Abstract
Multiplexed genetic perturbations are critical for testing functional interactions among coding or non-coding genetic elements. Compared to double-stranded DNA cutting, repressive chromatin formation using CRISPR interference (CRISPRi) avoids genotoxicity and is more effective for perturbing non-coding regulatory elements in pooled assays. However, current CRISPRi pooled screening approaches are limited to targeting one to three genomic sites per cell. We engineer an Acidaminococcus Cas12a (AsCas12a) variant, multiplexed transcriptional interference AsCas12a (multiAsCas12a), that incorporates R1226A, a mutation that stabilizes the ribonucleoprotein-DNA complex via DNA nicking. The multiAsCas12a-KRAB fusion improves CRISPRi activity over DNase-dead AsCas12a-KRAB fusions, often rescuing the activities of lentivirally delivered CRISPR RNAs (crRNA) that are inactive when used with the latter. multiAsCas12a-KRAB supports CRISPRi using 6-plex crRNA arrays in high-throughput pooled screens. Using multiAsCas12a-KRAB, we discover enhancer elements and dissect the combinatorial function of cis-regulatory elements in human cells. These results instantiate a group testing framework for efficiently surveying numerous combinations of chromatin perturbations for biological discovery and engineering.

Abstract
Multiplexed genetic perturbations are critical for testing functional interactions among coding or non-coding genetic elements. Compared to double-stranded DNA cutting, repressive chromatin formation using CRISPR interference (CRISPRi) avoids genotoxicity and is more effective for perturbing non-coding regulatory elements in pooled assays. However, current CRISPRi pooled screening approaches are limited to targeting 1-3 genomic sites per cell. To develop a tool for higher-order ( > 3) combinatorial targeting of genomic sites with CRISPRi in functional genomics screens, we engineered an Acidaminococcus Cas12a variant -- referred to as mul tiplexed transcriptional interference AsCas12a (multiAsCas12a). multiAsCas12a incorporates a key mutation, R1226A, motivated by the hypothesis of nicking-induced stabilization of the ribonucleoprotein:DNA complex for improving CRISPRi activity. multiAsCas12a significantly outperforms prior state-of-the-art Cas12a variants in combinatorial CRISPRi targeting using high-order multiplexed arrays of lentivirally transduced CRISPR RNAs (crRNA), including in high-throughput pooled screens using 6-plex crRNA array libraries. Using multiAsCas12a CRISPRi, we discover new enhancer elements and dissect the combinatorial function of cis-regulatory elements. These results instantiate a group testing framework for efficiently surveying potentially numerous combinations of chromatin perturbations for biological discovery and engineering.

Abstract
Zishen Pill (ZSP) is a traditional Chinese medicine that is frequently used to treat Benign Prostatic Hyperplasia (BPH), however its specific mechanism of action and active ingredients are yet unknown. We used a combination of serum pharmacochemistry and network pharmacology and a series of biochemical assays to explore the action mechanism of ZSP in the treatment of BPH. The BPH rat model was created using testosterone propionate, and following oral ZSP administration, the components of ZSP in rat serum were detected by UPLC-Q-Exactive Orbitrap/MS method. A "component-target-disease" network and PPI networks were constructed on this foundation. The primary mechanism of ZSP decreasing BPH in rats was studied by KEGG pathway and GO analysis. Finally, the potential pathways and key targets were further verified in vivo by molecular biology and immunological methods. 46 substances were charactered from rat serum, and 164 anti-BPH targets were screened from the database. According to network pharmacology, the primary targets were CASP3, STAT3, JUN, and PTGS2/COX2. Three related pathways (PI3K/Akt signaling pathway, AGE-RAGE signaling pathway and EGFR tyrosine kinase inhibitor resistance) were closely related to the therapeutic effects of ZSP. The findings of molecular biology demonstrated that ZSP may bring Bcl-2, BAX, CASP3, COX2, and 5LOX protein and gene expression in BPH rats appreciably closer to that of normal rats. Additionally, ZSP can lessen the expression of inflammatory cytokines in BPH rats, including VEGF, TNF-α, CCL5, and interleukin. CONCLUSION: The above results suggest that ZSP may reduce BPH through inflammation/immunity and apoptosis/proliferation-related pathways. This study offers a fresh approach to investigate the basic pharmacological effects and mechanism of ZSP in the treatment of BPH.

