Objective To survey membrane inhibitor of reactive lysis(MIRL) expression in non-small cell lung careinoma(NSCLC) and to analyze the relationship between MIRL expression and clinical staging, adjuvant chemotherapy and disease-free survial. Methods The expression of MIRL in 8 adjacent tissues and 36 NSCLC sam-pies were determined by immunohistochemistry. Furthermore, the relationship between MIRL expression and clinical stage ,adjuvant chemotherapy and disease-free survival was assayed by follow-up. Results Among 36 samples of non-small-cell lung cancer,there were 10(27.8%) samples expressing MIRE. Out of 18 samples of squamous carcinoma, 4(22.2%) expressed MIRL,while 6(37.5%) expressed it in 16 samples of adenocarcinoma,there was no statistical significance between them(P>0.05). There were no expression in 2 samples of large cell carcinoma. There was no correlation between MIRL expression and disease-free survival(P>0.05). MIRL positive expression rate in patients with preoperational adjuvant chemotherapy was significantly lower than that of those without preoperational adjuvant chemotherapy(P<0.05). Conclusions There is great percentage of MIRE expression in NSCLC. Our present study suggests that the immunological inhibition of MIRL should be blocked when monoclonal antibody is used in the treat-merit of NSCLC.

The study aims to investigate the effect of the ratio of long axis to short axis (RLS) of upright polypropylene infusion bag on discharging process and to search the best RLS. Aiming at five different RLS (1. 5 : 1, 2 : 1, 3 : 1, 4 : 1 and 5 : 1, respectively) with the volume of 100 mL, 250 mL and 500 mL, respectively, based on finite element method, analyzing the variation of stress distribution, emptying rate, drugging space and steadiness coefficient, etc. For the bags of the same volume, emptying rate increased with increasing of RLS, but the steadiness coefficient decreased with increasing of RLS. The specific increasing amplitude of emptying rate and decreasing range of steadiness coefficient were as follows: 20% and 49% for 100 mL infusion bag, 9% and 51% for 250 mL infusion bag, and 11% and 46% for 500 mL infusion bag, respectibvely, when RLS increased from 1. 5 : 1 to 5 : 1. Comparatively speaking, the increasing amplitude of the emptying rate is remarkably less than the decreasing range of the steadiness coefficient. By comprehensive consideration of both emptying rate and steadiness coefficient, lower RLS is recommended for upright polypropylene infusion bag.

Objective Lung cancer has been the most common cause of cancer death worldwide.More than three quarters is diagnosed at advanced stage.Nearly one half has distant metastases outside the chest cavity.It has been recognized that oligometastatic state exists in natural history of malignant tumors,which has significantly better prognosis than those with polymetastases.The eighth edition of TNM staging system defined NSCLC with a single metastasis as a new separated stage(M1 b).Long-term survival of oligometastatic NSCLC patients treated with local control methods has been reported in literatures.But whether surgical resection of liver metastasis has benefit or not remains unknown.We performed a systematic review of surgical therapy for NSCLC with limited liver metastases.

