Introduction Violence is defi ned by the WHO as “the intentional use of physical force or power, threatened or actual, against oneself, another person, or against a group or community, which either results in or has a high likelihood of resulting in injury, death, psychological harm, maldevelopment, or deprivation”. Violence can be divided into many types such as physical, psychological, sexual, neglect and economical etc. Violence against women and child is a manifestation of historically unequal power relations between men and women or child due to patriarchy in many countries of the world. Child maltreatment or violence is one of common public health problems in worldwide and psychologically harm in child’s later life. Objective To detect types, percent and some infl uencing factors of violence against child and adolescent among cases, which were involving into forensic psychiatric evaluation procedures. Materials and Methods We are analyzed all archive documents of NCMH, 2000-2014 by retrospective methodology on based ethical approval of NCMH administration (by ordering 2/189 Oct 28, 2015). Results Total 1067 cases of violence against child and adolescent were registered in 2000-2014 years and 84.7 percent of those (n=904) were sexual violence cases. Gender difference was defi ning among sexual violence cases (girls n=885, p<0.000; boys n=19, p<0.000) with statistically signifi cant. Sexual offender can be act his violence in drunken (OR=2.355; p<0.000; CI 95%; 1.601-3.463) or negative relationship between family members (OR=3.723; p<0.000; CI 95%-2.356-5.883) are more infl uenced to sexual violence against child and adolescent. Conclusion Sexual violence is more registered among child and adolescent maltreatment cases. Children and adolescents are more affected into sexual violence likely to have a negative relationship between the family members or offenders have used alcohol.

In the studies of modern epidemiology, exposure in a short term cannot fully elaborate the mechanism of the development of diseases or health-related events. Thus, lights have been shed on to life course epidemiology, which studies the exposures in early life time and their effects related to the development of chronic diseases. When exploring the mechanism leading from one exposure to an outcome and its effects through other factors, due to the existence of time-variant effects, conventional statistic methods could not meet the needs of etiological analysis in life course epidemiology. This paper summarizes the dynamic path analysis model, including the model structure and significance, and its application in life course epidemiology. Meanwhile, the procedure of data processing and etiology analyzing were introduced. In conclusion, dynamic path analysis is a useful tool which can be used to better elucidate the mechanisms that underlie the etiology of chronic diseases.

Objective: To investigate the infection pattern and etiological characteristics of a case of human infection with highly pathogenic avian influenza A (H7N9) virus and provide evidence for the prevention and control of human infection with highly pathogenic avian influenza virus. Methods: Epidemiological investigation was conducted to explore the case's exposure history, infection route and disease progression. Samples collected from the patient, environments and poultry were tested by using real time reverse transcriptase-polymerase chain reaction (RT-PCR). Virus isolation, genome sequencing and phylogenetic analysis were conducted for positive samples. Results: The case had no live poultry contact history, but had a history of pulled chicken processing without taking protection measure in an unventilated kitchen before the onset. Samples collected from the patient's lower respiratory tract, the remaining frozen chicken meat and the live poultry market were all influenza A (H7N9) virus positive. The isolated viruses from these positive samples were highly homogenous. An insertion which lead to the addition of multiple basic amino acid residues (PEVPKRKRTAR/GL) was found at the HA cleavage site, suggesting that this virus might be highly pathogenic. Conclusions: Live poultry processing without protection measure is an important infection mode of "poultry to human" transmission of avian influenza viruses. Due to the limitation of protection measures in live poultry markets in Guangzhou, it is necessary to promote the standardized large scale poultry farming, the complete restriction of live poultry sales and centralized poultry slaughtering as well as ice fresh sale.

