tumor cell elimination. Our work identifies the role of Dicer deletion in macrophages in generating an immune-activating microenvironment, which could be further developed as a potential immunotherapeutic strategy against glioblastoma.

Abstract
Tumour-associated macrophages (TAMs) abundantly infiltrate high-grade gliomas and orchestrate immune response, but their diversity in isocitrate dehydrogenase (IDH)-differential grade-4 gliomas remains largely unknown. This study aimed to dissect the transcriptional states, spatial distribution and clinicopathological significance of distinct monocyte-derived TAM (Mo-TAM) and microglia-derived TAM (Mg-TAM) clusters across glioblastoma-IDH-wildtype and astrocytoma-IDH-mutant-grade 4 (Astro-IDH-mut-G4). Single-cell RNA sequencing was performed on four cases of human glioblastoma and three cases of Astro-IDH-mut-G4. Cell clustering, single-cell regulatory network inference and gene set enrichment analysis were performed to characterize the functional states of myeloid clusters. Spatial distribution of TAM subsets was determined in human glioma tissues using multiplex immunostaining. The prognostic value of different TAM-cluster specific geneset was evaluated in the TCGA glioma cohort. Profiling and unbiased clustering of 24,227 myeloid cells from glioblastoma and Astro-IDH-mut-G4 identified 9 myeloid cell clusters including monocyte, six Mo/Mg-TAM subsets, dendritic cell, and proliferative myeloid cluster. Different Mo/Mg-TAM clusters manifest functional and transcriptional diversity controlled by specific regulons. Multiplex immunostaining of subset-specific markers identified spatial enrichment of distinct TAM clusters at peri-vascular/necrotic areas in tumour parenchyma or at tumour-brain interface. Glioblastoma harboured a substantially higher number of monocytes and Mo-TAM-inflammatory cluster, whereas Astro-IDH-mut-G4 was with higher proportion of TAM subset mediating antigen presentation. Glioblastomas with higher proportion of monocytes exhibited a mesenchymal signature, increased angiogenesis and worse patient outcome. Our findings provide insight into myeloid cell diversity and its clinical relevance in IDH-differential grade-4 gliomas, and may serve as a resource for immunotherapy development.

Abstract
Objective: To explore the application of cortical bone trajectory screw (CBTS) and sacral alar screw (SAS) internal fixation in the treatment of lumbar adjacent segment degeneration (ASD) and evaluate its clinical effect. Methods: Data of 24 patients who were diagnosed with ASD and treated by CBTS or SAS in Beijing Chaoyang Hospital were retrospectively reviewed. There were 14 males and 10 females with a mean age of (67.9±8.2) years. The patients were followed-up for (2.6±0.4) years. Perioperative parameters including operation time, intraoperative blood loss and postoperative time on the ground were counted. All patients were followed-up for at least 2 years. Visual analogue scale (VAS) and the Oswestry disability index (ODI) were compared between pre-operation and at the last follow-up. The internal fixation-related complications, pseudarthrosis and adjacent re-degeneration were evaluated in the follow-up. Results: There were 14 proximal ASD patients, 8 distal ASD patients, 1 both ends ASD patient and 1 ASD patient in between the fusion surgeries. Bone mineral density (BMD) T score of the adjacent vertebrae was -1.98±0.91 on average. The ASD patients were re-operated with CBTS and SAS internal fixation technique. A small incision was made in the revision surgery and the original fixation was not completely cut open and removed. The mean operation time was (125±36) min, mean blood loss was (85±33) ml. The postoperative ambulation time was (3.1±1.9) days, and the hospitalization time was (9.0±2.6) days. Before the operation, the average VAS (back pain) score was 5.2±1.0, the average of VAS (leg pain) score was 6.8±1.9 and ODI was 56.6%±12.8%. VAS score was reduced to 1.4±0.6 (waist pain) and 0.9±0.4 (leg pain). ODI was improved to 13.8%±6.3%. All the difference between preoperative and the last follow-up was statically significant (all P<0.01). No internal fixation failure, pseudarthrosis and adjacent re-degeneration were observed in the final follow-up. Conclusion: The application of CBTS and SAS internal fixation techniques in the surgical treatment of lumbar ASD has the advantages of less trauma, faster postoperative recovery, reliable internal fixation, and fewer complications, especially in patients with low bone mineral density.

Abstract
With the popularization of health screening and the widespread use of low-dose computed tomography, the detection rate of lung nodules has increased year after year. However, the false positive rates testified by surgery of these lung nodules are still high. Therefore, it is vital in clinical practice to avoid overtreatment or undertreatment. But a series of problems on how to make an accurate diagnosis, how to reduce the psychological pressure of patients and follow up with regular imaging, how to clarify the indications for surgery and adopt the most minimally invasive diagnosis and treatment methods, etc. remain unsolved. Over the past decade, the diagnostic techniques for pulmonary nodules have improved significantly, including imaging progress such as the optimization of traditional imaging techniques (CT, MRI) and the emergence of new technologies (radiomics, artificial intelligence). In addition, histological improvements including percutaneous transthoracic needle biopsy, bronchoscopy, and minimally invasive surgical biopsy, etc. have brought more reliable and precise options for characterization of pulmonary nodules.

Abstract
OBJECTIVE To determine whether electroacupuncture (EA) or moxibustion-like stimulation (MLS) can affect the cutaneous and/or systemic hypothalamic-pituitary-adrenal (HPA) axes. METHODS Rats were divided into Control, EA, 37°C MLS and 43.5°C MLS groups. EA and MLS were performed at bilateral ST36 or LI4. The expression of corticotropin-releasing factor (CRF), adrenocorticotropic hormone (ACTH) and the glucocorticoid receptor (GR) was detected in local cutaneous tissues at the site of ST36 and LI4 by immunohistochemical staining. In addition, levels of CRF, ACTH and corticosterone (CORT) in cutaneous tissue and plasma were determined. RESULTS Cutaneous expression of CRF, ACTH and GR significantly increased after EA at ST36, while only GR increased after 43.5°C MLS at ST36. The results of EA and MLS at LI4 were in parallel with those at ST36. In plasma, compared with the control group, the level of CORT increased after EA at ST36, while both ACTH and CORT were markedly increased after 43.5°C MLS. For LI4, plasma CRF and CORT increased after EA, while the levels of all three hormones increased following 43.5°C MLS. Notably, compared with the effect of EA, 43.5°C MLS at ST36 produced a more substantial increase in plasma CORT, and 43.5°C MLS at LI4 induced a more dramatic increase in plasma CRF and CORT. CONCLUSION Both EA and 43.5°C MLS can activate the cutaneous and systemic HPA axes of the rat. EA tended to activate the local cutaneous HPA, while 43.5°C MLS was more likely to activate the systemic HPA axis.

