从“治未病”思想探讨中医药防治EH相关子宫内膜癌的研究意义

子宫内膜癌为女性生殖道三大恶性肿瘤之一。子宫内膜增生症(endometrial hyperplasia,EH)乃子宫内膜癌的癌前病变,因而早期诊断和治疗EH非常必要。中医药防治EH相关子宫内膜癌有其应用简便、价格低廉、有效安全等优势,符合中医"治未病"的思想。由此推理,中医药防治EH相关子宫内膜癌有着广阔前景,值得深入研究。

目的 探讨乳腺癌术后皮下积液的防治方法。方法 回顾北京友谊医院普外科2002年1月～2004年12月收治的女性乳腺癌患者312例。比较皮下引流管接持续高负压吸引组（A组）与持续低负压引流组（B组），乳腺癌改良根治术后皮下积液的发生率。结果 A组160例患者拔管前合计引流量220～350ml，平均270ml。35例发生皮下积液，积液发生率为21．8％。同时伴皮瓣坏死5例。B组152例患者拔管前合计引流量160～250ml，平均180ml。17例发生皮下积液，积液发生率为11．2％。皮瓣坏死3例。B组与A组比较皮下积液发生率有显著性差异（P=0．011）。结论 乳腺癌改良根治术后引流管接持续低负压吸引有助于减少皮下积液的发生率。     

The impact of new screening protocol on individuals at increased risk of colorectal cancer

OBJECTIVE: Screening colonoscopy has been shown to reduce mortality and cancer stage in hereditary nonpolyposis colorectal cancer (HNPCC) individuals. However, the benefit of screening in intermediate risk groups is unknown. The most recent national guidelines have recommended a reduction of screening frequency for the intermediate risk group. Therefore, this study aims to compare the results of colonoscopic screening in HNPCC and intermediate risk groups and assess the effect of the most recent screening protocol recommendations. METHOD: A total of 244 individuals; 108 from HNPCC families (28 mismatch repair gene carriers) and 136 from intermediate risk families were referred for regular colonoscopic screening by the Regional Genetics Service. Findings from 417 colonoscopies performed between 1992 and 2003 were evaluated. RESULTS: A total of three cancers, 39 adenomas and 41 hyperplastic polyps were found in the HNPCC group compared with one cancer, 22 adenomas and 19 hyperplasic polyps in the intermediate risk group. If the recent screening guidelines for the intermediate group were applied, then 89 (44%) fewer colonoscopies would have been performed. Although no cancers would have been missed, six adenomas (mean size = 5.7 mm, range 2-10 mm) with two graded as severely dysplasic and six hyperplastic polyps would not have been detected. CONCLUSION: The detection rate and distribution of adenomas were similar in both groups. If the new colonoscopic screening recommendations for the intermediate risk group had been applied, a small number of significant lesions would have been missed.     

Using stories to battle unintentional injuries: Narratives in safety and health communication

After 14 years of rising death rates due to unintentional injuries in the U.S., it is time to ask how safety messages can be redesigned to have a greater impact on risky behavior. To this end, many researchers have called for a new, narrative approach to prevention messages—based on persuasive stories about people who have suffered injuries and illnesses in the past. Still, there is scant evidence that story-based communications are more effective than equivalent non-narrative messages at changing actual (rather than self-reported) safety and health behavior. Our research examined the impact of injury stories on actual safety behavior in a controlled experimental setting at a US university. Teams of participants assembled a product (a child's swing) using written instructions. The instructions contained safety messages targeting assembly mistakes that have been linked to serious injuries in children who play on swings. Participant teams were randomly assigned to three conditions: assembly instructions containing story-based safety messages, instructions with concrete (but non-anecdotal) safety messages, and instructions with traditional abstract safety messages. After adjustment for covariates, story-based messages resulted in a 19 percent improvement in safety behavior, compared with non-narrative communications. Importantly, injury stories did not create undue fear of the message object, demonstrating that brief anecdotes about accident victims can convince people to take reasonable precautions without creating unwarranted alarm about risks.     

利多卡因治疗外伤性蛛网膜下腔出血疗效分析

目的探讨早期静脉注射利多卡因对外伤性蛛网膜下腔出血（tsAH）继发性脑损伤的治疗作用。方法重度颅脑损伤后SAH患者60例（GCS评分≤8分）。随机分为治疗组（早期静脉注射利多卡因组）和对照组。在治疗前后对患者均进行GCS评分、颅内压（ICP）测定以及头部CT、发射计算机体层摄影（ECT）、经颅多普勒（TCD）检查。结果利多卡因治疗7d后即出现颅内压降低、挫伤脑组织血流供应改善、脑水肿减轻，与对照组比较，有明显差异（P〈0．01）；GCS评分在利多卡因治疗7d、14d后较对照组明显增加（P〈0．01）。结论早期静脉注射利多卡因能明显减轻颅脑损伤后SAH继发性脑组织损伤的程度，有利于神经功能的早期恢复。     

异位妊娠259例临床总结分析

Allergen avoidance in the secondary and tertiary prevention of allergic diseases: does it work?

Although allergen avoidance is widely recommended as part of a secondary and tertiary prevention strategy for allergic diseases, a clear-cut demonstration of its effectiveness is still lacking. Ongoing observational secondary prevention cohorts show that sensitisation to mite can be prevented in the short term by allergen avoidance measures, but further follow-up of these children is needed to show if this effect can be sustained, as well as to ascertain its impact on allergic disease. More well-designed trials are still required before we can give any conclusive advice to our patients. Considering the management of allergy, current evidence suggests that interventions in children (either single or multifaceted) may be associated with some beneficial effect on asthma control, but no conclusive evidence exists regarding rhinitis or eczema. Conversely, there is little evidence to support the recommendation of allergen avoidance methods in adults with asthma and rhinitis. There is a need for an adequately designed trial assessing the effects of a multifaceted intervention in this age group.
