| 1 | Bacteriophage therapy against Enterobacteriaceae显示文摘The Enterobacteriaceae are a class of gram-negative facultative anaerobic rods, which can cause a variety of diseases, such as bacteremia, septic arthritis, endocarditis, osteomyelitis, lower respiratory tract infections, skin and soft-tissue infections, urinary tract infections, intra-abdominal infections and ophthalmic infections, in humans, poultry, animals and fish. Disease caused by Enterobacteriaceae cause the deaths of millions of people every year, resulting in enormous economic loss. Drug treatment is a useful and efficient way to control Enterobacteriaceae infections. However, with the abuse of antibiotics, drug resistance has been found in growing number of Enterobacteriaceae infections and, as such, there is an urgent need to find new methods of control. Bacteriophage therapy is an efficient alternative to antibiotics as it employs a different antibacterial mechanism. This paper summarizes the history of bacteriophage therapy, its bacteriallytic mechanisms, and the studies that have focused on Enterobacteriaceae and bacteriophage therapy. | Youqiang Xu Yong Liu Yang Liu Jiangsen Pei Su Yao Chi Cheng | 2015 | Virologica Sinica2015，30，1： | 10 |
| 2 | Design and Implementation of a Wideband HF Channel Simulator显示文摘The paper presents a wideband high frequency (HF) channel simulator. The simulation consists of a software simulation of a direct-sequence spread-spectrum (DSSS) HF system with RAKE receiver. The validity of the HF channel simulator is demonstrated by the analysis of the scattering function and example results of the simulator. The performance of DS system under HF channel and noise are also presented. The simulation results and theoretical analysis show that a straightforward DS system may properly mitigate the intersymbol interference (ISI) distortion of the HF channel while perform badly under the HF noise and interference. | XiangQien SunHong GanLiang-Cai JiangSen | 2004 | Wuhan University Journal of Natural Sciences2004，9，2： | 1 |
| 3 | TURBO EQUALIZATION WITH JOINTLY GAUSSIAN EQUALIZER显示文摘A Jointly Gaussian (JG) equalizer is derived for turbo equalization based on an augmented real matrix representation of channel model and a Gaussian approximation of the received symbol sequence. Using matrix inversion lemma and Cholesky decomposition, a lowcomplexity implementation of JG equalizer is also presented. The simulation results and complexity comparison confirm that turbo equalization with JG equalizer has a better performance and a lower complexity than the existing turbo equalization with linear minimum mean squared error equalizer. | JiangSen SunHong LiPing | 2005 | Journal of Electronics(China)2005，22，2： | 0 |

| 5 | Study on the activity and phenotype of decidual natural killer cells in patients with unexplained habitual abortions显示文摘Objective:To determine the activity and phenotype of decidual natural killer (NK) cells in patients with unexplained habitual abortions (UHA).Methods:A total of 32 patients with UHA were studied, and 20 cases of normal pregnant women were selected as control group. The levels of CD56 +CD3 - NK cells and their CD56 +CD16 -, CD56 +CD16 + subsets in decidua were detected using two color flow cytometric analysis.The NK cells activity was measured by a chromium 51( 51 Cr) release cytotoxicity assay,with K562 human myeloid leukaemia cells as targets.Results:Compared with control group, the proportion of CD56 +CD3 - NK cells in decidual mononuclear cells(DMC) of UHA patients had no difference, but the CD56 +CD16 - NK cell subset decreased and the CD56 +CD16 + subset increased significantly (P<0.05). The decidual NK cells activities of UHA patients were higher than those of normal controls (P<0.05).Conclusions:NK cell is predominant lymphocyte in normal decidua and plays an important role in maintaining successful pregnancy. Abnormally raised activity and disbalanced CD56 +CD16 +, CD56 +CD16 - subsets of decidual NK cell are associated with UHA and may play a role in reproductive failure. | DongRuiying LiHongrong LuJiming LiuHaiying LiXiaomei CuiBaoxia JiangSen | 2004 | 现代妇产科进展2004，13，5： | 0 |