Abstract
Alzheimer's disease (AD) is an irreversible neurodegenerative disease that affects more than 44 million people worldwide. The pathogenic mechanisms of AD still remain unclear. Currently, there are numerous studies investigating the microbiota-gut-brain axis in humans and rodents indicated that gut microbiota played a role in neurodegenerative diseases, including AD. However, the underlying relationship between the progress of AD disease and the dynamic distribution of gut microbiota is not well understood. In the present study, APPswe /PS1ΔE9 transgenic mice of different ages and sex were employed. After the evaluation of the AD mice model, gut metagenomic sequencing was conducted to reveal gut microbiota, moreover, probiotics intervention was treated in the AD mice. The results showed that (1) AD mice had reduced microbiota richness and a changed gut microbiota composition, and AD mice gut microbiota richness was correlated with cognitive performance. We have also found some potential AD-related microbes, for example, in AD-prone mice, the genus Mucispirillum was strongly associated with immune inflammation. (2) Probiotics intervention improved cognitive performance and changed gut microbiota richness and composition of AD mice. We revealed the dynamics distribution of gut microbiota and the effect of probiotics on AD in a mice model, which provides an important reference for the pathogenesis of AD, intestinal microbial markers associated with AD, and AD probiotic intervention.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Flavonoids are the main components of the traditional Chinese medicine Anemarrhenae Rhizoma (dried rhizome of Anemarrhena asphodeloides Bge.), which has been reported to possess activity against inflammation and tumor. AIM OF STUDY Regulation of the arachidonic acid (AA) cascade through cyclooxygenase (COX) and lipoxygenase (LOX) represent the two major pathways to treat inflammatory of benign prostatic hyperplasia (BPH). In this study, Anemarrhenae Rhizoma flavonoids and its main compounds (mangiferin, neomangiferin and isomangiferin) were investigated for effects on AA metabolism. METHODS Ultra-performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS) was used to monitor AA metabolites in BPH rats and in PC-3 cells. COX-2 and 5-LOX protein and mRNA levels were measured by Western blot and qPCR, respectively, along with histopathological assessment of prostate tissues. RESULTS Treatment with flavonoids significantly ameliorated BPH-associated prostate inflammation and inhibited the expression of COX-2 and 5-LOX at the protein and mRNA levels. Quantitative metabolomic analysis of blood plasma showed flavonoids treatment decreased AA levels and its metabolites associated with the COX and LOX pathways. Further exploration of the flavonoid compounds mangiferin, neomangiferin and isomangiferin showed they inhibited AA metabolism to varying degrees in PC-3 cell cultures. CONCLUSION Anemarrhenae Rhizoma flavonoids act to inhibit BPH-related inflammation in vivo and in vitro by targeting AA metabolism and interfering with COX and LOX pathways. The identification of mangiferin, neomangiferin and isomangiferin as anti-inflammatory components suggests flavonoids interventions represent a promising therapeutic approach for BPH.

Abstract
BACKGROUND The bioactive alkaloids identified from Cortex Phellodendri (CP) were highly effective in treating rats with benign prostatic hyperplasia (BPH). Specifically, lipoxygenase-5 (LOX-5) and cyclooxygenase-2 (COX-2) were identified as two primary targets for alleviating inflammation in BPH rats. However, it remains unknown whether the alkaloid components in CP can interact with the two target proteins. PURPOSE To further identify bioactive alkaloids targeting LOX/COX pathways. METHODS An affinity-ultrafiltration mass spectrometry approach was employed to screen dual-target LOX-5/COX-2 ligands from alkaloid extract. The structures of bioactive alkaloids were characterized by high-resolution Fourier transform ion cyclotron resonance mass spectrometry. To understand the molecular mechanisms underlying the effects of bioactive alkaloids, the expression levels of LOX-5 and COX-2 in BPH model rats were investigated at both protein and mRNA levels. The LOX-5/COX-2 enzymes activity experiments and molecular docking analysis were performed to fully evaluate the interactions between bioactive alkaloids and LOX-5/COX-2. RESULTS After comprehensive analysis, the results showed that bioactive alkaloids could suppress the expression of LOX-5 and COX-2 simultaneously to exert an anti-inflammatory effect on the progression of BPH. In addition, the screened protoberberine, demethyleneberberine was found to exhibit prominent inhibitory activities against both LOX-5 and COX-2 enzymes, palmatine and berberine with moderate inhibitory activities. Molecular docking analysis confirmed that demethyleneberberine could interact well with LOX-5/COX-2. CONCLUSION This study is the first to explore the inhibitory effects of bioactive alkaloids from CP on LOX-5 and COX-2 activities in BPH rats. Our findings demonstrate that the bioactive alkaloids from CP can ameliorate BPH via dual LOX-5/COX-2 pathways, which serves as an efficient approach for the discovery of novel drug leads from natural products with reduced side effects.

Abstract
BACKGROUND Opioids have been prescribed to reduce suffering from pain and to enhance quality of life. Due to the addictive potential and the lack of other effective alternatives to treat severe acute and chronic pains, opioids remain a serious public health issue. While, opioids directly influence the drug-seeking behavior, tolerance and withdrawal processes, through neuroadaptation, the brain's endogenous opioid system also adapts in the presence of chronic pain and could contribute to the difficulty of treatment. Despite the seemingly obvious interaction between the presence of pain and opioid-abuse, little is known about the underlying mechanisms in the brain. PURPOSE To review the current understanding of the interaction mechanisms of neurotransmitter circuitries in pain modulation and reward in the brain and the effects of L-tetrahydropalmatine (L-THP) and its metabolites in pain management and opioid use disorder and gain a better insight on the pharmacological profile and in vivo effects of L-THP and its metabolites. METHOD A detailed literature search on available (preclinical and clinical) studies about the effects of L-THP and its metabolites against drug addiction and chronic pain has been performed. The data was collected using various search engines such as PubMed, ScienceDirect, Google scholar and articles in English up to December 2020 were included in this review. RESULTS L-THP and its metabolites demonstrated analgesic and anti-addiction effects. Due to their dual pharmacological properties (D1 partial agonist and D2 antagonist) these compounds could be used as molecular tools to provide a better understanding of the interactions between pain and addiction. CONCLUSION The available data confirms the potential of L-THP and its metabolites to treat both chronic pain and drug addiction. However, further clinical trials are needed to establish safety and efficacy.

