Objective To evaluate the performance of ultrasonography (US) for the preoperative staging of papillary thyroid carcinoma (PTC). Methods One hundred and twenty-one patients with cytologically proven PTC were prospectively collected. Patients were recruited at the Chinese Academy of Medical Sciences Cancer Hospital from January 2014 to November 2014. Preoperative US was performed for the evaluation of primary tumor size, extrathyroidal extension and neck lymph node metastasis according to the 6th UICC TNM staging system. Results The sensitivity, specificity, positive predictive value (PPV) and negative predicative value (NPV) of US in predicting extrathyroidal extension were 89.6%(60/67), 72.2%(39/54), 80.0%(60/75), 84.8%(39/46), respectively. The accuracies of preoperative US for T1, T2, T3, T4 stage were 75.0%(36/48), 100%(1/1), 81.9%(59/72), 0, respectively. The sensitivity, specificity, PPV, and NPV of US in predicting neck lymph node metastasis were 47.5%(29/61), 90.0%(54/60), 82.9%(29/35), 62.8%(54/86), respectively. Conclusion Ultrasonography is a feasible tool for preoperative staging of PTC and is helpful for accurate prediction of extrathyroidal tumor extension and lateral neck lymph node metastasis.

Objective To analyze the sonographic ifndings of large adrenal cortical adenoma. Methods The sonographic characteristics of thirteen cases of large adrenal cortical adenoma (diameter≥4.0 cm) which were diagnosed by surgery from January 2006 to August 2012 were retrospectively reviewed. Results In all cases, the adenomas had distinct margins. The mean size of lesions was (5.5±1.6) cm, ranging from 4.0 cm to 8.8 cm. On echotexture, three lesions were homogeneous and the remaining ten lesions were heterogeneous. In addition, seven contained hypoechoic nodules and hyperechoic septum, three had anechoic area, three had extremely hyperechoic area with acoustic shadow, and two had patchy hyperechoic area. On Doppler, most lesions had no lfow signal. Conclusions Large adrenal adenomas have complete capsule and heterogeneous internal echoes with septum, calciifcation, necrosis and hemorrhages. These characteristics are less frequently seen incommon adrenal adenoma, therefore may be helpful in recognition of large adrenal adenoma in clinical practice.

The present study aims to predict the action targets of antidepressant active ingredients of Xiaoyaosan to understand the "multi-components, multi-targets and multi-pathways" mechanism. Using network pharmacology, the reported antidepressant active ingredients in Xiaoyaosan (saikosaponin A, saikosaponin C, saikosaponin D, ferulic acid, Z-ligustilide, atractylenolide I, atractylenolide II, atractylenolide III, paeoniflorin, albiflorin, liquiritin, glycyrrhizic acid and pachymic acid), were used to predict the targets of main active ingredients of Xiaoyaosan according to reversed pharmacophore matching method. The prediction was made via screening of the antidepressive drug targets approved by FDA in the DrugBank database and annotating the information of targets with the aid of MAS 3.0 biological molecular function software. The Cytoscape software was used to construct the Xiaoyaosan ingredients-targets-pathways network. The network analysis indicates that the active ingredients in Xiaoyaosan involve 25 targets in the energy metabolism-immune-signal transmutation relevant biological processes. The antidepressant effect of Xiaoyaosan reflects the features of traditional Chinese medicine in multi-components, multi-targets and multi-pathways. This research provides a scientific basis for elucidation of the antidepressant pharmacological mechanism of Xiaoyaosan.

Objective: To investigate the effect of motivational interviewing on functional exercise in postoperative breast cancer patients. Methods: A total of 128 postoperative breast cancer patients admitted to our hospital from March 2016 to October 2017 were selected and divided into control group and observation group before and after motivational interviewing. The control group was given routine functional exercises guidance, while the observation group was given motivational interviewing on the basis of the control group. The self-efficacy and functional exercise compliance of the two groups were evaluated before intervention, on the day of discharge, and 3 months after discharge. The shoulder joint mobility of the two groups was evaluated 3 months after discharge. Results: Repeated measures analysis of variance showed that there were statistically significant difference between the control group and the observation group in C-SUPPH (F_intervention=5.608, P=0.020) and Postoperative Functional Exercise Compliance Scale for Breast Cancer(F_intervention=6.776, P=0.010); The shoulder joint mobility of the observation group was superior to the control group at 3 months after discharge (U=2.128, P=0.033). Conclusion Motivational interviewing can improve self-efficacy and functional exercise compliance of postoperative breast cancer patients, and promote the recovery of shoulder joint activity function.

