Objective: To understand the relationship between mental health status and vision-related quality of life( VRQL ) of students with moderate and high myopia, and to provide basis for the optimization of VRQL. Methods: Using convenient sampling method, the 8-18 years old students with moderate and high myopia were selected from Sichuan, Chongqing and Zhejiang. The mental health status and VRQL of students with moderate and high myopia were evaluated with Hospital Anxiety and Depression Scale and Quality of Life Scale for Ametropia. The multiple linear regression model was used to analyze the influencing factors for VRQL. Results: A total of 360 questionnaires were sent out and 354 were effectively recovered, with an effective rate of 98.33%. There were 116 ( 32.77% ) boys and 238 ( 67.23% ) girls; the median age was 16.65 years old. There were 211 ( 59.60% ) cases of moderate myopia and 143 (40.40%) cases of high myopia.There were 141 ( 39.83% ) found to be anxious and 176 ( 49.72% ) depressed. The median score of Quality of Life Scale for Ametropia was 64. The results of multiple linear regression analysis showed that sex ( β＇= -0.179 ), diopter ( β＇= 0.208 ), eyesight with glasses ( β＇= -0.229 ) and anxiety ( β＇= 0.439 ) were influencing factors for VRQL. Conclusion The mental health problems of the students with medium and high myopia are prominent; anxiety has a significant impact on the VRQL of the students.

CONCLUSION: Medpor lower eyelid inserts implantation can instead tarsal plate for the reconstruction of medium to large areas lower eyelid defect, which is easy performing with rare complications. It is an ideal alternatives of tarsal plate.

AIM To investigate the correlations between antioxidant activities and contents of total flavonoids and total phenols of chloroform,ethyl acetate,n-butanol and ethanol extracts from Nervilia fordii (Hance) Schltr..METHODS The contents of total flavonoids and total phenols in four extracts from N.fordii were determined by AlCl3-HAc-NaAc coloration method and Folin-Ciocalteu colorimetric method,respectively.The antioxidant activities of extracts were evaluated by determining scavenging activities of DPPH radical,hydroxyl radical and ABTS radical,together with reducing power.Then the correlations between antioxidant activities and contents of two constituents were analyzed by SPSS17.0 software.RESULTS The antioxidant activities of four extracts from N.fordii all showed dose-effect relationships,that of ethyl acetate extract was the strongest,while that of ethanol extract was the weakest.They had some correlations with the content of total flavonoids (0.604 ＜ r ＜ 0.638) and significant correlations with the content of total phenols (r ＞ 0.977).CONCLUSION Ethyl acetate extract from N.fordii can be used for the development of natural antioxidants,and the content of total phenols is the main factor to influence its antioxidant activity.

Objective To evaluate laparoscopic appendectomy(LA) and open appendectomy(OA)in obese patients.Methods From January 2008 to November 2010,153 obese patients with appendicitis were operated on,92 cases were treated with initial LA and 61 cases with upfront OA.The operative time,intraoperative bleeding volume,intestinal recovery period,the rate of using acesodyne,major postoperative complications,the duration and hospital cost were studied.Results In LA group,4 cases were converted to open surgery.All the variables in LA group were better than those in OA group except the hospital cost and the differences were statistically significant (the operative time:t =14.0,P ＜ 0.001 ;intraoperative bleeding volume:t =19.7,P ＜ 0.00 1 ;intestinal recovery period:t =12.3,P ＜ 0.001 ;the rate of using acesodyne:t =21.01,P ＜ 0.001 ;main postoperative complications:x2 =40.138,P ＜ 0.001 ;the hospital stay:t=17.3,P＜0.001) except the in-hospital cost(t=1.434,P＞0.05).Conclusions Compared with OA,LA is a better choice for obese patients with appendicitis because of its advantages of minimal injury,early recovery,less complications and short hospital stay.

OBJECTIVETo study the numbers and locations of spermatic veins, testicular arteries, and lymphatic vessels in the spermatic cord of the varicocele patient under the laparoscope.

METHODSFifty-seven varicocele patients received laparoscopic ligation of spermatic veins, during which we recorded the numbers and observed the locations of spermatic veins, testicular arteries, and spermatic lymphatic vessels.

RESULTSDuring the surgery, we identified 3.3 ± 1.2 spermatic veins, 1.4 ± 0.9 testicular arteries, and 4.3 ± 1.1 spermatic lymphatic vessels. No statistically significant differences were observed between the two side in the numbers of the spermatic veins, testicular arteries and spermatic lymphatic vessels (P > 0.05). The testicular arteries were seen on the exterior of the spermatic veins and winding around them, while the spermatic lymphatic vessels mostly between the veins.

CONCLUSIONThe spermatic veins, testicular arteries, and lymphatic vessels in the spermatic cord of the varicocele patient have their specific anatomic characteristics. Laparoscopic identification of these vessels may contribute to the surgical treatment of varicocele.
