1CrN活塞环涂层的摩擦学性能显示文摘以PVD方法在不锈钢渗氮活塞环基体上沉积了厚约 30μm的CrN涂层。采用 2种GF-3等级的全配方发动机油作为润滑剂,在SRV试验机上,对比了具有 /没有CrN涂层的不锈钢渗氮活塞环的摩擦学性能。试验结果表明,CrN涂层能使摩擦因数数较快的稳定且数值较低,同时活塞环及其对磨缸套的磨损量也大大降低,对磨缸套的磨损量减少了80%以上。SEM分析结果表明,由于CrN涂层具有较高的硬度和较低的表面粗糙度,可以降低磨粒磨损,且能使对磨的缸套试样较快地与之适配,从而促进了摩擦反应膜的形成和扩展,是摩擦因数和磨损量降低的主要原因。赵晚成 马亚军 李生华 金元生 王玉琮 Simon C Tung 2005润滑与密封2005,30,2:21
2Treatment of meniscal tears: An evidence based approach显示文摘Treatment options for meniscal tears fall into three broad categories;non-operative,meniscectomy or meniscal repair.Selecting the most appropriate treatment for a given patient involves both patient factors(e.g.,age,co-morbidities and compliance)and tear characteristics(e.g.,location of tear/age/reducibility of tear).There is evidence suggesting that degenerative tears in older patients without mechanical symptoms can be effectively treated non-operatively with a structured physical therapy programme as a first line.Even if these patients later require meniscectomy they will still achieve similar functional outcomes than if they had initially been treated surgically.Partial meniscectomy is suitable for symptomatic tears not amenable to repair,and can still preserve meniscal function especially when the peripheral meniscal rim is intact.Meniscal repair shows 80%success at 2 years and is more suitable in younger patients with reducible tears that are peripheral(e.g.,nearer the capsular attachment)and horizontal or longitudinal in nature.However,careful patient selection and repair technique is required with good compliance to post-operative rehabilitation,which often consists of bracing and non-weight bearing for 4-6 wk.Simon C Mordecai Nawfal Al-Hadithy Howard E Ware Chinmay M Gupte 2014World Journal of Orthopedics2014,5,3:18

5Stem cell treatment and cerebral palsy: Systemic review and meta-analysis显示文摘BACKGROUND Perinatal complications may result in life-long morbidities,among which cerebral palsy(CP)is the most severe motor disability.Once developed,CP is a nonprogressive disease with a prevalence of 1-2 per 1000 live births in developed countries.It demands an extensive and multidisciplinary care.Therefore,it is a challenge for our health system and a burden for patients and their families.Recently,stem cell therapy emerged as a promising treatment option and raised hope in patients and their families.AIM The aim is to evaluate the efficacy and safety of stem cell treatment in children with CP using a systematic review and meta-analysis METHODS We performed a systematic literature search on PubMed and EMBASE to find randomized controlled clinical trials(RCT)investigating the effect of stem cell transplantation in children with CP.After the review,we performed a randomeffects meta-analysis focusing on the change in gross motor function,which was quantified using the gross motor function measure.We calculated the pooled standardized mean differences of the 6-and/or 12-mo-outcome by the method of Cohen.We quantified the heterogeneity using the I-squared measure.RESULTS We identified a total of 8 RCT for a qualitative review.From the initially selected trials,5 met the criteria and were included in the meta-analysis.Patients’population ranged from 0.5 up to 35 years(n=282).We detected a significant improvement in the gross motor function with a pooled standard mean difference of 0.95(95%confidence interval:0.13-1.76)favoring the stem cell group and a high heterogeneity(I2=90.1%).Serious adverse events were rare and equally distributed among both intervention and control groups.CONCLUSION Stem cell therapy for CP compared with symptomatic standard care only,shows a significant positive effect on the gross motor function,although the magnitude of the improvement is limited.Short-term safety is present and further highquality RCTs are needed.Simone Eggenberger Céline Boucard Andreina Schoeberlein Raphael Guzman Andreas Limacher Daniel Surbek Martin Mueller 2019World Journal of Stem Cells2019,11,10:8

