AMD is a multifactorial disease, and major risk factors include increasing age, current smoking, previous cataract surgery, environmental factors, nutritional factors, genetic markers through genetic regulate complement, lipid, angiogenesis and extracellular matrix. In addition to treatment, epidemiology, risk factors and genetics research of AMD have been significantly progressed. This article will review risk factors of AMD.

In the past, the ways to amblyopia neural mechanism research are given priority to visual electrophysiology and so on, which express the result use two -dimensional form, these ways mainly research the functions of the state before the lateral geniculate body. For the study of optic center, animal models are used to research it. But these kinds of methods are unable to accurately detect amblyopia neural mechanisms of human beings. Vulnerable to a variety of factors, it is difficult to finish the amblyopia treatment effect evaluation. Functional magnetic resonance imaging ( fMRI ) can reflect the three-dimensional visual cortex neuron activity noninvasively and accurately, and give rise to amblyopia neural mechanism and therapeutic effect evaluation. Therefore, in this paper, the amblyopia neural mechanisms and visual center after treatment effect evaluation of fMRI research progress are summarized.

Objective To study the inter-allelic recombination event occurring in the HLA-C locus in a family of Chinese Han nationality, and to evaluate the molecular genetic background of the new HLA allele.Methods Peripheral blood samples were collected from a Chinese leukemia woman patient, as well as her healthy parents and two brothers.HLA-A, C, B, DRB1 and DQB1 alleles were typed by high-resolution PCR-sequence-based typing (SBT) method using Atria Genetic AlleleSEQR HLA SBT kits.The Protrans S4 HLA-C single allele-specific sequencing strategy was used to separate the two HLA-C alleles and to determine novelty of the allele.The full length sequences of HLA-C alleles of the patient and her parents were further analyzed using cloning and haplotype sequencing method. The HLA five loci linked haplotypes and the recombination site were analyzed by family study, meanwhile the full length sequences of the five HLA-C alleles were compared with the IMGT/HLA database by the program BLAST.Results The two haplotypes of the father and mother were a:A*0207-C*010201-B*550201-DRB1*090102-DRQ1*030302 and b:A*240201-C*120202-B*5201-DRB1*1502-DRQ1*0601, c:A*300101-C*060201-B*130201-DRB1*0405-DRQ1*0401 and d:A*110101-C*070201-B*4001-DRB1*080302-DRQ1*0601,respectively.The two brothers inherited their parent′s haplotypes a, d and b, c respectively.The two haplotypes of the patient were the maternal c and paternal recombinant a/b haplotype.The recombinant a/b haplotype A*240201-C*new-B*550201-DRB1*090102-DRQ1*030302, A*240201 came from the paternal haplotype b,while B*550201-DRB1*090102-DRQ1*030302 came from the other paternal haplotype a.When comparing the full length sequences of the HLA-C new allele with the father′s allele C*010201 and C*120202, it could deduce that the recombinant a/b haplotype derived from a recombination event occurring between the paternal chromosome 6 during meiosis.The crossover site was between genomic nt273 and nt330 of HLA-C alleles, which created a HLA-C new allele and the fifth haplotype of the family, and inherited it to the patient.The full length sequences of the new allele had been submitted to Genbank, and officially named C*0121 by WHO nomenclature committee.Conclusion This study demonstrates a rare inter-allelic recombination event occurring in the HLA-C locus within a Chinese Han family and illustrates the process of novel allele and haplotype, and provides direct theory for further studying the mechanisms of gene recombination and HLA polymorphism.

