Since Li Dongyuan formally proposed the concept of "wind medicinals" （Feng Yao），their clinical application has been highly valued by physicians throughout history. However，influenced by the evolution of the term and connotation of "wind medicinals" in modern times，its conceptual understanding，leading to a decline in clinical utilization. Since the new century，Professor Wang Mingjie has integrated LIU Wanxu's sweat pore （Xuanfu） theory into the reinterpretation of wind medicinals，proposing the "Xuanfu-dredging wind medicinal theory"， which has gained widespread recognition in academic circles，revitalizing their clinical application. This study traces the origin of the Xuan-dredging wind medicinals theory and reviews their current functions and clinical applications，finding that the theoretical framework is preliminarily established. Characterized by their pungent and dispersing properties，wind medicines act by opening the Xuanfu throughout the body，exerting therapeutic effects such as dispelling pathogens，resolving stagnation，and enhancing treatments like blood-activation，spleen-fortification，and heat-clearing. They are widely used，showing advantages in treating systemic diseases including ophthalmic and cardiovascular/cerebrovascular disorders. Modern pharmacological research indicates preliminary consensus on hypotheses of cerebral，intestinal，hepatic，and renal Xuanfu. studies on formulas （e.g.，Qufeng Tongqiao Fang），single herbs （e.g.，Mahuang and Gegen），and active constituents （e.g.，tetramethylpyrazine） provide evidence that wind medicines improve key mechanisms like blood-brain barrier function and cerebral microcirculation （material basis of cerebral Xuanfu），supporting their use in brain disorders （e.g.，cerebral ischemia，depression）. Despite clinical and pharmacological support，the clinical application system for wind medicines remains incomplete. Future efforts should focus on high-quality clinical research and mechanistic studies to establish personalized application systems，enhance Xuanfu opening practices，and ensure the effectiveness and safety of wind medicines.

ObjectiveTo investigate the safety and feasibility of intra-biliary drainage tube placement after laparoscopic common bile duct exploration in elderly patients with choledocholithiasis， and to provide more options for surgical procedures in the clinical management of elderly patients with choledocholithiasis. MethodsA retrospective analysis was performed for the clinical data of 52 elderly patients with choledocholithiasis who were admitted to Department of Hepatobiliary Surgery， Affiliated Dalian Friendship Hospital of Dalian Medical University， from November 2021 to October 2024. According to the biliary drainage method after surgery， the patients were divided into internal drainage group with 24 patients and T-tube drainage group with 28 patients， and there were 19 patients in each group after propensity score matching. The two groups were compared in terms of perioperative parameters and postoperative complications. The Wilcoxon rank-sum test was used for comparison of continuous data between two groups， and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. ResultsCompared with the T-tube drainage group， the internal drainage group had a significantly shorter length of postoperative hospital stay and a significantly lower volume of postoperative bile loss （Z=-2.845 and -5.633， both P<0.05）， while there were no significant differences between the two groups in time of operation， intraoperative blood loss， and drainage tube indwelling time （all P>0.05）. There were no significant differences between the two groups in postoperative bile leak， stone recurrence， biliary stricture， and drainage tube-related complications， and the internal drainage group had a significantly lower total complication rate than the T-tube drainage group ［1 （5.3%） vs 7 （36.8%）， P<0.05］. ConclusionFor elderly patients with choledocholithiasis， intra-biliary drainage tube placement after laparoscopic common bile duct exploration can shorten the length of postoperative hospital stay， reduce bile loss， and lower the incidence rate of postoperative complications， thereby helping to accelerate postoperative recovery.

