Abstract
Heat stress seriously threatens fish survival and health, demanding immediate attention. Teprenone is a gastric mucosal protective agent that can induce heat shock protein expression. This research investigated the effects of teprenone on largemouth bass (Micropterus salmoides) subjected to heat stress. Juvenile fish were assigned to different groups: group C (control group, 0 mg teprenone/kg diet), T0, T200, T400, and T800 (0, 200, 400, and 800 mg teprenone/kg diet, respectively), which were fed for 3 days, followed by a day without the diet. All groups except group C were subjected to acute heat stress (from 24 °C to 35 °C at 1 °C per hour and then maintained at 35 °C for 3 h). The results were as follows: The critical thermal maxima were significantly higher in the T200, T400, and T800 groups compared with the T0 group (P < 0.05). Heat stress caused severe damage to the tissue morphology of the liver, while teprenone significantly reduced this injury (P < 0.05). Serum cortisol concentration decreased gradually as teprenone concentration increased, and the lowest concentration was observed in the T800 group (P < 0.05). Compared with the T0 group, the serum activities of aspartate aminotransferase, alanine aminotransferase, and gamma-glutamyl transferase were significantly lower in the T200, T400, and T800 groups (P < 0.05). The liver activities of catalase, total superoxide dismutase, and peroxidase were significantly higher in the T200 group than in the T0 group (P < 0.05). Transcript levels of the heat shock proteins (hsp90, hsp70, hspa5, and hsf1) and caspase family (caspase3 and caspase9) in the liver of the T200 group were significantly higher than those of the T0 group (P < 0.05). Western blot results showed that HSP70 and HSPA5 in the liver were significantly upregulated in the T200 group compared with the T0 group (P < 0.05). In summary, dietary teprenone improved thermal tolerance, alleviated heat stress damage in the liver, enhanced antioxidant capacity, and upregulated heat shock proteins in juvenile largemouth bass. This study offers theoretical support for applying teprenone in aquaculture to reduce financial losses caused by abiotic factors.

Abstract
BACKGROUND Gastrointestinal injuries caused by nonsteroidal anti-inflammatory drugs (NSAIDs) is a serious side effect in patients with rheumatoid arthritis (RA). However, effective therapeutic strategies have yet to be established. In this study, we investigated the therapeutic effects of teprenone (TEP), a gastric mucosal protective drug, on NSAID-induced gastrointestinal injuries in rats with RA (AA rats). METHODS Gastrointestinal injury was induced by oral administration of indomethacin (IMC), a typical NSAID. TEP was orally administered after IMC-induced gastrointestinal bleeding, and the stomach, jejunum, and ileum were excised. RESULTS On day 14 of IMC administration, lesion areas in the stomach, jejunum, and ileum were significantly larger in AA rats than in normal rats. When TEP was orally administered to AA rats, the lesion areas in the stomach, jejunum, and ileum significantly decreased compared with those in control rats (IMC-induced AA rats). Therefore, we measured NOS2 mRNA and NO levels, which were significantly decreased in rats with IMC-induced AA after treatment with TEP. CONCLUSIONS These results suggest that the oral administration of TEP may be useful for the treatment of NSAID-induced gastrointestinal injuries in patients with RA.

Abstract
OBJECTIVE To investigate the protective effect of teprenone on gastric mucosal injury induced by dual antiplatelet therapy in rats. METHODS Healthy, specifically pathogen free SD, rats were selected and divided into 4 groups: Normal group (normal rats, without any treatment), Model group (rats received dual antiplatelet therapy: aspirin and clopidogrel), Teprenone group (rats received dual antiplatelet therapy and teprenone) and Pantoprazole group (rats received dual antiplatelet therapy and pantoprazole). The gastric mucosal blood flow, ulcer index, gastric gel mucus thickness, the levels of gastrin (Gas), prostaglandin (PG), prostaglandin E2 (PGE2), endothelin-1 (ET-1) tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6 and IL-10 in serum, the levels of malondialdehyde (MDA), glutathione (GSH), superoxide dismutase (SOD) and myeloperoxidase (MPO) in the gastric mucosa, as well as the expression of vascular endothelial growth factor (VEGF) in the rat's stomach were measured. RESULTS Compared with the Normal group, the other groups showed more severe gastric injury, elevated levels of inflammatory factors (TNF-α, IL-1β, IL-6 and IL-10), elevated levels of MDA and MPO, as well as reduced levels of GSH, SOD and VEGF (all P<0.05). Compared with the Model group, the gastric mucosal lesions in the Teprenone group and the Pantoprazole group were improved significantly (both P<0.05). Compared with the Pantoprazole group, the Teprenone group had reduced levels of ET-1 and elevated levels of PG and PGE2 (all P<0.05). CONCLUSION Teprenone protects against gastric mucosal injury induced by dual antiplatelet therapy through inhibiting gastric mucosal inflammation inhibiting oxidative stress and improving gastric mucosa indices.