Abstract
l-Tetrahydropalmatine (l-THP), an active alkaloid compound isolated from Rhizoma Corydalis-yanhusuo, has been reported to possess biological activity for treating cocaine use. To enhance both oral bioavailability and brain penetration, three formulations of l-THP suspension, mixture of l-THP-puerarin and self-microemulsifying drug delivery systems (SMEDDS) were prepared. A sensitive and reliable ultra-high-performance liquid chromatography with tandem mass spectrometry method was developed and validated for the simultaneous determination of l-THP and its active metabolite l-isocorypalmine (l-ICP) in rat brain. Diazepam was used as the internal standard. The chromatographic separation was achieved on a Bonshell ASB C18 column at 30°C using acetonitrile-aqueous formic acid as mobile phase in gradient mode. The linearity was validated over the concentration ranges of 4.00-2,500 ng/ml for l-THP and 0.400-500 ng/ml for l-ICP. Full method validation was within the acceptance limits. The method was successfully used to determine the pharmacokinetics of two analytes following oral administration of these three formulations to rats. A significant difference was observed in the main pharmacokinetic parameters between SMEDDS and the suspension, and a 3.25- and 2.97-fold increase in the relative bioavailability of l-THP and l-ICP, respectively, was observed with the SMEDDS compared with the suspension formulation. It was concluded that SMEDDS enhanced the absorption of l-THP and l-ICP and delayed their release in brain.

Abstract
BACKGROUND Modulation of the arachidonic acid (AA) cascade via 5-lipoxygenase (5-LOX) and cyclooxygenase-2 (COX-2) represent the two major pathways for treatments of inflammation and pain. The design and development of inhibitors targeting both 5-LOX and COX-2 has gained increasing popularity. As evidenced, 5-LOX and COX-2 dual targeted inhibitors have recently emerged as the front runners of anti-inflammatory drugs with improved efficacy and reduced side effects. Natural products represent a rich resource for the discovery of dual targeted 5-LOX and COX-2 inhibitors. By combining affinity ultrafiltration and high-performance liquid chromatography-mass spectrometry (AUF-LC-MS), an efficient method was developed to identify spirostanol glycosides and furostanol glycosides as the 5-LOX/COX-2 dual inhibitors from saponins extract of Anemarrhenae Rhizoma (SEAR). METHODS A highly efficient method by combining affinity ultrafiltration and high-performance liquid chromatography-mass spectrometry (AUF-LC-MS) was first developed to screen and characterize the 5-LOX/COX-2 dual targeted inhibitors from SEAR. The structures of compounds in the ultrafiltrate were characterized by high resolution Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR-MS). In addition, in vitro 5-LOX/COX-2 inhibition assays and their dual expression in vivo were performed to confirm the inhibitory activities of the compounds screened by AUF-LC-MS. Molecular docking studies with the corresponding binding energy were obtained which fit nicely to both 5-LOX and COX-2 protein cavities and in agreement with our affinity studies. RESULTS A total of 5 compounds, timosaponin A-II, timosaponin A-III, timosaponin B-II, timosaponin B-III and anemarrhenasaponin I, were identified as potential 5-LOX/COX-2 dual targeted inhibitors with specific binding values > 1.5 and IC50 ≤ 6.07 μM. CONCLUSION The present work demonstrated that spirostanol glycoside and furostanol glycoside were identified as two novel classes of dual inhibitors of 5-LOX/COX-2 enzymes by employing a highly efficient screening method of AUF-LC-MS. These natural products represent a novel class of anti-inflammatory agents with the potential of improved efficacy and reduced side effects.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Zi-shen pill (ZSP), a traditional Chinese medicine, is widely used for the treatment of benign prostatic hyperplasia (BPH) and has remarkable curative effect. AIM OF THE STUDY To screen the potential 5-Lipoxygenase(5-LOX) inhibitors from ZSP extract. MATERIALS AND METHODS A new approach based on affinity ultrafiltration-ultra performance liquid chromatography-mass spectrometry(UPLC-MS) was established and validated. Zileuton and glipizide were chosen as positive and negative control drug, respectively. For better screening result, the concentration of 5-LOX enzyme, incubation temperature and time, pH and ion strength were optimized. In addition, 5-LOX inhibitory assay in vitro and molecular docking technique were used for further verification. RESULTS 20 compounds were characterized in the ultrafiltrate by high resolution Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) and 16 ligands showed binding ability to 5-LOX. Among them, six ligands were deduced as high-potential 5-LOX inhibitors with their high specific binding values (>2.0). The inhibitory activities of anemarrhenasaponin I, timosaponin AI, nyasol and demethyleneberberine were confirmed by the 5-LOX inhibitory assay for validating the reliability of affinity ultrafiltration approach and the computer-simulated molecular docking technique further clarified the possible mechanism of action between the active compounds and the 5-LOX active sites.

