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.

Objective To explore the effects of recombinant human hormone(rhGH) on the plasma total protein,plasma albmin,healing of Wound surfaces in patients with the second degree burns wound.Methods 38 pa- tients with the second degree burns wound were divided into treatment group and control group randomly.All the patients were subject general.19 patients in the treatment group were given rhGH in a dose of 0.2U/kg for 14 days beginning from postoperative 5 days.The plasma total protein concentration,plasma albumin concentration,healing rat of wound surface and scar of patients of the two group were compared.Results The plasma total protein concen- tration plasma albumin concentration of the treatment group were significantly in creased,the scar hyperplasia of the treatment group were significantly mitigated and the healing time of wound surfaces of the treatment group were sig- nificantly shortened.Conclusion rhGH is found to promote protein anabotism and shorten the healing time of wound surfaces and mitigate the scar hyperplasia patients with the second degree burns wound.

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 investigate the risk factors of hyperuricemia among residents aged >/= 20 years.

METHODSA community based case-control study was conducted in 286 patients with 858 controls without hyperuricemia. Available data were analyzed by mono-factorial and multi-factorial logistic regression methods using SPSS 10.0 software.

RESULTS17 factors related to exposure were identified for hyperuricemia the mono-factorial analysis when; five factors were selected through multiple factoral logistic regression model at P = 0.05 level. The risk factors on hyperuricemia were: hypertriglyceridemia (OR = 3.069), alcohol consumption (OR = 2.032), obesity (OR = 1.802), taste of spicy food (OR = 1.877) and hyperglycemia (OR = 1.622).

CONCLUSIONHyperuricemia is a disease associated with environment and style-life. Changing lifestyle, such as decreasing alcohol consumption and adopting proper structure of diet may prevent or decrease the chance of getting hyperuricemia and gout.
