Diabetic kidney disease （DKD）， a common complication of diabetes mellitus， is a leading global cause of end-stage renal disease （ESRD）. Current therapeutic strategies primarily focus on symptomatic management but exhibit limited efficacy in halting disease progression to ESRD， and some drugs carry non-negligible toxic side effects. Traditional Chinese medicine （TCM） has a long history in treating DKD， with single TCM and TCM compounds demonstrating unique advantages in multi-target， multi-pathway， and multi-effect therapeutic interventions. Tripterygium wilfordii （TW）， known for its effects in promoting blood circulation， dredging collaterals， dispelling wind， removing dampness， reducing swelling， and alleviating pain， contains bioactive components such as Tripterygium glycosides （TWG）， triptolide （TPL）， tripdiolide （TPD）， and celastrol （CEL）. The active ingredients possess various functions， including regulating immune-inflammatory balance， ameliorating renal fibrosis and glomerulosclerosis， combating oxidative stress， protecting podocytes， and improving glucose and lipid metabolism， all of which play a significant role in the treatment of DKD. This review summarized the mechanisms underlying the therapeutic effects of T. wilfordii and its active ingredients on DKD， aiming to provide insights for clinical management and novel drug development of DKD.

Nephrotic syndrome （NS） is a glomerular disease characterized by massive proteinuria， hypoalbuminemia， edema， and hyperlipidemia. Tripterygium wilfordii exhibits remarkable efficacy in the prevention and treatment of renal diseases； however， its hepatotoxicity， nephrotoxicity， and other factors limit its clinical application. This article systematically reviews the mechanisms of pharmacological effects and detoxification of T. wilfordii and its active ingredients in the treatment of NS. The results show that the main active components of T. wilfordii include tripterygium glycosides， triptolide， and triptriolide， etc. T. wilfordii and its active ingredients exert significant renal protective effects by protecting glomerular podocytes， repairing the glomerular filtration barrier， regulating abnormal immune and inflammatory responses， inhibiting oxidative stress injury， and blocking renal fibrosis， thereby effectively reducing proteinuria， improving renal function， and lowering the recurrence rate of NS. Traditional Chinese medicine compatibility （e.g. T. wilfordii combined with Lysimachia christinae ， Cuscuta chinensis ethanol extract， and Paeonia lactiflora ， respectively） can regulate anti-inflammatory and antioxidant levels and optimize drug metabolic pathways. Combined with modern preparation technologies （e.g.， triptolide self-microemulsion drug delivery system）， these strategies can effectively antagonize the hepatotoxicity， nephrotoxicity， and other factors of T. wilfordii .

Immunoglobulin A nephropathy （IgAN） is a common primary glomerular disease and a frequent cause of chronic renal failure. Tripterygium wilfordii is a traditional Chinese herbal medicine， which possesses the effects of promoting blood circulation， relieving swelling and pain， and dispelling wind and dampness. Modern pharmacological studies have shown that T. wilfordii multiglucoside exhibit anti-inflammatory and immunomodulatory effects， inhibit mesangial cell proliferation， protect podocytes， ameliorate endothelial cell injury， and regulate gut microbiota disturbances. Triptolide also possesses anti-inflammatory and immunomodulatory properties， suppresses mesangial cell proliferation， and protects podocytes. Celastrol demonstrates anti- inflammatory and immunomodulatory functions as well as the ability to improve endothelial cell damage. Through these mechanisms， T. wilfordii and its active components can play a role in alleviating clinical symptoms and delaying disease progression in the treatment of IgAN. Future research should focus on in-depth analysis and mechanistic investigation of these active ingredients， promote high-quality clinical studies， systematically evaluate the synergistic effects among them， and emphasize strategies for reducing toxicity and enhancing efficacy， thereby providing more comprehensive and reliable evidence-based foundations for the clinical treatment of IgAN.

