Objective To analyse the effect of eszopiclone combined with sertraline on serum S100βand clinical efficacy in patients with depression after cerebral infarction.Methods 58 patients who were diagnosed with depression after cerebral infarction were collected.All patients were randomly divided into experimental group and control group,29 cases in each group.Patients in the control group received sertraline treatment, patients in the experimental group were given eszopiclone treatment on the basis of control group, after the treatment, the serum levels of S100β,BDNF and clinical efficacy were detected in all patients.Results After treatment, compared with control group, the serum level of S100βwas lower in the experimental group(P<0.05); the serum level of BDNF was higher in the experimental group(P<0.05); the total efficiency was higher in the experimental group (P<0.05).Conclusion The eszopiclone combined with sertraline can significantly reduce the serum level of S100β,and improve serum level of BDNF in patients with depression after cerebral infarction,improve the therapeutic effect.

Objective To investigate the effect of transfusion of allogeneic apoptotic splenocytes on immunological tolerance to pancreatic islets transplantation in rat. Method Recipient SD rats were rendered diabetic mellitus by a single intraperitoneal injection of streptozotocin (STZ). The apoptosis of donor Wistar rat splenocytes was induced by X-irradiation with electron linear accelerator. Pancreatic islets were isolated by intraductal collagenase P, and were purified by Ficoll-400 discontinuous density gradient after culturing for 1-2 days from donor Wistar rat. The diabetic SD rats were randomly divided into 4 groups, and respectively received infusion of Hanks solution, donor normal splenocytes, donor apoptotic splenocytes, and donor necrotic splenocytes via dorsal veins of penis, and then they received pancreatic islets from the same donor rat underneath their renal subcapsular space 7 days later. Mixed lymphocyte reaction (MLR) was used as immunological parameter of transplantation tolerance besides the observation of blood glucose level and allograft survival time. Islet graft failure was defined as the presence of a plasma glucose concentration of at least 11.0mmol/L on 2 successive days. Results The pre-infusion of donor apoptotic splenocytes significantly prolonged the survival time of allograft as shown by the median survival time (MST) of graft of 31days, and the longest survival time of 42 day, and it apparently decreased the rejection response in recipient SD rat in one-way mixed lymphocyte culture. Conclusion Transfusion of donor apoptotic splenocytes could induce immunological tolerance of allogenic islets transplantation in rat.

Idiopathic thrombocytopenic purpura(ITP) as an autoimmune disease,is the most common clinical hemorrhagic disease.But,its pathogenesis is not completely clear yet.Low platelet count can easily repeate in chronic ITP patients,there are poor efficacy in refractory ITP patients,too.In recent years,a series of important progress on the pathogenesis of ITP had been made.In the humoral mechanism,there were significant progress on the emergence of autoantibodies;the theory on anomaly of the megakaryocyte quantity and quality caused by autoantibody were put forward.In the cellular mechanisms,the theory on reduction in the number of Tr cells,Co-stimulative signal and platelets directly dissolved by cytotoxicity T cells were put forward also.This review will be made to sum up the study progress on the pathogenesis of ITP.

Objective To explore the significance of the changes of serum B cell activating factor(BAFF) in children with idiopathic thrombocytopenic purpura(ITP).Methods The concentrations of BAFF were detected by ELISA in 42 children with ITP(test group) before and after treatment in the Children′s Hospital Affiliated to Chongqing Medical University from Apr.to Nov.2008,the blood platelet count(BPC) was detected also.And 40 children who were operated selectively were selected as control group.The variation of concentrations of BAFF were analyzed among children with ITP before,after treatment and control group.Moreover,the relationship between serum BAFF expression and BPC were analyzed by the Pearson test.Results The concentrations of serum BAFF were higher in children with ITP before treatment compared with that in control group [(0.943 3?0.583 5) ?g?L-1 vs(0.538 9?0.234 7) ?g?L-1,P0.05).There was negative correlation between serum BAFF expression and BPC(r=-0.305,P

