Objective To clarify the differential diagnosis between limb-girdle muscular dystrophy type 2B (LGMD2B) and polymyositis (PM). Methods Analyzed the character of clinical, histochemical and immunohistochemical pathologic with biopsied skeletal muscle in 5 patients with LGMD2B and the relationship with PM. Results Both LGMD2B and PM showed the muscle weakness in proximal limbs and elevated creatinkinase level and electromyogram showed myogenic damage. Histochemical stains: it was similar to PM, that was the muscle fibers degenerating, regenerating and necrotic and the infiltrating inflammatory cells in different extent in 5 patients. Immunohistoehemical stains: anfi-Dysferlin monoelonal antibody showed that Dysferlin was deficient on sarcolemma in LGMD2B, but it was normal in PM. Conclusions It is resemble on the clinical and histoehemieal pathologic characters in both LGMD2B and PM. It is key to antidiastole LGMD2B and PM by the immunohistochemieal stain of anti-Dysferlin monoelonal antibody.

Fetal inflammatory response syndrome is a sub-clinical state that cause fetal immune sys-tem could be activated and released large amounts of proinflammatory cytokines.Either caused by infection of factors such as chorioamnionitis,fetal sepsis or non-infectious factors such as asphyxia,chronic lack of oxy-gen,which are likely to cause neurological damage in preterm or full-term children .This article reviewed the progress on the mechanism of neonatal encephalopathy caused by fetal inflammatory response syndrome.

Epithelial-mesenchymal transition (EMT) is an important biological process in embryonic development and tumori-genesis. In this process, epithelial tumor cells can obtain mesenchymal phenotypes and promote tumor invasion and metastasis. EMT is controlled by multiple transcription factors, signal pathways, and microRNAs. EMT and cancer stem cells are closely related. EMT also promotes the self-renewal ability of tumor cells and the overexpression of EMT-related markers in tumor cells with stemness. Some mi-croRNAs can control EMT process and stemness. In this study, recent developments on EMT and cancer stem cells in tumor metastasis were summarized to provide new insights into target therapy of tumor metastasis and recurrence.

AIM:ToinvestigatetheregulationofmiR-21onFasLexpressionanditseffectonthegrowthand apoptosis in glioma cells , and to evaluate the molecular mechanism .METHODS:Differential expression levels of miR-21 in human glioma U251 cells were achieved by transfecting with miR-21 mimics, miR-21 inhibitor or scramble .The viability and apoptosis of U251 cells were detected by CCK-8 assay and flow cytometry with Annexin V-FITC/PI double staining. The recombination vector pmirGLO-FasL was constructed .Dual-luciferase reporter experiment was performed to validate the target genes of miR-21.The expression vector pcDNA3.1-FasL was also constructed , and the biological activity and regula-tory role of miR-21 in U251 cell apoptosis were analyzed by a restore experiment .RESULTS:Exogenous overexpression of miR-21 increased the viability and decreased the apoptosis of U 251 cells ( P<0.05 ) , while miR-21 inhibitors generated the opposite results (P<0.05).Dual-luciferase reporter assay and restore experiment revealed that miR-21 negatively reg-ulated the expression of FasL gene which was regarded as the target gene , thus decreasing the apoptosis of U 251 cells. CONCLUSION:miR-21 increases the viability of glioma U251 cells, in which FasL may be one of the target genes .

This experiment has proved that bolbostemmosaponin and its constituents A and D have relatively powerful spermatocidal effects. They can kill all spermatozoa in a moment at the concentrations of 0.04%, 0.04% and 0.03% respectively. These spermatocidal agents mainly distroy the biomembrane system of sperm. Using the fixed gelatin membrane technique proved that all of them can strongly inhibit tne activity of a single sperm acrosin at the concentration of 0.05%.

Taxonomy of genus Rhodococcus has been changing since it was set up by Zopf in 1891 The classification of the genus has been changed dramatically in recent years, with the species being reclassified and new species described Th e changing of taxonomy is mainly on the methods' altering from old morphological to modern polyphasic taxonomy Additionally, there has been increased interest i n rhodococcus for its abilities to degrade a range of environmental pollutants a nd to transform or synthesize compounds with possible usefull application

BACKGROUND:Fibrin glue can function to close the wound tissue, reduce leakage, stop bleeding, promote wound healing and prevent adhesion.
OBJECTIVE:To systematicaly review the application of fibrin glue in thyroid surgery.
METHODS:We searched China Journal Net database, Wanfang database, VIP database, Chinese Biomedical Database Online to retrieve clinical randomized controled trials related to fibrin glue applied in thyroid surgery from January 2000 to April 2013. Included studies were analyzed using Rev Man 5.2 statistical software for Meta-analysis.
RESULTS AND CONCLUSION:A total of six studies including 797 cases were enroled in result analysis. Meta-analysis showed that the drainage volume at postoperative day 1 and total postoperative drainage volume were higher in the fibrin glue group than the control group (without fibrin glue) [odds ratio=-27.36, 95% confidence interval (-33.86,-20.87),P < 0.00001; weighted mean difference=-38.73, 95% confidence interval (-44.78,-32.67),P < 0.000 01]. The suture removal time was shorter in the fibrin glue group than the control group [odds ratio=-2.00, 95% confidence interval (-2.17,-1.83),P < 0.000 01]. No significant difference was found in the postoperative 3-day fever incidence [odds ratio=1.53, 95% confidence interval (0.59,3.96),P=0.38], wound infection [odds ratio=0.86, 95% confidence interval (0.12, 6.15),P=0.88], and postoperative hematoma [odds ratio=0.86, 95% confidence interval (0.21, 3.48),P=0.83] between the two groups. These findings indicate that fibrin glue used in thyroid surgery can significantly reduce drainage by non-increasing postoperative complications.

Objective To investigate the change of serum C-reactive protein(CRP) levels in patients with acute cerebral infarction(ACI) and ACI with multiple organ dysfunction syndrome(MODS), and the relationship between serum CRP levels and incidence of MODS.Methods The serum CRP levels of 30 normal healthy people and 82 patients with ACI were detected by immune transmission turbidity method. The data from the patients with lacunar cerebral infarction(LCI), acute simple cerebral infarction(PACI) and ACI with MODS(ACI+MODS) were compared.Results The levels of serum CRP in patients with ACI significantly increased compared with the controls( P
