RESUMEN
Objective: The authors' aim in this systematic review was to verify the scientific evidence for difference of oxidative stress biomarkers in individuals with type 2 diabetes mellitus with and without periodontitis. Material and Methods: Observational studies, baseline data of prospective and interventional studies were searched on the following databases: Virtual Health Library, Web of Science, PubMed, Embase, Scopus, Cochrane Library, Opengrey and Google Scholar. The electronic search was performed in June 01, 2020 until May 17, 2024 with alerts until June 01, 2024. The quality assessment and the certainty of the evidence of the included studies were evaluated through Fowkes and Fulton's checklist and GRADEpro Guideline Development Tool. Results: Of 988 relevant articles, the authors included 9 studies for the final analysis. Among those studies, 4 cross-sectional, 3 case-control, and 2 interventional studies were included. The analysis of non-randomized clinical trials properly reported most of the criteria analyzed in Summary questions (Bias, Confounding and Chance) as present in 3 studies. In six studies confounding factors were no detected. Due to the variation in the study results and clinical/methodological heterogeneity, a meta-analysis was not appropriate. The studies reported high concentrations of oxidizing agents and low antioxidants levels in individuals with type 2 diabetes mellitus and periodontitis when compared to with no periodontitis. Conclusion: Considering the few studies found, the methodological flaws, few markers studied and absence homogeneity in the evaluation of redox balance markers, as well as, the very low certainty of the evidence among included studies, it was not possible to determine whether there are or not differences in the oxidative stress levels in individuals with type 2 diabetes with and without periodontitis, and therefore, further prospective observational and interventional studies are recommended.

Objetivo: O objetivo dos autores nesta revisão sistemática foi verificar a evidência científica para a diferença de biomarcadores de estresse oxidativo em indivíduos com diabetes mellitus tipo 2 com e sem periodontite. Material e Métodos: estudos observacionais, dados de base de estudos prospectivos e intervencionistas foram pesquisados nas seguintes bases de dados: Biblioteca Virtual em Saúde, Web of Science, PubMed, Embase, Scopus, Cochrane Library, Opengrey e Google Scholar. A busca eletrônica foi realizada no período de 01 de junho de 2020 até 17 de maio de 2024, com alertas até 01 de junho de 2024. A avaliação da qualidade e a certeza da evidência dos estudos incluídos foi realizada através da lista de checagem Fowkes and Fulton's e da Ferramenta de desenvolvimento de diretrizes GRADEpro. Resultados: Dos 988 artigos relevantes, os autores incluíram 9 estudos para a análise final. Entre esses estudos, foram incluídos 4 estudos transversais, 3 de caso-controle e 2 de intervenção. A análise dos ensaios clínicos não randomizados relatou adequadamente a maioria dos critérios analisados nas questões resumo (Viés, Confundimento e Resultados ao caso) presentes em 3 estudos. Fatores de confusão não foram detectados em seis estudos. Devido à variação nos resultados do estudo e à heterogeneidade clínica/metodológica, não foi possível realizar uma meta-análise. Os estudos relataram altas concentrações de agentes oxidantes e baixos níveis de antioxidantes em indivíduos com diabetes mellitus tipo 2 e periodontite quando comparados a indivíduos sem periodontite. Conclusão: Considerando os poucos estudos encontrados, as falhas metodológicas, poucos marcadores estudados e ausência de homogeneidade na avaliação dos marcadores do balanço redox, bem como a baixíssima certeza da evidência entre os estudos incluídos, não foi possível determinar se há diferenças nos níveis de estresse oxidativo em indivíduos com diabetes tipo 2 associado e não à periodontite e, portanto, outras observações prospectivas e estudos de intervenção são recomendados (AU)

RESUMEN
ObjectiveTo study the impact of type 2 diabetes mellitus on endothelium of great saphenous vein in patients with coronary heart disease.MethodsPatients undergoing coronary artery bypass grafting were selected, 20 with type 2 diabetes mellitus (experimental group) and another 20 patients without (control group).The rings of great saphenous vein in I cm length were taken from those patients and then divided into 3 segments.The structure of endothelium was evaluated by the microscope and the changes of venous tone were measured in organ chamber at 37C with a constant supply of oxygen.Venous vasoconstriction was induced by phenylephrine (10-5 mol/L) and vasodilatation induced by nitroglycerin or acetylcholine (10-9 ～ 10-5 mol/L).ResultsMore damages of ultrastructure of the endothelium of saphenous vein were found in experimental group than in control group.There were no significant differences regarding the venous tone between the two groups (P ＞0.05) when vasoconstriction induced by phenylephrine and vasodilatation by nitroglycerin.However, the vasodilatation induced by acetylcholine was significantly decreased in experimental group than in control group (P ＜ 0.05).Conclusion Type 2 diabetes mellitus can aggravate the damage of endothelium of saphenous vein in patients with coronary artery disease.
