Diabetic kidney disease （DKD） is one of the most common microvascular complications of diabetes. Traditional Chinese medicine （TCM） plays a unique role in improving clinical symptoms， reducing proteinuria， and delaying the initiation of dialysis. Over time， scholars have held diverse views on the etiology， pathogenesis， and treatment strategies of DKD. This paper systematically reviews the etiology and pathogenesis， syndrome differentiation and treatment， and medication rules of DKD， aiming to provide a reference for clinical practice. Regarding etiology， DKD is closely related to insufficient innate endowment， improper diet， emotional disorders， overexertion， and prolonged diabetes. Its pathogenesis evolves dynamically. Specifically， early stage is characterized by Yin deficiency with dryness-heat and subtle discharge. Middle stage involves both Qi and Yin deficiency with dampness and blood stasis. Late stage presents Yin and Yang deficiency with intrinsic turbidity toxins. Blood stasis and sugar toxicity are the core pathological factors， persisting throughout the disease course and accelerating renal collateral damage and fibrosis. In terms of diagnosis and treatment， contemporary scholars advocate stage-specific treatment， emphasize the integration of prevention and therapy， recommend whole-course management， and support comprehensive TCM and Western medicine approaches. Analysis of medication rules shows that treatment consistently addresses the core principle of deficiency at the root and excess at the surface， strengthens the body while dispelling pathogenic factors， emphasizes promoting blood circulation and removing blood stasis， consolidates the kidney and astringes essence， clears Fu-organs and eliminates turbidity and toxins， invigorates the spleen， replenishes Qi， protects the stomach， and advocates treatment based on pathogenic wind. Further refinement of the academic thoughts of classical TCM masters and research into innovative pathogenesis theories and clinically effective prescriptions are needed to enhance TCM's ability to prevent and treat major clinical diseases， including DKD.

Background: Gestational diabetes mellitus (GDM) is a metabolic disorder posing significant risks to maternal and infant health, with a lack of effective early screening markers. Therefore, identifying early screening biomarkers for GDM with higher sensitivity and specificity is urgently needed. Methods: High-throughput sequencing was employed to screen for key circular RNAs (circRNAs), which were then evaluated using reverse transcription quantitative polymerase chain reaction. Logistic regression analysis was conducted to examine the relationship between clinical characteristics, circRNA expression, and adverse pregnancy outcomes. The diagnostic accuracy of circRNAs for early and mid-pregnancy GDM was assessed using receiver operating characteristic curves. Pearson correlation analysis was utilized to explore the relationship between circRNA levels and oral glucose tolerance test results. A predictive model for early GDM was established using logistic regression. Results: Significant alterations in circRNA expression profiles were detected in GDM patients, with hsa_circ_0031560 and hsa_ circ_0000793 notably upregulated during the first and second trimesters. These circRNAs were associated with adverse pregnancy outcomes and effectively differentiated GDM patients, with second trimester cohorts achieving an area under the curve (AUC) of 0.836. In first trimester cohorts, these circRNAs identified potential GDM patients with AUCs of 0.832 and 0.765, respectively. The early GDM prediction model achieved an AUC of 0.904, validated in two independent cohorts. Conclusion Hsa_circ_0031560, hsa_circ_0000793, and the developed model serve as biomarkers for early prediction or midterm diagnosis of GDM, offering clinical tools for early GDM screening.

Nigella sativa L. seeds have been traditionally utilized in Chinese folk medicine for centuries to treat vitiligo. This study revealed that the ethanolic extract of Nigella sativa L. (HZC) enhances melanogenesis and mitigates oxidative stress-induced cellular senescence and dysfunction in melanocytes. In accordance with established protocols, the ethanol fraction from Nigella sativa L. seeds was extracted, concentrated, and lyophilized to evaluate its herbal effects via 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assays, tyrosinase activity evaluation, measurement of cellular melanin contents, scratch assays, senescence-associated β-galactosidase (SA-β-gal) staining, enzyme-linked immunosorbent assay (ELISA), and Western blot analysis for expression profiling of experimentally relevant proteins. The results indicated that HZC significantly enhanced tyrosinase activity and melanin content while notably increasing the protein expression levels of Tyr, Mitf, and gp100 in B16F10 cells. Furthermore, HZC effectively mitigated oxidative stress-induced cellular senescence, improved melanocyte condition, and rectified various functional impairments associated with melanocyte dysfunction. These findings suggest that HZC increases melanin synthesis in melanocytes through the activation of the MAPK, PKA, and Wnt signaling pathways. In addition, HZC attenuates oxidative damage induced by H₂O₂ therapy by activating the nuclear factor E2-related factor 2-antioxidant response element (Nrf2-ARE) pathway and enhancing the activity of downstream antioxidant enzymes, thus preventing premature senescence and dysfunction in melanocytes.

