OBJECTIVE To study the efficacy of Tianjiang xueshuantong pills in the treatment of coronary heart disease. METHODS In accordance with the common pathogenesis of coronary heart disease， acute myocardial ischemia model， hyperlipidemia model， blood stasis model， and carotid artery thrombosis model were established using Wistar rats or SD rats as the experimental subjects. The effects of Tianjiang xueshuantong pills administered at high， medium， and low doses （0.6， 1.2 and 2.4 g/kg） on hemodynamic parameters and myocardial enzyme markers [lactate dehydrogenase （LDH）， creatine kinase-MB （CK- MB）]， oxidative stress factors [superoxide dismutase （SOD）， malondialdehyde （MDA）， glutathione （GSH）]， inflammatory cytokines [tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， IL-1β， monocyte chemotactic protein-1 （MCP-1）， intercellular adhesion molecule-1 （ICAM-1）]， myocardial infarction percentage， serum lipid indexes [total cholesterol （TC）， triglycerides （TG）， low-density lipoprotein （LDL）， high-density lipoprotein （HDL）]， platelet aggregation function 话：022-84845240。E-mail：jiangx@tjipr.com [maximum aggregation rate （MAR）]， and thrombus formation indexes [thrombosis time， thrombus mass， thrombus protein content， plasminogen activator inhibitor-1 （PAI-1）， and tissue-type plasminogen activator （t-PA）] were evaluated in the rat models. RESULTS In myocardial ischemia tests， Tianjiang xueshuantong pills significantly reduced the percentage of myocardial infarction and the levels of CK-MB， LDH， MDA， GSH， IL-6， TNF-α， IL- 1β， and MCP-1 in serum （P＜0.05 or P＜0.01）. In hyperlipidemia tests， high dose of Tianjiang xueshuantong pills significantly reduced the serum levels of TC， LDL and significantly increased the level of HDL in rats after 2 weeks and 4 weeks of administration. In blood stasis tests， different doses of Tianjiang xueshuantong pills significantly reduced MAR of rats （P＜0.01）. In artery thrombosis tests， high dose of Tianjiang xueshuantong pills significantly prolonged the time of thrombosis formation （P＜ 0.01）， significantly reduced the weight and protein content of thrombus and the level of PAI-1 in serum （P＜0.01）. CONCLUSIONS Tianjiang xueshuantong pills exert therapeutic effects on coronary heart disease through multi-dimensional synergistic actions， including anti-myocardial ischemia， lipid-lowering， and anti-thrombotic effects.

Male infertility has become a global concern, accounting for 20-70% of infertility. Dysfunctional spermatogenesis is the most common cause of male infertility; thus, treating abnormal spermatogenesis may improve male infertility and has attracted the attention of the medical community. Mitochondria are essential organelles that maintain cell homeostasis and normal physiological functions in various ways, such as mitochondrial oxidative phosphorylation (OXPHOS). Mitochondrial OXPHOS transmits electrons through the respiratory chain, synthesizes adenosine triphosphate (ATP), and produces reactive oxygen species (ROS). These mechanisms are vital for spermatogenesis, especially to maintain the normal function of testicular Sertoli cells and germ cells. The disruption of mitochondrial OXPHOS caused by external factors can result in inadequate cellular energy supply, oxidative stress, apoptosis, or ferroptosis, all inhibiting spermatogenesis and damaging the male reproductive system, leading to male infertility. This article summarizes the latest pathological mechanism of mitochondrial OXPHOS disorder in testicular Sertoli cells and germ cells, which disrupts spermatogenesis and results in male infertility. In addition, we also briefly outline the current treatment of spermatogenic malfunction caused by mitochondrial OXPHOS disorders. However, relevant treatments have not been fully elucidated. Therefore, targeting mitochondrial OXPHOS disorders in Sertoli cells and germ cells is a research direction worthy of attention. We believe this review will provide new and more accurate ideas for treating male infertility.

