[Exploration of the meridian differentiation law in polycystic ovarian syndrome of hirsutism based on data mining technology].

OBJECTIVE: To analyze the distribution characteristics of hirsutism and the law of meridian differentiation in polycystic ovarian syndrome (PCOS). METHODS: For the patients of PCOS, the modified Ferriman-Gallwey score (mF-G score) was adopted to evaluate the hirsutism distribution. The clementine data mining software was used to analyze the distribution region of hirsutism and the correlation with meridian. RESULTS: A total of 141 patients of PCOS participated in the study. The most common regions of hirsutism were in the upper lip (50.35%) and the lower abdomen (34.04%). The higher frequencies of hirsutism at two regions were at the upper lip and lower abdomen (24.82%), the upper lip and chest (12.06%) and the upper lip and thigh (11.35%). In the analysis on the correlation of the upper lip, lower abdomen and chest with other regions, hirsutism was more common in the nearby regions. In reference to the running course of meridian, the frequencies of hirsutism from high to low were the conception vessel (63.12%), the thoroughfare vessel (61.70%), the liver meridian of foot-jueyin (58.16%) and the stomach meridian of foot-yangming (57.45%). According to Miraculous Pivot: Yinyang Twenty-Five Persons, the high incidence of hirsutism (59.57%） resulted from the change of qi and blood in yangming meridian. . CONCLUSION: Blood plays the important role in the growth of body hair. Regarding the yinyang attribution, the incidence of hirsutism at the yin regions is higher than the yang regions. The occurrence of hirsutism is closely related to qi and blood changes in meridians. The conception vessel, the thoroughfare vessel, the liver meridian of foot-jueyin and yangming meridian act highly on the disease.

[Effect of Bushen Huoxue Recipe on Paracrine Gene Expression Profiling of Uterine Natural Killer Cells and Uterine Stromal Cells].

Objective To observe the effect of Bushen Huoxue Recipe (BHR) on paracrine gene expression profiling of uterine natural killer cells (uNK cells) and uterine stromal cells. Methods Human stromal cells were extracted from proliferative phase endometrium of child-bearing age females, which were then divided into the blank group, the control group, and the BHR group. DMEM/F12 was added in cells of the BHR group to dilute into final concentration of 2 mg/mL herbal liquor. Equal volume of DMEM/ F12 was added to cells in the normal group and the control group. Cells in the control group and the BHR group were cultured for 24 h, with 20% serum-free DMEM plus 80% uNK cell secretion extracting solution added. Then they were cultured in 5% CΟ2 at 37 °C for 6 h. Total RNAs were extracted after culture. The gene expression profile of stromal cells was detected using gene chip technology. At the same time mR- NA and protein expressions of chemokine (C-X-C motif) ligand 1 (CXCL1), intercellular cell adhesion molecule-1 (ICAM-1) , IL-8, and leukocyte inhibitor factor (LIF) were screened and detected using qRT- PCR and ELISA. Results Compared with the blank group, profiles of differentiated genes with 4-fold in- crease (a total of 63 genes) were basically agreeable in the control group and the BHR group. Compared with the control group, IL-15 receptor alpha (IL-15RA) was up-regulated by 1. 27 times, vascular endotheli- ai growth factor (VEGF) up-regulated by 1. 55 times, LIF up-regulated by 1. 45 times, IL-8 up-regulated by 1. 10 times, IL-11 up-regulated by 1. 23 times, transforming growth factor-ß (TGF-ß) up-regulated by 1. 40 times, epidermal growth factor (EGF) up-regulated by 1. 10 times, chemokine (C-C motif) ligand 8 (CCL8) up-regulated by 1.13 times, transporter 1 (TAP1 ) up-regulated by 1. 02 times, chemokine (C-X-C motif) receptor 2 (CXCR2) up-regulated by 1. 22 times, ICAM-1 up-regulated by 1. 15 times (P <0. 05) in the BHR group. Conclusion uNK paracrine played an important role in elevating endometrial receptivity and embry- o implantation, and BHR could improve and elevate the function of this paracrine system.

Bu Shen Huo Xue decoction restores endometrial leukemia-inhibitory factor but not Angiopoietin-2 expression, and improves uterine receptivity in the controlled ovarian stimulation rat model.

