The effects of Jingui Shenqi Pills(Jingui) and Liuwei Dihuang Pills(Liuwei) which respectively tonify kidney Yang and kidney Yin on brain function have attracted great attention, while the differences of protein expression regulated by Jingui and Liuwei remain to be studied. This study explored the difference of protein expression profiles in the hippocampi of mice orally administrated with the two drugs for 7 days. The protein expression was quantified using LC-MS/MS. The results showed that among the 5 860 proteins tested, 151, 282 and 75 proteins responded to Jingui alone, Liuwei alone, and both drugs, respectively. The ratio of up-regulated proteins to down-regulated proteins was 1.627 in Jingui group while only 0.56 in Liuwei group. The proteins up-regulated by Jingui were mainly involved in membrane transport, synaptic vesicle cycle, serotonergic synapse, dopaminergic synapse and so on, suggesting that Jingui may play a role in promoting the transport of neurotransmitter in the nervous system. The proteins down-regulated by Liuwei were mainly involved in membrane transport, synapse, ion transport(potassium and sodium transport), neurotransmitter transport, innate and acquired immune responses, complement activation, inflammatory response, etc. In particular, Liuwei showed obvious down-regulation effect on the members of solute carrier(SLC) superfamily, which suggested that Liuwei had potential inhibitory effect on membrane excitation and transport. Finally, consistent results were obtained in the normal mouse and the mouse model with corticosterone-induced depressive-like behavior. This study provides an experimental basis for understanding the effect of Jingui and Liuwei on brain function from protein network.

To establish the quantitative analysis multi-components with a single-marker(QAMS) method for six components and fingerprint of standard decoction of Gastrodiae Rhizoma, verify the accuracy and feasibility of the method, and evaluate the quality of standard decoction. Based on UPLC with gastrodin as the internal standard, relative correction factors of p-hydroxybenzyl alcohol, parishin E, parishin B, parishin C, parishin A and gastrodin were determined by investigating the column temperature, flow rate, chromatographic columns and multi-point concentration correction. The total contents in 18 batches of standard decoction of Gastrodiae Rhizoma and the similarity were determined to calculate the similarity. The results of standard curve method, external standard one-point method and quantitative analysis multi-components with a single-marker(QAMS) were compared, and the results showed that there was no significant difference among these three methods. By analyzing the results of standard decoctions from different origins, it can be seen that the quality of Gastrodia standard decoctions derived from Anhui and Yunnan was better, followed by Shaanxi and Hubei, and relatively poor in Gansu, with similarities all above 0.90 in the fingerprints. Therefore, the QAMS method that can measure the contents of gastrodin, p-hydroxybenzyl alcohol, parishin E, parishin B, parishin C and parishin A in standard decoction of Gastrodiae Rhizoma combined with fingerprint is accurate, feasible and fast, which can be used to evaluate the quality of standard decoction of Gastrodiae Rhizoma, and also provide a reference for the research on the quality standards of raw materials for Gastrodiae Rhizoma prepared slices and alike.

OBJECTIVE: To explore the anti-nociceptive effect of patchouli alcohol (PA), the essential oil isolated from Pogostemon cablin (Blanco) Bent, and determine the mechanism in molecular levels. METHODS: The acetic acid-induced writhing test and formalin-induced plantar injection test in mice were employed to confirm the effect in vivo. Intracellular calcium ion was imaged to verify PA on mu-opioid receptor (MOR). Cyclooxygenase 2 (COX2) and MOR of mouse brain were expressed for determination of PA's target. Cellular experiments were carried out to find out COX2 and MOR expression induced by PA. RESULTS: PA significantly reduced latency period of visceral pain and writhing induced by acetic acid saline solution (P<0.01) and allodynia after intra-plantar formalin (P<0.01) in mice. PA also up-regulated COX2 mRNA and protein (P<0.05) with a down-regulation of MOR (P<0.05) both in in vivo and in vitro experiments, which devote to the analgesic effect of PA. A decrease in the intracellular calcium level (P<0.05) induced by PA may play an important role in its anti-nociceptive effect. PA showed the characters of enhancing the MOR expression and reducing the intracellular calcium ion similar to opioid effect. CONCLUSIONS: Both COX2 and MOR are involved in the mechanism of PA's anti-nociceptive effect, and the up-regulation of the receptor expression and the inhibition of intracellular calcium are a new perspective to PA's effect on MOR.

