Objective: To explore the relationship between stigma and mental resilience in adolescent epilepsy patients and associated factors, so as to provide reference for future psychological intervention in adolescent patients with epilepsy. Methods: A total of 295 adolescent patients with epilepsy from Wuhan Mental Health Center were enrolled as participants from February 2021 to October 2024. The stigma was evaluated by Kilifi Stigma Scale for Epilepsy (KSSE), and psychological resilience was evaluated by Connor-Davidson Resilience Scale (CD-RISC). Associated factors of stigma and psychological resilience in adolescent patients with epilepsy were analyzed by multivariate Logistic regression analysis. Results: In the adolescent patients with epilepsy, KSSE score was (10.90±4.13) points, with 138 cases (46.78%) at low level, 154 cases (52.20%) at moderate level and 3 cases (1.02%) at high level. CD-RISC score was (50.19±5.97) points, there were 170 cases (57.63%) at low level and 125 cases (42.37%) at high level. Multivariate Logistic regression analysis showed that disease course >3 years ( OR =2.22), family history of epilepsy ( OR = 4.18) , monthly family income ≤5 000 yuan ( OR =2.05), single parent family ( OR =2.46) and middle and high stigma level ( OR = 1.72) had a higher risk on low level of mental resilience ( P <0.05). The course of disease >3 years ( OR =2.20), family history of epilepsy ( OR =3.54), general seizure ( OR =2.12), monthly family income ≤5 000 yuan ( OR =2.70), low level of mental resilience ( OR =2.03) of adolescent epilepsy patients showed a high risk on moderate high level of stigma ( P <0.05). Conclusions The stigma level is higher, while psychological resilience is lower in adolescent patients with epilepsy. Clinically, targeted intervention should be implemented based on related factors such as stigma in addescent patients with epilepsy.

Parkinson's disease is a neurodegenerative disease associated with abnormal copper metabolism in the brain,which leads to misfolding and aggregation of α-synuclein-copper complexes,which is an important pathological sign of Parkinson's disease.Copper metabolism,i.e.,cellular metabolic processes involving copper ions,is closely related to the pathogenesis of α-synuclein aggregation,dopamine metabolism,mitochondrial dysfunction,oxidative stress,and ferroptosis in Parkinson's disease.In this review,we summarize the molecular metabolic mechanism of copper toxicity by studying the pathological role of copper metabolism in Parkinson's disease,to support our further understanding of the mechanism of action and drug development.

Berberine is a natural isoquinoline alkaloid that was initially used as a broad-spectrum antibacterial agent in clinical treatment of enteritis,peptic ulcers,chronic gastritis,pneumonia,and other diseases.In recent years,in-depth study of the pharmacological effects of berberine has provided increasing evidence that berberine has neuroprotective effects on ischemic stroke.In this review,we introduce the effect of berberine on risk factors of ischemic stroke and discuss the neuroprotective effects of berberine on various mechanisms of ischemic stroke in detail to provide a reference for clinical and basic research in this field.

Objective:To explore the assessment value of quantitative parameters of dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI)and tumor markers in assessing the curative effect of neoadjuvant chemotherapy for breast cancer.Methods:A total of 75 patients with breast cancer who received neoadjuvant chemotherapy combined with surgical intervention in Jining No.1 People's Hospital from May 2019 to May 2022 were selected,and they were divided into effective group(54 cases)and ineffective group(21 cases)according to the Response Evaluation Criteria In Solid Tumour(RECIST).The Ve,Kep and Ktrans of DCE-MRI quantitative parameters and CEA,CA125 and CA15-3 levels of tumor markers between two groups were compared before and after chemotherapy,and the receiver operating characteristics(ROC)curve was adopted to analyze the predictive efficiency of each diagnostic method.Results:After chemotherapy,the differences of the Ve,Kep and Ktrans of quantitative parameters between the two groups were significant(t=7.237,51.695,16.879,P<0.05),respectively.The differences of the CEA,CA125 and CA15-3 of tumor markers between two groups were significant(t=44.201,6.736,6.885,P<0.05),respectively.The AUC value of combined prediction of 6 indicators included Ve,Kep,Ktrans,CEA,CA125 and CA15-3 was 0.979 in predicting the curative effect of neoadjuvant chemotherapy for breast cancer,which was significantly higher than the AUC value of each alone indicator,and the differences of them were statistically significant(Z=2.993,2.679,2.510,2.731,3.215,3.071,P<0.05),respectively.Conclusion:The combination of tumor markers and DCE-MRI quantitative parameters can better predict the curative effect of neoadjuvant chemotherapy for breast cancer,which can indirectly assess the prognosis.

