ObjectiveTo investigate the quality markers of Xiaoqinglong granules（XQLG） for treating bronchial asthma using the analytic hierarchy process（AHP）-entropy weight method（EWM）， network pharmacology and high performance liquid chromatography（HPLC） content determination. MethodsEffectiveness， testability and peculiarity component data of XQLG in treating bronchial asthma were constructed through database retrieval， literature review， and network pharmacology. Subsequently， AHP-EWM was used to quantitatively identify and weight the control layer and element layer， the relevant compounds were selected as candidate quality markers based on comprehensive scores. Further comparison of reference substances and establishment of HPLC content determination method were used to determine the potential quality markers of XQLG， which were verified by molecular docking with disease targets. ResultsA total of 13 components， including glycyrrhizic acid， paeoniflorin， schisandrol A， isoliquiritigenin， 6-gingerol， ephedrine， liquiritin， albiflorin， liquiritigenin， 6-shogaol， pseudoephedrine， cinnamic acid and cinnamaldehyde， were identified as potential quality markers of XQLG by AHP-EWM. Quantitative analysis indicated that all aforementioned quality markers could be detected in 13 batches of XQLG， indicating that it had stable testability as a quality marker. Among these 13 batches of samples， ephedrine and paeoniflorin exhibited good consistency in content， while pseudoephedrine and cinnamaldehyde showed poor consistency. Molecular docking analysis revealed that the 13 compounds exhibited binding energies with the core targets -2.11 kcal·mol^-1， indicating that the 13 compounds could spontaneously bind to the disease targets， which may be the material basis for the treatment of bronchial asthma with XQLG. ConclusionIn this study， 13 compounds were screened by AHP-EWM combined with network pharmacology and HPLC as quality markers for the treatment of bronchial asthma by XQLG， laying the foundation for enhancing the quality standards of this preparation.

In this study, potential quality markers(Q-markers) of Schisandrae Chinensis Fructus for treating bronchial asthma were predicted based on analytic hierarchy process(AHP), entropy weight method(EWM), fingerprint, and network pharmacology. AHPEWM was employed to quantitatively identify the Q-markers of Schisandrae Chinensis Fructus. AHP was used to weight the primary indicators(effectiveness, measurability, and specificity), while EWM was employed to analyze the secondary indicators of each primer indicator. Further, through fingerprint combined with network pharmacology, a ″component-target-pathway″ network was constructed to screen the components of Schisandrae Chinensis Fructus for treating bronchial asthma. It was finally determined that schisandrol A,schisandrin A, and schisandrin B were potential Q-markers of Schisandrae Chinensis Fructus in the treatment of bronchial asthma. This study is the first to comprehensively use AHP-EWM, fingerprint, and network pharmacology to screen the key Q-markers of Schisandrae Chinensis Fructus in the treatment of bronchial asthma. This study provides a scientific basis for improving the quality standard of Schisandrae Chinensis Fructus and lays a foundation for studying its material basis in treating bronchial asthma.

Background: Viral hepatitis causes annual deaths of 1.4 million people. Antiviral therapy rarely cures the disease, and patients are usually required to maintain lifelong medication, leading to cumulative drug toxicity. Schisandrae Fructus (SF) is efficacious in the treatment of viral hepatitis. Objective: The systematic review and meta-analysis aim to examine the efficacy and safety of SF alone or in combination with specific and nonspecific treatments for treating viral hepatitis by analyzing the clinical trials performed up to date. Methods: An extensive literature was searched in 7 databases from inception to May 2023. Final outcomes were divided into the primary outcomes containing the total effective rate and virological responses, as well as the secondary outcomes containing liver biochemical functions and frequencies of adverse events. RevMan 5.3 and GRADE pro 3.6 software were used for meta-analysis and assessment of evidence quality. Subgroup analysis was conducted to explore the source of the heterogeneity. Results: Twenty-nine randomized controlled trials were included in the meta-analysis. SF treatment was comparable with western medicines or other traditional Chinese treatments in terms of primary and secondary outcomes. In combination with specific treatments with antiviral medicines, SF group reduced 18.45 U/L of alanine aminotransferase levels [weighted mean difference: 18.45, 95% confidence interval (CI): (16.12, 20.78), p < 0.000 01] and 8.37 U/L of aspartate aminotransferase levels [weighted mean difference: 8.37, 95% CI: (1.25, 15.48), p = 0.02], and it decreased the levels of hyaluronic acid (HA) [standard mean difference (SMD): 0.92, 95% CI: (0.58, 1.27), p < 0.000 01], laminin (LN) [SMD: 0.64, 95% CI: (0.38, 0.90), p < 0.000 01], and procollagen type III [SMD: 0.48, 95% CI: (0.28, 0.67), p < 0.000 01], while increasing the total effective rate by 24% [risk ratio: 1.24, 95% CI: (1.15, 1.32), p < 0.000 01]. There were no severe adverse events during treatment. Conclusions: SF was a potential adjuvant for antiviral therapy in restoring liver function. However, the poor quality of the included randomized controlled trials limited the recommendations. More long-term, randomized, and double-blind studies should be performed to assess the efficacy and safety of combination therapy.

