Objective To investigate the potential contributing effects of metabolic syndrome (MS) on cardiovascular events and mortality in maintenance hemodialysis (MHD) patients.Methods According to the diagnostic criteria for MS set by Chinese Diabetes Society,201 subjects undergoing MHD were assigned into MS group(n =78) or non-MS group (n =123),in August 2009.General and laboratory data were collected for cross-sectional analyses,and the participants were followed up for 36 months.Cardiovascular events,cause of death and time were recorded for longitudinal analyses.Results Prevalence of MS was 38.8％.Weight,waist circumference,triglyceride,total cholesterol,low density lipoprotein,fasting glucose level,uric acid and high-sensitivity C-reactive protein were significant higher in MS group compared to non-MS group,but duration of dialysis and high-density lipoprotein were lower (P ＜ 0.05).During the 36 months follow-up,cumulative incidence of cardiovascular events,cardiovascular and all-cause mortality were 41.0％ (32/78),19.2％ (15/78),28.2％ (22/78),in MS group respectively.Those of non-MS group were 22.8％ (28/123),10.6％ (13/123),17.1％ (21/123).There was significant difference between patients with and without MS in cumulative incidence of cardiovascular events (x2 =7.601,P =0.006).There was relationship between the number of metabolic syndrome parameters and cardiovascular events (r =0.236,P =0.001).Kaplan-Meier curves showed the relationship between two groups did not remained statistically significant in cardiovascular and all-cause mortality.Impaired glycometabolism in 5 parameters of MS was a cardiovascular mortality risk factor in MHD patients.Conclusions The prevalence of MS is high in MHD patients.MS is a risk factor of cardiovascular events,but it is not associated with cardiovascular and all-cause 3-year mortality in patients with MHD.

Objective To investigate the potential correlation between serum magnesium and malnutrition-inflammation-atherosclerosis (MIA) syndrome in maintenance hemodialysis (MHD) patients.Methods A total of 120 patients who received MHD in Department of Blood Purification of Beijing Chaoyang Hospital from March to August 2013 were enrolled.Anthropometric and laboratory data were collected for the analysis of correlation between serum magnesium and indicators relating to malnutrition,chronic inflammation,and atherosclerosis,and the analysis of relevant factors of MIA syndrome.Results In the 120 MHD patients,the mean serum magnesium level was (1.11 ±0.14) mmol/L.44 patients had malnutrition (36.7％),whose serum magnesium level was significantly lower than that of patients in normal nutritious status [(1.04 ±0.12) mmol/L vs.(1.14 ±0.15) mmol/L,t =3.576,P =0.001] ; 43 patients had chronic inflammation (35.8％),with serum magnesium level significantly lower than that of patients without inflammation [(1.07 ±0.13) mmol/L vs.(1.13 ±0.15) mmol/L,t =2.138,P =0.035]; 79 patients had atherosclerosis (65.8％),whose serum magnesium level was significantly lower than that of patients without atherosclerosis [(1.08 ±0.12) mmol/L vs.(1.15 ±0.08) mmol/L,t =0.385,P =0.019] ; and 26 patients had MIA syndrome (21.7％),whose serum magnesium level was significantly lower than that of non-MIA patients [(1.02 ± 0.10) mmol/L vs.(1.13 ± 0.14) mmol/L,t =3.534,P =0.001].Serum magnesium level was found negatively correlated with high-sensitivity C-reactive protein (hs-CRP,r =-0.237,P =0.010) and carotid intima-media thickness (IMT,r =-0.331,P =0.000),and positively correlated with serum albumin,blood urea nitrogen,serum creatinine,uric acid,serum potassium,triceps skin-fold thickness,mid-arm circumference,mid-arm muscle circumference and hemoglobin (r =0.191,P =0.037; r =0.345,P =0.000; r =0.242,P=0.008; r =0.282,P=0.002; r=0.254,P=0.005; r=0.265,P=0.011; r=0.233,P=0.018; r=0.282,P=0.007; r=0.374,P =0.000).Multivariate logistic regression analysis showed that age (OR =1.142,95％ CI =1.026-1.271,P=0.049),hs-CRP (OR=1.415,95％ CI=1.152-1.740,P=0.001),IMT (OR =1.386,95％ CI=1.009-1.904,P=0.044),serum albumin (OR =0.944,95％ CI=0.910-0.978,P=0.002) and serum magnesium (OR =0.886,95％ CI =0.788-0.996,P =0.042) were related factors of MIA syndrome.Conclusions Serum magnesium level is correlated to malnutrition,inflammation,atherosclerosis,and MIA syndrome in MHD patients.

