Effect of HBXIP on biological function and PI3K/Akt signaling pathway of adenoid cystic carcinoma cell line ACC-M MENG Xue, QI Xiao-yu, WANG Qiu-xu, LIU Wei-xian Shanghai Journal of Stomatology    2017, 26 (4): 389-394.   DOI: 10.19439/j.sjos.2017.04.008 Abstract （364）      PDF （4378KB）（1919）       Knowledge map    To study the effect of hepatitis B virus X protein binding protein (HBXIP) on proliferation, migration and invasion of adenoid cystic carcinoma cell line ACC-M, and the possible mechanism of PI3K/Akt signaling pathway. METHODS: HBXIP plasmid was transfected into ACC-M. The cells were divided into experimental group (transfected with plasmid pEGFP-N1-HBXIP) control group (non-transfected group) and blank control group (vector group, pEGFP-N1). RT-PCR was used to detect the expression HBXIP in ACC-M; MTT assay, transwell chamber experiments and scratches over the proliferation of HBXIP were utilized individually to evaluate the influence of HBXIP on ACC-M expression, migration and invasion; Western blotting was used to detect the protein expression of Akt, p-Akt, PI3K, p-PI3K and S100A4 after overexpression of HBXIP. Statistical analysis was performed using SPSS 18.0 software package. RESULTS: MTT results showed that the number of surviving cells of experimental group was significantly higher than the control group (P<0.05); Scratch test results showed that the cell mobility of the experimental group was significantly higher than the control group (P<0.01); Transwell chamber experiments showed that the number of cell invasion of the experimental group was significantly higher than the control group (P<0.01); Western blotting results showed that compared with the control group, the expression of p-Akt, p-PI3K and S100A4 in the experimental group with overexpressed HBXIP was relatively increased. CONCLUSIONS: Overexpression of HBXIP gene promotes ACC-M proliferation, invasion and migration. Further, ACC-M proliferation, invasion and migration may be promoted by increased Akt, PI3K phosphorylation and S100A4 protein expression. Reference | Related Articles | Metrics

The orthodontic therapeutic principles for malocclusions concurring with temporomandibular joint disorders SHEN Gang Shanghai Journal of Stomatology    2021, 30 (4): 337-343.   DOI: 10.19439/j.sjos.2021.04.001 Abstract （830）      PDF （2978KB）（1333）       Knowledge map    The biological nature of temporomandibular joint (TMJ) featuring adaptive remodeling allows for TMJ structural changes in response to external stimuli, including alterations in occlusion and in mandibular posture. Correlative susceptibility exists between malocclusions and TMJ disorders (TMD), evidenced by high incidence of TMD coinciding with skeletal originated malocclusion with facial prognathsim (Angle Class I skeletal II high angle). Clinical manifestations include markedly retruded mandible together with increased overjet, or mandibular transverse deviation, due to condylar pathological resorption. It is critically imperative to execute differential diagnosis between the routine malocclusions and those infringed with TMD. The prime stipulations governing the orthodontic procedures include the patient's notification of the existential TMD conditions prior to any orthodontic interventions, close inspections of TMD developments during the treatment, and a specially designed retention protocol aftermath. For the cases where severe overjet and mandibular displacement occur as a result of TMD, some specific orthopedic modalities can be implemented to improve the occlusion by restoring the shifted mandible. TMD conditions are also expected to be relieved with mandibular repositioning, which encourages new bone formation in the degraded condyles. The newly developed clear version of orthopedic appliances, namely, S8-SGTB, S8-SGHB, S9 and S10 are of promising efficacy in treating this category of patients.

