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.

0.05). Secondary caries were 6.85% and 9.20% in the group of ART, 6.35% and 8.62% in drill +glass ionomer restoration, 16.9% and 21.50% in amalgam restorations, respectively( P

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 examine the changes of ultrastructural microcirculation of small intestines of portal hypertension (PHT) canines. Methods PHT canine models were established by coarcating a half main portal vein with silk line chronic emboliztion. The ultrastructural changes of small intestine epithelium, mucous membrane and submucosa microcirculation were examined. Results The characteristics of ultrastructural changes of small intestine epithelium, mucous membrane and submucosa microcirculation were as follows: the number of blood vessels was increased and the diameter of them was expanded significantly; the lumen of arteriole was decreased, and the wall was thickened; arteriole collagen fibers were hyperplastic and confused; the lumen of venule was increased, the wall was thinned; basement membrane was damaged; microcirculatary endothelial cell was damaged generally; leukocytes was infiltrated; epithelial cells and basement membrane of intestinal mucosa were damaged; smooth muscle cell nucleus of ileum were deformed. Conclusion Small intestine epithelium, mucous membrane and submucosa microcirculatary ultrastructral showed obvious changes in PHT canines.

Objective To investigate the therapeutic effects of modified Xiaoyao Powder combined with abdominal needling for conducting fire back to its source for the treatment of swallowing dysfunction in Parkinson's disease, and to explore a more effective therapy for swallowing dysfunction in Parkinson's disease. Methods Forty-two Parkinson's disease patients suffering from swallowing dysfunction were divided into treatment group and control group, 21 cases in each group. The patients in both groups received routine swallowing function training. In addition to the training, the treatment group was treated with modified Xiaoyao Powder combined with abdominal needling for conducting fire back to its source, and the control group was given conventional western medicine of Domperidone and Levodopa Benserazide Hydrochloride. After treatment for 3 weeks, we compared the dysphagia scores and effective rate of the two groups. Results (1) All of the patients in the treatment group completed the trial, but 2 cases of the control group dropped out. Therefore, a total of 40 cases completed the trial. (2) The dysphagia scores of the two groups were much improved after treatment (P<0.01 compared with those before treatment) , and the improvement of the treatment group was superior to that of the control group (P < 0.05). (3) After treatment for 3 weeks, the total effective rate of the treatment group was 95.24% and that of the control group was 52 . 63%, and the difference was statistically significant between the two groups(P<0.01).(4) Gastrointestinal reaction occurred in 3 cases(one from the treatment group and 2 from the control group) , but there were no other side effects found in both groups. Conclusion Modified Xiaoyao Powder combined with abdominal needling for conducting fire back to its source is more effective for the treatment of swallowing dysfunction in Parkinson's disease than routine western medicine treatment.

Conclusion Radix Paeoniae Alba should be processed in 48 hours after collection.

OBJECTIVE:To preliminarily study the stability of 3 pieces of Chinese medicinal formula(CMF)after decoction, and provide reference for guaranteeing storage quality of decocted liquid and improving safety of drug use. METHODS:3 represen-tative formulas of Gegen Huangqin Huanglian decoction(A formula),Wuling powder(B formula)and Didang decoction(C for-mula)from Shanghan Zabing Lun were selected,the decocted liquid were stored under ambient temperature(25 ℃)and refrigerat-ed temperature (4 ℃) after decocting by automatic boiling-machine and packing. The microorganism,precipitation,pH and con-tents of total flavonoids,alkaloid,polysaccharide,total protein after 1,7,14,21,28 d were detected. RESULTS:Compared with the first day,contents of total flavonoids,polysaccharide in formula A at ambient temperature group were significantly in-creased on the 28th(P<0.05),content of polysaccharide in refrigerated temperature group was significantly increased(P<0.05). Content of polysaccharide in formula B at ambient temperature group was significantly decreased(P<0.05). The pH and content of total flavonoids in formula C at ambient temperature group and refrigerated temperature group were significantly increased (P<0.05 or P<0.01). Other indexes showed no obvious changes during the trial period. CONCLUSIONS:Under ambient temperature and refrigerated temperature,liquid ingredients of above decocted CMF will change when storing for 4 weeks. It indicates that the storage time of decocted CMF should not be more than 3 weeks.

Objective To summarize the experience of clinical application of combining double suture fixation and resection of partial fat retro-orbicularis oculus in some specially difficult blepharoplasty.Methods During upper blepharoplasty,patients with heaviness and bulkiness in the both upper eyelid and lateral upper orbital region,we combined double suture fixation and resection partial fat retro-orbicularis oculus.First,partial pretarsal bulky fat was resected,and to form skin-orbicularisoculi composite below incision line.And then,some thickened fat retro-orbicularis oculus was resected,which was also named preseptal and retro-orbicularis oculus fat (ROOF).Double suture fixation techniques were applied to form dynamic and physiological double eyelid.Results 146 cases had satisfactory effectiveness,except for 2 cases with secondary operation because of some superficial double eyelid creases,and 1 case had hematoma,and 3 had transient numbness in the lateral supraorbital nerve region.They were satisfied with healthy eyelid skins,concealed incision and non-serious complications followed at 3-24 months postoperatively.Conclusions Combining double suture fixation and resection of partial fat retro-orbicularis oculus would appear to be a useful adjunct to standard blepharoplasty techniques in selected patients.
