Objective: To investigate the therapeutic efficacy and mechanisms of ?-sodium aeacine in treating chest trauma.Methods: One hundred and sixty patients with chest trauma were randomly divided into two groups: the control group and the study group.The control group was treated by conventional method,while in addition to the conventional treatment,the study group was also treated with ?-sodium aeacine,10 mg of ?-sodium aeacine in 250 ml 10% glucose solution for intravenous drip,30 to 40 drops/min,twice a day for 10 days(one therapeutic course).Results: The effective and total effective rates of the study group were significantly higher than those of the control group(the effective rate(62.5% vs.22.5%) and the total effective rate(97.5% vs.66.3%),both P

Three nuclear type segeragants were isolated from a heterokaryon of Fusarium oxysporum f.sp.vasinfectum strain Ag149.Their cultural character and pathogenicity were different.The differences of their GC content for total DNA and nuclear DNA were between 0 1% to 0 4% and 0 4% to 0 8% respectively,as measured by thermal denaturation method.The 18S rDNA partial sequences of 1477 base pairs in these segregants were identical.

Objective To establish the quality standard for Haijinhuwei powder. Methods Corydalis Rhizoma, Angelicae Dahuricae Radix, Angelicae Sinensis Radix were identified by TLC. The content of tetrahydropalmatine was determined by HPLC. Results TLC spots were clear and specific.There was a good linear relationship between peak area and concentration of tetrahydropalmatine at the range of 10.78-107.8μg.mL-1(r=0.999 9).The average recovery rate was 96.57% and RSD was 1.40%(n=6). Conclusion All these results indicated that the developed TLC-HPLC method was proved to be reliable, accurate and specific, which could be used for the quality control of Haijinhuwei powder.

Objective To investigate the expressions of Wnt1 and β-catenin proteins in mammary cancer and its relationship with clinical pathological characteristics,and explore its role in the pathogenesis of breast cancer.Methods Immunoshistochemisty (SP method) was used to detect the expressions of Wnt1 and β-catenin proteins in adjacent tissue of breast cancer (n =15),breast hyperplasia tissues (n =25),and breast in vasive ductal carcinoma (n =80).SPSS 17.0 statistical software was used for analysis,such as count data with x2 test and correlation analysis with Spearman test,with significance level of α =0.05.Results The positive rate of Wnt1 and β-catenin in breast cancer group [62.5％ (50/80) and 68.8 (55/80)] was significantly higher than that in hyperplasia group [28％ (7/25) and 20％ (5/25)]and in borderline group [13.33 (2/15) and 13.33 (2/15)] with a significant difference (P ＜ 0.01).Positive expression of Wnt1 and abnormal expression of β-catenin in breast invasive ductal carcinoma were related to lymphatic metastasis (x2 =5.10,4.87,P ＜ 0.05).Abnormal expression of β-catenin was also related to the histological grading of breast invasive ductal carcinoma (x2 =5.61,P ＜ 0.05).The expressions of Wnt1 and β-catenin proteins in invasive ductal carcinoma showed a positive correlation (r =0.313,P ＜ 0.01).Conclusions The high level expression of Wnt1 protein and the abnormal expression of β-catenin protein might play an important role in breast carcinogenesis,and was related to lymph node metastasis.

In this study, microcalorimetry was adopted to establish a novel method for detecting the hemagglutination process of Radix Isatidis (Banlangen in Chinese, BLG), and to evaluate the hemagglutination activity diversity of BLG from various habitats. The hemagglutination biothermokinetics curves of positive reagent (phytohemagglutinin, PHA) and 8 batches BLG from different regions of the hemagglutination with 20% rabbit erythrocyte were recorded by microcalorimetry, then biothermokinetics parameters were abstracted, the hemagglutination utility of samples were calculated and analyzed by principal component analysis (PCA) and cluster analysis (CA), meanwhile the results were authenticated by micro-plate agglutination. It showed that the hemagglutination was an exothermic reaction, the reaction rate constant (k: 0.039-73.6 min(-1)), maximum reaction power (Pmax: -1 140.2 - 988.2 microW) and reaction enthalpy (Hi: -529.9 - 717.9 microJ) had good linear correlation with BLG extraction concentration (0.2-1.0 g mL(-1), r > 0.97), and PCA showed Pmax (531-1 335 microW) and Ht (585.2-989.2 microJ) could represent the hemagglutination activity diversity of BLG samples, just confirming with the results of micro-plate agglutination (the agglutination dilution was 3-11 respectively). According to the hemagglutination utility, the BLG samples from Good Agriculture Practice (GAP) regions, main producing area and general regions could be clustered correctly; meanwhile, the biothermokinetics curves with perfect distinctive fingerprint and specificity could give out more information for the quality control and evaluation for BLG. In conclusion, the microcalorimetry method established for detecting the hemagglutination activity of BLG samples on rabbit erythrocyte is sensitive and reliable, and could be adopted as an effective technique in detection aggulatination precisely, quantitatively and consecutively; and provide a novel approach for examining and evaluating quality for Chinese herbal medicine with aggulatinative activity such as BLG.
