Abstract
Background Helicobacter Pylori (H. pylori) infection is the most important factor affecting clinical outcome in patients with gastric mucosal lesions. This study aimed to investigate H. pylori infection in patients with gastric mucosal lesions and their virulence genotype in Guiyang, China. Methods Pathological examinations of 1,364 biopsies from patients with upper gastrointestinal symptoms and H. pylori infection were analyzed according to different pathological types. The bacterial genome DNA was extracted from H. pylori strains isolated from gastric biopsies, and the cagA, vacA, and iceA virulence genes were detected and typed to analyze the correlation of their genotypes between different pathological lesions. Results The positive rate of H. pylori infection was approximately 19.9% (272/1,364), as determined by histopathological examination (HPE). It was more frequently detected in men than in women. A total of 85 H. pylori isolates were obtained from 280 clinical samples (positive rate 30.4%, 85/280). Of these 85 strains, cagA, vacA, and iceA genes were identified in 85.9%, 100%, and 83.5% of samples, respectively. Approximately 74.1% of strains were cagA East Asian type (cagA-ABD), and 11.8% of were cagA Western strains (cagA-AB, cagA-ABC), only present in patients with chronic non-atrophic gastritis. Gastric intraepithelial neoplasia and gastric cancer harbored both Asian strains. A total of 7 combinations of vacA genotypes were noted, among which s1c/m1b (30.6%) and s1c/m2 (41.2%) were the dominant genotypes. The predominant iceA genotype was iceA1 (64.7%). Conclusions We observed that the positive rate of H. pylori infection was related to the pathological type of patients' gastric mucosal lesions. Isolated H. pylori strains showed a unique genotype, mainly East Asian type cagA (ABD), vacA s1c/m2 genotype, and iceA1. These results provide an important reference for further studies of H. pylori in Guizhou province, China.

Abstract
The Tibetan high plateau is a low-oxygen environment, which may cause the pathogenesis of high-altitude polycythemia (HAPC). Gastric mucosal lesions (GML) are a common complication of HAPC. The molecular mechanisms involved in HAPC-induced GML have remained to be fully elucidated and were therefore investigated in the present study. Gastric tissues of patients with heavy, HAPC-induced GML and healthy controls were assessed by ultrastructural and histopathological analysis. In addition, terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick-end labeling and reverse transcription-quantitative polymerase chain reaction (RT-qPCR) analysis were used to detect cell apoptosis in the gastric mucosa tissues. Moreover, the expression of genes associated with the phosphoinositide-3 kinase (PI3K) pathway was assessed by RT-qPCR to investigate the mechanism of cell apoptosis in HAPC-induced GML. The results revealed a significant increase in the number of red blood cells, gastric vessels and the diameter of gastric mucosal vessels in HAPC-induced GML patients compared with those in healthy controls. In addition, more red blood cells were distributed in gastric tissue not only at the vascular level but also in the tissue space. The number of vacuoles was increased in the gastric mucosal cells. Furthermore, a significant increase in apoptosis of the gastric mucosal cells was identified. The expression of phosphatase and tensin homolog was significantly higher in gastric mucosa from patients with HAPC-induced GML compared with that in the healthy controls. All of the pathologic changes suggested that significant cell apoptosis occurred in the HAPC-induced GML tissues, which may be associated with the PI3K pathway. These findings may provide novel insight for the treatment of gastric lesions caused by HAPC in the future.

Abstract
Background and purpose Weaning is an important period of life and its timing may influence the resilence for later stress. One of the most important stress-related disorder is gastric ulceration. Methods Therefore we aimed to investigate the sensitivity of gastric mucosa to cold (at 16°C) water immersion stress (WIS for 3h) in adult (75-day-old) female and male rats after weaning them at different timepoints (at 17, 21, 30, 36 or 42 postnatal days). The connection with stress was studied by comparing control groups to those underwent WIS at the time of weaning and measuring corticosterone levels at the time of collecting the stomach samples. Results The timing of weaning has strong impact on all studied parameters. Stress-induced erosion development was the smallest in rats weaned at 36-day independently from preconditioning with WIS at weaning, or sex, despite a clear sex-effect on blood corticosterone levels and body weight. WIS at weaning influenced only the body weight in adult rats weaned at 30-day, being higher in stressed than in control groups. There was no clear overall correlation between erosion area and blood corticosterone measures. Conclusion Taken together our results confirm that the timing of weaning has long-lasting impact on the resiliance of gastric mucosa to ulcerogenic stressful events. In rats the postnatal day 30-36 seems to be optimal for weaning in both sexes as both earlier and later weaning increased vulnerability. Females seems to be more vulnerable to the effect of weaning than males.

Abstract
Capsaicin is a well-known component of red pepper. Recent studies have shown that capsaicin could prevent gastric ulcer provoked by various NSAID-s like acetylsalicylic acid (ASA). Primary objective of this human clinical phase I trial was to investigate whether two different doses of capsaicin co-administered with ASA could alter the inhibitory effect of ASA on platelet aggregation. 15 healthy male subjects were involved in the study and treated orally with 400 μg capsaicin, 800 μg capsaicin, 500 mg ASA, 400 μg capsaicin+500 mg ASA and 800 μg capsaicin+500 mg ASA. Blood was drawn before and 1, 2, 6 and 24 hours after the drug administration. After that epinephrine induced platelet aggregation was measured by optical aggregometry. Between treatments, volunteers had a 6-day wash-out period. Our results showed that capsaicin had no effect on platelet aggregation, while as expected, ASA monotherapy resulted in a significant and clinically effective platelet aggregation inhibition (p ≤ 0.001). The combined ASA-capsaicin therapies reached equivalent effectiveness in platelet aggregation inhibition as ASA monotherapy. Our investigation proved that capsaicin did not influence the inhibitory effect of ASA on platelet aggregation, thus the capsaicin-ASA treatment would combine the antiplatelet effect of ASA with the possible gastroprotection of capsaicin.

