上海市闵行区性病门诊本地和外来病人的比较研究

目的分析和比较上海市闵行区性病门诊本地与外来病人的流行病学特征。方法对2001~2004年上海市闵行区3家设有标准化性病门诊的公立医院进行门诊病历的回顾性分析。结果外来人口约占全部性病门诊病人的50%,其中女性病例占18.2%,未婚者占23.8%,均高于本地同类人员的比例;外来病人年龄偏低,多重感染者比例较高;男女外来病人与本地病人的首诊原因和症状排位相同,均以淋病感染为主;外来病人随访率(81.2%)较本地病人低(86.0%)。结论性病门诊本地和外来病人在人口学特征、诊疗行为上存在差异,防制措施应有所不同和侧重。     

Application of a pigment measuring device – Mexameter®– for the differential diagnosis of vitiligo and nevus depigmentosus

Background/purpose: Vitiligo and nevus depigmentosus (ND) present similar hypopigmented macules with significantly different prognoses. Although the distinction between the two diseases is important, differential diagnosis relies on medical history and physical examination, which is far from decisive in some cases. The Mexameter^® is an objective skin color-measuring device, and has been reported to provide a reproducible and sensitive means of quantifying small skin color differences. In this study, we investigated the usefulness of a Mexameter^® for discriminating these diseases.
Methods: A selection of 202 hypopigmented skin lesions (182 from vitiligo and 20 from ND) were the objects of this study. Using a Mexameter, MIs were obtained from lesions and symmetrically located control skin. RMIs, ratios of the MIs of lesional skins to control skins, were calculated.
Results: The mean MIs and RMIs were significantly different for vitiligo and ND. The mean RMI of ND lesions was 74±13, which was significantly higher than that of vitiligo lesions (50±24). No ND lesion had an RMI of <50%.
Conclusion: This study shows that the Mexameter^®, an objective pigment-measuring device, can be used to achieve a more accurate diagnosis of hypopigmentary disorders, and that the relative melanin index (RMI), which represents the relative pigment levels, might be a more effective parameter than the melanin index (MI) itself for comparing pigmentation differences.     

多疗程治疗的癌症病人入院时的焦虑状态调查

[目的]了解恶性肿瘤病人反复多次入院治疗时的心理状态,通过护理干预帮助病人更快投入治疗情境.[方法]通过焦虑自评量表(SAS)进行心理测验,随机将病人分为对照组和实验组,针对结果分别进行相应护理,1周后复查.[结果]实验组和对照组护理后的SAS评分差异显著.[结论]癌症病人多疗程入院的病人焦虑状况严重,实施焦虑的支持护理及心理辅助,可较好地促进病人进入治疗角色,减少弃治轻生的发生.     

AMPK在妊娠期糖尿病发病机制中的作用

腺苷酸活化蛋白激酶是一种重要的蛋白激酶,主要作用是协调代谢和能量平衡.腺苷酸活化蛋白激酶被激活后,在增加骨骼肌对葡萄糖摄取、增强胰岛素敏感性、增加脂肪酸氧化以及调节基因转录等方面发挥重要作用.已经证实脂联素有调节糖脂代谢的作用,但其作用机制尚不十分清楚,很可能是通过腺苷酸活化蛋白激酶介导,对脂联素信号转导通路的研究将成为进一步理解脂联素作用的关键所在.而脂联素又是妊娠期糖尿病的预测因子,所以腺苷酸活化蛋白激酶逐渐成为对妊娠期糖尿病研究中的焦点.     

D1期前列腺癌的诊断

１９９０年１２月至１９９３年１２月，我们对临床Ａ－Ｃ期２７例病人进行盆腔淋巴结活检术，检出１２例Ｄ１期病人。临床Ａ期有５０％，Ｂ期有３７％，Ｃ期有７１％的病人发现盆腔淋巴结癌转移，其癌细胞的恶性程度也与淋巴结癌转移有关。近年，经腹腔镜盆腔淋巴结活检已成为诊断Ｄ１期前列腺癌的新方法。     

Mid-trimester abortion using prostaglandin E2 gel.

Nineteen cases of mid-trimester pregnancy were terminated using prostaglandin E2 gel applied intracervically. In this prospective study, 42% were primipara with gestational age at the time of abortion between 16 and 28 weeks. The induction to abortion time was 19.65 +/- 10.37 h with a success rate of 89%. The average number of applications was 1.8 times (range 1-3 times) and the average dosage of prostaglandin required was 5.5 mg (range 3-9 mg). The complications were minimal except retained placenta in 42% of cases. Prostaglandin E2 in form of gel applied intracervically is an effective alternative to the commonly used hypertonic saline or, more recently, to prostaglandin analogues for termination of pregnancy in the second trimester.
