Objective To study the ultra-structural features of interstitial cajal cells (ICC)in fetal enteron and then classify them.Methods Ultra-structural features of ICC in fetal enteron with spontaneous abortion or premature birth were detected under JEM-2000EX transmission electron microscope for the cause of fetal death, including two fetus specimens of a gestation 18 months and 28 months stained with lead nitrate and uranium acetate.Results ICC had a big oval karyon and a little of cytoplasm. ICC formed spindle or stellate cells with 2 to 5 long cell processes . From the esophagus to the terminal ileum ICC mostly had the same ultra-structural features, but with mitochondria and a well-developed endoplasmic reticulum and Golgi complex in the whole colon and the rectum , more than those of esophagus and small intestine. In the whole colon and rectum ICC had similar ultra-structural features. ICC also possessed an abundance of mitochondria and a well-developed endoplasmic reticulum and Golgi complex. ICC also possessed Caveloae lipid droplet with more electron dense and heterochromatin. Two types of ICC were identified under JEM-2000EX transmission electron microscope. One type was present from the esophagus to the terminal ileum and the other type was observed in the colon and rectum. The first type ICC in circular muscle layer was bipolar cells which extended to tapering processes in opposite directions. These processes rarely branched, and their appearance was similar to smooth muscle cells.Most of them ran parallel to the circular muscles . The second type of ICC in the myenteric plexus and longitudinal muscle layer was mostly multipolar and rarely bipolar cells with long processes. They showed an irregular appearance characterized by numerous short spike-like branches. Processes of multipolar cells extended in every direction and connected with each other. ICC nerve cells and smooth muscle cells were connected with gap-like junction, which was the main connection mode .Conclusions The ultra-structural features of ICC in fetal enteron varied with the diffe-rent locus and different tissue sheets in the enteron. The mitochondria and a well-developed endoplasmic reticulum and Golgi complex of the whole colon and rectum are more and more developed than that of esophagus and small intestine. Ultra-structural features of ICC will develop further with the gestational age. The gap- like junction among ICC nerve cell and smooth muscle cell are highly important for ICC to educe function.

In this study, OVA-induced asthma mice was taken as the model, and orally administered with different concentration of ethanol extracts of crude and processed Stemona tuberosa, in order to determine the cytokine level released from Th1 and Th2 in splenocytes. RT-PCR was carried out to determine the genetic expression of T-bet/GATA-3 in lung, and compare the differentiation between ethanol extracts of crude and processed S. tuberosa in therapeutic effect on asthma in mice. According to the results, compared with the crude samples, processed samples significantly increased the levels of inflammatory factor INF-gamma (P < 0.05) and decreased IL-5 (P < 0.05) in splenocytes. According to the RT-PCR results, the administration of processed samples could increase the ratio of T-bet/GATA-3 (P < 0.05). The experiment showed that ethanol extracts of both crude and processed S. tuberosa could treat asthma by regulating Th1/Th2 ratio, but processed samples showed more notable effect. This indicated that crude and processed S. tuberosa had significant pharmacological difference. Therefore, it was more rational to apply processed S. tuberosa in clinical treatment of asthma and chronic cough, which layed a foundation for further revealing the processing mechanism of S. tuberosa.

Objective To analyse the effects of serum estradiol levels during controlled ovarian hyperstimulation (COH) on the outcomes of in vitro fertilization and embryo transfer (IVF-ET). Methods The clinical data of 472 patients undergoing IVF-ET with GnRH analogues recombinant FSH long protocol were retrospectively analysed. The area under the curve (AUC) of estradiol (E2) level was calculated during COH, and patients were categorized into groups according to the percentile of AUC of E2(AUCE2) during COH. The general characteristics and parameters related to the outcomes of IVF-ET were compared among groups. Results The 10th percentile and 90th percentile of AUCE2 were 3 347.0 pmoL/L and 14 414.3 pmol/L, respectively. Four hundred and seventy-two patients were divided into lower reaction group (AUCE2 3 347.0 pmol/L, n=48), normal reaction group (14 414.3 pmol/L>AUCE2 > 3 347.0 pmol/L, n=376) and higher reaction group (AUCE2≥14 413.3 pmol/L, n=48). There was no significant difference in age, body mass index, baseline follicle stimulating hormone level, time of treatment with gonadotropin, endometrium thickness on day of transfer and embryos transferred(P>0.05). Compared with lower reaction group and normal reaction group, the number of oocytes per retrieval and number of embryos frozen were significantly larger(P<0.01) and the mild/severe ovarian hyperstimulation syndrome rate was significantly higher in higher reaction group(P<0.05). There was no significant difference in fertilization rate, cumulative embryo score, high-grade embryo rate, clinical pregnancy rate and implantation rate among groups (P> 0.05). Conclusion Sustained snpraphysiological serum E2 levels during the COH process do not adversely affect the quality of oocytes and embryos, clinical pregnancy rate and implantation rate to some extent in IVF-ET.

This is to report the screening, extracting and validating antitumor components and compounds from Stellera chamaejasme L. under the case of discrete distribution of active data. In this work, different components from Stellera chamaejasme L. were collected by HPD macroporous resin and polyamide resin column, and their antitumor activity on A549 were tested by MTT assay. Activity results indicate that activity of components at 30-39 min is more potent than that of Stellera chamaejasme L. extract, and the activity of components at 33.97 min is equivalent to positive drug, cis-platinum at 100 microg x mL(-1), but with totally different mode of action. Under the case of discrete activity, the weight analysis is capable of screening active components and compounds from natural products.

OBJECTIVETo explore effective pretreated methods for hydrosalpinx before frozen embryo transfer (FET).

METHODSA randomized controlled study was performed on 229 FET cycles of hydrosalpinx patients. They were assigned to two groups by random digit table, Group A (94 cases), Group B (89 cases), and Group C (46 cases). Patients in Group A received transvaginal aspiration of hydrosalpinx combined with auricular point sticking. Those in Group B received transvaginal aspiration of hydrosalpinx group. Those in Group C received no transvaginal aspiration of hydrosalpinx. Pregnancy outcomes of FET, endometrial and subendometrial blood flow distribution on the embryo transfer day were compared among the three groups.

RESULTSThere was no statistical difference in the endometrial thickness on FET day, the number of transfer embryos, the number of transferred good quality embryos among the three groups (P > 0.05). The clinical pregnancy rate and the embryo implantation rate were significantly higher in Group A than in Group C (P < 0.05), and the clinical pregnancy rate was significantly higher in Group A than in Group B (P < 0.05). The early abortion rate and the transfer cycle cancel rate were significantly lower in Group A than in Group C (P < 0.05). Type A endometrial and subendometrial blood flow distribution was dominant in Group A, which was significantly higher in Group A than the rest two groups (P < 0.05). Type A distribution rate was also significantly higher in Group B than in Group C (P < 0.05).

CONCLUSIONTransvaginal aspiration of hydrosalpinx combined with auricular point sticking before FET could improve the endometrial receptivity and improve outcomes of IVF.
