Methods According to the relevant management regulations, guidelines, and other relevant documents of national and international clinical research data,“Questionnaire for Research Data Management Assessment of Chinese Chronic Disease Prevention” was designed. The questionnaires were used in 10 clinical topics during the on-site inspection survey, and 20 valid questionnaires were retrieved and analyzed statistically. Results 50-60 percentage of subjects in data management and statistics were performed by the third party;70 percentage of subjects were performed by their own central monitoring;50 percentage of the subjects adopted a cooperative manner with others to develop appropriate data management systems;7 centers had system and plan for data management;Data management was carried out;implementation degree of training, database, CRF tracing, and others 7 aspects was low. Conclusion Improving the quality of data management of TCM clinical research still needs to be perfected from many aspects, and quality mode of large-scale clinical trials should be improved.

Background Traditional Chinese medicine (TCM), especially herbal medicine, has been widely used in China and now is also being increasingly used in other countries for the treatment of cardiovascular diseases. Although many studies have demonstrated that certain Chinese herbal products are effective and safe for the treatment of cardiovascular diseases, most of these lack sufficient quality. Therefore, large randomized clinical trials and further scientific research to determine its safety, effectiveness are necessary.QiShen YiQi Dripping Pills (QSYQDP) is a herbal preparation clinically used in the treatment and prevention of coronary artery disease. Preliminary observations have shown its safety and effectiveness. Methods/Design This randomized, controlled trial will recruit 3600 patients with a history of myocardial infarction. Patients will be randomized into two groups by a Centr-Randomized System. One group receives QSYQDP, the other group receive aspirin. This trial protocol will describe eligibility criteria, detailed information on the treatment definition, blinding, endpoints, statistical methods, sample size determination, data management, legal aspects, and the current status of the trial. Discussion This trial is one of the first randomized, controlled clinical trial to evaluate the efficacy and safety of traditional Chinese herbal medicine in the treatment and secondary prevention of coronary artery disease. The results of this study should help to define the role of TCM in modern medical care, as well as to provide the management strategy for CAD patients in China and other countries.

A field investigation was conducted on the floral syndrome and breeding system of Corydalis edulis located in natural populations in campus of Anhui Normal University by out-crossing index, pollen-ovule ratio, artificial pollination and bagging experiment. The results showed that the plant was in bloom from March to May and flowering span among populations was 72 days. The flowering span for a raceme was 14-24 days. The life span of one single flower was approximately 5-10 days. Spatial positioning of stigma and anthers were spatially desperation on the day of anthesis. The filaments were shorter than the styles through pollen vitality and stigma receptivity experiments. A self-pollination breeding system was reflected by OCI 3, pollinators were required sometimes; A complex cross bred was indicated by P/O = 857.14, combined with the results of the bagging and artificial pollination experiment, the breeding system of C. edulis was mixed with self-pollination and outcrossing. The special floral structure and pests destroying may have a certain impact on seed-set rate.

ObjectiveTo compare the differences in clinical characteristics between kidney deficiency and stasis obstruction syndrome and damp-heat stasis obstruction syndrome in patients with ankylosing spondylitis （AS）， thereby providing reference for clinical differentiation and treatment. MethodsThe clinical data of 2339 patients with AS were collected， including 1075 cases of kidney deficiency and stasis obstruction syndrome and 1264 cases of damp-heat stasis obstruction syndrome. The basic information including age， gender， course of disease， history of ophthalmia， family history and human leukocyte antigen B27 （HLA-B27） positive history， Bath ankylosing spondylitis disease activity index （BASDAI） score， Bath ankylosing spondylitis functional index （BASFI） score， Bath ankylosing spondylitis measurement index （BASMI） score， Depression Anxiety Stress Scale 21 （DASS-21） score， single symptom score in terms of spinal pain， peripheral joint pain， tendon tenderness， morning stiffness degree and morning stiffness time， patient-reported outcomes including patient global assessment （PGA） score， chronic disease therapy function-fatigue scale （FACIT-F） score and night pain visual analog scale （VAS） score， laboratory indicators including serum C-reactive protein （CRP） and erythrocyte sedimentation rate （ESR）， and CT grading of sacroiliitis were measured and compared between groups. ResultsPatients with kidney deficiency and stasis obstruction syndrome were older and had a longer course of disease （P＜0.01）. The BASDAI， BASFI and BASMI scores of the patients with kidney deficiency and stasis obstruction syndrome were 3.84±1.79， 2.78±2.00 and 3.42±2.36， respectively， while those in patients with damp-heat stasis obstruction syndrome were 4.30±1.99， 3.43±2.12， and 2.92±1.76. The BASDAI score， BASFI score， PGA score， FACIT-F score， spinal pain score， peripheral arthralgia score， tendon tenderness score， morning stiffness degree score， depression score， anxiety score， and stress score in patients with damp-heat stasis obstruction syndrome were all higher than those with kidney deficiency and stasis obstruction syndrome， with longer duration of morning stiffness and higher CRP （P＜0.05 or P＜0.01）. BASMI score and night pain VAS score were more higher in patients with kidney deficiency and stasis obstruction syndrome （P＜0.01）. There was no significant difference in the ESR level and CT grading of the sacroiliac joint between the two groups （P＞0.05）. ConclusionAS patients with kidney deficiency and stasis obstruction syndrome have poorer spinal mobility， while those with damp-heat stasis obstruction syndrome have higher disease activity， poorer physical function， and are more prone to adverse psychological reactions.
