Chronic heart failure （CHF） is a complex clinical syndrome that the cardiac output is not enough to meet the metabolic needs of the body， or depends on the increase of filling pressure to compensate. Its high morbidity and mortality pose a serious threat to human health， necessitating attention and active intervention. At present， western medicine treatment of CHF is mainly based on diuretics， intravenous vasodilators， intravenous positive inotropic drugs， etc.， which， however， have problems such as long medication cycles， serious side effects， and limited applicable population. Recent studies have shown that traditional Chinese medicine can act in a multi-pathway， multi-component， and multi-target manner， showing unique advantages in the prevention and treatment of CHF. Buyang Huanwutang has the effects of tonifying Qi， activating blood， and dredging collaterals. Clinical and mechanism studies have confirmed that this prescription is effective in treating CHF and its syndromes. The clinical studies can be classified into two categories. Studies of the first category use simple modern medical diagnostic criteria as the inclusion criteria for CHF patients， which can improve the scientificity and objectivity. Studies of the second category uses modern medicine combined with traditional Chinese medicine disease diagnostic criteria for the screening of CHF patients， which helps to improve the accuracy of efficacy evaluation. However， there are problems such as the lack of unified research standards and the insufficiency of mechanism research. In addition， the available studies remain to be classified or summarized. This study systematically sorted out the clinical and mechanism studies of Buyang Huanwutang in the treatment of CHF in recent years to review the research status. In clinical treatment， Buyang Huanwutang can be used alone， or modified， or combined with other prescriptions or Western medicine. The mechanism studies predict that Buyang Huanwutang can ameliorate CHF by regulating the calcium balance， protecting the mitochondrial structure and function， and regulating intestinal flora. This review aims to provide a theoretical basis and practical guidance for the clinical application and optimization and subsequent in-depth study of Buyang Huanwutang in the treatment of CHF.

Ovarian cancer is the most lethal malignancy affecting the female reproductive system. Pharmacological inhibitors targeting CDK4/6 have demonstrated promising efficacy across various cancer types. However, their clinical benefits in ovarian cancer patients fall short of expectations, with only a subset of patients experiencing these advantageous effects. This study aims to provide further clinical and biological evidence for antineoplastic effects of a CDK4/6 inhibitor (TQB4616) in ovarian cancer and explore underlying mechanisms involved. Patient-derived ovarian cancer organoid models were established to evaluate the effectiveness of TQB3616. Potential key genes related to TQB3616 sensitivity were identified through RNA-seq analysis, and TRIM4 was selected as a candidate gene for further investigation. Subsequently, co-immunoprecipitation and GST pull-down assays confirmed that TRIM4 binds to hnRNPDL and promotes its ubiquitination through RING and B-box domains. RIP assay demonstrated that hnRNPDL binded to CDKN2C isoform 2 and suppressed its expression by alternative splicing. Finally, in vivo studies confirmed that the addition of siTRIM4 significantly improved the effectiveness of TQB3616. Overall, our findings suggest that TRIM4 modulates ubiquitin-mediated degradation of hnRNPDL and weakens sensitivity to CDK4/6 inhibitors in ovarian cancer treatment. TRIM4 may serve as a valuable biomarker for predicting sensitivity to CDK4/6 inhibitors in ovarian cancer.

Traditional Chinese medicine (TCM) is an ancient medical system distinctive and effective in treating cancer, depression, coronavirus disease 2019 (COVID-19), and other diseases. However, the relatively abstract diagnostic methods of TCM lack objective measurement, and the complex mechanisms of action are difficult to comprehend, which hinders the application and internationalization of TCM. Recently, while breakthroughs have been made in utilizing methods such as network pharmacology and virtual screening for TCM research, the rise of machine learning (ML) has significantly enhanced their integration with TCM. This article introduces representative methodological cases in quality control, mechanism research, diagnosis, and treatment processes of TCM, revealing the potential applications of ML technology in TCM. Furthermore, the challenges faced by ML in TCM applications are summarized, and future directions are discussed.

