Background and Objectives: The Fractional Flow Reserve and Intravascular UltrasoundGuided Intervention Strategy for Clinical Outcomes in Patients with Intermediate Stenosis (FLAVOUR) trial demonstrated non-inferiority of fractional flow reserve (FFR)-guided percutaneous coronary intervention (PCI) compared with intravascular ultrasound (IVUS)-guided PCI. We sought to investigate the cost-effectiveness of FFR-guided PCI compared to IVUS-guided PCI in Korea. Methods: A 2-part cost-effectiveness model, composed of a short-term decision tree model and a long-term Markov model, was developed for patients who underwent PCI to treat intermediate stenosis (40% to 70% stenosis by visual estimation on coronary angiography).The lifetime healthcare costs and quality-adjusted life-years (QALYs) were estimated from the healthcare system perspective. Transition probabilities were mainly referred from the FLAVOUR trial, and healthcare costs were mainly obtained through analysis of Korean National Health Insurance claims data. Health utilities were mainly obtained from the Seattle Angina Questionnaire responses of FLAVOUR trial participants mapped to EQ-5D. Results: From the Korean healthcare system perspective, the base-case analysis showed that FFR-guided PCI was 2,451 U.S. dollar lower in lifetime healthcare costs and 0.178 higher in QALYs compared to IVUS-guided PCI. FFR-guided PCI remained more likely to be cost-effective over a wide range of willingness-to-pay thresholds in the probabilistic sensitivity analysis. Conclusions Based on the results from the FLAVOUR trial, FFR-guided PCI is projected to decrease lifetime healthcare costs and increase QALYs compared with IVUS-guided PCI in intermediate coronary lesion, and it is a dominant strategy in Korea.

Objective To explore the characteristics of the inhibitory effect of Evodiamine on the proliferation of activated T cells. Methods Mononuclear cells from peripheral blood (PBMCs) were obtained from healthy donors through density gradient centrifugation, and T cells were subsequently purified by using immunomagnetic bead separation. T cell activation was induced by employing anti-human CD3 and anti-human CD28 antibodies. T cells were treated with different concentrations of EVO (0.37, 1.11, 3.33, and 10)μmol/L. Flow cytometry was applied to evaluate the proliferation index, apoptosis rate, viability, CD25 expression levels, and cell cycle distribution of T cells. The expression levels of cytokines IL-2, IL-17A, IL-4, and IL-10 were quantified by using ELISA. Results 1.11, 3.33 and 10 μmol/L EVO effectively inhibited the proliferation of activated T cells, with an IC₅₀ of (1.5±0.3)μmol/L. EVO did not induce apoptosis in activated T cells and affect the survival rate of resting T cells. EVO did not affect the expression of CD25 and the secretion of IL-2 in activated T cells. EVO arrested the T cell cycle at the G2/M phase, resulting in an increase in G2/M phase cells, and exhibited a concentration-dependent effect. EVO did not affect the secretion of IL-4, IL-10 by activated T cells, but significantly inhibited the secretion of IL-17A. Conclusion EVO did not significantly affect the activation process of T cells but inhibited T cell proliferation by arresting the cell cycle at the G2/M phase and significantly suppressed the secretion of the pro-inflammatory cytokine IL-17A, which suggests that EVO has the potential to serve as a lead compound for the development of low-toxicity and high-efficiency immunosuppressants and elucidates the mechanisms underlying the anti-inflammatory and immunomodulatory effects of the traditional Chinese medicine Evodia rutaecarpa.

Objective:To compare the efficacy of acetabular magic hook plates versus quadrilateral area combined plates in treating complicated acetabular fractures.Methods:A retrospective analysis was conducted on 44 cases of complicated acetabular fractures treated at the Department of Orthopaedics, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, from June 2017 to August 2022. Among these cases, 21 were treated with magic hook plate internal fixation (hook plate group) and 23 with quadrilateral area combined plate internal fixation (combined plate group). In the hook plate group, there were 15 males and 6 females, with an average age of 43.1±11.8 years. According to the Letournel-Judet classification, there were 13 double-column fractures, 5 anterior column with posterior semi-transverse fractures, and 3 T-type fractures. Additionally, 8 cases were classified as B2.2 type, 5 as C1 type, 4 as C2 type, and 4 as C3 type; 15 cases were APQ1 type and 6 were APQ2 type. In the combined plate group, there were 16 males and 7 females, with an average age of 41.7±12.8 years. This group included 15 double-column fractures, 6 anterior column with posterior semi-transverse fractures, and 2 T-type fractures. Additionally, there were 8 cases of B2.2 type, 6 cases of C1 type, 4 cases of C2 type, and 5 cases of C3 type; 15 cases were APQ1 type and 8 were APQ2 type. Comparative analyses included operative time, intraoperative blood loss, fracture healing time, Matta standard assessment, modified Merle d'Aubign-Postel scores, and postoperative complications.Results:All 44 patients were followed up for 10 to 24 months, with an average follow-up of 14 months. The acetabular fractures healed in all cases. The healing time was 3.6±0.9 months for the hook plate group and 3.7±0.9 months for the combined plate group, with no significant difference between the groups ( t=0.549, P=0.586). The hook plate group had an operative time of 138.3±30.7 minutes and intraoperative blood loss of 735.7±159.8 ml, compared to 163.9±48.7 minutes and 843.5±181.1 ml, respectively, in the combined plate group, both of which were statistically significant ( P<0.05). The reduction quality was excellent in 13 cases, good in 5 cases, and poor in 3 cases in the hook plate group, with an excellent and good rate of 86% (18/21). In the combined plate group, the reduction quality was excellent in 13 cases, good in 6 cases, and poor in 4 cases, with an excellent and good rate of 83% (19/23), showing no significant difference between the groups (χ 2=0.143, P=0.931). The modified Merle d'Aubign Postel scores of the hook plate group were 13.8±2.2 points, 15.3±2.5 points and 16.7±1.8 points at 3 months, 6 months and the last follow-up, respectively, and the combined plate group were 13.1±1.9 points, 14.6±2.1 points and 16.4±2.0 points, respectively ( P>0.05). However, both groups showed statistically significant improvements in hip function over time ( F=9.658, P<0.001; F=16.195, P<0.001). Wound fat liquefaction and lateral femoral cutaneous nerve injury occurred in one case each in both groups. In the combined plate group, there were 3 cases of incision fat liquefaction, 2 cases of lateral femoral cutaneous nerve injury, and 1 case of traumatic hip arthritis. No other complications such as incision infection, iliac vascular injury, or loss of internal fixation were observed in either group. Conclusion:Both magic hook plate fixation and quadrilateral area combined plate fixation are safe and effective for treating complex acetabular fractures. However, magic hook plate fixation offers advantages in reducing operative time and intraoperative blood loss, thereby simplifying and enhancing the safety of the procedure.

