Objective Study the expressions of intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1) in rat models of cerebral ischemia reperfusion and the protective effect of ?-Sodium Aescinate.Methods Rat models of cerebral ischemia-reperfusion were made using an intraluminal monofilament method and ?-Sodium Aescinate was given peritoneally to observe its protective effect. The histochemical change and the expression of ICAM-1, VCAM-1 were detected by HE staining and immunohistochemistry ways.Results (1) ?-Sodium Aescinate could obviously reduce the brain damage after ischemia reperfusion. (2) The expressions of ICAM-1, VCAM-1 in endothelial cells in ischemic territory increased after cerebral ischemia reperfusion. ICAM-1 immunoreactivity peaked at 24 h after reperfusion and VCAM-1 immunoreactivity peaked at 24～48 h after reperfusion. Both of them decreased gradually, but remained a higher level than normal 72 h after reperfusion. (3) ?-Sodium Aescinate could decrease the expressions of ICAM-1, VCAM-1 remarkably 24 h and 48 h after reperfusion.Conclusions High expressions of ICAM-1, VCAM-1 may be involved in the mechanism of cerebral ischemia reperfusion injury. ?-Sodium Aescinate may play its protective role by reducing the expressions of ICAM-1 and VCAM-1.

Objective:To evaluate the effectiveness and safety of anticoagulant therapy with rivaroxaban in atrial fibrillation( AF) pa-tients after radiofrequency catheter ablation( RFCA) . Methods:A retrospective analysis was performed in the study. Totally 141 AF pa-tients with RFCA in our hospital were enrolled from January 2014 to October 2015. The patients were divided into rivaroxaban group(70 patients)and warfarin group (71 patients). In rivaroxaban group,rivaroxaban(10 mg, po,qd)was given for at least 3 months after RFCA. In warfarin group,low molecular heparin (100 IU·kg-1,ih) was given before RFCA, and standard dose of warfarin (3-5 mg,po,qd) was given for at least 3 months by adjusting the INR within the range of 2. 0-3. 0 after RFCA as bridging therapy. The death rate, throm-boem bolism events and bleeding events between the groups were evaluated and companed groups. Results: There were no significant differences in baseline characteristics between the groups except the diastolic pressure. There were no significant differences in the death and thromboembolism events(transient cerebral ischemia , ischemic encephalopathy, 2/70 vs 4/71,P>0. 05)between the groups. There were no TIMI major bleeding events in both groups. There were no significant differences in minor bleeding events between the groups (3/70 vs 4/71,P>0. 05). Conclusion: Compared with those of warfarin,the effectiveness and safety of rivaroxaban show the similar effect in AF patients after RFCA. Rivaroxaban can be safely and effectively used in AF patients with low or middle risk of thromboembo-lism after RFCA.

Objective:To evaluate the curative effect and safety of fasudil hydrochloride injection in the prevention and treatment of aneurysm postoperative cerebral vasospasm by meta-analysis. Methods: The randomized controlled trials were retrieved from PubMed, EMBASE, Cochrane Library, VIP, Wangfang, CNKI and so on. Meta-analysis was conducted using RevMan 5. 0 software. Results:Totally 418 reference studies were screened, from which 11 ones were chosen including 786 patients in all. In the treatment of cerebral vasospasm (CVS), there was no significant difference between the groups (OR=1. 56, 95%CI:0. 95-2. 58, P>0. 05). While in the prevention of CVS, the incidence rate of CVS in fasudil group was significantly lower than that in nimodipine group ( OR=0. 43, 95%CI:0. 23-0. 81, P=0. 008). However, the incidence rate of ADR in fasudile group was higher than that in nimodipine group (OR=0. 43, 95%CI:0. 25-0. 75,P=0. 003). Conclusion:In the prevention of CVS, fasudil may be better than nimodipine, while the incidence of ADR is higher.

Objective To investigate the angiographic manifestations of renal artery injury caused by percutaneous nephrolithotomy, and to evaluate the therapeutic effect of super-selective renal arterial embolization in treating renal artery injury. Methods A total of 22 patients with persistent or intermittent gross hematuria that occurred after percutaneous nephrolithotomy, who were encountered at authors’ hospital during the period from Jan. 2010 to June 2014, were included in this study. The diagnosis was confirmed by renal angiography in all patients, and super-selective renal arterial embolization with steel micro-coils was carried out in all patients. The patients were followed up for three months. The results were analyzed. Results Of the 22 patients, DSA examination showed that renal artery pseudoaneurysm (RAP) was found in 14 (63.6%), renal arteriovenous fistula (RAVF) in 5 (22.7%) and RAP associated with RAVF in 3 (13.6%). Renal angiography performed after super-selective renal arterial embolization showed that complete obstruction of the bleeding arteries was achieved in all patients, and the active bleeding stopped. Both the technical success rate and the hemostasis rate were 100%. During the follow-up period lasting for three months, no recurrence of hematuria or severe complications occurred. In 20 patients, different degree of embolism syndrome was observed after the treatment. Conclusion Renal artery pseudoaneurysm and renal arteriovenous fistula are the main types of renal artery injury after percutaneous nephrolithotomy. Super-selective renal arterial embolization with micro-coils can be used as the treatment of choice for patients who has failed to respond to conservative therapy.