Abstract
AIMS Liver cirrhosis leads to cirrhotic cardiomyopathy (CCM) and chronotropic incompetence (CI). Heat shock protein 70 (Hsp70) regulates cellular apoptosis and autophagy in stress. Teprenone modulates the Hsp70 and protects against cellular injury. Thus, we aimed to evaluate the effect of teprenone on CI in biliary cirrhotic rats. MAIN METHODS Liver cirrhosis was induced in male Wistar rats through bile duct ligation (BDL). The chronotropic responses and QT interval were studied through electrocardiography (ECG) in sham, cirrhotic, and cirrhotic/teprenone (100 mg/kg) pre-treated groups. Brain natriuretic peptide (BNP), tumor necrosis factor alpha (TNF-α), interleukin 6 (IL-6), and monocyte chemo-attractant protein-1 (MCP-1), and alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels were investigated in serum. The Hsp70, B-cell lymphoma 2 (Bcl-2), and B-cell lymphoma 2-associated X protein (Bax) expressions were quantified through real-time polymerase chain reaction (Real-time PCR). KEY FINDINGS The chronotropic responses were decreased significantly in cirrhotic and cirrhotic/teprenone groups. The QT interval and serum BNP, TNF-α, IL-6, ALT, AST, and MCP-1 levels were increased significantly in the cirrhotic and decreased significantly, except BNP, in the cirrhotic/teprenone group. The Hsp70 and Bax expressions increased significantly in cirrhotic and decreased significantly in the cirrhotic/teprenone group while the Bcl-2 decreased significantly in cirrhotic and increased significantly in the cirrhotic/teprenone group. SIGNIFICANCE Teprenone does not relieve the CI and BNP changes in CCM while other indices are treated. Given that CCM is a multifactorial disease and needs to target other genes and proteins concurrent with Hsp70 to relieve CCM.

Abstract
OBJECTIVE This study aimed to investigate specific protein expression of injured intestinal mucosa induced by diclofenac, and explore the protective effects of teprenone on it. METHODS Intestinal damage of Sprague Dawley male rats was gradually induced by the intragastric administration of diclofenac. After the last drug administration, the intestinal mucosa was taken off with an interval of 24 h, subsequently, its general histological injury and ultrastructure were observed and analysed by a transmission electron microscope. The expression levels of PAR1 and PAR2 protein were detected by immunohistochemistry and real-time polymerase chain reaction (PCR). RESULTS The Reuter and Chiu scores of small intestinal damage were 5.63 ± 1.30 and 4.25 ± 0.70 respectively in the model group, which could be protected by teprenone (100 mg/kg⋅day) with the degree of 55.7% and 44%. Optical microscopy and transmission electron microscope showed that intestinal mucosa and ultrastructure were severely damaged. Distributed in the cytoplasm or aligned with the nucleus, the expression of PAR1 and PAR2 was significantly upregulated after the administration of diclofenac, while it was relieved after the treatment of teprenone. CONCLUSION Our study presents a new view that teprenone might protect NSAIDs-induced (diclofenac) intestinal injury via suppressing the expression of PAR1 and PAR2.

Abstract
Hypoxia stress may affect the fish intestine and thereby threaten the growth and survival of the fish. Teprenone is a clinically effective agent in protecting gastrointestinal mucosa. This study aims to assess the effect of teprenone in the intestine of Chinese sea bass Lateolabrax maculatus under intermittent hypoxic stress. L. maculatus juveniles were either raised under intermittent hypoxic condition or normal condition (NC). Part of the hypoxic-intervened fish were treated with teprenone at different concentrations (HTs), and the rest were regarded as hypoxic control (HC). Histological analysis was performed on the epithelial tissue of the fish intestine. High-throughput sequencing technology was used to analyze the diversity and composition of the microbial community in L. maculatus intestine. Reduced villi length and goblet cell, exfoliated enterocyte, and improper arrangement of villi were observed in HC compared with NC and HTs. Proteobacteria, Firmicutes, and Bacteroidetes represented the most abundant phyla in each sample. Significantly higher microbial diversity was detected in HC compared with NC (P < 0.05). At the phylum level, HC presented significantly decreased relative abundance of Proteobacteria, and significantly increased relative abundance of Bacteroidetes, Chloroflex, and Cyanobacteria compared with NC (P < 0.05). At the class level, HC showed significantly reduced relative abundance of Alphaproteobacteria and Bacilli, and significantly increased relative abundance of Clostridia, Gammaproteobacteria, and Bacteroides (P < 0.05). Teprenone protects the intestine from epithelial damages and maintains the microbial harmony in L. maculatus under intermittent hypoxic stress.