Abstract
The structural evolution of the equilibrium and supercooled Cu46Zr54 liquids was investigated with a combination of elastic neutron scattering (with isotopic substitution) and synchrotron x-ray scattering studies. The partial pair correlation functions were determined over a wide temperature range (∼270 °C). These show that the Cu-Cu and Zr-Zr ordering increases as the temperature decreases, while the Cu-Zr ordering decreases. This surprising result is in contradiction with the results from molecular dynamics studies.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Zi-shen pill (ZSP) is a classical Chinese herbal formula used for treatment of benign prostatic hyperplasia (BPH). AIM OF THE STUDY To characterize and screen cyclooxygenase-2 (COX-2) inhibitors from ZSP extract. MATERIALS AND METHODS The ZSP extract was incubated with COX-2 and the potential ligands were screened out by affinity ultrafiltration. Celecoxib and glipizide were chosen as positive control and negative control drug, respectively. Affinity ultrafiltration-ultra performance liquid chromatography-mass spectrometry (UPLC-MS) method was used. In addition, in vitro COX-2 inhibitory assay and in silico molecular docking technique were used for further validation. RESULTS A total of 20 components were discovered and identified from ZSP ultrafiltrate by high resolution Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS), among which 8 compounds were deduced as potential COX-2 inhibitors by their high specific binding values (>1.5). Inhibitory activities of demethyleneberberine, palmatine, berberine and timosaponin A-I were confirmed by an enzyme assay of COX-2, which validated the reliability of our approach. Molecular docking simulation investigated potential mechanism of action for these compounds. CONCLUSION The results revealed that affinity ultrafiltration UPLC-MS could successfully screen out the potential COX-2 inhibitors from complex Chinese herbal formula ZSP extract, indicating that its therapeutic effect on BPH was partly based on the enzyme active ingredients.

Abstract
UNLABELLED We applied tandem mass tag (TMT)-based proteomics to investigate protein changes in bone marrow microenvironment of osteoporotic patients undergoing spine fusion. Multiple bioinformatics tools were used to identify and analyze 219 differentially expressed proteins. These proteins may be associated with the pathogenesis of osteoporosis. INTRODUCTION Bone marrow microenvironment is indispensable for the maintenance of bone homeostasis. We speculated that alterations of some factors in the microenvironment of osteoporotic subjects might influence the homeostasis. This study aimed to investigate the changes in the expression of protein factors in the bone marrow environment of osteoporosis. METHODS We performed a proteomics analysis in the vertebral body-derived bone marrow supernatant fluid from 8 Chinese patients undergoing posterior lumbar interbody fusion (4 osteoporotic vs. 4 non-osteoporotic) and used micro-CT to analyze the microstructural features of spinous processes from these patients. We further performed western blotting to validate the differential expressions of some proteins. RESULTS There was deteriorated bone microstructure in osteoporotic patients. Based on proteomics analysis, 172 upregulated and 47 downregulated proteins were identified. These proteins had multiple biological functions associated with osteoblast differentiation, lipid metabolism, and cell migration, and formed a complex protein-protein interaction network. We identified five major regulatory mechanisms, splicing, translation, protein degradation, cytoskeletal organization, and lipid metabolism, involved in the pathogenesis of osteoporosis. CONCLUSIONS There are various protein factors, such as DDX5, PSMC2, CSNK1A1, PLIN1, ILK, and TPM4, differentially expressed in the bone marrow microenvironment of osteoporotic patients, providing new ideas for finding therapeutic targets for osteoporosis.

Abstract
To reveal the material basis of Huo Luo Xiao Ling Dan (HLXLD), a sensitive and selective ultra-high performance liquid chromatography coupled with quadrupole-time-of-flight mass spectrometry (UHPLC-Q-TOF/MS) method was developed to identify the absorbed components and metabolites in rat plasma after oral administration of HLXLD. The plasma samples were pretreated by liquid-liquid extraction and separated on a Shim-pack XR-ODS C18 column (75 × 3.0 mm, 2.2 μm) using a gradient elution program. With the optimized conditions and single sample injection of each positive or negative ion mode, a total of 109 compounds, including 78 prototype compounds and 31 metabolites, were identified or tentatively characterized. The fragmentation patterns of representative compounds were illustrated as well. The results indicated that aromatization and hydration were the main metabolic pathways of lactones and tanshinone-related metabolites; demethylation and oxidation were the major metabolic pathways of alkaloid-related compounds; methylation and sulfation were the main metabolic pathways of phenolic acid-related metabolites. It is concluded the developed UHPLC-Q-TOF/MS method with high sensitivity and resolution is suitable for identifying and characterizing the absorbed components and metabolites of HLXLD, and the results will provide essential data for further studying the relationship between the chemical components and pharmacological activity of HLXLD.

