Objective To observe effects of acupoint sticking of Migudan on BGP and Hyp in the patients of primary osteoporosis. Methods By computer random number generating method, the patients were randomly divided into a treatment group treated with acupoint sticking of Migudan, and a control group treated with Gaitianli, 48 cases in each group. Changes of their BGP and Hyp after treatment were investigated. Results Acupoint sticking of Migudan could increase significantly BGP of serum in the patients of primary osteoporosis as compared with the control group (P

Objective To investigate the effect of acupuncture plus Chinese herbal medication on plasma endothelin (ET-1) and calcitonin gene-related peptide (CGRP) in child patients with mesenteric lymphadenitis.Methods One hundred and eighty child patients with mesenteric lymphadenitis were randomly allocated to groups A, B and C, 60 cases each. Group A received acupuncture at Zusanli and pricking Sifeng points plus oral administration of Wudang Babao Zijinding; group B, oral administration of amoxicillin and clavulanate potassium granules; group C, oral administration of Wudang Babao Zijinding alone. ET-1 and CGRP contents were measured in the three groups before and after treatment.Results There were statistically significant pre-/post-treatment differences in ET-1 and CGRP contents in group A (P<0.01). There were statistically significant post-treatment differences in ET-1 and CGRP contents between group A and group B or C (P<0.01).Conclusions Acupuncture plus Chinese herbal medication is an effective way to treat mesenteric lymphadenitis in children. It can regulate ET-1 and CGRP in the patients.

OBJECTIVETo investigate the effect and mechanism of B16F10-ESAT-6-gpi/IL-21 tumor cell vaccine on pulmonary metastasis in mouse model of melanoma.

METHODSTwelve 8-week old female C57BL/6 mice were used in this study. The mice were injected with wild-type B16F10 cells through tail vein after immunization with B16F10-ESAT-6-gpi/IL-21 tumor cell vaccine, and the pulmonary metastasis was observed. The CD4(+) and CD8(+) T cells were isolated by magnetic activated cell sorting, and then used for the detection of CFSE/7-AAD cytotoxicity by flow cytometry. Serum from the mice immunized with tumor-cell vaccine was used to detect IFN-γ expression by ELISA. The expression of TGF-β2, ZEB1, E-cadherin, and N-cadherin of tumor tissues was detected by RT-PCR and immunofluorescence, respectively.

RESULTSThe mice vaccinated with B16F10-ESAT-6-gpi/IL-21 had significantly fewer nodules in the lung and lower lung weight [(285.8 ± 19.01) mg vs. (406.3 ± 27.12) mg], with lower levels of TGF-β2, ZEB1 and N-cadherin proteins but higher level of E-cadherin protein within the tumor tissue, as compared with the control mice. Meanwhile, the immunized mice had significantly increased CD8(+) T cell killing activity [(42.62 ± 3.465)% vs. (22.29 ± 1.804)%] and IFN-γ expression level [(55.200 ± 7.173) pg/ml vs. (6.435 ± 1.339) pg/ml] over the control mice.

CONCLUSIONSThe B16F10-ESAT-6-gpi/IL-21 vaccine can inhibit the metastasis of melanoma in the lung in vaccinated melanoma-bearing mice. This inhibitory effect is associated with CD8(+) T cell immune response and a higher level of IFN-γ, which may influence on the mesenchymal-epithelial transition of tumor cells.
