Objective To compare the clinical efficacy of typeⅡhybrid surgery versus Sun’s surgery in treating acute Stanford A aortic dissection. Methods A retrospective analysis was conducted on the clinical data of patients with acute Stanford A aortic dissection who were treated at the Central Hospital of Wuhan affiliated to Tongji Medical College, Huazhong University of Science and Technology from 2016 to 2022. According to the surgical method, patients were divided into a typeⅡhybrid group and a Sun’s surgery group, and the clinical efficacy of the two groups was compared. Results A total of 52 patients were included, with 22 in the typeⅡhybrid surgery group and 30 in the Sun’s surgery group. The typeⅡhybrid group consisted of 18 males and 4 females, with an average age of (58.18±6.00) years, while the Sun’s surgery group consisted of 22 males and 8 females, with an average age of (53.03±11.89) years. All surgeries were successfully completed. There were 4 (13.3%) perioperative deaths in the Sun’s surgery group, including 2 patients of multiple organ failure, 1 patient of paraplegia, and 1 patient of uncontrollable postoperative bleeding. There was 1 (4.5%) perioperative death in the typeⅡhybrid surgery group, who was suspected of acute coronary syndrome and took a loading dose of dual antiplatelet drugs preoperatively. The patient underwent secondary thoracotomy for hemostasis, was re-cannulated during the operation, and finally died of circulatory failure after implantation of intra-aortic balloon pumping. There was no statistical difference in perioperative mortality between the two groups (P=0.381). Compared with the Sun’s surgery group, the typeⅡhybrid surgery group had shorter cardiopulmonary bypass time [153.00 (135.00, 185.25) min vs. 182.50 (166.50, 196.75) min, P=0.013], aortic cross-clamping time [77.00 (70.50, 92.00) min vs. 102.50 (93.50, 109.75) min, P<0.001], postoperative ICU stay [4.00 (2.83, 6.00) days vs. 8.00 (6.38, 11.78) days, P<0.001], postoperative ventilator support time [72.00 (29.50, 93.25) h vs. 87.65 (39.13, 139.13) h, P=0.138], less intraoperative blood loss [(1586.82±209.41) mL vs. (1 806.00±292.62) mL, P=0.004], postoperative 24 h drainage volume [612.50 (507.50, 762.50) mL vs. 687.50 (518.75, 993.75) mL, P=0.409], and shorter postoperative hospital stay [18.00 (13.00, 20.25) days vs. 22.00 (17.00, 29.25) days, P=0.013]. There was no statistically significant difference in the incidence of other early postoperative complications such as secondary thoracotomy for hemostasis, tracheotomy, renal dysfunction requiring dialysis, stroke, and paraplegia between the two groups (P>0.05). Conclusion For patients with acute Stanford A aortic dissection, typeⅡhybrid surgery is safe and effective; compared with traditional Sun’s surgery, typeⅡhybrid surgery has relatively less trauma, lower incidence of complications, satisfactory short-term results, and further research is needed on long-term prognosis.

Objective:To investigate the clinical and pathological characteristics of chronic hepatitis B (CHB) with metabolic dysfunction-associated fatty liver disease (MAFLD), as well as associations with advanced fibrosis.Methods:CHB patients who underwent liver biopsy at Tianjin Second People′s Hospital from June 2016 to September 2019 were included in the study. The patients were divided into two groups based on whether they had concomitant MAFLD; a CHB group and a MAFLD-CHB group. t-tests and Chi-square tests were used to compare pathological characteristics and basic features in the two groups. Logistic regression analysis was used to analyze factors associated with advanced fibrosis. Results:The CHB group included 110 patients, and the MAFLD-CHB group included 272 patients. There were significant differences in smoking, alcohol consumption, hypertension incidence, body metabolic index, alanine aminotransferase, gamma-glutamyl transferase (GGT), high-density lipoprotein, low-density lipoprotein, fasting plasma glucose, and platelets (PLT) between the two groups (all P<0.05). The MAFLD-CHB group had a higher incidence of advanced fibrosis than the CHB group ( P<0.05). In logistic regression analysis MAFLD [odds ratio ( OR)=2.204, 95% confidence interval ( CI) 1.018-4.774, P=0.045], GGT ( OR=1.008, 95% CI 1.002-1.013, P=0.005), and PLT ( OR=0.995, 95% CI 0.991-0.999, P=0.019) were associated with advanced fibrosis (all P<0.05). In the MAFLD-CHB group type 2 diabetes ( OR=3.281, 95% CI 1.375-7.832, P=0.007), GGT ( OR=1.011, 95% CI 1.003-1.018, P=0.005), and PLT ( OR=0.993, 95% CI 0.988-0.998, P=0.004) were associated with advanced fibrosis ( P<0.05). Conclusion:Patients with MAFLD-CHB are more likely to develop advanced fibrosis than patients with CHB alone. In the MAFLD-CHB group type 2 diabetes mellitus was associated with advanced fibrosis. It is important to strictly control relevant risk factors in MAFLD-CHB patients, especially in patients with type 2 diabetes.

