Efficacy of Mind-Regulating and Depression-Reliving Acupuncture in combination with Radiofrequency Thermocoagulation of Dorsal Root Ganglion for Post-herpetic Neuralgia.

PURPOSE: This study is aimed at evaluating the efficacy of Mind-Regulating and Depression-Relieving Acupuncture in combination with radiofrequency thermocoagulation of DRG for PHN. METHODS: PHN patients who presented to the Pain Department of Affiliated Hospital of Jiaxing University from November 2021 to June 2023 were included. The participants were assigned into two groups using a random number table: Acupuncture + RFTC (Group H, n = 44) group and RFTC (Group C, n = 44) group. The pain numerical rating score (NRS), visual analogue scale scores (VAS), IL-6 , Gal-3, oral dose of tramadol and gabapentin capsules levels were recorded before and after 1, 2, 4, 8 and 12 w of the treatment. RESULTS: After treatment, NRS scores in both groups were significantly lower than pretreatment scores at each time point. Compared with before treatment, the VAS scores at all time points after treatment was increased in both groups. Compared with before treatment, the doses of oral gabapentin capsules and tramadol were reduced in both groups after treatment. Compared with group C, the doses of oral gabapentin capsules and tramadol after the end of the treatment course were significantly reduced in group H. Compared with before treatment, the blood levels of Gal-3 and IL-6 were reduced at all points after treatment in both groups. Compared with group C, the blood Gal-3 and IL-6 levels were significantly reduced in group H. CONCLUSION: Compared with RFTC alone, acupuncture combined with RFTC of DRG has a better therapeutic effect for PHN.

Advances in the Treatment of Neuropathic Pain by Sympathetic Regulation.

PURPOSE OF REVIEW: To explore the mechanism and therapeutic effect of sympathetic nerve regulation on neuropathic pain. RECENT FINDINGS: A comprehensive search was conducted in the PubMed and CNKI libraries, using the following keywords: stele ganglion block, neuropathic pain, sympathetic nerve block, sympathetic chemical destruction, and sympathetic radiofrequency thermocoagulation. We selected and critically reviewed research articles published in English that were related to sympathetic modulation in the treatment of neuropathic pain. The collected literature will be classified according to content and reviewed in combination with experimental results and clinical cases. Neuropathic pain was effectively treated with sympathetic regulation technology. Its mechanism includes the inhibition of sympathetic nerve activity, regulation of the inflammatory response, and inhibition of pain transmission, which greatly alleviates neuropathic pain in patients. Stellate ganglion blocks, thoracic and lumbar sympathectomies, chemical destruction, and radiofrequency thermocoagulation have been widely used to treat neuropathic pain. Sympathetic regulation can effectively relieve pain symptoms and improve the patient's quality of life by inhibiting sympathetic nerve activity, reducing the production and release of pain-related mediators, and inhibiting pain transmission. CT-guided radiofrequency thermocoagulation of the thoracic and lumbar sympathetic nerves is effective and durable, with few complications, and is recommended as a treatment for intractable neuropathic pain.

CircNSD1 promotes cardiac fibrosis through targeting the miR-429-3p/SULF1/Wnt/ß-catenin signaling pathway.

Cardiac fibrosis is a detrimental pathological process, which constitutes the key factor for adverse cardiac structural remodeling leading to heart failure and other critical conditions. Circular RNAs (circRNAs) have emerged as important regulators of various cardiovascular diseases. It is known that several circRNAs regulate gene expression and pathological processes by binding miRNAs. In this study we investigated whether a novel circRNA, named circNSD1, and miR-429-3p formed an axis that controls cardiac fibrosis. We established a mouse model of myocardial infarction (MI) for in vivo studies and a cellular model of cardiac fibrogenesis in primary cultured mouse cardiac fibroblasts treated with TGF-ß1. We showed that miR-429-3p was markedly downregulated in the cardiac fibrosis models. Through gain- and loss-of-function studies we confirmed miR-429-3p as a negative regulator of cardiac fibrosis. In searching for the upstream regulator of miR-429-3p, we identified circNSD1 that we subsequently demonstrated as an endogenous sponge of miR-429-3p. In MI mice, knockdown of circNSD1 alleviated cardiac fibrosis. Moreover, silence of human circNSD1 suppressed the proliferation and collagen production in human cardiac fibroblasts in vitro. We revealed that circNSD1 directly bound miR-429-3p, thereby upregulating SULF1 expression and activating the Wnt/ß-catenin pathway. Collectively, circNSD1 may be a novel target for the treatment of cardiac fibrosis and associated cardiac disease.

