Abstract
Objective: To investigate and verify a novel acute graft versus host disease (aGVHD) prevention protocol in the context of haploidentical hematopoietic stem cell transplantation (haplo-HSCT) . Methods: Patients who underwent haplo-HSCT in our center between January 2022 and December 2022 were included. All patients received reduced doses of cyclophosphamide, Rabbit anti-human tymoglobulin, ruxolitinib, methotrexate, cyclosporine, and MMF to prevent aGVHD. The transplantation outcomes, complications, and survival rate of all patients were investigated. Results: A total of 52 patients with haplo-HSCT were enrolled, 29 (55.8%) male and 23 (44.2%) female, with a median age of 28 (5-59) years. There were 25 cases of acute myeloid leukemia, 17 cases of acute lymphocyte leukemia, 6 cases of myelodysplastic syndrome, 2 cases of chronic myeloid leukemia and 2 cases of myeloproliferative neoplasms. 98.1% of patients had successful engraftment. The incidence of Ⅱ-Ⅳ aGVHD and Ⅲ-Ⅳ aGVHD was 19.2% (95% CI 8.2% -30.3% ) and 7.7% (95% CI 0.2% -15.2% ), respectively. No patients experienced severe gastrointestinal mucositis. The Epstein-Barr virus and CMV reactivation rates were 40.4% and 21.3%, respectively. 9.6% of patients relapsed during followup, with 1-year overall survival, progression-free survival, and non-relapse mortality rates of 86.5% (95% CI 76.9% -96.1% ), 78.8% (95% CI 67.4% -90.3% ) and 11.5% (95% CI 2.6% -20.5% ), respectively. Conclusion: Ruxolitinib combined with a low dose of PTCY is a safe and effective first-line aGVHD prevention strategy.

Abstract
Objective: To explore the significance of triggering receptor expressed on myeloid cells-2 (TREM-2) prognostic evaluation so as to provide novel biological markers in clinical practice for patients with hepatitis B virus-related acute-on-chronic liver failure ( HBV-ACLF). Methods: The research subjects of this study were divided into an experimental group and a control group. Fifty HBV-ACLF cases admitted to the Department of Infectious Diseases of the First Affiliated Hospital of Nanchang University from January 1, 2019 to December 31, 2019 were selected as the experimental group. Patients were divided into survival and death groups according to the actual prognosis at discharge (self-discharge and dead patients were considered death groups, and all enrolled patients were hospitalized for more than 28 days). Twenty-five healthy subjects were chosen as the control group. Peripheral venous blood was collected from the experimental group and the control group. Plasma and peripheral blood mononuclear cells (PBMC) were isolated. The concentrations of TREM-2, interleukin (IL)-6, and IL-8 were detected in the plasma. TREM-2 mRNA expression was detected in PBMC. A single blood sample was collected from the control group, whereas five blood samples were dynamically collected from the experimental group on the day of admittance and at 7, 14, 21, and 28 days after treatment commenced. Simultaneously, upon admission, the relevant clinical indicators of HBV-ACLF patients were monitored, including the liver function test: alanine aminotransferase, aspartate aminotransferase, total bilirubin, albumin, coagulation function test: international normalized ratio, prothrombin time, and other indicators. Measurement data were expressed as mean±standard deviation (x±s). Count data were compared and analyzed using the χ(2) test. The intra-group factor mean was compared using a repeated measures ANOVA. The means were analyzed by t-tests between the two groups. Bivariate correlation analysis was used to analyze the correlation between the two variables. The value of TREM-2 as a diagnostic marker was analyzed using the receiver operating characteristic (ROC) curve. Results: The mRNA expression of TREM-2 in the PBMC of HBV-ACLF patients showed a gradually increasing trend at various time points and was significantly higher in the survival group than that of the control group at 28 days (P < 0.01), while the death group showed a gradually weakening trend at various time points and was significantly lower than the control group at 28 days (P < 0.01). (1) The levels of TREM-2 in the plasma of HBV-ACLF patients generally showed a gradually increasing trend at various time points in the survival group. The levels on the day of admission and 7, 14, 21, and 28 days after the initiation of treatment were (1.49±0.85), (1.62±0.58), (1.95±0.69), (2.33±0.71), and (2.00±0.67) ng/ml, respectively. The expression of TREM-2 in the death group showed a gradually weakening trend at various time points. The levels on the day of admission and 7, 14, 21, and 28 days after initiation of treatment were (1.40±0.73), (1.59±0.79), (1.56±0.80), (1.05±0.49), and (0.81±0.21) ng/ml, respectively. The survival group's various detection time points were higher than those of the death group, and the difference was statistically significant. The plasma level of TREM-2 in the healthy control group was (1.25±0.35) ng/ml. (2) The concentrations of IL-6 and IL-8 in the plasma of HBV-ACLF patients showed a gradually decreasing trend at various time points in the survival group. The levels on the day of admission and 7, 14, 21, and 28 days after initiation of treatment were (46.70±26.31), (33.98±20.28), (19.07±10.24), (14.76±7.84), (9.12±7.65) and (108.29±47.07), (93.85±26.53), (79.27±34.63), (56.72 ±18.30), (37.81±13.88) pg/ml, respectively. However, its concentration in the death group fluctuated within a relatively high range. The levels on the day of admission and 7, 14, 21, and 28 days after the initiation of treatment were (41.94±24.19), (36.99±19.78), (34.30±20.62), (34.14±14.52), (36.64±23.61) and (104.65±50.16), (112.98±45.03), (118.43±45.00), (111.67±40.44), (109.55±27.54) pg/ml, respectively. (3) Bivariate correlation analysis results indicated that the plasma TREM-2 content was negatively correlated with the plasma levels of pro-inflammatory cytokines IL-6 and IL-8 (r = -0.224, P = 0.025; r = - 0.223, P = 0.026). ROC curve analysis showed that the mRNA levels of TREM-2 in PBMCs at various time points for prognostic evaluation of HBV-ACLF patients were 1d=0.667, 7d=0.757, 14d=0.979, 21d=0.986, and 28d= 0.993. The areas under the ROC curve of the TREM-2 content in the plasma at various time points were 1d=0.522, 7d=0.571, 14d=0.658, 21d=0.927, and 28d=0.994. Conclusion: TREM-2 mRNA expression in PBMC and TREM-2 content in plasma have a significant relationship to the prognosis of HBV-ACLF patients and may inhibit the liver inflammatory response by regulating the secretion of pro-inflammatory cytokines IL-6 and IL-8. Dynamic monitoring of TREM-2 expression in peripheral blood is favorable for evaluating the prognostic condition of HBV-ACLF patients.

Abstract
PURPOSE/OBJECTIVE(S) The neoadjuvant chemoradiotherapy combined with surgery has become the standard treatment model for operable locally advanced esophageal cancer. This present study was aimed to explore the feasibility and safety of neoadjuvant chemoradiotherapy combined with nimotuzumab and camrelizumab in initially inoperable patients with locally advanced esophageal cancer (NCT0535168). MATERIALS/METHODS Patients with initially inoperable locally advanced esophageal cancer were enrolled. All patients were supposed to receive neoadjuvant chemoradiotherapy (40.85-41.4Gy/19-23f plus albumin paclitaxel (0.05g qw) and cisplatin (30mg qw)). The nimotuzumab (EGFR antibody targeting extracellular domain) was administrated 200mg weekly and the camrelizumab was taken 200mg every 3 weeks. The primary endpoints were safety and the surgical conversion rate. The second endpoints were pathological response, 1, 2 and 3-years disease free survival, and alteration of the immune microenvironment after neoadjuvant therapy. RESULTS From December 2021 to now, 20 initially inoperable patients with locally advanced esophageal cancer were enrolled in this study, including 16 males and 4 females. The median age was 65 years. 19 patients were squamous cell carcinoma, and 1 patient was adenocarcinoma. The surgical conversion rate was 70% (14/20). The pathological complete response rate was 35.7% (5/14). The main AEs were radiation esophagitis and hematological toxicity. 4 patients developed over Grade III myelosuppression (3 for Grade Ⅲ (15%) and 1 for Grade Ⅳ (5%). 1(5%) patient developed Grade III atopic dermatitis. No patients died or with disease progression in patients who underwent surgery up to now. Compare to pre-treatment baseline, CD8+T cell and IFN-γ were significantly increased, IL-8 was significantly decreased in peripheral blood after neoadjuvant therapy. CONCLUSION The neoadjuvant chemoradiotherapy combined with nimotuzumab and camrelizumab was with high surgical conversion rate and acceptable safety in initially inoperable patients with locally advanced esophageal cancer.

