La diabetes mellitus tipo 2 (DM2) es una amenaza para la salud por las complicaciones derivadas de un diagnóstico tardío, donde la identificación oportuna es primordial. Con el objetivo de establecer la relación entre índice cintura talla (ICT), índice cintura cadera (ICC) y puntaje de la escala FINDRISC (Finnish Diabetes Risk Score) como determinantes del riesgo de padecer DM2 a largo plazo, se realizó este estudio predictivo transversal con adultos de 18 y 60 años atendidos en el Centro de Salud Primero de Julio del municipio de Mixco, Guatemala. Participaron 80 adultos, seleccionados por un muestreo aleatorio simple. El instrumento de recolección de datos estuvo conformado por tres secciones: información general de la persona, parámetros antropométricos y la encuesta de FINDRISC. Se generaron modelos lineales generalizados para identificar relaciones entre índice cintura talla (ICT), índice cintura cadera (ICC) y puntaje de la escala FINDRISC (Finnish Diabetes Risk Score). El 36.2% presentó riesgo de desarrollar DM2 a largo plazo; encontrándose un 21.2% en el nivel de riesgo alto y muy alto. Se comprobó que únicamente existe relación significativa entre el ICT y el puntaje de la escala de FINDRISC como determinante del riesgo de padecer DM2 a largo plazo. Se concluye que la implementación de la medición del ICT constituye una herramienta útil para identificar personas con riesgo de desarrollar DM2, siendo su aplicación sencilla, no invasiva, económica y de fácil acceso en los servicios de salud.
Type 2 diabetes mellitus (T2DM) is a health threat due to the complications derived from a late diagnosis, where timely identification is essential. This study aimed to establish the relationship between waist-height index (WHR), waist-hip index (WHR) and the FINDRISC (Finnish Diabetes Risk Score)scale as determinants of the risk of suffering from T2DM in the long term. A cross-sectional predictive study was carried out with a simple random sample of 80 adults between 18 and 60 years old treated at the Primero de Julio Health Center in Mixco, Guatemala. The data collection instrument was structured into three sections: general information, anthropometric parameters and the FINDRISC survey. Generalized linear models were generated to identify relationships between waist-height ratio (WHR), waist-hip ratio (WHR) and the FINDRISC scale score (Finish Diabetes Risk Score). The results shows that 36.2% of the participants were at risk of developing T2DM in the long term; 21.2% being at the high and very high risk level. It was found that there is only a significant relationship between the WHR and the FINDRISC scale score as a determinant of the risk of suffering from T2DM in the long term. The implementation of the waist height index measurement constitutes a useful tool to identify people at risk of developing T2DM, its application being simple, non-invasive, economical and easily accessible in health services.

Objective.To assess the effectiveness of an educational intervention on perceived stress and metabolic syndrome parameters among adults with type 2 diabetes mellitus. Method. Fifty-one adults (aged 48.73±7.84; 86.3% of women) were included in a non-randomized clinical trial performed in a healthcare unit for six months (Brazilian Clinical Trial Registry: RBR-43K52N). All participants were diagnosed with type 2 diabetes mellitus and metabolic syndrome (intervention group, n=26; control group, n=25). The intervention consisted of a nurse-led educational health-promoting program with a multidisciplinary approach organized in seven workshops. The primary outcome was decreased perceived stress, and the secondary outcome was improvement in metabolic syndrome parameters according to perceived stress levels. These outcomes were assessed at two points in time, at the baseline and follow-up. Results. Participation in the intervention program resulted in a significant decrease in perceived stress (p=0.028). The stressed participants in the intervention group experienced a significant decrease in blood glucose levels (p=0.001) and a significant increase in high-density lipoprotein-cholesterol (p=0.003) concentrations after the six-month intervention. Conclusion.The nurse-led educational health-promoting program decreased perceived stress among adults with type 2 diabetes mellitus and metabolic syndrome, improving fasting blood glucose and high-density lipoprotein cholesterol among the stressed participants in the intervention group.

