Objective To study and analyze the clinical efficacy of zoledronic acid in the treatment of osteoporotic intertrochanteric fracture in elderly patients. Methods 100 elderly patients with osteoporotic unstable intertrochanteric fracture treated in our hospital from February 2014 to July 2016 were selected and randomly divided into the control group and the experimental group. There were 50 patients in each group. The control group received routine treatment (calcitonin), and the experimental group was treated with zoledronic acid.The clinical indicators of the two groups were compared and analyzed. Results After the corresponding treatment, the VAS scores of the experimental group and the control group were (0.36±0.42) and (0.34±0.40), and there was no statistical significance. The excellent rate of hip joint function was 82% in the control group, and the excellent and good rate of hip joint function in the experimental group was 80%, which was not statistically significant. In addition, there were no statistically significant differences in fracture healing time and complications between the two groups. After 1 years, the hip bone mineral density and the lumbar vertebral bone mineral density were (0.78±0.05) g/cm2, and (0.85±0.06) g/cm2 were significantly higher than those in the control group,with statistical significance (P<0.05). Conclusion Zoledronic acid in the treatment of senile osteoporotic unstable intertrochanteric fracture clinical effect is remarkable,can increase bone mineral density in a large extent, the joint recovery had no effect, has clinical significance.

Objective To investigate the proliferation and differentiation characteristics of fibroblast like synovial cells(FLS)in rheumatoid arthritis(RA)in vitro and the mechanism of the immunosuppressive effect of differentiation inducers, such as all trans retinoid acid(ATRA), ealcitriol [1,25(OH)_2D_3] and dexamethasone(DEX). Methods FLS of knee synovial tissues from RA patients were cultured and identified in vitro in the presence or absence of ATRA, 1,25(OH)_2D_3 and DEX respectively. Synoviocyte proliferation in RA were measured by MTT colorimetrie assay and the survival fraction(SF)of FLS was evaluated. Cell cycle of FLS was observed using fluorescence-activated cell sorting(FCS)method in RA patients. Results The identified synovial cells in patients with RA were FLS(Vimentin and Fibronectin expression was positive), and hadn't been transformed or differentiated to adipocytes and osteoblasts with the three inducers. The SF of all RA-FLS interfered by ATRA, 1,25(OH)_2D_3 and DEX was much lower than that without drugs vehicle group in RA-FLS(P

Objective To investigate the proliferative characteristics of fibroblast-like synovial cells (FLS)in osteoarthritis in vitro and the mechanism of the immunosuppressive effect of total glucusides of paeony(TGP).Methods FLS of OA and non-inflamed synovium(NS)were cultured and identified in vitro in the presence or absence of TGP.After incubation,the survival fraction(SF)of FLS was evaluated by MTI' and the TNF-?,IFN-?and bFGF level in cultured FLS supernatant was measured by ELISA.The expression of FLS c-los mRNA and cell cycle of OA-FLS was observed by RT-PCR and flow eytometry respectively at the same time.Results No statistical significant differences were noted between the OA and NS FLS in pro- liferating double time.High doses of TGP suppressed FLS-SF more evidently in OA patients than in NS(P0.05).Conclusion High dose TGP can inhibit OA-FLS proliferation,modulate cy- tokine secretion and c-fos expression in OA.This suggests that TGP has immunosuppressive effect on OA syn- ovitis,probably by preventing the synovial hypertrophy in OA.

Backgroud and Objective Proline-rich tyrosine kinase2(Pyk2) is a Ca~(2+) sensitive,non-receptor tyrosine protein kinase.Previous reports showed Pyk2 involved in development of left ventrieular hypertrophy. The present paper aimed to study the effects of valsartan on ventricular hypertrophy and its effect on the expression of Pyk2 in myocardium in renovascular hypertensive rats(RHR).Methods Two-kidney and one-clip(2K1C) renal hypertensive model was established in Sprague-Dawley rats by chronic partial occlusion of left renal artery,and ran- domized to receive valsartan (30 mg/kg?d) or without treatment for 4 or 8 weeks.Left ventricular mass to body mass ratio was measured.Pyk2 protein expression and phosphorylation was detected by Western blotting.Results Blood pressure,left ventricular mass to body mass ratio,Pyk2 activity in myocardium of RHR were increased gradu- ally.Valsartan reduced BP and prevent myocardial hypertrophy(P

OBJECTIVETo observe the effect of low molecular weight heparin calcium (LMWHC) combined Compound Danshen Injection (DI) on nephrotic syndrome patients with early onset severe preeclampsia.

