BACKGROUND: Based on previous studies, the combination of basic fibroblast growth factor (bFGF) with graft may accelerate the procedure of vascular invasion of anterior cruciate ligament (ACL) graft. The antigenicity of graft could be inhibited by the destruction of major histolocompatibility complex (MHC) through the treatment of allogenous tendon by freeze. The freeze. dried tendon showed advantages including prolonged storage time. availability for transport and possibility of commercial application. There is no experimental and clinical study on the graft substance of bFGF combined tendon in ACL reconstruction in animal model so far. OBJECTIVE: To observe histologically the effect of exogenous application or bFGF combined to freeze-dried tendon on angiogenic enhancement in early ACL reconstruction. DESIGN, TIME AND SETTING: Controlled animal study, which was performed in the Department of Orthopeadics, Xijing Hospital. Fourth Military Medical University of Chinese PLA between June 2006 and June 2007.MATERIALS: Fourteen dogs were used in the experiment. METHODS: Extensor digitorum longus tendon was harvested from the rest 2 dogs and treated by freeze-dry as graft for other experimental dogs. bFGF(100 u g/L)was combined to freeze-dried tendon and then transplanted into one side knee to substitute the original ACL. While only freeze-dried tendon was used in the transplantation at the other side as control. MAIN OUTCOME MEASURES: Twelve of them were randomly divided into 6 groups according to the 6 time points,i,e.,1,2,3,4,5,6 weeks after surgery(2 dogs in each group).The histological observation with HE staining was done under microscope to mainly observe the angiogenesis in the transplanted ACL. RESULTS: Neovascularization occurred at the 2nd to 3rd weeks and reached the peak at the 4th to 5th weeks postoperatively at the experimental sides. By contrast. The neovascularization occurred at the 4th to 5th weeks postoperatively at the control sides. Neovascularization in the combined group was longer and deeper than that in the control group. CONCLUSION: The time of neovascular formation and the depth of vascular penetration into the tendon in the group of bFGF combined to freeze-dried tendon are superior to those in the control group.

Objectives The study aims were to analyze the clinical features and to explore the management of intrapancreatic pseudocysts after acute pancreatitis.Methods A retrospective study was conducted on 151 patients who received surgical treatment from Dec,2008 to Feb,2012 after acute pancreatitis.Based on CT/MRI findings and clinical data,there were 17 patients with intrapancreatic pseudocysts (11.3％).The clinical manifestations,diagnoses and treatments for these 17 patients were retrospectively analyzed,and the outcome after operations were followed.Results For the 17 patients,obstructive jaundice was present in 3 patients,pancreatic portal hypertension (PPH) in 7,pseudoaneurysm in 2.All 17 patients underwent operation.The surgical procedures included internal drainage (n=8),external drainage (n=5),distal pancreatic resection with splenectomy (n=3),and local resection (n=1).All patients recovered after the operations.Conclusions Intrapancreatic pseudocysts after acute pancreatitis had a high incidence of local complication.The diagnosis of these pseudocysts was difficult.The treatment should be performed early for those patients who had developed complications.

Objective To investigate the effects of rapamycin which is an autophagy inducer and 3-adenine (3-MA) which is an autophagy inhibitor on motor behavior and autophagy related protein LC3 in C57BL/6 mice of Parkinson's disease(PD).Methods 40 C57BL/6 male mice were randomly divided into control group and experimental groups which consist of MPTP model group,rapamycin group and 3-MA group,with 10 in each group.Mice in experimental groups received intraperitoneal injection with MPTP to establish PD models,and mice in control group received intraperitoneal injection with the same amount of saline solution for 1 week.Mice in rapamycin group received intraperitoneal injection with rapamycin and mice in 3-MA group received intraperitoneal injection with 3-MA at the same time when MPTP was injected.Animal behavior detections were carried out on the 1 th,7th and 14th day after the last injection.After the last injection,mice were sacrificed and sections of midbrain nigra were gained for the detection of expression of autophagy specificity protein LC3 by Western Blot.Results Compared with MPTP model group,rapamycin could improve the general condition and behavioral manifestation of mice in pole test((14.89± 1.14) s vs (16.24±1.39) s,P＜0.05;(15.18±1.36) s vs(17.93±1.11s),P＜0.01),traction test((1.7±0.5) vs (1.2±0.4),P＜ 0.05;(1.5±0.5)vs (1.1±0.3),P＜0.05) and open field test which contained total activity distance((5 875.3 ± 1148.9) cm vs (5 061.5±773.1) cm,P＜0.05;(5 753.2± 1 106.7) cm vs (4 669.3±969.1) cm,P＜0.01) and average speed((19.29±2.35) cm/s vs (16.47±3.01) cm/s,P＜0.05;(18.71±2.71)cm/s vs (15.80±2.50) cm/s,P＜0.01),while 3-MA aggravated behavioral deficits of mice in pole test(19.92± 1.61s vs 17.93± 1.11 s,P＜0.05),and both total activity distance((3 879.7±575.0) cm vs (4 669.3±969.1) cm,P＜0.05) and average speed((13.34± 1.87) cm/s vs (15.80±2.50) cm/s,P＜0.05) in open field test were decreased.The results of Western Blot confirmed that rapamycin could increase the expression of LC3-Ⅱ,however 3-MA could re duce the expression of LC3-Ⅱ.Conclusion This study confirmed that rapamycin could alleviate behavioral symptoms of PD model mice and increase the level of LC3 in midbrain nigra,while 3-MA could exacerbate behavioral symptoms in PD model mice and decrease the level of LC3 in midbrain nigra.Thus it can be speculated that drugs which can regulate autophagy may be potential treatment protocols for PD.
