Objective:To compare the contents of notoginsenoside R1 , ginsenoside Rg1 and ginsenoside Rb1 between Notoginseng Radix et Rhizoma and its formula granules. Methods:An HPLC method was used with a SunFire C18 column (250mm × 4. 6 mm, 5μm),the flow rate was 1. 0 ml·min-1, the detection wavelength was set at 203 nm, and the column temperature was at 30 ℃. The mobile phase was acetonitrile( A)-water( B) with gradient elution. An HPLC was used to determine the contents of the three ingredi-ents between Notoginseng Radix et Rhizoma and its formula granules, and compare the differences. Results: The total content of the three ingredients in Notoginseng Radix et Rhizoma and its formula granules was 9. 214% and 8. 646%, respectively. The total content of the three ingredients was equivalent and the daily amount of the major components in the commercial formula granules was equivalent with that in the decoction of Notoginseng Radix et Rhizoma. Conclusion:The production process of the original formula granules is re-liable, and the quality of formula granules of Notoginseng Radix et Rhizoma is stable.

Objective To compare the contents of forsythoside A and forsythin in Fructus Forsythia and its dispensing granule. Methods HPLC-gradient elution method was used with SunFire C18 column (4.6 mm×250 mm, 5μm), mobile phase A of acetonitrile and B of acetic acid, flow rate of 1.0 mL/min, detection wavelength of 277 nm, and column temperature at 30 ℃. HPLC was used to determine the contents of forsythoside A and forsythin in Fructus Forsythia and its dispensing granule, and compare the difference between the two contents. Results The content of forsythoside A in dispensing granule was less than that of raw material of Fructus Forsythia, and the concentration of the major components in the commercial Lianqiao Granule were not equivalent to that in the decoction of Fructus Forsythia. The content of forsythin in dispensing granule was equivalent with that of raw material of Fructus Forsythia. Conclusion The original formula granule production process needs to be improved, and the standardized criteria for the quality control and reasonable quality standard of granule should be established.

Objective: To study the dynamic changes of type Th22 cell immunological response during atherosclerosis process in experimental mice in order to provide a new theoretical basis for atherosclerosis therapy. Methods: 8 weeks C57BL/6J mice were divided into 2 groups: Experiment group,n=24 ApoE-/- mice and Control group, n=24 normal mice. All animals received high fat diet and the following indexes were compared between 2 groups at 0, 4, 8, 12 weeks after treatment: aortic atherosclerotic lesions were deifned by Oil red O staining, dynamic changes of Th22 cells in spleen were measured by lfow cytometry, mRNA expressions of interleukin-22 (IL-22), IL-22R1, AhR and T-bet in aorta were examined by RT-PCR, blood levels of IL-22 was detected by ELISA. Results: Compared with Control group, Experiment group had the increased area of aortic atherosclerosis (the ratio of plaque area/lumen area) and Th22 cell (CD4+ IL-22+/CD4+T cell) amount, elevated mRNA expressions of IL-22, IL-22R1, AHR, T-bet in aorta and higher blood levels of IL-22 at all time points, the differences between each time point (except 0 week) had the statistic meaning,P<0.05. In Experiment group, the differences between 2 adjacent time points, for the area of aortic atherosclerosis and mRNA expressions of AHR, T-bet: 4 weeks vs 0 week, 8 weeks vs 4 weeks, 12 weeks vs 8 weeks all had statistic meaning; for Th22 cell amount: 4 weeks vs 0 week, 8 weeks vs 4 weeks had statistic meaning and 12 weeks vs 8 weeks had no real distinction; for mRNA expressions of IL-22, IL-22R1 and blood levels of IL-22: 4 weeks vs 0 week had statistic meaning and 8 weeks vs 4 weeks, 12 weeks vs 8 weeks had no real distinctions. Conclusion: Hyperactive immunological response of Th22 cells might be involved in atherosclerosis process, the relevant mechanism should be further studied.

At present, severe acute respiratory syndrome coronavirus-2(SARS-CoV-2)infection is still rampant worldwide.As of September 10, 2021, there were about 222 million confirmed cases of corona virus disease 2019(COVID-19)and more than 4.6 million deaths worldwide.With the development of COVID-19 vaccines and the gradual vaccination worldwide, the increasing number of cases in children and unvaccinated young people has drawn attention.According to World Health Organization surveillance data, the proportion of COVID-19 infection cases in children gradually increased, and the proportion of cases in the age groups of under 5 years and 5-14 years increased from 1.0% and 2.5% in January 2020 to 2.0% and 8.7% in July 2021, respectively.At present, billions of adults have been vaccinated with various COVID-19 vaccines worldwide, and their protective effects including reducing infection and transmission, reducing severe disease and hospitalization, and reducing death, as well as high safety have been confirmed.Canada, the United States, Europe and other countries have approved the emergency COVID-19 vaccination in children and adolescents aged 12 to 17 years, and China has also approved the phased vaccination of COVID-19 vaccination in children and adolescents aged 3 to 17 years. For smooth advancement and implementation of COVID-19 vaccination in children, academic institutions, including National Clinical Research Center for Respiratory Diseases, National Center for Children′s Health, and The Society of Pediatrics, Chinese Medical Association organized relevant experts to reach this consensus on COVID-19 vaccination in children.