RESUMEN
Objective To explore a sensitive method and index to evaluate renal functional reserve (RFR) in patients with early diabetic nephropathy (DN) using protein loading-scintirenography.Methods Fifty subjects were studied and divided into 3 groups.Group one (G1) consisted of 14 healthy volunteers;Group two (G2) consisted of 15 patients with type 2 diabetes mellitus (DM) and normoalbuminuria; Group three (G3) consisted of 21 patients with type 2 DM and microalbuminuria.All subjects underwent baseline and protein loading-99 Tcm-DTPA scintirenography within one week.RFR was calculated as the difference between stimulated and baseline glomerular filtration rate (GFR), time of peak ( Tb ), time of half excretion ( C1/2 ), residual rate at 20 min ( C20/b ) .Variance analysis and t-test were used to analyze the group differences.Results ( 1 ) The RFR in terms of GFR had statistical difference between any two groups (t=14.884, 32.180, 16.042, all P＜0.01).After protein-loading, the GFR of G1, G2 and G3 increased 20.1, 10.9 and 2.2 ml·min-1·1.73 m-2 respectively.Therefore, the RFR decreased before microalbuminuria in type 2 DM patients.(2)There was statistical difference between the RFR of G1 and G2 in terms of C1/2 (t = 5.505, P＜0.05 ), and between G1 and G3 ( t = 8.914, P＜0.01 ).(3) There was statistical difference of the RFR in terms of TP between G1 and G3 (t = 5.690, P ＜ 0.01 ).(4) There was statistical difference of the RFR in terms of C20/b between G1 and G3 (t= 4.376, P＜0.05 ).Conclusions 99Tcm-DTPA protein loading-scintirenography is an effective method for measuring RFR to evaluate early DN in type 2 DM patients.
RESUMEN
Objective The purpose of this study was to develop a high-throughput micro-plate radiobinding assay (RBA) of glutamic acid decarboxylase antibody (GAD-Ab) and to evaluate its clinical application. Methods 35labeled GAD65 antigen was incubated with sera for 24 h on a 96-well plate, and then transferred to the Millipore plate coated with protein A, which was washed with 4℃ PBS buffer, and then counted by a liquid scintillation counter. The GAD-Ab results were expressed by WHO standard unit (U/ml). A total of 224 healthy controls, 162 patients with type 1 diabetes mellitus(T1DM) and 210 patients with newly diagnosed type 2 diabetes (T2DM) were recruited. A total of 119 TI DM and healthy cases with gradually changing GAD-Ab levels were selected to compare the consistency of micro-plate RBA with conventional radioligand assay (RLA). Blood samples were obtained from the peripheral vein and finger tip in 32 healthy controls, 35 T1DM and 24 T2DM patients, and tested with micro-plate RBA and then compared with the conventional RLA to investigate the reliability of finger tip sampling. Linear correlation,student's t-test, variance analysis and receiver operating characteristic (ROC) curve were performed using SPSS 11.5. Results (1) The optimized conditions of micro-plate RBA included 2 μl serum incubated with3 ×104 counts/min 35S-GAD for 24 h under slow vibration, antigen-antibody compounds washed 10 times by 4℃ PBS buffer, and radioactivity counted with Optiphase Supermix scintillation liquid. (2)The intra-batch CV of the micro-plate RBA was 3.8%- 10.2%, and the inter-batch CV was 5.6%- 11.9%. The linearity analysis showed a good correlation when the GAD-Ab in serum samples ranged from 40.3 to 664 U/ml and the detection limit of measurement was 3.6 U/ml. The results from Diabetes Autoantibody Standardization Program (DASP) 2005 showed that the sensitivity and specificity for GAD-Ab were 78% (39 positive among 50 new-onset T1DM) and 98% (2 positive among 100 healthy controls). The results of GAD-Ab obtained with micro-plate RBA and RLA were closely correlated (r=0.915,P<0.001) with a high concordance level of 97.5% and a Kappa value of 0.95. (3)TI DM and T2DM patients showed higher positive rates for GAD-Ab than the healthy controls(46.9% and 5.2% vs 0.89% ,X2=123.5 and 10. 