Objectives:The purpose of this cross-sectional study was to determine the predictive value of measuring awake blood pressure(BP)at different time points on nocturnal hypertension by ambulatory blood pressure monitoring(ABPM)device in patients with hypertension. Methods:A total of 204 consecutive hypertensive outpatients seeking medical care at the First Affiliated Hospital of Fujian Medical University from April 2023 to July 2023 were enrolled.We measured office BP and out-office BP.Out-office BP include evening BP,bedtime BP,morning BP and mean morning BP which were measured by ABPM device and BP daily record.Nocturnal hypertension was defined by the mean nocturnal systolic blood pressure≥120 mmHg(1 mmHg=0.133 kPa).ROC curve analyses of different awake blood pressure was established to identify significant correlates to nocturnal hypertension.The serial test was also performed.The value of the two indexes in predicting nocturnal hypertension was compared.The predictors of nocturnal hypertension were evaluated by multivariate analysis. Results:Of the 204 subjects,104(51.0%)had nocturnal hypertension.The repeated measures analysis of variance(ANOVA)showed that mean nighttime systolic BP and bedtime systolic BP were similar(P=0.641).Nocturnal hypertension was present in 75.7%(84/111)of patients with bedtime systolic BP≥120 mmHg,in 94.2%(49/52)of patients with bedtime systolic BP≥135 mmHg and in 88.2%(75/85)of patients with mean morning systolic BP≥135 mmHg.ROC curve analyses showed that the diagnostic accuracy of mean morning systolic BP(AUC 0.903,P<0.05)for subjects with nocturnal hypertension was significantly superior to that of office systolic BP,evening systolic BP,bedtime systolic BP,morning systolic BP.Multivariate logistic regression analysis revealed that mean morning systolic BP and bedtime systolic BP were significantly associated with a higher risk of nocturnal hypertension(P<0.05).ROC curve analyses of predicted probability of bedtime systolic BP and mean morning systolic BP showed higher diagnostic accuracy(AUC 0.929,P<0.05).The serial test showed that nocturnal hypertension was present in 98.0%(49/50)of patients with bedtime systolic BP≥130 mmHg and mean morning systolic BP≥135 mmHg. Conclusions:Mean morning BP and bedtime BP are significant correlates of nocturnal hypertension in patients with hypertension,and combined mean morning BP with bedtime BP showed higher diagnostic accuracy,which might used for predicting nocturnal hypertension with high efficiency.

Objective To investigate the effects of esketamine on hypoxic-ischemic myocardial injury in neonatal rats based on glycogen synthase kinase-3β/NOD-like receptor thermal protein domain-containing protein 3 (GSK-3β/NLRP3) pathway. Methods Thirty neonatal rats were randomly divided into sham operation group, model group and esketamine group, with 10 rats in each group. The rats in the sham operation group underwent a median incision in the neck to expose the bilateral common carotid arteries; the rats in the model group and the esketamine group underwent ligation of the common carotid arteries combined with a hypoxic environment to establish a model ofischemia and hypoxia; the rats in the esketamine group were given esketamine intervention (50 mg/kg). Left ventricular ejection fraction (LVEF), left ventricular fractional shortening (LVFS), left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD), serum creatine kinase isoenzyme (CK-MB), cardiac troponin I (cTnI), lactate dehydrogenase (LDH), tumor necrosis factor-α (TNF-α), interleukin (IL)-6 and IL-1β levels, myocardial injury, myocardial cell apoptosis and apoptosis protein caspase 1/3/9 levels, neutrophil infiltration in myocardial tissue, and changes in GSK-3β and NLRP3 protein levels in myocardial tissue were detected in each group. Results Compared with the sham operation group, the LVEF and LVFS were significantly decreased and the LVEDD and LVESD were significantly increased in the model group, while the LVEF and LVFS were significantly higher and the LVEDD and LVESD were significantly lower in the esketamine group than in the model group (

With the rapid development of information technology, research on ancient TCM books has shifted from the traditional collation and digitization into intelligent knowledge service, thereby achieving the deep integration of ancient TCM books collation and clinical needs. Based on the clinical problem and knowledge element theory, we implemented in-depth indexing and knowledge mining for 600 kinds of ancient TCM books, built a knowledge sharing service platform for ancient TCM books by integrating database, cloud platform, knowledge graph and other technologies, and carried out the thematic literature research and developed databases for four major diseases including stroke, heart failure, liver cirrhosis, and diabetes. The digital intelligence products have been applied in hundreds of hospitals for evaluation and feedback. Finally, through "digital processing plus intelligent application", the two-way interaction between ancient TCM books and current clinical practice is realized, and the path and paradigm of ancient TCM books knowledge serving the modern prevention and control of major diseases is formed, providing reference for the innovative utilization of ancient TCM books.

