Objective To investigate the relationship between daily intake of monounsaturated fatty acids(MUFAs)and polyunsaturated fatty acids(PUFAs)and non-alcoholic fatty liver disease(NAFLD),and to determine the threshold values of daily MUFAs and PUFAs intake for NAFLD risk.Methods Date were collected from the Dryad database.We enrolled a total of 1 068 healthy subjects aged 18 years and older(534 in the control group and 534 with NAFLD group)who had physical check-up in the Affiliated Nanping First Hospital of Fujian Medical University from April 2015 to August 2017.Comprehensive medical histories were obtained through questionnaires;information on dietary intake was collected using a semi-quantitative food frequency questionnaire and daily MUFAs and PUFAs intake were calculated.Baseline characteristics were compared between the two groups,and Logistic regression and restricted cubic spline(RCS)analyses were used to explore the relationship between daily MUFAs or PUFAs intake and NAFLD.Results Compared with the control group,the prevalence of hypertension,tea drinking,body mass index(BMI),daily energy intake,and daily MUFAs and PUFAs intakes were significant higher in patients with NAFLD(all P＜0.05),but the proportion of physical activities was significantly lower(P＜0.05).Logistic regression analysis revealed that after adjusting other confounding factors such as age,gender and BMI,for every 10 g increase in daily MUFAs or PUFAs intake,the risk of NAFLD increased by 53％(95％ CI:1.25-1.87,P＜0.001)and 3.30 times(95％ CI:2.98-6.20,P＜0.001),respectively.RCS indicated an approximately linear relationship between daily MUFAs intake and NAFLD(P for nonlinearity=0.064)and a nonlinear relationship between daily PUFAs intake and NAFLD(P for nonlinearity＜0.05).Subgroup analysis results were generally consistent,and there was statistical evidence of interactions between MUFAs and factors such as gender,hypertension and education level,with interaction between PUFAs and BMI observed(P＜0.05).Conclusion Increased daily intake of MUFAs or PUFAs is significantly associated with an increased risk of NAFLD,and further research is needed to clarify their specific roles in hepatic lipid accumulation.

Objective To investigate the association between plasma atherogenic index of plasma(AIP)and metabolism-associated steatotic liver disease(MASLD),and to evaluate the potential value of AIP as a predictive marker for MASLD risk.Methods We enrolled a total of 4 850 health check-up participants from The Second Affiliated Hospital of Xi'an Jiaotong University between June 2021 and May 2023.The participants were divided into quartiles(Q1-Q4)according to their AIP level.Biochemical indicators and MASLD prevalence were compared across groups.Logistic regression,subgroup analysis,and restricted cubic splines(RCS)were used to explore the relationship between AIP and MASLD.Results Among the 4 850 participants,the prevalence of MASLD was 26.08％(1 265/4 850).MASLD prevalence increased across AIP quartiles:4.0％,13.8％,30.8％,and 55.6％in Q1-Q4,respectively(P＜0.001).Compared with Q1,Q2-Q4 groups showed higher proportions of males,BMI,smokers,overweight/obesity,central obesity,prediabetes,hypertension,serum uric acid,and fatty liver index(FLI)(all P＜0.001).Lipid profiles worsened with increased AIP:total cholesterol,triglycerides,and LDL-C increased,while HDL-C decreased(P＜0.001).RCS analysis demonstrated a significant linear relationship between AIP and MASLD risk.After adjusting for confounders,the participants in Q4 had an 8.71-fold higher risk of MASLD than those in Q1(OR:8.71,95％CI:6.20-12.23,P＜0.001).A composite model incorporating AIP,BMI,and FLI showed superior discriminative performance(AUC:0.883,95％CI:0.873-0.892).Interaction analysis suggested that AIP had significant interactions with BMI,hypertension,and prediabetes(P＜0.05).In individuals without these metabolic abnormalities,the association between AIP and MASLD was more pronounced.Conclusion Elevated AIP was significantly associated with an increased risk of MASLD,with a stronger association observed in individuals with normal BMI,blood pressure,and blood glucose levels,suggesting that AIP may serve as a potential indicator for early screening of MASLD.

