青海玉树健康人甲状腺激素测定

本文对玉树(海拔3700米)正常人58例的甲状腺激素用放射免疫法进行了测定,与西宁地区和平原地区对比,结果说明玉树地区T3、T4值明显或显著低于西宁和平原地区。TSH值又明显或显著高于西宁和平原地区、西宁地区P3、T4和TSH值均明显或显著低于平原。玉树地区藏、汉之间;男、女之间也有一定差异。这可能是高原低气压,缺氧对肝脏代谢的影响,调节甲状腺激素,以求机体对高原坏境的适应。     

Graves病患者血甲状旁腺激素、钙、磷、碱性磷酸酶基础值的观察

对照观察了28例Graves病患者及29名正常人血浆甲状旁腺激素、(PTH)血钙、血磷、碱性磷酸酶的基础值。Graves病组血碱性磷酸酶明显高于对照组,而PTH、钙、磷无显著差异。Graves病组血钙>2.75mmol/L者占21%,与某些文献大致相符。正常组血钙与PTH基础值间呈负相关,而Graves病组该两值间无相关,提示Graves病时血钙浓度的平衡调节中PTH以外的因素如甲状腺激素等可能对其影响较大。     

A case of polycythemia vera complicated by chronic renal failure under hemodialysis requiring parathyroidectomy for secondary hyperparathyroidisim

A case of polycythemia vera complicated by chronic renal failure under maintenance hemodialysis requiring parathyroidectory (PTH) for secondary hyperparathyroidism (2° HPT) is reported. A 62 year old female presented with 75000 white blood cells (WBC)/μl, 703×10⁴ red blood cells (RBC)/μl, 23×10⁴ platelets (PLT)/μl, hyperuricemia and hypertension in 1970 and the diagnosis of polycythemia vera was made. Hemodialysis was started in October 1974 for chronic renal failure. Blood cells in peripheral blood rapidly decreased in number after the beginning of dialysis, reaching the level of 10000∼20000 WBC/μl, and 150∼250×10⁴RBC/μl. In August 1988, marked bone resorption in X-ray picture and high serum alkaline phosphatase and parathyroid hormone (PTH) noted along with 17400 WBC/μl, 370×10⁴RBC/μl and 35.9×10⁴PLT/μl. After subtotal PTX removing 3.21g parathyroid gland, serum PTH rapidly fell. At 3 months after PTX, WBC rose to 23600/μl, RBC 372×10⁴/μl and PLT 94.0×10⁴/μl. At 6 months, WBC was to 31000/μl, RBC 429×10⁴/μl and PLT 78.0×10⁴/μl, suggesting an inhibitory action of PTH on not only RBC, but also WBC and PLT.     

Thyroid storm as a cause of loss of consciousness following anaesthesia for emergency Caesarean section

A previously undiagnosed thyrotoxic patient was anaesthetised for an emergency Caesarean section. The recovery period was complicated by an acute thyroid crisis resulting in loss of consciousness following an apparently normal recovery from general anaesthesia.     

血清保存方法对促甲状腺激素结果的影响观察

目的 :观察血清保存方法对促甲状腺激素 (TSH)结果的影响。方法 :将甲状腺功能正常、异常患者共 10份血清 ,采用不同血清量、不同条件分组保存后测定 TSH。结果 :保存方法对 TSH结果有一定的影响。结论 :用于 TSH血清的保存量要多、要密封管口、低温保存。     

生长激素在肝硬变门脉高压低蛋白血症手术前的应用研究

目的：研究生长激素（rhGH)对肝硬变门脉高压低蛋白血症患者手术前的治疗价值。方法：肝硬变门脉高压抑行脾切除、门奇静脉断流手术患者60例，Child分级B级，随机分为rhGH治疗组30例，对照组30例。rhGH组术前5d每天皮下注射rhGH 4IU，对照组给予安慰剂生理盐水。两组术前均行相同肠外营养支持。测定治疗前、治疗后3d、4d、5d血浆白蛋白、球蛋白、前白蛋白及空腹血糖。结果：rhGH组治疗后3d前白蛋白较治疗前及对照组明显升高（P＜0．05），治疗后4d、5d仍维持较高水平；治疗后5d白蛋白较治疗前及对照组明显升高（P＜0．05）。rhGH组患者一般情况改善，生活质量提高。对照组白蛋白、前白蛋白无明显变化。两组空腹血糖、球蛋白无明显改变。结论：rhGH联合肠外营养支持对纪正肝硬变门脉高压低蛋白血症患者术前低蛋白状态，改善生活质量有良好疗效，由于rhGH起效慢，应早期、足量、足疗程应用。     

