Extensively infarcted giant solitary hamartomatous polyp treated with endoscopic full-thickness resection:A case report

BACKGROUND Solitary hamartomatous polyps(SHPs)are rare lesions.Endoscopic full-thickness resection(EFTR)is a highly efficient and minimally invasive endoscopic procedure that benefits from complete lesion removal and high safety.CASE SUMMARY A 47-year-old man was admitted to our hospital after experiencing hypogastric pain and constipation for over fifteen days.Computed tomography and endoscopy revealed a giant pedunculated polyp(approximately 18 cm long)in the descending and sigmoid colon.This is the largest SHP reported to date.Having considered the condition of the patient and mass growth,the polyp was removed using EFTR.CONCLUSION On the basis of clinical and pathological evaluations,the mass was considered an SHP.

Variant of Wellen’s syndrome in type 1 diabetic patient: A case report

BACKGROUND Wellen’s syndrome is a form of acute coronary syndrome associated with proximal left anterior descending artery(LAD)stenosis and characteristic electro-cardiograph(ECG)patterns in pain free state.The abnormal ECG pattern is classified into type A(biphasic T waves)and type B(deeply inverted T waves),based on the T wave pattern seen in the pericodial chest leads.CASE SUMMARY We present the case of a 37-year-old male with history of type 1 diabetes mellitus(T1DM),gastroparesis,mild peripheral artery disease and right toe cellulitis on IV antibiotics who presented to the emergency department with nausea,vomiting and abdominal pain for 3 d and as a result couldn’t take his insulin.Noted to have fasting blood sugar 392 mg/dL.Admitted for diabetic gastroparesis.During the hospital course,the patient was asymptomatic and denied any chest pain.On admission,No ECG and troponin draws were performed.On day 2,the patient became hypoxic with oxygen saturation 80%on room air,intermittent mild right-sided chest pain which he attributed to vomiting from his gastroparesis.Initial ECG done was significant for Biphasic T wave changes in leads V2 and V3 and elevated high sensitivity troponin.Patient was transitioned to cardiac intensive care unit and cardiac catheterization performed with result significant for extensive coronary artery disease.CONCLUSION This case highlights an exceptional manifestation of Wellen's syndrome,wherein the right coronary artery and circumflex artery display a remarkable 100%constriction,alongside a proximal LAD stenosis of 90%-95%.Notably,this occurrence transpired in a patient grappling with extensive complications arising from T1DM.Moreover,it underscores the utmost significance of promptly recognizing the presence of Wellen's syndrome and swiftly initiating appropriate medical intervention.

Existence and Concentration of Sign-Changing Solutions of Quasilinear Choquard Equation

In this paper, we study the following quasilinear equation of choquard type: where A(x,t) is given real functions on RN × R and with N ≥ 3, 1 p N, max{N-2p,1} α N, , and ε > 0 is a small parameter, Iα is the Riesz potential. We establish for small ε the existence of a sequence of sign-changing solutions concentrating near a given local minimum point of the bounded potential function V by using the method of invariant sets of descending flow, perturbation method and truncation technique. .

Prophylactic captopril reduces perioperative myocardial ischemia in dogs

Perioperative myocardial ischemia(PMI) is mainly caused by increasesin sympathetic nervous system activity due to stress,which results incoronary endothelial dysfunction,hence that it is hypothesized thatcaptopril may improve PMI.In our study,twenty mongrel dogs wererandomized for four groups;group Ⅰ:control,group Ⅱ:myocardialinfarction (MI) model,Group Ⅲ:MI+partial gastrectomy,group Ⅳ:MI+captopril+partial gastrectomy.Myocardial infarction wasproduced by ligation of left anterior descending coronary artery exceptthe group Ⅰ.In the group Ⅲ and Ⅳ,the hemodynamics,plasmaendothelin (ET) and nitric oxide (NO) on baseline,pre-andpostoperation were investigated two weeks after MI All animals werekilled by overdose anesthetic and their cardiac samples of non-infarction area taken for examining nitric oxide synthase (NOS)mRNA expression levels in vascular endothelial cells.Results:ingroup Ⅲ,the operation decreased the maximal rate of left ventricularpressure rise (LV+dP/dtmax),cardiac index (CI) and plasma No level,and increased left ventricular end diastolic pressure (LVEDP),time-course of isovolumic pressure fall (T constant),total peripheralresistance (TPR) and the levels of ET.In group Ⅳ,40 minutes afteradminstration of captopril,the TPR was decresed,and the t constantwas incresed significantly.The operation attenuated the TPR and Tconstant,but didn’t affect the other values.In situ hybridization it wasshowed that the expression levels of NOS mRNA was the highest ingroup Ⅰ,lower in groups Ⅱ and Ⅳ,and the lowest in group Ⅲ.Conclusions:1.Partial gastrectomy performed after myocardialinfarction may induce left ventricular systolic and diastolic dysfunction,and may produce coronary endothelial dysfunction;2.captopril canimprove left ventricular dysfuction and endothelial dysfunctioninduced by noncardiac operation.

