ABSTRACT

Objective:To clarify the changes of intrahepatic ultrasound hemodynamics before and after hepatic artery thrombosis (HAT) after liver transplantation (LT), providing early warning and anticoagulation guidance to clinicians.Methods:The clinical data of patients who underwent liver transplantation at Zhongshan Hospital of Fudan University between June 2006 and October 2022 were retrospectively analyzed, 47 patients with a diagnosis of HAT confirmed by DSA (digital subtraction angiography) were included in the HAT group, and 71 patients without vascular complications were included in the non-HAT group. Differences in peak flow velocity (PSV), resistance index (RI), and portal vein velocity (PVV) were compared between the two groups. Logistic regression analysis was used to determine the relationship between postoperative PSV decline and HAT occurrence, while ROC curve were used to determine the critical value and evaluate the diagnostic efficacy. Patients with HAT were divided into well-treatment group and poor-treatment group according to whether the blood flow was restored after multiple surgeries or thrombolytic treatments. The changes of early intrahepatic hemodynamics after surgical or thrombolytic therapy were compared between the two groups.Results:①A decrease in PSV of the transplanted hepatic artery was measured 1 d before HAT, and PSV<0.39 m/s predicted thrombus formation with a sensitivity of 0.70, specificity of 0.86, and the AUC was 0.83. ②After treatment, PSV in the HAT group increased immediately, approaching the normal level on the 2nd day. In the well-treatment group, PSV and PVV reached normal levels on the first day after treatment, which were significantly higher than the corresponding values in the poor-treatment group ( P=0.030, 0.021). Conclusions:In the early stage after liver transplantation, a PSV<0.39 m/s is related to the occurrence of HAT thrombosis 1 d later. A significant increase in PSV on the first day after treatment indicates a good treatment response, and there is no need for further DSA re-examination or increasing the number of thrombolysis.

ABSTRACT

Purpose@#Li-Fraumeni syndrome (LFS) is a hereditary disorder caused by germline mutation in TP53. Owing to the rarity of LFS, data on its clinical features are limited. This study aimed to evaluate the clinical characteristics and prognosis of Korean patients with LFS. @*Materials and Methods@#Patients who underwent genetic counseling and confirmed with germline TP53 mutation in the National Cancer Center in Korea between 2011 and 2022 were retrospectively reviewed. Data on family history with pedigree, types of mutation, clinical features, and prognosis were collected. @*Results@#Fourteen patients with LFS were included in this study. The median age at diagnosis of the first tumor was 32 years. Missense and nonsense mutations were observed in 13 and one patients, respectively. The repeated mutations were p.Arg273His, p.Ala138Val, and pPro190Leu. The sister with breast cancer harbored the same mutation of p.Ala138Val. Seven patients had multiple primary cancers. Breast cancer was most frequently observed, and other types of tumor included sarcoma, thyroid cancer, pancreatic cancer, brain tumor, adrenocortical carcinoma, ovarian cancer, endometrial cancer, colon cancer, vaginal cancer, skin cancer, and leukemia. The median follow-up period was 51.5 months. Two and four patients showed local recurrence and distant metastasis, respectively. Two patients died of leukemia and pancreatic cancer 3 and 23 months after diagnosis, respectively. @*Conclusion@#This study provides information on different characteristics of patients with LFS, including types of mutation, types of cancer, and prognostic outcomes. For more appropriate management of these patients, proper genetic screening and multidisciplinary discussion are required.

