世界脊髓损伤研究的代表性方向

我们现在要尽量使这些治疗方法进入临床试验证明他们的可行性现在脊髓损伤的临床试验基金很有限，所以只有很少的这些治疗方法真正用于病人主要的制药厂开始对脊髓损伤治疗产生兴趣，我们现在还有很多工作要做，但是前景方向十分清楚，我们需要努力快速的工作。     

女性减肥者的体像问题与社会支持及性格的关系

目的研究女性减肥者的体像特征及相关因素。方法采用体像障碍自评量表、社会支持量表、艾森克个性问卷调查了100例减肥门诊女性就诊者，并与100例近5年无减肥经历女性对照。结果(1)女性减肥者，体像得分明显高于正常对照组。(2)女性减肥者的体像得分与收入、P分、N分明显正相关；与社会支持得分明显负相关，与BMI无相关性。结论女性减肥者，不管是否为单纯性肥胖，都存在较多的体像问题，且与特定得人格和社会支持有关。     

Expression of Anion Exchanger 1 Sequestrates p16 in the Cytoplasm in Gastric and Colonic Adenocarcinoma

p16^INK4A (p16) binds to cyclin-dependent kinase 4/6 and negatively regulates cell growth. Recent studies have led to an understanding of additional biologic functions for p16; however, the detailed mechanisms involved are still elusive. In this article, we show an unexpected expression of anion exchanger 1 (AE1) in the cytoplasm in poorly and moderately differentiated gastric and colonic adenocarcinoma cells and in its interaction with p16, thereby sequestrating the protein in the cytoplasm. Genetic alterations of p16 and AE1 were not detectable. Forced expression of AE1 in these cells sequestrated more p16 in the cytoplasm, whereas small interfering RNA-mediated silencing of AE1 in the cells induced the release of p16 from the cytoplasm to the nucleus, leading to cell death and growth inhibition of tumor cells. By analyzing tissue samples obtained from patients with gastric and colonic cancers, we found that 83.33% of gastric cancers and 56.52% of colonic cancers coexpressed AE1 and p16 in the cytoplasm. We conclude that AE1 plays a crucial role in the pathogenesis of gastric and colonic adenocarcinoma and that p16 dysfunction is a novel pathway of carcinogenesis.     

联合应用经腹腹膜前腹腔镜疝修补术和腹腔内网片植入术治疗成人腹股沟疝

目的联合应用经腹腹膜前腹腔镜疝修补术(transabdominal preperitoneal prosthetic,TAPP)和腹腔内网片植入术(intraperitoneal onlay mesh,IPOM),探讨理想的腹腔镜下腹股沟疝修补的方法。方法2006年1月~12月,对30例成人腹股沟疝行腹腔镜下修补。以腹壁下血管内侧缘为界,把疝薄弱区纵行分成内侧和外侧,内侧采用改进的TAPP方法,外侧仍用IPOM方法。沿腹壁下血管内侧缘纵行剪开腹膜后向内侧游离的区域内基本上是无血管区,亦无重要的神经,组织疏松极易游离,数分钟内即可分离出所需要的面积(7.5 cm×6.5 cm)。补片的材料亦分为内侧和外侧,内侧是聚丙烯材料,外侧应用Proceed补片。结果30例均在硬膜外麻醉下完成,手术时间单侧30~40 min,平均35 min,双侧50~60 min,平均55min,术中出血1~5 ml,术后第2天可离床活动,术后3~4天出院,术后2周均恢复工作。术后随访2~12个月,平均9个月,无粘连性肠梗阻,腹股沟部和全身无不良反应。结论联合应用TAPP和IPOM后,能体现微创的原则,易掌握,损伤少,手术时间短,恢复快,手术效果确切。     

Late atrioventricular block after heart transplantation.

