Objective To evaluate the influence of adenomyosis on IVF-ET outcomes in infertile patients with endometriosis.Methods 122 cases were divided into two groups:group A(research group)contained 32 patients in infertile with both adenomyosis and endometriosis;group B(control group) contained 90 patients with endometriosis.The main data measured were response to COH,outcome of IVF-ET.Results Both groups had no significant difference in Gn dosage,number of oocytes obtained,number of fertilization and number of cleavage(all p＞0.05),The clinical pregnancy rate of group A was 21.9%,which was lower than that of group B(30.0%),but there were no statistical difference(P＞0.05).Conclusion Adenomyosis had no adverse effects on IVF-ET outcomes in infertile women with proven endometriosis.

Background:Collagen triple helix repeat containing protein-1(Cthrc1)has been reported playing an important role in liver diseases,especially in liver fibrosis,however,its effect on hepatic stellate cells proliferation is not fully clear. Aims:To investigate the effect of Cthrc1 on proliferation of hepatic stellate cells. Methods:Recombinant adenovirus vector of Cthrc1 was constructed. After injecting Ad-Cthrc1 through tail vein,mRNA and protein expressions of Cthrc1 were determined by real-time PCR and Western blotting,respectively. Liver fibrosis model was established by bile duct ligation and fed with 3,5-diethoxycarbonyl-1,4-dihydrocollidine(DDC)in mice,respectively. The liver fibrosis mice were injected with Ad-Cthrc1 or Ad-GFP through tail vein. Immunofluorescence was used to determine number of hepatic stellate cells. Results:Recombinant Cthrc1-adenovirus vector was successfully constructed. Real-time PCR and Western blotting showed that mRNA and protein expressions of Cthrc1 were increased in Ad-Cthrc1 group than in control group. HE and Masson staining demonstrated that mice model of liver fibrosis was successfully established. Immunofluorescence showed that overexpression of Cthrc1 inhibited significantly the proliferation of hepatic stellate cells. Conclusions:Recombinant adenovirus vector of Ad-Cthrc1 constructed can express stably in vivo,and inhibit the proliferation of hepatic stellate cells. Therefore,Cthrc1 may become a potential target for treatment of liver fibrosis.

We searched and retrieved literature on the topic of medical image processing published on SCI journals in the past 10 years. We then imported the retrieved literature into TDA for data cleanup before data analysis and pro cessing by EXCLE and UCINET to generate tables and figures that could indicate disciplinary correlation and research hotspots from the perspective of bibliometrics. The results indicated that people in Europe and USA were leading researchers on medical image processing with close international cooperation. Many disciplines contributed to the fast development of medical image processing with intense interdisciplinary researches. The papers that we found show recent research hotspots of the algorithm, system, model, image and segmentation in the field of medical image processing. Cluster analysis on key words of high frequency demonstrated complicated clustering relationship.

Objective To investigate the influence of ovarian arterial blood flow index on pregnancy outcomes in patients undergoing in vitro fertilization and embryo transfer (IVF-ET).Methods Totally 136 infertile patients undergoing IVF-ET from February 2014 to April 2016 were divided into pregnant group and non-pregnant group.The monitoring through transvaginal B of two groups for chorionic gonadotropin (HCG) day and ovarian artery resistance index (RI),pulsatility index (PI) and umbilical artery diastolic flow velocity height ratio (S/D) on 2nd day of menstruation (M2) was conducted.The difference of blood flow indexes in two groups was analyzed.Results Compared with those in non-pregnant group,RI,PI and S/D in pregnant group were decreased on M2,and the difference was statistically significant (P ＜ 0.05).RI and PI were also decreased significantly on HCG day,and the difference was statistically significant (P ＜ 0.05),but S/D showed no significant changes (P ＞ 0.05).RI and PI decreased significantly on HCG day in two groups (P ＜ 0.05) when compared with those on M2,but in non-pregnant group,the comparison of S/D on HCG day showed no statistical significance (P ＞ 0.05).Conclusions There is close relationship among RI and PI of ovarian artery and ovarian reserve function.RI and PI are effective indexes to predict outcomes in IVF-ET,and provide scientific basis for the preparation and treatment for IVF-ET.

