Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Hehuan Yin decoction (HHY), first recorded in the Jingyue Quanshu (published in 1624 A.D.), is composed of Albizia julibrissin Durazz. and Ampelopsis japonica (Thunb.) Makino. AIM OF THE STUDY This study aimed to investigate the mechanism of action of HHY in treating polycystic ovary syndrome with insulin resistance (PCOS-IR). MATERIALS AND METHODS Network pharmacology and molecular docking were used to predict active compounds, potential targets, and pathways for PCOS-IR treatment using HHY. Female Sprague-Dawley rats were administered letrozole (1 mg/kg) with a high-fat diet to establish a PCOS-IR model. Thereafter, symptoms, ovarian pathology, serum insulin resistance, and sex hormone levels were determined. Western blotting was used to determine the levels of PI3Kp85α, AKT, phospho (p)-AKT, and GSK3β in the ovaries of rats. RESULTS Network pharmacology revealed 58 components in HHY and 182 potential targets that were shared between HHY and PCOS-IR. HHY could potentially treat PCOS-IR via the insulin resistance, PI3K/AKT, HIF-1, and steroid hormone biosynthesis pathways. Molecular docking revealed that PI3K, AKT1, GSK3β, IRS1, and EGFR had high affinities to HHY compounds. In the PCOS-IR rats, HHY significantly normalised the symptoms and ovarian pathology, increased follicle-stimulating hormone (FSH) and oestradiol levels in the serum, and decreased the levels of fasting plasma glucose and fasting insulin, as well as the insulin resistance index. HHY also decreased the luteinising hormone (LH) and testosterone levels and the LH/FSH ratio in the PCOS-IR rats and increased the levels of PI3K, p-AKT, and GSK3β in ovary tissue, which indicated the activation of the PI3K/AKT pathway. CONCLUSIONS HHY can improve PCOS-IR symptoms via multiple pharmacological pathways and may be a potential alternative therapy for the treatment of PCOS-IR.

Abstract
Phellodendri Chinensis Cortex (PCC) and Atractylodis Rhizoma (AR) are frequently used as herb pair to treat eczema and gout owing to their synergistic effects. Alkaloids are the major ingredients from PCC and the effect of their combination on the in vivo processing of alkaloids remains unclear. In this study, a simple and reliable UPLC-MS/MS method for simultaneous determination of six alkaloids in rat plasma was developed. This method was applied to a comparative pharmacokinetic study between PCC and PCC-AR in rats. Effect of AR on absorption of alkaloids was investigated by a single-pass intestinal perfusion study. The effect of AR on urinary excretion of alkaloids was studied. Pharmacokinetic studies showed that the values of rea under the concentration-time curve of phellodendrine, magnoflorine and palmatine were greater in the PCC-AR group than in the PCC group. The intestinal absorptive parameters absorption rate constant and effective permeability of phellodendrine and jatrorrhizine in PCC-AR groups were higher than those in the PCC group. Urinary excretion studies revealed that the excreted amount of alkaloids in the PCC-AR group was lower than that in the PCC group. The results revealed that the combination of PCC and AR improves intestinal absorption of alkaloids and reduces their urinary excretion, which enhances their systemic exposure. This study may explain the synergetic effects of PCC and AR in clinical applications.

