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.

Genetic factors are an important cause of functional articulation disorder in children. This article reviews some genes and chromosome regions associated with a genetic susceptibility to functional articulation disorders. The forkhead box P2 (FOXP2) gene on chromosome 7 is introduced in details including its structure, expression and function. The relationship between the FOXP2 gene and developmental apraxia of speech is discussed. As a transcription factor, FOXP2 gene regulates the expression of many genes. CNTNAP2 as an important target gene of FOXP2 is a key gene influencing language development. Functional articulation disorder may be developed to dyslexia, therefore some candidate regions and genes related to dyslexia, such as 3p12-13, 15q11-21, 6p22 and 1p34-36, are also introduced. ROBO1 gene in 3p12.3, ZNF280D gene, TCF12 gene, EKN1 gene in 15q21, and KIAA0319 gene in 6p22 have been candidate genes for the study of functional articulation disorder.

At present, studies on traditional Chinese medicine (TCM) properties are mostly restricted to a single or two kinds of medicinal properties, but deviated from the holism of the theoretical system of TCMs. In this paper, the characteristics of pharmacological effects of different property combinations of TCMs distributing in the stomach meridian were take as the study objective. The data of properties of TCMs distributing in the stomach meridian was collected from the Pharmacopoeia of the People's Republic of China (2005). The data of pharmacological effects of TCMs distributing in the stomach meridian was collected from all of literatures recorded in Chinese Journal Full-text Database (CNKI) since 1980, Science of Chinese Materia Medica (Yan Zhenghua, People's Medical Publishing House, 2006) and Clinical Science of Chinese Materia Medica (Gao Xuemin, Zhong Gansheng, Hebei Science and Technology Publishing House, 2005). The corresponding pharmacological effects of property combinations of TCMs distributing in the stomach meridian was mined by the method of association rules. The results of the association rules were consistent with the empirical knowledge, and showed that different medicinal property combinations had respective pharmacological characteristics, including differences and similarities in pharmacological effects of different medicinal property combinations. Medicinal property combinations with identical four properties or five tastes showed similar pharmacological effects; whereas medicinal property combinations with different four properties or five tastes showed differentiated pharmacological effects. However, medicinal property combinations with different four properties or five tastes could also show similar pharmacological effects. In this study, the medicinal property theory and the pharmacological effects of TCMs were combined to reveal the main characteristics and regularity of pharmacological effects of TCMs distributing in the stomach meridian and provide a new way of thinking and method for revealing the mechanism action of TCMs distributing in the stomach meridian and discovering the pharmacological effects of TCMs distributing in the stomach meridian.

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.
