convalescence; sleep wake disorders; mood disorders; Shumian capsule rolled patients completed weeks of treatment and follow-up (Table 1) There were no significant differences between the two groups in terms of sex, age, body mass index, smoking, drinking, temperature, systolic blood pressure, diastolic blood pressure, respiration, pulse, waiting time for admission, length of stay, length of discharge, condition classification, CT (Pulmonary Computed Tomography), blood routine, comorbidity, and concomitant medication Obvious differences were observed between the two groups in terms of length of intervention and history of allergies (P = 0.023; P = 0.032) The average length of intervention was longer in group A than in group B, and more patients in group B had a history of allergies than those in group A (Table 2) INTRODUCTION Most patients with Corona Virus Disease 2019 (COVID-19), mainly in Hubei, have entered the convalescent period after treatment Although all the discharged patients have met the discharge criteria of improvement in lung inflammation and negative nucleic acid tests, a considerable number of patients still suffer from clinical discomfort and organ damage, such as cough, chest tightness, shortness of breath, increased heart rate, and fibrotic lesion changes in the lungs, as well as insomnia, anxiety, depression, and other symptoms of sleep disorders To utilize the advantage of Traditional Chinese Medicine (TCM) in "healing and prevention of recurrence," appropriate TCM treatment modalities can be selected and recommended to patients recovering from COVID-19 to help them recover as soon as possible and reduce the risk of recurrent COVID-19 infection In this study, combined with symptoms related to sleep mood disorders in patients with COVID-19 in the convalescence period, a randomized, double-blind, placebo-controlled, multicenter design was used to evaluate the therapeutic effects of using the TCM Shumian capsule (舒眠胶囊) as an intervention drug to improve insomnia, anxiety, depression, and other clinical symptoms of sleep disorders Diagnostic criteria The diagnostic criteria adopted were the criteria for release from isolation and discharge in the "COVID-19 Diagnostic and Treatment Protocol (Trial Version 6)": body temperature returns to normal for more than d; respiratory symptoms improve significantly; lung imaging shows significant absorption of inflammation; and two consecutive negative nucleic acid tests for respiratory pathogens (with a sampling interval of at least d), then the patient can be released from isolation or discharged and enter the convalescence period Inclusion criteria Patients who meet the diagnostic criteria for recovery from COVID-19; patients who have been cured and discharged from the hospital for > weeks; patients who are aged between 18 and 70 years; patients who have irritability, anxiety, poor sleep, and other sleep mood disorders as main clinical manifestations; patients who have two of these symptoms at the same time; patients who have a score of ≥ on the Visual Analogue Scale (VAS) for a single symptom; and patients who have signed the informed consent form MATERIALS AND METHODS Clinical characteristics Between April and May 2020, 200 patients with convalescent COVID-19 with symptoms of insomnia, anxiety, depression, and other sleep disorders were collected from three sites, and were divided into group A (experiment group, 100 cases) and group B (control group, 100 cases) using a random number table Two hundred patients were enrolled in the three sites, cases were eliminated, and 12 cases were dropped As a result, 197 patients were included in the FAS (Full Analysis Set, FAS), and 182 patients were included in the PPS (Per-Protocol Set, PPS) for statistical analysis All en- Exclusion criteria Patients who have difficulty taking oral medications due to underlying diseases;

after weeks of treatment, the differences in these symptoms between the two groups were statistically significant (P ≤ 0.001), and group A had better improvements in these symptoms than group B (Table 6) Comparison of the overall effective rate of TCM symptom improvement The overall effective rate of improvement in insomnia, Table TCM symptom scores (VAS) of the two groups Time Indicator Week Insomnia Anxiety Depression Week Insomnia Anxiety Depression Group A Group B Mean Min-Max 1-9 2-9 Median 6 mean±SD 5.0±1.8 6.0±1.9 Mean Min-Max 0-8 0-8 Median 4 mean±SD 3.0±2.2 4.0±2.1 Mean Min-Max 0-7 0-7 Median mean±SD 2.0±2.0 3.0±2.2 Mean Min-Max 0-9 1-10 Median mean±SD 4.0±2.1 5.0±2.4 Mean Min-Max 0-8 0-8 Median mean±SD 3.0±2.1 4.0±2.2 Mean Min-Max 0-7 0-8 Median 2 t value P value －0.936 0.351 －1.972 0.05 －1.842 0.067 －2.774 0.006 －2.795 0.006 －3.042 0.003 mean±SD 2.0±1.6 2.0±2.2 Notes: A: experimental group (Shumian capsule), B: control group (Shumian capsule Simulator) The course of intervention was weeks, capsule = 0.4 g, take capsules at a time, twice a day P value: comparison between group A and group B TCM: traditional Chinese Medicine;
