Objective Carboxypeptidase E ( CPE) is one of the most important carboxypeptidases in-volved in the biosynthesis of numerous peptide hormones and neurotransmitters and plays an important role in en -docrine regulation .A splice variant of CPE ( CPE-ΔN) has been detected and the mechanism of CPE -ΔN action in tumorigenesis has been studied in many different cancers .The aim of this study is to examine CPE -ΔN ex-pression in human colorectal cancer ( CRC) and to evaluate its possible application as a potential prognostic mark-er.Methods In the present study ,we have analyzed isoform expression of CPE -ΔN by qRT-PCR and West-ern blot in 219 CRC patients .Results Our results showed that CPE -ΔN was overexpressed in colorectal tumor tissue and that high CPE -ΔN mRNA expression was closely correlated with tumor differentiation ,pT classifica-tion,pN classification,tumor recurrence and lymph node metastasis .High CPE-ΔN expression was also identi-fied as an independent prognostic factor using a multivariate analysis (P=0.011).Conclusion Based on these results,we can conclude that CPE -ΔN expression might be a potential prognostic marker for CRC patients .

Objective To detect the TNFSF13 expression and to evaluate its possible use as a potential prognostic marker in breast cancer .Methods We analyzed TNFSF13 expression by Western blot and qRT -PCR in 93 breast cancer patients .Results Our results showed that TNFSF 13 was overexpressed in breast cancer tis-sue.High TNFSF13 mRNA expression was closely correlated with tumor differentiation , pN classification ( P=0.003,0.022).In addition,patients with high TNFSF13 expression had a significantly shorter survival analyzed by Kaplan-Meier(P=0.04,log-rank test).Cox proportional hazards regression multivariable analysis revealed that high expression of TNFSF13 was identified as an independent prognostic factor (P=0.03).Conclusion TNFSF13 expression might be a novel target for prognosis and intensive therapy in breast cancer patients .

Based on analysis of researches in China and abroad on financial burden of hospital acquired infection,the paper named key setbacks in such a study in China and advocated prospective studies in this regard.Furthermore,the authors proposed studies on the financial burden incurred by years of life lost due to such infection,and that on the burden from the hospital perspectives.On the basis of direct and indirect financial burdens,the assessment and dynamic analysis of overall financial burden were proposed,to establish a uniform evaluation method or guidance for such infection and ensure the compatibility of various research outcomes.
