Effects of Ticagrelor on oxidative stress, coagulation function, platelet function and related factors in patients with coronary artery disease undergoing interventional therapy

Objective: To explore the effects of Ticagrelor on oxidative stress, coagulation function, platelet function and related factors in patients with coronary artery disease undergoing interventional therapy. Methods: A total of 140 patients with coronary artery disease who underwent percutaneous coronary intervention in our hospital from October 2016 to March 2018 were selected as the study subjects and were divided into control group (70 cases) and observation group (70 cases) by drawing lots. Both groups were treated with symptomatic routine therapy before operation. On this basis, the control group was treated with clopidogrel before operation, and the observation group was treated with Ticagrelor before operation on the basis of routine treatment. The changes of oxidative stress, coagulation index, platelet function and related factors were compared between the two groups before and after treatment. Results: Before treatment, there were no significant differences in oxidative stress factors, coagulation parameters, platelet parameters and related factors factors between the two groups. After treatment, the levels of MDA, MPAR, VEGF and MMP-9 in the two groups were lower than those before treatment, while the levels of SOD, APTT, TT and PT were higher than those before treatment;and the levels of MDA, MPAR, VEGF, MMP-9, APTT and PT in the observation group were significantly lower than those in the control group after treatment, while the levels fo SOD, TT and IPA in the observation group were significantly higher than those in the control group. Conclusions: Ticagrelor can better reduce oxidative stress injury, improve coagulation function and coronary stenosis, and inhibit platelet aggregation in patients with coronary heart disease undergoing PCI than clopidogrel. It has clinical popularization significance.

Landscape of transarterial chemoembolization represented interventional therapy for hepatocellular carcinoma

This article discusses the article written by Tan et al.Transarterial chemoembol-ization(TACE)is one of the main treatment methods for advanced hepatocellular carcinoma(HCC).There are other vascular interventional therapies,including drug-eluting bead TACE,transarterial radioembolization,and hepatic arterial infusion chemotherapy.TACE combined with anti-angiogenesis therapy may improve tumor control and prolong progression free survival.The combination therapy of TACE and immunotherapy may improve the clinical efficacy of HCC.In future research,more basic and clinical studies are needed to explore the immunogenic intervention therapy.

The history of interventional therapy for liver cancer in China

In China interventional therapy of liver cancer started in the 1980s. 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.

The Effect of Predictive Nursing Intervention on Cardiac Function and Clinical Outcomes in CCU Patients with Acute Myocardial Infarction After Interventional Therapy

Objective:To evaluate the impact of predictive nursing on the care of acute myocardial infarction(AMI)patients in the Coronary Care Unit(CCU)after interventional therapy.Methods:From September 2021 to September 2023,84 AMI patients admitted to the CCU were randomly divided into two groups:the experimental group(42 patients)received predictive nursing,and the reference group(42 patients)received conventional nursing.Cardiac function and clinical outcomes were compared between the groups.Results:Before nursing,there was no difference in cardiac function between the two groups(P>0.05).After nursing,the cardiac function of the experimental group was better than that of the reference group(P<0.05).The clinical outcomes of the experimental group were better than those of the reference group(P<0.05).Before nursing,there was no difference in psychological scores between the two groups(P>0.05).After nursing,the psychological scores of the experimental group were lower than those of the reference group(P<0.05).Conclusion:Predictive nursing can improve the cardiac function and clinical outcomes of AMI patients after interventional therapy and can also regulate patients’negative psychological states.

Successful recanalization with multimodality endovascular interventional therapy in acute ischemic stroke

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.

Influence of lactulose on interventional therapy for HCC patients with hepatocirrhosis and hypersplenism

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.

Role of serum lactate dehydrogenase levels in evaluating efficacy of interventional therapy for hepatocellular carcinoma

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.

