Abstract
Objective: To identify a novel reassortant H3N2 avian influenza virus using nanopore sequencing technology and analyze its genetic characteristics. Methods: The positive samples of the H3N2 avian influenza virus, collected from the external environment in the farmers' market of Guangzhou, were cultured in chicken embryos. The whole genome was sequenced by targeted amplification and nanopore sequencing technology. The genetic characteristics were analyzed using bioinformatics software. Results: The phylogenetic trees showed that each gene fragment of the strain belonged to the Eurasian evolutionary branch, and the host source was of avian origin. The HA gene was closely related to the origin of the H3N6 virus. The NA gene was closely related to the H3N2 avian influenza virus from 2017 to 2020. The PB1 gene was closely related to the H5N6 avian influenza virus in Guangxi Zhuang Autonomous Region and Fujian Province from 2016 to 2022 and was not related to the PB1 gene of the H5N6 avian influenza epidemic strain in Guangzhou. The other internal gene fragments had complex sources with significant genetic diversity. Molecular characteristics indicated that the strain exhibited the molecular characteristics of a typical low pathogenic avian influenza virus and tended to bind to the receptors of avian origin. On important protein sites related to biological characteristics, this strain had mutations of PB2-L89V, PB1-L473V, NP-A184K, M1-N30D/T215A, and NS1-P42S/N205S. Conclusions: This study identified a novel reassortant H3N2 avian influenza virus by nanopore sequencing, with the PB1 gene derived from the H5N6 avian influenza virus. The virus had a low ability to spread across species, but further exploration was needed to determine whether its pathogenicity to the host was affected.

Abstract
Objective: To understand the infection status and molecular types of rhinovirus (RV) among cases of Acute Respiratory Infections (ARIs) in Luohe City, Henan Province, from 2017 to 2022. Methods: From October 2017 to June 2022, clinical and epidemiological data were collected from 2 270 cases of ARIs at Luohe Central Hospital in Henan Province. Throat swab specimens were obtained from these cases. Real-time quantitative polymerase chain reaction (qPCR) was used to screen for RV-positive specimens. Subsequently, the positive samples were subjected to nested reverse transcription polymerase chain reaction (nested RT-PCR) to amplify the full-length VP1 region. Using the MEGA software, along with 169 RV reference strains recommended by the International Committee on Taxonomy of Viruses, a phylogenetic tree was constructed to determine RV types. Results: Among the 2 270 cases of ARIs, there were 1 283 male cases (56.52%). The median age (Q1, Q3) was 3 (1, 6) years, with the population under 5 years old accounting for 68.59% (1 557/2 270). RV was detected in 137 cases (6.04%), of which 68 cases (49.64%) showed co-detection with other viruses, with the most common being co-detection with enterovirus, accounting for 14.60% (20/137). The RV detection rates in the age groups of 0~4 years, 5~14 years, 15~59 years, and≥60 years were 6.42% (100/1 557), 4.69% (21/448), 3.80% (6/158), and 9.35% (10/107), respectively, with no statistically significant differences (χ2=5.310, P=0.150). The overall detection rates of RV before (2017-2019) and during (2020-2022) the COVID-19 pandemic showed no statistically significant difference (χ2=1.823, P=0.177). A total of 109 VP1 sequences were obtained, including 62 types. Among them, RV-A, RV-B, and RV-C had 42, 3, and 17 types respectively. Conclusion: RV is one of the predominant pathogens in ARIs cases in Luohe City, Henan Province, from 2017 to 2022. Multiple types of RV co-circulate without any apparent dominant type.

Abstract
Complement activation is thought to underline the pathologic progression of obesity-related metabolic disorders; however, its role in adaptive thermogenesis has scarcely been explored. Here, we identify complement C3a receptor (C3aR) and C5a receptor (C5aR) as critical switches to control adipocyte browning and energy balance in male mice. Loss of C3aR and C5aR in combination, more than individually, increases cold-induced adipocyte browning and attenuates diet-induced obesity in male mice. Mechanistically, loss of C3aR and C5aR increases regulatory T cell (Treg) accumulation in the subcutaneous white adipose tissue during cold exposure or high-fat diet. Activated Tregs produce adenosine, which is converted to inosine by adipocyte-derived adenosine deaminases. Inosine promotes adipocyte browning in a manner dependent on activating adenosine A2a receptor. These data reveal a regulatory mechanism of complement in controlling adaptive thermogenesis and suggest that targeting the C3aR/C5aR pathways may represent a therapeutic strategy in treating obesity-related metabolic diseases.

Abstract
Objective: To analyze the trust in vaccination and its influencing factors in parents of children aged 0-6 years. Methods: In June 2021, a cross-sectional survey was conducted to collect the basic information of parents of children aged 0-6 years, including their trust in vaccination and their attitudes towards vaccination. The χ2 test was used to compare the difference between different groups, and logistic regression was used to analyze the influencing factors. Results: A total of 10 916 parents of children aged 0-6 years were investigated in this study, and their trust in vaccine was 67.20%, of which safety (55.80%) was the key factor limiting the trust in vaccination. 37.94% (4 142/10 916) of the parents were willing to vaccinate more than two kinds of vaccines at the same time, and 85.07% (9 286/10 916) of the parents feared that abnormal reactions would occur after vaccination. The parents' age, education level and annual family income were the promoting factors of their trust in vaccination (P<0.05). Obtaining vaccine knowledge through vaccination APP or official account (OR=1.330, 95%CI: 1.188-1.489) and popular science leaflets distributed by vaccination clinics (OR=1.120, 95%CI: 1.020-1.228) were the promoting factors of parents' trust in vaccination. Young children and parents, high family income and education level were the promoting factors for parents to be willing to vaccinate at the same time (P<0.05), and young children and parents, low family income and education level were the inducing factors for fear of abnormal reaction after vaccination (P<0.05). Parents of children in the central region had a high acceptance of simultaneous vaccination for children, while parents of children in the western region had a low degree of concern about abnormal reactions after vaccination (P<0.05). Parents of children who read books and got vaccine knowledge online (OR=1.257, 95%CI: 1.153-1.371), urban residents (OR=1.173, 95%CI: 1.062-1.295) and with jobs (OR=1.109, 95%CI: 1.015-1.212) were more willing to vaccinate at the same time. The choice of imported vaccine was a promoting factor for parents to worry about abnormal reactions after vaccination (P<0.05). Conclusion: There is room for parents of children aged 0-6 years to further improve their trust in vaccination. At this stage, it is necessary to innovate the way of health education and health promotion, and pay attention to the publicity of vaccine safety knowledge, so as to improve parents' trust in vaccination.

