Objective To compare the efficacy of stenting in the treatment of idiopathic intracranial hypertension(IIH)complicated by different types of venous sinus stenosis(VSS).Methods The clinical data of 48 patients with IIH complicated by VSS,who received stenting therapy at the First Affiliated Hospital of Zhengzhou University of China from January 2019 to September 2023,were retrospectively analyzed.According to the type of VSS,the patients were divided into intrinsic stenosis group(n=20)and the extrinsic stenosis group(n=28).The improvement of symptoms,Frisén grade of papilledema,lumbar puncture opening pressure(LPOP),trans-stenosis pressure gradient(△P)of VSS,and surgery-related complications were compared between the two groups.Results The mean age of the patients in the intrinsic stenosis group was greater than that of the patients in the extrinsic stenosis group(41.60 years vs.35.25 years,P=0.049).The length of the narrowed segment in the extrinsic stenosis group was 22.5 mm,which was significantly longer than 19.0 mm in the intrinsic stenosis group(P=0.007).The postoperative Frisén grade of papilledema in the extrinsic stenosis group was obviously lower than that in the intrinsic stenosis group(P=0.037).No statistically significant differences in the other clinical data existed between the two groups(all P＞0.05).After stenting,all of the median △P,mean LPOP,and median Frisén grade of papilledema were decreased significantly when compared with their preoperative values(all P＜0.001),and the postoperative 3-day median Frisén grade of papilledema in the extrinsic stenosis group was much lower(P=0.037).The patients were followed up for one year,the clinical symptoms of the patients in both groups were improved to varying degrees.At the time of discharge,the proportion of patients having no symptoms of papilledema in the extrinsic stenosis group was 57.1％,which was higher than 22.2％in the intrinsic stenosis group(P=0.049),and no statistically significant differences in the improvements of other symptoms existed between the two groups(all P＞0.05).There was no significant difference in the incidence of complications between the two groups(P=0.563).Conclusion Venous sinus stenting can effectively treat patients with IIH complicated by different types of VSS.

Objective To compare the clinical efficacy of medication and stenting in treating patients with idiopathic intracranial hypertension complicated by venous sinus stenosis.Methods The clinical data of 74 patients with idiopathic intracranial hypertension complicated by venous sinus stenosis,who were admitted to the First Affiliated Hospital of Zhengzhou University of China from January 2020 to June 2023,were retrospectively analyzed.The patients were divided into medication group(n=35,receiving drug therapy)and stenting group(n=39,receiving stent implantation therapy).Before and after treatment,lumbar puncture and fundus examinations were performed,and the postoperative improvements in intracranial pressure and papillary oedema were evaluated.The changes in the median papillary oedema Frisén grade and the average opening pressure of lumbar puncture were compared between the two groups during hospitalization period.The improvement degrees of the clinical symptoms determined at discharge,as well as at the 6 months and 12 months after discharge were compared between the two groups.The incidence of complications during the follow-up period in the two groups was recorded.Results The time interval from onset to treatment in the stenting group was longer than that in the medication group(2 months vs.one month,P=0.021),and the differences in the other baseline data between the two groups were not statistically significant(all P＞0.05).After treatment,different degrees of improvement were obtained in both groups(all P＞0.05).At the time of discharge,the degree of median papillary oedema in the stenting group was Frisén grade I,which was lower than Frisén grade Ⅱ in the medication group(P=0.011);the average opening pressure of lumbar puncture in the stenting group was 205.26 mm H2O,which was lower than 248.14 mm H2O in the medication group(P=0.002).The proportions of patients having no symptom or showing symptom improvement in the stenting group and in the medication group at the time of discharge were 74.4％and 45.7％respectively(P=0.017),which at the time of 6 months after discharge were 84.6％and 48.6％respectively(P=0.001)and at the time of 12 months after discharge were 87.2％and 57.1％respectively(P=0.004).No statistically significant difference in the incidence of complications existed between the two groups(10.3％and 8.6％respectively,P=1.000).Conclusion For the treatment of patients with idiopathic intracranial hypertension complicated by venous sinus stenosis,stent implantation therapy is superior to medication therapy in quickly and effectively relieving papillary oedema,decreasing lumbar puncture opening pressure,and improving their corresponding symptoms and signs,with satisfactory patient's prognosis and clinical safety.

