Despite ongoing research and new drug treatments, abdominal distension within 24 h postoperatively occurs in 8%–28% of all surgeries. We aim to analyze the effectiveness of preventing PGD by preoperatively stimulating Neiguan（PC6）, Zusanli（ST36） and Shangjuxu（ST37） bilaterally twice a day compared with sham-acupuncture treatment and standard treatment.METHODS AND DESIGN： This is a single-center, prospective practical randomized controlled trial. All groups will be given standard treatments. Patients undergoing vascular surgery under GA will be included from the Vascular Surgery Unit in West China Hospital of Sichuan University, China, and divided into three groups. The experimental group will receive routine treatments and acupuncture at PC6, ST36 and ST37 bilaterally with electrical stimulation twice a day for 20 min preoperatively. The sham-acupuncture group will receive pseudo-electroacupuncture at sham acupoints of PC6, ST36 and ST37, which are 1 cun away from the real acupoints. The routine-treatment group will not receive electroacupuncture. The outcomes include the incidence of abdominal distention, abdominal circumference, the degree of abdominal distension, the fi rst time of fl atus and defecation, and hospitalization duration. DISCUSSION： The results from this study will demonstrate whether preoperative electroacupuncture is an effective method for the prevention of PGD in patients undergoing vascular surgery under GA. This study may also provide a standardized acupuncture treatment for reduction of PGD. TRIAL REGISTRATION： This study is registered with the Chinese Clinical Trial Registry： Chi CTR-TRC-13003649.展开更多

Methods A literature search was performed for basic science studies, clinical studies and major practice guidelines on the subject of diastolic dysfunction and diastolic heart failure. Important findings were analyzed and correlated with regard to clinical relevance. Results Left ventricular diastolic dysfunction appears to compromise exercise tolerance and is believed to contribute to the pathophysiology in patients with diastolic heart failure. In the clinical setting, however, oftentimes no clear distinction is made between echocardiographically diagnosed diastolic dysfunction and diastolic heart failure, and adequate treatment recommendations are sparse and aimed to prevent worsening and progression of clinical symptoms. To date, there is a lack of high powered trials assessing the possible progression rate from echocardiographically diagnosed diastolic dysfunction to the clinical diagnosis of diastolic heart failure. Furthermore, there are no solid indices to assess the degree of severity of diastolic dysfunction or its progression. Pure right ventricular diastolic dysfunction appears to be even less understood and under-recognized, although it may play a role in the development of both right and left heart failure. Currently there are few but interesting data on the possible interaction between ventricles with diastolic dysfunction and the overall affect on the development of heart failure. Conclusions The timeline and progression of diastolic dysfunction to diastolic heart failure have not been well established and warrant further investigation.展开更多

文摘In this editorial,we comment on three articles published in a recent issue of World Journal of Gastroenterology.There is a pressing need for new research on autophagy's role in gastrointestinal(GI)disorders,and also novel insights into some liver conditions,such as metabolic dysfunction-associated fatty liver disease(MAFLD)and acute liver failure(ALF).Despite advancements,understanding autophagy's intricate mechanisms and implications in these diseases remains incomplete.Moreover,MAFLD's pathogenesis,encompassing hepatic steatosis and metabolic dysregulation,require further elucidation.Similarly,the mechanisms underlying ALF,a severe hepatic dysfunction,are poorly understood.Innovative studies exploring the interplay between autophagy and GI disorders,as well as defined mechanisms of MAFLD and ALF,are crucial for identifying therapeutic targets and enhancing diagnostic and treatment strategies to mitigate the global burden of these diseases.

