Objective To investigate the regulatory mechanism of transforming growth factor-β1 (TGF-β1) in different types of mitral valvular disease (MVD) with atrial fibrillation (AF). Methods From August 2011 to August 2012, patients with moderate to severe MVD accompanied by AF who required mitral valve replacement at the Department of Cardiovascular Surgery, West China Hospital, Sichuan University, were included. Based on echocardiographic results, patients were divided into two groups: a mitral regurgitation (MR) with AF (MR-AF) group and a mitral stenosis (MS) with AF (MS-AF) group. Left atrial tissue samples were collected during surgery. Techniques such as enzyme-linked immunosorbent assay, real-time fluorescence quantitative polymerase chain reaction, immunohistochemistry, and Western blotting were used to detect key molecules in the TGF-β1/JNK pathway. Results Sixteen patients were enrolled. There were 8 patients in the MR-AF group, including 5 males and 3 females, with an average age of (41.38±11.19) years; and 8 patients in the MS-AF group, including 6 males and 2 females, with an average age of (43.12±5.30) years. The left atrial volume load was higher in MR-AF patients, while the left atrial pressure load was higher in MS-AF patients. In MS-AF patients, the relative expression levels of MAPK9, JUN, CASP3, BAX, and BCL2 mRNA in left atrial tissues were significantly upregulated. The serum TGF-β1 protein level and the relative expression levels of p-JNK, p-c-Jun, and Caspase-3 proteins in the left atrial tissues of the MR-AF group were higher. Myocardial cell damage was more severe in the MS-AF group, and the protein expression level of Bcl-2 was higher. Conclusion Different MVD have distinct hemodynamic characteristics. The myocardium of the left atrium in MR-AF patients is more prone to apoptosis, possibly through the activation of the TGF-β1/JNK signaling pathway.

Aim To compare the differences in the in vitro anti-precancerous lesions of gastric cancer(PL-GC)activities of different polar extracts from Bombyx batryticatus.Methods Bombyx batryticatus was ex-tracted by ethanol reflux,and the extract was further partitioned using different polarity organic solvents to obtain four fractions:petroleum ether(SYM),ethyl acetate(YSYZ),n-butanol(ZDC),and aqueous phase(SX).The PLGC cell model was established by inducing malignant transformation in GES-1 cells using N-methyl-N-nitro-N-nitrosoguanidine(MNNG).The optimal concentration of four extracts were determined by CCK-8 assay.The proliferation,migration and in-vasion of cells in each group were detected by plate cloning,scratch healing and Transwell assay,respec-tively.The expression levels of E-cadherin,Vimentin and key proteins of the PI3 K/AKT/mTOR signaling pathway in cells of each group were detected by West-ern blot.Meanwhile,chemical components of the four extracts were analyzed by UPLC-Q-TOF-MS/MS.Re-sults Compared with the normal group,the prolifera-tion,migration and invasion abilities of cells in the PL-GC group were significantly enhanced,the expression levels of E-cadherin proteins of PLGC cells were down-regulated,and the expression levels of Vimentin,p-PI3K,p-AKT and p-mTOR proteins of PLGC cells were up-regulated.Compared with the PLGC group,the four extracts attenuated the proliferation,migration and invasion abilities of PLGC cells,down-regulated the protein expression levels of Vimentin,p-PI3K,p-AKT and p-mTOR,and upregulated E-cadherin ex-pression in cells of the SYM,YSYZ,and ZDC groups.There was no statistical significance in the SX group.In addition,there were significant differences in the chemical components of the four different polar extracts of Bombyx batryticatus.The differential compounds were cysteine,histidine,etc.Conclusions The four different polar extracts of Bombyx batryticatus all can exert in vitro anti-PLGC effects by regulating the PI3K/AKT/mTOR signaling pathway to inhibit the EMT process.Among them,the extract of n-butanol had the strongest activity,followed by the extracts of ethyl ace-tate and petroleum ether.The aqueous phase had the weakest activity,and the difference in activity may be related to the different compounds such as Cysteine and Histidine.

