Objective To provide effective reference for quality analysis of the chemical composition and extraction of astragalus separation process by comparing the extract of astragalus and it’s IR spectra. Methods The saponins and flavonoids in astragalus were firstly extracted by the method of circumfluence with ethanol as solvent and the residue of ethanol-extraction was then used to extract polysaccharides by distilled water. Fourier transform infrared spectroscopy (IR) combined with second derivative infrared spectroscopy was applied to quickly identify astragalus herbs powder, water extraction of astragalus, astragalus alcohol extraction and water extraction of the residue of ethanol-extraction. Results The powder and 70% ethanol extract, 80% ethanol extract were around at 1 735 cm-1 (carbonyl stretching vibration absorption peak) has a weak, broad absorption, while the absorption peak was less obvious in boiling water extraction. So the maln components of astragalus water extraction are polysaccharides and also contaln a small amount of water-insoluble flavonoids. Alcohol extraction malnly contalns saponins and flavonoids, and flavonoid extract volume increases with increasing alcohol concentration in a certaln range.Conclusion This method can be a quick and easy identification for astragalus and it’s extraction for its chemical composition class, and provide the basis for further research quality.

BACKGROUND/OBJECTIVES: The association between tea consumption and risk of coronary heart disease (CHD) remains controversial. This study aimed to determine whether tea consumption has an effect on CHD risk in Chinese adults. SUBJECTS/METHODS: In this hospital-based case-control study, 267 cases of CHD and 235 non-CHD controls were enrolled. Blood samples from all cases were examined. Cardiac function indices (left ventricular ejection fraction, left ventricular end-diastolic dimension, lactate dehydrogenase, and creatine kinase of the muscle or brain type), blood lipid index (high-density lipoprotein cholesterol), and blood coagulation function indices (fibrinogen and activated partial thromboplastin time) were recorded. Tea consumption of study participants was assessed by a specifically designed questionnaire. The baseline characteristics of the study populations were recorded, and CHD-related biomarkers were detected. Differences in baseline characteristics of the study participants were examined using t-tests for continuous variables and chi-squared tests for categorical variables. Unconditional logistic regression was used to measure the association between tea and CHD. RESULTS: There were significant differences in cardiac function indices, blood lipid index, and blood coagulation indices between CHD cases and controls (P < 0.05). We found tea consumption reduced CHD risk in female participants (adjusted odds ratio (OR) = 0.484, 95% CI: 0.242–0.968, P = 0.0403). Regarding the type of tea consumed, the risk of CHD was reduced in women who drank partially fermented tea (adjusted OR = 0.210, 95% CI: 0.084–0.522, P = 0.0008). Analytic results for the amount of tea consumed per unit time showed CHD risk was reduced in women who consumed 1–2 cups of tea per day (adjusted OR = 0.291, 95% CI: 0.131–0.643, P = 0.0023). A tea-drinking frequency of > 6 days/week was beneficial for CHD prevention (adjusted OR = 0.183, 95% CI: 0.049–0.679, P = 0.0112). When analyzed according to the duration of tea consumption, the risk of CHD was reduced in participants who had been drinking tea for 10–20 years (adjusted OR = 0.360, 95% CI: 0.137–0.946, P = 0.0382). CONCLUSIONS: Tea consumption is associated with a reduced risk of CHD in female but not male populations in Guangzhou.

