AlM:To investigate the visual function in myopia and hyperopia amblyopia whose corrected visual acuity have recovered to normal.METHODS: The visual function of children ( 50 cases ) with amblyopia eyes by binocular vision correction after treatment above 0. 9 was checked. The simultaneous perception, fusion range and distance stereopsis were measured. According to the refractive condition of the children who were divided into group A ( myopia, 20 cases ) and group B ( hyperopia, 30 cases ) . The statistically difference of simultaneous perception, fusion function and stereopsis in two groups was analyzed. RESULTS: Fifteen ( 75%) and twenty - six ( 87%) children got the simultaneous perception in group A and group B respectively, and the differences between two groups were not significant (χ2=0. 454,P>0. 05). Group A had six children ( 30%) and group B had only seven children (23%) with the normal aggregative fusion range, two groups did not show any difference (χ2 =0. 565, P>0. 05). Respectively sixteen (80%),and twenty children ( 67%) had the normal divided fusion range in group A and group B, the recovery rate did not show any significant difference (χ2=0. 740, P>0. 05). Fifteen (50%) and seven ( 35%) patients acquired the far stereoscopic vision in group B and group A respectively, the recovery rate also did not show any significant difference. Normal distance stereopsis of 50 cases had 22 cases ( 44%) , and normal near stereopsis of 50 cases had 13cases ( 26%) Seven (23%) and 6 (30%) children got the normal near stereoscopic vision in group B and group A respectively, and the recovery rate did not show any significant difference (χ2=0. 195, P>0. 05;χ2=0. 295, P>0. 05).CONCLUSlON:After amblyopia treatment, although the children got the normal visual acuity, the binocular vision still can not completely normal in the short term. Myopia and hyperopia factor will not produce significant effect on binocular vision development.

Objective To analyze the impact of medical insurance reimbursement mechanism on the income of urban community health centers run by various entities. Methods The data of the baseline survey of community health centers in 28 cities made in 2007 were called into play. These data were used to compare the percentage of the annual medical insurance income from outpatient clinics of three types of community health centers in their gross annual income and their annual outpatient clinic income. Results For 929 community health centers with income from medical insurance reimbursement, the average percentage of their annual income from outpatient clinic accounts for 24% of their gross annual income and 26. 09% of their annual outpatient income;In respect of the reimbursement rates of medical insurance at outpatient clinics, the highest come from those run by enterprises, secondly those by the government,and the least those run by social organizations or individuals. Conclusion The mechanism of medical insurance reimbursement has already affected the income of the third type of community health centers. It is recommended to raise the coverage rate of medical insurance of such type of centers and their reimbursement rates of medical insurance. This may further consolidate the policies of medical insurance reimbursement.

Objective To study the immune regulation of antisense peptide in rats by observing immune function of activity fragments of thyrotropin receptor (TSHR) and their corresponding antisense peptides. Methods TSHR peptides TR1, TR2, TR3 and their antisense peptides RT1, RT2, RT3, and three pairs of complementary peptides were injected into rats of different groups respectively, and the serum levels of TT_3, TT_4, TSHR antibody (TRAb), thyroid stimmulating antibody, thyroid blocking antibody and TSH antibody (TSHAb) and pathological changes in thyroid tissue were investigated. Results Serum TRAb could be induced when each of three fragments of TSHR was injected into rats; TRAb and TSHAb were induced by RT1 or RT2; epithelial hyperplasia and lymphocytic infiltration observed in thyroid tissue of rats injected with TR2 could be abated by injecting RT2 subsequently. Conclusion The results suggest that all 3 TSHR fragments are shown to be immunogenic and are capable to induce TRAb; both RT1 and RT2 show their effect on immune regulation and are idiotypic of TSHR peptides; On the other hand, the humoural and cell immunities are ameliarated by injection of antisense peptides. Therefore, it is possible that antisense peptides may be involved in immune regulation via immune network.

OBJECTIVE: To evaluate the safety and efficacy of FK506-based dual therapy and CsA-based triple therapy for immunosuppression after liver transplantation. METHODS: The literature about the randomized controlled trials (RCT) on FK506 and CsA for immunosuppression after liver transplantation was retrieved for analysis using RevMan 5.0 software. RESULTS: A total of 7 RCTs were included; 3 were considered as high quality of RCT, 4 as moderate quality. The results of Meta-analysis of FK506-based dual therapy indicated the patients’ survival rate (RR=1.06, 95%CI=0.77~1.45,P=0.72), grafts’ survival rate (RR=0.99, 95%CI=0.76~1.29,P=0.92), infection rate(RR=0.98, 95%CI=0.60~1.58,P=0.93)and incidence of neurotoxicity (RR=0.59, 95%CI=0.32~1.07,P=0.08)was not significantly different. The incidence of acute rejection in CsA group was lower than in FK506 group (RR=1.57, 95%CI=1.23~2.01,P=0.000 3). CONCLUSION: The curative efficacy of FK506 group is not different from that of CsA group in respect of rate of patient/graft, infection but increase the incidence of acute rejection. Because CsA can increase incidence of neurotoxicity, it is suggestion to treat patients of nervous systerm disease with FK506.

AIM: The selective recognition of the sense peptides which are located in special regions of thyrotropin receptor (TSHR) by their corresponding antisense peptides has been investigated. Three pairs of sense and antisense peptides were named TR1 (aa37-45) and RT1 (aa45-37), TR2 (aa353-366) and RT2 (aa366-353), TR3 (aa648-655) and RT3 (aa655-648). METHODS: To prepare three affinity chromatography columns, antisense peptides were immobilized, called RT1-sepharose 4B, RT2-sepharose 4B and RT3-sepharose 4B, respectively and investigate the retardative behavior for each of native peptide TR1, TR2 or TR3 on above columns with stepwise elution. RESULTS: Each of the three immobilized antisense peptides recognized and retarded its corresponding sense peptide-TR1, TR2 or TR3 instead of those non-complementary peptides. Immobilized RT1 recognized free TSHR protein molecule as well. In additional, bovine thyrotropin was recognized by immobilized TR1. CONCLUSION: The results indicate that molecular recognition theory exsits in thyrotropin receptor system. It may be useful to isolate biological molecules and to locate epitopes of TSH on TSHR molecule. Otherwise, antisense peptide may be used for treatment of experimental autoimmunolized thyroid disease (AITD) in the rat. [
