Small intestinal biopsies showed subepithelial collagen deposition with varying degrees of villous atrophy and varying numbers of intraepithelial lymphocytes. Four patients had previous biopsies showing enteropathic changes without collagen deposition. Seven cases were associated with collagenous colitis and 1 also had features of lymphocytic colitis. Three patients also had collagen deposition in gastric biopsies. One case was associated with lymphocytic gastritis. Celiac disease (CD, gluten-sensitive enteropathy) was documented in 4 patients. Five patients made a clinical improvement with combinations of a gluten-free diet and immunosuppressive therapy. Two patients died of complications of malnutrition and 1 of another illness. Clonal T-cell populations were identified in 5 of 6 cases tested. Four of these patients improved clinically after treatment but 1 has died. Collagenous sprue evolved on a background of CD in 4 cases. There was no history of CD in others and these cases may be the result of a biologic insult other than gluten sensitivity.
小肠活检表现为上皮下胶原沉积,绒毛萎缩程度不一,上皮内淋巴细胞浸润数量不等。4例患者以往曾做过活检,表现为其他肠病改变,并没有胶原沉积。7例患者合并胶原性结肠炎,且1例还有淋巴细胞性结肠炎的特征。3例患者胃活检也发现有胶原沉积。1例患者合并淋巴细胞性胃炎。4例患者有乳糜泻(CD,谷蛋白敏感性肠病)病史。5例患者经无麸质饮食和免疫抑制治疗后,临床症状有所改善。2例患者因营养不良合并另一种疾病而死亡。6例患者做了T细胞受体基因重排,其中5例发现有克隆性T细胞群,这5例中有4例治疗后临床症状加重,且1例死亡。4例患者在CD的基础上病发胶原性口炎性腹泻;其余患者无CD病史,他们的发病也许是生物源性损害,而非谷蛋白敏感。

AWARE that historically people have experienced these human rights violations because they are or are perceived to be lesbian, gay or bisexual, because of their consensual sexual conduct with persons of the same gender or because they are or are perceived to be transsexual, transgender or intersex or belong to social groups identified in particular societies by sexual orientation or gender identity
我们意识到:历史上,人们遭受这些违反人权的行为,是由於他们是或被认为是女同性恋、男同性恋或双性恋,由於他们与同性别的人进行双方自愿的性行为,或由於他们是或被认为是变性者、跨性别者或两性人,或属於在性倾向和性别认同上被认为是特殊群体的社会团体

With in situ DNA hybridization, the EBV genomes have been demonstrated in the labial glands of the Sjogren′s syndrome patients (16/28), moreover the elevated content of EBV DNA has been identified in those with more severe destruction of labial glands. It is concluded that EBV, vhich has a normal site of latency at salivary glands in a nonpathogenic state, may be reactivated in Sjogren′s syndrome patients and play a role in the pathogenesis of this disease.
另外,我们用原位杂交方法观察了EB病毒DNA在干燥综合征病人唇腺组织的存在状况,结果发现28例干燥综合征病人中16例为阳性,其中腺泡组织破坏严重者,EB病毒DNA的含量亦高,并且EB病毒主要分布于大量浸润的淋巴细胞中,其次位于腺泡上皮细胞内,少量见于腺泡腔中,以上结果提示,在干燥综合征病人EB病毒处于活跃的复制状态,干燥综合征病人靶器官受损与EB病毒的活跃复制及其诱导的免疫反应密切相关。

The spiny eel , belonging to Perciformes, Osteichthyes, is a kind of little freshwater fish distributed in Southern China. In 1998, Our lab detected XX/XY differentiated sex chromosomes in this specie with karyotypic analysis, and then with chromosomal binding and SC observation, we identified that its two largest metacentric chromosomes were X, Y sex chromosomes in 1999. X, Y chromosomes differ each other not only in the distribution of heterochromatin but also in their shapes, which make them could be recognized directly under the light-microscope without any banding treatment.
刺鳅,属鲈形目、刺鳅科(Perciformes,Mastacembelidae),是广泛分布于中国南方的小型淡水鱼类。1998年,我室通过核型分析,首次发现该物种具有明显分化的异形性染色体,其性别决定类型为XX/XY型。1999年,本室通过染色体显带、精母细胞联会复合体观察,再次确认刺鳅染色体组中最大的一对中部着丝粒染色体为X、Y性染色体,两者不仅已经出现结构异染色质分布上的不同,同时在外部形态上也存在明显差异,识别特征鲜明,在光镜观察下无需显带即能清晰辨认性染色体。

Oligoclonal expansion T cells could be detected and Vβ21 oligoclonal T cells were identified in all 3 cases.Conclusions The skew distribution and clonal expansion of TCR Vβ subfamily T cells could be found on the patients with CML.
结果 3例病人仅存在3~9个TCR Vβ亚家族T细胞,部分Vβ亚家族T细胞呈寡克隆性增殖,Vβ21的寡克隆T细胞见于全部的3例病人中。

With the help of its structure, this paper points out that the non-commutative finite solvable subsimple group will necessarily be a qualitative element group. And referring to the nature of qualitative element group, it can be easily identified the conditions that the ordered prime divisors in a solvable initial finite subsimple group should meet. Suppose that G is always a finite group.

The signals look like noncontinuous beads on the DNA fiber,which consist of multi-copy and arrange tandemly.Fiber-FISH results with 45S rDNA probe showed that an average signal length is about 3~11μm in many tandem copy sequence(measure number,n=8),so we estimated the size of each copy to be approximately 11~30kb in cotton genome.There are dual signals on each end of the mitosis metaphase chromosomes and pachytene chromosomes hybridized with telomere DNA probe.The signals also look like non-continuous beads on the DNA fiber,the length is about 1~9μm,so we estimated the size is about 4~27kb.The signals almost covered the whole mitosis metaphase chromosomes and pachytene chromosomes of G.arboretum Shixiya 1 hybridized with gDNA probe,the euchromatin zone and heterochromatin zone were identified clearly on pachytene chromosomes,and the signals also look like non-continuous beads.Two BAC clones 150-D-24 and 182-F-9 in DNA BAC library of Pima90 were selected as probe to hybridize with mitosis metaphase chromosomes,pachytene chromosomes and DNA fiber of G.raimondii.

Comparing with existing solutions, new method can utilize generators' speed signal measured by wide area measurement systems directly and detailed model and parameter of power system components were not needed. After sphering measurement-data, ICA with maximal negentropy criterion was carried out to obtain feature matrix. By this means high-dimension data of multi-machine perturbed trajectories were reduced to lower dimensions, and coherent generator groups were identified by pattern recognition consequently. Simulation results of 36-bus system with 8-generator and planning northwest China 750 kV power grid show that noise signals and bad data can be eliminated. This method is accurate in identifying coherent generator groups.
