		                        			While several previous studies have indicated the link between periodontal disease (PD) and myocardial infarction (MI), the underlying mechanisms remain unclear. Autophagy, a cellular quality control process that is activated in several diseases, including heart failure, can be suppressed by Porphyromonas gingivalis (P.g.). However, it is uncertain whether autophagy impairment by periodontal pathogens stimulates the development of cardiac dysfunction after MI. Thus, this study aimed to investigate the relationship between PD and the development of MI while focusing on the role of autophagy. Neonatal rat cardiomyocytes (NRCMs) and MI model mice were inoculated with wild-type P.g. or gingipain-deficient P.g. to assess the effect of autophagy inhibition by P.g. Wild-type P.g.-inoculated NRCMs had lower cell viability than those inoculated with gingipain-deficient P.g. This study also revealed that gingipains can cleave vesicle-associated membrane protein 8 (VAMP8), a protein involved in lysosomal sensitive factor attachment protein receptors (SNAREs), at the 47th lysine residue, thereby inhibiting autophagy. Wild-type P.g.-inoculated MI model mice were more susceptible to cardiac rupture, with lower survival rates and autophagy activity than gingipain-deficient P.g.-inoculated MI model mice. After inoculating genetically modified MI model mice (VAMP8-K47A) with wild-type P.g., they exhibited significantly increased autophagy activation compared with the MI model mice inoculated with wild-type P.g., which suppressed cardiac rupture and enhanced overall survival rates. These findings suggest that gingipains, which are virulence factors of P.g., impair the infarcted myocardium by cleaving VAMP8 and disrupting autophagy. This study confirms the strong association between PD and MI and provides new insights into the potential role of autophagy in this relationship.

Idiopathic mesenteric phlebosclerosis (IMP) is a rare chronic ischemic intestinal disease, mainly in the right hemicolon, characterized by dark purple mucosa on colonoscopy and calcifications of the intestinal wall and mesenteric veins on abdominal radiography and computed tomography. In recent years, many patients who developed IMP over the long-term administration of Kampo medicines have been reported. However, the present status of IMP in patients under long-term treatment with Kampo medicines in departments specializing in Kampo therapy is unclear. We surveyed whether there were any IMP outpatients followed for 5 years or more at the Department of Oriental Traditional Medical Center, Suwa Central Hospital. We detected 2 of 257 (0.8%) patients having IMP. Both patients had undergone long-term treatment with Gardenia fruit. One of them underwent surgery due to acute abdomen, but the other was asymptomatic. The etiology and pathogenesis of IMP are still unclear. However, in patients undergoing long-term treatment with Kampo medicines, particularly containing Gardenia fruit, the possible presence of IMP should be taken into consideration, and active screening using imaging examinations is necessary even in asymptomatic patients.

		                        			Japanese version of the Constitution in Chinese Medicine Questionnaire (CCMQ-J) in Chinese consists of 60 items for 9 sub-scales called Gentleness, Qi-deficiency, Yang-deficiency, Yin-deficiency, Phlegm-wetness, Wet-heat, Blood-stasis, Qi-depression, and Special diathesis. Each question is answered by choosing one form 5 grades of a Likert scale where the grades from 1 to 5 corresponding to Never, Rarely, Sometimes, Often and Always, respectively. In the present study, we examined the relationship of scores based on 597 respondents to 60 items. We tentatively classified 60 items into 12 groups by utilizing the Ward’s hierarchical clustering method and discussed similarity of items and 9 body conditions. Body Mass Index (BMI) and age can be explained by the score of 60 items by partial least square model. Significantly high correlation coefficients between real and estimated values were obtained for BMI (0.81 for male and 0.82 for female) and age (0.82 for male and 0.83 for female). Those results indicate that the answers to the 60 items can reflect aging and BMI properties and CCMQ-J can be used to assess the situation of health for evaluating the actual aging conditions in human.

		                        			There have been few reports on an antiemetic effect of bakumondoto. An 84 year old man was referred to the department of internal medicine for Kampo treatment of intractable vomiting since having a gastrectomy 6 years previously. He had experienced persistent regurgitation of gastric fluids at dawn and antiemetic and antiacid drugs were of little help. He had had a gastrojejunostomy 4 years previously for an intestinal obstruction. After the gastrojejunostomy, vomiting persisted despite of the administration of antiacids, rikkunshito or daikenchuto. Physical examination revealed only slight edema of the legs. An upper gastrointestinal series, blood tests and head CT scan revealed no specific vomiting cause. After referral to our department, we tried hangeshashinto, and shinbuto in vain. Then we prescribed bakumondoto. He reported that the frequency of his vomiting reduced in 3 weeks, and that the vomiting disappeared in 2 more weeks. Thus we consider that not only cough but also vomiting can be treated with bakumondoto.