Tumor cells use glycolysis to provide material and energy under hypoxic conditions to meet the energy requirements for rapid growth and proliferation， namely the Warburg effect. Even under aerobic conditions， tumor cells mainly rely on glycolysis to provide energy. Therefore， glucose transporter protein 1（GLUT1）， which is involved in the process of glucose metabolism， plays an important role in tumorigenesis， development and drug resistance， and is considered to be one of the important targets in the treatment of malignant tumors. In recent years， research on tumor glucose metabolism has gradually become a hot spot. It has been shown that various factors are involved in the regulation of tumor energy metabolism， among which the role of GLUT1 is the most critical. In this paper， the authors reviewed the latest research progress of GLUT1-targeted traditional Chinese medicine（TCM） active ingredient nano-delivery system in tumor therapy， aiming to reveal the feasibility and effectiveness of this system in the delivery of chemotherapeutic drugs. The GLUT1-targeted TCM active ingredient nano-delivery system can overcome the bottleneck of the traditional targeting strategy as well as the high-permeability long retention（EPR） effect. In summary， the authors believe that the GLUT1-targeted TCM active ingredient nano-delivery system provides a new strategy for targeted treatment of tumors and has a broad application prospect in tumor prevention and treatment.

Objective To investigate the intervention effect of Xuanfuhua decoction on mice with nonalcoholic steatohepatitis (NASH) induced by high-fat, high-fructose, and high-cholesterol diet. Methods A total of 32 male C57/BL6J mice were randomly divided into normal group, model group, Xuanfuhua decoction group, and obeticholic acid group, with 8 mice in each group. Since week 24 of modeling using high-fat, high-fructose, and high-cholesterol diet, each group was given the corresponding drug for intervention at a dose of 14.19 g/kg by gavage for the Xuanfuhua decoction group and 10 mg/kg by gavage for the obeticholic acid group and a volume of 20 mL/kg for gavage, once a day for 6 consecutive weeks. HE staining, oil red O staining, Sirius Red staining, and Masson staining were used to observe the pathological changes, lipid deposition, and collagen deposition of liver tissue; related kits were used to measure the serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), and glucose, as well as the content of TG and hydroxyproline (Hyp) in liver tissue; quantitative real-time PCR was used to measure the expression of genes associated with lipid metabolism, inflammation, and fibrosis in liver tissue; immunohistochemical staining was used to observe the positive expression of F4/80 and α-SMA in liver tissue. A one-way analysis of variance was used for comparison of continuous data between multiple groups, and the least significant difference t -test was used for further comparison between two groups. Results Compared with the normal group, the model group had significant increases in body weight, liver wet weight, and serum levels of AST, ALT, TC, TG, LDL-C and glucose (all P < 0.01). HE staining showed hepatocyte steatosis, a large number of fat vacuoles, hepatocyte ballooning degeneration, and inflammatory cell infiltration in liver tissue of the mice in the model group, and the model group had a significant increase in NAFLD activity score (NAS) compared with the normal group ( P < 0.01). Oil red O staining showed the deposition of a large number of red lipid droplets with different sizes in hepatocytes of the mice in the model group, and compared with the normal group, the model group had significant increases in the area percentage of oil red O staining and the content of TG in the liver ( P < 0.01). Sirius Red staining and Masson staining showed significant collagen fiber hyperplasia in the perisinusoidal area, the central vein, and the portal area in the model group, and the model group had a significant increase in the content of Hyp in liver tissue compared with the normal group ( P < 0.05). Compared with the model group, the Xuanfuhua decoction group had significant reductions in the serum levels of AST, ALT, TC, TG, LDL-C, and glucose (all P < 0.05), significant improvements in hepatic steatosis, inflammatory infiltration, lipid droplet deposition, and collagen fiber hyperplasia, and significant reductions in NAS score, area percentage of oil red O staining, and content of TG and Hyp in the liver (all P < 0.05). Compared with the normal group, the model group had significant increases in the mRNA expression levels of lipid metabolism-related genes (SREBP-1c, FASN, SCD-1, PPAR-γ, and CD36), inflammation-related genes (F4/80, TNF-α, CCL2, and CD11b), and the fibrosis-related gene α-SMA (all P < 0.05), and immunohistochemical staining showed significant increases in the positive expression of F4/80 and α-SMA ( P < 0.01). Compared with the model group, the Xuanfuhua decoction group had significant reductions in the mRNA expression levels of SREBP-1c, FASN, SCD-1, PPAR-γ, CD36, F4/80, TNF-α, CCL2, CD11b, and α-SMA in liver tissue (all P < 0.05), and immunohistochemical staining showed significant reductions in the positive expression of F4/80 and α-SMA ( P < 0.01). Conclusion Xuanfuhua decoction has a good intervention effect on mice with NASH induced by high fat, high fructose, and high-cholesterol diet and can significantly inhibit hepatic lipid deposition, inflammatory response, and liver fibrosis.

