Objective:To investigate the differences in outcomes of surgical strategies and prognosis of patients with acute type A aortic dissection(ATAAD) during the period of COVID-19 Omicron variant epidemic compared with the non-epidemic period.Methods:Clinical data were retrospectively collected from ATAAD patients during the COVID-19 Omicron variant epidemic(December 7, 2022 to January 10, 2023) and during the non-epidemic period(December 7, 2019 to January 10, 2020) to compare the differences in surgical strategies, perioperative mortality, and perioperative complication rates in ATAAD patients during the two different periods.Results:There were 14 patients in the COVID-19 infected group and 43 patients in the control group. Patients in the infected group had a shorter mean aortic clamp time[(89.71±16.27)min vs.(110.09±28.99)min, P<0.01], a significantly higher postoperative mortality rate relative to the control group(21.43% vs. 2.33%, P=0.02), a significantly longer length of stay in the ICU(3 days vs. 2 days, P=0.04) and the duration of intubation time(34 h vs. 14 h, P<0.01), and the incidence of adverse events, mainly cerebral infarction, was higher in infected group(28.57% vs. 6.98%, P=0.03). Conclusion:During the COVID-19 Omicron variant strain epidemic, our center preferred a more conservative surgical strategy in COVID-19 infected patients. Although the COVID-19 infection increased the postoperative mortality and complication rate of ATAAD, patients still achieve a more satisfactory outcome. Therefore, surgical treatment should be timely performed for ATAAD patients.

ObjectiveTo conduct a systematic review of systematic reviews of the effect of preoperative prerehabilitation training on postoperative function of patients after total knee arthroplasty. MethodsThe systematic reviews and meta-analysis about the application of preoperative prerehabilitation training after total knee arthroplasty were retrieved from Cochrane Library, Embase, PubMed, Web of Science, Wanfang Data, CNKI and VIP database, from establishment to March 10th, 2023. The methodological quality was evaluated using AMSTAR. The meta-analysis of the reseaches without repetitive content was performed using RevMan 5.3. ResultsA total of ten systematic reviews/meta analyses were included. Compared with the routine rehabilitation, preoperative prerehabilitation training might decrease the scores of Western Ontario and McMaster Universities Osteoarthritis Index (MD = -1.34, 95%CI -1.94 to -0.74, P < 0.001), and Hospital for Special Surgery Knee Score (MD = -1.04, 95%CI -1.69 to -0.40, P = 0.001), shorten the length of hospital stay (MD = -1.01, 95%CI -1.66 to -0.36, P = 0.002), and enhance muscle strength three months after operation (SMD = 0.63, 95%CI 0.30 to 0.97, P < 0.001). ConclusionPreoperative prerehabilitation training can improve postoperative knee function, enhance muscle strength three months after operation, and shorten length of hospital stay for the patients after total knee arthroplasty.

Objective:To investigate the application of debate-based immersive experiential teaching in the nursing practice teaching of stomatology.Methods:A total of 82 nursing interns of stomatology in Beijing Tongren Hospital, Capital Medical University, were selected as research subjects and were then divided into control group and observation group using the lottery method, with 41 interns in each group. The interns in the control group received traditional teaching, while those in the observation group received debate-based immersive experiential teaching. The two groups were compared in terms of the scores of comprehensive evaluation indices, nursing thinking ability, empathy ability, and recognition of teaching. SPSS 22.0 was used to perform the chi-square test and the t-test. Results:Compared with the control group, the observation group had significant increases in the scores of theoretical examination, operation examination, nursing medical record writing, reading report writing, basic nursing, communication ability, and comprehensive performance and the total score of these dimensions ( P<0.05). Compared with the control group, the observation group also had significant increases in the scores of nursing thinking ability and empathy ability ( P<0.05). The observation group had a significantly higher degree of recognition of teaching than the control group ( P<0.05). Conclusion:In the nursing practice teaching of stomatology, debate-based immersive experiential teaching can improve the comprehensive ability, nursing thinking ability, and empathy ability of interns, with a relatively high degree of recognition of teaching.

Esophageal cancer (EC) is one of the most common aggressive malignant tumors in the digestive system with a severe epidemiological situation and poor prognosis. The early diagnostic rate of EC is low, and most EC patients are diagnosed at an advanced stage. Multiple multimodality treatments have gradually evolved into the main treatment for advanced EC, including surgery, chemotherapy, radiotherapy, targeted therapy, and immunotherapy. And the emergence of targeted therapy and immunotherapy has greatly improved the survival of EC patients. This review highlights the latest advances in targeted therapy and immunotherapy for EC, discusses the efficacy and safety of relevant drugs, summarizes related important clinical trials, and tries to provide references for therapeutic strategy of EC.

