As the dressings currently used in clinic settings unflat shape in general, they can't be fitted completely on occiput, heel, elbow, knee and other body parts unflat. This paper developed one kind of foam dressing of special shape based on local anatomy. The foam dressing is waterproof and air permeable, it can cover the wound closely enough to prevent bacteria from invasion and infection. With a saturated absorption ratio of 1: 8 or higher, it can keep the wound clean and moisture by absorbing large amounts of wound inflammatory secretions and is almost completely permeable to oxygen and carbon dioxide. Assuring safety and effect meanwhile, it has better outcomes than common dressings in the same application settings.

Objectives: To assess the feasibility and stability of right ventricular outflow tract (ROVT) pacing under current technology by comparing the results of ROVT pacing with the traditional right ventricular apex (RVA) pacing. Methods: A total of 42 patients (at mean age of 63.5±10.4 years) without structural heart disease were randomly divided into two groups. RVA pacing group (n=14),and RVOT pacing group(n=28). An active fixation lead was implanted in all patients whose pacemaker could automatically measure the pacing threshold every day. The operation time,X-ray exposure time and lead parameters detected during the operation were collected to evaluate the feasibility of RVOT pacing. The complications related to lead and implantation procedure and the trend of threshold change during the follow-up time were used to assess the stability of RVOT pacing.Results: There were no statistic differences between RVA pacing group and RVOT pacing group in terms of operation time,X-ray exposure time and lead parameters. In RVOT group,the change of threshold during acute period was similar to those in RVA group (P=0.23). Chronic pacing threshold was also comparable between two groups,mean threshold at 6 months follow-up time was 0.55±0.11V and 0.54±0.09V at 0.4 pulse width in RVA group and RVOT group respectively (P=0.787).Conclusion: RVOT pacing was feasible and stable in operation time and lead characteristics compared with the conventional RVA pacing under current pacing technology.

Objective To observe the effect of nerve growth factor(NGF)and electro-acupuncture(EA) on learning and memory in rats with cerebral ischemia.Methods An experimental model of cerebral ischemiareperfusion was established in 40 rats,who were then randomly divided into a model group,a sham operated group,a NGF group,an acupuncture group and a NGF plus acupuncture group.Three weeks were allowed for the recovery of the blood-brain barrier lesion caused by ischemia-reperfusion before intravenous injection of NGF(10μg/kg,once daily for 15 days)via the vena caudalis.In the two acupuncture groups,this was administered in combination with EA at the Baihui(DU20)and Yamen(DU15)acupoints(frequency 100 Hz,2 mA,20 min/time,once daily for 15 days).Morris' water maze test was used to assess any changes in spatial learning and memory abilities.Results The ischemic rats showed significant learning and memory disorders compared with the sham-operated group.In the NGF group,the rats' learning and memory abilities did not impmve significantly compared with the model group and the EA group.Significantly better learning was observed in the NGF+EA group compared with the model group,the EA group and the NGF group.Conclusion NGF combined with EA can improve the learning and memory abilities of rats with learning and memory dysfunction caused by cerebral ischemia-repedusion.

Object To observe the effect of Guizhi Fuling Capsule (GFC) on prostatic hyperplasia in rats induced by testosterone propionate. Methods Seven days after the male rats were castrated, testosterone propionate (3 mg/kg) was sc injected in rats. Meanwhile, the rats were administered GFC (2.16, 1.08, 0.54 g/kg) once a day, and the treatment continued for 30 d. An hour after the final administration, the rats were put to death, and the weight and volume of prostates were measured. The construction of prostate cells was also observed under light microscope. Results In the GFC group, the weight and volume of prostate was significantly decreased compared with that in the model group (P

Objective To study the mechanism of blood-lipid regulation of the effective fractions from the extracts of Radix Salviae Miltiorrhizae(RSM)or Fructus Crataegi(FC),as well as their interaction.Methods The serum-drug of RSM and FC extracts were prepared by orthogonal design L_16(215).Amphotercin B cell model and RT-PCR method were used to examine the effects of the serum-drug of RSM and FC extracts on endogenous cholesterol biosynthesis in Chinese hamster ovary(CHO)cells and the expressions of cholesterol 7?-hydroxylase(CYP7A)mRNA in BRL cells.Results Ethanol(75%)and ammonia extracts of RSM obviously increased the absorbance(A)in the experiment of amphotercin B cell model and the expression of CYP7A mRNA in BRL cell line.The extracts of FC had no direct effect on cholesterol metabolism by themselves,but they were in synergism with the extracts of RSM.ConclusionThe extracts of RSM have a blood-lipid regulation by inhibiting endogenous cholesterol biosynthesis and increasing CYP7A mRNA expression,and maybe have a better effect when the extracts of FC are used together.

Objective To study the factors influencing the outcome of patients suffering from in-hospital ventricular fibriUation (IHVF), as there have been few studies focusing on this topic. Methods Patients with IHVF collected in a single cardiac center were classified into a successful group and a failure group. Data relevant to the predicting factors of the two groups were compared. Results There were 206 events in the analysis. The most common underlining disease was coronary artery disease (CAD), especially acute myocardial infarction (AMI). On multiple logistic regression analysis, it was shown that the independent predictors for failure of defebriUation were higher NYHA class (OR 1.7, 95% CI 1.3-2. 2,P <0.001), higher blood potassium level (OR 2.9, 95% CI 1.9-4.3, P =0.007) and adrenaline usage (OR 25.0, 95% CI 11.5-55. 1, P <0.001). In a AMI sub-group, 56. 9% of the IHVF events occurred within the first day of AMI, and the occurrence descended with time going on within 2 weeks. Before the occurrence of IHVF, the patients with right coronary artery as the infarction related artery (IRA) often suffered from(8/9, 88.9%) bradycardia (R-R interval > 1 s), but those with left anterior descending artery as IRA often showed (8/12, 66.7%) tachycardia (RR interval < 0.6 s). Conclusions The common disease causing IHVF is CAD. The worse the heart function, the higher the rate of IHVF and the worse theprognosis. It IHVF not induced by hypokalemia and use of adrenaline in resuscitation predict lower successful defibrillation rate.
