  • 简介:AbstractObjective:To evaluate the efficacy of progestin-primed ovarian stimulation (PPOS) protocol in infertile women with high basal follicle-stimulating hormone (FSH) levels ≥15 IU/L.Methods:Patients with high basal FSH levels ≥15 IU/L with autologous oocytes from September 2016 to March 2019 were reviewed. Either medroxyprogesterone acetate 4 mg/d or clomiphene citrate (CC) 50 mg/d was administered daily from day 3 to the trigger day. When serum FSH levels decreased to ≤15.0 IU/L, a low dose of human menopausal gonadotropin (hMG) 75/150 IU/d was administered to promote late follicular development.Results:Two hundred and twenty women were retrospectively analyzed in this study. Among them, 139 patients were administered with PPOS protocol as the study group, and 81 patients were administered with CC protocol as the control group. The numbers of received oocytes and viable embryos were higher in the study group than those in the control group (1.5 ± 1.2 vs. 1.2 ± 0.8 and 0.8 ± 0.8 vs. 0.5 ± 0.6, respectively, P < 0.05). However, hMG duration and dosage were significantly higher in the study group than those in the control group (4.2 ± 2.7 d vs. 1.1 ± 2.3 d and 609.1 ± 424.5 IU vs. 140.7 ± 231.3 IU, respectively, P < 0.01). Incidence of luteinizing hormone surge and cycle cancellation rate were lower in the study group than those in the control group with statistical difference (2.88% vs. 16.05% and 36.50% vs. 50.63%, respectively, P < 0.05).Conclusions:PPOS protocol can effectively downregulate the endogenous FSH levels. Compared with CC protocol, treatment with PPOS protocol in patients with high basal FSH levels ≥15 IU/L could receive more oocytes and more viable embryos.

  • 简介:Granulocyte巨噬细胞刺激殖民地的因素(GM-CSF)是一个重要造血的生长因素和有免疫力的调节的人。GM-CSF也在各种各样的传播白血球的功能的活动有深刻效果。它被许多房间类型在收到有免疫力的刺激之上包括T房间,巨噬细胞,endothelial房间和成纤维细胞生产。尽管GM-CSF局部地被生产,它能以一种paracrine方式行动到在主人防卫提高他们的功能的成员传播neutrophils,单核白血球和淋巴细胞。最近的集中的调查为它增加树枝状的房间(DC)成熟和功能以及巨噬细胞活动的能力作为一个有免疫力的助手在GM-CSF的应用程序上被集中。在经历化疗的癌症病人对待嗜中性白血球减少症临床上被使用,在在治疗期间的爱滋病病人,并且在在骨髓移植以后的病人。有趣地,GM-CSF-deficient老鼠的造血的系统看起来正常;最重要的变化在一些特定的T房间回答。尽管GM-CSF的分子的克隆用T房间的cDNA图书馆被执行,T房间在激活以后生产GM-CSF,是众所周知的,在T房间功能上有在由T房间和它的效果的生产的这cytokine的系统的调查的缺乏。在这篇文章,我们将在T房间主要集中于GM-CSF的免疫生物学。

  • 简介:AbstractObjective:Various techniques are proposed for changing fetal presentation. We aimed to assess the effect of BL67 point stimulation on correcting breech presentation and natural delivery in women at 36-38 gestational weeks.Methods:A parallel single blinded randomized clinical trial was conducted on 72 eligible pregnant women with breech presentation at the 36 weeks of pregnancy. The subjects were divided into two groups - intervention (n = 36) and control groups (n = 36) by block randomization method. The intervention group stimulated the BL67 point by self-administration for 20 min once a day for 2 weeks. Finally, the appearance of cephalic presentation and rate of vaginal delivery was compared between the groups (n1 = n2 = 32) using the Chi-square test and multivariate logistic regression.Results:The correction of breech to cephalic presentation occurred in 53.1% of patients in the intervention group. The adjusted relative risk (RR) for fetal correction from breech to cephalic was 1.80 (RR = 1.80, 95% confidence interval [CI], 1.13-5.17). It was shown that the stimulation of the BL67 point increased the correction of breech to cephalic presentation. In addition, the rate of vaginal delivery increased by >4-fold (RR = 4.16, 95% CI, 2.54-6.82) by correction to cephalic presentation. Moreover, 65.6% of mothers in intervention group and 90.6% in the control group underwent cesarean section.Conclusions:The stimulation of the BL67 point is a safe, inexpensive, and effective method that can be self-administered at home for fetal correction from breech to cephalic presentation in women with breech presentations during 36-38 gestational weeks. This promotes uncomplicated natural childbirth.

  • 简介:antitumor疫苗的最终的目标是开发记忆CD8+细胞毒素的T淋巴细胞(CTL),它是antitumor免疫的批评调停人。我们以前证明ovalbumin(卵)特定的CD4+T基于房间(OVA-T用搏动卵的树枝状的房间产生的EXO)疫苗(DC卵)-releasedexosomes(EXO卵)经由IL-2和costimulatoryCD80发信号刺激CTL回答。估计另外的costimulatory小径的潜在的参与并且为存储器CTL开发定义costimulation的关键成分,我们首先使免疫野类型(WT)有WTCD4+OVA-TEXO房间或OVA-T有各种各样的分子的缺乏的EXO房间。我们然后估计了卵特定主要并且召回CTL回答使用PE-H-2K由流动cytometry染色的b/OVA257-264tetramer和FITC-anti-CD8抗体。我们也对表示卵的B16黑瘤房间线BL6-10卵。我们表明了那CD4+OVA-TEXO房间与DC卵。由估计主要并且在与OVA-TEXO或与OVA-T缺乏costimulatory分子CD40L,4-1BBL或OX40L的EXO,我们证明这些costimulatory信号为由OVA-TEXO。有趣地,CD40L,然而并非4-1BBL或OX40L,对BL6-10卵肿瘤。总的来说,这个工作建议能够经由CD40L发信号刺激长期的功能的CTL记忆的一支新奇CD4+T基于房间的疫苗可以代表一条新奇、有效途径到antitumor种痘。
