OBJECTIVE:To investigate the protective effects of adjunctive general anesthesia of dexmedetomidine on cardiac and cerebral ischemia-perfusion injury. METHODS:50 patients,ASA physical status Ⅰ-Ⅱ,undergoing selective tracheal intuba-tion,were randomly divided into dexmedetomidine group (group D) and control group (group C) with 25 cases in each group. The patients in group D received a loading dose of 1 μg/kg of dexmedetomidine by infusion pump before anaesthesia,10 min lat-er by a maintenance dose of 0.5 μg/(kg·h)till the end of surgery;whereas patients in group C received normal saline and same induction. HR,SBP and DBP of 2 groups were monitored at the beginning of operation,10 min after incision,30 min after inci-sion,at the end of operation. Blood samples of vena jugularis interna were taken to determine the plasma levels of cardiac tropo-ninⅠ(cTnⅠ) ,adrenaline and norepinephrine before anesthesia induction (T0),at the end of surgery (T1),6 h after surgery (T2),12 h after surgery(T3),24 h after surgery(T4),48 h after surgery(T5). RESULTS:There was no statistical significance in the levels of HR,SBP and DBP in group D between during operation and at the beginning of operation(P>0.05);those in-dex were significantly lower than those of group C at corresponding time points,with statistical significance(P<0.05). The lev-els of cTnⅠ in group D at T2-T5 were significantly lower than in group C,with statistical significance(P<0.05). The levels of adrenaline and norepinephrine at T1-T5 were significantly lower than group C,with statistical significance (P<0.05). CONCLU-SIONS:Adjunctive general anesthesia of dexmedetomidline can improve cardiac and cerebral ischemia-perfusion injury to certain extent.

Objective To understand the occupational prevention status of clinical nurses in Guangdong province.Methods We investigated 500 nurses in 15 class-three-grade-one hospitals in Guangdong province on occupational prevention status by questionnaires.Results The incidence of pricking wound and incised wound by ampule was frequent.The percent of everyday incidence reached 44.2% and 49.0%.There were 68.2% of nurses wore gloves when contacting the body fluid and blood of patients,55.3% of nurses wore gloves when contacting chemotherapeutic drugs,53.1% of nurses wore gloves during hemospasia,57.2% of them wore gloves when handling urine.There were 52.1% of nurses did not use gauze for protection when handling ampule.There were 61.3% nurses knew related protection law,18.2% of nurses knew the coping process after the incidence of occupational injury.58.2% of nurses established related preventive measure and instructions,43.1% of nurses thought it was necessry for hospitals to produce more comprehensive and systemic occupational prevention instructions.Conclusions The cognition of occupational prevention of nurses was weak and they lacked occupational prevention knowledge.It is necessary to strengthen the occupational prevention education and training.

Objective To establish a purified model of rat retinal ganglion cells (RGCs) cultured by serum-free medium,and provide a good cell model to investigate the damage of RGCs in glaucoma,retinal ischemia,and degenerative retinopathy. Methods Two monoclonal antibodies,anti-rat SIRP (OX-41) against rat macrophage and antibody against rat Thy-1 (OX-7),were used to purify and characterize RGCs from 1-3-day old Sprague-Dawley (SD) rats by means of two-step filtration.Purified RGCs were cultured in serum-free neurobasal medium containing B27 and ciliary neurotrophic factor (CNTF) meeting the neuronal cell's special requirements.Photomicrographs illustration,immunfluorescence staining of Thy-1,calcein-acetoxymethyl ester (calcein-AM) fluorescence images were used to observe and identify cultured retinal cells and purified RGCs. Results Among the primary cultured rat retinal cells,91% were retinal neurons.Protuberances of RGCs were seen after cultured for 24 hours.At the4th to 8th day,many cells had uniform configuration,large body,and long protuberances. At the 14th day,over 60% cells maintained viability.Immunoflurescence staining of Thy-1 showed the purity of RGCs was about 90%. The results of calcein-AM staining,which stained the living cells only,showed large cell body of RGCs and most of RGCs had a protuberance whose length was twice longer than the diameter of the cells. Conclusion RGCs cultured by serum-free medium has uniform size,good configuration,and high purity,which is adapt to the research of damage of RGCs caused by various factors and to evaluate the protective effects of neuroprotective agents.

Objective To compare the differences in the use of effects of improved and traditional abdominal positioning locator card in the empty nest elderly diabetic patients with insulin pen injection. Methods 100 discharged cases of empty nest elderly diabetic patients with insulin treated were enrolled. They were divided into two groups by random digital table method, 50 cases in traditional positioning card injection group and 50 cases in improved positioning card injection group. Usage rate of two sets of locator cart, adverse reactions in local skin injection and blood glucose control were observed for 12 months. Results After 12 months, 44 cases occupied 88%in improved positioning card injection group were not about using positioning card while 30 cases occupied 60%in traditional positioning card injection group. The difference was statistical significance (P<0.05). After 12 months, only 3 cases in improved positioning card injection group appeared local injection site reactions which was significantly lower than 31 cases in the traditional positioning card injection group, and the difference was statistically significant (P<0.05);12 months later, fasting blood glucose (FBG), 2 hour postprandial blood glucose (2 h PBG), glycosylated hemoglobin (HbA 1c) of improved positioning card injection group and traditional positioning card injection group [(7.0 ±1.5) mmol/L and(7.8±1.9)mmol/L,(10.7±2.1)mmol/L and(12.3±2.2)mmol/L,(7.1±1.3)% and(7.7±1.5)%] were all decreased significantly than before. The difference was statistically significant (P<0.05). FBG,2 h PBG, HbA1c of improved positioning card injection group were decreased more significantly than that in traditional positioning card injection group and the difference was statistically significant (P<0.05). The standard rate of HbA1c [64% (32/50)] in improved positioning card injection group was higher than that in traditional positioning card injection group [42%(21/50)]. The difference was statistically significant (P<0.05). Conclusions The modified abdominal injection locator card can improve patients′positioning card usage rate, optimize insulin injection technique, reduce the occurrence of adverse reactions in local skin injection and improve the control of blood glucose.

Objective To sequence and analyze the full-length genome of one HEV strain,W2-1 isolated from a sporadic hepatitis E patient hospitalized in 1999 in Xinjiang,China.Methods Nested RT-PCR assays with 4 sets primers were used to amplify the entire genome.The PCR products were purified and sequenced.The full-length genome was acquired by assembling the fragmental sequences using the DNAstar 5.01 software.The genome of W2-1 was analyzed by comparing with the reference HEVs from GenBank.Results The complete genome of W2-1 is 7212 nt in length,including three open reading frames (ORF1-3) with 5079,1980 and 345 nt respectively,27 nt 5'UTR and 83 nt 3'UTR,and a 3' poly A tail.Phylogenetic analysis based on full-length genome showed that W2-1 belonged to genotype 1,subtype 1b.W2-1 had high homology with the HEV strains isolated in the large hepatitis E epidemic in Xinjiang in 1987-1989,sharing 97.2％-98.5％ nucleotide identity in the full length genome.W2-1 also showed high homology with 1b strains isolated in China after 2000,with 97.6％-99.2％ nucleotide identity.The specific amino acid sites in ORF1-3 proteins that distinct between genotype 1 HEV and the potential zoonotic strains did not change in W2-1.Conclusion W2-1 belongs to subtype 1b.The study indicates subtype 1b HEV has been circulating in China in a long period after hepatitis E outbreak in Xinjiang in 1986-1989.The amino acids of ORF1-3 of subtype 1b are conserved.
