This study aims to explore whether Naoxintong Capsules improve multiple cerebral infarctions and myocardial injury via promoting angiogenesis, thereby exerting a simultaneous treatment effect on both the brain and heart. Male SD rats were randomly divided into six groups: sham-operated group, model group, high-dose, medium-dose, and low-dose groups of Naoxintong Capsules(440, 220, and 110 mg·kg~(-1)), and nimodipine group(10.8 mg·kg~(-1)). Rat models of multiple cerebral infarctions were established by injecting autologous thrombus, and samples were collected and tested seven days after modeling. Evaluations included multiple cerebral infarction model assessments, neurological function scores, grip strength tests, and rotarod tests, so as to evaluate neuromotor functions. Morphological structures of brain and heart tissue were observed using hematoxylin-eosin(HE) staining, Nissl staining, and Masson staining. Network pharmacology was employed to screen the mechanisms of Naoxintong Capsules in improving multiple cerebral infarctions and myocardial injury. Neuronal and myocardial cell ultrastructures were observed using transmission electron microscopy. Apoptosis rate in brain neuronal cells was detected by TdT-mediated dUTP nick end labeling(TUNEL) staining, and reactive oxygen species(ROS) levels in myocardial cells were measured. Immunofluorescence was used to detect the expression of platelet endothelial cell adhesion molecule-1(CD31), antigen identified by monoclonal antibody Ki67(Ki67), hematopoietic progenitor cell antigen CD34(CD34), and hypoxia inducible factor-1α(HIF-1α) in brain and myocardial tissue. Western blot, and real-time quantitative polymerase chain reaction(RT-qPCR) were used to detect the expression of HIF-1α, vascular endothelial growth factor(VEGF), vascular endothelial growth factor receptor 2(VEGFR2), sarcoma(Src), basic fibroblast growth factor(bFGF), angiopoietin-1(Ang-1), and TEK receptor tyrosine kinase(Tie-2). Compared with the model group, the medium-dose group of Naoxintong Capsules showed significantly lower neurological function scores, increased grip strength, and prolonged time on the rotarod. Pathological damage in brain and heart tissue was reduced, with increased and more orderly arranged mitochondria in neurons and cardiomyocytes. Apoptosis in brain neuronal cells was decreased, and ROS levels in cardiomyocytes were reduced. The microvascular density and endothelial cells of new blood vessels in brain and heart tissue increased, with increased overlapping regions of CD31 and Ki67 expression. The relative protein and mRNA expression levels of HIF-1α, VEGF, VEGFR2, Src, Ang-1, Tie-2, and bFGF were elevated in brain tissue and myocardial tissue. Naoxintong Capsules may improve multiple cerebral infarctions and myocardial injury by mediating HIF-1α/VEGF expression to promote angiogenesis.

High-performance liquid chromatography(HPLC) was used to determine the content of three major components in Citri Reticulatae Semen(CRS), including limonin, nomilin, and obacunone. The chromaticity of the CRS sample during salt processing and stir-frying was measured using a color difference meter. Next, the relationship between the color and content of the salt-processed CRS sample was investigated through correlation analysis. By integrating the oil bath technique for processing simulation with HPLC, the changes in the relative content of nomilin and its transformation products were analyzed, with its structural transformation pattern during processing identified. Additionally, RAW264.7 cells were induced with lipopolysaccharides(LPSs) to establish an inflammatory model, and the anti-inflammatory activity of nomilin and its transformation product, namely obacunone was evaluated. The results indicated that as processing progressed, E~*ab and L~* values showed a downward trend; a~* values exhibited a slow increase over a certain period, followed by no significant changes, and b~* values remained stable with no significant changes over a certain period and then started to decrease. The limonin content remained barely unchanged; the nomilin content decreased, and the obacunone increased significantly. The changing trends in content and color parameters during salt-processing and stir-frying were basically consistent. The content of nomilin and obacunone was significantly correlated with the colorimetric values(L~*, a~*, b~*, and E~*ab), while limonin content showed no significant correlation with these values. By analyzing HPLC patterns of nomylin at different heating temperatures and time, it was found that under conditions of 200-250 ℃ for heating of 5-60 min, the content of nomilin significantly decreased, while the obacunone content increased pronouncedly. The in vitro anti-inflammatory activity results indicated that compared to the model group, the group with a high concentration of nomilin and the groups with varying concentrations of obacunone showed significantly reduced release of nitric oxide(NO)(P<0.01). When both were at the same concentration, obacunone showed better performance in inhibiting NO release. In this study, the obvious correlation between the color and content of major components during the processing of CRS samples was identified, and the dynamic patterns of quality change in CRS samples during processing were revealed. Additionally, the study revealed and confirmed the transformation of nomilin into obacunone during processing, with the in vitro anti-inflammatory activity of obacunone significantly greater than that of nomilin. These findings provided a scientific basis for CRS processing optimization, tablet quality control, and its clinical application.