Abstract
Objective: To verify the safety and feasibility of sacral alar screw fixation and fusion surgery in lumbosacral area. Methods: The clinical and radiological data of patients receiving L5/S1 single-level cortical bone trajectory screw combined with sacral alar screw decompression fixation and fusion in Beijing Chaoyang Hospital due to lumbar spinal stenosis from January 2019 to January 2020 were retrospectively analyzed. The clinical data included operation duration, intraoperative blood loss, postoperative drainage, pain and function scores during follow-up. The radiological data included preoperative and postoperative follow-up X-rays and three-dimensional reconstruction of lumbar spine CT. The fusion status and complication of internal fixation, such as screw loosening and fixation failure were evaluated by the radiological examination. Results: According to the inclusion and exclusion criteria, a total of 16 patients (7 males and 9 females) were included, with an average age of (69.6±5.2) years. The patients were followed-up for (16.2±1.7) months. The average operation duration was (144±21) min, the intraoperative blood loss was (103±20) ml, and the postoperative drainage was (80±34) ml. The patient's low back pain visual analogue scale (VAS) score was 6.8±1.0 before surgery, and it was improved to 0.9±0.7 at the last follow-up; leg pain VAS score was 6.1±0.9 before the operation and it improved to 0.9±0.7 at the last follow-up; Oswestry disability index (ODI) function score was 66.2%±8.0% before the surgery and it decreased to 26.6%±7.2% at the last follow-up. No neurological complications, surgical site infection, screw loosening, internal fixation failure or cage displacement were observed during the follow-up. The fusion rate was 68.8% (11/16) at 6 months post operation. Conclusion: It is safe, feasible and effective to apply cortical screws combined with sacral alar screws in short-segment decompression, fixation and fusion surgery on the lumbosacral region to treat lumbosacral spinal stenosis.

Abstract
COVID-19, caused by SARS-COV-2, has the characteristics of world epidemic, highly infectious and large base of death. In China, transmission route of SARS-COV-2 has been contained so effectively that COVID-19 has been well controlled due to the proactive national prevention and control strategy. However, not only does it bring a huge impact on the existing medical structure model, but also an objective impact on the treatment of patients with chronic diseases such as malignant tumors. Based on the progress reported in the domestic and international literatures and the actual management experience of our team, this paper reflects on the treatment strategies for patients with gastrointestinal stromal tumor (GIST) during the epidemic period of COVID-19. We focus on risk stratification for primary GIST and forming treatment strategies accordingly. Major considerations include the impact of delayed operation, the burden of medical resources, the waiting time for elective operation, and the principle of emergency operation. In addition, we focus on the level of evidence for non-surgical approaches with a view to developing a holistic strategy of "priority management principles" to guide clinical treatment in the context of limited resources and different GIST priorities.

Abstract
Acupuncture is an effective alternative therapy for pain management. Evidence suggests that acupuncture relieves pain by exciting somatic afferent nerve fibers. However, the mechanism underlying the interaction between neurons in different layers of the spinal dorsal horn induced by electroacupuncture (EA) remains unclear. The aim of this study was to explore the mechanism of EA relieving inflammatory muscle pain, which was associated with activation of the spontaneous firing of low-threshold mechanoreceptor (LTM) neurons and inhibition of wide dynamic range (WDR) neuronal activities in the spinal dorsal horn of rats. Inflammatory muscle pain was induced by injecting complete Freund’s adjuvant into the right biceps femoris muscle. EA with intensity of threshold of A fibers (Ta) in Liangqiu (ST34) muscle considerably inhibited the abnormal spontaneous activities of electromyography (EMG) due to muscle inflammation. While EA with intensity of C-fiber threshold (Tc) increased the abnormal activities of EMG. EA with Ta also ameliorated the imbalance of weight-bearing behavior. A microelectrode array with 750-μm depth covering 32 channels was used to record the neuronal activities of WDR and LTM in different layers of the spinal dorsal horn. The spontaneous firing of LTM neurons was enhanced by EA-Ta, while the spontaneous firing of WDR neurons was inhibited. Moreover, EA-Ta led to a significant inverse correlation between changes in the frequency of WDR and LTM neurons (r = −0.64, p < 0.05). In conclusion, the results indicated that EA could alleviate inflammatory muscle pain, which was associated with facilitation of the spontaneous firing of LTM neurons and inhibition of WDR neuronal activities. This provides a promising evidence that EA-Ta could be applied to relieve muscular inflammatory pain in clinical practice.

Abstract
The root of Angelica sinensis is one of the most widely used traditional Chinese medicines. In commercial planting, early bolting and flowering (EBF) of ca. 40% of 2-year-old plants reduces root yield and quality. Although changes in physiology in bolted plants have been investigated, the mechanism activating EBF has not been identified. Here, transcriptomics profiles at four different growth stages (S1 to S4) were performed, gene expression was validated by qRT-PCR and the accumulation of endogenous hormones quantified by HPLC. A total of 60,282 unigenes were generated, with 2,282, 1,359 and 2,246 differentially expressed genes (DEGs) observed at S2 versus S1, S3 versus S2 and S4 versus S3, respectively; 558 genes that co-exist in at least three stages from S1 to S4 were obtained. Functional annotation classified 38 DEGs linked to flowering pathways: photoperiodism, hormone signalling, carbohydrate metabolism and floral development. The levels of gene expression, hormones (GA1 , GA4 and IAA) and soluble sugars were consistent with the EBF. It can be concluded that the EBF of A. sinensis is controlled by multiple genes. This integrated analysis of transcriptomics, together with targeted hormones and soluble sugars, provides new insights into the regulation of EBF of A. sinensis.

