Objective To summarize and discuss the clinical results of lumbar catheter drainage auxiliary ventricle drainage surgical puncture on patients with intraventricular hemorrhage about postoperative ADL.Methods The 86 patients with intraventricular hemorrhage admitted to our hospital were randomly divided into two groups,43 patients in control group were given conventional lateral ventricle puncture and continued external drainage,43 patients in observation group were given lumbar catheter drainage auxiliary ventricle drainage surgical puncture based on the conventional treatment.Clinical efficacy were observed,and functional outcomes were evaluated.Results The clearance rate of intraventricular hemorrhage and hospitalized days of the observation group were lower than those of the control group (t =4.23,11.82,all P ＜ 0.05),Quality of life in the observation group was better than that in the control group(x2 =1.73,P ＜ 0.05).Conclusion The clinical result of lumbar catheter drainage auxiliary ventricle drainage surgery for intraventricular hemorrhage in patients is satisfactory and worthy of clinical application.

Objective To clarify the effects of HBV co-infection on liver function of patients with different types of hepatic echinococcosis.Methods We recruited 409 patients diagnosed with hepatic echinococcosis at three hospitals in western regions in China from 2014 to 2015.Venous blood was withdrawn to detect to liver function indications.ELISA was performed to detect HBsAg.We analyzed liver function in patients stratified by different types of hepatic echinococcosis with or without HBV infection.Results The hepatic echinococcosis patients infected with HBV had more severe impairment in liver functions such as reduced albumin and increased transaminase.The patients with hepatic alveolar echinococcosis were more vulnerable to HBV infection compared with those with hepatic cystic echinococcosis (38.4％ vs.86.4％, P<0.05).In addition, liver injury was more severe in patients diagnosed with alveolar hepatic echinococcosis and HBV infection compared with those diagnosed with cystic hepatic echinococcosis and HBV infection (all P<0.05).Conclusion Hepatic alveolar echinococcosis patients co-infected with HBV have worse liver injury compared with those hepatic cystic with HBV. Therefore, they deserve special attention in clinical treatment.

Objective:To conduct theoretical analysis and experimental research on peripherally inserted venous catheters, establish theoretical models of interaction between different materials catheters and simulated skin tissues, and test different catheters at the same time to provide theoretical basis and experimental basis for the optimization design.Methods:According to the mechanical properties of the catheter at 25 ℃ and 37 ℃, a finite element model of the catheter and simulate skin tissue was established. The relationship between catheter folds and material and structure during puncture was analyzed, and the stiffness, radiographic properties, etc. were tested experimentally.Results:The performance of the catheter at different temperatures is closely related to its material. The wrinkle situation of the catheter is related to the catheter material and the inclination of the wedge surface. The elastic modulus of the polyurethane (PU) catheter is about 500 MPa and 250 MPa, respectively at room temperature (25 ℃) and body temperature (37 ℃), which meets the clinical needs of high rigidity during puncture and soft material during indwelling. When the catheter structure is the same, the PU catheter is less prone to wrinkles than the fluorinated ethylene propylene copolymer (FEP) catheter. When the catheter material is the same, the smaller the inclination of the wedge surface, the less likely the catheter to wrinkle.Conclusions:Appropriately reducing the inclination of the wedge-shaped surface of the needle of peripherally inserted venous catheters can improve the success rate of puncture. The PU catheters have good mechanical properties, they are not prone to wrinkles during puncture, and their stiffness can be reduced at body temperature, which can not only increase the success rate of puncture, but also reduce the occurrence of complications. Therefore, PU catheters have a better clinical application prospect.

It is necessary to explore potent therapeutic agents via regulating gut microbiota and metabolism to combat Parkinson's disease(PD).Dioscin,a bioactive steroidal saponin,shows various activities.How-ever,its effects and mechanisms against PD are limited.In this study,dioscin dramatically alleviated neuroinflammation and oxidative stress,and restored the disorders of mice induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine(MPTP).16 S rDNA sequencing assay demonstrated that dioscin reversed MPTP-induced gut dysbiosis to decrease Firmicutes-to-Bacteroidetes ratio and the abundances of Enterococcus,Streptococcus,Bacteroides and Lactobacillus genera,which further inhibited bile salt hy-drolase(BSH)activity and blocked bile acid(BA)deconjugation.Fecal microbiome transplantation test showed that the anti-PD effect of dioscin was gut microbiota-dependent.In addition,non-targeted fecal metabolomics assays revealed many differential metabolites in adjusting steroid biosynthesis and pri-mary bile acid biosynthesis.Moreover,targeted bile acid metabolomics assay indicated that dioscin increased the levels of ursodeoxycholic acid,tauroursodeoxycholic acid,taurodeoxycholic acid and β-muricholic acid in feces and serum.In addition,ursodeoxycholic acid administration markedly improved the protective effects of dioscin against PD in mice.Mechanistic test indicated that dioscin significantly up-regulated the levels of takeda G protein-coupled receptor 5(TGR5),glucagon-like peptide-1 receptor(GLP-1R),GLP-1,superoxide dismutase(SOD),and down-regulated NADPH oxidases 2(NOX2)and nu-clear factor-kappaB(NF-κB)levels.Our data indicated that dioscin ameliorated PD phenotype by restoring gut dysbiosis and regulating bile acid-mediated oxidative stress and neuroinflammation via targeting GLP-1 signal in MPTP-induced PD mice,suggesting that the compound should be considered as a prebiotic agent to treat PD in the future.

OBJECTIVES: To screen the risk factors for predicting venous thromboembolism (VTE) risk after hip fracture in the elderly, to establish a prediction model based on these factors, and to analyze its prediction efficacy. METHODS: A total of 52 hip fracture patients over 60 years old with VTE admitted to the Department of Orthopaedic Trauma, Xiangya Hospital, Central South University from March 2017 to April 2019 were selected as a thrombus group, and another 52 hip fracture patients over 60 years old without VTE were selected as a control group. The differences of hospitalization data and examination results between the 2 groups were compared. Logistic regression model was used to explore the influence of risk factors on VTE risk after hip fracture in the elderly and construct the prediction model based on these factors. The receiver operating characteristic curve was used to analyze the predictive effectiveness of model, Hosmer-lemeshow goodness of fit test was used to evaluate the fitting degree of prediction model. RESULTS: Univariate analysis showed that injury-admission interval, Caprini score, WBC count, platelet count, neutrophil count, neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, monocyte-to-lymphocyte ratio, systemic immune-inflammatory index (SII), and fibrinogen in the thrombus group were higher than those in the control group (all CONCLUSIONS SII, Caprini score, and injury-admission interval are independent predictors of VTE after hip fracture in the elderly. The prediction model based on these 3 factors has a good efficacy on the prediction of VTE risk, and could provide important reference for the prevention, management, and treatment of VTE after hip fracture in the elderly.