Objective To investigate the effect of sufentanil postconditioning on myocardial ischemiareperfusion (I/R) injury in patients undergoing cardiac valve replacement under cardiopulmonary bypass (CPB).Methods Sixty ASA Ⅱ or Ⅲ patients ( NYHA Ⅱ or Ⅲ ) of both sexes,aged 19-64 yr,scheduled for cardiac valve rreplacement under CPB,were randomly divided into 4 groups ( n =15 each):control group ( group C),sufentanil 0.5 μg/kg group (group S1 ),sufentanil 1.0 μg/kg group (group S2 ) and sufentanil 2.0 μg/kg group ( group S3 ).In groups S1,S2 and S3,sufentanil 0.5,1.0 and 2.0 μg/kg were infused over 2 min via aortic root 5 min before aortic unclamping respectively.In group C,the equal volume of normal saline (2 ml/kg) was infused instead of sufentanil.Blood samples were taken from the radial artery immediately before induction of anesthesia ( T2 ) and at 2,4,8,24 and 48 h after aortic unclamping ( T1-5 ) for determination of plasma concentrations of cardiac troponin-I (cTnI) and malondialdehyde (MDA) and activities of creatine kinase isoenzyme-MB (CK-MB) and superoxide dismutase (SOD).The duration of CPB,time of aortic clamping,extubation time,duration of stay in ICU,and myocardial contractility score and volume of drainage at 24 h after the operation were recorded.The restoration of spontaneous heart beat and adverse cardiovascular events were observed.Results The plasma cTnI,and MDA concentrations and CK-MB activity were significantly lower,while the SOD activity was significantly higher at T1-3 in group S1 than in group C ( P ＜ 0.05).The plasma cTnl concentration and CK-MB activity were significantly lower at T1-5,the plasma MDA concentration was significantly lower at T1-4,and SOD activity was significantly higher at T1-4,the extubation time and duration of stay in ICU were significantly shorter,and the myocardial contractility score at 24 h after the operation and incidence of adverse cardiovascular events were significantly lower in groups S2,3 than in group C ( P ＜ 0.05),The plasma cTnl concentration and CK-MB activity were significantly lower at T4,5,The plasma MDA concentration was significantly lower at T4,the SOD activity was significantly higher at T3,4,and the myocardial contractility score at 24 h after the operation was significantly lower in groups S2,3 than in group S1 ( P ＜ 0.05).Conclusion Sufentanil postconditioning can relieve myocardial I/R injury in patients undergoing cardiac valve replacement under CPB,and the mechanism is related to inhibition of lipid peroxidation.

Objective To analyze copy number variance (CNV) in whole genome by using gene chip technology, and to screen the radiosensitivity associated genes on esophageal squamous cell carcinoma (ESCC). Methods The patients with ESCC who received radiotherapy alone in Anyang Tumor Hospital from December 2013 to August 2016 were selected, and biopsy paraffin samples were preserved in the center of pathology. The patients were divided into radiosensitivity group (group S) and radio-resistance group (group R). DNA was extracted from these paraffin samples in both groups. Whole human genome CNV was detected by using genechip from OncoScan Array platform designed by Affymetrix company, and the differences of gene segments were screened in the two groups. Results Nineteen samples of ESCC patients were collected to extract DNA in this study. To balance pair analysis in the two groups, 10 samples were selected from the qualified patients, including 5 cases in group S and 5 cases in group R respectively. There were no statistical differences in gender, age, lesion site, lesion length, radiation dose of the two groups (all P> 0.05). Loss of heterozygosity (LOH) was the main type of CNV. The analysis results showed that LOH in q24.32-q24.33 of chromosome 10 and LOH in q21.2-q21.31 of chromosome 18 had high frequencies (100 ％) in group R, however, none were detected in group S. LOH in q27-q28.1 of chromosome 4 had a high frequency (80％) in group S , however, none were detected in group R. Conclusion LOH in 10q/18q is related to radio-resistance in ESCC, and LOH in 4p is associated with radiosensitivity in ESCC.

OBJECTIVETo investigate the role of apoptosis stimulating protein 2 of p53 (ASPP2) phosphorylation status in the regulation of ASPP2-p53 apoptotic pathway activity.

METHODSCells were individually transfected with green fluorescent protein (GFP)-encoding vector, constitutively non-phosphorylatable ASPP2 mutant-ASPP2 (Am)-encoding vector, and wild type ASPP2 (Aw)-encoding vector) plasmids, respectively, to make them overexpressing phosphorylated and non-phosphorylated ASPP2 proteins, respectively. Cell apoptosis was induced by oxaliplatin. The apoptosis rate of cells was determined by flow cytometry after staining with FITC-conjugated annexin V and PI. ASPP2 protein level and its phosphorylation status were observed by Western blot. The interaction between ASPP2 and p53 was observed by immunoprecipitation assay.

