To compare the chemical change of Paeoniae Radix Alba (PRA) after vinegar-baking processing, as well as the effect of vinegar types exerted on the processing, 1H NMR-based metabolomic approach combined with multivariate statistical analysis was used to investigate the different metabolites between the raw and two vinegar-baked PRA. More than thirty metabolites were identified in the 1H NMR spectrum of PRA, and the multivariate statistical analysis showed that raw and two vinegar-baked PRA could be separated obviously. After vinegar-baking, the contents of isoleucine, lactate, alanine, arginine, albiflorin, and 5-hydroxymethyl furfural (5-HMF) elevated, while those of sucrose, paeoniflorin and its analogues (calculated by benzoate) decreased. The chemical compositions of two vinegar-baked PRA were also different. Shanxi vinegar- baked PRA showed higher levels of leucine, isoleucine, valine, and albiflorin, while rice vinegar-baked PRA contained more sucrose and paeoniflorin's analogues (calculated by benzoate). And the chemical changes in Shanxi vinegar-baked PRA were greater than those of rice vinegar-baked PRA. The results revealed the chemical differences between raw and vinegar-baked PRA, as well as the influence of vinegar type on processing, in a holistic manner, the results obtained suggested that the correlations between the chemical change and the drug action after processing, as well as the vinegar type used in processing, should be further studied.

Objective To explore the efficacy and safety of low-dose ketamine for prevention of shivering during cesarean section under subarachnoid space and epidural anesthesia.Methods Ninety pregnant women who scheduled cesarean delivery under subarachnoid space and epidural anesthesia were randomized divided into three groups:control group (30 patients) low-dose ketamine group (30 patients) and high-dose ketamine group (30 patients).0.9％ sodium chloride,0.25 mg/kg(3 ml),and 0.50 mg/kg (3 ml) ketamine were given in three groups before operation.The incidence of shivering and adverse effect were recorded respectively before anesthesia,after anesthesia 15 min and 30 min and after operation 1 h.Results The level of mean arterial pressure (MAP) in control group after anesthesia 15 main and 30 min and after operation 1 h[(62 ± 10),(58 ± 8),(61 ± 11) mm Hg(1 mm Hg =0.133 kPa)] were significantly lower than those in high-dose ketamine group [(78 ± 12),(82 ± 8),(76 ± 11)mm Hg] and low-dose ketamine group [(72 ± 10),(76 ± 6),(80 ± 7) mm Hg],there was significant difference (P ＜ 0.05).There was no shivering need treat in low-dose ketamine group and high-dose ketamine group.The rate of hallucinations and nystagmus in low-dose ketamine group [0,6.7％ (2/30)] was significantly lower than that in high-dose ketamine group [20.0％ (6/30),50.0％ (15/30)],there was significant difference (P ＜ 0.05).Conclusion The pretreatment with low-dose ketamine on shivering during cesarean section under subarachnoid space and epidural anesthesia has better preventive effectiveness,0.25 mg/kg of ketamine is more effective than 0.50mg/kg.

BACKGROUND: Research has been reported that serum soluble CD146 (sCD146) expression was improved on the surface of endothelial cells and activated T cells by the stimulation of inflammatory factor. Therefore, it predicts that CD146 may participate in inflammatory reaction of tissue.OBJECTIVE: To investigate the expression and clinical significance of serum sCD146 in peripheral blood from patients with ankylosing spondylitis.METHODS: A total of 62 patients with ankylosing spondylitis were selected from the Sixth People's Hospital AffiUated to Shanghai Jiao Tong University. All patients were divided into two groups: active group (n=46) and inactive group (n=16); while, 20 healthy subjects were selected as the control group. Indicators including Bath Ankylosing SpondyUtis Disease ActivityIndex (BASDAI),Bath Ankylosing Spondylitis Functional Index (BASFI), patient's global assessment (PGA), night pain, visual analogue scale (VAS),morning stiffness time, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) were measured in all patients. The serum concentration of sCD146 from 62 patients with ankylosing spondlitis and 20 healthy controls was measured by enzyme-linked immunosorbent assay. Westergren method was used to measure ESR and immunoturbidimetry for CRP. Clinical data of the patients were collected as well.RESULTS AND CONCLUSION: sCD146 levels of patients with ankylosing spondlitis were significantly higher than normal control group (P ＜ 0.05). The sCD146 expression in the active group was significantly higher than inactive and normal control groups (P ＜0.05). Positive correlations were observed between sCD146 and BASDAI index of patients with ankylosing spondlitis (P ＜ 0.05).The sCD146 levels of ankylosing spondUtis patients with peripheral joint involvement were significantly higher than the patients with axial involvement alone or the normal controls (P ＜ 0.05).The expression level of sCD146 in peripheral blood was positively correlated with disease activities of patients with ankylosing spondlitis. It may play important roles in the pathogenesis in ankylosing spondlitis.

