由疫区医院SARS防治经验浅探突发性传染病防治模式

SARS暴发流行期间，疫区内医院面对复杂的社会环境、人群分布及致病原因不明、传染性强、传播途径不详、病情进展快、无特效治疗和收治条件有限等困难，通过健全疫情应急处理机制、启动卫生战备预案，按照管理传染源、切断传播途径、保护易感人群的方法，严格管理、科学治疗，取得了无院内交叉感染和无输入性病例发生的成绩，成功探索并实践了突发性传染病的防治模式。     

Impact of EGFR expression on colorectal cancer patient prognosis and survival.

BACKGROUND: Epidermal growth factor receptor (EGFR) is overexpressed in many types of cancers, especially colorectal cancer (CRC), and seems to reflect more aggressive histological and clinical behaviors. The aim of this study was to evaluate EGFR immunohistochemical reactivity in CRC biopsies, and to analyze its relationship with various histological and clinical characteristics and survival. PATIENTS AND METHODS: A composite EGFR score, obtained by multiplying the grade (% positive cells) by the intensity of labeling (0-9) was used to define patients with low or high EGFR expression whose clinicopathological features were then compared. Univariate tests and multivariate Cox proportional hazards model were applied for data analysis. RESULTS: Tissue sections from 150 CRC patients with a median follow-up of 40 months were examined. Median patient age at diagnosis was 70 years (range 38-89 years). EGFR reactivity was positive for 143 patients (97%) and high for 118 (80%). According to multivariate analysis, EGFR overexpression was significantly associated with tumor stage, with a higher percentage of EGFR overexpression in T3 than T4 (P=0.003) and not with overall survival. CONCLUSIONS: EGFR was overexpressed in this CRC patient population and was significantly associated with TNM (tumor-node-metastasis) stage T3. In the context of a new therapeutic strategy using EGFR-targeted therapies, although EGFR remains a controversial prognostic factor, this expression-stage association may play a crucial role in a decision to initiate an adjuvant treatment.     

Identification of RAD51–BRCA2 Inhibitors Using N-Acylhydrazone-Based Dynamic Combinatorial Chemistry

RAD51 is an ATP-dependent recombinase, recruited by BRCA2 to mediate DNA double-strand breaks repair through homologous recombination and represents an attractive cancer drug target. Herein, we applied for the first-time protein-templated dynamic combinatorial chemistry on RAD51 as a hit identification strategy. Upon design of N-acylhydrazone-based dynamic combinatorial libraries, RAD51 showed a clear templating effect, amplifying 19 N-acylhydrazones. Screening against the RAD51–BRCA2 protein–protein interaction via ELISA assay afforded 10 inhibitors in the micromolar range. Further ¹⁹F NMR experiments revealed that 7 could bind RAD51 and be displaced by BRC4, suggesting an interaction in the same binding pocket of BRCA2. These results proved not only that ptDCC could be successfully applied on full-length oligomeric RAD51, but also that it could address the need of alternative strategies toward the identification of small-molecule PPI inhibitors.

LSS法估算COPD患者茶碱缓释片单用及联用加替沙星时稳态药-时曲线下面积

目的用有限采样法（limited sampling strategy,LSS）估算慢性阻塞性肺疾病（COPD）患者单用茶碱缓释片及联用加替沙星时稳态药一时曲线下面积（AUC0-12^ss）。方法测得16名COPD患者口服茶碱缓释片稳态时（单用及联用加替沙星）的血药浓度,以多元线性回归法建立（AUC0-12^ss与不同时间点的血药浓度的关联数学模型,并用Jackknife法进行验证。结果单点预测时可以采用给药后2h或4h的血药浓度值预报药-时曲线下面积,单用茶碱回归方程为：AUC0-12^ss=-3．01＋11．15C2（R^2=0．97,P〈0．05）或AUC0-12^ss=-1．34＋10．91 C4（R^2=0．97,P〈0．05）。联用加替沙星的回归方程：AUC0-12^ss-3．14＋10．27 C2（R^2=0．90,P〈0．05）或AUC0-12^ss=-9．68＋11．74 C4（R^2=0．96,P〈0．05）。二点预测可用给药后2h及12h的血药浓度值,单用茶碱回归方程为：AUC0-12^ss=-0．28＋8．47 C2＋3．18 C12（R^2=0．98,P〈0．05）。联用加替沙星回归方程为：AUC0-12^ss=5．74＋3．64 C2＋8．54 C12（R^2=0．99．P〈0．05）。结论考虑到给药后2h为药物的达峰时间,推荐单点预测时用给药后2h的血药浓度值;用2个浓度点进行预测采用给药后2、12h的血药浓度值。