ABSTRACT

Background@#Distal metaphyseal-diaphyseal junction fractures of the humerus are a subset of injuries between humeral shaft fractures and distal intra-articular humerus fractures. A lack of space for distal fixation and the unique anatomy of concave curvature create difficulties during operative treatment. The closely lying radial nerve is another major concern. The aim of this study was to determine whether anterolateral dual plate fixation could be effective for a distal junctional fracture of the humerus both biomechanically and clinically. @*Methods@#A right humerus 3-dimensional (3D) model was obtained based on plain radiographs and computed tomography data of patients. Two fractures, a spiral type and a spiral wedge type, were constructed. Three-dimensional models of locking compression plates and screws were constructed using materials provided by the manufacturer. The experiment was conducted by using COMSOL Multiphysics, a finite element analysis, solver, and simulation software package. For the clinical study, from July 2008 to March 2021, a total of 72 patients were included. Their medical records were retrospectively reviewed to obtain patient demographics, elbow range of motion, Disabilities of the Arm, Shoulder and Hand (DASH) scores, Mayo Elbow Performance Scores (MEPS), and hand grip strength. @*Results@#No fracture fixation construct completely restored stiffness comparable to the intact model in torsion or compression. Combinations of the 7-hole and 5-hole plates and the 8-hole and 6-hole plates showed superior structural stiffness and stress than those with single lateral plates. At least 3 screws (6 cortices) should be inserted into the lateral plate to reduce the load effectively. For the anterior plate, it was sufficient to purchase only the near cortex. Regarding clinical results of the surgery, the range of motion showed satisfactory results in elbow flexion, elbow extension, and forearm rotation. The average DASH score was 4.3 and the average MEPS was 88.2. @*Conclusions@#Anterolateral dual plate fixation was biomechanically superior to the single-plate method in the finite element analysis of a distal junctional fracture of the humerus model. Anterolateral dual plate fixation was also clinically effective in a large cohort of patients with distal junctional fractures of the humerus.

ABSTRACT

Purpose@#This study investigated pathological complete response (pCR) according to androgen receptor (AR) in breast cancer patients undergoing neoadjuvant chemotherapy and estimated the relationship between AR expression and clinicopathological factors. @*Materials and Methods@#We identified 624 breast cancer patients who underwent surgery after neoadjuvant chemotherapy at the National Cancer Center in Goyang, Korea from April 2016 to October 2019. We retrospectively collected the clinicopathologic information and AR expression results and analyzed the data according to cancer stage, hormonal receptor (HR) status, human epidermal growth factor receptor 2 (HER2) status, tumor subtype, and pCR. @*Results@#Among the 624 breast cancer patients, 529 (84.8%) were AR-positive (AR+) patients and 95 (15.2%) were AR-negative (AR–) patients. AR+ patients showed more estrogen receptor (ER) positivity, progesterone receptor (PR) positivity, HER2-positivity, and HR-positive and HER2-negative (HR+/HER2–) subtype. The rate of pCR was 31.4% (196/624). AR– patients had a significantly higher rate of pCR than AR+ patients (AR– 43.2% vs. AR+ 29.3%, p=0.007). The tumor factors associated with pCR were early stage, histologic grade 3, ER-negative, PR-negative, AR-negative, HER2-positive, and high Ki-67 values. In univariable analysis, AR+ significantly decreased the state of pCR (odds ratio, 0.546; 95% confidence interval, 0.349 to 0.853; p=0.008). According to tumor subtype, AR– tumor showed higher pCR rate in HR+/HER2– subtype (AR– 28.6% vs. AR+ 7.3%, p=0.022). @*Conclusion@#AR expression is predominant in the HR+/HER2– subtype. AR– is significantly associated with the pCR rate in breast cancer patients, especially within HR+/HER2– subtype. When determining neoadjuvant chemotherapy for the HR+/HER2– subtype, AR expression can be considered as a pCR predictive marker.

ABSTRACT

Background and Objectives@#The canal wall down mastoidectomy brings changes in the anatomy of the external auditory canal (EAC), causing potential problems, such as accumulated crust, vertigo attacks, and difficulties in wearing hearing aids (HAs). The objective of this study is to evaluate the safety and efficacy of mastoidoplasty using the demineralized bone matrix (DBM) to obliterate the mastoidectomized cavity and reconstruct EAC.Subjects and Method Medical records of patients with chronic otitis media with or without cholesteatoma who received mastoidoplasty using DBM by a single surgeon at Seoul St. Mary’s hospital between 2014 and 2021 were reviewed retrospectively. @*Results@#A total of 27 patients were included in this study. None of the patients showed any recurrence of cavity problem, wound infection, or any other complications during their followup period of 13.07±37 months. The average air and bone conduction hearing level of pure tone audiometry showed no significant change after surgery (p=0.50, p=0.54, respectively). Five patients indicated for hearing rehabilitation could adopt canal type HAs after surgery; six patients used completely-in-the canal type HAs, and one patient used in-the-canal type HAs. None of the patients using HAs complained of acoustic feedback or any other problem in wearing HAs. @*Conclusion@#Mastoidoplasty using DBM seems to be a very safe and effective surgical procedure that shows functionally acceptable EAC for hearing rehabilitation with canal type HAs and demonstrates no specific complication.

