Objective To evaluate CT in the diagnosis of small bowel obstruction in children. Methods Thirty one cases with small bowel obstruction manifestations on CT and plain radiograph were analysed. The age ranged from 9 months to 14 years, male 17 cases, female 14 cases. There were 29 acute small bowel obstructions, and 2 chronic obstruction. Seven cases had history of previous abdominal operation. Results Corred diagnosis was made in 19 cases and 29 cases respectively by plain film and CT. The accurate etiologic diagnosis could be made by CT in 18 cases, including small bowell stone 4 cases, intussusception, 5 localized infection and adhesion 6 intraluminal bowel duplication, 1 congenital umbilical hernia, congenital malrotation of the intestine 1 case.Combined with history of abdominal operation the accurate CT etiologic diagnosis increased to 25 cases.There were 4 CT false negative cases and 2 plain film false negative cases. Conclusion The CT is obviously superior to plain radiograph in detecting strangulation and gas in bowel wall,better dilineating the transitional segment of bowel stenosis thereby demonstrating the case of obstruction which is very helpful for clinical management.

Objective: To compare the curative efficacy and safety of electro-acupuncture on Jianyu (LI 15) with oral administration of Diclofenac Sodium Sustained-release Capsules in treating shoulder periarthritis. Method: Randomized controlled trials (RCT) were adopted in the study. The patients were randomized into two groups, 30 cases in one group.Electroacupuncture was done on Jianyu (LI 15) 20 min every time in the treatment group,while 75 mg Diclofenac Sodium Sustained-release Capsules were orally administered in the control group. For all the patients in two groups, one treatment course contains 7 days. Then the curative efficacy was evaluated by the efficacy evaluation criteria after two consecutive courses. Result: The total effective rate of treatment group and control group were 93.3% and 56.7% respectively. Conclusion: Electroacupuncture on Jianyu (LI 15) is an effective therapy for shoulder periarthritis and has more significant effect than oral Diclofenac Sodium Sustained-release Capsules.

Objective To study whether bellidifolin has rehabilitation effect on injured sciatic nerve rats,and whether ciliary neurotrophic factor (CNTF) is involved in this mechanism.Methods 225 male wistar rats were made to be sciatic nerve injured models,with right sciatic nerve being cut and sewed under microscopy,left sciatic being sham.Rats were randomly divided into control group,bellidifolin 25 mg,50 mg,75 mg groups and mecobalamin group,with 45 rats in each group.Rats in control group were just injected sodium chloride,others were intra-peritonealiy injected different doses of bellidifolin and mecobalamin after operation.Results Three weeks after operation,SFl of control group,mecobalaming group,bellidifolin 25 mg,50 mg and 75 mg group were-84.35± 4.87,-45.20±2.30,-70.42±4.21,-57.73±3.46 and-64.38±4.38 respectively.Compared with control group,others showed significant differences (P＜0.05).There were statistically differences between bellidifolin groups and mecobalaming group(P＜0.05).Within bellidifolin groups,50 mg group showed difference compared with 25 mg and 75 rg groups(P=0.031).TSW results also showed differences among bellidifolin groups,control group and mecobalaming group.There were statistical differences among bellidifolin groups(P＜0.05).Each groups with immunohistochemistry analysis,CNTF expression showed statistically differences among bellidifolin 50 mg group and 25 mg,70 rg groups,Bellidifolin 50 mg group was higher than others(P＜0.05).Conclusion Bellidifolin can promote the recovery of injured sciatic nerve,especially the concentration of 50 mg bellidifolin,and CNTF is involved in the rehablitation process.

Objective To study the rehabilitation effect of Bellidifolin for injuried sciatic nerve,and to explore whether ciliary neurotro-phic factor ( CNTF) is involved in this mechanism. Methods The right sciatic nerver of 225 male wistar rats was cut and sewed under mi-croscopy. Rats were devided into 5 groups,as control group,Bellidifolin 25 mg group,50 mg group、75 mg group and Mecobalamin group. The control group were injected sodium chloride,other groups were injected different dose of Bellidifolin and Mecobalamin. 1,3 and 5 weeks later, the motor nerve conduction velocity( MNVC) and gastrocnemius muscle cross-sectional area were detected,CNTF positive area were analysed by immunohistochemical method. Results There were differences among bellidifolin groups,control group and mecobalamin group in Nerve conduction velocity. Within Bellidifolin groups,50 mg group compared with 25 mg and 75 mg groups,there were statistically differences( P=0. 025). Three weeks after operation,gastrocnemius muscle cross-sectional area of control group,mecobalaming grop and Bellidifolin 25 mg group,50 mg group,and 75 mg group were(455. 06 ± 29. 38),(679. 03 ± 81. 48),(465. 31 ± 71. 55),(670. 24 ± 91. 26) and (669. 28 ± 78. 54) respectively,compared with control group and Bellidifolin 25 mg group,others had a significant difference(P<0. 05). CNTF expres-sion showed billidifolin 50 mg group are higher than others(P<0. 05). Conclusion Bellidifolin can improve the rehabilitation of injured sciatic nerve. CNTF is involved in this mechnism.

