Objective:To compare the efficacy and complication in clinical application about the indwelling central venous transfusion port and peripheral venipuncture central vein indwelling catheter.Methods: 80 cases with indwelling central vein transfusion port were arranged to observation group and 80 cases with peripheral venipuncture central vein indwelling catheter were arranged to control group. All of patients were detected for blood routine, blood coagulation time and chest X-ray fluoroscopy routine examination before operation. And to take venipuncture by right subclavicle of patient skin under X-ray fluoroscopy guided, and then indwell catheter. To compare the clinical effect for the two kinds of indwelling catheter method.Results:In observation group, the successful rate was 97.5% (78/80), the average operation time was (51.23±10.21) min; while in control, the successful rate was 78.8% (63/80), the average operation time was (67.42±11.03)min, there were statistical significant difference in successful rate (x2=13.44,P<0.05) and average operation time (t=9.63,P<0.05) between observation and control group. In observation group, the rate of complications occurred was 13.75% (11/80), which was significant lower than 32.5% of control (26/80)(x2=7.91,P<0.05).Conclusion: It is safe and reliable to use the dwelling central venous transfusion port, and the complication of some patients mainly related with nursing skill of paramedic and the proficiency degree of pillbox puncture and using skill in this operation.

BACKGROUND:Laryngeal cartilage defect has a higher incidence, mainly presenting with pain, sweling, and dysfunction after onset. Currently, surgical treatment is the most used in clinical treatment of laryngeal cartilage defect. Although conventional materials can effectively improve symptoms, there is a poor long-term efficacy. In recent years, there are many clinical studies on cartilage tissue engineering, but less about the actual use in the otorhinolaryngology department.
OBJECTIVE:To investigate the effect of polyhydroxyalkanoate polymer carrying chondrocytes on the repair of alogeneic laryngeal cartilage defects.
METHODS:Poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBHH) served as the extracelular matrix. Tissue engineering technology was used to prepare cel-material composite. Primary tissue-engineered cartilage tissue was transplanted directly into rabbit thyroid cartilage defect (experimental group A), or implanted into a more mature tissue-engineered cartilage for the repair of thyroid cartilage defect (experimental group B). In the experiment, PHBHH group and simple chondrocyte group were set as controls. Repairing effects on thyroid cartilage defect were evaluated through gross and histological observation.
RESULTS AND CONCLUSION:Chondrocytes in the primary tissue-engineered cartilage tissues were beaded under scanning electron microscope, and after 4 weeks of culture, a large amount of jely-shaped substrates were visible. Findings from electron microscope observation showed that the cels were distributed on the surface of composite material and cavernous voids, displaying a plurality of smal round projections. Surgical treatment was successful in al the rabbits, and there was no dyspnea and eating difficulties after surgery. One rabbit appeared to have brief wheezing in the experimental group A, two rabbits died of diarrhea in the experimental B group at 2 weeks after surgery. PHBHH composite carrying chondrocytes had certain hardness. At 4 weeks after subcutaneous implantation, mature cels were shaped as white sheets, and the material had elasticity. After 4 and 8 weeks, the space between repair zone and original cartilage tissue was smooth and plain, but the repair zone was colored yelow. In the simple PHBHH and chondrocyte groups, the repair zones were both depressed, only the connective tissues could be seen. Rabbits in the two experimental groups showed less adverse reactions compared with the two control groups (P < 0.05). These findings indicate that PHBHH composite carrying chondrocytes has better effects to repair alogeneic laryngeal cartilage defects.

Objective To analyze the clinical characteristics and prognostic factors of endometrial carcinoma in senile women, explore the optimized therapeutic modality. Method The clinic pathological characteristics and survival outcome of 268 patients of endometrial carcinoma in senile women were reviewed retrospectively, and prognostic factors affected the survival of endometrial carcinoma were evaluated. Results According to univariate analysis, therapeutic modality, surgical-pathological classification and pathological grade were closely correlated with prognosis of endometrial carcinoma in senile women(P < 0.01 ). According to COX multivariate analysis,surgical-pathological and pathological grade were independent prognostic associated-factor (P = 0.002,0.000). Conclusions There are closely correlations between prognosis and surgical-pathological classification,therapeutic modality and pathological grade,surgical-pathological classification and pathological grade are independent prognostic associated-factor. The therapy on endometrial carcinoma in senile women should connect with high risk factors and adopt integrating and individual therapeutic modality.

In order to adapt to the changes in the training model of medical professionals and meet the new re-quirements of information literary recommended by ACRL, medical information literacy education was reformed with the5+3+Xtraining model of clinicians proposed by Capital Medical University as an example, namely strengthening meta-literacy training by establishing new framework of medical information literacy education, implementing open education with new teaching methods, building assistant teaching platform, increasing class hours,etc.

The analysis of 2013 circulating foreign and Chinese books in Library of Capital Medical University showed that the number of foreign and Chinese books classified into R Medicine and Healthand I Literaturewas the largest ,which thus provided the evidence for book acquisition ,book circulation and library holding develop-ment.Certain suggestions were put forward for improving the utilization of books, such as enforcing the acquisition and catalogue , and recommending books that should be bought .

The review summarized the diagnostic strategy of ischemic cerebrovascular diseases and introduced some progress in clinic.As ischemic cerebrovascular diseases were highly heterogeneous,the review analyzed their characteristics step by step.Through the primary diagnosis,etiological diagnosis,evaluation of risk factors and factor analysis of the whole body,the review describe the diagnostic program of the diseases and provide suggestion about the individually therapy and prevention.

The use and management of medical implanting material is always the key point of the hospital material management. Questions existing in hospital management were investigated along with some suggestions in further management in the system and the process.

AIM: To study the antitumor e ff ects of losartan in EAC mice. METHODS: The inhibitory rates of t umor growth and the ratio of extending viability were observed in EAC mice in th ree groups given losartan, 5-FU and NS, respectively. RESULTS: Comparing with the control groups, the inhibition to tumor growth was 46.3 % in losartan ( 12.5 mg?kg -1 ) group. But losartan did not lengthen life time in EAC mice. The inhibition to tumor growth was was 31.5 % in 5-F U (5 mg?kg -1 ) group. CONCLUSION: Losartan can inhibit the tumor growth of EAC, but not lengthen life time of the animals.
