Immunoglobulin A (IgA) nephropathy is a globally prevalent type of primary glomerulonephritis, characterized by complex symptoms and diverse clinical manifestations. The internationally recognized " multiple hit hypothesis" explains the systemic immune disease features of IgA nephropathy. However, current treatment strategies primarily focus on local pathological changes, inadequately addressing its complex systemic mechanisms. The " qi cycle in round" theory, an integral concept of the academic thought of HUANG Yuanyu, a prominent medical expert from the Qing Dynasty, offers a concise and insightful framework for understanding complex pathologies. For example, this theory provides valuable insights for elucidating the pathogenesis of IgA nephropathy and guiding its clinical management by simplifying intricate systemic processes. This study applies the " qi cycle in round" theory to postulate that patients with IgA nephropathy experience disrupted qi flow owing to spleen-stomach qi deficiency and dampness-heat accumulation. These imbalances manifest as internal symptoms, such as diarrhea; external vulnerability to illness; upper body symptoms, like sore throat; and lower body symptoms, such as hematuria and proteinuria. Pathologically, the condition is characterized by immune complex deposition. This article also emphasizes strategies that prioritize tonifying spleen-stomach qi to enhance the pivotal functions of transportation and transformation. Regulating qi and relieving stagnation are emphasized to harmonize ascending and descending dynamics. Additionally, eliminating turbidity and unblocking collaterals are highlighted to promote qi transformation. These approaches aim to restore the harmonious operation of organ qi dynamics and harmonious qi transformation functions. This study aims to provide a reference for syndrome differentiation and IgA nephropathy treatment using traditional Chinese medicine based on the " qi cycle in round" theory.

Diabetes has long been considered a risk factor in implant therapy and impaired wound healing in soft and hard oral tissues. Magnesium has been proved to promote bone healing under normal conditions. Here, we elucidate the mechanism by which Mg²⁺ promotes angiogenesis and osseointegration in diabetic status. We generated a diabetic mice model and demonstrated the alveolar bone healing was compromised, with significantly decreased angiogenesis. We then developed Mg-coating implants with hydrothermal synthesis. These implants successfully improved the vascularization and osseointegration in diabetic status. Mechanically, Mg²⁺ promoted the degradation of Kelch-like ECH-associated protein 1 (Keap1) and the nucleation of nuclear factor erythroid 2-related factor 2 (Nrf2) by up-regulating the expression of sestrin 2 (SESN2) in endothelial cells, thus reducing the elevated levels of oxidative stress in mitochondria and relieving endothelial cell dysfunction under hyperglycemia. Altogether, our data suggested that Mg²⁺ promoted angiogenesis and osseointegration in diabetic mice by regulating endothelial mitochondrial metabolism.

Objective: To investigate the prospective effects of intake of each food group on the development of lung function of pupils,so as to provide theoretical basis for promoting the healthy development of lung function and preventing chronic respiratory diseases in Chinese children. Methods: A cluster stratified sampling method was used to select a total of 893 pupils in grades 2-5 from Chengdu in November 2021. Dietary data of respondents were collected using a food frequency questionnaire within the past year,then the food group intake was categorized into T1, T2 and T3 from low to high by the trichotomous method, and anthropometric measurements including lung capacity were obtained in 2022. Logistic regression models and test for trend were used to analyze the prospective effects of intake of each food group on lung function development of pupils. Results: Among male students, consumption of vegetables [118.6(50.5, 188.2)g/d] and milk and dairy products [200.0(73.3, 250.0)g/d] were higher in the excellent lung capacity group than in the non excellent lung capacity group [90.0(37.1, 192.9), and 178.6(35.7, 250.0)g/d],with statistically significant differences ( Z =-1.98, -2.24); among girls, the group with excellent lung capacity consumed less staple food [391.1(273.6, 511.4)g/d] than the group with non excellent lung capacity [407.4(309.5, 594.3)g/d], and the group with excellent lung capacity consumed more aquatic products [31.2(14.6, 69.8)g/d] and milk and dairy products [215.0(107.1, 250.1) g/d ] than that of the non excellent lung capacity [19.4(10.7, 58.3), 114.3(35.7, 250.0)g/d] ( Z =-2.01, -3.33, -5.10)( P < 0.05 ). After adjusting for energy, body mass index Z score(BMI Z ), mother s education level, averge family income monthly, whether presence of smokers in the living environment, and whether participation in physical activities during the past week, among male students, T3 group of vegetable intake ( OR =0.48, 95% CI = 0.27-0.86), T2 group of bean and soy product intake ( OR = 0.52 , 95% CI =0.27-0.96)，T2 and T3 groups of milk and dairy products intake (T2： OR =0.54, 95% CI =0.31-0.93; T3： OR = 0.52 , 95% CI =0.30-0.90) were negatively associated with non excellent lung capacity ( P <0.05). Among girls, T3 group of aquatic product intake( OR =0.52, 95% CI =0.28-0.97), T2 and T3 groups of milk and dairy product (T2: OR =0.44, 95% CI =0.25- 0.76 ;T3: OR =0.33, 95% CI =0.19-0.59) were negatively associated with nonexcellent lung capacity, whereas the T2 group of red meat intake ( OR =2.51, 95% CI =1.37-4.67) was positively associated with non excellent lung capacity. Non excellent lung capacity was found to be negatively associated with vegetable and milk and dairy product intake in boys by test for trend; in girls, milk and dairy products intake was negatively associated with non excellent lung capacity, whereas red meat intake was positively associated with non excellent lung capacity ( t =-1.13，-0.44；-3.03，1.95, P trend <0.05). Conclusions Milk and dariy products intakes reduce the risk of non excellent lung capacity in pupils, vegetables intakes reduce the risk of non excellent lung capacity in boys, and the intake of red meat increases the risk of non excellent lung capacity in girls. Promoting rational food choices is necessary for children to improve healthy lung development.

