Objective: To study the relations between neck/shoulder or low back pain and their daily behavioral habits among middle school students in Shenzhen. Methods: We randomly chose 3 952 students from 10 high schools in Shenzhen to complete the questionnaires. Data was gathered and analyzed, using the IBM SPSS 23.0. Results: Of the 3 952 participants, 20.3% had neck/shoulder pain and 15.2% had low back pain. Among students experienced neck/shoulder pain, female (25.3%), high school (24.5%) and boarding students (24.4%) experienced higher rates of neck/shoulder pain (P<0.05). Female students (17.9%) also had higher rate of low back pain (P<0.05). Results from logistic regression analysis showed that factors as: gender, type of school, taking naps on the desk, staying up late, self-perceived stress from learning, overloading homework, time spent on mobile phone and TV, spending long time on computer etc. were related to the neck/shoulder pain (P<0.05). Factors as: gender, naps on the desk, stay up late, self-perceived stress, overloading homework, time spent on mobile phone and TV etc., were related to low back pain (P<0.05). Conclusion: Neck/shoulder pain and low back pain were both commonly seen while high self-perceived stress, sedentary behaviors and poor sleeping habits were associated with both neck/shoulder and low back pain in high school students in Shenzhen.

Objective: To identify the spatial clustering and its temporal trends among newly detected female HIV/AIDS cases aged 15 years or older, in China from 2010 to 2016. Methods: Newly detected HIV/AIDS cases among aged 15 years or older women in China during 2010-2016 were collected, to describe their demographic characteristics, changing trends and spatial autocorrelation. This program was conducted at county level, using the ArcGIS 10.3. Results: The number of newly detected HIV/AIDS cases among aged 15 years or older women was increasing annually from 16 603 to 26 196 in 2010 and in 2016. As the main route proportion of heterosexual transmission increased from 84.25% (13 988/16 603) in 2010 to 96.29%(25 224/26 196) in 2016. Both the number and proportion of HIV/AIDS cases among elderly women ≥50 years of age increased significantly from 17.82%(2 959/16 603) to 38.10%(9 981/26 196) in 2016. Results from spatial analysis demonstrated a county-level clustered distribution of HIV/AIDS cases across the country with a rising global Moran's I value=0.55 over the years (Z=51.46, P<0.001), which was concentrating on western and southern China, covering 9 provinces/autonomous regions/municipalities (Yunnan, Guangxi, Sichuan, Xinjiang, Guizhou, Guangdong, Chongqing, Henan and Hunan). The temporal trends of hot spots differed by age groups, with the trend of epidemic shifting towards western border and southern coastal regions among women aged 15-49 years old, while the elderly women aged ≥50 years old were spreading northward from the southwestern regions. Conclusion: Our findings indicated that an increasing trend of clusters appeared on HIV epidemic among newly detected female HIV/AIDS cases aged 15 years or older in China, particularly in the western and southern regions. Prevention and intervention strategies should target on women according to their age distribution, particularly in regions with increasing trend of HIV epidemics.

