Objective To examine the phenotypic characteristics of Ecto-5'-nucleotidase(NtSe/CD73)gene knockout mice in restenosis of blood vessels after vein transplantation so as to identify potential targets for early diagnosis and drug treatment of vascular restenosis after clinical coronary artery bypass surgery.Methods CD73 gene knockout mice aged 8-10 weeks were used as the experimental group,and the littermate wild-type mice were used as the control group.Using the inferior vena cava of mice as a donor,we transplanted to the right carotid artery of allogeneic mice with a trocar method to establish a mouse inferior vena cava carotid artery vascular transplantation model.At the 4th week post-model establishment,we systematically evaluated the patency of the transplanted blood vessels,the formation of the vascular intima,the proliferation of the media,the morphology of the elastin layer,and the expression of inflammatory factors.The vascular smooth muscle cells(VSMCs)from the inferior vena cava of mice were isolated in vitro,and the migration and proliferation were assessed with CD73 inhibitor adenosine 5'-(alpha,beta-methylene)diphosphate(APCP).Results In CD73 knockout mice,neointima formation was impaired,the elastic fiber layer was disrupted and lost,and medial smooth muscle cells proliferated more actively.These changes ultimately led to decreased vascular wall elasticity and increased blood flow resistance.The immunohistochemical staining results suggest that in CD73 gene knockout mice the transplanted vein tissue showed extensive infiltration of Mac-2 positive macrophages,and the expression of cytokines interleukin-1 β(IL-1 β),IL-6,and transforming growth factor β(TGF-β)was significantly increased.CD73 deficiency exacerbated inflammatory responses and vascular remodeling in venous tissues.Scratch wound healing and cell proliferation assays revealed that CD73 inhibition promoted VSMCs proliferation,yet concurrently impaired their migratory capacity.Conclusion Knockout of the CD73 gene exacerbates vascular remodeling and inflammatory response in vein grafts,offering crucial insights for the precise diagnosis and targeted treatment of patients with CD73 gene defects undergoing coronary artery bypass surgery in clinical practice.

ObjectiveTo investigate the feasibility and safety of endoscopic retrograde cholangiopancreatography （ERCP） combined with oral cholangiopancreatography in the treatment of major duodenal papilla gallbladder polyps. MethodsA retrospective analysis was performed for the clinical data of eight patients with choledocholithiasis and gallbladder polyps who underwent ERCP and combined with oral cholangiopancreatography for major duodenal papilla cholecystectomy in Center of Digestive Endoscopy， Jilin People’s Hospital， from May 2022 to June 2024， and related data were collected， including the success rate of surgery， the technical success rate of gallbladder polyp removal， the superselective method of cystic duct， the time of operation， the time of gallbladder polyp removal， and surgical complications. ResultsBoth the success rate of surgery and the technical success rate of gallbladder polyp removal reached 100%， and of all eight patients， three patients used guide wire to enter the gallbladder under direct view， while five patients received oral cholangiopancreatography to directly enter the gallbladder. The time of operation was 51.88±12.34 minutes， and the time of gallbladder polyp removal was 23.13±10.94 minutes. The diameter of gallbladder polyp was 2‍ ‍—‍ ‍8 mm， and pathological examination showed inflammatory polyps in three patients， adenomatous polyps in one patient， and cholesterol polyps in four patients. There were no complications during or after surgery. The patients were followed up for 2‍ ‍—‍ ‍27 months after surgery， and no recurrence of gallbladder polyp was observed. ConclusionOral cholangiopancreatography is technically safe and feasible in endoscopic major duodenal papilla cholecystectomy.

OBJECTIVE To study the anti-ulcerative colitis(UC) effect of Sargentodoxae Caulis and explore its mechanism. METHODS The UC mice model induced by dextran sodium sulfate was used to evaluate the anti-UC effect of Sargentodoxae Caulis. The ingredients of Sargentodoxae Caulis were obtained according to the CNKI and PubMed website, component targets were screened by SwissTargetPrediction database, GEO gene chip was used to extract UC differential genes, then a network of "ingredients-targets-disease" of the Sargentodoxae Caulis was constructed. After screening the core targets, protein interaction and cluster analysis, biological process and pathway enrichment analysis were performed, and the reliability of network analysis was preliminarily verified by molecular docking and literatures. RESULTS Sargentodoxae Caulis could significantly improve the disease activity index score, colon shortening and colonic histopathological changes of UC mice, and had a good anti-UC effect. The network analysis found that the core components of the anti-UC of Sargentodoxae Caulis include (+)-Dihydroxyurearetic acid, Isorhaponigenin and Pinosylvin, and 63 core targets, such as EGFR, STAT1 and LCK, regulating PI3K-Akt signal pathway and cancer proteoglycan and other related signal pathways of immune anti-inflammatory and anti-cancer, and it could affect the biological processes such as amino acid modification, kinase activity regulation, cell reaction and oxidative stress to treat UC. Molecular docking and literature showed that the constructed network had high reliability. CONCLUSION Sargentodoxae Caulis has a good anti-UC effect, and its mechanism may be closely related to the regulation of intestinal immune inflammation and cell proliferation, differentiation and migration. It has the characteristics of multi-component, multi-target and multi-way.

