[Systematic review and pharmacoeconomic evaluation of Qizhi Weitong Granules in treatment of functional dyspepsia].

This study aims to investigate the efficacy, safety, and cost-effecctiveness of Qizhi Weitong Granules in the treatment of functional dyspepsia. Specifically, two commonly used clinical protocols for the treatment of functional dyspepsia were selected: Qizhi Weitong Granules+Mosapride vs Mosapride alone(control). Meta-analysis of previous clinical studies was performed to examine the efficacy and safety, and pharmacoeconomic evaluation was carried out according to the results of the Meta-analysis. The cost-effectiveness analysis was carried out to elucidated the incremental cost-effectiveness ratio(ICER), and the sensitivity was analyzed with tornado dia-gram and Monte Carlo simulation. The willingness-to-pay threshold of patients for functional dyspepsia was investigated and compared with the ICER to evaluate whether Qizhi Weitong Granules was cost-effective. The result showed that the effective rate of Qizhi Weitong Granules combined with Mosapride in the treatment of functional dyspepsia was 95.49%, which was higher than that of Mosapride alone(73.30%)(OR=8.52, 95%CI[4.36, 16.64])(P<0.000 1). The two groups showed no significant difference in safety. The price of Qizhi Weitong Granules+Mosapride was higher than that of Mosapride alone. The ICER was 640.29 CNY, 1 506.67 CNY lower than the willingness-to-pay threshold. The sensitivity analysis showed that the analysis results were relatively stable. Thus, Qizhi Weitong Granules+Mosapride is safe, effective, and economical in the treatment of functional dyspepsia, which should be further promoted in clinical settings.

Antidelaminating, Thermally Stable, and Cost-Effective Flexible Kapton Platforms for Nitrate Sensors, Mercury Aptasensors, Protein Sensors, and p-Type Organic Thin-Film Transistors.

The inkjet printing of metal electrodes on polymer films is a desirable manufacturing process due to its simplicity but is limited by the lack of thermal stability and serious delaminating flaws in various aqueous and organic solutions. Kapton, adopted worldwide due to its superior thermal durability, allows the high-temperature sintering of nanoparticle-based metal inks. By carefully selecting inks (Ag and Au) and Kapton substrates (Kapton HN films with a thickness of 135 µm and a thermal resistance of up to 400 °C) with optimal printing parameters and simplified post-treatments (sintering), outstanding film integrity, thermal stability, and antidelaminating features were obtained in both aqueous and organic solutions without any pretreatment strategy (surface modification). These films were applied in four novel devices: a solid-state ion-selective (IS) nitrate (NO3-) sensor, a single-stranded DNA (ssDNA)-based mercury (Hg2+) aptasensor, a low-cost protein printed circuit board (PCB) sensor, and a long-lasting organic thin-film transistor (OTFT). The IS NO3- sensor displayed a linear sensitivity range between 10-4.5 and 10-1 M (r2 = 0.9912), with a limit of detection of 2 ppm for NO3-. The Hg2+ sensor exhibited a linear correlation (r2 = 0.8806) between the change in the transfer resistance (RCT) and the increasing concentration of Hg2+. The protein PCB sensor provided a label-free method for protein detection. Finally, the OTFT demonstrated stable performance, with mobility values in the linear (µlin) and saturation (µsat) regimes of 0.0083 ± 0.0026 and 0.0237 ± 0.0079 cm2 V-1 S-1, respectively, and a threshold voltage (Vth) of -6.75 ± 3.89 V.
