This paper summarizes Professor WANG Yaoxian's experience in treating diabetic kidney disease （DKD） from the perspective of spleen and stomach based on the "internal heat leading to concretions" theory. It is considered that internal heat leading to concretions constitutes the core pathogenesis of DKD， with the spleen and stomach serving as the source of internal heat； therefore， treatment should be based on regulating the spleen and stomach. In the early stage of DKD， dysfunction of the spleen and stomach leads to the initial generation of internal heat. Common syndrome patterns include gastrointestinal heat accumulation and constrained heat in the liver and stomach， for which modified Gegen Qinlian Decoction （葛根芩连汤） can be used to clear heat bind while modified Dachaihu Decoction （大柴胡汤） is used to clear stomach and soothe liver， respectively. In the middle stage of DKD， weakness of the spleen and stomach results in the initial formation of concretions and conglomerations. Common patterns include spleen deficiency with prevalence of dampness and deficiency of both the spleen and kidney. Treatment emphasizes strengthening the spleen and resolving dampness， raising yang and boosting the stomach with modified Shengyang Yiwei Decoction （升阳益胃汤）， or supplementing spleen and boosting kidney， dissipating bind and dispe-ring concretions with modified Shenqi Dihuang Decoction （参芪地黄汤）， respectively. In the late stage of DKD， it is characterized by spleen and stomach depletion， and rampant accumulation of turbidity and toxin， and the common syndrome patterns are damp-turbidity obstruction in the middle jiao （焦） and spleen-kidney yang deficiency. Treatment aims to remove turbidity and harmonize the stomach， or to warm the kidney and strengthen the spleen while elimina-ting turbidity， using modified Dahuang Gancao Decoction（大黄甘草汤） and Jupi Zhuru Decoction （橘皮竹茹汤） or modified Baoyuan Decoction （保元汤） and Lizhong Decoction （理中汤）， respectively. In clinical practice， appropriate formulas and medications are flexibly selected according to specific syndromes.

ObjectiveTo observe the clinical efficacy and safety of Yuyin Lidan granules （YYLD） in preventing the recurrence of common bile duct stones （CBDS） in patients with liver and gallbladder dampness-heat syndrome following endoscopic retrograde cholangiopancreatography （ERCP）. MethodsThis randomized， parallel， controlled trial enrolled postoperative CBDS-ERCP patients who met the inclusion and exclusion criteria. Sixty-four patients were randomly assigned to an observation group or a control group， with 32 cases in each. Both groups received conventional Western medical treatment after ERCP， while the observation group additionally received YYLD for 8 weeks. The follow-up period lasted for 1 year. The efficacy indicators included bile bilirubin levels， traditional Chinese medicine （TCM） syndrome scores， clinical efficacy rate， pancreatitis and inflammation markers， postoperative liver function， and CBDS recurrence rate at 1-year follow-up， which were used to jointly evaluate the clinical efficacy and safety of both groups. ResultsA total of 56 patients completed the study and were included in the final analysis， i.e.， 29 in the observation group and 27 in the control group. Baseline characteristics were comparable between the two groups. Compared with pre-treatment and with the control group after treatment， the bile bilirubin level in the observation group significantly decreased （P<0.05）. After treatment， the clinical cure and marked improvement rates were higher in the observation group than in the control group， showing a statistically significant difference in overall clinical efficacy （P<0.05）. Compared with pre-treatment， the primary and secondary symptoms in the observation group， as well as the primary symptom and the secondary symptom of nausea and vomiting in the control group （weeks 4 and 8）， were significantly reduced （P<0.05）. Compared with the control group after treatment， the observation group showed significant reductions in the primary symptom of loose stools/constipation （day 5 and week 4） and in three secondary symptoms， i.e.， bitter taste and sticky dry mouth， abdominal distension and poor appetite （throughout the treatment period）， and general heaviness and fatigue （day 5 and week 4）， with statistical differences （P<0.05）. Compared with pre-treatment， both groups showed decreased lipase and urinary amylase levels （P<0.05）. However， no significant between-group differences were observed in pancreatitis or inflammation-related indices after treatment. Compared with pre-treatment， all liver function indicators in the observation group and alanine aminotransferase （ ALT ）， γ-glutamyl transferase （ γ-GT ）， alkaline phosphatase （ALP）， and conjugated bilirubin in the control group significantly decreased at weeks 4 and 8 （P<0.05）. Compared with the control group after treatment， only serum total bilirubin and unconjugated bilirubin were significantly reduced in the observation group during the treatment period （P<0.05）. ConclusionYYLD combined with conventional Western medical treatment can effectively regulate bilirubin metabolism （in bile and serum）， improve TCM clinical symptoms， and prevent CBDS recurrence after ERCP in patients with liver and gallbladder dampness-heat syndrome. This regimen is safe and effective and is worthy of further clinical research and promotion.

