恶性冬眠瘤的临床病理和免疫组化及超微结构观察

目的：了解恶性冬眠瘤独特的临床病理和免疫组化及超微结构变化。方法：收集2例恶性冬眠瘤和4例粘液性脂肪肉瘤的临床资料,所有标本光镜常规切片观察,免疫组化染色检测CKp,SMA,RMA,MyOD1,S100,PCNA,p53。冬眠瘤和粘液性脂肪肉瘤各1例取新鲜组织做透射电镜观察。结果：恶性冬眠瘤与粘液性脂肪肉瘤有显著的组织学、免疫组化和超微结构的不同;例1与腺泡状软组织肉瘤的组织学和免疫组化改变相似,唯有超微结构不同。例2免疫组化与有腺泡样结构的肉瘤不同。结论：恶性冬眠瘤的诊断主要靠超微结构的观察和免疫组化染色。     

Growth, puberty and obesity after treatment for leukaemia

Final height, body proportions, pubertal growth and body mass index were studied retrospectively in 142 survivors of acute lymphoblastic leukaemia (ALL). Treatment consisted of combination chemotherapy and cranial irradiation (18 or 24 Gy). Significant standing height loss and disproportion, with a relatively short back, was seen in both radiation dose groups. Girls were more severely affected than boys. Pubertal growth was adversely affected, with a reduction in peak height velocity in both sexes. Puberty occurred early in girls but at the normal time in boys. Nearly half the group were obese at final height, with no significant difference in incidence between the sexes. The relative roles of cranial irradiation and chemotherapy in the disturbance of growth, puberty and body composition observed in survivors of childhood ALL remain unclear. The aetiology is almost certainly multifactorial, with radiation-induced growth hormone insufficiency, early puberty, steroids and chemotherapy all having a role.     

Renal transplantation and osteoporosis

A cross sectional study assessed the bone mineral density (BMD) of 20 young adult patients who received a renal transplantation in childhood. The BMD of the lumbar spine, mainly trabecular bone, and of the total body, mainly cortical bone, were measured and expressed as an SD score. Fourteen patients (70%) had a BMD SD score of the lumbar spine below -1, of whom six patients were below -2. Fifteen patients (75%) had a BMD SD score of the total body below -1, of whom seven patients were below -2, Both trabecular and cortical bone appeared to be involved in the osteopenic process. The cumulative dose of prednisone was inversely correlated to both lumbar spine and total body BMD SD score. In a multiple regression analysis the cumulative dose of prednisone appeared to be the only factor with a significant effect on BMD SD score. Most young adult patients who had received a renal transplantation in childhood had moderate to severe osteopenia. Corticosteroid treatment played a major part in the development of osteopenia in these patients.     

Cytokine-driven inflammatory response is associated with the hypermetabolism of AIDS patients with opportunistic infections

BACKGROUND: To assess a possible role of systemic inflammation in the resting metabolic response in AIDS patients with active secondary infections. METHODS: Fifty-two patients with AIDS-defined criteria and concomitant active infections and 19 healthy subjects were studied. Measurements were as follows: body composition assessed by bioelectrical impedance; resting energy expenditure (REE) by 30-minute indirect calorimetry; cytokine concentrations (IL-6, IFNalpha, TNFalpha, sTNF-R1) by ELISA; C-reactive protein (CRP), erythrocyte sedimentation rate, fibrinogen, and nutritional parameters by standard techniques. RESULTS: REE adjusted for fat-free mass (REEFFM) was significantly increased in AIDS patients despite 39% of them not being hypermetabolic. The patients were undernourished and were found to have increased levels of acute-phase proteins and increased concentrations of IL-6 and sTNF-R1 relative to controls. REE parameters were positively related to CRP, ESR, ferritin, IL-6, and sTNF-R1 and negatively related to albumin, prealbumin, and transferrin. CRP was an independent predictor of REEFFM in AIDS patients and explained 25% of its variability. Patients with severe inflammation (CRP > or = 37 mg/dL) were significantly hypermetabolic with respect to patients without inflammation (CRP < 6 mg/dL) and had higher levels of IL-6 and sTNF-R1 and lower levels of albumin and prealbumin. Although no significant differences were observed with respect to the infection type, patients with tuberculosis and Pneumocystis carinii infections had higher resting metabolic and inflammatory responses, whereas patients with recurrent bacterial pneumonia were normometabolic and had lower levels of inflammatory markers. CONCLUSIONS: Resting hypermetabolism observed in AIDS patients with concurrent active infections is related to the presence and severity of systemic cytokine-driven inflammatory response, which could reflect the type of secondary infection.     

Penetration of diltiazem into breast milk and its pharmacokinetics in the lactating rabbit

1. The aim was to investigate the milk transfer and pharmacokinetics of diltiazem (DTZ) in the lactating rabbit following DTZ intravenous (i.v.) administration. In addition, DTZ metabolism in mammary tissue and milk was also studied. 2. The pharmacokinetic parameters that largely determine drug disposition (AUC, VD, CL) showed no significant differences between the non-lactating and lactating rabbit. 3. When DTZ was administered to the lactating rabbit, the observed DTZ milk-to-blood AUC ratio (M/B) closely correlated with the calculated ratio, as predicted by a diffusional model, suggesting that DTZ passes into milk via non-ionic diffusion and that other factors which may affect the milk transfer seem to have limited relevance. 4. After a single intravenous dose of DTZ to the lactating rabbit, deacetyldiltiazem (M1) and demethyldiltiazem (MA) were observed in blood, but only M1 could be detected in milk. 5. In conclusion, DTZ seems to diffuse freely into milk after its i.v. administration to the lactating rabbit and should not be given to nursing mammals because of the potential risk for their young. This risk may be even higher because of the presence of M1 (a pharmacologically active metabolite) in milk after administration of the parent drug.
