中药天癸胶囊治疗多囊卵巢综合征的随机对照疗效观察

背景：多囊卵巢综合征（polycystic ovary syndrome,PCOS）是一组复杂的症候群。许多研究表明,中草药可作为治疗PCOS的替代疗法,故分析和观察中国传统医药对PCOS的疗效是必要和有价值的。目的：观察中药天癸胶囊治疗PCOS的有效性,比较天癸胶囊与二甲双胍和达英-35治疗PCOS在调整卵巢功能、改善胰岛素抵抗和改变卵巢形态学等方面的效果。设计、场所、对象和干预措施：收集复旦大学附属妇产科医院门诊符合PCOS诊断标准的PCOS患者共47例,随机分入A、B、C三个治疗组。A组（19例）给予天癸胶囊治疗,B组（17例）给予二甲双胍治疗,C组（11例）给予达英-35治疗,3组均治疗3个月。主要结局指标：检测治疗前后雄激素（testosterone,T）、性激素结合球蛋白（sex hormone binding globulin,SHBG）、硫酸脱氢表雄酮（dehydroepiandrosterone sulfate,DHEA-S）水平以及游离雄激素指数（freeandrogenindex,FAI）、空腹血糖（fasting blood glucose,FPG）、空腹胰岛素（fastinginsulin,FINS）、胰岛素稳态模型指数（hemeostasis model assessment-insulin resistance,HOMA-IR）、胰岛素敏感指数（insulinsensitive index,ISI）和双侧卵巢体积的变化。结果：A组治疗后血清T、SHBG水平及FAI、FINS下降（P〈0.05）,双侧卵巢缩小（P〈0.05）,血清DHEA-S水平增加（P〈0.05）,FPG有增加趋势但无统计学意义。治疗3个月后3组间血清T水平比较虽无差异,但在降低FAI及增加血SHBG作用方面A组比B组强,比C组弱;3种药物降低FINS水平作用相似,但仅B组治疗后胰岛素敏感性增加;3组治疗后FPG均似有增加趋势,但C组FPG水平增加幅度最大。结论：中药天癸胶囊改善高雄激素血症作用比达英-35弱,优于二甲双胍;改善高胰岛素血症作用比二甲双胍弱,优于达英-35。天癸胶囊在不抑制下丘脑-垂体-卵巢轴功能的基础上,通过调整卵巢功能、改善胰岛素水平及改变卵巢形态等多方面治疗PCOS。以上结果值得进一步扩大样本量予以证实。

Effect of different modeling time on intestinal bacteria in letrozole induced PCOS rats

Objective: The differences of ovarian morphology, reproductive hormones, glucose and lipid metabolism and intestinal bacteria in rats with polycystic ovary syndrome (PCOS) induced by triazole were compared. Method: Eighteen 21 SPF female SD rats were randomly divided into group A (3-week group), group B (5-week group) and group D (control group) by random number table.Group A received letrozole + CMC-Na mixture by gavage in the first 3 weeks and CMC-Na solution by gavage in the last 2 weeks, group B received letrozole + CMC-Na mixture by gavage for 5 weeks, and group D received CMC-Na solution by gavage for 5 weeks, and all three groups of rats were fed with normal diet.At the end of gavage, the body weight of rats in each group was observed, the histological changes of ovaries were observed by hematoxylin-eosin (HE) staining, the serum levels of estradiol (E2), follicle stimulating hormone (FSH), luteinizing hormone (LH), testosterone (T), total cholesterol (TC), triglyceride (TG), fasting blood glucose (Glu), fasting insulin (FINS) and lipopolysaccharide (LPS) were measured by enzyme-linked immunosorbent assay (ELISA), and the LH/FSH ratio and insulin resistance index (HOMA IR) were calculated; the intestinal bacteria of rats were detected by 16S rRNA technique. Result: 1. Comparison of ovary histomorphology: Under light microscope, multiple luteum and oocytes were observed in mature follicles in group D, and granulosa cells were orderly arranged and multilayered, without cystic dilated follicles. There were no mature follicles in the ovarian tissues of group A and GROUP B. The follicles were irregular in structure and more cystic dilated follicles were visible. The number of granular cells in some follicles decreased or even disappeared. 2. Comparison of sex hormone levels: compared with group D, T level in group B was significantly increased (P < 0.001), and T level in group A had an upward trend (P > 0.05); The LH/FSH levels in group A and B were significantly increased (P < 0.001; P < 0.001). Compared with group A, E2 in group B was significantly decreased (P < 0.05) and T was significantly increased (P < 0.01). 3. Comparison of glucose and lipid metabolism levels: Compared with group D, TC levels in groups A and B were significantly increased (P < 0.01; P < 0.01). Compared with group A, TG in group B was significantly increased (P < 0.05). There were no significant differences in Glu, FINS and HOMA-IR levels among all groups. 4. Comparison of LPS levels: Compared with group D, the serum LPS levels of rats in groups A and B were significantly increased (P < 0.001; P < 0.01). 5. Intestinal flora analysis and comparison: At the phylum level, compared with group D, the abundance of Firmicutes in group B increased (P < 0.01), Firmicutes in group A showed an upward trend (P > 0.05), and the abundance of Bacteroidetes in groups A and B decreased (P < 0.05). At the genus level, compared with group D, Lactobacillus in group B increased (P < 0.01). The results of LEfSe analysis showed that there were differences in the composition of various intestinal bacteria among the three groups (LDA > 3).Conclusion: The phenotype of PCOS rats was related to the length of modeling, and the phenotypic characteristics of PCOS in rats at 5 weeks of modeling were more typical than those in rats at 3 weeks of modeling; PCOS can cause changes in intestinal flora, and the changes in the structure of intestinal flora between groups are related to different modeling duration.

