From August 2019 to July 2024, the Institute of Chest Wall Surgery at the Affiliated Guangdong Second Provincial General Hospital of Jinan University admitted multiple patients with severe thoracic deformities. Authors summarized the characteristics and treatment measures of three cases with typical acute-angled thoracic deformities. Three patients aged from 15 to 21 year-old were suffered from severe pectus excavatum, pectus carinatum, and complex thoracic deformities, respectively. Visually, the local bones were severely distorted, and CT scans showed that the local bones formed acute-angled intersections. Three patients underwent Wung surgery, Wenlin surgery, and Wang+ Wenlin surgery. During the operation, based on pre-shaping, the principle of template shaping was applied to implement correction, and the process was uneventful. All deformities were satisfactorily corrected. There were no postoperative complications such as bleeding, pneumothorax, or poor wound healing during 8 months to 4 years of follow-up. Acute angle deformity is a special type of thoracic deformity, and its occurrence often indicates that the local deformity is severe and complex. Therefore, in treatment, surgeons are required to first understand the basic principle of thoracic deformity correction, have a strong comprehension of the overall deformity, and be skillful and experienced in applying various thoracic deformity correction techniques.

OBJECTIVE: To explore the clinical features of patients with necrotizing soft tissue infection (NSTI) and the related factors for sepsis, so as to provide a basis for early intervention and improvement of patients' prognosis. METHODS: A retrospective case series study was conducted to analyze the clinical data of NSTI patients admitted to the department of burns and wound repair surgery of Guangdong Provincial People's Hospital from October 2021 to December 2024. Demographic information, underlying diseases, infection characteristics, laboratory test results and etiological findings at admission, treatment status, occurrence of complications (including sepsis) and prognosis were collected. Univariate and multivariate Logistic regression analyses were used to identify the associated factors for sepsis in NSTI patients. Receiver operator characteristic curves (ROC curves) were plotted to evaluate the predictive value of individual and combined factors for sepsis. RESULTS: A total of 159 NSTI patients were enrolled, mainly middle-aged and elderly males. Most patients had comorbidities, including diabetes mellitus (110 cases, 69.2%) and hypertension (67 cases, 42.1%). The main infection site was the lower extremities (104 cases, 65.4%). Common symptoms included redness (96 cases, 60.4%), swelling (129 cases, 81.1%), local heat (60 cases, 37.7%), pain (100 cases, 62.9%), and skin ulceration or necrosis (9 cases, 5.7%). Imaging findings included soft tissue swelling (66 cases, 57.9%), gas accumulation (41 cases, 36.0%), and abnormal signal/density shadows (50 cases, 43.9%). Staphylococcus aureus was the main pathogenic bacterium [12.0% (31/259)], and drug-resistant Escherichia coli had the highest detection rate among drug-resistant bacteria [35.1% (13/37)]. Regarding debridement and repair, most patients (80 cases, 50.3%) underwent debridement ≥ 72 hours after admission, while only 10.1% (16 cases) received debridement within 6 hours. Most patients underwent multiple debridements, with 2 times of debridements being the most common (68 cases, 42.8%), and the maximum times of debridements reached 6. The largest number of patients received secondary suture (44 cases, 27.7%). In terms of complications, sepsis was the most common (66 cases, 41.51%), followed by acute kidney injury, respiratory failure requiring mechanical ventilation, and multiple organ dysfunction syndrome (MODS), while disseminated intravascular coagulation (DIC) was the least common. During the follow-up period, 9 patients (5.66%) were readmitted within 90 days, and 11 patients died, with a mortality rate of 6.92%. Univariate analysis showed that diabetes, coronary heart disease, gout, body temperature, heart rate, C-reactive protein, platelet count, total bilirubin, albumin, creatinine, out-of-hospital treatment, and out-of-hospital use of antimicrobial agents were significantly associated with sepsis in NSTI patients (all P < 0.05). Multivariate Logistic regression analysis showed that coronary heart disease [odds ratio (OR) = 30.085, 95% confidence interval (95%CI) was 2.105-956.935], C-reactive protein (OR = 1.026, 95%CI was 1.009-1.054), and total bilirubin (OR = 1.436, 95%CI was 1.188-1.948) were independent associated factors for sepsis in NSTI patients (all P < 0.05). ROC curve analysis revealed that the combination of the three predictors yielded the highest AUC for predicting sepsis in NSTI patients compared to any individual predictor [area under the curve (AUC) = 0.799 (95%CI was 0.721-0.878)]. CONCLUSIONS The clinical features of NSTI patients show certain regularity. Coronary heart disease, C-reactive protein, and total bilirubin are independent associated factors for sepsis in NSTI patients.

