To solve ab...The existing interventional therapy robots for the microwave ablation of liver tumors have a poor clinical applicability with a large volume, low positioning speed and complex automatic navigation control. To solve above problems, a composite configuration interventional therapy robot with passive and active joints is developed. The design of composite configuration reduces the size of the robot under the premise of a wide range of movement, and the robot with composite configuration can realizes rapid positioning with operation safety. The cumulative error of positioning is eliminated and the control complexity is reduced by decoupling active parts. The navigation algorithms for the robot are proposed based on solution of the inverse kinematics and geometric analysis. A simulation clinical test method is designed for the robot, and the functions of the robot and the navigation algorithms are verified by the test method. The mean error of navigation is 1.488 mm and the maximum error is 2.056 mm, and the positioning time for the ablation needle is in 10s. The experimental results show that the designed robot can meet the clinical requirements for the microwave ablation of liver tumors. The composite configuration is proposed in development of the interventional therapy robot for the microwave ablation of liver tumors,which provides a new idea for the structural design of medical robots.展开更多

It is well-known that Professor Lin Gui is the founding father of Interventional radiology. Under the leadership of Lin Gui and other professors, interventional therapy of liver cancer has swiftly progressed in China. Indeed, TAI, TAE, TACE and ablation therapy have witnessed great innovations in hardware facil ities, technical means, and therapeutic philosophy, while incorporating Chinese characteristics. As with the development of combined interventional therapy in China, interventional treatment of liver cancer has gradually started the process of precision and individualization. Actually, multidisciplinary, multimodal, and polymorphic treatments will be the most suitable pattern for liver cancer in the future, among which combination of interventional therapy with targeted, immunological treatments and information technology(IT) tools may bring a revolutionary breakthrough in liver cancer treatment.展开更多

Methods: A total of 40 HCC patients with hepatocirrhosis and hypersplenism, hospitalized during January 2013 to June 2014, were enrolled and randomized into control group and observation group. Both groups received partial splenic embolization combined with transcatheter arterial chemoembolization. Besides, observation group orally took lactulose 30 m L/d. Four days before interventional therapies and at day 1, 3, 7 and 14 after therapies, fasting venous blood was collected to detect white blood cell count, red blood cell count(RBC), and platelet count(PLT). Four days before therapies and at day 7 and 14 after therapies, the levels of alanine aminotransferase, aspartate transaminase, total bilirubin, malondialdehyde, super-oxide dismutase(SOD), IFN-α, and IL-4 as well as the distribution of T cell subsets in peripheral blood were tested. Complications were observed after interventional therapies. Results: Before interventional therapies the levels of white blood cell count, PLT and RBC in both groups showed no difference, while after interventional therapies the levels of PLT and RBC in both groups showed an increasing tendency(P<0.05). At day 14 after interventional therapies, the level of blood cell as well as that of SOD, IFN-α and IL-4 in serum were significantly higher than that before therapies; meanwhile, the levels of alanine aminotransferase and total bilirubin of observation group after therapies were significantly lower than before and control group(P<0.05), the levels of CD4+/CD8+, SOD and IFN-α were all higher than before and control group(P<0.05). Conclusions: Oral administration of lactulose could adjust the imbalance of oxidation system/antioxidant system in HCC patients with hepatocirrhosis and hypersplenism after interventional therapies, and improve the antitumor immunity and prognosis.展开更多

Based on the changes in serum LDH levels before and after treatment, patients were classified into two groups: LDH increased group(22 cases) and LDH decreased group(30 cases). The relationship between LDH levels and efficacy of TACE treatment was analyzed in the four groups retrospectively. Results No significant difference was seen in the clinical characteristics(gender, median age, performance status Eastern Cooperative Oncology Group, and staging system) between the control and observation groups. The efficacy rate in the control group was 57.7%, whereas that in the observation group was 42.3%(P > 0.05). The 1-year survival rate in the observation group was 53.8% and that in the control group was 84.6%(P < 0.05).Conclusion Serum LDH levels may be of clinical value in evaluating the efficacy of TACE in patients with hepatocellular carcinoma.展开更多