Identification of hyperthermophilic D-allulose 3-epimerase from Thermotoga sp. and its application as a high-performance biocatalyst for D-allulose synthesis.

D-Allulose 3-epimerase (DAE) is a vital biocatalyst for the industrial synthesis of D-allulose, an ultra-low calorie rare sugar. However, limited thermostability of DAEs hinders their use at high-temperature production. In this research, hyperthermophilic TI-DAE (Tm = 98.4 ± 0.7 ℃) from Thermotoga sp. was identified via in silico screening. A comparative study of the structure and function of site-directed saturation mutagenesis mutants pinpointed the residue I100 as pivotal in maintaining the high-temperature activity and thermostability of TI-DAE. Employing TI-DAE as a biocatalyst, D-allulose was produced from D-fructose with a conversion rate of 32.5%. Moreover, TI-DAE demonstrated excellent catalytic synergy with glucose isomerase CAGI, enabling the one-step conversion of D-glucose to D-allulose with a conversion rate of 21.6%. This study offers a promising resource for the enzyme engineering of DAEs and a high-performance biocatalyst for industrial D-allulose production.

Sleep and internalizing problems in primary school children with attention-deficit hyperactivity disorder.

BACKGROUND: Internalizing and externalizing problems have received great attention, and children with ADHD exhibit high rates of comorbid internalizing and externalizing disorders. This study aimed to explore the relationship between sleep and internalizing problems in children with attention-deficit hyperactivity disorder (ADHD) and the probable mediating role of externalizing problems. METHODS: A total of 203 primary school children diagnosed with ADHD for the first time were recruited for this study. Children with ADHD were evaluated by Children's Sleep Habits Questionnaire (CSHQ), Strengths and Difficulties Questionnaire (SDQ). Internalizing problems were represented by emotional symptoms and peer problems of SDQ, and externalizing problems were represented by conduct problems and hyperactivity-inattention problems of SDQ. Multi-step linear regression analysis was used to investigate the mediating effect of externalizing problems on the relationship between sleep and internalizing problems. RESULTS: Sleep in children with ADHD was associated with emotional problems in internalizing problems, and conduct problems in externalizing problems mediated the association between sleep and emotional problems. CONCLUSION: For children with ADHD, when it is difficult to identify internalizing problems, especially emotional problems, we can take sleep and externalizing problems as clues to improve our clinical ability to recognize and deal with emotional problems. IMPACT: 1. We first explored the possible mediating role of conduct problems between sleep and emotional problems in primary school children with ADHD. 2. When it is difficult to identify internalizing problems, especially emotional problems, we can take sleep and externalizing problems as clues to improve our clinical ability to recognize emotional problems for children with ADHD. 3. For children with ADHD with potential internalizing problems, especially emotional problems, interventions for their sleep and externalizing problems may be the possible methods to deal with.

Altered intra- and inter-network brain functional connectivity associated with prolonged screen time in pre-school children with autism spectrum disorder.

