Objective:To study the relationship and the role of leptin in children with biliary atresia and hepatic fibrosis to provide a treatment basis for these patients.Methods:The clinical data of children with biliary atresia or congenital biliary dilatation (CBD) who underwent surgical treatment at the Department of General Surgery of Tianjin Children's Hospital from August 2019 to August 2021 were retrospectively analyzed. Of 31 children included in this study, there were 14 males and 17 females, with age of 60 (30, 63) d. Children with biliary atresia served as the study group ( n=26) and children with CBD served as the control group ( n=5). Leptin protein, α-smooth muscleactin (α-SMA) and phosphorylation of extracellular-regulated protein kinase 1/2 (p-ERK1/2) in liver tissues were detectd by immunohistochemistry (IHC). The expression level of leptin mRNA in liver tissues were detected by quantitative real-time reverse transcription polymerase chain reaction (qRT-PCR). Results:The average optical density values of leptin protein, α-SMA protein and p-ERK1/2 protein in the liver tissues of children in the study group were significantly higher than the control group ( P<0.05). The expression levels of leptin, α-SMA and p-ERK1/2 in liver tissues of children with biliary atresia significantly increased with increase in fibrosis degree ( P<0.05). The expression level of leptin in liver tissues of children with biliary atresia was positively correlated with the liver fibrosis grade ( rs=0.876), α-SMA ( r=0.723) and p-ERK1/2 ( r=0.725) ( P<0.01). The results of qRT-PCR showed that the content of leptin mRNA in liver tissues of children with biliary atresia was significantly higher than that of children with CBD ( P<0.05). Conclusion:Expressions of leptin increased with aggravation of degrees of hepatic fibrosis in biliary atresia. Leptin may be involved in activation of HSCs through the ERK1/2 signaling pathway in the process of hepatic fibrosis due to biliary atresia.

Fixed daily cost, total cost and C/E of ERF group was RMB 59.0 yuan, RMB 590.5 yuan and 648.9, respectively; and the eradication rate was 91.0%(61/67). Fixed daily cost, total cost and C/E of EMFB group was RMB 32.9 yuan, RMB 329.1 yuan and 350.9, respectively; and the eradication rate was 93.8%(61/65). Conclusions Rifabutin and furazolidone included triple regimen and minocycline plus furazolidone included quadruple regimen both have good efficacy, safety and compliance in the eradication of refractory H. pylori infection, and the latter is better.

Objective Based on the theory of"gut-brain",this study explored the effect of acupuncture on the gut microbiota and central inflammation in migraine model rats,in order to explore the mechanism of acupuncture in the treatment of migraine from the perspective of"gut-brain".Methods The migraine rat model was established by subcutaneous injection of nitroglycerin.They were randomly divided into a model group and an acupuncture group,with 6 rats in each group,and a control group with 6 rats for conventional binding and fixation.Before modeling and on the 1st,5th,and 9th days after modeling,each group used electronic VonFrey to measure the plantar mechanical pain threshold of rats.After the experiment,Elisa was used to detect the expression levels of inflammatory factors IL-6 and TNF-α in the central trigeminal spinal nucleus of the rats in each group.Three-generation Pacbio full-length microbial diversity sequencing was used to perform 16S full-length rDNA sequencing on each group of fecal samples to detect the operational taxonomic unit(OTU)clustering and its abundance,Alpha diversity index,Beta diversity index,species among the samples in each group.differences in abundance.Results In migraine model rats,plantar mechanical pain threshold was significantly decreased(P<0.01),central IL-6 and TNF-α contents were significantly increased(P<0.01),and the structure and abundance of gut microbiota were abnormal.change(P<0.01).Continuous acupuncture treatment can significantly increase the plantar mechanical pain threshold in migraine rats(P<0.01),regulate the diversity of gut microbiota in migraine rats,increase Lactobacillus murine,and reduce the abundance of Lactobacillus enterobacteriaceae.degree(P<0.05),and decreased the levels of IL-6 and TNF-α in the central nervous system of migraine model rats(P<0.01).Conclusion Acupuncture can exert the"gut-brain"anti-inflammatory and analgesic effect of acupuncture in the treatment of migraine by regulating the gut microbiota structure and the expression of central IL-6 and TNF-α inflammatory factors in migraine model rats.

