2.Expression of retinoid receptors in ovarian cancer
Journal of Medical Postgraduates 2003;0(06):-
Ovarian cancer is highly lethal despite multiple therapies, and new therapies are therefore needed.Retinoids are potential anticancer drugs that can promote apoptosis,inhibit growth and induce differentiation in cancer cells,and all these functions are regulated by the expression of retinoid receptors.Herein the recent researches on the expression of retinoid receptors in ovarian cancer are reviewed.

4.Severe pneumonia complicated with heart failure in children
Chinese Pediatric Emergency Medicine 2017;24(3):166-170
It is still controversial whether or not the severe pneumonia is associated with heart failure in children.Currently,we pay more attention to the pathophysiological procedure of heart failure,such as pneumonia complicated with respiratory failure,shock and myocardial injury.Pay attention to the cardiopulmonary interaction mechanism and systemic inflammatory response.According to different pathophysiological mechanisms,guide the treatment by monitoring the hemodynamic status.
5.The effect of microRNA-204 on autophagy in U251
Practical Oncology Journal 2016;30(1):23-27
Objective To investigate the effect of microRNA-204(miR-204)on autophagy in U251. Methods Inhibition of miR-204 in U251 cell lines was done by transfection of miR-204 inhibitor(AMO-204) .Cell viability was detected by MTT assay.The autophagy of U251 was tested by immunofluorescence tech-nique.The protein level of Beclin 1,LC3 and Bcl-2 was detected by Western blot.Results Cell viability was markedly increased after inhibition of miR-204 in U251 cells.The number of autophagosome was decreased.The levels of Beclin 1 and LC3 were decreased,the protein level of Bcl-2 was significant increased by transfection of AMO-204 in U251 cells(P<0.05).Conclusion MiR-204 might at least in part promote glioma via inhibi-ton autophagy,indicating that miR-204 might be a potential target for the treatment of glioma.
6.Clinical Application of Restoring of Short Coronal Cracked Molar with Cutting Titanium Inlay Crown
Tianjin Medical Journal 2014;(5):493-494
Objective To estimate the clinical effect of cutting titanium inlay crown in the restoration of short cracked molar. Methods Sixty-four short coronal cracked teeth were randomly divided into group A and group B. Group A were treated by crown. Group B were treated by titanium inlay crown. The curative effect was evaluated every year and lasted 2 years. Results One year after the repair, there was no significant difference in the achievement ratio between two groups (93.8%vs 100%,χ2=2.064, P>0.05). Two years after the repair, the success rate was significantly higher in group B (96.9%) than that of group A (68.8%,χ2=8.892, P<0.01). The failed cases of group A were treated by cutting titanium inlay crown, showing good retention. Conclusion The retention of a short cracked molar can be improved by means of cutting titanium inlay crowns.
