Diagnostic and prognostic value of the urinary excretion of beta-aminoisobutyric acid in patients with urinary bladder cancer

Urinary excretion of beta-aminoisobutyric acid (BAIB), was determined in 28 active and 12 inactive bladder cancer patients. Mean excretion of BAIB was higher in active cancer patients-187.8 mg/24 hours whereas it was 120.4 mg/24 hours in inactive cancer patients. The increased BAIB excretion in both disease groups was independent of tumour stage. BAIB appears to be a useful diagnositic aid in the assessment of bladder cancer patients.     

Dietary Habits of Greek Primary School Children

The purpose of this study was to assess Greek primary (1st to 6th grade) school children’s dietary habits and the factors influencing them. Our results show that children know the value of different foods. The socio-economic status of father has no effect on the attitude of children towards choosing their diet, however, mothers’ educational status appears to have an effect on their children’s behaviour. Place of residence (urban or semi-rural areas) and gender does not influence their knowledge about different diets. It was, finally, shown that as children grow older they tend to eat less healthy foods.

兔病毒性出血症和巴氏杆菌病灭活二联苗的研究与应用

用感染RVHD病兔的肝、脾、肾以及从鸡、兔混养暴发巴氏杆菌病兔体分离的细菌研制的甲醛灭活二联苗，免疫健康易感兔，于免疫后对RVHD强毒攻击第3天保护车达50％（6／12），第5天达100％（15／15），持续保护6个月以上，抗体动态测定与攻毒结果一致；对巴氏杆菌攻击第7、15天的保护率分别达75％（9／12）、91．7％（11／12）．6个月保护车仍达72．2％（13／18）。     

Understanding Greek Primary School Children's Comprehension of Sun Exposure

The purpose of this study was to assess Greek primary (1st to 6th grade) school children's understanding of sun exposure during summer vacation. Our results show that children know the damaging effects of long time exposure and the precautions that should be taken during sun bathing (sun glasses, hat, umbrella, sunscreen, etc). Nevertheless, they do not seem to avoid being exposed between 12.00 A.M. and 15.00 P.M., which is the most dangerous time. The socioeconomic status of father has no effect on the attitude of children towards taking protection measures when exposed to the sun, however, the educational status of the mother appears to influence children's reported knowledge and behaviour. Place of residence (urban or rural areas) and gender does not influence their knowledge on the sun's damaging effects and the precautions they should take. Finally, as children grow older they seem to gradually reduce the protective measures they take.     

Proteiomic patterns for endometrial cancer using SELDI-TOF-MS

Serum samples from endometrial cancer (EC) patients and healthy females were analyzed using surface-enhanced laser desorption-ionization time-of-flight mass spectrometry (SELDI-TOF-MS) to discover the potential diagnostic biomarker for detection of EC. A preliminary training set of spectra derived from 40 EC patients and 30 healthy women were used to develop a proteomic model that effectively discriminated cancer patients from healthy women. The training set had a specificity of 100% and sensitivity of 92.5% in the EC detection. A blind test set, including 20 new cancer cases and 10 healthy women, was used to validate the sensitivity and specificity of this multivariate model, which had a corresponding results of 60% in specificity and 75% in sensitivity, respectively. The combination of SELDI-TOF-MS with bioinformatics tools could help find new biomarkers and establish the detection of EC with high sensitivity and specificity.     

乳腺癌患者保留肋间臂神经的临床意义

目的：探讨乳腺癌腋窝淋巴结清扫术保留肋间臂神经的价值。方法：对天津医科大学附属肿瘤医院2000．1-2001．12月间69例保留肋间臂神经和34例切除肋间臂神经的乳腺癌患者进行随访。结果：肋间臂神经保留组术后48例无感觉方面上的变化，11例发生感觉麻木，1例上肢出现烧灼感，9例上肢出现感觉减退；而肋间臂神经切除组术后3例出现腋窝无汗．18例发生感觉麻木，4例上肢出现烧灼感，9例上肢出现感觉减退。两组之间在统计学上有显著性差异（x^2=48．1570；P〈0．05）；肋间臂神经保留组58例术后未发生患肢疼痛，11例发生患肢疼痛；而肋问臂神经切除组5例术后未发生患肢疼痛，29例术后发生患肢疼痛。两组患者之间在统计学上有显著性差异（x^2=46．1194；P〈0．05）。结论：乳腺癌患者保留肋间臂神经可以明显减少术后患侧上肢感觉障碍和疼痛的发生，从而提高患者的生活质量。     

Surgical management of gastric stump cancer： a report of 37 cases

Objective: To observe the clinicopathological characteristics of gastric stump cancer (GSC) and evaluate the benefits of radical surgery of GSC. Methods: The clinicopathological characteristics and postoperative survival time of 37 GSC patients who underwent surgery were investigated retrospectively. The survival time was compared according to the type of surgical pTMN stage. Survival curves were traced by using Kaplan-Meier methods. Results: Most GSC (32/37) was detected in patients who had received Billroth Ⅱ reconstruction after partial gastrectomy for benign gastric disease. The lesser curvature side and the suture line of anastomosis were the most frequent sites where GSC occurred (27/37). Differentiated adenocarcinoma was the dominant histopathological type (24/37). The postoperative 5-year survival rate of early stage GSC patients (n=9) was significantly higher than advanced stage GSC (n=12) (55.6% vs 16.5%, xL2=1 1.48, P＜0.01). Five-year survival rate of 21 GSC patients with radical resection were 75% (3/4) for stage Ⅰ, 60% (3/5) for stage Ⅱ, 14.2% (1/7) for stage Ⅲ, and 0% (0/5) for stage Ⅳ respectively.The median survival time of 21 GSC patients who underwent radical resection was longer than those undergoing palliative operation (43.0m vs 13.0m, xL2=36.31, P＜0.01), the median survival time of stage Ⅳ patients with radical resection was 23.8months. Conclusions: Without remote metastasis, radical resection for GSC is possible, and is an effective way to improve the prognosis of GSC. Even in stage Ⅳ GSC, radical resection can still prolong the survival time. It is necessary for the patients with benign gastric diseases who received partial gastrectomy to carry out the endoscopy follow-up, especially in patients with Billroth Ⅱ reconstruction procedure at 15-20 years.