Abstract Several reasons may underlie the dramatic increase in type2 diabetes mellitus. One of these reasons is the genetic basis and variations. Vitamin D receptor polymorphisms are associated with different diseases such as rheumatoid arthritis and diabetes. The aim of this study is to investigate the possible association of two identified mutations ApaI (rs7975232) and TaqI (rs731236). Eighty-nine healthy individuals and Fifty-six Type 2 Diabetic (T2D) patients were investigated using RFLP technique for genotyping and haplotyping as well. The distribution of Apal genotypes was not statistically significant among the control (P=0.65) as well as for diabetic patients (P=0.58). For Taql allele frequencies of T allele was 0.61 where of G allele was 0.39. The frequency distribution of Taql genotypes was not statistically significant among the control (P=0.26) as well as diabetic patients (P=0.17). Relative risk of the allele T of Apa1 gene is 1.28 and the odds ratio of the same allele is 1.53, while both estimates were 1.0 of the allele G. Similarly, with the Taq1 gene the relative risk and the odds ratio values for the allele T are 1.09 and 1.27 respectively and both estimates of the allele C were 0.86 for the relative risk and 0.79 for the odds ratio. The pairwise linkage disequilibrium between the two SNPs Taq1/apa1 was statistically significant in control group (D = 0.218, D' = 0.925 and P value 0.001) and similar data in diabetic groups (D = 0.2, D' = 0.875 and P value 0.001). These data suggest that the T allele of both genes Apa1 and Taq1 is associated with the increased risk of type 2 diabetes. We think that we need a larger number of volunteers to reach a more accurate conclusion.
Resumo Várias razões podem estar subjacentes ao aumento dramático da diabetes mellitus tipo 2. Um desses motivos é a base genética e variações.

O objetivo deste estudo é investigar a possível associação de duas mutações identificadas ApaI (rs7975232) e TaqI (rs731236). Oitenta e nove indivíduos saudáveis e 56 pacientes com diabetes tipo 2 (T2D) foram investigados usando a técnica RFLP para genotipagem e haplotipagem também. A distribuição dos genótipos Apal não foi estatisticamente significativa entre o controle (P = 0,65), bem como para os pacientes diabéticos (P = 0,58). Para as frequências do alelo Taql, o alelo T foi de 0,61, onde o alelo G foi de 0,39. A distribuição de frequência dos genótipos Taql não foi estatisticamente significativa entre o controle (P = 0,26), bem como os pacientes diabéticos (P = 0,17). O risco relativo do alelo T do gene Apa1 é 1,28 e a razão de chances do mesmo alelo é 1,53, enquanto ambas as estimativas foram 1,0 do alelo G. Da mesma forma, com o gene Taq1, os valores de risco relativo e razão de chances para o alelo T são 1,09 e 1,27, respectivamente, e ambas as estimativas do alelo C foram de 0,86 para o risco relativo e 0,79 para o odds ratio. O desequilíbrio de ligação par a par entre os dois SNPs Taq1 / apa1 foi estatisticamente significativo no grupo de controle (D = 0,218, D' = 0,925 e valor P 0,001) e dados semelhantes em grupos diabéticos (D = 0,2, D' = 0,875 e valor P 0,001). Esses dados sugerem que o alelo T de ambos os genes Apa1 e Taq1 está associado ao aumento do risco de diabetes tipo 2. Achamos que precisamos de um número maior de voluntários para chegar a uma conclusão mais precisa.

OBJECTIVE To study the interventional effect and mechanism of 1，8-cineole on pancreatic β cell ferroptosis induced by type 2 diabetes. METHODS In vitro ferroptosis model was established in pancreatic β cells of mice by using high glucose. The effects of low-dose and high-dose 1，8-cineole （0.25， 0.5 μmol/L） on the level of Fe2+ in pancreatic β cells were investigated. The effects of 1，8-cineole （0.5 μmol/L） combined with ferroptosis inducer Erastin （20 μmol/L） and ferroptosis inhibitor Ferrostatin-1 （20 μmol/L） on the protein expressions of glutathione peroxidase-4 （GPX4） and cyclooxygenase-2 （COX2） were also detected. The type 2 diabetes model mice were established by feeding high-sugar and high-fat diet combined with intraperitoneal injection of streptozotocin. The effects of low-dose and high-dose 1，8-cineole （50， 200 mg/kg） on the pathological morphology of pancreatic tissue， the content of iron as well as the protein expressions of GPX4 and COX2 were investigated. RESULTS The results of the cell experiment showed that compared with the model group， pretreatment with 1，8-cineole significantly reduced intracellular Fe2+ levels and upregulated GPX4 protein expression， while downregulated COX2 protein expression in pancreatic β cells （P＜0.05）. After combining with Ferrostatin-1， the expression trends of the above two proteins were the same， while there was no statistically significant difference after combining with Erastin. The results of animal experiments showed that compared with the model group， after intervention with 1，8-cineole， the structure of the pancreatic islets in mice recovered intact and their morphology improved； the iron content of pancreatic tissue and protein expression of COX2 were decreased significantly （P＜0.05）， while protein expression of GPX4 was increased significantly （P＜0.05）. CONCLUSIONS 1，8-cineole could ameliorate pancreatic β cell injury induced by diabetes， the mechanism of which may be related to reducing intracellular iron deposition and regulating ferroptosis-related proteins.

