【Objective】 To observe and analyze the influence of the improved ultra-low temperature storage box on the quality of fresh frozen plasma (FFP). 【Methods】 A total of 80 qualified whole blood samples (400 mL, O type not included) collected from July to November in 2023 were selected, and were divided into 4 groups, with 20 samples in each group. Group A: quick-frozen in a traditional low temperature box for 1 hour and then stored in a -30℃ cold storage; Group B: quick-frozen in the flat freezer for 1 hour and then stored in a -30℃ cold storage; Group C: quick-frozen in a newly improved ultra-low temperature storage box for 1 hour and stored in a -30℃ cold storage; Group D: quick-frozen in a new improved ultra-low temperature storage box for 12 hours and stored in a -30℃ cold storage. The contents of FⅧ and fibrinogen (Fg) in four groups were detected. 【Results】 The contents of FⅧ in group B, C and D were significantly higher than those in group A, with statistical difference (P0.05), and no statistical difference in the contents of Fg was found among the four groups(P>0.05). 【Conclusion】 The improved ultra-low temperature storage box is superior to the traditional low temperature box in preparing FFP, and there is no obvious difference between the improved ultra-low temperature storage box and the flat-plate quick freezer. However, the improved ultra-low temperature storage box can make the process of preparing FFP more flexible and improve the efficiency of component preparation.

BACKGROUND:Superior lower limb mobility is regarded as one of the prerequisites for winning competitions.Wearable resistance training can effectively overcome the deficiency in the transfer efficiency of traditional strength training in enhancing lower limb mobility.Considering that the impact of wearable resistance training based on different body parts on lower limb mobility may have significant differentiated characteristics,it is particularly important to review and summarize the specific application strategies and acute and chronic intervention effects. OBJECTIVE:To comb and analyze acute and chronic intervention effects of wearable resistance training based on different body parts on lower limb mobility,in order to provide insightful and methodological references for optimizing application strategies for lower limb movement ability. METHODS:A literature search was conducted in CNKI,Wanfang,VIP,Web of Science,Medline,SPORTDiscus,and PubMed databases for publications up to October 2023.Chinese and English search terms were"arm,forearm,limb,leg,lower extremity,vest,trunk,resist,weight,load,sprint,agility,change of direction".A total of 60 articles were ultimately included for review after screening the retrieval results. RESULTS AND CONCLUSION:(1)Trunk loading of 6-20%of body mass is suitable for optimizing acceleration in sprinting,while trunk loading of≤6%body mass is suitable for optimizing high-speed running.A trunk load of 5%body mass is applicable for optimizing change-of-direction movement;forearm,calf,or thigh loading often uses 1%or 2%body mass.(2)Trunk loading optimizes the functional performance of the lower limb stretch-shortening cycle by increasing vertical load.This enhances the efficiency of ground reaction force utilization and strengthens the coordinated stability control of the whole body musculature.Forearm loading effectively enhances the driving force of the upper limb swing,improves the propulsive force of the lower limb sprint,and optimizes the efficiency of inter-limb coordination.Calf loading can impose restrictions on the function of the hip joint,thereby leading to localized load stimulation and compensatory functional enhancement in the knee or ankle joint.Thigh loading partially restricts the peak extension angle and speed of the knee joint,creates specific load stimulation at the hip joint,and significantly improves its rotational kinetic energy output.(3)During larger-angle change-of-direction movements,the impact of calf loading is more significant than thigh loading.Thigh loading stimulation helps to enhance power output,while calf loading stimulation aids in improving stability control and directional change.(4)Currently,wearable resistance training has been proven to be an effective way to improve sprint and change-of-direction performance.The methodological strategies to improve sprint performance are relatively mature,but the optimal application scheme to improve change-of-direction performance needs to be further refined and optimized.Further research is recommended to supplement this area.

