Objective :To explore influence of CYP2C19 gene polymorphism on clopidogrel resistance after percutane‐ous coronary intervention (PCI) in patients with coronary heart disease (CHD).Methods :A total of 100 CHD pa‐tients ,who were treated and received PCI in our hospital ,were selected .There were 24 cases with clopidogrel re‐sistance (CR ,CR group) and 76 cases without CR (NCR ,NCR group).According to CYP2C19 genotype ,patients were divided into rapid metabolism CYP2C19*1／*1 (n＝49) ,medium metabolism CYP2C19*1／*2 (n＝28) and*1／*3 (n＝11) ,and slow metabolism CYP2C19*2／*2 (n＝9) and *2／*3 (n＝3).Relationship among differ‐ent genotypes ,CR ,maximum platelet aggregation rate (MPA) and incidence of major adverse cardiovascular events (MACE) were analyzed .Results :With rapid metabolism CYP2C19*1／*1 as the base ,there was significant rise in CR risk in medium metabolism (CYP2C19*1／*2 and *1／*3 ,OR＝4. 16 ,5. 03 , P＜0.05 both) and slow metab‐olism (CYP2C19*2／*2 and *2／*3 ,OR＝7.04 ,17. 6 , P＜0.01 both ) ,medium metabolism increased by 4. 16 and 5. 03 times respectively ,while slow metabolism increased by 7. 04 and 17. 60 times respectively .Compared with rapid metabolism genotype ,there were significant rise in MPA and incidence rate of MACE in medium and slow me‐tabolism genotypes , P＜0.05 or ＜0. 01 ;incidence rate of MACE in CR group was significantly higher than that of NCR group (20. 8% vs.5. 3%, P＝0.02).Conclusion : CYP2C19 gene polymorphism possesses certain influence on CR after PCI in CHD patients .Those with medium or slow metabolism genotypes are more likely to suffer from CR ,higher MPA and incidence rate of MACE .

Objective To investigate the constitutive characteristics and the change trend of gynecologic malignant tumors in hospitalized patients in Guangxi Zhuang Autonomous Region over the recent 20 years.Methods Clinical data of 8009 in-patients who suffered from gynecologic malignant tumors in 23 hospitals from 1985 to 2004 in Guangxi Zhuang Autonomous Region were analyzed,with respect to the tumor types and change trend.Results(1)The leading 4 types of malignant tumors were cervical cancers, ovarian cancers,endometrial cancers,and malignant trophoblastic tumors according to the constitutive ratios of the tumors.The constitutive ratio of cervical cancer patients rose year by year,from 17.48% during the 1985-1989 period to 49.25% during the 2000-2004 period(P0.05).(2)The occurring age of cervical cancers became younger obviously,from≥60 years old dropped to
