Objective: To investigate the changes of urinary S100B protein concentrations and their relationship with brain damage in preterm infants there of . Methods: The urinary S100B protein of 84 preterm infants and 26 full term infants, which were used as control, were measured at 24 h and 120 h after birth. At the same time, routine clinical observations, neurologic patterns and ultrasound screens were recorded. The value of urinary S100B protein and brain damage were evaluated in preterm infants with different gestational age. Results: The differences of urinary S100B protein were statistical significance between the different gestations. The levels of urinary S100B protein were higher in preterm infants, whose gestations were lower than 32 W, than those of other groups. The levels of S100B protein were significantly higher in samples of 27 peri-intraventricular hemorrhage (PIVH) and 3 peri-ventricular leukomalacia(PVL) than those in samples without brain damage( P ＜ 0.05). The S100B levels were significantly higher in urine of 10 preterm infants with polycethemia than those in infants without brain damages. In addition, the S100B levels were different in urine of preterm infants with different prognosis. The S100B levels were significantly higher in urine of infants who died or deteriorated than those of others(P ＜ 0.05). Conclusion: There is an evident trend of decrease in urinary S100B protein concentration with increasing gestational age. It will be helpful to identify preterm infants with PIVH,PVL and high risk of brain damages by measurement of S100B protein in urine early after birth, which indicates further inspection, provides protective treatment and enhances follow up.

Objective:To learn about the epidemiological and spatial clustering characteristics of brucellosis in Shandong Province, and to provide a reference for scientific prevention and control of brucellosis.Methods:The epidemic data of human brucellosis in Shandong Province from January 2015 to December 2020 were collected from the Infectious Disease Reporting Information Management System of China Disease Control and Prevention Information System, and the data were analyzed by descriptive epidemiology and spatial clustering analysis.Results:A total of 18 811 cases of human brucellosis were reported in Shandong Province from 2015 to 2020, and the average annual incidence rate was 3.16/100 000. Human brucellosis occurred in every month of the year, and the peak incidence was from March to August, accounting for 66.31% (12 474/18 811). The top 5 counties (districts) with average annual incidence rates were Lijin County (32.39/100 000), Kenli District (11.02/100 000), Wudi County (10.35/100 000), Zhanhua District (9.59/100 000) and Shanghe County (8.80/100 000). There were 13 436 males and 5 375 females, with a male-female sex ratio of 2.50 ∶ 1.00; the age was mainly concentrated in 30-69 years old, accounting for 83.23% (15 656/18 811); farmer was the main occupation, accounting for 85.82% (16 144/18 811). The results of global spatial autocorrelation analysis showed that the annual incidence rates of brucellosis in Shandong Province showed a spatial clustering distribution from 2015 to 2020; and the local spatial autocorrelation analysis showed that the high incidence of human brucellosis was mainly concentrated in the north of Shandong Province.Conclusions:The incidence of brucellosis in Shandong Province is mainly concentrated in spring and summer, most of them are farmers, and the high incidence areas have spatial clustering. Key prevention and control measures should be taken for high incidence seasons, high-risk population and northern high clustering areas to reduce the incidence of brucellosis.

【Objective】 To evaluate the screening efficacy and practical value of the portable microfluidic biochemical analyzer in the detection of blood donors before blood donation. 【Methods】 Blood donor samples, clinical blood samples and constant quality control products were collected. Referring to the documents of ISO15189 and National Health Industry Standard, the precision and accuracy of hemoglobin (Hb) and alanine aminotransferase (ALT) were verified and compared with other detection systems. 【Results】 The MS200 biochemistry instrument has an intra-batch precision of 1.40% to 1.46%, inter-batch precision of 1.91% to 1.94%, and correctness bias of -0.9% to -1.3% for Hb test, and an intra-batch precision of 3.77% to 4.86%, inter-batch precision of 4.92% to 6.02%, and correctness bias of -3.0% to -4.8% for ALT test, which were within the range of quality requirements of industry standard. Comparison of Hb test results between MS200 biochemistry and Hb201 analyser on 1 189 peripheral blood samples from donors showed no statistically significant difference (P>0.05). 65 samples showed positive correlation between MS200 biochemistry and XS-900i automated hematology analyzer on Hb test results (R²=0.986, P=0.000). Correlation analysis of all the results of ALT detection by MS200 biochemical analyzer and AU480 biochemical analyzer in 1 065 samples showed a positive correlation (R²=0.965, P=0.000). The elevated ALT samples did not affect the Hb test results, and the samples with abnormal Hb value did not affect the ALT test results, with no interference between the two items in the detection. 【Conclusion】 The MS200 biochemical analyzer based on microfluidic technology has reliable methodological performance and can meet the need of pre-donation testing.
