Aging biomarkers are a combination of biological parameters to(i)assess age-related changes,(ii)track the physiological aging process,and(iii)predict the transition into a pathological status.Although a broad spectrum of aging biomarkers has been developed,their potential uses and limitations remain poorly characterized.An immediate goal of biomarkers is to help us answer the following three fundamental questions in aging research:How old are we?Why do we get old?And how can we age slower?This review aims to address this need.Here,we summarize our current knowledge of biomarkers developed for cellular,organ,and organismal levels of aging,comprising six pillars:physiological characteristics,medical imaging,histological features,cellular alterations,molecular changes,and secretory factors.To fulfill all these requisites,we propose that aging biomarkers should qualify for being specific,systemic,and clinically relevant. 展开更多

AIM:To analyze whether high-intensity focused ultrasound(HIFU) ablation is an effective bridging therapy for patients with hepatocellular carcinoma(HCC).METHODS:From January 2007 to December 2010,49 consecutive HCC patients were listed for liver transplantation(UCSF criteria).The median waiting time for transplantation was 9.5 mo.Twenty-nine patients received transarterial chemoembolization(TACE) as a bringing therapy and 16 patients received no treatment before transplantation.Five patients received HIFU ablation as a bridging therapy.Another five patients with the same tumor staging(within the UCSF criteria) who received HIFU ablation but not on the transplant list were included for comparison.Patients were comparable in terms of Child-Pugh and model for end-stage liver disease scores,tumor size and number,and cause of cirrhosis.RESULTS:The HIFU group and TACE group showed no difference in terms of tumor size and tumor number.One patient in the HIFU group and no patient in the TACE group had gross ascites.The median hospital stay was 1 d(range,1-21 d) in the TACE group and two days(range,1-9 d) in the HIFU group(P < 0.000).No HIFU-related complication occurred.In the HIFU group,nine patients(90%) had complete response and one patient(10%) had partial response to the treatment.In the TACE group,only one patient(3%) had response to the treatment while 14 patients(48%) had stable disease and 14 patients(48%) had progressive disease(P = 0.00).Seven patients in the TACE group and no patient in the HIFU group dropped out from the transplant waiting list(P = 0.559).CONCLUSION:HIFU ablation is safe and effective in the treatment of HCC for patients with advanced cirrhosis.It may reduce the drop-out rate of liver transplant candidate. 展开更多

This review aims to provide a concise overview of the trauma management evolution in the past decade. 1) Trauma care priorities have incorporated staff protection against infection and early decision making in addition to the conventional ABCDE. 2) Five stratified levels for DAM have replaced the non-specific conventional Plans A & B. 3) CT scanning can be the tunnel to death for the hemodynamically unstable patient. 4) DPL has virtually been replaced by the FAST USG. 5) Direct whole-body MDCT provides rapid imaging diagnosis & expedites the definitive treatment but carries high radiation hazards. 6) The dynamic shock assessment by fluid resuscitation response provides more outcome-specific evaluation than the static blood volume loss model. 7) DCR comprising of permissive hypotension, hemostatic resuscitation & DCS aims to overcome the lethal triad of trauma. Early transfusion of blood components of FFP & platelet concentrates improves the outcome in massive blood transfusion. 8) DCS aims to rectify the deranged physiology and not to fully restore the damaged anatomy. 9) A pre-defined protocol for major pelvic fracture can be life-saving and the novel Pre-PPP (pre-peritoneal pelvic packing) may further reduce mortality coupled with the necessary TCAE. 10) Injury prevention is equally important if not more than the trauma resuscitation & operation. 展开更多

We use a combination of both algebraic and numerical techniques to construct a C-1-continuous, piecewise (m, n) rational epsilon-approximation of a real algebraic plane curve of degree d. At singular points we use the classical Weierstrass Preparation Theorem and Newton power series factorizations, based on the technique of Hensel lifting. These, together with modified rational Pade approximations, are used to efficiently construct locally approximate, rational parametric representations for all real branches of an algebraic plane curve. Besides singular points we obtain an adaptive selection of simple points about which the curve approximations yield a small number of pieces yet achieve C-1 continuity between pieces. The simpler cases of C-1 and C-0 continuity are also handled in a similar manner. The computation of singularity, the approximation error bounds and details of the implementation of these algorithms are also provided. 展开更多

BACKGROUND:Recurrence of hepatitis B virus(HBV) infection after liver transplantation can lead to graft loss and a reduction in long-term survival.The purpose of this review is to summarize the current therapeutic options for preventing HBV recurrence in liver transplant recipients.DATA SOURCES:Up to January 2013,studies that were published in MEDLINE and EMBASE on prevention of HBV recurrence after liver transplantation were reviewed.RESULTS:There have been remarkable advancements in the past two decades on the prevention of HBV recurrence after liver transplantation,from the discovery of hepatitis B immune globulin(HBIG) and lamivudine monotherapy to the combination therapy using HBIG and lamivudine.With the development of newer and stronger antiviral agents,the need for life-long HBIG is doubtful.With their low resistance profile,oral antiviral prophylaxis using these new agents alone is sufficient and is associated with excellent outcome.CONCLUSIONS:Restoration of host HBV immunity with adoptive immunity transfer and vaccination may represent the ultimate strategy to withdraw prophylactic treatment and to achieve a drug free regimen against HBV recurrence after liver transplantation. 展开更多

