BACKGROUND: Early control of low-density lipoprotein cholesterol (LDL-C) is crucial for reducing the progress of cardiovascular disease. However, its additional role to the risk of primary osteoporosis in men with coronary heart disease was inconclusive. Our study aims to determine the association of LDL-C and its trajectories for osteoporosis risk in the middle-aged and aged men of China. METHODS: The retrospective cohort study of 1546 men aged 69.74 ± 11.30 years conducted in Beijing, China from 2015 to 2022. And the incidence of primary osteoporosis was annually recorded. LDL-C trajectories were further identified by latent class growth model using repeated measurements of LDL-C. The association of baseline LDL-C for osteoporosis was estimated using hazard ratio (HR) with 95% CI in Cox proportional hazard model, while mean level and trajectories of LDL-C for osteoporosis were evaluated using odds ratio (OR) with 95% CI in logistic regression model. RESULTS: During the median 6.2-year follow-up period, 70 men developed primary osteoporosis. The higher level of baseline LDL-C (HR = 1.539, 95% CI: 1.012-2.342) and mean LDL-C (OR = 2.190, 95% CI: 1.443-3.324) were associated with higher risk of osteoporosis in men with coronary heart disease after adjusted for covariates. Compared with those in the LDL-C trajectory of low-stable decrease, participants with medium-fluctuant trajectory, whose longitudinal LDL-C started with a medium LDL-C level and appeared an increase and then decrease, were negatively associated with osteoporosis risk (OR = 2.451, 95% CI: 1.152-5.216). And participants with initially high LDL-C level and then a rapid decrease demonstrated a tendency towards reduced risk (OR = 0.718, 95% CI: 0.212-2.437). CONCLUSIONS Elevated LDL-C level and its long-term fluctuation may increase the risk of primary osteoporosis in men. Early controlling a stable level of LDL-C is also essential for bone health.

Drug repurposing offers a promising alternative to traditional drug development and significantly reduces costs and timelines by identifying new therapeutic uses for existing drugs. However, the current approaches often rely on limited data sources and simplistic hypotheses, which restrict their ability to capture the multi-faceted nature of biological systems. This study introduces adaptive multi-view learning (AMVL), a novel methodology that integrates chemical-induced transcriptional profiles (CTPs), knowledge graph (KG) embeddings, and large language model (LLM) representations, to enhance drug repurposing predictions. AMVL incorporates an innovative similarity matrix expansion strategy and leverages multi-view learning (MVL), matrix factorization, and ensemble optimization techniques to integrate heterogeneous multi-source data. Comprehensive evaluations on benchmark datasets (Fdataset, Cdataset, and Ydataset) and the large-scale iDrug dataset demonstrate that AMVL outperforms state-of-the-art (SOTA) methods, achieving superior accuracy in predicting drug-disease associations across multiple metrics. Literature-based validation further confirmed the model's predictive capabilities, with seven out of the top ten predictions corroborated by post-2011 evidence. To promote transparency and reproducibility, all data and codes used in this study were open-sourced, providing resources for processing CTPs, KG, and LLM-based similarity calculations, along with the complete AMVL algorithm and benchmarking procedures. By unifying diverse data modalities, AMVL offers a robust and scalable solution for accelerating drug discovery, fostering advancements in translational medicine and integrating multi-omics data. We aim to inspire further innovations in multi-source data integration and support the development of more precise and efficient strategies for advancing drug discovery and translational medicine.

AIM:To investigate the effect of Bushen formulae(BHF)on bone metabolism and its possible mechanism in ovariectomized rats with high salt intake.METHODS:According to the random number table method,80 SPF-grade Sprague-Dawley rats were divided into sham group,ovariectomy(OVX)group,medium-high-salt diet(MSD)group,high-salt diet(HSD)group,BHF group,BHF with normal saline(BHF+NS)group,BHF+MSD group,and BHF+ HSD group,with 10 rats in each group.After modeling,different diets and BHF formula interventions were administered,and the concentrations of sodium chloride added to MSD group and HSD group were 2%(w/w)and 8%(w/w),respective-ly.The dose of BHF was 7.8 g·kg-1·d-1,once a day,and the treatment lasted for 12 weeks.Bone density,bone microar-chitecture,bone parameters,bone metabolism biomarkers,bone histopathological changes,the expression of epithelial sodium channel α(ENaCα),Na-Cl cotransporter(NCC),and voltage-gated chloride channel 3(ClC-3)proteins in bone tissue were detected in each group.RESULTS:Compared with sham group,the rats in OVX group had reduced bone density and destroyed bone microstructure.Compared with OVX group,the bone microstructure in MSD and HSD groups was more significantly damaged,while the levels of bone formation markers,bone glycoprotein(BGP)and type Ⅰ procolla-gen N-terminal peptide(PINP),were significantly increased in HSD group(P<0.05).Moreover,the levels of bone re-sorption markers,such as amino-terminal cross-linked telopeptides of type Ⅰ collagen(NTX),carboxy-terminal cross-linked telopeptides of type Ⅰ collagen(CTX)and tartrate-resistant acid phosphatase(TRACP),were significantly in-creased(P<0.05),indicating that bone metabolism was in high-conversion state.High-salt diet accelerated the structural destruction of bone trabeculae,and Western blot results showed that high-salt diet caused decreases in the protein expres-sion levels of ENaCα and ClC-3 and an increase in the protein expression level of NCC in femoral tissues(P<0.05).After BHF intervention,the expression of relevant ion channels caused by high salt could be regulated to different degrees.CONCLUSION:Bushen formulae could differentially regulate the expression of relevant ion channels ENaCα,ClC-3,and NCC induced by high salt to different degrees,which has certain ameliorative and therapeutic effects on the imbalance of bone metabolism.

