Objective To study the effects of protein kinase C (PKC) inhibitor staurosporine (STS) on the proliferation and apoptosis of human cholangiocarcinoma QBC-939 cells and to explore its possible mechanism. Methods CCK-8 was used to detect the effects of PKC inhibitor STS on the proliferation of human cholangiocarcinoma QBC-939 cells. The effects of STS on the ultrastructural characteristics of QBC-939 cells were observed by routine transmission electron microscopy (TEM). The apoptosis rate and the cell cycle distribution of QBC-939 cells were detected by flow cytometry. The expression of cyclin B1,Cdk1 and p-Cdk1 in QBC-939 cells was detected by Western blotting. Results STS could significantly inhibit the proliferation of QBC-939 cells in a dose-dependent manner (P <0. 05) and the half inhibitory concentration ( IC50 ) of QBC-939 cells at 24th and 48th h was 334 nmol·L-1 and 118 nmol · L-1 , respectively. TEM observed that STS could induce typical apoptotic bodies and super-microstructural changes of QBC-939 cells. By Annexin V-FITC/ PI double labeling flow cytometry,we found that the apoptotic rate of QBC-939 cells after treatment with STS for 0,12,24 and 48 h was (10. 16±4. 52)% ,(22. 35±2. 19)% ,(34. 27±2. 30)% and (59. 70±5. 97)% ,respectively. By flow cytometry,compared with the control group,STS could significantly increase apoptosis rate of QBC-939 cells,decrease the percentage of cells in G0 / G1 phase and increase the percentage of cells in G2 / M phase (P<0. 05). Western blotting proved that the expression levels of cyclin B1 and Cdk1 proteins in the STS-treated QBC-939 cells were significantly decreased (P<0. 05),while the expression level of p-Cdk1 protein in the STS-treated QBC-939 cells was significantly increased ( P < 0. 05 ). Conclusion STS can significantly inhibit cell proliferation and induce apoptosis of human cholangiocarcinoma QBC-939 cells and the mechanism may be related to cell cycle arrest at G2 / M phase.

Therefore, game-teaching methods were employed to enrich teaching methods,to make medical teaching more vivid and to promote medical students' learning interests. In this paper,application of game-learning idea in the medical teaching process was discussed from multiple aspects including the story of the game,incentives of the game and the punitive measures of the game.

The integration of natural and human sciences has resulted in the evolution of the connotation and framework of medicine, thus enriching its scientific nature. The high degree of the integration of the scientific, technological, economic, and social factors in the field of the medical sciences with human sciences reveals the significance of the human spirit in medical care. Reliability, impartiality, effectiveness and satisfaction, which embody the human spirit in medical care, signify a hospital's character and core values and are the prerequisite and guarantee for satisfying medical care. The authors point out emphatically that the development of the codes of ethics and the human ideology in medical care constitutes both the core of the cultural construction of the modern hospital and an important foundation for its economic growth.

Cone-beam computed tomography(CBCT) was used to analyze the anatomic morphology of maxillary canine fossa of different sagittal skeletal patterns patients;implants of various dimensions were virtually placed into the maxillary premolars region.The relationships among maxillary canine fossa and implant were analyzed.The depth of the maxillary canine fossa was(4.33±0.73),(3.77±0.58),(5.18±0.93)mm in the 1st premolar region of class Ⅰ,Ⅱ and Ⅲ respectively.The depth of the maxillary canine fossa was(3.20±0.63),(2.81±0.58),(3.90±0.79)mm in the 2nd premolar region of class Ⅰ,Ⅱ and Ⅲ respectively.There were no significant statistical differences in genders,sides,and loss of tooth.And there were significant statistical differences in three classes(P<0.05).The length of the implants was (10.30±1.70)mm(d=3.3 mm) and (8.77±1.58)mm(d=4.1 mm) in the 1st premolar region and (8.09±1.51)mm(d=3.3 mm),(6.69±1.35)mm(d=4.1 mm) in the 2nd premolar region in patients with teeth and buccal perforation;the length of the implants was (8.98±1.54)mm(d=3.3 mm) and (7.67±1.52)mm(d=4.1 mm) in the 1st premolar region and(7.09±1.59)mm(d=3.3 mm) and (5.79±1.34)mm(d=4.1 mm) in the 2nd premolar region in patients with tooth loss,respectively.There were significant statistical differences in loss of tooth(P<0.05).Analyzing of spatial relationships among maxillary canine fossa and implants of different sagittal skeletal patterns patients especially class Ⅲ patients,by using CBCT has important significance in guiding dental implants.

Morphine antagonist naloxone (3mg/kgiv ) induced a rise in blood pressure,pulse pressure & respiratory rate in the rat under hemorrhagic shock. It also improved the survival rate. ?Receptor antagonist pheno-xybenzamine ( 1 mg/kg iv ) or adrenalectomy abolished the beneficial effects of naloxone. Reserpine ( 1 mg/kg ip for 5 d) which depleted catecholamines of periphal sympathetic nervous system could not abolish naloxone effects. Resrpine plus adrenalectomy abolished naloxone actions again. It is suggested that the effect of naloxone on the blood pressure is mainly due to release of catecholamine from adrenalmedu-llary. The results of isolated adrenal perfusion indicated that naloxone could not induce a rise in catecholamine concentration of perfused liquid. It is suggested that the action of naloxone on catecholamine release may not be a result of direct action upontbe chromaffin cells.

EBP50(ERM-binding phosphoprotein-50),a multifunctional adapter protein with 358 amino acids and two PDZ domains, regulates cell growth and migration. Lines of evidences indicate that it is a potential cancer suppressor protein. Loss of heterozygosity (LOH) and intragenic mutation of the ebp50 gene have been found in both primary breast tumors and breast cancer cell lines. EBP50 suppresses the breast cancer cell proliferation via its interaction with many tumor suppressor protein including PTEN, SYK, MERLIN, etc. Here the molecular structure of EBP50, signal pathway regulated by EBP50, and the relationship between breast cancer development and EBP50 are discussed.
