ABSTRACT

Human microbiota is composed of bacteria, viruses, fungi and other microorganisms, which are distributed in the oral cavity, nasal cavity, intestine, vagina and skin, etc. Human microbiota plays a pivotal role in the metabolism, immunity, hormones and homeostasis of the host. It can protect the host and maintain the homeostasis, and provoke the incidence of inflammation and tumors. Microbiota has been found to modulate the efficacy and toxicity of chemotherapy and immunotherapy for certain types of tumors. Nevertheless, large-scale studies in the context of radiation therapy have not been performed. In this article, the relationship between the microbiota and the radiotherapy response and toxicity changes of cancer patients was summarized, aiming to develop the optimal treatment plan for patients, and provide evidence for the prevention and treatment of radiotherapy-induced injury.

ABSTRACT

BACKGROUND@#Most Chinese migrants have been faced with obstacles to getting access to local public health services. Young migrants among internal migrants make a major contribution to the economy. However, the establishment of their health records has been ignored. This research was aimed at exploring the status and associated factors of the establishment of health records among young Chinese migrants.@*METHODS@#Data were obtained from the 2017 China Migrants Dynamic Survey (CMDS). Chi-square test and binary logistic regression were performed to investigate the associated factors of the establishment of health records among young Chinese migrants.@*RESULTS@#Approximately 30.2% of young migrants had their health records established in inflow communities. Urban residence, medical insurance (insured), and lower average monthly household income were attributed to the establishment of more health records. Young migrants who were in northeast China and across provinces and immigrated for working or engaging in trade were less likely to have health records established. Young migrants who participated in social activities and public affairs activities and took type of people in touch as natives in the inflow area showed a higher possibility of establishing health records. Meanwhile, receiving health education and hearing about national basic public health services (BPHSs) were beneficial for establishing the health records of more young migrants.@*CONCLUSION@#This study showed that the health records of young migrants had a relatively low establishment rate. Sociodemographic and migration characteristics, health status, public health services, and social integration factors were all related to the health record establishment of young Chinese migrants.

ABSTRACT

BACKGROUND@#Limited published research has examined the relationships of negative life events and coping styles with sleep quality in Chinese junior high school students. We aimed to investigate the prevalence of poor sleep quality and to clarify the role of coping styles between negative life events and sleep quality.@*METHODS@#A cross-sectional study of 3081 students was conducted in Ganzhou City, Jiangxi Province, Southeastern China. Adolescent Self-Rating Life Events Checklist, Simplified Coping Style Questionnaire, and Pittsburg Sleep Quality Index were applied to assess negative life events, coping styles, and sleep quality, respectively. Descriptive analyses, independent-samples t tests, one-way analyses of variance, Pearson correlation analyses, and structural equation modeling (SEM) were applied to analyze the data.@*RESULTS@#The prevalence of poor sleep quality was 26.7%. Negative life events (B = 0.038, P 0.05). The association between negative life events and sleep quality was mediated by negative coping styles.@*CONCLUSIONS@#Our results indicated that poor sleep quality was common in these Chinese adolescents. Negative life events and negative coping style were associated with an increased prevalence of poor sleep quality, while the positive coping style was related to a decreased prevalence of poor sleep quality. A negative coping style mediated the association between negative life events and sleep quality.

ABSTRACT

Objective@#This study aims to explore the relationships of family functioning, general well-being, and exercise with psychological distress.Furthermore, we investigated the special roles of general well-being and exercise on the association between family functioningand psychological distress. @*Methods@#Of 769 end-stage renal disease (ESRD) patients participated in the cross-sectional study which consisted of the 12-item GeneralHealth Questionnaire (GHQ-12), the Family APGAR Scales, and the General Well-Being Schedule. The collected data were analyzedusing multiple linear regression analysis and path analysis. @*Results@#The prevalence of psychological distress was 72.3%. Family functioning, general well-being and exercise were associated factorsof psychological distress (p<0.05). The indirect effect of family functioning on psychological distress was partially mediated by generalwell-being (Effect=-0.08, 95% CI=-0.11, -0.04). In addition, the effect of family functioning on general well-being was moderated byexercise (Index=-0.092, SE=0.033, 95% CI=-0.159, -0.029). @*Conclusion@#The prevalence of psychological distress among ESRD patients was high. Family functioning, general well-being and exercisewere associated with psychological distress. Family functioning could affect psychological distress partially by affecting general wellbeing.Furthermore, exercise had a significant moderating effect on the relationship between family functioning and general well-being.Psychiatry Investig 2020;17(4):356-365

