OBJECTIVETo compare the clinical effect of the double eyelid blepharoplasty with central minimal incision and with three minimal incisions. Methods: From Jul. 2010 to May 2012, 268 cases (Group A) received double eyelid blepharoplasty with central minimal incision, while 102 cases (Group B) underwent double eyelid blepharoplasty with three minimal incisions. Photos were taken immediately, and 1,2, 4, 8,12 weeks after operation. Operation time, recovery time and postoperative complications were evaluated and recorded. The operation time and recovery time were analyzed by Wilcoxon rank sum test. The postoperative complications were analyzed by chi square test. The satisfactory degree was analyzed by t test.
RESULTSThe operation time in Group A was (25.63 ± 3.74) min, compared with that (29.90 ± 4.13) min in Group B (Z = -8.011, P <0.01). Meanwhile, the recovery time in Group A was shorter than that in Group B (Z = -15.887, P <0.01). The occurrence rate of postoperative complications,including hematoma,recurrence and scar hyperplasia in Group A was also lower than that in Group B. At the same time, the satisfactory degree in Group A was(97.302 ± 1.764), which was higher than that(88.628 10.880) in Group B (t = 12.650, P <0.05).
CONCLUSIONSThe double eyelid blepharoplasty with central minimal incision, which is suitable for all cases except those who has serious blepharochalsais, has more advantages than double eyelid blepharoplasty with three minimal incisions.

Objective:
This study was designed to evaluate the clinical value of seven combinedtumor-associated autoantibodies (7-TAAB) in the diagnosis of non-small cell lung cancer (NSCLC).
Methods:
This is a cross-sectional study. The 81 newly diagnosed patients with NSCLC were enrolled. 46 patients with benign pulmonary diseases (BLD) and 55 healthy subjects were selected as the BLD group and the healthy control (HC) group, respectively. ELISA was used to detect the concentration of seven TAABs of p53, PGP9.5, SOX2, GAGE7, GBU4-5, MAGE A1 and CAGE in the serum of the NSCLC and the other two groups. The levels of lung cancer tumor markers CEA, NSE, SCC and CYFRA21-1 in serum were also detected in all enrolled subjects. Kruskal-wallis test was used for comparison among the three groups, Mann-Whitney test was used to evaluate the differences between the two groups, and positivity rates were analyzed by using standard χ2 tests and Fisher exact tests. The receiver operating characteristic (ROC) analyses were performed to evaluate the diagnostic efficacy of 7-TAAB or combination of 7-TAAB and traditional tumor markers.
Results:
The serological levels of six TAABs (p53, SOX2, GAGE7, GBU4-5, MAGE A1, and CAGE) in the NSCLC group were higher than that in the BLD group (p53:

Objective:
To establish a high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) method for the detection of serum oleic acid (OA), and preliminarily evaluate the role of OA in insulin resistance (IR) of type 2 diabetes (T2DM).
Methods:
OA-[ 13 C 5 ] was used as isotope-labeled internal standard, and the ion pairs of OA and OA-[ 13 C 5 ] were 281.3/281.3 and 286.3/286.3, respectively. The ultrapure water was used as mobile phase A and methanol: acetonitrile (1∶1, v/v) as mobile phase B in a ZORBAX SB-Aq C18 reversed phase column. Meanwhile, the gradient elution system with a flow rate of 0.3 mL/min was used. According to the CLSI guidelines (EP15-A3), the reliability of the established method was evaluated by detecting the performance indicators such as precision, trueness, linear range, stability and carrying contamination rate. Serum OA levels were detected by the established HPLC-MS/MS method in 109 patients with clinically diagnosed T2DM and 100 healthy controls. The insulin resistance index (HOMA-IR) was calculated to evaluate IR, and the relationship between OA and IR was further analyzed.
Results:
The established HPLC-MS/MS method for the detection of serum OA had good specificity and linearity in the range of 10-1 000 μmol/L (y=0.007 55x+0.004 83,r=0.997 7), and the low limit of quantification (LLOQ) was 10 μmol/L. It also had good precision, and the within-run coefficient of variation (CV) and total CV were not more than 1.62% and 1.73%, respectively, indicating that the method was suitable for the detection of serum OA. The serum OA levels in T2DM patients [(425.58 ± 220.17) μmol/L] were significantly higher than that in the healthy controls [(113.20±58.00) μmol/L], and serum OA levels were significantly correlated with HOMA-IR in T2DM patients and healthy controls. The area under the receiver operating characteristic (ROC) curve (AUC) of OA for the diagnosis of IR was 0.689. When the cut-off value identified by Youden index was 235.8 μmol/L, the sensitivity and specificity were 70.4% and 63%, respectively. When OA combined with fasting blood glucose (FBG) to diagnose IR, the AUC increased to 0.806, which was significantly higher than that of OA (P<0.05).
Conclusion
A scientific and efficient HPLC-MS/MS method for the quantitative detection of serum OA is established successfully, which provides a reliable method for the dynamic monitoring of the changes of OA levels in the patients with metabolic diseases.