Abstract
It is widely, although not universally, believed that there must be a connection between liquid dynamics and the structure. Previous supporting studies, for example, have demonstrated a link between the structural evolution in the liquid and kinetic fragility. Here, new results are presented that strengthen the evidence for a connection. By combining the results from high-energy synchrotron X-ray scattering studies of containerlessly processed supercooled liquids with viscosity measurements, an accelerated rate of structural ordering beyond the nearest neighbors in the liquid is demonstrated to correlate with the temperature at which the viscosity transitions from Arrhenius to super-Arrhenius behavior. This is the first confirmation of predictions from several recent molecular dynamics studies.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Huo Luo Xiao Ling Dan (HLXLD), a traditional Chinese medicine (TCM), is commonly used for the treatment of rheumatoid arthritis (RA). AIM OF THE STUDY To explore the potential therapeutic mechanism of HLXLD on anti-inflammatory activity. MATERIALS AND METHODS A metabolomic approach based on UFLC-MS/MS to profile arachidonic acid (AA) metabolic changes was used. The cyclooxygenase (COX) and lipoxygenase (LOX) catalyzed metabolites in plasma were quantified on 7, 14, 21, and 28 days after the rats injected with Complete Freund's adjuvant and orally administrated with HLXLD, methotrexate and dexamethasone in parallel as the positive control drugs. RESULTS Nineteen metabolites involved in COX and LOX pathways in RA model group were significant increased compared with normal group (P < 0.05), including 12-hydroxyeicosatetraenoic acid (12-HETE), 15-HETE, 8-HETE, leukotriene B4(LTB4), prostaglandin E2 (PGE2), PGI2, PGD2, PGF2α, thromboxane B2 (TXB2), etc. From day 7 to day 28, the trajectory direction of HLXLD group and positive control groups gradually moved towards the initial space, and the concentrations of AA and its metabolites after HLXLD treatment were significantly reduced in dual pathways compared to control groups. CONCLUSION HLXLD induced a substantial change in the AA metabolic profiles through refrain the expression of COX and LOX. The present investigation also highlights that distinct ingredients of this formula tend to inhibit different target to achieve a therapeutic effect.

Abstract
In mammals, the microbiota can be transmitted from the placenta, uterus, and vagina of the mother to the infant. Unlike mammals, development of the avian embryo is a process isolated from the mother and thus in the avian embryo the gut microbial developmental process remains elusive. To explore the establishment and inheritance of the gut microbiome in the avian embryo, we used the chicken as the model organism to investigate the gut microbial composition in embryos, chicks, and maternal hens. We observed: (1) 28 phyla and 162 genera of microbes in embryos where the dominated genus was Halomonas (79%). (2) 65 genera were core microbiota in all stages with 42% and 62% gut microbial genera of embryo were found in maternal hen and chick, respectively. There was a moderate correlation (0.40) between the embryo and maternal, and 0.52 between the embryo and chick at the family level. (3) Gut microbes that are involved in substance metabolism, infectious disease, and environmental adaptation are enriched in embryos, chicks, and maternal hens, respectively. (4) 94% genera of gut microbial composition were similar among three different chicken breeds which were maintained under similar conditions. Our findings provide evidence to support the hypothesis that part of the microbial colonizers harbored in early embryos were inherited from maternal hens, and the gut microbial abundance and diversity were influenced by environmental factors and host genetic variation during development.

Abstract
Purpose To compare the efficacy and safety of conbercept and ranibizumab when administered according to a treat-and-extend (TREX) protocol for the treatment of neovascular age-related macular degeneration (AMD) in China. Patients and methods Between May 2014 and May 2015, 180 patients were treated in a 1 : 1 ratio using conbercept or ranibizumab from four hospitals. Patients received either conbercept 0.5 mg or ranibizumab 0.5 mg intravitreal injections. Follow-up time was 1 year and treated based on a TREX approach. Main outcomes and measures include best-corrected visual acuity (BCVA), using Early Treatment Diabetic Retinopathy Study (ETDRS); number of injections; central retinal thickness (CRT); and leakage of choroidal neovascularization before and after the treatment was analyzed by fluorescein fundus angiography and indocyanine green angiography. Results The 1-year visit was completed by 168 (93.3%) of patients. Mean BCVA was equivalent between two cohorts, and were improved by 12.7±7.770 and 12.3±7.269 letters in the conbercept and ranibizumab cohorts, respectively (P=0.624). There was no significant difference in measured CRT, with a mean decrease of 191.5 μm for conbercept and 187.8 μm for ranibizumab (P=0.773). There was a statistically significant difference (P=0.001) between the drugs regarding the number of treatments: 7.4 for conbercept and 8.7 for ranibizumab. The difference in the distribution of injection intervals was statistically significant between two groups (P=0.011). During the study, there were no cases of endophthalmitis or intraocular inflammation. Conclusion Both drugs had equivalent effects in visual and anatomic gains at 1 year when administered. In the conbercept group, longer treatment intervals were achieved with more patients.