OBJECTIVE:To compare the efficacy and safety of dabigatran and warfarin respectively used in atrial fibrillation patients after radiofrequency ablation(RFCA). METHODS:Data of 141 nonvalvular atrial fibrillation patients,who scheduled for RFCA,were retrospectively analyzed and divided into warfarin group(71 cases)and dabigatran group(70 cases)by different med-ication. Patients in warfarin group should stop warfarin if they took before,then changed to Low molecular weight heparin calcium injection 100 U/kg,subcutaneous injection,taking RFCA when INR was lower than 1.5,stopping low molecular weight heparin 12 h before surgery;Low molecular weight heparin calcium injection 100 U/kg was intravenously injected when surgery;orally tak-ing Warfarin sodium tablet 4.5 mg after 4-6 h,once a day,meanwhile bridged overlapping treated at least 3-5 d with low molecu-lar weight heparin;monitoring once INR every 3 d after surgery,maintaining INR 2.0-3.0,taking warfalin at least 3 months. Pa-tients in dabigatran group stopped taking the anticoagulant drugs when admission,then changed to Dabigatran etexilate capsule 110 mg(age≥70 years old or body mass<60 kg)or 150 mg(age<70 years old or body mass≥60 mg),twice a day;stopping dabig-atran 24 h before surgery,the same medication as warfalin group when surgery;orally taking dabigatran after 6 h,taking at least 3 months. The total mortality rate,incidence of stroke(transient cerebral ischemia,ischemic encephalopathy),peripheral thrombosis rate and incidence of bleeding after 1 and 3 month(s)in 2 groups were observed. RESULTS:There were no significant differences in the total mortality rate,incidence of stroke,peripheral thrombosis rate and incidence of bleeding after 1 and 3 month(s) in 2 groups(P>0.05). CONCLUSIONS:Dabigatran has similar anticoagulant efficacy and safety with warfarin in atrial fibrillation pa-tients after RFCA.

BACKGROUND: Intrapulmonary vascular abnormalities result in the right-to-left shunting and severe hypoxemia in liver transplantation candidates. Currently, a convenient, sensitive and effective method is absent to screen the intrapulmonary vascular dilatations.OBJECTIVE: To evaluate the role of contrast-enhanced echocardiography on clinical diagnosis of intrapulmonary shunting in liver transplantation candidates.DESIGN, TIME AND SETTING: The experiment, prospective controlled observation based on cases, was performed at the Hepatology Unit of the 458 Hospital of PLA (Guangzhou, Guangdong, China) from February 2004 to February 2006.PARTICIPANTS: Twenty-four consecutive liver transplantation candidates were recruited from the Hepatology Unit of the 458Hospital of PLA.METHODS: Routine examination was conducted under the condition without any regimen of vascular dilatation drugs.Contrast-enhanced echocardiography was applied to detect the prevalence of right-to-left shunting in the patients with end-stage liver disease. The microvesicle of the left ventricle in patients was qualitatively assessed by a score from 1+ to 3+. Accordingly, all patients were divided into two groups: intrapulmonary shunting and non-intrapulmonary shunting.MAIN OUTCOME MEASURES: The prevalence of right-to-left shunting and clinical characteristics of liver transplantation candidates were determined.RESULTS: Ten (41.7%) of 24 patients with positive contrast-enhanced echocardiography were proved to develop the intrapulmonary right-to-left shunting, including 6 for l+ and 4 for 2+ by left ventricle abnormality, which emerged after 6-10 cardiac cycles of right ventricle abnormality. There were no significant differences in age, gender, arterial blood gas analysis and liver function tests between the two groups (P > 0.05). Echocardiography results demonstrated that, the upper digestive tract hemorrhage,spleen thickness that indicated portal hypertension, pulmonary artery systolic pressure and Tei index were significandy higher in the patients of intrapulmonary shunting than in those of non-intrapulmonary shunting (P<0.05-0.01 ).CONCLUSION: Intrapulmonary vascular dilatation occurs frequently in liver transplantation candidates associated with intrapulmonary shunting but without hypoxemia. Contrast-enhanced echocardiography is a sensitive and non-invasive method for the early diagnosis of intrapulmonary vascular dilatation. The pathogenic cause is portal hypertension. Tel index can be used as an important parameter for evaluating right ventricular function in patients of intrapulmonary vascular dilatation.

