Abstract Hyperuricemia (HUA) is a metabolic disorder syndrome caused by purine metabolism dysregulation, and its prevalence increases year by year. The development and progression of HUA are accompanied by significant alterations in the composition of intestinal microbiota, making probiotics a potential and safe method to reduce serum uric acid. Probiotics ameliorate HUA through three pathways: competing with intestinal epithelial cells for purine absorption to decrease uric acid synthesis, inhibiting xanthine oxidase activity through modulation of inflammatory cytokines to reduce the conversion of purine to uric acid, as well as restoring and maintaining an orderly state of the gut microbiota to facilitate normal uric acid excretion. This article reviews the role of probiotics in ameliorating HUA, so as to provide the reference for the application of probiotics in the prevention and intervention of HUA.

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.

Objective: The study aimed to analyze the association between different types of obesity and dyslipidemia among rural primary and middle school students in Zhejiang Province, so as to inform strategies for prevention and control of childhood obesity and hyperlipidemia. Methods: As part of Nutrition Improvement Programme for Rural Compulsory Education Students, 1 244 participants were selected by stratified cluster random sampling in 5 counties of Zhejiang Province during September to December 2021. Physical examination, detection of blood lipid and questionnaire survey were conducted. The Chi -square test and Logistic regression analyses were used to assess the association between different types of obesity and dyslipidemia. Results: The prevalence rates of overweight, obesity, abdominal obesity, and hyperlipidemia were 15.11%, 12.46%, 17.60%, and 21.78%. Obesity and abdominal obesity were correlated to high risk of high triglycerides ( OR =3.97, 95% CI =2.54-6.20; OR =4.45, 95% CI =2.95- 6.72 )( P <0.05). Compared with the non overweight and obese group with normal waist circumference,the overweight and obesity group were correlated to high risk of high cholesterol ( OR=2.53, 95%CI =1.45-4.42, P <0.05). Abdominal overweight or obese group had the highest risk for dyslipidemia and triglycerides ( OR =1.82, 95% CI =1.33-2.48; OR =3.64, 95% CI =2.45-5.43) ( P < 0.05). Conclusions The prevalence rates of overweight, obesity, abdominal obesity, and hyperlipidemia are relatively high in rural primary and middle school students of Nutrition Improvement Programme for Rural Compulsory Education Students in Zhejiang Province. Abdominal obesity is a more important risk factor for hyperlipidemia. Waist circumference should be the focus of considerable attention.

Objective: To understand current status and related factors of breakfast among primary and secondary school students in Zhejiang Province, so as to provide a scientific basis for improving breakfast habits of primary and secondary school students. Methods: During May to November of 2023, 33 326 students from grade four to six of primary schools and grade one to two of secondary schools were selected from 90 counties and cities in Zhejiang Province by using the stratified cluster random sampling method. General information and breakfast consumption were collected by questionnaire. Multivariate Logistic regression was used to analyze the related factors of breakfast. Results: About 81.29% of the primary and secondary school students reported regular breakfast consumption. The rate of regular breakfast consumption was higher on the school days (92.23%) than on the weekends (85.17%), and higher in primary school students (85.83%) compared to secondary school students (74.71%), with statistically significant differences ( χ 2=827.42, 655.03, P <0.01). About 49.19% of primary and secondary school students had their breakfast within 10 minutes or less, and 83.30% of primary and secondary school students had 3-5 food groups for breakfast. The proportions of students who consumed cereals and potatoes, milk, and eggs were respectively 18.76%, 28.85%, 14.63%. About 22.84%, 28.00 %, 32.60% and 32.23% of the students had no meat, soybeans, vegetables and fruits in their breakfast. The results of multivariate Logistic regression analysis showed that girls, rural area, secondary school, place of living (dormitory, others), migrant parent (one or both outside the hometown), late bedtime (22:00-22:59, 23:00 and later) and late wake up time (9:00 and later) on the weekends were positively correlated with no having breakfast every day ( OR=1.22, 1.40, 1.46, 1.20, 1.20, 1.34, 1.36, 1.41 , 3.51, 2.32, P <0.05). The time of physical activity per day (30-<60, 60-<90, 90-120, >120 min), bedtime (21:00-21:59, 22:00-22:59) and wake up time (6:00-6:59, 7:00-7:59) on school days were negatively correlated with no having breakfast every day ( OR=0.75, 0.64, 0.67, 0.64, 0.77, 0.82, 0.75, 0.67, P <0.05). Conclusions There is a considerable number of primary and secondary school students with irregular breakfast consumption, which are related to multiple factors. Therefore, it is necessary to strengthen nutrition education and improve the behavior of breakfast for primary and secondary school students.

