The optimal distance from tumor to incision varied according to the cellular type of the tumor. In each case the cutting edge of the excised tissue was checked with frozen sections for cancer cells. Multiple neighboring skin flaps in full thickness raised from the periosteum were used to cover the large defects (the smallest defect is 25 20mm, the largest one is 75 65mm). The results showed that good cosmetic results were obtained in all cases, visual function was preserved in 35 of the 36 patients, and no recurrence of the tumor was found in 5 years' follow-up. One patient with squamous cell carcinoma that disseminated to nasal cavity and sinuses had a complication of meningitis after the operation,and it was cured with proper treatment.

Objective To analyze therapeutic effects of different methods of treating tibial plateau fractures. Methods The curative effects of the 35 operative cases and 32 non operative cases were evaluated according to the score scale of knee injures. The data were analyzed statistically. Results The excellent and good rate of functional restoration was 91.4% in the operative group and 62.5% in the non operative group (P

Objective To investigate the effects of health education on enhancing the compliance behavior of patients with diabetes mellitus (DM). Methods 63 DM patients were provided with systemic health education during their staying in the hospital. A follow-up interview was performed at the 6th month of discharge to gather the information of how importance of compliance behavior on the prognosis of DM. Result After the systemic health education, the patients could take medicine on time and had a good behavior in daily life, which will effectively improved their quality in the future life.Conclusion Systemic the health education can improve the compliance behavior of patients, and thus directly affects the prognosis of DM.

Objective To investigate the change of cognitive function in the elders with first acute ischemic brain stroke.Methods The cognitive function was determined using senile cognitive function(SECF) scale in 110 senile patients with first ischemic brain stroke and 60 healthy elders.According to different sites of cerebral infarction identified by CT imaging,their cognitive functions were compared,respectively.Results The cognitive function obviously decayed in the elders after the first acute ischemic stroke and had the relation with age and site of the infarction.Conclusion The elders with first ischemic stroke have obvious disorder of cognitive function and could directly influence the recoveries of the patients.So,the therapy should include both somatic and cognitive function treatment.

The endothelium of 20 cases of rabbit cornea including the normal and postoperated ones (2 weeks and I, 2, 3 months after penetrating keratoplasty) were observed by scanning electron microscope. The photographs of the endothelium in graft-host junction were analysed by computer-assisted image analysis system and the morphometric indexes are as follows: area of the cells, perimeters, density, figure coefficient, long axis, coefficient of variation of the area, and others. After operation the morphology and the density of the endothelial cells were different from the normal ones obviously, but the cells changed from enlargement and irregularity to normal progressively. At the time when the corneas were operated for 3 months, some differences still existed.

Objective:Through the analysis of the influence indicators of average hospitalization and comparison of differences of these indicators among different clinical departments in a hospital, to evaluate the medical quality and management level of the hospital and provide scientific reference for improving the hospital management efficiency and benefits.Methods:Gender, age and the type of medical insurance were analyzed using the chi square test. The length of hospital stay through 2009 to 2013 were analyzed using F test for patients of different insurance type and using t test for patients from different departments. All tests were completed using SPSS18.0.Results: The average hospital stay was decreasing year by year. Compared with the overall average length of stay, the patients who pay free were stay longer in hospital except for a small number of departments of internal medicine. Besides, the severe cases also prolonged the average length of stay in hospital.Conclusion: To effectively control the average length of stay, the Physicians Examination in Three Levels should be strictly implemented and the information management system should be used scientifically. Reasonable measures should be taken to solve the existing problems.

Objective To identify the value of multiparametric MR imaging features including diffusion weighted (DW) and dynamic contrast-enhanced (DCE) MR imaging features in differentiation between inverted papilloma and malignant transformation of inverted papilloma in the sinonasal region.Methods Seventy-seven patients were included in this study,including 12 malignant transformation of inverted papilloma and 65 inverted papillomas.Conventional MRI including nonenhanced and static contrast-enhanced imaging,DCE-and the DW-MRI were analyzed.Differences in conventional MRI features,ADCs and DCE-MRI parameters between the two entities were determined by Fisher exact test,independent samples t-test and Mann-Whitney U test,respectively.Results There were significant differences in convoluted cerebriform pattern (P=0.045),necrosis (P=0.003) and orbit involvement (P＜ 0.01) between inverted papilloma and malignant transformation of inverted papilloma in the sinonasal region.The ADCs of inverted papilloma were significantly lower than those of malignant transformation of inverted papilloma (P＜0.01).There were significant differences in time to peak enhancement (P＜0.01),maximum contrast index (P=0.004) and time intensity curve types (P＜0.01) between the two entities.Conclusions A multiparametric approach using conventional MR imaging with added ADCs and DCE-MRI parameters had the potential to improve the differentiation between inverted papilloma and malignant transformation of inverted papilloma in the sinonasal region.

AIM: To investigate the apoptosis of endothelial cells (EC) induced by oxysterols and to examine the effect of amlodipine on the apoptosis induced by oxysterols.METHODS: Light microscope, electron microscope, DNA agarose gel electrophoresis and flow cytometry were used to detect the apoptosis of EC.RESULTS: The characteristic morphological features of apoptosis were observed under light and electron microscope; DNA electrophoresis showed"DNA Ladder"; Flow cytometry showed the sub-G1 peak, apoptotic rate is 32.25% and 23.04% in Triol-treated and 25-OH-treated groups, respectively. While treated EC with amlodipine at the same time, the apoptotic rate decreased significantly. CONCLUSION: Both Triol and 25-OH can induce apoptosis of EC, which can be inhibited by amlodipine.

AIM: To investigate the effects of oxysterols on matrix metalloproteinase (MMP) and tissue inhibitor of metalloproteinase-1 (TIMP-1) expression in vascular smooth muscle cells. METHODS: Rabbit aortic vascular smooth muscle cells were cultured in vitro and incubated with cholesterol, Triol and 25-hydroxycholesterol (25-OH), respectively. Slot blot was used to detect the mRNA expression level of TIMP-1 in vascular smooth muscle cells (VSMCs); meanwhile the protein expression level of MMP-9 and TIMP-1 was detected by immunohistology. RESULTS: Triol and 25-OH inhibited the expression of TIMP-1 compared with control and cholesterol, but have no effect on expression of MMP-9. CONCLUSION: Both Triol and 25-OH downregulated TIMP-1 expression in VSMCs .

Objective To explore the role of a new apoptosis related gene TFAR 19 in the pathogenesis of systemic lupus erythematosus (SLE) and the relationship between TFAR 19 and SLE.Methods ELISA was used to test if there is relation between TFAR 19 and SLE.Results It was found that in active SLE patients there was higher titer of TFAR 19 antibody than that in stability patients and normal controls.No significant difference was seen between stability patients and normal controls.Conclusion It is first put forward that TFAR 19 may be related with SLE pathogenesis and disease activity.
