Objective To investigate the potential infectious of the new-Bunyavirus among the blood-donors in Guiyang area.Methods A total of 1 187 blood samples and the basic data were collected from the blood center of Guizhou.The new-Bunyavirus total antibody in serum was tested by enzyme-linked immunosorbent assay(ELISA).The samples were tested repeatedly by ELSIA,and general statistics description of the samples′ data was did by Excel2007,and the age,gender,occupation and collecting time of the samples were analyzed by SPSS19.0.Results The positive rate of new-Bunyavirus total antibody among blood-donors in Guiyang was 5.31%,and the new-Bunyavirus total antibody titers was 1∶20-1∶64.The positive were tested by PCR for identifying,PCR results of all positive samples were negative.The positive rates between different genders,ages,occupations,and nationalities were not statistically significant(P>0.05),but the difference of positive rates between epidemic period and later stages of the epidemic was statistically significant(χ2=4.623,P=0.032).Conclusion There are new-Bunyavirus total antibody positive samples in blood-donors,noticing that there is a possibility of potential infection among Guiyang blood-donors and even healthy people.

OBJECTIVETo evaluate the efficacy and safety of testosterone undecanoate (TU) in the treatment of late-onset hypogonadism (LOH) by meta-analysis.

METHODSWe searched Pubmed (until April 1, 2014), Embase (until March 28, 2014), Cochrane Library (until April 17, 2014), CBM (from January 1, 2001 to February 2, 2014), CNKI (from January 1, 2001 to February 2, 2014), Wanfang Database (from January 1, 2000 to February 2, 2014), and VIP Database (from January 1, 2000 to Febru ary 2, 2014) for randomized controlled trials of TU for the treatment of LOH. We evaluated the quality of the identified literature and performed meta-analysis on the included studies using the Rveman5. 2 software.

RESULTSTotally, 14 studies were included after screening, which involved 1 686 cases. Compared with the placebo and blank control groups, TU treatment significantly increased the levels of serum total testosterone (SMD = 6.22, 95% CI 3.99 to 8.45, P < 0.05) and serum free testosterone (SMD = 4.35, 95% CI 1.86 to 6. 85, P < 0.05) but decreased the contents of luteinizing hormone (WMD = -2.23, 95% CI -4.03 to -0.42, P < 0.05), sex hormone binding globulin (WMD = 2.00, 95% CI 1.38 to 2.63, P < 0.05). TU also remarkably reduced the scores of Partial Androgen Deficiency of the Aging Males (WMD = -9.49, 95% CI -12.96 to -6.03, P < 0.05) and Aging Males Symptoms rating scale (WMD = -2.76, 95% CI -4.85 to -0.66, P <0.05) but increased the hemoglobin level (SMD = 2.35, 95% CI 0.29 to 4.41, P < 0.05) and packed-cell volume (SMD = 4.35, 95% CI 1.36 to 7.33, P < 0.05). However, no significant changes were shown in aspertate aminotransferase, alanine transaminase, prostate-specific antigen, or prostate volume after TU treatment (P > 0.05).

CONCLUSIONTU could significantly increase the serum testosterone level and improve the clinical symptoms of LOH patients without inducing serious adverse reactions. However, due to the limited number and relatively low quality of the included studies, the above conclusion could be cautiously applied to clinical practice.

Objective To investigate the anti-inflammatory/immune modulatory effects of high-expressing membrane bound M-CSF-hematopoietic malignant cells on macrophages. Methods After coculturing RAW264.7 and murine macrophage cell line with Namalwa-M, a cell line stably expressing mM-CSF, and companing with Nainalwa-V, a cell line stably transfected with the empty vector as the control, flow cytometry was used to detect the expression of the marker of alternatively activated macrophages, CD206, and intracellular expression of IL-10, IL-12, IL-6 and TNF-α to study the immunophenotype of RAW264.7; phagocytic assays to investigate their functional activity in vitro. Results RAW264.7 cocultured with Namalwa-M consistently showed high-level expression of CD206, which indicated activities of these macrophage cells were increased. Furthermore, these RAW264.7 expressing high levels of IL-10, TNF-a and low levels of IL-12, IL-6, as determined by intracellular staining were suggested that the phagocytic activity was increased. Functionally, RAW264.7 cocultured with Namalwa-M showed a higher level of phagocytic activity. Conclusion Macrophage generated in vitro after cocultured with mM-CSF-expressing hematopoietic malignant cell line could be transformed into abnormal macrophage with an immunophenotype defined as IL-10-high, IL-12-low, IL-6-low and TNF-α-high.

