Objective To evaluate the effectiveness of diabetic patient education on glycemic control for diabeties. Methods Fifty cases of type 2 diabetic patients with educational interventions from the Diabetic Educational Center of West China Hospital and 50 type 2 diabetic patients without educational intervention were selected randomly. All the patients completed the same questionnaire. The data were analyzed by SPSS 10.0. Results The age of patients in educational group was older and the duration of sickness was longer than those in the control group, but their blood glucoses were better controlled. Conclusions Diabetic patient education is important to improve their glycemic control and decrease the risks and deterioration of diabetic chronic complications.
Objective To explore the correlation between blood glucose and self-management behaviors in patients with type 2 diabetic mellitus before initial basal insulin therapy. Methods A convenient sample of 200 patients with type 2 diabetic mellitus who were hospitalized in a tertiary hospital from February to August 2016 were enrolled in the study on a voluntary basis. Patients’ demographic information, fast blood glucose, glycosylated hemoglobin, and scores of diabetes self-care activities were gathered through questionnaires. Results A total of 193 valid questionnaires were recovered. Before starting basal insulin therapy, the mean blood glucose and the mean glycosylated hemoglobin of the 193 patients were (12.22±3.95) mmol/L and (10.01±2.38)%, respectively, with 12 patients (6.22%) meeting the goal of fasting blood glucose ≤7 mmol/L and 18 patients (9.33%) meeting the goal of glycosylated hemoglobin <7%, respectively. The total score of self-care activities was 26.76±14.77, in which 3 patients (1.55%) performed well. Spearman analysis demonstrated that the total score of self-care activities was negatively correlated with fast blood glucose ( r=–0.401, P<0.001) and glycosylated hemoglobin (r=–0.227, P=0.028). Conclusions The blood glucose levels and self-management behaviors in diabetic patients at the beginning of initial basal insulin therapy are not optimistic. Enhanced management of type 2 diabetic patients with initial basal insulin therapy is the prerequisite to promote diabetes self-care activities.
Objectives To systemically review and investigate the efficacy of intensive glucose control in Type 2 diabetes mellitus. Methods Database searches of MEDLINE, EMBASE, Cochrane Controlled Trials Register, VIP Database, CNKI, and CBM disc (from the date of establishment of the databases to June 2009) were conducted. Additional studies were retrieved via references of articles and direct contact with the authors to retrieve relevant data. Prospective, randomized controlled trials of intensive glucose control compared with standard therapy in diabetic patients were selected. We accessed the quality of included trials and extracted the relevant data. Statistical analysis was performed using The Cochrane Collaboration’s software RevMan 5.0. Results Eight trials with a total of 37 004 participants were included. The Meta-analysis showed: intensive glucose therapy was associated with a significant 9% reduction in the odds of cardiovascular events [OR=0.91, 95%CI (0.85, 0.98), P=0.007], and a 26% reduction in the microvascular events [OR=0.74, 95%CI (0.60, 0.91), P=0.005]. For the peripheral vascular events, no statistical difference was found between intensive therapy and standard therapy [OR=0.94, 95%CI (0.83, 1.07), P=0.35]. No statistical difference could be found in total mortality [OR=1.00, 95%CI (0.92, 1.08), P=0.98] and cardiovascular mortality [OR=1.03, 95%CI (0.83, 1.28), P=0.77]. Intensive therapy could increase more than 1.1-fold odds of hypoglycemia compared with standard-therapy [OR=2.12, 95%CI (1.24, 3.60), P=0.006]. Conclusions Findings from this meta-analysis suggest that intensive glucose control significantly reduces the risk of cardiovascular events and microvascular events, and increases the risk of hypoglycemia, while no prominent difference is found in mortality.

