Objectives:
. The necessity to develop a method for prognostication and to identify novel biomarkers for personalized medicine in patients with head and neck squamous cell carcinoma (HNSCC) cannot be overstated. Recently, pathomics, which relies on quantitative analysis of medical imaging, has come to the forefront. CXCL8, an essential inflammatory cytokine, has been shown to correlate with overall survival (OS). This study examined the relationship between CXCL8 mRNA expression and pathomics features and aimed to explore the biological underpinnings of CXCL8.
Methods:
. Clinical information and transcripts per million mRNA sequencing data were obtained from The Cancer Genome Atlas (TCGA)-HNSCC dataset. We identified correlations between CXCL8 mRNA expression and patient survival rates using a Kaplan-Meier survival curve. A retrospective analysis of 313 samples diagnosed with HNSCC in the TCGA database was conducted. Pathomics features were extracted from hematoxylin and eosin–stained images, and then the minimum redundancy maximum relevance, with recursive feature elimination (mRMR-RFE) method was applied, followed by screening with the logistic regression algorithm.
Results:
. Kaplan-Meier curves indicated that high expression of CXCL8 was significantly associated with decreased OS. The logistic regression pathomics model incorporated 16 radiomics features identified by the mRMR-RFE method in the training set and demonstrated strong performance in the testing set. Calibration plots showed that the probability of high gene expression predicted by the pathomics model was in good agreement with actual observations, suggesting the model’s high clinical applicability.
Conclusion
. The pathomics model of CXCL8 mRNA expression serves as an effective tool for predicting prognosis in patients with HNSCC and can aid in clinical decision-making. Elevated levels of CXCL8 expression may lead to reduced DNA damage and are associated with a pro-inflammatory tumor microenvironment, offering a potential therapeutic target.

Objective:To investigate the clinical efficacy of preoperative three-dimensional (3D) reconstruction planning in total hip arthroplasty for development dysplasia of the hip secondary to osteoarthritis.Methods:A total of 80 patients with osteoarthritis secondary to Crowe I-III developmental dysplasia of the hip who underwent primary unilateral total hip arthroplasty from October 2019 to March 2021 were retrospectively analyzed, including 18 males and 62 females and the mean age was 55.7±10.4 years (range 41-72 years). Forty patients in the 3D group, the prosthesis type and installation angle were planed on the 3D reconstruction software based on the full-length CT scan data of the lower limbs, and the length difference of the lower limbs and hip offset were calculated. Forty patients in the control group underwent preoperative planning using conventional film measurement, and lower limb length was judged based on the preoperative measurement data and intraoperative comparison of both lower limbs. The difference of postoperative leg length, hip offset, hip function score, operating time, intraoperative blood loss, and incidence of complications were compared between the two groups.Results:All 80 patients completed the surgery successfully and the follow-up time was up to 3 months after operation. The 3D group was better than the control group in operation time (70.9±7.7 min vs. 81.6±13.3 min, t=-4.91, P<0.001), the difference of postoperative lower limb length (2.78±1.31 cm vs. 5.35±2.15 cm, t=-5.74, P<0.001), and hip function score at 1 week after operation (75.67±3.35 vs. 67.35±4.21, t=12.33, P=0.002), with statistically significant differences. In the 3D group, 95% of acetabular prosthesis and 90% of femoral stem components were consistent with the planned model, while the rate were only 75% and 68% in the control group, and the difference was statistically significant (χ 2=7.51, P=0.023; χ 2=14.92, P=0.005). There were no intraoperative complications such as vascular and nerve injury, and no postoperative complications such as dislocation or periprosthetic infection in all 80 patients. Conclusion:3D preoperative planning assisted total hip arthroplasty in the treatment of Crowe I-III developmental dysplasia of the hip secondary to osteoarthritis can improve the accuracy of the operation, and has a good clinical effect on restoring the leg length and hip offset.

