Objective@#To investigate the clinical effects of sinus elevation surgery and implant restorationdue to insufficient bone massafter tooth extraction in patients with odontogenic maxillary sinusitis (OMS) and to provide a reference for use in clinical practice.@*Methods@#This study was reviewed and approved by the Ethics Committee, and informed consent was obtained from the patients. Forty-five teeth were extracted from patients with OMS in the maxillary posterior area (the study group). Sinus elevation and implantation were performed due to insufficient bone height in the implant area 6-8 months after tooth extraction in the study group. Forty-eight teeth were extracted from patients without "OMS" in the maxillary posterior area (the control group), and sinus elevation and implantation were performed due to insufficient bone height in the implant area 6-8 months after tooth extraction inthe control group. In the study group, 13 cases of discontinuous maxillary sinus floor bone and residual alveolar bone height of the maxillary sinus floor less than 4 mm were addressed with lateral wall sinus elevation, and the other 32 cases were addressed with crest-approach sinus elevation. In the control group, 8 cases of residual alveolar bone height less than 4 mm in the maxillary sinus floor were addressed with lateral wall sinus,and the other 40 cases were addressed with crest approach sinus elevation. Restorations were placed 6 to 8 months after surgery. The patients were followed up 21 days, 3 months, and 8 months after implantation and every 6 months after the placement of the restorations. The sinus bone gain (SBG), apical bone height (ABL) and marginal bone loss (MBL) were statistically analyzed 24 months after the restoration.@*Results@#The average preoperative mucosal thickness in the 45 patients in the study group was (1.556 ± 0.693) mm, which was significantly larger than that in the control group (1.229 ± 0.425) mm (P<0.001). There were no perforations in either group. Twenty-four months after restoration, there was no significant difference in the SBG, ABH or MBL between the two groups (P>0.05).@*Conclusion@#After the extraction of teeth from patients with OMS, the inflammation of the maxillary sinus decreased, and the bone height and density in the edentulous area were restored to a certain degree. The effects of sinus floor lifting surgery and implant restoration do not differ between patients with and without OMS.

Objective@#To explore the effects of group sports game intervention on social ability and quality of life of children with austism spectrum disorders (ASD),so as to provide reference for rehabilitation intervention of social and quality of life of children with ASD.@*Methods@#From September 2021 to January 2022, 72 children with ASD aged 4-6 in the children s rehabilitation department of Xiangyang Central Hospital were selected to participate in the study, and were randomly divided into experimental group ( n =36) and control group ( n =36). The control group received routine rehabilitation training (including individual sports game training), and the experimental group replaced individual sports game training with group sports game training on the basis of routine rehabilitation.The course content mainly included three parts: warm up before class, group sports games and relaxation after class. The course combined social skills with sports games, and was carried out in a group form (divided into 12 groups with 3 people in each group), and was trained five times a week for 60 minutes, for a total of 12 weeks. The scores of Childhood Autism Rating Scale (CARS), Autism Treatment Evaluation Checklist (ATEC), Social Responsiveness Scale (SRS) and Pediatric Quality of Life Inventory Version 4.0 Generic Core Scales (PedsQL 4.0) were observed before and after treatment. t-test and χ 2 test were used for statistical analysis.@*Results@#There was no significant difference in SRS scores between the experimental group and the control group before intervention ( t =-0.63, P >0.05). After the intervention, the total response rate in the experimental group was 83.33 %, higher than 41.67% in the control group χ 2=13.33, P <0.05),and the SRS scores decreased in the experimental group and control group ( t =17.75,8.71, P <0.05). The SRS scale score of the experimental group Social perception (17.67±4.12) , social cognition (30.33±4.99) , social communication (50.33±9.39) , social motivation (24.25±6.78) scores and total scores ( 152.67± 25.82) were lower than those of the control group(22.17±5.34，36.00±4.13，62.58±11.07，34.42±7.13，186.33±29.03)( t = -4.88，-2.03，-2.13，-3.58，-3.01， P ＜0.05).After the intervention, the scores of social function (53.33±18.01) and total score (283.83±51.83) on PedsQL 4.0 scale in experimental group were higher than those in control group(23.33±15.13，218.00±39.01) ( t =4.42，3.52， P ＜0.05). After the intervention, Autism Treatment Evaluation Scale (ATEC) scores of experimental groups(44.33±14.72) was lower than that in control group ( 59.33±16.95)( t =-2.32, P ＜0.05).@*Conclusion@#The intervention of group sports game has a significant effect on improving social ability and life quality of children with ASD.

