Remifentanil for labour analgesia: a double‐blinded,randomised controlled trial of maternal and neonatal effects of patient‐controlled analgesia versus continuous infusion

This trial aimed to compare the maternal and neonatal effects of remifentanil given by patient‐controlled analgesia (PCA) or continuous infusion for labour analgesia. Patient controlled analgesia was administered using increasing stepwise boluses from 0.1 to 0.4 μg.kg^?1 (0.1 μg.kg^?1 increment, 2 min lockout, n = 30). Continuous infusion used rates from 0.05 to 0.2 μg.kg^?1.min^?1 (0.05 μg.kg^?1.min^?1 increment, n = 30). Dose increments were given on request. Women reported lowest pain scores (median (IQR [range]) of 3 (2–4 [2–5]) for PCA and 4 (3–5.25 [3–7]) for continuous infusion (p = 0.004) at 60 min after the beginning of analgesia. The mean (SD) remifentanil umbilical vein/maternal artery ratio in the PCA and infusion groups were 0.74 (0.45) vs 0.70 (0.52), respectively (p = 0.776). The mean (SD) umbilical artery/umbilical vein ratios were 0.31 (0.12) vs 0.26 (0.07), respectively (p = 0.088). Maternal and neonatal adverse reactions of remifentanil were similar between the two groups. The total remifentanil consumption (median (IQR [range]) during PCA administration was lower than continuous infusion, 1.34 (1.22–1.48 [0.89–1.69]) mg vs 1.49 (1.35–1.61 [1.12–1.70] mg; p = 0.011). The results suggest that remifentanil PCA provides better pain relief and similar placental transfer compared with continuous infusion.     

枸橼酸西地那非对宫腔粘连术后冻融胚胎移植妊娠结局的影响

目的：观察枸橼酸西地那非（万艾可）对宫腔粘连（intrauterine adhesion,IUA）分离术后冻融胚胎移植（frozen embryo transfer,FET）患者妊娠结局的影响。方法：选择2017年1-12月在南京医科大学附属妇产医院行FET的不孕症患者,在进入FET周期前宫腔镜检查确诊IUA,行宫腔镜下IUA分离术,术后复查宫腔镜显示宫腔形态正常行FET,共310例。根据患者是否添加枸橼酸西地那非将患者分为2组,其中A组（对照组）实施激素替代周期FET,共190例;B组（治疗组）为激素替代周期并在患者月经干净后每日阴道给予枸橼酸西地那非50 mg,应用至移植前,共120例。首先比较2组患者的妊娠结局,其次将A组及B组患者进一步分为轻度IUA组和中重度IUA组,比较2组之间的差异。结果：B组临床妊娠率［50.83%（61/120）］高于A组［34.74%（66/190）］,差异有统计学意义（P＜0.05）;B组胚胎种植率［31.17%（72/231）］略高于A组［21.82%（79/362）］,但差异无统计学意义（P＞0.05）。与A组相比,B组轻度IUA患者的临床妊娠率与胚胎种植率差异无统计学意义（P＞0.05）;B组中重度IUA患者的临床妊娠率［44.78%（30/67）］及胚胎种植率［28.46%（37/130）］均高于A组,差异有统计学意义（P＜0.05）。2组间流产率和异位妊娠率比较差异均无统计学意义（P＞0.05）。结论：应用枸橼酸西地那非可提高IUA术后患者子宫内膜容受性,尤其对中重度IUA术后患者可显著提高其FET妊娠率。     

膨体聚四氟乙烯与固体硅胶隆鼻术后肿胀的临床分析比较

目的:临床分析比较膨体聚四氟乙烯和固体硅胶两种假体隆鼻术后的肿胀厚度消退速度,为医生与就医者选择膨体聚四氟乙烯或者固体硅胶假体提供临床资料依据。方法:将就医者分为膨体聚四氟乙烯假体组和固体硅胶假体组,运用面部三维重建技术,观察比较两组就医者在隆鼻术前、术后1天、术后3天、术后5天和术后7天肿胀厚度的变化。结果:隆鼻术后1~7天,无论是膨体聚四氟乙烯组还是固体硅胶组肿胀厚度都降低。术后1、3、5、7天比较膨体聚四氟乙烯组与固体硅胶组肿胀厚度,差异无统计学意义(P0.05)。结论:膨体聚四氟乙烯组与固体硅胶组隆鼻术后肿胀厚度消退速度趋于一致,无显著差异。从术后肿胀的角度告知医生和就医者,在隆鼻术时选择膨体聚四氟乙烯或者固体硅胶假体均可,在肿胀厚度消退速度方面的区别不大。

Endothelial cell surface vimentin binding peptide induces angiogenesis under hypoxic/ischemic conditions

We have previously identified several angiogenic peptides that bind cell surface proteins by screening a phage display peptide library on human umbilical endothelial cells exposed to hypoxic conditions. In this study we describe one of the selected peptides, SP. We found by protein precipitation of endothelial cell lysates that the 12 amino acid SP peptide binds cell surface vimentin. Surprisingly, vimentin was detected on the cell surface of about 30% of intact endothelial cells under both normoxic and hypoxic conditions, as was demonstrated by fluorocytometric analysis on viable cells. The assessment of SP in the induction of angiogenesis was established by a significant increase in endothelial cell proliferation and tube formation under hypoxic conditions and not under normoxic conditions. Cell proliferation and tube length increased two-fold in endothelial cells in the presence of 10 ng/ml SP peptide when compared to controls. The specificity of SP binding to vimentin was demonstrated by SP inhibition of anti-vimentin binding and by the inhibition of tube formation in cells transfected with siRNA against vimentin. Local intramuscular administrations of the peptide SP to ischemic hind limbs using the mouse hind limb ischemia model, demonstrated that SP inoculated at 1 and 10 μg, improved blood perfusion compared to inoculations with an irrelevant peptide or PBS. The recovery of blood perfusion correlated with the increase in the number of detectable capillaries in the ischemic limb. The development of novel peptides for the induction of pro-angiogenic activity may pave the way for new therapeutic strategies in the treatment of cardiovascular ischemic diseases.
