International Journal of Traditional Chinese Medicine 2009;31(6):524-525
Objective To observe the effect of treating neonatal jaundice with Qing Kai Ling injection plus photoradiation. Methods 583 cases were randomly recruited into a control group and a treatment group.342 cases in the treatment group received Qing Kai Ling injection plus photoradiation treatment, while 241 cases in the control group received only photoradiation treatment. TBIL, DBIL regression time of jaundice and symptom improvement were observed in both groups. Results After the treatment, TBIL and DBIL's level in the treatment group was lower than the control group (P< 0.05) . symptoms improving in the treatment group was also significantly better (P=0.0087) . The recovery time for the treatment group was shorter than the control group (P= 0.0068). Conclusion Qing Kai Ling injection plus photoradiation is good in treating neonatal jaundice.

Chinese Journal of Dermatology 2003;0(07):-
Objective To investigate peripheral blood dendritic cells (DC) responding to herpesvirus infection in the patients with recurrent genital herpes and the expression of immune molecules on mature DC induced by the cytokines in vitro. Methods Using three-color flow cytometry, we studied the phenotype expression of CD11c, CD123, CDla, CD80, CD86, CD40 and CD83 on the two subsets of DC(CD11c+DC and CD123+DC) in peripheral blood. The monocytes isolated from the blood were cultured with recombinant human granulocyte-macrophage colony stimulating factor (GM-CSF), interleukin-4 (IL-4) and tumor necrosis factor alpha (TNF-?) from 20 patients with recurrent genital herpes (RGH) and 18 healthy controls. Results The number of CD11c+ DC in the peripheral blood increased significantly in the peripheral blood cells of RGH patients (2.54% ? 1.19%) in comparison with that of healthy controls (1.77% ? 0.83%) (P 0.05). Conclusions Peripheral blood CD11c+DC activated by uptaking viral antigens in the patients with RGH results in a high level expression of co-stimulatory molecules on DC and enhance antigen-presenting functions, which is essential for intiating antiviral immune response directly by T lymphocytes.
5.Quantification of peripheral blood HPV16 antigen-specific CD8~+ cytotoxic T cells in patients with condyloma acuminatum
Chinese Journal of Dermatology 1994;0(05):-
Objective To study the roles of phenotype switch of HPV16 antigen-specific CD8~+ cy- totoxic T cells (CTLs) in peripheral blood as well as the cellular immune response of human T lympho- cytes to viral peptides in the pathogenesis of condyloma acuminatum.Methods HPV16E7~(11-20) (HLA-A*0201/YMLDLQPETT) antigen-specific CTLs were stained with fluorescent-labeled recombinant MHC class I-peptide pentamer complex,and co-stained with CD69 (activated CTL) and CD45RO (mem- ory CTL) surface markers,in peripheral blood from 10 patients with condyloma acuminatum and 15 normal controls.The CTLs were quantitated by flow cytometric analysis.Meanwhile,peripheral blood mononuclear cells of 13 healthy donors were incubated for 7 days with HPV16E7_(11-20) peptide,recombinant human inter- leukin 7 and interleukin 2 to yield antigen-specific CD8~+ CTLs and their other surface markers.An irrelevant peptide,HBVcore_(18-27) (FLPSDFFPSV),was used as an isotype control.Results The percentages of periph- eral blood HPV16E7 antigen-specific CD8~+CTLs,activated CTLs and memory CTLs of total CD8~+ T cells were increased significantly in patients with condyloma acuminatum (0.76%?0.43%,0.36%?0.20%,and 0.33%?0.15%,respectively) than those in normal controls (0.24%?0.07%,0.17%?0.05% and 0.15%?0.06%,respectively) (P<0.01,P<0.05,and P<0.01,respectively).For T cells in vitro stimulated with viral peptide for 7 days,the percentages of peptide-specific CD8~+ CTLs,activated CTLs and memory CTLs were significantly higher (0.75%?0.16%,0.35%?0.15% and 0.33%?0.18%,respective- ly) in comparison with those in non-stimulated group (0.24%?0.06%,0.16%?0.03% and 0.13%?0.04%,respectively ) (P<0.001,P<0.01 and P<0.01,respectively ).Conclusions These results,in vivo and in vitro,demonstrate that the proliferation of CD8~+ T cell clones induced by HPV infection could generate antigen-specific CD8~+ CTLs,causing a highly efficient and specific killing of viral-infected target cells directly,which may play an important role in antiviral T cell-mediated immune response.

Objective To investigate the possible roles of cellular immunosuppression induced by phenotypic and functional changes of peripheral CD4+CD25+ regulatory T cells (Tregs) in the pathogenesis of condylomata acuminata. Methods Three-color flow cytometry was performed to examine the expression of transcription factor Foxp3 in, along with several inhibitory membrane molecules, i.e. cytotoxic T lympho-cyte associated antigen-4 (CTLA-4), glucocorticoid-induced TNF receptor family-related gene (GITR) and programmed death-1 (PD-1) on peripheral CD4+CD25+ T cells from 46 patients with condylomata acuminata and 43 normal human controls. Meanwhile, high purity of CD4+CD25+ T cells were isolated from peripheral blood using imrnunomagnetic beads, and stimulated to produce intracellular suppressor cytokines such as interleukin-10 (IL-10) and transforming growth factor-beta (TGF-beta), which were detected by flow tyro-metric analysis. Results The number of peripheral CD4+CD25+ Foxp3+ Tregs increased significantly in patients with condylomata acuminata than that in the normal controls (7.37% ± 2.43% vs 5.96% ± 2.09%,P < 0.001). The expressions of CTLA-4 and PD-1 were 1.86% ± 1.13% and 2.41% ± 1.12%, respectively,in the patients, which were significantly higher than those in the normal controls(1.36% ± 0.90% and 1.70%± 0.97%, P < 0.05 and 0.01, respectively). The number of TGF-beta-positive CD4+CD25+ T ceils from peripheral blood were increased in patients than that in, the controls (1.57% ± 0.91% vs 0.78% ± 0.24%, P <0.001). Conclusions Human papillomavirus infection can induce the activation and proliferation of CD4+CD25+ Tregs, enhance the expression of negative costimulatory molecules and secretion of suppressor cytokines, and inhibit antiviral immune response through multiple mechanisms.

Although the concept of united airway disease has been widely accepted, most scholars emphasize only the effect of rhino-sinusitis while ignoring the pharyngeal factors to the lower airway, especially to the allergic pharyngitis (AP), which still lacks enough awareness. First of all, absence of unified diagnostic standard leads to the lack of epidemiological data, which, results in doctors' personal experience but no guideline in treatments. In addition, it is still not clear that the role of AP in the allergic airway diseases and its relationship with asthma. However, the number of patients with AP has been increasing obviously in daily clinic practice. Combined with the previous observation, this paper does a systematic review about the clinical problems of AP, expecting to give a hand to the clinical diagnosis and treatment of AP.
