Purpose to understand the hospitalized prevalence of diabetes mellitus (DM) in patients with peripheral neuropathy (DPN). 2, the analysis of the risk factors of DPN. 3, analysis of microvascular complications of DM DPN. 4, to understand the ankle-brachial index (ABI) with DPN and ABI, the diagnostic value of the DPN and lower extremity arterial disease (PAD). Methods Affiliated Hospital of Ningxia Medical University, April 2009 - November 2009 in the Department of Endocrinology, Hospital treatment of type 2 diabetes mellitus (T2DM) patients with 192 cases for the study, based on sensory nerve conduction velocity (SCV) or / and motor nerve conduction The abnormal velocity (MCV) were divided into 124 cases of type 2 diabetes with peripheral neuropathy group (DPN group) and 68 cases of non-merger peripheral neuropathy group (no DPN group). General Information collected two groups of patients and laboratory parameters. Influencing factors and DPN relationship univariate analysis, the measurement data to x ± s that the groups were compared by t test, sample rate x2 test. In order to control the mutual interference between the factors, based on single-factor analysis of the results, select the statistically significant chi-square value is close to the risk factors of significant boundaries, into the logistic regression model for non-conditional multivariate analysis to reflect the risk of factors and the correlation of DPN. And different cut-off point of the ABI group, the incidence of each group of DPN x2 test. 1,192 subjects were male 100 cases, female 92 cases, aged 33 to 78 years old, the average age of 57.85 ± 11.252 the disease duration lt; 5 years 40 cases, duration of ≥ 5 years 152 cases, the average duration of 9.58 ± 7.065 years. According to the neurophysiological examination the DPN group of 124 patients, the detection rate of 64.58% (124/192), male DPN 72 cases, accounting for 72% (72/100), women DPN 52 cases, accounting for 56.52% (52/92 ) in men than women. DNP group with no the DPN group of single-factor comparison the DPN group of age, duration of fasting blood glucose (FBG), 2h postprandial blood glucose (2hBPG), glycosylated hemoglobin (HbA1c), triglycerides (TG), total cholesterol (TC ), blood urea nitrogen (BUN) and urinary albumin (MA) were increased, the differences were statistically significant (P lt; 0.05); high-density lipoprotein cholesterol (HDL-C), total bilirubin (TBIL ), direct bilirubin (DBIL) and indirect bilirubin (NDBIL) DPN group were lower than the DPN group; BMI, low-density lipoprotein cholesterol (LDL-C) and combined systolic blood pressure, diastolic blood pressure in the two between the two groups was not statistically significant; the DPN combination and ratio of coronary heart disease than those without DPN group, a statistically significant difference. The subjects were divided according to duration of disease lt; 5 years, 5 to 9 years 10 to 19 years, ≥ 20 years, the statistical analysis shows ≥ 5 years duration each group DPN detection rate was significantly increased several times over, ≥ 20 years duration, the DPN detection rate of 100%. HbA1c gt; 6.5% group DPN detection rate was significantly higher than HbA1c ≤ 6.5% group. ABI value of the DPN group was significantly lower than the DPN group. 3, the object of study to ABI ≤ 0.9 and ABI GT; 0.9 is divided into two groups ABI ≤ 0.9 DPN detection rate of 90%, ABI gt; 0.9 of DPN detection rate of 57.89%, X2 test, P lt; 0.01 DPN detected between the two groups was statistically significant. The the DPN group with DPN group was statistically significant incidence of diabetic nephropathy (DN) and diabetic retinopathy (DR). DPN as dependent variables, different indicators as independent variables in univariate analysis, multivariate Logistic multiple regression analysis, the results show that the course of the disease, HbA1c, TG, DN, DR and PAD (ABI ≤ 0.9) for the risk of DPN factors, HDL-C and NDBIL DPN protective factors. Conclusion In this study, EMG diagnosis of DPN, the detection rate of 64.58%. Tip: to raise awareness of DM patients with DPN early screening for early prevention as a diabetes specialist. 2, the study was conducted the Multivariate Logistic multiple regression analysis, the results show that the course of the disease, HbA1c, TG, DN, DR and PAD (ABI ≤ 0.9) DPN risk factors, HDL-C and NDBIL DPN protective factors. 3, lower ankle-brachial index (ABI ≤ 0.9) up to 90% of diabetic peripheral neuropathy screening reliability, it is a sensitive indicator of early clinical screening; peripheral neuropathy and vascular lesions. 4, nerve conduction velocity testing is an effective means of early detection of peripheral neuropathy. Screening stage of the examination of the ankle-brachial index as a routine examination.
