Abstract
BACKGROUND Carbonic anhydrase 1 (CA1) has been found to be involved in osteogenesis and osteoclast in various human diseases, but the molecular mechanisms are not completely understood. In this study, we aim to use siRNA and lentivirus to reduce or increase the expression of CA1 in Dental follicle stem cells (DFSCs), in order to further elucidate the role and mechanism of CA1 in osteogenesis, and provide better osteogenic growth factors and stem cell selection for the application of bone tissue engineering in alveolar bone fracture transplantation. METHODS The study used RNA interference and lentiviral vectors to manipulate the expression of the CA1 gene in DFSCs during in vitro osteogenic induction. The expression of osteogenic marker genes was evaluated and changes in CA1, alkaline phosphatase (ALP), Runt-related transcription factor 2 (RUNX2), and Bone morphogenetic proteins (BMP2) were measured using quantitative real-time polymerase chain reaction (qRT-PCR) and Western blotting (WB). The osteogenic effect was assessed through Alizarin Red staining. RESULTS The mRNA and protein expression levels of CA1, ALP, RUNX2, and BMP2 decreased distinctly in the si-CA1 group than other groups (p < 0.05). In the Lentivirus-CA1 (LV-CA1) group, the mRNA and protein expressions of CA1, ALP, RUNX2, and BMP2 were amplified to varying degrees than other groups (p < 0.05). Apart from CA1, BMP2 (43.01%) and ALP (36.69%) showed significant upregulation (p < 0.05). Alizarin red staining indicated that the LV-CA1 group produced more calcified nodules than other groups, with a higher optical density (p < 0.05), and the osteogenic effect was superior. CONCLUSIONS CA1 can impact osteogenic differentiation via BMP related signaling pathways, positioning itself upstream in osteogenic signaling pathways, and closely linked to osteoblast calcification and ossification processes.

Abstract
With a limited alveolar bone position, there is a high risk that mini-screws (MS) implants could cause damage to the adjacent teeth. To reduce this damage, the position and tilt angle of the MS must be optimized. The aim of this study was to assess the effect of MS implantation angle on the stress exerted on adjacent periodontal membrane and roots. A three-dimensional finite element model containing dentition, periodontal ligament, jaw and MS were established based on the CBCT images and MS scanning data. The MS was first inserted perpendicular to the surface of the bone at specific locations and then tilted at an angle of 10° and 20° to the mesial and distal teeth, respectively. The stress distribution in the periodontal tissue of the adjacent teeth was analyzed after MS implantation at different angles.The stress on the adjacent tooth root and periodontal ligament was most uniformly distributed when the MS was inserted vertically. It changed 9.4-97.7% when the axis of MS was tilted at 10-degree and 20-degree angles from the point of vertical insertion. The stresses experienced by the periodontal ligament and the root are similar. When the horizontal angle of the MS insertion was changed, the MS was closer to the adjacent tooth, resulting in greater stress near the PDL and root. It was recommended to insert the MS vertically into the alveolar bone surface to avoid root damage due to excessive stress.

Abstract
Scarring is the primary factor of maxilla growth restriction among people who have undergone cleft palate repair surgery. p38 mitogen-activated protein kinase (p38MAPK) promotes fibrosis in a variety of organs. However, its role in post-surgery scarring on the hard palate has not been fully understood. This study is designed to investigate the role of p38MAPK in scar formation and maxilla growth of rats. We removed the mucosa on the hard palate of rats and applied the p38MAPK silencing adenovirus vector on it two weeks after surgery. Then the scarring tissue and maxilla growth were evaluated by histological and morphological examination. The effect of p38MAPK silencing on scarring-related genes in fibroblasts was also studied. We found that local injection of Ad-p38MAPK-1 in vivo effectively reduces the expression of p38MAPK and scarring-related proteins and weakens the impact of scarring on the width of the hard palate. Mechanistically, p38MAPK silencing inhibits the expression of α-smooth muscle actin (α-SMA) via mediating the production and nuclear localization of myocardin-related transcription factor A (MRTF-A) in fibroblasts. These results reveal a molecular pathway of scar formation involving p38MAPK/MRTF-A stimulation and support targeting p38MAPK as a potentially effective treatment for post-surgery scarring on the hard palate.

