Objective To analyze the correlation between 18F-FDG SUV and immunohistochemical index including GLUT1, Ki-67, MVD, survivin and cyclinA in non-snall-cell lung cancer. Methods Thirty-three patients with NSCLC underwent preoperative PET/CT examination and surgical operation. All patients were divided into two groups according to the size of tumor (cutoff=3 cm), metastasis of mediastinal or hilar lymph nodes or not, and histological types of the cancer, respectively. The expression of GLUT1, Ki-67, MVD, survivin and cyclinA were estimated with SP immunohistochemical technique, and were analyzed statistically to reveal the correlation to FDG SUV. Results The rate of positive expression of GLUT1, Ki-67 and CD34 were 66.67%, 72.73% and 100%, respectively. The mean value of CD34 in all 33 patients was 12.6±2.9 (12-56). The rate of positive expression of survivin was 84.85%, and the corresponding data of cyclinA was 27.27%. Conclusion There is linear correlation between FDG PET SUV and GLUT1, but not between FDG PET SUV and Ki-67, MVD, survivin and cyclinA. The expressions of GLUT1, Ki-67, MVD, survivin and cyclinA are not related with the size of tumor, nor metastasis of lymph nodes. The expression of GLUT1 and Ki-67 is related with histological types of the cancer, but not with MVD, survivin and cyclinA.

Objective To investigate the clinical outcome of post-traumatic tibial osteomyelitis treated by induced membrane technique combined with the antibiotic cement-coated locking plate.Methods A restrospective case series analysis was made on 71 cases of post-traumatic tibial osteomyelitis treated by induced membrane technique from September 2014 to September 2014.There were 55 males and 16 females, aged 18-60 years(mean, 37.4 years).Mean length of bone defect following debridement was 4.5 cm(range, 4-11 cm).Antibiotic cement-coated locking plates were used to provide the stability of the bone defects after one-stage debridement.Bone grafting and exchanging the plates with ntramedullary nails were done during the second-stage surgery.Parameters were monitored dynamically after operation to evaluate infection recurrence and bone healing, including C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), clinical features(sinus formation, redness and swelling, warmth and pain) and X-ray films of the involved limbs.Results All patients were followed up for 13-25 months (mean, 19.5 months).There was no sign of recurring infection and CRP and ESR were normal in all cases after the first stage surgery.However, four cases (6%) had recurrent infection with sinus exudates and their CRP and ESR were abnormal after the second stage surgery, and further treatments were carried out on these patients.Follow-up showed bony union in all patients within mean 5.5 months (range, 4-6 months).Conclusion Induced membrane technique with antibiotic cement-coated locking plates for treatment of post-traumatic tibial osteomyelitis can shorten bone healing time and decrease infection recurrent rate without obvious impact on osteogenic activity.

Data is the basis and soul of clinical trials. To obtain accurate data, strict and standard data management is essential, which can be effectively supported by quality control in statistical analysis. In this paper, we briefly introduce the concept of the quality control in clinical trials, and describe its contents and methods. We hope that this work will be helpful to the application of statistical quality control in data management of clinical trials.

Objective To prospectively investigate the characteristics and correlative influential factors for the changes in pulmonary artery hypertension (PAH)in chronic kidney disease (CKD) patients without end-stage renal disease.Methods Complete clinical and laboratory data of 133 outpatients without ESRD (CKD stage 2,3 and 4)in Beijing Hospital between January 2012 and January 2013 were retrospectively analyzed.Pulmonary artery systolic pressure(PASP)was assessed by echocardiography according to the guideline from the American Society of Echocardiography in 2010,and PASP more than 35 mmHg(1 mmHg=0.133 kPa)was diagnosed as PAH.Results PAH was found in twelve(9.0 ％) patients,including 7 females and 5 males,with mean age(82.9 ± 5.4 years).The prevalence of PAH was 2.3％,10.9％ and 17.6％ in the patients of CKD stage 2,3 and 4(P＜ 0.05) respectively.PASP could be calculated in 67 patients in whom tricuspid regurgitation was present.The mean PASP was (27.1 ± 5.4) mmHg,(31.0 ± 8.3) mmHg and (37.3 ± 13.8) mmHg in patients with CKD stage 2,3 and 4,respectively(P ＜ 0.05).Body mass index(BMI),eGFR and BUN showed significant differences between PAH group and non-PAH group with statistical significance (P＜0.05).Multivariate logistic regression analysis revealed that the lower BMI and the higher stage of CKD were independent risk factors for PAH (P ＜ 0.05).Conclusions PAH is not a rare complication in the CKD patients without end-stage renal disease.The incidence of PAH is significantly associated with lower BMI and the higher stage of CKD.Doppler echocardiography should be performed periodically to detect PAH in CKD patients in order to improve the prognosis of these patients.

Objective To explore the operative cooperation of the intra-extra cranial bypass operation of the intracranial giant aneurysms. Methods A retrospective analysis of 7 patients who had intracranial giant aneurysm and received the intra-extra cranial bypass operation from October 2014 to June 2016. All preoperative and intraoperative nursing points of operative cooperation were analyzed. Results The post-operative digital subtraction angiographies of 7 patients without any perioperative nursing complications showed enough flow in the bypass arteries. Conclusions Operative multi-incision managing, positive temperature intervening, special instruments using and thrombosis preventing play very important roles in the nursing points of the successful operative cooperation.

Abstract: Occupational epidemiology aims to explore the effect of occupational hazards on the health of workers and understand ， their mechanisms. It plays an important role in occupational health and occupational medicine.Currently occupational ， ， exposures in the workplace are complex and diverse and multiple factors affect workers´ health at the same time. Therefore it is important to elucidate the pathogenesis of occupational disease caused by occupational hazards and implement early - - intervention. System epidemiology collects data on multi level exposure and multi omics information to conduct network analysis - on the relationship amongrisk factors. and to study the mechanisms of exposures and health outcomes based on multi level data. ， ， ， ， Using the study design of system epidemiology occupational environmental lifestyle and social factors are combined as a ， system to evaluate the health of workers which can better evaluate the adverse health effects caused by occupational hazards. - ， ， The studies base on multi omics design will explore the pathogenesis of occupational diseases at the molecular cellular and tissue levels to evaluate the impact of occupational hazards on workers´ health and to explore interventions from multiple - perspectives to reduce the occurrence of occupational or work related diseases.

ObjectiveTo explore the changes of serum high sensitive C-reaction protein (HS-CRP) and matrix metalloproteinase-9 (MMP-9) in patients with acute coronary syndrome (ACS) and their effects in nursing.Methods103 ACS patients, including 56 cases of unstable angina (UA)) and 47 cases of acute myocardial infarction (AMI), and other 40 persons (no abnormal results in coronary artery angiography, selected as control group) were examined for serum levels of HS-CRP and MMP-9. The difference among the groups was analyzed.ResultsThe HS-CRP levels of UA group, AMI group and control group were (3.87± 0.76 )g/L, (4.12 ±0.67)g/L and (1.67±0.38)g/L respectively; MMP-9 were (113.25±7.76)ng/ml, (193.09±25.87)ng/ml and (42.05±3.81)ng/ml respectively. The concentrations of HS-CRP and MMP-9 of ACS patients were significatly higher than those of the control group (P<0.01).ConclusionThe changes of HS-CRP and MMP-9 concentrations of ACS patients are remarkable, and may be as the markers to instruct nursing works.