The Alienation and Loneliness in Orpheus Descending

Orpheus Descending is written by American famous playwright Tennessee Williams. According to the portrayal of a series marginalized people, this drama presents the solitude in human beings' heart and the estrangement in interpersonal relations. This paper tries to analyze the solitude theme in this drama from philosophic aspect and realistic aspect, combining alienation theory and existentialism theory to analyze the reason and the manifestation of solitude.

The hypothalamic-spinal dopaminergic system:a target for pain modulation

Nociceptive signals conveyed to the dorsal horn of the spinal cord by primary nociceptors are subject to extensive modulation by local neurons and by supraspinal descending pathways to the spinal cord before being relayed to higher brain centers. Descending modulatory pathways to the spinal cord comprise,among others, noradrenergic, serotonergic, γ-aminobutyric acid(GABA)ergic, and dopaminergic fibers.The contributions of noradrenaline, serotonin, and GABA to pain modulation have been extensively investigated. In contrast, the contributions of dopamine to pain modulation remain poorly understood.The focus of this review is to summarize the current knowledge of the contributions of dopamine to pain modulation. Hypothalamic A11 dopaminergic neurons project to all levels of the spinal cord and provide the main source of spinal dopamine. Dopamine receptors are expressed in primary nociceptors as well as in spinal neurons located in different laminae in the dorsal horn of the spinal cord, suggesting that dopamine can modulate pain signals by acting at both presynaptic and postsynaptic targets. Here, I will review the literature on the effects of dopamine and dopamine receptor agonists/antagonists on the excitability of primary nociceptors, the effects of dopamine on the synaptic transmission between primary nociceptors and dorsal horn neurons, and the effects of dopamine on pain in rodents. Published data support both anti-nociceptive effects of dopamine mediated by D2-like receptors and pro-nociceptive effects mediated by D1-like receptors.

Negative pressure catheter drainage and jejunal feeding for descending necrotizing mediastinitis by interventional techniques:a retrospective study

Purpose: Descending necrotizing mediastinitis(DNM) is a lethal and acute suppurative disease. This report aimed to summarize our experience in the treatment of DNM with continuous negative pressure catheter drainage and transnasal jejunal feeding by interventional techniques. Materials and Methods: We retrospectively analyzed relevant clinical data of patients with DNM who underwent continuous negative pressure catheter drainage and transnasal jejunal feeding. All drainage catheters and jejunal feeding tubes were inserte d by interventional techniques. Results: In total, 21 patients were diagnosed with DNM by esophagography and computed tomography(CT). Catheters for the drainage of mediastinal abscesses as well as transnasal jejunal feeding tubes were successfully placed in all patients, indicating a 100% success rate. Of all patients, 13 underwent insertion of abscess drainage catheters through percutaneous puncture under DynaCT guidance, while eight had drainage catheter insertion through fistula orifices in the posterior nasopharyngeal wall or esophagus under fluoroscopic guidance. In total, 26 drainage tubes were inserted. One patient with diabetes died of sepsis and diabetic ketoacidosis 5 days postoperatively, while the remaining 20 patients showed good recovery with successful removal of the drainage catheters. Durations of catheterization were 45.2±50.44 days. The overall clinical success rate was 95.2%. Conclusion: The above described methods are non-surgical, minimally invasive and efficacious, and may be alternative therapeutic tools for patients who are not eligible for surgical operation, have a high postoperative risk, or are more likely to choose minimally invasive techniques.

Metabolite profile comparisons between ascending and descending colon tissue in healthy adults

BACKGROUND Obesity is a risk factor for colorectal cancer,yet metabolic distinctions between healthy right and left colon tissue,before cancer is diagnosed,remains largely unknown.This study compared right-ascending and left-descending colon tissue metabolomes to identify differences from the stool metabolome in normal weight,overweight,and obese adults.AIM To examine right and left colon tissue metabolites according to body mass index that may serve as mechanistic targets for interventions and biomarkers for colon cancer risk.METHODS Global,non-targeted metabolomics was applied to assess right-ascending and left-descending colon tissue collected from healthy adults undergoing screening colonoscopies to test the hypothesis that BMI differentially impacts colon tissue metabolite profiles.The colon tissue and stool metabolome of healthy adults(n=24)was analyzed for metabolite signatures and metabolic pathway networks implicated in progression of colorectal cancer.RESULTS Ascending and descending colon contained 504 host,food,and microbiotaderived metabolites from normal weight,overweight and obese adults grouped according to body mass index.Amino acids,lipids,and nucleotides were among the chemical types that further differentiated from the stool metabolite profiles.Normal weight adults had 46 significantly different metabolites between ascending and descending colon tissue locations,whereas there were 37 metabolite differences in overweight and 28 metabolite differences for obese adults(P<0.05).Obese adults had trimethylamine N-oxide,endocannabinoids and monoacylglycerols with different relative abundances identified between ascending and descending colon.Primary and secondary bile acids,vitamins,and fatty acids also showed marked relative abundance differences in colon tissue from overweight/obese adults.CONCLUSION There were metabolite profile differences between right-ascending and leftdescending colon tissue in healthy adults.Colon lipids and other metabolites in obese and overweight adults were distinguished from normal weight participants and associated with gut inflammation,nutrient absorption,and products of microbiota metabolism.

