Abstract
This paper reports lithium concentrations and isotopic compositions of olivines in the oceanized subcontinental lithospheric mantle (SCLM) peridotites of the Tibetan Yunzhug ophiolite. The results show systematic Li isotope changes with distance from the rim of olivine grains. δ7Li values of olivine in dunites decrease from + 10.46 to + 1.33‰ with increasing distance to olivine rim from 26.15 to 124.71 μm. A negative correlation of δ7Li and Li content in olivine from dunite and harzburgite indicates recent diffusive ingress of Li into the peridotites. The extremely heavy Li isotopic composition requires the seawater or seawater alteration endmember in the mixing model, and reveals Li diffusion from seawater into olivine. As in dunites, olivines in a harzburgite sample show similar variations in δ7Li as a function of distance from the grain rim (e.g., 6.01 to 1.73 in sample 14YZ13). We suggest that the behavior of Li in the oceanized SCLM peridotites may be controlled by Li diffusion from seawater, as Li activity in the liquid state is higher than the solid state in transporting Li through the olivines in the peridotites. This study supports that seawater Li diffusion is one of the important factors for the heterogeneity of mantle Li isotopes in ophiolites.

Abstract
OBJECTIVE This study aims to construct an artificial intelligence (AI) model capable of effectively discriminating between abdominal Henoch-Schönlein purpura (AHSP) and acute appendicitis (AA) in pediatric patients. METHODS A total of 6965 participants, comprising 2201 individuals with AHSP and 4764 patients with AA, were enrolled in the study. Additionally, 53 laboratory indicators were taken into consideration. Five distinct artificial intelligence (AI) models were developed employing machine learning algorithms, namely XGBoost, AdaBoost, Gaussian Naïve Bayes (GNB), MLPClassifier (MLP), and support vector machine (SVM). The performance of these prediction models was assessed through receiver operating characteristic (ROC) curve analysis, calibration curve assessment, and decision curve analysis (DCA). RESULTS We identified 32 discriminative indicators (p < .05) between AHSP and AA. Five indicators, namely the lymphocyte ratio (LYMPH ratio), eosinophil ratio (EO ratio), eosinophil count (EO count), neutrophil ratio (NEUT ratio), and C-reactive protein (CRP), exhibited strong performance in distinguishing AHSP from AA (AUC ≥ 0.80). Among the various prediction models, the XGBoost model displayed superior performance evidenced by the highest AUC (XGBoost = 0.895, other models < 0.89), accuracy (XGBoost = 0.824, other models < 0.81), and Kappa value (XGBoost = 0.621, other models < 0.60) in the validation set. After optimization, the XGBoost model demonstrated remarkable diagnostic performance for AHSP and AA (AUC > 0.95). Both the calibration curve and decision curve analysis suggested the promising clinical utility and net benefits of the XGBoost model. CONCLUSION The AI-based machine learning model exhibits high prediction accuracy and can differentiate AHSP and AA from a data-driven perspective.

Abstract
Poyang Lake (PL), the biggest freshwater lake in China, is situated in the East Asian Monsoon region, and has an important impact on local convection. In general, PL can result in convection in local region when it is a heat source in nighttime of warm season. However, at around noon on 4 May 2020 (PL is a cold source), a convection was triggered about 20 km west of PL, and rapidly enhanced and resulted in lightning when approaching PL, and then quickly weakened and disappeared after entering the main body of PL. In order to explore the convection formation, several observational data and the Weather Research and Forecasting model were applied in this study. Results show that when the convection approaches PL, its rapid enhancement is induced by PL, and after entering the main body of PL, its quick weakening is also resulted from PL. However, the initiation of the convection is mainly induced by the local topography west of PL under a favorable large-scale background. Mechanism analysis indicates that the strong low-level convergence near the west shore of PL associated with lake-land breeze is responsible for the rapid enhancement of the convection, and the low-level divergence over the main body of PL associated with the lake-land breeze and the increase of the low-level stability induced by cooling of PL jointly result in the quick weakening of the convection. The prevailing southerly wind in low level passes through the local topography (Meling Mountain) west of PL, and is divided into southwesterly wind (flow around Meiling) and southerly wind (flow over Meiling), and they converge in the north of Meling, triggering the convection. This study is not only important to deepen the understanding of PL affecting regional weather, but also helpful for improving the refined forecasting of convection near PL.

Abstract
Objective: To understand the current situation of long working hours exposure of couriers in Zhejiang Province, and to analyze the influence of long working hours exposure levels on their occupational stress and depression symptoms, and provide a basis for promoting the physical and mental health of couriers. Methods: From September to December 2021 , 1159 couriers from Zhejiang Express Transport Companies were selected as respondents by cluster sampling, and their basic information were collected. The occupational stress and depression symptoms of the couriers were assessed using the Core Occupational Stress Scale (COSS) and the Patient Health Questionnaire-9 (PHQ-9). The effects of long work hours (>48 h per week) on the occupational stress and depression symptoms of the couriers were analyzed. Results: The average age of 1159 courier in Zhejiang Province was (33.24±8.42) years, the average weekly working hours were (63.21±18.77) h, and 75.15% (871/1159) were long-term workers. The detection rates of occupational stress and depression symptoms in courier were 32.44% (376/1159) and 32.53% (377/1159), respectively. There were significant differences in the detection rates of occupational stress and depression symptoms among couriers with different ages, educational background, marital status, monthly average income, length of service, position or post, shift status, drinking status, and average weekly working hours (P <0.05). The adjusted logistic regression analysis showed that, after adjusting for the influence of confounding factors such as age, educational background, marital status, monthly average income, length of service, position or post, shift status and drinking status, compared with the weekly working hours ≤48 h, weekly working hours of 63-77 h, 78-92 h, ≥93 h were the risk factors for occupational stress (OR=1.547, 95%CI: 1.019-2.350; OR=1.886, 95%CI: 1.184-3.006; OR=2.338, 95%CI: 1.188-4.062) and depression symptoms (OR=1.897, 95%CI: 1.258-2.860; OR=2.041, 95%CI: 1.290-3.230; OR=4.978, 95%CI: 2.551-9.715) of couriers (P<0.05) . Conclusion: Long working hours could increase the risk of occupational stress and depression symptoms among couriers. It is necessary to arrange working hours reasonably to reduce the occurrence of occupational stress and depression symptoms of couriers.

Abstract
BACKGROUND Intervertebral disc degeneration (IDD) is a complex chronic disease involving nucleus pulposus cells (NPCs) senescence, apoptosis, autophagy and extracellular matrix (ECM) degradation. In this study, we aimed to investigate the role of human adipose tissue stem cells (hASCs)-derived exosomal miR-155-5p targeting TGFβR2 in IDD and the mechanisms involved. Then miRNA sequencing was performed, and hASCs-derived Exo (hASCs-Exo) was extracted and characterized. METHODS First, NPCs were treated with different concentrations of LPS. Then miRNA sequencing was performed, and hASCs-Exo was extracted and characterized. NPCs were treated with PBS or autophagy inhibitor 3-MA. NPCs were transfected with miR-155-5p mimic, si-TGFβR2 and negative control. Cell viability, apoptosis, ROS, caspase-1+PI, pyroptosis markers, inflammatory cytokines, autophagy markers, Aggrecan, MMP13, and Akt/mTOR pathway-related factors were measured. Bioinformatics prediction and dual-luciferase were performed to verify the binding sites of miR-155-5p to TGFβR2. Finally, we validated the role of hASCs-derived exosomal miR-155-5p on IDD in vivo. RESULTS LPS promoted pyroptosis of NPCs, and inhibited autophagy and ECM synthesis. MiR-155-5p was characterized as an inflammation-related miRNA in NPCs. HASCs-derived exosomal miR-155-5p inhibited pyroptosis of NPCs and promoted autophagy and ECM synthesis. After bioinformatics prediction and verification, it was found that miR-155-5p targeted TGFβR2. Moreover, miR-155-5p targeted TGFβR2 to promote autophagy and inhibit pyroptosis in NPCs. In vivo experiments revealed that hASCs-derived exosomal miR-155-5p alleviated IDD in rats. CONCLUSIONS HASCs-derived exosomal miR-155-5p alleviated IDD by targeting TGFβR2 to promote autophagy and reduce pyroptosis. Our study may provide a new therapeutic target for IDD. TRANSLATIONAL POTENTIAL OF THIS ARTICLE HASCs-derived exosomal miR-155-5p is expected to be a biomarker for clinical treatment of IDD. Our study may provide a new therapeutic target for IDD.

