[Expression of KDR in medulloblastoma and its clinical implication].
To gain an insight into the possible relationship between the expression of kinase insert domain-containning receptor (KDR) and the prognosis of medulloblastoma. ⋯ KDR was expressed in most of the medulloblastomas, not only in the endothelial cells of tumor vasculature, but also in tumor cells. The expression level of KDR had a negative correlation with the survival time, thus it might be used as one of the prognosticators of medulloblastoma.

Randomized Controlled Trial Clinical Trial[Response to milrinone treatment in patients with chronic congestive heart failure].
The objective of this study was to examine the efficacy of milrinone in chronic congestive heart failure. In this randomized, double-blind, placebo-controlled trial, 30 patients with class III or IV chronic congestive heart failure were randomly assigned to receive milrinone (n = 15) or placebo (n = 15). The results showed that in the milrinone group, stroke volume increased from 38.50 +/- 5.34 to 64.93 +/- 6.46 ml (P < 0.001), cardiac output increased from 3.39 +/- 0.42 to 5.28 +/- 0.55 L/min (P < 0.001), cardiac index increased from 2.01 +/- 0.42 to 3.21 +/- 0.57/min/m2 (P < 0.001) and ejection fraction increased from 0.23 +/- 0.05 to 0.35 +/- 0.06(P < 0.001). ⋯ Milrinone favourably influenced the symptoms and heart function in 11/15(73.3%) patients. In the placebo group, only 4/15(26.7%) patients had such response (P < 0.05). These data indicate that milrinone is effective for improving the hemodynamics status and heart function in patients with chronic heart failure.

[The diagnostic value of hysteroscopy on postmenopausal bleeding].
The objectives of this study were to investigate the causes of postmenopausal bleeding and evaluate the diagnostic value of hysterscopy. Using the diagnostic technique of hysteroscopy and directed biopsies, the authors analysed the causes of postmenopausal bleeding of 234 patients undergoing hysteroscopy. The results showed that atrophic endometrium was the most common cause of postmenopausal bleeding and that endometrial hyperplasia, endometrial carcinoma/precancerous lesion, and submucous leiomyoma/endometrial polyp were also common in the patients with postmenopausal bleeding. ⋯ In terms of age and menopause time, there were significant differences (chi 2 = 3.36, P < 0.01; chi 2 = 3.92, P < 0.01 respectively)between the patients with postmenopausal bleeding in the benign changes group and those in the malignant changes group. So the combined use of hysteroscopical technique and directed biopsies is of great significance in finding out the causes of postmenopausal bleeding, making a definite diagnosis of endometrial carcinoma and precancerous lesion, and further preventing the occurrence of endometrial carcinoma. The examination of hysteroscopy is an effective and valuable method for diagnosing postmenopausal bleeding.

[The establishment of a modified lateral fluid percussion model of brain injury in rat and the pertinent pathologic changes].
For the purpose of studying the molecular mechanism of the traumatic brain injury, we have established a reproducible graded lateral fluid percussion model of experimental brain injury in the rat with a modified fluid percussion device. The device consists of a stainless steel cylindrical reservoir instead of the plexiglass reservoir, a steel reservoir filled with compressed gas instead of the pendulum for making more accurate percussion pressure, an apparatus for releasing the pressure immediately after the percussion, and a computer for recording and storing the percussion data. ⋯ The severity of pathologic changes increased with the magnitude of percussion. The results indicate that the new device could inflict reproducible graded lateral fluid percussion brain injury on rats and the model can be used for the studies of neuropathologic and molecular mechanism of brain injury.
