Objective To explore the effects of lipoteichoic acid(LTA)on phagocytosis of peritoneal maerophages and NO production in vitro.Methods The peritoneal macrophages that were isolated sterilely from Kunming mice were divided into two groups:co-culture with RPMI 1640,and pretreatment with dexamethasone(DEX).Then,the LTA isolated from BFA with different final concentrations(5,10,20 and 40 ug/ml) was added.After the peritoneal macrophages were cultured for 4 and 24 h,the effects of LTA on cytophagocytesis and NO production in vitro were determined respectively by using neutral red and NO assay kit.Results LTA with final concentrations of 5,10,20 and 40/μg/mL significantly promoted the phagocytosis of peritoneal macrophages and production of NO(P<0.05).It also effectively antagonized the inhibitory response of DEX against peritoneal macrophages(P<0.05).The higher concentration of LTA,the stronger effect.Conclusion Not only can LTA stimulate and activate the peritoneal macrophages significantly,but also antagonize the inhibition from DEX in vitro.

Ischemic stroke in young adults has attracted more and more attention due to the diversity of its etiology. Although atherosclerosis is the most common cause of stroke in young adults, other or unknown causes are not uncommon . To improve clinicians′ understanding of the etiological diagnosis of stroke in young adults, this article reports a case of ischemic stroke in the First Affiliated Hospital of Jinan University. The patient was a 22-year-old male with acute onset who was diagnosed with acute ischemic stroke based on clinical presentation, physical examination, and magnetic resonance imaging of the brain. After actively searching for the cause, laboratory and genetic tests revealed that the patient had inherited thrombophilia (protein C and protein S deficiency), and cardiac magnetic resonance imaging examination found that the patient had noncompaction of the ventricular myocardium.

Objective To observe the effect of yin-tonifying and fire-removing prescription on IL-10 and IL-18 in systemic lupus erythematosus patients with syndrome of internal heat due to yin deficiency.Methods A total of 86 systemic lupus erythematosus patients with syndrome of internal heat due to yin deficiency were enrolled and randomly divided into control group and research group,43 cases in each group.The control group was treated with conventional western medicine,while research group was treated with yin-tonifying and fire-removing prescription on basis of control group.The TCM symptom score,serum IL-10 and IL-18 levels and the incidence rate of adverse reactions were compared between the two groups.The clinical efficacy of the two groups was evaluated.Results Mter treatment,the levels of IL-10 and IL-18 in both group decreased significantly,and the levels in research group were significantly lower than control group (P ＜ 0.05).The total effective rate was 95.35％ in research group,which was significantly higher than 69.77％ in the control group (P ＜ 0.05).The incidence rate of adverse reactions was 6.98％ in the research group,whichwas similar to 9.30％ in the control group (P ＞ 0.05).Conclusion For systemic lupus erythematosus patients with syndrome of internal heat due to yin deficiency,yin-tonifying and fire-removing prescription can significantly improve the clinical efficacy,alleviate clinical symptoms,and will not increase the incidence rate of adverse reactions.

Objective:To explore the impact of whole blood organophosphate esters (OPEs) flame retardant exposure on thyroid function-related hormones in healthy older adults.Methods:In this panel study, five repeated population-based epidemiological surveys and biological sample collection were conducted from September 2018 to January 2019, with 76 healthy older adults aged 60-69 years in the Dianliu Community of Jinan, Shandong Province. Information on the sociodemographic characteristics, diet, and health status of the respondents was systematically gathered through questionnaires and physical examinations. Fasting venous blood was collected to determine the levels of OPEs, thyroid-stimulating hormone (TSH), triiodothyronine (T 3), and thyroxine (T 4). A linear mixed-effects model was used to analyze the impact of OPEs exposure on thyroid function-related hormones in healthy older adults. Results:Each of the 76 subjects participated in at least two follow-up visits, resulting in a total of 350 person visits. The age of the study participants was (65.07±2.76) years, with 38 participants of both sexes. A total of eight OPEs were included with a detection rate exceeding 50%, and the M ( Q 1, Q3) for ∑OPEs was 3.85 (2.33, 5.74) ng/ml, with alkyl-OPEs being the major type of OPEs with an M ( Q 1, Q3) of 1.27 (0.64, 2.50) ng/ml. The M ( Q 1, Q3) for TSH, T 3, and T 4 was 3.74 (2.55, 5.69) μIU/ml, 1.32 (1.10, 1.60) ng/ml, and 45.04 (36.96, 53.27) ng/ml, respectively. Linear mixed-effects model showed that TSH was significantly decreased by 9.93% (95% CI:-15.17%, -4.36%) and 11.14% (95% CI:-15.94%, -6.06%) in older adults for each quartile level increase in TnBP and TEHP exposures, respectively. Gender-stratified analysis indicated that TEHP exposure was negatively associated with TSH levels in male older adults, whereas a decrease in TSH levels among female older adults was associated with TnBP exposure. Conclusion:Exposure to whole blood OPEs is associated with decreased TSH levels among healthy older adults, with notable gender differences.
