Objective To elucidate the molecular mechanism of sirtuin-3 (SIRT3) in regulating mitochondrial biogenesis in human renal tubular epithelial cells. Methods Cells were stimulated with different concentrations of H₂O₂ and divided into four groups: control (NC), 50 μmol/L H₂O₂, 110 μmol/L H₂O₂ and 150 μmol/L H₂O₂. SIRT3 protein expression was then measured. SIRT3 was knocked down with siRNA, and cells were further assigned to five groups: control (NC), negative-control siRNA (NCsi), SIRT3-siRNA (siSIRT3), NCsi+H₂O₂, and siSIRT3+H₂O₂. After 24 h, cellular adenosine triphosphate (ATP) and mitochondrial superoxide anion (O₂•⁻) levels were determined, together with mitochondrial expression of SIRT3, peroxisome proliferator-activated receptor γ coactivator-1α (PGC-1α), nuclear respiratory factor 1 (NRF1), mitochondrial transcription factor A (TFAM), superoxide dismutase 2 (SOD2), acetylated-SOD2 and adenosine monophosphate activated protein kinase α1 (AMPKα1). Results The 110 and 150 μmol/L H₂O₂ decreased SIRT3 protein (both P<0.05). ATP and mitochondrial O₂•⁻ did not differ between NC and NCsi groups (both P>0.05). Compared to the NCsi group, the siSIRT3 group exhibited elevated O₂•⁻ level, decreased SIRT3 protein and increased expression levels of SOD2 and acetylated SOD2 protein (all P<0.05). Compared to the NCsi group, the NCsi+H₂O₂ group exhibited decreased cellular ATP levels, elevated mitochondrial O₂•⁻ levels, and reduced protein expression levels of SIRT3, SOD2, TFAM, AMPKα1, PGC-1α and NRF1 (all P<0.05). Compared with the siSIRT3 group, the siSIRT3+H₂O₂ group showed a decrease in cellular ATP levels, an increase in mitochondrial O₂•⁻ levels, a decrease in SIRT3, SOD2, TFAM, AMPKα1, PGC-1α and NRF1 protein expression levels and a decrease in acetylated SOD2 protein expression levels (all P<0.05). Compared with the NCsi+H₂O₂ group, the siSIRT3+H₂O₂ group showed a decrease in cellular ATP levels, an increase in mitochondrial O₂•⁻ levels, a decrease in SIRT3, AMPKα1, PGC-1α and NRF1, TFAM protein expression levels, and an increase in SOD2 and acetylated SOD2 protein expression levels (all P<0.05). Conclusions SIRT3 promotes mitochondrial biogenesis in tubular epithelial cells via the AMPK/PGC-1α/NRF1/TFAM axis, representing a key mechanism through which SIRT3 ameliorates oxidative stress-induced mitochondrial dysfunction.

ObjectiveTo explore the medication patterns of Professor Zhang Farong in treating type 2 diabetes mellitus （T2DM） and the clinical efficacy of his core prescription. MethodsClinical case records of T2DM treated by Professor Zhang Farong were collected to establish a prescription database. Frequency statistics， visual analysis， and factor analysis were employed to investigate the characteristics and principle of the prescriptions， and a core prescription was derived. A randomized controlled trial was conducted， enrolling 60 T2DM patients with the dampness-heat syndrome. The patients were allocated into an observation group （core prescription + metformin） and a control group （metformin alone）， with both groups undergoing a 12-week treatment course. Changes in TCM symptom scores， glucose metabolism indicators ［fasting plasma glucose （FPG）， 2-hour postprandial blood glucose （2 hPG）， and glycated hemoglobin （HbA1c）］， pancreatic function indicators ［fasting C-peptide （FCP）， 2-hour postprandial C-peptide （2 hCP）， and area under the C-peptide curve （AUCcp）］， and lipid profiles were measured before and after treatment. The adverse reactions were observed and recorded. ResultsA core prescription named modified Gegen Qinlian Decoction was formulated， comprising Puerariae Lobatae Radix， Coptidis Rhizoma， Scutellariae Radix， Astragali Radix， Lycii Cortex， Mori Cortex， Jineijin Endothelium Corneum Gigeriae Galli， Rehmanniae Radix Praeparata， Atractylodis Rhizoma， Polygonati Rhizoma， and Pogostemonis Herba. The clinical trial results showed that both groups had significantly decreased FPG， 2 hPG， and HbA1c （P0.05）， and the observation group outperformed the control group in recovering the level of HbA1c （P0.05）. After treatment， both groups had declined TCM symptoms scores （P0.05）， and the declines in the observation group were larger than those in the control group （P0.05）. After treatment， the TC and LDL-C levels declined in the observation group （P 0.05）， while the lipid levels showed a decreasing trend with no statistically significant difference in the control group. After treatment， both groups showed increases in FCP and AUCcp （P0.05）， and the 2 hCP in both groups presented a recovering trend with no statistically significant difference. There was no statistically significant difference in the incidence of adverse reactions between the two groups. ConclusionModified Gegen Qinlian Decoction embodies Professor Zhang Farong's academic philosophy of treating consumptive thirst by tonifying the spleen and kidney， replenishing Qi and Yin， clearing deficiency and heat， unblocking stasis in collaterals， and addressing both deficiency and stasis. The combination of the core prescription with metformin alleviates clinical symptoms in T2DM patients with the dampness-heat syndrome， demonstrating potential effects in restoring pancreatic islet function， regulating blood glucose， and improving lipid profiles. It serves as a therapeutic option for T2DM in the patients with the dampness-heat syndrome under syndrome differentiation， meriting broader clinical application.

Allergen-specific Immunotherapy (AIT) is currently the only allopathic treatment capable of modifying the natural course of immunoglobulin E (IgE)-mediated allergic diseases. Currently, there is a lack of recognized clinical markers for evaluating and predicting the efficacy of AIT, and some biological markers may have some potential for application. This article will summarize the currently known indicators for evaluating and predicting the therapeutic effects of AIT, with the aim of providing assistance in evaluating and monitoring the efficacy of AIT.

The prevalence of allergic diseases is on the rise,posing a significant global health challenge.Allergen specific immunotherapy(AIT)is the only treatment capable of altering the natural course of allergic diseases,offering long-term efficacy and the potential to prevent disease progression.However,its widespread application is hindered by factors such as lengthy treatment duration,adverse reactions,and patient compliance issues.In recent years,biologics targeting type 2 inflammatory pathways have played a crucial role at various stages of different allergic diseases.Research indicates that for patients with moderate to severe allergic diseases,using biologics during or prior to AIT can significantly enhance the safety of AIT,reduce the time required to reach maintenance doses,and markedly improve symptom scores.This article elucidates the synergistic mechanisms and recent advancements in the combined application of biologics and AIT in the treatment of allergic diseases.The aim is to provide a reference for the standardized treatment of allergic diseases.
