Through a consideration of the contralateral collateral needling(繆刺) from "Neijing", the conclusions are as follows. The contralateral collateral needing is defined as a disordered state, and also as the pricking bloodletting method. Unlike the seasonal deficiency pathogen(虛邪), which are affected by the four seasons, the subject of the contralateral collateral needling is the extra pathogen(奇邪), which is the cause of the extra disease(奇病), therefore the treatment should be different from the general. The contralateral collateral needling is generally used when a pain is generated from the veins(絡) by an external pathogen(邪). However, it can be used as the treatment for an emotional disorder, such as flight or sorrow, or a body constituent(身形) disorder caused by internal parts of the five viscera. Although the contralateral collateral needling(繆刺) and the contralateral meridian needling(巨刺) share the left and right cross treatment(右取左, 左取右) in common, but they are different in every aspect, as the causes, transmutation, location, and feature of disease, relation of qi and blood, and location and method of needling(刺鍼). The medical procedure of the contralateral collateral needling is collateral needling(刺絡) the parts of blood collaterals(血絡) or bruising(痏) well points(井穴) of the end of the both sides of limbs, and using the left and right cross treatment when the former methods are not making any progress. The symptoms of contralateral collateral needling are head, chest, and abdomen pains, and they are treated at the end of the limbs. The bloodletting method(刺絡法), extracting a little amount of blood at well points or blood collaterals, or the collateral vessel pricking therapy(瀉血法), extracting a lot of blood by using cupping(附缸), for example, are contemporary successions of the collateral needling(絡刺), the leopard-spot needling(豹文刺), and the contralateral collateral needling.
Avian trichomoniasis caused by Trichomonas gallinae is a serious protozoan disease worldwide. The domestic pigeon (Columba livia domestica) is the main host for T. gallinae and plays an important role in the spread of the disease. Based on the internal transcribed spacers of nuclear ribosomal DNA of this parasite, a pair of primers (TgF2/TgR2) was designed and used to develop a PCR assay for the diagnosis of T. gallinae infection in domestic pigeons. This approach allowed the identification of T. gallinae, and no amplicons were produced when using DNA from other common avian pathogens. The minimum amount of DNA detectable by the specific PCR assay developed in this study was 15 pg. Clinical samples from Guangzhou, China, were examined using this PCR assay and a standard microscopy method, and their molecular characteristics were determined by phylogenetic analysis. All of the T. gallinae-positive samples detected by microscopic examination were also detected as positive by the PCR assay. Most of the samples identified as negative by microscopic examination were detected as T. gallinae positive by the PCR assay and were confirmed by sequencing. The positive samples of T. gallinae collected from Guangzhou, China, were identified as T. gallinae genotype B by sequencing and phylogenetic analyses, providing relevant data for studying the ecology and population genetic structures of trichomonads and for the prevention and control of the diseases they cause.

Purpose: Adult Korean patients on chronic dialysis have a 9-year survival rate of 50%, with cardiovascular problems being the most significant cause of death. The 2011 annual report of the North American Pediatric Renal Trials and Collaborative Studies group reported 3-year survival rates of 93.4% and relatively poorer survival in younger patients. Methods: In this study, we have reviewed data from Korean Pediatric Chronic Kidney Disease Registry from 2002 to 2010 to assess survival rates and causes of death in Korean children on chronic dialysis. Results: The overall estimated patient survival rates were 98.4%, 94.4%, and 92.1% at 1, 3, and 5 years, respectively. No significant difference was observed in survival rates between patients on peritoneal dialysis and those on hemodialysis. Patients for whom dialysis was initiated before 2 years of age (n=40) had significantly lower survival rates than those for whom dialysis was initiated at 6-11 years of age (n=140). In all, 26 patients had died; the mortality rate was 19.9 per 1,000 patient years. The most common causes of death were infections and comorbidities such as malignancy and central nervous system (CNS) or liver diseases. Conclusion: The outcomes observed in this study were better than those observed in adults and comparable to those observed in pediatric studies in other countries. To improve the outcomes of children on chronic dialysis, it is necessary to prevent dialysis-related complications such as infection, congestive heart failure, or CNS hemorrhage and best control treatable comorbidities.