7血浆游离DNA水平增高可作为预测重型颅脑损伤患者死亡率的独立指标(英文)显示文摘Trauma is the leading cause of death under 45 years worldwide and up to 50% of trauma fatalities are due to brain injury.Prediction of outcome is one of the major problems associated with severe TBI and research efforts have focused on the investigation of biomarkers with prognostic value following TBI. Therefore,our aim was to investigate whether cell-free DNA concentrations correlated to short-term primary outcome( survivor or death) and GCS scores following severe TBI. A total of 188 victims of severe TBI were enrolled in this prospective study,outcome variables comprised: survival and neurological assessment using the GCS at ICU discharge. Control blood samples were obtained from 25 healthy volunteers. Peripheral venous blood was collected at admission in the ICU. Plasma DNA was measured using a real-time quantitative PCR assay for the β-globin gene. There was correlation between higher DNA levels and both fatal outcome and lower hospital admission GCS scores. Plasma DNA concentrations at the chosen cut- off point( ≥171,381 kilogenomesequivalents /L) predicted mortality with a specificity of 90% and a sensitivity of 43%. Logistic regression analysis showed that elevated plasma DNA levels were independently associated with death( P < 0. 001). In conclusion,high cell-free DNA concentration was a predictor of short-term mortality following severe TBI.Rodrigues Filho EM1 Simon D Ikuta N Klovan C Dannebrock F de Oliveira CO Regner A 2014中华神经外科疾病研究杂志2014,13,3:6

9pRB expression in esophageal mucosa of individuals at high risk for squamous cell carcinoma of the esophagus显示文摘AIM: To investigate the pRb expression in a large group of patients with history of chronic exposure to the main risk factors for development of squamous cell carcinoma of the esophagus. METHODS: One hundred and seventy asymptomatic individuals at high risk for esophageal squamous cell carcinoma (consumption of more than 80 g of ethanol and 10 cigarettes/d for at least 10 years) underwent upper gastrointestinal endoscopy with biopsies of the esophageal mucosa. As a control group, specimens of esophageal mucosa obtained from 20 healthy subjects were also studied. Immunohistochemical assessment of the tissues was performed using a monoclonal antibody anti-pRB protein. RESULTS: Absence of the pRB staining, indicating loss of RB function, was observed in 33 (19.4%) of the individuals at risk for esophageal cancer, but in none of the healthy controls (P < 0.02). Loss of pRb expression increased in a stepwise fashion according to the severity of the histological findings (P < 0.005): normal mucosa (11/97 or 11.3%), chronic esophagitis (17/60 or 28.3%), low-grade dysplasia (3/10 or 30%), high-grade dysplasia 1/2 or 50%) and squamous cell carcinoma (1/1 or 100%). CONCLUSION: Our findings suggest that abnormal expression of the pRB protein may be implicated in the process of esophageal carcinogenesis. Additional studies are warranted to define the role of the pRBprotein as a biomarker for development of esophageal squamous cell carcinoma in individuals at high risk for this malignancy.Simone S Contu Paulo C Contu Daniel C Damin Renato B Fagundes Fabiano Bevilacqua Aline S Rosa Joo C Prolla Luis F Moreira 2007World Journal of Gastroenterology2007,13,11:5
10Colorectal liver metastases: Current management and future perspectives显示文摘The liver is the commonest site of metastatic disease for patients with colorectal cancer,with at least 25%developing colorectal liver metastases(CRLM)during the course of their illness.The management of CRLM has evolved into a complex field requiring input from experienced members of a multi-disciplinary team involving radiology(cross sectional,nuclear medicine and interventional),Oncology,Liver surgery,Colorectal surgery,and Histopathology.Patient management is based on assessment of sophisticated clinical,radiological and biomarker information.Despite incomplete evidence in this very heterogeneous patient group,maximising resection of CRLM using all available techniques remains a key objective and provides the best chance of long-term survival and cure.To this end,liver resection is maximised by the use of downsizing chemotherapy,optimisation of liver remnant by portal vein embolization,associating liver partition and portal vein ligation for