Novel thermosensitive hydrogels based on polymerization of N-isopropyl acrylamide, Sodium acrylate, and diacetone acrylamide were synthesized. The swelling ratio and dynamic swelling were investigated. The results indicated that the hydrogels exhibited high water uptake and themosensitivity. The swelling properties and volume phase transition temperature could be adjusted by contents of the comonomers in the gels.

BACKGROUND ： The pathophysiology of tardive dyskinesia （TD） is not yet fully understood. With the hypothesis of altered dopaminergic neurotransmission, altered activities of dopamine degrading enzymes such as monoamine oxidase A （MAOA） and their coding genes are supposed to be related to the pathophysiology of TD. OBJECTIVE： To investigate possible association between 30 bp variable number tandem repeat （VNTR） polymorphism in the promoter of MAOA gene and susceptibility, severity of neuroleptic induced TD in Chinese Han people in Guandong Province. DESIGN ： Non-randomization-synchronization controlled study.SETTING： Guangdong Mental Health Institute, Guangdong Provincial People＇s Hospital; Guangzhou Psychiatric Hospital; Affiliated Psychiatric Hospital of Guangzhou Municipal Bureau of Civil Administration. PARTICIPANTS： A total of 179 subjects were enrolled in the study. All subjects were sporadic and genetically unrelated Chinese schizophrenic patients who were hospitalizing in Guangzhou Psychiatric Hospital or Affiliated Psychiatric Hospital of Guangzhou Municipal Bureau of Civil Administration during January to April 2005. The diagnosis of schizophrenia was made according to the criteria of Diagnostic and Statistic Manual of Mental Disorder-the third edition-revised （DSM-Ⅲ-R）. Among all patients, 88 were diagnosed as with TD and 91 without TD according to the research diagnostic criteria described by Schooler-Kane. Informed consent was obtained from all subjects or their relatives. METHODS ： ① TD seventy was assessed with the AIMS which was a 5-degree rating scale from 0 to 4 （corresponding to none, minimal, mild, moderate and severe, respectively）. The study was approved by the Ethics Committees of the two hospitals and informed consent was obtained from all subjects or their relatives. ② The polymerase chain reaction （PCR） and polyacrylamide gel electrophoresis （PAGE） techniques were used to detect MAOA gene 30 bp VNTR polymorphism in schizophrenic pa

在研究农村剩余劳动力情况时,文章以武汉市为代表研究对象,估测了武汉市农村剩余劳动力人数,发现该市农村剩余劳动力呈现递增趋势。通过采用主成分因子分析法和引力模型进行拟合,文章进一步发现如下因素促进了武汉市农村剩余劳动力的流转:城镇投资占社会总投资的比例、农村机械总动力、城乡收入差距;而阻碍流转的因素则包括:农村人均耕地面积、农村科教文卫投入占社会固定总投资的比例、城市失业率、农作物受灾面积占农村耕地面积的比例、农村年末总人口。

目的研究SSRIs治疗重性抑郁障碍(MDD)患者前后的血清脑源性神经营养因子变化及相关因素。方法收集符合DSM-Ⅳ重性抑郁障碍诊断标准的患者21例,均给予SSRIs系统抗抑郁治疗6周,治疗前后均采用HAMD24、HAMA评估抑郁焦虑症状,ELISA法检测血清BDNF水平。结果患者的HAMD24、HAMA及HAMD24各项因子分在治疗后均有明显改善,与治疗前相比差异有统计学意义(P0.05)。结论 MDD患者治疗后血清BDNF水平可明显提高,但与临床症状的改善无明显相关。