Objective To investigate technique of reservation and reconstruction of the extensor mechanism in extraarticular total knee resection.Methods There were 6 cases of fresh total knee joint specimen for anatomical observation.After meglumine diatrizoate was injected into the joint capsule and the deep infrapatellar bursa,the CT examination of the knee specimen was performed.The specimens were detached according to the requirement of extraarticular knee resection,after methylene blue was injected into the joints capsule.The relationships between articular capsule,infrapatellar fat pad and deep infrapatellar bursa were observed,as well as feasibility of extraarticular total knee resection.Four patients with malignant bone tumor around the knee were performed extraarticalar total knee resection.The patellar ligament was reserved completely in 2 patients whose infrapatellar fat pads were not be involved by tumor confirmed by deep infrapatellar bursa radiography.However,the patellar ligament was split along the coronal plane in 2patients who had not undergone deep infrapatellar bursa radiography.The patients were followed up to observe results of tumor control and function of the affected knees.Results Through anatomical observation,some bursas around the knee joints,such as the suprapatellar bursa and popliteal bursa,communicated with the joint cavity,while the deep infrapatellar bursa did not.Furthermore,the infrapatellar fat pad located between the patellar tendon and joint cavity to form a good barrier to tumor invasion.So the patellar tendon could be reserved completely if the infrapatellar fat pad was not involved.Four patients were followed up for 10 to 28 months (average,19 months).At final follow-up,there was no local recurrence and metastasis in all 4 patients.The range of flexion of the affected knees ranged from 95° to 118 ° (average,105 °),and the average extension lag was 22 ° (range,10° to 40 °).The MSTS score was 72.5％.Conclusion For patients with malignant bone tumor involving the knee,the deep infrapatellar bursa radiography should be performed routinely.The patellar ligament could be reserved completely in the extraarticular total knee resection when the deep infrapatellar bursa doesn't communicate with the joint cavity combined with presence of the infrapatellar fat pad.Sometimes,only reserving the superficial half of the patellar ligament also could meet the need of extension.The short-term result of tumor control and function of the affected knee are satisfactory.

Objective To study the clinical and prognostic value of CK19 mRNA-positive circulating tumor cells in early breast cancer patients. Methods We analyzed the peripheral blood in 50 patients with early breast cancer after surgery and before the initiation of any adjuvant treatment for the presence of CK19 mRNA-positive circulating tumor cells using a nest reverse polymerase chain reaction assay. All patients were followed up. Results CK19 mRNA-positive cells were detected in 40.0 %(20/50) of patients with early breast cancer, 12.5 %(3/24) of patients with breast benign lesions, but 5 %(1/20) in healthy individuals (P =0.017,P =0.004); 11 to 20 of them relapsed during the follow-up period (P =0.002). There was no significant association between the detection of CK19 mRNA-positive cell and the patients' menstrual status, tumor stage, tumor size, etc (P ＞0.05). Detection of peripheral-blood CK19 mRNA-positive cells was associated with reduced median relapse-free interval in early breast cancer patients (P =0.007). Conclusion CK19 mRNA is one of the molecular markers for the detection of circulating tumor cells in early breast cancer. Detection of peripheral blood CK19 mRNA-positive cells might be an important predictive value as a marker of relapse in early breast cancer patients.

