Pharmacist involvement in a thyroid clinic

The patient-care activities of a pharmacist in a thyroid clinic are described. Since 1978 a pharmacist has been an active member of the staff of a thyroid clinic associated with a 500-bed university hospital. More than 1500 patients are referred to the clinic each year. The pharmacist initiates, maintains, or modifies the drug therapy of selected patients with physician-diagnosed thyroid disorders under the guidance of written protocols approved by the chief endocrinologist. Most patients treated by the pharmacist are receiving thyroid-suppression therapy, antithyroid drugs for Graves' disease, or thyroid hormone supplementation after surgery or after radioactive iodine therapy. The pharmacist assesses patients, prescribes medications, orders laboratory tests, charts visits and therapeutic plans, and educates patients about their conditions. Major changes in thyroid status and drug therapy are always discussed with the chief endocrinologist. The pharmacist also participates in educational programs to influence prescribing by physicians, provides drug information, serves as a preceptor to pharmacy students, and is investigating the equivalence of levothyroxine preparations in vivo and in vitro. An audit of patient outcomes showed that the pharmacist is highly effective in her role as a giver of direct patient care. A pharmacist's role in a thyroid clinic can consist of clinical practice, education, preceptorship, and research.     

肿胀局麻技术的临床应用

目的探讨肿胀技术在体表外科手术中的应用价值。方法随机选择体表肿物与先天性畸形、体表瘢痕、乳房整形、脂肪抽吸、腹壁整形、除皱、隆胸、褥疮、面瘫及颅骨电烧伤等２３０例体表外科手术应用肿胀技术，成人１６４例，完全采用肿胀法局麻技术，儿童６６例，在全麻下应用肿胀技术。并与相应手术非肿胀法下施行进行了比较。结果脂肪抽吸术中利多卡因用量可达３０～６０ｍｇ／ｋｇ体重。肿胀技术具有易于进行解剖间隙的分离、减少术中失血、增强麻醉效果、增加手术安全性和术后恢复快等优点。结论肿胀技术可推广到体表外科手术中广泛应用，对儿童更为适宜，对减少输血造成的疾病具有重要意义。     

胃癌D17S261和D17S799位点二核苷酸重复序列不稳定性的意义

目的研究二核苷酸重复序列不稳定性〔ＤＲＳＩ〕在胃癌发生中的作用及其临床意义．方法采用ＰＣＲ方法检测了Ｄ１７Ｓ２６１和Ｄ１７Ｓ７９９位点二核苷酸重复序列不稳定性．结果胃癌总ＤＲＳＩ发生率为３４％（１７／５０），其中高中分化腺癌ＤＲＳＩ阳性率（６６７％，１０／１５）显著高于低分化癌（１９４％，６／３１，Ｐ＜００１）；肠型胃癌ＤＲＳＩ阳性率（５５６％，１０／１８）显著高于胃型胃癌（２０％，６／３０，Ｐ＜００５），ＤＲＳＩ与胃癌部位、大小、浸润、分期、淋巴结转移无显著相关．结论ＤＲＳＩ在胃癌的发生中可能起重要作用．     

Epoxyalkanoyls as novel ACE inhibitors

The epoxyalkanoyl derivatives were designed and synthesized as ACE inhibitors. Coupling of unsaturated carboxylic acids with amino acids and following epoxidation with dimethyldioxirane gave the epoxyalkanoyls with high yield. The inhibitory activity of synthesized compounds on angiotensin converting enzyme was IC₅₀ values of 0.06≈5.5 μM.     