The PK-PD correlation models by using pharmacodynamics and pharmacokinetics were applied to study the material basis of Naomaitong,a clinical empirical prescription for the treatment of cerebral apoplexy,in inhibiting the death of PC12 nerve cells induced by Na_2S_2O_4 and Glu. In this experiment,PC12 cell death models induced by Na_2S_2O_4 and Glu were established respectively.With LDH lateral leakage and NO content as pharmacodynamic indexes,PK-PD model was established by SVM algorithm to evaluate the effective components of Naomaitong in inhibiting neural cell death. The results showed that the positive correlation of emodin methyl ether-8-O-β-D-glucopyranoside,aloe emodin,chrysophanol,rhein,emodin,ginsenoside Rg1,ginsenoside Rc,3'-methoxypuerarin and ligustilide was significant,obviously improving the LDH release and NO content. The results indicated that the contribution of Radix Puerariae Lobatae Radix and Rhei Radix et Rhizoma in Naomaitong could protect the nerve cell death induced by Na_2S_2O_4 and Glu respectively. PK-PD model was used to screen the neuroprotective components in Naomaitong,revealing the possible pharmacodynamic material basis of Naomaitong in the treatment of cerebral ischemia injury.

Objective: To discuss the effect of herbal compatibility on the components of volatile oils in Menthae Haplocalycix Herba and Schizonepetae Herba,and the comparison of the anti-bacterial effects in vitro,in order to provide the experimental basis for investigating the effective material basis of their herb-pair. Method: Steam distillation was used to extract volatile oils of Menthae Haplocalycix Herba, Schizonepetae Herba,and their combination. GC-MS was employed to analyze their volatile oils,and the anti-bacterial effects in vitro were compared. Result: Totally 50 compounds were identified from the volatile oils of Menthae Haplocalycix Herba;41 compounds were identified from the volatile oils of Schizonepetae Herba;and 60 compounds were identified from the volatile oils of their herbal pairs. A total of 27 common compounds were found in the samples of three volatile oils. Totally 5 new compounds were detected in the volatile oils of their herbal pairs,and 9 compounds were not detected. In vitro,volatile oils of both their herbal pairs and individual herbs had bacteriostatic effects on dung Enterococcus (ATCC2922),Staphylococcus aureus (ATCC2923),Escherichia coli (ATCC35218),and E. coli (ATCC25922). Among them,volatile oils of their herbal pairs had stronger bacteriostatic effects on dung enterococcus (ATCC2922) and staphylococcus aureus (ATCC2923) than volatile oils of individual herbs. Moreover,the order of the inhibitory effects of volatile oils on E. coli (ATCC35218 and ATCC25922) were "herbal pairs=peppermint > herba schizonepetae". Conclusion: There were some changes between the volatile oils of individual herbs and the volatile oils of their herbal pairs. These phenomena may be caused by the occurrence of certain chemical reactions and physical changes in compatibility of decocting process. The antibacterial effects of volatile oils of their herbal pairs were better than those of individual herbs in vitro.
RESUMEN
In our study, we have established a novel liquid-driven co-flow focusing (LDCF) process to fabricate curcumin (CUR)-loaded poly (lactic-co-glycolic acid) (PLGA) microparticles (CPMs). LDCF-CPMs of size 20.26 ± 2.37 µm have high encapsulation efficiency (>70%) and were intended for application in ovarian cancer by intraperitoneal (IP) administration. LDCF-CPMs have smooth surface with narrow size distribution and a core-shell structured verified by confocal microscopy which can be precisely controlled by changing the flow rates of focusing, outer and inner phases. The LDCF-CPMs reveal the physiochemical stability with sustained release profile corresponding to 95% CUR release over a period of 14 days in an in vitro release medium. Moreover, LDCF-CPMs were testified for cytotoxicity against SKOV-3 ovarian cancer cell lines and peritoneal delivery advantages by animal experiments. The pharmacokinetics of LDCF-CPMs in rats following IP injection shows slow systemic absorption with mean residence time (MRT) of 13.54 h in comparison with 9.82 and 6.74 h for SE-CPMs and free CUR, respectively. In addition, IP delivery of CUR can expose the ovarian tumour to higher concentration for a longer duration by programming the thickness of the shell. The study provides compelling evidence for LDCF-CPMs having high therapeutic opportunity in the treatment of peritoneal cancers, such as ovarian, that reside in the peritoneal cavity.

