A new strain gradient theory which is based on energy nonlocal model is proposed in this paper, and the theory is applied to investigate the size effects in thin metallic wire torsion, ultra-thin beam bending and micro-indentation of polycrystalline copper. First, an energy nonlocal model is suggested. Second, based on the model, a new strain gradient theory is derived. Third, the new theory is applied to analyze three representative experiments.

We evaluated the efficacy and safety of as-needed tadalafil in a diverse clinical population （with varying patient demographics, disease severity, and comorbid medical conditions） of Asian men with erectile dysfunction （ED）. An integrated analysis of five double-blind, placebo-controlled trials （N = 1 046） was performed. Patients were randomly assigned to receive 10 mg tadalafil （N = 185）, 20 mg tadalafil （N = 510）, or placebo （N = 351）. Efficacy assessments included the International Index of Erectile Function （IIEF）, Sexual Encounter Profile （SEP） diary and Global Assessment Question （GAQ）. Patients receiving 10 mg or 20 mg tadalafil showed significant improvement from baseline-to-end point on the Erectile Function domain of the International Index of Erectile Function （IIEF-EF） domain score in all clinical sub-populations analyzed, compared with patients receiving placebo （P 〈 0.001）. The 10-mg and 20-mg tadalafil groups showed a mean success rate of 64.1% and 70.5% for sexual intercourse attempts （SEP3, successful intercourse）, respectively, compared with 33.4% in the placebo group （P 〈 0.001）, and 85.5% and 85.4% reported improved erections at end point GAQ, respectively, versus 43.5% in the placebo group （P 〈 0.001）. Tadalafil was well tolerated across all groups studied. Headache and back pain were the most frequently reported adverse events. Overall, tadalafil was effective and well tolerated across a diverse clinical spectrum of Asian men with ED.

Aim： To assess the efficacy and safety of tadalafil in comparison to a placebo, when taken on demand for 12 weeks by East/Southeast Asian men with erectile dysfunction （ED）, Methods： This multicenter, randomized, double-blind, parallel group, placebo-controlled study was conducted at 17 centers across East and Southeast Asia between August 2002 and February 2003. Men more than 18 years of age with mild to severe ED of various etiologies were randomized to receive a placebo or 20 mg of tadalafil taken as needed （maximum once daily）. Efficacy assessments included the International Index of Erectile Function, the Sexual Encounter Profile diary and Global Assessment Questions. Results： Tadalafil significantly improved erectile function as compared to the placebo （P 〈 0.001）. At the endpoint, the patients receiving 20 mg of tadalafil reported a greater mean per patient percentage of successful intercourse attempts （Sexual Encounter Profile question 3： 70.9% compared to 33.5% in the placebo） and a greater proportion of improved erections （Global Assessment Question： 86.2% compared to 30.1%）. Most （≥3%） treatment emergent adverse events were mild or moderate. The most common treatment emergent adverse events were headache, back pain, dizziness and dyspepsia. Conclusion： Tadalafil was an effective and well-tolerated treatment for ED in East and Southeast Asian men.

AIM To explore the correlation of metabolomics profiles ofgastric cancer(GC) with its chromosomal instability(CIN) *** Nineteen GC patients were classified as CIN and nonCIN type by The Cancer Genome Atlas Research Group system, based on 409 oncogenes and tumor suppressor genes sequenced. The aqueous metabolites of the GC tumor and its surrounding adjacent healthy tissues were identified through liquid chromatographymass spectrometry. Groups were compared by defining variable importance in projection score of > 1.2, a fold change value or its reciprocal of > 1.2, and a P value of < 0.05 as a significant *** In total,twelve men and seven women were enrolled, with a median age of 66 years(range, 47-87 years). The numbers of gene alterations in the CIN GC group were significantly higher than those in the non-CIN GC(32-218 vs 2-17; P < 0.0005). Compared with the adjacent healthy tissues, GC tumors demonstrated significantly higher aspartic acid, citicoline, glutamic acid, oxidized glutathione, succinyladenosine, and uridine diphosphate-Nacetylglucosamine levels, but significantly lower butyrylcarnitine, glutathione hydroxyhexanoycarnitine, inosinic acid, isovalerylcarnitine, and threonine levels(all P < 0.05). CIN tumors contained significantly higher phosphocholine and uridine 5'-monophosphate levels but significantly lower beta-citryl-L-glutamic acid levels than did non-CIN tumors(all P < 0.05). CIN GC tumors demonstrated additional altered pathways involving alanine, aspartate, and glutamate metabolism, glyoxylate and dicarboxylate metabolism, histidine metabolism, and phenylalanine, tyrosine, and tryptophan *** Metabolomic profiles of GC tumors and the adjacent healthy tissue are distinct, and the CIN status is associated with downstream metabolic alterations in GC.