Abstract
Objective: To understand the epidemiological characteristics of two local COVID-19 outbreaks caused by 2019-nCoV Omicron variant in Guangzhou, such as incubation period, serial interval, basic reproductive number (R0) and the influence of gathering places on R0, and provide evidence for the prevention and control of Omicron variant infection. Methods: The data of daily confirmed cases of Omicron variant infection from April 8 to May 8, 2022 in two COVID-19 outbreaks in Guangzhou were collected for model fitting. Weibull, Gamma and lognormal distribution were used to estimate incubation period and serial interval. Exponential growth method and the maximum likelihood estimation were used to estimate R0. Results: The median of incubation period was 2.94 (95%CI: 2.52-3.38) days and median of serial interval was 3.32 (95%CI: 2.89-3.81) days. The estimated R0 in small-size place was 4.40 (95%CI: 3.95-4.85), while the estimated R0 at airport was 11.35 (95%CI: 11.02-11.67). Conclusion: The incubation period of Omicron variant in two local COVID-19 outbreaks in Guangzhou is significantly shorter than that of delta variant. The higher the gathering degree in a place, the larger the R0. Due to its rapid transmission, COVID-19 epidemic is prone to occur. Therefore, the COVID-19 prevention and control strategy should be dynamically adjusted in time.

Abstract
Objective: To investigate the blood pressure change in patients with acute ischemic stroke (AIS) and hypertension treated with cinepazide maleate injection. Methods: This was a subgroup analysis of post-marketing clinical confirmation study of cinepazide maleate injection for acute ischemic stroke: a randomized, double-blinded, multicenter, placebo-parallel controlled trial, which conducted in China from August 2016 to February 2019. Eligible patients fulfilled the inclusive criteria of acute anterior circulation ischemic stroke with National Institutes of Health Stroke Scale (NIHSS) scores of 7-25. The primary endpoints were mean blood pressure of AIS patients treated with cinepazide maleate or control, which were assessed during the treatment period (14 days), and the proportion of the patients with normal blood pressure was analyzed after the treatment period. Furthermore, a subgroup analysis was performed to investigate a possible effect of the history of hypertension on outcomes. Results: This analysis included 809 patients with hypertension. There was no significant difference in patients blood pressure and the proportion of patients with normal blood pressure (60.5% vs. 59.0%,P>0.05) between cinepazide maleate group and control group. Conclusion: Administration of cinepazide maleate injection does not affect the management of clinical blood pressure in patients with AIS.

Abstract
BACKGROUND The ADRB3 (β3-adrenergic receptors), which is predominantly expressed in brown adipose tissue (BAT), can activate BAT and improve metabolic health. Previous studies indicate that the endocrine function of BAT is associated with cardiac homeostasis and diseases. Here, we investigate the role of ADRB3 activation-mediated BAT function in cardiac remodeling. METHODS BKO (brown adipocyte-specific ADRB3 knockout) and littermate control mice were subjected to Ang II (angiotensin II) for 28 days. Exosomes from ADRB3 antagonist SR59230A (SR-exo) or agonist mirabegron (MR-exo) treated brown adipocytes were intravenously injected to Ang II-infused mice. RESULTS BKO markedly accelerated cardiac hypertrophy and fibrosis compared with control mice after Ang II infusion. In vitro, ADRB3 KO rather than control brown adipocytes aggravated expression of fibrotic genes in cardiac fibroblasts, and this difference was not detected after exosome inhibitor treatment. Consistently, BKO brown adipocyte-derived exosomes accelerated Ang II-induced cardiac fibroblast dysfunction compared with control exosomes. Furthermore, SR-exo significantly aggravated Ang II-induced cardiac remodeling, whereas MR-exo attenuated cardiac dysfunction. Mechanistically, ADRB3 KO or SR59230A treatment in brown adipocytes resulted an increase of iNOS (inducible nitric oxide synthase) in exosomes. Knockdown of iNOS in brown adipocytes reversed SR-exo-aggravated cardiac remodeling. CONCLUSIONS Our data illustrated a new endocrine pattern of BAT in regulating cardiac remodeling, suggesting that activation of ADRB3 in brown adipocytes offers cardiac protection through suppressing exosomal iNOS.

Abstract
Obesity-induced secretory disorder of adipose tissue-derived factors is important for cardiac damage. However, whether platelet-derived growth factor-D (PDGF-D), a newly identified adipokine, regulates cardiac remodeling in angiotensin II (AngII)-infused obese mice is unclear. Here, we found obesity induced PDGF-D expression in adipose tissue as well as more severe cardiac remodeling compared with control lean mice after AngII infusion. Adipocyte-specific PDGF-D knockout attenuated hypertensive cardiac remodeling in obese mice. Consistently, adipocyte-specific PDGF-D overexpression transgenic mice (PA-Tg) showed exacerbated cardiac remodeling after AngII infusion without high-fat diet treatment. Mechanistic studies indicated that AngII-stimulated macrophages produce urokinase plasminogen activator (uPA) that activates PDGF-D by splicing full-length PDGF-D into the active PDGF-DD. Moreover, bone marrow-specific uPA knockdown decreased active PDGF-DD levels in the heart and improved cardiac remodeling in HFD hypertensive mice. Together, our data provide for the first time a new interaction pattern between macrophage and adipocyte: that macrophage-derived uPA activates adipocyte-secreted PDGF-D, which finally accelerates AngII-induced cardiac remodeling in obese mice.

Abstract
Objective: To compare the seroprevalence of hepatitis B in Guangzhou in 2008 and 2018. Methods: According to the proportion of Guangzhou population size, two-stage cluster sampling was used to select the residents aged 1-59 years in the two surveys. Results: 4 989 and 3 980 people aged 1-59 years were involved in 2008 and 2018, respectively. HBsAg prevalence was 9.50% (95%CI:7.34%-11.66%) in 2018 and 12.45% (95%CI:10.58%-14.33%) in 2008 among the people aged 1-59 years, with no significant difference statistically (χ2=18.302, P=0.075). The decrease of HBsAg prevalence was mainly in the population aged 7-16 years. For the people aged 7-16 years, the HBsAg prevalence was 0.88% (95%CI: 0.35%-1.42%) in 2018 and decreased by 80.62% as compared with the rate 4.54% (95%CI:2.71%-6.36%) in 2008, with statistically significant difference (χ2=34.144,P=0.000). Anti-HBs prevalence was 72.30% (95%CI:69.56%-75.04%) in 2018 and ascended by 11.35% as compared with the rate of 64.93% (95%CI:61.65 %-68.22%) in 2008 among the people aged 1-59 years, with statistically significant difference (χ2=51.618, P=0.001). The rise of anti-HBs prevalence was mainly in the population aged 17-59 years. For the people aged 17-59 years, the anti-HBs prevalence was 71.93% (95%CI: 68.90%-74.96%) and risen by 12.80% as compared with the rate of 63.77% (95%CI: 60.16%-67.37%) in 2008, with a statistically significant difference (χ2=28.422, P=0.001). HBV infection rate was 48.10% (95%CI: 43.20%-53.00%) in 2018 and decreased by 22.76% as compared with the rate of 62.27% (95%CI: 59.11%-65.44%) in 2008, with statistically significant difference (χ2=167.138, P=0.000). The HBV infection rates in the population aged 1-6 years, 7-16 years, and 17-59 years were 4.58%, 5.13%, and 56.56% (a decrease of 81.83%, 85.91%, and 18.47%), respectively. The infection rate of HBV was 48.87% (a decrease of 24.70%) in high epidemic areas and 28.81% (a decrease of 38.75%) in people with a history of hepatitis B immunization. Conclusion: The prevention and control of hepatitis B in Guangzhou have achieved remarkable results it already reached the national goal of reducing HBsAg prevalence to less than 1% among children under five years since 2008. However, the target goal of reducing the hepatitis B mortality rate is quite demanding. The neonatal hepatitis B vaccination and monitoring and screening in adults are still needed.