Objective: To describe the prevalence of alcohol consumption and the burden of hemorrhagic stroke and hypertensive heart disease attributed to alcohol consumption in adults aged ≥20 years in 31 provinces in China from 2005 to 2018. Methods: Data from several national representative surveys was used to estimate provincial alcohol exposure level of adults aged ≥20 years from 2005 to 2018 by using kriging interpolation and locally weighted regression methods. Global disease burden research method and data, and China's death cause surveillance data were used to calculate the population attributable fraction (PAF) of hemorrhagic stroke and hypertensive heart disease and the deaths due to alcohol consumption in men and women aged ≥20 years in 31 provinces in China. China census data of 2010 were used to calculate the attributable standardized mortality rate. Results: In 2005 and 2018, the prevalence of alcohol consumption was 58.7% (95%CI: 57.8%-59.5%) and 58.4% (95%CI: 57.6%-59.3%), respectively, in men and 17.0% (95%CI: 16.6%-17.4%) and 18.7% (95%CI:18.1%-19.3%), respectively, in women. The daily alcohol intake was 24.6 (95%CI: 23.8-25.3) g and 27.7 (95%CI: 26.8-28.7) g, respectively, in men and 6.3 (95%CI: 6.0-6.5) g and 5.3 (95%CI: 5.0-5.6) g, respectively, in women. Alcohol exposure level was higher in the provinces in central and eastern China than in western provinces. The lowest exposure level was found in northwestern provinces. From 2005 to 2018, the PAF of hemorrhagic stroke death due to alcohol consumption increased from 5.5% to 6.8%, the attributable deaths increased from 50 200 to 59 100, while the PAF of hypertensive heart disease death due to alcohol consumption increased from 7.0% to 7.7%, the attributable deaths increased from 15 200 to 29 300. The PAF of hypertensive heart disease and hemorrhagic stroke was higher in men than in women, and in central and eastern provinces than in western provinces. In 2018, the standardized mortality rates of hemorrhagic stroke and hypertensive heart disease attributed to alcohol consumption were 4.58/100 000 and 2.11/100 000, respectively. Conclusions: The prevalence of alcohol consumption in men and daily alcohol intake of drinkers were relatively high in China, especially in eastern provinces. Alcohol exposure level was lower in women than in men. Regional measures should be taken to reduce the alcohol intakes in men and current drinkers in order to reduce the health problems caused by alcohol consumption.

Objective: To estimate the risk for type 2 diabetes mellitus (T2DM) death attributed to insufficient whole grain intake in seven regions of China from 2005 to 2018. Methods: Based on China National Nutrition and Health Surveys and China Adult Chronic Disease and Nutrition Surveillance, ordinary Kriging method and locally weighted regression were used to estimate the level of whole grain intake of Chinese residents from 2005 to 2018. Based on the results of the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 and Chronic Diseases Risk Factors Surveillance in China, we calculated the population attributable fraction (PAF), attributable death number and attributable mortality rate of T2DM due to insufficient whole grain intake in people aged ≥20 years in different regions of China, and we used the 2010 Chinese census data to compare the changes in T2DM deaths attributed to insufficient intake of whole grains in seven regions of China. Results: The whole grain intake levels of Chinese people over 20 years old in 2002, 2010 and 2015 were 19.0 g/d, 14.3 g/d and 19.8 g/d, respectively. The estimated overall whole grain intake level was 20.1 g/d in Chinese residents in 2018, and the intake level was 19.4 g/d in men and 20.8 g/d in women. Among the seven regions, the intake level was highest in northern China (47.4 g/d) and lowest in southwestern China (6.0 g/d). In 2018, the PAF was lowest in northern China (12.8%) and highest in southwestern China (19.3%). From 2005 to 2018, the PAF varied in the seven regions, and the PAF in northeastern China fluctuated around 18.5%. Other regions showed downward trends, especially in northern China and northwestern China, decreased by 26.4% and 21.2%, respectively. Over the past 14 years, the number of attributable deaths in the seven regions showed upward trends, with the highest annual average growth rate of 6.7% in southern China and the lowest annual average growth rate of 2.4% in northern China. In 2018, the standardized T2DM mortality rate attributed to insufficient whole grain intake in China was 3.13/100 000, and the attributable mortality was 3.21/100 000 in men and 3.05/100 000 in women. The standardized attributable mortality rate was highest in southwestern China (3.97/100 000) and lowest in northern China (1.78/100 000). From 2005 to 2018, the standardized attributable mortality rate increased by 11.5% in men and decreased by 8.1% in women. The standardized attributable mortality rate in southwestern, southern and central China increased by 23.7%, 21.3% and 4.2%, respectively. The standardized attributable mortality rate in northern, northwestern, eastern and northeastern China decreased by 20.9%, 11.0%, 4.5% and 3.9%, respectively. Conclusion: The whole grain intake level of Chinese residents was low, and the whole grain intake of residents in all seven regions should be increased, especially in the southwest, and men should have more whole grain intake than women to reduce the death risk in patients with T2DM.

