Diabetic nephropathy belongs to diabetic microvascular aseptic inflammation， which is the main cause of end-stage renal disease and can cause damage to the structure of glomeruli and tubulointerstitium. Pyroptosis is a potent pro-inflammatory model of programmed cell death mediated by gasdermin （GSDM） protein family， which is characterized by nuclear shrinkage， chromatin DNA fragmentation， plasma membrane rupture， cell swelling and deformation. Related studies have found that pyroptosis is closely related to the occurrence and development of diabetic nephropathy. Inhibition of pyroptosis to a certain extent can reduce diabetic renal injury， so the pathway of pyroptosis involved in the pathogenesis of diabetic nephropathy is the current research focus. The characteristics of multi-components， multi-targets and multi-pathways of traditional Chinese medicine have significant advantages in the treatment of diabetic nephropathy. Some components of traditional Chinese medicine， single traditional Chinese medicine and compound prescription of traditional Chinese medicine can improve diabetic renal injury by inhibiting pyroptosis pathway and related targets. Based on the molecular mechanism of pyroptosis， this paper clarifies the mechanism of pyroptosis in diabetic nephropathy by expounding the relationship between pyroptosis and its pathway targets and diabetic nephropathy. This paper summarizes the research status of traditional Chinese medicine in the treatment of diabetic nephropathy by interfering with related pyroptosis pathways in recent years， so as to provide perspectives and ideas for the prevention， early diagnosis， drug development and molecular treatment of diabetic nephropathy in the future.

Diabetic nephropathy （DN） is a serious chronic microvascular complication of diabetes mellitus （DM） and a major cause of end-stage renal disease （ESRD）. It is characterized by gradual and progressive decline of renal function， which eventually leads to glomerular sclerosis， interstitial fibrosis and other serious lesions. Although modern medical treatment can partially relieve the symptoms， there are limitations such as single therapeutic effect， low long-term therapeutic effect， and severe side effects. Traditional Chinese medicine （TCM）， with a wide effect range， lasting efficacy， and high safety， often exerts unique therapeutic effect in the clinical treatment of DN. Nuclear factor E₂-related factor 2 （Nrf2）， an anti-oxidative stress transcription factor， has received much attention. It can regulate multiple upstream and downstream factors such as heme oxygenase-1 （HO-1）， NAD（P）H： quinone oxidoreductase 1 （NQO1）， nuclear factor-κB （NF-κB）， NOD-like receptor thermal protein domain-associated protein 3 （NLRP3） inflammasome， glutathione peroxidase 4（GPX4）， and p62， playing a role in cell protection by intervening in different mechanisms. A large number of studies have found that TCM active ingredients and compound prescriptions can inhibit oxidative stress， inflammation， pyroptosis， apoptosis， and ferroptosis or promote autophagy by regulating the signaling pathway composed of Nrf2 and the above-mentioned related factors， thus protecting the kidney function， reducing proteinuria， alleviating kidney fibrosis， and significantly ameliorating DN. This review briefly summarized the structure and function of Nrf2， clarified the regulation mechanism of Nrf2 in DN， focused on the main studies on the intervention of DN by the effective components and compound formulas of TCM through the targeted activation of the Nrf2 signaling pathway in the past five years， and discussed the huge potential of Nrf2 signaling pathway as a target for the treatment of DN. The aim is to provide reference for the development and promotion of new drugs in clinical practice and promote the innovation and development of the treatment methods for DN in the future.

Nonalcoholic fatty liver disease （NAFLD） is one of the most common complications of type 2 diabetes mellitus （T2DM）. Cell death caused by iron-lipid disorder is a new mode of regulating programmed cell death， which is characterized by lipid peroxidation induced by the accumulation of lipid reactive oxygen species and excessive accumulation of iron ions induced by iron metabolism disorders. Among them， iron homeostasis disorder and metabolic pathway disorder are the main causes of iron-lipid disorder， which play an important role in a variety of pathological processes related to cell death. Because the liver is an important organ for iron storage and lipid metabolism， iron-lipid disorder is an ideal target for liver disease， and inhibition of iron-lipid disorder may become a new strategy for the treatment of NAFLD. However， the pathogenic relationship and mechanism between NAFLD and iron-lipid disorder have not been fully elucidated. Based on the complex molecular regulation mechanism of iron-lipid disorder， by expounding the role of iron-lipid disorder in NAFLD and its related mechanism， this paper summarizes the research status of traditional Chinese medicine on the target treatment of NAFLD in recent years， so as to provide a new perspective and point out a new direction for the treatment of NAFLD in the future.

Diabetes mellitus is a metabolic disease characterized by chronic hyperglycemia caused by absolute or relative insufficiency of insulin secretion. As the disease progresses， patients begin to suffer from diabetic nephropathy， diabetic cardiomyopathy， non-alcoholic fatty liver disease or other complications， which increase the burden on the patients. Moreover， the number of patients is increasing， which brings a heavy burden to the society. Ferroptosis is a new type of programmed cell death which has attracted wide attention in recent years. It refers to the cell death caused by the excessive accumulation of lipid peroxide under the overload of iron ions. Studies have discovered that ferroptosis exists in diabetes mellitus and its complications. Inhibiting ferroptosis can greatly slow down the occurrence and progression of diabetes mellitus and its complications. Chinese medicine， the unique medical treasure in China， acts in a multi-pathway， multi-target manner and is praised for the cheap price， low toxicity， and mild side effects. It has been widely used in the treatment of diabetes mellitus and its complications and has demonstrated definite therapeutic effects， bringing the good news for the majority of patients. The regulation of ferroptosis by Chinese medicine may be a new direction for the treatment of diabetes mellitus and its complications in the future. This paper briefly describes the mechanism of ferroptosis， explores the relationship of ferroptosis with diabetes mellitus and its complications， summarizes the research status of Chinese medicine interventions， and puts forward suggestions， aiming to provide a reference for further research on the treatment of diabetes mellitus and its complications with Chinese medicine.

