Objective To explore the role of breast/ovarian cancer susceptibility gene 1 associated protein 1(BAP1)in the occurrence and progression of human malignant glioma and the feasibility of BAP1 as a clinical diagnostic marker for malignant glioma.Methods The differential expression of BAP1 in normal and glioma tissue was analyzed based on the GSE4290 and GSE90598 sub-datasets from the gene expression omnibus(GEO)database.Receiver operating characteristic(ROC)curve analysis was conducted to assess the early diagnostic value of BAP1 for malignant glioma.Primary lesion tissues from 28 nonpaired malignant glioma patients and non-tumor brain tissues removed by internal decompression surgery in 5 patients with traumatic brain injury collected independently were collected,and the expression levels of BAP1 were measured using quantitative real-time polymerase chain reaction(qRT-PCR).Specific small interfering RNAs(siRNAs)targeting BAP1 were transiently transfected into U251 cells to further evaluate their interference efficiency.Flow cytometry was employed to analyze changes in the cell cycle and apoptosis of U251 cells with BAP1 knockdown.Results The results of bioinformatics showed that the expression of BAP1 in malignant glioma tissues was lower than that in normal brain tissues(GSE 4290:1 209±18.49 vs 1 476±53.90,GSE 90598:5.19±0.10 vs 5.65±0.21),and the differences were significant(t=5.115,2.267,all P<0.05).ROC curve showed that BAP1 could efficiently differentiate malignant glioma tissue from normal brain tissue(GSE4290:AUC=0.78,GSE90598:AUC=0.75,all P<0.05).The expression level of BAP1 in primary malignant glioma tissue was lower than that in normal brain tissue(0.27±0.04 vs 1.06±0.07),and the difference was significant(t=10.22,P<0.001).After down-regulating the expression of BAP1 in U251 cells,the proportion of S phase cells increased from 17.59%to 27.21%(siBAP1-1)and 25.79%(siBAP1-2),respectively,and the differences were significant(t=6.576,6.642,all P<0.01).However,the apoptosis levels decreased from 10.17%to 2.70%(siBAP-1)and 3.00%(siBAP-2),respectively,and the differences were significant(t=10.31,9.428,all P<0.01).Conclusion Histone H2A deubiquitinase BAP1 could exert the function of tumor suppressor genes by inhibiting rapid cell cycle progression and promoting apoptosis in malignant glioma,and could serve as a potential clinical diagnostic biomarker for malignant glioma.

Background/Aims:
Low educational attainment is a well-established risk factor for nonalcoholic fatty liver disease (NAFLD) in developed areas. However, the association between educational attainment and the risk of NAFLD is less clear in China.
Methods:
A cross-sectional study including over 200,000 Chinese adults across mainland China was conducted. Information on education level and lifestyle factors were obtained through standard questionnaires, while NAFLD and advanced fibrosis were diagnosed using validated formulas. Outcomes included the risk of NAFLD in the general population and high probability of fibrosis among patients with NAFLD. Logistic regression analysis was employed to estimate the risk of NAFLD and fibrosis across education levels. A causal mediation model was used to explore the potential mediators.
Results:
Comparing with those receiving primary school education, the multi-adjusted odds ratios (95% confidence intervals) for NAFLD were 1.28 (1.16 to 1.41) for men and 0.94 (0.89 to 0.99) for women with college education after accounting for body mass index. When considering waist circumference, the odds ratios (95% CIs) were 0.94 (0.86 to 1.04) for men and 0.88 (0.80 to 0.97) for women, respectively. The proportions mediated by general and central obesity were 51.00% and 68.04% for men, while for women the proportions were 48.58% and 32.58%, respectively. Furthermore, NAFLD patients with lower educational attainment showed an incremental increased risk of advanced fibrosis in both genders.
Conclusions
In China, a low education level was associated with a higher risk of prevalent NAFLD in women, as well as high probability of fibrosis in both genders.

Objective:To explore the effect of Helicobacter pylori(HP)eradication on development of metachronous gastric cancer(MGC)after endoscopic submucosal dissection(ESD)in elderly patients with early gastric cancer.Methods:From January 2014 to December 2019, 748 early gastric cancer patients aged 60 years or older, receiving ESD in Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School, were included.According to the situation of HP infection and eradication efficacy within 1 year postoperatively, patients were divided into three groups.The patients with HP infection and successful HP-eradication were enrolled into successful eradication group, those without eradicating or with eradication failure were enrolled into eradication failure group, those with HP negative were enrolled into HP-negative group.And then the occurrence and risk factors of MGC after ESD among the three groups were statistically analyzed.Results:MGC were detected in 58 cases(7.7%)in elderly patients with early gastric cancer after ESD.The median follow-up time was 39 months.The multivariate regression analysis results of MGC showed that no HP-eradication or HP eradication of failure( HR=2.231, 95% CI: 1.054-4.722, P=0.036)and multiple lesions( HR=1.857, 95% CI: 1.076-3.204, P=0.026)were independent risk factors.Non-smoking was a protective factor for the occurrence of MGC( HR=0.409, 95% CI: 0.234-0.716, P=0.002). After adjusting for confounding factors, Cox proportional risk regression analysis showed that the incidence of MGC was significantly higher in group of no HP-eradicating or HP-eradicating of failure than in group of successful HP-eradicating group( χ2=37.877, P<0.001). Conclusions:HP eradication can effectively prevent MGC in elderly patients with early gastric cancer after ESD.Multiple lesions and smoking are independent risk factors for MGC.

