Bcakground: Pancreatic pseudocyst (PPC) is a common complication arising from acute or chronic pancreatitis, trauma, or pancreatic duct obstruction. When acute fluid collection persists for 4 - 6 weeks and is encapsulated by a fibrous wall, it is classified as a pancreatic pseudocyst. While PPC is generally asymptomatic in many patients, it can manifest with persistent abdominal pain, dyspepsia, intra-cystic infection, and potentially lead to gastrointestinal obstruction in some cases. Although smaller PPCs may resolve spontaneously, larger PPCs tend to be refractory to absorption and often necessitate surgical intervention to prevent complications such as intracystic hemorrhage. Objective: To explore the efficacy of percutaneous catheterization with negative pressure in the treatment of large pancreatic pseudocysts. Methods: The cases of large pancreatic pseudocysts treated in our hospital from 2004 to 2022 were retrospectively collected, and the general condition, operation time, drainage time, feeding time, postoperative complications, hospital stay, cost and follow-up of the patients were analyzed. Results: A total of 132 patients with large pancreatic pseudocysts were collected. The average operation time was 32.4 ± 2.1 min;The retention time of the drainage tube was 30 ± 1.8 days in the percutaneous negative pressure drainage group;The postoperative feeding time was no fasting after local anesthesia drainage;Postoperative complications (bleeding, infection, pancreatic leakage, recurrence, anastomotic leakage, etc.): Two of the 132 patients had recurrent cysts, which were cured by re-puncture and negative pressure drainage. The length of hospital stay was 6 ± 1.1 days;The cost was 11,200 ± 1300 yuan;Follow-up: The follow-up time ranged from 1 to 3 years, and the patients had no discomfort. Conclusion: Percutaneous catheterization and negative pressure drainage can effectively treat large pancreatic pseudocysts. Compared with other treatment methods, it is simple and effective, the postoperative recovery of patients is faster, the physical damage is less, the hospital stay is shorter, and the cost is lower. 展开更多

BACKGROUND Retroperitoneal liposarcoma(RPLS)is a rare malignant tumor initiated in adipocytes.It is discovered only when the tumor is large because of its deep anatomical location and insidious onset.Giant RPLS with a diameter exceeding 30 cm is extremely rare.Its diagnosis and treatment present extremely great challenges.CASE SUMMARY The patient,a 62-year-old woman,presented to the hospital complaining of abdominal distension for more than six months.Imaging examination revealed a large retroperitoneal mass.Finally,the patient was diagnosed with giant RPLS.The tumor occupied the entire abdominal cavity,severely compressed the abdominal organs,and adhered tightly to the bilateral ureters.After careful preoperative preparation(including three-dimensional visualization and bilateral ureteral stent implantation),we performed resection of the large retroperitoneal mass.The tumor was completely removed and consisted of multiple masses,with a total weight of 17 kg and the largest mass size of 35 cm×28 cm×14 cm.Postoperative pathological results revealed that the mass was a well-differentiated liposarcoma.The patient recovered well after surgery,and there was no sign of recurrence after 2 months of follow-up.CONCLUSION Surgical resection is the only radical treatment for giant RPLS.Preoperative preparation is essential,and three-dimensional visualization reconstruction is helpful for the formulation of surgical plans.Postoperative radiotherapy and neoadjuvant therapy can be reasonably selected,but whether they can reduce the recurrence rate is still controversial. 展开更多

As an endemic and critically-endangered wildlife species in China,the giant panda(Ailuropoda melanoleuca)has attracted widespread attention from all sectors of society regarding its survival status.In this study,the impact of earthquake-dameged areas on the distribution and activities of giant pandas in the Qionglai Mountains was analyzed by comparing data from two giant panda surveys conducted in the Qionglai Mountains of Sichuan Province and combining with remote sensing(RS)data from relevant regions.The results indicated that there was only a small area of overlap between the earthquake-damaged areas and giant panda activity trace points.The main earthquake-damaged areas were distributed at elevations(3,500-4,100 m)higher than the primary elevation range of giant panda distribution(1,700-3,100 m).In the Wolong Nature Reserve,no major earthquake damage was observed in the central section east of Provincial Highway 303 with relatively more giant panda activities.Within the Caopo Nature Reserve,the earthquake-damaged areas were mostly concentrated in the northeastern corner and along the border with the Wolong Nature Reserve.However,no large-scale giant panda activity traces were detected in these areas during either of the two surveys.Overall,the range of giant panda activities showed no signs of decline.Therefore,the impact of earthquakes on giant panda activities remains limited. 展开更多

