Objective:To investigate the value of monitoring on serum silent information regulator-related enzyme 3 (SIRT3), glucagon-like peptide-1 (GLP-1) and angiopoietin-like protein 4 (ANGPTL4) in patients with acute ischemic stroke (AIS).Methods:Eighty patients with AIS who treatment in Qiongzhong Li and Miao Autonomous County People′s Hospital from May 2019 to April 2022 were selected retrospectively as the observation group, and 60 healthy volunteers who underwent physical examination during the same period were selected as the normal control group. The levels of serum SIRT3, GLP-1, and ANGPTL4 between the two groups were compared. The neurological deficit degree of AIS patients was evaluated by National Institutes of Health Stroke Scale(NIHSS) and the correlation of SIRT3, GLP-1 and ANGPTL4 with neurological deficit degree were analyzed. The levels of serum SIRT3, GLP-1 and ANGPTL4 before and after treatment and their difference value were compared between different clinical outcome of AIS patients, the risk factors for poor clinical outcome of AIS patients were analyzed by Logistic regression analysis, the value of prediction was analyzed by receiver operating characteristic (ROC) curve.Results:The level of serum GLP-1 in the observation group was lower than that in the normal control group: (50.37 ± 5.69) nmol/L vs. (34.89 ± 4.26) nmol/L; and the levels of serum SIRT3 and ANGPTL4 in the observation group were higher than those in the normal control group: (50.37 ± 5.69) ng/L vs. (34.89 ± 4.26) ng/L, (15.07 ± 3.12) μg/L vs. (11.15 ± 2.63) μg/L, there were statistical differences ( P<0.05). The results of correlation analysis showed that the levels of serum SIRT3 and ANGPTL4 were positively correlated with the degree of neurological impairment in AIS patients( r = 0.631, 0.776, P<0.05), and the level of serum GLP-1 was negatively correlated with the degree of neurological impairment in AIS patients ( r = - 0.693, P<0.05). After treatment, 66 patients obtained good clinical outcome, the good outcome rate was 82.50%(66/80). The levels of serum SIRT3 and ANGPTL4 in the poor clinical outcome patients were higher than those in the good clinical outcome patients: (41.33 ± 4.74) ng/L vs. (37.82 ± 4.05) ng/L, (12.98 ± 2.17) μg/L vs. (11.69 ± 2.06) μg/L; the level of serum GLP-1 in the poor clinical outcome patients was lower than that in the good clinical outcome patients: (592.33 ± 98.44) nmol/L vs. (709.41 ± 125.31) nmol/L; the difference value of SIRT3, GLP-1 and ANGPTL4 before and after treatment in the poor clinical outcome patients were lower than those in the good clinical outcome patients: (10.22 ± 2.05) ng/L vs. (12.31 ± 2.94) ng/L, (268.21 ± 70.12) nmol/L vs. (379.92 ± 85.33) nmol/L, (2.18 ± 0.65) μg/L vs. (3.36 ± 0.94) μg/L, there were statistical differences ( P<0.05). The results of Logistic regression analysis showed that differences value of SIRT3, GLP-1 and ANGPTL4 before and after treatment were all independent influencing factors of poor clinical outcome in patients with AIS ( P<0.05). The results of ROC curve analysis showed that the area under the curve (AUC) of differences value of SIRT3, GLP-1 and ANGPTL4 before and after treatment in predicting poor clinical outcome were 0.701, 0.758 and 0.844, respectively, and had certain predictive value, the AUC of joint evaluation was the largest (0.912). Conclusions:The levels of serum SIRT3 and ANGPTL4 in patients with AIS are increased, and the level of serum GLP-1 is decreased, and they are related to the degree of neurological deficit. Clinical monitoring of their level changes is helpful for clinical evaluation of the clinical outcome of patients with AIS.

