Intelligent stimuli-responsive fluorescence materials are extremely pivotal for fabricating luminescent turn-on switching in solid-state photonic integration technology,but it remains a challenging objective for typical 3-dimensional(3D)perovskite ***,by fine-tuning the accumulation modes of metal halide components to dynamically control the carrier characteristics,a novel triple-mode photoluminescence(PL)switching was realized in 0D metal halide through stepwise single-crystal to single-crystal(SC-SC)***,a family of 0D hybrid antimony halides was designed to exhibit three distinct types of PL performance including nonluminescent[Ph_(3)EtP]_(2)Sb_(2)Cl_(8)(1),yellowemissive[Ph3EtP]2SbCl5·EtOH(2),and red-emissive[Ph_(3)EtP]_(2)SbCl_(5)(3).Upon stimulus of ethanol,1 was successfully converted to 2 through SC-SC transformation with enhanced PL quantum yield from~0%to 91.50%acting as“turn-on”luminescent ***,reversible SC-SC and luminescence transformation between 2 and 3 can be also achieved in the ethanol impregnation-heating process as luminescence vapochromism *** a consequence,a new triple-model turn-on and coloradjustable luminescent switching of off-onI-onII was realized in 0D hybrid ***,wide advanced applications were also achieved in anti-counterfeiting,information security,and optical logic *** novel photon engineering strategy is expected to deepen the understanding of dynamic PL switching mechanism and guide development of new smart luminescence materials in cutting-edge optical switchable device.

AIM： TO investigate the aberrant methylation of CHFR promoter in human gastric cancer （GC） and its impact on the expression of CHFR mRNA and protein, as well as its correlation with clinical and histological features of human GC. METHODS： Methylation-specific polymerase chain reaction （MSPCR） was used to detect the methylation status of CHFR promoter in 20 primary GC samples and paired normal gastric mucosa. The CHFR mRNA and protein expressions were investigated both by RT-PCR and by Western blotting. The CHFR protein expression in 39 GC samples was immunohistochemically examined. RESULTS： The DNA methylation of the CHFR gene was found in 9 of the 20 GC samples （45%） and the down-regulation of CHFR mRNA and protein was significantly associated with the methylation status of the CHFR gene （P = 0.006）. In 20 samples of corresponding non-neoplastic mucosa, no DNA methylation of the CHFR gene was detected. The CHFR gene methylation in poorly differentiated GC samples was significantly higher than that in well-differentiated GC samples （P = 0.014）. Moreover, the negative CHFR protein expression rate in paraffin-embedded GC samples was 55.07% （38/69）, the positive rate in poorly differentiated GC samples was 36.73% （18/49）, which was significantly lower than 65.00% （13/20） in well-differentiated GC samples （X^2 = 4.586, P = 0.032）. CONCLUSION： Aberrant methylation of the CHFR gene may be involved in the carcinogenesis and development of GC, and is the predominant cause of down-regulation or loss of CHFR mRNA or protein expression. As aberrant methylation of CHFR promoter is correlated with tumor differentiation, it may help to predict the prognosis of GC and CHFR may become a novel target of gene therapy for GC in the future.
