Objective To explore the effect of osteopontin(OPN) as marker in colon cancer tissue and analyze the relationship between osteopontin and recurrence.Methods ELISA method was used to determine the serum levels of osteopontin in 58 patients with colon cancer(observation group) and 22 cases of normal subjects(control group);semi-quantity RT-PCR was used to detect the expression of osteopontin in tissues.The expression level of OPN mRNA in colon cancer tissue and serum OPN level in 23 recurrence cases and 35 non-recurrence cases one year after operation were observed.Results The OPN mRNA expression in colon cancer tissue and the serum osteopontin level in patients in observation group were higher than those in control group(P

Background and purpose:To investigate the clinico- pathological characteristics, prognosis and diagnosis of primary renal sarcoma that is a rare, highly malignant tumor with poor prognosis and survival. Methods:9 cases of renal sarcoma in our hospital were reviewed and analyzed. Nephrectomy was the main treatment for the patients. All the specimens were stained with histochemicial and immunohistochemical method, correlated literatures were also reviewed.Results:The distributions of pathology were malignant fibrous histiocytoma leiomyosarcoma, liposarcoma, myxosarcoma synoviosarcoma. Immunohistiochemical test was essential for the diagnosis of renal sarcoma.Conclusions:Pain and palpable mass were the common symptoms. Early radical surgery remains the optimal treatment, the role of chemotherapy and radiotherapy in the treatment modalities of the disease is still controversial.

Background and purpose:Fatty acid synthase(FAS)is a new tumor marker,the high expression of which has been reported to be associated with poor prognosis of cancer patients.This study investigated the expression of FAS in transitional cell carcinoma(TCC) of bladder and its clinical significance.Methods:The expressions of FAS were detected by streptavidin-peroxidase immunohistochemical method in the paraffin embedded sections of 65 TCC patients and the clinical data had been reviewed.15 normal bladder tissues were used as control group.Results:The positive rate of the expression of FAS in TCC was 58.5%(38/65),while only 2 of 15 cases in control group expressed FAS protein.The difference was statistically significant,the expression of FAS was related to the histological grades and recurrence but not different pathological stages.Survival analysis revealed that the 5-yr survival rate was lower in FAS positive patients than in negative patients(18% vs.44%,P

Objective To analyze the significance of global end-diastolic volume index (GEDVI) in acute kidney injury (AKI) after septic shock.Methods A retrospective analysis of 61 patients was performed.The patients were diagnosed of septic shock in emergency ward of Shenyang Military Hospital from 2012 March to 2013 May and were monitored by pulse indicator continuous cardiac output (PiCCO).The patients were divided into two groups:low GEDVI group (GEDVI ＜ 700 ml/m2,29 cases) and high GEDVI group (GEDVI≥700 ml/m2,32 cases) by evaluating GEDVI of 24 hour after PiCCO.Several physiologic and biochemical indexes were recorded,including the hemodynamic parameters at the beginning and the 24 h of PiCCO monitoring,Scr,BUN,lactic acid,incidence and mortality of AKI,baseline glomerular filtration rate,baseline Scr,APACHE Ⅱ scores,mortality during the period of emergency ward or within 28 d after the diagnosis.Results A total of 26 cases in high GEDVI group (81.3％) were attacked with AKI,while 16 cases in low GEDVI group (55.2％) were attacked with AKI,the incidence of AKI in high GEDVI group was significantly higher than that in the low GEDVI group.A COX regression analysis of mortality was performed between the patients staying at emergency ward and during 28 d after diagnosis.The results indicated that AKI and GEDVI had no relation with patients' death.Therefore,AKI and GEDVI could not be considered as the risk factors for the prognosis.Conclusions High GEDVI can significantly increase the incidence of AKI after septic shock,therefore high GEDVI should be avoided as much as possible in the course of clinical treatment.