Abstract
Liver fibrosis is a chronic liver disease with the presence of progressive wound healing response caused by liver injury. Currently, there are no approved therapies for liver fibrosis. Exosomes derived from human adipose mesenchymal stem cells (hADMSCs-Exo) have displayed a prominent therapeutic effect on liver diseases. However, few studies have evaluated therapeutic effect of hADMSCs-Exo in liver fibrosis and cirrhosis, and its precise mechanisms of action remain unclear. Herein, we investigated anti-fibrotic efficacy of hADMSCs-Exo in vitro and in vivo, and identified important metabolic changes and the detailed mechanism through transcriptomic and metabolomic profiling. We found hADMSCs-Exo could inhibit the proliferation of activated hepatic stellate cells through aggravating apoptosis and arresting G1 phase, effectively inhibiting the expression of profibrogenic proteins and epithelial-to-mesenchymal transition (EMT) in vitro. Moreover, it could significantly block collagen deposition and EMT process, improve liver function and reduce liver inflammation in liver cirrhosis mice model. The omics analysis revealed that the key mechanism of hADMSCs-Exo anti-hepatic fibrosis was the inhibition of PI3K/AKT/mTOR signaling pathway and affecting the changes of metabolites in lipid metabolism, and mainly regulating choline metabolism. CHPT1 activated by hADMSCs-Exo facilitated formation and maintenance of vesicular membranes. Thus, our study indicates that hADMSCs-Exo can attenuate hepatic stellate cell activation and suppress the progression of liver fibrosis, which holds the significant potential of hADMSCs-Exo for use as extracellular nanovesicles-based therapeutics in the treatment of liver fibrosis and possibly other intractable chronic liver diseases.

Abstract
Hepatocellular carcinoma (LIHC) accounts for 90% of all liver cancers and is a serious health concern worldwide. Long noncoding RNAs (lncRNAs) have been observed to sponge microRNAs (miRNAs) and participate in the biological processes of LIHC. This study aimed to evaluate the role of the ST8SIA6-AS1-miR-142-3p-HMGA1 axis in regulating LIHC progression. RT-qPCR and western blotting were performed to determine the levels of ST8SIA6-AS1, miR-142-3p, and HMGA1 in LIHC. The relationship between ST8SIA6-AS1, miR-142-3p, and HMGA1 was assessed using luciferase assay. The role of the ST8SIA6-AS1-miR-142-3p-HMGA1 axis was evaluated in vitro using LIHC cells. Expression of ST8SIA6-AS1 and HMGA1 was significantly upregulated, whereas that of miR-142-3p was markedly lowered in LIHC specimens and cells. ST8SIA6-AS1 accelerated cell growth, invasion, and migration and suppressed apoptosis in LIHC. Notably, ST8SIA6-AS1 inhibited HMGA1 expression by sponging miR-142-3p in LIHC cells. In conclusion, sponging of miR-142-3p by ST8SIA6-AS1 accelerated the growth of cells while preventing cell apoptosis in LIHC cells, and the inhibitory effect of miR-142-3p was abrogated by elevating HMGA1 expression. The ST8SIA6-AS1-miR-142-3p-HMGA1 axis represents a potential target for the treatment of patients with LIHC.

Abstract
Objective The reverse digital artery island flap (RDAF) is widely used in repairing fingertip skin defects based on its good appearance and practicability. However, the donor area of the flap needs skin grafting, which can lead to complications. This retrospective study explored the clinical application of digital dorsal advance flap (DDAF) in repairing the donor site of the reverse digital artery island flap. Method From June 2019 to February 2022, 17 patients with a soft tissue defect of the finger had been restored with the reverse digital artery island flap, and at the same time, the donor area was repaired with digital dorsal advance flap (DDAF). The sensitivity, the active range of motion (ROM) and patient satisfaction were assessed after the operation. Results All flaps survived completely without skin grafting with only one linear scar. The sensory and motor functions of all patients recovered well. Assessment based on the Michigan Hand Outcomes Questionnaire (MHQ) showed satisfactory functional recovery for all patients. Conclusions Reconstruction using RDAF combined with DDAF represents an effective alternative for repairing fingertip skin defects.

Abstract
BACKGROUND The 523 poly-T length polymorphism (rs10524523) in TOMM40 has been reported to influence longitudinal cognitive test performance within APOE ε3/3 carriers. The results from prior studies are inconsistent. It is also unclear whether specific APOE and TOMM40 genotypes contribute to heterogeneity in longitudinal cognitive performance during the preclinical stages of AD. OBJECTIVES To determine the effects of these genes on longitudinal cognitive change in early preclinical stages of AD, we used the clinical trial data from the recently concluded TOMMORROW study to examine the effects of APOE and TOMM40 genotypes on neuropsychological test performance. DESIGN A phase 3, double-blind, placebo-controlled, randomized clinical trial. SETTING Academic affiliated and private research clinics in Australia, Germany, Switzerland, the UK, and the USA. PARTICIPANTS Cognitively normal older adults aged 65 to 83. INTERVENTION Pioglitazone tablet. MEASUREMENTS Participants from the TOMMORROW trial were stratified based on APOE genotype (APOE ε3/3, APOE ε3/4, APOE ε4/4). APOE ε3/3 carriers were further stratified by TOMM40'523 genotype. The final analysis dataset consists of 1,330 APOE ε3/3 carriers and 7,001 visits. Linear mixed models were used to compare the rates of decline in cognition across APOE groups and the APOE ε3/3 carriers with different TOMM40'523 genotypes. RESULTS APOE ε3/4 and APOE ε4/4 genotypes compared with the APOE ε3/3 genotype were associated with worse performance on measures of global cognition, episodic memory, and expressive language. Further, over the four years of observation, the APOE ε3/3 carriers with the TOMM40'523-S/S genotype showed better global cognition and accelerated rates of cognitive decline on tests of global cognition, executive function, and attentional processing compared to APOE ε3/3 carriers with TOMM40'523-S/VL and VL/VL genotypes and compared to the APOE ε3/4 and APOE ε4/4 carriers. CONCLUSIONS We suggest that both APOE and TOMM40 genotypes may independently contribute to cognitive heterogeneity in the pre-MCI stages of AD. Controlling for this genetic variability will be important in clinical trials designed to slow the rate of cognitive decline and/or prevent symptom onset in preclinical AD.

