BUERGER'S DISEASE IN HONG KONG: A REVIEW OF 89 CASES

Background : A retrospective analysis of 103 case records from 1978 to 1996 with a provisional diagnosis of Buerger's disease was undertaken at the Department of Surgery, University of Hong Kong, Queen Mary Hospital. The aim of the study was to elucidate the clinical course and evaluate the results of surgical intervention of Buerger's disease in Hong Kong Chinese people. Methods : Fourteen patients were subsequently excluded from the study because of inability to fulfil our diagnostic criteria. Data on clinical presentation, investigations, indications and results of surgical intervention were reviewed. Sympathectomies and arterial reconstructions were performed on 42 and four patients, respectively, for critical ischaemia or rest pain. Outcome was analysed with respect to the rate of ulcer healing, pattern of recurrence and limb loss. Results : The patients were all young male heavy smokers with a mean age of 36.5 years. The majority of patients (80%) presented with ischaemic ulceration or gangrene. Vascular reconstruction was undertaken in four patients and satisfactory long-term results were obtained in three patients. Sympathectomy was able to relieve symptoms in 87% of operated patients and ischaemic ulceration healed in 2.6 (mean) ± 1.7 (SD) months after the operation. If the patient continued to smoke, surgical intervention did not exempt the patient from a relapse or amputation. Conclusion : Sympathectomy provides short-term pain relief and promotes ulcer healing in patients with Buerger's disease but carries no long-term benefit. Complete abstinence from smoking is the only means of arresting the progression of the disease.     

中草药红背丝绸不同成分对内皮素-1效应拮抗作用的研究

本文用中草药红背丝绸醇提物、乙酸乙脂提取物和单体ＣＡ－１２０１ 三种不同成分对ＥＴ－１ 在动物整体及离体水平生物学效应的拮抗作用进行了研究。结果发现：这三种成分对ＥＴ－１ 致小鼠进行死亡有保护作用，使得小鼠的死亡率及死亡数下降；并可拮抗ＥＴ－１ 致胸主动脉的缩血管效应，醇提物和乙酸乙脂提取物（１０－ ７母液）拮抗ＥＴ 缩血管效应分别为５７．２７％ 和５８．６１％ ；ＣＡ－１２０１ １０－ ８和１０－ ９ Ｍ 亦能拮抗ＥＴ－１ 的缩血管效应；醇提物和乙酸乙脂提取物口服及ＣＡ－１２０１ 静脉注射后能拮抗ＥＴ－１ 的升压作用，拮抗ＥＴ－１ 作用均呈现明显的剂量依赖性。提示中草药红背丝绸不同成分可拮抗ＥＴ－１ 的生物学效应。     

理气类中药对大鼠离体胃平滑肌条的作用

目的：观察理气类中药对大鼠离体胃平滑肌条运动的影响。方法：将肌条放置在灌流肌槽中，用生理记录仪记录肌条的收缩活动。结果：陈皮、枳实对胃各部位平滑肌条均为抑制效应，香附、薤白、木香、柿蒂、乌药对胃底肌条为兴奋效应，但对其他部位肌条则表现为兴奋或抑制不同的效应，沉香仅降低胃窦环行肌收缩波平均振幅，对其他肌条无影响。结论：理气类中药对大鼠离体胃平滑肌条既有兴奋作用，也有抑制作用。     

四种含淫羊藿中成药中淫羊藿甙的含量测定

The epidemiology of urinary dysfunction in Chinese women

The epidemiology of urinary dysfunction in a Chinese population living in Hong Kong was investigated. Fifteen hundred ethnic Chinese women answered a telephone questionnaire including symptoms of urinary dysfunction, anthropometric measurements, obstetric history and place of birth. The relative predictive value of these factors was analyzed using logistic regression. The prevalence of urinary dysfunction was 13%. Ten percent reported stress incontinence, and 4% had urgency or urge incontinence. The strongest predictor was place of birth, with women born in mainland China having the highest prevalence of pure stress incontinence (OR 1.33, CI 1.1–1.6). For the symptoms of detrusor instability age was the strongest predictor, with women over 50 years being at greater risk (OR 2.8, CI 1.6–5.0). Contrary to earlier beliefs, urinary dysfunction in Chinese women is as common as in Caucasian women. Place of birth is the strongest predictor for pure stress incontinence, with women born in mainland China being at greater risk. This suggests that environmental factors in early life have a differential effect on the development of urinary incontinence. EDITORIAL COMMENT: Taiwan Chinese women have a comparable prevalence of urinary dysfunction with Hong Kong Chinese women. A survey representing a multistage sample of 82 678 women aged 18 years or older was conducted in the Taipei area from January to June 1993. A total of 818 cases were interviewed by trained students. One hundred and eighty-nine (23.1%) of the respondents reported having had some degree of incontinence in the preceding 12 months, 28 (3.4%) reporting regular incontinence. Most presented with stress urinary incontinence, whereas urge incontinence and mixed incontinence were more commonly seen in the elderly group (aged 60 years or older). The risk factors for urinary incontinence included age, number of vaginal deliveries (>3), number of abortions (>2) and maternal history of incontinence. Voiding symptoms (irritative or obstructive) and constipation were significantly more prevalent among respondents with incontinence than those without (P<0.001). This evidence also indicates that the long-held belief that Chinese women have a much lower prevalence of urinary dysfunction than western women has all but ended.
