Objective To observe the influence of specific short hairpin siRNA targeting EGFR gene on apoptosis of human ovarian cancer Skov-3 cells in vitro. Methods A plasmid of a short hairpin siRNA targeting EGFR was constructed, and it was transfeeted into Skov-3 cell line by lipofectamine 2000. Human ovarian carcinoma cells of the line Skov-3 were cultured and divided into 3 groups: control group; non-specific group, transfected with non-specific plasmid vector; and specific group, transfected with specific small hairpin RNA expression vector. The expression of EGFR mRNA and protein were examined by RT-PCR and immunocytochemistry, Flow cytometry (FCM) was adopted to analyze quantitatively apoptotic cells in each group. Results After transfection of pshRNA-EGFR, mRNA and protein levels of EGFR gene in Skov-3 cells were obviously reduced. Flow cytometry analysis revealed that apoptosis could be induced in Skov-3 cells line transfected with pshRNA-EGFR in a time-dependent manner, no obvious apoptosis were detected in control group and non-specific group. Conclusion The plasmid expressive vector target at EGFR in our study is capable of suppressing EGFR expression of human ovarian cancer Skov-3 cells and inducing apoptosis, which provide a new way for the gene therapy of human ovarian cancer.

Objective To observe the effects of extracts of ginkgo leaves (EGL) on acute myocardial infarction, acute myocardial ischemia and blood hemorheology.Methods The effects of EGL on acute myocardial infarction were observed in dogs model induced by the ligation of anterior descending branch of left coronary artery; effects on acute myocardial ischemia were observed on rats model caused by intravenous injection of pituitrin and effects on blood hemorheology were observed in rabbits. Results EGL significantly reduced the myocardial infarction area, decreased the activities of lactate dehydrogenase and creatine phosphokinase in dogs, reduced the elevation of ST segment of electrocardiogram in rats with myocardial ischemia and decreased whole blood viscosity and plasma viscosity in rabbits. Conclusion EGL has protective effect against myocardial ischemic injury and can improve the parameters of blood hemorheology in rabbits. Its mechanism may be concerned with the reduction of the myocardial infarction area and infarction degree and the relief of acute myocardial ischemia.

Objective To seek the predictive value of pudendal nerve function that need preventive anti-incontinence surgery at the same time following pelvic prolapse surgery in severe pelvic organ prolapse (POP) patients. Methods Seventy women completed this study from January 2014 to June 2015 in Fuzhou General Hospital of Nanjing Military Command, dividing into four groups: POP with or without coexisting occult stress urinary incontinence (OSUI) in preoperation, women with persistent stress urinary incontinence (SUI) in postoperation, women without SUI in postoperation. The pudendal nerve function in preoperation was measured by using Solar Urodynamic Neuro Module, including pudendal nerve terminal motor latency (PNTML), and amplitude. Results There were statistical significance on bilateral PNTML between POP coexisting OSUI group and only severe POP group [(2.62±0.23) versus (2.40±0.26) ms in right of PNTML, (2.55 ± 0.21) versus (2.37 ± 0.30) ms in left of PNTML; all P<0.05], but no statistical significance on bilateral amplitude (P>0.05). Compared de novo SUI group with POP group in postoperation, de novo SUI group′s right of PNTML was significantly increased [(2.74 ± 0.16) versus (2.47 ± 0.26) ms; P<0.05]; and the right of PNTML was extending 2.5 standard deviation at least compared with the health′s [(2.10±0.20) ms]. Conclusions The PNTML of pudendal nerve of POP coexisting OSUI is severe than only severe POP, the velocity of nerve conduction is slowing, and PNTML extension has a predictive value for postoperative urinary incontinence. When the right of PNTML of preoperative POP increased by at least 2.5 standard deviations than health′s, the risk of SUI postoperative strongly increased, and a anti-incontinence surgery at the same time following pelvic prolapse surgery should be adviced.