Background Streptozotocin (STZ)-induced type 1 diabetic model is an acceptable model and is often used to the study of diabetic retinopathy (DR).However,the model is often established using retinal digest preparation in vitro in albino rats,and therefore it is difficult to evaluate the change of retinal vessels by fundus fluorescein angiography (FFA) in vivo.Recently,pigmented rats are being used as the DR model.But the study on the comparison between albino rat model and pigmented rat model is seldom.Objective This study was to observe and compare the manifestations of FFA and retinal digest preparation in early diabetic pigmented diabetic rat and albino diabetic rat,and to select the right model of DR using FFA.Methods Type 1 diabetic models were induced in 15 six-week-old health male BN rats and 15 six-week-old health male SD rats by the injection of STZ (55 mg/kg) via tail vein.The models were thought to be successful in the rats with the blood glucose level ≥ 16.7 mmol/L.The right eyes of the rats were extracted 6 weeks after injection of STZ.Lens were examined by slit lamp microscope.Retinal vascular changes were examined by fundus photography,FFA and periodic acid Schiff staining of retinal digest preparation.The manifestations of FFA and retinal digest preparation were contrasted between BN rats and SD rats.The number of eyes with lens opacification was compared by Chi-square test and the ratio of vascular endothelial cells and perithelial cells (E/P) was compared between BN rats and SD rats.The use and care of experimental animals complied the Statement of Ethic Committee of Tianjin Medicine University.Results Six weeks after injection of STZ,11 BN rats and 10SD rats were included in this study.The blood levels were (24.73±2.98) mmol/L and (22.36±3.65) mmol/L in BN rats and SD rats,respectively,without significant difference between the 2 types of rats (t =7.873,P＞0.05).Lens opacification occurred in 6 BN rats and in 5 SD rats (P=0.717).FFA showed the clear retinal vascular under the brown background.Evident vessel disorder and fluorescence leakage like background stage of DR were seen in 9 eyes.However,in the SD rats,retinal vessel abnormality could not exhibited owing to the interference of choroid fluorescent light from choroidal vessels and vortex vein.Retinal digest preparation exhibited that unevenness of vessel diameter,decrease of perithelial cells and increase of endothelial cells in both types of rats.The E/P values were 11.50±3.68in the BN rats and 12.86±3.94 in the SD rats,without significant difference between them (t=9.785,P＞0.05).Conclusions The abnormality of fundus vascular morphology can be better displayed in pigmented diabetic rats than albino rats by FFA in vivo.

Objective To evaluate the association between recurrent miscarriages and insulin resistance.Methods The case-control studies on the association between recurrent spontaneous abortion and insulin resistance from June 1996 to April 2012 were collected from Medline,Elsevier,Chinese Journal Fulltext Database,Chinese Biological Medicine Database,data base of Wanfang,Springer link and EMBASE.RevMan 5.1 software was used for Meta analysis.Results According to the included criteria,7 clinical trials were finally selected.Total 467 cases with recurrent pregnancy loss were enrolled in study group,while 413 women with no history of abnormal pregnancies were enrolled in control group.No significant difference was found in average age and body mass index between the two groups (P ＞ 0.05).Meta analysis results showed that the level of fasting glucose was no statistical difference between study group and control group (WMD =2.27,95％ CI:-1.11 to 5.65,P ＞0.05); fasting insulin level was higher 2.05 mU/L in study group than that of in control group,the difference was statistically significant (WMD =2.05,95％ CI:1.03 to 3.08,P ＜ 0.01).Case number of study group on Homa-insulin resistance ＞ 4.5 was more than that of control group (OR =3.36,95％ CI:1.72 to 6.57,P ＜ 0.01).Case number of study group on glucose/insulin ratio ＜ 4.5 was more than that of the control group,statistical difference was found (OR =3.37,95％ CI:1.90 to 5.99,P ＜ 0.01).Conclusion Insulin resistance is associated with the susceptibility to recurrent miscarriages,and it may contribute to the occurrence of recurrent miscarriages.

Objective To investigate the influence on developmental potential of frozen-thawed rabbit oocytes with double assisted activation followed by intracytoplasmic sperm injection (ICSI). Methods A total of rabbit oocytes were collected and thawed after vitrification cryopreservation. Among all oocytes were cultured for 1 hour followed by ICSI. 156 Survived oocytes were divided into 5 groups randomly. I0634 single activation: 30 oocytes were added with calcium ionomycin ( I0634 ) at 5 μmol/L for 5 minutes;SrCl2single activation: 26 oocytes were added with strontium chloride at 10 mmol/L for 10 minutes;10634 double activation: 33 oocytes were activated by I0634 twice;SrCl2 double activation: 28 oocytes were activated by strontium chloride twice. Control group: 39 oocytes were not added with any activators. The rate of fertilization, cleavage and blastocysts formation were observed and compared between various groups. Result The rates of fertilization, cleavage and blastocysts formation were in group of SrCl2 single activation were higher than those of I0634 single activation group without statistical difference (54% vs. 33%, 27% vs. 17%, 8% vs. 3%, P <0.05 ). However, those above rates in double activation by I0634 were higher significantly than those of single I0634 activation (82% vs. 33%, 55% vs. 17%, 15% vs. 3%, P < 0.05). The rates of fertilization (61%) was higher and the rate of cleavage (21%) and blastocysts formation (7%) were lower in group of SrCl2 double activation in comparison with group of SrCl2 single activation without reaching statistical difference (P<0.05 ). Notably, the rates of fertilization, cleavage and blastocysts formation in I0634 double activation group were higher than those in group of SrCl2 double activation with statistical difference (82% vs. 61%, 55% vs. 21%, 15% vs. 7%, P<0.05). Conclusion It might enhance the potential of fertilization of oocytes and early embryo development treated by double activation following ICSI, however, those activated oocytes demonstrate rapid cleavage.

