Abstract
OBJECTIVE To observe the clinical efficacy of pulpotomy in patients of different ages and to explore the occurrence and characteristics of pulpal calcification. METHODS A total of 77 patients who underwent pulpotomy for mature permanent premolars and molars with caries-derived pulp exposure in the Department of General Dentistry, Peking University School and Hospital of Stomatology from October 2019 to August 2022 were selected. Pulpotomies were performed in a single visit using iRoot BP Plus bioceramic material as pulp capping agent. The patients were divided into three groups according to age: 25 cases in the adolescent group (11-20 years old) with a mean age of (15.88±2.19) years; 27 cases in the middle-aged group (21-50 years old) with a mean age of (34.59±8.67) years; and 25 cases in the elder-aged group (51-83 years old) with a mean age of (63.84±7.40) years. The patients were reviewed 1 year after the operation to evaluate the clinical efficacy and to record the formation of calcified bridge, thickness of calcified bridge, and pulp calcification index (PCI). RESULTS There was no statistically significant difference between the three groups in terms of gender, dentition, and tooth position (P > 0.05). The 1-year postoperative follow-up rate was 85.71% (66/77), including 88.00% (22/25) in the adolescent group, 85.19% (23/27) in the middle-aged group, and 84.00% (21/25) in the elder-aged group. The 1-year follow-up clinical success rates of the three groups were 95.45% (21/22), 91.30% (21/23), and 95.24% (20/21), respectively, with no statistically significant difference (P>0.05). Among the clinical success cases, calcified bridges appeared in 12 cases (57.14%, 12/21) in the adolescent group, 8 cases (38.10%, 8/21) in the middle-aged group, and 3 cases (15.00%, 3/20) in the elder-aged group, with statistically significant differences (χ2= 7.810, P = 0.020 < 0.05). The difference was statistically significant (F = 4.434, P = 0.020 < 0.05) when comparing the thickness of calcified bridges among the three groups. Calcified bridge thickness was negatively correlated with age (r = -0.516, P < 0.05). The changes in pulpal calcification index ΔPCI were 0.67 ± 0.58, 0.43 ± 0.51, and 0.25 ± 0.52, respectively, with statistically significant differences among the three groups (F = 3.404, P = 0.040 < 0.05). CONCLUSION Pulpotomy for caries-derived pulp exposure in elderly patients could also achieve a high success rate. The incidence of calcified bri-dges after pulpotomy and the acceleration of pulpal calcification were age-related. The adolescent group was more likely to form calcified bridges and also showed more pronounced accelerated root canal calcification.

Abstract
OBJECTIVE To understand the clinical characteristics about sequence diagnosis and treatment of oral complications in patients with Sjögren's syndrome (SS) through retrospective analysis, and to provide some guidance for clinical work. METHODS Some SS patients who underwent oral sequence management in the Department of General Dentistry, Peking University School and Hospital of Stomatology from January 2015 to September 2021 were enrolled. For the SS patients included in this study, a comprehensive oral examination was performed, including parotid region examination, oral mucosal exa-mination, dentition examination, dental examination, periodontal examination, unstimulated salivary flow rate, Candida infection and radiological imaging examination. According to the examination results, the patients were given fluoride application, antifungal treatment, root canal therapy, direct filling repair, and indirect repair treatment in sequence and the results recorded. RESULTS A total of 9 patients with SS, with 4 primary SS patients (pSS) and 5 secondary SS patients (sSS) were enrolled in the study. For all the 9 patients, the average age was (49.2±16.2) years and the median xerostomia duration 5 years. The unstimulated salivary flow rate of the 9 patients was all less than 1 mL/10 min. Eight of the 9 cases was diagnosed as oral Candidiasis, with positive salivary Candida culture result (>200 cfu/mL), and 1 of the 9 cases was not. The average decay, missing, filling teeth (DMFT) was 24.8±4.2; the average decay, missing, filling tooth surfaces (DMFS) was 59.2±21.9, the average incisal caries was 2.5±1.3, and the average number of crown restorations at baseline was 4.5±3.6. All the 9 SS patients were applied with topical fluoride usage, and 8 were prescribed with antifungal treatment. One sSS patient was conducted with filling restoration treatment, one pSS patient was conducted with full mouth rehabilitation, and the remaining 7 patients were conducted with direct filling combined with fixed repair treatment. The average 3.2 full crown restorations in 6 patients had to be removed and restored because of secondary caries, and 3 of the 9 patients underwent implant denture restorations finally. CONCLUSION Management of oral complications in SS patients needs to be carried out in sequence. A comprehensive examination and diagnosis should be carried out first, followed by infection control, and then restoration of oral function at last.

