The lung collaterals form a network that branches from the lung meridian, traversing the lung system and extending across the body′s surface. Lung collateral disease refers to the structural alterations or dysfunction in these collaterals caused by external or internal pathogens. Research into the structural and physiological functions of children′s lung collaterals, as well as the pathogenesis and syndrome differentiation for treating lung collateral diseases in children, holds significant value in guiding the prevention and treatment of pediatric respiratory conditions. Drawing on the theory of collateral disease, the clinical insights of both historical and contemporary physicians, and modern research findings—while considering the unique physiological and pathological characteristics of children′s respiratory systems—this study provides a foundational summary of the morphology and spatial distribution of children′s lung collaterals. The characteristics of these collaterals are highlighted as thin, sparse, short, narrow, brittle, and tender. From this structural understanding, the unique physiological functions of children′s lung collaterals are analyzed. The study further explores the interactions between pathogenic factors and lung collaterals, elucidating the pathogenesis and progression of children′s lung collateral diseases. It proposes treatment principles centered on "seeking treatment in the collaterals and employing the method of unblocking collaterals, "which align with the unique features of pediatric lung collaterals. Common treatment approaches, and relevant prescriptions for managing these diseases are summarized. This paper lays the foundation for a theoretical system encompassing the structure, function, pathogenesis, and syndrome differentiation for treating children′s lung collateral diseases. It offers valuable insights for the clinical diagnosis and management of pediatric respiratory diseases linked to collateral dysfunction and serves as a reference for the systematic development of a broader theoretical framework for children′s collateral diseases.

Inflammatory bowel disease (IBD) is an idiopathic intestinal inflammatory condition with chronic and relapsing manifestations and is characterized by a disturbance in the interplay between the intestinal microbiota, the gut, and the brain. The microbiota-gut-brain axis involves interactions among the nervous system, the neuroendocrine system, the gut microbiota, and the host immune system. Increasing published data indicate that psychological stress exacerbates the severity of IBD due to its negative effects on the microbiota-gut-brain axis, including alterations in the stress response of the hypothalamic-pituitary-adrenal (HPA) axis, the balance between the sympathetic nervous system and vagus nerves, the homeostasis of the intestinal flora and metabolites, and normal intestinal immunity and permeability. Although the current evidence is insufficient, psychotropic agents, psychotherapies, and interventions targeting the microbiota-gut-brain axis show the potential to improve symptoms and quality of life in IBD patients. Therefore, further studies that translate recent findings into therapeutic approaches that improve both physical and psychological well-being are needed.

Objective:To evaluate the clinical value of combined detection of placenta associated 8 (PLAC8) and platelet activating factor acetylhydrolase (PLA2G7) for early identification of sepsis and non-infectious systemic inflammatory response syndrome (SIRS).Methods:A cross-sectional study was conducted. A total of 189 febrile patients suspected infection who were admitted to Huashan Hospital, Fudan University from October 2022 to April 2023 were included. Based on etiological, laboratory test results and clinical data, patients were classified as infection or non-infection, and further classified as sepsis or non-infectious SIRS according to diagnostic criteria. Real-time fluorescence polymerase chain reaction was used to detect the mRNA levels of PLAC8 and PLA2G7 in peripheral venous blood of patients. Hematology, inflammatory markers including C-reactive protein (CRP), interleukin-6 (IL-6) and procalcitonin, sepsis-related organ failure assessment (SOFA) score, and the difference of cycle threshold (Ct) values between PLA2G7 and PLAC8 ((PLA2G7-PLAC8)ΔCt value))were compared between the sepsis and non-infectious SIRS groups. Statistical comparison was analyzed using Mann-Whitney U test, and the diagnostic performance of (PLA2G7-PLAC8)ΔCt value in discriminating sepsis from non-infectious SIRS was evaluated using receiver operating characteristic curve. Results:Among the 189 febrile patients suspected infection, there were 80 non-infectious patients, including 51 non-infectious SIRS patients, and 109 infection patients, including 53 sepsis patients. The neutrophil ratio, CRP, IL-6, procalcitonin, and SOFA score of non-infectious SIRS patients were lower than those of the sepsis group, and the differences were all statistically significant ( Z=-2.70, -3.11, -2.16, -3.76 and -2.33, respectively, all P<0.05). The (PLA2G7-PLAC8)ΔCt value in the non-infectious SIRS group was 4.38(1.41), which was lower than 8.18 (6.19) in the sepsis group, with a statistically significant difference ( U=193.50, P<0.001). The area under the receiver operating characteristic curve (AUROC) for (PLA2G7-PLAC8)ΔCt value in the differential diagnosis of sepsis and non-infectious SIRS was 0.859, with the optimal cut-off value of 5.86. The sensitivity and specificity were 82.2% and 71.9%, respectively. When combined with procalcitonin, the AUROC was 0.917, with a sensitivity of 95.6% and specificity of 70.6%. Conclusions:The (PLA2G7-PLAC8)ΔCt value in peripheral blood has good clinical value for early identification of sepsis and non-infectious SIRS, especially when combined with procalcitonin, which could further improve the accuracy of differential diagnosis.

