Objective:To explore the split-face phenomenon in patients with bulbar-involved amyotrophic lateral sclerosis (ALS) through clinical and electrophysiological studies.Methods:A total of 52 clinically definite and clinically probable cases of bulbar-involved ALS, diagnosed according to the World Federation of Neurology El Escorial criteria, were retrospectively collected in the Third Central Hospital of Tianjin from September 2019 to November 2022. And 58 patients with idiopathic facial nerve paralysis with onset time≤7 days who visited the Department of Neurology of the Third Central Hospital of Tianjin during the same period were collected as control group. The firm eye closure (FC) score and cheek bulge (CB) score were used to assess the clinical involvement of facial muscles (dividing into facial muscle involvement group and non-facial muscle involvement group) and the presence of the split-face phenomenon (strong eye closure and weak cheek bulging) in ALS patients. The compound muscle action potential (CMAP) amplitudes of the bilateral orbicularis oculi and orbicularis oris muscles were measured using the Nicolet EDX Viking electromyography/evoked potential system. The CMAP amplitude ratio was calculated. The facial nerve electrophysiological differences were compared between ALS patients with bulbar involvement and patients with idiopathic facial nerve paralysis. The analysis of electrophysiological data across various groups was carried out utilizing the Kruskal-Wallis H test, while pairwise comparisons between groups were executed employing the Bonferroni correction method. Additionally, a stepwise binary Logistic regression analysis was implemented to ascertain the factors associated with facial muscle involvement in patients with bulbar-involved ALS. The receiver operating characteristic (ROC) curve was used to assess the diagnostic accuracy of facial nerve electrophysiological testing in diagnosing ALS in the presence of symptoms of facial muscle involvement. Results:Among the 52 ALS patients with bulbar involvement, there were 20 cases (38.5%) with facial muscle involvements, all of which were bilateral; 16 patients (30.8%) exhibited weakness solely in the ability to puff their cheeks, 1 patient (1.9%) presented with weakness exclusively in closing the eyes, and 3 patients (5.8%) experienced weakness in both closing the eyes and puffing the cheeks. The Revised Amyotrophic Lateral Sclerosis Functional Rating Scale (ALSFRS-R) score of the facial muscle involvement group was lower compared to the non-facial muscle involvement group (36.90±9.20 vs 40.75±5.21, t=2.419, P=0.019), while the FC score and CB score were higher in the facial muscle involvement group [FC score: 0(0, 1) vs 0(0, 0), U=5.854, P<0.001; CB score: 4(3, 4) vs 0(0, 0), U=9.069, P<0.001], showing statistically significant differences. There was no statistically significant difference in the CMAP amplitude of the orbicularis oculi muscle between the facial muscle involvement group and the healthy side of the idiopathic facial nerve paralysis group, the affected side of the idiopathic facial nerve paralysis group, and the non-facial muscle involvement group (all P>0.05). The CMAP amplitude of the orbicularis oris muscle in the facial muscle involvement group [1 100.00 (775.00, 1 375.00) μV] was lower than that in the healthy side of the idiopathic facial nerve paralysis group [1 800.00 (1 400.00, 2 300.00) μV] and the non-facial muscle involvement group [1 555.00 (1 202.50, 1 980.00) μV], with statistically significant differences ( H=5.884, P<0.001; H=4.114, P<0.001). There was no statistically significant difference in the CMAP amplitude of the orbicularis oris muscle between the facial muscle involvement group and the affected side of the idiopathic facial nerve paralysis group ( P>0.05). The CMAP amplitude ratio of the orbicularis oculi/orbicularis oris muscles in the facial muscle involvement group [0.83(0.51, 1.14)] was higher than that in the healthy side of the idiopathic facial nerve paralysis group [0.55(0.39, 0.73)], the affected side of the idiopathic facial nerve paralysis group [0.57(0.40, 0.73)], and the non-facial muscle involvement group [0.60(0.42, 0.71)], with statistically significant differences ( H=-3.440, P=0.003; H=-3.433, P=0.004; H=-3.225, P=0.008). Logistic regression analysis revealed that the CMAP amplitude of orbicularis oris muscle ( OR=0.998,95% CI 0.997-0.999, P<0.001) and ALSFRS-R score ( OR=0.916,95% CI 0.857-0.979, P=0.010) were factors associated with facial muscle involvement in ALS patients with bulbar involvement. The ROC curve analysis results showed that the area under the curve (AUC) of the orbicularis oculi muscle CMAP was 0.629, the AUC of the orbicularis oris muscle CMAP was 0.838, and the AUC of the CMAP amplitude ratio of the orbicularis oculi/orbicularis oris muscles was 0.690 in the facial muscle involvement group. Conclusions:Patients with bulbar-involved ALS have split-face phenomenon characterized by strong eye closure and weak cheek bulging. When bulbar-involved ALS patients have symptoms of facial muscle involvement, the CMAP amplitude of the orbicularis oris muscle decreases significantly, whereas the CMAP amplitude of the orbicularis oculi muscle remains relatively stable, further illustrating the split phenomenon.

