Objective To study the relation between chronic stressful, the neural changes in prefrontal cortex and depression. Methods Adapt chronic unpredictable stress with separate model to make depression model rats. After 22 days all the rats were killed and use immunohistochemistry method and computer image analysis to detect BDNF. To analysis the date with SPSS11.5 software. Results After 21 days stress, body weight ( t =2.915, P < 0.05), ambulation ( t = 6. 245, P < 0. 01 ), rearing( t = 2.693, P < 0. 05 ) and grooming ( t = 2. 685, P<0.05) decreased and stopping time in center( t=2. 388, P<0. 05) ,defecation( t =3. 846, P<0. 01 ) increased in experimental group. BDNF expressed obviously in control group and the prefrontal cortex expressed highly than that of the experimental group. BDNF expressions of experimental group were lower than that in control group ( P< 0.01 ) especially in right prefrontal cortex. Conclusion There was no difference of BDNF distribution in prefrontal cortex between both groups ,but after 21 days stress ,the BDNF levels of experimental rats obviously descent,especially in right prefrontal cortex.

Objective To evaluate the clinical effect of the enteral nutrient(Pediasure) on making improvements in nutritional status of children with anorexia.Methods Thirty children were treated with pediasure for 2 months, twice a day, and height(Ht),weight(Wt),AG,TSF,SSF,ASF,RBC,Hb were measured before and after treatment and their appetites,alimentary canal reactions were recorded.Results Compared with the effects after 2 months, the average Ht,Wt,AG,SF all increased, and there was significant difference between pretreatment and after treatment(P0.05). All of the 30 children had no adverse reactions during treatment.Twenty-two children (73.33%) had better appetites and increased the amount of eating after treatment.Conclusion The study suggests that pediasure may be safely used in the treatment of children′s anorexia and effectively improve patients′ nutrition without adverse reactions.

Objective To discuss the advance and experience of postoperative management in multivisceral transplantation(MVT).Methods Five patients with abdominal multiple organs malig- nances were subjected to multivisceral transplantation.The excised specimens included the liver,pan- creas,duodenum,stomach,spleen,mesentery and all of the involved lymph nodes.The transplanted organs were liver,pancreas,duodenum and parts of intestine.Patients were monitored and sustained stably in breath,hemodynamics and homoeostasis.The coagulation was also monitored and kept in balance.The intensive immunosuppressive protocol,including steroid,tacrolimus,mycophenolate mofetil and Zenapax,was used to prevent the acute rejection.The endocrine and exocrine of pancreas were tested,color Doppler examination was done every day,and Somatostatin was used to prevent pancreatitis.Drugs to bacteria,fungus and virus infection were prophylactically used.Results All patients waked up with 4-6 h after operation and began recovering with 3-7 days.Dynamic examina- tions revealed that the functions of grafted liver,pancreas and duodenum were satisfactory.No com- plications of acute rejection,pancreatitis,bleeding and thrombosis occurred.Conclusion Many ques- tions in postoperative management related to multivisceral transplantation are devoted to study.Nice experience of management to organ transplantation,detailed monitoring and prophylactically medica- tions are safeguards to steady recovering and further prognosis.

Objective To investigate the relativity of the lupus anticoagulant(LAC), anticadiolipin antibody(aCL) - IgG,aCL-IgM,aCL-IgA levels and clinical symptoms of systemic lupus erythematosus (SLE), and to determine the significance of the LAC level in the prognosis of idiopathic thrombocytopenic purpura (ITP) by detecting the LAC and aCL-IgG, IgM,IgA levels in 310 children with SLE and 249 children with ITP. Methods Kadin-cephalin clotting time(KCCT) and correcting test to detect the plasma LAC level and to the serum aCL- IgG, IgM, IgA levels with enzyme - linked immunosorbent assay. Results In SLE group, there were 66.1% patients with higher LAC among whom 45.9% patients suffered from lupus nephritis , aCL subantibody level elevated in 46.8% patients (90.2% IgG and/or IgM) serum; 46.9% and 11.7% patients suffered from central nervous system diseases and blood diseases with SLE respectively. In ITP group, 36.2% patients with LAC positive were diagnosed as SLE by detecting the serum antinuclear antibody level, and 7.6% suffered from SLE subsequently in the period of 2 months to 2.4 years. Conclusions The LAC and aCL subantibody levels may have an important relativity with the clinical symptoms of SLE. The LAC is the predominant pathologic autoantibody in patients with lupus nephritis, and the aCL subantibody( IgM, IgG) levels were related to lupus thromboangiitis. The IAC level of children with ITP should be monitored in order to determine the prognosis of the disease as soon as possible.

