ABSTRACT
The purpose of this study was to explore the improving effect of Anshen Dingzhi Prescription (ADP) on Alzheimer's disease (AD)-like behavior in mice and its mechanisms. The main chemical components of ADP were identified by ultra performance liquid chromatography-time-of-flight mass spectrometry (UPLC-Q-TOF-MS). The AD-like mouse model was induced by D-galactose (D-gal) combined with Aβ1-42 oligomer (AβO). The effect of ADP on AD-like behavior in mice was assessed using various behavioral experiments; pathomorphological changes in mouse hippocampal tissue were observed by Nissl staining and transmission electron microscopy; ELISA was used in the assessment of oxidative stress factors and inflammation-related factor levels; Western blot was performed to detect the expression of Aβ, Tau and glial fibrillary acidic protein (GFAP) proteins. The active components of ADP were screened according to TCMSP and HERB database, and the action targets of active components were predicted by Swiss Target Prediction platform. In addition, the targets of AD were predicted through DisGeNET database. Further, GO and KEGG enrichment analysis of common targets was carried out by Metascape database. Combined with the results of GO and KEGG analysis, in vivo experiments were carried out to explore the potential mechanism of ADP improving AD-like behavior in mice from the PI3K/Akt, calcium signal pathway and synaptic function. Finally, the core components of ADP were molecularly docked to the validated targets using Autodock Vina. Animal experiments were approved by the Animal Ethics Committee of Anhui University of Chinese Medicine (approval number: AHUCM-mouse-2021080). The results showed that the five chemical components, including ginsenoside Rg1, ginsenoside Rb1, tenuifolin, poricoic acid B and α-asarone were found in the ADP. ADP significantly improved the anxiety-like behavior and memory impairment, protected hippocampal neurons, decreased the levels of oxidative stress and inflammation, and inhibited the expression of Aβ and p-Tau induced by D-galactose combined with AβO in mice. The results of network pharmacology suggested that PI3K/Akt, calcium signal pathway and cell components related to postsynaptic membrane might be the key factors for ADP to improve AD. Animal experiments revealed that ADP up-regulated N-methyl-D-aspartate receptor 2A (GluN2A), postsynaptic density protein 95 (PSD95), calpain-1, phosphorylated protein kinase B (p-Akt), phosphorylated cAMP response element binding protein (p-CREB), brain-derived neurotrophic factor (BDNF) expression and inhibited p-GluN2B and calpain-2 expression in the hippocampus of AD-like mice. The molecular docking results demonstrated that the core components of ADP, such as panaxacol, dehydroeburicoic acid, deoxyharringtonine, etc. had a high binding ability with the validated targets GRIN2A, GRIN2B, PSD95, etc. In summary, our results indicate ADP improves AD-like pathological and behavioral changes induced by D-galactose combined with AβO in mice, and the mechanism might be related to the NMDAR/calpain axis and Akt/CREB/BDNF pathway.

Objective:To investigate the mechanism of Candida albicans Int1 in regulating septin organization. Methods:A series of full-length and truncated fragments of Int1 were constructed and fused with green fluorescent protein (GFP). The intracellular localization of the fusion proteins was observed under a fluorescence microscope. The region in Int1 that was required for bud neck localization was identified. Full-length and fragments of Int1 were overexpressed in the yeast Saccharomyces cerevisiae and the changes in cell growth, cell morphology and septin organization were investigated to determine the functional region in Int1 that mediated the interaction with septin. Moreover, the co-localization of the region and septin was analyzed. Results:The full-length Int1 consisted of 1 661 amino acid residues. A middle region of 209 amino acid residues, Int1-M4 (739-947 aa), that could be localized at the bud neck during both small and large bud periods was identified. Overexpression of Int1-M4 led to significant growth defects, elongated bud and disorganized septin. In the cells with elongated bud, Int1-M4 and septin with abnormal structures could be co-localized.Conclusions:Int1-M4 (739-947 aa), the middle region of Int1 containing 209 amino acid residues, mediated the bud neck localization and the interaction with septin, playing an important role in regulating septin organization.