Objective To explore the efficacy and safety of recombinant human anti-severe acute respiratory syn-drome coronavirus 2(anti-SARS-CoV-2)monoclonal antibody injection(F61 injection)in the treatment of patients with coronavirus disease 2019(COVID-19)combined with renal damage.Methods Patients with COVID-19 and renal damage who visited the PLA General Hospital from January to February 2023 were selected.Subjects were randomly divided into two groups.Control group was treated with conventional anti-COVID-19 therapy,while trial group was treated with conventional anti-COVID-19 therapy combined with F61 injection.A 15-day follow-up was conducted after drug administration.Clinical symptoms,laboratory tests,electrocardiogram,and chest CT of pa-tients were performed to analyze the efficacy and safety of F61 injection.Results Twelve subjects(7 in trial group and 5 in control group)were included in study.Neither group had any clinical progression or death cases.The ave-rage time for negative conversion of nucleic acid of SARS-CoV-2 in control group and trial group were 3.2 days and 1.57 days(P=0.046),respectively.The scores of COVID-19 related target symptom in the trial group on the 3rd and 5th day after medication were both lower than those of the control group(both P＜0.05).According to the clinical staging and World Health Organization 10-point graded disease progression scale,both groups of subjects improved but didn't show statistical differences(P＞0.05).For safety,trial group didn't present any infusion-re-lated adverse event.Subjects in both groups demonstrated varying degrees of elevated blood glucose,elevated urine glucose,elevated urobilinogen,positive urine casts,and cardiac arrhythmia,but the differences were not statistica-lly significant(all P＞0.05).Conclusion F61 injection has initially demonstrated safety and clinical benefit in trea-ting patients with COVID-19 combined with renal damage.As the domestically produced drug,it has good clinical accessibility and may provide more options for clinical practice.

Objective To investigate the relationship and potential pathways between metal(loid)exposure and the risk of polycystic ovary syndrome(PCOS)in women of childbearing age. Methods This case-control study included 200 patients with PCOS(cases)and 896 non-PCOS controls with the age of 25-37 years.The concentrations of 29 metal(loid)s in the follicular fluid(FF)and clinical indicators in the serum were measured in all participants.Logistic regression analysis and mediation analysis were conducted to evaluate the associations between metal(loid)exposure and PCOS risk and investigate the possible roles of clinical indicators,respectively. Results Logistic regression analysis revealed an association between high copper levels in FF and increased PCOS risk(highest vs.lowest quartile:adjusted odds ratio=2.94,95%confidence interval:1.83-4.72).A high luteinizing hormone/follicle-stimulating hormone ratio and elevated levels of testosterone and anti-Müllerian hormone(AMH)were strongly associated with increased PCOS risk induced by high copper exposure.The mediation analysis indicated a mediating effect of AMH in the association between copper exposure and PCOS risk. Conclusion Copper may affect PCOS risk through the hypothalamic-pituitary-ovarian axis,mediated by AMH.Copper exposure and internal AMH levels are important indicators for early warning of PCOS development.

Objective To investigate the associations between preconception dietary patterns(DPs)among Chinese women of childbearing age and neonatal birth weight.Methods The subjects selected for the questionnaire survey and follow-up were women of childbearing age who underwent prenatal eugenic examination at Jiang'an Maternal and Child Health Hospi-tal.Dietary intake information was collected using a semi-quantitative food frequency questionnaire,dietary patterns were extrac-ted by principal component analysis,and the relationship between DPs and birth weight was analyzed by modified Poisson re-gression or linear regression models.Results The final analysis of 221 maternal and infant pairs showed that women who fol-lowed the"nuts-poultry"pattern,one of the four dietary patterns,had a lower risk of delivering large for gestational age(LGA)infants(RR:0.25;95％CI:0.08-0.79),which was more pronounced in those who delivered male infants(RR:0.14;95％CI:0.03-0.72).Conclusion The risk of having LGA newborn is decreased in woman who takes a preconception dietary pattern characterized by nuts and poultry,which is more pronounced in those delivering male infants.Females of childbearing age should maintain good dietary habits before conception to ensure proper growth and development of the fetus and reduce the risk of ad-verse birth outcomes.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective: This study compared the outcomes of laparotomic radical hysterectomy (LRH) and minimally invasive radical hysterectomy (MISRH) in patients with early-stage cervical cancer. Methods: The clinical data of patients with early-stage cervical cancer who underwent LRH or MISRH (laparoscopic/robotic) at Chang Gung Memorial Hospital, Linkou Branch, from 2002 to 2017 were retrospectively reviewed. The surgical safety (operation time, blood loss, blood transfusion rate, length of postoperative stay, and perioperative complications), overall survival (OS), disease-free survival (DFS), and recurrence pattern were analyzed. Propensity score matching (PSM) at a 3:1 ratio was performed to balance prognostic variables. Results: Of the 760 patients (entire cohort), 614 underwent LRH and 146 underwent MISRH.After PSM, 394 and 140 patients were included in the LRH and MISRH groups, respectively.The 5-year OS rate was significantly lower in the MISRH group than in the LRH group (85.6% vs. 93.2%, p=0.043), and the 5-year DFS rate (p=0.21) did not differ significantly. After PSM, the 5-year OS rates did not differ significantly between the MISRH and LRH groups (87.1% vs. 92.1%, p=0.393). The MISRH group had a significantly shorter operation time (p<0.001), lower intraoperative blood loss (p<0.001), lower blood transfusion rate (p<0.001), and shorter postoperative stay (p<0.001) but a significantly higher rate of intraoperative bladder injury (p<0.001) than the LRH group. Conclusion After PSM, MISRH is associated with nonsignificantly lower OS but a significantly higher risk of intraoperative urological complications than LRH.
