Liver failure （LF） is a severe clinical syndrome characterized by severe impairment or decompensation of liver function. At present， the key role of immune molecules in the pathogenesis of LF has been well established. These molecules not only directly participate in the pathological process of LF， but also influence the course of LF by modulating the behavior of immune cells. In addition， immune molecules can be used as potential biomarkers for evaluating the prognosis of LF. This article summarizes the role of immune molecules in LF and explores the therapeutic strategies based on these immune molecules， in order to provide new directions for the diagnosis and treatment of LF.

Objective To investigate the role of Sneathia sanguinegens(S.sanguinegens)in the development of unexplained recurrent spontaneous abortion(URSA).Methods A case-control study was conducted to analyze the vaginal flora characteristics of 65 patients with URSA and 18 healthy controls through 16S rRNA gene sequencing.Toxicity profile of S.sanguinegens on human cervical cancer cells(ME-180),human umbilical vein endothelial cells(HUVEC)and human placental choriocarcinoma cells(JEG-3)was analyzed at the cellular level to assess the mechanism of it in adverse pregnancy outcomes.And S.sanguinegens was used to infect C57BL/6J mice to explore the toxic effect on living organisms.Results The relative abundance of Sneathia was increased in patients with URSA compared with healthy controls.It was positively correlated with the number of miscarriages,and was attributed to S.sanguinegens.We also found that S.sanguinegens damaged ME-180,JEG-3 and HUVEC cells.The degree of cellular damage was related to the level of S.sanguinegens added.Intravenous infection with S.sanguinegens caused inflammatory damage in several organs and extramedullary hematopoiesis in the spleen.Conclusion S.sanguinegens is closely related to URSA and should be emphasized in patients with high vaginal bacterial load.

The interleukin-10 （IL-10） family is expressed in various types of cells and has a wide range of biological functions， and it plays an important role in the development and progression of hepatic fibrosis. Hepatic fibrosis is a chronic liver disease characterized by abnormal repair of hepatic tissues after injury， activation of hepatic stellate cells， and excessive accumulation of extracellular matrix. The IL-10 family members include IL-10， IL-19， IL-20， IL-22， IL-24， IL-26， IL-28， IL-29， and IL-35， with similarities in structure and function， and changes in their expression levels are closely associated with the progression of hepatic fibrosis. Moderate upregulation of the expression of IL-10 family members can help maintain the quiescent state of hepatic stellate cells， promote the transformation of macrophages to anti-inflammatory phenotype， and regulate the activity of natural killer cells， thereby inhibiting inflammatory response， regulating cell apoptosis and autophagy， and finally reversing the progression of hepatic fibrosis. This article discusses the mechanism of action of IL-10 family members and their application in traditional Chinese medicine and Western medicine therapies， in order to provide new thoughts for the treatment of hepatic fibrosis.

Objective:The aim of this study is to investigate the main active substances of Qilin pills by high performance liq-uid chromatogre-electrostatic field orbitrap mass spectrometry(HPLC-Q-Orbitrap/MS),and explore the mechanism of its action in the treatment of asthenozoospermia by combining network pharmacology and molecular docking.Methods:(1)Qilin pills were quantita-tively and qualitatively analyzed by HPLC-Q-Orbitrap/MS.(2)The top 100 compounds in Qilin pills were screened by content analy-sis and SwissADME,and their targets were predicted.The asthenozoospermia targets were searched through the database.And a"pro-tein-protein interaction"(PPI)network was constructed.KEGG and GO analysis was performed using the DAVID database.And a"drug-target-pathway"network was constructed.(3)SailVina was used for molecular docking.Results:(1)A total of 1 275 known components were found and ranked in Qilin pills by HPLC-Q-Orbitrap/MS analysis.(2)The top 100 compounds in Qilin pills predicted a total of 1 053 targets and 184 potential therapeutic targets for asthenozoospermia.KEGG pathway analysis and GO analysis showed that the treatment of asthenozoospermia by Qilin pills may be related to the steroid hormone synthesis pathway,the response to steroid hormones,the chromosomal region of cells and the activity of steroid hydroxylase.The mechanism of Qilin pills in treating as-thenozoospermia may be related to regulating the synthesis,metabolism and reaction process of sex hormone in the body.(3)The mo-lecular docking results of its key targets(CYP19A1,ESR1,HSP90AA1,p53,HIF1α and BCL2)showed that the key active ingredi-ents M030,M039,M043,M050,M055 and M073 of Qilin pills had spontaneous binding.It had a binding energy of less than-5 kJ/mol.Conclusion:The material basis of Qilin pills has been explored by this study.And the mechanism of action of Qilin pills in the treatment of asthenozoospermia is highly bound to the expression and response process of steroid hormones,which provides a theoretical basis for the clinical application of Qilin pills.

