ABSTRACT
Linggui Zhugan Tang(LGZG), a representative of warming spleen to resolve fluid retention, is widely used in various diseases caused by spleen deficiency and fluid retention (SDFR). Ancient doctors mostly focused on the theme of SDFR to analysis the composition of LGZG. Modern research has now found that most of the components of LGZG contain anti-inflammatory, anti-tumor and immune-modulating effects. At present, the pharmacological research of LGZG mainly involves clearance of β-amyloid (Aβ) and anti-neuroinflammation, regulation of lipid metabolism and insulin resistance, protection of myocardial cells and regulation of liquid metabolism as follow. LGZG can promote the clearance of Aβ by regulating the expression of Aβ transporters, including low-density lipoprotein receptor-associated protein-1 and terminal glycosylation product receptors, as well as reduce the inflammation of nerve cells by inhibiting the secretion of pro-inflammatory factors such as interleukin(IL) -1β,IL-6 and tumor necrosis factor-α(TNF-α) by microglia. The prescription can also affect the lipid metabolism and insulin resistance by regulating the levels of adiponectin, insulin and leptin, thus producing therapeutic effects on metabolic syndrome and non-alcoholic fatty liver disease. The protective mechanism of LGZG on myocardial cells mainly contains inhibition of the over-activation of nuclear transcription factor-κB(NF-κB) signaling pathway,up-regulation of Smad7 expression and down-regulation of Smad3 expression, regulation of inhibitor of nuclear factor kappa-B kinase (IKK)/NF-κB inhibitor (IκB)/NF-κB signaling pathway, inhibition of inflammatory factor production, and down-regulation of Caspase-3 and Caspase-8 expression. In addition,LGZG can also regulate aquaporins to affect water metabolism. And it also has significant antioxidant effects. As is known to all,the functional mechanism of traditional Chinese medicine (TCM) compound is closely related to the network regulation of TCM disease syndromes. Considered from this angle, it is helpful to carry out the "disease-syndrome-formula" research by means of network pharmacology characterized by "disease-target-drug", thus organically exploring the relationship between LGZG and SDFR from the microscopic perspective,and helping to explain the scientific connotation of SDFR and the biological mechanism of warming spleen to resolve fluid retention.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the positive ratio and clinical significance of PreS1Ag and anti-PreS1 in patients with chronic hepatitis B.</p><p><b>METHODS</b>428 patients with chronic HBV infection were collected, these patients were divided into e antigen-positive CHB group, e antigen-negative CHB group, inactive HBsAg carrier group and HBsAg serum conversion group. The difference of positive ratio of PreS1Ag and anti-PreS1 among all groups or between every two groups were analyzed; The relationship of PreS1Ag and anti-PreS1 with HBV M and HBV DNA were also analyzed. SPSS13.0 software was used for statistical treatment. Fourfold table chi-square test or matched-pairs chi-square test was used for enumeration data, and independent sampler t test or rank-sum test was used for measurement data.</p><p><b>RESULTS</b>The differences of PreS1Ag among four groups were statistically significant (X2=141.7, P<0.05). The positive ratio of PreS1Ag in e antigen-positive CHB group was 95.7%, followed by 82.8% in e antigen-negative CHB group, 13.2% in inactive HBsAg carrier group and 2.2% in HBsAg serum conversion group. The difference of positive ratio of anti-PreS1 between HBsAg seroconversion group and HBsAg positive group was statistically significant (X2=6.919, P<0.05), which indicated that anti-PreS1 had good correlation with HBsAg seroconversion. The average absorbance ratio of PreS1Ag in high viral replication group (179.30) was higher than that in low viral replication group (133.87), statistical significance appeared (Z=-3.86, P<0.05). Though the difference of absorbance ratio of anti-PreS1 between two groups had no statistical significance (P>0.05), descent trend was apparent with virus replication level ascending. We analyzed the concordance of anti-HBs and anti-PreS1 by matched-pairs chi-square test, result showed no statistical significance of detection rate between them, X2=0.262, P>0.05. Serum PreS1Ag, HBeAg or HBcAg in liver tissue in reflecting hepatitis B replication had correlation with HBV DNA (X2=33.840, 24.159, 4.854 in order, P<0.05). Correlation coefficient between PreS1Ag and HBV DNA was higher (r=0.628) than that between HBeAg and HBV DNA (r=0.563).</p><p><b>CONCLUSION</b>PreS1Ag was more sensitive than HBeAg in diagnosing viral replication in patients with chronic hepatitis B. Anti-PreS1 as protective antibody may be involved in clearance of hepatitis B, positive result indicated recovery of chronic hepatitis B.</p>
