采用碱性磷酸酶－抗碱性磷酸酶技术及３Ｈ－ＴｄＲ掺入法，测定Ｔ细胞亚群、淋巴细胞转化率及γ－干扰素表达细胞等指标，以评价清温冲剂对呼吸道病毒感染小儿免疫功能的作用。结果显示，清温冲剂组在治疗第４天外周血Ｔ３、Ｔ４亚群的数值及Ｔ４／Ｔ８比例与对照组比较无明显差异（Ｐ＞０．０５），但γ－干扰素表达细胞、淋巴细胞刺激指数及分泌性ＩｇＡ均明显增高，与对照组比较差异显著（Ｐ＜０．０５）。表明清温冲剂能促进和调节机体的免疫功能。
Alkaline phosphatase-anti-alkaline phosphatase technology and 3H-TdR incorporation assay were used to determine indicators of T cell subsets, lymphocyte transformation rate, and γ-interferon-expressing cells to evaluate Qingwen Granules for respiratory viral infections in children The role of immune function. The results showed that the T3 and T4 subsets and T4/T8 ratio in peripheral blood of Qingwen Granules group had no significant difference compared with the control group on the 4th day of treatment (P>0.05), but γ-interferon-expressing cells and lymph The cell stimulation index and secretory IgA were significantly increased, and they were significantly different from the control group (P<0.05). It shows that Qingwen Granule can promote and regulate the body’s immune function.
