ETHNOPHARMACOLOGICAL RELEVANCEXiaojin Pills was first recorded during the Qing Dynasty and have a history of nearly 300 years. It is the first choice among Chinese patent medicines for the clinical treatment of diseases of the mammary glands in contemporary traditional Chinese medicine. It was also widely used in the treatment of breast cancer, lung cancer, thyroid cancer, and other malignant tumors. Its initial administration method was "taken orally after soaking with Chinese baijiu"; however, the method was changed to "taken orally with water" within the last 40 years. There is no scientific evidence for the difference in efficacy against breast cancer between the two methods of administration.AIM OF THE STUDYIn vitro and in vivo experiments were carried out to confirm the therapeutic advantages of the liquor extract of Xiaojin Pills to improve the efficacy against breast cancer, and the mechanism was explained in terms of metabolomics and molecular biology.MATERIALS AND METHODSIn vitro, a cell counting kit-8 cell activity assay and flow cytometry were used to detect the activity and apoptosis of MCF-7 breast cancer cells. In vivo, pharmacodynamic evaluation was performed by constructing a heterotopic transplantation model of breast cancer in BALB/c-nu mice. TUNEL staining was used to observe the apoptosis of cells in tumor tissues. The expression of proteins associated with the phosphoinositide 3-kinase (PI3K)/Akt pathway in BALB/c-nu mice tissue was investigated by metabolomics analysis, immunohistochemistry and western blotting.RESULTSCCK-8 assay showed that the IC₅₀ of XJP-L for the inhibition of the activity of MCF-7 cells was less than that of XJP-W at different times. Flow cytometry assay suggested that the apoptosis rate in the XJP-L group was higher than that in the normal control group (p < 0.01). Animal experiment results indicated that both XJP-W group and XJP-L group reduced the volume and quality of the tumor after administration, and the reduction was more significant in the XJP-L group (p < 0.01). Metabolomics analysis results demonstrated that there are about 26 different metabolites have been screened in the serum metabolites between the liquor and water extract, mainly involved in glycerophospholipid, glutamic acid, aspartic acid, nitrogen and pyrimidine metabolism. In addition, immunohistochemistry and WB results showed that compared with the model group, the protein expression of PTEN, AKT, BAX and in tumor tissues of XJP-L and XJP-W groups both exhibited an upward trend, while the expression of BCL-2, p-PI3K and p-AKT exhibited a downward trend, which was much more obvious in XJP-L group.CONCLUSIONSThis study demonstrates that the liquor extract of Xiaojin Pills had a stronger anti-breast cancer effect than that of the water extract. The PI3K/Akt signaling pathway might play an important role in the mechanism of the liquor extract of Xiaojin Pills and thus improve the efficacy against breast cancer.

ETHNOPHARMACOLOGICAL RELEVANCEXiaojin Pills is a classic prescription for the treatment of mammary glands hyperplasia with a history of nearly 300 years, and is also the first choice of Chinese patent medicine for the clinical treatment of mammary glands hyperplasia in contemporary traditional Chinese medicine clinic. Clinical and animal studies have shown that Xiaojin Pills has the effects of anti-mammary glands hyperplasia, promoting blood circulation, anti-inflammation and analgesia. However, its initial administration method was "taking orally after soaked with Chinese Baijiu", the modern method was changed to "taking orally with water" in recent 20 years. Whether there is any difference in the efficacy of the two administration methods is still unknown.AIM OF THE STUDYTo reveal the difference in efficacy and metabolic mechanism of anti-mammary gland hyperplasia between the oral administration of Xiaojin Pills accompanied with Chinese Baijiu (XJP&B) and water (XJP&W).MATERIALS AND METHODSCOX-2 inhibition rate test and anti-platelet aggregation activity test were used to investigate the efficacy difference between the 40 vol% Chinese Baijiu and water extracts of Xiaojin Pills on anti-inflammatory and blood-activating in vitro. Kunming male mice (20 ± 5 g) and SD female rats (200-220 g) were orally treated with XJP&B and XJP&W, respectively. Then the difference in anti-inflammatory and analgesic effects between XJP&B and XJP&W were evaluated via xylene-induced ear swelling test, formaldehyde-induced pain test, and acetic acid-induced writhing test in mice. Determination of nipple diameter, pathological examination of mammary gland tissue, determination of serum E₂, P and FSH content and hemorheological parameters of rats with mammary gland hyperplasia were performed to explore the efficacy difference in anti-mammary gland hyperplasia between XJP&B and XJP&W. Metabolomics was used to study the difference of anti-mammary gland hyperplasia mechanism between XJP&B and XJP&W.RESULTSThe results showed that the effect of XJP&B was superior to that of XJP&W in anti-platelet aggregation, inhibition of inflammation and pain, and anti-mammary gland hyperplasia. Interestingly, the advantages were more significant under low-dose condition. In addition, the mechanism of the two combinations against mammary gland hyperplasia was indeed different. Their common metabolic pathways include tryptophan metabolism and alanine, aspartic acid and glutamic acid metabolism. However, Chinese Baijiu and XJP&B also have additional regulatory effects on linoleic acid metabolic pathway.CONCLUSIONIn brief, this research demonstrated that the efficacy of XJP&B was better than that of XJP&W in activating the blood, anti-inflammation, analgesia and anti-mammary gland hyperplasia, which means that XJP&B has synergistic and superior effects. The special dose-effect relationship under the condition of XJP&B was also found, laying the foundation for clinical treatment to reduce the dosage and shorten the medication cycle, which is beneficial to reduce the economic burden of patients.

Protocatechuic acid is a natural phenolic acid, which widely exists in our daily diet and herbs. It is also one of the main metabolites of complex polyphenols, such as anthocyanins and proanthocyanins. In recent years, a large number of studies on the pharmacological activities of protocatechuic acid have emerged. Protocatechuic acid has a wide range of pharmacological activities including antioxidant, anti-inflammatory, neuroprotective, antibacterial, antiviral, anticancer, antiosteoporotic, analgesia, antiaging activties; protection from metabolic syndrome; and preservation of liver, kidneys, and reproductive functions. Pharmacokinetic studies showed that the absorption and elimination rate of protocatechuic acid are faster, with glucuronidation and sulfation being the major metabolic pathways. However, protocatechuic acid displays a dual-directional regulatory effect on some pharmacological activities. When the concentration is very high, it can inhibit cell proliferation and reduce survival rate. This review aims to comprehensively summarize the pharmacology, pharmacokinetics, and toxicity of protocatechuic acid with emphasis on its pharmacological activities discovered in recent 5 years, so as to provide more up-to-date and thorough information for the preclinical and clinical research of protocatechuic acid in the future. Moreover, it is hoped that the clinical application of protocatechuic acid can be broadened, giving full play to its characteristics of rich sources, low toxicity and wide pharmacological activites.
