Objective To explore the impact of transformational leadership on nurses'professional quality of life and organizational commitment by hierarchical linear modeling (HLM).Methods A total of 44,6 clinical nurses were investigated with demography questionnaire,professional quality of life questionnaire,organizational commitment questionnaire and transformational leadership questionnaire.Results The transformational leadership had positive predict ability to the nurses'compassion satisfaction,secondary traumatic stress and organizational commitment.The transformational leadership had negative predict ability to burnout.The transformational leadership could adjust the relationship between compassion satisfaction,secondary traumatic stress and organizational commitment.Conclusions The transformational leadership provides theoretical reference for nursing managers to effectively lead the team,increase professional life quality of the nurses,and then improve the level of organizational commitment of the nurses.

Objective: To study the effects of the total flavonoids of tartary buckwheat germ (TFTBG) on serum lipid and antioxidation in hypercholesterolemic rats. Method: According to body weight,60 Wistar rats were divided randomly into 6 groups: normal control group (NC), high-fat control group (HFC), Jiaogulan positive control group (JPC, Gynostemma pantaphyllum total glucoside tablet 0.032g/kg bw),TFTBG 1.0,0.5and TFTBG 0.2 g/kg bw (HD,MD,LD) group. Except NC group, all other groups were fed high-fat diet for hyperlipidemia model. NC group and HFC group were given distilled water 10 ml/kg bw. Water and TFTBG were given by gavage once a day for 6 w respectively. Serum TG, TC HDL-C, LDL-C, apoA1, apoB, SOD, GSH-Px and MDA were determined. Results: Compared with HFC group, serum TG ,TC were lowered significantly(P

Objective: To analyse the composition and content of the fatty acid and unsaponifiable matters in both tartary buckwheat seed oil and buckwheat seed oil. Methods: Fatty acids were obtained by the methods of KOH-EtOH(95%) saponification and treatment of inorganic acid. They were analyzed and determined by gas chromatography and GC/MS chromatography respectively. Results: 4-5 kinds of fatty acid were determined in both oils, and the content of unsaturated fatty acids in tatary buckwheat oil was 83.2% ( oleic acid 47.1%, linoleic acid 36.1%), buckwheat oil was 81.8% ( oleic acid 35.8% , linoleic acid 40.2% and linolenic acid 5.8%). The content of unsaponifiable matters in tartary buckwheat seed oil was 6.56%(?-sitosterol 54.37%), and in buckwheat seed oil was 21.90%(?-sitosterol 57.29%,?-tocopherol 1.41%). Conclusion: Both buckwheat oils were functional vegetable oils.

Objective To investigate the protective effects of midazolam on noise-induced hearing loss in guinea pigs by testing reactive oxygen species (ROS) level in the cochlea and plasma SOD and MDA. Methods Totally forty male pigmented guinea pigs were randomly divided into four groups: control (C) , midazolam (M), normal saline (S) and noise-induced deafened (D) groups, with ten guinea pigs in each. Groups M, S and D were exposed to a continuous noise (4kHz , octave band, 100dB SPL) 3h every day for 3 consecutive days. Group M was treated with midazolam, which was administered intramuscularly (0.1mg/kg) 24h before noise exposure, and immediately upon and during noise exposure. Group S was exposed to noise and treated with the same volume of normal saline intramuscularly, the time of injection was the same as that of Group M. Group C was not exposed to noise, but was treated with midazolam intramuscularly, the time of injection and the dosage were the same as those of Group M. Group S was exposed to noise and treated with normal saline intramuscularly ,the time of injection was same with that of Group M.Group D was exposed to noise only. All animals received auditory brainstem response (ABR) threshold recording before and immediately after noise exposure. Blood was collected when the guinea pigs were killed after the last ABR threshold recording, and serum SOD activity and MDA content were detected. Both the cochleae were removed and prepared for ROS assay. Results After noise exposure, ABR threshold shift (1.6±1.5) and ROS content [(291.10±2.30)u/mL] in Group M were significantly lower than those in Groups S and D [41.7±3.3, 44.3±3.9; (348.52±3.60)u/mL, (315.56±6.70)u/mL, P<0.05]. Serum SOD activity and MDA content were significantly increased in Group M, but the amplitude was less than that in Groups S and D.Conclusion Midazolam can prevent noise-induced hearing loss by reducing the increased ROS level in the cochlea after noise exposure.

Objective To investigate the association between chronotropic incompetence (CI)and motor ability in type 2 diabetic mellitus (T2DM) patients complicated with metabolic syndrome (MS).Methods One hundred and twenty patients with T2DM were enrolled in the study,including 66 cases with MS (MS group) and 54 without MS (non-MS group).The electrocardiographic exercise test was performed,the CI indexes including ratio of heart rate (rHR),heart rate reserve (HRR)were measured and the max metabolic equivalents(maxMETs) were calculated.Result The rHR(0.77 ±0.04 vs.0.81 ±0.06,t =3.41,P ＜ 0.05),HRR (0.62 ± 0.05 vs.0.70 ± 0.07,t =5.96,P ＜ 0.05) and maxMETs (8.8 ± 1.1 vs.9.7 ± 1.2,t =0.16,P ＜ 0.05) in patients of MS group all lower than those in non-MS group.The maxMETs were positively correlated with rHR (r =0.81,P ＜ 0.05) and HRR (r =0.78,P ＜ 0.05).Conclusion The results indicate that CI as well as maxMETs and rating of perceived exertion can be used as monitoring index in type 2 diabetic patients complicated with metabolic syndrome.

