Epilepsy affects over 50 million people worldwide. Drug-resistant epilepsy (DRE) accounts for up to a third of these cases, and neuro-inflammation is thought to play a role in such cases. Despite being a long-debated issue in the field of DRE, the mechanisms underlying neuroinflammation have yet to be fully elucidated. The pro-inflammatory microenvironment within the brain tissue of people with DRE has been probed using single-cell multimodal transcriptomics. Evidence suggests that inflammatory cells and pro-inflammatory cytokines in the nervous system can lead to extensive biochemical changes, such as connexin hemichannel excitability and disruption of neurotransmitter homeostasis. The presence of inflammation may give rise to neuronal network abnormalities that suppress endogenous antiepileptic systems. We focus on the role of neuroinflammation and brain network anomalies in DRE from multiple perspectives to identify critical points for clinical application. We hope to provide an insightful overview to advance the quest for better DRE treatments.

BACKGROUND:Studies have shown that both Panax notoginseng saponins and concentrated growth factor can promote fracture healing,but there are few studies addressing their combined effects on fracture healing.Panax notoginseng saponins may accelerate fracture healing by promoting the release of concentrated growth factor-related factors over a certain period of time. OBJECTIVE:To study the effect of Panax notoginseng saponins on concentrated growth factor release and fracture healing in rats. METHODS:Eighteen 8-week-old Sprague-Dawley rats were numbered and randomly divided into three groups:Panax notoginseng saponins group,model control group and blank group.Panax notoginseng saponins group was fed with Panax notoginseng saponins for 2 weeks.Model control group was given 2 mL of normal saline for 2 weeks and blank group was fed normally.Concentrated growth factor was obtained by the centrifugation method both from the Panax notoginseng saponins group and model control group.After 1 week of normal feeding,all animals underwent modeling for femoral fracture.The Panax notoginseng saponins group and the model control group were implanted with autologous concentrated growth factor,and then the release concentration of growth factors at different time points(1 hour,1,3,5,7,9 and 11 days)were measured by ELISA.Fracture healing was assessed based on postoperative X-ray and hematoxylin-eosin staining of bone tissues. RESULTS AND CONCLUSION:Compared with the model control group,the Panax notoginseng saponins group had higher release concentrations of vascular endothelial growth factor A and transforming growth factor β at 7,9,and 11 days,Platelet-derived growth factor BB at 5,9,and 11 days,and basic fibroblast growth factor at 1-11 days(P<0.01).X-ray examinations indicated that fracture healing in the Panax notoginseng saponins group was better than that in the model control group,and fracture healing in these two groups was better than that in the blank group at 2 months after surgery.Hematoxylin-eosin staining results found that the constituent osteocyte density in the Panax notoginseng saponins group was greater than that in the model control group,and the constituent osteocyte density in these two groups was better than that in the blank group.These findings indicate that Panax notoginseng saponins can increase the concentration of concentrated growth factor-related factors.After intervention with Panax notoginseng saponins,concentrated growth factors are more advantageous in promoting fracture healing in rats.

Objective:To study the clinical effects of modified surgical method with H-uvulopalatopharyngoplasty(H-UPPP)and traditional surgical method in the treatment of obstructive sleep apnea hypopnea syndrome(OSAHS)in children.Methods:The clini-cal data of 364 pediatric patients with OSAHS were retrospectively analyzed.The patients were divided into 2 groups and treated by low-temperature plasma knife radio frequency ablation for bilateral tonsil removal combined with H-UPPP(group A,n=204)and low-temperature plasma knife radio frequency ablation only(group B,n=160)respectively.The operative time,intraoperative bleed-ing,postoperative secondary bleeding,VAS of pain following operation,postoperative traumatic white film shedding time,OAH1,LSaO2,ESS scores and complications of the 2 groups were compared.Results:In group A the operative time,intraoperative bleed-ing,VAS,OAHI and ESS scores were lower than those in group B(P＜0.05),wile postoperative traumatic white film detachment time and LSaO2 were higher(P＜0.05).No statistically significant difference in terms of the number of cases of postoperative seconda-ry bleeding and complications was observed between the 2 groups(P＞0.05).Conclusion:The combination of low-temperature plas-ma radio frequency ablation and H-UPPP for the treatment of OSAHS may provide clear intraoperative view,and may improve the treatment effects.

