Objective To explore the clinical curative effect on non-small cell lung cancer (NSCLC) patients by cinobufacini injection combined with first-line chemotherapy.Methods Eighty patients with NSCLC from January 2013 to January 2015 in our hospital were selected as the research objects.Then they were divided into the observation group (n =40)and the control group (n =40)by random number tables.The patients in control group accepted docetaxel and cisplatin combination chemotherapy regimens (TP).While the observation group accepted cinobufacini injection on the basis of the control group.Then the local control, adverse reactions and prognosis of the two groups were compared.Results The local control of observation group was 77.5%,while the control group was 62.5%,the local control of observation group was obviously higher than that of the control group (χ2 =5.36,P =0.03).Leucopenia incidence of the observation group was 27.5%,the control group was 50.0%,and the incidence of the observation group was obviously lower than that of the control group (χ2 =4.27,P =0.04).There was no statistically significant difference between the two groups in diarrhea,stomachache,vomiting,tinnitus (17.5% vs.27.5%,χ2 =1.15,P =0.28;25.0% vs.45.0%,χ2 =3.52,P =0.06;5.0% vs.7.5%,χ2 =0.34,P =0.56;7.5% vs.10.0%,χ2 =0.16,P =0.69).There was statistically significant difference between the two groups in median survival time (97 d vs.45 d,HR =8.934,χ2 =9.928,P <0.05).Conclusion The cinobufacini injection combined with docetaxel can effectively reduce the incidence of myelosuppression,and improve survival and local control with high safety,and the clinical effect is remarkable and can improve the prognosis of patients.

Objective:To investigate the possibility and feasibility of the simultaneous coronary artery bypass grafting (CABG) with tumor excision in patients suffering from tumor combined with coronary artery disease(CAD). Methods:From August 2000 to July 2006, ten patients who were suspected of tumor (four patients suffered from urinary system tumor, two digestive system tumor, and four pulmonary tumor) with coronary artery disease were successfully treated by simultaneous surgeries. Surgical incisions were chose by the different tumor position. All carried on the CABG before tumor excision except one case. The two cases had cardiopulmonary bypass CABG, the rest eight had off-pump CABG. Follow-up was conducted after operation. Results:The combined operations were satisfied. There was no in-hospital mortality, no postoperative hemorrhage, no myocardial ischemia or infarction, with few complications. Postoperative in-hospital stay was 10-34 days, average 22.4 days. All discharged in cure. One patient lost the follow-up. Nine patients were followed up from six months to seven years three months. Two patients died from metastasis, and the others survived with satisfied follow-up without cardiovascular events. Conclusion:The simultaneous coronary artery bypass grafting with tumor excision for patients who suffer from either CAD with benign or malignant tumor is safe and feasible with satisfied short-and long-term survival.

Objective To investigate the changes of plasma adrenodullin(ADM) and C-type natriuretic peptide(CNP) level in children with chronic heart failure(CHF) and its clinical implications.Methods Forty-two children with CHF were collected.The patients suffered from dilated cardiomyopathy,congenital heart defects,and other heart diseases.According to a modified scoring system described by Ross and Reithman,16 patients were classified as class Ⅱ,14 as class Ⅲ,and 12 as class Ⅳ.Plasma levels of ADM and CNP were measured by radioimmunoassay assay in these patients and 11 healthy children.Echocardiography was performed to measure left ventricular function and the ratio of E/A.Results Plasma ADM and CNP levels of CHF patients were significantly elevated as compared with those of the control subjects [(218.27?106.53) ng/L vs(74.39?53.99) ng/L,P=0;(190.27?108.38) ng/L vs(92.59?(59.46) ng/L),P0.05).ADM levels were elevated with the advancing severity of CHF determined by a modified scoring system described by Ross.However,the plasma CNP levels in the normal state wasn′t significantly different from those observed in class Ⅱ.Likewise,the plasma CNP level in the class Ⅲ was not significantly different from that observed in class Ⅱ.Conclusions ADM and CNP might play a compensatory and defensive roles in the pathophysiology of the pediatric CHF.ADM may be a biochemical marker for evaluation the severity of the chronic heart failure in children,but also a new prognostic indicator of this syndrome.