BACKGROUND Choledochal cyst is a rare biliary tract disorder with five subtypes categorized based on the anatomical location of cystic dilatation.Type IV(which affects the intrahepatic and extrahepatic ducts)is the most common subtype in adults.Its clinical manifestations are diverse and the disease can potentially become malignant.Currently,the mainstay treatment is surgical excision which is used as a definitive treatment to prevent complications and avoid carcinogenesis.However,the surgical operation for giant choledochal cysts is technically challenging.CASE SUMMARY Here,we present a case of a giant choledochal cyst in an 18-year-old female.The diagnosis of patient was confirmed through magnetic resonance cholangiopancreatography.The patient developed acute cholangitis,and was treated with percutaneous transhepatic cholangial drainage to alleviate symptoms.The final treatment approach was cyst excision followed by Roux-en-Y hepaticojejunostomy,which successfully achieved excellent postoperative recovery.CONCLUSION Ultrasonography and magnetic resonance cholangiopancreatography can effectively diagnose choledochal cysts.Combined percutaneous transhepatic cholangial drainage surgery for giant choledochal cysts is safe and effective. 展开更多

BACKGROUND Hepatic hemangioma represents the most common benign primary hepatic neo-plasm.Although most such tumors are small and asymptomatic,giant cavernous hemangioma(GCH)is frequently symptomatic,and needs intervention.More-over,diffuse hepatic hemangiomatosis(DHH)is not rare in the liver parenchyma adjacent to a GCH.The management strategy for hepatic hemangiomas can differ depending on the presence of associated hemangiomatosis and the amount and distribution of the residual hepatic parenchyma.CASE SUMMARY Herein,we report two patients with GCH coexistent with DHH successfully treated by laparoscopic microwave ablation.The two GCHs were ablated com-pletely and the ablated zone atrophied obviously in imaging follow-ups after ablation.Surprisingly,there was a trend toward gradual reduction and dimini-shment of DHH.CONCLUSION Thermal ablation treatment might be an effective and less invasive treatment for GCH coexistent with DHH around the hemangioma. 展开更多

BACKGROUND Leiomyomas or fibroids commonly originate from the uterus;extrauterine leiomyomas are rare and most often arise from the broad ligament.Diagnosing broad ligament leiomyomas becomes particularly challenging when they undergo degenerative changes because their clinical and radiological features often mimic those of ovarian tumors.We report a rare case of a giant broad ligament fibroid with cystic degeneration,which was initially mistaken for an ovarian mass.CASE SUMMARY A 49-year-old woman presented with mild abdominal distension and pain as the only symptoms.Upon abdominal examination,a large mass measuring approximately 30 cm and extending from the pelvic cavity to just below the xiphoid process was identified.Both transvaginal ultrasound and contrast-enhanced computed tomography suggested an ovarian origin of the mass.However,laparotomy confirmed that the mass originated from the right broad ligament.The mass was separated from the uterus and bilateral ovaries,with no involvement of the uterus or ovaries.The mass was completely resected with respecting the patient’s desire to retain her uterus and adnexa.Postoperative histopathological examination confirmed leiomyoma with cystic degeneration.CONCLUSION Broad ligament myomas mimic ovarian tumors;accurate diagnosis and careful operation are critical to avoid complications and ensure safety. 展开更多

