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.     

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.     

眼球挫伤与锌

从１９９１年１１月到１９９２年８月对５０例眼挫伤的血清锌进行测定，３６例异常占７２％，其中有眼底改变占７５％。视神经视网膜挫伤锌值增高。低锌影响杆细胞及锥细胞代谢致视力低下，低锌影响视色素合成及色素上皮代谢，造成伤后视网膜色紊乱。     

石刻雕塑作业劳动卫生学调查及实验研究

测定了石雕作业粉尘浓度，几何平均浓度为８２．３５～３．６７ｍｇ／ｍ３。工人职业性健康检查结果，接尘工人的咽部充血、咳嗽、咯痰检出率高于对照组；肺功能低下的检出率也高于对照组。该厂自１９７２年以来发生尘肺患者１７例，其病情发展和晋期缓慢，发病工龄长。动物实验研究表明，石雕粉尘有轻微的致纤维化作用。     

传统腺样体切除术后腺样体残留情况调查

体统的腺样体手术为腺样体刮除术，为非直视下的手术，虽然多数患者手术后症状得得缓解，但临床上也常常看到手术后短时间内症状复发或者缓解不彻底的患儿，这类情况往往和腺样体手术切除不彻底有关。本院自2003年1月-2004年9月间对腺样体切除术后复发再次手术患者，以鼻内镜观察记录腺样体残留情况，对初次手术患者在进行传统腺样体刮除术并止血后，立即进行鼻内镜检查，了解腺样体残留情况并进行鼻内镜下处理，报告如下。     

ACTIVIT OF HUMAN PLACENTAL GAMMA GLOBULININ BLOCKING IMMUNE FUNCTIONS IN VITRO AND IN ABROGATING THE XENOGENEIC, LOCAL GRAFT-VERSUS-HOST-REEACTEON

In order to understand the mechanism of immunosuppression caused by infusion of placental gamma globulin (PGG) in patients with renal allografts, rheumatoid arthritis, and graft – versus –host disease (GCHD) following bone marrow transplantation (BMT) ,we have examined the effect of PGG in vitro and in a model of the xenogeneic , local graft –ver- sus – host reaction (LGVHR) .PGG inhibited lymphocyte proliferation in mixed lymphocyte cultures (MLC) (P<0.005) and depressed interleukin -2 (IL-2) levels in such cultures at 72 hours (P<0.01) . In contrast phytohemagglutinin (PHA) –and pokeweed mitogen (PWM) –induced T and B lymphocyte blastogenesis was not affected by such PGG treatment .PGG treatment .PGG neither decreased the [3H] TdR pulse incorporation in unstimulated lymphocytes nor affected cell viability .Cell cycle analysis by flow cytometry showed that PGG reduced the percentage of cells in S and G2, M phases during the MLC, but did not alter cell cycling during PWM-stimulated proliferation . An immunosuppressive effect of PGG on the LGCHR was tested in a model of intracutaneous transplantation of PGG –treat human lymphocytes into cyclophosphamide – immunosuppressed rats. Lymphoprep – separated human tonsillar lymphocytes were incubated with RPMI-1640 buffer containing：（1）PGG,4mg/ml,(2) human plasma albumin,4mg/ml,(3)mitomycin-C,25ug/ml, or (4) no additive. Cell of each preparation (3x107cells in 0.1ml) were injected intracutaneously into cyclophosphamide-treated male rats at separate abdominal locations. A fifth site received only the buffer solution. Five days after injection of cells ,each rat received [125 I]IUdR (10uCi) intraperitoneally and was killed after 5 hours. For each site of injection, the diameters of induration were measured and 125 I was counted . There was no difference between buffer – treated and a ibumin – treated groups either in the diameter of the area of induration (t=0.66;P>0.5)or in radioactive counts(t=0.22;P>0.05).In the PGG –treated group, the induration and radioactivity measurements were significantly less than in control groups (t=3.72 and P<0.1;t=2.62 and P<0.02,respectively ) Cytophilic antibodies in PGG were thought to inhibit an early phase of T cell activation, and not to be cytotoxicity .In the LGVHR, the immune response might be abrogated either by immuno- regulatory suppression of T cell function or by toxicity to the infused lymphoid cells. For some clinical purposes, immuno- modulating, human antibodies might be preferred to murine, monoclonal antibodies.
