Self-control brings important effects on the process and maintenance of health behavior change in individuals, but its mechanism is unclear.Healthy behavior change could be divided into goal-oriented behavior initiation stage, combating habit rejection stage, and habit acquisition and maintenance stage.Established theories of health behavior change mainly focus on the conflict between the goal-directed behavior initiation phase and habitual behavior.It is also indicated that disgust is the key mechanism to restrain the implementation of goal-oriented behavior, but ignore the mechanisms in the action implementation and new behavior acquisition phases.In fact, goal-directed and habitual behaviors work together to ensure that individuals adapt efficiently to their environment.However, when goal-oriented behavior becomes habitual, old habit and new goal-oriented behavior begin to compete, causing conflicts and aversion.The core phase of self-control functioning is just in the confrontation with habit rejection phase.On the one hand, self-control directly assists individual goal-directed behavior habituation through conflict sense adaptation.On the other hand, intensive management and stimulus control indirectly assist goal-directed behavior habituation through the relief of conflict sense.Further exploration of the theory and clinical practice of self-control affecting healthy behavior change is needed in the future.

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.

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.

Objective: To observe the effects of blueberry and nuclear expression of transcription factor-кb (NF-кb) p65 in an experimental rat model of liver fibrosis. Methods: Forty-five Sprague-Dawley rats were randomly divided into isotonic saline control group (A); model group (B); blueberry juice prevention group (C, 15 g/kg); dan-shao-hua-xian capsule prevention group (D, 1 g/kg); and blueberry juice + dan-shao-hua-xian capsule prevention group (E). Rat liver fibrosis model was established by covalent compound carbon tetrachloride (CCl₄). Each prevention group was given the corresponding dose of blueberry juice or (and) dan-shao-hua-xian capsule, and the rats were sacrificed after 8 weeks. The degree of liver fibrosis was evaluated by hematoxylin and eosin stain. A liver tissue of NF-κBp65 was detected by immunohistochemical method. The NF-κBp65 protein expression of liver tissue and transforming growth factor (TGF) β1 was detected by Western blot. Data of multiple groups were compared by one-way analysis of variance, and rank sum test. Results: Immunohistochemistry detected that TGFβ1 protein was mainly expressed in mesenchymal origin of hepatic stellate cells. The expression level of group A (3.75 ± 1.67) was low, while those of group B (9.00 ± 2.07), C (7.33 ± 1.00), D (6.00 ± 1.51), and E (3.5 ± 1.41) were high. However, the expression level of TGF-β1 protein in hepatic tissues of group B was significantly higher than that of group C, D and E [group E: 3.5 ± 1.41, F = 18.350, P < 0.05]. In addition, group D was higher than group E (P < 0.05). The expression of NF- kappa Bp65 protein was very complex, and the expression patterns in different groups were different (Statistical calculation of experimental data were based on expression of liver cells). Compared with group B (4.37 ± 2.13), the relative expression levels of NF-κBp65 protein in-group A (0.46 ± 0.25), group C (2.76 ± 1.01), group D (2.13 ± 1.51), group E (1.88 ± 0.99) were significantly decreased (F = 27.490, P < 0.05), and the expression trend was consistent with TGFβ1 protein. Western blot detected NF-κBp65 protein in liver tissues of rats. Compared with group A, levels in groups B, C, D and E were significantly increased (F = 96.983, P < 0.05), and groups C, D and E were significantly lower. The E group was significantly lower than the C group (F = 96.983, P < 0.05), and the degree of hepatic fibrosis was lower in each prevention group than in the B group (T = 24.1, P < 0.05). Conclusion Blueberries have preventive effect on CCl4-induced hepatic fibrosis in rats, and its preventive mechanism may inhibit the expression and activation of NF-κBp65 in hepatocytes, thereby reducing TGFβ1- mediated production or activation.

