Objective To explore the significance of signal and volume change from magnetic resonance imaging (MRI) of hysteromyoma before and after uterine artery embolization (UAE) in the therapy evaluation. Methods MRI was performed in 30 patients (50 hysteromyoma) before and 3,6 and 12 months after UAE. They were grouped by location, signal and size. The MRI signal changes and the hysteromyoma's volume reduction ratio were measured. Results After 3,6,12 months, MRI of hysteromyoma was changed significantly, and all hysteromyomas had lower T2WI signals than before, some of which had higher T1WI signals. Hysteromyoma's volumes were progressively reduced, the majority of which shrinked significantly within 3 months. Evaluated by 12 month's volume changes, significant volume reduction was found in submucous fibroids, and significant difference was showed compared with intramural fibroids and subserosal fibroids (88.9 % vs. 73.7 % and 68.3 %, P=0.036, P=0.019), meanwhile,the latter two had no significant difference (P=0.384). The volume reduction rate in rich cell fibroids was higher than those in ordinary no degeneration fibroids and degeneration type, and there were significant differences (85.7 % vs. 72.1 % and 63.4%, P=0.038, P=0.014). Besides, the latter two had no significant difference (P=0.364). Large fibroids shrinked more obviously than small ones with significant difference (75.2 % vs. 59.6 %, χ2=4.563, P=0.044). Conclusion MRI is useful for the evaluation of efficacy in hysteromyoma before and after UAE, which can provide the better interventional treatment for the patients in regard to different sensitivity of hysteromyoma to UAE.

OBJECTIVE: To investigate the expression of caspase-3 during skin wound healing and explore the applicability of caspase-3 to determination of wound age. METHODS: The expression of caspase-3 were performed on 33 mice skin incised wounds at different posttraumatic intervals and 3 mice as control by immunohistochemical technique. RESULTS: Expression of caspase-3 was detectable in polymorphonuclear cells (PMNs) in the wound specimens aged 6 h. In the wound specimens aged from 12 h to 24 h after injury, caspase-3 was identified in a large number of infiltrating PMNs and part of mononuclear cells (MNCs). Afterwards, the MNCs and fibroblastic cells (FBCs) accounted in the most part of the caspase-3 positive cells. Morphometrically, the ratio of the number of the caspase-3 stained PMNs, MNCs and FBCs to total number of the cells in the wounds was evaluated and calculated. The ratio of the caspase-3 positive cells was low in the wound specimens aged from 0 h to 3 h (4.53 +/- 6.53)%, and maximized in the wound specimens aged 3 day (62.66 +/- 4.84)%. Thereafter, the ratio decreased and minimized in the specimens aged 14 day (21.56 +/- 4.54)%. CONCLUSION The results suggest that caspase-3 may play an important role in inducing neutrophil, macrophage and fibroblast apoptosis during skin wound healing. Furthermore, caspase-3 may be used as a marker for the wound age determination.

OBJECTIVE: To study the percentages of polymorphonuclear leukocytes (PMN), mononuclear cells (MNC) and fibroblastic cells (FBC) in different post-traumatic intervals after skeletal muscle mechanical injury in rats. METHODS: The rat model of skeletal muscle mechanical injury was established. The rats were divided into injured groups (6 h, 12 h, 1 d, 3 d, 7 d, 10 d and 14 d after injury) and control group. The percentages of PMN, MNC and FBC in different post-traumatic intervals after skeletal muscle mechanical injury were assessed with HE staining and image analysis. RESULTS: At post-injury 6-12h, the percentages of PMN and MNC infiltration appeared in injured sites and that of PMN reached peak. At 1 d, the percentage of MNC infiltration appeared and reached peak, while that of PMN decreased. At 3-7 d, the percentage of FBC gradually increased, while that of PMN and MNC decreased. At 10-14d, the percentage of FBC reached peak. CONCLUSION The percentages of PMN, MNC and FBC in injured zones showed time-dependent changes, which might be used as reference index for determination of age of skeletal muscle injury.
