Objectives Comparative analysis on epidemiological characteristics of measles in Minhang District before and after Large scale supplementary immunization activities of measles containing vaccine(MCV) in 2010. Methods Measles incidence data of MCV-SIA in 2010 and the first five years before 2010 (from January 1, 2005 to December 31, 2009), the next five years (from January 1, 2011 to December 31, 2015) and the second five years (from January 1, 2016 to December 31, 2020) after were collected. Descriptive epidemiological method was used for comparative analysis. Results The incidence rate of measles in Minhang District, Shanghai after MCV-SIA in 2010 showed a significant downward trend, The average annual incidence (per 100 0000) in the first 5 years before 2010 was 155.96, SIA was 30.08,The next five years was 29.52, The second five years was 2.84,There was statistical difference in the annual incidence rate between the four groups.（χ²=3165.821，P<0.01）. The annual incidence rate between registered residence and non registered residence population were not statistically different after second SIA years after the SIA（χ²=1.646，P=0.223）The proportion of 8-month-old children under the age of MCV decreased from 15.46% in the first five years of MCV-sia to 5.88%,In the second five years after MCV-sia, the proportion of 10-14 age group increased from 7.81% to 13.83%, The susceptible population of measles before MCV-SIA was less than 8 month old and under the age of MCV initial immunization, no migrant workers with no history of immunization and adults with registered residence. Once there is a source of infection, it is easy to cause the spread of the epidemic. After MCV-SIA, foreign students in international schools and nonworking population became the focus of measles. Of the 95 cases in which measles virus genotypes were available in the next five years, 2 (2.11%) were A genotype, and 93 (97.89%)were the indigenous H1 genotype ; Of the 7 cases in which measles virus genotypes were available in the second five years,7 (100%)were the indigenous H1 genotype . Conclusions After MCV-SIA, the comprehensive measles prevention and control measures can effectively control the incidence and prevalence of measles in Minhang District. But circulation of the indigenous H1 genotype was not interrupted, the work of normalization measures to eliminate measles also needs to cooperate with many departments to strengthen the prevention and control measures of measles in foreign schools and the nonworking population.

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common disease in men. In recent years, it has become younger, which seriously affects the patients＇quality of life. A deep understanding of the pathogenesis of CP/CPPS will help the choice of treatment. Its pathogenesis is not only related to immune factors, but also related to local microcirculation disorders of the prostate, endocrine hormone imbalance, adjacent gut microbes and compression of lumbar intervertebral disc, but it has not been fully elucidated. Therefore, this article aims to review the pathogenesis of CP/CPPS and provide directions for its diagnosis and treatment.

Objective To discuss the nursing effect and application value of refinement process of nursing management mode in hospital infection control in the operating room.Methods 620 patients who will carry out surgi-cal treatment were selected as the research subjects.310 cases without detailed process of nursing management were included in the control group,and 310 patients with refinement process of nursing management were selected as obser-vation group.The clinical nursing effects of two groups were recorded.Results Observation group surface 88.94%, medical staff hand 92.54%,disinfectant 95.65%,100.00% sterile items.The control surface 81.38%,80.00% of medical personnel hand,disinfectant 75.93%,90.00% sterile items,the monitoring qualified rate between two groups had statistically significant differences (χ2 =5.021,4.596,7.581,6.725,all P <0.05).The sores of nursing safety, operating room management,form filling,ward nursing in the observation group were (95.37 ±4.66 )points, (94.27 ±5.21 )points,(96.13 ±3.29)points,(95.03 ±4.87)points.Those in control group were (90.12 ± 2.03)points,(89.13 ±2.26)points,(90.03 ±1.88)points,(88.17 ±2.25)points,the differences between two groups were statistically significant (t =18.185,15.935,28.343,22.514,all P <0.05).The scores of nurses and patients communication,nursing procedures,ward environment,care attitude in the observation group were (24.19 ± 0.87)points,(24.03 ±0.64)points,(24.51 ±0.45)points,(24.28 ±0.36)points.Those in the control group were (21.54 ±1.65 )points,(20.88 ±1.72)points,(20.95 ±1.66)points,(21.09 ±0.89)points,the differences between two groups were statistically significant (t =25.013,30.220,36.443,58.502,all P <0.05).Conclusion Refinement process of nursing management mode application helps to control nosocomial infection in operating room of hospital infection control,improve the quality of clinical nursing services,improve the clinical nursing satisfaction, which is worthy of popularization and application in clinic.

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.