文摘BACKGROUND Parkinson's disease(PD)-a progressive neurodegenerative disorder-is characterized by motor and gastrointestinal dysfunction.The exploration of novel therapeutic strategies for PD is vital.AIM To investigate the potential mechanism of action of rhapontin-a natural compound with known antioxidant and anti-inflammatory properties-in the context of PD.METHODS Network pharmacology was used to predict the targets and mechanisms of action of rhapontin in PD.Behavioral tests and tyrosine hydroxylase immunofluorescence analysis were used to assess the effect of rhapontin on symptoms and pathology in MPTP-induced mice.Interleukin(IL)-6,IL-1β,tumor necrosis factor(TNF)-α,and IL-10 levels in tissues were measured using an enzyme-linked immunosorbent assay(ELISA).Additionally,nuclear factor erythroid 2-related factor 2(NRF2)activation was confirmed using western blotting.RESULTS NRF2 was predicted to be the key transcription factor underlying the therapeutic effects of rhapontin in PD,and its anti-PD action may be associated with its antiinflammatory and antioxidant properties.Rhapontin ameliorated the loss of dopaminergic neurons and gastrointestinal dysfunction in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine(MPTP)-induced mice by activating NRF2.Additio-nally,rhapontin treatment significantly decreased pro-inflammatory cytokines(IL-6,TNF-α,IL-1β)in the substantia nigra,striatum,and colon,whereas it increased anti-inflammatory cytokine(IL-10)levels only in the colon,indicating the involvement of gut–brain axis in its neuroprotective potential.Finally,NRF2 was identified as a key transcription factor activated by rhapontin,particularly in the colon.CONCLUSION We elucidated the effects of rhapontin in MPTP-induced PD mouse models using a combination of network pharmacology analysis,behavioral assessments,immunofluorescence,ELISA,and Western blotting.Our findings revealed the multifaceted role of rhapontin in ameliorating PD through its anti-inflammatory and antioxidant properties,particularly by activating NRF2,paving the way for future research into targeted therapies for PD.

文摘AIM:To report preliminary results of the efficacy and safety of sunitinib in the management of Taiwan Residents gastrointestinal stromal tumors (GIST) patients facing imatinib mesylate (IM) intolerance or failure.METHODS:Between 2001 and May 2010,199 Taiwan Residents patients with metastatic GIST were treated at Chang Gung Memorial Hospital.Among them,23 (11.6%) patients receiving sunitinib were investigated.RESULTS:Sixteen male and 7 female patients with a median age of 59 years (range:24-83 years) received sunitinib.Twenty-two GIST patients changed to sunitinib because of IM failure and 1 because of intolerance.The median duration of sunitinib administration was 6.0 mo (range:2-29 mo).The clinical benefit was 65.2% [2 complete response (CR),4 partial response (PR),and 9 stationary disease (SD);15/23].In 12 patients harboring mutations of the kit gene at exon 11,the clinical benefit rate (CR,PR,and SD) was 75.0% and 6 patients with tumors containing kit exon 9 mutations had a clinical benefit of 50.0% (not significant,P=0.344).The progression free survival (PFS) and overall survival (OS) did not differ between patients whose GISTs had wild type,KIT exon 9,or KIT exon 11 mutations.Hand-foot syndrome was the most common cause of grade Ⅲ adverse effect (26.1%),followed by anemia (17.4%),and neutropenia (13.0%).During the median 7.5-mo follow-up after sunitinib use,the median PFS and OS of these 23 GIST patients after sunitinib treatment were 8.4 and 14.1 mo,respectively.CONCLUSION:Sunitinib appears to be an effective treatment for Taiwan Residents with IM-resistant/intolerant GISTs and induced a sustained clinical benefit in more than 50% of Taiwan Residents advanced GIST patients.
