Objective To investigate the relationship between serum follicle stimulating hormone (FSH), luteinizing hormone (LH), prolactin (PRL) and clinicopathological features and prognosis of serous ovarian cancer retrospectively. Methods A total of 73 patients with serous ovarian cancer treated in the Department of Obstetrics and Gynecology of Tianjin Medical University General Hospital from January 2000 to December 2015 were included in this study. The relationship between serum FSH, LH, PRL and clinicopathological features was analyzed by Mann-Whitney U method. Kaplan-Meier (K-M) method was used to analyze survival rates of patients with different clinical features. Multivariate Cox proportional hazards regression analysis was used to analyze prognostic factors of serous ovarian cancer patients. Results The mean concentrations of serum FSH and LH were significantly higher in the>50 year-old group than those in the<50 year-old group (P<0.05). The mean concentrations of FSH and LH were significantly higher in menopause group than those in non-menopause group (P<0.05). There were no significant differences in serum levels of FSH and LH in patients with other different clinicopathological features (P>0.05). There was no significant correlation between serum PRL concentration and clinicopathological features (P>0.05). Analysis results showed that poor prognosis of patients was related with high serum levels of FSH (>40.13 IU/L), PRL (>14.96 μg/L) and FIGO stage (Ⅲ+Ⅳ) (P<0.05). There was no significant correlation between serum LH concentration and prognosis (P>0.05). COX regression analysis showed that the serum PRL>14.96 μg/L was risk factor for prognosis of serous ovarian cancer [HR(95%CI): 3.530(1.180-10.557),P=0.024]. Conclusion The serum levels of FSH and LH are significantly increased in postmenopausal women than those in menopause women. The serum level of PRL is correlated with the prognosis of serous ovarian cancer.

ObjectiveTo observe the effect of different extracts ofTangwang Mingmu Granule on hypoxia induced gene expressions in vascular endothelial cells.Methods COCl2 intervention cells were used to copy hypoxia models. Human umbilical vein endothelial cells EA. Hy926 were divided into blank group, hypoxia model group,Tangwang Mingmu Granule group, extract 1 (glycosides and flavonoids) group, extract 2 (orgain acids and polysaccharides) group and extract 3 (alkaloids) group. The changes in gene expressions of VEGF, VEGFR-1, VEGFR-2, ICAM-1 and IL-1α mRNA were detected by semi-quantitative RT-PCR.ResultsThe gene expression levels of VEGF, VEGFR-1, VEGFR-2, ICAM-1 and IL-1α were significantly up-regulated under the hypoxic condition (P<0.05), and the ratio of VEGFR-1/VEGFR-2 was significantly reduced. However,Tangwang Mingmu Granule significantly reversed the expressions of these genes.Conclusion The function intensity of gene expressions weakens in the following sequence:glycosides and flavonoids>alkaloids>organic acids and polysaccharides inTangwang Mingmu Granule.

Objective To observe the preventive and therapeutic effects of the new process extracts ofTangwang Mingmu Granule on rats with diabetic retinopathy.Methods The best preparation process technology of drug extraction was improved and selected based on the traditional water decoction of Chinese medicine. The active ingredient of two processes were detected and compared by HPLC. In vitro and in vivo pharmacodynamic evaluation models were used to evaluate the drug effects and analyze its mechanism. MTT assay was used to analyze the inhibitory effects of extracts in the two processes on EA.hy 926 cell proliferation in vitro. The effects of two extracts on STZ induced rat diabetic microvascular disease and its related factors were observed by retinal slice staining and ELISA.Results Compared with the traditional process, the active ingredients of the extracts were improved by the new technology ofTangwang Mingmu Granule. The preparation process ofTangwang Mingmu Granule could significantly improve the diabetic rat retinal microvascular pathological state, and reduce the protein expression levels of angiogenesis related factors.Conclusion The new preparation process could effectively improve the active ingredients in the herbal extract. The extract of new technology showed a significantly effect on the diabetic rats in retinal microvascular pathology state. The mechanism may be related to the regulation of vascular cell adhesion molecules and inflammatory factors.

