As many natural medicines absorb water at boiling, yields of the decoctions are affected by absorbed water. Therefore, we examined the quantity of imbibition of each crude drug at boiling. We used 75 kinds of crude drugs. After boiling 600ml of water, each natural medicine was boiled for 70 minutes. The medicine was left for 60 minutes, and then boiled again for 20 minutes. The quantity of imbibition of each natural medicine was measured at 10, 20, 30, 40, 60, 130, and 150 minutes. The maximum data among the quantity of imbibition at each point was labeled “maximum quantity of imbibition.” With regard to the maximum quantity of imbibition in natural medicines of plant origin, the range was from a maximum of 69.10g in Chrisanthemi Flos to a minimum of 3.26g in Persicae Semen. The average maximum quantity of imbibition was 22.51±13.00g, and there were large differences among each of the natural medicines. The quantity of imbibition at 10 minutes or 20 minutes was above 80% of each maximum quantity of imbibition on many crude drugs, but that gradually increased over the time course for some crude drugs.

Patients with an aortic root pseudoaneurysm communicating to the right atrium are rare. A 67-year-old woman underwent ascending aorta and total aortic arch replacement for acute type A aortic dissection at our institute 9 years prior to the current presentation. She was transported to our emergency department with complaints of chest pain, palpitations, and cold sensation. A continuous murmur was heard at the right sternal margin. Contrast-enhanced computed tomography (CT) and ultrasonic cardiography showed a huge pseudoaneurysm at the proximal anastomotic site and an aorto-right atrial fistula. Ascending aortic replacement with concomitant direct closure of the fistula was successfully performed. The patient was discharged in good condition on the 14th postoperative day. Careful follow-up with CT is important after acute type A aortic dissection repair.

The aim of the present study was to clarify whether ATP binding cassette transporters are refractory factors in head and neck cancer chemotherapy. For in vitro and in vivo chemotherapeutic studies, we employed a human salivary gland adenocarcinoma cell line (HSY) and a human oral squamous cell carcinoma cell line (SCCSK) with vincristine (VCR) at clinically equivalent doses. Western blot analysis, reverse transcription-polymerase chain reaction, in vivo evaluation in xenograft models inoculated with cultured carcinoma cell line and drug efflux analysis were performed. VCR-treated SCCSK and HSY cells, as well as xenografted SCCSK and HSY cells in tumor-bearing nude mice, were found to express MDR1/ABCB1 and MRP1/ ABCC1. In addition to MDR1 and MRP1 mRNA, HSY/VCR and its cloned cells expressed MRP7/ABCC10 mRNA, but SCCSK/VCR did not express MRP7. Furthermore, drug resistance to VCR and docetaxel decreased in HSY/VCR in the presence of a competitive MRP7 inhibitor, 17-beta-estradiol-(17-beta-D-glucuronide). These results indicate that MDR1 and MRP1 expression are refractory factors in head and neck cancer chemotherapy and suggest that induction of MRP7 expression is involved in drug resistance in salivary gland adenocarcinomas.

Purpose: To report a case of successful treatment using gabapentin against hot flashes due to LH-RH agonist in a patient with advanced prostate cancer. Case summary: A male patient in his seventies with advanced prostate cancer had hot flashes due to LH-RH agonist therapy. The patient began to notice hot flashes within a few months after starting hormone treatment. Oral gabapentin was administered at a starting dose of 400mg/day and was gradually escalated to 1,200mg/day. Within 7 days of administration, the patient achieved a partial improvement of his symptoms. After 17 days of gabapentin therapy, the hot flashes significantly improved. While the patient was taking a maintenance dose of 1,200mg/day, he remained to be asymptomatic. Conclusion: There are only a few reports (none in Japan) that show effectiveness of gabapentin against hot flashes due to hormone treatment in male patients with prostate cancer. Although the mechanism of the hot flash-relieving effect of gabapentin is not fully understood, this case report indicates that gabapentin may help treating patients suffering from intractable hot flashes.

We had previously reported a close association between pathological response and the maximum tumor standardized uptake value (SUVmax) measured by 18F-fluorodeoxyglucose positron emission tomography prior to chemotherapy in estrogen receptor (ER)-positive breast cancer. We hypothesized that glucose hypermetabolism by luminal B tumors may result in chemotherapy responsiveness. Using a single-gene expression assay, TargetPrint(R) (Agendia) and a 70-gene expression classifier, MammaPrint(R) (Agendia), we divided 20 patients with ER-positive primary breast cancer into luminal A and luminal B subtypes and compared the tumor SUVmax value between the two groups. A significantly higher SUVmax was measured for luminal B tumors (n=10; mean+/-SD, 7.6+/-5.6) than for luminal A tumors (n=10; mean+/-SD, 2.6+/-1.2; p=0.01). Glucose hypermetabolism could help predict intrinsic subtyping and chemotherapy responsiveness as a supplement to ER, progesterone receptor, HER2, and Ki-67 histochemical scores.