Objective:To explore the medical costs and influencing factors of patients diagnosed with Brucellosis in Xinjiang Uygur Autonomous Region (Xinjiang).Methods:Information on demographics, medical visits, and costs of patients diagnosed with Brucellosis were collected between January 1,2017 and December 31,2019. The effects of different genders, age groups, clinical stages, and comorbidities on patients' health care utilization and medical costs were analyzed by nonparametric tests. The median was used to describe the outpatient and inpatient costs of patients with Brucellosis.Results:A total of 13 532 patients (8 113 outpatient and 5 419 inpatient cases) were included in the analysis. A total of 67.8% (9 176/13 532) were male, with an average age of (42.7±15.4 ) years; age between 18-44 years (46.6%, 6 304/13 532) and 45-59 years (34.2%,4 622/13 532) were the dominant groups. The mean age of inpatients [(43.3±15.7) years] was higher than that of outpatients [(42.3±15.1) years, Z=-3.85, P<0.001]. When hospitalized patients are treated,systemic symptoms were common with fever (36.9%, 1 997/5 419) and fatigue (36.6%, 1 983/5 419), and with joint/muscle pain (68.9%, 3 735/5 419) being the highest proportion of local symptoms. A total of 79.1% (4 289/5 419) of inpatients were diagnosed with acute Brucellosis. A total of 46.5% (2 519/5 419) of inpatients had complications;skeletal system complications ranked the highest. The average number of outpatient visits per outpatient was (1.6±1.4) times. The duration of hospitalization was (11.3±4.2) days, with longer days for patients in the chronic phase and with complications ( P<0.05). A total of 89.3% (4 840/5 419) of inpatients had outpatient records in the same year,and the average number of outpatient visits per patient was (3.6±2.6) times. Outpatient medical costs were dominated by laboratory and drug costs (75.1%), and inpatient costs were dominated by drug, laboratory, and other costs (74.4%). Outpatient medical expenses M( Q1, Q3) were 61(52, 497) Yuan, 61 (51, 346) Yuan and 58 (46, 318) Yuan,respectively. Inpatients' medical expenses M ( Q1, Q3) were 8 214 (6 355, 10 721) Yuan,9 095 (7 018, 12 155) Yuan and 9 492 (7 530, 12 351) Yuan, respectively. For patients, age, clinical stages,complications,and joint/muscle pain symptoms were influential factors for hospitalization costs ( P<0.001). Conclusions:The economic burden was higher for inpatients, especially those in the high age group, with chronic phases and skeletal and neurological complications. Improving patients' awareness of early treatment, standardized treatment, and reducing chronicity and complications are the main points in reducing the economic burden caused by Brucellosis diagnosis and treatment.

Objective:To understand the current status of personal protection in occupational population at high risk for brucellosis in China and provide evidence for the evaluation of implementation of National Brucellosis Prevention and Control Plan (2016-2020).Methods:Four counties in Shanxi Province and Xinjiang Uygur Autonomous Region were selected to conduct a questionnaire survey in occupational population at high risk for brucellosis from December 2019 to July 2020 by using cross-sectional survey methods.Results:A total of 2 384 persons at high risk for brucellosis were surveyed, and the standardized utilization rate of personal protective equipment (PPE) was 20.13% (480/2 384). The utilization rate of glove, mask, rubber shoe, and work cloth were 38.26% (912/2 384), 31.80% (758/2 384), 32.01% (763/2 384) and 30.87% (736/2 384),respectively. There were significant differences in the utilization rate and standardized utilization rate of the four types of PPE among populations in different age, occupation, educational level and area groups (all P<0.001). The utilization rate and standardized utilization rate of PPE were lower in people over 60 years old, women, farmers, and those with lower educational level. The results of multivariate analysis showed that occupation and area were the influencing factors for the standardized utilization of PPE, the standardized utilization rates of PPE were higher in herdsmen and veterinarians. The standardized utilization rate of PPE in Yanggao County and Huocheng County was significantly higher than that in Zuoyun County and Hunyuan County. Conclusions:The utilization rate of the four types of PPE in occupational population at high risk for brucellosis was not high in China, and the standardized utilization rate was low, lower than the requirement in National Brucellosis Prevention and Control Plan, and there were significant differences among different areas. It is urgent to distribute PPE to occupational population at high risk for brucellosis and carry out health education about PPE utilization. Meanwhile, it is necessary to strengthen information exchange or sharing among different areas.

Objective:To understand the current status of knowledge of brucellosis prevention and control among occupational groups at high-risk of brucellosis, and to provide a scientific basis for assessing the effectiveness of brucellosis prevention and control in China.Methods:A total of four counties in Shanxi Province and Xinjiang Uygur Autonomous Region were selected as survey counties from 2019 to 2020, and 600 people from the occupational groups at high-risk of brucellosis in each survey county were selected as survey respondents, and basic information and knowledge of prevention and treatment were collected through questionnaires. Single-factor and multi-factor logistic regression models were used to analyze the factors affecting the population's knowledge of prevention and treatment.Results:A total of 2 411 people participated in the survey and 2 384 valid questionnaires were obtained, including 1 405 males and 979 females, with the youngest age being 18 years old, the oldest being 91 years old, and the median being 57 years old. The overall knowledge of brucellosis prevention and control was 17.74% (423/2 384). The knowledge rate was lower among people over 60 years old, farmers, and people with less than elementary school education (13.99%, 14.50%, and 13.78%), and higher among women, herders, and people with elementary school education (20.02%, 36.33%, and 19.58%); the knowledge rate was lower in Hunyuan County (0.51%), and the differences in overall knowledge rates by age, occupation, education level, and region were statistically significant (χ 2 = 18.25, 87.18, 11.05, 197.43, P < 0.001). Multi-factor logistic regression analysis showed that gender, occupation, literacy and region were associated with knowledge of prevention and treatment ( P < 0.05). Conclusions:The overall knowledge of prevention and treatment among high-risk occupational groups in the key areas of China's brucellosis prevention and treatment program is low, with a large gap with the goals of the national brucellosis prevention and treatment program, and gender, occupation, literacy level, and region are the influencing factors of the knowledge of prevention and treatment. There is an urgent need to carry out a variety of health education activities for high-risk occupational groups and to strengthen the exchange of experience on brucellosis prevention and treatment between regions.
