Abstract: BACKGROUND: Research on the genetic mechanisms of hypertension has been a hot topic in the cardiovascular field. OBJECTIVE: To study the correlation between senile hypertension and traditional Chinese medicine (TCM) constitution and lipoprotein lipase (LPL) gene polymorphism and to provide the theoretical basis for TCM prevention and treatment of hypertension. METHODS: The elderly population in communities in Shanghai (hypertensive: 264 cases; non-hypertensive: 159 cases) was taken as the research object. Essential data and information on TCM constitution were collected. The LPL gene mutation was detected using the second-generation sequencing method. Statistical analysis was …performed to clarify the relationship between hypertension and senile hypertension. The correlation of TCM constitution with risk factors and LPL gene polymorphisms was studied. RESULTS: The primary TCM constitutions in the hypertension group were phlegm-dampness constitution (51.52%), yin-deficiency constitution (17.42%), balanced constitution (15.53%), and yin-deficiency (9.43%). Logistic regression analysis showed that the phlegm-dampness constitution (P < 0.05, OR = 2.587) and yin-deficiency constitution (P < 0.01, OR = 2.693) were the risk constitutions of hypertension in the elderly. A total of 37 LPL gene mutation loci (SNP: 22; new discovery: 15) were detected in the LPL gene, and the mutation rates of rs254, rs255, rs3208305, rs316, rs11570891, rs328, rs11570893, and rs13702 were relatively high, which were 26.24%, 26.24%, 16.08%, 14.66%, 13.24%, 12.06%, and 10.64%. In the phlegm-dampness group, the proportion of rs254 CC type, rs255 TT type, and rs13702 TT type in the hypertensive group (77.21%, 77.21%, and 93.38%) was higher than that in the non-hypertensive group (56.41%, 56.41%, and 82.05%), The difference was statistically significant (P < 0.05). CONCLUSION: The phlegm-dampness constitution and yin-deficiency constitution are the risk factors of hypertension in the elderly; in the phlegm-dampness population, rs254 CC type, rs255 TT type, and rs13702 TT type are the risk factors for elderly hypertension.

Abstract: BACKGROUND: Polyetheretherketone (PEEK) is a polyaromatic semi-crystalline thermoplastic polymer with mechanical and lubrication properties favorable for biomedical applications. Despite of its aesthetic appearance, ceramic brackets are unsatisfactory in brittleness and thickness, while PEEK is a potential material for aesthetic orthodontic brackets. OBJECTIVE: To fabricate a novel aesthetic orthodontic bracket and evaluate friction properties of PEEK and stainless steel wires. METHODS: All polyether ether ketone (PEEK) and ceramic samples disks were made into disks (diameter, 5 mm; thickness, 2 mm). The tested surfaces of PEEK were ground with #600, #800 and #1200 SiC papers, followed …by polishing with Sof-Lex kit (3M ESPE, USA). The surface roughness was tested using a laser profilometer device (VK-X200, Keyence, Japan). The COFs of the specimens and stainless steel (SS) archwires were tested using a Universal Micro-Tribotester (UMT-3, Bruker, USA). The wear scratches on the materials’ surfaces were examined by using a scanning electron microscope (SEM) (Hitachi SU8010). The elastic modulus and hardness of samples were examined with a nano-indenter (XP, Keysight Technologies, USA). RESULTS: The mean surface roughness of PEEK and Ceramic are 0.320 ± 0.028 μ m and 0.343 ± 0.044 μ m, respectively. PEEK has a lower Friction coefficient than Ceramic and the difference between the two groups was statistically significant (P < 0.05). The abrasive wear of Ceramic was the main wear style and was characterized by the observation of chipping fractures, while PEEK surface looked smooth without obvious scale-like desquamations and granular debris, indicating adhesive wear. CONCLUSION: Within the limitations of the present study, PEEK shows lower coefficient of friction than ceramic. PEEK has excellent properties such as low friction coefficient, smooth surface and good mechanical properties, and thus meets the requirements for orthodontic brackets. It is considered as a potential bracket material with both low friction and aesthetic performance. Show more

Abstract: BACKGROUND: Traditionally, alcohol sprays are used for disinfection of acrylic-base denture surfaces. A limited number of studies have assessed the role of antimicrobial photodynamic therapy (aPDT) in this regard; however, it remains debatable whether conventional alcohol sprays are superior to aPDT in terms of antifungal activity or vis versa. OBJECTIVE: The aim of the present in vitro study is to compare the antifungal activity of conventional alcohol sprays and aPDT on acrylic denture resin. METHODS: Individuals wearing complete dentures at least on one arch were included. Dentures were randomly divided into three …groups. Groups 1-3 were disinfected with an alcohol-based antiseptic spray and aPDT, respectively. Assessment of oral yeast growth was done using swab samples. The culture mediums were incubated at 37 ∘ C for 72 hours and viewed through a microscope. The numbers of colony forming units (CFU/ml) were determined. P < 0.05 were considered statistically significant. RESULTS: At baseline, the mean CFU/ml in Groups 1–3 were comparable. After disinfection, a statistically significant reduction in microbial CFU/ml was observed in Groups 1 (P < 0.05) and 2 (P < 0.05) compared with baseline. In Group 3, there was no difference in CFU/ml throughout the study. After disinfection, there was no difference in microbial CFU/ml in dentures in Groups 1 and 2. CONCLUSION: Conventional alcohol sprays are as effective as aPDT towards reducing oral yeasts CFU/ml on acrylic denture resin. Show more

