Objective: To investigate the association between monocyte to high-density lipoprotein cholesterol ratio (MHR) and periodontitis and to provide new epidemiologic evidence on the factors affecting periodontitis. Methods: Data on MHR, periodontitis, and other covariates were selected from the NHANES(National Health and Nutrition Examination) database for 3 cycles of subjects in 2009-2010, 2011-2012, and 2013-2014, and a total of 8 456 study subjects were included. The study participants were grouped according to the prevalence of periodontitis (presence or absence), and three regression models (unadjusted covariates, partially adjusted covariates, and fully adjusted covariates) were constructed to analyze the relationship between MHR and periodontitis by using a weighted logistic regression method with stepwise adjustment for confounders. MHR was divided into four groups from Q1 to Q4 according to quartiles from small to large for weighted trend analysis, and the nonlinear relationship between MHR (continuous) and periodontitis was analyzed using a restricted cubic spline with subgroup analysis and sensitivity analysis. Results: All three logistic regression models showed a positive association between MHR and periodontitis (OR = 2.92, 95%CI: 2.14-3.99, P<0.001 (not adjusted); OR = 1.97, 95%CI: 1.39-2.78, P<0.001 (partially adjusted); OR = 1.62, 95%CI: 1.10-2.39, P = 0.017 (fully adjusted)). Trend analysis showed a significantly higher risk of developing periodontitis in the Q4 group compared with the Q1 group in both single (OR = 1.92, 95% CI: 1.58-2.33, P<0.001) and multifactorial analyses (OR = 1.30, 95% CI: 1.03-1.64, P = 0.029). Restricted cubic spline results did not support a nonlinear relationship between MHR and periodontitis (P for nonlinear>0.05), subgroup analysis showed no significant interaction between the covariates and MHR (P>0.05), and sensitivity analysis also showed a positive correlation between MHR and periodontitis (OR = 1.67, 95%CI: 1.31-2.14, P<0.001). Conclusion MHR is positively associated with the risk of developing periodontitis.

OBJECTIVE: To evaluate the early effectiveness of transosseous suture fixation in treating recurrent acute patellar dislocation with patellar osteochondral fractures (OCFs). METHODS: A retrospective analysis was conducted on 19 patients with recurrent acute patellar dislocation and patellar OCFs, who underwent transosseous suture fixation between January 2018 and December 2022 and were followed up 2 years. The cohort included 8 males and 11 females, aged 13-21 years (mean, 16.2 years). Patients experienced 2-5 times of patellar dislocation (mean, 3.2 times). The interval from the last dislocation to operation ranged from 3 to 15 days (mean, 9.6 days). Preoperative imaging revealed the intra-articular osteochondral fragments and medial patellofemoral ligament (MPFL) injury. Clinical outcomes were evaluated using the visual analogue scale (VAS) score for pain, the International Knee Documentation Committee (IKDC) score, the Hospital for Special Surgery (HSS) knee score, the Lysholm score, and the Tegner score. Postoperative complications were recorded. During follow-up, the knee X-ray films, CT, and MRI were taken to evaluate fragment healing, displacement, and the morphology and tension of the MPFL reconstruction graft. RESULTS: All incisions healed primarily, and no complication occurred such as infection, joint stiffness, patellofemoral arthritis, or redislocation. Patients were followed up 24-60 months (mean, 43.5 months). At 12 months postoperatively and the last follow-up, significant improvements ( P<0.05) were observed in VAS, Lysholm, IKDC, HSS, and Tegner scores compared to preoperative values. Further improvements were observed at last follow-up compared with the 12 months postoperatively, and the differences were significant ( P<0.05). Imaging studies demonstrated satisfactory osteochondral fragment positioning with stable fixation. At last follow-up, all fragments had healed, and MPFL reconstruction grafts exhibited optimal morphology and tension. No joint adhesion or fragment displacement occurred. CONCLUSION For recurrent acute patellar dislocation with patellar OCFs, transosseous suture fixation proves to be both safe and effective, achieving satisfactory early effectiveness.

