BACKGROUND:Transcranial magneto-acoustic-electrical stimulation is a novel non-invasive neural regulation technique that utilizes the induced electric field generated by the coupling effect of ultrasound and static magnetic field to regulate the discharge activity of the nervous system.However,the mechanism by which it affects synaptic plasticity in the brain is still not enough. OBJECTIVE:To explore the effect of transcranial magneto-acoustic-electrical stimulation intensity on synaptic plasticity of the prefrontal cortex neural network in mice. METHODS:(1)Animal experiment:Twenty-four C57 mice were equally and randomly divided into four groups:the control group receiving pseudo-stimulation,the 6.35 W/cm2 stimulation group receiving coupled stimulation of 0.3 T,6.35 W/cm2,the 17.36 W/cm2 stimulation group receiving coupled stimulation of 0.3 T,17.36 W/cm2,and the 56.25 W/cm2 stimulation group receiving coupled stimulation of 0.3 T,56.25 W/cm2.The local field potential signals and behavioral correctness were recorded during the execution of T-maze in mice.(2)Modeling and simulation experiments:A neural network model of the prefrontal cortex in mice stimulated by transcranial magneto-acoustic-electrical stimulation was constructed to compare the structural connectivity characteristics of the neural network under different stimulation intensities. RESULTS AND CONCLUSION:Transcranial magneto-acoustic-electrical stimulation could effectively shorten the behavior learning time,improve the working memory ability of mice(P<0.05),and continue to stimulate the frontal lobe of mice after learning behavior.There was no significant difference in the accuracy of the T-maze behavioral experiment among the experimental groups(P>0.1).Analysis of local field potential signals in the frontal lobe of mice revealed that transcranial magneto-acoustic-electrical stimulation promoted energy enhancement of β and γ rhythms.As the stimulation intensity increased,there was an asynchronous decrease in β and γ rhythms.Through β-γ phase amplitude coupling,it was found that stimuli could enhance the neural network's ability to adapt to new information and task requirements.Modeling and simulation experiments found that stimulation could enhance the discharge level of the neural network,increase the long-term synaptic weight level,and decrease the short-term synaptic weight level only when the stimulation intensity was high.To conclude,there is a complex nonlinear relationship between different stimulus intensities and the functional structure of neural networks.This neural regulation technique may provide new possibilities for the treatment of related neurological diseases such as synaptic dysfunction and neural network abnormalities.

OBJECTIVE:
To investigate the clinical characteristics and prognosis of patients with IgD multiple myeloma (MM).
METHODS:
The clinical data of 8 patients with IgD MM admitted to Gansu Provincial Hospital from September 2013 to February 2023 were collected, and their clinical characteristics and prognosis were retrospectively analyzed and summarized.
RESULTS:
Among the 8 enrolled patients, there were 4 males and 4 females, with a median age of 60 (44-74) years. All patients had symptoms of renal insufficiency and anemia. There were 3 cases of bone invasion, 3 cases of splenomegaly, 7 cases of IgD-λ type, and 1 case of IgD-κ type. FISH examination was performed in 7 cases, and 6 of them were positive for 1q21 . There were 6 cases in DS stage III and 2 cases in DS stage II; According to ISS staging, there were 6 cases in stage III, 1 case in stage II, and 1 case in stage I; According to R-ISS staging, there were 5 cases in stage III and 3 cases in stage II. All patients received bortezomib-based combination chemotherapy, with 1 case undergoing autologous stem cell transplantation (ASCT) and 2 cases receiving daratumumab in combination. The median treatment period was 6 (1-15) cycles. The short-term efficacy was evaluated after 4-6 courses of treatment. Among the 6 patients with assessable efficacy, 1 case experienced disease progression (PD), and 5 cases achieved complete remission (CR). The median follow-up time was 26 (11-33) months, and the median progression-free survival (PFS) and median overall survival (OS) of the patients were 11.25 (3-26) months and 18.5 (4-33) months, respectively. Among the 8 patients, 4 cases died. Among the deceased patients, 3 cases were in R-ISS stage III and 3 cases were 1q21 positive. 2 of the 5 patients with early CR died due to disease progression.
CONCLUSION
The incidence of IgD MM is low, the symptoms of early renal damage, blood system damage and bone erosion in IgD MM patients are obvious, and the median survival time is short. ASCT and / or daratumumab may bring lasting relief for IgD MM patients, but large-scale clinical studies are still needed.

