Correlation between abnormal thyroid parenchymal echogenicity and thyroid function changes in health examination population / 中华健康管理学杂志

Objective:To explore the relationship between thyroid parenchymal echogenicity abnormalities and thyroid function evolution in health examination population.Methods:It was a cohort study. According to the inclusion and exclusion criteria, participants were selected from individuals who underwent thyroid color ultrasound and thyroid function tests at the Health Management Center of Tianjin Medical University General Hospital from January to December 2017. Data including age, gender, smoking history, alcohol consumption history, personal medical history, and thyroid function re-examination information were collected. Follow-up was conducted until the occurrence of thyroid function abnormalities or until the end of the follow-up period. The cumulative incidence rate and incidence density of thyroid function abnormalities were evaluated. Cox regression analysis was used to analyze the relationship between thyroid parenchymal echogenicity abnormalities and thyroid function evolution.Results:A total of 6 754 participants were included in this study, with an average age of (45.80±12.12) years, and females accounted for 42.7%. The mean follow-up time was 1.82 years, with a cumulative follow-up duration of 12 263 person-years. During the follow-up period, 154 new cases of thyroid function abnormalities occurred, with a cumulative incidence rate of 2.28% (95% CI: 1.94%-2.66%) and an incidence density of 12.56/1 000 person-years (95% CI: 10.66/1 000-14.69/1 000 person-years). The multivariate adjusted Cox regression analysis showed that individuals with thyroid parenchymal echogenicity abnormalities had a significantly increased risk of developing isolated thyroid stimulating hormone abnormalities and thyroid function abnormalities, with HR(95% CI) of 3.09 (2.02-4.73) and 2.92(1.96-4.33), respectively, both P<0.001. Stratified analysis showed that, except for body mass index <18.5 kg/m 2, current smoking, and current alcohol consumption, all other stratified factors showed a significant increase in the risk of thyroid function abnormalities in individuals with thyroid parenchymal echogenicity abnormalities. Conclusion:Thyroid parenchymal echogenicity abnormalities are important risk factors for the evolution of thyroid function abnormalities. Continuous monitoring of thyroid function should be given due attention.

STUDIES ON PHARMACOLOGICAL ACTIVITY OF MYCENA DENDROBII / 微生物学通报

The pharmacological activity of Mycena dendrobii Fan et Guo, a new species of endophytic fungus was studied. It was revealed that the mycelia methanol extracts and the fermentation liquid ethanol extracts of Mycena dendrobii showed anglgesic effect to mice, which have the correlations to that of the traditional Chinese medicine ‘shihu’. The fermentation liquid ethanol extracts of Mycena dendrobii showed excitation effect to central nervous system of mice. Then the effective parts of anglgesic effect was determined.

Studies on the Pharmacology of Cajanin Preparation / 中草药

Cajanin preparation could significantly reduce the mouse pinna inflammation iuduced by croton oil. The higher the dose, the stronger the effect .It also inhibited the infiltration increase of intraperitoneal blood capillary of mice led by acetic acid.In addition, the preparation had an analgesic effect. These experimental results indicated that cajanin may be hopefully developed to a new drug for the treatment of scald trauma, and infection.
