ABSTRACT

: To evaluate the application of medical magnifying loupes in diagnosis of oral mucosal diseases. Twenty-four patients with plaque-type oral lichen planus or homogeneous oral leukoplakia were inspected by naked eyes or assistance with magnifying loupes. Histopathological results were used as the gold standard to evaluate the sensitivity, specificity and accuracy of the two methods in clinical diagnosis. Questionnaires were used to evaluate the subjective effect of magnifying loupes on the diagnosis efficiency of oral mucosal diseases and to explore the most suitable parameters for application. The sensitivity, specificity and accuracy of medical magnifying loupes for the identification of plaque-type oral lichen planus and homogeneous oral leukoplakia were 94.74%, 100.00% and 95.83%, respectively, which were significantly higher than those of naked eye inspection (89.47%, 80.00% and 87.50%). The effective rate of magnifying loupes assisted diagnosis was 91.76% according to physicians' subjective evaluation. The most suitable parameters were 3.5 times magnification and working distance. The medical magnifying loupes can effectively improve the efficiency of the inspection and diagnosis of oral mucosal diseases, and have the characteristics of convenience and real-time. The recommended clinical parameters are 3.5 times magnification and working distance.

ABSTRACT

Efforts to control inflammation and achieve better tissue repair in the treatment of periodontitis have been ongoing for years. Human β-defensin 3, a broad-spectrum antimicrobial peptide has been proven to have a variety of biological functions in periodontitis; however, relatively few reports have addressed the effects of human periodontal ligament cells (hPDLCs) on osteogenic differentiation. In this study, we evaluated the osteogenic effects of hPDLCs with an adenoviral vector encoding human β-defensin 3 in an inflammatory microenvironment. Then human β-defensin 3 gene-modified rat periodontal ligament cells were transplanted into rats with experimental periodontitis to observe their effects on periodontal bone repair. We found that the human β-defensin 3 gene-modified hPDLCs presented with high levels of osteogenesis-related gene expression and calcium deposition. Furthermore, the p38 MAPK pathway was activated in this process. In vivo, human β-defensin 3 gene-transfected rat PDLCs promoted bone repair in SD rats with periodontitis, and the p38 mitogen-activated protein kinase (MAPK) pathway might also have been involved. These findings demonstrate that human β-defensin 3 accelerates osteogenesis and that human β-defensin 3 gene modification may offer a potential approach to promote bone repair in patients with periodontitis.

ABSTRACT

BACKGROUND: MiRNAs have been shown to be closely related to obesity and diabetes, which can be potential biomarkers for the diagnosis and prognosis of diabetes. OBJECTIVE: To review the roles of miRNAs in promoting insulin sensitivity, controlling insulin synthesis and regulating insulin resistance in hypoxic exercise, and to explore the mechanism of hypoxic exercise-mediated miRNAs in regulating glucose metabolism. METHODS: Relevant studies on hypoxic exercise glucose metabolism and miRNAs in PubMed, CNKI, WanFang databases were searched. The keywords were “miRNAs, low oxygen movement, hypoxic exercise, hypoxia-mediated, sugar metabolism, glucose metabolism” in English and Chinese, respectively. Relevant literatures published from 2007 to 2019 were searched and screened according to inclusion and exclusion criteria. RESULTS AND CONCLUSION: MiRNAs have the potential to regulate the expression of major protein cascades in the insulin signaling pathway by regulating the expression of target genes and thereby affecting the homeostasis of glucose metabolism. miRNAs can also be used as single molecules or in combination therapy. There is an urgent need to integrate miRNAs into insulin signaling pathways and develop new miRNAs-related diagnostic and therapeutic approaches in hopes of addressing type 2 diabetes in the future. Studying the mechanism of the effects of miRNAs on glucose metabolism in hypoxic exercise can not only provide a theoretical basis for scientific hypoglycemic and body mass control, but also can be used as an intervention for the prevention and control of diseases related to glucose metabolism disorders. Diseases caused by abnormal glucose metabolism provide new therapeutic approaches.