Analysis of three dimensional stability of the hypoplastic maxilla after orthognathic surgery in cleft lip and palate patients YINGWANG Jun-zi, SHEN Shun-yao, LI Biao, SUN Hao, ZHANG Tian-jia, WANG Xu-dong Shanghai Journal of Stomatology    2016, 25 (3): 345-351.   Abstract （400）   HTML （0）    PDF （1222KB）（944）       Knowledge map    PURPOSE: To establish a three dimensional spacial measurement method to analyze the short-term stability of maxilla after orthognathic surgery in cleft lip and palate patients. METHODS: Twenty-five patients with maxillary hypoplasia secondary to cleft lip and palate seeking for orthognathic surgery were included in this study between January 2008 and September 2012. The spiral CT scan for the skull were taken 6 weeks preoperatively (T0), 4 days postoperatively (T1),3 months postoperatively (T2), and 6 months postoperatively (T3) and collected. A three dimensional analytic method for measuring maxilla was set up in ProPlan CMF software, and good repeatability of identification of landmarks was confirmed. Twenty-two indicators to describe the maxillary position and three new angles to describe the maxillary orientation were measured and analyzed. Student's t test was used to analyze the difference between T2 and T3 using SPSS 16.0 software package. RESULTS: In 25 patients with cleft palate there was a translational relapse upwards along vertical axis and a pitch-up relapse of maxilla with an average of 7.46% at the anterior part of the cleft maxilla. The relapse rate was 30.95% in LUCLP, 8.01% in RUCLP, and 34.76% in BCLP, but with no significant difference. Along the horizontal axis, there was a maxillary translational relapse toward noncleft side in both LUCLP and RUCLP group, while a yaw relapse was confirmed with the anterior part of maxilla toward noncleft side and the posterior part toward cleft side. CONCLUSIONS: There is a three-dimensional relapse tendency for the maxilla in the cleft patient postoperatively. The established three-dimensional analytic method well describes the special position of cleft maxilla especially in the translational and rotational movement of maxilla in three different axes comparing with that from lateral cephalometry, thus providing references for accurate measurements in study of the three dimensional maxillary stability after orthognathic surgery.

Experts consensus on diagnostic and therapeutic strategies for malocclusions at early developing stage FANG Bing, JIN Zuo-lin, BAI Yu-xing, WANG Lin, ZHAO Zhi-he, LI Wei-ran, BAI Ding, HE Hong, LIU Yue-hua, HU Min, SONG Jin-lin, CHEN Li-li, CAO Yang, WU Ting-xi, LI Song, LI Huang, SHI Jie-jun, CHU Feng-ting Shanghai Journal of Stomatology    2021, 30 (5): 449-455.   DOI: 10.19439/j.sjos.2021.05.001 Abstract （1116）      PDF （861KB）（1591）       Knowledge map    Early orthodontic intervention remains a controversial notion in current dental care regime. Whilst early orthodontic treatment for children is the province for orthodontic specialists, a growing number of general practitioners, who may not possess sufficient specialty knowledge, are also involved, raising the concerns about the propriety and quality of their treatment modalities. However, orofacial development of children and adolescents is in a very complicated environment. Comprehensive theoretical knowledge and a great wealth of practical experience are required to ensure the final treatment effect. The possible complications should be kept under control and fully informed to patients and their parents. In order to unify and standardize early orthodontic treatment protocol and help to promote healthy and orderly development of early orthodontic treatment, this consensus summarized the practical experience of orthodontic experts from many famous colleges and affiliated hospitals for clinical reference.

METHODS: Sixteen adult patients with bimaxillary protrusion were selected. All cases were treated with clear aligner and their four first premolars were extracted. G6 was designed in all cases. In the experimental group, four miniscrews were inserted at the beginning of treatment to control the teeth in three dimensions; while in the control group, the miniscrews were not applied until obvious roller coaster effect appeared. Paired t test was used to analyze the data with Graphpad Prism 6.0 software package. RESULTS: All the extraction space was closed successfully and the lateral profile was improved significantly. The torque of the upper incisor was under well control and no roller coaster effect happened in the experimental group; while in the control group, the lingual inclination of the upper incisors and open bite of the posterior teeth developed(P<0.05). After the miniscrews intrusion of the upper anterior teeth, the occlusion relationship improved significantly. CONCLUSIONS: Miniscrews effectively prevents and eliminates the roller coaster effect in the process of long-distance space closure with clear aligner. Reference | Related Articles | Metrics