Abstract
Objective: To isolate the influenza A (H3N2) viruses from different sources in Guangzhou in 2019 and analyze these viruses' evolution and variation characteristics. Methods: The hemagglutinin (HA) and neuraminidase (NA) genes of H3N2 isolates from outpatient monitoring, influenza outbreaks, and inpatient severe cases in Guangzhou in 2019 were sequenced. Bioinformatics software analyzed the variations and evolution characteristics of HA and NA genes. Results: The epidemic peaks of influenza A (H3N2) viruses were made up of period Ⅰ (from January to August) and period Ⅱ (from November to December). The positive rate of influenza A (H3N2) in males was 13.46% (703/5 221), which was higher than that in females (11.50%, 510/4 435) (χ2=8.43,P=0.00). The group's positive rate of 10-20 years old was the highest (25.18%,665/2 641). The isolates from different sources were highly homologous and closely related to 3C.2a.1 branches, which could be further divided into three small groups of Group 1-3. Gene recombination was observed between different branches. The mutations of HA antigen sites gradually appeared from Group 1 to Group 3, leading to new antigen drift. Variations of HA antigenic sites mainly occurred in the region of A and B. The mutations of receptor binding sites of Group 1 and Group 3 viruses occurred in the anterior and posterior walls. There were two glycosylation sites lacked on region A of HA antigen observed in the isolates of Group 2-3. Conclusions: Genetic variations of H3N2 influenza viruses in Guangzhou included gene mutations and gene recombination. Under the pressure of the vaccine, the evolution of viruses was rapid. Therefore, the monitoring of molecular-related epidemic characteristics of the H3N2 influenza virus was necessary.

Abstract
Objective: Analyze epidemiological situation of dengue fever,and survey impacts of four serotypes dengue viruses in Guangzhou, 2019. Methods: Information of patients was collected in Notifiable Infectious Disease Report System (NIDRS). Spatial autocorrelation of dengue cases was evaluated using ArcGIS version 10.2. Serum samples were tested by real-time PCR. Virus strains were isolated from positive sera. Then E gene was sequenced. Phylogenetic trees were including PhyMLsoftwarev 3.1. Results: A total of 1 655 dengue cases, consisted of 1 382 local cases and 273 imported cases, was confirmed in 2019. The incidence was 11.10 per 100 000 dengue cases were autocorrelated in Guangzhou. There were 18 high-high clusters. Most of the imported dengue cases were imported from Southeast Asian countries (86.08%,235/273) and African countries (2.56%,7/273). Of 749 serum samples detected by real-time PCR, the positive rate was 93.06% (697/749). Four hundred and sixty-four dengue virus strains had been isolated in 2019. Compared with data from the genotype tree of the former years, no genotype shift was discovered. Serotype 1 was still predominant. Serotype 2 was the significant strain in Baiyun district and Liwan district. Conclusions: Dengue fever was spreading all over Guangzhou in 2019. The suburban areas, which played a more critical role in causing the spread and outbreak of dengue fever, should be given more prominence. Inspection at ports should be enforced to prevent importing cases from African countries and Southeast Asian countries. The risk of serotype 2 cannot be overlooked. Four serotypes dengue viruses prevailed simultaneously in Guangzhou, which warns us to take precaution of severe dengue outbreaks.

Abstract
Objective: To analyze the effects of hemocoagulase agkistrodon (HCA) on the coagulation status of healthy people and traumatic brain injury (TBI) patients in vitro. Methods: A total of 10 TBI patients were enrolled from December 2018 to June 2019,and 24 age and sex matched healthy controls were also enrolled. Clinical and pathological data, blood samples of all subjects were collected. Different gradient concentrations of HCA were added to the blood samples which were detected by thromboelastography, and the R value, K value, α angle and MA value of thromboelastography parameters between the two groups were analyzed to explore the effect of HCA on the coagulation status of patients with TBI. Results: With the increase of HCA concentration in blood samples, the R and K values gradually increased, and the α angles and MA values gradually decreased in both TBI patients group which included 7 males and 3 females, with an median age of 33 (28-39) years old and healthy control group which included 11 males and 13 females, with an median age of 33 (23-49) years old. The differences in the R values, K values, α angles, and MA values of different concentration gradients were statistically significant in both healthy control group and TBI patients group (χ2 were 109.80, 131.28, 185.47, 165.97 and 54.92, 75.60, 80.12, 59.25, respectively, all P<0.001). The differences between R values after adding HCA of 0-0.105 U/ml in the healthy group were statistically significant (P=0.025), but K values, α angles and MA values were not statistically significant (P values were 0.275, 0.206 and 0.330, respectively); the R values of the TBI patients group were not statistically significant after adding HCA of 0 to 0.105 U/ml (P=0.976), and the K values, α angles, and MA values were statistically significant (P values were 0.047, 0.041, and 0.034, respectively).The R values of the healthy control group, the TBI patients group, and the overall data were significantly positively correlated with the HCA dose (r values were 0.552、0.700、0.420, respectively, P<0.001), the K values were significantly positively correlated with the HCA dose (r values were 0.726、0.861、0.750, respectively, P<0.001), the α angles were significantly negatively correlated with the HCA dose (r values were -0.815、-0.876、-0.807, respectively, P<0.001) and the MA values were significantly negatively correlated with the HCA dose (r values were -0.757、-0.710、-0.729, respectively, P<0.001). Conclusions: HCA does not aggravate the procoagulant state of blood in healthy people and TBI patients, and with the increase of HCA concentration in blood, the blood samples of both groups show a tendency to decrease the coagulation ability.

