RESUMO
Background Air pollution has gradually become a major environmental and public health problem faced by countries around the world. Hazy weather not only affects the health of the population, but also poses a threat to social and public safety. China has successively promulgated policies such as the "Ten Articles on Atmosphere" and the Three-year action plan to fight air pollution, aiming to improve ambient air quality. It is clear that the Beijing-Tianjin-Hebei region has accomplished the set targets and improved air quality according to the environmental monitoring data of 2017. Objective To assess air quality improvements through the evaluation of the disease burden due to fine particulate matter (PM2.5) pollution in Shijiazhuang City before and after the air quality improvement from 2014 to 2021, including fatalities and health economic losses attributed to PM2.5 pollution. Methods Data on causes of death, PM2.5 concentrations, the number of permanent residents at the end of the year, gross regional product, and disposable income per capita in urban areas of Shijiazhuang were collected from 2014 to 2021. Total, non-accidental, circulatory, and respiratory deaths due to PM2.5 pollution were estimated by global exposure mortality models (GEMM). Health and economic losses due to selected diseases were calculated by value of statistical life (VOSL). Results During the study period, the average annual concentration of PM2.5 in Shijiazhuang was highest in 2014, and began to decline year by year in 2017, but all exceeded the current national limit of the second level of ambient air quality standards (35 μg·m−3). The total deaths, non-accidental deaths, circulatory disease deaths, and respiratory disease deaths attributed to PM2.5 pollution from 2014 to 2021 were 41326, 40246, 21792, and 5022, respectively; the associated health economic losses were 37.362, 36.369, 19.695, and 4.535 billion yuan, respectively. From the perspective of improved air quality, both the number of attributed deaths and health economic losses had declined in a volatile manner since 2017, with a significant decrease in 2019. If the average annual concentration of PM2.5 reached the second-level limit of China's ambient air quality standard (35 μg·m−3), the total deaths, non-accidental deaths, and deaths from circulatory diseases and respiratory diseases due to PM2.5 pollution would deducted by about 17000, 16000, 9000, and 2000, respectively; the corresponding health and economic losses would decreased by 15.201, 14.761, 7.959, and 1.859 billion yuan, respectively. If the average annual concentration of PM2.5 reached the latest PM2.5 air quality guidelines (5 μg·m−3) proposed by the World Health Organization, the total deaths, non-accidental deaths, circulatory disease deaths, and respiratory disease deaths due to PM2.5 pollution would deducted by 36000, 35000, 19000, and 4000, respectively, and the corresponding health and economic losses would reduced by 32.673, 31.796, 17.211, and 3.969 billion yuan, respectively. Conclusion PM2.5 pollution can lead to severe mortality burden and economic loss. Under the implementation of the State Council's "Ten Articles on Atmosphere" and the Three-year action plan to fight air pollution, Shijiazhuang's PM2.5 concentration and health economic losses have been significantly reduced, and further control of PM2.5 pollution can achieve greater health benefits and economic gains, affirming the positive results of local air pollution prevention work.
RESUMO
Objective To investigate the application of radiological diagnosis and treatment equipment and distribution of medical radiation levels in medical institutions at various levels in Shijiazhuang, China in 2019, and to lay a sound foundation for further radiation protection and management. Methods A universally designed questionnaire was used to investigate and compile data on the level of the sampled hospitals, the number of radiation workers, equipment information, the number of outpatients and emergency patients, the number of inpatients, and the frequency of radiological diagnosis and treatment; the application frequency of each radiological diagnosis and treatment item was calculated based on the demographic data of Shijiazhuang. Results In Shijiazhuang, there were 390 medical institutions (excluding dental clinics) certified for radiological diagnosis and treatment, with a total of 4262 radiation workers and 1215 radiological diagnosis and treatment devices; 1.11 radiological diagnosis and treatment devices were available per 10 000 people, and 3.89 radiation workers were available per 10 000 people. The number of annual outpatients and emergency patients was 30 208 471, the number of inpatients was 1 981 295, and the total number of people or times receiving radiological diagnosis and treatment was 5 987 230. The application frequency of medical radiation was 546.70 persons/times per 1000 people, with the highest frequency for X-ray diagnosis (534.63 persons/times per 1000 people), followed by diagnosis and treatment with nuclear medicine (6.16 persons/times per 1000 people), and the lowest frequency for radiotherapy (1.17 persons/times per 1000 people). In terms of regional distribution, the highest frequency of medical radiation fell in Yuhua District (1602.97 persons/times per 1000 people), and the lowest frequency fell in Shenze County (203.21 persons/times per 1000 people). Conclusion The development of medical radiation is imbalanced in Shijiazhuang, with high-quality medical resources concentrated mainly in the main urban area, thus resulting in long-term overworking of hospital staff and equipment in some areas. The government and health administration departments should strengthen macro-control and the rational allocation of medical resources; medical institutions at various levels should rationally use radiological diagnosis and treatment equipment, strengthen judgments on the justness of radiation, and strengthen the training of radiation workers on protection knowledge and radiation protection optimization.