Objective:To investigate the impact of high-density lipoprotein (HDL) subfraction cholesterol, measured by the vertical auto profile (VAP) technique based on vertical density gradient ultracentrifugation, on the occurrence and progression of coronary heart disease.Methods:This retrospective case-control study consecutively enrolled 94 inpatients diagnosed with coronary artery disease (CAD) by percutaneous coronary angiography at Ningbo University Affiliated First Hospital between June 2023 and June 2024 (CAD group), and 48 outpatients from the cardiology department without carotid or coronary atherosclerosis(non-CAD group). The VAP technique was employed to measure HDL subfraction cholesterol levels (HDL 3-C and HDL 2-C) and their subtypes (HDL 2a-C, HDL 2b-C, HDL 2c-C; HDL 3a-C, HDL 3b-C, HDL 3c-C, HDL 3d-C). Logistic regression analysis was performed to assess the association between HDL subfraction composition and CAD. CAD patients were further stratified by the number of affected coronary vessels (left anterior descending artery, left circumflex artery, and right coronary artery): 44 with single-vessel disease, 22 with double-vessel disease, and 28 with triple-vessel disease for correlation analysis. All CAD patients underwent 6-month clinical and telephone follow-up to record major adverse cardiovascular events (MACE), including acute myocardial infarction, stroke, and repeat revascularization. Using the median HDL 3d-C level (0.064 mmol/L) as cutoff, CAD patients were divided into high-level ( n=48) and low-level ( n=46) subgroups for Kaplan-Meier survival analysis with log-rank testing. Results:Compared with non-CAD controls, CAD patients showed significantly higher HDL 3d-C [0.064 (0.041, 0.095) mmol/L vs 0.055 (0.038, 0.067) mmol/L] and HDL 3b-C [0.031 (0.001, 0.054) mmol/L vs 0.007 (0.004, 0.029) mmol/L], lower HDL 3c-C (0.220±0.080 mmol/L vs 0.254±0.062 mmol/L) and HDL 3a-C [0.282 (0.224, 0.351) mmol/L vs 0.334 (0.269, 0.433) mmol/L] (all P<0.05). Logistic regression revealed that HDL2b-C was a protective factor against atherosclerosis severity ( OR=0.914, 95% CI 0.896-0.987, P<0.001); HDL 3d-C served as both a CAD risk factor ( OR=2.303,95% CI 1.740-3.047, P<0.001) and disease progression indicator ( OR=1.224, 95% CI 1.123-1.335, P=0.025). MACE patients ( n=6) had elevated HDL3d-C versus non-MACE cases ( n=88) [0.120 (0.083, 0.173) mmol/L vs 0.061 (0.037, 0.092) mmol/L, P<0.05]. The high HDL 3d-C subgroup demonstrated significantly lower 6-month survival (χ2=4.777, P=0.029). Conclusion:Contrary to conventional understanding, our study reveals that HDL2b serves as a protective factor against coronary artery disease progression, whereas HDL 3d-C acts not only as a pathogenic factor for CAD but also as a critical determinant of CAD-related adverse events.

Objective::There is limited evidence regarding the choice of P2Y 12 receptor inhibitors as a component of dual antiplatelet therapy in patients with left main (LM) disease undergoing percutaneous coronary intervention (PCI). This study aimed to evaluate long-term clinical outcomes of ticagrelor- vs. clopidogrel-based dual antiplatelet therapy strategy in acute coronary syndrome (ACS) patients undergoing LM PCI. Methods::This is a post-hoc analysis from a prospective, single-center, real-world PCI registry. A total of 1,163 patients discharged post-ACS who underwent LM PCI and received ticagrelor or clopidogrel between March 2016 and March 2019 were included in the study. The primary endpoint was ischemic events at 12 months, including cardiac death, myocardial infarction, or stroke. Secondary outcomes included all-cause death and Bleeding Academic Research Consortium types 2, 3, and 5, and types 3 and 5 bleeding. Propensity score matching was used to adjust for bias due to confounders between the 2 groups.Results::The ticagrelor and clopidogrel groups comprised 529 (45.49%) and 634 (54.51%) patients, respectively. During the follow-up period, the rate of ischemic events was significantly lower with ticagrelor than with clopidogrel before (1.32% (7/529) vs. 3.63% (23/634), P = 0.013,6) and after propensity score matching (1.41% (6/425) vs. 4.00% (17/425), P = 0.020,1). The rates of all-cause death, Bleeding Academic Research Consortium-defined type 2, 3, and 5 bleeding, and type 3 and 5 bleeding were similar between the ticagrelor group and clopidogrel group before or after propensity score matching adjustment (all P > 0.05). Conclusion::Among patients with ACS undergoing LM PCI, ticagrelor use was associated with ischemic events benefit without excessive risk of bleeding at 12 months compared with clopidogrel.

Replacement of the temporomandibular joint (RTJ) has undergone decades of technological improvements and is now an important treatment for end-stage temporomandibular joint (TMJ) disease. The main complications of RTJ include aseptic loosening, heterotopic ossification, postsurgical infection, hypersensitivity reaction, prosthesis loosening or malposition, nerve injury and severe bleeding. Improvement in clinical technique is now the key to resolving complications. In the future, improvements in prosthetic materials may be an important development for newer iterations. With the development and popularity of TMJ surgical techniques, prosthesis-related complications will increasingly come into clinical view. This article provides a systematic review of the complications of RTJ prosthesis replacement and the measures to deal with them, and looks forward to the direction of the development of this field from the perspective of reducing complications, so as to provide a reference for clinical work.