Objective:To investigate the predictive value of infiltrating zone contrast-enhanced ultrasound(CEUS) gradient features in Nottingham grading and pathologically true infiltration of invasive ductal carcinoma(IDC).Methods:A retrospective analysis was performed on 78 female breast cancer patients (95 masses) confirmed by surgical and pathology in the Affiliated Hospital of Jiangsu University from July 2019 to June 2022, which were divided into Grade-Ⅰ (22 masses), Grade-Ⅱ (28 masses), and Grade-Ⅲ (45 masses) according to the Nottingham histological grading system. The differences in the maximum diameter of the infiltration zone and the characteristic parameters of the gradient of the inner and outer edges of the infiltration zone among the three groups of masses were compared, and the differential gradient features among them were analyzed by multivariate ordered Logistic regression and ROC curves. The relationship between the differential gradient characteristics of the infiltration zone and the pathologically true infiltration of the mass was further explored.Results:The univariate analysis showed statistically significant differences among the three groups for peak-arrival time gradient (ΔTTP), ascending branch slope gradient (ΔRS), peak intensity gradient (ΔPI) and area gradient under the curve (ΔAUC) (all P<0.05). Multiple ordered logistic regression analysis showed that ΔTTP, ΔPI and ΔAUC had independent influences on the histologic grading of IDC (all P<0.05), and the area under the curve for the combination of the three in predicting IDC histology grades Ⅰ, Ⅱ and Ⅲ was 0.692, 0.705 and 0.765, respectively. In addition, the maximum diameter of pathologically true infiltration of the mass was positively correlated with ΔTTP ( r=0.621, P<0.05) and negatively correlated with ΔPI ( r=-0.605, P<0.05) and ΔAUC ( r=-0.719, P<0.05). Conclusions:Infiltration zone CEUS gradient features are effective in predicting the histologic grade of IDC and strongly correlate with the degree of pathologically true infiltration of the mass.

AIM:To explore the protective effect of Xiaoxuming decoction(XXMD)on synaptic plasticity in the context of cerebral ischemia-reperfusion injury following ischemic stroke.METHODS:An oxygen-glucose depriva-tion/reoxygenation(OGD/R)model was employed in vitro using mouse hippocampal neurons(HT22 cells)to simulate ischemia-reperfusion injury.Cell viability was assessed using a CCK-8 assay to determine the optimal XXMD concentra-tion.The HT22 cells were divided into two groups:control and model(OGD/R).Cellular morphological changes were ob-served using an inverted microscope.The levels of IL-1β,IL-6 and TNF-α in the supernatant were quantified by ELISA.Ultrastructural changes were examined by transmission electron microscopy.Immunofluorescence staining was used to de-tect neuron markers NeuN and synaptic proteins NF200 and MAP2.The protein levels of NF200 and MAP2 were analyzed by Western blot.RESULTS:The highest cell survival rate occurred at an XXMD concentration of 100 mg/L(P<0.05).Compared with control group,the cells in model group exhibited round shape and shrinkage,mitochondrial swelling or vacuolization,and a marked decrease in survival rate.There were significant increases in IL-1β,IL-6 and TNF-α levels(P<0.05).Immunofluorescence intensity and protein levels of NeuN,NF200 and MAP2 were notably reduced(P<0.05).Treatment with XXMD improved cell morphology,ultrastructure and survival rate(P<0.05),and decreased in-flammatory factor levels(P<0.05).Compared with model group,the cells in OGD/R+XXMD group showed significantly increased immunofluorescence intensity and protein levels of NeuN,NF200 and MAP2(P<0.05).CONCLUSION:Xiaoxuming decoction may mitigate OGD/R-induced injury,potentially by inhibiting inflammatory responses and enhanc-ing synaptic plasticity.

