Objective To explore the significance of 18fluorodeoxyglucose positron emission tomography(18F?FDG PET/CT)in the etiological diag?nosis of postoperative intestinal obstruction in patients with gastrointestinal cancer. Methods A total of 51 patients with postoperative intestinal ob?struction undergone 18F?FDG PET/CT were enrolled for the study. The images were interpreted by visual and semi?quantitative analysis(maximum standard uptake value,SUVmax). All the cases were confirmed by pathology and clinical follow?up for more than half a year. The sensitivity,specifici?ty and accuracy of 18F?FDG PET/CT for detecting malignant intestinal obstruction were calculated. Results Of the 51 patients,35 cases were con?firmed for malignant intestinal obstruction,and 16 cases were caused by other benign diseases. 18F?FDG PET/CT imaging was positive in 36 cases, and 33 cases were diagnosed as malignant and recurrent intestinal obstruction. Three cases of PET false?positive were peritonitis adhesion and anasto?motic inflammation. Two cases of PET false negative were peritoneal micrometastasis. The SUVmax of malignant lesions was 8.86±4.82,and the SUVmax of benign lesions was 2.05±1.95. The uptake of FDG was significantly higher in malignant intestinal obstruction than in benign intestinal obstruction (t=7.15,P<0.01). The sensitivity,specificity,and accuracy of 18F?FDG PET/CT diagnosis of malignant lesion were 94.3%,81.3%,and 90.2%, respectively. Conclusion The uptake of 18F?FDG in malignant intestinal obstruction was higher than that in benign intestinal obstruction. 18F?FDG PET/CT have a good diagnostic value for the intestinal obstruction of postoperative gastrointestinal cancer.

Objective To explore the characteristic of SPECT/CT imaging of osteolytic lesions with increased bone metabolism and its correlation with CT manifestation. Methods Twenty?one cancer patients with bone metastases underwent 99 Tcm?MDP SPECT/CT imaging ( 13 males, 8 females; age: ( 60. 52 ± 6?85) years) were retrospectively studied. The imaging characteristic of the lesion with high uptake of 99Tcm?MDP was observed and the correlation between the lesion/background ( L/B ) ratio and CT manifestation were analyzed. One?way analysis of variance, two?sample t test and linear correlation analysis were used. Results A total of 111 lesions were found in 21 patients by 99 Tcm?MDP whole?body bone scan, and 125 le?sions were found by SPECT/CT imaging, including 111 lesions with increased bone metabolism and abnor?mal CT manifestation and 14 osteolytic lesions with decreased bone metabolism. In 111 lesions with in?creased bone metabolism, there were 23(20.72%) osteolytic lesions, 54 (48.65%) osteoblastic lesions and 34 (30.63%) mixed lesions. The L/B ratio of osteolytic lesions with increased bone metabolism (11.82± 6?61) was lower than that of osteoblastic lesions (20.03±13.24) and that of mixed lesions (25.42±19.51;F=6.00, P<0?05) . The CT value of osteolytic lesions with increased bone metabolism was higher than that of osteolytic lesions with decreased bone metabolism :(167.53±79.21) HU vs (88.63±49.16) HU; t=3?345, P<0.05. The L/B ratio of lesions with increased bone metabolism was positively correlated to CT val?ue(r=0.404, P<0?05). Conclusions A part of lesions with increased bone metabolism on SPECT/CT im?ages are osteolytic lesions. The L/B ratio of them is positively correlated to CT value. SPECT/CT imaging can reduce missed diagnosis and misdiagnosis.

OBJECTIVE: To explore the effect of different pressure on microcirculation of scar proliferation. METHODS: A total of 60 patients with scar proliferation after burning were collected, including 49 males and 11 females, with averagely aged 37 years. The patients were divided into low pressure (0.67-1.33 kPa), normal pressure (1.33-3.33 kPa) and high pressure (3.33-6.67 kPa) groups by envelope method. Pressure tension bandage was used at 1 week after wound healing and gradually increased, reached expected pressure at days 5-7 and sustained for 6 months. Then the changes of blood perfusion at the scar tissue were measured by laser Doppler perfusion imaging (LDPI). RESULTS: According to the intended processing analysis, all the 60 patients enter the result analysis. There were no significant differences of the scar tissue perfusion of the 3 groups before the therapy. After the therapy, the perfusion was decreased in the low pressure group, but there are no statistical changes compared to before the therapy (P > 0.05), while the perfusion was decreased in the normal pressure and high pressure groups (P < 0.05), which was lower in the high pressure group than the normal pressure group (P < 0.05). When the pressure increased to 3.33-6.67 kPa, the patients feel much more uncomfortable and the swelled signs appear, and 2 patients quit the experiment. CONCLUSIONS: The scar tissue perfusion is decreased obviously when adding the pressure to 3.33 kPa by using tension bandage. Using this method, the pressure should gradually increase to the maximum if patients can bear.

Objective To investigate the relationship between with or without non?alcoholic fatty liver disease(NAFLD) and diabetic retinopathy(DR) in type 2 diabetes mellitus(T2DM)?Methods Clinical and laboratorial data of 517 cases T2DM hospitalized patients were collected,and the patients were divided into two groups according to if the NAFLD was complicated or not?Group A was T2DM with NAFLD and group B was T2DM without NAFLD?The general information and the laboratorial checking results were Compared, then various index were used as the independent variable, DR was used as the dependent variable for Logistic regression analysis?Results (1)In the 517 cases of T2DM patients,the incorporative rate of the NAFLD was 65?7%(349/517)?(2)Compared with group B,the levels of body mass index(BMI),insulin resistance index (HOMA?IR),glutamyltransferase(GGT),alanine aminotransferase(ALT),aspartate aminotransferase(AST), triglyceride(TG),total cholesterol(TC),low?density lipoprotein cholesterol(LDL?C) and uric acid(UA) for group A were significantly increased, while the high?density lipoprotein cholesterol ( HDL?C ) level was significantly decreased?All the differences were statistically significant( P<0?05)?( 3) Logistic analysis showed that the duration of the extension,hypertension,the increasing level of NAFLD,LDL?C were the risk factors of DR?Even though excluded the influence of duration,high blood pressure and LDL?C level,NAFLD was still the risk factor for T2DM complicated by the DR( OR=2?176,95% CI ( 1?354,3?199) )?Conclusion NAFLD and DR are closely related, so early diagnosis and intervention of NAFLD may prevent the occurrence and development of DR.

Incidence of neurodegenerative diseases has been increasing year by year in the current aging society which interferes the living quality of the patients severely. Pathological changes in neurodegenerative diseases appeare in central nervous system CNS . The administration route of drugs to treat neurodegenerative diseases becomes a very important scientific research field. Part of drugs may cross over blood-brain barrier BBB to CNS by oral or injection administration. But most of drugs are distributed in the other tissues and might cause adverse reactions, such as gastrointestinal side-effects and arrhythmia. Moreover, the compliance of the aging patients is poor. They cannot adhere to administer multi-dose drugs for sereral times a day. Nasal drug delivery systems could deliver drugs to brains directly by nasal-brain route, avoiding BBB with high targeting ratio, high drug availability and good patients’ compliance. The review summarizes the major types of neurodegenerative diseases and their current therapeutic methods. The important obstacles for brain-targeted drug delivery, nose-brain routes and the factors influencing nasal absorption are introduced. More importantly, the principal formulations, recent research progress and the unsolved problems of brain-targeted nasal drug delivery systems are also reviewed.