Age-related driving mechanisms of retinal diseases and neuroprotection by transcription factor EB-targeted therapy

Retinal aging has been recognized as a significant risk factor for various retinal disorders,including diabetic retinopathy,age-related macular degeneration,and glaucoma,following a growing understanding of the molecular underpinnings of their development.This comprehensive review explores the mechanisms of retinal aging and investigates potential neuroprotective approaches,focusing on the activation of transcription factor EB.Recent meta-analyses have demonstrated promising outcomes of transcription factor EB-targeted strategies,such as exercise,calorie restriction,rapamycin,and metformin,in patients and animal models of these common retinal diseases.The review critically assesses the role of transcription factor EB in retinal biology during aging,its neuroprotective effects,and its therapeutic potential for retinal disorders.The impact of transcription factor EB on retinal aging is cell-specific,influencing metabolic reprogramming and energy homeostasis in retinal neurons through the regulation of mitochondrial quality control and nutrient-sensing pathways.In vascular endothelial cells,transcription factor EB controls important processes,including endothelial cell proliferation,endothelial tube formation,and nitric oxide levels,thereby influencing the inner blood-retinal barrier,angiogenesis,and retinal microvasculature.Additionally,transcription factor EB affects vascular smooth muscle cells,inhibiting vascular calcification and atherogenesis.In retinal pigment epithelial cells,transcription factor EB modulates functions such as autophagy,lysosomal dynamics,and clearance of the aging pigment lipofuscin,thereby promoting photoreceptor survival and regulating vascular endothelial growth factor A expression involved in neovascularization.These cell-specific functions of transcription factor EB significantly impact retinal aging mechanisms encompassing proteostasis,neuronal synapse plasticity,energy metabolism,microvasculature,and inflammation,ultimately offering protection against retinal aging and diseases.The review emphasizes transcription factor EB as a potential therapeutic target for retinal diseases.Therefore,it is imperative to obtain well-controlled direct experimental evidence to confirm the efficacy of transcription factor EB modulation in retinal diseases while minimizing its risk of adverse effects.

Objective: To explore the impact of interventional nursing on the therapeutic effect, negative emotions, and quality of life of patients undergoing cardiovascular and cerebrovascular interventional therapy. Methods: A total of 106 patients who underwent cardiovascular and cerebrovascular interventional treatment were collected and randomly divided into Group A (control) and Group B (observation), with 53 cases each. Group A received the routine nursing intervention and Group B received the interventional nursing intervention. The clinical efficacy, complications, negative emotions, quality of life, and nursing satisfaction of the two groups of patients were evaluated. Results: The total clinical effective rate of Group B (52/98.12%) was higher than that of Group A (45/84.91%) (χ^(2)= 4.371, P < 0.05). The total incidence of complications in Group B (2/3.78%) was lower than that of Group A (9/16.98%) (χ^(2)= 4.970, P < 0.05). The self-rating anxiety (SAS) score and self-rating depression (SDS) of Group B were lower than those of Group A (P < 0.001). The quality of life of Group B was significantly higher than that of Group A (P < 0.001). The nursing satisfaction of group B (51/96.22%) was higher than that of group A (43/81.13%) (χ^(2)= 6.014, P < 0.05). Conclusion: In the care of patients undergoing cardiovascular and cerebrovascular interventional therapy, interventional nursing intervention effectively improved the patient’s clinical efficacy, reduced the incidence of complications, reduced negative emotions, improved the quality of life, and increased nursing satisfaction.

Magnesium metal and its corrosion products:Promising materials for tumor interventional therapy

Magnesium is generally known to degrade in aqueous environments by an electrochemical reaction.The corrosion products of magnesium include hydrogen gas,Mg^(2+),and Mg(OH)_(2).Here,we summarize the published literature describing the corrosion characteristics of magnesium,and the antitumor properties of magnesium-associated corrosion products,aiming to induce the therapeutic properties of magnesium and magnesium alloys in solid tumors.The therapeutic potential of corrosion products of magnesium is enormous.Hydrogen gas exhibits antioxidant and anti-inflammatory properties,which amount to potential anti-tumor characteristics.Mg(OH)_(2),which creates a localized alkaline microenvironment,represents a second approach for anti-tumor therapy with magnesium metal.Upregulated concentrations of Mg^(2+)ions in the local tumor microenvironment remodelling are considered a third approach for anti-tumor therapy.Therefore,we speculate about the different physical forms of magnesium that could create an anti-tumor microenvironment upon tumor interventional therapy,a technique that precisely places anti-tumor implants like particles and stents.Finally,we present our viewpoints on the potential use of magnesium in diverse solid tumor therapies to inhibit tumor progression.