脐血CD34^＋细胞免疫表型的分析

应用免疫磁珠法分离脐血ＣＤ３４＾＋细胞，以比较ＣＤ３４＾＋细胞亚群及各系相关抗原的变化。经过分离，ＣＤ３４＾＋细胞由１．４７±０．７７％升至５７．３９±１６．１７％，分离后ＣＤ３４＾＋ＣＤ３８＾－细胞占ＣＤ３４＾＋细胞的比率为７．８２±４．７９％ＣＤ３４＾＋。细胞纯化同时可减少ＣＤ３＾＋细胞达１４．１２±９．１８倍，ＣＤ１５＾＋细胞减少１６．４２±２１．４７倍；Ｂ系（ＣＤ１９）、巨核系（ＣＤ４１）     

SOD-like Activity of Copper Salicylate Complex in Tween Micel-lar Systems

合成了水杨酸铜络合物并分析了其组成，提纯了Ｔｗｅｅｎ－２０，－４０，－６０，－８０，并测定了它们在ｐＨ７．４的磷酸缓冲液中的ＣＭＣ。用Ｃｙｔ．ｃ还原法分别测定了水杨酸铜络合物在不同介质中的ＳＯＤ样活性。详细研究了表面活性剂与水杨酸铜络合物协同清除Ｏ－２的作用。观察到在胶束体系中水杨酸铜络合物的ＳＯＤ样活性明显高于缓冲液体系无表面活性剂时的ＳＯＤ样活性，表面活性剂本身也具有清除Ｏ－２的功能。抗红细胞膜脂质过氧化实验也得到类似结果。这可用胶束催化解释。水杨酸铜－Ｔｗｅｅｎ体系可能是一种潜在的抗炎药物。     

柴胡及甘草酸对小鼠肝细胞凋亡的影响

目的：研究柴胡（ＲＢ）及甘草酸（ＧＬ）对小鼠肝细胞凋亡的影响。方法：以肝／体重比，肝组织ＤＮＡ含量，组织学改变及原位凋亡细胞ＴＵＮＥＬ反应为指标，观察ＲＢ（１２．０ｇ／ｋｇ）及ＧＬ（５０ｍｇ／ｋｇ）ｉｐ，１次／８ｈ，对撇除苯巴比胺钠（ＰＢ）后引起的小鼠肝细胞凋亡的影响。结果：与对照组Ｃ相比，ＲＢ组小鼠肝／体重比及肝ＤＮＡ含量无明显回落，组织学检查未见明显凋亡改变，ＴＵＮＥＬ反应阴性，ＧＬ组小鼠肝／     

人子宫内膜植入兔眼前房模型的研究

本实验成功地将人子宫内膜植入到１５只去卵巢新西兰雌兔的眼前房，并给每只兔外源补充雌二醇（Ｅ２）１００μｇ／ｄ和孕酮（Ｐ）８ｍｇ／ｄ。在内膜植入期间每只兔皮下注射总量为９ｍｇ的霉酚酸（ｍｙ－ｃｏｐｈｅｎｏｌｉｃａｃｉｄ）以防免疫排斥反应。在眼前房的人子宫内膜存活了２８．４４±８．６５天，兔血清Ｅ２和Ｐ的平均值分别为１６１．７１±１５．１３和３８．８８±７．４５ｐｍｏｌ／Ｌ。前房液中Ｅ２和Ｐ浓度在植入人子宫内膜前后分别为２４．８０±１６．５３和１７０９．２５±４７５．１０ｐｍｏｌ／Ｌ，２．００±０．５３和１２．２２±３．８１ｎｍｏｌ／Ｌ。树脂切片验证人子宫内膜植入兔眼前房第５天就能与虹膜附贴并有血管发生。来自巩膜的血管分布在子宫内膜周围。扫描电镜观察人子宫内膜分化成分泌细胞和纤毛细胞。植入人子宫内膜后，前房液的蛋白浓度高于植入前。可以证明该模型可用来研究人子宫内膜对药物的反应和通过对前房液的测量研究子宫内膜的分泌功能。     

鱼油抗大鼠实验性心律失常作用

鱼油口服给药1.4 ml/kg·d,连续15d能显著升高氯化钡致大鼠心律失常的阈剂量(P<0.05),降低心律失常的严重程度(P<0.05),60 min内窦性心率恢复率为85.7％(P<0.01),死亡率为0。心肌细胞膜脂肪酸分析显示,鱼油影响大鼠心肌细胞膜脂肪酸组成,升高DHA含量(P<0.05),降低AA含量及AA/DHA比值(P<0.01)。多元逐步回归分析表明,鱼油的抗心律失常作用与其升高心肌细胞膜DHA含量有关,相关系数为r=-0.5872(P<0.01)。
