Clinical manifestations of low bone mass in amenorrhea patients with elevated follicular stimulating hormone / 中华医学杂志(英文版)

<p><b>OBJECTIVE</b>To study the characteristics of low bone mass in amenorrhea patients with elevated follicular stimulating hormone (FSH).</p><p><b>METHODS</b>Amenorrhea patients with elevated FSH: Primary amenorrhea 18 cases, secondary amenorrhea 171 cases and age matched controls with normal menstruation, 180 cases. The descriptive parameters were: estrogen, alkaline phosphatase, urinary excretion of calcium to creatine ratio, cortical bone mineral density at the right radius measured by single photon absorptiometry and trabecular bone mineral density at the lumbar vertebra body measured by quantitative computerized tomography.</p><p><b>RESULTS</b>Average E(2) levels in amenorrhea patients is under 150 pmol/L with significantly higher alkaline phosphatase and urine calcium to creatine ratio values than the normal menstruation group. Cortical bone mineral density in the secondary amenorrhea group (655 +/- 69 mg/cm(2)) was significantly lower than that of the normal menstruation group (677 +/- 56 mg/cm(2), P < 0.01). Trabecular bone mineral density in the secondary amenorrhea group (145 +/- 26 mg/cm(3)) was significantly lower than that of the NOR group (192 +/- 28 mg/cm(3), P < 0.001). The disparity with the normal menstruation group is even greater in the primary amenorrhea group. Bone mineral density of the amenorrhea patients was negatively correlated with duration of the menopause.</p><p><b>CONCLUSIONS</b>Serum estrodiol levels in amenorrhea patients was so low that bone turnover was accelerated. This led to insufficient bone accumulation and a dramatically drop in trabecular bone mineral density. The extent was closely related to age of onset of amenorrhea and the duration of ovarian failure.</p>

Long-distance consultation system based on the technique of superhigh-definition display / 中华医院管理杂志

The paper gives an account of the building of the long-distance medical system, a project of Sino Japanese informationalized cooperation. It describes the configuration and structure of the long-range support system of clinical image diagnosis based on the Japanese technique of superhigh-defintion display, discusses the functions and characteristics of the long-distance medical system featured by superhigh-definition display and forecasts the prospects of the application of the system in China and the research and development of relevant projects.

The effect of progesterone on the intraluminal pressure and peristalsis of the ureter in dogs / 中国病理生理杂志

A The effect of progesterone on the intraluminal pressure and peristalsis of the ureter was studied in seven dogs (male 2, female 5). The results showed that the range of variations of the intraluminal pressure was obviously magnified and the peristalsis of ureter smooth muscles was exaggerated after intramuscular injection of progesterone, and the urine volume was about 1.5 times the volume before injection. This might account for the therapeutic effect of progesterone to expel the ureteral stone in the treatment of ureterolithiasis.