Objective:To observe the application and clinical effect of stromal vascular fraction gel (SVF-gel) in local rhinoplasty.Methods:A total of 84 patients with mild nasal root and low bridge were divided into observation group and control group. In the observation group, liposuction with SVF gel extraction plus injection rhinoplasty was carried out; in the control group, liposuction plus injection rhinoplasty was carried out according to the height change of nasal root and bridge, the change of nasal frontal angle, the occurrence of complications and the satisfaction of patients after operation.Results:The 84 patients were followed up for 2 weeks to 24 months. The height of nasal root and bridge increased significantly and the lines were more harmonious. The absorption of the observation group was much lower than that of control group. Except 3 patients in the observation group and 8 patients in the control group, there were different degrees of absorption within 6 months after operation. All patients did not have complications such as fat liquefaction, necrosis, induration and infection in the injection area. Three patients in the observation group were satisfied with the results after reinjection, and one patient in the control group was satisfied with the results after reinjection, three patients were not satisfied with the results, and four patients were satisfied with the prosthesis augmentation rhinoplasty. In the observation group, there were 37 cases of excellent satisfaction, 5 cases of good satisfaction, and the overall satisfaction was 100%; in the control group, there were 20 cases of excellent satisfaction, 15 cases of good satisfaction, 7 cases of bad satisfaction, and the satisfaction was 83.3%. The former was better than the latter.Conclusions:In view of superiorities such as lower complications with long-lasting effect, high fat survival rate and high satisfaction in local augmentation rhinoplasty, SVF-gel injection is especially suitable for patients who cannot accept autologous bone, prosthesis and allograft tissue filler for augmentation rhinoplasty.

Objective:To investigate the characteristic of mammography, magnetic resonance imaging (MRI), ultrasonography and pathology of mucinous breast carcinoma (MBC); and to study the differential diagnosis value of the three methods in pure MBC (PMBC) and mixed MBC (MMBC).Methods:One hundred and three lesions in 100 MBC patients confirmed by surgery and pathology in the Affiliated Cancer Hospital of Fudan University from January 2011 to January 2018 were retrospectively analyzed. According to the 2013 version of the breast imaging report and data system (BI-RADS) criteria, the three imaging findings of lesions were described, evaluated and classified. According to pathological results the lesions were divided into two groups, PMBC and MMBC, and their imaging features and differences were analyzed.Results:On mammography, most of the mammary glands were c-types (55/76, 72%), and the lesions were mostly masses (71/76, 93%), most of which were round, oval, high-density masses with circumscribed, microlobulated or indistinct margins. Suspected malignant calcification was showed in 21% (16/76) of these lesions. Eight patients had ipsilateral axillary lymphadenopathy. On MRI, most lesions showed masses (69/72, 96%). Sixty-seven lesions (31/72, 43%; 36/72, 50%) showed equal and high signals on T 1WI, and 54 lesions (54/72, 75%) showed higher signals on T 2WI. The margins were mostly irregular and burrs (53/69, 77%). Masses enhancement was dominated by heterogeneous enhancement (32/69, 46%) and rim enhancement (33/69, 48%). The patter of time-signal intensity was dominated by progressive curves (41/72, 57%) and platform curves (24/72, 33%). The lesions had heterogeneous high signal on DWI. The ADC signal was slightly higher than normal gland. Seven patients were accompanied with thickening of the skin and nipple retraction. Eight patients had ipsilateral axillary lymphadenopathy. One patient had multiple lung metastases. On ultrasonography, most lesions showed irregular masses, heterogeneous hypoechoic, well-defined margins, posterior echo enhancement (75/97, 77%). Color Doppler imaging showed vascularity in 65% (63/97) of these lesions. Nine patients had ipsilateral axillary lymphadenopathy. There was significant difference in margins between PMBC and MMBC ( P < 0.05) on MRI and ultrasonography. It showed significant difference in vascularity between 2 groups ( P < 0.05) on MRI. Conclusions:MBC has some typical features in mammography, MRI and ultrasonography. Realizing its features can improve the diagnostic accuracy of MBC, and it also can contribute to the differential diagnosis of PMBC and MMBC.

OBJECTIVE:
To evaluate the value of digital breast tomosynthesis (DBT) in diagnosis of dense breast lesions.
