子宫肌瘤患者外周静脉与子宫静脉血管内皮细胞生长因子水平测定及临床意义

目的:探讨血管内皮细胞生长因子(VEGF)在子宫肌瘤发生和肌瘤生长中的作用。方法:手术中暴露子宫静脉后,抽取子宫静脉血3ml,同时抽取非输液肢体外周静脉血3ml。抽取配对正常妇女外周静脉血3ml。ELISA法测定VEGF水平。测量子宫重量、肌瘤总重量、肌瘤数目和最大肌瘤最大径线值。结果:子宫肌瘤患者子宫静脉血和外周静脉血VEGF水平分别为159.38±25.63pg/ml和76.35±26.61pg/ml,对照人群外周静脉血VEGF水平为42.53±29.47pg/ml。子宫静脉血中的VEGF水平明显高于外周静脉血(P=0.019),子宫肌瘤患者外周静脉血中的VEGF水平明显高于对照人群外周静脉血的VEGF水平(P=0.013)。子宫重量、肌瘤总重量、肌瘤数目、最大肌瘤最大径线都与子宫肌瘤患者子宫静脉和外周静脉VEGF呈显著正相关。结论:VEGF可能参与了子宫肌瘤的生长和病情发展。     

Assessment of long-term quality of life after laparoscopic and open surgery for Crohn''s disease

OBJECTIVE: Surgery for Crohn's disease (CD) is associated with a high recurrence rate and quality of life (QOL) in these patients is controversial. The aim of this study was to assess QOL in patients after laparoscopic and open surgery for CD by two different validated instruments, a generic nonspecific score and a specific gastrointestinal QOL index. PATIENTS AND METHODS: Patients with CD who underwent elective laparoscopic or open ileocaecal resection with primary anastomosis between 1992 and 2000 were followed for recurrence and surgery-related complications. QOL was assessed by the SF-36 Health Survey containing a mental (MCS) and a physical (PCS) component summary score and by the Gastrointestinal Quality of Life Index (GIQLI) developed by Eypasch. RESULTS: Thirty-seven patients with a mean age of 48.8 +/- 18.4 years including 23 females and 14 males were evaluated at a mean follow-up of 42.6 +/-25.8 months (minimum of 8 months). Twenty-one (57%) patients underwent laparoscopic resection and 16 (43%) open surgery. Both groups were well matched for age, gender, ASA class and body mass index. Fourteen (38%) patients developed recurrent disease and 3 (8%) had postoperative incisional hernias. Overall, QOL scores were 103 +/- 26.8 for the GIQLI, 47.2 +/- 11.8 for the PCS, and 49.2 +/- 11.5 for the MCS. The GIQLI correlated well with the SF36, correlation coefficient = 0.68 for GIQLI vs PCS (95% CI, 0.41,0.95) and 0.67 for GIQLI vs MCS (95%CI, 0.39, 0.95), respectively. When compared to the general US population, mean GIQLI scores (-13.8, P = 0.002) and mean PCS scores (-4.7, P = 0.001) were significantly lower in these patients than in healthy individuals. In a multivariate analysis of impact factors on QOL, recurrence within the follow-up period was the single significant determinant reducing the PCS (-35.1, P = 0.026) and the GIQLI (-36.1, P = 0.018). CONCLUSION: QOL is significantly reduced in patients with CD at long-term follow-up after both laparoscopic and open surgery. Recurrence is the only factor adversely affecting QOL of CD patients in remission irrespective of the operative technique applied.

Changing prevalence and knowledge of urinary incontinence among Hong Kong Chinese women

A territory-wide telephone survey was conducted in Hong Kong to assess the prevalence, knowledge, and treatment-seeking behaviour of Chinese women with urinary incontinence, using validated Chinese version of Urogenital Distress Inventory (UDI-6) and Incontinence Impact Questionnaire (IIQ-7). Women, 540, aged between 17 to 77 years were interviewed. Of the respondents, 40.8% reported stress urinary incontinence, 20.4% had urge incontinence and 15.9% had mixed incontinence. Among these, 16.0% reported quality of life impairment; 9.3% felt frustrated with low morale, and 15.2% had nervous and anxiety problems. However, as many as 78.3% of the respondents did not know that stress urinary incontinence is a disease entity, and 60.6% thought that leakage of urine was a normal aging process. For those respondents having stress urinary incontinence, the first treatment of choice was physiotherapy. The second choice was medication, and surgical treatment was the last option. Respondents with stress urinary incontinence showed higher education level.