OBJECTIVES: To investigate the effect of orexin-A-mediated regulation of ionotropic glutamate receptors for promoting motor function recovery in rats with spinal cord injury (SCI). METHODS: Thirty-six newborn SD rats (aged 7-14 days) were randomized into 6 groups (n=6), including a normal control group, a sham-operated group, and 4 SCI groups with daily intrathecal injection of saline, DNQX, orexin-A, or orexin-A+DNQX for 3 consecutive days after PCI. Motor function of the rats were evaluated using blood-brain barrier (BBB) score and inclined plane test 1 day before and at 1, 3, and 7 days after SCI. For patch-clamp experiment, spinal cord slices from newborn rats in the control, sham-operated, SCI, and SCI+orexin groups were prepared, and ventral horn neurons were acutely isolated to determine the reversal potential and dynamic indicators of glutamate receptor-mediated currents under glutamate perfusion. RESULTS: At 3 and 7 days after SCI, the orexin-A-treated rats showed significantly higher BBB scores and grip tilt angles than those with other interventions. Compared with those treated with DNQX alone, the rats receiving the combined treatment with orexin and DNQX had significantly higher BBB scores and grip tilt angles on day 7 after PCI. In the patch-clamp experiment, the ventral horn neurons from SCI rat models exhibited obviously higher reversal potential and greater rise slope of glutamate current with shorter decay time than those from sham-operated and orexin-treated rats. CONCLUSIONS Orexin-A promotes motor function recovery in rats after SCI possibly by improving the function of the ionotropic glutamate receptors.

Objective:To comprehensively assess the nutritional literacy among family caregivers of elderly patients with chronic heart failure (CHF), so as to provide reference for developing clinical nutrition management strategies for elderly CHF patients.Methods:This study was a descriptive qualitative research. From February to March 2025, purposive sampling was used to select 17 family caregivers of elderly CHF patients at Affiliated Hospital of Yangzhou University as research subjects for semi-structured interviews. The data was analysed using a directed content analysis approach.Results:Three themes and nine subthemes were identified, including functional nutrition literacy (lack of disease-related nutrition knowledge, difficulty in knowledge transformation and utilization, and barriers to voluntary nutritional adherence), interactive functional literacy (limited channels for accessing nutrition information, broken healthcare services, insufficient motivation for proactive communication, and demand for professional dietary guidance), and critical nutrition literacy (challenges in distinguishing information authenticity, reliance on inherent cognition for evaluation) .Conclusions:Family caregivers of elderly patients with CHF commonly lack relevant nutritional knowledge. Healthcare providers should attach importance to the education of nutrition knowledge and skills for family caregivers, establish a multidimensional nutrition education system, develop personalized nutrition guidance plans, and integrate the family-community-medical collaborative support network to systematically strengthen caregivers' understanding of disease nutrition management for elderly CHF patients and enhance their compliance with nutrition care practices.

Objective To investigate the protective effect and mechanism of schisandrin A(SA)on hydrogen peroxide(H2O2)-induced oxidative stress injury in renal tubular epithelial cells(HK-2).Methods HK-2 cells were cultured in vitro and divided into five groups:blank control group,model control group(treated with 600 μmol·L-1 H2O2 for 2 h),low-dose SA group(0.125 μmol·L-1 SA,24 h pretreatment+H2O2),medium-dose SA group(0.5 μmol·L-1 SA,24 h pretreatment+H2 O2),high-dose SA group(0.75 μmol·L-1 SA,24 h pretreatment+H2O2).The cell survival was assessed by CCK-8 assay;apoptosis level was tested by Annexin V-FITC/PI double staining;cell cycle distribution was detected by propidium iodide staining;oxidative markers(ROS,SOD,MDA,GSH,LDH)was determined with commercial kits;and apoptosis-related proteins(Bax,Bcl-2,Caspase-3,Cytochrome C)was evaluated by Western blot.Results Compared with the blank control,the model group reduced in cell viability and increased in apoptosis(P＜0.01),elevated in the ratio of G0/G1-phase cells and decreased in S-phase cells(P＜0.05),decreased in SOD activity and GSH content(P＜0.01),and increased in the levels of ROS,LDH,and MDA levels(P＜0.01).In all SA dose,cell apoptosis reduced(P＜0.01).In medium/high dose groups,the G0/G1-phase arrest reduced(P＜0.05).In high dose group,the S-phase cells ratio increased(P＜0.05).And in medium/high dose groups,ROS(P＜0.01)decreased in a dose-dependent manner.The SOD activity increased non-significantly in all SA groups.In SA medium/high dose groups,the LDH activity decreased in a dose-dependent manner.In all SA groups,GSH increased(P＜0.01)and MDA decreased,both in a dose-dependent manner.The Bax/Bcl-2 ratio significantly decreased(P＜0.05)in all SA groups.The caspase-3 activity decreased in medium/high dose group(P＜0.05);and Cytochrome C reduced in all SA groups(P＜0.05).Conclusion SA protects HK-2 cells against H2O2-induced oxidative injury by modulating oxidative stress,inhibiting apoptosis,and ameliorating cell cycle arrest.