Abstract
Objective: To analyze the contagiousness and secondary attack rate of 2019 novel coronavirus in cluster epidemics in Guangzhou and provide evidence for the prevention and control of COVID-19. Methods: All the individuals identified to be infected with 2019-nCoV in Guangzhou, including confirmed cases and asymptomatic cases, were included and classified as imported cases and local cases. The first case of each cluster epidemic was defined as index case, and the number of subsequent infections was calculated to evaluate the contagiousness and secondary attack rate of 2019 novel coronavirus in the shortest incubation period of 1-3 days. Results: As of 18 February, 2020, a total of 349 cases of 2019-nCoV infection, including 339 confirmed cases (97.13%) and 10 asymptomatic cases (2.87%) were reported in Guangzhou. There were 68 clusters involving 217 2019-nCoV infection cases (210 confirmed cases and 7 asymptomatic cases). The median number of subsequent infections caused by an index case in a cluster epidemic was 3, among which 2 were confirmed cases and 1 was asymptomatic cases, respectively. The average number of contagiousness was 2.18 in shorted incubation period of 1-3 days (The average number of infected cases were 2.18 cases by the index case in a cluster epidemic), the average infection number in family members was 1.86, and the infection ratio of family member transmission was 85.32% (1.86/2.18). The secondary attack rate in close contacts with shortest incubation period of 1-3 days was 17.12%-18.99%, the secondary attack rate in family members was 46.11%-49.56%. Conclusions: The cluster epidemic of COVID-19 in Guangzhou mainly occurred in families, the contagiousness was high. It is necessary to strengthen the prevention and control to reduce the community transmission of COVID-19.

Abstract
Objective: To compare epidemic characteristics between severe acute respiratory syndrome (SARS) and coronavirus disease 2019 (COVID-19). Methods: The general information, including epidemiological and clinical data of the confirmed cases during the epidemic period of the two infectious diseases was collected. The data of SARS in Guangzhou was derived from the technical files of Guangzhou Center for Disease Control and Prevention (GZCDC), including the statistical report and brief report of the epidemic situation (from January 2 to May 11, 2003);The data of COVID-19 in Wuhan was derived from the epidemic data published by Wuhan health and Health Committee's official website and other publicly reported documents (from December 9, 2019 to March 11, 2020). Descriptive analysis was used for a comparativeanalysis of the time and age characteristics, the number of cases, basic reproduction number (R0), proportion of medical staff in confirmed cases (%), crude mortality, etc. Results: A total of 1 072 cases of SARS in Guangzhou were included in the study. The incidence ratio of male to female was 1∶1.26. 43 cases of death were reported with a mortality rate of 4.01%. The median age was 36 years old. The proportion of medical staff in the early stage of the epidemic was 29.04% (88 cases). As to COVID-19 in Wuhan, a total of 49 978 cases were included, The incidence ratio of male to female was 1.04∶1. The 2 423 cases of death were reported with a mortality rate of 4.85%. The median age was 56 years old. The proportion of medical staff in the early stage of the epidemic was 30.43% (42 cases). Conclusion: The COVID-19 in Wuhan has the characteristics of high incidence and wide population. However, the epidemic situation is falling rapidly, and the prevention and control strategy needs to be adjusted timely. The prevention and control of nosocomial infection should be addressed in future.

Abstract
Objective: To investigate the epidemiological and clinical characteristics of a case infected with avian influenza A (H5N6) virus associated with exposure to aerosol and provide evidence for the prevention and control of human infection with avian influenza virus. Methods: Epidemiological investigation was conducted to identify the history of exposure, infection route, and disease progression. Real-time fluorescent quantitative RT-PCR was used to test the samples collected from the case, close contacts, environment and poultry market. Results: The case had no history of exposure to live poultry and poultry market. But before the onset the case had a history of exposure to the live poultry placed in a car with doors and windows closed. The samples collected from the case's lower respiratory tract and the remaining frozen chicken meat were all influenza A (H5N6) virus positive. Conclusions: The source of infection was the live poultry, and the infection route might be the exposure to aerosol in a car with doors and windows closed, where the poultry were temporarily stored. It is necessary to promote centralized poultry slaughtering, cold chain distribution and fresh poultry sale, as well as strengthen health education and establish the concept of consuming fresh poultry.

Abstract
Objective:By retrospectively analyzing the results of ultrasound guided coarse needle biopsy(CNB) of thyroid nodules based on large samples, so as to evaluate its diagnostic value as first-line diagnostic tool for thyroid nodules. Method:From October 2015 to November 2017, a total of 508 nodules were studied from 474 patients who underwent CNB in general surgery department of tianjin first central hospital. The nondiagnostic rate, inconclusive rate, unnecessary surgery rate and complication rate of thyroid nodules diagnosed by CNB were calculated. The accuracy, sensitivity, specificity, positive predictive value and negative predictive value of CNB in thyroid cancer diagnosis were analyzed. The correlation between inconclusive diagnostic results and ultrasonic findings like echogenicity, composition, margin, calcification type, blood supply and nodule size was analyzed. Result:The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of CNB diagnosis were 97.27%, 99.17%, 99.07%, 99.45% and 99.36%, respectively. However, the nondiagnostic rate, the inconclusive rate, the conclusive rate and the unnecessary surgery rate of thyroid nodules diagnosed by CNB were 2.95%, 7.09%, 92.92% and 1.86%, respectively. Conclusion:Ultrasound guided coarse needle biopsy might be safe and reliable for the diagnosis of thyroid nodules, with relatively stable diagnostic effect. It is not only of high diagnostic value but also can significantly reduce diagnostic surgery. Therefore, CNB could be the preferred examinational method for nodules with suspicious ultrasonic findings.

Abstract
Objective: To analyze the epidemiological characteristics, trend and related factors of tuberculosis patients that delayed for care, in Wuhan from 2008 to 2017. Methods: Data regarding tuberculosis (TB) patients was collected from the tuberculosis management information system (TMIS), a part of the China information system for disease control and prevention from 2008 to 2017. A total of 64 208 tuberculosis patients, aged 0 to 95 years were included for the analysis. Unconditional logistic regression method was used to estimate those factors that associated with this study. Results: Days of delay among TB patients appeared as M=10 (P(25)-P(75): 3-28) day, in Wuhan, 2008-2017. The prevalence of the delay was 52.5% (33 703/64 208), presenting a downward trend from 2008 to 2017 (trend χ(2)=10.64, P<0.001), but the proportions of women and ≥65 year-olds were gradually increasing. Results from the multivariate logistic regression analysis showed that factors as: patients living far away from the city vs. near the city (OR=1.29, 95%CI: 1.25-1.35), and age above 45 years vs. younger than 25 years (the age 45-64 years group vs. aged less than 25 years group, OR=1.22, 95%CI: 1.15-1.29; the age 65 or above group vs. aged less than 25 years group, the OR=1.30, 95%CI: 1.22-1.39) were under higher risk on the delay of seeking care. Occupation, way of case-finding and classification of tuberculosis patients also appeared as influencing factors on this issue. Conclusions: Prevalence on the delay of care was 52.5% among tuberculosis patients in Wuhan, 2008-2017, but with an annual decrease. Attention should be paid to female, wrinkly or elderly tuberculosis patients regarding the delay of care on TB, in Wuhan.

