Objective:To investigate the diagnosis and strategy of individualized functional rhinoplasty based on the overall evaluation of the nasal cavity as a integration.Methods:A prospective study was carried out in the patients who underwent endoscopic functional rhinoplasty at the Department of Otorhinolaryngology, the First Affiliated Hospital of Chongqing Medical University from February 2018 to August 2021. The overall evaluation of the internal and external structure and function of the nasal cavity was performed before surgery, and the individualized surgical strategies were developed. According to the surgical strategy, nasal septum correction, inferior turbinate ablation, inferior turbinate fracture displacement, inferior turbinate submucous resection, dorsal extended cartilage graft, crooked nose correction, prosthesis or autologous cartilage implantation, hump reduction and osteotomy were performed to adjust the nasal function and aesthetics. Internal nasal valve (INV) angle, INV collapse grade, INV cross-sectional area, and external nasal valve effectiveness (ENVE) index were used to evaluate the structure of nasal valve area. Nasal obstruction symptom assessment (NOSE) scale and nasal resistance [including total nasal resistance (RT), nasal resistance differential ratio (R 1r)] was used to evaluate nasal ventilation function. Facial clinimetric evaluation questionnaire rhinoplasty module (FACE-Q RM), rhinoplasty outcome evaluation (ROE) scale, external nasal subunit measurement was used to evaluate nasal appearance, and self-rating depression scale (SDS) and self-rating anxiety scale (SAS) was used to evaluate psychological status. Finally, the correlation between patient satisfaction and subjective and objective parameters were analyzed. The data before and after operation were compared by paired t-test. Correlation was tested by Pearson analysis. Results:A total of 50 patients were included, including 18 males and 32 females, ranging in age from 23 to 52 years, mean age 35.7 years. All patients had symptoms of nasal congestion, of which 28 cases with crooked nose deformity, 12 cases with nasal valve stenosis, 6 cases with saddle nose deformity, and 4 cases with hump nose. Compared with preoperative, postoperative INV angle was significantly increased, INV collapse grade was decreased, INV cross-sectional area was increased, ENVE index was increased ( P<0.05). After operation, the NOSE score decreased, and nasal resistance showed that RT and R 1r decreased, indicating that nasal congestion symptoms were relieved significantly ( P<0.05). The postoperative FACE-Q RM and ROE scores increased, indicating that patients’ nasal appearance satisfaction increased ( P<0.05), external nasal subunit measurement showed that the upper nasal alar width and lower nasal alar angle were reduced ( P<0.05), the measured value of residual structure has no significant change. Postoperative SDS and SAS scores were significantly lower than preoperative ones, and the difference was statistically significant ( P<0.05).Overall satisfaction was improved( P<0.05). Pearson correlation analysis showed that patient satisfaction was positively correlated with INV angle, INV cross-sectional area, ENVE index, and subjective nasal shape score (FACE-Q RM, ROE), and negatively correlated with INV collapse grade, NOSE score, and nasal resistance measurement, but had no correlation with external nasal subunit measurement. Conclusion:Combined with the overall evaluation of nasal structure, nasal ventilation function and external nasal aesthetics, it is beneficial to develop the diagnosis and treatment strategy of individualized functional rhinoplasty, so as to improve patient satisfaction.

the Piezo1-mediated Ca2+influx-induced apoptosis.

Atherosclerosis is a chronic inflammatory disease characterized by autoimmune component,ser-ving as a primary factor in cardiovascular diseases.The atherosclerotic plaques involve a variety of immune cells which mediated complex immune and inflammatory responses at each stage of the disease's progression.Notably,within atherosclerotic plaques,T-cells,as the predominant immune cells,can be differentiated into various subsets with distinct functions.These T-cell subsets modulate the progression of atherosclerosis by se-creting either pro-inflammatory or anti-inflammatory cytokines.Understanding the impact of these immune cells on the disease's development is imperative for formulating novel therapeutic strategies.This article aims to review the roles of T-cell subsets and their secreted cytokines in atherosclerosis,aiming to offer new in-sights for the scientific research and clinical management of this condition.

