  • 简介:AbstractBackground:Vitamin D deficiency has been reported to be associated with diabetic microvascular complications, but previous studies have only focused on the relationship between vitamin D and specific complications. Therefore, we aimed to explore the relationship between vitamin D level and diabetic microvascular complications in general, including diabetic retinopathy (DR), diabetic nephropathy (DN), and diabetic peripheral neuropathy (DPN).Methods:This was a cross-sectional study of 815 patients with type 2 diabetes mellitus (T2DM). Clinical information and laboratory results were collected from the medical records. The relationship between vitamin D and the three diabetic microvascular complications was investigated.Results:The serum 25-hydroxyvitamin D (25 [OH] D) level of patients with DPN and/or DN was significantly lower than that of T2DM patients without any microvascular complications (P < 0.01). Univariate analysis showed that the 25 (OH) D level was related to DPN and DN, but not DR. After adjustment, the 25 (OH) D level was confirmed to be an independent protective factor for DPN (odds ratio [OR]: 0.968, P = 0.004]) and DN (OR: 0.962, P = 0.006). The prevalence of DPN and DN increased significantly as the serum 25 (OH) D levels decreased. Furthermore, patients with both DPN and DN had the lowest concentration of serum 25 (OH) D (P < 0.001), and the prevalence of macroalbuminuria increased more abruptly than that of microalbuminuria across the 25 (OH) D tertiles. Among the patients with vitamin D insufficiency, those with DPN presented more comorbid macroalbuminuria than those without DPN (15.32% vs. 4.91%; P = 0.001).Conclusions:Vitamin D deficiency is independently associated with higher risk of DPN and DN, but not DR, in T2DM patients. Further, it may be a potential predictor for both the occurrence and severity of DPN and DN.

  • 简介:AbstractBackground:Fourier transform infrared (FTIR) spectroscopy technique has not been used as a diagnostic tool for diabetes in clinical practice. This study was linked to structural changes in hemoglobin (Hb) in type 2 diabetes patients at higher levels of HbA1C using FTIR spectroscopy.Methods:Fifty-three diabetic patients from the Bahawal Victoria Hospital, Bahawalpur, Pakistan were categorized as group A (6% < HbA1C < 7%; n = 25) and group B (HbA1C ≥9%; n = 28). Another group (group N) of twenty blood samples was taken from healthy people from the Islamia University Bahawalpur, Pakistan. Data from all groups were collected from January 1, 2018 to March 31, 2019. The structure of Hb was studied by FTIR spectroscopy and impact of glucose on the fine structure of HbA1C was estimated.Results:Hb secondary structure erythrocyte parameters were altered by changing glucose concentrations. From FTIR spectra of all three groups it was found that Hb structure was slightly altered in group A, but significantly changed in group B (P < 0.05). There was an increase in β-sheet structure and a reduction in α-helix structure at elevated levels of HbA1C (group B) in type 2 diabetes.Conclusion:We suggest that higher level of glycation reflected by increased HbA1C might be a contributing factor to structural changes in Hb in type 2 diabetic patients. FTIR spectroscopy can be a novel technique to find pathogenesis in type 2 diabetes.

