Objective To assess the clinical application values of the protcin markers associated with Down syndrome (DS) in maternal serum which were screened and identified.Methods Seven maternal serum samples with DS fetus ( DS group) and 7 maternal serum samples with normal fetus ( control group) in the second trimester were separated by two-dimensional gel electrophoresis (2-DE).The differentinal expression profile of proteome in maternal serum from DS group was established.The differentially expressed proteins were screened by mass spectrometry (MS) and some proteins were verified by Western blotting (WB).Results Twenty-nine proteins were discovered to be differentially expressed by more than 1.5 folds in maternal serum from DS group,among which 19 proteins were up-regulated and 10 proteins were downregulated.Eight proteins displayed 2 or more folds changes in maternal serum from DS group were identified by MS and possibly matched with 12 proteins in Ameracan National Center of Biotchnology Information (NCBI) protein sequence database,such as dGTPase and Beta2-Glycoprotein Ⅰ (β2-GPI),etc.The resuhs of WB showed that the mean a values of dGTPase and β2-GPI were 21 567.0 ± 3009.4 and 22 097.0 ±3958.9 in the DS group,3957.7 ± 250.9 and 1799.7 ± 105.5 in the control group respectively,which presented that the expression of dGTPase and β2-GPI significantly increased in DS group (t'dGTPase =- 17.66,t'β2-GPI =- 14.83,P ＜0.0001 ).Conclusions 2-DE and MS are effective methods for preliminary identification of protein markers associated with DS in maternal serum.dGTPase and β2-GPI verified by WB laid a solid fundation for further screening new biologic markers for early diaglosis of DS.

Mesenchymal stem cells (MSCs) not only exhibit a marked tropism for tumors,but also exert antitumorigenic activity or as an emerging vectors to express foreign genes continuously and efficiently within the tumor microenvironment,suppress tumor's growth and metastasis.Conversely,MSCs can accelerate tumor development through promoting tumor stroma remodeling and tumor vascular formation,inhibiting tumor local immune and changing tumor phenotype.The reason for this discrepancy may be attributable to different sources of MSCs,the heterogeneity of MSCs,differences in tumor microenviroment,or another factor that is not yet appreciated.

Objective:To discuss the significance of standardized treatment for cancer pain, according to the Cancer Pain Treat-ment Specification (2011 Edition) issued by the Ministry of Health, PR China. Methods:Clinical data of 126 patients with cancer pain, who were admitted to the Department of Medical Oncology, The Fourth Hospital of Hebei Medical University, were collected to com-pare the improvement of the Numeric Rating Scale (NRS) score, number of breakthrough pain, and quality of life score after treatment. The relationships between different pain grades, disease entities, and treatment effect were analyzed. The influence factors of pain relief were also analyzed by using Logistic regression analysis. Results:1). Following standardized treatment, the improvement rate of NRS score has shown significant differences in pain grading (P=0.001) and gender (P=0.000). However, no significant differences were ob-served between different diseases (P=0.112). The improvement rate of the life quality score and the number of breakthrough pain had no significant difference after standardized treatment. 2). The grading of cancer pain and the disease entities had little effect on cancer pain relief. 3). The anti-tumor treatment and“no distant metastasis”were the independent factors that brought about the decrease in NRS and quality of life scores.“No distant metastasis”(P=0.046) was the independent factor that reduced the number of pain out-breaks. Conclusion: The standardized treatment positively affects the NRS score, number of breakthrough pain, and quality of life score. Patients who received anti-neoplastic therapy and who had no distant metastasis showed significant treatment effectiveness in pain management.
