Gaucher disease: abdominal MR imaging findings in 46 patients.

Abdominal magnetic resonance imaging findings were reviewed in 46 patients with Gaucher disease. All patients had hepatosplenomegaly at the time of initial imaging. Splenic nodules were present in 14 patients (30%) and varied in signal intensity. These nodules were isointense on T1-weighted and hypointense on T2-weighted images. Splenic infarcts were seen in 15 patients (33%), and four of these patients (9%) also had subcapsular fluid collections. Both nodules and infarcts were present in the spleen in four patients (9%). Pathologic correlation was performed with specimens from two patients who underwent partial splenectomy. Focal areas of abnormal signal intensity were noted in the liver in nine patients (20%). They were either stellate or segmental, and may represent fibrotic septa with ischemic changes associated with aggregates of Gaucher cells. No changes were noted in the kidneys or abdominal lymph nodes.     

Outcome study: comparison of short-term vs long-term treatment in a residential community.

All patients admitted to a Residential Treatment Center (RTC), a drug-free hospital-based inpatient facility in February 1985 through July 1985, were followed-up 6 months after discharge. The results are contrasted with those obtained in 1973 in a similar follow-up study. Length of stay at RTC had been reduced from 1 year in 1973 to 3 months in 1985. Six months after discharge, the longer length of stay in 1973 appears to be almost twice as effective as the 3-month program in 1985.     

APPLICATION OF ACUPOINT-INJECTION THERAPY TO PAIN SYNDROME: CLINICAL ANALYSIS OF 250 CASES

In this paper,250 cases of headache,shoulder pain,lumbago and leg pain weretreated with 20％Angelicae Sinensis mixed with Vitamine B_(12) point-injection therapy.The total effective rate was 95.2％and in which the cure rate was 53.6％.Authors have found a close correlation between the effectiveness and the duration of disease.     

Effect of meal volume on gastric emptying

Abstract While the volume of a liquid meal has been identified as the principal accelerator of gastric emptying of liquids, the relationship between meal volume and gastric emptying of solids has been controversial. With solid foods, the need to reduce solid foods into small particles (trituration) before passage might obscure the effect of meal volume on solid propulsion. To distinguish trituration from driving force as the rate-limiting factor for emptying, 75 (1.6 mm) nylon spheres were fed along with different amounts of steak meals (150, 300 and 600 g), or alternatively, 50, 100 or 200 (1.6 mm) nylon spheres were fed to six dogs with 300 g steak meals. To examine the effect of meal volume on gastric emptying, we studied the effect of different meal volumes on the speed of gastric emptying of liquids (150, 300, 600 and 1200 ml of phosphate buffer) and solids (150, 300 and 600 g of cooked beef steak) in five dogs with duodenal fistulas. Intestinal inhibition was eliminated by diverting all chyme through the fistulas. In the absence of intestinal feedback, we found that gastric emptying of steak and spheres were different in that steak emptying was independent of meal volume (g min^-1 was constant across 150–600 g) while sphere emptying was affected by the number of spheres in the stomach and that liquid emptying was dependent on the meal volume (ml min^-1 increased across 150–1200 ml). Thus, meal volume accelerated gastric emptying provided the process is not rate-limited by trituration.     

米非司酮对人子宫内膜癌HHUA细胞ER、PR及亚型体外作用的研究

目的　探讨抗孕激素米非司酮体外对人子宫内膜癌HHU A细胞ER、PR及亚型的影响及其与抗肿瘤作用的相关性。方法　体外培养子宫内膜癌HHU A细胞,不同浓度米非司酮处理细胞4 8小时,采用逆转录-聚合酶链反应(RT- PCR)半定量法检测PR- A m RNA,PR- B m RNA的表达水平;应用免疫组化法检测HHU A细胞ER、PR受体蛋白的表达变化。结果　米非司酮(5 μmol/ L)显著地降低HHU A细胞PR- B m RNA和PR受体蛋白的表达水平(P<0 .0 5 ) ,但增加米非司酮剂量并不能增强其降调作用。抗孕激素米非司酮对HHU A细胞PR- Am RNA和ER受体蛋白表达无明显影响(P>0 .0 5 )。结论　抗孕激素米非司酮可明显降调子宫内膜癌HHU A细胞PR- B m RNA水平和PR蛋白的表达,并与抑制癌细胞增殖密切相关     

Survival following hydrofluoric acid ingestion.

Systemic toxicity after significant dermal exposure to hydrofluoric acid includes rapid development of hypocalcemia and hyperkalemia, leading to ventricular fibrillation. Similar dysrhythmias have occurred in patients after ingestion of sodium fluoride-containing compounds. Ingestion of hydrofluoric acid could induce similar cardiac toxicity; however, reported cases of hydrofluoric acid ingestion rarely have been described, and the rapid death of these patients has not allowed verification of this hypothesis. On two separate occasions, a 70-year-old woman ingested up to 2 oz of a 8% hydrofluoric acid-containing solution. Recurrent ventricular fibrillation with concurrent hypocalcemia and hypomagnesemia complicated her first episode, whereas a more aggressive administration of calcium and magnesium may have prevented dysrhythmias in the second episode. Survival from ventricular fibrillation after hydrofluoric acid ingestion has not been reported previously and suggests a role for aggressive empiric calcium and magnesium replacement.
