Background: Comprehensive management of diabetes should include management of its comorbid conditions, especially cardiovascular complications, which are the leading cause of morbidity and mortality among patients with diabetes. Dyslipidemia is a comorbid condition of diabetes and a risk factor for cardiovascular complications. Therefore, lipid level management is a key of managing patients with diabetes successfully. However, it is not clear that how well dyslipidemia is managed in patients with diabetes in local Chinese health-care communities. This study aimed to assess how well low-density lipoprotein cholesterol (LDL-C) was managed in Nanjing community hospitals, China., Methods: We reviewed clinical records of 7364 diabetic patients who were treated in eleven community hospitals in Nanjing from October 2005 to October 2014. Information regarding LDL-C level, cardiovascular risk factors, and use of lipid-lowering agents were collected., Results: In patients without history of cardiovascular disease (CVD), 92.1% had one or more CVD risk factors, and the most common CVD risk factor was dyslipidemia. The overall average LDL-C level was 2.80 ± 0.88 mmol/L, which was 2.62 ± 0.90 mmol/L and 2.82 ± 0.87 mmol/L in patients with and without CVD history respectively. Only 38% of all patients met the target goal and 37.3% of patients who took lipid-lowering agents met target goal. Overall, 24.5% of all patients were on lipid-lowering medication, and 36.3% of patients with a CVD history and 20.9% of patients without CVD history took statins for LDL-C management. The mean statin dosage was 13.9 ± 8.9 mg., Conclusions: Only a small portion of patients achieved target LDL-C level, and the rate of using statins to control LDL-C was low. Managing LDL-C with statins in patients with diabetes should be promoted, especially in patients without a CVD history and with one or more CVD risk factors.

Background: To determine the frequency of chronic kidney disease (CKD) and its associated risk factors in Chinese type 2 diabetic patients, we conducted a cross-sectional study in Nanjing, China, in the period between January 2008 and December 2009., Methods: Patients with type 2 diabetes under the care by Jiangsu Province Official Hospital, Nanjing, China were invited for assessment. CKD was defined as the presence of albuminuria or estimated glomerular filtration rate <60 mL/min/1.73 m(2). Albuminuria was defined as urinary albumin-to-creatinine ratio ≥30 mg/g., Results: We recruited 1,521 urban Chinese patients with type 2 diabetes (mean age, 63.9±12.0 years). The frequency of CKD and albuminuria was 31.0% and 28.9%, respectively. After adjusted by age and sex, hypertension, anemia and duration of diabetes were significantly associated with CKD with odds ratio (95% confidence interval) being 1.93 (1.28 to 2.93), 1.70 (1.09 to 2.64), and 1.03 (1.00 to 1.06), respectively., Conclusion: In conclusion, CKD was common in the urban Nanjing Chinese with type 2 diabetes. Strategies to prevent or delay progression of kidney disease in diabetes should be carried out at the early disease course of type 2 diabetes.

Background/aims: The application of glycated hemoglobin (HbA(1c)) for the diagnosis of diabetes is currently under extensive discussion. In this study, we explored the validity of using HbA(1c) as a screening and diagnostic test in Chinese subjects recruited in Nanjing, China., Methods: In total, 497 subjects (361 men and 136 women) with fasting plasma glucose (PG) ≥ 5.6 mmol/L were recruited to undergo the oral glucose tolerance test (OGTT) and HbA(1c) test. Plasma lipid, uric acid, and blood pressure were also measured., Results: Using a receiver operating characteristic curve, the optimal cutoff point of HbA(1c) related to diabetes diagnosed by the OGTT was 6.3%, with a sensitivity and specificity of 79.6% and 82.2%, respectively, and the area under the curve was 0.87 (95% confidence interval, 0.83 to 0.92). A HbA(1c) level of 6.5% had a sensitivity and specificity of 62.7% and 93.5%, respectively. When comparing the HbA(1c) ≥ 6.5% or OGTT methods for diagnosing diabetes, the former group had significantly higher HbA(1c) levels and lower levels of fasting and 2-hour PG than the latter group. No significant difference was observed in the other metabolism indexes between the two groups., Conclusions: Our results suggest that HbA(1c) ≥ 6.5% has reasonably good specificity for diagnosing diabetes in Chinese subjects, which is in concordance with the American Diabetes Association recommendations.

Background and Study Aims: Delayed gastric emptying (DGE) is the commonest gastrointestinal (GI) complication in type 2 diabetes. We aimed to evaluate the association between DGE and cardiovascular autonomic neuropathy (CAN) in type 2 diabetes., Patients and Methods: A total of 71 Chinese patients (39 men and 32 women, aged 60-90 years) and 30 controls (12 men and 18 women, aged 50-79 years) were studied in Nanjing, China. The gastric emptying was assessed by 13C-octanoic acid breath test (OBT) and gastric emptying ultrasonography (GEU). Cardiovascular autonomic neuropathy (CAN) was assessed by a scoring system being validated before., Results: The diabetic patients, except for a higher plasma glucose level, had similar characteristics compared to the non-diabetic controls. Diabetic patients had higher incidence of DGE and CAN than controls (48.5% vs. 10.7%, p = 0.001). Among diabetic patients with DGE (n = 27), 18 (66.7%) had CAN and 9 (33.3%) did not. Corresponding figures for those without DGE (n = 39) were 14 (35.9%) and 25 (64.1%), respectively (p = 0.014). Diabetes was independently associated with the risk of DGE with odd ratio (95% CI) of 15.6 (1.92, 127.06) (p = 0.010). The presence of diabetes or CAN was independently associated with the half gastric emptying time after adjusting for age, gender, plasma glucose and blood pressure., Conclusions: We found a much prolonged gastric emptying time in Chinese patients with type 2 diabetes as compared to non-diabetic controls. There was a high rate of CAN in diabetic patients, and it was associated with gastric emptying.

