Objective:To assess the effectiveness of robot-assisted mandibular angle osteotomy using the FACE-Q questionnaire.Methods:A randomized controlled clinical study was conducted in the Second Affiliated Hospital of Zhengzhou University from January 2022 to June 2023. Patients with mandibular angle hypertrophy aged 18 to 40 years old were recruited as research objects, and a randomization and supply management system (Clinflash IRT 2.0) was used to randomly assign the experimental group and control groups in a 1∶1 ratio. Before surgery, Mimics 21.0 software was used to plan the surgical approach and determine the osteotomy plane based on the head CT data of the two groups. The experimental group underwent robot-assisted mandibular angle osteotomy according to the preoperative osteotomy plan, while the control group underwent traditional manual mandibular angle osteotomy according to the preoperative design. Six months after surgery, patients filled in the FACE-Q craniofacial module scale to evaluate the surgical effect, covering 12 indicators in four aspects: appearance satisfaction (including face, jaw and smile), health-related quality of life (including appearance anxiety, psychology, social interaction and speech), postoperative function (including breathing, diet, face and pronunciation), and adverse reactions. Each indicator was scored from 0 to 100 points, with higher scores indicating better evaluation. SPSS 27.0 software was used to process the data, and the measurement data of normal distribution were expressed by Mean±SD, and t-test was used for comparison between groups. The measurement data of non-normal distribution were expressed by M ( Q1, Q3), and Mann-Whitney U test was used for the comparison between groups. P<0.05 was considered statistically significant. Results:The experimental group included 20 patients, 3 males and 17 females, with an age of (27.6±4.4) years (19 to 38 years); the control group included 20 patients, 4 males and 16 females, with an age of (27.4±3.9) years (19 to 35 years). Six months postoperatively, all patients in both groups had good wound healing, and the mandibular hypertrophy was improved to varying degrees. There were no complications such as facial paralysis, facial deviation, or pain. The FACE-Q questionnaire results showed that in terms of appearance satisfaction, the scores for the three indicators of face, mandible, and smile in the experimental group were (72.2±11.7), 86(77, 92), and (63.2±9.5) points, respectively, all higher than those in the control group, which were (49.2±9.9), 43(35.5, 50), and (48.0±7.7) points, respectively, with statistically significant differences ( P<0.01 for all); in terms of health-related quality of life, except for speech, the scores for the three indicators of appearance anxiety, psychology, and social interaction in the experimental group were higher than those in the control group [(71.0±11.5) points vs.(49.1±10.3) points, (66.7±11.7) points vs.(45.4±10.5) points, (75.0±9.7)points vs.(56.4±8.5) points], with statistically significant differences ( P<0.01 for all); in terms of postoperative function, the score for eating in the experimental group was higher than that in the control group [(83.4±10.7) points vs.(71.0±14.9) points] ( P<0.01), but there were no statistically significant differences in the other three indicators ( P>0.05 for all); in terms of adverse reaction, there was no statistically significant difference between the two groups ( P>0.05). Conclusion:The result of the FACE-Q questionnaire assessment confirmed that robot-assisted mandibular angle osteotomy can significantly improve patients’ postoperative appearance satisfaction, psychological state, social adaptability, and eating function without increasing the incidence of complications.

