Wavelength and bandwidth allocation is important for multicast communication in optical networks. In this paper,a new method based on scheduling theory is proposed. The proposed method formulates wavelength bandwidth capacity as a large rectangle and these multicast stream bandwidth requirements as small rectangles. It treats the wavelength and bandwidth allocation question as a rectangle packing problem. The proposed algorithm solves the problem by taking quasi-human strategy with Euclidian distance. It is an effective heuristic algorithm to quickly solve multicast stream bandwidth allocation problem in optical networks by theoretic analysis. Further simulation experiments show the bandwidth allocation algorithm can increase network utilization and have a good fairness performance for unicast stream and multicast stream in optical networks. The results indicate the effectiveness of the algorithm.

Objective： To observe the clinical effect of point application using Chinese herbal medicine for chronic cough in children. Methods： A total of 200 children with chronic cough were randomly allocated into an observation group and a control group, 100 cases in each group. Conventional Western medication was used for cases in the control group, whereas conventional Western medication plus point application using Chinese herbal medicine were used for cases in the observation group. Changes of indexes including eosinophils （EOS）, peak expiratory flow （PEF） and forced expiratory volume in one second （FEV1） were observed before and after treatment. In addition, the clinical effects were compared between the two groups. Results： After treatment, coughs in children were alleviated in both groups; however, it took a shorter period of time for cough alleviation in the observation group than that in the control group （P^0.01）. On the 28th day of treatment, the EOS, PEF and FEVl were improved in both groups （P〈0.01）, and the improvements were more significant in the observation group （P〈0.05）. Additionally, the frequencies of cough variant asthma attacks were decreased in both groups, but a better effect in the observation group than the control group. Conclusion： Complementary point application using Chinese herbal medicine could substantially improve the clinical effect, alleviate coughs and benefit lung functions.

针对基于三态内容寻址存储器(TCAM,ternary content addressable memory)的深度报文检测(DPI,deep packet inspection)存在的高功耗问题,提出一种分级DPI方法BF-TCAM。第一级采用低功耗的并行布鲁姆过滤器(bloom fliter)排除无需检测的正常报文;第二级采用TCAM对真正需要检测的攻击报文和第一级的假阳性误判报文做进一步的检测。由于网络流量中大部分报文是正常报文,攻击报文在其中只占很少的部分,布鲁姆过滤器的假阴性(false negative)概率为0,可以保证不会产生漏检,假阳性概率很低,可以保证高速DPI检测的同时大大地降低功耗。

Sequence-activated chemiluminescence(CL) technique offers a unique approach to detecting specific biomolecules or cellular events with high sensitivity and spatial resolution. The fundamental principle behind sequence-activated CL probes involves tailoring highly-controllable CL signals in response to specific sequences or events of interest, thus enabling high-contrast signals under complex physiological conditions. This sequential activation could be triggered by enzymes, reactive oxygen species(ROS), biothiols or changes in the microenvironment. These unique sequence-activated CL probes bestow several advantages, including minimal background, deep-tissue penetration, and the ability of non-invasive or minimally invasive detection. The sequence-activated CL techniques represent a significant advancement in molecular imaging and diagnostics. In this mini-review, we focus on the latest developments in sequential CL probes, addressing the technical challenges and discussing the future trajectory by harnessing CL signaling and molecular recognition.

Pulmonary tumor embolisms due to renal cell carcinoma are common. In contrast, intra-operative puhnonary artery embolisms due to the release of large tumor fragments during surgery for retroperitoneal leiomyosarcoma have not been reported. When a massive tumor embolus does occur, a patient＇s survival depends on prompt surgical intervention.2 In this report, a patient experienced a pulmonary tumor embolism during resection of a retroperitoneal leiomyosarcoma, and the condition was successfully treated. However, for the hemodynamic collapse that occurred, a puhnonary arteriography was followed by an emergency puhnonary embolectomy with cardiopulmonary bypass.
