Abstract
Objective: To investigate the clinicopathological features and molecular characteristics of β-catenin-deficient colorectal cancer. Methods: The clinical, pathological and molecular features of 11 colorectal cancers with β-catenin protein loss diagnosed at the 960th Hospital of People's Liberation Army of China, from January 2012 to November 2022 were analyzed. Results: Among the 11 patients, 3 were males and 8 were females. Their age ranged from 43 to 74 years, with the median age of 59 years. Six were in the left colon and 5 were in the right colon. One of the 11 cases had lymph node metastasis, 10 cases were well and moderately differentiated adenocarcinoma, and 1 was mucinous adenocarcinoma. Eight cases were of TNM stage T4, 2 of T1 stage and 1 of Tis stage. β-catenin protein was not detected using immunohistochemistry. Sanger sequencing revealed the presence of fragment-deletion mutation in exon 3 of CTNNB1 gene, resulting in loss of β-catenin protein expression. Conclusion: β-catenin deficiency is present in a small number of colorectal cancers and may be associated with exon 3 mutations of CTNNB1 gene.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Artemisia mongolica is well known for its use in folk medicine, it is commonly used to alleviate a variety of diseases associated with inflammation, such as laryngitis, tonsillitis, headaches and hepatitis in northwest China. However, its anti-inflammatory mechanism is still unknown. AIM OF THE STUDY The most potential anti-inflammatory part (AMPA) was identified by screening individual parts of A. Mongolica. After the network pharmacological analysis, the anti-inflammation effects and molecular mechanisms of AMPA were evaluated in RAW264.7 cells induced by LPS. MATERIALS AND METHODS AMPA was chosen as the most anti-inflammatory of the A. Mongolica, as measured by the effect of each part of the A. Mongolica on NO and COX-2. The chemical composition of AMPA was identified using HPLC-Q-TOF-MS/MS, and targets of bioactive chemicals and targets related to inflammation were found using open-source databases. The "Compound-targets" network and PPI network were established by combining compounds and overlapped targets, and targets in the PPI networks were analyzed by GO and KEGG enrichment. The RAW26.7 cells induced by LPS were used as a model of inflammation examination. MTT assay was performed to assess the cytotoxicity of AMPA on LPS-induced RAW264.7 cells. The level of NO was measured by the Griess method while the inflammatory factors were detected by ELISA. The protein expression levels of iNOS, COX-2, MAPK, NF-κB signaling pathway and AMPK/Nrf2-related proteins were determined by Western blot. The results of nuclear translocation of p65 and Nrf2 were analyzed by immunofluorescence assay. RESULTS A total of 18 compounds with potential bioactivity were identified, and after intersecting 640 compound-predicted targets and 1608 inflammation targets, the compounds and intersected targets were utilized to structure "compound-target" and PPI networks. Among AMPA, AM6, AM7, AM11, AM8 and AM1 compounds were essential in the "compound-targets" network, meanwhile, TNF, RELA, MAPK1, NOS2, PRKAG, and PTGS2 targets play important roles in the PPI network. The top 10 terms and pathways were obtained based on GO and KEGG. The cell experiments show that 50 μg/mL was the maximum concentration of AMPA without cytotoxicity in the LPS-induced RAW264.7 cell model. When compared with the LPS group, AMPA treatment not only effectively suppressed the generation of NO, TNF-α, IL-6, PGE2, IL-1β and MCP-1 in LPS-induced RAW264.7 cells, but also down-regulated the expression of COX-2, iNOS and the protein levels p-ERK, p-p38, p-IκB-α and p-p65, inhibited the nuclear translocation of p65. Furthermore, the expression levels of p-LKB1, p-AMPK, Nrf2 and HO-1 proteins were up-regulated and Nrf2 nuclear translocation was promoted. CONCLUSION AMPA should be considered an anti-inflammatory agent for the results of network pharmacology and in vitro, which could inhibit the MAPK pathway and NF-κB pathway and activate the AMPK/Nrf2 pathway in LPS-stimulated RAW264.7 cells.

Abstract
INTRODUCTION Fungal species are an attractive resource for physiologically functional food and drug precursor. Fomes officinalis Ames, a medicinal fungus, is traditionally used as a folk medicine in traditional Chinese medicine prescription for the therapy of cough and asthma. The water-soluble substances in Chinese herbal medicines are likely to play an important physiological function. However, information on probing and identifying chemical components of the aqueous extract of Fomes officinalis Ames (AFO) remains unknown. OBJECTIVE This study was conducted to screen and characterise the chemical components of AFO. MATERIAL AND METHODS An effective and sensitive ultrahigh-performance liquid chromatography tandem quadrupole-Orbitrap high-resolution mass spectrometry (UHPLC-Q-Orbitrap-HRMS) method with the Full MS/PIL/dd-MS2 acquisition approach was applied for the profiling of chemical components in AFO. An HSS T3 column was used for component separation, and a strategy of simultaneous targeted and untargeted multicomponent characterisation was implemented. Multiple identification approaches were used, including accurate molecular mass and elemental composition matching, literature and database searching, and fragmentation rules elucidation. RESULTS A total of 115 components, including 20 amino acids and derivatives, six nucleobases, nine nucleosides, 75 dipeptides, two tripeptides, and three other components, were tentatively identified. Among them, the targeted exploring method screened six nucleobases and nine nucleosides including modified nucleosides. To our best knowledge, this is the first time a report has been done on the presence of the 115 compounds in AFO. CONCLUSION Profiling and characterisation compounds of AFO enriched its material basis, which would lay the foundation for improving potential medicinal and nutritional values and effecting comprehensive quality control of Fomes officinalis Ames.

Abstract
Capitula of Coreopsis tinctoria are widely used as a flower tea with great health benefits due to rich content of flavonoids and phenolic acids. The hepatoprotective effect of C. tinctoria and its bioactive basis have seldom been investigated until now. In the present study, capitula of C. tinctoria were extracted with a method optimized by response surface methodology (RSM) and BoxBehnken design (BBD) and further purified by macroporous resin HPD-300 to obtain a fraction (CE) enriched with flavonoids and phenolic acids. The contents of the four most abundant compounds, isookanin-7-O-β-d-glucoside (1), quercetigetin-7-O-β-d-glucoside (2), okanin (3), and marein (4), were determined by HPLC as 9.98, 5.21, 41.78 and 1.85 mg/g, respectively. Seventy-four compounds including fifity-five flavonoids, fifteen organic acids (twelve of them were phenolic compounds), and three coumarins were tentatively identified in CE by LC-HRMS/MS. In vivo hepatoprotective effect and potential mechanism of CE were studied with a high-fat diet-induced NASH mouse model. CE administration decreased the amount of weight gain, hepatic lipid, and sequentially improved dyslipidemia, inflammation, oxidative stress, and IR in HFD-fed mice. Molecular data revealed that CE inhibited hepatic inflammation by reducing NFκB/iNOS/COX-2/NLRP3/MAPK in the liver tissues and ameliorated oxidative stress by activating the Nrf2/HO-1 pathway. Modulation of inflammation and oxidative stress with CE may represent a promising target for the treatment of NAFLD and provide insight into the mechanism by which CE protects against obesity.

