Antioxidant aromatic compounds from Amomum villosum and target prediction of active ingredients.

The dried fruit of Amomum villosum is an important spice and medicinal plant that has received great attention in recent years due to its high content of bioactive components and its potential for food additives and drug development. However, the stems and leaves of A. villosum are usually disposed of as waste. Based on the study of the fruits of A. villosum, we also systematically studied its stems and leaves. Fourteen aromatic compounds (1-14) were isolated and identified from A. villosum, including five new compounds (1-5) and nine known compounds (6-14). Among them, compounds 2-5, 8-10, 12-13 were obtained from the fruits of A. villosum, and compounds 1, 6-7,11, 14 were isolated from the stems and leaves of A. villosum. Based on chemical evidence and spectral data analysis (UV, ECD, Optical rotation data, 1D and 2D-NMR, and HR-ESI-MS), the structures of new compounds were elucidated. Furthermore, all compounds were tested for their effects on the survival rate of BV-2 cells in the presence of hydrogen peroxide. Among them, compound 5 showed antioxidant effects. Through network pharmacology screening and the cell thermal shift assay (CETSA), the Phosphoglycerate Mutase 5 (PGAM5) protein was identified as the antioxidant target of compound 5. Molecular docking results showed that compound 5 maintains binding to PGAM5 by forming hydrogen bond interactions with Lys93 and Agr214. In summary, A. villosum had potential medicinal and food values due to the diverse bioactive components.

Nutrient supplementation among pregnant women in China: an observational study.

OBJECTIVE: To clarify nutrient supplementation usage and primary source of information among pregnant women in China. DESIGN: This cross-sectional study used information on nutrient supplementation and primary source of information collected via face-to-face interviews. Data on the usage of folic acid, Ca/vitamin D, Fe, vitamins, DHA and other dietary supplements were collected. Primary source of information was categorised as family/relatives, friends/co-workers, the Internet, books/magazines, television/radio, doctors, other people and oneself. SETTING: Maternal and Child Health Hospital in Chengdu, China. PARTICIPANTS: One thousand eighty-one Chinese pregnant women aged ≥20 years with singleton pregnancies. RESULTS: In all three trimesters of pregnancy, usage was highest and most stable for folic acid (81·7 %), followed by vitamins (vitamin A, B-group vitamins, vitamin C and multivitamins; 75·0 %), whereas Ca/vitamin D (51·4 %) and Fe (18·1 %) usage was low, potentially indicating a deficiency risk. All supplementation usage percentages increased with pregnancy duration (P < 0·05). Notably, approximately 10 % of the pregnant women in our study did not use any nutrient supplementation, and this was especially common in early pregnancy. More than 50 % of the women reported getting information on nutrient supplementation from family members, and about 30 % reported getting this information from doctors. CONCLUSIONS: Among pregnant women in China, awareness about nutrient supplementation increases as the pregnancy progresses, but some types of nutrient supplementation (such as Ca/vitamin D and Fe) remain at low levels. It is necessary to pay more attention to the health education of pregnant women in China, and the influence of family members should be emphasised.

Patient satisfaction in China: a national survey of inpatients and outpatients.

OBJECTIVES: Patient satisfaction is an important indicator of hospital healthcare quality. Little up-to-date information of patient satisfaction in China is available. This study attempts to gain a holistic understanding of patient satisfaction in China and identify the key antecedents of patient satisfaction. DESIGN: A cross-sectional national survey was conducted in 2018. SETTING: Hospitals in 27 provinces and 4 municipalities in 4 regions of China. PARTICIPANTS: A random sample of 15 699 patients who visited 1304 hospitals were surveyed, with around 500 from each of the 27 provinces and 4 municipalities. PRIMARY AND SECONDARY OUTCOME MEASURES: The Hospital Consumer Assessment of Healthcare Providers and Systems questionnaire was used to measure patients' overall satisfaction and willingness to recommend the hospital. RESULTS: We found significant variation in overall patient satisfaction but little variation in hospital recommendation across the four broad regions. Moreover, we examined determinants of patient satisfaction and their likelihood to recommend the hospital. The overall satisfaction for inpatients and outpatients is commonly influenced by communication with doctors (inpatient: ß=0.524, p<0.001; outpatient: ß=0.541, p<0.001), hospital cleanness (inpatient: ß=0.165, p<0.05; outpatient: ß=0.144, p<0.001) and acceptable charges (inpatient: ß=1.481, p<0.001; outpatient: ß=1.045, p<0.001). Both inpatients and outpatients are more likely to recommend the hospital if there are communication with doctors (inpatient: OR=1.743, p<0.001; outpatient: OR=1.647, p<0.001), acceptable charges (inpatient: OR=2.660, p<0.001; outpatient: OR=2.433, p<0.001). Outpatient satisfaction and hospital recommendation are also influenced by time spent with doctors (satisfaction: ß=0.301, p<0.001; recommend: OR=1.430, p<0.001) and waiting time (satisfaction: ß=-0.318, p<0.001; recommend: OR=0.844, p<0.001). CONCLUSIONS: There are regional differences of patient satisfaction in China. Patient satisfaction is influenced by a variety of hospital factors and province/municipality factors. The influencing factors of patient satisfaction may not motivate patients to recommend the hospital.
