| 抄録 | We analyzed the treatment effects of chidamide and decitabine in combination with a HAG (homoharringtonine, cytarabine, G-CSF) priming regimen (CDHAG) in acute myeloid leukemia (AML) patients with TP53 mutation. Seven TP53 mutated AML patients were treated with CDHAG. The treatment effects were assessed using hemogram detection and bone marrow aspirate. The possible side effects were evaluated based on both hematological and non-hematological toxicity. Four of the seven patients were classified as having achieved complete remission after CDHAG treatment; one patient was considered to have achieved partial remission, and the remaining two patients were considered in non-remission. The overall response rate (ORR) to CDHAG was 71.4%. Regarding the side effects, the hematological toxicity level of the seven patients ranged from level III to level IV, and infections that occurred at lung, blood, and skin were recorded. Nausea, vomiting, liver injury, and kidney injury were also detected. However, all side effects were attenuated by proper management. The CDHAG regimen clearly improved the ORR (71.4%) of TP53-mutated AML patients, with no severe side effects. |

| 抄録 | Targeted therapies for malignant melanoma have improved patients’ prognoses. A primary gastrointestinal malignant melanoma is very rare, with no standard treatment strategy. We treated a 78-year-old Japanese female with advanced primary gastrointestinal melanoma of the descending colon and gallbladder. We administered a multidisciplinary treatment: surgical resection of the descending colon and gallbladder tumors, resection of the metastatic lymph nodes behind the pancreas head, and immune checkpoint antibody-blockade therapy (nivolumab) for ~4 years. PET/CT demonstrated no recurrent lesion for > 3 years. Multidisciplinary therapies (e.g., surgery, chemotherapy, radiotherapy, target therapy, and immune checkpoint antibody-blockade therapy) can successfully treat primary gastrointestinal malignant melanoma. |

| 抄録 | To clarify the relevance of prolactin (PRL) to clinical parameters in patients who visited our general medicine department, medical records of 353 patients in whom serum PRL levels were measured during the period from 2016 to 2018 were retrospectively reviewed. Data for 140 patients (M/F: 42/98) were analyzed after excluding patients lacking detailed records and patients taking dopaminergic agents. Median serum PRL levels were significantly lower in males than females: 6.5 ng/ml (IQR: 4.2-10.3) versus 8.1 ng/ml (5.9-12.9), respectively. Pain and general fatigue were the major symptoms at the first visit, and past histories of hypertension and dyslipidemia were frequent. Male patients with relatively high PRL levels (≥ 10 ng/ml) had significantly lower levels of serum albumin and significantly higher levels of serum LDH than those with low PRL (< 10 ng/ml). There were significant correlations of male PRL level with the erythrocyte sedimentation rate (R=0.62), serum LDH level (R=0.39) and serum albumin level (R=−0.52), while the level of serum CRP (R=0.33) showed an insignificant but weak positive correlation with PRL level. Collectively, these results show that PRL levels had gender-specific relevance to various clinical factors, with PRL levels in males being significantly related to inflammatory status. |

| 抄録 | A 65-year-old Japanese woman developed vesicular eruptions on her right ear due to varicella zoster virus (VZV) reactivation, followed by cranial polyneuritis and meningitis affecting her right cranial nerves V, VII, VIII, IX, and X. After acyclovir administration, her facial paralysis worsened. Intravenous methylprednisolone and vitamin C were administered on Day 4 post-admission. Her symptoms steadily improved, and by Day 45 she had fully recovered. Cranial polyneuritis is a rare complication of VZV reactivation, and there is no established method of treatment. This is the first report of full recovery from cranial polyneuritis using intravenous vitamin C as ancillary treatment. |

| 抄録 | Heart diseases are one of the major causes of morbidity and mortality worldwide. Despite major advances in drug and interventional therapies, surgical procedures, and organ transplantation, further research into new therapeutic options is still necessary. Stem cell therapy has emerged as one option for the treatment of a variety of heart diseases. Although a large number of clinical trials have shown stem cell therapy to be a promising therapeutic approach, the results obtained from these clinical studies are inconsistent, and stem cell-based improvements of heart performance and cardiac remodeling were found to be quite limited. Since the precise mechanisms underlying the therapeutic actions of stem cells are still under debate, researchers have developed a variety of strategies to improve and boost the potency of stem cells in repair. In this review, we summarize both the current therapeutic strategies using stem cells and future directions for enhancing stem cell potency. |

