Objective: To investigate the influence of intermittent cold stress on collagen content of atherosclerotic plaque in experimental ApoE-/-mice.
Methods: A total of 20 male ApoE-/-mice at 8 weeks of age were divided into 2 groups:Experimental group, the mice had intermittent cold exposure at (4 ± 1)°C from 8am to 12noon and Control group, the mice were living at (24 ± 2) °C. All animals were treated for 12 weeks, n=10 in each group. The collagen content of atherosclerotic plaque at the aortic root in ApoE-/-mice was observed by Masson staining, the protein expressions of aortic MMP-2, MMP-9 and TIMP-1 were examined by Western blot analysis.
Results: Compared with Control group, the Experimental group presented the lower collagen content of atherosclerotic plaque at the aortic root, higher protein expressions of MMP-2, MMP-9 and lower protein expression of TIMI 1.
Conclusion: Intermittent cold stress may disturb the balance of MMP/TIMP and decrease collagen content of atherosclerotic plaque to form vulnerable plaque in experimental ApoE-/-mice which may cause acute coronary syndrome.

Objective To study the clinical characteristics and treatment of primary nasal B-cell lymphoma (PNBCL). Methods A retrospective analysis was performed based on the clinical records of 18 PNBCL cases who were treated from January 2009 to June 2015. The clinical manifestations, imaging features, diagnosis approaches and treatment of them were analyzed. Results The main symptoms were nasal obstruction and rhinorrhea. Of all patients, 15 cases were in Ann Arbor stageⅠE-ⅡE, and 3 cases were in Ann Arbor stageⅢE-Ⅳ. The median age was 51 years (12-76 years). The ratio of men to women was 11:7. Only 1 patient had B symptoms. Elevated LDH levels were observed in 4 patients. 13 patients were diffuse large B-cell lymphoma(DLBCL), 3 patients were mantle cell lymphoma, and 2 patients were Burkitt lymphoma. CT examination showed the abnormal nasal soft tissue shadow, with unilateral location and light to moderate enhancement. 14 patients received combination chemotherapy only, and 3 patients received chemotherapy and radiotherapy. Total effective rate was 82.3 % (14/17). At the time of last follow-up, 5 patients died, and the 3-year OS rate was 54.5%(6/11). Conclusions Most PNBCL patients are in Ann Arbor stageⅠE-ⅡE and B symptoms are rare, and the most common pathological types is DLBCL. The treatment for PNBCL is chemotherapy, radiotherapy can assist, but the prognosis is poor, and innovative chemotherapy regimens are necessary.

Objective To analyze the genetic characteristics of breakthrough varicella-zoster virus infection during the varicella outbreaks in Minhang District of Shanghai in 2013-2014. Methods Samples of the varicella-zoster liquid were collected from patients with chickenpox in Minhang District in 2013-2014 and used for the extraction of genomic DNA. The open reading frame ( ORF) of 22 and 62 regions were se-quenced and further analyzed by using bioinformatics methods. Results A total of 24 samples were success-fully collected and sequenced, and all of them were wild strains. Among the 24 varicella-zoster virus strains, 23 strains were highly homologous to the parental strain ( P-Oka) and the vaccine strain ( V-Oka) , indica-ting that they belonged to J genotype. Only one strain, whose genotype was between M and E, was highly ho-mologous to the mosaic( M) CA123 strain ( M1 genotype) , indicating that it might belong to M1 genotype. Conclusion The epidemic strains of varicella-zoster virus in Minhang District were mainly J genotype. Lo-cal epidemic of M and other genotypes of varicella-zoster virus also existed. There were some gene variations in different strains of J genotype. These varicella-zoster virus strains of non-vaccine genotypes might be one of the reasons causing the breakthrough cases of chicken pox.

Objective To evaluate the epidemiological efficacy of 23-valent pneumococcal poly-saccharide vaccine on the clinical symptoms and the incidence of respiratory tract infections in the elderly over 60 years old in Minhang District, Shanghai. Methods A prospective cohort study was conduct, in which the sample size was 1 200 for both inoculated and uninoculated groups. This study followed the two groups of subjects every quarter for a year. Clinical symptoms and the incidence of respiratory tract infectious diseases as well as the acute onset of chronic respiratory diseases were compared between the subjects of the two groups. Results Compared with the uninoculated group, less people in the inoculated group developed the clinical symptoms of respiratory tract infection (RR=0. 894, 95% CI: 0. 804-0. 994). Immunization with the 23-valent pneumococcal polysaccharide vaccine protected 57. 7% of the senior citizens (≥75 years old) from respiratory tract infections(95% CI:0. 207-0. 775). Conclusion The 23-valent pneumococcal polysaccharide vaccine can effectively reduce the incidence of respiratory tract infections in the elderly aged 60 years old and over and protects the elderly aged 75 years old and over from respiratory tract infections. Further studies on the immunological efficacy of 23-valent pneumococcal polysaccharide vaccine should be carried out by measuring the antibody titers before and after vaccination.
