Abstract
OBJECTIVE To analyze the echinococcosis surveillance results in Bayingolin Mongol Autonomous Prefecture, Xinjiang Uygur Autonomous Region from 2017 to 2022, so as to provide insights into formulation of echinococcosis control measures in the prefecture. METHODS Villagers were randomly sampled using a multistage sampling method from class I and II echinococcosis endemic counties in Bayingolin Mongolian Autonomous Prefecture from 2017 to 2022 for detection of human echinococcosis, while all patients undergoing ultrasound examinations in medical institutions in class III endemic counties received active echinococcosis screening. In addition, livestock in centralized slaughterhouses or slaughtering sites were screened for echinococcosis using the palpation and necropsy method, and fresh domestic dog feces samples were collected from randomly selected dog owners in each administrative village for detection of Echinococcus copro-antigen in domestic dogs. The trends in detection of human and livestock echinococcosis, detection of newly diagnosed human echinococcosis cases and detection of Echinococcus coproantigen in domestic dogs were analyzed in Bayingolin Mongol Autonomous Prefecture from 2017 to 2022. RESULTS The mean detection rate of human echinococcosis was 0.13% (540/407 803) in Bayingolin Mongol Autonomous Prefecture from 2017 to 2022, which appeared a tendency towards a decline over years (χ2trend = 1 217.21, P < 0.001), and the highest detection of newly diagnosed echinococcosis cases was seen in Hejing County (0.28%, 191/67 865). The detection of livestock echinococcosis appeared a tendency towards a decline over years from 2017 to 2022 (χ2trend = 147.02, P < 0.001), with the highest detection rate seen in Hejing County (3.44%, 86/2 500), and the detection of Echinococcus copro-antigen in domestic dogs appeared a tendency towards a decline over years from 2017 to 2022 (χ2trend = 302.46, P < 0.001), with the highest detection rate in Qiemo County (2.74%, 118/4 313). CONCLUSIONS The detection of human and livestock echinococcosis and dog feces antigens Echinococcus copro-antigen in domestic dogs all appeared a tendency towards a decline in Bayingolin Mongol Autonomous Prefecture, Xinjiang Uygur Autonomous Region from 2017 to 2022; however, there is still a high echinococcosis transmission risk in local areas. Sustainable integrated echinococcosis control is required in Bayingolin Mongol Autonomous Prefecture.

Abstract
AIM To investigate the improvement of image quality and visualisation of the anterolateral thigh (ALT) flap perforators on computed tomography angiography (CTA) after administration of sublingual glyceryl trinitrate (GTN). MATERIALS AND METHODS Sixty patients with oral lesions received thigh CTA examinations were divided randomly into two groups after administration of sublingual GTN (GTN group) or without administration of sublingual GTN (non-GTN group). Two radiologists calculated the signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), and assessed the image quality of each vessel. Besides, the grade of thigh artery, the lumen diameter of deep femoral artery, lateral circumflex femoral artery (LCFA), the descending branch of LCFA and its proximal and distal perforators, and the number and type of visible perforators were evaluated quantitatively. RESULTS The SNR and CNR were not significantly different between the two groups (p>0.05). The image quality of CTA in the GTN group was significantly better than that in the non-GTN group (p<0.01). The lumen diameters of the deep femoral artery, LCFA, the descending branch of LCFA and its perforators were significantly larger in the GTN group than those in the non-GTN group (p<0.01). Compared with the non-GTN group, the number of visible perforators and the number of visible septocutaneous perforators were significantly more in the GTN group, and the qualitative grade of visible perforators was significantly higher (p<0.001). CONCLUSIONS The administration of sublingual GTN in preoperative thigh CTA can improve the image quality and visualisation of perforator vessels, thus could help surgeons to select the optimum ALT flaps.

Abstract
PURPOSE/OBJECTIVE(S) Brentuximab vedotin (BV) and immune checkpoint inhibitors (ICIs) had important roles in the treatment of relapse or refractory (R/R) Hodgkin lymphoma (HL). Treatment of refractory disease after BV and -/or ICIs remains a challenge. This study was conducted to evaluate the efficacy and safety of radiotherapy for R/R HL after failure to BV or ICIs. MATERIALS/METHODS We retrospectively analyzed patients in two institutions with R/R HL who had failed after first-line therapy, and were refractory to BV or ICIs, and received radiotherapy (RT) thereafter. The overall response rate (ORR), duration of response (DOR), progression-free survival (PFS) and overall survival (OS) were analyzed. RESULTS A total of 19 patients were enrolled. First-line systemic therapy consisted of ABVD (84.2%), AVD + ICIs (10.5%) and BEACOPP (5.3%), respectively. After first-line therapy, 15 patients (78.9%) were refractory, and 4 patients (21.1%) relapsed. After diagnosis of R/R HL, 8 patients (42.1%) received BV, and 17 patients (89.5%) received ICIs. RT was delivered in all 19 patients who failed after BV or ICIs. In 16 efficacy-evaluable patients, the ORR and CR rate were 100% and 100%. The median DOR was 17.2 months (range, 7.9 to 46.7 months). 3 patients progressed at outside of the radiation field. The in-field-response rate was 100%. The 12-month PFS and OS were 84.4% and 100%, respectively. No patients were reported with sever adverse events. CONCLUSION This study concluded that radiotherapy was effective and safe for refractory HL after BV or ICIs. Further prospective studies were warranted.

Abstract
AIM To compare the diagnostic performance of mono-exponential model-derived apparent diffusion coefficient (ADC), continuous-time random-walk (CTRW) model-derived Dm, α, β and their combinations in discriminating malignancy of breast lesions, and investigate the association between model-derived parameters and prognosis-related immunohistochemical indices. MATERIALS AND METHODS A total of 85 patients with breast lesions (51 malignant, 34 benign) were analysed in this retrospective study. Clinical characteristics include oestrogen receptor (ER), progesterone receptor (PR), human epidermal receptor 2 (HER2), and Ki-67. The ADC was fitted using a mono-exponential model (b-values = 0, 800 s/mm2), while Dm, α, and β were fitted using a CTRW model. Independent Student's t-test and the Mann-Whitney U-test were used for the comparison of parameters. Discrimination performance was accomplished by receiver operating characteristic (ROC) analysis, and Spearman's correlation analysis was used to explore the association between immunohistochemical indices and diffusion parameters, the statistical significance level was p<0.05. RESULTS Dm and ADC demonstrated similar performance in differentiating malignant and benign lesions (AUC = 0.928 versus 0.930), while the combination of Dm, α, and β could improve the AUC to 0.969. The combined parameter generated by ADC, Dm, α, and β was effective in identifying the ER+/ER- and PR+/PR- patients. Temporal heterogeneity parameter α correlated significantly with the expression of PR. CONCLUSION Diffusion parameters derived from the CTRW model could effectively discriminate the malignancy of breast lesions. Meanwhile, the hormone receptor expression could be distinguished by combined diffusion parameters, and have the potential to reflect the prognosis.