ObjectiveTo investigate the effect of Tangzhi pills on the improvement of insulin resistance （IR） in the liver with type 2 diabetes （T2DM） by regulating phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt） signaling pathway based on differential genes and its possible molecular mechanism. MethodT2DM rat models were prepared by high fat （HFD） diet combined with streptozotocin （STZ） intraperitoneal injection. The experiment was divided into blank group， model group， metformin hydrochloride group （0.18 g·kg-1）， Tangzhi pills high （1.08 g·kg-1）， medium （0.54 g·kg-1） and low （0.27 g·kg-1） dose groups. Rat serum， liver， and pancreatic tissue were collected， and the pathological tissue of the liver and pancreas was observed using hematoxylin-eosin （HE） staining. The fasting blood glucose level （FBG） was detected， and oral glucose tolerance （OGTT） tests were conducted. Enzyme-linked immunosorbent assay （ELISA） was used to detect fasting serum insulin （FINS） and glycated hemoglobin （GHb） levels in rats. IR homeostasis model index （HOMA-IR）， β cellular homeostasis index （HOMA-β）， and insulin sensitivity index （ISI） were calculated. Biochemical methods were used to determine the levels of triglyceride （TG）， total cholesterol （TC）， low-density lipoprotein （LDL-C）， and high-density lipoprotein （HDL-C） in rat serum. Transcriptomics obtained differentially expressed mRNA from liver tissue and enriched differentially expressed pathways. Real-time reverse transcriptase polymerase chain reaction （Real-time PCR） was used to detect the mRNA expression of cyclic adenylate responsive element binding protein 3-like protein 2 antibody （CREB3l2）， B-lymphocyte tumor 2 （Bcl-2）， Toll-like receptor 2 （TLR2）， cyclin-dependent kinase inhibitor 1A （CDNK1A）， and DNA damage induced transcription factor 4-like protein （DDIT4） in liver tissue. Western blot was used to detect the protein expression of phosphorylated phosphatidylinositol 3-kinase （p-PI3K）， phosphorylated protein kinase B （p-Akt）， glucose transporter 4 （GLUT4）， insulin receptor （INSR）， and insulin receptor substrate 2 （IRS2）. ResultThe pharmacodynamic experiment results showed that compared with model group， Tangzhi pills groups repaired liver and pancreatic tissue to varying degrees， reduced blood sugar （P<0.01）， and promoted a decrease in serum FINS， GHb， and HOMA-IR （P<0.05， P<0.01）. In addition， HOMA-β and ISI increased （P<0.05， P<0.01）. The levels of TC， TG， and LDL-C decreased （P<0.05， P<0.01）， while the levels of HDL-C increased （P<0.05， P<0.01）. The transcriptomics experimental results confirmed that the PI3K/Akt signaling pathway was significantly expressed in both the blank group and model group， as well as in the high-dose Tangzhi pills group and model group. CDNK1A， DDIT4， CREB3l2， Bcl-2， and TLR2 were significantly differentially expressed mRNA during TG intervention in T2DM. Compared with the model group， the protein expression of p-PI3K， p-Akt， GLUT4， INSR， and IRS2 increased in all Tangzhi pills groups （P<0.01）. The mRNA expression of CREB3l2， Bcl-2， and TLR2 increased （P<0.01）， while that of CDNK1A and DDIT4 decreased （P<0.01）. ConclusionTangzhi pills may regulate the PI3K/Akt signaling pathway based on the differential mRNA expression of CREB3l2， Bcl-2， TLR2， CDNK1A， and DDIT4， thereby improving IR in the liver with T2DM.

