Methods： 120 specimens from ESCC and 36 specimens from TIM were made into tissue chips. The presence and the levels of expression of hspl0, hsp27, hsp60, hsp70 and hsp90a were observed on tissue chips by immunohistochemistry EnVision^TM. Their correlations to clinicopathologic features were analyzed. Results： The positive staining rates of hsp10, hsp27, hsp60, hsp70 and hsp90a in ESCC and TIM were 53.8% and 37.5%, 62.0% and 42.1%, 92.7% and 63.2%, 57.9% and 22.2%, 33.7% and 18.5% respectively. There were no statistical significances between the differential expressions of hsp10, hsp27 and hsp90a in ESCC and TIM （P 〉 0.05）, but there were great statistical significances about hsp60 and hsp70 （P 〈 0.01）. The level of hsp27 declined with the lower grade of differentiation of ESCC （P 〈 0.05）. Except for hsp27, the positive expressions of the other four HSPs had no correlation to the clinicopathologic features of ESCC. Conclusion： The expressions of hsp10, hsp27, hsp60, hsp70 and hsp90a in ESCC and TIM were a common event. The levels of hsp60 and hsp70 in ESCC were higher than those in TIM. The level of hsp27 declined with the lower grade of differentiation of ESCC showed that it may be play a role in the differentiation of ESCC.展开更多

METHODS: Fifty male rats were devided into a blank group (A), a sham operation group (B), a model group (C), a scraping group (D), and a drug group (E). The rats in the group B were treated with sham operation, and groups C, D and E were made into the LDH model by operation. After operation group C were treated with no interventions, D were given scraping and E were fed with azathioprine Then the IL-1 levels of different groups were detected by enzyme-linked immuno sorbent assay method. And the transplanted coccygeal vertebra discs were observed by pathological section. RESULTS: The IL-1 levels in the groups C, D, and E were significantly higher than those in the groups A and B (all P<0.01), which proved the operationwas successful.The IL-1 levels in the groups D and E at different periods had statistical significance (F= 414.158, P<0.01). The treatment periods and interventions have interation (F=46.613, P<0.01). Multiple comparison results showed that the IL-1 levels in the groups D and E was significantly lower than that in the group C (P<0.01), while the IL-1 levels between the groups D and E had no statistical significance (P>0.05). Moreover, pathological section indicated that immuno-inflammatory response was hardly found in coccygeal vertebra discs in the groups A and B, while local immuno-inflammatory responses of the groups D and E were much lighter than that of the group C. CONCLUSION: Scraping therapy could inhibit the immuno-inflammatory responses in the rats with LDH caused by transplantation of autologous nu cleus pulposus.展开更多