Aesculus chinensis is an important medicinal and horticultural plant. Its dried mature seeds, known as "Suoluozi", are a well-known traditional Chinese medicine. Aescins are its main active components, possessing multiple pharmacological activities such as anti-inflammatory and anti-exudative effects. They are widely used in the treatment of diseases such as lumbar disc herniation, postoperative edema, and sports injuries, leading to a continuous increase in market demand in recent years. The DNA binding with one finger(Dof) family is a unique transcription factor family found in the plant kingdom. It plays a crucial role in plant growth, development, stress responses, and regulation of secondary metabolism. However, research on the Dof gene family in A. chinensis is relatively scarce. In this study, we identified 36 AcDof genes from the genome of A. chinensis and analyzed their physicochemical properties, chromosomal localization, phylogenetic relationships, gene structures, cis-acting elements, and expression patterns in different tissues. The results showed that AcDof proteins ranged from 81 to 493 amino acids in length, with molecular weights ranging from 9 270.38 to 55 015.68 and isoelectric points ranging from 4.84 to 10.2. The subcellular localization analysis revealed that 34 AcDof proteins were located in the nucleus, while the remaining two AcDof proteins were located in the chloroplasts. Phylogenetic analysis divided AcDofs into nine subgroups, and gene structure analysis indicated that all AcDof genes possessed a C2-C2 type single zinc finger domain. Gene expression analysis using transcriptome data revealed tissue-specific expression patterns among AcDof family members. Specifically, AcDof04, AcDof02, and AcDof03 exhibited specific expression in seeds, suggesting their potential involvement in the regulation of aescin biosynthesis. This study not only enhances our understanding of the Dof gene family in A. chinensis but also provides important genetic resources for further investigation of the functions and regulatory mechanisms of Dof genes in this species.

ObjectiveTo establish a rapid screening method for germplasm materials of Gastrodia elata with high purity， and lay a foundation for pure line breeding and cross breeding. MethodBased on the whole genome sequencing and population resequencing of G. elata， 20 restriction fragment length polymorphism (RFLP) markers were developed by single nucleotide polymorphism (SNP) sites. The polymerase chain reaction (PCR)-RFLP method was used to carry out restriction endonuclease experiments on 20 RFLP markers of 15 G. elata germplasms. According to the number of enzymatic bands at 20 RFLP marker sites, the purity of 15 germplasms was calculated and evaluated. On this basis, genome resequencing technology was used to verify the assessment results. ResultTen germplasm materials with purity greater than 95% were screened out by PCR-RFLP method， 3 of which had 95% purity and 7 had 100% purity. Nine germplasm materials with purity greater than 95% were screened out by genome resequencing methods, and 8 of them were consistent with the results of PCR-RFLP. ConclusionThe PCR-RFLP method established in this study for screening G. elata germplasms with high purity precision of RFLP markers has 80% precision and 89% accuracy. The method is simple， efficient， and significantly less expensive than genome resequencing method, which provides technical support for pure line breeding of G. elata and references for breeding of other Chinese medicinal materials.

Huangpu Tongqiao Capsules(HPTQC), with the functions of invigorating Qi and kidney, eliminating phlegm and removing blood stasis, have the effect of treating Alzheimer's disease(AD), but its mechanism needs further exploration. To explore the relationship between the therapeutic mechanism of HPTQC on Alzheimer's disease and EGFR-PLCγ signal pathway, 40 healthy male SD rats were selected and divided into 4 groups randomly: sham operation group(sham), model group(model), HPTQC group(HPTQC), and nimodipine group(NMP). AD rat model was established by intraperitoneal injection of D-galactose combined with an intracerebral injection of amyloid-β peptide(25-35). After 28 days of administration, Morris water maze test and HE staining showed that the learning and memory ability of AD rats were significantly decreased(P<0.01), and hippocampal neurons were obviously da-maged. However, HPTQC could improve the learning and memory ability of AD rats(P<0.05) and reduce the damage of hippocampal neurons. Immunofluorescence test results showed that the expression levels of EGFR and p-Tau in hippocampal CA1 region of AD rats were significantly increased(P<0.01), and HPTQC could reduce the expression of EGFR and p-Tau in hippocampus of AD rats(P<0.01). Western blot results showed that the protein expression levels of EGFR, PLCγ, IP3 R and p-Tau in hippocampus of AD rats were significantly increased(P<0.01), and HPTQC could reduce the protein expression of EGFR, PLCγ, IP3 R and p-Tau in AD rats(P<0.05). RT-PCR results showed that the mRNA levels of EGFR, PLCγ, IP3 R and Tau in hippocampus of AD rats were significantly increased(P<0.01), and HPTQC could reduce the mRNA levels of EGFR, PLCγ, IP3 R and Tau in AD rats(P<0.05). The results indicate that HPTQC can improve the learning and memory ability of AD rats, and its mechanism of action may be related to regulating EGFR-PLCγ signal pathway.

To better understand the formation mechanism of Gastrodia elata traits, the agronomic traits of aboveground tissues and tubers were measured and analyzed in this study. It has shown that the color and thickness of the stems of the 39 samples of the G. elata collected are affected by the germplasm and variation. Clustering analysis of 39 agronomic traits of G. elata was conducted with Ward's method and Euclidean distance. The threshold of 11.0 was divided into three groups, namely hybrid G. elata, G. elata f. elata and G. elata f. glauca. Simultaneously, the correlation analysis, coefficient of variation analysis, factor analysis and cluster analysis of 13 agronomic traits of 105 G. elata tuber samples were carried out. The results showed that the weight of G. elata was significantly positively correlated with tuber length and width. The agronomic traits of tuber were highly variable, and the depth of variability of the scar was the largest and 13 agronomic traits could be divided into 6 types of factors and the contribution up to 89.348%, furthermore, tuber length factor, width and weight factor contributed more than 20%, indicating that it is of great significance for distinguishing G. elata germplasm. Cluster analysis was performed by Ward's method and Euclidean distance, with 8.0 as the threshold can be divided into three categories in the light of the origin of the source, 33 samples from Shanxi and Hubei are clustered into one category, and 19 samples from Yunnan and Guizhou are clustered into one group, and the remaining samples are grouped into one category. This study will provide a basis for the identification and purification of G. elata germplasm and germplasm resources.
