Objective To explore the distribution characteristics of TCM syndrome and clinical relevant factors of benign prostatic hyperplasia (BPH).Methods Totally 781 cases of BPH patients were collected. Chi-square test, analysis of rank and inspection were used to detect the distribution characteristics of TCM syndrome. The multiple classification logistic regression was used to analyze related factors.Results BPH 14 kinds of distribution of syndromes were statistically significant (P<0.01). One of the highest incidence is qi deficiency and blood stasis syndrome (24.97%), and lung heat obstruction is the lowest (1.15%). Composite syndromes (529 cases) were more common than single syndrome (252 cases); syndromes of intermingled deficiency and excess (453 cases) were more common than simple excess (169 cases) or deficiency syndromes (159 cases). BPH single syndrome distribution was different in prostate volume, residual urine volume, maximum urine flow rate, and showed no difference in the serum PSA level. 3 logit model was established successfully. It was found that the patients with the features of 50 to 60 years old, the course < 3 years, I-PSS score for 8 to 19 points showed higher positive incidence of excess syndrome than intermingled deficiency and excess syndromes and deficiency syndrome.Conclusion This study reveals the BPH distribution characteristics and clinical related factors, which has guiding significance to improve TCM clinical level.

Objective To prospectively validate the feasibility and usefulness of the thyroid imaging reporting and data system (TI-RADS) suggested by Kwak. Methods According to the TI-RADS published in Radiology by Kwak et al in 2011, the TI-RADS score of 810 thyroid nodules in 415 patients whose pathologic diagnoses were available were categorized . According to TI-RADS and pathologic results, receiver operating characteristic (ROC) curve was plotted, and the probability of malignancy in each category was calculated. Results Eight hundred and ten pathologically proven thyroid nodules included 649 benign and 161 malignant lesions. Among them, 11 nodules were categorized as TI-RADS 2 (all benign nodules);370 nodules were categorized as TI-RADS 3 (368 benign nodules and 2 malignant nodules);150 nodules were categorized as TI-RADS 4a (143 benign nodules and 7 malignant nodules);116 nodules were categorized as TI-RADS 4b (87 benign nodules and 29 malignant nodules); 146 nodules were categorized as TI-RADS 4c (39 benign nodules and 107 malignant nodules);17 nodules were categorized as TI-RADS 5 (1 benign nodules and 16 malignant nodules). The area under the curve of TI-RADS was 0.89, and the probability of malignancy in nodules with a classiifcation of TI-RADS 2, 3, 4a, 4b, 4c and 5 was 0, 0.5%, 4.6%, 25.0%, 73.0%and 94.0%, respectively. Conclusions The TI-RADS suggested by Kwak has great diagnostic value in diagnosing thyroid nodules. The actual probability of malignancy conforms with the theoretical risk of malignancy.