Genistein is a naturally occurring compound widely found in leguminous plants and is the primary active ingredient in traditional Chinese medicinal herbs such as Astragalus,Puer-aria lobata(Kudzu),Fagopyrum esculentum(Buckwheat),and Rhodiola.Modern pharmacological research indicates that genistein possesses a variety of biological activities,including anti-inflammatory,antioxidant,antitumor,lipid-lowering,an-tidiabetic,anti-ultraviolet,and neuroprotective effects.There-fore,by summarizing and generalizing the pharmacological ac-tions and mechanisms of genistein,it is hoped to provide a basis for its clinical application and drug development.

Objective:To evaluate the intervention effects of different rehabilitation exercise training methods on adolescents with idiopathic scoliosis (AIS) through a network meta-analysis, providing a reference for exercise training interventions for AIS patients.Methods:A computer search was conducted in PubMed, Embase, Web of Science, EBSCO, Ovid, Cochrane Library, China Biology Medicine disc, China National Knowledge Infrastructure, VIP, and Wanfang Database, with the search period up to October 31, 2023. Two researchers independently screened the literature, extracted data, and assessed the risk of bias of the included studies according to preset criteria. A network meta-analysis was performed using RevMan and Stata software.Results:A total of nine randomized controlled trials were included. The network meta-analysis results of different rehabilitation exercise trainings on the Cobb angle in AIS patients showed that Schroth therapy [ SMD=0.50, 95% CI (0.11, 0.88), P<0.05] and Barcelona scoliosis physical therapy school (BSPTS) therapy [ SMD=0.78, 95% CI (0.18, 1.38), P<0.05] were more effective than routine nursing in reducing the Cobb angle. The effects of Schroth therapy [ SMD=-0.83, 95% CI (-1.50, -0.16), P<0.05] and BSPTS therapy [ SMD=-1.11, 95% CI (-2.09, -0.13), P<0.05] on Cobb angle were also better than core exercise therapy. Cumulative probability ranking indicated that BSPTS therapy was the best intervention. Regarding the impact on quality of life, network meta-analysis of different rehabilitation exercise trainings on the Scoliosis Research Society-22 questionnaire's four dimensions showed no significant differences in scores between groups ( P>0.05). Cumulative probability ranking indicated that core exercise therapy was the best intervention for physical function, mental health, and body pain, while BSPTS therapy was the best intervention for self-image perception. Conclusions:Based on current evidence, BSPTS therapy is the most effective in alleviating or reducing the Cobb angle in AIS patients. Core exercise therapy is the best for improving physical function, mental health, and alleviating body pain, while BSPTS therapy is the best for self-image perception in AIS patients.

Soy is a vital source of plant carbohydrates.However,it poses significant allergenic risks,particularly to young children and animals.Among the various proteins in soy,β-conglycinin,which con-stitutes approximately 30％of total soy carbohydrates,is a primary allergen.Undigested β-conglycinin can lead to intestinal damage by inhibiting cell growth,disrupting the cytoskeleton,and inducing apopto-sis.It can also enter the lymphatic and circulatory systems,triggering allergic reactions.Conventional ELISA methods for detecting β-conglycinin rely on polyclonal or monoclonal antibodies,which are limited by their large molecular weight,difficulty in accessing the protein core,and sensitivity to acidic and bas-ic conditions.To address these limitations,this study aimed to develop nanobodies(Nbs)against β-con-glycinin.Nbs,derived from the variable regions of heavy-chain antibodies found in camelids,have a mo-lecular weight approximately one-tenth that of conventional antibodies.They offer advantages such as small size,stable structure,high specificity,and strong affinity.A female alpacas was immunized five times using β-conglycinin,which showed a heavy chain antibody potency of 1∶16 000 by ELISA.Pe-ripheral blood lymphocytes were subsequently isolated and total RNA was extracted.The variable region of the heavy-chain antibody was amplified via PCR,and recombinant plasmids were constructed and transformed into the E.coli competency strain ER2738.The resulting library contained about 3.5×108 CFU/mL,which increased to 1.15×1012 PFU/mL after phage rescue,with a 100％Nbs gene insertion rate,indicating high diversity.Its Nbs phage output was significantly enriched by four rounds of solid-phase elution with an enrichment rate of 155.9.Four rounds of solid-phase panning yielded 35 positive clones,all of which shared the same amino acid sequence upon sequencing.The selected Nb was ex-pressed in a prokaryotic system,and its binding ability to β-conglycinin was confirmed using Western blotting and ELISA.The results demonstrated excellent specificity and affinity.This research lays the groundwork for developing a rapid and efficient detection method for β-conglycinin using Nbs,potentially enhancing food safety and allergen management.

