Objective To assess the diagnostic value of ultrasonographic elastography for identifying suspected malignant thyroid nodules. Methods Fifty-one patients with small single solid thyroid nodule underwent two-dimensional and color power Doppler ultrasonography. The size, shape, boundary, internal echo and halo, calcification of thyroid nodule were observed with two-dimensional ultrasound. Then color Doppler ultrasonography was used to detect blood signal and distribution in the nodules. Longitudinal scanning of elastography was performed, and the findings on elastography were classified into Ⅰ-Ⅴ grades. The ultrasonographic results were compared with pathologic findings. Results Six patients were found with grade Ⅰ and Ⅱ benign lesions;9 with grade Ⅲ ( 6 benign and 3 malignant), 36 with Ⅳ and Ⅴ (2 benign and 34 malignant) lesions on ultrasonographic elastography. Taking the elasticity grade Ⅳ or Ⅴ as malignant standard, the diagnostic sensitivity was 91.89%, specificity was 85.71%, accuracy was 90.20%, while the positive and negative predictive value was 94.44% and 80.00%, respectively. Conclusion Real-time ultrasound elastography is a promising imaging technique that can assist in the differential diagnosis of malignant thyroid small single solid nodule.

Objective To explore the therapeutic effect of traditional Chinese medicine (TCM) on subsolid nodule (SSN). Methods A practical randomized controlled study method, including 254 SSN patients was adopted. The patients were divided into the TCM (102 cases) and follow-up (152 cases) groups. The follow-up group received regular check-ups in accordance with the guidelines, and the TCM group received TCM syndrome differentiation treatment for 24 weeks. The two groups were compared in terms of the changes in their SSN diameter, SSN number, TCM symptom score, and overall therapeutic effect before and after treatment. Adverse reactions and safety indicators were also recorded. Results The TCM group showed a significantly higher effective rate of treatment (16.7%) than the follow-up group (2.6%) (P<0.01). Compared with their condition before treatment, the TCM group showed no significant changes in their SSN diameter and number but presented considerably reduced fatigue, yellow and red urine symptoms, and overall TCM symptom score (P<0.05). The follow-up group exhibited significantly increased diameter and number of SSN (P<0.01). The follow-up group showed the significantly higher increase in SSN diameter after treatment than the TCM group (P<0.05). Moreover, the follow-up group showed significantly higher fatigue, depression, yellow and red urine symptom scores, and overall TCM symptom score than the TCM group (P<0.05 or P<0.01). Conclusion TCM treatment for SSN has a distinct clinical efficacy, reduces the malignant risk of SSN and improves clinical symptoms of SSN patients, and is safe and feasible.

Objective To research the proliferation and apoptosis of glioma stem cells after Gamma knife treatment.Methods The glioma stem cells were cultured in serum-free suspension; real time-PCR was used to detect the CD133 expression; fluorescence staining was employed to observe the expressions of nestin,glial fibrillary acidic protein (GFAP) and [3-tubulin after stem cell differentiation.After 10 Gy Gamma knife treatment for 48 h,the glioma U87 cell and stem cell survival was detected under microscope; after 15 Gy Gamma knife treatments for 8-10 h,immunofluorescent staining was performed to detect the 5-bromodeoxyuridine (BrdU)-positive cells; flow cytometry was employed to compare the changes of cell apoptosis before and after 10 and 15 Gy Gamma knife treatment.Results Under the culture conditions of serum-free medium,glioma stem cells became spherical suspended growth and had proliferation and self-renewal capacity,expressing CD133 and nestin,and containing the ability to differentiate into astrocytes and neural elements.After 10 Gy gamma knife treatments,the cell survival in the glioma stem cells was significantly higher than that in the U87 cells (86±3 vs.22±2,P＜0.05).About 35％ glioma stem cells showed positive BrdU staining before 15 Gy gamma knife treatment and it was about 22％ after treatment with statistical difference (P＜0.05).The apoptosis rate in the glioma stem cells was low; that in cells with 15 Gy gamma knife treatment (0.312±0.011) was significantly higher than that in cells with 10 Gy gamma knife treatment (0.112±0.014,P＜0.05).Conclusions Under the culture conditions of serum-free medium,glioma stem cells can be derived from human glioma tissue.Treatment of gamma knife could inhibit the proliferation of glioma stem cells,causing their apoptosis.As compared with glioma cells,glioma stem cells are not sensitive to gamma knife radiotherapy and radio-resistant.