Objective: To understand the prevalence of major human parasitic diseases and related factors in Henan province. Methods: This stratified sampling survey was carried out according to the requirement of national survey protocol of major human parasitic diseases, 2014-2015. The prevalence of soil-transmitted helminths infection, taeniasis and intestinal protozoiasis were surveyed in 104 sites selected from 35 counties (districts) and the prevalence of clonorchiasis was surveyed in 62 sites selected from 37 townships. In each survey spot, 250 persons were surveyed. A total of 26 866 persons and 15 893 persons were surveyed. Modified Kato-Katz thick smear was used to detect the eggs of intestinal helminthes. Tube fecal culture was used to identify the species of hookworm. The Enterobius eggs were detected in children aged 3 to 6 years by using adhesive tape. The cyst and trophozoite of intestinal protozoa were examined with physiological saline direct smear method and iodine stain method. Results: The overall infestation rate of intestinal parasites was2.02% in Henan, and the worm infection rate was higher than protozoa infection rate. Fourteen kinds of intestinal parasites were found, including nematode (5 species), trematode (2 species), and protozoan (7 species). The infection rate of Enterobius vermicularis was highest, and Qinba Mountain ecological area had the highest infestation rate of intestinal parasites in 4 ecological areas of Henan. There was no significant difference in intestinal parasite infection rate between males and females (χ(2)=3.630, P=0.057), and the differences in intestinal parasite infection rate among different age groups had significance (χ(2)=124.783, P=0.000 1). The infection rate reached the peak in age group ≤9 years and the major parasite was Enterobius vermicularis. Furthermore the overall human infection rate of parasite showed a downward trend with the increase of educational level of the people (χ(2)=70.969, P=0.000 1), the differences had significance (χ(2)=120.118, P=0.000 1). For different populations, the infection rate of intestinal parasites was highest among preschool children. The infection of intestinal helminth was mainly mild, only 2 severe cases were detected. The infection rate of Clonorchis sinensis in urban residents was only 0.006%. Logistic regression analysis showed that being preschool children (χ(2)=15.765, P=0.000 1) and drinking well water (χ(2)=45.589, P=0.000 1) were the risk factors for intestinal parasite infection, and annual income per capita of farmers was the protective factor against intestinal parasite infection. The infection rates of protozoa and intestinal parasites decreased sharply compared with the results of previous two surveys, and the rate of intestinal helminth infection also dropped sharply compared with the second survey. The numbers of protozoa, helminth and intestinal parasites detected in this survey were all less than the numbers found in the previous two surveys. Conclusions: Compared the results of three surveys in Henan, the infection rate of protozoa and intestinal parasites showed a downward trend. The prevention and treatment of Enterobius vermicularis infection in children should be the key point of parasitic disease control in the future.

Objective: To understand the survival of HIV/AIDS patients after receiving antiretroviral therapy for 10 year in Henan province and related factors. Methods: The database of national integrated management system of HIV/AIDS was used to collect the basic information and follow-up information of HIV/AIDS patients who received antiretroviral therapy between 2003 and 2005 in Henan province. Software SPSS 23.0 was used to analyze the patients' survival and related factors based on the life-table method and Cox proportional hazards model. Results: Among the 2 448 HIV/AIDS patients who started antiretroviral therapy during 2003-2005, the men accounted for 53.5%, and women accounted for 46.5%. Up to 70.1% of the patients were aged 40-59 years and 95.5% of the patients had blood borne infections. The patients were observed for 10 years after antiviral treatment, and 719 cases died from AIDS related diseases, with a mortality rate of 3.78/100 per year (719/19 010 per year). The cumulative survival rates of patients within 1-year, 3 years, 5 years and 10 years were 0.94, 0.86, 0.78, 0.69 respectively. Compared with the patients aged <40 years, the HRs of the patients aged 40-, 50-, 60- and ≥70 years were 1.417 (95%CI: 0.903-2.222), 1.834 (95%CI: 1.174-2.866), 2.422 (95%CI: 1.539-3.810) and 3.424 (95%CI: 2.053-5.709) respectively. Compared with patients with baseline CD(4+)T lymphocyte >350 unit/ul, the HRs of the patients with CD(4+)T lymphocyte <50 unit/μl, 50-199 unit/ul and 200-350 unit/ul were 7.105 (95%CI: 5.449-9.264), 4.175 (95%CI: 3.249-5.366) and 2.214 (95%CI: 1.691-2.900) respectively. Compared with the women, the HR of the men was 1.480 (95%CI: 1.273-1.172). Compared with the patients who received second line ART therapy, the HR of patients receiving no second line therapy was 11.923 (95%CI: 9.410-15.104). Conclusions: The cumulative survival rate the HIV/AIDS patients after 10 years of antiretroviral therapy reached 0.69 in Henan. Male, old age, low basic CD(4+)T lymphocyte count and receiving no second line therapy were the risk factors for long-term survival of AIDS patients.

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 study the lineages of rabies virus and the epidemic characteristics in different provincial populations of China, to provide information for the development of control and prevention measures in each respective provinces. Methods: Full length N and G genes and full-genome of epidemic strains of rabies virus collected in China were downloaded from GenBank and combined with newly sequenced strains by our lab. Each strain was classified under six lineages of China rabies by constructing phylogenetic trees based on the N or G sequences. Numbers of strains and lineages in each province were counted and compared. Results: Six lineages (China Ⅰ-Ⅵ) were prevalent in China, with 4 found in Yunnan and Hunan. In 6 provinces, including Henan and Fujian, 3 lineages were found. In 8 provinces, including Shanghai and Jiangxi, 2 lineages were found Only 1 lineage, were found in Beijing, Tianjin and other 12 provinces. the China Ⅰ, was the dominant one in 25 provinces. In recent years, China Ⅲ had been found in wild animals and spread over livestock in Inner Mongolia and Xinjiang areas. Qinghai and Tibet had been influenced by China Ⅳ, which also been found in wild animals of Inner Mongolia and Heilongjiang. Conclusion: There had been obvious differences in lineages and strain numbers of rabies virus identified in different provinces in China.

