  • PET of the cerebral metabolic rate of glucose is increasingly used to support the clinical diagnosis in the examination of patients with suspected major neurodegenerative disorders, such as Alzheimer's disease. $^{18}F-FDG$ PET has been reported to have high diagnostic performance, especially, very high sensitivity in the diagnosis and clinical assessment of therapeutic efficacy. According to clinical research data hitherto, $^{18}F-FDG$ PET is expected to be an effective diagnostic tool in early and differential diagnosis of Alzheimer's disease. Since 2004, Medicare covers $^{18}F-FDG$ PET scans for the differential diagnosis of fronto-temporal dementia (FTD) and Alzheimer's disease (AD) under specific requirements; or, its use in a CMS approved practical clinical trial focused on the utility of $^{18}F-FDG$ PET in the diagnosis or treatment of dementing neurodegenerative diseases.

  • Head and neck cancer is the sixth most common type of human cancer worldwide. Squamous cell carcinoma is the most common cancer of the head and neck. Since $^{18}F-FDG$ PET is very sensitive to detecting squamous cell carcinoma, it has been widely used in patients with head and neck cancers for initial staging, management of recurrent cancers, and therapeutic monitoring. According to clinical research data, $^{18}F-FDG$ PET is expected to be a very helpful diagnostic tool in the management of head and neck cancer.

  • The examination of small bowel in Crohn's disease (CD) is very important. Capsule endoscopy (CE) has been recognized as a good tool for evaluation of small bowel. The capsule placement is achieved endoscopically for Children not to swallow capsule. CE is superior to any other modalities for examination of small-bowel. The large portion of pediatric patients with known CD were found with CE to have more extensive and newly diagnostic small-bowel disease. All of them had therapeutic changes. The most side effect of CE is capsule retention. The capsule retention rate in pediatric CD is about 7.3%. The patency capsule helps to predict the possibility of capsule retention. For the improving of the diagnostic accuracy, the experience of more than 20 readings of CE is needed.

  • Peptide imaging is a new diagnostic modality in nuclear medicine. $^{111}In$-pentetreotide ($Octreoscan^R$) is the first commercially available peptide radiopharmaceutical. This review article presents the results of previous studies using $^{111}In$-pentetreotide for several disease states, including neuroendocrine tumors, breast cancer and malignant lymphoma. The use of hand-held probe during surgery and the preliminary results of radiotherapy using radiolabeled somatostatin analogues are also reviewed. It can be concluded that somatostatin receptor scintigraphy is a promising diagnostic tool for localizing primary tumors that express receptors for somatostatin, staging secondary spread of tumor tissue, following up after therapy and identifying patients who may benefit from therapy with unlabelled or radiolabeled octreotide. The somatostatin receptor imaging will stimulate the development of new radiopharmaceuticals for other receptors and enhance the therapeutic use of radiolabeled peptides.

  • Xenograft models of human cancer play an important role in the screening and evaluation of candidates for new anticancer agents. The models, which are derived from human tumor cell lines and are classified according to the transplant site, such as ectopic xenograft and orthotopic xenograft, are still utilized to evaluate therapeutic efficacy and toxicity. The metastasis model is modified for the evaluation and prediction of cancer progression. Recently, animal models are made from patient-derived tumor tissue. The patient-derived tumor xenograft models with physiological characters similar to those of patients have been established for personalized medicine. In the discovery of anticancer drugs, standard animal models save time and money and provide evidence to support clinical trials. The current strategy for using xenograft models as an informative tool is introduced.

  • Endoscopic ultrasound in the diagnosis of esophageal carcinoma is an indispensable procedure, not only to discuss the preoperative staging of the lesion, but also to evaluate the therapeutic effect of chemo-radiation therapy. The recent increase in the incidence of superficial esophageal cancer and promising developments in potentially curative endoscopic therapies have placed EUS to a central position in decision making. Recent data have called into question the staging accuracy of EUS to distinguish mucosal from submucosal lesions, particularly in patients with early disease. In those cases, diagnostic endoscopic resection may be useful for staging and curative in superficial lesions. Nonetheless, EUS has been regarded as the most accurate staging tool and should be performed to identify potential candidates for endoscopic resection.

  • Periodontitis is an inflammatory disorder of the periodontium and is characterized by destruction of the tooth supporting tissues, mediated by the upregulation of synthesis and release of a variety of pro-inflammatory factors. Inflammatory cytokines and prostaglandins upregulate RANKL and its subsequent binding to RANK stimulates osteoclast formation, resorption activity, and survival. In our present study, we investigated the effects of HP08-0111, composed of Coptis japonica (Thunb.) Makino, vitamin C and vitamin E, upon inflammatory responses, osteoclastogenesis and alveolar bone loss. HP08-0111 decreased the expression of IL-1$\beta$ and COX2 on LPS-induced RAW 264.7 cells and inhibited osteoclast-specific genes such as c-Fos, MMP-9, and TRAP. HP08-0111 also exhibited protective effects against alveolar bone loss in rats with ligature-induced periodontitis. Our results suggest that HP08-0111 is potentially an important therapeutic tool for the treatment of disorders associated with bone loss such as periodontitis.

  • Intestinal lymphangiectasia is a rare disease which is causing protein-losing enteropathy. Treatment of intestinal lymphangiectasia can be a challenge for clinicians because of the lack of specific guidelines regarding pharmacological indications. We sought to introduce a diagnostic approach and suggest guidelines for treatment. After exclusion of secondary intestinal lymphangiectasia, magnetic resonance lymphangiography is a promising tool for the assessment of abnormal lymphatic lesions in primary intestinal lymphangiectasia. Determining the extent of the lesion provides direction for treatment options. Focal short-segment intestinal lymphangiectasia can be treated via intestinal resection or radiologic embolization after dietary therapy failure. Diffuse intestinal lymphangiectasia and extensive lymphangiectasia should be treated with several drugs with a full understanding of their mechanisms.

  • Clustered regularly interspaced short palindromic repeats and CRISPR-associated protein 9 (CRISPR-Cas9) is an ancient prokaryotic defense system that precisely cuts foreign genomic DNA under the control of a small number of guide RNAs. The CRISPR-Cas9 system facilitates efficient double-stranded DNA cleavage that has been recently adopted for genome editing to create or correct inherited genetic mutations causing disease. Congenital heart disease (CHD) is generally caused by genetic mutations such as base substitutions, deletions, and insertions, which result in diverse developmental defects and remains a leading cause of birth defects. Pediatric CHD patients exhibit a spectrum of cardiac abnormalities such as septal defects, valvular defects, and abnormal chamber development. CHD onset occurs during the prenatal period and often results in early lethality during childhood. Because CRISPR-Cas9-based genome editing technology has gained considerable attention for its potential to prevent and treat diseases, we will review the CRISPR-Cas9 system as a genome editing tool and focus on its therapeutic application for CHD.

  • The growing use of laparoscopy in elective surgery has led to its increase utilization in emergency surgery. However, the employment of laparoscopy in abdominal trauma is still unusual. Here in we report a case of a patient with blunt abdominal trauma that resulted in a combination of exceptional traumatic lesions, diaphragmatic and bladder lacerations. Both injuries were diagnosed and successfully resolved by laparoscopy. The report of this type of lesions and resolution is extremely rare, being this the second case described in the international literature. This article intends to show that laparoscopy may not only be used as a diagnostic tool, but also as a therapeutic instrument in selected cases of blunt abdominal trauma.