Abstract
OBJECTIVES Patient safety incidents can impact not only patients and families but also healthcare providers, who may experience negative emotions and symptoms, such as anxiety, guilt, stress, and loss of confidence. To identify and support these "second victims," a screening tool called the Second Victim Experience and Support Tool (SVEST) has been developed. This scoping review aims to map our current knowledge of the SVEST in terms of its scope of use, validation and limitations. STUDY DESIGN Scoping review. METHODS In accordance with the framework outlined by Arksey and O'Malley and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for Scoping Reviews, we conducted a literature search in MEDLINE, CINAHL, Cochrane Library, SCOPUS, Embase and PsycINFO databases from database inception up till 1 March 2023. RESULTS A total of 31 studies were reviewed. The SVEST has been cross-culturally adapted from English into other languages. The SVEST has been successfully used in different contexts and with various healthcare professionals, including doctors, nurses, allied health professionals, midwives and pharmacists. The tool has been used to assess the impact of second victim experiences and the effectiveness of support interventions in addressing the phenomenon. Validity assessment of translated versions of SVEST in the reviewed studies revealed good content validity in most cases, although some studies did not report clear values for scale-level Content Validity Index. On the whole, SVEST is generally a reliable and valid tool, although further refinements and modifications may improve its validity and reliability. CONCLUSIONS The review highlights the significance of SVEST as a crucial resource for healthcare providers and organisations that prioritise well-being and safety in health care. It also underscores the importance of recognising the needs of second victims and offering them appropriate interventions to manage the aftermath of adverse events.

Abstract
BACKGROUND Xuelian granule (XL), a traditional Chinese medicine (TCM) formula, has been used for the treatment of diabetic nephropathy for a long time as a hospital preparation. Because the active ingredients in the XL that can help to treat diabetic nephropathy are still unclear, which limits the interpretation for its pharmacological mechanism, further development and subsequent study on the material basis of its efficacy. METHODS In this study, a screening method based on inhibition activity against aldose reductase (AR) was employed for activity-directed chemical analysis of XL using ultra-high performance liquid chromatography combined with quadrupole-orbitrap high resolution mass spectrometry (UHPLC-Q-orbitrap-HRMS) technique. RESULTS A total of 178 compounds, including 46 terpenes, 47 organic acids, 25 flavonoids, 29 phenylethanoid glycosides, and 31 other types, were tentatively identified from XL which might responsible for its AR inhibition activity. CONCLUSION This is the first study for a systematic, rapid, and accurate qualitative analysis of XL. This research provides a scientific and experimental basis for further researches on pharmacodynamics material basis and quality control of XL.

Abstract
Seven previously undescribed guaianolides, millefolactons A-G, and three known analogues, millefoliumins A-C, were isolated from the whole plant of Achillea millefolium L. growing in Xinjiang, China. Their structures were elucidated using the HR-ESI-MS and NMR data analyses. The absolute configurations of millefolactons A-G were determined by single-crystal X-ray crystallography, ECD data analysis, and quantum-chemical ECD calculations. Millefolactons A-E are rare 3-oxa-guaianolides. Millefolacton C, millefolacton E, millefoliumin A and millefoliumin B exhibited enzymatic inhibition of 15-LOX. Molecular docking simulations were conducted to visualize interactions between the four active compounds and 15-LOX and determine binding mechanisms. Moreover, a LPS-induced BV2 cell model was used to further investigate the anti-inflammatory mechanism of millefolacton C. As a result, millefolacton C significantly inhibited NO release, repressed levels of pro-inflammatory cytokines including TNF-α, IL-18, PGE2 and IL-6, and inhibited the protein expression of iNOS and COX2 proteins. In addition, millefolacton C could potently decreased the expression of NLRP3, ASC, and IL-1β proteins in LPS-stimulated BV2 cells. These results indicate that the 3-oxa-guaianolides from A. millefolium L. offer great potential as leads for anti-inflammatory drug development.

Abstract
Matricarla chamomilla L. is native to European countries and widely cultivated in China, especially in Xinjiang. It has been used in Uygur medicine for the treatment of cough caused by asthma. In this study, UHPLC-Q-Orbitrap-MS was used to detect and identify the components from the active fraction of M. Chamomile, 64 compounds were identified by combining the standards, related literatures and mass spectrometry fragments, including 10 caffeoyl quinic acids, 38 flavonoids, 8 coumarins, 5 alkaloids and 3 other compounds. Furtherly, the anti-asthma activity of active fraction of M. Chamomile was investigated in OVA-induced allergic asthma rat model. The results showed that the number of EOS in Penh and bronchoalveolar lavage fluid (BALF) in the group of the active fraction of M. Chamomile was significantly lower than that in the model group. Besides, the active fraction of M. Chamomile can significantly reduce the IgE level and increased glutathione peroxidase (GSH-Px) in the serum of OVA-induced rats, and ameliorated OVA-induced lung injury. Hence, M. Chamomile could be used to treat asthma through their in vivo antioxidant and anti-inflammatory effects. This study explored the potential material basis of M. Chamomile for the treatment of asthma.

Abstract
The phytochemical study of Limonium gmelinii roots resulted in the isolation of five lignanamides (1-5). Among them, limoniumins J, K, and M (1, 2, and 4) are undescribed compounds, limoniumin L (3) is a new naturally occurring lignanamide, and limoniumin B (5) is a known compound which showed PTP1B inhibition activity with an IC50 value of 5.05 ± 2.44 μM in our previous work. Spectroscopic data analysis, including 1D and 2D NMR and HRESIMS experiments, established the chemical structures of limoniumins J - M (1-4). Compounds 1-4 showed PTP1B inhibition activity, among which compound 3 showed the most potent PTP1B inhibition with an IC50 value of 2.07 ± 0.05 μM. Compounds 3 and 5 could significantly increase cellular glucose consumption and glucose uptake in L6 muscle cells and could synergize with insulin to promote glucose consumption and glucose uptake in a concentration-dependent manner. The treatment of compound 3 also promoted glycogen synthesis in skeletal muscle cells. Western blot analysis demonstrated that the good hypoglycemic effect of compounds 3 and 5 was achieved by activating PI3K/AKT signaling pathway to promote glucose consumption, glucose uptake, and glycogen synthesis. Furthermore, studies on molecular docking revealed the potent interactions between these bioactive substances and the PTP1B protein.

Abstract
The composite material based on N-, S-, and Fe-doped TiO2 (NSFe-TiO2) synthesized by wet impregnation was used as a photocatalyst to rapidly degrade sulfadiazine. The photocatalytic degradation behavior and mechanism of sulfadiazine on NSFe-TiO2 were investigated for revealing the role of degradation under ultraviolet light. The results showed that compared with TiO2, NSFe-TiO2 markedly improved the efficiency in photocatalytic degradation of sulfadiazine: more than 90% of sulfadiazine could be removed within 120 min by NSFe-TiO2 dosage of 20 mg L-1. The process conformed to first-order reaction kinetics model. The parameters such as loaded amount of NSFe-TiO2, solution pH value, humic acid concentration and recycle numbers on removal efficiency were also studied. Compared to neutral and alkaline conditions, acidic condition was not conducive to the photocatalysis. HA, Ca2+, Cu2+ and Zn2+ in the actual water body had mild inhibition on sulfadiazine degradation in UV/NSFe-TiO2 system. Fragments screened by high-resolution mass spectrometry were conducted to explore the oxidation mechanism and pathways of sulfadiazine degradation. On the whole, UV/NSFe-TiO2 photocatalysis has a good effect on sulfadiazine removal.

