【Objective】 To investigate the feasibility of leucocyte-reduced pooled platelet concentrates from whole blood stored at 4℃, and provide theoretical basis for the components preparation. 【Methods】 The collected 400 mL ACD-B anticoagulant whole blood was randomly divided into two groups, stored at 4℃ and room temperature. The buffy coat was prepared within 6 hours and store at 22℃ until next day to prepare leucocyte-reduced pooled platelet concentrates. Platelet samples on day 1, 3, 5 and 7 were taken for the blood cell count and related parameter detection. The pH, glucose and lactic acid content were determined to reflect the metabolic status, and the thromboelastography, platelet aggregation rate and PAC-1 and CD62P expression were determined to reflect the function and activation of platelets. The difference in platelets between two groups were analyzed. 【Results】 With the extension of storage time, the count of leucocyte-reduced pooled platelet concentrates decreased gradually, but the platelets distribution width (PDW), mean platelet volume (MPV) and platelet-larger cell ratio (P-LCR) increased gradually in two groups, with no statistical significance (P>0.05).The pH and glucose contents in two groups gradually decreased, but the lactic acid content gradually increased, with no significant difference (P>0.05). The thrombelastogram showed MA value that reflecting platelet function has no significant change during the storage, and there was no significant difference between the two groups (P>0.05). The aggregation rates decreased while the expression of PAC-1 and CD62P increased gradually with the prolongation of preservation time, with no significant difference between the two groups (P>0.05). 【Conclusion】 There is no significant difference in platelet count, function and activation between whole blood stored at 4℃ and at room temperature within 6 hours. Whole blood stored at 4℃ within 6 hours can be considered as the raw material for leucocyte-reduced pooled platelet concentrates.

Acute lung injury (ALI), as a common clinical emergency, is pulmonary edema and diffuse lung infiltration caused by inflammation. The lack of non-invasive alert strategy, resulting in failure to carry out preventive treatment, means high mortality and poor prognosis. Stimulator of interferon genes (STING) is a key molecular biomarker of innate immunity in response to inflammation, but there is still a lack of STING-targeted strategy. In this study, a novel STING-targeted PET tracer, [18F]FBTA, was labeled with high radiochemical yield (79.7 ± 4.3%) and molar activity (32.5 ± 2.9 GBq/μmol). We confirmed that [18F]FBTA has a strong STING binding affinity (Kd = 26.86 ± 6.79 nmol/L) and can be used for PET imaging in ALI mice to alert early lung inflammation and to assess the efficacy of drug therapy. Our STING-targeted strategy also reveals that [18F]FBTA can trace ALI before reaching the computed tomography (CT) diagnostic criteria, and demonstrates its better specificity and distribution than [18F]fluorodeoxyglucose ([18F]FDG).

O-linked-N-acetylglucosamine (O-GlcNAc) modification is a unique post-translational modification that plays a regulatory role in many cellular processes, such as transcription, intracellular signaling, endocytosis, and protein stability. Epidermal growth factor (EGF) domain-specific O-GlcNAc transferase (EOGT) is an endoplasmic reticulum (ER) resident protein which can glycosylate the residues of Ser or Thr of secreted or membrane (transmembrane) glycoproteins containing EGF domain. Notch signaling pathway is involved in cell-to-cell communication which regulates cell biological processes through interactions between adjacent cells. To date, EOGT-mediated O-GlcNAc modification has been found to be involved in many human diseases, and shown significant relation with Notch signaling pathway. However, the specific molecular mechanisms have not been fully elucidated. In this review, we briefly introduce recent studies regarding to the roles of EOGT-mediated O-GlcNAc modification and its correlation with Notch signaling pathway in human diseases.

