More and more studies indicate that type 2 diabetes mellitus (T2DM) is an independent risk factor of the cognitive impairment. It is showed that factors such as diabetic vascular complications and inherenrt metabolism impairment, affect the cognitive functions of the diabetics, and poorly controlled blood sugar and insulin resistant may also play a role in it.

Objective To investigate the cognitive impairment of middle-aged patients with type 2 diabetes mellitus(T2DM). Methods Wechsler adult intelligence scale-Chinese revised edition (WATS-RC) was used as the tool to examine the cognitive function of middle-aged patients with T2DM and the healthy controls in 51 cases. The t-test was used to compare the differences in score between patients and the control group. The patients were divided into two groups with or without cognitive dysfunction. The logistic regression analysis was made for all the variables to confirm risk factors for the cognitive dysfunction in diabetes. Results The WAITS-RC scores of digit-symbol coding test and block design test were much lower(P<0.05) in diabetes versus control group. The other tests showed no significant difference. The cognitive function was negatively correlated with HbA_1>c and HOMA-IR by logistic regression analysis. Conclusions For middle-aged patients with type 2 diabetes, their cognitive functions such as learning ability, analysis and comprehensive capabilities are impaired. The cognitive function is closely related with HbA_1c and HOMA-IR.

Objective To evaluate 18 F deoxyglucose positron emission tomography (FDG PET) in the detection of suspicious recurrence in head and neck cancers , as compared with CT/MRI imaging. Methods Thirty seven patients with clinically suspicious recurrences in head and neck cancers underwent FDG PET, with 34 checked with CT/MRI imaging. The final diagnosis of recurrence were proved by pathology or clinical following up. Results FDG PET detected recurrence successfully in 32 of 37(86.5%) patients with 3 false positives and 2 false negatives. The FDG PET sensitivity, specificity and accuracy in defining local recurrence were 91.7%, 76.9%, 86.5%, respectively; and those of CT/MRI were 68.2%, 75.0%, 61.8%, respectively. Conclusion In comparison with CT/MRI, FDG PET possesses a higher accuracy in detecting recurrence in head and neck cancers.

Objective To differentiate between peri-prosthetic infection and aseptic loosening using quantitative analysis of triphasic bone scintigraphy.Methods Twenty-eight patients (9 males,19 females; mean age 67.5 years,range 49-80 years) with recurrent joint pain after arthroplasty were retrospectively assessed.All patients underwent triphasic bone scintigraphy.ROI of each joint was drawn and the ratios of affected to unaffected side were calculated.The ratios of blood flow phase,blood pool phase,static phase,Creactive protein (CRP) and erythrocyte sedimentation (ESR) were quantitatively analyzed by ROC curve.The final diagnosis was based on microbiological and histological examinations.The optimal cut-off value was chosen based on the ideal sensitivity and specificity.Results Nine patients were diagnosed as septic loosening,17 patients aseptic loosening,1 patient bursitis of hip joint and 1 patient suture reaction.Taking the positive results of blood flow phase or blood pool phase as standard for diagnosing septic loosening,the sensitivity,specificity and accuracy of bone scintigraphy were 7/9,78.9％ (15/19) and 78.6％ (22/28),respectively.The AUC of blood pool phase was 0.942,and the sensitivity and specificity were 8/9 and 78.9％(15/19),respectively,with the optimal cut-off value of 1.40.The AUCs of blood flow ratio and CRP were 0.816 and 0.795,with cut-off values of 1.53 and 1.20,respectively.The AUCs of static phase ratio and ESR were 0.474 and 0.722,respectively,both P＞0.05.Conclusions For the diagnosis of septic loosening,quantitative analysis of triphasic 99Tcm-MDP bone scintigraphy,particularly with the ratio of blood pool phase,is more accurate than qualitative analysis.

Objective To evaluate the curative effect of comprehensive rehabilitative treatment for lumbar intervertebral disc protrusion by using the MRI tests before and after the treatment. Methods Forty patients with lumbar intervertebral disc protrusion were treated by a comprehensive rehabilitative treatment program composed of physical modalities, medications, traction, massage and medical gymnastics, for 30 days. MRI test were performed with all the patients, and comparison of the MRI manifestations before and after the treatment was conducted to evaluate the therapeutic efficacy. Results The clinical effective rate was 82.5%. There was no significant difference between the MRI manifestations, including MRI signal intensity, thickness and degree of the protrusion, anteroposterior and transverse diameter, width of lateral recess, before and after the treatment. Conclusion The comprehensive rehabilitative treatment program used in this study did not significantly decrease the size of lumbar intervertebral disc protrusion, but did relieve or cure the clinical symptoms of the patients.