Abstract
BACKGROUND Ulcerative colitis (UC) is a chronic inflammatory bowel disease with high morbidity, which leads to poor quality of life. The Xianglian pill (XLP) is a classical Chinese patent medicine and has been clinically proven to be an effective treatment for UC. PURPOSE The pharmacological mechanism of the key bioactive ingredients of XLP for the treatment of UC was investigated by a network pharmacology and pharmacokinetics integrated strategy. STUDY DESIGN AND METHODS Network pharmacology was used to analyze the treatment effect of nine quantified XLP ingredients on UC. Key pathways were enriched and analyzed by protein-protein interaction and Kyoto Encyclopedia of Genes and Genomes analyses. The effect of XLP on Th17 cell differentiation was validated using a mouse model of UC. The binding of nine compounds with JAk2, STAT3, HIF-1α, and HSP90AB1 was assessed using molecular docking. A simple and reliable ultra-high-performance liquid chromatography-tandem mass spectrometry method was developed for the simultaneous quantification of nine ingredients from XLP in plasma and applied to a pharmacokinetic study following oral administration. RESULTS Nine compounds of XLP, including coptisine, berberine, magnoflorine,berberrubine, jatrorrhizine, palmatine, evodiamine, rutaecarpine, and dehydrocostus lactone, were detected. Network pharmacology revealed 50 crossover genes between the nine compoundsand UC. XLP treats UC mainly by regulating key pathways of the immune system, including Th17 cell differentiation, Jak-Stat, and PI3K-Akt signaling pathways. An in vivo validation in mice found that XLP inhibits Th17 cell differentiation by suppressing the Jak2-Stat3 pathway, which alleviates mucosal inflammation in UC. Molecular docking confirmed that eight compounds are capable of binding with JAk2, HIF-1α, and HSP90AB1, further confirming the inhibitory effect of XLP on the Jak2-Stat3 pathway. Moreover, apharmacokinetic study revealed that the nine ingredients of XLP are exposed in the plasma and colon tissue, which demonstrates its pharmacological effect on UC. CONCLUSION This study evaluates the clinical treatment efficacy of XLP for UC. The network pharmacology and pharmacokinetics integrated strategy evaluation paradigm is efficient in discovering the key pharmacological mechanism of herbal formulae.

Abstract
Purpose Ferulic acid (FA) is a natural compound which is used to treat insomnia. However, its use is limited because of its poor oral bioavailability caused by extremely rapid elimination. The current study aimed to develop a self-microemulsifying drug delivery system (SMEDDS) to improve the oral delivery of FA and to enhance its hypnotic efficacy. Methods FA-SMEDDS was prepared, and its morphology and storage stability were characterized. The formulation was also subjected to pharmacokinetic and tissue distribution studies in rats. The hypnotic efficacy of FA-SMEDDS was evaluated in p-chlorophenylalanine-induced insomnia mice. Results FA-loaded SMEDDS exhibited a small droplet size (15.24 nm) and good stability. Oral administration of FA-SMEDDS yielded relative bioavailability of 185.96%. In the kidney, SMEDDS decreased the distribution percentage of FA from 76.1% to 59.4% and significantly reduced its metabolic conversion, indicating a reduction in renal elimination. Interestingly, FA-SMEDDS showed a higher distribution in the brain and enhanced serotonin levels in the brain, which extended the sleep time by 2-fold in insomnia mice. Conclusion This is the first study to show that FA-loaded SMEDDS decreased renal elimination, enhanced oral bioavailability, increased brain distribution, and improved hypnotic efficacy. Thus, we have demonstrated that SMEDDS is a promising carrier which can be employed to improve the oral delivery of FA and facilitate product development for the therapy of insomnia.