@#Abstract: Objective To establish a risk prediction model for nosocomial infection in preterm very low birth weight infants, and conduct internal validation. Methods A total of 206 cases of very low birth weight premature infants hospitalized in the Department of Neonatology of Union Hospital Affiliated to Tongji Medical College from January 2018 to June 2020 were included in this study, factors that may affect the nosocomial infection of children were collected, and the infants were divided into two groups according to whether there is nosocomial infection. The influencing factors were compared between the two groups, and multivariate Logistic regression analysis was performed after screening variables with LASSO regression. According to the results of multi factor analysis, the nomogram model was constructed and verified internally. Results A total of 29 of 206 children had nosocomial infection (14.08%), and 33 pathogenic bacteria were detected, including 23 Gram-negative bacteria, 9 Gram-positive bacteria and 1 fungus. The results of multivariate logistic regression analysis based on LASSO regression showed that the risk factors for nosocomial infection of VLBW premature infants were 28-31+6 weeks of gestation, amniotic fluid pollution, mechanical ventilation, indwelling gastric tube, unreasonable use of antibiotics, and hospitalization time ≥ 7 days. The protective factors were Apgar score ≥ 7 points at 1 min and breast feeding accounting for 50% or more (P<0.05). The Area Under Curve (AUC) of ROC curve of nomogram model was 0.946 [95%CI(0.923, 1.000)]. The calibration curve showed that the probability of hospital infection predicted by the model was basically consistent with the actual probability. The decision curve showed that when the probability threshold of nomogram model to predict the risk of nosocomial infection of very low birth weight premature infants was 0-0.85, the net rate of return was greater than 0. Conclusion Preterm infants with extremely low birth weight are at high risk of nosocomial infection, mainly affected by factors such as gestational weeks, hospitalization time, amniotic fluid pollution, etc. The nomogram model constructed by the above factors has high accuracy and discrimination for predicting nosocomial infection in such children.

@#The jaw and femur are commonly used sites in basic research for modeling bone defects or inserting implants. An increasing number of studies have identified that the jaw and femur indeed show great differences in embryonic development and growth, histomorphology and bone metabolism. A literature review showed that, compared with the femur, the main osteogenic pathway of the jaw may have better osteogenic ability, and its stem cells have better proliferation and osteogenic differentiation ability. However, the jaw structure is less regular, the osteogenic differentiation ability of its osteoblasts is mineralization slightly weak, and the immune cells of the jaw are more sensitive to cytokines. These may be the reasons why the osseointegration of the jaw implant is different from that of the femur in animal experiments, but its specific mechanism has not been clarified.

@#Patients seeking implantation often have several systemic diseases, which will introduce complications to treatment. This paper reviews the risk assessments and prevention of systemic diseases in patients with oral implant therapy with the relevant literature. The patients with cardiovascular diseases are prone to stroke and cardiac arrest, and anticoagulants and antihypertensive drugs will complicate cases. The potential risks of endocrine system diseases are infections and crises caused by unstable hormone levels. The risks of respiratory diseases are dyspnea and swallowing devices. The difficulty of treating patients with neuropsychiatric diseases is attributable to poor cooperation and adverse effects of the drugs. Bone and joint system diseases may decrease the success of implantation. Hematological system, digestive system and kidney diseases may lead to hemorrhage. By inquiring about detailed medical and medication history, evaluating vital signs and detecting important objective indicators, performing targeted measures, discussing with specialists, and observing patients closely, clinicians can avoid the abovementioned risks.
