600例健康体检妇女阴道微生态状况分析

目的研究深圳宝安地区健康妇女阴道微生态状况。方法对2011年9月至2012年2月在深圳宝安区人民医院体检中心进行健康体检的600例妇女阴道分泌物进行检测,检测指标包括清洁度、念珠菌、滴虫、阴道酸碱度、唾液酸苷酶、白细胞酯酶、过氧化氢（H2O2）浓度。结果研究对象中阴道微生态正常328例（54．67％）,微生态失调者272例（45．33％）;阴道微生态失调者中,微生态功能检测阳性率及致病菌的检出率均明显大于微生态正常者,差异有统计学意义（P〈0．05）。结论深圳宝安地区健康体检妇女部分患有阴道炎或存在阴道微生态失调或亚失调状态;阴道微生态联合检测法简便、快速、价廉实用,值得推广。     

改良丁字带对妇科阴式手术后阴道微生态的影响

目的 探讨改良丁字带对比传统丁字带对妇科阴式手术后患者阴道微生态的影响。方法 选择妇科阴式手术患者186例作为研究对象,随机分为两组,观察组93例使用改良丁字带固定,对照组93例使用传统丁字带固定。对比分析两组患者术后阴道微生态,敷料污染,引流管阻塞、脱落,皮肤受损,排尿困难等的发生情况。结果 观察组阴道微生态失衡发生率为23.66%,敷料污染发生率为29.03%,引流管阻塞发生率为7.52%,皮肤受损发生率为3.23%,均明显低于对照组,差异具有统计学意义（均P<0.05）。结论 妇科阴式手术后使用改良丁字带固定能够减少手术患者阴道微生态失衡及相关并发症的发生率,提高患者生活质量。     

Histological studies on the vaginal plate and vaginal epithelium in androgenized rats

Summary The present work is a histological study on the epithelium of the vaginal plate and vagina proper of intact rats, 5–45 days old, and of rats which were injected with 1.5 mg testosterone propionate at the age of 5 days (androgenized) and studied at different ages from 6–45 days. Moreover, the vaginal epithelium in adult androgenized rats was studied.A perforation of the vaginal plate and an external orifice of the vagina was seen in intact rats about 35 days old. The perforation resulted from cornification in scattered, later confluencing, regions in the epithelium of the plate.The androgenized rats developed a precocious vaginal opening at 12 days of age. Also in these animals the perforation of the plate resulted from a cornification in the center of the strongly thickened plate. After a lumen had developed the plate region presented a transitional epithelium. This was transformed into a stratified squamous epithelium at about 35–45 days, that is when the first oestrus occurred in intact controls. In contrast to the strong reaction to testosterone in the epithelium of the vaginal plate no effects could be seen in the vaginal epithelium proper, with the exception of some leucocytic infiltration.The adult androgenized rats had a cornified vaginal epithelium which in two cases showed some leucocytic infiltration.

Development and evaluation of acid-buffering bioadhesive vaginal tablet for mixed vaginal infections

An acid-buffering bioadhesive vaginal tablet was developed for the treatment of genitourinary tract infections. From the bioadhesion experiment and release studies it was found that polycarbophil and sodium carboxymethylcellulose is a good combination for an acid-buffering bioadhesive vaginal tablet. Sodium monocitrate was used as a buffering agent to provide acidic pH (4.4), which is an attribute of a healthy vagina. The effervescent mixture (citric acid and sodium bicarbonate) along with a superdisintegrant (Ac-Di-sol) was used to enhance the swellability of the bioadhesive tablet. The drugs clotrimazole (antifungal) and metronidazole (antiprotozoal as well as an antibacterial) were used in the formulation along with Lactobacillus acidophilus spores to treat mixed vaginal infections. From the ex vivo retention study it was found that the bioadhesive polymers hold the tablet for more than 24 hours inside the vaginal tube. The hardness of the acid-buffering bioadhesive vaginal tablet was optimized, at 4 to 5 kg hardness the swelling was found to be good and the cumulative release profile of the developed tablet was matched with a marketed conventional tablet (Infa-V). The in vitro spreadability of the swelled tablet was comparable to the marketed gel. In the in vitro antimicrobial study it was found that the acid-buffering bioadhesive tablet produces better antimicrobial action than marketed intravaginal drug delivery systems (Infa-V, Candid-V and Canesten 1).     

乳酸菌阴道胶囊辅助治疗对未足月胎膜早破的疗效及对其阴道微生态的影响

目的 观察乳酸菌阴道胶囊辅助治疗对未足月胎膜早破的治疗效果,并探讨其对阴道微生态的影响。 方法 86例未足月胎膜早破患者采用随机数表分为常规组与研究组,各43例。常规组予以常规治疗,研究组予以乳酸菌阴道胶囊联合常规治疗。比较治疗后两组阴道微生态、胎儿宫内感染率和分娩方式、母体和胎儿不良妊娠结局发生情况。 结果 治疗后研究组Chao1指数和Shannon指数均高于常规组(均P结论 乳酸菌阴道胶囊辅助治疗未足月胎膜早破相较于常规治疗可改善阴道微生态,还可降低胎儿宫内感染率、剖宫产率,减少母体和围产儿不良妊娠结局的发生。