Abstract
OBJECTIVES The relationship between sarcopenia and cognitive function has been extensively studied, but is usually explored at a single time point. We used repeatedly measured cognitive data to examine the relationship between sarcopenia and cognitive trajectories over time among middle-aged and older Chinese adults. DESIGN A nationally representative cohort study. SETTING AND PARTICIPANTS Data were from three waves (2011, 2013 and 2015) of the China Health and Retirement Longitudinal Study (CHARLS). A total of 8963 participants with complete baseline data (wave 1) and at least two cognitive function tests (waves 1-3) were enrolled in this study. MEASUREMENTS Sarcopenia was diagnosed at baseline (wave 1). The wave 1-3 data were used to analyze cognitive trajectories over time by constructing a latent class trajectory model (LCTM). Logistic regression model was used to analyze the association between sarcopenia and cognitive trajectories. RESULTS Among 8693 participants, we identified two trajectories of cognitive function development, including a persistent low trajectory (n= 4856, 55.86%) and a persistent high trajectory (n= 3837, 44.14%). Sarcopenia was associated with persistently low cognitive trajectory of global cognitive (OR: 1.248, 95%CI: 1.046-1.490) after adjustment for other covariates. This association was still observed when stratified by age, gender, educational level, marital status, social activity, smoking status and drinking status. Mediation analysis showed that body mass index (BMI) mediated efficacy accounting for 42.32% of the relationship. CONCLUSIONS Our study showed two trajectory groups of global cognitive function. Sarcopenia was associated with a persistent low trajectory over time and BMI mediated the relationship between sarcopenia and cognitive trajectories among middle-aged and older Chinese adults.

Abstract
This study aimed to investigate the anti-inflammatory activity of Prunus cerasifera Ehrhart (EHP). LC-MS/MS, network pharmacology, enzyme-linked immunosorbent assay (ELISA), and Western blot analysis methods were used to investigate the chemical composition and the anti-inflammatory mechanism of EHP. The LC-MS/MS results showed that flavonoids and phenolic acids were the major compounds in EHP. The network pharmacology analysis results indicated that EHP was related to TNF, inflammatory cytokine, and MAPK signaling pathway. ELISA and Western blot results showed that EHP impeded the increase in inflammatory factors, inducible nitric oxide synthase (iNOS), cyclooxygenase 2 (COX-2), nuclear transcription factors κB (p65), MAPK pathway, pyrolytic relevant proteins nod-like receptor family pyrin domain-containing 3 (NLRP3), and interleukin-1β (IL-1β) induced by lipopolysaccharide (LPS) and activated the nuclear factor erythroid 2-related factor 2 (Nrf2)/hemeoxygenase-1 (HO-1) pathway. Therefore, this research highlighted the potential application of P. cerasifera in the development of anti-inflammatory foods that prevented inflammatory diseases. PRACTICAL APPLICATIONS: In recent years, many synthetic drugs with anti-inflammatory effect have the disadvantages of high price and side effects. Thus, the development of anti-inflammatory drugs from natural resources has its application value. In this study, LPS-stimulated RAW264.7 cells were used to establish inflammatory model to verify the anti-inflammatory effect of Prunus cerasifera (EHP). The results showed that P. cerasifera possessed anti-inflammatory activity through inhibiting pro-inflammatory cytokines secretion, NF-κB, MAPK pathway, and NLRP3 inflammasome activation. Therefore, P. cerasifera has the potential to develop into functional food to prevent the progress of various inflammatory-related diseases.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Chamomile (Matricaria chamomilla L.) is a popular herbal tea for the treatment of hepatitis and cholecystitis in traditional Uygur medicines. AIM OF THE STUDY To investigate the anti-inflammatory activity and chemical composition of M. chamomilla, and clarify its molecular mechanism. MATERIALS AND METHODS M. chamomilla was extracted with 75% ethanol and then extracted with different solvents to obtain five fractions, namely petroleum ether fraction (EOPE), dichloromethane fraction (EOD), ethyl acetate fraction (EOEA), n-butanol fraction (EOB), and water fraction (EOW). Cytotoxicity and the effect on the nitric oxide (NO) production of RAW264.7 cells induced by LPS of the five fractions were screened, and the most active one (EOD) was selected for further investigations. The components of EOD were identified by LC-MS/MS analysis in combination with comparison of retention time and UV absorption with authentic compounds by HPLC. In addition, five most abundant compounds of EOD were isolation by column chromatography and semi-preparative HPLC and their structures were further confirmed by HRMS and NMR data analysis and comparison with data in literatures. Then the underlying anti-inflammatory mechanism of EOD were predicted through Network pharmacology using the identified compounds from EOD, and further verified by Western Blot and ELISA experiments. RESULTS EOD showed the most significant inhibition ratio against NO in RAW264.7 cells without toxicity among the tested five fractions. Thirty-seven compounds including flavonoid-O-glycoside, flavonoid aglycone, methylated flavonoid aglycone, phenolic acid, coumarin, sesquiterpene, and triterpene were identified from EOD by LC-MS/MS and comparison with authentic compounds. The five most abundant compounds in EOD were isolated and determined to be axillarin (26), tricin (30), chrysoeriol (31), centaureidin (33) and chrysosplenetin (35). IL-6, NF-κB, ERK1 and ERK2 cascade, TNF were the most important anti-inflammatory targets of EOD predicted by Network pharmacology. Western Blot and ELISA experiments revealed that EOD significantly decreased the protein expression levels of inflammatory factors (PGE2, MCP-1, IL-6, TNF-α), iNOS, COX-2, NF-κB (p-P65 and p-IκBα), MAPKs (p-p38, p-ERK and p-JNK), and increased the protein expression levels of Nrf2, HO-1 and CYP2E1. In addition, EOD blocked the p65 protein into the nucleus and promoted the nuclear translocation of Nrf2 in RAW264.7 cells induced by LPS. CONCLUSION M. chamomilla exerted anti-inflammatory effect via NF-κB, MAPK and Nrf2/HO-1 pathways. It could be further applied as a safe anti-inflammatory agent from natural source.

Abstract
Elaeagnus angustifolia Linnaeus is a medicinal plant and its fruit has pharmacological activity such as antiinflammatory, antiedema, antinociceptive, and muscle relaxant functions, etc. Two acidic homogeneous polysaccharides (EAP-H-a1 and EAP-H-a2) were isolated from the fruits of Elaeagnus angustifolia L. through DEAE-52 and Sephadex G-75 column chromatography, and the physicochemical, structural properties, and biological activities of the polysaccharides were investigated. Both EAP-H-a1 and EAP-H-a2 were composed of Rha, Ara, Xyl, Glc, and Gal with the molar ratios of 13.7:20.5:23.3:8.8:33.4 and 24.8:19.7:8.2:8.4:38.6, respectively, and with the molecular weights of 705.796 kDa and 439.852 kDa, respectively. The results obtained from Fourier transform infrared spectroscopy (FTIR) confirmed the polysaccharide nature of the isolated substances. Congo red assay confirmed the existence of a triple-helix structure. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) analysis revealed that EAP-H-a1 and EAP-H-a2 had irregular fibrous, filament-like surfaces; and both had crystalline and amorphous structures. Bioactivity analysis showed that the crude polysaccharide, EAP-H-a1, and EAP-H-a2 had clear DPPH and ABTS free radical scavenging activity, and could promote the secretion of NO and the phagocytic activities of RAW 264.7 and THP cells, which showed clear antioxidant and immuno-regulatory activity. These results indicated that Elaeagnus angustifolia L fruit acidic polysaccharides may have potential value in the pharmaceutical and functional food industries.