Objective To retrospectively investigate the endoprosthetic survival and complications after custom-made tumor prosthesis replacement of knee joint.Methods From April 1996 to April 2007,85 patients with bone tumors around knee joints undergoing custom-prosthetic replacement were respectively analyzed,including 54 males and 31 females with an average of 31.33±15.3 years(range,11-72).The diagnoses were osteosarcoma(43 patients),giant cell tumor(31),chondrosarcoma(4),metastatic tumor(3),malignant fibrohistiocytoma(2),Ewing sarcoma(1),and fibrosarcoma(1).The distal femar was affected in 43 patients and the proximal tibia in 42.All patients in this group underwent wide resection and domestic custommade cemented endoprosthetic reconstruction.Results Mean following was 45.8 months.The overall complication rate was 27.1%(23/85),which was 25.6% in distal femar and 28.6% in proximal tibia.Thirteen complications occurred within 3 years after definite surgery,3 in 3-5 years,and 7 over 5 years.All of 6 operation-relation complications(wound dehiscence,periprosthetic infection,peroneal nerve injury,etc) occurred within 3 years.Seven prosthetic-related complications(prosthetic loosening or breaking,dislocation,periprosthetic fracture,etc)occurred within 3 years,3 occurred in 3-5 years,and 7 over 5 years after definite surgery.The overall endoprosthetic cumulative survival rate was 79.4%,67.7%and 62.3% after 3,5 and 7 years,respectively;which was 86.6%,79.2% and 73.5% in distal femur;66.1%,53.7% and 48.8% in proximal tibia.Conclusion All operation-related complications occurred within 3 years,prosthesis-related complications occurred mainly within 3 years and over 5 years postoperatively.Prosthesis-related complications could occur iu the early stage after using domestic custom-made prosthesis reconstruction.

Objective To investigate the spinal stability reconstruction and related complications after total spondylectomy for thoracolumbar tumors. Methods From January 1997 to December 2009, 34 cases with thoracolumbar tumors treated with total spondylectomy, including 20 males and 14 females with an average age of 43 years. The tumors were located in thoracic vertebra in 27 cases and lumbar vertebra in 7, including 6 spinal metastases and 28 primary tumors. The total spondylectomy was piecemeal in 23 cases and en bloc in 11. The reconstruction methods included posterior short-segment fixation in 19 cases, multi-segmental fixation in 13, anterior intervertebral fixation in 2, titanium mesh with auto-bone graft in 20 cases, titanium mesh with bone cement in 7, bone cement filling in 2, auto-bone strut graft in 2, titanium mesh with strengthened rings in 1, artificial vertebral body replacement in 2, posterior massive bone bridging graft in 8 and bone particles graft in 26. Results The mean follow-up time was 43 months. Seven patients died, 5 suffered recurrence. Poor grafted bone fusion was found in 5 cases. The intervertebral sagittal Cobb angle of adjacent vertebra was ??after operation, 9.3?at the end of follow-up or before revision operation. The average lost angle was 14.1?for cases with multi-segmental fixation, and 21.5?with short-segment fixation. Complications included internal fixation broken (5) and loosening (2), titanium mesh subsidence (6) and displacement (3). There were 5 revision surgeries. Conclusion There are relative more complications about spinal stability reconstruction after total spondylectomy. To achieve temporary stiff fixation and long-term fusion, the posterior multi-segment fixation and massive bone bridging graft combined with the anterior artificial vertebral body replacement are effective.

Objective To compare the oxygen saturation between the blood of superior vena cava and mixed venous in lung transplantation and provide reference for monitoring method in anesthesia. Methods 30 patients who received lung transplantation were placed central venous catheter into superior vena cava and flotation catheter into the pulmonary artery in turn. The blood samples were collected from the superior vena cava and pulmonary artery for blood gas analysis simultaneously at the time of just followed the catheter placement (T1), before the resection of the first bad lung (T2), after the reperfusion of the first donor lung (T3), before the resection of the second bad lung (T4), after the reperfusion of the second donor lung (T5), before the end of the operation (T6). The oxygen saturation were compared between the blood of the superior vena cava and mixed venous. Results From T1 to T6, Bland-Altman analysis showed that the mean of deviation between the SpO2 measured in blood of superior vena cava and mixed venous were 0.5, 3.4, 2.3, 0.5, 0.27,-2.9, respectively, and the incidence beyond the upper and lowed limits of consistency zone was 3.3%, 0%, 0%, 3.3%, 3.3%, 0%respectively. The incidence of SpO2 within the consistent limits was 96.7%, 100%, 100%, 96.7%, 96.7%, 100% respectively. Conclusions The SpO2 of superior vena cava may be approximately reference as SpO2 of mixed venous during lung transplantation.