【Objective】 To investigate the feasibility of differentiation of human AB plasma hematopoietic stem/progenitor cells (HSCs/HPCs) from peripheral blood into mature erythrocytes. 【Methods】 Hematopoietic stem/progenitor cells were induced to be differentiated into mature erythrocytes in the medium supplemented with 5% FBS, 3% FBS + 2% human AB plasma and 8% human AB plasma, respectively, and inoculated in 24-well culture plate at the density of 1×106/mL. Cell proliferation and morphological changes were observed in three different groups. Flow cytometry was used to detect erythroid terminal differentiation markers, i. e. GPA, Band3 and α4(α4-integrin), and late erythroid cell enucleation in different group. The effects of different culture conditions on HSCs/HPCs differentiation into mature erythrocytes were compared. 【Results】 The cell growth and proliferation multiples of the three groups (8% human AB plasma, 5% FBS and 3% FBS+ 2% human AB plasma) were 2 573±116 vs 2 514±246 vs 2 539±119(P>0.05), respectively. The morphological changes of the three groups were similar. With the extension of culture time, the cells differentiated from proerythroblasts to basophils, polychromatic erythroblasts and positive erythroblasts, and almost all of them differentiated into erythrocytes enucleation on day 21. GPA expression and enucleation rate(%) of the three groups were 97.17±1.91 vs 94.95±1.61 vs 96.15±1.38, and 85.1±3.26 vs 86.93±5.96 vs 86.5±3.36(P>0.05), respectively. 【Conclusion】 The differentiation of HSCs/HPCs from peripheral blood plasma into mature erythrocytes from human AB was similar to that of fetal bovine serum.
摘要
The cross combination of dry-method(network pharmacology analysis) and wet-method(high-resolution mass spectro-metry with antioxidation experiment) was used to predict antioxidant quality markers(Q-markers) of Hippophae tibetana. Ultra-high performance liquid chromatography coupled with hybrid quadrupole-orbitrap mass spectrometry(UPLC-Q-Exactive Orbitrap-MS) was developed to rapidly separate and identify the chemical constituents in H. tibetana. Then in DPPH free radicals and superoxide anion scavenging experiment, the antioxidant activity of the four different polar parts with extracts of petroleumether, ethyl acetate, n-butanol and water was evaluated. Network pharmacology method was used for functional enrichment and pathway analysis to screen antioxidant-related components and preliminarily explain the mechanism of action. On this basis, multi-source information was integrated to predict the antioxidant Q-markers. The results showed that 51 components in H. tibetana were identified, including 18 flavonoids, 14 terpenoids, 6 alkaloids, 4 coumarins and phenylpropanoids, 3 volatile components and 2 polyphenols. The antioxidant capacity of different fractions: ethyl acetate > n-butanol > water > petroleum ether. The medicine mainly acted on PI3 K-Akt and FoxO signaling pathways to perform antioxidant effects through flavonoids such as quercetin, luteolin and kaempferol. According to the results of dry-method and wet-method, quercetin, luteolin and kaempferol, the representatives of poly-hydroxy flavone, may be the antioxidant Q-markers of H. tibetana. In this study, with the antioxidant Q-markers of H. tibetana as an example, an investigation model of predicting Q-marker was discussed based on the ternary system of composition, function and informatics, providing a scientific basis for the establishment of quality evaluation standards for H. tibetana.

The ventral part of the anteromedial thalamic nucleus (AMv) is in a position to convey information to the cortico-hippocampal-amygdalar circuit involved in the processing of fear memory. Corticotropin-releasing-factor (CRF) neurons are closely associated with the regulation of stress and fear. However, few studies have focused on the role of thalamic CRF neurons in fear memory. In the present study, using a conditioned fear paradigm in CRF transgenic mice, we found that the c-Fos protein in the AMv CRF neurons was significantly increased after cued fear expression. Chemogenetic activation of AMv CRF neurons enhanced cued fear expression, whereas inhibition had the opposite effect on the cued fear response. Moreover, chemogenetic manipulation of AMv CRF neurons did not affect fear acquisition or contextual fear expression. In addition, anterograde tracing of projections revealed that AMv CRF neurons project to wide areas of the cerebral cortex and the limbic system. These results uncover a critical role of AMv CRF neurons in the regulation of conditioned fear memory.

