Objective To investigate the effect of Zidan decoction containing serum on endometrial receptivity in uterine immunity environment,and then to discuss if it's effect on endometrial receptivity through its controlling the expression of cell factors which related to endometrial receptivity.Methods Mice's endometrium tissue samples and uterine Natural Killer (UNK) cells were obtained from pregnant mice on gd 4.5 days and gd 12.5 days.After endometrial glandular epithelial cells,endometrial stromal cells and UNK cells were separated through primary culture,epithelial cells and endometrial stromal cells at rate of 1 ∶ 1 a certain concentration UNK were mixed together and highly purified-cultured.Different concentrations of Zidan decoction was acted on the culture solution.FBS,black and aspirin control group were setup for contrast.The expression of LIF and VEGF which influenced by Zidan decoction in the immunity environment was assayed by Realtime-PCR.Results The expression of LIF and VEGF was significantly increased in the immunity environment of uterine (in 10% Zidan decoction group,10% aspirin group and 10% blank control group:LIF was 2.10±0.20,1.98±0.14,0.90±0.05 separately,and VEGF was 3.17±0.31,2.52±0.09,0.92±0.06respectively,P<0.05).Conclusion Zidan decoction could improve endometrial receptivity by increasing the expression of cell factor which related to endometrial receptivity with the help ofUNK paracrine.

OBJECTIVETo analyze the distribution characteristics of hirsutism and the law of meridian differentiation in polycystic ovarian syndrome (PCOS).
METHODSFor 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.
RESULTSA 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-(58.16%) and the stomach meridian of foot-(57.45%). According to:-, the high incidence of hirsutism (59.57%) resulted from the change ofand blood inmeridian. .
CONCLUSIONBlood plays the important role in the growth of body hair. Regarding theattribution, the incidence of hirsutism at theregions is higher than theregions. The occurrence of hirsutism is closely related toand blood changes in meridians. The conception vessel, the thoroughfare vessel, the liver meridian of foot-andmeridian act highly on the disease.

Objective :
To investigate the phenotype of amoxicillin ( AMX) unstable resistant Helicobacter pylori (Hp) evolving into AMX stable high level resistance and the detection of its mutated genes.
Methods :
Using the frozen Hp strain H390 as the starting strain,the clones resistant to AMX were continuously cultured on the medium with increasing AMX concentration,and the minimum inhibitory concentration ( MIC) of the resistant clones was detected.After frozen at -80 ℃ for 3 months,the drug resistance was stable according to whether the MIC de- creased after frozen storage. Genome sequencing analysis and efflux pump inhibition assay were performed on cloned H390r and parental strain H390 with the highest AMX MIC value,and gene mutations associated with the high level AMX resistance obtained by H390r were detected and identified.
Results :
Four AMX high level resistant clones were obtained by AMX screening with MICs of 12,32,64 and ≥ 256 mg / L ,respectively,and none of the MICs were altered after freezing at -80 ℃ . Compared to the parental strain H390,the AMX stable resistant clone H390r had mutations in several genes,including hefC encoding the RND efflux system,hopB and hopC encoding the pore proteins and ftsI encoding the penicillin binding protein ,which were associated with AMX resistance. H390r was substantially reduced in MIC to AMX in the presence of efflux pump inhibitors.
Conclusion
AMX can screen stable resistant clones from unstable resistant Hp.H390r had mutations in hefC,hopB,hopC,and ftsI asso- ciated with AMX resistance.These mutations may be the main reason why H390r acquired a stable high level of re- sistance to AMX.