ABSTRACT

Aim To investigate the protective effect of hesperidin (HES) on cardiorenal damage induced by DOCA/Salt hypertension and the underlying mechanisms. Methods Eighteen male SD rats were randomly divided into normal group (Ctrl), model group (DOCA/Salt), and DOCA/Salt with hesperidin group (DOCA/Salt + HES). HES was administered for four weeks. Blood pressure, serum creatinine and blood urea nitrogen were measured. The pathological changes in heart and kidney were examined by HE, Masson and Sirius red staining. The expression of α-SMA, collagen I and TGF-β were detected by Western blot. The mRNA levels of Nlrp3, TNF-α, IL-1β, IL-6 and NOXs were measured using qRT-PCR. Results Compared with the model group, HES administration significantly attenuated the occurrence of DOCA/Salt hypertension, improved renal function indicators of hypertensive rats, reduced renal and cardiac fibrosis, deduced the expression of α-SMA, collagen I and TGF-β, inhibited the expression of Nlrp3, TNF-α, IL-1β and IL-6, and decreased the expression of NOXs in renal and cardiac tissues. Conclusions HES can delay the occurrence of hypertension and protect against hypertension-induced renal and cardiac tissue damage, which may be related to the reduction of inflammatory reaction and oxidative stress by HES.

ABSTRACT

Purpose@#Fertility preservation (FP) is an important issue for young survivors of breast cancer. Although international guidelines recommend pre-treatment fertility counseling for women with breast cancer, there is no standardized protocol or referral system for FP in South Korea. There are also barriers to discussing FP that make patient-centered decision making difficult. This study aimed to develop a shared decision making program for FP and compare the rates of FP procedures between the usual care and shared decision making groups. We hypothesized that multidisciplinary shared decision making for FP would increase the rate of FP procedures and patient satisfaction. @*Methods@#The multidisciplinary shared decision making for FP in young women with breast cancer (MYBC) is a multicenter, clustered, stepped-wedge, randomized trial. A total of 1100patients with breast cancer, aged 19–40 years, from nine hospitals in South Korea, will be enrolled. They will be randomized at the institutional level and assigned to usual care and shared decision making groups. Four institutions, each of which can recruit more than 200 patients, will each become a cluster, whereas five institutions, each of which can recruit more than 50 patients, will become one cluster, for a total of five clusters. The shared decision making groups will receive multidisciplinary programs for FP developed by the investigator. The primary outcome is the rate of FP procedures; secondary outcomes include fertility results, satisfaction, and quality of life. Outcomes will be measured at enrollment, treatment initiation, and the 1-, 3-, and 5-year follow-ups after starting breast cancer treatment.Discussion: A multidisciplinary shared decision making program for FP is expected to increase fertility rates and satisfaction among young patients with breast cancer. This study will provide the evidence to implement a multidisciplinary system for patients with breast cancer.

ABSTRACT

OBJECTIVES@#To investigate the clinical application of metagenomic next-generation sequencing (mNGS) of bronchoalveolar lavage fluid (BALF) in the etiological diagnosis and treatment of refractory pneumonia (RTP) in children.@*METHODS@#A retrospective analysis was performed on 160 children with RTP who were admitted to the Department of Pediatric Internal Medicine, Maternal and Child Health Hospital of Inner Mongolia Autonomous Region, from January 2020 to March 2023. According to whether mNGS was performed, they were divided into two groups: mNGS (n=80) and traditional testing (n=80). All children received the tests of inflammatory markers and pathogen tests after admission. Traditional pathogenicity tests included microbial culture (sputum specimen collected by suction tube), nucleic acid detection of respiratory pathogens, and serological test (mycoplasma, tuberculosis, and fungi). For the mNGS group, BALF specimens were collected after bronchoscopy and were sent to the laboratory for mNGS and microbial culture. The two groups were analyzed and compared in terms of the detection of pathogens and treatment.@*RESULTS@#Compared with the traditional testing group, the mNGS group had a significantly higher detection rate of pathogens (92% vs 58%, P<0.05), with more types of pathogens and a higher diagnostic rate of mixed infections. Compared with the traditional testing group, the mNGS group had a significantly higher treatment response rate and a significantly lower incidence rate of complications during hospitalization (P<0.05). Treatment was adjusted for 68 children in the mNGS group according to the results of mNGS, with a treatment response rate of 96% (65/68) after adjustment.@*CONCLUSIONS@#Compared with traditional pathogen tests, BALF mNGS can significantly improve the detection rate of pathogens and find some rare pathogens. In clinical practice, when encountering bottlenecks during the diagnosis and treatment of children with RTP, it is advisable to promptly perform the mNGS to identify the pathogens.

