The global distribution of medical resources is uneven and organ shortages are becoming increasingly serious. ASEAN countries have been working hard to explore and promote local organ transplantation in order to alleviate the serious imbalance between organ donation and organ transplantation needs. However, the development of cadaveric organ donation varies among ASEAN countries, and the cadaveric organ donation rate in most countries is generally low. Since 1991, China and ASEAN have evolved from dialogue to strategic cooperation, then to a community with a shared future, and further to a comprehensive strategic partnership, all demonstrating broad prospects for cooperation. This article analyzes the current situation and challenges of organ donation and transplantation in ASEAN countries, combining field visits and its own experience, and proposes strategies for strengthening international cooperation, optimizing policy environment, enhancing technical capabilities, and increasing public awareness in the field of organ donation and transplantation under the China-ASEAN development strategy framework. The aim is to build a more equitable, efficient, and sustainable organ donation and transplantation system, contributing to the realization of global public health security and a community of common health for mankind.

Objective To investigate the effects and related mechanisms of mitochondrial-derived peptide MOTS-c on glycochenodeoxycholic acid (GCDCA)-induced injury in human hepatocytes (THLE-3 cells). Methods THLE-3 cells were cultured in vitro and treated with different concentrations of GCDCA and MOTS-c. The optimal concentrations of GCDCA and MOTS-c were determined by cell counting kit (CCK)-8 method. Subsequently, THLE-3 cells were treated or pre-treated with GCDCA (200 µmol/L), MOTS-c (15, 30, 60 µmol/L), the multidrug resistance protein 2 (MRP2) inhibitor Probenecid (500 µmol/L), and the nuclear factor erythroid 2-related factor 2 (Nrf2) inhibitor ML385 (10 µmol/L). Cell proliferation was assessed by CCK-8 method. Lactate dehydrogenase (LDH) levels in the culture medium were measured by biochemical method. Cell apoptosis rates were determined by flow cytometry. MRP2 messenger RNA (mRNA) levels were detected by real-time quantitative polymerase chain reaction (RT-qPCR). MRP2 and Nrf2 protein expression levels were analyzed by Western blotting. Results As the concentration of GCDCA increased, the proliferation activity of THLE-3 cells gradually decreased, while LDH activity in the culture medium and apoptosis levels increased, and the expression levels of MRP2 in the cells decreased (all P<0.05). Treatment with 30 and 60 µmol/L MOTS-c significantly enhanced the proliferation activity of THLE-3 cells exposed to GCDCA, upregulated the expression of MRP2 and Nrf2, and reduced LDH activity and apoptosis levels (all P<0.05). Co-treatment with Probenecid partially reversed the protective effects of MOTS-c on GCDCA-induced THLE-3 cells injury, while co-treatment with ML385 partially inhibited the induction of MRP2 expression by MOTS-c in THLE-3 cells exposed to GCDCA. Conclusions MOTS-c may alleviate GCDCA-induced injury in human hepatocytes (THLE-3 cells), and its mechanism may be related to the upregulation of MRP2 expression mediated by Nrf2.

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.