Abstract
OBJECTIVE To observe the effect of five-element acupuncture on the cognitive function repair of migraine patients with depression/anxiety disorder. METHODS The migraine patients with depression/anxiety disorder (19 cases, 5 cases dropped off) were taken as the observation group, and received five-element acupuncture twice a week for 8 weeks. Healthy subjects (19 cases) were selected by demographic data matching as the control group. The cognitive function was evaluated with the event related potential (ERP) technique, and the latency and amplitude of visual evoked potential P300 were adopted as the observation indexes. The headache days (every 4 weeks), headache intensity [visual analogue scale(VAS) score], and headache impact test-6 (HIT-6) score, Hamilton depression scale (HAMD) score and Hamilton anxiety scale (HAMA) score were used as the observation indexes for curative effect. RESULTS Before the treatment, latency of target stimulus at Fz [ (417.5±34.3) ms] in the observation group was extended compared with the healthy subjects of the control group [(388.6±42.1) ms, P<0.05]. In the observation group, the latency of each point target stimulus [Fz: (376.1±36.2) ms, F3: (374.8±37.6) ms, F4: (372.0±37.6) ms] after treatment were shorter than those [Fz: (417.5±34.3) ms, F3: (417.4±33.8) ms, F4: (416.0±36.6) ms] before treatment (P<0.05). Before and after treatment, there was no significant difference in the amplitude of each point between the observation group and the control group (P>0.05). In the observation group, the headache days was shorter than that before treatment (P<0.01), and the VAS score, HIT-6 score, HAMD score and HAMA score were all lower than before treatment (P<0.01). CONCLUSION There are some cognitive impairments in migraine patients with depression/anxiety disorder. Five-element acupuncture not only relieves headache, anxiety and depression effectively, but also improves the activation level of the frontal lobe. It significantly repairs the impaired cognitive function.

Abstract
OBJECTIVE To compare the effect of electroacupuncture (EA) and transcutaneous electrical acupoint stimulation (TEAS) of skin and muscle layers of "Liangqiu" (ST34) area on inflammatory muscular pain in rats, so as to study the role of different-layer afferent nerve fibers in acupuncture analgesia. METHODS A total of 120 male SD rats were used in the present study, including 8 rats used for determining the excitatory threshold of Aδ(Ta) and C (Tc) afferent nerve fibers, 48 employed for comparing the analgesic effect of EA and TEAS at intensities of Ta and Tc, and 64 for observing the effect of EA and TAES stimulation of ipsilateral (Ipsi), contralateral (Contra) ST34 and ipsilateral LI4 at Ta and Tc intensities. Inflammatory muscle pain was induced by injection of complete Freund's adjuvant (CFA) into the right biceps femoris muscle. In the second part of the present study, 48 rats were randomly and equally divided into control, model, TEAS-Ta, TEAS-Tc, EA-Ta and EA-Tc groups, while in the 3rd part, 64 rats were randomly and equally divided into control, model, Ipsi-ST34-TEAS, Contra-ST34-TEAS, Ipsi-ST34-EA, Contra-ST34-EA, Ipsi-LI4-TEAS and Ipsi-LI4-EA groups. TEAS or EA was applied to the skin and muscle layers, respectively. Before and after modeling, the animal was forced to stand on a bipedal equilibrator, the difference in body mass distribution of both feet (bearing difference) was used to assess the pain severity. The frequency of myoelectrical discharges of the right bicep femoris muscle in responding to electrical stimulation of the spot between the 4th and 5th toes of the ipsilateral hindlimb at an intensity of two-folds of C-fiber excitatory threshold was recorded. RESULTS 1) The bearing difference between the bilateral hindlimbs was markedly higher in the model group than in the control group (P<0.01), and significantly lower at the 2nd and 3rd day in the EA-Ta and EA-Tc, and TEAS-Tc groups relevant to the model group (P<0.05, P<0.01). 2) The frequency of C-fiber reflex induced electromyogram (EMG) activities were significantly decreased at 0 and 1 min after TEAS of both ipsilateral ST34 at Tc, and 0 min after TEAS of the contralateral ST34 at Tc (rather than at Ta and not LI4 even at Tc) in comparison with pre-TEAS, and 0, 1 and 2 min after TEAS of ipsilateral ST34 at Tc, and 0 min after TEAS of contra-ST34 at Tc compared with the model group, respectively (P<0.01, P<0.05). In comparison with pre-EA, the frequency of C-fiber reflex induced EMG activities were significantly decreased at 0 and 1 min after EA of the ipsilateral ST34 at Ta, and 0 min after EA of the contra-ST34 at Ta. In addition, the frequency of C-fiber reflex induced EMG activities were decreased at 0, 1 and 2 min after EA of the ipsilateral ST34 at Tc, and 0 and 1 min after EA of the contra-ST34 at Tc, as well as 0 min after EA of LI4 at Tc (P<0.01, P<0.05).In comparison with the model group, the frequency of C-fiber reflex induced EMG activities are significantly decreased at 0, and 1 min after EA of the ipsilateral ST34 at Ta, and 0 min after EA of the contra-ST34 at Ta. In addition, the frequency of C-fiber reflex induced EMG activities were decreased at 0, 1 ,2,and 3 min after EA of the ipsilateral ST34 at Tc, and 0 and 1 min after EA of the contra-ST34 at Tc, as well as 0 min after EA of LI4 at Tc, respectively (P<0.01, P<0.05). CONCLUSION TEAS-ST34 at Tc and EA-ST34 at both Ta and Tc can alleviate pain behavior in inflammatory pain rats, which may be related to its effect in activating the afferent nerve fiber in different layers of ST34 area.

