Methods The study was designed as a random, double-blind placebo controlled clinical trial. 80 hyperuricacidemia patients were divided randomly into test group and control group (40 in test group and 40 in control group). The course of treatment was 28 days. Results 75 patients finished the trial (38 in test group and 37 in control group). After 28 days of treatment, the differences in reduction of UA, XOD, FINs, Homa-IR, TC, TG, Lp, CRP, ET, ?2-MG and elevation of HDL of the test group were statistic significance. No side effect was found in the trial. Conclusion Xuezhikang capsule has good clinical effect and safety in the treatment of hyperuricacidemia.

OBJECTIVEThis study aims to compare and determine a kind of nano-hydroxyapatite composite material with good antibacterial efficacy on Enterococcusfaecalis (E. faecalis) in vitro.

METHODSWe investigated the antimicrobial activity of four kinds of nano-hydroxyapatite composites, namely, silver/hydroxyapatite composite nanoparticles (Ag/nHA), yttrium/hydroxyapatite composite nanoparticles (Yi/nHA), cerium/hydroxyapatite composite nanoparticles (Ce/nHA), and hydroxyapatite nanoparticles (nHA), against E. faecalis in vitro using the agar diffusion and broth dilution method by measuring the growth inhibition zone and the minimum inhibitory concentration (MIC), respectively.

RESULTSThe agar diffusion test results showed that Ag/nHA displayed an obvious growth inhibition zone, whereas Yi/nHA, Ce/nHA, and nHA showed no influence on E. faecalis. The MIC value of Ag/nHA was 1.0 g.L-1, and the three other materials had no effect on E.faecalis even at the high concentration of 32.0 g.L-1.

CONCLUSIONAg/nHA display a potential antimicrobial efficacy to planktonic E.faecalis. Whereas, the three other kinds of nano-hydroxyapatite composites (Yi/nHA, Ce/nHA, nHA) show no influence.

The readjustment of the army establishments has resulted in the mergence of some sanatoriums into hospitals,which has given rise to a novel mode of management and offered a new opportunity for the development of sanatoriums.In the past four years since the mergence of our sanatorium into Nanjing General Hospital in 2004,we explored the mode of integrating recuperation with treatment and combined the resource advantages of ours with the technical superiority of the hospital,which led to an improvement of our competitive ability and comprehensive service and accordingly promoted the overall development of the sanatorium.

Currently,although surgical aortic valve replacement (SAVR) is still the golden standard in treatment of severe aortic stenosis according to the guideline,transcatheter aortic valve implantation (TAVI) is gradually becoming a common treatment for patients who are prohibitive or in high risk for SAVR.Recently,the valve manufacturers,including medical companies in China,are making their utmost to develop valve device,leading remarkable results achieved by TAVI.With the complications being controlled,TAVI displays promising future.It is likely that TAVI is expected to become a substitute for SAVR to treat patients with aortic stenosis or even aortic regurgitation.

Aim To explore the inhibitory effect of isobavachalcone (IBC)on migration and invasion of
tongue squamous cell carcinoma Tca81 1 3 cells and its possible mechanism.Methods Tca81 1 3 cells were
treated in different concentrations of IBC in vitro.Cell proliferation was detected by MTT;Wound healing as-say and Transwell chamber assay were used to detect the ability of cell migration and invasion;Western blot was applied to detect the expression of Akt,p-Akt, MMP-2 and MMP-9 proteins.Results IBC could in-hibit the proliferation of Tca81 1 3 cells in a concentra-tion-and time-dependent manner.IBC can reduce cell migration and invasion.Western blot showed that IBC could an decrease the expression of p-Akt,MMP-2 and MMP-9 proteins in a concentration-dependent manner.
However,the level of Akt was not affected by the con-centration of IBC treatment.Conclusion IBC could inhibit the proliferation, migration and invasion in Tca81 1 3 cells and its mechanism may be associated with the down-regulation of MMP-2 and MMP-9 pro-teins and the inhibition of phosphorylation of upstream Akt.

Objective To investigate the expression of CD147 and its significance in human cervical carcinoma. Methods Western blotting and immunohistochemical staining were used to detect CD147 expression in cervical cancer or normal cervix uteri tissues. Results CD147 protein was expressed in all of cervical carcinomas (41/41, 100.0%) and most of normal cervix uteri tissues (11/12, 91.7%). CD147 with different molecular weights were present in cervical tissues. The percentage of CD147-positive cells and the expressional level of CD147 were higher in cervical carcinomas than in normal cervix (P<0.05). Conclusion CD147 might be recognized as a marker of cell proliferation. High expression of CD147 in cervical carcinomas suggests that it might be a potential target for cervical carcinoma therapy.

BACKGROUND:Endothelial progenitor cells are recruited into local vascular injury under the injury-induced stimulation, and then differentiate into mature endothelial cells that are thereby involved in angiogenesis and endothelial repair. OBJECTIVE:To investigate whether endothelial progenitor cells can al eviate renal injury and improve renal function of ischemia/reperfusion injury (I/R) rats. METHODS:Peripheral blood samples extracted from Sprague-Dawley rats were used to isolate and culture endothelial progenitor cells using density gradient centrifugation. Twenty-two male Sprague-Dawley rats were randomized to three groups:I/R group, normal control group, and endothelial progenitor cells group. In the I/R and endothelial progenitor cells groups, the right kidney was removed and the renal artery and vein of the left kidney were occluded for 40 minutes to establish I/R models in the rats, and then endothelial progenitor cells (5×109/L, total y 1 mL) or solvent was transplanted via the artery of the left kidney into the left kidney. In the normal control group, the experimental procedure was same as that in the I/R group except for occlusion of the artery and vein of the left kidney. Renal and blood samples from three groups were col ected at day 1 after operation. Peripheral blood CD34 and vascular endoethelial growth factor receptor 2 expressions were determined using flow cytometry and immunofluorescence methods, serum creatinine and urea nitrogen were tested, and immunohistochemistry observation was used for CD34 observation. RESULTS AND CONCLUSION:Compared with the normal control group, serum creatinine and urea nitrogen levels were significantly increased, and tubulointerstitial CD34 expression was decreased in the I/R group (P<0.05). Endothelial progenitor cells treatment largely decreased the levels of serum creatinine and urea nitrogen, and increased CD34 expression (P<0.05). These findings indicate that transplantation of endothelial progenitor cells contributes to renal protection in I/R rats.

Objective:To observe and compare the therapeutic effect of metoprolol by routine increasing dose method and rapid titration method on acute myocardial infarction (AMI).Methods:A total of 60 inpatients,who were di-agnosed with AMI within 24h and without contraindications for metoprolol,were randomly divided into two groups:routine therapy group (received metoprolol using routine methods,the dose was added in seven days)and rapid ti-tration group (metoprolol was added in three days using titration).The dosage maintained with 190 mg/d after both groups reaching the target dose of 190mg/d;then therapeutic effects were observed in both groups.Results: ①There were no re-myocardial infarction,rehospitalization caused by heart failure and sudden death etc.in both groups;② Patients received echocardiography in outpatients after three months.Compared with routine increasing dose group,there was significant reduction in left ventricular end-diastolic diameter [LVEDd,(55.00±7.56)mm vs.(50.00± 5.81)mm]and significant rise in left ventricular ejection fraction [LVEF,(49.13 ± 10.18)% vs. (57.84±10.34)%]in rapid titration group,P <0.01 both.Conclusion:Rapid titration method could make the pa-tients rapidly reach the targeted dose of metoprolol and inhibit renin release earlier,block the renin-angiotensin sys-tem,and improve myocardial remodeling and cardiac function.
