ABSTRACT
@#Abstract: Schistosomiasis is a serious major parasitic disease that threatens human life and health. A better understanding of the mechanism of host-schistosome interactions is the key to designing new prevention and control strategies. MicroRNAs (miRNAs) are endogenous small non-coding RNA molecules, which lead to the degradation of the target messenger RNA (mRNA) or inhibition of its translation in a sequence-specific manner. Both schistosome and its host produce miRNAs, which can be secreted by extracellular vesicles (EVs). There is accumulating evidence that miRNAs from schistosome can be taken up by host cells, and finely manipulate the phenotype of host cells for their survival or pathogenesis in a cross-species manner, even inhibiting the growth and metastases of hepatoma cells. It is still unknown whether host free miRNAs can be taken up by schistosome, but this phenomenon is highly probable. miRNA-mediated cross-species regulation has emerged as a novel mechanism for host-schistosome interactions, and this review summarizes the advances in this regard.
ABSTRACT
<p><b>OBJECTIVE</b>To estimate the effects of the treatment of 360 degrees fixation of lumbar spine.</p><p><b>METHODS</b>Twenty-five cases were operated to 360 degrees fixation of lumbar spine from May 2002 to May 2005. There were 11 male and 14 female, the age ranging from 45 to 67 years, mean 56, including 16 cases of spondylolysis, 7 cases of lumbar spinal instability and 2 cases of degenerative disc undergone with anterior laparoscopic lumbar interbody fusion with syncage and autograft and posterior decompression with facet fixation. The chief complains were low back pain and radiating to lag. Fourteen cases were fused at L(4), 5 and 11 cases at L(5)-S(1). The Oswestry Disability Index (ODI) were recorded to evaluate the function at pro-operation, the second week, the third, sixth and twelfth month post-operation. The X-ray was taken to observe the fusion and the sinking cage.</p><p><b>RESULTS</b>The time intro-operation was from 110 to 180 minutes, mean 120 minutes. There was one complication in 1 case by the main vein injury. All of the 25 cases were followed-up post-operation from 12 to 35 months, mean 22.3 months. The ODI was found prominent difference compared with pro-operation in 2 weeks, 3, 6 and 12 months post-operation (P < 0.05). Twenty-five cases were fused in the third month. Two cases sank 1 mm in the third month images but solid fusion. No cage displacement was found. No retrograde ejaculation happened.</p><p><b>CONCLUSIONS</b>360 degrees fixation of lumbar spine adapts to deal with lumbar instability, degenerative disc disease and I, II degree spondylolysis. It shows less bleeding and injury, but during exposure and traction the main vessels should be very careful.</p>

@#ObjectiveTo investigate the clinical efficacy and safety of Tetramethylpyrazine and Buthus martensi on children with cerebral daminfication syndrome.Methods39 cases with cerebral daminfication syndrome were randomly divided into the study group (18 cases, treated with Tetramethylpyrazine and Buthus martensi) and control group (21 cases, treated only with general nerve nutrition therapy). The curative effect of two groups was evaluated.ResultsAfter treatment, in the study group, 11 cases were cured, 4 cases more effective, 1 case efficacy, 2 cases inefficacy; in the control group, the numbers were 6 cases, 9 cases, 3 cases and 3 cases respectively. There was a significant difference between two groups (P<0.05). There was not side effect in all cases.ConclusionTetramethylpyrazine and Buthus martensi is safe and effective to treat children with cerebral daminfication syndrome.
ABSTRACT
To promote bilingual teaching reform and explore a proper bilingual teaching mode in China,we studied the bilingual teaching of the course “Biochemistry on special subjects”.The present paper mainly designs and discusses the object of the course,teaching materials,contents and methods as well as the building of feedback and evaluation system of the course.
