ObjectiveTo explore the feasibility, evaluation methods and metabolic differences of high-fat diet(HFD) combined with myocardial ischemia-reperfusion injury(MIRI) to establish a rat model of myocardial ischemia-reperfusion with phlegm and blood stasis blocking collaterals syndrome(PBSBCS). MethodsThirty-two SD rats were randomly divided into the sham operation, HFD, MIRI, and MIRI+HFD groups. Rats in the sham operation and MIRI groups were fed a standard diet(regular chow), while the HFD and MIRI+HFD groups received a HFD for 10 weeks. Rats in the MIRI and MIRI+HFD groups underwent myocardial ischemia-reperfusion surgery, while the sham operation group underwent only thread placement without ligation. Cardiac function was assessed via small-animal echocardiography, including left ventricular ejection fraction(EF), left ventricular fractional shortening(FS), cardiac output(CO), and stroke volume(SV). Serum levels of creatine kinase(CK), CK-MB, triglyceride(TG), total cholesterol(TC), high-density lipoprotein cholesterol(HDL-C), low-density lipoprotein cholesterol(LDL-C), lactate dehydrogenase(LDH), endothelin-1(ET-1), endothelial nitric oxide synthase(eNOS), tumor necrosis factor-α(TNF-α), interleukin-18(IL-18), oxidized LDL(ox-LDL), and cardiac troponin T(cTnT) were measured by biochemical assays and enzyme-linked immunosorbent assay(ELISA). Myocardial histopathology was evaluated via hematoxylin-eosin(HE) staining, while myocardial infarction and no-reflow area were assessed using 2,3,5-triphenyltetrazolium chloride(TTC), Evans blue, and thioflavin staining. Changes in syndrome characteristics[body weight, tongue surface red-green-blue [RGB] values, and pulse amplitude] of PBSBCS were recorded. Serum differential metabolites were analyzed by ultra-high performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS). ResultsCompared with the sham operation group, the HFD and MIRI+HFD groups showed significant increases in body weight(P<0.01), RGB values and pulse amplitude decreased in the HFD, MIRI and MIRI+HFD groups, TC, TG, LDL-C and ox-LDL levels increased in the HFD and MIRI+HFD groups, while HDL-C decreased. Blood perfusion peak time and myocardial no-reflow area increased, serum eNOS level decreased, and CK-MB, LDH, and cTnT activities increased in the HFD, MIRI and MIRI+HFD groups(P<0.05, P<0.01). Whole blood viscosity was increased in the HFD group at medium shear rate, and in the MIRI and MIRI+HFD groups at low, medium and high shear rates(P<0.05, P<0.01). Platelet aggregation rate increased in the MIRI and MIRI+HFD groups, accompanied by elevated ET-1, TNF-α, and IL-18 levels, reduced cardiac function indices, expanded myocardial no-reflow and infarction areas, and increased serum CK, CK-MB, LDH, and cTnT activities(P<0.05, P<0.01). Compared with the MIRI group, the HFD and MIRI+HFD groups showed significant increase in body weight, TC, TG, LDL-C and ox-LDL levels, and significant decrease in HDL-C content(P<0.01). The MIRI+HFD group showed decrease in RGB values and pulse amplitude, and an increase in whole blood viscosity, platelet aggregation, blood perfusion peak time, myocardial no-reflow and infarction areas, elevated ET-1, TNF-α and IL-18 levels, decreased eNOS content, EF and SV, increased serum CK, CK-MB and cTnT activities, and worsened myocardial pathology(P<0.05). Compared with the HFD group, the MIRI+HFD group showed similar aggravated trends(P<0.05, P<0.01). Metabolomics results showed that 34 potential biomarkers involving 13 common metabolic pathways were identified in the MIRI+HFD group compared with the sham operation group. ConclusionThe MIRI group resembles blood stasis syndrome in hemodynamics and myocardial injury, and the HFD group mirrors phlegm-turbidity syndrome in lipid profiles and tongue characteristics. While the MIRI+HFD group aligns with PBSBCS in comprehensive indices, effectively simulating clinical features of coronary heart disease(CHD), which can be used for the evaluation of the pathological mechanism and pharmacodynamics of CHD with PBSBCS.

