Objective:To determine the valproate concentration in plasma of epilepsy patients by HPLC, and compare with the re-sults of chemiluminescence microparticle immunoassay ( CMIA) to evaluate the consistency of the two methods. Methods:HPLC and CMIA was respectively applied to determine the plasma concentration of valproate in 230 epileptic patients. The correlation of the two methods was studied by Passing-Bablok regression and Bland-Altman method. Results:The regression equation of the determination re-sults of HPLC (Y) and CMIA (X) was Y=1. 069 7X+2. 338 2 (R2 =0. 969, n=230), which showed promising correlation. Bland-Altman analysis showed that the consistency of the two methods was poor, and the values of HPLC were higher. Conclusion: HPLC and CMIA used for the determination of valproate plasma concentration show good correlation. However, the consistency is poor and there is system error. In the clinical treatment, adjustment and choice should be paid more attention.

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.

Objective To establish a high performance liquid chromatography (HPLC) method for determining phenytoin concentration in epilepsy patients' plasma,and compare this method with chemiluminescence microparticle immunoassay (CMIA),and to evaluate the consistency of the two methods.Methods HPLC and CMIA methods were applied to determine the plasma concentration of phenytoin in 60 epileptic patients,respectively.The difference of results was analyzed by two-side paired t-test,and then the correlation and consistency of the two methods were investigated with Passing-Bablok regression and Bland-Altman method.Results There was no significant difference between the results of the two methods (P ＞0.05).The regression equation of the determination results by HPLC (Y) and CMIA (X) was Y=0.992 9X +0.143 7 (R2 =0.992 6,n =60),which indicated the correlation of the two methods was good.Bland-Altman analysis showed that the consistency of the two methods for determining was good.Conclusion HPLC and CMIA method in monitoring plasma concentration of phenytoin have good correlation and consistency.Both methods can be used for therapeutic drug monitoring of phenytoin.

· AIM: To study the in situ relative intraocular position of the iris-claw phakic intraocular lens (PIOL)for high myopia using an anterior chamber optical coherence tomography (AC OCT)prototype.· METHODS: Six PIOLs (11.50 to 22.00D lens powers) were implanted in phakic myopic eyes. Using AC OCT, tomography was taken in the anterior chamber to measure the preoperative anterior chamber depth, postoperative distance between the PIOL and the corneal endothelium (endothelial-optic distance), and the postoperative distance between the PIOL and the crystalline lens.· RESULTS: Preoperative anterior chamber depth ranged from 3.27 to 3.91 mm and the postoperative endothelial-optic distance measured 2,07 to 2,24 mm. The distance between the crystalline lens and the posterior surface of the IOL ranged from 0.82 to 1.32 mm. Several tomography revealed the position of the PIOL on the iris, The pigment layer of the iris did not seem to be disturbed by the presence of the PIOL.· CONCLUSION, The original anterior chamber depths were reduced by 36,1% to 44.6% after implantation. This study of 6 eyes revealed that tomography taken by AC OCT are useful in verifying the intraocular position of the PIOL within the anterior chamber. Adequate space was maintained between the iris-fixated phakic intraocular lens and the corneal endothelium, angle, and crystalline lens.

AIM: To analyze the composition, distribution and characteristics of the elderly primary ocular tumors.
METHODS: This was a retrospective study and all 504 cases with primary ocular tumors aged 60 years or older were collected in Shanxi Eye Hospital, during the year 2000- 2012. The onset age, location and pathological pattern were analyzed.
RESULTS: There were 346 cases of benign ocular tumors (68. 7%), and 158 cases of malignancy (31. 3%). Papillomas was the most common type of the benign with 83 cases (16. 5%), followed by a variety of inflammatory cysts and lesions with 69 cases ( 13. 7%) and 64 cases (12-7%) respectively. Among malignant tumors cases, eyelid basal cell carcinoma originated from epithelial was the most common with 72 cases (14. 3%), followed by skin appendages sources malignant tumors with 39 cases (7. 7%). Concerning the location of ocular tumors, there were 282 cases of eyelid tumor (56. 0%) occupied the first position followed by conjunctival tumor with 157 cases (31. 2%).
CONCLUSION: The prevalence and type of primary ocular tumor in elderly people are significant differences from the general population and children's, and the proportion of malignant tumors tended to increase along with the increase of age.

AlM:To compare the differences of tilt and decentration of two aspheric posterior chamber intraocular lens ( PC-lOL) implantation by ultrasonic biomicroscope ( UBM) .METHODS:Thirty-seven patients ( 45 eyes ) underwent cataract surgery were distributed to two groups randomly. Group A was implanted with Akreos AO ( Bausch &Lomb; four-haptic ) while group B implanted with ZCB00 ( Abbott Medical Optics, lnc. AMO; two-haptic) . All eyes underwent standard phacoemulsification with intraocular lens implantation. Diameter of capsulotomy was recorded. One month postoperatively, vision, best-corrected visual acuity ( BCVA) assessment, slit lamp examination, and anterior chamber depth ( ACD ) measured by UBM were performed. Tilt and decentration were measured horizontally and vertically, and total tilt and decentration were calculated by geometry method.
RESULTS:No statistical difference was found in BCVA and diameter of capsulotomy between two groups ( P>0. 05). The mean ACD of group A and group B were 3. 86mm ± 0. 31mm and 4. 14mm ± 0. 31mm respectively, which showed it had statistically significant difference ( P<0. 05). Horizontal decentration, vertical decentration and total decentration of group A were 0. 15mm ± 0. 09mm, 0. 15mm ± 0. 12mm and 0. 22mm ± 0. 12mm respectively, while it were 0. 22mm ± 0. 21mm, 0. 14mm ± 0. 15mm, 0. 29mm±0. 22mm for group B. Horizontal tilt, vertical tilt and total tilt of group A were 0. 63°±0. 62°, 0. 89°±0. 85°and 1.22°±0.76°, while it were 1.36°±1.48°, 1.46°±1.62° and 2. 21°±1. 97° for group B. No statistically significance was found in tilt and decentration between group A and group B, no matter horizontally or vertically or totally (P>0. 05).CONCLUSlON:Two-haptic lOL shows no difference in tilt and decentration with four-haptic lOL postoperatively.