Abstract
Objective: To observe the effect of tumor necrosis factor-α (TNF-α) monoclonal antibody on autophagy in allergic rhinitis (AR) mice. Methods: Thirty six weeks old BALB/c mice were randomly divided by random number table method into five groups: control group, model group (AR group), TNF-α antibody intervention group (AR+TNF-α group), autophagy inhibitor (3-methylindole, 3-NA) intervention group (AR+3-MA group), TNF-α antibody combined with autophagy inducer rapamycin (RAP) intervention group (AR+TNF-α+RAP group), with 6 mice in each group. AR model was established by conventional method, the corresponding reagent was administered before nasal cavity stimulation sensitization and during the whole experiment. Behavioral scores of mice were obtained, blood was collected from the eye socket, and mice in each group were sacrificed to collect nasal mucosa tissue samples. Pathological changes of nasal mucosa were observed by hematoxylin-eosin staining. Expression levels of inflammatory factor and IgE in serum were detected by enzyme-linked immunosorbent assay (ELISA). Expressions of autophagy related indicators microtubule-associated protein-1 light chain-3B (LC3B), Beclin-1, sequestosome1 (p62), autophagy-related 5 (ATG5), autophagy-related 7 (ATG7) were measured by Real-time PCR and Western blot. The aggregation of LC3B protein was observed by immunofluorescence. SPSS 19.0 software was used for statistical analysis. Results: Compared with the AR model group, symptoms of AR in AR+TNF-α group and AR+3-MA group were mild; the pathological changes of nasal mucosa were weak; the expression of IgE, TNF-α, interleukin 4 (IL-4), interferon-γ (IFN-γ) in serum significantly reduced (IgE: 666.19±78.35 (x±s) vs. 692.38±64.29 vs. 1 059.05±146.44, TNF-α: 112.06±12.95 vs. 113.17±15.43 vs. 161.22±17.96, IL-4: 54.05±7.14 vs. 58.26±5.67 vs. 79.95±6.33, IFN-γ: 28.58±4.51 vs. 30.67±2.60 vs. 39.83±3.31, all P<0.05), and the expression of LC3B Ⅱ/Ⅰ, Beclin-1, ATG5, ATG7 in nasal mucosa significantly decreased, the expression of p62 significantly elevated. After intervention with autophagy inducer RAP, the therapeutic effect of TNF-α monoclonal antibodies on AR was antagonized. Conclusion: TNF-α monoclonal antibody significantly improves nasal symptoms in AR mice by inhibiting autophagy levels.

Abstract
Gut microbiota and its metabolites, short-chain fatty acids (SCFAs), play important roles in diarrheal diseases. Gegen Qinlian decoction (GQD), a Chinese herb formula, has been widely used to treat infectious diarrhea for centuries. However, little is known about the mechanism underlying its efficacy and whether it is mediated by gut microbiota and SCFAs. In this study, the composition of gut microbiota from bacterial diarrheal piglets was assessed using 16S rRNA analysis. The concentrations of fecal SCFAs were determined using a gas chromatography-mass spectrometer (GC-MS). The expression of mucosal pro-inflammatory cytokines in the colon was ascertained. Results showed that GQD reverses the reduction in the richness of gut microbiota, changes its structure, and significantly increases the relative abundances of SCFA-producing bacteria, including Akkermansia, Bacteroides, Clostridium, Ruminococcus, and Phascolarctobacterium. Moreover, GQD increased the levels of fecal SCFAs, including acetic acid, propionic acid, and butyric acid. GQD thus attenuates diarrhea in piglets. Further, our results suggest that the SCFAs could help to attenuate mucosal pro-inflammatory responses following GQD treatment by inhibiting histone deacetylase and the NF-κB pathway. We thus suggseted that gut microbiota play an important role during diarrhea treatment, an effect may be promoted by the GQD-induced structural changes of the gut microbial community and production of SCFAs. The increased levels of SCFAs probably provide further help to attenuate mucosal inflammation and diarrhea. In conclusion, our study might provide evidence that GQD treats diarrhea maybe involved in modulating gut microbiota and increasing SCFA levels.

Abstract
Puerariae Radix (PR) and Gastrodiae Rhizome (GR) is frequently used in traditional herbal formulas to treat cardio-cerebral vascular diseases due to their synergistic effects. In this study, to elucidate the action mechanism of PR-GR in vivo, a simple and reliable ultra-performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS) method for simultaneous determination of nine bioactive ingredients from PR-GR in plasma was developed and applied to a comparative pharmacokinetic study following oral administration of PR, GR, and PR-GR aqueous extracts in rats. The effect of GR on the absorption of components of PR was also investigated by single-pass intestinal perfusion study. Results showed that comparing to the single herbs, PR-GR extract significantly increased the systemic exposure of puerarin, 3'-hydroxypuerarin, 3'-methoxypuerarin, 6″-O-xylosylpuerarin, daidzin, genistein, and gastrodin. Moreover, the intestinal absorption of puerarin and daidzin could be improved by GR extract and inhibitors of P-glycoprotein and multidrug resistanceassociated protein 2, respectively. These results indicate that the combination of PR and GR increases the levels of their bioactive ingredients exposed in the blood, and GR increases the absorption of ingredients of PR may by inhibition of the efflux mediated by P-glycoprotein and multidrug resistanceassociated protein 2. This is the first report for the pharmacokinetics and intestinal absorption of PR-GR, which may explain their synergetic effects in the treatment of circulatory systematic diseases and provide a meaningful insight for their clinical applications.