Leukemia-inhibitory factor (LIF) and Angiopoietin-2 (Ang-2) are important factors in fertility. In the present study, it was investigated whether Bu Shen Huo Xue Decoction (BSHXD) prevents controlled ovarian hyperstimulation (COH) treatment-induced changes in endometrial LIF and Ang-2 expression and whether it has an effect on the number of implantation sites and live births in rats. Uteri were collected on day (D) 3, 4 and 5 of pregnancy, and LIF and Ang-2 protein and mRNA expression were detected using western blot analysis and quantitative polymerase chain reaction. On pregnancy D10, the average number of implantation sites was observed. The number of live births from each group was recorded. The results indicated that BSHXD treatment markedly increased the number of live births by restoring endometrial LIF expression and the implantation capacity in the COH rat model. In addition, no association was identified between LIF and Ang-2 expression. Therefore, this suggests that BSHXD may be useful for female reproduction.

Effects of "Danzhi Decoction" on Chronic Pelvic Pain, Hemodynamics, and Proinflammatory Factors in the Murine Model of Sequelae of Pelvic Inflammatory Disease.

Objective. To evaluate the effect of Danzhi decoction (DZD) on chronic pelvic pain (CPP), hemodynamics, and proinflammatory factors of sequelae of pelvic inflammatory diseases (SPID) in murine model. Methods. SPID mice were randomly treated with high-dose DZD, mid-dose DZD, low-dose DZD, aspirin, and vehicle for 3 estrous circles. The Mouse Grimace Scale (MGS) was performed to evaluate CPP; blood flows of the upper genital tract, pelvic wall, and mesentery were used to assess hemodynamics in SPID mice; expressions of vascular endothelial growth factor (VEGF), angiopoietin-2 (Ang-2), and osteopontin (OPN) were measured by Western blot and immunochemistry. Results. Treatment with dose-dependent DZD significantly decreased the MGS scores, accelerated blood flows of the pelvis, and reduced expressions of VEGF, Ang-2, and OPN in the upper genital tract. Conclusions and Discussions. DZD was effective in relieving CPP and improving hemodynamics of the pelvic blood-stasis microenvironment in SPID mice. There was a relationship between CPP and the pelvic blood-stasis microenvironment. Furthermore, DZD might play a positive role in the anti-inflammatory process.

Insights into the paracrine effects of uterine natural killer cells.

Uterine natural killer (uNK) cells are recruited into the uterus during establishment of the implantation and placentation of the embryo, and are hypothesized to regulate uterine spiral artery remodeling and angiogenesis during the initial stages of pregnancy. Failures in uNK cell activation are linked to diseases associated with pregnancy. However, the manner in which these cells interact with the endometrium remain unknown. Therefore, this study investigated the paracrine effects of uNK cells on the gene expression profile of an endometrial epithelial and stromal cell co­culture system in vitro, using a microarray analysis. Results from reverse transcription­quantitative polymerase chain reaction and enzyme­linked immunosorbent assay experiments showed that soluble factors from uNK cells significantly alter endometrial gene expression. In conclusion, this study suggests that paracrine effects of uNK cells guide uNK cell proliferation, trophoblast migration, endometrial decidualization and angiogenesis, and maintain non­cytotoxicity of uNK cells.

Gene expression profiling of the paracrine effects of uterine natural killer cells on human endometrial epithelial cells.

The endometrium contains a population of immune cells that undergo changes during implantation and pregnancy. The majority of these cells are uterine natural killer (uNK) cells; however, it is unclear how these cells interact with endometrial epithelial cells. Therefore, we investigated the paracrine effects of the uNK cell-secretion medium on the gene expression profile of endometrial epithelial cells in vitro through microarray analysis. Our results, which were verified by qRT-PCR and western blot, revealed that soluble factors from uNK cells alter the gene expression profiles of epithelial cells. The upregulated genes included interleukin-15 (IL-15) and interleukin-15 receptor alpha (IL-15RA), which result in a loop that stimulates uNK cell proliferation. In addition, vascular endothelial growth factor C (VEGF-C) and chemokine (C-X-C motif) ligand 10 (CXCL-10) were also determined to be upregulated in epithelial cells, which suggests that uNK cells work synergistically with epithelial cells to support implantation and pregnancy. In addition, oriental herbal medicines have been used to treat infertility since ancient times; however, we failed to find that Zi Dan Yin can regulate these endometrial paracrine effects.