METHODSTotally 80 nephrotic syndrome patients with early onset severe pre-eclampsia were randomly assigned to four groups voluntarily, i.e., Group A (22 cases, treated by magnesium sulfate), B (19 cases, treated by magnesium sulfate plus LMWHC), C (21 cases, magnesium sulfate plus DI), D (18 cases, magnesium sulfate plus LMWHC and DI). Umbilical arterial S/D ratios, amniotic fluid index (AFI), prolonged gestational age, placenta weight, neonatal weight, and Apgar score were compared among the four groups.

RESULTSCompared with before treatment in the same group, umbilical arterial S/D ratios decreased in the four groups (P <0. 05). AFI decreased in Group A, while it increased in Group B, C, and D (P<0. 05). Compared with Group A at the same time point, umbilical arterial S/D ratios decreased, and AFI increased in Group B, C, and D (P <0. 01 , P <0. 05). Prolonged gestational age and neonatal weight were increased in Group B, C, and D (P <0. 01, P <0. 05). Placenta weight were increased in Group B and D (P <0. 05). Apgar scores at 1 and 5 min were improved in Group D (P <0. 05). Compared with Group B and C at the same time point, umbilical arterial S/D ratios decreased, and AFI increased in Group D (P<0. 05). Compared with Group B, prolonged gestational age and placenta weight were decreased in Group C, but prolonged gestational age and placenta weight were increased in Group D (P <0.05). Compared with Group C, prolonged gestational age, placenta weight, and neonatal weight were increased in Group D (P <0. 05).

CONCLUSIONTreatment of nephrotic syndrome patients with early onset severe pre-eclampsia by LMWHC combined DI could prolong gestational ages, obviously improve prenatal outcomes, with better effect obtained than using any of them alone.

The aim of this study is to clarify whether edaravone postconditioning had protective effect against renal ischemia/reperfusion injury and to compare the protective effect between ischemic postconditioning and edaravone postconditioning. Rats were subjected to 45 min ischemia followed by 24 h reperfusion. The rats were randomly assigned to seven groups: a sham-operated control group, an ischemia/reperfusion group, an ischemic postconditioning group, a normal saline vehicle postconditioning group and an edaravone postconditioning (1, 3, and 6 mg x kg(-1)) group. Renal function was assessed by serum creatinine and BUN concentration, while histological damage of renal tissue was assessed with HE staining. MDA content and SOD activity of renal tissue were determined. TUNEL staining was performed to analyze the apoptosis of the tubular epithelial cells, the protein level of Bcl-2 and Bax in renal tissue was examined by Western blotting. Compared to the ischemia/reperfusion group, edaravone postconditioning significantly decreased serum creatinine and BUN concentration, and ameliorated histological damage of renal tissue. MDA was less after 24 h reperfusion in the edaravone postconditioning group than that in the ischemia/reperfusion group, consistent with an increase in SOD activity. In addition, edaravone postconditioning decreased TUNEL-positive cells and Bax expression, and increased Bcl-2 expression. Results detected in the edaravone postconditioning group showed no significant difference from the ischemic postconditioning group. Edaravone administered during the last 3 min of ischemia, prior to reperfusion induces a pharmacological postconditioning in vivo against renal ischemia/reperfusion injury in rats. This protection is similar to that observed with ischemic postconditioning.

Objective To investigate the proliferation characteristics of fibroblast like synovial cells (FLS)in osteoarthritis in vitro and the mechanism of the immnnosuppressive effect of T-614 [N-(3-formy- lamino-4-oxo-6-phenoxy-4H-chromen-7-yl)methanesulfonamide ] on them.Methods FLS of OA and non- inflamed synovium(NS)were cultured and identified in vitro in the presence or absence of T-614.After incu- bation,the survival fraction(SF)of FLS was evaluated by MTT,cell cycle was observed using fluorescence - activated cell sorting(FCS)method and the expression of c-fos and COX-2 mRNA was examined by RT- PCR in FLS of OA patients.Results No statistically significant difference was noted between the OA and NS FLS in proliferation ability and cell cycle.High dose T-614 suppressed FLS SF obviously in OA and NS sta- tistically(P＜0.05),whereas the inhibition degree was not different between the two kinds of FLS.The agent induced cell apoptosis and reduced the accumulation of c-fos mRNA in OA-FLS at dose 1000 ml/L,prolonged G_1 term and shortened S term at dose 200 ml/L.The expression of COX-2 mRNA in OA FLS was suppressed obviously by T-614 at dose 1000 ml/L.Conclusion OA FLS do not display a distinct activated unlimited viability compared with NS cells,without stimulated by proinflammatory cytokine in vitro.High dose T-614 moderately inhibits the proliferation and differentiation of FLS,directly affects gene of the c-fos and COX-2 expression in OA,which may contribute to its immunosuppressive effect on OA'synovitis.
