Objectives : The purpose of this study was to examine the knowledge of people in general about orthodontic treatment and their attitude to that by conducting a survey in a bid to provide information on the improvement of their incorrect awareness of orthodontics and on the development of clinical orthodontic treatment. Methods and Results : The subjects in this study were 389 people in general who resided in Seoul and Gyeonggi Province. A self-administered survey was conducted, and the findings of the study were as follows: 1. As for awareness of orthodontic treatment among the people in general by gender, the women knew better about orthodontic treatment than the men, and the gender gap was significant(p<0.05). 2. Concerning satisfaction with the shape and arrangement of the teeth by age, those who were in their 20s were most satisfied, and the teens were satisfied the least. There were significant gaps according to age (p<0.05). 3. As a result of checking the degree of their inconvenience about the use of chewing teeth by age, the people who were in their 30s felt the most inconvenience, and the gap between them and the others was significant(p<0.01). 4. As a result of asking them whether they had an intention to receive orthodontic treatment, the women had a more intention to do that than the men(p<0.001). By age, the younger respondents had a more intention, and the gaps between them and the others were significant(p<0.001). 5. As a result of analyzing their perception of the positives of orthodontics by gender, the women took a more positive view of it than the men, and their gap was significant(p<0.01). Conclusions : When orthodontic treatment or orthodontic treatment counseling is provided to orthodontic treatment patients or people in general in the field of clinical dentistry, it should be noted that the way patients and people in general look at orthodontic treatment is different according to their age and gender, and they should be informed of the positives of orthodontic treatment to step up the development of orthodontic treatment.
Purpose: This study aims to identify the types of health-related quality of life (QoL) based on the EuroQoL 5 Dimensions among community older people and predict the factors affecting these types. Methods: This study used data from the 2016 Korea Health Panel Survey, whose participants included 3,848 older people. The data were analyzed using the software jamovi 1.2.17 and Mplus 8.2 for latent class analysis. Results: The subgroups of the older people's health-related QoL were identified as three latent classes: General stable type (43.9%), pain-related low type (35.0%), and general low type (21.1%). The types and characteristics of health-related QoL among the latent classes differed. Comparing the difference between the general low type and general stable type, the subjects showed higher probability of belonging to the general stable type when they were men, younger, higher education level, employment, better subjective health, lower BMI and stress level, and no suicidal ideation. A comparison between the general low type and the pain-related low type showed that the subjects were more likely to be classified as the pain-related low type when they were younger, higher education, employment, and better subjective health. Conclusion: The results showed a significant heterogeneity in the types of health-related QoL among community older people, and the predictors for each type were not the same. These findings present basic data for cultivating nursing interventions that enhance health-related QoL.

Purpose: This study investigated self-food restriction during breastfeeding, reviewed the literature showing the effect of maternal diet on the health of breast-fed infants, and explored the validity of dietary restrictions. Methods: Questionnaire data were collected from breastfeeding Korean mothers who visited the pediatric clinic of Cheil General Hospital & Women's Healthcare Center from July 2015 through August 2015. The survey included items assessing maternal age, number of children, maternal educational attainment, household income, degree of difficulty with self-food restriction, types of self-restricted foods, dietary customs during breastfeeding, and sources of information about breastfeeding. Results: The questionnaire was completed by 145 mothers. More than a third (n=56, 39%) had discomfort from and usually avoided 4-5 types of food (mean, 4.92). Mothers younger than 40 years had more discomfort (odds ratio [OR], 12.762; P=0.017). Primiparas felt less discomfort than multiparas (OR, 0.436; P=0.036). Dietary practices were not influenced by maternal educational attainment or household income. The most common self-restricted foods were caffeine (n=131, 90.3%), spicy foods (n=124, 85.5%), raw foods (n=109, 75.2%), cold foods (n=100, 69%), and sikhye (traditional sweet Korean rice beverage) (n=100, 69%). Most mothers (n=122, 84.1%) avoided foods for vague reasons. Conclusion: Most mothers restricted certain foods unnecessarily. Literature review identified no foods that mothers should absolutely avoid during breastfeeding unless the infant reacts negatively to the food.

