  • Objective: Excision repair cross-complementing group 6 (ERCC6) is a major component of the nucleotide excision repair pathway that plays an important role in maintaining genomic stability and integrity. Several recent studies suggested a link of ERCC6 polymorphisms with susceptibility to various cancers. However, the relation of ERCC6 polymorphism with gastric cancer (GC) risk remains elusive. In this sex- and age-matched case-control study including 402 GC cases and 804 cancer-free controls, we aimed to investigate the association between a potentially functional polymorphism (rs1917799 T>G) in the ERCC6 regulatory region and GC risk. Methods: The genotypes of rs1917799 were determined by Sequenom MassARRAY platform and the status of Helicobacter pylori infection was detected by enzyme-linked immunosorbent assay. Odd ratios (ORs) and 95% confidential interval (CI) were calculated by logistic regression analysis. Results: Compared with the common TT genotype, the ERCC6 rs1917799 GG genotype was associated with increased GC risk (adjusted OR=1.46, 95%CI: 1.03-2.08, P=0.035). When compared with (GT+TT) genotypes, the GG genotype also demonstrated a statistical association with increased GC risk (adjusted OR=1.38, 95%CI: 1.01-1.89, P=0.044). This was also observed for the male subpopulation (GG vs. TT: adjusted OR=1.71, 95%CI: 1.12-2.62, P=0.013; G allele vs. T allele: adjusted OR=1.32, 95%CI: 1.07-1.62, P=0.009). Genetic effects on increased GC risk tended to be enhanced by H. pylori infection, smoking and drinking, but their interaction effects on GC risk did not reach statistical significance. Conclusions: ERCC6 rs1917799 GG genotype might be associated with increased GC risk in Chinese, especially in males.

  • Objective: To determine the expression of E-cadherin, ${\beta}$-catenin, and transcription factor 4 (TCF4) proteins in gastric diseases with relation to Helicobacter pylori infection. Methods: A total of 309 patients including 60 with superficial gastritis (SG), 57 with atrophic gastritis (AG) and 192 with gastric cancer (GC), were enrolled. The expression of E-cadherin, ${\beta}$-catenin, TCF4 proteins in the gastric mucosa was detected by immunohistochemistry and H. pylori infection by immunohistochemistry and PCR. Results: The expression rates of E-cadherin were significantly higher in SG and AG than in GC (P<0.01), while those of ${\beta}$-catenin in the nucleus were significantly lower in SG and AG than in GC (P<0.05). In GC cases, the expression rates of E-cadherin, ${\beta}$-catenin and TCF4 were significantly higher in the intestinal type than in the diffuse type (P<0.05). In GC patients, the expression rate of E-cadherin was significantly higher in the presence of H. pylori than in the absence of infection (P=0.011). Moreover, the expression level of TCF4 and ${\beta}$-catenin protein was significantly higher in the nucleus and cytoplasm in H. pylori positive than in H. pylori negative GC patients, especially in those with the intestinal type (all P < 0.05). Conclusion: The expression of E-cadherin and ${\beta}$-catenin progressively decreases during the process of GC tumorigenesis, while overexpression of TCF4 occurs. H. pylori infection is associated with a significant increase in the expression of E-cadherin and ${\beta}$-catenin in the cytoplasm and nucleus in GC patients, especially those with the intestinal type.

  • Objectives This study aimed to provide a basis for applying Korean medical treatment for childhood anorexia in clinical practice by examining Korean medical etiology, pattern differentiation, and treatment, and focusing on research articles on Chinese medicine. Methods Articles on Chinese medicine related to childhood anorexia published before November 4, 2021, in the China National Knowledge Infrastructure (CNKI), were analyzed. The etiology, pattern differentiation, and Chinese medical treatment were summarized. Results Of a total of 73 studies, 13 were randomized controlled trials (RCT), 32 were case studies, and 28 were review papers. The most common Chinese medical etiology of childhood anorexia was emotional instability, and the western medical etiology was problems with diet and lifestyle. The most frequently reported pattern differentiations were spleen-stomach-qi deficiency (脾胃氣虛), stomach-yin deficiency (胃陰不足), and spleen failing in transportation syndrome (脾失健運). The most frequent prescriptions were modified Yangwijeungaektang (养胃增液湯加減), Samryongbakchulsan (蔘苓白术散加减), and Ekongsan (異功散加減). As frequntly used tuina acupoints, Naepalgwae (内八卦), Joksamli (足三里), and Bigyeong (脾經) were mentioned. Conclusions This study analyzed the etiology, pattern differentiation, and Korean medical treatment of anorexia in children. Based on this study, standardization and well-designed clinical studies on Korean medical treatments for childhood anorexia can be expected in the future.

  • Status epilepticus is a medical emergency, so that rapid and vigorous treatment is required to prevent neuronal damage and systemic complication. Status epilepticus is generally defined as a continuous or intermittent seizure or an unconscious condition after the onset of seizure, lasting for 30 minutes or more. We report here the outcome of status epilepticus. We retrospectively reviewed medical record of 15 patients who were diagnosed with status epilepticus at the Asan Medical Center from January 2003 to February 2004. This outcome was evaluated considering various factors such as age of patients, history of seizures, neurologic impairment, etiology, mortality, return to baseline and initial electroencephalogram (EEG) findings. The range of age was between 1 to 79 years old and the longest duration of treatment was 118 days. Most patients were treated by using pentobarbital, midazolam, phenobarbital and other antiepileptic drugs. The overall mortality was 5 (33%) out of 15 patients. The mortality was related to etiology, underlying other medical conditions and initial EEG findings. 5 (55%) out of the 9 patients with acute etiology, 5 (71%) out of the 7 patients with a multifocal or burst-suppression EEG activity, and 3 (60%) out of the 5 patients with other medical disease were related to mortality. This data demonstrate high mortality due to status epilepticus. Mortality is related to etiology, other medical conditions and abnormalities on the initial EEG.

  • Early onset scoliosis (EOS) describes the onset of scoliosis before the age of 10 years and is associated with significant health risks. Compared to adolescent idiopathic scoliosis, studies on the etiology of EOS in children are more common. EOS includes inhomogeneous groups of patients, and the etiology of EOS may be congenital, neuromuscular, syndromic, or idiopathic. The identification of the molecular etiology underlying patients with EOS has been increasing. This could provide valuable information for optimizing the management and care of these children. In this review, EOS was reviewed from a medical genomic perspective.

  • Anterior spacing is one of the interesting phenomena in clinical orthodontics and presents difficulties in determining the etiology and the retention method. Only through the careful examination can orthodontists reach the correct diagnosis and treatment plan and every orthodontist should get rid of the cause to obtain good results. The author considered about the treatment and the retention method of the anterior spacing according to etiology and presented two eases of anterior spacing. In the first ease, the etiology was simple arch length discrepancy with excessively protruded anteriors. In the second ease, the etiology was the same as the above but the patient had the tongue thrusting habit. Both the eases showed the thin fibrous tissue bands between the upper central incisors but only the second case was thought to be associated with this tissue. The permanent retention loop which is non-surgical was applied to the ease and the results were acceptable.