ABSTRACT

What are the new contents of the guideline since 2010?A.Patients with primary and non-primary sclerosing cholangitis (PSC) are included in these guidelines for the diagnosis and management of cholangiocarcinoma.B.Define "related stricture" as any biliary or hepatic duct stricture accompanied by the signs or symptoms of obstructive cholestasis and/or bacterial cholangitis.C.Patients who have had an inconclusive report from MRI and cholangiopancreatography should be reexamined by high-quality MRI/cholangiopancreatography for diagnostic purposes. Endoscopic retrograde cholangiopancreatography should be avoided for the diagnosis of PSC.D. Patients with PSC and unknown inflammatory bowel disease (IBD) should undergo diagnostic colonoscopic histological sampling, with follow-up examination every five years until IBD is detected.E. PSC patients with IBD should begin colon cancer monitoring at 15 years of age.F. Individual incidence rates should be interpreted with caution when using the new clinical risk tool for PSC for risk stratification.G. All patients with PSC should be considered for clinical trials; however, if ursodeoxycholic acid (13-23 mg/kg/day) is well tolerated and after 12 months of treatment, alkaline phosphatase (γ- Glutamyltransferase in children) and/or symptoms are significantly improved, it can be considered to continue to be used.H. Endoscopic retrograde cholangiopancreatography with cholangiocytology brushing and fluorescence in situ hybridization analysis should be performed on all patients suspected of having hilar or distal cholangiocarcinoma.I.Patients with PSC and recurrent cholangitis are now included in the new unified network organ sharing policy for the end-stage liver disease model standard.J. Liver transplantation is recommended after neoadjuvant therapy for patients with unresectable hilar cholangiocarcinoma with diameter < 3 cm or combined with PSC and no intrahepatic (extrahepatic) metastases.

ABSTRACT

Background@#Studies have reported favorable outcomes using the paratricipital approach for fixation of distal humeral intra-articular fractures. However, literature evaluating the clinical results of the approach remains limited. The objective of this study was to compare clinical outcomes between type 13C2 and type 13C1 distal humeral fractures after open reduction and internal fixation performed using the same approach and same type of plate. @*Methods@#A total of 52 adults with type 13C1 or 13C2 distal humeral fractures were treated surgically at our institution during 2006 to 2018. We retrospectively analyzed data from 29 of these patients (19 with type 13C1 fractures and 10 with 13C2 fractures) who met the inclusion criteria. All subjects were followed for a minimum of 2 years postoperatively. Clinical and radiologic results were analyzed to determine differences in outcomes between the two types of fractures. Clinical results were evaluated using elbow range of motion (ROM), Mayo Elbow Performance Score (MEPS), and Quick Disabilities of the Arm, Shoulder and Hand (Q-DASH) score. Alignment, fracture union, and presence of posttraumatic arthritis were evaluated radiologically. @*Results@#The patients’ mean age was 51 years, and the mean duration of follow-up was 29 months. Mean ROM was 129.5° ± 21.5° in the type 13C1 group and 123.0° ± 20.6° in the 13C2 group (p = 0.20). Mean Q-DASH score was 12.6 ± 11.7 in the 13C1 group and 16.2 ± 19.8 in the 13C2 group (p = 0.60). Mean MEPS was 92.9 ± 8.5 in the 13C1 group and 85.0 ± 14.1 in the 13C2 group (p = 0.09). Carrying angle did not differ significantly between the 13C1 and 13C2 groups. No patient in either group exhibited nonunion or posttraumatic arthritis. @*Conclusions@#Although the paratricipital approach has the disadvantage of limited visualization of articular surfaces, there were no differences in surgical outcomes between type 13C1 and type 13C2 distal humeral fractures after fixation using this approach.Thus, surgeons may need to consider using the paratricipital approach for open reduction and internal fixation of 13C2 distal humeral fractures.

