Objective To investigate the situation of knowledge,attitude and practice of physical restraint from nurses for critical parents in secondary hospitals and tertiary hospitals in Hubei province.Methods 300 nurses from four tertiary hospitals and four secondary hospitals were investigated for the situation of knowledge,attitude and practice of physical restraint by questionnaires.Results It showed that nurses had a good knowledge of physical restraint,(11.02±1.96),their attitude of physical restraint tended to be neutral,(34.99±3.52),the practice of physical restraint turned out to be at meddle-up level,(51.90±6.67).There was a statistically significant difference in the scores of physical restraint knowledge and practice between nurses who receive physical restraint train or not after they got a job,besides,there was also statistically significant difference in the scores of physical restraint knowledge between intensive department and non-intensive department,tertiary hospitals and secondary hospitals,however there was no statistically significant difference in the scores of physical restraint attitude and practice between them.Conclusions Compared with non-intensive department and secondary hospitals,the nurse managers of intensive department and tertiary hospitals should strengthen the training and education of physical restraint of clinical nurses,guide the nurses to build the positive attitude of physical restraint,to reduce the use of preventive physical restraint and then to promote their quality of practice on physical restraint.

Objective To research the significanec of genes bel-2 and bax in chondrocyte apoptosis in experimental osteoarthritis in rabbits.Method Twelve New Zealand rabbits divided into two groups at random:model group and control group.Model group with osteoarthritis was duplicated by immobilizing with gypsum at extension position in right hind limb of rabbits.Rabbits of model group were executed after 6 weeks and chondrocytes were taken.Positive expression rate of bcl-2 and bax mRNA was measured by immunohisto- chemistry and Terminal deoxynucleotidyl transferase mediated dUTP nick end labeling(TUNEL).Results Positive expression rate of mRNA in bel-2 and bax of model group was obviously more than control group(P＜0.05).According to immunohistochemistry,and grey grade of positive expression of protein in bcl-2 and bax of chondrocytes in model group was lower and positive expression rate was gigher compared with control group (P＜0.05,P＜0.01).bcl-2 and bax of model group were lower than control group(P＜0.05).Conclusion Genes bcl-2 and bax participate and thus accelerate chondrocyte apoptosis of osteoarthritis together.

According to the genomic sequence of foreign four PLRV isolates, three pairs of specific primer were designed and synthesized. The cDNA of the ORF2a gene of PLRV-Ch was synthesized by reverse transcription and followed by Polymerase Chain Reaction amplication. The synthesized 3' and 5' cDNA fragment of the PLRV-Ch ORF2a gene were inserted into pUC19 and cloned in E. coli JM109 and were sequenced respectively. The middle cDNA fragment were directly sequenced. The homology of nucleotide sequence of PLRV-Ch compared with PLRV-S (Scotland, UK), PLRV-N(Netherlands), PLRV-A(Australia) and PLRV-C(Canada) were 98.96%, 98.70%, 94.79%, 97.5%, the homology of putative amino acid sequence are 97.97%, 97.97%, 89.69%, 95.94%. In 3' region of ORF2a gene a slippery sequence for-1 frameshift and its downstream "stem-loop" or "pseudoknot" and upstream nucleotide sequence repeats were found. Authors suggested that the nucleotide repeat sequences characteristic for PLRV could form a tight successively folded complementary double stranded regions and hairpins. This structure possibly has something to do with-1 frameshift. The amino acid sequence of C terminus region of 70 kD protein translated by motif IV has a protease characteristic motif and a helicase motif IV. The amino acid sequence of polypeptide translated by ORF2a gene undergoing frameshift has a single-stranded nucleic acid binding protein-like characteristic motif.

Objective To investigate the protective effects of Digoxin on cardioventricular function in rats after simulated weightlessness.Methods Eighty rats were divided randomly into 5 groups:control(Con)group,tail-suspended+sham feeding(TS+SF)group,tail-suspended+Digoxin 2 wk(TS+D2)group and tail-suspended+Digoxin 3 wk(TS+D3)group.The TS+SF group was given the distilled water.At the end of tail-suspended for 3 weeks,the heart function of 10 rats in each group was examined with echocardiography.The level of atrial natriuretic polypeptide(ANP)in serum was measured with immunoradiometric assay in other 6 rats.Results Compared with TS+SF group,the contractile function of LV improved in TS+D2 and TS+D3 groups(P0.05).Conclusion Digoxin can improve muscle contractile and blood ejection of LV and retard the tendency of atrophy in simulated weightlessness.

0.05).The FMPV of the B?448 AA plus GA was higher than that of the GG type in obesity group(P0.05).Conclusions The simple obesity in children is associated with Fg and FMPV,which have become the high risk factors of the disease of heart and brain.The Fg B?448 G/A gene polymorphism may be an accumulative efficiency gene of children with simple obesity by influencing FMPV.

OBJECTIVE: To investigate the main point of long backbone fracture caused by blunt force in forensic clinical identification and to provide a reference for the inspection and appraisal practices of such injury. METHODS: Ninety-nine cases of adult long backbone fractures were collected from January 2006 to December 2013 in Gutian County of Fujian Province. According to the terms of fracture location, mode of injury, type, the data were summarized. RESULTS: In the 99 cases, there were 36 cases caused by hitting, kicking, and falling and 63 cases caused by vehicle collision. The majority of the former was ulna, and those of the latter were tibia and fibula. The types of fracture were transverse one, short oblique one, long oblique one, and spiral one. CONCLUSION Different types of long backbone fracture, not only causing stress load of fractures as well as structural differences related to each segment.
