Objective To analyze the risk factors of post-ERCP pancreatitis (PEP) and to evaluate the relationship between cannulation time and PEP.Methods The data of cannulation time in 1 625 patients who underwent ERCP from 2010 to 2012 were retrospectively studied.The risk factors associated with PEP were analyzed by univariate and multivariate Logistic regression analysis.The effect of different cannulation time on PEP was evaluated.Results The incidence of overall PEP was 4.6％ (75/1 625) including 4.1％ (67/1 625)of mild and 0.5％ (8/1 625)of moderate-to-severe.Univariate analysis revealed that diabetes mellitus (P =0.02),choledocholithiasis (P =0.02),malignant biliary stenosis (P =0.007),duodenal stenosis (P =0.029),precut (P＜0.01),cannulation time ≥ 8 min (P＜0.01),blood platelet count ≥ 180× 109/L(P =0.089),alkaline phosphatase ≥ 120 U/L (P =0.083) and total bilirubin ≥ 17.1 μmol/L (P =0.094)were associated with PEP.Multivariate analysis revealed that precut (OR=1.93,95％CI:1.10-3.39,P=0.022),cannulation time ≥8 min (OR =3.50,95％CI:2.00-6.13,P＜0.01) and duodenum stenosis (OR=2.92,95％CI:1.08-7.86,P=0.034) were independent risk factors of PEP.Within 30 min of cannulation,longer cannulation time was accompanied with higher PEP rate.Conclusion The cannulation time is an independent risk factor of PEP.Overall PEP is increased when cannulation time is more than 8 min.

Neurons in the laterodorsal tegmentum (LDTg) and pedunculopontine tegmental nucleus (PPTg) play important roles in central autonomic circuits of the kidney. In this study, we used a combination of retrograde tracers pseudorabies virus (PRV)-614 and fluorescence immunohistochemistry to characterize the neuroanatomic substrate of PPTg and LDTg innervating the kidney in the mouse. PRV-614-infected neurons were retrogradely labeled in the rostral and middle parts of LDTg, and the middle and caudal parts of PPTg after tracer injection in the kidney. PRV-614/TPH double-labeled neurons were mainly localized in the rostral of LDTg, whereas PRV-614/TH neurons were scattered within the three parts of LDTg. PRV-614/TPH and PRV-614/TH neurons were located predominantly in the caudal of PPTg (cPPTg). These data provided direct neuroanatomical foundation for the identification of serotonergic and catecholaminergic projections from the mid-brain tegmentum to the kidney.

ObjectiveTo investigate the status of sleep insufficiency in children and adolescents with mental disorders and related influencing factors. MethodsA total of 131 children and adolescents who were admitted to the Third People's Hospital of Fuyang from February to June 2021 and met the diagnostic criteria of International Classification of Diseases， tenth edition （ICD-10） for schizophrenia， depression or childhood-onset mood disorders were selected as the research subjects. A self-compiled questionnaire was used to collect the general demographic information， sleep status， lifestyle habits， family and school status of the selected individuals. The demographic information was compared between sleep sufficiency group and sleep insufficiency group. Spearman rank correlation was used to screen the influencing factors. Results① Among 131 children and adolescents with mental disorders， 93 cases （71.0%） had sleep insufficiency. There were significant differences between sleep insufficiency group and sleep sufficiency group in terms of disease types （χ²=8.798， P=0.012）， experience of being beaten in recent 6 months （χ²=3.427， P=0.035）， being scolded in recent 6 months （χ²=4.145， P=0.031）， and cyberbullying over the past year （χ²=4.187， P=0.041）. ② Among patients with sleep insufficiency， 77 cases （82.8%） reported difficulty in falling asleep and 69 cases （74.2%） reported nocturnal awakenings. ③ Sleep insufficiency in children and adolescents with mental disorders was positively correlated with the experience of being scolded （r=0.210， P=0.037） or beaten （r=0.145， P=0.023） over the past 6 months and cyberbullying over the past year （r=0.179， P=0.041）. ConclusionChildren and adolescents with mental disorders suffer a high risk of sleep insufficiency， and is closely associated with depressive disorder， experience of being scolded or beaten over the past 6 months， and cyberbullying over the past year.

Primary ciliary dyskinesia (PCD) is a hereditary disease characterized by airway mucociliary clearance dysfunction. The estimated prevalence of PCD is 1꞉10 000 to 1꞉20 000. The main respiratory manifestations in children are cough, expectoration, chronic rhinitis, sinusitis, and chronic otitis media, while the most common symptoms in adults are chronic sinusitis, bronchiectasis, and infertility. About 50% of patients with certain PCD-related gene variants are combined with situs inversus, and the incidence of congenital heart disease is also high. The pathogenesis behind PCD is that gene variants cause structural or functional disorders of respiratory cilia and motile cilia of other organs, leading to a series of heterogeneous clinical manifestations, which makes it difficult to identify and diagnose PCD. Combining different disease screening tools and understanding the relationship between genotypes and phenotypes may facilitate early diagnosis and treatment for PCD.

Primary ciliary dyskinesia (PCD) is a congenital, motile ciliopathy with pleiotropic symptoms. Although nearly 50 causative genes have been identified, they only account for approximately 70% of definitive PCD cases. Dynein axonemal heavy chain 10 (DNAH10) encodes a subunit of the inner arm dynein heavy chain in motile cilia and sperm flagella. Based on the common axoneme structure of motile cilia and sperm flagella, DNAH10 variants are likely to cause PCD. Using exome sequencing, we identified a novel DNAH10 homozygous variant (c.589C > T, p.R197W) in a patient with PCD from a consanguineous family. The patient manifested sinusitis, bronchiectasis, situs inversus, and asthenoteratozoospermia. Immunostaining analysis showed the absence of DNAH10 and DNALI1 in the respiratory cilia, and transmission electron microscopy revealed strikingly disordered axoneme 9+2 architecture and inner dynein arm defects in the respiratory cilia and sperm flagella. Subsequently, animal models of Dnah10-knockin mice harboring missense variants and Dnah10-knockout mice recapitulated the phenotypes of PCD, including chronic respiratory infection, male infertility, and hydrocephalus. To the best of our knowledge, this study is the first to report DNAH10 deficiency related to PCD in human and mouse models, which suggests that DNAH10 recessive mutation is causative of PCD.
