目的 探讨子宫内膜异位症（EMT）患者卵泡液来源的外泌体差异微小RNA（miRNA）对卵母细胞质量的影响。方法 收集2021年12月—2022年3月在广州市第一人民医院生殖医学中心进行体外受精-胚胎移植/卵细胞浆内单精子注射助孕的20例不孕症患者的卵泡液,分为EMT组（EMT不孕症患者10例）和对照组（单纯男性因素不孕症患者10例）。采用高通量测序对卵泡液外泌体微小RNA（miRNA）谱进行分析,选出具有组间差异的miRNAs。结果 与单纯男性因素不孕患者相比,EMT组有18个外泌体miRNAs差异有统计学意义,其中上调9个、下调9个。靶基因预测并采用GO和KEGG富集分析发现,这些靶基因主要参与磷脂酰肌醇-3-激酶/蛋白激酶B（ PI3K-Akt）、核苷酸结合寡聚结构域NOD样受体、Ras等信号通路。结论 EMT患者卵泡液来源的外泌体miRNA存在差异,差异的外泌体miRNAs可能通过多个信号通路影响EMT患者卵母细胞质量。

Objective To investigate the effect of differential microRNA（miRNA）derived from follicular fluid exosomes on oocyte quality in patients with endometriosis（EMT）. Methods Follicular fluid was collected from 20 infertile patients undergoing IVF-ET / ICSI in the Reproductive Medicine Center of Guangzhou First People's Hospital from December 2021 to March 2022,including EMT group（10 patients with EMT infertility）and control group（10 patients with simple male factor infertility）．The miRNA spectrum in follicular fluid exosomes was analyzed by high-throughput sequencing and miRNAs with differences between groups were selected. Results Compared with patients with infertility due to simple male factors,there were significant differences in 18 exosomal miRNAs in the EMT group,of which 9 were up-regulated and 9 were down-regulated．GO and KEGG enrichment analysis showed that these target genes were mainly involved in phosphatidylinositol-3-kinase / protein kinase B,Nucleotide binding oligomerization domain-like receptor and other signaling pathways. Conclusions There are differences in follicular fluid-derived exosomal miRNAs in EMT patients．Differential exosomal miRNAs may affect oocyte quality in EMT patients through multiple signaling pathways．

目的 探讨肠道菌群多样性及丰度在抗结核治疗强化期的变化。方法 收集广州市胸科医院20例初治菌阳肺结核患者使用强化方案治疗1周及强化期结束的粪便标本,所有标本进行16S rDNA测序,进行生物信息学分析。结果 强化期结束治疗组的Alpha多样性指标Chao1和observed_otus指数分别为(97.8±28.3)和(97.6±28.2),高于治疗1周组的(81±34.7)和(81±34.7),差异有统计学意义(P=0.04;P=0.038)。基于加权和未加权Unifrac距离的PCoA分析显示两组整体菌群结构无明显差异。在相对丰度较高的菌科中,强化期结束治疗组的拟杆菌科、肠球菌科、肠杆菌科、丹毒菌科、卟啉单胞菌科、双歧杆菌科等相对丰度下降,毛螺菌科、梭杆菌科、普氏菌科、瘤胃球菌科、韦氏菌科等相对丰度增加。通过线性判别分析效应量LEfse分析两组数据,发现在属水平上,厚壁菌门的瘤胃球菌、乳杆菌及放线菌门的柯林氏菌为组间显著差异菌种。结论 强化期治疗结束与治疗1周相比,肠道菌群多样性增加,但肠道菌群结构无明显差异。肠道拟杆菌科丰度减少,毛螺菌科丰度增加。

