In recent years， traditional Chinese medicine （TCM） has achieved significant progress in the treatment of inflammatory bowel disease （IBD）. A comprehensive literature search was conducted covering the period from January 1， 2010， to December 30， 2024， across Chinese databases including China National Knowledge Infrastructure （CNKI）， Wanfang Data， VIP China Science and Technology Journal Database， and the Chinese Biomedical Literature Service System， as well as international databases such as PubMed， Web of Science， and Embase. The clinical applications and mechanistic studies of TCM in IBD were systematically reviewed. The current status of TCM research on the etiology and pathogenesis of IBD， innovative clinical practices， and multimodal therapeutic approaches， including Chinese herbal formulas， single herbs or active compounds， acupuncture， herbal retention enema， and acupoint application， were summarized， together with their synergistic effects when combined with western medical treatments. The development and application of Chinese patent medicines for IBD are undergoing a profound transition from efficacy validation to mechanistic exploration. Mechanistic studies on the effects of TCM in IBD mainly focus on regulating gut microbiota homeostasis， repairing the intestinal mucosal barrier， and modulating intestinal immune balance. Furthermore， future research directions for TCM-based IBD management are proposed， including the establishment of TCM diagnostic and treatment models， expanding integrated applications of external and internal TCM therapies， innovating personalized treatment strategies， and advancing drug development. These efforts aim to provide insights for the standardized and precision-oriented development of TCM in the diagnosis and treatment of IBD.

Animal model research on spleen and stomach diseases in traditional Chinese medicine （TCM） is of great significance for elucidating the nature of diseases and syndromes and for revealing the mechanisms of action of Chinese herbal medicinals. At present， studies on classical TCM syndrome models of spleen and stomach diseases mainly focus on spleen deficiency syndrome， liver constraint syndrome， and damp-heat syndrome. Model construction is mostly based on the etiological and pathophysiological characteristics of syndrome， and model evaluation primarily involves macroscopic manifestations and physicochemical indicators. This paper summarizes the current research status of animal models integrating disease and syndrome for seven common spleen and stomach diseases， including chronic gastritis and gastric precancerous lesions， gastroesophageal reflux disease， functional dyspepsia， inflammatory bowel disease， irritable bowel syndrome， functional constipation， and functional diarrhea. The modeling methods and characteristics of disease-syndrome combined animal models for each disease are analyzed. It is proposed that future research on disease-syndrome integration in spleen and stomach diseases should move toward syste-matic， precise， and integrative development， and that interdisciplinary and cross-disciplinary research approaches should be adopted to enhance the predictive value and application efficiency of disease-syndrome combined animal models.

Aligning with the ulcerative colitis （UC） dynamic characteristics of latent pathogens， that is "remaining latent and concealed， and manifesting when triggered"， and following the latent pathogen theory， it is proposed that the core pathogenesis of UC recurrence is latent damp-heat pathogen concealed internally， progressing from qi to blood level over time， and leading to qi-blood disharmony and intestinal collateral damage. Accordingly， stage-based treatment is recommended. During the active stage， it is suggested to clear damp-heat， move qi， and regulate blood using modified Gegen Qinlian Decoction（葛根芩连汤）. During the remission stage， the treatment should focus on reinforcing healthy qi and venting pathogen， regulate and tonify the spleen and kidney with a self-made Jianpi Qingchang Mixture（健脾清肠合剂）. These approaches may provide a reference for the clinical treatment of UC.

