Eight weeks after initiating drug administration, all rats were sacrificed, and samples of urine, blood, and kidney tissue were collected for examination. The DKD rat model's IR and podocyte EMT parameters were examined, covering general health, body weight (BW), kidney weight (KW), biochemical parameters and IR markers, protein expression in the IRS 1/PI3K/Akt pathway, foot process morphology and GBM thickness, expressions of EMT markers and structural molecules in the slit diaphragm, and glomerular histomorphological characteristics. Both TFA and ROS treatments led to improvements in the general condition, biochemical parameters, renal appearance, and body weight (KW) of DKD model rats. The ameliorative influence of TFA and ROS was equal across body weight, urinary albumin-to-creatinine ratio, serum creatinine, triglyceride levels, and KW. Furthermore, enhancing IR indicators was achievable by both approaches, yet ROS exhibited a more pronounced impact on improving fast insulin (FIN) and homeostasis model assessment of insulin resistance (HOMA-IR) compared to TFA. Flexible biosensor From a third perspective, both strategies exhibited the ability to increase the expression levels of proteins within the IRS1/PI3K/Akt signaling cascade, showing diverse extents of glomerulosclerosis amelioration, and their curative effects were consistent. Genetics behavioural Finally, the potential of both treatments in reducing podocyte harm and epithelial-mesenchymal transition (EMT) was notable, with TFA showing a superior performance compared to reactive oxygen species (ROS). This study's findings support the hypothesis that IR, acting through diminished IRS1/PI3K/Akt pathway activity in the kidney, might contribute to podocyte EMT and glomerulosclerosis in DKD. Similar to the effects of reactive oxygen species (ROS), TFA's ability to inhibit podocyte epithelial-mesenchymal transition (EMT) in diabetic kidney disease (DKD) involves activating the IRS1/PI3K/Akt signaling cascade, enhancing insulin sensitivity. This may be one scientific interpretation of TFA's impact on DKD. This study offers pioneering pharmacological support for the future development and application of TFA in diabetic complications.

This research investigated the impact of multi-glycosides of Tripterygium wilfordii (GTW) on renal injury within diabetic kidney disease (DKD) rats, exploring the Nod-like receptor protein 3 (NLRP3)/cysteine-aspartic acid protease-1 (caspase-1)/gasdermin D (GSDMD) pyroptosis pathway and the underlying mechanisms. Forty male SD rats were randomly grouped; eight rats were placed in the normal control group, and thirty-four in the model group. To induce diabetic kidney disease (DKD) in rats, the modeling group utilized a high-sugar, high-fat dietary intake coupled with a single intraperitoneal streptozotocin (STZ) injection. Following the successful completion of the modeling process, participants were randomly assigned to one of three groups: the model group, the valsartan (Diovan) group, or the GTW group. The groups of normal and model individuals were treated with normal saline. Meanwhile, the valsartan and GTW groups, respectively, received valsartan and GTW for six weeks. The biochemical analysis determined the levels of blood urea nitrogen (BUN), serum creatinine (Scr), alanine aminotransferase (ALT), albumin (ALB), and 24-hour urinary total protein (24h-UTP). JHU-083 Renal tissue's pathological characteristics were observable through the application of hematoxylin and eosin (H&E) staining. Interleukin-1 (IL-1) and interleukin-18 (IL-18) serum concentrations were determined through the application of enzyme-linked immunosorbent assays (ELISA). To evaluate the expression of proteins and genes related to the pyroptosis pathway in renal tissue, Western blot and RT-PCR techniques were respectively used. The model group's renal function was significantly impaired compared to the normal group, manifesting as elevated BUN, Scr, ALT, and 24-hour urinary total protein (24h-UTP). Further, the model group displayed elevated serum levels of IL-1 and IL-18 (P<0.001), along with decreased serum albumin (P<0.001) and severe pathological kidney damage. Remarkably, high levels of NLRP3, caspase-1, and GSDMD protein and mRNA were observed in the renal tissue (P<0.001). Significantly lower levels of BUN, Scr, ALT, and 24-hour urinary total protein (24h-UTP) were found in the valsartan and GTW groups compared to the model group. These groups also exhibited reduced serum levels of IL-1 and IL-18 (P<0.001), with elevated albumin levels (ALB, P<0.001). Subsequently, pathological kidney damage was reduced, and the renal tissue exhibited diminished protein and mRNA levels of NLRP3, caspase-1, and GSDMD (P<0.001 or P<0.005). Renal tissue inflammation and damage in DKD rats may be mitigated by GTW through its impact on reducing the expression of NLRP3/caspase-1/GSDMD, effectively controlling pyroptosis.

