RESUMO
Clinical trials of anti-tumor drugs is not only the important way to develop new drugs, but also the most advanced treatment methods for malignant tumors, bringing survival benefits to patients. There are a large number of new anti-tumor drug clinical trials for lung cancer patients, covering a wide variety of anti-tumor drugs, and with rapid progress and high efficiency of clinical transformation. These trials could not be carried out successfully without the joint efforts of the research team, in which the research nurses also played a role that should not be underestimated. Combined with the work content of clinical research nurses, this paper introduced the post management, role function, core competence and career development prospect of clinical research nurses in the process of carrying out clinical trial of lung cancer drugs in detail. In order to provide reference for more medical institutions to carry out related work, and promote the further development of clinical research nurses to standardization and specialization. .

On the basis of medical literature review and clinical research experience, the authors analyzed the reasons for low recognition rate of depression and poor progress of traditional Chinese medicine (TCM) differentiation of depression in this paper and put forward that depressive episode symptoms and the corresponding common terminology classification of Chinese and Western medicine should be the breakthrough points. Through symptom stratification and combination, as well as distinguishing between primary and secondary symptoms, the comprehensive integrative medicine clinical assessment of depression was explored so as to further obtain expert consensus and provide a methodology reference for the TCM differentiation of depression and the research of etiology and pathogenesis.
RESUMO
Objective To observe the effects of electro-acupuncture on behavior and the level of brain-derived neurotrophic factor(BDNF) in the hippocampus of rats with chronic stress depression. Methods Forty Sprague-Dawley male rats were randomly divided into four groups:a normal control group, a model control group, an electro-acupuncture group and a fluoxetine hydrochloride control group. All rats except the control groups were singly test and by the volume of sugar solution drunk in 24 hours. The levels of BDNF in the CA1 and CA3 pyramidal and dentate gyrus of the hippocampus were investigated immunohistochemically. Results Compared with the normal control group, the model rats'crossing squares, rearing, and grooming in the open field test and the volume of sugarsolution drunk were all less, while their time in the central square was clearly greater. Fluoxetine or electro-acupuncture could significantly improve behavior. Compared with the model group, BDNF immunoreactivity in the hippocampal neurons of the electro-acupuncture group was increased significantly and the average gray value of neurons decreased.Conclusions Electro-acupuncture can improve behavior and the level of BDNF in the hippocampal neurons of depressed rats. It has a significant antidepressant effect.
RESUMO
To investigate the effects of Chaihu Shugan San (CHSGS), a compound traditional Chinese herbal medicine, on behavior and plasma levels of corticotropin releasing hormone (CRH) and adrenocorticotropic hormone (ACTH) of rats with chronic mild unpredicted stress depression.
RESUMO
Objective To study mRNA expression of neuroglobin (NGB) in thalamus of DAI rats and explore the relation between NGB and heed injury. Method 46 male SD rats were randomly divided into four groups. The DAI model was established according to modi-fied Mamamu method. The mRNA expression of NGB in thalamus at different time point after injury was detected by RT-PCR method. All data were analyzed with statistical software. Result The mRNA expression of NGB in thalamus increased obviously from 30 minutes after in-jury while decreased at the 24th hour after injury. But the expression increased again and reached peak at the 48th hour after injury. Conclu-sion The mRNA expression of NGB in thalamus increased after DM. Those changes suggested NGB might participate in the response mech-anism of stress, secondary ischemia and hypoxic brain injury after neuron injury.
RESUMO
Objective To establish two-dimensional electrophoresis(2-DE) profiles with high resolution and reproducibility in analysis of hypothalamuses in the spontaneous hypertension rats(SHR) with hyperactivity of liver-yang to analyze the difference on the total proteins of hypothalamuses between the SHR and normal rats.Methods The total proteins of hypothalamuses in the rats were separated by immobilized pH gradient-based two-dimensional gel electrophoresis.With coomassie blue staining,the 2-DE image was analyzed by PDQuest 7.0 software.Results The average matching rate of the 2-DE images of hypothalamuses in the two kinds rats was 92% with good reproducibility.Proteins were mainly displayed at range of pI3-8,Mr(14.4～75) kD.The average spots in the SHR with hyperactivity of liver-yang and in the normal rats were 777?27 and 780?31 respectively.There were 22 spots of proteins up-regulated more than two times and 25 spots down-regulated more than two times in the SHR with hyperactivity of liver-yang than those of the normal rats.Conclusion There are 22 spots of proteins up-regulated and 25 spots of proteins down-regulated in the SHR with hyperactivity of liver-yang,which may be involved in the development of hyperactivity of liver-yang.