  • 简介:AbstractObjective:The objective of this study was to investigate the expression levels of microRNA-141-5p(miRNA-141-5p), MAPK1 and neutrophil elastase in patients with and without preeclampsia (PE), and the relationship between miRNA-141-5p and MAPK1 with respect to the secretion of elastase by neutrophils in patients with PE.Methods:Thirty patients with PE and 30 healthy pregnant (HP) women were recruited from The Second Hospital of Shanxi Medical University, Taiyuan, China, between February 2017 and July 2018. Neutrophils were isolated from 8 mL peripheral blood samples and cultured. We recorded neutrophil count and morphology during culture. Apoptosis was detected by flow cytometry in different groups at 0, 24, and 48 h. The expression levels of elastase were detected in neutrophils by enzyme-linked immunosorbent assay, whereas the expression levels of miRNA-141-5p in peripheral blood neutrophils were detected by real-time polymerase chain reaction. We used TargetScanHuman Release 7.2 to analyze the target genes of miRNA-141-5p. The expression of MAPK1 in peripheral blood neutrophils was detected by western blotting. Data were analyzed by SPSS version 21.0 software, and comparisons between groups were carried out with the Student t test.Results:There was no significant difference between the PE and HP groups (P > 0.050) with regard to age or body mass index. The weight of newborns in the PE group (2846.00 ± 600.00 g) was significantly lower than that in the HP group (3055.00 ± 230.68 g). The number of neutrophilic granulocytes(NGs) in blood samples from the PE group was significantly higher than that in the HP group (P = 0.003). There was no significant difference between the groups with regard to morphology. Apoptosis in the PE group was delayed when compared with the HP group at different time points. The P value of apoptosis in the PE and HP groups were respectively 0.790, < 0.001 and 0.030 at 0 h, 24 h and 48 h. The expression levels of miRNA-141-5p in the PE group were significantly lower than those in the HP group (P < 0.050). The expression levels of MAPK1 in neutrophils from the PE group were significantly higher than those in the HP group (P < 0.050) by western blot. The expression levels of elastase in neutrophils from the PE group were significantly higher than those in the HP group (P < 0.050). Furthermore, the number of NGs in peripheral blood from the PE group was higher than that of the HP group; however, the levels of apoptosis were lower. The expression levels of miRNA-141-5p in NGs decreased, the expression of MAPK1 increased, and the secretion of neutrophil elastase in the NG medium increased in the PE group than those in the HP group.Conclusion:Collectively, our analysis suggested that miRNA-141-5p may be involved in the pathogenesis of PE by regulating the MAPK1 signaling pathway to activate neutrophils and increase the secretion of elastase.

  • 简介:AbstractImportance:Pediatric palliative care (PPC) is an interdisciplinary collaboration that focuses on the prevention and relief of patient suffering. PPC has emerged as a critical field of medical expertise and practice. However, no information is available regarding the progress of PPC in the Chinese mainland.Objective:This study investigated the geographic distribution, team structure, and services of PPC teams in the Chinese mainland. It also investigated the level of understanding and implementation among pediatric oncologists regarding PPC.Methods:The PPC subspecialty group of the Pediatrics Society of the Chinese Medical Association included 45 PPC teams. The team structure and services were investigated using questionnaires mailed to the team leader of each PPC team. In addition, we sent questionnaires regarding the level of PPC understanding and implementation of PPC practices to 170 pediatric oncologists in 11 hospitals.Results:The geographical distribution of PPC teams is uneven in China. Most PPC teams are concentrated in the eastern provincial capital of China. Most PPC teams had limited staff and services. The level of PPC understanding was considerably limited across all demographics; most pediatric oncologists reported "some understanding" (n =71, 41.8%) or "poor understanding" (n = 50, 29.4%). Only 62.9% of pediatric oncologists had experience providing advice to family members regarding PPC matters.Interpretation:China is currently experiencing a critical shortage of PPC resources. Most pediatric oncologists had a limited understanding of PPC and reported limited practical implementation of PPC, which leads to underutilization of PPC resources.

  • 简介:AbstractBackground:Our aim was to evaluate the sensitivity and specificity of the automated computer-based Alberta Stroke Program Early CT Score (e-ASPECTS) for acute stroke patients and compare the result with physicians at different levels.Methods:In our center, e-ASPECTS and 9 physicians at different levels retrospectively and blindly assessed baseline computed tomography (CT) images of 55 patients. Sensitivity, specificity, receiver-operating characteristic curves, Bland-Altman plots with mean score error, and Matthews correlation coefficients were calculated. Comparisons were made between the scores by physicians and e-ASPECTS with diffusion-weighted imaging (DWI) being the ground truth. Two methods for clustered data were used to estimate sensitivity and specificity in the region-based analysis.Results:In total, 1100 (55 patients × 20 regions per patient) ASPECTS regions were scored. In the region-based analysis, sensitivity of e-ASPECTS was better than junior doctors and residents (0.576 vs 0.165 and 0.111, p < 0.05) but inferior to senior doctors (0.576 vs 0.617). Specificity was lower than junior doctors and residents (0.883 vs 0.971 and 0.914) but higher than senior doctors (0.883 vs 0.809, p < 0.05). E-ASPECTS had the best Matthews correlation coefficient of 0.529, compared to senior doctors, junior doctors, and residents (0.463, 0.251, and 0.087, respectively).Conclusions:e-ASPECTS showed a similar performance to that of senior physicians in the assessment of brain CT of acute ischemic stroke patients with the Alberta Stroke Program Early CT score method.
