Non-small cell lung cancer(NSCLC) is the most common type of lung cancer worldwide, accounting for approximately 80%-85% of all lung cancer cases. Despite the clinical benefits of traditional treatments such as surgery, chemotherapy, and radiotherapy, challenges such as the high rate of postoperative recurrence and resistance of some patients to chemotherapy and targeted therapies limit their effectiveness, necessitating the exploration of more effective treatment options. In recent years, immunotherapy, especially immune checkpoint inhibitors(ICIs), has revolutionized NSCLC treatment and significantly improved the survival prognosis of some patients. However, the efficacy of immunotherapy is limited by tumor immune escape, drug resistance, and immune-related adverse events(irAEs), which have not been effectively addressed. Traditional Chinese medicine(TCM), as a traditional therapeutic approach, has shown unique advantages in NSCLC treatment, with studies indicating its ability to enhance immune responses, regulate immune checkpoints, and improve the tumor microenvironment(TME), thus boosting the efficacy of immunotherapy. Additionally, the multi-target and multi-pathway effects of TCM help mitigate the side effects of immunotherapy, further improving efficacy and safety. This review summarizes the latest research progress of TCM in NSCLC immunotherapy, focusing on the research results of TCM in enhancing the effect of immunotherapy by regulating immune cells, optimizing the immune microenvironment, and being applied with ICIs, etc. The latest research progress of TCM in alleviating irAEs is also elucidated. The aim is to provide theoretical support for the clinical application of TCM in the prevention and treatment of NSCLC and the research and development of new drugs and promote the optimization and development of combined immunotherapy and TCM treatment models.

Since the first successful transcatheter aortic valve replacement (TAVR) was performed globally in 2002, the TAVR technology has become increasingly mature. With more than a decade of development in China, its application experience, device research and development, procedural improvements, evidence-based medicine, and guideline updates have continuously progressed, leading to a significant increase in the number of procedures conducted. Compared to traditional surgical operations, TAVR has different postoperative monitoring points and principles for the prevention and management of complications, necessitating the formulation of corresponding monitoring and treatment protocols that align with the technical characteristics of the procedure. This guideline is based on clinical practice and incorporates both domestic and international literature as well as the experiences of Fuwai Hospital. It distills and organizes routine postoperative monitoring practices, process optimization, and complication management for TAVR, establishing a set of practical guidelines for postoperative monitoring in China. These guidelines have strong practical value for optimizing postoperative management strategies and preventing and managing complications, which is beneficial for early functional recovery of patients, shortening hospital stays, and reducing complication rates. They provide guidance and reference for domestic peers and support the standardized development and quality improvement of postoperative management for TAVR in China.

Objective To investigate the mechanisms by which paeoniflorin improves tissue and cell damage caused by diabetic retinopathy(DR)through the hypoxia-induced factor-1α(HIF-1α)pathway.Methods Thirty rats were ran-domly divided into a control group(10 normal rats),a DR group(10 diabetic model rats)and a paeoniflorin group(10 dia-betic model rats given 80 mg·kg-1 paeoniflorin by gavage).Rat retinal microvascular endothelial cells(rRMECs)were di-vided into a control group(cultured with 5 mmol·L-1 glucose),a high glucose group(cultured with 30 mmol·L-1 glu-cose)and a paeoniflorin group(cultured with 30 mmol·L-1 glucose and 20 mol·L-1 paeoniflorin).The three groups of cells were all cultured for 24 h.Fasting blood glucose was measured by a glucose meter.Hematoxylin and eosin(HE)stai-ning was used to detect the retinal histopathological structure.The levels of HIF-1α and vascular endothelial growth factor(VEGF)proteins and mRNAs in retinal tissues and rRMECs were detected by Western blotting and real time quantitative polymerase chain reaction(RT-qPCR).The proliferative ability of rRMECs was detected by the EdU kit.The serum levels of total cholesterol(TC),triglyceride(TG),low density cholesterol(LDL-C),interleukin-6(IL-6)and tumor necrosis factor-α(TNF-α)in retinal tissues and rRMECs were detected by kits.The activity and invasive ability of rRMECs were measured by CCK-8 and Transwell assay,respectively.The levels of HIF-1α and VEGF proteins in rRMECs were detected by immunofluorescence staining.Results Compared with those in the DR group,the fasting blood glucose,TC,TG and LDL-C levels in the paeoniflorin group were significantly decreased(all P＜0.05).The retinal tissue was loose with an un-clear boundary in the DR group,compared with that in the control group.The retinal tissue in the paeoniflorin group was less loose with a clearer boundary than that in the DR group.The levels of HIF-1α and VEGF proteins and mRNAs,TNF-αand IL-6 in retinal tissues of the DR group were significantly higher than those of the control group(all P＜0.05).The lev-els of HIF-1α and VEGF proteins and mRNAs,TNF-α and IL-6 in retinal tissues of the paeoniflorin group were significantly lower than those in the DR group(all P＜0.05).The activity,proliferation and invasive abilities of rRMECs in the high glu-cose group were higher than those in the control group(all P＜0.05).Compared with those in the high glucose group,rRMECs in the paeoniflorin group showed decreased cell activity,proliferation and invasive abilities(all P＜0.05).The lev-els of HIF-1α and VEGF proteins and mRNAs,TNF-α and IL-6 in the rRMECs of the high glucose group were higher than those of the control group(all P＜0.05).The levels of HIF-1α and VEGF proteins and mRNAs,TNF-α and IL-6 in the rRMECs of the paeoniflorin group were lower than those of the high glucose group(all P＜0.05).Conclusion Paeoni-florin can down-regulate the HIF-1α/VEGF pathway to improve the inflammatory injury of the retinal tissue and inhibit rRMEC activity,proliferation and invasive abilities in DR rats,thereby preventing angiogenesis and reducing the incidence of DR.

