The effect of G-CSF on infertile women undergoing IVF treatment: A meta-analysis

Evidence for the effect of granulocyte colony stimulating factor (G-CSF) on infertile women undergoing in vitro fertilization (IVF) remains inconsistent. This study aimed to evaluate the effectiveness of G-CSF on infertile women undergoing IVF. PubMed and EMBASE databases were searched before August 2016. Comparing the transvaginal perfusion of G-CSF and placebo or no treatment, the available studies were considered. The pooled risk ratio (RR) with 95% confidence intervals (CIs) was used in the analysis and six studies were included. Transvaginal perfusion of G-CSF was significantly associated with a higher clinical pregnancy rate versus the placebo (RR=1.563, 95%CI: 1.122, 2.176), especially for the Asian population. Among patients with a thin endometrium or repeated IVF failure, the implantation and biochemical pregnancy rates were also significantly increased in patients with the use of G-CSF (implantation rate: RR = 1.887, 95% CI: 1.256, 2.833; biochemical pregnancy rate: RR = 2.385, 95% CI: 1.414, 4.023). However, no statistical significance in increasing endometrial thickness was detected. Transvaginal perfusion of G-CSF for infertile women may play a critical role in assisting human reproduction, especially for patients with a thin endometrium or repeated IVF failure in the Asian population.

宫腔内灌注粒细胞集落刺激因子联合低分子肝素在薄型子宫内膜患者冻融胚胎移植周期中的研究

目的:探讨宫腔内灌注粒细胞集落刺激因子(G-CSF)联合低分子肝素(LMWH)对薄型子宫内膜患者冻融胚胎移植(FET)周期中的临床疗效。方法:选取2018年6月-2019年10月于山西医科大学第一医院进行FET助孕治疗的薄型子宫内膜患者175例,根据患者自身意愿分为3组,A组:63例患者仅接受激素替代治疗;B组:52例患者接受激素替代治疗+宫腔内G-CSF灌注;C组:60例患者接受激素替代治疗+宫腔内G-CSF灌注+皮下注射LMWH。对3组患者的子宫内膜厚度、子宫内膜血流阻力指数(RI)、搏动指数(PI)、周期取消率、胚胎种植率、临床妊娠率、早期流产率、异位妊娠率等指标进行比较。结果:在内膜转化日,与A组相比,B、C组子宫内膜厚度、Ⅱ+Ⅲ型血流比例均增加,RI、PI均降低(P<0.05)。治疗结局方面,与A组相比,B、C组胚胎种植率、临床妊娠率增加,周期取消率降低,差异有统计学意义(P<0.05);B、C组间比较差异无统计学意义(P>0.05);C组早期流产率较B组降低,差异有统计学意义(P<0.05)。结论:在FET周期中宫腔内灌注G-CSF可提高薄型子宫内膜患者的子宫内膜厚度,改善子宫内膜的血流情况,提高胚胎种植率及临床妊娠率,注射LMWH可降低早期流产率。     

GnRH拮抗剂方案新鲜移植周期临床妊娠结局的影响因素分析

目的：探讨影响促性腺激素释放激素（gonadotropin releasing hormone,GnRH）拮抗剂方案临床妊娠结局的相关因素。方法：回顾性分析2017年1月—2022年3月于安徽省妇幼保健院生殖医学中心采用GnRH拮抗剂方案行体外受精/卵细胞质内单精子注射-胚胎移植（in vitro fertilization/intracytoplasmic sperm injection-embryo transfer,IVF/ICSI-ET）新鲜胚胎移植的262个治疗周期的临床资料,根据是否获得临床妊娠将其分为妊娠组与未妊娠组。采用Logistic回归分析及受试者工作特征曲线（receiver operating characteristic curve,ROC曲线）分析影响临床妊娠结局的相关因素,并计算最佳截断值。结果：人绒毛膜促性腺激素（human chorionic gonadotropin,hCG）日子宫内膜厚度是临床妊娠结局的保护因素（OR=1.421,P<0.001）,子宫内膜厚度的最佳截断值为11 mm,其ROC曲线下面积为0.702;x<9 mm组种植率最低;11 mm<x<15 mm组的临床妊娠率显著高于x<9 mm组和9 mm≤x≤11 mm组（均P<0.05）,但与15 mm≤x<20 mm组比较差异无统计学意义（P>0.05）;各组流产率比较差异无统计学意义（P>0.05）;hCG日A型内膜较B/C型内膜有更好的临床妊娠结局（OR=3.425,P=0.006）。结论：hCG日子宫内膜厚度大于11 mm的A型子宫内膜是GnRH拮抗剂方案新鲜周期临床妊娠结局的保护因素。hCG日子宫内膜过厚或过薄都应引起关注。     