Abstract
It has been reported that rs67085638 in long non-coding RNAs (lncRNA)-CCAT1 was associated with the risk of tumorigenesis. Also, CCAT1 could affect chemoresistance of cancer cells to paclitaxel (PTX) via regulating miR-24-3p and FSCN1 expression. In this study, we aimed to investigate the effect of rs67085638 on the expression of CCAT1/miR-24-3p/FSCN1 and the response of colon cancer to the treatment of PTX. 48 colon cancer patients were recruited and grouped by their genotypes of rs67085638 polymorphism as a CC group (N = 28) and a CT group (N = 20). PCR analysis, IHC assay and Western blot, TUNEL assay and flow cytometry were conducted. LncRNA-CCAT1 and FSCN1 mRNA/protein were overexpressed, whereas miR-24-3p was down-regulated in the CT-genotyped patients and cells compared with those in the CC-genotyped patients and cells. The survival of colon cancer cells was decreased, whereas the apoptosis of colon cancer cells was increased by PTX treatment in a dose-dependent manner. MiR-24-3p was validated to target lncRNA-CCAT1 and FSCN1 mRNA, and the overexpression of CCAT1 could reduce the expression of miR-24-3p although elevating the expression of FSCN1. Knockdown of lncRNA-CCAT1 partly reversed the suppressed growth of CT-genotyped tumours. And the knockdown of lncRNA-CCAT1 partly reversed the dysregulation of lncRNA-CCAT1 and FSCN1 mRNA/protein in rs67085638-CT + NC shRNA mice. The findings of this study demonstrated that the presence of the minor allele of rs67085638 increased the expression of CCAT1 and accordingly enhanced the resistance to PTX. Down-regulation of CCAT1 significantly re-stored the sensitivity to PTX of colon cancer cells.

Abstract
OBJECTIVE To observe the effect of electroacupuncture (EA) at sensitized acupoints on choline acetyltransferase positive (ChAT+) neurons in dorsal motor nucleus (DMV) of brainstem vagus in the colitis model rats and explore the mechanism of the improvement in colonic inflammatory injury in the rats. METHODS A total of 79 male SD rats were randomized into five groups, i.e. a normal group (20 rats), a normal plus sensitized acupoint group (5 rats), a model group (34 rats), an EA-1 group (15 rats) and an EA-2 group (5 rats). In the model group and the EA groups, 5% dextran sulfate sodium (DSS) was adopted for 6-day free drinking to establish colitis model rats. By injecting Evans blue (EB) into the caudal vein in the model rats, the sensitized acupoints were determined. Afterwards, in the normal plus sensitized acupoint group, the EA-1 group and the EA-2 group, EA was exerted at the sensitized acupoints, with disperse-dense wave, 2 Hz/ 15 Hz in frequency and 2 mA in intensity, for 30 min of intervention each day. The intervention lasted for 6 days in the EA-1 group and for 1 day in both the normal plus sensitized acupoint group and the EA-2 group. On day 0, 7 and 13 of experiment, successively, the score of disease activity index (DAI), the score of colonic histological damage, as well as the changes in the mechanical paw withdrawal threshold and thermal paw withdrawal latency were evaluated in the normal group, the model group and the EA-1 group. On day 7 of experiment, using immunofluorescence staining, the activation of different lamina neurons of spinal dorsal horn and ChAT+ neurons in DMV was observed in the normal group, the normal plus sensitized acupoint group, the model group and the EA-2 group separately. RESULTS The EB extravasating areas were distributed in the segments from T12 to S1 on the body surface of colitis model rats, mainly focusing at L2 and L5. Therefore, "Shangjuxu" (ST 37) was taken as the sensitized acupoint. Compared with the normal group on day 7 and 13 of experiment, the mechanical paw withdrawal threshold were reduced (P<0.001), DAI scores and the scores of colonic histological damage were increased (P<0.001) in the model group. Compared with the normal group on day 7 of experiment, thermal paw withdrawal latency in the model group was reduced (P<0.001). Compared with the model group on day 13 of experiment, the mechanical paw withdrawal threshold was increased (P<0.001), DAI score and the score of colonic histological damage were reduced (P<0.01, P<0.05) in the EA-1 group. Compared with the normal group, the activated numbers of the neurons in superficial laminae (Ⅰand Ⅱ) at spinal dorsal horn of L4 to L6 and ChAT+ neurons in DMV were increased in the normal plus sensitized acupoint group and the model group (P<0.05, P<0.01). Compared with the normal plus sensitized acupoint group and the model group, the activated numbers of the neurons in superficial laminae at spinal dorsal horn of L4 to L6 and ChAT+ neurons in DMV were increased in the EA-2 group (P<0.001). CONCLUSION The segmental dominance (acupoints) from T12 to S1 on the body surface of colitis rats is sensitized. EA at sensitized acupoints effectively relieves colonic inflammatory injury, which is probably by activating superficial lamina neurons of spinal dorsal horn and ChAT+ neurons of DMV.

Abstract
OBJECTIVE To observe and compare the ameliorate effects of electroacupuncture (EA) and transcutaneous electrical acupoint stimulation (TEAS) with different intensities on inflammatory muscle pain, so as to confirm the role of different afferent nerve fibers in different layers (skin or muscle) in pain relief of acupuncture. METHODS The intensities of the thresholds of A (Ta) and C (Tc) were selected for TEAS and EA. TEAS and EA were applied on the layer of skin and muscle of "Liangqiu" (ST34), respectively. Forty-eight rats were randomly divided into control, model, TEAS-Ta, TEAS-Tc, EA-Ta and EA-Tc groups (n=8 in each group). The inflammatory muscle pain model was established by complete Freund's adjuvant (CFA) injection into the right biceps femoris muscle. EA or TEAS was applied once a day for 3 days. The weight difference between the hind limbs and the abnormal electromyography (EMG) activities were observed as an index for pain of the rats. RESULTS After modeling, the weight difference between the hind limbs was increased markedly in the model group relevant to the control group (P<0.01). Compared with the model group, the weight difference between the hind limbs in the TEAS-Tc, EA-Ta, and EA-Tc groups was significantly decreased (P<0.05, P<0.01). Compared with that before intervention, the area under the curve and discharge frequency of abnormal EMG of rats in the TEAS-Tc and EA-Ta groups were significantly reduced after intervention (P<0.01, P<0.05), while those in the EA-Tc group were significantly increased (P<0.05). After the intervention, compared with the TEAS-Ta group, the inhibition rate of the area under the curve and the discharge frequency of the abnormal EMG in the TEAS-Tc group increased significantly (P<0.05); and those were also increased in the EA-Ta group when compared with the EA-Tc group (P<0.01). CONCLUSION TEAS with Tc or EA with Ta in the muscle layer can alleviate the pain and inhibit the abnormal EMG in inflammatory muscle pain rats. It is indicated that local pain relief by acupuncture was related to the afferent nerve fiber in different layer with different intensities.

