Case report form (CRF) is a key document for data collection in clinical trials. A well-designed CRF is required for database construction, data accuracy, data query/cleaning, CRF completion and statistical analysis. A well-defined process or SOP should be in place for CRF design. Data collection should fully meet the demand of study protocol. The layout of CRF should be clear with well-structured fields and standard coding for fields.

Objective To examine the expression of toll-like receptor 2(TLR2)in peripheral blood monocytes and explore its association with disease stages and clinical manifestations and to explore the patho- genesis of rheumatoid arthritis(RA).Methods The expression of toll-like receptor 2 in peripheral blood monocytes from 47 RA patientis(27 in active stage and 20 in stable stage)and 18 normal individuals were de- tected by flowcytometry and RT-PCR.Results The expression of toll-like receptor 2 in peripheral blood monocytes in patients with active disease was significantly increased compared to non-active patients and nor- mal individuals,The expression was found to correlate with the Disease Active Score(DAS),serum C-reactive protein(CRP)level and the erythrocyte sedimentation rate(ESR),but not correlate with rheumatoid factor (RF)and the anti-cyclic citrullinated peptide(CCP)antibody.Conclusion The expression of toll-like recep- tor 2 in peripheral blood monocytes of patients with active RA is significantly increased.And the expression is correlated with disease activity index.The innate immune system is activated in patients with active disease. And the increased expression may promote the activities of monocytes.

Objective To determine the effects of~(99)Tc-MDP on joint inflammation and bone destruc- tion in collagen-induced arthritis(CIA)rats model and its effect on tumor necrosis factor alpha(TNF-?). Methods CIA was induced by immunization of male SD rats with an emulsion of collagen.~(99)Tc-MDP or placebo was intravenous infused to rats for 20 days.Joint inflammation was assessed by arthritis index.Lesions of bone were assessed based on the histological changes in ankle joints,radiographic analysis in hind paw with Larsen score.Systemic TNF-?level was measured by radioimmune assay.Results~(99)Tc-MDP suppressed joint swelling(P

The objective of this study is to combine troponin and indicators of cardiac acoustics for synthetically evaluating cardiac fatigue of rabbits, analyzing exercise-induced cardiac fatigue (EICF) and exercise-induced cardiac damage (EICD). New Zealand white rabbits were used to conduct a multi-step swimming experiments with load, reaching an exhaustive state for evaluating if the amplitude ratio of the first to second heart sound (S1/S2) and heart rate (HR) during the exhaustive exercise would decrease or not and if they would be recovered 24-48 h after exhaustive exercise. The experimental end point was to complete 3 times of exhaustions or death from exhaustion. Circulating troponin I (cTnI) were detected from all of the experimental rabbits at rest [(0. 02±0. 01) ng/mL], which, in general, indicated that there existed a physiological release of troponin. After the first exhaustive swim, cTnI of the rabbits increased. However, with 24-hour rest, S1/S2, HR, and cTnI of the tested rabbits all returned toward baseline levels, which meant that the experimental rabbits experienced a cardiac fatigue process. After repeated exhaustion, overloading phenomena were observed, which led to death in 3 out of 11 rabbits, indicating their cardiac damage; the troponin elevation under this condition could be interpreted by pathological release. Evaluation of myocardial damage can not be based on the troponin levels alone, but can only be based on a comprehensive analysis.

Heme oxygenase-1 (HO-1) is a cellular stress protein, and its expression plays an important regulatory role in a lot of physiological and pathological processes. Although the expression of HO-1 in most tissues of body is low, a number of clinical and pharmacological experiments have proved that many compounds can induce HO-1 expression. The increase of HO-1 expression is the result of regulating different signaling pathways and transcription factors, and this induction of HO-1 is suggested to be partially therapeutic efficacy of these compounds. This article summarizes some kinds of compounds in this field of research at home and abroad over the last 10 years, and provides a brief analysis of the mechanism.

OBJECTIVEThe aim of this study was to investigate the value of free anterolateral thigh myocutaneous flap (ALTMF) and computed tomography angiography (CTA) for the reconstruction of mouth-floor defects after the resection of middle-late stage carcinoma of the mouth floor.

METHODSSixteen cases of middle-late stage carcinomas of the mouth floor underwent radical resection, and mouth-floor and tongue defects were reconstructed with ALTMF. CTA was applied to plan the lateral circumflex femoral artery (LCFA) and its perforating vessel, which was verified during the operation.

RESULTSThe position of the perforating vessel in the operation was fully consistent with that designed by the preoperative CTA. All 16 flaps completely survived. The appearance and function of all cases were both satisfactory. All donor sites were primarily closed and healed without functional morbidity. During the follow-up period of 6-36 months, 15 cases survived with acceptable aesthetic and functional results in mouth floor and tongue reconstruction, except for 1 case (T4N2M0) that died of metastasis carcinoma 10 months after operation.

CONCLUSIONCTA can accurately locate the LCFA and artery perforator. Preoperative perforator planning using CTA in ALTMF transplantation is a reliable and useful method thatresults in safe operation with optimal outcome. The ALTMF is an ideal choice for the reconstruction of soft tissue defects after the resection of middle-late staie carcinoma of the mouth floor

Objective To evaluate the effect of team-based rehabilitation education on daily life ability of old patients having undergone operations on hip fractures.Methods Sixty elderly reconvalescents from operations on hip fractures were equally assigned into the intervention and control groups according to admission sequence:The intervention group received rehabilitation education by community nurses at months 1,3 and 6 and the control group were managed with convalesce at home.The two groups were compared in terms of daily life ability at the three time points. Result The daily life ability of the intervention group was better than that of the control group at all the three time points(P<0.05). Conclusion The team-based rehabilitation education is effective for the enhancement of daily life ability of old patients having undergone operations on hip fractures.