Abstract
The Jinling version of the Compendium of Materia Medica was the primary version.It accurately represented the ideas of LI Shizhen, therefore it was valued by the scholars.There were many defects in misprint (knife carving) and proofreading.The main errors were some Chinese character's strokes missing and wrong characters printed.The authors collected some statistics data andmade some statistical analysis. They found that total misprints were 376 and emerge 615 times.Those misprints can divide into two categories: lack of some parts of Chinese characters; lack of some strokes of Chinese characters.Four tables which list the misprints was made.It is helpful for scholars to examine Compendium of Materia Medica or the study of other similar ancient literatures.

Abstract
Objective: To investigate the incidence and proportion of salivary gland tumors in order to provide new thinking for clinical diagnosis and treatment. Methods: Collected 3 724 cases salivary gland tumors diagnosed by Pathology Department of Hospital of Stomatology, Jilin University from January 1961 to December 2016. The pathological diagnosis referred to the fourth edition of head and neck-salivary gland tumor histopathological classification standard of WHO. The database was established with Microsoft Excel and analyzed with SPSS 18.0. Made a retrospective analysis and comparison on the numbers of all cases in terms of types, site, gender and age and estimate the trend with the time interval of 8 years, and then make a judgement of the trend of salivary tumors. Results: The benign tumors were more common than the malignant among all periods, the proportion of all tumors was about 2.92∶1; The top three benign tumors were polymorphous adenoma [73.78% (2 046/2 773)], Warthin tumor [15.80% (438/2 773)] and base cell adenoma [8.37% (232/2 773)]. Polymorphous adenoma took up 54.94% (2 046/3 724) of all tumors. The top three malignant tumors were mucous epidermoid carcinoma [31.44% (299/951)], adenoid cystic carcinoma [26.92% (256/951)] and adenocarcinoma [11.88% (113/951)]. As for sex, male female ratio was 0.83∶1. As for site, the pathogenic site of tumors was mainly in parotid gland [63.75% (2 374/3 724)], followed by palatal gland [16.50% (615/3 724)], then submandibular gland [12.67% (472/3 724)]; As for age, the common age was between 51 and 60 years old [23.74% (884/3 724)], followed by 41 to 50 years old [21.56%(803/3 724)]. Conclusions: The incidence of benign and malignant salivary gland tumor increased in the 56 years. Females showed a higher incidence. The majority tumors occurred in parotid gland. The most common salivary gland tumor was pleomorphic adenoma and the most common malignant tumor was mucous epidermoid carcinoma. The most common age was in 51-60 years old period.

Abstract
Objective: To evaluate the high-risk histopathologic features of retinoblastoma eyes enucleated as primary treatment. Methods: Retrospective case series study. An analysis was carried out on the high-risk histopathologic features of 482 primarily enucleated retinoblastoma eyes in Beijing Tongren Eye Center during December 2011 and December 2016. The high-risk histopathologic features included post lamina cribrosa invasion, massive choroidal invasion, anterior segment invasion and extraocular invasion. According to the neovascularization of iris (NVI) in the tissue specimen, the patients were divided into the NVI positive group and negative group. The rates of high-risk histopathologic features in the NVI positive group and negative group were analyzed using the chi-square test. Results: Among 482 children with retinoblastoma, 280 (58.1%) were males and 202 (41.9%) were females. The median age at enucleation surgery was 24 months (range, 1-84 months). Of the 482 primarily enucleated eyes, 184 (38.2%) were classified as high-risk histopathologic features, including 148 (30.7%) with post lamina cribrosa invasion, 15 (3.1%) with optic nerve transection invasion, 66 (13.7%) with massive choroidal invasion, 35 (7.3%) with anterior segment invasion, and 5 (1.0%) with extraocular invasion. NVI was detected in 257 (53.3%) cases and there was a significant relation between high-risk histopathologic features and NVI. The rate of high-risk histopathologic features was significantly higher in the NVI positive group (123 cases, 47.9%) than the NVI negative group (61 cases, 27.1%) (χ(2)=21.883, P=0.001). The rate of post lamina cribrosa invasion was significantly higher in the NVI positive group (110 cases, 42.8%) than the NVI negative group (38 cases, 16.9%) (χ(2)=37.860, P=0.001). Conclusions: In this large sample of patients, about 1/3 of retinoblastoma eyes has high-risk histopathologic features. The NVI positive retinoblastoma is more likely to have high-risk histopathologic features or post lamina cribrosa invasion than the NVI negative retinoblastoma.

Abstract
Adipocytes play important roles in regulating cardiovascular health and disease. However, the molecular mechanism underlying the endocrine role of brown adipose tissue (BAT) in pathological cardiac remodeling remains unknown. Herein we show that adenosine A2A receptor (A2AR) knockout (A2ARKO) causes interscapular BAT (iBAT) dysfunction, leading to accelerated cardiac remodeling in hypertension compared with wild-type (WT) mice. Surgical iBAT depletion induces dramatic cardiac remodeling in WT but not in A2ARKO hypertensive mice. AMPK/PGC1α signaling-induced fibroblast growth factor 21 (FGF21) in brown adipocytes is required for A2AR-mediated inhibition of hypertensive cardiac remodeling. Recombinant FGF21 administration improves cardiac remodeling in iBAT-depleted hypertensive mice. More importantly, brown adipocyte-specific A2ARKO inhibits FGF21 production and accelerates cardiac damage in hypertension. Consistently, brown adipocyte-specific FGF21 knockout abolishes the effects of A2AR agonism in attenuating hypertensive cardiac remodeling. Our findings reveal a distinctive endocrine role of BAT in hypertensive cardiac remodeling via activating A2AR/FGF21 pathway.

Abstract
Obesity increases the risk of vascular diseases, including aortic aneurysm (AA). Perivascular adipose tissue (PVAT) surrounding arteries are altered during obesity. However, the underlying mechanism of adipose tissue, especially PVAT, in the pathogenesis of AA is still unclear. Here we showed that angiotensin II (AngII) infusion increases the incidence of AA in leptin-deficient obese mice (ob/ob) and high-fat diet-induced obese mice with adventitial inflammation. Furthermore, transcriptome analysis revealed that platelet-derived growth factor-D (PDGF-D) was highly expressed in the PVAT of ob/ob mice. Therefore, we hypothesized that PDGF-D mediates adventitial inflammation, which provides a direct link between PVAT dysfunction and AA formation in AngII-infused obese mice. We found that PDGF-D promotes the proliferation, migration, and inflammatory factors expression in cultured adventitial fibroblasts. In addition, the inhibition of PDGF-D function significantly reduced the incidence of AA in AngII-infused obese mice. More importantly, adipocyte-specific PDGF-D transgenic mice are more susceptible to AA formation after AngII infusion accompanied by exaggerated adventitial inflammatory and fibrotic responses. Collectively, our findings reveal a notable role of PDGF-D in the AA formation during obesity, and modulation of this cytokine might be an exploitable treatment strategy for the condition.

