ObjectiveTo study the influence of EmbryoGlue on the implantation of embryo and pregnancy outcome in vitro fertilization (IVF)-embryo transfer (ET).Methods From August 2010 to January 2011,243 infertile patients in Reproductive Medical Center of Tianjin Medical University General Hospital who underwent IVF or intracytoplasmic sperm injection (ICSI) were divided into two groups,including 129 cases used EmbryoGlue as the embryo transfer medium in experimental group and 114 cases used G-2 as embryo transfer medium in control group.Pregnancy outcome were compared between two groups.Results (1) The female age,IVF/ICSI constituent ratio,previous failure cycles and infertile factors of patients did not show statistical difference between experimental group and control group (P ＞0.05 ).(2) The implantation rate of women in experimental group increased significantly compared with the control group [ 30.4％ ( 85/280 ) vs.18.8％ ( 48/255 ),P ＜ 0.05 ] ; Clinical pregnancy rate increased significantly compared with the control group [48.8％ (63/129) vs.34.2％ (39/114),P ＜0.05] ; Multiple pregnancy rate increased significantly compared with the control group [ 34.9％ (22/63) vs.20.5％(8/39),P ＜ 0.05 ] ; Ectopic pregnancy rate decreased significantly compared with the control group [ 4.8％(3/63) vs.17.9％ ( 7/39 ),P ＜ 0.05 ].ConclusionEmbryoGlue can facilitate embryo implantation in IVF-ET and reduce the occurrence of ectopic pregnancy.

Objective To analyze the reasons of hypoglycemia in patients with diabetic ophthialmopathy,and summarize the corresponding nursing measures in order to reduce the incidence of hypoglycemia in patients with diabetic ophthialmopathy. Methods The reasons for hypoglycemia were analyzed for 43 patients with diabetic ophthalmopathiy in our hospital from January 2009 to November 2011. Results Taking the hunger-cure arbitrarily,no regular diet,no corresponding adjustment for the insulin quantity after stopping taking hormone medicine,and also after the diabetic symptoms relieved,besides,less food-intake caused by high pressure of eyes,vomiting and appetite decreasing after the vitreous body dissection,and the paramedic had no enough cognition for the harm caused by hypoglycemia,combination medication with cardiovascular medicine were the primary reasons for the occurence of hypoglycemia in patients with diabetic ophthalmopathy. Conclusions Many reasons can cause hypoglycemia in patients with diabetic ophthalmopathy,We should strengthen management,propaganda and education,observation of medication and disease condition as well as improve the attention of eye health care workers for hypoglycemia in order to reduce the incidence of hypoglycemia.

Objective To study the effects of oxytocin antagonists-atosiban on pregnancy outcome after thaw embryo transfer (TET).Methods Between Jul.and Dec.2012,a total of 120 women undergoing TET in Reproductive Medical Center,General Hospital of Tianjin Medical University were randomly allocated into atosiban and control group.They were all transferred 2 or 3 top quality embryos at phase of 7-8 cells.Patients in atosiban group were administered by intravenous administration of atosiban before 30 minutes of embryo transfer with a total administered dose of 37.5 mg.In the control group,no special treatment was given before embryo transfer.All patients in 2 groups underwent progesterone luteal support regularly after embryo transfer,then the clinical rate of pregnancy,implantation and early abortion was compared.Results The clinical pregnancy rate per cycle and implantation rate per transfer were 60％(36/60) and 30.0％ (48/160) in the atosiban group,which were higher than 42％ (25/60) and 20.3％ (31/153) in the control group (all P ＜ 0.05).Early abortion rate was 6％ (2/36)in the atosiban group,which was no statistical difference comapring with control group [16％ (4/25),P ＞ 0.05].Conclusion It was suggested that atosiban treatment before embryo transfer can improve the outcome of pregnancy,and increase clinical pregnancy rate and implantation rate after TET.

