Osteoporosis is a common bone disease， whose incidence is still on the rise， posing great challenges to patients and society. This review mainly studies the pathogenesis of osteoporosis from the aspects of oxidative stress， inflammatory response， and glucolipotoxicity-induced injury and clarifies the efficacy and mechanism of some active ingredients of traditional Chinese medicine against osteoporosis through the integration of in vitro and in vivo experiments. The experimental results suggest that some active ingredients can improve bone resorption markers and maintain bone homeostasis by modulating inflammation， oxidative stress， etc. These active ingredients regulate osteoporosis through the receptor activator of nuclear transcription factor-κB （NF-κB） ligand （RANKL） pathway， osteoprotegerin （OPG） pathway， Wnt/β-catenin pathway， NF-κB pathway， mitogen-activated protein kinase （MAPK） pathway， adenosine monophosphate （AMP）-activated protein kinase （AMPK）/mammalian target of rapamycin （mTOR） pathway， and oxidative stress pathway. This review provides ideas for the progress of the prevention and treatment of osteoporosis with the active ingredients of traditional Chinese medicine， aiming to provide new potential lead compounds and reference for the development of innovative drugs and clinical therapy for the treatment of osteoporosis.

Objective:To analyze and predict the biological properties and function of Treponema pallidum OmpH protein by bioinformatics methods, purify the target protein, and prepare polyclonal antibodies. Methods:From January 2024 to February 2025, the research team from the Department of Clinical Laboratory at The First Affiliated Hospital of Hunan Traditional Chinese Medical College (Hunan Province Directly Affiliated Traditional Chinese Medical Hospital) conducted a study employing integrative approaches combining bioinformatics analysis with animal experimentation. During this investigation, the coding sequence of the T. pallidum outer membrane protein H (TpOmpH) was systematically retrieved from the National Center for Biotechnology Information (NCBI) database. And the bioinformatics tools, such as Protparam, Protscale,SignalP 6.0,NetNGlyc-1.0,TMHMM2.0,NetPhos-3.1,SOPMA,AlphaFold3,IEDB,STRING,C-immsim were used to analyze and predict the biological and immunological characteristics of TpOmpH protein. The full length of TpOmpH gene was synthesized and was cloned into the pET28a to construct the recombinant plasmid pET28a-TpOmpH. The the expression of target protein was induced by IPTG and was purified using affinity chromatography. The TpOmpH protein was used to immunize mice and the anti-serum was harvested, then the titer of antibody was detected. Results:TpOmpH is a hydrophobic outer membrane protein with a molecular weight of 19.7 kDa and strong stability. The TpOmpH protein is located outside the cell membrane and contains 11 serine, 4 threonine, and 1 tyrosine phosphorylation site, but no glycosylation sites. The 77.91% of the amino acids in TpOmpH protein are alpha helix, 8.72% are extended strand, 10.47% are random coils, and 2.91% are beta turns. The tertiary structure predicted by AlphaFold3 is in its optimal state. The TpOmpH protein has 4 CTL epitopes, 4 linear epitopes, and 5 spatial epitopes. The TpOmpH protein can interact with Tp92,MutS,SurA,TPANIC_0600 and other proteins which may be involved in Tp invasion. TpOmpH protein can induce an increase in B cell count, antibody content, Th cell count, NK cell count, as well as the expression of various cytokines. High purity TpOmpH protein was obtained through Ni 2+ affinity chromatography, which is consistent with the theoretical molecular weight. TpOmpH protein can induce mice to secrete polyclonal antibodies with antibody titers higher than 1∶10 000. Conclusion:TpOmpH protein is a hydrophobic protein located on the outer membrane of Tp, can induce mice to secrete high titer antibodies, which providing experimental basis for the pathogenesis of Tp and vaccine development.

This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations. Observationally, a history of gallstones without cholecystectomy was associated with a high risk of stomach cancer (adjusted odds ratio (aOR)=2.54, 95% confidence interval (CI) 1.50-4.28), liver and bile duct cancer (aOR=2.46, 95% CI 1.17-5.16), kidney cancer (aOR=2.04, 95% CI 1.05-3.94), and bladder cancer (aOR=2.23, 95% CI 1.01-5.13) in the general population, as well as cervical cancer (aOR=1.69, 95% CI 1.12-2.56) in women. Moreover, cholecystectomy was associated with high odds of stomach cancer (aOR=2.41, 95% CI 1.29-4.49), colorectal cancer (aOR=1.83, 95% CI 1.18-2.85), and cancer of liver and bile duct (aOR=2.58, 95% CI 1.11-6.02). MR analysis only supported the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer. This study added evidence to the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer, highlighting the importance of cancer screening in individuals with gallstones.

Portal vein thrombosis(PVT)is a common and severe complication in patients with liver cirrhosis,and alterations in portal hemodynamics are closely associated with the development of PVT.The presence of large spontaneous splenorenal shunt(SSRS)may lead to reductions in portal vein perfusion and blood flow velocity,which may compromise the anticoagulant effect on PVT.This article reports the treatment strategies of SSRS embolization combined with anticoagulant therapy that help to achieve complete recanalization of the portal vein;however,high-quality clinical studies are still needed to further validate and support the effectiveness of this strategy.

Objective:To investigate the protective effect of PSD95 on neurobehavioral abnormalities and synaptic damage in cortex induced by hypoxia exposure in mice.Methods:The 3-week-old C57BL/6 male mice were injected with neuron-specific adeno-associated virus through stereotaxic brain after 7 days of normal environment adaptation.The mice were divided into normoxia group(AAV-NC-Nor),control hypoxia group(AAV-NC-Hyp),normal oxygen group with over-expression of postsynaptic density-95(PSD95)(AAV-PSD95-Nor),and hypoxia group with over-expression of PSD95(AAV-PSD95-Hyp).Using a hypobaric hypoxia chamber,PSD95-overexpressing mice were continuously ex-posed to hypoxic conditions for 14 days to establish a hypoxia exposure model.The open field,elevated cross maze and conditioned fear tests were used to detect the neurobehavioral activities of mice,and Golgi staining was used to observe the density of neuronal dendritic spines in cortex.The expression of PSD95,SYN1 and N-methyl-D-aspartate receptor subtype 2A(NMDAR2A)were detected by Western blot.Result:Compared with the normal oxygen group,the total distance and average speed of exercise in the open field experiment of mice in hypoxia group increased(P＜0.01),the rigidity time of mice in the conditioned fear box decreased(P＜0.01),and the density of dendritic spines in cortical region decreased(P＜0.05).The expressions of PSD95,SYN1 and NMDAR2A were decreased(P＜0.05).After the over-expression of PSD95,the autonomic activity of mice was reduced,the fear memory was relieved(P＜0.05),the dendrite density was reversed(P＜0.05),and the expression of synaptic related protein was increased(P＜0.05).Conclusion:Over-expression of PSD95 can alleviate neurobehavioral abnormalities and decline of fear memory induced under hypoxia exposure,protect neuronal dendritic spine injury in cortical region,and up-regulate the expression of syn-aptic protein.
