引言长链腈是天然物质,在许多柱上都能顺利地进行色谱分析。据报道,阿匹松、硅酮类和聚乙二醇(4000)单硬脂酸酯均可对其提供良好的分离。如果要求从不饱和的和多不饱和的长链睛中分离出饱和腈,可采用聚酯柱。腈基因是高度电负性的,大概是所有功能团中极性最大的,当在极性和非极性柱上进行分离时,这种极性即表现出来。在dEGS柱上,腈的保留时间至少是相等链长甲酯的两倍。据此,可以预言,含腈液相应是有效的、高极性物质。这一预言已被Tenny等证实。

Background:cutaneous T-cell lymphoma (cTcL) is a slowly progressive malignancy for which there is no cure. Therefore, accurate prediction of prognosis is important for the conduct of clinical trials and for counselling of individuals. Objectives:To improve prediction of survival in patients with cTcL. Methods:Prognostic factors including tumour-node-metastasis (TNM) criteria and the cTcL Severity Index (cTcL-SI) were analysed using a Weibull model for multivariate analysis in a sample of 62 patients with classical cTcL (mycosis fungoides and Sézary syndrome). The Brier score was used to quantify the quality of individual prediction. Results:Estimated 5-year survival rate (SR5) differed according to TNM stage:stage IA, 100%(95%confidence interval 70-100%); IB-III, 86%(73-100%); IVA, 54%(32-91%); IVB, 0%(0-52%). In a multivariate analysis, two independent prognostic factors were identified:lymph node (P=0.036) and blood involvement (P=0.015). A probability of survival model showed correlation of cTcL-SI with survival in patients with cTcL-SI > 20 according to the following formula:SR5 = 124-2×(cTcLSI)%. calibration of SR5 against cTcL-SI-independent cTcL subsets revealed underestimation of Sézary syndrome. When cTcL-SI parameters were adjusted accordingly, the probability of survival model d.d.not change significantly, while SR5 values became adequate. In addition, cTcL-SI was shown to be superior to TNM by 30%regarding individual predictive power. conclusions:Probability of survival in cTcL can be accurately predicted by a cTcL-SI-based survival rate formula. careful monitoring of lymph node and blood compartments and quantification by cTcL-SI are reliable tools for follow-up of patients with cTcL and allow progression-adjusted prediction of prognosis.

We sought to determine the outcomes of a screening program for hepatitis c virus(HcV) *** 536 veterans initially screened between July 2000 and June 2001 for risk factors and then tested positive for antibody for HcV,only 260(48.5%) kept their initial appointments for further evaluation;51 were not viremic and only 19(9.1%) were treatment *** the 276 who d.d.not keep their initial appointments,92 were subsequently evaluated over the next 2 years and 23(25%) were treatment eligible,along with another 15 from the first ***,with appropriate intervention and long-term follow-up,there were 57 treatment *** conclusion,most veterans who tested positive either failed to keep their appointment or were ineligible for treatment when first *** the following 2 years,some were lost to follow-up,many continued to have contraindication(s) to antiviral therapy,and relatively few were treatment cand.d.tes.

作者： Iaco P.d. ceccaroni M. Alboni c. 朱磊 department of Gynecology andObstetrics S. Orsola-Malpighi Hospital University of Bologna via Massarenti 13 40138 Bologna Italy

Objective: To evaluate the overall incidence of transvaginal evisceration following hysterectomy and to assess the risk associated with indication, route of surgery, age and vaginal cuff closure technique. Materials and methods: A database was used to identify all patients undergoing hysterectomy from 1995 to 2001 at our institution and all the patients admitted for vaginal evisceration during the same period. Each vaginal evisceration was analyzed for time of onset, trigger event, presenting symptoms, details of prolapsed organs and type of repair surgery. Results: Of the 3593 patients enrolled in the study, 63.5% underwent abdominal hysterectomy, 33.0% vaginal hysterectomy, and 3.5% laparoscopic hysterectomy. Ten patients (0.28% ) presented to the emergency room with vaginal evisceration. No statistical differences in evisceration rates were seen according to the route of surgery. No differences were found between the 1440 patients who had closure of the vaginal cuff and the 2153 who had an unclosed cuff closure technique. conclusions: Our data suggest that, in young patients, sexual intercourse is to be considered the main trigger event before the complete healing of the vaginal cuff while, in elderly patients, the evisceration is a spontaneous event. Uterine prolapse was not associated with a higher rate and the route of surgery or vaginal cuff closure technique d.d.not influence the dehiscence rate.

共采用76头母猪(1～4胎)进行试验,来确定颗粒日粮对母猪及其仔猪生产性能的影响。在21 d的哺乳试验中,母猪喂粉状(玉米磨碎至粒度500～600μm)或颗粒(直径0.48 cm)形式的玉米-豆粕基础日粮。结果,日粮形状不会影响酸性洗涤纤维摄取量(AdFI)或哺乳期失重(P≥0.15)。同时,每窝猪的断奶仔猪头数、仔猪存活率、每窝仔猪增重,断奶至发情的天数不受处理的影响(P≥0．15)。然而,喂颗粒饲料的母猪失去较少的背膘(0．13 cm,PdM)、氨(N)和总能(GE)消化率分别提高6％、9％和9％,而每天排出的dM和N分别减少90 g和2 g(P<0．001)。总之,在不分胎次母猪中,使用颗粒饲料不仅不会影响其仔猪的生产性能,而且可提高母猪的养分消化率、减少养分的排出。
