OBJECTIVEThis study aims to analyze the biomechanical effects of four sutures that are related to maxillary growth during a maxillary protraction treatment cycle based on labiolingual appliance.
METHODSA three-dimensional simulation of labiolingual appliance was performed based on a three-dimensional finite-element maxillofacial model combined with solid-modeled sutures.
RESULTSThe displacement and stress distributions were calculated. The labiolingual appliance was suitable for patients with underbites or deep overbites. Sutura frontomaxillaris and sutura zygomaticomaxillaris were vital to the forward displacement and counterclockwise rotation of the maxillary. The changes in sutura zygomaticotemporalis and sutura palatine were not significant.
CONCLUSIONThe influences of the labiolingual appliance on the sutures during the treatment cycle of maxillary protraction can be effectively simulated by the three-dimensional finite-element maxillofacial model.

Objective:To explore the relationship between the expression of tumor necrosis factor receptor-associated factor 5 (TRAF5) and interferon regulatory factor 5 (IRF5) in intestinal mucosa of patients with ulcerative colitis and gut microbiota and intestinal mucosal barrier function.Methods:A total of 126 patients with ulcerative colitis in Qingdao Municipal Hospital from April 2021 to April 2023 were collected, according to the condition, there were 76 patients in the active phase and 50 patients in the remission phase, another 50 patients with intestinal polyps were taken as controls, intestinal mucosal tissues were collected from patients in three groups. Immunohistochemical staining was applied to detect the expression of TRAF5 and IRF5, the relationship between the expression of TRAF5 and IRF5 in intestinal mucosa of patients with ulcerative colitis and clinical symptoms, gut microbiota, and intestinal barrier function indicators was analyzed. Spearman method was applied for correlation analysis.Results:The positive expression rates of TRAF5 and IRF5 in intestinal mucosa of patients with active phase and remission phase ulcerative colitis were higher than those of patients with intestinal polyps: 85.53% (65/76) and 80.00% (40/50) vs. 40.00% (20/50), 81.58% (62/76) and 76.00% (38/50) vs. 50.00% (25/50), and the difference was statistically significant ( P<0.05); the expression of TRAF5 and IRF5 in intestinal mucosa of patients with ulcerative colitis was related to diarrhea, abdominal pain, purulent stool, tumor necrosis factor-α (TNF-α), Interleukin-6 (IL-6), C-reactive protein (CRP), erythrocyte sedimentation rate, Baron endoscopic score, inflammatory bowel disease questionnaire score, Mayo index score and Geboes index ( P<0.05). Compared with patients with negative expression of TRAF5 and IRF5, patients with positive expression of TRAF5 and IRF5 had fewer bifidobacteria and lactobacilli, and more enterobacteria and enterococcus: (8.72 ± 0.43) cfu/g vs. (6.85 ± 0.47) cfu/g, (9.74 ± 0.31) cfu/g vs. (8.26 ± 0.27) cfu/g, (9.73 ± 0.46) cfu/g vs. (11.06 ± 0.48) cfu/g, (7.64 ± 0.31) cfu/g vs. (8.47 ± 0.34) cfu/g; (8.82 ± 0.44) cfu/g vs. (6.73 ± 0.47) cfu/g, (9.13 ± 0.30) cfu/g vs. (8.22 ± 0.27) cfu/g, (11.09 ± 0.48) cfu/g vs. (9.87 ± 0.46) cfu/g, (7.76 ± 0.32) cfu/g vs. (8.48 ± 0.34) cfu/g, and the difference was statistically significant ( P<0.05). The levels of diamine oxidase, lipopolysaccharide and D-lactic acid in patients with positive expression of TRAF5 and IRF5 were obviously higher than those in patients with negative expression of TRAF5 and IRF5: (12.18 ± 2.75) mg/L vs. (7.56 ± 2.49) mg/L, (76.14 ± 13.86) ng/L vs. (37.57 ± 12.51) ng/L, (18.15 ± 4.83) U/L vs. (9.87 ± 3.25) U/L; (12.39 ± 2.72) mg/L vs. (7.65 ± 2.66) mg/L, (77.21 ± 13.79) ng/L vs. (40.87 ± 13.04) ng/L, (18.36 ± 4.75) U/L vs. (10.67 ± 3.86)U/L, and the difference was statistically significant ( P<0.05). The expression of TRAF5 in the intestinal mucosa of patients with ulcerative colitis was negatively correlated with the numbers of bifidobacteria and lactobacilli ( r = - 0.645 and - 0.646; P<0.05), and positively correlated with the number of enterobacteria, number of enterococcus, diamine oxidase, lipopolysaccharide and D-lactic acid ( r = 0.629, 0.589, 0.509, 0.606 and 0.596; P<0.05). The expression of IRF5 was negatively correlated with the numbers of bifidobacteria and lactobacilli ( r = - 0.701 and - 0.690; P<0.05), and positively correlated with the number of enterobacteria, number of enterococcus, diamine oxidase, lipopolysaccharide and D-lactic acid ( r = 0.690, 0.624, 0.605, 0.595 and 0.568; P<0.05). Conclusions:The positive rates of TRAF5 and IRF5 in intestinal mucosa of patients with ulcerative colitis is high, which is closely related to the imbalance of gut microbiota and the damage of intestinal mucosal barrier function.

