Objective To investigate the polymorphism of the vitamin D receptor gene (VDR)TaqⅠin relation to diabetic retinopathy. Method Fragment length discrepant allele specific PCR(FLDAS-PCR) were used to determine VDR genetypes in 158 patients with diabetic retinopathy and in 198 normal subjects. Results The frequency distribution of VDR genotypes in diabetic retinopathy patients was 106 (67.1%) in TT, 33(20.9%) in Tt, 19(12.0%) in tt; and in normal persons was 165 (83.3%) in TT, 23(11.6%) in Tt, 10 (5.1%) in tt. There was a significant difference between diabetic retinopathy patients and normal persons in distribution of VDR gene TaqⅠgenotypes(P

A case of a 47-year-old female patient who had a severe headache for 2 days was reported. Spontaneous subarachnoid hemorrhage (SAH, hunt-Hess classification Ⅱ level)-anterior communicating aneurysm rupture was diagnosed by brain CT and digital subtraction angiography (DSA) examination.Intravascular interventional aneurysm embolization was performed, and the patient appeared progressive limb weakness 5 days after operation. Physical examination revealed grade Ⅱ upper limb muscle strength and grade Ⅰ lower limb muscle strength. The muscle tone of the extremities was decreased,and the tendon reflex disappeared. The pinprick pain was decreased below the double wrist joints and the ankle joints. After neuroelectrophysiology test and cerebrospinal fluid assay, the patient was diagnosed as Guillain-Barré syndrome associated with subarachnoid hemorrhagic aneurysm embolization.

Objective To observe the effects of indole-3-carbinol on neointimal hyperplasia and restenosis of rat artery after balloon injury and the possible mechanisms.Methods Balloon dilation was used to establish the neointimal injury model of left carotid artery in rats.Twenty Sprague-Dawley rats were randomly divided into single balloon dilation group(control group)and balloon dilation followed by indole-3-carbinol therapy group(therapeutic group).After balloon dilation,indole-3-carbinol(12.5,25,50 mg/d)was applied to the rats for 7 days respectively.The rats were killed two weeks after balloon dilation and the injured vascular specimens were harvested for pathologic examination and immunohistochemical staining.Results ①The neointimal thickness,neointimal area in the therapeutic groups were significantly less than that of the control group(P

Objective To discuss the surgical characteristics,safety and perioperative management of carotid stent angioplasty (CSA) for the treatment of severe carotid artery stenosis (＞85％).Methods From December 2011 to May 2016,a total of 25 patients with carotid artery stenosis (＞85％) were treated with CSA.According to the stenotic characteristics of the lesion,distal cerebral protection device was employed in performing CSA.During the operation,attention was paid to individualized and detailed surgical management and perioperative management program;the revascularization and the dropping-off of thrombus in cerebral protection device were under close observation,while effort was made to control the occurrence of complications.The patients were followed up for one year to observe the occurrence of ischemic cerebrovascular events.Results The cerebral protection device was successfully deployed after it passed over the severe carotid artery stenosis.After balloon pre-dilation the stent was deployed,and the stent showed satisfactory shape.North America Symptomatic Carotid Endarterectomy Testing (NASCET) showed that the average degree of carotid artery stenosis was decreased from preoperative (91.0±3.1)％ to postoperative (21.0±5.1)％.The protective umbrella was successfully retrieved in all patients,and deciduous tissue fragments were observed in 6 retrieved protective umbrellas.During the perioperative period no severe complications,such as cerebral hemorrhage,cerebral infarction,hyper-perfusion syndrome or death,were observed.All the 25 patients were followed up for one year,and no transient ischemic attack,stroke or death occurred.Conclusion In treating severe carotid artery stenosis with CSA,in order to ensure a successful surgery and patient's safety the following points are very important:in-operative individualized and detailed management,perioperative preventive measures,and use of appropriate cerebral protection device.

ObjectiveTo investigate the role of ischemic postconditioning on lung ischemic/reperfusion injury induced by cardiopulmonary bypass (CPB) in combined mitral and aortic valve replacement,and evaluate the effects of different protocol of ischemic postconditioning,and analyze its possible mechanisms.Methods24 patients diagnosed as rheumatic mitral and aortic valve disease with or without tricuspid valve disease were randomly divided into 3 groups (8 in each):Control group( group A),patients undergoing routine cardiac surgery; Postconditioning group Ⅰ (group B ),patients undergoing routine cardiac surgery and ischemic postconditioning by occlusion of the pulmonary artery of five cycles of 15 s ischemia and 15 s repeffusion before the pulmonary artery totally restoring peffusion; Postconditioning group Ⅱ (group C),patients undergoing routine cardiac surgery and ischemic postconditioning by occlusion of the pulmonary artery of five cycles of 30 s ischemia and 30 s repeffusion before the pulmonary artery totally restoring perfusion.The Oxygenation Index (OI) was measured at pre -operation and 1 h,2 h,3 h,6 h and 12 h after terminating CPB.The plasma contents of MDA were detected by Enzyme-linked Immunosorbent Assay at pre -operation,1 h,3 h,6 h and 12 h after terminating CPB.ResultsCompared with group A and C,OI in group B significantly increased at 1 h,2 h,3 h,6 h after terminating CPB (283.25 ±56.47 vs 384.76 ±29.17 vs 310.50 ±65.71,265.75 ±58.78 vs 381.75 ±29.67 vs 310.50 ±48.17,283.75 ±73.15 vs389.74±39.34 vs 317.87 ±78.41,310.37 ±52.00 vs 401.62 ±4 2.89 vs 337.25 ± 64.06,all P ＜0.05),and the plasma contents of MDA in group B reduced at 1 h,3 h,6 h,12 h after terminating CPB (4.64±0.63 vs 3.88 ±0.20 vs 4.38 ±0.41,5.75±0.49 vs 4.44 ±0.34 vs 5.28 ±0.76,4.42±0.31vs 3.77 ± 0.40 vs 4.35 ± 0.54,3.74 ± 0.31 vs 3.19 ± 0.17 vs 3.64 ± 0.24,all P ＜ 0.05 ), However,there were no significant differences in OI and MDA between group C and A (all P ＞0.05 ).Conclusions Ischemic postconditioning by occlusion of the pulmonary artery of 5 cycles of 15 s ischemia and 15 s reperfusion attenuates lung oxygenation function injury induced by CPB in double valves replacement,and it is possibly mediated by reducing MDA produced by lipid peroxidation.However,ischemic postconditioning by occlusion of the pulmonary artery of 5 cycles of 30 s ischemia and 30 s repeffusion may not have significant protective effect for lung oxygenation function injury induced by CPB in double valves replacement.