Bradyarrhythmia requiring permanent pacing after heart transplantation remains a common problem. Sinus node dysfunction is the most common indication, and late onset of atrioventricular (AV) block has rarely been reported. We report the case of a patient who developed advanced AV block at 41 months after transplantation. Right bundle branch block with progressive increase of QRS complex duration was noted in serial electrocardiograms. At the time of late AV block development, the patient did not have acute rejection and coronary angiogram was normal. The mechanism of late onset of AV block is unclear, but it may be caused by progressive conduction.     

曼氏血吸虫与日本血吸虫交叉免疫原性的血清学实验研究

以曼氏血吸虫的虫卵和成虫免疫家兔后所产生的特异性抗体,可用以日本血吸虫虫卵、尾蚴和成虫为抗原分别进行的COP,CHR和ELACIEP测出,表明两种人体血吸虫存有显著的交叉抗原成分。应用此种血清交叉反应性,以检测抗异种人体血吸虫的抗体,似有效而可取的,可用以辅助诊断援外回国人员是否感染国外人体血吸虫病。     

《麦克白》主人公的悲剧心理

《麦克白》在现代莎评中自身几乎转换成了充满原型的心理悲剧，它在女巫、鬼魂、超自然因素及阴暗的色彩等笼罩下充分展示悲剧主人公的潜意识心理及其极力保持心灵内外对统一的平衡的努力；主人公本我狂野的欲望及其在事后的病态心理表现正是他们意识内外失控的心态，犹如进入黑夜的漫长旅程。     

识时度势保持特色力求发展--中西医合校的回顾与思考

新疆医科大学为全国第二家中西医合并院校.在新疆进行中西医合校,实属时势所使,事在必行.强弱相合,处于弱势的中医学院只有坚持相对独立,才能保证于合校后发扬中医药特色、办好中医药教育.中西医合校,给原本弱小的新疆高等中医药教育事业的发展带来了诸多可供凭借和利用的积极因素,同时也存在不少负面影响.新疆医科大学在实践中认清了中西医同校的优势与缺憾,采取扶持和爱护中医的策略,不断尝试规避冲突、化解矛盾、趋利祛弊、务期和谐,终喜事业有成,使高等中医药教育得以在新疆生存,并越过低谷,走上健康发展之路.     

Molecular determinants of cetuximab efficacy.

PURPOSE: To investigate whether mRNA expression levels of cyclin D1 (CCND1), cyclooxygenase 2 (Cox-2), epidermal growth factor receptor (EGFR), interleukin 8 (IL-8), and vascular endothelial growth factor (VEGF), all members of the EGFR signaling pathway, are associated with clinical outcome in patients with EGFR-expressing metastatic colorectal cancer (CRC) treated with cetuximab. PATIENTS AND METHODS: Thirty-nine patients with metastatic CRC, refractory to both irinotecan and oxaliplatin, were enrolled on IMCL-0144 and treated with single-agent cetuximab. The intratumoral mRNA levels of CCND1, Cox-2, EGFR, IL-8, and VEGF were assessed from paraffin-embedded tissue samples using laser-capture microdissection and quantitative real-time polymerase chain reaction. RESULTS: There were 21 women and 18 men with a median age of 64 years (range, 35 to 83 years). Higher gene expression levels of VEGF were associated with resistance to cetuximab (P = .038; Kruskal-Wallis test). The combination of low gene expression levels of Cox-2, EGFR, and IL-8 was significantly associated with overall survival (13.5 v 2.3 months; P = .028; log-rank test). Both findings were independent of skin toxicity that was itself significantly correlated to survival. Patients with a lower mRNA amount of EGFR had a longer overall survival compared with patients that had a higher mRNA amount (7.3 v 2.2 months; P = .09; log-rank test). Patients with lower expression of Cox-2 had a significantly higher rate of grade 2 to 3 skin reactions under cetuximab treatment. CONCLUSION: This pilot study suggests that gene expression levels of Cox-2, EGFR, IL-8, and VEGF in patients with metastatic CRC may be useful markers of clinical outcome in single-agent cetuximab treatment.