Objective: To explore the SNP effects of patatin-like phospholipase domain which containing 3 (PNPLA3), transmembrane 6 superfamily member 2 (TM6SF2) gene, environmental effects of smoking, alcohol drinking and interaction between gene-gene, gene-environment and drinking-smoking on hepatitis B virus-associated hepatocellular carcinoma (HBV-HCC). Methods: We collected anticoagulant peripheral blood from patients of HBV-HCC, chronic hepatitis B (CHB), liver cirrhosis (LC) and from healthy controls to detect the single nucleotide polymorphism (SNP) of patatin-like phospholipase domain containing 3 (PNPLA3) gene loci rs738409 and transmembrane 6 superfamily member 2 (TM6SF2) gene loci rs58542926, using the flight mass spectrometry method. The optimal assignment value of gene polymorphisms was defined by using the online SNP stats. Hardy-Weinberg (H-W) balance was tested for SNP. Effects of the genetic and environmental factors to HBV-HCC were analyzed by using the multiple classification logistic regression method. The gene-gene, gene-smoking and alcohol drinking interaction effects were investigated by Fork-Life analysis and binary logistic regression methods. Results: The frequency distribution of CHB group rs738409 loci seemed not in conformity with the H-W balance (χ(2)=11.980, P<0.005). Two loci frequency distributions in the other groups were all in accordandce with the H-W balance. After adjusting for influences on age and sex and comparing to the healthy group, the rs58542926 mutation appeared as OR=1.659, 95%CI: 1.026-2.684, P=0.039, in the HBV-HCC group. When comparing to CHB group, the HBV-HCC group presented that drinking as OR=1.680, 95%CI: 1.121-2.519, P=0.012. When comparing to the LC group, the ORs of drinking and smoking were 1.539 (1.071-2.213) and 1.453 (1.005-2.099) respectively, in the HBV-HCC group. When comparing to the CHB+LC group, interactions between the HBV-HCC group were found rs738409 and rs58542926 on additive model OR=1.548 (U=1.885, P=0.029) and OR=1.658 (P=0.024) on logistic regression model while drinking was rs738409 on interaction additive model with OR=1.811(U=1.965, P=0.024). As for drinking and mutation of rs738409, the multiplication model of logistic regression showed no statistically significant differences. Interaction between smoking and drinking appeared as OR=1.756 (P<0.001) in the logistics regression multiplication model. Conclusions: Factors as mutation of TM6SF2, smoking and drinking all appeared as risk factors for HBV-HCC. Mutations of both PNPLA3 and TM6SF2, together with smoking and drinking all served as risk factors for HBV-HCC. However, the mutation of single PNPLA3 appeared as a protective factor on HBV-HCC.

OBJECTIVETo investigate the impact of novel P2Y(12) receptor inhibitors including prasugrel or ticagrelor on platelet reactivity in patients with acute coronary syndrome (ACS) receiving percutaneous coronary intervention (PCI), and provide clinical data for novel oral P2Y(12) receptor inhibitors use among Chinese patients.

METHODSBetween October 2011 to February 2014, 174 consecutive patients (135 males; (67.8±11.8) years old) with ACS undergoing PCI in Kiang Wu Hospital, Macau were prospectively enrolled in this study. Oral aspirin and one P2Y(12) receptor inhibitor were administered for 5 days or above after PCI, patients were divided into clopidogrel, prasugrel and ticagrelor groups in accordance with the agent administered. Platelet reactivity of the patients was detected by VerifyNow P2Y(12) reaction unit (PRU); and the high on-treatment platelet reactivity (HPR) and non-HPR were defined as PRU≥208 and PRU<208 respectively. Patients with HPR during clopidogrel therapy were switched either to prasugrel or ticagrelor, or continued the same treatment; and then the platelet reactivity was monitored again.

RESULTSThere were 113 clopidogrel cases (64.9%), 20 prasugrel cases (11.5%) and 41 ticagrelor cases (23.6%). Fifty-seven cases (32.8%) were defined as HPR post P2Y(12) receptor inhibitor use, in which 55 cases (55/113, 48.7%) were treated with clopidogrel. The degree of inhibition of platelet reactivity was significantly different in patients on clopidogrel, prasugrel and ticagrelor therapy, percent inhibition assayed by the VerifyNow P2Y(12) system was 28.2%±23.5%, 61.4%±26.7% and 81.3%±19.8% respectively (P<0.05). Different degree of platelet reactivity was achieved by the 3 P2Y(12) receptor inhibitors at multiple time points. The among-group differences in platelet reactivity became apparent at the early treatment stage (P<0.05). Platelet aggregation decreased significantly in patients switched from clopidogrel to prasugrel or ticagrelor (P<0.05).

CONCLUSIONNovel oral P2Y(12) receptor inhibitors are more effective in inhibiting platelet reactivity in ACS patients, and our results show that novel oral P2Y(12) receptor inhibitors provide a new option for ACS patients with HPR post clopidogrel or high-risk features of ischemic complications, including stent thrombosis and post-PCI ischemic events.

