ABSTRACT
OBJECTIVE To study the improvement effects of Shaoyao gancao decoction （SGD） on acute lung injury （ALI） in rats and its effects on the intestinal flora. METHODS Sixty SD rats were randomly divided into normal group （CON group， normal saline）， model group （MOD group， normal saline）， positive control group （DEX group， 5 mg/kg dexamethasone）， SGD low-dose， medium-dose and high-dose groups （SGD-L， SGD-M， SGD-H groups， 5.8， 11.6， 23.2 g/kg， calculated by crude drug）， with 10 rats in each group. Each group was given relevant medicine 10 mL/kg intragastrically， for 7 consecutive days. Thirty minutes after the last administration， CON group was given constant volume of normal saline via airway infusion， and other groups were given lipopolysaccharide （5 mg/kg） via airway infusion to induce ALI model. After 12 hours of modeling， the lung tissue wet/dry weight ratio was calculated， and the contents of interleukin 1β （IL-1β）， IL-6 and tumor necrosis factor α（TNF-α） in rat bronchial alveolar lavage fluid （BALF） were all detected； the pathological changes of lung tissue were observed after hematoxylin-eosin staining. The intestinal flora of rat feces was analyzed by 16S rRNA sequencing technology， and the correlation of differential bacteria genera with inflammatory factors was also analyzed. RESULTS Compared with MOD group， the infiltration of inflammatory cells in the lung tissue of rats in each SGD dose group was decreased， and the thickening of alveolar septum and pulmonary edema improved； lung tissue wet/dry weight ratio， the levels of IL-1β， IL-6 and TNF-α in BALF significantly decreased （P＜0.05 or P＜0.01）. SGD （low dose） could improve the intestinal flora disorder in ALI rats， restore the diversity and richness of intestinal flora， regulate the structure of flora， reduce the abundance of Lactobacillus， Streptococcus and Escherichia-Shigella， and increase the abundance of Firmicutes， Lachnospira， Ruminococcus， Clostridia，Dubosiella and Akkermansia. Through correlation analysis， it was found that the relative abundance of Lactobacillus， Streptococcus and Escherichia-Shigella was positively related to the levels of inflammatory factor IL-1β， IL-6 and TNF-α （P＜0.05 or P＜0.01）. The relative abundance of Lachnospira， Dubosiella， Firmicutes was significantly negatively correlated with the levels of inflammatory factors mentioned above （P＜0.05 or P＜0.01）. CONCLUSIONS SGD may improve ALI by reducing lung tissue injury and inflammatory response and regulating flora structure in rats.
ABSTRACT
This study aims to separate and characterize self-assembled nanoparticles(SAN) from Shaoyao Gancao Decoction(SGD) and determine the content of active compounds. Further, we aimed to observe the therapeutic effect of SGD-SAN on imiquimod-induced psoriasis in mice. The separation of SGD was performed by dialysis, and the separation process was optimized by single factor experiment. The SGD-SAN isolated under the optimal process was characterized, and the content of gallic acid, albiflorin, paeoniflorin, liquiritin, isoliquiritin apioside, isoliquiritin, and glycyrrhizic acid in each part of SGD was determined by HPLC. In the animal experiment, mice were assigned into a normal group, a model group, a methotrexate group(0.001 g·kg~(-1)), and SGD, SGD sediment, SGD dialysate, and SGD-SAN groups of different doses(1, 2, and 4 g·kg~(-1)) respectively. The psoriasis grade of mice was evaluated based on the pathological changes of skin lesions, the content of inflammatory cytokines, organ index and other indicators. The results showed that SAN obtained by centrifugation at 13 000 r·min~(-1) for 30 min was stable after dialysis for 4 times, which were uniform spherical nanoparticles with the particle size of(164.43±1.34) nm, the polydispersity index of(0.28±0.05), and the Zeta potential of(-12.35±0.80) mV. The active compound content accounted for more than 70% of SGD. Compared with the model group, SAN and SGD decreased the skin lesion score, spleen index, and inflammatory cytokine levels(P<0.05 or P<0.01) and alleviated the skin thickening and infiltration of inflammatory cells. However, the sediment group and the dialysate group had no obvious effect. SGD showed a good therapeutic effect on imiquimod-induced psoriasis in mice, and SAN demonstrated the effect equivalent to SGD in a dose-dependent manner. Therefore, we conclude that the SAN formed during decocting is the main active form of SGD, which can lower the levels of inflammatory cytokines, promote the normal differentiation of keratinocytes, and reduce the infiltration of inflammatory cells in the treatment of psoriasis lesions in mice.

