We have been utilized acupuncture and moxibustion in our department of internal medicine at Meiji University of Integrative Medicine since its investment in 1987. In the department, various kinds of symptoms in the field of internal medicine have been managed with acupuncture and moxibustion. In this article, I would like to introduce our activities regarding acupuncture treatment in the department of internal medicine and some remarkable results of our clinical studies which evaluated effects of acupuncture and moxibustion as well as relationship between acupuncture therapists and the staff of our department. In the field of respiratory disorders such as COPD or bronchial asthma, usefulness of acupuncture have been proved through a controlled clinical trial which involved COPD patients who had not been able to control with standard care. Also, acupuncture was found to be useful in the management of bronchial asthma in a case series study in which acupuncture treatment was repeatedly applied with intervals without acupuncture. We have also demonstrated that acupuncture was useful for gastrointestinal disorders such as irritable bowel syndrome (IBS). Results of a case series with n-of-1 study design showed significant reduction in the symptoms during acupuncture treatment, while those in the period without acupuncture had been aggravated. Data from studies on diabetic complications such as peripheral neuropathy or gastropathy also showed usefulness of acupuncture. We considered that it is valuable to explore unknown usefulness of acupuncture in the field of internal medicine and prove effectiveness of acupuncture with appropriate scientific manner.

Background
Although there are several reports that electroacupuncture (EA) in the abdomen reduces fasting blood glucose and improves insulin sensitivity, the effects under a glucose load or hyperinsulinemic conditions have not yet been studied. In this study, we investigated the effect of EA at Zhongwan (CV12) under the conditions of an intravenous glucose tolerance test (IVGTT) and a hyperinsulinemic euglycemic clamp in normal Sprague-Dawlay (SD) rats.
Methods
Male SD rats were anesthetized with pentobarbital (40mg/kg i. p.) and then maintained by continuous infusion through a tail vein. Blood samples were drawn from the ventral tail artery during the fasting stage (baseline and 30min after), and at 2, 5, 10, 20, 30, 45, 60min after a glucose load (0.5g/kg). EA was performed for 30min (EA30, n=8) during the fasting stage and for 90min (EA90, n=8) during both the fasting and IVGTT periods. In the hyperinsulinemic euglycemic clamp experiments, insulin (2mU/kg/min) was infused through the tail vein, followed by infusion of 20% glucose at variable rates to maintain fasting blood glucose levels. EA was performed for 40min after a steady-state was achieved.
Results
Significant decreases in fasting blood glucose and increase in plasma insulin concentration were observed during the fasting period in rats in both the EA30 and EA90 groups, whereas rats in the control group (n=8) which did not receive any EA stimulation showed no such changes. Total glucose levels during the IVGTT were lower in the EA30 and EA90 groups compared to controls, with a significantly higher level of relative insulin secretion. During the hyperinsulinemic euglycemic clamp, glucose consumption was increased significantly by EA stimulation with a marked increase in both insulin concentration and sensitivity.
Conclusion
EA at CV12 accelerates glucose consumption during IVGTT and hyperinsulinemic conditions probably as a consequence of increased insulin sensitivity and/or increased plasma insulin concentration.

To investigate the effect of electro-acupuncture stimulation (EAS) on insulin sensitivity in rats, we performed several stimulations on Otsuka Long Evans Tokushima Fatty (OLETF) rats, during euglycemic clamp. We divided OLETF rats into five groups according to the kind of the stimulation: EAS at vagal innervated region of the auricle (AVA), EAS at non-vagal innervated region of the auricle (ANVA), EAS on the back of the body (AB), pinching on the back of the body (PB), and no stimulation on the body (NS). These procedures were also applied on Long Evans Tokushima Otsuka (LETO) rats as a control study.
Furthermore, we performed long-term stimulation (from six to 24 weeks of age) on OLETF rats to assess the preventive effect of those stimulations on the formation of the insulin resistance. EAS of pulse duration 300ms, 1.5V, 1Hz was applied for 10 or 15minutes. As a result, the glucose infusion rate (GIR) showed significantly higher levels during stimulation of PB group in LETO rats. On the other hand, the GIR of AVA group in LETO rats and PB group in OLETF rats were decreased by stimulation. The GIR in AVA group and AB group after long-term stimulation were significantly higher than those of NS group in OLETF rats. These results suggested that EAS at the auricle and the back is useful for the prevention of the formation of insulin resistance when it's applied before onset of the symptoms in OLETF rats.

