The purpose of this study was to establish the phospho-specific flow cytometry (phospho-flow) to detect the phosphorylated signaling proteins of leukemia cells and to evaluate its useful value in leukemia study. The bone marrow of leukemia children was collected, and treated by phospho-flow of extracted mononuclear cells (MNC) and phospho-flow of directly fixed bone marrow (BM) respectively. In phospho-flow of extracted MNC, the MNC extracted from BM were fixed and permeabilized, then were cultured with P-AKT and P-ERK1/2, finally were analyzed by flow cytometry. In phospho-flow of directly fixed BM, the BM was treated with fixation/lysis buffer and 90% methanol, then were incubated with the surface CD antibody, P-AKT and P-ERK1/2, finally the treated BM cells were analyzed by flow cytometry. The results showed that the positive rates of P-AKT and P-ERK1/2 in MNC treated by phospho-flow of extracted MNC of 26 leukemia children were 46.2% and 30.8% respectively, while the positive rates of P-AKT and P-ERK1/2 in BM treated by phospho-flow of directly fixed BM were 50.0% and 38.5% respectively. The comparison of positive rates of P-AKT and P-ERK1/2 between the 2 treatment protocol showed no difference (p > 0.05). It is concluded that the phospho-flow of directly fixed BM established by our laboratory can be used to analyze the signaling proteins of leukemia cells.

OBJECTIVE: To compare the eradication rate, adverse reactions and compliance of the two 14-day bismuth-containing quadruple therapies in Liaoning Province as the first-line Helicobacter pylori(HP) eradication programs. METHODS: We collected222 eligible HP-infected patients who were admitted to the First Affiliated Hospital of China Medical University from March 2017 to October 2018 and treated with either of the following two programs:(1) EBLA group: esomeprazole(20 mg, twice a day), bismuth(200 mg, twice a day), levofloxacin(200 mg, twice a day) and amoxicillin(1 g, twice a day), 111 cases in total;(2) EBCA group:esomeprazole(20 mg, twice a day), bismuth(200 mg, twice a day), clarithromycin(500 mg, twice a day) and amoxicillin(1 g, twice a day), 111 cases in total. The patients in both groups were given medicines for 14 days, and the 13 C breath test was performed after4 weeks of withdrawal. RESULTS: The eradication rate of EBLA group was 87.34%(95%CI 80.9%-93.9%), and that of EBCA group was 83.33%(95%CI 76%-90.7%).There was no significant difference between the two groups(P=0.413). The incidence of adverse reactions was 10.8% in EBLA group and 26.13% in EBCA group. The difference was statistically significant(P=0.003). The compliance of patients in EBLA group was 99.10%, and that of EBCA group was 98.20%. The difference was not statistically significant(P=0.561).CONCLUSION: Both EBLA program and EBCA program can achieve good eradication rate and compliance in Liaoning province. The incidence of adverse reactions in EBLA group is lower than that in EBCA group, which is the preferred first-line HP eradication program.

Objective To evaluate the safety and epidemiological effects on the first mass vaccination program, using the China-made A (H1N1) influenza vaccine. Methods Descriptive epidemiology and cohort study design were used to assess the influenza A H1N1 vaccine on its safety and epidemiological effects. Results 95 244 subjects were immunized with A (H1N1) influenza vaccine. 193 adverse events were reported through AEFI Management System, with the Reported rates after immunization was carried out. Of 81 adverse reactions confirmed to be related to immunization,reported through the AEFI Management System. The epidemiological protection rate of A (H1N1)influenza vaccine showed a similar safety profile to seasonal flu vaccine. The vaccine demonstrated a good epidemiological effects against A (H1N1) influenza virus infection.

