ObjectiveTo investigate whether single nucleotide polymorphism (SNP) of macrophage migration inhibitory factor (MIF) gene - 173G/C is associated with severe preeclampsia.Methods Totally 124 severe preeclampsia patients and 160 healthy pregnant women (control group) were included in our study who were recruited consecutively from Affiliated Hospital of Qiugdao University Medical College between March 2010 and March 2011.The SNP was detected through SYBR Green PCR.The levels of fasting blood glucose ( FBG),fasting insulin ( FIN),and serum total cholesterol (TC),triglyceride ( TG),high density lipoprotein (HDL) and light density lipoprotein (LDL) were determined in every participants.The homeostasis model assessment-insulin resistance (HOMA-IR) was calculated.The allele and genotype frequencies between severe preeclampsia patients and control group were compared.The FBG,FIN,body mass index (BMI),HOMA-IR,TC,TG,HDL and LDL in different genotype were compared.Results ( 1 ) The MIF - 173G/C SNP genotype frequencies of GG,CG,and CC were 62.1％ (77/124),30.6％ (38/124),7.3％ (9/124),the allelic frequencies of G and C were 77.4％ ( 192/248 ) and 22.6％ (56/248),respectively,in severe preeclampsia patients; the MIF - 173G/C SNP genotype frequencies of GG,CG,and CC were 64.4％ ( 103/160 ),30.6％ (49/160),5.0％ ( 8/160),the allelic frequencies of G and C were 79.7％ (255/320) and 20.3％ (65/320),respectively,in the control group.No significant differences were observed in the genotypes and allele distributions of MIF - 173G/C SNP between the severe preeclampsia patients and control group (all P ＞ 0.05 ).(2) The severe preeclampsia patients with CG and CC genotypes had higher BMI compared with the GG genotype [ (25 ±4) versus (22 ±4) kg/m2 ; t =3.96,P ＜ 0.05 ].( 3 ) The severe preeclampsia patients with CG and CC genotypes had higher FIN level and higher HOMA-IR compared with the GG genotype [ ( 15.7 ±2.9) versus ( 13.6 ±4.0) mmoL/L,3.3 ±0.5 versus 2.7 ± 0.6 ; t =3.17,t =5.58,all P ＜ 0.05 ].(4) There was no significant difference in FBG,TC,TG,HDL and LDL levels in severe preeclampsia patients with different genotypes (all P ＞0.05 ).Conclusions The present study suggests that the MIF - 173G/C SNP is associated with insulin resistance in severe preeclampsia patients.The CG and CC genotypes increase the degree of insulin resistance,but it is may not associate with susceptibility among severe preeclampsia patients of Han Chinese women.

Objective To investigate the variance levels of plasma soluble leukocyte differentiation antigens CD40 (sCD40) and soluble CD40 ligand (sCD40L) in preeclamptic patients with renal damage and its relationship. Methods A total of 63 pregnant women attended the Department of Obstetrics, Affiliated Hospital of Qingdao University Medical College between August 2008 and June 2010. In the present study included 28 pregnant women with mild preeclampsia and 35 patients with severe preeclampsia. Thirty matched normotensive pregnant women were enrolled in the study as the control group. Expression of sCD40 and sCD40L were determined by ELISA. At the same time, the blood routine, C reaction protein ( CRP),urine routine, 24 hours urine protein excretion, and serum uric acid (UA), creatinine (Cr), blood urea nitrogen (BUN) were measured. The correlation analysis was performed between the sCD40/sCD40L and the blood biochemical indexes in 3 groups. Results ( 1 ) The median levels of CRP in severe preeclampsia (10. 8 mg/L)and mild preeclampsia group(7. I mg/L)are significantly higher than that of control group (3. 3 mg/L,P ＜ 0. 05 ); The level of CRP in severe preeclampsia group was also higher than that of mild preeclampsia group ( P ＜ 0. 05 ). The median gestational age at delivery in severe preeclampsia ( 32. 5 weeks)was significantly less than that of mild preeclampsia group ( 37. 2 weeks) and normal group ( 38. 6 weeks,P ＜ 0. 05). However no significant differences were observed between mild preeclampsia group and normal group ( P ＞0. 05 ). The platelet count in severe preeclampsia ( 132 × 109/L) was significantly less than those of mild preeclampsia group (212 × 109/L) and normal group ( 216 × 109/L, P ＜ 0. 01 ), but no significant differences were observed in blood platelet amount between mild preeclampsia group and normal group ( P ＞0. 05 ). There was no significant difference in hemoglobin level and white blood cell in three groups ( P ＞0. 05). (2) The sCD40 plasma concentration in severe, mild preeclampsia and normal group was 133.6,126. 5 and 90. 7 ng/L, respectively. The sCD40 L plasma concentrations were 12. 5, 10. 4 and 4. 4 ng/L respectively in the 3 groups. 24 hours urinary protein quantitative was 4. 5 g/d,0. 8 g/d and 0 in the 3 groups respectively. And the UA level was 486 μ mol/L,289 μmol/L and 162 μmol/L. In the above three groups,the monitoring indicators were significantly higher in women with severe preeclampsia group compared with mild preeclampsia and control groups (P ＜ 0. 01 ), and there were also higher in mild preeclampsia group than that in control groups ( P ＜ 0. 01 ). The level of plasma Cr ( 89 μmol/L) and BUN ( 5. 32 mmol/L) in severe preeclampsia group were higher than those of mild preeclampsia group (66 μmol/L and 4. 49mmol/L) and control group ( 57 μmol/L and 3.32 mmol/L, P ＜ 0. 05 ). There was no significant difference between mild preeclampsia group and normal group (P ＞ 0. 05 ). (3) The correlation analysis indicated that the level of sCD40 has a positive correlation with 24 hours urinary protein quantitative( r = 0. 434, P ＜ 0. 05 ),also significant positive correlation( r =0. 536,0. 528 ,P ＜ 0. 01 ) between the level of sCD40 and UA or CRP in women with preeclampsia. There was no significant correlation between the level of sCD40 and systolic blood pressure, diastolic blood pressure, delivery gestational age, Cr, BUN, and platelet count(r =0. 135,0. 183, -0. 133,0. 190,0. 167, -0. 221 ,all P ＞0. 05 ). There were positive correlation between the level of sCD40L and 24 hours urine protein excretion, either UA or CRP( r =0. 591,0. 445,0. 539 ,all P ＜0. 01 ). No significant correlation was found between sCD40 L and systolic blood pressure, diastolic blood pressure,delivery gestational age, Cr, BUN, and platelet count( r =0. 178,0. 212, -0. 292,0. 144,0. 135, -0. 273,all P ＞0. 05). There was significant positive correlation between plasma sCD40 and sCD40L ( r =0. 707 ,P ＜0. 01 ). There was no relationship between the level of sCD40, sCD40L and the blood biochemical indexes in normotensive pregnant women ( P ＞ 0. 05 ). Conclusions The plasma concentrations of sCD40 and sCD40 L are significantly higher in pregnant women with preeclampsia compared with the control, which may be involved in the development of preeclampsia and contribute to the kidney damage. The variance levels of sCD40 and sCD40L may be also related to the severity of preeclampsia.