Aim To investigate the effects and possible molecular mechanisms of dioscin(DIO)against depression in mice.Methods Eighty mice were randomly divided into control group, DIO control group, model group, DIO groups(20, 40 and 80 mg·kg-1 DIO)and FLU group(20 mg·kg-1 fluoxetine).After establishing the depression model with chronic unpredictable moderate stress(CUMS)in mice, the corresponding drugs were administered by gavage continuously for four weeks in each group.The behavior of mice was tested, and the contents of corticosterone(CORT), brain-derived neurotrophic factor(BDNF), 5-hydroxytryptamine(5-HT), malondialdehyde(MDA), superoxide dismutase(SOD)and catalase(CAT)were evaluated by ELISA or enzyme labeling method.In addition, HE staining, Nissl staining and PET scanning were operated for the brain tissues.Western blot was used to detect the protein expressions.Results Compared with model group, DIO significantly improved the behaviors of depressed mice.And it reduced the contents of CORT in serum, increased BDNF and 5-HT in hippocampus.Meanwhile, DIO obviously reduced MDA in serum, increased SOD in serum and CAT in brain tissues.DIO improved the steatosis of brain tissues, disorder and looseness of neurons, and increased glucose metabolism in brain tissues of depressed mice.The molecular mechanism suggested that compared with model group, DIO significantly increased the protein level of UCP2 to adjust the levels of Nrf2, SOD2, GLUT1 and G6Pase.Conclusions DIO improves the depression symptoms of depressed mice, which should be through adjusting UCP2-mediated oxidative stress and glucose metabolism.

Objective: This study aims to investigate the sleep quality of pregnant women in Xuhui District, Shanghai, and the related factors of sleep disturbances during pregnancy. Methods: From February 2019 to February 2021, we used online integrated sleep questionnaire (including PSQI, BQ, ESS, AIS) in Shanghai Jiao Tong University School of Medicine Affiliated Sixth People's Hospital, The International Peace Maternity and Child Health Hospitals of China Welfare Institution, and Shanghai Eighth People's Hospital, to investigate the sleep quality across pregnancy. We also collected maternal physical examination results, childbearing history, sociodemographic, and other clinical data. The prevalences and related factors of various sleep disturbances in pregnant women were analyzed, including insufficient/excessive nighttime sleep, low sleep efficiency, difficulty falling asleep, poor sleep quality, insomnia, daytime sleepiness, and high risk of sleep-disordered breathing (SDB). Results: This study includes 1 898 cases in the first trimester (T1), 3 099 cases in the second trimester (T2), and 1 539 cases in the third trimester (T3). Poor sleep quality (38.6%), daytime sleepiness (mild 41.9%, moderate 17.7%, severe 2.1%), and suspicious insomnia (32.3%) are most prevalent among women in T1 (P<0.01). In comparison, short sleep time (2.7%), long sleep time (8.6%), difficulty falling asleep (12.2%), poor sleep efficiency (35.4%), very poor sleep quality (6.7%), clinical insomnia (21.8%), and high-risk SDB (6.4%) are most prevalent among women in T3 (P<0.05). During pregnancy, late gestation (OR=1.016, 95%CI: 1.006-1.025) and multiple induced/drug abortions (OR=1.329, 95%CI: 1.043-1.692) are risk factors for poor sleep quality (PSQI>5), while multiple full-term deliveries (OR=0.800, 95%CI: 0.675-0.949) is its protective factor. Advanced maternal age (OR=0.976, 95%CI: 0.956-0.997), multiple full-term deliveries (OR=0.808, 95%CI: 0.680-0.959), late gestation (OR=0.983, 95%CI: 0.974-0.992) and hypertension (OR=0.572, 95%CI: 0.401-0.814) are protective factors for daytime sleepiness (ESS>6). The high-risk pregnancy category (OR=9.312, 95%CI: 1.156-74.978) is a risk factor for insomnia (AIS≥4), while multiple full-term deliveries (OR=0.815, 95%CI: 0.691-0.961) is its protective factor. High BMI (OR=1.334, 95%CI: 1.270-1.402) and hypertension (OR=4.427, 95%CI: 2.539-7.719) are risk factors for high-risk SDB in pregnant women. Conclusions: The prevalences of various sleep disturbances are high throughout pregnancy. Noticeably, symptoms of maternal SDB develop along with pregnancy. Different types of sleep disturbances are associated with different factors. Women of high-risk pregnancy category, in late gestation, with high BMI, hypertension, a history of induced/drug abortion, or without a history of full-term delivery can be at high risk of sleep disturbances during pregnancy.