文摘BACKGROUND： Postoperative gastrointestinal dysfunction（PGD） is one of the most common complications following major surgeries under general anesthesia（GA）. Despite ongoing research and new drug treatments, abdominal distension within 24 h postoperatively occurs in 8%–28% of all surgeries. We aim to analyze the effectiveness of preventing PGD by preoperatively stimulating Neiguan（PC6）, Zusanli（ST36） and Shangjuxu（ST37） bilaterally twice a day compared with sham-acupuncture treatment and standard treatment.METHODS AND DESIGN： This is a single-center, prospective practical randomized controlled trial. All groups will be given standard treatments. Patients undergoing vascular surgery under GA will be included from the Vascular Surgery Unit in West China Hospital of Sichuan University, China, and divided into three groups. The experimental group will receive routine treatments and acupuncture at PC6, ST36 and ST37 bilaterally with electrical stimulation twice a day for 20 min preoperatively. The sham-acupuncture group will receive pseudo-electroacupuncture at sham acupoints of PC6, ST36 and ST37, which are 1 cun away from the real acupoints. The routine-treatment group will not receive electroacupuncture. The outcomes include the incidence of abdominal distention, abdominal circumference, the degree of abdominal distension, the fi rst time of fl atus and defecation, and hospitalization duration. DISCUSSION： The results from this study will demonstrate whether preoperative electroacupuncture is an effective method for the prevention of PGD in patients undergoing vascular surgery under GA. This study may also provide a standardized acupuncture treatment for reduction of PGD. TRIAL REGISTRATION： This study is registered with the Chinese Clinical Trial Registry： Chi CTR-TRC-13003649.

文摘BACKGROUND The prognosis of critically ill patients is closely linked to their gastrointestinal(GI)function.The acute GI injury(AGI)grading system,established in 2012,is extensively utilized to evaluate GI dysfunction and forecast outcomes in clinical settings.In 2021,the GI dysfunction score(GIDS)was developed,building on the AGI grading system,to enhance the accuracy of GI dysfunction severity assessment,improve prognostic predictions,reduce subjectivity,and increase reproducibility.AIM To compare the predictive capabilities of GIDS and the AGI grading system for 28-day mortality in critically ill patients.METHODS A retrospective study was conducted at the general intensive care unit(ICU)of a regional university hospital.All data were collected during the first week of ICU admission.The primary outcome was 28-day mortality.Multivariable logistic regression analyzed whether GIDS and AGI grade were independent risk factors for 28-day mortality.The predictive abilities of GIDS and AGI grade were compared using the receiver operating characteristic curve,with DeLong’s test assessing differences between the curves’areas.RESULTS The incidence of AGI in the first week of ICU admission was 92.13%.There were 85 deaths(47.75%)within 28 days of ICU admission.There was no initial 24-hour difference in GIDS between the non-survival and survival groups.Both GIDS(OR 2.01,95%CI:1.25-3.24;P=0.004)and AGI grade(OR 1.94,95%CI:1.12-3.38;P=0.019)were independent predictors of 28-day mortality.No significant difference was found between the predictive accuracy of GIDS and AGI grade for 28-day mortality during the first week of ICU admission(Z=-0.26,P=0.794).CONCLUSION GIDS within the first 24 hours was an unreliable predictor of 28-day mortality.The predictive accuracy for 28-day mortality from both systems during the first week was comparable.
文摘BACKGROUND Chronic heart failure(CHF)is a complex syndrome characterized by a progressive reduction of the left ventricular(LV)contractility,low exercise tolerance,and increased mortality and morbidity.Diastolic dysfunction(DD)of the LV,is a keystone in the pathophysiology of CHF and plays a major role in the progression of most cardiac diseases.Also,it is well estimated that exercise training induces several beneficial effects on patients with CHF.AIM To evaluate the impact of a cardiac rehabilitation program on the DD and LV ejection fraction(EF)in patients with CHF.METHODS Thirty-two stable patients with CHF(age:56±10 years,EF:32%±8%,88%men)participated in an exercise rehabilitation program.They were randomly assigned to aerobic exercise(AER)or combined aerobic and strength training(COM),based on age and peak oxygen uptake,as stratified randomization criteria.Before and after the program,they underwent a symptom-limited maximal cardiopulmonary exercise testing(CPET)and serial echocardiography evaluation to evaluate peak oxygen uptake(VO2peak),peak workload(Wpeak),DD grade,right ventricular systolic pressure(RVSP),and EF.RESULTS The whole cohort improved VO2peak,and Wpeak,as well as DD grade(P<0.05).Overall,9 patients(28.1%)improved DD grade,while 23(71.9%)remained at the same DD grade;this was a significant difference,considering DD grade at baseline(P<0.05).In addition,the whole cohort improved RVSP and EF(P<0.05).Not any between-group differences were observed in the variables assessed(P>0.05).CONCLUSION Exercise rehabilitation improves indices of diastolic and systolic dysfunction.Exercise protocol was not observed to affect outcomes.These results need to be further investigated in larger samples.
