The aim of this study was to investigate the effects of telemonitored exercise rehabilitation on patients with coronary heart disease (CHD) in China. Ninety-six patients with stable CHD were included and analyzed (48 in telemonitored group and 48 in control group). All patients received routine follow-up, and patients in telemonitored group participated in smartphone-based telemonitored cardiac rehabilitation. Patients' demographic information, medical history, diagnosis and treatment of CHD, and laboratory results were collected. The difference of cardiopulmonary exercise testing (CPET), blood test, and echocardiographic parameters; exercise habits; control rate of blood lipid and blood glucose; and incidence of adverse events between the two groups during 6 months of follow-up was analyzed. After intervention, the subjects in the telemonitored group performed significantly better in VO 2peak , exercise compliance, and some other parameters than those in the control group. Telemonitored exercise rehabilitation is an effective rehabilitation mode for CHD patients in China.

Since Dec 2019, China has experienced an outbreak caused by a novel coronavirus, 2019-nCoV. A travel ban was implemented for Wuhan, Hubei on Jan 23 to slow down the outbreak. We found a significant positive correlation between population influx from Wuhan and confirmed cases in other cities across China (R 2 = 0.85, P < 0.001), especially cities in Hubei (R 2 = 0.88, P < 0.001). Removing the travel restriction would have increased 118% (91%-172%) of the overall cases for the coming week, and a travel ban taken three days or a week earlier would have reduced 47% (26%-58%) and 83% (78%-89%) of the early cases. We would expect a 61% (48%-92%) increase of overall cumulative cases without any restrictions on returning residents, and 11% (8%-16%) increase if the travel ban stays in place for Hubei. Cities from Yangtze River Delta, Pearl River Delta, and Capital Economic Circle regions are at higher risk.

We propose and experimentally demonstrate a series of L n slot photonic crystal (PhC) microcavities, which operate as refractive index (RI) gas sensors. The cavities are simply composed of a silicon slab triangular photonic crystal with n holes replaced by a slot, which do not require sophisticated design or high fabrication resolution. With the increase in n, the quality factor of the cavity exponentially increases, which is explained by the envelope of electric field approaching a Gaussian profile. An L 9 slot PhC microcavity with a quality factor exceeding 30 000, sensitivity of 421 nm per RI unit (RIU), and detection limit down to 1 Â 10 À5 RIU was experimentally demonstrated. The performance of the device is comparable with other fine-tuned PhC microcavity structures. Due to its simple structure and high fabrication tolerance, it could have wide applications in optical sensors.
