This article showed the work pattern of rehabilitation assessment, and made assessment of a patient who suffered from bilat-eral hemiplegia and pseudobulbar paralysis caused by multiple cerebral apoplexy. Finally, the special characteristics of rehabilitation treat-ment for a patient with bilateral paralysis were summarized.

Objective: To investigate the changes of ambient dose equivalent rate in 99mTcO4- single photon emission computed tomography (SPECT) of the thyroid among patients with hyperthyroidism, so as to provide insights into radiation protection guidance. Methods: Patients with hyperthyroidism who underwent 99mTcO4- SPECT of the thyroid in a tertiary hospital were enrolled. The ambient dose equivalent rate was measured at different time points following 99mTcO4- infection and at sites with different distances from patients' neck, and the effects of time post-injection, distance from patients' neck, 24-hour thyroidal radioiodine uptake and thyroid weight on the ambient dose equivalent rate were examined using a generalized linear mixed model. Results: Totally 100 patients with hyperthyroidism were enrolled, including 24 men and 76 women and with a mean age of (38.5±14.0) years. The generalized linear mixed model was statistically significant (F=6 610.165, P<0.001), and patients' thyroid weight, time post-injection and distance from patients' neck significantly affected the ambient dose equivalent rate (F=57.967, 15 988.574, 11 200.645, all P<0.001), and the ambient dose equivalent rate positively correlated with patients' thyroid weight and negatively correlated with time post-injection and distance from patients' neck. Conclusions The ambient dose equivalent rate is affected by patients' thyroid weight, time post-injection and distance from patients' neck among patients with hyperthyroidism undergoing 99mTcO4- SPECT of the thyroid. Delay in contact with patients or keeping distance from patients may be effective for radiation protection.

This paper studies the vein extraction technique based on the susceptibility weighted imaging (SWI) and introduced an improved self-adaptive threshold method based on the vessel enhancing diffusion. The approach employs the combination indicator of the local gray character, the global gray character and the tubular information of the vein. It first applies the vessel enhancing diffusion filter to enhance the continuity of the vein, increases the detection rate of tiny vein and suppresses the nucleus areas. And then it uses the improved self-adaptive threshold method to extract the vein. The results demonstrate that this approach can solve the problem above and extract the vein from the SWI image accurately.

Objective To prospectively determine the feasibility of high-resolution in vivo MR imaging in the evaluation of esophageal carcinoma invasion at 3.0 T.Methods One hundred and eighteen patients with esophageal carcinoma,proven by the gastroscopic biopsy,were prospectively studied using 3.0 T MR.The esophageal specimens were sectioned transversely to keep consistent in the orientation with the MR images,the histopathological stage was made and the thickness of the tumor on the largest diameter of the slice were measured.The MR images were reviewed in the transverse plane.According to the seventh American joint committee on cancer,the MR stage was made and the tumor's thickness was measured.The MR images and the histopathological slices were matched.The staging diagnostic efficacy of the MR imaging was evaluated with the histopathological results as the standard reference,Kappa test was used to compare the stage of MR imaging with that at the histopathological analysis.Bland-Altman scatterplots were used to compare the thickness of tumor measured on the MR images with that at the histopathological measurement.Results Ninety seven cases(82.2％,97/118) of MR stage were accurately made,including 7 T1a,15 T1b,18 T2,25 T3 and 32 T4a cases,furthermore,14 cases were over staged and 7 cased were underestimated.The MR stage was highly consistent with the histopathological stage (Kappa=0.772).The sensitivity for the staging of high-resolution MR imaging at 3.0 T was 58.3％(7/12) to 100.0％(32/32),the specificity was 95.3％ (82/86) to 98.1％ (104/106),and the accuracy was 91.5％ (108/118) to 96.6％ (114/118),respectively.Bland-Altman scatterplots demonstrated that the discrepancy of the mean thickness between the value obtained by three radiologists respectively and the histopathological analysis were 2.0,2.6 and 2.1 mm,which demonstrated a good consistency.Conclusion High-resolution MR images obtained at 3.0 T can be used to evaluate the depth of carcinoma invasion and provide excellent diagnostic accuracy for preoperative staging.

Objective:To investigate the effect of reverse saphenous nerve neurocutaneous flaps for skin defects of forefoot with the help of the three dimensional computerized tomography angiography(3D-CTA).Methods:From November 2013 to February 2018, 19 patients with anterior foot defects were treated in the Yidu Central Hospital of Weifang. There were 12 males and 7 females. The patients ranged from 16 to 45 years old, with an average age of 29.6 years. Preoperative 3D-CTA examination of the ipsilateral foot was performed to find out the blood vessels in the donor site, to determine the location, course, length of the superficial branch of the medial plantar toe artery and its relationship with the surrounding tissues, and to design the medial saphenous nerve nutrient vessel skin flap for retrograde repair of the skin and soft tissue defect at the front of the foot. Sensitive recovery were evaluated according to Swanson evaluation of clinical effect of peripheral nervous impairment.Results:Preoperative three-dimensional CT angiography showed that the superficial branches of the medial plantar toe artery were detected, and the perforating vessels during the operation were basically consistent according to the result of the examination. The 19 cases of forefeet skin detects were successfully reconstructed with the reverse saphenous nerve neurocutaneous flaps. All patients were followed up with the mean of 8 months. All flaps survived totally without diabrosis and swelling. The walking and weight-bearing were normal and the blood supply of foot were good. The functional recovery of foot and ankle was excellent in 8 cases, good in 10 cases and middle in 1 case. The sensory recovery of the forefoot: S4 5 feet, S3 10 feet, S2 4 feet; R4 3 feet, R3 9 feet, R2 7 feet.Conclusions:Preoperative 3D-CTA examination can confirm the anatomy of the superficial branch of the medial toe base artery in the donor site and guide the design of the medial saphenous nerve nutrient vessel flap for retrograde repair of skin and soft tissue defects of the distal foot. The blood supply is reliable, the wound is small and the effect is satisfactory.