ABSTRACT

Objective: To investigate the postoperative prognostic factors of non-metastatic colorectal cancer (non-mCRC), and construct a prognostic prediction model. Methods: A total of 846 patients with colorectal cancer who were admitted to the Cancer Hospital, Chinese Academy of Medical Sciences from July 1, 2014 to December 31, 2016 were included in the study. There were 314 patients in the metastatic colorectal cancer (mCRC) group and 532 patients in the non-mCRC group. The data of clinical characteristics, preoperative blood routine and common serum tumor markers for CRC tests were collected retrospectively. The disease-free survival time (DFS) data of patients in non-mCRC group were obtained by follow-up. Univariate and multivariate Cox regression analyses were used to clarify the independent risk factors of DFS, and then these factors were included to construct a nomogram prediction model. The concordance index (C index), receiver operating characteristic curve (ROC) and calibration curve were used to evaluate the performance of the model. Results: Platelet/lymphocyte ratio (PLR), neutrophil/lymphocyte ratio (NLR), carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9) and carbohydrate antigen 242 (CA242) in the mCRC group were higher than those of the non-mCRC group, while the lymphocyte/monocyte ratio (LMR) was lower than that of the non-mCRC group (P<0.05). ROC analysis showed that the area under curve (AUC) of CEA, CA19-9, CA242, NLR, LMR and PLR for the diagnosis of mCRC were 0.775, 0.716, 0.712, 0.607, 0.591 and 0.556, respectively. Multivariate Cox regression analysis demonstrated that age, perineural invasion, pN stage and preoperative CA242 level were independent risk factors for DFS of non-mCRC patients (P<0.05). Based on this, a nomogram prediction model predicting 3 years of DFS for non-mCRC patients was constructed, its C index and AUC for non-CRC prognostic prediction were 0.710 and 0.733, respectively, higher than 0.696 and 0.701 of AJCC 7th edition TNM staging system. The calibration curve of nomogram showed that the predicted DFS rate was consistent with the actual DFS rate. Conclusions: Age, perineural invasion, pN stage and preoperative CA242 level are independent risk factors for 3-year DFS of non-mCRC patients. The nomogram prediction model constructed based on these four indictors has a good predictive performance and may provide prognosis evaluation reference for the patients with non-mCRC.

ABSTRACT

Purpose@#Various problems have been reported with tension-band wire (TBW) fixation. With the devel-opment of anatomical plates and the improvement of fixation forces, plate fixation is currently being performed for non-comminuted, displaced, transverse olecranon fractures (Mayo Type 2A). This study compared the usefulness of the above two procedures applied in non-comminuted, displaced, transverse olecranon fractures. @*Materials and Methods@#Fifty-three patients with Mayo Type 2A were studied retrospectively. Twenty-nine patients underwent TBW fixation, while the other 24 underwent plate fixation. The averageoutpatient follow-up period was 10 months for both groups. Both groups were analyzed radiologically and clinically. The radiological assessment included the time to bone union, joint stability, and presence of traumatic osteoarthritis at the final follow-up. The clinical assessment included the operation time,range of motion of the elbow joint, Mayo Elbow Performance Score (MEPS), Disability of the Arm, Shoulder and Hand (DASH) score, and the presence of postoperative complications. @*Results@#Both groups showed stable elbow joints, proper union of fractures, and no traumatic osteo-arthritis at the final follow-up. The range of motion for the TBW fixation group was 142° (range, 3°-145°), while that of the plate fixation group was 135° (range, 4°-139°) at the final follow-up (p=0.219). The MEPS was 98.2 and 97.7 for the TBW fixation and plate fixation groups, respectively (p=0.675). The DASH score was 10.7 and 13.9 for the TBW fixation and plate fixation groups, respectively. Both groups showed excellent results, and the differences were not statistically significant (p=0.289). @*Conclusion@#TBW fixation and plate fixation were compared in non-comminuted, displaced, transverse olecranon fractures, and good results were obtained without significant differences between the two groups. Hence, surgeons should choose a technique they are more confident with and can be applied more efficiently.

