Objective To find the effect of chronic renal failure on the development of neointimal hyperplasia and the role of monocyte chemokine-1 (MCP-1) after arteriovenous fistula in mice.Methods We created AVF (common carotid artery to jugular vein in an end-to-end anastomosis) in mice with or without chronic renal failure (renal ablation or sham operation).The outflow of AVF was harvested at 3 weeks postoperative the vascular tissue.The pathological changes were examined.The level of blood urea nitrogen (BUN) and the degree of intimal hyperplasia were analysed.The protein and mRNA expression of alpha smooth muscle actin (SMA), Ki-67,NF-κB and MCP-1 were detected by immunohistochemistry, RT-PCR and Western blot.Results 1)Compared with the control group, the blood BUN level of the experimental group was significantly higher and the intimal hyperplasia was more serious, meanwhile, the lumen was more narrow (P<0.05).2)In the experimental group, the expression of α-SMA, Ki-67, NF-κB and MCP-1 was significantly increased (P<0.05).3)MCP-1 promoted the proliferation of vascular smooth muscle cells.Conclusions Chronic renal failure promote the development of neointimal hyperplasia, which may be related to the increase of MCP-1 expression.

The diseased location of rectal cancer in China is mainly in the middle and low rectum, and the proportion of young patients is increasing. As the surgical resection of primary tumor is still the cornerstone of rectal cancer treatment, it has become the hotspot in the treatment of low rectal cancer to preserve the anus after radical surgery. This paper reviews the research progress of sphincter-preserving treatment for low rectal cancer.

Objective To investigate the expression of nuclear factor(NF)-?B and intercellular adhesion molecule (ICAM)-1 in rat′s retina injured by ischemia-reperfusion, and the effect of pyrrolidine dithiocarbamate (PDTC) on the expression of NF-?B and ICAM-1. Methods The model of retinal ischemia-reperfusion was set up in 60 SD rats, which were divided into two groups with 30 rats in each: ischemia-reperfusion group and ischemia-reperfussion with injection of PDTC group. The left cephalic artery of each rat was ligated, and the right side was the control. Every group was subdivided into group 1 hour, 6, 12, 24, 48, and 72 hours after ischemia-reperfusion injury, and with 5 rats in each group. mRNA of NF-?B and ICAM-1 mRNA was measured by in situ hybridization (ISH) method in rat′s retina. Every rat underwent electroretinography (ERG) at the corresponding time before executed by neck breaking. Results In ischemia-reperfusion group, expression of NF-?B and ICAM-1 was detected at the 6th hour after ischemia-reperfusion, reached the highest level at the 24th hour, and weakened gradually later. In ischemia-reperfusion with injection of PDTC group, expression of NF-?B and ICAM-1 was detected at the 12th hour after ischemia-reperfusion, and reached the highest level at the 24th hour but lower than that in ischemia-reperfusion group. No expression of NF-?B and ICAM-1 was found in the control group. The relative recovery rate of ERG a and b wave amplitude in ischemia-reperfusion groups was lower than that in ischemia-reperfusion with injection of PDTC group at every stage(P

Objective To investigate the clinical features of patients with neuromyelitisoptica spectrum disorders (NMOSD) in China.Methods Cases reports of NMOSD from 1989 to 2016 were retrieved from the database of Weipu data basis,and the clinical features of cases reported were analyzed.Results Eighty-seven studies were enrolled.Totally 109 patients were included.The ratio of male to female was 1 ∶ 4 and the mean onset age was (38.44 ± 17.08) years (range 5-76 years).The predisposing factors was catching a cold(12.80％).There were 66.05％ patients with optic neuritis symptoms as initial symptoms,23.85％ with spinal cord inflammation as the first symptom.Spinal magnetic resonance showed that 80.73％ of the lesions involved thoracic spinal cord,and the cervical spinal cord occupied by 49.54％,while the lumbar spine accounted for about 10.09％.12.84％ involved the final area.Conclusion In China,NMSOD is common in young adults,and more common in women.The onset age between the male and female has no significant difference.The first symptom of optic neuritis is more common,and the spinal cord lesion in thoracic cord is popular.