ObjectiveTo study the mechanism of astragaloside Ⅳ （AS Ⅳ） on db/db mice with type 2 diabetes mellitus （T2DM） and non-alcoholic fatty liver disease （NAFLD） based on network pharmacology and experimental validation. MethodA total of 24 db/db mice were randomly divided into four groups： model group， metformin group， and low-dose and high-dose AS Ⅳ groups. Six C57 mice were used as the blank group. The low-dose and high-dose AS Ⅳ groups were given AS Ⅳ of 0.015 and 0.030 g·kg-1 by gavage， and the metformin group was given 0.067 g·kg-1 by gavage. The blank and model groups were given equal volumes of distilled water by gavage. After intragastric administration， fasting blood glucose （FBG） was detected， and an oral glucose tolerance test was performed. Serum lipid level and liver histopathology were detected. The target and enrichment pathway of AS Ⅳ for treating T2DM and NAFLD were predicted by network pharmacology， and the main enrichment pathway was verified by molecular biology techniques. The protein expressions of AMPK， p-AMPK， sterol regulatory element-binding protein-1 （SREBP-1）， and fatty acid synthetase （FAS） in liver tissue were detected by Western blot. ResultCompared with the blank group， the levels of body mass， liver weight coefficient， fasting blood glucose， serum total cholesterol， triglyceride， and low-density lipoprotein cholesterol in mice treated with AS Ⅳ were decreased （P<0.05， P<0.01）. The pathology of liver tissue showed significant improvement in lipid accumulation， and imaging results showed that the degree of fatty liver was reduced after AS Ⅳ therapy. Network pharmacological prediction results showed that vascular endothelial growth factor α （VEGFA）， galactoagglutinin 3 （LGALS3）， serine/threonine kinase B2 （Akt2）， RHO-associated coiled-coil protein kinase 1 （ROCK1）， serine/threonine kinase B1 （Akt1）， signaling and transcriptional activator protein （STAT3）， and messtimal epidermal transformation factor （MET） were key targets in "drug-disease" network. The results from the Kyoto encyclopedia of genes and genomes （KEGG） enrichment showed that the AMP-dependent protein kinase （AMPK） signaling pathway was strongly associated with T2DM and NAFLD. Western blot results showed that compared with the blank group， the expression levels of p-AMPK/AMPK in the model group were significantly down-regulated， while those of SREBP-1 and FAS proteins were significantly up-regulated （P<0.01）. Compared with the model group， the expression levels of p-AMPK/AMPK in the metformin group and high-dose AS Ⅳ group were significantly up-regulated， while those of SREBP-1 and FAS proteins were significantly down-regulated （P<0.05， P<0.01）. ConclusionAS Ⅳ regulates the expression of lipid proteins by activating the AMPK signaling pathway， thereby improving lipid metabolism.

The contents of active ingredients in Erdongtang was detected by electrospray ionization（ESI） and multiple reaction monitoring（MRM） mode under positive and negative ion modes. On this basis， network pharmacology was applied to predict the targets and pathways of Erdongtang exerting anti-insulin resistance effect. ResultThe 20 active ingredients in Erdongtang showed good linear relationships within a certain mass concentration range， and the precision， stability， repeatability and recovery rate were good. The results of determination showed that the ingredients with high content in 15 batches of samples were baicalein（1 259.39-1 635.78 mg·L-1）， baicalin（1 078.37-1 411.52 mg·L-1）， the ingredients with medium content were mangiferin（148.59-217.04 mg·L-1）， timosaponin BⅡ（245.10-604.89 mg·L-1）， quercetin-3-O-glucuronide（89.30-423.26 mg·L-1）， rutin（46.91-1 553.61 mg·L-1）， glycyrrhizic acid（55.97-391.47 mg·L-1）， neomangiferin（37.45-127.03 mg·L-1）， nuciferine（0.89-63.48 mg·L-1）， hyperoside（6.96-136.78 mg·L-1）， liquiritin（30.89-122.78 mg·L-1）， liquiritigenin（26.64-110.67 mg·L-1）， protodioscin（58.57-284.26 mg·L-1）， the ingredients with low content were wogonin（7.16-20.74 mg·L-1）， pseudoprotodioscin（5.49-22.96 mg·L-1）， ginsenoside Rb1（7.31-23.87 mg·L-1）， ginsenoside Rg1（10.78-28.33 mg·L-1）， ginsenoside Re（7.78-24.76 mg·L-1）， ophiopogonin D（2.08-4.29 mg·L-1）， methylophiopogonanone A（0.74-1.67 mg·L-1）. The results of network pharmacology indicated that the mechanism of anti-insulin resistance exerted by Erdongtang might be related to the phosphatidylinositol 3-kinase/protein kinase B（PI3K/Akt） signaling pathway. ConclusionThe established UHPLC-QqQ-MS has the advantages of simple sample processing， strong exclusivity and high sensitivity， and can simultaneously determine the contents of the main ingredients from seven herbs in Erdongtang， which can lay the foundation for the development of Erdongtang compound preparations. The results of the network pharmacology can provide a reference for the mechanism study of Erdongtang in the treatment of type 2 diabetes mellitus.

