[Standardization system of industry decoction pieces based on whole process quality control concept].
Traditional Chinese medicine (TCM) decoction pieces refer to prescription drugs that can be used in clinical or preparation production after processing medicinal herbs. TCM decoction pieces industries are inherited from the culture of TCM and are important because of their independent intellectual property rights. The Chinese Pharmacopoeia (Ch. ⋯ Aiming at the existing problems of the TCM decoction pieces industry, this article was guided by the standardization system of TCM based on the concept of whole-process quality control, combined with the reference to the Japanese Kampo medicine industry's feeding mode and the reflection on the combination of traditional Chinese medicine processing and modern industry, as well as the study of the core law of the whole-process of TCM production, etc. Industrial decoction pieces and the idea of building a standardized system of TCM industry decoction pieces based on the whole-process quality control were discussed in this paper, which can provide insights for exploring the effective fusion between TCM processing theory and classic heritage and modern manufacturing and can provide the basis for the establishment of a standardized system for industrial decoction pieces based on whole-process quality control of TCM. It can also offer reference for the development of the advantages of geo-authentic crude drug and the establishment of high spots of industry decoction pieces.

Review[Research progress on pharmacological effects of separation and combination methods based on traditional Chinese medicine property and flavor].
The theory of medicinal properties of traditional Chinese medicine (TCM) is one of the core theories of TCM, which is an important basis for guiding the clinical application of TCM and the key supporting point for the modernization of TCM. How to study the modernization of TCM under the guidance of traditional Chinese medicine theory has become a great challenge for modern researchers. Currently, the researches in TCM mainly focus on chemical studies such as on active ingredients and effective components, lacking the guidance of traditional Chinese medicine theory, and losing the inherent characteristics of TCM. ⋯ The property and flavor of TCM are closely related to its chemical compositions, and also have certain regularity. The researches on the chemical components of TCM, systematic design of property and flavor, as well as the separation and combination of TCM property and flavor are beneficial to the overall analysis of the characteristics of TCM, showing great significance to inherit and carry forward TCM. The pharmacological effects about separation and combination methods based on TCM property and flavor were reviewed in this study, providing theoretical reference for the development of new drugs and the application of TCM.

Randomized Controlled Trial[Procalcitonin impact analysis, respiratory function and blood gas analysis on Xiaoqinglong decoction combined with non-invasive ventilation in treatment of AECOPD patients].
To observe the effect of Xiaoqinglong decoction combined with noninvasive ventilation on procalcitonin (PCT), blood gas analysis and respiratory functions in acute exacerbation of chronic obstructive pulmonary disease in the elderly (AECOPD), and investigate its correlation and clinical significance. Eighty-four elderly AECOPD patients with respiratory failure in our hospital from January 2015 to October 2017, were randomly divided into control group and observation group, 42 cases in each group. The control group received western medicine combined with noninvasive ventilator therapy, and the patients in observation group additionally received Xiaoqinglong decoction on the basis of the treatment in control group. ⋯ There were no statistically significant differences in PCT, PaO₂, PaCO₂, FVC, FEV1/FVC, FEV1, and TCM syndrome scores between two groups before treatment. But after treatment, PCT and PaCO₂ levels in the observation group were lower and PaO₂, FVC, FEV1/FVC, FEV1 levels was higher than those in the control group (P<0.05); TCM syndrome scores were lower than those in the control group (P<0.05); both groups had no obvious adverse reactions. The results showed that Xiaoqinglong decoction combined with noninvasive ventilator could significantly reduce the procalcitonin level, effectively improve the respiratory function and blood gas analysis indexes, and significantly reduce the clinical symptoms in AECOPD patients, so it is worthy of promotion.

[Analysis of traditional Chinese medicine prescriptions based on support vector machine and analytic hierarchy process].
Combined use of drugs is a hot spot in the research of new drugs nowadays, and traditional Chinese medicine (TCM) is a classic practice in the combined use of drugs. In this paper, the compatibility of TCM prescriptions and the related properties of composed herbs were calculated and studied to verify and discuss the feasibility of the results in guiding compatibility. Research Group on New Drug Design, Institute of Chinese Materia Medica, China Academy of Chinese Medical Sciences had established a structured database of TCM prescriptions by using traditional Chinese medicine inheritance support system (TCMISS V2.0), including 4 012 prescription compatibilities, 2 072 drug components, 381 kinds of TCM diseases, 316 kinds of TCM syndromes and 26 kinds of drug properties. ⋯ The computational results showed that the accuracy in efficacy prediction of two data sets, i.e. prescription-disease and prescription-syndrome, was up to 90% in the linear SVM model. The macro₋averaging and micro₋averaging of the two models were around 0.92, 0.46, respectively. After AHP mapping, most of the incompatible combinations showed significant difference with other drug combinations during the clustering process in the vertical icicle, indicating that the proper machine learning algorithm can be used to lay the foundation for further exploring the combination rules in TCM and establishing more detailed drug-disease and syndrome predicting models, and provide theoretical guidance for the study of the combined use of drugs to a certain degree.

[Effect of Xianling Gubao capsule on bone metabolism in ovariectomized rats].
To investigate the effect of Xianling Gubao capsule in preventing postmenopausal osteoporosis, forty-eight female Wistar rats were randomly divided into four groups: sham group (Sham), ovariectomized group (OVX), ethinylestradiol group (EE) and Xianling Gubao capsule group (XLGB). Rats in each group received ovariectomy, except for sham group. The XLGB group received Xianling Gubao capsule at the dose of 378 mg·kg⁻¹·d⁻¹. ⋯ There was no significant change in femoral cortical bone between the two groups. Xianling Gubao capsule can prevent osteoporosis in ovariectomized rats. The possible mechanism is the dual activity of inhibiting bone resorption and improving bone formation.