OBJECTIVE To explore the effect of changing lifestyle diet in the treatment of laryngeal reflux disease(LRPD).METHODS A total of 92 patients with LRPD who received outpatient treatment in the Second Affiliated Hospital of Fujian Medical University from January 2022 to June 2023 were selected as the study control,divided into control group(46 cases)and treatment group(46 cases).The control group was treated with conventional acid suppression and gastric motogenic therapy.The treatment group was treated on the basis of the control group with giving guidance on lifestyle and diet.The changes of reflux symptom index scale(RSI)and reflux sign score scale(RFS)and the clinical efficacy of the two groups were compared 8 weeks and 12 weeks after treatment.RESULTS RSI total score was improved 8 weeks after treatment compared with before treatment in both RSI control group and treatment group(P＜0.05).The total RSI score of 12 weeks after treatment was improved compared with that of 8 weeks after treatment in both control and treatment groups(P＜0.05).The total RFS score at 8 weeks after treatment was improved in both control group and treatment group compared with before treatment(P＜0.05).Compared with 8 weeks after treatment,the total RFS score in both control group and treatment group was improved(P＜0.05).After 8 weeks of treatment,the total effective rate of the control group(60.9%)was compared with that of the treatment group(71.7%),and there was no significant difference between the two groups(χ2=1.335,P=0.513).After 12 weeks of treatment,the total effective rate of the control group(73.9%)was compared with the total effective rate of the treatment group(91.3%),and the difference between the two groups was statistically significant(χ2=6.226,P=0.044).CONCLUSION The change of lifestyle and diet should become an important part of the treatment of LRPD.By adjusting the unhealthy lifestyle and diet,the symptoms of patients can be significantly reduced and better clinical efficacy can be obtained.

Objective To investigate the effects of different dosages of atorvastatin, rosuvastatin, and simvastatin in elderly patients with ST-segment elevation acute myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI). Methods A total of 180 patients with STEMI undergoing PCI were prospectively selected as study subjects and divided into group A, group B, group C, group D, group E, and group F using a random number table method, with 30 patients in each group. The group A received low-dose simvastatin orally, the group B received high-dose simvastatin orally, the group C received low-dose atorvastatin orally, the group D received high-dose atorvastatin orally, the group E received low-dose rosuvastatin orally, and the group F received high-dose rosuvastatin orally. The levels of serum inflammatory factors[interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), high-sensitivity C-reactive protein (hs-CRP)], myocardial injury markers[creatine kinase isoenzyme (CK-MB), cardiac troponin T (cTnT), N-terminal pro-brain natriuretic peptide (NT-proBNP)], cardiac function indicators[left ventricular ejection fraction (LVEF), cardiac index (CI), cardiac output (CO)], as well as the ST-segment resolution, occurrence of adverse cardiovascular events, and adverse reactions were compared among the groups. Results At 1 day and 1 month postoperatively, the levels of IL-6, hs-CRP, and TNF-α decreased successively in groups A, B, C, D, E, and F(P < 0.05). At 1 day and 1 month postoperatively, the levels of cTnT, CK-MB, and NT-proBNP also decreased successively in the groups A, B, C, D, E, and F (P < 0.05). At 1 month postoperatively, the LVEF, CO, and CI increased successively in the groups A, B, C, D, E, and F (P < 0.05). The proportions of patients with ST-segment resolution successively increased in the groups A, B, C, D, E, and F (P < 0.05). There were no statistically significant differences in the total incidence of adverse cardiovascular events and adverse reactions among the groups (P>0.05). Conclusion Both low-dose and high-dose atorvastatin, rosuvastatin, and simvastatin can effectively relieve inflammation reactions, improve myocardial function, and promote ST-segment resolution in elderly patients with STEMI undergoing PCI, with high-dose rosuvastatin showing the best effect.

Background: Feline calicivirus (FCV) is a common pathogen of felids, and FCV vaccination is regularly practiced. The genetic variability and antigenic diversity of FCV hinder the effective control and prevention of infection by vaccination. Improved knowledge of the epidemiological characteristics of FCV should assist in the development of more effective vaccines. Objectives: This study aims to determine the prevalence of FCV in a population of cats with FCV-suspected clinical signs in Hangzhou and to demonstrate the antigenic and genetic relationships between vaccine status and representative isolated FCV strains. Methods: Cats (n = 516) from Hangzhou were investigated between 2018 and 2020. The association between risk factors and FCV infection was assessed. Phylogenetic analyses based on a capsid coding sequence were performed to identify the genetic relationships between strains. In vitro virus neutralization tests were used to assess antibody levels against isolated FCV strains in client-owned cats. Results: The FCV-positive rate of the examined cats was 43.0%. Risk factors significantly associated with FCV infection were vaccination status and oral symptoms. Phylogenetic analysis revealed a radial phylogeny with no evidence of temporal or countrywide clusters. There was a significant difference in the distribution of serum antibody titers between vaccinated and unvaccinated cats. Conclusions This study revealed a high prevalence and genetic diversity of FCV in Hangzhou. The results indicate that the efficacy of FCV vaccination is unsatisfactory. More comprehensive and refined vaccination protocols are an urgent and unmet need.

