Electronic case report forms (eCRFs) instead of the traditional paper case report forms (pCRFs) are increasingly used by investigators and sponsors of clinical research. We include a total of 14 phase III studies (8 pCRF, 6 eCRF) to compare paper and electronic data documentation both quantitatively and qualitatively in clinical studies. The result suggests that adaptions of electronic data capture (EDC) in clinical trials have the advantages in optimization of data capture process, improvement of data quality and earlier clinical decision compared to paper-based methods. Furthermore, the successful implementation of EDC requires accouplements with corresponding data management processes and reallocation of resources.

Ninety soldiers stationed on this island were selected by random sampling , for whom questionnaires and interviews were designed, involving the influence factors of military operational ability .Results This island was a typical humid-hot environment, with high temperature , high humidity and high radiation .The physical fitness of soldiers declined obviously because of the typical humid-hot environment.The top five working environmental factors were high temperature , humidity, solar radiation, wind and seasonal drying .The top five personal factors were physical fatigue , overtraining, injury, mental fatigue and lack of sleep .Conclusion Considering the obviously decreased physical fitness of soldiers caused by the typical humid-hot environment , how to assess military combat effectiveness and how to determine whether the level of combat effectiveness can meet the actual needs of tropical combat , requires scientific indicators and criteria of evaluation .

Objective To investigate the effects of extracellular ATP on the expression of(Mi- crotubule associated proteins MAP-2)and the recovery of motor function after spinal cord injury in rats. Methods Six rats were selected randomly from 66 adult healthy Wistar rats as the normal control group,the rest animals were divided into two groups after contusion injury was performed by drop weight method with Allen impactor:Group A(ATP group)and Group B(control group),each group contained thirty rats.At days 1,3,7,14,and 28 after injury,the rats were killed,the expression of MAP-2 was detected with immunohistochemistry.The expression of MAP-2 in the adjacent area was quantitatively an- alyzed with a computer image analysis system.The recovery of motor function after spinal cord injury was assessed with improved Tarlov scores.Results The expression of MAP-2 was higher in Group A than in Group B after spinal cord injury in rats.Significant difference was revealed by the expression of MAP- 2 between the two groups at days 14 and 28 after injury(P

Objective To optimize the extraction method of salviae miltiorrhizae madix et rhizoma in Huoluo-Xiaoling granules. Methods According to the contents of Salvianolic acid B and Tanshinone Ⅱ A, the extraction method was established by comparing different solvents (water and 70% ethanol)and extracting modes (compound extraction and single herb extraction). Then orthogonal design was used to determine the optimum extraction method. Results Considering the contents of salvianolic acid B and tanshinone Ⅱ A, 70% ethanol extract was better than water extract and compound extraction was better than single herb extraction.The optimum extraction condition was 70% ethanol in eight times of the herbs weight, extracted for 1h by 3times. Conclusion The extraction method was simple and stable.

OBJECTIVE Hypoxia is associated with many complicated pathophysiological and biochemical processes that integrated and regulated via the key gene, protein and endogenous metabolite levels. Up to date, the exact molecular mechanism of hypoxia still remains unclear. In this work, we further explore the molecular mechanism of hypoxia and adaption to attenuate the damage in zebrafish model that have potential to resist hypoxic environment. METHODS The hypoxic zebrafish model was established in different concentration of oxygen with 3%,5%,10%,21% in water. The brain tissue was separated and the RNA-seq was used to identify the differentially expressed genes. The related endogenous metabolites profiles were obtained by LC-HDMS, and the multivariate statistics was applied to discover the important metabolites candidates in hypoxic zebrafish. The candidates were searched in HMDB, KEGG and Lipid Maps databases. RESULTS The zebrafish hypoxic model was successfully constructed via the different concentration of oxygen, temperature and hypoxic time. The activities of the related hypoxic metabolic enzymes and factors including HIF-1a, actate dehydrogenase (LDH) and citrate synthase (CS) were evaluated. Significant differences (P<0.05 and fold change >2) in the expression of 422 genes were observed between the normal and 3% hypoxic model. Among them, 201 genes increased depended on the lower concentration of oxygen. 53 metabolites were identified that had significant difference between the hypoxia and control groups (P<0.05, fold change>1.5 and VIP>1.5). The ten key metabolites were increased gradually while six compounds were decreased. The endogenous hypoxic metabolites of phenylalanine, D-glucosamine-6P and several important lipids with the relevant hub genes had similar change in hypoxic model. In addition, the metabolic pathways of phenylalanine, glutamine and glycolipid were influenced in both the levels of genes and metabolites. CONCLUSION The up- regulation of phenylalanine, D- glucosamine- 6P and lipid may have further understanding of protective effect in hypoxia. Our data provided an insight to further reveal the hypoxia and adaptation mechanism.

To study the anti-coagulant effect and influence of danggui Sini decoction (DSD) on rat's plasma endogenous metabolites by animal experiment and ¹H-NMR based metabolomics method. After intragastric administration of Danggui Sini Decoction for 7 days, Plasma thrombin time (TT) was measured. Rat plasma metabolic fingerprint in two groups was analyzed using ¹H-NMR, based on which the principal component analysis( PCA) and orthogonal partial least-squares discriminant analysis(OPLS-DA) models for metabonomic analysis. Potential biomarkers were screened by using variable importance in the projection (VIP) and T test. DSD could prolong TT of the rat significantly (P < 0.05). Compared with control group, six kinds of endogenous metabolites in DSD group change significantly (P < 0.05), among which isobutyrate, carnitine and phenylalanine content had an upward trend (P < 0.01) and lysine, Histidine and cholesterol content had a downward trend (P < 0.05). It is likely that carnitine, phenylalanine, Histidine and cholesterol are the potential metabolic markers in the anti-coagulant process and DSD affects the platelet aggregation and the expression of tissue factor and fiber protease by regulating the energy, amino acid and lipid metabolism.