Skeletal class Ⅱ malocclusion is characterized by maxillary protrusion,mandibular retrognathia,or a combination of both,and often accompanied by vertical dimensional discrepancies;treatment is complex,and combined orthodontic-orthognathic surgery is needed for the adult patients.Clear aligner therapy has gradually been applied in complex orthodontic cases.However,limited cases have been reported domestically and internationally regarding the application of clear aligner therapy combined with orthognathic surgery.This article presented a case of a patient with skeletal class Ⅱ high-angle malocclusion treated with the combined therapy and analyzed the clinical efficacy of the treatment appraoch to provide reference for the clinical practice.Extraction of impacted wisdom teeth 18,28,38,and 48,as well as orthodontic teeth 15,25,34,and 44,was performed in stages before orthodontic treatment.Clear aligner therapy was used for preoperative orthodontics.In sagittal plane,a super-complete class Ⅱ canine and molar relationship and a 13-14 mm overjet of the anterior teeth were established.The maxillary and mandibular arch morphology was matched horizontally.The orthognathic surgery included maxillary LeFort Ⅰ osteotomy,bilateral sagittal split ramus osteotomy(BSSRO)and chinplasty.Fine occlusal adjustment was conducted after operation.After treatment,the skeletal relationship between upper and lower jaw was corrected to normal;subspinale-nasion-supramental angle(ANB)was improved from 12.3° to 4.7°;the patient established the class Ⅰ canine and molar relationship,with normal overjet and overbite;root parallelism was good and there was no obvious root resorption;the facial soft tissue profile was significantly improved,and nasion-subnasale-pogonion angle(N-Sn-Pg)was improved from 143.9° to 162.8°.The curative effect was stable 1 year after operation.Clear aligner therapy can efficiently complete combined orthodontic and orthodontic surgery in the complex cases.Compared with the fixed appliance,it is more beneficial to the patients'need for beauty and the maintenance of periodontal health.

The patients with skeletal Class Ⅱ high-angle malocclusion are frequently complicated by idiopathic condylar resorption(ICR),which may lead to temporomandibular joint(TMJ)dysfunction and dentofacial deformities.This article reports the diagnosis and treatment process of a 24-year-old female patient with skeletal Class Ⅱ high-angle malocclusion accompanied by ICR.The patient's chief complaints were anterior open bite and TMJ pain,and was diagnosed with ICR through clinical examination and imaging.After stabilizing condylar resorption with occlusal splint therapy,combined orthodontic-orthognathic treatment was performed.The 42-month follow-up revealed:well-aligned dentition with complete closure of diastemas,significant improvement of protrusive facial profile(ANB angle reduced by 4.2°),complete resolution of TMJ pain and clicking,and establishment of stable Class Ⅰ occlusion.Three-dimensional CT demonstrated satisfactory condylar bone remodeling and normalized joint space.Through multidisciplinary treatment,both occlusal function and facial aesthetics were significantly improved.This case demonstrates that orthodontic-orthognathic treatment should be performed after condylar stabilization in ICR patients,and occlusal splint therapy serves as an effective preoperative intervention.

ObjectiveTo observe the clinical efficacy and safety of Tengfu Jiangya tablets combined with valsartan/amlodipine in the treatment of grade 2 hypertension with liver Yang hyperactivity syndrome. MethodAccording to a randomized，double-blind，and placebo parallel control method，288 patients with grade 2 hypertension with liver Yang hyperactivity from 7 subcenters were included. They were randomly divided into an observation group （144 cases） and a control group （144 cases），and then treated with Tengfu Jiangya tablets combined with valsartan/amlodipine and placebo combined with valsartan/amlodipine，respectively. The efficacy was evaluated after four weeks of intervention. During the experiment，the safety indicators and adverse reaction events of the subjects were recorded for safety evaluation，and the efficacy indicators and TCM syndrome scores were recorded for effectiveness evaluation. Sensitivity analysis was also conducted on the statistical results of the main efficacy indicators such as blood pressure （BP） compliance rate to ensure the accuracy of the analysis results. 88 groups of blood samples from each of the treatment and control groups were included as test subjects. Fasting blood samples were collected from the patients in the clinical trial on the day before and after medication，and enzyme linked immunosorbent assay （ELISA） was performed on the treated serum. The levels of arachidonic acid （AA），thromboxane B₂ （TXB₂），and prostaglandin E₂ （PGE₂） in the serum of the patients before and after treatment were measured to explore the regulation of inflammatory factors in the body by Tengfu Jiangya tablets. ResultA total of 271 patients （133 in the observation group and 138 in the control group） completed the trial. There was no statistically significant difference before and after treatment in such safety indicators as the blood routine （white blood cells，red blood cells，and platelets），urine routine （urinary protein and urinary red blood cells），alanine aminotransferase，aspartate aminotransferase，creatinine，urea，and abnormal electrocardiogram，and no serious adverse reactions were observed. After four weeks，the systolic blood pressure （SBP） difference and diastolic blood pressure （DBP） difference of patients in the observation group were greater than those in the control group（P<0.01）. According to the criteria for determining the antihypertensive effect，the overall response rate in the observation group［89.47%（119/133）］ was higher than that in the control group［57.97%（80/138）］ （Z=2.593，P<0.01）. The SBP compliance rate was 61.65%（82/133） and 37.68%（52/138） in the observation group and control group， respectively. The DBP compliance rate in the observation group was 78.20%（104/133），while in the control group it was 55.07%（76/138）. The overall BP compliance rate in the observation group was 48.12%（64/133），while in the control group it was 23.19%（32/138）. The BP compliance rates in the observation group were all significantly higher than those in the control group（χ²=15.571，16.236，18.404，P<0.01）. According to the criteria for evaluating the therapeutic effect of TCM syndrome integration，the overall response rate of the observation group［57.89%（77/133）］ was higher than that of the control group［38.41%（53/133）］ （Z=-3.172，P<0.01）.Compared with those before treatment， the levels of serum AA and TXB₂ in the two groups were significantly decreased after treatment （P<0.01）， and the level of PGE₂ in the observation group was significantly increased （P<0.01）. Compared with those of the control group after treatment， the levels of AA and TXB₂ in the observation group were significantly decreased， while the level of PGE₂ was significantly increased （P<0.01）. The results suggest that Tengfu Jiangya tablets can effectively reduce inflammatory factors，reduce the production of inflammatory mediators，and thus prevent the occurrence of inflammatory reactions in the treatment of patients with grade 2 hypertension. ConclusionTengfu Jiangya tablets can more effectively reduce patients' SBP and DBP，improve their BP compliance rates，and improve their TCM syndromes in the treatment of grade 2 hypertension with liver Yang hyperactivity. Its clinical application is safe. Tengfu Jiangya tablets has outstanding clinical efficacy and can be used as an effective intervention method for the treatment of grade 2 hypertension with liver Yang hyperactivity syndrome.

