Effects of poor glucose handling on arterial stiffness and left ventricular mass in normal children.

AIM: Cardiovascular risk factors can be present in children and young adults. We previously found abnormal microvascular function in children who had glucose intolerance and insulin resistance. The aim of the present study was to investigate whether they also have abnormalities in left ventricular mass (LVM) and arterial stiffness. METHODS: We measured heart dimensions and LVM using echocardiography, and arterial stiffness using pulse wave analysis in 23 children with good glucose handling (postfeeding glucose: 3.9 to 5 mmol/L) and 21 with poor glucose handling (7.7 to 11.4 mmol/L). RESULTS: The time to pulse reflection was slightly shorter in the poorer glucose handlers (mean+/-SD: 143+/-10 vs 153+/-20 ms, P=0.04), suggestive of increased arterial stiffness. Also in this group, there were significant relationships between intraventricular septal thickness, blood pressure and body mass index, but not in the normal glucose handlers. CONCLUSIONS: We have found that normal children who are in the lowest quintile of glucose tolerance in comparison with their peers are exhibiting the first signs of arterial stiffening. In addition, we have seen the beginnings of a relationship between blood pressure, body mass index and left ventricular enlargement in this group. While these changes may not yet be clinically significant, their emergence might be further evidence of early predisposition to cardiovascular disease.     

A double blind comparison of diclofenac and indomethacin in the treatment of ankylosing spondylitis

During almost 12 years of development and clinical trials, diclofenac sodium has been shown to be both effective and safe as a new nonsteroidal antiinflammatory drug (NSAID) for the treatment of rheumatic diseases including ankylosing spondylitis (AS). We compared the safety and efficacy of 75, 100, or 125 mg/day of diclofenac with the same doses of indomethacin in a multicenter, randomized, parallel group trial in patients with AS. A single blind placebo washout period of 2 days to 2 weeks preceded the 13-week double blind treatment period. Both diclofenac and indomethacin produced significant (p less than 0.001) improvement from baseline for all 14 efficacy variables analyzed. There were no significant between treatment differences. Differences favored diclofenac in the frequency and the severity of adverse experiences reported and in the frequency of complaints affecting the central nervous system.

《灵枢·官针》是关于中医古典针法的经典文献,其中所论刺痹法,内容丰富,手法多样,至今对临床仍有重要指导意义.刺痹法共有九种,毛刺法刺皮肤治浮痹,合谷刺刺肌肉治肌痹,恢刺与关刺刺筋腱治筋痹,输刺与短刺刺骨治疗骨痹.特殊操作类又有多针、多向刺法的齐刺、傍针刺和烧针刺法的焠刺,以治疗各种经久不愈的痹痛.研究这些古刺法,对于提高痹证的治疗效果,具有一定的指导意义.     

微创清除术治疗高血压脑出血35例的临床观察

目的观察应用微创清除术救治高血压脑出血的临床疗效。方法对68例高血压脑出血患者采用随机分成内科组(33例,采用控制血压治疗脑水肿等方法)和微创组(35例,采用微创清除术治疗)。采用格拉斯神经功能缺损评分量表及日常生活能力量表评分比较两组的近期(1个月)和远期(6个月)疗效。结果微创组近期优良率(60%)和远期良好率以上(70.3%)高于内科组(30.3%、46.2%%),差异有显著性(P<0.05,P<0.01);微创组近期死亡率(14.3%)明显低于内科组(54.5%),差异有显著性(P<0.01)。结论高血压脑出血采用微创清除术疗效优于内科治疗。     

Serpentine aneurysm of the posterior circulation: report of two cases

Giant serpentine aneurysms form a subgroup of giant intracranial aneurysms with specific radiological and surgical features. Previous reports have stressed the predilection of these lesions for the carotid circulation, particularly the middle cerebral artery. Two cases of serpentine aneurysm affecting the posterior circulation are reported and the problems of diagnosis and treatment of this lesion are discussed.     

Advanced colonic carcinoma in children.

We report two cases of colorectal carcinoma in children with a delay in diagnosis due to the low index of suspicion of this pathology as the cause of presenting symptoms. We conclude that any child presenting with unexplained rectal bleeding and abdominal pain should be investigated with endoscopy and barium enema.     

红细胞悬液中白细胞凋亡的研究

目的:研究低温和辐射对红细胞中残余自细胞凋亡及某些细胞因子水平的影响。方法：来自6名无偿献血者200ml全血分离制备悬浮红细胞，等份分装为10袋。除自身对照外均25Geyγ射线照射，然后置血库冰箱2℃-8℃保存。保存后3小时、2天、7天、14天和35天分别取样用化学法检测凋亡。保存期内第1、3、5周分别取样测定IL-1β、IL-6、IL-8和TNF-α含量。保存期末所有样品均进行血培养。结果：红细胞保存后第2天白细胞开始出现凋亡梯状条带，随时间延长而明显；对照组和照射组该持征条带差异不大，而两组的细胞因子含量都逐渐升高，且照射组升高幅度显著低于对照组；血培养呈阴性。结论：红细胞成分中的残余白细胞在体外低温环境下可发生凋亡。辐射可抑制体外成分血细胞因子增加，但辐射如何影响血液细胞的凋亡还有待进一步研究。
