Metabolic-associated fatty liver disease (MAFLD) and osteoporosis (OP) are two very common metabolic diseases. A growing body of experimental evidence supports a pathophysiological link between MAFLD and OP. MAFLD is often associated with the development of OP. Rutaecarpine (RUT) is one of the main active components of Chinese medicine Euodiae Fructus. Our previous studies have demonstrated that RUT has lipid-lowering, anti-inflammatory and anti-atherosclerotic effects, and can improve the OP of rats. However, whether RUT can improve both fatty liver and OP symptoms of MAFLD mice at the same time remains to be investigated. In this study, we used C57BL/6 mice fed a high-fat diet (HFD) for 4 months to construct a MAFLD model, and gave the mice a low dose (5 mg·kg^-1) and a high dose (15 mg·kg^-1) of RUT by gavage for 4 weeks. The effects of RUT on liver steatosis and bone metabolism were then evaluated at the end of the experiment [this experiment was approved by the Experimental Animal Ethics Committee of Institute of Medicinal Biotechnology, Chinese Academy of Medical Sciences (approval number: IMB-20190124D₃03)]. The results showed that RUT treatment significantly reduced hepatic steatosis and lipid accumulation, and significantly reduced bone loss and promoted bone formation. In summary, this study shows that RUT has an effect of improving fatty liver and OP in MAFLD mice.

Objective: To identify the social ecological factors of individual, family, and physical environments for affecting the development of fundamental motor skills (FMS) among overweight and obese children, so as to provide a basis for the future intervention design and policy making. Methods: From March to April 2022, one public primary school was recruited from each of the 4 main urban areas in Shijiazhuang, and a total of 425 children in schools were recruited for data collection including individual, family, physical environmental factors, by using a stratified cluster random sampling approach. Test of Gross Motor Development-Third Edition (TGMD-3) was used to evaluate children s FMS. Hierarchical linear regression model was employed to analysis the associations between the 18 factors for individual, family, and physical environments, and the FMS of overweight and obese children. Results: Individual level including the child s age, gender and sleep duration, and family level including high family economic level, parental support for physical activity, and the physical activity environment surrounding the family and community were consistent predictors of movement skills ( B =0.422, -1.972, 0.014, 0.045, 1.042, 0.827, 1.898), ball skills ( B =0.858, 3.953, 0.013, 0.092, 2.141, 1.173, 1.954), and composite skills ( B =1.305, 1.915, 0.028, 0.142, 3.091, 1.962, 3.879) among overweight and obese children ( P <0.05). Furthermore, child s body mass index (BMI), moderate to vigorous physical activity, perceived motor competence, pleasure of exercise,as well as BMI and physical activity levels of their primary caregiver, were associated with different types of FMS ( P <0.05). Individual, family, and physical environmental factors had moderate to high predictive explanatory power for FMS among overweight and obese children ( 2=0.69, 0.75, 0.93, P <0.01). Conclusions The factors influencing the development of FMS in overweight and obese children are multifaceted, with individual, family, and physical environment factors all playing significant roles.Corresponding measures should be actively taken to improve FMS in overweight and obese children.

Objective To explore whether ferulic acid can inhibit the progression of T-cell acute lymphoblastic leukemia in vivo and in vitro by regulating PTEN/PI3K/AKT signaling pathway.Methods The T-cell acute lymphoblastic leukemia Jurkat cells were divided into the control group,the ferulic acid treatment group and the LY294002 treatment group for in vitro experiment.The cells in the control group were given normal culture;cells in the ferulic acid treatment group were given different concentrations(1.25,2.5,5,10,20,40,80,160 μmol/L)of ferulic acid,respectively,and the cell proliferation was detected by CCK-8 method,to screen the experimental concentration;cells in the LY294002 treatment group were given 50 μmol/L PI3K/AKT inhibitor LY294002.The cells proliferation,apoptosis and invasion were detected by clone formation assay,flow cytometry and Transwell assay.The relative expression levels of nuclear protein Ki67,proliferating cell nuclear antigen(PCNA),cleaved caspase-3,cleaved caspase-9,E-cadherin,N-cadherin,Vimentin,PTEN,p-PI3K,PI3K,p-AKT and AKT proteins were detected by Western blot.The nude mice models of transplanted tumors were constructed by 30 male BALB/c nude mice,and they were averagely divided into the normal group and the ferulic acid treatment group for in vivo experiment.The normal group was given normal saline by gavage,while the ferulic acid treatment group was given 75 mg/kg ferulic acid by gavage after inoculating Jurkat cells.The weight and volume changes of transplanted tumors were compared,and the levels of Ki67,cleaved caspase-3/caspase-3,E-cadherin,N-cadherin,PTEN,p-PI3K,PI3K,p-AKT and AKT in tumor tissues were detected.Results In vitro experiment,compared with the control group,the clone formation rate of cells,number of invasion cells,Ki67,PCNA,N-cadherin,Vimentin,p-PI3K/PI3K and p-AKT/AKT in the 5,10,20 μmol/L ferulic acid treatment group and the LY294002 treatment group were significantly decreased(P<0.05),while the apoptosis rate,cleaved caspase-3/caspase-3,cleaved caspase-9/caspase-9,E-cadherin and PTEN were significantly increased(P<0.05).In vivo experiment,compared with the normal group,the weight and volume of tumors were reduced in the ferulic acid treatment group,Ki67,N-cadherin,p-PI3K/PI3K and p-AKT/AKT in tumor tissues were significantly decreased,cleaved caspase-3/caspase-3,E-cadherin and PTEN were significantly increased,with statistically significant differences(P<0.05).Conclusion Ferulic acid can inhibit the proliferation and invasion of T-cell acute lymphoblastic leukemia Jurkat cells in vivo and in vitro,and induce apoptosis,its mechanism may be related to the regulation of PTEN/PI3K/AKT signaling pathway.