OBJECTIVE To evaluate the efficacy and safety of rituximab （RTX） in the treatment of children with refractory nephrotic syndrome （RNS） based on the real world by meta-analysis. METHODS A systematic search was conducted on CNKI， Wanfang， VIP， PubMed， Embase， Web of Science， the Cochrane Library， and CINAHL databases to strictly screen the literature and evaluate their quality. A meta-analysis was performed on the extracted literature data using R 4.2.2 and RStudio software. RESULTS A total of 26 real-world studies were included in this study， involving 996 children with steroid-dependent nephrotic syndrome/frequente-relapse nephrotic syndrome （SDNS/FRNS） and 205 children with steroid-resistant nephrotic syndrome （SRNS）. The results of the meta-analysis showed that the complete remission （CR） rate of RTX treatment for RNS was 46% （95%CI： 37%-56%）， the partial remission （PR） rate was 22% （95%CI： 14%-31%）， and the discontinuation rate was 35% （95%CI： 25%-44%）. The results of subgroup analysis showed that the CR rate of RTX treatment in SDNS/FRNS children was 49% （95%CI： 37%-62%）， PR rate was 25% （95%CI： 0-50%）， discontinuation rate was 41% （95%CI： 29%-52%）； the CR rate in SRNS children was 42% （95%CI： 27%-56%）， PR rate was 22%（95%CI： 12%-32%）， discontinuation rate was 21% （95%CI： 4%-38%）. The recurrence rate in children with SDNS/FRNS was 39% （95%CI： 21%-57%） within 1 year or less， 18% （95%CI： 18%-98%） in 2 years and more. As for safety， the majority of adverse reactions were mild infusion reactions， with an incidence of 13% （95%CI： 8%-22%）. Sensitivity analysis suggested that the results were robust. There was publication bias in mild infusion 20210908-BZ-CACM） reaction rate. CONCLUSIONS RTX is effective and safe in the treatment of RNS in children.

OBJECTIVE To evaluate the efficacy and safety of belimumab in the treatment childhood-onset systemic lupus erythematosus （cSLE）， and to provide evidence-based references for clinical medication. METHODS Randomized controlled trials （RCTs） about belimumab or belimumab combined with hormone or belimumab combined with hormone and traditional drugs （test group） compared with placebo or hormone or traditional drugs or traditional drugs combined with hormone （control group） were collected by computer searching CNKI， Wanfang data， VIP， SinoMed， PubMed， Embase， Web of Science and the Cochrane Library； the search deadline was from the establishment of the databases to April 9th， 2023. After screening the literature and extracting the data， the quality of the included literature was evaluated by using the bias risk assessment tool recommended by Cochrane system evaluation manual 5.1.0； meta-analysis and sensitivity analysis were conducted by using RevMan 5.4 software. RESULTS A total of 510 children were included in 7 RCTs. Results of the meta-analysis showed that the clinically effective rate of test group was significantly better than the control group [OR＝6.16， 95%CI （2.23， 17.00）， P＝0.000 4]. There were no statistically significant differences in SLE disease activity index （SLEDAI） [MD＝－1.73， 95%CI （－3.50， 0.05）， P＝0.06]， the incidence of adverse drug reactions [OR＝0.72， 95%CI （0.43， 1.19）， P＝0.02]， complement C3 levels [MD＝0.12， 95%CI （－0.06， 0.30）， P＝0.18]， complement C4 levels [MD＝0.08，95%CI （－0.07，0.24）， P＝0.30] or the response rate of SLE responder index 4 [OR＝1.52， 95%CI （0.94，2.44）， P＝0.09] between 2 groups. The results of sensitivity analysis showed that when SLEDAI， the complement C3 levels and complement C4 levels were used as indicators， the results obtained in this study were robust. CONCLUSIONS The efficacy of belimumab in the treatment of cSLE is good， and its safety is comparable to the basic treatment.

Objective To select the aptamer to an extracellular soluble fragment of recombinant human TGF-? receptor Ⅱ (TGF-? RⅡ) in order to antagonize TGF-? effectively by using systematic evolution of ligants by exponential enrichment (SELEX). Methods Initial random RNA library was transcripted in vitro from ssDNA 5′-TAATACGACTCACTATAGGGAGGACGATGCGG-N60-CAGACGACTCCCCGA-3′; rhTGF-? RⅡ was used as target protein. Totally,selection of 8 times was carried out in SELEX experiment. Membrane binding assay was performed to detect the evolution of enriched RNA library; Electrophoretic mobility shift assay (EMSA) was done to determine the affinity between the selected nucleic acid sequence and TGF-? RⅡ. Results Evolution of the enriched RNA library along the increased affinity to TGF-? RⅡ was observed with the development of selection. Two types of dominant sequences were isolated and named as sequence A and sequence B. In membrane binding assay,both sequences A and B showed obvious affinity to TGF-? RⅡ. However,no retarded bands were seen in EMSA. Conclusion The affinity of sequences A and B to TGF-? RⅡ is beyond satisfaction. However,possible sequences with improved affinity to TGF-? RⅡ can be selected by post-SELEX on the basis of candidate sequences A and B.