Abstract
Background Inflammation, immunity, and nutrition status play important roles in tumorigenesis, progression, and metastasis. This study aimed to evaluate the prognostic value of Inflammation-Immunity-Nutrition Score (IINS) for overall survival (OS) and progression-free survival (PFS) in patients with hepatocellular carcinoma (HCC) undergoing radical surgery. Methods A total of 204 HCC patients who met the criteria were included in this retrospective study: 144 in the prediction model and 60 in the validation model. IINS was constructed based on the sum of classification scores of preoperative high-sensitivity C-reactive protein (hsCRP), lymphocyte (LYM), and albumin (ALB). The associations between the IINS group and the clinicopathologic characteristics were analyzed using Pearson’s χ2 test or Fisher’s exact test. Multivariate Cox regression analysis was used to evaluate variables significant on univariate analysis. Kaplan-Meier survival curves were conducted to investigate the prognostic values of IINS, Alpha-fetoprotein (AFP) and IINS-AFP classification. The prognostic performances of all the potential prognostic factors were further compared by receiver operating characteristic (ROC) curve, and time-dependent ROC curve. The internal validation and external validation were used to ensure the credibility of this prediction model. Results The patients were divided into low and high IINS groups according to the median of IINS. According to multivariate Cox regression analyses, the Barcelona Clinic Liver Cancer (BCLC) Stage (P=0.003), AFP (P=0.013), and IINS (P=0.028) were independent prognostic factors for OS, and BCLC Stage (P=0.009), microvascular invasion (P=0.030), and IINS (P=0.031) were independent prognostic factors for PFS. High IINS group were associated with significantly worse OS and PFS compared with low IINS group (P<0.001; P=0.004). In terms of clinical prognosis, IINS-AFP classification was good in group I, moderate in group II, and poor in group III. Group I had a longer OS (P<0.001) and PFS (P=0.008) compared with group II and III. ROC analysis revealed that IINS-AFP classification had a better prognostic performance for OS (AUC: 0.767) and PFS (AUC: 0.641) than other predictors, excluding its slightly lower predictive power for PFS than IINS. The time-dependent ROC curves also showed that both IINS (12-month AUC: 0.650; 24-month AUC: 0.670; 36-month AUC: 0.880) and IINS-AFP classification (12-month AUC: 0.720; 24-month AUC: 0.760; 36-month AUC: 0.970) performed well in predicting OS for HCC patients. Furthermore, the internal validation and external validation proved that IINS had good predictive performance, strong internal validity and external applicability, and could be used to establish the prediction model. Conclusion Inflammation-immunity-nutrition score could be a powerful clinical prognostic indicator in HCC patients undergoing radical surgery. Furthermore, IINS-AFP classification presents better prognostic performance than IINS or AFP alone, and might serve as a practical guidance to help patients adjust treatment and follow-up strategies to improve future outcomes.

Abstract
BACKGROUND There are no validated biomarkers that can predict the clinical benefit of immune checkpoint blockers against the programmed cell death protein 1 (PD-1) treatments in hepatocellular carcinoma (HCC). This study aimed to investigate the prognostic value of inflammation-immunity-nutrition score (IINS) in patients with HCC treated with anti-PD-1 therapy. METHODS A consecutive series of 101 HCC patients treated with PD-1 inhibitors in Sichuan Provincial People's Hospital between January 2018 and August 2020 were enrolled in the retrospective study. IINS (0-6) was constructed based on pretreatment high-sensitivity C-reactive protein (hsCRP), lymphocyte (LYM), and albumin (ALB). The patients were divided into high and low IINS groups according to IINS values. Prognostic values of each variable were evaluated with univariate and multivariate time-dependent Cox regression analyses. Survival curves were calculated and compared using the Kaplan-Meier method and log-rank test. The prognostic performance of IINS was further compared with that of other traditional prognostic indicators by receiver operating characteristic (ROC) curve and the areas under the ROC curve. RESULTS Patients with low IINS had longer overall survival (OS) (HR: 4.711, 95% CI: 1.80-12.37, p = .001) and progression-free survival (HR: 3.411, 95% CI: 1.79-6.51, p < .0001) than those with high IINS. The multivariate analysis identified IINS (HR: 3.746, 95% CI: 1.05-13.38, p = .042) and tumor number (HR: 5.111, 95% CI: 1.075-24.299, p = .04) as independent prognostic factors. According to ROC analysis, IINS (AUC =0.729, 95% CI: 0.597-0.861, p = .002) presented better prognostic performance than other traditional prognostic indicators. The area of the IINS-CA19-9 under the ROC curve (AUC) was higher than that of the IINS or CA19-9 levels for the prediction of OS. CONCLUSION The results suggest that IINS may be an independent prognostic indicator for HCC patients treated with anti-PD-1 therapy. IINS-CA19-9 classification may be more effective in predicting clinical benefit of anti-PD-1 therapy in HCC patients.

Abstract
Background Gynura segetum (GS) is widely used in medical care and in community settings in China as the herbal remedy. It is widely thought to have antiphlogistic properties and pain relief in traditional Chinese medicine. It has been reported that GS can cause chronic drug-induced liver injury (DILI), manifested as hepatic sinusoid obstruction syndrome (HOSO). But case reports of acute DILI developing acute liver failure (ALF) due to GS are extremely rare. Case presentation We report a case of a 63-year-old female patient with hepatolithiasis for more than 6 years. There were no deterioration of liver function and no history of viral liver disease, autoimmune liver disease, blood transfusion or surgical allergy before operation. ALF and grade II liver encephalopathy occurred after partial hepatectomy. To follow up the medical history, the patient has been taking GS (Tusanqi) for a year and a half. The causality assessment was done by the updated Roussel Uclaf Causality Assessment Method, and the possibility of DILI caused by GS as highly probable for the score was 6 points. Excluding other causes, a diagnosis of DILI-associated ALF was established. After symptomatic support and artificial liver support system (ALSS) treatment, the clinical symptoms and signs of the patients were significantly improved. After discharge, the liver function of the patients returned to normal. Conclusions Based on this rare case of severe liver injury, we recommend that timely prevention, identification, and appropriate management of DILI is essential for patients with a history of taking GS and other hepatotoxic drugs, and careful monitoring of liver function for patients with DILI could avoid ALF as far as possible.

Abstract
The long non-coding RNA plasmacytoma variant translocation 1 (lncRNA PVT1) has been implicated in the progression of abdominal aortic aneurysms (AAA). However, the detailed mechanism requires further analysis. Our study was aimed at interrogating the mechanism of PVT1 in an H2O2-induced AAA model in vitro. The expression of lncRNA PVT1, microRNA miR-3127-5p, and NCK-associated protein 1-like (NCKAP1L) was examined in AAA tissues and H2O2-treated vascular smooth muscle cells (VSMCs). Cell proliferation was assayed using Cell Counting Kit-8 (CCK8) and 5-Bromodeoxyuridine (BrdU) assays. Meanwhile, 5-Ethynyl-2'-deoxyuridine (EdU) staining was performed to assess cell apoptosis and caspase-3 activity. IL-1β and caspase-1 expression was also assessed using Western blotting to determine inflammasome activation in H2O2-treated VSMCs. Luciferase reporter assays addressed the possible interaction between miR-3127-5p and PVT1 or NCKAP1L, which was predicted by starBase analysis. PVT1 and NCKAP1L expression was elevated in AAA tissues and induced the AAA model in vitro, whereas miR-3127-5p showed the opposite trend. Functionally, PVT1 silencing promoted cell proliferation and reduced the apoptotic rate and inflammasome activation in H2O2-treated VSMCs. Mechanical investigation demonstrated that PVT1 acted as a sponge of miR-3127-5p to modulate NCKAP1L expression, resulting in suppression of VSMC proliferation, induction of apoptosis, and activation of inflammation. In conclusion, PVT1 participates in AAA progression through the miR-3127-5p/NCKAP1L axis and may be a promising biosignature and therapeutic target for AAA.

Abstract
Objective: To explore the effect of atractylenolide-1 (ATL-Ⅰ) on alveolar macrophages in silicosis patients. Methods: In December 2019, 12 male silicosis patients treated in Beidaihe Sanatorium for Chinese Coal Miners from July to September 2019 were selected by random sampling. Their alveolar macrophages were collected and divided into control group, ATL-Ⅰ group (100 μmol/L) and dimethyl sulfoxide (DMSO) group (100 μmol/L) . The exprossion levels of inflammatory factor interleukin-1β (IL-1β) , interleukin-6 (IL-6) , tumor necrosis factor α (TNF-α) were detected by enzyme-linked immunosorbent assay. The expression levels of autophagy associated protein microtubule associated protein light chain 3 (LC3) , autophagy substrate protein p62, lysosome associated membrane protein 2 (LAMP2) , apoptosis associated protein Cleaved caspase-3, nuclear factor kappa B (NF-κB) and its phosphorylated form (p-NF-κB) were detected by Western blot. Results: Compared with the control group and DMSO group, the expression levels of IL-1β, IL-6, TNF-α in alveolar macrophages decreased significantly in the ATL-Ⅰ group (P<0.05) , and the expression levels of p-NF-κB, the ratio of LC3-Ⅱ/LC3-Ⅰ also decreased significantly in the ATL-Ⅰ group (P<0.05) . However, the expression levels of NF-κB, LAMP2, p62 and Cleaved caspase-3 in the ATL-Ⅰ group were not statistically different from those in the control group and DMSO group (P>0.05) . There was no statistically significant differences in the expression of the above indexes between the control group and DMSO group (P>0.05) . Conclusion: ATL-Ⅰ may reduce the release of inflammatory factors from alveolar macrophages and inhibit the activity of autophagy in silicosis patients, but it may not reduce the level of apoptosis.