RESUMO
Objective:To analyze the rules of medication and principles of formulas for the treatment of coronavirus disease 2019 (COVID-19) using the traditional Chinese medicine inheritance support platform (V2.5).Methods:The clinical data, including gender, age, clinical symptoms, frequency of traditional Chinese medicine medication and prescription information, of patients with COVID-19 and asymptomatic infection who were admitted to Hebei COVID-19 designated hospital supported by medical team of First Affiliated Hospital of Hebei University of Chinese Medicine from January to March 2021 were collected. The information data were input into the traditional Chinese medicine inheritance support platform (V2.5). The data mining and analysis were realized by the integrated association rules and complex entropy clustering analysis methods of the software, including the analysis of the frequency of each drug use, drug meridian, taste, and prescription rules, and the new prescriptions were developed.Results:A total of 564 patients (564 prescriptions) were enrolled, involving 200 Chinese herbs, including 357 cases of common COVID-19 and 207 cases of asymptomatic infection. The proportion of women with common COVID-19 was high, and the high incidence age group was 51-70 years old. There was no significant difference in gender of asymptomatic infection, and the high incidence age group was 1-20 years old. The main clinical manifestations of most patients were head heavy and cough, followed by low fever and cough with sputum, the main tongue coating and pulse pattern were similar in both types of patients. The frequency of traditional Chinese medicine used in patients with common type of COVID-19 from high to low was liquorice root (326 times), indian bread (264 times), pinellia tuber (263 times), bitter apricot seed (236 times), baical skullcap root (229 times), gypsum (205 times), agastache rugosus (201 times), dried tangerine peel (194 times), ephedra (184 times), and Chinese thorowax root (163 times), while that used by asymptomatic infection were baical skullcap root (174 times), liquorice root (142 times), medicated leaven (137 times), agastache rugosus (127 times), pinellia tuber (114 times), Chinese thorowax root (100 times), officinal magnolia bark (91 times), atractylodes rhizome (89 times), peony root (84 times), and milkvetch root (83 times). The two types of patients were mainly treated with warm, cold and flat drugs, and the nature and taste were mainly pungent, bitter and sweet. The meridian tropism of drugs was mainly lung, spleen and stomach. High frequency drug formulation mainly included drugs for resolving turbidity and detoxification. At the same time, seven new prescriptions for common COVID-19 and four new prescriptions for asymptomatic infection were developed.Conclusions:The primary reason for the COVID-19 occurrence and development is turbidity-toxin and the qi of plague, and resolving turbidity and detoxication are the basic treating principle. On the basis, for patients with common COVID-19, symptomatic treatment such as relieving exterior syndrome, clearing heat, resolving phlegm, and antitussive drugs should be taken into account at the same time, while the treatment of asymptomatic infections should focus more on supporting the body and eliminating the harmful pathogens.
RESUMO
Objective:To model an outbreak of coronavirus disease 2019 （COVID-19） in Shijiazhuang and forecast its spread trend. Method:We collected confirmed COVID-19 cases from the Health Commission of Hebei Province during the period of January 2 to January 27， 2021. We built a new model （SEIaIcRK）， including the contribution of asymptomatic cases， based on the traditional SEIR model to explore and analyze the transmission of COVID-19. Results:A total of 863 confirmed cases were reported during the study period （ended on January 27， 2021）. Our model fitted well with the daily cumulative incidence data and showed that the effective reproductive number decreased sharply from 3.80 on January 2 to 1.54 on January 4， then further decreased to <1 afterwards. Our model also predicted that number of COVID-19 cases would not increase after Feb 16， 2021. Conclusion:The SEIaIcRK model can be used to predict the spread trend of COVID-19 in Shijiazhuang. The current COVID-19 countermeasures effectively contain the disease spread.
