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.

Objective To summarize the clinical experience in treatment of the Lisfranc joint injury with open reduction and internal fixation at early stage. Methods Twelve patients ( including ten males and two females at average age of 34 years) with early stage Lisfranc joint injury received open reduction and screw/wire fixation from 2005 to 2010. According to the Myerson classification, there were two patients with type A, eight with type B and two with type C. All the patients received open reduction and internal fixation with screw or Kirschner wire within 17 days after injury. The post-operative function was estimated by mid-foot scoring scale of AOFAS. X-ray and CT scan were used in radiography estimation. Results All the patients were followed up for average 33 months ( range, 6-60 months). The mean score of post-operative mid-foot scoring scale of AOFAS was 74.5 points ( range, 53-96 points), with excellent result in eight patients, good in two and fair in two. The anatomical reduction was observed in eight patients and all the patients obtained bony union according to the results of X-ray and CT scan.There was no any complication found.Conclusions Open reduction and internal fixation is a good choice for the treatment of Lisfranc joint injury at early stage. A preoperative comprehensive analysis combined with clinical X-ray and CT scan is necessary.

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.

AIM: To evaluate the efficacy and safety of two different surgical techniques on congenital cataract on children.METHODS: Twenty-two children (1-3 years old) with congenital cataract were randomly divided into two groups (group A and group B). With group A (10 patients, 20 eyes), we applied 23-gauge (23G) trans corneal limbus vitrectomy system to complete lens cortex gettering, posterior capsulotomy and anterior vitrectomy；With group B (12 patients, 24 eyes), we used the phacoemulsification I/A to complete lens cortex gettering, and performed anterior vitrectomy with anterior vitreous cutting instrument. After that, the differences in intraoperative and postoperative complications between two groups were compared. RESULTS：In group A, the width of corneal limbal incision was 0.6mm, the incision was self-sealing, and the anterior chamber was stable and iris did not prolapse during the surgery. In group B, the width of corneal limbal incision was 3mm, anterior chamber was unstable and intraoperative iris prolapse occurred in 14 eyes (58%). And the incision need to be stitched up after surgery. In the postoperative follow-up of 6-24 months (an average of 14 months), we found that corneal neovascularization did not occur in group A, while in group B, corneal neovascularization occurred in four eyes (17%); Other complications, such as posterior capsular opacification，retinal detachment, glaucoma, hypotony or endophthalmitis did not occur in either group.CONCLUSION: The 23G trans corneal limbus vitrectomy system used in pediatric cataract surgery is safer and more effective than phacoemulsification I/A. It is promising in treatment of congenital cataract on children.

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.