Background and Aims: To explore the molecular mechanisms of miR-886-5p in breast cancer., we examined roles in inhibiting growth and migration of MCF-7 cells. Methods: MiR-886-5p mimics and inhibitors were used to express or inhibit MiR-886-5p, respectively, and MTT and clone formation assays were used to determine the survival and proliferation. Hoechst 33342/ PI double staining was applied to detect apoptosis. The expression of caspase-3, caspase-8, caspase-9, MT1-MMP, VEGF-C and VEGF-D was detected by Western blotting, and the levels of MMP2 and MMP9 secreted from MCF-7 cells were assessed by ELISA. MCF-7 cell migration was determined by wound healing and Transwell assays. Results: We found that the growth of MCF-7 cells was inhibited upon decreasing miR-886-5p levels. Inhibiting miR-866-5p also significantly induced apoptosis and decreased the migratory capacity of these cells. The expression of VEGF-C, VEGF-D, MT1-MMP, MMP2, and MMP9 was also found to be decreased as compared to controls. Conclusions: Our data show that downregulation of miR-886-5p expression in MCF-7 cells could significantly inhibit cell growth and migration. This might imply that inhibiting miR-886-5p could be a therapeutic strategy in breast cancer.
It is reported that the expression level of MLL3 in gastric cancer tissue highly correlates with tumor progression. However, whether MLL3 genetic variants are associated with the risk of gastric cancer remains unclear. In this study, we conducted a genotyping analysis for MLL3 in 314 cases of gastric cancer and 322 controls from the Chinese Han population. 4 SNPs (rs6943984, rs4725443, rs3800836, rs6464211) were selected for the present analysis. We found 2 SNPs (rs6943984, rs4725443) of MLL3 gene were significantly associated with the risk of gastric cancer : the rs6943984 with the minor allele A and rs4725443 with the minor allele C revealed strong associations with increased gastric cancer risk [P < 0.001, OR=1.97, 95% CI=1.48~2.64 and P <0.001, OR=2.23, 95% CI=1.54~3.24]. Haplotype analysis of the four SNPs showed that haplotype A-T-A-C, G-T-G-C, and G-C-A-C increased the risk of gastric cancer (P <0.001, P=0.18, and P<0.001, respectively), while haplotype G-T-A-C significantly reduced the risk of gastric cancer (P <0.001). We concluded that MLL3 variants are significantly associated with gastric cancer risk. Our results for the first time provided new insight into susceptibility factors of MLL3 gene variants in carcinogenesis of gastric cancer of the Chinese Han population.
Background: To investigate the clinical efficacy of expanded activated autologous lymphocytes (EAAL) in patients with small cell lung cancer (SCLC). Materials and Methods: A total of 32 SCLC patients were selected and randomly divided into EAAL treatment and control groups, 16 cases in each. EAAL were obtained by proliferation of peripheral blood mononuclear cells (PBMCs) of patients followed by phenotype determination. Clinical data of all patients were recorded. Patients of both groups were followed up and the overall survival (OS) were compared retrospectively. Results: After culture and proliferation in vitro, the percentages of $CD3^+$, $CD3^+CD8^+$, $CD45RO^+$, $CD28^+$, $CD29^+$, $CD8^+CD28^+$ and $CD3^+CD16^+/CD56^+$ cells increased markedly (p<0.05). The OS of the EAAL treatment group was longer than that of control group, but the difference was not statistically significant (p=0.060, HR=0.487, 95%CI 0.228~1.037). 1- to 3-year survival rates in EAAL treatment group were longer than those in control group, but there was still no significant difference (p>0.05). COX multivariate regression analysis showed that the number of chemotherapy cycles and the application of EAAL immunotherapy were independent prognostic factors for SCLC patients. The OS in females and chemotherapy${\leq}6$ cycles were obviously prolonged after EAAL immunotherapy. Conclusions: In vitro induction and proliferation of EAAL is easy and biologically safe. Generally, EAAL adoptive immunotherapy can evidently prolong the OS of SCLC patients.

Objective: This study was performed to evaluate testicular sperm chromatin condensation using aniline blue-eosin (AB-E) staining and its effects on IVF-ET. Methods: Chromatin condensation was analyzed using AB-E staining in 27 cases of testicular sperm extraction. There were 19 cases of obstructive azoospermia (OA) and 8 cases of non-obstructive azoospermia (NOA) in IVF-ET. Mature sperm heads were stained red-pink whereas immature sperm heads were stained dark blue. The percentage of sperm chromatin condensation was calculated from the ratio of the number of red-pink sperm to the total number of sperm analyzed. Results: The overall percentages of chromatin condensation in OA and NOA were $31.1{\pm}11.2%$ and $26.3{\pm}14.4%$, respectively. The fertilization rate was significant higher in OA than NOA ($p$ <0.05); however, the rates of good embryos and clinical pregnancy did not show statistical differences. In OA and NOA, statistical differences were not observed in the rate of chromatin condensation, fertilization, good embryos, and clinical pregnancy between the pregnant group and non-pregnant group. Conclusion: Chromatin condensation is less stable than OA and showed a low fertilization rate in NOA. While there were no significant differences in chromatin condensation results between NOA and OA, we propose that a pattern of decreased chromatin condensation in NOA is one of the factors of low fertilization results requiring further study.