Abstract
To explore coevolution between the gut microbiota and the humoral immune system of the host, we used chickens as the model organism. The host populations were two lines (HAS and LAS) developed from a common founder that had undergone 40 generations of divergent selection for antibody titers to sheep red blood cells (SRBC) and two relaxed sublines (HAR and LAR). Analysis revealed that microevolution of host humoral immunity contributed to the composition of gut microbiota at the taxa level. Relaxing selection enriched some microorganisms whose functions were opposite to host immunity. Particularly, Ruminococcaceae and Oscillospira enriched in high antibody relaxed (HAR) and contributed to reduction in antibody response, while Lactobacillus increased in low antibody relaxed (LAR) and elevated the antibody response. Microbial functional analysis showed that alterations were involved in pathways relating to the immune system and infectious diseases. Our findings demonstrated co-microevolution relationships of host-microbiota and that gut microorganisms influenced host immunity.

Abstract
Polydactyly, a common heritable limb malformation in vertebrates, is characterized by supernumerary digits. In chickens, basic characteristics and rough dominant genes have been explored in past decades; however, the elaborate pattern of inheritance and the determinant gene remain obscure. In this study, different types of polydactylism were classified by the numbers and the shapes of toes, including the newly defined subtypes of B’ and G, for the Beijing fatty chicken, a native breed of chicken from China. Through experiments on hybridization, we demonstrated a complete dominant inheritance of polydactyly instead of an incomplete penetrance or genetic modification of the previous conjecture. In particular, by using the F2 population of the five-digit purebred line of Beijing fatty chicken backcrossed to Shiqiza chicken and by using restriction-site associated DNA based markers, we performed a genome-wide association study on the trait of polydactyly. Furthermore, whole genome resequencing strategy was applied to sweep SNPs across the whole genome. An outlier-based Fst approach was employed to search for signatures of selection, and results indicated that the determinant mutation was found in the region ranging from 8.3 Mb to 8.7 Mb, where the polydactyly candidate gene LMBR1 was located. The G/T mutation of rs80659072 was identified to be highly associated with polydactyly in our resequencing and was validated in random samples from an expanded population. Thus, we confirmed that LMBR1 was the causative gene of polydactyly in the Beijing fatty chicken by using GWAS with restriction-site associated DNA based markers and resequencing.

Abstract
A sensitive and reliable ultra-high-performance liquid chromatography with tandem mass spectrometry (UHPLC-MS/MS) method was developed and validated for simultaneous determination of l-tetrahydropalmatine (l-THP) and its active metabolites l-isocorypalmine (l-ICP) and L-corydalmine (l-CD) in rat plasma. The analytes were extracted by liquid-liquid extraction and separated on a Bonshell ASB C18 column (2.1 × 100 mm; 2.7 μm; Agela) using acetonitrile-formic acid aqueous as mobile phase at a flow rate of 0.2 mL/min in gradient mode. The method was validated over the concentration range of 4.00-2500 ng/mL for l-THP, 0.400-250 ng/mL for l-ICP and 1.00-625 ng/mL for l-CD. Intra- and inter-day accuracy and precision were within the acceptable limits of <15% at all concentrations. Correlation coefficients (r) for the calibration curves were >0.99 for all analytes. The quantitative method was successfully applied for simultaneous determination of l-THP and its active metabolites in a pharmacokinetic study after oral administration with l-THP at a dose of 15 mg/kg to rats.

Abstract
We describe a method for the targeted analysis of bioactive arachidonic acid metabolites through cyclooxygenase (COX) and lipoxygenase (LOX) pathway in knee joint, liver, kidney, spleen and heart using an ultra-fast liquid chromatography-tandem mass (UFLC-MS/MS) method. Method validation was investigated, including linearity, precision, accuracy, matrix effect, extraction recovery and stability for the simultaneous analysis of prostaglandins (PGs), thromboxanes (TXs), leukotrienes (LTs) and hydroxyeicosatetraenoic acids (HETEs). The method enables us to chromatographically separate branched-chain species from their straight-chain isomers as well as separate biologically important eicosanoids. The concentrations of the following major eicosanoids were significantly increased in rheumatoid arthritis model rats than in normal ones: 5-HETE, 8-HETE, 12-HETE, 15-HETE, PGF2α, TXB2, 5-HpETE, LTE4, PGE2, PGD2, LTB4. Further multivariate data analysis (partial least square-discriminant analysis) showed COX products (PGs, TXs) were readily distributed towards liver and kidney, LOX products (LTs, HETEs) towards knee joint and spleen, and heart had no characteristic metabolites. The method described here offers a useful tool for the evaluation of complex regulatory eicosanoids responses in RA disease states and provides support for use of dual inhibitors of COX and LOX enzymes on RA treatment.

