Tandem pore TWIK-related potassium channels and neuroprotection

TWIK-related potassium channels(TREK) belong to a subfamily of the two-pore domain potassium channels family with three members, TREK1, TREK2 and TWIK-related arachidonic acid-activated potassium channels. The two-pore domain potassium channels is the last big family of channels being discovered, therefore it is not surprising that most of the information we know about TREK channels predominantly comes from the study of heterologously expressed channels. Notwithstanding, in this review we pay special attention to the limited amount of information available on native TREK-like channels and real neurons in relation to neuroprotection. Mainly we focus on the role of free fatty acids, lysophospholipids and other neuroprotective agents like riluzole in the modulation of TREK channels, emphasizing on how important this modulation may be for the development of new therapies against neuropathic pain, depression, schizophrenia, epilepsy, ischemia and cardiac complications.

幼鼠内耳单个器官培养步骤及分类方法

内耳离体培养在研究内耳细胞功能、内耳组织发育再生、细胞损伤退化等方面具有重要价值。但由于内耳的组织结构微小复杂,其取材和培养具有较大难度,使该技术的普及和应用受到一定限制。本文在简要点评不同内耳离体培养方法优劣的基础上,结合本实验室多年来积累的实践经验,详细介绍了新生大鼠各个内耳终器取材及培养的具体步骤。从解剖迷路到分离终器,从凝胶制备到标本铺放,都有详细的操作指南,本文还针对各环节中的技术动作和关键事项进行了具体探讨并配以指导图例,希望这些内容能够弥补以往文献中抽象简略的条款式步骤所造成的实验困难,为开展内耳器官培养研究的初学者提供一定的帮助。     

卵巢子宫内膜异位囊肿粘连程度及相关因素分析

Objective To investigate the relationship between degree of endometrioma adhesions and clinical feature, surgical treatment and postoperative recurrence. Methods From Jan 2003 to Mar 2008, 662 patients with endometrioma undergoing laparoscopic ovarian endometrioma excision in Peking Union Medical College Hospital were studied retrospectively. All patients were classified into four groups according to the extent of adhesions: 31 cases in none adhesions group, 123 cases in mild adhesions group (filmy thickness, avascular, easily separated adhesions), 310 cases in moderate adhesions group (less than a half of ovary was adjacent to dense thickness adhesions which was difficult to separate, or above a half of ovary were adjacent to filmy thickness adhesions) and 198 cases in severe adhesions group (above a half of ovary was adjacent to dense thickness, well vascularized adhesions which was difficult to separate, and always involved the other pelvic organs, observed angiogenesis). The comparison of degree, characteristics, period of pain, lab test, surgical management and postoperative recurrence was performed among those above groups. In the mean time, risk factors and multinomial logistic regression were analyzed. Results (1)Clinical characteristics: The incidence of patients with dysmenorrhea, dyspareunia, straining feeling in anus, chronic pelvic pain and the level of CA125 (>35 kU/L) was remarkably higher in moderate-to-severe adhesion groups than in none-to-mild adhesions groups (P=0.000, 0.000, 0.001, 0.006 and 0.000, respectively). Infertility rate were significantly higher in severe adhesions group(15.7%,31/198) than none adhesions group(3.2%,1/31), mild adhesions group(11.4%,14/123) and moderate adhesions group(9.7%,30/310, OR=1.728, P<0.05).(2)Operating time and blood loss: Operating time of each groups was as followed: (37±15) min in none adhesions group, (42±19) min in mild adhesions group, (50±20) min in moderate adhesions group and (63±22) min in severe adhesion group. Blood loss was (23±12) ml in none adhesion group, (31±27) ml in mild adhesion group, (40±32) ml in moderate adhesion group and (70±67) ml in severe adhesions group. Thicker adhesions result in longer operation time and more blood loss. (3)Combined with other disease: The ratio of patients who combined with adenomyosis or deeply infiltrating endometriosis in moderate-to-severer adhesion groups was higher than patients in none-to-mild adhesions groups (OR=3.466, P=0.000). (4) Postoperative recurrence: It was categorized into recurrence of pain and cyst. Moderate-to-severe adhesions was related to higher recurrence rate of pain (OR=1.685,P=0.046), but was irrelevant to recurrence of cyst. Conclusion The more extent of endometrioma adhesions was related to severer pelvic pain symptoms, longer operating time and more blood loss. Postoperative pain recurrence rate was observed in moderate-to-severe adhesion group. Extent of adhesions was irrelevant to cyst recurrence.

慢性胰腺炎患者行包括临时支架的内镜下介入：一种有效的治疗

目的：过去15年在慢性胰腺炎（CP）的内镜治疗中取得了巨大进展。然而，经内镜行胰腺内放置支架的价值还有争议。材料与方法：对98例（84例男性，14例女性，年龄49±12岁，极差23～83）有症状的CP患进行包括胰管内临时支架的内镜下介入治疗。将最后支架取出时作为内镜治疗的主要研究终点，96例患共随访了35±28个月（极差8d～111个月），对所有数据进行回顾性分析。结果：与其他的内镜下操作一样，共有358个支架放置在胰管内且留置了3±1个月（极差1d～11个月）。总的支架治疗时间是10±10个月（极差6d～49个月）。在有限的内镜治疗后的46±27个月（极差4～111个月）中，57例患不需要再次介入治疗，甚至2／3患没有更多的疼痛感。在22例需要外科治疗和17例需要再次内镜治疗的患中明显与继续摄入乙醇有关。结论：临时支架植入作为CP患内镜介入治疗的一部分有较高的技术含量和长期临床成功率，而且在相当多患中不需要二次治疗。禁止乙醇摄入明显有助于治疗效果的维持。
