Abstract
Hawthorn has the efficacy of eliminating turbidity and lowering the blood lipid level, and it is used for treating hyperlipidemia in clinic. However, the bioactive components of hawthorn are still unclear. In this study, the spectrum-effect relationship was employed to screen the bioactive components of hawthorn in the treatment of hyperlipidemia, and then the bioactive components screened out were verified in vivo. Furthermore, the quality control method for hawthorn was developed based on liquid chromatography-mass spectrometry(LC-MS). The hyperlipidemia model of rats was built, and different polar fractions of hawthorn extracts and their combinations were administrated by gavage. The effects of different hawthorn extract fractions on the total cholesterol(TC), triglycerides(TG), and low-density lipoprotein-cholesterol(LDL-C) in the serum of model rats were studied. The orthogonal projections to latent structures(OPLS) algorithm was used to establish the spectrum-effect relationship model between the 24 chemical components of hawthorn and the pharmacodynamic indexes, and the bioactive components were screened out and verified in vivo. Finally, 10 chemical components of hawthorn, including citric acid and quinic acid, were selected to establish the method for evaluating hawthorn quality based on LC-MS. The results showed that different polar fractions of hawthorn extracts and their combinations regulated the TG, TC, and LDL-C levels in the serum of the model rats. The bioactive components of hawthorn screened by the OPLS model were vitexin-4″-O-glucoside, vitexin-2″-O-rhamnoside, rutin, citric acid, malic acid, and quinic acid. The 10 chemical components of hawthorn, i.e., citric acid, quinic acid, rutin, gallic acid, vitexin-4″-O-glucoside, vitexin-2″-O-rhamnoside, malic acid, vanillic acid, neochlorogenic acid, and fumaric acid were determined, with the average content of 38, 11, 0.018, 0.009 5, 0.037, 0.017, 8.1, 0.009 5, 0.073, and 0.98 mg·g~(-1), respectively. This study provided a scientific basis for elucidating the material basis of hawthorn in treating hyperlipidemia and developed a content determination method for evaluating the quality of hawthorn.

Abstract
Typhae Pollen (TP) and its carbonized product (carbonized Typhae Pollen, CTP), as cut-and-dried herbal drugs, have been widely used in the form of slices in clinical settings. However, the two drugs exhibit a great difference in terms of their clinical efficacy, for TP boasts an effect of removing blood stasis and promoting blood circulation, while CTP typically presents a hemostatic function. Since the active ingredients of CTP, so far, still remain unclear, this study aimed at identifying the active ingredients of CTP by spectrum-effect relationship approach coupled with multi-block partial least squares (MBPLS), partial least squares (PLS), and support vector machine (SVM) algorithms. In this study, the chemical profiles of a series of CTP samples which were stir-fried for different duration (denoted as CTP0∼CTP9) were firstly characterized by UHPLC-QE-Orbitrap MS. Then the hemostatic effect of the CTP samples was evaluated from the perspective of multiple parameters-APTT, PT, TT, FIB, TXB2, 6-keto-PGF1α, PAI-1 and t-PA-using established rat models with functional uterine bleeding. Subsequently, MBPLS, PLS and SVM were combined to perform spectrum-effect relationship analysis to identify the active ingredients of CTP, followed by an in vitro hemostatic bioactivity test for verification. As a result, a total of 77 chemical ingredients were preliminarily identified from the CTP samples, and the variations occurred in these ingredients were also analyzed during the carbonizing process. The study revealed that all the CTP samples, to a varying degree, showed a hemostatic effect, among which CTP6 and CTP7 were superior to the others in terms of the hemostatic effect. The block importance in the projection (BIP) indexes of MBPLS model indicated that flavonoids and organic acids made more contributions to the hemostatic effect of CTP in comparison to other ingredients. Consequently, 9 bioactive ingredients, including quercetin-3-O-glucoside, kaempferol-3-O-rutinoside, quercetin, kaempferol, isorhamnetin, 2-methylenebutanedioic acid, pentanedioic acid, benzoic acid and 3-hydroxybenzoic acid, were further identified as the potential active ingredients based on PLS and SVM models as well as the in vitro verification. This study successfully revealed the bioactive ingredients of CTP associated with its hemostatic effect, and also provided a scientific basis for further understanding the mechanism of TP processing. In addition, it proposed a novel path to identify the active ingredients for Chinese herbal medicines.

