Objective To investigate the effect of acacetin on oxidative stress injury in diabetic cataract(DC)rats and its regulation of sirtuin 1(Sirt1)/adenosine monophosphate-activated protein kinase(AMPK)/nuclear factor-erythroid 2-related factor 2(Nrf2)signaling pathway.Methods Sixty SD rats were randomly divided into the control group,model group,low-dose acacetin group,high-dose acacetin group,and acacetin+Sirt1 inhibitor(EX527)group.DC rat models were constructed except for the control group.Rats in the low-dose and high-dose acacetin groups were injected with 10 mg·kg-1 and 20 mg·kg-1 acacetin subcutaneously through the neck,twice a day,respectively.Rats in the acacetin+EX527 group were injected with 20 mg·kg-1 acacetin subcutaneously through the neck,twice a day;additionally,3.5 mg·kg-1 EX527 was administered subcutaneously through the osmotic micro-pump for 4 weeks.The same amount of nor-mal saline was pumped into rats in the rest groups for 4 weeks.After administration,blood pressure and fasting blood glu-cose(FBG)were measured.The lens opacity was observed under the slit lamp irradiation,and the histopathological chan-ges in the lens were observed after hematoxylin-eosin staining.Enzyme-linked immunosorbent assay was performed to de-termine the serum levels of malondialdehyde(MDA),superoxide dismutase(SOD),glutathione peroxidase(GSH-Px),in-terleukin(IL)-6,and IL-1 β.Western blot was applied to detect the expression levels of Sirt1,phosphorylated AMPK(p-AMPK),AMPK,and Nrf2 proteins.Results Compared with the control group,the lens epithelial cells(LECs)of rats in the model group showed patchy and striped shapes,and migration and aggregation occurred;the systolic blood pres-sure(SBP),FBG,lens opacity score,and the levels of MDA,IL-6 and IL-1 β increased,while the expression levels of SOD,GSH-Px,Sirt1,p-AMPK/AMPK,and Nrf2 proteins decreased(all P＜0.05).Compared with the model group,the migration and aggregation of LECs improved in the low-dose and high-dose acacetin groups,the SBP,FBG,lens opacity score,and the levels of MDA,IL-6 and IL-1 β decreased,while the expression levels of SOD,GSH-Px,Sirt1,p-AMPK/AMPK,and Nrf2 proteins increased(all P＜0.05).Compared with the high-dose acacetin group,the morphological chan-ges and aggregation of LECs in the acacetin+EX527 group were more significant,the SBP,FBG,lens opacity score,and the levels of MDA,IL-6 and IL-1 β increased,while the expression levels of SOD,GSH-Px,Sirt1,p-AMPK/AMPK,and Nrf2 proteins decreased(all P＜0.05).Conclusion Acacetin may protect DC rats from oxidative stress injury by activating the Sirt1/AMPK/Nrf2 pathway.

