Chinese Journal of Postgraduates of Medicine 2011;34(9):7-9
Objective To explore the value of serum human epididymis protein 4 (HE4) and cancer antigen 125 (CA125) in the prediction of ovarian cancer onset risk. Methods Petected the expression of HE4 by enzyme linked immunosorbent assay (ELISA) and CA 125 by electrochemiluminescence (ECL) in serum of 75 samples of ovarian cancer (ovarian cancer group),132 samples of ovarian benign disease (ovarian benign disease group) and 30 samples of healthy women (control group),calculated the sensitivity and specificity of HE4 and CA125 in the prediction of ovarian cancer onset risk,and drew receiver operating characteristic (ROC) curve. Results The expression of serum HE4 and CA125 were both higher in ovarian cancer group than those in ovarian benign disease group and control group (P < 0.05 ). HE4 was a better index in the prediction of ovarian cancer onset risk than CA 125 (ROC area under curve was 0.966 and 0.905 respectively). The expression of HE4 was various in different pathological types,serous ovarian adenocarcinoma had the highest expression of HE4 (100.0% ,42/42). The sensitivity of diagnosing ovarian cancer by HE4 was 86.7%(65/75), 93.3%(70/75) by HE4 combining and/or CA125,there was no significant difference(P>0.05).Conclusion Serum HE4 could be a good index of predicting the onset risk of ovarian cancer,the combination of HE4 and/or CA125 could not increase the sensitivity of prediction of ovarian cancer significantly.

Developmental dyslexia is a specific learning disability. The cerebral mechanism of development dyslexia is an important topic that has fascinated many researchers. With the introduction of brain imaging in studies of cerebral mechanism of development dyslexia, many achievements have been made. Studies of developmental dyslexia structure image found that development dyslexia showed brain structure abnormal in the parietotemporal region, occipitotemporal cortex, inferior frontal gyrus, and cerebellum et al, manifesting either in one specific area or by the asymmetry of one area; the functional image studies revealed that development dyslexia showed activity abnormal in most regions that proved to display structure abnormality; studies of brain functional connectivity demonstrates that the abnormality of development dyslexia happened not only in the connection between front-back part in one cerebral hemisphere, but also in the connection between the two hemispheres. In addition, some studies indicate Chinese development dyslexia has different brain mechanisms compared to that of alphabetic languages. These findings provide valuable insight for future developmental cerebral mechanisms research and for the expansion of Chinese development dyslexia research.

Objective To investigate the effects of rosiglitazone on proangiogenesis function of human umbilical vein endothelial cells ( HUVEC) in high glucose environment. Methods HUVECs were cultured in high glucose environment and stimulated by rosiglitazone. MTT, cell scratch test and Transwell assay were used to detect HUVEC proliferation and migration. The concentration of VEGF, SDF-1 was also detected in the supernatant. Results Rosiglitazone could effectively promote HUVEC proliferation and migration. The concentration of VEGF and SDF-1 in rosiglitazone stimulated supernatant was higher than that in high glucose group. The inhibition of AKT signal could block the promotion of rosiglitazone on the HUVEC proliferation, migration and secretion. Conclusion Rosiglitazone could significantly promote HUVEC secretion, proliferation and migration in high glucose environment. AKT signal played an important role in this process.

Objective:To investigate the soldiers' depression after sea field training and influence factors.Methods:1107 navy men were evaluated by Zung's Self-Rating Depression Scale (SDS) and Eysenck personality questionnaire (EPQ) after field training.Results: The rate of depression in the study group was 25.04%, N score of the soldiers after sea field training was significantly higher than the norm of Chinese army men. Logistic regression analysis revealed that the factors of nervousness, dyscoimesis, medical history during sea field training, restless, introversion, the level of education, living environment before joining in the army, hunger and so on had influenced the level of depression.Conclusion:The total incidence of depression in soldiers after sea field training is higher than the norm of army men. It is associated with stress, personality characteristics, training factors, general malaise, psychological pressure and the level of education.

ObjectiveTo evaluate the clinical effect of ultra pulse CO2 laser in treatment of 32 patients with primary amyloidosis of the skin. Methods64 patients with primary amyloidosis of the skin were selected and randomly divided into two groups,the observation group(32 cases)and the control group(32 cases).The observation group were treated with ultra pulse CO2 laser,and the control group were treated by routine medicine method.Clinical effect were compared between the two groups after twelve weeks therapy. ResultsThe total effective rates of the observation group and the control group were 90.6%,53.2% respectively.There were a significant difference between the two groups(x2 = 11.13,P<0.01).There were some different irritations in two groups after therapy,to give symptomatic treatment could help relieve.The relapse rate in the observation group was significant lower than that in control group after treatment of 3 ~ 6 months(x2 = 9.471,P<0.01). ConclusionUltra pulse CO2 laser therapy of primary amyloidosis of the skin was safe and effective.

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.