Abstract
This study was aimed at identifying the bioactive components of the crude and stir-baked hawthorn for invigorating spleen and promoting digestion, respectively, to clarify the processing mechanism of hawthorn by applying the partial least squares(PLS) algorithm to build the spectrum-effect relationship model. Firstly, different polar fractions of crude and stir-baked hawthorn aqueous extracts and combinations of different fractions were prepared, respectively. Then, the contents of 24 chemical components were determined by ultra-high performance liquid chromatography-mass spectrometry. The effects of different polar fractions of crude hawthorn and stir-baked hawthorn aqueous extracts and combinations of different fractions were evaluated by measuring the gastric emptying rate and small intestinal propulsion rate. Finally, the PLS algorithm was used to establish the spectrum-effect relationship model. The results showed that there were significant differences in the contents of 24 chemical components for different polar fractions of crude and stir-baked hawthorn aqueous extracts and combinations of different fractions, and the gastric emptying rate and small intestinal propulsion rate of model rats were improved by administration of different polar fractions of crude and stir-baked hawthorn aqueous extracts and combinations of different fractions. The bioactive components of crude hawthorn identified by PLS models were vitexin-4″-O-glucoside, vitexin-2″-O-rhamnoside, neochlorogenic acid, rutin, gallic acid, vanillic acid, citric acid, malic acid, quinic acid and fumaric acid, while neochlorogenic acid, cryptochlorogenic acid, rutin, gallic acid, vanillic acid, citric acid, quinic acid and fumaric acid were the bioactive components of stir-baked hawthorn. This study provided data support and scientific basis for identifying the bioactive components of crude and stir-baked hawthorn, and clarifying the processing mechanism of hawthorn.

Abstract
In August 2016, continuous measurements of volatile organic compounds (VOCs) and trace gases were conducted at an urban site in Wuhan. Four high-ozone (O3) days and twenty-seven non-high-O3 days were identified according to the China's National Standard Level II (∼100 ppbv). The occurrence of high-O3 days was accompanied by tropical cyclones. Much higher concentrations of VOCs and carbon monoxide (CO) were observed on the high-O3 days (p < 0.01). Model simulations revealed that vehicle exhausts were the dominant sources of VOCs, contributing 45.4 ± 5.2% and 37.3 ± 2.9% during high-O3 and non-high-O3 days, respectively. Both vehicle exhausts and stationary combustion made significantly larger contributions to O3 production on high-O3 days (p < 0.01). Analysis using a chemical transport model found that local photochemical formation accounted for 74.7 ± 5.8% of the daytime O3, around twice the regional transport (32.2 ± 5.4%), while the nighttime O3 was mainly attributable to regional transport (59.1 ± 9.9%). The local O3 formation was generally limited by VOCs in urban Wuhan. To effectively control O3 pollution, the reduction ratio of VOCs to NOx concentrations should not be lower than 0.73, and the most efficient O3 abatement could be achieved by reducing VOCs from vehicle exhausts. This study contributes to the worldwide database of O3-VOC-NOx sensitivity research. Its findings will be helpful in formulating and implementing emission control strategies for dealing with O3 pollution in Wuhan.