Abstract
Endothelial-to-mesenchymal transition (EndoMT) has recently emerged as a potentially important contributor in promoting fibrosis in chronic kidney disease. However, little is known about the role and molecular basis of its involvement in hypertensive renal injury. Here, we aim to determine the role of SIRT (sirtuin) 3 on EndoMT in hypertensive renal injury and to explore its underlying mechanisms. We found that SIRT3 expression was significantly reduced in Ang II (angiotensin II)-induced hypertensive model, accompanied with induction of EndoMT and increased reactive oxygen species and renal fibrosis. In SIRT3-/- (SIRT3 knockout) mice subjected to Ang II infusion, renal dysfunction was aggravated with an increased EndoMT and reactive oxygen species level, whereas in SIRT3-TgEC (SIRT3 endothelial cell-specific transgenic) mice, the Ang II-induced renal fibrosis and EndoMT and oxidative stress were ameliorated. With primary mouse glomerular endothelial cells, we confirmed that Ang II treatment initiated EndoMT and decreased catalase expression, which were suppressed by SIRT3 overexpression. Using immunoprecipitation, luciferase, and chromatin immunoprecipitation assay, we demonstrated that SIRT3-mediated deacetylation and nuclear localization of Foxo3a (forkhead box O3a) resulted in activated Foxo3a-dependent catalase expression. Moreover, Foxo3a knockdown abolished SIRT3-mediated suppression of EndoMT. In conclusion, these results established the SIRT3-Foxo3a-catalase pathway as a critical factor in the maintenance of endothelial homeostasis and point to an important role of EndoMT in the vascular pathology of renal fibrosis, which may provide a new therapeutic target to impede the progression of hypertensive renal injury.

Abstract
OBJECTIVE To form a new assessment method to evaluate postural workload comprehensively analyzing the dynamic and static postural workload for workers during their work process to analyze the reliability and validity, and to study the relation between workers' postural workload and work-related musculoskeletal disorders (WMSDs). METHODS In the study, 844 workers from electronic and railway vehicle manufacturing factories were selected as subjects investigated by using the China Musculoskeletal Questionnaire (CMQ) to form the postural workload comprehensive assessment method. The Cronbach's α, cluster analysis and factor analysis were used to assess the reliability and validity of the new assessment method. Non-conditional Logistic regression was used to analyze the relation between workers' postural workload and WMSDs. RESULTS Reliability of the assessment method for postural workload: internal consistency analysis results showed that Cronbach's α was 0.934 and the results of split-half reliability indicated that Spearman-Brown coefficient was 0.881 and the correlation coefficient between the first part and the second was 0.787. Validity of the assessment method for postural workload: the results of cluster analysis indicated that square Euclidean distance between dynamic and static postural workload assessment in the same part or work posture was the shortest. The results of factor analysis showed that 2 components were extracted and the cumulative percentage of variance achieved 65.604%. The postural workload score of the different occupational workers showed significant difference (P<0.05) by covariance analysis. The results of nonconditional Logistic regression indicated that alcohol intake (OR=2.141, 95%CI 1.337-3.428) and obesity (OR=3.408, 95%CI 1.629-7.130) were risk factors for WMSDs. The risk for WMSDs would rise as workers' postural workload rose (OR=1.035, 95%CI 1.022-1.048). There was significant different risk for WMSDs in the different groups of workers distinguished by work type, gender and age. Female workers exhibited a higher prevalence for WMSDs (OR=2.626, 95%CI 1.414-4.879) and workers between 30-40 years of age (OR=1.909, 95%CI 1.237-2.946) as compared with those under 30. CONCLUSION This method for comprehensively assessing postural workload is reliable and effective when used in assembling workers, and there is certain relation between the postural workload and WMSDs.

Abstract
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.

Abstract
Objective: To study the willingness and influence factors related to "centralized slaughtering, fresh poultry listing and marketing" strategy, among the household chefs, and provide reference for government to adjust and optimize the strategy on avian influenza prevention. Methods: According to the geographical characteristics and regional functions, 6 'monitoring stations' were selected from 12 residential districts of Guangzhou, respectively. Another 21 meat markets which selling live poultry, were selected in each station and 5 household chefs of each market were invited to attend a face to face interview. Basic information, personal cognitive, willingness and influencing factors to the policy were under study. Univariate and multivariate logistic regression methods were used. Results: A total of 664 household chefs underwent the survey and results showed that the rate of support to the "centralized slaughtering, fresh poultry listing and marketing" strategy was 44.6% (296/664). Results from the multi-factor logistic regression showed that those household chefs who were males (OR=1.618, 95% CI: 1.156-2.264, P=0.005), having received higher education (OR=1.814, 95% CI: 1.296-2.539, P=0.001), or believing that the existence of live poultry stalls was related to the transmission of avian influenza (OR=1.918, 95% CI: 1.341-2.743, P<0.001) were factors at higher risk. These household chefs also intended to avoid the use of live poultry stalls (OR=1.666, 95%CI: 1.203-2.309, P=0.002) and accept the "centralized slaughtering, fresh poultry listing and marketing" strategy. Conclusion: Detailed study on this subject and, setting up pilot project in some areas as well as prioritizing the education programs for household chefs seemed helpful to the implementation of the 'freezing-fresh poultry' policy.

Abstract
RATIONALE Inflammation and immunity play crucial roles in the development of hypertension. Complement activation-mediated innate immune response is involved in the regulation of hypertension and target-organ damage. However, whether complement-mediated T-cell functions could regulate blood pressure elevation in hypertension is still unclear. OBJECTIVE We aim to determine whether C3aR (complement component 3a receptor) and C5aR (complement component 5a receptor) could regulate blood pressure via modulating regulatory T cells (Tregs). METHODS AND RESULTS We showed that angiotensin II (Ang II)-induced hypertension resulted in an elevated expression of C3aR and C5aR in Foxp3 (forkhead box P3)+ Tregs. By using C3aR and C5aR DKO (double knockout) mice, we showed that C3aR and C5aR deficiency together strikingly decreased both systolic and diastolic blood pressure in response to Ang II compared with WT (wild type), single C3aR-deficient (C3aR-/-), or C5aR-deficient (C5aR-/-) mice. Flow cytometric analysis showed that Ang II-induced Treg reduction in the kidney and blood was also blocked in DKO mice. Histological analysis indicated that renal and vascular structure remodeling and damage after Ang II treatment were attenuated in DKO mice compared with WT mice. In vitro, Ang II was able to stimulate C3aR and C5aR expression in cultured CD4+CD25+ natural Tregs. CD3 and CD28 antibody stimuli downregulated Foxp3 expression in WT but not DKO Tregs. More important, depletion of Tregs with CD25 antibody abolished the protective effects against Ang II-induced hypertension and target-organ damage in DKO mice. Adoptive transfer of DKO Tregs showed much more profound protective effects against Ang II-induced hypertension than WT Treg transfer. Furthermore, we demonstrated that C5aR expression in Foxp3+ Tregs was higher in hypertensive patients compared with normotensive individuals. CONCLUSIONS C3aR and C5aR DKO-mediated Treg function prevents Ang II-induced hypertension and target-organ damage. Targeting C3aR and C5aR in Tregs specifically may be an alternative novel approach for hypertension treatment.