Chronic obstructive pulmonary disease (COPD) causes severe respiratory dysfunction and severely limits patients' daily activities. We report a case of the patient with COPD whose respiratory symptoms were successfully improved by acupuncture. A 70-year-old man visited Meiji University of Oriental Medicine Hospital complaining of dyspnea during exercise on _??_. Despite strictly controlled medication and a regimen of home oxygen therapy (HOT), his general condition continued to worsen. Then a series of acupuncture treatment was started on _??_. The severity of dyspnea of the patient before acupuncture treatment was determined as level V according to Hugh-Jones classification, and spirometry showed severely disturbed respiratory functions (%VC: 63.5%, FEV₁%: 29.4%, PEFR: 84.8 1/min in the morning and 93.5 1/min at night). The basic combination of meridian points for the treatment of the case was LU1 (Zhongfu), CV12 (Zhongwan), CV4 (Guanyuan), LU5 (Chize), and BL13 (Feishu). The acupuncture needles were retained for ten minutes in each session. The single-subject research design (A-B-A method) was applied to detect the specific effect of the acupuncture treatment on the respiratory functions or the symptoms of the subject. “A” and “B” mean “treatment period” and “no treatment period” respectively. After 60 acupuncture treatments during a 14-month period, both the respiratory symptoms and the VAS for dyspnea showed improvement, which were specifically observed during the intervention period. Improvement was also reflected in the level of the Hugh-Jones classification and respiratory function test. It was suggested that acupuncture treatment might be effective for advanced cases of COPD.

[Objective] It is necessary to administer anti-cholinergic agents or glucagon during gastroscopy for inhibition of gastric peristalsis. However, application of these drugs are limited in patients with glaucoma, hypertension, benign prostate hyperplasia, heart disease, or diabetes mellitus because of possible adverse events.
Based on the report that acupuncture stimulation at CV 12 (Zhonguan, Chukan) inhibited gastric activity, we studied whether the acupuncture at CV 12 could be applicable as an alternative to these drugs.
[Method] Subjects in the present study were 60 patients who underwent gastroscopy at Meiji University of Oriental Medicine Hospital. They were allocated into two groups; acupuncture group (mean [SD] age, 66 [10]) and drug group (mean [SD] age, 64 [13])
Patients in the acupuncture group were given manual stimulation at CV 12 with an acupuncture needle for 10 minutes before examination and during gastroscopy.
After examination, a gastroscopist evaluated the magnitude of the peristalsis and disturbance during the examination using the visual analogue scale (VAS) and a 4-grade categorical scale.
Patients in the drug group were pre-administered anti-cholinergic drug or glucagon, and evaluated with the same scale.
[Results and Discussion] Inhibition score in the acupuncture group was lower but not statistically significant, as compared with the drug group, and the effect of acupuncture stimulation was acceptable to allow examination of the patients without severe disturbance.
Acupuncture may be a useful non-pharmacologic alternative to anti-cholinergic drugs and glucagon to inhibit gastric movement during gastroscopy, when these drugs could not be administered.