Objective To investigate the dynamic expression of the 20S proteasome in peripheral blood mononuclear cells (PBMCs) of type 2 diabetic patients without vascular complications. Methods PBMCs were prepared from 30 type 2 diabetic patients and 30 nondiabetic controls. The general indexes including weight, height and blood pressure were recorded. Fasting plasma glucose, fasting plasma insulin and glycosylated hemoglobin were measured. The protein level of the 20S proteasome was measured by Western blotting. The mRNA expression levels of the 20S proteasome β1, β2 and β5 subunits were detected by real-time PCR. Results Compared with that in the nondiabetic controls, the protein level of the 20S proteasome was significantly increased in the diabetic patients and was positively associated with glycosylated hemoglobin. Conclusion Type 2 diabetic patients without vascular complications have an increased 20S proteasome expression, the significance of which needs to be explored by further study.

Objective To explore the effects of vasoactive intestinal peptide (VIP)on the ratio of CD4+CD25+Treg/CD4+T cell and the expression of TGF-β1 in experimental autoimmune encephalomyelitis (EAE)rats. Methods We randomly divided 60 healthy female Wistar rats into normal control group,EAE control group,VIP low-dose group and VIP high-dose group.We used myelin basic protein (MBP)+ complete adjuvant (CFA)to establish EAE model. Since the day of model construction, the low- and high-dose VIP groups received intraperitoneal injection of 4 nmol/kg (0.2 mL)and 16 nmol/kg (0.8 mL)of VIP every other day,respectively;normal control group and EAE group received injection of saline of 0.8 mL for 10 days in a row.We recorded the peak of neurological dysfunction score (NDS)changes in the rats,observed the pathological changes and GFAP+astrocyte activation in the brain at the morbidity peak of rats with HE staining,and detected the ratio of CD4+CD25+Treg/CD4+T in the spleen with FACS and TGF-β1 cytokine level in brain tissue with ELISA.Results The peak nerve dysfunction score was decreased in each VIP dose group.In normal control group,there were decreased inflammatory cell infiltration and decreased number of active astrocytes in the brain tissue.The degree of infiltration of inflammatory cells and astrocyte activation in VIP control groups were significantly lower than those in EAE group.The CD4+CD25+Treg/CD4+T cell ratio of the spleen tissue in each dose VIP treated group rats was higher than that in EAE control group.The cytokine level of TGF-β1 in the brain tissue increased in each VIP dose group in the dose-dependent manner.Conclusion Through up-regulating the ratio of CD4+CD25+Treg/CD4+T cell in the spleen tissue,increasing TGF-β1 content in brain tissue,and inhibiting the infiltration of inflammatory cells and the astrocyte activation,VIP plays an important role in prevention and control of EAE.

Objective To identify the Banna viruses isolated in northwestern part of Yunnan prov-ince in order to make the difference clear between the isolates and other Banna viruses isolated in other parts of Yunnan. Methods Three isolates of Banna vires isolated in 2005 and 2006 were identified by morpholo-gy, RNA-PAGE profile and molecular biologic method. Nueleotide and amino acid sequences of segment 12 of the 3 isolates were sequenced and analyzed. Results Three Banna viruses were isolated from mosquitoes collected in northwestern part of Yunnan during 2005 and 2006. Electron microscopy study showed that they are spherical with a diameter of 70 nm, no envelope but two layers of eapsid. It was found that the genome of the 3 isolates composes of 12 segments presenting band profile of 6-6 in RNA-PAGE. Nueleotide acid se-quence analysis about segment 12 showed that the identity was 99% between the 3 new isolates, 98% and 90% between the 3 isolates and the strains isolated in other parts of Yunnan, China and Indonesia, respec-tively. Phylogenetie analysis based on segment 12 gene showed that 3 new isolates clnstered in the same branch with the viruses isolated in other parts of Yunnan. The same difference of amino acids was found between Banna viruses isolated in China and Indonesia strains in the analysis of segment 12. Conclusion Banna virus strains were firstly isolated from mosquitoes collected in northwestern part of Yunnan province. Nueleotide acid sequence analysis of the 3 new isolates showed higher identity with strains isolated in other parts of Yunnan.

