Objective:This paper aimed to investigate the effects of isocorydinone on cell proliferation in SiHa human cervical carcinoma cell lines. Methods:Different concentrations of isocorydione (100, 200, 400, 800, and 1200 μmol/L) were used to treat SiHa human cervical carcinoma cells in vitro for 24, 48, and 72 h. Methyl thiazolyl tetrazolium (MTT) assays were conducted to determine the inhibitory action of isocorydione. Flow cytometry was performed to detect the cell cycle in SiHa human cervical carcinoma cells af-ter treatment with 400 μmol/L isocorydione. Hoechst 33342 staining was used to observe the micro-morphological changes of SiHa cell nucleus after the treatment. The expression of Bcl-2, Bax, and caspase-3 proteins in cervical carcinoma SiHa cell lines was determined using western blot analysis. Results: MTT assays showed that isocorydione inhibits the proliferation of SiHa cells in a dose- and time-dependent manner (P<0.05). The flow cytometry results showed that SiHa cervical carcinoma cells treated with different concen-trations of isocorydione exhibited increased cell cycle. Compared with the control group, Hoechst 33342 staining showed that SiHa cells became narrow, with nuclear pyknosis and fragmentation, and formed an apoptotic body after treatment with 400 μmol/L isocoryd-ione for 48 h. Furthermore, western blot analysis proved that isocorydione significantly inhibited the proliferation of SiHa cell lines, and the expression of Bax protein was increased. By contrast, the expression of Bcl-2 protein decreased gradually. Consequently, the ra-tio of Bax/Bcl-2 increased, as well as the expression of caspase-3 protein. Conclusion:Isocorydione exhibited an overt inhibitory ac-tion on SiHa cells. Isocorydione promoted the occurrence of cell apoptosis, which may be associated with related proteins of mitochon-drial apoptotic pathway.

Objective: To investigate the clinical manifestations, endoscopy, pathological features and highrisk factors of ischemic colitis(IC). Methods: The clinical data of 48 inpatients with IC in the Traditional Chinese Medicine Hospital of Yuhuan from January 2016 to December 2017 were analyzed retrospectively.The risk factors of IC were analyzed by logistic regression. Results: IC patients had chronic diseases such as hypertension, hyperlipidemia and diabetes.Clinical symptoms included abdominal pain and bloody stool.Colonoscopy showed that the lesions of colonic mucosa were distributed regionally, manifested as edema, hemorrhage, erosion and pleomorphic ulcer.In severe cases, stenosis of the lumen could be seen.Pathological findings included necrosis, mucosal edema, hemorrhage, ulcer formation, submucosal hemorrhage and inflammatory cell infiltration.Laboratory examination: leukocyte, serum apolipoprotein B, serum fibrinogen, neutrophil, D-dimer, serum TG and TC were higher than normal levels.Logistic regression results showed that hypertension(OR=4.03, P=0.014), diabetes(OR=2.61, P=0.020), high triglyceride (OR=3.21, P=0.022), atrial fibrillation and other factors(OR=2.50, P=0.017) were closely related to the incidence of IC. Conclusion The symptoms of IC are not typical.Early diagnosis should be made by colonoscopy.Hypertension, diabetes, hyperlipidemia and atrial fibrillation are risk factors of IC.

[Abstract ] Objective To compare the accuracy between regular computed tomography colonography (CTC)and dual-energy CTC in lesion detection.Methods Twenty-eight patients with clinical suspicious space occupying lesions of the colon were selected.All patients were underwent dual-energy mode contrast-enhanced CT scan and the data were reconstructed with colonography and dual-energy iodine maps methods.The diameter,enhanced computed tomography (CT)value and iodine value were measured.The results of colonoscopy and pathology were taken as gold standard.The sensitivity, specificity,accuracy,positive predictive value and negative predictive value of regular CTC and dual-energy CTC were compared.Variance analysis was performed for measurement data comparison among groups and chi-square test was used for count data analysis.Results Among 28 patients,colorectal lesions were detected in 24 cases by regular CTC,of which four cases were false-positive and one case was false-negative confirmed by colonoscopy and pathology.Colorectal lesions were detected in 20 cases by dual-energy CTC,of which no false-positive and one case was false negative confirmed by colonoscopy and pathology.The contrast enhanced CT value of polyps,adenoma,adenocarcinoma and stool was (38.54± 6.82),(49.16±7.31 ),(52.61 ±5 .93 )and (34.00±1 .41 )Hu,respectively.The enhanced value of adenoma and adenocarcinoma was significantly higher than that of polyps and stool,the differences were statistically significant among groups (F = 10.760,P = 0.001 ).There was no significant difference between polyps and stool (t=1 .44,P =0.188).The sensitivity of regular CTC and dual-energy CTC in lesion detection was 95 .6% (95 %cofidence interval(CI ):77.9%-99.2%)and 95 .6% (95 %CI :77.9%-99.2%),respectively.The specificity was 42.8% (95 %CI :15 .4%-93.5 %)and 100.0% (95 %CI :47.9%-100.0%).Conclusion Compared with traditional CTC,dual-energy CTC would distinguish lesions from stool,help differentiate between benign and malignant tumors and further increase the accuracy of CTC diagnosis.

