Objective To investigate the effect of membrane-cytoskelet on linker Ezrin in the invasion and migration of human adenocarcinoma cells line AGS. Methods Two small hair RNA targeting Villin2 gene ( Ezrin coding gene) was designed,chemically synthesized and inserted into plasmid pGenesil-shRNA,then transformed into E. coli DH5 ?. The recombinant plasmid was extracted in middle quantity and transfected into AGS cells by LipofectamineTM 2000. Ezrin expression in AGS cells transfected by shRNA recombinant plasmid was measured by RT-PCR and Western blotting. AGS cells were transfected by effective shRNA plasmid and cultured in 1640 media containing G418 ( 800 ?g/ml) . RT-PCR and Western blotting were applied respectively to detect the Ezrin mRNA and protein expression to evaluate the blocking effect of shRNA-Ezrin. Cell migration and invasion was determined by scratch test and Transwell chamber assay. Results Our designed shRNA knocked down 93% Ezrin in AGS cells which had a stable expression of Ezrin small hairpin RNAs. The migrated cells number of Ezrin knocked-down group was 27. 67 ? 4. 50,which was significantly decreased compared with the control group ( 125. 50 ? 8. 33,P

Objective To investigate the clinical significance of ultrasound guided biopsy of peritoneum in diagnosis of unex-plained ascites .Methods A total of 95 patients with unexplained ascites after conventional examination were collected ,then under-went ultrasound inspection which showed thickened peritoneum and the relations to surrounding tissues around the planned perito-neum puncture point ,and conducted the peritoneal biopsy .Results A total of 95 were successfully biopsied with 2 -4 peritoneal tissues .Pathological examination showed that 37 cases (38 .9% ) were diagnosed as peritoneal metastatic carcinoma ,41 cases (43 . 1% ) with peritoneal tuberculosis ,5 cases (5 .2% ) with peritoneal mesothelioma ,1 case (1 .1% ) with eosinophilic granuloma ,4 ca-ses (4 .2% ) with fibrous hyperplasia ,and 7 cases (7 .4% ) with chronic inflammatory cell infiltration .The positive rate of ultra-sound guided peritoneal biopsy was 88 .4% .Conclusion The ultrasound guided biopsy of peritoneum is of clinically great signifi-cance in diagnosis of unexplained ascites .

Objective To compare the safety and clinical efficacy between paclitaxel liposomes and paclitaxel in patients with advanced esophageal cancer .Methods A total of 90 patients with advanced esophageal cancer were enrolled into this study and were randomly divided into paclitaxel liposomes treatment group(treatment group) and paclitaxel treatment group(control group) . The patients of each group were treated with paclitaxel liposomes or paclitaxel 80 mg/m2 intravenously on day 1 and 8 ,and nedapla‐tin 75 mg/m2 intravenously on day 1 ,respectively .After two cycles of chemotherapy ,three weeks per period ,we evaluated the short term efficacy and adverse reactions according to the WHO standard .Results The short term efficacy between control group and treatment group showed no significance statistically (P>0 .05) .However ,the incidence of allergic reactions in the treatment group was significantly lower than control group (P<0 .05) .Conclusion Paclitaxel liposomal or paclitaxel combine with nedaplatin was effective equivalently in the treatment of patients with advanced esophageal cancer .But the allergic reactions of paclitaxel liposomal were lower than paclitaxel .It is worthy of clinical promotion .

Objective To investigate the nutritional status of the pupils with cerebral palsy and the factors related with nutrition. Methods The height and weight of 139 cerebral palsy pupil (6~18 years old) were measured. The rate of stunting, wasting, overweight and obesity were calculated, and compared with the norm, and among the subjects with different cerebral palsy type, grade of Gross Motor Function Classification System (GMFCS), famiy background (urban or rural), age, etc. Results The rate of stunting and wasting was more than the norm, and the obesity was less. The rate of stunting negatively correlated with the grade of GMFCS. The rate of wasting negatively correlated with the age. Conclusion It is important to focus on the physical development delay and malnutrition of children with cerebral palsy.

Objective: To explore deep vein thrombosis (DVT) occurrence in patients after right heart catheterization and the effect of anticoagulant therapy. Methods: A total of 171 consecutive patients with electrophysiological study (EPS) and/or radiofrequency catheter ablation (RFCA) in our hospital from 2015-01 to 2016-05 were enrolled. All patients had supra-ventricular tachycardia and completed a venous surgery, they were randomly divided into 2 groups: Anticoagulation group,n=87 and Non-anticoagulation group,n=84. Lower extremity vascular Doppler ultrasonography was performed at (24-48) h post-operation to compare the incidence of DVT between 2 groups. Results: There were 13/171 patients were excluded for not completing post-operative lower extremity vascular Doppler ultrasonography including 9 patients in Anticoagulation group and 4 in Non-anticoagulation group. 158 patients finished post-operative examination and follow-up study. Anticoagulation group had 7/78 (8.97%) patients suffered from DVT, Non-anticoagulation group had 41/80 (51.3%) patients suffered from DVT,P<0.001. Conclusion: The incidence of DVT was higher after right heart catheterization without anticoagulation; heparin treatment may reduce DVT occurrence in relevant patients.
