Objective Study the effect of Chuanxiongsu(ferulic acid) combined perindopril or perindopril alone in the treatment of essential hypertension (EH). Methods Sixty patients with EH were divided into two groups randomly and single blindly: group A received Chuanxiongsu combined with perindopril, while group B received perindopril alone(4-8 mg/d) only for four weeks. Plasma endothelin-1 concentration(ET-1) and nitric oxide (NO) concentration were determined with radiommunoassay(RIA). Blood pressure was monitored before and after treatment. Thirty healthy volunteers served as controls. Results SBP in group A was lower than that in group B(138.9?8.1 vs group B 143.1?8.5)mm Hg, P

Objective To observe the effects of perindopril on changes of endothelin(ET)and atrial natriuretic peptide (ANP) in patients with essential hypertension (EH).Methods Thirty patients with EH were given with perindopril for four consecutive weeks.Plasma ET and ANP were examined with radioimmunoassay (RIA) before and after treatment,with thirty healthy volunteers as controls.Results Plasma levels of ET and ANP were higher in EH groups before treatment than those in controls (P＜0.01),and decreased significantly after treatment than those before treatment (P＜0.01).Conclusion The influence of perindopril on ET and ANP is correlated to its hypotensive effects in EH patients.

Objective To compare the mid- and long-term results of tricuspid valve (TV) repair with or without an annuloplasty ring. Methods Two hundred seventy-seven patients underwent TV repair at our division (Sep. 2001 to Sep. 2008) ,of which 203 had, predominantly, a De Vega or Kay procedure (non-ring group) and 74had an annuloplasty with an artificial ring (ring group). TV pathology mainly was functional (secondary) and several with rheumatic leaflets involvement. Concomitant procedures consisted of mitral valve surgery in all patients,aortic valve surgery in 81 ,and coronary bypass in 19. Clinical and echocardiographic data followed for 1.5 to 3.5years were obtained. Results Postoperationally,the mid-term(1.5 years) follow-up was 100% completed and the long-term follow-up for 3. 5 years was 89. 9%. The recurrence of TV regurgitation (TR) of moderate and lower degree was not significantly different(χ2 = 1.3128, P= 0.26) in the 1.5 years follow-up between the two group,whereas the recurrence of TR of moderate to severity degree was significantly less in the ring group (χ2 =5. 8159,P =0.023).In the long term follow up,the TR in the ring group (25%) was significantly lower than that of 15% in the non-ring group (χ2 = 4. 9328, P = 0.036) . There are higher proportion of patients developing to moderate TR in the non ring group(34%) than in the ring group (10%) (χ2 =7. 9120,P =0.005). The TR developed fast in the ring group,increasing from 18% at 1.5 years follow up to 10% at 3.5 years follow up (χ2 = 2. 1327, P = 0.016),whereas it was relatively stable in the non-ring group,with 7% at 1.5 year follow up and 10% at 3.5 year follow up. Conclusions Placement of an annuloplasty ring in patients undergoing TV repair could remarkably improved the mid and long terum outcome. In clinic practice, we should be more positive to the functional TR and prefer to the procedure with annuloplasty ring.

BACKGROUND: The hypospadias is usually repaired by the autologous tissues by surgery, but there is few local tissues available in patients with urinary leakage after I stage surgical repair, while other tissues require complex operations and induces large injury.OBJECTIVE: To observe the tissue engineered patches in the treatment of hypospadias, and to evaluate the biocompatibility and clinical efficacy.METHODS: Eight patients with urinary leakage after surgery for hypospadias repair underwent tissue patch I stage urethroplasty from January 2009 to October 2010. The curative effect and perioperative histocompatibility were determined.RESULTS AND CONCLUSION: Eight patients were uniformly successful after I stage surgery. One out of the 8 patients appeared mild urinary leakage and well cured by topical fibrin glue. There was no fever, local edema, skin tube and flap necrosis occurred during the postoperative hospital stay. All patients were followed up for 4-6 months, patients were observed to urinate standing, without urinary leakage, refractory prepuce edema and other complications.

A sensing method based on high-speed camera is proposed to recognize human arm motion in this paper. A sensing system for human arm motion was established. A fast image processing algorithm was developed to accurately extract marker positions in the image. Angle parameter results were further improved with the instantaneous joint center principle. The human motion information results can serve as the research references of medical treatment, gym, bionics, and so on. The sensing method can also be applied to other fields of the human motion recognition.