Spontaneous coronary artery dissection as a cause of myocardial infarction

Spontaneous coronary artery dissection(SCAD) is a rare disease that is usually seen in young women in left descending coronary artery and result in events like sudden cardiac death and acute myocardial infarction. A 70-year-old man was admitted to the emergency department with chest pain which started 1 h ago during a relative's funeral. The initial electrocardiography demonstrated 2 mm ST-segment depression in leads V1-V3 and the patient underwent emergent coronary angiography. SCAD simultaneously in two different coronary arteries [left anterior descending(LAD) artery and left circumflex(LCx)] artery was detected and SCAD in LCx artery was causing total occlusion which resulted in acute myocardial infarction. Successful stenting was performed thereafter for both lesions. In addition to the existence of SCAD simultaneously in two different coronary arteries, the presence of muscular bridge and SCAD together at the same site of the LAD artery was another interesting point which made us report this case.

Relation of coronary vulnerable plaque instability to serum levels of C-reactive protein and B-type natriuretic peptide in ACS.

Objective To explore the relationship between coronary vulnerable plaque instability and serum C-reactive protein(CRP) , B-type natriuretic peptide(BNP) levels in 85 patients with coronary heart disease. Methods Eighty-five patients( aged 63±16,M= 52 ) were divided into two groups.The control group was 28 patients with stable angina pectoris (SAP). The study group was 57 patients with acute coronary syndrome (ACS) .which were further divided into 21 patients with non ST elevated myocardial infarction (NSTEMI) and 36 patients with unstable angina pectoris (UAP). Plasma BNP and CRP were measured as well as coronary angiography made for all 85 patients. Plaques of coronary culprit arteries were classified as I -III three types according to Ambrose classification. Results (1). BNP and CRP levels of NSTEMI and UAP groups were significant higher than in SAP group. (2).The levels of BNP and CRP correlated with Ambrose classification, especially positively with Ambrose II type ,but no relation with coronary narosis. (3). The levels of BNP was much higher in patients of left anterior descending or multiple coronary artery diseases .(4). The Plaques of coronary culprit arteries in high risk of NSTEMI and UAP patients were mostly Ambrose II or III type. Conclusions The prevalence of higher levels of plasma BNP and CRP in patients with ACS ,when compared with those of SAP, was associated with the instability of coronary vulnerable plaques (ie, Ambrose II type). The level of BNP was much higher in patients of left anterior descending or multiple complicated coronary diseases. So, BNP and CRP are not only markers of vulnerable plaques, but also indicators of ACS prognosis.

Doppler measurements in fetal descending aorta and umbilical artery can predict borderline oxygenation in pre-eclampsia and HELLP syndrome

Objective: To determine diagnostic utility of Doppler measurements in fetal descending aorta and umbilical arteries in predicting intrauterine growth retarded (IUGR) fetuses at risk in pregnancies complicated by preeclampsia and/or HELLP syndrome. Methods: Doppler measurements were taken in fetal descending aorta and umbilical arteries of 53 patients with pre-eclampsia, 10 of whom had HELLP syndrome using fetometry (ACUSON 128XP/10, 3.5 MHz probe). These values were compared with those of 44 appropriate-for-gestational age singleton pregnancies (AGA). Doppler Indices (Resistance Index (RI), Systolic/Diastolic (S/D) ratio) and end-diastolic flows were related to fetal heart rate (FHR) during contraction stress test, to cord blood parameters (pH, Base Excess) and to Apgar Scores. Results: In contrast to AGA fetuses, IUGR fetuses had decreased end-diastolic flow and an increase of Doppler Indices significantly earlier in the descending aorta (p < 0.05), compared to umbilical artery. Increased RI’s, S/D ratios and a decrease of end-diastolic flow in fetal aorta were significantly correlated to frequency of FHR decelerations during contraction stress tests, pH, Base Excess (p < 0.01) and Apgar Scores in IUGR fetuses. Conclusion: A decrease in end-diastolic flow paralleled with an increase in Doppler indices in fetal descending aorta reflect oxygen deprivation in IUGR fetuses during pre-eclamptic pregnancies with or without HELLP syndrome. While ductus venosus and umbilical artery are more frequently used nowadays to determine fetal oxygen deprivation, Doppler measurements in fetal descending aorta provide additional information for early detection of fetuses at risk for IUGR in pregnancies complicated with pre-eclampsia and/or HELLP