Abstract
BACKGROUND/PURPOSE The detectors from Courage & Khazaka and DermaLab® from Cortex Technology were two series of the most commonly used non-invasive instruments for the skin physiological properties measurements. The aim of this study is to reveal the differences and correlations in measuring skin color, hydration, transepidermal water loss (TEWL), sebum and elasticity on the forearm or faces between two commercially available series of instruments. METHODS 30 subjects were enrolled to be measured by the two series of instruments. The measurements by each series were performed on the left/right side of the body randomly. The hydration, sebum, elasticity and TEWL measurements were performed on different sites. RESULTS Positive correlations were found in the values of skin color, hydration, TEWL, sebum and visco-elasticity detected by the two series. The values related to skin firmness measured by the two instruments were statistically negative correlated. Contrary to the results in measuring the skin color, the detectors from Courage & Khazaka presented lower values of variation in measuring skin hydration and TEWL than those from DermaLab® . CONCLUSION The two series have significant correlations.The differences of the two series can be due either to differences in the design of the probe or left/right part of the body.

Here, we report de novo whole-genome assemblies for the goose and swan goose and describe the evolutionary relationships among 7 bird species, including domestic and wild geese, which diverged approximately 3.4~6.3 million years ago (Mya). In contrast to chickens as a proximal species, the expanded and rapidly evolving genes found in the goose genome are mainly involved in metabolism, including energy, amino acid and carbohydrate metabolism. Further integrated analysis of the host genome and gut metagenome indicated that the most widely shared functional enrichment of genes occurs for functions such as glycolysis/gluconeogenesis, starch and sucrose metabolism, propanoate metabolism and the citrate cycle. We speculate that the unique physiological abilities of geese benefit from the adaptive evolution of the host genome and symbiotic interactions with gut microbes.

Abstract
Porcine epidemic diarrhea (PED) is a devastating disease in livestock industry. Most of the previous studies related to the PED were focused on the pathology and etiology of porcine epidemic diarrhea virus (PEDV). A little was known regarding the status of gut microbiota after piglets infected by PEDV. In this study, aided by metagenome sequencing technology, gut microbiota profiles in feces of viral diarrhea (VD) and viral control (VC) piglets were investigated. The results showed that the abundance of four dominant phyla (Fusobacteria, Actinobacteria, Verrucomicrobia, and Proteobacteria) in feces was affected greatly by porcine epidemic diarrhea. Especially, the abundance of Fusobacteria was higher in VD piglets (36%) than in VC piglets (5%). On the contrary, the Verrucomicrobia was detected in lower distribution proportion in VD piglets (around 0%) than in VC piglets (20%). Furthermore, 25 genera were significantly different between VC and VD piglets at the genus level. Among the 25 genera, Leptotrichia belonging to Fusobacteria was remarkably lower in VC piglets than in VD piglets. Akkermansia belonging to Verrucomicrobia was higher in VC piglets than in VD piglets. Our findings implicated that the gut microbiota associated with PED significantly provided an insight into the pathology and physiology of PED.

Abstract
A simple, reliable and rapid ultra-performance liquid chromatography-tandem mass spectrometry method was developed and validated for the simultaneous quantification of four secoiridoid (gentiopicroside, swertiamarin, sweroside) and iridoid glycosides (loganic acid), the bio-active ingredients in rat plasma. After liquid-liquid extraction, chromatographic separation was accomplished on a Shim-pack XR-ODS column with a mobile phase consisting of methanol and 0.1% formic acid in water. A triple quadrupole tandem mass spectrometry equipped with an electrospray ionization source was used as detector operating both in positive and negative ionization mode and operated by multiple-reaction monitoring scanning. The lower limits of quantitation were 0.25-30 ng/mL for all the analytes. Both intra-day and inter-day precision and accuracy of analytes were well within acceptance criteria (±15%). The mean extraction recoveries of analytes and internal standard (amygdalin) from rat plasma were all >71.4%. The validated method was successfully applied to a comparative pharmacokinetic study of four analytes in rat plasma between normal and arthritic rats after oral administration of Huo Luo Xiao Ling Dan and Gentiana macrophylla extract, respectively. Results showed significant differences in pharmacokinetic properties of the analytes among the different groups.

Abstract
The synthesis of a new series of C-2-alkyl-2-methoxymethyl-salvinorin ethers and their binding affinities at κ-, μ-, and δ-opioid receptors are presented. We have developed a synthesis that enables installation of alkyl-substituents at C-2 while maintaining the integrity of the C-2 methoxymethyl ether and retaining κ-opioid receptor binding activity. Among these new compounds, 2-methyl-2-methoxymethyl-salvinorin ether (9a) is a potent full agonist at the κ receptor and shows comparable potency in Ki and EC50 with salvinorin A and U50488H. These C2-alkylated analogs have been identified as full κ agonists.