ABSTRACT
Qi-Yu-San-Long decoction(QYSLD)is a traditional Chinese medicine that has been clinically used in the treatment of non-small-cell lung cancer(NSCLC)for more than 20 years.However,to date,metabolic-related studies on QYSLD have not been performed.In this study,a post-targeted screening strategy based on ultra-performance liquid chromatography coupled with quadrupole time-of-flight full infor-mation tandem mass spectrometry(UPLC-QTOF-MSE)was developed to identify QYSLD-related xeno-biotics in rat urine.The chemical compound database of QYSLD constituents was established from previous research,and metabolites related to these compounds were predicted in combination with their possible metabolic pathways.The metabolites were identified by extracted ion chromatograms using predicted m/z values as well as retention time,excimer ions,and fragmentation behavior.Overall,85 QYSLD-related xenobiotics(20 prototype compounds and 65 metabolites)were characterized from rat urine.The main metabolic reactions and elimination features of QYSLD included oxidation,reduction,decarboxylation,hydrolysis,demethylation,glucuronidation,sulfation,methylation,deglycosylation,acetylation,and associated combination reactions.Of the identified molecules,14 prototype compounds and 58 metabolites were slowly eliminated,thus accumulating in vivo over an extended period,while five prototypes and two metabolites were present in vivo for a short duration.Furthermore,one pro-totype and five metabolites underwent the process of"appearing-disappearing-reappearing"in vivo.Overall,the metabolic profile and characteristics of QYSLD in rat urine were determined,which is useful in elucidating the active components of the decoction in vivo,thus providing the basis for studying its mechanism of action.
ABSTRACT
Objective:To investigate the mechanism of PE_PGRS60 protein in the pathogenesis of Mycobacterium tuberculosis infection. Methods:The cloned and purified PE_PGRS60 protein from Mycobacterium tuberculosis was used to stimulate RAW264.7 cells. The expression of cyclooxygenase 2(COX2) mRNA and protein was detected by qRT-PCR and Western blot, respectively. The signal pathways that may regulate the expression of COX2 were screened, and the expression of inflammatory cytokines induced by PE_PGRS60 was detected by ELISA. The level of cell death was measured by lactate dehydrogenase(LDH) release test and flow cytometry PI staining. Western blot was used to detect the expression of COX2 in Peripheral blood mononuclear cell(PBMC) from active tuberculosis patients. Results:PE_PGRS60 protein was found to promote the expression of COX2 in RAW264.7 cells and activate the three major members of the mitogen-activated protein kinase(MAPK) family: extracellular regulated protein kinase(ERK), p38 and c-Jun N-terminal kinase(JNK). Interestingly, only JNK-IN-7, the inhibitor of JNK was observed to suppress the up-regulation expression of COX2 induced by PE_PGRS60. This up-regulated expression of COX2 was also found in PBMCs from active tuberculosis patients. The COX2 inhibitor celecoxib can effectively block the expression of the inflammatory factors IL-1β, TNF-α and IL-6 induced by PE_PGRS60 and promote macrophage death.Conclusions:PE_PGRS60 can promote macrophages to release inflammatory factors by activating JNK/COX2 signal axis. Some macrophages still die under the protection of COX2.
