The active components from Centipeda minima were extracted by water or ethanol, and identified by FTIR spectroscopy and UV-visible spectrophotometer. The molluscicidal effect of aqueous extract and ethanol extract from Centipeda minima against Oncomelania hupensis was determined as referring to the WHO guidelines for laboratory molluscicidal test. Treated with over 2.0 g/L aqueous extract and ethanol extract for five days, the mortality of O. hupensis was up to 100%, and their LC50 for snails was 0.50 g/L and 0.62 g/L, respectively. The molluscicidal activity of aqueous extract was higher than that of ethanol extract. The main components of aqueous extract and ethanol extract were sesquiterpens lactones and sterols.

Objective:To evaluate the clinical efficacy of acupuncture plus tuina in treating cervical vertigo (CV).Methods:One hundred CV patients were randomized into an observation group and an acupuncture group by the random number table,with 50 cases in each group.The acupuncture group received acupuncture at Xiang Ba Zhen (eight acupoints on the nape);the observation group received tuina treatment in addition to the Xiang Ba Zhen acupuncture.The two groups were both treated once every other day for 10 sessions in total.The two groups were examined by transcranial cerebral Doppler (TCD) before and after the treatment,and their therapeutic efficacies were evaluated.Results:After the treatment,the mean velocity (Vm) of vertebral artery (VA) and basilar artery (BA) showed significant improvement in both groups (all P＜0.001);there were significant differences in the Vm of VA and BA between the two groups (both P＜0.05).The total effective rate was 100.0％ in the observation group versus 82.0％ in the acupuncture group,and the difference was statistically significant (P＜0.01).Conclusion:Xiang Ba Zhen acupuncture as a monotherapy or used together with tuina can improve CV,but Xiang Ba Zhen plus tuina can produce a more significant efficacy.

Objective To find out the cut-off value of rose bengal plate agglutination test(RBPT) in rapid diagnosis of brucellosis.Methods From May to June 2009,398 people who came to the outpatient department of Inner Mongolia Center for Endemic Disease Control and Research were diagnosed brucellosis by RBPT and tube agglutination test (SAT).Tube agglutination test as a gold standard,rose bengal plate agglutination test,its authenticity and reliability were evaluated.Results Taking positive predictive value 100.0％ as the selection standard,the cut-off value of RBPT was ++ which could be used to diagnose brucellosis.The sensitivity was 83.3％; the specificity was 100.0％; the Youden index was 0.832; and the compliance rote was 89.9％.Conclusion The cut-off value ++ of RBPT to diagnosis brucellosis is worthy of clinical promotion.

OBJECTIVETo clarity the original plants and the main application varieties of White Flos Gentianae.

METHODHerbal textual research, wild specimen collection, investigation and collection of the samples from Tibetan hospital, Tibetan pharmaceutical factory and medical material market were carried out simultaneously to identify the original plants of White Flos Gentianae.

RESULTThe results of varieties textual research and specimen identification showed that Gentiana szechenyii, G. purdomii and G. algida were in accord with the record of Tibetan herbal textual The three species above were the original plants of White Flos Gentianae. The identification of 20 batches samples showed that G. szechenyii was the main application variety. The other varieties were only used in Tibetan hospitals. All the samples above were flowering branches.

CONCLUSIONIt was necessary to strengthen the research on variety systematization of White Flos Gentianae make a further discussion on the taxonomy position of G. purdomii, G. algida and the white flos population. Its was also nessary to establish and improve the quality standard of different variety based on the principle of "one species, one name". The quality specification of White Flos Gentianae should be established and improved to standard clinical utilization and produce feeding. More study of resources investigation and cultivation of G. szechenyii should be carried on to meet the demand of produce and clinic.

Objective To explore the risk factors in elderly type 2 diabetes mellitus with cerebral infarction. Methods Retrospective investigarion was performed on 148 elderly hospitalized patients with type 2 diabetes.The patients were classified based on the presence or absence of cerebral infarction and compared with 60 controls.Logis- tic regression analysis was used to reveal the risk factors for cerebral infarction.Results The levels of systolic blood pressure(SBP),body mass index (BMI),fasting blood glucose (FBG),total cholesterol (TC),triglyceride (TG) and plasma fibrinogen(Fg) were higher in the patients with cerebral infarction[141.15?17.46)mmHg,(23.81?3.53)kg/m~2,(8.82?2.81)mmol/L,(5.69?1.15)mmol/L,(2.08?0.75)mmol/L and (4.08?0.65)g/L] than those without cerebral infarction[(129.78?14.65) mmHg,(22.18?3.22)kg/m~2,(7.06?1.72 )mmol/L,(5.09?1.12)mmol/L,(1.62?0.43)mmol/L and (3.48?0.58)g/L].The logistic analysis showed COUR,SBP,FBG, TC,TG and Fg were the independent risk factors for cerebral infarction.Conclusion Early intervention of the inde- pendent risk factors including SBP,FBG,TC,TG and Fg in elderly patients with type 2 diabetes was important for reduction and postponement of cerebral infarction.

Objective To study the relationship between the levels of uric acid in type 2 diabetic patients aged over forty years and lower extremity arterial disease(LEAD).Methods Lower extremities of 212 patients with type 2 diabetes were detected by high resolution color Doppler ultrasonography,and the levels of uric acid,fasting blood glucose and serum lipid were examined,which were applied to anylaze the relationship with diversity process of lower extremity arterial disease.Results The uric acid,low-density lipoproteins cholesterol(LDL-C),body mass in- dex(BMI),age and course in lower extremity arterial disease group was significantly higher than those without LEAD group(P

Objective To assess the MR characterization of coronary microembolization (CME)in an animal model as well as the evolution using MR cardiac cine,first-pass perfusion,and delay enhancement imaging.Methods Coronary microembolization models were established through intracoronary infusion of 120 000 microspheres (42 μm)into the left anterior descending artery in 1 1 pigs. Coronary angiography was performed at baseline and immediately after the injection of microspheres.MR imaging was carried out at baseline,6 hours,and 1 week after microembolization.Then,postmortem evaluation was performed using NBT and HE staining.Re-sults Coronary angiography after the injection of microspheres showed normal-appearing epicardial arteries in all animals.Coronary microembolization caused a significant decline in systolic wall thickening of the microembolized myocardial segments on cine MR ima-ges [from (42.6±2.0)% at baseline to (20.3±2.3)% at 6 hours and (31.5±2.1)% at 1 week after CME;P < 0.001 for both]. First-pass perfusion deficit was visualized at 6 hours after microembolization,and was less pronounced at 1 week.Hyperenhanced myocardium was found on delay enhancement MRI at 6 hours after microembolization in microembolized segments,but was not shown at 1 week. The microinfarcts were detectable microscopically through HE staining but invisible for the naked eye on gross NBT specimen.Con-clusion Coronary microembolization may cause a persistent decline in myocardial contraction and its MR characterization may vary with different stages.A combined use of different cardiac MRI techniques and follow-up examinations may be helpful for evaluating myocardial impairment due to coronary microembolization.