Hepatic ischemia reperfusion injury (IRI) is a continuous process of damage of liver cells,which could cause a series of clinic reactions.Early owing to IRI,organ failure reaches 10％,and easily leads to acute and chronic liver transplantation rejection.Therefore,study on the treatment method of IRI is very important.Decreasing the adverse effect of IRI could significantly increase the amount of successful liver transplantation.This paper will explore mainly on the pretreatment methods of IRI.

Objective To observe the mechanism of action of different extracts ofTangwang Mingmu Granules on high glucose induced VEGF and IL-1α gene and protein expressions in vascular endothelial cells.Methods Human umbilical vein endothelial cells EA.hy926 were divided into six groups: blank, high glucose,Tangwang Mingmu Granules, extract 1 (glycoside and flavonoid), extract 2 (organic acid and polysaccharides) and extract 3 (alkaloids) groups. High concentration glucose was used to establish the high glucose model in EA.hy926 cells. The expressions of VEGF and IL-1α mRNA were detected by semi-quantitative RT-PCR. The contents of VEGF and IL-1α protein were tested by ELISA.Results The gene expression and protein levels of VEGF and IL-1α were significantly up-regulated under the high glucose condition (P<0.05). However, the above indicators were significantly reduced after the treatment ofTangwang Mingmu Granules. The activity of different parts ofTangwang Mingmu Granules was as follows: extract 1> extract 3> extract 2.Conclusion The action intensity of glycosides and flavonoids, alkaloids, organic acids and polysaccharides on VEGF and IL-1α expression inTangwang Mingmu Granules weakens in sequence.

Objective To investigate the parental origin for a rare case of complete hydatidiform mole and coexisting fetus and to discuss its diagnosis and differential diagnosis.Methods Tissues from the fetus,mole and placenta were collected and pathology analysis and chromosome analysis were done.The DNA from the fetus,mole and parents' peripheral blood leukocytes was amplified with five short tandem repeat (STR) markers (D4S2460,D18S488,D21S2039,DXS1205 and DYS219) at the same time to confirm the parental source of the hydatidiform.Results (1) Casereport:A 27-year-old woman,gravida 1,para 0,was found high risk for neural tube defects at 20 weeks of gestation.At 24+5 weeks of gestation,ultrasound examination demonstrated a normal fetus,a normal placenta and a huge mass with a multicystic appearance attached to the placenta with an obvious demarcation.The fetus died at 26 weeks of gestation.Serum human chorionic gonadotropin-β(β -hCG) level decreased obviously during the first two weeks after artificial induction,but elevated at the third week,and β-hCG titers fell to normal after 2 courses of chemotherapy.Fetus autopsy showed no structure abnormality.Histopathologic examination of the hydatidiform showed swelling of chorionic villi with hyperplasia of the trophoblast and formation of central cisterns suggesting of a twin pregnancy consisting of a complete hydatidiform mole and coexisting fetus.(2) Genetic analysis:The karyotype analysis of the normal placental villi was 46,XY; the cell cultures of fetal cartilage tissue and hydatidiform were failed.STR analysis showed that the fetus was diploid from biparental source;the mole was androgenetic source.And the mole had locus both from Y and X chromosome of the father,so it was heterozygous.It was suggested that this case was derived from one single oocyte fertilized with three spermatozoas.Conclusions STR analysis could be used to confirm the diagnosis of complete hydatidiform mole and coexisting fetus and to find the pathogenetic rnechanism.

