Based on the view that wind pathogen runs through the entire course of the occurrence and development of nephrotic syndrome， it is proposed that the core pathogenesis of refractory nephrotic syndrome （RNS） in children involves imbalance of the lung， spleen， and kidney， invasion of wind pathogen， and stagnation of turbidity and stasis， and that directing the turbid downward with wind medicinals is the key therapeutic strategy. In clinical practice， according to the distinct pathogenic characteristics of three patterns， including defensive qi insecurity of the lung， yang deficiency with loss of regulation， and binding of turbidity and stasis， three corresponding methods are applied， which are diffusing the lung to consolidate defensive qi， elevating yang to supplement the spleen and kidney， and activating blood to unblock turbidity and stasis. For the pattern of defensive qi insecurity of the lung， wind medicinals are used to penetrate and disperse external pathogens， such as fangfeng （Radix Saposhnikoviae） and mahuang （Herba Ephedrae） for diffusing the lung， dispersing wind， and consolidating defensive qi. For yang deficiency with loss of regulation pattern， wind medicinals are employed to elevate yang and assist transformation， such as shengma （Rhizoma Cimicifugae） and gegen （Radix Puerariae Lobatae） for raising clear yang， warming and activating the spleen and kidney. For binding of turbidity and stasis pattern， wind medicinals with scurrying and collateral‑unblocking properties are used， such as jixueteng （Caulis Spatholobi）， luoshiteng （Caulis Trachelospermi）， and chuanshanlong （Rhizoma Dioscoreae Nipponicae） for dispelling wind， activating blood， resolving stasis， and directing turbidity downward. In all these methods， the core principle is to use wind medicinals to regulate qi movement， open and unblock the sweat pores， and separately eliminate turbid pathogens， thereby providing a theoretical and practical basis for the traditional Chinese medicine diagnosis and treatment of RNS in children.

Objective To study the effect of Liangxue Tuizi Formula(LXTZF)on reactive oxygen species(ROS)-mediated NOD-like receptor thermal protein domain associated protein 3(NLRP3)inflammasome activation in Henoch-Sch?nlein purpura(HSP)rats,and to explore its possible mechanism in the treatment of HSP.Methods Twenty-four rats were divided randomly into four groups:control,model,LXTZF,and compound glycyrrhizin(CG)groups.Except for the control group,a model of HSP was established in the other groups by heat drugs combined with egg albumin.After successful modeling,rats in the LXTZF group were given LXTZF solution 7.47 g/kg,rats in the CG group were given CG solution 13.5 mg/kg by gavage,and rats in the control and model groups were given normal saline solution by gavage once a day for 4 weeks.Samples were collected 8 hours after the last gavage.Skin histopathology changes were observed by hematoxylin and eosin(HE)staining.Serum interleukin(IL)-18 and IL-1βlevels were detected by enzyme-linked immunosorbent assay(ELISA).Changes in ROS levels in the skin were detected by immunofluorescence.Apoptosis-associated speckle-like protein(ASC),NLRP3,cysteinyl aspartate-specific protease-1(Caspase-1)mRNA and protein expression levels in rat skin were detected by real-time quantitative polymerase chain reaction(RT-PCR)and immunohistochemistry and Western blot,respectively.Results The skin pathology in the model group showed obvious inflammatory cell infiltration compared with the control group.Serum IL-18 and IL-1β levels were significantly increased(P＜0.05),skin ROS levels were significantly increased(P＜0.05),and skin ASC,NLRP3,Caspase-1 mRNA and protein expression levels were significantly increased(P＜0.05).Inflammatory cell infiltration in the skin tissues of rats was alleviated in the LXTZF and CG groups compared with the model group,while serum levels of IL-18 and IL-1β were significantly decreased(P＜0.05).ROS levels in the skin were significantly decreased(P＜0.05),and mRNA and protein levels of ASC,NLRP3,and Caspase-1 in the skin were significantly decreased(P＜0.05).Conclusions The mechanism of LXTZF in HSP may be related to the inhibition of ROS-mediated NLRP3 inflammasome activation.