Low eradication rate of Helicobacterpyloriwith triple 7-14 days and quadriple therapy in Turkey

AIM:The eradication rate of Helicobacter pylori (H pylori) shows variation among countries and regimens of treatment. We aimed to study the eradication rates of different regimens in our region and some factors affecting the rate of eradication. METHODS:One hundred and sixty-four H pylori positive patients (68 males,96 females;mean age:48±12 years) with duodenal or gastric ulcer without a smoking history were included in the study.The patients were divided into three groups according to the treatment regimens.Omeprazole 20mg,clarithromycin 500mg,amoxicillin 1g were given twice daily for 1 week (Group Ⅰ) and 2 weeks (Group Ⅱ). Patients in Group Ⅲ received bismuth subsitrate 300mg, tetracyline 500mg and metronidazole 500mg four times daily in addition to Omeprazole 20mg twice daily.Two biopsies each before and after treatment were obtained from antrum and corpus,and histopathologically evaluated. Eradication was assumed to be successful if no H pylorus was detected from four biopsy specimens taken after treatment.The effects of factors like age,sex,H pylori density on antrum and corpus before treatment,the total H pylori density,and the inflammation scores on the rate of H pylori eradication were evaluated. RESULTS:The overall eradication rate was 42%.The rates in groups Ⅱ and Ⅲ were statistically higher than that in group Ⅰ (P<0.05).The rates of eradication were 24.5%, 40.7% and 61.5% in groups Ⅰ,Ⅱ and Ⅲ,respectively.The eradication rate was negatively related to either corpus H pylori density or total H pylori density (P<0.05).The median age was older in the group in which the eradication failed in comparison to that with successful eradication (55 yr vs 39 yr,P<0.001).No correlation between sex and H pylori eradication was found. CONCLUSION:Our rates of eradication were significantly lower when compared to those reported in literature.We believe that advanced age and high H pylori density are negative predictive factors for the rate of H pylori eradication.

Adeno-associated virus mediated endostatin gene therapy in combination with topoisomerase inhibitor effectively controls liver tumor in mouse model

AIM:rAAV mediated endostatin gene therapy has been examined as a new method for treating cancer.However, a sustained and high protein delivery is required to achieve the desired therapeutic effects.We evaluated the impact of topoisomerase inhibitors in rAAV delivered endostatin gene therapy in a liver tumor model. METHODS:rAAV containing endostatin expression cassettes were transduced into hepatoma cell lines.To test whether the topoisomerase inhibitor pretreatment increased the expression of endostatin,Western blotting and ELISA were performed.The biologic activity of endostatin was confirmed by endothelial cell proliferation and tube formation assays. The anti-tumor effects of the rAAV-endostatin vector combined with a topoisomerase inhibitor,etoposide,were evaluated in a mouse liver tumor model. RESULTS:Topoisomerase inhibitors,including camptothecin and etoposide,were found to increase the endostatin exPression level in vitro.The over-expressed endostatin, as a result of pretreatment with a topoisomerase inhibitor, was also biologically active.In animal experiments,the combined therapy of topoisomerase inhibitor,etoposide with the rAAV-endostatin vector had the best tumor- suppressive effect and tumor foci were barely observed in livers of the treated mice.Pretreatment with an etoposide increased the level of endostatin in the liver and serum of rAAV-endostatin treated mice.Finally,the mice treated With rAAV-endostatin in combination with etoposide showed the longest survival among the experimental models. CONCLUSION:rAAV delivered endostatin gene therapy in combination with a topoisomerase inhibitor pretreatment is an effective modality for anticancer gene therapy.

Constraint-induced movement therapy enhances angiogenesis and neurogenesis after cerebral ischemia/reperfusion