Objective:To analyze the clinical and electrophysiological characteristics of patients with sensory neuronopathies (SNN), and to evaluate the significance of electrophysiological markers in the diagnosis and assessment of disease progression.Methods:A retrospective analysis was performed to evaluate the clinical manifestations, electrophysiological characteristics, and spinal cord magnetic resonance imaging (MRI) features of 8 cases diagnosed with SNN at the Third Central Hospital of Tianjin between 2015 and 2023. The neurophysiological examination mainly included limb nerve conduction study (NCS), same core needle electrode electromyography, somatosensory evoked potential (SEP), skin sympathetic reflex (SSR), and contact heat evoked potential (CHEP).Results:Among the 8 cases with SNN, 7 cases exhibited asymmetrical onset and a non-length-dependent pattern. All the 8 cases presented with severe deep sensory ataxia, accompanied by superficial sensory abnormalities and tendon areflexia. Paraneoplastic SNN were the most prevalent etiological subtype (4 cases), all of whom presented peripheral neuropathy as the initial symptom. Among these 4 cases, malignancies were identified in 3 cases and 3 cases presented with anti-Hu antibodies. Among the remaining 4 patients, 2 cases were autoimmune and the other 2 cases were idiopathic. NCS results of the 8 cases revealed decrease or absence of sensory nerve action potential (SNAP) amplitudes, with normal sensory conduction velocities. Six cases showed abnormal SEP, including 2 cases of central damage and 4 cases of peripheral damage, 5 cases had abnormal SSR, and 2 cases exhibited abnormal CHEP. Motor nerve conduction studies were normal in all 8 cases. Six patients underwent spinal MRI, and 4 exhibited abnormal signals in dorsal columns.Conclusions:The hallmark clinical manifestation of SNN is sensory ataxia, characterized by substantial impairment of superficial sensation, typically manifesting in a non-length-dependent distribution. Beyond the widespread and significant reduction in SNAP amplitudes, SNN may also exhibit additional electrophysiological impairments, such as those observed in SEP, SSR and CHEP.SEP combined with spinal cord MRI can improve the detection rate for damages in the central sensory conduction pathway.

Objective:This study aims to analyze historical trends and predict future trends of disability-adjusted life years (DALYs) attributable to high BMI for osteoarthritis (OA) in China. OA is a common chronic degenerative joint disease, with high body mass index (BMI) being a significant risk factor. in China.Methods:Based on the Global Burden of Disease (GBD) 2021 database, we analyzed trends in high-BMI-attributable OA. The ASR of hogh-BMI-attributable OA DALYs increased from DALYs in China from 1990 to 2021. A Bayesian age-period-cohort (BAPC) model was used to predict trends from 2022 to 2046. Age-standardized rates (ASR) and estimated annual percentage changes (EAPC) were calculated to assess trend changes of trends. A Bayesian age-period-cohort (BAPC) model was used to predict trends from 2022 to 2046. Chi-square tests were used to compare differences in high BMI attribution proportions between regions and years.Results:From 1990 to 2021, China′s OA DALYs increased from 1.829 to 5.327 million, with the proportion attributable to high BMI rising from 13.47% to 21.86% ( χ2=60 527.25, P<0.001). The ASR of high-BMI-attributable to OA increased from 27.4 (-2.2, 81.5) per 100,000 to 53.0 (-4.7, 150.7) per 100 000, with an EAPC of 2.48% [95% (uncertainty interval, UI): 2.35, 2.62]. In 2021, females showed significantly higher ASR (69.2 per 100 000) than males (36.1 per 100 000). Knee OA (ASR: 50.5/100 000) demonstrated substantially higher burden than hip OA (ASR: 2.5/100 000). Age effect analysis showed DALYs peaked at ages 80~90; period effect indicated accelerated growth after 2005; cohort effect showed a U-shaped trend with the 1990 birth cohort having the highest relative risk (approximately 3.0). Projections indicated that up to 2046, total OA DALYs will reach approximately 2.39 million with an ASR of about 71, showing more significant growth among females (ASR reaching 100). Conclusion:High-BMI-attributable to OA DALYs in China shows a significant upward trend, and is expected to continue. This trend is more pronounced among females and elderly populations than males, highlighting the urgency of implementing preventive measures for high-risk groups, particularly in weight management.