Background::Oral anti-coagulants (OAC) are the intervention for the prevention of stroke, which consistently improve clinical outcomes and survival among patients with atrial fibrillation (AF). The main purpose of this study is to identify problems in OAC utilization among hospitalized patients with AF in China.Methods::Using data from the Improving Care for Cardiovascular Disease in China-Atrial Fibrillation (CCC-AF) registry, guideline-recommended OAC use in eligible patients was assessed.Results::A total of 52,530 patients with non-valvular AF were enrolled from February 2015 to December 2019, of whom 38,203 were at a high risk of stroke, 9717 were at a moderate risk, and 4610 were at a low risk. On admission, only 20.0% (6075/30,420) of patients with a diagnosed AF and a high risk of stroke were taking OAC. The use of pre-hospital OAC on admission was associated with a lower risk of new-onset ischemic stroke/transient ischemic attack among the diagnosed AF population (adjusted odds ratio: 0.54, 95% confidence interval: 0.43–0.68; P <0.001). At discharge, the prescription rate of OAC was 45.2% (16,757/37,087) in eligible patients with high stroke risk and 60.7% (2778/4578) in eligible patients with low stroke risk. OAC utilization in patients with high stroke risk on admission or at discharge both increased largely over time (all P <0.001). Multivariate analysis showed that OAC utilization at discharge was positively associated with in-hospital rhythm control strategies, including catheter ablation (adjusted odds ratio [OR] 11.63, 95% confidence interval [CI] 10.04–13.47; P <0.001), electronic cardioversion (adjusted OR 2.41, 95% CI 1.65–3.51; P <0.001), and anti-arrhythmic drug use (adjusted OR 1.45, 95% CI 1.38–1.53; P <0.001). Conclusions::In hospitals participated in the CCC-AF project, >70% of AF patients were at a high risk of stroke. Although poor performance on guideline-recommended OAC use was found in this study, over time the CCC-AF project has made progress in stroke prevention in the Chinese AF population.Registration::ClinicalTrials.gov, NCT02309398.

Objective To explore the mechanism of the effect of itraconazole ethanolamine tablets on the CD40/CD40L axis in children with idiopathic thrombocytopenic purpura(ITP).Methods 80 children with ITP were selected as the study subjects.They were divided into a control group(n=40)and a study group(n=40)using a digital random table method.The control group was treated with cyclosporine,while the study group was treated with itraconazole ethanolamine tablets.Both groups were treated continuously for 3 months.Compare the clinical efficacy of two groups of patients T lymphocyte subpopulation levels[CD3+CD4+and CD4+/CD8+,as well as adverse reactions.Detect CD40 on the surface of lymphocyte membrane and platelet membrane in two groups of patients CD40L level,plasma sCD40 and sCD40L levels were detected using ELISA.Results The total effective rate of the study group(92.50%)was significantly higher than that of the control group(75.00%)(P<0.05).CD3+CD4+,CD4+/CD8+,The expression levels of sCD40 in plasma were higher than before treatment,CD8+and peripheral blood CD19+CD40+The expression levels of CD3+,CD40L+cells,and plasma sCD40L were lower than before treatment;Research group CD3+CD4+,CD4+/CD8+,The expression level of sCD40 in plasma was higher than that in the control group,CD8+,And peripheral blood CD19+CD40+The expression levels of CD3+CD40L+cells and plasma sCD40L were lower than those of the control group(P<0.05).The CD40L+cells on the surface of peripheral blood platelet membranes after two treatment groups were lower than before treatment;The CD40+on the surface of peripheral blood platelet membrane in the study group was higher than that in the control group,CD40L+cells were lower than those in the control group(P<0.05).The total adverse rate of the study group(15.00%)was lower than that of the control group(22.50%),but there was no significant difference between the two groups(P>0.05).Conclusion The treatment of ITP in children with eltrombopag olamine tablets has good clinical effi-cacy,regulates the level of T lymphocyte subsets,and is safe.