Abstract
OBJECTIVE To perform an epidemiological investigation on a case of visceral leishmaniasis reported from Shule County, Kashi Prefecture, Xinjiang Uygur Autonomous Region in 2021, so as to provide insights into differential diagnosis of visceral leishmaniasis during the COVID-19 pandemic. METHODS The epidemiological history of this case was collected, and the case was diagnosed for Leishmania infection with the immunochromatographic (rK39) strip test, bone marrow smear microscopy and PCR assay. RESULTS The patient had typical clinical symptoms of leishmaniasis, including irregular fever, hepatosplenomeg- aly, low serum albumin and elevated globulin. Bone marrow smear microscopy identified L. donovani amastigotes, and both rK39 strip test and PCR assay were positive, while the case was tested negative for SARS-CoV-2. COVID-19 was therefore excluded and visceral leishmaniasis was diagnosed. Standard full-dose treatment with sodium stibogluconate was given, and no Leishmania was found on blood smears during the reexamination. No recurrence was found during the followup after discharge for hospital. CONCLUSIONS During the COVID-19 pandemic, it is recommended to increase the perception of differential diagnosis of visceral leishmaniasis among first-contact doctors, and reinforce the capability of differential diagnosis and health education of visceral leishmaniasis among medical and healthcare institutions at all levels, to prevent missed diagnosis and misdiagnosis of visceral leishmaniasis.

Abstract
UNLABELLED The relationship between pulmonary function (PF) and bone mineral density (BMD) remains controversial. In the US population, we found a positive association between PF and BMD. Mixed variables such as age, gender, and race may influence this association. INTRODUCTION Based on the data from the National Health and Nutrition Examination Survey (NHANES) from 2007 to 2010, this study explored whether there is a correlation between PF (1st second forceful expiratory volume as a percentage of expected value (FEV1(% predicted)), (one-second rate (FEV1/FVC)), and bone mineral density. METHODS We evaluated the relationship between PF and BMD in 6327 NHANES subjects (mean age 44.51 ± 15.64 years) from 2007 to 2010. The bone mineral density of the whole femur was measured by dual-energy X-ray absorptiometry (DXA). After adjusting for a wide range of confounders, we examined the relationship between PF and total femur BMD using a multiple linear regression model. RESULTS Correction of race, age, alcohol consumption, body mass index (BMI), height, poor income ratio (PIR), total protein, serum calcium, serum uric acid, cholesterol, serum phosphorus, blood urea nitrogen, FEV1(% predicted), and femur BMD were positively correlated (β = 0.032, 95% CI: 0.010-0.054, P = 0.004). FEV1/FVC was positively correlated with spine BMD (β = 0.275 95%CI: 0.102-0.448, P = 0.002). CONCLUSIONS Our study shows that PF is positively associated with BMD in the US population. A variety of factors such as race and age influence this relationship. the relationship between PF and BMD needs to be further investigated, including specific regulatory mechanisms and confounding factors.

Abstract
BACKGROUND It was demonstrated that external stress, such as in vitro maturation (IVM) and vitrification process can induce significantly reduced development capacity in oocytes. Previous studies indicated that antioxidants play a pivotal part in the acquisition of adaptation in changed conditions. At present, the role of the natural potent antioxidant PCB2 in response to IVM and vitrification during ovine oocyte manipulation has not been explored. OBJECTIVE To investigate whether PCB2 treatment could improve the developmental potential of ovine oocytes under IVM and vitrification stimuli. MATERIALS AND METHODS The experiment was divided into two parts. Firstly, the effect of PCB2 on the development of oocytes during IVM was evaluated. Un-supplemented and 5 ug per mL PCB2-supplemented in the IVM solution were considered as control and experimental groups (C + 5 ug per mL PCB2). The polar body extrusion (PBE) rate, mitochondrial membrane potential (MMP), ATP, reactive oxygen species (ROS) levels and early apoptosis of oocytes were measured after IVM. Secondly, we further determine whether PCB2 could improve oocyte quality under vitrification stress. The survival rate, PBE rate and early apoptosis of oocytes were compared between fresh group, vitrified group and 5 ug per mL PCB2-supplemented in the IVM solution after vitrification (V + 5 ug per mL PCB2). RESULTS Compared to the control group, adding PCB2 significantly increased PBE rate (79.4% vs. 62.8%, P < 0.01) and MMP level (1.9 +/- 0.08 vs. 1.3 +/- 0.04, P < 0.01), and decreased ROS level (47.1 +/- 6.3 vs. 145.3 +/- 8.9, P < 0.01). However, there was no significant difference in ATP content and early apoptosis. Compared to the fresh group, vitrification significantly reduced oocytes viability (43.0% vs. 90.8%, P < 0.01) as well as PBE rate (24.2% vs. 60.6%, P < 0.05). However, 5 ug per mL PCB2-supplemention during maturation had no effect on survival, PBE or early apoptosis in vitrified oocytes. CONCLUSION PCB2 could effectively antagonise the oxidative stress during IVM and promote oocyte development. DOI: 10.54680/fr23210110412.

Abstract
AIM To test the feasibility of ultra-low-dose (ULD) computed tomography (CT) combined with an artificial intelligence iterative reconstruction (AIIR) algorithm for screening pulmonary nodules using computer-assisted diagnosis (CAD). MATERIALS AND METHODS A chest phantom with artificial pulmonary nodules was first scanned using the routine protocol and the ULD protocol (3.28 versus 0.18 mSv) to compare the image quality and to test the acceptability of the ULD CT protocol. Next, 147 lung-screening patients were enrolled prospectively, undergoing an additional ULD CT immediately after their routine CT examination for clinical validation. Images were reconstructed with filtered back-projection (FBP), hybrid iterative reconstruction (HIR), the AIIR, and were imported to the CAD software for preliminary nodule detection. Subjective image quality on the phantom was scored using a five-point scale and compared using the Mann-Whitney U-test. Nodule detection using CAD was evaluated for ULD HIR and AIIR images using the routine dose image as reference. RESULTS Higher image quality was scored for AIIR than for FBP and HIR at ULD (p<0.001). As reported by CAD, 107 patients were presented with more than five nodules on routine dose images and were chosen to represent the challenging cases at an early stage of pulmonary disease. Among such, the performance of nodule detection by CAD on ULD HIR and AIIR images was 75.2% and 92.2% of the routine dose image, respectively. CONCLUSION Combined with AIIR, it was feasible to use an ULD CT protocol with 95% dose reduction for CAD-based screening of pulmonary nodules.

