波动性高糖对内皮细胞自噬基因表达的影响

【目的】探讨波动性高糖对内皮细胞自噬的影响及其可能的机制。【方法】体外培养人脐静脉内皮细胞(human umbilical vein endothelial cells,HUVEC)用于实验。实验分正常对照组(5.5 mmol/L葡萄糖)和葡萄糖交替处理组(5.5/28 mmol/L葡萄糖)。其中葡萄糖交替处理模拟人血糖波动状态,方案是前12 h内每隔4 h交替培养,后12 h内葡萄糖维持5.5 mmol/L水平,按此循环,共培养48 h。用CCK-8检测细胞活性,酶标仪检测氧化应激相关指标,实时荧光定量PCR检测自噬相关基因的表达情况。【结果】与正常对照组相比,葡萄糖交替处理组降低HUVEC细胞活性(P<0.01);降低细胞内抗氧化酶活性,增加丙二醛和8-羟基脱氧鸟苷的含量(P<0.01);增加自噬相关基因Atg4和Atg5的表达(P<0.001)。【结论】波动性高糖可能是先通过诱导HUVEC产生氧化应激,进而使HUVEC产生自噬,最终降低细胞活性。     

卵巢子宫内膜异位囊肿粘连程度及相关因素分析

Objective To investigate the relationship between degree of endometrioma adhesions and clinical feature, surgical treatment and postoperative recurrence. Methods From Jan 2003 to Mar 2008, 662 patients with endometrioma undergoing laparoscopic ovarian endometrioma excision in Peking Union Medical College Hospital were studied retrospectively. All patients were classified into four groups according to the extent of adhesions: 31 cases in none adhesions group, 123 cases in mild adhesions group (filmy thickness, avascular, easily separated adhesions), 310 cases in moderate adhesions group (less than a half of ovary was adjacent to dense thickness adhesions which was difficult to separate, or above a half of ovary were adjacent to filmy thickness adhesions) and 198 cases in severe adhesions group (above a half of ovary was adjacent to dense thickness, well vascularized adhesions which was difficult to separate, and always involved the other pelvic organs, observed angiogenesis). The comparison of degree, characteristics, period of pain, lab test, surgical management and postoperative recurrence was performed among those above groups. In the mean time, risk factors and multinomial logistic regression were analyzed. Results (1)Clinical characteristics: The incidence of patients with dysmenorrhea, dyspareunia, straining feeling in anus, chronic pelvic pain and the level of CA125 (>35 kU/L) was remarkably higher in moderate-to-severe adhesion groups than in none-to-mild adhesions groups (P=0.000, 0.000, 0.001, 0.006 and 0.000, respectively). Infertility rate were significantly higher in severe adhesions group(15.7%,31/198) than none adhesions group(3.2%,1/31), mild adhesions group(11.4%,14/123) and moderate adhesions group(9.7%,30/310, OR=1.728, P<0.05).(2)Operating time and blood loss: Operating time of each groups was as followed: (37±15) min in none adhesions group, (42±19) min in mild adhesions group, (50±20) min in moderate adhesions group and (63±22) min in severe adhesion group. Blood loss was (23±12) ml in none adhesion group, (31±27) ml in mild adhesion group, (40±32) ml in moderate adhesion group and (70±67) ml in severe adhesions group. Thicker adhesions result in longer operation time and more blood loss. (3)Combined with other disease: The ratio of patients who combined with adenomyosis or deeply infiltrating endometriosis in moderate-to-severer adhesion groups was higher than patients in none-to-mild adhesions groups (OR=3.466, P=0.000). (4) Postoperative recurrence: It was categorized into recurrence of pain and cyst. Moderate-to-severe adhesions was related to higher recurrence rate of pain (OR=1.685,P=0.046), but was irrelevant to recurrence of cyst. Conclusion The more extent of endometrioma adhesions was related to severer pelvic pain symptoms, longer operating time and more blood loss. Postoperative pain recurrence rate was observed in moderate-to-severe adhesion group. Extent of adhesions was irrelevant to cyst recurrence.     

舶来的"四泉利润"

“做个加盟店很不划算，交加盟费、风险金，还要给特许商管理费……”，许多意向加盟商都有这种说法。有些特许商也常说：“开上几十家店，加盟费都赚不过来，自已还可以直营，还有管理费、促销费、培训费……”这正应了“羊毛出在羊身上”这句古话。     

脊髓室管膜瘤的显微外科治疗

我院自1995年以来收治了36例脊髓室管膜瘤患者，占同期脊髓髓内肿瘤的33．6％；本组患者均采用了显微外科手术治疗，取得了比较满意的疗效。     

魅力眼睛有八法

眼睛与其它器官一样,随着年龄的增长或因其它疾病影响会逐渐退化和衰弱。如何养目来增进健康呢?根据我国传统的养目方法,结合现代医学有关知识,可归纳出八种养目方法。熨目每天晨起或睡前,取坐或立式,闭目,同时双手掌快速摩擦揉搓,约半分钟便会感到发热发烫,随即迅速将双手掌按抚于双眼上。待热感不明显时,再如法重试一次,每日如此循环14次。此法有通经活络,改善血液循环的作用。运目自然站于窗前2～3米外,双眼依次注视4窗角,顺时针方向,逆时针方向反复交替,共反复7～14次。此法可以舒筋活络、改善视力。     

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。     

腹腔镜下性腺切除术17例临床分析

性分化和发育异常，临床非常少见，其中一部分患者因含有Y染色体需要切除性腺。传统的手术方式是开腹探在，再行陛腺切除。我们自2003年7月至2005年10月，开展了腹腔镜下性腺切除术，效果满意。现报道如下。     

CMU化疗方案辅助手术治疗临床Ⅲ期乳腺癌

 1982年6月至1984年12月，随机分组采用CMU方案辅助手术治疗可手术的临床Ⅲ期乳腺癌71例（用药组35例，对照组36例）。所有病人均行根治术及术后给予放疗。其5年无瘤生存率两组分别为74.2%及44.4%（P=0.01），表明围手术化疗可以提高Ⅲ期乳腺癌的预后。