Abstract
Objective: To explore the status of seroepidemiology on hepatitis A, B and C among students and residents aged equal or greater than 18 years in south Xinjiang, and to provide scientific evidence for prevention and control of viral hepatitis. Methods: Uyghur students in four towns and villages were selected by cluster random sampling from Feb to May, 2015, and Uyghur residents aged 18 to 69 years were selected by stratified cluster sampling from May to September, 2016. 4 507 middle and primary Uygur students and 4 833 Uyghur resides equal or greater than 18 years attended this survey. Self-designed questionnaire was used to collect the demographic information. And Elisa test was adopted to detect HAV-IgG, HBsAg, HBsAb and HCV-IgG. Chi-square test was used to calculate the difference on antibody positive rate of three types of hepatitis among the participants. Results: The overall HAV-IgG positive rate was 99.45% (9 289/9 340). The positive rates were 99.70% (4 006/4 018) in male and 99.27% (5 283/5 322) in female (χ(2)=7.95, P=0.005). The HAV-IgG positive rate among people aged 10 to 14 years was the highest (99.91%, 2 233/2 235), and the difference between the age specific HAV-IgG positive rates was statistical significant (χ(2)=38.21, P<0.001). The overall HBsAg positive rate was 4.11% (384 cases), with 4.55% (183 cases) for male and 3.78% (201 cases) for female. The HBsAg positive rate among participants 19 to 24 years old was the highest (9.46%, 21/222) and the differences between the age specific HBsAg was statistically significant (χ(2)=116.22, P<0.001). The HBsAb positive rate was 35.03% (3 272 cases), with 35.59% (1 430 cases) for male and 34.61% (1 842 cases) for female, and the HBsAb positive rate among participants aged 15 to 18 years was the highest, which was 69.12% (696/1 007). The differences between the age specific HBsAb rates appeared statistically significant (χ(2)=671.80, P<0.001). The overall HCV-IgG positive rate was 0.65%(61 cases). The HCV-IgG positive rate in female was 0.86% (46 cases) and 0.37% (15 cases) in male (χ(2)=8.51, P=0.004).The HCV-IgG positive rate among participants aged over 70 years was the highest (3.78%,9/238) , and the difference between the age specific HCV-IgG positive rates had statistic significance (χ(2)=70.30, P<0.001). The HAV-IgG positive rate in hepatitis A vaccinees (100%, 876/876) was higher than that among the non-vaccinees (99.40%, 8 413/8 464) (χ(2)=4.26, P=0.039). The HBsAb positive rate in hepatitis B vaccinees was 39.32% (1 816/4 619) which was higher than that among the non-vaccinees (30.84%, 1 456/4 721) (χ(2)=73.68, P<0.001). Conclusion: The positive rate of overall HAV-IgG was high, male and participants aged between 10 to 14 had higher probability to be infected. But the infection rates of hepatitis B and C were low, with the low vaccination rate and the poor protective effectiveness of hepatitis B.

Abstract
Objective: To explore the phenotypic and genotypic characteristics in Chinese children with classic pantothenate kinase-associated neurodegeneration (PKAN). Method: The clinical, radiographic and genetic data of all PKAN patients diagnosed at pediatric department of Peking University First Hospital from November 2006 to December 2016 were retrospectively collected and analyzed. Result: Twenty patients with classic PKAN were included in the study. The median age at onset was 3.5 years (ranging from 1.0 to 10.0 years), and the most common initial symptom was gait disturbance (16 cases). At the last evaluation, the clinical features were limbs dystonia (20 cases), dysarthria (16 cases), dysphagia (11 cases), pyramidal sign (7 cases), mental regression (3 cases) and pigmentary retinopathy (5 cases). For those classic PKAN patients, the median time from onset of disease to loss of independent ambulation was 6.9 years (ranging from 2.0 to 12.0 years). Imaging data showed, except "eye of tiger" in MRI (19 cases), globus pallidus calcification in CT was also found in four patients. In gene testing, 26 different mutations in PANK2 gene were identified, and 16 of 26 were novel mutations. Moreover, c. 1502T>C (p.Ile501Asn) was the most common mutation (4 cases). Conclusion: Dystonia is the major neurologic feature of classic PKAN. Disease progression is rapid, with loss of independent ambulation within 10 years after onset. Except "eye of tiger" in MRI, globus pallidus calcification in CT may be another imaging feature of PKAN.Sixteen novel mutations of PANK2 gene were identified in the study.

Abstract
Objective: To identify the clinical and genetic characteristics in 43 Chinese children diagnosed with type Ⅰ Alexander disease (AxD). Method: Forty-three type Ⅰ AxD cases identified by glial fibrillary acidic protein (GFAP) gene mutations in Peking University First Hospital from 2005 to 2016 were followed up. The data of medical history, physical examination and magnetic resonance imaging (MRI) were collected. All these patients were followed up in December 2010, Febury 2012, June 2014 and January 2016, respectively. Result: Forty-three patients were genetically confirmed as type I AxD and the median age at the last visit was 11.71 years (10.27, 13.15). The characteristic clinical manifestations of these type Ⅰ AxD patients were developmental delay (79%, 34/43), seizures (86%, 37/43), macrocephaly (the median percentile of head circumference is 90%), and paroxysmal deterioration (27%, 13/43). All the 43 patients' brain MRI satisfied typical MRI features proposed by van der Knaap. According to the analysis of the long-term follow-up, patients with type Ⅰ AxD began to have obvious regression in motor function after 7 years of age, and the social life ability was milally impaired 8(6, 10)scores at the last follow-up. Seventeen heterozygous missense mutations of GFAP were identified in 43 genetically confirmed patients, and 4 mutations were novel. The mutations in 41 patients (95%, 41/43) were de novo. Three hot spots of mutation in Chinese patients were found: p. Arg239(35%, 15/34), p. Arg79 (26%, 11/43) and p. R88 (16%, 7/43). Conclusion: The characteristic clinical manifestations of type Ⅰ AxD patients are developmental delay, seizures, macrocephaly and paroxysmal deterioration. Moreover, a few patients may present with brain stem symptoms, mental abnormalities, scoliosis or kyphosis. Patients with type Ⅰ AxD may show significant regression in motor function after 7 years of age.

