OBJECTIVE: To establish a method of molecular biology to identify the authenticity and varieties of Penis et Testis Cervi rapidly, simply and accurately. METHODS: The mitochondrial DNAs (mtDNA) of dried Cervus nippon Penis, Cervus elaphus. L Penis, Penis et Testis Bovis and commercial products were extracted and purified with column chromatography. A pair of primers were designed for PCR special amplification of mtDNA according to cytochrome b gene sequence in the cervidae mtDNA GenBank; the products of PCR were analyzed for the single strand conformation polymorphism (SSCP) by denaturing polyacrylamide gel electrophoresis (PAGE). RESULTS: The positive control samples and some commercial products showed clear single strand DNA (ssDNA) bands with different mobility, but the negative control sample and some other commercial products showed nothing. CONCLUSION: Column chromatography method is a good way for getting mtDNA with high purity and less destruction of structure for the follow-up special PCR amplification; SSCP technique not only shows ssDNA bands of mutually complementing clearly, but also reveals the difference of mobility among ssDNAs from all samples directly. For that reason, the technique of PCR-SSCP will be reliable and feasible to indentify the authenticity and varieties of products from cervidae.

Objective To study the value of upbuilding heartcare network in metabolic syndrome.Methods Body mass index,waist and breech circumference,waist hip ratio,blood pressure,fasting plasma glucose,lipid profile, plasma insulin,and urine albumin were determined.Various risk factors were assessed and intervention measures were made.Results Various risk factors in metabolic syndrome were decreased after treatment intervention for 3,6 months,1 and 2 years.Conclusion Taking integrated intervention measures with heartcarc network was significant for hygiene.

In order to provide the basis for confirming the medical talent cultivating target of new century, we have finished the research on the request to the doctors in new century, and the purpose is to make our medical colleges cultivate more medical talents to meet the need of the 21st century.

Objective:To investigate the expression of Bcl-2 and Bax in renal tissues of patients with hepatitis B virus- associated glomerulonephritis(HBV-GN).Methods:Twenty HBV-GN specimens with complete nephrology data and 10 normal renal specimens were randomly chosen for the present study.Cell apoptosis was detected by means of terminal deoxynucleotidyl transferase mediated d-UTP nick end labeling(TUNEL)and the apoptotic index was calculated;immunohistochemistry was used to detect the protein expression of Bax and Bcl-2.ResuLts:The apoptotic index in HBV-GN group was obviously higher than that of the control group;the apoptotic cells were mainly distributed in the proximal and distal renal tubules and the collecting duct epithelial cells,seldom seen in the glomerular cells.The expression of Bcl-2 in HBV-GN patients was predominately present in the renal tubular epithelia cells(positive in the plasma,membrane and nuclear);the expression of Bax was found in both glomerular cells and renal tubular cells,mainly in tubular epithelial cells,seldom seen in Bowman's capsule or glomerular mesangial region.Conclusion:Apoptosis in the kidney of HBV-GN patients mainly occurs in the renal tubular epithelial cells;expression of Bax and Bcl-2 is mainly in the renal tubular epithelial cells,suggesting that the injury of tubular interstitial damage may be one of the important factors for the development of HBV-GN.

This study was aimed to create a method for content determination of quercetin, luteolin and kaempferol in flowers of Dimocarpus longan Lour. from different habitats of Guangxi province by HPLC. The samples were sepa-rated on the Hypersil C18 column (250 mm í 4.6 mm, 5 μm) which was eluted with methanol-0.2% phosphoric acid solution (47:53) with detective wavelength at 360 nm, flow rate at 1.0 mL·min-1, and column temperature at 30℃. The results showed that this method had a good linear relationship within the range of 0.18 to 2.88 μg for quercetin, 0.059 to 0.944 μg for luteolin, and 0.024 to 0.384 μg for kaempferol (r = 0.9999). The average recovery rate was 100.06% (RSD = 1.72%), 99.77% (RSD = 1.18%) and 98.67% (RSD = 1.99%, n = 9), respectively. It was conclud-ed that this method is simple, rapid, reliable and with good repeatability, which can be used in the quality control of flowers of Dimocarpus longan Lour.

Objectives To study the psychological characteristics of children with attention deifcit hyperactivity disorder (ADHD). Methods Human ifgure drawings (HFD) as a projective technique was performed in 107 children with ADHD aged (8.69 ±1.48) years old (6.5~11.5 years), and 107 matched healthy children. Characteristic features of the HFDs in children with ADHD, and correlations between emotional indicators of the HFDs and factors of child behavior checklist (CBCL) were assessed and com-pared with the control group. Results Signiifcant differences in emotional index were found between ADHD and healthy chil-dren, including bad body composition, short arms, long arms, big ifgure, omission of hands and omission of feet (P<0.05). Nega-tive correlation was found between the HFDs emotional index and the factors of activity and social ability in the CBCL (P<0.05), but a positive correlation was found between the HFDs emotional index and behavioral problem (P<0.05). Conclusion Human ifgure drawings can relfect some emotional characteristics of children with ADHD, and when combined with CBCL, it can pro-vide evidence for diagnosis and intervention for ADHD.
