RESUMEN
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.
RESUMEN
Objective:To investigate the correlation between unhealthy dietary behaviors and traditional Chinese medicine constitution among students from colleges and universities of traditional Chinese medicine.Methods:College students from Shandong University of Traditional Chinese Medicine, Anhui University of Chinese Medicine, Henan University of Chinese Medicine, Shaanxi University of Chinese Medicine and Gansu University of Chinese Medicine were collected during April 10-30, 2021 and grouped taking classes as units. Research subjects were obtained by multistage sampling. Their dietary behaviors, traditional Chinese medicine constitution and demographic characteristics were surveyed using questionnaires. Statistical analysis was performed using SPSS23.0 software.Results:A total of 3825 college students were investigated and 3 700 valid questionnaires (96.7%) were collected. Peaceful constitution was detected in 7.9% of included college students. There was significant difference in peaceful constitution among studies of different sexes and different body types ( P < 0.05). There were significant differences in attention to diet, physical exercise and body weight control, out-of-control diet, excessive eating and drinking, denying body shape, and dissatisfaction with body shape between patients with peaceful and unbalanced constitutions. Multivariate analysis showed that attention to diet ( OR = 1.38, 95% CI: 1.14-1.68), physical exercise and body weight control ( OR = 1.19, 95% CI: 1.03-1.39), dissatisfaction with body shape ( OR = 1.26, 95% CI: 1.10-1.45) were conducive to the development of peaceful constitution. Conclusion:Students from colleges and universities of traditional Chinese medicine have a low proportion of developing peaceful constitution. Dietary behaviors may be an important factor that affects the development of peaceful constitution.
RESUMEN
Pyrroloquinoline quinone (PQQ) is a bacterial dehydrogenase coenzyme. PQQ can promote body growth and regulate the function of free radical level of the body. It could be applied in food, medicine and other fields. Due to the extremely high cost of chemical synthesis, the production of PQQ by microbial fermentation attracted more and more attention. At present, the production titer of PQQ by fermentation method is too low to achieve industrial application. Due to the lack of a thorough understanding of the PQQ biosynthesis and its regulation mechanisms, and the lack of necessary genetic engineering modification methods for wild type strains, metabolic engineering of microorganisms to enhance PQQ production still lacks essential requirements. In this study, a PQQ-producing bacterium, Methylobacterium extorquens I-F2, was employed as a model strain. By integration of Atmospheric and room temperature plasma (ARTP) mutagenesis, flow cytometry sorting and high-throughput screening strategies, optimization of sample preparation and flow sorting process, a high-titer PQQ mutant strain was obtained. The titer of PQQ was increased by 98.02% compared with that of M. extorqunens I-F2. The process described here showed that the combination of the flow cytometry with high-throughput screening method can be used to obtain high-titer mutants more simply and rapidly, compared with genetic engineering and traditional screening methods.

RESUMEN
OBJECTIVE@#To investigate the epidemiology of EBV in adenoidal hypertrophy and chronic tonsillitis and discuss the affection of EBV on the nosogenesis of adenoidal hypertrophy and tonsillitis of children.@*METHOD@#Fifty-two children with chronic tonsillitis and/or adenoidal hypertrophy had the operations of the tonsillectomy and/or the adenoidectomy. These tissues resected and plasma of all cases were detected to find EBV-DNA by RQ PCR.@*RESULT@#The infection rate of EBV in the tissues of adenoidal hypertrophy and tonsillitis of children was 51.9%. The boys' infection rate of EBV was 50.0%, and the girls' infection rate of EBV was 55.6%, which had not significantly different. The EBV infection rate in the tissues of tonsillitis was 40.4%, The EBV infection rate in the tissues of adenoidal hypertrophy was 48.9%, which had not significant difference. The school age group (7- to 14-years-old) presented higher infection rate of EBV in the tissues of adenoid and tonsil (65.5%) than the pre-school children group (2- to 6-years-old) (34.8%). Comparing the copies numbers of EBV-DNA in the different degrees of adenoidal hypertrophy, we found that the copies numbers of EBV-DNA in the severe hypertrophy group were higher than the midrange and slight hypertrophy groups (P<0.05). Meanwhile we detected EBV-DNA in these childrens' blood plasma by RQ-PCR. No blood plasma was detected EBV-DNA copies higher than normal (< 1 x 10(3) copies/ml).@*CONCLUSION@#The tissues of adenoidal hypertrophy and tonsillitis had same sensitivity to EBV. There was not significant difference between the infection rates of the boys and girls with adenoidal hypertrophy and/or tonsillitis. With these children growing up and the course of diseases prolonging, the infection rate of EBV increased correspondingly. There was a certain correlation between the hypertrophy of adenoid and EBV. There were no EBV-DNA fragments in blood plasma of the children with adenoidal hypertrophy and/or tonsillitis. So there were essential different between benign hyperplasia and nasopharyngeal carcinoma.