ABSTRACT

Purpose@#Fractures of the capitellum of the humerus are relatively rare injuries, and the prevalence is known to be less than 1% of all elbow fractures. Since the capitellum forms an articular surface with the radial head, this fracture is considered to be an intra-articular fracture, and surgical treatment is required for the displaced fracture. Due to the rarity of this type of fracture, only a few studies on treatment have been published. We report the results of cases that underwent surgical treatment for capitellum fractures. @*Materials and Methods@#Through a retrospective review, patients who underwent surgical treatment for a capitellum fracture from January 2002 to January 2020, and who could be followed-up for at least 12 months and were over 16 years old were included. A total of 19 patients who underwent open reduction and internal fixation with K-wires and headless compression screws were included.Radiographic analysis was carried out using simple radiographs taken to investigate the stability of the joint and the union of fractures.Clinical results were analyzed using the range of motion of the elbow, visualized pain score, Mayo Elbow Performance score (MEPS), Disabilities of the Arm, Shoulder and Hand (DASH) score, and postoperative complications were analyzed at the time of the final follow-up. @*Results@#The average age of the patients was 57.3 years, and their average follow-up time was 22.6 months. Most of them were type I (n=12) as per the Bryan–Morrey classification. The radiographic analysis showed that bony union was obtained at the final follow-up in all cases, and there was no case of joint instability. The results of the clinical analysis showed that average flexion contracture was 9.7° (min 0°–max 30°), average further flexion was 130.3° (min 90°–max 145°), and average range of motion was 120.5°, and the average visualized pain score at the final follow-up was 1.3 (min 0–max 3). At the final follow-up, the average MEPS was 85.5 (min 75–max 95) and the average DASH score was 27.6 (min 5–max 46), which was satisfactory. @*Conclusion@#With early rehabilitation, capitellum fractures can be treated well without complications if the joint surface is aligned congruently with open reduction and firm fixation by using K-wire or headless compression screws.

ABSTRACT

Objective To identify the differentially expressed proteins in different liver tissues in the mouse model of cystic echinococcosis (CE), so as to provide insights into the research and development of therapeutic drugs targeting CE. Methods Female Kunming mice at ages of 6 to 8 weeks were randomly assigned into the CE group and the control group. Mice in the CE group were intraperitoneally infected with 2 000 Echinococcus multilocularis protoscoleces, while mice in the control group were injected with the same volume of physiological saline. All mice in both groups were sacrificed after breeding for 350 d, and the lesions (the lesion group) and peri-lesion specimens (the peri-lesion group) were sampled from the liver of mice in the CE group and the normal liver specimens (the normal group) were sampled from mice in the control group for data independent acquisition (DIA) proteomics analysis, and the differentially expressed proteins were subjected to Gene Ontology (GO) term enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis. Results A total of 26 differentially expressed proteins were identified between the lesion group and the normal group and between the peri-lesion group and the normal group, including 8 up-regulated proteins and 18 down-regulated proteins. GO term enrichment analysis showed that these differentially expressed proteins were predominantly enriched in endoplasmic reticulum membrane (biological components), oxidoreductase activity (molecular function) and oxoacid metabolic process and monocarboxylic acid metabolic process (biological processes). KEGG pathway enrichment analysis revealed that the differentially expressed protein Acyl-CoA oxidase 1 (Acox1), which contributed to primary bile acid biosynthesis during the fatty acid oxidation, was involved in peroxisome signaling pathway, and the differentially expressed protein fatty acid binding protein 1 (Fabp1), which contributed to fatty acid transport, was involved in the peroxisome proliferator-activated receptor (PPAR) signaling pathway. Conclusion Differentially expressed proteins are identified in the liver specimens between mouse models of CE and normal mice, and some differentially expressed proteins may serve as potential drug targets for CE.