Objective:To evaluate the efficacy and safety of antaitasvir phosphate 100 mg or 200 mg combined with yiqibuvir for 12 weeks in patients with various genotypes of chronic hepatitis C, without cirrhosis or compensated stage cirrhosis.Methods:Patients with chronic hepatitis C (without cirrhosis or compensated stage cirrhosis) were randomly assigned to the antaitasvir phosphate 100 mg+yiqibuvir 600 mg group (100 mg group) or the antaitasvir phosphate 200 mg+yiqibuvir 600 mg group (200 mg group) in a 1∶1 ratio. The drugs were continuously administered once a day for 12 weeks and observed for 24 weeks after drug withdrawal. The drug safety profile was assessed concurrently with the observation of the sustained virological response (SVR12) in the two patient groups 12 weeks following the drug cessation. The intention-to-treat concept was used to define as closely as possible a full analysis set, including all randomized cases who received the experimental drug at least once. The safety set was collected from all subjects who received the experimental drug at least once (regardless of whether they participated in the randomization group) in this study. All efficacy endpoints and safety profile data were summarized using descriptive statistics. The primary efficacy endpoint was SVR12. The primary analysis was performed on a full analysis set. The frequency and proportion of cases were calculated in the experimental drug group (antaitasvir phosphate capsules combined with yiqibuvir tablets) that achieved "HCV RNA

Objective:To investigate the clinicopathological, molecular pathological features, and family genetic pedigree of small cell carcinoma of the ovary, hypercalcemic type (SCCOHT).Methods:A total of 16 cases of SCCOHT diagnosed in Obstetrics and Gynecology Hospital of Fudan University from January 2013 to January 2023 were collected. The clinicopathologic features, SMARCA4/2/B1 protein expression, outcomes and SMARCA4 gene detection were reported. A follow-up study was also carried out.Results:The average age at diagnosis was 28.7 years (range 17-38 years). The preoperative calcium level was evaluated in 3 of 6 patients. The tumor was unilateral in all 16 cases, ranged from 8 to 26 cm (average 15.8 cm) in the greatest dimension. Extraovarian spread was present in 7 cases. In 10 cases, the tumors were initially misinterpreted as other ovarian neoplasms. BRG1 and BRM expression by immunohistochemistry were all lost in detected cases, while INI1 exhibited retained nuclear expression. All BRM-negative SCCOHTs also lacked BRG1 protein,but retained INI1 expression. SCCOHTs were only focally positive for EMA, CKpan, Calretinin, SALL4, and diffusely positive for WT1. Two of nine cases exhibited mutation-type p53 immunoreactivity. Ki-67 index was 58% on an average. ER, PR, FOXL2, α-inhibin, chromogranin A and LCA were negative in all the cases. SMARCA4 sequencing was available in 8 cases of SCCOHT, which revealed a germline SMARCA4 mutation in one patient, and others carried somatic mutation. Furthermore, two daughters, mother and an aunt of a patient with germline mutation were reported to be SMARCA4 mutation carriers. Follow-up was available for 15 patients, and the 6-month, 1-year and 2-year survival rate was 65.8%, 45.1%, and 22.6%, respectively. For patients in FIGO stages Ⅱ+Ⅲ, 6-month, 1-year survival rate was 53.6% and 35.7% respectively, compared to 80% (6-month) and 60% (1-year) in patients of staged I ( P=0.358). Conclusions:With dismal prognosis of SCCOHT, accurate diagnosis is necessary. The typical age distribution, a panel of various staining results, especially concomitant loss of BRG1 and BRM may be of diagnostic aid and can be used to distinguish SCCOHT from its histological mimics. After the diagnosis of SCCOHT, genetic testing and genetic counseling are recommended.

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.