Objective: To observe the efficacy and safety related measures by blocking mother-to-child transmission of hepatitis B virus with high viral load and HBeAg positivity during pregnancy in Guizhou province. Methods: Outpatient and inpatient cases of the Department of Infectious Diseases and Obstetrics of Guizhou Medical University Affiliated Hospitals from May 2016 to July 2017 were retrospectively divided into intervention group, non-intervention group and non- hepatitis B pregnant women group; with 75 cases in each group. HBsAg and HBeAg were positive in the intervention group. Pregnant women with HBV DNA ≥10⁶ IU/ml were treated with anti-HBV therapy for 24 to 28 weeks of gestation until delivery. According to oral drugs, they were divided into tenofovir (TDF) group or telbivudine (LDT) group, non-intervention group (HBsAg and HBeAg positive), HBV DNA positive pregnant women, pregnant women with no anti-HBV drugs, non-hepatitis B pregnant women (normal pregnant women without HBV infection). Infants and young children born to the three groups of women were immunized with the national viral hepatitis B action plan. The gestational weeks and Apgar scores at birth, delivery mode, feeding mode, sex and 7-months-old age were observed and counted. Serum hepatitis B markers (HBVM) and HBV DNA were quantitatively detected. HBVM was detected by time-resolved fluorescence immunoassay (TRFIA), and HBV DNA was detected by real-time PCR (FQ-PCR). The changes of liver parameters, HBsAg, HBeAg, HBV DNA, adverse drug reactions and treatment response of pregnant intervention group before medication (12-24 weeks of gestation), 4 weeks of medication (28-32 weeks of gestation), 36-40 weeks of gestation (36-40 weeks of gestation) were statistically calculated. A t-test was used to compare the data between the measurements. Data measurements within the groups were analyzed using rank -sum test. Results: In the intervention group, therapeutic medications showed no differences in demographic and clinical characteristics between TDF group and LDT group, including liver parameters, HBsAg, HBeAg and log10HBV DNA level. Compared with pre-treatment (TDF group: 4.84 ± 2.01; LDT group: 5.08 ± 1.99), TDF and LDT were significantly lower at the end of pregnancy (TDF group: 3.06 ± 0.66; LDT group: 3.51 ± 1.20). P < 0.05); and the treatment response rate was 100%. There were no serious adverse events in the intervention group. Infants and young children (7-months-old) in the intervention group had negative HBsAg, HBeAg and HBV DNA. The mother-to-child transmission rate of HBV was zero, with blocking rate of 100%. In addition, both infants and young children had different degrees of hepatitis B protective antibodies (anti-HBs, M: 144.33), and their antibody titers were higher than that of non-intervention group (anti-HBs, M: 65.91) and non-hepatitis B pregnant women (anti-HBs, M: 58.43). The difference was statistically significant (P < 0.05), and there was no significant correlation between the use of antiviral and the way of delivery and feeding. Outcomes of mother-to-child transmission of HBV infection in infants and young children (7-months-old) delivered by three groups of pregnant women in the non-intervention groups had 20.0% (15/75)/ 17.3% (13/75) HBsAg/HBeAg positivity rate, and 17.3% (13/75) HBV DNA positivity rate. Overall, mother-to-child transmission rate of HBV infection was 20% (15/75). Furthermore, the relationship between mother's HBV DNA load and infant HBV infection in the non-intervention group showed mother's HBV DNA ≥10⁶ IU/ml. Conclusion In the non-intervention group, mother-to-child transmission of HBV occurred, and infected mothers HBV DNA was ≥106 IU/ml before delivery. This suggests that HBeAg positive and high load HBV DNA replication were independent risk factors for mother-to-child transmission of hepatitis B. Therefore, prenatal drug intervention and postpartum standard immune blockade are necessary for high-risk pregnant women with hepatitis B to achieve zero mother-to-child transmission of hepatitis B in real- clinical practice.

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.

AIM:To discover the effect of MCPH1 on the DNA damage induced by ionizing radiation in esoph-ageal cancer cells.METHODS:ECA109 cancer cells were radiated at dose of 8 Gy.The nuclear foci of relevant factors were detected 1 h after irradiation in the ECA109 cells after silence of MDC1 gene.A cell line was established that was sta-ble low expression of MCPH1.The nuclear foci induced by ionizing radiation after silence of MCPH1 were determined.RE-SULTS:The MCPH1 gene silenced ECA109 cell line was successfully constructed.A strong relationship between MDC1, MCPH1 andγ-H2AX was observed 1 h after 8 Gy irradiation.Silence of MDC1 did not affect the nuclear foci formation ofγ-H2AX and MCPH1.The nuclear foci of MDC1 but notγ-H2AX significantly reduced after silencing of MCPH1.CON-CLUSION:MCPH1 is located in the downstream of H2AX and upstream formation of MDC1, and regulates the nuclear fo-ci formation of MDC1 during DNA damage response.