Objective The aim of this study was to explore the serum 25-(OH) Vitamin D and its correlation with liver function in children who have suffered from non-alcoholic fatty liver disease (NAFLD),and to explore the necessity of vitamin D treatment of NAFLD in children.Methods Forty children with NAFLD diagnosed by imaging were selected from the outpatient of pediatric digestive department of Shengjing Hospital of China Medical University,selected as observation group from July 2017 to August 2019,and 37 healthy children were selected as control group.The clinical data were collected and serum 25-(OH) Vitamin D were detected at the same time.Results There was no significant difference in 25-(OH) Vitamin D among children with NAFLD at different ages and gender (P ＞ 0.05).The level of 25-(OH) Vitamin D in children with NAFLD [(21.30 ±8.77) μg/L]was significantly lower than that in the control group [(28.53 ± 10.18) μg/L] (t =3.343,P ＜ 0.01).The incidence of vitamin D deficiency (＜ 20 μg/L) and insufficiency (＜30 μg/L)in children with NAFLD (35/40 =87.50％) was significantly higher than that in the control group (22/37 =59.46％) (x2 =10.035,P ＜ 0.05).Serum 25-(OH) Vitamin D was negatively correlated with fasting insulin (r =-0.464,P ＜ 0.01) and homeostasis model assessment of insulin resistance (r =-0.444,P ＜0.01),but not correlated with BMI,transaminase level (ALT,AST),uric acid and blood lipid (TG,TC,HDL-C,LDL-C,sd-LDL,Apo-A1,Apo-B).Vitamin D deficiency was the risk factor of NAFLD (OR =1.088,P ＜ 0.01).Conclusion Vitamin D deficiency is common in pediatric NAFLD,which may be a risk factor of NAFLD.The mechanism may be that vitamin D deficiency aggravates insulin resistance and further aggravates liver damage in children with NAFLD.

Objective:To evaluate the effect of imatinib on growth impairment in children with chronic myeloid leukemia (CML-CP) in the chronic phase.Methods:From July 2018 to July 2019, questionnaires were distributed to CML children aged <18 years at the time of diagnosis who were receiving imatinib for at least 3 months or to their parents in China. The height-for-age standard deviation score (HtSDS) and the difference of standard deviation integral (△HtSDS) were used to explore the change in height with imatinib therapy.Results:The data of 238 respondents were included; 138 (58.0% ) respondents were men. The median age at the first diagnosis of CML was 11.0 years (range, 1.4-17.9 years) , and 93 (39.0% ) respondents were at the prepuberty stage. At the time of completing the questionnaires, the median age was 15.0 years (range, 2.0-34.0 years) . The median duration of imatinib therapy was 28 months (range, 3-213 months) . Among all the respondents, the mean HtSDS when completing the questionnaires (-0.063±1.361) was significantly lower than that at the time of starting imatinib treatment (0.391±1.244) ( P<0.001) . Total 71.0% respondents showed growth impairment that was more common in those starting imatinib therapy at prepubertal age than in those starting at pubertal age. Multivariate analysis showed that younger at the start of imatinib therapy ( P<0.001) and longer duration of imatinib therapy ( P<0.001) were significantly associated with severe growth impairment on imatinib therapy. Conclusions:Imatinib induced growth impairment in children with CML-CP. Younger the age of initiation and longer the duration of imatinib therapy, more obvious the effect of imatinib on growth impairment.

Nonalcoholic fatty liver disease (NAFLD) refers to a syndrome of a series of lesions such as simple fatty liver disease, nonalcoholic steatohepatitis, liver fibrosis, and even liver cirrhosis. With the improvement of living standards, there is an increasing number of children with obesity, and the detection rate of NAFLD also tends to increase. Major treatment methods for children with NAFLD include the changes in diet and lifestyle and medication. The article reviews the advances in the treatment of NAFLD in children in recent years.