The aim of present study is to translate and validate a Chinese version of the WIQ in patients with PAD and T2DM. A cross-sectional survey was conducted. After translation, a convenience sample of 59 patients with PAD and T2DM completed the Chinese WIQ, the Chinese SF-36 and the 6MWT. The ICC and Cronbach's alpha were calculated to determine the reliability and internal consistency, respectively.Validity was evaluated by correlation coefficients between WIQ, SF-36 and 6MWD. The internal consistency determined by Cronbach's alpha was 0.93. Test-retest reliability expressed by ICC was 0.93. Significant correlations were observed between WIQ, SF-36 and 6MWD (ρ (s) =0.27 ∼0.88, p < 0.01).The Chinese version of the WIQ has satisfactory reliability and validity and can be used to assess walking ability in type 2 diabetic PAD patients.

Objective: To investigate the differences on the diabetic foot problems and its risk factors in south and north of China., Methods: Patients with foot problems were surveyed from January 1 to December 31, 2004 in 14 teaching hospitals located in different cities in China, including demographic data, present and past history of the foot problems and peripheral artery disease (PAD), the classification of the foot ulcers based on the Wagner' system, control of the hyperglycemia and lipids disorder, medical cost in hospital and the diabetic complications. All the patients were divided into two groups due to their geographical data, south and north., Results: There were 285 and 349 patients for the group south and group north. No significant differences were found for duration of diabetes or foot problems, fasting or post-meal glucose, total cholesterol, triglycerides, HDL-C, and the numbers of patients with smoke, hypertension, nephropathy or neuropathy between the two groups. There were significant differences for the age (70 yrs vs 66 yrs), percentage of the patients with average person income with over RMB 1000 per month (57.7% vs 45.6%), coronary heart disease (42.6% vs 61.0%) and retinopathy (35.7% vs 49.5%), HbA1c (7.90% vs 8.80 %), LDL-C (2.75 mmol/L vs 2.98 mmol/L), WBC (6.70 x 10(9) vs 7.40 x 10(9)/L), HCT (0.37 vs 0.38), creatinine (87 micromol/L vs 76 micromol/L) and uric acid (333 mmol/L vs 271 mmol/L), and amputation rate (2.6% vs 9.7%) between south and north groups. Logistic analysis showed that severity of the foot problems was associated with ABI and WBC in south group, and with ABI, PLT and HCT in north group., Conclusion: Diabetic foot problems were more severe, with more risk factors and with more medical cost in north patients.

Objective: To investigate the characteristics of diabetic foot with neuropathy and its related factors., Methods: 530 out- and in-patients in 14 grade A class 3 comprehensive hospitals in China with foot problems were surveyed. 337 of the 500 patients (63.58%) suffered from neuropathy, 172 (32.45%) with diabetic foot with simple neuropathy and 165 (31.13%) with simple neuropathy combined with peripheral artery disease (PAD). 193 of the 500 patients (36.42%) suffered from peripheral artery disease (PAD). 77.7% of ulcer were caused by physical factors. Questionnaire survey was conducted to collect the demographic data, present and past history, history of the hyperglycemia and lipid disorders, classification and phases of the foot ulcers based on Wagner' system and Texas system, characteristics of neuropathy and other diabetic complications, and relative risk factors. Detailed physical examination was performed, including 10 g nylon filament sensation examination., Results: The duration of diabetic foot of the patients with simple neuropathy was 3 (1, 60) months, significantly shorter than that of the diabetic foot patients with PAD [5 (1, 96) months, P < 0.001]. The Wagner degree of ulcer was related to the duration of diabetes, economic income, foot deformity, nerve reflection, diapason vibration sensation of foot, sensation point of 10 g nylon filament, ankle/brachial index (ABI), foot artery pulse, fasting blood sugar (FBS) and glycated hemoglobin (HbA1c). Stepwise regression analysis revealed that ABI of left posterior tibial artery, vibration detection threshold and economic income were the most significant influencing factors of the degree of ulcer., Conclusion: Neuropathy ulcer is common in diabetic foot patients. The prognosis of healing in diabetic foot with neuropathy is prior to that of diabetic foot with PAD. The neuropathy and PAD of foot influence each other and aggravate the condition of diabetic foot. The examinations of diapason vibration sensation of foot, sensation point of 10 g nylon filament, and Achilles tendon reflex are simple and practical, and are worth recommending.
