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 effects of stromal cell-derived factor 1 (SDF-1) and an CXC chemokine receptor 4 (CXCR4) antagonist (AMD3100) on the invasion and migration capabilities of the huaman choriocarcinoma cell line JAR for further elucidating the role of SDF-1/CXCR4 axis in the pathogenesis of preeclampsia.Methods JAR cells were divided into four groups: SDF-1 group (treated with 50 ng/ml of SDF-1),SDF-1+AM3100 mixed group (first treated with 100 ng/ml of AMD3100 for 2 hours and then treated with 50 ng/ml of SDF-1),AMD3100 group (treated with 100 ng/ml of AMD3100) and blank control group (without any treatment).RT-PCR was performed to detect the expression of CXCR4 at mRNA level in JAR cells.Western blot assay was used to measure the expression of CXCR4 and p-AKT at protein level.MTT assay was used to analyze the effects of different concentrations of SDF-1 (10,30,50 and 100 ng/ml) on the proliferation of JAR cells at different time points (0,24,48,72 h).Transwell invasion assay and wound-healing assay were used to test the changes in invasion and migration capabilities of JAR cells after different treatments.Results (1) Results of the RT-PCR showed that the expression of CXCR4 at mRNA level in JAR cells was increased in the SDF-1 group (1.839±0.083) as compared with that in the blank control group (1.372±0.086),AMD3100 group (0.694±0.045) or SDF-1+AM3100 mixed group (0.703±0.093).Moreover,the differences between the SDF-1 group and the other three groups were statistically significant (F=30.67,P<0.05).Compared with the blank control group,the expression of CXCR4 at mRNA level in JAR cells was decreased in the AMD3100 group (P<0.01).(2) Results of the Western blot assay showed that the expression of CXCR4 and p-AKT at protein level in JAR cells were enhanced in the SDF-1 group as compared with that in the blank control group,AMD3100 group or SDF-1+AM3100 mixed group.Compared with the blank control group,the expression of CXCR4 and p-AKT at protein level in JAR cells were inhibited in the AMD3100 group.(3) Results of the MTT assay showed that SDF-1,especially at the concentration of 50 ng/ml,could enhance the proliferation of JAR cells (P<0.05) and its best effect on proliferation was seen at 48 h.(4) Results of the Transwell invasion assay showed that the number of transmembrane cells in the SDF-1 group (70.49±2.42) was more than that in the blank control group (54.36±2.26),AMD3100 group (21.68±8.31),or SDF-1+AMD3100 mixed group (28.18±4.61).The differences between the SDF-1 group and the other three groups were statistically significant (F=116.26,P<0.01).Compared with the blank control group,the number of transmembrane cells was reduced in the AMD3100 group (P<0.05).(5) Results of the wound-healing assay showed that the relative migration distance was increased in the SDF-1 group (1.162±0.034) as compared with that in the blank control group (0.823±0.101),AMD3100 group (0.160±0.047),or SDF-1+AMD3100 mixed group (0.183±0.064).The differences between the SDF-1 group and the other three groups were statistically significant (F=30.500,P<0.05).Compared with the blank control group,the relative migration distance was decreased in the AMD3100 group (P<0.01).Conclusion The invasion and migration of huaman choriocarcinoma JAR cells can be enhanced by SDF-1,but inhibited by AMD3100.This study indicates that the blocked biological axis of SDF-1/CXCR4 may play an important role in the pathogenesis of preeclampsia through inducing abnormal activation of PI3K/AKT pathway,which results in inhibited invasion and migration of trophoblast cells and placenta abnormality.

Objective To discuss the treatment action and mechanism of Wenjing Tongluo Formula on oxaliplatin-induced perpheral neurotoxicity in rats. Methods Intraperitoneal injection was used to inject oxaliplatin 4 mg/kg to establish oxaliplatin-induced peripheral neurotoxicity rat models. Female Wistar rats were randomly divided into normal group, model group, and TCM group. TCM group was given Wenjing Tongluo Formula to soak rats’ limbs and tails. Rats in the model group were soaked with deionized water for comparison. Rats in the normal group received intraperitoneal injection with 5%glucose. Algesia hypersensitivity and anaphylaxis were detected under the mechanical stimulation and temperature. Immunohistochemical method was used to detect the expression of GFAP in L4-L6 spinal dorsal horn of rats. Explore the level of GLT-1 in L4-L6 dorsal root ganglia by RT-PCR. Results Rats in model group showed obvious behavioral changes compared with normal group (P<0.05);Rats in the TCM group improved in behavioristics compared with model group (P<0.01);number of positive cells in GFAP of rats in the model group increased compared with normal group (P<0.05);the increase in the TCM group was not obvious. Compared with normal group, astrocytes in spinal dorsal horn of model group were enlarged, protuberances increased, became coarse, and GLT-1 mRNA is decreased (P<0.05, P<0.01). Compared with model group, active cells and protuberances in the TCM group decreased (P<0.01), GLT-1 mRNA is increased (P<0.01). Conclusion Wenjing Tongluo Formula can improve behavioral changes of model rats under temperature and mechanical stimulation, probably related to harmful signal transmission induced by inhibition of astrocyte in spinal dorsal horn.