Objective To study the status of professional ability of community nurses and its influencing factors. Methods From November 2013 to March 2014,the questionnaire of community nurses'professional ability,general self-efficacy scale and the questionnaire of job satisfaction were used to investigate 240 community nurses in 12 community medical institutions in Beijing. Results The average score of community nurses' professional ability was(3. 92 ± 0. 51)with the highest score in the communication and coordination ability of(4. 08 ± 0. 54)and the lowest score in the evaluation and analysis ability of(3. 81 ± 0. 59). The ability of community nurses was positively related to self-efficacy and working satisfaction( r =0. 520,0. 336;P < 0. 01). As the result of multiple linear regression,general self-efficacy,job satisfaction,age and the final degree were the influencing factors of the professional ability of community nurses(t = 4. 64,4. 47, 5. 72,5. 01,2. 69,7. 15,2. 94;P < 0. 05 ). Multiple factors analysis showed that self-efficacy,working satisfaction,age,education were the influencing factors of the ability of community nurses(P < 0. 05),within which the self-efficacy was the strongest influencing factor(β = 0. 43). Conclusions It is necessary for the managers and educators to attach more importance to community nurses' self-efficacy and job satisfaction,so as to improve the professional ability of the whole community nurse team.

Objective:To investigate the diagnostic value of non-high-density lipoprotein cholesterol (non-HDL-C),ratio of triglyceride to high-density lipoprotein cholesterol (TG/HDL-C), and triglyceride glucose index (TyG) on metabolic syndrome (MS) in adult women.Methods:This was a cross-sectional study. A total of 24 410 adult women who received health examination in health management center of the Affiliated Hospital of Southwest Medical University were selected from January 2019 to December 2021 as subjects. The subjects′ basic information, physical examination results, and laboratory examination data were collected retrospectively. The relationship between non-HDL-C, TG/HDL-C, TyG, and MS in adult women were examined using multivariate logistic regression analysis. The receiver operating characteristic (ROC) curves were constructed and the area under the curve (AUC) were calculated to evaluate the diagnostic value of each indicator for MS in adult women.Results:Among 24 410 adult females, 800 (3.3%) were found to have MS. After adjusting for age, body mass index, waist circumference, hip circumference, systolic blood pressure, diastolic blood pressure, blood uric acid, history of hypertension, history of diabetes, fatty liver, non HDL-C ( OR=1.608), TG/HDL-C ( OR=1.311), TyG ( OR=13.288) were all risk factors for MS in adult women. non-HDL-C, TG/HDL-C, and TyG, as well as their combined AUC of ROC, were 0.795 (95% CI: 0.742-0.776), 0.909 (95% CI: 0.902-0.917), 0.942 (95% CI: 0.937-0.948), and 0.944 (95% CI: 0.937-0.950), respectively. TyG had the highest diagnostic value for MS in adult women among the three indicators, the optimal cutoff value for TyG was 8.237, with a sensitivity of 93.5% and a specificity of 85.5%. Conclusion:non-HDL-C, TG/HDL-C, TyG, as well as their combination, all demonstrate good diagnostic value for MS in adult women.

Objective: To evaluate the comprehensive intervention effect of lunch for primary and secondary school students in Minhang District, so as to provide a theoretical and practical basis for lunch intervention in school. Methods: From October to December 2023, a convenience sampling method was used to select 1 937 students from one primary and secondary school in Minhang District.A comprehensive intervention measure focusing on "reducing oil and salt" for lunch recipe optimization and nutrition education was carried out, and a questionnaire survey was conducted to evaluate the intervention effect three months later. Chi square test and Wilcoxon rank test were used to compare the data before and after the intervention. Results: After intervention, the use of cooking oil and salt, the supply of protein and fat in primary and secondary school lunches were reduced, and had no obvious impact on energy and other major nutrients. After intervention, compared to before intervention, the proportion of primary school students who felt that lunch was greasy decreased (8.9%, 6.2%, χ 2=4.35), and the proportion of primary and secondary school students who felt that lunch were delicious decreased significantly (33.2%, 23.2%; 63.9%, 53.5%, χ 2=26.39, 17.52) ( P < 0.05 ). Secondary school students also felt reduced variety of food ingredients (46.9%, 38.3%, χ 2=16.05, P <0.05). In addition, after intervention, the total surplus rate of primary school students meals decreased (7.4%, 4.4%, χ 2=5.73), mainly reflected in the decrease of the surplus rate of staple foods (7.1%, 2.4%, χ 2=17.39), while the surplus rate of vegetable dishes increased ( 16.0 %, 21.2%, χ 2=6.01) ( P <0.05). Although there was no significant change in the total surplus rate of meals for secondary school students, the surplus rate of staple foods decreased (12.9%, 5.4%, χ 2=33.52), while the surplus rates of meat and vegetable dishes increased (11.2%, 26.9%; 17.5%, 33.2%, χ 2=74.26, 61.88) ( P <0.05). After intervention, there was no statistically significant difference in the overweight and obesity rates of primary school students ( χ 2=0.11,0.43) and secondary school students ( χ 2=0.01,0.00) compared to before intervention( P >0.05). After intervention, the lung capacity of primary school students [1 564 (1 269,1 890) mL] and sitting forward flexion [11.3 (7.6, 15.2) cm] increased compared to before intervention [1 522 (1 259, 1 819 ) mL, 10.5 (6.3, 13.5) cm] ( Z =2.20, 4.68, P <0.01), but there was no statistically significant difference in lung capacity and sitting forward flexion of secondary school students before and after intervention ( Z =-0.46, -0.08, P >0.05). Conclusion The comprehensive intervention of school lunch has promoted a significant decrease in the use of oil and salt in lunch and improved the quality of recipes, and has a positive impact on the situation of leftover lunch and the health of students to a certain extent.