Prolonged screen time (ST) has adverse effects on autistic characteristics and language development. However, the mechanisms underlying the effects of prolonged ST on the neurodevelopment of children with autism spectrum disorder (ASD) remain unclear. Neuroimaging technology may help to further explain the role of prolonged ST in individuals with ASD. This study included 164 cases, all cases were divided into low-dose ST exposure (LDE group 108 cases) and high-dose ST exposure (HDE group 56 cases) based on the average ST of all subjects. Spatial independent component analysis (ICA) was used to identify resting state networks (RSNs) and investigate intra- and inter-network alterations in ASD children with prolonged ST. We found that the total Childhood Autism Rating Scale (CARS) scores in the HDE group were significantly higher than those in the LDE group (36.2 ± 3.1 vs. 34.6 ± 3.9, p = 0.008). In addition, the developmental quotient (DQ) of hearing and language in the HDE group were significantly lower than those in the LDE group (31.5 ± 13.1 vs. 42.5 ± 18.5, p < 0.001). A total of 13 independent components (ICs) were identified. Between-group comparison revealed that the HDE group exhibited decreased functional connectivity (FC) in the left precuneus (PCUN) of the default mode network (DMN), the right middle temporal gyrus (MTG) of the executive control network (ECN), and the right median cingulate and paracingulate gyri (MCG) of the attention network (ATN), compared with the LDE group. Additionally, there was an increase in FC in the right orbital part of the middle frontal gyrus (ORBmid) of the salience network (SAN), compared with the LDE group. The inter-network analysis revealed increased FC between the visual network (VN) and basal ganglia (BG) and decreased FC between the sensorimotor network (SMN) and DMN, SMN and ATN, SMN and auditory network (AUN), and DMN and SAN in the HDE group, compared with the LDE group. There was a significant negative correlation between altered FC values in MTG and total CARS scores in subjects (r = - 0.18, p = 0.018).  Conclusion: ASD children with prolonged ST often exhibit lower DQ of language development and more severe autistic characteristics. The alteration of intra- and inter-network FC may be a key neuroimaging feature of the effect of prolonged ST on neurodevelopment in ASD children.  Clinical trial registration: ChiCTR2100051141. What is Known: • Prolonged ST has adverse effects on autistic characteristics and language development. • Neuroimaging technology may help to further explain the role of prolonged ST in ASD. What is New: • This is the first study to explore the impact of ST on intra- and inter-network FC in children with ASD. • ASD children with prolonged ST have atypical changes in intra- and inter-brain network FC.

Vitamin D3 improves iminodipropionitrile-induced tic-like behavior in rats through regulation of GDNF/c-Ret signaling activity.

Children with chronic tic disorders (CTD), including Tourette syndrome (TS), have significantly reduced serum 25-hydroxyvitamin D [25(OH)D]. While vitamin D3 supplementation (VDS) may reduce tic symptoms in these children, its mechanism is unclear. The study aim was to investigate the effects and mechanisms of vitamin D deficiency (VDD) and VDS on TS model behavior. Forty 5-week-old male Sprague-Dawley rats were randomly divided into (n = 10 each): control, TS model, TS model with VDD (TS + VDD), or TS model with VDS (TS + VDS; two intramuscular injections of 20,000 IU/200 g) groups. The VDD model was diet-induced (0 IU vitamin D/kg); the TS model was iminodipropionitrile (IDPN)-induced. All groups were tested for behavior, serum and striatal 25(OH)D and dopamine (DA), mRNA expressions of vitamin D receptor (VDR), glial cell line-derived neurotrophic factor (GDNF), protooncogene tyrosine-protein kinase receptor Ret (c-Ret), and DA D1 (DRD1) and D2 (DRD2) receptor genes in the striatum. TS + VDD had higher behavior activity scores throughout, and higher total behavior score at day 21 compared with TS model. In contrast, day 21 TS + VDS stereotyped behavior scores and total scores were lower than TS model. The serum 25(OH)D in TS + VDD was < 20 ng/mL, and lower than control. Striatal DA of TS was lower than control. Compared with TS model, striatal DA of TS + VDD was lower, while in TS + VDS it was higher than TS model. Furthermore, mRNA expression of VDR, GDNF, and c-Ret genes decreased in TS model, and GDNF expression decreased more in TS + VDD, while TS + VDS had higher GDNF and c-Ret expressions. VDD aggravates, and VDS ameliorates tic-like behavior in an IDPN-induced model. VDS may upregulate GDNF/c-Ret signaling activity through VDR, reversing the striatal DA decrease and alleviating tic-like behavior.

Parent-child interaction related to brain functional alterations and development outcomes in autism spectrum disorder: A study based on resting state-fMRI.