文摘Coronavirus disease 2019(COVID-19)caused by the novel severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)has become a major global public health event,resulting in a significant social and economic burden.Although COVID-19 was initially characterized as an upper respiratory and pulmonary infection,recent evidence suggests that it is a complex disease including gastrointestinal symptoms,such as diarrhea,nausea,and vomiting.Moreover,it remains unclear whether the gastrointestinal symptoms are caused by direct infection of the gastrointestinal tract by SARS-CoV-2 or are the result of systemic immune activation and subsequent dysregulation of homeostatic mechanisms.This review provides a brief overview of the mechanisms by which SARS-CoV-2 disrupts the integrity of the gastrointestinal barrier including the mechanical barrier,chemical barrier,microbial barrier,and immune barrier.

文摘Background:Data on severe and extensive burns in China are limited,as is data on the prevalence of a range of related gastrointestinal(GI)disorders[such as stress ulcers,delayed defecation,opioid-related bowel immotility,and abdominal compartment syndrome(ACS)].We present a multicentre analysis of coincident GI dysfunction and its effect on burn-related mortality.Methods:This retrospective analysis was conducted on patients with severe[≥20%total burn surface area(TBSA)]and extensive(>50%TBSA or>25%full-thickness TBSA)burns admitted to three university teaching institutions in China between January 1,2011 and December 31,2020.Both 30-and 90-day mortality were assessed by collating demographic data,burn causes,admission TBSA,%full-thickness TBSA,Baux score,Abbreviated Burn Severity Index(ABSI)score,and Sequential Organ Failure Assessment(SOFA)score,shock at admission and the presence of an inhalation injury.GI dysfunction included abdominal distension,nausea/vomiting,diarrhoea/constipation,GI ulcer/haemorrhage,paralytic ileus,feeding intolerance and ACS.Surgeries,length of intensive care unit(ICU)stay,pain control[in morphine milligram equivalents(MME)]and overall length of hospital stay(LOHS)were recorded.Results:We analyzed 328 patients[75.6%male,mean age:(41.6±13.6)years]with a median TBSA of 62.0%(41.0%–80.0%);256(78.0%)patients presented with extensive burns.The 90-day mortality was 23.2%(76/328),with 64(84.2%)of these deaths occurring within 30 d and 25(32.9%)occurring within 7 d.GI dysfunction was experienced by 45.4%of patients and had a significant effect on 90-day mortality[odds ratio(OR)=14.070,95%confidence interval(CI)5.886–38.290,P<0.001].Multivariate analysis showed that GI dysfunction was associated with admission SOFA score and%full-thickness TBSA.Overall,88.2%(67/76)of deceased patients had GI dysfunction[hazard ratio(HR)for death of GI dysfunction=5.951],with a survival advantage for functional disorders(diarrhoea,constipation,or nausea/vomiting)over GI ulcer/haemorrhage(P<0.001).Conclusion:Patients with severe burns have an unfavourable prognosis,as nearly one-fifth died within 90 d.Half of our patients had comorbidities related to GI dysfunction,among which GI ulcers and haemorrhages were independently correlated with 90-day mortality.More attention should be given to severe burn patients with GI dysfunction.