Collapsing glomerulopathy (CG) has become an important cause of end-stage renal disease (ESRD). First delineated from other proteinuric glomerular lesions in the 1980s, CG is now recognized as a common, distinct pattern of proliferative parenchymal injury that portends a rapid loss of renal function and poor responses to empirical therapy. The first cases in the literature trace back to human-immunodeficiency-virus(HIV)-negative patients who underwent biopsy in 1979. A 45-year-old male patient complained of hematuria and proteinuria eight years ago. He showed an abrupt serum creatinine increase from 1.75 to 2.65 mg/dL in the last preceding months. Afterwards, his serum creatinine progressively increased up to 6.82 mg/dL. Moreover, his 24 h urine protein level was determined to have reached 6,171 mg/day, as opposed to 670 mg/day a year earlier. Consequently, renal biopsy was performed, and its result showed collapsing glomerulopathy, compatible with the diagnosis. He has undergone continuous ambulatory peritoneal dialysis as renal replacement therapy. Thus, it is reported herein that a patient clinically diagnosed with chronic kidney disease eight years ago showed a sudden renal-function decrease and was clinicopathologically diagnosed with collapsing glomerulopathy based on the results of his renal biopsy.
Gastric cancer (GC) is the fourth most common cause of cancer-related death globally. The classification of advanced GC (AGC) according to molecular features has recently led to effective personalized cancer therapy for some patients. Specifically, AGC patients whose tumor cells express high levels of human epidermal growth factor receptor 2 (HER2) can now benefit from trastuzumab, a humanized monoclonal Ab that targets HER2. However, patients with HER2negative AGC receive limited clinical benefit from this treatment. To identify potential immune therapeutic targets in HER2negative AGC, we obtained 40 fresh AGC specimens immediately after surgical resections and subjected the CD45+ immune cells in the tumor microenvironment to multi-channel/multi-panel flow cytometry analysis. Here, we report that HER2 negativity associated with reduced overall survival (OS) and greater tumor infiltration with neutrophils and non-classical monocytes. The potential pro-tumoral activities of these cell types were confirmed by the fact that high expression of neutrophil or non-classical monocyte signature genes in the gastrointestinal tumors in The Cancer Genome Atlas, Genotype-Tissue Expression and Gene Expression Omnibus databases associated with worse OS on Kaplan-Meir plots relative to tumors with low expression of these signature genes. Moreover, advanced stage disease in the AGCs of our patients associated with greater tumor frequencies of neutrophils and non-classical monocytes than early stage disease. Thus, our study suggests that these 2 myeloid populations may serve as novel therapeutic targets for HER2negative AGC.
Objectives : The Purpose of this study is to apply an oral health education program to the high school students, to analyze their oral health knowledge and changes of behaviors, and to examine oral health education for effective, thus using all of those results as the basic data for developing materials on their oral health education. Methods : The study was conducted on the freshmen and women of M high student in Seoul City. They were in total 85 student, consisting of 77 of male student(90.6%) and 8 of female student(9.4%). Knowledge survey contained 38 questions including such as dental common knowledge, dental caries, and periodontal disease, while behaviors survey did 24 questions including such as tooth-brushing, brush selection and management, and prevention of oral disease. Results : First, oral health education had brought to improve oral health knowledge for high school students. Second, even with the improvement of oral health behaviors through the education, there was not statistically significant on behaviors such as the regular checkups and the usage of dental floss. And third, the students in general were satisfied with the oral health education. Conclusions : First, the oral health education being conducted in kindergarten and elementary school should be continued or expanded into the adolescence. Second, the oral health education should be focused efficiently on the learning objective demanding for a change of behavior through the repeated education, for which the education that is right for the high school students should be done. And third, for the effective oral health education in high school, the media that could cause interests should be developed.
Background: Pediatric deep neck infection can cause critical complications in that they are seldom able to verbalize symptoms or cooperate with physical examination. The objective of this study is to identify the clinical characteristics according to age. Material and Method: A retrospective study was performed on 26 cases with pediatric deep neck infection during 12 years. Patients were classified infancy group (1-7 yr, 19.2%), preschool age group (7-15 yr, 30.8%) and school age group (15 yr-, 50%). We analyzed the age, sex, sites of abscess, predisposing factors, symptoms and compared onset, hospital date, laboratory and outcomes at each group. Results: In pediatric patients with deep neck infection, the age distribution was 18 males (69.2%) and 8 females (30.8%), the mean age was 7.4 years. The most common infection site was the anterior cervical triangle and submandibular space (19.2%). The most commonly known associated preceding disease was upper viral infection (34.6%), but we could not find the preceding diseases in most of cases (50%). Neck swelling (69.2%) was the most frequent symptom. The mean age of patients who performed neck CT was 8.23 years and neck US was 2.75 years. The younger patients were preferred to perform the neck US than the neck CT (p=0.022). The mean time from disease onset to admission was 9 days in the infancy, 5.5 days in the preschool aged and 5 days in the school aged group. The surgical treatment was performed in 30.8% of school aged, 62.5% of preschool aged and 100% of infancy group. Surgical treatment was preferred to younger patients (p=0.026). Conclusion: Abscess sites, size, and antibiotics susceptibility and especially patient age should be carefully considered in treating pediatric deep neck infection.
