Objective To know about the status quo and influencing factors of undergraduate nurses' psychological empowerment at present,and provide a theoretical basis for nursing administrators so as to take measures to raise the level of psychological empowerment of undergraduate nurses.Methods General information questionnaire for nurses,Psychological Empowerment Scale were used to survey 207 undergraduate nurses in 3 first class teaching hospital of Dalian City.Results Undergraduate nurses' psychological empowerment score was (43.890±6.515) points,four dimensions whose scores from high to low were self-efficacy,job significance,autonomy and job impact.There was statistical difference in terms of ages,working length,working positions,professional titles,working purposes and training opportunities.Among them,working position and working purpose were the most important influencing factors of psychological empowerment.Conclusions Psychological empowerment of undergraduate nurses needs to be improved,managers should pay attention to the role of psychological empowerment,and actively cultivate and correctly guide undergraduate nurses in order to stimulate their potential in work,and finally,promote the sustainable development of a solid nursing career.

Objective:To explore the effectiveness and recurrence prevention of esomeprazole at different doses in the patients with reflux esophagitis ( RE) . Methods:Totally 240 patients with RE were divided into mild or severe group with 120 cases in each accord-ing to the illness severity. The two groups were respectively divided into four groups according to the random number table, namely the full dose treatment group, half dose treatment group, intermittent treatment group and on-demand treatment group. The groups were fol-lowed up for 6 months, and GERD-HRQI scores, the recurrence rate and incidence of adverse reactions in all the groups were com-pared. Results:After the 6-month follow-up, the differences in the GERD-HRQI scores, recurrence rate and incidence of adverse re-actions among the groups with different doses were statistically significant (P<0. 05). The GERD-HRQI scores and RE recurrence rate in on-demand treatment group were significantly higher than those in the other groups(P<0. 05), and the incidence of adverse re-actions in the total dose treatment group was significantly higher than that in the other groups (P<0. 05). Conclusion: Intermittent treatment with esomeprazole at small dose can effectively prevent RE recurrence, reduce the incidence of adverse reactions and treat-ment costs, which is worthy of promotion.

Objective By measuring the concentrations of serum IL-2,IL-4,IL-8 and TNF-αin chronic bronchitis patients before and after the acupoint sticking therapy which was also called winter disease treated in summer to investigate the effect of therapy on serum concentrations of IL-2,IL-4,IL-8 and TNF-α.Methods 30 cases of patients diagnosed with chronic bronchitis in paracmasia and did not recieve other related treatment were randomly divided into acupoint application therapy group (treatment group)and the control group.The treatment group was giventhree Fuacupoint sticking therapy,the control group was given thecomfortacupoint sticking therapy.Serum IL-2,IL-4,IL-8 and TNF-αconcentrations were compared between the 2 groups before and after treatment.Results In the treatment group,the serum IL-2 concentration of patients after treatment was significantly higher than that before treatment(P <0.05),IL-8 and TNF-αconcentrations were significantly lower than those before therapy(P <0.05).Af-ter treatment,serum IL-2,IL-4 levels were significantly higher than those in the control group(P <0.05 )while IL-8 and TNF-αwere significantly lower than those of the control group(P <0.05 ).Conclusion Acupoint sticking therapy in summer for winter diseases effectively increase the concentration of serum IL-2 in patients with chronic bronchitis,reduced IL-8,TNF-α concentra-tions,and enhance their own immunity ability,reduce the degree of inflammation.

Objective: To study the relation of condylar morphology with different vertical facial types in the development of patients with skeletal Ⅲ malocclusions. Methods:180 cases with skeletal Ⅲ malocclusion were divided into children(5-11 years old), adolescence(12-17 years old) and adult(18-30 years old) groups with 60 cases in each group. Orthopantomograms of the patients with different vertical facial types were retrospectively investigated by computerized cephalometric analysis. Condylar morphology were compared among different age groups of the same vertical facial type. Results:In patients with high angle, ramus height(RH) was getting bigger with ageing(P0.05). In patients with low angle h and RH in adult group were bigger than those in adolescence or in children(P

Fluorocarbon emulsion, a substitute of blood, 20 ml/kg were injected once into dogs intravenously. As a result, part of the substitute deposited in the lympho-retic-ular system and was phagocytized by fixed and free histiocytes (rnonophagocytic system), and the histiocytes then converted into foaming cells.One month after injection, the fluorocarbon's deposits in the foaming cells remained at the peak level in the liver, spleen and other organs of the lympho-reti-cuJar system. After six months,no deposits could be found in all viscera and no signs of any pathological changes, except the spleen under a light microscope.After twelve months, no foaming cells were found in the spleen, liver, and kidney under light cmicroscope,yet but foaming cells could be found in the spleen and liver with the help of an electron microscope and we believed that this sign had no pathological significance in clinic practice.The target cells only showed the action of phagocitizing and depositing.According to our observation, the fluorocarbon emulsion is a non cytoplasmic toxin and an inert biologic substance, so there are no secondary histo-pathologic changes caused by fluorocarbon deposition. It seems that 20 ml/kg of fluorocarbon emulsion (equal to 1200 ml for adult human)injected intravenously is rather safe.

Objective To explore the time-related expressions of TGF-?1mRNA during the healing process of rat skin wounds. Method Using the method of the reverse transcriptase polymerase chain reac-tion (RT-PCR) on intra-vital rat skin incised wounds (0.5h, 1h, 3h, 6h, 48h, 72h, 96h, 168h after incision) and postmortem rat skin incised wounds (0.5h, 1h, 3h after incision) to detect the dynamics of expression Ievel of TGF-?1mRNA. The strength of the expression of TGF-?1mRNA in scanned image was using ID-Advanced software. Results The results of RT-PCR showed that TGF-?1mRNA Ievel increased at 0.5h after incision and elevated significantly after 3h. The peak of TGF-?1mRNA occurred at 48h. There was no obvious expression of TGF-?1mRNA in postmortem incised wounds. Conclusion The characteristics of the TGF-?1mRNA expression were potentially indicative for the wound aging. RT-PCR was a sensitive method for detection of the expression of cytokines in genic level.

Kaposi's sarcoma-associated herpesvirus (KSHV) is the primary etiological agent of Kaposi's sarcoma, primary effusion lymphoma and muticentric Castleman's disease. In common with the other herpesviruses, KSHV exhibits both latent and lytic life cycles, both of which are characterized by distinct gene expression profiles and programs. KSHV encodes proteins which play essential roles in the inhibition of host adaptive and innate immunity, the inhibition of apoptosis, and the regulation of the cell cycle. KSHV also encodes several proteins which have transforming and intrcellular signalling activity.