Objective To prepare a sustained-release membrane with longer adhesion time and dissolution time, and compare it with the commercially available oral ulcer membrane. Method Adhesion strength, adhesion time, swelling coefficient, dissolution time, etc. were used as the inspection indicators, and a combination of single factor inspection and analytic hierarchy process were used to screen the membrane -forming materials. The dispersion method of clotrimazole, ornidazole and borneol were investigated to prevent the drug from seed out. The method of combining orthogonal experiment and analytic hierarchy process were used to optimize the dosage of CMC-Na, PVA-1788 and glycerin; and the commercial products were compared. Results Through single-factor investigation and orthogonal experiment, the optimal ratio of excipients was selected as CMC-Na∶PVA-1788∶glycerol (3∶1∶0.08). The water-insoluble component clotrimazole, ornidazole and borneol were treated by precipitation in liquid with good effect. The best method was used to prepare the membrane. The adhesion strength was 102 g. The adhesion time was 55 min. The swelling coefficient was 1 939.52. The average dissolution time was 110 min. The appearance was white and the surface was free of bubbles, soft and elastic. The membrane forming time at 60 ℃ was 300 min and the demolding effect was better which could be completely peeled off with moderate thickness. Conclusion The oral ulcer membrane developed in this method has good appearance, comfortable use, strong adhesion, long adhesion time and dissolution time, and could stay on the ulcer surface for a long time to form physical isolation, and slowly release the drug during the dissolution process, which could play the role of long-term pain relief, antibacterial, anti-inflammatory and promote healing effects on oral ulcers.

The coronavirus disease 2019 (COVID-19) pandemic has stimulated tremendous efforts to develop therapeutic agents that target severe acute respiratory syndrome coronavirus 2 to control viral infection. So far, a few small-molecule antiviral drugs, including nirmatrelvir-ritonavir (Paxlovid), remdesivir, and molnupiravir have been marketed for the treatment of COVID-19. Nirmatrelvir-ritonavir has been recommended by the World Health Organization as an early treatment for outpatients with mild-to-moderate COVID-19. However, the existing treatment options have limitations, and effective treatment strategies that are cost-effective and convenient for tackling COVID-19 are still needed. To date, four domestically developed oral anti-COVID-19 drugs have been granted conditional market approval in China. These drugs include azvudine, simnotrelvir-ritonavir (Xiannuoxin), leritrelvir, and mindeudesivir (VV116). Preclinical and clinical studies have explored the efficacy and tolerability of mindeudesivir and supported its early use in mild-to-moderate COVID-19 cases at high risk for progression. In this review, we discuss the most recent findings regarding the pharmacological mechanism and therapeutic effects focusing on mindeudesivir and other small-molecule antiviral agents for COVID-19. These findings will expand our understanding and highlight the potential widespread application of China's homegrown anti-COVID-19 drugs.

Objective:
To investigate the associations of deficits in prepotent response inhibition with attention deficit and impulsive behavior in children with attention deficit hyperactivity disorder (ADHD), so as to provide insights into response inhibition training in ADHD to relieve clinical symptoms.
Methods:
From March to December 2022, 57 children with ADHD were selected from the clinical psychology department of a tertiary hospital in Hangzhou City as the ADHD group, and 55 normal children matched by age and gender were selected from a primary school as the control group. Prepotent response inhibition, attention deficit and impulsive behavior were assessed by inhibition conflict task, visual continuous performance test (CPT) and matching familiar figures test (MFFT), respectively. The associations of deficits in prepotent response inhibition with attention deficit and impulsive behavior were analyzed using multiple linear regression model, and the predictive value of deficits in prepotent response inhibition on ADHD was evaluated using receiver operating characteristic (ROC) curve.
Results:
The children included in the ADHD group had a mean age of (8.77±1.60) years and 44 males (77.19%), and the children included in the control group had a mean age of (9.20±1.77) years and 42 males (76.36%). The error rate of inhibition conflict task, missing report rate of visual CPT and the number of MFFT errors were higher in the ADHD group than in the control group [22.50% (12.50%) vs. 8.75% (7.00%), 24.00% (30.00%) vs. 7.50% (7.00%), 8.67±3.32 vs. 4.47±3.16; all P<0.05]. Multiple linear regression model showed that the error rate of inhibition conflict task was positively associated with the missing report rate of visual CPT (R2=0.135, β=0.091, P<0.001) and the number of MFFT errors (R2=0.092, β=0.009, P<0.001). The area under the ROC curve was 0.891, the sensitivity was 93.00%, the specificity was 80.00%, and the cut-off was 13.13%.
Conclusions
The deficits in prepotent response inhibition are positively associated with attention deficit and impulsive behavior.
