ObjectiveTo construct a nomogram prediction model for non-valvular persistent atrial fibrillation (PeAF) patients with left ventricular hypertrophy (LVH) , followed by prognostic analysis through follow-up. MethodsThis study retrospectively enrolled 949 patients with newly diagnosed and hospitalized non-valvular PeAF. Among them, 403 patients presented with LVH. The cohort was randomly stratified into a training set (n=665) and a validation set (n=284). Univariate and multivariate Logistic regression analyses were employed to identify independent risk factors for PeAF complicated by LVH. A nomogram prediction model was subsequently constructed and evaluated for discriminative ability, calibration, and clinical utility using receiver operating characteristic (ROC) curve analysis, calibration plots, and decision curve analysis (DCA). ResultsSeven independent risk factors were ultimately identified and included in the prediction model: female sex, hypertension, diabetes, red blood cell distribution width-SD (RDW-SD), body mass index (BMI), left atrial diameter (LAD), and left ventricular ejection fraction (LVEF). The area under the ROC curve (AUC) in the training set was 0.862 (95% CI: 0.834-0.890), and in the validation set, it was 0.870 (95% CI: 0.829-0.911), demonstrating excellent predictive performance. ConclusionIndependent risk factors for LVH in PeAF patients include female, hypertension, diabetes, RDW-SD, BMI, LAD, and LVEF. The prediction model built based on this can help early identification of PeAF patients with high risk of LVH. At the same time, the incidence of major adverse cardiovascular events (MACE) is higher in PeAF patients with LVH. Patients with atrial fibrillation combined with LVH may benefit from catheter ablation.

Da Chaihutang, first recorded in Shanghanlun by Zhang Zhongjing of the Eastern Han dynasty, is composed of eight medicinal herbs, namely Bupleuri Radix, Scutellariae Radix, Rhei Radix et Rhizoma, Aurantii Fructus Immaturus, Paeoniae Radix Alba, Pinelliae Rhizoma, Zingiberis Rhizoma Recens, and Jujubae Fructus. It features a well-defined hierarchy of sovereign, minister, assistant, and courier ingredients. The prescription is characterized by its balanced compatibility, mutually restrained cold and warm properties, and combined use of harmonizing and purging therapeutic strategies. As a renowned classical formula indicated for harmonizing Shaoyang and purging internal heat accumulation, it is the core prescription for the treatment of Shaoyang-Yangming combined disease. A comprehensive review of modern research literature on Da Chaihutang reveals that its chemical composition is notably diverse. The core pharmacologically active material bases of its constituent single herbs have been clearly identified, including saikosaponins from Bupleuri Radix, flavonoids from Scutellariae Radix, anthraquinones from Rhei Radix et Rhizoma, flavonoids and alkaloids from Aurantii Fructus Immaturus, monoterpene glycosides from Paeoniae Radix Alba, alkaloids and organic acids from Pinelliae Rhizoma, gingerols from Zingiberis Rhizoma Recens, and polysaccharides and triterpenoid acids from Jujubae Fructus. In the compound formula, a total of 163 chemical constituents have been comprehensively identified, among which flavonoids and their glycosides constitute the most abundant component category. Flavonoids and their glycosides, monoterpene glycosides, and pentacyclic triterpenoid saponins are regarded as the core pharmacologically active substances of the whole formula. In addition, 9 potential quality markers that can comprehensively characterize the overall quality and core therapeutic efficacy of the whole formula have been screened out. Modern pharmacological studies have shown that the pharmacological effects of Da Chaihutang exhibit synergistic characteristics involving multiple components, multiple targets, and multiple pathways. Its core pharmacological activities encompass the regulation of digestive system disorders, including pancreatic protection, intervention in biliary tract diseases, and protection of gastrointestinal mucosa; intervention in hepatobiliary diseases such as non-alcoholic fatty liver disease and cholestatic liver injury; and regulation of metabolic disorders such as hypoglycemic effect, improvement of insulin resistance, and regulation of lipid metabolism. Furthermore, it also possesses multiple pharmacological activities, including intervention in atherosclerosis, regulation of immune and inflammatory responses, multi-organ protection, and anti-hepatocellular carcinoma effect. In modern clinical practice, Da Chaihutang and its modified formulas are mostly used in combination with conventional Western medical regimens. They have demonstrated notable therapeutic advantages in the treatment of digestive system diseases such as cholecystitis, acute pancreatitis, cholelithiasis, and non-alcoholic fatty liver disease, but also have shown definite curative efficacy in the management of diseases affecting multiple other systems, including cardiovascular, endocrine, dermatological, reproductive, respiratory, neurological, urinary, pediatric, and immune systems. These combined applications can effectively improve the overall clinical response rate, shorten the time to symptom relief, and reduce both the disease recurrence rate and the incidence of adverse reactions. This review systematically summarized the formula compatibility, chemical constituents, pharmacological mechanisms, and modern clinical applications of Da Chaihutang and its modified formulas, to provide a theoretical basis and practical reference for the secondary development of classic formulas, the research and development of new drugs, and the precise and safe clinical application of this classical prescription.