BACKGROUND: Echinococcosis alveolaris were not easily discovered in prophasel Although used various kinds of imaging and immunity test, misdiagnosis rate of echinococcosis alveolaris was still high.OBJECTIVE: To study radioimmunoimaging of ~(131)Ⅰ-labelled anti-alveolar hydatid polyclonal antibody in the rat model with Echinococcus multilocularis in vivo.METHODS: Totally 36 Wistar rats were randomly divided into 3 groups. A group included 12 alveolar echinococcosis rats, B group included 12 normal rats, C group included 12 alveolar echinococcosis rats. Rats in the A and B group were injected intrapedtoneally 1 mL ~(131)Ⅰ-labelled anti-alveolar echinococcosis polyclonal antibodies (37 MBq), those in the C group were injected intraperitoneally I mL ~(131)Ⅰ-(37 MBq). All rats were imaged 24, 48, 72, 96 hours later with ECT to measure region of interest (ROI) of alveolar hydatid. The unit weight radioactive counts per minute of three group rats organs were measured after 96 hours, and the targetto-nontarget (TINT) ratios were calculated in A group rats.RESULTS AND CONCLUSION: In A group rat inoculated right lobe of liver alveolar echinococcosis, radioactive parts of the distribution could be seen. And ROI of alveolar echinococcosis were the highest at 72 hours. After dissection the locations were in line, and it was no significant radioactive liver distdbution in B and C group. Rats were sacrified after 96 hours, in vitro determination of radioactive counts show that A group echinococcus multilocularis was (18.610±3.401)x10~3 cpm/g, which was greater than organs except thyroid and gastric tissues (P ＜ 0.001). The rest of organize T/NT ratios were greater than 1.28 apart from the thyroid and gastric tissues. The difference of unit weight radioactive counts per minute of three group had no obviously significance except the polypide tissues (P ＞ 0.05). This proves that ~(131)Ⅰ-1abelled anti-alveolar echinococcosis polyclonal antibodY successfully combinated with alveolar echinococcosis.

Objective To explore the indications,surgical techniques and clinical effects of laparoscopic splenectomy on patients with portal hypertension. Methods Analysis the clinical data of 32 patients of portal hypertenision with laparoscopic splenectomy and open splenectomy from March 2006 until June 2009. Results The effectiveness of the procedures for portal hypertension was evaluated.Among 16 patients with LS, 2 patients were converted to open surgery. There is no significant difference with operatative time, blood loss and hospital fees between the two groups, the laparoscpy group had the shorter mean hospitalization, fasting and draining time. Conclusions If there are enough preparation preoperation, skillful laparoscopic technique and micromesh manipulation during operation,laparoscopic splenectomy is a minimally invasive and safe technique in the patients with lower-grade to medium varicose veins.

ABSTRACT:Objective To investigate the clinical features of seronegative rheumatoid arthritis (RA)in western China and its outcomes after one-year treatment with disease modifying anti-rheumatoid drugs (DMARDs) so as to provide evidence for effective therapy.Methods We made a retrospective analysis of 240 RA patients treated in our department from May 2013 to June 2014.We compared the 47 seropositive and 25 seronegative RA patients in clinical features,laboratory parameters and outcomes after one-year DMARDs medication.Results The percentage of seronegative RA was 10.4% (25/240).The number of swollen small joints was significantly smaller in seronegative RA group (P<0 .0 1 ).Compared with those in seropositive RA,the level of hemoglobin was lower,the level of platelets was higher,and the level of alkaline phosphatase was lower in seronegative RA (P<0 .0 5 ).The remission rate was higher in seronegative RA group than in seropositive RA group after one-year DMARDs administration (P<0.05).Conclusion Seronegative RA is not rare in clinic.Even though seronegative RA patients often present fewer swollen small joints, it is difficult to distinguish between seronegative and seropositve RA just based on the clinical features.Besides,hematological damage is more severe in some patients with seronegative RA.Only after one-year treatment with DMARDs,the remission rate is higher in seronegative RA patients than in seropositve RA ones.