ISSR Analysis of Hybrid Descendants of Roses

Four different rose hybrid populations were analyzed by ISSR technique with nine polymorphic primers. All of the primers produced 64 bands, of which 59 were polymorphic. The average of polymorphic bands was 6.6 for each primer. The percentage of polymorphism ranged from 57.1% to 100%, with an average of 92.3%. An UPGMA dendrogram showed five groups. The primer numbered with PI9 and PI11 had relatively high resolution in identifying the F 1 offspring in this research.

The central nucleus of amygdala is involved in tolerance to the antinociceptive effect of NSAIDs

Aim: Repeated microinjections of non-opioid an-algesics into the midbrain periaqueductal gray matter and rostral ventro-medial medulla induce antinociception with development of tolerance. Antinociception following systemic administra-tion of non-steroidal anti-inflammatory drugs (N SAIDs) also exhibit tolerance. Presently our aim was to investigate the development of tolerance to the antinociceptive effects of NSAIDs analgine, ketorolac, and xefocam microinjected into cen-tral nucleus of amygdala (Ce) in rats. Methods: Under anesthesia with thiopental a stainless steel guide cannula was stereotaxically implanted uni- laterally or bilaterally into the Ce using stereo-taxic atlas coordinates, and anchored to the cra- nium by dental cement. Five days after surgery, 3 μl of these NSAIDs were injected via the injec-tion cannula while the rat was gently restrained. Twenty min post microinjection, i.e. 10-min be-fore the peak of the drugs’ effect is normally rea- ched, animals were tested with tail flick (TF) and hot plate (HP) tests. On the 5th experimental day all animals received a Ce microinjection of mor-phine. Results: Daily microinjection of NSAIDs into the Ce uni- or bilaterally, produced antino-ciception with development of complete toler-ance over a 5-day period. Following the treat-ment period, morphine microinjection into the Ce failed to elicit antinociception, indicating cro- ss-tolerance to the antinociceptive effect of N SAIDs. In other words, the “non-opioid tolerant” rats showed cross-tolerance to morphine. Con-clusions: Our data confirmed the suggestion that NSAIDs interact with endogenous opioid systems, which likely play a key role in the development of tolerance to the antinociceptive effects of NSA IDs.

Artin Transfer Patterns on Descendant Trees of Finite p-Groups

Based on a thorough theory of the Artin transfer homomorphism from a group G to the abelianization of a subgroup of finite index , and its connection with the permutation representation and the monomial representation of G, the Artin pattern , which consists of families , resp. , of transfer targets, resp. transfer kernels, is defined for the vertices of any descendant tree T of finite p-groups. It is endowed with partial order relations and , which are compatible with the parent-descendant relation of the edges of the tree T. The partial order enables termination criteria for the p-group generation algorithm which can be used for searching and identifying a finite p-group G, whose Artin pattern is known completely or at least partially, by constructing the descendant tree with the abelianization of G as its root. An appendix summarizes details concerning induced homomorphisms between quotient groups, which play a crucial role in establishing the natural partial order on Artin patterns and explaining the stabilization, resp. polarization, of their components in descendant trees T of finite p-groups.

Acute Type A Aortic Dissection—Replacement of Ascending Aorta, Aortic Arch and Antegrade Stenting of the Descending Thoracic Aorta Using the Thoraflex™Hybrid Plexus Device (Terumo Aortic)—“Frozen Elephant Trunk”: The Plymouth Way!

Objectives: To describe our technique for the implantation of the Thoraflex Hybrid prosthesis for replacement of the aortic arch in a safe and reproducible way. Materials: Thoraflex™ Hybrid Plexus Device (Terumo Aortic). Design: Drawing on our own experience over the past 4 years in the management of acute type A aortic dissection, we have distilled the essentials of our “Frozen Elephant Trunk” technique which have led us through our own learning curve to the improved management of this taxing condition. Method/ Results: Small extension of the median sternotomy incision along the medial border of sternocleidomastoid muscle. End to side graft anastomosis near the origin of the left subclavian artery during cooling on bypass towards 20 degrees. Attention to cardiac protection and maintenance of cerebral perfusion during the shortened corporeal arrest period. Excellent results in 24 consecutive AAAD patients with just one hospital mortality. Conclusions: We believe we are entering a new phase in the treatment of AAAD, facilitated by the availability of a hybrid prosthesis which combines expanding stent technology with familiar surgical graft material. Our particular management of the left subclavian artery and of the cerebral circulation during implantation has contributed to an expeditious and reproducible method of treating dissection within the arch of the aorta and beyond.