Objective:To investigate the enrollment scale and distribution of Master's Degree in Pediatrics programs in China, and to provide a reference for promoting pediatric education and disciplinary development.Methods:Data on colleges and universities authorized to award Master's Degree in Pediatrics in 2023 were collected, sorted, and analyzed for the number, structure, distribution, and enrollment scale and direction of these institutions using descriptive statistics.Results:Among the 117 clinical medicine academic master's degree programs in China, 72 enroll pediatric academic master's degree candidates, with an enrollment of 260 students. Among the 120 master's degree programs in clinical medicine, 104 enroll professional master's degree candidates, enrolling 1 195 students. Enrollment is mainly concentrated in East China, "non-double first-class" colleges and universities, medical colleges and universities with subject level B, and enrollment is carried out in the direction of secondary disciplines.Conclusions:The number of colleges and universities authorized to award Master's Degree in Pediatrics was small, and the distribution of these colleges and universities was unbalanced. The enrollment scale was small and the orientation of Professional Master's Degree was not reasonable. Some colleges and universities were authorized to award Master's Degree in Pediatrics, but did not enroll any students. It is suggested to increase the number of colleges and universities authorized to award Master's Degree in Pediatrics and strengthen the staffing of pediatric departments. The aim is to expand the enrollment scale of candidates for Master's Degree in Pediatrics, improving the differential training of candidates for Academic Master's Degree and Professional Master's Degree, and attach importance to the construction of pediatrics.

Diabetic nephropathy （DN）， as one of the common chronic microvascular complications of diabetes， has become the main cause of renal failure in end-stage renal disease in China， increasing the risks of renal dialysis and kidney transplantation in diabetes patients. It is the leading cause of death in people with diabetes. The latest research on DN has focused on the gene level. microRNAs （miRNAs） are a family of endogenous accessible short-chain non-coding RNA molecules. By acting on a particular target， they activate or inhibit its mediated signaling pathways and related molecules， playing an important role in the occurrence and development of DN. They have become microeconomic factors for the prevention and treatment of DN. Traditional Chinese medicine （TCM） has a long history in the diagnosis and treatment of DN and has unique advantages such as significant curative effect and few side effects. A large number of studies have proved that TCM can target miRNA to affect multiple signaling pathways， participate in the regulation of inflammatory response， pyroptosis， mesenchymal transdifferentiation， and other pathological changes， and delay the further development of DN. Therefore， this study discusses the biogenesis mechanism of miRNA and its action mechanism in disease-related signaling pathways based on TCM diagnosis and treatment approaches from the perspective of miRNA， and summarizes the effect of TCM targeting miRNA on the disease-related signaling pathways and on DN. Thus， this study is expected to provide a theoretical reference for exploring the progress of TCM intervention in DN from the perspective of genes.

ObjectiveTo observe the effect of Hedysari Radix polysaccharide （HRP） on the Janus kinase 2 （JAK2）/signal transducer and activator of transcription protein 3 （STAT3） signaling pathway in diabetic nephropathy db/db mice. MethodFifty db/db mice were randomly divided into model group， irbesartan group （irbesartan suspension， 22.75 mg·kg^-1）， and high-， medium-， and low-dose HRP groups （HRP suspension， 200， 100， 50 mg·kg^-1） according to the body weight， with 10 mice in each group. Another 10 C57BL/6 mice were assigned to the normal group. The mice were treated with corresponding drugs by gavage， while those in the normal group and the model group received distilled water at 5 mL·kg^-1. The mice in the six groups were administered once a day by gavage for 12 consecutive weeks. The uric acid （UA）， triglycerides （TG）， and total cholesterol （TC） were detected. Periodic acid-Schiff （PAS） staining and Masson staining were used to observe the pathological changes in kidney tissues. Western blot and Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） were used to detect the protein and mRNA expression levels of JAK2， STAT3， suppressor of cytokine signaling 3 （SOCS3）， and tumor necrosis factor-α （TNF-α） in the kidney. ResultAfter 12 weeks of treatment， compared with the normal group， the model group showed significant pathological ultrastructural changes in kidney tissues and increased UA， TG， and TC levels （P<0.01）. Compared with the model group， the high- and medium-dose HRP groups and the irbesartan group showed improvement in pathological ultrastructure of kidney tissues and reduced UA， TG， and TC levels （P<0.05， P<0.01）. Compared with the normal group， the model group showed a decrease in SOCS3 protein and mRNA expression levels and an increase in JAK2， STAT3， and TNF-α protein and mRNA expression levels （P<0.01）. Compared with the model group， the high- and medium-dose HRP groups and the irbesartan group showed an increase in SOCS3 protein and mRNA expression levels and a decrease in JAK2， STAT3， and TNF-α protein and mRNA expression levels （P<0.05， P<0.01）. ConclusionHRP can alleviate renal damage in diabetic nephropathy to a certain extent， and its mechanism may be related to the inhibition of the activation of the JAK2/STAT3 signaling pathway.