Abstract
BACKGROUND Patients with chronic rhinosinusitis (CRS) often have Eustachian tube dysfunction (ETD) symptoms. This study aimed to prospectively investigate the effect of endoscopic sinus surgery (ESS) on improvement of Eustachian tube function in CRS patients with ETD from a Chinese population and determine factors associated with improvement. METHODS A prospective study was performed in CRS patients with ETD who underwent ESS from 3 tertiary medical centers in south China. The Eustachian tube Dysfunction Questionnaire 7 (ETDQ-7), Sinonasal Outcome Test 22 (SNOT-22), tympanograms, endoscopic findings and Valsalva maneuver were recorded and analyzed preoperatively and postoperatively at 8-12 weeks. RESULTS A total of 70 CRS patients with ETD were included in this study. The ETDQ-7 score and the ability of positive Valsalva maneuver in CRS patients were significantly improved postoperatively at 8-12 weeks. The number of patients with type A tympanogram was increased postoperatively. Reduced Eustachian tube mucosal inflammation was also observed postoperatively. In addition, ESS appeared to reverse slight tympanic membrane atelectasis after 8-12 weeks. Moreover, improvement in tympanogram was presented in more than half of CRS patients with concomitant otitis media with effusion postoperatively at 8-12 weeks. Univariate and multivariate analysis revealed failure of normalization of ETDQ-7 postoperatively was associated with concomitant allergic rhinitis and higher preoperative SNOT-22 score. CONCLUSIONS This study confirms Eustachian tube function is often improved after ESS in CRS patients with ETD. Concomitant allergic rhinitis and higher preoperative SNOT-22 score are associated with failure of normalization of ETD symptoms.

Abstract
Objective: To study the effect of occupational exposure to non-steady state noise on hearing loss in the general equipment manufacturing industry, and to explore the feasibility of applying kurtosis index to evaluate hearing loss caused by non-steady state noise. Methods: A total of 233 workers exposed to non-steady state noise in 6 general equipment manufacturing enterprises were selected as the observation group, and 237 workers exposed to steady noise in 4 textile enterprises were selected as the control group between 2012 and 2018. Personal normalized continuous A-weighted sound pressure level equivalent to an 8 h-working-day (L(Aeq, 8 h)) was determined by a noise dosimeter. Cumulation noise exposure (CNE) was calculated from L(Aeq, 8 h) and related working age, and the CNE was adjusted by using noise kurtosis (CNE' after adjustment) . Meanwhile, questionnaires and hearing loss tests were performed for all subjects. The changes in the threshold of high-frequency hearing and the incidence of high-frequency hearing loss caused by noise in the two groups were compared before and after the adjustment of the kurtosis of CNE. The correlation between CNE and the incidence of high-frequency hearing loss before and after kurtosis adjustment was analyzed. Results: There was an difference between the 3000-8000 Hz hearing threshold of workers in different CNE groups (P<0.05) . logistic regression analysis showed that CNE was a risk factor of high-frequency hearing loss for workers in the observation group (OR=1.189, P<0.05) , and trend Chi-square test showed that the incidence of high-frequency hearing loss increased with CNE levels (χ(2)(trend)=34.415, P<0.05) .Before the kurtosis adjustment, in the CNE 95~<110 dB (A) ·year level group, the incidence of high-frequency hearing loss and the high-frequency hearing threshold in the observation group were significantly higher than those in the control group (P<0.05) . After kurtosis adjustment, there was no significant difference in the incidence of high-frequency hearing loss between the observation group and the control group in each level group (P>0.05) . The correlation between CNE after kurtosis adjustment and the incidence of high-frequency hearing loss was better than that before adjustment (after R(2) adjustment >before R(2) adjustment) . Conclusion: The effect of non-steady state noise on high-frequency hearing loss of workers in general equipment industry increases with the increase of CNE, and the effect of non-steady state noise on high-frequency hearing loss of workers is greater than that of steady noise. CNE' can be used to evaluate the hearing loss caused by non-steady state noise.

Background
Psychological stress is associated with high incidence of coronary heart disease and increases the risk of mortality and poor health status. Although a few studies have investigated psychological stress in this population, this problem is usually unrecognized and untreated in most Chinese patients with acute coronary syndrome. There is insufficient information regarding the features of psychological stress and associated factors among this population.
Purpose
This study aimed to assess the level of psychological stress and to identify its correlates in Chinese patients with acute coronary syndrome.
Methods
Patients aged over 18 years and with acute coronary syndrome were invited to participate in a cross-sectional survey in two tertiary public hospitals in China, from June to July 2019. A total of 332 patients completed measures of sociodemographic and clinical characteristics, psychological stress (10-item Perceived Stress Scale), and illness perception (Brief Illness Perceptions Questionnaire). Independent sample t-tests, bivariate correlations, and multivariable linear regression were performed to analyze potential correlates, including age, gender, education level, employment status, income, episode of illness, revascularization procedure, comorbidities, body mass index, blood pressure, blood glucose, blood lipids, and illness perception.
Results
The average patient age was 62.2 years, 67.5% were male, and 54.2% had less than high school education. The mean score for psychological stress was 21.30 ± 3.99 and 66.9% of patients had high psychological stress (score ≥ 20). Multivariable regression analysis showed that being overweight/obesity versus normal weight (body mass index: ≥ 24 kg/m2 versus < 24 kg/m2) was associated with lower psychological stress (β = -0.134, p = 0.007). Having a high level of fasting blood glucose (≥ 6.1 mmol/L) versus normal fasting blood glucose (< 6.1 mmol/L) was associated with high psychological stress (β = 0.123, p = 0.017). Additionally, negative cognitive illness perception (β = 0.190, p = 0.01), negative emotional illness perception (β = 0.290, p < 0.001), and poor illness understanding (β = 0.118, p = 0.032) were associated with high psychological stress.
Conclusions
Patients with acute coronary syndrome experience high psychological stress that is significantly correlated with body mass index, fasting blood glucose, and illness perception. Health professionals should recognize this issue and interventions looking to relive psychological stress may benefit from targeting these correlates.