ABSTRACT
In this study, ultra-performance liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry(UPLC-Q-TOF-MS)-based liver metabolomics approach was used to explore the mechanism of "Trichosanthis Fructus-Allii Macrostemonis Bulbus" in improving atherosclerosis(AS) of mice with apolipoprotein E gene knockout(ApoE~(-/-)). AS mouse model was induced by high-fat diet. The pathological and biochemical indexes such as the histopathological changes, body weight, liver weight, blood lipid level and inflammatory factors in the liver of mice were determined. The metabolic profiling of mice liver samples was performed with UPLC-Q-TOF-MS. Multiple statistical analysis methods including partial least squares discriminant analysis(PLS-DA) and orthogonal partial least squares discriminant analysis(OPLS-DA) were employed to screen and identify biomarkers. The levels of related enzymes including LCAT, sPLA2, EPT1 and ACER1 were detected. The results showed that "Trichosanthis Fructus-Allii Macrostemonis Bulbus" significantly reduced the areas of aortic plaque and fat vacuoles of liver in AS mice and decreased the accumulation of lipid droplets and liver coefficient. "Trichosanthis Fructus-Allii Macrostemonis Bulbus" also regulated the levels of blood lipid and inflammatory injury in the liver. The metabolites of the control group, the model group and the "Trichosanthis Fructus-Allii Macrostemonis Bulbus" group could be distinguished significantly. Fifteen potential biomarkers related to AS were discovered and preliminarily identified, seven of which could be regulated by "Trichosanthis Fructus-Allii Macrostemonis Bulbus" in a trend of returning to normal. Metabolic pathway analysis screened out two major metabolic pathways. "Trichosanthis Fructus-Allii Macrostemonis Bulbus" obviously regulated the levels of LCAT, sPLA2, EPT1 and ACER1. It was inferred that "Trichosanthis Fructus-Allii Macrostemonis Bulbus" could play a major role in AS treatment by regulating glycerophospholipid and sphingolipid metabolism disorders in the liver, with the mechanism probably relating to the intervention of the expression of LCAT, sPLA2, EPT1 and ACER1.

ABSTRACT
Objective@#This study aimed to measure the basal energy expenditure (BEE) of Chinese healthy adults and establish an accurate predictive equation for this population.@*Methods@#In total, 470 Chinese healthy adults had their BEE measured using the Cosmed K4b portable metabolic system. Multiple linear regression analysis was applied to develop new optimal equations for predicting BEE. The bias, accuracy rate, concordance correlation coefficient (CCC), and root mean square error (RMSE) were used to evaluate the accuracy of the predictive equations.@*Results@#There was a significant difference in BEE between males and females, with 5,954 kJ/d and 5,089 kJ/d, respectively. People living in rural areas expended significantly higher BEE (5,885 kJ/d) than those in urban areas (5,279 kJ/d). Previous equations developed by Henry, Schofield, Harris-Benedict (H-B), and Liu overestimated the BEE of Chinese healthy adults. The new equations derived from the present study displayed the smallest average bias and RMSE from the measured basal energy expenditure (mBEE). The CCC of the new equations was higher than other predictive equations, but it was lower than 0.8. There was no significant difference in the accuracy rate among all predictive equations.@*Conclusions@#Sex and regional differences in BEE were observed in Chinese healthy adults. Neither the widely used previous predictive equations nor the one derived in the present study were accurate enough for estimating the BEE of Chinese healthy adults. Further study is required to develop more accurate equations for predicting the BEE of Chinese healthy adults aged between 20-45 years.

Gandou decoction (GDD), a well-known traditional Chinese medicine (TCM) formula, has been widely used for decades to treat Wilson's disease (WD) in China due to its remarkable clinical effects. However, the chemical constituents of GDD still remain unclear because of their complexity. In this work, a reliable and sensitive strategy based on ultra-performance liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry (UPLC-Q-TOF-MSE) and UNIFI informatics platform was applied to investigate the chemical components in GDD. In total, 96 compounds including anthraqui-nones, alkaloids, protostane triterpenoids, flavonoids, triterpenoid saponins, tannins, curcuminoids, etc, were identified or tentatively characterized from GDD by comparing their retention time, accurate mass within 5 ppm error and MSE fragmentation patterns. Among them, eleven compounds were confirmed unambiguously with reference standards. Representative compounds in different chemical structure types were analyzed in fragmentation patterns and characteristic ions. Moreover, to better understand the chemical contribution of individual herbs to the whole decoction, the corresponding each herb in GDD was also detected. This study developed a rapid method for characterizing the chemical constitu-ents in GDD, which could not only be used for chemical standardization and quality control, but also be helpful for further research of GDD in vivo.