Abstract: BACKGROUND: Undesirable effects of tooth bleaching can alter the biomechanical properties of enamel. OBJECTIVE: To determine the influence of strontium fluorophosphate bioactive glass (Sr-FPG) on color, microhardness and surface roughness of enamel bleached with 35% hydrogen peroxide. METHODS: The labial enamel of 36 extracted intact human anterior teeth were divided into 3 groups (n = 12), group 1 (HP): bleaching with 35% hydrogen peroxide only, group 2 (Sr-HP): bleaching with Sr-FPG incorporated 35% hydrogen peroxide and group 3 (HP-SrFPG): bleaching with 35% hydrogen peroxide followed by remineralization with …Sr-FPG. Four consecutive eight-minute applications of the bleaching gel were done twice in all the groups. Color change (Δ E), microhardness and surface roughness were evaluated at baseline, post-bleaching and post-remineralization using spectrophotometer, Vickers hardness tester and profilometric analysis respectively. RESULTS: The mean Δ E among the groups was statistically similar (p > 0.05). Bleaching with HP significantly reduced microhardness (p < 0.05), whereas bleaching with Sr-HP and HP-SrFPG did not (p > 0.05). Post-bleaching microhardness in Sr-HP was significantly higher than HP-SrFPG (p < 0.05). An increased surface roughness was seen in Sr-HP bleached samples (p < 0.05). CONCLUSION: The addition of Sr-FPG to hydrogen peroxide significantly improved enamel microhardness than its use post-bleaching. An increase in surface roughness was seen post-bleaching with HP and Sr-HP. Show more

Abstract: BACKGROUND: Lung cancer is prone to metastasize to the brain, which is difficult for surgery and leads to poor prognosis due to poor chemotherapy efficacy. OBJECTIVE: Our aim is to evaluate the efficacy and safety of stereotactic body radiotherapy (SBRT) for brain multi-metastases. METHODS: In the retrospective study, a total of 51 non-small cell lung cancer (NSCLC) patients with brain multi-metastases (3–5 metastases) receiving SBRT in the local hospital between 2016 and 2019 were enrolled for analyzing the efficacy and safety of SBRT. The primary endpoints included 1-year local control rate, radiotherapy toxicity, …overall survival and progression-free survival. RESULTS: The median follow-up for the enrolled patients was 21 months, and the 1-year and 2-year OS rates were 82.4% and 45.1%, respectively. Demographic analysis showed no significant differences between SBRT alone and combination with whole brain radiotherapy in clinical characteristics including age, gender and Eastern Cooperative Oncology Group performance status. The 1-year local control rate was 77.3% (17/22) for SBRT alone, which was comparable to 79.3% (23/29) of combined radiotherapy. Cox proportional hazard regression demonstrated that the prognostic benefit of combining WBRT was not significantly superior to SBRT alone (HR = 0.851, P = 0.263). Their radiotherapy toxicity rate was lower in SBRT alone group (13.6%, vs. 44.8% for combination; P = 0.017). CONCLUSION: The current research suggested that SBRT alone could effectively relieve tumor burden and improve the prognosis and quality of life for NSCLC patients with brain multi-metastases, which should be validated in further prospective clinical trials.

Abstract: BACKGROUND: In view of the lack of attention and predictability in postpartum breastfeeding in primiparas, health education on breastfeeding during pregnancy should be carried out to publicize the benefits of breastfeeding. OBJECTIVE: To investigate how well the primiparas during pregnancy are known of breastfeeding knowledge, and to provide a basis for developing health education measures for them. METHODS: With the adoption of the objective sampling method and the principle of saturation, 10 primiparas in the obstetrics outpatient department of the Hunan Provincial People’s Hospital were selected as the study participants. Semi-structured in-depth interviews …combined with the observation method were used for data collection. The interview data were analyzed and the theme was refined by Colaizzi’s seven-step method. RESULTS: The results of the four themes of the cognition of breastfeeding knowledge among primiparas were as follows: Lack of knowledge and curiosity about breastfeeding in some women, lack of access to correct breastfeeding knowledge, insufficient support from family members for postpartum breastfeeding, and lack of approach to solve problems during breastfeeding among primiparas. CONCLUSION: Due to the current problems of the cognition of breastfeeding knowledge in primiparas, it was imperative to build a health education model suitable for primiparas to improve this knowledge.

