Immunoglobulin A nephropathy （IgAN） is the primary glomerulonephritis with the highest incidence rate in the world. It is also the main cause of end-stage renal disease （ESRD） in China， which has brought heavy economic burden to the society and patient families. Traditional Chinese medicine （TCM） has certain advantages in treating IgAN. In TCM， IgAN is classified into consumptive disease， hematuria， and edema categories， with the location in the kidney and involving the lung， liver， and spleen. Professor Ren Jixue， a master of TCM， believes that kidney deficiency and spleen deficiency are the root causes of IgAN， and the throat is the source of the disease. He proposed the theory of throat-kidney correlation and used the method of tonifying kidney and invigorating spleen as well as detoxifying and relieving sore-throat to treat IgAN， achieving significant therapeutic effects. Studies have shown that IgAN is closely related to mucosal immune defense. IgAN patients often experience recurrent and gradually worsening symptoms due to mucosal infections， and polymeric Ig receptor （PIgR） is an important component of mucosal defense function. The lack of PIgR leads to the accumulation of IgA molecules in the mucosal lamina propria， and the molecules enter the bloodstream in large quantities and ultimately deposit in the kidneys， causing kidney damage. Complement regulatory protein complement receptor type 1 （CR1） exists on red blood cells and glomeruli and has the function of inhibiting the activation and differentiation of B cells， clearing immune complexes， and inhibiting excessive activation of the complement system. Therefore， regulating the immune defense function through the mucosal-renal axis mediated by PIgR-CR1 will be an important target for preventing and treating IgAN. Based on the theory of throat-kidney correlation， this article explores the effects and molecular mechanisms of tonifying kidney and invigorating spleen as well as detoxifying and relieving sore-throat in preventing and treating IgAN by regulating the mucosal-kidney axis mediated by PIgR-CR1. It provides effective theoretical support and a scientific basis for TCM prevention and treatment of IgAN based on the theory of throat-kidney correlation.

To summarize the clinical effect of using boosters for orbital autologous fat injection transplantation.

Objective To explore the mechanism by which puerarin alleviates the cardiotoxicity induced by doxorubicin in myocardial cells. Methods Cells in the logarithmic growth phase were divided into normal control group,model group,low-(20 mmol·L-1),medium-(40 mmol·L-1) and high-(80 mmol·L-1) dose puerarin groups,and positive control group(captopril,1 mmol·L-1). Except for the normal control group,the other groups were co-incubated with 5 mmol·L-1 doxorubicin. Cell viability was assessed using CCK-8 and lactate dehydrogenase (LDH) assays. ROS levels were detected using a ROS probe. Autophagy flux was detected by transfection with HBAD-mcherry-EGFP-LC3 adenovirus. Western Blot was used to measure the protein expression levels of Beclin-1,LC3,p62,p-AMPKα,and AMPKα. Lysosomal function was assessed using a lysosomal probe. Immunofluorescence was used to detect the relative intensity and co-localization of ASMase and LAMP1. Molecular docking analysis was performed to predict the binding capacity of PUE with ASMase. Differential gene expression was analyzed by gene set enrichment analysis. Results Compared to the normal control group,the model group showed reduced cell viability (P<0.01),increased release levels of LDH and ROS (P<0.05,P<0.01),increased number of autophagosomes (P<0.01),and decreased number of autophagic lysosomes (P<0.05). Beclin-1 protein expression and LC3-II/LC3-I ratio decreased(P<0.01),but p62 protein expression increased(P<0.01). Fluorescence intensity of lysosome decreased(P<0.01),whereas fluorescence intensity of ASMase increased(P<0.01). Immunofluorescence co-localization of ASMase and LAMP1 increased (P<0.01),the ratio of p-AMPKα/AMPKα decreased(P<0.05). Compared to the model group,the high-dose puerarin group showed a rebound in cell viability (P<0.05). The medium-and high-dose puerarin groups showed a decreasing trend in LDH level (P<0.05),and all puerarin groups showed a decreasing trend in ROS level (P<0.01). The number of autophagosomes in high-dose puerarin group reduced (P<0.01). The number of autophagic lysosomes in all puerarin groups increased (P<0.05,P<0.01). The high-dose puerarin group showed increased expression of Beclin-1 (P<0.05) and LC3-II/LC3-I ratio,and decreased p62 expression (P<0.01). All puerarin groups showed increased lysosomal fluorescence intensity (P<0.05,P<0.01). The medium-and high-dose puerarin groups showed a decrease in ASMase fluorescence intensity(P<0.05),a reduction in the immunofluorescence co-localization of ASMase with LAMP1 (P<0.01),and an increase in the p-AMPKα/AMPKα ratio (P<0.01). Molecular docking analysis discovered puerarin showed a binding energy of-8.6 kcal·mol-1 with ASMase. Gene enrichment analysis indicated that the differentially expressed genes in the doxorubicin cardiotoxicity model were related to apoptosis,autophagy,and lysosomal function. Conclusion Puerarin can alleviate doxorubicin-induced cardiotoxicity in myocardial cells and protect myocardial cells by regulating autophagy through AMPK/ASMase,as well as restoring autophagic flux.