Constraint-induced movement therapy after cerebral ischemia stimulates axonal growth by decreasing expression levels of Nogo-A,RhoA,and Rho-associated kinase(ROCK)in the ischemic boundary zone.However,it remains unclear if there are any associations between the Nogo-A/RhoA/ROCK pathway and angiogenesis in adult rat brains in pathological processes such as ischemic stroke.In addition,it has not yet been reported whether constraint-induced movement therapy can promote angiogenesis in stroke in adult rats by overcoming Nogo-A/RhoA/ROCK signaling.Here,a stroke model was established by middle cerebral artery occlusion and reperfusion.Seven days after stroke,the following treatments were initiated and continued for 3 weeks:forced limb use in constraint-induced movement therapy rats(constraint-induced movement therapy group),intraperitoneal infusion of fasudil(a ROCK inhibitor)in fasudil rats(fasudil group),or lateral ventricular injection of NEP1-40(a specific antagonist of the Nogo-66 receptor)in NEP1-40 rats(NEP1-40 group).Immunohistochemistry and western blot assay results showed that,at 2 weeks after middle cerebral artery occlusion,expression levels of RhoA and ROCK were lower in the ischemic boundary zone in rats treated with NEP1-40 compared with rats treated with ischemia/reperfusion or constraint-induced movement therapy alone.However,at 4 weeks after middle cerebral artery occlusion,expression levels of RhoA and ROCK in the ischemic boundary zone were markedly decreased in the NEP1-40 and constraint-induced movement therapy groups,but there was no difference between these two groups.Compared with the ischemia/reperfusion group,modified neurological severity scores and foot fault scores were lower and time taken to locate the platform was shorter in the constraint-induced movement therapy and fasudil groups at 4 weeks after middle cerebral artery occlusion,especially in the constraint-induced movement therapy group.Immunofluorescent staining demonstrated that fasudil promoted an immune response of nerve-regeneration-related markers(BrdU in combination with CD31(platelet endothelial cell adhesion molecule),Nestin,doublecortin,NeuN,and glial fibrillary acidic protein)in the subventricular zone and ischemic boundary zone ipsilateral to the infarct.After 3 weeks of constraint-induced movement therapy,the number of regenerated nerve cells was noticeably increased,and was accompanied by an increased immune response of tight junctions(claudin-5),a pericyte marker(a-smooth muscle actin),and vascular endothelial growth factor receptor 2.Taken together,the results demonstrate that,compared with fasudil,constraint-induced movement therapy led to stronger angiogenesis and nerve regeneration ability and better nerve functional recovery at 4 weeks after cerebral ischemia/reperfusion.In addition,constraint-induced movement therapy has the same degree of inhibition of RhoA and ROCK as NEP1-40.Therefore,constraint-induced movement therapy promotes angiogenesis and neurogenesis after cerebral ischemia/reperfusion injury,at least in part by overcoming the Nogo-A/RhoA/ROCK signaling pathway.All protocols were approved by the Institutional Animal Care and Use Committee of China Medical University,China on December 9,2015(approval No.2015 PS326 K).

Early constraint-induced movement therapy affects behavior and neuronal plasticity in ischemia-injured rat brains

Constraint-induced movement therapy is an effective rehabilitative training technique used to improve the restoration of impaired upper extremity movement after stroke. However, whether constraint-induced movement therapy is more effective than conventional rehabilitation in acute or sub-acute stroke remains controversial. The aim of the present study was to identify the optimal time to start constraint-induced movement therapy after ischemic stroke and to explore the mechanisms by which constraint-induced movement therapy leads to post-stroke recovery. Sixty-four adult male Sprague-Dawley rats were randomly divided into four groups: sham-surgery group, cerebral ischemia/reperfusion group, early constraint-induced movement therapy group, and late constraint-induced movement therapy group. Rat models of left middle cerebral artery occlusion were established according to the Zea Longa line embolism method. Constraint-induced movement therapy was conducted starting on day 1 or day 14 in the early constraint-induced movement therapy and late constraint-induced movement therapy groups, respectively. To explore the effect of each intervention time on neuromotor function, behavioral function was assessed using a balance beam walking test before surgery and at 8 and 21 days after surgery. The expression levels of brain-derived neurotrophic factor, nerve growth factor and Nogo receptor were evaluated using real time-polymerase chain reaction and western blot assay to assess the effect of each intervention time. The results showed that the behavioral score was significantly lower in the early constraint-induced movement therapy group than in the cerebral ischemia/reperfusion and late constraint-induced movement therapy groups at 8 days. At 21 days, the scores had significantly decreased in the early constraint-induced movement therapy and late constraint-induced movement therapy groups. At 8 days, only mild pyknosis appeared in neurons of the ischemic penumbra in the early constraint-induced movement therapy group, which was distinctly better than in the cerebral ischemia/reperfusion group. At 21 days, only a few vacuolated cells were observed and no obvious inflammatory cells were visible in late constraint-induced movement therapy group, which was much better than at 8 days. The mRNA and protein expression levels of brain-derived neurotrophic factor and nerve growth factor were significantly higher, but expression levels of Nogo receptor were significantly lower in the early constraint-induced movement therapy group compared with the cerebral ischemia/reperfusion and late constraint-induced movement therapy groups at 8 days. The changes in expression levels at 21 days were larger but similar in both the early constraint-induced movement therapy and late constraint-induced movement therapy groups. Besides, the protein nerve growth factor level was higher in the late constraint-induced movement therapy group than in the early constraint-induced movement therapy group at 21 days. These results suggest that both early(1 day) and late(14 days) constraint-induced movement therapy induces molecular plasticity and facilitates functional recovery after ischemic stroke, as illustrated by the histology. The mechanism may be associated with downregulation of Nogo receptor expression and upregulation of brain-derived neurotrophic factor and nerve growth factor expression.

