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

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

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@#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

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

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 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

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 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.

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

Background@#The rupture of the central slip of an extensor tendon of a finger causes a boutonniere (or buttonhole) deformity, characterized by pathologic flexion at the proximal interphalangeal (PIP) joint and hyperextension at the distal interphalangeal (DIP) joint. Currently, there are no standard treatment guidelines for this deformity. This study aimed to report clinical results of surgery to correct chronic boutonniere deformity. @*Methods@#This retrospective case series was conducted between January 2010 and December 2018 and only 13 patients with trauma-induced chronic deformity were included. After excision of elongated scar tissue, a direct anatomic end-to-end repair using a loop suture technique with supplemental suture anchor augmentation was conducted. Total active motion was assessed before and after surgery and self-satisfaction scores were collected from phone surveys. @*Results@#All patients presented with Burton stage I deformities defined as supple and passively correctable joints. The initial mean extension lag of the PIP joint (43.5°) was improved by an average of 21.9° at the final follow-up (p < 0.001). The mean hyperextension of the DIP joint averaged 19.2° and improved by 0.8° flexion contracture (p < 0.001). The average total active motion was 220.4° (range, 160°–260°). Based on the Souter’s criteria, 69.2% (9/13) of the patients had good results. Only 1 patient reported fair outcome and 23.1% (3/13) reported poor outcome. The average Strickland formula score was 70 (range, 28.6–97.1). In total, 10 patients (77%) had excellent or good results. Of 10 patients contacted by phone, self-reported satisfaction score was very satisfied in 2, satisfied in 3, average in 3, poor in 1, and very poor in 1. Three patients reported a relapse of the deformity during range of motion exercises, 1 of whom underwent revision surgery. One patient complained of PIP joint flexion limitation, and 2 complained of DIP joint flexion limitation at final follow-up. @*Conclusions@#In chronic boutonniere deformity, central slip reconstruction with anchor suture augmentation can be an easily applicable surgical option, which offers fair to excellent outcome in 77% of the cases. The risk of residual extension lag and recurrence of deformity should be discussed prior to surgery.

ABSTRACT

Objective:To evaluate the value of shear wave dispersion imaging in identifying inflammatory reaction zone after liver ablation in rabbits.Methods:The animal model was made by laser ablation of rabbit liver, and then shear wave dispersion imaging and strain elastography imaging were performed on the ablation area at 3 d, 7 d, and 14 d after ablation. The shear wave dispersion values, elastic value and strain ratio measured by shear wave elastography, shear wave dispersion and strain elastography in different regions such as central necrotic tissue, surrounding inflammatory reaction zone and normal liver tissue after ablation were analyzed.Results:The shear wave dispersion values of inflammatory reaction zone around ablation site, necrotic tissue in the center of ablation site and normal liver tissue in rabbits were (26.07±4.55)m·s -1·kHz -1, (21.97±10.53)m·s -1·kHz -1and (15.45±3.94)m·s -1·kHz -1, respectively, the differences were statistically significant (all P<0.05). Compared with the three time points of 3 d, 7 d and 14 d after ablation, the shear wave dispersion value of the inflammatory zone was the highest on the 7th day after ablation ( P<0.05), while the elastic value and strain ratio in this region did not change significantly among these three time points ( P>0.05). Conclusions:Shear wave dispersion imaging can simultaneously measure tissue elasticity and viscosity, which has certain application value in identifying the inflammatory reaction zone around the ablation site in rabbit liver.

