0.05).Furthermore,the mean survival time for renal allograft with CD20 and C4d double-positive was 32.2?12.3 months,and with C4d single-positive it was 81.2?15.6 months.Log-Rank test demonstrated that graft survival in recipients with both CD20 and C4d double-positive expression was significantly lower than that in recipients with C4d single-positive expression(P

Objective To review the strategies for multiple coronary artery bypass in patients with calcified ascending aorta.Methods From June 2002 to December 2007,36 patients with multiple coronary artery disease and calcified ascending aorta underwent OPCAB without aortic side-bite clamping.The patients(28 males and 8 females) aged from 60 to 83 years with a mean of(69.1?6.7) years.Fifteen of the patients had a history of stroke.Coronary angiogram revealed that 3 patients had double vessels disease and the others had triple vessels disease,involving the left main stem in 14 cases.The left ventricular ejection fraction ranged from 0.32-0.69.Calcified ascending aortic plaque can be explored in 30 of the patients during operation while intra-operative transesophageal echocardiography indicated calcified aorta only in 28.No-touch technique was used in 22 patients either with LIMA as the only inflow and the saphenous vein grafts was anastomosed to the LIMA in 15 patients,or with bilateral internal mammary arteries as the only inflows in 7 patients.Proximal anastomotic device was employed in 14 patients to finish the proximal anastomosis of greater saphenous vein grafts without aortic side-biting clamping.Intra-operative graft flow meter was used to check the flow of grafts before chest closure. Results Totally 116 cases of distal anastomosis were performed in the 36 patients(2-5 in each,mean 3.2?0.9).The patients woke up from anesthesia in 2 to 22 hours.Intraoperative measuring of graft flow revealed satisfying blood flow in all the grafts.In the 15 patients with LIMA as the only inflow,the total graft flow in the main stem of LIMA was basically the sum of each connected grafts.Only one patient died after surgery,showing a mortality rate of 2.7%.Eight patients(26.7%) had transient atrial fibrillation after the operation,2 showed pulmonary infection,4 had chest fluid,1 showed infection of the incision at the lower limb.All the complications were cured.30 patients achieved a 6-to 60-month follow-up with a mean of(33.8?11.2) months.During the period,11 patients(37 grafts) were examined by angiography,which showed that all the grafts of LIMA to LAD and vein grafts were patent,except in two vein grafts,which were occluded in the diagnol branches. Conclusions In patients with remarkable ascending aortic calcification,OPCAB combined with aorta no-touch technique or proximal anastomosis device can effectively decrease the incidence of postoperative stroke.

Objective To investigate the effect of medial preoptic area ( mPOA) destruction on the anesthesia induced with propofol and ketamine and the role of mPOA in the mechanism of anesthesia. Methods Twenty-four SD rats weighing 250-300 g were randomly divided into two groups: NS group ( n = 12) and NMDA destruction group ( n = 12) . The animals were anesthetized with intraperitoneal (ip) pentobarbital 40 mg?kg-1. A hole was drilled in the skull fixed by a stereotactic apparatus (Narishige). 0.5?l of normal saline (NS) or N-methyl-D-aspartate (NMDA) was injected into mPOA. The rats were observed for changes in behaviour and body weight. On the 7 th day after NS or NMDA injection each group was further divided into 2 subgroups receiving either propofol 100 mg?kg-1 or ketamine 100 mg?kg-1 ip. The latency of loss of righting reflex (RL)(time from end of ip injection to loss of righting reflex) and recovery time (RT) were recorded. Results There were no significant changes in behaviour and body weight after mPOA injection in NS group; while animals in NMDA-destruction group showed increased excitability , irritability and activity and decreased appetite and sleep and significant weight loss after mPOA injection. RL was significantly longer and RT was significantly shorter after propofol/ketamine ip injection in NMDA destruction group than those in NS group. Conclusion mPOA is probably involved in anesthesia induced with propofol and ketamine.

ObjectiveTo observe the effect of community-based rehabilitation (CBR) on older stroke patients in ability of activities of daily living (ADL).Methods50 older stroke patients were randomly divided into the rehabilitation group and control group. The rehabilitation group was treated with motor function exercise and ADL training, while the control group only took medicine. Two groups were evaluated with Barthel index before and after treatment. ResultsScores of Barthel index on the rehabilitation group were higher than that on the control group after treatment, and there was a significantly difference between two groups (P<0.01). Conclusions CBR has the significant effect on improving ADL in older stroke patients.