Objective To investigate the changes of blood lipid and glycosylated hemoglobin (HbA1c) levels in obese type 2 diabetes (T2DM) patients and their relationship with insulin resistance (Homa-IR). Methods A total of 120 cases of T2DM newly diagnosed in Motuo County, Tibet from February to October 2022 were selected as the observation group. According to BMI, the patients were divided into diabetes normal weight group (46 cases), overweight group (43 cases) and obesity group (31 cases); 145 healthy subjects were selected as the control group. The levels of HbA1c, fasting blood glucose (FPG), fasting insulin (FINS), serum total cholesterol (TC), triglycerides (TG), high-density lipoprotein (HDL-C), and low-density lipoprotein (LDL-C) were detected in the study subjects, and Homa-IR and Homa-β indices were calculated. The height, weight, and abdominal circumference were measured. The differences in the levels of the above indicators between the observation group patients and the control group, as well as among various subgroups within the observation group were compared. The influencing factors of Homa-IR in obese T2DM patients were analyzed. Results Compared with the control group, a significant increase in BMI, abdominal circumference, blood pressure, HbA1c, FBG, FINS, TC, TG, LDL-C, UA, visceral fat area, and the levels of Home-IR and Home-β was found in the observation group (all P<0.05). There were significant differences in BMI, abdominal circumference, and the levels of FINS, Homa IR, Homa-β, and HbA1c in diabetes patients with different BMI (all P<0.05). Correlation analysis showed that TG levels in obese T2DM patients in the observation group were significantly correlated with HbA1c (r=0.396, P=0.027), Homa-IR (r=0.405, P=0.024), and Home-β (r=-0.401, P=0.025); LDL-C was significantly correlated with Homa-IR (r=0.411, P=0.022) and Homa-β (r=-0.412, P=0.021); HbA1c was significantly positively correlated with BMI (r=0.371, P=0.040). Conclusion Insulin resistance is closely related to TG, LDL-C, and BMI in obese T2DM patients from the Motuo ethnic minority of Tibet, suggesting that these factors may play a role in the occurrence of T2DM.
Résumé
Isoliquiritigenin (ISL) is an active chalcone compound isolated from licorice. It possesses anti-inflammatory and anti-oxidative activities. In our previous study, we uncovered a great potential of ISL in treatment of type 2 diabetes mellitus (T2DM). Therefore, this study aims to reveal the mechanism underlying the alleviatory effects of ISL on T2DM-induced glycolipid metabolism disorder. High-fat-high-sugar diet (HFD) combined with intraperitoneal injection of streptozotocin (STZ) were used to establish T2DM mice model. All animal experiments were carried out with approval of the Committee of Ethics at Beijing University of Chinese Medicine. HepG2 cells were used in in vitro experiments, and sodium palmitate (SP) was applied to establish insulin resistance (IR) model cells. The effects of ISL on body weight, fasting blood glucose levels, and pathological changes in the livers of mice were examined. Enzyme-linked immune sorbent assay (ELISA) and real-time quantitative PCR (RT-qPCR) were applied to detect the regulatory effects of ISL on key targets involved in glucolipid metabolism. Additionally, molecular docking and analytical dynamics simulation methods were used to analyze the interaction between ISL and key target protein. The results indicate that ISL significantly downregulates the transcriptional levels and inhibits the activities of key enzymes involved in gluconeogenesis, including pyruvate carboxylase (PC), phosphoenolpyruvate carboxykinase (PEPCK), and fructose-1, 6-bisphosphatase (FBP). It also downregulates the transcriptional and protein levels of hepatocyte nuclear factor 4α (HNF4α) and cAMP response element binding protein (CREB), the two transcriptional factors involved in gluconeogenesis. Thus, ISL inhibits hepatic gluconeogenesis in T2DM mice. In addition, ISL reduces total cholesterol (TC) and triglyceride (TG) levels in the livers of T2DM mice. Moreover, ISL downregulates the mRNA levels of lipogenesis genes and upregulates those of genes involved in fatty acid oxidation, lipid uptake, and lipid export. In conclusion, ISL suppresses hepatic gluconeogenesis, promotes lipolysis, and restrains lipogenesis in T2DM mice, thereby improving the abnormal glycolipid metabolism caused by T2DM.