Abstract
Studies have shown that pre-moxibustion protects the gastric mucosa by up-regulating the expression of heat shock protein 70. However, the signaling pathway underlying this effect remains unclear. Rats were intragastrically administered absolute alcohol, causing obvious lesion of the gastric mucosa. Following pre-moxibustion at Zusanli (ST36) for 8 days, the ulcer index decreased to different degrees. The results of an enzyme linked immunosorbent assay and western blotting showed significant upregulation of heat shock protein 70 expression in the gastric mucosa and serum. None out of transection of the spinal cord, damage to the nucleus of the solitary tract, neurotomy of the vagal nerve and neurotomy of the common peroneal nerve affected the decrease in ulcer index or the increase in heat shock protein 70 expression in serum after pre-moxibustion at Zusanli, and heat shock protein 70 expression was obviously decreased in the gastric mucosa. These findings suggest that pre-moxibustion at Zusanli can protect the gastric mucosa against lesioning, and that the mechanism underlying this effect involves its induction of heat shock protein 70 expression. Neural pathways participate in the regulatory effects of moxibustion on heat shock protein 70 expression in the gastric mucosa.

Abstract
Previous studies have shown that somatic sensation by acupuncture and visceral nociceptive stimulation can converge in the nucleus tractus solitarii where neurons integrate signals impacting on the function of organs. To explore the role of the nucleus tractus solitarii in the protective mechanism of pre-moxibustion on gastric mucosa, nucleus tractus solitarii were damaged in rats and pre-moxibustion treatment at the Zusanli (ST36) point followed. The gastric mucosa was then damaged by the anhydrous ethanol lavage method. Morphological observations, enzyme linked immunosorbent assays, and western immunoblot analyses showed that gastric mucosa surface lesion and the infiltration of inflammatory cells were significantly ameliorated after pre-moxibustion treatment. Furthermore, the gastric mucosal damage index and somatostatin level were reduced, and epidermal growth factor content in the gastric mucosa and heat-shock protein-70 expression were increased. These results were reversed by damage to the nucleus tractus solitarii. These findings suggest that moxibustion pretreatment at the Zusanli point is protective against acute gastric mucosa injury, and nucleus tractus solitarii damage inhibits these responses. Therefore, the nucleus tractus solitarii may be an important area for regulating the signal transduction of the protective effect of pre-moxibustion on gastric mucosa.

Abstract
AIM To investigate any protective effect of early propranolol administration in the development of portal hypertensive gastropathy in cirrhotic rats. METHODS For the development of liver cirrhosis and portal hypertensive gastropathy, 60 rats underwent ligation of the left adrenal vein and complete devascularization of the left renal vein, followed by phenobarbital and carbon tetrachloride (CCl(4)) administration. After two weeks of CCl(4) administration, the rats were randomly separated into two groups. In group A, propranolol was continuously administered intragastrically throughout the study, whereas in group B normal saline (placebo) was administered instead. Hemodynamic studies and vascular morphometric analysis of gastric sections were performed after complete induction of cirrhosis. RESULTS Vascular morphometric studies showed higher numbers of vessels in all mucosal layers in the control group. Statistical analysis revealed a significantly higher total vascular surface in the control group compared to the propranolol group, but with no statistically significant difference between the mean vascular surfaces between the groups. Our study clearly shows that the increased mucosal blood flow is manifested by a marked increase of vessel count. CONCLUSION Early propranolol's administration in portal hypertensive cirrhotic rats seems to prevent intense gastric vascular congestion that characterizes portal hypertensive gastropathy.

Abstract
BACKGROUND We have reported the preventive effect of cimetidine, a histamine type 2 receptor antagonist, on decreased gastric mucosal blood flow induced by burn injury, a model of surgical stress. OBJECTIVE The present study was performed to assess the effects of cimetidine on gastric microcirculatory disturbance induced by surgical stress. METHODS Twelve male Wistar rats were anesthetized and a 30% full-thickness dorsal scald burn was inflicted. The total lengths of gastric erosions were measured using stereoscopic microscopy. Microvascular images in the basal region of the gastric mucosa were observed using an intravital microscope, and the diameters of venules and collecting venules were measured. Rolling leukocytes inside and along the venules, an indication of endothelial damage to the microcirculation, were observed. The rats were assigned to the cimetidine group or the control group (both, n = 6). Cimetidine 100 mg/kg was administered 30 minutes before and 2.5 hours after infliction of the burn injury. Animals in the control group were given only isotonic saline. Values are expressed as mean (SD). RESULTS Contraction of venules was easily observed in all rats in the control group. However, venular contraction was rarely observed in the cimetidine group. The total length of gastric erosions was significantly decreased in the cimetidine group compared with the control group (0.93 [0.58] μm vs 5.98 [5.18] μm, respectively; P < 0.05). The percentages of rolling leukocytes that passed the confluence of a prevenule and a venule were also significantly decreased in the cimetidine group compared with the control group (4.7% [7.3%] vs 22.6% [5.7%]; P < 0.01). The diameters of the venules and collecting venules were significantly larger in the cimetidine group (57.3 [6.8] μm and 75.9 [3.6] μm, respectively) than in the control group (30.9 [9.2] μm and 46.8 [8.0] μm, respectively) (both, P < 0.01). CONCLUSIONS The present study suggests that cimetidine may have a protective effect against gastric microcirculatory disturbances induced by burn injury, a model of surgical stress.
