Objective To determine the evaluating prognostic value of plasma Nt-proBNP in patients with congestive heart failure.Methods 107 patients with congestive heart failure were included in this study,followed the degree of rehospitalization and mortality rate of the cured patients after left hospital.The plasma concentrations of Nt-proBNP were measured by enzymelinked immunozorbent assay(ELISA).Results Concentrations of Nt-proB-NP of Ⅱ,Ⅲ,Ⅳ classincation were(1129.8±383.2),(5849.7±567.6),(9506.3±492.4)ng/L in NYHA functional classification respectively(P＜0.01);the plasma level of Nt-proBNP had significant positive correlation with NYHA functional classification(r=0.759,P＜0.01).The degree of rehospitalization were(0.85±0.96),(1.98±0.86),(2.58±0.91)respectively(P＜0.01);mortality rate were 8.3%,12.5%,45.2%respectively(P＜0.01).Conclusion Plasma Nt-proBNP level may be the more important clinic value in evaluating prognosis in patients with congestive heart failure.

Objective To observe the inhibitory effect of Gefitinib,a selective oral epidermal growth factor receptor tyrosine kinase inhibitor,on the growth of human colon cancer cells,and investigate the relationship between the sensitivity of colon cancer cells to Gefitinib and PIEN expressions.Methods The inhibitory effects of Gefitinib on 6 kinds of colon cancer cells(Lovo,HCT116,HT29,Lsl74T,SW480 and SW620),the levels of PTEN mRNA in different colon cancer cells.and PTEN protein expressions in colon cancer cells were detected by MTT assay,RT-PCR and Westem blot,respectively.Results The inhibitory effects of Gefitinib on the 6 colon cancer cells in vitro varied a lot.When the concentration of Gefitinib was 1 μmol/L,LoVO cells had the most sensitivity to Gefitinib with an IC50＜10μmol/L;HT29 and SW480 had moderate sensitivity,and the IC50 ranged from 10 μnol/L to 100 μmol/L;HCT116,LS174T and SW620 were insensitive to Gefitinib,and their IC50＞100 μmol/L.All the colon cancer cell lines exhibited PTEN mRNA and protein expressions.Conclusions PTEN mRNA andprotein expressions might not be associated with the inhibitory effects of Gefitinib on the growth of colon cancer cells.The expression of PTEN can not be taken as the indication of the sensitivity of colon cancer cells to Gefitinib.

Objective To evaluate the dose distributions with different dose rates, and approach a reference to the dose rate for radiation. Methods Three classic static intensity modulated radiotherapy (IMRT) plans of prostate cancer, lymphoma and nasopharyngeal carcinoma were chosen for the study. For each plan, the dose verification of three different dose rates (100, 300 and 600 MU/min) was performed with the Varian 600CD linear accelarator by using the 2-DICA of I'mRT Matrixx. With the Pinncale planning system, each segment was used as a beam to form another IMRT plan. The OmniPro-I'mRT V1.6 was applied to compare the segments in the two IMRT plans, and then the actual weights were obtained. The simulated plans at different dose rate were designed when setting the weights back into the planning system. Results With the increase of dose rate, the passing ratio of the verification decreased and the D_(max), D_(min), D_(mean) and D_(95) of the planning tumor volume increased. The high dose area expanded significantly in target regions, and the 95% isodose line extended. At the dose rate of 600 MU/min, The D_(95) of GTV_(nd) in nasopharyngeal carcinoma increased by 5.33% than the original plan with the V_(110) up to 19. 38%. The irradiation dose of the organs at risk (OARs) increased. For the case of lymphoma, the V_(20) of the lungs in the original plan and the three simulated plans were 31.77%, 32. 11%, 32.60% and 33.26%, respectively. For the case of nasopharyngeal carcinoma, the V_(30) of the right parotid were 48.75%, 49. 56%, 51.65% and 53.91%, respectively. Conclusions With the increase of dose rate in static IMRT , the actual dose distribution deviates the original plan , and the high dose area and the OARs dose increases. The higher dose rate is suboptimal when the dose of the OARs is proximate to the tolerance limit.

Objective: To use vertical and humidity correcting method to calibrate aerosol optical depth (AOD), and to explore the feasibility of calibrated-AOD as exposure index to measure the level of air pollutants from the ground and to establish the exposure-response relationship between calibrated-AOD and people's health outcomes.Methods: First of all, we interpolated AOD, PM2.5, relative humidity and planetary boundary layer height using Kriging method to obtain data at different locations and matched different data with respiratory death in Beijing by geographical coordinates.Then, the planetary boundary layer height and aerosol hygroscopic growth factor calculated based on relative humidity was used to calbrate the AOD.To compare the effects of calibrated-AOD and PM2.5, we used standardization method to get non dimensionless calibrated-AOD and PM2.5.At last, we used the generalized additive mixed model (GAMM) to estimate the acute effects of calibrated-AOD and PM2.5 on respiratory death and chronic obstructive pulmonary disease (COPD) death, after controlling the time trend, temperature and humidity effects, days of the week effect and holiday effects.Results: The correlation coefficient between calibrated-AOD and PM2.5 was 0.72.The effects of calibrated-AOD on respiratory death and COPD death was the strongest at lag 0-3, one unit of calibrated-AOD increases was associated with 3.64% (95%CI: 0.58%-6.78%) increase of respiratory death and 4.92% (95%CI: 1.81%-8.14%) increase of COPD death.As for PM2.5, the strongest effects appeared at lag 0-1, one unit of PM2.5 (about 155 μg/m3) increases was associated with excess risks of 3.96% (95%CI: 0.82%-7.19%) and 6.12% (95%CI: 1.44%-11.02%) for respiratory death and COPD death respectively.Compared with PM2.5, the effects of calibrated-AOD on respiratory death and COPD death had narrower confidence intervals.The calibrated-AOD was sensitive to capture the lag effects, and the cumulative lag effects of calibrated-AOD were all significant on multiple lag days which indicated that the calibrated-AOD was sensitive to capture cumulative lag effects of air pollutants on respiratory death and COPD death as well.Conclusion: We believe that calibrated-AOD can be used as an index to reflect the effects of air pollutants on respiratory death in Beijing.In the absence of ground monitoring, calibrated-AOD can be used to mea-sure the relationship between air pollutants and some health outcomes.

OBJECTIVE:To investigate the characteristic and regularity of antineoplastics-induced ADR,and to provide refer-ence for safety use of antineoplastics in clinic. METHODS:In retrospective study,309 cases of antineoplastics-induced ADR col-lected from a special hospital during Jan.-Dec. 2015 were summarized and analyzed statistically. RESULTS:Among 309 ADR cas-es,female (58.25％) was more than male (41.75％). The patients aged more than 40 years old occupied the highest proportion (78.64％). Main route of administration was intravenous dripping(94.82％). There were 225 cases of severe ADR(72.82％). To-tal 268 cases were improved after drug withdrawal or treatment(86.73％). A total of 24 kinds of antineoplastics were involved in 309 ADR cases;most of ADR were induced by docetaxel,followed by cisplatin,cyclophosphamide. Most common organs/system involved in ADR was hemopoietic system (64.24％),main clinical manifestation was myelosuppression. CONCLUSIONS:It is necessary to strengthen ADR monitoring,prevent,discover and treat antineoplastics-induced ADR timely,in order to reduce the harm to the patients and ensure the safety and effectiveness of drug treatment.
