METHODS Serum TFF3 and carcino-embryonic antigen(CEA) were detected in 527 individuals, including 115 healthy control(HC), 198 colorectal adenoma(CA), and 214 CC individuals in the training group. RESULTS Serum TFF3 showed no significant correlation with age, gender, or tumor location but showed significant correlation with the tumor stage. Serum TFF3 in the CC group was significantly higher than in the HC or CA group. The AUC values of TFF3 for discriminating between HC and CC and between CA and CC were 0.930(0.903, 0.958) and 0.834(0.796, 0.873). A multivariate model combining TFF3 and CEA was built. Compared to TFF3 or CEA alone, the multivariate model showed significant improvement(P < 0.001). For discriminating between HC and CC, HC and early stage CC, HC and advanced stage CC, CA and CC, CA and early stage CC, and CA and advanced stage CC in the training group, the sensitivities were 92.99%, 91.46%, 93.18%, 73.83%, 76.83%, and 81.82%, and the specificities were 91.30%, 91.30%, 93.91%, 88.38%, 77.27%, and 88.38%, respectively. After validation, the sensitivities were 89.39%, 85.71%, 90.79%, 72.73%, 71.43%, and 78.95%, and the specificities were 87.85%, 87.85%, 2.52%, 87.85%, 80.77%, and 87.50%, respectively. CONCLUSION The multivariate diagnostic model that included TFF3 and CEA showed significant improvement over the conventional biomarker CEA and might provide a potential method for the early detection of CC.展开更多

Both groups used color Doppler ultrasound to detect the blood flow of lower extremity vessels. The incidence of blood flow, vascular diameter and stenosis, occlusion and arteriosclerosis of the lower extremity were observed. <strong>Results:</strong> The blood flow and vascular di-ameter of the lower extremity in the observation group were significantly lower than those in the control group (p < 0.05). The incidence of vascular stenosis, vascular occlusion, thrombus, intimal thickening and plaque in the observation group was 85.42%, 22.92%, 10.42% and 93.75% respectively, which was significantly higher than that in the control group was 10.42%, 0.00%, 0.00% and 14.58% (p < 0.05). The incidence of lower extremity vascular lesions in the observation group was significantly higher than that in the control group (p < 0.05). <strong>Conclusion:</strong> Color Doppler ultrasound is of high diagnostic value in the diagnosis of diabetic lower extremity vascular diseases, and can be used to determine the blood flow of the lower extremity and the inner diameter of popliteal artery, thigh artery, dorsalis pedis artery and so on. At the same time, it can also clearly show the specific situation of vascular occlusion, arteriosclerosis and thrombosis, which is of great signif-icance for the prevention and diagnosis of lower extremity vascular lesions, and can provide the basis for the treatment of lower extremity vascular lesions. </div>展开更多

文摘AIM The purpose of this study was to evaluate the diagnostic value of trefoil factor family 3(TFF3) for the early detection of colorectal cancer(CC). METHODS Serum TFF3 and carcino-embryonic antigen(CEA) were detected in 527 individuals, including 115 healthy control(HC), 198 colorectal adenoma(CA), and 214 CC individuals in the training group. RESULTS Serum TFF3 showed no significant correlation with age, gender, or tumor location but showed significant correlation with the tumor stage. Serum TFF3 in the CC group was significantly higher than in the HC or CA group. The AUC values of TFF3 for discriminating between HC and CC and between CA and CC were 0.930(0.903, 0.958) and 0.834(0.796, 0.873). A multivariate model combining TFF3 and CEA was built. Compared to TFF3 or CEA alone, the multivariate model showed significant improvement(P < 0.001). For discriminating between HC and CC, HC and early stage CC, HC and advanced stage CC, CA and CC, CA and early stage CC, and CA and advanced stage CC in the training group, the sensitivities were 92.99%, 91.46%, 93.18%, 73.83%, 76.83%, and 81.82%, and the specificities were 91.30%, 91.30%, 93.91%, 88.38%, 77.27%, and 88.38%, respectively. After validation, the sensitivities were 89.39%, 85.71%, 90.79%, 72.73%, 71.43%, and 78.95%, and the specificities were 87.85%, 87.85%, 2.52%, 87.85%, 80.77%, and 87.50%, respectively. CONCLUSION The multivariate diagnostic model that included TFF3 and CEA showed significant improvement over the conventional biomarker CEA and might provide a potential method for the early detection of CC.