BackgroundThe depressive episode is one of the most prevalent mental illnesses worldwide. Relaxation therapy as a psychotherapy for depressive disorder has shown itself to be a viable tool， yet the existing research on relaxation therapy combined with sertraline in the treatment of depressive episodes in children and adolescents is severely limited. ObjectiveTo discuss the effect of relaxation therapy combined with sertraline on the new-onset depressive episodes in children and adolescents， and to provide references for the treatment of depressive episodes in children and adolescents. MethodsFrom January 1， 2019 to December 31， 2020， a sample of 422 children and adolescents with depressive episodes attending the Child Mental Health Department of Sichuan Mental Health Center and fulfilling the International Classification of Diseases， tenth edition （ICD-10） diagnostic criteria were enrolled， and they were classified into study group （n=208） and control group （n=214） using random number table method. All participants were offered sertraline， based on this， study group was assigned to relaxation therapy for 25~30 min per day， five days per week for a period of two weeks. Hamilton Depression Scale 24-item （HAMD-24） and Hamilton Anxiety Scale （HAMA） were applied at the enrollment， the end of 2 weeks of treatment and the end of the 2^nd week after discharge. ResultsA total of 369 patients completed the study， including 185 in study group and 184 in control group. Analysis on HAMD-24 scores revealed a significant time effect， group effect and time×group interaction effect （F=813.279， 17.625， 8 994.905， P<0.01）. Significant time effect， group effect， and time×group interaction effect were noted on HAMA scores （F=635.041， 10.716， 13 945.986， P<0.01）. A reduction in HAMD-24 and HAMA scores was reported in study group at end of 2 weeks of treatment and end of the 2^nd week after discharge compared with baseline （t=0.924， 0.359， P<0.01）. At the end of the 2^nd week after discharge， study group scored lower on HAMD-24 and HAMA compared to control group （t=0.210， 0.720， P<0.05）. At the end of 2 weeks of treatment， study group resulted in greater improvements in depressive symptoms and anxiety symptoms than those of control group （95.14% vs. 66.30%， 89.18% vs. 71.74%， χ²=78.942， 22.526， P<0.05）. The overall efficacy rate yielded no statistical difference between two groups at end of the 2^nd week after discharge （P>0.05）， and no statistical difference was found in the adverse reactions between the two groups （P>0.05）. ConclusionCompared with sertraline alone， its combination with relaxation therapy may achieve a better short-term efficacy in the treatment of depressive episode in children and adolescents. ［Funded by Sichuan Medical Scientific Research Project （number， S18020）］

Objective:To observe the features of Henle fiber layer (HFL) in eyes with central serous chorioretinopathy (CSC) using spectral domain optical coherence tomography (SD-OCT).Methods:A cross-sectional study was conducted.Thirty-five CSC patients (35 eyes) treated in the Third People's Hospital of Qingdao from January 2017 to November 2021 were enrolled.The subjects included 23 males (23 eyes) and 12 females (12 eyes), aged 24 to 60 years old, with an average age of (41.14±8.19) years, and had a CSC duration ranged from 1 day to 6 months.SD-OCT was performed on all eyes with a line scan through the central fovea horizontally.The features of HFL over subretinal fluid (SRF) area were analyzed and summarized.The study protocol adhered to the Declaration of Helsinki and was approved by the Ethics Committee of the Third People's Hospital of Qingdao (No.2022Y0403001).Results:In 26 eyes with regular dome-shaped neurosensory retinal detachment, HFL appeared to be delimited type 1 in 25 eyes, accounting for 96.15%, delimited type 2 in 7 eyes, accounting for 26.92%, bright in 17 eyes, accounting for 65.38% over SRF area.In 21 eyes with CSC duration≤21 days, HFL all showed delimited type 1 and some presented bright or delimited type 2 at the same time.In 5 eyes with CSC duration>21 days, HFL all showed bright and some were delimited type 1 or delimited type 2 in the meantime.In 15 eyes with symmetrical nasal and temporal retinal detachment, HFL showed symmetrical reflectivity over SRF area in horizontal OCT images in 6 eyes, and showed brighter reflectivity over nasal SRF in nasal elevated OCT images in 3 eyes and over temporal SRF in temporal elevated OCT images in 6 eyes.In 11 eyes with asymmetrical nasal and temporal retinal detachment, HFL showed brighter reflectivity over temporal SRF with larger retinal detachment range on temporal side in horizontal OCT images in 3 eyes.Of the 4 eyes with nasal elevated OCT images, the retinal detachment range was larger on temporal side and HFL showed symmetrical reflectivity over SRF area in 3 eyes, and HFL was brighter over nasal SRF area with larger retinal detachment range on nasal side in 1 eye.Of the 4 eyes with temporal elevated OCT images, the retinal detachment range was larger on nasal side and HFL showed symmetrical reflectivity over SRF area in 3 eyes, and HFL was brighter over nasal SRF area with larger retinal detachment range and higher height on nasal side in 1 eye.In 9 eyes with irregular neurosensory retinal detachment, HFL appeared to be delimited type 1 in 7 eyes, accounting for 77.78%, delimited type 2 in 5 eyes, accounting for 55.56%, bright in 6 eyes, accounting for 66.67%, dark in 4 eyes, accounting for 44.44%, and indistinct in 2 eyes, accounting for 22.22%.The detached neurosensory retina was not smooth in 7 eyes, and the phenotypes of HFL changed with the directions of detached neurosensory retina.In 2 eyes with only low neurosensory retinal detachment, HFL reflectivity on the raised side was slightly weaker than that on the lowered side.Conclusions:HFL appears to be delimited type 1 and bright mostly over SRF area in CSC in SD-OCT images.The phenotypes of HFL vary regularly with the tilt directions of OCT images, CSC duration, and the symmetry, range, height, directional characteristics of detached neurosensory retina.