Objective:To identify the association between CD4 +T lymphocyte (CD4) counts and physical frailty among HIV-infected people aged 65 years and older, and evaluate whether this association will be modified by the indicators of body composition. Methods:From May to October 2022, 485 elderly HIV-infected patients receiving antiretroviral therapy (ART) were recruited from 7 antiviral treatment sites in Jiangjin District Center for Disease Control and Prevention, Chongqing. The data of basic characteristics (age and gender), living habits (smoking and drinking) and disease history (metabolic diseases, cardiovascular and cerebrovascular diseases, respiratory disease and malignant tumors) were collected through the face-to-face investigation with self-made questionnaires. Fried Frailty Scale was used to evaluate the status of physical frailty. Physical fitness (walking speed, grip strength, height, and weight) and body composition (skeletal muscle mass, body fat mass, and basal metabolic rate) were measured. The antiretroviral treatment data were obtained from the China AIDS Integrated Prevention and Treatment Data information management system. The prevalence of physical frailty was calculated among the HIV-infected patients. The potential effects of CD4 counts on physical frailty were explored by using multivariate logistic regression. Subgroup analyses were repeated in the logistic regression with muscle mass, body fat mass, and other indicators of body composition as subgroup variables to determine whether the association might be modified by body composition.Results:The age of 485 patients were (72±5) years old, of which 48.2% (234 cases) were>70 years old and 70.9% (344 cases) were male, and all of whom had initiated the ART treatment. The prevalence of physical frailty among these patients was 7.4% (36/485). Multivariate logistic regression showed that after adjusting for age, sex, smoking, drinking, body composition index, ART duration, viral load and the number of comorbidities, increased CD4 cell level was associated with decreased prevalent risk of physical frailty among elderly HIV-infected patients. For every increase of 5.0×10 7 CD4 cells/L, the prevalent risk of physical frailty decreased by 12% [ OR (95% CI): 0.88 (0.76-1.01)]. Compared with the low CD4 cell level group, the risk of physical frailty in those with normal CD4 cell level decreased by 69% [ OR (95% CI): 0.31 (0.10-0.92)]. Subgroup analysis of body composition indicators showed that the protective effect of normal CD4 cell level on physical frailty was more pronounced in the high skeletal muscle mass and high basal metabolic rate group ( Pinteraction<0.05). Conclusion:The prevalence of physical frailty among elderly HIV-infected patients is relatively lower in Chongqing, and the CD4 cell level, skeletal muscle mass and basal metabolic rate are related to physical frailty.

Objective To investigate the value of neutrophil-to-lymphocyte ratio (NLR), red blood cell distribution width-to-lymphocyte ratio (RLR), and lymphocyte-to-monocyte ratio (LMR) in predicting the prognosis of early small hepatocellular carcinoma (HCC) after radiofrequency ablation (RFA). Methods A retrospective analysis was performed for 132 patients newly diagnosed with early HCC who underwent RFA in Tianjin Second People's Hospital from September 2011 to December 2020. Preoperative data were collected and the patients were followed up to observe recurrence and overall survival (OS). The X-tile tool was used to determine the optimal cut-off values of NLR, RLR, and LMR based on 5-year survival rate and recurrence-free survival (RFS) rate, and then the patients were divided into N-R-L 0 group with 92 patients, N-R-L 1 group with 29 patients, and N-R-L 2 group with 11 patients. The chi-square test was used for comparison of categorical data between the three groups. The Kaplan-Meier method was used to plot the survival curve, and the log-rank test was used to compare RFS and OS rates between groups. The factors with statistical significance in the log-rank test were included in the multivariate Cox regression analysis to determine the risk factors for RFS and OS rates. Results There were significant differences in Child-Pugh class and albumin between the N-R-L 0, N-R-L 1, and N-R-L 2 groups ( χ 2 2=10.992 and 5.699, both P < 0.05). The 1-, 3-, and 5-year OS rates of the three groups were 100%/96.3%/90.7%, 96.6%/60.4%/41.3%, and 81.8%/46.8%/15.6%, respectively ( χ 2 =38.46, P < 0.000 1), and the 1-, 3-, and 5-year RFS rates of the three groups were 76.9%/52.5%/33.3%, 42.9%/13.1%/0, and 11.1%/0/0, respectively ( χ 2 =35.345, P < 0.000 1). The multivariate Cox regression analysis showed that tumor diameter ≥ 2 cm (hazard ratio[ HR ]=2.10, 95% confidence interval[ CI ]: 1.28-3.43, P =0.003; HR =3.67, 95% CI : 1.58-8.52, P =0.002), N-R-L score of 1 point ( HR =3.14, 95% CI : 1.81-5.46, P < 0.000 1; HR =8.27, 95% CI : 3.15-21.71, P < 0.000 1), and N-R-L score of 2 points ( HR =2.61, 95% CI : 1.06-6.42, P =0.037; HR =14.59, 95% CI : 3.96-53.78, P < 0.000 1) were independent predictive factors for RFS and OS. Conclusion N-R-L, a systemic inflammatory response marker composed of NLR, RLR, and LMR, is an independent risk factor for recurrence and survival of early small HCC after RFA, and it can be used as a useful noninvasive biomarker in combination with tumor features to predict the recurrence and survival of early HCC after RFA.

