Disseminated cryptococcal lymphadenitis with negative latex agglutination test / 中华医学杂志(英文版)

We reported an unusual case of disseminated cryptococcal lymphadenitis in an immunocompetent host who presented with fever and lymphadenopathy, which were the only two symptoms and signs. Latex agglutination test of serum and cerebrospinal fluid (CSF) were negative, while lymph node biopsy showed Cryptococcus neoformans. A diagnosis of disseminated cryptococcal lymphadenitis was made. Then the patient was treated with amphotericin B for 15 days as initial therapy and itraconazole for 6 months as maintenance therapy respectively. The patient received re-examination per 6 months and was followed up for 2 years. Swollen lymph nodes diminished gradually, and no fever or other symptoms were found. Latex agglutination test of serum and CSF were negative throughout the follow-up period, and anti-HIV, syphilis and tuberculosis antibody were all negative.

Xiaoyin recipe ( ) for psoriasis induces a Th1/Th2 balance drift toward Th2 in peripheral blood mononuclear cells of experimental autoimmune thyroiditis rats / 中国结合医学杂志

<p><b>OBJECTIVE</b>To explore the regulatory mechanism of Xiaoyin Recipe () on the T helper 1/T helper 2 (Th1/Th2) immune balance.</p><p><b>METHODS</b>Thirty-six experimental animals were divided into three groups, 12 rats in each group: blank control group (B group), negative control group (N group), and Xiaoyin Recipe treatment group (T group). The latter two groups received immunization of experimental autoimmune thyroiditis (EAT), and T group were treated with Xiaoyin Recipe for a month. Then, the expression of Th1-Th2-related genes in peripheral blood mononuclear cells (PBMCs) were screened with Oligo GEArray Rat Th1-Th2-Th3 Microarray. The expressions of tumor necrosis factor-α (TNF-α), interleukin-10 (IL-10), T-box expressed in T-cells (T-bet), and GATA-binding protein-3 (GATA-3) were detected by real-time polymerase chain reaction (RT-PCR).</p><p><b>RESULTS</b>Gene array screening showed that compared to N group, in T group after Xiaoyin Recipe treatment, 3 genes were upregulated in EAT rats, including interleukin-27 receptor alpha (IL-27rα), glomulin (Glmn), and GATA-3, while 38 genes were downregulated, such as CD28, IL-18, signal transducer, and activator of transcription 1 (STAT1), T-bet, TNF receptor superfamily member 4 (TNFRSF4), TNF ligand superfamily member 5 (TNFSF5), and TNF receptor superfamily member 5 (TNFRSF5). While RT-PCR showed that there was an increased level of TNF-α mRNA (P<0.01), an elevated ratio of T-bet/GATA-3, and a decreased level of IL-10 mRNA in PBMC of N and T group compared to B group (P <0.01); and after treatment with Xiaoyin Recipe, IL-10 mRNA level increased (P <0.01), while TNF-α mRNA level and T-bet/GATA-3 ratio decreased in T group compared to N group (P <0.01).</p><p><b>CONCLUSION</b>Xiaoyin Recipe for psoriasis could induce a Th1/Th2 balance drift toward Th2 in PBMC of EAT rats and thus improve the conditions.</p>
