Objective In order to understand the depression situation of the hospitalized tuberculosis patients.Methods Zung depression was used as a tool for assessment,the objective of 130 patients hospitalized for tuberculosis survey.Results 58.5% of the hospitalized tuberculosis patients showed symptoms of depression,compared with the secondary and 3 care patients,the rate was high among the level care patients,meaningful differences(P

OBJECTIVETo investigate the mutations of phenylalanine hydroxylase (PAH) gene in the cases of classical phenylketonuria (PKU).

METHODSThe exons 3-12 of the PAH gene in 32 PKU patients from Inner Mongolia were studied by using PCR-single strand conformation polymorphism technique and DNA direct sequencing.

RESULTSFourteen point mutations were identified. The frequencies of mutations were R243Q (12/64), Y356X (6/64), Y204C (5/64), R261Q (2/64), Y161S (2/64), R252Q (1/64), R111X (2/64), D282G (1/64), S303P (1/64), G239D (1/64), R413P (1/64), IVS7nt+2 (2/64), IVS4nt+3 (1/64) and IVS9nt+34 (2/64). Two novel mutations IVS4nt+3 (G>C) and IVS9nt+34 (G>A) were first found. The S303P (T>C) and D282G (A>G) were first documented in Chinese PAH gene.

CONCLUSIONThis study demonstrated the variety of the mutation type PAH gene of PKU in Inner Mongolia population, and confirmed that R243Q, Y356X, Y204C were the hot spots of PAH gene mutation.

Objective:To learn about the operation of arsenic reduction and water improvement projects and the present situation of arsenic level in drinking water in drinking water type endemic arsenic poisoning areas in Jinzhong City, Shanxi Province.Methods:From May to August 2023, in accordance with the requirements of the "Investigation Plan for Arsenic Content in Drinking Water of Residents in Arsenic Exposed Areas of Shanxi Province", 29 high arsenic villages in the drinking water type endemic arsenic poisoning historical areas of Pingyao County, Jiexiu City and Qi County in Jinzhong City, Shanxi Province were selected as monitoring villages to investigate the operation of water improvement projects. The drinking water samples of village residents were collected and water arsenic level was measured by hydride atomic fluorescence spectrophotometry. At the same time, monitoring of the operation of water improvement projects and water arsenic level for residents within adjacent local areas were carried out in townships where 29 high arsenic villages located.Results:In 2023, a total of 29 high arsenic villages in 3 counties (cities) of Jinzhong City, Shanxi Province were monitored, all of which had undergone water improvement and all water improvement projects were operating normally. The range of water arsenic level was 0.000 - 0.047 mg/L, with 27 high arsenic villages had water arsenic level < 0.01 mg/L. A total of 81 natural villages within the adjacent local areas of high arsenic villages in Jinzhong City were monitored, all of which had undergone water improvement and the water improvement projects were operating normally. The range of water arsenic level was 0.000 - 0.043 mg/L, and there were 4, 7, and 2 natural villages in Pingyao County, Jiexiu City and Qi County with water arsenic level ranging from 0.01 to 0.05 mg/L.Conclusions:All high arsenic villages in Jinzhong City, Shanxi Province have completed water improvement, and the water improvement projects are operating normally. The water arsenic level in most high arsenic villages meets the national drinking water standard (< 0.01 mg/L).

Objective:To analyze the changes in the number and workload of pediatricians, for evidences in further optimizing the allocation of pediatrician resources and formulating relevant policies in China.Methods:According to data from the National Bureau of Statistics and the " China Health and Health Statistics Yearbook", descriptive analysis was made to investigate the changes in the number and workload of pediatricians in China from 2010 to 2019.Results:During 2010 and 2019, the number of pediatric practitioners(assistants) increased from 115 800 to 158 500, and the growth rate was faster than that of the children aged 0-14 years, but slower than that of overall medical practitioners(assistants). The number of pediatric practitioners(assistants) per thousand children in China had grown steadily from 0.52 to 0.67, compared with the burden and the workload of medical practitioners nationwide, the workload of pediatricians was still relatively heavy.Conclusions:The number of pediatricians had increased gradually between 2010 and 2019, and the effects of various policies began to work, while the workload was still heavy. It is recommended to further develop a salary system and supporting policies in line with the characteristics of pediatrics sector, and focus on such problems as unbalanced and inadequate distribution of pediatricians.