Objective To investigate the changes in the diversity and abundance of intestinal flora during the intensive period of anti-tuberculosis treatment. Methods Stool specimens from 20 patients with newly treated bacteria-positive pulmonary tuberculosis in Guangzhou Chest Hospital, which were treated with the intensive treatment for 1 week and whole intensive treatment, were collected. All the specimens were subjected to 16S rDNA sequencing and bioinformatics analysis. Results The Alpha diversity index Chao1 and observed_otus index of the treatment group with whole process were (97.8±28.3) and (97.6±28.2) respectively, which were higher than (81±34.7) and (81±34.7) of the 1-week treatment group, which had statistical differences (P=0.04;P=0.038). PCoA analysis based on weighted and unweighted Unifrac distance showed that there was no significant difference in the overall flora community structure between the two groups. Among the bacteria families with higher relative abundance, the relative abundance of Bacteroidaceae,Enterococcaceae,Enterobacteriaceae,Erysipelotrichaceae,Porphyromonadaceae and Bifidobacteriaceae in the treatment group with whole process decreased, the relative abundance content of Lachnodoiraceae,Fusobacteriaceae,Prevotellaceae, Rumincoccaceae, and Veillonellaceae increased. By using linear discriminant analysis effect size (LEfse) to analyze the two sets of data, it was found that at the genus level,Rumincoccaceae of Firmicutes and Lactobacillus;Collinsella of Actinobacteria were significantly different species between the groups. Conclusion Compared with 1 week of treatment, the diversity of intestinal flora increased at the end of intensive treatment, but there was no significant difference in the community structure of intestinal flora. The abundance of intestinal Bacteroidaceae decreased, and the abundance of Lachnodoiraceae increased.

目的 根据巨脑回畸形的病理特点,对比其它影像检查,研究该病的超声特点,探讨新生儿期巨脑回畸形的超声诊断价值。方法 对5例新生儿巨脑回畸形的患儿的超声资料进行分析。结果 5例超声检查均表现为大脑脑回明显宽大,脑沟、脑回稀少,皮层明显增厚,大脑表面光滑,且5例均伴有不同程度的其它颅脑畸形。结论 新生儿巨脑回畸形具有一定的超声特征,超声检查在新生儿巨脑回畸形的诊断中具有重要的价值。

目的 分析影响接受夫精宫腔内人工授精(IUI)助孕患者临床妊娠率的有关因素。方法 选择225例接受IUI助孕共400周期的不孕症患者,回顾分析女方年龄、治疗方案、hCG日子宫内膜厚度、IUI周期数与临床妊娠率的关系。结果 女方年龄>38岁的临床妊娠率(8.22%)低于年龄<30岁(21.74%)和30~38岁(17.48%),P<0.05;促排卵方案(CC、HMG、CC+HMG)临床妊娠率分别为19.05%、19.66%和14.71%,高于自然周期的临床妊娠率7.14%,P<0.05;hCG日子宫内膜厚度≥8 mm组的临床妊娠率(23.56%)高于内膜<8 mm组的临床妊娠率(13.27%),P<0.05;第1至第5周期的IUI临床妊娠率分别为21.30%、15.60%、9.38%、0%和0%,多次重复IUI周期数差异有统计学意义(P<0.05)。结论 女方年龄、hCG日子宫内膜厚度、治疗方案均会影响IUI的临床妊娠率,但增加IUI的治疗周期数并不能提高临床妊娠率,应综合各种因素再次评估患者的妊娠率,必要时进一步查找多次助孕失败的原因或改行IVF-ET助孕治疗。

Objective To analyze the relative factors which influence the clinical pregnancy rates of patients accepted intrauterine insemination with husband's sperm. Methods 225 cases of infertile patients accepted IUI treatment were selected, 400 cycles were included and the clinical data were analyzed retrospectively. Observing the relationship between the age of women, treatment options, endometrial thickness on hCG injection day, cycles of IUI and pregnancy rates. Results The clinical pregnancy rates of women less than 30 years old(21.74%) were higher than aged between 30 to 38 years old(17.48%) and more than aged 38 years old(8.22%), P<0.05.The clinical pregnancy rates of ovulation induction options(CC、HMG、CC+HMG) were 19.05%, 19.66% and 14.71%, higher than the pregnancy rates of natural cycle 7.14% significantly, P<0.05. The pregnancy rates of the group of endometrial thickness ≥8mm on hCG injection day were 23.56%, higher than the group of endometrial thickness <8 mm 13.27%, P<0.05. The clinical pregnancy rates of 1 to 5 cycles IUI were 21.30%, 15.60%, 9.38%, 0% and 0% respectively, the difference of repeating the IUI cycles’ number was statistical significance (P<0.05). Conclusion The ages of women, endometrial thickness on hCG injection days and treatment options can affect the clinical pregnancy rates. Extending the number of IUI treatment cycles can not increase the pregnancy rates of IUI. All the factors should be comprehensive to assess the patient's pregnancy rates again, to find more reasons further for the failure of assisted reproduction or turn to IVF-ET assisted reproduction treatment when it is necessary.
