Objective To establish alcoholic liver disease (ALD) model of rats. Method Rats were given wine by ig for 13 weeks. ALD were assessed by the level of serum glutamic-pyruvic transaminase (ALT), glutamic oxalacetic transaminase (AST), malonaldehyde (MDA) and pathological changes of liver. Result Over-dose wine can increase the level of serum ALT, AST, and MDA, decrease the level of serum albumin (ALB), and induce hepatic steatosis. Conclusion Alcoholic liver disease model of rats can be established by long-time and over-dose wine. The model can be applied in the research of ALD.

Objective To establish HPLC fingerprint for evaluating and controlling the quality of Gastrodia elata. Methods HPLC Analysis and similarity calculation were used for establishing fingerprint chromatogram and classifying 18 different original samples; LC-MS and pure compound comparisons were employed for the fingerprint peaks identification. Results HPLC Fingerprint chromatogram was cons- tructed with 27 fingerprint peaks, 17 of which were common fingerpring peaks and 12 main compounds were identified. According to the similarity to standardize herbal medicine, 18 samples could be classified three groups, Anhui-Henan, Shanxi-Sichuan, and Yunnan habitats. The two critical points were 0.80 and 0.58 for correlation coefficient and 0.88 and 0.73 for cosine values. Conclusion The selected fingerprint peaks are diagnostic for G. elata and the constituted HPLC fingerprint chromatogram could be used for identifying different habitats and served as a powerful tool for further quality control of G. elata.

Objective To study the chemical constituents of the EtOAc soluble fraction obtained from the stems and branches of Euonymus alatus with anti-myocardial ischemic effect. Methods Chemical constituents were isolated and purified by solvent extraction together with various chromatographic techniques, and the structures were identified by physicochemical properties and spectral analyses. ResultsFive compounds, 1-[3-?-D-glucopyranosyloxy)-4, 5-dihydroxyphenyl]-ethanone (Ⅰ), phenethyl alcohol 8-O-?-D-glucopyranosyl-(1→2)-?-D-glucopyranoside (Ⅱ), eugenyl-O-?-D-glucopyranoside (Ⅲ), hyperin (Ⅳ), and hesperidin (Ⅴ) were isolated. Conclusion Compound Ⅰ is determined as a new compound named guijianyuside. Compounds Ⅱ and Ⅲ are isolated from this plant for the first time.

Objective To investigate the variation of coagulation markers and its clinical value in type 2 diabetes patients. Methods The plasma levels of von Willebrand factor: antigen (vWF: Ag), thrombomodulin (TM), prothrombin fragment 1+2 (F 1+2 ) and P selectin were measured by ELISA in 65 patients with type 2 diabetes (including 33 patients with vascular complication) and 38 healthy people. Results The plasma level of vWF:Ag, TM, F 1+2 and P selectin in group of type 2 diabetes were significantly higher than that of normal controls ( P

Single-supervisor system is the widespread practice for graduates of clinical medicine at present. But in terms of education to clinical medical graduate students, students rotate in the departments of various disciplines for a long time, and there are more rotary department, resulting in some students' unbalanced learning development. Combined with the charac-teristics of the department of hematology, multi-supervisors training model was carried out to the rotating masters of other disciplines when they rotated in hematology department. With supervisor equipment and teaching implementation, we applied the principle of integrating theory with practice and trained students' innovation ability and doctor-patient communication ability. Compared with traditional single supervisor training pattern, multi-supervisors system can effec-tively improve the students' theoretical level, practical skills and comprehensive ability when the clinical medical graduate students rotate in the department of hematology.

Z-Ligustilide, a major phthalide isolated from a widely used traditional Chinese medicine Ligusticum chuanxiong, possesses various pharmacological activities including neuroprotective, anti-inflammatory, antiproliferative and vasorelaxing effects. However, it is unstable and inclined to degrade in natural conditions, which limits its study and application greatly. In this study, degradation behavior of Z-ligustilide and its degradation products stored at room temperature under direct sunlight were investigated and structure elucidated by HPLC-UV, UPLC-QTOF-MS and NMR. Z-ligustilide degradation and total five degradation products were generated and detected. Two degradation products were unequivocally identified as senkyunolide I and senkyunolide H by comparison with reference compounds. Another two degradation products were further isolated by semi-preparative HPLC and structure elucidated as (E)-6, 7-trans-dihydroxyligustilide and (Z)-6, 7-epoxyligustilide by 1H and 13C NMR, respectively. The degradation pathways of Z-ligustilide were finally proposed. Oxidation, hydrolysis and isomerization are the major degradation reactions.