METHODS:
Clinical and pathological data of 163 patients (58 benign lesions, 122 malignant lesions, and 180 lesions in total) with breast lesions undergoing surgical treatment in Shaoxing Central Hospital from January 2017 to December 2018 were retrospectively analyzed. The lesions were classified into non-homogeneous dense gland type and extremely dense gland type according to BI-RADS creterion. Breast MRI and DBT examinations were performed before the surgery. ROC curve was generated and the diagnostic efficacy of two examination methods for dense breast lesions was evaluated with pathological results as the gold standard. The detection rate, diagnostic accuracy of benign and malignant breast lesions were compared between two methods using chi-square test. The accuracy of lesion size preoperatively evaluated by MRI and DBT was analyzed by Pearson correlation.
RESULTS:
The detection rate and diagnostic accuracy for benign breast lesions by MRI were higher than those by DBT (91.4% vs. 75.9%, =5.098, <0.05 and 89.7% vs. 67.2%, =8.617, <0.01). But there were no significant differences in detection rate and accuracy for malignant lesions by MRI and DBT (98.4% vs. 95.1%, =2.068, >0.05 and 94.3% vs. 91.8%, =0.569, >0.05). The areas under the ROC curves of MRI, DBT based on BI-RADS classification were 0.910 and 0.832, respectively (=1.860, >0.05). The sensitivities of MRI, DBT to breast lesions were 93.3% and 86.7%, and the specificities were 68.3% and 79.1%. DBT and MRI measurements were positively correlated with pathological measurements (=0.887 and 0.949, all <0.01).
CONCLUSIONS
DBT can effectively diagnose benign and malignant breast lesions under dense gland background, and it has similar diagnostic efficacy with MRI for breast malignant lesions.

Objective To assess the value of contrast enhanced mammography (CESM) in the detection of breast cancer. Methods A total of 145 patients who were suspected of breast abnormalities by clinical examination or ultrasound were prospectively collected. All patients underwent bilateral breast CESM and MRI examinations. Breast CESM and MRI examination were completed in the same week. The pathological specimens were analyzed and the maximum diameters of pathological lesions were measured. The lesions were observed on low energy(LE), CESM and MRI images, and then the maximum diameters of lesions on the above images were measured. Using pathology results as the gold standard, the diagnostic efficacy of LE, CESM and MRI were analyzed by ROC curve, and Z test was used to compare the areas under the ROC curves among different imaging methods. Bland-Altman method was used to analyze the consistency of the maximum diameters of the lesions obtained with different imaging methods. Results One hundred and fifty three lesions were found in 145 patients, in which 36 were benign and 117 were malignant. The LE, CESM and MRI showed 140, 151 and 149 lesions respectively, and the qualitative diagnostic errors were 25, 8 and 11, respectively. The areas under ROC curves of LE, CESM and MRI were 0.87, 0.96 and 0.97 respectively. There was significant difference of the area under ROC curve between CESM and LE, so did the MRI and LE (P<0.05), but there was not significant difference between CESM and MRI (P=0.51). The sensitivity, specificity and accuracy in the diagnosis of malignant breast lesions were 88.98%, 65.71% and 83.66% for LE, while they were 95.80%, 91.18% and 94.77% for CESM, 94.17%, 87.88%and 92.81%for MRI. The average difference of diameters between LE, CESM, MRI and pathologic size was-1.7, 1.1 and 0.3 mm, respectively, with 95%consistency interval range of-18.6 to 15.1,-9.8 to 12.1,-10.6 to 11.2 mm, respectively. There was best consistency between the pathological size and the size on MRI. Conclusion CESM can significantly improve the diagnostic efficacy of breast lesions, which is comparable with MRI.

