Background and purpose:Cancer-related pain is one of the most important symptoms of patients with advanced cancer. Chemotherapy sometimes induces peripheral neuropathy and pain. These symptoms seriously affect patients’ quality of life. Cancer pain assessment is now achieved by the subjective scales of patients, but lacking objective measurement. In this study, we used the neurotic electrophysiological method by way of PainVision system (PV system) to evaluate cancer pain quantitatively to detect and analyze degree of chemotherapy-induced neuropathy. Methods:We obtained numerical rating scale (NRS) scores from patients receiving analgesics and calculated the PainRatio from PV system at the same time. Then we analyzed the relationship between NRS and PainRatio scores. We detected current perception threshold (CPT) levels of patients receiving chemotherapy to ifnd the correlation between chemotherapy and CPT level, and attempt to evaluate chemotherapy-induced neuropathy.Results:PainRatio scores were linearly associated with NRS scores (Pearson correlation coeffcient=0.849,P<0.001). Patients with neuropathy symptoms got higher CPTs. However, no statistically signiifcant difference was observed between patients treated with oxaliplatin, paclitaxel and other agents.Conclusion:PainVision system can be used in cancer pain assessment quan-titatively, and be helpful in cancer pain assessment objectively. Patients with deifned neuropathy showed higher CPTs, indicating the potential clinical value of PV system in detecting and evaluating chemotherapy-induced neuropathy.

Objective To study the expression profile of microRNA (miRNA) and the roles in pathogenesis of acute liver failure in mouse model. Methods Eighty-five BALB/c mice were divided into four groups: 40 in model group of acute liver failure were intraperitoneally injected with Dgalactosamine (D-GalN) and lipopolysaccharides (LPS); 20 in D-GalN group were injected with DGalN only; 20 in LPS group were injected with LPS only; 5 in control group were injected with saline.Liver histology of mouse was observed at hour 0, 5, 7 of injection, and sera and liver tissues were collected at hour 0, 1, 3, 5, 7, 9 of injection. Meanwhile, levels of inflammatory factors [tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6)] in serum and liver tissue were detected by realtime polymerase chain reaction (PCR). Lock nucleic acid (LNA)-based miRNA microarray technology was used to detect the expression profile of hepatic miRNA, and the expression of miRNA was verified by real time quantification-polymerase chain reaction (RT-PCR). Mouse macrophage Raw264.7 cells were induced by LPS in vitro and the expressions of miRNA at different time points were detected.The comparison of means among groups was analyzed using one way ANOVA and the correlation were analyzed by Pearson and Spearman correlation. Results Microarray analysis found that the expression profile of miRNA during the acute liver failure changed dramatically. There were 97 miRNA in model group changed significantly compared with control group (P＜0.01), including 21 up-regulated and 27down-regulated at hour 5 and 7 of injection. Furthermore, the expressions of miR 146a and miR-155were verified by RT-PCR and found they both increased progressively over time after injection.Correlation analysis showed that miR-155 was well correlated with both TNF-α and IL-6 expressions.It was further found that miR-146a and miR-155 were both up-regulated in activated Raw264.7 cells in vitro. Conclusions The expression profile of miRNA changes during acute liver failure in mouse model. Inflammation associated-miR-146a and miR-155 are both up-regulated significantly, which indicatcs that they may play an important regulatory role in pathogenesis of acute liver failurc.

Rotavirus capsid protein Vp4 plays an important role in the virus adhering and entering the cells. In this study, a Vp4 gene cloned from a rotavirus strain TB-Chen was highly expressed in E.coli BL21 (DE3). The results of the Western blot showed that the protein possesses specific immuno-reactivities and can be specifically recognized by guinea pig antibodies against rotavirus strain SA11 or Wa. Some Vp4 dimers were formed during renaturation. These data obtained from this study provide a strong basis for further study on the structure and function of the Vp4.

