ABSTRACT

Based on the theory of ascending and descending of center qi, it is believed that yang deficiency and water dampness, as well as abnormal circulation of center qi, are the core pathogenesis of psoriasis. The common pathogenic evolution of psoriasis includes wood constraint and blood stagnation, lung metal fluid exhaustion. In the later stage of psoriasis, a mixture of deficiency and excess patterns, as well as cold and heat in complexity, are often observed. Treatment focuses on warming yang and resolving dampness to restore proper qi ascending and descending, and the therapeutic formulas such as Ganjiang Lingzhu Decoction (甘姜苓术汤), Zexie Decoction (泽泻汤), Zhenwu Decoction (真武汤), and Linggui Zhugan Decoction (苓桂术甘汤) are suggested based on the nature and location of the disease. To unblock the qi movement through discharging the liver and rectifying the lung, Xiaochaihu Decoction (小柴胡汤) and Danzhi Xiaoyao Powder (丹栀逍遥散) are commonly used as the foundation with modifications. To balance yin and yang through clearing the heart and nourishing the kidneys, a self-designed Changzhong Decoction (畅中汤) is utilized. Following the theory of ascending and descending of center qi, it is suggested to combine cold and warm medicinals and mediate the center earth, so as to promote the circulation of the center qi, restore the clear and the turbid, and keep four-dimensional smooth flow of qi, providing a reference for traditional Chinese medicine treatment for psoriasis.

ABSTRACT

Objective To explore the level of Th2 type cytokines including IL-4, IL-10 and IL-13, and the immunoreg-ulation of cytokines in patients with neurocysticercosis. Methods Lymphocytes in patients with neurocysticercosis were separated from the blood sample with density gradient centrifugation and the total RNA was extracted by guanidine isothiocynate method. cDNA was synthesized by reversed transcription reaction. The target gene was then amplified by PCR. The PCR products were analyzed by electrophoresis. Results Results of RT-PCR showed that cytokines mRNA in lymphocytes of peripheral blcod were detected in 27 patients with neurocysticercosis but not in the other 3 cases. Among the positive cases, mRNA of IL-4, IL-10 and IL-13 was detected in 16, 17 and 14 cases respectively and mRNA of IL-4, IL-10 and/or IL-13 was detected in all the 27 cases. In the detection of lymphocytes in peripheral blcod of 10 healthy subjects, expression of IL-4 and IL-10 was found in only one case at low level. Conclusion The study revealed that Th2 associated cytokines were expressed at high level and the humoral immunocompetence was relatively strong in patients with neurocysticercosis.

ABSTRACT

Objective To study the protective effect of ROP2 nuclei acid vaccine in mice.Methods Forty-two BALB/c mice were divided into three groups.Each mouse in experiment group was injected with 50 ?g recombinant plasmid pc-DNA3-ROP2 through musculus quadriceps fexoris.In control groups,each mouse was injected with 50 ?g blank plasmid pc-DNA3 and with 50 ?l PBS respectively.All mice were immunized for three times with an interval of three weeks.The volume was doubled for the final injection in the two plasmid groups.Blood,spleens and lymph nodes of 4 mice in each group were taken for the detection of CD4+,CD8+ T cells and cytokines 2 weeks after the final immunization.The rest mice in 3 groups were challenged with 500 tachyzoites of Toxoplasm gondii RH strain for further observation.Results The vaccine induced strong cellular and humoral immune response.The titer of antibody in serum was high after inoculation and recognized ROP2 protein antigen expressed in vitro.The lymphocyte phenotype was analyzed.CD4+ T cells proliferated sharply(69.5?3.4)%,and the ratio of CD4+/CD8+ increased considerably by(4.69?1.32)%(P