ABSTRACT

BACKGROUND: MicroRNAs (miRNAs) have emerged as the critical modulators of the tumorigenesis and tumor progression. METHODS: The levels of miR-663 in ovarian cancer cell lines and clinical tissues were detected using qRT-PCR assays. The Transwell invasion and wound healing assay were conducted to assess the roles of miR-663 in the migration and invasion of ovarian cancer cell in vitro. Rescue assays were carried out to confirm the contribution of tumor suppressor candidate 2 (TUSC2) in the aggressiveness of cancer cell which was regulated by miR-663. RESULTS: The levels of miR-663 were up-regulated in ovarian cancer tissues in comparison with the corresponding normal tissues. Up-regulation of miR-663 increased the proliferation, colony formation, migration and invasion of ovarian cancer SKOV3 cell. Additional, over-expression of miR-663 increased the tumor growth of SKOV3 in xenograft model. Bioinformatics analysis and luciferase reporter assay identified that miR-663 decreased the level of TUSC2 via binding to the 3'-UTR of TUSC2 gene. Finally, the expression of TUSC2 was inversely associated with the level of miR-663 in ovarian carcinoma tissue and over-expression of TUSC2 inhibited the migration and invasion abilities of SKOV3 that was promoted by miR-663. CONCLUSION: Altogether, these results indicate that miR-663 acts as a potential tumor-promoting miRNA through targeting TUSC2 in ovarian cancer.

ABSTRACT

BACKGROUND: A large number of cytokines produce in the periodontium on the tension side during orthodontic tooth movement, participate in periodontal remodeling, and make the tooth move to its normal position, thus achieving alveolar remodeling. Heat shock protein 27 (HSP27) is reported to be involved in the periodontal remodeling. OBJECTIVE: To investigate the expression of HSP27 in the rat periodontium on the tension side during the orthodontic tooth movement.METHODS: The rat models of orthodontic tooth movement were constructed using NiTi coil spring with the force value of 50 g. The periodontal samples were collected at 1, 3, 5, 7, 10 and 14 days after exerting force to detect the expression level of HSP27 in the periodontium on the tension side.RESULTS AND CONCLUSION: Immunofluorescence staining results revealed that the expression level of HSP27 in the periodontal tissues began to increase at the 1st day after exerting force, reached the highest level at the 3rd day, and then fell to the initial level at the 5th day. To conclude, HSP27 is evoked by orthodontic force early, and it may play a role in periodontal remodeling.

ABSTRACT

Objective To discuss the effects of acupuncture therapy on resting state functional magnetic resonance imaging (fMRI) in patients with ischemic stroke; To explore the central mechanism of acupuncture therapy.Methods Ten is chemic stroke patients with hemiplegia limbs and ten matched control subjects were included. Treatment group was given anti-platelet aggregation, anticoagulation, and nutrition brain cell therapy. At the same time, acupuncture therapy was given, taking Jianyu, Quchi, Shousanli, Waiguan, Hegu, Zusanli, Fenglong, Yanglingquan, Sanyinjiao, and Taichong, with even reinforcing-reducing method, and retaining the needle 30 min, manipulating needle every 10 min, once a day, 5 times a week, needle stopping for 2 d, for continuous 30 d. The health group did not undergo any treatment. BOLD-fMRI imaging technique was used, and based on RSET1.8 software, the parameters of brain activity before and after treatment were observed by amplitude of low frequency fluctuation (ALFF) method. The Results were compared with healthy group. Results Before treatment, the ALFF value of left caudate nucleus, putamen and globus pallidus in the treatment group was lower than that in the health group, and the ALFF value of bilateral precentral and postcentral gyrus, left grus frontalis superior, gyrus frontalis medius, gyrus temporalis medius and precuneus was higher than the health group (P<0.05). After treatment, the ALFF value in left caudate nucleus, putamen and globus pallidus in the treatment group was higher than that before treatment, and the ALFF value in left gyrus frontalis superior, gyrus frontalis medius and precuneus decreased than before group (P<0.05).Conclusion In the resting state of the ischemic stroke patients with hemiplegia limbs, the principal injured brain regions are caudate nucleus, putamen and globus pallidus. Acupuncture has a regulatory role for these brain areas, presumably may be the central mechanism of efficacy.

