The in vitro modulation effect of insulin on DNA and IL-2 production of spleen lymphocytes in diabetic mice were studied. The results suggest that the DNA and IL-2 production of the lymphoc-ytes are significantly inhibited in the mice. When suspend the lymphocytes to the culture medium containing insulin, the DNA and IL -2 production of the lymphocytes are remarkably increased. Therefore, insulin is an important immunoregulation hormone.

Objective To compare the outcomes in pregnancy between the patients with poor ovarian reservation receiving ultra-long-term down-regulation protocol and modified long-term protocol who were undergoing in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI),aiming at screening an optimal ovulation induction scheme.Methods Retrospectively analyzed the clinical data of 78 patients with poor ovarian reservation who underwent IVF or ICSI from October 2010 to July 2012.Forty-three patients received modified long-term protocol treatment (group A),with 0.375 mg long-acting triptorelin during the midluteal phase as well as superovulation start date plus alarelin (0.15 mg/d) to intramuscular injection of human chorionic gonadotropin (HCG) day.Thirty-five patients received ultra-long-term down-regulation protocol (group B).Triptorelin was injected intramuscularly in mid-luteal phase twice followed by triptorelin at a dose of 1.2-1.3 mg after 28 days of long-acting triptorehn treatment (1.5 mg).Gonadotropin was started 16 days after the second GnRHa injection.The dose of Gn,number of oocytes retrieved,number of embryos available,implantation rate,pregnancy rate,and miscarriage rate were recorded and compared between the two groups.Results There was no significant difference between the two groups in the mean age of participants,basal follicular number,FSH,the dose of Gn used,number of oocytes retrieved,number of embryos available,number of implanted embryos,Pregnancy rate(32.56％ vs.34.29％),implantation rate(18.75％ vs.20.97％) and miscarriage rate (0 vs.8.33％)(P ＞ 0.05).Conclusion No significant difference was found between the two groups in clinical pregnancy rate and abortion rate.But modified long-term protocol needs a shorter treatment period than the ultra-long-term protocol.Moreover,it reduces the risk of excessive suppression of pituitary function.Therefore,it takes advantages over the other in the clinical application.

Objective To investigate the change of CNP (C-natriuretic peptides) in patients with PCOS (polycystic ovary syndrome) undergoing in vitro fertilization-embryo transfer (IVF-ET) with GnRH-α longprotocol for controll ovarian hyper-stimulation(COH).Methods From March 2012 to September 2014,22cases patients with PCOS undergoing IVF-ET in the Reproductive Medical Center of the Center Hospital of JiangMen were selected as study group(Group 1),and 32 cases patients with normal ovarian reserve,the age younger than 35,and the number of oocytes retrieved more than 6 at the same period were selected as control group(Group 2).The level of serum CNP and estradiol(E2) on the day of human chorionic gonadotropin (HCG) and retrieving oocytes,the level of CNP and E2 in follicular fluid were analyzed.In additional,the levels of CNP and E2 in follicular fluid of different fertility and embryo quality were compared.Results (1) CNP and E2 on the day of HCG were significantly higher than that on the day of retrieving oocytes (CNPof Group 1:(107.21±78.55) μg/L vs.(73.01±55.99) μg/L,CNP of Group 2:(69.16±32.39) μg/L vs.(44.11±27.23) μg/L;E2 of group 1:(5231.38±1489.00) ng/L vs.(1985.52±662.54) ng/L,E2 of Group 2:(3678.45±969.57) ng/L vs.(1567.71±493.93) ng/L;t =2.968,2.752,8.147,14.567;P＜0.05).CNP and E2 on the day of retrieving oocytes and E2 on the day of HCG of Group 1 were higher than that of Group 2(t=2.866,2.227,2.173;P＜0.05).CNP in follicular fluid in Group 1 was higher than that in Group 2,but E2 of in follicular fluid in Group 1 was lower than that in Group 2 (t =2.244,-2.650;P＜0.05).(2) In Group 1,CNP and E2 in follicular fluid of normal fertility were lower than that of unnormal fertility,and E2 in follicular fluid of unnormal fertility were higher than that of no-fertility,and there were significant differences(t =-6.117,-2.374,2.760;P＜0.05).(3) In Group 2,only E2 in follicular fluid of unnormal fertility were higher than that of no-fertility,and there was significant difference(t=2.658,P＜0.05).(4) In 2 groups,CNP in follicular fluid of high-quality embryo were lower than that of non-high-quality embryo,and there was significant difference (t =-2.910,-2.029;P＜0.05).CNP in follicular fluid of non-high-quality embryo in Group 1 were higher than that in Group 2,but E2 in follicular fluid of non-high-quality embryo in Group 2 were higher than that in Group 1,and there were significant differences (t =2.141,-2.009;P ＜ 0.05).Conclusion There are differences in the change of CNP in the patients with PCOS and non-PCOS,and there are some deficiencies of the first meiosis in the patients with PCOS.

