Objective To explore the expressions and the roll of p63mRNA and murine double minute 2(MDM-2) protein in esophageal squamous cell cancer and the prognosis of the cancer.Methods The expressions of p63mRNA and MDM-2 protein in 38 cases of esophageal squamous cell carcinoma tissues and the corresponding esophageal normal tissues were detected using reverse transcriptase polymerase chain reaction(RT-PCR) and immunohistochemistry. Results The positive rates of deltaNp63 mRNA in all malignant and normal tissues were 63.5% and 52.63% respectively,without significant difference.The expression of the DeltaNp63 mRNA was significantly higher in low differentiated group than in well and moderate differentiated group,without significant difference in age,gender,lymph node metastasis and clinical stage.Only 1 of 38 cases of esophageal squamous cell carcinoma tissues presented TAp63 mRNA expression and all esophageal normal tissues had no TAp63 mRNA expression.The positive rates of MDM-2 protein in esophageal squamous cell carcinoma tissues and normal tissues were 65.79% and 5% respectively,with significant difference.The expression level of the MDM-2 protein was higher significantly in low differentiated group than in well and moderate differentiated group,with significant difference in clinical stage and without significant difference in age,gender and lymph node metastasis.The DeltaNp63 mRNA expression in the esophageal squamous cell carcinoma tissues was positively related to MDM-2 protein expression.Conclusion The major isotype expressed in the esophageal cancer and epithelia is DeltaNp63,which may play an important role in the carcinogenesis,development and prognosis of the esophageal squamous cell carcinoma.TAp63 is not the major isotype expressed in the esophageal cancer and epithelia,and not related to the carcinogenesis of esophageal squamous cell carcinoma.High expression of MDM-2 protein is associated with the carcinogenesis of esophageal squamous cell cancer and related to the prognosis of esophageal squamous cell carcinoma.DeltaNp63 regulates the cell cycle and apoptosis through the pathway of MDM2 and causes the carcinogenesis of esophageal squamous cell cancer.

Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) has become a widely used method in the field of microbial identification. Its obvious advantages including rapidity, great accuracy and high throughput attract many researchers to investigate its potential for usage in other microbiological fields. Currently, several studies have reported MALDI-TOF MS-based analysis of bacterial resistance to antibiotics, which can identify the specific heterogeneous spectrum peaks related to drug resistance through simple visual analysis of the spectrum or more complex analysis of the entire spectrum using informatics methods and statistical approaches. Therefore, MALDI-TOF MS has become a potential tool for detecting antibiotic resistance in bacteria. This review mainly summarized the progress in MALDI-TOF MS-based analysis of bacterial resistance to antibiotics.

Objective To explore the impact of the systematic social skills training on recovery of chronic schizophrenia patients with negative symptom and social skills defects.Methods A total of 82 cases of long -term hospitalized patients with chronic schizophrenia were randomly divided into intervention group and control group by digital table,41 cases in each group.The two groups received psychiatric routine therapy and nursing,and general entertainment therapy,and systemic social skills training was conducted in the intervention group for 12 weeks.PANSS and SSC were respectively used to evaluate the two groups before and after the intervention.Results After 12 weeks of systematic social skills training,the total score of SSC[(24.5 ±4.5)points]in the intervention group was apparently lower than that in the control group[(29.2 ±5.2)points],and the difference was statistically significant(t =3.212, P <0.01).Compared with the control group[(20.5 ±4.3)points,(27.2 ±4.2)points,(59.1 ±9.5)points],in the intervention group the score of negative symptom mental pathology and total score of PANSS were (14.9 ± 3.7)points,(24.5 ±3.5)points,(52.8 ±7.1)points.The differences of total score between the two groups were sta-tistically significant(t =5.199,3.317,3.239,all P <0.01),while the positive symptoms score was not statistically significant(P >0.05).Compared with before intervention,in the negative symptom table,the differences of total score N2,N3,N4,N6 had statistically significant differences(t =4.533,5.413,4.501,4.668,all P <0.01).Conclusion The systematic social skills training can greatly promote chronic schizophrenia patients with negative symptom and social skills defects,improve their social skills and life qualities.

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.