ABSTRACT

Objective The abnormal ankle-brachial index ( ABI) is associated with the incidence of cardiocerebral vascular diseases, but little is known about its relationship with cerebral microbleeds (CMB).This study aimed to investigate the correlation be-tween ABI≤0.9 and different distribution patterns of CMB . Methods We enrolled 187 patients with acute lacunar infarction , inclu-ding 115 non-CMB cases and 72 CMB cases (20 strictly lobar, 24 strictly deep, and 28 lobar and deep).We analyzed the differences between the two groups and the association of abnormal ABI with the occurrence and distribution of CMB by logistic regression analysis . Results ABI≤0.9 was found in 57 (30.5%) of the patients, with a significantly higher incidence rate in the CMB group than in the non-CMB group (43.1%vs 22.6%, P=0.003).The level of ABI was negatively correlated with the number of CMBs (r=-0.211, P=0.006).Multivariate logistic regression analysis after adjusted for confounders indicated that ABI ≤0.9 was significantly associated with the presence of CMB (OR=2.363;95%CI:1.181-4.729), deep CMB (OR=3.434;95%CI:1.283-9.187), and lobar and deep CMB ( OR=2.837;95%CI:1.098-7.333) in patients with ischemic cerebrovascular disease . Conclusion Decreased ABI is a risk factor of CMB, particularly deep CMB, in patients with ischemic stroke.

ABSTRACT

Objective To investigate the clinical characteristics of posterior malleolar ankle fracture, and the selection of the surgical approach. Methods From January 2013 to September 2015, 83 cases of posterior malleolar fractures were retrospectively analyzed. Haraguchi typing was performed based on the three-dimensional CT. There were 54 cases with HaraguchiⅠtype, 16 cases with HaraguchiⅡtype, and 13 cases with HaraguchiⅢtype. The patients who were HaraguchiⅠand Haraguchi Ⅲtypes accepted the operation with posterolateral approach. The patients who were HaraguchiⅡtype and combined medial malleolus fracture accepted the operation with medial approach. The HaraguchiⅡpatients who were not combined medial malleolus fracture were used the medial paraachilles approach. Images of the ankle joint were filmed 2 weeks, 4 weeks, 12 weeks, 6 months and 12 months after the surgery. The healing time, complications and corresponding record outcome were determined by X-ray and clinical examination. At the last follow-up, ankle function and quality of life of patients were evaluated according to the American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hindfoot score and SF-36. Results Eighty-three patients were follow-up for 6-24 (mean 15.4± 6.2) months. The fractures healed on X-ray. The average X-ray healing time was from 12 to 24 (mean 18.6±4.2) weeks. AOFAS score was 71 to 100 (mean 88.4±8.4) points. Sixty-seven cases were excellent, 14 cases were good, 2 cases were moderate, and good rate was 97.59%. SF-36 physiological score was 31.6-69.2 points(mean 48.4 ± 4.8 points);SF-36 psychological score 28.6-64.5 points(mean 45.8 ± 3.5 points). Chronic ankle pain was complained by one patient. He was diagnosed traumatic arthritis, oral non-steroidal drugs was used to relief his ankle pain. One patient wound infected, and healed after treatment. No instrument failure and fracture displacement were found. Conclusion According to fracture morphology and clinical features after posterior malleolar ankle fracture, different surgical approaches are selected, which will be satisfied with the outcome.