Abstract
Objective: To analyze the clinical characteristics of leptomeningeal metastasis (LM) patients from epithelial growth factor receptor (EGFR)-mutated lung adenocarcinoma, and their impacts on the survival of the patients. Methods: From July 2018 to July 2022, the clinicopathological data of 81 patients diagnosed as EGFR-mutated lung adenocarcinoma LM by cytopathology who admitted to the Department of Oncology of Xiangya Hospital of Central South University were retrospectively analyzed, including 33 males and 48 females. The age ranged from 31 to 76 years, with a median age of 54 years. All the 81 patients were followed up, with a median follow-up of 21.0 months (95%CI: 12.5 to 29.5 months). The Kaplan Meier method was used to draw survival curve. Cox proportional hazards regression model was used to analyze the impact of the factors on the survival of patients. Results: Among the 81 patients, the interval between the initial diagnosis of lung cancer and the pathological diagnosis of LM in cerebrospinal fluid (CSF) was 0-108 months, with a median interval of 14 months. Fifty-two patients (64.2%) used the third-generation epithelial growth factor receptor tyrosine kinase inhibitor (EGFR-TKIs), while 17 patients (21.0%) used EGFR-TKIs in combination with other drugs, and 12 patients (14.8%) were treated with best supportive care (BSC). Sixty patients (74.1%) had a Kanofsky performance status (KPS) score of less than 60 points, and 71 patients (87.7%) had brain parenchymal metastasis and/or spinal metastasis. Twenty-two patients (27.2%) used pemetrexed through intrathecal CSF, and 17 patients (21.0%) used pemetrexed through the Ommaya sac to the CSF of the ventricle. The incidence of adverse event related to the administration of pemetrexed through CSF was 64.1% (25/39), mainly manifested as myelosuppression, including 22 patients of leukocyte reduction, 25 patients of hemoglobin reduction, and 14 patients of platelet reduction. The median post-leptomeningeal metastasis overall survival (pLM-OS) in 81 patients was 11.0 (95%CI: 7.7-14.3) months. KPS score≥60 points (HR=0.407, 95%CI: 0.170-0.973, P=0.043), CSF cytology negative after treatment (vs persistent positive, HR=0.351, 95%CI: 0.155-0.792, P=0.012), intraventricular administration of pemetrexed (vs non intraventricular administration of pemetrexed, HR=0.319, 95%CI: 0.137-0.745, P=0.008) and the treatment with third-generation EGFR-TKIs after LM (vs EGFR-TKIs in combination with other drugs, HR=0.486, 95%CI: 0.237-0.998, P=0.049) were a factor affecting pLM-OS of patients. Conclusions: Brain parenchyma, or/and spine are the most sites where the LM patients concurrently metastasize. KPS score≥60 points and CSF cytology negative after treatment, intraventricular administration of pemetrexed and the treatment with third-generation EGFR-TKIs are indictors affecting pLM-OS of the patients.

Abstract
OBJECTIVES Antibiotic therapy is widely used for patients with community-acquired pneumonia (CAP), and yet whether the efficacy of antibiotics differs based on the treatment mode remains unclear. This study aimed to summarize the evidence regarding the efficacy and safety of oral vs. parenteral administration of antibiotic therapy for the treatment of patients with CAP. METHODS The databases of PubMed, EmBase, and the Cochrane Central Register of Controlled Trials were systematically searched for eligible randomized controlled trials (RCTs) from inception until 11 December 2021. The effectiveness of oral vs. parenteral administration of antibiotic therapy was estimated using a random-effects model. Additional sensitivity, subgroup, and publication bias analyses were performed. RESULTS Of 912 identified articles, 12 RCTs involving 2158 patients with CAP were included in our pooled analysis. This mostly included trials with low certainty and some concerns regarding risk of bias, including lack of allocation concealment and blinding of participants and personnel. Overall, oral antibiotic therapy did not affect the incidence of clinical success at the end of treatment (relative risk [RR], 1.01; 95% confidence interval [CI], 0.98-1.05; P = 0.417), clinical success at follow-up (RR, 1.02; 95% CI, 0.98-1.06; P = 0.301), or adverse events (RR, 0.87; 95% CI, 0.56-1.35; P = 0.527). Moreover, oral antibiotic therapy had a beneficial effect on the risk of all-cause mortality (RR, 0.58; 95% CI, 0.35-0.96; P = 0.034). CONCLUSIONS Oral administration of antibiotics is associated with a reduced risk of all-cause mortality compared with parenteral therapy based on RCTs with low to moderate quality. This finding should be verified in further large-scale RCTs.

Abstract
Objective: To investigate the possible pathophysiological mechanism of laryngopharyngeal reflux (LPR) in the development of lingual tonsil hypertrophy (LTH). Methods: The lingual tonsil tissues were collected from 73 patients [48 males and 25 females, aged from 24 to 76 (52.86±12.04) years] who underwent surgery for laryngopharyngeal diseases at the Department of Otolaryngology and Head and Neck Surgery, Southern Hospital of Southern Medical University from October 2019 to December 2020, and the lingual tonsil grade (LTG), reflux symptom index (RSI) and reflux finding score (RFS) were assessed. The expression of pepsin in LTH was detected by immunohistochemistry. The coexpression of pepsin and macrophages were detected by immunohistofluorescence. In vitro, cytological experiments and pathway assays were performed on macrophages stimulated by pepsin. Pathway alterations of macrophages in pepsin-positive high-grade LTH were detected by double-fluorescence immunohistochemistry. Data were analyzed by SPSS 20.0 software. Results: There were 44 clinically significant LPRD patients with LTG 3 and 4, and the pepsin positive rate was 88.6% (39/44). While, the pepsin positive rate of LTG 1 and 2 was 48.3% (14/29). LTG was significantly positively correlated with RFS/RSI positive rate(χ2=23.01/19.62, P<0.001/0.001; r=0.54/0.51, P<0.001/0.001) and pepsin tissue staining intensity (H=21.58, P<0.001; r=0.53, P<0.001), respectively. Pepsin and macrophages were clearly colocalized in high grade LTH. In vitro, pepsin promoted macrophage proliferation (P<0.05) and production of IL-6/IL-8 (P<0.05). Pepsin significantly up-regulated the p38/JNK MAPK pathway in macrophages (P<0.05). Pepsin up-regulated the expression of IL-6 and IL-8 of macrophages by activating the p38 MAPK pathway (P<0.05), and up-regulated the expression of IL-8 by activating the JNK pathway (P<0.05). The p38/JNK MAPK pathways were highly expressed in macrophages of pepsin-positive LTH (P<0.05). Conclusions: LPR is an important pathogenic factor in LTH. Macrophages may mediate pepsin-induced inflammation and the pathogenesis of LTH.

Abstract
Objective: To explore the safety and feasibility of stereotactic radiation therapy (SBRT) strategy for irradiating porcine ventricular septum, see if can provide a preliminary experimental evidence for clinical SBRT in patients with hypertrophic obstructive cardiomyopathy (HOCM). Methods: Five male pigs (39-49 kg, 6 months old) were used in this study. Pigs were irradiated at doses of 25 Gy (n=2) or 40 Gy (n=3). Delineation of the target volume was achieved under the guidance of 3-dimensional CT image reconstruction, and SBRT was then performed on defined target volume of porcine ventricular septum. Blood biomarkers, electrocardiogram and echocardiography parameters were monitored before and after SBRT. Pathological examination (HE staining, Masson staining) was performed on the target and non-target myocardium at 6 months post SBRT. Results: SBRT was successful and all animals survived to the designed study endpoint (6 months) after SBRT. Serum cardiac troponin T (cTnT) level was significantly higher than the baseline level at 1 day post SBRT, and reduced at 1 week after SBRT, but was still higher than the baseline level(P<0.05). Serum N-terminal pro-B type natriuretic peptide (NT-proBNP) was also significantly increased at 1 day post SBRT (P<0.05) and returned to baseline level at 1 week post SBRT. The serum NT-proBNP level was (249±78), (594±37) and (234±46) pg/ml, respectively, and the cTnT was (14±7), (240±40) and (46±34) pg/ml, respectively at baseline, 1 day and 1 week after SBRT in the 40 Gy dose group. The serum NT-proBNP level was (184±20), (451±49) and (209±36) pg/ml, respectively, the cTnT values were (9±1), (176±29) and (89±27) pg/ml, respectively at baseline, 1 day and 1 week after SBRT in the 25 Gy dose group. Both NT-proBNP and cTnT values tended to be higher post SBRT in the 40 Gy dose group as compared with the 25 Gy dose group, but the difference was not statistically significant (P>0.05). The left ventricular ejection fraction and the left ventricular end-diastolic diameter remained unchanged before and after SBRT (P>0.05). The interventricular septum thickness showed a decreasing trend at 6 months after SBRT, but the difference was not statistically significant ((9.54±0.24) mm vs. (9.82±8.00) mm, P>0.05). The flow velocity of the left ventricular outflow tract, and the valve function and morphology were not affected by SBRT. At 6 months after SBRT, HE staining revealed necrosis in the irradiated target area of the myocardium in the 40 Gy dose group and the 25 Gy dose group, and the degree of necrosis in the irradiated interventricular septum was more obvious in the 40 Gy dose group as compared with the 25 Gy group. The combined histological analysis of the two groups showed that the necrotic area of the irradiated target area accounted for (26±9)% of the entire interventricular septum area, which was higher than that of the non-irradiated area (0) (P<0.05). There was no damage or necrosis of myocardial tissue outside the target irradiation area in both groups. The results of Masson staining showed that the percentage area of myocardial fibrosis was significantly higher in the irradiated target area than non-irradiated area ((12.6±5.3)% vs. (2.5±0.8)%, P<0.05). Conclusion: SBRT is safe and feasible for irradiating porcine ventricular septum.

