Objective To investigate the effect of type 2 diabetes mellitus on the prognosis of coronary heart disease patients who had a complication of heart failure with preserved ejection fraction. Metohds A retrospective study was performed with 393 coronary heart disease patients who were complicated with heart failure with preserved ejection fraction. The diagnosis was based on the results of echocardiography and coronary angiography at the heart center of the First Affiliated Hospital of Xinjiang Medical University assessed from January 2017 to December 2017. The patients were divided into diabetic group and non-diabetic group. The incidence of major adverse cardiovascular events (MACE) was compared between the two groups. In addition, the incidence of MACE was compared between the complete revascularization group and the incomplete revascularization group. Multivariate Cox regression analysis was used to analyze the effect of the risk factors on prognosis. Results The prevalence of hypertension and the use of ACEi/ARB in the diabetic group were higher than those in the non-diabetic group (P<0.05), and the level of high-density lipoprotein in the diabetic group was lower than that in the non-diabetic group (P<0.05). The incidence of MACE in the diabetic group (35.8%) was higher than that in non-diabetic group (25%, P=0.027). Complete revascularization improved the prognosis and reduced the incidence of MACE in both the diabetic group and non-diabetic group (P<0.05). Multivariate Cox regression analysis showed that a history of myocardial infarction (HR=0.44, 95%CI 0.20 to 1.00, P=0.049), incomplete revascularization (HR=17.28, 95%CI 2.34 to 127.43, P=0.005), and ejection fraction (HR=0.90, 95%CI 0.82 to 1.00, P=0.046) were associated with the occurrence of MACE in patients with coronary heart disease complicated with heart failure with preserved ejection fraction. Conclusion Type 2 diabetes mellitus affects the prognosis of coronary heart disease patients who have complication of heart failure with preserved ejection fraction. Complete revascularization can improve the prognosis of type 2 diabetic patients with coronary heart disease who have complications of heart failure with preserved ejection fraction.
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.
ObjectiveTo investigate the short-term efficacy of laparoscopic sleeve gastrectomy (LSG) for obesity with type 2 diabetes mellitus (T2MD) in China.
MethodsClinical randomized controlled trial literatures about domestic LSG treatment of obesity with T2MD were obtained from Wanfang Data, China Knowledge Resource Integrated Database, PubMed and Web of Science English Data. The literatures were selected according to the inclusive and exclusive criteria, then evaluated. Methodological quality assessment and meta analysis were evaluated according to the data extracted from those literatures. The short-term efficacy (fasting blood glucose or glycosylated hemoglobin) was evaluated after operation.
ResultsOne hundred and seven patients performed LSG were retrieved from 7 literatures. The levels of fasting blood glucose and glycosylated hemoglobin on the postoperative 6 months were all obviously decreased as compared with the levels before operation (fasting blood glucose:MD=2.99, 95% CI 2.39-3.60, P < 0.000 01; glycosylated hemoglobin:MD=2.24, 95% CI 1.43-3.04, P < 0.000 01), which on the postoperative 12 months were all obviously decreased as compared with the levels on the postoperative 6 months (fasting blood glucose:MD=0.56, 95% CI 0.16-0.95, P=0.006; glycosylated hemoglobin:MD=0.52, 95% CI 0.22-0.81, P=0.000 6). The postoperative fasting blood glucose and glycosylated hemoglobin levels in patients accepted LSG showed a downward trend.
ConclusionsLSG on obesity with T2MD has an obvious short-term curative effect. But its long-term efficacy still needs to be supported by large samples randomized controlled clinical research data.
Objective To systematically review the influencing factors of mild cognitive impairment in type 2 diabetic patients. MethodsPubMed, Web of Science, EMbase, The Cochrane Library, CNKI, WanFang Data, VIP, and CBM databases were electronically searched to collect studies on the influencing factors of mild cognitive impairment in patients with type 2 diabetes from inception to December 31, 2021. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias of included studies; then, meta-analysis was performed by using RevMan 5.4 software and Stata 12.0 software. ResultsA total of 32 studies involving 7 519 subjects were included. The results of the meta-analysis showed that the main influencing factors of mild cognitive impairment in type 2 diabetic patients were age, duration of type 2 diabetes, educational level, cerebral infarction, hypertension, smoking, insulin resistance index, glycosylated hemoglobin, and homocysteine. ConclusionCurrent evidence shows that some factors such as age, duration, and educational level are the main influencing factors of mild cognitive impairment in type 2 diabetic patients. Due to the limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusions.
ObjectiveTo evaluate the changes of nutritional status following sleeve gastrectomy with ileal interposition duodenojejunal bypass operation in treatment of nonobese type 2 diabetes mellitus.