Depression is a kind of mental illness accompanied by complex etiology and pathogenesis in clinic. With the quickening pace of circadian rhythm and increase of life pressure in modern society, the incidence of depression is increasing year by year. Nowadays, some typical antidepressant Western medicines, such as selective serotonin re-uptake inhibitors (SSRI) and tricyclic antidepressants (TCA), have been used as the main therapeutic drugs in clinic. Unfortunately, administration of these drugs will result in severe adverse reactions, slow treatments, and low cure rates, thus obviously they can not be used for a long term. Sini San, which originated from written by Zhang zhongjing, is a prescription widely applied in clinic for curing mental illness and also a basic Chinese herbal formula for modern treatment of depression. This article would review the research progress on antidepressant effects of Sini San based on single herbs of Bupleuri Radix and Paeoniae Radix Alba, herb-pair of Bupleuri Radix-Paeoniae Radix Alba, and formula of Sini San, providing directions and ideas for future research on complicated Chinese herbal formulae.

Pomegranate leaf (PGL) has a definite role in regulating lipid metabolism. However, pharmacokinetic results show the main active ingredient, ellagic acid, in PGL has lower oral bioavailability, suggesting that the lipid-lowering effect of PGL may act through inhibiting lipid absorption in the small intestine. Our results demonstrated that pomegranate leaf and its main active ingredients (i.e., ellagic acid, gallic acid, pyrogallic acid and tannic acid) were capable of inhibiting pancreatic lipase activity in vitro. In computational molecular docking, the four ingredients had good affinity for pancreatic lipase. Acute lipid overload experiments showed that a large dosage of PGL significantly reduced serum total cholesterol (TG) and triglycerides (TC) levels in addition to inhibiting intestinal lipase activity, which demonstrated that PGL could inhibit lipase activity and reduce the absorption of lipids. We also found that PGL could reverse the reduced tight-junction protein expression due to intestinal lipid overload, promote Occludin and Claudin4 expression in the small intestine, and enhance the intestinal mucosal barrier. In conclusion, we demonstrated that PGL can inhibit lipid absorption and reduce blood TG and TC by targeting pancreatic lipase, promoting tight-junction protein expression and thereby preventing intestinal mucosa damage from an overload of lipids in the intestine.

Heat stress can stimulate an increase in body temperature, which is correlated with increased expression of heat shock protein 70 (HSP70) and tumor necrosis factor α (TNFα). The exact mechanism underlying the HSP70 and TNFα induction is unclear. Berberine (BBR) can significantly inhibit the temperature rise caused by heat stress, but the mechanism responsible for the BBR effect on HSP70 and TNFα signaling has not been investigated. The aim of the present study was to explore the relationship between the expression of HSP70 and TNFα and the effects of BBR under heat conditions, using in vivo and in vitro models. The expression levels of HSP70 and TNFα were determined using RT-PCR and Western blotting analyses. The results showed that the levels of HSP70 and TNFα were up-regulated under heat conditions (40 °C). HSP70 acted as a chaperone to maintain TNFα homeostasis with rising the temperature, but knockdown of HSP70 could not down-regulate the level of TNFα. Furthermore, TNFα could not influence the expression of HSP70 under normal and heat conditions. BBR targeted both HSP70 and TNFα by suppressing their gene transcription, thereby decreasing body temperature under heat conditions. In conclusion, BBR has a potential to be developed as a therapeutic strategy for suppressing the thermal effects in hot environments.