Objective:To investigate the clinical effect of combined treatment of comminuted inferior pole patellar fracture with micro-plate and tension-band wire.Methods:A retrospective cohort study was conducted in 50 patients with comminuted inferior pole patellar fracture (AO classification of type 34-A1) admitted to First Affiliated Hospital of University of Science and Technology of China from October 2018 to October 2020, including 28 males and 22 females, aged 17-77 years［(51.4±11.5)years］. A total of 23 patients were treated with micro-plate combined with tension-band wire (Group A) and 27 patients were treated with cable wire looping combined with tension-band wire (Group B). Fracture union, union time and last follow-up evaluation of knee range of motion and Bostman score were compared between the two groups. Complications (infection, internal fixation failure, internal fixation irritation, etc.) were also observed.Results:All patients were followed up for 12-18 months［(14.1±2.1) months］. All patients had bone union, with no statistical difference between Group A［(9.9±1.8)weeks］and Group B［(10.3±1.4)weeks］in union time ( P>0.05). Knee range of motion was (129.2±9.7)° in Group A at the last follow-up, better than (122.3±11.0)° in Group B ( P<0.05). Knee Bostman score was (27.6±1.8)points in Group A, showing no statistical difference from that in Group B［(26.8±1.9)points］( P>0.05). There were no postoperative complications in Group A. Two patients with tension band shedding of Kirschner wire after fracture healing were found in Group B, with no special treatment given due to no obvious discomfort. Conclusions:For comminuted inferior pole patellar fracture, micro-plate combined with tension-band wire is more effective and provides better knee mobility with no complications of implant failure as compared with cable wire looping combined with tension-band wire. Therefore, the technique deserves clinical promotion.

Objective:To investigate the association between skin advanced glycation end products (AGEs) and carotid atherosclerosis (AS) in subjects with normal glucose regulation (NGR).Methods:This was a cross-sectional study. Data from the Health Management Center of the First Affiliated Hospital of University of Science and Technology between January 2019 to June 2019 were collected. A total of 902 NGR subjects aged 40-79 were enrolled and categorized into control group (530 cases), carotid intima-media thickness (IMT) thickening group (150 cases), and carotid atherosclerosis plaque group (222 cases) based on the carotid ultrasound results. Data as follows were collected, gender, age, blood pressure, body mass index (BMI), triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), fasting blood glucose (FPG), glycosylated hemoglobin (HbA 1c) and skin AGEs. Comparison via ANOVA analysis were carried out among the 3 groups. Logistic regression analysis was used to screen the independent influencing factors of carotid atherosclerosis plaque. Spearman correlation analysis was used to evaluate the correlation between AGEs and other parameters, and receiver operating characteristic (ROC) curve was used to evaluate the efficiency of skin AGEs in predicting carotid atherosclerosis plaque in NGR subjects. Results:Among the control group, IMT thickening group and carotid atherosclerosis plaque group, gender, age, systolic blood pressure (SBP), diastolic blood pressure (DBP), TC, LDL-C, FPG, HbA 1c, AGEs were significantly different (all P<0.05). Compared with IMT thickening group, the age, SBP and AGEs of carotid atherosclerotic plaque group were higher [55 (50, 60) vs 53 (49, 56) year; 132 (122, 141) vs 126 (115, 142) mmHg(1 mmHg=0.133 kPa); 74 (67, 81) vs 72 (67, 78) AU] (all P<0.001); compared with the control group, age, LDL-C, HbA 1c and AGEs of IMT thickening group were higher [53 (49, 56) vs 48 (45, 52) year; (2.8±0.7) vs (2.7±0.7) mmol/L; 5.4% (5.2, 5.6)% vs 5.4% (5.1, 5.6)%; 72 (67, 78) vs 70 (66, 76)] (all P<0.05). Age ( OR=1.179, 95% CI: 1.107-1.255), SBP ( OR=1.045, 95% CI: 1.013-1.077), LDL-C ( OR=2.028, 95% CI: 1.036-3.969), AGEs ( OR=1.049, 95% CI: 1.000-1.100) were independent influencing factors of carotid atherosclerotic plaque in population with normal glucose regulated (all P<0.05). AGEs was positively correlated with age, HbA 1c and carotid atherosclerosis plaque ( r=0.407, 0.092, 0.172) (all P<0.01). The area under the ROC curve of skin AGEs for identifying carotid atherosclerotic plaque in NGR population was 0.650 (95% CI 0.601-0.698), the best cutoff value was 70.5, the sensitivity was 65.8%, and the specificity was 56.9%. Conclusion:Skin AGEs level is closely associated with the occurrence of carotid atherosclerosis in NGR subjects.