ABSTRACT

Objective MRI and MR hydrogen proton spectroscopy (1H-MRS) were used to detect the abnormal signal and alteration of metabolites, in order to explore the efficacy of these method in evaluating the damages of central nervous system (CNS) induced by occupational manganese exposure.Methods Eighteen workers exposed to manganese without any manganism symptoms, 12 workers with slightly chronic manganese poisoning, and 19 healthy workers were scanned using routine MRI sequence and 1H-MRS.The blood manganese concentration was also collected for each subject.On cerebral axial T1 WI,the signal intensities of ipsilateral globus pallidus and frontal white matter were measured in the visually brightest area (try to select the signal homogeneous region), and the globus pallidus index (PI) was then calculated.The 1H-MRS data was calculated to get the values of the peak height of N-acetylaspartate (NAA), choline (Cho), inositol (mI) and creatine (Cr) and the ratios of NAA/Cr, Cho/Cr, and mL/Cr were also calculated.One way ANOVA was used to compare the values of PI, NAA/Cr, Cho/Cr, mI/Cr and MnB among the three groups, and the correlations between PI and the time span of manganese exposure or blood manganese concentration were analyzed by Pearson correlation analysis.Eight workers exposed to manganese were followed up one year, and their PI , NAA/Cr before and after follow-up were compared by t test.Results Fourteen of 18 cases exposed to manganese without any manganism symptoms showed symmetrically high intensity signal on T1 WI, while the T2 WI were normal.No high signal intensity was observed on T1WI in any of the healthy workers or manganese poisoning workers.We found that the average PI in manganese exposed group (1.16 ±0.09) was significantly higher (F =24.79 ,P =0.O00)than those of the poisoning ( 1.05 ± 0.07 ) and control groups ( 1.01 ± 0.05 ).The blood manganese concentration in manganese exposed group, the poisoning group and the control group were (0.051 ±0.024), (0.047 ±0.018 ), ( 0.043 ± 0.020 ) μg/ml respectively, which was not significantly different ( F = O.623, P =0.541 ) and did not exceed the upper limit of normal reference value ( < 0.10 μg/ml ).There was a significantly correlation between PI and the time span of manganese exposure ( r = 0.67, P = 0.002 ),however, there was no correlation between PI and blood manganese concentration ( r = 0.20, P = 0.427 ).Furthermore, the NAA/Cr ratio decreased variously in the manganese poisoning group ( 1.22 ± 0.07 ) which was significantly lower( F = 4.120, P = 0.023 ) than those of the poisoning( 1.33 ± 0.13 ) and control groups ( 1.31 ±0.13).No statistical significanees were found in the ratios of Cho/Cr and mI/Cr among these three groups(P>0.05).No obvious changes of the PI and NAA/Cr were found in the 8 manganese exposed workers after 1 year follow-up.Conclusion Manganese exposure could lead to the high intensity signal on T1 WI, therefore the increased PI may be the biomarkers of central nerve system damages caused by the occupational manganese exposure.

ABSTRACT

BACKGROUND: Diabetic retinopathy is a commonly chronic-vascular complication in a course of diabetes mellitus (DM), and its relation with apoptosis and changes of ion level needs to be proved.OBJECTIVE: To observe apoptosis and changes of Na+ and K+ contents in retinal tissue of DM rats.DESIGN: Randomized controlled study.SETTING: Department of Ophthalmology, Liuzhou Municipal People's Hospital.MATERIALS: The experiment was completed at the Department of Ophthalmology, Liuzhou Municipal People's Hospital. A total of forty adult male Wistar rats, aged 20 months, weighing 320-350 g, were provided by Animal Center of Medical College Affiliated to Sun Yat-sen University.METHODS: Forth Wistar rats were randomly divided into control group and experimental group with 20 in each group. Streptozotocin was used to induce DM in the experimental group. Apoptosis and changes of Na+ and K+ contents in retinal tissue were measured on the 4th, 6th, 12th and 16th weeks after DM onset. Rats in the control group were injected only with the same volume of citrate buffer solution. Then, correlations on the aspect of fasting blood glucose (FBG), hemoglobin glycosylation (HbAlc), Na+ and K+ contents and DM course were analyzed between the two groups.MAIN OUTCOME MEASURES: ① Na+ and K+ contents; ② FBG concentra tion and HbAlc level; ③ changes of apoptosis; ④ correlations among markers.RESULTS: Apoptosis could be detected in retinal tissue in the experimental group at 4 weeks after DM onset, and with course elongating, level of apoptosis was aggravated gradually. Na+ concentration was increased in retinal tissue, but K+ concentration was decreased (P < 0.01 or 0.05). Levels of apoptosis in retinal tissue in the experimental group were positive correlation with FBG concentration, HbAlc level, Na+ content and DM course (r=7.584, 7.844, 7.369, 6.246; P < 0.01); however, they were negative correlation with K+ content in retinal tissue (r=7.658, P < 0.01).CONCLUSION: There are apoptosis and abnormal Na+ and K+ contents in retinal tissue of DM rats. Moreover, these changes may be one of pathological bases of diabetic retinopathy.

ABSTRACT

Objective To observe the hypoglycemic effect of total flavonoids from mulberry tree leaf (MTF) on diabetic rats and the effect of MTF on disaccharidases from rats. Methods Diabetic rats were treated with MTF, and then the change of blood glucose of these rats was observed; the brush border membrane from the small intestine of rats was stripped and homogenized, which was incubated with MTF and disaccharides, and the inhibitory rate of MTF on disaccharidases was determined. Blood samples from portal and peripheral veins were separately collected at 30, 60, 120 min after maltose solution was infused into small intestine in vivo, then the difference of blood glucose concentration between portal and peripheral veins was determined. Results MTF exerted a hypoglycemic effect on diabetic rats by inhibition of disaccharidases, the inhibitory rate of sucrase, maltase and lactase was 68.0%, 47.1%, 27.8% respectively, the difference of blood glucose concentration between portal and peripheral veins was also reduced. Conclusion The hypoglycemic effect of MTF on diabetic rats is probably via the inhibitory effect on small intestine disaccharidases in rats.