Objectives: Human rhinoviruses (HRVs) are the major cause of the common cold. Currently there is no registered, clinically effective, antiviral chemotherapeutic agent to treat diseases caused by HRVs. In this study, the antiviral activity of dexamethasone (DEX) against HRV1B was examined. Methods: The anti-HRV1B activity of DEX was assessed by sulforhodamine B assay in HeLa cells, and by RT-PCR in the lungs of HRV1B-infected mice. Histological evaluation of HRV1B-infected lungs was performed and a histological score was given. Anti-HRV1B activity of DEX via the glucocorticoid receptor (GCR)-dependent autophagy activation was assessed by blocking with chloroquine diphosphate salt or bafilomycin A1 treatment. Results: In HRV1B-infected HeLa cells, treatment with DEX in a dose-dependent manner, resulted in a cell viability of > 70% indicating that HRV1B viral replication was reduced by DEX treatment. HRV1B infected mice treated with DEX, had evidence of reduced inflammation and a moderate histological score. DEX treatment showed antiviral activity against HRV1B via GCR-dependent autophagy activation. Conclusion: This study demonstrated that DEX treatment showed anti-HRV1B activity via GCR-dependent autophagy activation in HeLa cells and HRV1B infected mice. Further investigation assessing the development of topical formulations may enable the development of improved DEX effectiveness.
Objectives: An outbreak of hepatitis A occurred at a residential facility for the disabled in July 10, 2011. This investigation was carried out to develop a response plan, and to find the infection source of the disease. Methods: A field epidemiologist investigated the symptoms, vaccination histories, living environments, and probable infection sources with 51 residents and 31 teachers and staff members. In July 25, 81 subjects were tested for the hepatitis A virus antibody, and specimens of the initial 3 cases and the last case were genetically tested. Results: Three cases occurred July 10 to 14, twelve cases August 3 to 9, and the last case on August 29. Among the teachers and staff, no one was IgM positive (on July 25). The base sequences of the initial 3 and of the last case were identical. The vehicle of the outbreak was believed to be a single person. The initial 3 patients were exposed at the same time and they might have disseminated the infection among the patients who developed symptoms in early August, and the last patient might have, in turn, been infected by the early August cases. Conclusions: The initial source of infection is not clear, but volunteers could freely come into contact with residents, and an infected volunteer might have been the common infection source of the initial patients. Volunteers' washing their hands only after their activity might be the cause of this outbreak. Although there may be other possible causes, it would be reasonable to ask volunteers to wash their hands both before and after their activities.

Mutations in leucine-rich repeat kinase 2 (LRRK2) are the most common genetic cause of Parkinson's disease (PD). LRRK2 contains a functional kinase and GTPase domains. A pathogenic G2019S mutation that is the most prevalent among the LRRK2 mutations and is also found in sporadic cases, increases its kinase activity. Therefore, identification of LRRK2 kinase substrates and the development of kinase inhibitors are under intensive investigation to find PD therapeutics. Several recent studies have suggested members of Rab proteins, a branch of the GTPase superfamily, as LRRK2 kinase substrates. Rab proteins are key regulators of cellular vesicle trafficking. Among more than 60 members of human Rab proteins, Rab3, Rab5, Rab8, Rab10, Rab12, Rab29, Rab35, and Rab43 have been identified as LRRK2 kinase substrates. However, most studies have used human embryonic kidney (HEK) 293T cells overexpressing LRRK2/Rab proteins or murine embryonic fibroblast (MEF) cells which are not relevant to PD, rather than neuronal cells. In this study, we tested whether Rab proteins are phosphorylated by LRRK2 in astroglia in addition to neurons. Among the various Rab substrates, we tested phosphorylation of Rab10, because of the commercial availability and credibility of the phospho-Rab10 (pRab10) antibody, in combination with a specific LRRK2 kinase inhibitor. Based on the results of specific LRRK2 kinase inhibitor treatment, we concluded that LRRK2 phosphorylates Rab10 in the tested brain cells such as primary neurons, astrocytes and BV2 microglial cells.