BACKGROUND:At present,open reduction and internal fixation and minimally invasive needle aspiration are commonly used in patients with Sanders types Ⅱ and Ⅲ calcaneal fractures.However,there is little comparison between the clinical efficacy of the two methods and high-level clinical evidence is still available. OBJECTIVE:To compare the curative effect of Sanders types Ⅱ and Ⅲ calcaneal fractures treated by three-dimensional digital model-assisted minimally invasive needle penetration and tarsal sinus incision and manual reduction and internal fixation with steel plate. METHODS:From January 2021 to October 2022,80 patients with Sanders types Ⅱ and Ⅲ calcaneal fractures who were treated in the Department of Orthopedics,Cangzhou Hospital of Integrated Traditional Chinese and Western Medicine in Hebei Province were randomly divided into control group(40 cases)and observation group(40 cases).The control group was treated with manual reduction and internal fixation with steel plate through the traditional tarsal sinus incision,while the observation group was treated with a three-dimensional digital model assisted with minimally invasive needle penetration fixation.The operation time,blood loss,hospitalization time and fracture healing time of the two groups were recorded.The changes in Maryland score,AO-FAS score,pain visual analog scale score,quality of life score(SF-36 score),and imaging parameters(B?hler angle,Gissane angle,calcaneal length,width and height)were observed before and 12 months after operation in the two groups.The complications during the follow-up were recorded. RESULTS AND CONCLUSION:(1)Operation time,blood loss,hospitalization time and fracture healing time in the observation group were lower than those in the control group(all P<0.05).(2)The Maryland score,AO-FAS score,SF-36 score,B?hler angle,Gissane angle,calcaneal length and height of the two groups after treatment were significantly higher than those before treatment(all P<0.05).Visual analog scale score and calcaneal width were significantly lower than those before treatment(all P<0.05).(3)After 12 months of follow-up,the incidence of complications in the observation group was lower than that in the control group(all P<0.05).(4)In conclusion,the treatment of Sanders types Ⅱ and Ⅲ calcaneal fractures with three-dimensional digital model-assisted minimally invasive needle penetration fixation can significantly improve the operation time,bleeding volume and other perioperative indicators,and can reduce the occurrence of multiple complications.The recovery of ankle function,relief of pain symptoms,and improvement of quality of life are equivalent to traditional therapy.

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.

Objective: To explore the intervention effect of group counseling integrating teadrinking on depression, social avoidance and distress, coping styles and selfesteem among college students, so as to provide references for promoting the psychological health of students. Methods: From March to June 2021, a convenience sampling method was used to recruit 46 college students from a university in Nanjing for intervention project. There were 23 students in intervention group and control group, respectively. The intervention was conducted for 2.5 hours per week across a 6 week period. The intervention group received two sessions of group counseling that incorporated teadrinking experience, and the sessions involved tea knowledge explanation, observation and learning, embodied experience, emotional expression, interpersonal assistance and emotional support, cultural customs and life integration. After the intervention was completed, the control group received onetime group counseling that integrated teadrinking. The Wilcoxon difference test and Mann-Whitney U test were performed to compare the scores of each scale within and between the groups, and the χ2 test was used to compare the detection rates. Results: There were no statistically significant differences in the scores of positive coping, negative coping, selfesteem, social avoidance and distress between the intervention group and the control group (Z=-1.20, -0.33, -0.35, 1.31,P>0.05). There were statistically significant differences in positive coping styles, selfesteem, social avoidance and distress between the intervention group and the control group after the intervention(27.70±5.60，22.05±4.30；30.52±3.63，28.27±4.06；7.43±7.38，13.64±6.79) (Z=-3.31, -2.10, 3.22, P<0.05). The intervention group showed statistically significant differences in social avoidance and distress scores before and after the intervention(11.96±7.47,7.43±7.38) (Z=-2.88), and the depression detection rate decreased(60.9%，30.4%) (χ2=4.29) (P<0.05). There were no statistically significant differences in positive coping, negative coping, selfesteem, social avoidance and distress scores, and depression detection rate between the control group before and after the intervention (Z/χ2=-0.28, -0.42, -1.24, -1.25；1.39, P>0.05). The followup results 1year later showed that there was a statistically significant difference in social avoidance and distress(6.57±6.21,14.16±9.22), and in the detection rates of depression(21.7%,52.2%) between the intervention group and the control group (Z/χ2=2.70,4.57,P<0.05). Conclusions Group counseling integrating teadrinking could improve interpersonal relationships, emotional states, selfesteem levels and coping strategies among college students. Group psychological counseling that incorporates teadrinking can be adopted to improve the mental health status of college students.

