Objective To investigate the clinical effect of insulin on gestational diabetes mellitus(GDM).Methods GDM patients were randomly divided into group A and group B,group B were treated with short term intensive insulin pump therapy,and group A were treated with insulin pump in short term combined with biosynthetic human insulin therapy.Results The body mass index and diabetes family history rates pre-pregnancy in group B were significantly higher than group A(P<0.05).Logistic analysis showed that family history of BMI pre-pregnancy and diabetes family history were independent risk factors for GDM drug treatment(P<0.05).Compared with the group B,the improvement of blood glucose levels and the incidence of complications in patients with group A were better than the former(P<0.05).Conclusion Rational application of insulin can improve the efficacy of clinical treatment of GDM, reduce the incidence of complications, with high safety.

Objective To explore the difference of treating carpal tunnel syndrome (CTS) with needling Yangchi point and moxibustion on Yangchi point.Methods 38 cases of CTS were randomly recruited into a treatment group (19 cases) and a control group (19 cases).The treatment group was treated with electric acupuncture on Yangchi point and the control group was treated with moxibustion on Yangchi point.VAS (visual analogue scale) and GSS (overall symptom score table) scores were measured before and after the treatment.Results After the treatment VAS,GSS scores were (3.95± 1.87),(13.42±7.81) in the treatment group and (4.26±2.38),(14.63±9.97) in the control group,both decreased than those in the same group before the treatment [treatment group were (6.89± 1.56),(25.58±8.09) ; the control group were (5.79± 1.69),(20.37±8.67)],and the difference between the two groups was significant (t=-3.06,-3.39,P＜0.05).3 months follow-up after the treatment,the value of VAS and GSS scores in treatment group were (3.29±2.31)％ and (8.06±7.77); in the control group were (3.28±2.95) and (10.44±9.82),both decreased than those in the same group before the treatment [treatment group were (6.76± 1.56),(24.76±8.17); the control group were (5.78± 1.73),(20.33± 8.92) (P＜0.05)].The difference of VAS score was not significant between the two group (t=-1.49,P＞0.05); while the difference of GSS score showed statistical difference between the two groups (t=-2.64,P＜0.05).Conclusion Acupunctureon Yangchi point can effectively improve pain,numbness and motor activity in patients with the carpal tunnel syndrome.

Objective The pathogenesis of T2DM has not been elucidated.This study aimed to explore the association of FXR gene polymorphisms with the risk of T2DM in Eastern China population. Methods We collected 467 cases in the Health Examination Center of our hospital from January 2011 to December 2012.Ligase detection reaction was performed to test the genotypes in 240 T2DM patients and 227 controls.Unconditioned logistic regression analysis was used to explore the association of FXR gene polymorphisms with the risk of T2DM in different genetic models, after adjusting for age, sex, smoking and drinking status. Results Compared with AA genotype, GG significantly increased the risk of T2DM (P=0.017), while GA+GG approached marginal significance in association with T2DM (P=0.049) in rs1030454.For rs10860598, GA reduced the incidence of T2DM (P=0.025) compared with AA genotype, while GA+GG had marginal significance with T2DM (P=0.049).For rs11110411, CT or CT+CC could reduce the risk of T2DM compared with TT with P value of 0.016 and 0.024 respectively.Compared with AA, GA or GA+GG in rs17030270 was negative with the risk of T2DM with P value of 0.018 and 0.032 respectively. Conclusion FXR gene polymorphisms are associated with the risk of T2DM in northern Chinese Han population and the variation of FXR gene may play a role in the pathogenesis of T2DM.

Objective To investigate the possible association between vascular endothelial growth factor (VEGF), endostatin (ES) and type 2 diabetic nephropathy. Methods The level of serum VEGF and ES were measured by ELISA in eighty type 2 diabetic patients including thirty subjects without diabetic nephropathy , twenty with microalbuminuria and thirty with macroalbuminuria, and the correlation was analyzed. Results The level of serum VEGF and ES in patients with macroalbuminuria were both significantly higher than that of patients with and without microalbuminuria (P < 0.05). The level of serum VEGF and ES in patients with microalbuminuria were significantly higher than that of patients without diabetic nephropathy (P<0.05). Both VEGF and ES level were positively correlated with the level of microalbuminuria (mAlb) (r=0.226, P<0.01; r=0.491, P<0.01), and negatively correlated with the level of estimated glomerular filtration rate (eGFR) (r=-0.237, P<0.05;r=-0.620, P<0.01). There was a significantly positive correlation between VEGF and ES in patients with microalbuminuria and macroalbuminuria (r1=0.633, P1<0.01; r2=0.532, P2<0.05). However, there was no correlation between VEGF and ES in patients without diabetic nephropathy (r3=0.175, P3>0.05). Conclusion The levels of VEGF and ES in type 2 diabetic nephropathy had varying degree of increasing in different diabetic nephropathy stage , and closely related to mAlb and eGFR. Disequilibrium of VEGF and ES may speed up the progression of diabetic nephropathy.
