Posttyphoon prevalence of posttraumatic stress disorder,major depressive disorder,panic disorder,and generalized anxiety disorder in a Vietnamese sample

In 2006, typhoon Xangsane disrupted a multiagency health needs study of 4,982 individuals in Vietnam. Following this disaster, 798 of the original participants were reinterviewed to determine prevalence and risk factors associated with posttraumatic stress disorder (PTSD), major depressive disorder (MDD), panic disorder (PD), and generalized anxiety disorder (GAD). Posttyphoon prevalences were PTSD 2.6%, MDD 5.9%, PD 9.3%, and GAD 2.2%. Of those meeting criteria for a disorder, 70% reported only one disorder, 15% had two, 14% had three, and 1% met criteria for all four disorders. Risk factors for posttyphoon psychopathology differed among disorders, but generally were related to high typhoon exposure, prior trauma exposure, and in contrast to Western populations, higher age, but not gender.     

保守性手术后促性腺激素释放激素激动剂联合反加疗法治疗中重度子宫内膜异位症的疗效观察

目的:探讨促性腺激素释放激素激动剂(GnRH-a)联合结合型雌激素(CEE)和安宫黄体酮(MPA)反加疗法用于中重度子宫内膜异位症保守性手术后巩固治疗的临床疗效及安全性。方法:将腹腔镜保守性手术后39例中重度子宫内膜异位症患者随机分为3组:反加组(13例)于术后皮下注射诺雷得3.6mg,每4周一次,连续6次,用药第4个月起加用倍美力0.625mg/d、安宫黄体酮5mg/d,连用3个月;单药组(14例)术后单用诺雷得治疗。对照组(12例)不用药物治疗。结果:反加组、单药组症状完全缓解率为92.3%、85.7%,显著高于对照组51%(P<0.01);治疗组累积复发率分别为7.1%、7.7%,显著低于对照组33.3%(P<0.01);单药组用药后血清黄体生成素(LH)、卵泡刺激素(FSH)、雌二醇(E2)明显低于治疗前(P<0.01)。结论:GnRH-a联合倍美力、安宫黄体酮反加疗法在缓解低雌激素症状、减缓骨转换等是安全有效的。反加疗法能减轻GnRH-a的副作用而不影响其疗效。     

Metrological characterization of the ADONIS system used in gamma-ray spectrometry.

In gamma-ray spectrometry, new acquisition systems based on digital signal processing are now commercially available. In order to determine their performance at high count rates, the Commissariat à l'Energie Atomique (CEA), Laboratoire National Henri Becquerel has tested several of these systems. These tests have clearly shown that the performance levels announced by the manufacturers were generally not met. It was therefore a logical step to include the Atelier de DévelOppement Numérique pour l'Instrumentation en Spectrométrie (ADONIS) system in these tests. ADONIS is the new numerical system for gamma-ray spectrometry, developed by the CEA Service d'Instrumentation et d'Application des Rayonnements.     

Developmental regulation of creatine kinase activity in cells of the epiphyseal growth cartilage.

During the process of endochondral bone formation, the maturing chondrocyte exhibits profound changes in energy metabolism. To explore the mechanism of energy conservation in cartilage we examined the expression of creatine kinase, an enzyme that catalyzes the formation of ATP in tissues under oxygen stress. Measurement of creatine kinase activity and cytochemical assessment of enzyme distribution clearly showed that the level of enzyme activity was related to chondrocyte maturation. Thus, as the cells hypertrophied, there was a progressive increase in creatine kinase activity. Similarly, an elevation in creatine kinase activity was noted in chondrocyte cultures as the cells assumed an hypertrophic state. When cartilage calcification was disturbed by rickets, there was a decrease in enzyme activity in the hypertrophic region. Studies were performed to examine the creatine kinase isozyme profile of cells of the epiphysis. In resting and proliferating cartilage, the isoform was MM. In hypertrophic cartilage, the predominant isoforms were MB and BB. In terms of the creatine phosphate content, the highest values were seen in the proliferative region; lower amounts were present in hypertrophic and resting cartilage; and no creatine phosphate was detected in calcified cartilage. These data suggest that turnover of creatine phosphate is greatest in the mineralized region of the epiphysis. The results of these investigations point to creatine kinase as being under developmental control. The activity of the enzyme in cartilage cells should serve as a marker of developmental events associated with chondrocyte proliferation, hypertrophy, and mineralization.