Objective:To identify the genetic mutation of coagulation factor Ⅶ(F7)gene in a pedigree with coagulation factor Ⅶ(FⅦ)deficiency and explore the molecular pathogenesis.Methods:The prothrombin time(PT),activated partial thromboplastin time(APTT),thrombin time(TT),D-dimer(DD),fibrin degradation products(FDP)and coagulation factor Ⅶ activity(FⅧ:C)of the proband and her family members were detected by Sysmex-CS5100 analyzer.All exons and exon-intron boundaries of the F7 gene were amplified by PCR followed by direct sequencing.The detected mutation was confirmed by reverse sequencing.The ClustalW software was used to analyze the conservatism of the mutant site.Pathogenicity of the mutation was assessed with Mutation Taster and PolyPhen-2 online bioinformatics software.Structure of the mutant protein was analyzed using Swiss-PdbViewer software.Results:The results of routine coagulation tests showed that PT of the proband was markedly extended to 42.5 s,and her FⅦ:C significantly reduced to 2％.The FⅦ:C of her grandmother,mother and sister had slightly reduced to 49％,51％,and 42％,respectively.These coagulant parameters of her father were within the normal range.Genetic analysis reveled a heterozygous G＞A change at cDNA 646 in exon 6 of F7 gene in the proband,resulting in a replacement of glycine at 156 of FⅦ catalytic region with serine(p.Gly156Ser).The sequencing results of other exons and exon-intron boundaries of her F7 gene were normal.The proband's grandmother,mother and sister were all the carriers of this missense mutation except her father.Bioinformatics analysis showed that the p.Gly156Ser mutation caused polarity change of the amino acid at this site and formation of side chains,leading to increase of protein instability,which may affect catalytic activity of structural domain.Meanwhile,both Mutation Taster and PolyPhen-2 online bioinformatics software also predicted the pathogenicity of this missense mutation with high scores.Conclusion:The heterozygous p.Gly 156Ser mutation is the direct cause of the reduced FⅦ in this proband.

Objective To monitor the antifungal resistance of clinical isolates of Candida spp.in the East China region.Methods MALDI-TOF MS or molecular methods were used to re-identify the strains collected from January 2018 to December 2022.Antifungal susceptibility testing was performed using the broth microdilution method.The susceptibility test results were interpreted according to the breakpoints of 2022 Clinical and Laboratory Standards Institute(CLSI)documents M27 M44s-Ed3 and M57s-Ed4.Results A total of 3 026 strains of Candida were collected,65.33％of which were isolated from sterile body sites,mainly from blood(38.86％)and pleural effusion/ascites(10.21％).The predominant species of Candida were Candida albicans(44.51％),followed by Candida parapsilosis complex(19.46％),Candida tropicalis(13.98％),Candida glabrata(10.34％),and other Candida species(0.79％).Candida albicans showed overall high susceptibility rates to the 10 antifungal drugs tested(the lowest rate being 93.62％).Only 2.97％of the strains showed dose-dependent susceptibility(SDD)to fluconazole.Candida parapsilosis complex had a SDD rate of 2.61％and a resistance rate of 9.42％to fluconazole,and susceptibility rates above 90％to other drugs.Candida glabrata had a SDD rate of 92.01％and a resistance rate of 7.99％to fluconazole,resistance rates of 32.27％and 48.24％to posaconazole and voriconazole non-wild-type strains(NWT),respectively,and susceptibility rates above 90％to other drugs.Candida tropicalis had resistance rates of 29.55％and 26.24％to fluconazole and voriconazole,respectively,resistance rates of 76.60％and 21.99％to posaconazole and echinocandins non-wild-type strains(NWT),and a resistance rate of 2.36％to echinocandins.Conclusions The prevalence and species distribution of Candida spp.in the East China region are consistent with previous domestic and international reports.Candida glabrata exhibits certain degree of resistance to fluconazole,while Candida tropicalis demonstrates higher resistance to triazole drugs.Additionally,echinocandins resistance has emerged in Candida albicans,Candida glabrata,Candida tropicalis,and Candida parapsilosis.

