Objective To explore the expression of CD14 and TLR4 ( Toll like receptor - 4) in peripheral blood monocytes during the different stage of cancer patients. Methods The expression of TLR4 and CD14 on peripheral blood monocytes was determined by flow cytometry in 50 healthy control group and 80 patients with malignant tumor who were divided into stable group and advanced group according to the change of the size of tumor measured by image and/or the outcome of tumor makers. Results No significant difference was found in the expression level of CD14 between the different stage of malignant tumor ( stable group and advanced group) and healthy controls [ (6. 1600% ? 2. 32217% ,5. 8629% ? 1. 91896% ) vs (5. 5580% ? 1. 42272% ) ]. The expression of TLR4 in stable group had no significant difference as compared with control group [ ( 10. 4444 ? 3. 16225 ) % vs (8. 8780 ? 5. 24612) % ]. The expression of TLR4 in advanced group was significantly higher than that in controls and stable group [ ( 14. 7286 ? 6. 95213 ) % vs ( (8. 8780 ? 5. 24612) % , ( 10. 4444 ? 3. 16225) % ) (P

Objective To explored the moderate effect of perceived organizational support on job burnout-health complaint relationship and job burnout-task performance relationship. Methods Maslach burnout inventory-general survey, the perceived organizational support scale, health complaint scale and task performance scale were used to test 458 teachers in colleges of Armed Police. Results Emotional exhaustion and cynicism were positively related to health complaint (r = 0. 616,0. 4377;P < 0. 01). Emotional exhaustion and cynicism indicated obviously predicted effect on health complaint(β =0.562, P<0. 01;β =0. 144, P<0.05). Reduced personal accomplishment predicted task performance obviously(β = -0.248, P<0.01). Hierarchical multiple regression showed perceived organizational support can regulate the relationship between emotional exhaustion and task per-formance(△R~2 =0.031, P<0.01). Conclusion Job burnout positively predicted health Complaint. The higher the job burnout was, the more seriously the health Complaint. Reduced personal accomplishment negatively predicted task performance. Perceived organizational support had moderate effect on emotional exhaustion and task performance relationship. It relieved the negative effect of emotional exhaustion on task performance.

Objective To investigate the relationship between CD+3CD28+T cell value and chemotherapeutic efficacy in patients with advanced digestive cancer. Methods 38 digestive cancer patients with distant metastatic lesion were included.10 healthy persons were as control group. The absolute counts of CD+3CD28+T cell were measured with flow eytometry in these patients before chemotherapy. All patients received chemotherapy, gastric cancer: DCF regimen (docetaxel plus tegafur and cisplatin, one cycle), colorectal cancer:. Folfox regimen (L-OHP plus tegafur, two cycles), esophageal cancer: mitomycin plus tegafur and cisplatin (two cycles), gallbladder or pancreatic cancer: gemzar plus tegafur and cisplatin (one cycle). According to WHO standard, the chemotherapeutic efficacy was determined, 38 patients were divided into three groups: CR+PR (complete remission plus partial remission), SD (stable of disease) and PD (progress of disease) group. Statistical analysis was used upon all data. Results There was no significant difference in value of CD+3CD28+ T cell between CR+PR group and control group (P=0.549). The value of CD+3CD28+ T cell in SD group and PD group were significantly decreased (P=0.002, P=0.000). The value of CD+3CD28+T cell in CR+PR group was more than that in PD group (P =0.001), while in SD group was more than in PD group (P = 0.044). Conclusion The efficacy is poor, if the value of CD+3CD28+ T cell in patients with advanced digestive cancer is less than that of in healthy persons in peripheral blood. Therefore, the value of CD+3CD28+ T cell is important for the early prediction of the efficacy before chemotherapy.

Objective To receive disinfection messages of sickbeds from nurse workstations and to reduce the periods of the request transfer.Methods The system transferred the request for replacing bed between wards and disinfection units by UDP messages,and informed the staff by active speaker and LCD screen.Results The time of replacing beds decreased significantly,so the wards were very satisfied with the disinfection units.Conclusion The system can reduce the time of replacing beds obviously and make the requests for replacing beds satisfied.

With the rapid development of proteomics technology,SELDI protein chip technology has become a powerful tool for proteomics with the capacity of gathering sample separation,purification,testing and data analysis together.As its convenience,high-throughput and high-sensitivity,as well as simple and fast analysis,SELDI technology plays an important role in the diagnosis and prevention of tumor.Here we re- view the basic principles,features and recent advances of this technology in digestive tumor.