Objective:To analyze the clinical value of indocyanine green (ICC) fluorescence imaging in Mirizzi syndrome type Ⅱ-Ⅲ laparoscopic cholecystectomy (LC).Methods:A retrospective analysis was performed on 80 patients diagnosed with Mirizzi syndrome types Ⅱ-Ⅲ who underdoing LC in Affiliated Hospital of Liaoning University of Traditional Chinese Medicine from October 2018 to February 2022, including 32 males and 48 females, aged (63.5±6.9) years. Patients were divided into two groups based on whether ICG fluorescence imaging technology was used, the control group ( n=38) that patients were treated with conventional LC and the experimental group ( n=42) patients were treated with LC guided by ICG fluorescence imaging. In the experimental group, the extrahepatic bile duct was identified by ICG fluorescence imaging during LC, and ICG was injected intraoperally to determine the reserved blood flow of gallbladder flap for fluorescence imaging and determine the resection line. Operation time, intraoperative blood loss, conversion rate of laparotomy and postoperative complications (bile leakage, incision infection, etc.) were compared between the two groups. Intraoperative fluorescence imaging and determination of the modified resection line of reserved gallbladder were analyzed in the observation group. Results:There was no significant difference in age, male proportion, type of Mirizzi syndrome and conversion rate of laparotomy between the two groups (all P>0.05). In the observation group, the operative time was (208.7±32.0) min, the intraoperative blood loss was (50.5±23.8) ml, and the biliary leakage was 7.1% (3/42), which was lower than that in the control group (228.2±33.9) min, (73.8±31.0) ml, 26.3% (10/38). The differences were statistically significant (all P<0.05). Of 37 cases (88%) showed common hepatic duct and common bile duct successfully in the observation group. In the observation group, ICG fluorescence imaging was used to determine the gallbladder resection line in 8 cases (19.0%). The gallbladder flap without fluorescence imaging was removed. Conclusion:ICG fluorescence imaging in LC for Mirizzi syndrome patients can identify the common bile duct and hepatic duct to guide surgical resection, determine the gallbladder flap resection line, reduce postoperative bile leakage and bleeding, and accelerate the surgical progress.

Purpose: To evaluated the efficacy and safety of gelatinized Maca (Lepidium meyenii) for eugonadal patients with late onset hypogonadism symptoms (LOH). Materials and Methods: Participants were instructed to receive 1,000 mg of Maca or placebo, two pills at a time, three times per day for 12 weeks before food intake. To evaluate the efficacy of the drug, Aging Males’ Symptoms scale (AMS), Androgen Deficiency in the Aging Males (ADAM), International Prostate Symptom Score (IPSS), and International Index of Erectile Function (IIEF) questionnaires, serologic tests (total testosterone and free testosterone, total cholesterol, high density lipoprotein cholesterol, low density lipoprotein cholesterol, triglyceride), body weight, and waist circumference were assessed at 4 and 12 weeks after treatment. Results: A total of 80 participants were enrolled and randomly assigned to Maca treated group (n=41) or the placebo group (n=39). AMS, IIEF, and IPSS were significantly (p<0.05) improved in Maca treated group than in the placebo group. ADAM positive rate was also significantly (p<0.0001) decreased in Maca treated group. Conclusions Maca may be considered an effective and safe treatment for eugonadal patients with late onset hypogonadism symptoms.

Metastasis is the main cause of poor prognosis of malignant tumors， and intervention with metastasis is the key measure in the treatment of malignant tumors. Hematogenous metastasis， the most common tumor metastasis， falls into the category of "Chuanshe" in traditional Chinese medicine （TCM）， with Qi deficiency and blood stasis as the critical pathogenesis. In the fight against malignant tumors， TCM emphasizes the reinforcement of healthy Qi and the elimination of pathogenic factors， exhibiting its action advantages of multiple targets， multiple mechanisms， and multiple levels. Extensive clinical evidence has shown the exact efficacy of Chinese herbal compounds designed for invigorating Qi and activating blood in delaying the progression of tumor disease and prolonging the survival period of patients. In view of the important role of hematogenous metastasis in the prognosis of tumors， more and more studies have explored the effects and mechanisms of Chinese herbal compounds capable of invigorating Qi and activating blood in intervening in hematogenous metastasis. This paper summarized the relevant literature reports in China and abroad on the intervention of Chinese herbal compounds capable of invigorating Qi and activating blood in the hematogenous metastasis of malignant tumors， in order to provide a theoretical basis for the clinical application of Qi-invigorating and blood-activating therapy in the treatment of malignant tumors. It has been found that Chinese herbal compounds formulated for invigorating qi and activating blood are effective in hindering several key steps in hematogenous metastasis through various mechanisms， including regulating the expression of cell adhesion molecules， inhibiting extracellular matrix degradation and angiogenesis， enhancing the killing effect of immunity， and improving blood hypercoagulability and hyperviscosity. Furthermore， the combination of invigorating Qi and activating blood targets the pathogenesis essence （Qi deficiency and blood stasis， characterized by sthenia in origin and asthenia in superficiality） of malignant tumor much better. Some comparative studies have demonstrated that the anti-metastasis effect of Qi-invigorating and blood-activating therapy is significantly stronger than that of the Qi-invigorating or blood-activating therapy alone， and such combination avoids the possible risk of the metastasis of malignant tumors triggered by the use of either of them. This study has provided some reference for the current clinical application of TCM for improving the prognosis of malignant tumors.
