As a physical treatment technique, modified electro-convulsive therapy (MECT) is used to treat mental and certain neurological disorders by causing seizures with short, suitable electrical currents applied to the brain while the patient is under general anesthesia and muscle relaxants. MECT is recognized for its therapeutic efficacy and clinical safety, rendering it one of the most prevalent interventions in psychiatric care. To enhance clinical outcomes and minimize adverse effects, this consensus document delineates the indications, therapeutic parameters, therapeutic procedures, potential adverse effects, and associated management strategies for MECT. These guidelines are informed by the latest clinical research and expert consensus, integrating evidence-based medicine methodologies. The objective is to furnish clinicians with precise operational guidelines and to advance the standardization of MECT practices in clinical settings.

Objective To observe the value of three-dimensional ultrasound combined with microvascular flow imaging for prenatal diagnosis of fetal intracranial anomalies.Methods Totally 118 fetuses with intracranial anomalies diagnosed through cranial MRI/induced labor specimen dissection who underwent prenatal ultrasound examination were retrospectively enrolled.Two-dimensional,three-dimensional ultrasound and microvascular flow imaging manifestations of fetal intracranial anomalies were observed,and the accuracy of three-dimensional ultrasound combined with microvascular flow imaging for prenatal diagnosis of fetal intracranial anomalies was analyzed.Results The accuracy of three-dimensional ultrasound combined with microvascular flow imaging for prenatal diagnosis of fetal intracranial anomalies was 93.22％(110/118),of isolated and non-isolated intracranial anomalies was 97.47％(77/79)and 84.62％(33/39),respectively.Six fetuses were missed diagnosis of malformations of cortical development(1 fetus of tuberous sclerosis,4 of abnormal morphology of the sulci gyrus and 1 of schizencephaly)and 1 fetus of intracranial softening lesion,while posterior fossa arachnoid cyst in 1 fetus was misdiagnosed as mega cisterna magna.Conclusion The accuracy of three-dimensional ultrasound combined with microvascular flow imaging for prenatal diagnosis of fetal intracranial anomalies was relatively high.

Objective To observe prenatal ultrasonic findings of fetal malformation of cortical development(MCD).Methods Totally 37 singleton fetuses with MCD diagnosed by fetal cranial MRI and/or genetic examination were retrospectively enrolled,and prenatal ultrasonic manifestations were observed.Results Among 37 fetuses,29(29/37,78.38％)were found with abnormal Sylvian fissure,26(26/37,70.27％)with widened/asymmetrical lateral ventricles,22(22/37,59.46％)with abnormal surface sulci,14(14/37,37.84％)with abnormal cavity of septum pellucidum(CSP)/corpus callosum(CC),11(11/37,29.73％)with midline deviation/curvature,11(11/37,29.73％)with widened subarachnoid space,10(10/37,27.03％)with head circumference＜2 standard deviation below mean value,9(9/37,24.32％)with abnormalities in the cerebellar hemisphere/vermis,7(7/37,18.92％)with abnormal echoes in the brain parenchyma,7(7/37,18.92％)with midline cysts and 2(2/37,5.41％)with enlarged ganglion eminence.Conclusion Fetal MCD mainly presented as abnormal Sylvian fissure,widened/asymmetrical lateral ventricles and abnormal surface sulci,which might accompanied by abnormal CSP/CC,midline deviation/curvature,widened subarachnoid space and abnormal head circumference in prenatal ultrasound.

Objective:To explore the risk factors for malnutrition after a traumatic brain injury and to construct a model which usefully predicts that risk.Methods:This was a retrospective study of 374 patients with a craniocerebral injury for whom the relevant clinical data were available. Based on their nutritional status, they were stratified into a malnutrition group ( n=220) and a control group ( n=154). Univariate and multivariate logistic regressions were evaluated seeking to identify the independent risk factors associated with malnutrition, and a prediction model was constructed based on the results. The model′s discrimination ability and accuracy were assessed using a receiver operating characteristics (ROC) curve. Results:A total of 220 patients (58.8%) developed malnutrition. Multifactorial logistic regression analysis showed that the independent risk factors for malnutrition were: age ≥60 years, pulmonary infection, dysphagia, cognitive impairment, a GCS score ≤8, or a Barthel index ≤40. In the ROC curve analysis, the area under the curve quantifying the model′s ability to predict malnutrition was 0.924 (95% CI: 0.896, 0.951), with a sensitivity of 0.868 and a specificity of 0.857, indicating its good prediction performance. Conclusions:Age ≥60 years, pulmonary infection, dysphagia, cognitive impairment, a GCS score ≤8 or a Barthel index ≤40 are independent predictors of malnutrition after a traumatic brain injury. The prediction model constructed based on those risk factors has demonstrated useful predictive power for malnutrition.

