枸杞果柄对四氧嘧啶糖尿病小鼠血糖的影响

目的 探讨枸杞果柄水煎剂对四氧嘧啶糖尿病小鼠血糖的影响.方法 制备四氧嘧啶糖尿病小鼠模型,将其分为降糖灵治疗组、低剂量枸杞果柄治疗组、高剂量枸杞果柄治疗组、模型对照组,另设正常对照组(非糖尿病小鼠).前3组小鼠分别以25 mg·kg-1·d-1降糖灵水溶液、5.0 g·kg-1·d-1枸杞果柄水煎剂、7.5 g·kg-1·d-1枸杞果柄水煎剂灌胃,后2组小鼠均灌服等量的生理盐水.14 d后测定小鼠空腹血糖.结果 给药14 d后降糖灵治疗组、低剂量枸杞果柄治疗组小鼠血糖较治疗前有极显著下降(P<0.01),高剂量枸杞果柄治疗组小鼠血糖较治疗前有显著下降(P<0.05);降糖灵治疗组、不同剂量枸杞果柄治疗组血糖降低平均值与模型对照组、正常对照组血糖变化平均值之间均存在极显著差异(P<0.01).结论 一定剂量的枸杞果柄水煎剂对四氧嘧啶糖尿病小鼠血糖有降低作用.     

大鼠脑血肿周围组织STAT 3的表达、细胞凋亡的变化与CNTF的影响

目的 观察大鼠脑血肿周围组织STAT3, Bcl-2, Caspase-3的表达情况,并探讨睫状神经营养因子(CNTF)对出血性脑卒中的治疗作用及其可能机制.方法 实验大鼠随机分为假手术组、模型组、CNTF治疗组,采用自体股动脉血注入大鼠尾壳核建立脑出血模型,CNTF治疗组于术后经尾静脉注射CNTF.分别于术后12h、24h、3d、5d 4个时间点取脑组织,应用免疫组化方法检测血肿周围组织STAT3, Bcl-2, caspase-3的表达情况.结果 CNTF治疗组大鼠脑血肿周围组织STAT3, Bcl-2的表达明显高于其他组,Caspase-3的表达水平比模型组低.结论 CNTF对脑出血后损伤神经细胞具有保护作用,其可能的机制为通过上调STAT3的表达,使Bcl-2的表达升高,从而减少出血灶周围细胞的凋亡.     

Pediatric intracranial aneurysms—clinical characteristics and outcome of surgical treatment

Object Intracranial aneurysms are rare in children and have different epidemiological, clinical, and morphological characteristics and outcome from those in adults. Materials and methods We analyzed demographic, clinical, radiologic features, treatment, and outcome in 55 patients <18 years of age, treated from Jan 1995 through December 2005. Results Intracranial aneurysms in children below 18 years constituted 4% of all intracranial aneurysms. Internal Carotid artery (ICA) bifurcation was the commonest location. About half of the aneurysms were complex. Three-fourth of the patients required surgical treatment. Two patients died, constituting 5% mortality. Two patients (5%) had poor outcome, whereas the majority (90%) had a favorable outcome. Conclusions Pediatric aneurysms have male predominance, higher incidence of clinical features of mass effect or seizures, high incidence of large, traumatic/mycotic aneurysms, associated illnesses and ICH/IVH and hydrocephalus, better Hunt and Hess grades at presentation, ICA bifurcation as the commonest site, and better outcome than their adult counterparts.     

颅脑损伤患者上消化道出血的预防和治疗(附625例报告)

目的探讨颅脑损伤后上消化道出血的预防措施及其治疗方法。方法回顾性分析625例颅脑损伤后上消化道出血的病例,在治疗原发伤病基础上,采用止血、制酸、保护胃黏膜等对症处理,同时应用阿托品治疗22例;胃镜下治疗8例;胃次全切除术5例。结果本组病例中,治愈572例,缓解36例,无效5例,死亡12例,其中阿托品治愈20例;胃镜下治愈6例;胃次全切除术治愈4例。结论预防和治疗的重点是消除颅脑损伤病灶和保护胃黏膜,常规处理方案效果满意,简单、经济且安全有效,但必要时应及时使用特殊治疗手段,以迅速控制出血病情。

小脑后下动脉动脉瘤的诊断和治疗

目的探讨小脑后下动脉动脉瘤的临床特征、诊断、鉴别诊断和治疗。方法回顾性分析12例小脑后下动脉瘤的临床表现、影像学特征、手术效果及诊治过程中存在的相关问题。结果12例中有11例因动脉瘤破裂出血而发病,单纯第四脑室出血4例,全脑室系统出血2例,小脑半球出血3例,小脑蚓部伴第四脑室出血1例,侧脑室伴第三脑室出血1例,以后颅窝占位病变表现1例。8例术前行DSA检查明确诊断,4例术中明确诊断。12例均行后颅窝开颅显微手术治疗,其中动脉瘤颈夹闭9例,孤立切除2例,动脉瘤加固术1例,术后2例因脑积水加重行脑室-腹腔分流术。12例中除1例术后留有轻偏瘫外,其余11例恢复良好。结论小脑后下动脉瘤多以第四脑室出血发病,少数以小脑半球或蚓部出血发病,及早治疗效果满意。手术方式应尽量夹闭动脉瘤颈,对于小脑后下动脉末端动脉瘤,可以采用孤立切除术。     

Microalbuminuria in diabetes: relationships between urinary albumin excretion and diabetes-related variables

A single observer reviewed 842 of the 917 known diabetic patients registered with 40 GPs in the Poole area. Fifty-nine per cent (493) of those reviewed submitted a timed overnight urine collection to measure albumin excretion rate (AER) and overnight albumin/creatinine ratio (ON-Alb/Creat); 43 samples were excluded because of urinary tract infection and/or proteinuria. A random urine sample was obtained in 607 diabetic patients to measure the random albumin/creatinine ratio (R-Alb/Creat); 68 specimens were excluded because of infection and/or proteinuria, and in a further 10 samples urinary creatinine was not measured. Stepwise multiple regression analyses found significant associations with the following variables: for AER, blood glucose (p = 0.001), smoking category (p = 0.002), sex (p = 0.034), and systolic blood pressure (p = 0.035); for R-Alb/Creat, blood glucose (p = 0.001), retinopathy (p = 0.004), systolic blood pressure (p = 0.004), diastolic blood pressure (p = 0.015), coronary artery disease (p = 0.02), sex (p = 0.034), and vibration sense (p = 0.038). Interestingly, glycosylated haemoglobin was not a significant determinant of albuminuria in either analysis.