Objective To investigate the manifestation strategies of emotional labor and current status of emotional intelligence,further to discuss their correlation. Methods Investigation was carried out in 341 nurses by emotional labor scale(El.S) and emotional intelligence scale(EIS) and the results underwent analysis. Results In the aspect of emotional labor,nurses preferred natural manifestation instead of surface manifestation strategy.Nurses had strong ability of understanding and emotional control (P＜0.01) but weak perceptual emotional ability(P＜0.01).Emotional intelligence had higher predictive power for natural and inner presentation(P＜0.01),but was no related with surface manifestation(P＞0.05). Conclusions Different correlation existed between various manifestation strategies of emotional labor and emotional intelligence.Improvement of emotional intelligence can facilitate the application of natural manifestation and inner presentation.

Objective To explore the efficacy and safety of conversion from calcineurin inhibitor (CNI) to sirolimus (SRL) as major immunosuppressive therapy in lung transplant recipients.Method Retrospective analyses were conducted for the clinical data of all the patients undergoing lung transplantation in Wuxi People's Hospital between January 2011 and December 2014.Sixteen were given conversion treatment with Sirolimus in the postoperative irnmunosuppressive therapy.We analyzed the opportunity and reasons in the conversion treatment,and the safety,effectiveness and complications of the conversion treatment.Result The follow-up period was 8 to 25 months,and the median time of conversion was 6 months after operation (2-18 months).The indications of conversion concluded:malignant tumor (n =8),renal dysfunction (n =5),lymphangioleiomyomatosis (n =1) and intractable diarrhea caused by CNIs (n =2).Four cases suffered from interstitial pneumonitis associated with Sirolimus and one case suffered from spontaneous pneumothorax,and they all conversed back to CNIs.In those patients,cancer recurrence occurred in 4 cases (of them,there were 3 deaths),and 3 patients developed chronic rejection.Those recipients receiving the conversion treatment due to renal dysfunction showed recovery of renal function to some extent.Conclusion It's effective and safe to converse the immunosuppressive therapy based on Sirolimus.Sirolimus should be reduced or withdrawn when interstitial pneumonitis associated with Sirolimus occurred.

Aim: To explore the relationship between structure and immunological activity of marine polysaccha-ride YCP,the physicochemical property and immunological activity of the YCP-derived fragment were studied.Methods: YCP was hydrolyzed by α-amylase from human saliva.The hydrolysate was purified to obtain an polysaccharide fragment by gel filtration chromatography.The physicochemical properties of this YCP-derived fragment was characterized by HPLC,FT-IR and TLC.In addition,changes of phagocytic activity,production of reactive nitrogen and macrophage binding were investigated.Results: The relative molecular weight of YCP-de-rived fragment was approximately 6.6 × 10~3.The monosaccharide composition and FT-IR of the YCP-derived frag-ment were identical to YCP.No significant effect of the YCP-derived fragment on NO production and murine mac-rophage phagocyte were observed.And this fragment was not able to compete the binding between YCP and mac-rophages.Conclusion: The remarkable decrease of immunological activity of YCP-derived fragments degraded byα-amylase of human saliva suggests that the complete structure and high molecule weight of YCP are essential for its immuno-modulatory activity.

Objective To analyze the difference and correlation of the evaluation of the medical students' communication ability between the examiners,standardized patients (SP) and medical students themselves in objective structured clinical examination (OSCE),and to provide scientific basis for the appropriate evaluation method of medical students' communication ability.Methods OSCE was used to evaluate the communication ability of 90 medical students in Daping Hospital,Chongqing,and the three parties were evaluated by the examiners,SP and medical students themselves.Excel and SPSS 17.0 statistical analysis software were used,through Friendman M.test,t test and correlation analysis to analyze the differences and correlation of the three parties evaluations.Results The different evaluation between the three parties on the communication ability of medical students was as follows.Examiner's evaluation was the lowest (8.39 ± 1.18),SP's evaluation was the highest (9.62 ± 0.73),Medical students themselves' evaluation was higher (9.28± 1.09);The examiner's evaluation of Medical students' empathy,verbal communication ability,nonverbal communication ability and etiquette was lower (P=0.00).The correlation analysis of the three parties' evaluation showed that there was a significant correlation between the three parties on the connnunication ability,empathy and nonverbal communication ability (P＜0.05).The evaluation of SP and medical students themselves on medical students' language communication ability and etiquette was significantly correlated (P＜0.05).Conclusions Using examiner or SP or medical students themselves only to evaluate the communication ability of medical students is not accurate,The Examiner and SP as the main trial test personnel should collaborate to evaluate medical students' communication ability.The examiner can evaluate three projects such as what is medical ethics and law,empathy,nonverbal communication ability,while the SP can evaluate the two projects:what is language communication ability and etiquette.The collaborative evaluation of the two sides can be more accurate to reflect the doctor-patient communication ability of medical students.