OBJECTIVE:
To analyze the clinical characteristics and prognosis of patients with T-cell large granular lymphocytic leukemia (T-LGLL).
METHODS:
The clinical data of 7 patients with T-LGLL in Gansu Provincial Hospital from March 2016 to June 2023 were analyzed retrospectively.
RESULTS:
Among the 7 patients, 5 were male and 2 were female, with a median age of 51(28-83) years old. At the onset of illness, 6 cases showed symptoms of fatigue and anemia, 4 cases had enlarged lymph nodes, and 5 cases had splenomegaly. Examination showed that 4 cases were antinuclear antibody(ANA) positive, 5 cases were anemia. The median hemoglobin (Hb) level was 83(61-151) g/L, the median white blood cell count (WBC) was 5.6(2.0-8.7)×109 /L, and the median percentage of lymphocytes in peripheral blood was 66.2(13.9-89.1)%. There were 3 cases with extremely active bone marrow hyperplasia, 2 cases with active hyperplasia, and 2 cases with decreased hyperplasia. There were 5 cases with mild myelofibrosis (MF-1), and 1 case with moderate myelofibrosis (MF-2). The median percentage of T cells was 64.3 (31.5-80.6)%. 5 cases showed the classic immunophenotype (CD3 + CD4- CD8 +), 6 cases were CD57 +, 3 cases were TCRα/β +, and 3 cases were TCRγ/δ +. TCRG rearrangement was detected in 5 cases.The median follow-up time was 55(4-87) months, one patient died of heart disease, and the other 6 patients are surviving.
CONCLUSION
The incidence of T-LGLL is low. The initial symptoms of T-LGLL include anemia, fatigue, lymph node enlargement, splenomegaly, and higher percentage of lymphocytes in peripheral blood, the percentage of abnormal T cells in bone marrow was significantly increased. Analysis of flow cytometric immunophenotyping, TCR gene rearrangement, and hot spot genes such as STAT3 and STAT5b, can improve the diagnostic accuracy.

ObjectiveTo explore the influence of electroacupuncture combined with point bloodletting and cupping for facial nerve function recovery in acute stage of idiopathic facial palsy (IFP). MethodsEighty patients with IFP in the acute stage were randomly divided into 40 cases each in the treatment group and the control group. In the control group, oral prednisone acetate tablets were administered during the acute stage when the disease duration was less than 10 days; and electroacupuncture and flash cupping were provided during the recovery stage when the disease duration was more than 10 days, five times a week. For treatment group in acute stage, the stellate ganglion, vagus nerve stimulation point in the auricular cavity, Yifeng (TE 17) and Tinghui (GB 2) were needled on the affected side on the basis of the treatment of control group, with Yifeng and Tinghui connecting to electroacupuncture apparatus, once a day; point bloodletting and then cupping in Yifeng 2 times a week; in recovery stage, the treatment was the same as that of the control group. Both groups were treated until the 45th day from onset. The primary outcome was the Toronto facial grading system (SFGS), and the secondary outcomes included house-brackmann (H-B) grade, facial disability index (FDI) score, and number of H-B grade-Ⅰ cases. Adverse events were recorded in both groups. ResultsThe SFGS scores of the patients in both groups were higher on the 10th, 30th and 45th days after onset of disease compared with those before the treatment (P<0.05); the H-B grade was lower on the 30th and 45th days after the onset of the disease compared with those before the treatment (P<0.05); and the facial disability index physical function (FDIP) and facial disability index social function (FDIS) scores were higher on the 30th and 45th days after onset of disease (P<0.05). SFGS scores of patients in the treatment group were significantly higher than those of the control group on the 30th and 45th days after onset (P<0.05); H-B grade was significantly lower than that of the control group on the 30th and 45th days after onset (P<0.05); and FDIP scores on the 45th day after onset, and FDIS scores on the 30th and 45th days after onset were significantly higher than those of the control group (P<0.05). At the end of treatment, 77.50% (31 cases) achieved H-B grade-Ⅰ in the treatment group, which was more than 55.00% (22 cases) in the control group (P<0.05). No adverse events occurred in either group. ConclusionElectroacupuncture combined with point bloodletting and cupping for IFP in acute stage can improve the recovery degree of facial nerve function, improve effectiveness, and show a high degree of safety.

