Reasonable and effective compensation and incentive mechanism is key to maintaining and stimulating incentives of the staff.By means of defining the main problems and defects in the current hospital compensation system in China,performance management is used as the cornerstone for designing the public hospital compensation and incentive mechanism.Resource-based relative value scale(RBRVS) assessment system is called into play to build a compensation management system,which features workload as the basis,technical competency and risk assessment as the reference and balance scorecard as the means.This can build a fair,scientific and reasonable salary distribution system and performance evaluation system,which maximize incentives of the compensation system,and in the end maximize the economic and social benefits of the hospital.

Objective To investigate the proportion of follicular fluid CD56~+ natural killer (NK) cells to the total lymphocytes and the ac-tivated CD56~+ NK cells to the total CD56~+ NK cells. To provide an evidence for improving the clinical pregnancy rate in in vitro fertilization (IVF) treatment by regulating the function of NK cells. Methods Triple color flow cytometry was used to analyze the proportion of CD56~+ NK cells and activated CD56~+ NK cells in mature follicular fluid. The IVF treatment outcome was closely followed up. The relationship be-tween the proportion of CD56~+ NK cells and activated CD56~+ NK cells and the IVF treatment outcome was analyzed statistically. Results The proportion of CD56~+ NK cells and activated CD56* NK cells in mature follicular fluid of women who got pregnancy by IVF treatment was (15.57±3.10)% and (2.63±0.94)% respectively,while the proportion of the women who didn't get pregnancy was (19.12±5.37)% and (4.06±2.08)% respectively,which was significantly higher than the pregnant group(P< 0.05). Conclusion The women with lower propor-tion of CD56~+ NK cells and activated CD56~+ NK cells in mature follicular fluid of is easier to get pregnancy by IVF. An altered NK cells pro-file in follicular fluid could therefore influence fertility in IVF treatment outcome.

Objective To establish a sensitive,specific,simple and high-throughput method for detection of the epidermal growth factor receptor (EGFR) mutation in the plasma samples of patients with non-small cell lung cancer (NSCLS) by the use of mutant-enriched liquid chip (MEL) assay.Methods The specific probes for the EGFR exon19 E746-750 deletion,exon 21 L858R mutation and wild-type sequence were designed and coupled to the microspheres coding with different fluorescent dye.The probe coupling efficiency was verified by crossing hybridization test with biotin-labeled reverse sequence.A blood-based MEL approach which integrates a sensitive mutant-enriched PCR and quantitative high throughput liquid chip assay for assessment of EGFR mutations was developed.The sensitivity and specificity of MEL was further evaluated using the mixture with different copy numbers of mutant and wild-type plasmids as template.The mutations of exon 19 and 21 of EGFR gene in plasma samples from 201 patients with stage ⅢB or Ⅳ NSCLC who enrolled in the First Affiliated Hospital of Guangzhou Medical College from September 2008 to April 2010 were analyzed by both the MEL and the mutant-enriched PCR assay.The result comparison was made between direct sequencing and MEL in 50 cases whose EGFR gene type had been tested by MEL and mutantenriched PCR.The correlation of EGFR gene mutation and the response to the Geftinib treatment was analyzed in 16 patients with lung adenocarcinoma as well.Results The probes were successfully coupled to the microspheres encoding with different fluorescent dye,and could be specifically recognized by the corresponding target sequence.The MEL was capable of detecting as few as 10 copies of EGFR mutants (sensitivity was 0.1％).Among the enrolled 201 cases of advanced NSCLC,the detection rate of the EGFR exon19 E746-750 del and exon 21 L858R was 55.7％ (112/201) by MEL assay.Conpared with mutantenriched PCR[58.2％ (117/201)],the coincidence rate was 97.5％ (196/201).There was no statistically significant difference between the results of mutant-enriched PCR and MEL (x2 =3.20,P ＞ 0.05).The mutations detection rate was 22.0％ (11/50) by directing sequencing,which was significantly lower than by MEL[50.0％ (25/50),x2 =12.07,P ＜ 0.05].Among the 16 patients treated with Gefitinib,9 cases who had EGFR mutation showed a higher response rate(P =0.041)and prolonged progression-free survival (x2 =6.76,P =0.009) after the treatment compared to those 7 who without EGFR mutation.Conclusions A new method of MEL with accuracy,specificity,fast and high-throughput is established for the detection of EGFR 19 E746-750 deletion and exon 21 L858R mutations in plasma from advanced NSCLC patients.It has the ability to provide the most direct and valuable guidance for clinicians to make decision on EGFR tyrosine kinase inhibitors therapy in the advanced NSCLC paticnts.

Objective: Our aim was to study whether the cellular bronchoalveolar lavage fluid (BALF) profile was associated with the parameters of pulmonary function tests. Methods：Lung function tests and BAL were carried out in 18 untreated, non-smoking patients suffering from sarcoidosis and 18 normal subjects. Results：（1）Lung function tests were normal at rest in patients with sarcoidosis（P＞0.05）, the single breath carbon monoxide diffusing capacity decreased (P＜0.05)，and the small airway function decreased too (P＜0.05).（2）The percentage of lymphocytes in BALF of sarcoidosis increased comparing with the normal subjects（P＜0.01），and the ratio of CD+4 to CD+8 in BALF increased significantly in sarcoidosis（P ＜0.05）, furthermore, the increase of both the percentage of lymphocytes and the ratio of CD+4 to CD+8 in BALF of sarcoidosis were well nagatively correlated with the decrease of the percentage of DLCO (r=-0.67, P＜0.01 and r=-0.55, P＜0.05, respectively), the decrease of mid-expiratory flow at 50% of vital capacity (FEF50%) was well correlated with the increase of the percentage of lymphocytes in BALF of sarcoidosis (r=-0.54, P＜0.05). Conclusion：Pulmonary diffusing capacity（DLCO) was significently correlated with BALF lymphocyte phenotype，so was small airway function，and can act as the marker of activity of sarcoidosis.

Objective Through the investigation of the compliance and impact factors of prenatal check to the pregnant women,we aimed to supply the ideas and methods to improve antenatal care compliance. Methods This investigation used the questionnaire which was designed by the author to survey 100 pregnant women in class three level hospital in Guangzhou.The results underwent subsequent analysis. Results There were 68.4%of the pregnant women didn't finish the check.The average check times Wag only five.70.4%of them who were younger than 30 hadn't fulfilled seizure frequency rates,while 65.9%for who were older than 30(P＞0.05).The pregnant women with school-age≤9 and school-age＞9 who hadn't fulfilled seizure frequency rates were 83.3%and 50.0%.Irregular check rates were 59.3%、29.5%(P＜0.01).The floating population and the local population in the area of prenatal compliance results showed statistical difference.P＜0.01.The family whose income was higher than 3000 yuan per-month were better than those lower than 3000 yuan per-month about the antenatal check compliance(P＜0.05).More than 70% of pregnant women felt risk factors of pregnancy complications,their partners' support,local medical conditions and attitudes of medical staff had influence of their antenatal check compliance.Conclusions The compliance of the low education and low family income group is relatively low.For the affecting factors.how to improve the prenatal check compliance of such crowd is worthy of further study.
