Epistaxis is a common otorhinolaryngological emergency with complex etiological factors and varied clinical manifestations. The key to epistaxis treatment is accurate diagnosis and adequate hemostasis. Electrocoagulation is a reliable, safe and effective treatment for epistaxis. However, there are still several deficiencies in application of the commonly used electrocoagulation surgical products. This paper introduces a new type of radiofrequency head incorporating the dynamic circulatory functions of drip, irrigation, hemostasis and aspiration. We aim to achieve noninvasive, effective and accurate hemostasis in the treatment of epistaxis or nasal sinus surgery.

Objective:To examine the expression of TRAF 6 in ovarian carcinomas ,discuss the relation between expression level and clinical characteristics of ovarian carcinomas and study the clinical significance .Methods: Specimens from 102 patients with ovarian carcinomas managed in our hospital between Augest 2001 and December 2009 were included in this study .Immunohistochemical staining was used to detect the expression of TRAF 6 in ovarian carcinomas and normal tissues .All the specimens were confirmed by pa-thology for ovarian carcinomas and normal tissues by HE staining .Then, the correlation between the expression and clinical characteristics of patients was analyzed .Furthermore ,survival analyses were performed according to the Kaplan-Meier method.Results:The positive expression rate of TRAF 6 in ovarian carcinomas and normal tissues was 68.6% and 20.5%, respectively.TRAF6 expression was significantly associated with tumor stage and distant metastasis ( P<0.05 ) .According to the survival analysis of 102 ovarian carcinomas patients ,cases in the TRAF6 low-expression group showed poorer overall survival rate when compared with low -expression group ( P<0.001 ) .Conclusion: These results indicate that the expression of TRAF 6 was closely related with in the progression of ovarian carcinomas and may have clinical utility in the prediction of prognosis of ovarian carcinomas .

The statement on the depth of needle insertion is collected from Neiiing (nternal Classic) and Nanjing (Classic of Medical Problems) and the relationship of it is discussed with meridians, diseases, symptoms, location of sickness, qi and blood changes in human body, time, layers of needle insertion, reinforcing and reducing of acupuncture, etc. The factors are explored for the determination of the puncture depth, which provides the important guidance for the depth of insertion, needling sensation, reinforcing and reducing manipulations, acupuncture effect and the improvement of acupuncture efficacy. The complex and mystery of acupuncture technique focus on the control of insertion depth. In clinical practice, the increase of needle insertion depth may not induce the equal increase of efficacy. The depth of needle insertion is rather relevant with stimulation at the effective acupoint in the effective layer.

An analysis on the human resources, equipments and budgets of the township hospitals in Wenzhou City discovered the following setbacks: Changeable management system, poor positioning of their functionality, difficulty to play their roles, insufficient funding, inadequate infrastructure, slow development, lack of medical technicians, low level of medical services, and lack of development momentum. Based on these findings, the author proposed the following to upgrade their functionality and promote their development: Clearly positioning their functionality, improving the financial assurance mechanism, deepening system reforms in these hospitals, and further clarifying job divisions.

To summarize the risk factor,pathogenic bacteria,medical and prevention progress of ventilator-associated pneumonia.It is beneficial to avoid the risk factor of ventilator-associated pneumonia,and to reduce morbidity and mortality.

Objective　To further investigate the balance (relative presence) of Th1 and Th2 subsets at the sites of rheumatoid inflammation,and to understand how about the expression of IL-18 in patients with rheumatoid arthritis (RA),and what the relationship exists between expression of IL-18 and rate of Th1/Th2 in RA,and between IL-18 level and activity of the disease.Method　Expression of IFN-γ,IL-4,and IL-18 mRNA in peripheral blood mononuclear cells (PBMC) from 16 patients with RA and 15 healthy subjects was detected by semi-quantitative RT-PCR.Results　① PBMC from patients with RA was found to contain greater levels of IL-18 mRNA than that from healthy subjects (P＜0.01).② IL-18 mRNA levels were correlated with IFN-γ mRNA (relative coefficients:r＝0.836,P＜0.05).③ IL-18 mRNA levels were associated with the disease activity as assessed by levels of erythrocyte sedimentation rate (r＝0.753,P＜0.05).Conclusion　IL-18 is among a matrix of inflammatory cytokines produced abundantly in patients with RA and is associated with induction of IFN-γ and activity of the disease.

Objective To evaluate the medium-term follow-up outcomes of treatment of chronic scaphoid nonunion with vascularized bone graft based on 1, 2 intercompartmental supraretinacular artery.Methods From February, 1995 to November, 2006, 13 cases of chronic scaphoid nonunion were treated with vascularized bone graft based on 1, 2 intercompartmental supraretinacular artery in our hospital. Nine cases were complicated with avascular necrosis of the proximal pole. The interval between injury and treatment averaged 22. 2 months. The nonunions were stabilized by screw or external fixator. Procedures of arthrolysis were applied and early wrist mobilization was initiated under the protection of external fixator. Radiographic finding and Mayo scoring system were used to evaluate the clinical outcomes. Results The mean time of follow-up was 82.9 months. The union time for the 13 cases averaged 11.2 weeks. At the final follow-up,there were 3 excellent, 8 good and 2 fair evaluations;the range of motion of the wrist, Mayo score, grip strength, intrascaphoid angle and scapholunate angle were significantly improved. Conclusions Chronic scaphoid nonunion can be well treated with vascularized bone graft based on 1, 2 intercompartmental supraretinacular artery. A simple arthrolysis during the procedure can produce satisfactory results. External fixation plays a critical role in early mobilization and functional restoration of the wrist.

Objective To evaluate the medium and long term follow-up results of vascularized bone grafts dorsal distal radius in treatment of chronic scaphoid nonunion. Methods A retrospective study was carried out in 13 patients with chronic scaphoid nonunion treated with vascularized bone grafts dorsal distal radius in our hospital from 1995 to 2006. Nine patients were accompanied by avascular necrosis of the proximal pole. The vascular pedicle was 1,2 intercompartmental supraretinacular artery. The nonunion was stabilized by screws or external fixators. Radiographic finding and Mayo scoring system on wrist mobilization were used to evaluate the clinical outcomes. Results The interval between injury and treatment was average 22.2 months. All patients were followed up for average 76.6 months, which showed that 12 patients obtained fracture union, with average union time of 11.2 weeks. Functional evaluation results were defined as excellent in three patients, good in eight and fair in two. The last follow-up revealed significant improvement of the range of motion of the wrist, Mayo scores, grip strength, intrascaphoid angles and scapholunate angles. Conclusions Vascularized bone grafts from dorsal distal radius has relatively surgical procedure and can achieve satisfactory results in management of scaphoid nonunion. The perioperative arthrolysis and early postoperative mobilization of the wrist under exernal fixation play critical role in restoration of wrist function.
