Objective To evaluate the imaging feature of microcarcinoma of thyroid with CT.Methods CT findings of 50 lesions in 47 patients with microcarcinoma of thyroid ( dimeter,0.5 to 1.0 cm) were retrospectively analyzed.All of the patients had pathological diagnosis.Results Of the 50 lesions,38 lesions showed homogeneous low density on non-enhanced CT and various degree of enhancement on postcontrast CT. Thirty-three lesions showed discontinuous edge of the thyroids on non-enhanced CT. The boundary of 30 lesions became unclear on post-contrast CT relative to non-enhanced CT and the extension of low density of lesions decreased. Theshape of 31 lesions were irregular. Fifteen lesions showed calcifications,with granular calcifications in 13 lesions.Ten lesions were complicated with thyroiditis.Conclusions Irregular shape,discontinuous edge of the thyroids,the shrinkage of low density of lesions on post-contrast CT relative to non-enhanced CT,granular calcifications and multiple small lymph node around lesions indicate the diagnosis of microcarcinoma of the thyroid.It should be noted that thyroiditis can cover up microcarcinoma of thyroid.

A total of 3 431 subjects aged 18 years or over from Liaoning province were involved in this study.The prevalence of metabolic syndrome(MS) was 19.50%,being 19.79% in men and 18.44% in women, according to the standard of Chinese Diabetes Society in 2004.Villages had the highest prevalence of MS in women,while cities had the lowest;towns had the highest prevalence of MS in men,while villages had the lowest.The prevalence of MS was increased with both aging and income.The peak of MS is turning to the developing district.

Objective To evaluate the value of annular calcification in CT in the diagnosis and differential diagnosis for benign and malignant thyroid nodules.Methods CT findings of 67 nodules in 67 patients pathologically diagnosed with annular calcifications were retrospectively analyzed to identify 49 benign nodules and 18 malignant nodules.The interior or boundaries of annular calcification before and after contrast-enhancement were compared,and the degree of enhancements of both interior annular calcification and thyroid tissues were observed.After contrast-enhancement,the numbers of lesions showing clearer boundaries and higher degree of enhancement were summarized.Statistic analysis was conducted by using x2 test.Results Among 67 nodules with annular calcifications,clearer boundaries after contrast-enhancement were observed in 61.2％ (30/49) benign nodules and 16.7％ (3/18) malignant nodules,showing significant statistical difference (x2 =10.457,P ＜ 0.05).The sensitivity and specificity of clearer edge after contrast-enhancement for benign nodules were 61.2％ (30/49) and 83.3％ (15/18) respectively.Higher degree of enhancement were observed in 16.3％ (8/49) in benign nodules and 0(0/18) malignant nodules,showing no significant statistical difference (x2 =3.337,P ＞ 0.05).The sensitivity and specificity of higher degree of enhancement for benign nodules were 16.3％ (8/49) and 100.0％ (18/18) respectively.The combination of clearer boundaries and higher degree of enhancement after contrast-enhancement was observed in 77.6％ (38/49) benign nodules and 16.7％ (3/18) malignant nodules,showing significant statistical difference (x2 =20.549,P ＜ 0.05).Meanwhile,the sensitivity and specificity of such combination for benign nodules were 77.6％ (38/49) and 83.3％ (15/18) respectively.Conclusions CT is important in the diagnosis of thyroid nodules with annular calcification.Clearer boundary after contrast-enhancement and its combination with higher degree of enhancement are helpful for the diagnosis of benign nodules.Boundaries that similar to or more obscure than that of plain scan indicate malignant nodules.

Background and purpose: Epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) is of advantage in treating non-small cell lung cancer (NSCLC) patients with EGFR mutations. However, their clinical effects vary individually. This study aimed to evaluate whether the EGFR ligand, plasma transforming growth factor α (TGF-α), could act as a predictor for the EGFR-TKI treatment e?ciency in NSCLC patients with EGFR mutations and the association between TGF-α and prognosis in these patients. Methods: Seventy-five NSCLC patients with EGFR gene positive mutation were included in the current study from May 2012 to Jul. 2014 in Ruikang Hospital A?liated to Guangxi University of Chinese Medicine. Plasma TGF-α was measured using enzyme-linked immunosorbent assay (ELISA) in all of the patients before EGFR-TKI treatment. The radiographic evaluation was performed 2 months after the therapy. The association between TGF-α and clinical outcome and its prediction e?ciency were determined, followed by the further analysis of the association between TGF-α and overall survival (OS) as well as progression-free survival (PFS). Results: After EGFR-TKI treatment, there were 20 patients with partial response (PR), 25 with stable disease (SD) and 30 with progression disease (PD) in all 75 NSCLC patients harboring EGFR positive mutation. The disease control (DC) rate reached 60%. Patients in PD group presented statistically significant higher plasma TGF-αthan patients in the DC group (P<0.01). Multivariate COX model indicated that smoking status, lymph node metastasis and plasma TGF-α levels were independent risk factors for prognosis in these patients. The ROC analysis revealed that baseline plasma TGF-α showed good prediction e?ciency [area under the curve (AUC)=0.926] and the cut-off point of TGF-α was 16.75 pg/mL. Higher level of TGF-α (≥16.75 pg/mL) was associated with smoking history, clinical stage, lymph node metastasis and clinical outcome of the patients (P<0.05). In comparison to patients with low TGF-α, the patients with high TGF-α concentration presented significantly reduced median OS and PFS (log-rank P<0.05). Conclusion: Higher plasma TGF-α (≥16.75 pg/mL) had a predictive role in EGFR-TKI resistance and poor prognosis.