Objective:To evaluate the efficacy of 3D printed individualised prosthesis in treating bone and joint defects in upper limbs remained after earlier microsurgical repairs.Methods:From June 2019 to September 2021, 12 patients were treated in the Institute of Orthopaedic Trauma of PLA, the 80th Group Army Hospital for bone and joint defects in upper limb that had been remained after earlier repairs with soft tissue flaps. The defects were: 1 in completely severed wrist, 2 defects of digit metacarpal bone, 4 defects of interphalangeal joint, 4 defects of bones in radiocarpal joint and 1 defect of lunate bone. The area of soft tissue defect ranged from 1.5 cm×3.0 cm to 12.0 cm×18.0 cm, and the length of bone defects ranged from 2.5 to 8.5(average 3.64) cm. For incompletely severed and completely severed limbs, replantation of severed limbs (digits) were performed in the primary surgery and the repair of soft tissue defects were performed in the second stage surgery. The remaining defects of bone and joint were reconstructed by 3D printed individualised prostheses in the third stage surgery. Finger soft tissue defects were covered with a local flap in the primary surgery, and bone and joint defects were reconstructed with a 3D printed prosthesis in the second surgery. Finger soft tissue defects were covered with a local flap in the first phase, and bone and joint defects were reconstructed with a 3D printed prosthesis in the second phase. After the surgery, the bone integration between the broken end of the bone joint defect and the prosthesis was determined based on the X-ray results and the Paley fracture healing score standard. Simultaneously measured the Total Active Motion(TAM) of the forearm and hand joints. At 1, 2, 3, 6, 9 and 12 months after hospital discharge. Follow-up X-ray examinations were taken followed by examinations on the recovery of soft tissues and bones. The upper limb function was graded according to the Evaluation Trial Standards of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association.Results:Postoperative follow-up at outpatient clinic lasted for 6 to 26 months, with an average of 11.5 months. All flaps were free from necrosis and infection, also there was no infection in bones and joints. According to the Paley fracture healing scale, 10 patients were in excellent and 2 in good. In addition, according to the Evaluation Trial Standards of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association, 5 patients achieved upper limb function in excellent, 5 in good and 2 in fair. The ranges of motion of the affected wrists were 30°-42°(average 37.3°) for the implanted prostheses of distal end of radius and the radial shaft. Wrist flexion 40° to 55°(average 43.5°). The range of motion of finger and wrist was 60° to 70°(average 65.7°) with a metacarpal and phalangeal bone prosthesis.Conclusion:3D printed individually customised prostheses are safe, accurate and effective in repair of the remained bone and joint defects in upper limbs after primary and early stages of microsurgical flap repairs. It can effectively restore anatomical structures of bone and joint in upper limbs.

Volatile components of Lonicerae Japonicae Flos in bud stage extended type Beihua 1 were determined by the headspace solid-phase micro-extraction, compared with traditional cultivar Damaohua. There are fifty-two volatile compounds were identified and the relative content of the volatiles was calculated by the area normalization method. Thirty-nine compounds were found in Beihua 1, whereas thirty-three components in Damaohua. Total twenty identical compounds existed in Beihua 1 and Damaohua. The contents of alcohols and hydrocarbons of Beihua 1 were higher significantly than that of Damaohua, while significantly lower than that of Damaohua in ketones content. Besides, twenty components were only detected in Beihua 1, such as methyl nicotinate, hexadecanoic acid, methyl ester,acetophenone, nonanoic acid.

BACKGROUNDAccumulating evidence indicates a potential role of adventitial vasa vasorum (VV) dysfunction in the pathophysiology of restenosis. However, characterization of VV vascularization in restenotic arteries with primary lesions is still missing. In this study, we quantitatively evaluated the response of adventitial VV to vascular injury resulting from balloon angioplasty in diseased arteries.

