阴道微生态的影响因素及致病性

Influencing factors and pathogenicity of vaginal microecology

阴道微生态是由阴道内的微生态菌群、机体的内分泌调节和解剖结构共同组成的。正常阴道内有多种微生物存在，相互之间形成动态平衡。该平衡一旦被打破，即可导致疾病状态。影响阴道微生态的因素有很多，包括年龄、月经、妊娠等生理因素，糖尿病、宫颈病变等病理因素，激素、抗生素、维生素C、免疫抑制荆等药物因素，手术、生活方式以及气候、遗传因素。明确这些影响因素有助于对疾病的认识与防治。

The vaginal microecology depends upon vaginal flora, endocrine regulation and anatomic structure of vagina itself. Kinds of microorganism exist in the normal vagina and they keep dynamic balances. Once the balance is broken, disease can occur. There are many influencing factors of vaginal microecology, including physiological factors （ such as age, menstruation and pregnancy）, pathological factors （such as diabetes mellitus, cervical lesions ）, drugs （such as hormone, antibiotics, vitamin C and immunodepressants ）, surgical operation, life style, climatic factor and genetic factors. Determination of these influencing factors is helpful to recognize and prevent the diseases.
