Methods: Monocytes were infected by HSV-2 (333Strain). Culture supernatants were collected at 1, 3,5, 7 days post-infection. The levels of TNF-α, IL-6were measured by enzyme-linked immunosorbent as-say (ELISA). Results: The levels of TNF-α secretion by mono-cytes significantly decreased on first day post-infection. The levels of IL-6 significantly decreasedon first and third days post-infection, and then gradu-ally increased to the control on seventh day post-infection. Conclusions: TNF-α and IL-6 production by mono-cytes was inhibited during HSV-2 infection. The pro-duction of cytokines may play an important role inherpes simplex viurs-2 pathogenicity and immunity.展开更多

Culture cells were collected 1, 3, 5 and 7days after infection. The levels of expression of HLAclass II antigen were measured by using alkaline phos-phatase antialkaline phosphatase method (APAAP).Results: The levels of the expression of HLA class IIantigen on monocytes significantly decreased on thefirst day of post-infection, and then gradually returnedto levels found in the controls by the 7th day post-infection.Conclusion: HLA class II antigen expression onmonocytes was inhibited with HSV-2 infection, whichmight be one means of virus escape at an early phase.The expression of HLA class II antigen may play animportant role in herpes simplex viurs-2 pathogenic-ity and immunity.展开更多

Methods: Immunofluorescent staining or cell surface antigenand intracellular cytokines(IL-2、IL-4、IL-12、IFN-r)inperipheral blood from 20 RGH patients and 10 controls wereanalyzed using flow cytometric techniques. Results: RGH patients had signiflcantly lower levels ofCD3^+T cells, CD4^+T cells and CD4^+ T/ CD8^+ T cells ratiocompared to control levels (P<0.001), and IL-2-producing,IFN-r-producing and IL-12-producing T cells were increasedin RGH patients (CD4^+T: P<0.001, CD8^+T: P<0.05respectively), whereas IL-4-producing T cells were increased inRGH patients compared to controls (CD4^+T: P<0.05; CD8^+T:P<0.001 respectively). Conclusions: RGH patients have T lymphocyte subsetvariations and Th1/Th2 cytokine changes. The increase in Th2cells Th1/Th2 imbalance may have important implications forRGH pathogenesis.展开更多

Methods: Thirty-six cases of atypical GH were diagnosedclinically, and their case histories, symptoms and signs wererecorded in detail and followed up. Polymerase chain reaction(PCR) was adopted for testing HSV2-DNA with cotton-tippedswabs. Enzyme-linked immuno sorbent assay (ELISA) forserum anti-HSV2-IgM was done to establish a definitivediagnosis. Other diagnoses were excluded at the same time bytesting for related pathogens including fungi, Chlamydia,Mycoplasma, Treponema pallidum, gonococci, Trichomonas,etc. Results: The main clinical manifestations of atypical GHwere: (1) small genital ulcers; (2) inflammation of urethralmeatus; (3) nonspecific genital erythema; (4) papuloid noduleson the glands; (5) nonspecific vaginitis. Twenty-three cases(64%) tested by PCR were HSV2-DNA sera-positive, and 36cases (100%) anti-HSV2-1gM sera-positive by ELISA. Conclusion: atypical HSV is difficult to be dinosed. But the combination of PCR and ELIAS will be helpful to thediagnosis of atypical HSV.展开更多