Due to its status as a major microvascular complication of diabetes, diabetic kidney disease stands as the leading cause of terminal kidney failure. The significant pathological features of this condition encompass epithelial mesenchymal transition (EMT) in the glomerulus, podocyte apoptosis and autophagy, and the compromised structure of the glomerular filtration barrier. In physiological contexts, the TGF-/Smad signaling pathway, involved in apoptosis, proliferation, and differentiation, is a target of precise regulation orchestrated by numerous mechanisms. Current studies frequently identify the TGF-/Smad signaling pathway as a fundamental aspect in the onset of diabetic renal disease. The multifaceted nature of Traditional Chinese Medicine, characterized by its multi-component, multi-target, and multi-pathway mechanisms, presents potential advantages in managing diabetic kidney disease. Traditional Chinese medicine's extracts, formulations, and compound prescriptions may help reduce renal injury in diabetic kidney disease by modulating the TGF-/Smad signaling pathway. This study elucidated the TGF-/Smad signaling pathway's mechanism in diabetic kidney disease by detailing the connection between key pathway targets and the disease itself, and reviewed recent advancements in traditional Chinese medicine's approach to diabetic kidney disease treatment through TGF-/Smad pathway intervention, ultimately providing a foundation for future drug research and clinical management.

The connection between disease and syndrome is under rigorous scrutiny as part of the ongoing integration of traditional Chinese and Western medical practices. Treatment modalities for disease-syndrome complexes depend heavily on the focal point. This can manifest as diverse therapies for the same disease, yet contingent upon the specific syndrome, or a single treatment method for different diseases, unified by the syndrome. This further translates to different therapies for the same syndrome, yet customized by the varied diseases. The mainstream model results from the combination of traditional Chinese medicine's syndrome identification and core pathogenesis with modern medicine's di-sease identification. Despite this, current research into the intersection of disease and syndrome, and their core mechanisms, frequently emphasizes the variability between disease and syndrome, and the disconnection between syndromes and their therapies. Consequently, the investigation championed the research concept and framework of core formulas-syndromes (CFS). The principle of formula-syndrome correspondence underpins CFS research, which strives to expand understanding of core disease pathogenesis by collecting core formulas and syndromes. Studies concerning diagnostic criteria for formulas, patterns of formula distribution connected to diseases and their syndromes, the evolution of medicinal syndromes as related to formulas and syndromes, formula combination principles based on the relationship between formulas and syndromes, and the dynamic shifts in formula-syndrome correlations are part of ongoing research. The investigation of diagnostic criteria for formula indications draws upon the wisdom of ancient medical texts, the practical knowledge of clinical experience, and meticulous review of patient records. This research further employs expert consultations, factor analytic procedures, and cluster analyses to explore diagnostic information on diseases, symptoms, physical signs, and their associated pathophysiological processes. Investigating the distribution of disease formulas and syndromes involves compiling specific types of formulas and syndromes for diseases by analyzing clinical and literary sources, which relies on established diagnostic criteria for the indications of formulas. A study of medicinal syndromes' progression aims to define the rules that govern their manifestation, utilizing historical and clinical case studies. Formula combinations in medical treatments frequently show a core prescription associated with several other components, recurring regularly. A continuous transformation and alteration of formulas and syndromes, representing the dynamic evolution in disease progression, is impacted by variations in time and location. The CFS framework encourages the unification of disease, syndrome, and treatment, thereby bolstering the research model's focus on integrated disease and syndrome.

Zhang Zhong-jing's Treatise on Cold Damage, composed during the Eastern Han dynasty, contains the first mention of Chaihu Jia Longgu Muli Decoction. This renowned medical classic initially employed it in the care of Shaoyang and Yangming syndromes. Based on the current understanding of pathophysiological mechanisms, this study presented a re-evaluation of the traditional Chaihu Jia Longgu Muli Decoction. Original records of “chest fullness,” “annoyance,” “shock,” “difficult urination,” “delirium,” and “heavy body and failing to turn over” exhibit a substantial pathophysiological foundation rooted in the dysfunction of the cardiovascular, respiratory, nervous, and mental systems. For epilepsy, cerebral arteriosclerosis, cerebral infarction, and other cerebrovascular diseases, this formula is widely employed. Its application further encompasses hypertension, arrhythmia, and other cardiovascular diseases; insomnia, constipation, anxiety, depression, cardiac neurosis; and other acute and chronic conditions, including those in psychosomatic medicine.