Abstract
Background Cleft lip repair surgery always results in visible scarring. It has been proved that scar formation can be reduced by inhibiting the p38 mitogen-activated protein kinases (p38MAPKs) signaling pathway. However, the interaction between p38MAPK and Smads in scar formation is still controversial. Methods This study was designed to investigate whether inhibition of p38MAPK reduces postoperative scar formation of cleft lips on rabbits via the Smads signaling pathway. Scar models in rabbits after cleft lip surgery were created and their fibroblasts were extracted. Then the expression of p38MAPK was disturbed by adenovirus in vitro and Vivo. The scar thickness was measured and scar tissues were excised for Sirius red staining and immunohistochemistry to detect the expression of type I collagen (col I), type III collagen (col III), and α-smooth muscle actin (α-SMA). The underlying mechanisms of p38MAPK knockdown on the extracellular matrix and Smad signaling pathway were invested in vitro using the EdU assay, Western blot, RT PCR, and immunofluorescence. Results p38MAPK knockdown suppresses the expression of p-smad3 and p-smad2 in fibroblasts, modulating the expression of its target genes, such as α-SMA, col I, and col III. When Ad-P38MAPK-1 was injected into lip scar, it reduced the expression of scar-related genes and scar thickness when compared to the negative control groups. Conclusions In rabbits, inhibiting p38MAPK expression prevents scar proliferation through inhibiting the Smad signaling pathway after cleft lip surgery.

Abstract
OBJECTIVES This study aims to investigate the incidence and severity of obstructive sleep apnea (OSA) in cleft patients with velopharyngeal insufficiency (VPI) after pharyngeal flap surgery (PFS) and explore the influence of operation age. METHODS A retrospective study was conducted in 82 cleft patients after PFS. The patients were divided into two groups according to their age at the time of surgery. The incidence and severity of OSA were assessed at least 1.2 years (mean 6.0 years) postoperatively by polysomnography (PSG). RESULTS The incidence rates of OSA were 20% in the adult group and 31% in the child group. No significant difference was found between the two groups (P=0.289). Patients with OSA in the adult and child groups were classified into different levels of severity (mild, moderate, severe) according to the apnea hypoventilation index (AHI). No statistically significant difference in the severity of OSA was found between the two groups (P=0.079). CONCLUSIONS Some patients still have OSA average of 6.0 years after PFS, and operation ageis unrelated to the incidence and severity of OSA.

Abstract
BACKGROUND Burning mouth syndrome (BMS) is characterized by burning sensation of the oral mucosa. There is a lack of effective treatment. In recent years, a special subtype of BMS has been reported, in which oral burning sensation is alleviated after chewing, speaking, or dopaminergic drug delivery. Currently, there are few reports about the subtype of BMS in China. This study was a retrospective analysis of the clinical data of BMS patients sensitive to dopamine agonist at our hospital, aiming to improve the recognition on this disease.
CASE SUMMARY Eight patients diagnosed with dopamine agonist responsive BMS at the Liaocheng People's Hospital from January 1, 2017 to June 30, 2020 were recruited. The clinical manifestations, treatment, and prognosis were retrospectively analyzed. There were three male and five females in the eight patients. The median age was 56 years (range, 46-65 years). All the eight patients showed burning pain in the mouth. The symptoms were mild in the morning and severe in the evening, and alleviated after chewing, talking, and other oral activities. Four patients were accompanied by restless legs syndrome (RLS). Family history of RLS was positive in two patients. All patients were treated with pramipexol, and symptoms were basically relieved after 2-8 wk.
CONCLUSION Dopamine agonist responsive BMS is a special subtype of BMS, which is alleviated after oral activities. Dopamine receptor agonist is an effective treatment.