However, effective treatments for patients with acute ischemic stroke are limited. Intravenous recombinant tissue plasminogen activator(iv rtPA) within 4.5 h after onset has been approved as a standard treatment for patients with acute ischemic stroke. However, due to time constraints, less than one percent of acute ischemic stroke patients in Thailand are able to obtain iv rtPA. Although endovascular interventional therapy has not yet been approved as standard treatment in acute ischemic stroke, it is the one of the potentially effective treatment options. There are several reliable methods of endovascular therapy for acute ischemic stroke patients. Endovascular interventional therapy has rarely been done in Thailand. We report seven patients with successful recanalization after endovascular treatment in acute large vessel stroke from a single stroke center in Thailand. Patient screening and selection with multimodal imaging protocol and multimodality methods of endovascular interventional therapy are described.展开更多

METHODS Double-phase enhancementscanning spiral CT and DSA were performed in 56 pathologically confi rmed lung cancer cases, in order to evaluate angiogenesis of the tumors. The patients included 36 males and 20 females, with ages ranging from 33 to 76 years (average of 53). Assessments and indexes for SCT and DSA examinations were as follows: a) Peak value (PV) of the cancerous focus was the difference between the maximum CT value after enhancement and the CT value of a plain scan; b) The abnormally distorted and expanded new vessels of the cancerous focus which could be macroscopically discriminated; c) DSA staining of the focus of cancer was sparse, grid-like and dense. Chemotherapy and embolotherapy via the bronchial artery (interventional therapy) were conducted. Radiotherapy was added for some of the solid tumors with a diameter exceeding 4 cm. RESULTS a) There were 25 cases with a central-type lesion, among which 4 were small cell lung cancers (SCLC) and 21 non-small cell lung cancers (NSCLC). The cases with a peripheral location accounted for 31 of the total, with a maximum diameter of 1.5 to 13.5 cm and a median of 4.2 cm, including 5 small cell lung cancers and 26 NSCLC cases. b) The reinforced PVs of the cancerous foci were as follows: The PV ranged from 45 to 70 Hu in 34 cases, 25 to 45 Hu in 19, and 10 to 25 Hu in 3. Sparse DSA staining occurred in 3 cases, there was uneven grid-like staining in 22 and dense staining in 31; c) The interventional therapy via the bronchial artery was con-ducted twice in 5 cases with the SCLC, and three times in 4 SCLC cases. For 3 of the latter cases, a dose of 5,000 to 7,000 cGy radiation therapy was added during the interventional treatment. Complete remissions (CR) were seen in 88.9% of the cases (8/9) and partial remission (PR) in 11.1% (1/9). Interventional therapy was conducted twice in 8 cases with NSCLC and three times in 30 with NSCLC and four times in 9 cases. Among the total cases, 13 received radiotherapy during interventional therapy, with a radiation dose of 5,000-7,000 cGy; The CR rate was 78.7% (37/47), PR was 14.9% (7/47) and the rate of non-remission was 6.4% (3/47). CONCLUSION Using imaging technology, analysis of angiogenesis of lung cancers was employed to accurately detect and quantify angiogenesis. This analysis was combined for interventional therapy, using embolizing agents and large doses of the anti-tumor drugs and angiogenesis inhibitors. The agents were selectively delivered into the tumor vessels to eliminate the primary tumor, in order to depress distant metastases and thus enhance the curative effect of the therapy.展开更多

ME...AIM: To analyze the clinical manifestations and the effectiveness of therapy in patients with orthotopic liver transplantation (OLT)-associated hepatic artery stenosis (HAS) and non-anastomosis bile duct stricture. METHODS: Nine cases were diagnosed as HAS and non-anastomosis bile duct stricture. Percutaneous transluminal angioplasty (PTA) was performed in four HAS cases, and expectant treatment in other fi ve HAS cases; percutaneous transhepatic bile drainage, balloon dilation, stent placement were performed in all nine cases. RESULTS: Diffuse intra-and extra-bile duct stricture was observed in nine cases, which was associated with bile mud siltation and biliary infection. Obstruction of the bile duct was improved obviously or removed. Life span/ follow-up period was 13-30 mo after PTA of four HAS cases, 6-23 mo without PTA of other fi ve cases. CONCLUSION: Progressive, non-anastomosis, and diffuse bile duct stricture are the characteristic manifestations of HAS and non-anastomosis bile duct stricture after OLT. These are often associated with bile mud siltation, biliary infection, and ultimate liver failure. Interventional therapy is signifi cantly benefi cial.展开更多