Abstract
Objective: To investigate the damage and mechanism of artemisia annua pollen on tight junction of human nasal mucosa epithelial cells (HNEpC). Methods: HNEpC were cultured in vitro. Different concentrations of artemisia annua pollen (0, 20, 40, 80, 100, 160, 200 μg/ml) were used to intervene the cells for 24 h, and the cell proliferation activity was detected by the CCK-8 method. The expression and phosphorylation of p38MAPK signaling pathway were detected by Western Blot before and after the intervention of SB203580, a p38MAPK inhibitor in HNEpC. Immunofluorescence chemical staining, Western Blot and quantitative real-time PCR (qPCR) were used to observe the expression and distribution of tight junctions Occludin and Claudin-1. SPSS 21.1 software was used for statistical analysis. Results: CCK-8 results showed that, compared with the control group, the proliferation activity of HNEpC increased after 6 h intervention with different concentrations of artemisia annua pollen (all P<0.05). After 12 h of intervention, the proliferation activity of HNEpC in the 20, 40, 80, 100 and 160 μg/ml groups was not significantly changed (all P>0.05), while that in the 200 μg/ml group was decreased (P<0.05). After the intervention for 24 h, the proliferation activity of cells in the 20 and 40 μg/ml groups was not significantly changed (all P>0.05), while that in the 80, 100, 160 and 200 μg/ml groups was decreased (all P<0.05). Immunofluorescence staining showed that the Occludin and Claudin-1 proteins in the normal control group were localized on the cell membrane and expressed more and formed a ring structure around the cell membrane. However, under the intervention of high concentration artemisia annua pollen, its expression level decreased, appeared broken, fuzzy, and nonuniform distribution. Western Blot and qPCR results showed that after 24 h of intervention, the expression levels of HNEpC Claudin-1 protein and its mRNA in the pollen groups (40, 80, 100, 160, 200 μg/ml) of artemisia annua decreased compared with those of those of the control group (mRNA expression levels were 0.567±0.214, 0.443±0.109, 0.462±0.160, 0.497±0.134, 0.388±0.076 compared with 1.001±0.067, respectively, all P<0.05). However, the mRNA of Occludin protein and its mRNA only decreased in the 200 μg/ml treatment group (mRNA expression level was 0.631±0.109 compared with 1.016±0.026, P<0.05), while all the other treatment groups increased (mRNA expression levels were 1.258±0.134, 1.827±0.103, 2.429±0.077, 1.707±0.085, 1.477±0.066 compared with 1.016±0.026, respectively, all P<0.05). Western Blot showed that p-p38MAPK expression increased after intervention with 100, 160, 200 μg/ml artemisia annua pollen for 24 h. SB203580 could inhibit the decreasing expression of Occludin caused by artemisinin pollen (mRNA expression was 1.255±0.179 compared with 0.631±0.109, P<0.05), but had no effect on Claudin-1 protein expression. Conclusion: Pollen from artemisia annua may activate p38MAPK signaling pathway and destroy the close connection of HNEpC.

Abstract
Objective: To explore the temporal and spatial characteristics of pneumoconiosis in Hebei Province from 2009 to 2018, and to provide evidence for the policy development of pneumoconiosis prevention and control. Methods: In February 2019, a database of pneumoconiosis incidence from 2009 to 2018 in Hebei Province was built. The spatial-temporal distribution of pneumoconiosis in Hebei Province was displayed based on barycenter migration technology and spatial autocorrelation analysis. Results: A total of 6099 cases of pneumoconiosis were reported in Hebei Province from 2009 to 2018, the top 5 pneumoconiosis were silicosis(4399, 72.13%) , coal worker pneumoconiosis (1298 , 21.28%) , ceramics pneumoconiosis (224, 3.67%) , welding worker's pneumoconiosis(76, 1.25%) , and casting worker's pneumoconiosis(48, 0.79%). The focus of pneumoconiosis from 2009 to 2014 moved from Tangshan in the northeast to Zhangjiakou in the northwest, and moved to Chengde in the north from 2015 to 2017, and moved back to Tangshan in 2018. The incidence of pneumoconiosis was globally autocorrelation (P <0.05) from 2009 to 2011 and 2014 to 2018. The high-high gathering areas were located in Zhangjiakou, Chengde and other areas. Conclusion: The barycenter of pneumo- coniosis in hebei province from 2009 to 2018 is relatively stable, mainly locates in the northern part of Hebei Province over the years. There is an obvious regional aggregation, and the aggregation type is mainly high-high aggregation, which indicates that relevant departments should focus on strengthening the prevention and treat- ment of aggregation areas on the basis of overall planning.

