Objective:To investigate job burnout status of doctor and nurse in China. Methods: 218 doctors and nurses were assessed by MBI-HSS. Results: 42.1% subjects got high or moderated scores on Emotional Exhaustion, 22.7% subjects got high or moderate scores on Depersonalization and 48.6% subjects got low or moderate scores on personal accomplishment. Female subjects got higher scores on Emotional Exhaustion than male subjects Compared with.subjects with higher level education, subjects with lower level education got higher scores on Emotional Exhaustion, however, lower scores on Personal Accomplishment.Conclusion:Some subjects are found to experiences job burnout. To prevent or cure job burnout, more attention should be paid to female and persons with lower level education.

Objective To investigate the pathologic base of breast cancer malignant halo.Methods The status of margin of 80 cases confirmed breast nonspecific invasive ductal cancer by pathology were determined preoperatively.80 cases were divided into two groups:malignant halo group and non malignant halo group.The estrogen receptor (ER),progesterone receptor (PR),human endothelial growth factor receptor (CerB-2),nuclear protein antibodies (Ki-67) expression were detected by immunohistochemical method.The histological grade,mitotic count and documented tumor size,patient age and the number of lymph node metastases,breast cancer margin on pathology were observed.Halo tissue were drawn from specimens and the tissue structure were observed.Results Ki-67 expression in malignant halo group were significantly lower than those in non malignant halo group.The observing results of the margin status of breast cancer on ultrasound and pathology were consistent.Halo tissue was mainly composed of fatty tissue and scattered clumps of cancerous tissue,fibrous tissue,normal lobular and tubular.Conclusions Malignant halo is a special manifestation of breast cancer on gray-scale ultrasound.

Obiective To investigate the effect ofisoflurane on expression of IL-1β mRNA,IL-6 mRNA and TNF-α mRNA in the hippocampus of immature rats.Methods sixty-four 7-clay-old SD rats were randomly assigned into 2 groups(n=32 each):control group(group C)and isoflurane group(group S).group S was exposed to 1.5% isoflurane for 6 h while group C to air.Fore animals were killed before anesthesia(T0,baseline),at 2,4,6 h(T1-3)of isoflurane anesthesia and 4,6,12 and 24 h after anesthesia(T4-7).The hippocampi were immediately removed for determimation of the expression of IL-1β mRNA,IL-6 mRNA and TNF-α mRNA by RT-PCR.Results Compared with group C,the expression of IL-1β mRNA at T1-5,IL-6 mRNA at T2.3 and TNF-α mRNA at T1-6 in the hippocampus was upregulated in group S.Conclusion The expression of IL-1β mRNA,IL-6 mRNA and TNF-β mRNA was elevated in the hippocampus of immature rats after being exposed to isoflurane.

To investigate the monitoring of acute rejection of porcine pancreaticoduodenal allografts, 12 pigs were subjected to pancreaticodudenal allografts, among them 6 pigs received triple therapy for 7 days. Serial biopsies were performed in pancreas allografts for diagnosis of pancreatic acute rejection. Amylase secretion was determined periodically.The levels of TNF ? and NO in serum were serially monitored.The results showed that amylase secretion decreased,TNF ? and NO concentration in serum increased significantly as acute rejection was detected histo pathologically in pancreatic grafts. It suggested that monitoring of amylase secretion, serum TNF ? and NO concentration could be used to decide the proper time of performing biopsy for early diagnosis of acute rejection of the pancreas allograft.

Objective To study the CT manifestations of metastatic lymph node of thyroid carcinoma. Methods CT appearances of metastatic lymph node of thyroid carcinoma proved by surgery and pathology in 108 patients were reviewed. Results Of these 108 cases, metastatic lymph nodes were located at superoir and middle internal jugular chain(n=76), inferior internal jugular chain and super clavicular region(n=86), tracheoesophageal groove(n=52), and superior mediastinum(n=17). Of 84 thyroid papillary carcinoma patients, the attenuation of metastatic lymph nodes were similar to that of normal thyroid gland(n=16), with cystic formations (n=24), intracystic high attenuation papillary-like nodules (n=18), and fine granular calcifications (n=11). Of 24 follicular carcinoma, medullary carcinoma, and clear cell carcinoma patients, 17 cases had significant homogeneous or heterogeneous enhanced nodes, and the attenuation was the same as primary or recurrent thyroid tumors. Conclusion For thyroid carcinoma, the most common locations of metastatic lymph nodes were internal jugular chain, tracheoesophageal groove, and superior mediastinum regions. Marked enhancement similar to normal thyroid gland, cystic formations with intracystic high attenuation papillary-like nodules, and fine discrete granular calcifications were the characteristic manifestations of metastatic lymph node of papillary carcinoma. Marked homogeneous or heterogeneous enhancement after contrast administration and the same attenuation as the primary or recurrent thyroid tumor were found in follicular carcinoma, medullary carcinoma, and clear cell carcinoma metastases.

