In this study , 4116 traditional Chinese medicine ( TCM ) prescriptions of 994 outpatients of gastric
cancer from the Jiangsu Provincial Hospital of Traditional Chinese Medicine were analyzed with the use of Clinical Research Information Sharing System and the data mining method of scale-free networks . The core drugs and compatibility were visually displayed on diagrams which revealed the characteristics of gastric cancer treatment with TCM prescriptions in this hospital with high credibility . This method has certain meaning and value for the study of TCM prescriptions .

Objective To investigate the diagnostic value of quantitative energy spectrum CT and multi-parameter magnetic resonance imaging(MRI)on epidermal growth factor receptor(EGFR)mutation in lung adenocarcinoma.Methods Clinical data of 93 patients diagnosed with lung adenocarcinoma and EGFR mutation status by pathology in Jingdezhen Hospital of Traditional Chinese Medicine from June 2020 to June 2022 were retrospectively analyzed.They were divided into mutation group(52 cases)and wild-type group(41 cases)according to EGFR mutation status,and all patients were given quantitative spectral CT and MRI examinations.Changes in parameters between two groups were compared.Results CT40kev,CT70kev,spectral curve slope(λHU),effective atomic number and iodine concentration in arterial and venous phases in mutation group were significantly higher than those in wild-type group(P<0.05).Apparent diffusion coefficient(ADC)and true diffusion coefficient(D)of mutant group were significantly higher than those of wild-type group,while volume transport constant(Ktrans)and reflux rate constant(Kep)of mutant group were significantly lower than those of wild-type group(P<0.05).Analysis of receiver operating characteristics curve showed that area under the curve(AUC)value for CT40kev,CT70kev,λHU,effective atomic number,iodine concentration,CT comprehensive parameters,ADC,D,Ktrans,Kep and MRI comprehensive parameters for diagnosing EGFR mutation status in lung adenocarcinoma were 0.615,0.622,0.680,0.715,0.655,0.855,0.899,0.795,0.740,0.751 and 0.968 respectively.There was statistically significant difference in AUC between CT comprehensive parameters and MRI comprehensive parameters(P<0.05).Conclusion Both quantitative energy spectrum CT and multi-parameter MRI have high diagnostic value in the diagnosis of EGFR mutation status of lung adenocarcinoma,but MRI has higher diagnostic value,which is helpful to provide objective basis for accurate assessment of EGFR mutation status.

Objective To analyze diagnostic value of 18F-fluorode-oxyglucose(18F-FDG)positron emission tomography and computed tomography(PET/CT)in elderly patients with colon cancer.Methods A total of 102 patients with colon cancer admitted to Jingdezhen Hospital of Traditional Chinese Medicine from January 2021 to December 2022 were retrospectively selected to analyze the relationship between 18F-FDG PET/CT imaging and clinical features and its diagnostic value.Results The typical 18F-FDG PET/CT imaging of colon cancer was mainly concentrated in ascending colon,transverse colon,descending colon,and sigmoid colon.The glucose metabolism of each part increased,the intestinal wall thickened,and standardized uptake value(SUV)increased.There were statistically significant differences in SUV among colon cancer patients with different vertical thickness of the lesion,gender and lymph node metastasis(P<0.05).SUV was positively correlated with vertical thickness of the lesion and lymph node metastasis(P<0.05).Receiver operating characteristic curve results showed that the area under the curve of 18F-FDG PET/CT for diagnosis of colon cancer lymph node metastasis was 0.993,the sensitivity was 97.2%,and the specificity was 100%.Conclusion 18F-FDG PET/CT for the diagnosis of elderly patients with colon cancer has a high clinical application value.