·AIM: To investigate whether Erigeron Breviscapus (vant) Hand-Mazz (EBHM) EBHM has neuroprotective effect against N-methyl-D-aspartate (NMDA)-induced neuron death in retinal ganglion cell layer (RGCL).· METHODS: 60 healthy SD rats were randomly divided into four groups. 6 animals were normal control group (group A). The others were divided as group B (EBHM group), group C (normal saline+NMDA group) and group D (EBHM + NMDA group). Each group had 18 rats.10nmol NMDA was intravitreally injected to induce partial damage of the neurons in RGCL in the right eyes of Groups C and D. Same volume PBS was intravitreally injected into the left eyes as self-control. Groups B and D were pre-treated intraperitoneally with 6g/L EBHM solution at a dose of 150mg/kg body weight/day seven days before and after NMDA treatment. Group C were administrated intraperitoneally with 9g/L normal saline at the same time of EBHM injection. Rats were sacrificed at 4,7,14d after NMDA treatment. Flat whole retinas were stained with 5g/L cresyl violet and neuron counting in RGCL from both eyes were observed. Each subgroup had 6 rats.· RESULTS: There was no significant difference of neuron counting in RGCL between the right eye and the left eye in group A (P=0.200). There was no significant difference between normal control group and EBHM group either in the right eyes or in the left eyes at 4, 7 and 14 d respectively after intravitreal injection of 10nmol NMDA in group C and group D. (P=0.636, P=0.193). Neuron counting of RGCL in group C and D was significantly decreased in the NMDA-treated eyes at 4, 7 and 14d after intravitreal injection (P＜0.001). There was no significant difference between self-control eyes group and normai control group(P＞0.05). However, neuron counting was significantly higher in the EBHM+NMDA group than normal saline +NMDA group at 14days after intravitreal injection (P=0.044), but was lowered than normal control group (P＜0.05).· CONCLUSION: EBHM has no effect on neuron counting of RGCL when administered alone in normal rats.The results indicates that EBHM plays a partial protective role in NMDA-induced neuron loss in RGCL in the rats.

Background Medical refraction after cycloplegia is the preferable choice for precise measurement of degree of refractive error.Drugs used in China for cycloplegia include atropine and tropicamide,and the use of cyclopentolate is an alternative for ophthalmologist.However,the data for the evaluation and comparison of efficacy of the available drugs in cycloplegia is still lacking.Objective This system analysis was to evaluate the difference between atropine and cyclopentolate in cycloplegia in children.Methods A systematic literature retrieval was conducted in MEDLINE,EMbase,Google residual accommodation after cycloplegia by atropine and cyclopentolate were compared.Statistical analysis was performed using the RevMan 5.1.0 software.Results A total of 7 studies were included in this meta analysis,including 6 cohort study design and 1 randomized,doubleblinded clinical trial and 1232 eyes.For retinoscopic evaluation after cycloplegia,no significant differences were found between cyclopentolate and atropine in children with hyperopia and myopia (WMD =-0.21,95％ CI:-0.47-0.06,P=0.13 ; WMD =-0.10,95％ CI:-0.36-0.15,P =0.43).For residual accommodation after cycloplegia,no significant difference was seen between cyclopentolate and atropine in ammetropic children (WMD =0.30,95％ CI:-0.10-0.71,P =0.15).Conclusions Cyclopentolate shows the same effect on the cycloplegia as atropine in children,and it can take the place of atropine in cycloplegia in childhood.

Objective To observe insulin resistance in first-degree relatives of patients with Graves disease. Methods All subjects in control group and experiment group including first-degree relatives of GD patients underwent oral glucose tolerance tests (OGTT) and insulin releasing tests then the degree of insulin resistance was analyzed. Results Blood glucose at each point of OGTT, insulin level and insulin resistance index 1 (HOMA-IR) of experiment group were higher than those in control group, while insulin activity index (IAI) and HOMA-βwere significantly lower than those in control group. Conclusion Patients insulin resistance could be found among first-degree relatives of GD patients.