BACKGROUND: Limited study has investigated the influence of parent-child interaction on brain functional alterations and development outcomes of autism spectrum disorder (ASD) children. This pilot study aimed to explore the relationship between parent-child interaction, brain functional activities and development outcomes of ASD children. METHODS: and Procedures: 653 ASD with an average age of 41.06 ± 10.88 months and 102 typically developmental (TD) children with an average age of 44.35 ± 18.39 months were enrolled in this study, of whom 155 ASD completed brain rs-fMRI scans. The amplitude of low-frequency fluctuations (ALFF) and regional homogeneity (ReHo) measured using resting-state functional magnetic resonance imaging (rs-fMRI) data reflect local brain function. The parent-child interaction was assessed by the Chinese Parent-child Interaction Scale (CPCIS). Childhood Autism Rating Scale (CARS) and developmental quotient (DQ) indicated development outcomes. OUTCOMES AND RESULTS: Total CPCIS score was negatively correlated with CARS total score, and positively correlated with DQ. The frequency of parent-child interaction was negatively correlated with ALFF values in the left median cingulate and paracingulate gyri (DCG.L) and ReHo values in the right superior frontal gyrus, medial (SFGmed.R)(P < 0.05, FDR correction). ALFF values in the DCG.L and ReHo values in the SFGmed.R play complete mediating roles in the relationship between parent-child interaction and performance DQ. CONCLUSION AND IMPLICATIONS: This study suggest that parent-child interaction has an impact on autistic characteristics and DQ of ASD children. Local brain regions with functional abnormalities in the DCG.L and SFGmed.R may be a crucial factors affecting the performance development of ASD children with reduced parent-child interaction.

Efficacy of Paravertebral Injection of Interferon-α2b Combined with High-Voltage, Long-Term Pulsed Radiofrequency in DRG in Mitigation of Postherpetic Neuralgia: A Retrospective Study.

OBJECTIVE: This investigation aims to evaluate the effectiveness of the paravertebral injection of recombinant human interferon-α2b in conjunction with high-voltage, long-term, pulsed radiofrequency (PRF) in the dorsal root ganglion for the mitigation of postherpetic neuralgia (PHN). METHODS: This retrospective study included 84 individuals with acute PHN. The participants were divided into 3 groups. Group H was treated with interferon-α2b combined with high-voltage long-term PRF. Group C was treated with a combination of high-voltage, long-term PRF and a paravertebral injection (without recombinant human interferon-α2b), and group I was treated with interferon-α2b only. All the patients in the 3 groups were orally administered a 5-mg morphine hydrochloride quick-release tablet when a burst of pain occurred during treatment. The numerical rating scale for pain score, the interleukin-6 and galectin-3 levels, and the incidence of PHN were documented before and after therapy. RESULTS: The pain intensity of all individuals decreased after therapy. Compared with group C, the numerical rating scale scores for group H were significantly reduced at 4, 8, and 12 weeks following therapy, and the PHN incidence was significantly lower. Compared with prior treatment, the recommended dosage of gabapentin capsules and immediate-release morphine hydrochloride tablets was reduced for group H. Compared with group C, the requirement for orally administrated gabapentin capsules and morphine hydrochloride tablets in group H was reduced significantly after treatment. No serious adverse reactions occurred in any of the 3 groups. CONCLUSIONS: Within the context of treatment of acute PHN, the injection of interferon-α2b in conjunction with high-voltage, long-term application of PRF is more effective than PRF or the injection of interferon-α2b alone.

Circulating retinol and 25(OH)D contents and their association with symptoms in children with chronic tic disorders.