Objective:To explore the relationship between work-family conflict and job burnout of doctors and nurses.Method:218 doctors and nurses were assessed by Work-Family Conflict Scale and Maslach Burnout Inventory.Result:Hierarchical regression indicated that the work-family conflict was a powerful predictor of job burnout beyond demographic variables, 37% variance of Emotional Exhaustion was explained by work-family conflict, 18% variance of Depersonalization and 12% variance of Personal Accomplishment were also explained by work family conflict. Conclusions:The work-family conflict is an important, may be the most influencing factor on job burnout in medical staffs.

Objective:To evaluate the efficacy of drug abuse prevention and treatment and the needs of drug users.Method:A multi-center survey was carried out with a self-designed questionnaire in 10 compulsory detoxification centers among 2400 drug users.Results:The results of the survey indicate that 76.2% of the subjects had never received any drug abuse prevention education before they using drugs. However, 53.6% of the subjects who received drug abuse prevention education thought that the promotion and education are not helpful or hardly helpful. Drug abusers were basically satisfied with most "software" and "hardware" services of the present compulsory drug abuse center. What should be improved is the effectiveness of treatment. Meanwhile, Drug abusers thought that the most urgent needs were: learning skills to prevent relapse; helping to improve living surrounding and helping to find jobs etc.Conclusion:The coverage of the present drug abuse prevention education is not wide enough and need to be improved in its effectiveness and orientation. In order to make drug abuse treatment more effective and meet drug abusers' needs, multi-department and cross-discipline cooperation, exploration and efforts from the whole society are necessary.

ObjectiveTo observe the effect of digital auditory activation and touching intervention on infants with cerebral dysfunction.Methods388 infants with perinatal high-risk factors and abnormal result of Denver Development Screening Test (DDST) were randomly divided into group A (n=135), group B (n=128) and group C (n=125), and treated with digital auditory activation combined with touching (group A), simple touching (group B) and simple drug (group C) with 10 days as a course. All infants were tested with DDST after one therapeutic course, and tested again with DDST after the infants of group B and group C treated continuously for six therapeutic courses; and all infants were assessed with the Gesell development quotient (DQ) after six months.ResultsAfter one therapeutic course, normal rate of DDST was 71.11% in group A, 26.69% in group B and 20.00% in group C. After six therapeutic courses, that was 90.37 % in group A, 62.50 in group B and 40.00% in group C. After six months, the children with the Gesell DQ over 86 scores was 125 (92.60%) in group A, 90 (70.31%) in group B and 62 (49.60%) in group C. There were significant differences among three groups ( P<0.01).ConclusionThe digital auditory activation combined with touching has short therapeutic course and high efficacy, so it is a good therapeutic method for infants with cerebral dysfunction.

Objective To detect apoptosis of transplanted lung adenocarcinoma cells in nude mice after 125I brachytherapy by 99Tcm-Annexin V combined with diffusion weighted MRI (MR-DWI).Methods Twenty-five BALB/c-nu nude mice models subcutaneously transplanted with A549 cells were divided into experimental group (EG,n=13) and control group (CG,n=12) by random number table method.One 125I seed with apparent activity of (24.8±6.3) MBq was implanted into each mouse in EG,while CG underwent cold seed implantation.Both of 99Tcm-Annexin V imaging and MR-DWI were performed within 7-10 d after brachytherapy,then all mice were sacrificed and tumor cell apoptosis was detected by terminal oxynucleotidyl transferase mediated dUTP biotin nick end labeling (TUNEL) immunofluorescence,Survivin expression was assayed by SP.Two-sample t test,x2 test and Pearson correlation analysis were used for data analysis.Results Positive rate of cell apoptosis by 99Tcm-Annexin V imaging was 69.2％(9/13) and 8.3％(1/12) respectively in EG and CG (x2 =12.73,P＜0.01).The uptake ratio of 99Tcm-Annexin V,apparent diffusion coefficient(ADC) value and apoptosis index(M) of the tumor in EG were 2.91±0.85,(2.03±0.44)×10-3 mm2/s and (49± 18) ％,respectively,which were significantly higher than those of CG (1.26 ± 0.37,(1.29 ± 0.21) ×10-3 mm2/s and (11±4)％ respectively,t=5.930,5.452,7.606,all P＜0.05).Survivin expression in EG and CG was (46± 13) ％ and (15±7) ％ respectively (t =5.158,P＜0.05).The value of ADC was correlated with AI and uptake ratio(r=0.756,0.788,both P＜0.05).Uptake ratio was correlated with AI (r=0.754,P＜0.05),while Survivin expression was negatively correlated with AI (r =-0.772,P＜0.05).Conclusions Down-regulation of Survivin expression may play an important role in apoptosis induced by 125I brachytherapy.99Tcm-Annexin V combined with MR-DWI could effectively evaluate apoptosis of lung adenocarcinoma cells in a non-invasive way,thus it might be helpful in evaluation of early efficacy of 125I brachytherapy.
