Objective: To explore the effectiveness of various interventions in accelerating tooth movement, a systematic review and net-work meta analysis were used to draw a conclusion. Methods: MEDLINE, EMBASE, Willey Library, EBSCO, Web of Science Databases, and Cochrane Central Register of Controlled Trials databases to identify relevant studies. ADDIS 1.16.6 and Stata 16.0 software were used for NMA. Results: Five thousand five hundred and forty-two articles were searched out. After screening by two independent investigators, forty-seven randomized controlled trials, 1 390 participants, were included in this network meta-analysis. A total of 11 interventions involving Piezocision (Piezo), Photobiomodulation therapy (PBMT), Plate- let-rich plasma(PRP), Electromagnetic field(EF), Low intensity laser therapy(LLLT), Low intensity pulsed ultrasound(LI-PUS), Low-frequency vibrations(LFV), Distraction osteogenesis(DAD), Corticotomy(Corti), Microosteoperforations (MOPS), Traditional orthodontic(OT)were identified and classified into 3 classes including surgical treatment, non-surgical treatment and traditional orthodontic treatment. According to SUCRA probability ranking of the best intervention effect, when orthodontic treatment lasted for 1 month, PBMT (90.6%), Piezo(87.4%) and MOPs(73.6%)were the top three interventions to improve the efficiency of canine tooth movement. When orthodontic treatment lasted for 2 months, Corti (75.7%), Piezo (69.6%) and LFV(58.9%)were the top three interventions for improving the mobility efficiency of canine tooth movement. When orthodontic treatment lasted for 3 months, Cort (73.3%), LLLT(68.4%)and LFV(60.8%)were the top three interventions for improving the mobility efficiency of canine tooth movement. Conclusion: PBMT and Piezo can improve the efficiency of canine tooth movement significantly after 1 month, while Corti and LFV can improve the efficiency of canine tooth movement better after 2 and 3 months.

Objective: To investigate the effect of puerarin on inflammation and alveolar bone resorption in rats with experimental periodontitis. Methods: Thirty-six 7 -week-old Sprague -Dawley rats were randomly divided into three groups (n=12) . Twelve rats as the control group and the remaining rats were to establish a chronic periodontitis model ligated with orthodontic ligature wire on the cervical part of the left maxillary first molar under general anesthesia. All three groups were administered by gavage for 14 days: equal amounts of saline were given to the control and periodontitis groups, and 400 mg/kg concentration of puerarin was given to the puerarin group. All rats were anesthetized after 24 h of the last administration blood was collected from the abdominal aorta, and the serum was centrifuged for the detection of IL-4, IL-10, IL-6, and IFN-γ in peripheral blood, then all rats were executed, some rats separated from the left maxilla, fresh gingival tissue removed from the buccal-palatal side of the left maxillary first molar, and the remaining maxillary bone tissue used for the detection of Micro-CT; some rats subjected to the left maxillary bone specimens taken with the gingival tissues, used for HE staining detection. Results: HE staining showed that inflammatory cell infiltration was significantly reduced in the puerarin group compared to the periodontitis group. ELISA analysis showed that puerarin promoted IL-4 and IL-10 expression and decreased IL-6 and IFN-γ expression levels in serum (P<0.05) . Micro-CT showed that puerarin significantly reduced alveolar bone resorption compared to the periodontitis group (P<0.05) . Conclusion: Puerarin may inhibit inflammation and alveolar bone resorption in experimental periodontitis rats. [ABSTRACT FROM AUTHOR]

The paper described main research content and present situation of wireless networked control system from the aspects of industrial application based on wireless sensor network theory, design of control method, design of scheduling strategy and communication protocol and co-design of control and scheduling. It also discussed research direction of wireless networked control system.

Objective: The aim of this study was to explore differences in serum Tau protein levels and neurodevelopmental prognoses of placental abruption or umbilical cord around neck with hypoxic-ischemic encephalopathy (HIE). Methods: Forty neonates with moderate/severe HIE divided into placental abruption with HIE group (placental abruption with hypoxic-ischemic encephalopathy (PA-HIE) group) (n = 18) and umbilical cord around the neck with HIE group (umbilical cord around the neck with hypoxic-ischemic encephalopathy (UCAN-HIE) group) (n = 22). Healthy term newborns comprised the control group (n = 35). Serum Tau protein levels were measured using an enzyme-linked immunosorbent assay 24 hours (3.50 hours [1.00–24.00]) after birth. Neurodevelopment outcomes were assessed based on the Gesell Developmental Scale at 9 months of age. Results: Serum Tau protein levels were significantly higher in 40 cases (1013 pg/ml [538.04–1190.42]) than in the control group (106.41 pg/ml [64.55–154.71], p =.0001). Serum Tau protein levels in the PA-HIE group (1024.46 pg/ml [657.88–1190.42]) were significantly higher than those in the UCAN-HIE group (892.78 pg/ml [538.04–1179.50], p =.0149). The development quotient score in the PA-HIE group (67.0 [47.0–90.0]) was significantly lower than that in the UCAN-HIE group (81.5 [52.6–100.0]) (p =.0028). The component ratio of neurodevelopmental retardation in the PA-HIE group (44.45%) was significantly higher than that in the UCAN-HIE group (22.73%) (X2 = 13.3138, p =.0013). Conclusions: Compared with the UCAN-HIE group, the serum Tau protein level and the component ratio of neurodevelopmental retardation were significantly higher in the PA-HIE group.
