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.

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.

AIM: To analyze the effect factors of trabeculectomy combined with intraoperative application of mitomycin C in the treatment of neovascular glaucoma.
METHODS: Fifty patients (50 eyes) with neovascular glaucoma collected from January 2013 to August 2015 in our hospital were treated by trabeculectomy combined with intraoperative application of mitomycin C. Single factor and multi factor variables analysis were used for effect factors of trabeculectomy combined with intraoperative application of mitomycin C in the treatment of neovascular glaucoma.
RESULTS: By results of single factor variable analysis,< 50 years old, preoperative intraocular pressure ( IOP) was ≥45mmHg and postoperative occurrence of anterior chamber hemorrhage were risk factors for treatment failure ( P < 0. 05 ), and gender, proliferative diabetic retinopathy and previous cataract surgery and prior photocoagulation were not the risk factors for failure (P>0. 05 ). By multivariate analysis, < 50 years old and postoperative occurrence of anterior chamber hemorrhage were risk factors for treatment failure ( P < 0. 05 ), and preoperative IOP≥45mmHg was not a risk factor (P>0.05). CONCLUSION: For patients < 50 years old with neovascular glaucoma, should be careful on the selection of surgical treatment. For high- risk patients, we should strengthen the monitoring and give timely intervention, which are helpful to improve the prognosis.

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.

Objective To evaluate the imaging quality of the non-contrast enhanced MR angiography of sampling perfection with application optimized contrasts using different flip angle evolutions (SPACE)in showing portal system and compared it with that of the contrast enhanced MR angiography of volumetric interpolated breath-hold examination (VIBE),and study its diagnostic ability in the detection of portosystemic and portohepatic collaterals.Methods Thirty consecutively cirrhotic patients with suspected of portosystemic and portohepatic collaterals were enrolled,and underwent SPACE followed by VIBE at 1.5 T MR scanner.The diagnostic accuracy of SPACE for the portal vein disease was evaluated by two doctors and compared it with that of VIBE.The contrast-to-noise ratio(CNR) and signal-to-noise ratio(SNR) of two MRA techniques were compared by using the Wilcoxon signed rank test.The quality assessment including scores of the portal vein segments and overall image quality were used the paired t test.Results Twenty-one patients were diagnosed as portal hypertension,including five types of portosystemic collaterals: esophageal varices (n =5),gastric fundic varices (n =11),splenic varices (n =5),paraumbilical varices (n =5) and cavemous transformation (n =2),and one patient was diagnosed as portal vein tumor thrombus.The diagnostic efficiency of SPACE was equivalent to that of VIBE.In SPACE,the SNR were 291 ± 57,301 ± 74,344 ±76 and the CNR were 231 ±59,242 ±73,286 ±76 at main portal vein,the left branch of portal vein and the right branch of portal vein,respectively.However in VIBE,the SNR were 185 ± 56,176 ± 52,182 ±52 and the CNR were 57 ±23,50 ±21,57± 19 at,respectively.Both SNR and CNR of portal vein segments in the former were better than those in the latter (t values were 7.691,7.418,7.946,15.746,13.508 and 13.880,respectively,P ＜ 0.05).There were no significant difference for the scores of displaying main,left branch and right branch portal vein and overall image quality in VIBE and SPACE (Z values were -1.496,-1.895,-1.496,-2.138,-2.324 and-1.328,respectively,P ＞ 0.05).The scores of displaying the distal branches of left and right portal vein were 2.08 ± 0.78,2.08 ± 0.78 in SPACE,and 1.75 ± 0.53,1.71 ± 0.55 in VIBE,respectively.It was better (Z =-2.138,-2.324,P ＜ 0.05) in SPACE than that in VIBE.Conclusion The SPACE has better visualization of portal vein distal branches than VIBE,and it can be applied for the diagnosis of the portal vein disease.
