Objectives:We investigated and studied the incidence of depression in the wake of cerebral infarction Methods:Self-rating Depression Scale (SDS) and Hamilton Depression Scale (HAND) were evaluated and tested among 210 patients of cerebral infarction, and at the same time a contrast was made among 50 normal persons At the patients were divided into two groups, one suffered from depression and the other not suffered from depression Then they were compared Results:The depressive mood of the patients of cerebral infarction was obviously higher than those of normal group In this thesis, the incidence of cerebral infarction with depression is 58% The incidence of this disease was higher among the patients with depression history, females and those who lived apart from one's family Conclusions:The incidence of cerebral infarction with depression is comparatively high, so it should be taken seriously by the clinical doctors

Agonists of peroxisome proliferator-activated receptor gamma (PPARgamma) are of interest as a treatment of type II diabetes, and indenone derivatives are a new class of non-TZD PPARgamma agonists. Based on existing indenone derivatives, a series of novel ones have been designed and synthesized. Meanwhile the structures have been comfirmed with 1H NMR and MS. Among them, 17b and 19 showed higher agonistic activities than rosiglitazone.

Objective To identify the prognosis factors of the patients with high-degree carotid artery stenosis and evaluate the effect of different therapy prospectively.Methods A hundred and three patients with spoke or tansient ischemic attack(TIA)suffering from severe carotid artery stenosis were included into this study consectively.They were given intra-artery intervention or antiplatelet therapy based on clinical factors and the intension of the patients or their Legally Autllorized Representative (LAR)and thus divided into 2 groups.Forty patients were transplanted with stent,63 were given only with antiplatelet drugs.The major outcome of end-point was the 2-year functional prognosis evaluated by modified Rankin score(mRS),while the minor one was the cardiovascular events in 1 year.2 year or longer after the index stroke or TIA,which was defined as stroke,TIA,acute myocardic infarction(AMI)and sudden death in this study.Results There were no statistical significances of sex,years,medical histories,blood pressure, total cholesterol,triglyceide in two groups at baseline.For the major outcome,intra-artery intervention was an independent protective factor for impaired function(mRS 3-6)with the method of binary Logistic(RR= 0.13,P=0.001,95%CI 0.036-0.460).For the minor outcome,the incidence of the cardiovascular events in 1 year and 2 year after the index stroke or TIA was lower in the intra-artery intervention group than in the antiplatelet therapy(For 1 year follow up,intervention group:antiplatelet therapy group= 12.5%:42.9%,OR=0.19,95%CI 0.07-0.55,P=0.001;For 2 year follow up,17.5%:47.6%,OR =0.23,95%CI 0.09-0.60,P=0.002).The median time of cardiovascular events in the two groups was further investigated in 55 months and 54 months separately. Kaplan-Meier analysis showed no significant difference.Survival analysis with Cox-regression showed that neither therapy of intra-artery intervention nor antiplatelet therapy was an independent factor for the cardiovascular events(RR=1.063,95%CI 0.40- 2.83,P=0.900).Conclusions For the stroke or TIA patients suffering from high-degree carotid artery stenosis,intra-artery intervention is superior pure drug therapy in achieving better theapeutical effect and reducing the incidence of the cardiovascular events after the index stroke or TIA.However,its long term effect needs further study.

BACKGROUND:The self-expanding Smart nitinol stent system is a popular treatment for carotid artery stenosis, because it is easy to manipulate and deploy, and endothelialization is rapid. OBJECTIVE:To assess the efficacy of Smart nitinol stent system for the treatment of severe atherosclerotic carotid stenosis. METHODS:We conducted a retrospective, single-center, non-randomized, paral el control ed trial. A cohort of 103 patients with severe atherosclerotic carotid stenosis was included in the analysis after obtaining written informed consent from participants or their guardians. Treatment was undertaken according to each patient’s wishes after weighing the options:a Smart nitinol stent system (Cordis Corporation, Miami, FL, USA) was used in 40 patients, while 63 were managed conservatively with antiplatelet drugs. The primary outcome is the degree of disability of dependence 2 years after treatment, assessed by the modified Rankin Scale. The secondary outcomes are mRS scores 90 days and 1 year after treatment, recurrence of cerebrovascular events, and severity of neurologic deficit measured using the National Institutes of Health Stroke Scale 1 and 2 years after treatment. The study protocol was approved by the Ethics Committee of Beijing Jishuitan Hospital, China (approval number:201605-01) and conducted in accordance with the guidelines of the Declaration of Helsinki, formulated by the World Medical Association. This trial was registered at ClinicalTrial.gov (NCT02800174). DISCUSSION:Previous studies of the Smart nitinol stent system for the treatment of carotid stenosis are mostly self-control ed case series or smal cohort studies with short fol ow-up periods. Consequently, the long-term influence of Smart nitinol stent deployment on the risk of cerebrovascular events and long-term outcomes are not known. This trial il uminates the therapeutic benefits of the Smart nitinol stent system in a 2-year fol ow-up study involving a large cohort of patients with severe atherosclerotic carotid stenosis.