Sinusitis is a prevalent nasal disease in children, characterized by chronic and difficult-to-treat symptoms. Its onset is related to nasal stagnation, gallbladder and lung dysfunctions. This article explores the root cause based on Huangdi Neijing by considering the physiological and pathological characteristics of children. The core pathogenesis of pediatric sinusitis is the transmission of heat from the gallbladder and lung to the brain and nose, disrupting normal nasal function. Wind and heat pathogens often persist, accumulate, and transform into turbid qi, which are common triggers of the disease. Evil qi retention and yin depletion are internal factors that cause the prolonged and unhealed condition of the disease. This article emphasizes individualized treatment approaches based on disease duration and the severity of pathogenic factors. If external pathogens remain uncleared, treatment should focus on dispelling wind, clearing heat, dispersing with pungent medicinals, and dredging nasal orifices. If internal fire is exuberant, clearing lung qi, inhibiting hyperactive liver yang, and clearing exuberant fire should be used to relieve stagnation. In chronic cases with residual pathogens and liver-kidney yin deficiency, nourishing yin, clearing fire, and moistening the nasal orifices are essential. When exuberant heat has subsided, but the symptom of a persistent runny nose continues, leading to the loss of healthy qi and damage to the lung and spleen, treatments that tonify the spleen, benefit the lung, and reinforce healthy qi should be adopted to relieve stagnation. These treatments aim to restore the balance of the body′s vital qi by addressing both the lingering symptoms and the underlying weakness of the lung and spleen. The diagnosis and treatment of pediatric sinusitis based on the theory of "the transmission of heat from gallbladder and lung" can help reduce the recurrence of sinusitis and alleviate symptoms, with the aim of broadening the approach of traditional Chinese medicine in treating this condition.

Objective To study the regulatory effect of Qufeng Xiaodian Formula on serum differential metabolites of allergic purpura,and provide scientific basis for the diagnosis and treatment of allergic purpura in traditional Chinese medicine.Methods Sixty rats were randomly divided into a blank control group(referred to as the blank group),a model group,a compound glycyrrhizin group,a low-dose Qu Feng Xiao Dian Fang group,a medium dose Qu Feng Xiao Dian Fang group,and a high-dose Qu Feng Xiao Dian Fang group according to a random number table method,with 10 rats in each group.The model group was constructed by combining dried ginger,pepper,and long pepper with ovalbumin to create an allergic purpura rat model.After successful modeling,each treatment group was intervened with corresponding drugs for 4 weeks.After 4 weeks,serum was collected and non targeted metabolomics screening of serum differential metabolites was performed using ultra-high performance liquid chromatography quadrupole time-of-flight tandem mass spectrometer(UPLC-QTOF/MS).Subsequently,data extraction and multivariate statistical analysis will be conducted to identify potential metabolic pathways.Results Compared with the control group,there were 91 possible differential metabolites in the serum of the model group rats,corresponding to 20 metabolic pathways;Compared with the model group,there were a total of 43 possible differential metabolites in the serum of rats in the wind dispelling and disease eliminating group,corresponding to 15 metabolic pathways.Among them,there are a total of 12 metabolic pathways.Inflammatory metabolites such as arachidonic acid and ceramide can damage vascular endothelium.Ten biomarkers,including arachidonic acid and ceramide,were significantly abnormal in the serum of the model group rats compared to the normal group.The Qufeng Xiaodian formula can significantly reverse these metabolites and significantly enrich them in arachidonic acid metabolism and sphingolipid metabolism pathways.Conclusion Qufeng Xiaodian Formula has a certain regulatory effect on metabolites such as arachidonic acid and ceramide that affect vascular endothelial injury.

The main pathogenesis of chronic cough in children is the disorder of ascending and descending of qi movement caused by healthy qi deficiency and pathogenic qi retention. The deficiency of lung， spleen， and kidney is the root of the disease， and the retention of phlegm-fluid， food accumulation， and fire from constraint is the branch pathogenesis of the disease. In the treatment， we should reinforce and tonify healthy qi， dispel pathogen and regulate qi， with Yupingfeng Powder （玉屏风散） as the basic prescription. For lung qi deficiency syndrome， modified Yupingfeng Powder could be used for supplementing lung to consolidate the exterior； for lung and spleen qi deficiency syndrome， modified Yupingfeng Powder plus Shenling Baizhu Powder （参苓白术散） could be used for supplementing lung and fortifying the spleen， treating with both supplementation and transformation； for lung kidney qi deficiency syndrome， modified Yupingfeng Powder combined with Suzi Jiangqi Decoction （苏子降气汤） could be used for supplementing lung and replenishing kidneys， absorbing qi to the root. All the above prescriptions could combine the method of dispelling phlegm， promoting digestion and guiding out food stagnation， soothing the liver and draining fire to remove the solid pathogens， in order to treat the root and branch simultaneously， and the cough will stop if the ascending and descending of qi movement recover as usual.