文摘BACKGROUND Patients with thalamic infarction experience abnormal blockages of multinuc-leated vessels,affecting the body and thereby the thalamus.Most patients with thalamic infarction have an adverse prognosis,which seriously affects their safety.Therefore,it is essential to analyze the independent risk factors that influence the prognosis of patients with thalamic infarction and develop corresponding preventive measures.AIM To explore the effect of non-high-density lipoprotein cholesterol(non-HDL-C)and Homocysteine(Hcy)levels in cognitive impairment in thalamic infarction.METHODS From March 2019 to March 2022,80 patients with thalamic infarction were divided into a group with cognitive impairment[Montreal Cognitive Assessment(MoCA)score<26;35 patients]and a group with normal cognitive function(MoCA score of 26-30;45 patients)according to the MoCA score.In addition,50 healthy people in the same period were selected as the control group.A correlation between the non-HDL-C and Hcy levels and the MoCA score and receiver operating characteristic curve was observed,and the serum non-HDL-C and Hcy levels were analyzed for the diagnosis of cognitive impairment in patients with thalamic infarction.According to the Modified Rankin Scale(MRS)score,80 patients with thalamic infarction were divided into a good prognosis group(MRS score≤2)and a poor prognosis group(MRS score>2).RESULTS The non-HDL-C and Hcy levels were significantly higher in the group with cognitive impairment than in the group with normal cognitive function(P<0.05).There was no significant difference in the non-HDL-C level between the control group and the group with normal cognitive function(P>0.05).The MoCA scores of the group with cognitive impairment were significantly lower than those of the group with normal cognitive function and the control group(P<0.05).There was a significant difference between the control group and the group with normal cognitive function(P<0.05).The non-HDL-C and Hcy levels were correlated with the MoCA score(P<0.05),cognitive impairment[areas under the curve(AUC)=0.709,95%confidence interval(95%CI):0.599-0.816],the non-HDL-C level,and could predict cognitive impairment in patients with thalamic infarction(AUC=0.738,95%CI:0.618-0.859).Hcy combined with non-HDL-C levels can predict cognitive impairment in patients with thalamic infarction(AUC=0.769,95%CI:0.721-0.895).RESULTS There were 50 patients in the good prognosis group and 30 patients in the poor prognosis group.Compared with the good prognosis group,in the poor prognosis group,the National Institutes of Health Stroke Scale(NIHSS)score,non-HDL-C level,Hcy level,large-area cerebral infarction,atrial fibrillation,and activated partial prothrombin time were statistically significant(P<0.05).The non-HDL-C level,the Hcy level,the NIHSS score,extensive cerebral serum,and atrial fibrillation may all be independent risk factors for poor prognosis in patients with thalamic infarction(P<0.05).CONCLUSION Non-HDL-C and Hcy levels are positively correlated with cognitive impairment in patients with thalamic infarction.Non-HDL-C and Hcy levels can be used in the diagnosis of cognitive impairment in patients with thalamic infarction,and the combined detection effect is better.The main factors affecting the prognosis of patients with thalamic infarction are the non-HDL-C level,the Hcy level,the NIHSS score,large-area cerebral infarction,and atrial fibrillation.Clinically,corresponding preventive measures can be formulated based on the above factors to prevent poor prognosis and reduce mortality.

Both groups used color Doppler ultrasound to detect the blood flow of lower extremity vessels. The incidence of blood flow, vascular diameter and stenosis, occlusion and arteriosclerosis of the lower extremity were observed. <strong>Results:</strong> The blood flow and vascular di-ameter of the lower extremity in the observation group were significantly lower than those in the control group (p < 0.05). The incidence of vascular stenosis, vascular occlusion, thrombus, intimal thickening and plaque in the observation group was 85.42%, 22.92%, 10.42% and 93.75% respectively, which was significantly higher than that in the control group was 10.42%, 0.00%, 0.00% and 14.58% (p < 0.05). The incidence of lower extremity vascular lesions in the observation group was significantly higher than that in the control group (p < 0.05). <strong>Conclusion:</strong> Color Doppler ultrasound is of high diagnostic value in the diagnosis of diabetic lower extremity vascular diseases, and can be used to determine the blood flow of the lower extremity and the inner diameter of popliteal artery, thigh artery, dorsalis pedis artery and so on. At the same time, it can also clearly show the specific situation of vascular occlusion, arteriosclerosis and thrombosis, which is of great signif-icance for the prevention and diagnosis of lower extremity vascular lesions, and can provide the basis for the treatment of lower extremity vascular lesions. </div>
文摘Objective: A comparison of the difference between the two types of field MR scan in diagnosis of shoulder joint injury. Method: Randomly selected 153 patients with arthroscopic or open arthroplasty who had shoulder pain or dysfunction treated in our hospital from 2014 to 2017 were divided into 1.5 T group and 3.0 according to the field strength of MRI examination. Postoperative pathology was a gold standard. The sensitivity, specificity, consistency, and predictive value of two field-strength MRI examinations in the diagnosis of rotator cuff tears were calculated and compared. Results: The sensitivity, specificity, crude consistency, positive predictive value, and negative predictive value of the 1.5 T group were 68.75%, 82.35%, 73.47%, 88.00%, and 58.33%, respectively. The 3.0 T group was 72.22%, 89.47%, 78.18%, 92.86% and 62.96%, the differences between the above indicators were not statistically significant (P > 0.05). Conclusion: There was no difference in the authenticity and benefit index of rotator cuff injury diagnosed by 1.5 T and 3.0 T MRI.

文摘Objective To study the value of the subjective visual vertical(SVV)in the diagnosis of vestibular migraine(VM).Methods This study recruited 128 VM patients and 64 age-matched normal subjects.We detected the SVV during the interval between attacks in both groups,in sitting upright,and the head tilted at 45°to the left or right.We then examined the correlation between the SVV results with the vestibular evoked myogenic potential(VEMP)and canal paresis(CP).Results It was found there was a significant difference in SVV at the upright position between VM patients and normal controls(P=0.006)and no significant difference was found at the tilts of 45°to the left or right between the two groups.The SVV results at the upright position were significantly correlated with cervical VEMP(P=0.042)whereas not significantly correlated with CP and VEMP.There existed no significant difference in the conformity to the Müller effect(M effect)between the two groups.ROC analysis exhibited that the sensitivity,specificity of SVVs at the upright were 67.200%and 62.500%respectively.The diagnostic value of SVV at the upright position was significantly higher than that at tilts of 45°to the left and right(P=0.006).Nonetheless the diagnostic accuracy was relatively low.Conclusion Abnormality in SVV possibly stems from the lasting functional disorder of cerebellar or high-level cortical centers in VM patients or is linked to the vestibular compensation.The SVV is of low diagnostic value for VM and the value of SVV in VM warrants further study.
