新式非脱垂子宫阴式全子宫切除术45例报告 总被引:3,自引:1,他引:2
目的探讨非脱垂子宫经阴道改良切除的可行性及方法。方法将103例子宫肌瘤、子宫腺肌瘤、功能性子宫出血等需行全子宫切除术的患者随机分为两组,常规经腹式全子宫切除术(腹式组)58例,经阴道全子宫切除术(阴式组)45例,比较两种手术方法的优劣。结果阴式组较腹式组手术时间短,术中出血少,术后痛苦少;48h内肛门排气阴式组40例(88.9%),腹式组31例(53.4%);平均住院天数阴式组5.1d,腹式组7.1d。结论新式非脱垂子宫的阴式全子宫切除术相对于经腹式全子宫切除术有一定的优势,但要严格选择其手术适应证。 相似文献

Intracellular pH (pHi) is known to modulate contraction. Neonatal tissues can differ from adult tissue in contractile response to stimuli known
to alter pHi e.g. hypoxia. Changes of pH are attenuated by buffering, thus any difference in buffering power (β) between tissues could
affect their functional response to pHi perturbation. Similarly the extent to which any extracellular pH (pHo) alteration is transmitted into a pHi change will also influence function. We have therefore determined the intrinsic β and effect of pHo change on pHi in neonatal and adult ureteric, uterine and gastric smooth muscles using the pH-sensitive fluorophore carboxy-SNARF. β was
found to be similar in the three adult tissues, but there were significant differences between neonatal tissues. In contrast,
we found little difference in the amount of pHi change produced by pHo change between neonatal and adult tissues from the same smooth muscle, but a difference between smooth muscles. These data
highlight significant differences between smooth muscles and their developmental state, which may contribute to different
degrees of protection when pH is perturbed.

作者以1%乙酸冲洗SD大鼠子宫内膜,获得子宫内膜酸溶性提取物。利用琼脂糖弥散法和电泳凝胶琼脂糖弥散法抗菌试验发现,子宫内膜提取物有三条主蛋白带对致病性大肠杆菌ML-35P耐药株有强抗菌活性,这三条抗菌蛋白带命名为RatUP-1,RatUP-2和RatUP-3,分别占子宫内膜提取物总蛋白量的4.5%,5.7%和6.6%。虽然提取物存在溶菌的活性,但其含量甚微,在AU一PAGE图谱上亦未能显现溶菌酶条带。本实验的结果提示子宫内膜合成一类抗菌多肽,可能在子宫抗菌机制中发挥重要作用。 相似文献

The uterus plays a major role in reproductive physiology. Numerous studies have shown that estradiol and progesterone exert their effects by binding to receptors within the cytoplasm of uterine cells and translocating these receptors to the nuclei where they presumably alter genomic activity. The extent of the steroid-receptor interaction in the cytoplasm and the nucleus is well correlated with uterine growth. Other physiological changes that take place in the uterus are also correlated with variations in the cytoplasmic and nuclear steroid receptor levels observed during different stages of reproductive cycle. In the rat, the uterus also exerts an inhibitory effect on the hormone-induced maternal and copulatory behaviors. Hysterectomy shortens the latency for the induction of maternal behavior and enhances sexual receptivity and proceptivity in ovariectomized, hormone treated rats. The mechanism of this inhibitory effect is not fully understood; however, it seems that the steroid binding capacity of the uterus mediates its behavioral influence. Thus when this capacity is reduced, as evidenced by lower levels of cytoplasmic estrogen receptors in long-term gonadectomized animals, the uterus loses its inhibitory effect on copulatory behavior. 相似文献

目的探讨中国子宫畸形患者中HOXA13基因同源结构域是否存在突变及其相关性分析。方法国外文献报道手-足-生殖器综合征(hand-foot-genital syndrome,HFGS)患者中发现HOXA13基因2号外显子同源结构域存在点突变,而此综合征的女性患者部分症状表现为子宫畸形,因此对58例中国子宫畸形患者和54例正常对照者进行HOXA13基因同源结构域检测,PCR扩增目的片断后自动化测序分析基因2号外显子同源结构域区域。结果HOXA13基因同源结构域直接自动化测序分析结果显示,在患者和对照者中均没有突变发生。结论中国妇女子宫畸形的发生可能与HOXA13基因同源结构域突变无关。 相似文献

Nucleolar organizer regions in uterine sarcomas 总被引:3,自引:0,他引:3

Summary Nucleolar organizer regions demonstrable by silver staining technique (AgNORs) are loops of nucleolar DNA transcribing to ribosomal RNA. This report quantifies AgNORs in normal endometrium and myometrium, and in leiomyomas and homologous sarcomas of the uterus. The mean AgNOR number in leiomyosarcomas was significantly higher than that in normal myometrium and that in leiomyomas, whereas no significant difference was observed between normal myometrium and leiomyomas. The mean AgNOR count in low-grade endometrial stromal sarcomas was significantly higher than that in normal endometrial stroma, and significantly lower than that in the high-grade variant of the same tumour. The epithelial component of malignant mixed müllerian tumours exhibited a significantly higher mean AgNOR number than normal endometrial epithelium, and the stromal component of these tumours showed a significantly higher mean AgNOR count than normal endometrial stroma and normal myometrium, respectively. The AgNOR count was significantly correlated with the mitotic rate in leiomyosarcomas, in high-grade endometrial stromal sarcomas, and in the epithelial and mesenchymal portions of mixed müllerian tumours, whereas no statistically significant correlation was observed in low-grade endometrial stromal sarcomas. Increased AgNOR counts have been reported for some kinds of malignant tumours in various organs, compared with normal tissues and benign tumours. This study demonstrates a similar increase when homologous uterine sarcomas are compared with histogenetically related normal and neoplastic tissues. AgNOR counting might be a useful adjunct in the classification and grading of uterine tumours. 相似文献

感染因素或宫腔手术操作导致的子宫内膜损伤阻碍胚胎的着床和发育,严重影响妇女的身心健康与生育能力。但目前治疗手段有限且效果欠佳。干细胞具有自我更新和分化潜能,在病变损伤组织的修复过程中发挥重要作用。骨髓间充质干细胞、脐带间充质干细胞、子宫内膜干细胞、脂肪干细胞和人羊膜上皮细胞等多种干细胞治疗子宫内膜损伤已在动物模型和临床研究中开展,并展现出巨大的潜力。干细胞治疗可促进子宫内膜细胞再生,改善子宫内膜厚度和微血管密度,提高受孕率并改善生育结局。干细胞治疗从形态和功能上改善子宫内膜,促进月经和生殖功能的恢复,为治疗子宫内膜损伤提供一种新策略。 相似文献