1 ,P <0.001 and <0.01, respectively). (4)The consistency of GAD-Ab measurement with RBA using finger tip blood and RLA measurement using venous blood was 96.7% (r =0.946,P <0.001, Kappa value: 0.905). Conclusions The micro-plate RBA of GAD-Ab has high sensitivity, specificity and reproducibility, and can be measured with finger tip blood sampling. It might be a better alternative for clinical practice.

RESUMEN
Summary: In order to confirm whether the mRNA levels of adiponectin in adipose tissue and mRNA levels of AdipoR1 in the skeletal muscles were correlated with the serum parameters of glucose and lipid metabolism and to clarify the regulation of adiponectin receptor gene expression in diabetic states, serum adiponectin, mRNA levels of adiponectin in adipose tissue and mRNA levels of AdipoR1 in the skeletal muscles were examined in type 2 diabetic rats. The model of type 2 diabetes was prepared by feeding high fat diet and injecting low dosage of streptozotocin (STZ). The diabetic rats were screened out by oral glucose tolerance test. One group of type 2 diabetic rats received rosiglitazone. The serum adiponectin concentration was detected by using ELISA and mRNA levels were examined by RT-PCR. The serum adiponectin levels and mRNA levels of adiponectin in adipose tissue of type 2 diabetic rats were significantly decreased as compared with the normal control rats (P<0.05, P<0.01 respectively). No siglificant changes were observed in the expression of adiponectin receptor 1 in the skeletal muscle of type 2 diabetic rats. The mRNA levels of adiponectin in adipose tissue were reversely correlated with serum insulin (r=-0.66, P<0.05), triglyceride (r=-0.58, P<0.05), cholesterol (r=-0.49, P<0.05), interleukin-6 (r=-0.49, P<0.05) and tumor necrosis factor (r=-0.43, P<0.05). The expression of adiponectin receptors was not altered in the skeletal muscle of Type 2 diabetic rats. The decreased serum adiponectin was caused by the decreased expression of adiponectin mRNA in adipose tissue rather than the adiponectin receptors in the skeletal muscle, which could be improved by rosiglitazone.
RESUMEN
AIM: To evaluate the pulmonary function in patients with type 2 diabetes mellitus in order to identify whether the lung is a target organ of chronic pathologic changes in diabetes mellitus. METHODS: Pulmonary ventilation function and diffusion capacity were studied in 107 patients with type 2 diabetes mellitus and 61 healthy subjects matched for age and sex. Glycosylated hemoglobin (HbA1c), urine albumin excretion rate (AER), fundus examination and nerve conduction velocity were included as parameters of glycemic control and diabetic microangiopathies. RESULTS: Pulmonary ventilation function was similar in type 2 diabetic group and the control. Compared with the control, carbon monoxide diffusion capacity (DLCO) and DLCO corrected by alveolar volume (DLCO/VA) were significantly lower in type 2 diabetic group (P<0.05). DLCO and DLCO/VA were inversely correlated with microangiopathy score (r: -0.291, -0.324, respectively, P<0.01). Furthermore, DLCO/VA was negatively correlated with age and duration of diabetes mellitus (r: -0.269, -0.236, respectively, P<0.05). CONCLUSIONS: Pulmonary ventilation function is normal in patients with type 2 diabetes mellitus, but their diffusion capacity is impaired. It suggests that the lung may also be the target organ of the chronic pathologic changes of diabetes mellitus.
