OBJECTIVETo investigate the factors influencing the pregnancy outcomes of artificial insemination with donor sperm (AID), improve the pregnancy rate, and evaluate the safety of the offspring.

METHODSWe retrospectively analyzed 7,761 cycles of AID for 5,109 infertile couples performed between July 1, 2005 and June 30, 2013 in the Center of Reproductive Medicine of Shenyang No 204 Hospital, the outcomes of pregnancy, and the incidence of birth defects.

RESULTSTotally, 2 252 clinical pregnancies were achieved by AID, in which the pregnancy rate per cycle was 29. 02% and the cumulative pregnancy rate was 44. 08%. The clinical pregnancy rate was remarkably higher in the females of ≤ 35 years than in those of > 35 years old (30.31% vs 20.18%, P < 0.01), in the women with < 5-year infertility than in those with > 5-year infertility (30.83% vs 28.16%, P < 0.01), and in the patients of the ovarian stimulation group than in those of the natural cycle group (33.22% vs 28.68%, P < 0.01) The clinical pregnancy rate was the highest in the first treatment cycle (29.87%), with statistically significant difference from the fourth cycle (23.61%) (P < 0.05), but not between the other cycles (P > 0.05). There were 28 cases of birth defects in the offspring (1.40%), including 6 cases (21.43%) involving the cardiovascular system, 4 (14.29%) involving the musculoskeletal system, 3 (10.71%) involving the urogenital system, 3 (10.71%) involving the central nervous system, 2 cases (7.14%) of cleft lip and palate, 2 (7.14%) involving the respiratory system, 2 (7.14%) involving the gastrointestinal digestive system, and other anomalies.

CONCLUSIONFemale age, infertility duration, and ovarian stimulation treatment are important factors influencing the clinical pregnancy rate of AID. Artificial insemination with cryopreserved donor sperm does not increase the incidence of birth defects, which is considered as a relatively safe technique of assisted reproduction.

Objective To evaluate the safety and effectiveness of multi-mode interventional therapy for complications occurring after renal transplantation.Methods The clinical data of 26 patients with complications occurring after renal transplantation were retrospectively analyzed.Vascular and non-vascular complications were treated with different interventional techniques,and the curative effects were analyzed.Results Vascular complications were observed in 19 patients and non-vascular complications were seen in 7patients.The technical success rate of interventional therapy was 100％.One week after the treatment,the total creatinine level (SCr) was significantly improved,which decreased from preoperative (372.7±295.5)μmol/L to postoperative (184.3±138.4) μmol/L (P＜0.001).No severe complications occurred.Further analysis indicated that no statistically significant differences in patient's general condition,kidney donor source,anastomosis method existed between vascular intervention group and non-vascular intervention (P＞0.05).However,the onset time of vascular complications was markedly earlier than that of non-vascular complications (1.8± 1.4 months vs.118.3 ±54.4 months),the difference was statistically significant (P＜0.001).During the follow-up period lasting for 4-55 months (mean of 18.6 months),3 patients developed recurrence of complications;interventional therapy had to be carried out in 2 patients and their creatinine level returned to normal after treatment,and transplanted renal artery embolization had to be performed in the other patient as whose pseudoaneurysm became enlarged.Conclusion For the treatment of complications occurring after renal transplantation,interventional therapy is less-invasive,rapidly-effective and safe,this technique can timely and effectively improve the renal function and save the transplanted kidney.

ObjectiveTo investigate whether γδ T cells act as a regulatory factor during respiratory syncytial virus (RSV) infections was responsible for the subsequent changes in asthmatic-type inflammation in allergic mice.MethodsMice were sensitized and challenged with OVA,and infected intranasaly with RSV before or after OVA sensitization.Lung sections were stained with HE for determination of inflammatory reaction.Real-time RT-PCR was used to analyze the expression of cytokine mRNA of γδ T cells in the lung and spleen of tested mice.The number of γδ T cells in the spleen and lung of BALB/c mice was determined by flow cytometry.Adoptive transfer of γδ T cells was performed to identify the role of γδ T cells in allergic asthma.ResultsOVA-sensitized and challenged mice exhibited significantly peribronchial inflammation with larger number of mononuclear cells and granulocytes in the lung tissue sections.RSV infection before OVA-sensitization diminished the grade of inflammatory responses induced by OVA treatment.The expression of IFN-γ mRNA was increased siguificantly in RSV-infected,OVA-sensitized mice.In contrast,the level of IL-4 mRNA was diminished.The number of total γδ T cells as well as activated γδ T cells was decreased in the spleen and lung of OVA-sensitized mice by prior RSV infection.Adoptive transfer of γδ T cells obtained from OVA-sensitized and challenged mice induced a slight inflammation in the lung of normal mice,and enhanced inflammatory responses in RSV-infected OVA-sensitized mice.Conclusionγδ T cells may play an important role in the development of allergen-induced allergic airway inflammation.

AIM:To be one of the primary cause injury to multiple sites of ocular of glaucoma which affects over 70 million people worldwide. We applied data mining techniques, linear and the matrix operations, efficiently calculated the network and estimated the possible function of the“node” genes of the retina and optic of glaucoma, in order to provide new thought and method on the pathogenesis of glaucoma.
METHODS: The data in this study is from Gene Expression Omnibus ( GEO ) which belong to Nation Center for Biotechnology Information ( NCBI) , the quality of the raw data CEL files was processed and analyzed by the Expression software which belong to Affymetrix Inc. , Santa Clare, CA, USA. Significant analysis method ( SAM) which base on the T test was used to identified the significant genes. Based on GRNInfer and Gvedit soft we set up gene networks of optic and retina of mice and further more enriched analysis which based on DAVID and MAS3. 0 online software were processed.
RESULTS:The analysis between the group of the optic nerve heads and retinas in different stage of glaucoma showed that the amount of significant different expressed genes in the optic never head group increased significantly comparing with the group of retina in the early stage of glaucoma, the analysis of the genes network construction show that:the node genes of optic nerve heads included Unc13c、Kif5a、TRPM1、PANX; and the node genes of retina include POU4F1, NEFL, BC03870, CALB2. Metabolic pathways enrichment analysis which based on MAS3. 0 online platform show that there was mainly the amyotrophic lateral sclerosis, tyrosine metabolism, melanogenesis, Nitrogen metabolism, Gap junction, Leukocyte transendothelial migration metabolism pathway enriched out in optic nerve head; and there was mainly amyotrophic lateral sclerosis, neurodegenerative disorders, prostate cancer, leukocyte transendothelial migration metabolism pathway enriched out in retina.
CONCLUSION:By understanding bioinformatics result, it seems optic were more sensitive than the retina to high intraocular pressure, and weather high expression of TYrp1 gene can be as a sensitive diagnostic item require more evidence back up. Functional enrich analysis of node gene showed that cytoskeleton reconstructed, molecular motor and nutrients transport function improve in optic; and in retina, the most prominent finding in retina was enrichment function modules were focus on regeneration, repairing and differentiation of cells, which remind that we should reinforce research on reparation of retina of primary glaucoma. Metabolic pathways enrichment analysis show that inflammatory response plays prominent place in optic and retina of primary glaucoma, because of the optic narrow and crowed anatomic shape, nutrient metabolism and substances transfer enrichment modules play an important role in optics of primary glaucoma.
