In the course of the reform of curriculum system of clinical laboratory medicine,Medical College of Qingdao University takes the innovative thinking training as a master line,practice teaching as the key point,the skill training as the breach,and sticks to the pertinence andpractibility in the curriculum system reform to construct the innovation-centered curriculum sys-tem of clinical laboratory medicine.It also devotes itself to strengthening students’overall quality and training students' innovative thinking,to culture the high-level talented persons of clinical labo-ratory medicine who have the innovative thinking and the stronger adaptiveness for society.

The experimental teaching of morphlogy of bone marrow cytomorphology is the important content in the medical laboratory science.By conducting a series of reforms such as renewing teaching concept,consummating teaching condition,reforming teaching link,recombinating teaching content,establishing examination system about the experimental teaching of bone marrow cytomorphology may remarkably enhance student’s comprehensive ability and teacher’s anthusiasm and build the new type of relationship between teachers and students,which plays an important role in the cultivation of medical laboratory science specialized talents.

Objective To investigate the association between rs1013940 in SLC5A7 and Tourette Syndrome ( TS) in Chinese Han population.Methods Polymorphism was genotyped in 401 TS nuclear fam-ilies trios from china by real-time fluorescent quantitive PCR.Transmission disequilibrium test ( TDT) and Haplotype relative risk ( HRR ) were used to analyze the association between the genetic distrbution of rs1013940 and TS and the results were verified by haplotype-based haplotype relative risk( HHRR) .Results No transmission disequilibrium was found between rs1013940 in SLC5A7 and TS by TDT and HRR( TDT:χ2=0.268, P=0.657, OR=0.728,95%CI=0.366-1.451;HRR:χ2=0.111, P=0.739, OR=0.959,95%CI=0.762-1.466) .HHRR also indicated the same result ( HHRR:χ2=0.276, P=0.599, OR=1.082,95%CI=0.806-1.453) .Conclusion The result reveals that there is no significant association between rs1013940 in SLC5A7 and TS in Chinese Han population.However,the results need to be further validated in different populations.

Objective To investigate the features and characteristics of GLIS3 gene mutation in patients with congenital hypothyroidism(CH),and to establish the theoretical basis for gene diagnosis and prenatal diagnosis of CH.Methods Genomic DNA was extracted from peripheral blood leukocytes of 50 patients with CH who were collected from February 2007 to November 2016 in Shandong Province.The exon 2 to 11 of GLIS3 were amplified with 11 pairs of sequence specific primers designed by Primer 5.0.Polymerase chain reaction and the first generation of sequencing method(Sanger sequencing) were used to detect the mutation.Comparison of the sequencing results with the GLIS3 reference sequence (National Center for Biotechnology Information Reference Sequence:NC_000009.12) helped to screen gene mutations.Results The 50 CH patients included 22 boys and 28 girls,and the sex ratio was 1.0 ∶ 1.3.The mean age was (2.5 ± 0.5) years.Six cases (12％) had thyroid gland hypoplasia,23 cases (46％) had thyroid gland agenesis and 21 cases(42％) with ectopic thyroid gland.C2507A missense mutation was found in exon 10 of GLIS3 in a thyroid gland agenesis case,which might result in proline to glutamine substitution at codon 836.One mutant (rs780019691,c.C289T) was detected which was nonsense mutation (Arg→Stop) in another thyroid gland agenesis child.Conclusions The mutation rate of GLIS3 gene is very low in CH children of Shandong province.Further studies are needed to investigate the relationship between GLIS3 genotypes and clinical phenotypes.

Philadelphia chromosome-positive acute myeloid leukemia is controversial and difficult to distinguish from the blast phase of chronic myeloid leukemia.As a myeloid neoplasm,rare cases of this leukemia manifest multiple soft-tissue tumors or bone lytic lesions.In this paper,we describe a 49-year-old male patient who had an abrupt onset with sharp chest pain,fever,fatigue,emaciation,and splenomegaly.18F-fluoro-deoxy-glucose positron emission tomography/computed tomography (18F-FDG PET/CT) result showed diffuse and uneven hypermetabolic lesions in the bone marrow with peripheral bone marrow expansion,multiple soft tissue neoplasms with high 18F-FDG uptake,and lytic bone lesions.Bone marrow smear and biopsy detected aberrant blast cells expressing myeloid rather than lymphoid immunophenotype marker.For the existence of Philadelphia chromosome and BCR-ABL1 fusion gene together with complex chromosome abnormalities,a diagnosis of Philadelphia-positive acute myeloid leukemia was made,although the type (de novo or blast crisis) remained unclear.
