ABSTRACT
Objective:To understand the contents of edible salt iodine and urinary iodine of children and pregnant women in Yunnan Province, and to evaluate the iodine nutrition status, so as to provide a basis for scientific prevention and treatment of iodine deficiency disorders (IDD).Methods:From November to December 2020, one county (city) was selected from each prefecture (city), two townships (towns and streets) were selected from each county (city) and two villages (neighborhood committees) were selected from each township (town and street) from each of the 16 prefectures (cities) in Yunnan Province as the investigation sites. A total of 20 non-boarding children (male and female balanced) aged 8 - 10 years old were selected from each primary school in each village (neighborhood committee) to collect salt and urine samples. A total of 80 children were investigated in each county (city). A total of 20 pregnant women were selected from each township (town and street) to collect salt and urine samples. A total of 40 pregnant women were investigated in each county (city). All salt samples and urine samples were tested for iodine contents.Results:A total of 2 009 salt samples and 2 041 urine samples (1 375 for children, 666 for pregnant women) were collected from children aged 8 - 10 years old and pregnant women in 16 counties (cities) of Yunnan Province. Among them, the median salt iodine was 26.0 mg/kg, the coverage rate of iodized salt was 100.0% (2 009/2 009), the qualified rate of iodized salt was 98.7% (1 982/2 009), and the consumption rate of qualified iodized salt was 98.7% (1 982/2 009). The difference of salt iodine content in key populations in different counties (cities) was statistically significant ( H = 258.98, P < 0.01). The median urinary iodine of children aged 8 - 10 years old was 188.5 μg/L. There was statistically significant difference in urinary iodine content among children of different ages ( H = 29.45, P < 0.01), but there was no statistically significant difference in urinary iodine content among children of different genders ( H = 1.43, P > 0.05). In addition, the median urinary iodine of pregnant women was 141.9 μg/L, 52.1% (347/666) was < 150 μg/L. There was statistically significant difference in urinary iodine content of pregnant women in different counties (cities, H = 88.32, P < 0.01). Conclusions:The qualified rate of iodized salt, the coverage rate of iodized salt and the consumption rate of qualified iodized salt in key populations of Yunnan Province are more than 90%, and the iodized salt supply is good. Iodine nutrition of children aged 8 - 10 years old is at an appropriate level (100 - 199 μg/L); iodine nutrition of pregnant women is in an state of iodine deficiency ( < 150 μg/L). It is suggested to strengthen IDD monitoring and health education among key populations, improve residents' awareness of disease prevention, and make scientific iodine supplementation.
ABSTRACT
OBJECTIVE: To analyze the current status of silica dust hazard in workplaces of Jiangxi Province. METHODS: The level of silica dust in the air of workplaces, occupational health examination of the dust-exposed workers and diagnosis of occupational disease in 1 557 enterprises in Jiangxi Province were investigated and analyzed. RESULTS: The 1 557 enterprises were included in eight industries, and the main types of enterprises were non-coal mining, ceramic products manufacturing and stone processing industry(a total of 85.16%). There were 4 029 jobs/positions that were involved in exposure to silica dust in these workplaces. Among them, the exposure concentration of time weighted average(C_(TWA)) of total dust and respirable dust exceeded 21.52% and 20.55%, respectively. The posts where the total dust and respirable dust that exceed the standard were found in the quartz sand processing industry, non-ferrous metal smelting industry and stone processing industry, that were the top three among the eight industries(all P<0.01). Among the 828 posts with C_(TWA) of respiratory dust exceeding the standard, the C_(TWA) exceeding rate of mild-, moderate-and high-hazardous jobs were 3.87%(156/4 029), 1.66%(67/4 029) and 15.02%(605/4 029), respectively. Among 23 643 dust-exposed workers, the detection rates of occupational contraindications and suspected silicosis were 2.06% and 1.51%, and the prevalence of silicosis was 1.21%. CONCLUSION: Silica dust hazard in workplaces of quartz sand processing industry, non-ferrous metal smelting industry and stone processing industry are serious in Jiangxi Province. The supervision and management of occupational health should be further strengthened to guarantee the occupational health of workers.
ABSTRACT
Objective@#To investigate the current situation of clinical nurses′ caring behavior and patients′ perception of caring, to understand the level of nursing care behavior and analyze the influencing factors, and to discuss the relationship between patients′ perception of caring and clinical nurses′ caring behavior.@*Methods@#The convenience sampling method was used to investigate clinical nurses and inpatients from October to December 2018. The Caring Behavior Checklist was used to observe nurses' nursing care behavior, and the Client Perception of Caring Scale was used to investigate patients' perception of Caring.@*Results@#A total of 132 clinical nurses were observed and 132 patients were investigated. The score of verbal caring behavior was (3.36±1.44) points (out of a possible 7 points), and the score of non-verbal caring behavior was (2.33±1.07) points (out of a possible 5 points).The overall score of Caring Behavior Checklist was (5.70±2.03) points (out of a possible 12 points). Nurses aged 26-35 (6.42±2.07) points had a higher level of nursing care behavior than nurses of other age groups, and the difference was statistically significant (F=3.902, P<0.05).N1 nurses had a higher level of nursing care behavior than nurses at other levels, it was (7.72±2.30) points, and the difference was significant (F=14.290, P<0.05). There was no significant difference in caring behavior level among nurses with different gender, departments, education backgrounds, academic titles and nursing ages (P>0.05). The overall score of Client Perception of Caring Scale was (43.49 ±3.84) (out of a possible 60 points), and there was a high positive correlation between client perception of caring and nursing care behavior (r=0.720, P<0.05).@*Conclusions@#The level of clinical nurses′ caring behavior is low, and the training of caring knowledge, belief and behavior should be carried out to promote nurses′ caring behavior, so as to further improve client perception of caring.

ABSTRACT
Objective To investigate the current situation of management of institutions of schistosomiasis prevention and control in Hubei Province so as to explore the probable competency building standards for these institutions at the county and township levels. Methods By using a combination of quantitative and qualitative methods the institutions of schistosomiasis prevention and control at county and township levels were investigated for the institutional setup staffing and fulfillment func-tions since the reform of 2004. Results Among 63 schistosomiasis endemic counties cities districts of Hubei Province there were 26 independent schistosomiasis control institutions 41.27% there were 24 institutions which were incorporated in-to CDC 38.10% and there were no institutions in 13 counties 20.63% . Among 518 endemic towns there were 299 institu-tions 57.72% . The total staffing size were 1 932 but there were 1 586 82.09% people actually working in the post and therefore there were 346 17.91% empty positions. The average rates of carrying out the six functions were 91.48%-71.19%but only 19.23%of the institutions participated in the comprehensive schistosomiasis control management project and its effect assessment. Conclusion According to the management model for schistosomiasis control institutions under the current institu-tional mechanisms we need a rigorous industry standard to constrain guide and standardize the management and capacity-building of the institutions in different historical periods.
