Objective To approach the capacity of erythrocyte regulating IL-8 in patients with primary hepatocarcinoma (PHC) by a new experimental system of hemaimmune. Methods 0.2ml suspension of cancer cells (S180: 5?10~6/ml) or NS were added into 0.2ml anticoagulant suspension of whole blood cells or leukocytes and 0.3ml plasma, then incubated for 1 h at 37℃. The content of IL-8 was determined by ELISA. Results In the patients with PHC, the IL-8 levels (pg/ml) in experimental and control groups of whole blood cells, and in experimental and control groups of leukocytes were 376.35?243.96, 353.64?271.92, 461.27?277.11 and 424.97?278.93, respectively; while in the normal human, they were 11.36?6.93, 4.98?4.35, 29.41?30.66 and 20.77?24.20, respectively. In the patients with PHC, the activation rates of cancer cells in the experimental groups of both whole blood cell and leukocyte were 0.22?0.24 and 0.25?0.53, respectively; while in normal human, they were 2.49?2.33 and 0.75?0.21, respectively. In the patients with PHC, the IL-8 adsorption rate of erythrocyte in both experimental and control groups of whole blood cell were 0.22?0.18 and 0.17?0.33, respectively; while in normal human, they were 1.18?2.29 and 0.86?0.49, respectively. The IL-8 activated rates of erythrocyte in the patients with PHC was much lower than in the normal human (P

Objective To evaluate the clinical value of 18FDG PET/CT in the diagnosis of lymph node metastasis and evaluation of node staging for esophageal carcinoma. Methods A prospective study was performed to access whether 18F FDG PET/CT can improve the diagnostic accuracy in lymph node metastasis for patients with esophageal carcinoma, 30 patients underwent esophagectomy with extensive dissection of lymph nodes. PET/CT findings were compared with that of CT. Results The pathological examination confirmed metastasis in 22 patients and 49 out of 243 excised lymph nodes. In PET/CT analysis, the sensitivity in the detection of lymph node metastasis was 93.9%, specificity was 91.2%, with a diagnostic accuracy of 91.8%. The positive and negative predictive value was 73.0% and 98.3%, respectively. CT resulted in a sensitivity of 40.8%, specificity of 96.9%, accuracy of 85.6%, the PPV was 76.9% and NPV 86.6%, respectively. The difference of sensitivity (P

OBJECTIVE To investigate the incidence of integrons in Pseudomonas aeruginosa strains isolated from blood samples in Peking University People′s Hospital and to analyze the correlation between integrons and drug resistance of P.aeruginosa.METHODS Forty-two strains of clinically isolated P.aeruginosa were collected.The antibiotics susceptibility was tested by K-B methods.Integrase gene of integron was amplified by PCR using degenerate primers.The integrons were classified by restriction fragment length polymorphism(RFLP) analysis of positive PCR products with Hinf Ⅰ restriction enzyme.RESULTS The drug-resistance rates of 42 strains of P.aeruginosa against 20 kinds of antibiotics ranged from 9.5% to 100%.Twenty-three strains were resistant to 12 kinds of antibiotics.Nineteen of the 42 isolates(45.2%) contained integrons,all of which were revealed as class Ⅰ of integrons by RFLP analysis.Neither class Ⅱ nor class Ⅲ of integron was detected.The positive percentage of integrons was increased by years.CONCLUSIONS Class Ⅰ integrons are widespread in isolates from blood samples in our hospital.The presence of integrons is closely associated with multi-drug resistance of P.aeruginosa.

OBJECTIVE:To observe the clinical efficacy and transdermal absorption of Suhong bone-penetrating massage drug for rheumatic arthralgia. METHODS:Suhong bone-penetrating massage drug(Chinese medicine) was applied in 300 cases with rheumatic arthralgia characterized by various symptoms such as bone spur, injury, scapulohumeral periarthritis, acute injury or chronic strain of articular surrounding soft tissue; Suhongtougu powder was used as control to treat another 120 cases with the same disease. The curative efficacies in two groups were compared. The effects of the effective components such as Muskone,Borneo Camphor,Menthol in Suhong bone-penetrating massage drug on the transdermal absorption of this preparation was investigated by transdermal test on mice. RESULTS:The total effective rate in the treatment group was 93.24% as compared with 80.00% in the control group, showing significant difference between two groups(P

Subjective: To observe apoptosis of the cells in oral sq uamous cell carcinoma(SCC) induced by cerulenin. Methods: SCC TCA-83 cells and fresh tissue of SCC of tongue from 5 patients were expos ed to cerulenin (10 mg/ml) for 24 hours, then the genosome DNA of the cells was extracted and electrophoresed; the fresh tissue of SCC was assessed by TUNEL labeling. Results: DNA gel electrophoresis showed typical apoptic DNA ladders from TCA-83 cells. The rate (%) of TUNEL-positive cells in cerulenin treated tissue of SCC was 29.0?2.6~40.6?16.2,that in the control 2 . 0?1.7~14.7?0.6 (P

Objective:To compare the effects of different anesthesia methods on stress hormones and hemodynamic changes in the patients with gynecological laparoscopic surgery. Methods:Retrospective analysis was carried out. Totally 145 patients with gynecolog-ical laparoscopic surgery were divided into two groups according to the anesthesia method, the control group with 72 cases was given routine remifentanyl propofol intravenous anesthesia, and the observation group with 73 cases was given routine propofol isoflurane com-posite anesthesia. Such hemodynamic indices as SBP, DBP and HR, and plasma NE, E, cort and AT II levels at different time points in the two groups were studied and compared, and adverse drug reactions were also observed in the two groups. Results:The BP and HR at T2 and T3 time point in the two groups were significantly lower than those at T0 time point (P<0. 05), and those in the obser-vation group were lower than those in the control group at the same time point(P<0. 05). The levels of NE, E, cort and ATⅡat T2 and T3 time point in the two groups were significantly higher than those at T0 time point (P<0. 05), while the increase in the observa-tion group was lower than that in the control group (P<0. 05). The incidence of adverse drug reactions (ADR), such as respiratory depression, hypertension, bradycardia and so on, and the total incidence of ADR in the observation group were both lower than those in the control group (P<0. 05). Conclusion:Compared with remifentanyl propofol intravenous anesthesia, propofol isoflurane composite anesthesia can keep the hemodynamic stability more effectively and reduce the stress reaction with fewer ADR and promising safety, which is worthy of wider application in clinics.
