RESUMO

OBJECTIVE: To evaluate whether intrauterine injection of hCG before embryo transfer can improve IVF-ET outcomes. DESIGN: Meta-analysis. SETTING: Not applicable. PATIENT(S): Infertile women who underwent IVF-ET and received an intrauterine injection of hCG before ET. INTERVENTION(S): Infertile women treated with or without intrauterine hCG injection before ET. MAIN OUTCOME MEASURE(S): The primary outcomes were live birth rate (LBR), ongoing pregnancy rate (OPR), and clinical pregnancy rate (CPR), and the secondary outcomes were implantation rate (IR) and miscarriage rate (MR). Odds ratios with 95% confidence intervals (CIs) and successful ET rates were pooled to determine the effects of hCG on IVF-ET outcomes. RESULT(S): Fifteen randomized controlled trials (RCTs) with a total of 2,763 participants were included. Infertile women in the experimental group (treated with intrauterine hCG injection before ET) exhibited significantly higher LBR (44.89% vs. 29.76%), OPR (48.09% vs. 33.42%), CPR (47.80% vs. 32.78%), and IR (31.64% vs. 22.52%) than those in the control group (intrauterine injection of placebo or no injection). Furthermore, MR was significantly lower (12.45% vs. 18.56%) in the experimental group than in the control group. CONCLUSION(S): The findings of this meta-analysis indicate that intrauterine injection of hCG can improve LBR, OPR, CPR, and IR after IVF-ET cycles. In addition, different timing and dosages of hCG administration may exert different effects on IVT-ET outcomes. Notably, infertile women treated with 500 IU hCG within 15 minutes before ET can achieve optimal IVF-ET outcomes.

RESUMO

A male newborn presented with hypospadias and differential testicular volumes. Short femur length was detected four times during pregnancy, at 23, 31, 32 and 33 weeks, by ultrasonographic examination. Chromosome analysis was performed on peripheral lymphocytes obtained from the infant and his parents. Fluorescent in situ hybridization (FISH), using sex determining region Y (SRY)/DXZ1 and DYZ3 probes, was performed to verify the deletion of the SRY gene (located on Yp11.3 region) and the activation of Y chromosomal centromeres. Single nucleotide polymorphism (SNP)­array comparative genomic hybridization (CGH) was used to detect copy number variations in the infant. The results revealed a ~2.2 Mb mircodeletion on Yp11.32 containing the short stature homeobox (SHOX) gene. According to the above examinations, the abnormal Y chromosome of the patient was identified as a dicentric derivate of the Y chromosome with pseudoinactivation of one of the two centromeres. The karyotype is therefore: 45,X[20]/46,X,idic(Y)(p11.3).ish psu idic(Y)(p11.3) (SRY++, DYZ3++). array Yp11.32 (118,551­2,393,500)x0[26]/46,X,ishY(SRY+, DYZ3+)[4]. The combination of cytogenetic, FISH and SNP­array CGH technologies was beneficial for diagnosing the karyotype accurately, predicting the prognosis, and preparing an effective treatment plan for the patient.

RESUMO

Forkhead box class O (FOXO) transcription factors play a crucial role in longevity across species. Several polymorphisms in FOXO3 were previously reported to be associated with human longevity. However, only one Chinese replication study has been performed so far. To verify the role of FOXO3 in southern Chinese in the Red River Basin, a community-based case-control study was conducted, and seven polymorphisms were genotyped in 1336 participants, followed by a meta-analysis of eight case-control studies that included 5327 longevity cases and 4608 controls. In our case-control study, we found rs2802288*A and rs2802292*G were beneficial to longevity after Bonferroni correction (pallele = 0.005, OR = 1.266; pallele = 0.026, OR = 1.207). In addition, in the longevity group, carriers with rs2802288*A and rs2802292*G presented reduced HbA1c (p = 0.001), and homozygotes of rs2802292*GG presented improved HOMA-IR (p = 0.014). The meta-analysis further revealed the overall contribution of rs2802288*A and rs2802292*G to longevity. However, our stratified analysis revealed that rs2802292*G might act more strongly in Asians than Europeans, for enhancement of longevity. In conclusion, our study provides convincing evidence for a significant association between the rs2802288*A and rs2802292*G gene variants in FOXO3 and human longevity, and adds the Southern Chinese in the Red River Basin to the growing number of human replication populations.

RESUMO

This study aimed to characterize the immunopotentiating effects and immune receptors for Coriolus versicolor mushroom polysaccharides (CVP), a Chinese medicinal fungus that exerts anti-tumor activities by enhancing host immunity. Proliferation assays were used to determine whether CVP could activate splenocytes. Flow cytometry analysis and IgM and IgG detection were used to characterize CVP-binding cells. Immune receptors were analyzed in immunoprecipitation and western blot assays. The downstream signaling pathways were identified by western blotting or immunostaining. CVP significantly stimulated the proliferation of mouse splenocytes. Fluorescence-labeled CVP (fl-CVP) selectively stained mouse B cells, but not T cells. CVP induced the production of IgM and IgG1 with or without exogenous IL-4. Membrane Ig (B cell antigen-receptor, BCR) was identified as a CVP-binding protein in immunoprecipitation and western blot experiments. CVP-induced B cell proliferation could be significantly inhibited by anti-mouse immunoglobulin (Ig) blocking antibody (Fab) or in cells from TLR4-mutant mice (C3H/HeJ). Phosphorylation of ERK-1/2 and p38 MAPK were clearly increased in a time-dependent manner, as was the nuclear translocation of the cytosolic NF-κB p65 subunit after CVP stimulation. Together, we demonstrate that CVP can bind and induce B cell activation using membrane Ig and TLR-4 as potential immune receptors. CVP activates mouse B cells through the MAPK and NF-κB signaling pathways.

RESUMO

BACKGROUND: The I405V polymorphism of the cholesteryl ester transfer protein gene (CETP) has been suggested to be a protective factor conferring longevity in Ashkenazi Jews, although findings in other races are not supportive. This paper describes a case-control study and a meta-analysis conducted to derive a more precise estimation of the association between CETP 405V and longevity. METHODS: We enrolled 1,021 ethnic Han Chinese participants (506 in the longevity group and 515 controls), then performed a meta-analysis that integrated the current study and previously published ones. Pooled odds ratios (OR) were calculated for allele contrasts, dominant and recessive inheritance models to assess the association between CETP 405V and longevity according to the ethnic stratification. RESULTS: Our case-control data indicated that CETP 405V is a longevity risk allele in all genetic models (P additive =0.008; P dominant =0.008, OR(dominant)=0.673; P recessive =0.017, OR(recessive)=0.654) after adjustment for the apolipoprotein E (APOE) ε4 allele, body mass index and high-density lipoprotein cholesterol. A synergy was detected between 405V and APOE ε4 (P=0.001, OR=0.530). Eight studies were eligible for meta-analysis, which confirmed 405V is the risky allele against longevity in all genetic models: allele contrasts (OR=0.81, 95%CI=0.74-0.88), dominant model (OR=0.72, 95%CI=0.64-0.82) and recessive model (OR=0.80, 95%CI=0.67-0.96). After ethnic stratification, 405V remained a risk allele in East Asians but no significant association was found in Europeans or white Americans. CONCLUSION: Our case-control study suggests CETP 405V as a risk allele against longevity in Chinese. The meta-analysis suggests the involvement of CETP 405V is protective in Ashkenazi Jews but is a risk allele against longevity in the East Asian (Chinese) population.