Abstract
OBJECTIVE To investigate the effect of Erchen Decoction on iron homeostasis in mice with nonalcoholic fatty liver disease (NAFLD) and its mechanism for regulating iron transport in spleen cells. METHODS Thirty male C57BL/6J mice were given a high-fat diet for 12 weeks and randomized (n=6) at the 7th week for gavage (3 times a week) of drinking water (NAFLD model group), Erchen Decoction at low, medium and high doses (7.5, 15, and 30g/kg, respectively), or polyene phosphatidyl choline (PPC; 9.12 mg/kg), with another 6 mice with low-fat and low-sugar feeding as the control group. The active components of Erchen Decoction were determined by HPLC-MS. Lipid accumulation in the liver was evaluated by HE staining and Nile red staining. Prussian blue staining was used to observe iron content in the spleen. The iron ion content in the liver tissue was detected using a detection kit. The expressions of ferroportin1 (Fpn1), transferrin receptor (TfR), Steap3, HO-1, Ter-119, CD163 and CD68 were detected using Western blotting, immunohistochemistry and immunofluorescence staining. RESULTS Medium- and high-dose Erchen Decoction partially reversed the increase of lipid accumulation in the liver of NAFLD mice and showed better lipid-lowering effect than PPC. The NAFLD mice showed significantly decreased iron ion content in the spleen with increased hepatic and serum iron contents (P < 0.05), decreased TfR protein expression (P < 0.05), and increased Fpn1 and Steap3 protein expressions (P < 0.05), and these changes were significantly improved by the drug interventions. Erchen Decoction also improved the function of CD163 macrophages in the spleen of NAFLD mice by up-regulating the expression of HO-1 (P < 0.05). CONCLUSION Erchen Decoction can alleviate high-fat diet-induced iron metabolism disorder by improving the iron ion transport ability of the spleen cells to delay the progression of NAFLD.

Abstract
Objective To explore the effectiveness of folded transverse superficial epigastric artery perforator flap in repairing the large penetrating defect after buccal carcinoma resection. Methods Between January 2019 and June 2021, 12 patients with buccal squamous cell carcinoma were treated. There were 6 males and 6 females with an average of 66.9 years (range, 53-79 years). The pathological stage was T3a-T4b, and the preoperative mouth opening was (3.08±0.46) cm. The disease duration ranged from 6 to 24 months, with an average of 15 months. After buccal carcinoma radical resection and neck lymph node dissection, the penetrating defects in size of 8 cm×6 cm to 16 cm×8 cm and in depth of 0.5-1.5 cm were remained. The transverse superficial epigastric artery perforator flap in size of 8 cm×6 cm to 14 cm×8 cm were harvested and folded to repair the penetrating defects. The donor site was sutured directly. Results All 12 skin flaps survived after operation, and the wounds healed by first intention. No internal or external fistula complications occurred. All incisions at the recipient site healed by first intention. All patients were followed up 12-18 months (mean, 14 months). There was no obvious abnormality in the color and texture of the flap, the oral and facial appearances were symmetrical, and there was no obvious swelling in the cheek. At last follow-up, the patient's mouth opening was (2.89±0.33) cm, which was not significantly different from that before operation ( t=1.879, P=0.087). The subjective satisfaction scores of 12 patients were 6-8 points, with an average of 7.3 points. Significant scars remained at the donor site but concealed in location. Conclusion The folded transverse superficial epigastric artery perforator flap can be used as a surgical method for repairing large penetrating defects after the buccal carcinoma resection, with a good recovery of facial appearance and oral function.