Abstract
Large benign hepatic masses as a rare indication for liver transplantation have been reported less frequently. These liver transplantations are complex, with high intraoperative bleeding, high perioperative complication rates, and high mortality rates due to difficulties in visualization, especially when they have undergone various percutaneous operations or open surgery, resulting in severe perihepatic adhesions. Here is a case report of a patient admitted to our hospital who underwent liver transplantation after suffering from a giant hemangioma in liver transplantation for 10 years and who had received multiple interventional treatments ineffective in the past.

Abstract
BACKGROUND This study aimed to identify preoperative and postoperative risk factors of venous thromboembolism (VTE) after gastrectomy in gastric cancer (GC) patients. METHODS 757 GC patients underwent gastrectomy at our institution and 246 patients with elevated postoperative D-dimer levels who received Doppler ultrasonography of lower/upper extremity veins were enrolled. Clinicopathological factors data were collected, and the differences in clinicopathological factors between postoperative VTE (+) and VTE (-) groups were analyzed. Univariate and multivariate logistic regression analyses were performed to identify independent risk factors of postgastrectomy VTE. RESULTS Of 246 patients with elevated postgastrectomy D-dimer concentrations, 74 patients showed thrombosis in lower/upper extremity veins. Among preoperative factors, age, WBC level, D-dimer concentration, and blood glucose level were significantly higher in the postoperative VTE (+) group. Among the postoperative factors, hemoglobin level was significantly lower in the postoperative VTE (+) group. Among the pathological factors, tumor stage, depth of invasion and TNM classification indicated higher malignancy in the postoperative VTE (+) group. Univariate logistic regression analysis indicated age, preoperative blood glucose level, postoperative hemoglobin level, tumor stage, depth of invasion, and TNM classification as the independent risk factors for postgastrectomy VTE, whereas multivariate logistic regression analysis revealed age and tumor stage as independent risk factors for postgastrectomy VTE. CONCLUSION Our study revealed that age, preoperative blood glucose level, postoperative anemia, and tumor malignancy were independent risk factors for GC patients exhibiting postgastrectomy VTE. Therefore, the perioperative monitoring, assessment and management of risk factors are important in achieving better outcomes after gastrectomy.

Abstract
Background The principal objective of this project was to investigate the Epidermal Growth Factor Receptor (EGFR) gene mutation characteristics of lung cancer patients, which can provide a molecular basis for explaining the clinicopathological features, epidemiology and use of targeted therapy in lung cancer patients in the coal-producing areas of East Yunnan. Methodology We collected 864 pathologically confirmed lung cancer patients’ specimens in First People’s Hospital of Qujing City of Yunnan Province from September 2016 to September 2021. We thereafter employed Next Generation Sequencing (NGS) technology to detect all exons present in the EGFR gene. Results The overall mutation frequency of the EGFR gene was 47.22%. The frequency of EGFR gene mutations in the tissue, plasma, and cytology samples were found to be 53.40%, 23.33%, and 62.50%, respectively. Univariate analysis indicated that the coal-producing areas and Fuyuan county origin were significantly associated with relatively low EGFR gene mutation frequency. Female, non-smoking history, adenocarcinoma, non-brain metastasis, and tissue specimens were found to be related to high EGFR gene mutation frequency. Multivariate logistic regression analysis suggested the lung cancer patients in the central area of Qujing City, stage Ia, non-coal-producing areas, non-Fuyuan origin, and non-Xuanwei origin were more likely to develop EGFR gene mutations. The most common mutations were L858R point mutation (33.09%) and exon 19 deletion (19-del) (21.32%). Interestingly, the mutation frequency of G719X (p = 0.001) and G719X + S768I (p = 0.000) in the coal-producing areas were noted to be more significant than those in non-coal-producing regions. Conclusion This findings of this study might be important in establishing the correlation between routine using NGS for EGFR gene mutation diagnosis and clinical practice in the lung cancer patients.

Abstract
Objective: To explore the predictive value of the impedance measured during leadless pacemaker Micra implantation on the trend of changes of pacing threshold post implantation. Methods: This is a retrospective cross-sectional study. Patients who received implantation of leadless pacemaker Micra at the Second Xiangya Hospital of Central South University from December 2019 to August 2020 were enrolled. The clinical data and the intraoperative electrical parameters during leadless pacemaker implantation were collected. The impedance and pacing threshold data were analyzed at three time points: immediate release, 5-10 min after release, and after traction test. Receiver operating characteristic (ROC) curves and the area under the curve (AUC) were used to analyze the value of the impedance at immediate release on predicting the trend of changes of pacing threshold post implantation. Results: A total of 21 patients (mean age: (72.2±12.5) years, 12 males) were included. The impedance of 21 patients was (798.1±35.3) Ω immediately after implantation, (800.9±35.6) Ω after 5-10 minutes of release, and (883.6±31.7) Ω after traction test. Impedance was similar between the three time points (P>0.05). The threshold was (0.97±0.11) V/0.24 ms immediately after implantation, (0.95±0.12) V/0.24 ms at 5-10 min after the release, and (0.59±0.06) V/0.24 ms after the traction test. The threshold was significantly lower after the traction test than that immediately after release (P=0.003) and than that at 5-10 minutes after release (P=0.008), suggesting a decreased tendency of the threshold over time. According to the analysis of the ROC curve, the immediate impedance after the release ≥680 Ω could predict the ideal pacing threshold after the traction test (AUC=0.989, 95%CI 0.702-0.964, P<0.001), the prediction sensitivity was 87%, and the specificity was 100%. The pacing threshold would be not ideal with the immediate impedance ≤ 520 Ω (95%CI 0.893-1.000, P<0.001), the sensitivity was 100%, and the specificity was 80%. Conclusions: The impedance immediately after the release has predictive value for the changing trend of threshold post leadless pacemaker Micra implantation. Impedance ≥680 Ω immediately after release is often related with ideal pacing threshold after the traction test. In contrast, the impedance ≤ 520 Ω pacing is often related with unsatisfactory threshold after the traction test, therefore, it is recommended to find a new pacing site to achieve the impedance ≥680 Ω immediately after release during leadless pacemaker Micra implantation.

Abstract
The Wilson-Cowan model can emulate gamma oscillations, and thus is extensively used to research the generation of gamma oscillations closely related to cognitive functions. Previous studies have revealed that excitatory and inhibitory inputs to the model can modulate its gamma oscillations. Inhibitory and excitatory self-feedback loops are important structural features of the model, however, its functional role in the regulation of gamma oscillations in the model is still unclear. In the present study, bifurcation analysis and spectrum analysis are employed to elucidate the regulating mechanism of gamma oscillations underlined by the inhibitory and excitatory self-feedback loops, especially how the two self-feedback loops cooperate to generate the gamma oscillations and regulate the oscillation frequency. The present results reveal that, on one hand, the inhibitory self-feedback loop is not conducive to the generation of gamma oscillations, and increased inhibitory self-feedback strength facilitates the enhancement of the oscillation frequency. On the other hand, the excitatory self-feedback loop promotes the generation of gamma oscillations, and increased excitatory self-feedback strength leads to the decrease of oscillation frequency. Finally, theoretical analysis is conducted to provide explain on how the two self-feedback loops play a crucial role in the generation and regulation of neural oscillations in the model. To sum up, Inhibitory and excitatory self-feedback loops play a complementary role in generating and regulating the gamma oscillation in Wilson-Cowan model, and cooperate to bidirectionally regulate the gamma-oscillation frequency in a more flexible manner. These results might provide testable hypotheses for future experimental research.

