Objective To evaluate the performance of an improved skin prick test in infantile eczema.Methods A self-controlled study was carried out in 248 infants with eczema.Improved and conventional skin prick tests were conducted with 8 allergens on the left and right flexural forearm of the subjects,respectively.Results Positive results of skin prick test were found in the left flexural forearm of 38.3％ of the infants,and in the right flexural forearm of 38.7％ of the infants,with no significant difference between the two methods in the detection rate of allergens (P ＞ 0.05).The most common sensitizing allergens were house dust mite and Dermatophagoides culinae as shown by both methods.Conclusions The improved skin prick test displays an acceptable performance with simple and safe procedure in the detection of allergens in infants with eczema,and can provide reliable evidence for clinical diagnosis.

Objective To assess the single-exponential and dual-exponential fitting methods of MR T2-Map, and to get T2 value of each pixel. Methods Single and dual-exponential methods with linear fitting and non-linear regression fitting techniques were used for a series images with different TE; then T2-Map images were achieved. T2-Map software was realized on MATLAB and it had the function of compute, display, save and so on. Results T2-Map software with single-exponential and dual-exponential fitting methods was achieved, able to calculate T2 value of tissues everywhere and form the T2-Map image. Conclusion Single-exponential T2-Map method is convenient, having obvious merit-high speed, but can not show the area with obvious different contents very well. However, dual-exponential fitting method can deal with this question with providing different T2 values, thus is accurate with the sacrifice of costing too much time. Dual-exponential fitting method of T2-Map is a beneficial supplement to single-exponential method.

Objective To assess the efficacy of a long-pulsed 1064 nm Nd :YAG laser system in treating pediatric cutaneous hemangiomas. Methods 207 patients (20 days-10 years old,164 cases in pro-liferative phase and 43 in stationary phase) with cutaneous hemangiomas were divided into 2 groups ac-cording lesions. Group A contained 142 patients with lesions located in skin completely. Group B con-tained 65 patients, in which the lesions involved in subcutaneous portion. All patients were treated with single pulse shots by a long-pulsed 1 064 nm Nd :YAG laser, with 2 mm and 6 mm spot size in diameter, and with related energies from 50 to 90 J/cm~2 and pulse lengths of 10, 40 and 60 ms, respectively. All treatments were given at 1-month interval. Results After 1-6 times of treatment, there was no statistic significance of effective rate between group A and group B. Both general effective rates were 100%. The rate of side effects was 11.6 %, all of which recovered gradually. Conclusions The long-pulsed 1064 nm Nd : YAG laser offers efficient treatment of pediatric superficial cutaneous hemangiomas and side effects are minimal and transient.

Background and purpose: The position of thymidine kinase 1 (TK1) expression during cell division is in the cytoplasm. It is a catalytic enzyme to convert deoxythymidine into thymidylate. It is the key enzyme of pyrimidine salvage pathway. The aim of this study was to analyze the serum expression level of TK1 in patients with breast cancer, and explore the application of serum TK1 test in clinical assessments of diagnosis, treatment and prognosis for breast cancer. Methods: Patient data were collected from the patients admitted in Comprehensive Breast Health Center at Rui Jin Hospital. Chemiluminesence dot blot assay was used to detect serum TK1 levels in 145 breast cancer patients and 55 patients with breast ifbroadenoma. The correlations of serum TK1 levels with breast tumor biological behavior was further studied. Results:Serum TK1 expression levels was signiifcantly increased in breast cancer patients [(2.749±0.122)pmol/L] when compared to breast fibroadenoma patients[(1.319±0.126)pmol/L, P<0.000 1]. Serum TK1 levels were statistically increased in patients with lymph node metastasis (P=0.049), distal metastasis (P=0.003 1), and late TNM stages (P=0.01). No serum TK1 level differences were found in patients with different ages (P>0.05), different tumor grades (P=0.453) and different tumor size (P=0.908). Preoperative imaging results including breast ultrasound, breast mammography and breast magnetic resonance were analyzed by assessments of BI-RADS category, and serum TK1 levels in patients with different BI-RADS categories were studied. Serum TK1 levels in patients with breast ultrasound BI-RADS categories 4C-6 were signiifcantly higher than those with category 0-4B (P<0.001). Consistently, the serum TK1 levels in patients with MR BI-RADS categories 4C-6 were higher than categories 0-4B (P=0.005). The serum TK1 levels in patients with mammography BI-RADS categories 4C-6 were higher than categories 0-4B (P=0.032). The serum TK1 levels were signiifcantly increased in patients with ER high expression in breast tumor tissues than those with low expression (P=0.034). Serum TK1 levels had no differences in patients with different expression levels of PR, HER-2 and MIB-1 (P>0.05). Most patients were followed up in our outpatient department for about 2 years. No progression-free survival differences were found in 2years. Conclusion:Serum TK1 test might be a potential tool for screening, prognosis determination and effect evaluations of targeted therapy in breast carcinoma.