Abstract
This work aimed to develop and evaluate a post-acquisition data processing strategy, referred to as a mass defect filter (MDF), for rapid target the resin glycosides in root of Convolvulus scammonia by setting mass rang and mass defect range from high-resolution MS data. The full-scan mass data were acquired by high-performance liquid chromatography coupled with Q Exactive Plus hybrid quadrupole-orbitrap mass spectrometer that featured high resolution, mass accuracy, and sensitivity. To screen resin glycosides, three parent filter m/z 871, m/z 853, and m/z 869 combined with diagnostic fragment ions (DFIs) approach were applied to remove the interference from complex herbal extract. The targeted components were characterized based on detailed fragment ions. Using this approach, 80 targeted components, including 22 glycosidic acids and 58 resin glycosides were tentatively identified. The present results suggested that the proposed MDF strategy would be adaptable to the analysis of complex system in relevant filed.

Abstract
Vitiligo is a stubborn multifactorial skin disease with a prevalence of approximately 1% in the global population. Kaliziri, the seeds of Vernonia anthelmintica (L.) Willd., is a well-known traditional Uyghur medicine for the treatment of vitiligo. Kaliziri injections is a Chinese-marketed treatment approved by the China Food and Drug Administration for the treatment of vitiligo. The significant effects of Kaliziri injection have been thoroughly studied. However, chemical components studies and plasma quantification studies are lacking for Kaliziri injection. Ultra-high-performance liquid chromatography coupled with hybrid quadrupole orbitrap mass spectrometry was employed to comprehensively characterize the caffeoyl quinic acid derivatives present in Kaliziri injection. Based on accurate mass measurements, key fragmental ions and comparisons with reference standards, 60 caffeoyl quinic acid derivatives were identified in Kaliziri injections, including caffeoyl quinic acids, coumaroyl caffeoyl quinic acids, dicaffeoyl quinic acids, feruloyl caffeoyl quinic acids, and dicaffeoyl quinic acid hexosides. Moreover, an HPLC-MS/MS method was developed and validated for the quantitative analysis of 5-caffeoyl quinic acid, 4-caffeoyl quinic acid, 1,3-dicaffeoyl quinic acid, 3,4-dicaffeoyl quinic acid, 3,5-dicaffeoyl quinic acid and 4,5-dicaffeoyl quinic acid in beagle plasma. The quantitative HPLC-MS/MS method was applied to quantify these six major caffeoyl quinic acids in beagle plasma after the subcutaneous administration of Kaliziri injection. All of the six analytes reached their peak plasma of concentrations within 30 min.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Anchusa italica Retz. (Boraginaceae) is an important medicinal plant for the treatment of meningitis and pneumonia in traditional Uygur medicines. AIM OF THE STUDY To clarify the anti-inflammatory activity of A. italica, to reveal its molecular mechanisms, and to discover the anti-inflammatory active ingredients. MATERIALS AND METHODS Dried and crushed aerial parts of A. italica were extracted with 75% ethanol to yield crude extract (AICE) and AICE was fractionated to obtain petroleum ether extract (AIPE), dichloromethane extract (AIDE), ethyl acetate extract (AIEE), n-butanol extract (AIBE) and residues (AIW). By measuring the effects of AIPE, AIDE, AIEE, AIBE and AIW on cell viability and nitric oxide (NO) in Lipopolysaccharide (LPS) stimulated RAW264.7 cell lines, AIDE with the lowest cytotoxicity and NO contents was finally selected for further chemical and anti-inflammatory investigations. LC-MS/MS experiment was applied to analyze the chemical composition of AIDE. MTT and Griess methods were used to detect the cell viability and to quantify the nitrite levels in culture supernatants, respectively. Prostaglandin E2 (PGE2), interleukin-6 (IL-6), interleukin-1β (IL-1β) and tumor necrosis factor α (TNF-α) production was examined by ELISA assays. Real-time quantitative PCR was used to detect the expression of hemeoxygenase-1 (HO-1), Nrf2-mediated quinone oxidoreductase 1 (NQO-1), glutathione S-transferase A 1 (GSTA1) and glutathione S-transferase M 1 (GSTM1) mRNA. Western blot analysis was employed to examine the protein expression and enzymatic activities. RESULTS In preliminary anti-inflammatory screening, AIDE showed the lowest cytotoxicity and the most significant inhibitory effect on the production of NO (the inhibitory is 89%) induced by LPS among the tested five extracts. Thirty-three compounds including twenty-five triterpenoids were identified by LC-MS/MS analysis. AIDE could inhibit LPS-induced the over-expression of NO, IL-6, PGE2, IL-1β and TNF-α and down-regulate the levels of extracellular signal-regulated protein kinase (ERK), c-Jun N-terminal kinase (JNK), P38-MAPK (P38) and nuclear transcription factors κB-P65 (P65) phosphorylation. It promoted the mRNA expression level of HO-1, NQO-1, GSTA1 and GSTM1 and the protein expression level of nuclear factor erythroid 2-related factor 2 (Nrf2) and HO-1. After the treatment of AIDE, P65 nuclear translocation was inhibited and Nrf2 nuclear translocation was increased. In addition, the protein expression of pyrolytic relevant protein nod-like receptor family pyrin domain-containing 3 (NLRP3) and IL-1β were decreased after the AIDE treatment. CONCLUSIONS Anchusa italica Retz. exerted its anti-inflammatory activity by inhibiting the mitogen-activated protein kinase (MAPK), nuclear transcription factors κB (NF-κB) and pyrolytic relevant proteins, down-regulating inflammatory factor levels, and activating the Nrf2/HO-1 pathway. Triterpenoids might be its major active anti-inflammatory ingredients.

Abstract
Objective: To explore the application value of plasma heterogeneous nuclear ribonucleoprotein A2/B1(hnRNP A2B1), β-amyloid 42(Aβ42) and phosphorylated tau protein(P-tau) levels in elderly patients in the preoperative diagnosis of mild cognitive impairment(MCI). Methods: A total of 200 patients who underwent elective surgery at Tianjin Third Central Hospital from June 2020 to March 2021were Enrolled, regardless of gender, age 65-80 years old. According to the international MCI working group standards and the European Alzheimer's Disease Federation working group standards, patients were divided into MCI group and control group. There were 58 males and 42 females in each group. The patient's plasma hnRNP A2/B1, Aβ42 and P-tau levels were detected before operation. The sensitivity, specificity and accuracy of the diagnosis of MCI were calculated. The receiver operating characteristic curve were drew to evaluate the diagnostic value of each index. Results: The plasma levels of hnRNP A2/B1, Aβ42 and P-tau in the MCI group were 310.0 (275.1, 344.2), 34.5 (24.9, 42.5), 190.4 (150.4, 301.7) ng/L, respectively, which were significantly higher than those of the control group [272.7 (239.6, 291.5), 18.7 (14.7, 26.6), 140.0 (101.8, 217.5) ng/L]. The differences were statistically significant (all P<0.05). Taking the international MCI working group standard as the gold standard, the sensitivity, specificity and area under the ROC curve (AUC) of plasma hnRNP A2/B1 for predicting MCI were 80%, 61%, and 0.781, respectively. The sensitivity, specificity and AUC of plasma Aβ42 for predicting MCI were 78%, 73%, and 0.744. The sensitivity, specificity, and AUC of P-tau for predicting MCI were 51%, 79%, and 0.675, respectively. The sensitivity, specificity and AUC of hnRNP A2/B1 and Aβ42 in predicting MCI were not statistically significant (all P>0.05), but the sensitivity of both were higher than P-tau (all P<0.001). Compared with P-tau, the AUC of plasma hnRNP A2/B1 was higher when predicting MCI (P<0.05). When the three indicators were combined, the sensitivity was 82%, and the AUC was 0.842, both of which were the highest, but the specificity reduced (71%) (all P<0.05). Conclusions: Plasma hnRNP A2/B1 combined with Aβ42 and P-tau levels can improve the sensitivity and accuracy of MCI diagnosis in elderly MCI patients before surgery, and have the greatest diagnostic efficiency. It has certain application value.

