Objective To determine the relative factors of the onset of repeated ectopic pregnancy. Methods The clinical data of the first time ectopic pregnancy of 28 cases with repeated ectopic pregnancy were analysed, and compared with those of 56 cases of non-repeated ectopic pregnancy onsetting at the same period. The factors measured included: age at onset of disease, age at first coitus, gravidity, parity, methods of contraception, duration of amenorrhea,duration of vaginal bleeding, serum ?-human chorionic gonadotropin level, volume of intraperitoneal bleeding, types of ectopic pregnancy, methods of therapy and inflammation evidence of fallopian tube. Logistic regression analysis was performed to determine the relative factors for onset of repeated pregnancy. Results The risk factors and its odds ratio (OR) from the multivariate analysis were as follow: anastomosis of the tube(62.74, P=0.043), positive evidence of inflammation of the tube (54.85, P=0.000), no contraception (11.29, P=0.002), contraception by condom occasionally (4.75, P=0.046); the protective factors and its OR were as follow: therapy being salpingectomy and sterilization of the opposite tube(0.06, P=0.049), oral contraception (0.10, P=0.050) and pharmacotherapy (0.33, P=0.002). Conclusions The risk factors of onset of repeated ectopic pregnancy include: anastomosis of the tube, positive evidence of inflammation of the tube, no contraception and contraception by condom occasionally; the protective factors include: therapy being salpingectomy and sterilization of the opposite tube, oral contraception and pharmacotherapy.

Objective To investigate measures of preventing asphyxia neonatorum in order to reduce the rate of asphyxia neonatorum.Methods Clinical datas on a total of 78 cases of critical asphyxia neonatorum from the year 2003～2004 in Longgang Central Hospital were collected and analyzed.Related high risk factors and effective precaution measures of reducing the rate of asphyxia neonatorum were studied.Results The rate of asphyxia neonatorum from January 2003 to December 2004 was 4.22%,of which it was 1.70% of critical asphyxia neonatorum and 8% of treated deaths.The first seven related factors to critical asphyxia neonatorum of this group were:fetal distress(47%),premature delivery(49%),umbilical factors-torsion,prolapse,shortening(32%),breech presentation(26%),high risk PIH(14%),monstrosity(6%),placental abruption and placenta praevia(6%).Conclusion Effective measures of reducing critical asphyxia neonatorum are to strengthen the monitoring of pregnant women and their antenatal care so as to find and treat PIH early and correct breech presentation in time,try to reduce premature delivery,find early and properly treat fetal distress and oafs and prohibit illegal accouchement.

Objective To investigate the relationship between intrauterine growth retardation (IUGR) and en docrine parameters so as to assess the effects of the main endocrine factors on IUGR. The concentrations of growth hormone (GH), insulin, T3, T4 and TSH were measured in umbilical cord blood, amniotic fluid and maternal serum. Methods The samples were collected from 23 pregnant women who were diagnosed as the full term IUGR, 42 normal full term pregnant women with normal infants' weight were taken as control. Growth hormone and insulin were mea sured by radioimmunoassay. T3, T4 and TSH were investigated by micro-radioimmunoassay. Results The concentra tions of growth hormone, insulin and T4 in umbilical cord blood were lower in IUGR than that in control group(GH 4. 63μg/L vs 7.01μg/L, insulin 10. 68μIU/ml vs 31.44μIU/ml, T4 87. 39nmol/L vs 138. 10nmol/L. P ＜0. 05, 0. 05 and 0. 05, respectively). The TSH concentration in umbilical cord blood was higher in IUGR than in control group (10. 84μmIU/L vs 5. 75μmIU/L, P ＜0. 01). The concentration of growth hormone in maternal serum and the concen tration of insulin in amniotic fluid were also lower in IUGR group than in control group(GH 1.77μg/L vs 2.74μg/L, P ＜0. 01, insulin 5. 84μIU/mi vs 15. 64μIU/ml, P ＜0. 01). Conclusion This study confirms that full term neonates with IUGR are abnormal in endocrine factors. The inadequacy of growth hormone may be one of the causes of IUGR. The relative scarcity of growth hormone and insulin seems to be a factor to compromise the fetus' metabolism. Be sides, the early hypothyrosis of infants with IUGR might protect them from unfavorable environment in the uterine.

