AIM:To study the effect of CD73 on breast cancer cell line MB-MDA-231 adhesion to extracellular matrix.METHODS: ① CD73 siRNA plasmid was constructed and transfected into MB-MDA-231 cells by lipofectamine 2000.② The transfection efficiency was analyzed by flow cytometry using eGFP as a marker gene.Stable transfected MB-MDA-231 cells were selected using G418.③ RT-PCR and Western blotting analysis of CD73 expression in MB-MDA-231 cells was performed.④ The effects of CD73 on MB-MDA-231 cells adhesion to extracellular matrix were assessed by cell adhesion assay.RESULTS: ① Transfection of MB-MDA-231 cells with CD73 siRNA plasmid significantly inhibited CD73 expression at mRNA level.The efficiency was up to 91%.② Transfection of MB-MDA-231 cells with CD73 siRNA plasmid significantly inhibited CD73 expression at a protein level.The efficiency was up to 79.3%.③ Treatment of MB-MDA-231 cells with CD73 siRNA resulted in diminished adhesion to extracellular matrix.CONCLUSION: This study demonstrates that CD73 siRNA effectively inhibits CD73 gene expression in MB-MDA-231 cells leading to adhesion to extracellular matrix suppression.

Objective This study was to investigate the role of lactoferrin and C-reactive protein (CRP)assay in ascitic fluid for diagnosis of spontaneous bacterial peritonitis (SBP)in the patients with decompensated liver cirrhosis.Methods Ascites was collected from the inpatients with decompensated liver cirrhosis before and after treatment from May to December 2011 for anal-ysis of polymorphonuclear cells (PMN)and bacterial culture.The level of lactoferrin and C-reactive protein in the ascites were determined.Results A total of 117 ascites samples were collected from 66 patients.Twenty-six patients met the criteria of SBP with PMN ≥ 250×106/L in ascites,were assigned to SBP group.Of these patients,11 presented with fever 37.3℃ to 38℃, and 11 patients had elevated peripheral blood white cell count > 10 × 109/L.Eleven patients had neutrophil cell percentage >0.75.Only 8 patients in this group had positive bacterial culture.Another 12 patients met the criteria of suspected SBP,and assigned to suspected SBP group.The remaining 28 patients did not satisfy the criteria of SBP,and assigned to non-SBP group.The pretreatment lactoferrin level was (768.46 ± 611 .70)ng/mL and (98.28 ± 56.81 )ng/mL in SBP and non-SBP group,respectively.The pretreatment CRP level was (9.397 ±3.737 )mg/L and (1 .786 ±0.52 )mg/L in SBP and non-SBP group,respectively.The lactoferrin and CRP levels decreased sharply after antibacterial and support-ive treatment in SBP group,which were 657.05 ng/mL and 8.13 mg/L,respectively.The cut-off value of lactoferrin for diagnosis of SBP was 233 ng/mL with sensitivity 96.2% and spe-cificity 97.5%.The cut-off value of CRP for diagnosis of SBP was 4.390 mg/L with sensitivity 92.3% and specificity 92.5%. However,lactoferrin combined with CRP had a sensitivity of 99.70% and specificity of 90.18% for diagnosis of SBP.Conclu-sions Lactoferrin and CRP levels in the ascites of patients with liver cirrhosis are useful for diagnosis of SBP with high specifici-ty and sensitivity.

Objective To investigate the efficacy and safety of perioperative use of different hemostatic drugs in elderly patients undergoing transurethral resection of the prostate (TURP).Methods A total of 480 elderly patients with benign prostatic hyperplasia (BPH) admitted to the Departments of Urology and Gerontology of our hospital from January 2010 to October 2014 were selected and randomly divided into 6 groups (n =80,each).Patients in all groups were given preoperative oral finasteride for 1 week,with each of the non-control groups receiving perioperative heamocoagulase agkistrodon,mangabeys hemocoagulase,reptilase,ethylenediamine diaceturate,or dicynone + paraaminomethyl benzoic acid (PAMBA).Intraoperative bleeding,perioperative hematocrit,hemoglobin change,continuous bladder irrigation time,adverse reactions and other clinical parameters were recorded.Results Operations went smoothly with all patients.Changes in perioperative blood routine indexes,coagulation function,intraoperative bleeding volume and continuous bladder irrigation time had significant differences between the control group and the groups treated with hemostatic drugs (all P＜0.05).No significant differences in perioperative blood routine indexes,coagulation function,intraoperative bleeding volume and continuous bladder irrigation time were found between groups treated with heamocoagulase agkistrodon,mangabeys hemocoagulase and reptilase,or between groups treated with ethylenediamine diaceturate and dicynone+PAMBA (all P＞ 0.05).There were significant differences in the perioperative blood routine indexes,coagulation function,intraoperative bleeding volume and continuous bladder irrigation time between the groups with and without blood coagulation enzymes (all P ＜0.05).Fibrinolytic responses occurred in 2 patients in the heamocoagulase agkistrodon group and were mitigated after drug withdrawal and fibrinogen infusion.Conclusions A reasonable perioperative dose of a hemostatic drug has good clinical effects in elderly patients undergoing TURP.Hemostatic drugs such as blood coagulation enzymes have certain advantages including safety over other types of hemostatic drugs,but their doses should not be too large.

