Background Researches have suggested that the defocus can induce the change of static visual acuity,but whether it produce influence on dynamic visual acuity is not clear.Objective This study was to investigate the impact of myopic defocus on static visual acuity and dynamic visual acuity and explore the essential difierence between static visual acuity and dynamic visual acuity. Methods Forty volunteers were enrolled in this trial.including 20 adults with the age of 27.4±1.64 years and 20 children with the age of 11.70+1.49 years.All the eyes of subjects received regular examined to excluded the eye disease with the best corrected vision of ≥1.0 D,astigmatism of ≤0.75 D and anisometropia ＜1.50 D.+1.00 D,+1.50 D,+2.00 D,+2.50 D slasses were ware respectively for the defocus on the foundation of full correction.Dynamic visual acuity was inspected by using selfmade DVA-I training software.and static visual acuity wag tested by static visual acuity chart (Precision Vision,CAT.NO.2125).This clinical trial complied with the Helsinki Declaration and obtained the approval of Ethic Committee of Wenzhou Medical College.Written informed consent was received from each individual prior to the protocol. Results The dynamic and static visual acuities were gradually decreased with the elevation of defocus (F=506.907,P=0.000).No significant differences were found between static visual acuity and dynamic visual acuity in adult or children at various defocus(P＞0.05).The regression linear analysis showed that a positive correlation between static visual acuity with defoeus(R2=0.819,t=26.72,P=0.000) or dynamic visual acuity with defoeus(R2=0.826,t=27.42,P=0.000).The slope and intercept between defocus with static visual acuity were steeper than that between defocus and dynamic visual acuity (slope:F=34.18,P=0.000;intercept:F=1005.56,P=0.001). Conclusion The effect of defocus on static visual acuity is different from that of dynamic visual acuity.It could be speculated that dynamic visual acuity is related not only to refractive systems but also other factor.

Background: There are obvious changes in neuropeptides from plasma and cerebrospinal fluid in patients with vascular dementia (VaD), and regulating the levels of neuropeptides is a key for prevention and treatment of VaD. Objective: To observe the clinical efficacy of moxibustion at head-points in treatment of vascular dementia (VaD), and assess its effects on memory-related neuropeptides. Design, setting, participants and interventions: A total of 65 VaD patients from Acupuncture Hospital, Anhui University of Traditional Chinese Medicine, were randomly divided into moxibustion group (33 cases) and Western medicine group (32 cases). Patients in the moxibustion group were treated with indirect moxibustion with common monkshood cake for 20 min. Patients in the Western medicine group were orally administered piracetam tablets, 0.8 g for three times a day. One treatment course was 4 weeks, and they were treated for 4 treatment courses. Main outcome measures: The scores of Hasegawa's Dementia Scale (HDS), Mini-Mental State Examination (MMSE), and Activity of Daily Living Scale (ADL), as well as the levels of learning and memory-related neuropeptides from cerebrospinal fluid such as somatostatin (SS) and arginine vasopressin (AVP) were measured before and after treatment in the two groups. Results: Total response rate was significantly higher in the moxibustion group than in the Western medicine group (P<0.01). There were significant differences in scores of HDS, MMSE and ADL between before and after treatment in the two groups(P<0.05 or P<0.01). After treatment, the scores of HDS, MMSE and ADL in the moxibustion group were more improved as compared with those in the Western medicine group (P<0.05 or P<0.01). The levels of SS and AVP after treatment were higher than those before treatment in the two groups(P<0.01). After treatment, the increased levels of SS and AVP were higher in the moxibustion group than in the Western medicine group (P<0.01). Conclusion: Moxibustion is effective in improving the clinical symptom scores and regulating the levels of neuropeptides associated with learning and memory in VaD patients.
