ObjectiveTo investigate the ameliorative effect of Wendantang combined with Danshenyin and Dushentang (WDD) on mice with ischemic heart disease (IHD) presenting phlegm-stasis syndrome based on the inflammatory phenotype and differentiation of circulating monocytes. MethodsA model of IHD with phlegm-stasis syndrome was established using left anterior descending coronary artery ligation supplemented with a high-fat diet. Eighty model mice were randomly assigned to the model group, WDD low-dose group (WDD-L), WDD medium-dose group (WDD-M), WDD high-dose group (WDD-H), and atorvastatin calcium tablet group, with 16 mice in each group. An additional 16 C57BL/6J mice were designated as the sham-operation group. The WDD groups received intragastric administration at doses of 8.91, 17.81, 35.62 g·kg-1, and the atorvastatin calcium tablet group received the corresponding drug at 1.3 mg·kg-1, twice daily. The sham-operation and model groups were given the same volume of pure water by gavage each day. After 5 consecutive weeks of administration, the cardiac index was calculated. Cardiac function was assessed by echocardiography. Myocardial histopathology was examined by hematoxylin-eosin (HE) staining. Serum N-terminal pro-B-type natriuretic peptide (pro-BNP) content was measured by enzyme-linked immunosorbent assay (ELISA). Hemorheological parameters were analyzed using an automated hemorheology analyzer. Serum levels of total cholesterol (TC), triglycerides (TG), low-density lipoprotein (LDL), and high-density lipoprotein (HDL) were determined using an automated biochemical analyzer. Changes in circulating monocytes were detected by flow cytometry. Mouse bone marrow mononuclear cells were isolated in vitro and divided into blank group, model serum group, WDD-L drug-containing serum group, WDD-M drug-containing serum group, and WDD-H drug-containing serum group. CD36 expression and macrophage differentiation in each group were assessed by flow cytometry. The mechanism by which WDD mediates circulating monocyte differentiation was further explored using CD36 knockdown/overexpression RAW264.7 cell lines. ResultsCompared with the sham-operation group, the model group showed a significantly increased cardiac index (P0.01), significantly decreased fractional shortening (FS) (P0.01), and significantly increased left ventricular end-diastolic internal diameter (LVDD) and left ventricular end-systolic internal diameter (LVDS) (P0.01). Cardiomyocytes exhibited marked deformation and necrosis with inflammatory cell infiltration. Serum pro-BNP levels were significantly elevated (P0.01), and whole-blood viscosity (BV) at high, medium, and low shear rates was significantly increased (P0.01). Compared with the model group, the WDD groups showed significantly reduced cardiac index (P0.05, P0.01), significantly increased FS (P0.05, P0.01), significantly decreased LVDD and LVDS (P0.01), markedly improved cardiomyocyte morphology, significantly reduced inflammatory infiltration, significantly decreased serum pro-BNP levels (P0.01), and significantly decreased BV at high, medium, and low shear rates (P0.01), with the most pronounced improvement observed in the WDD-M group. Compared with the sham-operation group, TC, TG, and LDL levels were significantly increased in the model group (P0.05, P0.01), while HDL levels were significantly decreased (P0.05). After WDD-H treatment, TC, TG, and LDL levels were significantly reduced and HDL levels were significantly increased in mice (P0.05, P0.01). Compared with the sham-operation group, classical monocytes in blood and bone marrow and intermediate monocytes in blood were significantly increased in the model group (P0.01), whereas intermediate monocytes in bone marrow and non-classical monocytes in blood were significantly decreased (P0.01). After WDD administration, all circulating monocyte subsets in blood and bone marrow were significantly alleviated (P0.05, P0.01), with the WDD-M group showing the optimal effect. In vitro, compared with the blank group, CD36 expression on bone marrow monocytes and the proportion of differentiated macrophages were significantly increased in the model serum group (P0.01), and CD36 expression was significantly upregulated on RAW264.7 cells (P0.01). Compared with the model serum group, all drug-containing serum groups exhibited significantly reduced CD36 expression on bone marrow monocytes and significantly reduced macrophage differentiation (P0.01). WDD downregulated CD36 expression in both CD36 knockdown and overexpression RAW264.7 cell lines (P0.05, P0.01), with the strongest regulatory effect observed in the WDD-M drug-containing serum group. ConclusionWDD can significantly improve the manifestations of phlegm-stasis syndrome in IHD mice and reduce the proportion of classical circulating monocytes. Its mechanism may be related to the inhibition of CD36 expression on classical circulating monocytes.

