[Study on mechanism of "Epimedii Folium-Paeoniae Radix Alba" in treatment of lumbar disc herniation based on network pharmacology].
The aim of this paper was to investigate the key targets and mechanism of "Epimedii Folium-Paeoniae Radix Alba" in the treatment of lumbar disc herniation by means of network pharmacology. The currently recognized databases and analysis software at home and abroad were used to construct the network from drugs and diseases. The chemical components of Epimedii Folium and Paeo-niae Radix Alba were collected by using databases such as TCMSP, while their active components were determined and the action targets were predicted according to threshold screening and literature reports. ⋯ Through KEGG pathway enrichment analysis, 91 signaling pathways related to inflammation, metabolism, and senescence were identified, mainly including IL-17 signaling pathway and TNF signaling pathway and so on. "Epimedii Folium-Paeoniae Radix Alba" showed the characteristics of multi-channel and multi-target for the treatment of lumbar disc herniation. This study preliminarily explored the key targets for its role and the biological processes and signaling pathways involved. It was found that it may play a therapeutic role by affecting inflammation and immune regulation, which laid the foundation for further experimental verification.

[Mechanism of "unification of drugs and excipients" for Chinese medicine semi-extract based on powder compression behavior analysis].
In this paper, five representative Chinese herbal decoction pieces of Scutellariae Radix, Paeoniae Radix Alba, vinegar-processed Corydalis Rhizoma, Polygoni Multiflori Radix Praeparata and Lonicerae Japonicae Flos were selected to prepare the corresponding fine powder of pieces, extract powder, semi-extract powder and physical mixed powder. The physical properties of 20 kinds of powders, such as related parameters of particle size, density, stability and flowability, were evaluated comprehensively. The compression curves of powder porosity and tensile strength changing with pressure were plotted, and the Heckel equation and the Kawakita equation were used to describe the powder compression behavior. ⋯ Principal component analysis(PCA) was carried out on the 17 physical attributes and 5 compression parameters of the powder. It was found that the first principal component mainly reflected the differences among the material sources, while the second principal component could reflect the differences among fine powder of pieces, extract powder, semi-extract powder and physical mixed powder originating from the same Chinese herbal decoction pieces. In this paper, the mechanism of "unification of drugs and excipients" of Chinese medicine semi-extract powder was explained in terms of physical properties and compression behavior of powders, which provided reference for the formulation design and process development of Chinese medicine tablets.

Meta Analysis[Efficacy of Shensong Yangxin Capsules in treating bradycardia combined with premature beat: a systematic review and Meta-analysis of randomized clinical trials].
To analyze the efficacy and safety of Shensong Yangxin Capsules in treatment of bradycardia combined with premature beat. Databases, such as CNKI, VIP, WanFang, SinoMed, PubMed, Cochrane Library, ClinicalTrials were retrieved by computers for relevant randomized controlled trials of Shensong Yangxin Capsules in treatment of bradycardia combined with premature beat. Two researchers independently screened out the literatures, extracted data according to the inclusion criteria, and applied the Risk of Bias assessment tool in assessing the methodological quality. ⋯ In conclusion, the single administration with Shensong Yangxin Capsules may have a certain effect in improving heart rate, controlling premature beats and alleviating clinical symptoms in patients with bradycardia combined with premature beat, with no obvious adverse reaction. Shensong Yangxin Capsules can be used in clinic. This potential conclusion needs to be confirmed in future trials using rigorous methodology.

Meta Analysis[Network Meta-analysis of effect of traditional Chinese medicine injections in adjuvant treatment of mycoplasma pneumonia in children].
To assess the clinical efficacy of traditional Chinese medicine injection for adjuvant treatment of mycoplasma pneumoniae pneumonia in children by network Meta-analysis method. We retrieved CNKI, WanFang, CBM, Cochrane Library, PubMed from the establishment to September 2018. Two reviewers independently screened out literatures, extracted data and assessed the methodological quality of included studies. ⋯ According to the results of network Meta-analysis, the order by the total effective rate from high to low was Huangqi Injection>Xiyanping Injection>Tanreqing Injection>Compound Danshen Injection>Reduning Injection>Yanhuning Injection>Qingkailing Injection>Xixinnao Injection; the order by cooling time from high to low was Reduning Injection> Yanhuning Injection>Qingkailing Injection>Tanreqing Injection>Huangqi Injection>Xiyanping Injection>Xiexinnao Injection>Compound Danshen Injection; the order by the cough disappeared time from high to low was Compound Danshen Injection>Qingkailing Injection>Xiyanping Injection>Huangqi Injection>Yanhuning Injection>Reduning Injection>Tanreqing Injection>Xixinnao Injection; the order by the rales disappearing time from high to low was Qingkailing Injection>Yanhuning Injection>Reduning Injection>Huangqi Injection>Tanreqing Injection>Xiyanping Injection>Xixinnao Injection. The results show that traditional Chinese medicine injection has a significant clinical efficacy in the adjuvant treatment of various symptoms of mycoplasma pneumoniae pneumonia in children. Due to the small sample size, more studies are required to verify the strength of evidence.

[Predictive model for hygroscopicity of contents in Guizhi Fuling Capsules].
To control the risks of powder caking and capsule shell embrittlement of Guizhi Fuling Capsules, a predictive model for hygroscopicity of contents in Guizhi Fuling Capsules was built. A total of 90 batches of samples, including raw materials, intermediate powders and capsules, were collected during the manufacturing of Guizhi Fuling Capsules. According to the production sequence, 47 batches were used as the calibration set, and the properties of raw materials and the four intermediate powders were comprehensively characterized by the physical fingerprint. ⋯ The prediction model established with the two CMAs as independent variables had an average relative prediction error of 2.68% for samples in the validation set, indicating a good accuracy of prediction. This paper proved the feasibility of predictive modeling toward the control of critical quality attributes of Chinese medicine oral solid dosage(OSD). The combination of the continuous quality improvement, the industrial big data and the process modeling technique paved the way for the intelligent manufacturing of Chinese medicine oral solid preparations.