Background/Aims: Alcohol represents a leading burden of disease worldwide, including alcohol use disorder (AUD) and alcohol-related liver disease (ALD). We aim to assess the global burden of AUD, ALD, and alcohol-attributable primary liver cancer between 2000–2021. Methods: We registered the global and regional trends of AUD, ALD, and alcohol-related liver cancer using data from the Global Burden of Disease 2021 Study, the largest and most up-to-date global epidemiology database. We estimated the annual percent change (APC) and its 95% confidence interval (CI) to assess changes in age-standardized rates over time. Results: In 2021, there were 111.12 million cases of AUD, 3.02 million cases of ALD, and 132,030 cases of alcohol-attributable primary liver cancer. Between 2000 and 2021, there was a 14.66% increase in AUD, a 38.68% increase in ALD, and a 94.12% increase in alcohol-attributable primary liver cancer prevalence. While the age-standardized prevalence rate for liver cancer from alcohol increased (APC 0.59%; 95% confidence interval [CI] 0.52 to 0.67%) over these years, it decreased for ALD (APC –0.71%; 95% CI –0.75 to –0.67%) and AUD (APC –0.90%; 95% CI –0.94 to –0.86%). There was significant variation by region, socioeconomic development level, and sex. During the last years (2019–2021), the prevalence, incidence, and death of ALD increased to a greater extent in females. Conclusions Given the high burden of AUD, ALD, and alcohol-attributable primary liver cancer, urgent measures are needed to prevent them at both global and national levels.

Objective: To analyze the blood pressure changes of adults aged 18-59 years in rural area of Shanxi province based on a cohort study, and provide reference for the study of the blood pressure level of rural residents and hypertension prevention and control in rural areas in China. Methods: Data were obtained from Shanxi Nutrition and Chronic Disease Family Cohort from 2002 to 2015. Subjects aged <18 years or ≥60 years and individuals with hypertension at baseline survey in 2002, and those who had taken antihypertensive drugs for nearly two weeks during the follow-up survey in 2015 were excluded from the study. A total of 1 629 subjects aged 18-59 years were included in the analyses of the blood pressure level and its change from the baseline survey in 2002 to follow-up survey in 2015. Results: The systolic blood pressure (SBP) of the subjects increased from (122.7±10.4) mmHg in 2002 to (132.8±17.6) mmHg in 2015 and the diastolic pressure (DBP) increased from (72.7±6.9) mmHg in 2002 to (78.8±10.3) mmHg in 2015. The SBP in men and women increased with growth rates of 6.7% and 9.5%. While DBP in men and women increased with growth rates of 9.3% and 7.8%. The SBP levels of those aged 18-, 30-, 40- and 50-59 years increased with growth rates of 5.0%, 6.7%, 9.4% and 11.8%. While the DBP of these age groups increased with growth rates of 12.2%, 8.2%, 8.2% and 6.5%. Conclusions The blood pressure of adults aged 18-59 years old in rural area of Shanxi showed a substantially increasing trend. The mean increase level of SBP in women was higher than that in men, and increased with age. While the mean increase level of DBP in men is higher than that in women, and decreased with age.

Objective: To explore the association between dietary pattern which benefit for normal kidney function and the risk of cognitive decline or impairment in the elderly. Methods: In 2015, subjects aged 60 and over from four counties in the Nutrition and Chronic Disease Family Cohort project, were followed up in 2017. Cognitive function was repeatedly assessed, using the Mini Mental State Evaluation (MMSE) scale. Dietary pattern that benefit for normal kidney function was extracted, using the reduced rank regression method and followed by logistic regression models to explore the associations between scores that showing the kidney function on dietary patterns and the risk of cognitive deterioration and impairment in two years among those who were with normal cognition in 2015. Results: Dietary pattern that benefit for normal kidney function, was characterized by high consumption of cereal, vegetables, legume and fruits but with less meat and soy products. Comparing with the group with lowest score quartile on this dietary pattern, the risk of cognitive deterioration in the highest quartile group was significantly low (P<0.01) in two years, with an odds ratio as 0.57 (95%CI: 0.37-0.85). Linear trend was also obviously visible (P=0.007) in this group. The ones at the highest quartile group among the normal cognition ones in 2015, the risk of cognitive impairment also significantly reduced (P<0.05) in two years time, with an odds ratio as 0.52 (95%CI: 0.29-0.93). Also, linear trend could obviously be seen (P=0.01). Conclusion Dietary pattern that benefit for normal kidney function was both inversely associated with cognitive deterioration and impairment, in two years.
