To analyze the efficacy and influencing factors of Mifepristone combined with estrogen-progesterone sequential therapy (Femoston) in the treatment of incomplete abortion. This retrospective cohort study included 93 patients with incomplete abortion. All patients took 50 mg of Mifepristone 2 times a day for 5 days and then took Femoston once a day (starting with estradiol tablets/2 mg) for 28 days. Without any indication of intrauterine residue by ultrasonic examination was judged to be effective. According to statistical analysis, this study calculated the effective rate and analyzed its influencing factors. A 2-sided value of P < .05 was considered statistically significant. The total response rate of the treatment regimen was 86.67%. body mass index was a significant influencing factor for treatment outcome (OR 0.818, 95% confidence interval 0.668–0.991, P = .041). For patients with incomplete abortion, Mifepristone combined with estrogen-progesterone sequential therapy has a remarkable therapeutic effect. Patients with a lower body mass index may respond much more significantly to this treatment regimen.

The Fe3+/Fe2+redox electrolyte for use in polyaniline/tin oxide (PANI/SnO2) supercapacitors was reported. The influences of redox electrolyte based on different Fe3+/Fe2+ion pair concentrations in 1 mol/L H2SO4solution on the pseudocapacitive behaviors of PANI/SnO2supercapacitor were investigated. The electrochemical properties of the supercapacitor were studied by cyclic voltammetry (CV), galvanostatic charge–discharge (GCD), and electrochemical impedance spectroscopy (EIS) techniques. It is found that the performance of the supercapacitor is the best when the Fe3+/Fe2+concentration is 0.4 mol/L and its initial specific capacitance is 1172 F/g at an applied current density of 1 A/g. The long-term cycling experiment shows good stability with the retention of initial capacitance values of 88% after 2000 galvanostatic cycles. The experimental results testify that using Fe3+/Fe2+redox electrolyte has a good prospect for improving the performances of energy-storage devices.

This paper presents a laterally driven resonant barometric pressure sensor fabricated using SOI-MEMS technology. In this device, pressure under measurement causes a deflection of a pressure-sensitive silicon square diaphragm, which is further translated to stress build up in H style doubly-clamped micro beams, leading to resonant frequency shift. In device fabrication, SOI-MEMS fabrication processes were utilized, where a new modified buffered hydrofluoric acid (BHF) solution was used to remove the buried oxide layer and release the suspended resonant beams. Experimental results recorded a device resolution of 10Pa, a nonlinearity of 0.04% and a temperature coefficient of-0.04% F.S/°C in the range of-40°C to 30°C. The long-term stability error of the proposed device was quantified as 0.05% F.S over the past 3 months.