文摘Objective: To investigate the influence of lactulose on immunity of hepatocellular carcinoma(HCC) patients with hepatocirrhosis and hypersplenism after double-interventional therapies. Methods: A total of 40 HCC patients with hepatocirrhosis and hypersplenism, hospitalized during January 2013 to June 2014, were enrolled and randomized into control group and observation group. Both groups received partial splenic embolization combined with transcatheter arterial chemoembolization. Besides, observation group orally took lactulose 30 m L/d. Four days before interventional therapies and at day 1, 3, 7 and 14 after therapies, fasting venous blood was collected to detect white blood cell count, red blood cell count(RBC), and platelet count(PLT). Four days before therapies and at day 7 and 14 after therapies, the levels of alanine aminotransferase, aspartate transaminase, total bilirubin, malondialdehyde, super-oxide dismutase(SOD), IFN-α, and IL-4 as well as the distribution of T cell subsets in peripheral blood were tested. Complications were observed after interventional therapies. Results: Before interventional therapies the levels of white blood cell count, PLT and RBC in both groups showed no difference, while after interventional therapies the levels of PLT and RBC in both groups showed an increasing tendency(P<0.05). At day 14 after interventional therapies, the level of blood cell as well as that of SOD, IFN-α and IL-4 in serum were significantly higher than that before therapies; meanwhile, the levels of alanine aminotransferase and total bilirubin of observation group after therapies were significantly lower than before and control group(P<0.05), the levels of CD4+/CD8+, SOD and IFN-α were all higher than before and control group(P<0.05). Conclusions: Oral administration of lactulose could adjust the imbalance of oxidation system/antioxidant system in HCC patients with hepatocirrhosis and hypersplenism after interventional therapies, and improve the antitumor immunity and prognosis.
文摘Objective The aim of the study was to investigate the role of serum lactate dehydrogenase(LDH) levels in evaluating the efficacy of transcatheter arterial chemoembolization(TACE) for primary liver cancer.Methods A total of 52 patients with liver cancer admitted in our hospital(Huangzhou District People's Hospital, Huanggang, China) from June 2015 to December 2017 were selected and divided into control group(LDH of ≤ 450 U/L, n = 26) and observation group(LDH of > 450 U/L, n = 26), based on the pretreatment level of LDH. Based on the changes in serum LDH levels before and after treatment, patients were classified into two groups: LDH increased group(22 cases) and LDH decreased group(30 cases). The relationship between LDH levels and efficacy of TACE treatment was analyzed in the four groups retrospectively. Results No significant difference was seen in the clinical characteristics(gender, median age, performance status Eastern Cooperative Oncology Group, and staging system) between the control and observation groups. The efficacy rate in the control group was 57.7%, whereas that in the observation group was 42.3%(P > 0.05). The 1-year survival rate in the observation group was 53.8% and that in the control group was 84.6%(P < 0.05).Conclusion Serum LDH levels may be of clinical value in evaluating the efficacy of TACE in patients with hepatocellular carcinoma.