Abstract
Alhagi pseudalhagi Desv. Extract (APE) is the major active fraction extracted from the aerial part of Alhagi pseudalhagi Desv. In view of its application in Uyghur medicine, it may be beneficial for the treatment of ulcerative colitis (UC). The aim of the present study was to investigate the possible beneficial effects of APE on UC mice and detect the possible mechanisms underlying these effects. Methods: An acute UC model was established in mice using dextran sulfate sodium. Sixty mice were randomly divided into six groups: normal, UC model, sulfasalazine (200 mg/kg), high-dose APE (APE-H, 2.82 g/kg), middle-dose APE (APE-M, 1.41 g/kg), and low-dose APE (APE-L, 0.70 g/kg) groups. Drugs were administered by gavage for 10 days after the induction of colitis. Serum and colon tissue samples were collected from the mice during the experiment, and survival signs, body weight changes, disease activity index (DAI), colon length, and colon wet weight in mice were determined after the treatment. UC-induced damage, including inflammation and ulceration of colon mucosa, were observed by the naked eye as well as using hematoxylin and eosin staining (H&E) and scanning electron microscopy and scored according to Wallace and Keean’s criteria. We measured the levels of tumor necrosis factor α (TNF-α), interleukin (IL)-1β, IL-6, and IL-10 in the serum and colon tissues using ELISA. Additionally, the relative protein levels of toll-like receptor 4 (TLR4), nuclear factor-kappa B p65 (NF-κB p65), phosphorylated NF-κB p65 at Ser536 (p-p65 Ser536), inhibitor kappa B-kinase ß (IK-Kβ), and phosphorylated IK-Kβ (Ser176/180) (p-IK-Kβ) in colonic mucosal epithelial tissues were detected using western blotting. The main functional components of APE were analyzed and confirmed by UPLC-MS/MS. Results: APE treatment repaired the UC-induced colon mucosa injury, reduced the weight loss, attenuated DAI, colon macroscopic damage index, and histological inflammation, and significantly downregulated the levels of inflammatory markers, including TNF-α, IL-1β, and IL-6, in the serum and colon tissues. Additionally, APE treatment reduced the levels of TLR4 and phosphorylation of p-NF-κB and p-IK-Kβ. The main components of APE are taxifolin, 3,5-dihydroxy-2-(4-hydroxyphenyl)-7-[(2R,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl) oxan-2-yl] oxychromen-4-one, hyperoside, rutin, kaempferol, isorhamnetin, 7,8-dihydroxyflavone, and kaempferide. Conclusions: To the best of our knowledge, the present study is first to demonstrate that APE exerts a protective effect against intestinal inflammation in UC by affecting TLR4-dependent NF-κB signaling pathways.

Abstract
Hyssopus cuspidatus is a famous spice and an aromatic vegetable. Few information could be available concerning its non-volatile chemical composition and bioactivities. Preliminary bioactive evaluations on the crude ethanol extract and its four fractions disclosed that the ethyl acetate fraction (EAF) exhibited antioxidant and antimicrobial bioactivities. LC-MS/MS analysis of EAF helped to identify sixty-four compounds, and phenolic compounds were the dominant components. Systematic separation and purification of EAF led to the isolation of thirty-four compounds. Six compounds were identified to be new and eighteen compounds were discovered from H. cuspidatus for the first time. Rosmarinic acid, methyl rosmarinate, butyl rosmarinate and salvigenin were the major components of EAF and their contents were determined. Most of isolated compounds exhibited significant or moderate antioxidant and antimicrobial activities. This research supported the edible application of H. cuspidatus and disclosed the potency of it as a natural antioxidant and antimicrobial food additive.

Abstract
Objectives: To evaluate the effect of a musculoskeletal ultrasound programme (MUSP) applying real-time ultrasonography with reinforcement of findings by a rheumatologist on improving disease-modifying anti-rheumatic drugs (DMARDs) adherence in rheumatoid arthritis (RA).Method: Eligible RA patients with low adherence score (< 6) on the 8-item Morisky Medication Adherence Scale (MMAS-8) were randomized to either an intervention group (receiving MUSP at baseline) or a control group (no MUSP), and followed up for 6 months. Adherence measures (patient-reported and pharmacy dispensing records) and clinical efficacy data were collected. The MUSP's feasibility and acceptability were assessed.Results: Among 132 recruited RA patients, six without baseline visits were excluded; therefore, 126 patients were analysed (62 intervention and 64 control). The primary outcome (proportion of patients with 1 month MMAS-8 score < 6) was significantly smaller (p = 0.019) in the intervention (35.48%) than the control group (56.25%). However, 3 and 6 month adherence and clinical efficacy outcomes were not significantly different between the two groups (all p > 0.05). All 62 patients completed the MUSP (mean time taken, 9.2 min), with the majority reporting moderately/very much improved understanding of their joint condition (71%) and the importance of regularly taking their RA medication(s) (79%). Most patients (90.3%) would recommend the MUSP to another RA patient.Conclusions: The MUSP improved RA patients' DMARDs adherence in the short term and was feasible and well accepted by patients. Future studies could evaluate whether repeated feedback using MUSP could help to sustain the improvement in DMARD adherence in RA patients, and whether this may be clinically impactful and cost-effective.

Abstract
Background:To facilitate earlier diagnosis of spondyloarthritis (SpA), we have previously cross-culturally adapted a self-administered screening questionnaire.Objectives:We aimed to improve the sensitivity of this questionnaire as a screening tool by comparing various scoring methods.Methods:Subjects newly referred to a rheumatology clinic self-administered the questionnaire before seeing a rheumatologist. Identification of axial SpA by the questionnaire using original scoring (Method A) and scoring based on Assessment of SpondyloArthritis International Society (ASAS) inflammatory back pain (IBP) criteria (Method B), ASAS referral criteria (Method C), ASAS classification criteria (Method D) and a combination of ASAS referral and classification criteria (Method E) were compared to classification by the ASAS classification criteria and diagnosis by rheumatologist. Since Methods B-E were based on SpA features, we compared self-reported vs rheumatologist-documented features in subjects with axial SpA.Results:Of 1418 subjects (age: 54 ± 14 years, female: 73%), 39 were classified as axial SpA cases by classification criteria. Methods A-E yielded sensitivities of 39%, 72%, 67%, 49% and 85%, respectively, among patients newly referred to the rheumatology clinic (Table 1). Rheumatologist-documented clinical SpA features exceeded self-report for IBP (62 vs 44%) and uveitis (15 vs 5%). The reverse was true for arthritis (21 vs 80%), enthesitis (28 vs 33%), dactylitis (3 vs 18%), good response to NSAIDs (33 vs 41%) and family history for SpA (5 vs 10%).Table 1.Performance of the five scoring methods for the cross-culturally adapted Hamilton axial SpA questionnaire.Scoring methodSensitivity(95% confidence interval)Specificity(95% confidence interval)Positive predictive value(95% confidence interval)Negative predictive value(95% confidence interval)Method A38.5(23.4 – 55.4)93.7(92.3 – 94.9)14.7(8.5 – 23.1)98.2(97.3 – 98.8)Method B71.8(55.1 – 85.0)73.1(70.7 – 75.4)7.0(4.7 – 10.0)98.9(98.1 – 99.5)Method C66.7(49.8 – 80.9)77.8(75.5 – 80.0)7.8(5.2 – 11.3)98.8(98.0 – 99.4)Method D48.7(32.4 – 65.2)74.9(72.5 – 77.2)5.2(3.2 – 8.0)98.1(97.1 – 98.8)Method E84.6(69.5 – 94.1)37.2(34.6 – 39.8)3.7(2.5 – 5.1)98.8(97.5 – 99.6)Method A: the original scoring defined by the questionnaire developers; Method B: a scoring based on the ASAS IBP criteria; Method C: a scoring based on the ASAS referral criteria; Method D: a scoring based on the ASAS classification criteria for axial and peripheral SpA; Method E: a scoring based on a combination of the ASAS referral and classification criteria.Conclusion:A self-administered questionnaire scored based on a combination of ASAS referral and classification criteria achieved high sensitivity in identifying axial SpA in subjects referred to a rheumatology clinic.

