Objective To retrospectively evaluate interobserver variability between radiologists by using lexicon of the Thyroid Imaging Reporting and Data System ( TI-RADS ) to classify lesions on ultrasonography and retrospectively determine the positive predictive value ( PPV) of each TI-RADS level. Methods Five radiologists retrospectively reviewed 188 consecutive thyroid nodules with known pathologic diagnosis of 172 patients from June,2016 to November,2016. Each observer described each lesion with TI-RADS terminology and final TI-RADS level were assigned by adding the points from all categories. Cohen κ statistic was used to assessed the interobserver variability for each ultrasonographic ( US ) descriptors and final TI-RADS level. PPV for all TI-RADS levels were determined for all readers combined. Results For each US descriptor,composition,echogenicity,shape,margin,echogenic foci,their κ were 0.743 (0.713－0.772),0.418 (0.319－0.517),0.468 (0.389－0.547),0.397 (0.291－0.503) and 0.566 (0.514－0.617) respectively ( data in parentheses are 95% confidential intervals). The κ for TI-RADS level was 0.782 (0.749 －0.81). PPV for TI-RADS level 1 to 5 were 0(0/8),0(0/23),14.3% (4/28),29.7%(11/37) and 85.7% (78/91). Conclusions Interobserver agreement with the TI-RADS terminology is substantial for composition, moderate for echogenicity, shape and echogenic foci, fair for margin. Interobserver agreement is substantial for TI-RADS level. Consequently different understanding in US images has little influence in patient management,justifying the use of ACR-TIRADS in clinical practice.

Objective To investigate the immune disorder in elderly patients with severe ischemic stroke and to explore whether a new type of diabetes-specific enteral nutrition formula can regulate the immune function of these patients.Methods In the randomized controlled prospective study,90 patients aged 60-80 years with acute ischemic stroke and NIHSS score more than 10 and dysphagia were randomized to two groups:receiving a new type(Group A) of,versus traditional(Group B) diabetes-specific enteral nutrition.30 Patients aged 60-80 years with acute ischemic stroke and NIHSS score ≥10 without dysphagia were enrolled as control(Group C).The immune function was observed,and the nutritional status and immunological function were compared between two different enteral nutrition groups at 7 days of treatment.Results After 7 day follow-up,the serum lipid stats significantly ameliorated in group A.An obvious suppression of immune state was observed in severe acute ischemic patients at onset of 7 days.At day 7 of treatment,the percentage of CD3+ T cells in group A was(69.25±9.93)％ after treatment vs.(63.36±7.79)％ at baseline(P＜0.001),and CD3 +CD4+T cells was(45.79±9.47)％ after treatment vs.(36.12±9.15)％ at baseline(P＜0.001),as well as CD4+/CD8+ cells were(2.27±1.40)％ after treatment vs.(1.70±0.82)％ at baseline(P=0.001).At 7 days of treatment,the percentage of CD3+ T cells was higher in group A (69.25 ±9.93) ％ than in group B(63.07± 9.47) ％ (P＜0.001),and the percentage of CD3 + CD4 cells was higher in group A(45.79 ± 9.47) ％ than in group B(41.32 ± 8.89) ％ (P=0.024).Conclusions Enteral nutrition preparations can provide sufficient energy support in the acute ischemic stroke.Immunosuppressive state exists in patients with acute phase of severe ischemic stroke.The new type of diabetic enteral nutrition formula can significantly improve immunosuppressive state in patients with acute severe stroke.

OBJECTIVE: To assess the effect of one-stage repair of secondary nasolabial deformity and nasal septoplasty for cleft patients on nasal airway resistance (NAR). METHOD: Using active anterior rhinomanometry, NAR was measured in eighteen patients with cleft lip and palate who suffered form one-stage repair of secondary nasolabial deformity and septoplasty at per-and-post operation. RESULT: NAR was (0.664 +/- 0.200) kPa/(s x L) before operation, (0.304 +/- 0.180) kPa/(s x L) six months after operation, and (0.396 +/- 0.250) kPa/(s x L) twelve months after operation respectively. The differences are statistically significant (P < 0.01) between the NAR before and after operation. Subjective impression score of nasal patency was 7.5 +/- 1.5 before-operation, 2.1 +/- 2.0 after-operation for six months, 3.0 +/- 2.4 after-operation for twelve months. There are significant differences in the subjective impression score of nasal patency as well (P < 0.01). CONCLUSION Correction of septal deformities play a very important role in the operation for secondary nasolabial deformity, which can decrease NAR and improve the subjective impression of nasal patency.

OBJECTIVE: To explore the feasibility of low-temperature radiofrequency ablation for the treatment of tongue base cyst. METHOD: Low-temperature radiofrequency ablation was used to treat 14 patients with the cyst of tongue base under general anesthesia with endotracheal intubation. Operation time, the volume of blood loss and postoperative complications were recorded and the follow-up was taken after surgery. RESULT: The tongue base cysts were totally resected in 14 patients, among which 12 patients only underwent one operation under general anesthesia and two patients received once again under local anesthesia. The procedure took approximately 5-10 min and the volume of blood loss during surgery varied from 1-5 ml. Endotracheal catheter was extubated as usual and incision of trachea was not done. The VAS score of foreign pharynx sensation decreased significantly from preoperative 83.1 +/- 11.2 to postoperative 10.3 +/- 3.6 (P < 0.01). There were no significant postoperative haemorrhage, pharyngalgia, dyspnea or other complications. Speech and the motor function of tongue base were not affected. Follow-up survey ranged from 7 months to 3 years and the cure rate was about 92.9% (13/14) as the recurrence occurred only in one out of 14 cases. CONCLUSION Low-temperature radiofrequency ablation is a promising management for the cyst of tongue base with less trauma, complications or recurrence.