Abstract
Purpose To advance the development of radiomic models of bone quality using the recently introduced Ultra-High Resolution CT (UHR CT), we investigate inter-scan reproducibility of trabecular bone texture features to spatially-variant azimuthal and radial blurs associated with focal spot elongation and gantry rotation. Methods The UHR CT system features 250×250 μm detector pixels and an x-ray source with a 0.4×0.5 mm focal spot. Visualization of details down to ~150 μm has been reported for this device. A cadaveric femur was imaged on UHR CT at three radial locations within the field-of-view: 0 cm (isocenter), 9 cm from the isocenter, and 18 cm from the isocenter; we expect the non-stationary blurs to worsen with increasing radial displacement. Gray level cooccurrence (GLCM) and gray level run length (GLRLM) texture features were extracted from 237 trabecular regions of interest (ROIs, 5 cm diameter) placed at corresponding locations in the femoral head in scans obtained at the different shifts. We evaluated concordance correlation coefficient (CCC) between texture features at 0 cm (reference) and at 9 cm and 18 cm. We also investigated whether the spatially-variant blurs affect K-means clustering of trabecular bone ROIs based on their texture features. Results The average CCCs (against the 0 cm reference) for GLCM and GLRM features were ~0.7 at 9 cm. At 18 cm, the average CCCs were reduced to ~0.17 for GLCM and ~0.26 for GLRM. The non-stationary blurs are incorporated in radiomic features of cancellous bone, leading to inconsistencies in clustering of trabecular ROIs between different radial locations: an intersection-over-union overlap of corresponding (most similar) clusters between 0 cm and 9 cm shift was >70%, but dropped to <60% for the majority of corresponding clusters between 0 cm and 18 cm shift. Conclusion Non-stationary CT system blurs reduce inter-scan reproducibility of texture features of trabecular bone in UHR CT, especially for locations >15 cm from the isocenter. Radiomic models of bone quality derived from UHR CT measurements at isocenter might need to be revised before application in peripheral body sites such as the hips.

Abstract
INTRODUCTION Sciatica is a pain disorder often caused by the herniated disk compressing the lumbosacral nerve roots. Neuroimaging studies have identified functional abnormalities in patients with chronic sciatica (CS). However, few studies have investigated the neural marker of CS using brain structure and the classification value of multidimensional neuroimaging features in CS patients is unclear. METHODS Here, structural and resting-state functional magnetic resonance imaging (fMRI) was acquired for 34 CS patients and 36 matched healthy controls (HCs). We analyzed cortical surface area, cortical thickness, amplitude of low-frequency fluctuation (ALFF), regional homogeneity (REHO), between-regions functional connectivity (FC), and assessed the correlation between neuroimaging measures and clinical scores. Finally, the multimodal neuroimaging features were used to differentiate the CS patients and HC individuals by support vector machine (SVM) algorithm. RESULTS Compared to HC, CS patients had a larger cortical surface area in the right banks of the superior temporal sulcus and rostral anterior cingulate; higher ALFF value in the left inferior frontal gyrus; enhanced FCs between somatomotor and ventral attention network. Three FCs values were associated with clinical pain scores. Furthermore, the three multimodal neuroimaging features with significant differences between groups and the SVM algorithm could classify CS patients and HC with an accuracy of 90.00%. DISCUSSION Together, our findings revealed extensive reorganization of local functional properties, surface area, and network metrics in CS patients. The success of patient identification highlights the potential of using artificial intelligence and multimodal neuroimaging markers in chronic pain research.

Abstract
BACKGROUND Developmental stage and cryopreservation method have significant impact on the pregnancy rate after transfer of embryos produced in vivo. OBJECTIVE To determine the pregnancy outcomes from ovine embryos cryopreserved at different developmental stages. MATERIALS AND METHODS Embryos at different developmental stages were obtained from donor ewes through simultaneous estrus treatment and laparoscopic artificial insemination. Embryos, either cryopreserved via vitrification or slow freezing method, were implanted into recipient ewes. The pregnancy rate was determined 35 days after transfer. RESULTS The pregnancy rate of developing embryos increases after transfer from the morula stage, early blastocyst to expanded blastocyst stages (64.9%, 73.9% and 81.3%, respectively). However, cryopreservation significantly decreases the pregnancy rate of embryos at all three developmental stages, and there is no significant difference among developmental stages (43.9%, 43.7%, 52.9%, respectively). There is also no significant difference in the pregnancy rate between slowly-frozen embryos and vitrified embryos. CONCLUSION The pregnancy outcomes of embryo transfer is better at the expanded blastocyst stage than at earlier stages. However, no difference is observed in the pregnancy rate of embryos at different developmental stage after cryopreservation, either by slow freezing and vitrification. Cryopreservation methods for ovine embryos, both slow freezing and vitrification, need further improvement. doi.org/10.54680/fr22510110512.

Abstract
Background The association between the serum uric acid (sUA) to creatinine ratio (sUA/Cr) and non‐alcoholic fatty liver disease (NAFLD) has not been sufficiently clarified. In this study, we investigated the relationship between sUA/Cr and NAFLD among participants in the United States. Methods We performed a cross‐sectional study based on data from the National Health and Nutrition examination Survey (NHANES) 2017–2018. A measured controlled attenuation parameter (CAP) value of ≥274 dB/m detected by Fibroscan was used to identify hepatic steatosis. SUA/Cr was calculated as sUA divided by serum creatinine. Multivariate logistic regression analysis was used to estimate the association between sUA/Cr and NAFLD. The adjusted odds ratio (OR) of sUA/Cr for NAFLD was estimated, and subgroup analysis stratified by sex was also conducted. The nonlinear relationship between sUA/Cr and NAFLD was further described using smooth curve fittings and threshold‐effect analysis. Results We found that sUA/Cr was positively correlated with NAFLD status after fully adjustment for confounding factors. In subgroup analysis stratified by sex, the positive interaction between sUA/Cr and NAFLD status only existed in women but not in men. Moreover, the nonlinear association between sUA/Cr and NAFLD status was an inverted U‐shaped curve with an inflection point at 9.7 among men. Conclusions Our study identified that sUA/Cr was positively associated with the risk of NAFLD among individuals in the United States. Moreover, the correlation between sUA/Cr and NAFLD differed according to sex.

Abstract
BackgroundCT-P13 is an approved biosimilar to EU-approved and US-licensed Infliximab (INX) for the indications of rheumatoid arthritis (RA), adult and paediatric Crohn’s disease, adult and paediatric ulcerative colitis, ankylosing spondylitis, psoriatic arthritis and psoriasis.ObjectivesThe purpose of this study was to demonstrate equivalence of efficacy and compare PK and safety profiles of CT-P13 and China-approved INX.MethodsIn this randomized, double blinded, multicenter, parallel-group, phase III study, patients with active RA who had been responding inadequately to methotrexate for at least 3 months, were randomized to receive either CT-P13 or China-approved INX. Patients were treated with doses of 3 mg/kg at Weeks 0, 2, 6, then every 8 weeks up to Week 54. Prior to dosing at Week 30, patients randomized to China-approved INX underwent a second randomization either to continue China-approved INX or to switch to CT-P13 at Week 30. Results of patients who underwent transition to CT-P13 were included in the China-approved INX group. The primary efficacy endpoint was change in DAS28 (CRP) from baseline to Week 14, which was analyzed using an analysis of covariance. Equivalence was determined if the 90% CI for the estimate of treatment difference was entirely contained within the predefined equivalence margin of -0.6 to 0.6.Results270 patients were randomly assigned to 2 treatment groups in a 1:1 ratio (136 and 134 patients in the CT-P13 and China-approved INX groups, respectively) and 184 patients completed the study. The least square mean change (standard error) of DAS28 (CRP) from baseline to Week 14, -1.566 [0.1419] and -1.547 [0.1491], was similar between the CT-P13 and China-approved INX groups, respectively. The 90% CI for the estimate of treatment difference (-0.29, 0.25) was contained within the predefined equivalence margin, which demonstrated therapeutic equivalence between the groups. The mean actual values for DAS28 (CRP) decreased from baseline to Week 54 and were similar between the groups (Figure 1). Additional efficacy endpoints, including ACR responses (ACR20 at Week 14; 60.6%, 54.8% and at Week 54; 65.1%, 60.6% in the CT-P13 and China-approved INX groups, respectively), EULAR responses, CDAI, and SDAI, were similar between the groups, even after switching at Week 30. During the study, mean serum INX concentrations were similar between the groups. Between Weeks 14 and 22, mean (percent coefficient of variation) AUCτ were 11156333.615 (44.796) ng·h/mL and 11462884.280 (51.057) ng·h/mL, and Cmax,ss were 66577.2 (31.4) ng/mL and 66356.1 (21.0) ng/mL in the CT-P13 and China-approved INX groups, respectively, which were similar between the groups. Most treatment-emergent AEs were grade 1 or 2 in intensity. One malignancy was reported in the CT-P13 group and no deaths were reported. The proportions of patients with anti-drug antibodies were similar between the groups, even after switching at Week 30. The overall safety profile of CT-P13 was comparable to that of China-approved INX and no new safety issues were observed (Table 1).Table 1.Summary of Safety ResultsNumber of patients (%)CT-P13 (N=136)China-approved Infliximab (N=133)Treatment-emergent AEsTotal115 (84.6%)107 (80.5%)Related97 (71.3%)86 (64.7%)Treatment-emergent serious AEsTotal17 (12.5%)12 (9.0%)Related10 (7.4%)6 (4.5%)Infusion related reaction/ hypersensitivity/anaphylactic reactionsTotal(=Related)20 (14.7%)19 (14.3%)InfectionsTotal45 (33.1%)43 (32.3%)Related36 (26.5%)40 (30.1%)Note: Summary is presented for the safety population who received at least 1 dose (full or partial) of study drug.ConclusionThe study demonstrated that efficacy of CT-P13 is equivalent to that of China-approved INX.