Abstract
Nine undescribed lignanamides, limoniumins A-I, together with ten known lignanamides and two known phenolics were isolated from ethyl acetate extract of the roots of Limonium gmelinii (Plumbaginaceae). Their structures were determined by spectroscopic analysis including 1D and 2D NMR and HRESIMS experiments. Limoniumin A is the first hybrid lignanamide of phenylpropanoid and coumarin. All tested lignanamides showed significant inhibitory activity against α-glucosidase stronger than positive control and remarkable inhibitory effect to PTP1B with IC50 values less than 10 μM. In addition, some lignanamides exhibited moderate cytotoxic activity against HeLa and MCF-7 cells and anti-inflammatory activity against COX-2 in a dose-dependent way.

Abstract
INTRODUCTION Chronic hepatitis B (CHB) remains common in endemic regions, causing significant healthcare burden. Patients with CHB may need to be adherent to nucleoside analogue (NA) for a long period of time to prevent complications. This study aims to investigate the safety, efficacy and patient experience of a virtual monitoring clinic (VMC) in monitoring stable patients taking NA for CHB. METHODS Patients on NA and regular follow-up were randomised to either VMC alternating with doctors' clinic visit or to a control group in which they continued standard follow-up by doctors. Therapy adherence was measured by medication possession ratio (MPR) for NA therapy, incidence of virological breakthrough and hepatocellular carcinoma (HCC) development at two years of follow-up. Patient acceptance was measured on a Likert scale of 1-10. RESULTS A total 192 patients completed follow-up: 94 and 98 patients in the VMC and control groups, respectively. Mean age was 60.6 ± 10.8 years, with 95.3% Chinese ethnicity and 64.1% males. Age, gender, race, educational, employment and financial status were similar in both groups. Upon study completion, the majority of patients - 76 (80.9%) in VMC group and 74 (75.5%) in control group - had MPR ≥0.8; 88.8% were satisfied and rated VMC better than a traditional follow-up clinic with doctors only. More than 85% of patients rated ≥8/10 on the Likert scale for VMC, and preferred VMC over traditional clinic visits. Clinical outcomes observed were HCC development in one (1.1%) in the VMC group and four (4.1%) in the control group (p = 0.369). Two (2.1%) and one (1.0%) virological breakthroughs were observed in the VMC and control groups, respectively (p = 0.615). No incidence of HCC or abnormal blood tests were missed in the VMC arm. DISCUSSION VMC is a viable and safe clinical model for monitoring stable CHB patients on NA therapy without compromising patients' adherence to medications and is preferred by patients.

Abstract
In this study, an iron-doped metal-organic framework (MOF) Fe/ZIF-8 was synthesized from ZIF-8 at room temperature. Direct carbonization of Fe/ZIF-8 under a nitrogen atmosphere produced nanoporous nitrogen doped carbon nanoparticles decorated with Fe component (Fe/NC). The Fe/NC exhibited a large surface area (1221.185 m2 g-1) and narrow pore-size distribution (3-5 nm). The nanoporous Fe/NC components along with Nafion were used to modify a glassy carbon electrode for the electrochemical determination of chloramphenicol and metronidazole via linear sweep voltammetry. Under optimal conditions, the reduction peak currents (observed at -0.237 V and -0.071 V vs. Ag/AgCl) of these analytes increased linearly with increasing chloramphenicol and metronidazole concentrations in the range of 0.1-100 μM and 0.5-30 μM, with the detection limits estimated to be 31 nM and 165 nM, respectively. This result was attributed to the large surface area, porous structure, high nitrogen content, and as well as the electrocatalytic effect of Fe atoms embeded in the carbon support. The proposed sensor was used for chloramphenicol and metronidazole analysis in samples, providing satisfactory results.

Abstract
BACKGROUND Dry skin is a common skin condition caused by reduction of water-holding capacity, which is regulated by skin barrier function. Dry skin can also be a symptom that indicates a more serious diagnosis. There are a number of moisturizers on the market, which play an important role in dermatologic and cosmetic therapies. However, the demand for these products with good and therapeutic efficiency is still growing. AIMS It remains necessary to investigate the effects of Elaeagnus L gum polysaccharides (EAP), which are prepared from gum of Elaeagnus angustifolia L. on the epidermal permeability barrier function and their possible underlying mechanisms. PATIENTS/METHODS EAP were purified, analyzed, and tested on human keratinocyte cell line (HaCaT) and then on the skin in vivo to evaluate their antiinflammatory activities and their impacts on impaired skin barrier function. RESULTS Histological analyses revealed that topical administration with EAP effectively attenuated dryness-like skin condition, including less percutaneous water loss rate, less infiltrate inflammation cells, and less epidermal thickening. Moreover, EAP inhibited the production of various inflammatory mediators and increased AQP-3, FLG, and LOR expression. CONCLUSION Our results indicated that EAP enhances epidermal permeability barrier function, and they can be used as a promising adjuvant agent in skin care cosmetics and in treating some skin disorders characterized by cutaneous inflammation and abnormal barrier function.

Abstract
OBJECTIVE Asthma is a chronic immune disease that has become a serious public health problem. The currently available medications are not ideal because of their limitations and side effects; hence, new target proteins and signaling cascades for precise and safe therapy treatment are needed. This work established an ovalbumin-induced asthma rat model and treated it with total flavonoid extract from the Xinjiang chamomile. The proteins that were differentially expressed in the chamomile extract-treated asthmatic rats and the asthma and healthy rat groups were identified using isobaric tagging followed by LC-MS/MS. Kyoto encyclopedia of genes and genomes pathway analysis of the differentially expressed proteins was performed. RESULTS Pathways involved in purine metabolism, herpes simplex infection, and JNK phosphorylation and activation mediated by activated human TAK1 were enriched, indicating the intrinsic links between the mechanism of asthma development and treatment effects. Furthermore, we constructed a protein-protein interaction network and identified KIF3A as a potential target protein of chamomile extract that affected the Hedgehog signaling pathway. CONCLUSIONS This study may provide new insights into the pathogenesis of asthma and reveal several proteins and pathways that could be exploited to develop novel treatment approaches.

Abstract
BACKGROUND The purpose of this study was to explore the correlation of anxiety and depression with therapeutic response to etanercept in psoriasis patients. PATIENTS AND METHODS One hundred and thirty-three patients with moderate-to-severe plaque psoriasis undergoing etanercept treatment were consecutively enrolled in this prospective cohort study, with all patients receiving etanercept treatment for 6 months. Psoriasis Area and Severity Index (PASI) score was evaluated at baseline (M0) and at month 1 (M1), M3 and M6 after treatment, and PASI 75/90 responses were calculated. The Hospital Anxiety and Depression Scale-Anxiety (HADS-A) score and the HADS-Depression (HADS-D) score were used to evaluate patients' anxiety and depression at M0, M1, M3 and M6. Sustained anxiety/depression were defined as HADS-A/D score≥8points both at M0 and M1. RESULTS Female gender and higher PASI score were associated with high risk of anxiety, while female gender, higher PASI score and longer disease duration were correlated with increased depression risk. After 6 months of etanercept treatment, 65.4% and 36.1% patients achieved PASI 75 and PASI 90 responses respectively, and both HADS-A and HADS-D scores were decreased. Most importantly, no correlation of baseline anxiety and depression with PASI 75 or PASI 90 response after 6 months of treatment was noted, while sustained depression, though not sustained anxiety, was observed to be correlated with decreased PASI 75 and PASI 90 responses. CONCLUSIONS Etanercept reduces anxiety and depression in psoriasis patients, and sustained depression correlates with reduced therapeutic response to etanercept.