RESUMO
Objective To analyze the overseas imported malaria situation of Shijiazhuang City from 2012 to 2015,so as to provide the evidence for exploring the prevention and control strategy. Methods The data of overseas imported malaria were collected and analyzed with the descriptive method including Plasmodium species,population characteristics,epidemic focus distribution,onset time,diagnosis and treatment in Shijiazhuang City from 2012 to 2015,and the time from the onset to first medical visit,time from first medical visit to being diagnosed,and time from onset to being diagnosed of different Plasmodium species were analyzed respectively with the statistical analysis method. Results A total of 92 overseas imported malaria cases were reported in Shijiazhuang City from 2012 to 2015,including 88 cases from African countries(falciparum malaria taking 53.41％),and 4 cases from Southeast Asian and other countries(vivax malaria taking 50％). Eighty-nine cases were distributed in 28 counties(districts)of 6 cities in Hebei Province,except 2 persons with foreign nationalities and 1 with Anhui Province cen-sus register. The male and young adults were dominant. The median time from the onset to seeing a doctor was one day and the median time from seeing a doctor to being diagnosed was five days. Most cases were reported by the Fifth Hospital of Shijia-zhuang which was the sentinel hospital. Totally 42.39％of the cases were misdiagnosed when the first visit to a doctor. All of the cases were laboratory confirmed and 100％of them received the standard treatment after diagnosis. Conclusions The overseas imported malaria cases are increasing rapidly with years and the malignant malaria cases were more than other malaria cases in Shijiazhuang City. It is necessary to further strengthen the long-term cooperation mechanism between the medical institutions and the entry-exit inspection and quarantine department. The technician training should be strengthened to avoid the severe cas-es and death cases.
RESUMO
Objective:To study the incidence rates of cancer in the urban area of Shijiazhuang city, China in 2012 based on the data of 2,374,827 registered residents. Methods: The incidence of diagnosed cancer cases in 2012 was obtained from the hospital reimbursement database of the medical insurance center of the city by retrieving the records on first-time reimbursement applications for the hospitalization of tumor patients from January 1 to December 31 in 2012. Population census data was obtained from the Population Department of the Shijiazhuang Public Security Bureau. The site-specific and sex-specific age-adjusted incidence rates were calculated. Results:The overall incidence rate, the age-adjusted rate of the Chinese population (ASRC), and the age-adjusted rate of the world population (ASRW) for both men and women were 237.53, 129.86, and 167.71 per 100,000 individuals, respectively. The incidence rate increased with age and peaked in the 75-79 years age groups of men and women at 1,729.42 and 867.35 per 100,000 individuals, respectively. The top ten most frequently diagnosed cancers in males were lung, stomach, colorectal, liver, esophagus, kidney, prostate, leukemia, bladder, as well as lymphoma, whereas those in females were the breast, lung, colorectal, stomach, cervical, uterine body, ovary, lymphoma, esophageal, and liver cancers. The incidence rate and ASRW of all cancers combined in men were 269.05 and 187.52 per 100,000 individuals, whereas those for women were 207.57 and 150.44 per 100 000 individuals, respectively. Compared with the average incidence rates of 31 Chinese cities in 2009, the ASRW of lung, stomach, and colorectal cancers in males from Shijiazhuang was nearly equal to the national level;however, the ASRW of breast cancer in females from Shijiazhuang was higher than the national level. When the incidence rates of Shijiazhuang in 2012 were compared with those of Beijing in 2009, the ASRW of stomach and esophageal cancers in men of Shijiazhuang was twice that of the same cancers in Beijing. However, the same parameters for the pancreatic and prostate cancers in men, as well as the thyroid and uterine body cancers in women of Beijing, were twice the values for Shijiazhuang. Conclusion: The ASRWs of the major types of cancer, such as the lung, stomach, colorectal, and breast cancers, in urban Shijiazhuang in 2012 were identical to those of the 31 Chinese cities in 2009. Compared with Beijing, the incidence rates of pancreatic, prostate, and thyroid cancers were significantly higher in Shijiazhuang, whereas those of esophageal and stomach cancers were significantly lower.
