Terazosin Stimulates Pgk1 to Remedy Gastrointestinal Disorders

Gastrointestinal disease is the most common health concern that occurs due to environmental, infectious, immunological, psychological, and genetic stress. Among them, the most frequent diseases are gastric ulcer (GU) and ulcerative colitis (UC). DSS-induced UC and ethanol-stimulated GU models resemble the pathophysiology of human gastrointestinal disease. The current study was designed to explore the anti-oxidation, anti-inflammation, anti-cell death properties of terazosin, an α-adrenergic receptor antagonist, in vivo and in vitro. Our results indicate that terazosin dramatically activates Pgk1, and upregulates glycose metabolism, evidenced by the enhanced ATP production and higher LDH enzymatic activity. Also, terazosin significantly enhances p-AKT expression and inhibits NF-κB p65 activation through abrogating the phosphorylation of IKBα, as well as lowers Caspase-1 and GSDMD expression. The findings in this study demonstrate that terazosin exhibits anti-inflammatory effects by downregulating NF-κB-GSDMD signal pathway, along with enhancing glycolysis for gastrointestinal disease treatment. Meanwhile, we also find terazosin ameliorates ethanol-induced gastric mucosal damage in mice. Collectively, as a clinical drug, terazosin should be translated into therapeutics for gastrointestinal disease soon.

Follow-up analysis and histopathological study of gastric mucosa in patients with Helicobacter pylori infection

Objective To investigate the histomorphological characteristics of the gastric mucosa and the prognosis in patients with Helicobacter pylori infection. Methods Progressive damage to the gastric mucosa was examined by immunohistochemistry in 2294 patients with H. pylori infection and follow-up information was analyzed. Results H. pylori initially colonized the mucus layer covered by the gastric mucosa epithelium, then selectively adhered to and destroyed the surface mucus cells causing intra-gastric and extra-gastric lesions. Gastric mucosal damage induced by H. pylori was divided into five stages according to the depth of H. pylori invasion and degree of lesion deterioration: mucilaginous, surface mucocellular, lamina propria lesion, mucosal atrophy, and intraepithelial neoplasia stages. Morphological follow-up analysis revealed no significant difference in 6-month curative effects between stage I and stage II, but significant differences were found between stages II and III, stages III and IV, and between stages IV and stage V, respectively. Conclusions This novel staging strategy may be a valuable tool for diagnosing and predicting the results of gastric mucosal damage induced by H. pylori infection.

Long-term survival after esophagectomy with distal pancreatectomy for locally advanced esophageal cancer with pancreatic invasion: a case report

Background The treatment for the locally advanced esophageal cancer invading adjacent organs is controversial. We performed a radical surgery for a patient suffering from lower esophageal cancer with pancreatic invasion, and led to long-term survival. Case presentation A 62-year-old man with dysphagia, was endoscopically diagnosed lower esophageal cancer. Abdominal computed tomography shows that the tumor formed a mass with the solitary metastatic abdominal lymph node, which invaded pancreas body and gastric body. He was diagnosed locally advanced esophageal cancer cStage IIIC. As chemoradiotherapy was difficult because of the high risk of gastric mucosal damage, radical esophagectomy with distal pancreatectomy and reconstruction of gastric conduit were performed. The postoperative course was uneventful and the patient was discharged 16 days after operation. At present, 7 years after surgery, he is still alive with disease-free condition. Conclusion Esophagectomy with distal pancreatectomy may be feasible for locally advanced esophageal cancer with pancreatic invasion in terms of curability and long-term survival.

EFFECT OF ASIATIC MANGROVE (RHIZOPHORA MICRONATA) LEAVES EXTRACT AS ANALGESIC IN MALE ALBINO DDW MICE (MUS MUSCULUS L.) INDUCED BY 0,7% ACETIC ACID