Objective: To evaluate the efficacy and safety of plasma exchange (PE) in thymoma-associated myasthenia gravis (MG), thereby to provide theoretical support for its application in the treatment of thymoma-associated MG. Methods: A total of 133 patients with thymoma-associated MG admitted from January 2018 to September 2024 were retrospectively analyzed. Patients were matched using propensity score to reduce selection bias, yielding 22 matched pairs for both PE group (n=22) and non-PE group (n=22). Patient characteristics including gender, age of disease onset, course of disease, history of thymoma resection, clinical absolute scores [clinical absolute scores (CAS) and clinical relative scores (CRS)], and synchronized immunotherapy regimen of the two groups were analyzed. The CAS scores before and after treatment were compared between the two groups, and the CRS was used to assess the treatment efficiency. Safety of the two treatment regimens were also compared. Continuous variables were compared using the t-test or ANOVA, while categorical data were compared by the chi-square test. Results: A total of 133 patients were included and divided into two groups according to whether they underwent plasma exchange treatment: the PE group (n=22) and the non-PE group (n=111). To exclude bias caused by large difference in the number of cases between the two groups, we performed propensity score matching. After matching, the number of cases in both groups was 22. There was no significant difference in baseline clinical characteristics between the two groups (P>0.05), including gender, age of onset, duration of disease course, history of thymectomy and baseline CAS score before treatment. Compared to the non-PE group, patients in the PE group showed more significant improvement in CAS score (5.09±1.95 vs 3.59±1.50, P<0.05) and a higher CRS score (75.00% vs 50.00%, P<0.001). Compared to the non-PE group, PE group had significantly longer ICU stay, longer hospital stay and higher hospitalization cost (P<0.05). There was no statistically significant difference in adverse events between the two groups during treatment (P>0.05). During long-term follow-up, both the PE and non-PE groups showed relatively low 1-, 3-, and 5-year recurrence rate, with no significant difference between the two groups (P>0.05). Conclusion: This study indicates that plasma exchange has clear value in the treatment of patients with thymoma-associated myasthenia gravis. It can not only significantly improve patients' muscle strength to alleviate motor dysfunction and enhance quality of life, but also does not significantly increase the incidence of adverse reactions. Therefore, it can be regarded as one of the preferred treatment options that achieve a "balance between efficacy and safety" for such patients, and provides an important basis for optimizing treatment strategies, improving prognosis, and promoting the application of subsequent treatment regimens.

Type 2 diabetes mellitus (T2DM) is a highly prevalent chronic metabolic disease with an increasing incidence worldwide, that poses a significant risk to public health. In many current clinical practices for diabetes management, conventional Western treatments, including oral or injectable hypoglycemic agents, have serious side effects. Given that traditional Chinese medicine (TCM) is characterized by a multi-component, multi-target and multi-pathway approach, its combination with Western medicine could enhance efficacy and reduce adverse effects. Consequently, the use of TCM as a potential auxiliary or alternative treatment for the prevention and/or management of T2DM has emerged as a research hotspot. This article reviews existing reports on TCM in the treatment of T2DM and provides a detailed discussion of its applications. By integrating relevant clinical evidence, this review summarizes the clinical data on 23 TCM formulas and Chinese patent medicines, comprehensively describing their efficacy and potential pharmacological mechanisms in the treatment of T2DM. This includes an exploration of the impacts of TCM-based therapeutic interventions on T2DM-related microRNAs and their target genes. We hope this review not only offers new insights for future research directions but also enhances the understanding of the scientific value of TCM.