Objective To investigate the effect of total flavone of Cydonia oblonga on oxidative damage of human lens epithelial cells induced by high glucose and its mechanism.Methods A cell injury model was established by inducing human lens epithelial cells with high glucose.Human lens epithelial cells were cultured in the medium containing 30 mmol·L-1 glucose for 24 h,which was recorded as the high glucose group.Cells in the control group were cultured in a medium con-tainning 5.5 mmol·L-1 glucose for 24 h.Human lens epithelial cells were inoculated into 96-well plates with 5 × 103 cells per well,and treated with mediums containing 10 mmol·L-1,20 mmol·L-1,and 40 mmol·L-1 total flavone of Cydonia ob-longa combined with 30 mmol·L-1 glucose for 24 h.They were recorded as high glucose+low total flavone of Cydonia oblonga group,high glucose+medium total flavone of Cydonia oblonga group,and high glucose+high total flavone of Cydonia oblonga group.Human lens epithelial cells were transfected with anti-miR-NC and anti-miR-370 with Lipo-fectamine2000 transfection reagent,and treated with 30 mmol·L-1 glucose for 24 h,which were recorded as high glucose+anti-miR-NC group and high glucose+anti-miR-370 group.Human lens epithelial cells were transfected with miR-NC and miR-370 mimics,and treated with medium containing 30 mmol·L-1 glucose and 40 mmol·L-1 total flavone of Cydonia oblonga for 24 h,which were labeled as high glucose+total flavone of Cydonia oblonga+miR-NC group and high glucose+total flavone of Cydonia oblonga+miR-370 group.The activities of superoxide dismutase(SOD)and cata-lase(CAT),and the content of malondialdehyde(MDA)were measured by Enzyme-linked immunosorbent assay;flow cy-tometry was applied to detect apoptosis rate;quantitative reverse transcription polymerase chain reaction was applied to detect the expression level of miR-370;Western blot was applied to detect the expression of apoptosis-related proteins.Results Compared with the control group,the activities of SOD and CAT decreased and the content of MDA increased in the human lens epithelial cells of the high glucose group,and the differences were statistically significant(all P＜0.05);compared with the high glucose group,the activities of SOD and CAT significantly increased and the content of MDA signifi-cantly decreased in the high glucose+low total flavone of Cydonia oblonga group,the high glucose+medium total fla-vone of Cydonia oblonga group and the high glucose+high total flavone of Cydonia oblonga group(all P＜0.05).Com-pared with the control group,apoptosis rate,and protein expressions of Caspase-3 and Caspase-9 of human lens epithelial cells in the high glucose group significantly increased(all P＜0.05);compared with the high glucose group,the apoptosis rate,Caspase-3 and Caspase-9 protein expressions of human lens epithelial cells in the high glucose+low total flavone of Cydonia oblonga group,high glucose+medium total flavone of Cydonia oblonga group,and high glucose+high total fla-vone of Cydonia oblonga group significantly decreased(all P＜0.05).The expression levels of miR-370 in human lens epi-thelial cells were 1.00±0.00,4.04±0.36,3.22±0.24,2.42±0.23 and 1.62±0.14 in the control group,high glucose group,high glucose+low total flavone of Cydonia oblonga group,high glucose+medium total flavone of Cydonia oblon-ga group,and high glucose+high total flavone of Cydonia oblonga group,respectively.There was a statistically different significance among the five groups(F=256.138,P＜0.05).Compared with the high glucose+anti-miR-NC group,the ex-pression of miR-370 significantly decreased,the activities of SOD and CAT significantly increased,and the content of MDA significantly decreased in human lens epithelial cells of the high glucose+anti-miR-370 group(all P＜0.001).Compared with the high glucose+anti-miR-NC group,apoptosis rate,and protein expressions of Caspase-3 and Caspase-9 of the hu-man lens epithelial cells in the high glucose+anti-miR-370 group significantly decreased(all P＜0.001).Compared with the high glucose+total flavone of Cydonia oblonga+miR-NC group,the activities of SOD and CAT significantly de-creased,and the content of MDA,apoptosis rate,and protein expressions of Caspase-3 and Caspase-9 significantly in-creased in the human lens epithelial cells of high glucose+total flavone of Cydonia oblonga+miR-370 group(all P＜0.001).Conclusion The expression of miR-370 increases in high glucose-induced human lens epithelial cells.Total fla-vone of Cydonia oblonga can inhibit the oxidative stress and apoptosis of high glucose-induced human lens epithelial cells,and the mechanism may be related to the decreased expression of miR-370.

OBJECTIVES: To develop a Chinese version of the Stress Adaption Scale (SAS) and to assess its reliability and validity among Chinese patients with multimorbidity. METHODS: The Brislin model was used to translate, synthesize, back-translate, and cross culturally adapt the SAS. A total of 323 multimorbidity patients selected by convenience sampling method from four hospitals in Zhejiang province. The critical ratio method, total question correlation method, and graded response model (item characteristic curve and item discrimination) were used for item analysis. Cronbach's alpha coefficient and split-half reliability were used for the reliability analysis. Content validity analysis, structural validity analysis, and criterion association validity analysis were performed by expert scoring method, confirmatory factor analysis, and Pearson correlation coefficient method, respectively. RESULTS: The Chinese version of the SAS contained 2 dimensions of resilience and thriving, with a total of 10 items. In the item analysis, the critical ratio method showed that the critical ratio of all items was greater than 3.0 (P<0.001); the correlation coefficient method showed that the Pearson correlation coefficients for all items exceeded 0.4 (P<0.01). The graded response model showed that items of the revised scale exhibited distinct item characteristic curves and all items had discrimination parameters exceeding 1.0. In the reliability analysis, Cronbach's alpha coefficient of the revised Chinese version of the SAS scale was 0.849, and the split-half reliability was 0.873. In the validity analysis, the item-level content validity index and scale-level content validity index both exceeded 0.80. In the confirmatory factor analysis, the revised two-factor model showed satisfactory fit indices (χ²/df=3.115, RMSEA=0.081, RMR=0.046, GFI=0.937, AGFI=0.898, CFI=0.936, TLI=0.915). In the criterion-related validity analysis, the Chinese version of the SAS score was negatively correlated with the Perceived Stress Scale and the Treatment Burden Questionnaire, with correlation coefficients of －0.592 and －0.482, respectively (both P<0.01). CONCLUSIONS The Chinese version of the SAS has good reliability and validity, which can be used to evaluate the stress adaption capacity among multimorbidity patients in China, and provides a reference for developing individualized health management measures.

