RESUMO
OBJECTIVE@#To investigate the clinical effect of arthroscopic assisted TightRope plate, Triple-Endobutton plate and Double Endobutton plate in treating of Rockwood type Ⅲ-Ⅴ acromioclavicular dislocation.@*METHODS@#From January 2014 to January 2018, 128 patients with acromioclavicular dislocation were treated by operation. According to the operation plan, the patients were divided into three groups:Double Endobutton group, Triple-Endobutton group and TightRope group. All patients with acromioclavicular dislocation were operated by the same operation team, and the chief surgeon was the same chief physician. General baseline data such as gender, age, operation time, incision length, intraoperative blood loss, VAS score of pain and Constant-Murley shoulder function score were recorded.@*RESULTS@#The wound healed well and no recent complications occurred. One hundred and eleven patients were followed up for 6 to 12(9.1±3.1) months. There was no significant difference on general data among three groups (P >0.05). Among three groups, the operation time of Triple -Endobutton group was the longest, significantly higher than that of other two groups(<0.05);the operation time of TightRope group was the shortest, significantly lower than that of other two groups (<0.05). At 1 month after operation, VAS score comparison of three groups, TightRope group was significantly lower than other two groups, with statistical difference (<0.05). At 12 months after operation of three groups, the Constant-Murley score of TightRope group was significantly higher than that of two group (<0.05). The incidence of incision infectionin TightRope group was significantly lower than that of other two groups(<0.05); the incidence of reduction loss in Double Endobton group was significantly higher than that of other two groups(<0.05), the incidence of reduction loss in TightRope group was significantly higher than that of Triple endobton group(<0.05);the incidence of joint adhesion in TightRope group was significantly lower than that of other two groups(<0.05).@*CONCLUSION@#TightRope plate fixation with arthroscopy is more advantageous than Double Endobutton plate fixation and Triple-Endobutton plate fixation.

<p><b>AIM AND METHODS</b>The method of labeled streptavidin biotin was used to study the expression of c-fos in various functional state of rat ovaries and its relationship with the levels of serum estradiol and progesterone.</p><p><b>RESULTS</b>(1) In the mature rat, c-fos expression was found higher in interstitial gland and stroma of proestrous ovaries and lower in estrous ovaries, and was found higher in luteal cells and stroma of pregnant ovaries and lower in diestrous ovaries. There was a positive correlation between the area and optical density of c-fos expression and the levels of serum E2 and P. (2) In the immature rats, c-fos expression was not found in the ovaries containing preantral follicles from DES-treated rats,and was found both in interstitial gland and stroma of the ovaries containing preovulatory follicles from PMSG-treated rats ,and the expression was higher in day 4 luteinized ovaries and lower in day 9 luteinized ovaries from PMSG with hCG treated rats. There also was a positive correlation between the area and optical density of c-fos expression and the levels of serum E2 and P.</p><p><b>CONCLUSION</b>The results suggested in rat ovaries and might play an important role in follicles development, ovulation, luteum formation and regression.</p>
