1.Maspin gene and the invasion and metastasis of gastric cancer
Journal of International Oncology 2014;41(3):209-211
The maspin gene,a tumor suppressor gene and a member of the serpin superfamily,is isolated from mammary epithelial cells.Maspin gene plays an important role in the process of invasion and metastasis of gastric cancer.Researches show that maspin gene suppresses the occurrence,development and metastasis of gastric cancer mainly by inducing tumor cell apoptosis,inhibiting tumor angiogenesis,methylation modification,promoting homogeneity adhesion and inhibiting heterogeneous adhesion.

Objective To determine plasma resistin level in patients with traumatic brain injury (TBI) and evaluate its correlations with outcome and inflammatory reaction. Methods Fiftyfour patients with moderate TBI, 71 patients with severe TBI and 40 healthy controls were enrolled in this study. Plasma samples were obtained from the healthy controls on physical examination and from the TBI patients on admission. Enzyme-linked immunosorbent assay ( ELISA) was used to determine the plasma resistin concentrations. Results Twenty patients (37.0% ) and 53 patients (74.6% ) with moderate and severe TBI suffered from an unfavorable outcome (defined as GOS score for 1-3 points) three months after TBI respectively. Plasma resistin levels in the patients with moderate and severe TBI were substantially higher than that in the healthy controls ((21. 9 ± 8. 4) ng/ml and (29. 2 ± 9. 6) ng/ml vs (9. 3 ± 2.6) ng/ml, both P <0. 01] by using covariance analysis. By using the multivariate linear regression analysis, plasma C-reactive protein level (t =2.212,P =0.035; t =2. 274,P =0. 014) and GCS scores (t =3. 120,P =0.007; t=3.986,P=0.003) were associated with the plasma resistin levels. Logistic regression analysis selected plasma resistin level as an independent predictor for 3-month unfavorable outcome of the patients with moderate and severe TBI (odds ratio = 1. 124, 95% CI = 1. 040-1. 221, P = 0.011; odds ratio = 1. 145, 95% CI = 1. 044-1. 232, P = 0. 009). A receiver operating characteristic curve identified cutoff levels of plasma resistin (22.4 ng/ml and 30.5 ng/ml) that predicted 3-month unfavorable outcome of moderate and severe TBI patients with the high sensitivity (70. 0% and 79. 2% ) and specificity (70.6% and 72.2% ) ( area under curve = 0.719, 95% CI = 0.642-0.829, P = 0.000;area under curve =0.735, 95% CI =0. 671-0. 893, P = 0.000). Conclusions Plasma resistin level is increased after TBI and may be involved in inflammatory response of brain injury. Clinical detection of this indicator can help early determine the prognosis of the TBI patients.

Objective To explore the value of the apparent diffusion coefficient (ADC)of MRI diffusion-weighted (DW)in diag-nosing pathologic stage and histologic grade of bladder cancer.Methods 42 patients with confirmed bladder cancer underwent pelvic MRI examination including T2 WI and diffusion-weighted imaging (b values of 0 and 1 000 s/mm2 )Based on pathologic results,42 cases of bladder cancer were divided into three groups of Ta-T1 stage (non-muscle invasive),T2 stage (muscle invasive)and T3-T4 stage (around the bladder and other organizations invasive).Of 42 bladder cancers,36 urothelial carcinomas were divided into papillary urothelial neoplasm with low malignant potential (PUNLMP),low grade urothelial carcinoma and high grade urothelial carcinoma group.Tumor diameter and ADC were measured on DW imaging,and compared among different groups.Results The mean size of high grade tumors (4.52 ± 1.61)cm was significantly larger than that of PUNLMP (2.28 ± 0.51)cm and low grade tumors (1.69 ± 0.53)cm.The mean ADC of high grade tumors (0.83 ± 0.27)×10-3 mm2/s was significantly lower than that of PUNLMP (1.46 ± 0.30)×10-3 mm2/s and low grade tumors (1.17±0.11)×10-3 mm2/s (P<0.01).T3-T4 stage tumors showed significantly lower ADC (0.82±0.21)×10-3 mm2/s than T2 (1.01 ± 0.09)×10 -3 mm2/s and Ta-T1 stage tumors (1.24 ± 0.13)×10 -3 mm2/s (P <0.01).Conclusion DW ima-ging combined with conventional MR sequences is useful for displaying morphology of bladder cancer.DW imaging and ADC are use-ful in evaluation of pathologic stage and histologic grade of bladder cancer.