With the continuous advancement of internet technology and the improvement of internet literacy among the general population, the concept of online-offline integration in internet hospitals has gradually gained acceptance and has been applied and developed both domestically and internationally. In thoracic surgery, the applicability of this model lies in enhancing efficiency and delivering comprehensive, diversified, and personalized medical services to address complex and severe conditions. However, challenges such as hardware limitations and diagnostic/treatment risks persist during the implementation of internet hospitals. Through future in-depth and localized research, the online-offline integration of internet hospitals is expected to undergo further development and refinement. This progress will facilitate its integration into clinical practice in thoracic surgery, ultimately providing patients with improved medical care services.

OBJECTIVES:
To evaluate the clinical efficacy of hospital-prepared Chinese medicine Feigan granules for influenza patients. This study has been registered at the International Traditional Medicine Clinical Trial Registry platform (ITMCTR2025000162).
METHODS:
A prospective observational study was conducted on influenza patients who visited the Fever Clinic of the First Affiliated Hospital, Zhejiang University School of Medicine between February and March 2024. Patients were divided into the observation group (Feigan granules combined with conventional Western medicine) and the control group (conventional Western medicine). Main symptoms (including fever, cough and sore throat) and secondary symptoms (including chest tightness, poor appetite, muscle soreness and dry mouth) were evaluated with traditional Chinese medicine (TCM) symptom scale on the first day of the patient's visit and the third day after treatment. The degrees of improvement in the TCM symptom scores before and after treatment were compared using paired rank-sum test, and the differences in the overall symptom efficacy index between two groups were compared using the Wilcoxon test.
RESULTS:
A total of 217 influenza patients were included. After treatment, the TCM symptom scores of both groups were significantly improved compared with those before treatment (all P<0.01). The median differences in the main symptom score before and after treatment in the observation and the control groups were 7 points (95%CI: 6.0-8.0) and 6 points (95%CI: 6.0-8.0), respectively. The median difference in the secondary symptom score was 3 points (95%CI: 2.0-4.0) in both groups. The median differences in the total score were 9 points (95%CI: 8.0-10.5) and 8 points (95%CI: 7.0-10.0) in the observation and control groups, respectively. In the subgroup with an initial cough score >2, the improvement rates of total score (97.06% vs. 92.59%) and secondary symptoms (92.31% vs. 85.11%) in observation group were significantly higher than those in the control group (P<0.05); while there was no significant difference in the improvement rate of the main symptoms (95.59% vs. 90.74%, P>0.05).
CONCLUSIONS
Feigan granules can improve the TCM syndromes of influenza patients, especially for patients with more severe cough.

BACKGROUND:
The mechanisms distinguishing metabolically healthy from unhealthy phenotypes within the same BMI categories remain unclear. This study aimed to investigate the associations between regional fat distribution and metabolically unhealthy phenotypes in Chinese adults across different BMI categories.
METHODS:
This cross-sectional study involving 11833 Chinese adults aged 20 years and older. Covariance analysis, adjusted for age, compared the percentage of regional fat (trunk, leg, or arm fat divided by whole-body fat) between metabolically healthy and unhealthy participants. Trends in regional fat percentage with the number of metabolic abnormalities were assessed by the Jonckheere-Terpstra test. Odds ratios (ORs) and their 95% confidence intervals (CIs) were estimated by logistic regression models. All analyses were performed separately by sex.
RESULTS:
In non-obese individuals, metabolically unhealthy participants exhibited higher percent trunk fat and lower percent leg fat compared to healthy participants. Additionally, percent trunk fat increased and percent leg fat decreased with the number of metabolic abnormalities. After adjustment for demographic and lifestyle factors, as well as BMI, higher percent trunk fat was associated with increased odds of being metabolically unhealthy [highest vs. lowest quartile: ORs (95%CI) of 1.64 (1.35, 2.00) for men and 2.00 (1.63, 2.46) for women]. Conversely, compared with the lowest quartile, the ORs (95%CI) of metabolically unhealthy phenotype in the highest quartile for percent arm and leg fat were 0.64 (0.53, 0.78) and 0.60 (0.49, 0.74) for men, and 0.72 (0.56, 0.93) and 0.46 (0.36, 0.59) for women, respectively. Significant interactions between BMI and percentage of trunk and leg fat were observed in both sexes, with stronger associations found in individuals with normal weight and overweight.
CONCLUSIONS
Trunk fat is associated with a higher risk of metabolically unhealthy phenotype, while leg and arm fat are protective factors. Regional fat distribution assessments are crucial for identifying metabolically unhealthy phenotypes, particularly in non-obese individuals.

