Objective:To explore the mediating role of rumination thinking between demoralization and quality of life in malignant tumor patients, provide guidance and reference for helping tumor patients overcome rumination thinking and demoralization and improve quality of life.Methods:From February 2020 to June 2022, 189 patients with malignant tumors admitted to the Department of Oncology of the First Affiliated Hospital of Guangxi Medical University were selected by convenience sampling method as the research objects, and a cross-sectional survey was conducted using general information questionnaire, Demoralization Scale-Mandarin Version, Ruminative Responses Scale, Punctional Assessment of Cancer Therapy-General.Results:Among 189 malignant tumor patients, there were 102 males, 87 females, aged (43.54 ± 13.12) years old. The total score of loss of demoralization was (34.37 ± 10.34) points, the total score of rumination thinking was (41.01 ± 17.10) points, the total score of quality of life was (48.51 ± 15.41) points. The Pearson analysis results showed that the total score of demoralization in malignant tumor patients was negatively correlated with the total score of quality of life ( r = -0.502, P<0.01); the total score of rumination thinking was negatively correlated with the total score of quality of life ( r = -0.465, P<0.01), and the total score of demoralization was positively correlated with the total score of rumination thinking ( r = 0.628, P<0.01). Bootstrap mediation test results showed that ruminant thinking played a partial mediating effect between demoralization and quality of life of patients with malignant tumors, accounted for 30.9% of the total effect. Conclusions:Rumination plays a partially mediating role in the demoralization and quality of life of patients with malignant tumors, suggesting that clinical staff can improve the quality of life of patients with tumors by developing a systematic and comprehensive cognitive-behavioral intervention strategy to improve the demoralization and rumination.

The 2023 China Health Report on Spine Degeneration noted a significant increase in lumbar surgery among patients under 35 years old in recent years, indicating a trend towards younger onset of cervical and lumbar diseases. Lumbar intervertebral disc herniation has become a major concern, making the study of disc degeneration pathogenesis and treatment methods clinically significant. At present, human intervertebral disc diseases are primarily diagnosed through imaging due to the challenges of obtaining tissue samples from the spine. Therefore, experimental animals have emerged as alternative research subjects because they are cost-effective, have short experimental cycles, and are easily accessible. Given the structural and physiological differences between human and other animal intervertebral discs, comparing their anatomy and histological characteristics forms the foundation of research into human disc degeneration. The purpose of this paper is to collect and review relevant studies on anatomical and histological structures of intervertebral discs in different animals and conduct a comparative analysis from four aspects, namely, intervertebral disc height, lumbar disc geometry, lumbar disc cartilaginous endplate characteristics, and extracellular matrix components. The results show that humans, kangaroos, sheep, pigs, and rats exhibit similar relative heights between the sixth and seventh cervical vertebrae. Mice possess lumbar disc geometries most akin to humans. Compared to other animals, humans have the thickest cartilaginous endplates and the lowest cell densities. The collagen within the fibrous annulus differs most notably in pigs compared to humans, while water content in the nucleus pulposus is consistent across pigs, sheep, rabbits, rats, and humans. Additionally, this paper describes the commonalities and discrepancies in disc degeneration manifestations between humans and animals, and summarizes modeling methods for disc degeneration in different experimental animals. Ultimately, the aims of this paper is to provide fundamental data for selecting suitable experimental animal models for the study of intervertebral disc degeneration.

Diabetic nephropathy (DN) is a clinical syndrome characterized by persistent proteinuria and progressive decline in renal function, and is one of the microvascular complications of diabetes. With the in-depth understanding of the pathogenesis of DN, the role of intestinal flora imbalance in the disease has been found clinically. This suggests that restoring the host′s healthy gut flora may be a means of improving DN. In fact, recent studies have shown that many of the drugs currently used to treat DN affect gut microbiota composition. In this review, intestinal flora is regarded as one of the main factors affecting the development of DN, and DN therapy targeting intestinal flora is summarized to provide new ideas for the diagnosis and treatment of DN.

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.

Abstract: Objective To compare the differences in the expression of interleukin-8 (IL-8) and signal transducer and activator of transcription 3 (STAT3) among three groups of individuals: patients with multi-drug resistant tuberculosis (MDR-TB), patients with drug-susceptible tuberculosis (DSP-TB), and healthy controls. By analyzing the differences between these groups, the study seeks to provide a reference basis for clinical auxiliary diagnosis of new type tuberculosis. Methods The differences in mRNA expression profiles of chip from peripheral blood mononuclear cells (PBMCs) among three groups were analyzed. MDR-TB and DSP-TB patients were selected as study subjects, with healthy individuals serving as a control group, and the serum IL-8 concentration of each group was measured using an ELISA assay to compare differences between groups. Additionally, PBMCs from all groups were isolated and total RNA was extracted for analysis of IL-8 and STAT3 mRNA expression using quantitative real-time PCR(Q-PCR). Differences in STAT3 protein expression among the groups were also compared by Western blot assay. Results The serum IL-8 concentration in the MDR-TB and DSP-TB groups was significantly higher than that in the healthy control group, with a statistically significant difference (P<0.05). The relative expression level of IL-8 mRNA in PBMCs of the MDR-TB group and DSP-TB group was also significantly higher than that of the healthy control group, with a statistical significance (P<0.05). Both Q-PCR and Western Blot results revealed that the expression of STAT3 in the healthy, DSP-TB and MDR-TB groups sequentially increased, presenting statistically significant differences between the groups (P<0.05), consistent with the mRNA chip results. Conclusions The expression of IL-8 in active tuberculosis patients (ATB) is significantly increased, which can be used as a marker to distinguish ATB from healthy populations. The changes of STAT3 concentration not only serve as a reference for the diagnosis of ATB but can also distinguish between DSP-TB and MDR-TB populations. The combined detection of IL-8 and STAT3 holds promise as a clinical auxiliary diagnostic basis for different tuberculosis patients.

Background: Peste des petits ruminants (PPR), caused by the PPR virus (PPRV), is an acute and fatal contagious disease that mainly infects goats, sheep, and other artiodactyls.Peripheral blood mononuclear cells (PBMCs) are considered the primary innate immune cells. Objectives: PBMCs derived from goats were infected with PPRV and analyzed to detect the relationship between PPRV replication and apoptosis or the inflammatory response. Methods: Quantitative real-time polymerase chain reaction was used to identify PPRV replication and cytokines expression. Flow cytometry was conducted to detect apoptosis and the differentiation of CD4+ and CD8+T cells after PPRV infection. Results: PPRV stimulated the differentiation of CD4+ and CD8+ T cells. In addition, PPRV induced apoptosis in goat PBMCs. Furthermore, apoptosis and the inflammatory response induced by PPRV could be suppressed by Z-VAD-FMK and Z-YVAD-FMK, respectively.Moreover, the virus titer of PPRV was attenuated by inhibiting caspase-1-dependent apoptosis and inflammation. Conclusions This study showed that apoptosis and the inflammatory response play an essential role in PPR viral replication in vitro, providing a new mechanism related to the cell host response.
