Objective To investigate characteristics of emotional intelligence(EI)and the ways of occupational stress coping in nurses as well as the predictive validity of EI on coping strategies.Methods 464 nurses from general hospitals were collected and evaluated with psychometric instruments including:Wong's Emotional Intelligence Scale(WEIS)and Nurse Ways of Coping Questionnaire.Data were conducted by Logistic regress analysis according to key themes.Results (1)Nurses' demographic characteristics had effects to the ways of occupational stress coping and emotional intelligence.However,there was no statistical difference of El varied with education levels(P＞0.05).(2)Both problems solving and positive recognition are main coping styles of nurses towards occupational stress.Either avoidance or self-reproach was seldom coping strategies of nurses toward occupational pressures(2.60±0.55;2.60±0.75;1.37±0.69;respectively).(3)El was correlated with coping styles(r=-0.123～0.253,P＜0.05,P＜0.01).Conclusion Four dimensions of EI positively or negatively predicted six kinds of occupational stress coping strategies separately.

To prepare sustained phenylpropanolamine*HCl (PPA*HCl)-resin complexes and to study the factors influencing the in vitro dissolution of it. METHOD: The sustainedPPA*HCl-resin complexes were prepared by coating the complexes with different kinds of ethylcellulose (EC) as coating embranes. The factors influencing the release rate of PPA*HCl from the complexes, such as resin particle size, the viscosity and thickness of coating membrane, the dispersion medium of EC (water or alcohol) as well as thepH and ion strength of dissolution medium were studied in detail. RESULTS: Thefactors above all influenced the dissolution of the complexes to ifferent extent. When prepared by EC 200 Pa*s (150 g*kg-1), the dissolution of the coated complexes in 0.1 mol*L-1 HCl accorded with the requirements of sustained PPA*HCl capsulesof USP ⅩⅩⅢ. ONCLUSION: The sustained PPA*HCl can be prepared by coating the drug-resin complexes with EC.

Targeted therapy means transporting drugs to certain tissue,aiming at increasing the utilization of drugs as well as reducing cytotoxicity.Chemotherapy drugs carried by carbon nanotube have high pharmaceutical activity and tumor control rate,compared with drugs alone.Carbon nanotube combined with immunotherapy drugs and nucleic acid can treat tumors at immunology and gene level.

ObjectiveTo study the distribution,location and hemodynamics of perforating branches of the ulnar artery with color Doppler flow imaging (CDFI).MethodsPerforating branches of ulnar arteries were examined in 80 healthy volunteers in both forearms using CDFI.Following parameters were detected:number,diameter,jumping-off point,course,location and peak blood velocity.All the parameters data were analyzed statistically.ResultsThree hundred and forty-five perforating branches were detected in total 160ulnar arteries.These branches were classified into three types:type Ⅰ,myocutaneous perforator (10.3 ％);type Ⅱ,septocutaneous perforator(87 ％ ) ; type Ⅲ,direct cutaneous perforator (2.7 ％ ).The most dominant branches were located in the mesial of the upper third,middle third and lower third of the forearm.There was no significant difference among all age groups and no difference in peak blood velocity between left side and right side( P ＞0.05).The peak blood velocity was higher in male than that in female.( P ＜0.05).In relaxing period,the blood flow rate was almost disappeared and the frequency spectrum showed the characteristics of single direction,lower blood velocity and higher blood resistance.ConclusionsCDFI with high resolution showed better results of distribution and location of perforating branches of the ulnar artery and a better quality evaluation of the these branches.CDFI was helpful to design the skin flap containing cutaneous perforators of ulnar artery.

Objective To establish HPLC method for determination of (R,S)-epigoitrin in Banlangen granules and discuss the content limitation. Methods The samples were separated on SHIMADZU VP-ODS (150 mm×4. 6 mm, 5 μm) and the mobile phase consisted of methol-0. 02% phosphoric acid solution (7:93) at a flow rate of 1. 0 mL. min-1 . The detection wavelength was set at 245 nm and the injection volume (in automatic sampler) was 10 μL. The content limitation was assessed according to the transfer rate and statistical data of the results. Results (R,S)-epigoitrin showed a good linear relationship at concentration of 0. 058 7 – 150. 349 5 μg·mL-1(r = 0. 999 7, n = 7). The average recovery rate was 98. 72% , 98. 40% and 98. 60% , respectively; RSD was 1. 84% , 0. 50% and 1. 82% , respectively. The content limitation of (R,S)-epigoitrin was unreasonable according to the transfer rate and the statistical data of the results. Conclusion The method is easy and simple to operate, accurate and stable in results, and highly specific, thus it is applicable for the quality control of Banlangen granules. The content limitation should be determined on the basis of pharmacokinetic and pharmacodynamic data.

Objective To study the clinical and radiographic characteristics of complicated axis fractures combined with adjacent segment instability and explore reasonable surgical treatment strategy. Methods A retrospective study was performed on 21 patients with axis fractures treated from August 2003 to June 2009. There were 14 males and 7 females at mean age of 34 years. The treatment strategy was based on the fracture type and the stabilities of adjacent atlantoaxial joint and intervertebral C2/3.Treatment strategies included anterior C2/3 interbody discectomy and fusion, anterior cervical plate internal fixation, odontoid screw fixation, posterior C1-2 pedicle screw fixation, cervical lateral mass screw fixation or combined anteroposterior approach. Results All patients were immobilized in a hard collar for thee months and followed up for 6-36 months (average 12 months), which showed bony fusion and cervical stability, with no intraoperative surgery-related complications such as loosening, extrusion or breakage of fixation, vertebral artery injury, nerve damage, cerebrospinal fluid leakage or wound infection. Neurological recovery was observed in five patients. Conclusions For complicated atlas fractures, correct identification of fracture type and instability disturbance of adjacent atlantoaxial joint and C2/3 as well as active treatment can conduce to better effect.

Objective Through early systemic nursing intervention of cervical cancer patients for promotion of the recovery of urinary bladder function, to remove the urethral catheter in advance,and reduce the occurrence of urinary bladder dysfunction. Methods 80 cervical cancer patients after total hysterectomy were divided into the treatment group and the control group with 40 cases in each group stochastically. The treatment group was given systemic nursing( psychological nursing,pelvis bottom muscles exercising,urination discontinuance exercising,abdominal muscle exercising,Valsalva maneuver exercising, Crede press exercising,open the urethral catheter timely and individually,cheiropractic with hot roller), the control group received conventional nursing and some simple training of urinary bladder function. The time of indwelling urethral catheter after the hysterectomy was compared. Results The time of indwelling urethral catheter in the treatment group and in the control group were (9.65±49)days and (15.88±03)days respectively. The incidence rate of residual urine,urine retention and infection of urinary system after surgery in the treatment group was lower than that of the control group. Conclusions Early systemic nursing intervention can shorten the time of indwelling urethral catheter after hysterectomy, reduce the occurrence of urinary bladder dysfunction .improve the surgery effect for the cervical cancer patients and ameliorate their quality of life.
