实践教学作为培养学生创新精神和实践能力的途径,在整个教育体系中占有重要地位.在实践发展历程中,单一主导实践观的影响下,实践教学存在各种问题,严重影响应用型人才培养的质量,因此应该将单一实践观加以整合,重构实践教学体系.在多重实践观关照下,整个教学体系应该以实践教学为核心,加强规范学习和身份认同,丰富职业经验,提高反思能力,关照实践能力的规范性、技术性和意义性.实践教学的途径应该是全方位、多层次的,不局限于道德规范培养和技术的应用,还要营造实践环境,形成实践共同体,并使学生由共同体的边缘走向中心的合法参与.

在属性基加密中,多个用户会共享公共属性,其中的一些用户可能会恶意地泄漏解密密钥,被追踪到的用户可能认为是管理机构泄漏密钥。为此,给出一个新的可追踪属性基加密方案,当被追踪到的用户质疑结构的可信性时,可运行问责算法确认是机构或用户的恶意行为。方案中的属性管理机构和身份管理机构均不能独立地解开系统中的密文。分析结果表明,该方案不仅实现用户的可追踪性,而且解决了可追踪密文策略属性基加密的机构可信依赖问题,实现了对管理机构的可问责性。

Background noise in the mechanical vibration signals has a great influence on signal processing and structural modeling. In this paper, a FastICA conjugate gradient algorithm based on negative entropy and independent component analysis (ICA) is presented. This algorithm has advantages of high computation effect, good convergence performance and robust. The experimental analysis results demonstrate the effectiveness of the proposed method in vibration signal separation from the background noise.

Objective: To observe the efficacy and safety of the TCM differentiation treatment combined with IFN-for chronic hepatitis B with HBeAg-positive.Methods: According to the method of the prospective cohort study,137 patients with the disease were divided into TCM combined with IFN-treatment group and IFN-control group.Results: After 48 weeks of treatment in both treatment and control group,the normalization rates of ALT were 54.8% and 42.7%respectively(P0.05);the patients proportion of HBV-DNA below the detection value were 47.06% and 34.78% respectively(P0.05);the HBeAg negative conversion rates were 50.0% and 34.8% respectively(P0.05);and the HBeAg seroconversion rates were 50.0% and 30.4% respectively(P0.05).The incidence of adverse events in both groups were similar,but the incidence of fatigue and decreased appetite were 15.5% and 28.9% respectively(P0.05).Conclusion: The therapy of differentiation in TCM combined with IFN-can increase HBeAg seroconversion rate of the chronic hepatitis B patients with HBeAg-positive and improve IFN-induced fatigue,decreased appetite and other adverse reactions.

目的:评价基于“阳黄-阴阳黄-阴黄”辨证论治模式治疗慢性重型肝炎的临床疗效和安全性.方法:采用多中心、随机、平行对照临床研究方法,将165例慢性乙型重型肝炎患者分为对照组和中医辨证治疗组,对照组采用基础治疗方案,治疗组在对照组基础上加用中医辨证治疗,疗程8周,随访24周,观察治疗前后各组患者的症状积分、肝功能指标,并发症发生率、不良反应及12、24周病死率.结果:中医辨证治疗组能显著改善患者症状,促进肝功能恢复,减少并发症的发生率,将慢性重型肝炎的整体临床有效率提高至76.2％,优于对照组(P＜0.05)；治疗组24周病死率36.9％,对照组为45.7％,降低近10％；两组均未见有明显不良反应.结论:在西医综合治疗基础上,结合中医基于阳黄-阴阳黄-阴黄辨证论治模式治疗慢性重型肝炎,具有减少并发症,提高临床疗效,降低病死率,安全性高等优势.

Objective:To discuss the distribution and evolution characteristics of syndrome dampness heat-blood stasis-spleen deficiency of chronic severe hepatitis B(CSHB).Methods:Aaccording to the inclusive criteria and exclusive criteria of the study,438 patients with CSHB were retrospectively investigated on four diagnostic information of traditional Chinese medicine.Frequency analysis and variable cluster analysis were used on the common symptoms and signs of traditional Chinese medicine with different phases and different clinical stages.Results:The main symptoms and signs in early stage were red tongue,greasy yellow tongue coating,taut rapid pulse or taut slippery pulse,dry mouth and bitter taste.The main symptoms and signs in middle stage were dull complexion,sublingual varices,dark and purple in tongue texture.The main symptoms and signs in advanced stage were sublingual varices,subcutaneous petechia and ecchymosis,loose stools,abdominal distension,dark and purple tongue,dull complexion.The symptoms of spleen deficiency and blood stasis became more obvious as the course of the disease prolonged in early stage patients.Conclusion:The early stage of CSHB patients is mainly dampness-heat syndrome accompanied by spleen deficiency and blood stasis syndrome while mainly spleen deficiency and blood stasis syndrome accompanied by dampness-heat syndrome in middle and advanced stage.There is already spleen deficiency and blood stasis syndrome in the early stage of CSHB patients,which gradually progressed as the extension of the course.Therefore,the treatment of CSHB patients should be strengthened by warming Yang and invigorating the spleen based on clearing heat and detoxifying,cooling blood and promoting blood circulation.
