To identify the associations of clinical and magnetic resonance (MR) features with overall survival (OS) in patients with unresectable hepatocellular carcinoma (HCC) achieving complete response (CR) after conventional transcatheter arterial chemoembolization (TACE) and to further develop an individual nomograph to estimate the survival probability. A total of 112 patients with unresectable HCC treated with TACE as first-line treatment were retrospectively evaluated. Potential risk factors associated with OS were identified by univariate and multivariate Cox analyses. The survival model was developed by multivariate Cox proportional hazard model. The area under the receiver operating characteristic curve was calculated to assess the performance of each marker and of the whole model. Discrimination was performed using Kaplan–Meier curves, and the survival curves were compared by the log-rank test. A nomogram derived from the survival model was established. Multivariate Cox analyses indicated that nonsmooth tumor margin, peritumoral enhancement, fat sparing in solid mass, and Barcelona clinic liver cancer (BCLC) stage were independent risk indicators associated with OS. The survival model showed acceptable diagnostic power, with an area under the curve (AUC) of 0.687. Kaplan–Meier curves demonstrated that the model discriminated well, as the high-risk and low-risk groups had median survival times of 21.6 months and 34.8 months, respectively (log-rank test, P = 0.01). Nonsmooth tumor margin, peritumoral enhancement, fat sparing in solid mass, and BCLC stage were potential biomarkers to evaluate the survival with favorable performance and discriminate HCC patients with CR under conventional TACE treatment.

Contrast-enhanced computed tomography (CECT) is commonly used for staging and diagnosing recurrent gastric cancer. Recently, 18F-fluorodeoxyglucose positron emission tomography (18F-FDG PET)/CT gained popularity as a diagnostic tool owing to advantages including dual functional and anatomical imaging, which may facilitate early diagnosis. The diagnostic performance of 18F-FDG PET/CT and CECT has been assessed in several studies but with variable results. Therefore, the present meta-analysis aimed to evaluate the accuracy of 18F-FDG PET/CT and CECT for primary TNM staging and the diagnosis of recurrent gastric cancers. A systematic search of the PubMed Central, Medline, Scopus, Cochrane and Embase databases from inception until January 2020 was performed. The Quality Assessment of Diagnostic Accuracy Study-2 tool was used to determine the quality of the selected studies. Pooled estimates of sensitivity and specificity were calculated. A total of 58 studies comprising 9,997 patients were included. Most studies had a low risk of bias. The sensitivity and specificity for nodal staging of gastric cancer were 49% (95% CI, 37-61%) and 92% (95% CI, 86-96%) for 18F-FDG PET/CT, respectively, and 67% (95% CI, 57-76%) and 86% (95% CI, 81-89%) for CECT, respectively. For metastasis staging, the sensitivity and specificity were 56% (95% CI, 40-71%) and 97% (95% CI, 87-99%) for 18F-FDG PET/CT, respectively, and 59% (95% CI, 41-75%) and 96% (95% CI, 83-99%) for CECT, respectively. For diagnosing cancer recurrence, the pooled sensitivity and specificity were 81% (95% CI, 72-88%) and 83% (95% CI, 74-89%) for 18F-FDG PET/CT, respectively, and 59% (95% CI, 41-75%) and 96% (95% CI, 83-99%) for CECT, respectively. Both 18F-FDG PET/CT and CECT were deemed highly useful for diagnosing recurrent gastric cancer due to their high sensitivities and specificities. However, these techniques cannot be used to exclude or confirm the presence of lymph node metastases or recurrent gastric cancer tumors, but can be used for the confirmation of distal metastasis.

Objective To discuss the application value of QCT in diagnosing spontaneous lumbar vertebral compression frac-ture and to calculate the best diagnosis threshold value of female and male of different age groups.Methods Mineral density measurement software and body model of Siemens CT were used to measure the bone mineral density of normal old crowds over 60 years old and crowds with spontaneous lumbar vertebral compression fracture of local region.The bone mineral density data were calculated out for comparative analysis.ROC curves were separately drawn according to the statistical data.The best diagnosis cut-point of men and women at different ages were calculated according to youden index principle.Results Bone density of QCT measurement value of the elderly male and female in the northern region of Chongqing decreased evidently with aging.The bone density of the male at different ages were all greater than the female, and the difference had significant difference ( P <0.05). QCT values of local male and female with spontaneous lumbar vertebral compression fracture at the age levels of 60~69, 70~79, over 80 were all lower than that of the normal old male and female without fracture and of the same age level, and the difference had statistical significance ( P <0.05).The best diagnosis threshold of lumbar vertebra bone density QCT of male and female pa-tients with spontaneous lumbar vertebral compression fracture of different age levels in the northern region of Chongqing were:the male:60~69, 70 ~79, over 80 were separately 109.750 mg/cm3 (95%CI: 73.19, 120.05), 72.983 mg/cm3 (95%CI:71.041, 118.082), 76.867 mg/cm3 (95%CI: 76.312, 82.733); the female: 60 ~69, 70 ~79, over 80 were separately 78.017 mg/cm3(95%CI:65.283, 95.545), 49.900 mg/cm3(95%CI:43.138, 75.900), 40.633 mg/cm3(95%CI:31.382, 65.931) .Conclusion QCT has a relatively high accuracy and sensitivity to the measurement of spontaneous lumbar vertebral compression fracture occurred among old people, so it has a good clinical application value on diagnosing and preventing spontane-ous lumbar vertebral compression fracture occurred among old people.
Objective To investigate the clinical significance of not matching in cranial MRI DWI-FLAIR sequence in patients with a-cute cerebral ischemic stroke. Methods 32 patients with acute ischemic stroke from May 2015 to December 2015 in our hospital were included as the research object. All patients were diagnosed by imaging methods and clinical symptoms as acute ischemic stroke. According to the time of pa-tients with stroke incidence and the changes DWI-FLAIR sequence signal,these patients were divided into the different group,0~4. 5 h group, 4. 5~6. 0 h flair positive group and 4. 5~6. 0 h flair and negative group. The sensitivity and specificity were observed in the different phase with the DWI-FLAIR not matching. At the same time,we compared the effect of thrombolytic therapy and evaluated the application value of DWI-FLAIR not matching in guiding the thrombolytic therapy. Results The sensitivity of acute ischemic brain after stroke onset in 0~3 h,0~4. 5 h groups DWI-FLAIR not matching was 67. 1%,87. 5% and the specificity was 40. 6%,74. 5%,the positive predictive value of 77. 9%,87. 0% and the negative predictive value was 76. 9%,43. 5%. The effect of thrombolytic therapy in patients with negative thrombolysis DWI-FLAIR again pass rate was significantly higher than that of DWI-FLAIR positive group,the difference has statistical significance( P ﹤0. 05). NIHSS and Mrs scores of DWI-FLAIR negative group after thrombolysis were significantly lower than DWI-FLAIR positive group,with statistical signifi-cance( P ﹤0. 05). Conclusion Acute ischemic stroke patients outfit transcranial magnetic MRI,DWI-FLAIR mismatch of in guiding the dif-ferent time of onset of thrombolytic therapy in patients with is of great significance. After the onset of 4. 5~6h,patients with negative flair are still of intravenous thrombolytic therapy. DWI-FLAIR can be an objective image as index to determine the onset time range.