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 expression of macrophage migration inhibitory factor (MIF) and CD_(74), the receptor of MIF, in preeclamptic placenta and its correlation with the pathogenesis of preeclampsia.Methods From March 2008 to November 2008,69 preeclamptic women who delivered in the Department of Obstetrics, Affiliated Hospital of Qingdao University Medical College,were recruited,including 33 women with mild preeclampsia (MPE group) and 36 women with severe preeclampsia (SPE group).Another 43 healthy pregnant women were taken as control group.Immunoturbidimetry was applied to measure the concentrations of C-reactive protein (CRP) in maternal blood.The expressions of MIF and CD_(74) in placenta were tested with immunohistochemistry and the expressions of MIF mRNA and CD_(74) mRNA were detected by semiquantitative RT-PCR.The relationship between maternal blood level of CRP and MIF mRNA and CD_(74) mRNA in placenta was analyzed in the MPE and SPE group.Results (1) MIF and CD_(74) were expressed in the placenta of all pregnant women in the 3 groups, as shown in brown-yellow color, and significantly higher expression was found in the MPE and SPE group.(2) The expression of MIF mRNA and CD_(74) mRNA in the MPE group (0.70±0.13 and 0.96±0.16), SPE group (0.88 ± 0.12 and 1.08 ± 0.15) were significantly higher than in the control group (0.67 ± 0.11 and 0.83 ± 0.14) (P < 0.01), and statistical significance was also found between the MPE and SPE group (P <0.01).(3)The maternal blood concentrations of CRP in the MPE and SPE group were significantly higher than in the control group [(15.3±7.0) mg/L and (21.6±9.1)mg/L vs (4.8 ± 1.8) mg/L, P <0.01] , and significant difference was also found between the MPE and SPE group (P <0.01).(4) In the two preeclamptic groups, the blood concentrations of CRP were positively correlated with the expression of both MIF mRNA(r =0.67 ,P <0.01)and CD_(74) mRNA(r =0.83 ,P <0.01) in placenta.Positive correlation was also found between the levels of MIF mRNA and CD_(74) mRNA in placenta (r =0.93 ,P < 0.01).Conclusions Overexpression of MIF and CD_(74) in the placenta may up-regulate the CRP level in maternal blood, resulting in systemic inflammatory reaction and vascular endothelium damage which may be involved in the pathogenesis of preeclampsia.

Transverse fracture is the most common in patella fracture and tension band fixation is one of the most effective methods. Surgical wire tension band technique is simple, the use of materials is also simple, but it is not strong and difficult to promote. Kirschner tension band technique can get satisfactory reduction with reliable fixation, but it is easy to complicate with steel wire breakage and Kirschner loosening. Screw tension band technique inherits the traditional advantages of simple manipulation and reliable fixation, also overcomes the disadvantages of early activity limitations caused soft tissue irritation of tension band around knee, the slippage and breakage of internal fixation, and the technique can be popularized generally.
