Effect of volatile oil of amomum on expressions of platelet activating factor and mastocarcinoma-related peptide in the gastric membrane of chronic gastritis patients with helicobacter-pylori infection / 中国结合医学杂志

<p><b>OBJECTIVE</b>To observe the effect of volatile oil of amomum (VOA) on the expressions of mastocarcinoma-related peptide (PS2) and platelet activating factor (PAF) in helicobacter pyloriassociated gastritis (HPG) and to analyze its potential mechanism.</p><p><b>METHODS</b>Eighty patients with HPG were randomly assigned to two groups, 42 patients in the treated group treated with 0.5 mL VOA, thrice per day; and the 38 patients in the control group receiving Western tertiary medicinal treatment. Gastroscopic picture and helicobacter pylori (HP) infection (by quick urease and Warthin-Starry stain) of the gastro-membrane, expressions of PS2 and PAF (by immunohistochemical assay and Western blotting) as well as the contents of aminohexose and phospholipid (by Neuhaus method) in the gastric membrane of all patients were detected before treatment and 4 weeks after treatment. The clinical efficacy in the two groups was compared.</p><p><b>RESULTS</b>The total effective rate in the treated group was 88.1%, which was significantly higher than that in the control group (78.9%, P<0.05). After treatment, in the treated group, gastric membranous contents of aminohexose and phospholipid was increased, expression of PS2 elevated but that of PAF lowered, all showing significant difference as compared with those in the control group (P<0.01). In the control group, the expressions of PS2 and PAF changed insignificantly. The radical eliminating rate of HP in the treated group and the control group was insignificantly different between them (76.1% vs. 65.8%, P>0.05).</p><p><b>CONCLUSION</b>The mechanism of VOA for anti-gastritis might be related with its action in increasing the expression of PS2 and decreasing the expression of PAF, and thus regulating the hydrophobicity of the gastric membrane.</p>

Nuclear factor-kappaB mRNA and protein expression in stomach tissue of rats with gastric ulcer recurrence and effect of jianwei yuyang granule on its expression / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To observe the inflammatory reaction, nuclear factor-kappaB (NF-kappaB) mRNA and protein expression in stomach tissue of rats with gastric ulcer recurrence and the effect of Jianwei Yuyang granule (JYG) on them.</p><p><b>METHODS</b>Gastric ulcer and its recurrent lesion were successively induced by acetic acid and interliukin1-beta (IL-1beta), and the model rats were divided into the sham operation group, the model group, the omeprazole (correction of omepraxole) group and the JYG group to observe the state of chronic inflammatory cell, neutrophil count, NF-kappaBmRNA and protein expression in stomach tissue.</p><p><b>RESULTS</b>On the 16th and 92th day after administration, the increase of chronic inflammatory cell, neutrophil, NF-kappaBmRNA and protein expression in the model group was more significant than those in the sham operated group (P < 0.01), while that was lower in the JYG group than in the model group (P < 0.05, P <0.01), but with no remarkable difference to the omepraxole group. In addition, the mRNA and protein expression of NF-kappaB were correlated closely with the count of chronic inflammatory cell and neutrophil respectively (P < 0.01).</p><p><b>CONCLUSION</b>NF-kappaB may play an important role in regulating inflammatory reaction during the healing and recurrence processes of gastric ulcer induced by acetic acid. JYG may suppress inflammatory reaction by inhibiting the activation and expression of NF-kappaB in stomach tissue, which may be one of the mechanisms of JYG in preventing the recurrence of gastric ulcer.</p>

Exploration on correlation of syndrome proteomics and syndromatology of TCM / 中国中西医结合杂志

The advent of the Post-Human Genome Project Era, represented by the raising of proteomics, would inevitably lead to the change of molecular biology from topical view to holistic with its thought turning from linear to complex mode. Based on the proteomics development in recent years, the authors summarized the methodology of TCM syndromatologic research, advocated in using two-dimensional gel electrophoresis (2-DE) and bioinformatics to identify different proteins. Proteomics should be led into the research of TCM syndrome categorization and the rule of evolution, which is necessary for researching the integration of the TCM study with proteomics and even with modern molecular biology based on molecular epidemiology level. Owing to the gradually developed coherence and mutual penetration of proteomics and TCM on the thinking method in studying life science, it has denoted the necessity and importance of integration of TCM and Western medicine in investigating the complex vital life phenomena.

Effects of jianwei yuyang granule on inflammatory reaction and NF-kappaB expression in rat gastric mucosa of ulcer healing and recurrence / 中国中药杂志

<p><b>OBJECTIVE</b>To observe the effects of Jianwei Yuyang granule (JWYY) on inflammatory reaction and NF-kappaB expression in rat gastric mucosa of ulcer healing and recurrence.</p><p><b>METHOD</b>Gastric ulcer was induced in rat by acetic acid according Okeba's method with some modification and the recurrence model was induced by IL-1beta. Pathohistology of ulcer healing and recurrence was observed. Density of inflammatory cell infiltrating regenerative mucosa, NF-kappaB protein and mRNA expression were measured.</p><p><b>RESULT</b>JWYY had effects on improving the quality of ulcer healing, reducing the rate of ulcer recurrence, decreasing the density of inflammatory cell infiltrating regenerative mucosa and suppressing the activation and expression quantity of NF-kappaB protein and mRNA.</p><p><b>CONCLUSION</b>JWYY may promote the ulcer healing and prevent the recurrence of the gastric ulcer by suppressing the activation of NF-kappaB and the following inflammatory reaction.</p>

Therapeutic effects of the combination of traditional Chinese medicine and western medicine on patients with peptic ulcers / 中南大学学报(医学版)

OBJECTIVE@#To explore the therapeutic effects and mechanisms of the combination of traditional Chinese medicine and western medicine on patients with peptic ulcers.@*METHODS@#One hundred and twenty patients were randomly divided into 6 groups. Another 10 patients as the control group were confirmed with no peptic ulcers by endoscope, but had digestive tract symptoms. The clinical effects were compared among each group after the one month treatment.@*RESULTS@#The clinical effects of the combination of Jianweiyuyang granules and ranitidine capsules were better than those of western medicine, with improvement in symptoms and syndrome (P 0.05). The combination of Jianweiyuyang granules and ranitidine capsules could significantly upregulate the expression of MUCSAC mRNA (P < 0.01), while downregulate the expression of ETAR mRNA (P < 0.01).@*CONCLUSION@#There is obvious advantage in treating peptic ulcers by the combination of Jianweiyuyang granules and ranitidine capsules, and its mechanisms may be to protect the gastric mucosal barrier by up-regulating the expression of MUCSAC mRNA and to improve the gastric mucosal blood flow by down-regulating the expression of ETAR mRNA.