Abstract
Background:Serum fibrotic markers for systemic sclerosis (SSc) remain limited. The Enhanced Liver Fibrosis (ELF) score, originally derived and validated in patients with chronic liver disease, is an algorithm combining 3 serum markers, known as procollagen type III amino terminal propeptide (PIIINP), tissue inhibitor of metalloproteinases 1 (TIMP-1), and hyaluronic acid (HA). The combined score was proved to be superior to the single components in reflecting the severity of liver fibrosis. However, the performance of ELF score and its components has not been fully validated in SSc.Objectives:To investigate PIIINP, TIMP-1, HA, and the combined algorithm ELF score as fibrotic markers for SSc skin involvement.Methods:Eighty SSc patients (44 dcSSc and 36 lcSSc), fulfilling the 2013 ACR/EULAR criteria with the absence of chronic liver diseases, were enrolled. Eighty age- and sex- matched healthy controls were also included. Serum PIIINP and HA levels were quantified by chemiluminescence immunoassay. Serum TIMP-1 levels were determined by enzyme-linked immunosorbent assay. The ELF score was calculated using the formula ELF score= 2.494 + 0.846*ln(HA) + 0.735*ln(PIIINP) + 0.391*ln(TIMP-1). Results were correlated with clinical profiles including modified Rodnan skin score (mRSS) and interstitial lung disease (ILD).Results:Compared with healthy controls, patients with SSc showed significantly elevated serum PIIINP (11.2±4.8 vs. 5.73±1.4μg/L, p<0.001), TIMP-I (123.7±78.6 vs. 67.8±26.5 ng/ml, p<0.001), and ELF score (10.5±0.9 vs. 9.7±0.4, P<0.001). Even higher levels of PIIINP, TIMP-1, and ELF score were observed in dcSSc patients, compared with lcSSc patients (p<0.001, p=0.024, p=0.003, respectively). No significant difference was found in the levels of serum HA between patients and controls. Strong correlations were observed between mRSS and ELF score (r=0.54, p<0.001), and between mRSS and PIIINP(r=0.62, p<0.001), whereas only weak correlations could be observed between mRSS and TIMP-1 (r=0.28, p=0.02), and between mRSS and HA (r=0.26, p=0.03). When stratified by ELF score, using cutoffs proposed for liver fibrosis and cirrhosis, SSc patients with ELF<9.8 showed the lowest mRSS on average, while patients with ELF>11.3 showed the highest (p<0.001). When stratified by serum PIIINP levels, using the 25th and 75th percentiles, SSc patients with serum PIIIINP levels<7.8μg/L showed the lowest mRSS on average, while patients with PIIINP>14.0μg/L showed the highest (p<0.001). Neither the ELF score nor its components showed significant difference between patients with and without ILD.Conclusion:The ELF score could be used for reflecting the severity of overall skin involvement in SSc, and serum PIIINP also increased in parallel with the increase of mRSS. Longitudinal prospective studies exploring ELF score or serum PIIINP as fibrotic markers and outcome measures of SSc are warranted.References:[1]Lichtinghagen R, Pietsch D, Bantel H, et al.

Abstract
Background:Interferon-inducible protein 16 (IFI-16) is constitutively expressed in vascular endothelial cells and can inhibit the proliferation of human endothelial cells and the formation of capillary-like structures in vitro. Anti-IFI-16 antibodies were reported in 21%-29% of patients with systemic sclerosis (SSc) and were associated with digital vascular events in a few retrospective studies.Objectives:To evaluate the presence and the clinical implication of anti-IFI-16 antibodies in Chinese SSc cohort, focusing on the associations with vasculopathy indexes, and to investigate the predictive value of anti-IFI-16 antibodies for the development of digital ulcers (DUs) in SSc prospectively.Methods:Patients with SSc presenting to our center between July 2018 and September 2018 were prospectively enrolled. Serum from 42 SSc patients and 42 age- and sex-matched healthy controls were analyzed for anti-IFI-16 antibodies by enzyme-linked immunosorbent assay (ELISA), and was considered positive if the optical density (OD) value was above the mean OD of controls plus two standard deviations. Tissue immunofluorescence was used to evaluate the expression of IFI16 in skin biopsy samples obtained from SSc patients and normal controls. At baseline, nailfold video-capillaroscopy was performed to assess nailfold capillary density of SSc patients. Power Doppler ultrasound was used to grade finger pulp blood flow (0-no observed flow; 1-decreased flow; 2-normal flow), and to measure ulnar and radial artery blood flow and resistive index (RI). All patients were followed up for 6 months to see whether they experienced new onset or recurrent DUs. The association of anti-IFI-16 antibodies with DUs was analyzed using logistic regression.Results:Of the 42 SSc patients, 8 (19.0%) were positive for anti-IFI-16 antibodies. Immunofluorescence of skin biopsy samples from SSc patients exhibited enhanced staining of IFI-16 in the dermis, and colocalization with endothelial marker CD31. SSc patients who were positive for anti-IFI-16 antibodies showed higher ulnar artery RI at baseline (0.95±0.09 vs. 0.86±0.09, p=0.015), while no significant differences were found for other vascular parameters, nor for clinical or demographic profiles. Within 6-month follow-up, 14 (33.3%) patients experienced new-onset or recurrent DUs. Univariate logistic regression revealed the presence of DUs at enrollment (p=0.009), anti-IFI-16 antibody (p=0.012), finger pulp blood flow (p=0.027), and ulnar artery RI (p=0.008) could be the predictors for the development of DUs. Multivariate analysis further identified DUs at enrollment (odds ratio [OR]: 10.85; 95% confidence interval [CI]: 1.61-73.18; p=0.014) and anti-IFI-16 antibody (OR: 15.00; 95% CI: 1.13-199.18; p=0.040) as independent risk factors. Among patients without DUs at enrollment, new-onset ulcers occurred in 80% (4/5) and 4.5% (1/22) of those with and without anti-IFI-16 antibody, respectively (p=0.001).Conclusion:Anti-IFI-16 antibody is associated with vasculopathy in SSc and could be used as a novel biomarker for indicating the development of DUs.References:[1]McMahan ZH, Shah AA, Vaidya D, et al.

Abstract
High pressure homogenization (HPH) offers new opportunities for food pasteurization/sterilization. Escherichia coli and Staphylococcus aureus suspended in phosphate buffered saline (PBS) buffer, milk and apple juice at initial concentration of ~106 log10 CFU per ml were subjected to HPH treatments up to 200 MPa with inlet temperatures at 4-40°C. After HPH at 200 MPa with the inlet temperature at 40°C, the count of E. coli suspended in PBS, milk and apple juice reduced by 3·42, 3·67 and 3·19 log10 CFU per ml respectively while the count of S. aureus decreased by 2·21, 1·02 and 2·33 log10 CFU per ml respectively suggesting that S. aureus was more resistant. The inactivation data were well fitted by the polynomial equation. Milk could provide a protective effect for S. aureus against HPH. After HPH at 200 MPa with the inlet temperature at 20°C, the cell structure of E. coli was destroyed, while no obvious damages were found for S. aureus.

Abstract
OBJECTIVE To explore the molecular mechanism of umbilical cord blood mesenchymal stem cells (UCBMSCs) in the treatment of advanced osteoarthritis pain. METHODS Normal healthy rats were selected to establish advanced osteoarthritis (OA) model, and the rats were randomly divided into control group, intravenous group, intracavitary group and intrathecal group. The intravenous group received intravenous injection of UCBMSCs, intracavitary group received intra-articular injection of UCBMSCs, and intrathecal group received subarachnoid injection of UCBMSCs. The pain behavior and serum pro-inflammatory factor levels were evaluated before and after treatment. microRNA-29a-3p and FOS mRNA in spinal dorsal horn was detected using qPCR, the phosphorylation of c-fos protein and NR1, NR2B, ERK and PKCg was detected using Western blot, and the level of LncRNA H19 was detected using qPCR. RESULTS LncRNA H19 was enriched in the exosomes of UCBMSCs. microRNA-29a-3p was the target gene of LncRNA H19, while FOS was the downstream target of microRNA-29a-3p. Pain and inflammation of rats in the intrathecal group improved best, and the phosphorylation levels of c-fos and NR1, NR2B, ERK and PKCg in the spinal dorsal horn of the intrathecal group decreased. LncRNA H19 regulated the central sensitization of astrocytes through microRNA-29a-3p/FOS axis. CONCLUSION Intrathecal injection of umbilical cord blood mesenchymal stem cells can improve the pain and central sensitization of advanced osteoarthritis through LncRNA H19/microRNA-29a-3p/FOS axis.

