RESUMO
Hypoglycemia is the most common complication of the treatment for diabetes mellitus. Current studies suggest that recurrent hypoglycemia induces impaired awareness of hypoglycemia in diabetes by the failure of sympathetic nerve response or other mechanisms, which increases the risk of severe hypoglycemia and hypoglycemic fear in diabetics. Therefore, exploring the pathogenesis and preventive measures of impaired awareness of hypoglycemia is expected to provide new ideas for reducing severe hypoglycemia events and conducting subsequent studies.
RESUMO
Diabetic cardiomyopathy is a myocardial complication associated with abnormal glucose metabolism and dyslipidiaemia, which increases the risk of death and heart failure in diabetic patients. Mitochondrial dysfunction is involved in the occurrence and development of diabetic cardiomyopathy. Recent studies have confirmed that scavenging damaged mitochondria in cardiomyocytes through mitophagy can restore mitochondrial homeostasis, reduce oxidative stress and improve diabetic cardiomyopathy. Therefore, this article provides a comprehensive review of the mechanisms and characteristics of mitochondrial autophagy in diabetic cardiomyopathy. It aims to offer new insights and theoretical basis for the prevention and treatment of diabetic cardiomyopathy.
RESUMO
Objective To investigate the application value of urine microalbumin (mALB) ,retinol binding protein(RBP) and cys-tatin C(CysC) and their combined detection in early diagnosis of type 2 diabetic nephropathy(DN) .Methods Ninety-two inpatients with DN (DN group) and 90 people undergoing the physical examination(control group) in our hospital from June 2014 to Decem-ber 2015 were collected .Urine mALB ,RBP and CysC were detected in all subjects and detection results were analyzed statistically . Results The levels of urine mALB ,RBP and CysC in the DN group were significantly higher than those in the control group ,the differences all had statistical significance (P< 0 .05) .Among 3 indicators ,the positive rate of urine mALB for detecting DN was highest (94 .57% ) ,while which of 3-index combined detection was 97 .83% ,and significantly higher than that of single detection , the difference was statistically significant(P<0 .05) .The sensitivity ,specificity ,positive predictive value ,negative predictive value and Youden index of 3-index combined detection were all higher than those of single index .The ROC curve showed that AUC of u-rine mALB for diagnosing DN was 0 .732 ,the diagnostic cut-off value was 43 .58 mg/L ,AUC of urine RBP was 0 .685 ,the diagnos-tic cut-off value was 1 .47 mg/mL ,AUC of urine CysC was 0 .701 ,the diagnostic cut-off value was 1 .42 mg/L ,while AUC of com-bined detection was 0 .928 .Conclusion Urine mALB ,RBP and CysC are better indexes reflecting renal injury .Their combined de-tection will increase the positive rate ,sensitivity and specificity for diagnosing DN .So monitoring the levels of urine mALB ,RBP and CysC has an important significance to diagnosing the occurrence and development of DN early renal injury and prevention ,treat-ment and delaying progress of DN .
RESUMO
Objective To establish the quality control standards for Compound caulis Polygoni multiflori mixture .Meth-ods Caulis polygoni multiflori ,cortex alibiziae and schisand chinensis were identified by TLC ,total flavonoids were deter-mined by UV .Results Caulis polygoni multiflori ,cortex alibiziae and schisand chinensis could be detected by TLC .A better linear relationship between concentration and absorbance in the range of 9 .12~27 .36 μg/ml .The linear regression equation was A=0 .034 55 C-0 .110 34 (r=0 .999 2) ,The average recovery of emodin was 101 .0% (RSD=1 .58% ) .Conclusion The method is simple ,quick ,accurate and sensitive ,which could be used as a quantitative analysis method for this preparation .
RESUMO
Objective:To observe the therapeutic effect ofexternal application ofChinese herbal medicine film plus acupoint-injection on breast hyperplasia.Methods:The 120 cases ofbreast hyperplasia with syndrome ofthe liver failing to maintain the normal flow ofqi were randomly divided into treatment group(40cases) which was treated by external application ofChinese herbal medicine film plus acupoint-injection, acupoint-injection group(40 cases) and control group(40cases).The changes ofsymptoms and signs, level ofserum sexual hormone and color doppler ultrasound analysis ofthree group were observed for comparison.Results:After 1 course oftreatment, the total effective rate oftreatment group was obviously higher than that ofcontrol group(P0.05).After 2 courses oftreatment, the total effective rate oftreatment group and acupoint-injection group was obviously higher than that ofcontrol group(P
RESUMO
Objective To observe the effect of pigplacenta ins tead of Ziheche (P lacenta Hominis) for the treatment of senile dementia. Methods Seventy Kunming mice were divided into blank group, model group, pos itive control group, Zih eche low and high dosage groups, and pigplacenta low and high dosage grou ps, wi th 10 in each. The senile dementia models were established with the D-Galactose subcutaneous injection. The blank group was not administered any medicines. The model group was prescribed normal saline instead of the tested medicine; the pos itive control group was given Naofukang by gavage; the Zih eche low and high dosage groups were given 2g/kg and 4g/kg Ziheche respectivel y by gavage; while the pigplacenta low and high dosage groups were treated wi th p igplacenta 4g/kg and 8g/kg respectively by gavage. After treatment for 6 week s, the behavior experimental dark-avoiding test and step-down test were applied to test the effect of the medicines on the learning memory of mice, and acetylchol inesterase and monoamine levels in brain tissues. Results There was no s ignificant difference between the effect of pigplacenta and Ziheche in resi stin g senile dementia. In the latency of dark-avoiding test, the effect of high d osa ge of pigplacenta was significantly better than that of Ziheche (P
