Changes of serum ferritin and 25-(OH) vitamin D3 in cranial neuropathy diabetic patients / 中国医师杂志

Objective To observe the changes of serum ferritin and 25-(OH) vitamin D3 in patients with diabetic cranial neuropathy.Methods There were 50 patients without diabetic Cranial neuropathy,46 patients with diabetic cranial neuropathy,and 40 cases of normal control group.The changes of serum ferritin and 25-hydroxy vitamin D3 were observed in each group.The correlation between two indexes and the correlation with diabetic cranial neuropathy were analzyzed.Results The serum ferritin levels in diabetic group and diabetic neuropathy group were significantly higher than those in normal control group (P ＜ 0.01),and its level in patients with diabetic cranial neuropathy [(687.54 ± 65.38)ng/ml] was significantly higher than that of patients without diabetic cranial neuropathy [(497.28 ± 46.39) ng/ml,P ＜0.01].The serum 25-(OH) vitamin D3 levels in the diabetic group and diabetic neuropathy group were lower than those in the control group (P ＜ 0.01),and its level in patients with diabetic cranial neuropathy [(26.45 ± 8.93)nmol/l] was significantly less than that of patients without diabetic cranial neuropathy [(37.19-± 9.74)nmol/L,P ＜ 0.01].Serum ferritin levels were positively correlated with 25-(OH) vitamin D3 (r =-0.59,P ＜ 0.01).Multivariate unconditional Logistic regression analysis showed that diabetic neuropathy was negatively correlated with 25-(OH) vitamin D3 (P ＜ 0.05).Conclusions The increases of serum ferritin and 25-(OH) vitamin D3 are closely related to the occurrence and development of diabetic cranial neuropathy,which provides the theoretical basis for clinical intervention therapy.

Effect of early-stage keep warm intervention on improving low temperature risk in children underwent blood purification treatment / 中国实用护理杂志

Objective To evaluate the clinical effectiveness of early-stage keep warm intervention on improving low temperature risk children treated with blood purification (BP). Methods Ninety children were randomized into observation group (46 cases) and control group of (44 cases) from July 2013 to September 2015. Control group were nursed with conventional BP standard operation process, while the observation group were nursed additionally with heat insulation blanket before 30 min of booting machine, and recorded the central body temperature of 0 min,30 min,60 min,90 min,120 min for each 60 min 1 time in the future. Until the end of the blood purification 60 min. Low temperature complications were recorded and judged between the two groups. Results In the observation group, 107 cases of low body temperature occurred during the course of 7 cases of blood purification, occurrence rate of 6.5% (7/107). The control group was 15.8% (16/101). The difference between the 2 groups was statistically significant (χ2=4.569,P<0.05);In the continuous blood purification group, observation group 10.6% (5/47), The incidence rate of control group was 29.3% (12/41), he difference between the 2 groups was statistically significant (χ2=4.876,P<0.05). Conclusions Application of heat insulation blanket at the early-stage may effectively reduce the risk of hypothermia complications in the children treated with blood purification. The continuous blood purification effect is more significant.

Relationship between the levels of homocysteine and adiponectin in patients with type 2 diabetes mellitus / 中国基层医药

Objective To investigate the relationship between serum levels of homocysteine (HCy) and adiponectin (APN) in patients with type 2 diabetes mellitus(T2DM).Methods 65 patients with T2DM (diabetes mellitus group) and 25 healthy controls (control group) matched in the age and sex were recruited in the study.Serum HCy,APN,fasting plasma glucose (FPG),fasting insulin (FINS),total cholesterol (TC) and triglyceride (TG) were simultaneously measured.The homeostatic model assessment for insulin resistance(HOMA-IR) was calculated according to FPG and FINS.All the serum indicators were compared between the two groups.Results Serum level of HCy in T2DM group was (15.74 ± 2.76) μmol/L,which was significantly higher than (6.98 ± 1.94) μmol/L in the healthy control group (t =16.88,P ＜ 0.01).The serum level of APN in T2DM group was (8.14 ± 2.70) mg/L,which was significantly lower than (16.10 ± 1.93)mg/L in the healthy control group (t =13.44,P ＜ 0.01).Serum levels of FPG,HOMA-IR,TC,TG in T2DM group were significantly higher than those in the healthy control group (t =10.62,17.49,6.30,7.52,P ＜ 0.05).Serum level of APN in HCy ≥ 15μmol/L group was significantly decreased compared with HCy ＜ 15μmol/L group.Serum level of HCy was negatively correlated with APN in T2DM group after the influence of FPG,HOMA-IR,TG,TC were corrected in the partial correlation analysis.Conclusion In T2DM group,serum level of HCy was increased,but serum level of APN was decreased,serum HCy was negatively correlated with APN,higher serum level of HCy and lower serum level of APN are related with the process of insulin resistance and T2DM.
