RESUMO
@#Abstract: Objective To detect the antibody levels of hantavirus in serum samples from patients suspected with hemorrhagic fever with renal syndrome (HFRS) in Heilongjiang Province from 2019 to 2021, and to provide scientific basis for the prevention and control of disease. Methods Enzyme-linked immunosorbent assays (ELISA) were used to detect the IgM antibodies to hantavirus in serum samples collected from suspected patients with HFRS in the acute-phase, and IgM and IgG antibody in convalescent-phase serum samples. The positive rate of IgM antibody in acute-phase serum samples of patients in different years was analyzed with χ2 test by SPSS 19.0, and the data were sorted out and analyzed about patients' gender, occupation, age, date of onset and interval from onset to initial diagnosis by EpiData 3.1, Excel 2003 software. Results A total of 351 acute-phase serum samples and 208 convalescent-phase serum samples were detected in patients suspected with HFRS, respectively. There were 317 positive IgM antibodies of serum samples in the acute stage, with the positive rate of 90.31%. There was no significant difference in the positive rate of IgM antibodies in the acute stage between different years (χ2=0.895, P=0.639). T The IgM antibodies and IgG antibodies were positive in 32 (15.39%) and 28 (13.46%) of the convalescent-phase serum samples, respectively. Moreover, 148 patients (71.15%) were double-positive for IgM and IgG antibodies at the convalescent stage. The ratio of male to female patients was 4.56∶1, for which male patients were much more than female patients. Occupation was dominated by farmers (253 cases, 79.81%), followed by workers (19 cases, 5.99%) and the unemployed (17 cases, 5.36%), respectively. The age of patients ranged from 10 to 88 years old, with a median age of 49 years old. Most of the patients were in the age group from 30 years old to 60 years old (209 cases, 65.93%), among which the age group from 40 years old to 50 years old (86 cases, 27.13%) had the highest proportion, and the age group from 60 years old to 90 years old had a proportion of 20.18% (19 cases). May and November were the peak periods of HFRS in Heilongjiang Province. The median interval between onset and initial diagnosis was 4 days. Conclusions There is a gap of about 10% between the clinical diagnosis of HFRS cases and the confirmed cases detected by laboratory in Heilongjiang Province from 2019 to 2021. The virus-specific detection results are important for confirming the diagnosis of local patients with HFRS.
RESUMO
Objective To predict the potential suitable habitat of Haemaphysalis concinna in Heilongjiang Province under different climatic scenarios. Methods The geographic locations of ticks in Heilongjiang Province from 1980 to 2022 were captured from literature review and field ticks monitoring data from Harbin Center for Disease Control and Prevention in Heilongjiang Province, and the tick distribution sites with spatial correlations were removed using the software ArcGIS 10.2. The environment data under historical climatic scenarios from 1970 to 2000 and the climatic shared socioeconomic pathways (SSP) 126 scenario model from 2021 to 2040 and from 2041 to 2060 were downloaded from the WorldClim website, and the elevation (1 km, 2010), population (1 km grid population dataset of China, 2010) and annual vegetation index (1 km, 2010) data were downloaded from the Resource and Environmental Science and Data Center, Institute of Geographical Sciences and Natural Resources, Chinese Academy of Sciences. The contribution of environmental factors to H. concinna distribution was evaluated and environmental variables were screened using the software MaxEnt 3.4.1 and R package 4.1.0, and the areas of suitable habitats of H. concinna and changes in center of gravity were analyzed using the maximum entropy model in Heilongjiang Province under different climatic scenarios. In addition, the accuracy of the maximum entropy model for prediction of H. concinna distribution was assessed using the area under curve (AUC) of the receiver operating characteristic curve. Results A total of 79 H. concinna distribution sites and 24 environmental variables were collected, and 70 H. concinna distribution sites and 9 environmental factors that contributed to distribution of the potential suitable habitats of H. concinna in Heilongjiang Province were screened. The three most significant contributing factors included precipitation seasonality, annual precipitation, and mean temperature of the driest quarter, with cumulative contributions of 60.7%. The total area of suitable habitats of H. concinna was 29.05 × 104 km2 in Heilongjiang Province under historical climatic scenarios, with the center of gravity of suitable habitats located at (47.31° N, 129.16° E), while the total area of suitable habitats of H. concinna reduced by 0.97 × 104 km2 in Heilongjiang Province under the climatic SSP126 scenario from 2041 to 2060, with the center of gravity shifting to (47.70° N, 129.28° E). Conclusions The distribution of suitable habitats of H. concinna strongly correlates with temperature and humidity in Heilongjiang Province. The total area of potential suitable habitats of H. concinna may appear a tendency towards a decline with climatic changes in Heilongjiang Province, and high-, medium- and low-suitable habitats may shift.
RESUMO
Objective To analyze the incidence, mortality and time trend of lung cancer in Heilongjiang Cancer Registries from 2013 to 2017. Methods We calculated the incidence (mortality) rate and age-standardized incidence (mortality) rate of lung cancer in Heilongjiang Cancer Registries from 2013 to 2017. Chinese population census in 2000 and World Segi's standard population were used for age-standardization. Annual percentage change (APC) was calculated using Joinpoint software. Results The incidence of lung cancer in Heilongjiang Cancer Registries from 2013 to 2017 was 63.44/105 and ASR China was 36.14/105. The incidence of lung cancer in males (78.08/105) was higher than that in females (49.04/105). The incidence of lung cancer in rural areas (65.54/105) was higher than that in urban areas (58.20/105). From 2013 to 2017, the mortality rate of lung cancer in Heilongjiang Cancer Registries was 57.02/105, and ASR China was 32.53/105. The mortality rate of lung cancer in males (69.92/105) was higher than that in females (44.40/105). The mortality rate of lung cancer in rural areas (60.68/105) was higher than that in urban areas (48.02/105). The incidence of lung cancer in the 55-year-old age group showed a downward trend (APC=-5.0%, t=-5.1, P < 0.05), and the mortality rate of lung cancer in the 70-year-old group showed a downward trend (APC=-4.9%, t=-5.0). Conclusion Heilongjiang Province is a high incidence area of lung cancer.

RESUMO
Objective To assess the epidemiological characteristics of hypertension and its attributing factors in Heilongjiang province and establish a comprehensive basis for the prevention and control of hypertension in this region. Methods Using the stratified chunk method, a survey lasting 50 years was conducted on a sample of 299 677 (including i 58 782 males and 140 895 females) patients, aged 15 and above, residing in both rural and urban areas of Heilongjiang province from 1958 to 2007. Both blood pressure measurement and analysis on attributing factors of hypertension were carried out in 1958, 1979, 1991, 1999 and 2007. Results The prevalence of hypertension was significantly higher in Heilongjiang than in other provinces. It elevated annually, reaching a 3-fold increase in 50 years with an accelerating pace ( 17.06% to 25. 69% ) in the recent 8 years. Among the people examined, the prevalence of hypertension increased with aging. Furthermore, the prevalence of hypertension varied among different professions. Office workers had the highest prevalence (41.67%). Compared with female population, male participants had a much higher prevalence before the age of 55 (P < 0.0001 ). Body mass index, gender, hypertriglyceridemia, age, low-high density lipoprotein cholesterol and family history were identified as major risk factors for the development of hypertension in Heilongjiang province. However, the awareness (48. 90% ), treatment (25.33%) and control (4. 32% ) rates of hypertension in this region were relatively low. Conclusion The results of the present study identified Heilongjiang province as a high-risk region for hypertension. It also suggests the necessity to plan and implement actions for the effective prevention and treatment of hypertension in this region.
