OBJECTIVETo explore the clinicopathological correlation between CD4(+) T lymphocyte count and superficial lymphadenopathy HIV/AIDS patients.

METHODSA total of 1066 HIV/AIDS patients were included in this study. The incidence of superficial lymphadenopathy, peripheral blood CD4(+) T lymphocyte counts and histological features of superficial lymphadenopathy were analyzed.

RESULTSAmong 1066 patients, 126 cases (11.8%) presented with superficial lymphadenopathy. Of the 126 cases, there were 69 cases with CD4(+) T lymphocyte counts < 100/µl and clinical diagnoses including tuberculosis (37 cases), reactive hyperplasia (8 cases), AIDS-related lymphadenopathy (18 cases), penicillium diseases (12 cases), fungal infection (5 cases) and non-tuberculous mycobacterial infection (1 case). Twenty-six cases had CD4(+) T lymphocyte counts between 100/µl to 200/µl and clinical diagnosis including tuberculosis (12 cases), reactive hyperplasia (8 cases), AIDS-related lymphadenopathy(6 cases), penicillium disease (2 cases) and non-Hodgkin lymphoma (1 case). Twenty-nine cases had CD4(+) T lymphocyte counts > 200/µl and clinical diagnoses including tuberculosis (11 cases), reactive hyperplasia (12 cases), AIDS-related lymphadenopathy (3 cases), Penicillium diseases (1 case) and non-Hodgkin lymphoma (4 cases). The CD4(+) T lymphocyte counts among patients with tuberculosis, AIDS-related lymphadenopathy and Penicillium diseases were significantly different (χ(2) = 8.861, P = 0.012). A significant correlation between the incidence of superficial lymphadenopathy and CD4(+) T lymphocyte counts was found (χ(2) = 375.41, P = 0.000).

CONCLUSIONSThe most common cause of superficial lymphadenopathy in HIV/AIDS patients is tuberculosis, followed by lymph node reactive hyperplasia, AIDS-related lymphadenopathy and Penicillium disease. Low CD4(+) T lymphocyte count correlates with an increased incidence of superficial lymphadenopathy and the risk of opportunity infection. Therefore, determination of peripheral blood CD4(+) T lymphocyte count should become an integral marker for the early diagnosis and treatment of superficial lymphadenopathy in HIV/AIDS patients.

Aim To study the effect of three kinds of active ingredients of traditional Chinese medicine (sinomenine, rhynchophylline and isorhynchophylline) on dre-miR-723-5p expression in morphine-induced zebrafish brain. Methods Morphine was injected intraperitoneally to zebrafish, conditional position preference (CPP) was trained and then the behavioral of animals were observed; the miRNA expression profiles of morphine-additive zebrafish were determined by small RNA sequencing; qRT-PCR was used to verify the expression of dre-miR-723-5p, three target gene databases (miRanda, miRDB, andRNAhybrid) were used to predict the target genes of dre-miR-723-5p; Kobas 3.0 was used to perform Gene Ontology (GO) and KEGG pathway analysis of these target genes. Results Morphine-induced CPP model was established successfully. Compared with control group, the resident time and movement map in drug-pair box of zebrafish in model group significantly increased. After drug administration, the resident time and movement map in drug-pair box of zebrafish decreased. The verification results of qRT-PCR were consistent with the results of small RNA sequencing. Ninety-nine putative target genes of dremiR-723-5p that were common to all three target gene databases, which were mainly enriched in biological process, cell composition and molecular function, involved in the positive regulation of MAPK signaling pathway, lysosome, cytokine-cytokine receptor interaction, and apoptosis. Conclusion Morphine can increase the expression of dre-miR-723-5p in the zebrafish brain, which can be reversed by sinomenine, isorhynchophylline, and rhynchophylline treatment, and dre-miR-723-5p may participate in the mechanism underlying morphine-induced damage of brain.
