Objective To study warfarin and aspirin for ischemic stroke prevention in elderly patients with atrial fibrillation.Methods Fifty-three elderly patients with atrial fibrillation from January 2007 to December 2009 were enrolled in this study.All patients were divided into two groups by random digits table method:warfarin group treated with warfarin and aspirin group treated with aspirin.Incidence rate of ischemic stroke,side effect and cost-effectiveness were compared between two groups.Results Forty-nine patients were followed up,the dropout rate was 7.5％(4/53),28 patients in warfarin group,21 patients in aspirin group.Incidence rate of ischemic stroke in warfarin and aspirin group was 3.6％(1/28) and 28.6％(6/21),and there was significant difference (x2 =4.28,P ＜0.05).No significant difference was observed for side effect between two groups (x2 =0.07,P ＞ 0.05).For cost-effectiveness analysis,the ratio of cost-effectiveness was 16.3 yuan and 10.4 yuan in warfarin and aspirin group respectively,and there was significant difference (P ＜ 0.05).Conclusion Warfarin is more effective for ischemic stroke prevention in elderly patients with atrial fibrillation,but costs more than aspirin.

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.

BACKGROUND: Thawed allografts are usually discarded for various reasons. Whether these discarded allografts can be refrozen for later use and their histological changes in vivo have not been reported. OBJECTIVE: To investigate the histological characteristics of anterior cruciate ligament (ACL) reconstructed with the repetitive freeze-thawing allogenic Achilles tendon in New Zealand white rabbits. METHODS: Allogenic Achilles tendons were harvested from adult male New Zealand white rabbits, and were stored at -8 ℃ and thawed at 20 ℃ for 1, 2, 3 and 10 times, respectively, after sealed package and 60Co irradiation. Twenty-four adult male New Zealand white rabbits were enrolled: the left and right knees of 12 rabbits were respectively reconstructed with 1 (control group) and 2 times of freeze-thawing allogenic Achilles tendon, and another 12 rabbits underwent reconstruction with 3 and 10 times of freeze-thawing allogenic Achilles tendon, respectively. Three specimens from each group were evaluated with modified histology grading scores at 6, 12 and 24 weeks to assess the cell morphology, cell quantity, matrix staining intensity, fibrocartilage formation, new bone formation, tendon healing and cartilage injury. RESULTS AND CONCLUSION: The cell morphology, matrix staining intensity and total scores of the 10 times group were significantly higher than those of the other groups at 6 weeks (P < 0.05), but other parameters showed no significant differences among groups (P > 0.05). ACL reconstructed with 10 times of repetitive freeze-thawing allogenic Achilles tendons had higher histological scores at 6 weeks after modeling, but no significant differences were shown at 12 and 24 weeks after modeling. To conclude, our study only testifies better histological scores on the multiple times of freezethawing Achilles tendon than the less times of freeze-thawing Achilles tendon at the early period after operation.

Objective To discuss the effect of community nursing intervention on medication compliance and control rates of blood pressure in patients with essential hypertension.Methods Community nursing intervention was conducted to 73 community patients with essential hypertension. The patients' medication compliance was compared before and after intervention and their control of blood pressure was also observed. Results The difference was statistically significant in the comparison of patients' knowledge of antihypertension and the proper use of antihypertensive drugs before and after intervention. Blood pressure control rate was 80.82%.Conclusions Community nursing intervention can improve patients' medication compliance and effectively control the blood pressure of the patients.

Objective To investigate effect of Xiaoyao pill on superoxide dismutase (SOD), malondialdehyde (MDA), interleukin family and clinical efficacy in patients with pelvic inflammation.Methods 75 cases with pelvic inflammation were selected and divided into experimental group and control group randomly according to random number table method.37 cases in control group were treated with conventional anti-inflammatory and Qianjin pill, 38 cases in experimental group were treated with conventional anti-inflammatory and Xiaoyao pill, 14 days for a course.SOD, MDA and interleukin family were compared and the effective rate and adverse reaction rate were compared.Results Compared with control group post-treatment, SOD in serum in experimental group was higher(P<0.05),MDA in serum was lower(P<0.05);IL-1 and IL-8 were lower(P<0.05);IL-4 and IL-10 were higher(P<0.05).The total efficiency of experimental group was significantly higher than that of control group, the adverse reactions were lower (P<0.05).Conclusion Xiaoyao pill has good curative effect on the patients with pelvic inflammatory disease,the mechanism may be related to the elevation of serum SOD,IL-4, IL-10 levels and reduce the levels of MDA,IL-1,IL-8.
