Objective To evaluate the effect of wild feces detection in Oncomelania hupensis environments on the surveil?lance of infection source of schistosomiasis,and find the weakness in schistosomiasis control in Hubei Province,so as to put for?ward the targeted strategies and measures. Methods Four environments with O. hupensis snails in endemic areas of Hubei Provinces,where human and livestock often haunted,were selected according to the river systems,namely the Juzhanghe River beach in Jingzhou City,Changjiang River beach in Jiayu County,Hanbei River beach in Tianmen City,and Changshou River beach in Zhongxiang City,then the snail survey and wild feces detection were implemented in the selected environments. Re?sults There were O. hupensis snails,livestock,wild feces of cattle or sheep as well as positive cattle feces found in all the 4 environments,and the positive rate of schistosome miracidium incubation was 47.62%. Conclusion The schistosome miracidi?um positive rate of wild feces of cattle is high in the environments with snails in endemic areas of Hubei Province ,which has high risk for schistosomiasis transmission.

Although traditional Chinese medicine (TCM) shows its effectiveness undoubtedly in clinical practice, the deficiency in objective assessment methods is yet a bottleneck which has restricted its development of modernization and internationalization. On the basis of clinical experiences, the authors discussed the title cutting from current situation and tendency, and expanded gradually. It is concluded that by aiming directly at problems and referring to the principle and methods of evidence-based medicine (EBM), using rationally the design in clinical practice and combined with individualization and standardization should be a feasible way for TCM clinical therapeutic effect assessment.

Objective To optimize the extraction process of anti-hepatic fibrosis water-soluble component from Carthamus tinctorius L. via the orthogonal method. Methods The influences of type and content of solvent,extraction time,and extraction frequency on processing were investigated by assessing the content of hydroxysafflor yellow A,yield of extraction and anti-hepatic fibrosis potency via the high performance liquid chromatography and enzyme-linked immunosorbent assay by L9(3)4 orthogonal test. Results The optimum extracting condition for the anti-hepatic fibrosis water-soluble component from carthamus tinctorius L. was as follows: extracting with 10 times the volume of 10% ethanol for twice, 0. 5 h in each. Conclusion The process is scientific and feasible, which serves as a guideline for the production of the anti-hepatic fibrosis water-soluble components.

Objective To observe the effect of external use of Curcuma oil on the hyperplasia of mammary glands in rats and explore the mechanism. Methods Sixty female Wistar rats were randomly divided into following groups:normal con-trol group, model control group, Sanjierubi plaster group, low-, medium- and high-dose curcuma oil emulsion groups ( n=10 each).The models of hyperplasia of mammary glands were established by intramuscular injection of estradiol benzoate and proges-terone into the medial part of the rat hind limb.Different doses of medicines were given for 4 consecutive weeks.Enzyme-linked im-munosorbent assay, HE staining and immunohistochemistry were used to investigate the action mechanism of curcuma oil emulsion against mammary gland hyperplasia. Results Curcuma oil emulsion had preventive and therapeutic effects on the hyperplasia of mammary glands.The diameter of breasts was significantly reduced, the body weight restored, serum estradiol, follicle-stimulating hormone and prolactin levels profoundly decreased, progesterone, testosterone and luteinizing hormone levels markedly increased and the number and diameter of lobular acini obviously reduced in high-dose curcuma oil emulsion group when compared with those in model control group (P<0.05 or P<0.01). Conclusion Curcuma oil emulsion can remarkably improve the disturb-ance of serum hormones and inhibit the occurrence of hyperplasia of mammary glands.

Objective To determine the probability of identification of differential expression of biliary proteins induced by cholangiocarcinoma using 2D-DIGE. Methods Bile was obtained from 12patients with obstructive jaundice (including 6 cases of cholangiocarcinoma and 6 of cholelithiasis).Each sample was labeled with three different CyDyes (y3,Cy5,Cy2) including one internal standard,pooled from all the samples, and separated with 2-D DIGE in triplicate experiments. MALDI-TOF-MS and bioinformatics were adopted to identify and elucidate the significance of differentially expressed proteins in bile induced by cholangiocarcinoma. Results 55 matched protein spots differences in abundance were detected with statistical variance of two groups(Average Volum Ratio ≥1.5, t-test, P＜0. 05). Among these proteins, 13 PMF were obtained by MALDI-TOF-MS analysis. Eight proteins were identified by searching a protein database. Conclusion The differentially displayed proteomes between the pathological bile obtained from benign and malignant obstructive jaundice indicates the potential application of 2D-DIGE to identify the biomarker of cholangiocarcinoma.

Aim To study the mechanism of action of the new derivative of podophyllotoxin(LN-13)in indu-cing the apoptosis of K562/A02 cells.Methods The MTT method was taken to detect the inhibition of LN-13 and VP-16 on K562/A02 proliferation and inhibi-tion rate and IC50 values were obtained 48 hours later. The K562/A02 cell morphological change induced by LN-13 were observed through Hochest33342 and PI staining after 48 hours later.Flow cytometry was taken to detect the apoptosis of K562/A02 cells induced by LN-13.The reverse transcription-polymerase chain re-action was taken to detect the Bcl-2,Bax,caspase-3 and mdr-1 mRNA expression.The expression of P-gp was detected by Western blot.Results The growth of K562 /A02 cells was obviously inhibited by LN-13 when IC50 value was 3.32 μmol · L-1 .LN-13 could obviously induced cell apoptosis observed by Ho-chest33342 and PI staining.Flow cytometry detection showed that LN-13(2,4,8 μmol·L-1 )could induce cell apoptosis and apoptosis ratio reached 15.0%, 48.0%,68.96%,respectively.The reverse transcrip-tion-polymerase chain reaction showed that LN-13 in-creased the Bax and Caspase-3 mRNA expression,and meanwhile the expression of mdr-1 mRNA decreased. Western blot showed that P-gp expression was de-creased as the LN-13 dose increased.The data were significantly different from those of control group.Con-clusion Podophyllotoxin derivative LN-13 can induce the apoptosis of K562 /A02 cells,which may be close-ly-related to regulating P-gp expression and apoptosis related gene mRNA expression.
