中药栀子超临界萃取物的挥发性成分研究

研究了栀子萃取的最佳工艺条件及其挥发油中的化学成分。以L9（3^4）正交设计对超临界萃取条件进行优化，GC-MS联用技术对挥发性成分进行定性及半定量分析。结果显示：55℃，35MPa，120min的萃取条件下挥发性成分的收率最高，超临界萃取产物的主要成分为亚油酸，棕榈酸，反，反-2，4-癸二烯醛，而传统水蒸汽蒸馏工艺下主要成分为反，反-2，4-癸二烯醛。与水蒸汽蒸馏工艺相比较。超临界流体萃取工艺且有革取率高。生产周期短的优点．

Failure of ivalon to provide permanent hepatic arterial occlusion

Ivalon (polyvinyl alcohol) is a commonly used embolic agent, generally considered to be permanent. In a patient with the carcinoid syndrome, embolization of hepatic metastases with Ivalon failed to produce permanent occlusion, and recurrent tumor was supplied by many of the same small arteries identified on the original arteriogram. Occasionally, Ivalon may have only a temporary occlusive effect. A possible explanation for this phenomenon is proposed.     

Flavocoxid is as effective as naproxen for managing the signs and symptoms of osteoarthritis of the knee in humans: a short-term randomized,double-blind pilot study

Flavocoxid (Limbrel), a proprietary mixture of flavonoid molecules (baicalin and catechin), was tested against a traditional nonsteroidal anti-inflammatory drug, naproxen, for the management of the signs and symptoms of moderate osteoarthritis (OA) in humans. Discomfort and global disease activity were used as the primary end points, and safety assessments were also taken for both treatments as a secondary endpoint. In this double-blind study, 103 subjects were randomly assigned to receive either flavocoxid [500 mg twice daily (BID)] or naproxen (500 mg BID) in a 1-month onset of action trial. Outcome measures included the short Western Ontario and McMaster University Osteoarthritis Index, subject Visual Analogue Scale for discomfort and global response, and investigator Visual Analogue Scale for global response and fecal occult blood. Both flavocoxid and naproxen showed significant reduction in the signs and symptoms of knee OA (P ≤ .001). There were no statistically detectable differences between the flavocoxid and naproxen groups with respect to any of the outcome variables. Similarly, there were no statistically detectable differences between the groups with respect to any adverse event, although there was a trend toward a higher incidence of edema and nonspecific musculoskeletal discomfort in the naproxen group. In this short-term pilot study, flavocoxid was as effective as naproxen in controlling the signs and symptoms of OA of the knee and would present a safe and effective option for those individuals on traditional nonsteroidal anti-inflammatory drugs or cyclooxygenase-2 inhibitors. A low incidence of adverse events was reported for both groups.     

Zolpidem induced nocturnal sleep‐related eating disorder (NSRED) in a male patient

Nocturnal Sleep‐Related Eating Disorder (NSRED) is a well‐documented sleeping disorder where the person is reported to experience bizarre eating behavior during sleep. Although various causes are implicated in this disorder, role of drugs cannot be ruled out. Here we narrate an interesting rare case report of a drug‐induced new onset NSRED, where a 45‐year‐old man on zolipdem performed an unexpected and bizarre eating behavior during somnambulistic state, type of which has not been reported earlier in the literature. The case falls under even rarer category as such behavior in sleep is reported mainly in woman. © 2008 by Wiley Periodicals, Inc. Int J Eat Disord 2009     

肿瘤转移相关蛋白在甲状腺乳头状腺癌伴淋巴结转移组织中的原位表达研究

利用免疫组化ＡＢＣ法，研究甲状腺乳头状腺癌，甲状腺腺瘤和正常甲状腺组织中的肿瘤转移相关基因蛋白ＣＤ４４ｖ６，ＥＧＦＲ，转移抑制基因ｎｍ２３－Ｈ１和抑癌基因ｐ５３蛋白的原位表达。结果发现ＣＤ４４ｖ６和ＥＧＦＲ表达上调与肿瘤转移密切相关（Ｐ＜０．０５，Ｐ＜０．０１），而ｎｍ２３－Ｈ１的表达与肿瘤转移抑制密切相关（Ｐ＜０．０１）。这提示肿瘤转移相关基因和转移抑制基因之间的表达失衡是甲状腺乳头状腺癌易发生转移的重要原因。