The present study measured serum levels of vitamin A (VA) and vitamin D (VD) in children with chronic tic disorders (CTD) and investigated their potential association with CTD and comorbidity of attention deficit hyperactivity disorder (ADHD) and the association of their co-insufficiencies or deficiencies with CTD symptoms. A total of 176 children (131 boys and 45 girls, median age of 9 years) with CTD were recruited as the CTD group. During the same period, 154 healthy children were selected as the healthy control (HC) cohort. Circulating retinol and 25-hydroxyvitamin D (25[OH]D) levels were measured for all participants using high-performance liquid chromatography (HPLC) and tandem mass spectrometry. The Yale Global Tic Severity Scale (YGTSS) was employed for the assessment of tic status and CTD impairment. The Swanson, Nolan, and Pelham Rating Scale (SNAP-IV) and the Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS) were used to evaluate comorbidity symptoms. CTD pediatric participants exhibited markedly diminished circulating retinol and 25(OH)D levels compared to HCs. Moreover, VA and VD deficiencies and their co-insufficiencies/deficiencies were more prevalent in CTD participants than HCs. Circulating 25(OH)D levels were inversely proportional to the YGTSS motor tic scores. YGTSS scores in CTD children with only VA or VD insufficiency or deficiency or with VA and VD co-insufficiency/deficiency did not differ from those in CTD children with normal VA and VD. CTD children with comorbid ADHD displayed reduced circulating retinol and 25(OH)D concentrations and elevated prevalence of VD deficiency compared to CTD participants without comorbid ADHD. Lower serum retinol content was intricately linked to the presence of elevated CTD and comorbid ADHD. VA and VD deficiencies and their co-insufficiencies/deficiencies were markedly enhanced in CTD pediatric participants compared to HCs. Lower VA concentration was linked to the presence of enhanced CTD and comorbid ADHD. Therefore, children with CTD, especially with comorbid ADHD, may be at a higher risk of VA or VD deficiency, which may prompt the clinicians to consider whether blood tests for VA and VD in CTD children would be helpful for clinical care.

Intestinal Symptoms Among Children aged 2-7 Years with Autism Spectrum Disorder in 13 Cities of China.

BACKGROUND: Autism spectrum disorder (ASD) is a multifactorial, pervasive, neurodevelopmental disorder, of which intestinal symptoms collectively represent one of the most common comorbidities. METHODS: In this study, 1,222 children with ASD and 1,206 typically developing (TD) children aged 2-7 years were enrolled from 13 cities in China. Physical measurement and basic information questionnaires were conducted in ASD and TD children. The Childhood Autism Rating Scale (CARS), Social Responsiveness Scale (SRS), and Autism Behavior Checklist (ABC) were used to evaluate the clinical symptoms of children with ASD. The six-item Gastrointestinal Severity Index (6-GSI) was used to evaluate the prevalence of intestinal symptoms in two groups. RESULTS: The detection rates of constipation, stool odor, and total intestinal symptoms in ASD children were significantly higher than those in TD children (40.098% vs. 25.622%, 17.021% vs. 9.287%, and 53.601% vs. 41.294%, respectively). Autistic children presenting with intestinal comorbidity had significantly higher scores on the ABC, SRS, CARS, and multiple subscales than autistic children without intestinal symptoms, suggesting that intestinal comorbidity may exacerbates the core symptoms of ASD children. CONCLUSION: Intestinal dysfunction was significantly more common in autistic than in TD children. This dysfunction may aggravate the core symptoms of children with ASD.

Relationship among low baseline muscle mass, skeletal muscle quality, and mortality in critically ill children.

BACKGROUND: Studies in adults have shown that low baseline muscle mass at intensive care unit (ICU) admission was associated with poor clinical outcomes. However, no information on the relationship between baseline muscle quality or mass and clinical outcomes in critically ill children was found. METHODS: 3775 children were admitted to the pediatric ICU (PICU), 262 were eligible for inclusion. Abdominal computed tomography was performed to assess baseline skeletal muscle mass and quality. Patients were categorized to normal or low group based on the cutoff value for predicting hospital mortality of the skeletal muscle index (SMI; 30.96 cm2 /m2 ) and skeletal muscle density (SMD; 41.21 Hounsfield units). RESULTS: Body mass index (BMI) (18.07 ± 4.44 vs 15.99 ± 4.51) and BMI-for-age z score (0.46 [-0.66 to 1.74] vs -0.87 [-1.69 to 0.05]) were greater in the normal-SMI group, the length of PICU stay was longer in the low-SMI group (16.00 days [8.50-32.50] vs 13.00 days [7.50-20.00]), and the in-PICU mortality rate in the normal-SMI group (10.00%) was lower than the low-SMI group (22.6%). Children with low SMD had a higher in-PICU mortality rate (25.6% vs 7.7%), were younger (36.00 months [12.00-120.00] vs 84.00 months [47.50-147.50]) and weighed less (16.40 kg [10.93-37.25] vs 23.00 kg [16.00-45.00]). Mortality was greater in patients with lower SMD and prolonged hospital stay (log-rank, P = 0.007). SMD was an independent predictor for length of PICU stay and in-PICU mortality. CONCLUSIONS: Low baseline skeletal muscle quality in critically ill children is closely tied with a higher in-PICU mortality and longer PICU stay and is an independent risk factor for unfavorable clinical outcomes.