METHODS: A total of 33 patients with buccal mucosal cancer who underwent buccal mucosal cancer radical surgery and resection of angulus oris, and reconstructed with free anterolateral thigh flap transfer and sliding vermilion flap were collected from January 2015 to April 2021 in Department of Oral and Maxillofacial Surgery at Second Xiangya Hospital. Thirty-three patients with buccal mucosal cancer admitted to Department of Oral and Maxillofacial Surgery, Second Xiangya Hospital of Central South University from January 2015 to April 2021 were selected. All patients underwent combined buccal-mandibulectomy and neck radical operation and resection of oral angle, and underwent anterolateral femoral free flap and lip red elastic flap reconstruction. The angulus oris outcome, aesthetics outcome, masticatory efficacy, swallowing and speech function were assessed by FACT-HN (The Functional Assessment of Cancer Therapy-Head and Neck). The mouth opening was measured and recorded. SPSS 19.0 software package was used for statistical analysis of the data. RESULTS: The success rate of free flap transplantation was 100% in 33 patients. Although the aesthetics outcome was decreased at postoperative 1 year compared with that of preoperative duration (P<0.001), there was no significant difference of angulus oris outcome at postoperative 1 year compared with that of preoperative duration (P>0.05). Moreover, the masticatory function was significantly improved at postoperative 1 year compared with that of preoperative duration(P=0.004). However, there was no significant difference of speech and swallowing function at postoperative 1 year compared with that of preoperative duration (P>0.05). The mouth opening was significantly improved at postoperative 1 year compared with that of preoperative duration(P<0.05), and the satisfaction of mouth opening in these patients was 75.7%. CONCLUSIONS: The use of sliding vermilion flap can ideally repair the angulus oris, and offer a novel method to reconstruct defect of angulus oris. Reference | Related Articles | Metrics

Clinical effect of digital impression combined with all-ceramic denture on restoration of 60 patients with dental defects CHEN Li-rong, LIANG Xue-jin, YANG Feng-ying, LUO Hao Shanghai Journal of Stomatology    2022, 31 (3): 313-317.   DOI: 10.19439/j.sjos.2022.03.018 Abstract （320）      PDF （760KB）（527）       Knowledge map    PURPOSE: To analyze the clinical effect of digital impression combined with all-ceramic denture restoration on patients with dental defects. METHODS: A study was conducted on 120 patients with dental defects admitted to Dongfeng Stomatological Hospital from June 2018 to June 2020. The two groups of patients were randomly divided into digital imprinting modules and silicone rubber imprinting modules using a random number table method. There were 60 cases in each group. The silicone rubber imprint module used traditional silicone impression combined with all-ceramic denture restoration, while the digital imprint module used digital impression combined with all-ceramic denture restoration.The clinical efficacy of the two groups was observed. Gingival index (GI), periodontal index (PI) before dental restoration, during dental restoration and 6 monthes after dental restoration were compared. The adjacent surface contact conditions, occlusion and adverse reactions of the two groups were compared. SPSS 22.0 software package was used for statistical analysis. RESULTS: The two groups of patients selected grade A and grade B for the evaluation of the restoration when the restoration was completed. The number of patients who chose grade A for the digital imprint module was more than that of the silicone rubber imprint module,but there was no significant difference(P>0.05). Six months after the tooth was worn, GI and PI indexes of the two groups of patients increased. GI and PI indexes of the silicone rubber stamping module were significantly higher than those of the digital stamping module(P<0.05). When dental restoration was completed and 6 months after the tooth was replaced, the pass rate of contact between the adjacent surfaces of the imprinting module patients was significantly higher than that of the silicone rubber imprinting module(P<0.05). When dental restoration was completed, the occlusion of the digital imprinting module patients was significantly better than that of the silicone rubber imprinting module(P<0.05). Six months after wearing the denture, there was no significant difference in occlusion between the two groups of patients(P>0.05). When dental models of the two groups of patients were taken, the incidence of adverse reactions in patients with digital imprints was significantly lower than that of silicone rubber imprints(P<0.05). CONCLUSIONS: The use of digital impressions combined with all-ceramic restorations to repair patients with dental defects can effectively improve the treatment effect, improve prognostic GI and PI indexes of the patients, increase the pass rate of the adjacent surface contact and occlusion of the tooth, and reduce the process of dental restoration. The incidence of adverse reactions are minimal, with good prognostic effects. It is worthy of clinical application. Reference | Related Articles | Metrics