Objective To evaluate the accuracy of ultrasonography and magnetic resonance imaging detection on preoperatively predicting axillary lymph node in breast cancer patients.Methods From August 2010 to February 2011,the clinical data of 293 breast cancer patients underwent preoperative breast ultrasound exam and MRI detection in Ruijin Hospital were analyzed retrospectively.Results In 293 breast cancer patients,3 suffered from bilateral breast cancer.The sensitivity,specificity,negative predictive value and positive predictive value of ultrasound were 60.0％,90.6％,78.0％ and 80.2％,respectively.The sensitivity,specificity,negative predictive value and positive predictive value of MRI test were 50.5％,90.8％,74.0％ and 77.9％,respectively.There was no significant difference between ultrasound and MRI test in these four indices (P ＞ 0.05).No significant difference on accuracy and predictive value was seen in subgroup analysis according to tumor size,tumor grade,hormone receptor and HER2 status between the two examinations.The sensitivity and specificity of ultrasound associated with MRI test were 70.6％ and 97.2％.Conclusions The accuracy and predictive value between preoperative ultrasound exam and MRI is comparable.Ultrasound associated with MRI examination can achieve high specificity,which may spare a portion of patients free from sentinel lymph nodes biopsy.

Objective To investigate the expression of activated ERK (p-ERK) and activated p38 (p-p38) in the keratinocytes of condyloma acuminata (CA) lesions. Methods Fifty cases of HPV 6/11 CA were diagnosed by in situ hybridization. The expression and distribution of p-ERK and p-p38 in CA lesions and 25 normal human skins (foreskins) were detected by immunohistochemistry technique (En Vision). Results ①The results showed that the expression of p-ERK and p-p38 in keratinocytes of CA lesions were significantly higher than those in normal epidermis (P

Objective To observe the influence on early blood glucose by 3 L fluid replacementafter kidney transplantation. Methods Patients(60 cases) after kidney transplantation were randomly di-vidod into two groups.Group A used circular fluid replacement and Group B used 3L fluid replacement. Thelevel of blood glucose was detected before operation,after operation ,once every 8 hours at the first day,thenonce a day for the following six days. Results The level of blood glucose with 3 L fluid replacement waslower than that with circular fluid replacement,especially from the fast day to the fourth day after operation(P < 0.05). Conclusions The method with 3 L fluid replacement surpasses obviously circular fluid re-placement in blood glucose control after kidney transplantation.

Objective To study clinical feature and therapeutic choice of pituitary adenomas. Methods The clinical data of 239 cases of pituitary adenomas were analyzed. Results Total 93 male and 146 female cases were recruited. The average age was (43.8 ± 14.9 ) years old (3.9-77 years). Prolactinomas were the most common pituitary adenomas (26.8%) , 179 patients (74.9%) underwent surgery, of which 108 (60.3%) with transsphenoidal approach and 71 (39.7%) transcranial approach. The other 60 cases were treated nonsurgically. Conclusions Pituitary adenomas may present hormonal abnormalities or neurological symptoms.Some adenomas were accidently detected by MRI. Prolactinomas were the most common pituitary adenomas.
