Objective To explore the impact of integrated traditional Chinese and Western medicine on the overall survival(OS)of patients with biliary tract carcinoma(BTC),and to analyze the related factors affecting the OS of patients with BTC,so as to provide accurate prognosis assessment for clinical diagnosis and treatment.Methods The medical records of 198 patients with BTC in Henan Provincial Hospital of Traditional Chinese Medicine from February 2018 to October 2023 were retrospectively analyzed.The Cox proportional hazards model was utilized to analyze the independent prognostic factors affecting the OS of BTC patients.Survival curves were constructed using the Kaplan-Meier method,and the Log-rank test was employed to compare median OS differences among various groups.Results A total of 116 patients with BTC were included.There were 59 cases(50.86％)in the Western medicine group,with a median OS of(14±2.77)months,and the 1-,2-and 3-year OS rates were 81.36％,61.02％and 46.11％,respectively.There were 57 cases(49.14％)in the integrated traditional Chinese and Western medicine group,with a median OS of(29±3.91)months,and the 1-,2-and 3-year OS rates were 82.32％,67.64％and 58.00％,respectively.There was a statistically significant difference in survival time between the two groups(P=0.038).Univariate analysis indicated that age,clinical stage,surgical treatment,chemotherapy,targeted therapy,local therapy and integrated traditional Chinese and Western medicine were significantly correlated with OS in BTC patients(all P＜0.05).Multivariate analysis revealed that age,clinical stage,surgical treatment,chemotherapy,targeted therapy,local therapy,and integrated traditional Chinese and Western medicine had significant effects on the OS of patients with BTC(all P＜0.05).Conclusion The median OS of the traditional Chinese and Western medicine groups was significantly longer than that of the Western medicine group,and the long-term OS rate of the patients was significantly better than that of the Western medicine group.Age,clinical stage,surgery,chemotherapy,targeted therapy,local therapy,and integrated traditional Chinese and Western medicine are independent prognostic factors affecting OS in patients with BTC.

Obesity usually exacerbates the immunosuppressive tumor microenvironment (ITME), hindering CD8⁺ T cell infiltration and function, which further represents a significant barrier to the efficacy of immunotherapy. Herein, a multifunctional liposomal system (CR-Lip) for encapsulating celastrol (CEL) was utilized to remodel obesity-related ITME and improve cancer immunotherapy, wherein Ginsenoside Rg3 (Rg3) was detected interspersed in the phospholipid bilayer and its glycosyl exposed on the surface of the liposome. CR-Lip had a relatively uniform size (116.5 nm), facilitating favorable tumor tissue accumulation through the interaction between Rg3 and glucose transporter 1 overexpressed in obese tumor cells. Upon reaching the tumor region, CR-Lip was found to induce the immunogenic cell death (ICD) of HFD tumor cells. Notably, the level of PHD3 in HFD tumor cells was effectively boosted by CR-Lip to effectively block metabolic reprogramming and increase the availability of major free fatty acids fuel sources. In vivo, experiments studies revealed that the easy-obtained nano platform stimulated enhanced the production of various cytokines in tumor tissues, DC maturation, CD8⁺ T-cell infiltration, and synergistic anticancer therapeutic potency with aPD-1 (tumor inhibition rate = 82.1%) towards obesity-related melanoma. Consequently, this study presented an efficacious approach to tumor immunotherapy in obese mice by encompassing tumor eradication, inducing ICD, and reprogramming metabolism. Furthermore, it offered a unique insight into a valuable attempt at the immunotherapy of obesity-associated related tumors.

Objective To determine the effect of the combined use of urokinase and glycoprotein Ⅱb/Ⅲa-targeted microbubbles prepared by direct conjugation method to dissolve the thromb in vivo and analyse the velocity tracing change of blood flow and explore the possible mechanism. Methods A total of 42 rabbits with platelet-rich thrombi in the femoral artery were randomized into 7 treatment groups ( n = 6 in each group): 1) ultrasound alone (US); 2) ultrasound plus non-targeted microbubbles ( US + M); 3) urokinase alone (UK) ;4) ultrasound, non-targeted microbubble and urokinase (US + M + UK); 5) ultrasound plus platelet-targeted microbubble ( US + R); 6) platelet-targeted microbubble plus urokinase (R + UK); 7)ultrasound, platelet-targeted microbubble and urokinase (US + R + UK). A total of 6 ml of infusion liquor of Urokinase,RGDS and microbubbles (SonoVue) were mixed by 1 ∶ 1 ∶ 1 ratio by the direct conjugation method, infusion via vein within 20 min. Ultrasound was conducted to lyse the clot for 30 min. The recanalization and the velocity tracing change of blood flow in thrombolytic process were evaluated at 120 min post treatment. Results For US, UK, US + M, US + R and US + M + UK groups, recanalization was failed. The R + UK and US + R + UK was recanalizated ( P ＜0.001 ). The blood flow velocity tracing was small and low width in US,UK, US + M, US + R and US + M + UK groups. The wave was high width and disorderly under the thrombolysis therapy in the R + UK and US + R + UK. The thrombolytic effect was demonstrated by the high-width and disorderly resonance changes in the blood flow spectrum during the thrombolytic therapy of US + R + UK. Conclusions The blood flow spectrum of groups had different characteristics in vivo when thrombus was issolved,ultrasonic resonance might be the possible mechanism.

Objective To investigate the value of ultrasonography in evaluating the femoral artery thrombosis in rabbit. Methods Thrombosis was induced by external application with 10% ferric chloride and transient femoral artery-occlusion with bulldog clamp in twenty New-Zealand rabbits. The thrombosis was monitored by both Doppler flowmeter and ultrasonography. The histopathological result was used as the golden standard. The consistency of the above two results with the golden standard was analyzed. Results Thirty-two femoral arteries thrombosis were produced successfully. There was high consistency between the results of ultrasonic evaluation and histopathological examination (Kappa = 0. 720, P ＜ 0. 001 ), and moderate consistency between the results of Doppler flowmeter evaluation and histopathological examination (Kappa = 0. 546, P ＜0. 001 ). Within the thirty-two femoral arteries thrombosis, there were nineteen arteries with occlusive thrombus examined by histopathological means. Both the results of Doppler flowmeter and ultrasonography were highly consistent with the results of histopathological examination (Kappa = 0. 800 and 0.798 respectively, P ＜ 0. 001 ). Conclusions There is high consistency between the results of ultrasonic evaluation and histopathological examination for the common femoral artery thrombosis in rabbit.In the non-occlusive thrombus diagnosing,ultrasonography is better than Doppler flowmeter.