Abstract
BACKGROUND Oral lichen planus (OLP) is a chronic inflammatory disorder, and it can affect normal oral function. The conventional treatments for OLP are not always effective, and relapse easily occurs. Therefore, treatment of OLP is difficult and challenging. In this study, we evaluated over a long period the clinical efficacy of surgical excision and acellular dermal matrix (ADM) grafting in patients with refractory OLP.
CASE SUMMARY Eleven patients with refractory OLP underwent a standardized protocol of surgical excision and ADM grafting. The condition of the area of the grafted wound, the intraoperative maximum mouth opening, pain, and clinical healing were assessed at postoperative follow-up visits. All patients had a flat surgical area with similar mucosal tissue coverage and local scar formation. Patients had no irritation and pain in their mucous membranes when eating acidic and spicy food. All patients’ mouth openings returned to normal within 2-6 mo after surgery. During follow-up, none of the patients had recurrence of OLP after surgery. The longest follow-up was 11 yr and the shortest was 6 mo, and none of the patients relapsed during follow-up.
CONCLUSION Surgical excision and ADM grafting could be an effective method to treat refractory OLP.

Abstract
Objective: To investigate the characteristics of asymmetric hearing loss in left and right ears of patients with occupational noise-induced deafness and to explore the possible causes of asymmetric hearing loss. Methods: A total of 423 cases of occupational noise-induced deafness diagnosed in Guangdong Province Hospital for Occupational Disease Prevention and Treatment from May 2015 to May 2018 were investigated retrospectively. On the basis of three consecutive pure tone audiometry (PTA) with intervals of more than 3 d in hospital, the minimum of hearing threshold of each frequency and the frequency response threshold of auditory steady-state response (ASSR) , and based on the GBZ 49-2014 "Diagnosis of Occupational Noise-induced Deafness". The statistical analysis of Wilcoxon signed rank test and Spearman correlation analysis were carried out by nonparametric test. The hearing threshold weight of PTA and the response threshold of ASSR were tested and compared from different dimensions according to sex, age, length of service of exposure noise, diagnosis grade and so on. Results: There were 369 male (87.23%) and 54 female (12.77%) ; the age was (41.8±7.6) years; the length of service was (10.1±6.2) years. The weighted values of left ear PTA and ASSR were higher than those of right ear (P<0.001) . The weighted values of left ear PTA and ASSR were higher than those of right ear (P<0.05) in men, patients with age ≤ 40 and 41-60 years, 3-9 years of service, and patients with mild grade (P<0.05) . After the equalization of characteristic variables, the weighted values of left ear PTA and ASSR were also higher than those of right ear (P<0.05) . There was a positive correlation between the weighted value of PTA and the weighted value of ASSR (P<0.001) . Conclusion: There is asymmetry in hearing loss of patients with occupational noise deafness, and hearing loss in the left ear is higher than that in the right ear.

Abstract
OBJECTIVE In this study, the clinical effect of negative pressure drainage-assisted irrigation (NPDI) technique was evaluated in treating maxillofacial space infection (MSI) by comparing with traditional technique. METHOD A prospective study was conducted in 58 patients with MSI. The patients were randomly divided into two groups based on different treatment techniques. Thirty patients receiving NPDI were included in NPDI group, and 28 patients receiving traditional technique were included in traditional group. Case data (gender, age, etiology, concurrent illness, diabetes, involved spaces, preoperative white cell count, airway control method) and clinical effect (postoperative hospital stay, total cost of admission) for the two groups were analyzed. RESULTS Patients in both groups were cured clinically. There were no significant differences in gender, age, etiology, concurrent illness, diabetes, involved spaces, preoperative white cell count, and airway control method in NPDI group and traditional group (p > .05). The postoperative hospital stay and the total cost of admission in the NPDI group were significantly lower than the traditional group (p < .001). CONCLUSION Negative pressure drainage-assisted irrigation used in the treatment of MSI can shorten the postoperative hospital stay, reduce the total cost of admission, and show favorably clinical effect. It is a clinically recommended method for MSI.

