Objective To treat scalp lacerations by using the hair apposition technique (HAT) and to compare the HAT with standard suturing in a controlled prospective trial. Method Fifty patients with scalp lacerations were treated either by HAT or by standard suturing. Two groups were evaluated in consumed times for operation, pain sores, and complications. Results There were 30 HAT patients and 20 patients treated with suturing. The took shorter operation time consumed[(3.33 vs. (6.05 t = 4.85.P < 0.01], and HAT produced significantly lower pain score [(1.73vs. (3.20t = 4.01,P < 0.01]. There was a trend that more and more patients were willing to have HAT performed. Conclusions The advantages of HAT include a shorter time consumed for operation, less pain, satisfactory wound healing, and high acceptance by patients. HAT is acceptable for treating scalp lacerations in emergency room.

[ABSTRACT]OBJECTIVETo study the expressions of 34βE12, Galectin-3 and HBME-1 in thyroid nodules, and to explore its diagnostic value for papillary thyroid carcinoma (PTC).METHODSEn VisionTM immunohistochemical technique was used to detect the expression of 34βE12, Galectin-3 and HBME-1 in 352 thyroid lesions. The correlation between the expressions of the 3 protein markers and clinicopathological characteristics was evaluated. The receiver operating characteristic area under the curve (ROC-AUC) and their index for diagnosis evaluation were also calculated.RESULTSThe positive rates of 34βE12, Galectin-3 and HBME-1 in 246 PTC lesions were significantly higher than those in benign nodules (P<0.001). There was no relationship between the expression of the 3 protein markers and clinicopathological characteristics (eg. gender, age, numbers of lesions, tumor size, capsular invasion, lymph node metastasis, TNM staging). The ROC-AUC of 34βE12, Galectin-3 and HBME-1 for diagnosis of PTC was 0.936, 0.915 and 0.898 respectively. The sensitivity of 34βE12, Galectin-3 and HBME-1 for diagnosis of PTC was 94.3%, 95.5% and 91.1% respectively, while the specificity was 81.1%, 71.7% and 83.0% respectively, and the diagnostic accuracy rate was 90.3%, 88.4% and 88.6% respectively.CONCLUSION The expressions of 34βE12, Galectin-3 and HBME-1 are statistically different between PTC and benign lesions, but no associations are found with clinicopathological characteristics, indicating the three protein markers have important diagnostic value for PTC.
