Objective To analyze the changes of energy metabolism-related proteins(enzymes) and transformation of energy metabolism in transplanted heart.Methods The hearts transplanted from Lewis to Wister rats as allografts and from Lewis to Lewis rats as isografts were used to estab- lish Ono model.The changes in proteins were observed by using proteomics technique and compared between allografts and isografts in the left ventricular myocardial tissues 2 and 8 weeks after heart transplantation.Peptide mass fingerprint map was obtained by using matrix-assisted laser desorption/ ionization time of flight mass spectrometry(MALDI-TOF-MS)and the matched proteins achieved by using Matrix Science software.Results Eighty proteins(enzymes)of total 65 differential proteins that regulated energy metabolism were identified in allografted hearts,which correlated to the Krebs cycle and electron transport system involving glycometabolism,fatty acid and branched-chain amino acids oxidation.Conclusion The energy metabolism in allografts heart was transformed:mitochondria function was decreased in Krebs cycle but enhanced in electron transport system and outer mitoehon- drial membrane permeability to ATP,accelerated in glycolysis and fatty acid oxidation,however, branched-chain amino acids oxidation were suppressed.

OBJECTIVETo search all studies that had been published in the world with regarding to the effectiveness of the extent of intralesional curettage and wide excision for recurrence rate and complications and comparative functional outcomes in patients with giant cell tumours (GCT) of the distal radius and analyze them which were in high quality by means of Meta analysis, in order to give some evidences for the choice of method dealing with giant cell tumors GCT in surgery.

METHODSCochrane central register of controlled trials(Issue 8 2014), PubMed(1970-01-01/2013-01-01), Ovid (1970-01-01/2013- 01-01), Elsevier (1970-01-01/2013-01-01), CNKI (1970-01-01/2013-01-01) were searched. Including intralesional curettage and wide excision were performed to treat giant cell tumors (GCTs) of the distal radius in the literatures, selecting on meet eligibility in the standard literatures underwent strict quality assessment. The Meta-analysis was performed with software RevMan5.0 from the Cochrane collaboration. Additionally, the analysis checked the heterogeneity of data. The effectiveness of the extent of intralesional curettage and wide excision for recurrence rate and complication in patients with giant cell tumours of the distal radius were evaluated and Odds Ratio was calculated.

RESULTSSeven relevant articles were identified involving total 163 cases. Among them, 92 cases were intralesional curettage (PMMA, n = 54; bone graft, n = 33; no PMMA or bone grafts, n = 5) and 71 cases were wide excision. The patients in the intralesional curettage group had a higher recurrence rate [OR = 3.87, 95% CI (1.42, 10.53)],especially for Campanacci grade 3 GCTs [OR = 10.12, 95% CI (1.57, 65.27)], yet fewer major complications [OR = 0.13, 95% CI (0.04, 0.40)] than the wide excision group. The use of PMMA versus bone graft did not affect the recur- rence rate [OR = 0.96, 95% CI (0.26, 3.56)]. By selecting the system evaluation of MSTS, the VAS and dynamometer, the result showed that the intralesional curettage group was equivalent or preferable to wide excision in terms of function rehabilitation.

CONCLUSIONBased on data obtained from the limited number of studies available, intralesional curettage appears to be moreappropriate for the treatment of local lesions (Grade 1 and 2) than Grade 3 GCTs of the distal radius. Moreover, PMMA was not additionally effective as an adjuvant, the intralesional curettage group was found to be equivalent or preferable to wide excision in terms of function rehabilitation.

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.

Objective　To analyze the clinicopathological features of angiolymphoid hyperplasia with eosinophilia (ALHE). Methods　The pathological specimens of 7 cases of ALHE collected in our department from 1950 to 1999 were sectioned, stained and observed. Results　There were 3 pathological characteristics in ALHE: ①massive hyperplasia of capillaries in the dermis; ②the endothelial cells proliferated and swelled, projecting into vascular cavity like tombstones; ③mixed infiltration of lymphocytes and eosinocytes in the vessels. Conclusion　ALHE is a disease with local benign proliferated vessels, whose etiology and pathogenesis is still unknown. It is necessary to grasp the pathological changes of ALHE to distinguish it from other diseases.