Abstract
Cancer metastasis, a leading cause of death in patients, is associated with aberrant expression of epigenetic modifiers, yet it remains poorly defined how epigenetic readers drive metastatic growth and whether epigenetic readers are targetable to control metastasis. Here, we report that bromodomain-containing protein 4 (BRD4), a histone acetylation reader and emerging anticancer therapeutic target, promotes progression and metastasis of gastric cancer. The abundance of BRD4 in human gastric cancer tissues correlated with shortened metastasis-free gastric cancer patient survival. Consistently, BRD4 maintained invasiveness of cancer cells in vitro and their dissemination at distal organs in vivo. Surprisingly, BRD4 function in this context was independent of its putative transcriptional targets such as MYC or BCL2, but rather through stabilization of Snail at posttranslational levels. In an acetylation-dependent manner, BRD4 recognized acetylated lysine 146 (K146) and K187 on Snail to prevent Snail recognition by its E3 ubiquitin ligases FBXL14 and β-Trcp1, thereby inhibiting Snail polyubiquitination and proteasomal degradation. Accordingly, genome-wide transcriptome analyses identified that BRD4 and Snail regulate a partially shared metastatic gene signature in gastric cancer cells. These findings reveal a noncanonical posttranscriptional regulatory function of BRD4 in maintaining cancer growth and dissemination, with immediate translational implications for treating gastric metastatic malignancies with clinically available bromodomain inhibitors. SIGNIFICANCE: These findings reveal a novel posttranscriptional regulatory function of the epigenetic reader BRD4 in cancer metastasis via stabilizing Snail, with immediate translational implication for treating metastatic malignancies with clinically available bromodomain inhibitors.

Abstract
Gastric cancer (GC) is the fourth leading cause of gynecological malignancies worldwide. 5-fluorouracil (5-FU)-mediated chemotherapy is the adjuvant treatment for patients with GC following surgical resection. Many studies have indicated the cancer-type specific roles of forkhead box protein A1 (FOXA1) and keratin 7 (KRT7) in human malignancies. However, the potential mechanism underlying the involvement of FOXA1 and KRT7 in the pathogenesis and chemoresistance of GC are still not entirely clear. In our study, gain- and loss-of-function experiments proved that FOXA1 promoted cell proliferation, migration and invasion in AGS and SGC-7901 cells. Consequently, KRT7 was identified to be transcriptional activated by FOXA1 using Dual luciferase reporter assay. Our results also indicated that FOXA1 exerted its functions in enhancing viability and invasion of AGS and SGC-7901 cells through activating KRT7. Finally, interference of FOXA1 or KRT7 increased the chemosensitivity of AGS and SGC-7901 cells to 5-fluorouracil (5-Fu) treatment by suppressing cell proliferation. In conclusion, these data indicate that FOXA1 promoted proliferation, migration, invasion, and decreased chemosensitivity of GC cells to 5-Fu treatment through transcriptional activator KRT7. The present study provides a novel therapeutic strategy for the enhancement of efficacy in GC treatment and provides important insights into the molecular mechanism underlying 5-FU-mediated chemoresistance.

Abstract
It is well known that parenteral and enteral nutrition support is helpful to improve clinical outcomes in patients with malnutrition or nutritional risk, and surgical nutrition has been used in China for 40 years. However, there is still insufficient awareness of malnutrition among clinical workers. There were different opinions from many experts after the publications of the European Society for Parenteral and Enteral Nutrition (ESPEN) consensus of malnutrition assessment 2015 and ESPEN guidelines on definitions and terminology of clinical nutrition 2017. Global Leadership Initiative on Malnutrition (GLIM) criteria for the diagnosis of malnutrition has also been published in 2018. Though it is lack of clinical validation, it is a big step forward. In order to achieve better prevention and treatment of malnutrition in clinical work, this present paper analyzes and compares the core contents of malnutrition assessment (diagnosis) in recent years, proposes current practical strategy for Chinese clinical workers, emphasizes that GLIM criteria cannot replace the three steps named "screening-assessment-intervention" .

Abstract
OBJECTIVE To summarize the research progress of acupuncture-moxibustion and the related adjuvant therapy for promoting pressure ulcer healing in recent 10 years and explore the future research direction. METHODS By retrieving Chinese Journal Full-text Database (CNKI), VIP Database (VIP) and PubMed database, dated from January 2008 through to December 2017, the articles for the treatment of pressure ulcers with acupuncture-moxibustion and the related adjuvant therapy were collected. In terms of clinical research and experimental research, the research progress and the related effect mechanisms were analyzed and summarized. RESULTS Through screening, 78 articles for the treatment of pressure ulcer with acupuncture-moxibustion and the adjuvant therapy were collected finally, of which, 71 articles were Chinese and 7 articles were English. The therapies with the highest frequency for pressure ulcer were the simple moxibustion or moxibusiton combined with other adjuvant measures. The local surrounding needling therapy, electroacupuncture, transcutaneous electrical nerve stimulation (TENS), neuromuscular electrical stimulation (NMES) and laser therapy were followed by regarding the use frequency. All of these interventions promoted the healing of pressure ulcers to different degrees. The underlying mechanisms were related to the regulation of the local blood perfusion, differentiation and migration of vascular endothelial growth factor, angiogenesis, superoxide dismutase SOD and eNOS/NO signaling pathway so as to promote tissue migration and proliferation. CONCLUSION Acupuncture-moxibustion and the related adjuvant therapies achieve the definite therapeutic effects on pressure ulcers. The researches on the treatment of pressure ulcers at home and abroad are diversified, but it is still limited in the research on the effect mechanism.

Abstract
OBJECTIVE Our previous study demonstrated that moxibustion could promote skin wound healing in rats with full-thickness cutaneous wounds. The present study was designed to observe the effect of moxibustion on the levels of pro-inflammatory and anti-inflammatory cytokines, and proliferation of vascular endothelial cells, so as to explore its mechanisms underlying facilitating wound-healing. METHODS A total of 84 adult SD male rats were randomly assigned to normal (n=6), model(n=39)and moxibustion(n=39)groups. The skin wound model was established by removal of a piece of full-thickness skin from the median line of the rats' back (about 2 cm below the shoulder blade). Moxibustion was applied to the surrounding area of the focus for 25 min, once daily for 6 days. The blood samples were collected at day 1, 2, 3 and 5 after modeling for assaying serum contents of IL-1α, IL-1β, IL-6, IL-4, IL-10, IL-13, granulocyte-colony stimulating factor (G-CSF), granulocyte macrophagecolony stimulating factor (GM-CSF, an inflammatory mediator), macrophage inhibitory protein-1α (MIP-1α) and vascular endothelial growth factor (VEGF) with liquid chip methods, and the topical wound tissues were collected after trans-cardiac perfusion with 4% paraforma-ldehyde solution for detecting the expression of CD31 proteins by using immunofluorescence staining. RESULTS After modeling and in comparison with the model group, the contents of serum IL-1α and IL-6 at the 1st day were significantly increased (P<0.05), but notably decreased at the 3rd day after modeling in the moxibustion group (P<0.05). The contents of serum IL-1β on day 1 and 2 were significantly higher in the moxibustion group than those of the model group (P<0.05). After moxibustion, the contents of serum IL-4 and IL-10 were significantly up-regulated on day 1 after modeling (P<0.05), and obviously down-regulated from the 3rd day on (P<0.05). The contents of serum MIP-1α on the 2nd day and serum VEGF on day 1 and 2, and wound-skin VEGF on day 5 were obviously up-regulated in the moxibustion group in comparison with the model group (P<0.05, P<0.01).. CONCLUSION Moxibustion promotes the inflammatory response by regulating the levels of both pro-inflammatory and anti-inflammatory cytokines in the early phase of skin wounds in rats, which may be in favor of the transformation from the inflammatory phase to the proliferation phase in advance, promoting wound healing at last.