Objective:To understand the impact of diet on glycemic control in community-managed patients with type 2 diabetes mellitus (T2DM) and provide evidence for implementing prevention strategies and measures for diabetes patients.Methods:Eight communities were randomly selected from Changshu and Wuhan in 2015, and T2DM patients managed in the community were selected to conduct questionnaire surveys, physical measurements, and blood glucose testing. Factor analysis was used to obtain dietary patterns. A binary logistic regression model was used to analyze the factors affecting glycemic control.Results:Finally, 1 818 T2DM patients were included, and the control rate of FPG was 57.59% (95% CI: 55.30%-59.86%), and the control rate of 2 h postprandial blood glucose (2 h PBG) was 24.90% (95% CI: 22.93%- 26.91%). Five dietary patterns were obtained by factor analysis: animal food pattern, fruit-aquatic products-potato patterns, vegetable-grain pattern, egg-milk-bean pattern, and oil-salt patterns. No-conditional multivariate logistic regression analysis showed that after adjusting for confounding factors, the reduced probability of FPG control was related to animal food pattern ( OR=0.71, 95% CI: 0.52-0.98) and fruit-aquatic products-potato patterns ( OR=0.71, 95% CI: 0.51-0.97). The decrease in the 2 h PBG control probability was related to fruit-aquatic products-potato patterns ( OR=0.60, 95% CI: 0.40-0.90). The increased probability of FPG and 2 h postprandial glucose control were both related to vegetable-grain pattern ( OR=1.41, 95% CI: 1.03-1.94; OR=1.68, 95% CI: 1.13-2.51) and egg-milk-bean pattern ( OR=1.75, 95% CI: 1.25-2.46; OR=1.56, 95% CI: 1.00-2.42). Compared with the Q4 group of egg-milk-bean pattern, the FPG control rate of the combination of "fruit-aquatic products-potato pattern ( Q4 group), vegetable-grain pattern ( Q2 group), egg-milk-bean pattern ( Q3 group)" was higher ( OR=6.79, 95% CI: 1.15-40.23, P=0.035). Compared with the Q4 group of vegetable-grain pattern, the combination of "fruit-aquatic products-potato pattern ( Q4 group), vegetable-grain pattern ( Q3 group), egg-milk-bean pattern ( Q2 group), oil-salt pattern ( Q2 group)" had higher control rate of 2 h PBG ( OR=12.78, 95% CI: 1.26-130.05, P=0.031). Conclusions:A proper combination of dietary patterns and dietary patterns are more conducive to the control of FPG and 2 h PBG in T2DM patients managed in the communities of Wuhan and Changshu. Patient nutrition education should be strengthened, and the food-matching ability of patients should be improved.

Objective To compare the dosimetric characteristics of thyroid between intensity-modulated radiotherapy (IMRT) and volumetric modulated arc therapy (VMAT) in patients with left-sided breast cancer after modified radical mastectomy. Methods Thirty patients with left-sided breast cancer who underwent adjuvant radiotherapy after modified radical mastectomy at the Huangpu Branch of the Ninth People’s Hospital, Shanghai Jiao Tong University School of Medicine, from December 2021 to May 2023, were selected as the study subjects, and IMRT and VMAT were used with a target prescription dose of 50 Gy/25 times. The target dose parameters of the two plans, including the mean dose (Dmean) and the dose-volume limit for organs at risk (Vx, x represents dose), were compared. Results The conformity index of VMAT was higher than that of IMRT (P<0.001). Compared with VMAT, IMRT plan significantly reduced the V5、V10、Dmean of heart, the V5 of right lung and the Dmean of right breast, while it significantly increased the V20 of left lung (P<0.001). There was no statistically significant difference in V5 and V10 of the left thyroid between IMRT and VMAT. However, the V20, V30, V40, and Dmean of left and whole thyroid, and the V10 and Dmean of right thyroid were significantly lower in IMRT than those in VMAT (P<0.001). Conclusions Both IMRT and VMAT plans can meet the clinical dosimetric requirements, among which IMRT has lower thyroid exposure dose and is more suitable for patients with high cardiac requirements.

In atherosclerosis, chronic inflammatory processes in local diseased areas may lead to the accumulation of reactive oxygen species (ROS). In this study, we devised a highly sensitive H2O2-scavenging nano-bionic system loaded with probucol (RPP-PU), to treat atherosclerosis more effectively. The RPP material had high sensitivity to H2O2, and the response sensitivity could be reduced from 40 to 10 μmol/L which was close to the lowest concentration of H2O2 levels of the pathological environment. RPP-PU delayed the release and prolonged the duration of PU in vivo. In Apolipoprotein E deficient (ApoE‒/‒) mice, RPP-PU effectively eliminated pathological ROS, reduced the level of lipids and related metabolic enzymes, and significantly decreased the area of vascular plaques and fibers. Our study demonstrated that the H2O2-scavenging nano-bionic system could scavenge the abundant ROS in the atherosclerosis lesion, thereby reducing the oxidative stress for treating atherosclerosis and thus achieve the therapeutic goals with atherosclerosis more desirably.