staged hepatectomy,and combining resection with ablation,in the context of improvements in the functional assessment of the future remnant liver.Liver resection may safely be carried out laparoscopically or open,and synchronously with,or before,colorectal surgery in selected patients.For unresectable patients,treatment options including systemic chemotherapy,targeted biological agents,intraarterial infusion or bead delivered chemotherapy,tumour ablation,stereotactic radiotherapy,and selective internal radiotherapy contribute to improve survival and may convert initially unresectable patients to operability.Currently evolving areas include biomarker characterisation of tumours,the development of novel systemic agents targeting specific oncogenic pathways,and the potential reemergence of radical surgical options such as liver transplantation.Jack Martin Angelica Petrillo Elizabeth C Smyth Nadeem Shaida Samir Khwaja HK Cheow Adam Duckworth Paula Heister Raaj Praseedom Asif Jah Anita Balakrishnan Simon Harper Siong Liau Vasilis Kosmoliaptsis Emmanuel Huguet 2020World Journal of Clinical Oncology2020,11,10:5
11Upper esophageal sphincter abnormalities are strongly predictive of treatment response in patients with achalasia显示文摘AIM: To investigate the relationship between upper esophageal sphincter abnormalities achalasia treatment METHODS: We performed a retrospective study of 41 consecutive patients referred for high resolution esophageal manometry with a final manometric diagnosis of achalasia. Patients were sub-divided by presence or absence of Upper esophageal sphincter(UES) abnormality, and clinical and manometric profiles were compared.Correlation between UES abnormality and sub-type(i.e.,hypertensive, hypotensive or impaired relaxation) and a number of variables, including qualitative treatment response, achalasia sub-type, co-morbid medical illness,psychiatric illness, surgical history, dominant presentingsymptom, treatment type, age and gender were also evaluated.RESULTS: Among all 41 patients, 24(58.54%) had a UES abnormality present. There were no significant differences between the groups in terms of age, gender or any other clinical or demographic profiles. Among those with UES abnormalities, the majority were either hypertensive(41.67%) or had impaired relaxation(37.5%) as compared to hypotensive(20.83%), although this did not reach statistical significance(P = 0.42). There was no specific association between treatment response and treatment type received; however, there was a significant association between UES abnormalities and treatment response. In patients with achalasia and concomitant UES abnormalities, 87.5% had poor treatment response, while only 12.5% had favorable response. In contrast, in patients with achalasia and no UES abnormalities, the majority(78.57%) had good treatment response, as compared to 21.43% with poor treatment response(P = 0.0001). After controlling for achalasia sub-type, those with UES abnormality had 26 times greater odds of poor treatment response than those with no UES abnormality(P = 0.009). Similarly, after controlling for treatment type, those with UES abnormality had 13.9 times greater odds of poor treatment response compared to those with no UES abnormality(P = 0.017).CONCLUSION: The presence of UES abnormalities in patients with achalasia significantly predicted poorer treatment response as compared to those with normal UES function.Simon C Mathews Maria Ciarleglio Yamile Haito Chavez John O Clarke Ellen Stein Bani Chander Roland 2014World Journal of Clinical Cases2014,2,9:5
