Objective To investigate a mechanism protected radiation-induce injure for radiated guinea pigs'nasal mucosa treated with intranasal corticosteroids (fluticasone nasal cavity spray). Methods 50 health guinea pigs were divided into 2 groups randomly: the irradiated group (control group) with 25 guinea pigs and the administration group after irradiation (test group)with 25 guinea pigs. The nasal part of all guinea pigs were performed irradiation by the 6 MV X-ray with single 5 Gy, one time each week for three weeks. The guinea pigs of test group received intranasai eorticosteroids with one time every day and one spray each side nasal cavity on the second day after three weeks irradiation. Five guinea pigs in each group were saeritieed randomly at 1 week, 1 month, 2 months, 3 months and 4 months after irradiation, and the histopathologie changes were observed under optical microscope and electron microscope. At the same time, blood were drawn from the heart and the concentration of IL-1, IL-6 and TNF-α in serum were measured by ELISA. Results The early nasal mucosa inllammatory reaction of the test group was less than the control group. The coverage rate of cilia of the test group was much than that of the control group (72.9% vs 50.2%) at four months after irradiation. The atrophy of submucosal glandular organ was lessened and they displayed some extent secretory function. The concentration of IL-1 in serum was increased very much in the test group compared with the control group after irradiation and kept higher level in the first two months. After two months, it began to decrease;on four months, it still kept equivalency level with the control group. The concentration of IL-6 and TNF-α in serum were reduced all the while. Conclusions The intranasal eortieosteroids with fluticasene nasal cavity spray can reduce radiation-induced injury of guinea pigs' nasal mucosa. The concentration change of IL-I, IL-6 and TNF-α in serum may be one of mechanism protected radiation-induce injure of guinea pigs' nasal mueosa.

Objective To study the influence of cilostazol to aspirin resistance in patients with coronary heart disease.Methods A total of 165 patients with coronary heart disease were set apart two groups:group A:coronary heart disease,group B:coronary heart disease by 2-diabetes mellitus,Both group A and group B received 100 mg of aspirin daily for 7 days and no other antiplatelet agent.The blood samples were analyzed by platelet aggregation(PAG)test.Platelet aggregation using adenosine diphosphate(ADP)and arachidonic acid(AA).then two groups were randomized four groups:A1,A2,B1,B2 separately.both group A1 and B1received aspirin 100 mg qd continuely,group A2 and B2 added anther antiplatelet drug cilostazol 50 mg bid,redetected platelet aggregation after a week.compared PAG and AR using statistic methods.Results PAG and AR of group A is lower than group B(P0.05).The PAG and AR of group A2 was significantly lower than group A and group A1(P0.05),the PAG and AR of group B2 is significantly lower than group B and group B1(P

Preoperative qualitative diagnoses of 118 eases of renal tumour.made by B-mode ultrasound were analyzed.The final diagnoses were proven operatively and pathologically.The resultsshowed that by B-mode altrasound the detective rate was 92.2%,a correct qualitative diagnosis rate 49.1%,incorrect rate 18.1%and false positive rate 1.7%.Qualitatively unidentified turnouts accounted for 32.8%of all the cases.It is assumed that B-mode ultrasound can be used to make correct qualitative diagnosis only on certain tumours with typical image features.It is difficult for it to distinguish some tumours which have complicated displays.The accuracy of preoperative qualitative diagnosis could be raised by combining B-mode uhradound with other imaging technologicol examinations.

Objective: To study shame of college student through phenomenological method. Method: 147 college students (male 53, female 94, average age 20.2) were involved. Each subject was asked to describe his/her personal shame experience, which was rate on phenomenological dimensions. Experience of Shame Scales (ESS) was used either. Result: The finding from phenomenological rating was in accord with the theory of “self orientation". Students with stronger shame proneness showed tendency to attribute negative events to him/herself. Conclusion: Shame is an acutely painful experience that involves a marked self-focus (self oriented) emotion. Shame proneness tended to have stronger sense of worthlessness and powerlessness and have much more strategies of denying and escaping in hard situations.

Objective To explore the clinical characteristics of primary central nervous system malignant lymphoma (PCNSML). Methods The clinical data of 22 cases of PCNSML were analyzed retrospectively.Results The patients in our study mainly presented with headache (16 cases), vomiting (11 cases), weakness of extremities (5 cases) and numbness (1 case). The tumors were supratentorial in 19cases, infratentorial in 3 cases and multiple in 5 cases. CT scan showed same density or high-density lesions with surrounding mild edema. Brain MRI demonstrated slight-hypointense lesion of 9 cases and isointense lesion of 5 cases on T1-weighted imaging. On the T2-weighted imaging, the lesions were slight-hyperintense in 11 cases and isointense in 3 cases. Enhanced scanning showed that the lesions were contrasted evenly and obviously on CT and MRI. Misdiagnosis was given preoperatively in 17 patients. The pathological examination revealed B cell malignant lymphoma in all cases. In 18 cases of follow-up, 5 patients with multiple lesions who only received stereotactic biopsy all died within 6 months, the mean survival time of 6 patients who were treated with total resection of the tumors and radiotherapy was 27 months, 4 patients treated with partial resection and ?-radiotherapy was 21 months, 4 patients treated with partial resection and radiotherapy was 10 months. The patient who was treated with only total resection of the tumor died in 11 months because of recurrent. Two patients with only partial resection died in 5 and 8 months, respectively.Conclusions There are no specific clinical manifestations of PCNSML and the disease is often misdiagnosed preoperatively. Although certain characteristic performance may be found on CT and MRI scans, the final diagnosis of this disease depends on pathological examination. Comprehensive treatments may prolong the survival time of the patients.

Objective To investigate the level of myocardical injury by measuring serum levels of cTnI, MYO, CK and CK-MB before and after catheter ablation in patients with atrial fibrillation. Methods Forty nine patients underwent catheter ablation for atrial fibrillation were involved in the study, cTnI, MYO, CK and CK-MB levels were measured before and 4 h after catheter ablation.
