Objective To evaluate the efficacy of endovascular interventional minimally invasive techniques in treatment of acute brachial artery injury.Methods A retrospective case series study was designed to analyzed data of 16 cases (11 males and 5 females) sustaining acute brachial artery injury treated from March 2011 to August 2016.Mean age was 47.9 years (range,27-66 years).Left upper extremity vascular injury occurred in 7 cases and right upper extremity vascular injury occurred in 9.There were 13 cases of arterial intima injury and 3 of arterial pseudoaneurysm.All patients underwent endovascular therapy including stent implantation and balloon dilatation.Angiography was used to evaluate the repair of brachial artery and the operation time was recorded.Improvements of distal limb arterial pulse and limb ischemic symptoms were observed,and the patients who were followed up with stent lumen stenosis more than 50％ received endovascular treatment again.Results The procedures was successful in all patients,with operation time of 30-75 minutes (mean,45 minutes).After the insertion of a stent,recovered brachial artery blood flow and disappeared pseudoaneurysm were observed on angiography,without occurrence of stent stenosis or contrast extravasation.Symptoms of local pain and numbness were alleviated,and blood supply of the distal brachial artery was improved after operation.All patients were followed up for 3-36 months(mean,16.7 months).The false aneurysm did not recur.Two cases of stent stenosis more than 50％ had a second balloon dilation procedure and the blood flow returned to normal.Stent patency was found in 14 cases with stent stenosis of less than 50％.During the follow-up period,no ischemic necrosis,displacement of the stent or stent fracture were found.Conclusion For acute brachial artery injury,endovascular management exhibits higher technical success rate and good clinical outcome with a low incidence of complications.

Objective To observe the effect of community-based rehabilitation stroke unit on the function of stroke patients. Methods 94 patients with stroke were divided into intervention group (n=47) and control group (n=47). The control group accepted routine community home care, while the intervention group accepted community-based rehabilitation stroke unit care. They were assessed with modified Barthel index (MBI), simple Fugl-Meyer assessment (FMA) and Social Disability Screening Schedule (SDSS) before and after intervention. Results There was not significant difference between the groups in scores of MBI, FMA and SDSS (P>0.05) before intervention. All the scores improved significantly in both groups (P<0.01) 3 months after intervention, and improved more in the intervention group than in the control group (P<0.05). Conclusion Community-based rehabilitation stroke unit can improve the functional recovery of stroke patients.

Objective To observe the effect of motor imagery on unilateral spatial neglect (USN) in stroke patients. Methods 40 stroke patients with USN were divided into treatment group (n=20) and control group (n=20). Both groups received routine physical therapy training,while the treatment group received motor imagery in addition. All the patients were assessed with Chinese Behavioral Inattention Test (CBIT), Mini-mental State Examination (MMSE), Fugl-Meyer assessment (FMA) and modified Barthel index (MBI) before and 8 weeks after treatment. Results The scores of CBIT, MMSE, FMA and MBI were better in the treatment group than in the control group (P<0.01).Conclusion Motor imagery combined with routine physical treatment can improve the function of stroke patients with USN and their activities of daily living.

BACKGROUND: Previous studies have demonstrated that acidic fibroblast growth factor (aFGF) combined with partially deproteinized bone (PDPB) (aFGF/PDPB) well promotes avascularization in animals with early-stage avascular necrosis of the femoral head (ANFH), but the histological results remain unknown.OBJECTIVE: To observe the histological repairing effects of aFGF/PDPB on early-stage ANFH in rabbits. METHODS: New Zealand rabbits were established models of bilateral ANFH and were randomly divided into a blank group, a simple PDPB group, and an aFGF/PDPB group. PDPB and aFGF/PDPB bone were implanted into the PDPB and aFGF/PDPB group accordingly. The blank group did not receive any implantation. At 2, 4, and 8 weeks after surgery, all animals were sacrificed for histological examination to observe the osteogenesis by hematoxylin-eosin staining.RESULTS AND CONCLUSION: Defects were filled with granulation tissues and fibrous connective tissues, only a little osteoid tissue formed at the borderline in the blank group at the end of the 8th week. In the PDPB group, a little new bone and cavitas medullaris formed. At 8 weeks, lots of graft was absorbed and cavitas medullaris formed with more osteoplasts and myeloid cells in it. The osteogenesis in the aFGF/PDPB group was better than that of PDPB group in each time point. At 4 weeks, the transplanted cavity was filled with osteoid tissues, a lot of osteogenic precursor cells and osteoblasts could be seen. Plenty of micrangium was observed, and osteoid tissues began to rebuild. At 8 weeks, the graft was replaced by bone tissues, and cavitas medullaris were formed with lots of bone marrow cells in it. At the borderline of the bone trabecula, there were lots of osteoplast and little osteoclasts, which may play a role in bone remodeling. There were mature bone cells in bone lacuna. Results indicate that aFGF/PDPB has better repair effect on rabbit model of ANFH than that of simple PDPB.