Abstract
Ischaemic stroke is a common condition leading to human disability and death. Previous studies have shown that oleanolic acid (OA) ameliorates oxidative injury and cerebral ischaemic damage, and miR-186-5p is verified to be elevated in serum from ischaemic stroke patients. Herein, we investigated whether OA regulates miR-186-5p expression to control neuroglobin (Ngb) levels, thereby inhibiting neuronal pyroptosis in ischaemic stroke. Three concentrations of OA (0.5, 2, or 8 μM) were added to primary hippocampal neurons subjected to oxygen–glucose deprivation/reperfusion (OGD/R), a cell model of ischaemic stroke. We found that OA treatment markedly inhibited pyroptosis. qRT–PCR and western blot revealed that OA suppressed the expression of pyroptosis-associated genes. Furthermore, OA inhibited LDH and proinflammatory cytokine release. In addition, miR-186-5p was downregulated while Ngb was upregulated in OA-treated OGD/R neurons. MiR-186-5p knockdown repressed OGD/R-induced pyroptosis and suppressed LDH and inflammatory cytokine release. In addition, a dual luciferase reporter assay confirmed that miR-186-5p directly targeted Ngb. OA reduced miR-186-5p to regulate Ngb levels, thereby inhibiting pyroptosis in both OGD/R-treated neurons and MCAO mice. In conclusion, OA alleviates pyroptosis in vivo and in vitro by downregulating miR-186-5p and upregulating Ngb expression, which provides a novel theoretical basis illustrating that OA can be considered a drug for ischaemic stroke.

Abstract
A coordination polymer with dual functions of high proton conductivity and highly sensitive fluorescent sensors demonstrates a great application potential. In this work, a cadmium-based coordination polymer (denoted as CP 1) with hydrothermal stability was synthesized. The abundant coordination water, lattice water, and amino groups make an extended hydrogen-bonding pathway for efficient proton migration, which endows CP 1 with the highest proton conductivity of 2.41 × 10-3 S·cm-1 at 353 K and 98% RH. Especially, the proton conductivity of the chitosan (CS) hybrid membrane containing CP 1 reaches a maximum value of 2.62 × 10-2 S·cm-1 under 343 K and 98% RH, which increases almost 7 times higher than that of the pure CS membrane due to the host-guest collaboration. Furthermore, luminescence studies revealed that CP 1 is a high-sensitivity and good-selectivity fluorescent probe for the detection of trace amounts of l-histidine with a lowest detection limit of 1.0 × 10-8 M.

Abstract
Isoquercitrin (ISO), an extract from Chinese traditional herb, exhibits potent neuroprotective roles in various disease models. However, its role in stroke is not fully understood. We established oxygen-glucose deprivation and reoxygenation (OGD/R) model in SH-SY5Y cell to study the roles of ISO in stroke. In the experiment, the changes of LDH level and cell viability (MTT) were analyzed. Apoptotic cells stained with anti-Annexin V antibody and propidium iodide (PI) were detected by flow cytometry. The mRNA and protein level of aldolase C (ALDOC) and nuclear factor erythroid 2-related factor (Nrf2) was determined by real-time quantitative polymerase chain reaction (qPCR) and Western blotting assay, respectively. The localization of Nrf2 was investigated by immunofluorescent assay. OGD/R reduced cell viability via inducing cell apoptosis, while ISO treatment reduced the level of apoptosis in OGD/R-treated SH-SY5Y cells ISO rescued OGD/R-treated cells. Mechanistically, the expression of Nrf2 and ALDOC was upregulated upon ISO treatment, while knockdown of ALDOC diminished the activation of autophagy and hence inhibited ISO-mediated protective activity. We further demonstrated that ISO enhanced ALDOC transcription by promoting nuclear translocation of Nrf2, and suppression of Nrf2 decreased the expression of ALDOC. Our data revealed that ISO exhibited neuroprotective activity in OGD/R model through Nrf2-ALDOC-autopagy axis and highlighted the potential application of ISO in stroke treatment.

Abstract
UNLABELLED China is a middle-risk country for hip fracture at present, which differs from previous data that it was low-risk. By 2050, the total number of hip fractures in people older than 65 years is predicted to be 1.3 million. INTRODUCTION To assess hip fracture incidence in China and examine the heterogeneity of hip fracture in seven geographical regions of China. METHODS There were 238,230 hip fracture patients aged 65 years or older from 2013 to 2016 from a large national in-patients database (HQMS) involving 30.6 million hospitalizations. Taking into account the total national hospitalization rate per calendar year, we estimated the incidence of hip fracture per 100,000 residents older than 65 years in China overall and in seven geographical Chinese regions. RESULTS The proportion of men and women older than 65 years with hip fractures was 1.00:1.95. Between 2013 and 2016, the number of hip fractures per 100,000 people age 65+ was 278. China has vast territories; the number of hip fractures per 100,000 people over 65 years old was 202 in Northeast China and 374 in Northwest China. Northwest has higher altitude, lower population density, is less developed with lower urbanization than Northeast China which is low altitude, and highly urbanized. CONCLUSIONS China should no longer be regarded as a low-risk country for hip fracture. By 2050, the total number of hip fractures in people older than 65 years in China is predicted to be 1.3 million. Higher altitude areas had higher hip fracture rates than lower altitude, higher urbanized areas.

Abstract
Objective: To study the relationship between serum HBV pgRNA and antigen status in patients with chronic hepatitis B treated with long-term nucleotide analogues, and to elucidate the reason and possible mechanism of high relapse rate in antiviral therapy of nucleotide analogues in chronic hepatitis B. Methods: 94 patients with chronic hepatitis B who had been treated with long-term antiviral therapy with nucleotide analogues (more than 2 years) were divided into 5 groups according to their HBeAg and HBsAg levels: e antigen positive group(group1), e antigen negative and HBsAg > 1 500 IU/L group(group2), e antigen negative and 100 IU/L< HBsAg < 1 500 IU/L group(group3), e antigen negative and HBsAg < 100 IU/L group(group4), e antigen negative and HBsAg negative group(group5). The level and detection rate of HBVpgRNA in different antigen states groups were analyzed and compared. In addition, in order to exclude the influence of other factors on the results of this study. The study was divided into groups according to age, gender and treatment time. Results: The detection rate of HBVpgRNA was 95.0% in patients with e antigen positive, while 43.2% in patients with e antigen seroconversion, which was significantly lower than that in patients with e antigen positive (P < 0.05). The detection rate of serum HBVpgRNA was 95.0% in e antigen positive group, 75.0% in group 2, 65.0% in e antigen negative with group 3, 15.0% in group 4 and 0% in group 5. Among them, group 1, group 2 and group 3 was significantly higher than that in group 4 and group 5. There was significant difference between the two groups (P < 0.05). However, there was no difference in the positive rate of serum HBV pgRNA among group 1, group 2 and group 3 (P > 0.05). Similarly, there was no difference in the positive rate of serum HBV pgRNA between group 4 and group 5 (P > 0.05). Moreover, the detection rate of serum HBV pgRNA was not correlated with age, gender and treatment time of nucleotide analogues (P > 0.05). Conclusion: There is a significant correlation between the serological antigen status and the presence of HBV pgRNA in chronic hepatitis B after long-term treatment of nucleotide analogues. The persistence of HBV pgRNA is closely related to the low seroconversion rate of e antigen and the high level of HBsAg. HBV pgRNA can be used as one of the biomarkers to judge the transcription activity and replication status of HBV cccDNA in liver.

Abstract
Yellow tea, a rare type tea from China, has a rich breadth of functional ingredients and benefits the gastrointestinal tract. However, it is not clear whether the yellow tea extract can alleviate constipation. Therefore, we used loperamide-induced constipation in mice to evaluate the effects of yellow tea extract. Fifty Kunming mice were randomly divided into five groups: normal, model, low-dose yellow tea extract, low-dose yellow tea extract prevention group, and high-dose yellow tea extract prevention group. Mice were administered yellow tea extract for 5 weeks followed by loperamide-induced constipation for the final 2 weeks. The results showed that yellow tea extract alleviated constipation symptoms by improving the fecal water content, defecation weight, and gastrointestinal transit rate. Yellow tea extract intervention also protected colon tissue, regulated serum neurotransmitters, and decreased the vasoactive intestinal peptide level. Furthermore, qRT-PCR indicated that yellow tea extract regulated genes associated with the constipation state, raised 5-HT3 and 5-HT4 and reduced AQP3 and AQP4 mRNA expression. Moreover, we found that yellow tea extract changed the gut microbiota composition. Community diversity and richness were increased and principal co-ordinate analysis demonstrated that the yellow tea extract prophylaxis groups differed from the model group. Difference analysis indicated that yellow tea extract increased Roseburia, Lachnospiraceae_UCG-006, and Bifidobacterium and decreased norank_f_Clostridiales_vadinBB60_group, unclassified_o_Bacteroidales, and Bacteroides, which are correlated with constipation. Based on these results, we believe that regular yellow tea consumption can effectively alleviate constipation.