12Machine perfusion of the liver: Which is the best technique to mitigate ischaemia-reperfusion injury?显示文摘Longstanding research describes the mechanisms whereby the restoration of blood flow and reoxygenation(reperfusion) aggravates the ischaemic injury caused by a period of anoxia to a donor liver. This phenomenon, called ischaemia-reperfusion injury(IRI), leads to parenchymal cell death,microcirculatory failure, and inflammatory immune response. Clinically, IRI is the main factor responsible for the occurrence of posttransplant graft dysfunction and ischaemic-type biliary lesions. While extended criteria donor livers are more vulnerable to IRI, their utilisation is required to address the shortfall in donor organs. Thus, the mitigation of IRI should drive the setting of a new benchmark for marginal organ preservation. Herein, strategies incorporating different modalities of machine perfusion of the liver to alleviate IRI are discussed in conjunction with advantages and disadvantages of individual protocols.Techniques leading to reperfusion of the liver during machine perfusion(in situ normothermic regional perfusion and ex situ normothermic machine perfusion)may mitigate IRI by shortening the ischaemic period of the organs. This benefit potentially escalates from the minimum level, obtained following just partial alleviation of the ischaemic period, to the maximum level, which can be potentially achieved with ischaemia-free organ transplantation. Techniques that do not lead to reperfusion of the liver during machine perfusion(hypothermic,subnormothermic, and controlled-oxygenated rewarming) optimise mitochondrial oxidative function and replenish cellular energy stores, thereby lowering reactive oxygen species production as well as the activation ofdownstream inflammatory pathways during reperfusion. Further mechanistic insights into IRI may guide the development of donor-specific protocols of machine perfusion on the basis of the limitations of individual categories of extended criteria donor organs.Yuri L Boteon Simon C Afford 2019World Journal of Transplantation2019,9,1:5
13Recurrent ectopic pancreatitis of the jejunum and mesentery over a 30-year period显示文摘BACKGROUND:Ectopic pancreas is defined as pancreatic tissue found outside its usual anatomical position,with no ductal or vascular communication with the native pancreas. We describe a case of ectopic pancreas of the small bowel and mesentery causing recurrent episodes of pancreatitis, initially suspected on computed tomography(CT)and magnetic resonance cholangiopancreatography(MRCP),and confirmed on histological review of the resection. METHODS:A 67-year-old woman presented with clinical symptoms and biochemical evidence of pancreatitis.She had similar episodes over the past 30 years with unrevealing investigations,and was concluded to have idiopathic pancreatitis. She underwent CT and MRCP,with findings suggestive of ectopic pancreas,a diagnosis confirmed on histology of the resection. RESULTS:MRCP identified a mass in the proximal small bowel mesentery isointense to the native pancreas,with a small duct draining into a proximal jejunal loop.The resected specimen consisted of normal parenchyma with lobulated acinar tissue with scattered islets of Langerhans,an occasional ductular structure,and admixed areas of adipose tissue.The patient remained asymptomatic with normal biochemistry six months post-operatively. CONCLUSION:In an individual with abdominal pain,elevated serum amylase/lipase,but imaging findings of a normal native pancreas,ectopic pancreatitis should be considered,and can be evaluated by CT and MRCP.John CT Wong Charlotte Robinson Edward C Jones Alison Harris Charles Zwirewich Robert Wakefield Richard K Simons Eric M Yoshida 2011Hepatobiliary & Pancreatic Diseases International2011,10,2:4

15Mechanisms of autophagy activation in endothelial cell and their targeting during normothermic machine liver perfusion显示文摘Ischaemia-reperfusion injury(IRI) is the leading cause of injury seen in the liver following transplantation. IRI also causes injury following liver surgery and haemodynamic shock. The first cells within the liver to be injured by IRI are the liver sinusoidal endothelial cells(LSEC). Recent evidence suggests that LSEC coordinate and regulates the livers response to a variety of injuries. It is becoming increasingly apparent that the cyto-protective cellular process of autophagy is a key regulator of IRI. In particular LSEC autophagy may be an essential gatekeeper to the development of IRI. The recent availability of liver perfusion devices has allowed for the therapeutic targeting of autophagy to reduce IRI. In particular normothermic machine liver perfusion(NMP-L) allow the delivery of pharmacological agents to donor livers whilst maintaining physiological temperature and hepatic flow rates. In this review we summarise the current understanding of endothelial autophagy and how this may be manipulated during NMP-L to reduce liver IRI.Yuri L Boteon Richard Laing Hynek Mergental Gary M Reynolds Darius F Mirza Simon C Afford Ricky H Bhogal 2017World Journal of Gastroenterology2017,23,48:4