In order to study the analgesic effect of Shaoyao Gancao Decoction, this paper discussed material basis and mechanism from the perspective of macromolecules in traditional Chinese medicine. Inspired by the phenomenon of turbidity after boiling Chinese medicine, this experiment took Shaoyao Gancao Decoction as the research object to study the formation process of precipitation during boiling. The results showed that aggregates with a certain shape were formed in the solvent during the boiling process, and the precipitate was obtained by standing and centrifuging. Analysis found that the precipitation was mainly composed of small molecules such as paeoniflorin, albiflorin, liquiritin, glycyrrhizic acid, isoliquiritin and gallic acid, and macromolecules such as protein and polysaccharide. The composition of precipitate was consistent with that of Shaoyao Gancao Decoction, but the analgesic effect of Shaoyao Gancao Decoction after removing the precipitate was significantly reduced. Based on these results, we isolated small molecular compounds, polysaccharides and protein from Shaoyao Gancao Decoction and their contents are 60.4, 700.7 and 207.2 mg·g-1 respectively. We get the ratio, polysaccharide: small molecule = 11.6∶1, protein: small molecule = 3.4∶1, the precipitate is prepared in the state of boiling. The characterization results showed that the particle size of the precipitate will change significantly after co-heating, and the content determination results showed that the content of the six small molecular compounds which was free in solvent was significantly reduced after the formation of the precipitate. The acetic acid writhing experiment proved that the precipitate has a good analgesic effect, and effectively reduced the levels of inflammatory factors prostaglandin E2 and nitric oxide, and increased the level of anti-inflammatory factor interleukin-10. These results proved that the precipitate in Shaoyao Gancao Decoction is an important material basis for analgesic effect, and macromolecules such as protein and polysaccharide are the main components of the precipitate. The study of macromolecules in the precipitate of Shaoyao Gancao Decoction not only provides new ideas and methods for elucidating the pharmacodynamic material basis of Shaoyao Gancao Decoction, but also provides a reference for analyzing the scientificity of traditional decoction.
ABSTRACT
OBJECTIVE To study the effects of self-assembled nanoparticles from Shaoy ao gancao decoction （SGD-SAN）on the in vitro release and intestinal absorption of the main components of Glycyrrhiza uralensis . METHODS Gancao single decoction （GSD），Shaoyao single decoction （SSD），mixed suspension of Shaoyao and Gancao single decoction （MSSGD）and SGD （i.e. Shaoyao-Gancao decoction ）were prepared ，and SAN was characterized. HPLC method was adopted to determine the contents of 7 main components （liquiritin apioside ， liquiritin， isoliquiritin apioside ， isoliquiritin， liquiritigenin， glycyrrhizic acid ， isoliquiritigenin）in G. uralensis . The dialysis bag method was used to investigate the effects of the formation of SGD-SAN on in vitro release of 7 main components in G. uralensis with pH 1.2 HCl solution and pH 6.8 phosphate buffered solution （PBS）as release media. Single-pass intestinal perfusion study was performed to investigate the effects of the formation of SGD-SAN on the intestinal absorption of 7 main components from G. uralensis . RESULTS SAN with particle size of 200-300 nm and polydispersity index of 0.3-0.5 was found in GSD ，MSSGD and SGD. GSD-SAN and MSSGD-SAN were in rod shape while SGD-SAN was irregularly spherical under transmission electron microscope. The results of in vitro release study showed that the formation of SGD-SAN could significantly increase in vitro release of liquiritigenin ，isoliquiritigenin and glycyrrhizic acid ，and had no effect on other components of G. uralensis in pH 1.2 HCl solution. The formation of SGD-SAN also had no effect on the release of each component from G. uralensis in pH 6.8 PBS. The results of intestinal perfusion experiments showed that the formation of SGD-SAN could significantly promote the absorption of each component from G. uralensis in the ileum. CONCLUSIONS- The formation of SGD-SAN significantly improves the in vitro release of poorly soluble components from G. uralensis and promotes the intestinal absorption of main components from G. uralensis ，which is the physical structure basis for the compatibility and synergy of Paeonia lactiflora and G. uralensis .

