Group coping skills training for anxiety and depression: its application with chronic patients

The literature on group coping skills training is reviewed and a model involving the use of a wide range of coping strategies with patients heterogeneous in terms of presenting problem is advocated. This study evaluates the effect of such an approach with a chronic inpatient and day-hospital patient population (n = 36) presenting with problems of anxiety and depression. Results suggest that the use of such groups can facilitate the transition from hospital to community. Further they are associated with symptomatic improvement that is of clinical significance in up to 50% of cases, which is largely maintained at 1 year follow-up and which is associated with a positive change in social functioning. In the light of this experience suggestions are made regarding the screening of patients and ways of enhancing group cohesion.     

Prostatectomy by transurethral balloon Laserthermia™ (PROSTALASE™) in the canine

Prostatectomy by transurethral balloon Laserthermia (PROSTA-LASE?) was performed in a canine model. This balloon device monitored by transrectal ultrasound can cylindrically irradiate with a laser beam. The treatment was performed in 8 canines using 15 watts for 20 minutes at 60°C at a 5 mm depth of the prostate from the urethral surface. Immediately following the laser therapy, an area of coagulation necrosis was observed around the urethra to a depth of 4–5 mm from the surface. After 1 week, cavitation formation was seen in 3 or 4 canines by ultrasound, and the urethral reepithelialization was shown in 1 of 2 canines. After 2 weeks, cavitation formation was observed in both canines, and the urethra was completely reepithelialized in one canine. There was no tissue damage in the bladder neck of urethral sphincter and no urinary incontinence in any animal. This system is thought to be simple and, satisfactorily performed, is an effective transurethral prostatectomy. © 1994 Wiley-Liss, Inc.     

Tumors of the skull base

Recognition of the many benign and malignant tumors that occur in the skull base is now simple, given three-dimensional CT scanning and MRI with enhancement. Recent developments in surgical technique have allowed these tumors to be approached, but only in the past two to three years has radical surgery been possible.     

广西武鸣华侨农场心血管病危险因素的调查研究

对广西武鸣华侨农场4158人进行基线普查,410人进行膳食调查和作8小时夜尿电解质测定,并将高血压低发区广西的资料与高发区的北京作对比.结果显示,体重指数高是高血压一个重要的危险因素,而体重过重又与膳食中摄入碳水化合物和总热量大有关.另一主要的危险因素是钠,膳食中摄入钠高,尿Na和Na/K比值高者,血压水平和高血压的患病率亦高.     

Gastric ulceration caused by heater probe coagulation

A double-contrast upper gastrointestinal examination on a woman who had undergone endoscopic heater probe therapy one day earlier for multiple arteriovenous malformations revealed shallow, irregular, and linear ulcers at the sites of heater probe coagulation. Multiple shallow ulcers may therefore develop as a direct complication of heater probe therapy. Radiologists should be aware of this complication to avoid diagnostic confusion in these patients.     

High-specificity in-situ hybridization. Methods and application.

We describe a technique of in-situ hybridization using oligonucleotide probes employing the expression of immunoglobulin VH genes as a model. Optimal conditions for hybridization with the 35S-labeled oligonucleotide probes were established with monoclonal B-cell lines that express VH genes of known nucleic acid sequence. The range of sensitivity and specificity achieved with this technique is documented. Under conditions of high stringency, this method can detect the expression of highly related VH hypervariable regions.     

Doppler assessment of the uterine circulation and the clinical behaviour of gestational trophoblastic tumours requiring chemotherapy.

The haemodynamics of the uterine arteries and myometrium were assessed using Doppler ultrasound in forty consecutive patients requiring treatment for invasive mole and choriocarcinoma. The investigations were performed prior to the commencement of chemotherapy and the subjects followed prospectively. The Doppler waveforms from the uterine arteries were analysed using the pulsatility index. It was found that patients with a pulsatility index of 1.1 or less were significantly more likely to develop drug resistance than those with a higher value (P < 0.04). There was no significant association between the pulsatility index and metastatic disease or uterine bleeding. Five out of eight patients who developed drug resistance could have avoided initial inadequate treatment if the Doppler findings were included in the scoring system for selecting chemotherapy for these tumours. It can be concluded that assessment of the uterine arteries using the pulsatility index prior to the treatment of patients with invasive mole and choriocarcinoma is of help in predicting those who will develop drug resistance.

Analysis of pancreas-infiltrating T cells in diabetic NOD mice: fusion with BW5147 yields a high frequency of islet-reactive hybridomas.

Diabetes in NOD mice is an autoimmune disease which is characterized by the infiltration of islets of Langerhans by large numbers of T cells. Some of these infiltrating T cells are clearly islet-cells-specific; however, many or most of these T cells could be attracted nonspecificity into these lesions. To study NOD pancreas-infiltrating T cells, we fused these cells with BW5147 to make T cell hybridomas. Ninety-four pancreas-derived T hybrids were analyzed of which 12 responded specifically to islet cells by secreting IL-2. Only CD3+, CD4+ hybrids responded to islet cells in our assay, and a large proportion of these hybrids were islet-cell reactive. T cell receptor (TCR) V beta element usage was heterogeneous in islet-reactive hybridomas.     

新疆哈萨克族常用食品对离体动物细胞染色体的损伤作用

本文报道以叙利亚地鼠胚胎(SHE)细胞和Wistar大鼠胚胎(WRE)细胞为靶细胞,运用体外姊妹染色单体交换试验、染色体畸变分析试验和微核试验检测哈萨克族(哈族)常用食品——烟熏肉和酸奶疙瘩对染色体的损伤作用。结果显示,烟熏肉和霉变酸奶疙瘩提取物均可明显增加SHE细胞姊妹染色单体交换频率和微核率,霉变酸奶疙瘩提取物亦可以使WRE细胞微核率显著升高(P<0.05);烟熏肉提取物还可明显诱导SHE细胞染色体畸变(P<0.05)。提示烟熏肉、霉变酸奶疙瘩中含有诱发动物细胞DNA损伤的致突变物质。