硫代葡萄糖甙对碘代谢和甲状腺的影响

猪饲喂８％～１６％英籽饼日粮，平均每日从日粮中摄入９１９．４２～１４１６．０２ｍｇ硫代葡萄糖甙。在连续饲喂１２０天后，其甲状腺肿大，甲状腺滤泡和甲状腺上皮细胞显著增生，细胞质内缺乏分泌颗粒和溶酶体，细胞顶端密集微绒毛；滤泡腔内胶质周边部具有大量吸收空泡，分泌功能旺盛。Ｔ＿４和Ｔ＿４／Ｔ＿３比值明显升高，甲状腺功能亢进。若日粮中增加给碘量和服用解毒剂，猪甲状腺的组织形态学和超微结构接近正常，Ｔ＿４和／Ｔ＿４／Ｔ＿３比值亦趋于正常。     

Intermittent etidronate partially prevents bone loss in hirsute hyperandrogenic women treated with GnRH agonist

Treatment with gonadotropin-releasing hormone (GnRH) agonist leads to enhanced bone turnover and accelerated bone loss in premenopausal women with endometriosis, uterine leiomyomatomas and hirsutism. Sodium etidronate is a powerful inhibitor of bone resorption which has been proven efficacious in the prevention and treatment of postmenopausal osteoporosis. The objective of this study was to evaluate the skeletal effects of 6 months of therapy with the depot preparation of the GnRH agonist triptorelin (decapeptil 3.75 mg intramuscularly every 4 weeks) in 24 hirsute patients, aged 24–33 years, with hyperandrogenic chronic anovulation. Ten patients also received cyclical etidronate in an oral dose of 400 mg/day for 2 weeks, followed by an 11-week period of 500 mg/day elemental oral calcium (one cycle). The remaining 14 patients received 500 mg/day of elemental calcium continuously. After 6 months all treatments were discontinued for at least a further 6 months. Bone mineral density (BMD) at lumbar spine and hip (dual-energy X-ray absorptiometry, Sophos LXRA, France) and biochemical markers (serum alkaline phosphatase, osteocalcin, urinary N-telopeptide and hydroxyproline/creatinine ratio) were evaluated at baseline, 6 months and 12 months. In the group given GnRH agonist alone BMD fell significantly at all measured skeletal sites during the first 6 months. In the patients treated with etidronate a significant decrease in BMD was observed at lumbar spine but not in the femoral neck and trochanter, and the changes at lumbar spine and trochanter were significantly smaller than those in the control group. At 6 months bone turnover was also increased in patients treated with GnRH and calcium. Cyclical etidronate prevented the increase in biochemical markers of bone formation and resorption, with the exception of calcium/creatinine excretion, which was significantly increased in both groups. Six months after treatment withdrawal BMD did not recover in either group. Biochemical markers (N-telopeptide, serum alkaline phosphatase) remained increased in those patients previously treated with calcium alone while they remained close to baseline values in the patients treated with cyclical etidronate.Our study indicates that: (1) GnRH agonist therapy causes remarkable bone loss in young individuals with androgen excess who are expected to have increased bone mass; (2) this bone loss can be partially prevented by intermittent cyclical etidronate therapy.     

Ag—NOR计数在区分良恶性甲状腺病变中的意义

随机选择经长期随访证实的滤泡性甲状腺癌和腺瘤各10例,正常甲状腺组织5例作为对照。按Ploton的染色方法和Crocker推荐的计数方法分别计算三组每例各50个细胞的Ag-NOR嗜银颗粒平均数,再算出三组各自的AgNOR均数,经统计学检验三者有极显著性差异。可望成为甲状腺滤泡性肿瘤良恶鉴别的一项辅助指标。
