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.

To observe the use of group 19 cases of 2 holes,19 cases 3 holes were adopted in the control group.Pull the chest tube operation time,operation time of the two groups were compared after.and the average hospitalization time after opera-tion,postoperative analgesia drug application.Results The observation group operation time,operation time,pulling the chest tube after operation the average hospitalization time, analgesic drug application rate respectively were (46.89 ±9.11)min,(3.95 ±0.85) d,(7.37 ±1.34) d,21.1%,The control group were (66.05 ±12.09) min, (4.37 ±0.98)d,(7.32 ±1.57)d,52.6%.There were statistically significant differences in rate of the two groups in operation time,analgesic drug application.(t=-5.516,χ2 =4.071,P<0.05);38 cases were cured,followed up for 3-24 months,no recurrence occurred in 1 cases.Conclusion Video assisted thoracic descending congenital pulmona-ry bulla resection,the 2 hole 3 hole more than minimally invasive,short operation time,postoperative analgesic use rate is low.

Objective To investigate the clinical feature of perioperative management of non-small cell lung cancer(NSCLC) in aged patients and improve the efficacy of surgical treatment.Methods The clinical data of 35 aged patients with NSCLC were retrospectively analyzed.The risk factors of postoperative complications were analyzed by single factor analysis,the factors had statistical significance were included in Logistic regression analysis.Results Postoperative complications occurred in 10 cases,accounting for 28.6％,and 1 case died,accounting for 2.9％.Logistic regression analysis showed that smoking,chronic bronchitis,coronary heart disease,pulmonary lobectomy were independent risk factors of postoperative complications.ConCLusion Correct staging before operation,strict surgical indication,choose the standard surgical method to reduce surgical trauma,strengthen the perioperative management can still achieve satisfactory therapeutic effect in surgical operation for aged patients with NSCLC.

Objective To assess the safety, feasibility, short-and mid-term efficacy of wingspan stent for treating patients with symptomatic intracranial artery stenosis. Methods A total of 113 patients with severe symptomatic intracranial stenosis were enrolled and Gateway-wingspan stenting were performed on all patients. The technical success, the pre- and post-stenting stenosis, perioperative complications, clinical outcome and restenosis rates were recorded, and chi-square test was used for analysis of complication rate by comparing our results with the results of Warfarin-Aspirin Symptomatic Intracranial Disease (WASID) study and NIH multi-center Wingspan stenting trial. Results The technical success rate was 99. 1% ( 112/113). The mean pre and post-stent stenoses were (80.7 ± 9.3)% and (27.7 ± 9.7)% (χ2 =9.397,P < 0. 05 ). The total complication rate was 4.4% (5/113 ) during the follow-up ( mean 14. 5 months, range 1-28 months), and the frequency of restenosis was 12. 5% (5/40) at 6 months. The primary endpoint events, ischemic stroke, and lesion-related ischemic stroke were lower in our study (4.5%, 3.5%,3.5% ) compared with the results of WASID trial (21.1%, 20. 4%, 15.0% ,P<0. 05). For those with poor outcome in the three high-risk sub-groups which were with more than 70% stenosis, or last event from the treatment was less than 17 days, or NIHSS was above 1, a better outcome was observed in our group (4. 5% ,4. 7% and 2. 0% in our study, 19.0%, 17.0% and 19. 6% in previous study, P < 0. 05). The medium-term efficacy in this group (4. 5% ) significantly improved compared with NIH study ( 14. 0% ,P <0. 05 ). Conclusions Wingspan stenting for symptomatic intracranial arterial stenosis is with good safety,feasibility and low perioperative stroke rate and mortality. The incidence of primary endpoint events and the ischemic events are lower than those of medication group, and the efficacy of stenting is significantly better than medication even in high-risk population.

Objective To explore the causes of upper gastrointestinal rebleeding after devascularization operation for portal hypertension and the therapeutic effect of shunt operation.Methods The clinical data of 56 cases of upper gastrointestinal rebleeding after devascularization operation for portal hypertension in our hospital from 1996 to 2006 were retrospectively analyzed.Shunt operation was done in 54 ceses including emergency operation shunt in 5 cases,and elective operation in 49 cases.C-type Mesocaval shunt was done in 45 cases,inferior mesenteric vein-cava shunt in 4 cases,H-type and portacaval in 5 cases.Results Chylorrhea occurred in 13 cases after operation and all recovered;hepatic encephalopathy occurred in 5 cases,and 4 cases recovered,1 died;and 1 case died of liver function failure on the third day after operation.Fifty-two cases were followed-up from 6 months to 9 years,and none had recurrence of upper gastrointestinal bleeding,but 7 died(2 cases died of primary hepatic carcinoma,3 cases died of liver function failure and hepatic encephalopathy,and 2 cases died of non-correlated disease).Conclusions Patients with upper gastrointestinal rebleeding after devascularization operation for portal hypertension should undergo non-operative treatment at first,and elective surgery is done later.If aggressive non-operative treatment for 48h is not successful,then emergency operation should be performed.In elective cases,the operation of first choice is mesocaval interposition synthetic graft shunt,which is particularly applicable in patients with portal vein thrombosis or portal hypertensive gastropathy.