ABSTRACT

Objective To identify the differentially expressed proteins in different liver tissues in the mouse model of alveolar echinococcosis using high-resolution mass spectrometry with data independent acquisition (DIA), and to identify the key proteins contributing to the pathogenesis of alveolar echinococcosis. Methods Protoscoleces were isolated from Microtus fuscus with alveolar echinococcosis and the experimental model of alveolar echinococcosis was established in female Kunming mice aged 6 to 8 weeks by infection with Echinococcus multilocularis protoscoleces. Mice were divided into the experimental and control groups, and animals in the experimental group was injected with approximately 3 000 protoscoleces, while mice in the control group were injected with the same volume of physiological saline. Mouse liver specimens were sampled from both groups one year post-infection and subjected to pathological examinations. In addition, the lesions (the lesion group) and peri-lesion specimens (the peri-lesion group) were sampled from the liver of mice in the experimental group and the normal liver specimens (the normal group) were sampled from mice in the control group for DIA proteomics analysis, and the differentially expressed proteins were subjected to bioinformatics analysis. Results A total of 1 020 differentially expressed proteins were identified between the lesion group and the normal group, including 671 up-regulated proteins and 349 down-regulated proteins, and 495 differentially expressed proteins were identified between the peri-lesion group and the normal group, including 327 up-regulated proteins and 168 down-regulated proteins. The Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis revealed that these differentially expressed proteins were involved in peroxisome, peroxisome proliferator-activated receptor (PPAR) and fatty acid degradation pathways, and the peroxisome and PPAR signaling pathways were found to correlate with liver injury. Several differentially expressed proteins that may contribute to the pathogenesis of alveolar echinococcosis were identified in these two pathways, including fatty acid binding protein 1 (Fabp1), Acyl-CoA synthetase long chain family member 1 (Acsl1), Acyl-CoA oxidase 1 (Acox1), Enoyl-CoA hydratase and 3-hydroxyacyl CoA dehydrogenase (Ehhadh) and Acetyl-Coenzyme A acyltransferase 1B (Acaa1b), which were down-regulated in mice in the experimental group. Conclusion A large number of differentially expressed proteins are identified in the liver of the mouse model of alveolar echinococcosis, and Fabp1, Acsl1, Acox1, Ehhadh and Acaa1b may contribute to the pathogenesis of alveolar echinococcosis.

ABSTRACT

The Baveno VII workshop held in October 2021 was featured by the subject of personalized care in portal hypertension. The workshop focused on the following 9 topics including: the relevance and indications for measuring the hepatic venous pressure gradient as a gold standard; the use of non-invasive tools for the diagnosis of compensated advanced chronic liver disease and clinically significant portal hypertension; the impact of etiological and of non-etiological therapies in the course of cirrhosis; the prevention of the first episode of decompensation; the management of the acute bleeding episode; the prevention of further decompensation; as well as the diagnosis and management of splanchnic vein thrombosis and other vascular disorders of the liver. This essay provides a compilation and summary of recommendations regarding the abovementioned topics, and presents the most recent research proceedings and the corresponding consensus to our readers.

ABSTRACT

Objective:To investigate the clinical feasibility of three-dimensional contrast-enhanced ultrasound (3D-CEUS) in the quantitative assessment of blood perfusion of hepatocellular carcinoma (HCC).Methods:Between January 2020 and August 2021, 36 HCC patients (39 lesions in total) confirmed by pathology and clinical diagnosis without any treatment from Zhongshan Hospital, Fudan University were enrolled and underwent both 2D-CEUS and 3D-CEUS examinations. Each examination last for 150 s and all images were recorded, and then the data were analyzed. A region of interest was manually drawn along the margin of the whole tumor and then the time-intensity curve (TIC) generated. The following perfusion parameters were extracted: peak intensity (PI), peak time (TTP), ascending slope (AS), mean transit time (MTT) and area under the curve (AUC). After calculating the quality of fit (QOF) of the curve, the intraobserver agreement of the 3D-CEUS quantitative parameters obtained by the same doctor between two times were assessed, and the consistency of the 3D-CEUS and 2D-CEUS quantitative parameters was evaluated when QOF>75%. The differences of the quantitative parameters between different groups (divided by depth of 8 cm and necrosis rate of 50%, respectively) in 3D-CEUS were compared.Results:There were 38 lesions (97.4%, 38/39) with QOF>75% in 3D-CEUS. The intraobserver agreement was excellent, the intraclass correlation efficient(ICC) values was 0.85-0.99. The consistency of the time quantitative parameters (TTP and MTT) were high (the ICC values of 0.87 and 0.91), and the correlation of intensity quantitative parameters were substantial, the rs values were 0.71, 0.72 and 0.71. The differences in 3D-CEUS quantitative parameters of the two groups of lesions with different depths were statistically significant (all P<0.05); but there were no significant differences in quantitative parameters between the two groups with different necrosis rate (all P>0.05). Conclusions:Quantitative 3D-CEUS is an useful and creditable tool in evaluating the blood perfusion of HCC, especially when the depth of lesion was less than 8 cm.