It is generally believed that high-quality Bupleurum scorzonerifolium roots possess specific morphological characteristics, being red, robust, and long with strong odor. However, the scientific connotation of these characteristics has not been elucidated. According to the theory of "quality evaluation through morphological identification", we studied the correlations between appearance traits(the RGB value of root surface, root length, root diameter, dry weight, and ratio of phloem to xylem) and content of main chemical components(volatile oils, total saponins, total flavonoids, total polysaccharides, and seven saikosaponins) of B. scorzonerifolium roots. Epson Scanner and ImageJ were used to scan the root samples and measure the appearance traits. Ultraviolet spectrophotometry and HPLC were employed to determine the content of chemical components. The correlation, regression, and cluster analyses were performed to study the correlations between the appearance traits and the content of chemical components. The results showed that the content of volatile oils and saikosaponins were significantly correlated with RGB value, root length, and root diameter, indicating that within a certain range, the roots being redder, longer, and thicker had higher content of volatile oils and saikosaponins. According to the appearance traits and chemical component content, the 14 samples from different producing areas were classified into four grades, and the differences in morphological traits and chemical component content were consistent among different grades. The findings in this study demonstrate that appearance traits(RGB value, root length, and root diameter) can be used to evaluate the quality of B. scorzonerifolium roots. Meanwhile, this study lays a foundation for establishing an objective quality evaluation method for B. scorzonerifolium roots.

OBJECTIVE@#Programmed cell death 6 (PDCD6), a Ca 2+-binding protein, has been reported to be aberrantly expressed in all kinds of tumors. The aim of this study was to explore the role and mechanism of PDCD6 in hepatocellular carcinomas (HCCs).@*METHODS@#The expression levels of PDCD6 in liver cancer patients and HCC cell lines were analyzed using bioinformatics and Western blotting. Cell viability and metastasis were determined by methylthiazol tetrazolium (MTT) and transwell assays, respectively. And Western blotting was used to test related biomarkers and molecular pathway factors in HCC cell lines. LY294002, a PI3K inhibitor inhibiting AKT, was used to suppress the AKT/GSK3β/β-catenin pathway to help evaluate the role of this pathway in the HCC carcinogenesis associated with PDCD6.@*RESULTS@#The analysis of The Cancer Genome Atlas Database suggested that high PDCD6 expression levels were relevant to liver cancer progression. This was consistent with our finding of higher levels of PDCD6 expression in HCC cell lines than in normal hepatocyte cell lines. The results of MTT, transwell migration, and Western blotting assays revealed that overexpression of PDCD6 positively regulated HCC cell proliferation, migration, and invasion. Conversely, the upregulation of PDCD6 expression in the presence of an AKT inhibitor inhibited HCC cell proliferation, migration, and invasion. In addition, PDCD6 promoted HCC cell migration and invasion by epithelial-mesenchymal transition. The mechanistic investigation proved that PDCD6 acted as a tumor promoter in HCC through the AKT/GSK3β/β-catenin pathway, increasing the expression of transcription factors and cellular proliferation and metastasis.@*CONCLUSION@#PDCD6 has a tumor stimulative role in HCC mediated by AKT/GSK3β/β-catenin signaling and might be a potential target for HCC progression.

The fenrou zhijian is defined as potential gap between different layers in the three-dimensional network structure formed by the twelve meridian tendons. Various pathological changes of the meridian tendons lead to the adhesion and closure of fenrou zhijian, causing abnormal mechanical conduction of the meridian tendon system, which in turn leads to painful bi syndrome of meridian tendons. As such, restarting the fenrou zhijian is the key to acupuncture treatment for painful bi syndrome of meridian tendons. Under the guidance of musculoskeletal ultrasound, the level and the angle of needle insertion of acupuncture at fenrou zhijian could be accurately controlled, the efficacy of acupuncture is improved.

Objective:To compare the abilities of different neural networks to generate pseudo-computed tomography (CT) images from magnetic resonance imaging (MRI) images and to explore the feasibility of pseudo-CT for clinical radiotherapy planning.Methods:A total of 29 brain cancer patients with planning CT and diagnostic MRI were selected. 23 of these patients were used for training neural networks and 6 for testing pseudo-CT images. Cycle-consistent generative adversarial network (cycleGAN), contrastive learning for unpaired image-to-image translation (CUT), and improved network denseCUT proposed in this study were applied to generate pseudo-CT images from MRI images. The pseudo-CT images were imported into a clinical treatment planning system to verify the feasibility of applying this method to radiotherapy planning.Results:The comparison between the generated pseudo-CT images and real CT images showed that the mean absolute errors were (72.0±6.9), (72.5±8.0), and (64.6±7.3) HU for the cycleGAN, CUT, and denseCUT, respectively. Meanwhile, the structure similarity indices were 0.91±0.01, 0.91±0.01, and 0.93±0.01, respectively. The peak signal-to-noise ratios were (28.5±0.7), (28.5±0.7), and (29.5±0.7) dB, respectively. The 2%/2 mm γ passing rates were 98.05%, 97.92%, and 98.31% for the cycleGAN, CUT, and denseCUT, respectively.Conclusions:DenseCUT can generate more accurate pseudo-CT images and the pseudo-CT can meet the demand for the dose calculation of IMRT plan.

