ObjectiveTo explore the relationship between sleep quality and glucose level,diabetic complications in elderly type 2 diabetes mellitus.Methods A total of 130 hospitalized elderly type 2 diabetes in our hospital were included in the study. Questionnaires and other related clinical data were collected within one week after admission.Patients were divided into two groups:poor-sleeper group and good-sleeper group according to Pittsburgh Sleep Quality Index(PSQI).ResultsSixty percent (78/130) of these patients were poor sleepers. The following parameters differed in the two groups:the duration of diabetes [ (7.9 ± 1.8 ) years vs ( 7.2 ± 1.5 ) years,t =2.318 ],systolic blood pressure [ ( 148 ± 30 ) mm Hg ( 1 mm Hg =0.133 kPa) vs ( 138 ± 23 ) mm Hg,t =2.037 ],fasting plasma glucose (FPG) [ ( 10.7 ± 2.2) mmol/Lvs ( 9.8±1.9)mmol/L,t =2.410],hemoglobin A1c (HbA1c) [(8.6 ±2.2)% vs (7.8±2.1 ) %,t =2.068],high-sensitive C-reactive protein (hs-CRP) [ (5.27 ± 2.34) mg/L vs (4.44 ± 1.76)mg/L,t =2.179 ],ratio of diabetic complications ( 61% vs 32%,x2 = 4.257 ),percentage of depression ( 20% vs 8%,x2 =3.722 ),score of life quality [ ( 98 ± 19 ) scores vs ( 89 ± 13 ) scores,t = 2.980 ],and proportion of patients treated with insulin (32% vs 12%,x2 =4.489). All the above parameters were significantly higher in poor-sleeper group than the good-sleeper group (all P value< 0.05 ). Multiple correlation analysis showed that the factors affecting sleep quality were FPG,HbA1c,duration of diabetes,diabetic complications,depression,life quality and insulin application (r =0.213,0.257,0.223,0.335,0.422,0.3451,0.231,respectively ; all P value < 0.05 ).By multivariate logistic regression analysis,the followings were found:FPG (β =1.29,P < 0.05 ) and PSQI (β =1.07,P < 0.05 ) were found to be correlated with HbA1c.With increasing of PSQI,FPG,HbA1c,diabetic complications and life quality were changed significantly( all P value < 0.05 ).The indcpcndcnt risk factors of diabetic complications were duration of diabetes ( OR = 1.32,95% CI 1.01-2.01 ),HbA1c ( OR =2.01,95% CI 1.63-2.67 ),hs-CRP( OR =1.12,95% CI 1.08-1.21 ) and PSQI ( OR =1.71,95% CI 1.58-2.02).ConclusionsElderly type 2 diabetes mellitus are usually poor sleepers. Sleep quality probably affects blood glucoseregulation, and is closely correlated with the occurrence of complications.In addition,poor sleep quality results in poor life quality.

Background Pesticides like organophosphorus and pyrethroids are extensively utilized, and associated potential human health risks arising from multi-route exposure, including environmental sources and dietary intake, cannot be overlooked. Conducting human exposure studies using pesticide exposure biomarkers is essential for an objective evaluation of human pesticide exposure levels. Objective To develop a rapid and precise liquid chromatography-tandem mass spectrometry method for the detection of 12 pesticide metabolites in urine, including 5 metabolites of organophosphorus pesticide, 4 metabolites of pyrethroid pesticide, 2 metabolites of herbicides, and 1 metabolite of insecticide. Methods After overnight enzymatic hydrolysis, urine samples were subjected to extraction and purification using Oasis HLB 96-well solid-phase extraction. Subsequently, the samples were analyzed by liquid chromatography-tandem mass spectrometry and quantified using the isotope internal standard method. The developed method was employed to analyze 143 urine samples from a general population to assess its effectiveness and to evaluate pesticide exposure levels. Results All 12 target compounds exhibited good linear ranges, with their correlation coefficients of calibration curves exceeding 0.999. The limits of detection (LOD) ranged from 0.02 to 0.19 μg·L−1, while the limits of quantitation (LOQ) ranged from 0.06 to 0.27 μg·L−1. The recoveries at three spiked levels ranged from 84% to 112%, and the inter- and intra- day precisions of targeted analystes were 0.43%-9.6% and 1.6%-9.7% respectively. Using this method, 143 urine samples from residents in Jiangsu region were analyzed, and 11 pesticides were detected except N,N-diethyl-m-toluamide (DEET). Conclusion The established method of solid-phase extraction combined with liquid chromatography-tandem mass spectrometry has the characteristics of low detection limit, good repeatability, and high throughput, which is suitable for quantitative detection of selected 12 pesticides in large batches of human urine samples, and provides technical support for pesticide internal exposure monitoring and health risk assessment.

Ulcerative colitis (UC) is a commonly seen digestive system disease with unclear pathogenesis. The condition is complex and variable, often chronic, and has a long treatment period with no specific cure. Currently, the treatment of UC often involves the use of corticosteroids, aminosalicylates, and biologics in western medicine, which provide fast-acting and definite efficacy in the short term. However, with prolonged medication, some patients may develop drug resistance and worsening of the disease, leading to the occurrence of colon cancer. Research has found that oxidative stress is one of the important pathogenic factors in UC and influences its onset and development. Oxidative stress is a state of imbalance between oxidative products and the antioxidant system in the body, characterized by overexpression of oxidative products such as malondialdehyde (MDA), reactive oxygen species (ROS), nitric oxide (NO), or deficiency of antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), and glutathione (GSH). It is worth noting that traditional Chinese medicine (TCM), as a unique characteristic medicine of China, has achieved significant efficacy in the treatment of UC. Studies have shown that TCM effectively inhibits the occurrence of UC by suppressing the accumulation of metabolites and antagonizes the development of UC by enhancing the antioxidant system. Therefore, using TCM to regulate the oxidative balance as a diagnostic and therapeutic approach may be a new method and direction for the treatment of UC in the future. Based on the above research, this article summarized the mechanisms of key pathogenic proteins in oxidative stress and the occurrence and development of UC, and compiled the effective ingredients of Chinese medicine, single drugs, prescriptions, and acupuncture and moxibustion in regulating upstream and downstream target proteins of oxidative stress. These interventions can reduce pathological damage to the intestinal mucosa, lower the colon injury index, enrich the intestinal microbiota, increase colon length, and improve clinical symptoms of UC. The article is expected to expand the application of TCM in the treatment of UC and provide a reliable scientific theoretical basis.