Abstract
OBJECTIVES To investigate the influence of cyclosporin A (CsA) pre-treatment and etomidate (ETO) post-treatment on lung injury induced by limb ischemia-reperfusion (I/R) in rats. METHODS Rats were randomly divided into five groups: sham, I/R, I/R+CsA, I/R+ETO, and I/R+CsA+ETO. Limb I/R lung injury was established by bilateral clamping of the femoral arteries for 2 hours. Following reperfusion for 3 hours, blood gas analysis was performed. Pathological changes were assessed using immunohistochemistry. The apoptosis index (AI) and wet/dry weight ratio (W/D) were calculated. Levels of Fas protein and FasL mRNA were assessed by western blotting and RT-PCR, respectively. Tumor necrosis factor (TNF)-α and interleukin (IL)-1β were detected by ELISA. RESULTS I/R resulted in decreased PaO2 but increased AI, W/D, Fas, FasL mRNA, TNF-α and IL-1β. Scattered punctate apoptosis and necrosis were observed by immunohistochemistry. Compared with the I/R group, the I/R+ETO and I/R+CsA groups showed increased SpO2, decreased AI, W/D, Fas, FasL mRNA, TNF-α and IL-1β, and decreased numbers of apoptotic and necrotic cells. Combined treatment with CsA+ETO resulted in more dramatic changes in these parameters. CONCLUSIONS ETO post-treatment and CsA pretreatment reduced lung injury induced by limb I/R in rats. The mechanism may be related to synergistic inhibition of Fas/FasL signaling.

Abstract
Nitrogen (N) could affect storage root growth and development of sweet potato. To manage external N concentration fluctuations, plants have developed a wide range of strategies, such as growth changes and gene expression. Five sweet potato cultivars were used to analyse the functions of N in regulating storage root growth. Growth responses and physiological indicators were measured to determine the physiological changes regulated by different N concentrations. Expression profiles of related genes were analysed via microarray hybridization data and qRT-PCR analysis to reveal the molecular mechanisms of storage root growth regulated by different N concentrations. The growth responses and physiological indicators of the five cultivars were changed by N concentration. The root fresh weight of two of the sweet potato cultivars, SS19 and GS87, was higher under low N concentrations compared with the other cultivars. SS19 and GS87 were found to be having greater tolerance to low N concentration. The expression of N metabolism and storage root growth related genes was regulated by N concentration in sweet potato. These results reveal that N significantly regulated storage root growth. SS19 and GS87 were more tolerant to low N concentration and produced greater storage root yield (at 30 days). Furthermore, several N response genes were involved in both N metabolism and storage root growth.

Abstract
PURPOSE We aimed to explore the risk factors of preoperative sleep quality in patients with lumbar spinal stenosis (LSS) and the association of sleep-related beliefs with sleep quality in these patients. METHODS Sleep quality and related risk factors of sleep quality disturbances in patients with LSS preoperatively were assessed by questionnaires. Pittsburgh Sleep Quality Index (PSQI) for sleep quality, Oswestry Disability Index (ODI) for clinical outcomes, Visual Analog Scale for Pain (VAS Pain), Self-Rating Anxiety Scale (SAS) for anxiety level, and Dysfunctional Beliefs and Attitudes about Sleep (DBAS-16) for sleep-related beliefs were assessed. Bivariate logistic regression analysis was used to assess the risk factors of sleep quality disturbances. RESULTS A total of 227 patients were enrolled, mean age 64 years (SD 13.1), 119 women (52%). The incidence of sleep quality disturbances in patients was 37% (83/227). Increased DBAS-16 scores (OR = 0.781; 95% CI, 0.725-0.841; p < 0.001) significantly decreased the probability of developing sleep quality disturbances, while increased anxiety levels (OR = 1.241; 95% CI, 1.152-1.337; p < 0.001) significantly increased the probability of developing sleep quality disturbances in patients. Factors including educational level, increased age, sex, preoperative length of stay, VAS Pain scores, and ODI scores showed no significant association and were therefore excluded from the model. CONCLUSIONS High levels of anxiety and mistaken sleep-related beliefs were risk factors of sleep quality disturbances in patients with LSS before surgery. The more mistaken sleep-related beliefs were, the greater the probability of sleep disturbances.

Abstract
Background The malignant tumor hepatocellular carcinoma (HCC) has a poor prognosis and ineffective therapeutic options. miR-378a-5p is a micro-ribonucleic acid (miRNA) that is overexpressed in many cancers. However, its role in the progression of human HCC is unclear. Methods Quantitative real-time polymerase chain reaction (qRT-PCR) was used to measure miR-378a-5p levels in tissues from patients with HCC and from HCC cell lines. Following transfection, flow cytometry and cell viability assays were used to measure cell proliferation. HCC cell invasive and migration capacities were assessed using Transwell assays. Western blots were performed with HCC cells to identify the expression of vascular endothelial growth factor (VEGF). Results The HCC tissues and cells had significantly reduced miR-378a-5p expression compared with normal liver tissues and cells, while miR-378a-5p mimics suppressed the colony formation, viability, migration and invasive capacity of HCC cells. The HCC tissues and cell lines had upregulated VEGF expression. In HCC cells, miR-378a-5p expression was negatively correlated with VEGF expression, and miR-378a-5p targeted VEGF in HCC cells. Conclusions miR-378a-5p improved the HCC prognosis and suppressed HCC progression by targeting the VEGF pathway.

Abstract
Abstract
Background
An increasing number of people are living with coronary heart disease (CHD) globally. Psychological conditions such as stress, depression, and anxiety are prevalent for people with CHD, which impose a great challenge for secondary prevention of CHD. Mindfulness-based interventions (MBIs), which incorporate mindfulness skills and cognitive or behavioural therapy, are suggested as a promising approach to help patients with CHD to improve their psychological health. However, the effectiveness of MBIs for patients with CHD has not been systematically reviewed.
Purpose
To synthesise the evidence regarding the effects of MBIs on reducing perceived stress, depression, and anxiety in patients with CHD.
Methods
Search was conducted in seven English electronic databases and two Chinese electronic databases from inception to January 2019. Randomized controlled trials (RCTs) that evaluated the effects of MBIs on stress, depression, and anxiety in adults with CHD were included. Two reviewers independently screened records for eligibility, extracted data, and assessed risks of bias using the Cochrane tool. Meta-analysis was conducted by combining the standard mean difference (SMD) with 95% confidence interval (CI) of post-intervention outcome measures using Review Manager Version 5.3. We used a fixed-effects model if no significant heterogeneity (I² < 50%), while in case of significant heterogeneity (50% < I² < 75%), we used a random-effects model.
Results
Six RCTs involving 473 participants were included. Five of all studies compared MBIs with inactive controls (i.e., usual care and waitlist control). The remaining study utilized a self-help group that received a booklet containing identical mindfulness information as an active control. There were high concerns about the risk of bias across studies, mainly in performance bias and detection bias. The meta-analysis of two studies showed MBIs may reduce perceived stress at post-intervention (SMD -0.82; 95% CI -1.28 to -0.36; P < 0.001; I² 0%) compared with inactive controls. Compared with active control, the single study did not observe a significant reduction of perceived stress in intervention group. The meta-analysis of five studies revealed that MBIs appear effective in reducing depression (SMD -1.08; 95% CI -1.28 to -0.87; P < 0.001; I² 22%) and anxiety (SMD -1.16; 95% CI -1.57 to -0.75; P < 0.001; I² 71%) immediately after intervention, compared with inactive or active controls.
Conclusions
The results of this review provide evidence for the effects of MBIs on reduction in perceived stress, depression and anxiety at post-intervention in patients with CHD. However, these findings need to be interpreted with caution given the small sample size and methodological limitations within included studies. Rigorous-designed research is urgently needed to further confirm the effectiveness of MBIs on improving psychological health and explore its sustainable effects in patients with CHD.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is the common disease in the liver, which is associated with metabolic syndrome and hepatocellular carcinoma. Accumulated evidence establishes that small non-coding microRNAs (miRNAs) contribute to the initiation and progression of NAFLD. However, the molecular repertoire of miRNA in NAFLD is still largely unknown. Here, using an integrative approach spanning bioinformatic analysis and functional approaches, we demonstrate that miR-124-3p participates in the development of NAFLD by directly targeting preadipocyte factor-1 (Pref-1). In response to high-fat diet (HFD), expression of miR-124-3p was increased in the liver. Inhibition of miR-124-3p expression led to a dramatic reduction of triglyceride contents in hepatocytes, in parallel with decreased inflammatory factors. Mechanistically, miR-124-3p directly controls the transcription of Pref-1, a secretory factor that has been proved to resist metabolic syndrome. Our work identifies a novel molecular axis in hepatosteatosis, and highlights miR-124-3p/Pref-1 as potential targets for clinical interventions of NAFLD.