Chronic obstructive pulmonary disease (COPD) is a chronic respiratory disease that poses a significant threat to global health, exhibiting high morbidity, disability and mortality rate, with its prevention and treatment situation becoming increasingly critical. The pathogenesis of COPD is complex, and the underlying cellular and molecular biological mechanisms remain incompletely elucidated. Programmed cell death (PCD) is the process wherein cells actively undergo demise to maintain internal environmental stability in response to certain signals or specific stimuli. Contemporary medical research indicates that the dysregulation of PCD patterns such as apoptosis, necroptosis, pyroptosis, autophagy, and ferroptosis is closely related to the onset and progression of COPD. Clarifying the molecular mechanisms of PCD in COPD may provide novel perspectives for in-depth understanding and prevention of the disease. Traditional Chinese medicine (TCM) is characterized by holistic regulation. In recent years, extensive research has been conducted in the TCM field focusing on modulating apoptosis, necroptosis, pyroptosis, autophagy, and ferroptosis for the treatment of COPD, yielding remarkable achievements. Therefore, this study systematically explored the molecular mechanism of PCD in COPD and reviewed the potential mechanisms and intervention status of TCM targeting PCD in COPD, aiming to provide insights and references for the clinical prevention, treatment and in-depth research of COPD.

Based on spleen deficiency-phlegm dampness as the core pathogenesis of obesity, and integrating recent advances in modern medicine regarding the key role of immune inflammation in obesity, this paper proposes a multidimensional pathogenic network of "obesity-spleen deficiency-phlegm dampness-immune imbalance". Various traditional Chinese medicine (TCM) herbs that strengthen the spleen, regulate qi, and resolve phlegm and dampness can treat obesity by improving spleen-stomach transport and transformation, promoting water-damp metabolism, and regulating immune homeostasis. This highlights immune inflammation as an important entry point to elucidate the TCM concepts of "spleen deficiency-phlegm dampness" and the therapeutic principle of "strengthening the spleen and eliminating dampness to treat obesity". By systematically analyzing the intrinsic connection between "spleen deficiency generating dampness, internal accumulation of phlegm dampness" and immune dysregulation in obesity, this paper aims to provide theoretical support for TCM treatment of obesity based on dampness.

ObjectiveTo observe the clinical effectiveness and safety of Qingfei Shenshi Decoction (清肺渗湿汤) combined with western medicine for patients with bronchial asthma of heat wheezing syndrome, and to explore its potential mechanism of action. MethodsEighty-six participants with bronchial asthma of heat wheezing syndrome were randomly divided into treatment group and control group, each group with 43 participants. The control group received conventional western medicine, and the treatment group was additionally administered Qingfei Shenshi Decoction orally on the basis of the control group, 1 dose per day. Both groups were treated for 14 days. The primary outcome measure was clinical effectiveness; secondary outcome measures included traditional Chinese medicine (TCM) syndrome score, asthma control test (ACT) score, pulmonary function indices such as forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), peak expiratory flow (PEF), serum inflammatory factor levels including interleukin-4 (IL-4), tumour necrosis factor-α (TNF-α), and high-sensitivity C-reactive protein (hs-CRP), and immune function indices including CD3+, CD4+, CD8+, CD4+/CD8+. All outcome measures were evaluated before and after treatment. Vital signs were monitored, and electrocardiography, blood routine, urine routine, liver function, and renal function tests were performed before and after treatment. Adverse events and reactions during the study were recorded. ResultsA total of 80 patients completed the trial with 40 in each group. The total clinical effective rate of the treatment group was 97.5% (39/40), which was significantly higher than that of the control group (85.0%, 34/40, P<0.05). After treatment, both groups showed decreased TCM syndrome scores, IL-4, TNF-α, hs-CRP, and CD8+ levels, as well as increased ACT scores, CD3+, CD4+, CD4+/CD8+, FEV1, FVC, and PEF levels (P<0.05 or P<0.01). Moreover, the improvements in these indices were more significant in the treatment group than in the control group (P<0.05 or P<0.01). No significant abnormalities in safety indicators were observed in either group, and no adverse events or reactions occurred. ConclusionQingfei Shenshi Decoction combined with conventional western medicine for patients with bronchial asthma of heat wheezing syndrome can effectively improve the clinical symptoms, pulmonary function, and clinical effectiveness, with good safety. Its mechanism may be related to reducing inflammatory factor levels and regulating T lymphocyte subsets to improve immune function.