RESULTSOxaliplatin induced cell apoptosis and caused phosphorylation of ASPP2 at ser92/ser361 in the HCT116 cells. The apoptosis rate of Aw and Am plasmids-transfected cells were (3.8 ± 1.0)% and (3.9 ± 1.2)% respectively, statistically with a non-significant difference (P > 0.05) in comparison with that of the GFP plasmid-transfected cells [(4.0 ± 0.8)%]. After oxaliplatin treatment, the apoptosis rate of Aw plasmid-transfected cells was (46.7 ± 3.9)%, significantly higher than that of the Am and GFP plasmid-transfected cells [(40.1 ± 10.2)% and (37.1 ± 6.9)%, respectively, P < 0.05], however, there was no statistically significant difference (P > 0.05) between Am and GFP plasmid-transfected cells. These results indicate that phosphorylated ASPP2 promoted the oxaliplatin-induced apoptosis of HCT116 cells through a p53-dependent pathway. Phosphorylation status of ASPP2 influenced its binding activity to p53.

CONCLUSIONPhosphorylation status of ASPP2 modulates p53 apoptotic function in oxaliplatin-induced apoptosis of colorectal cancer HCT116 cells.

Objective To compare and explore the optimal pathway of enteral nutrition between nasointestinal tube and nasogastric tube in patients with severe traumatic brain injury (sTBI). Methods One hunderd patients with sTBI, admitted to our hospital from January 2016 to December 2016, were divided into nasointestinal tube group and nasogastric tube group (n=50) according to different enteral nutrition pathways. The serum levels of tumor necrosis factor-α (TNF-α) and interleukin (IL)-6 were tested with enzyme linked immunosorbent assay (ELISA). Meanwhile, intestinal mucosal barrier function indexes D-lactate acid and intestinal fat acid binding protein (I-FABP) were evaluated by enzymology spectrophotometer method. On the admission, and one, 3, 7 and 14 d after treatment, gastrointestina complications, pneumonias and prognoses of the two groups were compared. Results As compared with those in the nasogastric tube group, the serum levels of inflammatory related factors (TNF-α and IL-6) in the nasointestinal tube group were significantly decreased 3 d after treatment (TNF-α: [112.77± 14.52] μg/L vs. [163.16±18.85] μg/L P=0.01; IL-6: [80.11±8.02] μg/L vs. [100.97±9.82], P=0.02). As compared with those in the nasogastric tube group, the intestinal mucosal barrier function indexes (D-lactate acid and I-FABP) in the nasointestinal tube group were significantly decreased 7 d after treatment (D-lactate: [47.51±4.87] μg/L vs. [62.20±6.01] μg/L, P=0.04; I-FABP: [29.12±3.74] μg/L vs. [40.08±5.51] μg/L, P=0.01). The nasointestinal tube group had significantly lower gastric retention incidence (18% vs. 28%, P=0.00) and aspiration incidence (14% vs. 26%, P=0.06). Meanwhile, the nasointestinal tube group had significantly lower incidence of pneumonia (24% vs. 34%, P=0.01), reduced pneumonia severity (clinical pulmonary infection scores [CPIS]: 14.27±1.22 vs. 17.30±1.50, P=0.03), better prognosis (GCS scores: (9.41±0.66 vs. 8.23±0.57, P=0.03; APACHE II scores: 14.27± 1.22 vs. 17.30±1.50, P=0.03) 14 d after treatment as compared with the nasogastric tube group. Enteral nutrition by nasointestinal tube could shorten the hospitalization days of patients (18.52±2.00 vs. 24.82± 2.31, P=0.02). Conclusion Enteral nutrition by nasointestinal tube can effectively reduce the incidences of gastrointestinal and pulmonary complications, and alleviate inflammatory response and intestinal mucosal barrier function damage in patients with sTBI, possibly improving prognosis.
