Abstract: In order to improve the quality of reporting Chinese herbal medicine (CHM) trials, an elaborated checklist was developed according to the basic characteristics of traditional Chinese medicine (TCM) and on the basis of the Reporting Randomized Controlled Trials of Herbal Interventions: An Elaborated CONSORT Statement. This checklist adopted the 22 items of the Herbal CONSORT Statement with some necessary elaboration and modification in the detailed contents of 11 items, among which, the items of Participants, Intervention, Control group and Outcomes were elaborated and modified accordingly to adapt TCM characteristics. Since the design and reporting of trials on Chinese proprietary medicine and herbal decoctions are different in some aspects, the checklist provided two sets of elaborated item 4 (interventions). We hope that authors, journal editors and peer reviewers find this checklist instructive.

Qualitative research methods are becoming more and more important in medical research area. Some qualitative researches played important roles in the exploration and the spread of core ideas of Chinese medicine. The report of qualitative research should be transparent and credible according to the standardized report criterion. On the basis of 22 criteria, the Consolidated Criteria for Reporting Qualitative Research (COREQ) was developed and published in September 2007. This introduction to COREQ will be helpful to Chinese qualitative researchers and readers in the implementation of high quality of medical qualitative research in China.

BACKGROUND: The conical telescopic crown denture has a better long-term effect on dentition defects of few remaining teeth than the traditional removable denture. However, there are few studies to analyze the application of these two kinds of repair methods using the finite element method. OBJECTIVE: To compare the stress distribution of the isolated abutment tooth repaired using the conical telescopic crown denture and traditional removable denture. METHODS: Two-dimensional images of the mandible and dentition in healthy adults were scanned by CT. Three-dimensional finite element models of conical telescopic crown denture and traditional removable denture were established in the mandible only with the bilateral canines. Under the same vertical and oblique loadings, the maximum equivalent stress of the abutment, periodontal membrane or edentulous alveolar ridge was compared between two repair methods. RESULTS AND CONCLUSION: Under the vertical and oblique loadings, the total stress of abutment and periodontal membrane in the traditional removable denture was higher than that in the conical telescopic crown denture and the stress in the corresponding ring was concentrated obviously; the total stress of edentulous alveolar ridge in the conical telescopic crown denture was slightly larger than that in the traditional removable denture, but the stress was wel -distributed and concentrated in a smal area. Under the oblique loading, the total stress of abutment, periodontal membrane and edentulous alveolar ridge was higher than that under the vertical loading in these two dentures, and the stress was concentrated in the periodontal membrane of lingual neck, but the total stress in the traditional removable denture was larger, with a wider concentration range. These findings indicate that the stress on the supporting tissue of conical telescopic crown denture is more evenly distributed within a smal er range than that of traditional removable denture, and the former is more fit for the health of abutment, periodontal tissues and edentulous alveolar ridge.

BACKGROUND: Hydroxyapatite/β-tricalcium phosphate biphasic ceramic bone has good cel compatibility, but its mechanical properties are poor. OBJECTIVE: To construct chitosan/ or calcium alginate/biphasic ceramic bone scaffolds and to detect their mechanical properties and cytocompatibility. METHODS: Different concentrations of chitosan (2%, 4%, 7%, 10%) or calcium alginate (3%, 4%, 5%, 7%) were mixed with biphasic ceramic bone to prepare chitosan/biphasic ceramic bone scaffold and calcium alginate/biphasic ceramic bone scaffold. Their morphology and structure, coagulation time, anti-dissolution properties, shear force, compressive strength and cel compatibility were detected. RESULTS AND CONCLUSION: (1) Coagulation time: with the concentration increase, the initial and final setting time of these two kinds of composite scaffolds were prolonged to some extent. (2) Scanning electron microscopy: these two kinds of composite scaffolds showed porous microstructures with different pore sizes. (3) Anti-dissolution properties: the calcium alginate/biphasic ceramic bone scaffold (3%, 4%, 5%, 7%) and chitosan/biphasic ceramic bone scaffold (7%, 10%) had good anti-dissolution properties in the liquid. (4) Mechanical strength: with the concentration increase, the shear force and compressive strength of the calcium alginate/biphasic ceramic bone scaffold were reduced. (5) Cel compatibility: the cytotoxicity of chitosan/ or calcium alginate/biphasic ceramic bone scaffolds was graded as 0-1 or 2-3, respectively. These results show that the chitosan/biphasic ceramic bone scaffold has better mechanical properties and cel compatibility than the calcium alginate/biphasic ceramic bone scaffold.

To explore the effect of growth hormone releasing peptide (GHRP) on myocardial cell apoptosis in heart failure (HF) rats. Methods: Rat's HF model was established by the ligation of left anterior descending coronary artery induced ischemia. 40 male SD rats were randomly assigned into 4 groups: Normal control group, Sham operation group, HF group and GHRP treated HF group. n=10 in each group and the rats were fed for 4 weeks after the operation. Cardiac function was examined and myocardial cell morphology was observed; protein expressions of Smac/DIABL0 and Bcl-2 were measured by Western blot analysis; cell apoptosis was evaluated by FCM technique. The differences for above parameters were compared among groups to explore the effect of GHRP on myocardial cell apoptosis in HF rats. Results: Compared with HF group, GHRP treated HF group showed the less heart dilation, higher LVEF, lighter pathological changes in myocardial cells and decreased protein expression of Smac/DIABL0, all P<0.05. Bcl-2 level was lower in HF group than the other 3 groups, P<0.05. Compare with Normal control group, GHRP treated HF group had elevated Bcl-2 level, all P<0.05. Myocardial cell apoptosis index was different between HF group and GHRP treated HF group, P<0.05. Conclusion: The effect of GHRP on anti-HF should be via inhibiting myocardial cell apoptosis; the mechanism may partly be through promoting Bcl-2 protein expression and depressing Smac/DIABLO mediated mitochondrial pathway of apoptosis.