Abstract
Diarrhoeal diseases alter the composition of intestinal flora, thereby affecting the efficacy of herbal medicinal formulations. Gegen Qinlian decoction (GQD), a Chinese traditional herbal formulation, is widely used to treat infectious diarrhoea. However, little is known about the microbial disposition of GQD in the diarrhoeal state. In this study, the comparative metabolism of components of GQD by diarrhoeal and normal intestinal flora was investigated in vitro. UPLC-MS/MS was performed for simultaneous analysis of eight ingredients of GQD in bacterial solution. The type, activities, and sources of microbial enzymes were also investigated. Microbial metabolism of daidzin, genistin and liquiritin (metabolized by β-glucosidase); baicalin, wogonoside and glycyrrhizin (metabolized by β-glucuronidase); and berberine and coptisine (metabolized via nitroreductase) was faster in the diarrhoeal group than in the normal group. Moreover, the activities of these enzymes in the diarrhoeal group were higher than those in the normal group. This difference might be associated with the increase in Escherichia spp. Thus, a change in the metabolism of components by diarrhoeal intestinal flora is associated with a preponderance of Escherichia spp., which might improve the efficacy of GQD. These findings have implications for understanding the action mechanism of GQD for diarrhoea treatment in terms of the microbial milieu.

Abstract
OBJECTIVE To investigate the pharmacokinetic characteristics of three phenylpropanoids (cinnamic acid, cinnamic alcohol and coumarin) in Ramulus Cinnamomi (GZ) and Ramulus Cinnamomi-Ephedrae Herba (MH) herb-couple (GZMH). METHODS Twelve male Sprague-Dawley rats were randomly and equally divided into the GZ and GZMH herb-couple groups. Blood samples were collected at 0, 0.08, 0.25, 0.5, 0.75, 1.5, 3, 4, 6, 8, 12, 24, 36 and 48 h after oral administration. The three phenylpropanoids in rat plasma were quantified using an ultra-performance liquid-chromatography with tandem mass spectrometry (UPLC-MS/MS) method for pharmacokinetic study. RESULTS In GZMH group, the area under the curve (AUC), mean retention time (MRT) of cinnamic acid and coumarin were increased significantly (P<0.01, respectively), and biological half-life (t1/2z) was obviously shorter (P<0.05) compared with the GZ group. There were no significant differences in the mean retention time from 0 to ∞ (MRT0-∞), the peak concentration (Cmax), the time to peak (Tmax) and t1/2z, except for AUC and MRT0-t (the mean retention time from 0 to t) of cinnamic alcohol in the GZMH group by comparison to the GZ group (P<0.01, respectively). The AUC, MRT (both P<0.01) and t1/2z (P<0.05) of coumarin were increased significantly, while Cmax, and Tmax were decreased slightly by comparison to the GZ group (P>0.05). CONCLUSIONS There were statistically significant differences in some pharmacokinetic parameters of the three compounds between GZ and GZMH groups, which meant that MH could affect the absorption and elimination of the three compounds.