Abstract
INTRODUCTION Postoperative ileus (POI) is an inevitable complication of almost all abdominal surgeries, which results in prolonged hospitalisation and increased healthcare costs. Various treatment strategies have been developed for POI but with limited success. Electroacupuncture (EA) might be a potential therapy for POI. However, evidence from rigorous trials that evaluated the effectiveness of EA for POI is limited. Thus, the aim of this study was to examine whether EA can safely reduce the time to the first defecation after laparoscopic surgery in patients with POI. METHODS AND ANALYSIS This multicentre randomised sham-controlled trial will be conducted in four hospitals in China. A total of 248 eligible participants with colorectal cancer who will undergo laparoscopic surgery will be randomly allocated to an EA group and a sham EA group in a 1:1 ratio. Treatment will be performed starting on postoperative day 1 and continued for four consecutive days, once per day. If the participant is discharged within 4 days after surgery, the treatment will cease on the day of discharge. The primary outcome will be the time to first defecation. The secondary outcome measures will include time to first flatus, tolerability of semiliquid and solid food, length of postoperative hospital stay, postoperative nausea and vomiting, abdominal distension, postoperative pain, postoperative analgesic, time to first ambulation, blinding assessment, credibility and expectancy and readmission rate. ETHICS AND DISSEMINATION Ethics approval was obtained from the Ethics Committee of Beijing University of Chinese Medicine (number 2020BZHYLL0116) and the institutional review board of each hospital. The results will be disseminated through peer-reviewed publications. This study protocol (V.3.0, 6 March 2020) involves human participants and was approved by the ethics committees of Beijing University of Chinese Medicine (number 2020BZHYLL0116), Beijing Friendship Hospital Affiliated to Capital Medical University (number 2020-P2-069-01), Beijing Chao-Yang Hospital Affiliated to Capital Medical University (number 2020-3-11-2), National Cancer Center/National Clinical Research Center for Cancer/Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College (number 20/163-2359), and the Affiliated Hospital of Qingdao University (number QYFYKYLL711311920). The participants gave informed consent to participate in the study before taking part. TRIAL REGISTRATION NUMBER ChiCTR2000038444.

Abstract
Objective The purpose of this study was to explore the structural and functional asymmetry of precentral and postcentral gyrus in patients with unilateral chronic shoulder pain (CSP) utilizing MRI. Patients and Methods We collected structural and resting-state functional MRI (rs-fMRI) data in 22 left-sided, 15 patients with right-sided CSP, and 24 healthy controls (HCs). Here, we performed the structural asymmetry and seed-based functional connectivity (FC) analyses. We extracted regional cortical thickness and surface area measurements from T1-weighted MRI images, using asymmetry indexes (AIs) to assess asymmetries. We used Data Processing and Analysis for Brain Imaging software for seed-based FC analysis and selected unilateral-precentral and postcentral as the regions of interest. Then, we performed group comparisons of the neuroimaging metrics, and also explored the relationships between brain asymmetry and clinical variables. Results We found significant differences in surface area AIs of the precentral among three groups, the AI values were negatively correlated with the visual analog scale score and positively correlated with Constant–Murley scores (CMS) in the left-sided CSP group. Further, FC of left postcentral with cingulate gyrus and left paracentral lobule showed significant group differences; FC of right postcentral with left caudate, left paracentral, and left postcentral were different among groups; FC of right precentral with the cingulate gyrus, precuneus, and left paracentral revealed significant group differences. Besides, there was a positive correlation between right precentral-cingulate gyrus FC and CMS in the right-sided CSP group. Conclusion Surface area and FC patterns asymmetry exist in precentral and postcentral gyrus in patients with unilateral CSP. Asymmetry trend is associated with pain severity and shoulder joint function impairment. Brain structural and functional asymmetry may be an important indicator for understanding the potential mechanism of chronic pain.

Abstract
Bone marrow mesenchymal stem cells (BMSCs) have self-renewal potential. Sirt1 regulates cell differentiation and apoptosis. However, Sirt1’s effect on BMSCs osteogenic/adipogenic differentiation has not been fully elucidated. SD rats were randomly divided into Osteoporosis (OP)
group and sham operation group. OP rat BMSCs were isolated and assigned into control group, NC group and Sirt1 siRNA group followed by analysis of Sirt1 level by Real-time PCR, cell proliferation by MTT assay, expression of OC, OPN and FABP4 level by real time PCR, and β-Catenin/TCF1/Runx2
protein expression by Western blot. In OP group, Sirt1 expression was significantly increased and BMSCs proliferation was decreased along with reduced OC and OPN mRNA expression, increased FABP4 expression and reduced β-Catenin/TCF1/Runx2 expression compared with sham operation
group (P < 0.05). In Sirt1 siRNA group, Sirt1 expression was significantly reduced, BMSCs proliferation was increased, OC and OPN mRNA expression was increased, FABP4 expression was decreased, and β-Catenin/TCF1/Runx2 expression was increased compared to OP group (P
< 0.05). Sirt1 is increased in osteoporosis. Down-regulating Sirt1 in osteoporotic BMSCs can regulate β-Catenin/TCF1/Runx2 signaling and promote BMSCs osteogenic differentiation and inhibit adipogenic differentiation.

