Objective:To explore the status of job burnout among clinical nursing teachers in different depart-ments, in order to provide reference for the nursing education management .Methods:The questionnaire of Maslach Burnout Inventory ( MBI) of revised Chinese Version was distributed to 535 clinical nursing teachers .Results:The incidence of job burnout was 48 .3%, while the incidences with mild , moderate and severe job burnout accounted for 18 .9%, 15 .7%, 9 .3%respectively .Clinical nursing teachers in different departments have diffrences on oc-cupation actions .Clinical nursing teachers in the operation room revealed a significant greater personal accomplish -ment, but the emergency department scored lower .The teachers in emergency department scored higher on emotion-al exhaustion than those in other departments , and the teachers in oncology department is the secondary in scores of emotional exhaustion .The scores of the teachers in oncology department were the highest on depersonalization among all the departments,while the teachers in infection department is at the secondary place .Conclusion:The clinical nursing teachers'job burnout should be paid attention to .Strategies including intervention by nursing education management and teachers'learning and training should be taken to reduce the damage of physical and mental health caused by burnout and increase the clinical care and teaching quality .

OBJECTIVE: To observe the application of the tragus cartilage in tympanoplasty. METHOD: Thirty-eight patients with tympanoplasty carried out tragus cartilage-perichondrium repairing tympanic membrane. The air-bone gap changes and the recovery of patients'tympanic membrane were evaluated at pre-operative and two months after the operation. RESULT: Thirty-one patients finishing follow-up visit showed tympanic membrane healed and looked like normal appearance in 1 to 3 months after the operation. The postoperation narrow of the air-bone gap >18 dB, tragus looked normal. CONCLUSION Tympanic membrane reconstruction using the tragus cartilage-perichondrium is feasible for tympanoplasty, and the survival rate and postoperative hearing would be acceptable.

Objective To investigate the effect of preconditioning electrostimulation of fastigial nucleus (FNS) on the neuronal mitochondrion of rats early after cerebral ischemia. Methods Forty Wistar rats were used and divided into 5 groups: a normal control group, a sham FNS group and 3 FNS groups. The FNS of the rats in the FNS groups was conducted for 1 hr, 1 day or 7 days, respectively, before the models of middle cerebral artery occlusion(MCAO)were made with them. Three hours after the model was established, the animals were sacrificed and the water content of the brain of the ischemic side was measured. The neuronal mitochondrion was observed by electron microscope, and its Vv, specific volume (Sv) and specific surface (Ss) were analyzed. The rats in the normal control group were not given any special treatment. For the rats in the sham-FNS group, intrinsic neurons of FN were destroyed with ibotenic acid (IBO), and 5 days later, the FN was electrically stimulated, and 1 day later, MCAO models were made. Results Three hours after MCAO, the water content of the brain increased and neurological function score decreased in the sham-FNS group, while the Vv and Sv of neuronal mitochondrion increased and the Ss decreased, which were significantly different from those of the normal control group(P

Objective To investigate whether lamivudine antiviral treatment after radical surgery can prolong disease-free survival of patients with hepatitis B virus-related liver cancer.Methods A total of 120 patients with hepatitis B virus-related liver cancer who underwent conventional radical surgery in Dongfeng Hospital Affiliated to Hubei Medical College from March 2014 to March 2016 were enrolled,and among these patients,60 were given conventional treatment (group A) and 60 were given lamivudine antiviral treatment (group B).ELISA was used to measure serum HBV DNA level.The t-test was used for comparison of continuous data between groups,the chi-square test was used for comparison of categorical data between groups,the Kaplan-Meier method was used to compare disease-free survival rate and recurrence rate between groups,and the Spearman method was used to investigate the correlation between serum HBV DNA level and survival time.Results According to the results of the 3-year follow-up,71 patients (59.17％) died (group A:46 patients died of tumor and 4 died of hepatic encephalopathy;group B:20 died of tumor and 1 died of hepatic encephalopathy).Compared with group A,group B had significantly lower recurrence rate (48.33％ vs 90.00％,x2 =16.98,P ＜0.001) and mortality rate within 3 years (35.00％ vs 83.33％,x2 =10.34,P ＜ 0.001).Group B had significantly higher mean disease-free survival time and 1-,2-,and 3-year dis-ease-free survival rates than group A(t =9.82,x2 =7.87,11.43,and 7.98,all P ＜ 0.001).After surgery,group B had a significantly lower serum HBV DNA load than group A [(0.008 1 ±0.003 2) × 105 copies/ml vs (0.014 3 ±0.008 9) × 105 copies/ml,t =18.54,P ＜ 0.001].In group A,there were significant differences in 1-,2-,and 3-year disease-free survival rates between patients with serum HBV DNA load ≥ 1.0 × 105 copies/ml and those with serum HBV DNA load ＜ 1.0 × 105 copies/ml (x2 =8.57,P ＜ 0.05),and further analysis showed that there were significant differences in 1-,2-,and 3-year disease-free survival rates (x2 =4.36,5.36,and 9.53,P ＜ 0.05);in group B,there were no significant differences in 1-,2-,and 3-year disease-free survival rates between these two groups of patients (P ＞ 0.05).Serum HBV DNA expression was positively correlated with patients' survival time (r =0.67,P ＜ 0.001).Conclusion Lamivudine antiviral therapy after radical surgery can effectively reduce serum HBV DNA level,and helps to prolong the disease-free survival time of patients with hepatitis B virus-related liver cancer.

The mature seeds and excised embryos of Dalbergia odorifera were used as materials to study the effect of moisture content on their survival, as well as the effect of rapid freezing and vitrification freezing method on seeds and in vitro embryos cryopreservation. The results showed that the germination rate and vigor decreased from 82.67%, 85% to 18.35%, 25% respectively, when the seed moisture content decreased from 15.04% to 8.14%; and the germination rate decreased from 82.67% to 37.50%, 25.37% respectively by vitrification freezing method and rapid freezing method, when the seed moisture content decreased from 15.04% to 9.37%. Among all the moisture content gradient, 12.35% moisture reached the maximal germination rate, which were 63.58% and 50.45% respectively by vitrification freezing and rapid freezing; and when the embryo moisture content was 26.32%, the germination rate decreased from 95.67% to 58.31% and 33.82% respectively by vitrification freezing and rapid freezing. And when the moisture content was in the range of 14.17% -21.34%, the germination rate was a bit of decrease. The experiment results showed that the optimum conditions of seed cryopreservation were: moisture content 12.35%, vitrification freezing; and the optimum conditions of in vitro embryo cryopreservation were: moisture 15.04%, vitrification freezing. In conclusion, the effects of moisture content on germination rate after cryopreservation in D. odorifera seeds and embryo were significant, and vitrification freezing method is much better than rapid freezing method.
