As one of the common systemic vasculitides in children， IgA vasculitis is closely associated with the interaction of "Wind pathogen" and "turbid stasis" in its pathogenesis. Based on the blood turbidity theory， this paper proposes "wind agitating blood turbidity and collateral damage" as the core pathogenesis. Regarding treatment， the sequential therapeutic principle of "stanch bleeding， activating blood circulation， and nourishing blood" is adopted， and combined with the dynamic application of wind-dispelling medicinals to "expel， search， and guard against wind"， turbidity-removing method is applied throughout all stages. In the acute stage，it is recommended to clear heat and purify turbidity， stanch bleeding and secure the collaterals. In the prolonged stage， the method of dissipating stasis and clearing up turbidity should be used， as well as activating blood circulation and unblocking the collaterals. In the recovery stage， it is advised to nourish blood to flourish the collaterals， reinforce healthy qi and resolve turbidity. This therapeutic system integrates the elimination of pathogens and the reinforcement of healthy qi to clear and resolve blood turbidity， ultimately achieving holistic collateral repair through securing， unblocking， and nourishing the collaterals， which provides new insights into the treatment of this disease in traditional Chinese medicine.

The clinical diagnosis and treatment of urinary tract infection has long faced the challenges of insufficient standardization of diagnosis and treatment pathways,irrational use of antimicrobial drugs and high recurrence rate.How to optimize the hierarchical diagnosis and treatment pathway of urinary tract infection,standardize the use of antimicrobial drugs,and reduce the recurrence rate have always been the focus of clinical attention.There is significant heterogeneity in the existing diagnostic criteria for urinary tract infection,which seriously affects the comparability and evidence integration of clinical and research studies.In order to solve the above problems,a consensus on global multidisciplinary diagnostic criteria for urinary tract infection has been formed by international multidisciplinary experts after three rounds of Delphi method.Breaking through the traditional classification framework,the consensus innovatively established a four-dimensional quantitative scoring system including local symptoms and signs,systemic inflammatory response,quantitative analysis of pyuria and urine culture results,and established a hierarchical standard for stepwise urinary tract diagnosis according to the scoring threshold.Based on the key citations related to the consensus,this paper interprets in detail the basis for the selection of core indicators and the establishment of thresholds for the diagnosis of urinary tract infection in the consensus,and focuses on the key issues and implementation paths of the consensus in localization practice.This consensus provides a unified standard for standardizing the clinical diagnosis and treatment of urinary tract infection,improving the homogeneity of clinical research through standardized diagnostic processes,and promoting the standardization of UTI drug research and development and the rational use of antibiotics and precision.

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.

BACKGROUND:The asymmetrical biomechanical environment of adolescent idiopathic scoliosis can lead to further wedge deformation of the vertebral body,which may affect cardiopulmonary function and compress nerves in severe cases.Adolescent idiopathic scoliosis with different degrees of scoliosis should be treated with exercise,bracing,and surgery.However,the mechanical mechanism of selecting an orthopedic approach remains unclear due to the individual variability of patients.OBJECTIVE:To investigate the biomechanical mechanism of different orthopedic modalities for the treatment of adolescent idiopathic scoliosis to provide a basis for clinical selection of treatment modalities based on the spine model of adolescent idiopathic scoliosis patients.METHODS:Based on the CT images of an adolescent idiopathic scoliosis patient,a scoliosis model(C7-L5)was reconstructed in Mimics software in three dimensions,and lateral thrust force was applied at the T8/T9 thorax and vertical distraction force was applied over the C7 vertebra with the magnitude of 20,40,60,80,100,and 120 N.The intervertebral disc stress and vertebral displacement in concave and convex sides,and Cobb angle of the spine were analyzed under two orthopedic modalities.RESULTS AND CONCLUSION:(1)With lateral thrust,there was no significant change in the C7T1-T7T8 intervertebral disc.The concave and convex stress of T7T8-L4L5 segment decreased first and then increased with the increase of lateral thrust force.The correction effect of lateral thrust on the segment near T8T9 was obvious and weakened with the extension of the segment to the cephalic and caudal ends.At 120 N of lateral thrust,the thoracic Cobb angle changed from 53.2° to 32.5° and the lumbar Cobb angle changed from 50.2° to 43.9°.(2)With the vertical distraction,the thoracic intervertebral disc stresses first decreased and then increased,and all the lumbar disc stresses decreased.The C7 displacement was the most obvious,and the correction effect gradually diminished with the segment extended to the caudal end.At a vertical distraction force of 120 N,the thoracic Cobb angle changed from 53.2° to 39.4° and the lumbar Cobb angle changed from 50.2° to 47.6°.(3)It is concluded that both orthopedic modalities provide improvement in the degree of scoliosis,with the thoracic correction being greater than the lumbar correction.Also,the asymmetric stress distribution on the concave and convex sides is improved,which contributes to normal bone growth.A vertical distraction approach is appropriate for larger Cobb angles,and a lateral thrust approach is appropriate for smaller Cobb angles.The results of this study help to understand the mechanism of spinal orthosis and provide a theoretical basis for the choice of orthopedic approach.

Objective:To explore the related risk factors of diaphragmatic hernia after thoraco-laparoscopic minimally invasive Mckeown esophagectomy (MIME).Methods:This is a retrospective controlled study. A retrospective analysis was conducted on the clinical data of patients who underwent MIME at the Department of Thoracic Surgery, Fourth Hospital of Hebei Medical University, from January 2016 to December 2023. A total of 619 patients were included. There were 423 males and 196 females, aged (63.7±7.6) years (range: 37 to 87 years). The diagnosis of diaphragmatic hernia after MIME was made based on clinical symptoms and CT scans. Patients were divided into two groups: the diaphragmatic hernia group ( n=16) and the non-diaphragmatic hernia group ( n=603). Clinical data, including age, gender, body mass index (BMI), smoking history, tumor location (upper, middle, and lower thoracic esophagus), preoperative neoadjuvant therapy history, and tumor staging, were collected and analyzed. A BMI of 25 kg/m2 and age of 65 years were used as cutoff values. The χ2 test and Fisher′s exact test were used to compare the data between the two groups, and Logistic regression was employed for risk factor analysis. The diaphragmatic hernia group and non-diaphragmatic hernia group were matched in a 1∶3 ratio with a caliper value of 0.02 by propensity score matching. Kaplan-Meier method was used for survival analysis and compared using the log-rank test for between-group differences. Results:The proportion of patients with diaphragmatic hernia after MIME who underwent surgical treatment was 6/16. Statistically significant differences were observed between the diaphragmatic hernia group and the non-diaphragmatic hernia group in terms of age ( χ2=16.057, P<0.01), BMI ( χ2=16.057, P<0.01), and tumor location ( χ2=12.048, P=0.002). Multivariate logistic regression analysis revealed that age ≥65 years ( OR=1.236, P=0.023) and BMI<25 kg/m2 ( OR=0.810, P<0.01) were independent risk factors for the development of diaphragmatic hernia after MIME. Survival analysis showed no significant difference in long-term survival between patients with and without diaphragmatic hernia after MIME ( P=0.187), and whether patients with diaphragmatic hernia underwent surgery was not associated with long-term prognosis ( P=0.560). Conclusion:Patients with BMI<25 kg/m 2 and age ≥65 years are independent risk factors for diaphragmatic hernia after MIME. The occurrence of diaphragmatic hernia is not associated with prognosis, and whether patients with diaphragmatic hernia undergo surgery does not affect the prognosis.