Objective To summarize the clinical features and vascular lesions in patients who suffered from cerebellar infarction with vertebral artery hypoplasia(VAH). Methods Retrospective analysis was used in the research. The selected patients suffered from cerebellar infarction with VAH or stenosis (stenosis rate≥50%). Seventy-one patients with cerebellar infarction were enrolled. There were 34 patients in VAH group and 37 patients in vertebral artery stenosis group. The age, sex, risk factors, clinical manifestations and characteristics of vascular examination were compared. Results The age, sex, risk factors between two groups had no significant differences (P>0.05). The scores of National Institutes of Health Stroke Scale (NIHSS) between two groups had no significant difference (P>0.05). The proportion of early neurological deterioration in VAH group (41.2%, 14/34) was higher than that in vertebral artery stenosis group (18.9%, 7/37), χ2=4.21, P<0.05. There were more patients with anterior circulation artery stenosis in the VAH group (35.3%, 12/34), compared with that in artery stenosis group (13.5%, 5/37),χ2=4.62, P<0.05. Except the ipsilateral vertebral artery, other arteries stenosis in VAH group (44.1%, 15/34) was significantly higher than that in vertebral artery stenosis group (13.5%, 5/37),χ2=8.20, P<0.05. Conclusions Cerebellar infarction with vertebral artery hypoplasia is more likely to have multiple cerebral arterial stenosis (stenosis rate ≥50%). The patients who suffered from cerebellar infarction with vertebral artery hypoplasia might be prone to early neurological deterioration.

Objective To investigate whether iron mass induces HO-1 overexpression and explore the role of HO-1 in rat intracerebral hemorrhage(ICH). Methods In this study,144 hydrated chloride aldehyde-anesthetized Sprague- Dawley rats were used,autologous blood were injected into the right caudate nucleus to establish the ICH model.Saline injection and health were served as controls.Deferoxamine(DFO)with an intraperitoneal injection served as intervention group.Enhanced Perl's reaction was used for iron staining and brain iron deposits were determined.Brain HO-1 level were examined by immunohistochemical analysis and reverse transcription polymerase chain reaction(RT-PCR). Results There was a 21-fold increase in iron deposits around the hematoma 7 days after the infusion of 100 μl of autologous blood.Markedly increased levels of perihematomal HO-1 immunoreactivity and HO-1 mRNA in all ICH rats were detected at 3-14 days.The addition of DFO significantly reduced iron deposits in the ipsilateral basal ganglia at 7-14 days after ICH.DFO also inhibited HO-1 overexpression at day 7,14.Correlations test showed that there were positive correlations of iron sediments with HO-1mRNA(r=0.647)and HO-1 immunopositive cells(r=0.209). Conclusions ICH causes iron accumulation in the brain.Iron overloading may induce HO-1 upregulation after ICH.Ratherly,the HO-1 moderate increasing possibly fits with the events,whereas HO-1 overexpression may result in its dysfunction.It may be prudent to intervene ICH with HO-1 inhibitor.

Objective:To investigate the effect of methoxyamine combined with target guided fluid in elderly patients undergoing pancreaticoduodenectomy.Methods:90 elderly patients undergoing pancreaticoduodenectomy were randomly divided into methoxyamine group and control group, with 45 cases in each group. The patients in both groups were treated with intravenous inhalation combined anesthesia. The stroke volume variation (SVV) was maintained at 7%-10% and the central venous pressure (CVP) was 4-8 cmH 2O. In methoxyamine group, 3 μg/(kg·min) methoxyamine was continuously pumped, while the control group was pumped with the same amount of normal saline at the same speed. The intraoperative infusion volume, urine volume, bleeding volume, blood transfusion cases, intraoperative mean arterial pressure, heart rate, blood gas analysis results, B-type natriuretic peptide (BNP), creatinine, urea nitrogen level and postoperative exhaust time were compared between the two groups. Results:Compared with the control group, the patients in methoxyamine group had less infusion volume, urine volume, lower postoperative BNP level and heart rate, shorter postoperative exhaust time (all P<0.05), and higher mean arterial pressure ( P<0.05). There was no significant difference in blood loss, blood transfusion cases, PaO 2, PaCO 2, pH, creatinine and urea nitrogen between the two groups (all P>0.05). In addition, the number of patients in the methoxyamine group who used pressor drugs was less than that in the control group ( P<0.05), and the frequency of bradycardia was more than that in the control group ( P<0.05). The proportion of tachycardia and urapidil was similar in the two groups (all P>0.05). Conclusions:Methoxyamine combined with target guided fluid therapy can reduce the intraoperative infusion volume of pancreaticoduodenectomy in elderly patients, stabilize circulation, shorten postoperative exhaust time, and contribute to the recovery of gastrointestinal function.
