Objective:The purpose of the study was to identify the best sequence of therapy beginning with a tyrosine kinase inhibitor(TKI)as the first-line therapy for patients with metastatic renal cell carcinoma(mRCC)in terms of overall survival(OS),progression-free survival(PFS),and rates of discontinuation and adverse effects during the treatment ***:This is a retrospective,nationwide multicenter study of patients with mRCC after diagnosis at 10 different tertiary medical centers in Korea from January 1992 to December *** focused on patients at either“favorable”or“intermediate”risk according to the International mRCC Database Consortium criteria,and they were followed up(median 335 days).Finally,a total of 1409 patients were selected as the study *** generated a Cox proportional hazard model adjusted for covariates,and the different therapy schemes were statistically tested in terms of OS as well as *** addition,frequencies of discontinuation and adverse events were compared among the therapy ***:Of the primary patterns of treatment sequences(24 sequences),“sunitinib epazopanib”and“sunitinibeeverolimuseimmunotherapy”showed the most beneficial results in both OS and PFS with significantly lower hazards than“sunitinib”,which is the most commonly treated agent in *** that the“TKIeTKI”structure showed relatively higher discontinuation rates with higher adverse effects,the overall beneficial sequence would be“sunitinibeeverolimuseimmunotherapy”.Conclusion:Among several sequential therapy starting with TKIs,“sunitinibeeverolimuse immunotherapy”was found to be the best scheme for mRCC patients with“favorable”or“intermediate”risks.

In this work, tribological characteristics of thin films composed of entangled carbon nanotubes(CNTs) were investigated. The surface roughness of CNT thin films fabricated via a dip‐coating process was controlled by squeezing during the process with an applied normal force ranging from 0 to 5 kgf. Raman spectra and scanning electron microscopy(SEM) images of the thin films were obtained to estimate the influence of the squeezing process on the crystallinity of the CNTs. The analysis revealed that squeezing could reduce surface roughness, while preserving the crystallinity of the CNTs. Moreover, the surface energy of the cover glass used to press the CNT thin film was found to be the critical factor controlling surface roughness. A micro‐tribometer and macro‐tribometer were used to assess the tribological characteristics of the CNT thin film. The results of the tribotest exhibited a correlation between the friction coefficient and surface roughness. Dramatic changes in friction coefficient could be observed in the micro‐tribotest, while changes in friction coefficient in the macro‐tribotest were not significant.

The coronavirus disease 2019(COVID-19) is a global pandemic that has heavily impacted not only the health sector, but also the economic sector in *** countries have projected a negative economic impact, and the effect on micro-, small-, and medium-sized enterprises(MSMEs) is predicted to be significantly *** study estimated the regional resistance of MSME sales revenues and identified the regional economic factors that affect resistance by analyzing South Korea, a country with one of the lowest economic impact projections from COVID-19. Resistance was estimated by comparing sales revenues and changes in resistance observed during the early COVID-19 period to those recorded in the same weeks(weeks 6 to 9) of 2019. The factors that affect regional resistance were determined by conducting robust regression and spatial regression analyses. The results show that the number of confirmed COVID-19 cases, a direct risk factor, is negatively related to regional resilience, while diversity is positively related to regional resistance. To improve the regional resistance against uncertain events, this study recommends increased diversity among regional industrial structures to reduce the duration of the early shock of an unexpected adverse event.

Objective： To investigate the antiproliferative effects of zinc-citrate compound on hormone refractory prostate cancer （HRPC）. Methods： HRPC cell line （DU145） and normal prostate cell line （RWPE-1） were treated with zinc, citrate and zinc-citrate compound at different time intervals and concentrations to investigate the effect of zinc-citrate compound. Mitochondrial （m）-aconitase activity was determined using aconitase assay. DNA laddering analysis was performed to investigate apoptosis of DU145 cells. Molecular mechanism of apoptosis was investigated by Western blot analysis of P53, P21w^fl, Bcl-2, Bcl-xL and Bax, and also caspase-3 activity analysis. Results： Treatment with zinc-citrate compound resulted in a time- and dose-dependent decrease in cell number of DU145 cells in comparison with RWPE-1. M-aconitase activity was significantly decreased. DNA laddering analysis indicated apoptosis of DU145 cells. Zinc-citrate compound increased the expression of P21wall and P53, and reduced the expression of Bcl-2 and Bcl-xL proteins but induced the expression of Bax protein. Zinc-citrate compound induced apoptosis of DU145 cells by activation of the caspase-3 pathway. Conclusion： Zinc-citrate compound can induce apoptotic cell death in DU145, by caspase-3 activation through up-regulation of apoptotic proteins and down-regulation of antiapoptotic proteins.

Objective To establish and evaluate the efficacy of the simple assessment system of oocyte maturity. Methods A total of 251 couples were enrolled in this study and female patients were divided into two groups. In group Ⅰ, oocytes were inseminated at 6 h after ovum pick-up. In group Ⅱ, oocyte maturity was rapidly categorized by simple assessment system. Mature oocytes were inseminated at 3-4 h after ovum pick-up when oocyte-corona complexes （OCC） exhibited clear thick ring-like halo （RLH） and expanded cumulus cells （CC） or 5-6 h when OCC exhibited RLH and a few clumped and/or dark CC, respectively. Intermediate oocytes were inseminated at 7-8 h when RLH was not found around the OCC and CC were compacted and clumped and/or dark. Results Normal fertilization rate was higher in group Ⅱ （76.5%） than that in group Ⅰ （58.0%）（P〈0.001）. However, abnormal fertilization rate was higher in group Ⅰ（11.3%） than that in group 11 （3.6%）（P〈0.001）. The cleavage （82.6% vs 90.0%）, chemical pregnancy （4. 8% vs 3.9%）, twin pregnancy （6. 7% vs 3.9%） and implantation rate （8.4% vs 10.6%） had no statistically differences between group I and Ⅱ. Rate of clinical and singleton pregnancy was higher in groupⅡ （35.3% and 31.4%） than those in group Ⅰ （24.8% and 18.2%）（P〈0.05）. Conclusion This simple assessment system is useful and effective for evaluation and categorization of the oocyte maturity with better reproductive outcomes.
