BACKGROUND Multiple myeloma(MM)complicated with extramedullary disease(EMD)has a poor prognosis and is a limiting factor in the treatment of MM,and no standard treatment is recommended in international *** studies have reported MM with periorbital *** SUMMARY In this paper,the clinical characteristics and survival of seven patients with multiple myeloma and orbital are described and *** common ocular symptoms were blurred vision,proptosis and/or eye movement disorders,IgG type MM may be a risk factor for orbital *** them,six patients were treated with bortezomib-based *** median overall survival(OS)and progression free survival for the entire cohort were 48 and 33 mo,respectively,which was much worse than the OS reported for MM patients without orbital *** Orbital MM may have significantly shortened survival for the entire cohort,so multidisciplinary collaboration is emphasized and recommended in the diagnosis and treatment of these difficult cases.

为了提高扩展二元相移键控(Extended Binary Phase Shift Keying,EBPSK)系统的抗衰落性能,并简化解调器结构,提出了一种对称的扩展二元相移键控(Symmetric-EBPSK,S-EBPSK)调制方式,以"0"、"1"码元对称的调制波形为主要特征,采用简单有效的冲击滤波加比较判决的方法来完成解调,并从理论上推导了S-EBPSK系统的功率谱,及加性高斯白噪声(Additional White Gaussian Noise,AWGN)信道下系统的理论误码率公式.仿真结果表明了所提方案实现简单有效,且无论在AWGN信道还是衰落信道下,均表现出了明显的性能优势.

为了克服单一使用中值滤波方法去除脉冲噪声会造成图像细节信息丢失的缺陷,提出一种基于弹簧质点模型检测的迭代中值滤波算法.首先将被检测点作为中心点,其周围8个方向的像素点对该中心点的拉力组成一个平面内的弹簧质点模型,根据弹簧... 详细信息

为了克服单一使用中值滤波方法去除脉冲噪声会造成图像细节信息丢失的缺陷,提出一种基于弹簧质点模型检测的迭代中值滤波算法.首先将被检测点作为中心点,其周围8个方向的像素点对该中心点的拉力组成一个平面内的弹簧质点模型,根据弹簧质点模型的稳定条件,即平面汇交力系的平衡原理来检测像素点是否为噪声点;然后通过迭代方法,只用信号点来修改噪声点的像素值.实验结果表明,与传统的滤波算法相比,文中算法可以更有效地去除图像中的脉冲噪声并且保留原图像的细节.

Internal migration in China has introduced critical challenges to the education and health of migrant adolescents. The aim of this study was to explore the differences in sexual knowledge and attitudes among migrate and local adolescents. Survey research with a total of 616 adolescents in grades equivalent to US 10th and 11th grades including 113 migrants completed a selfadministered questionnaire. Misconceptions of adolescent physical development, sexual activity, marriage, birth control, sexually transmitted diseases and the probability of pregnancy were found in most of the migrant adolescents. Significantly lower attitudinal scores were found for the sub-scales of clarity of personal sexual values, understanding of emotional needs, social behavior, sexual responses;attitudes towards gender role, birth control, premarital intercourse, use of force in sexual activity, the importance of family and satisfaction with social relationship in migrant adolescents. Migrant adolescents have a low level of knowledge of sexual activities. The content of education programs should include engagement in sexual behavior to equip adolescents with unbiased and factual knowledge. The adolescents have a high demand for family support. School based sex education programs should involve the participation of parents to address these issues.
