Objective:This study aims to investigate the relationship between high-risk human papillomavirus (HR-HPV) infection and the composition of vaginal microecology. It will analyze the efficacy of integrated traditional Chinese and Western medicine intervention in treating HR-HPV infection, as well as the effects of this combined approach on vaginal microecology. Additionally, the study seeks to identify new methods to inhibit the malignant progression of cervical intraepithelial lesions.Methods:A prospective study was conducted involving 100 patients with HR-HPV infection who visited the Department of Gynecology, The Second Affiliated Hospital of Shaanxi University of Chinese Medicine from April to June 2023. The participants were randomly divided into a control group and an observation group, with 50 patients in each group using a random number table method. The control group received interferon treatment, while the observation group was treated with a combination of interferon and Yanfukang Lotion. High-throughput DNA sequencing of vaginal secretions was conducted to compare the differences in pre- and post-treatment vaginal microecological composition and the rate of HR-HPV clearance between the two groups. Results:In the observation group, both the diversity index and the abundance of vaginal microecology showed significant improvements compared with the control group, particularly in the abundance of dominant Lactobacillus species. These differences were statistically significant ( R = 0.124, 0.304, 0.030, all P < 0.05). The rates of HR-HPV clearance and overall effective rate (clearance + effective) in the observation group were 44% (22/50) and 68% (34/50), respectively, which were significantly higher than those in the control group [20% (10/50), 32% (16/50), χ2 = 12.98, both P < 0.05). There was no statistically significant difference in the incidence of adverse reactions between the two groups (χ2 = 1.76, P > 0.05). Conclusion:The combination of interferon and Yanfukang Lotion effectively treats HR-HPV infection by regulating the composition of vaginal microecology. This approach shows considerable efficacy and good safety, indicating its potential for further clinical application.

With the rapid development of imaging and percutaneous coronary intervention, the application of contrast media has become more and more widespread, and contrast-associated AKI has become one of the most common causes of acute kidney injury. Contrast-associated AKI seriously threatens patients' health and brings greater economic burden to patients, so it is particularly important to prevent the contrast-associated AKI. Nicorandil is a common vasodilator drug in clinical practice, widely used in the treatment of angina pectoris, with the effects of anti-oxidative stress, anti-apoptosis, anti-inflammatory and vasodilation, and is considered to be effective in preventing contrast - associated AKI. However, there is still a lack of further research on the efficacy of nicorandil in preventing contrast-associated AKI.

Objective: To understand the homology and resistance characteristics of Streptococcus pneumoniae (S. pneumoniae) in healthy preschool children, so as to provide basis for disease transmission prevention and rational use of antibiotics. Methods: Stratified cluster random sampling method was used to sample 1 829 healthy children from six kindergartens in Shunde District, Foshan City. Nasal swabs were taken and tested for S. pneumoniae. Multi locus sequence typing was used for homology analysis. The Chi squared test and random forest analysis were used to explore the resistance characteristics. Results: The nasal carriage rate of S. pneumoniae and multidrug resistant S. pneumoniae (MDRSP) in children were 22.5%(412/1 829) and 21.3%(390/1 829), respectively. Homology analysis in sequence types showed that the total homology rates of 6 kindergartens were 93.5%(87/93), 91.1% (72/79), 89.2%(58/65), 88.9%(64/72), 86.2%(50/58), 77.8%(35/45), respectively. It was found that the highest homology rate was 82.8% (48/58) within class and 93.1% (81/87) between classes. S. pneumoniae was mainly resistant to azithromycin (97.1%, 400/412), erythromycin (92.0%, 379/412) and tetracycline (91.5%, 377/412). The dominant multidrug resistance pattern of MDRSP isolates was not sensitive to azithromycin, erythromycin, cotrimoxazole, tetracycline and clindamycin. Random forest analysis indicated that the important phenotypic markers associated with MDRSP were resistance to azithromycin, cotrimoxazole, tetracycline, clindamycin and erythromycin(MDG=8.94, 6.92, 5.80, 4.84, 2.58). Conclusion The risk of cross transmission of S. pneumoniae among preschool children is high, and direct contact is the main way of transmission. Consequently, kindergartens and health departments should take effective measures to effectively prevent and block the spread of Streptococcus pneumoniae.

Objective:To develop and internally validate a fall related injury risk nomogram in of patients in Patients in hospital.Methods:Patients who fall during the hospital stay from a grade-three general hospital of Zhejiang province were recruited. Data were collected from January 2014 to December 2019. Data was collected after patients fall in hospital, including age, sex, and 18 other predictive factors. The LASSO regression model and multivariable logistic regression analysis were applied to build a predicting model. Discrimination and calibration of the predicting model were assessed using the C-index and calibration plot. Internal validation was assessed using the bootstrapping validation.Results:Of the 243 patients included in the study, 70 patients had fall related injury. The fall related injury probability was 28.81%. Predictors contained in the prediction nomogram included age≥60, dysfunction, combined utilization of special drugs, no-escort, hypocalcemia. The model displayed good discrimination with a C-index of 0.823 (95% confidence interval 0.756-0.875) and good calibration. High C-index value of 0.803 could still be reached in the interval validation.Conclusion:This fall related injury risk nomogram in of patients in Patients in hospital incorporating the age≥60, dysfunction, combined utilization of special drugs, no-escort, hypocalcemia could be conveniently used to predict fall related injury risk of patients in hospital.

The motor function of the trunk in 10 hemiplegic patlents was evaluated with Biodex Sys- tem Ⅱisokinetic testing aparatus. The result shows that the strength of flexors and extensors of the trunk,especially the flexors,becomes weaker(The ratio of flexors to extensors is less than 1).The patients weretreated with a series of the trunk retraining methods. The motor function of the trunk was improved aftertreatment(P<0.01 ).The total motor function(Fugl-Meyer Assessing Scale)also makes significant progress(P<0.01).The study proposes that the retraining and regaining of the trunk motor function in hemiplegiais quite important not only to the trunk but also to total motor function.