Abstract
Indium-based chalcogenide semiconductors have been served as the promising candidates for solar H2 evolution reaction, however, the related studies are still in its infancy and the enhancement of efficiency remains a grand challenge. Here, we report that the photocatalytic H2 evolution activity of quantized indium chalcogenide semiconductors could be dramatically aroused by the co-decoration of transition metal Zn and Cu. Different from the traditional metal ion doping strategies which only focus on narrowing bandgap for robust visible light harvesting, the conduction and valence band are coordinately regulated to realize the bandgap narrowing and the raising of thermodynamic driving force for proton reduction, simultaneously. Therefore, the as-prepared noble metal-free Cu0.4-ZnIn2S4 quantum dots (QDs) exhibits extraordinary activity for photocatalytic H2 evolution. Under optimal conditions, the Cu0.4-ZnIn2S4 QDs could produce H2 with the rate of 144.4 μmol h−1 mg−1, 480-fold and 6-fold higher than that of pristine In2S3 QDs and Cu-doped In2S3 QDs counterparts respectively, which is even comparable with the state-of-the-art cadmium chalcogenides QDs.

Abstract
Migraine with brainstem aura (MBA) accompanied by disorders of consciousness (DOC) is a rare subtype of migraine. The pathophysiology of MBA with DOC has not been elucidated yet. Some patients have a family history of migraine, and women are more affected than men. The aura symptoms are diverse; however, when MBA is combined with DOC, the clinical manifestations are more complicated. Coma is the most common clinical manifestation. The overall duration of the patient’s DOC is short and can often return to normal within half an hour. Headache often occurs after regaining consciousness and can also occur at the same time as DOC. The most common headache is located at the occipital region. Although DOC is reversible, considering the current small number of cases, we still need to improve our understanding of the disease to avoid misdiagnosis. The MBA patient’s electroencephalogram and cerebral blood flow perfusion may have transient changes and may return to normal in the interictal period or after the DOC. Although triptans have traditionally been contraindicated in MBA under drug instructions, the evidence of basilar artery constriction, as postulated in MBA, is lacking. Lasmiditan is currently the first and only 5-HT 1F receptor agonist approved by the Food and Drug Administration. The calcitonin gene-related peptide receptor antagonists and monoclonal antibody therapies may be the most promising for future consideration. Here, the pathophysiology, clinical manifestations, diagnostic tools, and treatment progress for MBA with DOC are reviewed.

Abstract
Hair-fin anchovy (Setipinna tenuifilis) is an economically important fish distributed in the West Indian Ocean and the Northwest Pacific Ocean. In this study, 154 individuals in eight populations of S. tenuifilis were sequenced and 850 million raw reads were obtained using restriction site-associated DNA sequencing (RAD-seq). First, we identified 14 012 044 hypothetical SNP markers. A dataset of 199 903 high-quality SNPs was collected after further screening. These SNPs have a strong ability to test the genetic diversity between the eight populations. The differentiation and genetic law between samples were explored based on SNPs in populations of S. tenuifilis. The results of this study will provide data for protecting the genetic resources of the species.

Abstract
Objective: To investigate the consistency of Velum, Oropharygneal, Tongue base, Epiglottis (VOTE) scores between two surgeons with similar clinical experience in obstructive sleep apnea hypopnea syndrome (OSAHS) patients with different degree of disease, and to analyze the influencing factors leading to the difference in score. Methods: This was a cross-sectional study. 64 preoperative drug-induced sleep endoscopy (DISE) videos of OSAHS patients during December 2014 to July 2018, from Nanfang Hospital, Southern Medical University were analyzed. The VOTE score was assessed single-blind by two similar experienced surgeons, and the Kappa value between the two scorers was calculated by the third researcher. According to the characteristics of the case, Fisher's exact test or chi-square test method was used to further explore the factors that influenced the consistency. Results: Sixty-four patients were divided into four groups according to the severity of the disease, including mild (7 cases), moderate (30 cases), severe(18 cases), and extremely severe (9 cases). The scores evaluated between two researchers were analysed for consistency. For mild patients, the two scorers were completely consistent in the configuration and degree of obstruction in the velum and epiglottis (Kappa=1). There was no agreement on whether obstruction or not, obstructed configuration, obstructed degree of the oropharynx and tongue base, and presence of velum and epiglottis obstruction. For moderate patients, the two scorers had a good consistency in the configuration and degree of the velum (0.61≤Kappa≤0.80), and there was no consistency in the evaluation of the degree of tongue base and epiglottis (P>0.05). The consistency of the remaining obstructed conditions in the four planes was generally or moderate (0.21≤Kappa≤0.60). For patients with severe OSAHS, the two raters were completely consistent in the evaluation of palatopharyngeal and epiglottic planes for the presence of obstruction, but there was no consistency in the degree of obstruction. Although the degree of obstruction in the oropharyngeal plane can be assessed with good consistency, the consistency of whether the plane was blocked or not was generally not high. In the assessment of other obstructive conditions in the four planes of severe patients, the agreement between the two scorers was moderate or generally. For extremely severe patients, the two scorers were completely consistent in the evaluation of the velum obstruction, but there was no consistency in the degree of obstruction of the oropharynx and tongue base, and the obstruction configuration and degree of the epiglottis. The evaluation of other obstructed conditions in the four planes is good or moderate. Among the patients with severe OSAHS, the difference in the assessment of obstruction of the oropharynx was associated with tonsil size (P<0.05). Conclusion: When physicians with similar clinical experience scored VOTE, the consistency of whether the velum and oropharyngeal planes are obstructed is related to the severity of the disease. Better consistency is observed among more severe OSAHS patients. The reason for the poor consistency of the oropharyngeal plane in severe OSAHS patients OSAHS is due to the difference of the tonsils size. For severe OSAHS patients with small tonsils, the assessment of whether the oropharynx is obstructed should be more cautious.

Abstract
Objective: To investigate and analyze the current situation, screening, clinical characteristics, prevention and treatment of bleeding esophageal varices in cirrhotic patients with portal hypertension in Tibet region. Methods: Clinical data of cirrhotic patients with portal hypertension through March 2017 to February 2020 from Tibet region were collected and analyzed retrospectively. Results: 511 cases with liver cirrhosis were included in the study, of which 185 cases (36.20%) had compensated cirrhosis and 326 cases (63.80%) had decompensated cirrhosis. Further analysis of the etiological data of liver cirrhosis showed that 306 cases (59.88%) were of chronic hepatitis B, 113 cases (22.11%) of alcoholic liver disease, and 68 cases (13.31%) of chronic hepatitis B combined with alcoholic liver disease. Among patients with compensated liver cirrhosis, 48 cases (25.95%) underwent endoscopic examination of which 33 diagnosed as high-risk variceal bleeding. However, none of these 33 cases had received non-selective β-blocker therapy, and only four patients had received endoscopic variceal banding therapy. Among patients with decompensated liver cirrhosis, 83 cases (25.46%) had a history of upper gastrointestinal bleeding, 297 cases (91.10%) had ascites, 23 cases (7.05%) had hepatic encephalopathy, and 3 cases (0.92%) had hepatorenal syndrome. Among the patients with a history of upper gastrointestinal bleeding, 42 cases (50.60%) had received secondary preventive treatment for bleeding esophageal varices, including 39 cases of endoscopic treatment, 1 case of endoscopic combined drug treatment, 3 cases of interventional treatment, and 2 cases of surgical treatment. Conclusion: Chronic hepatitis B and alcoholic liver diseases are the main causes of liver cirrhosis in Tibet region. Moreover, this region lacks screening, prevention and treatment for bleeding esophageal varices in cirrhotic patients with portal hypertension. Therefore, it is necessary to increase the screening of high-risk groups to prevent and improve the first-time bleeding, and promote multidisciplinary team to prevent and treat re-bleeding.

