Objective To observe the cerebral protective effects of monomial four hexose ganglioside combined with compound salvia miltrorrhiza tablets (CSMT) in patients with refractory epilepsy. Methods 80 patients with refractory epilepsy patients treated in our hospital between January 2010 and October 2015 were randomly divided into control group and treatment group. The control group patients were treated with conventional antiepileptic drug therapy, and the treatment group patients were treated with monomial four hexose ganglioside, CSMT and conventional antiepileptic drug therapy. The efficacy in two groups' patients was determined after a course of treatment. The IQ and memory quotient in two groups' patients before and after treatment were evaluated by the Wechsler Adult Intelligence Scale (WAIS-RC) and the Wechsler Memory Scale (WMS-RC) respectively and comparative analysed. Results ①The total effective rate in the treatment group (97.5%) was significantly higher than that in the control group (87.5%) (P<0.05). ②The verbal IQ (95.4±8.5), performance IQ (94.8 ± 12.5), total IQ (92.8 ± 7.5) and memory quotient (93.5 ± 8.2) scores in the treatment group after treatment were significantly higher than those before treatment (89.5 ± 7.2), (91.5 ± 10.1), (88.5 ± 6.9), (82.5 ± 10.0) respectively, and also were significantly higher than those in the control group after treatment (75.4 ± 6.8), (80.6 ± 9.8), (80.1 ± 5.9) and (76.9 ± 8.2) respectively (P<0.05). The IQ and memory quotient in the control groups' patients after treatment were significantly decline and lower than before treatment, which had a statistically significant difference (P<0.05).

Objective To study the measurement differences of central corneal thickness(CCT) in different degree of myopia by Sirius and ultrasound pachymetry(UP). Methods 225 myopic subjects(450 eyes)were recruited and divided into three groups according to the degree of refractive errors. The CCT were obtained from the eyes for each subjects using the Sirius and UP. Data were compared by using paired t-tests and the Pearson correlations. Bland- Altman analysis of all pairs were determined. Results The mean CCT in low myopic group obtained from Sirius and UP were (542.61±29.19)μm and(538.51±29.12)μm,respectively. The mean CCT in medium myopic group by Sirius and UP were(543.96±27.02)μm and(540.98±26.56)μm.The measured mean CCT in high myopic group were(547.25±22.53)μm and(542.19±21.64)μm by Sirius and UP. The mean CCT measurements between the two instruments were high correlated and statistically different(P<0.05) in the three groups respectively. In different myopia groups Sirius has good coincidence with UP in measuring CCT according to the Bland-Altman plot. Conclusion In vast majority of cases,Sirius can replace traditional UP in measuring CCT. But for the preopreative examination of the high myopia patients, we need to think twice about the difference between the two measurements.