OBJECTIVES@#To investigate the clinical treatment outcomes and the changes of the outcomes over time in extremely preterm twins in Guangdong Province, China.@*METHODS@#A retrospective analysis was performed for 269 pairs of extremely preterm twins with a gestational age of <28 weeks who were admitted to the department of neonatology in 26 grade A tertiary hospitals in Guangdong Province from January 2008 to December 2017. According to the admission time, they were divided into two groups: 2008-2012 and 2013-2017. Besides, each pair of twins was divided into the heavier infant and the lighter infant subgroups according to birth weight. The perinatal data of mothers and hospitalization data of neonates were collected. The survival rate of twins and the incidence rate of complications were compared between the 2008-2012 and 2013-2017 groups.@*RESULTS@#Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of severe asphyxia and smaller head circumference at birth (P<0.05). The mortality rates of both of the twins, the heavier infant of the twins, and the lighter infant of the twins were lower in the 2013-2017 group compared with the 2008-2012 group (P<0.05). Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of pulmonary hemorrhage, patent ductus arteriosus (PDA), periventricular-intraventricular hemorrhage (P-IVH), and neonatal respiratory distress syndrome (NRDS) and a higher incidence rate of bronchopulmonary dysplasia (P<0.05).@*CONCLUSIONS@#There is a significant increase in the survival rate over time in extremely preterm twins with a gestational age of <28 weeks in the 26 grade A tertiary hospitals in Guangdong Province. The incidences of severe asphyxia, pulmonary hemorrhage, PDA, P-IVH, and NRDS decrease in both the heavier and lighter infants of the twins, but the incidence of bronchopulmonary dysplasia increases. With the improvement of diagnosis and treatment, the multidisciplinary collaboration between different fields of fetal medicine including prenatal diagnosis, obstetrics, and neonatology is needed in the future to jointly develop management strategies for twin pregnancy.

Objective: To evaluate the 4-year clinical outcomes of patients following Firesorb bioresorbable scaffold (BRS) implantation. Methods: The study reported the 4-year follow-up results of the FUTURE I study. FUTURE I was a prospective, single-center, open-label, first-in-man study which evaluated the feasibility, preliminary safety, and efficacy of Firesorb stent in the treatment of coronary artery stenosis. A total of 45 patients with single de novo lesions in native coronary arteries ,who hospitalized in Fuwai Hospital from January to March 2016 were enrolled. After successfully stent implantation these patients were randomized in a 2∶1 ratio into cohort 1 (n=30) or cohort 2 (n=15). The patients in cohort 1 underwent angiographic, IVUS or OCT examination at 6 months and 2 years; and cohort 2 underwent angiographic, IVUS or OCT at 1 and 3 years. All patients underwent clinical follow-up at 1, 6 months and 1 year and annually thereafter up to 5 years. The primary endpoint was target lesion failure (TLF, including cardiac death, target vessel myocardial infarction, and ischemia-driven target lesion revascularization). Secondary endpoints included patient-oriented composite endpoint (PoCE, defined as composite of all death, all miocardial infarction, or any revascularization). Results: A total of 45 patients were enrolled and implanted with Firesorb BRS, including 35 males (77.8%), and the age was (54.4±9.3) years. At 4 years, 10 patients in cohort 1 were reexamined by coronary angiography and OCT examination. Among them, 2 patients' stents were completely degraded and absorbed. Compared with the OCT images of the other 8 patients in cohort 2 at 3 years, the degree of stent degradation was increased, and no stent adherence was found. The 4-year clinical follow-up rate was 100%. In 4-year clinical following up, 2 patients suffered PoCE (4.4%): 1 patient underwent non-target vessel revascularization the day after index procedure and target vessel revascularization (Non-target lesion revascularization) at 2-year imaging follow-up; the other patient underwent target lesion revascularization during imaging follow-up at 4 years but not due to ischemic driven. There was no scaffold thrombosis or TLF events through 4 years. Conclusions: Four years after the implantation, complete degradation and absorption of the Firsorb stent are evidenced in some patients. Firesorb stent is feasible and effective in the treatment of patients with non-complex coronary lesions.