Objective The aim of this study was to investigate the expression of miR-320a and cephalospermoma syndrome protein(CYLD)in patients with gastric cancer and its relationship with clinicopathological characteristics and prognosis. Methods A total of 460 patients with gastric cancer underwent tumor resection in our hospital from March 2013 to November 2014 were enrolled. Tumor tissues,non-tumor gastric mucosa tissues and normal tissues were collected. The expression of miR-320a and CYLD at levels of mRNA and protein were detected by Real-Time PCR,immunohistochemistry and Western blotting. The relationship between the expression of miR-320a and CYLD,and the clinicopathological features&prognosis of gastric cancer patients was analyzed. Results The relative expression of miR-320a and CYLD at the mRNA level in tumor tissues was(0. 37 ± 0. 09),(0. 91 ± 0. 23),and the relative expression in non-tumor tissues was(0. 86 ± 0. 15),(1. 56 ± 0. 42),respectively. The relative expression of miR-320a and CYLD mRNA in tumor tissues was significantly different from non-tumor tissues(t=60. 078,29. 113,P=0. 000),the positive ex-pression rate of CYLD protein in tumor tissues was 43. 48% when compared to 73. 91% in non-tumor tissues. The difference was statistically significant(χ2=86. 624,P=0. 003). The expression level of miR-320a was significantly associated with the diameter of the tumor and lymph node metastasis(χ2=25. 859 and 13. 742,P<0. 05). The expression of CYLD was also significantly associated with the TNM stage and degree of tumor differentiation(χ2=37. 725 and 59. 323,P<0. 05). The median survival of patients with low miR-320a expression(20. 36 months,95% CI:19. 252 ~21. 462 months) and those with high miR -320a expression(28. 29 months,95% CI:27.158~29.412 months)were statistically significant(χ2=87.967,P<0.001).The median survival of patients with CYLD negative expression(17. 70 months,95% CI:16. 599~18. 796 months)and those with CYLD positive expression(26. 74 months,95% CI:25. 474~27. 997 months)were statistically significant(χ2=109. 887,P<0. 001);The median survival of patients with the co-expressed miR-320a and CYLD was(29. 01 months,95% CI:26. 831~28. 946 months)and those with the non-co-expressed miR-320a and CYLD(17. 13 months,95% CI:17. 214~19. 568 months)were statistically significant(χ2=117. 680,P<0. 001). There showed a positive correlation between the expression of miR-320a and CYLD at mRNA level(r=0. 607,P<0. 001);miR-320a at the low expression,CYLD at the negative expression,TNM staging,lymph node metastasis and degree of tumor differen-tiation were independent risk factors for the prognosis of gastric cancer(HR=1. 939,2. 180,1. 561,1. 719,1. 608,95% CI:1. 141~3.295,1.252~3.796,1.014~2.403,1.115~2.650,1.097~2.357,respectively)(P<0.05).Conclusion The expressions of miR-320a and CYLD in tumor tissues of patients with gastric cancer is significantly decreased,which is related to the occurrence and development of diseases,and poor prognosis. It is a potential target for diagnosis and treatment of gastric cancer.

Objective:To investigate and analyze the attitude and its influencing factors of traditional knowledge of Chinese medicine among students in a Traditional Chinese Medicine ( TCM) college in Shaanxi Province, and provide scientific evidence for improving the relevant institution and policies. Method:A stratified cluster sampling method was used to conduct a questionnaire survey of 1,162 students in a TCM college in Shaanxi Province. Rank sum test and multiple linear regression model were used to explore the factors affecting the attitude of students. Result:The score of attitudes towards TCM protection was(43. 09 ± 6. 50), while specialty, parental education, family members' attitudes towards TCM, evaluation of courses in TCM, had taken related courses or not, clinical practice or internship experience of TCM, and the score of correlative knowledge were the influencing factors of attitudes ( P<0 . 05 ) . Conclusion:Students of this school had a relatively positive attitude towards the protection of traditional knowledge of Chinese medicine. In order to cultivate the fresh troop for the development of TCM, it is suggested that the system of TCM courses and textbooks should be reformed so as to improve students' enthusiasm for protecting traditional knowledge of Chinese medicine and establishing a special institution.
