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 .

Objective To investigate the effect of acupuncture combined with rehabilitation on Joubert syndrome. Methods 2 infants with Joubert syndrome were reviewed. Results After the treatment of acupuncture combined with rehabilitation for 4~6 months, the clinical symptoms of these 2 cases improved, and the scores of Gross Motor Function Measure increased. Conclusion Acupuncture combined with rehabilitation is effective on Joubert syndrome.

Objective To explore the effects of curdione on cognitive function and expression of inflammatory factors in the hippocampus after partial hepatectomy in aged mice.Methods The animals were divided into control group, sham group, operation group, and high-, medium-and low-dose curdione groups.The model of partial hepatectomy in aged mice was established according to the method reported in literature.The levels of SOD, MDA, CAT and GSH-Px in the hippocampus were detected by enzyme-linked immunosorbent assay (ELISA), while the expressions of NF-κB, IL-1β, IL-6 and TNF-α were measured by Western blot.Results The escape latency was significantly increased (P<0.01), and the number of platform-site crossovers was significantly decreased in operation group (P<0.05).Compared with those in operation group, curdione significantly decreased escape latency and increased platform-site crossovers (P<0.05, P<0.05).The levels of SOD, CAT and GSH-Px in the hippocampus were significantly decreased (P<0.05) and the content of MDA was significantly increased after partial hepatectomy (P<0.01), and these were reversed by curdione (P<0.05, P<0.05, respectively).The expressions of NF-κB, IL-1β, IL-6 and TNF-α protein were significantly inhibited by curdione (P<0.05).Conclusion Curdione can significantly improve cognitive dysfunction after partial hepatectomy in aged mice and the mechanism may be related to its inhibition of oxidative stress, inhibition of NF-κB activation and reduction of inflammatory cytokines IL-1β, IL-6 and TNF-α in the hippocampus.

Objective: To investigate the effect of Na+, K+ -ATPase on the increase of cytosolic Ca2+ level induced by hypoxia in rat cortical neurons. Methods: Using confocal laser scanning microscope and video based motion edge detection system, we measured the intracellular Ca2+ concentration ([Ca2+]i) and Na+ concentration ([Na+]i) in cortical neurons exposed to hypoxia for different time periods and at presence of different concentrations of dihydroouabain (DHO, an inhibitor of Na+, K+-ATPase). We also observed the effect of Na+, K+-ATPase on the increase of cytosolic Ca2+ level induced by hypoxia in rat cortical neurons. Results: DHO (10-9-10-3 mol/L) dose-dependently and hypoxia(4-20 min) time-dependently increased the levels of [Ca2+]i and [Na+]i in cultured cortical neurons. [Ca2+]i and [Na+]i increased significantly 4 min after cortical neurons were exposed to hypoxia, and addition of DHO (10-3 mol/L) further increased their concentrations. While 15 min after hypoxia exposure, different concentrations of DHO did not further increase [Ca2]i and [Na+]i. We also found that hypoxia exposure did not enhance DHO pretreatment-induced [Ca2+]i increase. Conclusion: Inhibition of Na+, K+ -ATPase activity is one of the mechanisms responsible for hypoxia-induced elevation of [Ca2+]i in cortical neurons.

This paper discussed the performance and cerebral localization of tone error occurred in patients with aphasia. The definition and characteristics of tone and aphasia were introduced briefly, while focusing on the brain lateralization of the tone. Tone is a language signal, but also has characteristics of melodic acoustic. The dual nature affects the cognitive process of tone languages. Therefore studies at home and abroad about tone showed that the conclusion of advantage of lateralization was inconsistent. In this paper, by summarizing the advantage of lateralization of listening perception with different languages, and generalizing the brain damage localization in aphasia patients with voice disorders, the dominant side of the tone in the brain was discussed. This paper also summarized and discussed the characteristics of voice disorder in aphasia.

The patient has found his neck mass for more than 30 years, and the neck mass has slowly growed into giant tumor. Five days ago, the neck giant mass suddenly burst, hemorrhage and overflow liquid. The giant mass with irregular in shape, surface uneven, skin highly tension and superficial venous engorgement, was seen in left lateral neck. CT scan demonstrates a mixture of solid, cystic and lobulated mass shadow within subcutaneous fat spaces of left lateral neck. Postoperative pathological examination proved that it is salivary gland pleomorphic adenoma.

Objective: To establish a determination for tetrahydropalmatine in Anzhong Pill.Methods: TLC scanning was used.Results: The average recovery was 97.24% and RSD was.3.1%.Conclusion: The method can be used for quality control of Anzhong Pill.

With the development of the market economy and the reform of the medical industry deepening and hospitals gaining the status of autonomy in China, the issue of hospital development strategy has come up. It is imperative to possess strategic analysis methods when formulating hospital development strategy. The authors introduce the analysis methods in strategic management into the field of hospital development management, proposing 3 modes of hospital development strategy analysis, viz. medical resources guided strategic analysis, competitive strategy analysis and knowledge progress based strategic analysis. At the same time, they argue for strategic integration and discuss several strategic problems hospitals in China are generally confronted with at present.

The demand for knowledge of productive health and the current status of productive health services provided by relevant governmental institutions were qualitatively and quantitatively studied. The study identified the key factors that influenced the demand for the productive health services and results of the services. It also discussed the effective approaches to control, planning and sustainable development of the reproductive health services for the floating populations.