Type 2 diabetes(T2D)presents a significant health challenge,underscoring the need for functional foods and nutraceutical hypoglycemic bioactive peptides for its prevention.This study investigates the potential of proteolytic hydrolysate from artificially cultivated Chinese giant salamander(CGS)meat,a rich protein source,as a preventive strategy for T2D.We produced a CGS meat hydrolysate(CGSh)and demonstrated its ability to inhibit the T2D drug target dipeptidyl peptidaseⅣ(DPP-Ⅳ)through in vitro assays.We identified 5 peptides(WRPPDH,WAPPSKD,IPDSPF,IPEMIF,and VPIAVPT)with high DPP-Ⅳinhibitory activity in CGSh,suggesting its potential antidiabetic effects.In vivo experiments showed that CGSh effectively reduced insulin resistance in mice induced with a high-fat diet,as evidenced by a slower increase in blood glucose levels and a decreased HOMA-IR index.16S rRNA sequencing analysis revealed that CGSh improved gut microbial homeostasis,promoting beneficial microorganisms and reducing harmful bacteria.Metabolomic analyses identified an increase in valeric acid levels and highlighted nine potential biomarker metabolites.By inhibiting metabolic pathways such as AGE-RAGE,CGSh might also prevent diabetic complications and reduce inflammation.These findings suggest that CGSh has a promising hypoglycemic effect,making it a potential functional food ingredient for T2D prevention and treatment. 展开更多

BACKGROUND Giant coronary artery aneurysms(CAA),entailing thrombosis,myocardial infarction,and sudden death,are the most severe and life-threatening complications of Kawasaki disease(KD).Giant aneurysms rarely regress and can later transform into stenoses.Data on dynamic follow-up are scarce in the literature.AIM To evaluate clinical features and long-term outcomes of giant CAA in children with KD.METHODS A single-center retrospective study included data from patients with KD and giant CAA in the Irkutsk region(2012-2023).CAA criteria according to the American Heart Association guidelines of 2017 were used:(1)Dilated coronary artery with diameter Z-score>2 standard deviations(SD)but<2.5 SD;(2)Small CAA with Z-score>2.5 SD but<5 SD;(3)Medium CAA with Z-score>5 SD but<10 SD;and(4)Giant CAA with Z-score>10 SD or≥8 mm.RESULTS The mean age of children with coronary dilatation/aneurysms was 2.5 years,and the male-to-female ratio was 3:1.Patients with giant/medium CAA had symptoms of cerebral dysfunction more often compared with children with moderate(Z-score<5 SD but>2.0 SD)coronary dilatation(62.0%vs 21.0%,P=0.019).Major cardiovascular events(myocardial infarction,coronary artery bypass grafting,acute coronary syndrome,ischemic cardiomyopathy,left ventricular aneurysm,and giant extracardiac aneurysm)occurred in 55.5%of patients who had giant CAA.At follow-up the complete regression of giant/medium CAA was observed in 58.0%and partial regression in 42.0%after a mean of 2.3 and 5.5 years,respectively.All thrombi detected by echocardiography,CT,and angiography in giant/medium CAA disappeared between 1 year and 5 years(mean:15 months).All patients survived.CONCLUSION Risk factors for giant CAA were male sex,early age,and cerebral dysfunction.Complete regression of giant coronary aneurysms occurred in 58.0%of patients after follow-up of 2.3 years. 展开更多

We study single photon scattering in a one-dimensional coupled resonator waveguide,which is dressed by a small and a giant artificial atom simultaneously.Here,we have set the small atom to be a neighbor to one leg of the giant atom,and the giant atom couples to the waveguide via two distant sites.When the small and giant atoms are both resonant with the bare resonator in the waveguide,we observe the perfect reflection of the resonant incident photon.On the other hand,when the small atom is detuned from the giant atom,the single photon reflection is characterized by a wide window and Fano line shape.We hope our work will pave the way for the potential application of small and giant atom hybrid systems in the study of photonic control in the lowdimensional waveguide structure. 展开更多

The giant triton snail Charonia tritonis is a marine large carnivorous gastropoda inhabiting in the Indo-Pacific Ocean.Their splendid and highly organized Charonia tritonis shells are attractive;however few studies have been conducted on shell ultra-structure and pigmentation.The arrangements of crossed-lamellar structures were distinctive for the giant triton snail shell,showing three layers of mineral structures in the cross-section.The 1st-order and 2nd-order lamellae of the shell were around 10-20μm and the crystals in outer layers intersected at right angles in this species.They were identified as aragonite crystals by Raman scattering,and granular organic matrix were attached to the aragonite mineral phase closely.Furthermore,the dominant Raman spectra from polyene pigments in the shell were characterized at wavenumbers of 1123 cm^(-1)and 1504 cm^(-1),assigned to stretching vibrations of carbon-carbon single(C-C)and double(C=C)bonds,and the polyene chain was confirmed with 11-12 C-C bonds and 12-13 conju-gated C=C bonds.The research will lay a foundation for exploring the relationship between the calcareous shell and the formation of shell color in the giant triton snail. 展开更多