Abstract
The system model of Chinese herbal medicine process is the basis for improving the precision of pharmaceutical process and ensuring the stable transmission of quality between different sections of the process. By taking the wet granulation-tableting process as the research object and using the Panax notoginsengs sapions (PNS) as a model drug, multi-block partial least squares method (MBPLS) was used in this article to build the system model of Chinese herbal medicine process, analyze the mass transmission rules in the process and improve the understanding on pharmaceutical process system of Chinese medicine. According to the process flow, the quality attributes of raw materials, granules and tablets collected in the process were divided into different data blocks, and the MBPLS method was used to establish system model. The R²Y and Q²Y of MBPLS model were 89.1% and 65.5%, respectively, indicating that the performance of the MBPLS model was good. By analyzing the parameters of MBPLS model, it was determined that the physical quality attributes of PNS raw materials and quality attributes of PNS granules were the key factors to affect the quality of PNS tablets. The particle size, bulk density and tapped density of PNS raw materials were the critical quality attributes which caused the quality variations of PNS granules and PNS tablets. MBPLS can quantify the contributions of each unit to the product quality by dividing the quality attributes into different units. It was helpful to analyze the interactions between the process units of Chinese herbal medicine and it could be applied to build system model of other Chinese herbal preparations processes.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Traditional Chinese medicine (TCM) has been widely used in China and its surrounding countries in clinical treatments for centuries-long time. However, due to the complexity of TCM constituents, both action mechanism and material base of TCM remain nearly unknown. AIM OF THE STUDY The present study was designed to uncover the action mechanism and material base of TCM in a low-cost manner. MATERIALS AND METHODS Compound Danshen dripping pills (DSP) is a widely used TCM for treatment of atherosclerosis, and was researched here to demonstrate the effectiveness of our method. We constructed a heterogeneous network for DSP, identified the significant network module, and analyzed the primary pharmacological units by performing GO and pathways enrichment analysis. RESULTS Two significant network modules were identified from the heterogeneous network of DSP, and three compounds out of four hub nodes in the network were found to intervene in the process of atherosclerosis. Moreover, 13 out of 20 enriched pathways that were ranked in top 10 corresponding to both the two pharmacological units were found to be involved in the process of atherosclerosis. CONCLUSIONS Quercetin, luteolin and apigenin may be the main active compounds which modulate the signaling pathways, such as metabolism of xenobiotics by cytochrome P450, retinol metabolism, etc. The present method helps reveal the action mechanism and material base of DSP for treatment of atherosclerosis.

Abstract
A simple and reliable method of high-performance liquid chromatography with photodiode array detection (HPLC-DAD) was developed to evaluate the quality of a traditional Chinese medicine Sophora flavescens through establishing chromatographic fingerprint and simultaneous determination of five flavonoids, including trifolirhizin, maackiain, kushenol I, kurarinone and sophoraflavanone G. The optimal conditions of separation and detection were achieved on an ULTIMATE XB-C18 column (4.6 mm x 250 mm, 5 microm) with a gradient of acetonitrile and water, detected at 295 nm. In the chromatographic fingerprint, 13 peaks were selected as the characteristic peaks to assess the similarities of different samples collected from different origins in China according to similarity evaluation for chromatographic fingerprint of traditional chinese medicine (2004AB) and principal component analysis (PCA) were used in data analysis. There were significant differences in the fingerprint chromatograms between S. flavescens and S. tonkinensis. Principal component analysis showed that kurarinone and sophoraflavanone G were the most important component. In quantitative analysis, the five components showed good regression (R > 0.999) with linear ranges, and their recoveries were in the range of 96.3% - 102.3%. This study indicated that the combination of quantitative and chromatographic fingerprint analysis can be readily utilized as a quality control method for S. flavescens and its related traditional Chinese medicinal preparations.

Abstract
OBJECTIVE To establish a new method for quality evaluation and validate its feasibilities by simultaneous quantitative assay of five alkaloids in Sophora flavescens. METHOD The new quality evaluation method, quantitative analysis of multi-components by single marker (QAMS), was established and validated with S. flavescens. Five main alkaloids, oxymatrine, sophocarpine, matrine, oxysophocarpine and sophoridine, were selected as analytes to evaluate the quality of rhizome of S. flavescens, and the relative correction factor has good repeatibility.

Abstract
PURPOSE The aim of this meta-analysis and systematic review was to determine whether bleeding prophylaxis benefits patients after colonoscopic polypectomy. METHODS A systematic review of the literature was performed to find prospective randomized controlled trials of postpolypectomy hemorrhage prophylaxis. Studies were selected according to specific criteria and analyzed to generate pooled data. RESULTS Eight studies encompassing 2,595 polyps met the criteria for the meta-analysis. The rate of early bleeding was significantly decreased relative to the control when a single prophylactic technique was used [2.58% vs. 8.15%, OR = 0.34 (95% CI, 0.20-0.58), P < 0.0001]. The use of multiple prophylactic techniques resulted in a lower early postpolypectomy hemorrhage rate compared with the use of a single prophylactic technique [0% vs. 8.41%, OR = 0.12 (95% CI, 0.03-0.47), P = 0.002]. The late bleeding rate did not differ significantly between the monotherapy and control groups [0.61% vs. 1.39%, OR = 0.37 (95% CI, 0.11-1.28), P = 0.12], and the use of combined preventative techniques did not significantly decrease the late postpolypectomy bleeding (PPB) rate compared with use of a single prophylactic method [1.43% vs. 2.05%, OR = 0.70 (95% CI, 0.32-1.55), P = 0.38]. CONCLUSION Prophylactic endoscopic treatments are effective at reducing early PPB after colonoscopic polypectomy. However, patients with late PPB may not benefit from bleeding prophylaxis.