Non-alcoholic fatty liver disease (NAFLD) has become one of the most common chronic liver diseases worldwide, causing serious economic and medical burdens. Currently, Chinese medicine (CM) has become an important means in treating NAFLD in China. Intestinal microecology (IM) is an important part of the internal environment in the human body and is involved in the occurrence and development of NAFLD. In this paper, the authors systematically discuss the significance of IM in the pathogenesis of NAFLD and the current status of research on the CM treatment of NAFLD via IM regulation. In combination with our own research practice, we propose that IM is an important target for the treatment of NAFLD with CM and formulate plans for future research to target limitations existing in current studies.
摘要
The property of medicine is the "identity card" of traditional Chinese medicine (TCM), and the key to crack the theory of property of TCM. Based on molecular thermodynamics, the effects of interaction between TCM and organs in vitro were studied from the perspective of micro-energy release and absorption in order to construct a new idea of characterizing meridian theory. Scutellaria baicalensis, for example, application of isothermal titration calorimetry (ITC) were used to determine the energy changes during the interaction of Scutellaria baicalensis and its main active ingredient baicalin with brain, heart, lung, spleen and kidney in vitro, comparison including the association constant (Ka) and disassociation constant (Kd), combined with thermodynamic parameters, such as stoichiometry ratio (n), enthalpy change (ΔH), entropy change (ΔS), Gibbs free energy (ΔG), it is found that the interaction intensity between Scutellaria baicalensis and lung is significantly stronger than that of other organs, which is consistent with the theory of the return of Scutellaria baicalensis in ancient books. In addition, baicalin, the main active ingredient, showed the same action pattern as Scutellaria baicalensis. The thermodynamic parameters analysis showed that the action was a weak bond-induced spontaneous chemical binding reaction driven by both entropy and enthalpy. The results of specific curl measurement further proved the interaction between baicalin and lung, and were consistent with the results of ITC titration, indicating that ITC could be used to characterize the meridian tropism of TCM. Therefore, based on ITC, it is scientific and feasible to characterize the meridian of TCM by the energy change of the interaction between the decoction of TCM and its active components and the in vitro tissues respectively. This experiment provides a new idea for the discussion of meridian of TCM.
摘要
The outbreak of coronavirus disease (COVID-19) caused by SARS-CoV-2 virus continually lead to worldwide human infections and deaths. Currently, there is no specific viral protein-targeted therapeutics. Viral nucleocapsid protein is a potential antiviral drug target, serving multiple critical functions during the viral life cycle. However, the structural information of SARS-CoV-2 nucleocapsid protein remains unclear. Herein, we have determined the 2.7 Å crystal structure of the N-terminal RNA binding domain of SARS-CoV-2 nucleocapsid protein. Although the overall structure is similar as other reported coronavirus nucleocapsid protein N-terminal domain, the surface electrostatic potential characteristics between them are distinct. Further comparison with mild virus type HCoV-OC43 equivalent domain demonstrates a unique potential RNA binding pocket alongside the -sheet core. Complemented by binding studies, our data provide several atomic resolution features of SARS-CoV-2 nucleocapsid protein N-terminal domain, guiding the design of novel antiviral agents specific targeting to SARS-CoV-2.

OBJECTIVE@#To assess the efficacy of bone anchorage and maxillary facemask protraction devices in treating skeletal class Ⅲ malocclusion in adolescents.@*METHODS@#Articles relating to the use of bone anchorage and maxillary facemask protraction devices for treating skeletal class Ⅲ malocclusion in adolescents were searched from the databases of Cochrane Library, PubMed, EmBase, CNKI, and Wanfang database. Several inclusion and exclusion criteria were developed for the article screening. The clinical data were extracted, and the quality of the selected articles was evaluated. A Meta-analysis of SNA, SNB, ANB, ANS-Me, Wits, and U1-PP change was performed by using RevMan 5.3.@*RESULTS@#Seven studies (264 patients) were included in the Meta-analysis. Among these studies, three were randomized controlled trials, and four were non-randomized controlled trials. Compared with the maxillary facemask protraction device group, the bone ancho-rage device group had higher SNA changes and lower ANS-Me, Wits, and U1-PP changes (P<0.05). No significant differences were observed in the SNB and ANB changes between these two groups.@*CONCLUSIONS@#Compared with the maxillary facemask protraction device, the bone anchorage device can increase the extent of protraction of the maxilla and has better controls for the labial inclination of the maxillary anterior teeth in treating skeletal class Ⅲ malocclusion among adolescents. However, additional high-quality randomized controlled trials must be performed to verify the results.

