Objective To study the induction of IL-6 on expression and activity of tissue factor (TF)in peripheral blood monocytes(PBMCs).Methods rhIL-6 100 ng/L and rhIL-6 100 ng/L+ rhIL-6 MoAb 10?g/L were used respectively to stimulate the PBMCs for 24 h,PBMCs without any stimulation as control group,to study the changes of antigen content,mRNA expression and the ac- tivity of the TF.Results The antigen content,mRNA expression and activity of TF were increased significantly in 100 ng/L rhIL-6 group as compared with rhIL-6 100 ng/L+rhIL-6 MoAb 10?g/L and control groups(P＜0.01).Conclusions rhIL-6 can induce the increase of antigen expression,activity and mRNA expression in PBMCs,and these effects can be suppressed successfully by rhIL-6 MoAb. This study demonstrated that there was potential relations between cytokines and thrombogenesis, which may play an important role the pathogenesis of chronic rejection.

The relationship between vascular endothelial growth factor-C (VEGF-C)/vascular endothelial growth factor receptor 3 (VEGFR-3) expression and clinicopathologic features of the patients with non-small cell lung cancer (NSCLC) was investigated. The expression of VEGF-C and VEGFR-3 was assessed in 65 patients with NSCLC by immunohistochemistry. The significance of VEGF-C and VEGFR-3 expression was analyzed statistically. The results showed that VEGF-C and VEGFR-3 were highly expressed in cytoplasm and membrane in lung cancer tissues with the positive rate being 55.4 % and 52.3 % respectively, while there was no expression in the normal lung tissues. The expression of VEGF-C was significantly increased in adenocacinoma as compared to other types of NSCLC (P<0.05). The VEGFR-3 expression was closely related with lymph node metastasis (P<0.01) and TNM stage (P<0.05). There was a positive correlation between the VEGF-C and VEGFR-3 expression in NSCLC patients (r=0.658, P<0.01). It is suggested that VEGFR-3 plays an important role in the lymphatic metastasis of NSCLC. The interaction between VEGF-C and VEGFR-3 may be deeply involved in the mechanism of lung cancer metastasis.

Objective: To determine if different methods of anesthesia and analgesia will influence the incidence of early postoperative cognitive dysfunction (POCD) after non-cardiac surgery in the elderly. Methods: One hundred and three elderly patients undergoing elective abdominal surgery were randomly allocated to receive either general anesthesia followed with postoperative intravenous analgesia (general anesthesia group, 53 cases) or combined general-epidural anesthesia followed with postoperative epidural analgesia (combined general-epidural anesthesia group, 50 cases). Cognitive function was assessed preoperatively and 7 days postoperatively using a battery of nine neuropsychological tests. A postoperative deficit in any test was defined when decline by more than or equal to 20% of the preoperative value of that test occurred. Any patient showing deficit in 2 or more tests was defined as having postoperative cognitive dysfunction. Results: Ninety-two patients completed both preoperative and postoperative neuropsychological tests. On day 7, POCD occurred in 20/45 patients (44.4%) in the general anesthesia group and in 23/47 patients (48.9%) in the combined general-epidural anesthesia group. No significant difference was found between the two groups. Logistic regression analysis showed that short duration of education and operation of general surgery were independent risk factors of the occurrence of early POCD. Conclusion: Early POCD occurred in 46.7% of the elderly patients undergoing abdominal surgery. However, there was no significant difference between the effects of two different methods of anesthesia and postoperative analgesia on the incidence of POCD. Short duration of education and operation of general surgery were risk factors of early POCD.

Nuclear factor(NF)-κB is widely expressed in various types of tissue cells. Abnormal activation of NF-κB signaling pathway can lead to the initiation and progression of asthma,chronic ob?structive pulmonary disease(COPD)and other lung inflammatory diseases,but inhibition of its activity can effectively alleviate the occurrence and development of these diseases. In this paper ,we review biological characteristics of NF-κB,role of NF-κB signaling in asthma,COPD and other inflammatory lung diseases,and potential application of NF-κB inhibitors in clinical treatment of these inflammatory lung diseases. It will provide a valuable reference for further study on pathogenesis,prevention,and control of lung inflammatory diseases.

BACKGROUND:Hyaluronic acid or compound betamethasone for treatment of knee osteoarthritis can reduce inflammatory reactions in the joints, relieve pain, and protect the function of the knee joint. OBJECTIVE:To investigate the clinical efficacy of intra-articular injection of hyaluronic acid combined with compound betamethasone on middle-stage knee osteoarthritis as wel as protective effect on joint function. METHODS:A total of 100 patients with II, III knee osteoarthritis were randomly divided into two groups: intra-articular injection of hyaluronic acid (2 mL) as control group and intra-articular injection of hyaluronic acid (2 mL) combined with compound betamethasone (1 mL) as testing group. The intra-articular injection was carried out once a week, totaly for consecutive 5 weeks. Visual analog scale score, Lysholm knee joint score and erythrocyte sedimentation rate were compared between two groups before and after treatment. RESULTS AND CONCLUSION:After treatment, the visual analog scale score, Lysholm knee joint score and erythrocyte sedimentation rate were improved significantly in the two groups as compared with those before treatment (P < 0.05); in addition, these parameters were al better in the testing group than the control group (P < 0.05). No systemic adverse reactions occurred in the two groups. These findings indicate that the intra-articular injection of hyaluronic acid combined with compound betamethasone can reduce inflammatory reactions, relieve pain, and improve joint function.

Objective To investigate the prevalence and related factors of sexual dysfunction (SD) in patients with Parkinson's disease.Methods A total of 411 patients with Parkinson' disease in Nanjing Brain Hospital were analyzed retrospectively.The ICD-10 diagnostic criteria for SD was used to evaluate SD.The Unified Parkinson's Disease Rating Scale (UPDRS) part Ⅲ, Hoehn and Yahr (H&Y) staging, Non-motor Symptoms Questionnaire (NMS-Quest), Parkinson's Disease Sleep Scale (PDSS), Hamilton Anxiety Rating Scale (HAMA), Hamilton Rating Scale for Depression (HRSD) and Montreal Cognitive Assessment (MoCA) were used to evaluate patients.Results SD was found in 145 (35.3 ％) patients and the prevalence was higher in male than in female.Patients with SD had older age, longer duration, severer motor symptoms, and higher scores of UPDRS-Ⅲ, HAMD, HAMA and NMS-Quest (all P＜0.05).In male patients, SD was positively associated with age, duration of disease, UPDRS-Ⅲ , H-Y stage, HAMD, HAMA and NMS (r=0.127, 0.303, 0.240, 0.236, 0.181, 0.221 and 0.302, all P＜0.05).In female patients, SD was positively associated with duration of disease, HAMD, HAMA and NMS (r=0.194, 0.163, 0.189 and 0.178, all P＜0.05).The forward binary Logistic regression analysis indicated that female gender (OR=0.539, P＜0.05), duration of disease (OR=1.133, P＜0.05), NMS (OR=1.104, P＜0.05) and history of exposure to heavy metals (OR=5.268, P＜0.05) were associated with SD.Conclusions SD is a common complication in patients with Parkinson's disease, and a great attention should be paid to its screening and diagnosis.