0bjectlve To examine the metaphase II spindle and chromosome configurations of human oocytes cultured for different times after thawing.MethodsUsing slow.cooling and raid—thawing protocol combined with 0.3 mol/L sucrose and 1.5 mol/L 1,2-propanedio 1(1,2-PROH)to cryoprotect human mature oocytes(n=102),the 64 survival oocytes without abnormal zona pellucida and cytoskeletal were randomly assigned to three groups after thawing:group A:culture 1 hour(n=20),group B:culture 3 hour(n=22),group C:culture 5 hours(n=22),the flesh oocytes served as control group(n=18).Immunocytochefifical staining and fluorescence microscopy were used to assess the morphology of the metaphase II spindle and chromosome.Results(1)The normal spindle rates of groups A,B and C were 10％(2/20),46％(10/22)and 41％(9/22)respectively,significantly decreased compared with control group(83％,15/18;P<0.05).The rates of absent spindle in group A(45％,9/20)was significantly higher than control group(6％,1/18;P<0.01).Also,the rates of absent spindle in group A was higher than groups B(14％,3/20)and C(14％,3/20;P<0.05).However,no significant differences were observed in groups B and C(P>0.05).(2)A significant increase in abnormal chromosome rate was observed in group A(30％,6/20)compared to groups B(68％,15/22),C(64％,14/22)and control group(78％,14/18;尸<0.05).No differences in chromosome morphology were observed in groups B,C and control group(P>0.05).Conclusions The cryoproteetant protocol leads to a deleterious effect on the organization of the meiotic spindle and chromosome at MI stage.The 3—5 hours post—thawing incubation could permit restoration of the meiotic spindles and chromosome.

Objective To investigate the association between polymorphism of cytochrome P450 subfamily Ⅺ A polypeptide 1 (CYP11A1) gene and polycystic ovarian syndrome (PCOS) in Chinese population. Methods From May 2005 to Dec.2008,290 PCOS cases treated in the First affiliated hospital of Anhui Medical University matched with 344 reproductive women as controls were enrolled in this study. Genotypes of 7 tagging single nucleotide polymorphisms(tSNP,rs12438594,rs4077582,rs9806234,rsl6968477,rs4887139,rs1843090,rsl 1632698)covering CYP11A1 gene (r~2≥0.8) and 3 microsatellite markers (D15S1547,D16S520,D15S1546) were chosed from the phase II database of Han population in HapMap data.Genotype and frequency of allele were detected by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and haplotype of gene polymorphism were analyzed in 290 PCOS cases and 344 controls.Results Among 7 tSNPs and 3 microsatellite markers,the frequency of rs4077582,D15S1547,D15S1546 and rsl 1632698 between two groups reached statistical difference (P =0.010,0.044,0.018 and 0.026).The allele frequency of rs4O77582,rs4887139,rsl843090,D15S1547 and Dl 6S520 showed significant difference between two groups(P=0.002,0.048,0.030,0.001 and 0.024).Among 5 haplotype of CYP11A1(ACGCA13/6/9AG,ACGTA16/6/11AA,GCACG12/8/8AA,GTACA14/4/7GG,GTGCA13/6/7AG),the frequency of GTACA14/4/7GG and ACGCA13/6/9AG were 7.8% (45/580) and 25.3% (147/580) in PCOS group and 11.9% and 19.6% in control group,which showed statistical difference (P< 0.05 ).There was no significant difference in the level of serum androgen at difference genotype from rs4077582 between two groups (P>0.05).Conclusion The polymorphism of CYP11A1 gene was associated with PCOS,however,the relationship between gene sequence covered by tSNP/microsatellite markers and hyperandrogenism of PCOS should be further investigated.