Objective:To synthesize the mental resilience of Chinese children tested with the Resilience Scale for Chinese Adolescents (RSCA)to evaluate its status as well as the research status. Methods:Four Chinese elec-tronic databases including China Biology Medicine disc (CBM),VIP Database,China National Knowledge Infra-structure (CNKI)and WangFang Database were searched from database established to December 2014. Literatures that reported the mental resilience status of Chinese children tested with RSCA were included. A statistical formula was used to synthesize means and standard deviations to get a total score;the standard mean difference (SMD)and 95% confidence interval (95%CI)of scores measured with RSCA scale were used to conduct meta-analyses usingthe software of Review Manager 5. 2 for comparison between different subgroups. Results:Thirty-nine studies with 16 493 children were included for the final analysis. Quantitative synthesis results showed that the average total score of Chinese children was (3. 3 0. 6 ). The status of psychological resilience was at a good level. The average psychological resilience scores of girls,not left-behind children,urban children,Han children and not-only-child were higher than those of boys [SMD (95%CI):-0. 09 (-0. 14--0. 05 )],left-behind children [SMD (95%CI):-0. 37(-0. 56--0. 19)],rural children [SMD (95%CI):0. 26(0. 13 -0. 38)],minority children [SMD (95%CI):0. 12(0. 04-0. 21)]and only-children [SMD (95%CI):0. 30(0. 16-0. 44)]respectively. Conclusion:The mental resilience of Chinese children is modest with internal diversity.

Water soluble extract (WSE) is an important index for the quality evaluation of Astragali Radix (AR). In this study, the WSE of the wild AR from Shanxi province (SX) and the cultivated AR from Gansu Province (GS) were compared. The WSEs of two types of AR were determined according to the appendix of Chinese pharmacopoeia. Then the WSEs were subjected to NMR analysis, and the obtained data were analyzed using HCA, PCA, OPLS-DA, microarray analysis, and Spearman rank analysis. In addition, the Pearson correlation of differential metabolites were also calculated. The results showed that the WSE content of GS-AR (37.80%) was higher than that of SX-AR (32.13%). The main constituent of WSE was sucrose, and other 18 compounds, including amino acids, organic acids, were also detected. Multivariate analysis revealed that SX-AR contained more choline, succinic acid, citric acid, glutamate, taurine and aspartate, while GS samples contained more sucrose, arginine and fumaric acid. In addition, the Pearson correlations between different metabolites of the two types of AR also showed apparent differences. The results suggested that the WSE of two types of AR differs not only in the content, but also in the chemical compositions. Thus, the cultivation way is important to the quality of AR. This study supplied a new method for the comparison of extract of herbal drugs.

Chronic myeloid leukemia (CML) is characterized by the accumulation of active BCR-ABL protein.Imatinib is the first-line treatment of CML;however,many patients are resistant to this drug.In this study,we aimed to compare the differences in expression patterns and functions of time-series genes in imatinib-resistant CML cells under different drug treatments.GSE24946 was downloaded from the GEO database,which included 17 samples of K562-r cells with (n=12) or without drug administration (n=5).Three drug treatment groups were considered for this study:arsenic trioxide (ATO),AMN107,and ATO+AMN107.Each group had one sample at each time point (3,12,24,and 48 h).Time-series genes with a ratio of standard deviation/average (coefficient of variation) ＞0.15 were screened,and their expression patterns were revealed based on Short Time-series Expression Miner (STEM).Then,the functional enrichment analysis of time-series genes in each group was performed using DAVID,and the genes enriched in the top ten functional categories were extracted to detect their expression patterns.Different time-series genes were identified in the three groups,and most of them were enriched in the ribosome and oxidative phosphorylation pathways.Time-series genes in the three treatment groups had different expression patterns and functions.Time-series genes in the ATO group (e.g.CCNA2 and DAB2)were significantly associated with cell adhesion,those in the AMN107 group were related to cellular carbohydrate metabolic process,while those in the ATO+AMN107 group (e.g.AP2M1) were significantly related to cell proliferation and antigen processing.In imatinib-resistant CML cells,ATO could influence genes related to cell adhesion,AMN107 might affect genes involved in cellular carbohydrate metabolism,and the combination therapy might regulate genes involved in cell proliferation.