Objective:To investigate the clinical characteristics of omphalocele, and to assess the risk factors associated with adverse outcomes.Methods:A retrospective cohort study was conducted. Clinical data of 224 patients diagnosed with omphalocele, who were hospitalized at Children′s Hospital, Zhejiang University School of Medicine from January 2013 to December 2022, were collected. Based on their discharge outcomes, the patients were classified into 2 groups: favorable outcomes and unfavorable outcomes. Chi-square test or continuity correction χ2 test or Fisher exact probability method, and Mann-Whitney U test were used for intergroup comparisons. Logistic regression analysis was performed to identify risk factors associated with adverse outcomes in omphalocele. Results:Among the 224 patients with omphalocele, 126 were male. A total of 208 patients (92.9%) had favorable outcomes, while 16 patients (7.1%) had unfavorable outcomes. In the unfavorable outcomes group, 14 patients had giant omphaloceles, while 100 patients had giant omphaloceles in the favorable outcomes group. The rates of herniation of more than two intra-abdominal organs in the hernial sac, congenital heart defects, patent ductus arteriosus, pulmonary hypertension, sepsis and infection of the hernial sac, were all higher in the unfavorable outcomes group compared to the favorable outcomes group (all P<0.05). Patients with unfavorable outcomes had longer mechanical ventilation time, duration of oxygen use, duration of parenteral nutrition, hospital stays, and higher rates of parenteral nutrition-associated cholestasis compared to those with favorable outcomes (all P<0.01). Multivariate Logistic regression analysis indicated that pulmonary hypertension ( OR=9.39, 95% CI 1.20-73.32), sepsis ( OR=8.59, 95% CI 1.32-55.86), and congenital heart defects ( OR=6.55, 95% CI 1.11-38.73) were all independent risk factors for adverse outcomes in omphalocele (all P<0.05). Conclusions:Infants with omphalocele are prone to complications such as cardiovascular malformations, infections, and pulmonary hypertension. Adverse outcomes in omphalocele are associated with pulmonary hypertension, sepsis, and congenital heart defects.

OBJECTIVE To investigate the protective effect and mechanism of saikosaponin C (SSC) on acute liver injury (ALI) in mice induced by carbon tetrachloride (CCl4) based on serum metabolomics. METHODS Forty mice were divided into blank group (water), model group (water), positive control drug group (Biphenyl diester drop pills, 150 mg/kg), and SSC low- and high-dose groups (2.5, 10 mg/kg) using the random number table method, with 8 mice in each group. They were given water/ relevant drugs, once a day, for 7 consecutive days. One hour after the last administration, all mice were intraperitoneally injected with 0.2% CCl4 olive oil to induce ALI model, except for the blank group. After 17 hours of the modeling, the liver index of mice was calculated. The levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and IL-1β in serum of mice were detected. The histopathological changes of liver tissue were observed. Meanwhile, the serum metabolomics of mice were analyzed by liquid chromatography-mass spectrometry. RESULTS Compared with the blank group, the levels of liver index, ALT, AST, LDH, TNF-α, IL-6, and IL-1β in the model group were significantly increased (P<0.01). Hepatocytes were edema, vacuolar degeneration, more necrosis, and a large number of inflammatory cells were infiltrated. Compared with the model group, liver index and serum index levels of mice were significantly decreased (P<0.05 or P<0.01), accompanied by marked improvement in histopathological damage to the liver tissue. The metabolomics results showed that compared with the model group, there were 63 up-regulated and 256 down-regulated differential metabolites in the serum of mice in the SSC high-dose group, including prostaglandin B2, 20-hydroxy-leukotriene B4, 5- hydroxy-L-tryptophan, 7α -hydroxycholesterol, etc.; these metabolites were primarily involved in metabolic pathways such as arachidonic acid metabolism, 5-hydroxytryptamine synapse, primary bile acid biosynthesis. CONCLUSIONS SSC exerts a protective effect against CCl4-induced ALI by down-regulating the level of key metabolites such as prostaglandin B2 and 20-hydroxy-leukotriene B4, and then ruducing metabolic pathways such as arachidonic acid metabolism, 5- hydroxytryptamine synapse, and primary bile acid biosynthesis.