METHODSPrimary atherosclerotic-like lesions were induced by the placement of an absorbable thread surrounding the carotid artery of New Zealand rabbits. Four weeks following double-injury induced that was induced by secondary balloon dilation, three-dimensional patterns of adventitial VV were reconstructed; the number, density, and endothelial surface of VV were quantified using micro-computed tomography. Histology and immunohistochemistry were performed in order to examine the development of intimal hyperplasia.

RESULTSResults from our study suggest that double injured arteries have a greater number of VV, increased luminal surface, and an elevation in the intima/media ratio (I/M), along with an accumulation of macrophages and smooth muscle cells in the intima, as compared to sham or single injury arteries. I/M and the number of VV were positively correlated (R2 = 0.82, P < 0.001).

CONCLUSIONSExtensive adventitial VV neovascularization occurs in injured arteries after balloon angioplasty, which is associated with intimal hyperplasia. Quantitative assessment of adventitial VV response may provide insight into the basic biological process of postangioplasty restenosis.

OBJECTIVETo evaluate computed tomography (CT) and magnetic resonance imaging (MRI) findings in patients with autoimmune pancreatitis (AIP).

METHODSThe imaging findings of pancreas and extra-pancreas in 24 patients with AIP were retrospectively reviewed. Among them, CT scan was performed in 18 patients, MRI in 11, and bGth CT and MRI in 10.

RESULTSThe pancreas showed diffuse enlargement (25%, 6/24), focal enlargement (37. 5%, 9/24), combined enlargement (25%, 6/24) ,and no enlargement (12. 5%, 9/24). Unenhanced CT showed hypoattenuation in AIP area (n = 2) . After intravenous injection of contrast medium, 17 patients showed abnormal contrast enhancement in the affected pancreatic parenchyma, including hypoattenuation during the arterial phase (50%, 9/18) and hyper attenuation during the delayed phase (94. 4%, 17/18). Precontrast MRI showed abnormal signal intense (n =9), including hypointense on T1-weight images (T1 WI) (n = 7), hyperintense (n = 7) and hypointense (n = 2) on T2-weight images (TIWI). Enhanced MRI demonstrated abnormal contrast enhancement within lesions (n = 11), including hypoattenuation during the arterial phase (81. 8%, 9/11) and good enhancement during the delayed phase (100%, 11111). A capsule-like rim was seen around pancreas (37. 5%, 9/24), among which CT detected in 6 out of 18 patients and MRI found in 7 out of 11 patients.The main pancreatic duct lumen within lesions has no visualization (100%, 24/24) and upstream dilation of the main pancreatic duct (n = 8) , ranging from 2. 2 to 4. 5 mm(mean 3. 1 0. 47 mm) in diameter. Narrowing of the common bile duct was shown in 14 patients. Miscellaneous findings were: infiltration of extrapancreatic vein (n = 9) and artery (n = 1); mild fluid collection around pancreas (n = 2); pseudocysts (n = 3). Fourteen patients also presented one or more of the following extrapancreatic imaging findings: narrowing of the intra-hepatic bile duct or hilar duct (n = 5); thickening of gallbladder wall (n = 5); fibrosis in mesenteric (n = 2), in retroperitoneal (n = 2) and in ligamentum teres hepatis (n = 1); renal involvement (n = 3); peri-pancreatic or para-aortic lymphadenopathy (n = 10); and ulcerative colitis (n = 3).

CONCLUSIONAIP display some characteristic CT and MRI imaging features: sausage-like change of the pancreas; capsule-like rims around lesions; delayed contrast enhancement in the affected pancreatic parenchyma; segment or diffuse pancreatic duct stenosis but mild upstream dilation and extrapancreatic organs involvement. CT and MRI findings combining with serological tests and pancreas biopsy can assist physicians to make accurate and timely diagnosis.
