  • The Hippo pathway was originally discovered in Drosophila by genetic screening and it has been shown to be conserved in various organisms including human. Until now, the essential roles of Hippo pathway in regulating cell proliferation, apoptosis, tumorigenesis, and organ size control is extensively studied. Currently, Mats1/2 (Mob1a/1b), one of the important components in Hippo pathway, mutant mice were generated which has abnormal phenotype such as resistance to apoptosis and spontaneous tumorigenesis. Of note, Mats1/2 mutant mice also showed dental malocclusion. Therefore, in this study, we have evaluated the bone phenotype of Mats1/2 mutant mice. Although the mRNA expressions of Mats1 or Mats2 were observed in both osteoclastogenesis and osteoblastogenesis, the increase of Mats1 level was most prominent during osteoblastogenesis. The RANKL-induced osteoclast differentiation from bone marrow-derived macrophages (BMMs) was unaltered upon Mats1/2 mutation; however, the osteoblast differentiation using calvarial pre-osteoblasts was significantly reduced in Mats1/2 mutant mice compare to that of wild type mice. In accordance with in vitro results, Mats1/2 mutant mice showed decreased bone volume as well as increased trabecular separation in ${\mu}CT$ analyses. These results may provide novel prospect of the probable linkage between Hippo pathway and bone homeostasis.

  • Purpose: The purpose of this study was to analyze the cumulative survival rate of dental implants installed with guided bone regeneration (GBR), and also elucidate the factors related with the survival of dental implants. Material and Methods: This retrospective study was conducted on 148 dental implants installed in 76 patients by one specialist (Y.K.) at the Department of Periodontology and Implant Center, Seoul National University Dental Hospital from 2001 to 2010. The cumulative survival rates were obtained by the Kaplan-Meier method. The correlations between various factors and dental implant survival were analyzed by using the log-rank test and Cox proportional hazards model. Results: Among 148 dental implants installed in 76 patients, 8 implants in 7 patients were lost and the cumulative survival rates up to 5-years and 10-years were 97% and 89%, respectively. Gender, smoking status and location of implant were significantly associated with the cumulative survival rate of implants (p < 0.05). Age, history of hypertension and diabetes were not significantly associated with the cumulative survival rate of implants (p > 0.05). Conclusion: The dental implants installed with guided bone regeneration is predictable technique according to the results of cumulative survival rate over 10 years.

  • Objectives: The objective of this study was to review the research trends in the treatment of acupuncture on schizophrenia in traditional Chinese medicine. Methods: Articles in the China National Knowledge Infrastructure (CNKI) from September 2008 to August 2018 were reviewed. The selected articles were evaluated by the Jadad Scale. Results: 11 articles were selected from a total of 33 articles. 1 study was single group before-and-after study while the other 10 studies were randomized controlled trial studies. Chinese Classification of Mental Disorders-3 was most frequently used as a diagnostic criterion. Brief Psychiatric Rating Scale was most commonly used as an outcome measurement. From Jadad Quality Assessment Scale of the 11 articles, the quality of the studies generally was low. Conclusions: BaekHoi (GV20) and YinDang (EX-HN3) are most commonly used in acupuncture treatment. According to this study, acupuncture treatment in addition to western medication on schizophrenia is more effective as compared to the controls. In future, this study could be primary data for development of more clinical research on the treatment of schizophrenia in Korean medicine.

  • Objectives: The purpose of this study was to evaluate the neuroprotective effects of donepezil and 33 kinds of herbal extract combinations in SH-SY5Y cells with $A{\beta}_{25-35}$ treatment. Methods: MTT assay was performed to measure the cell viability of each herbal extract combined with donepezil against $A{\beta}$-induced neurotoxicity. The most active extracts were then subjected to assess the effects on CREB phosphorylation and COX-2 expressions through the western blot analysis. Results: There were eight herbal extracts representing significant increase on the cell viability: 1) Erycibe obtusifolia, 2) Polygonum multiflorum, 3) Polygala tenuifolia, 4) Illicium verum, 5) Santalum album, 6) Loranthus parasticus, 7) Platycladus orientalis, and 8) Zanthoxylum piperitum. Especially, when Santalum album and donepezil were treated together, the phosphorylation of CREB significantly increased and COX-2 protein expression was significantly inhibited. Conclusions: Among the screened herbal extracts, combination treatment of each of the eight herbs and donepezil showed neuroprotective effects in SH-SY5Y cells. Additionally, the combination of Santalum album and donepezil suggested cognitive improvement by up-regulation of p-CREB and down-regulation of COX-2.