Analysis of the Risk Factors and a Prediction Model for Postherpetic Trigeminal Neuralgia Recurrence After Extracranial Nonsemilunar Ganglion Radiofrequency Thermocoagulation.

BACKGROUND: Extracranial nonsemilunar ganglion radiofrequency thermocoagulation in the treatment of postherpetic trigeminal neuralgia has significant clinical effects. However, the related risk factors for its recurrence have not been studied. OBJECTIVE: This study aimed to investigate the risk factors for the recurrence of postherpetic trigeminal neuralgia after extracranial nonsemilunar ganglion radiofrequency thermocoagulation, and to construct a recurrence prediction model. STUDY DESIGN: This is a single-center, retrospective observational study. SETTING: The study was conducted in the Department of Pain, Affiliated Hospital of Jiaxing College, Jiaxing, People's Republic of China. METHODS: A total of 76 patients with postherpetic trigeminal neuralgia admitted to the First Hospital of Jiaxing from July 2013 through October 2021 were retrospectively analyzed. All patients were treated with computed tomography-guided extracranial nonsemilunar segment radiofrequency therapy. The Kaplan-Meier method was used for survival analysis, the log-rank test was used, and the Cox proportional hazards regression model was used to analyze the clinical factors affecting postherpetic trigeminal neuralgia recurrence after extracranial nosemilunar ganglia radiofrequency thermocoagulation; in addition, a recurrence prediction model was established. RESULTS: Patients were followed-up for 12 months. A univariate analysis showed that age and disease duration are the factors affecting postherpetic trigeminal neuralgia recurrence after extracranial nonsemilunar ganglion radiofrequency thermocoagulation (P < 0.05). A multivariate Cox proportional hazards regression analysis showed that age and disease duration were independent influencing factors. The recurrence risk function model is expressed as follows. H (t) = h0exp (1.116 X1 + 1.340 X2), where X1 and X2 represent age and disease duration, respectively. The likelihood ratio of the model was tested, and the likelihood ratio was 195.776, showing statistical significance. LIMITATIONS: We look forward to increasing the sample size in subsequent studies and exploring relevant conclusions in randomized controlled trials. CONCLUSION: A short disease duration and young age can reduce the risk of recurrence after extracranial nonsemilunar ganglia radiofrequency thermocoagulation in patients with postherpetic trigeminal neuralgia. Our established recurrence prediction model can provide a reference for clinical diagnosis and treatment.

Nomogram for Predicting the Recurrence Rate in Selective Radiofrequency Thermocoagulation of the Trigeminal Nerve Based on Regression via Least Absolute Shrinkage and Selection Operator.

BACKGROUND: Computed tomography-guided percutaneous selective radiofrequency thermocoagulation (RFT) of the trigeminal nerve is a novel, minimally invasive technique for the treatment of trigeminal neuralgia, but the high recurrence rate after surgery might pose a serious problem. OBJECTIVES: The purpose of this study was to explore the risk factors affecting the recurrence rate after RFT and to predict the recurrence rate and provide evidence for the early prediction. STUDY DESIGN: A single-center retrospective study. SETTING: This study was carried out in the Affiliated Hospital of Jiaxing University in China. METHODS: One hundred thirty-nine patients were included in this study. The cumulative survival rates according to temperature and type of pain were estimated by the Kaplan-Meier analysis. The least absolute shrinkage and selection operator Cox regression model was used to build the nomogram. Time-independent receiver operating characteristic curve analysis confirmed the signature's predictive capacity. A calibration curve was generated to judge the accuracy of absolute risk predictions, and Brier scores were used to quantitatively evaluate the calibration. Decision curve analysis was applied to comprehensively evaluate the clinical effectiveness of the model. A multiparameter nomogram was used to analyze the scores and predict the risk of relapse. RESULTS: Three predictors were screened by multivariate Cox regression analysis. Pain grade (refit hazard ratio [HR]: 1.6807; 95% confidence interval [CI]: 1.1963-2.3613) and type of pain (HR: 6.2802; 95% CI: 3.3705-11.7021) were considered to be risk factors affecting the recurrence rate after RFT, while temperature (HR: 0.5203; 95% CI: 0.2859-0.9468) was identified as a protective factor. The recurrence rate within 2 years in 85°C group was 51.09%, while that in 95°C group was 29.79%. The nomogram exhibited good discrimination and calibration. Compared with the preoperative period, all of the patients' postoperative Numeric Rating Scale scores (NRS-11)decreased significantly (P < 0.05). The main postoperative complication was numbness, with a gradual decrease in the Barrow Neurological Institute score over time. Autonomic symptoms and decrease of masticatory muscle function were the secondary postoperative complications, and no other adverse events were observed. Overall patient satisfaction at 2 years postoperatively was 7.83 ± 1.93. LIMITATIONS: This study contains a small sample size from a single center and the conclusion of randomized controlled trials will be more convincing. CONCLUSIONS: Increasing temperature can effectively reduce the recurrence rate after RF, and the combination of atypical pain and higher NRS-11s could be a risk factor increasing the recurrence rate. The novel nomogram exhibited favorable survival stratification accuracy and shown a great potential for screening high-risk groups and evaluating the risk of recurrence rate.