AIM:This study aims to investigate the role of histone methyltransferase SET and MYND domain containing 2(SMYD2)in facilitating renal fibrosis through the macrophage-myofibroblast transition in diabetic kidney dis-ease(DKD).METHODS:(1)C57BL/6J mice were intraperitoneally administered 55 mg/kg of streptozotocin to induce diabetes mellitus(DM).The experimental groups were categorized as follows:normal control,DM(20 weeks),DM(28 weeks),and DM(36 weeks).Blood glucose(BG),serum creatinine(SCr)and blood urea nitrogen(BUN)levels were determined using a biochemical analyzer.Hematoxylin-eosin(HE)staining and Masson staining were performed to assess morphological and fibrotic changes in renal tissues.Western blot analysis was used to measure the protein levels of SMYD2,histone H3 lysine 4 trimethylation(H3K4me3),arginase-1,matrix metalloproteinase 9(MMP9),collagen type Ⅰ(Col Ⅰ)and α-smooth muscle actin(α-SMA).Immunofluorescence staining was conducted to examine the localization and expression of F4/80,α-SMA,SMYD2,CD86,CD206 and CD163.(2)Mouse monocyte/macrophage RAW264.7 cells were cultured in vitro and assigned to groups as follows:normal glucose(NG)+negative control siRNA(siNC),high glucose(HG)+siNC,NG+SMYD2 siRNA(siSMYD2),and HG+siSMYD2.Western blot analysis was used to assess the expression of relevant proteins.RESULTS:(1)Compared with normal control group,the levels of BG,SCr and BUN were significantly elevated in DM(28 weeks)and DM(36 weeks)groups(P＜0.05).Renal tissue exhibited tubular atro-phy,dilation,and collagen fiber deposition.The levels of H3K4me3,arginase-1,MMP9,Col Ⅰ and α-SMA proteins were up-regulated(P＜0.05).The CD86,CD206,CD163 and F4/80 were primarily localized in the interstitial macrophages of the renal tubules,α-SMA was predominantly detected in the renal interstitium,and SMYD2 was mainly expressed in renal tubular epithelial cells and the renal interstitium.(2)Compared with NG+siNC group,the protein levels of SMYD2,H3K4me3,arginase-1,CD163,Col Ⅰ,α-SMA,transforming growth factor-β1(TGF-β1)and p-Smad3 in the cells of HG+siNC group were significantly increased(P＜0.05).Knockdown of SMYD2 resulted in a reduction of these indicators(P＜0.05).CONCLUSION:The SMYD2 protein appears to facilitate renal fibrosis in DKD by promoting the macrophage-myofibroblast transition,potentially through the modulation of TGF-β1/Smad3 signaling pathway.

