Objective To investigate the association between single nucleotide polymorphism (SNP) of macrophage migration inhibitory factor (MIF) gene-rs1007888 and the pathogenesis of gestational diabetes mellitus (GDM).Methods A total of 120 GDM pregnant women (GDM group) and 165 healthy pregnant women (control group) from Affiliated Hospital of Medical College,Qingdao University were recruited from June 2011 to July 2012.Their age,gestational week,height and weight were recorded.The levels of fasting blood glucose (FBG) and fasting insulin (FIN) were determined.Body mass index (BMI),the hemeostasis model assessment-insulin resistance (HOMA-IR) and hemeostasis model assessment-β cell function (HOMA-β) were calculated.DNA was extracted from fasting blood samples.SNP of MIFrs1007888G/A was determined by DNA sequencing.The FBG,FIN,HOMA-IR and HOMA-β were compared between GDM group and the control group.They were also compared among pregnancies withdifferent genotypes.Results (1) GDM group had higher FBG,FIN and HOMA-IR levels,but lower HOMA-β than the control group (all P ＜ 0.05).(2) MIF-rs1007888 SNP genotype frequencies of GG,GA and AA were 37.5％,45.8％ and 16.7％,and the allelic frequencies of G and A were 60.4％,39.6％ in GDM group; However,in the control group,the frequencies of GG,GA and AA were 26.1％,54.5％ and 19.4％,and the allelic frequencies of G and A were 53.3％,46.7％,respectively.The distributions of MIF genotypes in GDM patients were significantly different from the healthy subjects (P ＜ 0.05).No significant difference of MIF-rs1007888 allele distributions was observed between GDM group and the control group (P ＞0.05).(3) The FBG,FIN and HOMA-IR in pregnant women with GG genotype were statistically higher than those with GA or AA genotypes,while HOMA-β was lower in women with GG genotype (all P ＜0.05).Conclusions The SNP of MIF rs-1007888 was related to the insulin resistance and pancreatic β cell function of pregnant women.GG genotype of MIF-rsl007888 might be a genetic susceptible factor in the pathogenesis of GDM.

Objective To investigate the genotypic and allele frequency differences of melatonin receptor 1B (MTNR1B)-rs4753426 between gestational diabetes mellitus (GDM) pregnancies and normal pregnancies , and to explore the association between single nucleotide polymorphism ( SNP ) of rs4753426 and gestational diabetes mellitus.Methods Totally 93 GDM pregnancies and 165 normal pregnancies were recruited from the Affiliated Hospital of Qingdao University.The age, gestational weeks, height, early pregnant weight , and the levels of fasting plasma glucose ( FPG) , fasting insulin ( FIN) were determined in every participants.By using PCR and DNA sequencing , we detected the distribution of the rs 4753426 genotypes and alleles in all individuals.The homeostasis model assessment-insulin resistance ( HOMA-IR) and the homeostasis model assessment-βcell function ( HOMA-β) were calculated.The allele and genotype frequencies and the FPG , FIN, body mass index ( BMI) , HOMA-IR, HOMA-βlevels between GDM group and control group were compared.Results (1) The genotype frequencies in the GDM group and the control group of rs4753426-CC, CT, TT were 72.0% (67/93), 21.5% (20/93), 6.5% (6/93), and 53.9%(89/165), 40.0% (66/165), 6.1% (10/165) respectively.The allele frequencies in the GDM group and the control group of T and C were 17.2% ( 32/186 ) , 82.8% ( 154/186 ) and 26.1% ( 86/330 ) , 73.9% ( 244/330 ) respectively.There were statistical differences in genotype frequencies and allele frequencies between two groups ( all P<0.05 ).( 2 ) The levels of FPG , FIN and HOMA-IR in the GDM group were obviously higher than those in the control group (P<0.05).The level of HOMA-βwas lower in the GDM group than that of the control group (P<0.05).(3)The FPG of CC and CT genotypes was higher than that of TT genotype in the GDM group (P<0.05), while the level of HOMA-βwas lower than that of TT genotype (P<0.05).Conclusions The MTNR1B-rs4753426 SNP is associated with the pathogenesis of GDM, and rs4753426 is the predisposing locus of GDM.The C-allele is the susceptibility allele of GDM.

