RESUMO

BACKGROUND Type 2 diabetes mellitus is a global public health problem. Prediabetes may be reversed by weight loss, diet, and lifestyle changes. However, without intervention, between 30-50% of individuals with prediabetes develop type 2 diabetes. This retrospective population study was conducted to develop a predictive model of prediabetes and incident type 2 diabetes mellitus using data from 2004 to 2015 from the DRYAD Japanese hospital database. MATERIAL AND METHODS A retrospective longitudinal population study was conducted using the DRYAD database from Murakami Memorial Hospital, Gifu, Japan, to construct a predictive model for prediabetes and incident type 2 diabetes mellitus in the population. Univariate analysis and multivariate analysis were performed to identify the variables that were associated with prediabetes. These variables were used to construct (75% samples) and verify (25% samples) the predictive model. RESULTS From 2004 to 2015, a total of 11,113 cases were identified. Multivariate logistic regression analysis included the six variables of age, waist circumference, smoking history, the presence of fatty liver, fasting blood glucose (FBG), and glycated hemoglobin (HbA1c) level. Data were used to construct (75% samples) and verify (25% samples) in a predictive model. The area under the receiver operating characteristic (ROC) curve (AUC) of the predictive model was 0.87 (0.85-0.89) in the training cohort and 0.87 (0.86-0.90) in the validation cohort. CONCLUSIONS A prognostic model based on six variables was predictive for incident type 2 diabetes mellitus and prediabetes in a healthy population in Japan.

RESUMO

BACKGROUND: Acute kidney injury (AKI) is the most common cause of organ failure in multiple organ dysfunction syndrome (MODS) and is associated with increased mortality. This study aimed at determining the efficacy of sequential organ failure assessment (SOFA), and acute physiology and chronic health evaluation II (APACHE-II) scoring systems in assessing the prognosis of critically ill patients with AKI undergoing CRRT. METHODS: The predictive value of SOFA and APACHE-II scores for 28- and 90-d mortality in patients with AKI undergoing continuous renal replacement therapy (CRRT) were determined by multivariate analysis, sensitivity analysis, and curve-fitting analysis. RESULTS: A total of 836 cases were included in this study. Multivariate Cox logistic regression analysis showed that SOFA scores were associated with 28- and 90-d mortality in patients with AKI undergoing CRRT. The adjusted HR of SOFA for28-d mortality were 1.18 (1.14, 1.21), 1.24 (1.18, 1.31), and 1.19 (1.13, 1.24) in the three models, respectively, and the adjusted HR of SOFA for 90-d mortality was 1.12 (1.09, 1.16), 1.15 (1.10, 1.19), and 1.15 (1.10, 1.19), respectively. The subgroup analysis showed that the SOFA score was associated with 28-d and 90-d mortality in patients with AKI undergoing CRRT. APACHE-II score was not associated with 28- and 90-d mortality patients with AKI undergoing CRRT. Curve fitting analysis showed that SOFA scores increased had a higher prediction accuracy for 28- and 90-d than APACHE-II. CONCLUSIONS: The SOFA score showed a higher accuracy of mortality prediction in critically ill patients with AKI undergoing CRRT than the APACHE-II score.

RESUMO

Background: Acute kidney injury (AKI) requiring continuous renal replacement therapy (CRRT) is a fatal and common clinical disorder in critically ill patients. Recent studies have shown that the relationship between BMI and the outcome of patients with AKI undergoing CRRT is conflicting. Methods: A retrospective cohort study based on data reuse. Univariate analysis, multi-factor regression analysis and subgroup analyses were used to explore the association of the BMI with the 28-days mortality risk in patients with AKI undergoing CRRT. Results: From January 2009 to September 2016, a total of 1120 cases met the inclusion criteria and were enrolled in this study. The univariate analysis showed that BMI was associated with 28-days mortality of patients with AKI undergoing CRRT, its HR value was 0.98 (0.96, 0.99). The multi-factor regression analysis showed that BMI was not associated with 28-days mortality of patients with AKI undergoing CRRT in the four models, the adjusted HR value of four models were 1.00 (0.96, 1.04), 1.01 (0.97, 1.04), 1.00 (0.96, 1.04) and 1.00 (0.96, 1.04), respectively. The subgroups analyses showed that the BMI was a risk factor of the 28-days mortality in patients with AKI undergoing CRRT when GFR ≥30 mL/min, its HR value was 1.04 (1.01, 1.09). Conclusion: Higher BMI was not a protective risk of 28-day mortality in patients with AKI undergoing CRRT. Especially, when GFR ≥30 mL/min, higher BMI increased the risk of the 28-day mortality rate in patients with AKI undergoing CRRT.

