In the process of scientific research management informationization,some critical questions are proposed.It is necessary to investigate comprehensively the information construction,and make a plan with overall point of view.Meanwhile,it is of importance to think highly of the standardization and practicability of information,keep good coordination and communication with all persons involved in the information construction,maintain and renew the information duly,draw the assistance from foreign technical support,and utilize the achievements of the informationization to improve the management.

It is important to protect the subjects'right of informed consent in biomedicine research.In this study,we focused on discussing how to protect the subjects' right of informed consent,including the perspectives of leg principles,the obligations of the researchers,the functions of Institutional Review Board,and the self-protection of subjects.

This paper discusses project management of translational medicine in several important aspects:scientific planning,platform constructing,team building,process management,technology transfer,protection of intellectual property rights,supervision on ethics,and project funding system of the institutions.

for the determination of aconitine, mesaconitine and hypaconitine in root tuber of sevral species of Aconitum plants and related proprietary medicines. With the use of the optimized instrumental conditions and the Multiple Reaction Monitoring (MRM) technique, good linearity was obtained for the alkaloids in concentrations ranged from 0.5 to 40 mg/L. The method was applied to the analysis of 14 samples of various species of Aconitum plants and 10 different proprietary medicine samples

Objective To screen primers used in polymerase chain reaction (PCR) for detecting Trichomonas vaginalis. Methods Three pairs of PCR primer reported in the literatures (TVA5-TVA6, TV1-TV2 and TVK3-TVK7) were screened. For each PCR, four components, including primers, Mg2+, dNTPs and Taq polymerase, were optimized using Taguchi methods to determine the optimal PCR conditions. With the optimal conditions, the sensitivities of three PCR were compared. Vaginal swabs were collected to detect Trichomonas vaginalis by culture and PCR, and the PCR with highest sensitivity was evaluated. Results All three PCR were of high specificity, and the PCR with primers of TVK3-TVK7 had the highest sensitivity. Of 25 clinical vaginal swabs, T. vaginalis was detected in 7 samples by the culture, however, it was detected in 8 samples by the PCR. All culture-positive samples were also positive by PCR. Conclusions The PCR with the primers of TVK3-TVK7 is highly sensitive and specific, which could be useful to detect T. vaginalis in vaginal swab samples.

Purpose　The aim is to find out an effective preventing influenza immune preparation. Methods　Egg yolk immune solution of anti-influenza virus(FM1 stem) was prepared from egg of the hens that had been successfully immunized with influenza virus (FM1 stem). Its effects of anti-virus were observed through animal experiment.Results　When the mice of control group began to die the average daily drink quantity of the mice of normal saline control group, egg yolk immune solution control group, immediate preventive group was (3.06±0.86), (2.93±1.47) and (3.99±0.21)ml(P＜0.05)respectively. The average body weights of the mice of these three groups were (15.85±2.70),(14.58±1.92) and (18.27±1.71)g(P＜0.05)respectively. Their mortality was separately 53.84%,69.23% and 3.84%(P＜0.01). The antibody positive rate of survived mice′s serum (1∶10 diluted) was separately 100%, 100% and 0%(P＜0.01). Conclusion　The anti-virus effects of egg yolk immune solution of anti-influenza virus was powerful. The result of preventing mice′s influenza was remarkable.

Since smart phones have been developed, significant advances in the function of mobile phone due to the development of software, hardware and accessories have been reached. Till now, smart phones have been engaged in daily life with an increasing impact. As a new medical model, mobile phone medicine is emerging and has found wide spread applications in medicine, especially in diagnosing, monitoring and screening various diseases. In addition, mo bile phone medical application shows great potential trend to improve healthcare in resource-limited regions due to its advantageous features of portability and information communication capability. Nowadays, the scientific and technological issues related to mobile phone medicine have attracted worldwide attention. In this review, we summarize state-of-the-art advances of mobile phone medicine with focus on its diagnostics applications in order to expand the fields of their applications and promote healthcare informatization.

Objective To investigate the value of double-balloon endoscopy (DBE) and multi-slice CT enteroclysis (MSCTE) in diagnosis of Crohn's disease (CD) in small intestine. Methods DBE and MSCTE were performed in 71 patients with suspected Crohn's disease in small intestine. The two methods were compared in terms of diagnosis, extents of disease, existance of complications and activity of the disease according to the pathologic findings and the outcome of follow-up. Results The diagnostic yields of DBE and MSCTE were comparable with no significant difference (χ2=2.29, P> 0.05). The positive and negative likelihood ratios were 22.5 and 0. 022 in DBE respectively, and were 1.6 and 0. 240 in MSCTE respectively. The results of DBE was consistent with MSCTE in diagnosis of mild bowel stenosis, but was inconsistent with MSCTE in diagnosis of moderate-severe bowel stenosis (χ2=11.298, P=0.001). The concordance of two methods in diagnosis of disease activity was 95.8%. Conclusions The first choice in diagnosis of small bowel CD is DBE. The combination of two methods will be helpful in diagnosis and evaluation of CD severity.

Objective To develop a gene chip for the detection of pathogens causing genital ulcer diseases (GUDs). Methods Specific probes of 4 different pathogens were designed and synthesized. Gene chip was prepared by blotting the probes onto specially treated glass slides with the use of a robotics. Target genes of standard strains for the 4 different pathogens and the clinical specimens were amplified by PCR with Cy5 fluorescence labeled primers. The labeled amplicons were hybridized with gene chips, and then scanned and analyzed using computer software. Results The fluorescence signal for specific pathogen could be found in the gene chip, illustrating that one specific fluorescence signal denoted a single pathogen, and the combination of different signals denoted the corresponding co-existence of pathogens. Examination of 40 clinical specimens obtained from 40 patients with genital ulcers with gene chip was in good concordance with dark-field microscopy plus PCR or HSV culture plus PCR, showing Kappa values of 0.882 and 0.947, respectively. In addition, mixed infections were detected in 2 specimens. Conclusion Gene chip is a sensitive method with a reliable result and it can detect multiple infections simultaneously.