Objectives: To compare the impact of ticagrelor or clopidogrel on serum uric acid levels among patients with ST-segment elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention (PCI) and further evaluate the effects of variation of serum uric acid levels on platelet reactivity. Methods: STEMI patients who admitted to Fuwai Hospital from April 2017 to January 2020, and underwent primary PCI and discharged alive with aspirin and ticagrelor or clopidogrel were included in this study. Patients were divided into ticagrelor group and clopidogrel group. The baseline clinical data were collected. Serum uric acid and creatinine levels at baseline and 30 days post-PCI were measured. Light transmittance aggregometry was used to assess maximum aggregation rate induced by adenosine diphosphate and arachidonic acid. The changes of serum uric acid and creatinine were compared between the two groups. Multivariate logistic regression was performed to evaluate independent related factors for rise in the uric acid levels, and the effect of variation of serum uric acid level on platelet reactivity was analyzed. Results: A total of 967 patients were included, the age was (59.4±12.1) years, and 163 case were female. There were 550 cases in ticagrelor group (56.9%) and 417 cases in clopidogrel group (43.1%). Baseline serum uric acid and creatinine levels were similar between the 2 groups. At 30 days, the serum uric acid level [(347.2±96.5) mmol/L vs. (341.2±105.3) mmol/L, P=0.009] and absolute [46.4 (-2.4, 88.1) mmol/L vs. 25.0 (-21.9, 73.0) mmol/L, P=0.001] and percentage [13.2 (-0.01, 29.0) % vs. 7.9 (-5.7, 25.0) %, P=0.007] increase in the serum uric acid levels were significantly higher in ticagrelor group than in clopidogrel group. The level of serum creatinine at 30 days was significantly lower in ticagrelor group than in clopidogrel group [(89.7±21.3) μmol/L vs. (94.4±43.9) μmol/L, P<0.05], whereas there were no differences in absolute [8.0 (-1.4, 16.6) μmol/L vs. 7.8 (-2.0, 16.6) μmol/L] and percentage [10.5 (-1.7%, 22.6%) vs. 9.8 (-2.4%, 22.1%)] change in the serum creatinine between the 2 groups (all P>0.05). Logistic regression analysis showed that, after adjusting for confounding factors, ticagrelor therapy was an independent related factor of serum uric acid elevation (OR=1.582, 95% CI:1.023-2.447, P=0.039). The variation of the serum uric acid levels did not affect platelet aggregation and the percentage of high platelet reactivity in both groups. Conclusions: Ticagrelor use is related to a significant increase in the serum uric acid levels at 30 days post-PCI in this patient cohort. The variations in the uric acid levels do not increase the percentage of high platelet reactivity in STEMI patients treated with ticagrelor or clopidogrel.

Objective: To investigate the short-term efficacy of anti-IgE monoclonal antibody (Omalizumab) in the treatment of recurrent chronic rhinosinusitis with nasal polyps (CRSwNP) complicated with asthma. Methods: Patients with recurrent CRSwNP and comorbid asthma in Beijing TongRen Hospital from May to December of 2020 were continuously recruited and received a 4-month therapy of stable background treatment plus Omalizumab. Results of visual analog scales (VAS) of nasal symptoms, sino-nasal outcome test-22 (SNOT 22) and nasal polyp scores were collected at baseline and post-treatment (1, 2, 3 and 4 months after treatment). Blood routine tests, total nasal resistances (TNR), minimum cross-sectional areas (MCA), total nasal cavity volumes (NCV), forced expiratory volumes in one second (FEV1)/forced vital capacity (FVC) and adverse events were collected at baseline and 4 months after treatment. All results were evaluated for short-term efficacy of Omalizumab. GraphPad Prism 8.2.1 was used for statistic analysis. Results: Ten patients were collected, including 3 males and 7 females, aged (41.13±12.64) years old (x¯±s). Compared to results at baseline, the VAS scores of nasal obstruction, rhinorrhea, hyposmia and headache after 4 months treatment were significantly decreased (1.80±1.48 vs 6.70±2.83, 2.40±1.27 vs 6.40±3.44, 2.70±2.91 vs 8.20±2.25, 0.60±1.08 vs 3.60±2.72, t value was 5.045, 4.243, 5.312, 3.402, respectively, all P<0.01). The scores of SNOT-22 (25.6±20 vs 61.3±33.32, t=4.127, P=0.002 6), nasal polyp scores (2.20±0.92 vs 4.60±0.84, t=9.000, P<0.01) and the count and percentage of eosinophils in peripheral blood were significantly decreased ((94.10±97.78)×109/L vs (360.00±210.80)×109/L, (32.90±27.06)% vs (64.40±20.73)%, t value was 3.678, 2.957, respectively, all P<0.05). NCV (0-5 cm and 0-7 cm) of patients were improved from baseline ((12.62±2.84) cm3 vs (10.40±2.09) cm3, (27.50±14.15) cm3 vs (16.81±6.40) cm3, t value was 2.371, 2.445, respectively, all P<0.05). Conclusions: The 4-month treatment of Omalizumab can significantly improve the nasal symptoms and quality of life of patients with recurrent CRSwNP complicated with asthma, shrink nasal polyps size and reduce the number of peripheral blood eosinophils. Omalizumab can be used as an alternative therapy for refractory CRSwNP patients in the future.

