Objective: To study the chemical constituents in the roots of Aconitum bulleyanum Diels. Methods: The air-dried roots of A. bulleyanum were powdered and extracted by methanol with percolation. After removing the solvent under reduced pressure, the crude extract was dissolved in 1. 5％ HCl solution, and then basified to pH 9 by NaOH (5％) and extracted by ethyl acetate to ob-tain crude alkaloidal extract after ethyl acetate removal. The alkaloidal extract was isolated and purified by column chromatography, and their structures were identified based on spectral analysis ( 1 H-NMR, 13 C-NMR, MS) . Results:Totally 12 diterpenoid alkaloids were isolated from A. bulleyanum and characterized as foresaconitine (1), crassicauline A (2), chasmanine (3), talatisamine (4), 14-debenzoyl-franchetine (5), pengshenine A (6), crassicautine (7), yunaconitine (8), franchetine (9), liljestrandisine (10), transconitine B (11) and pseudoaconine (12). Conclusion:Compounds 3-7, 10-12 are isolated from this plant for the first time.

Objective: To construct a high effective eukaryotic expre ss ing vector containing mcpr1 gene. Methods: mcpr1 gene w as amplified by PCR from the plasmid T-easy/ mcpr1, then PCR product was in serted into eukaryotic expressing vector pcDNA3.1/V5-His B. The positive recomb inant was identified by PCR analysis, HindIII and BamHI restriction analysis and Sequence analysis. Results: A 400 bp DNA fragment was amplified from the recombinant. Sequence analysis and restriction digest demonstrated tha t the mcpr1 gene was successfully inserted into pcDNA3.1/V5-His B plasmid. Conclusion: The eukaryotic expressed vector pcDNA3.1/V5-His B/ mcpr1 has been successfully reconstructed.

Objective To observe the effect of Jiangzhi Yigan Chongji (JYC) on the nonalcoholic fatty liver tissue PPAR? and Trx mRNA expression,and explore the mechanism of treating fatty liver. Methods The model was made by feeding high-fat diet and the rats were divide into 3 groups:normal group,model group and treated group. Result Expression of liver tissue PPAR? and Trx mRNA in the model group were both decreased. JYC can increase their expression of liver tissue of model rats. Conclusion It is likely to be one of the important mechanisms for JYC in treating nonalcoholic fatty liver.

Traditional Chinese medicine (TCM) diagnostic methods contain inspection, auscultation-olfaction, inter-rogation and palpation. The clinical doctor collects information through the four diagnostic methods. Various symp-toms of the disease are especially used as the main evidence to determine different diseases and to identify the syndrome. Therefore, the TCM four diagnostic methods are the basic means of disease understanding in TCM. This article collected and analyzed clinical data in order to summarize the unique features and focused aspects of TCM four diagnostic methods application on TCM surgery and dermatology. This article was aimed to provide new ideas for TCM four diagnostic methods in the clinical diagnosis of dermatological diseases.

Background:Ulcerative colitis(UC)is a chronic and nonspecific intestinal inflammatory disease and its pathogenic mechanism has not yet been clarified. Intestinal mucosal immune function disorder may play a key role in the pathogenesis of UC. Aims:To investigate the effects of Wumeiwan on expressions of δ-opioid receptor(DOR),β-arrestin1 and Bcl-2 in rats with colitis. Methods:Fifty-six Sprague-Dawley rats were randomly divided into model group,Wumeiwan group, mesalazine group and blank group. Rats in model group,Wumeiwan group and mesalazine group were administered intrarectally with 5% TNBS and 50% ethanol to induce experimental colitis. After colitis models were established,rats in Wumeiwan group and mesalazine group were administered intragastrically with Wumeiwan and mesalazine suspension, respectively,and rats in model group and blank group were given intragastrically with 0. 9% NaCl solution,all for 15 days. On day 16,all the rats were sacrificed and colon samples were obtained. Protein and mRNA expressions of DOR,β-arrestin1 and Bcl-2 in colonic tissue were determined by immunohistochemistry and real-time PCR,respectively. Results:The inflammatory injury in colonic tissue of rats with experimental colitis was significantly attenuated when treated with Wumeiwan,Protein and mRNA expressions of DOR,β-arrestin1 and Bcl-2 in colonic tissue of model group were significantly higher than those of blank group(P < 0. 05). Protein and mRNA expressions of DOR,β-arrestin1 and Bcl-2 in colonic tissue of Wumeiwan group and mesalazine group were significantly lower than those of model group(P < 0. 05), however,no significant differences were found between the two groups(P > 0. 05). Conclusions:DOR-β-arrestin1-Bcl-2 signal transduction pathway may play a central role in the pathogenesis of UC. Intervening this signaling pathway may be one of the mechanisms of attenuating UC by Wumeiwan.

Objective To analyze the ultrasonographic characters in the patients with scalp arteriovenous malformations and evaluate the value of ultrasonography in the diagnosis.Methods The head soft tissue mass,bilateral superficial temporal artery and occipital artery in 9 patients with scalp arteriovenous malformations were examined using high frequency ultrasound.The caliber,systole peak velocity(Vmax),diastole end velocity(Vmin) and resistance index(RI) of the abnormal vessels were recorded.The findings were compared and analyzed with those of the cerebral angiography and ultrasonography in 40 healthy volunteers.Results These lesions displayed subcutaneous hypoecho or no echo region full of reticular or honeycombed darkspace by two dimensional ultrasound,rich signals with flickering and bright mosaic flow by color Doppler and the spectra of high velocity and low resistance by pulsed Doppler.Arterial spectral shape with high velocity and low resistance were found within the lesions and Vmax( 77.7 ? 14.3 ) cm/s,Vmin( 44.3 ? 5.7 )cm/s,RI= 0.41 ? 0.09 .Sixteen feeding arteries with spectra of high velocity and low resistance were checked out,their caliber,Vmax and Vmin were higher and RI lower significantly than those in the control (P

Objective To investigate the data of outpatient children,survey on the clinical characteristics of vertigo and provide baseline information for clinical diagnosis and treatment.Methods The questionnaires and clinical tests data of 553 children with vertigo were retrospectively analyzed.Results All the children and their parents received interviews,otological examinations and clinical audiological tests. Their ages were between 4 and 15,with the average at 9.51?2.83. ①The males were 341(61.66%) and female 212 (38.34%),with the gender ratio of male to female as 1.61:1. ②The peak of the age curves of treatment and the first onset of vertigo was 9.51 and 8.62-year-old,respectively. ③20.98% of children with vertigo had normal results with peripheral vertigo more common in the rest.④The semicircular canals were more likely to dysfunction if their relatives had vertigo or car sickness.Conclusion The age of children mostly with vertigo is between 6 and 11 years with more males than females. Vertigo itself can be a symptom but on the other hand,some show no positive signs even with vertigo.