Objective To investigate the value of the hepatocellular carcinoma (HCC) risk model REAL-B score in predicting the risk of HCC in chronic hepatitis B (CHB) patients receiving antiviral therapy in comparison with mPAGE-B, aMAP and PAGE-B scores. Methods A retrospective analysis was performed for the clinical data of 1160 CHB patients who received entecavir or tenofovir treatment for more than 1 year from January 2013 to December 2015 in Tianjin Second Peolple's Hospital, and the events of HCC were recorded. The area under the ROC curve (AUC) was used to evaluate the value of REAL-B, mPAGE-B, aMAP, and PAGE-B scores in predicting HCC. The Kaplan-Meier method was used to evaluate the cumulative incidence rate of HCC at different time points, and the log-rank test was used to compare the incidence rate of HCC between the groups with different scores. The independent samples t -test was used for comparison of normally distributed continuous data between groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups; the chi-square test was used for comparison of categorical data between groups. Results Among the 1160 CHB patients, 108 (9.8%) progressed to HCC within a median follow-up time of 5.3 (5.0-6.3) years. REAL-B score had an AUC of 0.848 (95% confidence interval [ CI ]: 0.816-0.880) in predicting the onset of HCC within 5 years, followed by aMAP score (AUC=0.823, 95% CI : 0.786-0.860), mPAGE-B score (AUC=0.822, 95% CI : 0.788-0.857), and PAGE-B scores (AUC=0.780, 95% CI : 0.736-0.824). The 5-year cumulative incidence rate of HCC was 0.8% in the low-risk group (with a REAL-B score of 0-3 points), which was significantly lower than the incidence rate of 11.8% in the medium-risk group (with a REAL-B score of 4-7 points) and 35.6% with the high-risk group (with a REAL-B score of 8-13 points) ( P < 0.05). In the low-risk group, REAL-B score had a negative predictive value of 100% and 99.67%, respectively, in predicting HCC within 3 and 5 years. Conclusion REAL-B score accurately predicts the risk of HCC in CHB patients receiving antiviral therapy, with a better predictive value than the other risk models within 3 years of antiviral therapy.

Objective: To investigate the association between mental sub-health and physical fitness of Chinese adolescents, to provide a reference for promoting the physical and mental health of Chinese adolescents. Methods: A total of 16 545 adolescents (13-22 years) were selected by random cluster sampling in six major administrative regions in China. The psychological part of the Multidimensional Sub-health Questionnaire of Adolescents (MSQA) and the physical fitness index test were used to assess mental sub-health and physical fitness, respectively. The chi-square test and Logistic regression analysis were used to analyze and compare the relationships between different levels of physical fitness and mental sub-health. Results: The overall detection rate of mental sub-health status among high-grade physical fitness index adolescents was 11.9%, and the detection rate among low-grade physical fitness index youths was 26.0%, and the difference was statistically significant (χ2=970.73，P<0.05). The overall detection rate among high-grade physical fitness index boys was 11.1%, and that of low-grade physical fitness index boys was 24.4%. The difference was statistically significant (χ2=566.12，P<0.05). The overall detection rate of mental sub-health status among high-level physical fitness index girls was 12.8%, and that among low-level physical fitness index girls was 27.6%, and the difference was statistically significant (χ2=412.25，P<0.05). After adjusting for gender, age, BMI, and region in the Logistic regression model, the detection rate of mental sub-health status of adolescents with low-grade physical fitness index was 2.35 times higher than that of high-grade physical fitness index adolescents(95%CI=2.12-2.61). Conclusion Adolescents with poor physical fitness have a higher risk of mental sub-health.Attention should be paid to adolescent physical fitness development to comprehensively improve physical and mental health development.