RESUMO

OBJECTIVE: To investigate the improving effect of Litchi Seed Aqueous Extracts on learning and memory obstacles model and its mechanism. METHODS: The learning and memory obstacles model was incluced by subcutoneous injection of D-galactose (500 mg/kg) for 8 weeks. The model group and treatment groups were given huperzine A (0.4 mg/kg) and Litchi Seed Aqueous Extracts (15,60 g/kg) respectively for 4 weeks by ig at the 5th week. After huperzine A and Litchi Seed Aqueous Extracts treatment for 4 weeks, water maze test was used to determine the ability of mice's spatial learning and memory. The contents of advanced glycation end products (AGEs) in serum, the content of nitric oxide (NO) and acetylcholine (Ach), the activity of nitric oxide synthase (NOS) and acetylcholinesterase (AchE) in the brain tissue were detected. RESULTS: Litchi Seed Aqueous Extracts significantly ameliorated the learning and memory ability in mice, decreased the level of AGEs in serum, and reduced the content of NO and activity of NOS in brain tissues. No significantly influence was observed for the Ach and Ach-E in brain tissues. CONCLUSION: Litchi Seed Aqueous Extracts possesses improving the learning and memory effects on the model mice induced by D-galactose, which may be related to inhibiting too much AGEs and NO formation and reducing damage in the brain cells.

RESUMO

Introduction: Early identification of AKI was always considered to improve patients' prognosis. Some studies found that AKI early warning tools didn't affect patients' prognosis. Therefore, additional studies were necessary to explore the reasons. Methods: This study was a secondary analysis of a multicenter randomized controlled trial that found electronic health record warnings for AKI did not influence patients' prognoses. Univariate, multivariate, subgroup, curve fitting, and threshold effect analysis were used to explore the association between AKI warnings detected by attending physicians and the patient's prognosis. Results: A total of 6,030 AKI patients were included in the study. The patients were classified into two groups based on the rate of AKI alerts detected by attending physicians: the partial group (n = 5,377), and the complete group (n = 653). In comparison to the partial group, the complete group significantly decreased 14-day AKI progression, 14-day dialysis, and 14-day mortality, with adjusted ORs of 0.48 (0.33, 0.70), 0.26 (0.09, 0.77), and 0.53 (0.33, 0.84) respectively, and the complete group significantly improve the discharge to home, with an OR value of 1.50 (1.21, 1.87). When the rate of AKI alerts detected by the attending physicians as a continuity variable, we found that the rate of alerts seen by attending physicians was associated with 14-day mortality and the discharge to home, with adjusted ORs of 1.76 (1.11, 2.81) and 1.42 (1.13, 1.80). The sensitivity analysis, curve-fitting analysis, and threshold effect analysis also showed that the rate of alert seen by the attending physician was correlated with the patient's prognosis. Conclusion: The rate of AKI alert detection by attending physician were related to the patient's prognosis. The higher the rate of AKI alert detection by attending physicians, the better the prognosis of patients with AKI.