ObjectiveTo investigate the effect of the multidisciplinary team （MDT） management model in improving the prognosis of patients with cirrhotic portal hypertension. MethodsA total of 86 patients with cirrhotic portal hypertension who were admitted to Shenzhen Third People’s Hospital from May 2022 to July 2024 were enrolled， and according to whether the MDT treatment regimen was implemented， they were divided into execution group with 51 patients and non-execution group with 35 patients. Baseline clinical data were collected， and the patients were observed in terms of gastrointestinal bleeding， hepatic encephalopathy， liver cancer， and death from admission to the end of follow-up （January 2025）. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Wilcoxon rank-sum test was used for comparison of non-normally distributed continuous data between two groups； the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups. The Kaplan-Meier method was used to plot survival curves for the cumulative incidence rates of endpoint events （gastrointestinal bleeding， hepatic encephalopathy， liver cancer， and death）， and the Log-rank test was used for comparison between groups. The Cox proportional-hazards regression model analysis was used to investigate the effect of MDT management on the prognosis of patients. ResultsThere were significant differences between the execution group and the non-execution group in diameter of the portal vein （t=1.216， P=0.017） and ascites （χ²=4.515， P=0.034） at baseline. The patients were followed up for 14.6±6.2 months， and the survival curve analysis showed that there was a significant difference in the cumulative incidence rate of gastrointestinal bleeding between the two groups （χ²=4.573， P=0.024）， while there were no significant differences in the incidence rates of other outcome events between the two groups （all P>0.05）. The Cox regression analysis showed that the execution group had a reduced risk of gastrointestinal bleeding （hazard ratio=0.262， 95% confidence interval： 0.110 — 0.630， P=0.003）. ConclusionImplementation of the MDT treatment regimen can significantly reduce the short-term risk of gastrointestinal bleeding in patients with cirrhotic portal hypertension， while its long-term benefits require further follow-up verification.

ObjectiveTo explore the mechanism and pathway of Gandou Fumu decoction （GDFMD） in the development of liver fibrosis in Wilson's disease （WD）. MethodFirst， 30 TX-j mice were randomly divided into the model group， high-dose， medium-dose， and low-dose GDFMD groups， and penicillamine group， with six mice in each group， and another six wild-type mice were used as the normal group. The high-dose， medium-dose， and low-dose GDFMD groups were intragastrically administered drugs of 13.92， 6.96， 3.48 g·kg^-1. In the penicillamine group， 0.1 g·kg^-1 of penicillamine was given by intragastric administration. The model group and the normal group were given equal volume of normal saline， once a day， for four consecutive weeks. Samples were collected four weeks after gavage， and enzyme-linked immunosorbent assay （ELISA） was used to detect type Ⅲ procollagen peptide （PCⅢ）， collagen type Ⅳ （Col Ⅳ）， hyaluronic acid （HA）， and laminin （LN）. Hematoxylin-eosin （HE）， Masson， and picric acid-Sirus red collagen （Sirus Red） staining were used to observe the histopathological changes of liver fibrosis. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）， immunohistochemistry， and Western blot were used to observe the expressions of α-smooth muscle actin （α-SMA） and collagen type Ⅰ （Col Ⅰ）， which were related to the activation of hepatic stellate cells （HSCs）. The expression of miR-29b-3p was observed by Real-time PCR. The expression of Unc-51-like kinase 1 （ULK1） and its downstream-related factors were observed by Western blot. The downstream genes of miR-29b-3p were verified by the dual luciferase reporter gene detection method. ResultCompared with the normal group， the four items of liver fibrosis （PCⅢ， Col Ⅳ， HA， and LN） in the model group were significantly abnormal （P<0.01）， and the pathology was significantly abnormal. The expression of HSC activation-related indicators including α-SMA and Col Ⅰ， as well as α-SMA mRNA and Col Ⅰ mRNA was up-regulated （P<0.05， P<0.01）， and miR-29b-3p expression was down-regulated （P<0.01）. ULK1， p-ULK1， autophagy-related gene 13 （Atg13）， p-Atg13， Beclin-1， FAK family kinase-interacting protein of 200 kDa （FIP200）， activating molecule in BECN1-regulated autophagy protein 1 （AMBKA1）， and microtubule-associated protein 1 light chain 3Ⅱ/Ⅰ（LC3Ⅱ/Ⅰ） were up-regulated （P<0.05， P<0.01）. p62 protein expression was down-regulated （P<0.01）. Compared with the model group， the four items of liver fibrosis in the high-dose， medium-dose， and low-dose GDFMD groups and the penicillamine group were significantly improve （P<0.01）， and the pathological conditions were improved. The expression of HSC activation-related indicators including α-SMA and Col Ⅰ， as well as α-SMA mRNA and Col Ⅰ mRNA was down-regulated （P<0.05， P<0.01）， and the expression of miR-29b-3p was up-regulated （P<0.01）. ULK1， p-ULK1， Atg13， p-Atg13， Beclin-1， FIP200， AMBKA1， and LC3Ⅱ/Ⅰ were down-regulated （P<0.05， P<0.01）， and p62 protein expression was up-regulated （P<0.01）. The prediction software predicted that there was a binding site between miR-29b-3p and ULK1. The dual-luciferase reporter gene detection method indicated that the luciferase activity of the ULK1-WT plasmid-transfected cell group was reduced when miR-29b-3p mimics were co-cultured （P<0.01）. ConclusionGDFMD can regulate ULK1-mediated autophagy by up-regulating miR-29b-3p and further exert its anti-hepatic fibrosis effect in Wilson's disease.