INTRODUCTION:Acupuncture has been reported to be useful for both physical and psychological symptoms. Here we report a case who complained of various physical symptoms due to advanced hepatocellular carcinoma effectively cared for with acupuncture.
Case:A 64-year-old female complained of general fatigue, constipation, and pain in the lower back and leg during her hospitalization for leg edema due to advanced hepatocellular carcinoma. Although the leg edema was improved by the administration of albumin, physical symptoms such as pain in the lower back and leg, constipation, or general fatigue remained.
We applied acupuncture with aiming at relaxing muscles (erector spinae, rectus femoris, right adductor) by a local needling approach, and to improve incomplete defecation by applying moxibustion at the acupoint on the abdomen.
METHOD:Faces Scale was used to evaluate general condition. Evaluation of the pain in the lower back and lower extremities were made with a Numerical Scale where 10 indicates the most painful, while 0 indicates no pain.
RESULT:Both general fatigue and pain in the lower extremities wererelieved after acupuncture treatments (FS for general condition improved from 3to 1, NS for pain decreased from 7 to 4). Also, the feeling of incomplete defecation disappeared.

[Background]Functional abdominal pain syndrome (FAPS) represents a chronic pain disorder localized in the abdomen and the symptoms largely are unrelated to food intake and defecation, which differ from other painful functional gastrointestinal disorders.
We report a case of FAPS whose symptom was successfully improved by acupuncture.
[Case Report]A 75-year-old female had been hospitalized at Meiji University of Integrative Medicine Hospital because of left lower abdominal pain from which she had repeatedly suffered for more than 2 years. Despite strict medication, her symptom had not been improved. After admission to the hospital, according to recommendation by her physician, acupuncture treatment was started. The patient received TCM-based acupuncture treatments five times a week over 13weeks. Primary acupuncture points used for the patient were LV3(Taichong), SP6 (Sanyinjiao), ST36 (Zusanli) and PC6 (Neiguan). Evaluation of the left lower abdominal pain was carried out with a Visual Analogue Scale (VAS). The Gastrointestinal Symptom Rating Scale (GSRS) was used to evaluate QOL related to the digestive symptoms. VAS for the left lower abdominal pain showed a remarkable decrease immediately after the initial acupuncture session. The symptom disappeared within 4 weeks after commencement of the treatment and never appeared during her hospitalization. GSRS was also improved and it was maintained during hospitalization.
[Conclusion]We suggested that acupuncture treatment might be one of the useful, non-pharmacological alternatives for symptoms of FAPS.

[Objective]Acupuncture has been described to be effective for acute vomiting induced by anti-cancer drugs of chemotherapy. However, the effect of acupuncture for the prolonged acute nausea that continues more than 24 hours from its onset after chemotherapy has not been satisfactorily investigated. In the present study, we report two cases of prolonged acute nausea induced by chemotherapy and effectively treated with acupuncture and moxibustion.
[Case 1] 79-year-old male who had diagnosed as early adenocarcinoma of the lung had chemotherapy by anticancer drug under hospitalization after right lower lung lobectomy. In spite of administration of anti-emetic agents, he complained of mild but persistent nausea that developed within 24 hours after chemotherapy and continued more than 24 hours from onset. Acupuncture at PC6 (Neiguwan) and ST25 (Tianshu) with moxibustion at CV12 (Zhongwan) and ST25 (Tianshu) were performed in addition to anti-emetics.
[Case 2] 64-year-old female who had undergone radiation therapy by gamma knife for metastatic brain tumors of adenocarcinoma of the lung had chemotherapy by anti-cancer drug under hospitalization. Since administration of anti-emetics during the first period of chemotherapy was less effective, moxibustion at ST25 and CV12 in addition to anti-emetics was performed during the second period of chemotherapy.
[Results]In both cases, the prolonged acute nausea was improved showing significant decrease in the VAS immediately after the treatment of acupuncture.
[Discussion]Severe nausea and vomiting might have been suppressed by anti-emetic agents, but mild acute nausea was prolonged and persisted. Prolonged acute nausea caused poor appetite and deterioration of Quality of Life (QOL) of patients in two cases.
Acupuncture with moxibustion and moxibustion could improve prolonged acute nausea and its related symptoms. These results of acupuncture with moxibustion and moxibustion suggest that acupuncture and moxibustion are useful treatment for prolonged acute nausea induced by chemotherapy and can be applied as complementary medicine to patients receiving anti-cancer chemotherapy.
