Objective: To investigate the expressions of tumor stem cell markers EpCAM (epithelial cell adhesion molecule) and CD133 proteins in human primary hepatocellular carcinoma, and to explore their relationships with clinicopathological features and the prognosis. Methods: The expressions of EpCAM and CD133 in liver cancer tissues from 70 patients with primary hepatocellular carcinoma were detected by immunohistochemistry. The survival analysis was performed, and the correlations of EpCAM and CD133 with the clinicopathological features and the prognosis were analyzed using SPSS (Statistical Package for the Social Sciences) software package 17.0. Results: The positive rates of CD133 and EpCAM proteins were both significantly higher in liver cancer tissues than those in paracancerous tissues (P < 0.01). Aberrant expression of CD133 was observed in the paracancerous tissues. The positive expression of CD133 was positively correlated with vascular invasion in liver cancer tissues (P < 0.05). The expression level of EpCAM in poorly differentiated liver cancer with vascular invasion in patients with preoperative AFP level over 400 ng/mL was significantly higher (P < 0.05). There was a positive correlation between EpCAM expression and CD133 expression (P < 0.01). The survival of patients with strongly positive expression of CD133 (or EpCAM) was inferior to that of patients with moderately-weakly positive expression of CD133 (or EpCAM). In the subgroup of preoperative AFP level over 400 ng/mL, the survival of patients with moderately-strongly positive expression of EpCAM was inferior to that of patients with weakly positive expression of EpCAM. The factors of the number of tumors, preoperative AFP level, tumor capsule and CD133 expression were independent predictors of prognosis of primary hepatocellular carcinoma. Conclusion: CD133 and EpCAM may be associated with the progression of primary hepatocellular carcinoma, and their high expression may indicate poor prognosis, thus it is suggested EpCAM (+) AFP (+) primary hepatocellular carcinoma subtype has features of high-grade malignancy.

Objective To investigate the different expression pattern of Src-homology2 domain phosphatase (SHP)-1 and SHP-2 in human papiilomavirus (HPV)6/11 infected condyloma acuminatum (CA) and the significance of the difference. Methods HPV6/11 related CA cases were diagnosed by in situ hybridization. The expression and distribution of SHP-1 and SHP-2 were examined by SP immunohistochemistry technique in skin samples from 40 HPV 6/11 positive CA cases and 20 healthy control (foreskins). Results The positive rates of SHP-1 and SHP-2 were 80% and 85% respectively in CA, which were significantly higher than those in healthy control cases (only 35% and 30%, respectively, X2=11.87,P<0.01; X2 =18. 15,P<0. 01) . The SHP-1 and/or SHP-2 positive cells in CA skin lesions were mainly distributed in prickle layer, showing as brown yellow, with the positive staining located in cytoplasm. Contrastively, the SHP-1 and/or SHP-2 positive cells in healthy controls were rare and mainly distributed in basal layer, showing as pale yellow with the positive staining located in cytoplasm. There was no significant correlation between the expression of SHP-1 and SHP-2 in CA( rs = 1.0, P>0.05 ). Conclusion The expressions of SHP-1 and SHP-2 increase in HPV6/11 positive CA, which suggest that with the infection of HPV6/11, SHP-1 and SHP-2 may play a regulatory role in the proliferation of keratinocytes.

Transformation and quality improvement of clinical pharmacy is key to assuring quality of care for public hospital reform.The clinical pharmacist working model has been established after years of exploration in China,which plays a positive role in promoting such quality and optimizing the allocation of medical resources.However,with the advance of the health care reform,the original working model and methods of clinical pharmacists need to be further improved to meet emerging demands.This paper puts forward a new model of clinical pharmacist development based on the concept of hospital total quality management,which involves the clinical pharmacists′ duty,the work model from the “Pay a visit to bedside”to “Stay by bedside”in clinic,professional development training and performance evaluation.The reform provides a feasible way for the transformation and development of clinical pharmacists in public hospitals.

Objective To investigate the effects of ursolic acid and rhynchophylline in Uncariae Ramulus Cum Uncis on human hepatoma HepG2 cells; To discuss its antihepatoma mechanism. Methods Culture the human hepatoma HepG2 cells with 50, 25, 12.5, 6.25 μmol/L ursolic acid, rhynchophylline for 24, 48, 72 hours respectively. 1%DMSO was set as negative control group. CCK-8 based cytotoxicity assay was used to detect the growth of HepG2. Acridine orange fluorescent staining was used to observe human hepatoma HepG2 cells cultured with 50 μmol/L ursolic acid, rhynchophylline and 1%DMSO for 48 hours were observed. Results Ursolic acid significantly acted as a disincentive to the growth of HepG2 cells, which was in positive correlation with time and concentration. Inhibited effect by rhynchophylline on HepG2 cell proliferation was weaker than ursolic acid. Pathological observation showed that most of the cells in rhynchophylline group showed cell shrinkage, dense pulp coating and nuclear staining edge set, and most of the cells in the ursolic acid group showed apoptosis late changes, such as nuclear cleavage and apoptotic bodies. Conclusion Ursolic acid and rhynchophyllinein Uncariae Ramulus Cum Uncis can inhibit the proliferation of HepG2 cells and can induce apoptosis.

Objective To explore the expression of tyrosine phosphatase containing c-Src homology SH2 (SHP-2) in condyloma acuminatum. Methods Phosphorylated tyrosine and SHP-2 were detected in skin lesions of 30 patients with condyloma acuminatum, tumor tissues of 13 cases of cervical cancer and normal foreskin tissues of 11 normal controls by SP immunohistochemical stain. Results In the foreskin tissue, the phosphorylated tyrosine and SHP-2 were mainly expressed on the nuclei of kerotinocytes adjacent to the basal layer, and the number of cells with positive expression was not so many. In condyloma acuminatum, the positive cells arranged in patches, phosphorylated tyrosine and SHP-2 distributed in the cytoplasm. In cervical cancer, the expression of phosphorylated tyrosine and SHP-2 were mainly in the cytoplasm, diffusely distributed, and not in the nuclei. The positive expression rates of phosphorylated tyrosine and SHP-2 in condyloma acuminatum and cervical cancer were 96.67% (29/30) and 100% (13/13), respectively. However the cytoplasm of normal foreskin showed negative expression(0/11). Conclusions There is an aberrant activation of phosphorylated tyrosine and SHP-2 in condyloma acuminatum and cervical cancer. SHP-2 may play an important role in the carcinogenesis.