文摘OBJECTIVE To assess the role of beta-blockers(BB)in patients with chronic kidney disease(CKD)aged≥75 years.METHODS AND RESULTS From January 2008 to July 2014,we included 390 consecutive patients≥75 years of age with ejection fraction≤35%and glomerular filtration rate(GFR)≤60 m L/min per 1.73 m^2.We analyzed the relationship between treatment with BB and mortality or cardiovascular events.The mean age of our population was 82.6±4.1 years.Mean ejection fraction was 27.9%±6.5%.GFR was 60-45 m L/min per 1.73 m^2 in 50.3%of patients,45-30 m L/min per 1.73 m^2 in 37.4%,and<30 m L/min per 1.73 m^2 in 12.3%.At the conclusion of follow-up,67.4%of patients were receiving BB.The median follow-up was28.04(IR:19.41-36.67)months.During the study period,211 patients(54.1%)died and 257(65.9%)had a major cardiovascular event(death or hospitalization for heart failure).BB use was significantly associated with a reduced risk of death(HR=0.51,95%CI:0.35-0.74;P<0.001).Patients receiving BB consistently showed a reduced risk of death across the different stages of CKD:stage IIIa(GFR=30-45 m L/min per 1.73 m^2;HR=0.47,95%CI:0.26-0.86,P<0.0001),stage IIIb(GFR 30-45 m L/min per 1.73 m^2;HR=0.55,95%CI:0.26-1.06,P=0.007),and stages IV and V(GFR<30 m L/min per 1.73 m~2;HR=0.29,95%CI:0.11-0.76;P=0.047).CONCLUSIONS The use of BB in elderly patients with HFr EF and renal impairment was associated with a better prognosis.Use of BB should be encouraged when possible.

文摘BACKGROUND It is common for severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection to occur in the gastrointestinal tract,which can present itself as an initial symptom.The severity of coronavirus disease 2019(COVID-19)is often reflected in the prevalence of gastrointestinal symptoms.COVID-19 can damage the nerve supply to the digestive system,leading to gastrointestinal autonomic dysfunction.There is still much to learn about how COVID-19 affects the autonomic nervous system and the gastrointestinal tract.AIM To thoroughly explore the epidemiology and clinical aspects of COVID-19-induced gastrointestinal autonomic dysfunction,including its manifestations,potential mechanisms,diagnosis,differential diagnosis,impact on quality of life,prognosis,and management and prevention strategies.METHODS We conducted a thorough systematic search across various databases and performed an extensive literature review.Our review encompassed 113 studies published in English from January 2000 to April 18,2023.RESULTS According to most of the literature,gastrointestinal autonomic dysfunction can seriously affect a patient's quality of life and ultimate prognosis.Numerous factors can influence gastrointestinal autonomic nervous functions.Studies have shown that SARS-CoV-2 has a well-documented affinity for both neural and gastrointestinal tissues,and the virus can produce various gastrointestinal symptoms by reaching neural tissues through different pathways.These symptoms include anorexia,dysgeusia,heartburn,belching,chest pain,regurgitation,vomiting,epigastric burn,diarrhea,abdominal pain,bloating,irregular bowel movements,and constipation.Diarrhea is the most prevalent symptom,followed by anorexia,nausea,vomiting,and abdominal pain.Although COVID-19 vaccination may rarely induce autonomic dysfunction and gastrointestinal symptoms,COVID-19-induced autonomic effects significantly impact the patient's condition,general health,prognosis,and quality of life.Early diagnosis and proper recognition are crucial for improving outcomes.It is important to consider the differential diagnosis,as these symptoms may be induced by diseases other than COVID-19-induced autonomic dysfunction.Treating this dysfunction can be a challenging task.CONCLUSION To ensure the best possible outcomes for COVID-19 patients,it is essential to take a multidisciplinary approach involving providing supportive care,treating the underlying infection,managing dysfunction,monitoring for complications,and offering nutritional support.Close monitoring of the patient's condition is crucial,and prompt intervention should be taken if necessary.Furthermore,conducting thorough research on the gastrointestinal autonomic dysfunction caused by COVID-19 is vital to manage it effectively.