Purpose: This study aimed to describe the clinical response to five-step systematic therapy (FSST) in the management of plugged ducts and mastitis. FSST was a comprehensive milk stasis dredging treatment, which contained five steps to make the milk out of the plugged duct. Methods: This retrospective study included 922 breastfeeding women, 714 with plugged ducts, and 208 with mastitis who received FSST from June to September 2017. The breast pain score, swelling degree, and range of breast induration were recorded pre-FSST and post-FSST. Results: After a single FSST, pain score and swelling degree were significantly improved (both p < .001) in all cases. After FSST, the mean breast pain relief score was 1.69 ± 0.70, whereas the mean swelling fade away degree was 1.61 ± 0.62. In the subgroup analysis, pain score and swelling degree were significantly improved (both p < .001) in the plugged ducts group and the mastitis group. The score of pain relief in the plugged ducts group was less than that in the mastitis group (1.63 ± 0.68 vs. 1.91 ± 0.70, t = 5.30; p < .001), whereas improvement of swelling fade away was greater in the plugged ducts group than the mastitis group (1.65 ± 0.64 vs. 1.48 ± 0.56, t = 3.49; p = .001). The composition ratio of changes in induration range between the two groups was statistically different (Pearson χ2 = 137.87, p < .001), of which more obvious improvement in the plugged ducts group than the mastitis group (χ2 = 25.65, p < .001). Conclusion FSST can relieve pain, reduce breast swelling and range of induration, and for plugged ducts or mastitis varied degree differently.

Objective To compare the diagnostic efficiency of the thyroid imaging reporting and data system (TIRADS), the Bethesda system for reporting thyroid cytopathology(BSRTC) and BRAFV600E detection, and their combined use in the differentiation between benign and malignant thyroid nodules. Methods One hundred and twenty eight patients with 128 thyroid nodules who were scheduled for ultrasound-guided fine-needle aspiration biopsy (FNAB) were recruited for the study. All of them underwent ultrasound, fine-needle aspiration cytology(FNAC) examination, and BRAFV600E detection. TIRADS and BSRTC systems were adopted to judge the ultrasound and FNAC results. The receiver operating characteristic curve was established to assess the diagnostic value of each method. Results The sensitivity, specificity, and AUC of TIRADS were 74. 3%, 84. 5%, and 0. 794, respectively. BSRTC had higher specificity(98. 3%) and equal sensitivity compared to TIRADS. The sensitivity, specificity, and AUC of BRAFV600E detection were the highest ones among the three methods. Combinations of different methods could increase the diagnostic sensitivity and accuracy. The combination of FNAC and BRAFV600E detection significantly increased the diagnostic efficiency(AUC=0. 984), with sensitivity 98. 6% and specificity 98. 3%. Conclusions The diagnostic value of BRAFV600E detection in the differentiation of benign and malignant thyroid nodules is better than both TIRADS and BSRTC, and the combination of FNAC and BRAFV600E detection reaches the best diagnostic efficiency.

Objective To study the characteristics of fluid intake and central venous pressure (CVP) within 4 days after birth in very low birth weight (VLBW) premature infants complicated with bronchopulmonary dysplasia (BPD).Method From February 2015 to March 2019,VLBW preterm infants without serious complications were enrolled in two hospitals.Their CVP were measured every 4 ～ 6 hours after birth.They were assigned into BPD group and non-BPD group,and the fluid intake and CVP within 4 days after birth were compared between these two groups.Result A total of 45 VLBW preterm infants were included,including 17 in the BPD group and 28 in the non-BPD group.The fluid intake in the BPD group showed no significant difference with the non-BPD group within 4 days after birth (P ＞ 0.05).No significant correlation existed between the mean liquid intake and the mean CVP in 1 ～ 4 days after birth (r =0.093,P=0.542).From day1 to day4,the CVPs of the BPD group were (3.97 ± 0.68),(4.49 ± 0.75),(4.55 ± 0.66),(4.02 ± 1.05) cmH2O,and the non-BPD group were (3.66 ± 1.09),(3.96 ±0.76),(3.81 ± 0.69),(3.91 ± 0.65) cmH2O.The differences between the BPD group and the nonBPD group were statistically significant (P ＜ 0.05).The CVP of the BPD group was increasing from day 2 to day 3 (P ＜ 0.05).Conclusion VLBW premature infants complicated with BPD may have higher CVP at the early stage of life,which may not be related with the fluid intake.

Objective To explore the effects of transcutaneous electrical acupoint stimulation (TEAS) on upper limbs function in chronic stroke patients. Methods From March, 2016 to May, 2018, 53 patients were randomly divided into control group (n = 27) and research group (n = 26). All the patients received conventional rehabilitation, and the research group received additional intervention of TEAS, for six weeks. They were assessed with Manual Muscle Test (MMT) on upper limbs, modified Ashworth Scale (MAS), Fugl-Meyer Assessment-upper extremities (FMA-UE), Hand Motor Status Scale and modified Barthel Index (MBI) before, at the end of 6-week treatment and twelve weeks after treatment. Results There was no significant difference in all the scores between two groups at the end of 6-week treatment (t < 1.511, P > 0.05). The scores of MMT of wrist dorsal extension, FMA-UE and MBI were better in the research group than in the control group twelve weeks after end of treatment (t > 2.312, P < 0.05). Conclusion TEAS may promote the recovery of hands and upper limbs function in chronic stroke patients.