Abstract
OBJECTIVE To assess emodin antagonism to cerebral ischemia injury, and to discuss the mechanism of emodin inhibiting the inflammatory cascade reaction from the levels and expressions of cytokines. METHOD Rats were divided into sham-operated group, model group, Ligustrazine group and emodin groups (low, middle, high dosage). After focal cerebral ischemic model of cerebral middle artery occlusion was duplicated with nylon thread, we took the speciments after ischemia 6 hours, observed the changes of the evaluating score of neural symptoms, brain water ratio and cerebral infarction area, determined the levels of TNF-alpha, IL-beta and TGF-beta in rats brain tissue by radioimmunoassay, detected the expressions of TNF-alpha and VCAM-1 by immunohistochemistry, and measured VCAM-1-mRNA expression by in-situ hybridization. RESULT Compared with sham-operated group, the evaluating score of neural symptoms, brain water ratio and cerebral infarction area of rats in model group were higher (P < 0.01) , the levels of TNF-alpha and IL-1beta of rats brain tissue in model group increased, while the level of TGF-beta was lower, and the expressions of TNF-alpha and VCAM-1 increased (P < 0.01). The evaluating score of neural symptoms, brain water ratio and cerebral infarction area improved obviously in every emodin group, especially in emodin low dosage group. Levels of TNF-alpha, IL-1beta and the expressions of TNF-alpha and ICAM-1 in emodin low dosage group and Ligustrazine group were lower, while the level of TGF-beta was higher. Compared with Ligustrazine group, the changes aboved are more significant in emodin low dosage group (P < 0.01). CONCLUSION The increase of inflammatory cascade reaction mediated by various cytokines such as TNF, IL-1beta, ICAM-1 and the decrease of TGF protection are the important mechanism of cerebral ischemia injury. The mechanism of emodin antagonism to cerebral ischemia injury may be implemented by inhibiting inflammatory cascade reaction and increasing the brain protective factors, such as TGF.

Abstract
AIM To increase the production of recombinant truncated form of insulin-like growth factor I [des(1-3)IGF-I], purify the expressed product, and compare its bioactivity with that of standard IGF-I. METHODS The second copy of des(1-3)IGF-I gene was inserted into the previously constructed pExSec1/IGF-I to form a pExSec1/2(IGF-I) expression plasmid, then the plasmid was transformed into a protease-deficient E coli strain BL21(DE3). The engineered bacteria were cultured and induced by IPTG at 12 degrees C. The expressed product was purified through ultrafiltration and Sephadex G-50 gelfiltration. The bioactivity of the preliminarily purified protein was tested by MTT method and compared with standard IGF-I. RESULTS The amount of des(1-3)IGF-I expressed by pExSec1/2(IGF-I) reached up to 20 % of the total soluble bacterial protein, which was higher than the amount (12 %) expressed by a single copy of pExSec1/IGF-I gene. The purity of recombinant des(1-3)IGF-I reached 49 % and 82 % after ultrafiltration and gelfiltration. The bioactivity of des(1-3)IGF-I after gelfiltration was about 77 % of standard IGF-I at the same concentration. CONCLUSION The yield of recombinant des(1-3)IGF-I was increased about 8 % by construction of expression plasmid with two copies of des(1-3)IGF-I gene compared with only one copy of gene, and preliminarily purified des(1-3)IGF-I showed about 77 % bioactivity compared with standard IGF-I.

