OBJECTIVE:To study the protective effect of the injection of puerarin combined with salvianoli acid B(Sal B)on rats with myocardial ischemia reperfusion injury (MIRI). METHODS:62 rats were randomly divided into sham operation group, model group,puerarin group(20 mg/kg)and puerarin(20 mg/kg)-Sal B group(mass ratio of 1:0.5,1:1,1:2,respectively),10 in each group. Except for sham operation group,rats in other groups were reduced for MIRI model. After 180 min of reperfusion, kinase(CK),lactate dehydrogenase(LDH),superoxide dismutase(SOD),malondialdehyde(MDA)in serum and percentage of myocardial infarction size of rats were detected. RESULTS:Compared with sham operation group,CK,LDH,MDA levels in se-rum of rats in model group were obviously increased (P<0.01),SOD level was obviously decreased (P<0.01);and percentage of myocardial infarction size was obviously increased (P<0.01). Compared with model group,CK,LDH,MDA levels in serum of rats in each administration group were decreased(P<0.05 or P<0.01),SOD levels were obviously increased(P<0.05 or P<0.01),and indexes changed the most obviously in puerarin-Sal B group(1:1);percentage of myocardial infarction size was obvi-ously decreased(P<0.01),and the percentage of myocardial infarction sizes in puerarin-Sal B group(1:1)and group(1:2)were less than Puerarin injection group (P<0.01). CONCLUSIONS:Compared with Puerarin injection alone,puerarin combined with Sal B by injection can more effectively inhibit the cardiomyocyte injury and decrease myocardial infarction size after MIRI,with best efficacy when quality ratio is 1:1.

ObjectiveTo standardize the process in making the model of acute regional cerebral ischemia in Sprague-Dawley rats, and to economize time and material.MethodsRegional cerebral ischemia rat's models were induced and modified according to Koizumi's method.ResultsThe time duration was controllable and the volume of cerebral infarct was determined by adverting the approaches such as the preparation of suture, anaesthesia of the animal, and the details of surgical operation.ConclusionThe acute regional cerebral ischemic model in rats made by Koizumi's method is stable and reliable, and is easy for the beginner to carry out under limited conditions.

Biomass is a renewable resource, which can be transformed into useful chemical products. The effects of dilute hydrochloric acid on the hydrolysis of steam explosion pretreatment of corn straw were studied. This article developed the application research of ergosterol using corn straw hydrolysates as fer- mentation substrates. The results showed that when corn straw was hydrolyzed with 1.5% hydrochloric acid, temperature at 90?C, hydrolysis for 3 h and the corresponding solid to liquid ratio at 10%, the reducing sugar content can reached up to 53.3% and cellulose conversion efficiency was 79%. The optimal fermental pa- rameters were as follows: 6.0 oBx of corn straw hydrolysates, corn concentration steep water at 4%, pH 7.5, 10% of inoculation, 28?C cultivated for 32 h. Under these conditions, the yeast biomass up to 8.5 g/L and the ergosterol content up to 2.35%. The infrared spectrometer and the X-ray diffract meter used to characterize of crystallite structure.

OBJECTIVE To analysis the effect of air disinfection by using nanometer light catalysis decontamination machine in operating room. METHODS By compare the effectiveness of air disinfection both by using nanometer light catalysis decontamination machine and ultraviolet rays light. RESULTS The result of tests is 0 CFU/m~2 by nanometer light catalysis decontamination machine and 33.3 CFU/m~2 by ultraviolet rays light in unmanned environment;By different groups: F=220.423,P=0.000,P

Wet age-related macular degeneration (AMD) is one of major causes of blindness in elder people.Intraocular injection of anti-vascular endothelial growth factor (VEGF) -A regimen has made big breakthrough for the treatment on choroidal neovascularization of wet AM D,while long-term follow-up and necessary retreatments are the key issues to remain obtained visual acuity.Multiple strategies of wet AMD have been used in following-up and retreating based on the visual acuity,optical coherence tomography (OCT),ophthalmoscope and fluorescein fundus angiography (FFA) in abroad.However,there also are major differences in the patient' s composition,treatment habits and distribution of medical sources in China from Western.So we suggest to standardize the follow-up and retreatment strategies about intravitreal injection of VEGF-A for wet AMD as to achieve a better effectiveness.OCT-guided individual follow-up and retreatment strategies should be very helpful for maintaining a long-term efficacy,minimizing the treatment time and reducing medical cost.

Objective To observe the characteristic changes in cardiac function and to raise diagnostic accuracy and sensibility.Methods 39 silent myocardial ischemia and 58 angina and 46 age-matched healthy subjects and 62 obsolete myocardial infarction underwent myocardial tomography imaging and gated ventricular imaging.Covariance analysis was used to compare difference between SPECT imaging and parameters of function.The age was tested as covariate factor,then SNK-Q test and multiple comparison were carried on.Results The silent myocardial ischemia and angina showed reversible radioactive defect or fixed defect.Most of myocardial SMI showed single peak exempt TPFR.EF,PFR and PER showed remarkably statistical difference (P<0.01).The multiple comparison of PFR and PER was increased according by OMI,AN,SMI and negative control group (P<0.05).Conclusions The myocardial damage and PFR,PER in SMI is lower than that in AN group,which have no remarkably influence on the parameters of diastolic and retractile function in left ventricular.

OBJECTIVETo observe the effect of combined therapy with Bailing Capsule (BC) and benazepril on the levels of urinary albumin excretion rate (UAER) and C-reactive protein (CRP) for exploring its protective effect on early diabetic nephropathy.

METHODSSixty patients with early diabetic nephropathy were randomly assigned to the control group treated by benazepril alone, and the treated group treated by BC and benazepril, and the treatment lasted for 16 weeks. The changes of UAER and CRP levels were measured to estimate the protective effect of the combined therapy.

RESULTSLevels of 24h urinary protein, UAER, CRP were (0.85 +/- 0.32) g/24 h, (83.34 +/- 38.27) microg/min, (2.67 +/- 1.72) mg/L before treatment in the control group, and (0.43 +/- 0.17) g/24 h, (71.22 +/- 31.12) microg/min, (1.05 +/- 0.78) mg/L after treatment and they were (0.87 +/- 0.31) g/24 h, (81.59 +/- 35.69) microg/min, (2.55 +/- 1.66) mg/L before treatment in treated group, and (0.25 +/- 0.29) g/24 h, (57.32 +/- 31.11) microg/min, (0.49 +/- 0.38) mg/L after treatment respectively, all of them decreased after treatment in both groups, showing significant differences as compared with those before treatment (P<0.05, P< 0.01), and the reduction in the treated group was more significant (P<0.01); meanwhile, levels of serum creatinine, fasting blood glucose and HbA1c had somewhat decrease, showing no statistical difference with those before treatment (P >0.05).

CONCLUSIONCombined use of BC and benazepril could significantly lower the UAER and CRP levels in patients with early diabetic nephropathy to alleviate the renal impairment, showing an effect better than that of using benazepril alone.

Ethnic medicine industry is facing many problems such as narrow market, exhaustion of resource, decline of ethnic medicine and no qualified successors. Sustainable development theory was utilized to analyse the elements and problems of ethnic medicine industry, and the counter measures were put forward to get rid of the predicament and to realize the sustainable development which depends on the ethnic medicine resources, national medicine, industrial policy, personnel training and modern technology. The development issues of ethnic medicine industry can be solved by the coordination of enterprise, government and public. Finally the ethnic medicine can provide better services for society.
