Objective To explore the role of apoptosis and the expression of X-linked inhibitor of apoptosis protein(XIAP) in polymorphonuclear neutrophils(PMNs) during acute pancreatitis(AP).Methods Blood from normal control(NC,n=15),mild acute pancreatitis(MAP,n=15) and severe acute pancreatitis(SAP,n=15) were collected.PMNs apoptosis was detected by flow cytometry.PMNs were isolated from each group and XIAPmRNA and protein levels were assessed by RT-PCR and Western Blotting.Results PMNs apoptosis in SAP group was(2.15?0.40)%,MAP group was(4.16?0.14)%,NC group was(4.31?0.12)%.PMNs apoptosis rate in SAP and MAP groups was decreased compared to NC group(P

Objective To detect serum IgG4 and IgE levels in children with allergic asthma and rhinallergosis to provide an im-portant laboratory evidence for its diagnosis ,treatment and prevention.Methods The serum IgG4 and IgE levels were detected in 118 children patients with allergic asthma ,167 children patients with rhinallergosis and 150 healthy children(control group) under-going physical examination in the same period.Results The levels of serum IgG4 and IgE in the allergic asthma group and rhinal-lergosis group were significantly higher than those in the control group ,the difference was statistically significant (P<0.05).In the intra-group comparison of the allergic asthma group and rhinallergosis group ,the positive rate of serum IgG4 was higher than that of serum IgE ,the difference was statistically significant (P<0.05).The positive rate of joint detection of serum IgG4 and IgE in these two groups was higher than that of single index detection ,the difference was statistically significant (P<0.05).The positive rate of serum IgG4 in the allergic asthma group was lower than that in the rhinallergosis group ,the difference was statistically sig-nificant(P<0.05).The positive rate of serum IgE in the allergic asthma group was lower than that in the rhinallergosis group ,but the difference was not statistically significant (P>0.05).Conclusion Serum IgG4 and IgE have a certain clinical significance in the occurrence ,treatment and surveillance of allergic asthma and rhinallergosis in children.

In view of the lack of teaching methods in the cultivation of medical professionalism, this paper puts forward some important strategies for improving medical students' professionalism through discussion-based film and television appreciation. High-quality discussion-based film and television appreciation can be designed according to the four links of film selection, concentrated viewing, independent discussion and summary feedback. At the same time, in practice, attention should be paid to three key issues: selecting appropriate films, ensuring the quality and depth of discussion, and paying attention to feedback and evaluation. Practice has proved that discussion-based film and television appreciation makes the cultivation of professionalism more attractive, and can promote the professional knowledge and professional spirit, enhance students' professional enthusiasm, promote the understanding of the connotation of professionalism and reflection on related issues. Medical colleges should continue to improve the design of film viewing in practice, so as to help students better absorb humanistic nutrients from the discussion and enhance the teaching effect of professionalism.