ObjectiveTo explore the possible mechanism of Modified Gegen Qinlian Decoction （加味葛根芩连汤， MGQD） in the treatment of ulcerative colitis （UC） based on intestinal mucus barrier. MethodsThirty C57BL/6 mice were randomly divided into a control group， a model group and a MGQD group with 10 mice in each. Dextran Sulfate Sodium Salt （DSS） was used to construct the UC model in all groups except for the control group. Meanwhile， mice in the MGQD group were given 20 g/kg of MGQD decoction by gavage according to their body weight， while those in the control group and model group were given 0.2 ml/20 g of pure water by gavage， once a day for 7 consecutive days. On the day following the last gavage， the body weight， disease activity index （DAI） score， spleen weight， and colon length were compared. The pathological changes of the intestinal mucosal tissues were observed by HE staining； the protein expression levels of mucin 2 （MUC2） and leucine-rich repeat G protein-coupled receptor 5 （Lgr5） in the intestinal mucosal tissues were detected by immunofluorescence； the cuprocytes in the intestinal mucosal tissues were detected by AB/PAS staining； and the expression level of Ki67 in the intestinal mucosal tissues was detected by immunohistochemistry. ResultsHE staining showed that the colon mucosal tissue of the mice in the control group was intact. In the model group， the colon mucosal epithelial structure was severely damaged， with a large amount of inflammatory cell infiltration in the mucosal propria. In the MGQD group， the mucosal tissue structure was partially lost， with a small amount of inflammatory cell infiltration.The body weight and colon length of mice in the model group decreased significantly compared to those in the control group， while DAI scores and spleen weight increased， and the levels of MUC2， Ki67， Lgr5 proteins， and the number of goblet cells were significantly reduced （P＜0.01）. Compared to the model group， the MGQD group had increased body weight of mice， colon length， and decreased DAI scores and spleen weight； the levels of MUC2， Ki67， Lgr5 proteins， and the number of goblet cells were increased （P＜0.05 or P＜0.01）. ConclusionMGQD has a favorable ameliorative effect on UC-related symptoms and pathological tissue damage， and its mechanism of action may be related to the restoration of the prolife-ration and differentiation of intestinal stem cells into goblet cells， thereby promoting the repair of the intestinal mucus barrier.

Objective To investigate the characteristics of peripheral blood in the treatment of aplastic anemia(AA)with Bushen Shengxue Method and Yiqi Yangxue Method combined with Western medicine.Methods Totally 492 AA patients who were treated in 19 centers including Xiyuan Hospital China Academy of Chinese Medical Sciences from September 2018 to March 2021 were selected,and were randomized into three groups:161 cases in the Bushen Shengxue group,164 cases in the Yiqi Yangxue group,and 167 cases in the control group.All three groups were orally administered cyclosporine and androgens.Bushen Shengxue group was given Bushen Shengxue Granules,Yiqi Yangxue group was given Yiqi Yangxue Granules,and the control group was given placebo(half dosage of Bushen Shengxue granules).The general data,overall efficacy,and peripheral blood at the 1st month,the 4th month,and 6th month after treatment were analyzed.Results The total effective rate of Bushen Shengxue group was 98.8％(159/161),which was significantly higher than that of Yiqi Yangxue group(79.9％)and the control group(61.7％),with statistical significance(P＜0.001);The total effective rate of Yiqi Yangxue group was significantly higher than that of the control group(P＜0.001).Compared with before treatment,the hemoglobin(HGB)levels of all three groups of patients significantly increased after treatment(P＜0.001,P＜0.01),and the platelet levels of Bushen Shengxue group and the control group significantly increased after treatment(P＜0.001);after treatment,the HGB levels in the three groups were ranked from high to low as the Bushen Shengxue group,Yiqi Yangxue group and the control group(P＜0.01).25％of patients had HGB levels exceeding 20％of baseline values,Bushen Shengxue group took 1 month,while Yiqi Yangxue group and control group took 4 months;25％of patients had an increase in HGB levels exceeding 50％of the baseline value,Bushen Shengxue group took 6 months,while Yiqi Yangxue group and control group took more than 6 months.At 6 months,the number of patients with HGB elevation exceeding 20％and 50％of baseline values in Bushen Shengxue group was higher than that in Yiqi Yangxue group and the control group(P＜0.05,P＜0.001).25％of patients had white blood cell elevation exceeding 50％of the baseline value,Bushen Shengxue group took 4 months,Yiqi Yangxue group took 6 months,and the control group took more than 6 months.25％of patients showed an increase in platelet levels exceeding 100％of the baseline value,Bushen Shengxue group took 4 months,while Yiqi Yangxue group and control group took 6 months;at 6 months,the number of patients in Bushen Shengxue group and Yiqi Yangxue group with platelet elevation exceeding 20％of the baseline value was significantly higher than that in the control group(P＜0.01,P＜0.05).Conclusion Bushen Shengxue method combined with Western medicine intreating AA is better than the method of Yiqi Yangxue method combined with Western medicine.In terms of improving HGB,it is reflected in shortening the recovery time and increasing the number of beneficiaries,and the dosage can affect the recovery time and the number of beneficiaries at the same time;in terms of improving white blood cell and platelet,it is reflected in shortening the recovery time,and the dosage can affect the recovery time.