MethodsA total of 47 patients submitted to sleeve gastrectomy with ileal interposition duodenojejunal bypass operation from March 2009 to November 2011 in this hospital were retrospectively analyzed. Serum iron, calcium, vitamin B12, folic acid, albumin (Alb), hemoglobin (Hb), glycosylated hemoglobin (HbA1c), and body mass index (BMI) were assessed before operation and on 6, 12, 24, and 36 months after operation.
Results①The values of Alb, Hb, HbA1c, and iron after operation were significantly lower than those of the corresponding values before operation (P < 0.01), the values of calcium, vitamin B12, folic acid, and BMI had no significant differences between after operation and before operation (P > 0.05).②The incidences of the lower Alb and lower iron after operation were significantly higher than those before operation (P < 0.01), the other indexes had no significant differences between after operation and before operation (P > 0.05).
ConclusionsSleeve gastrectomy with ileal interposition duodenojejunal bypass operation is an effective treatment of nonobese type 2 diabetes mellitus. However, nutritional deficiency is one of its side effects, which should be properly diagnosed and handled in order to improving the patient's quality of life and preventing related complications.
Objective To study the therapeutic effect of Roux-en-Y gastric bypass （RYGB） on type 2 diabetes mellitus （T2DM） rats and explore the possible mechanism of vaspin in RYGB on T2DM. Methods Twenty SD rats with T2DM and 20 age- and sex-matched normal SD rats were randomly divided into 4 groups according to the random digits table：T2DM-RYGB group， T2DM-sham operation （SO） group，RYGB group，and SO group，10 rats in each group. Fasting plasma glucose （FPG） level，serum insulin （INS） level，vaspin level，and homeostasis model of insulin resistance （HOMA-IR） were determined before operation and on week 4，8 after operation，respectively．At the same time，the correlation between vaspin and the indicators （FPG，INS，or HOMA-IR） was analyzed．Results Compared the indicators after operation with before operation，the FPG level，INS level，vaspin level，and HOMA-IR were not significantly different between the T2DM-RYGB group and T2DM-SO group （P＞0.05） or between the RYGB group and SO group （P＞0.05），but the FPG level，INS level，vaspin level，and HOMA-IR in the T2DM-RYGB group and T2DM-SO group were significantly higher than those in the RYGB group （P＜0.05） and SO group （P＜0.05），respectively. On week 4 after operation，the FPG level，INS level，vaspin level，and HOMA-IR decreased in the T2DM-RYGB group，except for the FPG level，the other indexes had no significant differences as compared with the values before operation. On week 8 after operation，the FPG level，INS level，vaspin level，and HOMA-IR further decreased in the T2DM-RYGB group，there were significant differences of these indicators between before operation and on week 8 after operation. Compared the indicators after operation with before operation，the FPG level，INS level，vaspin level，and HOMA-IR were not statistically significant （P＞0.05） in the T2DM-SO group，RYGB group，or SO group. The changes in serum vaspin level correlated positively with those in INS and HOMA-IR before operaion and on week 4，8 after operaion in the T2DM-RYGB group and T2DM SO group rats （P＜0.05），respectively. Conclusions RYGB surgery has a therapeutic effect on T2DM rats，and serum vaspin level decreases and insulin resistance is improved after RYGB surgery，which may be one of the mechanisms of the treatment for T2DM.
Objective To assess the therapeutic effect of gastric bypass on type 2 diabetes mellitus (T2DM) after a one-year treatment in Mainland China. Methods Databases including The Cochrane Central Register of Controlled Trials, MEDLINE, EMbase, CBM and CNKI were searched from inception to February 2012, and the relevant journals and references of articles were also searched to collect randomized controlled trials (RCTs) or before-after self-controlled trials on gastric bypass in treating T2DM in Mainland China. Two reviewers independently screened articles according to the predefined inclusion and exclusion criteria, extracted data, and evaluated quality of the included studies. Then meta-analyses were performed using RevMan 5.1.0. Results A total of 6 before-after self-controlled trials involving 131 patients were finally included. All these trials were graded as low quality. The results of meta-analysis showed that the therapeutic effect of gastric bypass on T2DM after a one-year treatment was good. There were significant reductions in both fasting plasma glucose (1 year: SMD=–2.55, 95%CI –3.40 to –1.69, Plt;0.000 01) and glycosylated hemoglobin (1 year: SMD=–1.98, 95%CI –2.33 to –1.62, Plt;0.000 01); there was no marked change in fasting insulin (SMD=–2.03, 95%CI –4.41 to 0.35, P=0.10). Sensitivity analysis indicated that these results were stable, but funnel-plots indicated possible publication bias existed. Conclusion One year after gastric bypass, T2DM patients in Mainland China get reduced in both fasting plasma glucose and glycosylated hemoglobin, but get no improvement in fasting insulin. However, this conclusion still needs to be further proved by more high-quality and large-scale clinical trials with long-term follow-up because of the limitation of quantity, scale and quality of the included studies.