Abstract
OBJECTIVE The purpose of the present work was to investigate the association between forkhead box E1 (FOXE1) and the risk of non-syndromic cleft lip with or without cleft palate (NSCL/P). MATERIALS AND METHODS Relevant studies were searched in several professional databases up to 31 July 2019. The pooled odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated using a fixed-effect model or a random-effect model to analyse the relationship between FOXE1 polymorphisms and NSCL/P. RESULTS A total of four single nucleotide polymorphisms (SNPs), including rs3758249, rs4460498, rs1443434 and rs10217225, were analysed. The overall findings showed that FOXE1 rs4460498 was statistically associated with NSCL/P (including cleft lip with or without cleft palate (CL/P) and cleft palate only (CPO)). Genotypes CC and CT of rs4460498 were significantly more closely correlated with NSCL/P (including CL/P and CPO) than genotype TT (NSCL/P: TT vs CC, OR = 0.630, P = .000; TT vs TC + CC, OR = 0.775, P = .020; CL/P: TT vs CC, OR = 0.664, P = .000; TT vs TC + CC, OR = 0.738, P = .006. CPO: TT vs CC, OR = 0.761, P = .027; TT vs TC + CC, OR = 0.792, P = .045). For rs10217225, only the TT genotype might have contributed to the elevated risk of CL/P (TT vs CC OR = 2.236, P = .000). The other FOXE1 polymorphisms were not associated with NSCLP, CL/P or CPO. CONCLUSION The meta-analysis provided confirmation that the polymorphism of FOXE1 rs10217225 was correlated with an increased risk of CL/P, and the polymorphism of FOXE1 rs4460498 was a protective factor for NSCL/P, including CLP and CPO.

Abstract
The aim of the present study was to improve methods for the suspension culture of mouse palatal shelves by comparing the expression of platelet-derived growth factor receptor (PDGFR)-α in palatal shelves in vivo, to that in vitro. The palatal shelves of C57BL/6 mouse embryos were obtained on gestation days (GDs) 13.5, 14.5, 15.0 and 15.5 for in vivo experiments. The palatal shelves were removed and observed under a stereomicroscope to investigate palatal development. For in vitro experiments, the palatal shelves were dissected under a stereomicroscope on GD 13.5 and then subjected to rotary culture for 0, 24, 36 or 48 h. The expression of PDGFR-α at different time points was detected by immunohistochemical staining and western blot analysis. Both methods of analysis displayed PDGFR-α expression in mesenchymal and epithelial cells at GD 13.5, 14.5, 15.0 and 15.5, in vivo and in vitro. The level of PDGFR-α expression peaked on GD 14.5. The expression of PDGFR-α in palatal shelves in in vitro rotary culture was consistent with that in vivo. Therefore, the novel technique of palatal rotary organ culture presented in the current study could provide a good model for studying the mechanism of pathological palatal fusion in vitro. Additionally, the present study further confirmed that PDGFR-α gene expression was associated with the development of palatal shelves.

Abstract
BACKGROUND To systematically evaluate the effect of bone morphogenetic protein-2 (BMP-2) and iliac cancellous bone graft (ICBG) on alveolar cleft bone grafting (ACBG) in cleft lip and palate. METHOD Online databases were searched for case-control studies related to the application of BMP-2 and ICBG in ACBG. RESULT Meta-analysis showed no significant statistical difference in the filling rate (OR = 4.1, 95% CI (0.06, 2.63)), the volume of bone graft area (OR=-0.42, 95% CI (-1.44, 0.60)), the height of bone graft area (OR = -21.38, 95% CI (-23.00, -19.76)), the density of bone graft area (OR = 0.43, 95% CI (-0.79, 1.64)), the failure rate of bone graft (OR = 0.02, 95% CI (-0.03, 0.06)), infection after operation, and the rate (OR = 0.20, 95% CI (0.05, 0.73)) and the incidence of postoperative oronasal fistula (OR = 4.1, 95% CI (0.06, 2.63)) between BMP-2 and ICBG in ACBG. However, there were obvious statistical differences in operative time (OR = -3.64, 95% CI (-7.35, 0.06)) and the length of hospital stay (OR = -1.97, 95% CI (-2.41, -1.53)). CONCLUSION The meta-analysis shows that there is no significant difference between BMP-2 and ICBG in filling rate, volume, density, failure rate, and the occurrence of oronasal fistula after ACBG. There were significant differences between BMP-2 and ICBG in the operation time and hospitalization time of ACBG. Compared with ICBG bone graft, BMP-2 has more advantages in ACBG such as remaining area height, postoperative infection rate, operative time, and length of hospital stay.

