目的分析鼻内镜下射频及明胶海绵局部填塞治疗顽固性鼻出血的临床疗效。方法选取2021年6月至2023年6月抚州市第一人民医院收治的60例顽固性鼻出血患者作为研究对象,按照随机数字表法分为观察组与对照组,每组30例。观察组接受鼻内镜射频及明胶局部海绵填塞治疗,对照组接受单纯鼻内镜下射频治疗。比较两组临床疗效、治疗情况、生命质量、疼痛程度及并发症发生情况。结果观察组治疗总有效率为96.67%,高于对照组的73.33%,差异有统计学意义(P<0.05)。观察组出血量少于对照组,通气恢复时间、鼻黏膜恢复时间、住院时间均短于对照组,差异有统计学意义(P<0.05)。治疗后,两组躯体功能、心理功能、社会功能、物质生活评分及总分均高于治疗前,且观察组高于对照组,差异有统计学意义(P<0.05)。治疗后,两组视觉模拟评分法(VAS)均低于治疗前,且观察组低于对照组,差异有统计学意义(P<0.05)。观察组并发症发生率为3.33%,低于对照组的20.00%,但组间比较差异无统计学意义。结论鼻内镜下射频及明胶海绵局部填塞治疗顽固性鼻出血患者效果显著,可改善患者生命质量,缓解疼痛,且安全性较高,值得临床推广应用。

Multi-Protocol Label Switching is a technology that combines the simplicity of IP routing with the high-speed switching of ATM . In this paper,we focus on the analysis on the key technology of MPLS VPN, and points out the advantages of MPLS VPN network. We then propose the key points to implement MPLS/BGP VPN network. In the end we give an example to verify the feasibility of the scheme that applys general VPN technology to edge network.

Based on the CTD data obtained in the southern Taiwan Strait and its adjacent areas in August and September of 1994, the distributional features of the temperature and salinity in the studied area have been analyzed in detail. The results are as follows: (1) There are two low temperature and high salinity regions in the nearshore area between Dongshan and Shantou and in the southeastern Taiwan Shoal, respectively, which may be caused by upwellings. (2) There exists a cold eddy in the northwestern sea area and a warm eddy with two high temperature cores in the eastern sea area of the Dongsha Islands, which are related to the anti-cyclonic turning of the seawater near the Dongsha Islands. (3) A westward high temperature and high salinity water tongue extends through the northern Luzon Strait and reaches the sea areas near the Dengsha Islands and southern Taiwan Strait.

Using the CTD data investigated at about 330 stations in the southern Taiwan Strait, the northeastern South China Sea and their adjacent seas in August and September of 1994, this paper anayses the sectional distributions of salinity in 10 selected sections and discusses the possibility of the Kuroshio's intrusion into the northeastern South China Sea and the southern Taiwan Strait. The results show that: as the main stream of Kuroshio passes by the northern Luzon Strait during the survey period, the 'Kuroshio-influenced water' with some hydrological features of the Kuroshio may extend through the Luzon Strait to the sea areas near both the Dongsha Islands and the Taiwan Shoal of the southern Taiwan Strait.

相对不起诉制度是宽严相济刑事司法政策在刑事诉讼中的具体体现。但检察机关适用相对不起诉时程序繁琐,加上起诉工作考核机制以不起诉率作为公诉工作好坏的考核指标,导致相对不起诉在司法实践中适用率过低,背离司法规律和设立该制度的初衷。在提倡宽严相济刑事司法政策的今天,有必要使相对不起诉制度实现价值回归。

Bottom water coning is the main reason to reduce the recovery of horizontal bottom water reservoir. By water coning, we mean the oil-water interface changes from a horizontal state to a mound-shaped cone and breaks through to the wellbore. Autonomous inflow control device(AICD) is an important instrument maintain normal production after bottom water coning, however, the resistance increasing ability of the swirl type AICD is insufficient at present, which seriously affects the water control effect. Aiming this problem, this paper designs a multi-stage resistance-increasing and composite type AICD. The separation mechanism of oil-water two phases in this structure, the resistance form of oil-water single phase and the resistance-increasing principle of water phase are analyzed. Establishing the dual-phase multi-stage separation and resistance-increasing model, and verified by measuring the throttling pressure drop and oil-water volume fraction of the AICD, it is found that the composite type AICD has the effect of ICD and AICD at the same time, which can balance the production rate of each well section at the initial stage of production, delay the occurrence of bottom water coning. In the middle and later stages of production, water-blocking can be effectively increased to achieve water control and stable *** structural sensitivity analysis, the influence law of various structural parameters on the water control performance of composite AICD was obtained. The simulation calculation results show that,compared with the existing swirl type AICD, composite AICD has higher sensitivity to moisture content,the water phase throttling pressure drop is increased by 4.5 times on average. The composite AICD is suitable for the entire stage of horizontal well production.

In the present paper, the primitive equations, which can be used to simulate the large-scale motion of the ocean and atmosphere, are considered in the three-dimensional domain bounded below by a fixed solid boundary and above by a free-moving boundary. The global existence and uniqueness of strong solutions are established, and the long-time convergence to the equilibrium state is shown to be either at an exponential rate for the horizontal periodic domain or at an algebraic rate for the horizontal whole space.

The reliability of a network is an important indicator for maintaining communication and ensuring its stable operation. Therefore, the assessment of reliability in underlying interconnection networks has become an increasingly important research issue. However, at present, the reliability assessment of many interconnected networks is not yet accurate,which inevitably weakens their fault tolerance and diagnostic capabilities. To improve network reliability,researchers have proposed various methods and strategies for precise assessment. This paper introduces a novel family of interconnection networks called general matching composed networks(gMCNs), which is based on the common characteristics of network topology structure. After analyzing the topological properties of gMCNs, we establish a relationship between super connectivity and conditional diagnosability of gMCNs. Furthermore, we assess the reliability of g MCNs, and determine the conditional diagnosability of many interconnection networks.
