Objective To investigate prognostic predictors of long-term survival of patients with cardiac amyloidosis （CA）, and to determine predictive value of high-sensitivity cardiac troponin T （hs-cTnT） in CA patients. Methods We recruited 102 consecutive CA cases and followed these patients for 5 years. We described their clinical characteristics at presentation and used a new, high-sensitivity assay to determine the concentration of cTnT in plasma samples from these patients. Results The patients with poor prognosis showed older age （56 ±12 years vs. 50 ±15 years, P=0.022）, higher incidences of heart failure （36.92%vs. 16.22%, P=0.041）, pericardial effusion （60.00%vs. 35.14%, P=0.023）, greater thickness of interventricular septum （IVS）（15 ±4 mm vs. 13 ±4 mm, P=0.034）, higher level of hs-cTnT （0.186 ±0.249 ng/mL vs. 0.044 ±0.055 ng/mL, P=0.001） and higher NT-proBNP （N-terminal pro-B-type natriuretic pep-tide） levels （11,742 ± 10,464 pg/mL vs. 6,031 ± 7,458 pg/mL, P=0.006）. At multivariate Cox regression analysis, heart failure （HR：1.78, 95%CI：1.09-2.92, P=0.021）, greater wall thickness of IVS （HR：1.44, 95%CI：1.04-3.01, P=0.0375） and higher hs-cTnT level （HR：6.16, 95%CI：2.20-17.24, P=0.001） at enrollment emerged as independent predictors of all-cause mortality. Conclusions We showed that hs-cTnT is associated with a very ominous prognosis, and it is also the strongest predictor of all-cause mortality in multivariate analysis. Examination of hs-cTnT concentrations provides valuable prognostic information concerning long-term outcomes.

Electroless copper plating process of N, N, N′, N′-tetrakis (2-hydroxypropyl)ethylenediamine(THPED) chelating agent was researched comprehensively. The results indicate that plating rate decreases with the 3H2O has a bad effect on deposits quality, but 2, 2′-dipyridyl and PEG make deposits quality improve greatly. Low concentration of 2-mercaptobenzothiozole (2-MBT) increases plating rate and improves deposits quality, but decreases plating rate and worsens deposits quality when 2-MBT reaches 5 mg/L. The optimal conditions of this electroless MBT are 16.8 g/L, 16.0 mL/L, 13.3 g/L, 0.5 g/L, 5.0 mg/L and 2.0 mg/L, respectively, pH value is 12.75,bath temperature is 30 ℃. Plating rate reaches 9.54 μm/h plating for 30 min in the bath. The SEM images demonstrate that the surface of copper film is smooth and the crystal is fine.

Sequence-activated chemiluminescence(CL) technique offers a unique approach to detecting specific biomolecules or cellular events with high sensitivity and spatial resolution. The fundamental principle behind sequence-activated CL probes involves tailoring highly-controllable CL signals in response to specific sequences or events of interest, thus enabling high-contrast signals under complex physiological conditions. This sequential activation could be triggered by enzymes, reactive oxygen species(ROS), biothiols or changes in the microenvironment. These unique sequence-activated CL probes bestow several advantages, including minimal background, deep-tissue penetration, and the ability of non-invasive or minimally invasive detection. The sequence-activated CL techniques represent a significant advancement in molecular imaging and diagnostics. In this mini-review, we focus on the latest developments in sequential CL probes, addressing the technical challenges and discussing the future trajectory by harnessing CL signaling and molecular recognition.

With the development of quantum computing technology, quantum public-key cryptography is gradually becoming an alternative to the existing classical public-key cryptography. This paper designs a quantum trapdoor one-way function via EPR pairs and quantum measurements. Based on this, a new quantum public-key cryptosystem is presented, which offers forward security,and can resist the chosen-plaintext attack and chosen-ciphertext attack. Compared with the existing quantum public-key cryptos,eavesdropping can be automatically detected in this new quantum public-key cryptosystem under a necessary condition, which is also detailed in the paper.