Abstract
OBJECTIVE The purpose of the study is to investigate the relationship between dental calcification stages (DCS) and cervical vertebral maturation stages (CVMS) in patients with unilateral complete cleft lips and palates (UCLP) and to provide a theoretical basis for the treatment time selection of cleft lip and palate (CLP) patients. METHODS A total of 123 UCLP patients and 215 non-CLP subjects were selected. The DCS of the left mandibular canine, premolar, and second molar in non-CLP subjects and on both cleft sides of UCLP patients were assessed utilizing the Demirjian method. CVMS was observed utilizing the Baccetti method. The results were analyzed by Spearman rank correlation, and the correlation coefficients were compared. RESULTS There was a correlation between the CVMS and the DCS of the left mandibular canine, the first premolar, the second premolar, and the second molar in the non-CLP subjects and on both cleft sides of the UCLP patients (r=0.762-0.864, P<0.05; r=0.809-0.914, P<0.05, respectively). The correlation between the CVMS and the DCS of the mandibular first premolar was highest among the UCLP patients. Except for the first and the second premolars of UCLP females, the correlation between the DCS and the CVMS of the other teeth did not differ among the non-CLP subjects (P>0.05). CONCLUSIONS DCS can be utilized as a biological index to determine the growth development statuses. The correlation between the CVMS and the DCS of the mandibular first premolar was the highest.

Abstract
Little information is available concerning the prevalence of caries among patients with oral clefts in Eastern China. Consecutive patients aged 6-18 with oral clefts were recruited. Patients were stratified into 2 groups according to their ages, namely Group I with aged 6-12 and Group II with aged 13-18. For each age group, the children were further divided into three subgroups according to the types of oral clefts they had: cleft lip/cleft lip and alveolus (CL), cleft palate only (CP), and cleft lip and palate (CLP). Dental caries were examined by using the decayed, missing, and filled index for primary teeth (dmft) and Decay, Missing and Filled index for Permanent teeth (DMFT) according to criteria of the World Health Organization. 268 eligible patients with oral clefts were included in the study. The mean DMFT for Group I was 1.77 (SD2.58) while that for Group II was 6.96 (SD4.35). The mean DMFT was statistically significant different between the age group I and age group II (t=12.21, P<0.05). In Group I, the dmft scores was 4.68 (SD3.67) for CL group, while that for the CP group was 7.36 (SD3.93), and that for the CLP group was 5.72 (SD 3.87). The mean dmft was no statistically significant different among cleft types (F=3.13, P>0.05). Also in Group I, the mean DMFT was 1.56 (SD2.18) for CL group, while that for the CP group was 1.24 (SD 1.81) and that for the CLP group was 2.08 (SD2.96). There were no statistically significant different in mean DMFT among different cleft types (F=1.09, P>0.05). In Group II, the mean DMFT was 6.06 (SD3.97) for CL group while that for the CP group was 7.71 (SD 4.94) and that for the CLP group was 7.05 (SD4.32). No significant difference was shown in the mean DMFT among different cleft groups (CL, CP, and CLP) (F=0.55, P>0.05). During assess the prevalence of dental caries among Eastern Chinese with oral clefts; the study confirmed that the prevalence of caries was increased with increasing age for oral clefts patients. It was also demonstrated that there was no significant difference in the mean dmft/DMFT scores among different cleft types.

Abstract
It's clear that environmental factors play a role in the aetiology of orofacial clefting (OFC) and an important area of future research will be to unravel interactions that occur between candidate genes and environmental factors during early development of the embryo. Periconceptional folic acid supplementation may reduce the risk of OFC. Polymorphisms in the methylenetetrahydrofolate reductase (MTHFR) gene reduce availability of 5-methylenetetrahydrofolate, the predominant circulating form of folic acid. To determine the effect of MTHFR gene mutation on murine embryonic palatal mesenchymal (MEPM) cells and the interaction with folic acid supplement, we used RNAi study in the primary cultures of MEPM cells. The cells of MTHFR gene silencing grew slower and the apoptosis cell number was more than the cells of control. Supplement with 20 microg/ml folic acid was the best to preventing teratogenic effect of MTHFR gene silencing. By flow cytometry analysis of cell cycle, results were shown that the MEPM cells were retarded in G(0)/G(1) after MTHFR gene silencing. While using 20 microg/ml folic acid supplements could make cell transit the G(1)/S restriction point and the cells growth was close to normal level.