Objective To compare the clinical outcomes of arthroscopy versus mini-incision surgery for the treatment of avulsion fracture of the tibial attachment of the posterior cruciate ligament (PCL).Methods From March 2001 to September 2009,84 patients with acute displaced avulsion fracture of the tibial PCL attachment were treated operatively in our department.Thirty-five patients were treated with arthroscopic reduction and suture fixation (Group 1); 49 patients were treated with open reduction through a mini-incision and internal fixation with cannulated screw(s) and washer(s) (Group 2).There were 27 males and 8 females in group 1,with a mean age of 29.6 ± 5.6 years old,and 40 males and 9 females in group 2,with a mean age of 32.2 ± 7.6 years old.Based on the Meyers & Mckeever classification,there were 24 type Ⅱ fractures and 11 type Ⅲ fractures in group 1,and 31 type Ⅱ fractures and 18 type Ⅲ fractures in group 2.The 2 groups were compared in terms of range of motion,posterior drawer test (PDT),Lysholm score,International Knee Documentation Committee (IKDC) grading,and clinical results.Results All the patients obtained an average follow-up of 21.5 months (range,13 to 34 months).Primary union was achieved in all the fractures 3 months postoperatively.There were no significant differences between group 1 and group 2 regarding the PDT negative rate [82.9％ (29/35) versus 91.8％ (45/49)],the Lysholm score (95.1 ± 5.6 versus 96.1 ±4.7),therate ofIKDC grade A [88.6％ (31/35) versus91.8％ (45/49)],or the rate of normal range of motion [94.3％ (33/35) versus 93.9％ (46/49)] (P ＞ 0.05).On average,group 1 used significantly longer operative time (92.4 ± 15.9 minutes) than group 2 (53.8 ± 14.3 minutes).Conclusions Both arthroscopy and mini-incision surgery can achieve satisfactory clinical outcomes in the treatment of PCL tibial avulsion fracture.Although the 2 methods make no significant differences in stability of the knee joint and clinical scores,mini-incision surgery can result in much shorter operative time and thus permit an early postoperative rehabilitation.

Objective To observe the effect of inhaled nitric oxide(INO) on the nitric oxide synthase (NOS) in piglet suffered from severe meconium aspiration syndrome(MAS). Methods Severe MAS model of piglet was reproduced, the oxygenation effect and the activity of pulmonary NOS were measured, hybridization in situ of pulmonary slices was used to show the gene expression of inducible NOS(iNOS). Results INO therapy attenuated respiratory dysfunction in MAS, while discontinuation of INO induced “rebound pulmonary hypertension”. The activity of iNOS in MAS group is higher than that in control group (16.9?3.1) fmol/(mg Pro?min)vs (11.6?2.7) fmol/(mg Pro?min),( P

Objective To describe the arthroscopic reductions and fixation of tibial intercondylar eminence fracture with cannulated screws. Methods During February 2003 to September 2005, 40 patients were treated arthroscopically for fracture of the tibial intercondylar eminence. The average age was 29.5 years (11-58 years), with a mean follow-up time of 20.1 months(6-37 months). Among the 40 patients, there were 4 type Ⅱ fractures (10%), 24 type Ⅲ fractures (60%) and 12 type Ⅳ fractures (30%). The fragments were reduced and fixed with cannulated screws. All-arthroscopic technique was adopted in all cases. The hematoma and the fragment were debrided, and the bony fragment was reduced and temporarily fixed with 2-3 guide wires through the portal superomedial to the patella. Intra-operative X-ray was taken to prove the reduction. One or two cannulated screws were used to fix the fragment as the definite fixation. Results The fracture healed completely in all but 1 patient. Lachman test were negative in all patients postoperatively. The average postoperative KT-1000 manual maximum displacement(MMD) was 0.625 mm(?蛳1-2 mm) and average Lysholm score was 98.3 points(87-100 points). The range of motion was normal in 34 patients. Flexion deficit was found in 5 cases, but within 10?. Knee joint stiffness was found in 1 case with range of extension and flexion 0?-30?-45?. A secondary operation with arthroscopic release was performed. The range of extension and flexion was improved to 0?-10?-80? postoperatively. Mild anterior knee pains were found in 8 patients. For 4 young patients with open epiphysis, the cannulated screws were removed 10-12 weeks post operation. No growth disturbance was detected for these 4 patients at final follow-up. Conclusion Arthroscopic fixation of fracture of the tibial intercondylar eminence with cannulated screw is a simple, safe and effective procedure suitable for both children and adult patients.