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.

Purpose To investigate the clinical pathologic features of five SMARCA4-deficient non-small lung cancers(SMARCA4-dNSCLCs).Methods Five cases of SMARCA4-dNSCLC was underwent by HE,immunohistochemical staining,and molecular detection,analyzed their clinicopathological char-acteristics and reviewed relevant literatures.Results All 5 ca-ses were male,and mean age was 66 years.Five patients had a history of smoking,three patients were treated with cough and blood in sputum as the first symptom,one was treated with a history of pulmonary tuberculosis combined with limb mobility disorder,and one was diagnosed with pulmonary nodules by physical examination.Under microscopic observation,tumor cells were poorly differentiated,with solid nest sheet distribu-tion,some with glandular structure,tumor cells had abundant e-osinophilic or transparent cytoplasm,vacuolar nuclear chroma-tin,nucleoli was visible,and nuclear mitosis was common.In-flammatory cell infiltration and sheet of necrosis were seen in the stroma.Immunohistochemical staining showed 5/5 diffuse ex-pression of CK(AE1/AE3)and CK7,5/5 loss expression of BRG1,1/5 diffuse expression of p40 and CK5/6,and Ki67 proliferating index ranged from 20％to 90％.FISH tests showed that 4/4 SMARCA4 genes missed.Five patients were followed up for 2-15 months,3 patients died and 2 patients survived.Conclusions SMARCA4-dNSCLC can have extensive morphologi-cal features,high degree of malignancy,and complicated treat-ment.BRG1 deficiency is helpful for diagnosis.Deepening the understanding of SMARCA4-dNSCLC can help the clinical cor-rect choice of treatment strategies and accurately evaluate patient prognosis.

OBJECTIVE To explore the mechanism of Kuaisong yin in the prevention and treatment of constipation. METHODS Slow transit constipation （STC） model was established with Compound difenoxylate tablet in mice and rats. Two batches of mice were divided into blank group， model group， positive control group （Maren soft capsule， 0.64 g/kg）， Kuaisong yin low-dose， medium-dose and high-dose groups （3.2， 6.4， 12.8 g/kg）， with 10 mice in each group. The effect of Kuaisong yin on constipation in mice was evaluated by intestinal propulsion experiment and defecation experiment. Rats were divided into blank group， model group， positive control group （Maren soft capsule，0.36 g/kg）， Kuaisong yin low-dose and high-dose groups （2.4， 4.8 g/kg）， with 7 or 8 rats in each group. They were given relevant medicine once a day for 1 week. The metabonomics of serum and urine of rats were analyzed by UPLC-Q-TOF-MS/MS technology. RESULTS Compared with model group， the ink propulsion rate and 5 h defecation volume of mice in Kuaisong yin high-dose group were significantly increased （P＜0.05）； the first defecation time of mice in Kuaisong yin medium-dose and high-dose groups was significantly shortened， and the quality of defecation was significantly reduced within 5 h （P＜0.05 or P＜0.01）. Serum metabonomics screened 16 compounds （such as proline， propionylcarnitine， hemolytic phosphatidylcholine， etc.） and 6 metabolic pathways （such as sphingomyelin metabolism， arginine and proline metabolism， sphingolipid biosynthesis-lactose and neolactone series）. Urine metabonomics screened 20 different metabolites （such as prostaglandin A2， L-valine， phosphatidylcholine， sphingomyelin， etc.） and 8 metabolic pathways （such as valine， leucine and isoleucine biosynthesis， sphingomyelin metabolism， pyruvate metabolism， etc.）. CONCLUSIONS Kuaisong yin can play a role in improving constipation by regulating different metabolites such as hemolytic phosphatidylcholine， phosphatidylcholine， prostaglandin A2， L-valine， proline， and regulating metabolic pathways such as multiple amino acid metabolism， sphingomyelin metabolism， etc.

