OBJECTIVETo study the expression of centromere protein A (CENP-A) and its significance in hepatocellular carcinoma (HCC) and adjacent non-neoplastic liver tissue.

METHODSThe expression levels of CENP-A mRNA in 20 samples of HCC and adjacent non-neoplastic liver tissue were analyzed by reverse transcription-polymerase chain reaction (RT-PCR) and real-time quantitative polymerase chain reaction (qRT-PCR). Immunohistochemical study for CENP-A and p53 proteins was also performed on tissue microarrays containing 80 samples of HCC and adjacent liver tissue.

RESULTSThe expression level of CENP-A mRNA in HCC (0.64 +/- 0.18) was higher than that in adjacent non-neoplastic liver tissue (0.09 +/- 0.09) (t = 12.78, P < 0.01). Of the 80 samples of HCC, 57 cases (71.25%) and 60 cases (75%) expressed CENP-A and p53 proteins respectively. The positivity rates of CENP-A and p53 proteins in non-neoplastic liver tissue were 43.75% (35/80) and 16.25% (13/80) respectively. There was a statistically significant difference in CENP-A and p53 protein expression between HCC and non-neoplastic liver tissue (P < 0.01). The coincident rate between CENP-A and p53 expression was 88.75% (71/80). Expression of CENP-A protein showed a positive correlation with that of p53 protein (r = 0.57, P < 0.01).

CONCLUSIONThe over-expression of CENP-A occurs at transcriptional level and may be related to malignant proliferation of HCC via possible interaction with p53 gene.

OBJECTIVETo compare clinical results of treating Neer two- and three-part of proximal humeral fractures between anterolateral acromial approach and deltopectoral approach.

METHODSFrom January 2009 to December 2012, 49 patients with Neer two- and three-part of proximal humeral fractures were treated with locked plate fixation. In anterolateral acromial approach group, there were 22 patients including 9 males and 13 females with an average of (63.2±7.6) years old, while 27 patients in deltopectoral approach including 12 males and 15 females with an average of (62.9±7.0) years old. Operative time, blood loss during operation, fracture healing time and complications were observed and compared, postoperative Constant-Murley scoring and VAS scoring were applied for evaluate function of shoulder joint and pain at 3 months, 1 and 2 years respectively.

RESULTSAll patients were followed up from 24 to 41 months with an average of 34.5 months. Operative time, blood loss, fracture healing time in anterolateral acromial approach group was (68.20±7.04) min, (151.30±20.57) ml, (10.88±4.90) weeks respectively, and better than that of in deltopectoral approach group which was (75.81±13.70) min, (242.10±37.25) ml and (13.60±2.45) weeks. Three months after operation, Constant-Murley scoring and VAS score in anterolateral acromial approach group was 88.32±5.45, 0.41±0.63 and better that of in deltopectoral approach group which was 63.53±8.31, 1.65±1.02. There was no significant differences between two groups in Constant-Murley scoring and VAS score at 1 and 2 years after operation. Each group has one case occurred loss of length humerus head height, and there was 1 case with subacromial impingement, 1 case with bolt loose and 2 cases with delayed union in deltopectoral approach. No axillary nerve injury, humeral head necrosis and breakage of internal fixation occurred both of two groups.

CONCLUSIONBoth of anterolateral acromial approach and deltopectoral approach are effective in treating Neer two- and three-part of proximal humeral fractures, and can obtain excellent outcomes. Moreover, anterolateral acromial approach has advantage of less trauma, less blood loss, shorter operative time, rapid recovery of shoulder joint function and fracture.

OBJECTIVETo explore the pathogenesis of postburn intestinal mucosal injury in scalded rats.

METHODSThe rats inflicted with full thickness burn were employed as the model. The two-dimensional electrophoresis (2-DE) was employed to identify the down-regulating proteins from the differential proteins in scalded rats. Spot detection and matching were performed with Image Master 2D Elite. Mass spectrometry was performed on Bruker BIFLEX III TOF.

RESULTSThere are 34 points of proteins in intestinal mucosa in scalded rats which were down-regulated at 6 and 12 postburn hours. Among them 22 proteins were employed for the identification and analysis. Mitochondrial aconitase, alpha-propionyl -CoA carboxylase heavy chain A of F1-ATPase in rat liver, Troponin short-chain of hydroxyacyl-coenzyme A dehydrogenase, alpha-subunit of P-electronic transferring flavoprotein (ETF) were down-regulating proteins correlated with mitochondria in intestinal mucosa in severely scalded rats. Triosephosphate isomerase 1 and cytosolic epoxide hydrolase were down-regulating proteins participated in metabolism of scalded rats. Fibromodulin, dynein-like protein, Troponin-2 and myosin light chain 3 alkali (MLC) were down-regulating proteins correlated with cellular skeletal protein. Glucocorticoid-inducible protein, nuclear factor1-B2, BRCA1, transcriptive factor EB (estradiol benzoate), beta2 subunit of G-protein, N-methyl-D-aspartate receptor1 (NMDAR) were down-regulating proteins participated in postburn regulation of intestinal mucosa in scalded rats. T-cell receptor-V-delta 6 and Ig heavy chain V region protein 1 were down-regulating proteins correlated with the immunomodulation of intestinal mucosa in scalded rats.

CONCLUSIONThe down-regulating proteins of intestinal mucosa in scalded rats exhibited close relationship with mitochondria.
