OBJECTIVETo study the application value of normal sperm morphology on the outcomes of classic in vitro fertilization and embryo transfer (IVF-ET).
METHODSThis study included 659 infertile couples admitted to our center for IVF-ET. Based on the percentage of morphologically normal sperm (MNS), we divided the patients into groups A (n = 112, MNS < 2%), B (n = 180, MNS > or = 2 - < 4%), C (n = 74, MNS > or = 4 - < 5%), and D (n = 293, MNS > or = 5%), and compared the rates of fertilization, normal fertilization, embryos obtained, biochemical pregnancy, clinical pregnancy, implantation, and live birth among different groups.
RESULTSThe mean fertilization rate was significantly higher in groups C (71.90%) and D (72.89%) than in A (57.97%) and B (63.29%) (P < 0.05), with no remarkable differences either between A and B (P > 0.05) or between C and D (P > 0.05). The normal fertilization rate was also significantly higher in group D (57.16%) than in A (46.52%) and B (50.89%) (both P < 0.05) as well as in C (54.67%) than in A (P < 0.05). The rate of embryos obtained, too, was markedly higher in group D (55.62%) than in B (45.75%) (P < 0.05), but none with remarkable difference from other groups (all P > 0.05). There were no statistically significant differences among the four groups in the rates of biochemical pregnancy, clinical pregnancy, implantation, abortion, and live birth (all P > 0.05).
CONCLUSIONThe rate of MNS had some influence on IVF-ET, and 5% MNS exhibited a higher value than 4% MNS in predicting the outcomes of IVF.

OBJECTIVETo investigate the association between CTLA-4 gene polymorphism and Henoch-Schönlein purpura (HSP) in children.
METHODSSixty children who were diagnosed with HSP were enrolled as the case group, consisting of 33 males and 27 females. Thirty healthy children were enrolled as the control group. The patients were further divided into HSP nephritis (HSPN) and non-HSPN groups (n=30 each) according to the presence or absence of nephritis. Polymerase chain reaction-restriction fragment length polymorphism was used to analyze the genotype and allele frequencies at +49 and -1722 loci.
RESULTSAA, AG, and GG genotypes were detected at +49; neither genotype nor allele frequencies showed significant differences between the case and control groups, between the HSPN and non-HSPN groups, and between male and female patients (P>0.05). TT, TC, and CC genotypes were detected at -1722; neither genotype nor allele frequencies showed significant differences between the case and control groups and between male and female patients (P>0.05). There were significant differences in CC genotype frequency and T and C allele frequencies between the HSPN and non-HSPN groups (P<0.05). Combinational analysis of +49 A/G and -1722 T/C showed no significant differences in the genotype frequency between the case and control groups and between male and female patients (P>0.05). GG-CC combination showed a significant difference between the HSPN and non-HSPN groups (P<0.05).
CONCLUSIONSCTLA-4 +49 A/G polymorphism is not associated with HSP. CC genotype and C allele of CTLA-4 -1722 and the combination of GG at +49 A/G and CC at -1722 T/C may be risk factors for HSPN.

Different cytokines are needed in the course of culturing cells to do adoptive immunotherapy. This study was aimed to investigate the differentiation directions of lymphocytes and related gene expression characteristics after combined stimulation of lymphocytes by different cytokines or EBV antigen peptide combined with cytokines. The experiment was divided into 4 groups. The levels of total T lymphocytes (CD3(+)), T helper lymphocytes (CD3(+)CD4(+)), cytotoxic T-lymphocyte (CD3(+)CD8(+)), memory T cells (CD3(+)CD8(+)CD45RO(+)), naive T cells (CD3(+)CD8(+)CD45RA(+)), Th2 cells (CD3(+)CD30(+)), B cells (CD19(+)), NK cells (CD56(+)), naive T regulatory cells (CD4(+)CD25(+)), precise T regulatory cells (CD4(+)CD25(+)FOXP3(+)) were detected by flow cytometry. The expression levels of house-keeping gene (mad1, pten), T helper cells transcriptional regulatory gene t-bet (Th1), gata3 (Th2), cytokine IFN-γ(Th1), IL-4(Th2) were detected by using RT-PCR. The results showed that CTL in EBV polypeptide group were dominant cells with certain clinical effects. Comparison of result of EBV polypeptide group with other 3 different cytokine stimulating groups demonstrated that EBV antigen peptide had much more effects on stimulating CTL generation. The expression of IFN-γ gene was significantly increased; the T helper differentiation-related gene t-bet, gata3 also increased evidently, while expression change of house-keeping gene mad1 and pten were not evident. Addition of different cytokines and antigen peptides in culture may be much more effective on stimulating CTL generation. It is concluded that specific CTL can be obtained by using the lymphocytes co-cultured with EBV and cytokines, and the different cytokines play different roles in cell differentiation.

Objective:
To investigate the prevalence of Ureaplasma urealyticum (UU) infection in infertile men, its influence on routine semen parameters and the distribution of antisperm antibody (AsAb) and its types in infertile patients with UU infection.
METHODS:
We detected the positive rate of UU infection, semen parameters, and the distribution of AsAb and its types in 662 infertile men and 25 normal fertile male controls followed by comparison of the obtained data between the two groups of subjects.
RESULTS:
The positive rate of UU infection was significantly higher in the infertile men than in the normal controls (52.87% [350/662] vs 16.00% [4/25], χ2 = 11.68, P <0.05). The semen volume, sperm count, sperm concentration and percentage of progressively motile sperm were remarkably lower in the UU-positive infertile males than in the control group (P <0.05). No statistically significant difference was observed between the UU-positive and UU-negative groups in the positive rates of total AsAb (43.4% vs 36.5%, χ2 = 3.25, P >0.05) and AsAb IgA, IgM and IgG in the seminal plasma, or in the percentages of serum AsAb IgM (16.9% vs 20.5%, χ2 = 1.22, P >0.05) and IgG (32.7% vs 28.9%, χ2 = 0.99, P >0.05) except in that of serum AsAb IgA (23.6% vs 17.0%, χ2 = 4.03, P <0.05).
CONCLUSIONS
The UU infection rate is high in infertile males, which decreases the semen volume, total sperm count, motile sperm concentration and percentage of progressively motile sperm and increases the positive rate of serum AsAb IgA.
