Study Overview
Brief Summary
The purpose of this experiment is to evaluate the efficacy of supplemental health food Grape King Hericium erinaceus Mycelium Capsules and Grape King Probiotic Capsules in improving physical and psychological symptoms, blood oxidative stress and inflammation indicators in women with premenstrual syndrome.
Detailed Description
This study was a randomized, double-blinded and placebo-controlled research. This study was approved by the Institutional Review Board of the Chung Shan Medical University Hospital and all Participants signed the written informed consent to participate in the study.
Participants met the inclusion criteria, ie: age 20~45 yr and a regular menstrual cycle (21~35 days per cycle) were recruited through advertisements posted around the Chun Shan Medical university campus. In screening phase of this study, affective and one somatic symptom in before onset of menstruation in two consecutive cycles and was not affected by depression or anxiety disorder, she is examined by the Attending Physician of the Obstetrics and Gynecology Department to diagnosed a patient with premenstrual syndrome. In the intervention phase of this study, 105 eligible participant were randomly divided into intervention (Grape King Hericium erinaceus Mycelium Capsules and Grape King Probiotic Capsules) and control groups (n=35/group). Both subjects and researchers were blind to the treatment assignment until the statistical analysis was completed. All participants received two oral capsules containing Hericium erinaceus Mycelium, probiotics or placebo every day for the 3 months. The capsules of intervention supplementations and placebo provided by Grape King Biotechnology Inc in identical appearance and package to guarantee the blindness.
Data collection A validated semi-quantitative Food Frequency Questionnaire was used to obtain daily nutritional values of participants. To assess the symptoms of PMS, all subjects need to fill out daily record of severity of problems on a daily basis in the 3 months of intervention period and 6 months after the intervention. In the 0, 1, 3 months of intervention, the anthropometric parameters and body composition were measured by using bioelectrical impedance analysis method ( MC-980 MA PLUS, TANITA BIA Technology). In the 0, 1, 3 months of intervention, venous blood samples were taken from all subjects for measuring the marks of oxidative stress and inflammation.

Masking Description
Both subjects and researchers were blind to the treatment assignment until the statistical analysis was completed. All the subjects were randomly divided into placebo group and two intervention groups (i.e. supplementation with Grape King Hericium erinaceus Mycelium Capsules and Grape King Probiotic Capsules) by using Excel to generate random numbers.

Outcomes
Primary Outcomes
The changes from baseline of Daily record of severity of problems
Time Frame: All eligible subjects recorded their symptoms by questionnaire of daily record of severity of problems at every day of 3 consecutive menstrual cycles during the intervention period and the 3rd menstrual cycles at the end of intervention.
This questionnaire of daily record of severity of problems were using to determine the severity of PMS including mood, physical and behavioral symptoms and characteristics. There are21 items grouped into 11 domains. Additional questions asked about quality of life and satisfaction of self-health. The levels of severity on this form are: 1- Not at all, 2- Minimal to Mild, 3-Moderate, 4- Severe. During each month of the intervention period and the 3rd menstrual cycles at the end of intervention, the changes of the total scores of menstrual cycles compared with the baseline in each groups were analyzed.
The differences from control of Daily record of severity of problems

Secondary Outcomes
- The differences from baseline of high-sensitivity C-reactive protein(In the 1st data of menstruation of the beginning, 1st and 3rd months of intervention, the blood of all eligible subjects were collected to measure the concentration of high-sensitivity C-reactive protein.)

- The differences from control of high-sensitivity TNF-a(In the 1st data of menstruation of the beginning, 1st and 3rd months of intervention, the blood of all eligible subjects were collected to measure the concentration of TNF-a.)
- The differences from control of total antioxidant capacity(In the 1st data of menstruation of the beginning, 1st and 3rd months of intervention, the blood of all eligible subjects were collected to measure the concentration of total antioxidant capacity.)
- The differences from control of high-sensitivity interleukin-1(In the 1st data of menstruation of the beginning, 1st and 3rd months of intervention, the blood of all eligible subjects were collected to measure the concentration of interleukin-1.)
- The differences from baseline of malondialdehyde(In the 1st data of menstruation of the beginning, 1st and 3rd months of intervention, the blood of all eligible subjects were collected to measure the concentration of malondialdehyde.)
- The differences from control of high-sensitivity C-reactive protein(In the 1st data of menstruation of the beginning, 1st and 3rd months of intervention, the blood of all eligible subjects were collected to measure the concentration of high-sensitivity C-reactive protein.)