Objective:To explore the short-term outcomes of a 3D printed trabecular block cage to assist posterior internal fixation for the treatment of patients with basilar invagination and atlantoaxial dislocation.Methods:Between June 2017 and February 2019, 12 patients with basilar invagination and atlantoaxial dislocation underwent atlantoaxial distraction and posterior internal fixation at Department of Orthopedics, The First Affiliated Hospital to Zhengzhou University. They were 5 males and 7 females, aged from 34 to 62 years (average, 45.6 years). 3D printed cages were inserted intraoperatively between the joints of the atlantoaxial lateral mass. The atlanto-dental interval interval (ADI), cervico-medullary angle (CMA) and distance from tip of the odontoid process to Chamberlain's line (DOCL) and the Japanese Orthopedic Association (JOA) scale were compared between preoperation and 12 months postoperation to observe the fusion of the joints of the atlantoaxial lateral mass.Results:Operation went on uneventfully in all the 12 patients. Operation time averaged 116.5 min (from 85 to 190 min), fluoroscopy frequency 9.4 times (from 6 to 21 times), and intraoperative bleeding 82.3 mL (from 50 to 210 mL). No such postoperative complications occurred as cerebrospinal leak, cerebral infarction, or breakage, displacement or loosening of implants. All patients were followed up for 18 to 42 months (mean, 26.3 months). Their preoperative JOA, ADI, CMA and DOCL [8.33±0.98, (8.66±1.64) mm, 119.63°±4.15° and (9.66±2.15) mm] were significantly improved to 14.17±1.03, (2.63±0.59) mm, 153.76°±7.88° and (2.07±0.69) mm ( P<0.05) at 12 months postoperation. Bony fusion was achieved in all the operative segments. Conclusion:In the treatment of patients with basilar invagination and atlantoaxial dislocation, a 3D-printed trabecular block cage can be used to assist posterior internal fixation to achieve satisfactory reduction and maintain the height of joint space, leading to satisfactory short-term outcomes.

Objective: To understand the mental sub-health status of Chinese adolescents and its correlation with muscle strength index, and to provide information for relevant research in mental health and muscle strength development of Chinese adolescents. Methods: A total of 16 545 adolescents aged 13-22 year-old in six administrative regions of China were administered with the Adolescent Sub-Health Multidimensional Assessment Questionnaire (MSQA). Muscle strength indicatros were tested and its relations with mental sub-health were analyzed. Results: The detection rates of Chinese adolescents emotional problems, character problems, social adjustment difficulties, and mental sub-health status were 25.5%, 25.0%, 16.0%, and 19.7%, respectively. The detection rates of mental sub-health status of adolescents in the group of muscle index P75 were 30.3%, 19.0%, and 10.4%, respectively, and the difference was statistically significant(χ2=522.03, P<0.01). Logistic regression analysis showed that junior high school(OR=2.55), high school(OR=2.27), male students(OR=1.15), muscle index Conclusion There is a correlation between the mental sub-health of Chinese adolescents and the muscle strength index. The higher the muscle strength index, the lower detection rate of mental sub-health.

Objective: To investigate the effect of Rosuvastatin on fasting plasma glucose after coronary stent implantation in elderly patients with non-diabetes mellitus. Methods: A total of 216 non-diabetic elderly patients undergoing coronary stent implantation in our hospital from November 2015 to April 2018 were enrolled, with a follow-up in the cardiovascular department after discharge from the Hospital.The demographic data, follow-up time, and laboratory results at hospital admission and the last outpatient visit were collected retrospectively. Results: At the end of follow-up, Fasting plasma glucose(FPG)was increased in 191 patients with normal baseline FPG level as compared with the baseline level(t=-3.783, P=0.000). The incidence of new-onset diabetes was higher in the pre-diabetes group than in the normal blood glucose group(24.0% vs.2.6%, χ²=16.72, P=0.000). Conclusions Rosuvastatin increases fasting blood glucose levels in elderly non-diabetic patients after coronary stent implantation.Pre-diabetes may increase the risk for rosuvastatin-associated new-onset diabetes.
