Background: Gastric cancer (GC) is the fifth most common cancer worldwide. Since development is usually asymptomatic, it is generally diagnosed at an advanced stage. The value of screening in patients with nonspecific symptoms for GC is controversial. Aim: The study aimed to evaluate whether hematological parameters (platelet count (PC), mean platelet volume (MPV), MPV/PC ratio, red blood cell distribution width (RDW), neutrophil to lymphocyte ratio (NLR), and platelet to lymphocyte ratio (PLR)) are useful markers to differentiate between gastric cancer patients and healthy individuals. Materials and Methods: Sixty-one patients with gastric cancer and sixty-one healthy individuals were enrolled to the survey and retrospective analysis of selected blood parameters were performed. Results: The mean values of PC, MPV, RDW, NLR, and PLR were significantly higher in GC patients compared to the control group. No statistical differences were observed in MPV/PC ratios. Likewise, no significant statistical differences were revealed in values of blood parameters among TNM stage groups. The RDW showed the highest diagnostic specificity and sensitivity. Conclusions: Hematological parameters: PC, MPV, RDW, NLR, PLR have diagnostic power and can discriminate patients with gastric cancer from patients without cancer. Blood parameters compared with clinical symptoms might alert physicians and patients and lead to performancce of upper gastrointestinal endoscopy, the gold standard in gastric cancer screening and therebly increase the early detection of cancer.

The recent increased interest in hygiene has led to the use of a variety of detergents everyday life. Accordingly, accidents occur frequently, but proper precautions or treatments have not yet been established for these occasions. The patient in this case had accidentally ingested basic detergent, after mistaking it for a drink. This had caused acid reflux swallowing distress. Treatment in a western medical hospital had resulted in improvement in inflammation, as observed with an esophageal endoscopy test, but the patient still found it almost impossible to drink or eat. Following treatment with herbal medicine and acupuncture, the patient’s food intake increased and the pain and dysphagia were diminished. We cannot generalize based only on this one case study, so further studies are needed.

Objective: The purpose of this study was to investigate the effect of combined therapy with Banhasasim-tang and conventional treatment for atrophic Gastritis. Methods: The study collected data of clinical studies of combined therapy with Banhasasim-tang and conventional treatment for atrophic gastritis. Electronic databases were used, including PubMed, Cochrane, CNKI, Wanfang, CINII, J-stage, NDSL, and OASIS. The main search terms included such as "Atrophic Gastritis", "Banhasasim-tang", "BanXia Xiexin Tang". This study only included randomized controlled trials (RCTs) that adopted combined therapy with Banhasasim-tang and conventional treatment for atrophic gastritis. Results: A total of 18 RCTs were selected. They all adopted combined therapy with Banhasasim-tang and conventional treatment for atrophic gastritis. In all the studies, the intervention group significantly improved the score of effective rate, and in the 8 studies, Hp negative conversion rate was significantly improved when Banhasasim-tang was taken. Conclusion: Through the analysis of 18 RCTs, we found Banhasasim-tang combined with conventional therapy were more effective in the positive performance of atrophic gastritis than conventional therapy single contribution. However, due to the low quality of the selected studies and the lack of endoscopy, biopsy, follow-up observation, so there is a slight insufficient to prove its conclusion. Therefore, we hope that more systematic and diverse clinical studies will be conducted.

Most cases of mucosa-associated lymphoid tissue (MALT) lymphoma occur in adults. MALT lymphoma is very rare in children. Helicobacter pylori (H. pylori) infection is known to be an important etiologic factor predisposing to the development of gastric MALT lymphoma. A 12-year-old girl was admitted because of intermittent abdominal pain occurring over the preceding 2 years. Nodular gastritis of the stomach was demonstrated on endoscopy. H. pylori infection was confirmed using the rapid urease test and histopathology. Histopathological examination of gastric biopsy specimens revealed lymphoepithelial lesions pathognomonic of MALT lymphoma, and immunohistochemical staining for CD20 was diffusely positive. Therefore, the patient was diagnosed with gastric MALT lymphoma. Clinical manifestations and histopathologic findings compatible with MALT lymphoma improved with the eradication of H. pylori infection. We report a case of primary gastric MALT lymphoma in a child, associated with H. pylori infection and presenting as nodular gastritis.

In this study, air scouring cleaning was selected and applied among 5 small blocks (S1~S5) in domestic S cities to analyze the cleaning effect of particles causing discoloration. In order to identify the cleaning effect, 10 locations were selected as water quality investigation point, such as the stagnant or water mains ends. Removal of solids, variation of particle components, weight and concentration were analyzed. And the level of the cleanness of the surface inside water mains using endoscope was investigated. As a result of analysis, the solids discharged after cleaning were mainly sand and gravel, pieces related to pipe materials, and corrosion products. As a result of analyzing the concentrated particles of the filter before and after cleaning, it was found that the change in discoloration on the filter was large. In addition, as a result of comparing the weight and the concentration of the particles, it was found that the particles causing discoloration were significantly removed after cleaning. From the results of the endoscopy, it was confirmed that most of the precipitated and accumulated dark yellow discoloration matters inside water mains were removed through cleaning. Therefore, it seems that the particles causing discoloration in water decreased after cleaning. Therefore, it is expected that, if properly cleaning was applied, matters that cause discoloration can be removed from the water mains, and customer's complaints can also be reduced through water quality improvement.