Objective: To define the mechanism by which swine TRIM25 restricts vesicular stomatitis virus replication. Methods: Porcine 3D4/21 cells with TRIM25 overexpression or knockdown were infected with vesicular stomatitis virus. Viral replication was quantified by immunoblotting, quantitative reverse transcription polymerase chain reaction, and 50% tissue culture infectious dose assays. Type I interferon signaling was assessed by transcript quantification, interferon-beta and interferon-stimulated response element reporter assays, and co-immunoprecipitation.Viral RNA binding was tested by RNA immunoprecipitation. Results: TRIM25 overexpression reduced viral RNA and infectious titers, whereas TRIM25 knockdown increased replication (p < 0.01). TRIM25 increased interferon-beta and interferon-stimulated gene expression and enhanced interferon-beta and interferonstimulated response element promoter activity (p < 0.01). Mechanistically, TRIM25 promoted Lys63-linked ubiquitination of RIG-I and increased phosphorylation of TANK-binding kinase 1 and interferon regulatory factor 3. TRIM25 also bound vesicular stomatitis virus genomic RNA, and binding required the C-terminal region. Conclusions and Relevance: Porcine TRIM25 restricts vesicular stomatitis virus replication by amplifying type I interferon signaling and directly binding viral RNA.

Objective:To investigate the imaging characteristics of small intestinal epithe-lioid angiosarcoma.Methods:The retrospective and descriptive study was conducted. The clinical data of 5 male patients with small intestinal epithelioid angiosarcoma who were admitted to 3 medical centers, including Yantaishan Hospital of Yantai et al, from January 2013 to December 2023 were collected. The age of 5 patients was 54 (range, 36-73)years. All 5 patients underwent computer tomography (CT) plain scan and dynamic contrast-enhanced scan, with 1 patient also undergoing magnetic resonance imaging (MRI) plain scan. Observation indicators: (1) results of CT and MRI examination; (2) surgical conditions and postoperative pathological examination; (3) follow-up. Measurement data with skewed distribution were represented as M(range), and count data were described as absolute numbers. Results:(1) Results of CT and MRI examination. Of the 5 patients with small intestinal epithelioid angiosarcoma, two cases were primary small intestinal epithelioid angiosarcoma and the other three cases were metastatic small intestinal epithelioid angiosarcoma. None of the five patients exhibited metastasis to other solid organs, and no significant ascites or peritoneal metastases. ① In two cases of primary small intestinal epithelioid angiosarcoma, three tumors were identified, appearing as round soft tissue nodules on CT plain scan, primarily growing intraluminally. The CT value for tumors of those two cases on plain scan were 30, 35, 32 HU, respec-tively. During the arterial phase of enhanced CT scan, moderate enhancement was observed for tumors of those two cases, with CT value of 57, 72, 65 HU, respectively. During the venous phase of enhanced CT scan, significant enhancement was observed for tumors of those two cases, with CT value of 76, 86, 88 HU, respectively. During the delayed phase of enhanced CT scan, slightly decreased enhancement was observed for tumors of those two cases, with CT value of 74, 79, 72 HU, showing no significant necrosis or cystic changes within the tumors. ② In three cases of metastatic small intestinal epithelioid angiosarcoma, four tumors were identified with uneven thickening of the intestinal wall appeared on CT plain scan. The CT value for tumors of those three cases on plain scan were 39, 37, 38, 28 HU, respectively. During the arterial phase of enhanced CT scan, mild to moderate enhancement was observed for tumors of those three cases, with CT value of 57, 56, 52, 45 HU, respectively. During