Objective:To determine the content of baicalin in Zhisou Kechuanning syrup.Methods:.HPLC was used and di erent derivatization reaction conditions were investigated with the optimal conditions found to be the following:the chromatography column was Waters symmetry C 18(5?m;4.6?150mm),the mobile phase(solvent) was a mixture of methanol-0.1% Phosphoric acid(45:55)with a ow rate of 0.8 ml/min,and the detection wavelength was 280nm.Results:The linear range of Bergenin was 0.41-8.13?g with correlation factor r=0.9997,the average recovery was 98.36% and RSD=1.08%.Conclusion:This method is simple,reproducible,and can be used for quantitative determination of baicalin in Zhisou Kechuanning Syrup.

Objective To study the efficacy of gestrinone and Sanjie zhentong capsule for the adjunctive treatment of endometriesis cyst of ovary after laparoscopic operation.Methods 116 patients with ovarian endometriosis cyst after laparoscopic operation were randomly divided into three groups:A group(gestfinone and Sanjie Zhentong capsule,n=42),after operation were given gestrinone(2.5mg each time,two times per-week for 3～months)and Sanjie zhentong capsule(4 pills each time,three times everyday for 3 months);B group(gestrinone,n=38),after operation were only given gestrinone(2.5mg each time,two times per-week for 3-6 months);C group(Sanjie zhentong capsules,n=36),after operation were only given Sanjie zhentong capsules(4 pills each time,three times everyday for 3 months).All patients were followed up for 6～12 months.Results The follow-up visit rate was 96.5%(112/116).A group,B group and C group,their excellence rate was respectively 97.5%,67.6%and 65.7%,their recurrence rate was respectively 2.5%,24.3%and 22.9%.There was significant difference between A group and B group.C group(P＜0.05).Incidence rate of three groups'side effects was respectively 35.0%,29.7%and 14.3%,there was no significant difference among three groups(P＞0.05).Conclusion The efficacy of gestfinone and Sanjie zhentong capsule for the adjunctive treatment of endometriosis cyst of ovary after laparoscopic operation was better than that of the only medicine treatment.

Objective: To investigate expression of TRAP in human tumors and correlativity between TRAP and hTERT and to explore the role of TRAP in tumorigenesis. Methods: TRAP was expressed in E.coli . and polyclonal antibody was prepared by immunization of New Zealand rabbits. Expressions of TRAP gene and hTERT in human tumors were analyzed by immunohistochemistry. The eukaryotic expression vectors of TRAP were constructed and transferred stably into HeLa cells to be analysed with Northern blot, TRAP PCR ELISA, growth curve, nude mouse transplantation. Results: Polyclonal antibody was obtained from New Zealand rabbits immunized with TRAP fuse protein, which was inducibly expressed in E.coli ., and its specificity was verified in Western blot. TRAP staining was detected in 213 (86.2%)of 247 malignant tumors. On the contrary, TRAP in all tissues adjacent to tumors was negative.There is a obvious difference between borderline,pre cancerous and benign lesion in the expression of TRAP.Furthermore, hTERT staining was conducted and its result was consistent with that of TRAP. Up regulation and down regulation of hTERT expression and telomerase activity were observed respectively in HeLa cells transfected stably with sense and antisence TRAP recombination. Increased proliferation presented in the former and growth inhibition in the latter. Besides, in nude mice, tumorigenecity of sense TRAP transfected HeLa cells was enhanced while tumor growth of antisense TRAP transfected HeLa cells was retarded. Conclusion: The expression of TRAP, which could be detected in most of human cancers and part of pre cancerous lesions, was correlated with expression of hTERT. The status of TRAP expression could regulate telomerase activity and present effects on growth and tumorigeneity of cancer cells. This suggests that TRAP is involved in human tumorigenesis through regulation of telermarase activity.

Objective:To explore independent predictors of postoperative delirium in elderly patients by PRe-Operative Prediction of postoperative DElirium by appropriate SCreening (PROPDESC) and Mayo Delirium Prediction (MDP) , and analyze the predictive power of the two models.Methods:This study was a prospective Cohort study. Using the convenient sampling method, a total of 636 elderly surgical patients admitted to the Orthopedics, Gastroenterology, Cardiothoracic and Oncology Departments of Shantou Central Hospital from May to August 2022 were selected as the research objects. PROPDESC and MDP were used to predict postoperative delirium in elderly patients. The area under the receiver operating characteristic ( AUC) and diagnostic characteristics of the two predictive models were compared, and the single factor analysis and Logistic regression analysis were performed on 19 predictive factors of the two models to determine the independent influencing factors of postoperative delirium. Results:The AUC for external verification of the PROPDESC and MDP were 0.87 (95% CI: 0.84-0.90) and 0.89 (95% CI: 0.86-0.92) , respectively. The sensitivity of 71.79% and 80.34%, and specificity of 85.16% and 81.12%, respectively. Logistic regression analysis showed that emergency admission, age, sentence repetition and sequence subtraction in Montreal Cognitive Assessment (MoCA) were independent influencing factors for postoperative delirium ( P<0.05) . Conclusions:The predictive ability of PROPDESC and MDP models to predict postoperative delirium in elderly patients is satisfactory. On this basis, delirium risk assessment tools suitable for different surgical elderly populations in China can be constructed.