ObjectiveTo study effect of expression levels of serum inflammatory factors and insulin receptor substrate(IRS)-1/2 in visceral adipose tissue after Roux-en-Y gastric bypass(RYGB) on type 2 diabetes mellitus(T2DM) rats, and explore possible mechanism in treatment of T2DM.
MethodsThe T2DM rats models were established, which were divided into 3 groups by intervention: T2MD-RYGB group(n=14), T2MD-sham operation(T2MD-SO) group(n=10), and T2MD group(n=10), and 10 normal rats were selected as control group. The rats of the T2MD-RYGB group were received the RYGB, and of the T2MD-SO group were received transection and reanastomosis of the gastroin-testinal tract. The fasting plasma glucose(FPG), fasting insulin(FINS), C-reaction protein(CRP), tumor necrosis factor-α(TNF-α), free fatty acid(FFA), homestasis model assessment for insulin resistance(HOMA-IR), adipose tissue insulin resistance(Adipo-IR) were tested respectively before operation and on week 1, 4, 8 after operation(synchronous detec-tion of rats with or without surgical intervention). The IRS-1 and IRS-2 protein contents of the rat epididymal adipose tissue were tested on week 8 after operation.
ResultsThe FPG, FINS, CRP, TNF-α, FFA levels, and HOMA-IR, Adipo-IR indexes in the T2DM rats were significantly higher than those in the normal rats(P < 0.05) before operation, the above indicators on week 4, 8 after operation were significantly lower than those before operation in the T2MD-RYGB group(P < 0.05). The differences of changes among the other groups were not statistically significant(P > 0.05). The IRS-1 and IRS-2 protein expressions in the adipose tissue of the rats were significantly increased in the T2MD-RYGB group as compared with these indicators in the T2MD group and T2MD-SO group(P < 0.05), but which were significantly lower than those in the control group(P < 0.05).
ConclusionsRYGB could increase IRS-1/2 expression levels in adipose tissue, which could enhance insulin sensitivity, decrease serum inflammatory factors levels, and improve insulin resistance ultimately. This might be one of the mechanisms in treatment of T2DM.
ObjectiveTo analyze the effect of type 2 diabetes (T2DM) on the short-term prognosis of patients with non-small cell lung cancer (NSCLC) after resection surgery.MethodsClinical data of 207 NSCLC patients who underwent resection surgery in our hospital from January 2016 to January 2019 were retrospectively analyzed. The 100 NSCLC patients with T2DM were allocated to a T2DM group (58 males and 42 females, with an average age of 65.26±7.26 years), and 107 patients without T2DM were allocated to a non-T2DM group (66 males and 41 females, with an average age of 64.21±7.51 years). The short-term prognosis of the patients was compared between the two groups.ResultsCompared with the non-T2DM group, the postoperative atelectasis (P=0.012) and pulmonary infection (P=0.040) were statistically different in the T2DM group. The postoperative complication rate in the T2DM group was significantly higher than that in the non-T2DM group (66.0% vs. 33.6%, P<0.001). The postoperative hospitalization time in the T2DM group was longer than that in the non-T2DM group (9.83±6.35 d vs. 8.09±4.40 d, P=0.007).ConclusionT2DM will increase the incidence of postoperative complications, prolong the length of hospital stay and increase the economic burden of the NSCLC patients, which is not conducive to the postoperative prognosis of patients.
Objective To investigate the current situation of self-monitoring of blood glucose (SMBG) in patients with type 2 diabetes mellitus (T2DM) in Sichuan province, and to analyze the influencing factors of SMBG, so as to provide evidence for improving the level of SMBG. Methods By the convenience sampling method, 410 patients with T2DM for more than 1 year were selected from 17 hospitals and community health service centers in 7 cities across Sichuan province, and their SMBG was investigated with a questionnaire. Results Among 410 eligible patients, the average frequency of SMBG was 7.3 times per month. There were 268 patients (65.4%) performed SMBG less than 4 times per month, 94 (22.9%) performed 4-15 times per month, 29 (7.1%) performed 6-29 times per month, and 19 (4.6%) performed over 30 times per month. Just 234 patients (57.1%) monitored the HbA1c in the past 6 months. FPG, 2-hour PPG and HbA1c were negatively correlated with the frequency of SMBG. The influencing factors of SMBG were insulin treatment and education. Conlusion The SMBG status in D2TM patients is relatively poor in Sichuan province, and the compliance of SMBG is expected to be improved by enhancing diabetic education.