In recent years,the market share of food and medicine homology substances has continued to grow,and various types of contamination issues have become the focus of attention both inside and outside the industry.The contamination not only affects the original medicinal quality,but also leads to the accumulation of toxic substances in the human body,causing acute and chronic severe hazards such as vomiting,poisoning and cancer.Therefore,the development of biosensors that can conveniently,accurately and sensitively detect various pollutants in food and medicine homology substances has become a research hotspot.Aptasensors based on metal-organic frameworks(MOFs)with advantages such as strong specificity,rapid response and simple operation,have been widely used in detection of various pollutants.This review focused on the research progress of aptasensors based on MOFs for detection of food and medicine homology contamination in the past few years,and provided a detailed comparison and analysis for detection of chemical pollutants(such as pesticide residues,heavy metal residues,mycotoxins,etc.)and microbial contamination in food and medicine homology substances.Besides,the development trend and possible challenges of MOFs aptasensors in detection of food and medicine homology substances in the future were discussed,which was anticipated to provide a reference for the development of new MOFs aptasensors.

This study aims to explore the effects of Buzhong Yiqi Decoction(BYD) on the cyclic guanosine monophosphate-adenosine monophosphate synthase(cGAS)-stimulator of interferon genes(STING) signaling pathway in the mouse model of autoimmune thyroiditis(AIT) and the mechanism of BYD in alleviating the immune injury. Forty-eight NOD.H-2~(h4) mice were assigned into normal, model, low-, medium-, and high-dose BYD, and selenium yeast tablets groups(n=8). Mice of 8 weeks old were treated with 0.05% sodium iodide solution for 8 weeks for the modeling of AIT and then administrated with corresponding drugs by gavage for 8 weeks before sampling. High performance liquid chromatography was employed to measure the astragaloside Ⅳ content in BYD. Hematoxylin-eosin staining was employed to observe the pathological changes in the mouse thyroid tissue. Enzyme-linked immunosorbent assay was employed to measure the serum levels of thyroid peroxidase antibody(TPO-Ab), thyroglobulin antibody(TgAb), and interferon-γ(IFN-γ). Flow cytometry was employed to detect the distribution of T cell subsets in the spleen. The immunohistochemical method was used to detect the expression of cGAS, STING, TANK-binding kinase 1(TBK1), and interferon regulatory factor 3(IRF3). Real-time PCR and Western blot were employed to determine the mRNA and protein levels, respectively, of markers related to the cGAS-STING signaling pathway in the thyroid tissue. The results showed that the content of astragaloside Ⅳ in BYD was(7.06±0.08) mg·mL~(-1). Compared with the normal group, the model group showed disrupted structures of thyroid follicular epithelial cells, massive infiltration of lymphocytes, and elevated levels of TgAb and TPO-Ab. Compared with the model group, the four treatment groups showed intact epithelial cells, reduced lymphocyte infiltration, and lowered levels of TgAb and TPO-Ab. Compared with the normal group, the model group showed increases in the proportions of Th1 and Th17 cells, a decrease in the proportion of Th2 cells, and an increase in the IFN-γ level. Compared with the model group, the four treatment groups presented decreased proportions of Th1 and Th17 cells and lowered levels of IFN-γ, and the medium-dose BYD group showed an increase in the proportion of Th2 cells. Compared with the normal group, the modeling up-regulated the mRNA levels of cGAS, STING, TBK1, and IRF3 and the protein levels of cGAS, p-STING, p-TBK1, and p-IRF3. Compared with the model group, the four treatment groups showed reduced levels of cGAS, STING, TBK1, and IRF3-positive products, down-regulated mRNA levels of cGAS, STING, and TBK1, and down-regulated protein levels of cGAS and p-STING. The high-dose BYD group showed down-regulations in the mRNA level of IRF3 and the protein levels of p-TBK1 and p-IRF3. The above results indicate that BYD can repair the imbalance of T cell subsets, alleviate immune injury, and reduce thyroid lymphocyte infiltration in AIT mice by inhibiting the cGAS-STING signaling pathway.