Effect of Acupuncture on Ovary Morphology and Function in DHEA-Induced Polycystic Ovary Syndrome Model Rats

Objective To investigate the effects of acupuncture on ovary morphology and function in dehydroepiandrosterone(DHEA)-induced polycystic ovary syndrome(PCOS)model rats.Methods A total of 40 adult female Wistar rats were randomly allocated to 4 groups by a random number table,including control,model,metformin and acupuncture groups,10 rats in each group.PCOS rat model was developed by injecting with DHEA(6 mg/100 g body weight)in 0.2 mL of oil subcutaneously.Electrical stimulation(2 Hz,3 mA)was applied to Guanyuan(CV 4),Zigong(EX-CA1)and Qihai(CV 6)acupoints for 30 min daily in the acupuncture group,and metformin(200 mg/kg)was given to rats in the metformin group,both once per day for 21 consecutive days,and rats in the normal group was fed with normal saline and fed regularly.After 21 days of administration,the rat blood samples were collected for detecting the reproductive hormonal levels[luteinizing hormone(LH),follicle stimulating hormone(FSH),estradiol(E2),progesterone(P),testosterone(T)]and inflammatory factors(visfatin,IL-6)analysis.Ovary tissue was used for histopathological analysis.Results Compared with the model group,rats in the acupuncture and metformin groups were significantly lower in weight gain,FSH,LH and T levels,and E2 and P levels significantly increased(alll P<0.05).Meanwhile,LH and FSH levels were significantly decreased,and P,T and E2 levels significantly increased in the acupuncture group,compared with the metformin group(P<0.05).Compared with the model group,IL-6 and visfatin levels were significantly decreased in the acupuncture and metformin groups(P<0.05).There were no significant differences in IL-6 and visfatin levels between the acupuncture and metformin groups(P>0.05).Ovarian diameter in the acupuncture and metformin groups were smaller than the model group(P<0.05).However,there were no significant differences in ovarian diameters between the acupuncture and metformin groups(P>0.05).Conclusion Acupuncture might improve ovary morphology and its function in DHEA-induced PCOS model rats.

Role of TGF-β1 in the Formation of Ovarian Interstitial Fibrosis in PCOS Rat

Objective To study the role of TGF-β1 in the formation of interstitial fibrosis and capsular thickening in the PCOS rats.
Methods PCOS rat model were established by subcutaneous injection DHEA. Estradiol （E2）, testosterone （T）, follicular stimulating hormone （FSH）, luteinizing hormone （LH）, LH/FSH and fasting insulin （FINS） hormone values of the model were tested by microparticle enzyme immunoassay, the pathohistology of PCOS rat ovaries was observed by HE staining, and their ultrastructure was tested by transmission electron microscope （TEM）. The expressions of TGF-β1 in PCOS group （n =20）, and control group（n=20） were detected and evaluated by immunohistochemistry and image analysis system.
Results The results of serum E2, T, LH/FSH, FINS, the ovarian pathological-histology and the ultrastructure showed that the model was established successfully. Compared with control group： there was no significant difference of TGF-β1 expression intensity in oocytes, granulosa cells of the different developing stages of follicle in PCOS （P〉0.05）. But it was markedly higher expressed in the theca cells of antral follicles （P〈0.01）, and stromal cells （P〈0.05） in PCOS group than in control group.
Conclusion The abnormal expression of TGF-β1 in PCOS is the main cause of capsular thickening and interstitial fibrosis. TGF-β1 also takes part in regulating PCOS follicle development and atresia.
