Granzyme A (GzmA) was first identified as a cytotoxic T lymphocyte protease protein with limited tissue expression. A number of cellular proteins are known to be cleaved by GzmA, and its function is to induce apoptosis. Histones H1, H2B, and H3 were identified as GzmA substrates during apoptotic cell death. Here, we demonstrated that histone H4 was cleaved by GzmA during staurosporine-induced cell death; however, in the presence of caspase inhibitors, staurosporine-treated Raji cells underwent necroptosis instead of apoptosis. Furthermore, histone H4 cleavage was blocked by the GzmA inhibitor nafamostat mesylate and by GzmA knockdown using siRNA. These results suggest that histone H4 is a novel substrate for GzmA in staurosporine-induced cells.

Disease associated with microorganisms are far from resolved by current therapeutics. One of effective approach to health maintenance and disease control is the use of dietary bacterial and carbohydrate supplements. This comprises use of probiotics and prebiotics. Probiotics mean the live microorganisms, which when administered in adequate amounts confer a health benefit on the host. Prebiotics mean a nondigestible food ingredient that beneficially affects the host by selectively stimulating the growth and/or activity of one or a limited number of bacteria that can Improve the host health. Especially, probiotics has the relation which is close with innate immunity and adaptive immunity. And probiotics has the clinical value with many disease like lactose intolerance, constipation, acute gastroenteritis, food hypersensitivity and allergy, atopic dermatitis, crohn's disease, rheumatoid arthritis, pelvic radiotherapy, intestinal inflammation and chemical exposure, colon cancer, inhibitory effect of Helicobacter pylori and lowering the level of cholesterol. We use jointly korean medicine and probiotics and it has the more therapeutic effect in the many disease.

We report a rare case of Meckel's diverticulum in a boy who initially presented with chronic iron deficiency anemia (IDA) without any history of gastrointestinal (GI) bleeding at 8 years-old. Isolated small bowel Crohn's disease was suspected based on findings of small bowel ulcers on capsule endoscopy. At four years from initial presentation, he developed massive GI bleeding. Abdominal computed tomographic angiography and small bowel series revealed findings suggestive of Meckel's diverticulum. Meckel's diverticulum should be suspected in children with unexplained chronic IDA even in the absence of prominent GI bleeding and negative findings on repetitive Meckel's scans. Moreover, Meckel's diverticulum should be included in the differential diagnosis of isolated small bowel Crohn's disease when the disease is limited to a short segment of the distal small bowel, as ulcers and inflammation may result as a consequence of acid secreted from adjacent heterotopic gastric mucosa constituting the Meckel's diverticulum.

Background: Evaluation of the effectiveness of caudal epidural injection on pain, spine mobility, disease activity, and activity of daily living in axial spondyloarthritis (SpA) patients. Methods: A total sample of 47 patients were registered in this study. They were randomly assigned into 2 groups; Group I received caudal epidural injections, ultrasound-guided, with 1% lidocaine hydrochloride mixed with triamcinolone, whereas Group II did not receive any injections. All participants fulfilled the ASAS criteria for axial SpA. Outcome measures were as follows: visual analogue scale, Oswestry disability index (ODI), modified Schober test, lateral lumbar flexion, and Ankylosing Spondylitis Disease Activity Score (ASDAS) with assessment at baseline, 2 weeks, and 8 weeks post-treatment. This clinical trial was registered on clinicaltrials.gov under the number NCT04143165. Results: There was a significant difference between both groups regarding pain, ODI, spine mobility and ASDAS scores in favor of group I. This effect was at its maximum after 2 weeks. Despite the decline of this effect after 2 months, the difference between the groups remained significant. Higher disease activity, younger age, and shorter disease duration were associated with better outcomes. Conclusions: Epidural injection of lidocaine and triamcinolone is a cost effective and a practical technique for controlling pain, as well as improving the function of the spine and disease activity scores in axial SpA patients with acceptable complications and relatively sustained effect.