Objective:To investigate the application effect of case-based learning (CBL) combined with flipped classroom in the teaching of experimental diagnostics in the integrated course of Diagnosis and Treatment Fundamentals. Methods:The cluster random sampling method was used to select the class of 2019 in the eight-year program and the class of 2020 in the five-year program, with the major of stomatology in Air Force Medical University. The 24 students in the observation group received CBL combined flipped classroom, and the 37 students in the control group received traditional teaching. The two groups were compared in terms of theoretical assessment score, classroom assessment score, comprehensive ability, self-learning ability, and degree of satisfaction with teaching. SPSS 22.0 was used for the t-test. Results:The observation group had a significantly higher theoretical assessment score than the control group [(74.88±3.46) vs. (71.89±4.45), P<0.05]. The observation group had significantly better scores of practical skill assessment than the control group ( P<0.05). Compared with the control group, the observation group had significantly better scores of comprehensive ability and self-learning ability ( P<0.05). The observation group had significantly better scores of satisfaction with teaching than the control group ( P<0.05). Conclusion:The application of CBL combined with flipped classroom in the teaching of experimental diagnostics in the integrated course of Diagnosis and Treatment Fundamentals can improve theoretical knowledge, practical skills, comprehensive quality, and satisfaction with teaching among students, and therefore, it holds promise for application in teaching.

Objective:To investigate the clinical and pathological features, treatment, and prognosis of gray zone lymphoma (GZL) .Methods:From July 2, 2013, to February 10, 2021, the clinical and pathological features, treatment, and outcomes of five patients with GZL at the Blood Diseases Hospital, Chinese Academy of Medical Sciences were studied retrospectively.Results:There were one male and 4 females, with a median age of 28 (16-51) years at diagnosis. Four patients had mediastinal (thymic) involvement, two of which had superior vena cava obstruction syndrome, and 3 patients had extra-nodal involvement. There was one case with a limited Ann Arbor stage and 4 cases with a progressive stage. Three patients had cHL-like pathomorphology with scattered Hodgkin-like cells, strongly positive for CD20, positive for CD30, and CD15 was negative; the other two patients had both cHL and DLBCL morphology, with some areas resembling Hodgkin cells and some areas resembling immunoblasts, strongly positive for CD30, and CD15 but negative CD20. Two patients were treated with cHL-like regimens for induction and achieved only partial remission; after salvage therapy with enhanced DLBCL-like regimens, all achieved complete remission (CR) . Three patients were treated with enhanced DLBCL-like immunochemotherapy regimens for induction, and two patients were effective, one of whom achieved CR. Four patients who did not achieve CR were given second or third-line salvage therapy, and all of them recovered. One patient lost parity, one died of disease progression at 35.9 months after diagnosis, and the remaining three maintained sustained remission.Conclusions:GZL is uncommon, usually affects younger patients, is mediastinal and is diagnosed using path morphology and immunophenotype. Patients with newly diagnosed GZL appear to be more sensitive to DLBCL-like immunochemotherapy regimens; relapsed or refractory patients were tended with non-cross-resistant combination chemotherapy or with new drugs.