Abstract
OBJECTIVE Mahuang-Shigao herb-pair is a famous formula composed of Ephedra and Gypsum. The herb-pair is frequently used for treating cold symptoms and bronchial asthma in the clinical practice of Chinese medicine (CM). In the present study, we evaluated evidence for the benefit of combined use of Ephedra and Gypsum by analyzing the antipyretic and anti-asthmatic activities of Ephedra-Gypsum. METHODS The antipyretic effects of Ephedra-Gypsum were evaluated in yeast-induced hyperthermia test. Thirty male Wistar rats were randomly divided into 5 groups, including control group, standard aspirin group, and 3 Ephedra- Gypsum groups of different doses (6, 12, 24 g/kg). Ephedra-Gypsum extract and asprin were administered orally 6 h after the injection of yeast solution and body temperature was measured every 1 h for 8 h. The antiasthmatic effects of Ephedra-Gypsum were evaluated using an ovalbumin (OVA)-induced asthmatic rat model. Thirty-six male SD rats were randomly divided into 6 groups. Rats were alternately sensitized and OVA+Al(OH) challenged by exposure to mists of ovalbumin. Ephedra-Gypsum extracts (6, 12, 24 g/kg) or dexamethasone were administered 45 min prior to the allergen challenge for 8 days. Latent period and the weight of wet to dry ratio of lung were determined. In addition, the eosinophils in blood and white blood cell (WBC) were counted by an YZ-Hemavet Analyzer. RESULTS The Ephedra-Gypsum extracts at test dose (6, 12, 24 g/kg) significantly and dose-dependently attenuated yeast-induced fever in rats. The Ephedra-Gypsum extracts also prolonged the latent period, reduced OVA-induced increases in eosinophils and WBC, and decreased the wet and dry weight ratio of the lungs in the anti-asthmatic test. CONCLUSIONS These findings indicate that the Ephedra-Gypsum extract has antipyretic and anti-asthmatic properties. Hence, the results support additional scientific evidence in prescriptions.

Abstract
Dexamethasone has been widely used before general anesthesia induction. However, previous studies have found that a pre-induction bolus dose of dexamethasone sometimes causes perineal pruritus. We hypothesized that an appropriate prolongation of the injection time might suppress dexamethasone-induced perineal pruritus. Four hundred patients requiring general anaesthesia were randomly allocated into four groups: group I receiving 2 ml dexamethasone (5 mg/ml); group II receiving 4 ml dexamethasone (2.5mg/ml); group III receiving 10 ml dexamethasone (1 mg/ml); and group IV receiving 20 ml dexamethasone (0.5 mg/ml). Dexamethasone was diluted with 0.9% sodium chloride. The injection time of dexamethasone was 5s in groups I, II and III; while the injection time of dexamethasone was 30s in group IV. Occurrence of perineal pruritus was significantly reduced in Group IV (0% vs 38%, 32% and 12% in Groups I, II and III, respectively, p < 0.05). The incidence was higher in females than in males (p < 0.05). The duration of perineal pruritus was longer in females than in males in groups I, II and III (p < 0.05). We conclude that the dilution of dexamethasone to 0.5 mg/ml with 0.9% sodium chloride combined with prolonged injection time to 30 s eliminates dexamethasone-induced perineal pruritus.

Abstract
The first monoterpene-based meroterpenoid (1) and two novel sesquiterpene-based ones (2 and 3) with unprecedented skeletons were isolated from the leaves of Psidium guajava. Their structures with absolute configuration were elucidated by extensive spectroscopic studies. A plausible biosynthetic pathway for all meroterpenoids from the title plant is also proposed. Compounds 2 and 3 showed significant cytotoxicity toward HepG2 and HepG2/ADM cells.

Abstract
This prospective, randomized, controlled study evaluated plasma levels of interleukin-18 (IL-18) and monocyte chemotactic protein-1 (MCP-l) in patients undergoing cholecystectomy. Forty patients were randomized to undergo laparoscopic cholecystectomy (LC) or open cholecystectomy (OC). Plasma concentrations of IL-18 and MCP-1 were measured before anaesthesia (T(0)), before operation (T(1)), 30 min after the start of the operation (T(2)) and at the end of the operation (T(3)). Compared with T(0), the IL-18 concentration was significantly increased at T(2) and T(3) in both groups. In addition, the MCP-1 concentration was significantly increased at T(3) compared with T(0) in the LC group. Both the IL-18 and MCP-1 concentrations were significantly lower in the OC group than in the LC group at T(3). It is suggested that carbon dioxide pneumoperitoneum may cause immunodepression, that epidural anaesthesia can attenuate the stress response, and that IL-18 and MCP-1 are sensitive markers for evaluating the patient's immune function.

