ABSTRACT

Cardiovascular disease (CVD) is a major contributor to patient deaths worldwide, and its pathogenesis is complex and mortality rates are increasing every year. Numerous researches have shown that the gut microbiota and its metabolites were closely associated with the development of CVD, and gut microbiota was expected to be a potential new target for the treatment of CVD. Traditional Chinese medicine (TCM), characterized by its multi-component, multi-target and integrity, can play a therapeutic role in CVD by regulating the gut microbiota, which has obvious advantages in stabilizing the disease, improving heart function and enhancing quality of life, and is an ideal intestinal microecological regulator. Therefore, this review will mainly discuss the intimate association of gut microbiota and its metabolites with CVD, and the therapeutic strategies of TCM targeting gut microbiota to improve CVD, including regulating the composition of gut microbiota, protecting the intestinal mucosal barrier, influencing the intestinal immune function and modulating the metabolites of gut microbiota, in order to provide a reference for the research of TCM targeting gut microbiota for CVD.

ABSTRACT

GC-MS metabolomics was used to investigate the effects of fudosteine on lung cancer A549 cells in an inflammatory microenvironment. Eleven metabolites (malic acid, isoleucine, lactose, galactinol, creatinine, gluconic acid, oleic acid, phosphate, S-carboxymethyl-L-cysteine, uridine and tagatose) were identified in the metabolomics results and could be used as biomarkers of fudosteine treatment. Pathway enrichment analysis showed that the metabolic pathways of amino acids including isoleucine, valine, leucine, glycine, serine and threonine were significantly altered, as were the metabolic pathways of carbohydrates such as galactose and pentose phosphate. Fudosteine significantly reduced the level of inflammatory factors in A549 cells and corrected the inflammatory microenvironment by interfering with the effects of amino acid metabolites and amino acid metabolism pathways. This study reveals that fudosteine may be able to inhibit the continuous inflammatory response and prevent the further progression of lung cancer by suppressing the inflammatory microenvironment.

ABSTRACT

OBJECTIVE@#Hemorrhoidal disease (HD) is the most common proctological disease, with an estimated prevalence rate of 4.4%, and a peak in individuals between 45 and 65 years of age. This study was done to evaluate whether Lian-Zhi-San (LZS), a clinically used anti-hemorrhoidal ointment could alleviate the inflammatory injury, with its associated changes of inflammatory cytokines and morphology of anorectal tissues, in an experimental model of HD in rats.@*METHODS@#HD was induced by croton oil preparation (COP) applied to the anorectal region. Rats were then treated with cotton swabs soaked in LZS ointment, water or white vaseline, twice a day for 7 d. At the end of the experiment, HD was evaluated by measuring hemorrhoidal and biochemical parameters along with histopathological observations.@*RESULTS@#In this study, COP induced a significant increase in the macroscopic severity score, anorectal coefficient and Evans blue extravasation, compared to normal rats. Additionally, it greatly enhanced the expression and secretion levels of some important inflammation-related cytokines along with marked histological damage, compared to normal rats. Rats treated with LZS ointment experienced significantly ameliorated Evans blue extravasation (P < 0.05), decreased macroscopic severity score (0.86 ± 0.14 vs. 1.65 ± 0.16) and the anorectal coefficient (P < 0.01); its use also attenuated tissue damage and inhibited the expression and secretion levels of inflammation-related cytokines (interleukin-1β, interleukin-6 and tumor necrosis factor-α).@*CONCLUSION@#This study validates a preliminary understanding of the use of LZS ointment to treat inflammatory factors and tissue damage in an experimental model of HD in rats.