Abstract
AIM To translate the Compliance with Annual Diabetic Eye Exams Survey (CADEES) into Chinese, allowing assessment of its reliability and validity, and to identify variables that predict attendance at annual eye examinations. METHODS People with vision-threatening diabetic retinopathy were recruited from the Shanghai Diabetic Eye Study. The study involved three phases: (1) translation and cross-cultural adaptation, (2) a pilot study (n = 496) to evaluate the psychometric properties of the Chinese-CADEES, and (3) a primary cross-sectional survey (n = 3818) to assess self-reported attendance at annual eye examinations. Factors related to non-attendance were identified using univariate analysis, and then a multiple logistic regression model. Finally, a component model and individual item models were built to predict attendance. RESULTS The Chinese-CADEES had satisfactory reliability and validity. The issue of low attendance at annual eye examinations was serious. In addition to 13 health belief items, living in semi-urban suburban areas, shorter duration of diabetes, poor glucose control, lower education level, better presenting visual acuity and milder diabetic retinopathy diagnosis were significantly related to non-attendance. The multivariate predictive model was able to predict, with 64.7% accuracy, whether or not participants were going to attend annual eye examinations and explained ~ 11.3% of the variance in attendance. CONCLUSIONS The Chinese-CADEES showed good reliability and validity for predicting attendance at annual eye examinations in people with diabetic retinopathy. Clinicians and researchers can improve attendance by addressing modifiable characteristics and increasing education on diabetic retinopathy and the importance of eye health in people with diabetes.

Abstract
OBJECTIVE To investigate the role of miR-10b in the proliferation and apoptosis of acute myeloid leukemia (AML), and to explore the underlying mechanism. PATIENTS AND METHODS The expression level of miR-10b in clinical AML cases and cell lines was detected by quantitative reverse transcription polymerase chain reaction (qRT-PCR). The interaction between miR-10b and homeobox D10 (HOXD10) was confirmed by qRT-PCR, Western blotting and Luciferase assay. The effect of miR-10b on biological functions of AML cell line (HL60) was analyzed in vitro. MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assay and colony formation assay were used to detect the proliferation and colony formation ability of AML cells, respectively. Meanwhile, flow cytometry and TUNEL staining were applied to measure cell cycle and apoptosis of AML cells, respectively. RESULTS miR-10b was significantly up-regulated in AML cases and cell lines. The potential target genes of miR-10b were analyzed by three public databases. Results showed that HOXD10 was a direct target of miR-10b. QRT-PCR, Western blotting and luciferase assay confirmed the regulatory effect of miR-10b on HOXD10. Overexpression of miR-10b accelerated the proliferation and colony formation ability of AML cells. Meanwhile, miR-10b overexpression decreased the percentage of AML cells in the G0/G1 phase when compared with S phase, and suppressed the apoptosis of AML cells. However, the addition of HOXD10 could reverse the effects of miR-10b. CONCLUSIONS MiR-10b could regulate the proliferation, colony formation, cell cycle and apoptosis of AML cells through targeting HOXD10, indicating that miR-10b might be a potential therapeutic target for the treatment of AML.

Abstract
Accumulating evidence has demonstrated that the aberrant expression of microRNAs (miRs or miRNAs) may contribute to the initiation and progression of various types of human cancer and may also constitute biomarkers for cancer diagnosis and therapy. However, the specific function of miR‐9 in hepatocellular carcinoma (HCC) remains unclear, and the mechanisms that underlie HCC are incompletely understood. Here, we report that miR‐9 expression was significantly decreased in clinical tumor tissue samples, as well as in a cohort of HCC cell lines. In addition, it was demonstrated that overexpression of miR‐9 suppressed the proliferative and migratory capacity of HCC cells and impaired cell cycle progression. Furthermore, high mobility group AT‐hook 2 (HMGA2) was verified as a downstream target gene of miR‐9 using a luciferase reporter assay. Quantitative RT‐PCR and western blotting implicated HMGA2 in the miR‐9‐mediated reduction of HCC cell growth. In vivo, transfection with miR‐9 mimics down‐regulated the expression of HMGA2, thus leading to a dramatic reduction in tumor growth in a mouse xenograft model. These results suggest that miR‐9 may exert critical antitumor effects on HCC by directly targeting HMGA2, and the miR9/HMGA2 signaling pathway may be of use for the diagnosis and prognosis of patients with HCC.

Abstract
The quantum criticality of an Ising-like screw chain antiferromagnet SrCo_{2}V_{2}O_{8}, with a transverse magnetic field applied along the crystalline a axis, is investigated by ultralow temperature NMR measurements. The Néel temperature is rapidly and continuously suppressed by the field, giving rise to a quantum critical point (QCP) at H_{C_{1}}≈7.03 T. Surprisingly, a second QCP at H_{C_{2}}≈7.7 T featured with gapless excitations is resolved from both the double-peak structure of the field-dependent spin-lattice relaxation rate 1/^{51}T_{1} at low temperatures and the weakly temperature-dependent 1/^{51}T_{1} at this field. Our data, combined with numerical calculations, suggest that the induced effective staggered transverse field significantly lowers the critical fields, and leads to an exposed QCP at H_{C_{2}}, which belongs to the one-dimensional transverse-field Ising universality.

Abstract
The present research was major in investigating the regulation association among hsa_circ_0101432 (has_circ_RPPH1), miR-1258, miR-622 and MAPK1 in hepatocellular carcinoma (HCC), and we explored the mechanism underlying pathogenesis of HCC. Microarray analysis was employed to detect hsa_circ_0101432 expression in HCC. Hsa_circ_0101432 was verified as a circRNA by testing divergent primers and RNase R. And qRT-PCR was performed to determine the expression of hsa_circ_0101432, miR-1258, miR-622 and MAPK1 mRNA. Furthermore, miRanda predicted that mRNAs targeted miR-1258 and miR-622. CCK-8 assay, colony formation assay, flow cytometry as well as transwell assay were performed to detect cell viability, proliferation, apoptosis and invasive ability, respectively. Xenograft in nude mice was applied to observe tumor growth in vivo. Up-regulated hsa_circ_0101432 and down-regulated miR-1258 and miR-622 were detected in HCC while Hsa_circ_0101432 enhanced expression of MAPK1 mRNA by targeting miR-1258 and miR-622. Knocking down hsa_circ_0101432 or overexpressing miR-1258 and miR-622 inhibited proliferation and invasive ability of HCC cell and promoted cell apoptosis. Hsa_circ_0101432 was confirmed to promote tumor growth via inhibiting miR-1258 and miR-622 expression and promoting MAPK1 mRNA expression by in vivo experiment. Hsa_circ_0101432 inhibited HCC cell apoptosis, promoted cell proliferation, invasive ability and HCC tumor growth by targeting miR-1258 and miR-622 and upregulating MAPK1 mRNA expression.

Abstract
Objective: To compare the etiology and incidence of pulmonary infection in patients with esophageal carcinoma accompanied by esophagotracheal fistula before and after the airway stent implantation. Methods: The clinical records of patients with esophageal carcinoma accompanied by esophagotracheal fistula in Respiratory Department and Oncology Department of Meitan General Hospital were retrospectively analyzed from March 2008 to January 2018. The demographic data, comorbidities, pathological results and etiology were collected before and after tracheal stents were implanted in all patients. The incidence of pulmonary infection was analyzed, and the classification of etiology was compared before and after tracheal stents implantation. Results: A total of 100 patients were included in the study. The incidence rate of pulmonary infection before stents implantation was 83.0%. A total of 105 bacterial strains were cultured, including 73 strains of gram-negative bacteria (69.5%) and mainly pseudomonas aeruginosa, 5 strains of gram-positive bacteria [all methicillin-resistant staphylococcus aureus (MRSA)] (4.8%), and 27 strains of fungi (25.7%) and mainly candida albicans. The incidence rate of pulmonary infection was lowered to 53.0% after tracheal stents implantation (χ(2)=29.102, P<0.001). A total of 79 bacterial strains were cultured, and the main bacteria were still gram-negative bacteria and fungi, in which pseudomonas aeruginosa and candida albicans accounted for the majority. However, 13 strains of MRSA were cultured (16.5%), significantly higher than those before stents implantation (χ(2)=7.451, P=0.005). Conclusions: The incidence rate of pulmonary infection in patients with esophageal carcinoma accompanied by esophagotracheal fistula is very high. Gram-negative bacteria and fungi are the main etiologies. Tracheal stents implantation can effectively reduce the incidence of pulmonary infection. However, the incidence rate of MRSA is significantly increased after stents implantation.

