Interventional radiology possesses the character of tiny wound and conforms to the modern tide of medical development with wide prospect. There are different developmental modes appearing in these years,no matter what they are,but we persist in the opinion that interventional radiology is a new developing clinical subject,neither a purely medical technology nor an adjunct for clinical subjects. Specialization,standardization and clinicalization are the inevitable key developmental way for interventional radiology. Interventional department of the people's hospital of Henan Province gives a successful mode and prospect for all colleagues to refer and think over.

During the past decades, interventional neuroradiology has become one of the most important modalities for treatment of cerebral vascular diseases. Chinese doctors have made great progress in this field, and their diagnosis and treament have also reached the international level in some territories. Following the need of specialized development for interventional neuroradiology,more and more problems have arisen and even caused argument in this field. To resolve the issue and promote the healthy and fast development of interventional neuroradiology,it is time for us to formulate the standard training and certification system for interventional neuroradiologist.

Subacute and chronic cerebrovascular occlusion is an uncommon but an important cause for ischemic stroke.The main pathogenic mechanism is local hemodynamic disorder.Theoretically,the improvement of hemodynamic disorder can reduce the incidence of stroke as well as improve the prognosis.At present,there is still controversy over the optimal therapeutic plan.With the rapid development of interventional techniques,considerable progresses have been made in the endovascular treatment for subacute and chronic cerebrovascular occlusion,although some shortcomings still exist.This article aims to make a comprehensive review about the subacute and chronic cerebrovascular occlusion,focusing on its definition,damage,clinical status of its treatment,imaging evaluation,technical points of endovascular therapy,and procedure-related complications.

Objective To explore the interventional methods to treat recurrent jaundice after palliative bilio intestinal anastomosis in patients with malignant obstructive jaundice due to cholangiocarcinoma. Methods Ten patients with recurrent jaundice after bilio intestinal anastomoasis were retrospectively evaluated. Nine of ten underwent PTCD with metallic stent placement, one underwent the inner outer draining catheter procedure. The patients were evalualed with comparison in regard to preoperative conditions, TBIL,ALT,GTP and AKP values.Results Stent placement was successful only once in all 10 cases with successful rate of 100%. TBIL,ALT,GTP and AKP values were significantly lower 7 days postoperative by than that preoperation. Subsidence of jaundice was satisfactory for 100% in all patients after the treatment. Conclusions Percutaneous placement of biliary metallic stents is a safety, simple, low complication method for managing recurrent jaundice after palliative bilio intestinal anastomosis for the terminal stage of malignant obstructive jaundice.

ObjectiveTo observe the effect of acupuncture plus language function training on the recovery of language function in patients with post-stroke aphasia.MethodNinety patients were divided into an acupuncture-rehabilitation group (intervened by acupuncture plus language function training) of 30 cases, an acupuncture group (intervened by acupuncture alone) of 30 cases, and a control group (intervened by language function training alone) of 30 cases. The Western Aphasia Battery (WAB) was adopted to evaluate the language function, and also taken as criteria for diagnosis and therapeutic efficacy. The aphasia quotient (AQ), and the 4 basic language functions including spontaneous speech, auditory comprehension, repetition and nomination were observed. ResultAfter intervention, AQ, and scores of spontaneous speech, auditory comprehension, repetition and nomination increased significantly in the three groups (P<0.05,P<0.01). there were significant differences in comparing the scores of spontaneous speech, repetition and nomination between the acupuncture-rehabilitation group and the control group (P<0.05). There were no significant differences in comparing the indexes between the acupuncture group and control group (P>0.05).ConclusionAcupuncture plus language function training can produce a positive effect on patients with post-stroke aphasia, showing therapeutic advantage in improvingspontaneous speech, repetition, and nomination.

Objective To evaluate the clinical efficacy of endovascular embolization with detachable balloon, based on the characteristics of traumatic carotid-cavernous fistulae (TCCF), in treating TCCF. Methods The clinical data of 188 patients with TCCF, who had received endovascular embolization with detachable balloon via femoral artery access, were retrospectively analyzed. The risk factors for recurrence were statistically analyzed. Results Of the total 188 patients, complete cure after the first balloon embolization was obtained in 160, certain improvement of clinical symptoms was achieved in 22, and balloon embolization failed in 6, for whom other surgical options had to be carried out. Complications occurred in three patients. Recurrence was seen in 23 patients within the period from one day to 5 years after the treatment, and the recurrent lesion was successfully cured in all patients. Univariate analysis and chi square test or correction chi square test indicated that factors affecting postoperative recurrence were the use of multiple balloons for embolization and the presence of residual fistula after operation (P<0.05), while patient’s sex, age, duration of disease showed no statistically significant correlation with the recurrence (P>0.05). Multivariate logistic regression analysis revealed that the independent factors affecting recurrence included the number of used balloon≥2 (OR=7.80, 95%CI:2.28-26.73,P=0.001) and postoperative residual fistula that was observed immediately after the embolization (OR=10.46, 95%CI:2.99-36.50,P=0.000). Conclusion For the treatment of TCCF, transcatheter embolization with detachable balloon is minimally-invasive, safe and reliable with fewer complications, therefore, this technique should be regarded as the therapy of first choice. The use of multiple balloons and the presence of residual fistula observed immediately after the embolization procedure are the risk factors for recurrence. Other possible risk factors are still to be furtherstudied.

