Expression of TGF-beta and hepatocyte growth factor in kidney tissues of children with primary focal segmental glomerular sclerosis / 中国当代儿科杂志

<p><b>OBJECTIVE</b>To study the expression of transforming growth factor-beta (TGF-beta) and hepatocyte growth factor (HGF) in kidney tissues of children with primary focal segmental glomerular sclerosis (FSGS) and the possible role of the two growth factors in the development of FSGS.</p><p><b>METHODS</b>Kidney specimens were obtained from 33 children with primary FSGS and 7 children with isolated haematuria but without FSGS (control group). Of the 33 children with primary FSGS, 6 children had no renal tubule interstitial pathological damage (Experimental I group) and 27 children had renal tubule interstitial pathological damage (Experimental II group). Expression of TGF-beta and HGF in kidney tissues was ascertained by the immunohistochemical method.</p><p><b>RESULTS</b>TGF-beta and HGF were expressed in the three groups, but there were significant differences among the three groups. The expression of TGF-beta and HGF in the two experiment groups increased significantly compared with that in the control group. The Experimental II group had increased TGF-beta expression but a significantly decreased HGF expression compared with the Experimental I group. The index of tubule interstitial pathological changes was positively correlated with the TGF-beta expression (r=0.763, P<0.01), but negatively correlated with the HGF expression (r=-0.461, P<0.05) in the Experimental II group. There was a negative correlation between TGF-beta and HGF expression in children with primary FSGS (r=-0.425, P<0.05).</p><p><b>CONCLUSIONS</b>The expression of TGF-beta and HGF in kidney tissues is increased in children with primary FSGS. TGF-beta might be a fibrogenic factor and HGF might be an anti-fibrotic factor in the kidney in primary FSGS.</p>

Investigation on training of clinical teachers in medical education / 上海第二医科大学学报

Objective To explore the contents,routes and ways of the training of clinical teachers in teaching hospitals.Methods According to the requirement of teachers' professional development,the characteristic of clinical teachers in teaching hospitals,setting from the cultivating of fundamental ability and occupation quality,to reinforce the training of clinical teachers,especially young teachers' basic teaching skills,job skills and professional ethics in order to improve the teaching team's overall quality unceasingly. Results According to the results of the classroom teaching mass and practice teaching mass' test from the year 2005 to 2007,the teaching ability and consciousness of clinical teachers were reinforced after the training. Conclusion With the dual role of doctor and teacher,the clinic teachers should be trained to reinforce their basic teaching skills and professional competence,so that they can have the ability to cultivate the high-qualified medical talent.

VOCC and BKCa mRNA expression in kidney tissues of IgA nephropathy patients / 上海第二医科大学学报

0.05). ConclusionThe expression of VOCC mRNA and BKCa mRNA in kidney tissues of IgA nephropathy patients are abnormal.There is positive correlation between the abnormal expression of VOCC mRNA and BKCa mRNA and total glomerular pathological lesions integrals.The expression of VOCC mRNA and BKCa mRNA in kidney tissues of IgA nephropathy may serve as the indictor for the disease progression.
