The concept of a community of common health for mankind aims to work with various countries to safeguard the lives and health of people worldwide. Against this backdrop， the international dissemination of traditional Chinese medicine （TCM） has become a significant topic. From October 2022 to November 2023， an anthropological fieldwork and participant observation lasting over a year was conducted in Malaysia， aiming to explore pathways for international dissemination and sharing of TCM under the concept of a community of common health for mankind through collected materials. TCM played a pivotal role in constructing the community of common health for mankind， and its unique value offers precious Chinese wisdom and strength to global healthcare undertakings. Under the initiative of the “Silk Road of Health，” the internationalization of TCM has accelerated， achieving rooted growth and wisdom sharing particularly in Malaysia and other countries along the “Belt and Road.” Facing global challenges， the sharing pathways of TCM in Malaysia became increasingly clear. Through in-depth cooperation with Chinese TCM universities， Malaysia provided valuable experience to global TCM education collaboration. With the in-depth advancement of the “Silk Road of Health” construction， the sharing pathways for TCM in Malaysia and globally demonstrated diversified and systematic characteristics， contributing greater strength for constructing a community of common health for mankind.

Objective To investigate the therapeutic effect and underlying mechanism of piceatannol against hepatic ischemia-reperfusion injury (HIRI) in fatty liver. Methods A mouse model of fatty liver combined with HIRI was established, and experimental animals were assigned into four groups: sham operation group, fatty liver HIRI group, fatty liver HIRI + piceatannol group, and fatty liver HIRI + piceatannol + ML385 group (n=5). Serum levels of alanine transaminase (ALT), aspartate transaminase (AST) and lactate dehydrogenase (LDH) were detected in each group. Hepatic tissue injury was evaluated by hematoxylin-eosin staining. Biochemical assays were performed to measure the contents of malondialdehyde (MDA), glutathione (GSH) and superoxide dismutase (SOD). Reactive oxygen species (ROS) were quantified using the DHE fluorescent probe method, while the expression of 4-hydroxynonenal (4-HNE) was determined via immunohistochemical staining. Western blot was adopted to detect the protein expression of glutathione peroxidase 4 (GPX4), acyl-CoA synthetase long-chain family member 4 (ACSL4), heme oxygenase-1 (HO-1) and nuclear factor E2-related factor 2 (Nrf2). Primary mouse hepatocytes were isolated and cultured in vitro. After treatment with palmitic acid, an hypoxia/reoxygenation (H/R) model was established. Cellular experiments were divided into control group, steatosis H/R group, steatosis H/R + piceatannol group, and steatosis H/R + piceatannol + ML385 group. Calcein-AM/PI dual staining was used to observe cell viability, C11 BODIPY staining was used to determin lipid peroxidation levels, and DCFH-DA fluorescent probe was utilized to test intracellular ROS levels. Western blot was used to detect the protein abundances of GPX4, ACSL4, HO-1 and Nrf2, and real-time fluorescence quantitative polymerase chain reaction was applied to quantify their corresponding messenger RNA (mRNA) expression levels. Results Compared with the sham operation group, the levels of ALT, AST and LDH, liver injury score, DHE positive rate, MDA level and 4-HNE level increased, the levels of GSH and SOD decreased, the relative expression level of ACSL4 protein increased, and the relative expression levels of GPX4, Nrf2 and HO-1 proteins decreased in the fatty liver HIRI group; compared with the fatty liver HIRI group, the levels of ALT, AST and LDH, liver injury score, DHE positive rate, MDA level and 4-HNE level decreased, the levels of GSH and SOD increased, the relative expression level of ACSL4 protein decreased, and the relative expression levels of GPX4, Nrf2 and HO-1 proteins increased in the fatty liver HIRI + piceatannol group; compared with the fatty liver HIRI + piceatannol group, the levels of ALT, AST and LDH, liver injury score, DHE positive rate, MDA level and 4-HNE level increased, the levels of GSH and SOD decreased, the relative expression level of ACSL4 protein increased, and the relative expression levels of Nrf2 and HO-1 proteins decreased in the fatty liver HIRI + piceatannol + ML385 group (all P<0.05). Compared with the control group, the mean fluorescence intensity of DCFH-DA and MDA level increased, the levels of GSH and SOD decreased, the proportion of oxidized lipids increased, the protein and mRNA expression levels of ACSL4 increased, and the protein and mRNA expression levels of GPX4, HO-1 and Nrf2 decreased in the steatosis H/R group; compared with the steatosis H/R group, the mean fluorescence intensity of DCFH-DA and MDA level decreased, the levels of GSH and SOD increased, the proportion of oxidized lipids decreased, the relative protein and mRNA expression levels of ACSL4 decreased, and the relative protein and mRNA expression levels of GPX4, HO-1 and Nrf2 increased in the steatosis H/R + piceatannol group; compared with the steatosis H/R + piceatannol group, the mean fluorescence intensity of DCFH-DA and MDA level increased, the levels of GSH and SOD decreased, the proportion of oxidized lipids increased, the relative protein and mRNA expression levels of ACSL4 increased, and the relative protein and mRNA expression levels of GPX4, HO-1 and Nrf2 decreased in the steatosis H/R + piceatannol + ML385 group (all P<0.05). Conclusions Piceatannol relieves HIRI in fatty liver by activating the Nrf2/HO-1 signaling pathway to suppress ferroptosis in hepatocytes.