ObjectiveBy exploring the influencing factors of readmission in patients with stable angina of coronary heart disease (CHD) based on real-world clinical data, to establish a risk prediction model of integrated traditional Chinese and western medicine, in order to provide a basis for early identification of high-risk populations and reducing readmission rates. MethodsA prospective clinical study was conducted involving patients with stable angina pectoris of CHD, who were divided into a training set and a validation set at a 7∶3 ratio. General information, traditional Chinese medicine (TCM)-related data, and laboratory test results were uniformly collected. After a one-year follow-up, patients were classified into a readmission group and a non-readmission group based on whether they were readmitted. Univariate and multivariate logistic regression analyses were performed to identify independent risk factors for readmission. A risk prediction model of integrated traditional Chinese and western medicine was constructed and visualized using a nomogram. The model was validated and evaluated in terms of discrimination, calibration, and clinical decision curve analysis. ResultsA total of 682 patients were included, with 477 in the training set and 205 in the validation set, among whom 89 patients were readmitted. Multivariate logistic regression analysis identified heart failure history [OR = 6.93, 95% CI (1.58, 30.45)], wiry pulse [OR = 2.58, 95% CI (1.42, 4.72)], weak pulse [OR = 3.97, 95% CI (2.06, 7.67)], teeth-marked tongue [OR = 4.38, 95% CI (2.32, 8.27)], blood stasis constitution [OR = 2.17, 95% CI (1.06, 4.44)], phlegm-stasis mutual syndrome [OR = 3.64, 95% CI (1.87, 7.09)], and elevated non-high-density lipoprotein cholesterol [OR = 1.30, 95% CI (1.01, 1.69)] as influencing factors of readmission. These factors were used as predictors to construct a nomogram-based risk prediction model for readmission in patients with stable angina. The model demonstrated moderate predictive capability, with an area under the receiver operating characteristic curve (AUC) of 0.818 [95% CI (0.781, 0.852)] in the training set and 0.816 [95% CI (0.779, 0.850)] in the validation set. The Hosmer-Lemeshow test showed good calibration (χ² = 4.55, P = 0.80), and the model's predictive ability was stable. When the threshold probability exceeded 5%, the clinical net benefit of using the model to predict readmission risk was significantly higher than intervening in all patients. ConclusionHistory of heart failure, teeth-marked tongue, weak pulse, wiry pulse, phlegm-stasis mutual syndrome, blood stasis constitution, and non-high-density lipoprotein cholesterol are influencing factors for readmission in patients with stable angina of CHD. A clinical prediction model was developed based on these factors, which showed good discrimination, calibration, and clinical utility, providing a scientific basis for predicting readmission events in patients with stable angina.

Objective To analyze the influencing factors of malaria infection of labor service exported to overseas in Langfang City, in order to establish a visualization tool to assist clinicians in predicting the risk of malaria. Methods A total of 4 774 expatriate employees of the Nibei Pipeline Project of the Pipeline Bureau from October 2021 to August 2023 were taken as the subjects, and the gender, age, overseas residence area and Knowledge of malaria controlscores of the study subjects were investigated by questionnaire survey, and the possible risk factors of malaria were screened by logistic regression model. At the same time, the nomogram prediction model was established, and the subjects were divided into the training group and the validation group at a ratio of 2:1, and the area under the curve (ROC) and the decision curve were plotted to evaluate the prediction ability and practicability of the prediction model in this study. Results Among the 4 774 study subjects, 96 cases of malaria occurred, and the detection rate was 2.01%. Junior school (OR=1.723,95% CI:1.361-2.173), and residence in rural areas(OR=2.091,95%CI:1.760 -3.100)were risk factors (OR>1), while protective measures(OR=0.826,95% CI : 0.781 - 0.901) and high malaria education scores (OR=0.872,95% CI : 0.621 - 0.899)were protective factors.The nomogram prediction model results showed that the area under the curve of the nomogram prediction model in the training group was 0.94 (95% CI : 0.85 - 1.00), while the validation group was 0.93 (95% CI : 0.80 - 1.00). The results of the decision curve showed that when the threshold probability of the population was 0-0.9, the nomogram model was used to predict the risk of malaria occurrence with the highest net income. Conclusion The nomogram prediction model (including gender, education, region, protection and malaria education score) established and validated in this study is of great value for clinicians to screen high-risk patients with malaria.