Objective:To evaluate the clinical efficacy of botulinum toxin type A (BTX-A) injection in enhancing chin aesthetics.Methods:A retrospective analysis was conducted on patients with suboptimal chin aesthetics who underwent dual-plane BTX-A injection at Plastic Surgery Hospital, Chinese Academy of Medical Sciences between August 2023 and March 2024. Prior to injection, patients were instructed to repeatedly pucker their lips forward and upward to identify the most prominent points of the mentalis muscle for injection. A 13 mm 30 G needle was inserted perpendicularly into the muscle layer, and BTX-A was administered at a concentration of 20 U/ml, with 3 U per injection point. For the patients exhibiting significant orange peel signs at rest, intradermal deep-layer BTX-A injection was concurrently performed at a concentration of 5 U/ml, with 0.5 U per linear track. Postoperative follow-up was conducted, and third-party physicians assessed pre- and post-treatment photographs using the global aesthetic improvement scale (GAIS) (scores ranging from 5 to 1, representing worse, no improvement, mild improvement, moderate improvement, and significant improvement, respectively). Patient satisfaction was also surveyed [categorized as very satisfied, satisfied, dissatisfied, or very dissatisfied; satisfaction rate = (very satisfied + satisfied) cases/total cases × 100%], along with their willingness to undergo repeated injections and recommend the procedure to others. Descriptive statistical analysis was performed using SPSS 24.0 software. Normally distributed continuous data were expressed as Mean±SD, and categorical data were expressed as counts (%).Results:A total of 120 patients were included, comprising 11 males and 109 females, aged 22-39 years (mean age of 33.3 years). Follow-up ranged from 1 to 5 months (mean of 1.3 months). Postoperatively, 102 patients reported subjective improvement in chin appearance, characterized by enhanced fullness and roundness of the chin. Thirty-one patients noted a slight elevation of the submental fat pad and improved definition of the cervicomental angle. The mean GAIS score was 1.61±0.78, with 76 cases scoring 1, 24 cases scoring 2, 10 cases scoring 3, and 10 cases scoring 4. Improvement (scores 1-3) was achieved in 91.7% (110/120) of patients. The subjective satisfaction rate was 85.0% (102/120), and 94 patients (78.3%) expressed willingness to undergo repeated injections and recommend the procedure to family or friends. Early postoperative complications included localized bruising in 17 cases, which was resolved within 10 d, and transient fine motor dysfunction of the lower jaw in 23 cases, with normal chewing, swallowing, and facial expressions, all of which were resolved completely within 6 weeks. No cases of mouth deviation, facial paralysis, allergic reactions, or other complications were observed.Conclusion:The application of BTX-A via intramuscular mentalis injection combined with intradermal deep-layer injection significantly improves both dynamic and static chin aesthetics. However, some common complications also ask for the further attention of practitioners.