Glutaric aciduria type 1 (GA1; OMIM #231670) is a rare autosomal recessive inherited neurometabolic disorder caused by the deficiency of glutaryl-CoA dehydrogenase. Infantile-onset GA1 is the most common form characterized by striatal injury and progressive movement disorder, and it is often triggered by an acute encephalopathic crisis within the first three years of life. Once this crisis occurs, there is a high likelihood for ineffective or limited conventional interventions, neurological disorders, or even death. Therefore, early diagnosis and immediate preventive management, such as dietary therapy, is essential. In the past decades, newborn screening (NBS) by tandem mass spectrometry for GA1 has been largely introduced in many countries including Korea, and it has led to improvements in the neurological outcomes of patients with GA1. In this review, the clinical symptoms, natural histories, and outcomes before and after the introduction of NBS in patients are discussed.

The use of pediatric cardiothoracic CT for congenital heart disease (CHD) was traditionally limited to the morphologic evaluation of the extracardiac thoracic vessels, lungs, and airways. Currently, the applications of CT have increased, owing to technological advancements in hardware and software as well as several dose-reduction measures. In the previously published part 1 of the guideline by the Asian Society of Cardiovascular Imaging Congenital Heart Disease Study Group, we reviewed the prerequisite technical knowledge for clinical applications in a user-friendly and vendor-specific manner. Herein, we present the second part of our guideline on contemporary clinical applications of pediatric cardiothoracic CT for CHD based on the consensus of experts from the Asian Society of Cardiovascular Imaging CHD Study Group. This guideline describes up-to-date clinical applications effectively in a systematic fashion.

The periodontal diseases are infections caused by bacteria in oral biofilm, a gelatinous mat commonly called dental plaque, which is a complex microbial community that forms and adhere to tooth surfaces. Host immune-pathogen interaction in periodontal disease appears to be a complex process, which is regulated not only by the acquired immunity to deal with ever-growing and -invading microorganisms in periodontal pockets, but also by genetic and/or environmental factors. However, our understanding of the pathogenesis in human periodontal diseases is limited by the lack of specific and sensitive tools or models to study the complex microbial challenges and their interactions with the host's immune system. Recent advances in cellular and molecular biology research have demonstrated the importance of the acquired immune system in fighting the virulent periodontal pathogens and in protecting the host from developing further devastating conditions in periodontal infections. The use of genetic knockout and immunodeficient mouse strains has shown that the acquired immune response, in particular, $CD4^+$ T-cells plays a pivotal role in controlling the ongoing infection, the immune/inflammatory responses, and the subsequent host's tissue destruction.

Immune thrombocytopenic purpura(ITP) is an autoimmune disease characterized by increased peripheral platelet destruction due to antibody to platelet, which results in thrombocytopenia and cutaneous or mucosal bleeding. Bleeding generally occurs when platelet counts fall to less than $20,000/{\mu}L$. Children affected with ITP are usually healthy prior to the onset of the disease and typically present suddenly after a viral infection or insidiously with progressive petechiae, bruising, or purpura. In most cases the disease is self-limited; approximately 80% of children recover by 6 months after diagnosis, with or without treatment. Children with thrombocytopenia persisting for more than 6 months are defined as having chronic ITP. Clinical manifestations, diagnosis, laboratory findings, differential diagnosis and various treatment modalities are reviewed.

Because nonalcoholic steatohepatitis can progress towards cirrhosis even in children, early detection of hepatic fibrosis and accurate diagnosis of nonalcoholic fatty liver disease (NAFLD) are important. Although liver biopsy is regarded as the gold standard of diagnosis, its clinical application is somewhat limited in children due to its invasiveness. Noninvasive diagnostic methods, including imaging studies, biomarkers of inflammation, oxidative stress, hepatic apoptosis, hepatic fibrosis, and noninvasive hepatic fibrosis scores have recently been developed for diagnosing the spectrum of NAFLD, particularly the severity of hepatic fibrosis. Although data and validation are still lacking for these noninvasive modalities in the pediatric population, these methods may be applicable for pediatric NAFLD. Therefore, noninvasive imaging studies, biomarkers, and hepatic fibrosis scoring systems may be useful in the detection of hepatic steatosis and the prediction of hepatic fibrosis, even in children with NAFLD.