Objective: To determine the association between the intake of five major types of prepackaged foods and the growth and development of school aged children, so as to provide a theoretical basis for guiding school aged children and their parents to make healthy prepackaged food choices. Methods: Based on data from the South West China Childhood Nutrition and Growth Cohort (SCCNG), 381 children (6-11 years of age) were selected by stratified cluster sampling. Dietary intake and pubertal development were collected using questionnaires, and anthropometric measurements were obtained. Children were followed up until November 2022. Binary Logistic regression models were used to analyze the prospective association between prepackaged food intake and the growth and development of school aged children. Results: The total intake of the five major types of prepackaged foods was 316.1 (197.1,501.4) g/d. After 2 years of follow up evaluations, 16.5% of school aged children were shown to be overweight and obese. Early spermarche occurred in 12.6% of boys and early menarche occurred in 15.4% of girls. The following findings were suggested after adjusting for the mothers education level, average gross monthly family income, whether or not the family had one child only, geographic area of residence, body mass index Z score, average duration of daily exercise, and total dietary energy intake: convenience food intake might increase the risk of early spermarche ( OR =9.37); fruit and vegetable intake might decrease the risk of early spermarche and menarche ( OR =0.33,0.17); and fish, poultry, meat, and egg intake might increase the risk of early menarche ( OR =7.59)( P <0.05). Intake of the five types of prepackaged foods was not associated with being overweight or obese after adjusting for confounders ( OR =1.40, 0.57, 0.73, 1.33,1.57, P >0.05). Conclusions The relationship between intake of the five major types of prepackaged foods and pubertal development is inconsistent and no significant correlation was detected between the intake of prepackaged foods and overweight or obese children. Nutrition education should be strengthened to help children and their parents choose healthy prepackaged foods.

Diabetic kidney disease(DKD)is a severe complication of diabetes.Its incidence increases annually,posing a significant burden on public health.The strategy of symptomatic treatment based on pathogenesis differentiation,focusing on identifying pathogenesis,is particularly meaningful for managing complex and variable chronic diseases like DKD.Within this framework,the state of latent heat persists throughout DKD,with"latent heat causing accumulation"identified as the core pathogenesis affecting and promoting the development and progression of DKD.This paper is centered on the concept of"latent heat causing accumulation"and adopts symptomatic treatment based on pathogenesis differentiation as its guiding principle to explore the role of latent heat in DKD.It highlights that the onset of DKD involves environmental and constitutional pathogenesis associated with"the concealment of latent heat"and"stagnant-heat invading collaterals"as the initial pathogenesis,"latent heat causing accumulation"as the core mechanism,and"secondary turbid heat"as the derivative pathogenesis.These pathogenesis factors collectively influence the symptoms,sequelae,and prognosis of DKD.Moreover,this paper provides commonly used prescriptions for different stages,syndrome types,and complications of the disease,aiming to offer a reference for clinical practice in flexibly addressing changes in disease conditions based on varied pathogenesis.
