Objective To investigate the clinical efficacy and mechanism of Weiwei Decoction in treating patients with precancerous lesions of gastric cancer(PLGC)differentiated as deficiency-stasis-turbidity syndrome.Methods From August 2021 to August 2023,a clinical observation was performed on 60 patients diagnosed as chronic atrophic gastritis accompanied by mild to moderate dysplasia and differentiated as deficiency-stasis-turbidity syndrome through traditional Chinese medicine(TCM)syndrome differentiation,electronic gastroscopy,and histopathological examination at the Department of Gastroenterology,Guangdong Second Traditional Chinese Medicine Hospital.The patients were randomly divided into a treatment group and a control group using a random number table,with 30 patients in each group.The control group was treated with oral use of Weifuchun Tablets,while the treatment group was given modified Weiwei Decoction according to syndrome differentiation.The treatment course lasted 24 weeks.Before and after treatment,the changes in TCM syndrome scores,gastroscopy and histopathological grading,and expression levels of markers of cancer-associated fibroblasts(CAFs)in gastric mucosal tissues of the two groups were observed.After treatment,the efficacy of TCM syndromes and medication safety were evaluated in both groups.Results(1)After 24 weeks of treatment,the total effective rate in the treatment group was 93.33%(28/30),and that in the control group was 63.33%(19/30).The TCM syndrome efficacy in the treatment group was significantly superior to that in the control group(P＜0.05).(2)After treatment,the TCM syndrome scores in both groups were significantly decreased compared to those before treatment(P＜0.01),and the decrease in the treatment group was significantly superior to that in the control group(P＜0.05).(3)After treatment,the histopathological grading of gastric mucosal atrophy,intestinal metaplasia,and dysplasia in the treatment group was significantly improved compared to that before treatment(P＜0.05),while no significant improvement was presented in the control group(P＞0.05).The improvement in histopathological grading of gastric mucosal atrophy,intestinal metaplasia,and dysplasia in the treatment group was significantly superior to that in the control group(P＜0.05 or P＜0.01).(4)After treatment,the expression levels of CAFs markers of fibroblast activation protein(FAP)and α-smooth muscle actin(α-SMA)in the treatment group were significantly decreased(P＜0.05),while the expression levels of FAP and α-SMA in the control group were significantly increased(P＜0.05)compared to those before treatment.The decrease in FAP and α-SMA expression levels of the treatment group was significantly greater than that of the control group(P＜0.01).(5)During the treatment period,no adverse drug events occurred in either group,indicating high safety.Conclusion Weiwei Decoction has significant therapeutic effect on PLGC patients with deficiency-stasis-turbidity syndrome.Its mechanism may be related to the down-regulation of FAP and α-SMA levels and inhibition of the expression of CAFs.

Objective To investigate the clinical diagnostic value of serum sTREM2 level in patients with cerebral small vessel disease(CSVD)and its correlation with depression and its severity.Methods A total of 208 CSVD inpatients admitted in Department of Neurology of the First Affiliated Hospital of Shihezi University from December 2023 to November 2024 were en-rolled,and according to their score of HAMD,they were divided into a depression group(CSVD+D group,112 cases)and a non-depression group(CSVD—D group,96 cases).According to the 17-item HAMD,the depression group(CSVD+D group)was further divided into mild(8-17,n=80),moderate(18-24,n=27)and severe depression(≥25,n=5)subgroups.Another 208 healthy individuals who taking health checkups in the same period were selected and served as the control group.The general clinical data were compared among the groups and subgroups,and mul-tivariate logistic regression analysis was applied to identify the risk factors for the occurrence of depression and the relationship between sTREM2 and depression severity in the CSVD patients.ROC curve was plotted to evaluate the predicative performance of serum sTREM2 level for the occurrence of depression in the CSVD patients.Results The serum sTREM2 level was remark-ably higher in the CSVD patients than the control group(5.95±3.82 μg/L vs 1.40±1.21 μg/L,P＜0.01).ROC curve analysis indicated that the AUC value of serum sTREM2 level in predicting CSVD was 0.917,with a sensitivity of 87.52％and a specificity of 85.64％,and an optimal cut-ff value of 2.272 μg/L.The CSVD+D group also had significantly higher serum sTREM2 level than the CSVD—D group(6.40±3.93 μg/L vs 5.01±2.87 μg/L,P＜0.01).Multivariate logistic regression analysis showed that serum sTREM2 level was an independent influencing factor for occurrence of depression in the CSVD patients(OR=1.115,95％CI:1.019-1.220,P=0.018).Statistical difference was also observed in the patients without and with mild,moderate and severe depression(P＜0.05).Multivariate ordinal logistic regression analysis revealed that serum sTREM2 level was an independent influencing factor for mild,moderate and severe depression(OR=1.113,95％CI:1.013-1.223,P=0.026;OR=1.135,95％CI:1.004-1.284,P=0.043).The AUC value of serum sTREM2 level in predicting depressive symptoms in CSVD patients was 0.603.Conclusion Serum sTREM2 is closely associated with CSVD patients.Its level may provide certain reference value for clinical diagnosis of CSVD,and has potentially predictive value for the occurrence of depression in the CSVD patients.