非糖皮质激素的免疫抑制方案对同种异体移植胰岛的保护作用

目的　评价非糖皮质激素的免疫抑制方案对防止大鼠同种异体胰岛移植排斥反应的效果。方法　大鼠同种异体胰岛移植后 ,分别应用他克莫司 (FK5 0 6 ) 霉酚酸酯 (MMF)和FK5 0 6 MMF 泼尼松 (Pred)行免疫抑制治疗两周 ,并设对照组 ,动态观察受者血糖、胰岛素及C肽变化 ,并作移植部位的形态学检测。结果　FK5 0 6 MMF组和FK5 0 6 MMF Pred组与对照组相比 ,移植胰岛存活时间明显延长 ,移植后 2个月在受者肝汇管区可见较多形态完整的胰岛细胞。FK5 0 6 MMF组维持术后正常血糖、胰岛素及C肽的时间超过 6 0d ,而FK5 0 6 MMF Pred组与前者比较 ,分泌C肽较少 (P <0 .0 5 ) ,血糖维持在较高水平 (P <0 .0 1) ,胰岛素水平两组差异无显著性。FK5 0 6 MMF Pred组停药两周以后的血糖水平较用药期间、停药两周内有明显降低 (P <0 .0 5 ) ,胰岛素和C肽分泌有所增多 ,但差异无显著性。结论　应用FK5 0 6 MMF和FK5 0 6 MMF Pred均有很强的免疫抑制效应 ,但糖皮质激素对胰岛细胞有毒性作用。小剂量FK5 0 6与MMF联用对移植胰岛细胞有较强的保护作用。     

Effects of mycophenolic acid on IL-6 expression of human renal proximal and distal tubular cells in vitro.

BACKGROUND: Interleukin-6 (IL-6) is a multifunctional cytokine which regulates immune responses and host defence mechanisms. IL-6 has been found to be increased in certain inflammatory conditions of the kidney, in which tubular epithelial cells play a pivotal role. Human renal tubular cells express IL-6. Until now no data about the effect of the immunosuppressant drug mycophenolic acid (MPA) on IL-6 expression were available. METHODS: Proximal and distal tubular epithelial cells (PTC/DTC) have been isolated immunomagnetically. Confluent monolayers were stimulated with interleukin-1beta (IL-1beta; 25 U/ml), IL-1beta+ MPA (0.25-50 micro M) or MPA alone for 48 h. Release of IL-6 protein into the supernatant was evaluated with an enzyme immunoassay, IL-6 mRNA expression was evaluated using the Quantikine mRNA kit. RESULTS: After IL-1beta stimulation, a highly significant 2.6- (PTC) and 3.8-fold (DTC) upregulation of IL-6 expression was detectable. IL-6 mRNA was upregulated by IL-1beta [1.57- (PTC) and 2.03-fold (DTC)]. MPA inhibited this cytokine-induced IL-6 expression in a dose-dependent manner. Incubation with the lowest MPA concentration had no effect on the stimulated upregulation, whereas all higher doses significantly decreased IL-6 expression. Dexamethasone significantly inhibited the cytokine-induced IL-6 protein release in PTC, but not in DTC. CONCLUSIONS: In this study we demonstrated for the first time an inhibitory effect of MPA on the stimulated IL-6 expression of renal tubular epithelial cells. In contrast to older data, which showed a synergistic upregulation of the expression of a CC-chemokine by a combination of cytokines and MPA, in the present study we could demonstrate an immunosuppressive effect of MPA on the expression of an important cytokine.     

Evaluating the responsiveness of the endometriosis health profile questionnaire: The EHP-30

OBJECTIVES: To evaluate the sensitivity to change of the Endometriosis Health Profile-30 (EHP-30) questionnaire. SETTING: The Women's Center, John Radcliffe Hospital, Oxford. DESIGN: Postal survey to 66 women undergoing conservative surgery for the treatment of endometriosis-associated pain. The EHP-30 and the Short Form-36 (SF-36) were administered 2 weeks before the operation, and 4 months post-operatively. At T2 a transition question was included to evaluate changes in patients health status. To evaluate responsiveness effect sizes, standardised response means, the index of responsiveness and the minimally and clinically important differences were calculated. RESULTS: Forty (66.6%) patients returned the questionnaires at time 1 and 2. Overall less responsive effect size scores were found for the SF-36 (0.1-0.5) compared to the EHP-30 (-0.1-1.1) for all patients who had undergone treatment. Minimally important differences and the index of responsiveness were overall higher for the EHP-30 (0.4-2.0) compared to the SF-36 (0.1-1.0). Change scores for four of the five scales were significantly correlated with women's responses to the transition question. CONCLUSIONS: Results suggest that the EHP-30 is sensitive to change. Its application in clinical trials should prove beneficial in assessing the impact of medical and surgical interventions upon quality of life for women with endometriosis.
