Objective To study the expression of MCP-1 in the diabetes mellitus skin defect healing, then discuss its effect. Methods The diabetes mellitus models were established, and the expression of MCP-1 was detected by immunohistochemical staining and Elisa. Results The immunohistochemistry stain showed that the expression of MCP-1 in DM group was higher than that in control group at all time. And the serum value of MCP-1 in DM group had statistical significance ( <0.05) at 3 days or 1 week, but that in 2 weeks and 4 weeks was no statistical significance ( <0.05) . Conclusion The MCP-1 might play a role in the healing of diabetes mellitus skin defect through mediate abnormal inflammatory response.

To investigate the effect of semi-joint prosthesis replacement in treating osteosarcoma around the knee joint,15 children with osteosarcoma around the knee joint underwent semi-joint prostheses replacement and removal of the section with tumor from October 1998 to July 2006.Imageology showed that tumor of 9 children was located at the distal femur,and 6 cases at the proximal tibia.The pathologic changes involved the upper segment of the tibia 9-11 cm in length.All the children had been diagnosed with osteosarcoma by pathological examination,which was graded as stage Ⅱ a according to Enneking staging system.All the patients underwent neoadjuvant chemotherapy preoperatively for 1-2 courses.The size of prosthesis was determined based on preoperative X-ray,CT and MRI.The length of the prosthesis should be 1.0-2.0 cm longer than that of the excised bone.Patellar and collateral ligaments were reconstructed in the artificial semi-knee joint prosthesis.All the 15 patients had a successful semi-joint prosthesis replacement.During the follow-up of 2 to 6 years,body height of the children increases by 4-6 cm,and the affected limbs shortened 1-3 cm.All children could live and study normally.There were 7 excellent,5 good,2 fine and 1 poor according to Enneking evaluation system.The semi-joint prosthesis replacement in the limb salvage surgery for child osteosarcoma around the knee joint can reconstruct knee joint function,remain normal osteoepiphysis,minimize affected limb crispation after operation,and create the condition for total knee replacement in adults.

Objective To study the value of MSCT angiography(MSCTA)in diagnosing lower extremities arterial disease (LEAD) of diabetic foot ulcers and analyze the possible influential factors on the onset of diabetic foot ulcers.Methods 80 diabetic patients for MSCTA examination were divided into two groups by whether combined with foot ulcers.The tibial artery calcification score (TACS) and peripheral arterial occlusion index (PAOI) were calculated and the possible risk factors of diabetic foot ulcer were analyzed.Results There were 30 cases suffered with foot ulcer and 18 cases occurred lower extremity arterial occlusion (LEAO), the average PAOI was 4.40(3.60, 5.75).Non-foot ulcer cases were 50, and there were 8 cases suffered with LEAO, the average PAOI was 2.05(1.43, 3.10).Compared to patients without foot ulcer, patients with foot ulcer were older, had a lower BMI, and were more likely to have a history of tobacco use.They usually had higher TACS and severer peripheral arterial occlusive disease (PAOD).Stepwise regression model showed that foot ulcers had significant correlation with TACS and PAOI.Partial correlation analysis showed TACS was independent from PAOI in impacting diabetic foot ulcer.Conclusion MSCTA has important clinical value in diagnosing and valuing diabetic foot ulcer LEAD.Age, smoking history,BMI,TACS and PAOI affect the incidence of diabetic foot ulcers, and TACS and PAOI are the independent risk factors for diabetic foot ulcers.

AIM: To investigate quantitatively the tubulin expression of basal cells in patients with Alzheimer's disease(AD) and vascular dementia(VD) and evaluate its significance in diagnosing Alzheimer's disease. METHODS: ?-tubulin of basal cells was examined using LSAB immunohistochemical technique, and analyzed qualitatively and quantitatively by image analyzer. RESULTS: The integrated absorbance (I A ,261.43?25.21) and the average absorbance (A A ,1.89?0.14) in the AD group were significantly higher than those (I A ,120.55?19.71 and A A , 0.85?0.14, respectively)in the VD group ( P