Abstract
OBJECTIVE Past studies have found that environmental stress affects cellular immune function and that extensive variability exists in the magnitude and direction of stress-induced immune changes. Past research also suggests that individuals with greater right, relative to left, resting frontal electroencephalogram (EEG) activation perceive environmental stress as more aversive and have lower baseline cellular immune function. In this study, we examined environmental stressors, resting frontal EEG laterality, and immune responses to short-term psychological stressors in adolescent boys. METHODS A sample of twenty-four 14-16 year old right-handed boys underwent a recording of resting EEG and collections of blood taken before and after a laboratory protocol designed to induce psychological stress. Blood samples were used to measure changes in mitogen lymphoproliferative responses, natural killer (NK) cell activity, and T-cell phenotypic subsets. Life events were measured using self-report questionnaires. RESULTS Life events and frontal laterality showed a first order interaction in predicting changes in lymphocyte proliferation to tetanus toxoid (R2 increment = .26, p < .01) and pokeweed mitogen (R2 increment = .25, p < .02). The interaction also predicted changes in NK activity (R2 increment = .24, p < .02). CONCLUSIONS Changes in lymphocyte proliferation and NK activity were associated with negative life events only among individuals with greater left frontal cortical activation. Our results suggest that recent psychosocial stress and individual differences in resting frontal cortical activation are together linked to immunologic responses to acute psychological stressors.

Abstract
BACKGROUND Risk behavior contributes to injuries, one of the most important sources of morbidity and mortality in adolescents. Although research has shown that environmental stress makes adolescents more likely to engage in risk behavior and to sustain injuries, the magnitude of these associations has been small. Little is known about the role of individual differences in psychobiologic reactivity to stress in moderating the impact of stressful events. In this study, we examined associations among environmental stressors, cardiovascular reactivity to stress, and the level of risk behavior in adolescent boys. METHODS Twenty-four 14- to 16-year-old boys underwent a laboratory protocol designed to measure responses to psychologically and physically stressful tasks. Changes in heart rate and mean arterial blood pressure were measured serially at standard points in the protocol, and levels of positive and negative life events and recent risk behavior were measured using self-report questionnaires. RESULTS Neither life events nor cardiovascular reactivity were independently associated with risk behavior. Positive life events and mean arterial blood pressure reactivity significantly interacted, however, in predicting risk behavior (R2 increment = .25). Boys with high reactivity who reported numerous positive life events engaged in markedly less risk behavior than their peers. CONCLUSION We conclude that adolescents with exaggerated cardiovascular responses to laboratory stressors are associated with less risk behavior in a setting of positive life circumstances. This result suggests that reactivity may exert protective, rather than harmful, influences in some environments.

Abstract
Recent psychobiologic research has provided new insights into the interplay between constitutional and environmental etiologies in stress-induced childhood illness. Individual differences in both psychobiologic reactivity and physiologic self-regulation may substantially influence a child's internal stress responses. In addition, the physiologic consequences of a given environmental stressor may depend critically on the developmental stage in which the stressor occurs. Behavioral changes associated with early exposures to stressors may be linked to alterations in central nervous system monoamine production and metabolism. Evidence for developmental and psychobiologic changes in response to very early, even prenatal, stressors suggests that environmental and genetic contributions to stress response profiles may ultimately be difficult to disentangle.

Abstract
In this study, the effects of midazolam (M), diazepam (D) and thiopentone (T) on respiratory and cardiovascular systems were compared. The patients were randomly divided into 6 groups, besides minute ventilatory volume (MV), onset of induction and cardiovascular changes were also observed. Induction was performed by a bolus injection of one of the following: midazolam (0.3 mg/kg), diazepam (0.3 mg/kg) or thiopentone (5 mg/kg). Five minutes later, 5 micrograms/kg fentanyl and 1.5-2.0 mg/kg succinylcholine were administered. The results showed that: (1) Inhibitory effect on MV was not prominent and similar after use of midazolam and diazepam but was remarkable after thiopental; (2) As for the onset, midazolam was faster than diazepam but slower than thiopentone; (3) Hemodynamic changes of midazolam, diazepam and thiopentone were similar, however during intubation, cardiovascular response was the least in midazolam, diazepam the intermediate and thiopentone the most significant. We conclude that midazolam is a water-soluble, safe and effective inductive anesthetic with its short eliminated half-life period, and much lesser venous irritation, and it is certainly superior to both diazepam and thiopentone.