ABSTRACT

BACKGROUND@#Bendamustine was approved in China on May 26th, 2019 by the National Medical Product Administration for the treatment of indolent B-cell non-Hodgkin lymphoma (NHL). The current study was the registration trial and the first reported evaluation of the efficacy, safety, and pharmacokinetics of bendamustine in Chinese adult patients with indolent B-cell NHL following relapse after chemotherapy and rituximab treatment.@*METHODS@#This was a prospective, multicenter, open-label, single-arm, phase 3 study (NCT01596621; C18083/3076) with a 2-year follow-up period. Eligible patients received bendamustine hydrochloride 120 mg/m2 infused intravenously on days 1 and 2 of each 21-day treatment cycle for at least six planned cycles (and up to eight cycles). The primary endpoint was the overall response rate (ORR); and secondary endpoints were duration of response (DoR), progression-free survival (PFS), safety, and pharmacokinetics. Patients were classified according to their best overall response after initiation of therapy. Proportions of patients in each response category (complete response [CR], partial response [PR], stable disease, or progressive disease) were summarized along with a two-sided binomial exact 95% confidence intervals (CIs) for the ORR.@*RESULTS@#A total of 102 patients were enrolled from 20 centers between August 6th, 2012, and June 18th, 2015. At the time of the primary analysis, the ORR was 73% (95% CI: 63%-81%) per Independent Review Committee (IRC) including 19% CR and 54% PR. With the follow-up period, the median DoR was 16.2 months by IRC and 13.4 months by investigator assessment; the median PFS was 18.6 months and 15.3 months, respectively. The most common non-hematologic adverse events (AEs) were gastrointestinal toxicity, pyrexia, and rash. Grade 3/4 neutropenia was reported in 76% of patients. Serious AEs were reported in 29 patients and five patients died during the study. Pharmacokinetic analysis indicated that the characteristics of bendamustine and its metabolites M3 and M4 were generally consistent with those reported for other ethnicities.@*CONCLUSION@#Bendamustine is an active and effective therapy in Chinese patients with relapsed, indolent B-cell NHL, with a comparable risk/benefit relationship to that reported in North American patients.@*CLINICAL TRIAL REGISTRATION@#ClinicalTrials.gov, No. NCT01596621; https://clinicaltrials.gov/ct2/show/NCT01596621.

ABSTRACT

Purpose@#Acute decompensated heart failure (ADHF) caused by ischemic heart disease is associated with higher mortality and requires immediate diagnosis. Recently, novel methods to diagnose non-ST elevation myocardial infarction (NSTEMI) using high-sensitivity cardiac troponin have been applied. We compared the clinical utility of high-sensitivity troponin I (hS-TnI), delta troponin I, and other traditional methods to diagnose NSTEMI in patients with ADHF. @*Materials and Methods@#This retrospective cross-sectional study was conducted to analyze patients with ADHF who underwent hS-TnI evaluation of 0–2-h protocol in our emergency department. Patients were grouped according to a diagnosis of NSTEMI. @*Results@#A total of 524 ADHF [ADHF with NSTEMI, n=109 (20.8%)] patients were enrolled in this analysis. The mean values of hS-TnI (ng/mL) in the ADHF with and without NSTEMI groups were 2.44±5.60 and 0.25±0.91, respectively. Multivariable analysis revealed that regional wall-motion abnormality, T-wave inversion/hyperacute T wave, and initial and delta hS-TnI were predictive factors for NSTEMI. Laboratory values related to cardiac biomarkers, including hS-TnI [odds ratio (OR) (95% confidence interval, CI): 2.18], and the delta hS-TnI [OR (95% CI): 1.55] were significant predictors of NSTEMI. Moreover, receiver operating characteristic analysis showed that the areas under receiver operating characteristic curves for electrocardiographic abnormalities, initial hS-TnI, and delta hS-TnI were 0.794, 0.802, and 0.773, respectively. @*Conclusion@#For diagnosis of suspected NSTEMI in patients with ADHF, initial hS-TnI assay has similar predictive value as ischemic changes on electrocardiogram and superior predictive value than delta hS-TnI calculated by the 0–2-h protocol.