Objective To investigate the potential contributing effects of fasting plasma glucose on cardiovascular events in diabetic patients treated with maintenance hemodialysis.Methods According to fasting plasma glucose,154 patients undergoing maintenance hemodialvsis in our department were assigned into group A (n =84) nondiabetic with normal fasting blood glucose,group B (n =41) diabetic with good control of fasting blood glucose,and group C (n =29) diabetic with poor control of fasting glucose.Anthropometric and laboratory data were collected,and the participants were followed up for 36 months.Cardiovascular events and hypoglycemia were recorded and analyzed.Results Highly-sensitive C reactive protein (hs-CRP),triglyceride,and waist circumference were significantly higher in group B and group C compared with group A.Bodv mass index in group C was the highest while high density lipoprotein-cholesterol and intact parathyroid hormone levels were the lowest among 3 groups (P＜0.05).During the 36 months follow-up,47 cases of cardiovascular events occurred.Kaplan-Meier curves showed that cumulative incidence of cardiovascular events was significantly higher in group C than group A and B (both P＜0.01),and no significant difference was found between group A and B.Cox regressive analysis revealed that fasting plasma glucose and hs-CRP were independant risk factors for cumulative incidence of cardiovascular events (P＜0.05 or P＜0.0l).Conclusions If fasting plasma glucose is contmlled within the range of 5.6 to 7.2 mmol/L,cardiovascular outcomes may be significantly ameliorated in diabetic patients treated with maintenance hemodialysis.

Objective To explore the relationship between total bile acid(TBA)concentration and fetal pulmonary surfactant in intrahepatic cholestasis of pregnancy(ICP).Methods Fifry five patients with ICP(ICP group)who received cesarean section from April 2008 to February 2010 in Second Xiangya Hospital,Central South University,were recruited.The general conditions of the neonates within 7 days after birth in ICP group were recorded.Those with fetal distress,neonatal asphyxia,or neonatal respiratory distress syndrome were referred as pathological neonates, others were referred as normal neonates. Over the same period, 23 healthy gravidas were recruited as control group. Enzymatic method was used to detect the TBA concentrations in maternal blood, cord blood and amniotic fluid. ELISA was employed to measure the urfactant protein A (SP-A) concentration in cord blood. High performance liquid chromatography system was used to detect the concentrations of phesphatidylcholine (PC),phosphatidylinositol (PI),lysophosphatidylcholine ( LPC), and sphingomyelin(SM) in amniotic fluid. Results ( 1 ) The concentrations of TBA in maternal blood, cord blood and amniotic fluid were ( 30. 1 ± 7.9 ), (9. 3± 3. 3 ) and (4. 4 ± 1.5 ) mmol/L in ICP group, (4. 8 ± 2. 2), (4. 9 ± 0. 9) and ( 1.4 v 1.1 ) mmol/L in control group, respectively. The differences between the two groups were significant ( P ＜ 0. 05 ). ( 2 ) The SP-A concentration in cord blood in ICP group was ( 29. 5 ± 6. 4 ) μg/L, significantly higher than that in control group, which was ( 22. 6 ± 7. 4 )μg/L ( P＜ 0. 05 ). ( 3 ) There were 20 pathological neonates and 35 normal neonates in ICP group. In pathological neonates, the concentrations of TBA and SP-A in cord blood were (10.9 ± 2.2) mmol/L,(37.0 ± 5.9 ) μg/L, respectively; and were ( 8.0 ± 2. 8 ) mmol/L, ( 26. 7 ± 4. 8 ) μg/L in normal neonates. The differences were significant (P＜ 0. 05 ). (4) There was a positive correlation between TBA concentration in cord blood and in maternal blood ( r1 = 0. 706, P＜0. 05 ). The TBA concentration in cord blood was positively correlated with SP-A concentration as well ( r3 = 0. 494,P ＜ 0. 05 ). (5) The PC and PI concentrations in amniotic fluid were (65.4 ± 7.2) mg/L and ( 3. 8 ± 0. 6 ) mg/L in ICP group, ( 69. 7 ±3.7) mg/L and (4. 3 ± 0. 7 ) mg/L in control group, respectively. The differences were significant (P ＜0. 05 ). The concentration of LPC in amniotic fluid in ICP group was (4. 8 ±0. 9) mg/L, significantly higher than that in control group (P＜0. 05), which was (4. 2 ±0. 6) mg/L. The concentration of SM in amniotic fluid was (3.5±0. 8) mg/L in ICP group, (4. 0 ± 0. 5 ) mg/L in control group, with no significant difference ( P＞0. 05 ). (6) The ratio of PC/LPC in ICP group ( 14. 2± 3. 2 ) was significantly lower than that in control group ( 16. 9 ± 2. 5 ) ( P＜ 0. 05 ). ( 7 ) The TBA concentration in cord blood was negatively correlated with PC and PI concentrations (r1 = -0. 561, r2 = -0. 407, P ＜ 0. 05 ), and had no correlation with LPC concentration (r3 = 0. 260, P＞ 0. 05). Conclusions ( 1 ) The fetal TBA concentrations in both cord blood and amniotic fluid of patients with ICP was higher than those of healthy gravidas, they were also positively correlated with maternal TBA concentration. (2) ICP resulted in the change of fetal pulmonary surfactant and this change was associated with TBA concentrations in both cord blood and amniotic fluid.