Conclusions The increase of age, the male and the extension of cardiopulmonary bypass time, the reduction of lymphocyte will increase the probability of pressure ulcer.

OBJECTIVETo search for a therapy of increasing clinical therapeutic effect on simple obesity with stomach and intestine excess-heat.

METHODSEighty-two cases of simple obesity with stomach and intestine excess-heat were randomly divided into group A (n=40) and group B (n=42). They were treated with electroacupuncture (EA), movable cupping plus acupoint catgut embedding, and simple EA, respectively. EA at Zhongwan (CV 12), Xiawan (CV 10) and Qihai (CV 6) were given in the two groups. And in the group A, acupoint catgut embedding and movable cupping at the Channels CV, GV, SP, ST and UB were added. The therapeutic effect, main symptoms, body mass index (BMI), waist circumference (WC), hip circumference (HC), and WHR were investigated.

RESULTSThe total effective rate was 90.0% in the group A, significantly better than 78.6% in the group B (P< 0. 01), with significant differences in decrease of body weight, BMI, WC, HC and main symptoms between the two groups (P<0.05, P<0.01).

CONCLUSIONAcupuncture, cupping plus acupoint catgut embedding therapy can increase therapeutic effect on simple obesity of stomach and intestine excess-heat type, and it is a better method for treatment of this disease.

OBJECTIVE: To measure the concentrations of soluble intercellular adhesion molecule-1 (s-ICAM-1), soluble vascular cell adhesion molecule-1 (s-VCAM-1), and von Willebrand factor (vWF) in the plasma of patients with rheumatic heart disease (RHD), and to provide basic theory for the mechanism of valvular and myocardial damage. METHODS: The consecutive patients with RHD (n=40) and healthy people (n=40) were chosen. All blood samples were taken from the peripheral veins. s-ICAM-1, s-VCAM-1 and vWF levels in all samples were measured by enzyme-linked immunosorbant assay. RESULTS: s-ICAM-1, s-VCAM-1 and vWF levels were significantly elevated in patients with RHD compared with healthy people (P < 0.01. The level of sICAM-1 was elevated in patients with atrial fibrillation compared with patients without atrial fibrillation. CONCLUSION The concentrations of s-ICAM-1, s-VCAM-1 and vWF levels were significantly elevated in patients with static rheumatic fever, which might be one of the pathogenic mechanisms of valvular damage, endothelial dysfunction, and myocardial damage in rheumatic heart disease.

OBJECTIVETo study the effects of early high fat diet on sugar metaboliam, insulin sensibility and pancreatic β cellularity in young rats.

METHODSSixty male weaned young rats were randomly fed with high fat diet (high fat group) and normal diet (control group). The body weight, viscus fattiness and fasting plasma glucose (FPG) were measured after 3, 6 and 9 weeks. Serum insulin level was measured with radioimmunoassay. The ultrastructure of pancreas was observed under an electricmicroscope.

RESULTSThe high fat group had significantly higher body weight and visceral fat weight than the control group after 3 weeks. There were no significant differences in the FPG level between the two groups at all time points. The levels of fasting insulin and HOMAIR in the high fat group were significantly higher than those in the control group after 3, 6 and 9 weeks (P<0.01). Dilation of rough endoplasmic reticulum and mild swelling of mitochondria of islet β-cells were observed in the high fat group after 6 weeks.

CONCLUSIONSEarly high fat diet may induce a reduction in insulin sensitivity and produce insulin resistance in young rats. Endoplasmic reticulum expansion in β-cells may be an early sign of β-cell damage due to obesity.
