头花蓼种子发芽生物学特性研究

目的研究头花蓼PolygonumcapitatumBuch.-Ham.exD.Don种子发芽的生物学特性。方法通过不同温度和黑暗条件下的发芽试验以及浸种处理发芽试验,观察统计其发芽所需时间、发芽持续时间、发芽势、发芽率。结果头花蓼种子在10～35℃下都能发芽;10～30℃下都能发芽完全;20℃、25℃时,观察的4项指标都无显著差异,并出现最短的发芽时间(4d)和最高发芽率(93.3%)。光照能使发芽时间缩短4天,发芽势提高50.6%,但不影响发芽率。浸种处理会降低头花蓼种子的发芽势和发芽率,特别是温水浸种达到极显著水平。结论20～25℃是头花蓼种子发芽的最适温度。发芽期间给予光照能极显著缩短发芽时间和提高发芽势。浸种处理对头花蓼种子的萌发没有促进作用。

海洛因依赖者与精神障碍的共病分析

目的:了解海洛因依赖者其它精神障碍的患病情况.方法:应用DSM-Ⅲ-R用定式临床检查手册和DSM-Ⅲ-R人格障碍用定式临床检查手册,调查了113名自愿戒毒的海洛因依赖者DSM-Ⅲ-R轴Ⅰ其它精神障碍和DSM-Ⅲ-R轴Ⅱ人格障碍的诊断情况.结果:心境障碍与物质滥用共患率较高.终生患病率55.7%,现患率60.2%.海洛因依赖者还伴有其它类型的精神活性物质使用障碍,终生患病率是59.2%,现患率是37.2%.轴Ⅱ人格障碍总患病率达到89.7%.边缘型人格障碍(61.7%)和强迫型人格障碍(58.5%)最常见,其次是偏执型人格障碍(52.1%).结论:自愿戒毒的海洛因依赖者中较多合并其它精神障碍.为了加强治疗效果预防复吸应更加关注共患疾病的诊断和治疗.

Primary tumors and mediastinal lymph nodes after neoadjuvant concurrent chemoradiotherapy of lung cancer: serial CT findings with pathologic correlation

PURPOSE: The purpose of this work was to describe the changes of primary tumor and mediastinal lymph nodes on CT after neoadjuvant concurrent chemoradiotherapy and to correlate the CT findings with pathology. METHOD: Twenty-one consecutive patients [N2 disease (n = 19) or resectable T4 and N2 disease (n = 2)] with non-small cell lung cancer underwent neoadjuvant concurrent chemoradiotherapy. Changes of primary tumor and mediastinal nodes before and after the therapy were assessed using CT. The CT findings were correlated with pathologic findings. RESULTS: With neoadjuvant therapy, decrease in T stage was achieved in 9 of 21 (43%) patients on CT. On pathology, the remaining tumor consisted mostly of fibrosis and necrosis with little proportion of viable tumor cells (mean volume 17%, range 0-55%). Decrease in nodal stage was achieved in 14 of 21 (67%) patients on pathologic examination. Seven patients had cancer cells in mediastinal lymph nodes: in 6 of 9 (67%) patients with adenocarcinoma and 1 of 12 (8%) patients with squamous cell carcinoma (p = 0.016). CONCLUSION: With neoadjuvant concurrent chemoradiotherapy, the remaining tumor consists mostly of fibrosis or necrosis. Decreased nodal stage on pathology is achieved especially in patients with N2 disease of squamous cell carcinoma. The CT findings of the tumor and mediastinal nodes are not helpful in predicting the pathology after the therapy.     

Fibrous dysplasia with barely increased uptake on bone scan: a case report

Fibrous dysplasia, in general, appears as an area of markedly increased uptake on bone scintigraphy. Therefore, the possibility of fibrous dysplasia is likely to be excluded when the lesion shows no or slightly increased uptake. The authors report a case of incidentally detected fibrous dysplasia that appeared as slightly increased uptake on bone scintigraphy and was found to harbor a bone infarction along with typical fibrous dysplasia by pathologic examination of a specimen sampled by curettage. Barely increased bone uptake in fibrous dysplasia may be associated with decreased vascularity and osteoblast activity of the lesion as a result of concurrent bone infarction. The authors suggest that not every case of fibrous dysplasia appears as an area of intensely increased uptake on a bone scan. Clinicians should be cautious in interpreting bone scans of radiographically indicated fibrous dysplasia.