Objective To measure the titers of varicella live attenuated vaccines ( VarV) during the process of transportation and storage in different seasons and communities of Minhang Distract, Shang-hai, to evaluate the operation of cold chain system and the thermal stability of vaccines and to provide refer-ences for the management, introduction, research and development of vaccine in future.Methods Four communities with high outbreak rates of varicella during 2012 to 2013 and four communities with low out-break rates were randomly selected from 13 communities in Minhang District, Shanghai.The titers of VarVs were detected by using the quantitative plaque assay before and after 30 days of storage in November 2013 and February, May, August 2014.Results The overall rate of qualified VarVs was 90.63% with a geo-metric mean titer (GMT) of 3.67 (LgPFU/0.5 ml).96.88%of the VarVs produced by company C met the quality standard with a GMT of 3.89 ( LgPFU/0.5 ml) followed by those produced by company B with a rate of 91.67%and a GMT of 3.75 ( LgPFU/0.5 ml) .The rate of qualified VarVs produced by company A was the lowest, which was 80.00%, with GMT of 3.29 (LgPFU/0.5 ml).There were significant differences in the rates of qualified VarV among the three companies (χ2=8.288, P=0.016).The rate of qualified vac-cines in communities close to the Shanghai Minhang Center for Disease Control and Prevention ( Minhang CDC) was 91.67%, while 100%of the vaccine samples collected form the communities at a middling dis-tance from or far from the Minhang CDC met the quality standard.No significant difference in the rate of qualified vaccine was found among the three types of communities (χ2=3.441, P=0.179).The quarterly rates of qualified vaccines produced by B and C companies were 100%except for the third quarter.The rates of qualified vaccines produced by A, B and C companies in the third quarter were respectively 70.00%, 66.67%and 87.50%.No statistical differences in the quarterly rates of qualified vaccines were found among the three companies (χ2=1.25, P=0.7412;χ2=6.545, P=0.088; χ2=6.194, P=0.103).No statistical differences in the rates of qualified vaccines before and after 30 days of storage were found among the three companies (χ2=0.625, P=0.347;χ2=0.000, P=1.000;χ2=2.065, P=0.492).Conclusion A well-managed and-operated cold chain system was implemented in Minhang District in the storage and transport of vaccines as well as other related links.The thermal stability of vaccines produced by company C was better than those of the other two companies.A surveillance for the titers of vaccines produced by com-pany A should be strengthened.

OBJECTIVESTo survey on the vaccination of varicella live attenuated vaccine among 4-17 children in Minhang District, and analyze the protective effect against varicella.

METHODSWe collected outbreak chickenpox cases reported from infectious disease report system and surveillance units in Minhang district from 1st May in 2012 to 30th Apr in 2013. The 1: 3 matched case-control study was conducted to questionnaire the legal guardian of the cases and control group, and calculate the protective effect and effective term of protection. The survey included vaccination, chickenpox exposure history, previous history of varicella illness, suffering from the symptoms of chickenpox, the vaccinations brand, etc. The criteria of accepted case were those healthy students who were in the same class with those chickenpox cases. The accepted matched controlling data were those children who were from the same class with outbreak chickenpox cases without varicelliform eruption, similar live condition, the closest house, the same gender, the closest age. This study investigated 390 cases of patients and the control group included 1 170 cases. Chi-square test was used to compare the vaccination of cases and controls, as well as the incidence of chickenpox vaccination different brands VarV, Mantel-Haenzel chi-square test was applied to compare the protective effect of the two groups.

RESULTSVarV overall vaccination rate was 68.3% (1 065/1 560), among them, the case group coverage was 45.1% (176/390), significantly lower than the control group (76.0% (889/1 170)) (χ² = 128.55, P < 0.01). The coverage in children of 4-10 years old group was 88.4% (375/424), significantly higher than the 11-17 years old group (60.7% (690/1 136)) (χ² = 109.40, P < 0.01). The overall protective effect of VarV was 78.10% (71.82%-82.98%).Vaccinated group incidence ratio was 16.5% (176/1 065), significantly lower than the unvaccinated group (43.2% (214/495)) (χ² = 128.55, P < 0.01). The chickenpox risk of the children who were vaccinated was lower than those who were not, and the OR (95%CI) was 0.22(0.17-0.28) . Proportion of the fever and the typical symptoms of varicella zoster were 26.1% (46/176), 8.0% (14/176) in the children vaccinated VarV, significantly lower than children without VarV vaccination history (54.7% (117/214) , 18.2% (39/214) ) (χ² values were 32.33 and 8.67, respectively. P values both <0.01). The varicella incidence was 17.4% (139/797) in children vaccinated domestic VarV, and it was 13.8% (37/268) in the group of imported VarV (χ² = 1.92, P = 0.184) . The average duration of effective protection period for domestic and imported VarV was (6.2 ± 2.7), (6.3 ± 3.4) years (F = 2.24, P = 0.136).

CONCLUSIONSThe risk of varicella incidence and the proportion of fever or typical varicella zoster were lower in the one dose of VarV vaccinated; Effective protective effect was consistent in the children with domestic or imported VarV vaccination.