Objective To evaluate the mid-and long-term follow-up outcome of revascularization and stenting of nonacute intracranial vertebrobasilar artery occlusion. Methods Consecutive data of 27 patients who suffered from nonacute intracranial vertebrobasilar artery occlusion beyond 24 hours and underwent endovascular revascularization, were retrospectively collected and analyzed. Complications and recurrent ischemic events during the follow-up period were recorded. The modified Rankin scale(mRS) scores were used and compared between pre-and postoperation. Results All 27 patients except one(96.3%) obtained successful recanalization. After the procedure, 13 patients showed improvement, 11 were stable, and 3 worse. The decline of median mRS scores, which was 4(interquarter range-IR, 2-5) preoperatively and 3(IR, 1-5) on discharge. Five patients suffered from procedural complications and three of them resulted in aggravation. Nineteen patients received imaging follow-up during the median 10 months, 6 restenosis occurred and 3 of them were symptomatic. During median 55 months clinical follow-up after operation, 2 ipsilateral stroke and 2 ipsilateral transient ischemic attack occurred. The mRS scores decreased significantly in the first one year after procedure. Conclusions Revascularization and stenting of nonacute intracranial vertebrobasilar artery occlusion can prevent recurrent ipsilateral ischemic event and improve disability recovery in the first one year.

Objective To investigate the effect of interventional therapy for Budd Chiari Syndrome(BCS). Methods 355 patients with BCS were examined with phlebography of inferior vena cava(PIVC) and percutaneous transhepatic hepatovenography(PTHV).The interventional procedures were based on the pathological changes of inferior vena cava(IVC) and main hepatic veins(MHVs).The procedures included PTA and/or stent placement of IVC,percutaneous transhepatic recanalization and dilation (PTHRD)of MHVs ,and percutaneous transjugular or transinferior vena cava recanalization and dilation with stent placement of MHVs(PTJRD and PTIRD ), percutaneous transhepatic recanalization or transinferior vena cava recanalization and dilation with stent placement of associated hepatic veins(AHVs). Results The success rate and recurrence rate were 96.0%(240/250) and 10.0 %(24/240), respectively, in PTA; the success rate was 91.4%(32/35 ) in PTHRD of MHVs; 90.0%(18/20 ) in PTJRD and PTIRD of MHVs , 100.0%(10/10) in PTJRD and PTIRD of AHVs; 90.0 %( 9/10 ) in PTA and stent placement plus PTHRD of AHVs. Severe complications occurred in 10 cases (2.8%). Conclusions Interventional therapy is simple, safe and effective for patients with some types of Budd Chiari Syndrome.

Objective:To investigate the effect of thrombus burden on the clinical outcome of endovascular recanalization in large vessel occlusive stroke.Methods:Patients with acute anterior circulation occlusion who underwent endovascular treatment within 24 hours after onset in Zhengzhou University People′s Hospital from January 2018 to December 2019 were retrospectively collected. According to the clot burden score (CBS) of DSA, total objectives were divided into CBS≥6 group (24 cases) and CBS<6 group (38 cases). Clinical data of the two groups were collected and the modified Rankin scale (mRS) was used to evaluate the clinical outcome at 90 days after surgery. Independent sample t-test, Wilcoxon rank sum test and χ 2 test were used to compare the clinical data between the two groups. Independent risk factors affecting the clinical outcome were analyzed by binary logistic regression. Results:There were no statistically significant differences in basic demographic data, stroke risk factors and other factors between the CBS≥6 group and CBS<6 group ( P>0.05).The proportion of using tirofiban after surgery in the CBS≥6 group (63.2%, 24/38) was lower than that in the CBS<6 group (87.5%, 21/24) (χ2=4.380, P=0.044). The discharge NIHSS score of the CBS≥6 group was [5.0 (3.3, 7.8) points] lower than CBS<6 group [8.5 (1.8, 14.5) points] ( Z=5.221, P=0.022). The proportion of postoperative mRS 0-2 was (91.7%, 22/24) in the CBS≥6 group higher than CBS<6 group(39.5%, 15/38) (χ2=20.486, P=0.001), there were no statistically significant differences between the two groups ( P<0.05). The results of binary logistics regression analysis showed the CBS groups (OR=0.042, 95%CI 0.007-0.244 , P=0.001) was an independent risk factor affecting good outcome. Subgroup analysis of whether tirofiban was used or not showed there was no statistically significant difference in clinical prognosis between the two groups ( P>0.05). Conclusions:The clinical outcome of CBS≥6 group is significantly better than that of CBS<6 group, and patients with small thrombus burden are more likely to get a good clinical outcome of 90 days.