Objective:To investigate the effect of regional leptomeningeal collateral circulation (rLMC) score based on CT angiography (CTA) and onset-to-reperfusion time (OTR) on the outcome after endovascular treatment (EVT) in patients with anterior circulation acute large vessel occlusive stroke (ACA-LVOS).Methods:Patients with ACA-LVOS underwent EVT in the Department of Neurology, the Affiliated Hospital of Yangzhou University from July 2017 to July 2023 were included retrospectively. The rLMC score 0-10 was defined as poor collateral circulation, and 11-20 were defined as good collateral circulation. At 90 days after EVT, the modified Rankin Scale (mRS) was used to evaluate the outcome. A score of 0-2 was defined as a good outcome and 3-6 were defined as a poor outcome. Multivariate logistic regression analysis was used to determine the independent influencing factors of the outcome after EVT. Results:A total of 144 patients with ACA-LVOS underwent EVT were enrolled, including 78 males (54.2%), median aged 73 years. The median baseline National Institutes of Health Stroke Scale (NIHSS) score was 16, the median baseline Alberta Stroke Program Early CT Score (ASPECTS) was 9, and the median OTR was 330.5 minutes. Eighty patients (55.6%) had good collateral circulation, 63 (43.8%) had poor outcome, including 13 deaths. Univariate analysis showed that there were significant differences in hypertension, previous stroke history, smoking, triglycerides, baseline NIHSS score, baseline ASPECTS, OTR, and collateral circulation status between the good outcome group and the poor outcome group (all P<0.05). Multivariate logistic regression analysis showed that good collateral circulation (odds ratio [ OR] 0.223, 95% confidence interval [ CI] 0.077-0.643; P=0.005) was an independent predictor of good outcome. In the poor collateral circulation group, longer OTR was an independent predictor of poor outcome ( OR 1.020, 95% CI 1.008-1.032; P=0.001). In the good collateral circulation group, longer OTR was not an independent risk factor for poor outcome ( OR 1.005, 95% CI 1.000-1.010; P=0.062). Conclusion:rLMC score based on CTA and OTR are the independent predictors of the outcome after EVT in patients with ACA-LVOS.

Objective To compare therapeutic efficacy of anticoagulation alone and combining with intervention for treating severe cerebral venous thrombosis(CVT).Methods Data of 65 severe CVT patients were retrospectively analyzed.The patients were divided into anticoagulation group(n=32)or combined group(n=33)according to therapeutic methods.The modified Rankin scale(mRS)score at admission and discharge,the prognosis of patients,vascular recanalization rate as well as incidence of complications during follow-up period were compared between groups.Results No significant difference of mRS scores at admission was found between groups(P＞0.05),while mRS scores of combined group were lower than of anticoagulation group at discharge(P＜0.05).The rate of good prognosis at discharge(84.85%vs.59.38%),6 months after discharge(87.88%vs.65.63%)and 12 months after discharge(93.94%vs.75.00%)in combined group were all higher than those in anticoagulation group(all P＜0.05).The vascular recanalization rate in combined group was higher than that in anticoagulant group(100%vs.75.00%,P＜0.05).At the end of follow-up,no significant difference of complication incidence was found between groups(15.15%vs.18.75%,P＞0.05).Conclusion For patients with severe CVT,anticoagulation combined with interventional therapy could significantly alleviate clinical symptoms and improve prognosis compared with anticoagulation alone.

Objective To observe the value of stent implantation for treating idiopathic intracranial hypertension(IIH)complicated with venous sinus stenosis(VSS).Methods Data of 54 patients with IIH complicated with VSS who underwent stent implantation were retrospectively analyzed.The papillary edema grade,lumbar puncture-opening pressure(LP-OP)and trans-stenotic pressure gradient of venous sinus(ΔP)before and after stent implantation were compared,and the symptom improvement and treatment-related complications during the follow-up period were recorded.Results Totally 60 stents were successfully implanted in 54 patients.Before stent implantation,the papillary edema grade was 3(3,3),LP-OP was(391.39±92.62)mmH2O and the ΔP was 18.50(15.00,25.00)mmHg,which decreased to 1(0,1),(208.80±62.31)mmH2O and 1.25(0.88,2.55)mmHg after stent implantation,respectively,all with significant differences(all P＜0.001).Clinical symptoms improved after stent implantation in all 54 patients.At the end of follow-up,disappearance of headache,papillary edema,visual disorder,abducent nerve paralysis and tinnitus were noticed in 30(30/37,81.08%),38(38/45,84.44%),41(41/45,91.11%),8(8/10,80.00%)and 9 cases(9/10,90.00%),respectively.Treatment-related complications occurred in 4 cases(4/54,7.41%),all improved after intervention.Conclusion Stent implantation was effective and safe for treating IIH complicated with VSS.

