This paper is to report the development of a high-throughput in vitro system to screen hPXR/CAR mediated CYP2B6 drug inducers, and the application of it into the quick determination of induction activity toward CYP2B6 by various commonly used traditional Chinese medicines (TCMs) extract. Dual reporter gene assays were performed. The hPXR/CAR expression vectors and the reporter vector pGL3-CYP2B6-Luc involved in the distal and proximal promoters of CYP2B6 were co-transfected into HepG2 cells. Relative luciferase activities in cell lysate were analyzed after 48 h treatment of blank vehicle or drugs to determine the induction activity toward CYP2B6 by various commonly used TCMs extract. The positive hPXR/hCAR activators rifampicin and CITCO were applied to make sure that the reporter gene model was successfully established. Then 5 kinds of commonly used TCM extracts and 1 herbal compound were successfully investigated, some were found to activate hPXR or hCAR and therefore have the potential to induce CYP2B6 enzyme. This is the first domestic article to report the hCAR3-mediated CYP2B6 induction model and the establishment of a reporter gene system for hPXR/CAR-mediated CYP2B6 induction can be an effective and systemic in vitro method to investigate the drug inducers of CYP2B6 and to explain the mechanism involved.

Objective To research the visualization of congenital heart disease by three-dimensional echocardiographic(3DE) virtual endoscopy(VE) system. Methods Datasets.from 10 healthy children and 22 patients with congenital heart disease were collected (10 patients with atrial septal defects, 6 patients with ventricular septal defects and 6 patients with tetralogy of Fallot). 3DE heart models were reconstructed by virtual reality computing techniques and visualization in scientific computing techniques. The VE system was programmed under the C++ 6.0 language condition,the visualization toolkit (VTK) platform was employed to carry out the graphics and visualization utilities. The virtual eye can move along the navigation paths in the heart by manual camera movements. Results The VE can provide special information in aspects of intracardiac anatomy, The visible heart models show precisely complex anatomy structure and spatial relationships. 3DE intracardiac endoscopic imaging can thus be visualized and navigated successfully by the VE system. Conclusions 3DE VE is a new system for the visualization of congenital heart disease.

OBJECTIVE To estimate the distribution of pathogens of nosocomial infection in intensive care units,the sites where infections often taken place and the related antibiotic-resistance of bacteria.METHODS Various samples of bacteria from intensive care units have been examined by applying half-automatic analyzer ATB Expression,with bacteria inspecting cards and drug-sensitivity cards,all from Bio-Merieux,France.RESULTS Totally 153 strains of nosocomial pathogens have been found,where Acinebacter baumannii,fungi and Pseudomonas aeruginosa ranked top three,with rates of 32.0%,16.3%,and 15.0%,respectively.About 45.8% of pathogens were found in samples from the lower respiratory tract.Approximately 4.3% of A.baumannii showed drug-resistance to imipenem.However,more than 50.0% of A.baumannii presented its strong drug-resistance to rest of eight regular antibiotics.CONCLUSIONS A.baumannii is a dominating pathogen to cause nosocomial infection in intensive care units,and has shown strong multi-drug-resistance,which should incur high clinical attention.It comes to be crucial to highlight sanitization and sterilization operation,applying proper antibiotics in order to reduce appearance of bacteria with drug-resistance.

The Hospital Survey on Patient Safety Culture (HSOPSC) questionnaire was used for appraisal in a newly-built general hospital for all the nursing staff, and they were provided with a six-month safety culture training according to appraisal results.The training has elevated the positive response rate of the nursing staff towards all dimensions of patient safety culture, proving that scientific and reasonable safety culture training is conducive to nurses' perception of patient safety culture.

