Objective:To investigate the safety and efficacy of a modified radiofrequency ablation（RFA）treatment method for primary great saphenous vein varicose.Methods:Clinical data of 90 patients with primary great saphenous vein varicose treated with ultrasound-guided RFA from January 2021 to April 2024 in the Ultrasound Department of the First Affiliated Hospital of Zhengzhou University were retrospectively analyzed. Among them，45 patients were treated with traditional RFA treatment method（traditional group）and 45 patients were treated with improved RFA treatment method（improved group）. Number of punctures，operation time，foam hardener dosage，intraoperative and postoperative complications were recorded in the two groups. The preoperative and postoperative venous clinical severity score（VCSS）and chronic venous insufficiency questionnaire（CIVIQ-14）were compared. The closure rate and recurrence rate of great saphenous vein varicose were followed up and the efficacy of the two methods were analyzed.Results:The success rate of the improved group and the traditional group was 100%.The number of punctures in the improved group was less than those of the traditional group［1（1，1） vs. 2（2，3）， Z = -7.431， P<0.001］，and the operation time of the modified group was shorter than that of the traditional group［（15.89 ± 3.63）min vs.（30.91 ± 5.58）min， t=-15.145， P<0.001］，the average volume of lauryl foam was lower than that of the traditional RFA group［（7.96 ± 2.36）ml vs.（15.69 ± 2.89）ml， t=-13.892， P<0.001］. The incidence of complications was similar between the two groups，with no statistical significance（all P>0.05）. Postoperative VCSS and CIVIQ-14 scores were significantly improved compared with before（all P<0.001），with no statistical significance between the two groups（all P>0.05）. At 12 months after the operation，there was no significant difference in the closure rate of the saphenous vein between the improved group and the traditional group（ P>0.05），and the recurrence rate of varicose veins in both groups was 0. Conclusions:This modified RFA treatment method for the treatment of lower extremity varicose veins is minimally invasive，safe，and has the same efficacy as the traditional RFA treatment method. Compared with the traditional RFA treatment method，the modified RFA treatment method has the advantages of convenient operation，less puncture times and shorter operation time，and is worthy of clinical promotion.

Objective:To investigate the effects and mechanism of Shenshuaikang Enema on hypoxia/reoxygenation (H/R) NRK-52E cells; To provide references for Shenshuaikang Enema to treat AKI.Methods:The H/R-induced NRK-52E cell model was established, and control group, model group, drug-containing serum group, drug-containing blood group +p53 agonist group, p53 agonist group, p53 inhibitor group were set up. Cell viability was detected by CCK8. The cell cycle distribution in each group was analyzed using flow cytometry, while cell senescence was assessed via β-galactosidase staining. The levels of IL-6, IL-1β, and TNF-α in the cell supernatant were evaluated using ELISA. Western Blot analyses were conducted to measure the protein expressions of p53, phosphorylated p53 (p-p53), and p21.Results:Compared with model group, NRK-52E cell vitality significantly increased in the drug-containing serum group and p53 inhibitor group ( P<0.01, P<0.05), S phase and G2/M phase percentage was significantly reduced ( P<0.01), β-galactoase staining decreased ( P<0.01), the levels of IL-1β, IL-6 and TNF-α decreased ( P<0.05, P<0.01), the protein expressions of p-p53 and p21 decreased ( P<0.01). Compared with the drug-containing serum group, NRK-52E cell vitality significantly decreased in the drug-containing serum+p53 agonist group and p53 agonist group ( P<0.01), S phase and G2/M phase percentage was significantly increased ( P<0.01), β-galactoase staining increased ( P<0.01), the levels of IL-1β, IL-6 and TNF-α increased ( P<0.01), the protein expressions of p-p53 and p21 increased ( P<0.01 or P<0.05). Conclusion:The drug-containing serum of Shenshuaikang Enema may promote cell proliferation, improve cell cycle arrest, inhibit pro-inflammatory and senescence related secretory phenotypes, and inhibit cell senescence by inhibiting p53/p21 signaling pathway, so as to promote H/ R-induced NRK-52E cell damage repair.

Diabetes mellitus （DM） is a metabolic disease caused by absolute or relative insulin deficiency and reduced insulin sensitivity in peripheral cells， posing a serious threat to global health. Chronic complications arising in the later stages of DM can lead to the decline or even loss of function in multiple organs， including the eyes， heart， liver， kidneys， nerves， and feet， making them the primary cause of mortality in DM patients. Although modern medicine has made some progress in the treatment of these complications， challenges such as high costs and adverse drug reactions remain. Thus， identifying highly effective drugs with minimal adverse effects has become a top priority. Astragalus membranaceus is a shining gem in the treasure trove of Chinese medicine. Numerous studies have shown that its primary active component， astragaloside Ⅳ， possesses various biological activities， including anti-inflammatory， antioxidant， and antiviral effects， as well as benefits for cardiac and cerebral function， nerve conduction， and myocardial protection. Meanwhile， the phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） signaling pathway plays a crucial role in regulating oxidative stress， inflammatory responses， apoptosis， and autophagy. Extensive research has highlighted the significant role of this pathway in various DM complications， leading to widespread studies on its interaction with astragaloside Ⅳ. This review summarizes research findings on how astragaloside Ⅳ alleviates pancreatic cytotoxicity in DM patients by modulating the PI3K/Akt pathway. Additionally， it highlights its protective effects on basic cardiac function， inhibition of retinal cell damage， improvement of cerebral nerve dysfunction， reduction of chronic kidney and liver damage， and mitigation of neurovascular toxicity in the lower limbs. These insights provide a valuable reference for the clinical application of A. membranaceus and its active monomer， astragaloside Ⅳ， in the treatment of DM and its complications.

Primary liver cancer,particularly hepatocellular carcinoma,is one of the most common malignancies in China,and hepatectomy remains the primary curative treatment.However,the efficacy of hepatectomy is significantly limited due to the heterogeneity of liver cancer,its high recurrence rate,and the fact that most patients are diagnosed at advanced stages.In recent years,the development of precision medicine has brought new hope to liver cancer treatment,especially with notable advancements in preoperative assessment,systemic therapy,minimally invasive surgery,and personalized treatment strategies.Preoperative assessment,including imaging technologies such as three-dimensional visualization and molecular imaging,helps physicians accurately evaluate tumor characteristics and liver function,guiding the choice of treatment plan.The combined application of immunotherapy and targeted therapy has significantly improved survival rates for patients with advanced liver cancer.The strategy of combining systemic therapy with local treatment has provided new pathways for translational therapy,expanding the indications for hepatectomy.The optimal selection of patients based on tumor biological characteristics,especially molecular subtyping and liver function status,to maximize patient benefit still requires further exploration.The"seven-step"modular laparoscopic hepatectomy,by achieving scientific hepatectomy,demonstrates the clinical practice of maximizing patient benefit,further elucidating a multidisciplinary,personalized treatment model centered on surgical therapy.

Globally, over 300 million surgeries are performed each year, and more than 50% of surgeries involve patients aged 65 and older. Aging poses significant challenges to perioperative brain health, as the deterioration of brain structure and function increases susceptibility to postoperative neurological complications. Protecting perioperative brain health remains a worldwide clinical challenge. With senescence, the brain undergoes a progressive decline in homeostasis across various molecular, cellular, and regional functions. Anesthetics and surgical stimuli may accelerate the disruption of brain homeostasis and exacerbate age-related neurodegeneration. This review provides a framework for understanding how anesthesia and surgery can affect brain health in the aging population and contribute to postoperative neurological complications, with a particular focus on perioperative neurocognitive disorder.