BACKGROUND:Clinical studies have found good analgesic effects of silver needle-thermal conduction therapy in patients with myofascial pain syndrome,but the exact mechanism remains unclear. OBJECTIVE:To observe the effect of silver needle-thermal conduction therapy on silent information regulator homolog 3(SIRT3)changes and mitochondrial ultrastructure in a rat model of myofascial pain syndrome. METHODS:Twenty rats were randomly selected from 26 Sprague-Dawley rats and were subjected to percussion combined with motor fatigue for replicating the rat model of myofascial pain syndrome.Sixteen rats that were successfully modeled were randomly divided into model group and silver needle-thermal conduction therapy group(treatment group),with eight rats in each group.The remaining rats were used as controls(normal group).The treatment group was treated with silver needle-thermal conduction therapy.Mechanical withdrawal threshold and thermal withdrawal latency of rats were measured at 1 day before modeling,1 day after modeling and 14 days after treatment.Electromyographic activities of the right medial femoral muscle were measured at 14 days after treatment.The right medial femoral muscle tissue was taken for hematoxylin-eosin staining to observe the local morphology and for transmission electron microscopy to observe the mitochondrial ultrastructure.Western blot assay was performed to detect SIRT3 expression. RESULTS AND CONCLUSION:Pain threshold:The mechanical withdrawal threshold and thermal withdrawal latency of the model and treatment groups were significantly decreased compared with those in the normal group and before modeling(P＜0.01).After treatment,the mechanical withdrawal threshold and thermal withdrawal latency of rats were significantly higher in the treatment group compared with the model group(P＜0.01).Electromyography:The rats in the model group showed spontaneous electrical activity in the right medial femur,while the rats in the treatment group showed reduced spontaneous electrical activity,longer time frame(P＜0.01)and lower wave amplitude(P＜0.05)compared with the model group.Hematoxylin-eosin staining:In the normal group,rat muscle fibers arranged closely and regularly.In the model group,the muscle fibers of rats were atrophied,degenerated,and disordered in arrangement.In the treatment group,rat muscle structure disorder improved.Mitochondrial microstructure:Under the transmission electron microscope,mitochondrial structure in the normal group was normal;mitochondrial swelling with broken or disappeared cristae appeared in the model group;mitochondrial swelling in the treatment group was obviously relieved or tended to be normal.SIRT3 expression:SIRT3 expression was significantly downregulated in the model group compared with the normal group,but was significantly upregulated in the treatment group compared with the model group(P＜0.05).To conclude,abnormalities in local muscle mitochondria and downregulation of SIRT3 expression suggest the presence of impaired energy metabolism in the rat model of myofascial pain syndrome.Mitochondrial changes recover and are close to normal after the silver needle-thermal conduction therapy,and the expression of SIRT3 is also upregulated close to the normal group,indicating the silver needle-thermal conduction therapy may play a therapeutic role by promoting mitochondrial repair and improving energy metabolism disorder.

Objective To investigate the effect of hairy and enhancer of split 5(HES5)on transdifferentiation and apoptosis of renal tubular epithelial cells induced by TGF-β1 and its potential mechanism.Methods The differentially expressed genes in GSE66494 data were analyzed and screened.The mouse model of unilateral uretera obstruction(UUO)was established,and the expression level of HES5 was detected in the renal tissue.HK-2 cells were treated with 10 ng/mL TGF-β1 for 24 h to establish a tubular epithelial-mesenchymal transition(EMT)model,and then qRT-PCR and Western blotting were performed to detect the expression of HES5 at mRNA and protein levels.After HK-2 cells were transfected with the plasmid overexpressing HES5,the protein levels of fibronectin,collagen Ⅰ,vimentin,apoptosis markers Bax and Bcl2 were detected in 24 h later.Then,HK-2 cells were divided into Control group,siHES5 group,TGF-β 1 group,and siHES5+TGF-β1 group.The protein level of fibrosis and apoptosis markers were measured in above groups with Western blotting.TUNEL staining and flow cytometry were employed to detect cell apoptosis.Western blotting was applied to determine the protein levels of AKT,p-AKT,PI3K and p-PI3K.HK-2 cells overexpressing HES5 were treated with PI3K inhibitor LY294002,and the expression of vimentin was detected.Results The expression of HES5 was significantly up-regulated in both chronic kidney disease(CKD)and fibrotic kidneys of mice.Overexpression of HES5 promoted the synthesis of fibronectin,collagen Ⅰ,vimentin and Bax in HK-2 cells,and inhibited the expression of Bcl2(P＜0.05).HES5 knockdown not only down-regulated the expression of fibrosis markers,but also inhibited the apoptosis of HK-2 cells.Furthermore,HES5 knockdown inhibited the activation of PI3K/AKT signaling pathway induced by TGF-β1 in HK-2 cells(P＜0.05).Inhibitors of the PI3K/AKT signaling pathway inhibitor attenuated the induction of HES5 on vimentin.Conclusion HES5 knockdown inhibits the transdifferentiation and apoptosis in TGF-β1-induced renal tubular epithelial cells,which may be related to the decreased activity of the PI3K/AKT signaling pathway.