There are a lot of dental emergency situations and accidental aspiration or ingestion of a dental instrument is one of the common accidents in dental practice especially on disabied or pediatric patient with negative behavior. Most of ingested foreign bodies pass through the gastrointestinal tract spontaneously, but some of them (about 20%) need endoscopic or surgical removal. This is a case of an accident during the treatment of a 18 months male patient with caries of anterior deciduous teeth. During the treatment, the gauze was used by waterproofing instead of a rubber dam. #4 round bur (approximately 2.2cm long) which was put on the tray was cling to the gauze and the bur was fell into the patient's throat. The bur was 2.2cm long and very sharp so it could not be passed spontaneously through the pylorus, so we tried to remove the bur by esophagogastroduodenoscopy. Endoscopic removal of foreign bodies in the upper gastrointestinal tract is an effective and safe procedure.

Purpose: Many surgical methods for reconstruction of orbital floor fracture have been reported, which include subciliary approach, transconjunctival approach, transantral and transnasal endoscopic approach, etc. The purpose of this study is to demonstrate a surgical technique and analyze the results of transnasal endoscopic approach with Foley catheter ballooning without implantation of artificial surgical material through subciliary approach. Methods: Between February 2007 and November 2010, 29 orbital floor fracture patients, who had no herniated muscles through bone fragments, were treated through transnasal endoscopic approach with Foley catheter ballooning. Under the endoscopic view, the operator identified the opening of maxillary sinus. After widening of the opening using forceps, the operator reduced the fragmented bone with curved suction tip. Thereafter, 18-Fr Foley catheter was inserted. Four weeks after the operation, the catheter was removed. Results: Preoperatively, 6 patients had diplopias, 4 patients had limitations of extraocular motions and 3 patients had enophthalmos. After removal of the Foley catheter 4 weeks after the operation, 2 patients had diplopias, 1 patient had a limitation of extraocular motion, 1 patient has an enophthalmos and 1 patient had numbness on the cheek. These symptoms were resolved about 6 months after the surgery. Conclusion: The operative technique of Foley catheter ballooning through transnasal endoscopic approach without implantation of the artificial surgical material through subciliary approach can be considered one of the appropriate techniques for orbital floor fracture.

This paper presented an image reconstruction method based on the original capsule endoscopy photos yielding a 2-D image for faster diagnosis proposes. The proposed method constructed a 3-D intestine model using the massive images obtained from the capsule endoscope. It merged all images and completed a 3-D model of an intestine. This 3-D model was reformed as a 2-D plane image showing the inner side of the entire intestine. The proposed image composition was evaluated by the 3-D simulator, OpenGL. This approach was demonstrated successfully. A physician can find the location of a disease at a glance because the composite image provided an easy-to-understand view to show the patient's intestine and thereby shorten diagnosis time.

WBAN has received great attention recently due to its versatile applicability. In this paper, antennas suitable for WBAN communication depending on the locations of mobile devices and the manufacturing of a human equivalent phantom are introduced. The effect of the body on the communication performance is largely dependent on the locations of devices. Specifically, the radiation and return loss characteristics of the antenna are greatly influenced by the characteristics of a medium existing in the near-field of an antenna. Thus, the proper WBAN antenna design is important in establishing a successful communication link between the transceivers. To consider the effect of the body on the antenna performance, the human equivalent phantom is also important factor in the WBAN antenna design and measurement. In introduction, categorization of the WBAN communication channel is introduced and antenna characteristics required for each communication channel are described. In the main subject section, several WBAN antenna design examples along with the implementation of the human equivalent phantom are discussed. In conclusion, the factors, which have to be considered in the design process, and future research are mentioned.

Immunoglobulin G4-related disease (IgG4-RD) is an immune-mediated fibro-inflammatory disorder characterized by specific pathological findings and elevated serum IgG4 level. IgG4-RD in the stomach is rare, and occasionally diagnosed as gastric subepithelial tumor (SET) by endoscopy or computed tomography scan. Two female patients in the age group of 40-50 years were diagnosed with 4 cm sized gastric SET. One underwent laparoscopic gastric wedge resection. Another one had a history of subtotal gastrectomy for early gastric cancer and idiopathic thrombocytopenic purpura with oral steroids administration. She underwent a completion total gastrectomy with splenectomy for the gastric SET and ITP. The pathology showed storiform fibrosis, and IgG4 was positive in immunohistochemistry (IHC) stain. IgG4-RD is known as a medical disease that could be treated with oral steroids. The difficulty in preoperative diagnosis of the disease occasionally causes unnecessary gastric resection. Thus, preoperative diagnostic methods for IgG4-RD such as deep biopsy with IHC stain or magnetic resonance imaging are needed.
