Objective To evaluate the regulatory effect of Diwu Yanggan(DWYG)Decoction on lysoglycerophospholipids(Lyso-GPLs)in circulating exosomes in a mouse model of nonalcoholic fatty liver disease(NAFLD).Methods Circulating exosomes isolated from mouse serum by size exclusion chromatography were morphologically characterized using transmission electron microscope and examined for surface markers CD9,CD63 and TSG101 using Western blotting.Twenty-four male Kunming mice were randomized into 3 groups for normal feeding(control,n=8)or high-fat diet feeding for 1 week to induce NAFLD,after which the latter mice were given DWYG decoction(treatment group,n=8)or normal saline(model group,n=8)by gavage for 4 weeks.After the last treatment,blood samples were collected from the mice for testing serum TC,HDL-C,LDL-C,ALT and AST levels and isolating circulating exosomes.Using multivariate statistical analysis based on targeted metabolomics strategy,the potential biomarkers for Lyso-GPLs in the exosomes were screened.Results The isolated exosomes about 100 nm in size had a typical saucer-like structure with distinct double-layer membranes and a mean particle size of 137.5 nm and expressed the specific surface marker proteins CD9,CD63 and TSG101.The mouse models of NAFLD had significantly increased serum levels of TC,HDL-C,LDL-C and AST and lowered serum ALT level.A total of 43 Lyso-GPLs with significant reduction after DWYG Decoction treatment were identified in NAFLD mice.Conclusion DWYG Decoction can regulate Lyso-GPLs in circulating exosomes in NAFLD mice,which provides a new clue for studying the therapeutic mechanism of DWYG Decoction for liver disease.

Objective To explore the effect of task-oriented training of intelligent mirror gloves combined with low-frequency repeti-tive transcranial magnetic stimulation(rTMS)on hand function recovery in stroke patients. Methods From October 1st,2022 to June 30th,2023,136 stroke patients in Northern Jiangsu People's Hospital were ran-domly divided into control group,mirror group,rTMS group and combination group,with 34 patients in each group.All the groups received routine rehabilitation treatment.In addition,the mirror group received task-orient-ed training of intelligent mirror gloves,rTMS group received low-frequency rTMS,and the combination group received task-oriented training combined with low-frequency rTMS,for four weeks.The Fugl-Meyer Assess-ment-Upper Extremities(FMA-UE)score,Wolf Motor Function Test(WMFT)score,and surface electromyo-graphic root mean square(RMS)of forearm extensor and flexor muscle groups on the affected/healthy side be-fore and after treatment were compared.And the differences of transcranial magnetic stimulation-motor-evoked potentials(MEP)between rTMS group and combination group before and after treatment were also compared. Results Four cases in the control group,seven in the mirror group,five in rTMS group and six in the combination group dropped off.The intra-group effect(F>996.656,P<0.001),inter-group effect(F>20.333,P<0.001)and inter-action effect(F>72.796,P<0.001)were significant in the scores of FMA-UE and WMFT,and the RMS ratio of forearm extensor and flexor muscle groups among four groups,in which the combination group was the best.After treatment,the amplitude of MEP increased in rTMS group and combination group(|t|>3.842,P<0.05),and was higher in the combination group than in rTMS group(t=-3.060,P<0.01). Conclusion The task-oriented training of intelligent mirror gloves combined with low-frequency rTMS could effectively promote the recovery of hand function in stroke patients.
