An analysis of the existing incentives mechanism of performance appraisal for community health service centers, and insight into the challenges for linking the post performance appraisal in community health service centers with incentive measures. It is pointed out the administrators should take a variety of measures including material incentive, target incentive, knowledge incentive, and emotional incentive among others. In addition, such measures should be used sophistically, flexibly and reasonably, while timing of incentives should meet the human resource needs of the institution, notably a combination of positive incentive with negative ones,, mostly the former incentive.

A brief description of performance appraisal as used in the healthcare sector, and an analysis of problems existing in performance appraisal for posts in community heahhcare organizations in the country. The paper proposes a job-analysis based performance appraisal for such posts, featuring the appraisal model of "performance + skills + attitude+ work intensity". On the basis of work analysis, a job description should be worked out for such healthcare workers as doctors, nurses and prevention workers in community healthcare organizations, aided by a targeted job-based performance appraisal system. These efforts can effectively enhance the job performance in such organizations, catering to the healthcare needs of community residents.

Objective To study the mediating effect of big five personality between childhood abuse and anxiety of college students, and to provide basis to intervene their mental disorder.Methods Through stratified sampling,2374 college students in Jiangsu were investigated by the personal report of childhood abuse( PRCA),self-rating anxiety scale(SAS) and the revised NEO five-factor Inventory(NEO-FFI-R).A path analysis was applied by analysis of moment structures(AMOS) version 7.0.Results The path analysis showed that childhood abuse was directly related to anxiety of college students(Sβ=0.123, P＜0.01 ＝ ,and was directly related to 4 dimensions of the NEO-FFI-R( exclusion Openness dimension) (Sβ= -0.216 ～ -0.248,0.309; P ＜ 0.01 ＝.3 dimensions of the NEO-FFI-R( exclusion Openness and Extraversion dimensions) were directly related to anxiety of college students ( Sβ = 0.525,-0.045 ～-0.052, P ＜ 0.05 ＝.Agreeableness, conscientiousness and neuroticism of NEO-FFI-R mediate the relationship between childhood abuse and anxiety of college students.The model fit indexes were x2/df = 0.546 ＜ 3.000, P = 0.460 ＞ 0.050, RMSEA = 0.001 ＜ 0.050, GFI = 1.000, AGFI = 0.998, NFI = 1.000, RFI = 0.998, IFI = 1.000,TLI = 1.002, CFI = 1.000.Conclusion Big five personality as mediated variable mediates the relationship between childhood abuse and anxiety of college students.

Objective To evaluate the effects of continuous intra-tracheal gas insufflation (TGI) during mechanical ventilation for protecting the juvenile piglets with acute lung injury (ALI) induced by endotoxin. Method Twelve healthy juvenile piglets were anesthetized and mechanically ventilated at 2 cmH2O PEEP with 10 cmH2O peak inspiration pressure. The piglets were challenged with lipopolysaccharide (LPS) and randomly (random number) assigned to two groups (n = 6 each): (1) piglets treated with mechanical ventilation alone (group MV) and (2) piglets treated with TGI by continuous airway flow of 2 L/min (group TGI). FiO2 was set at 0.4 to avoid oxygen toxicity, and the piglets were continuously monitored with an oxygen analyzer. Results Tidal volume, ventilation efficacy index and mean airway pressure were significantly improved in piglets of TGI group (P < 0.01 or P < 0.05). Four hours after ALI, pH decreased to below 7.20 in piglets of MV group, and was higher in piglets of TGI group (P < 0.01). Similarly, PaCO2 was stable and was significantly lower in piglets of TGI group than that in piglets of MV group (P < 0.01). PaO2 and PaO2/FiO2 increased in piglets of TGI group (P < 0.05). There were no significant differences in heart rate, respiraaatory rate, mean arterial pressure, central venous pressure, dynamic lung compliance and mean resistance of airway between two groups. Lung histopathological changes showed severe inflammation,and intra-alveolar hemorrhage and interstitial patchy hemorrhage were ameliorated and the lungs were more homogenously expanded in piglets of TGI group. Conclusions Continuous TGI during MV can significantly improve gas exchange and ventilation efficacy, and may provide a better treatment for acute lung injury.

BACKGROUND:Traditionally, forced expiratory volume in one second (FEV1) was used to evaluate exercise response of patients with asthma; however, patients obviously had panting after exercise, so FEV1 was affected commonly. Impulse oscillometry (IOS) is a new technique for measuring respiratory impedance that do not require maximal inspiration and forced expiration.OBJECTIVE: To study airway resistance with IOS before and after exercise in healthy and asthmatic patients and investigate the significance of exercise excitation and IOS assessment.DESIGN: Synchronically non-randomized case contrast study.SETTING: Department of Respiratory Medicine, East Hospital Affiliated to Tongji University.PARTICIPANTS: A total of 14 male patients with bronchial asthma who were regarded as the asthmatic group were selected from Department of Respiratory Medicine of Shanghai East Hospital from January to October 2006. They were in a clinical stationary phase. Another 14 male healthy subjects were selected as the control group and ages of all subjects ranged from 29 to 50 years. All subjects provided the confirmed consent.METHODS: IOS was used to measure basic value of respiratory resistance, and then subjects underwent exercise challenge. Nose of subjects was clipped breathing through mouth. Within 3-4 minutes, heart rate was increased to 90% and maintained for 6 minutes during challenge. Respiratory resistance was repeatedly measured at 1, 5, 10, 15 and 20 minutes after exercise, including airway hyperresponse (AHR), total respiratory resistance, central resistance, peripheral resistance and resonance frequency at 5, 20 and 35 Hz of pulse frequency, elasrtic resistance and inertia resistance (X5 and X35) at 5 and 10 Hz of pulse frequency. In addition, difference of AHR at 5 and 35 Hz was calculated, and change ratios of both Rcentral and Rperipheral were calculated as (highest value after exercise-baseline value)/baseline value × 100%.MAIN OUTCOME MEASURES: Basic value of respiratory resistance by using IOS and exercise challenge test.RESULTS: All 14 patients with bronchial asthma and 14 healthy subjects were involved in the final analysis. Peripheral resistance (Rperiphera) was significantly higher than central resistance (Rcentral) in asthmatic patients (P ＜ 0.01). The maximal increase of respiratory impedance occurred from 5 minutes to 10 minutes after exercise in asthmatics. Resonance frequency (Fres) of asthmatics before and after exercise was significantly increased than that of controls (P ＜ 0.01).Change ratios of Fres from asthmatics were higher than that from control group (P ＜ 0.01). After challenge, R5, R5-R20,Zrespir and X5 from asthmatics changed significantly than that from controls (P ＜ 0.01). The increment change value of After exercise Zrespir increased significantly, because obstruction of small bronchi during expiration and impedance increased abruptly. Air trapping was expressed in VT-Zrespir graph in 57.1% patients. There was no difference in the VT-Zrespir graph of controls before and after exercise.CONCLUSION: The main site of airflow obstruction was in small airways in asthmatics after exercise challenge. The general acceptance of IOS method was good among the asthmatic patients. The airway response of exercise challenge may be assessed more accurately with IOS that do not require a maximal inspiration and forced expiration.