ObjectiveTo investigate the age distribution of serum prostate specific antigen (PSA) and explore its correlation with fasting blood glucose(FBG)and lipid in the male elderly.MethodsThe levels of FBG,triglyceride (TG),low-density lipoprotein (LDL-C),high density lipoprotein (HDL-C) and PSA were reviewed in 2903 elderly men (aged ≥ 60 years) in our hospital.The subjects were classified into 6 groups by age,and PSA levels were compared among groups.The correlations of FBG,TG,LDL-C,HDL-C with PSA were analyzed using multiple linear regression analysis.Results The level of PSA had the trend to increase with age.Positive association of TG,LDL with serum PSA level,but negative correlation between HDL and serum PSA level were noted in the group aged 60-64 years (r=0.10,0.15,0.12,P＜0.05).In the group aged 66-69 years,there was negative relationship between FBG and serum PSA(r= 0.10,P＜0.05).No relationship could be found in other groups (P＞0.05).ConclusionsPSA level may increase with age,but without relation with FBG,TG,LDL-C and HDL-C.

Objective To investigate the causes of hypothermia in severe trauma patients as well as the effects of warming nursing.Methods Toally 100 severe trauma patients with hypothermia were engaged in the study during January to December 2014.Their temperature was monitored and recorded,the causes analyzed so that the warming nursing measures were done to them.Results Among the 100 patients,59 contracted hypothermia,with the rate of 59.0％ before operation,28 contracted hypothermia during operation,with the incidence rate of 28.0％.The causes of hypothermia included injury,anaesthesia,exposure and fluid resuscitation.The nursing measures included pre-treatment before anaesthesia,avoidance of more exposure and intraoperative warming.Conclusions For the patients with severe trauma,the hypothermia during the operation can be caused by injury,anaesthesia,exposure and fluid resuscitation.The warming nursing can reduce the incidence of hypothermia so as to increase their survival rate.

Objective To provide basis for routine fetal cardiac screening by comparing the ultrasound detection rate of fetal heart defects between the high-risk and low-risk population.Methods According to the questionnaire about maternal risk factors,all 7165 pregnant women were divided into two groups.The high-risk group included 2147 cases and the remained 5018 were considered as low-risk population.Routine fetal heart screening was performed by the four-chamber view,left and right outflow tract views.If some cardiac malformations were found,the detailed fetal echocardiography would be performed.Both the detection rate of fetal cardiac defects and distribution of the relevant risk factors were analyzed.Results Ninty-five(1.33%)cases of congenital heart disease were found in our study,32(1.49%)cases from highrisk group and 63(1.26%)cases from low-risk group.No significant was found between the two groups (X2=0.635,P＞0.05).Karyotyping were performed prenatally in 23 of 95 fetal congenital defects cases by cordocentesis and chorionbiopsy,and 11(47.83%)cases of concomitant chromosomal abnormality were found.Conclusions Routine fetal screening for congenital fetal diseases should be performed in non-selected population for the similar detection rate of fetal defect in high-risk and low-risk group.

Objective To evaluate the value of tomographic ultrasound imaging(TUI)in the fetal heart screening.Methods One hundred and ten volume datasets acquired from normal fetal heart in the second trimester with spatio-temporal image correlation(STIC) were evaluated offline with TUI. The Bmode and CDFI static images as well as the dynamic loops of one cardiac eycle could be reviewed simultaneously. The visualizing rate and ultrasonic scores of the 4 chamber view,outflow tracts and 3 vessels (and trachea)view obtained from TUI and routine ultrasonography for fetal heart screening were respectively compared. Results Among all 110 cases,the visualizing rate of 4 chamber view,outflow tracts and 3 vessels(and trachea) view were respectively 100%(67),88.9%(45),80.0%(45),84.4%(32)in Bmode and 100%(33),86.2%(25),50.0%(14),100%(4)in CDFI under the same fetal Dositi.n.No significant differences of the visualization rate were found between TUI and routine screening either in Bmode or in CDFI(P＞0.05). The median score of 4 chamber view of TUI in B-mode was little higher than that in routine screening,while the right outflow tract of screening in CDFI significantly higher than that of TUI(P＜0.05). Conclusions The visualizing rates and qualities of TUI are sufficient for fetal heart screening offline as well as routine ultrasonography online in second trimester.

Objective To investigate the effect of an anti-HER-2 engineered antibody,chA21,on the expression of MMP-2 and TIMP-2 in human ovarian cancer SKOV3 cells that highly express HER-2.Methods After exposure to chA21 at concentrations of 6 mg/L and 12 mg/L for 36 hours,respectively,the expression of MMP-2 and TIMP-2 proteins was detected by immunocyctochemistry.SKOV3 cells were inoculated into nude mice to establish animal models.The mice were respectively administered with normal saline and chA21(30 mg/kg) via injection twice a week for 6 consecutive weeks,and then were killed after 44 days' administration of the drugs.Immnohistochemical staining of MMP-2 and TIMP-2 was observed on tissue microarray sections.Results After exposed to chA21,TIMP-2 protein was increased(P