OBJECTIVE: To investigate the expression of hyperpolarization-activated cyclic nucleotide-gated cation channel 4 (HCN4) and connexin43 (Cx43) in the sinoatrial node of electric shock death. METHODS: As experimental group, 34 cases of electric shock death who had definite current mark evidence were selected from pathology department of Xuzhou Medical College from 2010 to 2013. As the control group, 20 cases of fatal severe craniocerebral injury in traffic accidents were chosen. The expressions of HCN4 and Cx43 in the sinoatrial node were observed by immunohistochemical technology. RESULTS: HCN4 positive cells expressed in the cell membrane and cytoplasm of the sinoatrial node. Cx43 positive cells expressed in the cell membrane and cytoplasm of T cells and myocardial cells. The expression of HCN4 was significantly higher than that of the control group (P < 0.05) and the expression of Cx43 was significantly lower than that of the control group (P < 0.05). CONCLUSION The changes of HCN4 and Cx43 expressions in the sinoatrial node illustrate electric shock death might be related to the abnormalities of cardiac electrophysiology and conduction.

OBJECTIVEAfter sinboneHT bone replacement (SBR) was implanted in animals, to evaluate the biocompatibility of SBR and compounded in autogenetic bone in the proportion of one to one in order to prepare for the clinical applications in the future.

METHODSBone defects of 10 mm x l0 mm x 2 mm was made at the mandibular of rabbits, then SBR with different granule diameter and autogenetic bone was compounded in the proportion of being applied in the left defects, while autogenetic bone was implanted in the right defects and nothing was used in the right reformed defects. Animals were sacrificed at 2, 4 and 8 weeks respectively. The biologic capacity was evaluated with anatomy, X-rays studies and histology.

RESULTSSBR has better biocompatibility, which can effectively accelerate the reconstruction of bone defects and help the new bone by being compounded with autogenetic bone. It provides the appropriate scaffold or template which would allow cellular infiltration, attachment and multiplication.

CONCLUSIONSBR is a kind of bone substitute material with good biocompatibility. SBR compounded with self-bone has a better regeneration function.

Objective To investigate the application of the OSCE training on the intensive training of nursing skills for college students majoring in nursing in the fourth semester.Methods Students from 2013 undergraduate session were investigated.They were randomly divided into two groups. The experimental group (n = 134) was trained of the OSCE training, while the control group (n = 135) received of traditional training. After the training, analysis of test scores and questionnaires were used to survey the comments of the two groups of students on intensive training of nursing skills. After two months of practice, the clinical comprehensive ability of the students was evaluated by clinical teachers.Results The experimental group's theory and nursing skills were higher than those of the con－trol group (P＜0.01) . The experimental group had a positive attitude towards nursing OSCE training. Their famil－iarity with the operation skills, team cooperation spirits, presentation and communication ability, observation ability, clinical adaptation ability and health education ability were enhanced (P＜0.01).Conclusion The comprehen－sive simulation training cannot only improve the effectiveness of OSCE training, but also strengthen the students'clin－ical comprehensive ability and promote the practice quality.

OBJECTIVETo evaluate the late endothelial function in children with coronary aneurysm due to Kawasaki disease (KD).

METHODSThirty-one children with coronary aneurysms due to KD who had the disease course for more than 1 year and twenty-one age-matched healthy children were enrolled. Brachial artery endothelium-dependent and -independent flow-mediated dilation (FMD), carotid arterial stiffness index (SI) and intima-media thickness (IMT) were measured by high-frequency ultrasound.

RESULTSThere were 9 cases of medium and 22 cases of giant coronary aneurysms in the KD group. Twelve KD patients had evidence of myocardial ischemia. Compared to the normal controls, the endothelium-dependent FMD decreased (P<0.05), the carotid arterial SI increased (P<0.05), and the carotid arterial intima-media thickness increased significantly (P<0.05) in children with coronary aneurysms due to KD. The endothelium-dependent FMD decreased more significantly in 12 KD patients with myocardial ischemia than in those without any evidence of myocardial ischemia (P<0.05).

CONCLUSIONSLate endothelial dysfunction exists in children with coronary aneurysms due to KD, especially in those with myocardial ischemia.