BACKGROUND Giant cell tumor of bone(GCTB)is a rare,locally aggressive neoplasm that should be treated surgically,whenever possible.This treatment approach may be linked with greater morbidity besides functional impairment.Denosumab is a human monoclonal antibody.Its administration inhibits bone resorption and has become part of the therapeutic armamentarium against GCTB,as it allows local control with a view to downstaging for a more conservative surgical procedure.However,there is no consensus in the literature regarding the optimal denosumab regimen for GCTB.Therefore,a wide discussion of denosumab regimen is necessary.AIM To assess the effectiveness of various therapy protocols employing denosumab in individuals with GCTB.METHODS A broad and systematic literature search was carried out using the PRISMA guidelines.We analyzed studies that reported skeletally mature patients with GCTB regardless of sex or ethnicity treated with denosumab.Articles with fewer than five patients and in languages except Spanish,Portuguese and English were excluded.Statistical analysis with proportion meta-analysis was performed due to the dichotomous nature of the data.RESULTS 1005 articles were screened,of which 26 articles met the inclusion criteria and were selected,totaling 1742 patients,51.8%women and 48.2%men,with an average of 35 years of age.Treatment with denosumab was associated with high rates of clinical benefit(CB)and imaging response(IR),without changing local recurrence rates when compared to patients treated without denosumab,regardless of the therapeutic regimen adopted and the number of doses applied.The adverse events(AE)presented were mostly mild,with the exception of a malignant transformation to osteosarcoma.CONCLUSION Treatment of GCTB with denosumab is effective,showing high rates of CB and IR.The AE that occurred were mostly mild.We found no differences between the articles considering the researched outcomes regardless of the therapeutic regimen adopted. 展开更多

Maintaining high piezoelectric response and piezoelectric temperature stability of lead-based piezoceramics is critical for applications under high-temperature environments.Unfortunately,the piezoelectric response of lead-based piezoceramics shows strong temperature dependence.Herein,an innovative strategy was proposed to solve this problem.The method consisted of constructing“slush-like”polar states by introducing localized heterostructures in the tetragonal phase structure to lower the energy barriers.The presence of the tetragonal phase stabilized the domain structure,providing excellent temperature stability,while the localized heterostructures also flattened the free energy landscape and enhanced the piezo-electric response.The strategy was implemented by using 0.11Pb(In_(0.5)Nb_(0.5))O_(3)-0.89Pb(Hf_(0.47)Ti_(0.53))O_(3)(PIN-PHT)piezoceramics doped with heterovalent ion Nb^(5+)to form a“slush-like”polar state with strong in-teractions inside the ceramics.The piezoelectric response and relaxor behavior of the ceramics were then investigated using piezoelectric force microscopy to reveal the mapping relationship between the complex ferroelectric domain structure and both the piezoelectric response and temperature stability.At Nb5+doping amount of 0.8 mol%,the ceramics showed excellent comprehensive performances with d_(33)=764 pC/N,T_(c)=319.1℃,ε_(r)=3253.59,k_(p)=0.67,and tan δ=0.0122.At an external ambient temperature of 300℃,the d_(33) of PIN-PHT-0.8Nb^(5+) remained high at 734 pC/N,with piezoelectric performance retention of 96.1%,showing excellent temperature stability.Overall,a new path was proposed for developing Pb-based piezoceramics with both good piezoelectric response and high-temperature stability,promising to broaden the temperature range of high-temperature piezoceramics for various applications. 展开更多

