Objective To investigate the association of the polymorphism of resistin gene SNP-420C/G and type 2 diabetes (T2DM) among the Chinese Han population. Methods Such databases as CNKI, WanFang database, VIP, SinoMed, and PubMed were electronically searched from January 2001 to July 2010 to collect case-control studies on polymorphism of resistin gene SNP-420C/G and T2DM among the Chinese Han population. The quality of the included studies was evaluated and the data was extracted. RevMan 4.2 software was used for meta-analyses. Results A total of five case-control studies were identified, involving 709 cases in the T2DM group and 572 cases in the control group. The results of meta-analysis showed that the Chinese Han population with CC genotypes of SNP-420 had no higher risks to T2DM (OR=1.02, 95%CI 0.81 to 1.29), and the Chinese Han population with GG genotypes of SNP-420 still had no higher risks to T2DM (OR=1.34, 95%CI 0.95 to 1.90). Conclusion Current evidence suggests that there is no association between the polymorphism of resistin gene SNP-420C/G and risk to T2DM among the Chinese Han population.
ObjectiveTo systematically review the efficacy of interactive message management on patients with type 2 diabetes mellitus (T2DM).MethodsCNKI, VIP, WanFang Data, Web of Science, PubMed and The Cochrane Library databases were electronically searched to collect randomized controlled trials (RCTs) of T2DM with interactive message intervention from inception to May 2021. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies. Meta-analysis was then performed by using Revman5.3 software.ResultsA total of 17 RCTs involving 1 827 patients were included. Results of meta-analyses showed that compared with routine management, interactive message combined with routine management was associated with improvement of glycosylated hemoglobin, fasting blood glucose, body mass index, systolic blood pressure, and total cholesterol in T2DM patients. However, diastolic blood pressure, triglyceride, low-density lipoprotein, or high-density lipoprotein were not improved. ConclusionsThe current evidence shows that interactive message combined with routine management can significantly reduce blood glucose level, body mass index, systolic blood pressure and total cholesterol in T2DM patients. Due to the limited quality and quantity of the included studies, more high-quality studies are needed to verify the above conclusions.
ObjectiveTo understand the role of metformin on reducing incidence of type 2 diabetes mellitus (T2MD) patients complicated with liver cancer. MethodThe related literatures of metformin treated patients with T2MD complicated with liver cancer at home and abroad in recent years were reviewed. ResultsA large number of epidemiological and clinical data showed that the metformin might prevent the occurrence of the T2MD patients complicated with liver cancer, its mechanism was mainly inhibited the proliferation of hepatoma cells through the ATM-LKB1-AMPK-mTOR pathway, PI3K/Akt/mTOR pathway, or miRNA. The current controversy was the authenticity of the data, the influencing factors included the aging problem and characteristics of metformin user. The prospective study design rigorous remained to be clarified. ConclusionMetformin could reduce the incidence of T2MD patients complicated with liver cancer, and could inhibit the growth of liver cancer cells, which provides a new way of thinking for the comprehensive treatment of liver cancer.
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.

Conclusion:The insulin resistance was more worse in pedopathy of Type II diabetes.
ObjectiveTo systematically review the effect of intermittent fasting on type 2 diabetes mellitus. MethodsThe CNKI, WanFang Data, VIP, CBM, PubMed, Web of Science, The Cochrane Library and EMbase databases were electronically searched to collect randomized controlled trials (RCTs) on intermittent fasting intervention in the treatment of type 2 diabetes mellitus from inception to April 2022. Two reviewers independently screened the literature, extracted data, and evaluated the risk of bias of the included studies. The RevMan 5.4 software and Stata 17.0 software were used for meta-analysis. ResultsA total of 17 RCTs comprising 1 428 patients with type 2 diabetes mellitus were included. The results of meta-analysis showed that intermittent fasting improved body weight (WMD=−2.84, 95%CI −3.79 to −1.88, P<0.05), body mass index (BMI) (WMD=−1.07, 95%CI −1.52 to −0.61, P<0.05), glycosylated hemoglobin levels (SMD=−0.78, 95%CI −1.19 to −0.38, P<0.05), and fasting glucose levels (SMD=−0.65, 95%CI −1.01 to −0.3, P<0.05). ConclusionThe current evidence suggests that intermittent fasting improves body weight, BMI, glycated hemoglobin, and fasting blood glucose levels in patients with type 2 diabetes. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
Objective To assess the influence of different digestive tract reconstruction on the blood glucose of gastric antral cancer patients with type 2 diabetes. Methods The clinical data of 51 cases of gastric antral cancer with type 2 diabetes treated radical surgery in this hospital from January 2006 to January 2012 were analyzed retrospectively. The patients were divided into three groups according to the different digestive tract reconstruction methods：BillrothⅠ anastomosis group （n=14）， BillrothⅡ anastomosis group （n=28）， and Roux-en-Y anastomosis group （n=9）. The indexes were analyzed and compared among three groups：① The levels of fast blood glucose （FBG） and 2h postprandial blood glucose （PG2h） were detected before operation and on 1 month and 6 months after the operation；② The level of glycated hemoglobin （HbA1c） was detected before operation and 6 months after the operation；③ The diabetes control was observed. Results The FBG and PG2h levels in the BillrothⅠ anastomosis group detected on 1 month and 6 months after the operation were not statistically different from those detected before the operation （P＞0.05）. The FBG and PG2h levels in the BillrothⅡanastomosis group and Roux-en-Y anastomosis group detected on 1 month and 6 months after the operation were significantly lower than those before the operation respectively （P＜0.05）. The FBG and PG2h levels in the BillrothⅡ anastomosis group detected on 1 month and 6 months after the operation were not statistically different from those in the Roux-en-Y anastomosis group respectively （P＞0.05）， but which were markedly lower than those in the BillrothⅠ anastomosis group， the differences were statistically significant （P＜0.05）. The HbA1c levels in the BillrothⅠ anastomosis group detected before the operation and on 6 months after the operation were not statistically different from each other （P＞0.05）. The HbA1c levels in the BillrothⅡ anastomosis group and Roux-en-Y anastomosis group detected on 6 months after the operation were markedly lower than those before the operation and the difference was statistically significant （P＜0.05）. On 6 months after the operation， the HbA1c levels in the BillrothⅡanastomosis group and Roux-en-Y anastomosis group were markedly lower than those in the BillrothⅠ anastomosis group and the differences were statistically significant （P＜0.05）；the HbA1c level was not statistically different between the BillrothⅡ anastomosis group and the Roux-en-Y anastomosis group （P＞0.05）. The total curative effects in the BillrothⅡ anastomosis and Roux-en-Y anastomosis groups were significantly better than those in the BillrothⅠ anastomosis group （P＜0.05）. Conclusion According to our limited clinical data， BillrothⅡ anastomosis and Roux-en-Y anastomosis for gastric antral cancer patients with type 2 diabetes may be the best surgical approach.