Surgical resection has been accepted as a radical therapy for patients with colorectal cancer, but most of them will develop regional recurrence or distant metastasis. With the development and improvement of novel drugs and methods, they will bring survival hope to patients. In this article, we review the developments in chemotherapy for patients with advanced colorectal cancer.

Objective To explore the findings and clinical value of bedside ultrasonography in superior vena cava(SVC) syndrome in children after cardiac operations for congenital heart disease. Methods Bedside ultrasonography was performed on 6 children suspected of SVC syndrome after 5-38 hours[(22?11) hours] postoperatively,to view the structure and blood flow of SVC and its main branches. All the patients were reoperated as soon as diagnosed. Results Five children got severe SVC obstruction, marked with stenosis, turbulent, continuous and high velocity in SVC. Color Doppler flow imaging presented almost absence of flow due to nearly complete occlusion of the innominate vein in 1 child. Ultrasonographic diagnosis was confirmed by the reoperative findings. All the patients were cured by reoperation and discharged with normal ultrasonographic results. Conclusions Bedside ultrasonography can provide early and accurate diagnosis in children with SVC syndrome after cardiac operation.

Objective To explore the role of TGF-βand TGIF in the pathogenesis of endometriosis. Methods The expression of TGF-β and TGIF was detected by immunohistochemistry method in the ectopic and eutopic endometrium of 30 cases with endometriosis (ec-topic endometrium group and eutopic endometrium group) and in the normal endometrium of 40 cases without endometriosis (control group). Result The expression of TGF -β in ectopic endometrium group was significantly higher than that in eutopic endometrium group and control group (P < 0.05). There was no significant difference in the expression of TGF- βbetween eutopic endometrium group and control group(P > 0.05). The expression of TGIF in ectopic endometrium group was significantly lower than that in eutopic endometrium group and control group( P <0.05). There was no significant difference in the expression of TGIF between eutopic endometrium group and control group(P > 0.05). There were negative correlation between the expressions of TGF - β and TGIF in ectopic endometrium group and eutopic endome-trium group(rs= - 0.769, - 0.549, P < 0.05). Conclusion The abnormal expression of TGF-β and TGIF in ectopic endometrium of pa-tients with endometriosis may be associated with the genesis and progression of endometriosis.

Objective By surface-enhanced laser desorption / ionization time-of-flight mass spectrometry(SELDI-TOF-MS), the serum pmteomic fingerprints related with the changing of malignant tumor patients' serum glucose after chemotherapy was selected and constructed as an predictive model. Methods By SELDI-TOF-MS, the serum of 182 malignant tumor patients who had received chemotherapy were tested, and the pmteomic fingerprints were received. After 2 years follow-up, all the patients were divided into 3 groups: the euglycemia group(136 people), the carbohydrate tolerance abnormality group(27 people), and the diabetes mellitus group (19 people). The proteomic fingerprints were analyzed by Biomarker Wizard Software and the idio-proteomic fingerprint of protective models were constructed by BPS (biomarker pattern software). Results The diagnosis model composed with 2 proteins (M/Z values were 5298 and 9608) could classify the carbohydrate tolerance abnormality group, and the diabetes mellitus group correctly. In the test model, the sensitivity and specificity were 81.48 %(22/27) and 100.00 %(17/17) respectively, the accuracy was 88.64 % (39/44). The diagnosis model composed with 3 proteins (M/Z values were 10324, 2761 and 4084) could classify the diabetes mellitus group and the euglycemia group correctly. In the test model, the sensitivity and specificity were 62.35 %(53/85) and 88.24 %(15/17) respectively, the accuracy was 66.67 %(68/102). The diagnosis model composed with 6 proteins (M/Z values were 5895,6010,6099,3930,5430 and 2495) could classify the diabetes mellitus group and the the carbohydrate tolerance abnormality group correctly. In the test model, the sensitivity and specificity were 77.65 %(66/85) and 96.30 %(26/27) respectively, the accuracy was 82.14 %(92/112). Conclusion SELDI-TOF-MS could be utilized to analyze protein profiling in screening serum glucose changing-related biomarkers and developing diagnostic and predictive patterns, and the developed patterns may be used to predict the changing of serum glucose after chemotherapy in malignant tumor patients.