Objective:To observe the effect of Gemcitabine ( GEM) on the viability and apoptosis of non-small cell lung cancer HCC827 in vitro. Methods:The cell viability,apoptosis and cell cycle of HCC827 cells induced by Gemcitabine were detected with cell counting kit-8 assay (CCK-8),Annexin V-FITC/PI staining and flow cytometry. The expression of Bcl-2 protein of cells treated with GEM was examined by Western blot assay. Results: There was significant inhibition effect on HCC827 cells treated with 0. 1-1 000 ng/ml of GEM,which can promote the occurrence of HCC827 cell apoptosis and arrest cell in the S phrase. The apoptosis induced by GEM was accompanied with the down regulation of Bcl-2 protein. Conclusion: GEM can inhibit the cell viability and induce the HCC827 cell apoptosis and S phrase arrest. Its cell dead type was apoptosis,which was related with the expression of Bcl-2 protein.

Objective To investigate the distribution and drug resistance of bacteria in 1 -6 months infants with lower respiratory infection(LRI).Methods Induced sputum was extracted from 326 infants with LRI who were 1 -6 months.Antibiotic susceptibility tests were performed after bacteria had been identified.Results 61 cases were detected pathogenic bacteria and the detection rate of bacteria was 18.71%.5 cases were detected two kinds of bacte-ria.66 bacterial strains were isolated among which gram -positive bacteria(33 strains)accounted for 50.00% and gram -negative bacteria(33 strains)accounted for 50.00%.Staphylococcus aureus was the most common gram -pos-itive bacteria and Streptococcus pneumoniae was the second.13 strains were methicillin -resistant Staphylococcus au-reus(MRSA).Hemophilus influenzae was the most common gram -negative bacteria,followed by Klebsiella pneumo-nia and Escherichia coli among which ESBL positive Klebsiella pneumonia were 5 cases and ESBL positive Escherich-ia coli were 4 cases.The common gram -positive bacteria had higher rate of penicillin resistance.MRSA had higher rate of penicillin,oxacillin,erythomycin and clindamycin resistance.Resistant strains to vancomycin and rina thiazole amine were not found.The common gram -negative bacteria had higher rate of ampicillin,ampicillin/shu tan,cefazo-lin and ceftriaxone resistance and had lower rate of cefepime,ceftazidime,piperacillin/he azole temple and imipenem resistance.Conclusion The common pathogenic bacteria in 1 -6 months infants with lower respiratory infection were Staphylococcus aureus,Hemophilus influenzae,Streptococcus pneumoniae,Klebsiella pneumonia and Escherichia coli. We should pay attention to the common antibiotic resistance.MRSA and ESBL positive bacteria were the common mul-tiple drug resistant bacterias.Reasonable selection of antibiotics should be based on susceptibility results earlier.

ObjectiveTo investigate the clinical effects of systems integrative rehabilitation therapy for cervival spdylotsis myelopathy.MethodsFrom April 2002 to October 2004, 68 cases were intervened with the integrative rehabilitation treatment, which linked up the pre- and post-operational rehabilitation interventions into a continuum. The cases were followed up, and serial radiological evaluations were applied. Then the height of involved interspinal space was measured preoperatively and 12 months after operation, and the spinal function was evaluated according to the standard of Japanese Orthopeadic Association (JOA).ResultsAll the cases were followed up, of which 49 were better, 1 was improved, none was worsened. 12 months after operation, roentgenographic appearance showed that the allograft healing and interbody fusion of all patients were achieved, and the reserving height of involved interspinal space and JOA evaluation postoperatively were significantly superior to preoperatively. There was no complications such as cervical spinal cord injury, internal fixation loosening and hematoma turned up.ConclusionThe integration rehabilitation therapy has satisfactory effects in the cervical spondylotsis myelopathy.