OBJECTIVE: This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study. METHODS: A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants. RESULTS: Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m ²) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m ²) and obesity (≥ 28.0 kg/m ²) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m ² ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses. CONCLUSION This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

Objective:To construct the inflammation score(IS)and nutrition-immunity score(NIS)for patients with multiple myeloma(MM),and to verify their prognostic stratification effects and significance.Methods:The clinical data of 129 newly diagnosed MM patients admitted to our hospital from August 2011 to September 2022 were retrospectively analyzed.Univariate and multivariate Cox regression analysis of overall survival(OS)were comducted on clinical parameters,including inflammatory indicators such as red blood cell volume distribution width(RDW)and platelet count(PLT),nutritional-immune indicators such as albumin(ALB),absolute lymphocyte count(ALC),and suppressed immunoglobulin count(S-Ig count).To construct IS and NIS for prognosis,X-tile software and multivariate Cox regression analysis were used to verify the prognostic stratification role and significance of IS and NIS.The time-dependent receiver operating characteristic(ROC)curve,C-index curve,calibration curve,and decision curve analysis(DCA)were used to evaluate the discrimination,accuracy,and clinical net benefit of IS and NIS in predicting overall survival(OS),and compared to the international staging system(ISS).Results:IS was constructed based on the scores of RDW and PLT,and NIS was constructed based on the scores of ALB,ALC,and S-Ig count.According to X-tile analysis and multivariate Cox regression analysis,IS and NIS can divide the patients into three risk strata respectively:low,medium and high IS and NIS groups.The differences in OS and hazard ratio(HR)between the low,medium,and high strata were statistically significant(P＜0.05).IS and NIS are both independent prognostic predictors for MM.The area under the ROC curve(AUC)and C index of IS and NIS for predicting 1-to 7-year OS were greater than those of ISS,and both were greater than 0.7.The prediction results of IS and NIS for 1-,3-,and 5-year OS rates were well consistent with the actual observed results.The DC A curves of IS and NIS for predicting 1-,3-,and 5-year OS were higher than that of ISS in a wide range of threshold probability intervals.Conclusion:IS and NIS have independent predictive significance for OS in MM patients.Their predictive discrimination,accuracy,and clinical net benefit are higher and better than ISS,and they may have potential application value in MM prognosis.

Objective:To analyze the significance of total vitamin D(tVD),total procollagen type Ⅰ amino-terminal propeptide(tPINP)and β-CrossLaps(β-CTx)in the staging and prognosis of patients with multiple myeloma(MM).Methods:A total of 54 patients with newly diagnosed MM admitted to the Second Affiliated Hospital of Fujian Medical University from 2020 to 2022 were selected as the observation group(MM group),and 50 healthy persons who underwent physical examinations in our hospital were selected as the control group.The expression levels of tVD,tPINP and β-CTx in the two groups were detected by chemiluminescence method.The differences in the expression levels of tVD,tPINP and β-CTx among MM patients at different ISS stages were analyzed.The expression levels of tVD,tPINP and β-CTx in MM patients with different levels of hemoglobin(Hb),serum calcium(Ca),creatinine(Crea),albumin(ALB),β2-microglobulin(β2-MG)and lactate dehydrogenase(LDH)were compared.The correlations between the expression levels of tVD,tPINP,β-CTx and the aforementioned clinical parameters were analyzed,respectively.The relationship between the expression levels of tVD,tPINP,β-CTx and the progression-free survival(PFS)of MM patients was analyzed.Results:The expression level of tVD in the MM group was significantly lower than that in the control group(21.73±14.45 ng/ml vs 30.78±9.94 ng/ml,P=0.022).The expression level of β-CTx in the MM group was significantly higher than that in the control group(1.43±0.99 ng/ml vs 0.53±0.29 ng/ml,P=0.013).The tVD level in MM patients with ISS stage Ⅰ-Ⅱ was significantly higher than that of MM patients with ISS stage Ⅲ(29.50±14.59 ng/ml vs 12.62±7.73 ng/ml,P=0.028),indicating that the higher the ISS stage,the lower the tVD level.The tPINP andβ-CTx levels in MM patients with high Ca levels(＞2.65 mmol/L)were significantly higher than those in patients with low Ca levels(≤ 2.65 mmol/L)(P=0.016,P=0.021).The tVD level of MM patients was positively correlated with the ALB level(r=0.570),tPINP was positively correlated with Ca and β2-MG levels(r=0.791,r=0.673),and β-CTx was positively correlated with tPINP level(r=0.616).The PFS of the low tVD expression group was significantly lower than that of the high tVD expression group(P=0.041).Conclusion:The expression level of tVD is decreased in MM patients,which can be used as an indicator to evaluate the disease stage and prognosis of the patients.The β-CTx expression level is increased in MM patients.tPINP and β-CTx may be correlated with clinical symptoms such as osteolytic lesions and renal function changes in MM patients.

Objectives: This study aimed to present the Asia-Pacific consensus on long-term and sequential therapy for osteoporosis, offering evidence-based recommendations for the effective management of this chronic condition.The primary focus is on achieving optimal fracture prevention through a comprehensive, individualized approach. Methods: A panel of experts convened to develop consensus statements by synthesizing the current literature and leveraging clinical expertise. The review encompassed long-term anti-osteoporosis medication goals, first-line treatments for individuals at very high fracture risk, and the strategic integration of anabolic and anti resorptive agents in sequential therapy approaches. Results: The panelists reached a consensus on 12 statements. Key recommendations included advocating for anabolic agents as the first-line treatment for individuals at very high fracture risk and transitioning to anti resorptive agents following the completion of anabolic therapy. Anabolic therapy remains an option for in dividuals experiencing new fractures or persistent high fracture risk despite antiresorptive treatment. In cases of inadequate response, the consensus recommended considering a switch to more potent medications. The consensus also addressed the management of medication-related complications, proposing alternatives instead of discontinuation of treatment. Conclusions This consensus provides a comprehensive, cost-effective strategy for fracture prevention with an emphasis on shared decision-making and the incorporation of country-specific case management systems, such as fracture liaison services. It serves as a valuable guide for healthcare professionals in the Asia-Pacific region, contributing to the ongoing evolution of osteoporosis management.
