Although the age-adjusted incidence of gastric cancer is declining, the absolute number of new cases of gastric cancer is increasing due to population growth and aging. An effective strategy is needed to prevent this deadly cancer. Among the available strategies, screen-and-treat for Helicobacter pylori infection appears to be the best approach to decrease cancer risk; however, implementation of this strategy on the population level requires a systematic approach. The program also must be integrated into national healthcare priorities to allow the limited resources to be most effectively allocated. Implementation will require adoption of an appropriate screening strategy, an efficient delivery system with a timely referral for a positive test, and standardized treatment regimens based on clinical efficacy, side effects, simplicity, duration, and cost. Within the population, there are subpopulations that vary in risk such that a "one size fits all" approach is unlikely to be ideal. Sensitivity analyses will be required to identify whether the programs can be utilized by heterogeneous populations and will likely require adjustments to accommodate the needs of subpopulations.

The traditional sulfonylureas with long half-lives have sustained stimulatory effects on insulin secretion compared to the short-acting insulin secretagogue. In this study, we used the frequently sampled intravenous glucose tolerance test (FSIGT) to evaluate the insulin sensitivity (IS), glucose sensitivity (SG), and acute insulin response after glucose load (AIRg) after 4months treatment with either gliclazide or repaglinide. The design of study was randomizedcrossover. We enrolled 20 patients with new-onset type 2 diabetes (mean age, 49.3 years). Totally three FSIGTs were performed, one before and one after each of the two treatment periods as aforementioned. No significant differences in fasting plasma glucose, insulin, body mass index, blood pressure, glycated hemoglobin, or lipids were noted between the two treatments. After the repaglinide treatment, higher AIRg, lower IS, and lower SG were noted, but they did not reach statistical significance. The disposal index (DI) was also not significantly different between the two treatments. In conclusion, since non-significantly higher DI, AIRg, lower IS and SG were noted after repaglinide treatment, it might be a better treatment for diabetes, relative to gliclazide.

The monolayered intrarenal urothelium covers the renal papilla and ureteropelvic junction (UPJ). In response to increased renal pressure during obstruction or ischemic injuries, intrarenal urothelial cells begin to proliferate and form a multilayered urothelium. Little is known regarding the mechanism and pathophysiological role of urothelium hyperplasia during renal obstruction. In this study, we investigated the expression of interleukin (IL)-33, an IL-1 family cytokine, in kidneys with unilateral ureteral obstruction (UUO)-induced obstructive injury. IL-33 levels in hydronephrotic urine and serum were upregulated 2 days after UUO. The number of ST2-expressing immune cells was increased in the UUO kidney. We found that IL-33 was upregulated in vimentin-positive cells in the cortical and medullar layers and the UPJ stroma. Moreover, IL-33 expression was predominantly induced in multilayered keratin 5- positive urothelial cells in the UPJ. IL-33 was not detected in terminally differentiated superficial umbrella cells expressing uroplakin 3a. In vivo, we confirmed that deficiency of IL33 or its receptor ST2 attenuated UUO-induced hyperplasia of the UPJ urothelium. Deficiency of IL33 attenuated the expression of UUO-induced type 2 inflammatory cytokines and upregulated uroplakins and urothelial differentiation signaling in UPJ tissues. Our results collectively suggest that the IL-33/ST2 axis mediates the activation of innate immune responses and contributes to urothelial hyperplasia by regulating urothelial differentiation in obstructive kidney injury.
