1.Goals for the treatment of multiple myeloma in the era of novel agents
Chinese Journal of Clinical Oncology 2014;(13):823-826
The treatment of multiple myeloma has become possible in the era of novel agents. Novel agents have dramatically improved the response rates of multiple myeloma (MM) and have extended the survival of patients even if MM remains an incurable disease. De-termining the treatment goals of MM has become a major challenge for clinicians in the era of novel agents. Many results show the correlation between response depth and patients' survival. Complete remission (CR), stringent CR, phenotypic CR, and CRs at the molecular and PET-CT levels are being explored and becoming the goals of MM treatment. Doctors should balance efficacy with adverse effects in daily clinical practice to avoid the blind pursuit of a high and deep response rate.

Objective To study the expression of hepatocyte growth factor (HGF) in placenta from normal pregnancy and pregnancy induced hypertension (PIH) and the effect of HGF on angiogenesis in placenta. Methods Immunohistochemistry was used to determine the location and intensity of HGF staining in placenta from 20 cases of normal pregnancy and 58 cases of mild,moderate and severe PIH groups. HE staining was used in order to count the number of the vessles. Results HGF mostly were expressed in villous core mesenchymal cells,less in decidual cells . Intensity of HGF immnostaining in villous mesenchymal cells was significantly reduced in the severe PIH group compared with the normal group(H=7.395,P=0.003),while there were no statistical differences between the mild,moderate PIH group and the normal group (H=0.869,P=0.351,H=0.017,P=0.896) .The count of vessels reduced in severe PIH (F=10.676,P=0.008). There was positive correlation between the expression of HGF and the count of vessels in villous(r=0.246,P=0 030). Conclusion These results suggested that HGF is secreted mainly by villous core mesenchymal cells in human placenta and the reduction of HGF in PIH may be responsible for the impaired vascularization in PIH.

Objective: To assess trends of β-blocker use within 24h of admission in ideal candidates with acute myocardial infarction (AMI) in eastern urban China from 2001 to 2011. Method: A 2-stage random sampling design was performed. In the first stage, a simple random-sampling was used to identify participating hospitals. In the second stage, a systematic sampling was conducted in 2001, 2006 and 2011 to select cases from the participating hospitals. Data was obtained by central medical record abstraction. 10-year trend and predictors of early β-blocker application were assessed with weighted calculation for each year to represent the overall situation of eastern urban China. Results: 35 hospitals were sampled and 32 of them were finally participated. With necessary exclusion, 1399 ideal candidates were included in this analysis. The early weighted β-blocker application rates in 2001, 2006 and 2011 were 64.7%, 69.7%, and 60.9% respectively, P=0.0447 for trend. Patients with chest pain at admission (OR=2.22, 95% CI 1.19-4.13), higher systolic blood pressure (OR=1.40, 95% CI 1.11-1.77) or faster heart rate (OR=2.01, 95% CI 1.58-2.55) were more likely to use β-blocker; in contrast, compared with NSTEMI patients, STEMI patients seemed less likely to receive such treatment (OR=0.55, 95% CI 0.37-0.81). Conclusion: The early β-blocker therapy in eastern urban China is suboptimal for ideal AMI patients who could benefit from it. The application pattern has not been changed from 2001 to 2011 which might be related to physicians' misunderstanding of relevant evidence or guidelines. Our study may help to create an important target to improve the quality of AMI care.
