ABSTRACT
OBJECTIV E To develop the infor mation-based pharmaceutical care pathway of anticoagulant therapy in patients with atrial fibrillation and improve the efficacy and safety of treatment for them. METHODS The“anticoagulant pharmaceutical care”module was developed on the basis of medical intelligent and decision system. Patients with atrial fibrillation were taken pharmaceutical care in the whole anticoagulant treatment by evaluating the thromboembolism and bleeding risks ，pre-reviewing antithrombotic prescriptions ，monitoring efficacy and drug interactions ，and warning adverse reactions. RESULTS A total of 1 228 patients receiving anticoagulant therapy were enrolled. It was found after analysis of their doctor ’s orders that 9.27％ of the patients adjusted the improper antithrombotic therapies ，3.99％ modulated treatments according to the effects of potential drug interactions or the risk of adverse reactions ，and 70.29％ of the wrong prescriptions were intervened successfully. After the information-based pharmaceutical care ，the anticoagulation treatment rate increased from 88.73％ to 97.40％，the rate of patients ’achievements to warfarin’s international normalized ratio in hospital increased from 38.64％ to 66.67％，and the incidence of serious bleeding events decreased from 2.94％ to 0.37％ （P＜0.05）. CONCLUSIONS The information-based pharmaceutical care path of anticoagulant therapy achieved comprehensive ，efficient and accurate management of patients with atrial fibrillation ，and improved the rationality ，effectiveness and safety of anticoagulant therapy.
ABSTRACT
Ornithine decarboxylase (ODC) is a key enzyme in the biosynthetic pathway of polyamines and catalyzes the decarboxylation of ornithine to produce putrescine. Inhibition of ODC activity is a potential approach for the prevention and treatment of many diseases including cancer, as the expression levels and the activities of ODC in many abnormal cells and tumor cells are generally higher than those of normal cells. The discovery and evaluation of ODC inhibitors rely on the monitoring of the reaction processes catalyzed by ODC. There are several commonly used methods for analyzing the activity of ODC, such as measuring the yield of putrescine by high performance liquid chromatography, or quantifying the yield of isotope labelled carbon dioxide. However, the cumbersome operation and cost of these assays, as well as the difficulty to achieve high-throughput and real-time detection, hampered their applications. In this work, we optimized a real-time label-free method for analyzing the activity of ODC based on the macromolecule cucurbit[6]uril (CB6) and a fluorescent dye, DSMI (trans-4-[4-(dimethylamino) styryl]-1-methylpyridinium iodide). Finally, the optimized method was used to determine the activities of different ODC inhibitors with different inhibition mechanisms.

ABSTRACT
OBJECTIVE：To investigate the correlation between the morphological characteristics and chemical constituents of garden ginseng （GG），mountain transplanted ginseng （MTG）and mountain-grown ginseng （MGG），so as to provide evidence for elucidating the scientific connotation of “evaluating quality from morphological characteristics ”. METHODS ：A total of 30 batches of GG ，MTG and MGG were collected. The contents of 11 saponins（ginsenoside Rg 1，Re，Rg2，F1，Rb1，Rb2，Rb3，Rc，Rd，Ro， Rf）were determined by UPLC. The determination was performed on Acquity UPLC ® BEH C 18 column with mobile phase consisted of 0.1％ Formic acid solution- 0.1％ Acetonitrile formate solution （gradient elution ）at the flow rate of 0.5 mL/min. The column temperature was set at 35 ℃. The detection wavelength was set at 203 nm，and sample size was 5 μL. The content of starch was determined by colorimetry ，and the absorbance value was measured at 559 nm with 0.5％ iodine-potassium iodide as the color reagent. SPSS 23.0 statistical software was used to perform Pearson relationship analysis for appearance characteristic indexes （number of stem scars ，rhizome length ，texture）with the contents of 11 kinds of saponins ，the content of total saponins ，the content ratio of panaxatriol saponin （PPT）/panaxadiol saponin （PPD），the content of starch. RESULTS ：The linear relationship between UPLC and colorimetry was good （r＞0.999）. RSDs of precision ，reproducibility and stability tests were all lower than 5％ . Average recoveries were 95.17％ -105.20％（RSD＜5％ ，n＝6）. Except for ginsenoside Rf ，the contents of other 10 ginsenosides were positively correlated with the number of stem scars ，so were the contents of 11 gensenosides with the rhizome length（r＞0，P＜0.05），and they were negatively correlated with the firmness of the texture （r＜0，P＜0.05）. The content of starch in P. ginseng was positively correlated with texture firmness （r＝0.95，P＜0.01）. The ratio of PPT/PPD in P. ginseng was negatively associated with the number of stem scars and the rhizome length （r＜0，P＜0.05）. CONCLUSIONS ：The number of stem scars ，the rhizome length and texture porosity of P. ginseng are positively associated with the contents of medicinal material ginsenoside；the increase of PPD content in P. ginseng was higher than that of PPT with the increase of growth years. The traditional“evaluating quality from morphological characteristics ”for P. ginseng has a certain scientific connotation ，which is more stem scars ，longer rhizome and loose texture.