Objective To investigate the effect of LINC00839 on the malignant biological behavior of endometrial cancer cells by regulating the miR-625-5p/cytoplasmic polyadenylation element binding protein 4 (CPEB4) axis. Methods The cancer tissues and adjacent tissues of 46 patients with endometrial cancer were obtained,endometrial cancer cells of HEC-1B,Ishikawa and RL95-2 and human endometrial epithelial cells (HEEC) were cultured in vitro,and the expression levels of LINC00839,miR-625-5p and CPEB4 in tissues and cells were detected. HEC-1B cells were divided into the HEC-1B group (conventional culture),sh-Ctrl group (transfected with sh-Ctrl),sh-LINC00839 group (transfected with shRNA-LINC00839),anti-miR-625-5p group (transfected with shRNA-LINC00839 and miR-625-5p inhibitor),and anti-NC group (transfected with shRNA-LINC00839 and inhibitor-NC). The proliferation,apoptosis,migration and invasion abilities of HEC-1B cells in each group were compared,and the expressions of CPEB4 and epithelial-mesenchymal transition (EMT) related proteins were determined. The targeting relationships between LINC00839 and miR-625-5p,and miR-625-5p and CPEB4 were analyzed. Results The mRNA expression of LINC00839 and CPEB4,as well as the positive expression rate of CPEB4 protein in endometrial cancer tissues were higher than those in adjacent tissues,and the expression of miR-625-5p was lower than that in adjacent tissues (P<0.05). Compared with HEEC cells,the expression of LINC00839 and the mRNA and protein expression of CPEB4 in Ishikawa,RL95-2 and HEC-1B cells increased (P<0.05),and the expression of miR-625-5p decreased (P<0.05). Compared with the sh-LINC00839 group and anti-NC group,the protein expression of N-cadherin,Vimentin,and CPEB4,24-hour absorbance,and migration and invasion cell numbers of HEC-1B cells in the HEC-1B group,sh-Ctrl group and anti-miR-625-5p group increased (P<0.05),while the expression of E-cadherin protein and cell apoptosis rate decreased (P<0.05). There were binding sites between LINC00839 and miR-625-5p,miR-625-5p and CPEB4,with targeting regulatory relationships. Conclusion LINC00839 is related to the malignant biological behavior of endometrial cancer cells,interference with LINC00839 expression can inhibit the proliferation,invasion and migration,and promote apoptosis of HEC-1B cells,and its mechanism may be achieved by regulating the miR-625-5p/CPEB4 axis.

Objective:To explore the split-face phenomenon in patients with bulbar-involved amyotrophic lateral sclerosis (ALS) through clinical and electrophysiological studies.Methods:A total of 52 clinically definite and clinically probable cases of bulbar-involved ALS, diagnosed according to the World Federation of Neurology El Escorial criteria, were retrospectively collected in the Third Central Hospital of Tianjin from September 2019 to November 2022. And 58 patients with idiopathic facial nerve paralysis with onset time≤7 days who visited the Department of Neurology of the Third Central Hospital of Tianjin during the same period were collected as control group. The firm eye closure (FC) score and cheek bulge (CB) score were used to assess the clinical involvement of facial muscles (dividing into facial muscle involvement group and non-facial muscle involvement group) and the presence of the split-face phenomenon (strong eye closure and weak cheek bulging) in ALS patients. The compound muscle action potential (CMAP) amplitudes of the bilateral orbicularis oculi and orbicularis oris muscles were measured using the Nicolet EDX Viking electromyography/evoked potential system. The CMAP amplitude ratio was calculated. The facial nerve electrophysiological differences were compared between ALS patients with bulbar involvement and patients with idiopathic facial nerve paralysis. The analysis of electrophysiological data across various groups was carried out utilizing the Kruskal-Wallis H test, while pairwise comparisons between groups were executed employing the Bonferroni correction method. Additionally, a stepwise binary Logistic regression analysis was implemented to ascertain the factors associated with facial muscle involvement in patients with bulbar-involved ALS. The receiver operating characteristic (ROC) curve was used to assess the diagnostic accuracy of facial nerve electrophysiological testing in diagnosing ALS in the presence of symptoms of facial muscle involvement. Results:Among the 52 ALS patients with bulbar involvement, there were 20 cases (38.5%) with facial muscle involvements, all of which were bilateral; 16 patients (30.8%) exhibited weakness solely in the ability to puff their cheeks, 1 patient (1.9%) presented with weakness exclusively in closing the eyes, and 3 patients (5.8%) experienced weakness in both closing the eyes and puffing the cheeks. The Revised Amyotrophic Lateral Sclerosis Functional Rating Scale (ALSFRS-R) score of the facial muscle involvement group was lower compared to the non-facial muscle involvement group (36.90±9.20 vs 40.75±5.21, t=2.419, P=0.019), while