OBJECTIVES: To identify potential molecular targets of quercetin in the treatment of clear cell renal carcinoma (ccRCC). METHODS: The therapeutic targets of quercetin were screened from multiple databases by network pharmacology analysis, and the targets significantly correlated with ccRCC were screened from 4907 plasma proteins using a Mendelian randomization method. The drug-disease network model was constructed to screen the potential key targets. The functions of these targets were evaluated via bioinformatics analysis, and the screened targets were verified in cultured ccRCC cells. RESULTS: Network pharmacology analysis combined with Mendelian randomization identified TP53 (OR=3.325, 95% CI: 1.805-6.124, P=0.0001), ARF4 (OR=0.173, 95% CI: 0.065-0.456, P=0.0003), and DPP4 (OR=0.463, 95% CI: 0.302-0.711, P=0.0004) as the core targets in quercetin treatment of ccRCC. Bioinformatics analysis showed that TP53 was highly expressed in ccRCC, and patients with high TP53 expressions had worse survival outcomes. Molecular docking studies showed that the binding energy between quercetin and TP53 was -5.83 kcal/mol. In cultured 786-O cells, CCK-8 assay and wound healing assay showed that treatment with quercetin significantly inhibited cell proliferation and migration. Quercetin treatment also strongly suppressed the expression of TP53 at both the mRNA and protein levels in 786-O cells as shown by RT-qPCR and Western blotting. CONCLUSIONS TP53 may be the key target of quercetin in the treatment of ccRCC, which sheds light on potential molecular mechanism that mediate the therapeutic effect of quercetin.

Objective:To explore the clinical efficacy of endoscopic sleeve gastrectomy (ESG) in the treatment of obesity.Method:A 26 year old female patient was admitted on October 20, 2022 due to a progressive increase in weight for 2 years. Her body mass index (BMI) was 30.04 kg/m 2, body fat percentage was 39.2%, and visceral fat grade was 15. ESG was performed using the OverStitch SX endoscopic suture system. Result:The surgery was successful, with approximately 5 ml of intraoperative bleeding.The patient discharged on the first day after surgery. Two weeks after surgery, small bowel follow-through showed a tubular shape of the stomach. At 6 months after surgery, the BMI was 25.2 kg/m 2, body fat percentage was 32%, visceral fat grade was 10. The total body weight loss rate (%TBWL) at 6 months after surgery was 16%, and the excess weight loss rate (%EWL) was 54.5%. Conclusion:ESG is effective for the treatment of obesity.

Periodontitis is a chronic inflammatory and immune reactive disease induced by the subgingival biofilm.The therapeutic effect for susceptible patients is often unsatisfactory due to excessive inflammatory response and oxidative stress.Sinensetin(Sin)is a nature polymethoxylated flavonoid with anti-inflammatory and antioxidant activities.Our study aimed to explore the beneficial effect of Sin on periodontitis and the specific molecular mechanisms.We found that Sin attenuated oxidative stress and inflammatory levels of periodontal ligament cells(PDLCs)under inflammatory conditions.Administered Sin to rats with ligation-induced periodontitis models exhibited a protective effect against periodontitis in vivo.By molecular docking,we identified Bach1 as a strong binding target of Sin,and this binding was further verified by cellular thermal displacement assay and immunofluorescence assays.Chromatin immunoprecipitation-quantitative polymerase chain reaction results also revealed that Sin obstructed the binding of Bach1 to the HMOX1 promoter,subsequently upregulating the expression of the key antioxidant factor HO-1.Further functional experiments with Bach1 knocked down and overexpressed verified Bach1 as a key target for Sin to exert its antioxidant effects.Additionally,we demonstrated that Sin prompted the reduction of Bach1 by potentiating the ubiquitination degradation of Bach1,thereby inducing HO-1 expression and inhibiting oxidative stress.Overall,Sin could be a promising drug candidate for the treatment of periodontitis by targeting binding to Bach1.

Objective:The aim of this study is to develop a comprehensive index system for assessing the key first aid skills required for aeromedical evacuation of infected patients, with the goal of enhancing our army's medical support capabilities.Methods:This study combined literature review and two rounds of Delphi expert correspondence to construct the key first aid skills index system of aeromedical evacuation for infected patients. 19 experts from relevant disciplines were selected purposively to conduct Delphi expert consultation.Results:Both rounds of Delphi expert correspondence achieved a 100% response rate, indicating high effectiveness. The degree of authority among the experts was determined to be 0.87. In the first round, there was a Kendall coordination coefficient value of 0.184 for assessing the importance of primary indicators, while secondary indicators showed coefficients of 0.289 and 0.380 for importance and feasibility respectively. In the second round, these values increased slightly to 0.263, 0.304 (importance) and 0.398 (feasibility), respectively. The final evaluation index system of key first aid skills applied to the aeromedical evacuation of infected patients was constructed, including 3 primary indicators of life support technology, intensive care technology and isolation protection technology, and 40 secondary indicators.Conclusion:The evaluation index system of key first aid skills applied to the aeromedical evacuation of infected patients constructed through two rounds of Delphi expert correspondence is scientific and reasonable, which can provide reference for the training and assessment of key first aid skills applied to the aeromedical evacuation of infected patients, so as to promote the development of aeromedical evacuation for infectious patients in China.

Objective To explore the high-quality development path of tertiary public hospitals and provide scientific reference for deepening the reform of public hospitals.Methods Based on SPO theory,it constructed an analytical framework for the high-quality development of tertiary public hospitals,collected data of a quarterly monitoring in-dex for the performance assessment and high-quality development of tertiary public hospitals in a certain province in 2023,and analysed 73 tertiary public hospitals participating in the performance assessment as the object of analy-sis,and adopted the fuzzy-set Qualitative Comparative Analysis to explore different condition sets of high-quality de-velopment of tertiary public hospitals and reveal the path of high-quality development of public hospitals.Results High-quality development is the result of multi-factor interaction.Four configurations were identified to promote the high-quality development of tertiary public hospitals:service quality-technology-driven path,service quality-driven path,comprehensive service-driven path,and service quality-benefit-driven path.Quality safety and functional orientation were found to be the core elements in promoting high-quality development of public hospitals.Conclusion Hospitals at all levels should strengthen the guidance of party building,combine with the actual functional positioning,take quality and safety as the core,and optimize the combination conditions of technical level,personnel structure,service process,and cost control.It is essential to clarify the development strategy of hospitals,implement the dynamic concept,and realize the high-quality development of public hospitals.