Objective To dynamically monitor the blood glucose in traumatic brain injury (TBI) patients within three days after admission, and to assess the impact of hyperglycemia on prognosis. Method Between 2007 and 2008, 62 TBI patients, who were admitted within 6 hours after the ineidence of injury without diahetes or severe combined injuries, were involved in this study. Blood glucose was monitored at 4 time points (instantly, 24 hours, 48 hours, and 72 hours after admission). Patients were classified into the mild, the moderate, or the se-vere TBI group according to GCS (Glasgow Coma Scale) scores, being classified into the survival or the dead group according to prognosis, or into the mile or severe hyperglycemia group depending on whether the blood glucose ex-ceeds 11.1mmol/L on admission. T tests and χ2 tests were applied to analyze the relationship among blood glucose levels, the degrees of injury, and the prognosis of studied patients. Results Patients with mild, moderate, or se-vere TBI showed hyperglycemia with different levels, and the blood glucose levels was consistent with the degree of the injury. The blood glucose of the patients in the dead group were significantly higher at all checked time points than those of the survival group, particularly instantly after admission (8.51±2.01 mmol/L vs. 11.54±2.45 mmol/L, P=0.0001, t=4.988). The mortality of patients with severe hyperglycemia was 64.71%, signifl-candy higher than that of the mild hyperglycemia group 13.95% (P=0.0002, χ2=15.46). The Intensive Care Unit Length of Stay (ICULOS) of the above two groups was 22.6 and 10.2 days,respectively (P=0.021, t= 3.216), but their hospital length of stay (HLOS) showed no statistical difference (P=0.052). Conclusions Hyperglycemia, as an early stress response to TBI, may reflect the degree of the injury. Blood glucose levels that exceed 11.1 mmol/L on admission may imply high mortality of TBI patients, so this could be used as a simple indi-cator to predict prognosis.

Background Studies demonstrated that human amniotic epithelial cells (AECs) have some characteristics of embryonic stem cells and they were used to re-establish the surface of eyes. Human AECs may serve as new seed cells in tissue engineering for corneal epithelium reconstitution in the future. Objective The present study was to investigate the application value of human amniotic epithelium cells transfected by lentiviral vectormediated enhanced green fluorescent protein (EGFP) gene as new seed cell source for engineering the corneal surfacelayer. Methods Lentiviral vector carrying the objective gene EGFP was transfected into human amniotic epithelial cells (pLenti6/V5-DEST),and the transient expression of the transgene in the human amniotic epithelial cells was observed under the fluorescence microscope. Flow cytometry was used to detect the positive expression rates of EGFP in transfected cells. The transfected human amniotic epithelial cells were seeded onto the fresh corneal stromal surface of New Zealand white rabbit and cultured in vitro. The stem cell deficiency ( SCD ) models were established by cutting off the limbus of cornea in 20 eyes of New Zealand white rabbits, and the model rabbits were then divided into 2 groups randomly. The transplanted grafts carrying the pLenti6/V5-DEST-EGFP gene-transferred human amniotic epithelium cells were regarded as the pLenti6/V5-DEST-EGFP group, and the corneal stroma graft without any epithelial cell served as the control group. The opacity of stroma and corneal conjunctivalization and vascularization were observed daily. The rabbits' eyes were extracted one month after operation. The expression of EGFP in the cornea was detected under the fluorescence microscope, and the expression of CK8, CK18 and CK12 in cornea was detected by immunohistochemical staining. Results The shape of the transferred human amniotic epithelial cells resembled normal human amniotic epithelial cells. 48 hours after the transient transfection of EGFP presented with the highest expression level throughout the observation duration, with a positive expression rate of EGFP of 61.5% ,showing significant differences in comparison with that of 12 ( 5.24% ) , 24 ( 38.27% ) or 96 ( 39. 10% ) hours ( P ＜0. 05) post-transfection; but no obvious difference was found in the positive rate of transiently transfected EGFP between 48 hours and 72 hours ( 58.36% ) ( P＞0. 05 ). Six cornea grafts were clear in 1 month and two corneas were rejected during the observation period in the pLenti6/V5-DEST-EGFP group. A few new blood vessels were seen around the graft. Ten corneas of the control group became opaque and cloudy with new blood vessels growth around the grafts. Imunohistochemistry revealed the positive expressions of CK8, CK1 8 and CK12 in the corneal epithelial layer in the pLenti6/V5-DEST-EGFP group. However,the expression of CK12 was absent in the control group. Conclusion Human amniotic epithelium cells transfected with the pLenti6/V5-DEST-EGFP gene is a new and ideal feed cell type to reconstruct the corneal surface layer. Lentivirus is a relatively safe gene transfection vector.