Objective:To investigate the diagnosis and strategy of individualized functional rhinoplasty based on the overall evaluation of the nasal cavity as a integration.Methods:A prospective study was carried out in the patients who underwent endoscopic functional rhinoplasty at the Department of Otorhinolaryngology, the First Affiliated Hospital of Chongqing Medical University from February 2018 to August 2021. The overall evaluation of the internal and external structure and function of the nasal cavity was performed before surgery, and the individualized surgical strategies were developed. According to the surgical strategy, nasal septum correction, inferior turbinate ablation, inferior turbinate fracture displacement, inferior turbinate submucous resection, dorsal extended cartilage graft, crooked nose correction, prosthesis or autologous cartilage implantation, hump reduction and osteotomy were performed to adjust the nasal function and aesthetics. Internal nasal valve (INV) angle, INV collapse grade, INV cross-sectional area, and external nasal valve effectiveness (ENVE) index were used to evaluate the structure of nasal valve area. Nasal obstruction symptom assessment (NOSE) scale and nasal resistance [including total nasal resistance (RT), nasal resistance differential ratio (R 1r)] was used to evaluate nasal ventilation function. Facial clinimetric evaluation questionnaire rhinoplasty module (FACE-Q RM), rhinoplasty outcome evaluation (ROE) scale, external nasal subunit measurement was used to evaluate nasal appearance, and self-rating depression scale (SDS) and self-rating anxiety scale (SAS) was used to evaluate psychological status. Finally, the correlation between patient satisfaction and subjective and objective parameters were analyzed. The data before and after operation were compared by paired t-test. Correlation was tested by Pearson analysis. Results:A total of 50 patients were included, including 18 males and 32 females, ranging in age from 23 to 52 years, mean age 35.7 years. All patients had symptoms of nasal congestion, of which 28 cases with crooked nose deformity, 12 cases with nasal valve stenosis, 6 cases with saddle nose deformity, and 4 cases with hump nose. Compared with preoperative, postoperative INV angle was significantly increased, INV collapse grade was decreased, INV cross-sectional area was increased, ENVE index was increased ( P<0.05). After operation, the NOSE score decreased, and nasal resistance showed that RT and R 1r decreased, indicating that nasal congestion symptoms were relieved significantly ( P<0.05). The postoperative FACE-Q RM and ROE scores increased, indicating that patients’ nasal appearance satisfaction increased ( P<0.05), external nasal subunit measurement showed that the upper nasal alar width and lower nasal alar angle were reduced ( P<0.05), the measured value of residual structure has no significant change. Postoperative SDS and SAS scores were significantly lower than preoperative ones, and the difference was statistically significant ( P<0.05).Overall satisfaction was improved( P<0.05). Pearson correlation analysis showed that patient satisfaction was positively correlated with INV angle, INV cross-sectional area, ENVE index, and subjective nasal shape score (FACE-Q RM, ROE), and negatively correlated with INV collapse grade, NOSE score, and nasal resistance measurement, but had no correlation with external nasal subunit measurement. Conclusion:Combined with the overall evaluation of nasal structure, nasal ventilation function and external nasal aesthetics, it is beneficial to develop the diagnosis and treatment strategy of individualized functional rhinoplasty, so as to improve patient satisfaction.

Objective:To investigate the prognostic factors for liver transplantation for hepatocellular carcinoma beyond UCSF criteria but without macrovascular invasion.Methods:A retrospective analysis was performed for the clinical data of the hepatocellular carcinoma patients without macrovascular invasion beyond UCSF criteria who underwent liver transplantation at our center from Jan 2018 to Jun 2023. The receiver operating characteristic curve analysis was performed to assess the predictive power of potential prognosis factors.Results:With this criteria, the 1-, 3-year overall survival rates were 94.1% and 75.0%, respectively, and the 1-, 3-year tumor free survival rates were 82.4% and 38.1%, respectively. The maximum tumor size, number of tumors, AFP, PIVKA-Ⅱ before transplantation, and whether undergo pretransplant down-stage therapy were significant prognostic factors ( P<0.05). Combining the above prognostic factors to construct the receiver operating characteristic curve yielded an area under the curve of 0.967, with a sensitivity and specificity of 0.932, 0.952, respectively. Further, the differentiation, MVI and Ki-67 were significant prognostic factors ( P<0.05). Combining pathological factors to construct the receiver operating characteristic curve yielded an area under the curve of 0.927, with a sensitivity and specificity of 0.769, 1, respectively. Conclusion:The maximum tumor diameter, number of tumors, AFP, PIVKA-Ⅱ before transplantation, and pretransplant down-stage therapy and tumor differentiation, MVI and Ki-67 are all prognostic factors of liver transplantation for hepatocellular carcinoma without macrovascular invasion beyond UCSF criteria.

Objective:To discuss the repair technique of complicated sunken upper eyelid deformation, caused by postoperative extensive adhesion within upper eyelid, by using adipose tissue transplantation or reset, and to introduce the outcomes of our clinical practice.Methods:From January 2020 to January 2022, 40 female patients (76 eyes) with complicated sunken upper eyelid deformity after double eyelid surgery were repaired in the Comprehensive Ward of Plastic Surgery, Plastic Surgery Hospital, Chinese Academy of Medical Sciences, with an average age of 34 years (19-49 years). For the sunken upper eyelid with the extensive adhesion after blepharoplasty, reasonably choosing the method of orbital septum fat redistribution, free adipose tissue clump transplantation, and dermo-fat tissue clump transplantation were of great importance. The effectiveness of surgical methods were observed.Results:The repairing surgeries, performed in 40 patients (76 eyelids), were all successful and without severe complications. 98.7% of surgeries got good outcomes appraised by other doctors, and 88.2% of patients were satisfied after follow-up for 4-28 months.Conclusions:The thorough lysis of adhesion and fat clumps distribution or transplantation could not only recover the function, but also improve the appearance of upper eyelid. The surgical method introduced in the present study is a relative ideal approach for repairing the complicated sunken upper eyelid deformation.
