Embodiment 1

[0031] Example 1 Targeting CD4 T lymphocytes in the treatment of primary cutaneous T cell lymphoma

[0032] (1) Animal model establishment and grouping

[0033] Mouse primary cutaneous T-cell lymphoma model, select adult BABL / c mice, male, 18-22g. During the experiment, take the well-grown tumor tissue, cut it into pieces, grind it, filter it, and dilute it with sterile normal saline at a ratio of 1:3 to make a tumor cell suspension, and inoculate 0.2ml of the tumor cell suspension on the back of the armpit of each mouse . The next day after inoculation, the animals were randomly divided into 8 groups, namely: (1) negative control group (normal saline group, NS), (2) chlorogenic acid administration group (CHA, 5 mg / kg), (3) Chlorogenic acid administration group (CHA, 10mg / kg), (4) Chlorogenic acid administration group (CHA, 20mg / kg), (5) Interferon administration group (IFN-γ), (6) Chlorogen Acid and interferon administration group (CHA+IFN-γ, 5mg / kg), (7) Chlorogenic acid ...

[0046] Example 2 Targeting CD8 T lymphocytes in the treatment of primary cutaneous T cell lymphoma

[0047] (1) Animal model establishment and grouping

[0048] Mouse primary cutaneous T-cell lymphoma model, select adult BABL / c mice, male, 18-22g. During the experiment, take the well-grown tumor tissue, cut it into pieces, grind it, filter it, and dilute it with sterile normal saline at a ratio of 1:3 to make a tumor cell suspension, and inoculate 0.2ml of the tumor cell suspension on the back of the armpit of each mouse .

Embodiment 3

[0061] Example 3 Experiment of chlorogenic acid on tumor suppression rate of primary cutaneous T-cell lymphoma

[0062] (1) Animal model establishment and grouping

[0063] Mouse primary cutaneous T-cell lymphoma model, select adult BABL / c mice, male, 18-22g. During the experiment, take well-grown tumor tissue, cut it into pieces, grind it, filter it, and dilute it with sterile normal saline at a ratio of 1:3 to make a tumor cell suspension, and inoculate 0.2ml of the tumor cell suspension on the back of each mouse’s armpit . On the second day after inoculation, the animals were randomly divided into 8 groups, namely: (1) negative control group (normal saline group, NS), (2) chlorogenic acid administration group (CHA, 5 mg / kg), (3) Chlorogenic acid administration group (CHA, 10mg / kg), (4) Chlorogenic acid administration group (CHA, 20mg / kg), (5) Interferon administration group (IFN-γ), (6) Chlorogen Acid and interferon administration group (CHA+IFN-γ, 5mg / kg), (7) Chlorogen...

Abstract

The invention aims to provide an application of chlorogenic acid in preparing drugs for prevention and treatment of primary cutaneous T-cell lymphoma. Experiments show that the chlorogenic acid can activate CD4 T-lymphocytes and CD8 T-lymphocytes, and prevent and treat primary cutaneous T-cell lymphoma by taking the CD4 T-lymphocytes and the CD8 T-lymphocytes as targets. According to the invention, the chlorogenic acid is adopted for promoting the proliferation of T-lymphocytes of a body and activating the T-lymphocytes so as to achieve the purpose of treating primary cutaneous T-cell lymphoma. Meanwhile, the chlorogenic acid also can inhibit the proliferation of primary cutaneous T-cell lymphoma cells, and the inhibition effect of the chlorogenic acid is similar to the inhibition effect of interferon.

Description

technical field [0001] The invention relates to the field of biomedicine, especially the field of treatment of primary cutaneous T-cell lymphoma, in particular the use of chlorogenic acid in the preparation of medicines for preventing and treating primary cutaneous T-cell lymphoma. Background technique [0002] Primary cutaneous T cell lymphoma (CTCL), formerly known as granuloma fungoid, is a cutaneous primary lymphoma. As a group of lymphoproliferative diseases with obvious heterogeneity, it lacks a standardized treatment plan. [0003] In the early stage of its onset, it is mainly to enhance the patient's immunity and local treatment, such as interferon, BCG or transfer factor, etc.; local treatment can be external application of nitrogen mustard or aromatic retinoic acid, electron beam irradiation, X-rays, and photochemotherapy etc. have a certain curative effect. At present, no new chemotherapy drugs and targeted therapy drugs have been reported for the treatment of ...