[摘 要] 目的：探究环状RNA（circRNA）调控舌鳞状细胞癌（TSCC）顺铂（CDDP）耐药的机制。方法：本研究以TSCC化疗敏感CAL27细胞与耐药CAL27-res细胞为研究对象，RT-qPCR检测两种细胞内hsa_circ_0034762的表达量差异，流式细胞术检测细胞凋亡率，Western blotting检测自噬相关蛋白p62及LC3-Ⅱ/LC3-Ⅰ比值，透射电镜观察自噬小体的数量，双萤光素酶报告实验检测hsa_circ_0034762与miR-17-3p的结合关系，荧光原位杂交实验检测二者在细胞中的共定位，敲低hsa_circ_0034762联合抑制miR-17-3p进行功能回复实验。结果：相比亲本化疗敏感细胞，TSCC耐药细胞CAL27-res自噬水平显著提升，表现为自噬小体数量增加、LC3-Ⅱ/LC3-Ⅰ比值升高及p62蛋白表达降低。hsa_circ_0034762在TSCC耐药组织及CAL27-res细胞中高表达。敲低hsa_circ_0034762后，CAL27-res细胞凋亡率升高，自噬小体数量减少，p62蛋白表达增加，LC3-Ⅱ/LC3-Ⅰ比值降低（均P < 0.05）。双萤光素酶报告实验与荧光原位杂交实验发现hsa_circ_0034762与miR-17-3p存在靶向结合作用。抑制miR-17-3p可部分逆转hsa_circ_0034762敲低所致的促凋亡及抑制自噬效应。结论：hsa_circ_0034762在TSCC耐药细胞及组织中高表达。敲低hsa_circ_0034762可能通过miR-17-3p抑制细胞自噬并促进细胞凋亡，从而降低TSCC细胞的化疗耐药性。

Red doctor culture represents a special cultural form developed by people of all ethnic groups under the leadership of the Communist Party of China during the revolution， construction， and development processes. It closely unites people of all ethnic groups in the historical context of realizing the great rejuvenation of the Chinese nation， possessing great significance for strengthening the sense of community for the Chinese nation. This article adopted ethno-symbolism as an analytical framework， revealing the internal mechanism of red doctor culture in activating the sense of community. The research indicated that red doctor culture adhered to the purpose of serving people’s health wholeheartedly， constructing a health community where all ethnic groups share weal and woe. It firmly upheld the mission of inheriting fine traditional Chinese culture and promoted the integration of traditional Chinese and Western medicine， shaping a cultural community that shares honor and disgrace. Red doctor workers and people of all ethnic groups worked in unity and cooperation， jointly safeguarding life safety and national security in critical moments， thereby building a security community forged through shared struggles. Red doctor culture embodied firm ideals and beliefs， uniting all ethnic groups into a community of shared future bound by common convictions. On this basis， this paper proposed practical paths to strengthen the sense of community for the Chinese nation through red doctor culture， aiming to realize effective transformation of red health resources from historical memory to contemporary identity.