Abstract
This prospective, randomized controlled study evaluated the effects of acute hypervolaemic haemodilution (AHH) on the expression of plasma interferon-inducible protein-10 (IP-10) and bactericidal/permeability-increasing protein (BPI) in patients undergoing elective total hip replacement. Twenty patients were randomized to receive an infusion of either hydroxyethyl starch (HES group) or lactated Ringer's solution (LR group) immediately after anaesthesia. Plasma concentrations of IP-10 and BPI were measured before anaesthesia (baseline), at the start of surgery, 30 min after the start of surgery and at the end of surgery. Blood loss and the volume of blood transfused were significantly lower in the HES group compared with the LR group. Compared with baseline, IP-10 and BPI concentrations increased significantly in both groups 30 min after the start of surgery. The IP-10 concentrations were significantly lower and BPI concentrations significantly higher in the HES group compared with the LR group 30 min after the start of surgery and at the end of surgery. It is concluded that AHH with HES may be helpful in ameliorating immune function during total hip replacement and in reducing blood loss and the extent of blood transfusion.

Abstract
BACKGROUND Analgesics are commonly used to provide pain relief after surgery. These drugs produce some extended depression of immunity. A prospective randomized controlled trial was designed to observe expressions of T-lymphocyte subsets (CD3(+), CD3(+)CD4(+) and CD3(+)CD8(+)), natural-killer cells (CD3(-)CD16(+)CD56(+)), and activated T-lymphocytes (CD3(+)CD25(+)) of patients undergoing gastric cancer surgeries and receiving patient-controlled intravenous analgesia (PCIA). METHODS Forty-five patients undergoing elective gastric cancer surgeries under general anesthesia were randomly allocated into 3 groups. Group I received PCIA using morphine after surgery, group II using tramadol, and group III using tramadol with lornoxicam. The analgesic efficacy was evaluated by visual analog scale (VAS) and Bruggrmann comfort scale (BCS). Expressions of CD3(+), CD3(+)CD4(+), CD3(+)CD8(+), CD3(-)CD16(+)CD56(+), and CD3(+)CD25(+) were measured as percentages of total lymphocytes by flow cytometer at 5 time points. RESULTS There was no significant difference in analgesic efficacy and the baselines of CD3(+), CD3(+)CD4(+), CD3(+)CD8(+), CD3(-)CD16(+)CD56(+), and CD3(+)CD25(+) in all groups. Compared with the baseline, CD3(+)CD8(+) had no changes in all groups at any time point. Ninety minutes after incision, CD3(+), CD3(+)CD4(+), CD3(-)CD16(+)CD56(+), and CD3(+)CD25(+) were lower in all groups (P<0.05). 24 h after surgery, CD3(+), CD3(+)CD4(+), CD3(-)CD16(+)CD56(+), and CD3(+)CD25(+) were lower in group I and group II (P<0.05); meanwhile CD3(+), CD3(+)CD4(+), and CD3(+)CD25(+) returned to the baseline but CD3(-)CD16(+)CD56(+) was still low (P<0.05) in group III. 48 h after surgery, CD3(+), CD3(+)CD4(+), CD3(-)CD16(+)CD56(+), and CD3(+)CD25(+) returned to the baseline in group II and group III, but not in group I (P<0.05). 72 h after surgery, CD3(+), CD3(+)CD4(+), CD3(+)CD4(+)/CD3(+)CD8(+) returned to the baseline, but CD3(+)CD25(+) and CD3(-)CD16(+)CD56(+) were still low in group I (P<0.05). CONCLUSION PCIA using lornoxicam with tramadol has the same good analgesic efficacy and less immunity depression than PCIA using morphine or tramadol.