Résumé
Berberine (BBR) is the main pharmacological active ingredient of Coptidis, which has hypoglycemic effect, but its clinical application is limited due to its poor oral bioavailability. Polyphenols, derived from cinnamon, are beneficial for type 2 diabetes mellitus (T2DM). The combination of both may have an additive effect. The aim of this study was to investigate the hypoglycemic effect and mechanism of combined medication in diabetic rats. The modeling rats were randomly divided into 5 groups (berberine group, cinnamon group, combined group, metformin group, diabetic control group) and normal control group. The animal experiments were approved by the Animal Ethics Committee (approval number: HMUIRB2022003). The subjects were given orally, and the control group was given equal volume solvent and body weight was measured weekly. Thirty days after administration, oral glucose tolerance test and insulin sensitivity test were performed, and fasting blood glucose (FBG), glycated serum protein (GSP), and serum insulin (INS) levels were detected; high-throughput sequencing technology was used to detect intestinal microbiota structure; real-time quantitative PCR (RT-qPCR) and Western blot were used to detect G protein-coupled receptor 5 (TGR5) and glucagon-like peptide-1 (GLP-1) expression levels. The results showed that, compared with the diabetic control group, the levels of FBG (P < 0.01) and GSP (P < 0.01) in the combined group were lower, and the insulin resistance was improved, which was better than that in the berberine group. Combined treatment increased the relative abundance of Bacteroides, Prevotella and Lactobacillus, reversed the decrease in Lactobacillus in the berberine alone induction group, and the combination of the two could promote the expression of TGR5 and GLP-1. In summary, the combined application of cinnamon and berberine can regulate glucose metabolism better than the application of berberine alone. Berberine combined with cinnamon can improve the function of pancreatic islet β cells in diabetes mellitus type 2 rats by changing the intestinal microbiota, increasing the expression of TGR5 and GLP-1 proteins, and thereby better regulating glucose metabolism.
Résumé
To develop a traditional Chinese medicine （TCM） diagnostic scale for type 2 diabetes mellitus with turbid-toxin accumulation syndrome and to validate the performance of the scale. A candidate pool was established through literature review and expert consultation， and a clinical case information collection form was developed accordingly. Patients with type 2 diabetes mellitus admitted to the First Teaching Hospital of Tianjin University of Traditional Chinese Medicine from July 2021 to January 2022 were investigated， and 312 valid clinical case information collection forms were obtained， which were randomly divided into 235 cases in the study group and 77 cases in the validation group. Four statistical methods， namely， differentiation analysis， Cronbach's coefficient， correlation coefficient， and stepwise regression， were used to screen out the candidate items， and Logistic regression analysis and factor analysis were used to assign weights to the items， and the final diagnostic model was determined by the receiver operating characteristic （ROC） curve， and the diagnostic thresholds were calculated for the Yoden index. The final TCM diagnostic scale for type 2 diabetes mellitus was composed of 8 items： turbid dirt coating （with a weight value of 23， the same below）， sticky stools （16）， fullness in the epigastrium and abdomen （12）， dark complexion （12）， irritability （11）， brown spots on the skin （11）， heaviness of head （10）， and chest stuffiness （5）， and the degree score was 0， 0.5， 1.0， and 1.5 points corresponding to no， mild， moderate and severe symptoms， respectively. The total score was the sum of the degree score multiplied by the weighted value of each item， and when the total score reached 33 points， it is diagnosed as the turbid-toxin accumulation syndrome. The established scale was tested and evaluated in the study group and the validation group， and the results showed that the sensitivity of the study group and the validation group was 89.38% and 89.47%， with the specificity of 95.90% and 89.74%， the Yoden index of 0.85 and 0.79， the positive predictive value of 95.28% and 89.47%， the negative predictive value of 90.70% and 89.74%， the diagnostic advantage ratios of 198.18 and 72.67， and the Kappa values of 0.86 and 0.79， which indicated that the TCM diagnostic scale for turbid-toxin accumulation syndrome of type 2 diabetes mellitus showed good diagnostic ability.
