Objective:To summary the clinical and electrophysiological characteristics of temporal lobe epilepsy (TLE) originating from the temporal pole (TP), and to conduct brain network analysis based on stereo-electroencephalogram (SEEG) and head positron emission tomography- computed tomography (PET-CT).Methods:A retrospective analysis was conducted on patients with TLE who underwent SEEG implantation from January 1, 2019 to September 1, 2023 in Guangdong Sanjiu Brain Hospital. Based on anatomical-electrical-clinical analysis and SEEG findings, patients with seizures originating from the TP were selected. The clinical data, head magnetic resonance imaging (MRI), PET-CT, scalp electroencephalogram were reviewed, and the seizure-induced network was analyzed based on SEEG and head PET-CT.Results:A total of 108 cases of TLE were analyzed, of whom 13 cases had an epileptogenic zone located at the TP, accounting for 12% (13/108) of all TLE patients. Among them, 8 were males and 5 were females, and age of onset was (11.6±7.8) years. All of them were drug-resistant epilepsy patients, of whom 6 cases had normal cognitive function, 4 had mild cognitive abnormalities, and 3 had severe cognitive decline. A total of 59 seizures were recorded, and the occurrence rate of generalized tonic-clonic seizures (GTCS) was 42% (25/59). Seizure symptoms were classified into 3 types: the first type was hypermotor, seen in 9 patients; the second type was complex motor, seen in 2 patients; and the third type was automotor, seen in 2 patients. Head MRI showed that 9 cases had a blurring of the TP on one side, with or without hippocampal sclerosis; 2 cases had a mass at the TP without hippocampal sclerosis; 2 cases were negative on head MRI. Head PET-CT showed that 13 cases had TP hypometabolism on the lesion side, of whom 11 cases had hypometabolism involving the medial temporal lobe (mTL), posterior orbital gyrus (POG), anterior cingulate gyrus (ACG) and insular lobe at the same time, the other 2 cases combined with ipsilateral hypometabolism of the medial temporal lobe. Pathology showed that 7 cases had microcortical dysplasia of the TP; 3 had focal cortical dysplasia Ⅰ or focal cortical dysplasia Ⅱ; 2 had benign tumors. Scalp electroencephalogram showed that interictal phase was divided into 3 discharge patterns: bilateral temporal regions with prominent lesion side; bilateral anterior regions with prominent lesion side; lesion-side hemisphere with prominent temporal region. Ictal period showed 4 initial patterns: lesion-side hemispheric rhythmic spikes-slow waves or polyspikes-slow waves; lesion-side anterior region rhythmic slow waves; lesion-side anterior region low voltage fast (LVF) activities, and diffuse LVF with prominent lesion-side hemisphere. SEEG showed that 13 patients received electrode implantation with (9±2) electrodes per patient, divided into 3 seizure patterns: type 1: TP?adjacent temporal neocortex?POG, ACG and insula?mTL; type 2: TP?para hippocampal gyrus and the base of temporal lobe?ACG ,POG and insula?mTL; type 3: TP?mTL?insular lobe?POG.Conclusions:TLE originating from the TP is relatively rare, with hypermotor or complex motor as the main manifestations, and automotor being relatively less common, which is more likely to be followed by GTCS. The epileptogenic network analysis displays a tendency to spread from the TP to the frontal and insular lobes, as well as to the mTL, with the former pattern being more common. Common etiologies are cortical dysplasia and benign tumors of the TP without hippocampal sclerosis.

Objective:To explore the epileptogenic network patterns in 14 patients with mesial temporal lobe epilepsy (mTLE) originating from the amygdala.Methods:A total of 14 patients with mTLE originating from the amygdala underwent preoperative evaluation in Department of Epilepsy, Guangdong Sanjiu Brain Hospital from January 1, 2019 to December 31, 2023 were selected. A retrospective analysis was performed on the clinical data of these patients. Epileptogenic network patterns were further explored based on stereo-electroencephalogram (SEEG) and positron emission tomography-computed tomography (PET-CT).Results:Craniocerebral MRI indicated 12 patients with unilateral amygdala hypertrophy, and 2 with increased T2-FLAIR signal in the amygdala but no obvious volume change. During interictal period, scalp EEG indicated discharges in one or both temporal regions and distinguished at the lesion side. During ictal period, scalp EEG indicated that the initial side is consistent with the lesion side. Three clinical phenotypes and epileptogenic network patterns were summarized: the first type ( n=5) had clinical manifestations as aura→automotor→autonomic symptoms, with epileptic seizure starting from amygdala→hippocampus→preinsula→temporal pole (by SEEG) and low metabolism in the medial structures of the temporal lobe (by PET-CT); the second type ( n=6) had clinical manifestations as aura→hypermotor/complex motor→autonomic symptoms, with epileptic seizure starting from amygdala→hippocampus→temporal pole→frontal orbital gyrus and anterior cingulate cortex→insula (by SEEG) and low metabolism in the medial structures of the temporal lobe, temporal pole, insula, frontal-orbital gyrus, and inner frontal lobe (by PET-CT); the third type ( n=3) had clinical manifestations as aura→bilateral symmetrical dystonia→autonomic symptoms (with or without oral-alimentary automotor), with epileptic seizure starting from amygdala→hippocampus and insula→temporal pole and adjacent temporal neocortex (by SEEG) and low metabolism in the mesial structures of the temporal lobe and the insula (by PET-CT). Conclusion:The different clinical phenotypes of patients with mTLE originating from the amygdala may have equivalent epileptogenic network patterns.

