BACKGROUND Hemorrhage associated with varices at the site of choledochojejunostomy is an unusual,difficult to treat,and often fatal manifestation of portal hypertension.So far,no treatment guidelines have been established.CASE SUMMARY We reported three patients with jejunal varices at the site of choledochojejun-ostomy managed by endoscopic sclerotherapy with lauromacrogol/α-butyl cyanoacrylate injection at our institution between June 2021 and August 2023.We reviewed all patient records,clinical presentation,endoscopic findings and treatment,outcomes and follow-up.Three patients who underwent pancre-aticoduodenectomy with a Whipple anastomosis were examined using conven-tional upper gastrointestinal endoscopy for suspected hemorrhage from the afferent jejunal loop.Varices with stigmata of recent hemorrhage or active he-morrhage were observed around the choledochojejunostomy site in all three patients.Endoscopic injection of lauromacrogol/α-butyl cyanoacrylate was carried out at jejunal varices for all three patients.The bleeding ceased and patency was observed for 26 and 2 months in two patients.In one patient with multiorgan failure and internal environment disturbance,rebleeding occurred 1 month after endoscopic sclerotherapy,and despite a second endoscopic sclero-therapy,repeated episodes of bleeding and multiorgan failure resulted in eventual death.CONCLUSION We conclude that endoscopic sclerotherapy with lauromacrogol/α-butyl cyanoac-rylate injection can be an easy,effective,safe and low-cost treatment option for jejunal varicose bleeding at the site of choledochojejunostomy.

Developing highly sensitive optical thermometers is of great significance due to their capability to enable remote and non-contact temperature measurements, rendering them highly applicable in diverse and harsh environments. Herein we report a temperature-dependent phosphor of 0D metal halide hybrid by incorporating Bi3+into the（MePPh3）2ZnCl4matrix. Through Bi3+doping,the initially non-luminescent（MePPh3）2ZnCl4matrix exhibits a deep-blue emission centered at 453 nm, with a photoluminescence quantum yield（PLQY） of 5.71% and a Stokes shift of 75 nm at room temperature. Experimental characterization demonstrates that exciton-like luminescence of Bi3+is mainly responsible for the blue emission. Single crystals of Bi3+-doped（MePPh3）2ZnCl4show an unusual correlation between photoluminescence（PL） lifetime and temperature. Particularly, the dependence of luminescence lifetime on temperature is most remarkable in the temperature range of 80 to 100 K with an exceptional sensitivity up to 0.09 K-1, representing one of the best levels for thermometry based on PL decay lifetime. Our work not only provides a viable strategy for designing a novel, environmentally friendly, and stable blue emitter, but also paves the way for precise thermometric application at low temperature.

Background Anti-leucine-rich glioma-inactivated 1(LGI-1)autoimmune encephalitis(AE),characterized by rapid decline of memory,seizures,and neuropsychiatric abnormalities,is a rare but devastating disorder.Early diagnosis and treatment are essential to prevent long-term sequelae.In this report,we provide a detailed description of clinical characteristics,laboratory test results,imaging,and electroencephalography(EEG)findings,as well as treatment responses of eight patients with anti-LGI-1 AE treated at our center.Case presentation At the onset,all eight patients presented with confusion/memory deterioration,seizures(including faciobrachial dystonic seizures or other types of seizure),and behavioral changes such as hallucination,paranoia,and anxiety.Four patients were found with severe hyponatremia.Anti-LGI1 antibodies were detected in the cerebrospinal fluid and/or serum of all patients.For patients with faciobrachial dystonic seizures,no discernible scalp EEG change was detected,while EEG recording of patients experiencing other types of seizure showed focal slowing,focal epileptiform discharges,and focal onset seizures.All patients showed abnormal brain magnetic resonance imaging signals,mainly involving the mesial temporal lobe and the hippocampus.In addition,one patient also experienced fulminant cerebral edema during the acute phase of the illness.All patients received immunotherapy and anti-seizure medications and achieved good seizure control.Nevertheless,these patients continued to experience cognitive impairment during their long-term follow-ups.Conclusions The care of anti-LGI1 AE patients requires rapid evaluation,prompt initiation of immunotherapy,and long-term follow-up.The long-term presence of neurocognitive complications observed in these patients underline the importance of developing reliable biomarkers that can distinguish between different subtypes of this disease with heterogeneous clinico-electrographico-radiological features.Further research is needed to understand the molecular mechanisms un

