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.

ObjectiveTo investigate the therapeutic effect of sitravatinib on carbon tetrachloride （CCl₄）-induced liver fibrosis in mice. MethodsA total of 30 male C57BL/6J mice， aged 8 weeks， were randomly divided into control group， CCl₄ model group， and low- （5 mg/kg）， middle- （10 mg/kg）， and high-dose （20 mg/kg） sitravatinib groups. All mice except those in the control group were given intraperitoneal injection of CCl₄ for 4 consecutive weeks to induce liver fibrosis， and since the first day of modeling， the mice in the low-， middle-， and high-dose sitravatinib groups were given sitravatinib at the corresponding dose by gavage every day. The serum levels of total cholesterol （TC）， triglyceride （TG）， and alanine aminotransferase （ALT） were measured for the mice in each group； hepatic hydroxyproline content was measured； HE staining， Masson staining， and Sirius Red staining were used to observe liver histopathological changes； quantitative real-time PCR and Western blot were used to measure the mRNA and protein expression levels of α-smooth muscle actin （α-SMA） and collagen type I alpha 1 （Col1a1） in liver tissue. The therapeutic effect of sitravatinib was assessed based on the above results. 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. ResultsCompared with the control group， the model group had significant increases in the levels of TC， TG， and ALT （all P<0.05）， and there were no significant differences in the levels of TC， TG， and ALT between the model group and the low-， middle-， and high-dose sitravatinib groups （all P>0.05）. Hepatic hydroxyproline content decreased after sitravatinib intervention， with a significant difference between the middle-/high-dose sitravatinib groups and the CCl₄ model group （both P<0.05）. Histopathological staining showed that the sitravatinib treatment groups had a reduction in collagen deposition， along with thinning and fragmentation of fibrous septa， and in the high-dose sitravatinib group， 4 mice had a fibrosis stage of S0—S1 and 2 mice had a fibrosis stage of S2—S3， suggesting a certain degree of alleviation of liver fibrosis degree compared with the CCl₄ model group （mainly S3—S4）. The measurement of related molecules showed that sitravatinib downregulated the mRNA and protein expression levels of α-SMA and Col1a1 （all P<0.05）. ConclusionSitravatinib can effectively alleviate CCl₄-induced liver fibrosis in mice， possibly by inhibiting hepatic stellate cell activation and collagen synthesis.

Stent migration is one of the common complications following transcatheter valve implantation. This study aims to design a "drum-shaped" balloon-expandable aortic valve stent to address this issue and conduct a mechanical analysis. The implantation process of the stent was evaluated using a method that combines numerical simulation and in vitro experiments. Furthermore, the fatigue process of the stent under pulsatile cyclic loading was simulated, and its fatigue performance was assessed using a Goodman diagram. The process of the stent migrating toward the left ventricular side was simulated, and the force-displacement curve of the stent was extracted to evaluate its anti- migration performance. The results showed that all five stent models could be crimped into a 14F sheath and enabled uniform expansion of the native valve leaflets. The stress in each stent was below the ultimate stress, so no fatigue fracture occurred. As the cell height ratio decreased, the contact area fraction between the stent and the aortic root gradually decreased. However, the mean contact force and the maximum anti-migration force first decreased and then increased. Specifically, model S5 had the smallest contact area fraction but the largest mean contact force and maximum anti-migration force, reaching approximately 0.16 MPa and 10.73 N, respectively. The designed stent achieves a "drum-shaped" change after expansion and has good anti-migration performance.

OBJECTIVE: To observe the effect of transcutaneous electrical acupoint stimulation (TEAS) on postoperative pain in patients undergoing modified radical mastectomy for breast cancer. METHODS: A total of 140 female patients scheduled for unilateral modified radical mastectomy for breast cancer undergoing general anesthesia were randomized into a TEAS group (70 cases) and a sham TEAS group (70 cases, 2 cases dropped out). Patients in both groups received TEAS or sham TEAS at bilateral Neiguan (PC6), Zusanli (ST36), and Danzhong (CV17), respectively, from 30 min before anesthesia induction until the end of surgery, and on 1st, 2nd, and 3rd days after surgery for 30 min a time, once a day. On 1st, 2nd, and 3rd days after surgery, the pain visual analogue scale (VAS) score was observed; on 3, 6, 12 months after surgery, the incidence rate of chronic pain was observed; before surgery, and on 1st, 3rd, and 7th days after surgery, the serum levels of tumor necrosis factor (TNF)-α, interleukin (IL)-6 and IL-10 were detected; the number of analgesia pump press, rescue analgesia, and the occurrence of adverse reaction after surgery were recorded in the two groups. RESULTS: In the TEAS group, the VAS scores on 1st and 2nd days after surgery, and the incidence rates of chronic pain on 3 and 6 months after surgery were lower than those in the sham TEAS group (P<0.05). On 1st, 3rd, and 7th days after surgery, the serum levels of TNF-α, IL-6, and IL-10 were increased compared with those before surgery in both groups (P<0.05, P<0.01); the above indexes in the TEAS group were lower than those in the sham TEAS group (P<0.05). The number of analgesia pump press and the incidence rate of rescue analgesia after surgery in the TEAS group were lower than those in the sham TEAS group (P<0.05). There was no statistically significant difference in the incidence of adverse reactions after surgery between the two groups (P>0.05). CONCLUSION TEAS can effectively improve both the postoperative acute pain and chronic pain in patients undergoing modified radical mastectomy for breast cancer, the mechanism may relate to inhibiting the inflammatory reaction.

Crohn's disease (CD) is an autoimmune disease with an unclear pathogenesis, primarily affecting the digestive tract. Perianal involvement represents a complex form of CD. Refractory proctoanal CD is a major cause of rectal resection and permanent anal sphincter dysfunction in patients. The colon pull-through with delayed anastomosis of the anal canal involves the resection of the diseased rectum and the management of the dentate line and anal canal. After the pulled-through colon has adhered to the anal canal, a revision and anastomosis are performed, aiming to preserve anal function and enhance the patients' quality of life. The specific criteria and timing for selecting this surgical approach for refractory proctoanal CD merit further discussion and investigation.

Intervertebral disc degeneration(IDD) is the pathological basis of spinal diseases. With the development and change of working and living style, IDD gradually presents the trend of younger in recent years. The effective prevention and treatment of IDD has become a hotspot in clinical research. Recent studies have shown that oxidative stress plays an important role in IDD. The disruption of reactive oxygen species balance in cells or the body leads to changes in extracellular matrix and intervertebral disc cell phenotype, which induces oxidative stress of intervertebral disc and leads to IDD. Oxidative stress can affect the development of IDD through apoptosis, autophagy, senescence and extracellular matrix of intervertebral disc. Currently, opioids and drugs for promoting blood circulation and pain relief are commonly used in clinical treatment of IDD, which can alleviate some symptoms to a certain extent, but is easy to induce gastrointestinal and other adverse reactions. Meanwhile, due to the long treatment cycle and poor patient compliance to a certain extent, which brings great difficulties to the treatment. At the same time, traditional Chinese medicine plays an important role in the treatment of IDD due to its advantages of low cost and fewer adverse reactions. With the in-depth research of modern technologies such as molecular biology and network pharmacology, it has been found that traditional Chinese medicine can intervene in the expression of oxidative stress-related functions, namely, slowing down apoptosis, autophagy and degradation of extracellular matrix, etc, to play a role in the treatment of IDD. In this paper, the role of oxidative stress in IDD and the research results on the intervention of traditional Chinese medicine in oxidative stress will be expounded, in order to provide reference for the prevention and treatment of IDD by traditional Chinese medicine.
