Objective To analyze the epidemic characteristics of influenza in children in Jinshan District of Shanghai,so as to provide scientific basis for prevention and control of influenza in children. Methods We analyzed the surveillance data as well as the results of virus isolation and identification in children with influenza-like illness (ILI) in Jinshan District of Shanghai from January 2010 to December 2019. Results There were two annual epidemic peaks in 2010, 2016, 2017 and 2018, one annual epidemic peak in winter and spring in 2011 and 2013, and two annual epidemic peaks in 2012, 2014, 2015 and 2019. A total of 3 859 ILI cases were collected in the past 10 years, and 848 positive virus strains were isolated, with a positive rate of 21.97%. Among them, 371 were seasonal H3N2, 163 were new H1N1, 314 were type B(among them, 226 were yamagata and 88 were victoria). The positive rates of influenza virus in different children groups were 0.88% in scattered children, 6.76% in kindergarten children, and 14.33% in students, respectively (

OBJECTIVE:
Hemorrhoidal disease (HD) is the most common proctological disease, with an estimated prevalence rate of 4.4%, and a peak in individuals between 45 and 65 years of age. This study was done to evaluate whether Lian-Zhi-San (LZS), a clinically used anti-hemorrhoidal ointment could alleviate the inflammatory injury, with its associated changes of inflammatory cytokines and morphology of anorectal tissues, in an experimental model of HD in rats.
METHODS:
HD was induced by croton oil preparation (COP) applied to the anorectal region. Rats were then treated with cotton swabs soaked in LZS ointment, water or white vaseline, twice a day for 7 d. At the end of the experiment, HD was evaluated by measuring hemorrhoidal and biochemical parameters along with histopathological observations.
RESULTS:
In this study, COP induced a significant increase in the macroscopic severity score, anorectal coefficient and Evans blue extravasation, compared to normal rats. Additionally, it greatly enhanced the expression and secretion levels of some important inflammation-related cytokines along with marked histological damage, compared to normal rats. Rats treated with LZS ointment experienced significantly ameliorated Evans blue extravasation (P < 0.05), decreased macroscopic severity score (0.86 ± 0.14 vs. 1.65 ± 0.16) and the anorectal coefficient (P < 0.01); its use also attenuated tissue damage and inhibited the expression and secretion levels of inflammation-related cytokines (interleukin-1β, interleukin-6 and tumor necrosis factor-α).
CONCLUSION
This study validates a preliminary understanding of the use of LZS ointment to treat inflammatory factors and tissue damage in an experimental model of HD in rats.

Mongolian medicine (MM) is an important part of Mongolian culture. Exploration of MM can play a crucial role in the prevention and treatment of various diseases and can help provide better health care globally. In this article, we gave a brief introduction to the origin and development of MM, the theoretical system of MM, the principles of Mongolian materia medica formula, the modern research on Mongolian materia medica and the quality control of Mongolian materia medica. The present situation and outlook of MM were also discussed.

Objective To investigate the effect of ginkgolide B (GB) on cysteinyl aspartate specific proteinase-3 (Caspase-3)/chromosome 10 deletion phosphatase-tension protein homologue (PTEN)/protein kinase B (Akt) pathway and cell proliferation and apoptosis in hypoxia/reoxygenation cardiomyocytes. Methods H9C2 cells were cultured in vitro. A control group was cultured in serum-free DMEM high glucose medium at 37°C and 5% CO2 for 28 hours. The remaining groups were prepared with hypoxia/reoxygenation models. A GB low-dose group and a GB high-dose group were treated with GB pretreatment with final concentration of 50 μmol/L and 200 μmol/L respectively at 1 h before hypoxia/reoxygenation. A carvedilol group was treated with carvedilol of a final concentration of 10 μmol/L at 1 h before hypoxia/reoxygenation. The proliferation and apoptosis of H9C2 cells were detected, and the levels of lactate dehydrogenase (LDH), malondialdehyde (MDA), reactive oxygen species (ROS), PTEN, Akt, phosphorylated Akt (p-Akt) and Caspase-3 in H9C2 cells were also detected. Results Compared with the control group, the proliferation rate of H9C2 cell, and the levels of PTEN, Akt and p-Akt in other groups decreased, and the apoptosis rate, and the levels of LDH, MDA, ROS and Caspase-3 increased (P<0.05). Compared with the hypoxia/reoxygenation group, the proliferation rate of H9C2 cell, and the levels of PTEN, Akt and p-Akt in all GB dose groups and the carvedilol group increased; the apoptosis rate, and the levels of LDH, MDA, ROS and Caspase-3 decreased, and the effect of GB was in a dose dependent manner; however, the effect of GB was not as strong as carvedilol (P<0.05). Conclusion GB can inhibit H9C2 cell apoptosis and promote H9C2 cell proliferation by activating Caspase-3/PTEN/Akt pathway.