ObjectiveTo explore the effect and mechanism of Xiaojindan extract （XJD） on macrophage polarization. MethodLipopolysaccharide （LPS） and interleukin-4 （IL-4） were used to induce M1 and M2 polarization of RAW264.7 cells. The influence of 10-80 mg·L^-1 XJD on cell proliferation was detected by Cell Counting Kit-8 （CCK-8） assay. Nitric oxide （NO） and interleukin-6 （IL-6） release was explored by Griess assay and enzyme-linked immunosorbent assay （ELISA）， respectively. The mRNA expression of M1 and M2 macrophage markers was measured by real-time quantitative polymerase chain reaction （Real-time PCR）， and the CD206⁺ expression was determined by flow cytometry. The activation of phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） pathway was analyzed by western blot. Result10-80 mg·L^-1 XJD showed no marked cytotoxicity in LPS （0.5 mg·L^-1）- or IL-4 （20 μg·L^-1）-induced RAW264.7 cells. Compared with the control group， LPS significantly promoted the expression of M1 macrophage markers （P<0.01）， including increased NO and IL-6 release （P<0.01） and upregulated mRNA expression of interleukin-1β （IL-1β）， inducible nitric oxide synthase （iNOS）， cyclooxygenase-2 （COX-2） and tumor necrosis factor-α （TNF-α） （P<0.01）. Compared with LPS-induced group， 20-80 mg·L^-1 XJD decreased the release of NO and IL-6 in a dose-dependent manner （P<0.01）， and similarly 10-80 mg·L^-1 XJD suppressed the mRNA expression of IL-1β， iNOS， COX-2 and TNF-α （P<0.01）. Compared with the control group， IL-4 obviously increased the expression of M2 macrophage markers （P<0.01）， including increased CD206⁺ cell population and upregulated mRNA expression of arginine-1 （Arg-1）， interleukin-10 （IL-10）， interleukin-13 （IL-13） and transforming growth factor-β₁ （TGF-β₁）. Compared with IL-4-induced group， 10-80 mg·L^-1 XJD dose-dependently decreased CD206⁺ cell population （P<0.01） and inhibited the mRNA expression of Arg-1， IL-10， IL-13 and TGF-β₁ （P<0.01）. Western blot showed that XJD significantly downregulated the activation of PI3K/Akt pathway as compared to LPS- and IL-4-induced groups （P<0.05， P<0.01）. ConclusionXJD significantly inhibited the macrophage polarization in the LPS- and IL-4-induced RAW264.7 cells by targeting PI3K/Akt pathway.

Objective:To investigate the relationship between electrocardiographic (ECG) changes and prognosis of paraquat poisoning patients, so as to provide evidence for the condition assessment in paraquat poisoning patients.Methods:In January 2022, The clinical data of paraquat poisoning patients were retrospectively analyzed in the First Affiliated Hospital of Wenzhou Medical University from January 1, 2016 to December 31, 2021. The patients' basic information (age, sex, underlying disease, and occupation) and the ECG within 24 hours were collected, and the data were statistically analyzed by SPSS 22.0. One variable analysis and multivariable logistic regression analysis were used to analyze the risk factors related to prognosis determine in their ECG. The receiver operating characteristic (ROC) curve were used to evaluate the diagnostic value of ECG indexes in patients with paraquat poisoning.Results:A total of 145 patients with paraquat poisoning were finally enrolled in this study, there were 84 patients survived and 60 patients died. One variable analysis revealed that heart rate ( P=0.000) , QTc changes ( P=0.000) , and ST-T changes ( P=0.007) of ECG had statistically significant differences in the prognosis of paraquat poisoning patients between the survival group and the death group. Multifactorial logistic results showed that heart rate ( OR=1.059, 95% CI: 1.033~1.086) and QTc ( OR=1.015, 95% CI: 1.000~1.029) were independent risk factors for death diagnosis of patients with paraquat poisoning ( P<0.05) . ROC curve analysis revealed that the area under the cure (AUC) of the prediction model constructed based on heart rate and QTc was 0.832 (95% CI: 0.765~0.899) , with the best diagnostic efficacy. Conclusion:Heart rate, QTc and the prediction model constructed based on both can be used as prognostic indicators for the diagnosis of patients with paraquat poisoning, and which have reference value for clinical prognosis diagnosis.
