Objective To investigate the epidemic situation and trend of brucellosis in Jinzhong City of Shanxi Province,and to provide a basis for formulating prevention and control measures.Methods Surveillance datas of human brucellosis in Jinzhong City from 2008 to 2012 were collected throng the national network straight quote system of infectious diseases and the centers for disease control and prevention of counties(districts,cities).Descriptive epidemiological method was used to analyze the distributions of region,time and population of brucellosis.Results A total of 3 627 cases were infected with brucellosis in Jinzhong City from 2008 to 2012,and the incidence of brucellosis was increased from 19.63 per 100 000 to 28.46 per 100 000.All counties(districts or cities) had reported epidemic from 2008 to 2012.The onset time focused on March-July each year,with obvious seasonal periodicity.The ratio of male to female was 5 ∶ 1.The ages were in 35-＜ 65 years old,accounting for 74.00％(2 684/3 627).Brucella infections were given priority to farmers and herdsmen,accounted for 93.63％ (3 396/3 627).Conclusions The epidemic of human brucellosis in Jinzhong City is in a spreading trend.Surveillance,timely analysis and report of the epidemic,health education,and inter-departments cooperation are in need to conduct in order to control the spread of epidemic.

Objective To explore the effects of cleaning staff's hygienic management intervention on the infection of staphylococcus aureus (SAU) in hospitalized patients. Methods Totals of 450 hospitalized patients from January to August 2016 in each department were selected. Starting from May 2016, the cleaning staff in charge of the departments were involved in the management of hand hygiene. The changes of hand hygiene awareness and infection control knowledge of the cleaning staff before and after the intervention were compared. Staphylococcus aureus infection was monitored in real time, and compared before and after the intervention. Results Before the intervention, the hygiene awareness of the cleaners was (39.81±3.28), and the hand hygiene rate was 60.15%. After the intervention, the hygiene awareness was (45.22±4.83), and the hand hygiene rate was 84.28%. The differences before and after intervention were statistically significant (t=2.219, χ2=4.463; P< 0.05). The average score of infection control knowledge before and after the intervention were (39.3±5.6) and (82.8±6.4) respectively, with a statistical difference (t=2.139, P=0.037). There were 112 cases of staphylococcus aureus infectoin in all departments before the intervention, and 71 cases after the intervention, with a statistical difference (χ2=2.983, P=0.027). Conclusions To strengthen the management of hand hygiene can effectively improve the hospitalization environment and reduce staphylococcus aureus infection.

Objective:To explore the status quo and influencing factors of caregivers' perception of nurses' empowerment behavior in children with type 1 diabetes mellitus (T1DM) , and to provide scientific basis for focusing on and efficiently empowering caregivers of children with T1DM.Methods:This study was a cross-sectional survey. A total of 360 children with T1DM who were admitted to 2 tertiary hospitals in Zhejiang Province from January 2019 to May 2020 were selected by the convenient sampling method. General information questionnaire, Patient Perceptions of Patient-Empowering Nurse Behaviors Scale (PPPNBS) and General Self-Efficacy Scale (GSES) were used to investigate and analyze the influencing factors. A total of 360 questionnaires were issued and 347 valid questionnaires were recovered, with an effective response rate of 96.4%.Results:The PPPNBS score of caregivers of 347 children with T1DM was (185.85±50.05) . Multiple linear regression analysis showed that the course of the disease, the age of the caregiver, the education background of caregivers and self-efficacy sense were influencing factors of perception of empowerment behavior of caregivers of children with T1DM ( P<0.05) . Conclusions:The perception of caregivers of T1DM children with nurses' empowerment behavior is at a moderate level. The course of the disease, age of caregivers, the education background of caregivers and self-efficacy are the influencing factors in perception of caregivers' empowerment behaviors of T1DM children. Medical staff should formulate targeted intervention measures based on the influencing factors of the perception of empowerment behaviors to improve the perception of nurses' empowerment behaviors by caregivers of patients.

Objective:To analyze the monitoring results of national brucellosis monitoring sites in Jinzhong City, Shanxi Province, and to provide a basis for scientific evaluation of prevention and control effects.Methods:From the "Disease Surveillance Information Report Management System", the surveillance results of national brucellosis surveillance sites (Pingyao County) in Jinzhong City from 2013 to 2021 were summarized and descriptive analysis was carried out.Results:From 2013 to 2021, a total of 996 cases of brucellosis were reported at the national brucellosis monitoring sites in Jinzhong City. A total of 3 538 serum samples were collected from key occupational groups, of which 161 were positive for brucellosis, with a positive rate of 4.55%. Among them, new cases accounted for 55.28% (89/161) and latent infections accounted for 21.74% (35/161). The annual serological test positive rate fluctuated between 1.19% and 20.55%. Except for 2014, the positive rate in all other years was less than 5.00%, and there was a statistically significant difference in positive rates between different years (χ 2 = 222.89, P < 0.001). The monitoring sites covered all townships within the jurisdiction (5 towns and 8 townships), and there was a statistically significant difference in positive rates among different townships (χ 2 = 26.45, P = 0.009). There was a statistically significant difference in positive rates among different occupations (χ 2 = 27.35, P < 0.001), with higher positive rates for veterinarians (5.41%, 2/37) and herders (4.76%, 29/609), respectively. There was a statistically significant difference in positive rates among different age groups (χ 2 = 42.97, P < 0.001), with a higher positive rate of 7.04% (104/1 477) in the 50 to 59 year old group. It can be seen from the scatter plot that the reported incidence rate did not increase linearly with the increase of serological positive rate. Conclusions:Except for 2014, the positive rate of serological tests for brucellosis at the national brucellosis monitoring sites in Jinzhong City, Shanxi Province has remained basically stable in other years. All townships in Pingyao County have an epidemic of brucellosis, and the 50 - 59 year old group and high-risk occupational groups are susceptible to it. The representatives of the monitoring results is not good, and it is recommended that the monitoring sites should strictly control the inclusion of the monitoring objects.
