ObjectiveTo explore the application value of multidisciplinary collaborative team (MDT) model in retroperitoneal tumors involving large vessels.MethodsThree cases of retroperitoneal tumors involving great vessels admitted to Xiang’an Hospital of Xiamen University in 2019 were retrospectively analyzed. With the support of 3D visual reconstruction and virtual reality (VR) technology, we performed MDT discussion and three cases received treatment of surgery, intervention, and targeted therapy.ResultsCase 1 was discussed by MDT and concluded that, based on CT examination, 3D reconstruction, and VR virtual image results, the tumor on the right side was determined to be completely resectable. The left tumor was judged to be unresectable, and the proposed treatment plan was right metastatic tumor resection + left metastatic tumor radiofrequency ablation. After surgery case 1 had been followed up for 6 months. The symptoms of diarrhea were significantly improved. CT reexamination showed that liver lesions and left retroperitoneal lesions were the same size and the condition was stable. After discussion by MDT, radiofrequency ablation around the tumor was proposed for case 2. This case was followed up for 3 months after surgery, and CT reexamination showed no new lesion in retroperitoneum. After MDT discussion, we concluded that arteriovenous fistula of case 3 had no indications for surgery, and proposed interventional combined with targeted therapy. After treatment, the tumor was found to be smaller after reexamination in 8 months than before treatment, and the efficacy was evaluated as partial remission. The follow-up was continued.ConclusionThe future development trend of retroperitoneal tumor therapy involving great vessels is to evaluate each patient’s condition under the MDT mode by using 3D visual reconstruction and VR technology, and to formulate the individualized treatment plan of operation combined with other treatments.
【Abstract】Objective To investigate the anatomic structure and experimental methods of peribiliary vascular plexus(PVP) in rat’s hepatic portal bile duct.Methods To observe the morphological structure of PVP in rat’s hepatic portal bile duct after the hepatic artery was perfused with Chinese ink and transparency management, performed and to make three dimensional reconstruction of PVP’s spacial structure in MoticBuaa3Dvol software.Results The microvascular distribution and plane structure of PVP in rat’s hepatic portal bile duct could be shown clearly through Chinese ink perfusion and transparency management. The three dimensional structure of PVP could be reconstructed effectively by MoticBuaa3Dvol software, its effect was verisimilitude. Conclusion Chinese ink perfusion and vitrification is a simple and easy method in PVP’s morphologic study of rat’s hepatic portal bile duct. MoticBuaa3Dvol software is useful in microvascular study of hepatic portal bile duct.
【摘要】 目的 了解北京地区400例新型甲型H1N1流感患者的流行病学和临床特征，总结规律，进一步指导临床诊治。 方法 2009年5-12月期间，收治400例甲型H1N1流感确诊病例，主要采用描述性流行病学方法对患者资料进行回顾性分析，并运用单因素方差分析的方法对结果进行检验。 结果 患者以青年和儿童人群为主，47.0%的患者有明确甲型H1N1流感接触史，主要症状包括发热（98.8%）、咳嗽（85.8%）、咽痛（58.5%）。咽部充血（94.0%）和扁桃体肿大（49.5%）为主要体征。外周血白细胞正常或偏低，349例（82.3%）患者血清铁降低，268例（72.6%）患者C反应蛋白升高。在发病后不同时间内给予奥司他韦治疗的患者发热持续时间和咽拭子的阴转时间有显著差异（Plt;0.001）。 结论 新型甲型H1N1流感发病多以青年和儿童人群为主，以流感样症状为主，多数症状轻微，预后良好，C反应蛋白和血清铁的变化可能对于早期诊断有指导价值，奥司他韦早期抗病毒治疗可以缩短病程。【Abstract】 Objective To investigate the clinical and epidemiologic characteristics of pandemic influenza A (H1N1) virus infection in Beijing. Methods The epidemiological information and clinical characteristics of 400 patients with pandemic influenza A (H1N1) virus infection hospitalized in Beijing 302 Hospital from May to December, 2009 were analyzed retrospectively by descriptive epidemiology. One-way ANOVA was used to assess the results. Results H1N1 virus infection preferentially affected adolescents and young adults. The mean age of the patients was 23 years. A total of 189 (47.0%) of the patients had an identifiable epidemiologic link to another confirmed patient. The most common symptoms were fever (98.8%), cough (85.8%) and sore throat (58.5%). The main physical signs were pharyngeal portion congestion (94.0%) and antiadoncus (49.5%). The number of leukocytes in the peripheral blood was normal or low. The decreased serum iron and elevated C-reaction protein were found in 82.3% and 72.6% of the patients. There was significant difference in the duration of fever and viral shedding from throat swabs among the patients who accept the antiviral medication within the different time. Conclusion H1N1 virus infection preferentially affects adolescents and young adults, and presents with influenza-like illness. The clinical course of H1N1 virus infection is generally mild. The change of C-reaction protein and serum iron may be favorable for the diagnosis of H1N1. Early antiviral treatment may shorten the duration of fever and viral shedding.