The reproductive outcome of women with hypogonadotropic hypogonadism undergoing in vitro fertilization

Abstract

The aim of this study was to evaluate the reproductive outcome and assisted reproductive technology (ART) outcomes of patients with hypogonadotropic hypogonadism (HH) and to compare the results with male factor (MF) infertility patients. The reproductive outcome of 33 HH patients was evaluated retrospectively and compared with results of 47 patients with mild male factor infertility. For ovulation induction, human menopausal gonadotropin (hMG) was used in HH patients and recFSH was used in MF infertility patients. HH patients were divided into subgroups according to retrieved oocyte numbers and the groups were compared with each other. The main outcome measures were total gonadotropin dose used, duration of stimulation, human chorionic gonadotropin (hCG) day estradiol level and endometrial thickness, oocyte number retrieved, and rate of clinical pregnancy. ART outcomes and cycle characteristics of 33 HH patients were compared with 47 MF infertility patients. There was no difference in age and body mass index (BMI) between the groups, but mean follicle stimulating hormone FSH and luteinizing hormone LH levels were significantly lower in the HH group (p?<?0.001). Duration of stimulation was 12.5?±?2.06 days in the HH patients and 10.08?±?1.62 days in the MF infertility patients and the difference was significant (p?<?0.001). Total gonadotropin dose used was higher in the HH group than the MF infertility group (p < 0.001). However, there were no differences in hCG day estradiol levels, endometrial thickness on hCG day, total oocyte number retrieved, MII oocyte number, and pregnancy rate. In the HH subgroups, patient ages were significantly lower in the >15 oocyte retrieved group. Although patients with HH have a long-term estrogen deficiency, their response to controlled ovarian hyperstimulation treatment is similar to normal women. However, the HH group is heterogeneous and estimating the ovarian reserve before treatment is not always possible in this group.

Effects of granulocyte-colony stimulating factor on cardiac remodeling after myocardial infarction

BACKGROUND: Recent studies suggest that granulocyte colony-stimulating factor (G-CSF) may be beneficial in the treatment of myocardial infarction (MI). However, the effects of G-CSF on MI are still controversial and the molecular mechanism of G-CSF treatment for repair of the infarcted heart is not fully understood. METHODS: Mice were divided into three groups: Control, MI and MI treated with G-CSF. Four weeks after MI, we examined cardiac function by Doppler echocardiography and measured non-infarcted myocardial mRNA expression by northern blot analysis. RESULTS: Cardiac function decreased significantly in the MI groups compared with the sham-operated groups. Additionally, the ratios of E wave to A wave peak velocity (E/A) in the MI groups were higher than in the control group. E/A in G-CSF MI mice was significantly lower than in control MI mice (p<0.01). Matrix metalloproteinase-2 (MMP-2) mRNA expression was significantly increased in the MI groups compared with the control group (p<0.01). Furthermore, mRNA expression in the G-CSF MI group was significantly higher than in the Control MI group (p<0.05). CONCLUSIONS: G-CSF can prevent the LV remodeling process after MI that accompanies progressive cardiac dysfunction. One of the mechanisms of G-CSF treatment for cardiac remodeling after MI may be overexpression of MMP-2 in non-infarcted myocardium.     

