Objective To investigate the etiology and clinical features of transient global amnesia.Methods Seven patients diagnosed as transient global amnesia were analyzed by EEG,TCD,MRI or CT examination,five pa- tients analyzed by single photon emission computed tomography(SPECT).EEG and TCD examination were done within 24 hours during the attack.And SPECT,MRI or CT examination were done within 1 week during the at- tack.Results Six patients showed normal EEG,one patient showed a few slow waves;seven patients showed verte- brobasilar ischemia in TCD;six patients showed normal but one patient showed lacunar infarction in brain CT or MRI;five patients showed significant hypoperfusion in different encephalic region in brain SPECT.They were all fol- lowed up for three to tewty-four months respectively,six patients had no recurrence,but one patient recurred one time and the SPECT demonstrated a decreased cerebral blood flow in the left temporal lobe.Conclusion Transient global amnesia patients showed cerebral ischemia.Transient global amnesia may be related to the decrease of rCBF in the temporal lobe or the temporal hippocampus.

Objective To observe the expression and role of HSP70 in human epidermis and cutaneous neoplasms.Methods 56 cases of epidermis tumors,including 29 biopsy samples from basal cell carcinoma, 27 from squamous cell carcinoma,and 30 from normal human skin were investigated. HSP70 expression was examined by immunohistochemical SABC staining with specific monoclonal antibodies.Results The expression of HSP70 was detectable in the cytoplasm throughout the epidermal cell layers in normal human epidermis,HSP70 expression in the tumor cells in basal and squamous cell carcinomas was reduced (P

ObjectiveTo study specific allergic IgG antibody test and its impact factors.MethodsA total of 1770 Qingdao residents were recruited in this cross-sectional study from January to October 2011.ELISA was used to test specific allergic IgG antibodies.Logistic regression was used for multifactor analysis.Results Of 1770 participants,9 individuals had insufficient data,resulting in a response rate of 99.5％.Identification rate of specific allergic IgG antibody was 60.0％ (1056/1761 ),and the most commonly seen allergic foods were crab (49.4％ ),egg (44.80％ ),ling (38.0％ ),shrimp ( 30.4％ ) and soy ( 22.2％ ).Intolerance to crab,egg,shrimp,creamery,com,and tomato showed gender difference ( x2 =18.978,P＜0.05 ).Serum level of allergic IgG antibody was increased with age [20 - 40 years:( 118.61 ±45.67) U/ml; 41-60 years:(166.57 ±55.82) U/ml; ＞60 years:(183.67 ±49.34) U/ml; x2=13.597,P＜0.01].In logistic regression,difference between individuals with normal body weight and obesity population ( OR =1.897,95％ CI 1.215 - 2.578 ) or between those with or without allergic history ( OR =0.780,95％ CI 0.648 - 0.912) was found.Conclusions Impact factor of food intolerance includes gender,age,constitution and body mass index.Six kinds of food intolerance are more common in women.41 -60 year group shows peak of food intolerance.No exposure to allergic food and antianaphylaxis may reduce the risk of food intolerance.

This article is to explore the practical application of concept maps in nursing teaching practice to make it as a learning tool to promote undergraduates to make a meaningful study. Besides, the results is applied in research on improving the teaching method so as to provide an effective teaching policy and evaluation tools to promote the scientific research and clinical practice in nursing care.

Objective Peritoneal dialysis can be done at home , however , its clinical follow-up quality is lower compared with hemodialysis due to the lack of detailed follow-up system and professional management team for post-discharge nursing care .The article aimed to explore the effect of a nurse-led integrated specialized disease management model in the follow-up of peritoneal dialysis patients . Methods Nurse-led integrated specialized disease management model was provided for 270 patients with peritoneal dialysis (PD) from January 2012 to May 2013.Self-designed questionnaire on diasease knowledge and self-care assement questionnaire were used for patients to evaluate their self-care ability and understanding of disease knowledge .Regular follow-up continued . Results The patients′understanding of disease knowledge was on the rise at 1st day before discharge, 1st month and 3rd months after discharge. After the application of nurse-led integrated specialized disease management model , the patients′regular clinical follow-up rate was in-creased from 78.3% to 88.6%.The patients′self-care ability improved gradually at 1st day before discharge , 1st month and 3rd months after discharge , which was of significant differences . Conclusion The nurse-led nurse-led integrated specialized disease management model can improve peritoneal dialysis patients′self-care ability and reduce their medical expense , which is of clinical sig-nificance .

Objective To investigate the diagnostic value of breast MRI in patients presenting with microcalcifications on mammography.Methods Eight four patients were retrospectively analyzed,who had mammographically detected BI-RADS (breast imaging reporting and data system) 3 to 5 microcalcifications and underwent breast MRI before surgical biopsy.All mammography and MR images were reviewed with BI-RADS.With histopathological diagnosis as golden standard,the sensitivity,specificity and accuracy of the two methods were calculated and compared with x2 test or Fisher exact test.The diagnostic efficacy of the two methods was compared with ROC curve.Results Pathologic examination revealed 91 lesions in 84 patients including 49 benign lesions and 42 malignant lesions.For 21 lesions of category 3 microcalcifications,the specificity of mammography and MR was 100.0％ (21/21) and 95.2％ (20/21),which had no significant difference (P=1.000).For 51 lesious of category 4,sensitivity,specificity and accuracy of mammography were 100.0％(23/23),0 and 45.1％(23/51).The corresponding values for MR were 91.3％(21/23),82.1％ (23/28) and 86.3％ (44/51).The difference for specificity and accuracy between the two methods was statistical significant(x2 value was 30.030 and 19.182,respectively,with P＜0.01),but not for sensitivity(x2=0.523,P=0.470).Nineteen lesions of category 5 were all correctly diagnosed on mammography and MRI.For all the 91 lesions,the sensitivity,specificity and accuracy of mammography were 100.0％(42/42),42.9％(21/49) and 69.2％(63/91),respectively.The corresponding values for MRI were 95.2 ％(40/42),87.8％(43/49) and 91.2％(83/91).There was significant difference for specificity and accuracy between the two methods (x2 value was 21.798 and 13.851,respectively,with P＜0.05),but not for sensitivity (x2=0.512,P=0.474).The areas under ROC curve for mammography and MR were 0.844,0.945(P＜0.01),for the estimation of the benign and the malignent.Conclusions Compared with mammography,breast MRI significantly improved the diagnosis of category 4 microcalcifications with increased specificity and accuracy.But for microcalcifications of category 3 and 5,MR didn't improve the diagnostic effect.

Objective To investigate the surgical treatment and prognosis of bronchial mucoepidermoid cancer. Methods During a 17-year-period, 19 consecutive patients underwent surgery for bronchial mucoepidermoid cancer, and the surgical treatment and prognosis were analyzed retrospectively. Results Among them, 13 cases were treated by lobectomy, 5 by pneumonectomy, and 1 by exploratory thoracotomy. Four cases were proved pathologically to be high malignancy and 15 low malignancy. All patients were followed up postoperatively for about 68.26 months on average. The 1, 3, and 5-year survival rates were 94.44%, 80.00%, and 70.00% respectively. In the low malignancy group, the 1, 3, 5-year survival rates were 100%; in the high malignancy group, the 1-year survival rate was 33.33%, and 3-year survival rate was 0. Conclusion Patients with low malignant grade of cancers can be cured after complete resection, and those with high malignant grade predispose to metastasis and hence result in a poor prognosis.
