The randomized clinical trial included subjects (n =216) will be randomly divided into experimental (n = 162) and control groups (n =54) according to a random number table. Patients in the experimental group will receive Huaiqihuang Granule . Patients in the control group will receive placebo a placebo-controlled designed is used for this study. To minimize the risks, treatment stopping rules and subsequent measures are established for subjects whose disease under study become worsening during the study. Subjects receiving placebo treatment will switch to investigational drug after Week 24 to reduce the risk of lack of efficacy by placebo.