RESUMEN
Objective To study the relationship between insulin resistance(IR) and dyslipidemia and nonalcoholic fatty liver disease(NAFLD) in type 2 diabetes mellitus(T2DM).Methods Seventy-two patients were divided into fatty liver group and non-fatty liver group.Blood lipid,blood glucose(BG),blood pressure,fasting and 2-hour serum insulin were measured.At the same time,HOMA-IR,body weight index(BMI),the waist hip ratio(WHR) were calculated.the diagnosis of the fatty liver was learned from the check according to an image.Results Compared with the non-fatty liver group,the average levels of TG,LDL-C,FIns,2hIns,HOMA-IR,BMI,WHR,alanine aminotransferase(ALT),?-glutamyl transpeptidase(?-GT),uric acid and diastolic pressure were significantly higher in fatty liver group(P0.05).Conclusion Compared with the non-fatty liver patients,T2DM patients complicated with NAFLD have more serious IR,dyslipidemia and obesity.It indicates that IR has a significant influence on the outbreak of the fatty liver;The NAFLD is probably one of components of metabolic syndrome.

Se realizó una investigación descriptiva, retrospectiva y de corte transversal con el objetivo de identificar las características clínicas de la diabetes mellitus tipo 2 en el municipio de Güines en el año 2002. El universo lo constituyeron 3 017 diabéticos tipo 2 registrados en el citado municipio en el año 2001 y la muestra 328 de estos casos, seleccionados a través de un muestreo complejo (estratificado en la primera etapa y por conglomerados en la segunda). Los resultados se procesaron estadísticamente (Programa SPSS, versión 10). La media de edad fue de 65,2 años. Existió malnutrición por exceso en 221 individuos (67,4 por ciento); 111 eran hipertensos; de ellos solo 32 (28,8 por ciento) estaban controlados. La toma fortuita de tensión arterial realizada durante la investigación detectó cifras normales en solo 45 (49,5 por ciento) personas. De 217 diabéticos no dispensarizados como hipertensos, 63 (29,1 por ciento) tenían cifras elevadas en la citada medición fortuita. Las complicaciones crónicas más frecuentes fueron la polineuropatía periférica, la cardiopatía isquémica y la retinopatía diabética con 85 (25,9 por ciento), 79 (24,1 por ciento) y 78 (23,8 por ciento) respectivamente; El control glucémico fue bueno o aceptable en 175 encuestados (53,0 por ciento) Existió alta frecuencia de diabéticos tipo 2 con descontrol glucémico entre los casos evaluados, así como subregistros en la información obtenida por historias clínicas ambulatorias, sobre todo en relación con complicaciones crónicas e hipertensión arterial(AU)
Retrospective descriptive cross-sectional research study was made to identify the clinical characteristics of diabetes mellitus type 2 in the municipality of Güines, Habana province, in the year 2002. The universe of study was made up of 3 017 type 2 diabetics, who had been registered in this municipality in 2001, whereas the sample was composed by 328 cases selected from a complex sampling process (stratified in the first stage and by conglomerates in the second phase). Results were statistically processed (Program SPSS, version 10). Mean age was 65,2 tears. Excessive malnutrition was found 221 individuals (67,4 percent), 111 were reported hypertensive but only 32 (28,8 percent) were under control. The sudden taking of blood pressure during the research detected normal rates in only 45 patients (49,5 percent). Of 217 diabetics who were not classified as hypertensive, 63(29,1 percent) showed raised blood pressure rates. The most frequent chronic complications were peripheral polyneuropathy, ischemic cardiopathy and diabetic retinopathy in 85 (25,9 percent), 79 (24,1 percent) and 78 (23,8 percent) patients respectively. Glucemia control was good or acceptable in 53 percent of the sample(175 surveyed). There was a high frequency of type 2 diabetics with no glucemic control among the evaluated cases and also incomplete registration as to chronic complications and blood hypertension in the information obtained from outpatient medical histories(AU)
