RESUMO
Objective To explore ways to improve effect of antiretroviral therapy in acquired immune defi-ciency syndrome patients with comorbid malnutrition, in an effort to enhance quality of life and reduce cost. Methods 126 AIDS patients with comorbid malnutrition were randomly divided into treatment group ( n=63) and control group (n=63). Patients in the treatment group were given nutrition support besides antiretroviral ther-apy (ART), while those in the control group only received ART. After 3 months, the two groups were compared in terms of body mass index, skinfold thickness, CD4+T cell count and human immunodeficiency virus load. Re-sults The two groups were comparable before treatment in BMI, skinfold thickness, CD4+T cell count and HIV load (P>0. 05). After treatment, the treatment group, compared with the controls, had higher BMI [ (23. 23± 3. 15) kg/m2vs. (17. 25±1. 83) kg/m2], thicker skinfold [ (42. 9±6. 8) mm vs. (34. 5±5. 2) mm in males;(97. 6±17. 4) mm vs. (92. 3±14. 7) mm in females], higher CD4+T cell count (χ2=12. 573, P<0. 01), and lower HIV load (χ2=8. 683, P<0. 01). Conclusion Nutrition support may improve treatment of AIDS patients with comorbid malnutrition, as manifested in better BMI, skinfold thickness, CD4+T cell count and HIV load.
RESUMO
Objective To investigate the frequency of lesions detection in patients with cerebral infarction (CI) with SPECT/CT. To investigate fluctuation of regional cerebral blood flow (rCBF) and its relationship with clinical symptoms. Methods Sixty-seven CI patients without cerebellar lesion were randomly selected. The rCBF in the regions of interest (ROI) was examined by SPECT/CT, which was collected from the frontal lobe, temporal lobe, parietal lobe, occipital lobe, thalamus, basal ganglia and cerebellum. The rCBF index was calculated. The association between fluctuation of rCBF index and clinical symptoms of patients was explored. Results There were 251 positive regions in all viewing regions , the total positive rate was 31.2%. The left side was 38.1%, while the right side was 24.4% (χ2=17.522,P 0.05). However, the average rCBF on the left parietal lobe was lower (P 0.05). rCBF≥0.7 is a clinical sign of abnormal ROI. Conclusion 30% of ROI of CI patients have lesions and the positive rate of the left side was higher. The biological rCBF values of all lobes were different. Therefore, rCBF index could be used to reflect whether the ROI is normal. rCBF≥0.7 could be used as a sign to quantitatively assess abnormal ROI in clinical practice.