Abstract
Teprenone (geranylgeranylacetone) is one kind of safe and effective agent in gastrointestinal mucosa, which have been widely used in human and veterinary, but rarely used in aquaculture animals. In this study, Lateolabrax maculatus, an important economic fish species in southern China, was taken as the object of study to investigate the protective effect of teprenone on intestinal stress. The present study was designed to investigate the potential mechanism underlying the protection offered by teprenone to protect the gastrointestinal tract against hypoxia and reoxygenation injury of L. maculatus. (a) For oxidative stress parameters, SOD, CAT, and T-AOC in control group were higher than those in teprenone group. MDA content was significantly higher than that in teprenone group at N and 12h time points in intestine (P < 0.05), and at 12, 24, and 48 h time points in stomach. (b) For immune-associated proteins, LZM activity in the control group was lower than that in the teprenone group, and the difference between the two groups in stomach and intestine was significant at 12.48 h and 6.48 h time points, respectively (P < 0.05). Compared with time point N, the content of HSP70 in the control group increased at 0 h in intestine. At 0-48 h, intestine HSP70 content in the control group showed a gradually decreasing trend, which was higher than that in the teprenone group. (c) For apoptosis-related factors, the activity of Cyt-C, caspase9, and caspase3 increased first and then decreased in both groups. The content of Cyt-C in the control group was significantly higher than that in the teprenone group at N-3.6 h, and 3.48 h time points in stomach and intestine, respectively (P<0.05). The activity of caspase9 and caspase3 was higher than that in the teprenone group at N-48 h. Results indicated that acute hypoxia and reoxygenation cause the expression levels of oxidative stress and apoptosis-related factors in the stomach and intestine increased first and then decreased within 0-48 h. Acute hypoxia and reoxygenation also that causes the level of nonspecific immunity decreased first and then increased. A total of 400-mg/kg treatment of teprenone can protect stomach and intestinal tissues to a certain extent. It can effectively protect oxidative stress and apoptosis within 0-48 h after acute hypoxia and reoxygenation and enhance non-specific immunity.

Abstract
Objectives: Low-dose aspirin is the standard treatment for the prevention of cardiovascular events in at-risk patients. We performed a randomized, placebo-controlled study to determine the efficacy of teprenone for primary prevention of gastrointestinal injury in patients taking LDA for vascular protection.Methods: Patients were eligible for enrollment if they required aspirin 100 mg/day. Aspirin- naïve patients without gastroduodenal ulcer and Helicobacter pylori infection were randomized to receive teprenone 150 mg/day or placebo for 12 weeks. Primary outcome was assessed by the incidence rate of gastroduodenal ulcer. Secondary outcomes were assessed by the incidence rate of gastric mucosal injury, the improvement in modified Lanza score (MLS), gastrointestinal symptom rating scale (GSRS) and the change of gastric immunohistochemical expression for COX-1.Results: Total of 130 patients were randomized, 64 in teprenone group and 66 in placebo group. There was no incidence of ulcer after 12 weeks in both groups. Incidence of gastric mucosal injury was higher in placebo group than in teprenone group (40.0 vs. 13.38%, p = .039). Mean change of MLS was higher in placebo group than in teprenone group (0.767 ± 0.467 vs. 0.271 ± 0.158, p = .003). Scores of mucosal edema, hyperemia and hemorrhage and the change of GSRS were not different between the two groups. Change of COX-1 immunoreactive score was higher in placebo group than in teprenone group (2.433 ± 1.476 vs. 1.233 ± 0.955, p = .001). There were no treatment-related adverse events.Conclusions: Teprenone is effective in preventing gastric mucosal injury in patients taking LDA. Preventive effects of teprenone on LDA-related gastroduodenal ulcers require further investigation.

Abstract
The purpose of this study was to investigate the injury of aspirin and clopidogrel on small intestinal mucosa in rats and the protective effect of teprenone. The study found that aspirin and clopidogrel could cause intestinal mucosal injury in rats, which was even worse with dual drugs. The mechanism of mucosal injury included free radical injury induced by aspirin and decreased synthesis of vascular endothelial growth factor (VEGF) by clopidogrel. Teprenone may repair intestinal mucosa via boosting VEGF level.

