Relationship Between Maternal Negative Emotions and Feeding Patterns of Infants Aged 0-6 Months in Remote Rural Areas of Sichuan Province / 中国医学科学院学报

Objective To investigate the status of exclusive breastfeeding and bottle feeding in remote rural areas of Sichuan province and explore the relationship between negative emotions of mothers and feeding patterns of infants.Methods Multistage cluster sampling was employed to select the infants aged 0-6 months and their mothers in remote rural areas of Sichuan province.A self-designed questionnaire was used to collect the demographic characteristics of mothers and infants and the basic family information.The Chinese version of Depression Anxiety Stress scale was used to evaluate mothers' negative emotions,and the Breastfeeding Self-efficacy scale to assess the confidence level of mothers' behavior of adhering to exclusive breastfeeding.Results Totally 723 pairs of infants and their mothers were included.The exclusive breastfeeding and bottle feeding rates were 34.16% (247/723) and 57.54% (416/723),respectively.Mothers with depression tendency were less likely to adopt exclusive breastfeeding (OR=0.532,95%CI=0.291-0.974,P=0.041) and more likely to adopt bottle feeding (OR=1.877,95%CI=1.054-3.344,P=0.033).Further subgroup analysis of breastfeeding self-efficacy showed that in the group of low self-efficacy,the mothers with depression tendency were less likely to adopt exclusive breastfeeding (OR=0.461,95%CI=0.236-0.902,P=0.024) and more likely to adopt bottle feeding (OR=1.968,95%CI=1.047-3.701,P=0.036) than the mothers without depression tendency.In the group of high self-efficacy,mothers' depression,anxiety,and stress tendency had no significant correlation with infant feeding patterns (all P>0.05).Conclusions The mothers in the remote rural areas of Sichuan province are more likely to employ bottle feeding than exclusive breastfeeding.The mothers with stronger depression tendency demonstrate lower possibility of exclusive breastfeeding and higher possibility of bottle feeding.Breastfeeding self-efficacy may affect the association between maternal depression and infant feeding patterns.

Current Situation and Influencing Factors of Delay in Seeking Medical Treatment Among Residents in Rural Areas of Sichuan Province / 中国医学科学院学报

Objective To understand the current situation and explore the influencing factors of delay in seeking medical treatment for common symptoms of residents in the rural areas of Sichuan province. Methods In July 2019,multi-stage random sampling was carried out in Zigong city,Sichuan province,and the data were collected by face-to-face questionnaire interview.The residents who had lived at hometown for more than half a year in the past year and had seen a doctor in the most recent month were surveyed.Logistic regression was adopted to predict the influencing factors of delay in seeking medical treatment. Results A total of 342 subjects were enrolled,and the incidence of delay in seeking medical treatment was 13.45%(46/342).Compared with the young and middle-aged(<65 years)people,the elderly(≥65 years)people were more likely to have delay in seeking medical treatment (OR=2.187,95%CI=1.074-4.457,P=0.031).The rural residents who gave higher score of the overall quality of township health centers were less likely to have delay in seeking medical treatment (OR=0.854,95%CI=0.735-0.992,P=0.039). Conclusions The occurrence of delay in seeking medical treatment for common symptoms of rural residents in Sichuan province is low.Age and the overall quality evaluation of township health centers affect the occurrence of delay in medical treatment among the rural residents in Sichuan province.Efforts should be made to improve the awareness of disease prevention among the elderly in rural areas.The investment in health resources in township health centers should be increased to strengthen the introduction and training of talents.These measures can improve the health services in township health centers,guide residents to make timely use of health resources,and reduce the occurrence of delay in seeking medical treatment.

