Under the condition of microgravity, human body will experience a series of cardiovascular deconditioning. The vascular endothelial cells are the most important component of the vessel wall, so the changes of biological characteristics of vascular endothelial cells are directly related to cardiovascular deconditioning. Therefore, it is important to prevent and treat the cardiovascular deconditioning in astronauts by studying the effect of microgravity on biological characteristics of vascular endothelial cells.

BACKGROUND: There is a complicated relation between somatic disease and mental disorder. Somatic disease may induce functional disorder of brain, and generate psychiatric symptoms due to the change of psychological and social environment. The proportion of depression in elder people based on the chronic somatic disease is much higher, and thus the fatality of them increases.OBJECTIVE: To investigate the influence of single antidepressant, and therapeutic alliance of psychological and drug treatment on the rehabilitation of patients with elderly chronic somatic disease complicated with depression. DESIGN: Randomized and controlled grouping experiment.SETTING: Department of Senile Disease of Tongji Hospital Affiliated to Huazhong University of Science and Technology.PARTICIPANTS: Totally 102 patients were hospitalized in the Department of Senile Disease of Tongji Hospital Affiliated to Huazhong University of Science and Technology from March 2000 to January 2003, and all the patients had sleep disorder to a different extent, and suffered from symptoms of heart and alimentary tract which could not be explained as organic diseases, and chronic pain or systemic symptom. Their score of Zung scale was > 40 points with average of (48.83±4.15)points. The patients were randomly divided into the drug group (n=46) and the combined treatment group (n=56). Each patient had more than two somatic symptoms in the two groups and more than 81.0% of them had three somatic symptoms. METHODS: According to the different primary diseases in patients of the two groups, regular treatment was given routinely. Oral thymoleptics fluoxetine of 20 mg/d 5-hydroxyltryptamine reuptake restrainer with 20 mg/d was administered, the dose of which could be added to 40 mg/d according to the pathogenetic conditions. At the beginning of the administration of oral antidepressant drugs, the patients in the combined treatment group were The focal point of depression and fear was identified, and the comfort and edge related to the disease was supplied, and the pathogenetic condition and the prognosis were told to the patients objectively. The family and society were encouraged to learn the rehabilitative skill and improve their possible, and the family and society were encouraged to give the patients adequate psychological support and life support. The patient and the family were assisted to establish favorable communication. The feeling of loneliness and isolation was reduced, and the sense of safety was increased. The depression status and the quality of life of the patients in the two groups were evaluated before the treatment and at 2 and 8 weeks after treatment with the Zung scale and the Spitzer quality of life index score (QLI), including 5 aspects: Activity, daily life, health, support and perspective. The highest score was 10 points. The lowest was 0, and the higher the score, the better the quality of life is.MAIN OUTCOME MEASURES: The results of the Zung scale and the QLI score evaluated before the treatment and at 2 and 8 weeks after the treatment.RESULTS: The treatment of the patients in the two groups was all finZung scale in the drug group and the combined treatment group at 2 weeks after the treatment indicated that there was significant difference in comparison with those before the treatment (41.12±2.60,48.83±4.15,t =10.67,P < 0.05); (40.88±3.43,49.03±4.21 ,t=11.24,P < 0.05). There was not significant difference in group comparison. The total points of Zung scale at 8 weeks were significantly decreased (36.11 ±2.87 ), (30.71±3.62),and there was significant difference in comparison with that before the treatment. The combined treatment group was better than the drug group in difference of QLI score at 2 weeks between the drug group and combined treatment group before and after the treatment (5.47 ± 1.33,5.32 ± 1.04,5.55±1.18,5.27±1.35). The QLI score of drug group and combined treat ment group at 8 weeks after treatment began to rise 7.21±0.13 and 8.83 ±0.32 ,respectively, and there was significant difference in comparison withthose before the treatment, and there was also significant difference in group comparison.CONCLUSION: The positive and effective combined therapy of anti-depression significantly improved the somatic symptoms of patients, no complications appeared, and most patients presented optimistic attitude to the prognosis of the primary disease. To identify the depression of elder people in earlier period is very important to promote rehabilitation of the primary disease.

AIM: To investigate the effect of mfn2 on mitochondrial function in steatosis hepatocytes. METHODS: Plasmid pEGFP-mfn2 was transfected into hepatocyte strain L02 by Lipofectamine 2000 in vitro, then the steatosis model of hepatocytes was establish by oleic acid induction. RT-PCR was used to evaluate mRNA expression and Western blotting was use to detect the protein expression. ATP level was determined by firefly luciferase bioluminescent. ROS production was measured by fluorescence probe DCFH-DA. Chondrosome transmembrane potential of L02 was observed by labeling of JC-1 and FCM. RESULTS: The stable expression of ectogenesis mitofusin2 in L02 cells was confirmed by RT-PCR and Western blotting. In the model of oleic acids induced lipid formation, Mfn2 obviously inhibited the descent of chondrosome transmembrane potential and ATP level, and increased ROS production in L02 cells. CONCLUSION: Up-regulated expression of mfn2 attenuates mitochondria dysfunction caused by oleic acids induced lipid formation.

Objective To investigate the understanding level of asthma related knowledge and the treatment compliance in parents of children with asthma in Tianjin. Methods Questionnaire survey was given to 93 randomly selected parents of children with asthma at our asthmatic clinic ,whose children began to receive regularly asthmatic administration for at least 6 months from June to July in 2009. Results 72.04% of the parents included into the survey knew that asthma was a chronic airway inflammatory disease; 100% of them adhered to use prescription inhaled corticosteroid (55.91%) or inhaled corticosteroid combined with an inhaled long-acting β2-agonist (44. 09% ) ;74. 68% of them believed that if the child is in a well control state, he/she could participate in exercise as healthy children. There were 93.55% and 97.85% children patients aged > 5 had never used PEF meter or CACT respectively to monitor the ill conditions. 25.81% of the parents chose rapid-acting β2-agonist to deal with asthma at acute attack stage, while 19.35% chose to add antibiotics and 11.83% were unable to do anything. 43.01% of the parents worried that the long-term use of inhaled corticosteroid would have side effects on the growth and development of their children, although they chose to obey to the doctor's prescription. Conclusions The general understanding of asthma is good in the parents, whose children had received asthmatic administration regularly in Tianjin area,but there are still some weak links exist. The related education may help asthmatic children's parents to master the knowledge of asthma, give them correct recognition of the treatment and prevention of asthma,increase the treatment compliance. This work should be insisted continuously.

In the present research, two Chinese rhesus monkeys were inoculated intravenously with 5000 TCID50 of SIVmac239. The changes in the numbers of CD4+T lymphocyte in peripheral blood,plasma viral loads, proviral DNA and humoral antibodies against virus were periodically monitored during 121 days. At the early stage of infection, proviral DNA had been detected in PBMCs, and infectious SIVmac239 virus had been isolated from PBMCs. At the same period, the numbers of CD4+T lymphocytes were significantly decreased, and maintained at low level during the 121-day period of infection. Plasma viral loads reached the peak at week 2 post-inoculation and kept at a steady state subsequently. Moreover, antibodies against viral proteins were detected from plasma. All the results showed that the two Chinese rhesus monkeys had been infected with SIVmac239 successfully. This animal model can be applied for further AIDS researches.