ABSTRACT

Purpose@#There are no standard surgical treatments for open distal radius fractures (DRFs), and the fracture fixator is chosen by the surgeon’s own experience. This study compared the outcomes of open reduction and volar locking plating (OR VLP) between closed and open AO-OTA type C3 DRFs. @*Materials and Methods@#Patient data were retrospectively collected between January 2010 and December 2018. Only patients aged >18 years with AO-OTA C3 DRFs were included. After further exclusion, the patients with DRFs were divided into two groups: 13 patients with open DRFs in Group 1 and 203 patients with closed DRFs in Group 2. Data on the patient characteristics and treatment-related factors were further investigated. For the radiological evaluation, the radial height, volar height, and volar titling were measured based on the final plain radiography, and the union time was measured. The wristrange of motion (ROM), pain visual analogue scale score, and modified Mayo wrist score for function were measured at the final outpatient follow-up. Finally, the complications associated with OR VLP fixa-tion were investigated. @*Results@#In the demographic comparison, the patients with open fractures were older (mean age, 62years) than those with closed fractures (mean age, 57 years), without a statistically significant differ-ence. The patients with open DRFs had longer antibiotic therapy and hospital stay durations. Although they presented a higher radial inclination, with statistical significance, the clinical implication was low with a mean difference of 3°. No significant differences were observed for the remaining radiologicalparameters, wrist ROM, and functional scores. An open DRF did not increase the complication rates,including deep infection. @*Conclusion@#Depending on the expertise of the operating surgeon, the primary OR VLP fixation in open intra-articular comminuted DRF did not increase the incidence of deep infections and yielded similar outcomes to a closed intra-articular comminuted DRF.

ABSTRACT

Background@#The rupture of the central slip of an extensor tendon of a finger causes a boutonniere (or buttonhole) deformity, characterized by pathologic flexion at the proximal interphalangeal (PIP) joint and hyperextension at the distal interphalangeal (DIP) joint. Currently, there are no standard treatment guidelines for this deformity. This study aimed to report clinical results of surgery to correct chronic boutonniere deformity. @*Methods@#This retrospective case series was conducted between January 2010 and December 2018 and only 13 patients with trauma-induced chronic deformity were included. After excision of elongated scar tissue, a direct anatomic end-to-end repair using a loop suture technique with supplemental suture anchor augmentation was conducted. Total active motion was assessed before and after surgery and self-satisfaction scores were collected from phone surveys. @*Results@#All patients presented with Burton stage I deformities defined as supple and passively correctable joints. The initial mean extension lag of the PIP joint (43.5°) was improved by an average of 21.9° at the final follow-up (p < 0.001). The mean hyperextension of the DIP joint averaged 19.2° and improved by 0.8° flexion contracture (p < 0.001). The average total active motion was 220.4° (range, 160°–260°). Based on the Souter’s criteria, 69.2% (9/13) of the patients had good results. Only 1 patient reported fair outcome and 23.1% (3/13) reported poor outcome. The average Strickland formula score was 70 (range, 28.6–97.1). In total, 10 patients (77%) had excellent or good results. Of 10 patients contacted by phone, self-reported satisfaction score was very satisfied in 2, satisfied in 3, average in 3, poor in 1, and very poor in 1. Three patients reported a relapse of the deformity during range of motion exercises, 1 of whom underwent revision surgery. One patient complained of PIP joint flexion limitation, and 2 complained of DIP joint flexion limitation at final follow-up. @*Conclusions@#In chronic boutonniere deformity, central slip reconstruction with anchor suture augmentation can be an easily applicable surgical option, which offers fair to excellent outcome in 77% of the cases. The risk of residual extension lag and recurrence of deformity should be discussed prior to surgery.