Angelica dahurica (A. dahurica) is a traditional Chinese medicinal plant being used in clinical practice. The present study demonstrated that A. dahurica could reduce white-fat weight in high-fat-diet hyperlipidemic mice, decrease total cholesterol and triglyceride concentrations in the livers of both high-fat-diet and Triton WR1339 induced hyperlipidemic mice, and enhance the total hepatic lipase activities of them. These findings were further supported by the results derived from the experiments with HepG2 cells in vitro. In addition, the proteins related to lipids metabolism were investigated using LC-MS/MS, indicating that genes of lipid metabolism and lipid transport were regulated by A. dhurica. The results from LC-MS/MS were further conformed by Western blot and real time PCR assays. A. dahurica could down-regulate the expression of catalase (CAT) and sterol carrier protein2 (SCP2) and up-regulate the expression of lipid metabolism related genes-lipase member C (LIPC) and peroxisome proliferator-activated receptor gamma (PPARγ). In the Triton WR1339 mouse liver and HepG2 cells in vitro, A. dahurica was able to increase the expression of LIPC and PPARγ, confirming the results from in vivo experiments. Imperatorin showed the same activity as A. dahurica, suggesting it was one of the major active ingredients of the herb. In conclusion, our work represented a first investigation demonstrating that A. dahurica was able to regulate lipid metabolism and could be developed as a novel approach to fighting against fatty liver and obesity.

Brazilein is reported to have immunosuppressive effect on cardiovascular and cerebral-vascular diseases. The essential roles of innate immunity in cerebral ischemia are increasingly identified, but no studies concerning the influence of brazilein on the innate immunity receptors have been reported. The present study was designed to investigate the regulation of NOD2 (Nucleotide-binding oligomerization domain-containing protein 2) by brazilein for its protection of neuron in cerebral ischemia in vivo and oxygen-glucose deprivation in vitro. The results showed that brazilein could reverse the elevated expression of NOD2 and TNFα (tumor necrosis factor alpha) elicited by cerebral ischemia and reperfusion. This reduction could also be detected in normal mice and C17.2 cells, indicating that this suppressive effect of brazilein was correlated with NOD2. The results from GFP reporter plasmid assay suggested brazilein inhibited NOD2 gene transcription. In conclusion, brazilein could attenuate NOD2 and TNFα expression in cerebral ischemia and NOD2 may be one possible target of brazilein for its immune suppressive effect in neuro-inflammation.

Brazilein is an active small molecular compound extracted from Caesalpinia sappan L. with favorable pharmacological properties on immune system, cardiovascular system, and nervous system. C. sappan has been used as a traditional medicine in China for hundreds of years for various diseases. However, the general reproductive toxicity of brazilein is still unknown. The purpose of the present study was to thoroughly evaluate the general reproductive toxicity of brazilein in ICR mice to support the future drug development and modernization of this potent traditional Chinese medicine. The results showed that, although no apparent toxicity on the reproducibility of the male was observed, brazilein might cause considerable risks to the fetuses and females as indicated by the ratios of dead fetuses and reabsorptions. In conclusion, our results from the present study provided some useful insights about the safety profile of brazilein, suggesting that brazilein should be used with caution in pregnant women.

As the smallest unit of traditional Chinese medicinal formula compatibility, herb-pair has the basic characteristic of traditional Chinese medicinal formula compatibility. In recent years, herb-pair investigation has attracted much attention, which is an indispensable part of modernization of traditional Chinese medicine. With the decrease of the efficiency in the discovery of new drug, how to discover new drugs from traditional Chinese medicinal herb-pair has also been a bottleneck for the research and development of drug. The authors reviewed the domestic and foreign literatures in the latest years and summarized the current situations and the existing problems of herb-pair study. Based on these investigations, the authors innovatively proposed a novel concept of "precision herb-pair". Difference from traditional Chinese medicinal herb-pair or formulae with extensive roles and unclear efficacies, "precision herb-pair" belongs to a developed new mini herb-pair formula with an exact treatment and a relatively clear composition based on a certain specific disease. In addition, the authors also proposed a new strategy of "herb-pair - screen of multiple constituents based on column separation and in vitro cell viability - fuzzy target recognition pharmacology - re-evaluation of precision herb-pair", and successfully applied it to the development of a precision herb-pair from Astragali Radix-Corni Fructus in treatment of diabetic nephropathy. This proposed new strategy is simple, easy to carry out, and has a wide application, and can offer references and thoughts for the modern investigation of herb-pair and the research and development of new drug.

