Detailed Description
-----------------
Patients were assigned to Four sessions of electroacupuncture(EA) at the CV12, ST36, CV12+ST36 acupoints or antiemetic therapy over 5 days. primary and secondary outcomes and Adverse Eventswill be assessed.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Single point CV12<br>choose single point:Zhongwan(CV12).Zhongwan(CV12):On the upper abdomen, 4 B-cun superior to the centre of the umbilicus, on the anterior median line.Manipulating until achieving a de Qi sensation,then the needle is connected through a electro-acupuncture apparatus,the positive pole is linked to the needle, and the reference pole is located near the acupoint about 1cm with a paster. Frequency 10Hz,the intensity of stimulation is adjusted according to the patient's tolerance, and the electric current is less than 10mA.The operation lasts for 30 min. The treatmeat is scheduled to occur within 30min-60min before chemotherapy infusion for 4 days. Received routine antiemetic treatment. | Other: single point Zhongwan(CV12) plus antiemetic drug<br>* All participants were supine in the hospital bed. A disposable sterile acupuncture needle (ø 0.30 × 40 mm, Hwato) was inserted vertically at approximately 20-30 mm until De Qi (sensation of soreness, numbness, distension, etc. around the acupoint) was reported by the participants. Then, the needle handle was clamped via a metal clip to connect to the positive electrode of the electric acupuncture apparatus (Huatuo, SDZ-V model, Suzhou Medical Appliance). Another reference electrode was placed 1 cm above the CV12 acupoints of the stimulation point, where no acupoints or meridians passed through. A dilatational wave at a frequency of 2/10 Hz and a current intensity at the highest level tolerated by the patient, with a maximum intensity no more than 10 mA, were used to deliver the EA stimulation. People in the intervention groups were offered a standardized 30-minute EA session once daily from the 1st day of the four-day chemotherapy cycle.<br>|
| Experimental: Single point ST36<br>choose another single point Zusanli（ST36）.Zusanli(ST36):On the anterior aspect of the leg, on the line connecting ST35 with ST41, 3 B-cun inferior to ST35，located on the tibialis anterior muscle..Manipulating until achieving a de Qi sensation, then the needle is connected through a electro-acupuncture apparatus,the positive pole is linked to the needle, and the reference pole is located near the acupoint about 1cm with a paster. Frequency 10Hz,the intensity of stimulation is adjusted according to the patient's tolerance, and the electric current is less than 10mA.The operation lasts for 30 min. The treatmeat is scheduled to occur within 30min-60min before chemotherapy infusion for 4 days. Received routine antiemetic treatment. | Other: single point Zusanli(ST36) plus antiemetic drug<br>* A disposable sterile acupuncture needle (ø 0.30 × 40 mm, Hwato) was inserted vertically at approximately 20-30 mm until De Qi (sensation of soreness, numbness, distension, etc. around the acupoint) was reported by the participants. Then, the needle handle was clamped via a metal clip to connect to the positive electrode of the electric acupuncture apparatus (Huatuo, SDZ-V model, Suzhou Medical Appliance). Another reference electrode was placed 1cm below ST36 acupoints of the stimulation point, respectively, where no acupoints or meridians passed through. A dilatational wave at a frequency of 2/10 Hz and a current intensity at the highest level tolerated by the patient, with a maximum intensity no more than 10 mA, were used to deliver the EA stimulation. People in the intervention groups were offered a standardized 30-minute EA session once daily from the 1st day of the four-day chemotherapy cycle.<br>|
| Experimental: ST36+CV12 acupoints<br>Choose both Zusanli(ST36) and Zhongwan（CV12）.Manipulating until achieving a de Qi sensation, then the needle is connected through a electro-acupuncture apparatus,the positive pole is linked to the needle, and the reference pole is located near the acupoint about 1cm with a paster. Frequency 10Hz,the intensity of stimulation is adjusted according to the patient's tolerance, and the electric current is less than 10mA.The operation lasts for 30 min. The treatmeat is scheduled to occur within 30min-60min before chemotherapy infusion for 4 days. Received routine antiemetic treatment. | Other: Zusanli(ST36)and Zhongwan(CV12) plus antiemetic drug<br>* Stimulating both Zusanli(ST36)and Zhongwan(CV12)<br>|
| Active Comparator: only antiemetics<br>The control group will receive standard antiemetics alone. Standard antiemetics for all groups are based on American Society of Clinical Oncology clinical practice guideline. 5-hydroxytryptamine-3 (5-HT3) antagonist (Ramosetron , Tropisetron)and dexamethasone are supplied from the first day of chemtherapy,and lasting for 3-5days. If nausea and/or vomiting is persistent and failed to respond to the antiemetic treatment , based on the experience of each clinician, the other advanced 5-HT3 antagonist or a neurokinin 1 antagonist(NK-1) will be chosen. | Drug: only antiemetic drug<br>* received routine antiemetic treatment<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants With Nausea | Percentage of participants with nausea was assessed by visual analog scale (VAS) ranging from 0 (no nausea) to 10 (worst nausea). A score of 0 means no nausea for a portion of the patient's assessment. | 5 days | 
| Number of Times Vomiting Occurs After Chemotherapy | The number of times vomiting occurs after chemotherapy for each participant during 0-120 hours. The evaluator completed daily diaries for each time point. | 5 days | 
| Rhodes Index of Nausea, Vomiting and Retching | The RINVR scale has 8 items . The scale divides the occurrence of nausea , vomiting , and retching within 12 hours of tumor chemotherapy patients into 5 grades , which are scored from 0 to 4 points . The lower the score , the better . The RINVR scale can be divided into three dimensions : symptom experience time , symptom frequency and symptom severity . | 5 days | 
| Percentage of Participants With Nausea and Number of Times of Vomiting Occurs After Chemotherapy | Rhodes Index of Nausea, Vomiting and Retching was replaced by percentage of participants with nausea (assessed by VAS) and number of times of vomiting occurs which were recorded in the first and second primary outcome. | 5 days | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Grading of Constipation and Diarrhea | The grading of constipation and diarrhea.We deleted this evaluation method due to weak correlation. | 5 days | 
| Electrogastrogram | We deleted this evaluation method due to weak correlation. | 5 days | 
| the Assessment of Quality of Life | Assessed by the Functional Assessment of Cancer Treatment-General (FACT-G) .The FACT-G includes 27 items and is divided among 4 subscales: physical well-being (PWB), functional well-being (FWB), social/family well-being (SWB), and emotional well-being (EWB). The total FACT-G score ranges from 0 to 108 and is calculated by the sum of the subscales, with higher scores indicating greater functional status | 5 days | 
| the Assessment of Anxiety and Depression | Assessed by Hospital Anxiety and Depression Scale (HADS scale). It includes fourteen items, seven of which assess anxiety and the other seven assess depression (30). The total scores range from 0 to 21 for depression and anxiety, respectively, with higher scores indicating more depression and anxiety. | 5 days |
