Methods Interview,question-naires and Principal component analysis were used to explore the coping strategies of college students on infectious diseases. Results Col-lege students' coping strategies to infectious diseases involving seeking social support and active problem solving two principal components, in-volving 19 aspects. Conclusion As for colleges,a support platform should be built and the ability to actively solve problems urged to be strengthened for students. Among the coping strategies of College students’ toward to the infectious diseases,students choose to seek social support more than to solve the problem initiatively,indicating that gender differences and the environment may be related. The results provide a theoretical reference to public health and health education.

The 53rd ASH meeting was held in San Diego in December 2011. The meeting has received many advanced reports on the diagnosis and treatment of multiple myeloma (MM).On therapy,with the application of thalidomide, lenalidomide and bortezomib as inductive treatments, the clinical outcomeshave been improved greatly in MM patients.Pomalidomide,a new immunomodulator,can be hopefully used as a frontline medicine for MM because of its high response. Bendamustine combination with other treatments induced efficient response and good response rates in MM patients with renal insufficiency or relapsed/refactory disease. Currently autologous stem cell transplantation is still the standard care for newly diagnosed young MM patients.At this time other kinds of novel agents have entered into clinical trials and have shown a bright future of application.

Objective To explore the effect of swallowing training on dysphagia in patients with head and neck neoplasm receiving ra-diotherapy. Methods 60 patients with head and neck neoplasm receiving radiotherapy from March, 2014 to August, 2015 were divided into intervention group (n=30) and control group (n=30) randomly. The control group received routine nursing and relevant health education, while the intervention group received swallowing training from 2 weeks before to 3 months after radiotherapy. They were assessed with Functional Oral Intake Scale and M. D. Anderson Dysphagia Inventory 1 week, 3 months after radiotherapy. Results The scores of Function-al Oral Intake Scale (Z=-3.195, P<0.01), the total score of M. D. Anderson Dysphagia Inventory and the subscores (t>4.385, P<0.01) were better in the intervention group than in the control group 1 week after radiotherapy, as well as 3 months after radiotherapy (Z=-4.436, P<0.01;t>5.361, P<0.01). Conclusion Swallowing training could improve the condition of dysphagia of head and neck neoplasm patients after radiotherapy.

Objective　To investigate the relationship between soluble tumor necrosis factor receptors (sTNF-R), TNF-α, TNF-α/sTNF-R and rheumatoid arthritis. Methods　 Serum levels of sTNF-RⅠ, sTNF-RⅡ and TNF-αwere measured in 28 patients with active RA and 12 patients with inactive RA and 30 healthy controls, using double antibodies sandwiched ELISA. Results　The results showed that serum levels of sTNF-RⅠ, sTNF-R Ⅱ and TNF-α　were significantly higher in the group of patients with active RA than those　found　in healthy group and　in the patients with inactive RA. Serum levels of both sTNF-RⅠ, sTNF-RⅡ and TNF-α　were also significantly higher in patients with inactive RA than in healthy group(P＜0.01 for all). In RA, the serum concentrations of sTNF-RⅠ and sTNF-RⅡ were positively correlated with the levels of ESR，CRP，Ritchie index. Conclusions　These results suggest that the serum levels of sTNF-RⅠ and sTNF-RⅡwere significantly increased and positively correlated with the disease activity. The determination of serum levels of sTNF-RⅠ and sTNF-RⅡ can be regarded as a useful laboratory parameter for diagnosis of RA,monitoring of the disease activity and assessment of prognosis.

Objective To investigate the effects of dieting and exercise intervention on lipid level in patients with hyperlipidemia.Methods Health education including dieting and exercise interventions was given to 1,800 patients with hyperlipidemia.Serum total cholesterol(TC), triglyceride(TG), high density lipoprotein(HDL-C)and low density lipoprotein (LDL-C)levels were assessed before and after interventions.Result TC, TG and LDL-C levels were decreased and HDL-C increased after interventions with statistical significance(P<0.01).Conclusions Dieting and exercise intervention can be effective in controlling lipid levels effectively.Health education should vary among individuals to achieve good effects.