Objective:To assess the effectiveness of a 6-month Ba Duan Jin exercise program in improving the balance of community-dwelling older adults.Methods:A two arms, parallel-group, cluster randomized controlled trial was conducted in 1 028 community residents aged 60-80 years in 40 communities in 5 provinces of China. Participants in the intervention group (20 communities, 523 people) received Ba Duan Jin exercise 5 days/week, 1 hour/day for 6 months, and three times of falls prevention health education, and the control group (20 communities, 505 people) received falls prevention health education same as the intervention group. The Berg balance scale (BBS) score was the leading outcome indicator, and the secondary outcome indicators included the length of time of standing on one foot (with eyes open and closed), standing in a tandem stance (with eyes open and closed), the closed circle test, and the timed up to test.Results:A total of 1 028 participants were included in the final analysis, including 731 women (71.11%) and 297 men (28.89%), and the age was (69.87±5.67) years. After the 3-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 3.05 (95% CI: 2.23-3.88) points ( P<0.001). After the 6-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 4.70 (95% CI: 4.03-5.37) points ( P<0.001). Ba Duan Jin showed significant improvement ( P<0.05) in all secondary outcomes after 6 months of exercise in the intervention group compared with the control group. Conclusions:This study showed that Ba Duan Jin exercise can improve balance in community-dwelling older adults aged 60-80. The longer the exercise time, the better the improvement.

BACKGROUND:In the research on acupuncture treatment for lumbar disc herniation,most acupuncture treatments are performed under CT guidance or without guidance.The precise control of the target site and the effective acupuncture location are not clear. OBJECTIVE:To observe the clinical effects of acupuncture at Jiaji points under ultrasonic guidance in treating lumbar disc herniation. METHODS:A total of 70 cases of lumbar disc herniation,36 males and 34 females aged 18-65 years old,were selected from Chinese PLA General Hospital and Third Affiliated Hospital of Beijing University of Chinese Medicine.They were divided into trial group and control group by random number table method,with 35 cases in each group.The control group received acupuncture at Jiaji points.The trial group received acupuncture at Jiaji points under ultrasonic guidance.The patients were treated once on the day of treatment and 4,7 days after treatment.Visual analog scale score,Oswestry disability index,Japanese Orthopaedic Association score,and MOS 36-Item Short-Form Health Survey(SF-36)were evaluated before and after treatment. RESULTS AND CONCLUSION:(1)Compared with before treatment,the visual analog scale scores of both groups were decreased after treatment(P<0.01).Compared with the control group,the visual analog scale scores of the trial group were decreased on days 2,3,6,7 of treatment and 1,2 weeks after the end of treatment(P<0.05,P<0.01).(2)Compared with before treatment,Oswestry disability index after treatment was decreased in both groups(P<0.01).Compared with the control group,Oswestry disability index of the trial group was decreased from days 1 to 7 of treatment and 1,2 weeks after treatment(P<0.01).(3)Compared with before treatment,the Japanese Orthopaedic Association scores of both groups were increased after treatment(P<0.01).Compared with the control group,the Japanese Orthopaedic Association scores of the trial group were increased on days 3,7 of treatment and 1,2 weeks after treatment(P<0.05,P<0.01).(4)Compared with before treatment,SF-36 scores in both groups were increased after treatment(P<0.01).There was no significant difference in SF-36 scores between the two groups after treatment(P>0.05).(5)These results show that acupuncture at Jiaji points has curative effect on lumbar disc herniation,and ultrasonic guidance could improve the clinical curative effect of acupuncture at Jiaji points for lumbar disc herniation.