A colon-specific drug delivery system has great potential for the oral administration of colorectal cancer. However, the uncontrollable in vivo fate of liposomes makes their effectiveness for colonic location, and intratumoral accumulation remains unsatisfactory. Here, an oral colon-specific drug delivery system (CBS-CS@Lipo/Oxp/MTZ) was constructed by covalently conjugating Clostridium butyricum spores (CBS) with drugs loaded chitosan (CS)-coated liposomes, where the model chemotherapy drug oxaliplatin (Oxp) and anti-anaerobic bacteria agent metronidazole (MTZ) were loaded. Following oral administration, CBS germinated into Clostridium butyricum (CB) and colonized in the colon. Combined with colonic specifically β-glucosidase responsive degrading of CS, dual colon-specific release of liposomes was achieved. And the accumulation of liposomes at the CRC site furtherly increased by 2.68-fold. Simultaneously, the released liposomes penetrated deep tumor tissue via the permeation enhancement effect of CS to kill localized intratumoral bacteria. Collaborating with blocking the translocation of intestinal pathogenic bacteria from lumen to tumor with the gut microbiota modulation of CB, the intratumoral pathogenic bacteria were eliminated fundamentally, blocking their recruitment to immunosuppressive cells. Furtherly, synchronized with lipopolysaccharide (LPS) released from MTZ-induced dead Fusobacterium nucleatum and the tumor-associated antigens produced by Oxp-caused immunogenic dead cells, they jointly enhanced tumor infiltration of CD8⁺ T cells and reactivated robust antitumor immunity.

BACKGROUND:Tyrosine kinase inhibitors,as well as other types of small-molecule cancer drugs,can cause severe cardiotoxicity. OBJECTIVE:To perform a heart safety re-evaluation by observing the effects of antitumor drugs on isolated heart electrocardiograph,cardiac action potential and associated ion channels and cytotoxicity. METHODS:Extracorporeal cardiac perfusion was given to the isolated rabbit heart using Langendorff perfusion:Sunitinib(0.3,3,10 μmol/L),Crizotinib(0.3,1,3 μmol/L),and Doxorubicin(1,30 μmol/L)were perfused sequentially for 120 minutes to record electrocardiograph and left ventricular pressure.A blank control group was set for comparison.Manual patch clamp was used to record the effects of Crizotinib,Sunitinib,Doxorubicin on hERG,Cav1.2,Nav1.5 channel currents and action potential in human induced pluripotent stem cell derived cardiomyocytes.Adenosine triphosphate level in human induced pluripotent stem cell derived cardiomyocytes was detected by CellTiter-Glo luminescent cell viability assay. RESULTS AND CONCLUSION:Isolated rabbit heart using Langendorff perfusion:Compared with the blank ontrol group,Sunitinib and Crizotinib at≥3 μmol/L decreased heart rate(P<0.01)and prolonged QT/QTc interval(P<0.01),and reduced left ventricular pressure to different extents.Manual patch clamp recording:Compared with the blank control group,Sunitinib and Crizotinib at 3 μmol/L inhibited the activities of hERG,Nav1.5 and Cav1.2 channels and significantly prolonged the duration of action potential(P<0.01).According to the analysis of the test article,the difference between the labeled concentration and the measured concentration of the recovered solution was not significant.Cell viability assays:Compared with the blank control group,adenosine triphosphate content in human induced pluripotent stem cell derived cardiomyocytes significantly decreased after treatment with Sunitinib(IC50=4.64 μmol/L),Doxorubicin(IC50=4.21 μmol/L)and Crizotinib(IC50=2.87 μmol/L),indicating that cell viability significantly decreased(P<0.01).To conclude,this study successfully established an early cardiac safety evaluation method for antitumor drugs,which provides good support and help for the subsequent development of antitumor drugs.
