Objective To investigate the distribution status of cytochrome CYP2C19 polymorphisms among patients with cardio-vascular diseases in Dongguan area .Methods A total of 1662 patients with cardiovascular diseases (CVD) in our hospital were se-lected .The peripheral blood was collected for extracting genomic DNA .The CYP2C19 genotype was detected by the polymerase chain reaction (PCR) combined with gene chip technology .The allele frequency and metabolic phenotype of CYP2C19 were com-pared between the CVD patients aged lower than 45 years and aged higher than 45 years old .Results Among 1662 cases ,713 cases (42 .90% ) were CYP2C19 extensive metabolizer ,740 cases(44 .52% ) were moderate metabolizer and 209 cases (12 .58% ) were poor metabolizer .The allele frequencies of CYP2C19﹡1 ,CYP2C19﹡2 and CYP2C19﹡3 were 65 .16% ,30 .08% and 4 .75% re-spectively .One hundred and four cases (40 .00% ) of extensive metabolisms were detected in the lower than 45 years old group ,104 cases(45 .38% ) of moderate metabolisms and 38 cases (14 .62% ) were detected .In the higher than 45 years old group ,609 cases (43 .44% ) of extensive metabolisms ,622 cases of moderate metabolisms and 171 cases(12 .20% ) of poor metabolism were detec-ted .The proportion of various genotypes had no statistical difference between the lower than 45 year old group and higher than 45 year old group(P>0 .05) .Conclusion Detecting CYP2C19 genotype for determining the genetic characteristics can evaluate the clopidogrel resistance risk and formulate the personalized anti-platelet therapeutic scheme .

Proteins extracted from two varieties of Chinese roses leaves were separated by two- dimensional polyacrylamide gel electrophoresis (2-DE) with immobilized pH gradient (IPG). Many difference proteins were isolated with molecular weights ranging 10-30 kDa and pI5-6. Three proteins of high levels observed in a gel were excised and identified using peptide mass fingerprinting and MS-MS. A summary of the identified proteins and their putative functions are presented. They are identified as eIF-5A、LEA protein and Hsp17. 5. Functions of these proteins in plant tolerance to high temperature were discussed.

Objective To evaluate the effect of combined treatment with gonadotropin-releasing hormone analog(GnRHa)and recombinant human growth hormone(rhGH)on predicted adult height(PAH)in girls with central precocious puberty(CPP).Methods Fifteen girls with CPP,whose growth velocity during GnRHa treatment had been less than 4 cm/year,were given additional rhGH treatment at a dose of 1 U?kg~(-1)?w~(-1),sc, for 4-13 months.Comparisons of growth velocity,height SDS for bone age(HtSDS_(BA))and PAH were performed before and after the combined treatment.Results During rhGH combined with GnRHa therapy,growth velocity increased significantly[(7.4?1.7)cm/year vs (3.2?0.7)cm/year baseline,P＜0.01].In 7 girls treated with rhGH and GnRHa for more than 9 months,growth velocity in the second 6 months[(6.5?1.0)cm/year]was slightly lower than that in the first 6 months[(8.8?1.1)cm/year],being both faster than that of baseline [(3.2?0.8)cm/year].There was a significant increase in rhGH-duration corrected change of HtSDS_(BA) [(0.35?0.15)/6 month vs (0.12?0.18 )/6 month baseline,P＜0.01]and PAH[(3.2_+1.4)cm/ 6 month vs (1.4?1.1)cm/6 month baseline,P＜0.01].Conclusion In girls with CPP showing a marked decrease in growth velocity during GnRHa treatment,the combined rhGH and GnRHa treatment remarkably improves growth velocity and PAH.

Objective To know the current conditions of institution set-up,personnels allocated and equipment supplied in county-,city-and country-level in endemic disease prevention and control.Methods Questionnaires,regarding institution set-up,personnels allocated and equipment supplied,was performed among staffs from administrative apartment and professional apartment.Results There were 31 institutions for endemic disease prevention and control in province level of our country(except Hainan Province),with one institution in each province.There were 308 institutions for endemic disease prevention and control in city level,and 23 cities did not have one.There were 2340 institutions for endemic disease prevention and control in county level,none in 502 counties.There were 20 provinces which had the professional crew of the endemic disease administration,but other provinces did not.The proportion of high-grade professional staff of province,city,county level was 24.84% (310/1248),17.05%(481/2821),5.31%(598/11 256)respectively.The averaged size of wdrking place at province-,city-and county-level was 2603.9,324.6,1227 m2.The averaged area of laboratory of province,city,county level was 1093.8,147.4 and 46.6 m2 respectively.The average quantity of equipments valued over ten thousand yuan at province-,city-and county-level is 15.5,2.2,0.6 respectively.Conclusions After the innovation of organizations for endemic disease prevention and control,the number of personnels devoting to this work has been curtailed,working place and equipment is insufficient,which hinders the prevention and control.

An antibiotic-producing bacterium, which was numbered as 20 #-5, was separated from the soil in Chongqing. It was identified as the member of pseudomonas. Gram positive bacteria are badly suppressed by it. The antibiotic secreted by 20 #-5 can endure 100℃ for half an hour, and it can also go through the ultrafiltration membrane with pores of 0.22?m.
