OBJECTIVE:To evaluate the characteristics and regularity of adverse drug reactions (ADR) in children's hospital. METHODS:The clinical drug use and ADR of 3 653 children during 2006~2008 in our hospital were analyzed statistically by designing a child medication registration form. RESULTS:The incidence of 498 ADR cases was about 13.63%; ADR were mostly occurred in 1~3 year-old children(36.14%); 71.29% were caused by intravenously; 66.87% were induced by antibiotics; ADR were more common in spring and winter. CONCLUSION:The drugs have a dual nature. Moreover,children belong to a special group. The measures such as strictly mastering clinical indications,reducing irrational drug use,sufficient therapy and avoiding or reducing the occurrence of ADR can guarantee children grow healthily.

Objective:
To preliminary analysis of the characteristics of lymphocyte subsets in peripheral blood among 135 cases of coal worker’s pneumoconiosis patients in Huainan mining area.
Methods:
The peripheral bloods of 135 cases of coal worker’s pneumoconiosis patients and 112 cases of health examiners were collected. Flow cytometry was used to detect peripheral blood lymphocytes, T cell subsets and CD4+CD25+ regulatory T cells.
Results:
Compared with the control group, CD64 index of granulocytes and lymphocytes was slightly higher. The total T cells (CD3+) increased in peripheral blood, CD4+ expression was reduced and CD8+ expression was increased in infection group, CD4+/CD8+ ratio was inverted, the differences between the infection group and the control group were statistically significant (

Objective :
To investigate the expression levels and clinical significance of cold-inducible RNA-binding protein ( CIRBP) and triggering receptor expressed on myeloid cells-1 (TREM-1) in peripheral blood of patients with chronic obstructive pulmonary disease ( COPD) .
Methods :
Forty hospitalized COPD patients from October 2022 to June 2023 were selected as the acute exacerbation group.After treatment,they entered the stable phase and were included in the stable phase group.During the same period,40 healthy individuals underwent physical exami- nations as the control group.General information from each group was collected,peripheral blood was collected,and the levels of CIRBP and TREM-1 in plasma were measured using enzyme -linked immunosorbent assay (ELISA) . The relative expression levels of CIRBP mRNA and TREM-1 mRNA were measured using real-time fluorescence quantitative polymerase chain reaction (qRT-PCR) ,and lung function was measured in COPD patients and healthy individuals.
Results :
The expression levels of CIRBP and TREM-1 in peripheral blood during the acute exacerba- tion of COPD were higher than those in the stable phase group,and the differences were statistically significant (all P<0. 001) ; The expression levels of CIRBP and TREM-1 in peripheral blood during acute exacerbation and stable phases were higher than those in the control group,and the differences were statistically significant ( all P < 0. 001) ; In both acute exacerbation and stable phases,CIRBP levels were positively correlated with TREM-1 levels ; The levels of CIRBP and TREM-1 during acute exacerbation were positively correlated with white blood cell count, neutrophil percentage,neutrophil to lymphocyte ratio ; The stable CIRBP and TREM-1 levels were negatively correla- ted with the percentage of forced expiratory volume at 1 second to the expected value,and the ratio of forced expira- tory volume to forced vital capacity at 1 second.They were positively correlated with white blood cell count,neutro- phil percentage,and neutrophil / lymphocyte ratio.
Conclusion
The expression levels of CIRBP and TREM-1 are el- evated in the peripheral blood of COPD patients.The expression of CIRBP is correlated with TREM-1 expression, and is associated with clinical indicators such as lung function,white blood cell count,neutrophil percentage,neutro- phil to lymphocyte ratio,monocyte to high-density lipoprotein ratio,etc.,suggesting that CIRBP and TREM-1 may jointly participate in the occurrence and development of COPD.

BACKGROUND:Temporomandibular joint osteoarthritis can cause severe pain,which significantly affects the patient's quality of life and psychological health.Studies have found that medical ozone can effectively alleviate pain due to temporomandibular joint osteoarthritis,but its analgesic effect and mechanism are still unclear. OBJECTIVE:To explore the effects of medical ozone on pain relief in temporomandibular joint osteoarthritis and the potential mechanisms. METHODS:Twenty-four Sprague-Dawley rats were randomly divided into four groups(n=6 per group):control group,model group,air group,and medical ozone group.A sodium iodate-induced rat model of temporomandibular joint osteoarthritis was established in all groups except for the control group.After 1 week of modeling,rats in the air group and medical ozone group were injected with clean air and medical ozone,respectively,in the temporomandibular joint.The injection frequency for the air group and medical ozone group was once a week for three times in total.The von Frey mechanized pain measurement technique was used to assess the mechanical pain threshold of the temporomandibular joint in rats before and 28 days after modeling.ELISA was utilized to detect interleukin-1β in both serum and temporomandibular joint fluid at 28 days after modeling.Histopathologic changes of the temporomandibular joint were evaluated through hematoxylin-eosin staining.Additionally,the expression levels of hypoxia-inducible factor 1α and cyclooxygenase 2 in the temporomandibular joint were analyzed using immunohistochemistry. RESULTS AND CONCLUSION:Compared with the control group,the mechanical pain thresholds of the temporomandibular joint in the model group were decreased at 1,3,7,14,21,and 28 days after modeling(P<0.01);and compared with the model and air groups,the mechanical pain thresholds of the temporomandibular joint in the medical ozone group were increased at 28 days after modeling(P<0.01).Compared with the control group,the level of interleukin 1β in the serum and joint fluid of rats in the model group was elevated(P<0.01);compared with the model and air groups,the level of interleukin 1β in the serum and joint fluid of rats in the medical ozone group was decreased(P<0.01).Hematoxylin-eosin staining results showed derangement and degeneration of the cartilage structure in the model group and the air group,while the derangement of the cartilage structure in the medical ozone group was less than that in the model group and the air group.Immunohistochemical staining showed that the expression of hypoxia-inducible factor 1α and cyclooxygenase 2 in the temporomandibular joints of rats in the model group was elevated compared with that in the control group(P<0.01);the expression of hypoxia-inducible factor 1α and cyclooxygenase 2 in the temporomandibular joints of rats in the medical ozone group was decreased compared with that in the model group and the air group(P<0.01,P<0.05).These findings suggest that medical ozone can alleviate the pain caused by osteoarthritis of the temporomandibular joints in Sprague-Dawley rats by reducing the expression of hypoxia-inducible factor 1α,interleukin 1β,and cyclooxygenase 2.