The establishment of an intelligent audit system for hospital medical insurance is crucial for standardizing irrational practices and curbing the unwarranted escalation of medical insurance costs. A tertiary hospital has developed comprehensive prescription review rules in terms of indications, nutritional risk assessments, pain score evaluations, drug sensitivity test results, and target patient populations. When using medical insurance funds for settlement, both systematic and manual reviews are conducted, and three-level intervention measures such as " prompt, review, and interception" are implemented based on prescription issues. After the system was put into use, the hospital′s in-process information system supervision mode shifted from the previous focus on prompts to focus on audits. The medical insurance intelligent audit system provided timely prompts and interventions, and the number of unreasonable medical insurance prescriptions and deductions from medical insurance sampling prescriptions significantly decreased ( P<0.001), while the number of medical insurance medication prescription audits increased ( P<0.001). The application of the intelligent medical insurance medication audit system has improved the efficiency of prescription auditing and ensured the rationality of the use of medical insurance funds.

OBJECTIVE To study the pharmacological substance basis of Shaoyao gancao decoction for relieving acute and chronic pain. METHODS The antispasmodic effect of Shaoyao gancao decoction， ethyl acetate extract of Shaoyao gancao decoction and its effluent part of macroporous resin and 90% ethanol elution part of macroporous resin （the concentration of 4 drugs was 13.44 g/mL according to crude drug） was observed by in vitro small intestine tension test in rats. The acetic acid writhing test was conducted in mice to evaluate the analgesic effects of macroporous resin efflux site and macroporous resin 90% ethanol elution site （the dosage of 2.4 g/kg according to crude drug）. The levels of tumor necrosis factor-α （TNF-α）， interleukin-1β （IL- 1β）， prostaglandin E2 （PGE2） and cyclooxygenase-2 （COX-2） in serum of mice were detected. The serum prototype and metabolites of mice after intragastric administration of macroporous resin 90% ethanol elution site were identified by high performance liquid chromatogre-time-of-flight mass spectrometry. RESULTS In vitro experiment showed that 90% ethanol eluting part of macroporous resin represented the best antispasmodic effect， and the inhibitory rate of small intestine tension was significantly higher than macroporous resin efflux site of Shaoyao gancao decoction （P＜0.05） without statistical significance， compared with Shaoyao gancao decoction （P＞0.05）. In the acetic acid writhing experiment， compared with model group， the writhing times of mice in the macroporous resin 90% ethanol elution part group were reduced significantly （P＜0.05）， the writhing latency was prolonged significantly （P＜0.05）， and the levels of COX-2， IL-1β， PGE2 and TNF-α in serum were decreased significantly （P＜0.05）. Ten kinds of protoproducts including paeoniflorin and glycyrrhizic acid were identified from serum of mice， and twenty-two kinds of metabolites including hydroxylated glycyrrhizin and glucosylated liquiritin were identified. CONCLUSIONS The effective part of Shaoyao gancao decoction for relieving acute and chronic pain is 90% ethanol elution part prepared by macroporous resin from the ethyl acetate extract. Ten components， including glycyrrhetinic acid and paeoniflorin， may be the basis of its pharmacological substances.

Background/Aims: Low educational attainment is a well-established risk factor for nonalcoholic fatty liver disease (NAFLD) in developed areas. However, the association between educational attainment and the risk of NAFLD is less clear in China. Methods: A cross-sectional study including over 200,000 Chinese adults across mainland China was conducted. Information on education level and lifestyle factors were obtained through standard questionnaires, while NAFLD and advanced fibrosis were diagnosed using validated formulas. Outcomes included the risk of NAFLD in the general population and high probability of fibrosis among patients with NAFLD. Logistic regression analysis was employed to estimate the risk of NAFLD and fibrosis across education levels. A causal mediation model was used to explore the potential mediators. Results: Comparing with those receiving primary school education, the multi-adjusted odds ratios (95% confidence intervals) for NAFLD were 1.28 (1.16 to 1.41) for men and 0.94 (0.89 to 0.99) for women with college education after accounting for body mass index. When considering waist circumference, the odds ratios (95% CIs) were 0.94 (0.86 to 1.04) for men and 0.88 (0.80 to 0.97) for women, respectively. The proportions mediated by general and central obesity were 51.00% and 68.04% for men, while for women the proportions were 48.58% and 32.58%, respectively. Furthermore, NAFLD patients with lower educational attainment showed an incremental increased risk of advanced fibrosis in both genders. Conclusions In China, a low education level was associated with a higher risk of prevalent NAFLD in women, as well as high probability of fibrosis in both genders.