Abstract
Objective To compare the effectiveness of unilateral biportal endoscopy (UBE) technique with the interlaminar uniportal endoscopy (IUE) technique for the treatment of L 5, S 1 lumbar disc herniation. Methods The clinical data of 69 patients with L 5, S 1 lumbar disc herniation who met the selection criteria between January 2020 and December 2020 were retrospectively analysed. The patients were divided into UBE group (30 cases) and IUE group (39 cases) according to endoscopic surgical technique. The general data, such as gender, age, body mass index, disease duration, and preoperative visual analogue scale (VAS) scores of low back/leg pain and Oswestry disability index (ODI), was not significantly different between the two groups ( P>0.05). Perioperative outcomes [estimated blood loss (EBL), total operation time, extracanal operation time, intracanal decompression time, intraoperative radiation exposure dose, incision length, operative related complications, and postoperative hospitalization stay] and clinical outcomes (VAS score of low back/leg pain before operation and at 3 days, 3 months, 6 months, and 12 months after operation as well as the ODI before operation and at 3 months, 6 months, and 12 months after operation) were recorded and compared between the two groups. Results All patients completed the surgery successfully. The incision length, EBL, and extracanal operation time in UBE group were significantly longer than those in IUE group ( P<0.05), and the intracanal decompression time in UBE group was significantly shorter than that in IUE group ( P<0.05). There was no significant difference in the total operation time, intraoperative radiation exposure dose, and postoperative hospitalization stay between the two groups ( P>0.05). Patients in both groups were followed up 12-15 months (mean, 13.3 months). Dural tear ocurred in 1 patient of the UBE group, and recurrence ocurred in 1 patient of the IUE group, the others of both groups had no surgery-related complications and recovered well after operation. The VAS scores of low back/leg pain and ODI in both groups at each time point after operation significantly improved when compared with those before operation ( P<0.05); there was no significant difference in VAS scores and ODI at each time point after operation between two groups ( P>0.05). Conclusion The effectiveness of UBE technique in the treatment of L 5, S 1 lumbar disc herniation is similar to that of IUE technique, and the efficiency of intraspinal operation is better than that of IUE technique. Although UBE technique is inferior to IUE technique in terms of surgical trauma, there is no significant difference in postoperative recovery between the two techniques.

Abstract
OBJECTIVE To evaluate the clinical characteristics and effectiveness of pulpotomy in mature permanent teeth with bioceramic putty repairmen iRoot and mineral trioxide aggregate (MTA). METHODS Pulpotomy was performed on mature permanent premolars and molars with carious exposures at the Department of General Dentistry of Peking University School and Hospital of Stomatology, from November 2017 to September 2019. The patients were randomly divided into 2 groups, Group iRoot (n=22) and Group MTA (n=21). In Group iRoot, bioceramic putty repairmen iRoot was used as pulp capping agent, while in Group MTA, mineral trioxide aggregate was used as pulp capping agent. All the patients had signed informed consent forms. The clinical efficacy was evaluated by clinical examinations (temperature and electrical activity test) and imaging examinations 3, 6, and 12 months after surgery. Blinding was used for the patients and evaluators, but due to the obvious differences in the properties of the two pulp capping agents, the blinding method was not used for the treatment provider (the attending physician). RESULTS There was no significant difference in gender, average age, dentition and tooth position distribution between the two groups (P>0.05). In the study, 7 cases were lost to follow-up 12 months after operation (4 cases in Group iRoot, and 3 cases in Group MTA). One case in each of the two groups had transient sensitivity at the end of the 3-month follow-up, and the pulp vitality was normal at the end of the 6-month follow-up. One case in Group iRoot showed sensitivity at the end of the 12-month follow-up. The success rates of the two groups at the end of 12-month follow-up were 100%, and the cure rates were 94.4% (Group iRoot) and 100% (Group MTA), respectively, and the difference was not statistically significant (P>0.05). No cases in Group iRoot had obvious crown discoloration, while 3 cases in Group MTA had. CONCLUSION The clinical characteristics and effectiveness of pulpotomy in mature permanent teeth with bioceramic putty repairmen iRoot were similar with MTA. Bioceramic putty repairmen iRoot is an acceptable material when used in pulpotomy of mature permanent teeth. Because it is not easy to cause tooth discoloration after treatment and is convenient to operate, bioceramic putty repairmen iRoot has a better clinical application prospect.

