摘要： Sijunzi decoction (SJZD) is a Chinese classical formula to treat spleen qi deficiency syndrome (SQDS) and has been widely used for thousands of years. However, the quality control (QC) standards of SJZD are insufficient. Chinmedomics has been designed to discover and verify bioactive compounds of a variety of formula rapidly. In this study, we used Chinmedomics to evaluate the SJZD’s efficacy against SQDS to discover the potential quality-markers (q-markers) for QC. A total of 56 compounds in SJZD were characterized , and 23 compounds were discovered . A total of 58 biomarkers were related to SQDS, and SJZD can adjust a large proportion of marker metabolites to normal level and then regulate the metabolic profile to the health status. A total of 10 constituents were absorbed as effective ingredients that were associated with overall efficacy. We preliminarily determined malonyl-ginsenoside Rb2 and ginsenoside Ro as the q-markers of ginseng; dehydrotumulosic acid and dihydroxy lanostene-triene-21-acid as the q-markers of poria; glycyrrhizic acid, isoglabrolide, and glycyrrhetnic acid as the q-markers of licorice; and 2-atractylenolide as the q-marker of macrocephala. According to the discovery of the SJZD q-markers, we can establish the quality standard that is related to efficacy.

Effects of Decoction on plasma proteome in cirrhosis: preliminary experimental study with rats

《医学前沿（英文）》 2008年 第2卷 第1期   页码 39-44 doi: 10.1007/s11684-008-0008-z

摘要： The aim of this paper is to study the effects of Decoction on the plasma proteome in cirrhotic rats. Twenty-six male Sprague-Dawley (SD) rats were randomly divided into three groups: cirrhotic model group ( = 10), treated with CCl (CCl/olive oil: v/v = 1:1); Decoction intervention group ( = 10), treated with CCl+ Decoction; and normal control group ( = 6), treated with olive oil only. After 8 weeks, blood samples were collected from the inferior vena cava to undergo bi-dimensional electrophoresis (2DE) and analysis by PDQuest 7.3 software. Differential protein spots were cut, enzyme hydrolysis was conducted, and peptide fragments extracted from the mixture underwent mass spectrometry (MS) with MALDI-TOF-TOF-MS. The liver fibrogenesis was assessed using a digital image analysis instrument of Masson’s trichrome stained sections. The fibrosis area of the Decoction was (8.9 ± 3.7)%, significantly smaller than that of the cirrhotic model group [(12.4 ± 4.7)%, < 0.05]. Ten markedly changed protein spots were identified by MALDI-TOF-TOF-MS. Eight of the 10 proteins, including plasma glutathione peroxidase, plasma glutathione peroxidase precursor, prealbumin, haptoglobin, apolipoprotein A-IV precursor, complement C4, inter-alpha-inhibitor H4 heavy chain, and serine/threonine-protein kinase microtubule-affinity regulating kinase 1 (MARK1) were expressed very lowly in the cirrhotic model group while they were expressed highly in the Decoction group. The expression of liver regeneration-related protein LRRG03 and vimentin increased in the cirrhotic model group, and reduced in the Decoction group. Some proteins related to oxidative stress, cell proliferation and transformation have changed in the plasma of cirrhosis induced by CCl. Decoction promotes protein synthesis and plays an anti-fibrotic role by anti-oxidation and accommodation of cell proliferation and transformation.

摘要： This paper aims to investigate the effects of (枳黄) decoction on CD14 expression in the lipopolysaccharide signal transduction pathway of alcohol-induced liver disease in rats. Seventy-five Wistar rats were randomly divided into three groups. Ethanol (56%, weight/volumn) was intragastrically administrated to 50 rats (14mL/kg body weight per day) for 10 days to establish a model of alcohol-induced liver disease, and 25 of these 50 rats were treated with decoction simultaneously. Liver injury was evaluated by biochemical examination. The plasma content of endotoxin was assayed by biochemistry. The expression of CD14 mRNA and protein in rat liver was measured by reverse transcriptional polymerase chain reaction and immunohistochemistry, respectively. decoction pretreatment significantly protected against acute alcohol-induced liver injury, which was evidenced by the decrease of elevated serum alanine aminotransferase and aspartate aminotransferase. In addition, the level of plasma endotoxin and up-regulation of CD14 was also suppressed by decoction in alcohol-intoxicated rats. decoction can significantly reduce CD14 expression in the lipopolysaccharide signal transduction pathway, which is one of the most important mechanisms of decoction to treat hepatic injury induced by alcohol in rats.

Lingguizhugan Decoction, a Chinese herbal formula, improves insulin resistance in overweight/obese subjects

《医学前沿（英文）》 2022年 第16卷 第5期   页码 745-759 doi: 10.1007/s11684-021-0880-3

摘要： Lingguizhugan Decoction (LGZG) has been investigated in basic studies, with satisfactory effects on insulin resistance in non-alcoholic fatty liver disease (NAFLD). This translational approach aimed to explore the effect and underlying mechanism of LGZG in clinical setting. A randomized, double-blinded, placebo-controlled trial was performed. A total of 243 eligible participants with NAFLD were equally allocated to receive LGZG (two groups: standard dose and low dose) or placebo for 12 weeks on the basis of lifestyle modifications. The primary efficacy variable was homeostasis model assessment of insulin resistance (HOMA-IR). Analyses were performed in two populations in accordance with body mass index (BMI; overweight/obese, BMI ≥ 24 kg/m2; lean, BMI < 24 kg/m 2). For overweight/obese participants, low-dose LGZG significantly decreased their HOMA-IR level compared with placebo (−0.19 (1.47) versus 0.08 (1.99),P = 0.038). For lean subjects, neither dose of LGZG showed a superior effect compared with placebo. Methylated DNA immunoprecipitation sequencing and real-time qPCR found that the DNA N6-methyladenine modification levels of protein phosphatase 1 regulatory subunit 3A (PPP1R3A) and autophagy related 3 (ATG3) significantly increased after LGZG intervention in overweight/obese population. Low-dose LGZG effectively improved insulin resistance in overweight/obese subjects with NAFLD. The underlying mechanism may be related to the regulation of DNA N6-methyladenine modification of PPP1R3A and ATG3. Lean subjects may not be a targeted population for LGZG.