Objective To explore the effect of posterior internal fixation surgery with pedicle screw/rod instrument system in the treatment of thoracic vertebrae fracture-dislocation complicated with a severe thoracic injury. Methods In the 8 cases examined, the range of injury was from T5 to T9, including 1 case of compression fracture-dislocation and 7 cases of burst fracture-dislocation according to Hanley and Eskey’ s classification. According to Frankle’ s classification, 4 were grade A, 3 were grade B, 1 was grade C. All cases were complicated with multiple fractures of bilateral ribs, pulmonary contusion and haemothorax. After the pathogenic condition being stable, reduction and internal fixation were performed with the posterior surgery pedicle screw/rod instrument system. In 5 cases, spinal canal anterolateral decompression was performed homeochronously. The intervals between accidents and operation were 3 to 9 days. Results Operations were performed safely in all patients. The reposition of the alignment and height of vertebraes was good. Postoperative CT scanning showed: in 2 cases, bone block occupied about 10% volume of vertebral canal, and 1 was 50%. The follow-up were 4～36 months, averaging 15 months. No postreduction disposition, internal fixation loosening or breakage occurred. The Frankel’ s classification of neurological function was improved by 1 grade on average. Conclusions After a positive treatment of thoracic injury, it is safe and feasible to treat the fresh thoracic vertebrae fracture-dislocation with the posterior surgery pedicle screw/rod instrument system, and the curative effects are satisfied.

Objective To investigate the relationship between the endoscopic characteristics of chronic gastritis,duodenitis,peptic ulcer and their histopathologic findings in children,and explore the relationship between Helicobacter pylori(Hp) infection and the severity of histopathologic changes of gastroduodenal mucosa in children. Methods Three hundreds and sixty-six children with chronic upper gastrointestinal symptoms who were examined by gastroscopy were enrolled.The gastric and duodenal mucosal biopsy specimens of all the patients were studied histopathologically. ResultsTypes of chronic gastroduodenal diseases in all these patients were: chronic gastritis(n=206,56.3%),chronic gastritis combined with duodenitis(n=112,30.6%),chronic gastritis combined with peptic ulcer(n=48,13.1%).There was chronic inflammation in gastric mucosa and duodenal bulb mucosa in all the cases examined by histopathologic examination.Hp infection was found in 106 cases(28.96%).The gastric mucosal inflammation was more severe in those with Hp infection than those without(P0.05).The were significant differences in the incidences of inflammation activity,atrophia and nodulus lymphaticus of gastric mucosa between those with Hp infection and those without(P

Objective: To observe the clinical efficacy of combining auricular point sticking and a healthy diet to treat simple obesity in children aged 6-9 years old.Methods: A total of 190 eligible obese kids were divided into an observation group and a control group using the random number table method, with 95 cases in each group. The observation group was intervened by auricular point sticking plus guide on a healthy diet, while the control group was only provided with the guide on a healthy diet. The therapeutic efficacy was observed after intervention for three consecutive months, as well as the changes in body mass (BM), body mass index (BMI), waist circumference (WC), hip circumference (HC), and subcutaneous fat thickness. Results: After the 3-month intervention, the total effective rate was 91.6％ in the observation group, versus 74.7％ in the control group, and the between-group difference was statistically significant (P<0.01); in both groups, the BM, BMI, WC, HC, and subcutaneous fat thickness all decreased significantly (P<0.05), and were lower in the observation group than in the control group, showing statistical significance (P<0.05). Conclusion: Auricular point sticking plus a healthy diet is safe and effective in treating simple obesity in children, producing more significant efficacy than healthy diet intervention alone.