Objective　To study the radiographic findings in the diagnosis of pulmonary lymphoma and pseudolymphoma. Methods　Eight patients with pulmonary lymphoma and 2 with pseudolymphoma were examined by X-ray film, tomography, and CT. Results　Single or multiple nodules or masses were observed in 8 patients with pulmonary lymphoma, shaggy borders or halo of ground-glass attenuation in 7 patients, 2 patients had multiple patchy infiltrates bilaterally, 2 had diffuse interstitial infiltrates and 1 had miliary nodules. Multiple consolidations with air bronchogram and without hilar and mediastinal lymphadenopathy were observed in 2 patients with pulmonary pseudolymphoma. Conclusion　Radiographic findings of pulmonary lymphoma were varied, the most common findings were the nodules or masses with shaggy borders or halo of ground-glass attenuation. The specific findings of pulmonary pseudolymphoma were multiple consolidations with air bronchogram and without hilar and mediastinal lymphadenopathy. The final diagnosis relied on pathology.

Objective To investigate the changing patterns of Staphylococcus aureus (SA) and its resistance from a paediatric clinic in Beijing Children's Hospital Affiliated to Capital University of Medical Sciences.Methods SA isolated from hospitalized patients in Beijing Children's Hospital Affiliated to Capital University of Medical Sciences from Jan.2003 to Dec.2012 were analyzed.Antimierobial susceptibility was determined by disk diffusion method and Phoenix 100 microbiological system.Results were analyzed according to the 2012 guidelines of Clinical and Laboratory Standard Institute.WHONET 5.6 software was used to analyze the data.Results The clinical isolates of SA from inpatient were 2 843.The positive rates of SA were 10.0％,8.7％,9.0％,11.6％,12.7％,11.7％,10.5％,10.8％,11.9％ and 11.7％ form 2003 to 2012,respectively.The positive rate of Methicillin-resistant Staphylococcus aureus (MRSA) from inpatients was 10.9％.The positive rates of MRSA were 3.1％,5.4％,6.4％,4.1％,6.0％,10.6％,11.2％,12.7％,14.1％ aid 20.1％ form 2003 to 2012,respectively.The resistant rate of Methicillin-susceptible Staphylococcus aueus and MRSA to Penicillin were 91.4％ and 100.0％,Oxacillin were 0 and 100.0％,Cefuroxime were 0.5％ and 87.7％,Ceftriaxone were 0.1％ and 90.3％,Amoxicillin-clavulanic acid were 0.9％ and 86.7％,Erythromycin were 72.4％ and 92.2％,Clindamycin were 50.6％ and 80.3％,Ciprofloxacin were 2.2％ and 30.1％,Trimethoprim-sulfamthhoxazol were 12.2％ and 13.9％.Vancomycin-intermediate and Vancormycin-resistant Staphylococcus aureus were not found.Conclusions The prevalence of MRSA is increasing in paediatric inpatients.And MRSA isolates exhibit multidrug resistance.The sequential surveillance about SA is very important for guiding rational antimicrobial therapy and effective control of infections in paediatric patients.

Objectives To analyze the main pathogen of otitis media and antibiotics resistance of clinical bacterial isolates in pediatric patients. Methods Secretion specimens from 164 cases of otitis media were cultured. Antimicrobial susceptibility was determined. Results were analyzed according to the guidelines of Clinical and Laboratory Standard In-stitute (2012). WHONET 5.6 software was used to analyse the data. Results Pathogens were cultivated in 121 ear secretion specimens from 164 cases of otitis media and the positive rate was 73.8%. There were 9 cases of mixed bacterial infection, accounting for 5.5%. 130 strains of pathogens were isolated from middle ear secretion and the main pathogens were bacteria (83.1%) and fungus (16.9%). Among bacteria, 50 (46.3%) were Streptococcus pneumoniae and 21 (19.4%) Staphylococcus aureus. Among fungus, 17 (77.3%) were Candida spp and 5 (22.7%) Aspergillus spp. By age, the rates of infection caused by Streptococcus pneumoniae in infancy and early childhood were markedly higher than those in preschool and school-age, respectively (P<0.05). The no-susceptibility rate of Streptococcus pneumoniae to penicillin was 76.0%. The prevalence of meticillin-resistant Staphylococcus aureus (MRSA) was 14.3%. Conclusions Proper treatment depends on the secretion culture and drug sensitive test due to various pathogens of otitis media.

0.05). Conclusion:There is bigger difference process of tumor apoptosis between different cell types in the same topography site. Survivin may play adjuvant roles and Bcl-2 may play main roles in the inhibition of cell apoptosis in SCLC while the case is just reversed in NSCLC,it suggests that there were different apoptosis inducing factor and different apoptosis pathway due to different cell type in NSCLC and SCLC.
