This paper explores the differentiation and treatment strategies for pediatric IgA vasculitis based on the correlation between blood trubidity theory and oxidative stress. It is proposed that pediatric IgA vasculitis follows an evolution of pathogenesis characterized by "deficiency of healthy qi leading to turbidity generation, accumulation of turbid toxin, and toxin damage to the collateral vessels", which corresponds to the pathological process of oxidative stress, namely decreased antioxidant capacity with accumulation of reactive oxygen species, metabolite deposition, and endothelial cell injury. A staged treatment strategy is proposed. In the acute stage, wind-toxin invading the colla-terals and reckless movement of heat in the blood are the main manifestations, for which the treatment should focus on dispelling wind and venting pathogens, resolving toxins and unblocking the collaterals, with a modified Yinqiao Powder (银翘散) and Xijiao Dihuang Decoction (犀角地黄汤) to regulate oxidative stress burst. In the prolonged stage, intermingling of turbidity and stasis with collateral obstruction is emphasized; treatment should focus on resolving turbidity and dispelling stasis, harmonizing the blood and stabilizing the collaterals, and a modified Simiao Powder (四妙散) and Taohong Siwu Decoction (桃红四物汤) can be used to improve microcirculatory dysfunction. In the remission stage, when healthy qi remains insufficient and residual pathogens persist, treatment should focus on strengthening the root and clearing the source, reinforcing healthy qi and nourishing the collaterals, for which modified Zhibai Dihuang Pill (知柏地黄丸) and Yupingfeng Powder (玉屏风散) is suggested to rebuild the antioxidant defense system.

ObjectiveTo investigate the therapeutic effect and mechanism of modified Chunzetang on bladder fibrosis and detrusor function in rats with neurogenic bladder urinary retention induced by spinal cord injury. MethodsIn this study, an improved Hassan Shaker spinal cord transection method was used to establish a model of neurogenic bladder urinary retention induced by spinal cord injury, and rats with a spinal cord injury behavior score of 0 were selected for follow-up experiments. The selected rats were randomly divided into a model group (normal saline gavage), low-dose traditional Chinese medicine (TCM) group (gavage of 14.4 g·kg-1 modified Chunzetang), high-dose TCM group (gavage of 28.8 g·kg-1 modified Chunzetang), positive drug group [intraperitoneal injection of 0.05 g·kg-1 nuclear transcription factor-κB (NF-κB) inhibitor pyrrolidine dithiocarbamate (PDTC)], and combination group (intraperitoneal injection of 0.05 g·kg-1 PDTC + gavage of 28.8 g·kg-1 modified Chunzetang). The rats in these groups were administrated with corresponding drugs once a day for four weeks. The BL-420s biofunction acquisition system was used in the experiment to calculate the urodynamic indexes, and the isolated bladder was quickly weighed. The detrusor traction experiment was used to record the minimum bladder contraction tension and frequency in each group. The pathological morphology and tissue fibrosis of detrusor in each group observed by Hematoxycin-eosin (HE) staining and Masson staining were compared. The expression level of α-smooth muscle actin (α-SMA) was detected by immunohistochemistry. Western blot was used to detect the protein expression of NF-κB p65, nuclear transcription factor-κB suppressor protein α (IκBα), transforming growth factor-β1 (TGF-β1), type Ⅰ collagen (ColⅠ), and type Ⅲ collagen (ColⅢ) in bladder tissue of rats in each group. Enzyme-linked immunosorbent assay (ELISA) was used to detect the changes in serum levels of IL-6, IL-1β, and TNF-α. ResultsCompared with that in the sham operation group, the pressure at the urinary leakage point in the model group decreased (P<0.01), and the bladder mass, bladder contractile tension, maximum bladder capacity, and bladder compliance increased (P<0.05,P<0.01). HE staining showed that the arrangement of bladder epithelial cells was disordered, and the pathological manifestations such as mucosa and myometria neutrophil infiltration were obvious. The lamina propria structure was destroyed, and the muscle fiber arrangement was disordered. The interstitial widening and tissue edema were obvious. Masson staining showed that the bladder wall of the model group had more collagen fiber deposition, and the degree of detrusor fibrosis was more severe. The content of detrusor in the visual field was reduced. At the same time, the protein expressions of NF-κB p65, TGF-β1, IκBα, ColⅠ, and ColⅢ in bladder tissue of rats in the model group were significantly increased (P<0.01), and the serum levels of IL-6, IL-1β, and TNF-α were significantly increased (P<0.05). Compared with that in the model group, the pressure at the urinary leakage point in the modified Chunzetang and positive drug groups was increased (P<0.05), and the wet bladder weight, minimum bladder contractile tension, maximum bladder capacity, and bladder compliance were restored (P<0.05, P<0.01). HE and Masson showed that the bladder epithelial cells were relatively neatly arranged, and the structure of the bladder lamina propria was relatively stable. The detrusor bundles were arranged in an orderly manner, and the interstitium was narrow. The degree of tissue edema was relatively low, and the degree of bladder detrusor fibrosis in the modified Chunzetang and positive drug groups was reduced, while the degree of bladder detrusor fibrosis in the positive drug group and combination groups was not obvious. The results of Western blot showed that the expression of NF-κB p65, IκBα, TGF-β1, ColⅠ, and ColⅢ in bladder tissue, as well as the serum levels of IL-6, IL-1β, and TNF-α in modified Chunzetang and positive drug groups were significantly lower, and the expression of bladder tissue-related proteins and the serum levels of IL-6, IL-1β, and TNF-α in the TCM groups decreased significantly with the increase in dose (P<0.05). The results of immunohistochemistry suggested that modified Chunzetang could fully affect the expression of α-SMA in bladder tissue. ConclusionModified Chunzetang can inhibit collagen deposition in bladder tissue of rats with urinary retention induced by spinal cord injury, delay the occurrence and development of bladder fibrosis, and protect the normal contractile function of bladder detrusor, and its mechanism may be related to inhibiting the NF-κB/TGF-β1 signaling pathway, reducing the production of NF-κB p65, IκBα, TGF-β1, ColⅠ, ColⅢ, and other related proteins, and protecting the muscle strength of detrusor.