Wilson's disease （WD） is a copper metabolism disorder caused by mutations in the ATP7B gene， with diverse phenotypes and complex pathogenesis. It is one of the few rare diseases that can achieve good clinical efficacy through standardized treatment. Since there are few systematic reviews of this disease， we summarize the pathogenesis and treatment methods of WD from traditional Chinese and western medicine by reviewing the literature related to WD. In western medicine， ATP7B gene mutation is considered as the root cause of WD， which affects copper transport and causes copper metabolism disorders. The excessive copper deposited in the body will result in oxidative stress， defects in mitochondrial function， and cell death. Western medicine treatment of WD relies mainly on drugs， and copper antagonists are the first choice in clinical practice， which are often combined with hepatoprotective and antioxidant therapy. Surgery is a common therapy for the patients with end-stage WD， and gene therapy provides an option for WD patients. According to the traditional Chinese medicine （TCM） theory， WD is rooted in constitutional deficiency and copper accumulation and triggered by dampness-heat accumulation or phlegm combined with stasis. The patient syndrome varies in different stages of the disease， and thus the treatment should be based on syndrome differentiation. The TCM treatment method of nourishing the liver and kidneys and warming the spleen and kidneys can address the root cause. The methods of clearing heat and drying dampness， resolving phlegm and dispelling stasis， and soothing liver and regulating qi movement can be adopted to treat symptoms. On the basis of syndrome differentiation， special prescriptions for the treatment of WD have been formulated， such as Gandou decoction， Gandouling， and Gandou Fumu decoction， which have been widely used in clinical practice. TCM and western medicine have their own advantages and shortcomings. The integrated Chinese and western medicine complementing with each other demonstrates great therapeutic potential. This paper summarizes the pathogenesis and treatment of WD with integrated Chinese and western medicine， aiming to provide a reference for the clinical diagnosis and treatment of this disease.

