? AlM: To investigate the therapeutic effects of Pranoprofen on tear dynamic abnormity induced by conjunctivochalasis ( CCh) .
?METHODS: Seventy cases ( 70 eyes ) whose the main symptoms was epiphora induced by CCh were divided into II, Ⅲ and Ⅳ in 3 groups according to Zhang’s grading standards, meanwhile, all the patients were treated with the eye drops of Pranoprofen for 2wk. After that, the curative effect of each group was analyzed before and after treatments according to the symptoms, dye disappearance test, bitter taste test and tear break-up time.
?RESULTS: After 2wk treatment of Pranoprofen, the symptom of patients at grade I and II improved obviously grade Ⅲ improved more, grade Ⅳ did little. The positive rate of dye disappearance was the highest in grade II, the second in grade Ⅲ, and the third in gradeⅣ. There was significant difference among the 3 groups (P<0. 05). The time of bitter taste test was shortened (P<0. 05) and the tear break-up time was prolonged (P<0. 05) in grade II after treatment, however, the time of those in gradeⅢandⅣhad not changed than before ( P>0. 05).
?CONCLUSlON: Pranoprofen has good effects on tear dynamic abnormity induced by grade II of cch.

Objective　To investigate the effect of T-2 toxin on apoptosis of chondrocytes.Methods　Chondrocytes which were obtained from aborted fetal were cultured in vitro.Four days later,these chondrocytes were exposed to T-2 toxin in different concetrations for 16 hours.According to the concentratio ns,five experimental groups were divided:0,5,10,20,40 μg/L.Then TUNEL staining and Flowcytometry were used to detect the apoptosis of chondrocytes qualitativel y and quantitatively,the effect of T-2 toxin on proliferation of chondrocytes were also observed.Results　After being exposed to T-2 toxin,the body of chondrocytes shrinked obviously and there was a dose-dependent relationship bet ween the toxin concentration and the degree of shrink.The concentration of T-2 toxin changed from 0 μg/L to 10 ng/ml,the number of apoptosis increased.Conclusions　 T-2 toxin can inhibit the proliferation of chondroyte significantly in a dose-depenent manner. T-2 toxin can induce the apoptosis of chondrocyte and the numbers of apoptosis is proportionate to the concentration of T-2 toxin in particular range.

How to remove the well fixed cement or cementless prosthesis and get a completely distal cement removal in the rTHR are critical to the outcome of revision. Because of higher rate of union, excellent intraoperative exposure, and adjustment of abductor tension, ETO has been widely applied to rTHR and complicated primary THR by foreign scholars. Furthermore, this technology has wide indications, very few contraindications, high cure rates,and low complications rate. ETO turns out to be a safe and effective revision technology. In the article, the indication, contraindication, complications and advantages of this technique were reviewed.