[Objective]To explore the roles of TIDC(tumor infiltrating dendritic cell)and TIL-T(tumor infiltrating T lymphocyte)in tumor immunity of EBV-associated gastric carcinoma(EBVaGC)and their clinical significance.[Methods]TIDC and TIL-T in EBVaGC(n=49)and EBVnGC(EBV-negative gastric carcinoma)(n=20)were detected by immunohistochemistry method and then their subtypes and their relationships with clinical and pathological factors were analyzed.[Results]Mild infiltration was detected in 29 of 49(59.2%)EBVaGCs and 18 of 20(90%)EBVnGCs,while marked infiltration of TIDC was detected in 20 of 49(40.8%)EBVaGCs and 2 of 20(10%)EBVnGCs.And the difference between the two groups was significant (P=0.013).The number of TIL-T in EBVaGC was hisher than that in EBVnGC(P=0.017),and most of them were CTLs.The number of TIL-T was positively correlated with that of TIDC(r=0.386,n=49,P=0.006).The degree of TIL-T infiltration in EBVaGC had negative relationship with the lymph node metastasis(P<0.001),while TIDC had no relationship with the clinical features.[Conclusion]TIDC and TIL-T may play important roles in the tumor immunity of EBVaGC;TIDC may contribute to the TIL-T recruitment in EBVaGC.

Objective To investigate and analyze the postoperative progression of ossification of the patients with ossification of the posterior longitudinal ligament (OPLL) on cervical spine. Methods From Jaunary 2001 to December 2007, 95 postoperative patients with cervical OPLL were followed and analyzed retrospectively. There are 72 males, 23 females, with the average age of 56.3 years (range, 40-73years). The follow-up time was from 1 to 6 years, average 3.1 years. Among them 36 patients were performed with anterior cervical corpectomy, fusion with titanium mesh and fixed with cervical plates, others treated with posterior cervical laminectomy and fixation. 2 of the 95 cases were performed anterior and posterior combined operation. Clinical data, X-rays, CT and MR images and progression of ossification, were measured and analyzed in details .The relationships between the progression of ossification and relative factors, as gender, age, C3 ossified involved, T-OPLL, OPLL-type, time of follow-up, surgical approach, Japanese Orthopaedic Association (JOA) scores and improvement rate of JOA scores, were analyzed. Results Progression of ossification in 39 cases among the 95 followed postoperative OPLL patients, 28 men and 11 women, average age 55.9 years, range 41-71 years. The age of progressed patients included 12 cases of ≤49 years, 12of 50-59 years, 12 of 60-69 years and 3 of ≥70 years. 35 patients were operated by posterior approach and only 4 treated with anterior operation. According to the standard of the progression of ossification that 2 mm in the length or/and thickness, there are 4 cases progressed only in length, 2 only in thickness, other 33 patients both the length and thickness. Progression of length is from 2mm to 20mm (average 7.74±4.71). But thickness is progressed from 2 mm to 6 mm (average 2.67±1.51). From 1 to 3 years follow-up time it appeard as a downtrend about the progression of ossification. But it may appear an uptrend from the 4th year. JOA score and improvement rate of the JOA score were almost improved to the high-point in three years. And according to the statistic data there are obvious relationship between progression of ossification with age, surgical approach and C3 ossified involved. Conclusion There is a high rate of postoperative ossification progression in cervical OPLL patients. Cervical OPLL patients with C3 ossification involved, performed with posterior laminectomy and those young at surgery may have higher rate of progression of the ossification. The JOA score and improvement rate of the JOA score were little influenced by the progression of the OPLL during the short and intermediate-term follow-up.