Objective:To explore the effect of arrhythmia in early and intermediate postoperative stages of the Fontan procedure.Methods:Patients undergoing Fontan procedure at Shanghai Children's Medical Center within 2015 to 2018 were included.Identified data obtained from retrospective，observational dataset including demographic information，patient diagnoses，baseline characteristics，operation details，ECG data，ultrasound cardiograph data，in-hospital medical intervention，in-hospital mortality，out-patient medical intervention，readmission，and complications.Results:Among the 277 children，early arrhythmia occurred in 173 cases（62.5%），medium- and long-term arrhythmia occurred in 35 cases（12.6%），and 69 cases（24.91%）had no arrhythmia，of which only 55 cases（19.9%）needed early intervention with drugs.Malignant arrhythmia was an independent predictor of poor prognosis（ OR 5.835 95% CI 1.738-19.596, P=0.004）.Among all arrhythmia，atrioventricular junction arrhythmia had the highest incidence.During the follow-up，we found that most of the arrhythmia that had occurred in the early postoperative period could return to normal in three months after the operation，while the rhythm gradually stabilized at four years after the operation，the persistent arrhythmia almost no longer returned to normal，and the normal rhythm basically did not recur.For patients who did not develop arrhythmia in the early postoperative period，the peak of new arrhythmia occurred within one year after surgery，and most of them were persistent arrhythmia. Conclusion:The development of an arrhythmia is associated with a heightened risk of subsequent failure of the Fontan circulation，especially malignant arrhythmia.However，the incidence of malignant arrhythmia is not high.In addition，most of the arrhythmias that had occurred in the early postoperative period could return to normal in three months after surgery，and the rhythm gradually stabilized in four years after surgery.While no arrhythmia in the early postoperative period，the peak of new arrhythmia occur within one year after surgery，and most of them are persistent arrhythmia.

Objective To identify candidate compounds that activate thermogenesis during cold exposure by integrating the Library of Integrated Network-Based Cellular Signatures(LINCS)with RNA expression profiles specific to cold-induced thermogenesis.Methods Gene expression profiles of interscapular brown adipose tissue(BAT)and inguinal white adipose tissue(iWAT)were generated from 8-week-old C57BL/6J mice which were housed at 5 ℃ or room temperature(23 ℃)for 7 days.The gene expression signatures of the cold-induced BAT and iWAT were compared to the LINCS dataset to predict potential candidates for testing in a cold challenge model that was intended to assess thermogenesis activation.The pharmacological potential of the identified compounds was evaluated in a cold-exposed mouse model.The core body temperature and infrared thermal imaging were collected to monitor physiological responses during cold exposure.Additionally,hematoxylin and eosin(HE)staining was used to assess morphological changes of fat cells of BAT,iWAT,and epididymal white adipose tissue(eWAT).Results The transcriptomic signatures related to cold-induced thermogenesis were obtained and the top 20 candidate compounds were identified by comparison with the LINCS dataset.Mice treated with withaferin A(WA)during the cold challenge exhibited elevated rectal temperatures and smaller adipocyte sizes compared to controls.Conclusion Our drug repurposing strategy,which connects transcriptional profiles with LINCS data,identifies potential compounds.WA enhances thermogenesis and metabolic activity in adipose tissue,which helps maintain body temperature,and improves cold tolerance during exposure to low temperatures.

Purpose To investigate the value of radiomics nomogram for the prediction of p53 abnormal in patient with endometrial carcinoma based on intratumoral and peritumoral MRI.Materials and Methods A total of 145 female patients were pathologically confirmed endometrial carcinoma who underwent pelvic MRI before treatment in Baoding First Central Hospital from January 2020 to April 2024,including 96 patients with p53 wild type and 49 with p53 abnormal.Radiomics features were extracted from both intratumoral and peritumoral regions(2 mm)in diffusion weighted imaging and equilibrium phase of dynamic contrast enhanced MRI,which were selected using least absolute shrinkage and selection operator.Three machine learning algorithms of random forest,K-nearest neighbors and extra trees were conducted to develop the intratumoral,peritumoral and intratumoral combined peritumoral radiomics models.Multivariate Logistic regression was used to constitute the clinical model and nomogram.The performance of these models was evaluated using receiver operating characteristic curve,decision curve analysis and calibration curve.Results The K-nearest neighbors model of the intratumoral combined peritumoral regions performed the best in all radiomics models,the area under the curve were 0.921 and 0.773 in the training cohorts and test cohorts.The radiomics nomogram,which was composed of age,apparent diffusion coefficient and radiomics signatures,achieved the best performance with area under the curve of 0.970 and 0.777 in the training cohorts and test cohorts,respectively.Calibration curve analysis and decision curve analysis demonstrated favorable calibration and clinical utility of the nomogram model.Conclusion The nomogram based on intratumoral and peritumoral MRI radiomics yields a favorable diagnostic value for predicting p53 abnormal in patient with endometrial carcinoma.