ABSTRACT
The quality markers (Q-markers) of traditional Chinese medicine (TCM) have become a topic of interest in TCM research in recent years. Nonetheless, there is still no consensus on how to scientifically characterize TCM Q-markers. Our study establishes an identification method for TCM Q-markers based on the analytical hierarchy process (AHP) and the entropy weight comprehensive method. By constructing an evaluation system encompassing the target layer, the factor layer and the control layer, AHP can be used to analyze the weight of three core TCM quality attributes, including effectiveness, testability and specificity. Following that, the entropy weight method is employed to analyze the specific indicators for each attribute based on the literature and experimental data. Finally, the comprehensive weight of each index is obtained by combining the two weights, and the comprehensive weight and the specific value of each component is multiplied and summed to obtain the integrated score ranking, and thereby identify the TCM Q-markers. Taking Shaoyao Gancao decoction as an example, the analysis revealed that the top 8 components are as follows: paeoniflorin > quercetin > albiflorin > glycyrrhizic acid > naringenin > liquiritin > oxypaeoniflorin > benzoylpaeoniflorin, and can be identified as Q-markers of Shaoyao Gancao decoction. This study not only provides support for the establishment of quality standards and process quality control of TCM formulae, but also provides innovative ideas and methods for quantitative evaluation and accurate identification of TCM Q-markers.
ABSTRACT
To study the effect of self-assembled nanoparticles from Shaoyao Gancao Decoction(SGD-SAN) on the encapsulation, in vitro release and intestinal absorption of the main components of Baishao. Particle size analysis and morphological observation were used to verify the formation of SGD-SAN in the decoction. The entrapment efficiency(EE) of SGD-SAN on the main components of Baishao was determined by ultrafiltration centrifugation. The dialysis bag method was used to study the in vitro release of the main components of Baishao with pH 6.8 phosphate buffer solution as the release media. Single-pass intestinal perfusion study was performed to investigate the effect of SGD-SAN on the absorption of the main components of Baishao. The results showed that there were nanoparticles in the SGD, and the particle sizes and PDI of SGD-SAN were about 200 nm and 0.38, respectively. SGD-SAN was irregularly spherical under transmission electron microscope(TEM). The EEs of albiflorin, paeoniflorin and benzoylpaeoniflorin in SGD-SAN were 33.78%±1.03%,33.61%±0.90%,88.53%±0.58%, respectively. The release characteristics of albiflorin, paeoniflorin and benzoylpaeoniflorin from SGD-SAN showed a slow-release effect on pH 6.8 phosphate buffer solution media. SGD-SAN could significantly enhance the absorption of albiflorin, paeoniflorin and benzoylpaeoniflorin in the ileum. The results of this study indicated that SAN could be formed during the mixed decoction of Baishao and Gancao, and SGD-SAN could encapsulate the components of Baishao, with a certain slow-release effect, and the formation of SAN facilitated the absorption of drugs in the ileum.

ABSTRACT
OBJECTIVE@#To investigate the mechanism of cAMP-PKA signaling pathway mediated by Chinese medicine formula Shaoyao Gancao Decoction (, SGD) on the regulation of aquaporin 5 (AQP5) and muscarinic receptor 3 (M3R) levels in Sjögren's syndrome (SS).@*METHODS@#Of the 30 mice, 5 were randomly selected as control, and others were used for creating SS model. After successful modeling, mice were randomly divided into 5 groups (n=5 per group) and intragastrically administered with saline (8 mL/kg), pilocarpine (1.4 mg/kg), or low, medium and high doses SGD (0.14, 0.21, 0.35 g/kg Radix paeoniae with 0.01 g/kg Radix glycyrrhizae, respectively) for 6 weeks. Human labial gland acinar cells were treated with pilocarpine or varying doses of SGD with saline as the placebo. Hematoxylin and eosin staining was used to observe the histopathological changes of the submandibular glands of mice. The serum levels of anti-SS antigen A (SS-A), anti-SS antigen B (SS-B), M3R, and α-fodrin in submandibular glands of mice were measured by enzyme-linked immunosorbent assay. Immunofluorescence staining was used to observe the spatial localization of AQP5 and M3R in acinar cells. Reverse transcriptase polymerase chain reaction and Western blot were used to detect the expressions of PKA, cAMP, Epac1, AQP5, M3R, nuclear factor kappa-B (NF-κB), and tumor necrosis factor (TNF)-α in submandibular gland tissues and cells of each group.@*RESULTS@#Compared to normal mice, body weight, 5-min salivary secretion, 30-min secretion of tears and breakup time of tear film of model mice decreased at 1-6 weeks after immunization (all P<0.05), whereas water intake increased (all P<0.05). In the model group, glands of the submandibular glands showed atrophy, accompanied by acini of different sizes, decreased numbers and loose arrangement, with catheter dilatation and different degrees of lymphocyte infiltration. Conditions of mice in SGD groups were improved. The positive expression of AQP5 and M3R were higher in the acinar cells treated with all doses SGD compared to the normal group; serum levels of SS-A, SS-B, and α-fodrin were lower, and that of M3R was higher in all doses SGD treated animals than the model or pilocarpine treated ones (all P<0.05). Compared to the model and pilocarpine groups, the mRNA and protein levels of NF-κB and TNF-α were lower in mice or cells treated with medium or high-dose SGD (all P<0.05), while those of PKA, Epac1, AQP5 and M3R were higher (all P<0.05).@*CONCLUSION@#SGD can improve symptoms of SS by regulating the cAMP-PKA signaling pathway and increasing AQP5 and M3R levels.

ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effect of Shaoyao Gancao Decoction (, SGD) on the pharmacokinetics of intravenously administered paclitaxel in rats.</p><p><b>METHODS</b>Paclitaxel was intravenously administered to rats (3 mg/kg) with or without the concomitant administration of SGD (752 mg/kg, a single day or 14 consecutive days pretreatment). The paclitaxel in the serum was quantified using a simple and rapid ultra performance liquid chromatography (UPLC) method for the pharmacokinetic study. The pharmacokinetic parameters were calculated via a non-compartment model using the computer program DAS 2.0.</p><p><b>RESULTS</b>The pharmacokinetic parameters of paclitaxel were significantly altered in response to 14 consecutive days of pretreatment with SGD. The area under the curve (AUC, from 4 820±197 to 4 205±186 ng·mL·) and AUC(from 5 237±280 to 4 514±210 ng·mL·) significantly decreased in response to the 14-day pretreatment with SGD. The values of V(L/kg) were 10.74±1.08 and 9.35±0.49, those of CL (L/kg) were 0.67±0.03 and 0.57±0.03 and the t(h) values were 11.17±0.84 and 11.32±0.93, respectively, for the 14-day SGD pretreatment and intravenous paclitaxel alone. The AUCand AUCvalues decreased by 13% and 14% (P<0.01), respectively. The area under the curve decreased signifificantly (P<0.01), and the total clearance increased by 1.2-fold (P<0.01), after 14 consecutive days of pretreatment with SGD. A single-day pretreatment with SGD did not signifificantly affect the pharmacokinetic parameters of paclitaxel.</p><p><b>CONCLUSIONS</b>SGD administration for 14 consecutive days increased the metabolism of paclitaxel, while a 1-day pretreatment had little effect. The results would contribute important information to the study on interaction between Chinese medicines and chemotherapy and also help to utilize SGD better in the adjunctive therapy of cancer patients.</p>

To explore the effects of Shaoyao Gancao decoction on contents of amino acids and expressions of receptors in the brains of spastic paralysis rats, the spastic paralysis rat models of stroke convalescence were made by line tethering method. Baclofen was used as the control group, and the experiment group received Shaoyao Gancao decoction at 3∶1 proportions. After 3 weeks, the neurobehavioral scores, muscular tension and pain threshold were measured and compared. High performance liquid chromatography (HPLC) was used to detect the contents of GABA, Gly, Glu, Asp in cerebral cortex. The protein expressions of GABA receptors Aα1, B； NMDA receptor NR1, NR2A and NR2B in cerebral cortex were determined by immunohistochemistry assay. The results showed that the Shaoyao Gancao decoction at 3∶1 proportion could improve the spastic paralysis state after stroke, significantly improve neurological symptoms (P<0.01), decrease muscular tension (P<0.01) and improve pain threshold (P<0.05) as compared with model group. Simultaneously, the contents of inhibitory amino acids GABA and Gly were increased significantly (P<0.01), while with a decrease tendency in excitatory amino acids Glu and Asp (with no statistical significance). In addition, it could significantly increase the protein expressions of neurotransmitter GABA receptors Aα1, and B (P<0.05); reduce the expressions of neurotransmitter NMDA receptors NR1, NR2A and NR2B (P<0.05). These results suggested that the Shaoyao Gancao decoction at 3：1 proportion could effectively relieve spasm and pain. The mechanism might be associated with increasing the contents of inhibitory amino acids and increasing the expressions of their receptors in spastic paralysis rats after stroke, which would consequently enhance the signal transduction of inhibitory amino acids. Meanwhile, there was a decrease tendency in excitatory amino acids, although no significant effect was observed, and it could suppress the expressions of excitatory amino acids receptors, thus weaken the excitatory signal transduction. Thereby the neurotoxicity was relieved eventually. These findings indicated that Shaoyao Gancao decoction could regulate the balance of neurotransmitter system to relieve the spasticity, and eventually achieve tendon tonifying and spasm relieving effect.