Acute lung injury (ALI) is a significant complication of sepsis, characterized by high morbidity, mortality, and poor prognosis. Neutrophils, as critical intrinsic immune cells in the lung, play a fundamental role in the development and progression of ALI. During ALI, neutrophils generate neutrophil extracellular traps (NETs), and excessive NETs can intensify inflammatory injury. Research indicates that Taohe Chengqi decoction (THCQD) can ameliorate sepsis-induced lung inflammation and modulate immune function. This study aimed to investigate the mechanisms by which THCQD improves ALI and its relationship with NETs in sepsis patients, seeking to provide novel perspectives and interventions for clinical treatment. The findings demonstrate that THCQD enhanced survival rates and reduced lung injury in the cecum ligation and puncture (CLP)-induced ALI mouse model. Furthermore, THCQD diminished neutrophil and macrophage infiltration, inflammatory responses, and the production of pro-inflammatory cytokines, including interleukin-1β (IL-1β), IL-6, and tumor necrosis factor α (TNF-α). Notably, subsequent experiments confirmed that THCQD inhibits NET formation both in vivo and in vitro. Moreover, THCQD significantly decreased the expression of peptidyl arginine deiminase 4 (PAD4) protein, and molecular docking predicted that certain active compounds in THCQD could bind tightly to PAD4. PAD4 overexpression partially reversed THCQD's inhibitory effects on PAD4. These findings strongly indicate that THCQD mitigates CLP-induced ALI by inhibiting PAD4-mediated NETs.

Chinese Journal of Lung Cancer 2024;27(2):133-137
As a new diagnosis and treatment decision-making model,shared decision making(SDM)can effective-ly solve the problem of patient compliance in the diagnosis and treatment of thoracic tumors,balance the status of both doctors and patients,and gradually get attention and application in the clinical practice of thoracic surgery.The application of SDM in the diagnosis and treatment of thoracic tumors is conducive to improve doctors'diagnosis and treatment level and alleviating the pressure of responsibility,reduce patients'psychological pressure and improve patients'compliance and also improve medi-cal trust and reduce doctor-patient conflict.Due to the limited medical literacy and autonomy of patients,the time for diagnosis and treatment is short due to the imbalance of doctor-patient ratio.Meanwhile,due to the limited sample size of existing stud-ies,SDM model cannot be proved to have a clear gain for the treatment of thoracic tumors,and the implementation of SDM model still faces resistance.In the future,the development of auxiliary decision-making system and the improvement of doc-tors'humanistic care ability will be conducive to promote the practical application of SDM model in thoracic surgery.

Thoracic surgery encompasses the diagnosis and treatment of various chest diseases such as lung cancer,esophageal cancer,and mediastinal tumors.The treatment plans for these diseases are complex and often involve a combina-tion of surgery,chemotherapy,and radiotherapy,each with different impacts on the patient's quality of life.Patient-reported outcomes(PRO)and shared decision-making(SDM)are becoming increasingly important in this field.PRO allows patients to directly report their health status and the effects of treatment,aiding doctors in adjusting treatment plans.SDM ensures that treatment plans align with the patient's personal values and preferences through information sharing and joint decision-making.The comprehensive application of PRO and SDM can enhance patient satisfaction and treatment outcomes,though it also faces challenges such as data collection and time management.Future research should focus on developing more efficient PRO tools and SDM processes to improve patient-centered healthcare quality.