Abstract
OBJECTIVE To investigate the associations of impaired glucose metabolism and insulin resistance with chronic periodontitis in pre-diabetes patients. METHODS A cross-sectional analysis was conducted and we included a total of 171 pre-diabetes patients aged 30-65 years, free of diabetes. pre-diabetes was defined as impaired fasting glucose (IFG) [fasting glucose (FG): 6.1-7.0 mmol/L] and/or impaired glucose tolerance (IGT) [oral glucose tolerance test (OGTT): 7.8-11.0 mmol/L]. Chronic periodontitis was defined according to Centers for Disease Control and Prevention (CDC)/American Academy of Periodontology (AAP) definition and the patients were divided into mild, moderate, and severe chronic periodontitis groups [mild: at least two interproximal sites with clinical attachment loss (CAL) ≥3 mm and at least two interproxima sites with probing depth (PD) ≥4 mm or 1 site with PD≥5 mm; moderate: at least two interproximal sites with CAL ≥4 mm and at least two interproxima sites with at least two interproximal sites with PD ≥5 mm; severe: at least two interproximal sites with CAL ≥6 mm and at least one interproxima site with at least two interproximal sites with PD≥5 mm]. A periodontal examination indexes [plaque index (PLI), PD, CAL, and bleeding on probing (BOP)] and glucose metabolism indexes [FG, OGTT, hemoglobinA1c (HbA1c), fasting insulin and homeostasis model assessments of insulin resistance (HOMA-IR)] were measured. The association of glucose metabolism and chronic periodontitis was investigated by multivariable logistic regression analysis. RESULTS FG in the moderate and severe chronic periodontitis groups was significantly higher compared with mild chronic periodontitis group, HOMA-IR in the moderate and severe chronic periodontitis groups was significantly higher compared with mild chronic periodontitis group, OGTT in the severe chronic periodntitis group was significantly higher compared with mild chronic peridontitis group and moderate chronic periodontitis groups, and there was no significant difference between moderate and mild chronic periodontitis groups. For the insulin and HbA1c, there was no significant difference among mild, moderate and severe chronic periodontitis groups. After multivariable adjustment of age, gender, smoking status, hypertension and body mass index, IFG (OR=1.39, 95%CI: 1.01-1.98) and HOMA-IR (OR=1.36, 95%CI: 1.04-1.76) were associated with moderate periodontitis; IFG (OR=1.64, 95%CI: 1.17-2.40), IGT (OR=1.65, 95%CI: 1.21-2.26), and HOMA-IR (OR=1.72, 95%CI: 1.23-2.41) were significantly associated with severe periodontitis. CONCLUSION Our data provided evidences that impaired glucose metabolism were associated with chronic periodontitis among pre-diabetes patients.

Abstract
OBJECTIVE To investigate quinalizarin-induced apoptosis in gastric cancer cells in vitro and explore the molecular mechanisms. METHODS MTT assay was used to determine the cytotoxic effects of quinalizarin on human gastric cancer AGS, MKN-28 and MKN-45 cells. Annexin V-FITC/PI staining and flow cytometry were used to assess quinalizarin-induced apoptosis in AGS cells and its effect on intracellular ROS levels; the expression levels of apoptotic proteins in the cells were determined with Western blotting. RESULTS Quinalizarin dose-dependently reduced the cell viabilities of the 3 gastric cancer cells (P<0.05). The IC50 values of quinalizarin in AGS, MKN-28 and MKN-45 cells were 7.07 µmol/L, 22.55 µmol/L and 14.18 µmol/L, respectively. Quinalizarin time-dependently induced apoptosis of AGS cells and potentiated the generation of intracellular reactive oxygen species (ROS) levels. Pretreatment with NAC, a scavenger of ROS, inhibited quinalizarin-induced apoptosis (P<0.001). Western blotting results showed that quinalizarin also up-regulated the expression levels of the apoptotic proteins including p-p38, p-JNK, Bad, cleaved caspase-3, and cleaved PARP-1 (P<0.05), and down-regulated the expression of the anti-apoptotic proteins p-Akt, p-ERK, and Bcl-2 (P<0.05). CONCLUSION Quinalizarin inhibits the proliferation and induces apoptosis in gastric cancer cells in vitro through regulating intracellular ROS levels via the MAPK and Akt signaling pathways.