Objective:
To explore the effects of different positions, epoch lengths and cut points of accelerometers on the measurement of sedentary behaviour (SB), light physical activity (LPA) and moderate vigorous physical activity (MVPA) in school aged children, so as to provide a reference for optimizing the criteria of accelerometers to measure SB and physical activity in school aged children.
Methods:
From May 2021 to September 2022, 110 school aged children aged 8-12 years old were convenient selected from a primary school in Hangzhou, and the accelerometers were worn on the waist, back, thigh, and wrist during the school time, and the collected data were transformed into six datasets with different epoch lengths (1, 5, 10, 15, 30, and 60 s) and compared using 4 common cut points developed by Puyau, Freedson, Evenson, and Pulsford (a total of 96 combinations) for classifying the percentages of time spent in SB, LPA, and MVPA. The effects of different positions, epoch lengths and cut points and their interactions on the assessment results were analyzed using a three way repeated measures ANOVA, and the variability of multiple comparisons between groups was analyzed using a Bonferroni post hoc test.
Results:
Except for the interaction of cut point × position × epoch on the percentage of time spent in SB and the main effect of epoch on he percentage of time spent in MVPA were not statistically significant ( F =0.66,1.18, P >0.05), the remaining main effects and interactions of the three factors on the assessment results were all statistically significant ( F =6.28-11 662.28, P <0.01). The differences between the results of different positions were statistically significant ( F =90.98-308.79, P <0.01). The percentages of time spent in SB and MVPA decreased with the increase of epoch lengths, while the percentage of time spent in LPA increased with the increase of epoch lengths ( F =16.54- 676.35 , P <0.01). The difference between the results using different cut points measurements was statistically significant ( F = 98.14- 976.40, P <0.01).
Conclusions
Accelerometer methodological factors including positions, epoch lengths and cut points will affect the estimates of SB and physical activity in school aged children. Therefore, it is recommended that future studies need to optimize the applicability of accelerometer analysis methods in school aged children, and the comparisons of results between studies need to be treated with caution.

Myocardial fibrosis (MF) is a common pathological manifestation of various heart diseases. Due to the non-renewable nature of myocardial cells, the occurrence of MF represents irreversible damage to the myocardium. Previous studies have suggested that fibroblast-mediated collagen deposition is the main mechanism of MF. Recent studies have found that there is an immune regulation mechanism in the heart itself, and macrophage activation/polarization plays an important role in MF. With the deepening of traditional Chinese medicine research, scholars have found that traditional Chinese medicine can interfere with MF by regulating the renin-angiotensin-aldosterone system (RAAS) system and the inflammatory process, repairing the extracellular matrix, managing oxidative stress, and maintaining the balance of autophagy. This process is closely related to the activation and M1/M2 polarization of macrophages. Throughout the MF process, macrophage activation is beneficial, but excessive activation will be harmful. In the early stage of MF, appropriate M1 macrophage polarization is conducive to activating immunity and removing harmful substances. In the middle and late stages of MF, appropriate M2 macrophage polarization is conducive to remodeling the damaged myocardium. If macrophage activation is excessive/insufficient, or the balance of M1/M2 macrophage polarization is broken, the effect changes from improvement to destruction. Traditional Chinese medicines that regulate the activation/polarization of macrophages have the effects of replenishing Qi and nourishing Yin, as well as regulating Qi and activating blood, but there are also some heat-clearing, dampness-drying, and detoxification products. Therefore, the occurrence of MF may be caused by Qi and Yin deficiency, damp heat accumulation, and Qi stagnation and blood stasis. By summarizing the biological processes involved in macrophage activation/polarization in MF, this paper expounded on the research progress of traditional Chinese medicine in regulating macrophage activation and M1/M2 polarization from different angles to improve MF, so as to provide a reference for the treatment of MF with traditional Chinese medicine.

