"Vessels Collateral Theory", as the inherit and development of "blood vessels" in Huangdi Neijing, is a systematic system by integrating severe vascular diseases. In this article, by taking cardiovascular diseases (CVD) as a cut-in point, roles of "minute collateral-microvascular" lesions in the occurrence and development of CVD were further explored. The interventional effect of collateral-unblocking medicines under the guidance of Vessels Collateral Theory was also in-depth explored, hoping to leading Chinese medical prevention and treatment of CVD.

Objective: To set up an HPLC method for the simultaneous determination of p-hydroxybenzoic acid plus o-hydroxy-benzoic acid and p-hydroxybenzeneacetic acid in Senecio scandens Buch. Methods:The column was a Shiseido( Fine Chemicals) Cap-cell Pak C18 (250 mm × 4. 6 mm, 5 μm) column at the room temperature. The mobile phase was methanol-water-formic acid (13∶87∶0. 5) at a flow rate of 1. 0 ml·min-1 . The detection wavelength was 240nm. Results: p-Hydroxybenzoic acid plus o-hydroxybenzoic acid had a favorable linear relationship within the range of 0. 025-0. 400 mg·ml-1 , the regression equation was Y=5. 94 × 106 X+2.46×104(r=0.9998),theaveragerecoverywas97.59% andRSDwas1.22%. p-Hydroxybenzeneaceticacidhadafavorableline-ar relationship within the range 0.05-0.80 mg·ml-1, the regression equation was Y=4.09 ×106X+1.12 ×104(r=0.999 8), the average recovery was 98. 07% and RSD was 1. 90%. Conclusion:The method is simple, feasible and reproducible. It can be used in the quality control of p-hydroxybenzoic acid plus o-hydroxybenzoic acid and p-hydroxybenzeneacetic acid in Senecio scandens Buch.

Objective To observe the effect of short-term treatment with metfbrmin on psychological distress and metabolic feature in patients with polycystic ovary syndrome(PCOS).Methods Ninety women were diagnosed as cases of PCOS based on the 2003 Rotterdam criteria.These patients were divided into three groups:group A,consisted of 26 subjects treated with mefformin only; group B,36 cases treated with metformin plus Dane-35 ; and group C,28 cases treated with placebo and Dane-35.The treatment was carried out for 3 months.Clinical and metabolic parameters were observed.The psychological distress was evaluated by the hospital anxiety and depression scale(HAD scale).Results Compared with group C,patients in group A and B showed significantly lower body mass index(BMI),waist circumference (WC),waist-hip ratio (WHR),serum fasting insulin,homeostasis model assessment for insulin resistance (HOMA-IR),total cholesterol (TC),triglyceride (TG),low density lipoproteincholesterol(LDL-C) levels as well as anxiety and depression scores,but higher high density lipoprotein-cholesterol (HDL-C) levels (all P＜0.05).Compared with group A,patients in Group B had significantly higher WC,WHR,and LDL-C levels(all P＜O.05).No significant differences in BMI,TG,HDL-C,anxiety and depression scores were found between group A and B (all P＞0.05).In group A,a positive correlation was found between the changes of metabolic feature (BMI,WHR,and HOMA-IR) and the changes of anxiety and depression scores (all P ＜0.05).Conclusion Short-term treatment with metformin will benefit patients with polycystic ovary syndrome,regarding psychological distress and metabolic features.

Objective To evaluate the correlation of the depths of detecting arteries vessel in transcranial dopplor(TCD) and child head circumference.Methods Five hundreds and eighty-eight health children were selected at random for the study. TCD ultrasonography was used to detect the optimal depths of arteries, middle and anterior and posterior cerebral arteries for each child, together with the head circumference.Results The data showed that the depths of detecting cerebral arteries significantly changed in different age groups, probably due to the growth of the head circumference.Conclusion There was close relationship between the depths of detecting cerebral arteries and child head circumference, which is of clinical significance.

Objective: To investigate the inhibitory effects of PTEN gene transfection combined with L-OHP on human cholangiocarcinoma cell line, QBC939, providing a new method for gene therapy of human biliary duct carcinoma. Methods: A eukaryotic expression vector containing PTEN gene was transfected into human QBC939 cells under mediation of lipofectamine and positive cell clones were selected and amplified. Expression of PTEN gene was detected by immunohistochemistry. MTT test was used to determine the in vitro activity of cells, electron microscope was applied to observe cell ultrastructure, and flow cytometry was used for determining the cell cycle and apoptosis. In vitro test was used to study the invasive ability of cells before and after treatment. Results: After transfected with PTEN gene, QBC939 cells had a higher expression of PTEN gene (P
