Objective To explore the spatio-temporal regularity of cerebral edema in the early stage of severe burn (50% TBSA Grade Ⅲ) with four-dimensional (4D) mathematic model. Methods Twenty-six dogs were randomly divided into control group and 6, 12, 18 and 24 hours post-burn groups. The dogs in the postburn groups suffered severe burn of 50% TBSA GradeⅢ. Six hours after burn, 50 g/L glucose was injected according to Parkland formula. MRI manifestation, histopathological changes, brain water content and intracranial pressure were observed in each group. A 4D mathematic model was established based on the results of MRI scanning. Results Two turning points ( 6 and 18 hours postburn) and three phases of pathologic changes were displayed by 4D mathematic model of cerebral edema in the early stage of severe burn. The first phase (6 hours postburn) was in the subclinical period,when an effective treatment should be taken as quickly as possible so as to prevent deterioration of postburn cerebral edema. The second phase ( 6-18 hours postburn) was in the apostatic period with pathologic characteristic of vasogenic and cytotoxic brain edema. The third stage (18-24 hours postburn) was the critical period of cerebral edema. Intracerebral pressure (ICP) increased rapidly due to limitation of cranial cavity, when cerebral hernia easily happened. Conclusions The 4D model indicates that there is a feature of type S curve in the pathologic process of cerebral edema in the early stage after severe burn.

Objective To discuss the clinical value of subintimal angioplasty (SIA) in treating long segment occlusion of superficial femoral artery (SFA) in the elderly,and to observe the follow-up results.Methods Subintimal angioplasty was performed in 66 elderly patients with stage Ⅱ-Ⅳ long segment occlusion of SFA.The improvement of ankle-brachial index (ABI) and the long-term patency rates were observed and analyzed before and after treatment.Results Of 66 elderly patients,the surgery was successfully performed in 64 cases (97 ％).Skin temperature was improved,the claudication disappeared or a claudication distance was prolonged,the rest pain disappeared or relieved,foot infection was under control and turned into the dry gangrene in these patients.SIA was given up in 1 case because the wire failed to return to the true lumen and the distal outflow segment was occluded.One patient underwent bypass grafting instead of SIA because the wire failed to get into the subintimal.The ABI got obvious improvement before and after treatment (0.59±0.16 vs.0.84± 0.21,P＜0.01).The patency rates in 62 patients undergoing SIA at 6,12,24,36 months were 85.5％ (53/62),69.4％ (43/62),54.8％ (34/62) and 48.4％ (30/62) after surgery,and the 3-years limb salvage rate in 62 cases was 96.6％ (60/62).Conclusions Subintimal angioplasty is an effective method for treating long segment occlusion of superficial femoral in elderly patients,and it has the satisfactory long-term follow-up results.

Objective To evalute effects of low calcium concentration dialysate on blood pressure,ionized calcium and serum endothelin-1 of uremic patient with hypertension during hemodialysis.Methods 60 uremic patients with hypertension during hemodialysis in the Shengjing Hospital of China Medical University were dialysated with different calcium concentration(1.75 mmol/L followed by 1.25 mmol/L).TO measurearterial blood pressure,ionized calcium and serum endothelin-1 before and after each dialysis session.Results The post-dialysis blood pressure,ionized calcium and serum endothelin-1 level of uremic patients using DCa1.75 with hypertension during hemodialysis were increased significantly than those of pre-dialysis and post-dialysis with DCa1.25(P

Induction of immune tolerance is characterized by high efficiency,low toxicity and economic advantages,and immune tolerance has very important significance in organ transplantation.In the establishment of immune tolerance,dendritic cells (DCs) play the key roles such as clonal deletion or clonal anerge,expressing t-cell inhibiting factors,activating helper T cells electively and inducing regulatory T cells,especially CD4 + CD25 + regulatory T cells,etc.Similarly,CD4 + CD25 + regulatory T cells whose primary target point is dendritic cell also have various functions such as affecting dendritic cells'maturing,restraining dendritic cells'antigen presentation to T cells,inhibiting the activation of T cells in non-specific ways and inducing immune tolerance.Current research shows,dendritic cells and CD4 + CD25 + regulatory T cells regard each other as target point and work synergetically.Here we mainly discuss the function and interaction of dendritic cells and CD4 + CD25 + regulatory T cells in the immune tolerance.