Objective The optimal antithrombotic regimen for patients on oral anticoagulation (OAC) after acute coronary syndrome (ACS) and percutaneous coronary intervention (PCI) remains debated. This study sought to evaluate the efficacy and safety of OAC plus clopidogrel with or without aspirin in a real-world setting. Methods We retrospectively analyzed data from an international, multi-center registry be- tween 2003 and 2014 (n = 15,401). Patients with ACS and receiving OAC after PCI were screened. The composite primary endpoint was 1-year all-cause death, re-infarction, or severe bleeding. Results The final analysis enrolled 642 patients including 62 patients (9.7%) with OAC and clopidogrel (dual therapy), and 580 patients (90.3%) with the combination of aspirin, OAC and clopidogrel (triple therapy). Pa- tients on triple therapy were more often female and were more likely to have comorbidities. There was no significant difference regarding the primary end point between dual therapy with triple therapy patients [17.74% vs. 17.24%; unadjusted hazard ratio (HR): 1.035; 95% confi- dence interval (CI): 0.556-1.929; adjusted HR: 1.026; 95% CI: 0.544-1.937]. However, the re-infarction rate was significantly higher in dual therapy than triple therapy patients (14.52% vs. 5.34%; unadjusted HR: 2.807; 95% CI: 1.329-5.928; adjusted HR: 2.333; 95% CI: 1.078-5.047). In addition, there was no difference between two regimes in all-cause death and severe bleeding. Conclusions In real-life patients with ACS following PCI and with an indication of OAC, triple therapy was not associated with an increased rate of adverse out- comes compared to dual therapy. Moreover, it decreased risk of re-infarction and did not increase risk of severe bleeding. 展开更多

Umbilical hernia occurs in 20% of the patients with liver cirrhosis complicated with ascites. Due to the enormous intraabdominal pressure secondary to the ascites, umbilical hernia in these patients has a tendency to enlarge rapidly and to complicate. The treatment of umbilical hernia in these patients is a surgical challenge. Ascites control is the mainstay to reduce hernia recurrence and postoperative complications, such as wound infection, evisceration, ascites drainage, and peritonitis. Intermittent paracentesis, temporary peritoneal dialysis catheter or transjugular intrahepatic portosystemic shunt may be necessary to control ascites. Hernia repair is indicated in patients in whom medical treatment is effective in controlling ascites. Patients who have a good perspective to be transplanted within 3-6 mo, herniorrhaphy should be performed during transplantation. Hernia repair with mesh is associated with lower recurrence rate, but with higher surgical site infection when compared to hernia correction with conventional fascial suture. There is no consensus on the best abdominal wall layer in which the mesh should be placed: Onlay, sublay, or underlay. Many studies have demonstrated several advantages of the laparoscopic umbilical herniorrhaphy in cirrhotic patients compared with open surgical treatment. 展开更多

The expression of the anti-apoptotic molecules Bcl-2 and transforming growth factor-beta 1 is known to confer protective effects on the cerebral ischemia-reperfusion injury.The current study investigated the expression levels of Bcl-2 and transforming growth factor-beta 1 in response to multiple pre-ischemia electro-acupuncture at acupoints Zusanli(ST36)and Fengchi(GB20) stimulation.Rats were divided into five groups:uninjured,control,non-acupoint,GB20 and ST36. Rats in the non-acupoint,GB20 and ST36 groups received 30 minutes(3 times or 18 times)of electro-acupuncture stimulation before experimental cerebral ischemia was induced.Bcl-2 and transforming growth factor-beta 1 were found to be significantly increased in the ST36 groups with either 3 or 18 electro-acupuncture treatments(P〈0.05).The production was higher with 18 electro-acupuncture treatments in the ST36 groups(P〈0.05).In the GB20 groups,significant increase was only observed in transforming growth factor-beta 1 with 18 electro-acupuncture treatments(P〈0.05).No significant elevation of the level of transforming growth factor-beta 1 was observed in the non-acupoint groups.However,the production of Bcl-2 increased with 18 treatments in the non-acupoint groups(P〈0.05).The data suggest that multiple pre-ischemia electro-acupuncture at ST36 was effective in conferring neuroprotective effect on the brain by means of upregulation of Bcl-2 and transforming growth factor-beta 1 and the effect was increase with the number of treatment. 展开更多

In order to reduce dropping out, different bridging therapies are employed. We report the use of high-intensity focused ultrasound ablation as a bridging therapy for a patient with hepatocellular carcinoma of stage two and an extremely low platelet count (20×10 9 /L). The ablation was successful. Blood tests showed that his liver function was similar before and after the treatment. No adhesion was encountered in the liver transplantation performed six months later. 展开更多
