移植人羊膜细胞对大鼠创伤性脑损伤的实验研究

目的 探究大鼠TBI后脑内移植人羊膜细胞（HACs）对大鼠运动功能的影响。方法 HACs经分离、Hoechst33342标记后重悬调整细胞浓度为10^5/μl；采用改进的Feeney自由落体法打击大鼠脑皮层后肢运动区域，损伤后24h经微量注射器和立体定向仪将Hoechst33342标记的HACs 10μl分别移植于挫伤灶中心和挫伤灶边缘；在TBI后的28d内采用钉板平衡木行走测试大鼠运动功能变化，运动功能检测结束后取出脑组织行组织学检测。结果 治疗组滑落脚步数明显少于对照组（P〈0．05）；移植的HACs呈蓝色荧光；部分移植HACs可见MAP-2阳性表达。结论 移植HACs使大鼠TBI后运动功能明显改善。     

促血小板生成素对预测脑瘫高危儿的意义

目的探讨缺氧缺血性脑病(hypoxia-ischem ia encephalopathy,H IE)胎儿和H IE新生儿血清中促血小板生成素(Thrombopoietin,TPO)水平与脑损伤的关系,为脑瘫(cerebral palsy,CP)高危儿人群进行早期干预提供监测手段。方法收集23例H IE胎儿和34例H IE新生儿血清以及25例正常胎儿和30例正常新生儿血清,34例H IE新生儿包括11例轻度H IE,8例中度H IE和15例重度H IE。采用双抗体夹心ABC-ELISA法检测H IE胎儿组和轻、中、重H IE新生儿组血清中TPO的水平,并与正常胎儿组和正常新生儿组比较。结果H IE胎儿组和H IE新生儿组TPO分别高于正常胎儿组和正常新生儿组(分别P<0.01,P<0.01),重度H IE组TPO低于轻度H IE组(P<0.05)。结论血清TPO水平与H IE所致脑损伤严重程度有关。脐血TPO检测可为脑瘫高危儿人群进行早期干预提供监测手段。     

一种防脱出易制作义眼台的研制

目的探讨一种新型简易防脱出的义眼台的制作方法与效果。方法根据眼球摘除后的解剖特点设计义眼台大小,选择聚甲基丙烯酸甲酯和涤纶布为材料制作复合材料义眼台,并对6只家兔行眼球摘除后置入义眼台,经HE染色观察及肉眼观察术后不同时间置入物与眼周围组织的解剖关系。结果聚甲基丙烯酸甲酯部分与组织无黏连,涤纶布形成牢固黏连,周围有纤维组织长入并包绕,义眼台无脱出、移位。结论以聚甲基丙烯酸甲酯和涤纶布为材料制作复合义眼台,方法简易,效果可靠,组织相容性好,术后反应轻,值得在临床上推广使用。

2型糖尿病患者脂蛋白（a）水平、载脂蛋白（a）多态性和冠状动脉粥样硬化严重程度的关系

背景:针对糖尿病患者Lp(a)水平和冠状动脉疾病(CAD)严重程度之间关系的研究较少并且结论有争议。另外,目前尚无关于apo(a)多态性与上述疾病关系的研究。本研究旨在探讨大样本2型糖尿病患者中冠状动脉粥样硬化的程度与Lp(a)水平及apo(a)多态性的相关性。方法:连续选取227例2型糖     

The multiform and variable patterns of onset of orofacial granulomatosis

BACKGROUND: The recurrent chronic orofacial swelling caused by orofacial granulomatosis (OFG) can cause significant cosmetic and functional problems but can be prevented if the disease is diagnosed early and promptly treated. Although the enlargement of the lips is described to be the most common presenting complaint, the clinical onset of OFG may be characterized by minor associated mucosal and neurological manifestations, making early diagnosis very difficult or, sometimes, merely presumable. PATIENTS AND METHODS: We retrospectively analyzed the clinical manifestations of 19 patients with OFG, who were examined at our institution between 1998 and 2002, in order to determine their initial manifestations and presenting symptoms. RESULTS: A total of 10 patients showed classical recurrent enlargement of the lips (six lower; four upper) as presenting symptom. In the other nine patients, OFG onset was characterized by transient unilateral facial nerve palsy (two cases), intraoral manifestations (two cases), recurrent swelling of the periorbital area (two cases), of the chin (one case), of the zygomatic area (one case), and of the cheeks (one case). CONCLUSION: Our data underlined that OFG onset could be frequently characterized by widely variable, multiform, and temporary clinical findings. Involvement of atypical sites of the orofacial region and presence of single minor manifestations may occur as presenting symptoms, often preceding the development of traditional clinical findings.     

The finding of the nematode Daniconema anguillae Moravec et Køie, 1987 (Spirurida, Dracunculoidea: Daniconematidae) in Lithuania

Summary The third-stage larvae of Daniconema anguillae Moravec et K?ie, 1987 are found in the eels fins caught from Dringis Lake (Lithuanian National park). The morphology of these larvae is briefly described.     

A Preliminary Study of Negative Self-Beliefs in Anorexia Nervosa: A Detailed Exploration of Their Content, Origins and Functional Links to “Not Eating Enough” and Other Characteristic Behaviors

Objective: The study explored the semantic content and origins of negative self-beliefs, and their functional links to “not eating enough” and other behaviors, in participants with anorexia nervosa (AN). Method: Fifteen women meeting DSM-IV criteria for AN were compared with 17 dieting and 18 non-dieting women matched on age and number of years of education. The main outcome measure was a semi-structured interview. Results: Six themes were identified in the beliefs of participants with AN. These were, in order of decreasing frequency, powerlessness (present in all but three AN participants), failure, defectiveness, unattractiveness, worthlessness and emptiness. Importantly, powerlessness and failure beliefs were consistently present independent of Beck Depression Inventory-II scores. The negative early life experiences associated with these beliefs had high distress and responsibility ratings. Participants with AN reported that they employed specific behaviors, particularly ‘not eating enough,’ and ‘placating others,’ to try to reduce the cognitive and emotional impact of their negative self-beliefs. Discussion: The findings are discussed in relation to the role of powerlessness and the function of “not eating enough” in cognitive theory and therapy for AN.