ABSTRACT

Objective:To investigate the incidence, risk factors and prognosis of acute renal injury(AKI)in elderly patients with respiratory distress syndrome(ARDS).Methods:The elderly patients with ARDS treated in the Department of Respiratory Medicine, Emergency Department and Geriatrics of the Second People's Hospital of Lianyungang from July 2016 to July 2019 were divided into AKI group and non-AKl group according to KDIGO diagnostic criteria.The clinical data and the differences were compared and analyzed between the two groups.Binary Logistic regression was used to analyze Risk factors for AKI.Kaplan-Meier cure was used to analyze the influence of different stages of AKI on the prognosis of ARDS patients.The Cox proportional hazards model was used to analysis risk factors for AKI and ARDS on elderly patients'prognosis.Results:A total of 432 elderly patients with ARDS were enrolled in the study, in which the mean age was 74.7 ± 8.8 years, and AKI occurred in 129 cases(29.9%). Compared with non-AKI group, AKI group showed older age, and higher proportion of the incidences of hypertension, diabetes, atrial fibrillation, consciousness disturbance, mechanical ventilation and a low mean arterial pressure(all P<0.05). The incidence of AKI was increased significantly in patients with moderate to severe ARDS( P< 0.001). The levels of basal creatinine, AST and NT-proBNP were significantly higher in AKI Group than in non-AKI Group( P= 0.001, P< 0.001, P< 0.001). AKI Group patients had the more elevated inflammatory marker level of neutrophil / lymphocyte ratio(NLR)( P= 0.003)and D-dimer( P< 0.001), and the level of high-sensitivity c-reactive protein(hsCRP)( P=0.040). AKI group showed the increased incidence of urine protein( P< 0.001), low ejection fraction( P= 0.040), and positive rate of pleural effusion( P= 0.003). Logistic Regression analysis showed the following independent risk factors for the development of ARDS-associated AKI, included hypertension( OR: 1.789, 95%, CI: 1.105-2.894, P=0.018), diabetes( OR: 1.976, 95% CI: 1.076-3.628, P=0.028), consciousness disturbance( OR: 2.531, 95% CI: 1.203-5.251, P=0.014), mechanical ventilation( OR: 3.421, 95% CI: 1.521-7.694, P=0.003), AST>40 U/L( OR: 2.495, 95% CI: 1.431-4.348, P=0.001), increased basal creatinine levels( OR: 1.014, 95% CI: 1.002-1.027, P=0.024), and NLR( OR: 1.015, 95% CI: 1.001-1.029, P=0.042). Kaplan-Meier survival curve showed that there was a significant difference in the prognosis between patients with different AKI stages( χ2=19.790, P<0.001), and there was no significant difference in the prognosis between stage 1-AKI and non-AKI( χ2=2.188, P=0.139). The risk of poor prognosis was higher in AKI(stage 2-3)group( χ2=18.268, P<0.001; χ2=6.347, P=0.012)than in patients without AKI or stage 1 AKI.Multivariate Cox Proportional Hazard Model Analysis elucidated that AKI( HR: 1.858, 95% CI: 1.207-2.861, P= 0.005)and moderate-severe ARDS( HR: 1.815, 95% CI: 1.167-2.822, P=0.008)were independent risk factors for poor prognosis of ARDS in the elderly. Conclusions:Hypertension, diabetes, disturbance of consciousness, mechanical ventilation, AST>40 U/L, elevated levels of basal creatinine and NLR are independent risk factors for ARDS-associated AKI in elderly patients with ARDS.Patients with moderate-severe ARDS and AKI(2-3 phases)have the increased risk of poor prognosis.