ABSTRACT
Objective:To explore the morphology and vessel distribution of the scapholunate interosseous ligament and anatomical basis for the clinical reconstruction of scapholunate interosseous ligament.Methods:From October, 2018 to December, 2018, 12 fresh wrist joint specimens were perfused with gelatin-lead oxide solution from ulnar or radial artery and scanned under micro-CT. The morphology of scapholunate interosseous ligament in neutral position and the distribution of nutrient vessels in the ligament were observed on reconstructed 3D images by Mimics. The width, length and thickness of palmar, dorsal and proximal ligaments were measured. The anatomical parameters at the entrance of nutrient vessels in the scapholunate interosseous ligament were taken and their relationship with the blood supply to the scapholunate was analyzed.Results:①For scapholunate interosseous ligament, it was found that the average length of the proximal sub-region was the longest, the length of palmar and dorsal sides was similar to each other and the widest and thinnest was in palmar side, while the thickness and width of dorsal and proximal were similar. ②There was no nutrient vessel in the proximal part of the scapholunate interosseous ligament. But there were abundant nutrient vessels in the palmar and dorsal scapholunate interosseous ligament, and there was no significant difference in blood supply to palmar and dorsal scapholunate interosseous ligament ( P>0.05). ③The palmar and dorsal medial nutrient vessels that supply to the scapholunate interosseous ligament enter the scapholunate from the attachment of ligament of scapholunate interosseous joint. Conclusion:The palmar side of the scapholunate interosseous ligament is wider and thinner than that of the other subareas, which makes it more vulnerable to injury from an anatomical point of view. There is abundant blood supply to the palmar and dorsal subareas of the scapholunate interosseous ligament and the supplying vessels anastomose inside the scapholunate bone. There is no distribution of blood vessel at the proximal part of scapholunate interosseous ligament, hence is difficult to heal. An injury of palmar and dorsal ligaments may affect the blood supply of scapholunate.
ABSTRACT
To identify major bioactive components and metabolites of Gandou decoction (GDD) in urine of normal and copper-laden rats, an integrative approach that ultra-performance liquid chromatography quadrupole time-of-flight tandem mass spectrometry (UPLC-Q-TOF-MSE) coupled with xenometabolomics analytical platform was established. Mass spectral data information about retention time, accurate m/z and ionic strength of rat urine samples was performed under positive and negative ion modes. Unsupervised principal components analysis (PCA) and supervised orthogonal partial least-squared discriminant analysis (OPLS-DA) were used to reveal the differential ions. As a result, a total of 77 compounds including 45 prototypes and 32 metabolites in urine were detected. Results indicated that anthraquinones, alkaloids and tetracyclic triterpenoids and flavonoids were the main chemical components of GDD in rat urine; the main metabolic pathways of these compounds in rat urine mainly include hydroxyl, methylation, sulfating, glucuronidation, and so on. UPLC-QTOF-MSE coupled with xenometabolomics analytical platform is fast and efficient so that facilitates authentication of the material basis of Chinese herb compound in vivo, can also be used as an effective tool for ascertaining trace bioactive components in vivo. The animal experiments were approved by the Experimental Animal Ethics Committee of Anhui University of Chinese Medicine (No. 2019025).
ABSTRACT
Objective:To explore the correlation and characteristics of Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA) and Rivermead Behavioural Memory Test-III (RBMT-III) in evaluating memory ability of patients with brain injuries. Methods:From March, 2016 to February, 2018, 62 patients with brain injuries were evaluated with the Chinese version of MMSE, MoCA and RBMT-III. The correlation among them was analyzed. Results:There was positive correlation among the total scores of MMSE, MoCA and RBMT-III (r = 0.682 to 0.786, P < 0.001), as well as the retrospective memory (r = 0.525 to 0.610, P < 0.001) and long-term memory (r = 0.553 to 0.692, P < 0.001). There was positive correlation between RBMT-III and MMSE in short-term memory (r = 0.337, P = 0.007). The prospective memory of RBMT-III positively correlated with retrospective memory of MMSE and MoCA (r = 0.639, r = 0.585, P < 0.001), and the short-term memory of RBMT-III with long-term memory of MMSE and MoCA (r = 0.454, r = 0.534, P < 0.001). Conclusion:MMSE, MoCA and RBMT-III are consistent in evaluating retrospective memory and long-term memory for patients with brain injuries. RBMT-III and MMSE are consistent in evaluating short-term memory for patients with brain injuries. The memory scores of MMSE and MoCA are helpful to judge the event-based prospective memory in patients with brain injuries, while the scores of long-term memory are helpful to judge short-term memory.