Objective To explore the changes of high-sensitivity C reactive protein(hs-CRP) and platelet parameter levels in newborns with hypoxic-ischemic encephalopathy(HIE)and its clinical significance.Methods Thirty-five infants with HIE and 16 healthy newborns were selected as study cases and controls respectively by automantc biochemistry analyzer.Serum hs-CRP content was measured by reaction rate method;Platelet parameter levels were detected by collecting blood samples from peripheral vascular of heel,and the activity of creatine kinase(CK),creatine phosphokinase isoenzyme(CK-MB),lactate dehydrogenase(LDH),alpha-hydroxybntyric dehydrogenase(?-HBDH),alanine transaminase(ALT),aspartate aminotransferase(AST) were assayed as well.Results 1.The hs-CRP levels in newborns with HIE increased obviously in acute stage,and significant difference were observed compared with controls(P0.05).2.PLT in newborns with HIE decreased significantly in acute stage compared with that of controls(P0.05).3.The values of CK,CK-MB,LDH,?-HBDH,AST,ALT in newborns with HIE were significantly higher than those in controls in acute stage(P

OBJECTIVETo investigate three-dimensional kinematics of the superficial and deep portion of triangular fibrocartilage complex (TFCC) in different parts of the forearm rotation.

METHODSSix wrists of 6 volunteers were used to obtain CT scans at different positions of the wrist. The wrists were scanned from 90 degrees of pronation to 90 degrees of supination at an interval of 30 degrees. The 3-dimensional radius and ulna were reconstructed with customized software and changes in length of the superficial and deep portion of TFCC during forearm rotation.

RESULTSIn forearm pronation, the superficial dorsal portion and the deep palmar portion of the TFCC were tight. While the superficial palmar portion and the deep dorsal potion of the TFCC were lax. In supination, the changes in length of all these fibers were reverse.

CONCLUSIONSIn forearm rotation one portion fibers of dorsal TFCC and one portion fibers of palmar TFCC are tight, and this mechanism controls stability during DRUJ rotation.

Objective To investigate the advantages of detection for EGFR gene mutations by denaturing high performance liquid chromatography (DHPLC) technology. Methods DHPLC was used to detect EGFR gene mutations at exon 19 and 21 in 49 cases of non-small cell lung cancer (NSCLC) patients,and the direct DNA sequencing was used to verify the accuracy of DHPLC detection. Results EGFR gene mutation was identified from 13 of 49 cases by DHPLC,including deletion mutation at exon 19 in 10 cases (76.92 %) and alternative mutations at exon 21 in 3 cases (23.08 %). Mutation results of DHPLC was consistent with DNA direct sequencing. The results of the direct DNA sequencing were the same as those of DHPLC. The sensitivity of mutation test by DHPLC was 100 %. Conclusion DHPLC technology can be used for large scale screening of EGFR gene mutation with rapid and accuracy.

OBJECTIVETo observe the clinical efficacy of Tiaozhi Jiangtang Tablet (TZJT) on patients suffering from diabetes mellitus with blood stasis syndrome.

METHODSSixty patients were randomly assigned into 2 groups, the TZJT group (n = 30) treated with TZJT tablet and asprin, the control group (n = 30) treated with asprin alone.

RESULTSThe improvement of symptoms was more significant in the TZJT group than that in the control group (P < 0.05). Levels of serum endothelin (ET), nitric oxide (NO) content and blood viscosity were decreased in both groups after treatment, and the effect of TZJT plus asprin was superior to that of asprin alone.

CONCLUSIONTZJT combined with asprin is effective in improving the serum content of ET and NO and reducing blood viscosity.