Objective:To investigate the value of CD64 index and C-reactive protein (CRP)/albumin (Alb) ratio (CRP/Alb) in predicting infection after modified radical mastectomy for breast cancer.Methods:The clinical data of 203 breast cancer patients who underwent modified radical mastectomy from January 2018 to August 2021 in Anhui No.2 Provincial People's Hospital were retrospectively analyzed. All cases were divided into infection group (40 cases) and non-infection group (163 cases) according to whether they were infected at the 1st month after operation. On the 1st day after operation, the serum CD64 index was measured by using flow cytometry, the serum CRP and Alb levels were measured by using immunoturbidimetry, and the CRP/Alb was calculated. The values of CD64 index and CRP/Alb in the diagnosis of infection after modified radical mastectomy for breast cancer were evaluated by using receiver operating characteristic (ROC) curve. The factors influencing infection after modified radical mastectomy for breast cancer were explored by using multivariate logistic regression.Results:The levels of CD64 index, CRP, CRP/Alb in the infection group were higher than those in the non-infection group [5.7±1.1 vs. 1.5±0.3, t = 32.05, P < 0.001; (78±13) mg/L vs. (11±3) mg/L, t = 39.26, P <0.001; 3.09±0.42 vs. 0.36±0.02, t = 57.48, P < 0.001], and the level of Alb in the infection group was lower than that in the non-infection group [(25±3) g/L vs. (32±4) g/L, t = 8.37, P < 0.001]. There were statistically significant differences in the catheterization time, CD64 index and CRP/Alb between the infection group and non-infection group (all P < 0.05); multivariate logistic regression showed that catheterization time >9 d, CD64 index >42.65 and CRP/Alb >1.25 were risk influencing factors of infection after modified radical mastectomy for breast cancer (all P < 0.001). The ROC curve results showed that the area under the curve, sensitivity, and specificity of CD64 index in the diagnosis of infection after modified radical mastectomy for breast cancer were 0.804, 89.5% and 85.4%, the CRP were 0.712, 70.6% and 76.5%, the Alb were 0.766, 72.4% and 75.4%, and the CRP/Alb ratio were 0.856, 88.0% and 90.5%. Conclusions:The CD64 index and CRP/Alb have certain values in the prediction of infection after modified radical mastectomy for breast cancer.

Objective To compare the effect of the bipolar electric coagulation and unipolar electric coagulation on cranioplasty of scalp separation. Methods The clinical data of 67 patients who underwent unilateral frontotemporal cranioplasty from 2014 to 2017 were retrospectively analyzed. According to coagulation method during operation, these patients were divided into two groups, unipolar electric coagulation group (32 cases) and bipolar electric coagulation group (35 cases). The operation time, postoperative intracranial hemorrhage, infection, epilepsy and subcutaneous effusion were compared between two groups. Results The operation time of two groups had no significant difference (P > 0.05). The incidence of intracranial hemorrhage, infection and epilepsy of two groups had no significant differences (P > 0.05). But the incidence of subcutaneous effusion in unipolar electric coagulation group was significantly higher than that in bipolar electric coagulation group: 28.1%(9/32) vs. 5.7%(2/35), P<0.05. Conclusions The use of unipolar electric coagulation during the scalp separation in cranioplasty can reduce operation time in a certain extent, but significantly increase the incidence of postoperative subcutaneous effusion.

OBJECTIVETo explore the risk factors of unplanned reoperation after radical resection for colorectal cancer.

METHODSA retrospective analysis of 60 patients (within 14 to 24 days after the initial surgery) receiving unplanned reoperation after colorectal cancer surgery in the First Affiliated Hospital of Xinjiang Medical University from January 2010 to January 2014 was carried out, comparing with 120 randomly paired patients without reoperation during the same period. Univariate and multivariate Logistic regression analysis was performed to investigate the clinicopathologic characteristics of patients in both groups.

RESULTSUnivariate logistic regression analysis showed that male, massive blood loss, diabetes, high BMI, hypertension and poorer tumor staging were selected as possible risk factors, and surgeon and laparoscopic surgery as conservative factors (all P<0.05). Multivariate logistic regression analysis revealed that massive blood loss (OR=12.935, 95% CI: 2.267 to 73.806, P=0.004), diabetes (OR=1.747, 95% CI: 1.098 to 2.777, P=0.018) and male (OR=1.805, 95% CI: 1.074 to 3.034, P=0.026) were the independent risk factors of unplanned reoperation after radical resection for colorectal cancer.

CONCLUSIONFor heavy bleeding, diabetes and male gender in patients with colorectal cancer, surgeon should pay attention to prevent the risk of postoperative unplanned reoperation.
