ObjectiveTo investigate the feasibility and safety of endoscopic retrograde cholangiopancreatography （ERCP） combined with oral cholangiopancreatography in the treatment of major duodenal papilla gallbladder polyps. MethodsA retrospective analysis was performed for the clinical data of eight patients with choledocholithiasis and gallbladder polyps who underwent ERCP and combined with oral cholangiopancreatography for major duodenal papilla cholecystectomy in Center of Digestive Endoscopy， Jilin People’s Hospital， from May 2022 to June 2024， and related data were collected， including the success rate of surgery， the technical success rate of gallbladder polyp removal， the superselective method of cystic duct， the time of operation， the time of gallbladder polyp removal， and surgical complications. ResultsBoth the success rate of surgery and the technical success rate of gallbladder polyp removal reached 100%， and of all eight patients， three patients used guide wire to enter the gallbladder under direct view， while five patients received oral cholangiopancreatography to directly enter the gallbladder. The time of operation was 51.88±12.34 minutes， and the time of gallbladder polyp removal was 23.13±10.94 minutes. The diameter of gallbladder polyp was 2‍ ‍—‍ ‍8 mm， and pathological examination showed inflammatory polyps in three patients， adenomatous polyps in one patient， and cholesterol polyps in four patients. There were no complications during or after surgery. The patients were followed up for 2‍ ‍—‍ ‍27 months after surgery， and no recurrence of gallbladder polyp was observed. ConclusionOral cholangiopancreatography is technically safe and feasible in endoscopic major duodenal papilla cholecystectomy.

Objective:To analyze the characteristics of obstructive sleep apnea（OSA）in children with Prader-Willi syndrome (PWS),and to improve the understanding of OSA during rapid eye movement sleep.Methods:The clinical data of 13 children with PWS aged 2-14 years admitted to Shenzhen Children's Hospital from June 2017 to June 2024 were retrospectively collected as the PWS group,and 12 children with snoring caused by adenoids,tonsil hypertrophy and/or obesity were selected as the control group.The gender,age,body mass index (BMI),obstructive apnea index (OAI),oxygen desaturation index (ODI),obstructive sleep apnea hypopnea index (OAHI),rapid eye movement period OAHI(OAHIrem),non-rapid eye movement period OAHI(OAHInrem) and OAHIrem/total sleep period OAHI ratio were compared between the two groups.Multivariate linear regression was used to assess the association between PWS and OAHIrem.Results:Among the 13 children in PWS group,there were 7 males and 6 females,with an average age of (7.63±4.05) years and an average BMI of (23.06±6.12) kg/m2.Among the 12 children in control group,there were 10 males and 2 females,with an average age of (7.28±3.92) years and an average BMI of (22.41±5.68) kg/m2.There were no statistically significant differences in age,gender,and BMI between the two groups ( P>0.05).All 13 children (100%) with PWS had OSA,with 8 cases (61.53%) of mild OSA and 5 cases (38.46%) of moderate to severe OSA.OAI and ODI in PWS group were significantly higher than those in control group ( P<0.05).OAHI and OAHInrem in PWS group were higher than those in control group,but the difference was not statistically significant ( P>0.05).OAHIrem and OAHIrem/ total sleep OAHI ratio were significantly higher than those in the control group,with statistical significance ( P<0.05).Multivariate linear regression analysis showed that PWS was significantly correlated with OAHIrem/ total sleep OAH ratio (square root) ( P=0.008). Conclusion:Children with PWS have a high incidence of OSA,with a high proportion of moderate to severe OSA.They are prone to OSA with hypoxemia during rapid eye movement sleep.It is recommended that respiratory monitoring of children with PWS during rapid eye movement sleep should be strengthened,and individualized treatment plan should be formulated according to the type and severity of OSA.

Acute respiratory distress syndrome(ARDS)is a common respiratory emergency,but current clinical treatment remains at the level of symptomatic support and there is a lack of effective targeted treatment measures.Our previous study confirmed that inhalation of hydrogen gas can reduce the acute lung injury of ARDS,but the application of hydrogen has flammable and explosive safety concerns.Drinking hydrogen-rich liquid or inhaling hydrogen gas has been shown to play an important role in scavenging reactive oxygen species and maintaining mitochondrial quality control balance,thus improving ARDS in patients and animal models.Coral calcium hydrogenation(CCH)is a new solid molecular hydrogen carrier prepared from coral calcium(CC).Whether and how CCH affects acute lung injury in ARDS re-mains unstudied.In this study,we observed the therapeutic effect of CCH on lipopolysaccharide(LPS)induced acute lung injury in ARDS mice.The survival rate of mice treated with CCH and hydrogen inhalation was found to be comparable,demonstrating a significant improvement compared to the untreated ARDS model group.CCH treatment significantly reduced pulmonary hemorrhage and edema,and improved pulmonary function and local microcirculation in ARDS mice.CCH promoted mitochon-drial peripheral division in the early course of ARDS by activating mitochondrial thioredoxin 2(Trx2),improved lung mitochondrial dysfunction induced by LPS,and reduced oxidative stress damage.The results indicate that CCH is a highly efficient hydrogen-rich agent that can attenuate acute lung injury of ARDS by improving the mitochondrial function through Trx2 activation.