Abstract
Hepatocarcinogenesis is a complex process involving chronic liver injury, inflammation, unregulated wound healing, subsequent fibrosis and carcinogenesis. To decipher the molecular mechanism underlying transition from chronic liver injury to dysplasia, we investigated the oncogenic role of gankyrin (PSMD10 or p28GANK) during malignant transformation in a transgenic mouse model. Here, we find that gankyrin increased in patients with cirrhosis. In addition to more severe liver fibrosis and tumorigenesis after DEN plus CCl4 treatment, hepatocyte-specific gankyrin-overexpressing mice (gankyrinhep) exhibited malignant transformation from liver fibrosis to tumors even under single CCl4 administration, whereas wild-type mice merely experienced fibrosis. Consistently, enhanced hepatic injury, severe inflammation and strengthened compensatory proliferation occurred in gankyrinhep mice during CCl4 performance. This correlated with augmented expressions of cell cycle-related genes and abnormal activation of Rac1/c-jun N-terminal kinase (JNK). Pharmacological inhibition of the Rac1/JNK pathway attenuated hepatic fibrosis and prevented CCl4-induced carcinogenesis in gankyrinhep mice. Together, these findings suggest that gankyrin promotes liver fibrosis/cirrhosis progression into hepatocarcinoma relying on a persistent liver injury and inflammatory microenvironment. Blockade of Rac1/JNK activation impeded gankyrin-mediated hepatocytic malignant transformation, indicating the combined inhibition of gankyrin and Rac1/JNK as a potential prevention mechanism for cirrhosis transition.

Abstract
The objective of this study was to develop a sensitive and reliable ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method for simultaneous quantitation of three monoterpene glycosides (paeoniflorin, alibiflorin and oxypaeoniflorin) and four alkaloids (tetrahydropalmatine, corydaline, dehydrocorydaline and berberine), the main active ingredients of Radix Paeoniae Rubra extract (RPE) and Corydalis yanhusuo extract (CYE) in Huo Luo Xiao Ling Dan (HLXLD), and to compare the pharmacokinetics of these active ingredients in normal and arthritic rats orally administrated with HLXLD or RPE/CYE alone. The analytes and internal standard (IS) (geniposide) were separated on a XBridge C18 column (150 × 4.6 mm, 3.5 µm) using gradient elution with the mobile phase consisting of methanol and 0.01% formic acid in water at a flow rate of 0.6 ml/min. The detection of the analytes was performed on Acquity UPLC-MS/MS system with an electrospray ionization and multiple reaction monitoring mode via polarity switching between negative (for monoterpene glycosides) and positive (for alkaloids) ionization mode. The lower limits of quantification were 2.5, 1, 0.5, 0.2, 0.2, 0.02 and 0.01 ng/ml for paeoniflorin, alibiflorin, oxypaeoniflorin, tetrahydropalmatine, corydaline, dehydrocorydaline and berberine, respectively. Intra-day and inter-day precision and accuracy of analytes were well within acceptance criteria (15%). The mean extraction recoveries of analytes and IS from rat plasma were all more than 83.1%. The validated method has been successfully applied to determination of the analytes. Results showed that there were remarkable differences in pharmacokinetic properties of the analytes between herbal formula and single herb group, normal and arthritic group.

Abstract
Huo Luo Xiao Ling Dan (HLXLD), a Chinese herbal formula composed of 11 different herbs, has been used traditionally for the treatment of arthritis and other chronic inflammatory diseases. However, the pharmacokinetic profile of its anti-inflammatory bioactive compounds has not been elucidated. Boswellic acids are the bioactive compounds with potent anti-inflammatory activity isolated from Boswellia serrate which is one of the 11 herbs of HLXLD. The objective of the study was to compare the pharmacokinetics of the two bioactive bowsellic acids: 11-keto-β-boswellic acid and 3-O-acetyl-11-keto-β-boswellic following oral administration of HLXLD or Boswellia serrata extract alone in normal and arthritic rats. An LC-MS method was developed and validated for the determination of 11-keto-β-boswellic acid and 3-O-acetyl-11-keto-β-boswellic in the comparative pharmacokinetic study. The results showed that there were significant differences in pharmacokinetic parameters between normal and arthritic groups. Interestingly, the absorptions of two boswellic acids were significantly higher in HLXLD than Boswellia serrata extract alone, indicating the synergistic effect of other herbal ingredients in HLXLD. This comparative pharmacokinetic study provided direct evidence supporting the notion that the efficacy of a complex mixture such as HLXLD is better than that of single components in treating human diseases.

Abstract
OBJECTIVE To compare the contents of lignin in crude and processed fruits of Schisandrae chinensis, and to explore the processing mechanism of S. chinensis fruits. METHOD Contents of schisandrin, schisandrol B, deoxyschisandrin, gomisin N, gamma-schizandrin and schisandrin C were determined by high performance liquid chromatography (HPLC). RESULT Except the content of Schisandrol B was higher or less in processed fruits than that in the crude, the other lignin contents of S. chinensis fruits in different processed products were higher than that in the crude. The alcohol-processed product had the highest content of lignin. CONCLUSION The contents of lignin have changed by different processed methods, and alcohol-processed method may be the best processed method.