Objective:To compare the impact of orthodontic treatment on pulp volume in adolescents and adults.Methods:Cone-beam CT data of 62 patients undergoing orthodontic treatment at the Department of Orthodontics, Stomatological Hospital of Chongqing Medical University, from January 2019 to March 2022 were collected. Patients were divided into two age groups (31 patients in each group): adolescent group (aged 13-17, 17 males and 14 females) and adult group (aged 21-25, 12 males and 19 females). Pre-and post-treatment reconstructions of the pulp and dental tissues of upper first molars (UM1) and lower central incisors (L1) were performed. Measurements included pulp volume for UM1 (UM1 P) and L1 (L1 P), pulp chamber volume (UM1 PC) and root canal volume (UM1 RC) for UM1, root length for L1 (L1 RL), and mesiobuccal root length for UM1 (UM1 RL), as well as chamber heights at specific landmarks [the lengths from the central fossa fusion site to the roof of the pulp chamber (H1), the floor of the pulp chamber (H2), the nearest point of root divergence as well as crown-root bifurcation (H3), the farthest point of root divergence (H4), and the pulp chamber height (H5)] in UM1. Changes in these indices were calculated and analyzed using paired and independent sample t-tests for within-group and between-group differences, respectively. Pearson correlation was used to assess potential associations among H5, root length, and pulp volume changes. Results:Before and after orthodontic treatment, no significant difference was observed in the adult group for L1 P ( t=-0.03, P=0.975), while significant differences were noted for UM1 P, UM1 PC, and UM1 RC ( t=9.98, P<0.001; t=9.04, P<0.001; t=6.69, P<0.001). In the adolescent group, significant differences were found for both L1 P and UM1 P ( t=2.25, P=0.029; t=6.30, P<0.001). After orthodontic treatment, the absolute value changes of UM1 P, UM1 PC, and L1 P in the adolescent group were (19.75±9.58), (15.07±7.65) and (1.89±6.29) mm 3, respectively, and in the adult group were (13.33±9.41), (9.16±7.05) and (0.02±4.66) mm 3, respectively ( t=3.77, P<0.001; t=4.48, P<0.001; t=2.34, P=0.048). There was no significant absolute difference in the amount of UM1 RC between the two groups after orthodontic treatment ( t=0.86, P=0.391). Before and after orthodontic treatment, the absolute value changes of L1 RL, H1 and H5 in the adolescent group were (0.54±0.41), (0.38±0.27) and (0.71±0.33) mm, respectively, and the absolute value changes in the adult group were (0.78±0.62), (0.26±0.20) and (0.57±0.28) mm, respectively ( t=-2.43, P=0.017; t=2.96, P=0.004; t=2.57, P=0.011). Whereas no significant differences were observed for UM1 RL, H2, H3, and H4 ( t=-0.85, P=0.400; t=0.43, P=0.669; t=-0.50, P=0.619; t=1.46, P=0.148). Additionally, significant correlations were found between changes in H5 and UM1 RL with UM1 P ( r=0.35, P<0.001; r=0.19, P=0.030), but not between Changes in L1 RL and L1 P ( r=0.11, P>0.05). Conclusions:The effect of orthodontic treatment on pulp volume in adolescents and adults were different.

Objective: To investigate the mechanism underlying the effects exerted by the Qizhu prescription (QZP) in breast cancer (BC), and the respective targets. Methods: Expression data from the ArrayExpress and The Cancer Genome Atlas (TCGA) were used to identify differentially expressed genes (DEGs) in BC. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were performed on the DEGs to identify genes involved in protein–protein interactions. Molecular docking was used to explore the dynamic relationship between active molecules and targets. Cell function experiments and animal studies were conducted to evaluate the effects of hub genes and active QZP compounds on BC cell behavior. Results: Among the 25 evaluated BC-related targets of QZP, matrix metalloproteinase-1 (MMP1) and epidermal growth factor receptor (EGFR) exhibited the highest degrees of dysregulation. GO and KEGG enrichment analyses revealed that the anti-BC targets of QZP primarily affected drug responses and pathways in cancer cells. Molecular docking analysis suggested potential interactions between EGFR and quercetin/luteolin, as well as between MMP1 and luteolin/kaempferol/quercetin. Quercetin significantly reduced BC cell proliferation, migration, invasion, and tumor development in vivo. Treatment of BC cells with quercetin decreased the expression or activation of several associated proteins. Conclusion The findings of our study provide new insights into the therapeutic potential of traditional Chinese medicine against BC, with particular reference to QZP.

In order to promote the development of hair transplantation, particularly the establishment of standards, the Hair Transplantation Expert Group of Plastic and Aesthetic National Medical Quality Control Center invited experts in the field of hair transplantation across China and formed a draft of the Expert Consensus on Standard Terminology for Hair Transplantation based on the collation of relevant literature and monographs. By combining Delphi methodology and consensus meetings, the expert group conducted several rounds of consultations on issues such as follicular unit anatomy, harvesting, dissection, and implantation, ultimately presenting 54 terminologies. This consensus considers the original Chinese and English meanings as well as the professional characteristics of terms used in hair transplantation, highlights the unique features and advantages of hair transplantation, and preserves its essence while promoting innovation, with the hope of providing valuable reference for clinical researchers engaged in hair transplantation both domestically and internationally, and better facilitating the standardization and advancement of the field.