Abstract
Porcine vertebral and teat numbers are variable and important economic traits in pig production. However, the quantitative trait loci (QTL) and candidate genes for both of these traits in the Beijing Black Pig are not yet known. In the present study, number of vertebrae and number of teats were obtained for 891 individuals of the Beijing Black Pig and genotyped using the Illumina Porcine 50 K BeadChip. Genome scanning was performed to detect associated variants and candidate genes for both traits using a genome-wide association study by tassel software. For vertebral number, 15 significant SNPs were located on SSC7. According to linkage disequilibrium analysis on SSC7, a haplotype block of 221 kb from 97.4 to 97.6 Mb was shown to contain a good candidate gene ABCD4. Interestingly, on SSC12, we recorded a novel QTL containing three significant SNPs and 34 annotated genes from 24.0 to 25.7 Mb for vertebral number. Of the 34 genes, nine Hox family genes (HOXB 1-7, 9, and 13) were found to be good candidate genes. Using the 34 genes, a gene ontology analysis was performed to detect enrichment of anterior/posterior pattern specification. For teat number, a novel chromosome-wide significant QTL was identified on SSC10. In this QTL region, one significant SNP was identified. The nearest gene, NTRK2, was regarded as a candidate gene. The present results expanded the QTL for vertebral and teat numbers and provided useful molecular markers for breeding in the Beijing Black Pig population.

Abstract
Background:Rheumatoid arthritis (RA) is a chronic, inflammatory synovitis based systemic disease of unknown etiology1. The genes and pathways in the inflamed synovium of RA patients are poorly understood.Objectives:This study aims to identify differentially expressed genes (DEGs) associated with the progression of synovitis in RA using bioinformatics analysis and explore its pathogenesis2.Methods:RA expression profile microarray data GSE89408 were acquired from the public gene chip database (GEO), including 152 synovial tissue samples from RA and 28 healthy synovial tissue samples. The DEGs of RA synovial tissues were screened by adopting the R software. The Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were performed. Protein-protein interaction (PPI) networks were assembled with Cytoscape software.Results:A total of 654 DEGs (268 up-regulated genes and 386 down-regulated genes) were obtained by the differential analysis. The GO enrichment results showed that the up-regulated genes were significantly enriched in the biological processes of myeloid leukocyte activation, cellular response to interferon-gamma and immune response-regulating signaling pathway, and the down-regulated genes were significantly enriched in the biological processes of extracellular matrix, retinoid metabolic process and regulation of lipid metabolic process. The KEGG annotation showed the up-regulated genes mainly participated in the staphylococcus aureus infection, chemokine signaling pathway, lysosome signaling pathway and the down-regulated genes mainly participated in the PPAR signaling pathway, AMPK signaling pathway, ECM-receptor interaction and so on. The 9 hub genes (PTPRC, TLR2, tyrobp, CTSS, CCL2, CCR5, B2M, fcgr1a and PPBP) were obtained based on the String database model by using the Cytoscape software and cytoHubba plugin3.Conclusion:The findings identified the molecular mechanisms and the key hub genes of pathogenesis and progression of RA.References:[1]Xiong Y, Mi BB, Liu MF, et al.

Abstract
Background:Psoriasis is an immune-mediated, genetic disease manifesting in the skin or joints or both, and also has a strong genetic predisposition and autoimmune pathogenic traits1. The hallmark of psoriasis is sustained inflammation that leads to uncontrolled keratinocyte proliferation and dysfunctional differentiation. And it’s also a chronic relapsing disease, which often necessitates a long-term therapy2.Objectives:To investigate the molecular mechanisms of psoriasis and find the potential gene targets for diagnosis and treating psoriasis.Methods:Total 334 gene expression data of patients with psoriasis research (GSE13355 GSE14905 and GSE30999) were obtained from the Gene Expression Omnibus database. After data preprocessing and screening of differentially expressed genes (DEGs) by R software. Online toll Metascape3 was used to analyze Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis of DEGs. Interactions of proteins encoded by DEGs were discovered by Protein-protein interaction network (PPI) using STRING online software. Cytoscape software was utilized to visualize PPI and the degree of each DEGs was obtained by analyzing the topological structure of the PPI network.Results:A total of 611 DEGs were found to be differentially expressed in psoriasis. GO analysis revealed that up-regulated DEGs were mostly associated with defense and response to external stimulus while down-regulated DEGs were mostly associated with metabolism and synthesis of lipids. KEGG enrichment analysis suggested they were mainly enriched in IL-17 signaling, Toll-like receptor signaling and PPAR signaling pathways, Cytokine-cytokine receptor interaction and lipid metabolism. In addition, top 9 key genes (CXCL10, OASL, IFIT1, IFIT3, RSAD2, MX1, OAS1, IFI44 and OAS2) were identified through Cytoscape.Conclusion:DEGs of psoriasis may play an essential role in disease development and may be potential pathogeneses of psoriasis.References:[1]Boehncke WH, Schon MP.

Abstract
Background:Gastrointestinal microbiota, particularly gut microbiota is an indispensable environmental factor in the progression of Rheumatoid Arthritis (RA). Understanding the diversity and function of the intestinal flora in patients with RA is part and parcel to understand the relationship between microbiota and human health.Objectives:This study aimed to identify the diversity and function of the intestinal flora in patients with RA.Methods:A total of 166 participants were recruited in this study, comprising 93 RA patients and 73 age and sex-matched healthy controls (HCs). Microbial genome was extracted from approximately 250mg fresh fecal samples from all participants using QIAamp PowerFecal DNA Kit (Qiagen). The V3-V4 variable regions of bacterial 16S rRNA genes were sequenced with the Illumina Miseq PE300 system. Sequence data were compiled and processed using Qiime2. Sequences were grouped into operational taxonomic units (ASVs)1. Microbial diversity was estimated by the Simpson index. PICRUSt2 was used to predict KEGG functional pathway differences between RA and HC intestinal flora functions based on ASV Tables2. Linear Discriminant Analysis (LDA) Effect Size (LEfSe) analysis was performed using LEfSe software to discovery the different intestinal flora and functions between RA and healthy.Results:The alpha-diversity index of Simpson the microbiome in RA patients was lower than that of HCs (Figure 1a, P <0.05). Compared with HCs, bacterial Bacilli and Lactobacillales were more abundant in patients with RA (Figure 1b, P <0.05). In contrast, Marinifilaceae, Peptococcaceae, Peptococcales and Phascolarcto bacterium were less abundant in the RA group (Figure 1b, P <0.05). As shown in Figure 1c, propanoate metabolism, taurine and hypotaurine metabolism, ascorbate and aldarate metabolism, biosynthesis of siderophore group nonribosomal peptides and glutathione metabolism were the most significantly altered pathways in RA (P <0.05). Epithelial cell signaling in Helicobacter pylori infection, RNA transport, RNA degradation and plant-pathogen interaction were the most significantly altered pathways in HC (P <0.05). The different KEGG metabolic pathways were mainly concentrated in carbohydrate and amino acid metabolism.Conclusion:Gut dysbiosis in RA patients mainly characterized by reduced the diversity and impaired abundance of the intestinal flora, which severely influence the metabolism of gastrointestinal microbiota. The discovery of the associated intestinal microbiota of RA may provide a new idea for RA treatment.References:[1]Han L, Zhao K, Li Y, et al.

