Objective To investigate the effect of tetrandrine tablets on inflammatory cytokines and acute phase response following the first-dose of zoledronic acid in postmenopausal osteoporosis patients. Methods 80 postmenopausal osteoporosis patients receiving the first-dose of zoledronic acid admitted in the Affliated Xuzhou Municipal Hospital of Xuzhou Medical University from June, 2022 to December, 2024 were selected as study objects, and the patients were randomly divided into control group （40 cases, prophylactic treatment with acetaminophen tablets） and study group （40 cases, prophylactic treatment with tetrandrine tablets and acetaminophen tablets）. The high-sensitivity C-reactive protein （hs-CRP）, interleukin-1β （IL-1β）, IL-6, tumor necrosis factor-α （TNF-α） and the occurrence of acute phase reactions （fever, muscle and joint pain, gastrointestinal discomfort） between two groups were compared. Results The levels of serum hs-CRP, IL-1β, IL-6, and TNF-α in both groups significantly increased on day 1 and day 3 after infusion of zoledronic acid （all P values <0.05）. The levels of serum hs-CRP, IL-6, and TNF-α in the control group were higher than those in the study group on day 1 and 3 after infusion of zoledronic acid, with statistical significance （all P values <0.05）. In terms of acute phase reactions, the incidence of fever, muscle and joint pain in the control group after infusion of zoledronic acid were higher than those in the study group, with statistical significance （P<0.05）. No statistically significant difference in the incidence of gastrointestinal discomfort between the two groups （P>0.05）. Conclusion Tetrandrine tablets could reduce the expression levels of hs-CRP, IL-1β, IL-6, and TNF-α following the first-dose of zoledronic acid in postmenopausal osteoporosis patients, reduce the incidence of acute phase reactions, and alleviate adverse reactions.

Chronic ulcers on the body surface are non-healing wounds.Establishing a suitable animal model of chronic wounds will provide an important tool for research aimed at preventing and understanding the complexity of chronic wound formation and related pathological mechanisms in the human body.Animal wound models are usually constructed by inducing molecular abnormalities via external injury interventions to induce wound formation.Common modeling method include surgical resection,pressure ischemia,drugs,and radiation treatment.The success of model construction can then be evaluated by various monitoring method,such as natural recovery of the wound without intervention,measurement of wound size observation of physical signs,measurement of body mass,organ index,and infrared imaging.Despite the existence of numerous modeling and evaluating method,however,there is currently a lack of unified standards for animal chronic wound models.Researchers should thus choose appropriate modeling and model-evaluation method based on their actual needs,to obtain the best experimental result.