Objective To compare the results of thrombelastography (TEG) and the conventional coagulability test in patients with sepsis, and to discuss the value of TEG in monitoring blood coagulation dysfunction in patients with sepsis. Methods The clinical data of 92 adult patients with sepsis admitted to Department of Critical Care Medicine of the First Affiliated Hospital of Guangxi Medical University were retrospectively analyzed. The patients were divided into sequential organ failure assessment (SOFA) score ≥ 12 group (n = 47) and SOFA < 12 group (n = 45). Thirty-five non-sepsis adult patients with normal coagulation function served as control group. The venous blood was collected for conventional blood coagulation test and routine examination of blood, D-dimer, procalcitonin (PCT), and TEG, and the differences were compared among three groups. Correlations between SOFA and various indexes of patients with sepsis were analyzed by Spearman rank correlation method. Results As shown in the results of the conventional blood coagulation test, D-dimer was gradually increased with the aggravation of the disease, the values in non-sepsis, SOFA < 12, and SOFA ≥ 12 groups were 0.523 (0.273, 0.928), 0.863 (0.673, 4.221), and 4.118 (2.420, 5.653) mg/L respectively (Z = 25.163, P = 0.000). Platelet count (PLT) in SOFA ≥ 12 group was significantly lower than that of the SOFA < 12 group and non-sepsis group [×109/L: 28.6 (12.8, 48.9) vs. 257.3 (152.6, 339.8), 182.0 (118.0, 229.0), both P < 0.01]. There was no significant difference in prothrombin time (PT) and international normalized ratio (INR) among three groups, and it indicated that the conventional blood coagulation test might not respond quickly to the change in coagulation status of sepsis patients. As shown in the results of TEG, the values of reaction time (R value) and kinetics time (K value) in SOFA < 12 group were lower than those of the non-sepsis group [R value (minutes): 4.4 (3.6, 6.1) vs. 6.3 (6.0, 6.7), P < 0.01; K value (minutes): 1.1 (1.0, 1.5) vs. 1.5 (1.3, 1.8), P < 0.05], while they were higher in SOFA ≥ 12 group than those of the non-sepsis group [R value (minutes): 7.0 (5.7, 8.7) vs. 6.3 (6.0, 6.7), P > 0.05; K value (minutes): 4.2 (3.4, 7.1) vs. 1.5 (1.3, 1.8), P < 0.01]. The α angle, maximum amplitude (MA) and coagulation index (CI) in SOFA < 12 group were higher than those of the non-sepsis group [α angle (° ): 73.3 (68.5, 74.7) vs. 66.8 (62.2, 69.0), P < 0.01; MA (mm): 71.7 (61.9, 73.3) vs. 60.3 (58.2, 63.8), P < 0.01; CI: 3.1 (-0.1, 3.9) vs. 0.9 (-0.4, 1.3), P < 0.05], while they were lower in SOFA ≥ 12 group than those of the non-sepsis group [α angle (° ): 48.1 (36.6, 53.0) vs. 66.8 (62.2, 69.0), P < 0.01; MA (mm): 37.8 (30.0, 45.7) vs. 60.3 (58.2, 63.8), P < 0.01; CI: -5.6 (-8.4, -3.6) vs. 0.9 (-0.4, 1.3), P < 0.01]. The above results indicated that TEG could distinguish quickly the hypercoagulability and hypocoagulability status in septic patients. PCT in non-sepsis, SOFA < 12, and SOFA ≥ 12 groups were 0.27 (0.05, 1.80), 0.68 (0.10, 10.00), 41.10 (4.24, 100.00) μg/L respectively (Z = 195.475, P = 0.000), which indicate the severity of infectious disease. Correlation analysis results showed that SOFA score was negatively correlated with PLT, α angle, MA, and CI (r value was -0.853, -0.833, -0.881, and -0.859, respectively, all P = 0.000), and it was positively correlated with activated partial thromboplastin time (APTT), D-dimer, R value, K value, and PCT (r value was 0.381, 0.561, 0.587, 0.831, 0.775, respectively, P < 0.05 or P < 0.01), and non correlations was founded with PT, fibrinogen (FBG), and INR (r1 = 0.211, P1 = 0.233; r2 = -0.252, P2 = 0.142; r3 = 0.248, P3 = 0.148). Conclusions TEG can effectively monitor the change in coagulation in patients with sepsis, and distinguish the hypercoagulable and hypocoagulable state. TEG may be a valuable tool to evaluate degree and risk of sepsis objectively.