Along with the continuous publication of a series of large-scale clinical trials results,endovascular thrombolytic therapy (or combined with intravenous thrombolysis) has been recommended as the treatment of first choice for acute ischemic stroke caused by large intracranial artery occlusion.Nevertheless,there are a variety of factors that may affect the clinical outcome of endovascular recanalization procedure.This article aims to make a comprehensive review about the factors that may affect the prognosis of patients with acute ischemic stroke who are receiving endovascular treatment.

Aim To investigate the roles of FFJ-5 in human breast cancer MCF7 cells and drug-resistant MCF7/DOX cells and to explore its mechanisms. Methods MTT assay was used to detect the effect of FFJ-5 on MCF7 and MCF7/DOX cell proliferation and sensitivity of doxorubicin in MCF7/DOX cells.West-ern blot was used to investigate the effect of FFJ-5 on expression of EGFR,p-EGFR,Akt,p-Akt,PKM2, cleaved caspase-3,cleaved PARP and P-gp.DNA lad-der analysis was performed to determine the effect of FFJ-5 on genomic DNA.RT-PCR was performed to de-tect the influence of FFJ-5 on multidrug resistance gene MDR1 mRNA levels.Results The results showed that FFJ-5 inhibited the growth of MCF7 ,inhibited the expression and activity of EGFR and Akt,and conse-quently reduced the expression of PKM2 in MCF7 cells;FFJ-5 activated caspase-3 and induced genomic DNA fragmentation;FFJ-5 also inhibited the growth of MCF7/DOX cells and enhanced the anti-tumor activity of doxorubicin in MCF7/DOX cells.Conclusion The results suggest that FFJ-5 could inhibit MCF7 cell growth and induce MCF7 cell apoptosis through inhibi-tion of EGFR-Akt-PKM2 pathway and activation of ap-optosis-related factors caspase-3 , meanwhile FFJ-5 could also reverse the resistance of MCF7/DOX.

ObjectiveTo explore efficacy,durability and possible impacts on life quality of carotid occlusion treatment to carotid cavernous fistula (CCF) patients.MethodsCCF patients since 2001 were retrospectively analyzed,the clinical features,2 weeks post procedure mRS score and ratio of carotid occlusion were recorded.Headache impact test (HIT-6) and Short form health survey(SF-36) were used to assess impact of sequelae in patients' daily life,by phone call,questionnaire and clinic recheck.Results Total 96 cases were studied composed of 81 direct CCF and 15 dural AVF.Thirty-two direct CCF cases underwent carotid occlusion during procedure and many ophthalmologic signs but visual impairment got recovery after 2 weeks,the mRS score less than 2 were revealed.The one year post operation HIT-6 score more than 50 was more likely found in carotid occlusion cases comparing with those preserved carotid artery while the 3 year SF-36 scores of carotid occlusion cases revealed inferior to those with patent artery,especially in body pain,general health and vitality subscales.ConclusionCarotid occlusion seems to be a feasible,effective and durable alternative for CCF treatment,but which could play a negative role on quality of patients' life in the long run.

Objective To discuss the clinical application of medical coordination and hierarchical responsibility system in interventional nursing care which is carried out based on the “Henan Province Model”. Methods From November 2003 to April 2014 at authors’ hospital, medical coordination and hierarchical responsibility system was executed through setting up a ranking system of nursing position , optimizing shift process , dividing physician-nurse medical liability groups , strengthening medical training , implementing medical coordination service mode, etc. The clinical results were compared with those of conventional nursing care that were recorded during the period from May to Oct. of 2013. Results After implementation of medical coordination and hierarchical responsibility system, the quality of medical care, the patent’s satisfaction, the cooperation satisfaction of physicians and nurses were significantly improved. Compared with those before implementation of medical coordination and hierarchical responsibility system , the differences in the above indexes were statistically significant(P<0.01 or P<0.05). Conclusion Based on multidisciplinary joint diagnosis and treatment, and combined with coordination physician-nurse service mode, the enthusiasm of nursing staff can be motivated and the tacit understanding between physicians and nurses as well as the quality of nursing service can be improved. All of the above will promote the development of nursing discipline.