Both epilepsy and anti-seizure medications affect bone metabolism in children with self-limited epilepsy with centrotemporal spikes.

OBJECTIVE: Bone metabolism can be influenced by a range of factors. We selected children with self-limited epilepsy with centrotemporal spikes (SeLECTS) and lifestyles similar to those of healthy children to control for the confounding factors that may influence bone metabolism. We aimed to identify the specific effects of epilepsy and/or anti-seizure medications (ASMs) on bone metabolism. METHODS: Patients with SeLECTS were divided into an untreated group and a monotherapy group, and the third group was a healthy control group. We determined the levels of various biochemical markers of bone metabolism, including procollagen type I nitrogenous propeptide (PINP), alkaline phosphatase (ALP), osteocalcin (OC), collagen type I cross-linked C-telopeptide (CTX), calcium, magnesium, phosphorus, parathyroid hormone (PTH), and vitamin D3 (VD3 ). RESULTS: A total of 1487 patients (from 19 centers) were diagnosed with SeLECTS; 1032 were analyzed, including 117 patients who did not receive any ASMs (untreated group), 643 patients who received only one ASM (monotherapy group), and 272 children in the healthy control group. Except for VD3 , other bone metabolism of the three groups were different (p < .001). Bone metabolism was significantly lower in the untreated group than the healthy control group (p < .05). There were significant differences between the monotherapy and healthy control group in the level of many markers. However, when comparing the monotherapy and untreated groups, the results were different; oxcarbazepine, levetiracetam, and topiramate had no significant effect on bone metabolism. Phosphorus and magnesium were significantly lower in the valproic acid group than the untreated group (adjusted p < .05, Cliff's delta .282-.768). CTX was significantly higher in the lamotrigine group than in the untreated group (adjusted p = .012, Cliff's delta = .316). SIGNIFICANCE: Epilepsy can affect many aspects of bone metabolism. After controlling epilepsy and other confounders that affect bone metabolism, we found that the effects of ASMs on bone metabolism differed. Oxcarbazepine, levetiracetam, and topiramate did not affect bone metabolism, and lamotrigine corrected some of the abnormal markers of bone metabolism in patients with epilepsy.

Blocking Pannexin-1 Channels Alleviates Thalamic Hemorrhage-Induced Pain and Inflammatory Depolarization of Microglia in Mice.

