Objective: To analyze the chemical constituents of Shanxiangyuanye (Turpiniae Folium) through liquid chromatography-tandem mass spectrometry (LC-MS/MS) method, and to evaluate their anti-oxidant, hypoglycemic, and anti-glycation activities related to diabetic complications. Methods: The supernatant of Shanxiangyuanye (Turpiniae Folium) (TFS), obtained following water extraction and alcohol precipitation, was analyzed by LC-MS/MS. Antioxidant activity of TFS in vitro was evaluated using three experimental approaches: the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assay, the 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS+) radical cation decolorization assay, and the hydroxyl (·OH) radical scavenging assay. To comprehensively evaluate hypoglycemic potential, α-glucosidase inhibition was measured to analyze in vitro hypoglycemic activity. Subsequently, in vitro models were developed to examine anti-glycation activity through the bovine serum albumin (BSA)-fructose (Fru), BSA-methylglyoxal (MGO), BSA-glyoxal (GO), and D-arginine (Arg)-MGO systems, with particular attention to the inhibitory effects of TFS. Furthermore, the concentrations of fructosamine, protein carbonyls, sulfhydryl groups, and β-amyloid in the glycation solution were quantified using the BSA-Fru model following 7-d of incubation at 37 °C. Results: Using LC-MS/MS analysis in both positive and negative ion modes, we identified 750 chemical components in TFS, primarily including organic acids, amino acids, and their derivatives. In vitro activity studies demonstrated that TFS exhibited remarkable free radical scavenging capacity, with half-maximal inhibitory concentrations (IC50) of 0.47, 1.56, and 0.36 mg/mL against DPPH, ABTS+, and ·OH radicals, respectively. Regarding hypoglycemic activity, TFS dose-dependently inhibited α-glucosidase activity (IC50 = 0.21 mg/mL), displaying comparable efficacy to the clinical drug acarbose (IC50 = 0.23 mg/mL). Notably, TFS intervened in the glycation process: IC50 values were 0.22, 1.91 – 4.96, and 4.09 mg/mL in the BSA-Fru, BSA-MGO/GO, and Arg-MGO models, respectively, with the most prominent inhibitory effects observed in the BSA-Fru model. Furthermore, although TFS may not effectively preserve thiol groups in BSA or reduce thiol oxidation during glycation, it significantly reduces fructosamine levels (in a dose-dependent manner), decreases β-amyloid formation, and inhibits protein carbonylation (P < 0.000 1). Conclusion The findings demonstrate that TFS exhibits a complex chemical composition with potent antioxidant, hypoglycemic, and anti-glycation activities. These results provide compelling scientific evidence supporting TFS’s potential as a natural adjuvant for diabetes prevention and complication management, while laying a solid foundation for its applications in functional food development and adjunctive antidiabetic therapeutics.

Objective To explore the potential categories of fatigue trajectory in patients with diabetic peripheral neuropathy and analyze the influencing factors.Methods Convenience sampling method was used to select 426 patients with diabetic peripheral neuropathy who were hospitalized in a tertiary hospital in Jiangsu Province from April 2022 to April 2023.General information and disease related data of the patients were collected,and the Chinese version of Multi-dimensional Fatigue Scale,Pittsburgh Sleep Quality Index Scale,Social support Rating Scale,pain number rating scale and Tampa scale of kinetophobia were used to investigate at discharge(T1).The Chinese version of multi-dimensional fatigue scale was used to investigate 3 months after discharge(T2),6 months after discharge(T3),and 12 months after discharge(T4).A mixed growth model was used to identify the potential categories of fatigue trajectory and logistic regression were employed to analyze the influencing factors of fatigue.Results 414 patients finished the study.Three categories of fatigue trajectory in the patients with diabetic peripheral neuropathy were identified:significantly increasing group(19.6%),slowly increasing group(47.8%),and decreasing group(32.6%).Logistic regression analysis showed that age,sleep,social support,number of comorbidities,body mass index(BMI),pain and fear of exercise were the factors influencing the potential categories of fatigue trajectory in the DPN patients.Conclusions There are three potential categories of fatigue trajectories in DPN patients.Age,sleep disorders,social support,comorbidities,BMI,pain score,and exercise fear were influencing factors of fatigue in patients with DPN.