ABSTRACT

Objective:To investigate the effects of levetiracetam on bone metabolism and thyroid hormone levels in children with epilepsy.Methods:A total of 20 children with epilepsy first diagnosed in our hospital from July 2016 to June 2017 were selected as the treatment group, the other 20 children who received physical examination in the same period were selected as the control group.The treatment group was given oral LEV monotherapy for 12 months.The changes of bone metabolism indexes[blood calcium, blood phosphorus, alkaline phosphatase activities, osteocalcin, parathyroid hormone, 25-(OH)D], bone mineral density(BMD)and serum thyroid hormone(triiodothyronine, tetraiodothyronine, free triiodothyronine, free thyroxine, thyroid stimulating hormone) in the control group and the treatment group were detected before, 6 and 12 months after medication.Results:(1)There were no statistically significant differences in bone metabolism indexes and BMD between the control group and the treatment group before medication( P>0.05). The differences showed no statistically significant in bone metabolism indexes and BMD among different time points of treatment group( P>0.05). (2)There were no significant differences in thyroid hormone levels between the control group and the treatment group before medication( P>0.05). There were no significant differences in thyroid hormone levels among different time points of treatment group ( P>0.05). Conclusion:Levetiracetam has no significant effects on bone metabolism and thyroid hormone level in epileptic children.

ABSTRACT

Objective:To study the effects of new antiepileptic drugs (AEDs), including Topiramate (TPM), Oxcarbazepine(OXC), Lamotrigine(LTG), and Levetiracetam (LEV) monotherapy on bone metabolism in children with epilepsy aged 4-12.Method:s One hundred and sixty children with epilepsy who were diagnosed for the first time at Shanxi Children′s Hospital from July 2016 to June 2017 were selected and given oral TPM (40 cases), OXC (40 cases), LTG (40 cases) and LEV (40 cases) respectively according to the type of seizure.The changes of bone mineral density (BMD) and bone metabolism indexes including serum calcium (Ca), phosphorus (P), alkaline phosphatase (ALP), osteocalcin (OC), parathyroid hormone (PTH), 25 hydroxyvitamin D [25-(OH)D] before treatment and at 3, 6 and 12 months after treatment were observed.Result:s (1) Bone metabolism indicators and BMD had no significant difference among groups before treatment (all P>0.05). (2) After 6 and 12 months of treatment in OXC group, Ca was lower than before treatment[2.38(0.08) mmol/L vs.2.47(0.17) mmol/L, 2.44(0.10) mmol/L vs.2.47(0.17) mmol/L], PTH was higher than before treatment[37.64(17.52) ng/L vs.34.23(20.53) ng/L, 40.74(16.15) ng/L vs.34.23(20.53) ng/L]; Ca in TPM group decreased after 6 and 12 months of treatment[2.40(0.11) mmol/L vs.2.42(0.10) mmol/L, 2.41(0.09) mmol/L vs.2.42(0.10) mmol/L], and the differences were statistically significant(all P<0.05). (3) After 6 and 12 months of treatment, Ca in the OXC group was lower than that in the LEV group[2.38(0.08) mmol/L vs.2.44(0.10) mmol/L, 2.44(0.10) mmol/L vs.2.44(0.12) mmol/L] and LTG group[2.38(0.08) mmol/L vs.2.44(0.13) mmol/L, 2.44(0.10) mmol/L vs.2.42(0.13) mmol/L], and PTH in the OXC group was higher than that in the LEV group[37.64(17.52) ng/L vs.36.52(20.71) ng/L, 40.74(16.15) ng/L vs.31.89(14.84) ng/L] and LTG group[37.64(17.52) ng/L vs.39.39(24.03) ng/L, 40.74(16.15) ng/L vs.33.01(12.20) ng/L], Ca in TPM group after 12 months of treatment was lower than that in the LEV group[2.41(0.09) mmol/L vs.2.44(0.12) mmol/L] and LTG group[2.41(0.09) mmol/L vs.2.42(0.13) mmol/L], and the differences were statistically significant(all P<0.05). Conclusions:In the new AEDs, LEV and OXC have no significant effect on bone metabolism.TPM may affect bone metabolism by reducing Ca in children with epilepsy, and OXC may cause the decrease of Ca and the increase of PTH, thereby leading to increased bone turnover in children with epilepsy.
