BackgroundCombination of antipsychotic drugs and modified electroconvulsive therapy （MECT） is currently a commonly used method for treating schizophrenia， but its efficacy varies among different patient groups. ObjectiveTo explore the therapeutic effects of MECT on schizophrenia patients living in different urban versus rural environments， so as to provide references for the selection of treatment plans based on patients' residence. MethodsA total of 587 patients hospitalized at Luzhou Mental Health Center， Zigong Mental Health Center and Yibin Fourth People's Hospital from May 2018 to August 2022， who met the diagnostic criteria for schizophrenia in the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5） ，were included in the study. Patients were divided into two groups： medication-only group （n=106） and MECT combined with medication group （n=481）. In MECT combined with medication group， 24 rural patients residing in urban areas were excluded， leaving the remaining patients divided into urban group （n=103） and rural group （n=354） based on their place of residence. Positive and Negative Syndrome Scale （PANSS） was used to assess the severity of symptoms. Clinical efficacy was evaluated using PANSS score reduction rate， and covariance analysis was used to compare the therapeutic effects of different patients. ResultsThe differences of reduction rate of PANSS total score， positive symptom scale score and negative symptom scale score as well as treatment effectiveness rate between MECT combined with medication group and medication-only group were statistically significant （F=11.149， 12.111， 31.725， χ²=14.010， P<0.01）. Statistically significant differences were also observed in reduction rate of PANSS total score and positive symptom subscale score as well as treatment effectiveness rate between urban and rural patients in MECT combined with medication group （F=3.946， 4.523， χ²=4.033， P<0.05）. ConclusionThe efficacy of MECT combined with medication may be superior to medication alone in the treatment of schizophrenia， and the combined therapy may be more effective in urban patients than that in rural patients， with potentially more pronounced improvements in positive symptoms.

Objective:To apply cardiovascular magnetic resonance (CMR) to quantitatively evaluate the morphology and tissue characteristics of thoracic skeletal muscle (TSM) in patients with Danon disease and hypertrophic cardiomyopathy (HCM), in order to provide auxiliary differential diagnostic information.Methods:A retrospective study was conducted on 15 Danon disease patients (Danon disease group) who completed CMR examination, and 15 HCM patients (HCM group) and 15 healthy volunteers (control group) who were matched by gender and age were compared. TSM (pectoralis major, pectoralis minor, erector spinae, and subscapularis) area index (TSMAi), T1 relaxation time of four groups, and extracellular volume (ECV) of skeletal muscles of two groups (pectoralis major and subscapularis) were measured for all subjects. Single factor analysis of variance and KruskalWallis test were used to compare three sets of values.Results:The total TSMAi of the Danon disease group was lower than that of the HCM group and the control group [(15.37±3.28)cm 2/m 2 vs (23.02±3.88)cm 2/m 2 vs (22.33±4.67)cm 2/m 2, P<0.001], and the TSMAi of each TSM was also lower than that of the HCM group and the control group (all P<0.05). There was no statistically significant difference in TSMAi between the HCM group and the control group (all P>0.05). The native T1 values of the pectoralis major muscle in the Danon disease group and HCM group were higher than those in the control group (all P<0.05). The ECV of the pectoralis major muscle and subscapularis muscle in the Danon disease group were higher than those in the HCM group and control group, and the enhanced T1 values were lower than those in the HCM group and control group (all P<0.05); There was no statistically significant difference in ECV and the enhanced T1 values between the HCM group and the control group ( P>0.05). Conclusions:The application of CMR can effectively evaluate the changes in TSM morphology and tissue characteristics in Danon disease patients. Compared with HCM patients, Danon disease patients showed significant atrophy of TSM with increased extracellular volume. CMR provides a quantitative reference for TSM in the differential diagnosis of the two.

ObjectiveTo investigate the mechanism of salvianolic acid F （Sal F） in repairing the high glucose-induced injury in human kidney-2 （HK-2） cells via the B-cell lymphoma-2 （Bcl-2）-associated X protein （Bax）/cysteinyl aspartate-specific proteinase 3 （Caspase-3）/gasdermin-E （GSDME） pathway. MethodThe cell counting kit-8 （CCK-8） was used to measure the relative viability of HK-2 cells exposed to high glucose and different concentrations （2.5， 5， 10， 20 μmol·L^-1） of Sal F and the relative viability of HK-2 cells treated with Sal F for different time periods. The levels of lactate dehydrogenase （LDH） and interleukin-1β （IL-1β） in the supernatant of the cell culture were measured by the LDH assay kit and enzyme-linked immunosorbent assay （ELISA） kit， respectively. Flow cytometry combined with Annexin V-FITC/propidium iodide （PI） and Hoechst 33342/PI staining was employed to reveal the proportion of PI-positive HK-2 cells exposed to high glucose. Western blotting was employed to determine the protein levels of Bax， Bcl-2， cytochrome C， cysteinyl aspartate-specific proteinase （Caspase）-9， Caspase-3， and GSDME in the HK-2 cells exposed to high glucose and treated with Sal F. The 2，7-dichlorodihydrofluorescein diacetate fluorescence probe （DCFH-DA） and mitochondrial membrane potential assay kit （JC-1） were used to determine the production of reactive oxygen species （ROS） and the mitochondrial membrane potential in the HK-2 cells exposed to high glucose and treated with Sal F. ResultCompared with the blank group， the model group showed decreased cell viability （P<0.01）， elevated levels LDH and IL-1β， increased proportion of PI-positive cells （P<0.01）， up-regulated protein levels of Bax， cytochrome C， Caspase-9， Caspase-3， and GSDME （P<0.01）， down-regulated protein level of Bcl-2 （P<0.01）， decreased mitochondrial membrane potential， and excessive ROS accumulation. Compared with the model group， Sal F repaired the high glucose-induced injury in HK-2 cells （P<0.05）， lowered the levels of LDH and IL-1β （P<0.05， P<0.01）， and decreased the proportion of PI-positive cells （P<0.01）. In addition， Sal F down-regulated the protein levels of Bax， cytochrome C， Caspase-9， Caspase-3， and GSDME and up-regulated the protein level of Bcl-2 （P<0.05， P<0.01）， increased the mitochondrial membrane potential， and decreased the accumulation of ROS in HK-2 cells. ConclusionSal F can reduce the production of ROS， restore the balance of mitochondrial membrane potential， and inhibit pyroptosis via the Bax/Caspase-3/GSDME signaling pathway to repair the high glucose-induced injury in HK-2 cells.

In recent years,public hesitancy to vaccinate has come to the fore and can hinder the advancement of immunization programs.It is important to increase public confidence in vaccines and to rationally and effectively promote the immunization behavior of the population.Based on behavioral economics theory,it combines the anchoring effect,loss aversion,two-systems theory,and the herd effect to explore the irrational factors and decision-making preferences behind the public's vaccination decisions,and then proposes discourse strategies for effective boosting to increase the public's confidence in vaccination.
