Notch signaling pathway plays an important role in regulating pancreatic endocrine and exocrine cell fate during pancreas development. Notch signaling is also expressed in adult pancreas. There are few studies on the effect of Notch on adult pancreas. Here, we investigated the role of Notch in islet mass and glucose homeostasis in adult pancreas using Notch1 antisense transgenic (NAS). Western blot analysis was performed for the liver of 8-week-old male NAS mice. We also conducted an intraperitoneal glucose tolerance test (IPGTT) and intraperitoneal insulin tolerance test in 8-week-old male NAS mice and male C57BL/6 mice (control). Morphologic observation of pancreatic islet and β-cell was conducted in two groups. Insulin secretion capacity in islets was measured by glucose-stimulated insulin secretion (GSIS) and perifusion. NAS mice showed higher glucose levels and lower insulin secretion in IPGTT than the control mice. There was no significant difference in insulin resistance. Total islet and β-cell masses were decreased in NAS mice. The number of large islets (≥250 µm) decreased while that of small islets (<250 µm) increased. Reduced insulin secretion was observed in GSIS and perifusion. Neurogenin3, neurogenic differentiation, and MAF bZIP transcription factor A levels increased in NAS mice. Our study provides that Notch1 inhibition decreased insulin secretion and decreased islet and β-cell masses. It is thought that Notch1 inhibition suppresses islet proliferation and induces differentiation of small islets. In conclusion, Notch signaling pathway may play an important role in β-cell mass determination and diabetes.

Bladder diverticulum can be caused by many varying factors. It is usually asymptomatic in nature and thus often found by chance. In adult males, it can develop as a result of increased intravesicular pressure in the presence of an underlying benign prostatic hyperplasia. We observed a case in which a patient with asymptomatic bladder diverticulum developed new urinary symptoms owing to an underlying neurogenic lower urinary tract disorder which occurred following a cerebral infarction.

Gastrointestinal graft-versus-host disease (GVHD) is a common complication after hematopoietic stem cell transplantation. Concomitant cytomegalovirus (CMV) enteritis worsens the prognosis of this condition. We report a case of small bowel perforation associated with gastrointestinal GVHD and CMV enteritis in a patient with leukemia who was successfully treated surgically. A 39-year-old man presented with intestinal perforation necessitating emergency surgical intervention. He was diagnosed with T-cell acute lymphoblastic leukemia and developed severe gastrointestinal GVHD and CMV enteritis after hematopoietic stem cell transplantation. His terminal ileum showed a perforation with diffuse wall thinning, and petechiae were observed over long segments of the distal ileum and the proximal colon. Small bowel segmental resection and a subtotal colectomy with a double-barreled ileocolostomy were performed. The patient recovered uneventfully after the operation. Based on reports described in the literature, surgery plays a minor role in the management of gastrointestinal GVHD; however, timely surgical intervention could be effective in selected patients.

Background/Aims:
Transarterial chemoembolization (TACE) is a standard treatment for intermediate-stage hepatocellular carcinoma (HCC), but there is much controversy about TACE refractoriness. The aim of this study was to identify trends in the actual clinical application of TACE and recognition of TACE refractoriness by Korean experts.
Methods:
In total, 17 questionnaires on TACE refractoriness were administered to 161 clinicians via an online survey. Multiple answers were allowed for some questions.
Results:
Most clinicians agreed that there is a need for standardization of TACE application through specific scoring systems (n=124, 77.0%). TACE refractoriness was predominantly expected by participants when recurrences were detected within 1 month (n=70, 43.5%), there were 4 to 6 tumors (n=77, 47.8%), the maximal tumor size was 3–5 cm (n=49, 30.4%), and when there was insufficient tumor necrosis despite TACE being repeated more than three times (n=78, 48.4%). Overall, sorafenib therapy (n=137) and radiotherapy (n=114) were preferred when repeated TACE was considered ineffective.
Conclusions
Treatment of HCC is often based on the clinical judgment of clinicians because of the heterogeneity among individuals. Experts need to continue discussions on the standardization and sub-classification of HCC treatment guidelines in Korea.

Musculoskeletal problems in the upper extremity after stroke are common conditions affecting the shoulder, elbow, wrist and hand, which are often symptomatic. These symptomatic conditions include complex regional pain syndrome type 1, secondary adhesive capsulitis of the shoulder, spasticity, secondary mechanical injuries, which often presents simultaneously in combined nature, so that one targeted treatment is not always successful. Musculoskeletal pain and complication is one of the reasons, for patients not being possible to start or participate in the daily regular rehabilitation programs actively after stroke.

BACKGROUND: The aim of this study was to assess the psychological well-being and treatment satisfaction in patients with type 2 diabetes mellitus in a general hospital in Korea. METHODS: This study included 440 type 2 diabetes patients above 20 years of age. Well-Being Questionnaire-12 (WBQ-12) and Diabetes Treatment Satisfaction Questionnaire were used to survey well-being and treatment satisfaction, respectively. WBQ-12 consists of 4 categories: negative well-being (NWB), energy (ENE), positive well-being (PWB), and general well-being (GWB). RESULTS: There were significant associations between NWB scores and women, low education, low-income, and number of hospital admissions. Significant associations were also identified between ENE scores and men, higher education, insulin nonusers, high-income, compliance with recommended exercise, number of medications, satisfaction with treatment time, and poor glycemic control. PWB scores were significantly associated with high-income, satisfaction with waiting and treatment times, compliance with recommended diet and exercise, and number of medications. GWB scores were significantly associated with men, higher education, high-income, satisfaction with waiting and treatment times, compliance with recommended exercise, and number of medications. Treatment satisfaction was significantly associated with age, satisfaction with waiting and treatment times, compliance with recommended diet and exercise, and duration of diabetes. CONCLUSION: Diabetes care requires psychosocial support in addition to medical care. Unlike Western studies, our study found that satisfaction with waiting and treatment times had a strong correlation with well-being and treatment satisfaction in diabetes patients.

OBJECTIVE: To evaluate the effects of epidural electrical stimulation (EES) and repetitive transcranial magnetic stimulation (rTMS) on motor recovery and brain activity in a rat model of diffuse traumatic brain injury (TBI) compared to the control group. METHODS: Thirty rats weighing 270-285 g with diffuse TBI with 45 kg/cm2 using a weight-drop model were assigned to one of three groups: the EES group (ES) (anodal electrical stimulation at 50 Hz), the rTMS group (MS) (magnetic stimulation at 10 Hz, 3-second stimulation with 6-second intervals, 4,000 total stimulations per day), and the sham-treated control group (sham) (no stimulation). They were pre-trained to perform a single-pellet reaching task (SPRT) and a rotarod test (RRT) for 14 days. Diffuse TBI was then induced and an electrode was implanted over the dominant motor cortex. The changes in SPRT success rate, RRT performance time rate and the expression of c-Fos after two weeks of EES or rTMS were tracked. RESULTS: SPRT improved significantly from day 8 to day 12 in the ES group and from day 4 to day 14 in the MS group (p<0.05) compared to the sham group. RRT improved significantly from day 6 to day 11 in ES and from day 4 to day 9 in MS compared to the sham group. The ES and MS groups showed increased expression of c-Fos in the cerebral cortex compared to the sham group. CONCLUSION: ES or MS in a rat model of diffuse TBI can be used to enhance motor recovery and brain activity.