Background Mitochondrial dynamin-related protein 1 (DRP1) regulates mitochondrial division and plays an important role in maintaining hepatocyte function. However, the role of DRP1 in cadmium exposure-induced maternal liver damage in pregnant mice remains unclear. Objective To investigate the role and mechanism of DRP1 in maternal liver damage induced by cadmium exposure during pregnancy. Methods This study consisted of animal experiments and cell experiments. (1) Animal experiments. Mice at 14 days of gestation were randomly divided into three groups: a control group, a low-dose cadmium group (LCd group: 2.5 mg·kg⁻¹), and a high-dose cadmium group (HCd group: 5 mg·kg⁻¹). The pregnant mice were intraperitoneally injected with cadmium chloride (CdCl₂) for 6 and 24 h in the next morning. The weights of pregnant mice, uterus, maternal liver, and fetal mice were recorded after sacrifice. Serum and liver of pregnant mice were collected, the levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in serum were detected, and liver tissues were stained with HE to observe changes in liver function and liver tissue structure. The expressions of oxidative phosphorylation-related proteins, hypoxia inducible factor-1α (HIF-1α) and DRP1 proteins in liver of pregnant mice were detected by Western blotting. (2) Cell experiments. AML12 cells were treated with CdCl₂ (10 μmol·L⁻¹) for 0, 2, 6, 12, and 24 h. The expressions of oxidative phosphorylation-related proteins, DRP1, and hypoxia inducible factor-1α (HIF-1α) proteins were detected. AML12 cells were pretreated with DRP1 inhibitor Mdivi-1 for 1 h and then CdCl₂ (10 μmol·L⁻¹) for 12 h to detect the expression of oxidative phosphorylation-related proteins and DRP1 protein. AML12 cells were treated with Hif-1α siRNA for 48 h and CdCl₂ (10 μmol·L⁻¹) for 6 h to detect the expression of HIF-1α and DRP1 proteins. Results The results of animal experiments showed that cadmium exposure in pregnant mice had no effects on maternal liver weight and liver coefficient. However, the histomorphological changes and necrosis in hepatocytes were observed. Compared with the control group, the serum ALT and AST levels of pregnant mice in the LCd group were significantly increased after 6 h (P＜0.05), and the levels in the HCd group were significantly increased after 6 and 24 h (P＜0.05). Cadmium exposure during pregnancy significantly up-regulated HIF-1α and DRP1 expressions and down-regulated the expressions of oxidative phosphorylation-related proteins in maternal livers. In vitro cell experiments showed that the expressions of oxidative phosphorylation-related proteins was significantly decreased and HIF-1α and DRP1 protein expressions were significantly increased in the AML12 cells treated with CdCl₂ for 6 h. Mdivi-1 pretreatment significantly antagonized the inhibitory effect of cadmium on the expressions of oxidative phosphorylation-related proteins in AML12 cells, while Hif-1α siRNA pretreatment significantly antagonized the up-regulative effect of cadmium on DRP1 expression in AML12 cells. Conclusion Cadmium exposure in pregnant mice may up-regulate DRP1 expression by activating HIF-1α signaling, then inhibit oxidative phosphorylation level of hepatic cells, and ultimately lead to maternal liver damage.

Objective:To investigate the intention to participate in health care in transitional children and adolescents with diabetes and analyze its influencing factors.Methods:This was a cross-sectional survey study. From March to October 2021, 185 children and adolescents with diabetes were selected as research subjects by convenience sampling method from People′s Hospital Affiliated to Jiangsu University. General data questionnaire, Participation in Health Care Intention Questionnaire, Health Literacy Scale and Diabetes Self-management Scale were used to investigate, and multiple linear regression was used to analyze the influencing factors of the population′s intention to participate in health care.Results:The transitional children and adolescents with diabetes participation in health care intention total score was (124.87 ± 16.31) points, the health literacy total score was (33.70 ± 4.38) points, diabetes self-management total score was (35.11 ± 5.19) points. The regression analysis found that age, course of the disease, diabetes type, family structure modes, health literacy, and self-management ability were the main factors influencing adolescents involved in health care intention ( t values were -1.99-2.66, all P<0.05), including health literacy ability and disease management ability was positively correlated with the disease ( r = 0.250, 0.232, both P<0.01). Conclusions:The transitional children and adolenscents with diabetes have a medium level of intention to participate in health care. The transitional children and adolenscents with older age, longer disease course and nuclear family structure had higher levels of health care intention. The higher the level of health literacy and self-management, the higher the level of intention to participate in health care, medical staff should take targeted measures to improve the intention to participate in health care, promote this group to improve disease management ability and quality of life.

