Transplantation of an eight-organ multivisceraI graft in a patient with frozen abdomen after complicated Crohn's disease

To report an extended multivisceral transplantation (MVTx) including right kidney and ascending colon in a patient with complicated Crohn's disease (CD). A 36-year old female suffering from short bowel syndrome and frozen abdomen due to fistulizing CD after multiple abdominal operations underwent MVTx of eight organs including stomach, pancreatoduodenal complex, liver, intestine, ascending colon, right kidney, right adrenal gland, and greater omentum in November 2003. Immunosuppression consisted of alemtuzumab, tacrolimus and steroids. The patient was off parenteral nutrition by postoperative wk 3. She experienced one episode of pneumonia. The patient recovered completely and discharged 2.5 mo and was doing well 30 mo after MVTx. This is one of the very rare cases in which a complete mulitivisceral graft of eight abdominal organs was transplanted orthotopically.     

前列腺癌根治术后性功能障碍：发生率、治疗、治疗局限性和苦恼

前列腺癌是北美地区男性最常见的恶性肿瘤之一，每年有215000新发病例，有35800例前列腺痛相关死亡。对于局限的前列腺癌，最常朋的治疗方法是前列腺癌根治术，10年生存率接近90％。研究表明，前列腺癌根治术后有44％-75％的患者有性功能障碍，〉60％的患者对此问题感到苦恼。作者检索了1966—2004年9月MEDLINE文献，对前列腺癌根治术后性功能障碍进行了综述。作者发现，尽管有效，但仍有30％-50％在前列腺癌根治术后寻求性功能辅助治疗的患者在1年内中断了治疗。说明尽管需要性功能辅助治疗，但对于长期的性功能适应仍然不够。     

Differential Effects of Anesthetics on Mitochondrial KATP Channel Activity and Cardiomyocyte Protection

Background: Mitochondrial adenosine triphosphate-sensitive potassium (mitoKATP) channels play a pivotal role in mediating cardiac preconditioning. The effects of intravenous anesthetics on this protective channel have not been investigated so far, but would be of importance with respect to experimental as well as clinical medicine.

Methods: Live cell microscopy was used to visualize and measure autofluorescence of flavoproteins, a direct reporter of mitoKATP channel activity, in response to the direct and highly selective mitoKATP channel opener diazoxide, or to diazoxide following exposure to various anesthetics commonly used in experimental and clinical medicine. A cellular model of ischemia with subsequent hypoosmolar trypan blue staining served to substantiate the effects of the anesthetics on mitoKATP channels with respect to myocyte viability.

Results: Diazoxide-induced mitoKATP channel opening was significantly inhibited by the anesthetics R-ketamine, and the barbiturates thiopental and pentobarbital. Conversely, urethane, 2,2,2-trichloroethanol (main metabolite of [alpha]-chloralose and chloral hydrate), and the opioid fentanyl potentiated the channel-opening effect of diazoxide, which was abrogated by coadministration of chelerythrine, a specific protein kinase C inhibitor. S-ketamine, propofol, xylazine, midazolam, and etomidate did not affect mitoKATP channel activity. The significance of these modulatory effects of the anesthetics on mitoKATP channel activity was substantiated in a cellular model of simulated ischemia, where diazoxide-induced cell protection was mitigated by R-ketamine and the barbiturates, while urethane, 2,2,2-trichloroethanol, and fentanyl potentiated myocyte protection.     

中医药治疗原发性肝癌110例临床观察

原发性肝癌是从肝细胞或肝内胆管细胞发生的癌肿,对放、化疗不敏感、病变发展快,死亡率较高、因肝功严重损害,癌组织侵入门静脉形成癌栓,导致门静脉高压,出现高度浮肿、大量腹水伴发上消化道出血,继发心肾损害、常出现肝昏迷,是我国九大恶性肿瘤之一。据国外统计,生存期仅为2.4～4.8个月。我们自1989年1月至1990年6年采用中医药免疫疗法治疗本病取得了一定的疗效,现报道如下:
