Objective:Through the design mode of Radiology and radiation protection information platform, reflects the importance of radiology information platform for public service, improve the construction speed of the practical application of horizontal, the implementation of training system and supporting platform for the construction of the subject librarian personnel. Methods:The shortcoming of the information platform, puts forward the design scheme of application of accelerating the construction of information platform and corresponding countermeasures. Results:The train subject librarians and the practical application for strong information platform, give full play to their respective functions, to ensure the nuclear emergency radiation well is very necessary. Conclusion: The construct of Radiological Medicine and protection information platform of scientific integrity, effectively play the subject librarian system, is an important guarantee to improve the nuclear accident emergency response mechanism.

Objective To investigate the clinical effects of Xuebijing injection on immune function of patients with acute exacer-bation of chronic obstructive pulmonary disease(AECOPD) .Methods 103 patients with AECOPD were divided into 3 groups ,in-cluding control group(33 cases) ,the treatment group 1(36 cases) and treatment group 2(34 cases) .The conventional treatments of COPD including anti-infection ,relieving cough ,expectorant ,antispasmodic ,anti-asthmatic and aerosol therapy were adopted in all patients ,based on the similar conventional therapy in the control group ,50 mL Xuebijing injection with NS 250 mL(1/d ,course of 7 d) were added in the treatment group 1 ,and 100 mL Xuebijing injection with NS 250 mL (1/d ,course of 7 d)were added in the treatment group 2 .Serum CD3 ,CD4 ,CD8 ,CD4/CD8 and IgA ,IgG ,IgM were tested before treatment as well as 4 days and 8 days after treatment .The condition changes in all patients were evaluated .Results After 8 days of treatment ,the total treatment effi-ciency and serum CD3 ,CD4 ,CD4/CD8 ,IgA were significantly changed in the two treatment groups compared with the control group(P<0 .05) ,but serum CD8 ,IgG ,IgM showed no significant difference(P>0 .05);After 4 days of treatment ,the total efficien-cy and serum CD4 ,CD4/CD8 were significantly changed in the treatment group 2 which injection dose was increased compared with the control group(P<0 .05) .The total treatment efficiency and immune function showed no significant difference between the two treatment groups(P>0 .05) .Conclusion Xuebijing injection can improve the immune function and treatment efficiency of AECO-PD patients .Appropriately increase the dose can achieve better clinical results in a short period .In conclusion ,Xuebijing injection is a feasible and effective method for the clinical treatment of AECOPD .

Genetic polymorphisms are thought to be associated with the individual difference in the esophageal cancer treatment.A large number of evidences show that 5-FU and cisplatin metabolism,apoptosis and angiogenesis related gene SNPs are associated with the therapeutic sensitivity of esophageal cancer.

With depth understanding of the mechanism of human leukocyte antigen G (HLA-G) protein,more and more studies have found that HLA-G is closely related with tumor immune escape.Numerous studies have shown that the expression of HLA-G protein and mRNA could be detected in patients with cancer.

Objective To detect the expressions of microRNA-126 (miR-126) and microRNA-7 (miR-7) in esophageal squamous cell carcinoma (ESCC) and to analyze their correlations with clinicopathologic features and prognosis of ESCC.Methods The expressions of miR-126 and miR-7 in 116 ESCC samples and matched normal tissue samples were detected by real-time PCR.Statistical analysis was used to find the relationships among the expressions of miR-126 and miR-7,pathological characteristics and prognosis.Results Low expression,normal expression and high expression of miR-126 were found in 73 (62.9％),35 (30.2％) and 8 (6.9％) carcinoma samples respectively.Low expression,normal expression and high expression of miR-7 were found in 52 (44.8％),35 (30.2％) and 29 (25.0％) carcinoma samples respectively.The disease-free survival in patients with low expression of miR-126 and miR-7 was shorter than that in patients with non-low expression (x2 =4.268,P ＜0.05 ; x2 =4.993,P ＜0.05).The low expression of miR-126 was correlated with tumor location,family history and drinking (x2 =14.564,P ＜ 0.05 ; x2 =5.691,P ＜ 0.05 ; x2 =4.971,P ＜ 0.05),but was uncorrelated with gender,age,diferentiation,infiltration,lymphatic metastasis and smoking (all P ＞ 0.05).The low expression of miR-7 was uncorrelated with pathological characteristics of ESCC (all P ＞ 0.05).Conclusion The low expressions of miR-126 and miR-7 may be related to the prognosis of patients with ESCC,and have a certain clinical detection significance.

miRNAs are endogenous short RNA molecules widely distributed in eukaryotic organisms.They are closely related to tumor development. One good example is miR-21. It is overexpressed in a variety of tumor tissues, suggesting that miR-21 may have significant carcinogenic activities and act as a oncogene.Many studies confirm that overexpression of miR-21 has great indication in the development, diagnosis, biological treatment and prognosis of gastrointestinal cancer.

hMSH6 is one of the most important members in the mismatch repair family. Its polymorphism is closely related to the pathogenesis and development of neoplasm, particularly in colorectal cancer and endometrial cancer. Moreover, it has been suggested to play a more important role in endometrial cancer compared with hMLH1 and hMSH2.

Variants of gene loci on susceptibility genes are the major individual susceptibility factors of esophageal squamous cell carcinoma (ESCC) in China.Some of the gene loci participate in the DNA damage and repair,and some are related with cancer suppressor genes,metabolism enzymes,trace elements and smoking.The single nucleotide polymorphisms of these susceptibility genes are closely correlated with the genesis of ESCC.