经阴道彩色多普勒超声在IVF-ET中对子宫内膜容受性的评估价值

目的:探讨经阴道彩色多普勒超声(TVCD)检测子宫动脉血流动力学、内膜厚度及形态变化能否评估移植前子宫内膜容受性。方法:回顾性分析119个体外受精一胚胎移植(IVF-ET)周期,TVCD检测注射绒毛膜促性腺激素(hCG)日和取卵日子宫动脉血流的搏动指数(PI)和阻力指数(RI)、子宫内膜厚度和形态,分析各个参数变化与临床妊娠的关系。结果:119个IVF-ET周期,临床妊娠率为33.61%(40/119)。妊娠组在hCG日PI和RI显著低于非妊娠组,取卵日妊娠组PI显著低于非妊娠组,RI无差异,hCG日妊娠组内膜厚度显著大于非妊娠组,内膜厚度<8mm者无一例妊娠,妊娠组内膜形态以多层为主。结论:hCG日子宫动脉PI和RI越低,血管阻力也越低,子宫血流灌注良好,获得妊娠机会较大,8mm以上多层内膜适宜胚胎着床,即TVCD对评估子宫内膜容受性有重要意义。     

阴道超声测量绝经前妇女子宫内膜厚度诊断子宫内膜病变

目的:探讨阴道超声测量子宫内膜厚度是否可用于预测绝经前妇女子宫内膜病变。方法:对87例绝经前不规则子宫出血患者行阴道超声测量子宫内膜厚度并于检查当日或次日行分段诊刮术,将阴道超声检查结果与诊刮获取的子宫内膜组织病理结果进行比较。结果:阴道超声测得子宫内膜癌及癌前病变组的内膜平均厚度为(27.3±11.0)mm,子宫内膜良性病变组的内膜平均厚度为(15.5±4.8)mm,均明显大于子宫内膜生理改变组的内膜平均厚度(9.8±4.3)mm,差异均有极显著性意义(P<0.0001)。以10mm为临界值阴道超声预测绝经前妇女子宫内膜病变的敏感性、特异性、阳性预测值、阴性预测值分别为95.9％、57.9％、74.6％和91.7％。结论:阴道超声测量子宫内膜厚度以10mm为临界值可以预测绝经前妇女子宫内膜病变。

目的:探讨体外受精-胚胎移植(IVF-ET)周期中hCG应用的最佳时机。方法:回顾分析75个IVF-ET临床妊娠周期(其中常规IVF37个周期,ICSI38个周期)hCG应用日的基础体温(BBT)、子宫内膜厚度与超声声像类型、优势卵泡最大直径、血清E2水平与宫颈评分。结果:当优势卵泡最大直径达18-20mm和子宫内膜厚度达9-13mm,而超声声像类型呈三线征时,当天是hCG应用的最佳时机;hCG应用日血清E2水平、宫颈评分、BBT与妊娠率密切相关。结论:阴道B超监测子宫内膜与优势卵泡发育是确定hCG应用时机的重要指标,血清E2水平、官颈评分、BBT对于确定hCG应用时机有辅助作用,对评估妊娠机会均有重要意义。     

Perceived risks and reasons to smoke cigarettes during pregnancy among Alaska native women

Objective: The purpose of this study was to explore perceptions of the risks of smoking and reasons Alaska Native women give for smoking during pregnancy.

Design: A total of 118 women (54 smokers, 64 non-smokers) enrolled in a biomarker study and completed a baseline interview asking about their concerns regarding tobacco use while pregnant and reasons why pregnant women might smoke during pregnancy. Responses were collapsed into six categories of perceived risks of smoking and eight categories of reasons to smoke during pregnancy.

Results: The majority of both pregnant non-smokers and smokers (72.6% and 60.4%) agreed that smoking during pregnancy could negatively impact the health of their baby. However, non-smokers were more likely than smokers (77.4% vs. 58.5%) to view smoking during pregnancy as a risk factor for the baby’s development (p?=?.029). Both non-smokers and smokers identified addiction as a reason for smoking during pregnancy (82.8% and 63%); however, non-smokers were more likely than smokers to state this was a reason for use (p?=?.015). Seventy-three percent of the entire sample reported a reason to smoke in pregnancy was to help manage negative affect.

Conclusion: Results from this work may be helpful in advancing research by identifying targets for intervention specific to Alaska Native women receiving prenatal care in Anchorage, Alaska.     