ABSTRACT
Databases including China Biological Medicine database(CBM), Chinese scientific journals full-text database(VIP), China National Knowledge Infrastructure database(CNKI), WanFang Data, PubMed, and EMbase were searched from inception to March 2018 to collect the randomized controlled trials(RCTs) on Shenqi Fuzheng Injection combined with chemotherapy for the treatment of breast cancer. All included studies were critically appraised by two independent reviewers by following the cochrane systematic review method and using Revman 5.3 software and State 12.0 for data analysis. After screening, 20 RCTs involving 2 095 patients were included in the study. Meta-analysis showed that as compared with control group of chemotherapy alone, Shenqi Fuzheng Injection combined with chemotherapy could improve the clinical curative efficiency, the KPS score, and immune function indexes such as total T cells, Th cells and Ts cells; inhibit the decline of white blood cells(WBC), platelets in blood system, T-lymphocyte subsets such as CD3~+, CD4~+, CD4~+/CD8~+, alleviate myelosuppression and reduce the incidence of side effects such as gastrointestinal adverse reaction, liver and kidney dysfunction and abnormal electrocardiogram. The results revealed that for clinical breast cancer patients, Shenqi Fuzheng Injection combined with chemotherapy could significantly improve its clinical efficacy and reduce adverse reactions. However, the conclusions still need to be verified by high-quality, multi-center, large-sample, prospective, randomized and double-blind clinical trials. In conclusion, this study has systemically evaluated the efficacy and safety of Shenqi Fuzheng Injection combined with chemotherapy in treatment of breast cancer and provided the reference of evidence-based medicine for safe and effective clinical application of medicines.

ABSTRACT
To systemically evaluate the therapeutic efficacy and safety of Danshen Chuanxiongqin Injection in treatment of acute cerebral infarction and provide the reference of evidence-based medicine for its clinical safety and effective drug use. Databases including CNKI, WanFang Data, SinoMed, the Cochrane Library, EMbase and PubMed were searched from inception to April 2018 to collect the randomized controlled trials (RCTs) on Danshen Chuanxiongqin Injection in the treatment of acute cerebral infarction. The quality of all included studies was evaluated by two independent reviewers following the cochrane systematic review method and using Revman5.3 software and State13.0 for Meta-analysis. A total of 30 RCTs involving 3 233 patients with acute cerebral infarction were included in the study after literature quality evaluation. Meta-analysis showed that as compared with the control group of conventional western medicine alone, Danshen Chuanxiongqin Injection combined with conventional western medicine can achieve better efficacy in treatment of acute cerebral infarction, increase the clinical total effective rate (RR=1.22, 95% CI [1.18, 1.27], <0.000 01) and activities of daily living (MD=9.42, 95% CI [8.12, 10.72], <0.000 01), and improve the degree of neurological impairment (MD=-3.99, 95% CI [-4.89, -3.07], <0.000 01). Furthermore, the result showed that Danshen Chuanxiongqin Injection in the treatment of acute cerebral infarction can significantly decrease the whole blood high-shear viscosity, whole blood low-shear viscosity, plasma viscosity, fibrinogen level and other hemorheological indexes (<0.01). This Meta-analysis demonstrated that Danshen Chuan xiongqin injection in the treatment of acute cerebral infarction is safe and effective, but lacks the large multicenter clinical randomized trials to support the treatment outcome.