Abstract
Objective: To evaluate the efficacy and safety of cortical screw fixation in posterior lumbar spine fixation with cortical bone trajectory (CBT) fixation or pedicle screw (PS) fixation in posterior lumbar fusion. Methods: It was a prospective study and CBT or PS for the treatment of lumbar disease from August 2015 to August 2017 in Beijing Chaoyang Hospital were analyzed. There were 53 males and 51 females, aged 56-78 years (mean age, (67±5) years). The patient's gender, age, operative time, intraoperative blood loss, postoperative bleeding, postoperative hospital stay, and postoperative patient satisfaction were collected. The Oswestry disability index (ODI) and visual analogue scale (VAS) of back pain were used to evaluate preoperative and half-year, one-year and two-year postoperative function and quality of life. Complications such as wound infection, cage displacement, screw extraction and fixation fracture were compared between the two groups. The data of normal distribution were compared with Student t test between the two groups. Results: There was no significant difference in the operation time between the CBT group (n=50) and the PS group (n=54) ((223±17) min vs (221±16) min, t=0.74, P=0.46). The intraoperative blood loss and wound drainage volume were significantly lower in the CBT group than those in the PS screw group (t=-24.20, -57.62, both P<0.05). The average length of hospital stay in the CBT group was significantly shorter than that in the PS group (t=-7.65, P=0.00). Patients with CBT screws had better postoperative satisfaction than patients in PS group (91±6 vs 86±7, t=3.89, P=0.00). The ODI score in the CBT group was significantly lower than that in the PD screw group half a year after the operation (3.9±1.9 vs 5.8±3.1, t=-3.66, P=0.00). The VAS and ODI scores in the CBT group were significantly lower than those in the PS group 1 year after the surgery (t=-3.03, -4.09, both P<0.05). There was no significant differences in wound infection, cage displacement, screw extraction and fixation fracture between the two groups. Conclusion: CBT screw technique is minimally invasive, with short operation time, less intraoperative blood loss, rapid postoperative recovery and low complications. It can be effectively used in posterior lumbar cone fusion.

Abstract
OBJECTIVE To explore the effects of moxibustion intervention on wound healing in rats with full-thickness cutaneous wounds. METHODS A total of 28 adult SD male rats were randomly assigned to model group and moxibustion group (n=14 in each one). The skin wound model was established by removal of a piece of full-thickness skin from the median line of the rats' back (about 2 cm below the shoulder blade). Moxibustion intervention was applied to the surrounding area of the focus for 25 min, once daily for 6 days. The wound healing was observed and photographed after each moxibustion intervention. The wound tissues were harvested after transcardiac perfusion with 4% paraformaldehyde solution on the 2nd and 7thday after modeling, and stained with H.E. and Masson methods for displaying histopathological changes and collagen fiber growth status, respectively. RESULTS After modeling, the cutaneous wound was healed gradually in both groups, and the wound area was significantly smaller from the 2nd day to the 5th day in the moxibustion group than in the model group (P<0.01, P<0.05). Correspondingly, the wound closure area was significantly bigger from the 2nd to the 5th day in the moxibustion group than in the model group (P<0.01). H.E. and Masson staining showed that the number of the inflammatory cells (monocytes, macrophages, neutrophile, etc.) and the collagen fiber area in the local wound tissue of the moxibustion group were significantly bigger than those of the model group on the 2nd day after intervention (P<0.01). After 6 sessions of moxibustion intervention, the number of fibroblasts and collagen fibers in the moxibustion group were obviously increased than that in the model group, characterized by closer arrangement of fibroblasts and collagen fibers, more and larger of the new-born blood vessels, and thicker of the scab in the wound area. CONCLUSION Moxibustion can promote the wound healing by enhancing the growth of collagen fibers and cell proliferation in the traumatic cutaneous area in full-thickness cutaneous wound rats.

Abstract
The NIH-funded "Stimulating Peripheral Activity to Relieve Conditions (SPARC)" program has been initiated in Octomber 2016, aiming at developing high resolution neural circuit maps and next generation neural modulation devices. This program has brought great stimulus to acupuncturists and acupuncture researchers both at home and abroad. Is the SPARC program a driving force or a challenge of acupuncture research? In the present study, we introduced the SPARC program and compared it with current acupuncture research. The first step of SPARC is to better map neural circuits associated with disease on the anatomical level so as to identify the best points for intervention, and to decode the neural language at these intervention points for developing a dictionary of patterns associated with health and disease states on the signaling level. Similarly, our acupuncture research also focuses on revealing the neural encoding of acupuncture stimulation and its effect on visceral function, seeking suitable stimulation parameters to regulate the abnormal visceral activity precisely. Therefore, the common point of SPARC program and acupuncture research is the scientific basis of peripheral somatic neuronal regulation, and their difference is that acupuncture regulates the visceral function through multiple neural circuits and neural feedbacks by stimulating the sensitized points or acupoints, achieving homeostasis at last. Acupuncture-induced regulation effect is limited and the therapy is safe. Whereas, "stimulating periphe-ral activity (SPA)" can regulate the visceral organs precisely but without neural feedback. Inevitably, SPA will produce tolerance or side effects. Therefore, there is still much work to be done in terms of the initiation of trigger stimulation and the feedback inhibition of target organ effects. The SPARC program is definitely a powerful force in revealing the mechanisms by which acupuncture works.

