目的：比较胃溃疡与溃疡型胃癌的发病特点。方法：对69例胃溃疡与32例胃癌进行回顾性分析，比较二者好发年龄、胃镜下变病部位和大小的差异。结果：63.7%胃溃疡多发生于50岁以下患者，81.3%胃癌发生于50岁以上患者（Ｐ＜0.01）。贲门部的胃癌是胃溃疡的5倍（Ｐ＜0.01）；胃角部的胃溃疡是胃癌的9倍（Ｐ＜0.01）；溃疡型胃癌与胃溃疡都易发生在胃窦，且检出率相似。82.6%胃溃疡直径＜3 cm，78.1%胃癌直径≥3 cm（Ｐ＜0.01）。结论：胃溃疡与溃疡型胃癌的好发年龄、生长部位和大小几乎各不相同，这些发病特点对溃疡型胃癌的早期诊断有一定指导意义。
Objective To elucidate the effect of first-aid fast track in triaging earthquake trauma patients by studying the earthquake trauma patients staying in the Emergency Department of West China Hospital after “5•12 Wenchuan Earthquake” so as to accumulate experience in the treatment of disaster traumas. Methods A retrospective study was done on earthquake trauma patients staying in the Emergency Department of West China Hospital after “5•12 Wenchuan Earthquake” from 14:28 May 12, 2008 to 14:27 May 15, 2008. Differences in care given during the time period were analyzed. Results There were 536 earthquake trauma patients in West China Hospital within 72 hours after the earthquake. Twohundred and seven earthquake trauma patients staying in the Emergency Department had an average stay of 129 minutes during the 24 hours after the quake; 104 earthquake trauma patients staying in the Emergency Department had an average stay of 97 minutes in the second 24 hours; and 226 earthquake trauma patients staying in the Emergency Department had an average stay of 86 minutes in the third 24 hours. Each consecutive day showed shorter average stays. Conclusion The first-aid fast track not only guarantees earthquake trauma patients are saved as soon as possible but also shortens the time in the Emergency Department.
Individuals with motor dysfunction caused by damage to the central nervous system are unable to transmit voluntary movement commands to their muscles, resulting in a reduced ability to control their limbs. However, traditional rehabilitation methods have problems such as long treatment cycles and high labor costs. Functional electrical stimulation (FES) based on brain-computer interface (BCI) connects the patient’s intentions with muscle contraction, and helps to promote the reconstruction of nerve function by recognizing nerve signals and stimulating the moving muscle group with electrical impulses to produce muscle convulsions or limb movements. It is an effective treatment for sequelae of neurological diseases such as stroke and spinal cord injury. This article reviewed the current research status of BCI-based FES from three aspects: BCI paradigms, FES parameters and rehabilitation efficacy, and looked forward to the future development trend of this technology, in order to improve the understanding of BCI-based FES.
