Objective To investigate the effect of postoperative complications to the aged after total hip replacement.Methods According to hospitalization order,120 patients undergoing total hip replacement operation were assigned into the intervention group and the control group with 60 patients in each group.In the intervention group,the patients received comprehensive intervention of diet nursing,psychological nursing,complication prevention and rehabilitation exercise.The control group received usual care.Then duration of hospital stay,incidence of complication,psychological state and compliance with functional exercises were compared between two groups.Results In the intervention group,the hospitalization time was shorter,the incidence rate of complication was lower,and psychological state and compliance with functional exercises were better than the control group.Conclusions The comprehensive intervention can reduce the incidence rate of complication,shorten hospitalization time,raise quality of care and facilitate recovery of patients.

Objective:To investigate the clinical efficacy of levodopa combined comprehensive therapy on the children with ametropic amblyopia.Methods:One hundred three patients (180 eyes) with ametropic amblyopia admitted into our hospital from April 2013 to March 2016 were randomly divided into the control group and the study group.Fifty-two patients (90 eyes) in the control group were treated with comprehensive therapy,and fifty-one patients (90 eyes) in study group were treated with levodopa combined comprehensive therapy.After six months of treatment,the treatment efficacy,pattern visual evoked potential (P-VEP),visual sensitivity,and visual function of patients were observed and compared between the two groups,and the adverse reaction were recorded and compared.Results:At six months after treatment,the effective rate of study group was 90.00％,which was significantly higher than that of control group (68.89％,P＜0.05).The wave amplitude ofP-VEP Pl00 of both groups showed a remarkable increase,which was much higher in the study group (P＜0.05);the incubation period in both groups were obviously decreased,while they were markedly lower in the study group (P＜0.05).The visual acuity under 100％,25％,10％ and 5％ of spatial frequency were conspicuously higher than those of control group (P＜0.05).And correction convergence range,and correction separation range in study group were much higher than those of control group,and corrected near stereo vision was markedly lower than that of control group (P＜0.05).Additionally,no significant difference was found in the incidence of adverse reactions between the two groups (P＞0.05).Conclusion:Levodopa combined comprehensive therapy had a good ability of improving function of visual central neurons,visual acuity and binocular stereo vision functions.

Objective To study the effect of ursolic acid (UA) intervention on hepatocyte apoptosis induced by TGF-β1 and its potential mechanism.Methods Primary hepatocytes were extracted from healthy SD rats by in situ perfusion,cultured for 12-24h,then randomly divided into the following groups:blank control group,UA control group (UA 25μmol/L),TGF-β1 group (TGF-β1 2.5ng/ml),UA intervention group (UA 25μmol/L and TGF-β1 2.5ng/ml),DPI intervention group (DPI 0.5μmol/L and TGF-β1 2.5ng/ml).Each group was treated with drugs for corresponding time and their proliferation and apoptosis were detected by flow cytometry,the expression of CD95 (Fas) mRNA was analyzed by RT-qPCR,the expression of protein CD95 and membrane translocation of NADPH oxidase (NOX) subunit p47Phox were analyzed by Western blotting,and the reactive oxygen species (ROS) generation in primary hepatocytes was analyzed with reactive oxygen detection kit.Results UA intervention at 30min before TGF-β1 stimulating hepatocytes markedly reduced hepatocyte apoptosis (63.97 ± 3.19 vs 80.53 ± 1.56,P＜0.01) and promoted hepatocyte proliferation (18.67 ± 1.60 vs 10.83 ± 2.03,P＜0.01).UA intervention notably down-regulated the expressions of CD95 mRNA and protein (1.28 ± 0.15 vs 2.40 ± 0.25,P＜0.01;1.05 ± 0.15 vs 1.37 ± 0.18,P＜0.05),restrained membrane translocation of p47phox (1.13 ± 0.12 vs 1.76 ± 0.22,P＜0.01),and decreased ROS level in primary hepatocytes induced by TGF-β1 (2.12 ± 0.45 vs 3.23 ± 0.53,P＜0.01).Conclusion The mechanism of UA inhibiting hepatocyte apoptosis induced by TGF-β1 is likely to be that UA intervention reduced hepatocyte apoptosis by inhibiting NOX activation and decrease generation of ROS so as to down-regulate expression of CD95 in hepatocytes.