Objective: To explore the effect of influenza and 23 valent pneumococcal polysaccharide pneumococcal vaccinations on symptom-improvement among elderly with chronic obstructive pulmonary diseases (COPD). Methods: Data was gathered from 4 communities in 3 National Demonstration Areas set for comprehensive prevention and control of chronic non- communicable diseases in Chongqing city and Ningbo city respectively, from November 2013 to October 2014. The communities were selected by cluster sampling and divided into 4 groups: (1) injected influenza vaccines; (2) injected with pneumococcal vaccines; (3) received both of the two vaccines; (4) the control group that without any intervention measures. All the subjects aged from 60 to 75 were selected to fill in demographic information questionnaire and receive (COPD assessment test, CAT) scores twice, before intervention and 1 year after the vaccination. SAS 9.4 software was used to analyze the change of symptoms and CAT scores before and after the intervention program and comparing the improvement on symptoms among the elderly people under study. Results: A total of 1 244 subjects with nearly same baseline conditions after the propensity score matching, were involved in this study. CAT scores appeared as Median=21 (IQR: 17-26) at baseline. The CAT scores appeared as Median=18 (IQR: 14-24), decreasing in all the 3 vaccinated groups, one year after the intervention program (influenza vaccines, matching t test, t=-6.531, P=0.403; pneumococcal vaccines, Wilcoxon test, H=-9 623, P<0.001; combined vaccine vaccines, matching t test, t=-10.803, P<0.001). However, in the control group, no obvious change was observed (Wilcoxon H=1 167, P=0.403). Proportions of impacts at high or very high levels all decreased in the 3 intervention groups, while little change was observed in the control group. Outcomes from the Factorial analysis suggested that influenza vaccination could improve the general conditions and symptoms including cough, chest tightness, dyspnea, physical activities, and stamina. Pneumococcal vaccination appeared more effective on all of symptoms and indicators. Conclusion: Pneumococcal and influenza vaccination seemed helpful for elderly people suffering COPD to improve the general health condition.

Objective: To investigate the clinical pathology and gene mutation characteristics of patients with glycogen storage disease type Ⅳ (GSD Ⅳ). Methods: The clinical data, liver histopathology and ultrastructural morphology, and gene sequencing results of 5 GSD Ⅳ cases diagnosed in the Children's Hospital Affiliated to Shanghai Jiaotong University School of Medicine and the Children's Hospital of Fudan University from January 2015 to February 2022 were collected and analyzed retrospectively. Results: Among the 5 cases, 3 were male and 2 were female, ranging in age from 4 months to 1 year and 9 months. The clinical manifestations included fever, hepatosplenomegaly, liver insufficiency, growth retardation and hypotonia. Four cases had liver biopsy showing ground-glass-like changes in hepatocytes with intracytoplasmic inclusion bodies and varying degrees of fibrosis. Liver electron microscopy in 2 cases showed that the level of glycogen increased to varying degrees, and the cytoplasm was filled with low electron density substances. Genetic testing revealed that 3 cases had compound heterozygous variants in GBE1 gene; 1 case had a single pathogenic variant in GBE1 gene; and 1 case was deceased with no genetic testing, but each parent was tested for a heterozygous variant in the GBE1 gene. A total of 9 GBE1 gene mutations were detected, 3 of which were reported mutations and 6 novel mutations. One case died of liver cirrhosis, and 1 case underwent autologous liver transplantation. After transplantation, the liver function basically returned to normal, and the growth and development improved; the other 3 cases were managed through diet control and symptomatic treatment. Conclusions: CSD Ⅳ is an extremely rare inherited metabolic disease caused by GBE1 gene mutation, often presenting with hepatic and neuromuscular disorders, with heterogeneous clinical manifestations. The diagnosis mainly depends on histopathology and a pedigree gene analysis.
