ABSTRACT

Objective:To explore the clinical value of semi-ex vivo intestinal autotrans-plantation (IATx) for patients with mesenteric root regional tumors accompanied by vascular invasion.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 6 patients who underwent semi-ex vivo IATx in the Sichuan Academy of Medical Sciences & Sichuan Provincial People's Hospital from September 2021 to December 2022 were collected. There were 4 males and 2 females, aged (47±21)years. Observation indicators: (1) surgical conditions; (2) postoperative conditions; (3) follow-up. Measurement data with normal distribution were represented by Mean± SD. Count data were represented by absolute numbers. Results:(1) Surgical conditions. All 6 patients completed semi-ex vivo IATx successfully. The operation time, warm ischemia time, cold ischemia time, volume of intraoperative blood transfusion were (10.2±2.1)hours, (2.3±1.6)minutes, (49.2±15.6)minutes, (707±263)mL. Of the 6 patients, 3 patients were intraoperatively perfused with cold UW solution, while the other 3 were not. (2) Postoperative conditions. Results of postoperative pathological examination of the 6 patients showed 4 cases of pancreatic ductal adenocarcinoma, 1 case of cholangiocarcinoma, and 1 case of mesenteric fibromatosis. All 6 cases had nega-tive surgical margins and the duration of postoperative hospital stay was (19±4)days. None of the patient had gastrointestinal bleeding or anastomotic leakage postoperatively, and the autotransplanted intestine functioned well. There was no perioperative death, and intravenous rehydration was not required after discharge. (3) Follow-up. All 6 patients were followed up for (12±5)months. Only 1 patient with mesenteric fibromatosis had recurrence in the 7th month postoperatively, while the remaining 5 patients showed no sign of recurrence or metastasis. There were 4 of 6 patients with chronic diarrhea. They were improved after oral loperamide, bifidobacterium and pancreatin capsules. All 6 patients survived.Conclusion:Semi-ex vivo IATx for the treatment of patients with mesenteric root regional tumors accompanied by vascular invasion is safe and feasible, which can achieve good short-term efficacy.

ABSTRACT

Angiostrongylus cantonensis is a food-borne zoonotic parasite, and human infection may cause eosinophilic meningitis. Non-coding RNAs (ncRNAs) may regulate physiological and pathological processes at multiple biological levels; however, there are few studies pertaining to the regulatory role of ncRNAs in A. cantonensis infection. Based on publications retrieved from PubMed, Wanfang Data and CNKI, the regulatory role of ncRNAs in A. cantonensis infections mainly includes immune responses, cell apoptosis and signaling transduction, and ncRNAs may serve as biomarkers for diagnosis of angiostrongyliasis. This review summarizes the main roles of ncRNAs in A. cantonensis infections and the underlying mechanisms, so as to provide insights into diagnosis and treatment of angiostrongyliasis.

ABSTRACT

Objective To evaluate the effect of docosahexaenoic acid (DHA) on hepatic ischemia-reperfusion (I/R) injury in rats.Methods Fifteen male Sprague-Dawley rats, aged 8-10 weeks, weighing 250-300 g, were randomly divided into 3 groups (n =5 each) using a random number table: sham operation group (group S), hepatic I/R group (group I/R) , and group DHA.Hepatic I/R was induced by clamping the hepatic pedicle supplying the left and middle lobes of the liver for 60 min, followed by 24 h reperfusion in anesthetized rats.DHA 4 mg/kg was injected intravenously at 30 min before ischemia and 10 min of reperfusion in group DHA.The equal volume of solvent was given instead in S and I/R groups.Blood samples were taken from the inferior vena cava at 24 h of reperfusion for determination of serum alanine aminotransferase (ALT), and aspartate aminotransferase (AST) activities, and resolvin D1 concentrations.The rats were then sacrificed, and the livers were removed for determination of myeloperoxidase (MPO) activity (by spectrophotometry), and interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) mRNA expression (by quantitative real-time reverse transcriptase polymerase chain reaction).The livers were cut into sections which were stained with haematoxylin and eosin, and examined under light microscope.Results Compared to group S, the serum ALT and AST activities, serum resolvin D1 concentrations, and MPO activity, and IL-6 and TNF-α mRNA expression in liver tissues were significantly increased in I/R and DHA groups (P<0.05).Compared to group Ⅰ/R, the serum resolvin 1D1 concentrations, and MPO activity and TNF-α mRNA expression in liver tissues were significantly decreased (P<0.05) , and no significant difference was found in the serum ALT and AST activities in group DHA (P>0.05).There was no significant difference in pathological changes of the liver between group DHA and group I/R.Conclusion DHA can attenuate inflammatory responses during hepatic I/R, but it is not sufficient to mitigate liver injury in rats.