Objective:To investigate the effects of dietary management during labor process on pregnancy outcome of pregnant women with gestational diabetes mellitus.Methods:A retrospective analysis was conducted on the clinical data of 122 pregnant women with gestational diabetes mellitus who delivered at the Wenzhou People's Hospital between January and December 2022. Based on their dietary management methods, these patients were divided into an observation group and a control group, with 61 cases in each group. The control group underwent routine dietary management, whereas the observation group received dietary management during labor process. The labor process indicators and delivery outcomes between the two groups were compared.Results:The energy intake in the observation group was (75.36 ± 9.54) kcal/h, which was significantly higher than (57.23 ± 8.12) kcal/h in the control group ( t = -11.30, P < 0.05). Furthermore, the highest blood glucose levels, hyperglycemia ratios, and proportions of insulin usage in the observation group were (6.74±0.99) mmol/L, 4.92% (3/61), and 3.28% (2/61), respectively, which were significantly lower than those in the control group [(7.72 ± 1.05) mmol/L, 40.98% (25/61), 21.31% (13/61), t = 5.30, χ2 = 22.43, 9.20, all P < 0.05]. Additionally, the observation group had significantly shorter first stage labor time [(418.66 ± 114.26) minutes], active stage time [(281.37 ± 129.65) minutes], and second stage labor time [38.14 ± 17.25) minutes] compared with the control group [(519.93 ± 132.45) minutes, (358.69 ± 153.26) minutes, (51.37 ± 18.62) minutes, t = 4.52, 3.00, 4.07, all P < 0.05]. The incidence of neonatal hypoglycemia in the observation group was 1.64% (1/61), which was significantly lower than 16.39% (10/61) in the control group ( χ2 = 6.39, P < 0.05). Conclusion:Dietary management during the labor process can effectively improve the blood sugar level of pregnant women with gestational diabetes mellitus, as well as enhance the maternal and fetal outcomes.

Objective To explore the efficacy and safety of omalizumab in the treatment of allergic bronchopulmonary aspergillosis(ABPA).Methods The clinical data of 26 ABPA patients treated with omalizumab in Zhongshan Hospital,Fudan University from November 2018 to December 2023 and 24 ABPA patients treated with prednisone combined with itraconazole in the same period were analyzed retrospectively.The primary outcomes were exacerbation times and oral corticosteroid-sparing effect.The secondary outcomes were respiratory symptoms,circulating eosinophil count,total immunoglobin E(IgE)level,specific IgE for aspergillus,pulmonary function(the percentage value of forced expiratory volume in one second predicted[FEV1%pred]),fraction of exhaled nitric oxide(FeNO),thoracic computed tomography(CT)manifestation and adverse reactions.Results In omalizumab group,the exacerbation times of ABPA after 6 and 12 months of treatment were 0(0,0)times/6 months and 0(0,1)times/6 months,there was no significant difference(P=0.157),which were significantly lower than those of the baseline(1[1,2]times/6 months,P＜0.001).The oral dose of prednisone decreased from 10(5,15)mg/d(before treatment)to 3.125(0,5)mg/d(6 months after treatment,P＜0.001).After 12 months of treatment,the oral dose of prednisone was 0(0,3.125)mg/d,which was significantly lower than that of the baseline dose(P=0.003).After treatment with omalizumab for 12 months,the FeNO level decreased significantly(26[13,36]×10﹣9 vs 30[18,56]×10﹣9,P=0.049).There was no significant difference in blood eosinophil count,total IgE level,specific IgE for aspergillus and FEV1%pred before and after omalizumab treatment.After 6 months of treatment with omalizumab,respiratory symptoms were relieved in 23 patients(88.5%)and radiographic improvement was achieved in eight out of sixteen patients(50%)with mucus plugs.More patients successfully discontinued oral prednisone when treated with omalizumab for 12 months than those in control group(P=0.035).During the treatment of omalizumab,4(15.4%)patients had a slight increase in alanine aminotransferase(ALT),and 1 patient was complicated with hepatocellular carcinoma during follow-up.Conclusions Omazumab treatment can effectively reduce the number of acute episodes of ABPA,reduce the dosage of oral glucocorticoids,improve FeNO,facilitate the absorption of mucus plugs,and has high safety.

