Medical Journal of Chinese People's Liberation Army 1982;0(03):-
Objective To develop a prediction scale for mental disorders in servicemen, and examine the reliability and validity of this scale. Methods The mental disorders prediction scale was developed by exploring the risk factors inducing the mental disorders. The initial scale included 11 subscales and 102 items. One thousand and four hundreds of soldiers were chosen by random cluster sampling, and tested with this scale, of whom 54 soldiers were tested with Chinese Military Mental Health Scale (CMMHS), 61 with Eysenck Personality Questionnaire (EPQ) at the same time, and 53 were retested after 1 week. The reliability and validity of the scale were examined by Exploratory Factor Analysis and Correlation Analysis. Results According to the results of factor analysis, 11 factors were extracted, named unhealthy defense mechanism, psychosis, depression, personality disturbance, mania, social support deficiency, introversion, family and past history, stressor, neurosis, and growth experience, respectively, and there were 96 items in the formal scale when one lie factor was added. The test-retest correlation coefficients of total scale and subscales were 0.397-0.867 (P

BACKGROUND: Xenograft cortical bone is an easy and inexpensive bone graft material, which has good biocompatibility and bio-mechanical properties. As a bone graft, it can function as biological framework for new bone growth and bio-supporting. Moreover, it can also be processed into internal fixation devices.OBJECTIVE: To review the biological properties, preparation methods and clinical applications of heterogeneous cortical bone for fracture fixation.METHODS: A computer-based online search of Pubmed database (1990-01/2009-05) and CNKI (1990-01/2009-05) was performed for related articles with key words of "Xenograft cortical bone, Bone graft, Fixation" in English and Chinese.RESULTS AND CONCLUSION: A total of 128 articles were collected. Xenograft cortical bone has a good biological performance, in particular, a certain degree of bio-mechanical properties. It is not only able to complete bone filling, bone induction, but also function as internal fixator following processing. However, the traditional preparation process reduces their bio-mechanical properties. Heterogeneous cortical bone can be widely used in intra-articular fractures and cancellous bone fracture fixation, and can be self-absorbed, avoiding the second operation. However, its instability limits its initial mechanical properties of fractures at other sites.

Purpose:To explore the tumor cell responses after IFN-? gene transfer by analyzing the expression of cell surface antigen,apoptosis and the impact of cell period. Methods:We constructed IFN-? gene expression vector-pcDNA3- IFN-?, and transfected it into HeLa cell lines by Lipofectamine. The expression of IFN-??the Human Leukocyte antigen(HLA-DR) after gene transfer were measured. The apoptosis of tumor cells and the variety of cell period were also measured to investigate the anti-tumor mechanism by IFN-? gene therapy. Results:The results showed that the HLA-DR expression in Hela cell lines increased significantly(P

Acute myocardial ischemia and reperfusion led to arrhythmias and increase of glutamic oxalacetic transaminase (GOT),lactate dehydrogenase (LDH),non-csterified fatty acid (FFA) and malondialdehyde (MDA) content, and decrease of superoxide dismutase (SOD) activity in rats. 3, 6-di-methylamino-dibenzopyri-odonium edetate (IHC-72) 5 mg?kg-1 iv significantly reduced the incidence of ventricular tachy-cardia (VT) and ventricular fibrillation(VF) ,shortened the duration of arrhythmias induced by reperfusion, decreased the release of GOT, LDH and FFA, obviously reduced the MDA content,and effectively protected SOD activity in ischemia-reperfused rat hearts. Our experimental results suggested that IHC-72 had protective effects on ischemia-reperfusion injury rat hearts in vivo. The mechanism of the protection might be associated with the inhibition of cellular lipid peroxidation.

Objective To analyze the causes of misdiagnosis of aorta diseases for simple inferior limb artery thrombo-embolism,and summarize the clinical experience. Methods Retrospective analysis was made on clinical data of 9 eases misdiagnosed aorta disease,including clinical manifestation,misdiagnosis,improper treatment and final definite diagnosis. Results All 9 cases were misdiagnosed as simple inferior limb thrombo-embolism at first.Three cases were treated with emergent thrombectomy using Fogarty catheter.The correct diagnosis Was achieved by 3-dimensional CT angiography (3DCTA) after operation,and the eitiology of other 6 cases were also pmved as aortic disease by 3DCTA before operation.Among 5 cases of acute aorta dissection with iliac-femoral artery involved,2 cases abandoned surgery with one dying the next day and the other lost to follow-up after being discharged.The other 3 cases were treated with endovascular therapy successfully.One case of abdominal aorta anurysm with mural thrombosis defluxion were treated by aneurysm resection.The other 3 caBes of Leriche syndrome with acute aorta terminal filament thrombosis formation were cured by aortoiliac bypass.The limbs ischemia were improved in all cases without perioperative death.Conclusion Aorta diseases can sometimes lead to acute inferior limb ischemia,mimicking limb artery thrombo-embolism.Preoperative imaging especially 3 DCTA helps to establish correct preoperative diagnosis for a successful treatment.

AIM To get an insight into intracellular signaling steps, a very early step in the signaling cascade, the biphasic Ca 2+ elicited by 5 HT in rat stomach fundus smooth muscle cells was investigated. METHODS Cells were cultured and loaded with Fluo 3 AM. [Ca 2+ ] i was measured by fluorescent intensity (FI) in each cell with confocal microscopy. RESULTS The resting FI level of SFSMC was 264?15. Stimulation of SFSMCs by 5 HT produced an elevation of [Ca 2+ ] i; Depletion of external Ca 2+ by addition of EGTA led to a significant attenuation of [Ca 2+ ] i change induced by 5 HT; Pre treatment of SFSMCs with ryanodine (10 ?mol?L -1 , 5 min) in D Hanks, the effect of 5 HT was completely inhibited; The stimulation of SFSMCs by 5 HT was partly attenuated by miaserin(10 ?mol?L -1 ), however, L type Ca 2+ channel antagonist lacidipine and G protein inhibitor NEM completely abolished the increase of [Ca 2+ ] i mediated by 5 HT; 5 HT mediated Ca 2+ release was reduced by phospholipase C specific inhibitor compound 48/80(1 2 ?g?ml -1 ); When protein kinase C was activated by phorbol 12 myristate 13 acetate (PMA 0 1 ?mol?L -1 , 5 min) the effect of 5 HT was inhibited, and the inhibitory effect of PMA was reversed by D sphingosine, a PKC inhibitor. CONCLUSION Our data suggest that G protein coupled 5 HT 2B receptor in the rat stomach fundus modulates 5 HT stimulated Ca 2+ increase, and it is coupled to calcium influx through L type calcium channels, and also intracellular calcium release by the opening of ryanodine receptor. The 5 HT 2B receptor mediated signal of 5 HT is transduced by PLC and PKC.
