The azygos system was studied on 78 Chinese adult cadavers. The occurrence of the type of coexisted azygos, hemiazygos and accessory hemiazygos veins is 64.10%. The components of hemiazygos and accessory hemiazygos veins are sub- ject to such a large variation that the division of the azygos system into three major trunks is not always practicable since no generally-agreed criterion can be observed. The authors, according to Seib's suggestion! classify the azygos system into three types, that is, the double trunk, the intermediate, and the single trunk types, based on the condition of the interruptions of the hemiazygos. system Intermediate type occurs most frequently and its occurrence is 52.56% in this series.The interruptions of the hemiazygos system and the communications between azygos vein and hemiazygos system are far more numerous in Chinese than in Caucasians. The racial difference of the azygos system between Chinese and Caucasian subjects suggests that the azygos system of the Caucasians more likely belongs to the embryonic type. The middle segment of the azygos vein runs to the left of the midline in adults, and the origin of the azygos system usually connects with the inferior vena cava or the renal vein.The findings mentioned above might arouse the interest or the attention of the clinicians.

Objective To analyze the bone mineral density(BMD)and the correlated influence factors ingirls. Methods BMD and partial physical development variables of 714 girls, aged 9 to 16, were examined in Guangdong and Guangxi province and a questionnaire was administered to all subjects to determine their milk intake, physical activity, menarche, and regularity of menstruation. Results BMD in girls increased by 4.4% at age of 9～12, increased by 6.0% at age of 12～14, and increased by 2.5% at age of 14～16. Compared with girls having less than six-hour outdoor exercise, those having more than six-hour outdoor exercise revealed higher BMD levels (P200ml/day) might be effective for promoting BMD of girls during puberty.

Objective To evaluate the value of transvaginal ultrasound in the diagnosis of tubal pregnancy.Methods The retrospective analysis was made according to transvaginal ultrasound inspection on 77 patients and their sonographic appearance and ultrasonic diagnosis of tubal pregnancy proved by surgery and pathology.Results The two-dimensional sonogram mainly showed the adnexal masses and the liquid area opaca in the pelvic cavity.The masses were divided into three types:germ heart-beat type,gestational sac type,and uneven mixed mass type.According to distinctive two-dimensional sonographic appearance,the accuracy rates of transvaginal ultrasound in the diagnosis of rupture,nonrupture,and abortion tubal pregnancy were 87.23%,100%,and 34.62%,respectively.In combination with pelvic mass,indirect sign of effusion,and patient history,the accuracy rates of ultrasonic diagnosis in the above clinical classifications were 95.74%,100%,and 84.61%,respectively.The accuracy rate of the total ultrasonic diagnosis was 92.21%.Conclusions Transvaginal ultrasound has higher accuracy in the diagnosis of rupture and nonrupture tubal pregnancy,but it lacks distinctive sonographic appearance in the diagnosis of the majority of abortion tubal pregnancy,which is the main reason for affecting the accuracy of ultrasonic diagnosis of tubal pregnancy.

Objective To evaluate the characteristics of the haemodynamics of the hysteromyoma and its diagnosis value. Methods To apply the transvaginal color doppler ultrasound to detect the blood flow parameters of the uterine artery and the muscular tumor’s peripheral and inner area from 68 patients with hysteromyoma, compared with the blood flow parameters of the uterine artery from 50 normal women so as to analyze their difference. Results (1) In the hysteromyoma group, the maximum blood flow velocity during the systolic phase (SP) and the minimum blood flow velocity during the end-diastolic phase (ED) of uterine artery are significantly higher than those in the normal group(P