RESUMO

OBJECTIVE: To study the effects of berberine on hypertensive renal injury model in rats fed by enriched high fat-salt-fructose diet . METHODS: hypertensive renal injury model was esteblished by feeding enriched high fat-salt-fructose diet for 8 weeks. On the basis of animal blood pressure, hypertensive rats were randomly divided into model group (10 rats, distilled water), captopril group (10 rats,25 mg/kg), berberine high dose group (10 rats, 300 mg/kg) and low dose group (10 rats, 100 mg/kg). These rats were fed by enriched high fat-salt-fructose diet and treated by intragastric administration with drugs for 4 weeks. And normal control group (10 rats) was set Blood pressure was determined at 0, 4, 8, 10, 12 weekend,and after 4 weeks of drugs treatment, getting urine to determine urine protein, taking blood serum to determine blood urea nitrogen, serum creatinine,GHb,MDA and activity of SOD. The content of H2O2 and GSH-Px and activity of CAT in kidney tissues were determined also. RESULTS: Compared with normal control group, blood pressure, urine protein, blood urea nitrogen, serum creatinine and MDA and GHb in serum of model rats obviously increased (P < 0.01), the activity of SOD decreased (P < 0.01), higher content of H2O2 and lower content of GSH-Px and activity of CAT (P < 0.01) in the kidney tissues. Treated with berberine for 4 weeks, elevated blood pressure and heightened levels of urine protein, blood urea nitrogen and serum creatinine in model rats were depressed significantly (P < 0.01), and elevated the activity of SOD, lowed the levels of MDA and GHb in blood serum (P < 0.01). At the same time, berberine increased the activities of GSH-Px and CAT (P < 0.01) and slightly lowed the content of H2O2 in the kidney tissues. CONCLUSION: Berberine has protecting effects on the hypertensive renal impairment model rats fed by enriched high fat-salt-fructose diet, which are concerned with elevated antioxidant capability in body and kidney tissues.

RESUMO

No matter in or outside hospital, the success rate of cardiopulmonary resuscitation (CPR) is very low. The sign of successful CPR is the recovery of spontaneous circulation. The premise of the recovery of spontaneous circulation is the recovery and maintenance of sinus rhythm, but there is still no related research.We aim to study the factors for the recovery and maintenance time of sinus rhythm in patients with CPR.A single-center retrospective case-control study.Ethical review was obtained (ethical approval number: 20180031).The second affiliated hospital of Xi'an Jiaotong University, Xi'an Shaanxi, China.From January 2011 to December 2016, totally 344 cases met the inclusion and exclusion criteria, sinus rhythm recovered group (SR group) (n = 130 cases), sinus rhythm unrecovered group (SUR group) (n = 214 cases).The multivariate logistic regression analysis showed that red blood cell counts (OR = 1.30, 95% CI:1.04-1.63, P = .02), rescue time (OR = 0.95, 95% CI:0.94-0.97, P <.001), the usage of norepinephrine (OR = 2.14, 95% CI:1.06-4.35, P = .04) were important factor for the recovery of sinus rhythm in patients with CPR. Multivariate linear regression analysis showed that the dosage of epinephrine, the usage of naloxone and diagnosis were important factors for maintenance time of sinus rhythm after resuscitation, P <.05. The rescue time had high accuracy to predict the recovery of sinus rhythm, the area under the receiver operator characteristic (ROC) curve (AUC) was 0.84 (0.80, 0.88), sensitivity and specificity are respectively 71.54% and 93.46%.Red blood cell counts, the rescue time and the usage of norepinephrine might be important factors for the recovery of sinus rhythm, and the dosage of epinephrine, the usage of naloxone and the diagnosis might be important factors for the maintenance time of sinus rhythm in patients with CPR.