Objective:To explore the effects of mechanical factors on the morphology of the growth plate and proximal femur development, in order to provide a mechanical basis for the mechanism of Cam lesions in femoral acetabular impingement (FAI).Methods:Using CT scan data of hip joint from adolescents, we constructed three-dimensional finite element models of normal and extended proximal femoral epiphyseal growth plates. Dynamic mechanics and position data from daily activities (walk, stand on one and two feet, go upstairs and downstairs, sit and stand up, squat and stand up) and basketball layup drills were collected from five healthy volunteers using the Vicon system. The mean values of femoral head mechanical loads and positions at peak values, movement onset, and termination were selected for finite element analysis to observe the distribution of equivalent stress, normal stress, and shear stress on the two growth plate models under different activity modes.Results:Successful construction of three-dimensional finite element models for normal and extended proximal femoral epiphyseal growth plates was achieved. Mechanical load values and spatial positions of the femoral head during daily activities and layup movements were obtained. In daily activities, peak equivalent stress values for normal and extended growth plates ranged from 1.6 to 11.0 MPa; compressive stress ranged from 1.7 to 12.0 MPa; tensile stress ranged from 0.5 to 10.0 MPa; and shear force ranged from 0.4 to 7.1 MPa. The compressive stress during walking, standing on one or both feet, going up and down stairs, sitting and standing, and squatting was concentrated in the central and lateral areas; tensile stress was concentrated in the central and medial areas; shear force was concentrated in the medial area and the anterior and posterior edges of the growth plate. During a layup, the compressive stress in the center, outer upper side, and medial edge of the growth plate of the normal model was notably concentrated, with peaks fluctuating between 5.5-19.0 MPa, 5.7-11.0 MPa, and 5.4-7.3 MPa respectively; tensile stress and shear force were concentrated at the inner and outer edges as well as in the central area, with peaks fluctuating between 3.0-24.0 MPa and 3.0-26.0 MPa respectively, these values were significantly different from those observed during daily activities. For the elongated growth plate, compressive stress was concentrated at the central and lateral edges with peaks fluctuating between 17.0-41.0 MPa and 17.0-38.0 MPa respectively; simulated shear stress and tensile stress showed significant concentration at peaks fluctuating between 4.9-34.0 MPa, also significantly different from those observed during daily activities.Conclusion:The difference in mechanical distribution between daily activities, basketball layup training, as well as between normal and extended growth plates may be the mechanical initiating factor in the development of extended growth plates and the formation of Cam lesions, it may be the mechanical initiating factor for the development of extended growth plates and the collision of Cam lesions in FAI.

To explore the potential associations between perceived stress and health-promoting behaviors based on the theoretical schema of the middle-range theory of adaptation to chronic illness. From January to May 2021, a convenience sampling method was used to recruit 230 young and middle-aged patients with metabolic syndrome who underwent physical examination in the inpatient center of Sir Run Run Shaw Hospital, Zhejiang University School of Medicine. The Health-Promoting Health Profile-Ⅱ, Chinese Perceived Stress Scale, Coping and Adaptation Processing Scale-Short Form, and Multi-dimensional Scale of Perceived Social Support were used in the cross-sectional study. The chain mediation effect procedure and bootstrap sampling test were used to examine the mediating role of adaptability and social support between perceived stress and health-promoting behaviors. The mean score of health-promoting behaviors was 100.0±14.6, the mean score of perceived stress was 22.0± 6.9, the mean score of adaptability was 47.0±6.1, and the mean score of social support was 63.8±10.8. Perceived stress had a negative impact on patients' health-promoting behaviors (=-0.309, <0.05). The adaptability (effect size= -0.112, 95%:-0.199~-0.038) and social support (effect size= -0.032, 95%:-0.083~played a mediating role and a chain mediating role in the process of perceived stress influencing patients' health-promoting behaviors (effect size= -0.045, 95%:-0.093~-0.020). Adaptability and social support play an intermediary role between perceived stress and health-promoting behaviors in young and middle-aged patients with metabolic syndrome. Healthcare professionals can motivate patients to develop healthy behaviors by developing intervention strategies on adaptability and social support.

OBJECTIVE: To screen the differentially expressed proteins at the early stage of K562 cells treated with meisoindigo by using tandem mass tags (TMT)-based proteomics technology, and to explore the mechanism for meisoindigo-inducing apoptosis. METHODS: The half inhibitory concentration (IC) of mesoindigo on K562 cells was determined by CCK8. The flow cytometry was used to assay the apoptosis of K562 cells treated by meisoindigo or DMSO. Total proteins were extracted from the cells treated with 0.2% DMSO (control) or 20 μmol/L meisoindigo (Test) for 2 hours. Then, the TMT-labeling HPLC-MS/MS was used to identify and quantify the peptides and their abundance, all the tests were repeated for 3 times. The Mascot software was used to identify the proteins; the GO annotations, enrichment and cluster analysis were used to analyze the differentially expressed proteins. RESULTS: Meisoindigo-induced K562 cell apoptosis in a dose-dependent manner (r=0.98), 5 544 proteins were identified, 4792 of which were quantified. The protein with expression difference>1.5-folds in Test group accoanted for 8, out of which the expression of 4 proteins were up-regulated and 4 were down-regulated. The differentially expressed proteins mainly associated with reactive oxygen species (ROS). CONCLUSION Several proteins including DDIT4 were found to have dramatic changes in the early stage of K562 cells treated with meisoindigo by using quantitative proteomics technology. The ROS metabolic process may play important roles in meisoindigo-inducing apoptosis of K562 cells.