Objective: To analyze the mortality and years of life lost (YLL) trends of cervical cancer in Tianjin, and provide references for the research and prevention programs of cervical cancer. Methods: Mortality rate, standard mortality rate, cumulative rate (0-74 years-old) and truncated rate (35-64 years-old) of cervical cancer from 1999 to 2015 were calculated. The annual percentage change of the mortality rate and YLL rate were analyzed by using Joinpoint regression analysis, and the trend in different age-groups were analyzed. Results: From 1999 to 2015, 1 741 cases died of cervical cancer in Tianjin, the average crude mortality rate was 2.15/100 000. The average age-standardized rate of (ASR) China and ASR world were 1.47/100 000 and 1.50/100 000 respectively. The average YLL was 3 347.97 person-years. Deaths occurred in those aged 0-34 years, 35-64 years and 65 years and over accounted for 3.10%, 57.84% and 39.06% of the total, respectively. The mortality rate of cervical cancer in urban area was higher than that in rural area, with a ratio of 1.37∶1 between urban area and rural area. The age-specific mortality rate of cervical cancer during 1999-2015 increased with age. Two peaks of mortality rate were observed in those aged 50 years and aged 75 years, during 2014-2015. From 1999 to 2011, the mortality rate of cervical cancer was stable (APC=-0.2%, P=0.80), but there was a rapid increase from 2011 to 2015 (APC=21.6%, P<0.01). But group aged 20-49 years, it showed an upward trend from 1999 to 2015 (APC=6.9%, P<0.01). For group aged 50-69 years, it showed a downward trend from 1999 to 2007 (APC=-9.2%, P<0.01), and an upward trend from 2007 to 2015 (APC=14.5%, P<0.01). For group aged 70 years and over, it showed a downward trend from 1999 to 2009 (APC=-10.2%, P<0.01), but the difference in the mortality were not significant from 2009 to 2015 (APC=7.8%, P=0.10). Since 2008, the YLL rate of cervical cancer in group aged 50-70 years had exceeded that in group aged >70 years and the gap gradually widened. Conclusions: There had been a rapid increase trend of cervical cancer mortality since 2011 in Tianjin. Women aged 50-70 years were the main group of life loss.

Objective: To investigate the effect of heterogeneous nuclear ribonucleoprotein K (hnRNP K) and its interaction with human papillomavirus 16 (HPV16) on cervical intraepithelial neoplasia (CIN). Methods: The participants included 67 women with normal cervix (NC), 69 women with CINⅠ and 68 women with CINⅡ/Ⅲ in a community cohort of pathologically diagnosed women established in Jiexiu of Shanxi province, from June 2014 to June 2015. A structured questionnaire was used to collect the demographic data of the subjects and the related factors of cervical lesions. Cervical exfoliated cells and cervical tissues from biopsy or surgery were selected. The infection status of HPV16 was detected by flow-through hybridization. The protein expression levels of hnRNP K were evaluated by Western blot. SPSS 23.0 software was used to collate and analyze the data. To study the differences in demographic characteristics, related factors, hnRNP K protein and HPV16 infection among NC, CINⅠand CINⅡ/Ⅲgroups, χ(2) test, trend χ(2) test, and Kruskal-Wallis H test were conducted. Multiple comparisons of hnRNP K protein in three groups were completed by using the Bonferroni method. The OR and its 95%CI of hnRNP K, HPV16 and CIN were calculated by using the unconditional logistic regression models. Two-way interactions between hnRNP K protein and HPV16 infection on CIN were analyzed by using additive model and related indicators. Results: HPV16 infection rates were 10.4% in women with normal cervix, 14.5% in women with CINⅠ and 41.2% in women with CINⅡ/Ⅲ, respectively. The differences among three groups were significant (P<0.001). Moreover, the infection rates of HPV16 gradually increased with the increasing severity of CIN (trend χ(2)=18.512, P<0.001). The differences in protein expression of hnRNP K among three groups were significant (H=48.138, P<0.001) and the expressionincreased with the development of cervical lesionss (trend χ(2)=21.765, P<0.001). Results from the interaction analysis indicated that there were additive effects between high expression of hnRNP K protein and HPV16 in CINⅡ/Ⅲ group compared with normal group (API=0.639, 95%CI: 0.083-1.196). In contrast, no such additive effect was found in CINⅠ group. Conclusions: HPV16 infection and over-expression of hnRNP K protein were associated with the increased risk of cervical intraepithelial neoplasia. There might be interaction between hnRNP K protein overexpression and HPV16 infection existed on the progress of CINⅡ/Ⅲ.

OBJECTIVETo obtain the polymorphic data of short tandem repeat(STR) loci of D15S657, D11S1369, D6S2420 and D6S503 in Chinese Han population and to study the association of these four STR loci with insulin-dependent diabetes mellitus(IDDM).