Abstract
Inflammation is a critical player in the development and progression of colon cancer. Basic leucine zipper transcription factor ATF-like 3 (BATF3) plays an important role in infection and tumor immunity through regulating the development of conventional type 1 dendritic cells (cDC1s). However, the function of BATF3 in colitis and colitis-associated colon cancer (CAC) remains unclear. Here, BATF3 wild-type and knockout mice were used to construct an AOM/DSS-induced CAC model. In addition, DSS-induced chronic colitis, bone marrow cross-transfusion (BMT), neutrophil knockout, and other animal models were used for in-depth research. We found that BATF3 deficiency in intestinal epithelial cells rather than in cDC1s inhibited CAC, which was depended on inflammatory stimulation. Mechanistically, BATF3 directly promoted transcription of CXCL5 by forming a heterodimer with JunD, and accelerated the recruitment of neutrophils through the CXCL5-CXCR2 axis, ultimately increasing the occurrence and development of CAC. Tissue microarray and TCGA data also indicated that high expression of BATF3 was positively correlated with poor prognosis of colorectal cancer and other inflammation-related tumors. In summary, our results demonstrate that intestinal epithelial-derived BATF3 relies on inflammatory stimulation to promote CAC, and BATF3 is expected to be a novel diagnostic indicator for colitis and CAC.

Abstract
Objective To investigate the effects of Helicobacter pylori(H.pylori)infection on autonomic nervous function and calcitonin gene-related peptide in patients with functional dyspepsia(FD). Methods Thirty-one patients with FD matching Rome Ⅳ criteria were included and divided into H.pylori-positive group and H.pylori-negative group.All patients were evaluated by Symptom Index of Dyspepsia(SID),Nepean Dyspepsia Index(NDI),and Hospital Anxiety and Depression Scale(HADS).Their heart rate variability(HRV)and calcitonin gene-related peptide(CGRP)level were also measured. Results There were no significant differences in SID(Z=-0.858, P=0.858),NDI(Z=-1.464, P=0.143),and Hospital Depression Scale score(Z=0.699, P=0.485).However,the Hospital Anxiety Scale score was significantly higher in H.pylori-positive group than the H.pylori-negative group(Z=-2.470, P=0.014).The level of CGRP in H.pylori-positive group[(0.999±0.274)ng/ml]was significantly higher than that in the H.pylori-negative group[(0.812±0.172)ng/ml;t=2.238, P=0.033].HRV data showed no significant difference between these two groups at very low frequency(t=-1.210, P=0.236),low frequency(LF)(t=0.419, P=0.678),high frequency(HF)(t=0.612, P=0.546),LF/HF(t=-0.882, P=0.399),and total power(t=-0.963, P=0.344). Conclusion In FD patients,patients with H.pylori-positive FD patients have higher depression and CGRP levels than those without H.pylori infection,although their dyspepsia symptoms and HRV show no notable changes.

Abstract
PURPOSE To evaluate the performance of a novel ultra-high resolution multi-detector CT scanner (Canon Aquilion Precision UHR CT), capable of visualizing ~150 μm details, in quantitative assessment of bone microarchitecture. Compared to conventional CT, the spatial resolution of UHR CT begins to approach the size of the trabeculae. This might enable measurements of microstructural correlates of osteoporosis, osteoarthritis, and other bone disease. METHODS The UHR CT system features a 160-row x-ray detector with 250×250 μm pixels (measured at isocenter) and a custom-designed x-ray source with a 0.4×0.5 mm focal spot. Visualization of high contrast details down to ~150 μm has been achieved on this device, which is now commercially available for clinical use. To evaluate the performance of UHR CT in quantification of bone microstructure, we imaged a variety of human bone samples (including ulna, radius, and vertebrae) embedded in a ~16 cm diameter plastic cylinder and in an anthropomorphic thorax phantom (QRM-Thorax, QRM Gmbh). Helical UHR CT acquisitions (120 kVp tube voltage) were acquired at scan exposures of 375 mAs - 5 mAs. For comparison, the samples were also imaged using a Normal Resolution (NR) mode available on the scanner, involving 500 μm slice thickness, exposure of 50 mAs, and a focal spot of 0.6×1.3 mm. We obtained micro-CT (μCT) of the bone samples at ~28 μm voxel size as a gold-standard reference. Geometric measurements of bone microstructure were performed in 17 regions-of-interests (ROIs) distributed throughout the bones of the phantoms; image registration was used to place the ROIs at corresponding locations in the UHR CT and NR CT. Trabecular thickness Tb.Th, spacing Tb.Sp, and Bone Volume fraction BvTv were obtained. The UHR and NR imaging protocols were compared terms of correlations to μCT and error of trabecular measurements. The effect of dose on trabecular morphometry was also studied for the UHR CT. Furthermore, we evaluated the sensitivity of texture features of trabecular bone (recently proposed as an alternative to geometric indices of microstructure) to imaging protocol. Image texture evaluation was performed using ~150 regions of interest (ROIs) across all bone samples. Three-dimensional Gray Level Co-occurrence Matrix (GLCM) and Gray Level Run Length Matrix (GLRM) features were extracted for each ROI. We analyzed correlation and concordance correlation coefficient (CCC) of the mean ROI values of texture features obtained using the UHR and NR modes. RESULTS UHR CT reconstructions of bone samples clearly demonstrated improved visualization of the trabeculae compared to NR CT. UHR CT achieved substantially better correlations for all three metrics of bone microstructure, in particular for BvTv (correlation coefficient of 0.91 for UHR CT compared to 0.84 for NR CT) and TbSp (correlation of 0.74 for UHR CT and 0.047 for NR CT). The error obtained with UHR CT was generally smaller than that of NR CT. For TbSp, the mean deviation from μCT (averaged across all bone samples) was only ~0.07 for UHR CT, compared to 0.25 for NR CT. Analysis of reproducibility of texture features of trabecular bone between UHR CT and NR CT revealed fair correlations (>0.7) for the majority of GLCM features, but relatively poor CCC (e.g. 0.02 for Energy and 0.04 for Entropy). The magnitude of texture metrics is particularly affected by the enhanced spatial resolution of UHR CT. CONCLUSION The recently introduced UHR CT achieves improved correlation and reduced error in measurements of trabecular bone microstructure compared to conventional resolution CT. Future development of diagnostic strategies based on textural biomarkers derived from UHR CT will need to account for potential sensitivity of texture features to image resolution.

Abstract
FLOWERING LOCUS T (FT) is a key integrator of environmental signals and internal cues, and codes for florigen-like activity which regulates the transition from vegetative to reproductive growth in flowering plants. Unlike annual plants, perennial tree species undergo several years of vegetative growth prior to the transition to the reproductive stage, as characterised by the ability to form flower buds. Thereafter, trees in temperate regions typically display an annual growth cycle involving distinct vegetative growth, flowering and dormancy stages. In London plane (Platanus acerifolia Willd.), a FT-like gene has previously been identified. Here, we report the isolation of a novel FT orthologous gene, PaFTL, and investigate the functions of PaFT and PaFTL through the analysis of expression profiles and transgenic phenotypes. PaFT displayed the highest levels of expression during tree dormancy, and similarly elevated expression levels were seen under conditions of low temperature and short days (LT/SD). In contrast, PaFTL transcripts were up-regulated during the floral transition phase, the early stages of inflorescence development and throughout the main flowering period, whereas expression levels were low and variable during dormancy and in response to LT/SD treatments. Ectopic expression of 35s::PaFTL in tobacco produced a phenotype similar to that with PaFT, namely, advanced floral initiation. Overall, the results suggest that PaFT and PaFTL have both conserved and diverse functions in floral initiation, floral development and dormancy regulation.

