Objective: The recto-vaginal fistula is an abnormal communication between the previous wall of the rectum and the posterior face of the vagina through the recto-vaginal septum. They are often due to the obstetric traumas and they can be of post-surgical origin. Methods: We report five cases of patients with obstetric recto-vaginal fistula and all of the patients have surgical intervention with a resection of the fistulous route and rectal wall. Results: The patient did not present any recidivating and the evolution is satisfactory without complications or recidivating. Conclusion: The treatment of recto-vaginal fistula is often difficult exposed to recurrence;and the therapeutic indications must be adapted to every type of fistula by taking into account its size, its location and its etiology.

Introduction: Corticosteroid-induced lipomatosis are uncommon situation. We report a case of an extensive lipomatosis in a rheumatoid arthritis patient, who received a long term steroid therapy. Case report: A 49-year-old rheumatoid arthritis woman, who received for two years a mean dose of 15 mg/ day of prednisone equivalent, was admitted to the hospital for a six months history of progressive abdominal distension and dyspnea. Physical exam revealed typical symptoms of Cushing’s syndrome and an important increase of abdominal volume. Lipomatosis diagnosis with mesenteric, mediastinal, retroperitoneal and epidural localizations, was rapidly confirmed by sonography and computed tomography (CT) exams. Management was based on corticosteroid reduction as well as use of hygiene and dietary measures. Therapeutic efficacy was noted on a clinical basis within one year. Discussion: lipomatosis occurs as a less known complication of long-term steroid therapy. Its localizations are numerous. Epidural and mediastinal lipomatosis are more frequent than mesenteric or retroperitoneal ones. Most frequently asymptomatic, lipomatosis could sometimes be revealed by false symptoms. Medical treatment including corticosteroid with drawal or reduction and calorie restriction, can lead to clinical improvement. Surgery is reseved in advanced forms with serious complications.

In this paper, we have used the distributed mean value analysis (DMVA) technique with the help of random observe property (ROP) and palm probabilities to improve the network queuing system throughput. In such networks, where finding the complete communication path from source to destination, especially when these nodes are not in the same region while sending data between two nodes. So, an algorithm is developed for single and multi-server centers which give more interesting and successful results. The network is designed by a closed queuing network model and we will use mean value analysis to determine the network throughput (b) for its different values. For certain chosen values of parameters involved in this model, we found that the maximum network throughput for β≥0.7?remains consistent in a single server case, while in multi-server case for β≥ 0.5?throughput surpass the Marko chain queuing system.

小型温室棚作为农业生产的重要设施,可为农作物创造一个温度适宜的、受保护的生长空间,保证作物正常生长、促进作物早熟。以确保重庆地区春冬季烟苗正常发育、维持温室内适宜的土壤温度为导向,对温室棚内温度进行了试验和数值模拟,探究了温室棚内温度分布规律,并在此基础上分析生物质发酵产热对温室棚内土壤温度场的影响。结果表明:试验中埋设稻壳的温室棚内土壤温度平均提高3.5℃且温室棚中平均温度低于10℃的天数明显减少。埋设稻壳的温室棚中烟苗茎高和叶片数增长值最大,平均茎高从移栽时的7.8 cm增长到了12 cm,叶片数从平均5片增长到了11片,均大于未埋设稻壳试验组,这表明土壤中埋设稻壳有助于烟草的生长发育。数值研究表明温室棚内不同深度的土壤层温度变化状况一致,均呈现先降低后升高再降低的趋势。地温随土壤深度的增加而降低,地表下10 cm、20 cm的土壤层区域温度高于10.6℃、8℃,有利于烟苗在低温环境下正常生长。且土壤温度存在一定的昼夜温差,更利于烟苗发育。埋设稻壳的温室土壤层温度变化趋势与未埋设稻壳的温室一致,但其土壤层平均温度、最低温度至最高温度以及昼夜温差分别升高了2.3℃、1.1—5.5℃、4.8℃。试验和数值研究结果表明稻壳发酵产生的热量可以提高和维持温室内土壤温度,对土壤具有保温和热量补给的作用。

【目的】研究酸胁迫对不同烤烟品种幼苗生长的影响。【方法】以云烟116和云烟87为试验材料,采用水培研究不同酸度(pH 4.0、pH 5.0和pH 6.0)对烤烟幼苗根系、叶片亚细胞结构及生理生化指标的影响。【结果】相较于对照(pH 6.0),酸胁迫条件下,烤烟幼苗根系活力降低,根系发育缓慢甚至受到抑制;叶绿体和线粒体受到不同程度的损伤;丙二醛(MDA)含量以及超氧化物歧化酶(SOD)、过氧化物酶(POD)和过氧化氢酶(CAT)的活性均增加。相较于pH 5.0,处理6 d后,pH 4.0处理烤烟幼苗根系长度、根系表面积、根系体积和根尖数均下降;叶绿体膨胀变形,基粒片层扭曲,线粒体空洞化,无结构清晰的嵴,MDA含量增加,SOD、POD和CAT的活性均降低。【结论】酸胁迫抑制烤烟幼苗根系发育,损伤叶片亚细胞结构及抗氧化酶系统,且随着pH下降,烤烟幼苗受损程度更高。云烟116受到酸胁迫影响较大,云烟87表现出较强的耐酸性。

Matrix-assisted laser desorption/ionization (MALDI) is a preferred and widely used mass spectrometric technique for the analysis of macromolecules. Limited UV-LDI matrices are available for the analysis of biomolecules due to the restricted structural features to serve in the laser desorption/ionization mechanism with a problem of background signals appearing in the low mass region. This paper describes the application of Schiff base derivatives of acylhydrazide and isatin as alternate UV-LDI matrices for the analysis of peptides with significantly low background signals. Thirty one compounds have been successfully employed as matrices for the analysis of low molecular weight (LMW) peptides (α-Cyano-4-hydroxycinnamic acid (HCCA), a preferred choice for peptide analysis.

语篇回指是英汉语言共有的语言现象,虽然在表现形式上有着明显的差异,但是从认知角度看,这两者必定存在着一定的相似之处。认知语言学家van Hoek基于Langacker的概念参照点理论与Ariel的可及性指称理论,从认知角度进行指称研究,提出了回指规约机制,对句内回指研究提出了有效的指导。本文旨在通过van Hoek的回指规约机制,说明英汉语篇回指认知角度的异同,并提出相应英汉翻译方法。