Objective:This study aims to investigate the relationship between plague epidemics and environmental factors in Lincang City.Methods:Epidemiological survey data and environmental factors (including altitude, temperature, rainfall, and season) from plague occurrence sites in Lincang City from 1990 to 2020 were collected from Lincang Center for Disease Control and Prevention and the data sharing platform of the data sharing service network of the China Meteorological Administration, and analyzed using multiple correspondence analysis (MCA).Results:From 1990 to 2005, a total of 38 outbreaks of plague among rodents had been reported, 17 of which involved human beings. Since 2006, the plague had entered a dormant period, with no further epidemics reported up to 2020. The plague epidemic in Lincang City exhibited a clear seasonal variation, with the primary epidemic season occurred from autumn to early winter, peaking in September and October. Furthermore, the plague epidemic in Lincang City exhibited a pronounced spatial aggregation, with the primary affected regions including Linxiang County, Gengma Dai and Va Autonomous County, Zhenkang County, and Yun County. MCA showed that the Cronbach' α coefficients of all variables in the first and second dimensions were 0.87 and 0.82, respectively, and the characteristic roots were 3.27 and 2.91, respectively. The cumulative contribution rate of the two dimensions was 84.60%. Plague outbreaks were more likely in winter in areas at altitudes of > 1 400 - 1 650 m with 1 000 - 1 200 mm average annual rainfall and 16.0 - 17.9 ℃ average annual temperature, with increased severity. Regions at altitudes of > 500 - 700 m and > 900 - 1 150 m, with average annual rainfall of < 1 000, 1 201 - 1 400 and > 1 600 mm and average annual temperature of 18.0 - 19.9 ℃, showed a higher susceptibility to plague outbreaks, with notably pronounced incidences.Conclusions:The prevalence of plague epidemics is closely related to the local climatic conditions of natural foci in Lincang City. Therefore, it is imperative to enhance the monitoring of these climatic conditions, particularly meteorological data, to facilitate more effective prevention and control of plague outbreaks.

Objective:To investigate dietary patterns under social jet lag in pregnant women with gestational diabetes mellitus (GDM) and analyze its relationship with blood glucose control and delivery outcomes, to provide a reference for comprehensive management of pregnant women with GDM.Methods:A cross-sectional study method was used to select pregnant women with GDM during their stay in the obstetrics ward of the Obstetrics and Gynaecology Hospital of Nanjing Medical University from October 2022 to December 2023 as the study population. Social jet lag and dietary information were collected using Simplified Food Frequency Questionnaire and Self-assessment Questionnaire on Social Jet Lag. Spearman correlation analysis was used to analyze the correlation between dietary patterns and blood glucose control as well as delivery outcomes. Receiver operating characteristic curve was used to analyze the predictive performance of social jet lag, dietary patterns and fasting blood glucose for cesarean section.Results:A total of 350 pregnant women with GDM were included, 140 pregnant women with social time lag, aged (31.97 ± 3.88) years old; 210 pregnant women without social time lag, aged (32.32 ± 3.91) years old. The plant-based dietary pattern factor, fast food dietary pattern factor, and the intakes of protein, fat, and carbohydrates of pregnant women with social jet lag were -0.06 (-0.25, 0.32) and 0.08 (-0.43, 0.66), (119.57 ± 89.77) g, (82.69 ± 59.48) g, (228.77 ± 140.18) g, compared with pregnant women without social jet lag [-0.21 (-0.39, 0.08), -0.24 (-0.57, 0.07), (86.29 ± 47.75) g, (57.31 ± 37.86) g, (170.79 ± 85.56) g], the differences were statistically significant ( Z=-2.39, -2.86, t=81.43, 90.78, 88.34, all P<0.05). The social jet lag of GDM women was