| 抄録 | We performed a retrospective cohort study of 911 high-energy trauma patients who underwent chest CT scans at least twice after admission. We hypothesized that in high-energy trauma patients, a high-inspired oxygen concentration delivered after admission results in dorsal atelectasis. The study’s primary outcome was dorsal atelectasis formation diagnosed based on CT images. We defined dorsal atelectasis as the presence of atelectasis at ≥ 10 mm thick on CT images. We defined high-inspired oxygen concentration as >60% oxygen delivered between two CT scans. Four hundred sixty-five patients (51.0%) developed atelectasis according to the second CT scan, and 338 (37.1%) received a high-inspired oxygen concentration. A univariate analysis showed that the rate of the high-inspired oxygen concentration in the atelectasis group was significantly higher than that in the non-atelectasis group (43.4% vs. 30.1%, p<0.001). However, a logistic regression analysis showed that there was no significant relationship between the oxygen concentration and the formation of dorsal atelectasis (OR: 1.197, 95%CI: 0.852-1.683, p=0.30). Age, the Injury Severity Score, BMI, and smoking were found to be risk factors of dorsal atelectasis formation in high-energy trauma patients. There was no relationship between the oxygen concentration and atelectasis formation in our series of high-energy trauma patients. |

| 抄録 | An association between preeclampsia and (pro)renin was recently reported. Intracellular signaling of the (pro) renin receptor [(P)RR] increases the expressions of TGF-β and PAI-1. In this study we sought to clarify the involvement of (pro)renin in the pathogenesis of preeclampsia via the intracellular signaling of (P)RR on preeclampsia placentas. Activated (pro)renin plasma concentrations were compared between pregnant women with (n=15) and without (n=28) preeclampsia. The placentas were immunohistochemically evaluated with anti-HIF-1α and anti-(P)RR antibodies. HTR-8/SVneo cells were cultured under hypoxic conditions and treated with human recombinant (pro)renin. The mRNA expressions of HIF-1α, (P)RR, PAI-1, TGF-β, and ET-1 were also examined by real-time RCR. The activated (pro)renin plasma concentration was significantly higher in the third vs. the second trimester in the preeclampsia patients. HIF-1α and (P)RR expressions were significantly increased in the preeclampsia placentas. The mRNA expressions of PAI-1, TGF-β, and ET-1 were significantly increased in the experiments using recombinant (pro)renin vs. hypoxic conditions. (P)RR expression in preeclampsia placentas is increased by persistent hypoxia through the second and third trimesters, and PAI-1, TGF-β, and ET-1 production is increased via (P)RR. Our results suggest that ET-1 production via the intracellular signaling of (P)RR is important in the pathogenesis of preeclampsia. |

| 抄録 | Laparoscopic radical cystectomy (LRC) is a standard surgical treatment for muscle-invasive bladder cancer and high-risk non-muscle-invasive bladder cancer. LRC is a less invasive modality than conventional open surgery. Therefore, even elderly patients with invasive bladder cancer may be candidates for LRC. In this study, a comparative analysis of perioperative/oncological outcomes between elderly patients and younger patients who underwent LRC was performed to assess the feasibility of LRC in elderly patients. Sixty-eight consecutive patients who underwent LRC between October 2013 and March 2018 were enrolled and stratified into those younger than 75 years (n=37) and those ≥ 75 years old (n=31). The median follow-up period was 28.2 months. The preoperative and operative parameters and complications were similar in both groups. The 2-year overall survival (OS) was 64.4% in the younger vs. 76.4% in the elderly group (p=0.053), cancer-specific survival (CSS) was 79.3% vs. 81.7% (p=0.187), and recurrence-free survival (RFS) was 58.2% vs. 75.7% (p=0.174), respectively. No significant differences were observed in OS, CSS, or RFS between the groups. No significant differences were found between the groups with respect to peri-surgical/oncological outcomes. We conclude that LRC is feasible in elderly patients. |

| 抄録 | Gliomas are characterized as highly diffuse infiltrating tumors, and currently available treatments such as surgery, radiation and chemotherapy are unfeasible or show limited efficacy against these tumors. Recent genetic and epigenetic analyses of glioma have revealed increasing evidence of the role of driver genetic alterations in glioma development and led to the identification of prognostic factors. Despite these findings, the survival rates of glioma patients remain low, and alternative treatments and novel targets are needed. Recent studies identified neural stem cells as the possible origin of gliomas, and some evidence has revealed shared functions and mechanisms between glioma cells and neurons, also supporting their similarity. The cytoskeleton plays important roles in the migration of normal cells as well as cancer cells. Recent reports have described a role for microtubules, a component of the cytoskeleton, in glioma invasion. Notably, several factors that regulate microtubule functions, such as microtubule-associated proteins, plus-end tracking proteins, or motor proteins, are upregulated in glioma tissues compared with normal tissue, and upregulation of these factors is associated with high invasiveness of glioma cells. In this review, we describe the mechanism of microtubules in glioma invasion and discuss the possibility of microtubule-targeted therapy to inhibit glioma invasion. |