文摘Stroke is an important cause of death and disability in adults. However, effective treatments for patients with acute ischemic stroke are limited. Intravenous recombinant tissue plasminogen activator(iv rtPA) within 4.5 h after onset has been approved as a standard treatment for patients with acute ischemic stroke. However, due to time constraints, less than one percent of acute ischemic stroke patients in Thailand are able to obtain iv rtPA. Although endovascular interventional therapy has not yet been approved as standard treatment in acute ischemic stroke, it is the one of the potentially effective treatment options. There are several reliable methods of endovascular therapy for acute ischemic stroke patients. Endovascular interventional therapy has rarely been done in Thailand. We report seven patients with successful recanalization after endovascular treatment in acute large vessel stroke from a single stroke center in Thailand. Patient screening and selection with multimodal imaging protocol and multimodality methods of endovascular interventional therapy are described.
文摘OBJECTIVE To investigate the significance of angiogenesis of lung cancer, in order to provide a scientific basis for interventional therapy. METHODS Double-phase enhancementscanning spiral CT and DSA were performed in 56 pathologically confi rmed lung cancer cases, in order to evaluate angiogenesis of the tumors. The patients included 36 males and 20 females, with ages ranging from 33 to 76 years (average of 53). Assessments and indexes for SCT and DSA examinations were as follows: a) Peak value (PV) of the cancerous focus was the difference between the maximum CT value after enhancement and the CT value of a plain scan; b) The abnormally distorted and expanded new vessels of the cancerous focus which could be macroscopically discriminated; c) DSA staining of the focus of cancer was sparse, grid-like and dense. Chemotherapy and embolotherapy via the bronchial artery (interventional therapy) were conducted. Radiotherapy was added for some of the solid tumors with a diameter exceeding 4 cm. RESULTS a) There were 25 cases with a central-type lesion, among which 4 were small cell lung cancers (SCLC) and 21 non-small cell lung cancers (NSCLC). The cases with a peripheral location accounted for 31 of the total, with a maximum diameter of 1.5 to 13.5 cm and a median of 4.2 cm, including 5 small cell lung cancers and 26 NSCLC cases. b) The reinforced PVs of the cancerous foci were as follows: The PV ranged from 45 to 70 Hu in 34 cases, 25 to 45 Hu in 19, and 10 to 25 Hu in 3. Sparse DSA staining occurred in 3 cases, there was uneven grid-like staining in 22 and dense staining in 31; c) The interventional therapy via the bronchial artery was con-ducted twice in 5 cases with the SCLC, and three times in 4 SCLC cases. For 3 of the latter cases, a dose of 5,000 to 7,000 cGy radiation therapy was added during the interventional treatment. Complete remissions (CR) were seen in 88.9% of the cases (8/9) and partial remission (PR) in 11.1% (1/9). Interventional therapy was conducted twice in 8 cases with NSCLC and three times in 30 with NSCLC and four times in 9 cases. Among the total cases, 13 received radiotherapy during interventional therapy, with a radiation dose of 5,000-7,000 cGy; The CR rate was 78.7% (37/47), PR was 14.9% (7/47) and the rate of non-remission was 6.4% (3/47). CONCLUSION Using imaging technology, analysis of angiogenesis of lung cancers was employed to accurately detect and quantify angiogenesis. This analysis was combined for interventional therapy, using embolizing agents and large doses of the anti-tumor drugs and angiogenesis inhibitors. The agents were selectively delivered into the tumor vessels to eliminate the primary tumor, in order to depress distant metastases and thus enhance the curative effect of the therapy.

文摘AIM: To analyze the clinical manifestations and the effectiveness of therapy in patients with orthotopic liver transplantation (OLT)-associated hepatic artery stenosis (HAS) and non-anastomosis bile duct stricture. METHODS: Nine cases were diagnosed as HAS and non-anastomosis bile duct stricture. Percutaneous transluminal angioplasty (PTA) was performed in four HAS cases, and expectant treatment in other fi ve HAS cases; percutaneous transhepatic bile drainage, balloon dilation, stent placement were performed in all nine cases. RESULTS: Diffuse intra-and extra-bile duct stricture was observed in nine cases, which was associated with bile mud siltation and biliary infection. Obstruction of the bile duct was improved obviously or removed. Life span/ follow-up period was 13-30 mo after PTA of four HAS cases, 6-23 mo without PTA of other fi ve cases. CONCLUSION: Progressive, non-anastomosis, and diffuse bile duct stricture are the characteristic manifestations of HAS and non-anastomosis bile duct stricture after OLT. These are often associated with bile mud siltation, biliary infection, and ultimate liver failure. Interventional therapy is signifi cantly benefi cial.