On September 5, 2022, a magnitude Ms 6.8 earthquake occurred along the Moxi fault in the southern part of the Xianshuihe fault zone located in the southeastern margin of the Tibetan Plateau,resulting in severe damage and substantial economic loss. In this study, we established a coseismic landslide database triggered by Luding Ms 6.8 earthquake, which includes 4794 landslides with a total area of 46.79 km^(2). The coseismic landslides primarily consisted of medium and small-sized landslides, characterized by shallow surface sliding. Some exhibited characteristics of high-position initiation resulted in the obstruction or partial obstruction of rivers, leading to the formation of dammed lakes. Our research found that the coseismic landslides were predominantly observed on slopes ranging from 30° to 50°, occurring at between 1000 m and 2500 m, with slope aspects varying from 90° to 180°. Landslides were also highly developed in granitic bodies that had experienced structural fracturing and strong-tomoderate weathering. Coseismic landslides concentrated within a 6 km range on both sides of the Xianshuihe and Daduhe fault zones. The area and number of coseismic landslides exhibited a negative correlation with the distance to fault lines, road networks, and river systems, as they were influenced by fault activity, road excavation, and river erosion. The coseismic landslides were mainly distributed in the southeastern region of the epicenter, exhibiting relatively concentrated patterns within the IX-degree zones such as Moxi Town, Wandong River basin, Detuo Town to Wanggangping Township. Our research findings provide important data on the coseismic landslides triggered by the Luding Ms 6.8 earthquake and reveal the spatial distribution patterns of these landslides. These findings can serve as important references for risk mitigation, reconstruction planning, and regional earthquake disaster research in the earthquake-affected area.

Background Various cardiac and autonomic manifestations are frequently reported during seizures.Among the seizure-related arrhythmia,ictal tachycardia is the most common,followed by ictal bradycardia,with ictal asystole being the rarest.The occurrence of ictal asystole may obscure the clinical presentation and delay the diagnosis,representing a life-threatening presentation of epilepsy,with an elevated risk of sudden unexpected death in epilepsy patients(SUDEP).These cardiac abnormalities are being increasingly recognized as the key to elucidating the mechanisms of SUDEP.Case presentation We present a 35-year-old man with a history of focal-onset seizures with impaired consciousness since his mid-20 s.He developed different types of seizures for 2 years,described as tonic seizure and atonic seizure(drop attack).During such clinical events,he suffered from falls and cardiac arrest.However,thorough cardiac electrophysiology and imaging workup failed to reveal a cardiac etiology.Subsequent video electroencephalograph(EEG)monitoring was performed,and ictal bradycardia and ictal asystole were discovered.A cardiac pacemaker was implanted,and at 3-year follow-up,the patient did not suffer more atonic seizures,or falls.Genetic tests discovered a de novo variant of Adhesion G Protein-Coupled Receptor V1(ADGRV1),which may provide a clue for the patient’s ictal asystole and the increased risk of SUDEP.Conclusions Considering the important impact of ictal bradycardia and asystole on the morbidity and potential mortality of epileptic patients,it is important to simultaneously utilize EEG and electrocardiogram to confirm the diagnosis.This case report highlights the link between the de novo variant of ADGRV1 and the ictal bradycardia/asystole phenotype and implicates the importance of genetic testing in adult epilepsy patients.

The effect of tempering on carbides and hydrogen embrittlement in E690 high strength marine structural steel has been investigated.The steel was tempered at 600℃ for 1–3 h.Detailed characterization was carried out to characterize the microstructure,especially the dislocation density and grain size.The hydrogen permeation test and thermal desorption spectroscopy test were also implemented.The dislocation density decreases,the amount of carbide increases,and carbides(M_(23)C_(6) and MX)coarsen with the tempering time increasing.After tempered at 600℃ for 3 h,the diffusible hydrogen trapped by lattice and dislocation decreases while the non-diffusible hydrogen trapped by carbides increases,leading to the best hydrogen embrittlement resistance,although hydrogen diffuses rapidly due to the reduction of dislocation density.And the fracture mode changes from a combination of brittle cleavage and ductile dimpled fracture to fully ductile dimple fracture under hydrogen charging condition.Moreover,a phenomenon that hydrogen accelerates the dislocations movement of the steel during deformation was observed,which is related to the fact that hydrogen enhanced localized plasticity mechanism.

The crystallographic features of pearlite were investigated by experiments and edge-to-edge matching principle. Two new orientation relationships between ferrite and cementite were determinated by selected area electron diffraction and then explained by our modified edge-to-edge matching method. The consistence of the experimental results with theoretical prediction confirms the practicability of the modified edge-to-edge matching model.
