Correlation between stomach disharmony and daily diets among students of Chinese medicine colleges and universities in China / 中国基层医药

Objective:To analyze the correlation between gastric disharmony and daily eating behaviors in college students, and to provide intervention measures for improving gastric disharmony among college students.Methods:From April 10 to 30, 2021, 3 825 college students from five Chinese medicine colleges and universities in China were selected for this study using the multi-level sampling method. The information regarding college student's general situation, daily eating behavior, and stomach disharmony was collected by questionnaire.Results:A total of 3 700 valid questionnaires were collected, with an effective response rate of 96.73%. The average age was (20.0 ± 3.0) years, and 66.41% of college students included in this study were female. Students with different characteristics had different gastric disharmonies and eating behaviors, and gastric disharmony was correlated with eating behavior. Multivariate analysis results showed that snacking ( OR = 1.11, 95% CI: 1.02-1.21), partial eclipse ( OR = 1.12, 95% CI: 1.00-1.26), picky eaters ( OR = 1.23, 95% CI: 1.08-1.41), and supper ( OR = 1.19, 95% CI: 1.04-1.36) were positively correlated with gastric disharmony. Eating regular meals ( OR = 0.86, 95% CI: 0.79-0.94) and 80% fullness ( OR = 0.89, 95% CI: 0.81-0.98) were negatively correlated with gastric disharmony. Conclusion:Poor eating behaviors may be an important factor leading to gastric disharmony.

Hospitalization rates for influenza-associated severe acute respiratory illness in children younger than five years old in Suzhou of China, 2016-2018 / 中华预防医学杂志

We analyzed the influenza surveillance data of Children′s Hospital of Suzhou University from 2016 to 2018 and estimated the hospitalization burden of children under 5 years old due to influenza infection in Suzhou. The results showed that the influenza virus positive rate of 1 451 severe acute respiratory infection (SARI) cases in Children′s Hospital of Suzhou University was 13.6% (95%CI: 11.8%-15.3%; 197 cases), among which the influenza pandemic intensity in 2017-2018 was relatively high, and A/H1N1 was the main pandemic virus. It was estimated that the hospitalization rate of influenza-related SARI in children under 5 years old in Suzhou was 6.9‰ (95%CI: 6.6‰-7.2‰), among which the hospitalization rate of children aged<6 months was higher, up to 11.4‰ (95%CI: 9.9‰-12.8‰).

Determination of 19 Organochlorine Pesticide Residues in Sargassum Fusiforme by GC-MS / 中国药师

Objective:To establish a GC-MS method for determing 19 organochlorine pesticide residues in sargassum fusiforme. Methods:Nineteen organochlorine pesticide residues were simultaneously determined by GC-MS, and the established method was vali-dated. The HP-5 gas chromatography column (30 m × 0. 25 mm,0. 25 μm) was used. The column temperature was programming in-creased with initial temperature of 70℃, maintaining for 1min, then raising to 180℃ with a rate of 15℃·min-1 ,and then raised to 280℃ with a rate of 4℃·min-1 to keep 7min. The inlet temperature was 240℃. The MS detector was used with EI source at 230℃, and analysis mode was multiple reaction monitoring. Results:Sargassum fusiforme was analyzed. The separation degree of the standard and samples met the requirements. The recoveries of the organochlorine pesticides were 72%-127% except for hexachlorobenzene, and the relative standard deviation also met the requirements. The experimental results showed that the 19 organochlorine pesticides were not detected out in sargassum fusiforme. Conclusion: The method provides the technical parameters for the determination of organo-chlorine pesticide residues in sargassum fusiforme.