Objective:To observe the repair effect and possible mechanism of Dipsacus saponins Ⅵ on tibial fracture model rats.Methods:Thirty Sprague Dawley (SD) rats were randomly divided into model group, intervention group, and combination group, with 10 rats in each group, to establish a tibial fracture rat model using the sawing method. On the second day after surgery, the intervention group was intraperitoneally injected with 10 mg/kg of Chuanduduan saponin Ⅵ; The combination group received intraperitoneal injection of Dipsacus saponins Ⅵ 10 mg/kg and XAV939 1 mg/animal; The model group was intraperitoneally injected with 0.2 ml of physiological saline solution and 0.2 ml of dimethylsulfoxide (DMSO) solution; Once a day, continuous intervention for 14 days. After 2 to 4 weeks of intervention, Micro CT scan and X-ray scan were used to observe the fracture healing status; After 4 weeks of intervention, the wet weight of the tibia was detected; Hematoxylin eosin (HE) staining was used to observe the pathological changes of callus tissue; The Western blot method was used to detect the expression level of callus tissue β- catenin (β-catenin), p-β-catenin, glycogen synthase kinase 3β (GSK-3 β) and Runt related transcription factor 2 (Runx2) protein.Results:After 2 and 4 weeks of intervention, the bone volume fraction (BV/TV), number of trabeculae (Tb.N), Lane Sandhu score, and callus volume in the intervention group were higher than those in the model group (all P<0.05); After 2 and 4 weeks of intervention, the BV/TV, Tb.N, Lane Sandhu score, and callus volume in the combined group were lower than those in the intervention group (all P<0.05). The wet weight of the tibia in the intervention group was higher than that in the model group at 4 weeks after intervention ( P<0.05); The wet weight of the tibia in the combined group was lower than that in the intervention group ( P<0.05). The HE staining results showed that the model group had fibrous tissue hyperplasia and more bone trabeculae, but the maturity was not high and the thickening was not significant; The intervention group formed more bony callus, with orderly arrangement of bone trabeculae, partially mature, and obvious mineralization, consistent with the direction of stress; The combined group formed more cartilaginous and fibrous callus, with more mineralization at the edge of the cartilaginous callus and the formation of bone trabeculae. Abundant capillaries can be observed in the gaps. The expression level of Runx2 and p-β-catenin/β-catenin protein in callus tissue of the intervention group was higher than that of the model group, the protein expression GSK-3 β level was lower than that of the model group (all P<0.05); The expression level of Runx2 and p-β-catenin/β-catenin protein in the callus tissue of the combined group was lower than that of the intervention group; the protein expression level of GSK-3β was higher than that of the intervention group (all P<0.05). Conclusions:Dipsacus saponins Ⅵ can effectively promote fracture repair in tibial fracture model rats; It is possible to plays a role by activating the Wnt/β-catenin signaling pathway.

Hepatocellular carcinoma (HCC) is a malignant tumor with high incidence rate and mortality worldwide. However, most patients are not suitable for radical treatment at the time of first diagnosis. As one of the important schemes for the treatment of HCC, one of the most representative drug is Sorafenib, which has certain survival benefits for HCC patients at different stages. However, the drug resistance of HCC to Sorafenib greatly limits its efficacy. So far, people have found that some natural substances, experimental agents and biological macromolecules can reverse the drug resistance of HCC to Sorafenib through tumor cell microenvironment, metabolism and other mechanisms. This article will summarize the above substances and their mechanism in order to provide research ideas for the improvement of Sorafenib′s treatment program.
