Percutaneous transluminal coronary angioplasty in a patient with paroxysmal nocturnal hemoglobinuria

Paroxysmal nocturnal hemoglobinuria (PNH) is an acquired chronic hemolytic anemia associated with an unusual susceptibility to hemolytic crisis, infection, and venous thrombosis which would be aggravated by a number of factors including surgery. We report a case of PNH undergoing percutaneous transluminal coronary angioplasty and discuss the corresponding perioperative management.     

Diagnosis and management of obstetric acute disseminated intravascular coagulation]

Twenty-seven in-patients with obstetric DIC in our hospital from Jan. 1971 to Dec. 1990 were analysed retrospectively. The incidence was 0.12% in the first decade and 0.02%, in the second, showing a difference of significance between them. The most common predisposing factors included amniotic fluid embolism, abruptio placenta and hemorrhagic shock. Bleeding from multi-organs in various extent and coagulation disorders occurred in all those 27 cases. [Besides anti-shock treatment, heparin was employed together with fibrinogen in 4 postpartum and 1 antepartum DIC patients, fibrinogen alone in 8 cases, and hysterectomy in 11 cases. 17 patients were saved and 9 died. It is important that early diagnosis and much attention paid to clinical characteristics together with serial laboratory tests. Key management should include prompt treatment and eradication of predisposing factors. Quick decision spite of to terminate the pregnancy and even hysterectomy should be done in some risks.     

严重烫伤对睾丸间质细胞影响的实验研究

采用大鼠３０％Ⅲ度烫伤模型，应用光镜、电镜、３β－羟甾脱氢酶（３β－ＨＳＤ）组织化学染色及其相对活性的测定和血清睾酮及黄体生成素（ＬＨ）浓度的检测，分不同时相对严重烫伤后３０天内大鼠睾丸间质细胞的改变进行了动态观察。结果表明，烫伤后睾丸间质细胞有不同程度的变性、坏死；间质细胞内３β－ＨＳＤ活性迅速降低，伤后３０天仍保持较低水平；血清睾酮水平迅速下降，并持续维持较低水平，伤后３０天仍不回升，而血清ＬＨ浓度无明显改变。提示烫伤后血清睾酮下降的机理可能与睾丸间质细胞的受损及糖皮质激素升高有关。     

Effect of ibopamine and the active metabolite epinine on the catecholamine content of rat hypothalamus and brainstem in vitro

The effect of ibopamine (IBO) (SB 7505, SK&F 100168-A), a new drug for the treatment of congestive heart failure, and its active metabolite epinine (EPN) (N-methyldopamine), on the catecholamine content of hypothalamus and brainstem was studied in vitro after monoamine oxidase inhibition with pargyline. IBO and EPN increased levels of epinephrine (EPI) in a concentration- and time-dependent manner in both brain areas without significantly affecting the concentration of other catecholamines. Inhibition of either dopamine beta-hydroxylase, the neuronal EPI and norepinephrine uptake system, or esterase hydrolysis of IBO prevented the increase of EPI, whereas inhibition of phenylethanolamine N-methyltransferase, enzymatic dealkylation or the neuronal dopamine or serotonin uptake system had no influence on the increase of EPI levels. These results suggest that IBO after hydrolysis to EPN can be converted enzymatically to EPI by dopamine beta-hydroxylase in hypothalamus and brainstem. EPN seems to be accumulated into adrenergic and noradrenergic neurons by the high affinity uptake system. Changes in the EPI content of the central nervous system neurons might be responsible for some of the pharmacologic effects of IBO.     

中药治疗激素依赖性肾病综合征98例

肾病综合征是由多种病因引起的以大量蛋白尿、低蛋白血症、高度浮肿、高脂血症为临床特点的一组症状群，其基本病理缺陷是肾小球毛细血管基底膜通透性增加，属于中医“水肿”范畴。

目的　探讨医用创面封闭胶在减少肝切除术后肝断面渗血中的价值。方法　 2 0 0 2年 5～ 11月采用信封法将 60例接受肝切除术的病人随机分为医用胶组 (A组 ,n =3 0 )和对照组 (B组 ,n =3 0 )。A组在肝断面彻底止血后滴注医用创面封闭胶 ,B组则不用。测定术后第 1、2、3d腹腔引流液中红细胞 (RBC)数和血红蛋白 (Hb)量。结果　A、B两组术后腹腔引流液中的RBC数和Hb量均以第 1d为高峰 ,显著高于第 2、3d(P <0 0 5) ,其中A组术后第 1d腹腔引流液中RBC数及Hb量均显著低于B组 (P <0 0 5) ,只相当于B组第 2d的水平。A组主要并发症发生率低于B组 ,但差异无统计学意义 (P =0 0 7)。结论　医用创面封闭胶可有效抑制肝切除术后早期的肝断面渗血 ,有助于降低术后并发症的发生率     

Acupuncture at otoacupoint heart for treatment of vascular hypertension.

The immediate, short-term and long-term depressor effects, the immediate effects on cardiac functions in grade II and grade III vascular hypertension, and the effects on angiotensin II in grade III vascular hypertension by acupuncture at otoacupoint Heart were studied in 30 cases of vascular hypertensive patients. The immediate depressor effect of acupuncture at otoacupoint Stomach was also recorded for comparison. It was found that acupuncture at otoacupoint Heart produced marked immediate depressor effect, and the short-term effective rate was 100%, the long-term effective rate was 63.3%, as well as evident immediate effects on cardiac functional activities in grade II and grade III hypertension and marked effects on angiotensin II in grade III hypertension. Acupuncture at otoacupoint Stomach produced no depressor effect on vascular hypertension.     

小儿重肾31例分析

目的　探讨小儿重肾的诊断及治疗。方法　对我院 1989～ 2 0 0 1年收治的 3 1例小儿重肾进行回顾性分析。结果　 3 1例中有 2 3例患儿接受 2 6次手术 ,有 16例行上半重肾及输尿管切除 ,其中有 2例须处理输尿管残端及盲袋所致的梗阻。 2 2例手术后恢复较好 ,仅 1例伴有轻度的尿失禁。结论　对于重肾伴肾积水或发育不良所致的各种临床表现应首先考虑做上半肾及输尿管大部切除术。B超、CT及静脉肾盂造影术 (IVP)对诊断分型有意义。     

乐脂平治疗Ⅱ型糖尿病高脂血症的临床研究

观察了３０例伴有高脂血症的Ⅱ型糖尿病患者用小剂量乐脂平（５００ｍｇ／ｄ）治疗４周后血清脂质、脂蛋白的变化。结果：血总胆固醇、甘油三酯及极低密度脂蛋白—胆固醇水平较治疗前下降，高密度脂蛋白—胆固醇明显升高，血糖、血肌酐及血尿酸无明显变化。服用该药未观察到不良反应，提示乐脂平能较好地改善糖尿病患者的脂代谢紊乱。
