Functional dyspepsia (FD), characterized by persistent or recurrent dyspeptic symptoms without identifiable organic, systemic or metabolic causes, is an increasingly recognized global health issue. The objective of this guideline is to equip clinicians and nursing professionals with evidence-based strategies for the management and treatment of adult patients with FD using traditional Chinese medicine (TCM). The Guideline Development Group consulted existing TCM consensus documents on FD and convened a panel of 35 clinicians to generate initial clinical queries. To address these queries, a systematic literature search was conducted across PubMed, EMBASE, the Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP Database, China Biology Medicine (SinoMed) Database, Wanfang Database, Traditional Medicine Research Data Expanded (TMRDE), and the Traditional Chinese Medical Literature Analysis and Retrieval System (TCMLARS). The evidence from the literature was critically appraised using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. The strength of the recommendations was ascertained through a consensus-building process involving TCM and allopathic medicine experts, methodologists, pharmacologists, nursing specialists, and health economists, leveraging their collective expertise and empirical knowledge. The guideline comprises a total of 43 evidence-informed recommendations that span a range of clinical aspects, including the pathogenesis according to TCM, diagnostic approaches, therapeutic interventions, efficacy assessments, and prognostic considerations.

Objective:To investigate the epileptogenic networks of bilateral asymmetric tonic seizures (BATS) originating from the posterior insula using stereo-electroencephalography (SEEG).Methods:A retrospective analysis was performed. Among the epilepsy patients who underwent preoperative assessment and SEEG monitoring in the Epilepsy Department of Guangdong Sanjiu Brain Hospital from January 1, 2015 to July 1, 2024, 7 patients with insular epilepsy characterized by BATS originating from the posterior insula were selected based on anatomo-electro-clinical characteristics. The clinical characteristics, neuroimaging features, scalp EEG patterns, and SEEG recordings of the 7 patients were collected and analyzed. Via synchronously analyzing ictal semiology and electroanatomical propagation pathways shown by SEEG, the features of epileptogenic networks were elucidated. Results:Four patients had seizure onset from the dorsal-superior part of the left posterior insula, and 3 patients from the dorsal-superior part of the right posterior insula. The electroencephalographic characteristics of the seizure onset zones showed high consistency in these 7 patients: rhythmic spike or multiple spike discharges at the initial stage, and a low-amplitude rapid rhythm pattern subsequently. Totally, 3-10 seizures were recorded in each patient. Four patients experienced prodromal symptoms, including 3 patients with somatosensory symptoms (1 with chest and abdominal pain, 1 with contralateral facial numbness combined with throat constriction sensation, and 1 with contralateral limb numbness), and 1 patient with non-specific presentation (hugging family member before seizure). The seizure semiological evolution sequence was from prodrome to BATS, and then to secondary symptoms, with 3 patients exhibiting clustered spasms as secondary symptoms, and 4 patients showing eyelids and contralateral upper limb distal tonic-clonic manifestations as secondary symptoms. The epileptogenic networks followed a consistent pattern: the dorsal-superior part of the posterior insula leads to the middle-posterior part of the superior circular sulcus, to the ventral posterior insular and posterior circular sulcus, and then to the supplementary sensorimotor area (SSMA), and finally to the central sulcus, central region-vertex, and inferior parietal lobule. Only 2 patients had the anterior insular-involved epileptic brain networks, while the remaining 5 patients did not involve the anterior insular. During BATS, SEEG electrode contacts corresponding to the posterior insular, superior circular sulcus and SSMA exhibited low-amplitude rapid rhythm patterns.Conclusion:The seizures spread from the dorsal-superior part of the posterior insula to the middle-posterior part of the superior circular sulcus at the early stage of onset, and then connected with SSMA; these structures formed a epileptogenic brain network through abnormal synchronous discharge, which eventually led to BATS.

Objective:To summarize the clinical characteristics of elderly patients with stage Ⅰ diffuse large B-cell lymphoma (DLBCL) and analyze the factors associated with prognosis.Methods:A case series study was conducted by retrospectively collecting clinical data from patients aged over 60 years with newly diagnosed stage Ⅰ DLBCL across 20 medical centers in Jiangsu Province, China, between June 2010 and April 2023. The involved site, classification and treatment plan were summarized. The primary endpoints were progression-free survival (PFS) and overall survival (OS). Statistical analyses were performed using the Kaplan-Meier method, and Cox regression model.Results:The study included 255 patients with a median age of 69 years, of whom 130 (51.0%) were male, 66 (25.9%) were aged ≥75 years and 26 (10.1%) had a high Charlson Comorbidity Index (CCI) score of ≥2. Extranodal involvement was observed in 163 (63.9%) patients, with the stomach (37.4%, 61/163), intestine (19.0%, 31/163), testes (11.0%, 18/163), and breast (7.4%, 12/163) being the most frequently affected sites. The non-germinal center B-cell (non-GCB) subtype was prevalent in 63.7% of patients (142/223), with no significant difference between the nodal and extranodal groups ( P=0.681). Furthermore, 73.9% (184/249) and 11.7% (29/249) of patients received the R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone) and R-miniCHOP regimen, respectively. The overall 3-year PFS rate was 81.5%, and the 3-year OS rate was 85.6%. Patients aged ≥75 years ( HR=2.910, 95% CI 1.565-5.408, P=0.001) and/or with a CCI score ≥2 ( HR=2.324, 95% CI 1.141-4.732, P=0.020) had a significantly poorer PFS. Incorporating age ≥75 years and CCI score ≥2 into the stage-modified international prognostic index (sm-IPI) can better stratify the prognosis of elderly patients with stage Ⅰ DLBCL. The 3-year PFS rate was 48.7% in the high-risk group versus 85.7% in the low-risk group ( P<0.001). Conclusions:Our findings show that the elderly patients with stage Ⅰ DLBCL were predominantly characterized by extranodal involvement (particularly in the stomach and intestinal tract) and non-GCB subtype. Age ≥75 years and CCI ≥2 were identified as independent prognostic factors. The newly established sm-IPI-75-CCI incorporating these factors demonstrated superior prognostic discrimination compared to conventional risk assessment systems.

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.