Objective Through studying a diabetic patient accompanied with pancreatic cancer by means of evidence-based clinical practice, to find out the relationship between diabetes mellitus and cancer and whether the long-acting insulin glargine increases the risk of cancer or not, which is regarded as a disputable hot issue at present. Methods Such databases as The Cochrane Library (Issue 3, 2010), OVID-EBM Reviews (1991 to Sept. 2010), MEDLINE (1950 to Sept. 2010) and CNKI (2000 to Sept. 2010) were retrieved to collect high quality clinical evidence, and the best therapy was formulated in accordance with the willingness of patients themselves. Results Eight randomized controlled trials (RCTs), four meta-analyses and one RCT meta-analysis were included. The evidence indicated that: a) Diabetes mellitus was kind of related to the occurrence of malignancies; b) There was no evidence at present showing the relationship between long-acting insulin glargine and cancer; c) Strictly controlling of blood sugar did not increase the risk of tumorigenesis, but hyperglycemia causing cancer was proofless; and d) Whether the diabetic patient with cancer should stop taking long-acting insulin glargine or not should require suggestions from specialists rather than patients themselves. Conclusion No evidence at present shows that tumorigenesis is related to diabetes mellitus, long-acting insulin glargine and strict controlling of blood sugar. It is necessary to require more evidence to decide whether the therapy should be adjusted or not for the diabetic patient with cancer who is in the process of glargine therapy.
Objective To evaluate clinical effects of strict control vs. conventional control of blood glucose in perioperative cardiac surgery. Methods Databases including PubMed, EMbase, HighWire, The Cochrane Library, CBM and VIP were searched to collect the randomized controlled trials (RCTs) on strict control vs. conventional control of blood glucose in perioperative cardiac surgery, published from 2000 to 2011. Two reviewers independently screened articles according to the inclusion and exclusion criteria, extracted data, and assessed quality of the included studies. Then meta-analysis was performed using RevMan 5.1. Results A total of 8 RCTs involving 2 250 patients were included. The results of meta-analysis showed that compared with the conventional group, the strict control of blood glucose could reduce postoperative short-term mortality (OR=0.52, 95% CI 0.30 to 0.91, P=0.02) and postoperative incidence rate of both atrial fibrillation (OR=0.64, 95%CI 0.43 to 0.96, P=0.03) and incision infection (OR=0.30, 95%CI 0.15 to 0.57, P=0.000 2), and shorten hospital stay (MD=1.75, 95%CI –3.18 to –0.32, Plt;0.02) and time of mechanical ventilation (MD=–0.9, 95%CI –1.43 to –0.38, Plt;0.000 8). Conclusion Current evidence shows that the strict control of blood glucose in perioperative cardiac surgery can reduce postoperative short-term mortality and postoperative incidence rate of both atrial fibrillation and incision infection, shorten hospital stay and time of mechanical ventilation, and have important clinical values and social and economic significance. However, this conclusion has to be proved by more high-quality and large-scale RCTs for the limitation of quantity and quality of the included studies.
ObjectiveTo provide the best evidence for an old diabetic patient who combined with frailty syndrome with the goal of glycemic control, treatment strategy and their prognosis. MethodsPubMed, MEDLINE (Ovid), EMbase, The Cochrane Library (Issue 11, 2015) and CNKI were searched from their inception to Nov. 2015, to collect evidence about the management of glycemic control. Evidences were analyzed by the way of evidenced-based criterions. ResultsOne clinical guideline, one meta-analysis, three RCTs, seven cohort studies and four case-control studies were included. Evidence showed that compared with patient uncombined with frailty, old diabetic patients with frailty had a higher prevalence of dementia, cardiovascular diseases and death; Aggressive glycemic control could not reduce the prevalence of cardiovascular events and the risk of death, while it could increase the risk of falling. Glycemic control was more comprehensive which would be taken frailty into consideration. Diet rich in protein (especially leucine), resistance exercise and reasonable medications based on comprehensive geriatric assessment were proved benefit for the old diabetic patient. ConclusionThe incidence of cardiovascular events, hypoglycemia and mortality are increased in this old diabetic patient who combined with frailty. Maintaining HbA1c around 7.5% is reasonable and diet with enough calorie and rich in protein (especially leucine), resistance exercises should be recommended for the person.
