36例胰腺浆液性囊腺瘤的临床分析

目的：探讨胰腺浆液性囊腺瘤的诊断和治疗。方法：对1998年6月至2006年9月瑞金医院收治的36例病理诊断为胰腺浆液性囊腺瘤的临床资料进行回顾性分析。结果：胰腺浆液性囊腺瘤好发于中老年女性,多见于胰腺头颈部,无特征性临床表现。B超和CT诊断囊性肿瘤的正确率分别为69%（25/36）和94%（34/36）。CT对于囊腺瘤的诊断正确率为80%（29/36）,对浆液性囊腺瘤的诊断正确率为61%（22/36）。在不能排除或考虑实性假乳头状瘤的病人中MRI对于囊腺瘤的诊断正确率80%（4/5）。本组35例行手术治疗,其中7例行胰十二指肠切除;11例行胰腺节段切除;12例行胰体尾切除;5例行局部切除,1例行剖腹探查活组织检查。10例术后出现并发症,包括胰瘘、内出血、幽门梗阻、胰腺假性囊肿合并肠瘘病人及不同程度的胸腔积液。1例因内出血死亡。本组3例失访,32例获随访,除2例因其它疾病死亡,其余均健在,术后无复发。结论：CT和MRI,结合肿瘤学指标和临床病理特征可大大提高浆液性囊腺瘤的术前诊断率。浆液性囊腺瘤是一种良性的肿瘤,但手术治疗并发症较多。大多数浆液性囊腺瘤可考虑随访;有症状的胰腺浆液性囊腺瘤,或与黏液性囊性肿瘤不能鉴别者,应手术治疗。

精神病住院病例45年抽样分析

目的　对 4 5年来本院住院精神病病例的病种、分型、治疗措施和疗效等作一简要的回顾总结。方法　将自 195 4年 5月到 1999年 9月入院的病人 ,按首次入院日期每隔五年连续抽取 10 0份病例 ,扼要摘录有关内容进行登记、统计、分析。结果　男女病例数大致相仿。平均年龄 (31 9± 12 1)岁 ,平均住院日期 (6 2 1± 36 3)月 ,遗传史阳性率占 2 3 4 % ,精神分裂症占 5 4 % ,心境障碍占 13% ,癔症占 12 5 % ,电休克应用例数自 195 4年的 4 1 5 %降到 1999年的 2 % ,胰岛素治疗自 195 4年的 4 8%逐渐降低到 1989年 4 % ,1999年后为零。药物治疗西药自 5 7年的一种 (氯丙嗪 )增加到 1999年的 2 0余种。中药治疗经过 195 9年和 1970年的两个高潮 ,新针治疗自 196 9年至 1989年亦告结束。两者均无明显疗效。精神分裂症和心境障碍的显效率平均为 70 6 %和 90 8%。但均有评价过高之嫌。结论　根据我院的实践 ,传统的中药方剂、单味草药和“新针”治疗对主要精神病无明显疗效 ,195 9年后住院病人的疗效有明显的提高 ,愈来愈多的抗精神病药和取代了原有的胰岛素休克和电休克治疗。     

A prospective study of Toxoplasma-positive pregnant women in southern Brazil: a health alert

We evaluated anti-Toxoplasma gondii IgM-reactive pregnant women seen at a high-risk pregnancy outpatient clinic. From March 2005 to January 2008 in Paraná, Brazil, pregnant women seen by the Brazilian Public Health System, in any gestational period, who were anti-T. gondii IgM-positive, were followed. Clinical symptoms were noted, and tests performed including IgA, IgG avidity, ultrasonogram, and amniocentesis (PCR/inoculation in mice). Of 75 patients, 8 showed low, 3 intermediate and 31 high IgG avidity. Of those who underwent the avidity test, 31 (70.5%) were in the second trimester of pregnancy. Thirty-two (42.7%) pregnant women received specific treatment. Six received triple combination treatment; in three, tachyzoites were isolated, although only one was PCR-positive, showing changes in the cerebral sonogram, borderline IgA, and the Sabin tetrad. One fetus died, and one non-reactive IgM pregnant woman showed ocular recurrence. The municipality of residence, contact with cats during adulthood, and ingestion of unpasteurized milk were shown to be important risk factors. Congenital toxoplasmosis was observed in a pregnancy referred late for treatment. Follow-up of children born to mothers with diagnosed or suspected acute toxoplasmosis is crucial in the management of the changes that toxoplasmosis may cause.

