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 investigate the protective effect of six Kaixin San formulas on simulated cells model of depression, Alzheimer's disease and Parkinson's disease.
METHODThe in vitro simulated cells model of depression, Alzheimer's disease and Parkinson's disease was established by injuring SH-SY5Y cells with corticosterone (0.4 mmol x L(-1)) , injuring PC12 cells with neurotoxic amyloid peptide (Abeta25-35) (20 micromol x L(-1)) and injuring SH-SY5Y cells with 1-methyl-4-phenylpyridinium ion (MPP+) (250 micromol x L(-1)). The cell survival rate was assayed with MTT method and the degree of cell injury was detected with LDH.
RESULT100, 500 mg x L(-1) Dingzhixiao Wan prepared as mentioned in Beiji Qianjin Yaofang could significantly increase the survival ratio of SH-SY5Y cells injured by corticosterone and reduce LDH concentration released. All of the Kaixin San formulas could significantly increase the survival ratio of PC12 cells injured by Abeta25-35 and reduce LDH concentration released. Particularly, Kaixin San (10, 100, 500 mg L(-1)) prepared as mentioned in Beiji Qianjin Yaofang shown the best effect. And 500 mg x L(-1) Fushen Wan prepared as mentioned in Gujin Luyan could significantly increase survival ratio of SH-SY5Y cell injured by MPP and reduce LDH concentration released.
CONCLUSIONDingzhixiao Wan prepared as mentioned in Beiji Qianjin Yaofang could protect corticosterone-induced SH-SY5Ycells injury, showing a potential antidepressant effect. All of the six Kaixin San formulas could protect Abeta25-35-induced PC12 cells injury, but Kaixin San prepared as mentioned in Beiji Qianjin Yaofang shown the best potential effect for Alzheimer's disease. Fushen Wan prepared as mentioned in Gujin Luyan could protect MPP(+)-induced SH-SY5Y cells injury to some extent.
