ABSTRACT
Objective To survey the incidence of sleep disorders among patients with industrial injuries and analyze the relevant factors.MethodsA total of 112 depressed patients ( male 106,female 6; aged 22-79 years,course of disease 35 d-25 years) were assessed by a professional psychologist using life satisfaction index A,the type A behavior pattern scale,the Pittsburgh sleep quality index (PSQI) and the Barthel index.ResultsThe incidence of disordered sleep was 40.18％ (45/112),of whom mildly depressed patients were 34.29％,moderately depressed patients 42.86％ and severely depressed patients 85.71％.The incidence of sleep disorders increased with increasing depression severity.The incidence of disordered sleep was significantly higher among the severely depressed patients than among those mildly or moderately depressed,but there was no significant difference in incidence between moderately and mildly depressed patients.PSQI scores among the severely and moderately depressed patients were significantly higher than among those mildly depressed,but there was no statistically significant difference in average PSQI scores between the severely and moderately depressed patients.The sleep disorder group suffered significantly poorer sleep quality and took significantly longer to get to sleep.There were no significant differences in average age,educational level,marital status,social relations,family and social support,gender distribution or course of disease between the two groups.There were,however,significant differences in family income,life satisfaction,character type and disease species between the groups.ConclusionThe incidence of disordered sleep among depressed patients after industrial injury is correlated with the severity of depression,family income,life satisfaction,the type of injury and the patient's character.
ABSTRACT
Objective To evaluate the value of high-frequency ultrasound for diagnosing Duchenne muscular dystrophy.Methods Eighty-one cases with Duchenne muscualr dystrophy were divided into four groups according to their age,age 3-7(13 cases),age 7-10 (30 cases), age 10-13 (30 cases),age 13-14 (8 cases). Twenty cases of healthy children, aged from 1 to 11 were chosed as controls. In all groups' buttock muscle,thigh and leg muscle were observed by high-frequency ultrasound longitudinally and horizontally.Results Gluteus atrophy and subcutaneous fat thickening were seen in age 3 patients,progressive subcutaneous fat thickening and progressive muscular atrophy of buttock,thigh and leg with age were proved.There were significantly differences among groups ( P
ABSTRACT
AIM: To investigate the changes on immunological function in antigen-sensitized mice injected by dermatophagoides farinaeliposomes (DF) subcutaneously. METHODS: BALB/c mice were sensitized with DF antigen injected subcutaneously. After injected by DF liposomes with 1, 3, and 9 ?g?g -1 dosage respectively, the total IgE, total IgG, DF specific IgE(sIgE), DF specific IgG (sIgG), IL-4, and IFN-? were detected by ELISA. RESULTS: The total IgE, sIgE, total IgG, and sIgG in the serum of sensitized mice increased, the level of IFN-? reduced and IL-4 increased. After injected subcutaneously by DF liposomes, the total IgE, sIgE and IL-4 in the serum of mice of all the treatment groups reduced, and IFN-? raised, and the total IgG, sIgG raised in the serum of mice administrated with small and medium dosage, but the low dosage was more obvious. CONCLUSION: DF liposomes have some effects on the immunological function in mite-sensitized mice in the low dosage.