Objective To explore the imaging features and dynamic CT findings of primary adrenocortical carcinoma and evaluating its clinical value.Methods All 11 cases patients with primary adrenocortical carcinoma confirmed by surgical pathology underwent spiral CT plain scanning and two phases dynamic enhancement scanning before operation.Contrast injection was done by using nonionic Omnipaque at a flow rate of 3 ml/s with a power injector.The CT images were reviewed and analysed retrospectively in comparison with surgical and pathological results.Results Five of 11 lesions were located in the right adrenal gland,6 in the left.The diameter of the tumors was 4.1—16.0cm with 2 cases10.0cm.The attenuation of the plain scans,two phases contrast scans was 21.9—46.7 HU(with a mean value of 35.3 HU),30.5—65.8 HU(mean value 47.1 HU),and 52.6— 97.0 HU(mean value 74.2 HU),respectively.Four were in the shape of capsule,6 reticular,1 slightly inhomogeneous masses.The irregular tumor vessels of 6 reticular masses were seen in the artery phase. Conclusion The dynamic CT features of primary adrenocortical carcinoma were obvious,dynamic SCT scans could suggest the diagnose.

Objective CD4 +IL-17 +cells are a group of newly discovered effector CD4 +T cells, which may play a key role in the pathogenesis of cancer.This study aims to investigate the expres-sion of CD4 +IL-17 +cells in pancreatic cancer and its correlation with the clinicopathological characteristics and prognosis of the dis-ease as well as the clinical significance of the cells in the microenvironment of pancreatic cancer. Methods We collected tumor tis-sue and tumor-adjacent normal tissue samples from 51 pancreatic cancer patients.We determined the expressions of CD34 and vascular endothelial growth factor ( VEGF) and measured the proportion of IL-17 +cells in the cancer tissue using immunohistochemistry and the fluorescence activated cell sorter, respectively, followed by analysis of their correlation with tumor angiogenesis, clinicopathological pa-rameters, and survival time of the patients. Results The percentage of CD4 +IL-17 +cells in tumor tissue was positively correlated with microvessel density (r =0.534, P<0.05) and the expression of VEGF in the tumor tissue (r=0.356, P<0.05).IL-17 +cells were expressed more highly in the tumorous than in the tumor-adjacent normal tissue (P<0.05), and the expression level was correla-ted with the stage of tumor, node, and metastasis (TNM) and lymph node metastasis (P<0.05), but not with the patients′gender or age, tumor size, tumor location, histological grade, or local invasion (P>0.05).Fifty (98.0%) of the patients were successfully followed up for 2-67 months, which revealed a median survival time of 16.6 ±4.8 months, significantly longer in those with a higher expression of intratumoral IL-17 +cells (P<0.05).Univariate analysis showed an association of the survival rate with the tumor size, TNM stage, lymph node metastasis, and level of intratumoral IL-17 +cells, while multivariate analysis showed the TNM stage to be an independent prognostic factor for the survival of the pancreatic cancer patients. Conclusion The expression of CD4 +IL-17 +cells in the tumor tissue is positively correlated with tumor angiogenesis, while that of IL-17 +cells with the clinicopathological parameters and survival time of the patients and therefore may serve as an important immune indicator for the prognosis of pancreatic cancer.