Objective:To introduce and validate the Pediatric Nausea Assessment Tool (PeNAT) and the Baxter Retching Faces Scale (BARF) in the assessment of chemotherapy induced nausea in Chinese children with malignant neoplasms, and to explore the cut-off value for rescue antiemetic.Methods:A prospective descriptive study was conducted, 244 children in Sun Yat-sen University Cancer Center with malignant neoplasms who received chemotherapy were selected by convenience sampling from July to August 2021. PeNAT, BARF, Visual Analogue Scale (VAS) and the Faces Pain Scale-Revised(FPS-R) were used to assess the severity of nausea and pain before and after chemotherapy, before and 30-60 minutes after the use of rescue antiemetic or analgesic. After chemotherapy, the children also were asked the changes of nausea severity and whether antiemetic was needed.Results:A test-retest reliability was conducted on the patients with the same severity of nausea before and after chemotherapy, and the intraclass correlation coefficient of the PeNAT and BARF were 0.940 (both P<0.05). After chemotherapy, the PeNAT and BARF were 1.5(1.0, 2.0) and 2.0(0, 2.0) points, which were significantly higher than the 1.0(1.0, 1.0) and 0(0, 0) points before chemotherapy ( Z = - 9.19, - 9.09, both P<0.01). The PeNAT and BARF of 11 cases receiving antiemetic before medication were 4.0 (4.0, 6.0) and 3.0(2.0, 4.0) points, which were higher than the 0(0, 2.0) and 1.0(1.0, 2.0) points without antiemetic ( Z = - 4.03, - 3.86, both P<0.05). After chemotherapy, the correlation coefficients between PeNAT or BARF and VAS-nausea were r = 0.933, 0.957 (both P<0.01), and FPS-R were r = 0.192, 0.189 (both P<0.05). After using antiemetic, PeNAT and BARF were 2.0(2.0, 3.0) and 2.5(2.0, 4.0) points, which were significant different than the 3.0(3.0, 3.8) and 4.0(4.0, 8.0) points before using antiemetic ( Z = - 2.97, - 2.83, both P<0.05). According ROC curves and cut-off values, it was determined that PeNAT≥3 and BARF≥4 had clinical significance and require clinical intervention. Conclusions:PeNAT and BARF have excellent reliability and validity in the assessment of chemotherapy induced nausea in children with malignant neoplasms, they can effectively identify the requirement of rescue antiemetic, and evaluate the efficacy of antiemetic.

Objective:To explore the risk factors of bortezomib-related peripheral neuropathy (BIPN) and the clinical and electrophysiological characteristics of patients in treatment of multiple myeloma (MM).Methods:The clinical data of 71 newly diagnosed MM patients treated with BD (bortezomib + dexamethasone) regimen in Yancheng First People's Hospital from March 2016 to December 2019 were retrospectively analyzed. The bone marrow morphology, immunology, cytogenetics, molecular biology (MICM), routine electrophysiological examination before and after treatment were performed. All patients were divided into the peripheral neuropathy (PN) group and the non-PN group according to the presence or not of BIPN, and the clinicopathological differences of both groups were also compared; a binary logistic regression model was used to analyze the factors affecting the occurrence of PN. The electrophysiological characteristics were summarized and fluorescence in situ hybridization (FISH) was used to detect karyotype of BIPN patients.Results:Among 71 MM patients, there were 40 cases (56.3%) of PN and 31 cases (43.7%) of non-PN. The proportion of patients at international staging system (ISS) staging Ⅲ, and the levels of IgA, IgG, IgM, serum creatinine, β 2-microglobulin (β 2-MG) in the PN group were higher than those in the non-PN group, and hemoglobin (Hb) level in the PN group was lower than that in the non-PN group, and the differences were statistically significant (both P < 0.05). Binary logistic regression analysis showed that increased IgA ( OR = 1.151, 95% CI 1.012-1.309, P = 0.033), increased IgG ( OR = 1.055, 95% CI 1.000~1.112, P = 0.049), increased IgM ( OR = 1.010, 95% CI 1.001-1.018, P = 0.022), increased serum creatinine ( OR = 1.037, 95% CI 1.011~1.065, P = 0.005), increased β 2-MG ( OR = 1.564, 95% CI 1.039-2.354, P = 0.032) were risk factors for BIPN. Among 40 patients with BIPN, 33 cases (82.5%) of sensory nerve conduction velocity (SCV) were abnormal, 23 cases (57.5%) of motor nerve conduction velocity (MCV) were abnormal; 31 cases (77.5%) showed demyelination damage, 9 cases (22.5%) had axonal damage. Among 40 patients with BIPN, 24 cases underwent FISH detection, including 19 cases (79.2%) with chromosomal mutations, of which 12 cases (50.0%) were mixed subtype abnormal. Conclusions:MM patients with high levels of β 2-MG, IgA, IgG, IgM and serum creatinine are more prone to PN when treated with bortezomib. The electrophysiology of patients with BIPN is mainly characterized by demyelination of sensory nerves.

