Objective To explore gene polymorphism of the C/T genotype of rs1143627 in the promoter of IL-1β gene in male population living in the coastal area of Shandong, and thus to investigate the relationship between the gene polymorphism of IL-1β and gout. Methods A total of 208 gout patients and 210 healthy controls were enrolled. The possible association between the polymorphism of IL-1 β -3 1C/T and gout in Chinese were investigated and genotype frequencies and allelic frequencies was calculated by polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP) method. Hardy-Weinberg was used to verify the representativeness of the sample. Comparisons between the groups were performed with χ2 test and t-test. Results The frequencies of CC, CT, and TT genotypes were 32.7%, 43.3% and 24.0%,respectively among gout patients, while they were 31.9%,46.2% and 21.9%, respectively among the controls.There was no statistically difference in IL-1β -31C/T genotype frequencies between gout patients and controls (χ2=0.427, P>0.05). The allele frequencies of C and T in gout cases were different from those in the controls (54.3%, 55.0%; 45.7%, 45.0%; χ2=0.038, P>0.05). Moreover, no association between IL- I β-31 C/T genotypes and risk factors for gout were observed in gout cases by χ2 test. Conclusion Results of the present study suggest that the C/T genotype of rs1143627 in the promoter of IL-1β gene is not associated with gout in male population living in the coastal area of Shandong.

Objective:To analyze the epidemiological, clinical characteristics and treatment of coronavirus disease 2019 (COVID-19) in Northeastern Sichuan, and summarize experience in time to provide reference for clinical diagnosis and treatment.Methods:A retrospective study was conducted. Fifty-nine patients with COVID-19 admitted to Bazhong Central Hospital and Dazhou Central Hospital from January 27th to February 9th, 2020 were selected as the subjects. The data of demography, epidemiology, laboratory examination, chest CT and related clinical treatment were collected. According to the severity of the disease, the patients were divided into three types: mild, general and severe types, and the differences of the above indices among different clinical types were compared.Results:① General information and epidemiology: 31 cases (52.5%) were male, 28 cases (47.5%) were female, the average age was (42.0±16.4) years old, and the patients over 40 years old accounted for the largest proportion (35 cases, 59.3%). The proportion of clinical type was 72.9% (43 cases) in general type, and 62.7% (37 cases) were imported type. With the increase of disease severity, the average age of patients also showed a significant increase trend [the age of the mild, general and severe patients were (30.9±13.6), (42.7±15.3), (55.8±18.9) years old, P < 0.01]. The proportion of patients with more than one basic disease in severe patients was significantly higher than those in mild and general patients [66.7% (4/6) vs. 20.0% (2/10), 9.3% (4/43), both P < 0.05]. In the distribution of clinical symptoms, the proportion of severe patients with chest distress/dyspnea was significantly higher than those in mild and general patients [66.7% (4/6) vs. 10.0% (1/10), 11.6% (5/43), both P < 0.05]. ② Laboratory examination index: the total number of white blood cell count (WBC), neutrophils count (NEU), C-reactive protein (CRP) in severe patients were higher than those in mild patients and general patients [WBC (×10 9/L): 7.21±4.35 vs. 5.85±1.69, 5.43±2.04; NEU (×10 9/L): 6.09±4.43 vs. 3.95±1.45, 3.54±1.83; CRP (mg/L): 16.00 (8.20, 46.43) vs. 5.00 (0.00, 16.13), 15.00 (3.13, 28.58)], the albumin (Alb) level in severe patients was lower than those in mild and general patients (g/L: 38.00±5.35 vs. 49.23±5.27, 39.81±2.15, both P < 0.05), while the hemoglobin (Hb) level in mild patients was higher than that in severe and general patients (g/L:155.2±12.1 vs. 141.3±6.8, 131.1±11.7, both P < 0.05). ③ Chest imaging: the CT manifestations of typical cases were single or multiple ground glass shadows. With the progress of the disease, the focus gradually increased, the scope gradually expanded, and multiple solid shadows of lung lobes were involved. ④ Treatment: all patients received at least 2 kinds of antiviral therapy, and the application rate of Interferon and Ribavirin in severe patients were higher than those in mild and general patients [100.0% (6/6) vs. 80.0% (8/10), 97.7% (42/43); 83.3% (5/6) vs. 0% (0/10), 20.9% (9/43); all P < 0.05]. ⑤ Prognosis: until March 6th 2020, 50 patients (84.8%) were discharged from the hospital after rehabilitation, and the remaining 9 patients were still under treatment, none deaths. Conclusions:The proportion of severe patients with chest distress/dyspnea is higher, the older the patients are and the more basic diseases are, the more likely they are to develop into severe type. High resolution chest CT could be considered for suspected cases or even fever patients, which may show the progress of the disease.

Since its founding 100 years ago, the Communist Party of China (CPC) has attached great importance to the occupational health of workers, and closely linked the safeguard of occupational safety and health of workers with the missions of leading the people to stand up, get rich, and become strong. Based on this, the achievements of occupational health work made under the leadership of the CPC since the new democratic revolution, socialist revolution and construction, the new period of reform and opening up and socialist modernization, and socialism with Chinese characteristics for a new era were summarized, so as to provide reference for understanding the legacy of China's occupational health undertaking, and innovating to create the future.