Objective:To explore the lesion characteristics and predictors of invasive coronary angiography (ICA)-verified obstructive lesions with fractional flow reserve (FFR)>0.80, that is, anatomy-function mismatch.Methods:A total of 515 obstructive vessels in 419 coronary disease patients from 11 Chinese medical centers undergoing coronary CT angiography and ICA and FFR were retrospectively analyzed. All vessels had one target lesion with diameter stenosis ≥50 % by ICA. There were 229 vessels in the match group (FFR≤0.80) and 286 vessels in the mismatch group (FFR>0.80). The lesion characteristics including lesion territory, the distance of the coronary artery ostium to the proximal end of the lesion, minimum lumen area, reference lumen area, plaque length and burden, plaque volume and component volume, remodeling index and plaque morphological complexity were measured and compared between the two groups. Optimal thresholds of quantitative plaque characteristics were defined by Yoden index. Logistic regression analysis was used to analyze the predictors of anatomy-function mismatch. Area under receiver operating characteristic curve (AUC) was used to analyze the ability of different lesion features to predict mismatched lesions.Results:The coronary stenosis, plaque burden and length, plaque volume (including each component volume) in the mismatch group were smaller than those in the match group, and FFR, minimum lumen area were larger (all P<0.05). Left anterior descending artery (LAD) lesion and severe complex plaque were more common in the match group than the mismatch group with a statistically significant difference. Univariate logistic regression analysis showed that LAD lesion, minimum lumen area>4 mm 2, plaque burden and length, plaque calcification volume<27 mm 3, plaque lipid volume<30 mm 3, plaque fiber volume<150 mm 3 and plaque morphological complexity were predictiors of anatomic function mismatched lesions; Multivariate logistic regression showed that the minimum lumen area>4 mm 2 (OR=3.371, 95%CI 1.903-5.973, P<0.001), plaque lipid volume<30 mm 3 (OR=3.014, 95%CI 1.691-5.373, P<0.001), plaque morphological complexity (mild OR=17.772, 95%CI 8.072-39.128, P<0.001, moderate OR=6.383, 95%CI 3.739-10.896, P<0.001) were independent predictors of mismatched lesions. The AUC of the model based on the minimum lumen area, plaque lipid volume and morphological complexity was 0.824, which was superior to either of the plaque feature alone ( P<0.001). Conclusions:The minimum lumen area, lipid volume and plaque morphological complexity are independent predictors of the anatomical-functional mismatch lesions, and the combination can significantly improve the prediction value.

OBJECTIVE Cognitive deficit is a com-mon comorbidity in temporal lobe epilepsy(TLE)and that is not well controlled by current therapeutics.Currently,how epileptic seizure affects cognitive performance remains largely unclear.The subiculum is the major out-put of the hippocampus,which projects to entorhinal cor-tex and other more distinct brain regions.Physiologically,the subiculum codes spatial working memory and naviga-tion information including place,speed,and trajectory.Importantly,prior studies have noted the importance of the subiculum in the beginning,spreading,and generaliz-ing process of hippocampal seizure.How seizure-activated neurons in subiculum participate in cognitive impairment remains largely elusive.METHODS In this study,we sought to label the subicular seizure-activated c-fos+ neu-rons with a special promoter with enhanced synaptic activity-responsive element E-SARE in the subiculum,combined with chemogenetics and designer receptors exclusively activated by designer drugs(DREADDs),Ca2+ fiber photometry approaches,and behavioral tasks,to reveal the role of these neurons in cognitive impairment in epilepsy.RESULTS We found that chemogenetic inhibi-tion of subicular seizure-tagged c-fos+ neurons(mainly CaMK Ⅱ α+ glutamatergic neurons)alleviates seizure generalization and improves cognitive performance in the hippocampal CA3 kindling TLE model.While inhibition of seizure-labeled c-fos+ GABAergic interneuron shows no effect on seizure and cognition.As a comparison,che-mogenetic inhibition of the whole subicular CaMK Ⅱ α+ neuron impairs cognitive function in na?ve mice in basal condition.Notably,inhibition of subicular seizure-tagged c-fos+ neurons enhances the recruitment of cognition-responsive c-fos+ neurons via increasing neural excitability during cognition tasks.CONCLUSION Our results dem-onstrate that subicular seizure-activated c-fos+ neurons contribute to cognitive impairment in TLE,suggesting sei-zure-tagged c-fos+ neurons as the potential therapeutic target to alleviate cognitive impairment in TLE.
