In the present work, the application of AgNOR count to differential diagnosis In 52 oases of cutaneous T cell lymphoma (CTCL) and 9 cases of cutaneous pseudolymphoma (CPL), Paraffin sections from 50 cases of mycosis fungoides (22 MF I-premycotio stage, 24 MF II-infiltrative stage and 4 MF III-tumor stage), 2 non-epidermal tropic cutaneous T cell lymphoma (NECTCL) and 9 CPL were investigated. The mean number, standard deviation and mean standard error of AgNOR counts were as follows: MF 11.17 ±0.09 SEM = 0.01; MF II 1.17 ± 0.01 SEM = 0.01;MFIII3.55±0.87SEM = 0.43; NECTCL 4.5±0.28 SEM = 0.19; CPL 1.17±0.1 SEM = 0.03. The results revealed a highly significant difference between CTCL (MF +NECTCL) and CPL (t=7.13; P<0.001), tumor stage and pretumor stage of mycosis fungoides (t=4.75; P<0.001). Thus, the AgNOR counb is valuable in differential diagnosis.

本文应用嗜银染色(AgNOR)计数对52例皮肤T细胞淋巴瘤(CTGL)及9例皮肤假性淋巴瘤(CPL)进行鉴别诊断。每例均在高倍油镜下随机计数200个细胞的AgNOR,并求得其平均数,标准差及均数标准误,结果如下:22例蕈样肉芽肿前期(MFI)为1.17±0.09SEM=0.01;24例蕈样肉芽肿浸润期(MFⅡ)为1.17±0.11 SEM 0.01;4例蕈样肉芽肿肿瘤期(MFⅢ)为3.55±0.87 SEM=0.43;2例非向表皮性皮肤T细胞淋巴瘤(NECTCL)为4.5±0.28 SEM=0.19;9例CPL为1.17±0.1 SEM=0.03。结果说明在CTCL(MFⅢ+NECTCL)与CPL之间(t=7.13;P<0.001)和MFⅠ与MFⅡ之间(t=4.75;P<0.001)AgNOR计数的差别是极为显著的。因此,AgNOR在鉴别诊断上是有价值的。

This paper presents measurements of 8 distances between several landmarks of the face and two indices of 3192 individuals of adolescents and children in Sichuan. The figure of the measurement between ectocanthion and otobasion superius and other 4 measurements are reported in this paper for the first time in China. There are significant sexual differences in most of the age groups. The distances increasing with age during growth are shown in the figures.

Objective To study the characteristic brain activation involved in attention in hypertension patients by performing the Simon task which is similar to stroop task, and by using event-related functional MRI (fMRI). Methods The study sample consisted of 2 groups: 12 stroke- and dementia-free hypertension patients aged 50 to 65 years, and 12 matched healthy old subjects. fMRI was scanned on a Sonata 1.5 T scanner (Siemens) while they were performing attention tasks.

Objective To study the characteristic brain activation involved in attention in hypertension patients by performing the Simon task which is similar to stroop task, and by using event-related functional MRI (fMRI). Methods The study sample consisted of 2 groups: 12 stroke- and dementia-free hypertension patients aged 50 to 65 years, and 12 matched healthy old subjects. fMRI was scanned on a Sonata 1.5 T scanner (Siemens) while they were performing attention tasks. The t-test was used to analyze the behavioral data between the two groups. Image data were motion corrected and spatially normalized according to the standard coordinates, and spatially smoothed with isotopic Guassian Kernel. Activation maps for attention conditions were generated respectively by deconvolve analysis. The general linear test was used to compare the cortex activation pattern and different active areas between tasks and groups. Results There were no significant differences between hypertension patients [(547±271) ms, (78±25)%] and control group [(529±321) ms, (89±8)%] in reaction times and accuracy when performing attention tasks (t=0.870, P=0.865;t=-1.597, P=0.121). But the standard error of mean of the patient′s accuracy rate(6.51) was significantly higher than that of the control group(2.22). Functional imaging data showed significantly greater activation in the patients compared with control group while performing the same task, especially in the prefrontal cortex (BA 6, 9, and 10). Conclusion fMRI appears to be more sensitive than neurological and neuropsychological evaluations in early hypertension-associated cognitive impairments.