体外受精-胚胎移植术移植日子宫内膜容受性的超声学研究

目的:探讨体外受精-胚胎移植(IVF-ET)/卵泡浆内单精子显微注射(ICSI)周期胚胎移植日胚胎种植率的影响因素。方法:将实施IVF/ICSI的112个周期根据助孕结局分为妊娠组和非妊娠组,比较两组的E2、P、E2/P及子宫内膜厚度/形态、宫腔深度,并与自然周期模拟移植日子宫内膜厚度/形态、宫腔深度进行自身对照研究。结果:两组超排卵周期胚胎移植日宫腔深度、内膜厚度均显著高于自然周期模拟移植日(P0.001);两组胚胎移植日C型内膜的比率均高于模拟移植日(P0.05),而妊娠组与非妊娠组之间宫腔深度、内膜厚度、C型内膜比率无统计学意义;妊娠组E2、E2/P显著低于非妊娠组(P0.05)。结论:超排卵治疗改变了子宫容积和内膜形态,通过生殖激素的变化而影响IVF/ICSI的妊娠结局。     

克罗米芬与GnRH拮抗剂两种温和刺激方案新鲜胚胎移植的治疗结局分析

目的:比较克罗米芬与GnRH拮抗剂两种温和刺激方案中新鲜胚胎移植的治疗结局,探讨克罗米芬温和刺激方案新鲜胚胎移植的选择策略。方法:回顾性分析本院341例接受体外授精-胚胎移植(IVF-ET)治疗的患者资料,其中应用克罗米芬温和刺激方案187例和应用GnRH拮抗剂温和刺激方案154例,比较两组IVF治疗结局,并比较克罗米芬温和刺激方案中,移植日不同子宫内膜厚度患者的治疗结局。结果:克罗米芬温和刺激方案组的Gn使用总量低于拮抗剂温和刺激组,移植日内膜厚度小于拮抗剂温和刺激方案组(均P0.05),但两组的年龄、BMI,基础促卵泡生成激素(FSH)、窦卵泡数(AFC)、Gn使用天数、获卵数、受精率、有效胚胎数、优胚率、移植胚胎数、种植率、临床妊娠率、继续妊娠率等未见统计学差异(P0.05)。克罗米芬温和刺激方案组中的种植率、临床妊娠率、继续妊娠率等随着移植日子宫内膜厚度的增加而增加,将内膜厚度分为9mm及≥9mm两组发现,种植率、临床妊娠率及继续妊娠率等均有统计学差异(均P0.05)。结论:克罗米芬温和刺激方案中选择新鲜胚胎移植可获得与拮抗剂温和刺激方案相似的治疗结局,当移植日子宫内膜厚度达到7mm时可选择新鲜胚胎移植,当厚度≥9mm时选择新鲜胚胎移植更为稳妥。且该方案减少了药物用量成本。     

种植窗期子宫内膜类型和白血病抑制因子的关系

目的:研究种植窗期子宫内膜类型和白血病抑制因子(LIF)的关系。方法:对94例不孕患者于排卵后7~9天行B超测量子宫内膜的厚度、宫腔镜观察子宫内膜血管网及腺体的形态分布、酶连免疫吸附实验测定宫腔冲洗液中LIF浓度。结果:Ⅰ组(腺体开口小或内膜血管呈点状或片状分布)不孕患者的平均年龄高于Ⅱ组(腺体开口大、极度扩张呈指环状,且内膜血管呈网状分布)(P<0.01),不孕年限无差异(P>0.05);原发不孕和继发不孕患者子宫内膜类型无差异(P>0.05);Ⅰ组和Ⅱ组患者的子宫内膜厚度无差异(P>0.05);Ⅰ组宫腔冲洗液中LIF浓度为(15.367±16.285)pg/ml,Ⅱ组中LIF浓度为(71.583±54.233)pg/ml,高于Ⅰ组(P<0.01)。结论:种植窗期子宫内膜类型与不孕患者的年龄及宫腔液中LIF含量有关,推测可能内膜发育差的不孕患者子宫内膜上LIF基因表达发生变异,不能分泌正常量的LIF蛋白,导致子宫内膜腺体和血管网发育不良,胚胎到达宫腔内无法着床或早期流产,这可能是影响种植窗期子宫内膜发育的分子生物学基础之一。     