Objective To investigate the effect of Zuogui Jiangtang Jieyu Formula(左归降糖解郁方,ZJJF)on hippocampal neuron apoptosis in diabetic rats with depression and to ascertain whether its mechanism involves the regulation of JNK signaling pathway. Methods(i)A total of 72 specific pathogen-free(SPF)grade male Sprague Dawley(SD)rats were randomly divided into six groups,with 12 rats in each group:control,model,metformin(Met,0.18 g/kg)+fluoxetine(Flu,1.8 mg/kg),and the high-,medium-,and low-ZJJF dosages(ZJJF-H,20.52 g/kg;ZJJF-M,10.26 g/kg;ZJJF-L,5.13 g/kg)groups.All groups except control group were injected once via the tail vein with streptozotocin(STZ,38 mg/kg)combined with 28 d of chronic unpredictable mild stress(CUMS)to establish diabetic rat models with de-pression.During the CUMS modeling period,treatments were administered via gavage,with control and model groups receiving an equivalent volume of distilled water for 28 d.The effi-cacy of ZJJF in reducing blood sugar and alleviating depression was evaluated by measuring fasting blood glucose,insulin,and glycated hemoglobin levels,along with behavioral assess-ments,including the open field test(OFT),forced swim test(FST),and sucrose preference test(SPT).Hippocampal tissue damage and neuronal apoptosis were evaluated using hema-toxylin-eosin(HE)staining and terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling(TUNEL)staining.Apoptosis-related proteins Bax,Bcl-2,caspase-3,and the ex-pression levels of JNK/Elk-1/c-fos signaling pathway were detected using Western blot and real-time quantitative polymerase chain reaction(RT-qPCR).(ii)To further elucidate the role of JNK signaling pathway in hippocampal neuronal apoptosis and the pharmacological ef-fects of ZJJF,an additional 50 SPF grade male SD rats were randomly divided into five groups,with 10 rats in each group:control,model,SP600125(SP6,a JNK antagonist,10 mg/kg),ZJJF(20.52 g/kg),and ZJJF(20.52 g/kg)+Anisomycin(Aniso,a JNK agonist,15 mg/kg)groups.Ex-cept for control group,all groups were established as diabetic rat models with depression,and treatments were administered via gavage for ZJJF and intraperitoneal injection for SP6 and Aniso for 28 d during the CUMS modeling period.Behavioral changes in rats were evaluated through the OFT,FST,and SPT,and hippocampal neuron damage and apoptosis were ob-served using HE staining,Nissl staining,TUNEL staining,and transmission electron mi-croscopy(TEM).Changes in apoptosis-related proteins and JNK signaling pathway in the hippocampal tissues of rats were also analyzed. Results(i)ZJJF significantly reduced the high blood glucose,insulin,and glycated he-moglobin levels in model rats(P<0.01).It increased autonomous activity and decreased de-spair-like behaviors(P<0.01),improved the pathological damage of hippocampal neurons,increased the number of neuronal nuclei(P<0.01),and reduced the number of mechanocytes,vacuolar cells,and apoptotic neurons(P<0.05,P<0.01,and P<0.01,respec-tively).ZJJF down-regulated the expression levels of pro-apoptotic proteins Bax and caspase-3(P<0.01),up-regulated the anti-apoptotic protein Bcl-2(P<0.01),and significantly inhibit-ed the overexpression of phosphorylated JNK(p-JNK),Elk-1,and c-fos(P<0.01).(ii)SP6 in-creased autonomous activity and reduced despair time in model rats(P<0.05),although it had no significant effects on sucrose preference(P>0.05).It increased the number of Nissl bodies in hippocampal neurons(P<0.01),reduced the protein expression levels of Bax(P<0.01)and caspase-3(P<0.05),and decreased the number of apoptotic neurons(P<0.05).SP6 also increased the expression level of Bcl-2(P<0.01),and inhibited the high expression levels of p-JNK,Elk-1,and c-fos(P<0.01,P<0.01,and P<0.05,respectively),suggesting that hip-pocampal neuronal apoptosis in diabetic rats with depression is associated with abnormal ac-tivation of JNK signaling pathway.Compared with ZJJF group,ZJJF+Aniso group showed a decrease in sucrose preference(P<0.05)and an increase in despair time(P<0.01)with more notable hippocampal neuronal damage.This group also exhibited a decrease in expression level(P<0.01)Bcl-2 and an increase in expression levels of Bax,caspase-3,p-JNK,Elk-1,and c-fos(P<0.01,P<0.05,P<0.05,P<0.01,and P<0.05,respectively),indicating that the antidepressant effects of ZJJF,its improvement of neuronal apoptosis,and regulation of JNK signaling molecules could all be reversed by a specific JNK agonist. Conclusion ZJJF exerts a significant hypoglycemic effect and ameliorates the apoptosis of hippocampal neurons by inhibiting the activation of JNK signaling pathway,which is a promising formula for the treatment of diabetic depression in clinical settings.

Myocardial fibrosis （MF） is a prevalent pathological process in a spectrum of cardiac conditions， including myocardial infarction， hypertensive heart disease， and dilated cardiomyopathy. It is marked by an overabundance of extracellular matrix deposition， diminished myocardial compliance， and impaired cardiac function， which can lead to arrhythmias and sudden cardiac death. The current therapeutic approach primarily aims to suppress the progression of fibrosis， yet the therapeutic outcomes are poor. The pathogenesis of MF involves multiple signaling pathways， including the transforming growth factor-beta （TGF-β）/Smads signaling pathway， nuclear factor-kappa B （NF-κB） signaling pathway， phosphoinositide 3-kinase （PI3K）/protein kinase B （Akt） signaling pathway， and mitogen-activated protein kinase （MAPK） signaling pathway. Traditional Chinese medicine （TCM） boasts a rich history in the treatment of cardiovascular diseases， offering distinctive benefits such as minimal side effects and high safety， and it has demonstrated promising therapeutic effects in the treatment of MF. In recent years， research has turned its attention to the application of TCM in modulating the signaling pathways associated with MF. It has been demonstrated that TCM can modulate the MF-related signaling pathways to exert anti-inflammatory effects， regulate cellular autophagy， cell proliferation， and apoptosis， reduce myocardial oxidative stress and damage， and inhibit the activation of fibroblasts and collagen synthesis， thereby exhibiting the potential to mitigate or even reverse the progression of MF. Experimental research and clinical observations indicate that TCM formulas such as Yixin Futing decoction， Luhong prescription， Zhilong Huoxue Tongyu capsules， and Kangjian Yixin prescription can effectively ameliorate MF and enhance cardiac function through the multi-component regulation of multiple cellular pathways. Specific TCM constituents， including isoliquiritigenin and astragaloside， have been shown to inhibit the expression of TGF-β₁， thereby disrupting the Smad signaling pathway. Compounds like glycyrrhizic acid and allicin can suppress the NF-κB signaling pathway and curtail collagen synthesis in myocardial cells， and forsythoside can activate the PI3K/Akt signaling pathway， contributing to its anti-fibrotic effects.