ObjectiveTo investigate the association between perioperative troponin elevation and the occurrence of major adverse cardiac events （MACE） in elderly patients with colorectal cancer， and to provide evidence for optimizing perioperative management strategies. MethodsA total of 268 elderly patients aged 70 years and above who underwent colorectal cancer surgery were retrospectively enrolled. They were divided into a conventional management group （87 cases） and a standardized management group （181 cases） according to the perioperative management strategy. Binary logistic regression analysis was used to identify the independent influencing factors for the occurrence of major adverse cardiac events. P-value ≤ 0.05 was considered statistically significant. ResultsAmong the 268 patients， the overall incidence of perioperative major adverse cardiac events was 4.5% （12/268）. The total incidence of major adverse cardiac events in the conventional management group was 8.0% （7/87）， which was significantly higher than that in the standardized management group （2.8%， 5/181；P=0.05）. Specifically， the incidences of myocardial infarction， heart failure， and death in the conventional management group were markedly higher than those in the standardized management group （8.0% vs. 2.2%， 4.6% vs. 0.6%， 4.6% vs. 0.6%， all P＜0.05）， while no significant difference was observed in the incidence of cardiogenic shock between the two groups （1.1% vs. 1.1%， P＞0.05）. Postoperative troponin elevation was significantly associated with the occurrence of perioperative major adverse cardiac events except for cardiogenic shock （including total cardiovascular events， myocardial infarction， heart failure， and death） （all P＜0.05）， and it was identified as a strong independent risk factor for perioperative major adverse cardiac events in these patients. ConclusionCompared with conventional management， standardized perioperative troponin management can significantly reduce the risks of myocardial infarction， heart failure， and death， and also exhibits a potential protective trend against cardiogenic shock. Postoperative troponin elevation is a strong independent risk factor for the occurrence of perioperative major adverse cardiac events.

ObjectiveTo analyze the clinical manifestations， diagnostic approaches， treatment strategies， and prognostic outcomes of uterine arteriovenous fistula （UAVF）. MethodsWe retrospectively analyzed 6 patients with confirmed UAVF admitted to the Department of Gynecology， the Eighth Affiliated Hospital of Sun Yat-sen University， between January 2010 and December 2023. We summarized the clinical data of the cohort， including age， gravidity， chief complaints， treatment regimens， and postoperative follow-up outcomes， and explored the clinical efficacy and safety of ultrasound-guided microwave ablation for UAVF in conjunction with a literature review. ResultsThe patients were aged 26-44 years， with a mean age of （34.33±6.12） years and a median age of 33.5 years. All patients were initially screened via color Doppler ultrasound and definitively diagnosed by imaging modalities including uterine arteriography， computed tomography， and magnetic resonance imaging. The median gravidity was 4（4，6）， with 5 patients having a history of ≥2 pregnancies. Five patients had a history of intrauterine instrumentation， among whom 4 had undergone ≥2 procedures. Regarding clinical presentations， 3 patients presented with abnormal vaginal bleeding （2 with massive hemorrhage）， 2 were asymptomatic with abnormalities detected only on imaging， and 1 reported lower abdominal pain. In terms of management， 1 patient with recurrence after uterine artery embolization （UAE） underwent ultrasound-guided microwave ablation； 1 received UAE alone； 2 patients with concomitant retained products of conception underwent hysteroscopic mechanical morcellation （1 developed massive hemorrhage 10 hours postoperatively， which was successfully controlled with uterine balloon tamponade）； 1 underwent focal lesion resection； and 1 underwent total hysterectomy. All 6 patients achieved favorable therapeutic outcomes. ConclusionAbnormal vaginal bleeding is the most typical clinical manifestation of UAVF， and digital subtraction angiography of the uterine arteries is recognized as the gold standard for definitive diagnosis. Emergency UAE is indicated for patients presenting with acute massive hemorrhage and hemodynamic instability. For patients with failed UAE or post-UAE recurrence who desire uterine and fertility preservation， ultrasound-guided microwave ablation represents a safe， effective， and novel minimally invasive therapeutic option.