Objective:To investigate the incidence of thyroid nodule in population of Yangzhou City and analyze the related influencing factors, so as to provide scientific basis for formulating prevention and control strategies for thyroid nodule.Methods:From January to August 2023, permanent residents (≥8 years old) of 36 towns/streets in 6 counties (cities and districts) of Yangzhou City were randomly selected as the survey subjects. A total of 2 033 subjects were included in the study for questionnaire survey, thyroid nodule was examined by B-ultrasound, and urinary iodine and salt iodine level were determined. SPSS 26.0 software was used for χ 2-test and multivariate logistic regression analysis. Results:Among 2 033 survey subjects, 705 patients with thyroid nodule were detected, the detection rate was 34.68%. The detection rate of thyroid nodule in female (40.37%, 480/1 189) was significantly higher than that in male (26.66%, 225/844), and the difference was statistically significant (χ 2 = 40.97, P < 0.001). The results of multivariate logistic regression analysis showed that women [odds ratio ( OR) = 2.07], age (40 - 59 and ≥60 years old: OR = 1.60, 3.17), hypertension ( OR = 1.62) and immediate family members with goiter/nodule ( OR = 2.77) were all positively correlated with the risk of thyroid nodule ( P < 0.05). Conclusion:The detection rate of thyroid nodule in population of Yangzhou City is relatively high, and special attention should be paid to women, those with hypertension, the elderly, and immediate family members with goiter/nodule.

Purpose: This study aimed to evaluate changes in ultrafast pulse wave velocity (ufPWV) in individuals with arterial stiffness and subclinical atherosclerosis (subAS), and to provide cutoff values. Methods: This retrospective study recruited 231 participants, including 67 patients with subAS. The pulse wave velocity was measured at the beginning and end of systole (PWV-BS and PWVES, respectively) using ultrafast ultrasonography to assess arterial stiffness. The right and left common carotid arteries were measured separately, and laboratory metabolic parameters were also collected. Participants were balanced between groups using propensity score matching (PSM) at a 1:1 ratio, adjusting for age, sex, and waist-to-hip ratio as potential confounders. Cutoff values of ufPWV for monitoring subAS were determined via receiver operating characteristic (ROC) curve analysis. Results: PWV-ES, unlike PWV-BS, was higher in the subAS subgroup than in the subAS-free group after PSM (all P<0.05). For each 1 m/s increase in left, right, and bilateral mean PWV-ES, the risk of subAS increased by 23% (95% confidence interval [CI], 1.04 to 1.46), 26% (95% CI, 1.07 to 1.52), and 38% (95% CI, 1.12 to 1.72), respectively. According to ROC analyses, predictive potential was found for left PWV-ES (cutoff value=7.910 m/s, P=0.002), right PWV-ES (cutoff value=6.615 m/s, P=0.003), and bilateral mean PWV-ES (cutoff value=7.415 m/s, P<0.001), but not for PWV-BS (all P>0.05). Conclusion PWV-ES measured using ultrafast ultrasonography was significantly higher in individuals with subAS than in those without. Specific PWV-ES cutoff values showed potential for predicting an increased risk of subAS.
