Objective To evaluate the short-term effect of CT-guided interstitial implantation of 125I seeds for metastatic lung carcinoma. Methods A total of 82 patients with 126 metastatic lung tumors were treated with CT-guided percutaneous interstitial implantation of 125I seeds at a dose of 80 Gy. Six months after the treatment, the change of tumor volume was observed by using CT scan. The patients were followed up for 2 years. Results The mean radioactive dose was (159.3?34.5) Gy, and the median dose was (118.6?33.2) Gy. Six months after the treatment, CT scan showed a CR of 25.4% (32/126), PR 64.3% (81/126), NC 6.3% (8/126), PD 4.0% (5/126), and CR+PR 89.7% (113/126). Twelve patients showed pneumothorax and 41 had hemoptysis. During the follow-up, 11 patients (6 cases of malignant fibrous histiotoma, 3 cases of lung cancer, 1 rectal carcinoma, and 1 liver carcinoma) died within 8-12 months after the surgery. Fifteen patients (4 cases of malignant fibrous histiotoma, 4 lung cancer, 4 ovarian cancer, 2 multiple myeloma, and 1 uterine leiomyosarcoma) died within 13-24 months after the implantation. The 1-and 2-year survival rates were 86.6% (71/82) and 68.3% (56/82) respectively. Conclusion CT-guided percutaneous interstitial implantation of 125I seeds is effective for lung metastatic carcinoma.

ObjectiveTo investigate the objective characteristics of tongue manifestations in patients with coronary heart disease (CHD). MethodsA total of 315 participants with CHD were recruited in the CHD group, and 211 healthy participants who underwent physical examination were recruited as the healthy control group. In addition, according to the common comorbidities (primary hypertension, carotid atherosclerosis, type 2 diabetes mellitus, fatty liver, hyperlipidaemia, heart failure, and cerebral infarction) in 315 participants with CHD, each comorbidity was classified into a group of comorbidities with that disease and a group of non-comorbidities. Tongue images were captured using a TFDA-1 tongue diagnostic instrument to characterise the tongue body (TB) and tongue coating (TC), comparing the RGB, HIS, and Lab colour spaces in the chromaticity index (R, red; G, green; B, blue; H, hue; I, intensity; S, saturation; L, lightness; a, red-green axis; b, yellow-blue axis), the tongue coating thickness index (per-All), contrast (CON), angular second moment (ASM), entropy (ENT), and mean (MEAN) in texture metrics. ResultsCompared with the healthy control group, the characteristic indexes of tongue body in CHD group showed lower TB-R, TB-G, TB-B, TB-I, TB-L and higher TB-H, TB-b; and the characteristic indexes of tongue coating in CHD group showed lower TC-R, TC-B and higher TC-CON, TC-MEAN, TC-H, TC-b (P<0.05 or P<0.01). Compared with non-combined primary hypertension group, CHD combined primary hypertension group showed higher per-All, TB-G, TB-L, and lower TB-a, TC-a (P<0.05); compared with the non-combined carotid atherosclerosis group, CHD combined carotid atherosclerosis group showed higher TB-CON, TB-ENT, TB-MEAN, and lower TB-ASM (P<0.05 or P<0.01); compared with the non-combined type 2 diabetes mellitus group, CHD combined type 2 diabetes mellitus group showed lower per-All and higher TB-H (P<0.05 or P<0.01); compared with the non-combined fatty liver group, CHD combined fatty liver group showed higher TB-CON, TB-MEAN, TB-ENT, and lower TB-ASM and TC-S (P<0.05 or P<0.01); compared with the non-combined hyperlipidaemia group, CHD combined hyperlipidaemia group showed lower TB-S and TB-a (P<0.05); compared with non-combined heart failure group, CHD combined heart failure group showed lower TB-R, TB-G, TB-I, TB-L, and higher TB-a (P<0.05 or P<0.01); compared with non-combined cerebral infarction group, CHD combined cerebral infarction group showed higher TC-CON, TC-ENT, TC-MEAN, and lower TC-ASM (P<0.05 or P<0.01). ConclusionCompared to healthy individuals, patients with CHD tend to have darker tongue colours and rougher TC textures. Compared with non-comorbidity participants, those with primary hypertension tended to be lighter tongue colour and thicker tongue coating, those with carotid atherosclerosis had paler tongue body, those with type 2 diabetes mellitus had thinner tongue coating, those with fatty liver disease had paler tongue body and whiter tongue colour, those with hyperlipidaemia and heart failure had paler tongue colour, and those with cerebral infarction had rougher tongue texture.
