Objective To explore the feasibility of individualized low rate contrast agent injection scheme combined with low tube voltage scanning in CTA imaging of low body mass index(BMI) subjects' head and neck. Methods Ninety cases of head and neck CTA examination of low BMI subjects in our department from January 2020 to November 2020 were selected for the study, and randomly divided into three groups with 30 cases in each group. Group A applied 80 kV scanning, low flow rate and low total volume injection scheme. Group B applied 120 kV scanning, high flow rate, low total volume injection scheme. Group C applied 120 kV scanning, high flow rate and high total volume injection scheme. The injection velocity, injection volume, radiation dose length product (DLP) among three groups were compared. In each image of the aortic arch, common carotid artery, basilar artery and the central part of sternocleidomastoid, the CT value, the signal-to-noise ratio and contrast-to-noise ratio were evaluated. Two experienced radiologists performed image quality evaluation. Results Image quality in group A and B by subjective evaluation got 4 points out of 4, and group C got 3 points out of 4, and there was statistical difference between group A, B and C in subjective evaluation of image quality (P<0.05). The injection velocity and DLP of contrast agent in group A were 27.75% and 47.10% lower than those in group B and C, respectively. The total amount of contrast agent injection in groups A and B was decreased by 39.87% compared with group C, with statistical difference (P<0.05). The corresponding CT values of each vessel in group A were slightly higher than those in group B and C, and there were statistically significant differences in the Objective parameters of other vessels except for aortic arch (P<0.05). Conclusion The combination of individualized low flow rate and precise contrast agent injection scheme with low tube voltage scanning technology for low BMI subject could not only reduce the injection rate and risk of contrast agent, but also reduce radiation dose, on the premise of meeting the diagnostic requirements of image quality. It is worthy of popularization and application.

Objective To investigate the diagnostic causes of Bethesda Ⅲ (AUS/FLUS) thyroid nodules and the value of subcategories in predicting risk of malignancy (ROM) of thyroid nodules. Methods The data of 356 cases of Bethesda Ⅲ nodules were collected, and the causes, ROM and subcategories were summarized. Results In 97 resected specimens, 72 were diagnosed as papillary thyroid carcinoma (PTC), and the ROM of Bethesda Ⅲ was 74.2%. The main factors affecting the diagnosis of PTC were small lesions, few puncture cells, atypical nuclear features and lack of papillary structure. Secondary factors included significant interstitial fibrosis or calcification, unqualified smear, improper fixation, poor staining and lack of cytological diagnosis experience.

The differences between high-risk group and low/medium-risk group were statistically significant (P＜0.05). Conclusion The diagnosis of Bethesda Ⅲ is subjective and empirical in some degree, and the risk related subcategories of Bethesda Ⅲ nodules is helpful to achieve better ROM stratification and improve the clinical management of the disease.

Objective To explore the effect of rhubarb acupoint application combined with rectal finger force stimulation in patients with constipation after stroke. Methods In this study, 90 patients with post-stroke constipation admitted to our hospital from January 2019 to December 2019 were randomly divided into group A (rhubarb acupoint application group), group B (rectal finger force stimulation group) and group C (rhubarb acupoint application combined with rectal finger force stimulation group), 30 cases in each group. The effective rates of constipation treatment in the three groups were recorded, and the Wexner constipation scoring system was used to evaluate the degree of constipation before and after treatment among three groups. Results The Wexner scores of the three groups before and after treatment were analyzed by self-paired non-parametric rank sum test, and the differences were statistically significant (all P<0.05). The difference among the three groups before and after treatment using Kruskal-Wallis H test was statistically significant (H=26.211, P<0.05), and after pairwise comparison, the differences were statistically significant (P<0.05). It was worth noting that the Wexner score of group C dropped significantly after treatment. The effective rate of treatment in group C was significantly higher that those in the other two groups. The result showed effective rate of group C (90%)＞ group B (80%)＞group A (53.5%), the difference was statistically significant (P<0.05). Conclusion Compared with the single treatment of rhubarb acupoint application or rectal finger force stimulation, the combined treatment had better efficacy, which reduced incidence of constipation and improved the quality of life of patients.