Abstract
According to the monitoring data of pollutant concentration in the Xiaoqing River estuary from 2008 to 2017, 13 pollutants affecting water quality were selected. The trends of changes in water quality were identified mainly by the pollution index method, and the driving factors affecting water quality changes were quantitatively and qualitatively analyzed by the Spearman and Pearson correlation analysis method and the principal component analysis. The results showed that the water quality of the Xiaoqing River estuary was improved and the pollution was greatly reduced from 2008 to 2017. The pollution factors were still above the limits to varying degrees; COD and petroleum were the most serious pollutants, TP came second, and the remaining pollutants basically met the water quality standards of the Ⅲ. The pollution degree of petroleum, COD, NH4+-N, NO2--N, and As showed an overall downward trend, and the pollution degree of TP, NO3--N, Cu, Pb, Zn, Cd, Hg, and Cr6+ showed an upward trend to different degrees. Social and economic factors were the main driving factors affecting the water quality of the Xiaoqing River. The discharge of pollutants and the changes in land use type led to serious water pollution overall in the Xiaoqing River, whereas the improvement of sewage treatment rate and the implementation of water environmental protection policy were the main factors affecting the water quality improvement of the Xiaoqing River. Natural factors were the secondary driving factors affecting the water quality of the Xiaoqing River. Climate and hydrological factors, such as temperature, sunshine duration, precipitation, and instantaneous runoff, also indirectly affected the water quality to different degrees.

Abstract
Several bioactive molecules isolated from the saliva of blood-sucking arthropods, such as mosquitoes, have been shown to exhibit potential anticoagulant function. We have previously identified a 30kDa allergen named Aegyptin-like protein (alALP), which is highly homologous to Aegyptin, from the salivary glands of female Aedes albopictus (Asian tiger mosquito). In this study, we identified the conserved functional domain of alALP by using bioinformatic tools, and expressed the His-tagged alALP recombinant protein in sf9 insect cells by generation and transfection of a baculoviral expression plasmid carrying the fulllength cDNA of alALP. We purified this recombinant protein and examined its function on the inhibition of blood coagulation. The results showed that the purified His-alALP prolonged the Activated Partial Thromboplastin Time (APTT), Prothrombin Time (PT) and Thrombin Time (TT) in vitro as well as the Bleeding Time (BT) in vivo, which suggest that alALP could be a novel anticoagulant.

Abstract
Objective:To investigate the effect of Notch1 gene on radiosensitivity of nasopharyngeal carcinoma cells and its molecular mechanism. Method:A Notch1-knockout CNE-2 cell line was constructed using CRISPR/Cas9 system, and the expression of Notch1 gene was detected by RT-PCR and Western blot. After treatment with different doses of radiation, the survival fraction (SF) of each group was calculated, and used the GraphPad Prism 6.0 software and the Linear quadratic model were used to calculate the fitted dose survival curve and the sensitivity enhancement ratio(SER). Taking 6 Gy as radiation dose, the experiment was divided into four groups: Notch1(+) group, Notch1(-) group, IR+Notch1(+) group and IR+Notch1(-) group. CCK-8 assay was used to detect cell proliferation in each group. Annexin V-FITC/PI double staining assay was used to detect the changes of apoptosis in each group. The expression of H2AX, CyclinD1, Bax, Bcl-2 and GAPDH proteins were detected by Western blot. Result:The CNE-2 cell line with Notch1 gene knockout was successfully constructed. The clonogenic assay showed knockout of Notch1 enhanced the radiosensitivity of NPC cells. The CCK-8 assay showed that cell proliferation and cell viability were significantly reduced in the IR+Notch1(-) group compared with the IR+Notch1(+) group(P<0.05). Annexin V-FITC/PI double staining assay showed that the IR+Notch1(-) group had the highest apoptosis rate compared with the other groups (P<0.05). Western blotting demonstrated that the expression of γH2AX was significantly increased after irradiation of Notch1 nasopharyngeal carcinoma cells, the expression of Cyclin-D1 was increased, and the ratio of Bax:Bcl-2 was higher. Conclusion:Knockout of Notch1 signaling molecule can effectively improve the radiosensitivity of NPC cells cultured in vitro, which may be a potential target for radiosensitization of NPC.

Abstract
Objective:To analyze the related factors of VOTE score for drug-induced endoscopy(DISE) in patients with obstructive sleep apnea (OSA). Method:Fifty-four OSA patients, diagnosed by polysomnograph, underwent surgical treatment from Nov 2014 to Dec 2016 in our hospital. All patients underwent drug induced sleep endoscope, and then the collapse of pharyngeal space was evaluated. We analyzed the related factors with VOTE score. Result:The occlusion rates were significant statistical different in different spaces of 54 OSA patients undergoing DISE(P=0.000, velum 98.15%, oropharynx 81.48%, tongue base 40.47%, and epiglottis 11.11% respectively). The rateand of tongue base collapsing was related with Mallampatis(P<0.05) and Friedman stage(P<0.05). The VOTE score was weakly related with Friedman stage(r=0.297, P<0.05), medium related with BMI(r=0.376, P<0.05), AHI(r=0.312, P<0.05) and lowest SpO2(r=0.376, P<0.01). Conclusion:In the VOTE scoring system for DISE, the rate of collapse in tongue base was related with Mallampatis and Friedman stage. The VOTE score was medium related with BMI, AHI and Lowest SpO2, mild related with Friedman stage.

Abstract
Objective:To evaluate the effect of surgery on olfactory function in patients with chronic rhinosinusitis with nasal polyps(CRSwNP) by subjective and objective olfactory tests. Method:This was a retrospective study. Forty patients with CRSwNP who underwent endoscopic sinus surgery(ESS) from 2015 to 2017 in Beijing Anzhen Hospital were enrolled. Postoperative time was 6-46 months. The patients were followed up in October 2018 and examined using Sniffin' sticks olfactory test and olfactory event-related potentials (oERP). The polyps collected during surgery were performed to eosinophil count and percentage calculation. They were divided into eosinophilic CRSwNP(ECRS) and non-eosinophilic CRSwNP(NECRS). The subjective and objective olfactory functions between the two groups were compared before and after surgery respectively and the paired T test was performed between the postoperative and the preoperative Sniffin' sticks olfactory test. Covariance analysis was used to adjust the effect of different postoperative time on postoperative olfactory recovery. Result:There were 21(52.5%) ECRS and 19(47.5%) NECRS patients of the 40 patients with nasal polyps. There was statistical difference in the posterior ethmoid score and the posterior olfactory cleft score of CT. According to the criterion of total TDI increased more than 5.5, olfactory function in 21(52.5%) patients had improved. In addition, there was a significant improvement in olfactory function in ECRS group either in unilateral T/TDI or bilateral T/D/TDI, but only unilateral T/TDI increased in NECRS group. There was no significant difference in Sniffin' sticks olfactory test between the two groups, but there was a statistically significant difference in the latency of oERP after surgery. Conclusion:ESS could improve olfactory function in patients with CRSwNP by more than 50%. Bilateral olfactory improvement in ECRS was better than that in NECRS, but olfactory function in postoperative ECRS was still lower than that in NECRS. oERP can more objectively and accurately reflect the severity of olfactory disorders associated with eosinophilic inflammation.

Objective: To assess the current evidence regarding the efficacy, safety, and potential advantages of endoscopic compared with open salvage surgery for patients with local recurrent nasopharyngeal carcinoma. Methods: A systematic search of Pubmed/Medline, Embase, and Cochrane databases ranged between 2000 and 2017 was conducted. Included studies reported specific residual or local recurrent nasopharyngeal cancer survival data. Proportional Meta-analysis was performed on both outcomes with a random-effects model and the 95% confidential intervals were calculated by Stata 12.0 software. Results: A total of 24 case series studies were included in the Meta-analysis.The pooled 2-year overall survival rates of endoscopic and open group were 84% (95%CI:72%-93%), 68%(95%CI:59%-77%),respectively.The pooled 2-year disease-free survival rates of endoscopic and open group were 68%(95%CI:53%-81%), 65%(95%CI:54%-75%),respectively. The pooled 5-year overall survival rates of endoscopic and open group were 72%(95%CI:37%-97%), 48% (95%CI:40%-56%),respectively.The pooled 5-year disease-free survival rates of endoscopic and open group were 65%(95%CI:29%-93%), 50%(95%CI:43%-57%),respectively.The combined outcome of endoscopic was higher than open procedure. In addition, less severe complications, lower local recurrence rates(27%vs32%).The 2-year overall survival rates of endoscopic was higher than open procedure in the staging of rT1, rT2, and rT3 (93%vs87%; 77%vs63%; 67%vs53%) , but was equal to open in the staging for rT4 (35%vs35%) .Meta-regression showed that the heterogeneity was correlated with advanced tumor ratio. Conclusions: The present Meta-analysis reveals that endoscopic approach offers a safe and efficient alternative to open approach with better short-term outcome and fewer postoperative complications in selecting patients strictly.