OBJECTIVETo study the anti-immune inflammation efficacy and toxicity of Tripterygium wilfordii decoction, in order to provide experimental basis for studies on its "efficacy-toxicity" correlation.

METHODThe delayed hypersensitivity model was established by dinitrofluorobenzene in mice. Different doses of T. wilfordii decoction was administered for 5 consecutive days. The ear swelling inhibition ratio and the toxic action were observed. After the final administration, the biochemical indexes of PGE2, TNF-α, IL-2, ALT, AST, PA, TBA, TBIL in serum were detected, and the visceral indexes of heart, liver, spleen and kidney were measured.

RESULTThe DNFB-induced ear swelling could be notably inhibited by multiple oral administration of T. wilfordii decoction, with the ED50 and its 95% confidence limit of 0.34 (0.21-0.42) g x kg(-1). The contents of PGE2, TNF-α, IL-2 in serum decreased in a dose-dependent manner. The activities of serum AST, ALT, TBA, TBIL and the PA content reduced.

CONCLUSIONT. wilfordii decoction shows a significant anti-immune inflammation efficacy within the dosage range between 0.59 and 2.34 g x kg(-1) in a dose-dependent manner. With a certain hepatotoxicity, high dose (2.34-4.68 g x kg(-1)) of T. wilfordii decoction can cause substantial liver injury, with a dose dependence in liver function index. Therefore, the efficacy and toxicity of T. wilfordii is dose dependent, which provides reference for preventing adverse drug reactions in clinic and developing early-warning schemes and ensure the clinical medication safety of T. wilfordii.

BACKGROUND: Epidemiologic studies have shown an association between higher insulin levels and coronary artery disease, and metabolic studies have associated insulin resistance and compensatory hyperinsulinemia with non-insulin-dependent diabetes mellitus, hypertension, obesity,and lipid disorders.OBJECTIVE: To investigate the relationship between insulin resistance (IR) and erythrocyte insulin receptors (EIRs) in the patients with cerebral infarction (CI).DESIGN: Case-control trial.SETTING: Department of Neurology, China-Japan Union Hospital of Jilin University.PARTICIPANTS: From January 2004 to October 2004, 40 patients with CI, who were in-patients in China-Japan Union Hospital of Jilin University,were selected for the study. Meanwhile, 30 healthy doctors or nurses were recruited as normal controls.METHODS: The levels of blood glucose and serum insulin under fasting and 2-hour after oral glucose tolerance test (OGTT) were detected in the 40 patients with CI and 30 healthy doctors or nurses. Fasting blood glucose multiplied by fasting serum insulin was insulin resistance index (IRI). The number of insulin receptors and their binding affinity on every erythrocyte were determined using modified Gambhir's method. The correlation between the number of EIRs and IRI was analyzed.MAIN OUTCOME MEASURES: Comparison of CI group with controlRESULTS: Data of 40 patients with CI and 30 controls were analyzed, and under fasting and 2-hour after OGTT: The level of serum insulin under fasting and blood glucose, serum insulin at 2-hour after OGTT in CI group were higher than those in normal group [(13.30±5.15), (9.85±4.36) mU/L,(8.27±1.65), (6.32±1.37) mmol/L, (75.21±21.12), (28.26±6.31)mU/L,P ＜ 0.01,EIRs: The number of insulin receptors with high and low affinity and maximum specific binding rate in the patients with CI were significantly less than those in normal group [20.30±4.50, 23.80±4.10; 2 223.80±509.30,2 610.10±435.10; (10.62±3.55)%, (13.21±2.94)%, P ＜ 0.01]. Multiple linear regression analysis and correlation analysis showed the numbers of two types of EIRs in the patients with CI were negatively correlated with IRI (r=-0.458, -0.439, P ＜ 0.01, both).CONCLUSION: Insulin resistance can lead to cerebral infarction. Decrease in insulin receptors may play an importance role in cerebral infarction induced by insulin resistance.