Abstract
In Taiwan, an outbreak of acute hepatitis A (AHA) infection has been identified since June 2015. Approximately half of the cases occurred in HIV-infected men who have sex with men (MSM). We used the Taiwan Centers for Disease Control (TCDC)-operated National Disease Surveillance Systems (NDSS) to identify the incidence of AHA during 2011-2016. Between June 2015 and December 2016, a total of 1268 AHA cases were documented, and 601 cases (47.4%) were co-infected with HIV; the majority of whom were MSM (98.4%). Each AHA case was matched to two HIV-infected controls without AHA reported in the NDSS on age (± 5 years), risk factor of HIV infection, HIV diagnosis date (± 30 days) and county/city of residence at HIV diagnosis. Three hundred forty-three HIV/AHA cases were matched to 686 controls. In multivariable conditional logistic regression analysis, a previous gonorrhoea (adjusted OR=1.77, 95% CI 1.16-2.70) and recent (aOR=6.77, 95% CI 4.34-10.55) or remote syphilis report (aOR=3.56, 95% CI 2.48-5.13) were independently associated with AHA. The epidemic persisted till December 2016, and the cases with a new diagnosis of HIV infection after AHA (28/301, 9.3%) increased after July 2016 (P = .001). HIV/AHA cases were centralized in northern and central metropolitan areas and HIV-infected MSM with a recent history of sexually transmitted diseases in Taiwan. We recommend surveillance of associated behavioural and virologic characteristics and HAV counselling and testing for HIV-infected men.

Abstract
BACKGROUND AND OBJECTIVE Hepatocellular carcinoma (HCC) is the second leading cause of cancer death worldwide. Genotoxic stress resistance in patients often contributes to poor clinical outcomes, and is intensively associated to the upregulation of Nrf2/ARE signaling pathway. In this study, we examined the connection between the anticancer activity of two novel indazolo[3,2-b]quinazolinone (IQ) derivatives, IQ-7 and IQ-12, and their effect on the Nrf2/ARE signaling pathway. METHODS We initially measured the cytotoxicity of IQ-7 and IQ-12 in Hep3B (human hepatoma cell) and HL-7702 (normal human liver cell) cell lines, then further detected their effects on Nrf2/ARE signaling pathway and apoptosis. RESULTS IQ-7 and IQ-12 downregulated the expression levels of Nrf2 and its downstream target genes, such as NQO1, HO-1 and Gclc. In Hep3B cells treated with IQ-7 or IQ-12, the mitochondrial membrane potential decreased dramatically while the expression level of the pro-apoptotic protein VDAC1 and anti-apoptotic protein Bcl-2 significantly increased and decreased, respectively. In addition, IQ-7 (but not IQ-12) also induced the activity of Caspase-3. Interestingly, IQ-7 appeared to selectively inhibit Hep3B cells while having rare adverse effect on HL-7702 cells. CONCLUSION The two compounds were shown to induce apoptosis and inhibit the Nrf2/ARE signaling pathway in Hep3B cells, and IQ-7 was suggested a degree of specificity against cancer cells. The design of these compounds may therefore represent a new strategy for designing quinazoline derivatives that could selectively target carcinoma cells.

Abstract
Background At present, Da Vinci robotic assisted hepatectomy has been routinely carried out in conditional units. But there is no report concerning the use of Da Vinci robots for hepatic hydatid cystectomy and experience on this aspect is seldom mentioned before. This study was to summarize the preliminary experience in laparoscopic resection of hepatic hydatidectocyst with the Da Vinci Surgical System (DVSS). Case presentation A 29-year-old female diagnosed as hepatic hydatid in the right anterior lobe of liver was treated with laparoscopic resection by the DVSS under general anesthesia. Appropriate disposal of tumor cell in vascular system and disinfection of surgical field with hypertonic saline were conducted. The hepatic hydatidectocyst was resected completely with an operation time of 130 min, an intraoperative blood loss of 200 ml and a length of hospital stay for five days. The vital signs of patient were stable and no cyst fluid allergy occurred after operation. Conclusions Our result showed that laparoscopic resection of hepatic hydatidectocyst by using the DVSS is safe and feasible on the basis of hospitals have rich experience in treatment of cystic echinococcosisliver, resection with DVSS and laparoscopic excision.

Abstract
Background The objective of this paper is to analyze the role of bone marrow-derived mesenchymal stem cells (BM-MSCs) on the differentiation of T follicular helper (Tfh) cells in lupus-prone mice. Methods Bone marrow cells were isolated from C57BL/6 (B6) mice and cultured in vitro, and surface markers were identified by flow cytometry. Naïve CD4+ T cells, splenocytes and Tfh cells were isolated from B6 mice spleens and co-cultured with BM-MSCs. The proliferation and the differentiation of CD4+ T cells and Tfh cells were analyzed by flow cytometry. Lupus-prone MRL/Mp-lpr/lpr (MRL/lpr) mice were treated via intravenous injection with expanded BM-MSCs, the differentiation of Tfh cells was detected, and the relief of lupus nephritis was analyzed. Results MSCs could be successfully induced from bone marrow cells, and cultured BM-MSCs could inhibit T cell proliferation dose-dependently. BM-MSCs could prevent Tfh cell development from naïve CD4+ T cells and splenocytes. BM-MSCs could inhibit IL-21 gene expression and cytokine production and inhibit isolated Tfh cells and STAT3 phosphorylation. In vivo study proved that BM-MSCs intravenous injection could effectively inhibit Tfh cell expansion and IL-21 production, alleviate lupus nephritis, and prolong the survival rate of lupus-prone mice. Conclusions BM-MSCs could effectively inhibit the differentiation of Tfh cells both in vitro and in vivo. BM-MSC treatment could relieve lupus nephritis, which indicates that BM-MSCs might be a promising therapeutic method for the treatment of SLE.

Abstract
Objective: To compare the therapeutic efficiency and safety of radiofrequency catheter ablation (RFCA) for paroxysmal ventricular tachycardia (PSVT) guided by three-dimensional navigation with X-ray. Methods: One hundred and seventy-six patients with PSVT hospitalized in Department of Cardiology, Zhejiang Provincial People's Hospital between January 2013 and December 2014 were enrolled in this study. RFCA was performed on 95 patients (Group A) guided by the three dimensional electric-field navigation system (NavX) and the procedures were done with the spatial localization method, unless X-ray was needed in some cases.Eighty-one patients (Group B) underwent RFCA guided by X-ray only.The success rate, complications, recurrence rate, operation time, and X-ray exposure were compared between the two groups. Results: The immediate success rate of operation was 100% in the 176 PSVT patients without complications.There were recurrences in 2 cases of Group A, while in 1 case of Group B. The average operation time in Group A was (97±20) min, while (91±26) min in Group B. The median X-ray fluoroscopy time was 3.0 min and radiation dose was 18.5 μGym2 in Group A, which were significantly reduced compared with those in Group B (34.5 min, 167.3 μGym2) (P<0.05). There was no significant difference in immediate procedure success rate, complications, recurrence, and operative time between this two groups (P>0.05). Conclusions: The RFCA for PSVT guided by three-dimensional navigation is safe and feasible in the experienced electrophysiological center.Most patients suffer less or no X-ray radiation.