Objective:To explore the value of pre- and postoperative red cell distribution width-to-lymphocyte count ratio (RLR) in predicting the disease-free survival (DFS) for non-metastatic colorectal cancer patients.Methods:The data of 108 patients pathologically diagnosed with non-metastatic colorectal adenocarcinoma after surgery from December 2012 to January 2020 in Hainan Hospital of PLA General Hospital were retrospectively analyzed. RLR was calculated and its differences in patients with varied clinicopathological characteristics were analyzed. The receiver operating characteristics (ROC) curve was applied to analyze the value of pre- and postoperative RLR in predicting DFS of patients, and the cut-off value was determined by Youden index. DFS of patients with different stratification stratified by a cut-off value of RLR was analyzed by using Kaplan-Meier method followed by log-rank test. Cox proportional hazards model was used to make univariate and multivariate analysis.Results:Youden index of pre- and postoperative RLR in predicting DFS was 8.86%, 9.15%; based on the above index, the patients were divided into the preoperative RLR<8.86% group (73 cases) and preoperative RLR≥8.86% group (35 cases), postoperative RLR<9.15% group (48 cases) and postoperative RLR≥9.15% group (60 cases). According to ROC curve, the area under the curve (AUC) of preoperative RLR in predicating DFS was 0.66 (95% CI 0.55-0.77, P = 0.01), and AUC of postoperative RLR in predicating DFS was 0.62 (95% CI 0.51-0.74, P = 0.04). Pre- and postoperative RLR cut-off values were used to predict 3-year DFS rate of patients with the sensitivity of 51.60% and 71.00%, respectively, and the specificity of 76.60% and 50.60%, respectively. Kaplan-Meier analysis showed that patients in preoperative RLR<8.86% group had a better DFS compared with those in preoperative RLR≥8.86% group ( χ2 = 7.35, P < 0.01); there was no statistical difference in DFS between postoperative RLR<9.15% group and postoperative RLR≥9.15% group ( χ2 = 3.69, P = 0.06). Preoperative RLR was an independent affecting factor for DFS of patients ( HR = 1.13, 95% CI 1.04-1.22, P <0.01). Conclusions:Pre- and postoperative RLR could be useful in predicating 3-year DFS for patients with non-metastatic colorectal cancer. Preoperative RLR is an independent affecting factor for DFS, and the patients with low RLR have a better prognosis.