Objective:To study the prognostic risk factors of Enterobacteriaceae bloodstream infection in patients with sepsis.Methods:The medical records of patients with sepsis caused by Enterobacteriaceae bloodstream infection in our hospital from June 2017 to May 2019 were screened. The gender, age, admission department, basic disease, infection site, etiology examination and treatment plan were recorded in detail. The survival and death groups were divided according to the patient's survival status. The ratio of C-reactive protein (CRP) to serum prealbumin (PA) was recorded within 24 h after admission. The acute physiological and chronic health scores (APACHEⅡ score) and Pitt bacteremia score (PBS score) were calculated within 24 h, and based on the results of blood culture drug sensitivity test to analyze whether the initial experience treatment was appropriate. Logistic regression analysis was used to analyze the risk factors affecting the prognosis of patients, and the receiver operating characteristic curve (ROC curve) was drawn to predict the occurrence of poor prognosis in patients with sepsis.Results:Logistic regression analysis showed that CRP ( OR=1.021, P<0.01), CRP/PA ( OR=34.638, P<0.01), extended-spectrum β-lactamase production ( OR=0.244, P<0.01), inappropriate empirical antibacterial treatment ( OR=0.156, P<0.01), APACHE Ⅱ score ( OR=1.436, P<0.01), and PBS score ( OR=8.622, P<0.01) were risk factors affecting patient's prognosis. Multivariate regression analysis showed that CRP/PA ( OR=25.420, P<0.05), inappropriate empirical treatment ( OR=0.077, P<0.05), APACHEⅡ score ( OR=1.476, P<0.01), PBS score ( OR=12.042, P<0.01) were independent risk factors for death in patients with sepsis ( P<0.05). The higher the CRP/PA level, PBS score and APACHEⅡ score, the worse the prognosis. When CRP/PA ≥0.89, PBS score ≥3.5, APACHEⅡ score ≥17.5, the patient's risk of death increased significantly. In addition, inappropriate empirical treatment was also a key factor in patients with poor prognosis. Conclusions:CRP/PA, PBS score, APACHE Ⅱ score, and inappropriate empiricaltreatment are independent risk factors affecting the prognosis of patients with enterobacter hemorrhagic infection with sepsis. The PBS score and APACHEⅡ score can better predict the poor prognosis and risk of death. Compared with APACHEⅡscore, the former is simpler and practical and can be widely used.

Background:The prognostic values of staging parameters require continual re?assessment amid changes in diag?nostic and therapeutic methods. This study aimed to identify the prognostic factors and failure patterns of non?meta?static nasopharyngeal carcinoma (NPC) in the intensity?modulated radiotherapy (IMRT) era. Methods:We reviewed the data from 749 patients with newly diagnosed, biopsy?proven, non?metastatic NPC in our cancer center (South China, an NPC endemic area) between January 2003 and December 2007. All patients under?went magnetic resonance imaging (MRI) before receiving IMRT. The actuarial survival rates were estimated using the Kaplan–Meier method, and survival curves were compared using the log?rank test. Multivariate analyses with the Cox proportional hazards model were used to test for the independent prognostic factors by backward eliminating insigniifcant explanatory variables. Results:The 5?year occurrence rates of local failure, regional failure, locoregional failure, and distant failure were 5.4, 3.0, 7.4, and 17.4%, respectively. The 5?year survival rates were as follows: local relapse?free survival, 94.6%; nodal relapse?free survival, 97.0%; distant metastasis?free survival, 82.6%; disease?free survival, 75.1%; and overall survival, 82.0%. Multivariate Cox regression analysis revealed that orbit involvement was the only signiifcant prognostic fac?tor for local failure (P=0.011). Parapharyngeal tumor extension, retropharyngeal lymph node involvement, and the laterality, longest diameter, and Ho’s location of the cervical lymph nodes were signiifcant prognostic factors for both distant failure and disease failure (allP<0.05). Intracranial extension had signiifcant prognostic value for distant failure (P=0.040). Conclusions:The key failure pattern for NPC was distant metastasis in the IMRT era. With changes in diagnostic and therapeutic technologies as well as treatment modalities, the signiifcant prognostic parameters for local control have also been altered substantially.

Objective:To explore the clinical effect of dual triangular skin flaps for male nipple reconstruction.Methods:From October 2011 to March 2019, we admitted 4 male patients with flat or missing nipples, aged 29 to 45 years old, with an average of 37 years old in Jiangxi Provincial People’s Hospital. Among them, there was 1 case of congenital bilateral flat nipples, 1 case of bilateral nipple loss caused by drug corrosion, and 2 cases of exogenous injury with failure history of bilateral nipple reconstruction. According to the blood supply and elasticity of the skin of the nipple and areola, dual triangular flaps were designed for bilateral nipple reconstruction. The survival of the skin flap was observed and the sensation and shape of the nipple were followed up.Results:Among the 4 patients with 8 nipples, 7 nipples were fully survived symmetrically with no skin flap infection and necrosis. One nipple had local flap necrosis, resulted in wide and flat nipple appearance. During the 12-month follow-up, the reconstructed nipples were soft and felt good. The height of the nipple was 3-4 mm, the diameter was about 5 mm, 7 nipples were in good shape, 1 nipple was slightly small.Conclusions:Dual triangular skin flaps is a good choice for male nipple reconstruction with satisfactory symmetrical appearance and less complication.