Objective:To explore the latent profile types of capability-opportunity-motivation-behavior in stroke patients and analyze the influencing factors of different latent profiles.Methods:From January to October 2023, totally 596 stroke patients from the Neurology Department of five ClassⅢ Grade A hospitals in Henan Province were selected by stratified random sampling. The patients were surveyed using a general information questionnaire, the Stroke Prevention Knowledge Questionnaire (SPKQ), the Social Support Rating Scale (SSRS), the WHO's Quality of Life Questionnaire- Brief Version (WHOQOL-BREF), the Short Form Health Belief Model Scale (SF-HBMS), and the Health Promoting Lifestyle ProfileⅡ (HPLPⅡ). Latent profile analysis was used to classify the capability-opportunity-motivation-behavior characteristics of stroke patients, and multiple logistic regression was conducted to explore the influencing factors of different latent profiles.Results:Three latent profiles of capability-opportunity-motivation-behavior in stroke patients were identified, including low capability-opportunity-motivation-behavior with high health beliefs (32.4%, 193/596), moderate capability-opportunity-motivation-behavior with insufficient health beliefs (47.5%, 283/596), and high capability-opportunity-motivation-behavior with lack of social support (20.1%, 120/596). Multiple logistic regression analysis showed that educational level, smoking history, family history, body mass index, and Charlson Comorbidity Index score were influencing factors of different latent profiles ( P<0.05) . Conclusions:Stroke patients exhibit distinct classifications of capability-opportunity-motivation-behavior. Targeted interventions should be conducted based on the characteristics of each category to improve health behavior management outcomes in patients.

Objective:To explore the mediating effect of rumination between self-perceived burden (SPB) and stigma in stroke patients, so as to provide theoretical basis for the development of targeted nursing interventions in clinical practice.Methods:In September 2022, cluster sampling was used to select 1 126 stroke patients admitted to Department of Neurology of five ClassⅢ Grade A hospitals in Henan Province as subjects. General Information Questionnaire, Self-Perceived Burden Scale (SPBS), Stroke Stigma Scale (SSS), and Chinese Version of Event Related Rumination Inventory (C-ERRI) were used to investigate stroke patients. Pearson correlation analysis was used to explore the correlation between SPB, rumination, and stigma. AMOS 28.0 software was used to establish the structural equation model, and Bootstrap method was used to test the mediating effect.Results:A total of 1 126 questionnaires were distributed, and 1 026 valid questionnaires were collected, with a valid response rate of 91.12% (1 026/1 126). SPBS score of 1 026 stroke patients was (28.68±8.32), the SSS score was (40.53±9.48) and the C-ERRI score was (25.43±12.62). Pearson correlation analysis showed that SPB in stroke patients was positively correlated with stigma and rumination ( P<0.01), and rumination was positively correlated with stigma ( P<0.01). Bootstrap mediating effect test showed that rumination partially mediated the relationship between SPB and stigma in stroke patients, accounting for 55.15% of the total effect. Conclusions:SPB of stroke patients both directly affect stigma and indirectly affect stigma through rumination. Clinical nursing workers should promptly evaluate patients' SPB, pay attention to the mediating role of rumination, develop effective psychological intervention programs, implement personalized and targeted nursing measures, relieve patients' stigma, and improve treatment and rehabilitation compliance.
