Pan vascular disease （PVD） is a systemic vascular disorder that has become the leading cause of death among the Chinese residents， and there is currently a lack of effective systemic treatment options. Clinical practice has found that the traditional Chinese medicine （TCM） method of kidney tonification can effectively intervene in PVD and target key pathological mechanisms of PVD recognized in Western medicine. Accordingly， this paper conducts research from the following three aspects： First， it clarifies that immune dysregulation， metabolic disorders， and genetic susceptibility constitute the core pathological mechanisms of PVD in Western medicine. Typical pathological manifestations include progressive vascular endothelial injury， lipid deposition， and plaque formation， ultimately leading to multi-organ damage and dysfunction. PVD activates pathways such as the NOD-like receptor thermal protein domain-associated protein 3 （NLRP3） inflammasome， triggering immune dysregulation； it also induces disorders of mitochondrial energy metabolism， water-salt metabolism， and hormonal metabolism， synergizing with genetic susceptibility factors （e.g.， apolipoprotein E gene） to accelerate vascular homeostasis imbalance. Second， this study analyzes the intrinsic relationship between the TCM theory of "kidney deficiency" and the "immune-metabolic-genetic" axis， revealing the theoretical basis for kidney tonification in intervening PVD. The kidney stores essence， governs bones， and produces marrow， which is related to the generation and differentiation of immune cells. It regulates Qi transformation and governs water， overseeing material and energy metabolism. The kidney is the root of congenital essence and governs reproduction， closely related to genetic mechanisms. Third， by integrating modern clinical research， this study elaborates on the unique advantages and clinical value of kidney tonification in targeting the "immune-metabolic-genetic" axis of heart， brain， and kidney organs. Traditional kidney-tonifying formulas and their active ingredients improve immune-inflammatory responses， enhance material and energy metabolism homeostasis， and modulate epigenetic pathways through multiple pathways， targeting various pathways to intervene in PVD. This study systematically elucidates the scientific connotation of kidney tonification in treating PVD， providing theoretical support and practical guidance for integrated TCM-Western medicine approaches and contributing to innovation and improvement in diagnostic and treatment strategies for PVD.

Panvascular diseases represent systemic vascular disorders characterized by atherosclerosis as their core pathological feature. Their incidence rates continue to rise， posing significant challenges for clinical management. Based on Traditional Chinese Medicine （TCM） theory of ''positive deficiency phlegm stasis''， this study delved into the pivotal role of mitochondrial homeostasis dysregulation in the pathogenesis and progression of pan-vascular diseases， along with its intrinsic connection to TCM pathogenesis. Mitochondrial homeostasis dysregulation pervades the entire course of these diseases， with mitochondrial oxidative stress serving as the initiating factor. Excessive reactive oxygen species （ROS） trigger endothelial dysfunction， lipid accumulation， and inflammatory initiation. Additionally， the imbalance between mitochondrial autophagy and apoptosis constitutes a pivotal link in disease progression. Excessive or insufficient autophagy may lead to the accumulation of damaged mitochondria and excessive cellular apoptosis， thereby promoting plaque instability. Furthermore， mitochondrial metabolic reprogramming impairs energy supply and function in vascular wall cells， hindering subsequent vascular repair. These pathological processes constitute the microscopic manifestation of the core pathogenesis， which is characterized by ''the intermingle of phlegm and stasis and the deficiency of healthy Qi''. Specifically， the endogenous phlegm-turbidity drives mitochondrial oxidative stress injuries， the mutual entanglement of phlegm and stasis induces an imbalance between mitochondrial autophagy and apoptosis， while deficiency of healthy Qi propels mitochondrial energy metabolism disorders and reprogramming. In view of this， this study proposed to employ phlegm-resolving and turbidity-clearing methods to mitigate mitochondrial oxidative stress injuries， phlegm-resolving and blood-activating methods to regulate mitochondrial autophagy and apoptosis， and spleen-tonifying and kidney-nourishing methods to modulate mitochondrial metabolic reprogramming. This approach can prevent and treat panvascular diseases by multi-target regulation of mitochondrial homeostasis， providing a theoretical framework and therapeutic strategies for the prevention and treatment of panvascular diseases through integrated Chinese and Western medicine.