Abstract
Objective: To investigate the association between single nucleotide polymorphisms (SNP) of IL-17A (rs2275913) and IL-17F (rs763780) genes and susceptibility to knee osteoarthritis (KOA) in Chinese Han and Tibetan populations. Methods: A case-control study was conducted. Total of 122 Han KOA patients and 124 Han healthy controls and 76 Tibetan KOA patients and 68 Tibetan healthy controls in Qinghai Province were selected between 2015 and 2017. SNP typing was performed on four groups of rs2275913 and rs763780 polymorphisms by polymerease chain reaction (PCR)-sequencing to detect IL-17A and IL-17 F genotype frequencies and allele frequencies. The t test was used to compare data between groups. Results: The genotype AA frequency of IL-17A (rs2275913) was significantly different between the Han KOA and the control group (OR=2.625, P=0.016). Compared with the frequency of allele A in healthy control group, the allele A frequency in Han KOA group was significantly higher(OR=1.445, P=0.047); the genotype frequency of IL-17A,however,was comparable between the KOA and the healthy control in Tibetan population (OR=1.696, 1.355, both P>0.05); there were also not difference in the IL-17F (rs763780) genotype frequency and allele frequency between the Han KOA and Tibetan KOA groups and two control groups,respectively (OR=1.346, 1.126, both P>0.05). Conclusion: It is highly likely that the pathogenesis of KOA in Chinese Han population is positively related to the genotype AA and allele A of IL-17A (rs2275913).

Abstract
N,N-Dimethylformamide hydrochloric acid/XMCln ([HDMF]Cl/XMCln, M = Zn or Fe, n = 2 or 3) was synthesized by stirring the mixture of [HDMF]Cl and metal chloride. [HDMF]Cl-based DES was characterized by FT-IR spectroscopy, ESI-MS and 1H-NMR spectroscopy. The oxidative desulfurization activity was investigated using [HDMF]Cl/0.2FeCl3 and [HDMF]Cl/ZnCl2 as the extractant and catalyst, and hydrogen peroxide (H2O2) as the oxidant. The desulfurization rate can reach up to 98.08% and 99.2% for DBT using [HDMF]Cl/0.2FeCl3 and [HDMF]Cl/ZnCl2, respectively. After recycling for 7 times, the removal rate of DBT still can reach more than 97%. [HDMF]Cl/XMCln exhibits high desulfurization activity. Meanwhile, the DES saving a lot of N,N-dimethylformamide protects environment.![]()

Abstract
Objective: To explore the function and role of innate lymphoid cells in the pathogenesis of systemic lupus erythematosus (SLE) at different disease activity levels. Methods: From Nov 2017 to May 2018, 40 patients with SLE and 15 age-matched healthy non-immune-related diseases controls were enrolled from Anhui provincial hospital. According to the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI)-2K, the patients were divided into active group (n=20) and remission group (n=20). The frequency of ILCs, B cells, CD4+T and CD8+T cells from peripheral blood mononuclear cells (PBMCs) was detected by flow cytometry. The subsets of ILCs in each group were compared with the subsets of B cells and T cell respectively. The levels of IL-4, IL-33 and IFN-γ in each group were tested by ELISA. Result: Compared with the control group, ILC1 percentage was significantly increased in SLE active group [(22.33%±2.52%) vs (14.56%±1.28%), P=0.018 1]; ILC2 percentage was decreased significantly in both remission group [(19.67%±1.83%) vs (42.48%±3.46%), P<0.000 1] and active group [(8.67%±0.83%) vs (19.67%±1.83%), P<0.000 1]; ILC3 percentage was decreased significantly in active group [(5.72%±1.08%) vs (14.35%±2.40%), P=0.001 3]. SLEDAI score was negatively correlated with the percentage of ILC2 (P=0.023 9) in all patients. The percentage of ILCs in the remission group (P=0.046 2) and activity group (P=0.003 7) were both increased significantly. Moreover, the percentage of ILC2 in active group was negatively correlated with CD4+T cells (P=0.030 8), and the serum IgG was negatively correlated with ILC2% in all patients (P=0.013 8). Compared with control group or remission group, the levels of IFN-γ (F=10.91, P=0.000 1) and IL-4 (F=6.046, P=0.004 7) in active group were remarkable higher. However, IL-33 was significantly reduced in active group (F=6.645, P=0.002 7). The percentage of ILC2 (r=0.154 3, P=0.028 8) and ILC3 (r=0.313 6, P=0.001 1) in all patients with SLE were positively correlated with the level of IL-4. Conclusion: The percentage of ILCs is related to disease activity, and ILCs play a "double-edged" role in the pathogenesis of SLE. Its function and mechanism are worth further exploration.

Abstract
This study was carried out to determine the pathogen-causing diarrhoea in sheep Ovis aries in the Qinghai Tibetan Plateau Area, China. A trophozoite was identified as species of ciliate alveolates infecting the sheep based on morphological characteristics examined by microscope. It was mostly spherical, colourless and transparent, with many vesicles. Macronucleus and contractile vacuoles could not be distinguished. Size of the trophozoite was 80–180×70–150 μm and its surface was covered with cilia. Molecular analysis based on sequences of 18S rRNA and ITS genes confirmed the ciliate species as Balantidium coli. According to the literature, there have been many epidemiological investigations of B. coli infection in pigs, monkeys and humans. To our knowledge, this was the first report of B. coli infections in sheep in the Qinghai Tibetan Plateau Area of China, or eleswhere around the world. Importantly, the sheep case was rare but raised our concern that B. coli may spread across species and expand its host range.

Abstract
Objective: To investigate the normal urinary manganese value in healthy adults in Guangxi, China and its distribution characteristics. Methods: From 2015 to 2016, stratified random sampling based on age and sex was performed to select 1533 healthy adults aged 18-60 years in Nanning,Liuzhou,Guilin,Hezhou,Wuzhou,Yulin,Guigang,Beihai,Qinzhou,Laibin,Hechi Nandan,Bose Jingxi,Chongzuo Daxin,and Fangchenggang.All of them had no history of occupational manganese exposure or acute or chronic liver/renal diseases and had lived in the local area for more than one year. A total of 1417 urine samples with normal specific gravity and complete data were obtained, and graphite furnace atomic absorption spectrometry was used to measure urinary manganese.The distribution characteristics of urinary manganese level were analyzed among adults with different ages,sexes,or presence or absence of smoking habits or among those who lived or did not live in the mining area. Results: The geometric mean of urinary manganese among healthy adults in Guangxi was 0.52 μg/L,and the upper limit of normal was 5.68μg/L. There was no significant difference in urinary manganese level between the healthy adults with different ages, sexes,or presence or absence of smoking habits (P>0.05).The healthy adults who lived in the mining area of nonferrous metal mines had a significantly higher geometric mean of urinary manganese than those who did not live in such areas(1.65μg/Lvs0.34μg/L,P<0.01). Conclusion: The upper limit of normal of urinary manganese is 5.68 μg/L among healthy adults in Guangxi,and the healthy adults who live in the mining area of manganese mine or nonferrous metal mines have a significantly higher urinary manganese level than those who do not live in such areas.

Abstract
Objective:To discuss the correlation between adenoid hypertrophy and laryngopharyngeal reflux in children, and to determine the accuracy of reflux symptom index(RSI) and reflux finding score(RFS) in predicting adenoid hypertrophy and laryngopharyngeal reflux(LPR). Method:Assessment of RSI and RFS was performed in 71 children with adenoid hypertrophy who underwent surgery.The adenoid biopsy specimens were examined by pepsin immunohistochemical staining. According to the positive results of pepsin staining to evaluate the sensitivity and specificity of RSI and RFS to predict LPR. Result:Among the 71 children with adenoid hypertrophy, RSI was greater than 13 points in 4 cases (5.63%), RFS was greater than 7 points in 26 cases (36.62%), and 1(1.41%) was positive in both scores. Pepsin expression was detected in 52 cases of adenoid hypertrophy tissues, with a total positive rate of 73.24% (52/71),most were strong positive(15/71,21.13%)and positive(23/71,32.39%). The higher the adenoid hypertrophy grade, the higher the expression level of pepsin (r=0.476, P<0.01).Define the positive rate of pepsin as the gold standard for the diagnosis of LPR, the sensitivity and specificity of RSI and RFS were 5.77%,34.62% and 94.74%,57.89% respectively. Pepsin staining intensity was positively correlated with troublesome or annoying cough(r=0.356, P=0.002)and was negatively correlated with ventricular obliteration(r=-0.212,P=0.038). Conclusion:There is a correlation between adenoid hypertrophy and LPR in children,LPR plays an important role in the development of adenoid and the role and mechanism of pepsin in adenoid hypertrophy needs further studyAs the low sensitivity of RSI and RFS, it is not suitable for the screening of adenoid hypertrophy in children with LPR. Children with adenoid hypertrophy cough for a long time and the laryngoscopy shows the ventricular obliteration, the presence of LPR should be warned.