Central post-stroke pain (CPSP) is a neuropathic pain syndrome that frequently occurs following cerebral stroke. The pathogenesis of CPSP is mainly due to thalamic injury caused by ischemia and hemorrhage. However, its underlying mechanism is far from clear. In the present study, a thalamic hemorrhage (TH) model was established in young male mice by microinjection of 0.075 U of type IV collagenase into the unilateral ventral posterior lateral nucleus and ventral posterior medial nucleus of the thalamus. We found that TH led to microglial pannexin (Panx)-1, a large-pore ion channel, opening within the thalamus accompanied with thalamic tissue injury, pain sensitivities, and neurological deficit, which were significantly prevented by either intraperitoneal injection of the Panx1 blocker carbenoxolone or intracerebroventricular perfusion of the inhibitory mimetic peptide 10Panx. However, inhibition of Panx1 has no additive effect on pain sensitivities upon pharmacological depletion of microglia. Mechanistically, we found that carbenoxolone alleviated TH-induced proinflammatory factors transcription, neuronal apoptosis, and neurite disassembly within the thalamus. In summary, we conclude that blocking of microglial Panx1 channels alleviates CPSP and neurological deficit through, at least in part, reducing neural damage mediated by the inflammatory response of thalamic microglia after TH. Targeting Panx1 might be a potential strategy in the treatment of CPSP.

The challenges of screen time in children with typical development and children with developmental disorders during COVID-19 pandemic.

Background: The significant lifestyle changes that occurred during the lockdown period associated with the COVID-19 pandemic may have had many potential adverse effects on children, in particular, sedentary screen exposure among children, including those with developmental disorders. We conducted a cross-sectional study to investigate and compare the screen time and outdoor activity time of children with typically development (TD) and those with developmental disorders during and before the emergence of COVID-19, and identified the risk factors related to screen time during the COVID-19 pandemic. Methods: A total of 496 children were surveyed via online questionnaires. Parents or/and children filled in the online questionnaire, including basic characteristics, screen time, outdoor activity time, and other related factors. The Statistical Product and Service Solutions software was used to analyze all data. Results: Children spent less time outdoors (t=14.774, P<0.001) and more time on electronic screens (t=-14.069, P<0.001) during the lockdown period of COVID-19, compared to the periods before COVID-19. Age (P=0.037), pre-COVID-19 screen time (P=0.005), screen time used for learning/education (P<0.001), screen time of siblings (P=0.007), and use of screen devices as electronic babysitters (P=0.005) were risk factors for screen time during the COVID-19 pandemic, while restrictive use of electronic devices by parents (P<0.05) was a protective factor. The screen time of children with autism spectrum disorder (ASD) or attention deficit hyperactivity disorder (ADHD) was significantly longer than children with TD before COVID-19 pandemic, but there is no statistical difference during the COVID-19 pandemic. Conclusions: During the COVID-19 pandemic, children's screen exposure time increased, and outdoor activities decreased significantly. This represents a significant challenge, and we should focus our efforts on managing children's screen time and promoting healthier lifestyles, including children with typical development, as well as those with developmental disorders.

Early Diagnosis of Herpes Zoster Neuralgia: A Narrative Review.

BACKGROUND: Early intervention reduces the incidence of postherpetic neuralgia (PHN). Typical shingles are easy to diagnose; however, there is no clear diagnostic method for neuralgia symptoms manifested before the onset of the rash, which can easily cause misdiagnosis. This not only increases the patient's pain, medical expenses, and mental burden, but more importantly, delays the valuable time for early treatment of shingles, and increases the probability of complications and PHN. OBJECTIVE: In this paper, the diagnostic methods of preherpetic neuralgia were summarized and analyzed, and the current challenges were put forward to provide directions for the early diagnosis of herpes zoster (HZ) in the future. METHODS: PubMed, and China National Knowledge Infrastructure (CNKI) libraries were searched using the terms "herpes zoster," "before the blistering," "diagnosis," and "neuralgia." Clinical trials, reviews, and case reports were collected and reviewed. The period of literature search is from 1 January 1980 to 1 October 2022. RESULTS: The early diagnosis of herpes zoster neuralgia can reduce misdiagnosis and mistreatment, and timely and effective intervention can significantly reduce the incidence of PHN. The body may possess a mechanism that limits the local breakthrough of the virus in the skin, causing blistering later than the onset of pain. Changes in the plasma proteins of patients with varicella-zoster virus shingles neuralgia may be used as an early diagnostic indicator in patients with HZ neuralgia before eruption. CONCLUSION: Early diagnosis of HZ neuralgia before eruption can facilitate timely targeted treatment, thereby reducing the incidence of PHN. Proteomic quantitative analysis and validation results can serve as a simple, micro, rapid, and accurate diagnostic method.
