Intrahepatic cholangiocarcinomas is a type of biliary epithelial cell carcinoma.Hepatolithiasis,viral hepatitis,primary sclerosing cholangitis,Caroli disease,parasitic infections are its risk factors.In recent years,the incidence of intrahepatic cholangiocarcinomas is gradually increased.Ultrasound,CT,MRI can be used to diagnose.The main way to treat intrahepatic cholangiocarcinomas is comprehensive treatment based on liver resection.There is still some controversy in liver transplantation.Adjuvant therapy will play a more and more important role in patients who unable to accept surgery.

Targeting cell apoptosis is currently the most promising therapy for cancer treatment. The BH3-only protein, which is a member of Bcl-2 family, can bind to the pro-survival members of the family and neutralize their functional activities to induce apoptosis (ie, to isolate pro-apoptotic members of the Bcl-2 family). BH3 mimetics, a kind of small molecule compounds, has the ability to mimic the BH3-only protein to induce apoptosis. The prototype of BH3 mimetics is ABT-737, who can selectively targets on BCL-XL, BCL-2 and BCL-W (but not MCL-1 and A1). ABT-263, a derivative of ABT-737, has a better performance of inducing apoptosis and inhibiting the growth of tumor in clinical trials. At this stage, some presumably BH3 mimetics has entered the clinical stage, while a large part of them is still being characterized and tested. Basing on the mechanism of BH3-only protein, this review summarize a variety of BH3 mimetics which have been widely recognized, and show the latest developments of newly diagnosed BH3 mimetics in the field.

ObjectiveAnalyze the mechanism of traditional Chinese medicine Salvia miltiorrhiza in treating coronary heart disease (CHD).MethodsThe animal experiment using actual research, namely the selection of rat isolated heart perfusion model, rat model of myocardial ischemia and ventricular tachycardia in rabbits model, then the effects of different animal groups in hemodynamics, coronary flow, serum superoxide dismutase (SOD) content, malondialdehyde (MDA) the results of the content.ResultsAfter treatment, the content of SOD was significantly increased and the content of MDA was significantly decreased in the treatment group, and the difference between the two groups was statistically significant (P<0.05).ConclusionTraditional chinese medicine Salvia miltiorrhiza has significant effect on the treatment of coronary heart disease, which is beneficial to the recovery of patients' condition, and is worthy of clinical application.

Cancer metastasis is multi-step process that requires cancer cells to jump through many hoops.The low-molecule-weight beparin (LMWH) has been reported effective for the treatment of metastasis to some extent, the mechanisms are proposed as anticoagulation, inhibition of heparanase, selectins, adhesion, angiogenesis mediated by the tumor cells, and the effects on cell cycle and apoptosis.

Gallstone ileus is a rare complication of cholelithiasis,and is common in older gallstones patients.It lacks the typical clinical presentation,so preoperative diagnosis is very difficult.The best diagnostic modality now is abdominal CT scan.Surgery is the most important and useful treatment.According to patient' s own situation,choose individualized surgical approach.Endoscopic,laparoscopic and other minimally invasive treatment are promising.With the development of related technologies,it maybe increased of the gollstone ileus treatment.

In order to improve the efficiency of protein spots detection, a fast detection method based on CUDA was proposed. Firstly, the parallel algorithms of the three most time-consuming parts in the protein spots detection algorithm: image preprocessing, coarse protein point detection and overlapping point segmentation were studied. Then, according to single instruction multiple threads executive model of CUDA to adopted data space strategy of separating two-dimensional (2D) images into blocks, various optimizing measures such as shared memory and 2D texture memory are adopted in this study. The results show that the operative efficiency of this method is obviously improved compared to CPU calculation. As the image size increased, this method makes more improvement in efficiency, such as for the image with the size of 2,048 x 2,048, the method of CPU needs 52,641 ms, but the GPU needs only 4,384 ms.

Objective To investigate the effects of methylthioadenosine phosphorylase (MTAP) on invasion and migration in breast cancer cells.Methods Human breast cancer cell line MCF-7 cells were treated with MTAPtargeted siRNA to diminish MTAP mRNA.MCF-7 cells proliferation was evaluated by cell counting kit-8,the analysis of cells invasion and migration was performed using Transwell chamber.The expressions of MTAP and matrix metalloproteinase 1 (MMP1) in cell extracts were detected by Western blotting.The experimental divided into blank contrd group,negative control group,MTAP-siRNA experimental group.Results The MCF-7 cells growth was promoted after knockdown the MTAP mRNA.MATP-siRNA experimental group 450 nm absorbance values at 24h,48 hand72 h of the control group were (112.3±11.9)％,(144.4±8.4)％,(169.3±9.4)％ respectively.Cell invasion analysis by Transwell chamber showed 570 nm absorbance values were 0.49 ± 0.06 (control),0.45 ± 0.07 (negative control) and 0.87 ± 0.07 (MTAP-siRNA) respectively.Cell migration analysis by Transwell chamber showed 570 nm absorbance values were 0.46 ± 0.06 (control),0.49 ± 0.08 (negative control)and 0.75 ± 0.07 (MTAP-siRNA) respectively.The expression of MMP1 in MCF-7 cells was upregulated after knockdown the MTAP mRNA.Conclusion The knockdown of MTAP in MCF-7 cell can increase the cells invasion and migration,and this may involve the the MMP1.

There are no intuitive and unified standards for selecting features in existing protein gel image point matching method, for which an analysis method based on similarity map is proposed. Firstly, the definition and generation methods of similarity map were presented. Secondly, trait and merits of features such as coordinate similarity, shape-context similarity and morphology similarity were analyzed using similarity map method. Finally, comprehensive utilization of multi-features named product-method which has a better effect than mean-method was proposed based on the results. Many experiments using different 2-DE gel images were carried out to prove the validity of similarity map and product-method. The results showed that similarity map could be used for intuitional, effective analysis of matching performance and to guide the selection and comprehensive utilization of multi-features.

Objective To improve the ethics review process and ethical standards,strengthen the implantation of ethical review of research involving human subject in our hospital.Methods Evaluating the review practice of research involving human subject in our hospital practices,learn and bring in the latest international experiences.Results As China's Ethical Committee is in its initial stage,the regulatory ability is still in defective and insufficient.A healthy and operable ethic review mechanism needs to be perfected gradually along with the practice.Conclusions In the aspect of improving the ethical review work of human subject research,some new methods and ideas were discussed.In addition to strengthen the current organizational system,we should clarify the elements of the review of different types of research and carry out multi level ethical trainings.The establishment of a unified,specific evaluative system,combined with this information platform is continuously monitoring the clinical study.This will ensure the human research projects comply with ethical requirements,and further promote the sustainable development of clinical research.