| 抄録 | The basement membrane (BM) is composed of various extracellular molecules and regulates tissue regeneration and maintenance. Here, we demonstrate that collagen XVIII was spatiotemporally expressed in the BM during skin wound healing in a mouse excisional wound-splinting model. Re-epithelialization was detected at days 3 and 6 post-wounding. The ultrastructure of epidermal BM was discontinuous at day 3, whereas on day 6 a continuous BM was observed in the region proximal to the wound edge. Immunohistochemistry demonstrated that collagen XVIII was deposited in the BM zone beneath newly forming epidermis in day 3 and 6 wounds. Laminin-332, known to be the earliest BM component appearing in wounds, was colocalized with collagen XVIII in the epidermal BM zone at days 3 and 6. The deposition of α1(IV) collagen and nidogen-1 in the epidermal BM zone occurred later than that of collagen XVIII. We also observed the short isoform of collagen XVIII in the epidermal BM zone at day 3 post-wounding. Collectively, our results suggested that collagen XVIII plays a role in the formation of the dermal-epidermal junction during re-epithelialization, and that it is the short isoform that is involved in the early phase of re-epithelialization. |

| 抄録 | Post-orthotopic liver transplantation (OLT) hepatitis B recurrence is well-controlled with a nucleos(t)ide analogue and hepatitis B immunoglobulin (HBIG) combination, but the high cost and the potential risk of unknown infection associated with HBIG remain unresolved issues. Low-cost recombinant hepatitis B virus (HBV) vaccine administration is a potential solution to these problems. We retrospectively analyzed the rate and predictive factors of HBV vaccine success in 49 post-OLT patients: liver cirrhosis-type B (LC-B), n=28 patients; acute liver failure-type B (ALF-B), n=8; and non-HBV-related end-stage liver disease (non-B ESLD) who received a liver from anti-hepatitis B core antibody-positive donors, n=13. A positive anti-hepatitis B surface antibody response was achieved in 29% (8/28) of the LC-B group, 88% (7/8) of the ALF-B group, and 44% (4/9) of the adult non-B ESLD group. All four non-B ESLD infants showed vaccine success. The predictive factors for a good response in LC-B were young age, marital donor, and high donor age. ALF-B and non-B ESLD infants are thus good vaccination candidates. LC-B patients with marital donors are also good candidates, perhaps because the donated liver maintains an efficient immune memory to HBV, as the donors had already been infected in adulthood and showed adequate anti-HBV immune responses. |

| 抄録 | Background: Hemodialysis-related heart failure has been considered to be associated with excessive blood flow through the arteriovenous (AV) shunt used for vascular access. However, some patients undergoing dialysis have heart failure in the absence of an increase in cardiac output (CO) related to shunt blood-flow loading because the loading cannot be compensated for by increasing CO. This condition may be challenging to manage ; thus, early diagnosis is important. Methods and Results: Twelve patients (mean age, 71 years ; 9 men) with end-stage renal disease, dialysis-related heart failure, a high brain natriuretic peptide (BNP) level, and a mean New York Heart Association (NYHA) class of II underwent AV shunt closure. Their cardiac index (CI), pre- and post-dialysis BNP levels, and several cardiac variables were assessed pre- and postoperatively. All patients achieved relief of heart failure symptoms and a reduction in NYHA class after AV closure, but six patients had a postoperative increase in CI (the "non-high-output" cardiac failure group), whereas the other six had a decrease in CI (the "high-output" cardiac failure group). The high-output patients had greater improvements in BNP levels and most cardiac variables compared to the non-high-output group ; therefore, the heart failure in the non-high-output patients was considered more serious than that in the high-output group. Conclusions: The selection of effective strategies for treating dialysis-related heart failure may depend partly on identifying which patients have non-high-output failure. Such identification requires serial measurements of BNP levels and evaluations of cardiac variables other than the ejection fraction. |

| 抄録 | There is increasing interest in the intrinsic activity of the resting brain, especially the activity slower than 0.1Hz (i.e., low-frequency oscillations, or LFOs). To investigate the origin of LFOs observed in functional near-infrared spectroscopy (fNIRS), we recorded multichannel fNIRS and electroencephalography (EEG) from the frontal cortex of 11 healthy young volunteers in the resting state. Electrocardiography (ECG), electro-oculography and respiration were also measured. Synchronous oscillations of oxy-hemoglobin (oxy-Hb) around 1.0Hz were detected in all fNIRS channels, and their frequency was consistent with a peak frequency of ECG, suggesting the changes of cerebral blood flow due to heart beats. In addition, oxy-Hb oscillations around 0.1Hz (i.e., LFOs) appeared in the fNIRS. The channels where LFOs appeared differed among the subjects, and the LFOs appeared or disappeared even in the same fNIRS channels. The appearance of LFOs in fNIRS channels was significantly higher when the LFOs appeared on the EEG in the adjacent EEG electrodes compared to when LFOs did not appear on EEG. The amplitude and coherence (synchronicity) of the LFOs were increased by changing the subjects' position from dorsal to the sitting position in both fNIRS and EEG, and the coherence in particular was increased in the homologous fNIRS channels on the bilateral hemispheres. These results suggest that LFOs of oxy-Hb couple with resting-state EEG activity. |
