Inflammatory bowel disease （IBD）， mainly including ulcerative colitis （UC） and Crohn's disease （CD）， is a common chronic inflammatory disease of the gastrointestinal tract， with its incidence increasing year by year. Due to its long treatment duration， difficulty in treatment， prolonged remission， and high costs， it has attracted global attention. Exploring safe， effective， and sustainable treatment regimens has become an urgent global issue. The pathogenesis of IBD is complex， involving intestinal mucosal injury，disturbances in the internal environment， and inflammatory responses. In recent years， research has found that ferroptosis is also one of the important pathogenic factors of IBD. Ferroptosis， as a new form of non-apoptotic cell death， is characterized by iron dependence， lipid peroxidation， and imbalance in the redox system. Studies have shown that inhibiting ferroptosis in intestinal epithelial cells can protect the intestinal mucosa. Targeted intervention in ferroptosis may be a new direction for the treatment of IBD. IBD is mainly treated with drugs， including corticosteroids， aminosalicylates， biologics， and immunomodulators， but drug resistance and adverse reactions are common. Traditional Chinese medicine （TCM） has unique advantages such as low cost， low drug resistance， and fewer side effects， and has accumulated rich experience in the treatment of IBD. Scholars have confirmed that TCM can inhibit ferroptosis， and recent studies have shown that TCM can not only inhibit iron-dependent lipid peroxidation in intestinal cells but also enhance the antioxidant and anti-inflammatory abilities of intestinal mucosa， thus playing a role in the treatment of IBD. Increasing evidence suggests that TCM may treat IBD by interfering with ferroptosis. This article explores the relevance of TCM intervention in ferroptosis and the treatment of IBD， discusses the possible mechanisms of ferroptosis in IBD， and aims to provide a basis for the diagnosis and treatment of IBD.

Bronchial asthma （asthma for short） is a common clinical respiratory disease mainly characterized by chronic airway inflammation， with complicated pathogenesis and a long treatment cycle. It is lingering and difficult to be cured， and lack specific drugs. Oxidative stress is a new focus in the research on the pathogenesis of asthma and a potential key target for the treatment. Under physiological conditions， the oxidative and antioxidative systems in the body are in a dynamic balance， and the two antagonize each other to maintain normal life activities. In the case of asthma attack， oxidation products such as reactive oxygen species （ROS）， malondialdehyde （MDA）， and nitric oxide （NO） are produced excessively， while the content of antioxidants such as superoxide dismutase （SOD）， catalase （CAT）， and glutathione （GSH） is reduced. As a result， the oxidation exceeds the removal of oxidation products， which aggravates oxidative stress. In addition， the overproduction of ROS activates oxidative stress-related signaling pathways to produce pro-inflammatory factors， exacerbating inflammation， which leads to lung and airway tissue damage. In recent years， traditional Chinese medicine has garnering increasing attention because of the unique advantages in the treatment of asthma， especially in regulating redox balance， alleviating oxidative stress in asthma patients， and reducing inflammation. On the one hand， by inhibiting the mitogen-activated protein kinase （MAPK） and transcription factor （NF）-κB signaling pathways， traditional Chinese medicine can reduce the content of oxidation products and pro-inflammatory factors from the source. On the other hand， by activating the nuclear factor-erythroid 2-related factor 2 （NrF2） signaling pathway， traditional Chinese medicine can elevate the levels of antioxidant enzymes and enhance the antioxidant system to neutralize the excessive accumulation of oxidation products. Therefore， the adjustment of redox balance state by traditional Chinese medicine may be a new means and a new direction for the prevention and treatment of asthma in the future. This paper summarizes the oxidative stress-related pathways in the pathogenesis of asthma and reviews the latest research progress in the regulation of oxidative stress-related pathways by Chinese medicine extracts and prescriptions in the treatment of asthma， with a view to providing a fuller， more solid， and more scientific theoretical basis for the clinical and basic research on the prevention and treatment of asthma by traditional Chinese medicine.

Objective Summarize the key difficult problems faced by national regional medical centers,create a checklist of crucial issues,and propose strategic recommendations to support future development.Methods It employed a combination of literature review,field research,and in-depth interviews to develop an initial draft of the checklist for key issues in national regional medical centers.Additionally,two rounds of Delphi method consultation were conducted with experts from local government,exporting and supporting hospitals.The data gathered from the questionnaires in both rounds were analyzed,and essential questions were identified.Results The questionnaires achieved response rates of 99%and 100%in the two rounds,and the expert authority coefficients were 0.83 and 0.90.The final checklist for key issues in national regional medical centers encompassed a total of 6 problems.These included 3 challenges related to establishing sound management systems and mechanisms,1 challenge concerning human resource management improvement,1 challenge focusing on elevating medical service levels,and 1 challenge pertaining to other aspects of progress.Conclusion Currently,the development of national regional medical centers encounters crucial challenges,including the enhancement of management mechanisms,overall human resource management,and medical capabilities.The government should reinforce leadership assurance,coordination,and supervisory responsibilities.Exporting hospitals should enhance management systems and operational mechanisms.Supporting hospitals should focus on effective party building guidance and cooperation while consistently promoting the uniform development of national regional medical centers.

Objective:To explore the clinical characteristics and risk factors of abnormal urinary albumin/creatinine ratio(UACR) in obese population.Methods:Baseline data from 2011 to 2012 in Henan Sub-center of"Risk Evaluation of cAncers in Chinese diabeTic Individuals: A lONgitudinal(REACTION) study"were utilized and those of body mass index≥28 kg/m 2 were screened. The patients were divided into UACR normal group and UACR abnormal group(101 pairs) upon being matched on a 1∶1 basis by age and gender. Multivariate logistic regression analysis, receiver operating characteristic(ROC) curve, and restricted cubic spline(RCS)analysis were performed to explore the risk factors for abnormal UACR. Results:Compared with the normal UACR group, the UACR abnormal group had a higher number of alcohol consumers, a higher prevalence of hypertension, elevated systolic blood pressure, and triglyceride(all P<0.05). Multivariate logistic regression analysis showed that alcohol consumption( P=0.008), systolic blood pressure( P<0.001), triglyceride( P=0.049), and homeostasis model assessment for insulin resistance(HOMA-IR, P=0.033) were independent risk factors for abnormal UACR in obese people. The ROC curve analysis indicated that systolic blood pressure had the strongest diagnostic performance as a single factor(ROC curve area=0.801), and there was no significant difference in diagnostic performance compared to multiple factors combination. RCS analysis results showed that the probability of abnormal UACR increased monotonically with the increase of systolic blood pressure when the systolic blood pressure was between 130 and 158 mmHg(1 mmHg=0.133 kPa). When systolic blood pressure was not in the interval, the probability of abnormal UACR did not change significantly. The results of regression analysis of triglyceride subgroup showed that when triglyceride level was greater than or equal to 5.6 mmol/L, the risk of abnormal UACR level was significantly increased( P=0.029). Conclusion:Systolic blood pressure, triglyceride, HOMA-IR, and alcohol drinking history are independent risk factors for abnormal UACR in obese people. When systolic blood pressure is≥130 mmHg or triglyceride is≥5.6 mmol/L, the risk of abnormal UACR is significantly increased.