ObjectiveTo investigate the role of heme oxygenase-1 (HO-1 ) in process of sevoflurane preconditioning attenuating hypoxia-reoxygenation (H/R) injury in cultured neonatal rat cardiomyocytes.Methods Primary cultured neonatal rat cardiomyocytes were randomly divided into four groups ( n ＝ 25 each):control group (group C),group H/R,sevoflurane preconditioning group(group S + H/R),and HO-1 inhibitor zinc protoporphyria (ZnPP) and sevoflurane preconditioning group(group ZnPP + S + H/R).In group H/R,the cardiomyocytes were exposed to 2 hours of hypoxia,followed by 1 hour of reoxygenation.Group S+ H/R received 2.5％ sevoflurane preconditioning for 20 minutes followed by 10 minutes of wash-out before H/R.ZnPP was added to the culture medium with final concentrations of 3 μMol/L 1 hour before sevoflurane preconditioning and H/R in group ZnPP +S + H/R.HO- 1 expression,apoptosis rate,concentration of free calcium ( [ Ca2 + ] i),mitochondrial membrane permeability transition pore (PTP),cytoohrome C ( Cyto C) expression and activities of lactate dehydrogenase (LDH) and creatine kinase (CK) in culture supernatant were detected after reoxygenation.ResultsCompared with group C,the expression of HO-1 and cytoplasmic Cyto C of cardiomyocytes were up-regulated,mitochondrial Cyto C was down-regulated,while the [Ca2+ ]i,opening degree of PIP,apoptosis rate and activities of LDH and CK in culture supernatant were increased in group H/R.Compared with group H/R,the expression of HO-1 and mitochondrial Cyto C of cardiomyocytes were up-regulated,cytoplasmic Cyto C was down-regulated,while the [Ca2+ ] i,opening degree of PTP,apoptosis rate and activities of LDH and CK in culture supernatant were decreased in group S + H/R.Compared with group S + H/R,the expression of HO-1 and mitochondrial Cyto C of cardiomyocytes were down-regulated,cytoplasmic Cyto C was up-regulated,while the [Ca2+ ]i,opening degree of PTP,apoptosis rate and activities of LDH and CK in culture supematant were increased in group ZnPP + S + H/R.ConclusionThe up-regulation of HO-1 is involved in the process of sevoflurane preconditioning attenuating hypoxia-reoxygenation injury in cultured neonatal rat cardiomyocytes.

Objective To evaluate the effects of inhaled iloprost on pulmonary hypertension after cardiopulmonary bypass in patients with congenital heart disease undergoing surgical correction of anomaly. Methods Fifty-eight patients with congenital heart disease aged 14-60 yr undergoing surgical correction of anomaly under cardiopulmonary bypass (CPB) were enrolled in this study. Radial artery was cannulated before induction of anesthesia. A 6-lumen pulmonary catheter was placed via right internal jugular vein after tracheal intubation. Their mean pulmonary arterial pressure was still > 25 mm Hg after operation. ECG, HR, BP, CO, PAP and SpO_2 were continuously monitored. Aerosolized iloprost 10 fig was inhaled via nebulizer after CPB. Hemodynamics were measured before iloprost inhalation (baseline) and at 0, 5, 15, 30 and 60 min after the end of iloprost inhalation. Results There were 28 patients with pulmonary hypertension after CPB among the 58 patients with congenital heart disease. Inhalation of iloprost 10μg significantly decreased mPAP, pulmonary vascular resistance and intrapulmonary shunt as compared with the baseline. Iloprost inhalation could also improve significantly CO and the mixed venous oxygen saturation (SvO_2 ). Conclusion Iloprost inhaled after CPB can effectively reduce pulmonary arterial pressure and pulmonary vascular resistance in patients with congenital heart disease undergoing surgical correction of anomaly and help them wean from CPB.
