Expression and clinical significance of platelet-derived growth factor A in placenta of pre-eclampsia / 中华妇产科杂志

Objective To investigate the expression and clinical significance of platelet-derived growth factor A (PDGF-A) on placenta tissue from pre-eclampsia.Methods The expression of PDGF-A in the placenta of 38 pre-eclampsia patients and 22 normal pregnant women at third trimester was detected by immunohistochemistry method.Results (1)PDGF-A was mainly expressed in the cytomembrane and cytoplasm of cytotrophoblasts and the endothelial cell of capillary in placenta.(2) The rates of PDGF-A expression of cytotrophoblasts were 63% (24/38) in pre-eclampsia group and 32% (7/22) in normal pregnancy group,which exhibited significant difference (P ＜0.05).(3) The rates of PDGF-A expression of endothelial cell were 68% (26/38) in pre-eclampsia group and 27% (6/22) in normal pregnancy group,which also showed significant difference (P ＜0.01).(4)The rates of PDGF-A expression of cytotrophoblasts were 39% (7/18) in mild pre-eclampsia patients and 85% (17/20) in severe pre-eclampsia,which reached statistical difference (P ＜ 0.01).Conclusion The increasing expression of PDGF-A in cytotrophoblast and endothelial cell in placenta might confer the occurrence and progression of preeclampsia.

Postmenopausal Pyometra:Clinical Analysis of 8 Cases / 中华医院感染学杂志

OBJECTIVE To investigate the etiological factors,diagnosis and therapy of postmenopausal pyometra.METHODS The 8 cases of postmenopausal pyometra who hospitalized at China-Japan Union Hospital of Jilin University were retrospectively analyzed.RESULTS Postmenopausal pyometra was related with senile vaginitis,endometritis,not taking out of IUD after menopause promptly and endometrial cancer.There were 3 patients complicated with uterine perforation and 1 patient complicated with septic shock.4 patients had intrauterine dropsy with ultrasonic inspection.5 patients were cured with draining in cavitary uteri,and 3 patients were cured with operation.CONCLUSIONS The courses of postmenopausal pyometra are slow moving,with no evident clinical symptoms,which is easy to be misdiagnoed.Some have severe complications.We should prevent the disease aimed at carly diagnosis and therapy.

Clinical Trial of Weiyinkang with Lactasin in Treatment of Bacterial Vaginosis / 中华医院感染学杂志

OBJECTIVE To analyze the clinical therapeutic effect of a disposable vaginal adsorber for Weiyinkang and lacidophilin vaginal capsules(Yanhua) on bacterial vaginosis.METHODS A total of 140 patients were divided randomly and averagely into the group A and the group B.The two groups were treated respectively by metronidazole or Weiyinkang combined with lacidophilin vaginal capsules.RESULTS The effective rate of the groups B and A was 92.8% and 80.0%,respectively,with significant difference(?2 =4.93,P

Ultrasound Guidance of Central Vein Catheterization by External Jugular Vein Puncture / 中华医院感染学杂志

OBJECTIVE To develop technique of central vein catheterization by external jugular vein puncture under ultrasound guidance.METHODS A total of 224 patients with central vein catheterization by external jugular vein puncture were randomized into two groups: the control group was treated by routine manipulation and observed blood vessels by macroscopic observation;the patients from the observation group were placed catheters with the assist of ultrasound techniques.To record the one time achievement ratio of catheterization and incidence of phlebitis and thrombus.RESULTS Comparing the two groups,we found the observation group had higher one time achievement ratio of catheterization and lower incidence of phlebitis and thrombus than that of the control group.And there were statistical significances between the two groups(P

Polymorphism analysis of CYP1A1 MspI in ovarian cancer / 吉林大学学报(医学版)

Objective To detect the polymorphism of CYP1A1-MspI gene in patients with ovarian cancer.and discuss the relationship between the polymorphism ofCYP1A1-MspI gene and correspond cases' general materials and clinical materials.Methods The free peripheral blood samples of 81 cases confirmed to be ovarian cancer by postoperative pathology were collected preoperatively and the polymorphism of CYP1A1-MspI gene was detected.The clinical materials of the 81 cases with different genotypes were compared.The relationship between the polymorphism and clinical materials was analyzed.Results Among the 81 cases of ovarian cancer,there were 47 cases of wild type-genotype A(T/T)(58%),25 cases of mutation heterozygosis-genotype B(T/C)(31%),and 9 cases of mutation homozygosis-genotype C(C/C)(11%).The genotypic frequency distribution in patients aged from 12 to 29 was one case of genotype A(2.1%),5 cases of genotype B(20.0%),and no case of genotype C.The genotypic frequency distribution in patients aged from 30 to 49 was 12 case of genotype A(25.5%),8 cases of genotype B(32.0%),and 3 cases of genotype C(33.3%).The genotypic frequency distribution in patients aged from 50 to 69 was 31 case of genotype A(66.0%),8 cases of genotype B(32.0%) and 4 cases of genotype C(44.4%).The genotypic frequency distribution in patients aged more than 70 years was 3 case were of genotype A(6.4%),4 cases of genotype B(16.0%),2 case of genotype C(22.2%).There were significant differences of the ages of onset between patients with different CYP1A1-MspI genotypes (P

Methods for Sterilization of Skin in Injection Site of Myelosuppression Patients:Improvement and Application / 中华医院感染学杂志

OBJECTIVE To improve methods for the sterilization of skin in injection site of myelosuppression(BMD) patients,to raise the effect of sterilization and to prevent the infection of skin and soft tissue.METHODS A hundred and eighty-six myelosuppression patients were randomized to divide into two groups,an experiment group and a control group.The modified methods were adopted in the experiment group while the conventional methods were adopted in the control group.RESULTS The incidence rate of infection of skin and soft tissue in the experiment group was 9.4%,obviously lower than that of the control group,which was 35.6 %(P