Objective To evaluate the cells for producing vaccine of avian influenza H10 subtype, the growth characteristics of influenza H10 subtype reassortant viruses in different cells ( MDCK and Vero) were investigated.Methods Reassortant viruses, RG-H10N1(7 +1) and RG-H10N8(6 +2), between wild-type virus A/Jiangxi-donghu/346/2013 ( JXH10N8 ) and high-yielding virus A/Puerto Rico/8/34 ( PR8) were constructed with reverse genetic system.Viruses were propagated in SPF embryonated chicken eggs.The growth characteristics of the two reassortant viruses were compared after inoculating MDCK and Vero cells respectively, with RG-PR8 as the control.Viral growth characteristics were studied at different MOI in MDCK cells.Results All viruses could be detected TCID50 in MDCK cells.RG-PR8 and RG-H10N1could be detected TCID50 in Vero cells but not RG-H10N8.There were no significant difference in HA titer between the two reassortant viruses at the same MOI, but both reassortant viruses exhibited lower HA titers than that of PR8 in MDCK cells.Conclusion Both influenza H10 subtype reassortant viruses grew better in MDCK cells.MDCK cells are more sensitive to the influenza H10 reassortant viruses, and NA from different subtypes could affect the grow capability of reassortant viruses in Vero cells.

We used exogenous GA_3 to break the seed dormancy of Thesium chinense. We used high-throughput sequencing technology was used to sequence the transcriptome of dormant seed embryos and dormancy breaking seed embryos of Th. chinense, and the data was analyzed bioinformatically and systematically. The results showed that exogenous GA_3 could effectively break the seed dormancy of Th. chinense; 73 794 up-regulated genes and 42 776 down regulated genes were obtained by transcriptome sequencing; 116 570 diffe-rential genes were annotated by GO function to GO items such as metabolism process, cell process, cell, cell component, binding and catalytic activity. A total of 133 metabolic pathways were found by Pathway analysis of 26 508 differentially expressed genes. In the process of dormancy release, DEGs were mainly enriched in translation, carbohydrate metabolism, folding, classification, degradation and amino acid metabolism. Based on the annotation results in KEGG database, 20 metabolic pathways related to dormancy release were found. Dormancy release of Th. chinense seeds is a complex biological process, including cell morphology construction, secondary metabolite synthesis, sugar metabolism and plant signal transduction, among which plant hormone signal transduction is one of the key factors to regulate dormancy release. The results of qRT-PCR showed that the sequencing results were consistent with the actual results.

OBJECTIVE: To overview the methodological quality, report quality and evidence quality of the systematic review (SR) of acupuncture for vascular cognitive impairment ( VCI ). METHODS: The SRs regarding acupuncture for VCI were searched in PubMed, Cochrane Library, EMbase, CNKI, SinoMed, Wanfang and VIP databases. The retrieval period was from the establishment of the database to September 24, 2020. The report quality, methodological quality and evidence quality of the included SRs were evaluated by PRISMA statement, the AMSTAR 2 tool and the GRADE system. RESULTS: A total of 22 SRs were included, including 102 outcome indexes. The methodological quality was generally low, with low scores on items 2, 5, 7, 10, 14, 15 and 16. The report quality was good, with scores ranging from 19 points to 24.5 points. The problems of report quality were mainly reflected in the aspects of structural abstract, program and registration, other analysis and funding sources. The level of outcome indexes of SRs was mostly low or very low, and the main leading factor was limitation, followed by inconsistency and inaccuracy. CONCLUSION Acupuncture for VCI is supported by low quality evidence of evidence-based medicine, but the methodological quality and evidence body quality of relevant SRs are poor, and the standardization is needed to be improved.

The existing problems in the outcomes of randomized controlled trials (RCTs) of acupuncture for vascular cognitive impairment (VCI) during recent five years are analyzed and suggestions are proposed. The RCTs of acupuncture for VCI were selected in PubMed, EMbase, Cochrane Library, Clinical Trials, CNKI database, Wanfang database, VIP database, SinoMed database and Chinese Clinical Trial Registry (ChiCTR) from January 1, 2015 to September 14, 2020. The outcomes were extracted and analyzed. As a result, 21 RCTs were included and the outcomes used were divided into 9 categories: clinical symptom/sign indexes, quality of life indexes, neuroimaging indexes, neuroelectrophysiology indexes, blood biochemical indexes, hemorheology indexes, TCM syndrome score indexes, clinical efficacy indexes, and safety indexes. Among them, the top three of the most used outcomes were clinical symptoms/signs indexes (21, 100.0%), clinical efficacy indexes (14, 66.7%) and quality of life indexes (12, 57.1%). In the RCTs of acupuncture for VCI, attention should be paid to distinguish the primary outcomes and secondary outcomes, adopt objective and standardized efficacy evaluation, and give consideration to report the outcomes of safety, health economic and TCM characteristic indexes.