Ferroptosis is a novel form of programmed cell death that relies on the accumulation of intracellular iron ions,causing irreversible damage to cell membranes through extensive lipid peroxidation,ultimately leading to cell death.Ferroptosis is closely associated with various neurodegenerative diseases.The ferroptosis of glial cells can regulate neuronal death by inducing neuroinflammation and affecting oxidative stress,thereby exacerbating the progression of neu-rodegenerative diseases.This review summarizes how ferroptosis occurs in different types of glial cells and its impact on neurons,aiming to deeply understand the effects of glial cell ferroptosis on neurodegenerative diseases and explore the po-tential therapeutic applications of inhibiting this process in treatment.

"Chinese model" of organ donation and transplantation in China has won acclaims from all over the world. Current contradictions between unbalanced and inadequate development of organ donation and transplantation and surging public demands for transplant services remain serious. And an acute shortage of donated organs is still the greatest difficulty. Improving organ donation rate per million population (PMP) and organ utilization rate has been a great challenge for organ donation teams in China. This review summarized the relevant experiences of Second Affiliated Hospital of Guangxi Medical University in fostering organ donation culture atmosphere and connotation to accelerate the high-quality development of organ donation. It was intended to provide references for disciplined construction of other organ donation management teams and promote the development of organ donation and transplantation in China.

OBJECTIVE To evaluate the economics of serplulimab combined with chemotherapy regimens for the first-line treatment of extensive-stage small cell lung cancer （ES-SCLC） from the perspective of health system in China. METHODS A partitioned survival model was constructed based on the ASTRUM-005 clinical trial and related literature data， with a model simulation time frame of 10 years and a 3-week cycle， and both cost and utility values were discounted using a 5% discount rate. The quality-adjusted life year （QALY） was used as a model output indicator and the incremental cost-effectiveness ratio （ICER） was calculated to evaluate the economics of serplulimab combined with chemotherapy regimens （serplulimab group） versus chemotherapy alone regimens （chemotherapy alone group） for the first-line treatment of ES-SCLC. One-way sensitivity analysis and probabilistic sensitivity analysis were used to verify the robustness of the results of the base-case analysis and to conduct a scenario analysis for the serplulimab patient assistance program. RESULTS The results of the base-case analysis showed that compared with chemotherapy alone group， ICER of serplulimab group was 758 690.27 yuan/QALY， which was higher than 3 times China’s per capita gross domestic product （GDP） in 2022 as the willingness-to-pay （WTP） threshold. The results of the scenario analysis showed that compared with chemotherapy alone group， the ICER of serplulimab group was 172 275.74 yuan/QALY， which was below above WTP threshold. The one-way sensitivity analysis showed that the progress-free survival utility value， serplulimab price and so on had a significant impact on the model results. The results of the probabilistic sensitivity analysis showed that the probability of the serplulimab group being economic was 0 when the serplulimab patient assistance program was not considered， but 100% when the patient assistance program was considered. CONCLUSIONS At a WTP threshold of 3 times China’s per capita GDP in 2022， the serplulimab group is no cost-effectiveness compared to the chemotherapy alone group； however， this result is reversed when the patient assistance program is taken into account.

Cholesterol is an important precursor of many endogenous molecules. Disruption of cholesterol homeostasis can cause many pathological changes, leading to liver and cardiovascular diseases. CYP1A is widely involved in cholesterol metabolic network, but its exact function has not been fully elucidated. Here, we aim to explore how CYP1A regulates cholesterol homeostasis. Our data showed that CYP1A1/2 knockout (KO) rats presented cholesterol deposition in blood and liver. The serum levels of low-density lipoprotein cholesterol, high-density lipoprotein cholesterol and total cholesterol were significantly increased in KO rats. Further studies found that the lipogenesis pathway (LXRα-SREBP1-SCD1) of KO rats was activated, and the key protein of cholesterol ester hydrolysis (CES1) was inhibited. Importantly, lansoprazole can significantly alleviate rat hepatic lipid deposition in hypercholesterolemia models by inducing CYP1A. Our findings reveal the role of CYP1A as a potential regulator of cholesterol homeostasis and provide a new perspective for the treatment of hypercholesterolemia.