OBJECTIVE： To compare low-polarity volatile constituents in supercritical CO2 extract from the roots and stem of Ilex asprella and its effects on the proliferation of IEC-6 in vitro， and to provide reference for making full use of wild resources of I. asprella and expanding its medicinal parts. METHODS： The low-polarity volatile constituents were extracted from the root and stem of I. asprella with supercritical fluid CO2 extraction（SFE-CO2）. The chemical constituents were analyzed by GC-MS. IEC-6 cells were treated with different concentrations of supercritical CO2 extracts （0， 1， 5， 10， 20， 40， 60， 80， 100 μg/mL） from roots or stems of I. asprella. MTT assay was used to detect the relative viability， and cell proliferation curve was drawn and EC50 of each extract were calculated. RESULTS： Sixty-two and forty-six low-polarity volatile constituents were identified from supercritical CO2 extract in the roots and stem of I. asprella with GC-MS； there were 24 common constituents totally， mainly including pelargonic acid（14.18％ and 6.14％），octanoic acid（10.59％ and 4.35％），hexanoic acid（8.63％ and 10.86％），paeonol（7.79％ and 6.00％），2-methyl-3-phenyl-propanal（6.3％ and 0.58％），acetic acid（1.72％ and 33.77％） in root and stem， respectively. The results of cell culture in vitro showed that when the concentration of supercritical CO2 extract from the roots and stems of I. asprella was lower （≤60 μg/mL）， it could significantly promote the proliferation of IEC-6 cells and their EC50 were 16.35， 20.20 μg/mL， respectively； when the concentration of the extract was higher （≥80 μg/mL）， it showed cytotoxicity and inhibited the proliferation of IEC-6 cells. CONCLUSIONS： There are similar species of volatile constituents in roots and stems of I. asprella and similar in vitro bioactivity of the supercritical CO2 extracts to IEC-6 cells. The short-chain fatty acids may be the active ingredient to promote cell proliferation， while paeonol may be the cytotoxic active ingredient.

ABSTRACT
OBJECTIVE@#To explore the relationship between serum cystatin-C (Cys-c) levels and vibrating perception threshold (VPT) in patients with Type 2 diabetes mellitus (T2DM). @*METHODS@#According to the symptoms, signs and results of lab examination, a total of 352 patients with T2DM were divided into a diabetic peripheral neuropathy group (DPN group, n=107) and a non-diabetic peripheral neuropathy group (NDPN group, n=245). Serum Cys-c levels were measured by radioimmunoassay method. The relationship between serum Cys-c levels and VPT, estimated glomerular filtration rate (eGFR), urinary albumin-to-creatinine ratio (ACR), glucose and blood pressure and other parameters were also analyzed by correlation and multiple regression analysis. All T2DM patients were divided into a high Cys-c levels group (n=89) and a low Cys-c levels group (n=263) according to the upper quartile of Cys-c, and the incidence of DPN and VPT levels in each group were compared. Risk factors of DPN in T2DM patients were analyzed by binary logistic regression analysis and receiver operating characteristic (ROC) curve was used to identify the optimal cutoff of serum Cys-c levels for predicting DPN in patients with T2DM. @*RESULTS@#Serum Cys-c levels were significantly higher in the DPN group than that in the NDPN group [(1.04±0.43) vs (0.80±0.25) mg/L, P0.996 mg/L, the predicts have high risk of DPN in T2DM patients, which might be related to diabetic nephropathy, oxidative stress and inflammatory reaction induced by advanced age, hyperglycemia and hypertension.

Objective To investigate the effects of ketogenic amino acid ( KAA) replacement diet on insulin resistance in mice fed with high fat diet(HFD) and to analyze the possible mechanism. Methods C57BL mice were fed with a control diet, HFD, and KAA-fortified HFD(HFDKAAR)from the age of 8 weeks, and 8 weeks after HFD initiation, the HFD-fed mice were divided into two groups:one group of mice were fed the same HFD, the other group were fed HFDKAAR ( HFD→HFDKAAR ) . The metabolic evaluations were performed at the end of 16 weeks. Blood glucose levels were measured at 0, 15, 30, 60, 90, and 120 min after the injection of glucose ( 1 g/kg BW intraperitoneal glucose tolerance test, ipGTT) . The insulin,β-hydroxybutyrate, and acetoacetate levels in the plasma were measured via ELISA. The insulin resistance index ( IRI) and area under curve ( AUC) were calculated. The expression of hepatic LKB1 ( liver kinase B1 ) , AMP-activated protein kinase ( AMPK ) , and mTOR ( Mammalian target of rapamycin ) protein, and mcp-1 mRNA were measured by western blot and real-time PCR respectively. Results HFD-fed group of mice displayed significantly heavier body weight,heavier intra-abdominal fat weight, and significant deterioration of glucose tolerance at the end of 16 weeks in addition to higher insulin levels( all P<0. 05), HFDKAAR-fed mice exhibited significantly ameliorated high fat diet-induced obesity and glucose intolerance compared to the HFD-fed mice, which was associated with decreased insulin levels, IRI, AUC, and mcp-1 mRNA expression (all P<0. 05). HFD suppressed hepatic LKB1 and AMPK phosphorylation expression, and increased mTOR phosphorylation levels compared to the control diet-fed mice(all P<0. 05). In contrast, treatment with the HFDKAAR diet increased LKB1and p-AMPK expression, which was associated with suppressed p-mTOR levels compared to the HFD-fed mice(all P<0. 05). Conclusion KAA may ameliorate high fat diet-induced obesity, glucose intolerance, via normalizing the hepatic LKB1-AMPK-mTOR nutritional signal passageway. KAA replacement diet seems to be a potential nutritional intervention for the treatment for patients with metabolic defects, such as obesity, glucose intolerance, as well as metabolic syndrome.
