Objective:To inspect and improve physician professionalism effectively and preliminarily build eval-uation index system for physician professionalism. Methods:A sample of 240 physicians selected randomly from 8 Three-A hospitals in Shanghai were investigated using a self-designed questionnaire. Then the method of analyt-ic hierarchy process was performed in this study to construct the evaluation model of physician professionalism and determine every index weight. Results: An index system was initially built for physician professionalism evalua-tion. This system comprised three level-1 indexes namely moral quality characteristics, achievement action char-acteristics and vocational cognitive characteristics, as well as 14 level-2 indexes that drew from level-1 including responsibility etc. , at the same time determined their weight distribution. The judgment matrix had completely con-sistency through consistency check, indicating that the weight coefficient can reflect the relative importance of every index. Conclusion:Moral quality characteristics is one of the most important components of physician professional-ism evaluation; responsibility consciousness and vocational ideal are vital for the growth of physicians; lifelong learning and communication skills with high weight reflects needs of modern health care industry development;medical ethics consciousness has a trend of strengthening in physician groups, and enhancing evaluation index sys-tem for physician professionalism has the operability.

Graduate medical education, postgraduate medical education and continuing medi-cal education between China and the United States were compared in order to explore a better physi-cian training system of China. The physician training system of the United States has a series of ad-vantages such as strict access system, uniform training standard and closely linked among each stage, etc. We should make clear medical education standards and strengthen the cohesion between each stage, standardize the management mode and perfect the management system and promote regular as-sessment system.

BACKGROUND: The vibration of high speed handpiece during tooth preparation may have adverse effect on the continuous force of the bonding interfaces among the cement, dentin, and post core. OBJECTIVE: To find the effect of different types of cements on the coronal microleakage of fiber post under different tooth preparation timings, and to provide evidence for the clinical operation. METHODS: The extracted mandibular premolars were divided into 3 groups, and they were cemented by Rely X luting, Panavia F and Paracora 5 mL, respectively. Each group was averagely divided into 3 subgroups: A, B, C groups which were prepared 15 minutes, 45 minutes, and 90 minutes after the cements mixed. All roots were then dyed and transparented. The teeth were observed under stereoscopic microscope and the dyeing scores were also recorded. RESULTS AND CONCLUSION: Rely X luting caused the highest coronal microleakage of fiber post, followed by Panavia F, while Paracore 5 mL, brought about the lowest under the same tooth preparation timing. Different tooth preparation timing caused no significant effect on the coronal microleakage of fiber post when the cement had been completely set.

Objective To investigate the expression of apoptosis-related neuclosome assembly protein-1(NAP-1) gene in related brain region of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine(MPTP) treated mice and beta-amyloid treated rats. Methods The animal models with central nervous system degeneration were established by consecutive administration of MPTP to C57BL mice and injection of beta-amyloid to brain ventricular of SD rats. The RNA in striatum and substantia nigra of mice and the RNA in cortex and hippocampus of rats were extracted. The levels of NAP-1 mRNA in these samples were estimated by RT-PCR. Results For mice, the expression of NAP-1 were decreased after MPTP treatment in substantia nigra, while its expression showed no significant change in striatum. In contrast, no effect on NAP-1 gene expression by beta-amyloid injection can be detected in cortex and hippocampus of rats. Conclusions The apoptosis of dopaminergic neurons in nigrostriatal pathway after MPTP treatment may be related to the expression of NAP-1 gene. But the mechanism of neurodegeneration after beta-amyloid injection in rats may be different.

Objective: To study the influence of allopurinol and febuxostat on IL-1β and NALP3 levels and liver and kidney function in gout patients with hyperuricemia. Methods: A total of 108 patients with stable gout accompanied by hyperuricemia were selected and randomly divided into control group and observation group according to the digital table, with 54 cases in each group.The control group was given allopurinol 100mg/time, orally, 3 times/d.The observation group was given febuxostat 40mg/time, orally, 1 time/d.The two groups were treated 4 weeks for 1 course, continuous treatment for 6 courses.The contents of serum IL-1β and NALP3, and renal function[creatinine(Scr), urea nitrogen(BUN), glomerular filtration rate(GFR) and uric acid(UA)], liver function[alanine aminotransferase(ALT) and aspartate aminotransferase(AST)]of the two groups were detected, and the adverse reaction of the two groups were observed. Results: After treatment, the contents of serum IL-1β and NALP3 of the observation group decreased gradually, which were lower than those of the control group(t=1.910, 2.196, 4.954, 1.732, 5.944, 7.935, all P<0.05). After treatment, the blood UA of the two groups decreased significantly, the blood UA of the observation group was lower than the control group(t=9.772, P<0.05). The other kidney function indicators had no statistically significant differences between the two groups (t=0.082, 0.923, 1.395, all P>0.05). The liver function indicators of the two groups had no statistically significant differences(t=0.860, 0.563, all P>0.05). The incidence rate of adverse reactions in the observation group was 5.77%, which was lower than 20.75% in the control group(χ²=5.101, P=0.024). Conclusion Febuxostat in the treatment of gout with hyperuricemia can effectively reduce the level of serum UA, and inhibit the expression of inflammatory factors such as IL-1β and NALP3, with high safety, which is worthy of clinical promotion.
