·Uveitis is an inflammation of any or all parts of the uveal tract including the iris, ciliary body and the choroid. Despite current advances in diagnosis and management, visual loss occurs in 35%-45% of patients with uveitis. The etiopathogenesis of uveitis remains unknown; it may be associated with environmental and immunogenetic factors. Many studies have demonstrated polymorphisms in major histocompatibility complex (MHC) genes may determine involvement in uveitis. Recently polymor-phisms in non-MHC genes, including cytokine and che-mokine genes, have been reported to play important roles in the pathogenesis of uveitis. This article reviewed the advances in the studies on cytokine and chemokine gene polymorphisms associated with uveitis.

AIM: To evaluate the efficacy and complications of intravitreal injection of triamcinolone acetonide ( TA ) for the treatment of macular edema caused by pre-retinal membrane of the macular.
METHODS: Totally 23 patients ( 24 eyes ) with macular edema caused by pre-retinal membrane of the macular were treated withintravitreal injection of 4mg TA. Best-corrected visual acuity ( BCVA ) , intraocular pressure ( IOP ) , slit - lamp examination, fundus fluorescein angiography ( FFA ) and optical coherence tomography (OCT) were performed before and after treatment. The SPSS 12. 0 software was used for statistical analysis.
RESULTS: After 10, 30, 90d of treatment of TA, as compared with before treatment, visual acuity improved significantly ( P<0. 05 ), and central macular thickness (CMT) was significantly thinner (P<0. 01). The average central macular thickness decreased from 522 ± 126μm before treatment to 264±115μm, 245±128μm, 286±131μm at 10, 30, 90d after treatment. Macular edema reduced. IOP increased in 7 eyes ( 29%) , one cataract case, no other complications associated with vitreous injection.
CONCLUSION: Intravitreal injection of TA in the treatment of macular edema caused by pre - retinal membrane of the macular is simple, safe and easy to operate. It can quickly reduce macular edema, and improve the visual acuity in the short term. Part of patients may recur after injection in the first half of the year.

Objective To systematically review the efficiency of 18 F-FDG PET in glioma grading by using Meta-analysis. Methods Retrieval in PubMed and China National Knowledge Infrastructure (CNKI)was performed. Relevant papers concerning with glioma diagnoses with 18 F- FDG PET were selected. Paper quality was evaluated according to the standard of diagnostic test recommended by Cochrane Workshop. The data of glioma malignancy degree defined as semi-quantitatively and qualitatively were extracted from the papers. Meta-analysis was conducted with the Meta-Disc software to calculate pooled weighted sensitivity and specificity with 95% confidence interval (CI). Summary receiver operating characteristic (SROC) curve was performed and the areas under the curve (AUC) were calculated. Results Seven hundred and fifty-three patients from 17 papers ( 16 in English, 1 in Chinese) were included. Two hundred and seventy-two patients from 11 papers were using semi-quantitative (tumor to cortex ratio, T/C; tumor to white matter ratio,T/W) method and 481 patients from 9 papers were using qualitative method (visual observation, some of the papers had 2 or more methods). After heterogeneity test was done, different effect models were selected. The pooled weighted sensitivity, specificity and diagnostic odds ratio (DOR) with 95% CI for T/C group was 0. 952 (95% CI: 0. 903 -0. 980), 0. 409 (95% CI: 0. 318-0. 504) and 11. 746 (95% CI:5. 368-25. 702) respectively. The pooled weighted sensitivity, specificity and DOR with 95% CI for T/W group was 0. 857 (95% CI: 0. 768-0. 922), 0. 538 (95% CI: 0. 431 -0. 642) and 22. 066 (95% CI:7. 077-68. 800) respectively. The pooled weighted sensitivity, specificity and diagnostic odds ratio (DOR)with 95% CI for qualitative method was 0.810 (95%CI: 0.757-0.855), 0.870 (95%CI: 0. 819-0.911 ) and 15.282 (95% CI: 3. 716-62. 851 ) respectively. The AUC for T/C group, T/W group and qualitative method was 0.8604, 0. 8373 and 0. 8724 respectively. Conclusions Grading glioma by 18 F-FDG PET with semi-quantitative method may provide high diagnostic sensitivity. If qualitative method is used, the diagnostic specificity may be higher.

Objective To study the process of foam fractionation of polyphyllin in semi-batch mode. Methods Taking enrichment ratio, recovery rate of polyphyllin, and purity ratio as the performance criteria and using single examining method to examine the operational parameters, i.e. operation mode, air flow rate, initial feed concentration, solution pH value, initial feed height and temperature on separation performance. The optimal conditions of the process were obtained finally. Results The separation performance is good when gas flow rate is 400 mL/min, initial feed concentration (polyphyllins content) is 0.3 mg/mL, pH value is 7, feed height is 30 cm, and feed temperature is 40 ℃. The enrichment ratio is 25.7, recovery ratio is 42.1%, and the foam liquids purity of total polyphyllin is 41.4%, which is 4.5 times higher than that in feed purity. Conclusion Foam fractionation technique could be applied to separate polyphyllin.

Objective To evaluate the value of diffusion-weighted imaging (DWI)in diagnosing the acute centrum ovale infarction, and also to investigate the pathogenesis of the infarction. Methods All 58 patients underwent conventional MRI and DWI scanning after symptoms’ onset. DWI findings were compared to the findings of T_1WI and T_2WI. Results The sensitivity and specificity in diagnosing the ischemia stroke were 96.4% and 98.8% within 7 days after onset. Of all the cases, 62.1% were associated with the cerebral large-vessel disease and emboligenic heart disease. Only 36.2% had a classic lacunar syndrome but 69.0% had more frequently an abrupt onset of symptoms. Conclusion DWI is of high accuracy for diagnosing centrum ovale infarction and detecting early infarction lesions which are difficult to be displayed in conventional MRI, and very helpful in differentiating the acute from non-acute lesions; symptomatic centrum ovale infarction is suggested to be associated with large-vessel and heart disease which should be distinguished from the lacunar infarcts.
