Sulfurized polyacrylonitrile(SPAN)is proposed as a promising cathode material for lithium sulfur batteries.However,the continuous side reactions at the electrolyte-electrode interfaces as well as the slow redox kinetics of SPAN cathode deteriorate the electrochemical performance.In this study,an electrolyte with dual-additives comprising 2-fluoropyridine(2-FP)and lithium difluorobis(oxalato)phosphate(liDFBOP)was used to improve the performance of li||SPAN cells.2-FP has a lower lowest occupied molecular orbital energy than that of the solvents in the electrolyte,leading to its prior reduction.A liF-rich film can be formed on the electrode,effectively improving the stability of the electrolyte-electrode interfaces and prolonging the life.Simultaneously,liDFBOP could form an electrolyte-electrode interface film containing a large amount of li_(x)PO_(y)F_(z) species,compensating for the kinetic deterioration caused by the lower ionic conductive of liF formed at the electrolyte-electrode interface.Hence,an electrode-interface film with good chemical stability and high li^(+) transport was established by liF and li_(x)PO_(y)F_(z)-rich species.The li||SPAN cell with the electrolyte containing dual-additives demonstrates an excellent capacity retention of 97.5%after 200 cycles at 1.0 C,25℃,comparing to 56.2%capacity retention without additives.Moreover,the rate capacities of cells with dual-additives can reach 1128.1 mAh/g at 5 C,comparing to only 813.5 mAh/g using electrolyte without additives.Our results shown that the dual-additives in electrolyte provide a promising strategy for practical application of lithium sulfur batteries with SPAN cathodes.

Observations and models indicate that human activities exert a considerable impact on the frequency and intensity of extreme temperature events,which are associated with global warming.However,changes in the duration of extreme temperature events and their association with human influence have not been considered in most studies.Thus,the possible relationship between the observed changes in the warm and cold spell duration(WSDI and CSDI)in hotspot regions during 1960-2014 and human influence was investigated based on the NCEP/NCAR reanalysis version 1 and Coupled Model Inter-comparison Project Phase 6(CMIP6)data.Constraint projection based on these attribution results was also performed.The optimal fingerprinting technique was used to compare observed changes in WSDI and CSDI to simulated changes averaged across eight CMIP6 models.Results show that anthropogenic(ANT)forcing contributed to the observed increase in WSDI in the three hotspot regions(West Asia,South Asia and Southeast Asia),with the majority of the changes being attributed to greenhouse gas forcing.However,a generally weak ANT signal can be observed in the decreasing trend of CSDI and can be detected in South and Southeast Asia.The influence of aerosol forcing remains undetected in either WSDI or CSDI,which differs from the results for frequency and intensity of extreme temperatures.The attribution results revealed that the constrained projection of WSDI is lower than the raw projection for 2015-2100 in West Asia and Southeast Asia.However,no differences in future CSDI changes are found in Southeast Asia between the constrained and raw projections.

Hypertriglyceridemia is the third leading cause of acute pancreatitis(AP),and its incidence is increasing.Due to its relatively insidious etiology,it is easy to be ignored in the early stages.In China,Chaiqin Chengqi Decoction(CQCQD)has long been employed for treating AP.AIM To evaluate the effectiveness of CQCQD in patients diagnosed with mild/moderately severe hypertriglyceridemic AP(HTG-AP).METHODS In this study,the clinical data of 39 patients with HTG-AP admitted from January 2019 to November 2022 were collected.The changes of blood lipids,gastrointestinal symptoms,and abdominal pain before and after treatment were analyzed and compared between the two groups.RESULTS Twenty patients were treated with the conventional HTG-AP regimen,and 19 patients were additionally treated with CQCQD.After receiving treatment,the triglycerides(TG)level of the CQCQD group was lower than that of the CQCQD group(3.14±0.25 mmol/L vs 4.96±0.47 mmol/L,P<0.01).After 3 d of treatment,the patients in the CQCQD group had more bowel movements than the control group(2.51±0.25 times vs 1.00±0.17 times,P=0.01).The gastrointestinal function of most patients returned to normal,and the acute gastrointestinal injury score was significantly lower than that of the control group(0.11±0.07 vs 0.42±0.11,P<0.01).CONCLUSION In patients with HTG-AP,CQCQD can significantly reduce the TG level,shorten the recovery time of defecation,significantly improve the gastrointestinal function.

