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.

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.

Objective To explore the mechanism of the intestinal barrier damage caused by Blastocystis hominis infections in rats. Methods Thirty SD rats were randomly divided into the control group, and the 1-, 3-, 6- and 9-week-infection groups, of 6 rats in each group. Rats in each infection group were orally infected with B. hominis trophozoites at a density of 2 × 108 parasites per rat, and the control group was given an equal volume of phosphate buffered saline solution. The 7-hour urine samples were collected 1, 3, 6 and 9 weeks post-infection for the measurement of the intestinal permeability. Then, rats were sacrificed using the cervical dislocation method, and the cecum specimens were collected for the detection of the intestinal epithelial cell permeability. The expression of tight junction-related Occludin and Claudin - 1 genes and apoptosis-related Bcl - 2 and Bax genes was quantified in cecum epithelial cells using the real-time fluorescent quantitative PCR (qPCR) assay, and cell apoptosis was detected in the rat cecum using the TdT-mediated dUTP nick-end labeling (TUNEL) assay. Results The median urinary lactolose to mannitol ratios were 0.29, 0.72, 0.44, 0.46 and 0.38 in the control group, and the 1-, 3-, 6- and 9-week-infection groups, respectively, and the difference was statistically significant (H = 12.09, P < 0.05). B. hominis invasion and epithelial injury were observed in intestinal epithelial cells of rats infected with B. hominis, and transmission electron microscopy displayed the destruction of tight junctions between intestinal epithelial cells. The relative expression of Occludin, Claudin-1, Bcl-2 and Bax genes was 1.04, 0.62, 0.71, 0.68 and 0.96; 1.03, 0.61, 0.63, 0.76 and 0.86; 1.08, 0.70, 0.75, 0.74 and 1.03; and 1.00, 1.57, 1.33, 1.35 and 1.10 in the control group and the 1-, 3-, 6- and 9-week-infection groups, respectively, and all differences were statistically significant (F = 2.86, 2.85, 3.37 and 4.45, all P values < 0.05). The median number of positive staining cells were 1.00, 13.00, 9.00, 3.50 and 1.00 in rat cecum specimens in the control group, and the 1-, 3-, 6- and 9-week-infection groups, respectively, and the difference was statistically significant (H = 22.95, P < 0.01). Conclusion B. hominis infection may cause an increase in the rat intestinal permeability through triggering the apoptosis of intestinal epithelial cells to destroy the tight junction between intestinal epithelial cells, thereby destroying the intestinal barrier function.

Objective:To observe the therapeutical effect and the safety of Pinggan Yuyin Qingre recipe on the hyperevaporative dry eye disease (Yin deficiency and Yang hyperactivity type) caused by the meibomian gland dysfunction(MGD). Method:The 120 Consecutive outpatients who met the criteria were included in the trial and divided into three layers (mild, moderate and severe) according to the meibomian gland function classification (grade 1-3). The patients in each layer were randomly assigned to the experiment group and the control group at a ratio of 1∶1. Both groups were treated with sodium hyaluronate eye drops, 1 drop/eye/time, 3 times a day. In the experiment group, Pinggan Yuyin Qingre recipe was additionally prescribed two times a day. The treatment course was 8 weeks in both groups. All patients were evaluated at the beginning and end of the study mainly for noninvasive tear breakup time (NITBUT),corneal lesions score,meibomian gland exclusion score,meibomian gland structure,eye symptom score,the ocular surface disease index(OSDI) score,and the traditional Chinese medicine(TCM) syndrome scores at both overall and layered levels. Result:A total of 116 cases completed the study,with 1 drop-out case and 3 eliminated cases. Both before and after treatment,NITBUT,the corneal lesions score,the symptom score,and the OSDI score in the experiment group were significantly superior to the control group, but there was no significant difference in meibomian gland exclusion score between two groups,only with a superior tendency in experiment group. There were significant differences in the scores of the related TCM syndrome scores between two groups after treatment. There were no adverse reactions, no abnormal changes in electro cardiogram (ECG) or liver and kidney functions in all patients. Conclusion:Pinggan Yuyin Qingre recipe can effectively improve the hyperevaporative dry eye disease caused by meibomian gland dysfunction, the tear film stability,eye dryness, burning,itching,foreign body sensation and TCM symptoms of patients with dry eye syndrome of Yin deficiency and Yang hyperactivity. The improvement effect is more obvious in moderate and severe patients. It is an effective,safe,and well-tolerated treatment for the hyperevaporative dry eye.