  • Objectives: The purpose of this study was to provide clinical evidence to support the use of herbal medicine combined with western medicine for BPSD. Methods: Studies were identified by searching CNKI, Pubmed, EMBASE, Cochrane Library, SCIENCEON, RISS, KMbase, KISS, OASIS. Literature searches of Chinese, English, and Korean databases were performed. Two authors independently extracted the data and evaluated the quality of each study. Results: The literature search identified 203 articles. Of these, 7 were selected for the analysis. The risk of bias in most studies was unclear. The most frequently used diagnostic tools were the NINCDS-ADRDA and DSM-IV. The most commonly used results indicator was NPI. In 6 of the 7 papers, combination treatment (herbal & Western medicine) was statistically significantly more effective than single treatment (Western medicine alone) for BPSD. No significant adverse events were reported. Conclusions: Herbal medicine in combination with Western medicine is more effective for treating BPSD than Western medicine alone. However, the quality of the studies used in this study was uncertain and the sample size was too small. Based on the findings of this study, more high-quality clinical trials are needed to confirm the efficacy of combination treatment.

  • Objectives The purpose of this study was to figure out the effect and safety of electro-acupuncture and acupuncture on cold hypersensitivity on hands and feet(CHHF) by Sasang constitution. Methods 72 subjects were recruited from three Korean medical hospitals from October 2019 to October 2020. Subjects were randomly allocated in 1:1:1 ratio to electro-acupuncture group(EA group), acupuncture group(AC group), and control group. The EA and AC group received treatment twice a week for 5 weeks. We tried to confirm the effectiveness of electro-acupuncture and acupuncture treatment by checking changes in Visual analogue score(VAS), body temperature of LU4, PC8, ST32, LR3, and WHOQOL-BREF score. Results The VAS score of CHHF was reduced after treatment, and the effect continued for 4 weeks after the end of treatment in all Sasang constitution, all treatment groups. In all Sasang constitution, the body temperature of the electro-acupuncture group or acupuncture grouop was higher than that of the control group except LU4 in visit 11. And no clinically significant adverse events have been identified. Conclusions Electro-acupuncture and acupuncture treatment are effective on hypersensitivity on hands on feet, and the effect was shown regardless of Sasang constitution.

  • Background: Herpes zoster is a common dermatologic disorder. However, it rarely occurs in children and adolescents in Gwangju-Jeonnam province. Objective: This study aimed to analyze the epidemiological features and clinical characteristics of herpes zoster in children and adolescents. Methods: A retrospective survey was conducted on patients who visited the department of dermatology of Chosun University Hospital in Gwangju-Jeonnam province within the past 8 years. The medical records of 103 patients aged <18 years were reviewed. We analyzed for age, gender, accompanying symptoms, dermatomal distribution, underlying disease, treatment, and complications with serologic test. Results: The male-to-female ratio of the participants was 1.08:1, and their mean age was 13.0 years. Underlying diseases were observed in 3% (3/102) of the patients. The most common dermatomal distribution was thoracic dermatome (34%), followed by trigeminal (26%), cervical (20%), lumbar (15%), and non-skin (6%). The most common accompanying symptoms were headache (10%), fever (3%), and myalgia (3%). No difference was observed between patients who were varicella-zoster virus (VZV) IgM-positive and those who were VZV IgM-negative in terms of dermatome, visual analogue scale (VAS), severity, and body mass index (BMI). Conclusion: In children and adolescents with herpes zoster, the gender ratio and dermatomal distribution were similar to those previously reported, except for the low rate of underlying diseases. The incidence of herpes zoster in children was not significantly associated with immunosuppression and underlying diseases. Higher VZV IgM titer was not associated with dermatomal distribution, higher VAS score, or BMI. This study first compared the serological test results of children.