Objective To evaluate the efficacy of XELOX regimen as neoadjuvant chemotherapy in the treatment of stage Ⅱ and Ⅲ colon cancer.Methods The clinical data of 50 patients with clinical stage Ⅱ(T4)Ⅲ colon cancer who underwent laparoscopic radical resection at general surgery department of our hospital from January 1,2012 to January 1,2021 were retrospectively analyzed.Patients were divided into neoadjuvant chemotherapy group(NACT)and adjuvant chemotherapy group(ACT)according to whether they received neoadjuvant chemotherapy with XELOX regimen.The general clinical data,adverse reactions of chemotherapy,surgical complications,operation time,intraoperative blood loss,hospitalization time,hospitalization cost,negative conversion rate of tumor markers,tumor remission rate,tumor downstaging rate,tumor response grade after chemotherapy,postoperative disease-free survival curve,and overall survival curve were retrospectively analyzed and compared among the groups.Results There were no significant differences in operative complications,postoperative exhaust time and hospital stay between NACT group and ACT group(P＞0.05).The adverse reactions of chemotherapy,the negative conversion rate of postoperative CEA and CA19-9,the duration of operation,the amount of bleeding,and the hospitalization cost in NACT group were significantly better than those in ACT group(P＜0.05).In terms of DFS and OS survival curves,with the extension of time,the decline of the NACT survival curve was smaller than that of the ACT group,and there was a significant difference in DFS survival curve(P＜0.05),but no significant difference in OS survival curve(P＞0.05).Conclusion XELOX neoadjuvant chemotherapy is safe and effective in the treatment of stage Ⅱ(T4)and stage Ⅲcolon cancer.

Objective To explore the predictive value of the expression of serum forkhead box protein M1(FOXM1)and insulin-like growth factor 2(IGF2)on the prognosis of elderly patients with heart failure complicated with pneumonia.Methods A total of 126 elderly patients with heart failure complicated with pneumonia admitted to Handan Central Hospital from March 2021 to June 2022 were included in case group.According to the follow-up results,the 122 patients were grouped into poor prognosis group(n=33)and good prognosis group(n=89).Meanwhile,126 healthy people in the same period were included as the control group.The levels of serum FOXM1 and IGF2,forced vital capacity(FVC)and forced expiratory volume in the first second(FEV1)in the two groups(case group and control group)were measured.Spearman method was used to analyze the correlation between serum levels of FOXM1 and IGF2 and heart function classification in elderly patients with heart failure complicated with pneumonia.The predictive value of serum FOXM1 and IGF2 levels in elderly patients with heart failure complicated with pneumonia was analyzed by receiver operating characteristic(ROC)curve.Results Compared with the control group,the levels of FOXM1(2.39±0.55 vs 1.06±0.21)and IGF2(71.33±7.96pg/ml vs 47.82±5.14pg/ml)in the case group were significantly higher(t=25.358,27.581,all P<0.05).Compared with the good prognosis group,the levels of serum FOXM1(3.87±1.06 vs 1.95±0.51)and IGF2(85.88±9.54pg/ml vs 69.14±8.73pg/ml)in the poor prognosis group were significantly higher,and the differences were statistically significant(t=13.453,9.174,all P<0.05).There were significant differences in heart function classification between the good prognosis group and the poor prognosis group,and the differences were statistically significant(χ2=7.120,P<0.05).Compared with the poor prognosis group,FEV1(1.24±0.32 L vs 1.08±0.25 L)and FEV1/FVC(55.46%±5.77%vs 52.30%±5.38%)in good prognosis group were significantly higher,and the differences were statistically significant(t=2.592,2.735,all P<0.05).The levels of serum FOXM1 and IGF2(r=0.496,0.517,all P<0.05)in elderly patients with heart failure complicated with pneumonia were positively correlated with heart function classification.ROC curve results showed that the area under the curve(AUC)of serum FOXM1 alone in predicting the prognosis of elderly patients with heart failure complicated with pneumonia was 0.854(95CI%:0.779～0.912),with sensitivity and specificity of 75.76%and 86.52%,respectively,and the optimal cut-off value of 2.75.The AUC of IGF2 alone in predicting the prognosis of elderly patients with heart failure complicated with pneumonia was 0.874(95CI%:0.802～0.927),with sensitivity and specificity of 72.73%and 85.39%,respectively,and the optimal cut-off value of 78.30 pg/ml.The AUC of the combination of the two in predicting the prognosis of elderly patients with heart failure complicated with pneumonia was greater than the AUC diagnosed by serum FOXM1 alone and IGF2 alone(Z=2.737,2.413,P=0.006,0.016).Conclusion The serum levels of FOXM1 and IGF2 were increased in elderly patients with heart failure complicated with pneumonia,indicating the combined detection of the two may have a high predictive value for the prognosis of patients.