The integrity of retinal ganglion cells is tightly associated with diabetic macular degeneration that leads to damage and death of retinal ganglion cells,affecting vision.The major clinical treatments for diabetic macular edema are anti-vascular endothelial growth factor drugs and laser photocoagulation.However,although the macular thickness can be normalized with each of these two therapies used alone,the vision does not improve in many patients.This might result from the incomplete recovery of retinal ganglion cell injury.Therefore,a prospective,non-randomized,controlled clinical trial was designed to investigate the effect of anti-vascular endothelial growth factor drugs combined with laser photocoagulation on the integrity of retinal ganglion cells in patients with diabetic macular edema and its relationship with vision recovery.In this trial,150 patients with diabetic macular edema will be equally divided into three groups according to therapeutic methods,followed by treatment with anti-vascular endothelial growth factor drugs,laser photocoagulation therapy,and their combination.All patients will be followed up for 12 months.The primary outcome measure is retinal ganglion cell-inner plexiform layer thickness at 12 months after treatment.The secondary outcome measures include retinal ganglion cell-inner plexiform layer thickness before and 1,3,6,and 9 months after treatment,retinal nerve fiber layer thickness,best-corrected visual acuity,macular area thickness,and choroidal thickness before and 1,3,6,9,and 12 months after treatment.Safety measure is the incidence of adverse events at 1,3,6,9,and 12 months after treatment.The study protocol hopes to validate the better efficacy and safety of the combined treatment in patients with diabetic macula compared with the other two monotherapies alone during the 12-month follow-up period.The trial is designed to focus on clarifying the time-effect relationship between imaging measures related to the integrity of retinal ganglion cells and best-corrected visual acuity.

A vortex-induced vibration(VIV)experiment of rough risers with coupling interference effect under a side-by-side arrangement was carried out in a wave-current combined flume.The roughness of the riser was characterized by arranging different specifications of surface attachments on the surface of the riser.Rough risers with three different roughnesses were arranged side by side with smooth risers to explore the VIV response of the riser under the combined action of roughness and interference effect,and to reveal the coupling mechanism between roughness and interference effect.The experimental results show that,compared with that of a smooth riser,the VIV of a rough riser under the coupling interference effect has a wider"lock-in"region,and the displacement decreases more significantly at a high reduced velocity,which is more likely to excite higher-order modes and frequency responses.In addition,the displacement response and frequency response of the smooth riser are not significantly affected by wake interference from the rough riser,which is caused by the decrease of the wake region due to the delay of the boundary layer separation point of the rough riser.

Inulin-type fructan CP-A,a predominant polysaccharide in Codonopsis pilosula,demonstrates regulatory effects on immune activity and anti-inflammation.The efficacy of CP-A in treating ulcerative colitis(UC)is,however,not well-established.This study employed an in vitro lipopolysaccharide(LPS)-induced colonic epithelial cell model(NCM460)and an in vivo dextran sulfate sodium(DSS)-induced colitis mouse model to explore CP-A’s protective effects against experimental colitis and its underlying mechanisms.We monitored the clinical symptoms in mice using various parameters:body weight,disease activity index(DAI),colon length,spleen weight,and histopathological scores.Additionally,molecular markers were assessed through enzyme-linked immunosorbent assay(EliSA),quantitative real-time polymerase chain reaction(qRT-PCR),immunofluorescence(IF),immunohistochemistry(IHC),and Western blotting assays.Results showed that CP-A significantly reduced reactive oxygen species(ROS),tumor necrosis factor-alpha(TNF-α),and interleukins(IL-6,IL-1β,IL-18)in LPS-induced cells while increasing IL-4 and IL-10 levels and enhancing the expression of Claudin-1,ZO-1,and occludin proteins in NCM460 cells.Correspondingly,in vivo findings revealed that CPA administration markedly improved DAI,reduced colon shortening,and decreased the production of myeloperoxidase(MPO),malondialdehyde(MDA),ROS,IL-1β,IL-18,and NOD-like receptor protein 3(NLRP3)inflammasome-associated genes/proteins in UC mice.CP-A treatment also elevated glutathione(GSH)and superoxide dismutase(SOD)levels,stimulated autophagy(LC3B,P62,Beclin-1,and ATG5),and reinforced Claudin-1 and ZO-1 expression,thereby aiding in intestinal epithelial barrier repair in colitis mice.Notably,the inhibition of autophagy via chloroquine(CQ)diminished CP-A’s protective impact against colitis in vivo.These findings elucidate that CP-A’s therapeutic effect on experimental colitis possibly involves mitigating intestinal inflammation through autophagymediated NLRP3 inflammasome inactivation.Consequently,inul