OBJECTIVE To explore the ameliorative effect of Tiaozhi Xiaoban Mixture on atherosclerosis and the potential role of long non-coding RNA(Linc RNA)in anti-atherosclerosis.METHODS A model of atherosclerosis was established in SD rats subjec-ted to a high-fat diet.At 4 weeks post-modeling,thoracic aortic tissues from atherosclerotic rats were collected for hematoxylin-eosin(HE)staining to systematically evaluate the anti-atherosclerotic effects of Tiaozhi Xiaoban Mixture at different doses.Biochemical kits were utilized to assess relevant indices related to blood lipid levels as well as liver and kidney function,thereby evaluating the impact of Tiaozhi Xiaoban Mixture on these parameters.Enzyme-linked immunosorbent assay(ELISA)was employed to measure serum inflam-mation markers influenced by Tiaozhi Xiaoban Mixture.Additionally,TUNEL staining and Western blot analysis were conducted to ex-amine the apoptotic effects of Tiaozhi Xiaoban Mixture on thoracic aorta tissue.Finally,qPCR was used to detect the expression levels of Line-HC,MALAT1,etc.,in order to evaluate how Tiaozhi Xiaoban Mixture affecting these specific RNA molecules.RESULTS Following treatment with Tiaozhi Xiaoban Mixture,the blood lipid profiles indicated that total cholesterol(TC),triglycerides(TG),and low-density lipoprotein cholesterol(LDL-C)were significantly down-regulated(P＜0.05,P＜0.01),while high-density lipopro-tein cholesterol(HDL-C)levels were up-regulated in the atherosclerotic rats.Moreover,serum levels of liver and kidney function markers such as aspartate aminotransferase(AST),alanine aminotransferase(ALT),blood urea nitrogen(BUN),and creatinine(Cr)exhibited down-regulation(P＜0.05,P＜0.01).Additionally,pro-inflammatory factors including interleukin-6(IL-6),interleukin-1 beta(IL-1β),tumor necrosis factor-alpha(TNF-α),high-sensitivity C-reactive protein(hs-CRP),and matrix metallopeptidase 9(MMP-9)were also reduced(P＜0.01),whereas the anti-inflammatory factor interleukin-10(IL-10)was found to be elevated(P＜0.01).Furthermore,after oral administration of Tiaozhi Xiaoban Mixture,expression levels of apoptosis-related factors NLRP3,ASC,Cleaved Caspase-1,Cleaved IL-1 β,Puma,Bax,Noxa,and MDM2 in thoracic aorta tissues from the atherosclerotic rats showed sig-nificant down-regulation(P＜0.05,P＜0.01).Notably,following treatment with Tiaozhi Xiaoban Mixture,mRNA levels of Linc-HC decreased while mRNA expression of MALAT1 increased(P＜0.05,P＜0.01).CONCLUSION Tiaozhi Xiaoban Mixture may inhibit the expression of Linc-HC and up-regulate the expression of MALAT1 to reduce the formation of atherosclerotic plaque,improve ab-normal blood lipids and liver and kidney function,alleviate inflammation and inhibit apoptosis.

There exist risks of ionizing radiation in radiodiagnosis examinations. Implementing shielding protection following the optimization and as low as reasonably achievable (ALARA) principles represents a measure to reduce radiation doses to patients. The implementation of shielding protection in clinical practices should meet high requirements due to variations in the modalities and items in radiodiagnosis examinations, the characteristics and irradiation method of X-ray beams, the method of automatic selection of image quality and radiation dose-related parameters by imaging equipment, the radiation sensitivity of human tissues and organs. This review introduced the shielding products, methods and effects in various radiodiagnosis examinations, as well as the current status and challenges in their applications, aiming to provide a reference for future related research and clinical practices.

Objective To summarize the changing prevalence of carbapenem resistance in Enterobacterales based on the data of CHINET Antimicrobial Resistance Surveillance Program from 2015 to 2021 for improving antimicrobial treatment in clinical practice.Methods Antimicrobial susceptibility testing was performed using a commercial automated susceptibility testing system according to the unified CHINET protocol.The results were interpreted according to the breakpoints of the Clinical & Laboratory Standards Institute(CLSI)M100 31st ed in 2021.Results Over the seven-year period(2015-2021),the overall prevalence of carbapenem-resistant Enterobacterales(CRE)was 9.43％(62 342/661 235).The prevalence of CRE strains in Klebsiella pneumoniae,Citrobacter freundii,and Enterobacter cloacae was 22.38％,9.73％,and 8.47％,respectively.The prevalence of CRE strains in Escherichia coli was 1.99％.A few CRE strains were also identified in Salmonella and Shigella.The CRE strains were mainly isolated from respiratory specimens(44.23±2.80)％,followed by blood(20.88±3.40)％and urine(18.40±3.45)％.Intensive care units(ICUs)were the major source of the CRE strains(27.43±5.20)％.CRE strains were resistant to all the β-lactam antibiotics tested and most non-β-lactam antimicrobial agents.The CRE strains were relatively susceptible to tigecycline and polymyxins with low resistance rates.Conclusions The prevalence of CRE strains was increasing from 2015 to 2021.CRE strains were highly resistant to most of the antibacterial drugs used in clinical practice.Clinicians should prescribe antimicrobial agents rationally.Hospitals should strengthen antibiotic stewardship in key clinical settings such as ICUs,and take effective infection control measures to curb CRE outbreak and epidemic in hospitals.