IgA vasculitis is a common childhood vasculitis disorder.Its primary clinical manifestation is cutaneous purpura,which is often accompanied by gastrointestinal and joint symptoms.Renal involvement can present as hematuria or proteinuria.This condition is recurrent and protracted,significantly affecting the health of children.The pathogenic factors in pediatric IgA vasculitis are diverse."Wind-toxin damaging collaterals"is presented as the core pathogenesis based on clinical practice and theoretical exploration.This concept essentially entails the latent attack of wind-toxin,collateral damage leading to blood extravasation,and healthy qi deficiency and lingering toxins,with the disease primarily located in the collateral vessels.The disease course is divided into three stages:acute,lingering,and recovery.Clinical practice should adhere to the pathogenesis principles and apply stage-based pattern differentiation and treatment.The acute stage involves wind-toxin attacking collaterals with dampness-heat accumulation.Treatment focuses on dispersing wind,clearing heat,and eliminating dampness to expel wind-toxin from the muscular exterior.The self-prescribed Qufeng Xiaodian Formula is a frequently selected modified formula.The lingering stage features latent wind-toxin in the collaterals and congealed accumulations in the kidney collaterals.Treatment aims to resolve wind-toxin,disperse stasis,and eliminate accumulation to remove densely accumulated wind-toxin.A modified Taohong Siwu Decoction is selected.The recovery stage involves deficient healthy qi with persistent wind assault and lingering toxins.Emphasis should be placed on cultivating the fundamental,strengthening the root,and nourishing yin,as well as supporting the healthy qi to dispel wind and expel toxins,while conditioning the body to prevent recurrence.A modified Guomin Decoction is selected.Clinical application emphasizes the combination of characteristic medicines,such as wind medicines to expel pathogens,insect medicines to identify collaterals,and vine medicines to unblock the meridians,to enhance the effects of identifying wind,resolving toxins,unblocking collaterals,and dispersing congealed accumulations.This study aims to systematically elaborate on the stage-based treatment strategy from the perspective of"wind-toxin damaging collaterals,"providing a theoretical basis and clinical practice reference for the traditional Chinese medicine diagnosis and treatment of pediatric IgA vasculitis.