ObjectiveTo investigate the epidemiological characteristics and predisposing causes of diabetic foot ulcer (DFU) in the hospitalized patients with diabetic foot disease (DFD).MethodsThe clinical data of patients with DFD admitted to West China Hospital of Sichuan University between January 1st, 2012 and December 31st, 2018 were collected through the electronic medical record system. The demographic characteristics, blood glucose control status, and the predisposing causes of DFU were analyzed.ResultsA total of 1 022 DFD inpatients with an average age of (65.5±11.9) years old were included in this study, including 679 males and 343 females; 59.4% (513/864) of the patients had a college degree or above, but the patients with more severe DFD had lower educational level (χ2trend=19.554, P<0.001). The average time from diagnosis of diabetes mellitus to occurrence of DFD was (10.6±7.1) years, and 42.4% (433/1 022) of the patients had diabetes for over 10 years. Among the patients, 82.3% (841/1 022) treated diabetes irregularly, 56.2% (555/987) never monitored blood glucose, 51.2% (523/1 022) had a history of foot ulcers, and 8.6% (88/1 022) had a history of lower extremity or toe amputation. The average fasting blood glucose and hemoglobin A1c were (8.6±3.8) mmol/L and (8.2±2.1)%, respectively. There were 52.2% (525/1 006) and 94.4% (958/1 015) of the DFD patients companied with peripheral arterial disease and neuropathy, respectively. DFUs were mainly single (52.7%, 447/849) and neuro-ischemic ulcers (53.0%, 389/734). The main predisposing causes were physical causes (21.6%, 180/834) and trauma (19.2%, 160/834).ConclusionsThe patients with DFD have the characteristics of old age, long course of diabetes, irregular treatment of diabetes and poor control of blood glucose, combined with neurovascular diseases, and high recurrence rate of foot ulcer. Therefore, diabetes education, early screening of foot risk factors, and early intervention should be strengthened to prevent the occurrence and recurrence of DFU.
ObjectiveTo observe the lipid metabolism characteristics of type 2 diabetes mellitus (T2DM) patients with different levels of blood glucose control and preliminarily analyze their relationship with diabetic retinopathy (DR). MethodsA retrospective clinical study. From January 2019 to January 2024, 232 T2DM patients who underwent fundus examination in Department of Ophthalmology of Yichang Central People’s Hospital were included in the study. Based on the glycated hemoglobin A1c (HbA1c) test results, patients were divided into blood glucose standard group and blood glucose non standard group, with 100 and 132 cases respectively. Based on the results of fundus fluorescein angiography, patients were divided into non DR (NDR) group and DR group, with 89 and 143 cases, respectively. 100 healthy individuals who underwent physical examinations during the same period were selected as the control group. The thickness of peripapillary retinal nerve fiber layer (pRNFL) around the optic disc, the blood flow density of radial peripapillary capillaries (RPC) around the optic disc, and the thickness of ganglion cell complex (GCC) in the upper and lower parts of the optic disc and macular area were measured by optical coherence tomography angiography instrument. Fully automated biochemical analyzer was used to detect serum levels of total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and HbA1c. After adjusting for confounding factors, multiple linear regression model was used to analyze the correlation between HbA1c and blood lipids. Multiple logistic regression analysis was conducted to investigate the correlation between TG, HDL-C, and the occurrence of DR. ResultsCompared with the control group, both the blood glucose standard group and the blood glucose non standard group had higher levels of HbA1c (F=8.115), TC (F=4.373), TG (F=20.220), and LDL-C (F=12.271), and lower levels of HDL-C (F=6.349), with statistically significant differences (P＜0.05). Compared with the blood glucose standard group, patients in the blood glucose non standard group had higher levels of serum HbA1c (t=3.531), TC (t=2.561), TG (t=6.418), LDL-C (t=7.880), and lower levels of HDL-C (t=5.152), with statistically significant differences (P＜0.05). Correlation analysis showed that HbA1c was positively correlated with TC, TG, and LDL-C (P＜0.05), and negatively correlated with HDL-C (P＜0.05). Multiple logistic regression analysis showed that TG, LDL-C, and HDL-C were independent risk factors for the occurrence of DR (Ptrend＜0.05). Compared with the NDR group, the DR group had thinner GCC and pRNFL thickness in the upper part of the optic disc, and lower overall and RPC blood flow density in the upper part of the optic disc, with statistically significant differences (t=4.964, 2.406, 2.685, 2.404; P＜0.05). Correlation analysis results showed that TG, LDL-C, HDL-C, HbA1c were correlated with GCC thickness, pRNFL thickness, and RPC blood flow density (P＜0.05). ConclusionsThe higher the blood glucose level in T2DM patients, the more likely they are to experience dyslipidemia. TG, LDL-C, and HDL-C are independent risk factors for the occurrence of DR. Abnormal blood lipids and blood glucose levels in T2DM patients can affect retinal nerves, blood vessels, and function.