BACKGROUND Hepatic manifestations in chronic lymphocytic leukemia(CLL)are common:Elevation of liver enzymes frequently occurs,and differential diagnosis is often challenging.Liver infiltration by leukemic cells,primary and secondary hepatic malignancies,drug-induced hepatotoxicity,immunological disorders,and infections have been reported.Nevertheless,syncytial giant cell hepatitis(GCH)as a manifestation of autoimmune hepatitis in patients with CLL is an extremely rare condition,currently reported only in anecdotal cases.CASE SUMMARY Here,we report the case of a 62-year-old Caucasian woman affected by CLL,who developed GCH with peculiar histopathological features.The patient was evaluated for abnormal liver test results.Liver histology revealed significant inflammatory lymphomononuclear infiltrates with a plasma cell component,widespread syncytial changes in the hepatocytes with gigantocellular features,hepatocyte rosettes,and the typical feature of emperipolesis,consistent with a diagnosis of GCH.The patient was treated with corticosteroids and mycophenolate mofetil,resulting in a complete biochemical response.CONCLUSION Early histological diagnosis of GCH is crucial in patients with CLL,with mycophenolate mofetil representing a promising treatment option. 展开更多

Magnon spin currents in insulating magnets are useful for low-power spintronics. However, in magnets stacked by antiferromagnetic(AFM) exchange coupling, which have recently aroused significant interest for potential applications in spintronics, Bose–Einstein distribution populates magnon states across all energies from opposite eigenmodes, and hence the magnon spin current is largely compensated. Contrary to this common observation,here, we show that magnets with X-type AFM stacking, where opposite magnetic sublattices form orthogonal intersecting chains, support giant magnon spin currents with minimal compensation. Our model Hamiltonian calculations predict magnetic chain locking of magnon spin currents in these X-type magnets, significantly reducing their compensation ratio. In addition, the one-dimensional nature of the chain-like magnetic sublattices enhances magnon spin conductivities surpassing those of two-dimensional ferromagnets and canonical altermagnets. Notably, uncompensated X-type magnets, such as odd-layer antiferromagnets and ferrimagnets, can exhibit magnon spin currents polarized opposite to those expected by their net magnetization. These unprecedented properties of X-type magnets, combined with their inherent advantages resulting from AFM coupling, offer a promising new path for low-power high-performance spintronics. 展开更多

The two-dimensional electron gas(2DEG)formed at the interface between two oxide insulators provides new opportunities for electronics and spintronics.The broken inversion symmetry at the heterointerface results in a Rashba spin-orbit coupling(RSOC)effect that enables the conversion between spin and charge currents.However,conducting oxide interfaces that simultaneously exhibit strong RSOC and high carrier mobility-a combination query for achieving high spin-to-charge inter-conversion efficiencies-remain scarce.Herein,we report a correlated 2DEG with giant Rashba splitting and high electron mobility in(111)-oriented EuTiO_(3)/KTaO_(3)(ETO/KTO)heterostructures under light illumination.Upon light modulation,a unique carrier-dependent giant anomalous Hall effect,the signature of spin-polarized 2DEG,emerges with a sign crossover at a carrier density of approximately 5.0×10^(13)cm^(-2),highlighting dramatic changes in the band topology of KTO(111)interface.Furthermore,at 2 K,the carrier mobility is enhanced from 103 cm^(2)·V^(-1)·s^(-1)to 1800 cm^(2)·V^(-1)·s^(-1),a remarkable enhancement of approximately 20 times.Accompanying with a giant Rashba coefficient αR up to 360meV·˚A,this high mobility ferromagnetic 5d oxide 2DEG is predicted to achieve a giant spin-to-charge conversion efficiency ofλ~10 nm,showing great potential for designing low-power spin-orbitronic devices. 展开更多

Recent advances in two-dimensional layered systems have greatly enriched electronic transport studies, particularly in inter-layer Coulomb drag research. Here, systematic transport measurements were conducted in graphene-based electronic double-layer structures, revealing giant yet reproducible drag fluctuations at cryogenic temperatures. These fluctuations' characteristics, including amplitude and peak/valley spacing, are mainly determined by the drag layer's carrier dynamics rather than the drive layer's, resulting in violation of the Onsager reciprocity relation. Notably, the drag fluctuations remain observable up to 35 K, far exceeding universal conductance fluctuations within individual layers. This suggests enhanced phase coherence in inter-layer drag compared to single-layer transport, as further confirmed by quantitative analysis of auto-correlation fields of fluctuations under magnetic fields. Our findings provide new insights into quantum interference effects and their interplay with Coulomb interactions in solids. The observations of significant drag fluctuations could potentially help address chaotic signals between nearby components in nanoscale devices. 展开更多
