ABSTRACT

Objective::To analyze and identify the metabolites of major components of Shaoyao Gancaotang in urine and feces of normal and polycystic ovary syndrome (PCOS) rats, and to explore the effect of PCOS on the metabolism of Shaoyao Gancaotang. Method::Female SD rats were randomly divided into normal group and PCOS group. PCOS rat model was prepared by administration of letrozole solution for 21 days, and the estrous cycle of rats was observed. UHPLC-QTRAP-MS/MS technique and LightSight 2.3 software were used to analyze and identify the metabolites of major components of Shaoyao Gancaotang in urine and feces of normal and PCOS rats. The mobile phase was water-methanol for gradient elution, the flow rate was 0.3 mL·min-1, electrospray ion source was employed under negative ion mode. Result::Phase Ⅰ and phase Ⅱ reactions mainly occurred in drug metabolism. A total of 27 metabolites were detected in urine of normal rats, and 34 metabolites were detected in urine of PCOS rats. A total of 29 metabolites were detected in feces of normal rats, and 27 metabolites were detected in feces of PCOS rats. Conclusion::The metabolites in the urine of PCOS rats are more diverse than those of normal rats, and the disease status of PCOS may affect the in vivo metabolic pathway of active ingredients in Shaoyao Gancaotang.

ABSTRACT

Objective:To investigate the effect of BTE system intensive training on upper limbs for cervical spinal cord injured patients in various courses. Methods:From June, 2019 to January, 2020, 60 inpatients with traumatic C6-7 spinal cord injury were selected into sub-acute group (one to two months after surgery, n = 15), recovery group (three to six months after surgery, n = 15), stable group (over six months after surgery, n = 15) according to the course of disease, and control group (over six months after surgery, n = 15). The control group received comprehensive rehabilitation, while the other groups received upper limbs intensive training on BTE system in addition, for four weeks. They were assessed with Upper Extremity Motor Score (UEMS) and Functional Independence Measure (FIM), meassured isometric peak torque (IPT) and isotonic extreme muscle endurance (IEE) of bilateral elbow extensors before and after treatment. Results:All the indexes improved after treatment (t > 3.500, P < 0.01), and they were significantly different among the groups (F > 9.257, P < 0.001), in which, it was the most of UEMS and IPT in the sub-acute group, and IEE and FIM in the recovery group. Conclusion:BTE system intensive training is effective on upper limbs after cervical spinal cord injury. Sub-acute patients may improve more in motor function and explosive power, while patients at recovery stage do better in endurance and activities of daily living. Even stable patients can benefit from it somehow.

ABSTRACT

Objective@#To understand the prevalence of eating behavior problems among preschool children in rural Hunan, and to explore its determinants, so as to provide a reference for solving their eating behavior problems.@*Methods@#A multistage stratified cluster sampling method was used to randomly select 3 288 preschool children aged 3-6 years and their caregivers from 24 kindergartens between August and November 2019. Eating behavior problems questionnaire survey and peripheral blood hemoglobin detection were conducted among the preschool children, and unconditional Logistic regression model was used to analyze the determinants.@*Results@#The total prevalence of eating behavior problems among preschool children in rural Hunan was 66.8%(2 195/3 288), and the three most common eating behavior problems were poor appetite(40.1%, 1 317/3 288), picky eating(43.6%, 1 434/3 288), poor eating habits(44.4%, 1 460/3 288), respectively. The risk factors for general eating behavior problems included left-behind children, caregiver occupation as professional and technical staffs, average daily static activity time≥3 hours, anemia, and second-hand smoke exposure, and older age and daily moderate/high intensity activities were protective factors. In the analysis of the three most common eating behavior problems: The risk factors for poor appetite included left-behind children, anemia, and second-hand smoke exposure, and daily moderate/high intensity activities was protective factors. The risk factors for picky eating included left-behind children, caregiver occupation as professional and technical staffs, high family income, average daily static activity time≥3 hours, and daily moderate/high intensity activities was protective factors. The risk factors for poor eating habits included left-behind children, caregiver occupation as professional and technical staffs, average daily static activity time≥3 hours, and older age and daily moderate/high intensity activities was protective factors.@*Conclusion@#The prevalence of eating behavior problems among preschool children in rural Hunan was high, which is influenced by age, left-behind, caregivers occupation, family income, activities, anemia, and second-hand smoke exposure.
