Semiquantitative analyses of CD4+ and IL-17+ cells before (M0) and after (M8) cART.

Slides of colon tissues were scored as “−” (less than 3 positive cells); “+” (3–10 positive cells); “++” (20–40 positive cells) and “+++” (more than 50 positive cells). Bold: samples in which both IL-17+ and CD4+ cells were increased at M8; Black: samples in which only IL-17+ cells were increased at M8; Gray: samples in which neither IL-17+ nor CD4+ cells were increased at M8.Semiquantitative analyses of CD4+ and IL-17+ cells before (M0) and after (M8) cART.结肠组织切片的评分规则如下：“−”代表阳性细胞数少于3个；“+”代表阳性细胞数为3~10个；“++”代表阳性细胞数为20~40个；“+++”代表阳性细胞数多于50个。其中，加粗标记的样本为M8时间点同时出现白细胞介素17阳性（IL-17+）细胞与CD4阳性（CD4+）细胞增多的样本；黑色标记的样本为仅在M8时间点出现白细胞介素17阳性（IL-17+）细胞增多的样本；灰色标记的样本为M8时间点两类细胞均未出现增多的样本。对接受联合抗逆转录病毒治疗（combined antiretroviral therapy, cART）前（M0）及治疗后8周（M8）的CD4阳性（CD4+）细胞与白细胞介素17阳性（IL-17+）细胞进行半定量分析。