positively correlated with plant-based dietary patterns, fast food dietary patterns, fasting blood glucose, glycated hemoglobin and cesarean section ( r values were 0.19-0.24, all P<0.05). The plant-based dietary pattern of pregnant women with GDM was negatively correlated with fasting blood glucose and cesarean section ( r=-0.17, -0.24, both P<0.05), while the fast food dietary pattern was positively correlated with fasting blood glucose and cesarean section ( r=0.20, 0.19, both P<0.05). The area under the curve in the combined prediction of multiple factors such as social jet lag, plant-based dietary pattern, fast food dietary pattern and fasting blood glucose for the outcome of cesarean section during pregnancy was 0.742. Conclusions:The dietary structure of GDM women with social jet lag is unreasonable, consume more carbohydrates, sugar, and fats, which are associated with poor glycemic control and increased cesarean section rate. Medical staff should be alerted to social jet lag preferences and dietary intake of GDM and include them in the risk assessment of adverse outcomes of GDM, give timely correction and strengthen management, which can provide a reference for early preventive interventions for GDM with different risk stratification.

OBJECTIVE To investigate the protective effects of hydroxytyrosol hydroxybutyrate(HTHB)against cognitive impairment induced by acute sleep deprivation in mice and to explore the underlying mechanisms.METHODS Male C57BL/6J mice were assigned to the following groups:normal control,normal groups administered with HTHB 30,60 and 120 mg·kg-1 or hydroxytyrosol(HT 19.25,38.5 and 77 mg·kg-1),a sleep deprivation(SD)model group,and SD groups co-administered with the same doses of HTHB or HT.Acute sleep deprivation was induced for 72-96 h using a rotarod apparatus in all groups except the normal control and normal drug-treated groups.Based on dose-response assess-ments in the Y-maze and novel object recognition tests,the effective doses(HTHB 60 mg·kg-1 and HT 38.5 mg·kg-1)were selected for subsequent evaluation in the two-choice visual discrimination task that was performed in a subset of groups:normal control,normal+HTHB 60 mg·kg-1,normal+HT 38.5 mg·kg1,SD model,SD+HTHB 60 mg·kg-1,and SD+HT 38.5 mg·kg-1.Cognitive functions that were assessed included spatial working memory(Y-maze spontaneous alternation),object recognition memory(novel object recognition)and visual discrimination ability(two-choice visual discrimination task).Biochemically,levels of hippocampal reactive oxygen species(ROS)were quantified by ELISA while the ATP content was determined using a firefly luciferase-based assay.RESULTS In non-sleep-deprived mice,neither HTHB nor HT administration significantly altered locomotor activity,spatial working memory,object recognition memory,or visual discrimination performance.Following sleep deprivation,the model group displayed significant cognitive deficits,including reduced spontaneous alternation rate,lower novel object recognition indexes,and decreased accuracy in the visual discrimination task at 48 and 96 h.These impairments were accompanied by elevated hippocampal ROS levels and reduced ATP contents com-pared to the control group.Treatment with HT 38.5 and 77 mg·kg-1 significantly attenuated the deficit in spontaneous alternation,but did not affect other parameters.In contrast,HTHB at 60 and 120 mg·kg-1 produced broader restorative effects and significantly reversed impairment in both spontaneous alterna-tion and novel object recognition.Furthermore,HTHB at 60 mg·kg-1 significantly improved visual discrimination accuracy at 48 and 96 h,while lowering hippocampal ROS levels and increasing ATP contents.CONCLUSION HTHB effectively mitigates acute sleep deprivation-induced impairment in spatial working memory,object recognition memory,and visual discrimination in mice.This protection is likely mediated by the enhancement of mitochondrial antioxidant capacity and the restoration of energy metabolism.