Objective Jejunal interposition is an important option for restoring gastrointestinal continuity in patients with complex esophageal cancer in whom the stomach is unavailable for reconstruction due to previous gastrectomy, tumor involvement, failed gastric conduit, or other constraints. Although the jejunum offers a caliber similar to the esophagus, a rich blood supply, and preserved peristaltic function, anatomical variations in mesenteric length and vascular arcades render long-segment and high-level reconstruction susceptible to excessive tension, mesenteric torsion, venous congestion, and inadequate distal perfusion. This consensus aims to provide standardized recommendations for the application of jejunal interposition in this specific patient population. Methods This consensus was developed in accordance with the WHO Handbook for Guideline Development and Chinese national guideline development standards, with reference to the Appraisal of Guidelines for Research & Evaluation Ⅱ(AGREE Ⅱ), Reporting Items for Practice Guidelines in Healthcare (RIGHT), and Scientific, Transparent and Applicable Rankings (STAR) checklists. The project was registered on the international practice guidelines registry platform (PREPARE-2026CN1384). The working group systematically searched Chinese and English evidence addressing 12 clinical questions. Evidence was graded using the Oxford Centre for Evidence-Based Medicine (OCEBM) 2009 system, with structured appraisal of risk of bias, inconsistency, indirectness, and imprecision. Recommendations were formulated through two rounds of Delphi surveys and a face-to-face consensus meeting, with an agreement threshold of ≥75%. Results The consensus generated 12 recommendations covering indications, selection between jejunum and colon, preoperative assessment, surgical approach and reconstruction route, pedicled jejunal interposition (PJI), supercharged pedicled jejunal interposition (SPJ), indocyanine green (ICG) perfusion assessment, perioperative nutrition, management of anastomotic leakage, long-term follow-up, and special treatment scenarios. Given that the available direct evidence is predominantly derived from single-center retrospective cohorts and case series, recommendations extrapolated from general esophagectomy or other gastrointestinal surgical evidence are deliberately phrased with caution. Conclusion Jejunal interposition is a safe and effective approach for digestive tract reconstruction in patients with complex esophageal cancer in whom the stomach is unavailable. This consensus emphasizes that clinical decision-making should be individualized based on the patient's prior treatment history, reconstruction height, vascular anatomy, technical availability, and institutional experience in the Chinese context.

Background: The association of changes in metabolic syndrome (MetS) with cognitive function remains unclear. We explored this association using prospective and Mendelian randomization (MR) studies. Methods: MetS components including high-density lipoprotein cholesterol (HDL-C), systolic blood pressure (SBP), waist circumference (WC), fasting plasma glucose (FPG), and triglycerides were measured at baseline and two follow-ups, constructing a MetS index. Immediate, delayed memory recall, and cognitive function along with its dimensions were assessed by immediate 10- word recall test (IWRT) and delayed 10-word recall test (DWRT), and mini-mental state examination (MMSE), respectively, at baseline and follow-ups. Linear mixed-effect model was used. Additionally, the genome-wide association study (GWAS) of MetS was conducted and one-sample MR was performed to assess the causality between MetS and cognitive function. Results: Elevated MetS index was associated with decreasing annual change rates (decrease) in DWRT and MMSE scores, and with decreases in attention, calculation and recall dimensions. HDL-C was positively associated with an increase in DWRT scores, while SBP and FPG were negatively associated. HDL-C showed a positive association, whereas WC was negatively associated with increases in MMSE scores, including attention, calculation and recall dimensions. Interaction analysis indicated that the association of MetS index on cognitive decline was predominantly observed in low family income group. The GWAS of MetS identified some genetic variants. MR results showed a non-significant causality between MetS and decrease in DWRT, IWRT, nor MMSE scores. Conclusion Our study indicated a significant association of MetS and its components with declines in memory and cognitive function, especially in delayed memory recall.

