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: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

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.

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.

Currently campus violence including the murder case in which college students shot teachers has shocked the whole society,arousing various issues for educators.This paper holds that the carrying out of life education is one key solution to those new rising social issues.Through discussing the origin of students' ignorance of human lives,the significance and measures of performing life education are explored in this paper.

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.

Objective To examine current use, associated complications, and short-term outcomes in patients with acute myocardial infarction (AMI) requiring intra-aortic balloon pump (IABP) counterpulsation. Methods A single-centre registry was conducted between October 2004 and July 2008. Data were collected from 121 consecutive AMI patients treated with IABP counterpulsation at the 28th Division of Beijing Anzhen Hospital. Results Among 806 patients with AMI, IABP counterpulsation was employed in 121 patients. Placement of an IABP was indicated for hemodynamic support during high-risk catheterization and/or angioplasty (66.9%) and cardiogenic shock (27.3%). Balloon insertions were successful in 98.3% of patients and duration of mean use was 34.2?16.2 hours. No major IABP complications occurred in all the patients. Diagnostic catheterization was performed in all the patients inserted with IABP, and 93.4% underwent coronary revascularization before hospital discharge. The total in-hospital mortality was 13.2% (34.4% in patients with cardiogenic shock) and varied markedly by indication and use of revascularization procedures. Conclusion IABP counterpulsation may be successfully employed for a wide variety of conditions in the AMI setting, providing significant hemodynamic support with rare major complications in a high-risk patient population. IABP counterpulsation may reduce mortality in patients with AMI undergoing reperfusion therapy.

Objective To observe the effect of electroacupuncture(EA) on the expression of glucose transporter-1(GLUT-1) of hippocampal microvascular endothelial cells in focal cerebral ischemia(CI) rats.Methods Sixty male Wistar rats were randomly divided into sham-operation,model and electroacupuncture(EA) groups.CI model was established by middle cerebral artery occlusion with a piece of thread embolus.EA(4 Hz/20 Hz,1 mA) was applied to bilateral "Neiguan"(PC 6) for 30 min,once daily for 15 days.GLUT-1 expression in the hippocampus was detected with immunohistochemistry and Western blot,respectively.Results After the treatment,compared with the sham-operation group,the expression of GLUT-1 in microvascular endothelial cells of the hippocampus in model group shown by both histochemical and Western blot techniques decreased apparently(P

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.

OBJECTIVE:To approach the correlations of carbamazepine concentration in serum with clinical therapeutic effect,dosage,sex,age and body weight in epileptic children.METHODS:158 monitoring records for serum concentration of carbamazepine in children with epilepsy in our clinical pharmacy department were consulted retrospectively.Data such as serum concentration,sex and age were recorded into data base and were analyzed using SPSS 13.0 software.RESULTS:No significant correlation was noted between serum concentration of carbamazepine in epileptic children and sex.However,serum concentration of carbamazepine was closely correlated with clinical therapeutic effect,dosage,age and body weight.CONCLUSION:The individual difference in the metabolic processes of carbamazepine was concerned with age and body weight,so it's necessary to make individualized regime according to child's specific condition and monitoring results.