Objective To compare the perioperative complications of prophylactic use of three antiplatelet strategies in unruptured intracranial aneurysms treated by stent assisted coiling. Methods A total of 203 consecutive patients were brought into this retrospective study including the following three groups:the loading group (n=54), with a loading dose of 300 mg to 600 mg clopidogrel at 2 h to 24h before the stenting; tirofiban group (n=50), a loading dosage of tirofiban (8 μg/kg/min over 3 min) followed by a 0.1μg/kg/min maintenance dosage; dual antiplatelet group (n=99), dual oral antiplatelet drugs (clopidogrel 75 mg + aspirin 100 mg) pretreated for 3-5 days before the operation. Events of hemorrhage and thromboembolism were recorded and the complications were compared to assess the safety and efficacy of various antiplatelet strategies. Chi-square or Fisher exact tests were used for categorical variables. Results The hemorrhagic rates were 11.1% in loading group, 2.0% in dual antiplatelet group, and 0% in tirofiban group, respectively, while the thromboembolic rates were 7.4% in loading group, 4.0% in dual antiplatelet group, and 0% in tirofiban group, respectively. For total complications, significant difference (P<0.05) existed among the three groups, and the complication rate in loading group was significantly higher than that of the dual group (P=0.016) and tirofiban group (P=0.001), while there was no significant difference between tirofiban group and dual antiplatelet group(P>0.05). The hemorrhagic rate in loading group was significantly higher than that of the dual group (P=0.023) and tirofiban group (P=0.027), while there was no significant difference between tirofiban group and dual antiplatelet group (P>0.05). In subgroup analysis of the loading group, the postoperative thromboembolic rate was significantly higher in those exposed to low molecular weight heparin than those not (P=0.039) with no increase of hemorrhagic events (P>0.05). Conclusions When compared with the dual antiplatelet strategy, tirofiban strategy may be used as a new prophylactic protocol in unruptured intracranial aneurysms treated by stent assisted coiling. Those treated by low molecular weight heparin postoperatively after receiving dual antiplatelet therapy may increase the hemorrhagic risk, although there was a significant decrease in thromboembolic events postoperatively.

Objective To summarize the important role of guiding road in treatment of carotid artery lesion by covered stent.Methods From January 2013 to October 2014,the consecutive data were collected from 10 patients with carotid artery lesions treated with covered stents,including 8 of aneurysms,one of traumatic pseudoaneurysm and one of recurrent carotid cavemous fistula.For 5 lesions with straight carotid artery path,the use of conventional 6F Envoy guiding catheter path was established,or the introduce sheath itself was used as guiding catheter;for 4 lesions with tortuous carotid artery path,Neuron070 guiding catheters and 70 cm 7-French reinforced long introduce sheath was used to establish guiding road;for one ophthalmic artery lesion with tortuous carotid artery path,conventional 6F Envoy guiding catheter was used to establish guiding road.The established guiding roads were followed by navigation of covered stent.Hunt-Hess scale was performed to evaluate the neurological functions before operation,immediate post-operation and one week after surgery.Results Except for the guiding road for one of ophthalmic artery aneurysm with tortuous carotid artery path,the remaining covered stents in the 9 patients successfully reached the lesions.All covered stents were successfully deployed in the patent arteries across the lesions,the lesions were cured immediately without contrast agent filling;the cure rate reached 90％.Hunt-Hess scale score was 0 in 9 patients before operation,immediate post-operation and one week after surgery;that was one in one subarachnoid hemorrhage patient.Conclusions A good guiding road is the key to reach the carotid artery lesion for covered stent.Usage of Neuron070 guiding catheter and reinforced long introduce sheaths can significantly extend the scope of application of the covered stent in tortuous carotid artery lesions.
