Objective:To investigate the association of human leukocyte antigen (HLA) class Ⅰ (A, B and C), class Ⅱ (DRB1, DQB1 and DPB1) allelic and haplotypic polymorphisms with acute lymphoblastic leukemia (ALL), acute myeloid leukemia(AML) and chronic myeloid leukemia (CML) in Han nationality of southern China.Methods:The peripheral blood samples of 845 leukemia patients (323 cases of ALL, 350 cases of AML and 172 cases of CML) and 745 healthy blood donors from Han nationality of southern China in Shenzhen Blood Center were collected. The HLA-A, -B, -C, -DRB1, -DQB1 and -DPB1 genes were genotyped by using polymerase chain reaction-reverse sequence specific oligonucleotide (PCR-rSSO) and polymerase chain reaction-sequence based typing (PCR-SBT) methods to identify the first 4 digits of HLA alleles. The Arlequin 3.5 software was used to analyze HLA haplotypes. The correlations between HLA allelic and haplotypic polymorphisms and three types of leukemia were statistically analyzed at HLA low-resolution level (the first 2 digits of alleles) and high-resolution level (the first 4 digits of alleles), respectively.Results:P-values were adjusted by Bonferroni correction. In ALL group, the frequencies of A*02 (36.22% vs. 28.26%, χ 2 = 13.41, PC < 0.01) and its haplotype A*02-B*46-C*01 (15.35% vs. 10.23%, χ 2 = 10.90, PC = 0.02), DRB1*12 (15.79% vs. 11.10%, χ 2 = 9.02, PC = 0.03), A*02:03 (9.75% vs. 5.32%, χ 2 = 14.25, PC = 0.002) and its haplotype A*02:03-B*38:02-C*07:02 (3.80% vs. 1.51%, χ 2 = 10.41, PC = 0.02) were higher than those in healthy controls, which implied that these factors could confer risk effect in ALL. In AML group, the frequency of A*11-B*15-C*08-DRB1*15-DQB1*06-DPB1*02 (1.34% vs. 0.07%, χ 2 = 12.54, PC = 0.003) was significantly higher than that in healthy controls, suggesting that the risk effect might be conferred by this haplotype. In CML group, the frequencies of A*02 (36.63% vs. 28.26%, χ 2 = 9.33, PC = 0.02) and its haplotype A*02-B*15-C*04 (2.17% vs. 0.29%, χ 2 = 11.74, PC = 0.02), and DRB1*03:01-DQB1*02:01-DPB1*02:01 (1.86% vs. 0.14%, χ 2 = 13.10, PC = 0.01) were higher than those in healthy controls, which implied that these factors could confer risk effect in CML, whereas the frequency of DRB1*13 (1.45% vs. 5.25%, χ 2 = 9.29, PC = 0.03) was lower than that in healthy controls, suggesting that it was a CML antagonistic gene. Conclusion:Leukemia susceptible or antagonistic HLA alleles and haplotypes are found at low-resolution and high-resolution levels of HLA, which might provide reference for investigating the pathogenesis of leukemia and guiding formulation of effective treatment strategies in Han nationality of southern China.

AIM:To compare the efficiency of fibrin glue to suture technique in pterygium surgery performed with limbal autograft under different methods of anesthesia.
METHODS: A prospective randomised clinical trial was carried out in 60 eyes of 55 patients operated for primary nasal pterygium, which were divided into two groups randomly: experimental group ( 30 eyes in 27 patients ) was under surface anesthesia ( oxybuprocaine ) and control group ( 30 eyes in 28 patients ) was under local anesthesia ( 20g/L lidocaine ). Autologous limbal graft taken from the superotemporal limbus was used to cover the sclera by a fibrin tissue adhesive after pterygium excision. Patients were followed up at least for 6mo. Time of operation, matching degree of graft and VAS score were mainly observed and recorded.
RESULTS: In experimental group the average surgery time was shorter (P=0. 008) and matching degree of graft ( 93%) was better than control group ( 83%) , the differences had statistical significance(P<0.05).
CONCLUSION: The surface anesthesia is enough when using fibrin glue for graft fixation in pterygium surgery, which will shorten surgery time and get better matching degree of graft.

Teaching rounds is an important part of clinical teaching but it is difficult to implement in place for a variety of reasons. To endocrine and metabolic section as an example, Lack of enthusiasm, inadequate preparation and other issues result that teaching rounds is difficult to achieve the desired effect in the teaching rounds, especially in the English teaching rounds. In view of the above situation, based on the concept of PBL to carry out teaching rounds in English is not only an important method to cultivate the clinical thinking of medical students, but also an important measure to improve teachers' and students' English proficiency, as well as to cultivate medical students' clinical thinking. The last but not the least, carrying out teaching rounds in English is an important measure for medical education reform and improve-ment. Facts have proved that carrying out teaching rounds in English has a high practicality and feasibility in clinical practice.
