美国应对流感大流行的抗病毒药物储备和使用策略

流感的大流行使抗流感病毒药物储备、药物使用策略制定和发布等应对措施显得极为重要。但多数国家的相关准备工作并不乐观。美国作为最重要的发达国家,其抗病毒药物储备和使用策略尤其引人关注并值得各国借鉴。     

我国乡村医生养老保障现状及对策

通过对乡村医生收入和养老保障的现状研究,发现乡村医生在现有体制和收入状态下难以实现养老保障。建议在全国范围内推广乡村医生养老保障制度,除政府增加投入外,还应考虑将乡村医生养老保险与现行养老保险制度合理接轨,明确乡镇卫生院作为上级监管负责单位的作用。     

增殖细胞核抗原与卵巢癌细胞系化学敏感性的关系

目的探讨增殖细胞核抗原(PCNA)与上皮性卵巢癌细胞系化学敏感性的关系.方法使用顺为铂作用于A2780及AD60细胞株.在MTT法测定耐药倍数基础上,用ABC检测PCNA表达.结果MTT测定MD60的耐药倍数为2.4.A2780 PCNA的表达低于AD60,且随药物浓度的递增染色较耐药组明显变浅.A2780、AD60相同药物浓度作用后PCNA的表达有显著性差异(P＜0.01);同一细胞株不同药物浓度作用后PCNA表达有显著性差异(P＜0.01).结论增殖细胞核抗原表达与上皮性卵巢癌细胞对细胞毒性药物的化学敏感性呈负相关.     

血清IgA-FN、Ⅳ型胶原在IgA肾病患者中的临床意义

目的　探讨IgA肾病患者血清IgA 纤维连接蛋白聚合物 (IgA FN)水平与其病理类型之间的关系及临床意义。方法　对 2 7例IgA肾病患者 ,根据肾脏组织病理学程度改变分为Ⅰ～Ⅲ级组、Ⅳ级组、Ⅴ级组。采用ELISA方法测定血清IgA FN、Ⅳ型胶原水平 ,并分析其与血肌酐、2 4小时尿蛋白定量和血压之间的关系。 结果　①血清IgA FN水平在Ⅳ级组最高 ,Ⅴ级组最低 (P <0 .0 5 ) ;②Ⅰ～Ⅲ级组、Ⅳ级组患者血清IgA FN与Ⅳ型胶原呈正相关性(r =0 .6 3,P <0 .0 5 ) ,与 2 4小时尿蛋白定量呈正相关 (r =0 .5 8,P <0 .0 5 ) ,Ⅴ级组二者无明显相关关系 ;③血清IgA FN水平与血肌酐水平和血压无相关性。 结论　IgA肾病患者血清IgA FN水平与IgA肾病病理严重程度有关 ,早期检测有助于早期诊断     

Autophagy & Phagocytosis in Neurological Disorders and their Possible Cross-talk

Autophagy and phagocytosis are two important endogenous lysosomal dependent clearing systems in the organism. In some neurological disorders, excessive autophagy or dysfunctional phagocytosis has been shown to contribute to brain injury. Recent studies have revealed that there are underlying interactions between these two processes. However, different studies show inconsistent results for the contribution of autophagy to the phagocytic process in diverse phagocytes and relatively little is known about the link between them especially in the brain. It is critical to understand the role that autophagy plays in phagocytic process in order to promote the clearance of endogenous and exogenous detrimental materials. In this review, we highlight the studies focusing on phagocytosis and autophagy occurring in the brain and summarizing the possible regulatory roles of autophagy in the process of phagocytosis. Balancing the roles of autophagy and phagocytosis may be a promising therapeutic strategy for the treatment of some neurological diseases in the future.     

The BNP to Albumin Ratio and Heart Rate in Stroke Complicating Atrial Fibrillation

Heart rate is still a controversial and unclear factor of stroke risk in atrial fibrillation. Indices combining parameters are more accurate predictors than single parameters. This article assessed the association of the BNP-to-albumin ratio (BAR), with the risk of stroke, and evaluated the relationship between heart rate and stroke risk. Data were retrospectively collected from the Zhongnan Hospital electronic records. Binary logistic regression assessed the association between BAR and the prediction of acute stroke in atrial fibrillation. Spearman's correlation analysis evaluated the correlation between heart rate and BAR. The specificity and sensitivity of the BAR index were determined by ROC curve analysis. A total of 197 participants were involved, including 119 cases and 78 controls. The mean BAR was significantly higher for cases than for controls P = 0.00 while the difference in mean heart rate did not reach statistical significance P = 0.08. Using binary logistic analysis, BAR was a significant predictor of stroke in AF, OR = 1.67 95%CI [1.09-2.55] P = 0.018. The correlation between BAR and heart rate was significant, the correlation coefficient was r = 0.15 P = 0.03. ROC curve analysis showed that at a cut-off value of 2.01*10-9 g/L 93% of patients with a BAR of less than 2.01 did not have an acute stroke and only the 60% with a BAR greater than 2.01 experienced an acute stroke. It's been suggested that the BNP to albumin ratio and heart rate could be used to estimate the risk of stroke among hospitalized atrial fibrillation patients, thus contributing to the implementation of appropriate measures.