ObjectiveTo reveal the targets and molecular mechanisms of the action of Qiangxin Decoction （强心汤） for the treatment of chronic heart failure based on the combination of network pharmacology and molecular docking. MethodsThe active ingredients of Qiangxin Decoction were retrieved from TCMSP database， and the targets of chronic heart failure were screened by searching GeneCards， OMIM， TTD， PharmGkb， and DrugBank databases， and the intersections were taken to obtain the intersecting targets of Qiangxin Decoction for the treatment of chronic heart failure. STRING platform was used to construct the protein-protein interaction network （PPI）， Cytoscape 3.8.0 software was used to calculate the network topology to screen the core targets， and R 4.2.3 was used to construct the “active ingredient-target” network by analyzing the GO enrichment analysis and KEGG pathway enrichment analysis. AutoDock 1.5.7 was used for molecular docking to predict the binding performance of active ingredients and core targets. ResultsSeventy-five intersecting targets were identified for the treatment of chronic heart failure with Qiangxin Decoction， among which the core targets were estrogen receptor 1 （ESR1， degree value=7）， nuclear receptor coactivator 1 （NCOA1， degree value=8）， glucocorticoid receptor （NR3C1， degree value=7）， and nuclear receptor coactivator 2 （NCOA2， degree value=7）. GO enrichment analysis showed that the top 3 items with the smallest P value in molecular function were G protein-coupled amine receptor activity， postsynaptic neurotransmitter receptor activity， and neurotransmitter receptor activity （P＜0.01）； the top 3 items with the smallest P value in biological process were adenylyl cyclase-activated adrenergic receptor signaling pathway， adrenergic receptor signaling pathway， and adenylyl cyclase-regulated G protein-coupled receptor signaling pathway （P＜0.01）； the top 3 items with the smallest P values in cellular composition were components of the postsynaptic membrane， synaptic membrane， and presynaptic membrane （P＜0.01）. KEGG enrichment analysis showed that the top 5 key signaling pathways were neuroactive ligand-receptor interactions， calcium signaling pathway， dopaminergic synapses， cocaine addiction， and cyclic guanosine monophosphate-protein kinase G （cGMP-PKG） signaling pathway. The molecular docking results showed that lignans and isoflavones had lower binding energies and more structural stability with the four core targets （ESR1， NCOA1， NR3C1， NCOA2）. ConclusionThe treatment of chronic heart failure by Qiangxin Decoction was associated with neuroactive ligand-receptor interactions， calcium signaling pathway， dopaminergic synapses， chemoattractant-receptor activation， cGMP-PKG signaling pathway， lipids and atherosclerosis， and cAMP signaling pathway， and lignans and isoflavones may be the core active compounds in its treatment of chronic heart failure.

Objective:To investigate the clinicopathological features, diagnosis, differential diagnosis and treatment of nodal marginal zone lymphoma (NMZL) with elevated monoclonal IgM.Methods:The clinical data of one NMZL patient with elevated monoclonal IgM treated at Yancheng No.1 People's Hospital in July 2020 were retrospectively analyzed, and the related literature was analyzed.Results:The patient was a 57-year-old female and the main clinical manifestations were fatigue and bone pain in left rib. Serum immunofixation electrophoresis showed IgM-κ type M proteinemia, bone marrow cytology showed a few plasmacytoid lymphocytes, bone marrow biopsy and immunohistochemistry showed B-cell non-Hodgkin lymphoma, bone marrow genetic testing showed MYD88 L265p and CXCR4 were both negative, postoperative pathology result of retroperitoneal lymph node biopsy was marginal zone lymphoma (mature small B type, prone to NMZL),and immunohistochemistry results: CD3, CD5, CD138, κ, λ, CD10, Cyclin D1 were negative, CD20, Pax-5, CD23 (FDC), bcl-2 were positive; Ki-67 positive index < 5%. The final diagnosis was NMZL with elevated monoclonal IgM. Partial remission was achieved after 8 cycles of reduced-dose CHOP regimen; thalidomide was used in the maintenance treatment, the disease condition was stable until August in 2021 and the follow-up was continuing.Conclusions:NMZL with elevated monoclonal IgM is relatively rare. Its diagnosis should be differentiated from Waldenstr?m macroglobulinemia and other inert B-cell lymphomas. Currently, there is no standard treatment and following the principle of individualized treatment can improve the prognosis of patients.