Flavocoxid is as effective as naproxen for managing the signs and symptoms of osteoarthritis of the knee in humans: a short-term randomized,double-blind pilot study

Flavocoxid (Limbrel), a proprietary mixture of flavonoid molecules (baicalin and catechin), was tested against a traditional nonsteroidal anti-inflammatory drug, naproxen, for the management of the signs and symptoms of moderate osteoarthritis (OA) in humans. Discomfort and global disease activity were used as the primary end points, and safety assessments were also taken for both treatments as a secondary endpoint. In this double-blind study, 103 subjects were randomly assigned to receive either flavocoxid [500 mg twice daily (BID)] or naproxen (500 mg BID) in a 1-month onset of action trial. Outcome measures included the short Western Ontario and McMaster University Osteoarthritis Index, subject Visual Analogue Scale for discomfort and global response, and investigator Visual Analogue Scale for global response and fecal occult blood. Both flavocoxid and naproxen showed significant reduction in the signs and symptoms of knee OA (P ≤ .001). There were no statistically detectable differences between the flavocoxid and naproxen groups with respect to any of the outcome variables. Similarly, there were no statistically detectable differences between the groups with respect to any adverse event, although there was a trend toward a higher incidence of edema and nonspecific musculoskeletal discomfort in the naproxen group. In this short-term pilot study, flavocoxid was as effective as naproxen in controlling the signs and symptoms of OA of the knee and would present a safe and effective option for those individuals on traditional nonsteroidal anti-inflammatory drugs or cyclooxygenase-2 inhibitors. A low incidence of adverse events was reported for both groups.     

Zolpidem induced nocturnal sleep‐related eating disorder (NSRED) in a male patient

Nocturnal Sleep‐Related Eating Disorder (NSRED) is a well‐documented sleeping disorder where the person is reported to experience bizarre eating behavior during sleep. Although various causes are implicated in this disorder, role of drugs cannot be ruled out. Here we narrate an interesting rare case report of a drug‐induced new onset NSRED, where a 45‐year‐old man on zolipdem performed an unexpected and bizarre eating behavior during somnambulistic state, type of which has not been reported earlier in the literature. The case falls under even rarer category as such behavior in sleep is reported mainly in woman. © 2008 by Wiley Periodicals, Inc. Int J Eat Disord 2009     

17β-雌二醇对子宫内膜异位症患者在位子宫内膜间质细胞β-catenin mRNA和蛋白表达的影响

目的研究17β-雌二醇(17β-E2)对子宫内膜异位症(内异症)患者在位子宫内膜间质细胞β-catenin mRNA和蛋白表达的影响,探讨Wnt/β-catenin信号通路在介导雌激素促进内异症发生发展的作用。方法体外分离培养内异症患者在位子宫内膜间质细胞。用不同浓度17β-E2处理子宫内膜间质细胞48 h;此后选用10-10mol/L 17β-E2处理子宫内膜间质细胞12、24和48 h,逆转录聚合酶链反应(RT-PCR)和免疫印迹法(Western blotting)检测17β-E2处理前后子宫内膜间质细胞β-catenin mRNA和蛋白的表达水平。同法分析雌激素受体拮抗剂ICI182,780(10-6mol/L)对17β-E2促进β-catenin mRNA和蛋白表达的影响。免疫组织化学染色观察17β-E2作用后β-catenin在子宫内膜间质细胞中的定位。结果17β-E2能明显促进内异症患者在位子宫内膜间质细胞β-catenin mRNA和蛋白的表达,并呈剂量和时间依赖性,于10-10mol/L作用48 h最明显。雌激素受体拮抗剂ICI182,780能明显抑制17β-E2对子宫内膜间质细胞β-catenin mRNA和蛋白的表达。免疫组织化学染色发现17β-E2能促进β-catenin在子宫内膜间质细胞核内的表达。结论雌激素可能通过激活Wnt/β-catenin信号通路促进内异症在位子宫内膜的异位种植。