Objective To explore the application value of uric indicant monitoring on patients with impaired glucose tolerance. Methods 9 6 health examination people were selected who with glucose tolerance impairment diagnosis standard population in Jan to Feb 2015 in LaiZhou,There were no significant differences in age and sex composition between the two groups in 48 cases of experimental group and 48 cases in control group.There were no other diseases,and no drugs were taken to con-trol blood glucose.IGT patients in the experimental group using uric indican monitoring to establish personal diet guide, while the control group used normal health education guidance,the two groups respectively before experiment and at the end of detecting urinary indican,fasting blood glucose,2h glucose tolerance levels,and were compared.Results According to the findings of the two groups follow up and the experimental data collected during one year,at the end of the experiment the IGT patients in the experimental group levels of urinary indicant was (50.7±6.2 mg/L vs 78.5±7.9 mg/L),fasting blood glucose was (6.34±0.11 mmol/L vs 6.91±0.29 mmol/L),2h glucose tolerance was (7.81 ± 0.52 mmol/L vs 9.57 ± 1.13 mmol/L)which was lower than the control group.There was significant difference between two groups (t=2.0,2.6, 3.06,P<0.05).Compared with IGT in the experimental group at the end of the experiment,the level of uric indican was (50.7±6.2 mg/L vs 78.3±8.1 mg/L),fasting glucose was (6.34±0.11 mmol/L vs 6.78±0.19 mmol/L),2h glucose tol-erance was (7.81±0.52 mmol/L vs 9.33±0.93 mmol/L)was lower than before the start of the level (t=2.01,2.28, 2.83,P<0.05),and the difference was statistically significant.In terms of the outcome of the various stages of diabetes, IGT patients in the experimental group was significantly better than the control group (χ2=10.85,P<0.05),the difference was statistically significant.Conclusion Through the determination of uric indican to guide the glucose tolerance decrease in patients with a reasonable diet,is conducive to glucose tolerance in the patients with impaired on blood glucose control,can effectively reduce the glucose tolerance decrease (IGT)conversion to diabetes mellitus (DM),change to a positive direction.

The initial study of the tumour DNA fingerprints using MYO minisatellite DNA probe wascarried out,and then,by means of DNA recombinant techniques,the fragment of MYO min-isatellite DNA probe obtained from plasmid pUC19-MYO was inserted into plasmid pGEM-4Z containing RNA polymerase promotor,thus a sub-clone refferred as pGEM-4Z-MYOwas constucted.That made an offer of the conditions of preparing RNA probe in order to in-cerase the sensitivities of DNA fingerprinting and laid a foundation for raised the efficiency of de-tecting the polymorphism of the minisatellite DNA.

Objective To study the role of Ginsenoside Re and Rb3 on mice with viral myocarditis (VMC) and explore the mechanisms. Methods BALB/C mice were infected by coxsackievirus B3 ( CVB3) to establish VMC model. The mice were divided into control group,virus group and Ginsenoside Re and Rb3 treatment group(treatment group). On day 5,day 10,day 20 after infection,the level of serum crea-tine phosphokinase-MB( CK-MB) was detected. Then myocardial sections stained with Masson′s trichrome were used to observe the distribution of mice myocardial collagen fibers, quantify collagen volume fraction (CVF),and detect the levels of superoxide dismutase(SOD). Results (1)The level of CK-MB peaked on day 5,and decreased afterwards[day 5:(463. 68 ± 47. 62) U/L; day 10:(588. 81 ± 56. 09) U/L; day 20:(340. 48 ± 58. 22) U/L,respectively]. While the levels of CK-MB in treatment group were lower than those in virus group[day 5:(378. 69 ± 56. 02) U/L;day 10:(452. 56 ± 67. 78) U/L; day 20:(327. 13 ± 47. 20) U/L,respectively] in the same point. There were significant differences between groups on day 5 and day 10 (P<0. 01). (2) In viral group,the blue staining degree gradually increased with time in myocardial sections stained with Masson′s trichrome,especially in myocardial necrosis area. Compared with treatment group,CVF increased significantly in virus group on day 10 and day 20 ( day 10:6. 52% ± 2. 34% vs. 8. 94% ± 1. 67%;day 20:7. 00% ± 1. 53% vs. 10. 46% ± 1. 74%,P<0. 01). The levels of SOD in myocardial sections in virus group were lower than those of control group[day 5:(48. 83 ± 17. 74) U/L;day 10:(61. 41 ± 14. 58) U/L;day 20:(66. 26 ± 18. 97) U/L,respectively,P<0. 05],but in treatment group,the level of SOD could beimprovedsignificantly[day5:(72. 07 ±24. 85)U/L;day10:(83. 22 ±19. 52)U/L;day20:(92. 00 ± 20. 46) U/L, respectively, P < 0. 05]. Conclusion Because of the inhibition of oxygen radicals and oxidative stress, Ginsenoside Re and Rb3 can protect myocardial tissue. Ginsenoside Re and Rb3 can effectively reduce the extent of myocardial fibrosis. The mechanism may be related with the reduced peroxide level in vivo.