Objective To investigate the changes of traditional Chinese medical constitution types with menstrual cycle of sub-health state women, thus to explore the affectability of diseases during menstrual cycle. Methods Sub-health State Questionnaire and Menstruation State Questionnaire established in our previous study were used for the epidemiological survey of 330 women outpatients aged 20-45 years admitted by the disease-preventive department of Tianhe District Hospital of Traditional Chinese Medicine. Results In 330 cases, the cases of sub-health state accounted for 64.5%, in which 21.5%had pure sub-health state without any chronic diseases, and 43.0% had sub-health state together with some diseases. The diseases of hyperplasia of mammary glands, vaginitis, cervical spondylosis, hyperlipemia, chronic appendagitis, and uterus myoma had higher morbidity rate in order. At premenstrual phase, constitution types of Qi stagnation, damp heat, and blood stasis had the higher incidences; at menstruation phase, Qi stagnation, blood stasis, and damp heat had the higher incidences; at postmenstrual phase, yang deficiency, Qi deficiency, and damp heat had the higher incidences. Most of the sub-health state women had the complex constitution types, accounting for 93%. Conclusion Traditional Chinese medical constitution types are correlated with menstral cycle of sub-health state women, and show some effects on the affectability and progress of diseases. The investigation results of dynamic changes and the distribution of traditional Chinese medical constitution types during menstrual cycle will supply some evidence for the prevention and treatment of irregular menstruation and sub-health state of the women with Chinese medine.

Objective To assess the value of CT hyperenhancement sign in diagnosis and differential diagnosis of benign and malignant thyroid nodules.Methods CT findings of 2926 nodules in 1676 patients were retrospectively analyzed,among which 2174 nodules were benign and 752 nodules were malignant.All the patients had pathological diagnosis.The degrees of enhancement were divided into hyperenhancement and iso/hypoenhancement.The distribution of hyperenhancement in benign and malignant nodules were summarized.The sensitivity,specificity,positive and negative predictive value and accuracy of hyperenhancement for benign nodules and adenomatoid nodules were observed.Results Hyperenhancement was more common in benign nodules than in malignant nodules (10.3％ vs 0.7％,x2 =70.259,P ＜ 0.05),and its sensitivity,specificity,positive and negative predictive value and accuracy was 9.8％,99.5％,98.2％,27.6％ and 32.8％,respectively.Hyperenhancement was more common in adenomatoid nodules than in nonadenomatoid benign nodules (67.4％ vs 6.1％,x2 =525.025,P ＜ 0.05),and its sensitivity,specificity,positive and negative predictive value and accuracy was 67.4％,93.9％,41.6％,97.8％ and 92.3％,respectively.Conclusion Hyperenhancement sign is an important sign which can effectively differentiate benign nodules from malignant nodules,and adenomatoid nodules from nonadenomatoid benign nodules,and it is helpful for diagnosis of benign nodules and adenomatoid nodules.

Objective To investigate the diagnostic value of CT signs of ipsilateral central lymph node metastasis (ICLNM) in single papillary thyroid carcinoma (PTC) by multivariate regression analysis.Methods The CT data of 302 single PTC with diameter ＞1.0 cm confirmed by operation and pathology were retrospectively analyzed.The optimal thresholds of lymph node metastasis diameter were obtained by receiver operating characteristic (ROC) curve analysis.And multivariate regression analysis was used to analyze the relation between lymph node size,degree of enhancement,calcification or cystic degeneration,central turbidity,positive lateral cervical lymph nodes and the ICLNM positivity.Results In 302 PTC,the proportion of ICLNM positive and negative was 63.6％ (192/302) and 36.4％ (110/302),respectively.According to the ROC curve,with the increase of lymph node diameter,the sensitivity of diagnosing lymph node metastasis decreased and the specificity increased.When the threshold was 0.4 cm,Youden index was the largest (0.358),and the sensitivity and specificity was 50.5％ and 80.3％,respectively.Multivariate analysis showed that the diameter≥0.4 cm,high enhancement,central turbidity and lateral cervical lymph nodes positivity were the independent risk factors of ICLNM,and the OR values were 4.189[95％ CI (2.037-8.617)],3.875 [(95％ CI (1.561-9.617)],4.054[(95％CI (2.230-7.371)] and 8.735 [(95％ CI (1.093-69.831)],respectively.Calcification or cystic degeneration was not statistically significant in ICLNM.Conclusions The diameter ≥0.4 cm,high enhancement,central turbidity and lateral cervical lymph nodes positivity are the independent risk factors of ICLNM.Although calcification or cystic degeneration is not the independent risk factor,it has high accuracy for ICLNM positivity.The accurate identification of these signs can help surgeons to take a more thorough surgical treatment and has great significance to reduce postoperative recurrence.