Résumé
Objective To study the status of diabetic foot and its related factors in Hanzhong area in recent years, and to provide a scientific basis for the prevention and management of diabetic foot complicated by type 2 diabetes. Methods A stratified sampling method was used to select 528 patients with type 2 diabetes among permanent residents in Hanzhong from April 2016 to April 2022. Relevant medical history and laboratory examination data were collected, and the incidence of diabetic foot was calculated. The influence of related factors on the risk of diabetic foot was analyzed by regression model. Results Among 528 subjects in this study, the disease course and body type of T2DM showed that male patients had significantly longer disease, and the proportion of overweight and obesity was higher, P2=27.516，P<0.05）. The proportion of male patients complicated with diabetic foot was higher than that of female patients (P<0.05). At the same time, the incidence of Wagner Grade I was higher in males than in females (P<0.05). The effects of potential factors on the risk of diabetic foot were discussed by gender. Univariate analysis and multivariate logistic regression analysis indicated that the risk factors of diabetic foot in male T2DM patients included: Increased course of disease, increased age, poor blood glucose control, increased total cholesterol level, increased BMI level and increased platelet to lymphocyte ratio . Potential risk factors in women include increased course of disease, age, poor blood sugar control (increased glycosylated hemoglobin levels) and increased platelet to lymphocyte ratios in all cases（P<0.05）. Conclusion The current prevalence rate of type 2 diabetes patients complicated with diabetes foot in Hanzhong area is 16.29%, which is still high , and the prevalence rate of men is significantly higher than that of women. Older age, long duration of T2DM, poor blood glucose control, increased total cholesterol level, increased blood uric acid level, decreased urine pH value, and increased platelet lymphocyte ratio are potential risk factors for diabetes foot. Male patients should also pay attention to the occurrence of overweight and obesity tendency to reduce the risk of diabetes foot.
Résumé
AIM: To observe the real world efficacy of continuous subcutaneous insulin infusion (CSII) with insulin pump in short-term intensive treatment of patients with type 2 diabetes (T2DM) and explore the influencing factors associated with efficacy. METHODS: A total of 369 hospitalized T2DM patients were treated with CSII short-term intensive therapy. Based on the blood glucose levels on the 5th day of treatment, they were divided into two groups, namely the qualified blood glucose control group and the non-qualified blood glucose control group. The differences of glucose metabolism, physiology, biochemistry and other indicators between the two groups were compared, and the influencing factors of insulin pump efficacy were analyzed by regression statistics. RESULTS: After 4 days of CSII short-term treatment, 225 patients (61%) achieved blood glucose control standards, while 144 patients (39%) did not achieve blood glucose control standards. Compared with the qualified blood glucose control group, the non-qualified blood glucose control group was older and with higher levels of total daily insulin dose per kilogram of body weight (TDD), fasting blood glucose (FBG), fasting insulin, fasting C-peptide, and insulin resistance index (HOMA-IR), while lower levels of blood phosphorus, insulin growth factor 1 (IGF1). In terms of biochemical indicators, there was no significant difference between the two groups as a whole, including blood lipid levels, liver function, and kidney function. The results of univariate regression and multivariate stepwise regression analysis showed that 2-hour postprandial insulin, TDD and blood phosphorus were the key factors influencing the efficacy of Insulin pump. Among them, qualified blood glucose control was positively correlated with blood phosphorus, and negatively correlated with 2-hour postprandial insulin and TDD. CONCLUSION: CSII with insulin pump is an ideal method for short-term intensive treatment of type 2 diabetes. In order to achieve a more satisfactory rate of qualified blood glucose control, more attention should be paid to the patient's blood phosphorus, 2-hour postprandial insulin and TDD in clinical use.

AIM: To observe the effect of RBC preservation solution with sodium pyruvate on the morphology, structure and function of RBC stored in vitro in type 2 diabetes rats. METHODS: Thirty SPF male SD rats, were randomly divided into 3 groups (n=10): non-T2DM conventional RBC preservation solution (group A), T2DM conventional RBC preservation solution (group B) and T2DM sodium pyruvate RBC preservation solution (group C). The leukoreduced RBC from the tail vein and stored for 0 d (T0), 7 d (T1), 14 d (T2), 21 d (T3) and 28 d (T4) to detect the morphology, structure and the contents of 2, 3-DPG, reactive oxygen species (ROS), malondialdehyde (MDA) and lactic acid (LA) of RBC in group A, B and C. The RBC stored for 14 days in vitro were labeled with PKH26, and its survival rate were tested in vivo at 1, 4, 10 and 16 hours after intravenous infusion. RESULTS: At T0, the RBC morphology of group A was intact, which was better than that of group B and group C. With the extension of storage time, the morphology of RBC in each group gradually transformed into a spindle-spherical shape. Compared with group A, the incidence of acanthocytes in group B and group C was higher, and the incidence of acanthocytes in group C was lower than that in group B. Compared with group A, the content of 2, 3-DPG in group B and group C decreased, while ROS and MDA increased at different time points (P<0.05). The content of 2,3-DPG in group C was higher than that in group B (P<0.05), and the contents of ROS and MDA were lower than those in group B (P<0.05). LA content in group B was higher than that in group A and group C (P<0.05). At T2-T4, the LA content in group C was lower than that in group A (P<0.05). The survival rate of RBC in group A was higher than that in group B and C, and the survival rate of RBC in group B was lower than that in group C (P<0.05). CONCLUSION: Sodium pyruvate added RBC preservation solution has a certain protective effect on RBC stored in vitro in type 2 diabetic rats, and its mechanism may be related to its antioxidant effect.