RESUMO

OBJECTIVE: To study the pathological changes of blood glucose, serum lipid, insulin resistance, liver function, liver cell denaturalization of total glucosides of paeony on nonalcoholic fatty liver rats caused by insulin resistance and discuss the acting mechanism. METHOD: Adult SD rats were maintained on high-fat-sugar-salt diet for 56 days. In the 57th day, their fasting blood glucose (FBG) and 2-hours blood glucose after oral glucose tolerance test (OGTT-2 hBG) were mensurated, according to which and the weight the rats were divided randomly into nonalcoholic fatty liver model group, metformin group (0.2 g x kg(-1)) and total glucosides of paeony group (high dosage 0.15 g x kg(-1), low dosage 0.05 g x kg(-1)). All the rats were still administered the same diet and given different drugs by intragastric administration for 28 days. In the 29th day, all of them were killed and the blood was sampled to measure the levels of blood glucose [FBG, OGTT-2 hBG, fasting insulin (Fins)] and serum lipid [free fatty acids (FFA), triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C)], then the HOMA insulin resistance index (HOMA-IRI, fasting glucosexinsulin) and insulin sensitivity index (ISI) were counted. The activities of aspartate aminotransferase (AST), alanine aminotransferase (ALT), cholinesterase (ChE), superoxide dismutase (SOD) and the contents of malondialdehyde (MDA) were measured also. Livers were weighed and collected to be observed the pathological changes. RESULT: Compared with normal group, in nonalcoholic fatty liver model group the levels of Fins and IRI were increased obviously (P < 0.01), ISI were decreased (P < 0.01), FFA, TG, TC, LDL-C were increased (P < 0.01), HDL-C were decreased (P < 0.05); the content of MDA were increased (P < 0.05), the activities of SOD were decreased (P < 0.01); AST, ALT and ChE were increased (P < 0.05, or P < 0.01), the pathological changes of liver fat were severe (P < 0.01). In glucosides of paeony group and metformin group, hyperinsulinaemia and insulin resistence were resisted (P < 0.05, or P < 0.01); the levels of FFA, TG, TC, LDL-C were decreased and HDL-C were increased (P < 0.05, or P < 0.01); the activities of AST, ALT, ChE were decreased (P < 0.05, or P < 0.01) and SOD were increased (P < 0.01). The contents of MDA were decreased (P < 0.05). The levels of FBG and 2 hBG in metformin group were decreased but in total glucosides of paeony group were not decreased obviously. CONCLUSION: Total glucosides of paeony may protect liver function and modulate serum lipid for the fatty liver rats caused by insulin resistance, and its action mechanism may be concerned with enhancing insulin sensitivity and antioxidative ability, decreasing serum lipid.

RESUMO

OBJECTIVE: To observe the improvement effects of puerarin on glycated brain damages in rat model induced by D-galactose. METHOD: The model rats of protein glycation were induced by intraperitoneal administration of D-galactose (150 mg x kg(-1) x d(-1)) for 8 weeks, and all rats were treated with puerarin (high dose 300 mg x kg(-1), middle dose 150 mg x kg(-1), low dose 75 mg x kg(-1)) for 6 weeks. The activity of aldose reductase in red blood cells, the amount of glycated products (fructosamine in serum, glycohaemoglobin, advanced glycation end-products) and AGEs in brain tissue, calcium ion in brain cells were measured. Moreover, mitochondria in brain hippocampus cells were observed under electronic microscope. RESULT: High dose and middle dose of puerarin can decrease the activity of aldose reductase in red blood cells (P < 0.01), and inhibit the formation of glycation products significantly in model rats induced by D-galactose (P < 0.01). Also, puerarin can decrease the content of AGEs in brain and the level of calcium ions in brain cells (P < 0.05, P < 0.01), and decrease lesions degree in mitochondria in brain hippocampus cells. CONCLUSION: Puerarin can produce the protective effects on glycated brain damages through inhibiting the glycation reaction in rats induced by D-galactose.

RESUMO

AIM: To measure the effect of addition of heparin to adriamycin (ADM) on cell proliferation and apoptosis in CNE2 cells and investigate the possible molecular mechanisms of heparin and ADM interactions. METHODS: Cell viability and cell cycle were determined by MTT assay and flow cytometry. Apoptosis was evaluated by terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) and agarose gel electrophoresis. The expression of Bax, Bcl-2, p53, and p21 was examined by Western blot. RESULTS: ADM (5 mg/L) alone inhibited the growth of CNE2 cells, which was magnified when heparin was added. ADM elicited typical apoptotic morphologic changes. Compared with ADM or heparin alone, ADM plus heparin obviously enhanced the number of TUNEL positive cells from 12.6 % 1.1 % to 65.7 % 1.3 %, and the DNA ladder was more clearly observed. After exposure to different concentrations of heparin (with or without ADM) for 24 h, CNE2 cells were accumulated in G0/G1 phase. There was a decrease in the number of cells in S phase by the combined heparin and ADM treatment compared to heparin or ADM alone. The ratio of Bax/Bcl-2 was elevated, and p53 and p21 mRNA were over-expression. CONCLUSION: Heparin and ADM appear to interact in a synergistic manner, which may be related to the over-expression of p53 and p21 mRNA and the elevated ratio of Bax/Bcl-2 mRNA.