Objective To investigate the relationship between serum L-carnitine and its related metabolites[trimethylamine(TMA)and trimethylamine N-oxide(TMAO)]levels and gestational diabetes mellitus(GDM)in the second trimester of pregnant women in Shanghai.Methods A case-control study was conducted in 280 pregnant women between 18 and 23 weeks of gestation from January 2018 to January 2021.Among them,134 cases of GDM were the case group(GDM),and 146 cases with normal blood glucose(BG)were the control group(Con).Serum L-carnitine,TMA and TMAO levels were quantified by ultra high performance liquid chromatography-mass spectrometry.Logistic regression analysis,stratified analysis and linear regression were used to explore the relationship between L-carnitine,TMA and TMAO levels and GDM and glucolipid metabolism.Results Serum L-carnitinelevelwas significantly lower in GDM group than that in Con group(P<0.01).After adjusting for confounders,logistic regression showed a 70%reduction in the risk of GDM in the group with highest tertile of L-carnitine compared with the group with lowest tertile(OR 0.30,95%CI 0.15～0.63).The risk of GDM decreased by 14%for each 1 μmol/L increase in serum L-carnitine(OR 0.86,95%CI 0.80～0.93).Serum L-carnitine was negatively correlated with 1 hPG(r=-0.21,P<0.01)and 2 hPG(r=-0.15,P<0.05),respectively,TMA was negatively correlated with 2 hPG(r=-0.21,P<0.01).Conclusions Higher serum L-carnitine level may be negatively associated with GDM.Serum L-carnitine and TMA levels were negatively correlated with blood glucose levels.

Inflammatory response is one of the key mechanisms of cerebral ischemia/reperfusion injury(CIRI),which seriously affects the prognosis of patients.In recent years,it has been found that long non-coding RNA(LncRNA)is closely related to the inflammatory response of cerebral ischemia/reperfusion injury,and can affect the development and prognosis of CIRI through multiple pathways.The article reviews and summarizes the LncRNAs and their action pathways affecting the inflammatory response in CIRI.The article preliminary explores the possible mechanisms by which LncRNAs affect CIRI,and also briefly summarizes the drugs related to LncRNA therapy.In order to provide new therapeutic targets and research ideas for the treatment of CIRI.

From January 1, 2013, to March 1, 2024, nine patients with hematological malignancies complicated by Gilbert’s syndrome in Peking University People’s Hospital underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT). The patients comprised seven male and two female cases, with a median age of 38 (13-60) years old. Among them, three cases were acute myeloid leukemia, three cases were acute lymphocytic leukemia, two cases were myelodysplastic syndrome, and one case was chronic myelomonocytic leukemia. None of the patients had viral hepatitis. Of the nine cases, seven cases received the Bu-Cy+ATG regimen, while the other two cases received the TBI-Cy+ATG regimen (Bu, busulfan; Cy, cyclophosphamide; ATG, antithymocyte immunoglobulin; and TBI, total body irradiation). All patients achieved neutrophil engraftment, and eight received platelet engraftment. The median total bilirubin level was 45.4 (22.5-71.2) μmol/L before transplantation and 22.0 (18.0-37.2) μmol/L on -1d of preconditioning. The total bilirubin level on +20d after the transplantation of eight patients decreased compared with the baseline level before transplantation. Moreover, one patient had a transient increase in the total bilirubin level on +5d after transplantation, which was considered to be attributed to the toxicity of Bu. No patients were complicated by hepatic veno-occlusive disease. The median follow-up time was 739 (42-2 491) days. During the follow-up period, one patient died of recurrence, and the remaining eight patients had disease-free survival events.