Abstract
Objective: To investigate the prevalence of hypertension and risk factors in Uygur adults in Kashgar of Xinjiang. Methods: A total of 4 748 Uygur adults aged ≥18 years selected through cluster random sampling in Shufu county of Kashgar prefecture were surveyed by means of questionnaire survey, physical examination and laboratory test. The prevalence, awareness, treatment and control rate of hypertension of different groups were calculated and risk factors of hypertension was analyzed by using non-conditional logistic regression model. Results: The overall prevalence of hypertension was 15.73% (age-adjusted prevalence was 13.75%). The prevalence rates of hypertension in men and women were 16.36% (age-adjusted prevalence was 12.96%), 15.39% (age-adjusted prevalence was 14.34%), respectively. The rates of awareness, treatment and control of hypertension were 59.57%, 52.74%, 21.29%, respectively. The prevalence of hypertension increased with age. Compared with age group 18-34 years, the age groups 55-64, ≥65 years had higher risk of hypertension and the OR values were 10.53, 20.96 for men and 16.27, 33.20 for women. The overweight (OR=1.47 for men, OR=1.82 for women, P<0.05) and obesity (OR=1.88 for men, OR=2.66 for women, P<0.05) also increased the risk of hypertension. The groups with family history of hypertension (OR=3.85 for men, OR=2.34 for women, P<0.05) also had higher risk of hypertension. Hypertriglyceridemia was positively correlated with the prevalence of hypertension in men (OR=1.62, 95%CI: 1.09-2.41). Conclusions: The prevalence of hypertension in Uygur adults in Kashgar area of Xinjiang was at relatively low level. The related risk factors were age, overweight, obesity, family history and hypertriglyceridemia in men and the risk factors were similar in women except hypertriglyceridemia.

Abstract
Objective: To investigate the knowledge, attitude and practice (KAP) to chronic diseases and associated influencing factors in Uygur adults in Kashgar of southern Xinjiang, and provide basic information for developing ethnic specific prevention and control strategies for chronic diseases. Methods: With stratified cluster random sampling, investigations, including questionnaire survey, physical examination and laboratory tests were performed among local residents who were aged ≥18 years and selected in Shufu county in southern Xinjiang. KAP scores were calculated and unconditional logistic regression models were used to analyze influencing factors. Results: A total of 4 772 Uygur adults were surveyed. The awareness rate of chronic disease related knowledge ranged from 4.32% to 56.04%, while the awareness rate of preventive measures were from 1.76% to 85.18% and the participation rate of prevention program varied from 4.00% to 97.99%. The average KAP score was 15.90±4.20 and the rate of total KAP was 47.86%. Multi-factor analysis suggested the pass rate of total KAP score increased with educational level. Other factors positively associated with 'KAP score pass rate' were commercial insurance investment, hypertension, family history of common chronic diseases, female and abdominal obesity, while overweight was negatively associated with the KAP score pass rate. Conclusions: The KAP level on chronic diseases was low in Uygur adults in Kashgar. It is necessary to continuously implement ethnic targeted health education and health promotion campaigns, especially in low education level, low income level, overweight and male groups.

Abstract
Objective: To investigate the epidemiologic characteristics of diabetes mellitus (DM) in Uygur residents in Kashgar of Xinjiang. Methods: The survey was conducted among the Uygur residents aged ≥18 years selected through stratified cluster sampling in Kashgar by means of questionnaire survey, physical examination and basic laboratory test. The prevalence of different groups were calculated and risk factors of DM was analyzed by logistic vegression model. Results: A total of 4 608 adults were surveyed. The prevalence of DM was 11.31% (standardized prevalence: 10.59%) and the prevalence was 13.65% (standardized prevalence: 12.34%) in males and 10.04% (standardized prevalence: 9.83%) in females. The prevalence increased with age. The prevalence of DM was higher than the prevalence of impaired fasting glucose (IFG) in people aged >60 years, especially in females. The rates of awareness, treatment and control of DM were 28.02%, 21.31% and 5.57%, respectively. Multivariate logistic regression analysis indicated that people aged 45-55, 55-65 and >65 years had higher risk of DM and the odds ratio were 2.08 (95%CI: 1.24-3.48), 2.73 (95%CI: 1.63-4.56) and 3.90 (95%CI: 2.24-6.78) for men and 2.63 (95% CI: 1.71-4.02), 3.14 (95%CI: 2.00-4.94) and 5.56 (95%CI: 3.47-8.92) for woman, respectively. Family history of DM (OR=2.88 for men, 95% CI: 1.45-5.72; OR=2.52 for women, 95% CI: 1.49-4.26) and BMI≥28.0 kg/m(2) (OR=1.77 for men, 95% CI: 1.19-2.64, OR=1.80 for women, 95% CI: 1.30-2.50) were also risk factors for DM. Conclusion: The prevalence of DM was high in Uygur residents in Kashgar, but the rate of awareness, treatment and control of DM were low. It is necessary to improve the detection rate of DM and conduct targeted prevention and control of DM.

Abstract
Objective: To explore the status of seroepidemiology on hepatitis A, B and C in primary and middle school students in Shufu county, Xinjiang Uygur Autonomous Region of China (Xinjiang) and to evaluate the effect of related immunization. Methods: Students in four towns and villages were selected by cluster random sampling method. HAV-IgG, HBsAg, HBsAb and HCV-IgG were detected in Feb to May, 2015. Results: The overall HAV-IgG positive rate was 99.75%, among 4 830 primary and middle school students. The positive rates were seen 99.92% in boys and 99.57% in girls, with difference statistically significant (χ2=5.798, P=0.016). The overall HBsAg positive rate appeared as 3.02%, with 3.55% for boys and 2.47% for girls, with difference statistically significant (χ2=4.782, P=0.029). The difference between age specific HBsAg positive rates also showed statistically significant (χ2=71.990,P=0.000). HBsAg positive rate in the students in rural area (3.28%) was higher than that in the students in urban area (1.61%, χ2=6.019, P=0.014). HBsAb positive rate was 38.84%, and the differences between the age specific HBsAb positive rates appeared statistically significant (χ2=837.699, P=0.000). HBsAg positive rate in students from the urban area (42.36%) was higher than those from the rural area (38.20%, χ2=4.598, P=0.032). 2 815 students, accounting for 58.28% of the total students, showed negative on both HBsAg and HBsAb. The overall HCV-IgG positive rate was 0.19%, and all appeared in students from the rural areas, with ethnicity solely as Uygur. Conclusions: The effect of hepatitis A vaccine was satisfactory in primary and middle school students in Shufu county but quiet a number of the students missed the vaccination. The infection rate of hepatitis C was low. Publicity and health education on hepatitis immunization and control should be revved up. Programs regarding primary and supplementary immunization on hepatitis, should be carried out timely for children of school age.