Objective To explore the feasibility of local enucleation of pancreatic cystadenoma. Methods From Jan 2001 to Dec 2007, 11 patients with pancreatic cystadenoma underwent operation in Department of General Surgery, first affiliated hospital of China Medical University were enrolled and the clinical features, complications and prognosis were analyzed retrospectively. Results Of the 11 cases, the average age was 47 years old with 2 males and 9 females, the average size of the neoplasm was 4.8cm and 1 located in the pancreatic head, 10 in the body or the tail. Among which 3 cases were serous cystadenoma and 8 were mucinous cystadenoma confirmed by pathological evidence. Three patients developed temporary hyperglycemia and returned to normal after 1~2 weeks; one patient developed incisional infection; two cases developed pancreatic fistula postoperatively. All cases were followed up between 28 and 67 months. No neoplasm re-occurrence or diabetes mellitus occurrence were observed. Conclusions It was safe and feasible to perform enucleation for pancreatic cystadenoma with tumor size less than 6 cm.

Objective To investigate the expression of miR-155 ,nuclear factor kappa B (NF-κB) and soluble intercellular adhesion molecule -1 (sICAM-1 ) in peripheral blood in patients with type 2 diabetes mellitus (T2DM ) ,and to explore the role of miR-155 in vascular lesions of T2DM. Methods A total of 165 T2DM patients and 60 health subjects from health examinations were enrolled in this study. All the subjects were divided into two groups :subjects without vascular lesions group and vascular disease group. Vascular disease group was further divided into microangiopathy group ,macroangiopathy group , microangiopathy+ macroangiopathy group ;based on 24 hUAlb level normal urinary albumin (NAU ) group ,microalbuminuria (MAU) group ,macroalbuminuria (MAAU) group. MiR-155 ,NF-κB and sICAM-1 in peripheral blood were tested by RT-PCR. Single factor analysis of variance was used for comparison among groups. Stepwise regression analysis was used for correlation factors analysis. Results The expression of miR-155 ,NF-κB and sICAM-1 were significantly higher in T2DM group than in NC group [(1.82 ± 0.71) vs (1.00 ± 0.12) ,(2.28 ± 0.66) vs (1.04 ± 0.33) ,(1.88 ± 0.80) vs (1.03 ± 0.30) ,P<0.05]. The level of miR-155 ,NF-κB ,sICAM-1 were significantly higher in T2DM vascular lesions group than in subjects without vascular lesions group [(1.95 ± 0.73) vs (1.34 ± 0.29) ,(2.40 ± 0.65) vs (1.65 ± 0.16 ) ,(2.01 ± 0.77 ) vs (1.07 ± 0.41 ) ,P < 0.05 ]. The expression of miR-155 was higher in microangiopathy+ macroangiopathy group than in macroangiopathy group [(2.36 ± 0.61 ) vs (1.77 ± 0.59) ,P < 0.05 ].The expression of NF-κB was also significantly higher in microangiopathy +macroangiopathy group than in microvascular disease group and macroangiopathy group (P<0.05). The level of miR-155 was significantly higher in group MAU group and MAAU group than in NAU group [(1.41 ± 0.49) ,(2.64 ± 0.52) vs (1.04 ± 0.20) ,P<0.05] ,and NF-κB and sICAM-1 were also higher than NAU group (P<0.05). Multiple stepwise regression analysis showed that miR-155 was positively correlated with NF-κB and sICAM-1(t=4.235 ,9.728 ,P<0.01). Conclusion The expression of miR-155 increases in T2DM patients with vascular complications ,and this trend is the same as NF-κB and sICAM-1. It suggests that miR-155 maybe involves in the pathogenesis of diabetic chronic vascular disease.