Objective To explore the diagnostic value of CT hypotonic colonography in carcinoma of colon.Methods A total of 55 cases who were diagnosed as ileus,abdomen mass or suspected colonic carcinoma clinically were undergone CT hypotonic clolonography in six years recently,in our hospital.Of them,CT data of 35 cases identified by pathology were analysed retrospectively.Results CT diagnosis was corresponded to the pathologic results in 34 cases .Of them,33 cases were colonic adenocarcinoma(1 case with intussusception of ileum-colon type),one case was abdominal multiple metastatic adenocarcinoma.One case with cecal inflammation and granulation tissues hyperplasia was misdiagnosed for colonic carcinoma by CT.21 of 35 cases were undergone colongraphy,of them,15 cases were diagnosed as colonic carcinoma,1 case was normal,colonographic failure occurred in one case and 4 cases were false negative.Conclusion Hypotonic water perfusion CT scan in the cases permitted under clinical condition(patient with ileus should be perfused with 3% meglumine diatrizoate) can display clearly the primary focus,the position and range of ileus,surrounding organ.It is more excellent than conventional CT and X-ray examination.

This paper proposed a rehabilitation training system with electromyography (sEMG) feedback for stroke patients based on ARM embedded system and LabVIEW. The system can achieve real-time acquisition, processing and dualview of multi-channel sEMGs and compute related sEMG parameters including iEMG, RMS, MPF and co-contraction ratio. The system was detected by clinical experiments and related inspection department. The result showed that the system is functional, interactive and in accordance with the relevant standards for medical devices so that it can fully satisfy the clinical demands. In addition, the system can help doctors to master the training state of the patient more effectively in a real-time and quantitative way that is direct to improve the training programs of stroke patients.

Objective To evaluate the efficacy of premedication of pronase and simethicone before upper gastrointestinal endoscopy. Methods A total of 4 690 patients undergoing upper gastrointestinal en?doscopy from January 2014 to November 2014 were recruited at gastrointestinal endoscopy center in Beijing Military General Hospital. All patients were randomized into 3 groups. The pronase plus simethicone group( n=1 602) took 40 ml mixed solution of pronase, sodium bicarbonate and simethicone orally 20 minutes before endoscopy. The simethicone group( n=1 548) took 40 ml simethicone orally 20 minutes before endoscopy. And the control group( n=1 540) took 10 ml lidocaine hydrochloride mucilage orally 5 minutes before endos?copy. The visibility during gastroscopy was observed. Results Each patient underwent gastroscopy, and no severe adverse event occurred during the procedure. The visibility of 82?3%( n=1 318) of the pronase plus simethicone group, 67?7%( n=1 048) of the simethicone group and 28?1% patients( n=432) of the control group respectively reached grade A or B. The visibility during gastroscopy in the pronase plus simethicone group was higher than that in the simethicone group(χ2=89?42, P=0?000) , while that in the simethicone group was higher than that of the control group(χ2=486?30, P=0?000). Conclusion Premedication of pronase and simethicone can improve the visibility during gastroscopy.

Objective To explore the expression of transient receptor potential channel 6(TRPC6)in human breast cancer cells, and to clarify the correlation of TRPC6 with the invasion potential of breast cancer cells. Methods The human breast cancer cell strains MCF-7 (hypo-invasion group)and MDA-MB-231 (hyper-invasion group)were cultured.The expressions of TRPC6 mRNA and protein in in two groups were detected by RT-PCR and Western blotting methods.Then the MDA-MB-231 cells were divided into control group and SKF96365 group, the effects of SKF96365 on the invasion ability of MDA-MB-231 cells invitro were explored by wound healing assay and Transwell experiment.Results The results of Western blotting and RT-PCR showed that the expression levels of TRPC6 mRNA and protein in MDA-MB-231 cells were higher than that in MCF-7 cells(P<0.05).The wound healing assay showed the numbers of migrating cells in 5,25 and 40μmol·L-1 SKF96365 groups (76.24±7.54, 45.33±4.50,25.12±1.57)were lower than those in control group (130.48±9.55)(P<0.05).The Transwell experiment results indicated that the invasiveness of MDA-MB-231 cells were inhibited significantly by SKF96365 compared with control group (P<0.05).Conclusion The invasion ability of human breast cancer MDA-MB-231 cells is promoted by upregulating the TRPC6 expression, which indicates that the TRPC6 may play role in the metastasis of human breast cancer.