Objective:To explore whether the comprehensive scoring method of postoperative pain management quality can effectively evaluate the quality of postoperative pain management in hospitals or departments.Methods:Using the purposive sampling method and the convenient sampling method, a total of 9 Orthopedic Departments of 9 hospitals in Zhejiang Province and Jiangsu Province from January to May 2018 were selected as the research objects. According to whether it was a painless ward certified by the hospital, they were divided into the painless ward group (4 departments) and the non-painless ward group (5 departments). The postoperative pain management quality comprehensive scoring method, the weighted rank sum ratio method and the weighted TOPSIS method were used to calculate the scores and rankings of each department. The score differences of different groups were compared, and the correlation analysis of the ranking results of different evaluation methods was carried out.Results:The total score of the first-level index of pain management comprehensive scoring method and the scores of all dimensions in the painless ward were higher than those of the non-painless ward, and the differences were statistically significant (all P<0.05). The scores of environmental and materials, system/guidelines/procedures, pain assessment, analgesia treatment, and analgesic effect in the secondary indicators of pain management comprehensive scoring method in painless wards were higher than those of non-painless wards, and the differences were statistically significant (all P<0.05). The results of three methods for evaluating quality of postoperative pain management in the department were not all the same, but they were positively correlated. The correlation coefficients of postoperative pain management quality comprehensive scoring method, the weighted TOPSIS method and the weighted rank sum ratio method were 0.933 and 0.833 (all P< 0.01) . Conclusions:The comprehensive scoring method of postoperative pain management quality can effectively reflect the pros and cons of postoperative pain management quality in hospitals or departments.

Objective:To investigate the CT features of lung injury induced by paraquat poisoning and its relationship with prognosis, and to provide reference for the judgment of the condition and prognosis of paraquat poisoning.Methods:146 cases of paraquat poisoning patients were treated in the Third People's Hospital of Xuzhou City from January 2013 to April 2016. The cases were divided into mild group, moderate-severe group and fulminant group according to the concentration of paraquat in urine. The clinical data and CT imaging findings were analyzed and reconstructed in three-dimensional reconstruction. The extent of the lesion was observed and the relationship between CT and prognosis was explored.Results:Paraquat lung injury has many manifestations on CT images, and it's performance can be intersecting at the same time. Early lesions lighter cases, late CT imaging lesions can be completely absorbed or residual fibrosis, the prognosis was good; the early lesion was pulmonary consolidation, pleural effusion cases, the late CT image was usually pleural thickening and bronchiectasis, the prognosis was relatively good; early lesions were large patches of ground glass opacity cases, finally, pulmonary fibrosis was common, the mortality rate of 56.57%. There were significant differences in the extent of lung injury between different groups ( P<0.001) , and the difference in mortality was statistically significant when the lung injury was different ( P<0.001) . Multivariate stepwise Logistic regression analysis showed that ground-glass opacity ( OR value=2.013) , interstitial lung fibrosis ( OR=3.779) and mediastinal emphysema ( OR=33.118) were risk factors for death of lung injury caused by paraquat poisoning ( P<0.05) . Conclusion:There were many manifestations on CT images of paraquat lung injury, and the manifestations of paraquat lung injury can be intersecting at the same time. The pulmonary manifestations and outcomes of different paraquat types were different. The CT manifestations of lung injury in paraquat poisoning were mainly exudative changes at early stage, and can be gradually absorbed or evolved into interstitial changes at later stage. The cumulative damage range can be used as a reference for evaluating the prognosis. Ground-glass opacity, interstitial pulmonary fibrosis and mediastinal emphysema are the risk factors for death of lung injury caused by paraquat poisoning.
