OBJECTIVE: To investigate the signal transduction mechanism of curcumin in inhibiting the proliferation of bovine lens epithelial cell (LEC) induced by recombinant human epidermal growth factor (rhEGF). METHODS: There were three groups in this experiment, which were normal control group, untreated group and curcumin-treated group. Proliferation of LEC was induced by rhEGF (50 microg/L). The concentration of intracellular Ca(2+) ([Ca(2+)](i)) in LEC was measured with Fura-2/AM by spectrofluorimetry. The contents of intracellular cAMP and cGMP were assayed by radioimmunoassay. RESULTS: The [Ca(2+)]i in LEC was obviously increased in the untrated group as compared with that in the normal control group (P<0.01), and the [Ca(2+)](i) in LEC in the curcumin-treated group was highest among three groups (P<0.01). The content of intracellular cAMP in LEC was decreased while the content of intracellular cGMP was obviously increased in the untreated group as compared with those in the normal control group (P<0.01). The content of intracellular cAMP in LEC was higher in the curcumin-treated group than that in the untreated group, while the content of intracellular cGMP was lower than that in the untreated group (P<0.01). CONCLUSION: The antiproliferation effects of curcumin on LEC may relate to the regulations of multiple processes of signal transduction.

Objective To investigate the clinical feasibility of contrast?enhanced three dimensional T2WI turbo?spin?echo sequence with short?term inversion recovery and sampling perfection using different flip angle evolutions (3D STIR T2WI SPACE) sequence in the brachial plexus neurography. Methods Thirty two patients were prospectively chosen and performed with brachial plexus plain scanning on a 3.0 T MR scanner by using plain and contrast?enhanced 3D STIR T2WI SPACE sequence. Thirteen of them underwent plain scan, 9 of them underwent contrast?enhanced scan, and 10 of them underwent both plain scan and enhanced scan. The visibility of the brachial plexus were scored and contrast to noise ratio (CNR) were measured by two experienced radiologists. The results between plain and contrast?enhanced imaging were compared by t test. The 10 subjects received both enhance and plain imaging, were performed with paired t test. Results In 32 patients, the visibility score of brachial plexus nerve and CNR were 7.8 ± 1.3 and 24.97±3.41 in the plain scan group, and 13.1±1.7 and 38.49±4.95 in enhanced scan group, respectively. There were statistically significant differences in the two groups(t=-11.72,P<0.01;t=-10.47, P<0.01). In 10 cases with plain and enhanced brachial plexus imaging, the average score of the brachial plexus were 7.4 ± 1.7 and 13.3 ± 1.6, the average CNR were 26.23 ± 4.43 and 38.19 ± 5.03 respectively. There were statistically significant differences (t=- 8.22, P<0.01; t=- 5.64,P<0.01). The score results were analyzed for consistency. Plain images Kappa value was 0.684, which shows moderate consistency and enhanced images Kappa value= 0.822, which shows excelent consistency. Conclusions The contrast?enhanced 3D STIR T2WI SPACE sequences may suppress background tissue signals, which is helpful to display brachial plexus, therefore it is of important value for the early diagnosis of brachial plexus neuropathy.

Objective:To evaluate the effect of canagliflozin on intrarenal fat content and oxygenation in newly-diagnosed type 2 diabetes patients.Methods:Twenty-three newly-diagnosed type 2 diabetes patients were divided into canagliflozin( n=11) and glimepiride control( n=12) groups .Both groups received MRI scanning with Dixon MRI and BOLD MRI sequence to assess patients′ intrarenal fat content, oxygenation level before treatment and 24 weeks after treatment. Fasting blood glucose, glycosylated hemoglobin, blood uric acid, blood lipids, blood pressure, weight, and other metabolic index were also tested before and after treatment. Furthermore, the relationship between body mass index(BMI) and intrarenal fat content and the correlation between changes in intrarenal fat content and improvement in renal hypoxia were analyzed. Results:No significant differences were found in baseline age, body weight, fasting blood glucose, glycosylated hemoglobin, blood lipid, and serum uric acid between the two groups. There was no significant difference in fasting blood glucose, glycosylated hemoglobin, cholesterol(CHO), low-density lipoprotein-cholesterol(LDL-C), and triglycerides(TG) levels in both groups after 12 and 24 weeks of treatment. The decrease in body weight, blood uric acid level, and diastolic blood pressure from baseline in the canagliflozin group was greater than those in the control group( P<0.05). Two groups of patients with type 2 diabetes at baseline had no obvious difference in intrarenal fat content, and the patients′ BMI showed no obvious correlation with degree of intrarenal fat accumulation. Canagliflozin treatment for 24 weeks could reduce intrarenal fat content, which was higher than that of control group. The R2 * values of renal cortex and medulla in the canagliflozin group decreased from baseline by 19.22% and 22.63% respectively( P<0.05), whereas no significant difference was seen in the glimepiride control group. The decrease of intrarenal fat content in the canagliflozin group was related to the improvement of renal cortex and medulla oxygenation. Conclusion:Canagliflozin can reduce intrarenal fat accumulation and improve renal cortical hypoxia in newly diagnosed type 2 diabetes patients with normal renal function.