		                        			This study evaluated the exercise profile (heart rate, cycling speed and pedal cadence) during 25-30 km cycling and fitness and health level for adults (11 males: 69.6 ± 4.7 yrs; 6 females: 66.3 ± 4.9 yrs) with a recreational cycling habit (27.6 ± 14.8 km/week). Exercise intensity at a constant speed on a flat road during male and female cycling was 71.2 ± 11.5 and 66.8 ± 11.4% heart rate reserved (HRR), respectively. Exercise intensity over 60% HRR occupied 72% of cycling time. Peak intensity during male and female cycling was 89.2 ± 8.9 and 93.1 ± 6.1% HRR, respectively. VO2max and CS (chair stand)-30 test for male and female were 40.3 ± 4.3 and 37.7 ± 2.4 ml/kg/min, and 30.8 ± 3.1 and 30.1 ± 3.2 times, respectively. The muscle cross-sectional area of thigh extensor and flexor measured by MRI were 55.4 ± 6.5 and 58.3 ± 13.3 cm2 for male, and 45.5 ± 6.4 and 50.2 ± 5.7 cm2 for female, respectively. Blood profile for HDL-C (cholesterol), LDL-C and HbA1c (JDS) for male and female were 65.9 ± 8.2 and 67.9 ± 10.6 mg/dl, 112.3 ± 32.0 and 130.6 ± 12.3 mg/dl, and 4.8 ± 0.4 and 4.7 ± 0.1%, respectively. Fitness level and blood profile results were superior to those of the same aged adults. We concluded that the exercise intensity of cycling by middle and older adults with a recreational cycling habit is high and their fitness and health level are higher than average adults.

		                        			Crohn disease (CD) is a chronic inflammatory bowel disease that affects the entire gastrointestinal tract but is most frequently localized to the large and small bowel. Small bowel endoscopy helps with the differential diagnosis of CD in suspected CD patients. Early diagnosis of CD is preferable for suspected CD conditions to improve chronic inflammatory infiltrates, fibrosis. Small bowel endoscopy can help with the early detection of active disease, thus leading to early therapy before the onset of clinical symptoms of established CD. Some patients with CD have mucosal inflammatory changes not in the terminal ileum but in the proximal small bowel. Conventional ileocolonoscopy cannot detect ileal involvement proximal to the terminal ileum. Small bowel endoscopy, however, can be useful for evaluating these small bowel involvements in patients with CD. Small bowel endoscopy by endoscopic balloon dilation (EBD) enables the treatment of small bowel strictures in patients with CD. However, many practical issues still need to be addressed, such as endoscopic findings for early detection of CD, application compared with other imaging modalities, determination of the appropriate interval for endoscopic surveillance of small bowel lesions in patients with CD, and long-term prognosis after EBD.

		                        			Chinese herbal medicine has historically been used for the treatment of renal disease. There are some medi cines such as rhubarb and Ompito that delay the need for dialysis. However, they only attenuate the 1/Cr-time slope but cannot reduce the Cr level. In this study, four chronic renal failure (CRF) patients who had not responded to any Western medicine were treated effectively with Astragali Radix, a traditional herbal medi cine. Serum creatinine (Cr) was clearly improved, and necessity for dialysis was delayed. In two patients, Cr was controlled stably over four years. There were no adverse effects, and no noteworthy changes in the lev els of serum phosphorus, potassium and uric acid between before and after treatment were observed. This study suggests that Astragali Radix is a useful agent in the treatment of CRF.

The 3 patients experienced 2 com mon features, including an obstructive and a cold feeling in the pit of the stomach. Moreover, a cessation or significant decrease in cough and sputum was observed following ninjinto administration. Ninjinto is usually used to treat digestive disorders. However, these findings suggest that ninjinto may also be used for the treat ment of respiratory disorders.

We used a numerical rating scale (NRS) to classify each ESC sensation over the five days in this July-November period.To confirm physical symptoms, we used Terasawa's diagnostic scores for ki, ketsu, and sui. We defined ESC as mean NRSgeq ≥ 5.RESULTS : We documented 17 participants with ESC in November. The multivariate adjusted odds ratio for ESC was11.6 (95% CI 1.9 to 97.5) for the physical characteristic “edema”. Participants with ESC were shorter in stature than participants without ESC (-5.9cm ; 95% CI -8.6 to -3.1).CONCLUSION : Participants with edema and short stature have a high risk for ESC.

		                        			Pouchitis is the most common complication following ileal pouch-anal anastomosis in patients with ulcerative colitis and is strongly correlated with the risk of pouch failure and malignant mucosal transformation in the pouch. Here we report a case treated successfully with the Kampo decoction, daitokato. A 41-year-old male treated with ileal pouch-anal anastomosis due to severe ulcerative colitis suffered from repeated pouchitis and stenosis of the ileal pouch post-operatively. He complained of general fatigue, chills, continuous lower abdominal pain and discomfort, and severe pain with evacuation. Initial treatment with antibiotics and painkillers was ineffective, so the patient came to our hospital's Kampo clinic, where he was initially prescribed the decoction, shokenchuto. This proved ineffective at resolving his fatigue. Subsequent treatment with ogikenchuto improved physical strength but was ineffective for pouchitis. Antibiotic resistant pouchitis occurred afterwards and we attempted treatment with saikokeishito decoction and the extracts, hochuekkito and juzentaihoto, which similarly improved fatigue but not pouchitis. Following administration of daitokato, instances of pouchitis were reduced with no recurrence 6 months post-treatment. This case illustrates the therapeutic efficacy of daitokato in improving ileal pouch disorders resistant to treatment with Western medicine.