ObjectiveTo evaluate temporary balloon occlusion of the abdominal aorta in high-order position sacral tumor surgical operation as a useful adjuvant technique.MethodsReviewed 79 cases of patients from 2005 to 2015 treated in our department and the diagnosis of high-order position sacral tumor. Temporary balloon occlusion of abdominal aorta was used in 50 patients(male 29,female 21)during the sacral tumors surgical operations. The other 29 patients(male 18,female 11)with sacral tumors who received the non-temporary balloon occlusion therapy were used as control group. The statistical differences of the whole surgery time,the blood loss during the surgery,the happening of the postoperative deep vein thrombosis,the time of the postoperative extubation were analyzed. ResultsThe differences were statistically significant(P<0.001)in the whole surgery time of balloon occlusion group(146.36±29.38)min vs non-balloon occlusion group(206.03±125.93)min,the blood loss of balloon occlusion group(1610.70±491.14)ml vs non-balloon occlusion group(2658.62±562.213)mL, and the time of the postoperative extubation of balloon occlusion group(6.60±2.76)d vs non-balloon occlusion group(12.52±2.86)d. However,there was not significant difference of the happening of the postoperative deep vein thrombosis between balloon occlusion group and non- balloon occlusion group. ConclusionTemporary balloon occlusion of abdominal aorta is effective and reliable. It significantly reduced the time of operations,the loss of blood,mean days in hospital,effusion of post-operation and recurrence rate. It makes the operation of sacral tumors much more safer than before and is a technique worthy of popularizing.

Objective To explore the clinical features of transbronchial tuberculous mediastinal lymph-adenitis and value of bronchoscopic interventional therapy. Methods The clinical data of 50 patients who had been diagnosed as tuberculous mediastinal lymphadenitis and had received bronchoscopic interventional therapy in our hospital during the period from January 2008 to January 2013 were retrospectively analyzed. The bronchoscopic change , improvement in symptoms , and time to sputum smear and culture conversion were used to assess the therapeutic effect. The patients were followed up for six months. Results The mean age of the patients was (35 ± 15) years and the male to female ratio was 1:1.2. The lesions occurred mostly at the right middle lobe in 24% (12/50) of the patients. The total effectiveness rate was up to 98% (49/50) after chemotherapy and bronchoscopic interventional therapy. The major complication associated with interventional therapy was hemoptysis (8%, 4/50). After follow-up of 6 months , 49 patients with active lesions were stable , with smooth bronchial mucosa and no obvious obstruction by granulation and caseous necrosis tissues. Conclusions The relavent clinical symptoms of transbronchial tuberculous mediastinal lymphadenitis is mainly caused by tuberculosis inflammation which destroys and blocks the airway. The fiber bronchoscopic therapy with forceps clip and drug infusion has a definite effect and fewer complications.

AIM: To investigate the role of CD134 (OX40) and NF-?B in the pathogenesis of lupus nephritis (LN). METHODS: Renal in situ CD134 and NF-?B expression were examined in 40 biopsy specimens from LN patients by immunohistochemistry and microwave-based immunohistochemistry, respectively. The relationship between expression of CD134 and NF-?B was analyzed. RESULTS: The expression of glomerular and tubular CD134 and NF-?B in LN were higher than that in normal control, especially in class Ⅳ LN, where there was intense staining of endothelial cell, distal tubules, and interstitial mononuclear cell. The CD134 expression of glomerular and tubular was closely related to NF-?B expression, respectively ( r=0.5542,P

Objective To study the influential factors of tacrolimus'dosage and concentration differences between individuals in morning periods after renal transplantation.Methods The clinical data consisted of 118 receptors in morning periods after renal transplantation,whose immune suppressions were tacrolimus,mycophenolate and hormone.At 3,7,14 and 30 d after operation,all the receptors'weight,dosage of tacrolimus,dosage of hormone,diarrhea,blood fat,liver function,renal function,albumn and erythrocrit were recorded respectively,and at the same time their concentrations of tacrolimus and genetic polymorphisms of CYP3A5,MDRl 3435,MDR1 2677 and MDRl 1236 weredetected.Multiple linear regressions were performed.Results The fitting degrees of stepwise regression equations were low.At 3,7,14 and 30 d after operation,the adjusted R2was 0.284,0.267,0.417 and 0.324,respectively.From the aspect of pharmacogenomics,the main factors rela-ted to the differences of tacrolimus'dosage and concentration included MDR1 2677,MDRl 1236 and MDR13435,which varied intensively.Age,albumn,renal function,blood fat and liver function were important factors too.Conclusions The main reasons of the differences of tacrolimus'dosage and concentration between individuals in morning periods after renal transplantation are medicines and changes of internal environment after operation.The genetic polymorphisms of MDR1,age,albumn,renal runetion.blood fat and liver function are important factors too.
