To analyze the effect of pre-surgical status on the post-surgical stereopsis in surgically aligned adult con-comitant strabismus.By using Titmus and Randot stereo tests,we measured near stereo acuity of 99 adults who had constant exotropia and were successfully aligned by surgery.A covariance analysis showed that the post-surgical stereo acuity was significantly determined by the type of strabismus (i.e.,whether that's intermittent or not;P =0.001),the duration of pre-surgical exotropia (P =0.002)and the year on-set (P =0.048)but not by the pre-surgical deviation (P =0.133).We conclude that the stereopsis of adult concomitant strabismus can be reestab-lished by surgery,while the extent of such an improvement is determined by the type of strabismus,the duration of pre-surgical exotropia and the year on-set of patients.

Objective:To establish an efficient method for expression and purification of vMIP-Ⅱ which encoded by a viral gene and ho-mogued human chemokine in active single strand in E.coli cells. Methods: Cloning with bi-enzyme restriction and lysising bacteria with cold osmoic shock were used for expression,MBP affinity chromatography of fusion protein and self-selective of recombinative peptide for final purification. The expressing and purifying products were detected with SDS-PAGE and Western blotting and identified with inhibitory adhesion experiment for its activity.Results: Fusion protein MBP-vMIP was effeciendy expressed in E. coli at secretive type, and self-cleaved to sparate the vMIP-Ⅱ. The final product single strand vMIP-Ⅱ was active for blocking chemokine receptor CCR5.Conclusion:This is an effective method for obtaining viral chemokine vMIP-Ⅱ of recombinant single strand.The recombinant vMIP-Ⅱ may be useful for the study of diseases involving in chemokiine receptors such as HIV infection,rejection of transplantation and chronic inflammation,etc.

Objective To investigate the relation between plasma macrophage migration inhibitory factor(MIF) concentration and the activity of activator protein-1(AP-1) in peripheral blood and coronary heart disease(CHD),and their relation with coronary arteriosclerosis plaques in patients with CHD.Methods One hundred and forty two patients were divided into coronary heart disease(CHD) group(n=107) and control group(n=35) according to coronary angiographic(CAG) result.The CHD group was further divided into stable angina pectoris(SAP) group(n=33) and acute coronary syndrome(ACS) group(n=75) according to clinical manifestations.In addition,according to the type of coronary lesions,the CHD group was further divided into the type A lesion(n=30) group,type B group(n=48) and type C group(n=29).According to the degree of coronary stenosis,the CHD group was also divided into mild stenosis group(n=21),moderate stenosis group(n=31) and severe stenosis group(n=55).The amount of Phospho-c-Jun in lysate and plasma MIF concentration were measured by enzyme-linked immunosorbent assay(ELISA).The results of Phospho-c-Jun was demonstrated with absorbance.Which reflect the amount of AP-1.Results The absorbance of Phospho-c-Jun in the CHD group was higher than that in the control(1.43?0.33 vs 0.71?0.13,P

A total of 60 myopia patients (120 eyes) who were going to undergo myopia LASIK were selected in this study. The patients were divided into two groups of anisometropia and non-anisometropia,each group had 30 patients (60 eyes). Checked vision, fusion range,near and distant stereoscopic at 10 day pre-operation and at 1,3 and 6 month in post operation. After the LASIK, all of 60 patients' anisometropia were significantly reduced, binocular stereopsis were obviously improved than pre-operation, especially the anisometropia group; the binocular fusion range also got better,but there was no significant difference between the two groups. This study clarified that the visual function of anisometropia could be improved after LASIK.

Objective: To investigate the coverage of enterovirus 71 (EV71) vaccine among children born between 2018 and 2021 in Ningbo City, Zhejiang Province, so as to provide insights into formulating EV71 vaccination strategy. Methods: Data pertaining to demography and EV71 vaccination among children born between 2018 and 2021 in Ningbo City were obtained from the Zhejiang Immunization Information Management System, and the coverage of vaccination, full-dose vaccination and timely vaccination of EV71 vaccine were analyzed. Results: Totally 416 176 children were born between 2018 and 2021, including 216 977 boys (52.14%) and 199 199 girls (47.86%). The coverage rates of vaccination, full-dose vaccination and timely vaccination was 61.50%, 58.70% and 32.53%, respectively. The coverage rates of vaccination, full-dose vaccination and timely vaccination among local children (71.43%, 70.04% and 40.24%) were higher than those among migrant children (54.05%, 50.18% and 26.73%; P<0.05). The coverage rates of vaccination, full-dose vaccination and timely vaccination among urban children (67.72%, 65.06% and 40.37%) were higher than those among rural children (54.11%, 51.14% and 23.21%; P<0.05). The coverage rates of vaccination were 54.98%, 61.24%, 65.10% and 66.72%, the coverage rates of full-dose vaccination were 52.16%, 58.72%, 62.44% and 63.39%, and the coverage rates of timely vaccination were 22.47%, 25.86%, 39.14% and 48.03% by the born year from 2018 to 2021, all showing increasing trends year by year (P<0.05). Conclusion The coverage of vaccination, full-dose vaccination and timely vaccination of EV71 vaccine appears a tendency towards a rise among the 2018-2021 birth cohorts in Ningbo City, while the coverage of timely vaccination need to be improved.