Abstract
Objective:To investigate the safety and validity of endoscopic sinus surgery in chronic rhinosinusitis patients receiving long-term oral warfarin.Method:Fifty-eight chronic rhinosinusitis patients receiving long-term oral warfarin were given low-molecular-weight heparin as a bridge therapy. Fifty-eight patients who did not take warfarin were selected as the control group. The intraoperative bleeding volume, operation time, incidence of thrombosis and recurrence rate of sinusitis were observed.Result:The operation time and intraoperative bleeding volume of the experimental group were significantly higher than those of the control group. There were no significant differences of age,gender,thrombosis incidence, nd recurrence between the two groups.Conclusion:Low-molecular-weight heparin is safe and effective bridge therapy to have an endoscopic sinus surgery for the chronic rhinosinusitis patients receiving long-term oral warfarin.

Abstract
Objective: To explore age-based clinical and immune parameters in Henoch-Schönlein purpura (HSP) to determine clinically useful markers reflecting disease characteristic. Methods: A cohort of 502 patients with HSP were enrolled into this retrospective study to evaluate their clinical and immune data. Results: Majority HSP cases occurred at age ≤14 years and showed significant immune imbalances of ESR, CD3(+) cells, CD4(+) cells, CD3(-)CD16(+)CD56(+) cells, CD4(+)/CD8(+) cells, IgG, IgA, IgM, IgE, complements C3/C4 and ASO in the acute phase. Compared to patients aged >14 years, symptoms of joint were more frequent at disease onset in patients aged ≤14 years (20.8% vs 7.6%, χ(2)=13.547, P<0.001) , and involvement of digestive tract and joint were also more frequent (57.4% vs 33.8%, χ(2)=24.106, P<0.001; 55.9% vs 32.5%, χ(2)=23.768, P<0.001, respectively) , but not for involvement of kidney (21.4% vs 51.3%, χ(2)=42.440, P<0.001) . The patients aged ≤14 years had distinct immune state, reductions of CD3(+) cells, CD4(+) cells and IgG were more frequent than patients aged >14 years, also increase of ASO (33.1% vs 20.0%, χ(2)=6.656, P=0.010) , but not increase of IgA (2.6% vs 39.4%, χ(2)=15.582, P<0.001) . In addition, reduction of IgG and increase of IgE were positively associated with digestive tract involvement (P<0.001, P=0.001, respectively) , reduction of CD3(+)CD4(+) cells and normal IgM were positively associated with joint involvement (P=0.004, P=0.003, respectively) , increase of CD3(+)CD8(+) cells and normal CD3(+) cells were positively associated with kidney involvement (P=0.032, P=0.014, respectively) . Conclusion: HSP showed significant immune imbalance in the acute phase, patients between aged ≤14 and >14 years had distinct clinical and immune characteristic, and abnormal immune parameters were significantly associated with organ involvements.

Abstract
Objective: To investigate the effect of zinc finger E-box-binding homeobox 2 (ZEB2) on hepatitis B virus (HBV) replication and expression. Methods: HepG2, HepG2.2.15, and HepAD38 cells were cultured separately, and Western blot was used to measure the expression of ZEB2. HepG2.2.15 cells were cultured and transfected with ZEB2 expression plasmids or shRNA targeting ZEB2. Western blot was used to measure the expression of ZEB2 and HBV core proteins, quantitative real-time PCR was used to measure HBV 3.5 kb RNA and HBV DNA, Southern blot was used to measure HBV replicative intermediate, and ELISA was used to measure the expression of HBsAg and HBeAg, in order to clarify the effect of ZEB2 on HBV replication and expression. The dual-luciferase reporter system was used to analyze the effect of ZEB2 on HBV promoter, and the chromatin immunoprecipitation assay was used to detect the binding of ZEB2 to HBV promoter. The t-test was used for comparison of means between groups. Results: The expression of ZEB2 was inhibited in the cells with HBV replication. Overexpression of ZEB2 reduced the level of HBV replication and expression by about 50% (P< 0.05). After ZEB2 was downregulated by shZEB2-1 or shZEB2-2, the level of HBV replicative intermediate increased from 58.53 ± 3.43 to 112.80 ± 5.03, and 128.30 ± 2.31, the relative expression level of HBV 3.5 kb RNA increased from 1.00 ± 0.01 to 2.03 ± 0.02 and 2.32 ± 0.03, the level of HBsAg increased from 35.63% ± 1.57% to 81.87% ± 0.43% and 100.00% ± 2.18%, and HBeAg increased from 37.00% ± 0.70% to 88.00% ± 2.60% and 100.00% ± 0.75%. Furthermore, ZEB2 could bind to HBV core promoter and inhibit its transcriptional activity. Conclusion: ZEB2 inhibits HBV replication and expression through binding to HBV core promoter and inhibiting its transcriptional activity.

Abstract
Objective: To discuss the relationship between lingual tonsil hypertrophy and laryngopharyngeal reflux. Methods: Ninety-two patients who received throat surgery in Nanfang Hospital between October 2015 and October 2016 were enrolled. Twenty-six healthy volunteers were recruited as normal controls. All participants were assessed with the reflux finding score(RFS) and the size of lingual tonsils were evaluated using a clinical grading system proposed by Friedman under electronic laryngoscope. The score of reflux symptom index(RSI), personal history and medical history were gathered. Biopsy specimens of lingual tonsils were taken from all participants for the immunohistochemical stain of pepsin.SPSS 19.0 software was used for statistical analysis. Results: There were 46.2% (12/26) pepsin-positive and 53.8% (14/26) pepsin-negative volunteers in normal controls. There were 87.0% (80/92) pepsin-positive and 13.0% (12/92) pepsin-negative patients in study group. The severity of lingual tonsil hypertrophy and expression intensity of pepsin in patients were significantly higher in volunteers (Z=-3.636, Z=-5.273, P<0.01). The severity of lingual tonsil hypertrophy was positively associated with the pepsin level in patients (r=0.556, P<0.01). The patients with pepsin-positive expression showed significant correlation between lingual tonsil hypertrophy and the positive rate of RSI and RFS (r=0.258, r=0.225, P<0.05). Analysis of correlated factors indicated that lingual tonsil hypertrophy was associated with smoking (χ(2)=8.502, P<0.05). Conclusions: The expression of pepsin can be detected in lingual tonsil tissues. The lingual tonsil hypertrophy is closely related to laryngopharyngeal reflux.

Abstract
Objective:To compare the differences of the sites of airway obstruction in OSAHS patients between awake and sleep state by using the VOTE classification system. Method:Forty OSAHS patients diagnosed by PSG underwent awake Müller's maneuver and drug-induced sleep endoscopy (DISE). Video and compare the observation. Its findings were described using the VOTE classification system which include the following features: level, degree and configuration of obstruction. Associations were analyzed between different degrees of obstruction, BMI, AHI, minimal SaO₂ and average SaO₂. Result:Our patients had 52.5% complete velum collapse and 30.0% complete oropharyngeal lateral wall collapse in awake Müller's maneuver. In DISE, airway closure of 95.0% cases related to velum occurred collapse in concentric configuration, and 90.0% cases showed completely obstructive. We found that 60.0% complete oropharyngeal lateral wall collapse and 17.5% complete tongue base collapse. There was a significant difference in the VOTE scores between DISE and awake Müller's maneuver, and the VOTE scores of DISE were higher in all levels (P<0.05). No association was found between degrees of obstruction, AHI, BMI, minimal SaO2 and average SaO₂ in Müller's maneuver (P>0.05). Complete velum collapse was just significantly associated with AHI and minimal SaO₂ in DISE (P<0.05). Conclusion:The VOTE scores of DISE were higher than awake Müller's maneuver, reflected by more obstructive levels and severe degree. The difference between different degrees of obstruction, BMI, AHI, minimal SaO₂ and average SaO₂ was not significant.