Malnourished mice display an impaired hematologic response to granulocyte colony-stimulating factor administration

The aim of this study was to determine if protein-energy malnutrition could affect the hematologic response to granulocyte colony-stimulating factor (G-CSF). Swiss mice were fed a low-protein diet containing 4% protein, whereas control mice were fed a 20% protein-containing diet. After the malnourished group lost 20% of their original body weight, the mice were subdivided in 2 treatment groups, and hematopoietic parameters were studied. Mice were injected with either 8 μg/kg per day of G-CSF or saline twice daily for 4 days. Malnourished mice developed anemia with reticulopenia and leukopenia with depletion of granulocytes and lymphocytes. Both malnourished and control mice treated with G-CSF showed a significant increase in neutrophils; however, in the control group, this increase was more pronounced compared to the malnourished group (4.5-fold and 3.4-fold, respectively). Granulocyte colony-stimulating factor administration increased bone marrow blastic (P < .001) and granulocytic (P < .01) compartments in the controls but had no significant effect on these hematopoietic compartments in the malnourished animals (P = .08 and P = .62, respectively). We report that malnourished mice display an impaired response to G-CSF, which contributes to the decreased production of leukocytes in protein-energy malnutrition.

目的 分析农药暴露情况与不良妊娠结局之间的关系。方法 采用免费孕前优生健康检查项目2010年1月至2012年12月的数据进行统计分析。来自全国的248 501对计划在半年内怀孕的夫妻被纳入研究。通过问卷调查收集了夫妻怀孕前的农药接触情况以及妻子怀孕后的农药接触情况。妊娠结局通过医生填写记录。结果 248 501对参与夫妻中,有243 362对夫妻完成全部随访有妊娠结局且没有因为主观因素或意外导致流产或引产等,其中1 806位（0.74%）妻子在怀孕前有农药接触史,2 653位（1.09%）丈夫在妻子怀孕前有农药接触史,505位（0.21%）妻子在怀孕后接触过农药。母亲孕前农药接触是死胎死产（OR=3.37,95% CI：2.05～5.55）、异位妊娠（OR=3.17,95% CI：1.18～8.55）、低出生体重（OR=7.56, 95% CI：5.36～10.66）的危险因素。父亲单独农药接触与自然流产（OR=1.37,95% CI：1.03～1.80）显著相关,在父亲母亲均接触农药与低出生体重正相关（OR=3.65,95% CI：1.51～8.84）,巨大儿负相关（OR=0.64,95% CI：0.44～0.93）。妊娠后农药接触是自然流产（OR=4.65,95% CI：3.47～6.24）的危险因素。其他不良妊娠结局包括早产、巨大儿等。结论 农药接触是死胎死产、异位妊娠、低出生体重、自然流产等不良出生结局的危险因素。     

Influence of HMB Supplementation and Resistance Training on Cytokine Responses to Resistance Exercise

Purpose: The purpose of this study was to determine the effects of a multinutritional supplement including amino acids, β-hydroxy-β-methylbutyrate (HMB), and carbohydrates on cytokine responses to resistance exercise and training.

Methods: Seventeen healthy, college-aged men were randomly assigned to a Muscle Armor? (MA; Abbott Nutrition, Columbus, OH) or placebo supplement group and 12 weeks of resistance training. An acute resistance exercise protocol was administered at 0, 6, and 12 weeks of training. Venous blood samples at pre-, immediately post-, and 30-minutes postexercise were analyzed via bead multiplex immunoassay for 17 cytokines.

Results: After 12 weeks of training, the MA group exhibited decreased interferon-gamma (IFN-γ) and interleukin (IL)-10. IL-1β differed by group at various times. Granulocyte colony-stimulating factor (G-CSF), granulocyte-macrophage colony-stimulating factor (GM-CSF), IL-6, IL-7, IL-8, IL-12p70, IL-13, IL-17, monocyte chemoattractant protein-1 (MCP-1), and macrophage inflammatory protein-1 beta (MIP-1β) changed over the 12-week training period but did not differ by group.

Conclusions: Twelve weeks of resistance training alters the cytokine response to acute resistance exercise, and supplementation with HMB and amino acids appears to further augment this result.