Objective To evaluate the effects of electromagnetic irradiation of 2000 μW/cm2 exposure on mRNA and protein expression levels of immunoreactive protein and mRNA of NMDAR1 in rats hippocampal,and to explore the impaired mechanism of electromagnetic irradiation on learning and memory.Methods Rats were randomly divided into normal control group, sham-radiated group, and 1 h/d, 2 h/d, and 3 h/d radiation groups.The rats in the radiation groups were fixed and recieved microwave exposure of 2000 μW/cm2, then their learning and memory abilities were tested by Morris water maze experiment, the change of NR1 protein in hippocampal neurons of each group of rats was measured with immunohistochmistry and western blot techniques, and the expression of NR1 mRNA in hippocampus was determined by RT-PCR.Results In the water maze test,compared with the normal control group (8.8 ± 1.66 ), the escape latency of three radiated groups rats ( 1 h/d ( 12.29 ±1.36) s,2 h/d ( 17.99 ±2.25) s,and 3 h/d (24.66 ±5.56) s) were significantly longer (P＜0.05).In the radiation group,the hippocampal neurons of rats showed evident reduction in the ratio of NR1 positive cells,irregular,and arrayed in disorder.Moreover,compared with the normal control group ( (0.70 ±0.11 ), (0.68 ±0.11 ) ) ,the expession of NR1 protein ( 1 h/d (0.122 ±0.026) ,2 h/d (0.102 ±0.023) ,and 3 h/d (0.060 ± 0.009) ) and its mRNA ( 1 h/d (0.46 ±0.07) ,2 h/d (0.35 ±0.05) ,and 3 h/d (0.12 ±0.02) ) in hippocampal neurons was significantly decreased (P＜0.05).Among the indicators, there was no significant difference between sham-radiated group and normal control group.Conclusions Electromagnetic irradiation of 2000 μW/cm2 exposure can impair the learning and memory abilities of rats possibly through a mechanism correlated with the lower expression of NR1 protein and its mRNA in hippocampus.

Objective To investigate the changes and significances of inducible IL-35-producing regulatory T cells(iTR35) in immunological pathogcnesis of Kawasaki disease (KD).Methods Forty-eight children with KD and 32 age-matched healthy children (healthy control group) consented to participate in this study.Flow cytometry was performed to evaluate the proportions of CD4+ FOXP3-IL-12p35+IL-27EBI3+iTR35 and CD4+CD25high FOXP3+regulatory T cells (Treg),and expression levels of associated molecules such as programmed death-ligand 1 (PD-L1),CD169,programmed death 1 (PD-1),CD43,IL-12p35,Epstein-Barr virus induced 3 (IL-27EBI3),glycoprotein 130(gp130),IL-12 receptor beta 2 (IL-12Rβ2),phosphated signal transducer and activator of transcription 1 (pSTAT1) and phosphated signal transducer and activator of transcription 4 (pSTAT4).Transcription levels of the Sre homology 2 domain-containing protein tyrosine phosphatase 2 (SHP-2),phosphatase and tensin homolog (PTEN),Vavl guanine nucleotide exchange factor(Vav) in CD4+T cells were determined by quantitative real-time PCR.Plasma concentrations of IL-35,IL-10,TNF-α and IL-12 were measured by enzyme-linked immunosorbent assay.Results (1) The proportions of iTR35 and its expressions of IL-12p35 and IL-27EBI3 in patients with acute KD dccreased remarkably[iTR35:(0.72±0.26) ‰ vs (1.65±0.43) ‰,P＜0.05],and restored after treatment [iTR35:(1.58±0.63) ‰ vs (0.72±0.26) ‰,P＜0.05].(2) The proportions of Treg and transcriptional levels of IL-12p35 and IL-27EBI3 were down-regulated during acute phase of KD [Treg:(3.26±1.21) ％ vs (7.26±2.86) ％,P＜0.05],and increased to some extent after therapy [Treg:(5.89±2.60)％ vs (3.26±1.21)％,P＜0.05].Meanwhile,plasma concentrations of IL-35 and IL-10,and expressions of gp130,IL-12Rβ2,pSTAT1 and pSTAT4 in iTR35 of patients with acute KD were found lower than those of the healthy control group (all P＜0.05),and increased after treatment (P＜0.05).Additionally,positive correlations were found between plasma concentrations of IL-35 and the proportion of iTR35 or its expressions of IL-12p35 and IL-27EBI3,respectively.(3) Expressions of PD-L1 and CD169 on CD14 + cells and plasma concentrations of TNF-α and IL-12 were elevated significantly during acute KD(all P＜0.05),as well as expression levels of the ligands (PD-1 and CD43) and its downstream molecules (SHP-2,PTEN,Vav) in CD4 + T cells were found to be lower in patients with acute KD (P＜0.05),and restored remarkably after therapy.Conclusion Insufficiency of iTR35 and its expression of IL-35 might be one of the important factors contributing to immunological dysfunction in KD.