Objective To evaluate the role of real-time three-dimensional transesophageal echocardiography(RT3D-TEE) in non-valvular atrial fibrillation with left atrial appendage(LAA) stunning after catheter ablation.Methods Clinical and echocardiographic variables were analyzed by univariate regression in order to investigate the relationship between the group of LAA stunning and others in 28 patients after catheter ablation.Results Univariate analysis revealed difference in persisting time of atrial fibrillation[(16.4 ± 11.6)weeks vs (21.3 ± 18.6) weeks,P ＜0.05],left atrial diameter[(43.4 ± 8.3) mm vs (47.6 ± 5.9) mm,P ＜0.05 ],left atrial emptying fraction (0.38 ± 0.04 vs 0.30 ± 0.09,P ＜0.05).LAA emptying fraction based on three-dimensional volume measurements had significant difference (0.20 ± 0.03 vs 0.12 ± 0.02,P ＜ 0.001) between the group of LAA stunning and other cases.Conclusions LAA ejection fraction calculation by RT3D-TEE is feasible and more accurate than by clinical and other echocardiographic in LAA stunning after ablaton of atrial fibrillation.

Objective:To observe the influence of valsartan combined with Bailing capsules on urinary albumin excretion rate in early stage of type 2 diabetic nephropathy ( DN) , and explore its protection in early DN. Methods:Sixty patients with early DN were randomly divided into two groups. On the basis of diet control and blood glucose regulation, the control group (n=30) was given valsartan 160 mg, qd, while the prevention group (n=30) was treated by valsartan (160 mg·d-1) combined with Bailing capsules (2. 0g, po, tid), and the treatment course was 12 weeks. The urinary albumin excretion rate ( UAER) , mean arterial blood pressure ( MAP) , serum creat-inine ( Scr) and hemoglobin A1c ( HbA1c) were measured and compared before and after the treatment in the two groups. Results:UAER in the two groups was significantly reduced after the treatment compared with that before the treatment (P<0. 01), and that in the prevention group was obviously lower than that in the control group (P<0. 01). MAP in the two groups was significantly decreased after the treatment as well (P<0. 01), while there was no significant difference between the two groups. Scr and Hb Alc in the two groups showed no significant changes before and after the treatment (P>0. 05). Conclusion:Valsartan combined with Bailing capsules shows certain effects in the treatment of early stage of type 2 diabetic nephropathy by decreasing the urinary albumin excretion.

Objective:To assess the ability of axillary reverse mapping (ARM) to identify and preserve the arm lymphatics drainage as well as determine its ability to reduce lymphedema. Methods:A total of 300 breast cancer patients who underwent axillary lymph node dissection (ALND) from June 2009 to May 2011 were enrolled in this study. Methylene blue dye (2 mL to 3 mL) was injected into the ipsilateral upper inner arm along the medial intramuscular groove to map the upper extremity lymphatic drainage system prior to ALND. The blue lymphatic and lymph nodes were identified and preserved during the operation. The change in the arm circumference was the selected method of measurement. The difference in the bilateral upper arm circumference was recorded after 2 months (difference≥2 cm is defined as lymphedema). Results:The ARM was performed successfully in 195 (65%) of 300 patients. The incidence of lymphedema was significantly lower in the successfully mapped patients than in the failing mapping patients, with statistically significant difference during follow-up at 6, 12, 18, and 24 months post operation. Conclusion:The ARM technique can identify and preserve the arm lymphatics drainage and prevent upper extremity lymphedema after breast cancer axillary lymphadenectomy.