Abstract
BACKGROUND Primary erythromelalgia (PE) is a dominant inherited disorder characterized by recurrent pain, redness, and warmth of the extremities that is caused by gain-of-function mutations in Nav1.7 encoding gene SCN9A. Most of the PE-causing mutations of Nav1.7 have been shown to be able to render Nav1.7-expressing cells hyperexcitable, however in most PE cases the symptoms are refractory to treatment with sodium channel blockers and the mechanism underlying the intractability has not been clearly clarified. OBJECTIVE To identify the mutation of SCN9A in a Chinese Han family with typical symptoms of PE and study the electrophysiological effect of the identified mutation. METHODS A Chinese Han family with typical symptoms of PE was collected and the proband's response to treatment was recorded. All the exons and flanking intronic sequences of SCN9A were amplified with PCR and sequenced. Several online programs were used to predict the damaging effect of variants. The functional effect of variants was studied by voltage-clamp analysis in CHO-K1 cells. RESULTS The PE symptoms of the proband are refractory to all kinds of reported medications. Sequence analysis of SCN9A showed that a novel c.2477T>A (p. F826Y) mutation co-segregated with the disease phenotype. Several online programs predicted that the F826Y mutation has a deleterious effect on the gene product. Voltage-clamp analysis showed that while compared with the wild-type channel, activation of the F826Y mutant channel was shifted by 7.7 mV in a hyperpolarizing direction, whereas steadystate inactivation was shifted by 4.3 mV in a depolarizing direction. CONCLUSION A novel disease-causing SCN9A Mutation (F826Y) was identified in a Chinese family with typical PE symptoms refractory to treatment. F826Y of Nav1.7 could render DRG neurons hyperexcitable, contributing to the pathogenesis of PE.

Abstract
Objective: To investigate the expression of tumor necrosis factor alpha-inducible protein 8 like-2 (TIPE2) and tissue factor (TF) in patients with bronchial asthma. And to explore the regulation of TIPE2 on TF. Methods: Sixty-five asthmatic patients and 40 healthy controls were selected from the First Affiliated Hospital of Zhengzhou University from July to November, 2017. The expression of TIPE2 and TF in peripheral blood mononuclear cells of asthmatic patients and healthy controls were detected by Western blot.The level of TF protein in plasma was detected by enzyme-linked immunosorbent assay. The changes of TIPE2 and TF mRNA expression in THP-1 cells stimulated by house dust mite extract were detected by real-time fluorescence quantitative PCR (RT-PCR). The recombinant adenovirus Adv-TIPE2 was constructed and transfected into THP-1 cells and the effect of over-expression TIPE2 on TF expression in THP-1 cells was detected by RT-PCR. Results: The relative level of TIPE2 protein in asthmatic patients and healthy controls was 0.025±0.010 and 0.087±0.070, while that of TF was 0.40±0.27 and 0.15±0.10, respectively. Compared with healthy controls, the levels of TIPE2 protein decreased and TF protein increased in asthmatic patients, the differences were statistically significant (t=-5.06, 9.04, P<0.05) . TIPE2 protein level was negatively correlated with TF protein level (r=-0.460 3, P<0.05). The house dust mite extract reduced the expression level of TIPE2 mRNA in THP-1 cells, but increased the level of TF mRNA expression. When the concentration was 1 μg/ml, the change of TIPE2 mRNA was the most obvious at 4 h (P<0.05). The recombinant adenovirus Adv-TIPE2 was successfully constructed. The level of TF mRNA expression in THP-1 cells over-expressing TIPE2 gene was reduced (P<0.05). Conclusion: TIPE2, a negative regulator of inflammation, has a negative control effect on TF, and may be involved in the hyper-coagulable state of bronchial asthma by regulating TF expression.

MEASUREMENTS Frailty was defined as the presence of ≥3 domains among five modified Fried's criteria (unintentional weight loss, low physical activity level, weakness (low grip strength), exhaustion, and slowness (slow gait speed)) and pre-frailty as the presence of 1-2 domains. RESULTS The prevalence of frailty and pre-frailty was 10.4% and 53.3%, respectively, in this elderly population. Elevated BNP (≥100 pg/mL) was significantly associated with pre-frailty (OR: 1.61, 95% CI: 1.13-2.29) and frailty (OR: 2.63, 95% CI: 1.61-4.32) after adjustment for covariates. In addition, elevated BNP was associated with low grip strength (OR: 2.00, 95% CI: 1.41-2.82) and low gait speed (OR: 1.62, 95% CI: 1.15-2.28) after adjustment for multiple covariates. Log BNP was inversely associated with grip strength (r= -0.265, p<0.001) and gait speed (r= -0.189, p<0.001). CONCLUSION Elevated plasma BNP was associated with increased risks of frailty, pre-frailty, and low levels of grip strength and gait speed in the elderly community people.

Abstract
Even though a large amount of researches showing the clinical effectiveness of acupuncture, there are the researches indicating the absent difference between acupuncture and sham-acupuncture (placebo), which provides the doubts on the specificity of acupuncture. It may be considered that acupuncture intervention is complica-ted and may produce unique non-specific effect, which results in the failure to evaluate effectively the acupuncture efficacy. The influential factors of the non-specific effect of acupuncture include the interaction between physician and patient, expectancy, physician authority, acupuncture treatment experiences, etc. It may be also relevant with the anticipated biological effect, Hawthorne effect, Pavlovian conditioned reflex, etc.

Abstract
Pure red cell aplasia (PRCA) develops as a result of erythroid precursors failing to reach maturity in the bone marrow, which eventually leads to anemia. Here we present a case of a 64-year-old Asian male with a medical history of colorectal adenocarcinoma who had been treated with 6 cycles of oxaliplatin and capecitabine four years ago. The patient was diagnosed with PRCA and T-cell large granular lymphocyte leukemia.

Abstract
Liver biopsy is not routinely performed in treated chronic hepatitis B. Liver stiffness measurement has been validated for noninvasive liver fibrosis assessment in pretreatment chronic hepatitis B but has not been assessed for fibrosis monitoring during antiviral therapy. Liver stiffness was systemically monitored by Fibroscan® every 6 months in a cohort of patients with hepatitis B receiving antiviral therapy and compared with liver biopsies at baseline and week 104. A total of 534 hepatitis B e antigen-positive treatment-naive patients receiving telbivudine-based therapy with qualified liver stiffness measurement at baseline and week 104 were analyzed, 164 of which had adequate paired liver biopsies. Liver stiffness decreased rapidly (-2.2 kPa/24 weeks) in parallel with alanine aminotransferase (ALT) from 8.6 (2.6-49.5) kPa at baseline to 6.1 (2.2-37.4) kPa at week 24. Interestingly, liver stiffness decreased slowly (-0.3 kPa/24 weeks) but continually from week 24 to week 104 (6.1 vs 5.3 kPa, P < .001) while ALT levels remained stable within the normal range. More importantly, liver stiffness declined significantly irrespective of baseline ALT levels and liver necroinflammation grades. From baseline to week 104, the proportion of patients with no or mild fibrosis (Ishak, 0-2) increased from 74.4% (122/164) to 93.9% (154/164). Multivariate analysis revealed that percentage decline of 52-week liver stiffness from baseline was independently associated with 104-week liver fibrosis regression (odds ratio, 3.742; P = .016). Early decline of 52-week liver stiffness from baseline may reflect the remission of both liver inflammation and fibrosis and was predictive of 104-week fibrosis regression in treated patients with chronic hepatitis B.