17Machine learning models compared to existing criteria for noninvasive prediction of endoscopic retrograde cholangiopancreatography-confirmed choledocholithiasis显示文摘Background and aims:Noninvasive predictors of choledocholithiasis have generally exhibited marginal performance characteristics.We aimed to identify noninvasive independent predictors of endoscopic retrograde cholangiopancreatography(ERCP)-confirmed choledocholithiasis and accordingly developed predictive machine learning models(MLMs).Methods:Clinical data of consecutive patients undergoing first-ever ERCP for suspected chol-edocholithiasis from 2015 to 2019 were abstracted from a prospectively-maintained database.Multiple logistic regression was used to identify predictors of ERCP-confirmed choledocholithiasis.MLMs were then trained to predict ERCP-confirmed choledocholithiasis using pre-ERCP ultrasound(US)imaging only as well as using all available noninvasive imaging(US,computed tomography,and/or magnetic reso-nance cholangiopancreatography).The diagnostic performance of American Society for Gastrointestinal Endoscopy(ASGE)“high-likelihood”criteria was compared to MLMs.Results:We identified 270 patients(mean age 46 years,62.2%female,73.7%Hispanic/Latino,59%with noninvasive imaging positive for choledocholithiasis)with native papilla who underwent ERCP for suspected choledocholithiasis,of whom 230(85.2%)were found to have ERCP-confirmed chol-edocholithiasis.Logistic regression identified choledocholithiasis on noninvasive imaging(odds ratio(OR)¼3.045,P¼0.004)and common bile duct(CBD)diameter on noninvasive imaging(OR¼1.157,P¼0.011)as predictors of ERCP-confirmed choledocholithiasis.Among the various MLMs trained,the random forest-based MLM performed best;sensitivity was 61.4%and 77.3%and specificity was 100%and 75.0%,using US-only and using all available imaging,respectively.ASGE high-likelihood criteria demonstrated sensitivity of 90.9%and specificity of 25.0%;using cut-points achieving this specificity,MLMs achieved sensitivity up to 97.7%.Conclusions:MLMs using age,sex,race/ethnicity,presence of diabetes,fever,body mass index(BMI),total bilirubin,maximum CBD diameter,and choledocholithiasis on pre-ERCP noninvasive imaging predict ERCP-confirmed choledocholithiasis with good sensitivity and specificity and outperform the ASGE criteria for patients with suspected choledocholithiasis.Camellia Dalai John M Azizian Harry Trieu Anand Rajan Formosa C Chen Tien Dong Simon W Beaven James H.Tabibian 2021Liver Research2021,5,4:3

19A family study of endophenotypes for psychosis within an early intervention programme in Hong Kong: Rationale and preliminary findings显示文摘The study of endophenotypes may be a viable strategy to tackle the genetic complexity and phenotypic heterogeneity of psychosis, but this research direction is relatively under-developed in China as compared to Western countries. We have recently initiated one of the first family studies of endophenotypes for psychosis in China. Patients entering an established early psychosis intervention service are recruited into this research project for phenotyping, endophenotyping and genotyping. At the endophenotypic level, four domains (neurological soft signs, neurocognition of prospective memory, social cognition of facial emotion recognition, and affective cognition of anticipatory and consummatory pleasure) are studied in the sample of patients with psychosis and their unaffected siblings. This article illustrates the benefit of a research-oriented clinical programme and its findings based on the data collected as of early 2011.LUI Simon S Y SHAM Pak CHAN Raymond C K CHEUNG Eric F C 2011Chinese Science Bulletin2011,56,32:2