文摘Background and Objective Diastolic dysfunction of the left ventricle is a mechanical abnormality diagnosed primarily by echocardiogram, and can be distinguished into three separate degrees based on the severity of reduction in passive compliance and active myocardial relaxation. Methods A literature search was performed for basic science studies, clinical studies and major practice guidelines on the subject of diastolic dysfunction and diastolic heart failure. Important findings were analyzed and correlated with regard to clinical relevance. Results Left ventricular diastolic dysfunction appears to compromise exercise tolerance and is believed to contribute to the pathophysiology in patients with diastolic heart failure. In the clinical setting, however, oftentimes no clear distinction is made between echocardiographically diagnosed diastolic dysfunction and diastolic heart failure, and adequate treatment recommendations are sparse and aimed to prevent worsening and progression of clinical symptoms. To date, there is a lack of high powered trials assessing the possible progression rate from echocardiographically diagnosed diastolic dysfunction to the clinical diagnosis of diastolic heart failure. Furthermore, there are no solid indices to assess the degree of severity of diastolic dysfunction or its progression. Pure right ventricular diastolic dysfunction appears to be even less understood and under-recognized, although it may play a role in the development of both right and left heart failure. Currently there are few but interesting data on the possible interaction between ventricles with diastolic dysfunction and the overall affect on the development of heart failure. Conclusions The timeline and progression of diastolic dysfunction to diastolic heart failure have not been well established and warrant further investigation.
文摘It is of great importance to investigate an effective and reliable medication against chronic renal failure (CRF)-related erectile dysfunction (ED),which aims to improve patients' life qualities.The concentrations of cyclic guanosine monophosphate (cGMP) in the corpus cavernosal smooth muscle of both CRF and control rabbits were measured.The effects of various concentrations of tadalafil,papaverine,and sodium nitroprusside on the relaxation responses of corpus cavernosal smooth muscle pre-contracted with phenylephrine in CRF rabbits were observed.There was significant difference in the concentration of cGMP between CRF and control rabbits (P<0.01).Tadalafil had the greatest impacts on CRF rabbits when given the same concentration of papaverine or sodium nitroprusside and particularly significant differences were identified under the concentration levels of 10-5 and 10-4 mol/L (P<0.01).The results suggest that the cGMP concentrations of the corpus cavernosum had been greatly reduced in CRF rabbits compared with control rabbits and that tadalafil may be an ideal medication for use in the treatment of CRF-related ED.

Methods： Clinical and pathological data of 467 HCC patients was retrospectively reviewed, who underwent liver resection from January 2002 to December 2008 in the Affiliated Hospital of Medical College, Qingdao University, and the post-resectional liver dysfunction and failure risk factors were analyzed by univariate and multivariate analysis. Results： The morbidity of post-resectional liver dysfunction and failure was 1.7% and 2.1%. The post-resectional liver dysfunction and failure after HCC hepatectomy into the statistical analysis： univariate analysis revealed preoperative platelet level （〈 100 × 10^9）, serum albumin level （〈 35 g/L）, serum gamma-Glutamyl transferase （〉 64 U/L）, Child-Pugh classification （B）, MELD score （≥ 9）, intraoperative bleeding （-〉 1000 mL）, blood transfusion were positive factors, multivariate analysis （Logistic） revealed that preoperative platelet level （0.983, 95% CI = 0.971-0.995） and intraoperative blood transfusion （3.145, 95% CI = 1.027-12.028） were independent risk factors for post-resectional liver dysfunction and failure. Conclusion： Prevented liver failure and liver dysfunction occurring after liver resection, it is the key to accurate preoperative assessment of liver function and the patient＇s reserved liver functional, precise hepatectomy and reasonable blockage of hepatic inflow.
文摘<strong>Background:</strong><span style="white-space:normal;font-family:;" "=""> Various thyroid abnormalities have been reported during heart failure (HF). The present study aimed to evaluate the burden, type, and associated factors of thyroid disorders in Cameroonian patients with heart failure. <b>Materials and Methods:</b> We conducted a cross-sectional study from January to May 2020, involving volunteer adults followed for heart failure at the Yaoundé Central Hospital. Those receiving treatment that could cause thyroid dysfunction were excluded. Thyroid hormone levels (TSH, free T3, and free T4) were measured by enzyme-linked immunosorbent assay. <b>Results: </b>A total of 63 patients (30 women;47.6%) were included.