Abstract: BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a common chronic respiratory disease worsening airflow limitation. OBJECTIVE: To explore pulmonary function rehabilitation, life quality and prognosis in patients with severe COPD. METHODS: Between February 2018 and August 2021, 150 patients with severe COPD cured in our hospital were arbitrarily assigned into the control group (n = 75) and study group (n = 75). The control group received routine treatment and the research group received multidisciplinary diagnosis and treatment. The body mass index, airflow obstruction, …dyspnea and exercise (BODE), pulmonary function, the number of acute attacks, 6-minute walking distance (6MWD), Borg score and life quality were compared. RESULTS: There was no remarkable difference in BODE score before treatment (P > 0.05). During the 2- and 6-month following treatment, the BODE score of the study group was lower (P < 0.05). In the study group, FEV1 percentage of the predicted value, forced expiratory volume in one second (PPO-FEV1) and the percentage of forced expiratory volume in one second/forced vital capacity (FEV1/FVC) in the first second were higher (P < 0.05). In the study group, there were fewer acute attacks (P < 0.05). After treatment, the 6MWD of the study group following 2- and 6-month treatment was higher (P < 0.05). The Borg scores of the study group at 2- and 6-months after treatment were lower (P < 0.05). There were no remarkable differences in the score of life quality before treatment (P > 0.05), however, the symptom score, activity score, influence score and total score of the study group were lower after the treatment (P < 0.05). CONCLUSION: The application of multidisciplinary diagnosis and treatment model can promote the rehabilitation of pulmonary function of patients with severe COPD, improve their prognosis, slow down the development of the disease and enhance their life quality.

Abstract: BACKGROUND: Amblyopia is a neurological deficit in binocular vision that affects 3% of the population and is the result of disruptions in early visual development. OBJECTIVE: In this study, we used a visual perceptual learning system for the short-term treatment of children with ametropic amblyopia and evaluated the clinical efficacy of this system in terms of visual plasticity. METHODS: We conducted a retrospective analysis of the clinical data of 114 children (228 eyes) with refractive amblyopia, who were aged 6.51 ± 1.51 years. Prior to the treatment, we evaluated all …children with amblyopia using the visual information processing test. We determined the type of amblyopic defect according to the type of amblyopia, corrected visual acuity, and advanced visual function test results. Based on the type of defect, each child with amblyopia was given short-term visual perception training for 10 days. Finally, we compared the results of visual acuity and visual information processing tests before and after the treatment. RESULTS: The best-corrected visual acuity of patients was better after 10 days of visual training than that before training (P < 0.05). The perceptual eye position after training improved with statistically significant differences in horizontal and vertical perceptual eye position (both P < 0.05) compared to that before training. The number of amblyopic children without suppression in both eyes was 81 cases (71.1%) after training which was higher than that (65 cases, or 57.0%) before training, with a statistically significant difference (P < 0.05). Binocular fine stereopsis and dynamic stereopsis improved after training with a statistically significant difference (both P < 0.05). CONCLUSION: In this study, it was found that patients with amblyopia showed visual plasticity. Moreover, continuous visual perceptual learning improved the best-corrected visual acuity and recovered stereopsis in children with refractive amblyopia. Show more

Abstract: BACKGROUND: After stroke, gait training is a key component of rehabilitation, and most individuals use a variety of walking aids depending on their physical condition and environment. OBJECTIVE: This study aimed to investigate the potential effect of a one-arm motorized gait device for gait assist of chronic hemiplegic stroke survivors through comparison with traditional gait devices (parallel bar and hemi-walker). METHODS: This study was conducted on 14 chronic hemiplegic stroke survivors. The participants were asked to walk under three conditions using different gait devices, and their gait parameters during walking were collected and …analyzed. The first condition involved walking on parallel bars; second condition, walking using hemi-walkers; and third condition, walking using one-arm motorized gait devices. With the use of a gait analysis system, the spatio-temporal gait parameters in each condition were collected, such as gait velocity, cadence, step length, stride length, single support time, and double support time. RESULTS: In the results by repeated-measures ANOVA or the Friedman test, a significant difference was found in the gait parameters among all three conditions (p < 0.05). The post-hoc test showed a significant change in the spatio-temporal gait parameters (especially, velocity, cadence and affected side single and double support time) when one-arm motorized gait device were used compared with parallel bars and hemi-walkers (p < 0.05). CONCLUSION: The results of this study suggest that one-arm motorized gait devices developed for hemiplegic stroke survivors may be more effective potentially than parallel bars and hemi-walkers in gait assistance of chronic hemiplegic stroke survivors.
