Objective:To evaluate the efficacy and safety of sequential platinum regimen in young patients with diffuse large B-cell lym-phoma (DLBCL). Methods:Newly diagnosed young patients with DLBCL, who were hospitalized from January 2005 to June 2012 in the Affiliated Cancer Hospital of Zhengzhou University, were selected according to the requirements. The patients were divided into stan-dard and sequential platinum regimen groups. The remission rates were compared usingχ2 test, whereas the five-year survival rates between the two groups were compared using the Kaplan–Meier method. Multivariate survival analysis was performed using the Cox proportional regression. Subgroup analysis was conducted to select candidate patients for the sequential platinum regimen. Results:A total of 331 patients were enrolled in the study, in which 129 were provided with sequential platinum regimen and 202 were provided with the standard regimen. Sequential regimen yielded higher rates of complete remission (80%vs. 63%, P=0.001), five-year progres-sion-free survival (PFS;60%vs. 50%, P=0.014), and overall survival (OS;70%vs. 58%, P=0.016) than the standard regimen. Multivariate analysis revealed that sequential regimen was an independent prognostic factor for PFS (hazard ratio HR=0.635, P=0.012) and OS (HR=0.625, P=0.021). Subgroup analysis showed that patients with good prognosis and patients who did not receive rituximab benefited more from the sequential platinum regimen. Sequential platinum regimen did not increase the occurrence of adverse effects com-pared with the standard regimen. Conclusion:Sequential platinum regimen is a safe treatment that can improve the survival of young patients with DLBCL. Patients with good prognosis and patients who did not receive rituximab can benefit more from the treatment with sequential platinum regimen.

Objective To investigate the value of two-dimensional speckle tracking imaging (STI) in assessing regional myocardial dysfunction and myocardial fibrosis in a mouse model of myocardial infarction.Methods Twenty C57/B6 mice were randomly divided into two groups:myocardial infarction (MI) group (n =10) and sham-operation (SO) group (n =10).Echocardiography was performed four weeks after surgery.High frame rate two dimensional images were recorded in the left ventricular short axis views at the papillary muscle level and analysised at EchoPac workstation.Peak radical strain (PRS) and peak radical strain rate (PRSR) of each segment were measured at systolic period.Percent segmental fibrosis (PSF) was assessed from histological left ventricular cross sections stained by Masson trichrome.Results Compared with SO group,PRS and PRSR decreased significantly in all segments of MI group (P < 0.01),especially in anterosepetal,anterior and lateral segments (P <0.05).PSF of anterosepetal,anterior,lateral and posterior segments in MI group increased significantly than those in SO group(P <0.01),and were negatively correlated with PRS and PRSR of these segments(r =-0.88,P <0.001 ; r =-0.77,P <0.001).Conclusions STI could accurately quantify regional myocardial function in a mouse model of myocardial infarction.Segmental radial strain and strain rate measured by STI were significantly correlated with PSF,which can be a non-invasive tool for monitoring myocardial fibrosis after myocardial infarction.

OBJECTIVETo study the relationship between compositions of hyperuricemia and metabolic syndrome among residents aged > or =20 years.
METHODSA stratified cluster sampling was conducted with 7887 dwellers recruited and examinaed. Blood samples were then collected for serum detection. Available data was analyzed using SPSS 13.0.
RESULTSThe incidence rates of obesity, hypertension and hyperglycemia for hyperuricemia were 53.4% with OR = 2.568 (95% CI: 2.103-3.137), 38.8% with OR= 2.157 (95% CI: 1.856-2.508) and 21.9% with OR = 1.850 (95% CI: 1.552-2.205) respectively. Along with the increase of uric acid, body mass index changed the most followed by triglyceridemia. The change of hyperglycemia for men and cholesterol for women were not prominent. Conclusion The relationship between compositions of hyperuricemia and metabolic syndrome was close, suggesting that hyperuricemia might serve as one of the compositions of metabolic syndrome and could contribute to the prevention and control of cardiovascular and cerebrovascular diseases.

OBJECTIVETo explore the lung cancer incidence rates from 1972 to 2001 and utilize varieties of models in forecasting trend up to 2010 in the city of Qidong, Jiangsu in order to provide baseline data for its control and prevention.
METHODSUsing data from the cancer registry office in Qidong, we tried to reveal the trends of lung cancer incidence by analyzing the time-series on trends extrapolation, exponent smoothness, Box-Jenkins model etc. We also compared the prognostication precision, endow differ power, and established assembled forecast model.
RESULTSData showed that there had been a rising trend of lung cancer from 1972 to 2001 and would still probably be on the increase in the future. The rate of male and female attained to 70 per 100 000 and 20 per 100 000, predicting that there would be a respective 33 percent and 10 percent increase in 2010.
CONCLUSIONSAccording to analysis of forecast models, it was right to prognosticate lung cancer incidence from time-series and improve forecast precision through developing combination models. The result of combination seemed close to ARIMA models which suggested that it could serve as a chief way to forecast the incidence of lung cancer.

Objective:To discuss the topical action characteristics of the biological transmission of moxibustion heat via temperature collection and numerical modeling.Methods:Temperature of moxibustion was measured at multiple points at a distance of 3 cm to obtain the moxibustion temperature field nephograms by the high-accuracy temperature measure array.Finite element analysis was used to imitate the three-dimensional dynamic distribution of temperature in acupoint tissues.Results:Through numerical analysis,the one-dimensional,two-dimensional and three-dimensional distributions of temperature in human acupoint tissues at 5 min of moxibustion were established.The result showed that moxibustion heat mainly transmitted from the surface of the tissue to the internal,and the influence of moxibustion heat decreased with the depth of the tissue.The analysis of the nephograms of acupoint tissue temperature at 5,10,15 and 20 min of moxibustion showed that with the increase of the moxibustion time,the temperature in acupoint tissues constantly rose,and the transmission depth of moxibustion heat also further expanded inside acupoint.Conclusion:By establishing the three-dimensional dynamic model of heat transmission inside acupoint tissues with the biological parameters of human tissues and the temperature values obtained,this study used finite element analysis software ANSYS 14.0 and discovered the rules in the transmission of heat in body tissues during moxibustion,and the features in moxibustion heat transmission (from the proximal to the distant) and heat penetration (from the surface to the internal).This study provides theoretical and experimental support for the application of moxibustion in clinical practice.
