The clinical characteristics of a neonatal patient with movement disorder and arthrogryposis (NDEEMA) caused by gain-of-function mutation of the SCN1A gene were reported in this article. The 1-year-and-9-month-old boy started seizures since 2 hours after birth. He had funnel-breast, dislocation of the hip, and bipedal varus. Genetic testing showed SCN1A gene de novo missense mutation c.706A>G(p.Ile236Val), causing overall gain-of-function effect. The frequency of seizures decreased significantly after treatment of oxcarbazepine.

Objective To analyze the differences of brain activity between first-episode untreated depressive patients with and without suicidal ideation(SI),and its correlations with clinical characteristics.Methods A total of 40 major depressive disorder(MDD)patients with SI(MDD+SI group),40 patients without SI MDD(MDD+NSI group),and 40 healthy controls(HC)(HC group)were enrolled.The 17-item Hamilton depression scale(HAMD-17)and Beck scale for suicide ideation(BSI)were used to assess the severity of depression and SI,respectively.MRI data were collected.The values of fractional amplitude of low-frequency fluctuation(fALFF)were calculated.Results(1)Compared with the HC group,the MDD+NSI group showed decreases in the fALFF val-ues of the default network and attention network.The fALFF values of the attention network in the MDD+SI group showed decreases.Compared with the MDD+NSI group,the MDD+SI group showed decreases in the fALFF values of the attention network.(2)The fALFF values in the left middle frontal gyrus were negatively correlated with the total score of HAMD-17(r=-0.55;P<0.001)in the MDD+NSI group,while the fALFF values in the left middle frontal gyrus were negatively correlated with the total score of HAMD-17(r=-0.53;P<0.001)and the total score of BSI(r=-0.51;P<0.001)in the MDD+SI group.(3)The optimal critical value of fALFF value in left middle frontal gyrus for predicting SI occurrence in MDD patients was-0.039,area under the curve(AUC)was 0.76,sensitivity was 0.63,and specificity was 0.80.Conclusion The decreased local activity intensity in the left middle frontal gyrus of the brain might be the central mechanism for the occurrence of SI in MDD patients.In addition,the left middle frontal gyrus might have certain value in identifying SI and predicting the severity of SI.

Objective To investigate the detection rate and related influencing factors of gastrointestinal diseases in grass-roots personnel.Methods A total of 481 grass-roots personnel were enrolled and examined by magnetic-controlled capsule endoscopy(MCCE).Multivariate logistic regression were used to analyze the influencing factors of gastrointestinal diseases detected by MCCE.Results All personnel completed MCCE,and gastrointestinal diseases were detected in 154(32.0%)cases,including 106 cases of erosive gastritis,25 cases of chronic atrophic gastritis,17 cases of digestive tract polyp,16 cases of gastric ulcer,5 cases of reflux esophagitis,4 cases of cardia,1 case of duodenitis,and 1 case of enteritis.Gastrointestinal diseases was correlated with special operation posts,long-term tasks within recent 6 months,abdominal distension,belching,nausea and vomiting,diarrhea and other symptoms(all P＜0.05).Multivariate logistic regression analysis showed that the risk factors of gastrointestinal diseases were working in special operation posts,performing long tasks within 6 months,belching,nausea and vomiting symptoms(all P＜0.05).Conclusion The overall detection rate of gastrointestinal diseases(mainly acid related diseases)is relatively high,and its incidence is closely related to working in special operation posts and performing long-term tasks within recent 6 months.Personnel working in special operation posts should be more alert to gastrointestinal diseases.Gastrointestinal symptoms have reference value for the prediction of lesions,but more attention should be paid to the identification of functional gastrointestinal diseases with endoscopy.

Objective To explore the value of deep learning image reconstruction(DLIR)algorithm to improve the quality of low keV monochromatic portal vein images of energy spectrum CT.Methods Fifty patients who underwent enhanced upper abdominal energy spectrum CT scan were selected.Mixed-model adaptive statistical iterative reconstruction-Veo(50%ASIR-V)algorithm and high-deep learning image reconstruction(DLIR-H)algorithm were used to obtain monochromatic images at 40-70 keV(with intervals of 10 keV).The CT and standard deviation(SD)values of the portal vein trunk,left and right branches,and erector spinae muscle were measured in the transverse position,and the signal-to-noise ratio(SNR)and portal vein contrast-to-noise ratio(CNR)were calculated for objective evaluation.The portal vein image quality between the two algorithms and different energy was subjectively scored by two physicians.Results In terms of objective evaluation:compared with 50%ASIR-V,the CNR and SNR of portal vein in monochromatic DLIR-H images at the same keV between 40-70 keV energy levels were increased while the SD value was decreased(P＜0.05),and the CT value was unchanged;there was no statistical difference in the magnitude of change in CNR between the two algorithms at different energy levels(P＞0.05);there was a statistically significant difference in the magnitude of change in SNR and SD value(P＜0.05)and the magnitude of change was the largest at 40 keV;comparison between different energy levels of DLIR-H,the CNR and SD value of 40 keV DLIR-H were the highest(P＜0.05),and there was no significant difference in the SNR(P＞0.05).In terms of subjective evaluation:there was no significant difference between the subjective scores of the two algorithms at the same keV from 40-70 keV(P＞0.05),and the two reconstruction algorithms at 40 keV and 50 keV had the highest subjective scores between different keV.Conclusion The DLIR algorithm can reduce the noise of low keV monochromatic images,improve the image quality of portal vein.

This study investigated the effects and underlying mechanisms of the luteolin-naringenin combination(LN)on liver injury induced by acetaminophen(APAP).Forty-eight Kunming mice were randomly allocated into six groups:a normal control group,an APAP-induced liver injury model group,a positive drug treatment group,and three LN treatment groups with low,medium,and high doses.After the final drug administration,the mice were fasted for 12 hours prior to eu-thanasia for sample collection.Serum transaminase activity,oxidative stress indices,and hematoxy-lin-eosin(HE)staining were assessed to evaluate the effects of LN on APAP-induced hepatic inju-ry.Additionally,Western blot analysis was conducted to examine the expression levels of sphingo-sine kinase 1(SPHK1)and endoplasmic reticulum stress(ERS)-related proteins,thereby elucida-ting the potential mechanisms by which LN mitigates APAP-induced liver injury.The results dem-onstrated that varying concentrations of LN effectively ameliorated serum aminotransferase activi-ty and oxidative stress levels induced by APAP in a dose-dependent manner.Histopathological ex-amination via HE staining revealed significant improvement in APAP-induced liver tissue injury following treatment with different concentrations of LN.Furthermore,Western blot analysis indi-cated that the protein expressions of SPHK1,CHOP,p-IRE1α,ATF6,p-PERK,p-eIF2α,and ATF4 were markedly reduced after administration of various concentrations of LN.The results demonstrate that LN exhibits a significant protective effect against APAP-induced liver injury by inhibiting the SPHK1-mediated aberrant expression of ERS-related molecules.This study high-lights the importance of targeting SPHK1 in the treatment of APAP liver injury and provides a no-vel therapeutic approach through the multi-target and multi-pathway combination of monomers.