Abstract
This study was conducted to determine the mechanism by which di-2-ethylhexyl phthalate (DEHP) exposure influences lipid metabolism of juvenile yellow catfish Tachysurus fulvidraco. Fish were exposed to three DEHP concentrations (0, 0·1 and 0·5 mg l-1 DEHP) for 8 weeks. Fatty acid synthase (FAS) activity significantly decreased with increasing DEHP concentrations, the highest value was in the Tween control group, whereas the lowest activities of carnitine palmitoyltransferase (CPT) and lipoprotein lipase (LPL) were in this group. The messenger (m)RNA levels of 6-phospho-gluconate dehydrogenase (6PGD), FAS and acetyl-CoA carboxylase a (ACCa) significantly increased with increasing DEHP concentration, the highest values were in the 0·5 mg l-1 DEHP group. The mRNA level of peroxisome proliferator-activated receptor γ (PPARγ) was lower in Tween control than in fish exposed to 0·1 and 0·5 mg l-1 DEHP. The highest mRNA level of ACCb was in the 0·1 mg l-1 DEHP group. These results indicate that DEHP exposure can disturb lipid metabolism at the enzymatic and mRNA levels in Pelteobagrus fulvidraco.

Abstract
A novel antioxidant, butylated caffeic acid (BCA) was rationally designed by adding a tert-butyl group to caffeic acid, which was synthesized at a high yield (36.2%) from 2-methoxy-4-methylphenol by a four-step reaction including Friedel-Crafts alkylation, bromine oxidation, ether bond hydrolysis and Knoevenagel condensation. Its antioxidant capacity was much stronger than common commercial antioxidant tert-butyl hydroquinone (TBHQ) and its mother compound, caffeic acid, in both rancimat and deep frying tests. When investigated via the DPPH method, the antioxidant capacity of BCA was almost equal to TBHQ, but lower than caffeic acid. BCA could be a potentially strong antioxidant, especially for food processing at high temperatures such as deep frying and baking.

Abstract
NADPH Oxidase-Dependent Oxidative Stress and Redox-Sensitive MAPKs Contribute to The Mechanisms of Acupuncture in Rostral Ventrolateral Medulla of Spontaneously Hypertensive Rats.
Oxidative stress in the rostral ventrolateral medulla (RVLM), where the sympathetic nervous control center is located, contributes to neural mechanisms of hypertension. Acupuncture was previously reported to favorably affect high blood pressure. However, little is known about the effect of acupuncture on oxidative stress-modulated mechanisms in hypertension. This study was designed to evaluate the hypothesis that acupuncture exerts an antihypertensive effect via ameliorating oxidative stress and the redox-sensitive pathway in the RVLM of spontaneously hypertensive rats (SHRs). Two weeks of acupuncture reduced blood pressure and sympathetic nervous system activity in SHRs. Oxidative stress in the RVLM was alleviated by acupuncture, accompanied by a decrease in NADPH oxidase activity and expression of its subunits. Acupuncture significantly altered the mitogen-activated protein kinases (MAPKs) signaling pathway as assessed by pathway enrichment analysis in a gene chip assay. The phosphorylation of p38MAPK, extracellular signal-regulated protein kinase (ERK)1/2, but not Jun N-terminal kinase (JNK), were downregulated by acupuncture. Microinjection bilaterally of the superoxide dismutase mimetic tempol, NADPH oxidase inhibitor apocynin or diphenyleneiodonium chloride into the RVLM mimicked the antihypertensive effect of acupuncture. In contrast, the NADPH oxidase agonist TBCA abolished the beneficial effects of acupuncture. Furthermore, injection of capsaicin, or surgical sectioning of the sciatic nerve abolished the antihypertensive effect of acupuncture. We conclude that acupuncture decreases NADPH oxidase derived ROS and inactivates its downstream MAPKs in the RVLM to restore sympathetic vasomotor activity and decrease blood pressure. The neural transmission from the sensory sciatic nerve is involved in mechanism of acupuncture in treating hypertension.

Abstract
Rhegmatogenous retinal detachment is a vision-threatening disease and is treated by either scleral buckling or pars planar vitrectomy. Rapid absorption of the subretinal fluid (SRF) helps in the early recovery of the vision. The absorption of SRF after the scleral buckling procedure is rapid, provided that the retinal break or breaks are closed at or after surgery. However, in some patients with rhegmatogenous retinal detachment, complete absorption of the SRF occur several weeks or months after the surgery. In this review, we discuss the factors influencing the rate of SRF absorption and the role of delayed absorption on visual recovery. We also discuss the therapeutic options for delayed SRF absorption and the available additional therapeutic options. Knowledge of the factors that influence the rate of SRF absorption, would enable the surgeon to predict the outcomes more accurately.

Abstract
OBJECTIVE To discuss the effects on detrusor hyperreflexia treated with ginger-salt-isolated moxibustion at "Shenque" (CV 8) and its mechanism. METHODS Thirty female adult SD rats were selected. The model of detrusor hyperreflexia was prepared with complete spinal transection at T9, of which, 20 rats were randomized into a model group (10 rats) and a moxibustion group (10 rats). A sham-operation group (10 rats) was set up for sham-spinal transection. In the moxibustion group, when urine incontinence occurred (about in 2 weeks of modeling), the ginger-salt-isolated moxibustion at "Shenque" (CV 8) was given, 3 moxa cones each time, once a day, continuously for 7 days. After treatment, in each group, the urodynamic parameters were determined, after which, the bladder detrusor was collected. Western blot was used to determine the protein expressions of M2 and M3 receptors. RESULTS Compared with the sham-operation group, the micturition interval was shortened apparently (P<0.01); the maximal bladder pressure was increased apparently (P<0.01); the protein expression of M2 receptor in the detrusor was increased significantly (P<0.05) and that of M3 receptor had no apparent change (P>0.05) in the rats of the model group. Compared with the model group, the micturition interval was longer apparently (P<0.01), the maximal bladder pressure was reduced apparently (P<0.01), the protein expression of M2 receptor in the detrusor was reduced significantly (P<0.05) and that of M3 receptor had no apparent change (P>0.05) in the rats of the moxibustion group.Compared with the sham-operation group, the results of the above indicators were not different significantly in the moxibustion group (all P>0.05). CONCLUSIONS The ginger-salt-isolated moxibustion at "Shenque" (CV 8) suppresses the overactive bladder in the rat with spinal transection and its effect mechanism is possibly relevant with reducing the protein expression of detrusor M2 and inhibiting the excessive contraction of the detrusor.
