RESUMEN
Heishunpian is obtained through complex processing of Aconiti lateralis radix praeparata. However, the impact of each processing step on chemical compositions and pharmacological activities is still unclear. The mechanism of the processing needs to be further studied. The samples were all prepared using the "step knockout" strategy for UPLC-QTOF-MS analysis, and analgesic and anti-inflammatory efficacy evaluation. Each sample was analyzed by UPLC-QTOF-MS to determine the component differences. The hot plate test and acetic acid writhing test were used to evaluate the analgesic effect. Anti-inflammatory efficacy was evaluated by xylene-induced ear edema test. The correlation between components and efficacies was studied to screen the effective components for further investigating the processing of Heishunpian. Mass spectrum analysis results showed that 49 components were identified, and it appeared that brine immersion and rinsing had a great influence on the components. In the hot plate test, ibuprofen and Heishunpian had the most significant effect, while ibuprofen and the sample without rinsing showed the best efficacy for the acetic acid writhing test. The sample without dyeing had the best effect on ear edema. The correlation analysis indicated that mesaconine, aconine, 3-deoxyaconine, delbruine, and asperglaucide were potentially considered effective analgesic components. It is not recommended to remove brine immersion and rinsing. Boiling and steaming are necessary processes that improve efficacy. Dyeing, which does not have a significant impact on components and efficacy, may be an unnecessary process. This research has been of great significance in identifying anti-inflammatory and analgesic components and optimizing processing for Heishunpian.

Qingpi, a well-known traditional Chinese medicine for qi-regulating and commonly processed into three types of pieces, has been widely used in the clinical application of liver disease for thousands of years. In this study, an ultra-high-performance liquid chromatography-quadrupole-time of flight-mass spectrometry approach along with multivariate statistical analysis was developed to assess and characterize the differentiations of three processed products and confirm the potential quality markers of Qingpi. In addition, a systematic analysis combined with network pharmacology and molecular docking was performed to clarify the potential mechanism of Qingpi for the treatment of liver disease. As a result, 18 components were identified and an integrated network of Qingpi-Components-Target-Pathway-Liver Disease was constructed. Eight compounds were finally screened out as the potential quality markers acting on ten main targets and pathways of liver disease. Molecular docking analysis results indicated that the quality markers had a good binding activity with the targets. Overall, this work preliminarily identified the potential quality markers of three processed products of Qingpi, and predicted its targets in the prevention and treatment of liver disease, which can provide supporting information for further study of the pharmacodynamic substances and mechanisms of Qingpi.

The processing of Chinese medicine is a unique and dialectical treatment of traditional Chinese medicine in clinic.The processing theory of "leading vinegar-processing Chinese medicine into liver" is one of the traditional processing theories of Chinese medicine.The vinegar-processing Chinese medicine under the guidance of the processing theory typically reflects the characteristics of "reducing toxicity and enhancing efficacy" of the processing of Chinese medicine.This paper traced the origin and discussed the connotation of the traditional theory of "leading vinegar-processing Chinese medicine into liver".Combined with the research status of "lea-ding vinegar-processing Chinese medicine into liver", this paper explored the mechanism of "leading vinegar-processing Chinese medicine into liver" from the aspects of material basis, medicine effect, and traditional Chinese medicine(TCM) meridian, and analyzed the existing problems in the current research.This paper reviewed the modern study on reducing toxicity and enhancing efficacy of vinegar-processing Chinese medicine, and deeply explored the scientific connotation of the traditional processing theory of "leading vinegar-processing Chinese medicine into liver".At the same time, the research trend and idea of the effect mechanism of "leading vinegar-processing Chinese medicine into liver" based on the Quality markers(Q-Marker) of TCM, biological targets, and clinical prescriptions were put forward, providing references for the further study on "leading vinegar-processing Chinese medicine into liver".This paper also provided a scientific basis for the rational selection of processed products in TCM clinical practice.

Triclosan (TCS) is a broad spectrum antimicrobial agent which has been widely dispersed and determinated in the aquatic environment. However, the effects of TCS on reproductive endocrine in male fish are poorly understood. In this study, male Yellow River carp (Cyprinus carpio) were exposed to 0, 1/5, 1/10 and 1/20 LC50 (96 h LC50 of TCS to carp) TCS under semi-static conditions for 42 d. Vitellogenin (Vtg), 17ß-estradiol (E2), testosterone(T), gonadotropin (GtH), and gonadotropin-releasing hormone (GnRH) levels were measured by enzyme-linked immunosorbent assay (ELISA). Meanwhile, we also examined the mRNA expressions of aromatase, GtHs-ß, GnRH, estrogen receptor (Er), and androgen receptor (Ar) by quantitative Real-time Polymerase Chain Reaction (qRT-PCR). TCS induced Vtg levels of hepatopancreas, E2 levels of serum, and inhibited Ar and Er mRNA levels, suggesting that the induction of Vtg production by TCS was indirectly caused by non-Er pathways. TCS-induced Vtg levels by interfering with the reproductive axis at plenty of latent loci of male carps: (a) TCS exposure increased the aromatase mRNA expression of hypothalamus and gonad aromatase, consequently increasing serum concentrations of E2 to induce Vtg in hepatopancreas; (b) TCS treatment changed GtH-ß and GnRH mRNA expression and secretion, causing the disturbance of reproductive endocrine; (c) TCS exposure decreased Ar mRNA levels, indicating potential Ar-mediated antiandrogen action. These mechanisms showed that TCS may induce Vtg production in male carp by non-Er-mediated pathways.

OBJECTIVE: To evaluate the protective effects of punicosides on alcohol induced acute liver injury in mice and its possible mechanisms as well. METHOD: The 60 mice were randomly divided into normal control, model group, three dose groups of punicosides with low, medium and high, then there is silibinin group. Three dose groups of punicosides and silibinin were given in advance by gavage for 4 weeks, then the mouse model of alcoholic acute liver injury was established. The serum levels of ALT, AST and TG were determined, and the mice were killed to calculate somatic index of liver, thymus as well as spleen. MDA, SOD, GSH-Px and GSH-ST were detected in the liver homogenate. Histopathological changes of the liver were observed by HE staining. The expression of MCP-1 and NF-kappaB in the liver tissues were detected by immunohistochemistry. RESULT: Mid and high dose of punicosides reduced the liver index in mice significantly, improved liver steatosis, decreased the level of ALT, AST and TG in serum and the content of MDA in liver homogenate, furthermore the two dose groups increased the activity of SOD, GSH-Px and GSH-ST, inhibited the expression of MCP-1 and NF-kappaB in liver tissue. CONCLUSION: Punicosides can protect the acute liver damage induced by alcohol.