RESUMEN
The purpose of the present study is to confirm the protective effect of berberine (BBR) on gastrointestinal injury caused by acute heavy alcohol exposure, an effect that has not been reported previously. Our research details how BBR protects against gastrointestinal injuries from acute alcohol exposure using both in vivo and in vitro experiments. Acute high alcohol concentrations lead to obvious damage to the gastrointestinal mucosa, resulting in necrosis of the intestinal mucosa. Oral administration of BBR was able to significantly reduce this alcohol-induced damage, inhibit increases of alcohol-induced TNFα and IL-1ß expression in gastrointestinal mucosa as well as their upstream signals TLR2 and TLR4, and regulate cytokines that modulate tight junctions. Alcohol consumption is a popular human social behavior worldwide, and the present study reports a comprehensive mechanism by which BBR protects against gastrointestinal injuries from alcohol stress, providing people with a novel application of BBR.

Pineapple (Ananas comosus) leaves contain mainly phenolic components with antioxidant and hypolipidemic effects. One of the principle components is p-coumaric acid. In this study, the transport behavior of p-coumaric acid, was observed after the administration of pineapple leaf phenols in vitro. Simultaneously, the effect of the phenols on glucose, total cholesterol and triglycerides transportation and metabolism in HepG2 cells was also observed. The results showed that the phenols had good transport characteristics. 5 min after the administration, p-coumaric acid of the phenols could be detected, and the content of p-coumaric acid reached the peak concentration after 60 min of the administration. p-coumaric acid of phenols have time-and dose-dependent manner. While promoting glucose transporter (GLUT4) and low density lipoprotein receptor (LDLR) expression, the phenols decreased intracellular lipid content. This reduction of intracellular lipid content was highly correlated with the promotion of lipoprotein lipase (LPL) and hepatic triglyceride lipase (HTGL) expression, while the reduction of intracellular glucose levels was correlated with glycogen synthesis in the cells.

In this study, we aimed to investigate the effect and action mechanisms of pineapple leaf phenols (PLPs) on liver fat metabolism in high-fat diet-fed mice. Results show that PLP significantly reduced abdominal fat and liver lipid accumulation in high-fat diet-fed mice. The effects of PLP were comparable with those of FB. Furthermore, at the protein level, PLP upregulated the expression of carnitine palmitoyltransferase 1 (CPT-1), whereas FB had no effects on CPT-1 compared with the HFD controls. Regarding mRNA expression, PLP mainly promoted the expression of CPT-1, PGC1a, UCP-1, and AMPK in the mitochondria, whereas FB mostly enhanced the expression of Ech1, Acox1, Acaa1, and Ehhadh in peroxisomes. PLP seemed to enhance fat metabolism in the mitochondria, whereas FB mainly exerted the effect in peroxisomes. In addition, p-coumaric acid (CA), one of the main components from PLP, significantly inhibited fat accumulation in oleic acid-induced HepG2 cells. CA also significantly upregulated CPT-1 mRNA and protein expressions in HepG2 cells. We, firstly, found that PLP enhanced liver fat metabolism by upregulating CPT-1 expression in the mitochondria and might be promising in treatment of fatty liver diseases as alternative natural products. CA may be one of the active components of PLP.
RESUMEN
Rheum franzenbachii (called Tudahuang in local) has some similarities with R. palmatum (rhubarb) collected by "China Pharmacopoeia" and is often used as a substitute of rhubarb. Can Tudahuang simply replace rhubarb in the application or whether is there difference between Tudahuang and rhubarb, and what is the difference it is important to verify the difference and understand its proper application in the field of clinical practice. In this paper, we discussed the differences of the two herbs from the views of chemistry, efficacy and toxicity based on the author's previous research work as well as literatures, by using the major role of the rhubarb "diarrhea" as the basic point. The analysis result showed that the role of diarrhea Tudahuang was much weaker than that of rhubarb. The reason lies in the difference between the contents of combined anthraquinones component. While acute toxicity in mice of Tudahuang is stronger than that of rhubarb. Thus, Tudahuang should not simply replace rhubarb in practice.