Abstract
Empty follicle syndrome (EFS) is a disorder associated with female infertility and presents as a complete failure to retrieve oocytes during ART cycles despite normal follicle development and careful aspiration. To date, only two EFS cases have been reported with homozygous missense mutations in the luteinizing hormone/chorionic gonadotropin receptor (LHCGR) gene, and both cases showed normal estradiol (E2) production during ovulation induction. The molecular genetic mechanisms of EFS remain unknown. Herein, we report two novel homozygous inactivating LHCGR mutations, c.736 C>T (p.Q246*) and c.846dupT (p.R283*), in two female EFS patients from unrelated consanguineous families. The probands had impaired E2 production during the ART process, which differs from previously reported EFS cases. The inactivating mutations not only led to EFS in the two female probands, but also resulted in 46, XY disorder of sex development (46, XY DSD) in their male siblings. As far as we know, this is the first report of LHCGR mutations leading to both EFS and 46, XY DSD within the same pedigree. Our findings provide researchers and clinicians with a better understanding of phenotype-genotype correlations between EFS and 46, XY DSD and the LHCGR gene.

Abstract
This study was designed to investigate the mechanism of polyphenol-enriched extract of Rosa rugosa Thunb (RPE) in the control of dyslipidemia in diabetic rats. RPE was tested at three dosages (37.5 mg/kg, 75 mg/kg and 150 mg/kg) in the rat dyslipidemia model established with high fat diet feeding in combination with STZ injection (30 mg/kg). The RPE effect was evaluated after 4 weeks of treatment. In the RPE-treated rats, hepatic total cholesterol (TC) and triglyceride (TG) were significantly reduced, lipoprotein lipase (LPL) and liver lipase (HL) were significantly increased. The levels of alanine transaminase (ALT) and aspartate transaminase (AST) were decreased in the serum. Those effects of RPE were observed primarily at the mediate and high dosages. Expression of FGF21 was increased in the liver tissue and hepatic cell line 1c1c7 by RPE. The signals of p-AMPK, p-ACC, ACC, p-SIRT, and PGC-1α were significantly induced in the liver by RPE. The results suggest that RPE may improve hepatic steatosis and liver function by induction of AMPK signaling activity in the control of dyslipidemia.

Abstract
Type 2 diabetes mellitus (T2DM) is the most common type of diabetes with more than hundreds of millions of patients worldwide. However, the medicines for treatment of T2DM are very limited. In China, Punica granatum L. flower (PGF) has been used as an anti-diabetic herb in the herbal medicine. The activity involves in improvement of insulin sensitivity. However, the underlying mechanism of action is elusive. The current study was designed to address this issue by investigating the effect of polyphenols extract of PGF in diabetic rats. A rat model was orally administrated with PGF polyphenols extract at doses of 50 and 100 mg/kg for 4 weeks. Insulin sensitivity was improved as indicated by oral glucose tolerance test (OGTT), insulin tolerance test (ITT) and homeostasis model assessment of insulin resistance (HOMA-IR). At the molecular level, insulin signaling activity was improved with an elevation in insulin-stimulated phosphorylation of insulin receptor substrate (IRS-1), Akt and GSK-3β. Endoplasmic reticulum (ER) stress signals including phosphorylation of inositol-requiring kinase1 (IRE1) and activation of X box binding protein (XBP-1) splicing were decreased by the PGF treatment. Expressions of IRE1α, XBPs, and CHOP were all decreased by PGF. Blood lipid profile, liver glycogen content and antioxidant status were improved by PGF in the rats. The observations suggest that PGF is able to lower glucose levels in T2DM rats by improving the insulin resistance. The mechanism is likely related to the activation of Akt-GSK3β signaling pathway and inhibition of ER stress.

Abstract
OBJECTIVE The aims of the current study were to assess the prevalence of overweight and obesity by four different references and to explore the characteristics of adolescent overweight and obesity in Chinese secondary school students aged 12-18 years. STUDY DESIGN A cross-sectional study was conducted in this study. METHODS Using stratified random cluster sampling, 8999 secondary school students were enrolled. The references developed by Must and Dallal and Dietz, the Childhood Obesity Working Group of the International Obesity Task Force, the US Centers for Disease Control and Prevention, and the Group of China Obesity Task Force (GCOTF reference) were used to identify overweight and obese students. RESULTS The prevalence of adolescent overweight and obesity vary substantially based on the four references. The prevalence of adolescent overweight and obesity based on GCOTF reference are 8.4% and 4.1%, respectively, which is significantly lower than the prevalence of overweight and obesity in their peers in 2000 (χ2 = 24.03, P < 0.01). The prevalence of overweight and obesity in boys are 12.0% and 5.7%, which are higher than those in girls, 4.6% and 5.7% (χ2 = 240.68, P < 0.01). The prevalence of overweight and obesity in singletons are higher than those in non-singletons (χ2 = 40.25, P < 0.01). The prevalence of overweight and obesity in students with lower school community ladder of subjective social status are higher than those from higher ones (χ2 = 21.61, P < 0.01). CONCLUSION The GCOTF reference is more suitable for screening overweight and obesity in Chinese adolescents. The current prevalence rates of adolescent overweight and obesity decreased, and girls made a tremendous contribution to this decreasing trend. Singletons and adolescents in lower school community ladder of subjective socio-economic status may be at higher risk of getting overweight and obesity. More effective strategies with full consideration to the characteristics above should be developed to control and prevent adolescent overweight and obesity.

Abstract
Objective: To evaluate and explore the mechanism of the effect of hypertonic pre-injection on postoperative delirium in the aged. Methods: From June 2016 to February 2017, participants scheduled hip arthroplasty surgery were randomly divided into four groups: Group 1 (H1) 30 patients pre-injected 4 ml/kg hypertonic solution were proceeded general anesthesia; Group 2 (H2) 30 patients pre-injected 4 ml/kg hypertonic solution were proceeded spinal canal anesthesia; Group 3 (C1) 30 patients pre-injected 4 ml/kg isotonic saline were proceeded general anesthesia; Group 4 (C2) 30 patients pre-injected 4 ml/kg isotonic saline were proceeded spinal canal anesthesia in Department of Anesthesiology, Third Hospital of Hebei Medical University.All these patients were operated after anesthesia.To avoid electrolyte disorder, the level of Na(+) , Ca(2+) , K(+) in the artery blood was analyzed.Peripheral venous blood was extracted to detect the concentration of inflammatory factors IL-1β, IL-6, IL-10, TNF-α and nerve injury factor S100β.In order to evaluate the relationship of these inflammatory fators with monocyte, we used flow cytometry to detect the number of mononuclear in peripheral venous blood.After operation 1 to 3 days, all these patients were assessed cognitive function by Nu-DESC. Results: Electrolytes fluctuationed in the normal range in four groups at different time points.Compared with before infusion, IL-6, IL-1β and TNF-α of four groups were significantly increased in postoperative.Compared with group H(H1 or H2), IL-1β, IL-6 and TNF-α were increased and IL-10 was decreased in group C(C1 or C2) after the surgery.S100β of group C(C1 and C2) was higher than before infusion.No significant changes were found in the cotykines mentioned above between group H1 and H2. The expression of monocytes CD14(+) CD16(+) /CD14(+ +) was decreased and the incidence of postoperative delirium was lower in group H than group C(13.3%, 10.0% vs 33.3%, 36.7%, P<0.05). Conclusion: Hypertonic saline can improve postoperative delirium of the aged and the mechanism may be related to the inhibition of monocyte cells secreting inflammatory factors.

