简介：无数生物因素被建议了解释早泄(PE)。然而，有精囊(SV)的数据相关PE是稀少的。学习试图评估在SV和PE的尺寸之间的关系。没有PE，代表性的学习与PE和44个志愿者包括了44个门诊病人，并且SV的尺寸被比较。射精的潜伏时间，早泄诊断工具(PEDT)，可勃起的Function-15的国际索引，和健康长期的前列腺炎症状的国家研究所索引的自我估计的intravaginal被用于对症状的评价。比作控制组，PE组有SV的显著地更高的吝啬的前面以后的直径(APD)(P<0.001)。SV截止水平的最佳的吝啬的APD是为PE的9.25公里。在PE组，PEDT与SV的吝啬的APD相比与SV9.25公里的吝啬的APD也是更高的<9.25公里。PEDT显著地与SV的吝啬的APD被相关(r=0.326，P=0.031)。精液的血浆蛋白质被集体spectrometry在六PE和六个匹配的控制盒子之间比较，102蛋白质是至少起来调整或下面调整的1.5褶层，这被显示出。在他们之中，GGT1，LAMC1，和应用软件在PE组是显著地更高的。这些结果显示有SV的更大的吝啬的APD的人可能让更高的PEDT得分。SV的Transrectal超声应该与早泄在病人的评估被考虑。SV可能在SV是为有PE和超声变化的病人的治疗的一个潜在的目标。

简介：关于早泄(PE)的定义，分类和流行有进行中的争论。PE的第一个基于证据的定义与终生的PE被限制到异性爱的人从事阴道交际。不幸地，有PE的抱怨的许多病人不满足这些标准。然而，这些人能作为PE子类型，也就是获得的PE，自然可变PE或象早熟一样之一被诊断射精的机能障碍。不过，这些子类型的有效性被证据还没支持了。一个普遍接受的PE定义的缺席和为数据获得的标准的缺乏导致了报导了冲突率的流行研究。20%的高流行；-30%；可能由于在如此的调查被进行的时间在定义使用的含糊的术语。尽管当为基于人口的流行研究询问了时，许多人可以抱怨PE，仅仅他们的一些将活跃地为他们的抱怨寻求治疗，尽管大多数这些病人将定义与PE适合的症状。获得的PE病人的抱怨可能是更严重的，而经历象早熟一样的病人的抱怨射精的机能障碍与PE的各种各样的形式在人之中似乎最少严重。尽管众多的治疗形式为PE的管理被建议了，仅仅抗抑郁剂和热门麻木的乳脂当前被证明了有效。当任何一个都没被规章的机构同意了治疗形式，进一步的研究不管多么必须被带为PE开发有益的治疗策略。

简介：AbstractBackground:Preterm premature rupture of membranes (PPROM) is associated with high neonatal morbidity and mortality. However, the influences of cesarean section (CS) on neonatal outcomes in preterm pregnancies complicated with PPROM are not well elucidated. The aim of this study was to investigate the influence of delivery modes on neonatal outcomes among pregnant women with PPROM.Methods:A retrospective cross-sectional study was conducted in 39 public hospitals in 14 cities in the mainland of China from January 1st, 2011 to December 31st, 2011. A total of 2756 singleton pregnancies complicated with PPROM were included. Adverse neonatal outcomes including early neonatal death, birth asphyxia, respiratory distress syndrome (RDS), pneumonia, infection, birth trauma, and 5-min/10-min Apgar scores were obtained from the hospital records. Binary variables and ordinal variables were respectively calculated by binary logistic regressions and ordinal regression. Numerical variables were compared by multiple linear regressions.Results:In total, 2756 newborns were involved in the analysis. Among them, 1166 newborns (42.31%) were delivered by CS and 1590 newborns belonged to vaginal delivery (VD) group. The CS proportion of PPROM obviously increased with the increase of gestational age (χ2 = 5.014, P = 0.025). Compared with CS group, VD was associated with a higher risk of total newborns mortality(odds ratio [OR], 2.38; 95% confidence interval [CI], 1.102–5.118; P = 0.027), and a lower level of pneumonia (OR, 0.32; 95% CI, 0.126–0.811; P = 0.016). However, after multivariable adjustment and stratification for gestational age, only pneumonia was significantly related with CS in 28 to 34 weeks group (OR, 0.34; 95% CI, 0.120–0.940; P = 0.038). There were no differences regarding to other adverse outcomes in the two groups, including neonatal mortality, birth asphyxia, Apgar scores, RDS, pneumonia, and sepsis.Conclusions:The proportion of CS of pregnant women with PPROM was very high in China. The mode of delivery does not affect neonatal outcomes of pregnancies complicated with PPROM.

简介：AbstractObjective:Premature ovarian failure (POF) is a disease characterized by irregular menstruation and results in infertility which markedly affects the reproductive health of women. The Salvia miltiorrhiza-Codonopsis pilosula drug pair is effective at treating POF; however, knowledge of the mechanisms of S. miltiorrhiza-C. pilosula in the treatment of POF is lacking. Thus, we carried out network pharmacology and molecular docking to clarify the mechanisms of this drug pair.Methods:The core components and targets of S. miltiorrhiza-C. pilosula were obtained using the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) database and UniProt database, and the disease targets related to POF were searched using different tools to obtain the overlapping target genes of S. miltiorrhiza and C. pilosula. A protein interaction network of the intersection target was constructed using STRING database, and the network of "traditional Chinese medicine-active ingredient-intersection target-disease" and "pathways-targets" was constructed using Cytoscape 3.8.0. The DAVID online tool was also used to determine the gene ontology functions and Kyoto Encyclopedia of Genes and Genomes pathways associated with the intersection target genes. Finally, the binding ability of the drug to the active components and potential targets were predicted using molecular docking.Results:S. miltiorrhizae-C. pilosula had 72 active components, 128 targets, 3,775 POF targets, and 106 common targets. The potential targets were mainly related to the biological processes of DNA-binding transcription factor binding, RNA polymerase II-specific DNA-binding transcription factor binding, transcription factor activity, steroid receptor activity, and hypoxia response. Further, the Kyoto Encyclopedia of Genes and Genomes enrichment pathways included PI3K-Akt signaling pathway, apoptosis, interleukin (IL)-17 signaling pathway, relaxin signaling pathway, and other biological pathways.Conclusion(s):S. miltiorrhiza-C. pilosula can inhibit ovarian granulosa cell apoptosis and improve ovarian hemodynamics through multiple targets and multiple pathways and help treat POF.