the venous phase of enhanced CT scan, significant enhancement was observed for tumors of those three cases, with CT value of 84, 88, 82, 77 HU, respectively. During the delayed phase of enhanced CT scan, further changes of increased or decreased enhancement was observed for tumors of those three cases, with CT value of 95, 78, 72, 70 HU. One case of those three patients had thickened intestinal wall with low signal on T1-weighted imaging, heterogeneous high signal on fat-suppressed T2-weighted imaging, significant high signal on diffusion-weighted imaging and low signal on apparent diffusion coefficient imaging on MRI scan. (2) Surgical conditions and post-operative pathological examination. All five cases underwent complete tumor resection. In two cases of primary epithelioid angiosarcoma with three small intestinal tumor foci, there were two tumors invading the serosa and one tumor invading the submucosa. All three metastatic epithelioid angio-sarcoma cases showed four tumors invasion through the serosa, with one case exhibiting mesenteric lymph node metastasis. Microscopic examination revealed hemorrhagic necrosis on the tumor mucosal surface, with tumor cells located in the submucosa or throughout the intestinal wall, displaying infiltrative growth patterns. The distribution was diffuse, with local networks forming irregularly sized vascular-like structures, containing red blood cells and forming blood sinuses and vascular networks. Tumor cells were arranged in solid sheets, strands, and nests, exhibiting spindle-shaped or epithelioid characteristics, with marked atypia, large nuclei, prominent nucleoli, and mitotic figures. Immunohistochemical analysis showed diffuse strong positivity for CD31, Fli-1, and Vim in all five patients. (3) Follow-up. All five patients were followed up postoperatively for 6(range, 3?48)months. During the follow-up period, four patients succumbed to widespread metastasis. One patient with metastatic small intestinal epithelioid angiosarcoma underwent six cycles of chemotherapy and remained in good condition four years post-surgery.Conclusion:The imaging characteristics of small intestinal epithelioid angiosarcoma include abnormal thickening or masses of the intestinal wall.

Persistent atrial fibrillation and other factors can cause mitral and tricuspid annular dilation and leaflet regurgitation,leading to severe functional mitral and tricuspid regurgitation.Patients often experience significant heart failure symptoms and poor prognosis.For patients with severe mitral or tricuspid regurgitation who are at high risk or contraindicated for surgical procedures,transbronchial repair(TEER)is an important alternative therapy that can effectively reduce valve regurgitation and improve cardiac function;Although there is a lack of large-scale data on atrial functional reflux,existing experience still shows that TEER can significantly reduce reflux and improve patients'quality of life.However,double valve intervention therapy poses challenges,especially when combined with TEER repair,which is technically more complex,time-consuming,and carries higher risks.Foreign data shows that simultaneous or staged double valve intervention can safely improve cardiac function and increase survival rates,but the optimal intervention strategy still needs further research.Due to the fact that tricuspid TEER devices have not yet been launched in China,only staged treatment can be adopted at present.This case report shows a patient with severe atrial functional mitral and tricuspid regurgitation who underwent staged transcatheter edge to edge repair surgery successfully.During a 1-year follow-up,bilateral valve regurgitation continued to improve,indicating that staged repair of bilateral atrioventricular valve regurgitation through the catheter margin is a feasible and effective treatment option.