Abstract
Pre-mRNA alternative splicing is a conserved mechanism for eukaryotic cells to leverage existing genetic resources to create a diverse pool of protein products. It is regulated in coordination with other events in RNA metabolism such as transcription, polyadenylation, RNA transport, and nonsense-mediated decay via protein networks. SERINE/ARGININE-RICH 45 (SR45) is thought to be a neutral splicing regulator. It is orthologous to a component of the apoptosis and splicing-associated protein (ASAP) complex functioning to regulate RNA metabolism at multiple levels. Within this context, we try to understand why the sr45-1 mutant Arabidopsis has malformed flowers, delayed flowering time, and increased disease resistance. Prior studies revealed increased expression for some disease resistance genes and the flowering suppressor Flowering Locus C (FLC) in sr45-1 mutants and a physical association between SR45 and reproductive process-related RNAs. Here, we used Tandem Mass Tag-based quantitative mass spectrometry to compare the protein abundance from inflorescence between Arabidopsis wild-type (Col-0) and sr45-1 mutant plants. A total of 7,206 proteins were quantified, of which 227 proteins exhibited significantly different accumulation. Only a small percentage of these proteins overlapped with the dataset of RNAs with altered expression. The proteomics results revealed that the sr45-1 mutant had increased amounts of enzymes for glucosinolate biosynthesis which are important for disease resistance. Furthermore, the mutant inflorescence had a drastically reduced amount of the Sin3-associated protein 18 (SAP18), a second ASAP complex component, despite no significant reduction in SAP18 RNA. The third ASAP component protein, ACINUS, also had lower abundance without significant RNA changes in the sr45-1 mutant. To test the effect of SR45 on SAP18, a SAP18-GFP fusion protein was overproduced in transgenic Arabidopsis Col-0 and sr45-1 plants. SAP18-GFP has less accumulation in the nucleus, the site of activity for the ASAP complex, without SR45. Furthermore, transgenic sr45-1 mutants overproducing SAP18-GFP expressed even more FLC and had a more severe flowering delay than non-transgenic sr45-1 mutants. These results suggest that SR45 is required to maintain the wild-type level of SAP18 protein accumulation in the nucleus and that FLC-regulated flowering time is regulated by the correct expression and localization of the ASAP complex.

Abstract
Artificial microRNA (amiRNA) technology offers reversible and flexible gene inactivation and complements genome-editing technologies. However, obtaining transgenic plants with maximal gene silencing remains a major technical challenge in current amiRNA applications. Here, we incorporated an empirically determined feature of effective amiRNAs to the amiRNA design and in silico generated a database containing 533,429 gene-specific amiRNAs for silencing 27,136 genes in Arabidopsis (Arabidopsis thaliana), with a genome coverage of 98.87%. In both single-gene and multiple-gene silencing, we observed an overall improvement in performance by amiRNAs designed using our strategy in Arabidopsis protoplasts and transgenic plants. In addition, the endogenous tRNA-processing system was used to generate multiple amiRNAs from tRNA-pre-amiRNA tandem repeats for multiplex gene silencing. An intronic amiRNA-producing fluorescent reporter was explored as a visual screening strategy for transgenic Arabidopsis and rice (Oryza sativa) plants with maximal whole-plant or cell type-specific gene silencing. These improvements enable the amiRNA technology to be a functional gene knockout tool for basic and applied plant research.

Abstract
Plastic phenotype convention between glioma stem cells (GSCs) and non-stem tumor cells (NSTCs) significantly fuels glioblastoma heterogeneity that causes therapeutic failure. Recent progressions indicate that glucose metabolic reprogramming could drive cell fates. However, the metabolic pattern of GSCs and NSTCs and its association with tumor cell phenotypes remain largely unknown. Here we found that GSCs were more glycolytic than NSTCs, and voltage-dependent anion channel 2 (VDAC2), a mitochondrial membrane protein, was critical for metabolic switching between GSCs and NSTCs to affect their phenotypes. VDAC2 was highly expressed in NSTCs relative to GSCs and coupled a glycolytic rate-limiting enzyme platelet-type of phosphofructokinase (PFKP) on mitochondrion to inhibit PFKP-mediated glycolysis required for GSC maintenance. Disruption of VDAC2 induced dedifferentiation of NSTCs to acquire GSC features, including the enhanced self-renewal, preferential expression of GSC markers, and increased tumorigenicity. Inversely, enforced expression ofVDAC2 impaired the self-renewal and highly tumorigenic properties of GSCs. PFK inhibitor clotrimazole compromised the effect of VDAC2 disruption on glycolytic reprogramming and GSC phenotypic transition. Clinically, VDAC2 expression inversely correlated with glioma grades (Immunohistochemical staining scores of VDAC2 were 4.7 ± 2.8, 3.2 ± 1.9, and 1.9 ± 1.9 for grade II, grade III, and IV, respectively, p < 0.05 for all) and the patients with high expression of VDAC2 had longer overall survival than those with low expression of VDAC2 (p = 0.0008). In conclusion, we demonstrate that VDAC2 is a new glycolytic regulator controlling the phenotype transition between glioma stem cells and non-stem cells and may serves as a new prognostic indicator and a potential therapeutic target for glioma patients.

Abstract
Phytochemical investigation of the barks of Juglans mandshurica Maxim led to the isolation, purification, and identification of one new lignan named Juglansol A (1), along with nine known compounds (2-10). Their structures were determined by the results of UV, IR, CD, HRESIMS, 1D, and 2D NMR spectroscopic analysis. Compounds 1-10 were evaluated for their cytotoxicities against A549, HepG2, Hep3B, Bcap-37, and MCF-7 cell lines. The results showed that compound 2 possessed stronger cytotoxicities against the tested tumor cell lines compared with positive control 5-fluorouracil.