ObjectiveTo investigate the role of T helper (Th) 22 and Th17 cells in the pathogenesis of severe preeclampsia.MethodsThirty women with severe preeclampsia who delivered in the Third Affiliated Hospital of Zhengzhou University from October 2014 to February 2016 were enrolled in the study. Thirty healthy pregnant women matched for age and gestational weeks were recruited as the control group. The frequencies of Th22 and Th17 cells in peripheral whole blood were determined by flow cytometry. The concentrations of interleukin (IL)-22 and IL-17A in plasma were detected by enzyme-linked immunosorbent assay. Independent two samplest-test, non-parametric test and Spearman correlation analysis were used for statistical analysis.ResultsThe percentage of Th22 and Th17 cells in the severe preeclampsia group were significantly higher than those in the control group, respectively[Th22 cells: 0.59% (0.39%-1.13%) vs 0.40%(0.23%-0.57%),Z=2.530,P=0.010; Th17 cells: 3.24% (3.02%-3.97%) vs 1.87% (1.53%-2.64%),Z=5.046, P=0.000]. So were the plasma levels of IL-22 and IL-17A[IL-22: 285.72 (247.63-306.69) vs 233.85 (184.92-258.38) pg/ml,Z=4.341,P=0.001; IL-17A: 27.53 (23.84-32.78) vs 17.36 (15.58-19.13) pg/ml,Z=4.924, P=0.000]. There was a positive correlation between circulating Th22 and Th17 cells in the severe preeclampsia group (r=0.534,P=0.015), while no correlation was found in the control group (r=0.345,P=0.136). Positive correlation was found in plasma level of IL-22 with Th22 cells (r=0.600,P=0.005), but not with Th17 cells (r=0.398,P=0.082) in the severe preeclampsia group.ConclusionsIncreased Th22 cells and high IL-22 concentrations in the peripheral blood of severe preeclampsia patients may indicate a self-defense mechanism in the maternal body. Th22 cells and Th17 cells may interact with each other.

Objective To investigate the expression changes and clinical significance of microRNA-155(miR-155) and chemokine receptor 4(CXCR4) in placental tissue from the patients with preeclampsia(PE).Methods Thirty pregnant women with severe PE(sPE) in the Third Affiliated Hospital of Zhengzhou University from December 2015 to February 2016 served as the sPE group,and contemporaneous 30 healthy pregnant women undergoing cesarean section due to the social factors served as the healthy control group(N).The real-time fluorescent quantitative PCR(RT-PCR) was used to detect the expression of miR-155 and CXCR4 mRNA in placental tissue and the relationship between miR-155 and CXCR4 levels was analyzed.The immunohistochemistry SABC methods were used to detect the expression of CXCR4 protein in villous cytotrophoblast(VCT) tissue microarray(TMA,42 cases in the normal control group 1,56 cases in the PE group) and extravillous cytotrophoblast(EVCT) TMA(29 cases in the normal control group 2,47 cases in the PE group) constructed by the same research group.Results (1) There was no statistically significant difference in the age,gestational age and pre-pregnancy body mass index(BMI) between the two groups(P>0.05).The differences of blood pressure between the two groups were statistically significant(P<0.05).The neonatal birthweight in the sPE group was significantly lower than that in the control group with statistically significant differences(P<0.05).The urine protein in the sPE group was significantly higher than that in the control group with statistically significant differences(P<0.05).(2)In the placental VCTand EVCT TMA,the age had no statistical difference between the two groups(P>0.05).The gestational weeks of the PE group were earlier than those in the N group 1,the systolic/diastolic blood pressure and urine protein were higher than those in the N group,the differences all were statistically significant(P<0.05),the neonatal birthweight was significantly lower than that in the N group with statistically significant differences(P<0.05).(3)The expression level of miR-155 mRNA in placental tissue in the sPE group was 1.53±0.92,which was significantly higher than 0.87±0.73 in the control group,the difference between the two groups was statistically significant(P<0.05).(4) The expression level of CXCR4 mRNA in the N group was 1.51±1.85,which in the sPE group was 0.54±0.38,the difference between the two groups was statistically significant(P<0.05).(5) In the sPE group,the miR-155 level and CXCR4 level in placntal tissue had a significant correlation(r=-0.773,P<0.05).(6) CXCR4 protein was expressed in VCT and EVCT TMA;the CXCR4 positive expression rate of the PE group in VCT TMA was 48.21%(27/56),which in the sPE group was 47.92%(23/48) and which in the early onset PE group was 53.66%(22/41),which all were significantly lower than 83.33%(35/42)in the normal control group,the differences all were statistically significant(P<0.05).(7)The positive expression rate of CXCR4 in the PE group in placent EVCT TMA was 48.94%(23/47),which in the sPE group was 50.00%(22/44) and which in the early PE onset group was 52.63%(20/38),which all significantly lower than 79.31%(23/29) in the normal control group,the differences all were statistically significant(P<0.05).Conclusion The level of placental tissue miR-155 is increased in the patients with sPE,while the level of CXCR4 is decreases obviously,both have a negative correlation,which may be associated with the pathogenesis of PE.