AIM: To investigate the clinical features of acute exacerbation chronic obstructive pulmonary disease (AECOPD) of complicated with type 2 diabetes mellitus (T2DM), and analyze the related clinical features and risk factors. METHODS: This was a single-center cross-sectional study. From March 2020 to January 2023, 479 hospitalized patients with AECOPD in the department of respiratory and critical care medicine, Suining Central Hospital were included. There were 215 patients in AECOPD group and 60 patients in AECOPD with T2DM group. The collected variables included demographic data, complications, blood routine, infection index, random blood glucose, blood gas analysis and lung function. The adoption rate and constituent ratio of the basic description classification data were expressed as mean standard deviation for the normal distribution measurement data and median interquartile range for the skew distribution measurement data. T-test was used for normal distribution and non - parameter test was used for non-normal distribution. The categorical variables were tested by chi-square test. Rank sum test was used for rank variable data. Binary logistic regression model was used to investigate the independent factors associated with T2DM in patients with AECOPD. Finally, the results of logistic regression were verified and visualized by nomogram, validation curve, ROC curve and DCA curve. P0.05). The results of logistic regression were verified and visualized by Nomogram and its-associated ccurves. The MAE and AUC curves were 0.021 and 0.847 respectively, indicating that the model had good prediction consistency and accuracy. The DCA curve showed that Nomogram's risk threshold ranged from 0.01 to 0.99, suggesting that nomogram's model had better clinical predictive value. CONCLUSION: Our results showed that increased BMI, PaCO2 and random glucose, decreased blood lymphocyte, and atrial fibrillation is an independent clinical feature of AECOPD with T2DM. These results suggest that the immune function of patients with AECOPD and T2DM are more severely impaired and more likely to be accompanied by atrial fibrillation, which is a potential cause of poor prognosis in these patients. Meanwhile, this conclusion needs to be further verified in multicenter study with large sample size.
Résumé
Glucagon-like peptide-1 ( GLP-1 ) is secreted by gut enteroendocrine cells. GLP-1 receptor agonists ( GLP-1 RAs) control glucose-related augmentation of insulin and suppress glu-cagon secretion. GLP-lRAs also inhibit gastric emptying, food intake and limit weight gain. In the past decade, significant progresses have been made in the investigation on the effects of GLP-1 RAs on cardiovascular system. The potential advantages of oral small-molecule GLP-1 RAs could improve the application of this class of drugs. This review highlights the multiple cardiovascular profiles of GLP-1 RAs in the treatment of cardiovascular diseases to provide new insights into cardiovascular benefits of GLP-1 RAs.
Résumé
@#Introduction: Previous studies have suggested that young individuals with type 2 diabetes mellitus (T2DM) face challenges in achieving optimal diabetes self-management, leading to difficulties in attaining the recommended glycaemic target. The reasons behind these suboptimal practices remain unclear due to the limited number of studies conducted in Malaysia that focused on diabetes self-management among young people. This qualitative study aimed to understand the lived experience of young people with T2DM on self-management in Malaysia. Methods: Young people at the age of 10 to 24 years, who had been diagnosed with T2DM and the caregivers who managing young people with T2DM were interviewed. Data were thematically analysed with the aid of QSR NVivo version 12. Results: Sixteen young informants and eleven caregivers participated in this study. Three major themes conceptualised the lived experience of diabetes self-management: (1) the trajectory to T2DM diagnosis; (2) perceived causes of T2DM; (3) the efforts in diabetes self-management. The route of diagnosis and experiential knowledge about T2DM might determine their efforts in the self-management among the young people. Healthy eating, medication taking and physical activity were perceived as important tasks in diabetes self-management. The involvement of the caregivers in diabetes self-management evolved over time. Conclusion: The study highlighted the experience of young people and caregivers since the beginning of the diagnosis and their strategies in diabetes self-management. More understanding of the lived experiences of patients and caregivers in disease management within the socio-ecological context could help to improve health-care services and intervention for this population.