Abstract
AIM To assess the influence of Shenqi Jianwei granules combined with teprenone on gut hormones and inflammatory factors in patients with chronic atrophic gastritis of spleen-stomach deficiency-cold type.
METHODS A total of 150 patients with chronic atrophic gastritis of spleen-stomach deficiency-cold type who were treated at Wenzhou Integrated Hospital of Traditional Chinese and Western Medicine from September 2016 to September 2017 were randomly divided into an experimental group and a control group, with 75 cases in each group. Both groups were treated with amoxicillin for anti-infection as well as omeprazole and colloidal pectin to protect the gastric mucosa by acid suppression. Both groups were treated with oral teprenone on the basis of routine treatments, and the experimental group was additionally treated with Shenqi Jianwei granules. After four months of treatment, the clinical efficacy, TCM syndromes scores, serum levels of gut hormones and inflammatory factors, and treatment efficacy for Helicobacter pylori (H. pylori) infection were compared between the two groups.
RESULTS The clinical efficacy was better in the experimental group than in the control group (P < 0.05). After treatment, the TCM syndrome scores of abdominal distension, stomach pain, anorexia, and fatigue in both groups were significantly decreased compared with the scores before treatment (P < 0.05), and these TCM syndrome scores in the experimental group were significantly lower than those in the control group (P < 0.05). Before treatment, there was no significant difference in the levels of endothelin (ET), epidermal growth factor (EGF), calcitonin gene-related peptide (CGRP), interleukin-6 (IL-6), interleukin-8 (IL-8), or tumor necrosis factor-alpha (TNF-α) between the two groups (P > 0.05). After treatment, the levels of ET, EGF, IL-8, IL-6, and TNF-α were decreased and the CGRP was increased in both groups compared with those before treatment, and the improvement of each index in the experimental group was significantly better than that in the control group (P < 0.05). The treatment efficacy for H. pylori infection in the experimental group was significantly higher than that in the control group (P < 0.05).
CONCLUSION Shenqi Jianwei granules combined with teprenone have significant clinical efficacy in the treatment of chronic atrophic gastritis and can improve the patient's clinical symptoms and relieve the disease.

Abstract
AIM: To compare the therapeutic efficacy and safety of teprenone combined with short- versus long-term use of omeprazole in the prevention of re-bleeding after endoscopic hemostasis for NSAIDs-related ulcers.
METHODS: Patients with NSAIDs-related ulcers who underwent Monteggia liquid spraying for bleeding were randomly divided into four groups: a teprenone group (n = 28), an omeprazole group (n = 33), a short-term combination group (n = 31), and a long-term combination group (n = 35). The incidences of re-bleeding and adverse reactions occurring during the periods of 0-13, 14-26, 0-26 and 27-52 wk were compared among the four groups.
RESULTS: The rate of re-bleeding occurring between 0 and 13 wk was significantly higher in the teprenone group than in the other groups (all P < 0.05), and the differences were not statistically significant between the other three groups (all P > 0.05). During the periods between 14 and 26 weeks and between 27 and 52 wk, there were no statistically significant differences in the rates of re-bleeding between the four groups (all P > 0.05). The incidences of adverse reactions showed no significant differences between the four groups during the period of the first 26 weeks (all P > 0.05) or between the omeprazole group and long-term combination group during the period between 27 and 52 wk (P > 0.05), but were significantly higher in the omeprazole group and long-term combination group than in the short-term combination group (both P < 0.05).
CONCLUSION: Teprenone in combination with short-term use of omeprazole has comparable efficacy to long-term use of omeprazole but is associated with significantly less adverse reactions in preventing the occurrence of re-bleeding after NSAIDs-related ulcers.

Abstract
AIM: To explore the clinical efficacy of teprenone in the treatment of chronic atrophic gastritis (CAG).
METHODS: A total of 100 patients with CAG were chosen by endoscopic examination. A random, prospective and self control method was used. H pylori-positive patients received routine sterilization first, and then all the patients took teprenone for 24 wk. The clinical symptoms before and 4, 12 and 24 wk after therapy were evaluated, and endoscopic examination was performed before and 12 and 24 wk after therapy for pathological observation.
RESULTS: Clinical symptoms were significantly different before and after treatment (P < 0.05). The endoscopic results, pathological findings before and after therapy also had significant differences (P < 0.05). There were no marked differences in the above three aspects between H pylori-positive and -negative patients. After therapy, particles became thinner and metaplastic nodes diminished, together with obvious improvement of tissue pathology under endoscope.
CONCLUSION: Teprenone can relieve the clinical symptoms, endoscopic and pathological findings of CAG patients. Meanwhile, teprenone is convenient to use, with few side effects.
