保圣寺藏清乾隆严氏祭田“执帖”碑

苏州甪直保圣寺藏有一方清代乾隆时期严氏祭田"执帖"碑,碑文主要涉及的是苏州甪直严氏祭田的由来,以及政府对义田的优免措施和破坏义田行为的量刑规定。这方碑刻是重要的地方社会史资料,对于研究清代苏州地方历史具有较高的学术价值,同时对研究清代禁碑的铭文制度也有重要意义。     

随刻入观追摹穷理——《石门铭》体察与随想

对《石门铭》随刻入观,就刻工虔诚与智慧,字形的虚空与环绕,字势的收与放等方面进行考察,力图对《石门铭》精神有一个更准确地把握。同时,围绕《石门铭》取法问题,论及对当下魏碑艺术运动的有关思考,认为其在拓展魏碑技法上确有贡献,但这仅仅是个出发点。清代碑学立足于上古精神的捕捉与笔法提炼,对现今魏碑探索仍具有十分重要的参照价值。

红枣山药蓝莓咀嚼片的研发及其免疫增强功能评价

以红枣、山药、蓝莓果粉为主要原料,辅以微晶纤维素、木糖醇和柠檬酸制备咀嚼片。通过单因素试验和响应面分析对产品配方进行优化,结果表明,红枣山药蓝莓咀嚼片的最佳配方为:红枣粉与山药粉添加质量比为2.5∶1(总量为10 g),蓝莓果粉添加量为10 g,微晶纤维素添加量为3.8 g,木糖醇添加量为0.3 g,柠檬酸添加量为0.09 g及0.5%硬脂酸镁,按该配方制得的咀嚼片外观光整,组织坚实、不松散、剖面紧密、不粘连,酸甜适中,无异味,无粗糙感,硬度适中,宜咀嚼。通过动物体内试验证实,产品可以有效延缓小鼠免疫器官的自然萎缩,提高小鼠体液免疫和细胞免疫,增强小鼠NK细胞活性,能够在一定程度上改善机体免疫功能。     

水温对磷化铝片剂产生磷化氢的影响

在实验室内用排集气法测定国产磷化铝片剂与水反应释放磷化氢进行实验。分别测定了10℃、20℃、30℃、40℃和50℃的水温下单片磷化铝片剂的产气量，并对不同水温下的产气量和产气速率进行了分析。结果表明，在30℃以下的水温条件下磷化铝片剂与水反应完全放出磷化氢需要比较长的时间，水温高于40℃时反应速率明显加快，水温高于50℃以后，在2小时左右片剂在水中基本上可以完全将磷化氢释放出来。     

复方蜂胶制剂对糖尿病小鼠糖耐量和肝糖原的影响研究

本文通过对一种蜂胶中药复方制剂，在小白鼠糖尿病模型，以高（3．60g／kg），中（2．00g／kg），低（0．80g/kg）三个剂量组灌胃的试验观察，探讨了复方蜂胶制剂对小鼠糖耐量和肝糖原的影响。结果显示：该蜂胶复方制剂可显著改善高血糖小鼠的糖耐量和增加高血糖小鼠的肝糖原含量，且比阳性对照优降糖组起效快，维持时间也较长。     

Thermal behaviour and biological activity against Aedes aegypti (Diptera: Culicidae) of permethrin and pyriproxyfen in a smoke‐generating formulation

BACKGROUND: The most common ways to control dengue vector Aedes aegypti (L.) are larval source reduction in domestic habitats and ground application of small quantities of aerosol insecticide (ultralow volume). Nevertheless, these actions have been shown repeatedly to be ineffective in controlling Ae. aegypti populations. RESULTS: The efficacy of a new smoke‐generating formulation containing pyriproxyfen and permethrin was evaluated in the laboratory. Smoke‐generating tablets containing each insecticide individually or combined were prepared, and the recovery of the insecticides from the smoke was determined. Recovery values of over 90% were obtained for pyriproxyfen, and around 50% for permethrin. The biological efficacy of pyriproxyfen released in the smoke was evaluated in the laboratory, on late third‐instar or early fourth‐instar Ae. aegypti larvae, using different concentrations of pyriproxyfen and exposure times. Adult emergence inhibition (EI) values of 100% were obtained at 30 min, and a dose‐dependent effect was observed at 5 min. The effect of pyriproxyfen released in the smoke was due to direct contact with the larvicide in the water rather than by inhalation of the fumes. The efficacy of permethrin released in the fumes was also evaluated as knockdown effect (KT₅₀) on adults for a tablet containing permethrin alone or permethrin plus pyriproxyfen. There was no significant difference in KT₅₀ values obtained for permethrin (KT₅₀ = 19.9 min) and permethrin plus pyriproxyfen (KT₅₀ = 19.4 min). CONCLUSION: The excellent laboratory performance of this new formulation on immature stages and adults indicates that a smoke‐generating tablet containing pyriproxyfen and permethrin could be a new tool for controlling mosquitoes.