In this study, a rapid and sensitive analytical method was developed for the determination of 10 major compounds (procyanidin B1, catechin, procyanidin B2, rutin, isoquercitrin, kaempferol-3-O-rutinoside, astragalin, quercitrin, quercetin, and kaempferol) in Tetrastigma hemsleyanum by using ultra-performance liquid chromatography coupled with triple-quadrupole tandem mass spectrometry (UPLC-MS/MS) in multiple-reaction monitoring (MRM) mode. UPLC-MS/MS assay with negative ion mode was performed on a Waters CORTECS C18 (2.1 mm x 100 mm, 1.6 μm) with the mobile phase consisting of acetonitrile (A) and 0.1% aqueous formic acid (B) in gradient elution at a flow rate of 0.25 mL · min(-1) and the column temperature was set at 45 °C. Under the optimized chromatographic conditions, good separation for 10 target compounds were obtained including chiral isomer procyanidins B1 and B2 were completely separated within 8.5 min. Satisfactory linearity was achieved with wide linear range and fine determination coefficient (r > 0.996 6), the overall recoveries were ranged from 95.44%-110.40% with the RSD ranging from 2.37%-8.69%. It is the first report about simultaneous analysis of 10 major flavonoids components in Tetrastigma hemsleyanum by using UPLC-MS/MS method, which affords highly sensitive, specific, speedy and efficient method for quality control of Tetrastigma hemsleyanum

1H NMR metabonomics approach was used to reveal the chemical difference of urine between patients with Xiao-Chaihu Tang syndrome (XCHTS) and healthy participants (HP). The partial least square method was used to establish a model to distinguish the patients with Xiao-Chaihu-Tang syndrome from the healthy controls. Thirty-four endogenous metabolites were identified in the 1H NMR spectrum, and orthogonal partial least squares discriminant analysis showed the urine of patients with Xiao-Chaihu Tang syndrome and healthy participants could be separated clearly. It is indicated that the metabolic profiling of patients with Xiao-Chaihu Tang syndrome was changed obviously. Fifteen metabolites were found by S-pot of OPLS-DA and VIP value. The contents of leucine, formic acid, glycine, hippuric acid and uracil increased in the urine of patients, while threonine, 2-hydroxyisobutyrate, acetamide, 2-oxoglutarate, citric acid, dimethylamine, malonic acid, betaine, trimethylamine oxide, phenylacetyl glycine, and uridine decreased. These metabolites involve the intestinal microbial balance, energy metabolism and amino acid metabolism pathways, which is related with the major symptom of Xiao-Chaihu Tang syndrome. The patients with Xiao-Chaihu Tang syndrome could be identified and predicted correctly using the established partial least squares model. This study could be served as the basis for the accurate diagnostic and reasonable administration of Xiao-Chaihu-Tang syndrome.

OBJECTIVETo investigate the effect of Dachengqi Decoction (DCQD) on the key signaling molecules in lung and large intestine of mice with endotoxemia for exploring the exterior-interior relation between Fei and Dachang.

METHODSA total of 32 BALB/c mice were randomly and equally allocated into four groups: mice in Group C and D were made into endotoxemia model by intraperitoneal injection of 10 mg/kg lipopolysaccharide (LPS); while those in Group A and B were not modeled but given intraperitoneal injection of saline instead. Thirty min after then, saline to Group A and C, and DCQD to Group B and D were given by gastric infusion, and mice were sacrificed 6 h later. Their tissues of lung and large intestine were taken for observing pathological changes by inverted microscopy with HE staining; detecting expressions of tumor necrosis factor-alpha (TNF-alpha) by LiquiChip system; determining gene transcription and protein expression of toll-like receptor 4 (TLR4) using reverse transcription-polymerase chain reaction (RT-PCR) and Western blot, and the correlation of TNF-alpha and TLR4 levels in the lung and the large intestine tissue was analyzed. RESULTED: Compared with Group C, hemorrhage, pathologic toxemic features, including pulmonary edema and inflammatory cell infiltration as well as intestinal wall congestion and neutrophil infiltration, were significantly alleviated in Group D. Levels of TNF-alpha expression, TLR4 protein expression and gene transcription raised significantly in the modeled mice (P < 0.01), but comparison between the two modeled groups showed that the three parameters were lower in Group D than in Group C (P < 0. 01 or P < 0.05) respectively. Correlation analysis showed that the levels of TNF-alpha expression, TLR4 protein expression and gene transcription in pulmonary tissues were positively correlated with those in large intestinal tissues respectively (r = 0.973, P < 0.01, r = 0.906, P < 0.01, and r = 0.880, P < 0.01).

CONCLUSIONSThe effects of DCQD in alleviating pulmonary and large intestinal inflammation induced by endotoxemia might be correlated to its reduction on levels of TNF-alpha expression, TLR4 protein expression and gene transcription. Levels of the three parameters in the lung are correlated with the corresponding levels in the large intestine, which suggested the existence of exterior-interior relation between Fei and Dachang.
