DTC is a common type of endocrine carcinoma.There are various imaging modalities for the diagnosis of DTC,such as ultrasound,contrast enhanced CT,MRI,131I whole body scintigraphy.18F-FDG PET/CT is widely used in many kinds of malignant tumors.This review concentrates on the clinical application of 18F-FDG PET/CT in DTC.

blood stasis vessel obstruction syndrome among all cases,occupying 40.91%,31.31% and 13.89% respectively;the groups of damp-heat of liver and gall and stagnation of the liver Qi and deficiency of the spleen have very active replication of virus;however,insufficiency of both the spleen and the kidney are in lower-lever replication.[Conclusion]There is significant correlation between damp-heat of liver and gall and stagnation of the liver Qi and deficiency of the spleen and activity replication of HBV.In Chronic Hepatitis B,the dampness has a close relation with HBV.

Objective To analyze the image characteristics and clinical value of 18F-FDG PET/CT in patients with extranodal nasal type natural killer/T-cell lymphoma (ENKTL).Methods From January 2012 to March 2016,20 ENKTL patients (12 males,8 females;median age 53 years) who underwent whole-body 18F-FDG PET/CT were enrolled in this retrospective study.Eleven patients were newly diagnosed,and 9 were previously treated.Clinical data were collected for histopathology and bone marrow biopsy,laboratory results,PET/CT and radiological findings such as CT or MRI.The final diagnosis was based on histopathology and immunohistochemistry.Mann-Whitney u test was used to compare the SUVmax of newly diagnosed patients and patients with recurrence or disease progression after therapy.Spearman correlation analysis was used to explore the relation between diameter of tumor-invaded lymph nodes and SUVmax.Results ENKTL could be found in all parts of the body,but more frequently in the nasal cavity,nasopharynx and skin.All lesions showed high uptake of FDG on PET/CT.The SUVmax of newly diagnosed patients was significantly higher than that of patients (n=7) with recurrence or disease progression:6.5(4.3,10.4) vs 5.4(3.4,8.9);u=6 853.500,z=-2.039,P＜0.05).The diameter of tumor-invaded lymph nodes showed weakly positive correlation with SUVmax(rs =0.290,P＜0.01),suggesting that invasion of ENKTL might not be accurately evaluated by the size of lymph nodes.The staging by PET/CT was concordant with clinical final staging in 11 newly diagnosed patients,while the staging by CT or MRI was only correct in 6 patients.Conclusions PET/CT is superior to conventional imaging modalities in diagnosis and staging for patients with ENKTL.Since some lesions might be found in the limbs,limbs should be included in the scan field.

Objective To observe the preventive effects of 2.5% sodium bicarbonate solution on the patients who had upper respiratory tract infection caused by fungal with hormone treatment.Methods 36 patients of systemic lupus erythematosus,polymyositis/dermatomyositis were randomly divided into two groups:observer group with glucocorticoid treatment and using 2.5% sodium bicarbonate solution to clean the mouth,and control group only with glucocorticoid treatment.After 7 days,we observed the rate of fungal infection of the two groups.Results There was significant diffience on the rate of fungal infection between observer group and control group(P0.05).Conclusion Using 2.5% sodium bicarbonate solution to clean the mouth can effectively prevent the patients who has upper respiratory tract infection caused by fungal with hormone treatment and decrease the rate of fungal infection.

Objective To compare anesthetic effect and safety of general anesthesia and combined spinal and epidural anesthesia used in autonomic nervous hyperresponsive surgery for patients with paraplegia.Methods 26 paraplegic patients were randomly divided into two groups-control group and treatment group from February 2011 to November,2015,each with 13 cases.The control group used general anesthesia,while the treatment group used combined spinal and epidural anesthesia,to observe onset time,duration,intraoperative hemodynamic changes and complications,Complications,length of stay and cost,Days and costs of hospitalization,satisfaction of patients and their families,of anesthesia in two groups.Results The dosage of narcotics and the onset time of the treatment group were better than that of the control group.The difference between the two groups was significant,and had statistical significance (P＜0.05) Two groups of patients after surgery,diastolic blood pressure,systolic blood pressure and heart rate were lower in the treatment group than in the control group,and had statistically significant difference (P＜0.05);The postoperative complications of the treatment group were significantly better than those of the control group,and had statistically significant difference (P＜0.05);There were statistically significant differences in postoperative pain degree between the two groups (P＜0.05);Two groups of patients in hospital days,hospital costs,satisfaction rate had statistically significant difference,Have statistical significance (P＜0.05).Conclusion In autonomic nervous hyperresponsive surgery for patients with paraplegia,anesthetic effect and safety of combined spinal and epidural anesthesia is significantly better than that of general anesthesia,featured by the rapid onset of action,long duration,fewer complications,strong safety and patients' great satisfaction.It is worth generalizing and applying clinically.

Objective To investigate the value of gastrointestinal tract preparation with oral racean?isodamine tablets and isotonic mannitol in 18 F?FDG PET/CT imaging. Methods From July to September 2013, 129 patients with confirmed or suspected tumors who were referred for 18 F?FDG PET/CT imaging were divided into 2 groups. In the study group (30 males, 37 females, age (53.4±13.9) years), raceanisodam?ine tablets (10 mg) and 1 000-1 200 ml isotonic mannitol solution (2.5%) were orally taken at 10 min after in?jection of 18F?FDG;while in the control group (37 males, 25 females, age (60.0±12.8) years), 1 000-1 200 ml water was given. Mann?Whitney u test was used to compare the difference between the 2 groups in the filling degree of gastrointestinal lumen, delineation of tube wall, physiological uptake, matching degree of PET and CT images, delineation of mesentery, and the influence of gastrointestinal uptake on the identification of ab?dominal and pelvic lesions. χ2 test was used to compare the difference between the 2 groups in the uptake pattern of gastrointestinal tract and the incidence of side effects. Spearman correlation analysis was used to study the correlation between gastrointestinal lumen filling and PET/CT image matching. Results The gas?trointestinal lumen filling, delineation of tube wall, PET/CT image matching in the stomach, small intestine and colon (z: -5.096 to -2.665, all P<0.01),and delineation of mesentery (z=-2.781,P<0.01) were better in the study group than those in the control group. The filling degree of gastrointestinal lumen correla?ted with the corresponding PET/CT image matching (rs:0.521, 0.755, 0.239, all P<0.01). The physio?logical uptake of small intestine and colon was significantly higher in control group than that in the study group( z=-4.131, -3.095, both P<0.01) . But uptake in the stomach between the 2 groups was not signifi?cantly different(z=-0.776, P>0.05). There was statistically significant difference in the uptake pattern of small intestine between the two groups(χ2=12.884, P<0.01) , but not in the stomach and colon (χ2=0.559, 1.083,both P>0.05). The incidence of transient diarrhea (20?9%, 14/67) was higher in the study group than that in the control group (4.8%, 3/62;χ2=7.256,P<0.01). Conclusions The abdominal PET/CT image quality is improved by gastrointestinal preparation with oral raceanisodamine tablets (10 mg) and 1 000-1 200 ml isoton?ic mannitol solution (2.5%).