Background : Pain is an unpleasant emotional experience that illustrates ongoing tissue damage. Excessive use of non-steroidal anti-inflammatory drugs can cause peptic ulcer to gastric mucosal damage and perforation. Indonesia contains the largest area of mangrove forest in the world. There are 45 species of mangrove found and one of them is Asiatic Mangrove (Rhizophora mucronata). This type is easy to find and rich of alkaloids and flavonoids which can be used as analgesics. Method: This study used post-test only control group design. The number of mice that used was 25 mice, divided into 5 groups. Which were given different therapies aquadest 10mL/KgBW, acetosal 150 mg/KgBW, extract of Rhizophora mucronata 250 mg/KgBW, 500 mg/KgBW, and 1000 mg/kg bw. The pain was induced by 0,7% glacial acetic acid at a dose of 10 mL/KgBW. The writhes of the mice was being calculated with an interval of 10 minutes in 30 minutes. Result: The results of the analysis showed the decrease in writhes of mice in acetosal group dose 150 mg/kg bw, Rhizophora mucronata leaves extract dose 250 mg/kg bw, 500 mg/kg bw, and 1000 mg/kg bw. There was a significant difference in the results of the Mann-Whitney U test with p<0,05 in the aquadest group and the acetosal group with the Rhizophora mucronata leaves extract group dose 500 mg/kg bw, the difference between the acetosal group and the Rhizophora mucronata leaves extract group dose 250 mg/kg bw, and the difference between the Rhizophora mucronata leaves extract group dose 500 mg/kg bw and the Rhizophora mucronata leaves extract group dose 1000 mg/kg bw. Conclusion: Rhizophora mucronata leaves extract dose 500 mg/kg bw can provide analgesic effect and can reduce the writhing frequency in mice much better than acetosal group.

Should we routinely prescribe proton pump inhibitors peri-operatively in elderly patients with hip fractures? A review of the literature

Elderly hip fracture patients are at risk of stress-related gastric mucosal damage, and upper gastrointestinal bleeding is one of the underrecognized but devastating complications. Proton pump inhibitors (PPIs) offer effective prophylaxis against stress-related gastric mucosal damage. Systematic analysis of the literature revealed numerous articles on PPIs and hip fractures, but only three articles dedicated to the analysis of prophylactic use of PPIs in patients with a hip fracture. There is significant reduction in upper gastrointestinal bleeding following PPI prophylaxis and reduced 90-day mortality in elderly hip fracture patients on prophylaxis. PPIs are generally safe, cost-effective and based on available evidence. Their prophylactic use is justifiable in elderly patients with hip fractures. We suggest that PPIs be prescribed routinely peri-operatively in elderly hip fracture patients. Further level-one studies on the subject will allow for firmer recommendations.

Protective Effect of Prunus Dulcis Against Acetylsalicylic Acid Injury on Gastric Parietal Cells

Background: Acetylsalicylic acid is in common clinical use but has the side effect of causing gastric mucosal erosions and selective injury to parietal cells. Aim: To explore if prior treatment with Prunus dulcis (almond) had a protective effect against acetylsalicylic acid induced injury. Study design: Experimental study. Methodology: Albino mice weighing 30 to 40 grams were given two drops of almond oil without peel and 300 mg of finely ground whole almond kernel by oral gavage for sixty days followed by 400 mg/kg body weight of acetylsalicylic acid orally. Gastric mucosal damage was observed and recorded as ulcer index. The number of parietal cells/ sq. micrometer and area of parietal cells were observed and recorded under microscope in formalin fixed H and E stained sections. Data analyzed by SPSS 22.0v. Results: Mucosal damage, distortion of gastric glands and damage to parietal cells was pronounced in the positive control animals. The number of surviving parietal cells after acetylsalicylic acid insult in animals given almond oil was significantly higher when compared with positive control animals (p<0.001) and even better in animals receiving whole ground almond kernel. The area of parietal cells was also similarly larger in the treated animals. Conclusion: This study concluded Prunus dulcis offers protection against acute gastric mucosal injury and damage to the gastric parietal cells caused by acetylsalicylic acid in mice. Keywords: Prunus Dulcis, Parietal Cells, Gastric Erosions and Acetylsalicylic Acid.

Gastroprotective effects of Nelumbinis Rhizomatis Nodus-derived carbon dots on ethanol-induced gastric ulcers in rats

Aim: To evaluate the gastroprotective effects of Nelumbinis Rhizomatis Nodus carbon dots (NRN-CDs) on ethanol-induced gastric ulcers in rats. Materials & methods: NRN-CDs synthesized and characterized by transmission electron microscopy, ultraviolet, fluorescence and Fourier transform infrared spectroscopy, x-ray photoelectron spectroscopy, x-ray diffraction and zeta potential analyzer. Their gastroprotective effects toward ethanol-induced gastric ulcers were evaluated in male Sprague–Dawley rats. Results: NRN-CDs showed an average diameter of 2.33 ± 0.42 nm and a lattice spacing of 0.29 nm. Pretreatment with NRN-CDs significantly decreased the ulcer index and attenuated the severity of gastric mucosal damage, indicating that NRN-CDs exerted potent gastric protective effect. Moreover, the gastroprotection effect was related to the regulation of oxidative stress and inflammatory factors. Conclusion: NRN-CDs could be developed as a potential drug for the treatment of gastric ulcers.