Objective To evaluate the promoting effect of continuous low-intensity pulsed ultrasound(LIPUS)combined with microbubble(MB)cavitation therapy(hereinafter referred to as ultrasound cavitation therapy)on microcirculatory perfusion in the ischemic hindlimbs of mice,and to explore the non-invasive therapeutic potential of this treatment for limb arterial ischemic injury.Methods A mouse model of left hindlimb ischemia was established,and the mice were randomly assigned to 4 groups(16 mice per group)according to different treatment methods:model group,ultrasound contrast microbubble group(MB group),LIPUS treatment group(LIPUS group),and ultrasound cavitation therapy group(LIPUS+MB group).Mice in the model group were injected with 0.1 mL of normal saline via the tail vein,those in the MB group were injected with 0.1 mL of MB via the tail vein,those in the LIPUS group were treated with LIPUS on the ischemic hindlimb after injection of 0.1 mL of normal saline via the tail vein,and those in the LIPUS+MB group were treated with LIPUS on the ischemic hindlimb after injection of 0.1 mL of MB via the tail vein;each group was injected once a day for a total of 7 d.On the 1st,4th and 7th days after treatment,the microcirculatory perfusion in the ischemic hindlimbs of mice was evaluated using contrast-enhanced ultrasound.The effects of different treatments on promoting microcirculatory perfusion in the ischemic hindlimbs of mice were assessed by combining hematoxylin-eosin(H-E)staining and CD31 immunohistochemical staining of the gastrocnemius muscle tissue in the hindlimbs.Results The left hindlimb ischemia model was successfully constructed,and all model mice showed obvious ischemic microcirculation perfusion disorders with good model stability.After the 7th day of treatment,the LIPUS+MB group showed a increase in microcirculation perfusion in the ischemic hindlimb,with the ratio of microvascular flow on the ischemic to non-ischemic sides higher than that of the LIPUS group([94.33±4.51]%vs[70.33±2.09]%,P＜0.05).H-E staining results showed that the LIPUS+MB group had more newly formed capillaries and myofibroblasts in the gastrocnemius muscle,with better muscle structure repair compared to the LIPUS group,while the model group and MB group showed muscle cell necrosis,disorganized arrangement of muscle bundles,and sparse capillaries.CD31 immunohistochemical analysis further confirmed that ultrasonic cavitation therapy significantly outperformed traditional LIPUS treatment in promoting microcirculation perfusion,microvascular neogenesis,and tissue repair in ischemic skeletal muscles(CD31 relative expression level 5.03±0.33 vs 3.57±0.21,P＜0.01).Conclusion Compared with single LIPUS treatment,continuous ultrasound cavitation therapy has a more significant effect on promoting microcirculation perfusion in the ischemic hindlimb of mice,which provides a new strategy for microcirculatory perfusion disorders in skeletal muscles of limbs caused by peripheral arterial ischemic diseases.

Objective To investigate the fatigue and workload status among medical students,and to explore the latent profiles of fatigue and workload and their effects on sleep and emotion.Methods A cross-sectional study design with convenience sampling was employed to distribute a comprehensive survey via mixed online and offline modes,and medical college students were enrolled as the subjects for this investigation.The general demographic data,depression,anxiety and stress scale,Pittsburgh sleep quality index,Epworth sleepiness scale,insomnia severity index,National Aeronautics and Space Administration task load index(NASA-TLX)and fatigue scale-14(FS-14)were used to investigate the basic information of the medical students,their emotions(depression,anxiety and stress),sleep(sleep quality,sleepiness and insomnia),workload and fatigue status.Based on latent profile analysis,the types of workload-fatigue profiles and differences in sleep and emotion were analyzed.Results A total of 485 medical students were enrolled,with an average age of(22.07±2.42)years.The total score of the NASA-TLX was 64.44±12.50,and the total score of the FS-14 was 7.90±3.63.Latent profile analysis identified 3 distinct workload-fatigue profiles:low workload-medium fatigue group(12.8％),medium workload-low fatigue group(32.8％),and high workload-high fatigue group(54.4％).Among these,the medium workload-low fatigue group exhibited the highest performance level(all P＜0.05),while the low workload-medium fatigue group showed the lowest effort level and performance level(all P＜0.05).The high workload-high fatigue group showed the highest task-related demand and frustration level(all P＜0.05).Regarding sleep and emotional status,the medium workload-low fatigue group had significantly better outcomes compared to the high workload-high fatigue group and the low workload-medium fatigue group(all P＜0.05).Conclusion Medical students experience a heavy workload and subjective fatigue.It is essential to appropriately adjust their workload,prioritize sleep and emotional well-being,and alleviate fatigue levels,so as to sustain personal physical and mental health.