METHODSThe polymorphisms of the four STRs were studied by polymerase chain reaction-polyacrylamide gel electrophoresis(PCR-PAGE) followed by direct sequencing of PCR products in 105 normal Chinese Hans and 48 patients with IDDM.

RESULTSSeven alleles at D15S657 locus, 5 alleles at D11S1369 locus, 7 alleles at D6S2420 locus and 4 alleles at D6S503 locus were found. No deviation from Hardy-Weinberg equilibrium was observed. The heterozygosities of these loci were 0. 7524, 0.6000, 0.6286, 0.6571 and the polymorphic information contents(PIC) 0.7616, 0.4430, 0.5345 and 0.5932, respectively. The allele frequencies of allele A(5) at D15S657 locus, allele A(5) at D11S1369 locus and allele A(4) at D6S2420 locus were increased significantly in patients with IDDM, compared to those in the control group.

CONCLUSIONThe four STRs, used as genetic markers, were suitable for case-control study, forensic medicine identification and population genetic study. There is an association between the polymorphisms of D15S657, D11S1369, D6S2420 and IDDM.

Objective: To understand the epidemiological and etiological characteristics of mumps in Fujian province, 2005-2017. Methods: All the reported mumps cases were collected through the National Notifiable Disease Information Management System, 2005-2017. Active search and interviews were conducted to collect the information on vaccination of mumps. Throat swab specimens were collected for cells culture, genotyping and gene sequence analysis on mumps virus (MuV). Results: A total of 83 959 cases of mumps were reported in Fujian province from 2005 to 2017, with an average annual incidence of 17.6 per 100 000. Since 2007, the incidence appeared increasing but then decreasing, reaching the lowest level (7.5 per 100 000), after the setup of a monitoring program. Annually, the onset time of mumps showed an obvious two seasonal peaks, one from April to July, with a weakening trend, and the other from October to January with a rising trend. Most of the mumps cases occurred among students, kindergarten and scattered children (89.2%, 5 814/6 517), children aged 5-9 years (38.8%, 2 527/6 517), with cases reported from every region. Program from the pathogen surveillance showed that the transmission chain of G genotype mumps virus did exist in Fujian. Data from the sequence analysis revealed that mutations in the nucleotide of G genotype strain in 2015 had led to mutation of 6 amino acid sites in the SH gene coding region, resulting in the differences appearing in both nucleotide and amino acid homology with type A vaccine strain. Conclusions: The incidence of mumps decreased annually, in Fujian. Prevention programs should focus on primary and secondary school students. In Fujian province, we also noticed the transmission chain of mumps G genotype with some amino acid mutations in the SH gene coding region. Monitor programs on both epidemiologic and etiology, should be strengthened.

Objective: To assess the implementation and impact of programs carried out by the National Demonstration Areas for Comprehensive Prevention and Control of Non-communicable Diseases. Methods: Both sociological and epidemiological methods were used to collect qualitative and quantitative data in November and December, 2016 in order to conduct on process and outcome evaluation of the above mentioned objective. In the meantime, case study was also conducted. Results: All the National Demonstration Areas for Comprehensive Prevention and Control of Non-communicable Diseases were found well implemented across the country, with health education and health promotion, surveillance and safeguard measures in particular. A government-led and inter-sector coordination and communication mechanism had been well established, with more than 16 non-health departments actively involved. 28.7% of the residents living in the National Demonstration Areas for Comprehensive Prevention and Control of Non-communicable Diseases were aware of the key messages related to chronic diseases. Among the residents, 72.1% of them consumed vegetables and 53.6% consumed fruits daily, with another 86.9% walked at least 10 minutes per day. Over 70% of the patients with hypertension or diabetes reported that they were taken care of by the Community Health Centers, and above 50% of them were under standardized management. Residents, living in the National Demonstration Areas under higher ranking of implementation scores, were more likely to be aware of relevant knowledge on chronic disease control and prevention (OR=6.591, 95%CI: 5.188-8.373), salt reduction (OR=1.352, 95%CI: 1.151-1.589), oil reduction (OR=1.477, 95%CI: 1.249-1.746) and recommendation on physical activities (OR=1.975, 95%CI: 1.623- 2.403). Conclusion: The implementation of programs carried out by the National Demonstration Areas for Comprehensive Prevention and Control of Non-communicable Diseases had served a local platform for the control and prevention of non-communicable diseases, and thus become an important 'carrier' for chronic disease prevention and control programs in China.