A rare case of an unruptured sinus of Valsalva aneurysm (SVA) in a 2-month-old male Maltese terrier weighing 1.0 kg with a heart murmur is presented. A right SVA and a ventricular septal defect (VSD) were diagnosed by echocardiography and cardiac catheterization. The dog died due to a worsening of his condition. The necropsy revealed the sinus of Valsalva to have a diameter of 7 mm and a VSD hole was on the opposite surface. This report is the first to describe an unruptured SVA in the right coronary cusp of a small dog.

BACKGROUND: Predictive factors for the efficacy of dipeptidyl peptidase-4 (DPP-4) inhibitors for lowering glycosylated hemoglobin (HbA1c) remain unclear in patients with type 2 diabetes mellitus. The aim of this study is therefore to clarify predictive factors of the efficacy of DPP-4 inhibitors for lowering HbA1c after 12 months of treatment. METHODS: A total of 191 consecutive type 2 diabetic patients (male sex 55%, mean age, 68.3+/-35.8 years), who had been treated with DPP-4 inhibitors for 12 months, were enrolled in this study and evaluated retrospectively. RESULTS: After 12 months of DPP-4 inhibitor treatment, random blood glucose level, and HbA1c level, decreased from 167+/-63 to 151+/-49 mg/dL (P<0.01), and from 7.5%+/-1.3% to 6.9%+/-0.9% (P<0.01) respectively, without severe side effects. Multiple regression analysis showed that predictors of DPP-4 inhibitor treatment efficacy in lowering HbA1c level after 12 months were a decrease in HbA1c level after 3 months of treatment, a high baseline HbA1c level, a low baseline body mass index, and the absence of coronary artery disease. CONCLUSION: Most suitable candidates for treatment with DPP-4 inhibitors are diabetics who are not obese and do not have coronary artery disease. In addition, long-term efficacy of DPP-4 inhibitors can be predicted by decrement of HbA1c after 3 months of treatment.

Objective:
The primary objective of this study was to evaluate the safety of niraparib 300 mg/day in Japanese patients with platinum-sensitive, relapsed ovarian cancer in a maintenance setting.
Methods:
Phase 2, multicenter, open-label, single-arm study enrolled Japanese patients with platinum-sensitive, relapsed ovarian cancer who had received ≥2 platinum-based regimens.The primary endpoint (incidence of grade 3 or 4 thrombocytopenia-related events within 30 days after initial niraparib administration) was justified by the incidences of a global pivotal phase 3 study and its post-hoc safety analysis on thrombocytopenia, the major hematological adverse event of niraparib. The overall safety analysis examined other treatment-emergent adverse events (TEAEs).
Results:
Enrolled patients (n=19) had a median (min, max) body weight of 53.9 (40.8–79.1) kg; all but one patient weighed <77 kg. Most (94.7%) patients initially received niraparib 300 mg/day but this decreased in subsequent cycles (mean±standard deviation dose intensity, 191.6±65.7 mg/day). In total, 6/19 (31.6%) patients experienced grade 3 or 4 thrombocytopenia-related events within 30 days of initial niraparib administration.Other common TEAEs included nausea, and decreased platelet or neutrophil counts. No progression-free or overall survival events occurred; only 1 of 4 response-evaluable patients had a post-baseline tumor assessment (stable disease).
Conclusion
The incidence of grade 3 or 4 thrombocytopenia-related events in Japanese ovarian cancer patients was similar to that in the corresponding non-Japanese study. Overall, the safety profile was acceptable and consistent with the known safety profile and previous experience with niraparib.

BACKGROUND:
Epidemiological evidence for the relationship between education and income and carotid intima-media thickness (CIMT) has been limited and inconsistent. The present cross-sectional study investigated this issue using baseline data from the Aidai Cohort Study.
METHODS:
Study subjects were 2012 Japanese men and women aged 34-88 years. Right and left CIMT were measured at the common carotid artery using an automated carotid ultrasonography device. Maximum CIMT was defined as the largest CIMT value in either the left or right common carotid artery. Carotid wall thickening was defined as a maximum CIMT value > 1.0 mm.
RESULTS:
The prevalence of carotid wall thickening was 13.0%. In participants under 60 years of age (n = 703) and in those aged 60 to 69 years (n = 837), neither education nor household income was associated with carotid wall thickening or with maximum CIMT. Among those aged 70 years or older (n = 472), however, higher educational level, but not household income, was independently related to a lower prevalence of carotid wall thickening: the multivariate-adjusted odds ratio for high vs. low educational level was 0.43 (95% confidence interval 0.21-0.83, p for trend = 0.01). A significant inverse association was observed between education, but not household income, and maximum CIMT (p for trend = 0.006).
CONCLUSIONS
Higher educational level may be associated with a lower prevalence of carotid wall thickening and a decrease in maximum CIMT only in participants aged 70 years or older.