Abstract
AIM Adult growth hormone deficiency (AGHD) refers to decreased secretion of growth hormones in the adults, which is associated with increased clustering of conventional cardiovascular risk factors such as central obesity, insulin resistance and dyslipidemia. Metabolic syndrome (MetS), a recognized risk factor of cardiovascluar diseases, shares some clinical features. Given that the prevalence of MetS is on the rise in patients with AGHD, and that cardiovascular disease (CVD) is an important cause of morbidity and mortality in that population, the alternative, simple, non-invasive methods of assessing MetS among this population are needed. This study aims to determine the sensitivity of five anthropometric indices [Body mass index (BMI), Waist circumference (WC), Waist-to-hip ratio (WHR), Waist-to-height ratio (WHtR) and Visceral adiposity index (VAI)] in predicting metabolic syndrome in Chinese population-based patients with adult growth hormone deficiency. MATERIALS AND METHODS A total of 96 Chinese patients with adult growth hormone deficiency were included in this study. They were compared with equal number of apparently healthy persons with similar characteristics (matched with age and gender) to the previous group. Anthropometric measurements including weight, height, serum lipids indices, blood pressure (BP), fasting plasma glucose (FPG), WC were measured. BMI, WHR, WHtR, and VAI were calculated. RESULTS AND DISCUSSION AGHD patients with MetS had higher WC (91.00 ± 8.28 vs 78.01 ± 7.12), BMI (24.95 ± 2.91 VS 23.30 ± 2.80), WHR (0.92 ± 0.06 VS 0.87 ± 0.07), WHtR (0.53 ± 0.06 VS 0.47 ± 0.05), VAI [(5.59 (4.02, 7.55) VS 1.69 (0.87, 3.05)] levels in comparison to those without MetS. Meantime WC, BMI, WHR, WHtR, VAI was positively correlated to MetS components. ROC curve for participants with AGHD showed that VAI had the highest SS of 92% (BMI 0.812; WHR 0.706; WHtR 0.902; VAI 0.920, respectively) for prediction of MetS in AGHD. The optimal cutoff values for different adiposity markers in predicting MetS were as follows: WC (79.65), BMI (23.46); WHR (0.89); WHtR (0.54); VAI (2.29). CONCLUSION In conclusion, our study showed all adiposity measures of interest present themselves as easy and practical tools for use in population studies and clinical practice for evaluating MetS in AGDH and VAI was identified as the best in Chinese AGHD patients among them.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Rosa rugosa Thunb is a traditional Uygur medicine that has been used in the treatment of diabetes in Uygur ancient recipe for hundreds of years. However, the mechanism of Rosa rugosa Thunb activity is still unclear. This study was designed to address this issue by studying the polyphenols enriched extract (RPE) of Rosa rugosa Thunb in diabetic rats. MATERIALS AND METHODS RPE were tested in the inhibition of α-glucosidase and oxidative stress in vitro. RPE was administrated at dosages of 37.5, 75 and 150mg/kg body weight in the type 2 diabetic rats, which were made by high fat diet feeding plus a low dose of STZ injection (30mg/kg). The therapeutic effect was evaluated four weeks later. Oral glucose tolerance test (OGTT), insulin tolerance test (ITT) and insulin signal pathway (PI3K/AKT) were examined to determine insulin sensitivity. Blood glucose levels and body weight were measured weekly in the study. RESULTS In vitro, RPE exhibited an activity in the inhibition of α-glucosidase and had an excellent antioxidant activity in the liver of diabetic rats. RPE significantly decreased the fasting blood glucose, improved insulin sensitivity (HOMA-IR), OGTT, ITT and blood lipid profile. The glycogen synthesis and hexokinase activity were increased together with the improved signaling activity of insulin as indicated by p-IRS, p-IR, p-AKT, and p-GSK-3β. CONCLUSIONS The results suggest that RPE reduced blood glucose in type 2 diabetic rats by improvement of insulin sensitivity. The effect is likely achieved by inhibition of oxidative stress and α-glucosidase.

Abstract
Cotton plants accumulate phytotoxins, such as gossypol and related sesquiterpene aldehydes, to resist insect herbivores. The survival of insects exposed to toxic secondary metabolites depends on the detoxification metabolism mediated by limited groups of cytochrome P450. Gossypol has an antibiotic effect on Aphis gossypii, and as the concentrations of gossypol were increased in the present study, the mortality of cotton aphids increased from 4 to 28%. The fecundity of the cotton aphids exposed to gossypol was also significantly reduced compared with the control. The transcriptional levels of CYP6DA2 in cotton aphids were significantly induced when exposed to gossypol, and knockdown of the CYP6DA2 transcripts by RNA interference (RNAi) significantly increased the toxicity of gossypol to cotton aphids. To further understand the gossypol regulatory cascade, the 5'-flanking promoter sequences of CYP6DA2 were isolated with a genome walker, and the promoter was very active and was inducible by gossypol. Co-transfection of the cap 'n' collar isoform C (CncC) and CYP6DA2 promoters dramatically increased the expression of CYP6DA2, and suppression of the CncC transcripts by RNAi significantly decreased the expression levels of CYP6DA2, and significantly increased the toxicity of gossypol to cotton aphids. Thus, the transcriptional regulation of CYP6DA2 involved the transcriptional factor CncC.

Abstract
Phenotype is defined as the state of an organism resulting from interactions between genes, environment, disease, molecular mechanisms, and chance. The purpose of the emerging field of phenomics is to systematically determine and measure phenotypes across biology for the sake of understanding. Phenotypes can affect more than one cell type and life stage, so ideal phenotyping would include the state of every cell type within the context of both tissue architecture and the whole organism at each life stage. In medicine, high-resolution anatomic assessment of phenotype is obtained from histology. Histology's interpretative power, codified by Virchow as cellular pathology, is derived from its ability to discern diagnostic and characteristic cellular changes in diseased tissues. Cellular pathology is observed in every major human disease and relies on the ability of histology to detect cellular change in any cell type due to unbiased pan-cellular staining, even in optically opaque tissues. Our laboratory has shown that histology is far more sensitive than stereomicroscopy for detecting phenotypes in zebrafish mutants. Those studies have also shown that more complete sampling, greater consistency in sample orientation, and the inclusion of phenotypes extending over longer length scales would provide greater coverage of common phenotypes. We are developing technical approaches to achieve an ideal detection of cellular pathology using an improved form of X-ray microtomography that retains the strengths and addresses the weaknesses of histology as a screening tool. We are using zebrafish as a vertebrate model based on the overlaps between zebrafish and mammalian tissue architecture, and a body size small enough to allow whole-organism, volumetric imaging at cellular resolution. Automation of whole-organism phenotyping would greatly increase the value of phenomics. Potential societal benefits would include reduction in the cost of drug development, a reduction in the incidence of unexpected severe drug and environmental toxicity, and more rapid elucidation of the contributions of genes and the environment to phenotypes, including the validation of candidate disease alleles identified in population and personal genetics.