OBJECTIVE To study the mechanism of Compound zaoren granule in improving insomnia. METHODS Forty-nine mice were divided into blank group， model group， positive control group 1 （Estazolam tablets 0.5 mg/kg），control group 2 （Shumian capsule 0.6 g/kg）， Compound zaoren granule low-dose， medium-dose and high-dose groups （2.5， 5， 10 g/kg）， with 7 mice in each group. The insomnia model was established by chronic unpredictable mild stress combined with 4-chloro-DL- phenylacetic acid. The behavioral changes of mice were investigated through open field test and pentobarbital sodium synergistic hypnosis experiment， as well as the pathomorphology of mice hypothalamus tissue was observed by HE staining. The metabonomics analysis and multivariate statistical analysis of serum in mice were performed by UHPLC-Q-TOF-MS/MS， and the differential metabolites were screened out； the metabolic pathway analysis was conducted based on MetaboAnalyst 5.0 database. RESULTS Compared with blank group， the total travelling distance， the number of entering the central region and the moving distance in the central region of the model group were significantly reduced （P＜0.05）， the proportion of total rest time was significantly increased （P＜0.05）， the sleep duration of mice was significantly shortened （P＜0.05）， and hypothalamic nerve cells damaged and severely vacuolated. Compared with model group， the total travelling distance of Compound zaoren granule low-dose and medium-dose groups were increased significantly and the proportions of total rest time of those groups were decreased significantly （P＜0.05）， and the sleep duration of mice in Compound zaoren granule high-dose group was prolonged significantly （P＜0.05）； the hypothalamic nerve cells of mice in each administration group recovered to varying degrees， and the hypothalamus histiocytes of mice in the Compound zaoren granules high-dose group were closer to those in the blank group. A total of 18 differential metabolites （such as phenylalanine， taurine， norvaline， methionine） and 4 important amino acid metabolic pathways （L-phenylalanine， tyrosine and tryptophan biosynthesis； taurine and hypotaurine metabolism； L-phenylalanine metabolism； cysteine and methionine metabolism） were identified through metabolomics analysis. CONCLUSIONS Compound zaoren granules can normalize the disordered metabolism in vivo by regulating differential metabolites such as phenylalanine， taurine， and four amino acid metabolic pathways， so as to improve insomnia.

Objective:To compare the clinical efficacy and safety of continuous dosing or alternate-day dosing of apatinib combined with SOX regimen as first-line treatment for patients with advanced gastric cancer.Methods:A total of 52 patients with human epidermal growth factor receptor 2 (HER2) negative and inoperable locally advanced or advanced gastric cancer who were pathologically diagnosed from January 2018 to January 2021 in the Second Affiliated Hospital of Shandong First Medical University were collected. The patients were divided into continuous dosing group and alternate-day dosing group by random number table method. The continuous dosing group received apatinib (250 mg, once a day) combined with SOX regimen (S-1+oxaliplatin); the alternate-day dosing group received apatinib (250 mg, once every other day) combined with SOX regimen. Twenty-one days were a cycle, and the efficacy was evaluated after 2 cycles. After 4-6 cycles, patients with stable disease received apatinib and S-1 for maintenance therapy. The therapeutic effects and adverse reactions of the two groups were compared.Results:The curative effect could be evaluated in 51 patients, including 26 in the continuous dosing group and 25 in the alternate-day dosing group. The disease control rates in the continuous dosing group and the alternate-day dosing group were 84.6% (22/26) and 76.0% (19/25) ( χ2 = 0.60, P = 0.499), and the median progression-free survival time was 7.50 months (95% CI 6.17-8.83 months) and 8.30 months (95% CI 6.99-9.61 months) ( χ2 = 0.71, P = 0.401), and the median overall survival time was 15.50 months (95% CI 11.30-19.69 months) and 15.60 months (95% CI 13.63-17.57 months) ( χ2 = 1.82, P = 0.177). The main adverse reactions in the two groups were leukopenia, thrombocytopenia, hypertension, nausea, vomiting, fatigue, hand-foot syndrome, proteinuria, liver and kidney damage. The incidence rates of ≥grade 3 adverse reactions in the continuous dosing group and the alternate-day dosing group were 42.3% (11/26) and 12.0% (3/25), and the difference was statistically significant ( χ2 = 4.46, P = 0.035). Conclusions:The efficacy of continuous dosing or alternate-day dosing of apatinib combined with SOX regimen as first-line treatment for advanced gastric cancer is similar, but the incidence of ≥grade 3 adverse reactions in alternate-day dosing group is lower, which improves the compliance and tolerance of patients.
