High-performance grating-like SERS substrate based on machine learning for ultrasensitive detection of Zexie-Baizhu decoction.

Rapid, universal and accurate identification of chemical composition changes in multi-component traditional Chinese medicine (TCM) decoction is a necessary condition for elucidating the effectiveness and mechanism of pharmacodynamic substances in TCM. In this paper, SERS technology, combined with grating-like SERS substrate and machine learning method, was used to establish an efficient and sensitive method for the detection of TCM decoction. Firstly, the grating-like substrate prepared by magnetron sputtering technology was served as a reliable SERS sensor for the identification of TCM decoction.

Optimization of surface enhanced Raman scattering performance based on Ag nanoparticle-modified vanadium-titanium nanorods with tunable nanogaps.

The combination of new noble metal nanomaterials and surface enhanced Raman scattering (SERS) technology has become a new strategy to solve the problem of low sensitivity in the detection of traditional Chinese medicine. In this work, taking natural cicada wing (C.w.

M × N electrically controlled optofluidic matrix switch.

A completely non-blocking × electrically controlled optofluidic matrix switch that uses a 1×3 optical switch with a V-shaped microchannel as the switching unit is proposed. Its light paths and output ports are selected by a micro-actuator matrix and a control circuit. There are few reports of optofluidic matrix switches.

Comparison of the efficacy and impact of GEMOX and GDP in the treatment of patients with non-Hodgkin's lymphoma.

Purpose: To compare the efficacy and impact of GEMOX and GDP in the treatment of patients with non-Hodgkin's lymphoma (NHL).

Methods: A total of 68 patients with NHL admitted to the hospitals of the authors from February 2013 to April 2016 were equally distributed into the GEMOX Group (treated with Gemcitabine and Oxaliplatin) and the GDP Group (treated with Gemcitabine, Cisplatin, and Dexamethasone), with cycle repetition every 3 weeks. The efficacy was analyzed every two weeks.