BACKGROUND:Trauma-induced coagulopathy(TIC)due to serious injuries significantly leads to increased mortality and morbidity among elderly patients.However,the risk factors of TIC are not well elucidated.This study aimed to explore the risk factors of TIC in elderly patients who have major trauma. METHODS:In this retrospective study,the risk factors for TIC in elderly trauma patients at a single trauma center were investigated between January 2015 and September 2020.The demographic information including gender,age,trauma parts,injury severity,use of blood products,use of vasopressors,need of emergency surgery,duration of mechanical ventilation,length of stay in the intensive care unit(ICU)and hospital,and clinical outcomes were extracted from electric medical records.Multivariate logistic regression analysis was performed to differentiate risk factors,and the performance of the model was evaluated using receiver operating characteristics(ROC)curves. RESULTS:Among the 371 elderly trauma patients,248(66.8%)were male,with the age of 72.5±6.8 years,median injury severity score(ISS)of 24(IQR:17-29),and Glasgow coma score(GCS)of 14(IQR:7-15).Of these patients,129(34.8%)were diagnosed with TIC,whereas 242(65.2%)were diagnosed with non-TIC.The severity scores such as ISS(25[20-34]vs.21[16-29],P<0.001)and shock index(SI),(0.90±0.66 vs.0.58±0.18,P<0.001)was significantly higher in the TIC group than in the non-TIC group.Serum calcium levels(1.97±0.19 mmol/L vs.2.15±0.16 mmol/L,P<0.001),fibrinogen levels(1.7±0.8 g/L vs.2.8±0.9 g/L,P<0.001),and base excess(BE,-4.9±4.6 mmol/L vs.-1.2±3.1 mmol/L,P<0.001)were significantly lower in the TIC group than in the non-TIC group.Multivariate logistic regression analysis revealed that ISS>16(OR:3.404,95%CI:1.471-7.880;P=0.004),SI>1(OR:5.641,95%CI:1.700-18.719;P=0.005),low BE(OR:0.868,95%CI:0.760-0.991;P=0.037),hypocalcemia(OR:0.060,95%CI:0.009-0.392;P=0.003),and hypofibrinogenemia(OR:0.266,95%CI:0.168-0.419;P<0.001)were independent risk factors for TIC in elderly trauma patients.The AUC of the prediction model included all these risk factors was 0.887(95%CI:0.851-0.923)with a sensitivity and specificity of 83.6%and 82.6%,respectively. CONCLUSION:Higher ISS(more than 16),higher SI(more than 1),acidosis,hypocalcemia,and hypofibrinogenemia emerged as independent risk factors for TIC in elderly trauma patients.