Characteristics and advantages of adeno-associated virus vector-mediated gene therapy for neurodegenerative diseases

Common neurodegenerative diseases of the central nervous system are characterized by progressive damage to the function of neurons, even leading to the permanent loss of function. Gene therapy via gene replacement or gene correction provides the potential for transformative therapies to delay or possibly stop further progression of the neurodegenerative disease in affected patients. Adeno-associated virus has been the vector of choice in recent clinical trials of therapies for neurodegenerative diseases due to its safety and efficiency in mediating gene transfer to the central nervous system. This review aims to discuss and summarize the progress and clinical applications of adeno-associated virus in neurodegenerative disease in central nervous system. Results from some clinical trials and successful cases of central neurodegenerative diseases deserve further study and exploration.

Effect of medical care linkage-continuous management mode in patients with posterior circulation cerebral infarction undergoing endovascular interventional therapy

BACKGROUND Acute cerebral infarction is a severe type of ischemic stroke that can be divided into anterior circulation cerebral infarction and posterior circulation cerebral infarction(PCCI).PCCI affects the structure of the posterior circulation brain,because posterior part of the brain,which has more complex anatomical structures and more prone to posterior circulation vascular variation.Therefore,improving the prognosis of PCCI patients is necessary.AIM To explore the effect of medical care linkage-continuous management mode(MCLMM)on endovascular interventional therapy(EIT)for PCCI.METHODS Sixty-nine patients with PCCI who received EIT and conventional nursing intervention were selected as the control group,and 78 patients with PCCI who received EIT and MCLMM intervention were selected as the observation group.The incidence of postoperative complications,compliance and disease selfmanagement behavior after six months of intervention,modified Rankin scale(mRS)and Barthel index(BI)scores in the acute phase and after one year of intervention,and recurrence within one year were compared between the two groups.RESULTS The total incidence rate of postoperative complications in the observation group(7.69%)was lower than that in the control group(18.84%)(P<0.05).The scores for medical compliance behavior(regular medication,appropriate diet,and rehabilitation cooperation rates)and disease self-management behavior(self-will,disease knowledge,and self-care ability)in the observation group were higher than those in the control group(P<0.05).After one year of intervention,in the observation group,the mRS score was significantly lower,and the BI score was significantly higher than those in the control group(P<0.05).The recurrence rate within one year in the observation group(3.85%)was significantly lower than that in the control group(13.04%)(P<0.05).CONCLUSION MCLMM can reduce the incidence of complications after EIT for PCCI,improve patient compliance behavior and disease self-management ability,and promote the recovery of neurological function.

Role of interventional therapy in hepatic artery stenosis and non-anastomosis bile duct stricture after orthotopic liver transplantation

AIM： To analyze the clinical manifestations and the effectiveness of therapy in patients with orthotopic liver bansplantation （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 five 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 five 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 significantly beneficial.

Minimally invasive interventional therapy for pain

Pain interventional therapy,known as the most promising medical technology in the 21st century,refers to clinical treatment technology based on neuroanatomy,neuroimaging,and nerve block technology to treat pain diseases.Compared with traditional destructive surgery,interventional pain therapy is considered a better and more economical choice of treatment.In recent years,a variety of minimally invasive pain interventional therapy techniques,such as neuroregulation,spinal cord electrical stimulation,intervertebral disc ablation,and intrasheath drug infusion systems,have provided effective solutions for the treatment of patients with post-herpetic neuralgia,complex regional pain syndrome,cervical/lumbar disc herniation,and refractory cancer pain.