Characterized by abnormal proliferation and migration of vascular smooth muscle cells (VSMCs), neointima hyperplasia is a hallmark of vascular restenosis after percutaneous vascular interventions. Vaccinia-related kinase 1 (VRK1) is a stress adaption-associated ser/thr protein kinase that can induce the proliferation of various types of cells. However, the role of VRK1 in the proliferation and migration of VSMCs and neointima hyperplasia after vascular injury remains unknown. We observed increased expression of VRK1 in VSMCs subjected to platelet-derived growth factor (PDGF)-BB by western blotting. Silencing VRK1 by shVrk1 reduced the number of Ki-67-positive VSMCs and attenuated the migration of VSMCs. Mechanistically, we found that relative expression levels of β-catenin and effectors of mTOR complex 1 (mTORC1) such as phospho (p)-mammalian target of rapamycin (mTOR), p-S6, and p-4EBP1 were decreased after silencing VRK1. Restoration of β-catenin expression by SKL2001 and re-activation of mTORC1 by Tuberous sclerosis 1 siRNA (siTsc1) both abolished shVrk1-mediated inhibitory effect on VSMC proliferation and migration. siTsc1 also rescued the reduced expression of β-catenin caused by VRK1 inhibition. Furthermore, mTORC1 re-activation failed to recover the attenuated proliferation and migration of VSMC resulting from shVrk1 after silencing β-catenin. We also found that the vascular expression of VRK1 was increased after injury. VRK1 inactivation in vivo inhibited vascular injury-induced neointima hyperplasia in a β-catenin-dependent manner. These results demonstrate that inhibition of VRK1 can suppress the proliferation and migration of VSMC and neointima hyperplasia after vascular injury via mTORC1/β-catenin pathway.

This study aimed to compare the perception of dental role-play or dental ASMR videos between the general public and dental personnel, to determine whether they are suitable for mass media or educational media, and to identify guidelines for video production. The survey consent form was agreed on using SNS for the general public and dental personnel, 236 ordinary people and 232 dental officers who said that they watched dental ASMR videos were analyzed. The questionnaire consisted of 27 questions for the general public and 31 for dental personnel. Data were analyzed using the chi-square test and the Independent T-test using SPSS 25.0 ver. The viewing experience of 'dental ASMR videos' was significantly higher among dentists (84.7%) than among the general population (71.5%) (p<0.001). Overall, 53.8% of the general public were interested in watching dental ASMR videos, and 47.8% of dental personnel acquired clinical information from them.. Overall, 64.8% of the general public and 65.5% of the dental workforce felt that such technical videos should be produced under the guidance of experts in the field to provide accurate technical information. It is necessary to avoid indiscriminate video production with inaccurate information produced by non-experts and to continuously monitor dental ASMR videos dental institutions for better quality of the videos.
Objective: To assess the effects of perioperative comprehensive supportive care interventions on outcome of Chinese esophageal cancer patients in a prospective study. Methods: 60 patients with primary esophageal carcinoma were randomized into an intervention group (IG, n=31) and a control group (CG, n=29). The Chinese version of symptom checklist-90 (SCL-90) was adopted to assess their psychological status. The interventions, including health education, psychological support, stress management, coping strategies and behavior training, were carried out in 3 phases (preoperative, postoperative I and postoperative II), and psychological effects were thereafter evaluated accordingly before surgery, and 1 week, 4 weeks and 24 weeks post-surgery. Medical costs were estimated at discharge. Survival of patients was estimated each year post-surgery. General health status and satisfaction-with-hospital were surveyed by a follow-up questionnaire 4 years post-surgery. Results: All the subjects demonstrated higher scores in the preoperative phase than the normal range of Chinese population concerning 7 psychological domains including somatization, obsessive-compulsive, depression, anxiety, hostility, phobic anxiety and paranoid ideation. Although no significant difference was observed between the two groups at admission, the scores of IG, which tended to decrease at a faster rate, were generally lower than those of CG at weeks 1, 4 and 24 post-surgery. The length of hospital stay and medical costs of IG were significantly less than those of CG and satisfaction-with-hospital was better. However, there was no significant difference in 4-year survival or health status between two groups. Conclusions: Appropriate perioperative comprehensive supportive care interventions help to improve the psychological state of Chinese patients with esophageal carcinoma, to reduce health care costs and to promote satisfaction of patients and their families with hospital.