the FC score and CB score were higher in the facial muscle involvement group [FC score: 0(0, 1) vs 0(0, 0), U=5.854, P<0.001; CB score: 4(3, 4) vs 0(0, 0), U=9.069, P<0.001], showing statistically significant differences. There was no statistically significant difference in the CMAP amplitude of the orbicularis oculi muscle between the facial muscle involvement group and the healthy side of the idiopathic facial nerve paralysis group, the affected side of the idiopathic facial nerve paralysis group, and the non-facial muscle involvement group (all P>0.05). The CMAP amplitude of the orbicularis oris muscle in the facial muscle involvement group [1 100.00 (775.00, 1 375.00) μV] was lower than that in the healthy side of the idiopathic facial nerve paralysis group [1 800.00 (1 400.00, 2 300.00) μV] and the non-facial muscle involvement group [1 555.00 (1 202.50, 1 980.00) μV], with statistically significant differences ( H=5.884, P<0.001; H=4.114, P<0.001). There was no statistically significant difference in the CMAP amplitude of the orbicularis oris muscle between the facial muscle involvement group and the affected side of the idiopathic facial nerve paralysis group ( P>0.05). The CMAP amplitude ratio of the orbicularis oculi/orbicularis oris muscles in the facial muscle involvement group [0.83(0.51, 1.14)] was higher than that in the healthy side of the idiopathic facial nerve paralysis group [0.55(0.39, 0.73)], the affected side of the idiopathic facial nerve paralysis group [0.57(0.40, 0.73)], and the non-facial muscle involvement group [0.60(0.42, 0.71)], with statistically significant differences ( H=-3.440, P=0.003; H=-3.433, P=0.004; H=-3.225, P=0.008). Logistic regression analysis revealed that the CMAP amplitude of orbicularis oris muscle ( OR=0.998,95% CI 0.997-0.999, P<0.001) and ALSFRS-R score ( OR=0.916,95% CI 0.857-0.979, P=0.010) were factors associated with facial muscle involvement in ALS patients with bulbar involvement. The ROC curve analysis results showed that the area under the curve (AUC) of the orbicularis oculi muscle CMAP was 0.629, the AUC of the orbicularis oris muscle CMAP was 0.838, and the AUC of the CMAP amplitude ratio of the orbicularis oculi/orbicularis oris muscles was 0.690 in the facial muscle involvement group. Conclusions:Patients with bulbar-involved ALS have split-face phenomenon characterized by strong eye closure and weak cheek bulging. When bulbar-involved ALS patients have symptoms of facial muscle involvement, the CMAP amplitude of the orbicularis oris muscle decreases significantly, whereas the CMAP amplitude of the orbicularis oculi muscle remains relatively stable, further illustrating the split phenomenon.

Objective:To analyze the clinical and electrophysiological characteristics of patients with sensory neuronopathies (SNN), and to evaluate the significance of electrophysiological markers in the diagnosis and assessment of disease progression.Methods:A retrospective analysis was performed to evaluate the clinical manifestations, electrophysiological characteristics, and spinal cord magnetic resonance imaging (MRI) features of 8 cases diagnosed with SNN at the Third Central Hospital of Tianjin between 2015 and 2023. The neurophysiological examination mainly included limb nerve conduction study (NCS), same core needle electrode electromyography, somatosensory evoked potential (SEP), skin sympathetic reflex (SSR), and contact heat evoked potential (CHEP).Results:Among the 8 cases with SNN, 7 cases exhibited asymmetrical onset and a non-length-dependent pattern. All the 8 cases presented with severe deep sensory ataxia, accompanied by superficial sensory abnormalities and tendon areflexia. Paraneoplastic SNN were the most prevalent etiological subtype (4 cases), all of whom presented peripheral neuropathy as the initial symptom. Among these 4 cases, malignancies were identified in 3 cases and 3 cases presented with anti-Hu antibodies. Among the remaining 4 patients, 2 cases were autoimmune and the other 2 cases were idiopathic. NCS results of the 8 cases revealed decrease or absence of sensory nerve action potential (SNAP) amplitudes, with normal sensory conduction velocities. Six cases showed abnormal SEP, including 2 cases of central damage and 4 cases of peripheral damage, 5 cases had abnormal SSR, and 2 cases exhibited abnormal CHEP. Motor nerve conduction studies were normal in all 8 cases. Six patients underwent spinal MRI, and 4 exhibited abnormal signals in dorsal columns.Conclusions:The hallmark clinical manifestation of SNN is sensory ataxia, characterized by substantial impairment of superficial sensation, typically manifesting in a non-length-dependent distribution. Beyond the widespread and significant reduction in SNAP amplitudes, SNN may also exhibit additional electrophysiological impairments, such as those observed in SEP, SSR and CHEP.SEP combined with spinal cord MRI can improve the detection rate for damages in the central sensory conduction pathway.