Objective To study the effect of self-efficacy on learning effect of medical students.Methods Self-efficacy scores of the questionnaire to clinical medical students who practice in our hospital from September 2012 to April 2013 were measured.Students with score lower than the average were recruited into group A,and the others were recruited into group B.Then the scores of both-group students in the process of clinical practice,the theoretical knowledge,and triguaiacyl tests were gotten for statistical analysis.Results Group B (88.02 ± 3.902; 89.02 ± 3.902; 89.94 ± 3.794) were significantly better than group A (67.07 ± 5.131,66.02± 5.866,65.23 ±6.741) in the scores of the theory of knowledge,operation skills and triguaiacyl test.The correlation analysis showed that self-efficacy was positively related to these three aspects (P=0.032,0.024,0.001).Conclusion Clinical teachers should consciously improve students' self-efficacy in the process of their clinical practice,in order to improve the learning effect of the clinical medical students preferably.

We used a meq-deleted attenuated MDV-I strain GX0101Δmeq as a vector to construct a recombinant virus expressing the exogenous gene NDV-F. The ORF of exogenous gene NDV-F was inserted into the eukaryotic expression vector pcDNA3.1(-). Then, the expression cassette of NDV-F which contains the CMV promoter was amplified. Simultaneously, we amplified the selected gene Kan+ expression cassette and inserted them into the PMD18-T vector. Tandem expression cassettes were amplified using primers containing the 50-bp homologous arm of MDV-US2. The PCR product was electroporated into EL250 host bacteria containing GX0101Δmeq. Then, the Kan+ expression cassette was deleted from the recombinant virus genome using 1% arabinose. The plasmid of the positive clone which the Kan+ expression cassette was deleted was extracted and transfected into CEFs to rescue the recombinant virus. The recombinant virus was injected into chickens to observe its growth and replication. The recombinant virus rMDV-F containing the exogenous gene NDV-F was rescued successfully. The recombinant virus could duplicate and express well in CEFs, and grow and replicate well in chickens. Using GX0101Δmeq as a vector, combined with a recombinant system of Red E/T and FLP/FRT, we constructed a recombinant virus that expressed the exogenous gene NDV-F. This study could lay the foundation for further study of recombinant viruses.

Objective To establish the universal antibody against all subtypes of the influenza A viral hemagglutinins(HA). Methods All HA sequences from influenza viruses in common domains were analyzed to search for the most conservative re,on of the HA gene. The peptides conjugated to carrier proteins were used to immunize rabbits in order to obtain high titer antibody. Results The most conservative region among all influenza viruses HA genes were 14 amino acids located at the N-terminal of HA2. The antibody titer reached to 1 : 80 000 after 4 injections of the coupled peptides. The achieved antibody was demonstrated by Western blot to bind HA proteins of influenza virus subtypes H1-H13 specifically. Conclusion The universal antibody has been successfully established by immunizing the rabbits with most conservative peptides of HA protein coupled to carrier protein.