Objective To analyze the risk factors of plastic bronchitis (PB) in children with severe mycoplasma pneumoniae pneumonia (SMPP) and construct a Nomogram model. Methods A total of 195 children with SMPP from April 2022 to April 2025 were selected and divided into the PB group and the non-PB group according to the occurrence of PB. Their clinical data were compared. Binary logistic regression was used to analyze the risk factors of PB in SMPP, and ROC was used to analyze the predictive ability of the model. The Nomogram prediction model was established using R-4.4.3 software, and the calibration curve and clinical decision curve were plotted for analysis. Results PB occurred in 66 cases (33.85%) (P < 0.05). The duration of fever, PIV, SII, D-D, LDH, and pleural effusion were independent risk factors for PB in SMPP (OR=6.997, 1.016, 1.008, 70.202, 1.025, 32.323, P < 0.05). Based on this, the PB prediction model for SMPP occurrence established had a good goodness of fit (P > 0.05), and the area under the ROC curve was 0.888 (95%CI : 0.878-0.898). The average absolute error of Bootstrap repeated sampling 1000 times was 0.021, and the model C-index was 0.889 (95%CI: 0.888-0.991). The predicted probability of the model has a good consistency with the actual probability, with good accuracy, and the Brier score is 0.035 (95%CI: 0.015-0.054). Good clinical benefits can be achieved when the threshold probability is between 0.01 and 0.99. Conclusion The Nomogram model of PB in children with SMPP constructed based on factors such as fever duration, PIV, SII, D-D, LDH, and pleural effusion has good discrimination and accuracy, and can provide a reference for the prevention of PB.

Objective:To investigate the diversity, temporal dynamics and influencing factors of serotypes of Salmonella among asymptomatic workers in Yulin, Guangxi Zhuang Autonomous Region, from 2013 to 2023, and provide reference for controlling the hidden transmission of Salmonella and for disease prevention among healthy populations. Methods:Anal rectal swabs were collected from asymptomatic workers in Yulin from 2013 to 2023 for the isolation and identification of Salmonella. The diversity of serotypes of Salmonella was evaluated by using Shannon index, while the isolation rates and composition ratio of different serotypes were compared with χ2 test. Spearman correlation analysis was used to evaluate the correlation of natural and social factors with serotype isolation rates for more than eight years, and stepwise multiple linear regression analysis were used to evaluate the impact of social factors on the serotype isolation rates for more than 8 years. Results:A total of 8 073 strains of Salmonella were isolated from 2013 to 2023, with an overall isolation rate of 18.88‰ During the 11-year period, 135 serotypes of Salmonella were identified, and the serotype diversity increased first and then decreased. The serotype with the highest isolation rate was Salmonella Typhimurium (3.04‰), followed by Salmonella Rissen (1.70‰), Salmonella Corvallis (1.41‰), Salmonella Agona (1.36‰), Salmonella Derby (1.22‰), and Salmonella London (1.02‰), accounting for 51.67% of the total Salmonella serotypes isolated. There was no significant trend in isolation rate of Salmonella over the years ( χ2=0.67, P=0.415); however, season significantly influenced the isolation rate, with lower rate being observed in winter and higher rate in summer ( χ2=615.91, P<0.001). The isolation rate of different serotypes of Salmonella was influenced by social and natural factors, showing a positive correlation with temperature, precipitation, and poultry consumption and production levels. Conclusions:The serotypes of Salmonella carried by asymptomatic workers were complex and diverse in Yulin, Guangxi Zhuang Autonomous Region, from 2013 to 2023, and the isolation rates of multi-serotypes increased from 2013 to 2023. Higher isolation rate was observed in summer and the isolation rate was widely influenced by natural factors such as temperature and precipitation, as well as social factors such as economic conditions. It is necessary to pay attention to the Salmonella serotype carriage in healthy population, and strengthen monitoring of both healthy individuals and pathogenic bacteria.
