Effects of social skills training on improving social skills of patients with schizophrenia

This study examined the effect of conversation and assertive skills training on social skills of schizophrenic patients. Patients who met the study criteria were randomly assigned to the experimental or control group. The experimental group received eight group training sessions and the control group received routine nursing care treatment. Data were collected at pretreatment (before group treatment), intratreatment (after fourth group treatment), posttreatment (after eighth group treatment), and follow-up (1 month after the end of group treatment). Conversation and assertive skills of the experimental group improved significantly with treatment and were superior to the control group at intratreatment, posttreatment, and follow-up. We suggest incorporating social skills training into treatment plans for patients with schizophrenia to improve their social skills ability.

Enhancing repair of the mammalian heart

The injured mammalian heart is particularly susceptible to tissue deterioration, scarring, and loss of contractile function in response to trauma or sustained disease. We tested the ability of a locally acting insulin-like growth factor-1 isoform (mIGF-1) to recover heart functionality, expressing the transgene in the mouse myocardium to exclude endocrine effects on other tissues. supplemental mIGF-1 expression did not perturb normal cardiac growth and physiology. Restoration of cardiac function in post-infarct mIGF-1 transgenic mice was facilitated by modulation of the inflammatory response and increased antiapoptotic signaling. mIGF-1 ventricular tissue exhibited increased proliferative activity several weeks after injury. The canonical signaling pathway involving Akt, mTOR, and p70S6 kinase was not induced in mIGF-1 hearts, which instead activated alternate PDK1 and SGK1 signaling intermediates. The robust response achieved with the mIGF-1 isoform provides a mechanistic basis for clinically feasible therapeutic strategies for improving the outcome of heart disease.     

126例急性白血病异常免疫表型分析

白血病细胞异常免疫表型是区别于正常造血细胞的重要特征之一,也是流式细胞术检测微小残留病的基础。为了了解急性白血病的异常免疫表型特征,本研究采用四色流式细胞术CD45/SSC双参数散点图设门技术对126例急性白血病患者的异常免疫表型进行分析,并初步探讨其在微小残留病检测中的意义。结果显示:约76%的患者可以检测到明确的异常抗原表达,白血病异常免疫表型可分为以下四类:抗原跨系列表达、跨阶段表达、过度表达及缺失表达,其阳性率分别为39%、46%、21%和29%。约11%的患者仅发生了单一的表型异常,其余患者则可以检测到两类或更多的表型异常。结论:在大多数急性白血病患者中可以检测到明确的白血病异常免疫表型,在此基础上应用多参数流式细胞仪可以有效检测微小残留病变。