摘要
Maize is a major crop in China and maize production in Heilongjiang Province ranks No.1 in the country in annual maize production in the whole country. Maize is prone to invasion by fungi and mycotoxinsproduced by these fungi are proven to be serious threats to animals as well as human health. Through high through-put sequencing we detected the dominant phylum to be Ascomycota; Dothideomycetes, Sordariomycetes, Eurotiomycetesand Tremellomycetes, Saccharomyceteswere the dominant classes; Hypocreales, Eurotiales, Capnodiales, Saccharomycetales, Tremellales, and Pleosporaleswere the main orders; Nectriaceae, Trichocomaceae, Cladosporiaceae, Debaryomycetaceae, Tremellaceae,and Pleosporaceaewere major families; Gibberella, Cladosporium, Papiliotrema, Penicillium, Scheffersomyces, Talaromyces, and Epicoccumwere the most abundant phylotypes at the genus level. Epicoccum_nigrum, Gibberella_zeae, Papiliotrema_flavescens,and Scheffersomyces_shehataewere the dominant fungal species. Great fungal diversity was observed in the maize samples harvested in the five major maize-growing regions in Heilongjiang Province. Maize-1 in Nenjiang County was observed to have the greatest fungal diversity and abundance among the five regions. Since some of the fungal species are mycotoxin producing, it is necessary to take precautions to ensure the maize is stored under safe conditions to prevent the occurrence of mycotoxins and the growth and reproduction of other fungi which results in deterioration in the quality of maize

Rice is a major food crop in China and Japonica rice production in Heilongjiang Province ranks No.1 in total annual rice production in the country. Rice is prone to invasion by fungi and mycotoxinsproduced by the fungi are proven to be serious threats to human health. The objective of the present study was to investigate fungal diversity of freshly harvested rice in the four main cultivation regions of Heilongjiang Province in order to find the difference of dominant fungi among the four regions. Through high throughput sequencing we detected Ascomycotaaccounts for absolute dominant phylum; Dothideomycetes, Sordariomycetes, Tremellomycetes, Microbotryomycetes, and Eurotiomyceteswere dominant classes; Capnodiales, Hypocreales, and Pleosporaleswere the main orders; Cladosporiaceae, Pleosporaceae, Nectriaceae, Clavicipitaceae, Tremellaceae, Phaeosphaeriaceae, Trimorphomycetaceae, Sporidiobolaceae, Bionectriaceae,and Trichocomaceaewere major family;Cladosporium, Epicoccum, Fusarium, and Alternariawere the most abundant phylotypes at genus level; Epicoccumnigrum, Gibberellazeae, and Fusariumproliferatumwere the dominant fungal species. Great fungal diversity was observed in the rice samples harvested in the four major Japonica rice-growing regions in Heilongjiang province. However, no significant difference in diversity was observed among the four regions, likely due to the relatively close geographical proximity leading to very similar climatic conditions. Since some of the fungal species produce mycotoxins, it is necessary to take precautions to ensure the rice is stored under safe conditions to prevent the production of mycotoxins. This is the first report on investigation of field fungal diversity in freshly harvested Japonica rice in Heilongjiang Province in China.

BACKGROUND: Human umbilical cord blood mesenchymal stem cells (hUC-MSCs) can repair the injury of nerve cells caused by ischemia and hypoxia, but which state of cells has a better therapeutic efficacy, primary isolation or induced differentiation is not yet known. OBJECTIVE: To compare the therapeutic effects of hUC-MSCs primary cultured and differentiated in a rat model of cerebral infarction.METHODS: After full-term delivery, fetal umbilical cord blood samples were obtained using quadruple bags by means of density gradient centrifugation. hUC-MSCS were induced in the medium containing basic fibroblast growth factor. Sixty rats were equivalently randomized into four groups: sham, model, primary culture and induced differentiation groups. Animal models of cerebral infarction were made in the rats in the latter three groups. Model rats in the primary culture and induced differentiation groups were subjected to tail vein transplantation of hUC-MSCs that were primary cultured or induced to differentiate in vitro at 7 days after modeling. RESULTS AND CONCLUSION: A marked improvement in balance, walking, spatial orientation, and learning and memory abilities was found in the rats after transplantation of hUC-MSCs that were primary cultured or induced to differentiate. Moreover, compared with the primary culture group, a significant improvement was found in the induced differentiation group, including improved pathological injury of the brain, higher expression of CD34 and Ki-67, lower expression of glial fibrillary acidic protein, lower expression of interleukin 1β and tumor necrosis factor β. Compared with the primary culture group, similar infarction size and expression of interleukin-6 were also found in the induced differentiation group. These findings indicate that hUC-MSCs with induced differentiation exhibit better therapeutic outcomes in the recovery of neurological function of cerebral infarction rats.