ObjectiveTo investigate the potential mechanism of Liangxue Tuizi Formula (凉血退紫方, LXTZF) in treating Henoch-Schönlein Purpura (HSP) by examining its regulatory effect on neutrophil extracellular trap (NETs) dysregulation via the rapidly accelerated fibrosarcoma kinase (RAF)/mitogen-activated protein kinase (MEK)/extracellular signal-regulated kinase (ERK) signaling pathway. MethodsSeventy Wistar rats were randomly allocated into a blank control group (n=14) and a modeling group (n=56). Rats in the modelling group underwent an eight-week modelling period to establish HSP rat models with blood-heat syndrome via modified ovalbumin (OVA) induction method combined with oral administration of heat-property Chinese herbal medicine. Fifty successfully modeled rats were subsequently randomly divided into five groups (n=10 per group), model group, compound glycyrrhizin group, LXTZF group, RAF inhibitor group, and LXTZF + RAF agonist group. Additionally, 10 rats were selected from the original blank control group for the final experiment. From the 11th week of modelling, rats in the blank control group and the model group received 1 ml/(100 g·d) ultrapure water via oral administration, in addition to 0.5 ml/(kg·d) 0.9% sodium chloride solution via intraperitoneal injection. The LXTZF group and the compound glycyrrhizin group received 7.5 g/(kg·d) LXTZF granule suspension via gavage, 13.5 mg/(kg·d) compound glycyrrhizin suspension via gavage, respectively. The RAF inhibitor group received 1 mg/(kg·d) GW5074 suspension via intraperitoneal injection and ultrapure water via oral administration; the LXTZF + RAF agonist group received 7.5 g/(kg·d) LXTZF granule suspension via gavage and 1 mg/(kg·d) paclitaxel suspension via intraperitoneal injection. All administrations were performed once daily for 4 weeks. After intervention, skin tissue histopathology was examined by hematoxylin and eosin (H&E) staining, immunoglobulin A (IgA) deposition was assessed via immunofluorescence, serum levels of neutrophil elastase (NE), tumor necrosis factor-α (TNF-α), and vascular cell adhesion molecule-1 (VCAM-1) were measured using enzyme-linked immunosorbent assay (ELISA), serum myeloperoxidase (MPO) level was determined by a colorimetric assay; the mRNA expression levels of RAF, MEK, and ERK in skin tissue were detected by real-time quantitative polymerase chain reaction (RT-qPCR); and the protein expression of RAF, MEK, ERK, as well as phosphorylated MEK (p-MEK) and phosphorylated ERK (p-ERK), were analyzed by Western Blot. ResultsSkin tissue in the blank control group rats remained normal, whereas the model group exhibited neutrophil infiltration and haemorrhage with red blood cell rupture. In all drug intervention groups, neutrophil infiltration and haemorrhagic exudation reduced markedly, with LXTZF group demonstrating the most pronounced improvement. Compared with the blank control group, rats in the model group exhibited enhanced IgA fluorescence intensity in skin tissue, elevated serum levels of NE, MPO, TNF-α and VCAM-1, increased mRNA expression of RAF, MEK, ERK1 and ERK2, as well as heightened RAF protein levels and p-MEK/MEK and p-ERK/ERK ratios (P<0.05). Compared with the model group, the drug intervention groups exhibited reduced IgA fluorescence intensity in skin tissue, along with decreased serum levels of NE, MPO, TNF-α, and VCAM-1 (P<0.05). In LXTZF group and RAF inhibition groups, reduced mRNA expression of RAF, MEK, ERK1, and ERK2 was observed in rat skin tissue, alongside decreased RAF protein levels and reduced p-MEK/MEK and p-ERK/ERK ratios (P<0.05). Compared with LXTZF + RAF agonist group, the compound glycyrrhizin group, LXTZF group, and RAF inhibitior group exhibited reduced IgA fluorescence intensity in skin tissue, decreased serum NE, MPO, TNF-α, and VCAM-1 levels, and decreased MEK mRNA expression and p-MEK/MEK ratio (P<0.05). ConclusionThe potential mechanism by which LXTZF treats Henoch-Schönlein purpura with blood heat syndrome may involve blocking the RAF/MEK/ERK signaling pathway in skin tissue, and suppressing excessive formation of NETs, thereby reducing IgA deposition in dermal microvessels and attenuating systemic inflammatory responses.

Background/Aims:
Liver transplantation is the most effective treatment for the sickest patients with acute-on-chronic liver failure (ACLF). However, the influence of donor age on liver transplantation, especially in ACLF patients, is still unclear.
Methods:
In this study, we used the data of the Scientific Registry of Transplant Recipients. We included patients with ACLF who received liver transplantation from January 1, 2007, to December 31, 2017, and the total number was 13,857. We allocated the ACLF recipients by age intogroup I (donor age ≤17 years, n=647); group II (donor age 18–59 years, n=11,423); and group III (donor age ≥60 years, n=1,787). Overall survival (OS), graft survival, and mortality were com-pared among the three age groups and the four ACLF grades. Cox regression was also analyzed.
Results:
The 1-, 3-, and 5-year OS rates were 89.6%, 85.5%, and 82.0% in group I; 89.4%, 83.4%, and 78.2% in group II; and 86.8%, 78.4%, and 71.4% in group III, respectively (p<0.001).When we analyzed the different effects of donor age on OS with different ACLF grades, in groupsII and III, we observed statistical differences. Finally, the cubic spline curve told us that the relative death rate changed linearly with increasing donor age.
Conclusions
Donor age is related to OS and graft survival of ACLF patients after transplanta-tion, and poorer results were associated with elderly donors. In addition, different donor ages have different effects on recipients with different ACLF grades.

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.

Based on the viewpoint of "sweat pore-qi and liquid-kidney collaterals", it is believed that children's nephrotic syndrome is caused by the core mechanism of sweat pore constraint and closure, qi and liquid imbalance, and kidney collaterals impairment, and it is proposed that the treatment principle is to nourish the sweat pore, regulate qi and fluid, and supplement the kidney and unblock the collaterals. In clinic, guided by sequential therapy and according to the different disease mechanism characteristics of the four stages, including early stage of the disease, hormone induction stage, hormone reduction stage, hormone maintenance stage, the staged dynamic identification and treatment was applied. For early stage of the disease with edema due to yang deficiency, modified Zhenwu Decoction (真武汤) was applied to warm yang and drain water; for hormone induction stage with yin deficiency resulting in effulgent fire, modified Zhibai Dihuang Pill (知柏地黄丸) plus Erzhi Pill (二至丸) was used to enrich yin and reduce fire; for hormone reduction stage with qi and yin deficiency, modified Shenqi Dihuang Decoction (参芪地黄汤) was used to boost qi and nourish yin; for hormone maintenance stage, modified Shenqi Pill (肾气丸) was used to supplement yin and yang. Meanwhile, the treatment also attaches importance to the combination of vine-based or worm medicinals to dredge collaterals, so as to providing ideas for clinical treatment.