Objective To determine the risk factors of urinary tract infection (UTI) after renal transplantation,so as to provide a theoretical basis of reducing the rate of postoperative UTI effectively.Method Such databases as CNKI,VIP,Wanfang,Pubmed,Embase,Ovid,and EBSCO were searched from January 1995 to December 2015 for collecting the studies about UTI after renal transplantation.The search keywords were renal transplantation,kidney transplantation,urinary tract infection and risk factors.Meta-analysis was performed by using the RevMan 5.2 software.Result Fifteen studies were identified,including 1 236 patients in UTI group and 2 729 patients in the control group (non UTI group).The two groups had no significant differences in recipient age,diabetes mellitus history,peritoneal dialysis,cytomegaovirus infection,acute rejection,usage of MMF,usage of Tacrolimus,usage of CsA and retransplantation.The incidence of UTI after renal transplantation was significantly higher in female patients than male patients (OR:2.69;95％ CI:1.92-3.77;P＜0.000 01).The incidence of UTI of cadaveric renal transplantation was higher than living donor renal transplantation (OR:1.51;95％ CI:1.71-1.95;P=0.002).Using D-J tube for urinary reconstruction significantly increased the incidence of UTI (OR:1.51;95 ％ CI:1.07-2.13;P =0.02).Patients in the UTI group had a significantly longer preoperative dialysis time (WMD:1.48;95％ CI:0.22-2.74;P =0.02).Conclusion The female recipients,cadaveric renal transplantation,using D-J tube and prolonged preoperative dialysis time were factors affecting the risk of UTI.UTI after renal transplantation had no relationship with recipient age,diabetes mellitus history,peritoneal dialysis,cytomegaovirus infection,acute rejection,usage of MMF,Tacrolimus and CsA,and retransplantation.

Objective To further definite the distribution of caudal arteries and veins of rat by anatomical dissection and to deepen the understanding of their physiological functions, and provide a basis for standardization of animal experimental techniques and design of animal models. Methods Eighteen SPF adult SD rats were used in this study. Several techniques were used in combination to study the anatomy and histology of the rat tail blood vessels:paraformaldehyde perfusion through the abdominal aorta was performed for rapid and thorough fixation, blue and red paints were injected to visualize the tail veins and arteries, respectively, arterial microangiography was performed to illustrate the distribution of tail arteries, and the microscopic structure of arteries and veins was verified by histological examination. Results Three longitudinal superficial arterial and venous systems of rat tail were confirmed and a dorsal arterial and venous chain structure was defined, which deeped our knowledge about the distribution of the deep blood vessels. In addition, the caliber of arteries was not corresponding with that of veins, providing a basis of their physiological functions. A bilayer cage connecting structure of the rat tail vasculature was for the first time defined. Conclusions The rich vascular structure of rat tail is described in details in this study. The existence of basal vascular system of rat tail is clarified. A concept of bilayer framework of the rat tail vasculature is proposed, which lays a good foundation for related researches of their physiological functions, and provides a good basis for avoiding major injuries and compensatory responses of hindlimb ischemia during animal experiments.

OBJECTIVETo correlate sperm nucleoprotein transition (SNT) with sperm morphology, DNA damage and embryo development, and assess its value for assisted reproductive technology (ART).

METHODSThe SNT of 437 infertile men underwent ART were assayed, and its correlation with sperm morphology, DNA damage, fertilization rate, normal fertilization rate, cleavage rate, available embryo rate, D3 high quality embryo rate, blastocyst formation rate and high quality blastocyst rate were analyzed.

RESULTSThe normal morphology rate of sperms, DNA damage, fertilization rate, normal fertilization rate, cleavage rate, embryo transfer rate (ETR), D3 high quality embryo rate, blastocyst formation rate (BFR) and high quality blastocyst in normal males (Group A, abnormal rate≤30%, 135 subjects) did not significantly differ from those with an abnormal rate between 30% and 60% (Group B, 170 subjects) (P>0.05). For those with an abnormal rate of above 60% (Group C, 132 subjects), the sperm normal morphology rate, DNA damage, normal fertilization rate, ETR, D3 high quality embryo rate, high quality blastocyst rate were significantly lower compared with Group A (P<0.01), while no significant difference was found in fertilization rate, cleavage rate and BFR between groups A and C (P>0.05).

CONCLUSIONSNT is related with sperm morphology rate, DNA damage and embryo development, and should be assessed before ART.