BACKGROUND@#The Chinese appropriate use criteria (AUC) for coronary revascularization was released in 2016 to improve the use of coronary revascularization. This study aimed to evaluate the association between the appropriateness of coronary revascularization based on the Chinese AUC and 1-year outcomes in stable coronary artery disease (CAD) patients.@*METHODS@#We conducted a prospective, multi-center cohort study of stable CAD patients with coronary lesion stenosis ≥50%. After the classification of appropriateness based on Chinese AUC, patients were categorized into the coronary revascularization group or the medical therapy group based on treatment received. The primary outcome was a composite of death, myocardial infarction, stroke, repeated revascularization, and ischemic symptoms with hospital admission.@*RESULTS@#From August 2016 to August 2017, 6085 patients were consecutively enrolled. Coronary revascularization was associated with a lower adjusted hazard of 1-year major adverse cardiovascular and cerebrovascular events (MACCEs; hazard ratio [HR]: 0.62; 95% confidence interval [CI]: 0.45-0.86; P = 0.004) than medical therapy in patients with appropriate indications (n = 1617). No significant benefit in 1-year MACCEs was found after revascularization compared to after medical therapy in patients with uncertain indications (n = 2658, HR: 0.81; 95% CI: 0.52-1.25; P = 0.338) and inappropriate indications (n = 1810, HR: 0.80; 95% CI: 0.51-1.23; P = 0.308).@*CONCLUSIONS@#In patients with appropriate indications according to Chinese AUC, coronary revascularization was associated with significantly lower risk of MACCEs at 1 year. No benefit was found in coronary revascularization in patients with inappropriate indications. Our findings provide evidence for using Chinese AUC to guide clinical decision-making.@*CLINICAL TRIAL REGISTRATION@#NCT02880605. https://www.clinicaltrials.gov.
Résumé
BACKGROUND@#Imprecise interpretation of coronary angiograms was reported and resulted in inappropriate revascularization. Synergy Between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) score is a comprehensive system to evaluate the complexity of the overall lesions. We hypothesized that a real-time SYNTAX score feedback from image analysts may rectify the mis-estimation and improve revascularization appropriateness in patients with stable coronary artery disease (CAD).@*METHODS@#In this single-center, historical control study, patients with stable CAD with coronary lesion stenosis ≥50% were consecutively recruited. During the control period, SYNTAX scores were calculated by treating cardiologists. During the intervention period, SYNTAX scores were calculated by image analysts immediately after coronary angiography and were provided to cardiologists in real-time to aid decision-making. The primary outcome was revascularization deemed inappropriate by Chinese appropriate use criteria for coronary revascularization.@*RESULTS@#A total of 3245 patients were enrolled and assigned to the control group (08/2016-03/2017, n = 1525) or the intervention group (03/2017-09/2017, n = 1720). For SYNTAX score tertiles, 17.9% patients were overestimated and 4.3% were underestimated by cardiologists in the control group. After adjustment, inappropriate revascularization significantly decreased in the intervention group compared with the control group (adjusted odds ratio [OR]: 0.83; 95% confidence interval [CI]: 0.73-0.95; P = 0.007). Both inappropriate percutaneous coronary intervention (adjusted OR: 0.82; 95% CI: 0.74-0.92; P < 0.001) and percutaneous coronary intervention utilization (adjusted OR: 0.88; 95% CI: 0.79-0.98; P = 0.016) decreased significantly in the intervention group. There was no significant difference in 1-year adverse cardiac events between the control group and the intervention group.@*CONCLUSIONS@#Real-time SYNTAX score feedback significantly reduced inappropriate coronary revascularization in stable patients with CAD.@*CLINICAL TRIAL REGISTRATION@#Nos.

Résumé
Objective:To explore the value of tumor diameter to preoperative carcinoembryonic antigen (CEA) ratio (TCR) in predicting prognosis of patients with non-metastatic colorectal cancer.Methods:The clinical data of 144 patients with colorectal cancer in Hainan Hospital of PLA General Hospital between July 2012 and December 2017 were retrospectively analyzed. Patients were divided into the low TCR group and the high TCR group according to the optimal value of TCR in predicting the disease-free survival (DFS) determined by the receiver operating characteristic curve (ROC). The clinicopathological features of both groups were analyzed, and the influencing factors of DFS were also analyzed by using Cox proportional hazard model.Results:ROC analysis showed that TCR had a certain value in predicting DFS, and area under the curve (AUC) was 0.614 (95% CI 0.507-0.722); when the value of TCR was set at 0.690, the sensitivity and specificity of predicting the 3-year DFS rate was 46.3% and 70.9%, respectively. According to 0.690 of TCR, there were 50 cases in the low TCR (< 0.690) group and 94 cases in the high TCR (≥0.690) group. There were no statistically significant differences in the high and low TCR between the two groups for patients stratified by gender, age, tumor location, differentiation degree, invasive depth, lymph node metastasis, TNM stage (all P > 0.05). Univariate analysis showed that TCR, preoperative CEA level and TNM stage played a role in predicting DFS of patients (all P < 0.05), while Cox multivariate analysis indicated that TCR < 0.690 ( HR = 2.369, 95% CI 1.279-4.388, P = 0.006) and Ⅲ stage in TNM stage ( HR = 2.214, 95% CI 1.346-3.640, P = 0.002) were the independent risk factors of influencing DFS (all P < 0.01). The 3-year DFS rate of patients in the low TCR group was lower than that of those in the high TCR group (62.0% vs. 83.0%, P = 0.007). Conclusion:TCR could have a certain value in judging the prognosis of non-metastatic colorectal cancer patients, and low TCR patients have a poorer prognosis.