Based on the theory of circulation of qi,a theoretical model of the circulation of phase fire in the human body was con-structed.It is proposed that cancer toxicity is the key factor that triggers the disorder of phase fire and hinders the circulation of phase fire.The disorder of phase fire and poor circulation are important pathogenesis of the occurrence and development of cancer toxicity.With the principle of strengthening healthy qi and eliminating evil qi,the Wenzi Jiedu method is used to treat tumors,which plays an important role in warming and nourishing,regulating yin and yang,and eliminating cancer toxicity.The combination of war-ming,nourishing and detoxification can promote the return of the phase fire and make the human body's generation and transformation active,providing a new treatment idea for TCM diagnosis and treatment of tumors with mainly cold poison or mixed cold and heat.

Acute respiratory distress syndrome (ARDS) is a common respiratory emergency, but current clinical treatment remains at the level of symptomatic support and there is a lack of effective targeted treatment measures. Our previous study confirmed that inhalation of hydrogen gas can reduce the acute lung injury of ARDS, but the application of hydrogen has flammable and explosive safety concerns. Drinking hydrogen-rich liquid or inhaling hydrogen gas has been shown to play an important role in scavenging reactive oxygen species and maintaining mitochondrial quality control balance, thus improving ARDS in patients and animal models. Coral calcium hydrogenation (CCH) is a new solid molecular hydrogen carrier prepared from coral calcium (CC). Whether and how CCH affects acute lung injury in ARDS remains unstudied. In this study, we observed the therapeutic effect of CCH on lipopolysaccharide (LPS) induced acute lung injury in ARDS mice. The survival rate of mice treated with CCH and hydrogen inhalation was found to be comparable, demonstrating a significant improvement compared to the untreated ARDS model group. CCH treatment significantly reduced pulmonary hemorrhage and edema, and improved pulmonary function and local microcirculation in ARDS mice. CCH promoted mitochondrial peripheral division in the early course of ARDS by activating mitochondrial thioredoxin 2 (Trx2), improved lung mitochondrial dysfunction induced by LPS, and reduced oxidative stress damage. The results indicate that CCH is a highly efficient hydrogen-rich agent that can attenuate acute lung injury of ARDS by improving the mitochondrial function through Trx2 activation.

Background::Atopic dermatitis (AD) is a chronic inflammatory skin disorder impacting populations worldwide, although its clinical characteristics and patient demographics remain uncharacterized in China. The aim of this study was to investigate the demographics, comorbidities, aggravating factors, and treatments in AD patients across different age groups in China.Methods::This cross-sectional study included Chinese AD patients from 205 hospitals spanning 30 provinces. Patients completed dermatologist-led surveys of general medical history, comorbidities, AD-related aggravating factors, and medications. Two-level mixed-ordered logistic regression was used to evaluate aggravating factors.Results::Overall, 16,838 respondents were included in the final analysis (aged 30.9 ± 24.1 years). The proportion of severe AD was the highest in patients with AD onset at ≥60 years (26.73%). Allergic rhinitis and hypertension were the most common atopic and metabolism-related non-atopic comorbidities, respectively. AD severity was significantly associated with chronic urticaria, food allergies, and diabetes. Aggravating factors including foods, seasonal changes, and psychological factors were also linked to AD severity. The cross-sectional survey implied that severe AD may be related to the undertreatment of effective systemic or topical interventions.Conclusion::To enhance the management of AD, it is crucial to consider both aggravating factors and the increased utilization of systemic immunotherapy.Registration::ClinicalTrials.gov, NCT05316805

Hemophilic arthritis(HA),caused by recurrent bleeding,can seriously affect patient quality of life and consumes extensive social and medical resources.There is thus a need to establish an animal model of HA for research;however,this is limited by ethical requirements.Here we review the recent literature and summarize research progress into animal models of HA at home and abroad,from the aspects of species selection,modeling method,histopathology,and imaging evaluation method.Species selection includes rodents such as mice,New Zealand rabbits,beagles,miniature pigs,and crab-eating macaques.Modeling method comprise gene knockout trauma models,gene knockout spontaneous models,and injection models.Among these,the gene knockout spontaneous model closely mimics the pathological process of spontaneous bleeding and concurrent arthritis in human HA,making it more relevant to human HA.However,due to high modeling costs,phenotypic instability,and low survival rates,this model is not the preferred choice for animal experimental studies.In contrast,gene knockout trauma models exhibit characteristics such as short modeling time,strong stability,and high success rates,thus being widely utilized in animal experimental research.Evaluation of HA models involves various imaging method including MRI,micro-CT,MSKUS/PD,in addition to various gross scoring method.By reviewing the progress of HA model research,more experimental evidence is provided for investigating the pathogenesis and validating the efficacy of HA treatments,thereby compensating for the lack of clinical data,particularly in the field of traditional Chinese medicine therapy.
