Objective:To explore the dose-effect on ablation of human uterine myoma with HIFU scanning and find a suitable exposure parameters for HIFU ablation of uterine myoma in vitro.Methods:An extracorporeal HIFU transducer with a frequency of 0.8 MHz,intensity 0～8587.6W/cm 2 and focal length of 117mm was used.Thirty-one human uterine myoma specimens were sonicated by ultrasound with different intensity and exposure time.The threshold time and lesion size were determined and the energy efficiency factor was calculated.Results:It was found that under the same intensity,the lesion size increased with exposure time,while the threshold time decreased with the intensity.The energy efficiency factor was related to intensity and exposure time,and it was optimal under the threshold time (45s) when focal intensity was 5762.7W/cm 2.Conclusion:While using the scanning line of 15mm,the suitable exposure parameters for HIFU ablation of uterine myoma was 45 seconds for scanning lesion with focal intensity of 5762.7W/cm 2

Objective:To evaluate the role of the retinoic acid raceptor α (RARα) , retinoic acid receptor β(RARp) , estrogen receptor(ER) and progesterone receptor(PR) in the clinical pathological stage, histologcal classification and the muscular invasive depth of the endometrial carcinoma through detecting the expression of these receptors.Methods:48 paraffin sections with endometrial carcinoma by pathological conformation ware selected.Immunohistochemistry was used to detect the expression of RARα, RARβ, ER and PR.The relationship between these raceptors and the clinical pathological parameters was evaluated.Results:①The positive expression ratio of the RARα and RARβ were 47.92% (23/48) and 25.00% (12/48) respectively.The level of RARα was higher than that of RARβ (P<0.05).②The expression of RARα in the endometrial carcinoma increased with the increasing of the pathological stage and the decreasing of the histological differentiation (P<0.05).But the expression of these two receptors had no significant relation with the histological classification and the muscular invasive depth (P >0.05).③The level of the RARβ was consistent with that of the ER and PR, and it decreased with the increasing of the malignant extent of the endometrial adenocarcinoma (P < 0.05) ,and had no significant relation with the pathological stage, the histological classification and the muscular invasive depth (P >0.05).④The expression of RARβ was positively correla ted to the expression of ER and PR, but the expression of RARα was negatively correlated to the expression ER and PR.Conclusions :There is expression of RARα、RARβ in endometrial carcinoma, and it has close relationship between the expression of RARα and the development of endometrial carcinoma.The absence of the RARβ expression and the high expression of the RARα are related to the histological classification of endometrial carcinoma.

The cephalic dystocia education is an important part of obstetric education. According to current educational environment, the teaching method of multimedia combined with problem-based learning is conducive to resolving the dilemma of dystocia education. Dystocia education is designed to follow the cases as the main line and the problem as a guide, with the full integration of theory and practice. This teaching model has been recognized by the majority of foreign students, and it is worth recommending.