Objective:To compare the long-term clinical efficacy of simultaneous pancreas-kidney transplantation (SPK) in the treatment of type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM) with end-stage renal disease (ESRD) , and to explore whether T2DM with ESRD can be an indication for SPK.Methods:A total of 62 cases of SPK performed in our center were retrospectively analyzed. Based on the same baseline principle, the patients were divided into T1DM group (30 cases) and T2DM (32 cases) according to the primary disease of diabetes.Results:There was no significant difference in male gender, preoperative hemoglobin or HbA1c between the two groups. Compared with T2DM group, both of the age at surgery [ (31.8±5.2) years vs (49.5±5.7) years, P<0.001] and body mass index [ (21.8±1.3) kg/m 2 vs (25.0±3.8) kg/m 2, P<0.001] were lower in T1DM group. Compared with T2DM, the insulin dosage in the T1DM was higher, and there was no C-peptide release, and the difference was statistically significant. The patients were followed up for 5 years. There were no significant differences in fasting blood glucose, HbA1c, C-peptide, serum creatinine or eGFR between the two groups at 1, 3 and 5 years after surgery. The incidence of pulmonary infection, BK virus infection and acute rejection of transplanted kidney in T1DM group was lower than that in T2DM group, but the difference was not statistically significant. At 1 and 3 years after transplantation, the survival rates of recipients, transplanted pancreas and kidneys were 100% in both groups. In the 5th year, one patient in T2DM group died of acute myocardial infarction at 48 months after surgery, but the renal and pancreatic grafts functioned well. The survival rate of recipients in T1DM group (100%) was higher than that in T2DM group (96.9%) on 5 years after surgery ( P=0.333) , but the difference was not statistically significant. After excluding the deceased recipients, the transplanted pancreas and kidneys in both groups survived. Conclusions:There is no significant difference in the short and long-term clinical outcomes between patients with T2DM and ESRD who received SPK and those with T1DM and ESRD. T2DM with ESRD can be an indication for SPK, but a large sample size study is still needed to further improve the selection criteria.

【Objective】 To investigate the effect of transfusion-transmitted Zika virus (ZIKV) on the expression of non-coding circular RNA (hsa_circ_0001613) and the role of hsa_circ_0001613 in Zika virus replication. 【Methods】 Human adenocarcinomic alveolar basal epithelial cells (A549) were seeded on a 12-well plate at 1.8×10⁵/ well and infected with ZIKV at 0.05 MOI. The Total RNAs were isolated every day for 5 days after infection, and the relative expression level of hsa_circ_0001613 was detected by qRT-PCR. In addition, 10nM siRNA-hsa_circ_0001613 was transfected into 2×10⁵/ well A549 cells to specifically knock down the expression level of hsa_circ_0001613. 24h later, the cells were infected with ZIKV (MOI=0.05). Total RNAs were isolated at day 1-5 post-infection, proteins were extracted 96h post-infection. ZIKV replication, relative host antiviral gene expression, and interferon stimulated response element (ISRE) activity were tested using qRT-PCR, western blot and dual luciferase assay, respectively. 【Results】 The relative expression of hsa_circ_0001613 decreased significantly after 1-5 days of ZIKV infection. Knockdown of hsa_circ_0001613 inhibited ZIKV replication. Meanwhile, hsa_circ_0001613 knockdown significantly upregulated IFN-α/β and its downstream interferon-stimulated genes (ISGs) expression, also increased ISRE activity. 【Conclusion】 ZIKV infection significantly suppressed hsa_circ_0001613 expression in A4549 cells. Preliminary study indicated that hsa_circ_0001613 knockdown inhibited ZIKV replication possibly through activating type-Ⅰ IFN signaling pathway as showed by increased ISGs expression and ISRE activity.