Apparent Diffusion Coefficient Histogram Analysis:Differentiation of Genetic Subtypes of Diffuse Lower-grade Gliomas / 中国医学科学院学报

To explore the utility of apparent diffusion coefficient(ADC)histogram analysis for differentiating genetic subtypes of diffuse lower-grade gliomas. A total of 55 patients with WHO grade Ⅱ/Ⅲ diffuse lower-grade gliomas who underwent preoperative routine brain magnetic resonance imaging and diffusion weighted imaging in our center were retrospectively evaluated.Among whom there were 14 patients with isocitrate dehydrogenase(IDH)wild-type gliomas(IDH group),19 patients with IDH-mutant 1p19q intact gliomas(IDH 1p19q group),and 22 patients with IDH-mutant 1p19q co-deleted gliomas(IDH 1p19q group).The whole-lesion ADC values derived from histogram analysis(including ADC,ADC,ADC5%,ADC10%,ADC25%,ADC50%,ADC75%,ADC90%,ADC95%,ADC,mode,range,skewness,kurtosis,standard deviation,inhomogeneity,and entrophy)were measured for each patient.All parameters between the different genetic subtypes were compared by using the Student's test or Mann-Whitney test.Receiver operating curve(ROC)analysis was used to assess the diagnostic performance of ADC histogram in distinguishing the different genetic subtypes. Compared with IDH group,the ADC75%(=0.021),ADC90%(=0.015),ADC95%(=0.014),ADC (=0.035),range(=0.009),standard deviation(=0.001)and inhomogeneity(=0.001)were significantly lower in IDH group;in contrast,the ADC (=0.031)and kurtosis(=0.020)of IDH group were significantly higher than those in IDH group.The ADC(=0.010),ADC5%(=0.016),ADC10%(=0.012),ADC25%(=0.007),ADC50%(=0.005),ADC75%(=0.015),and mode(=0.002)were significantly higher in IDH 1p19q group than in IDH 1p19q group.Inhomogeneity achieved the highest area under ROC(AUC)(0.811)in differentiating IDH gliomas and IDH gliomas,with a cutoff value of 0.229;the sensitivity and specificity were 85.7% and 73.2%.The mode achieved the highest AUC(0.744)in differentiating IDH 1p19q gliomas and IDH 1p19q gliomas,with a cutoff value was 1448.75×10 mm /s;the sensitivity and specificity were 57.9% and 90.9%. ADC histograms analysis may be helpful to differentiate genetic subtypes in lower-grade gliomas.

For oral feeding function, by Functional Oral Intake Scale, MD = 1.58, 95%CI 0.67 to 2.49. For quality of life, by Anderson Dysphagia Inventory, within three months, MD = 0.07, 95%CI -1.30 to 1.44; three to six months, MD = -1.74, 95%CI -3.40 to -0.07; six to nine months, MD = -1.36, 95%CI -3.15 to 0.42; by European Organization for Research on Treatment of Cancer Quality of Life Questionaire, within three months: a research displayed that the score was less in the training group than in the control group (P = 0.03), another research displayed that the score was more in the training group than in the control group (P < 0.05); three to six months, MD = 10, 95%CI 1.83 to 18.17; six to nine months, MD = 2.20, 95%CI -5.57 to 9.98; nine to twelve months, MD = -1.76, 95%CI -10.73 to 7.21. Conclusion:Swallowing rehabilitation can improve the swallowing function and the oral feeding function for the head and neck cancer patients, however, it is needed more evidence to support the improvement on the quality of life.

Hydroxydibenzoylmethane induces apoptosis through repressing ornithine decarboxylase in human promyelocytic leukemia HL-60 cells

Ornithine decarboxylase (ODC) is the rate-limiting enzyme in polyamine biosynthesis and a target for chemoprevention. Hydroxydibenzoylmethane (HDB), a derivative of dibenzoylmethane of licorice, is a promising chemopreventive agent. In this paper, we investigated whether HDB would inhibit the ODC pathway to enhance apoptosis in human promyelocytic leukemia HL-60 cells. We found ODC enzyme activity was reduced during HDB treatment. Overexpression of ODC in HL-60 parental cells could reduce HDB-induced apoptosis, which leads to loss of mitochondrial membrane potential (Deltapsim), through lessening intracellular ROS. Furthermore, ODC overexpression protected cytochrome c release and the activation of caspase-3 following HDB treatment. The results demonstrated HDB-induced apoptosis was through a mechanism of down-regulation of ODC and occurred along a ROS-dependent mitochondria-mediated pathway.