Objective Investigate the prevalence and epidemiological characteristics of flatfoot among a sample of adolescents(grade 3,5 and 7)in the Northeastern Chongqing,analyze the influencing factors,to provide a scientific basis for selecting intervention strategies.Methods Utilizing plantar optical observation mirrors and questionnaires,a flatfoot screening was conducted among grade 3,5 and 7 school-aged adolescents from 10 urban and rural schools in Wanzhou District,Chongqing.Relevant parameters were recorded,and uni-variate logistic regression analysis was performed considering gender,genetics,BMI,exercise duration,foot-wear,history of ankle trauma,awareness of risks,medical consultation history,and knowledge of preventive measures for flatfoot prevalence.Variables with statistically significant differences in the univariate logistic a-nalysis were included in the multivariate logistic regression analysis.Results In a sample of 5 058 school-age adolescents,2 163 were diagnosed with flatfoot,yielding a prevalence rate of 42.76%(2 163/5 058).Urban and rural areas difference:urban areas had a rate of 43.70%(1 444/3 304),while rural areas had a rate of 40.99%(719/1 754),no statistically significant difference was found between the two(χ2=3.334,P=0.068).Gender difference:males had a rate of 45.56%(1 212/2 660),and females had a rate of 39.66%(951/2 398),the prev-alence rate was higher in males than in females,with a statistically significant difference(χ2=17.730,P<0.001).Grade difference:the prevalence rate in grade 3 was 49.45%(822/1 662),in grade 5 was 42.78%(727/1 699),and in grade 7 was 36.18%(614/1 697),there was a statistically significant among different grades(χ2=60.473,P<0.001),while the prevalence rate in grade 3 was significantly higher than that in grade 5 and 7,and it showed a decreasing trend with the increase of the students'grade level(χ2 trend=24.223,P<0.001).Genetic differences:the proportion of individuals with a positive genetic predisposition to flat feet was 15.53%(336/2 163),the influence of genetics on the occurrence of flat feet was statistically significant(χ2=70.232,P<0.001);furthermore,there was a higher genetic tendency towards severe flatfoot,with statistically significant difference(χ2trend=44.976,P<0.001).BMI difference:comparison of flatfoot severity across differ-ent BMI strata showed a significant difference(χ2trend=21.118,P=0.002),indicating that varying BMI levels affect the prevalence of flatfoot.Multivariate logistic regression analysis showed that gender,genetics,and BMI(18.5-<25.0 kg/m2)were the influencing factors of flatfoot among adolescents in Northeastern Chongqing(P<0.05).Conclusion The incidence of flatfoot among school-age adolescents decreases with in-creasing grade,with lower rates among girls than boys,and there is a genetic predisposition.Most flatfoot are mild,and BMI is a high-risk factor.Early intervention should be implemented for flatfoot in adolescents.

Purpose: Neuroendocrine prostate cancer (NEPC) represents a particularly aggressive subtype of prostate cancer with a challenging prognosis. The purpose of this investigation is to craft and confirm the reliability of nomograms that can accurately forecast the 1-, 3-, and 5-year overall survival (OS) and cancer-specific survival (CSS) rates for individuals afflicted with NEPC. Materials and Methods: Data pertaining to patients diagnosed with NEPC within the timeframe of 2010 to 2020 was meticulously gathered and examined from the Surveillance, Epidemiology, and End Results Program (SEER). To predict OS and CSS, we devised and authenticated two distinct nomograms, utilizing predictive variables pinpointed through both univariate and multivariate Cox regression analyses. Results: The study encompassed 393 of NEPC patients, who were systematically divided into training and validation cohorts at a 2:1 ratio. Key prognostic factors were isolated, verified, and integrated into the respective nomograms for OS and CSS. The performance metrics, denoted by C-indices, stood at 0.730, 0.735 for the training set, and 0.784, 0.756 for the validation set. The precision and clinical relevance of the nomograms were further corroborated by the analysis of receiver operating characteristic curves, calibration plots, and decision curve analyses. Conclusions The constructed nomograms have demonstrated impressive efficacy in forecasting the 1-, 3-, and 5-year OS and rates for patients with NEPC. Implementing these predictive tools in clinical settings is anticipated to considerably enhance the care and treatment planning for individuals diagnosed with this aggressive form of prostate cancer, thus providing tailored and more precise prognostic assessments.