ABSTRACT

<p><b>BACKGROUND</b>Many investigators advocate anterior release combined with halo-femoral traction and posterior fusion when treating stiff thoracic curves in patient with adolescent idiopathic scoliosis (AIS). But the anterior operations often induce severe complications. Some surgeons choose posterior-only surgery with halo-femoral traction, posterior wide release and correction. But to the best of our knowledge, there are only rare prospective studies on these posterior-only surgeries for AIS patients who have a rigid curve more than 80° and flexibility less than 35%.</p><p><b>METHODS</b>Sixty-four AIS patients were recruited from September 2006 to June 2009. All patients had rigid curves and underwent spinal correction. They were randomly divided into group A (combined anteroposterior surgery) and group B (posterior-only surgery). Images and scoliosis research society-22 questionnaire (SRS-22) scores were performed pre- and post-operation and during follow-up visits. The operation time, blood loss, hospital days, and hospital charges were compared between the two groups.</p><p><b>RESULTS</b>These patients were followed for an average of 37.5 months (range, 24 - 65 months). No serious complications were observed. There were no significant differences between the two groups in gender, age, preoperative radiographic data, or preoperative SRS-22 score. The average operation time, blood loss, hospital days and hospital charges in group B were less than those in group A. The SRS-22 score in group B was better than in group A at post-operation and at final follow-up.</p><p><b>CONCLUSIONS</b>In AIS with a rigid curve more than 80° and flexibility less than 35%, strong halo-femoral traction with wide posterior spinal release and three dimensional spinal correction can provide better SRS-22 scores, comparable curve correction, shorter operation time, less blood loss, shorter hospital stays and lower charges when compared to combined anterior and posterior surgery.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate relationship between expressions of hypoxia inducible factor-1alpha (HIF-1alpha) and insulin-like growth factor-II (IGF-II) as well as their correlation with angiogenesis and prognosis in gastric carcinoma.</p><p><b>METHODS</b>HIF-1alpha and IGF-II mRNA expression were analyzed using in situ hybridization, microvessel density (MVD) was determined by anti-CD34 immunostaining in 118 cases gastric carcinoma.</p><p><b>RESULTS</b>The positive rates of HIF-1alpha mRNA and IGF-II mRNA were 49.2% and 47.4%, respectively. In stage T3-T4 cases, positive rates of HIF-1alpha and IGF-II mRNA expression, the frequencies of vessel invasion, lymph node and distant metastasis were significantly higher than those in stage T1-T2 cases. The mean MVD in stage T3-T4 tumors, vessel invasion, lymph node metastasis and distant metastasis were significantly more frequent than those in stage T1-T2 tumors. The mean MVD in tumors with positive HIF-1alpha and IGF-II mRNA expression was significantly higher than those in tumors without HIF-1alpha and IGF-II mRNA expression. The expression of HIF-1alpha was positively correlated with IGF-II mRNA. There were positive correlations between MVD and expression of HIF-1alpha and IGF-II mRNA, respectively. The mean survival time and 5-year survival rate in cases with positive HIF-1alpha and VEGF expression and MVD value >/= 41.5 were significantly shorter than those in cases with negative HIF-1alpha and VEGF expression and MVD value < 41.5.</p><p><b>CONCLUSIONS</b>HIF-1alpha and IGF-II play an important role in tumor invasion and metastasis, especially in tumor angiogenesis. So test of the expression of HIF-1alpha and IGF-II may act as a useful index of treatment and prognosis.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate mRNA expression of syndecan-1 and heparanase in gastric carcinoma, and their correlation with the growth-pattern, invasion, metastasis and prognosis of gastric carcinoma.</p><p><b>METHODS</b>In situ hybridization technique was used to examine mRNA expression of syndecan-1 and heparanase in 118 specimens of gastric carcinoma.</p><p><b>RESULTS</b>The positive rates of syndecan-1 mRNA and heparanase mRNA were 42.4% and 55.9%, respectively. The expression of syndecan-1 mRNA and heparanase mRNA were related to tumor invasion depth (chi(2) = 32.95, P = 0.001; chi(2) = 23.19, P = 0.001), vessel invasion (chi(2) = 46.22, P = 0.001; chi(2) = 33.78, P = 0.001), lymph node (chi(2) = 28.62, P = 0.001; chi(2) = 25.43, P = 0.001) and distant metastasis (chi(2) = 63.30, P = 0.001; chi(2) = 65.76, P = 0.001), and syndecan-1 mRNA positive expression was related to tumor size (chi(2) = 6.25, P = 0.012). There was a negative relationship between Syndecan-1 mRNA and heparanase mRNA expression (r = -0.844, P = 0.001). The mean survival time of cases with low expression of syndecan-1 mRNA was significantly shorter than that of cases with high expression (r = 36.48, P = 0.001), and meanwhile, the mean survival time of heparanase mRNA positive cases was significantly shorter than that of cases with negative expression (r = 34.41, P = 0.001).</p><p><b>CONCLUSIONS</b>The mRNA expression of syndecan-1 and heparanase can predict the invasion and metastasis of gastric carcinoma, and can be used as markers of prognosis of gastric carcinoma.</p>
