Under the background of the deep convergence of China's digital services and manufacturing, it is of great significance to investigate the effects of the convergence of digital services and manufacturing on economic growth and carbon emissions reduction to the application of digital technology in the whole world. This paper constructs a simultaneous equation model and uses three-stage least squares to estimate the effect and mechanism of industrial convergence on economic growth and carbon emissions. The results show that (i) industrial convergence improves the change of total factor productivity (TFP) and the change of technical efficiency, and the reduction of carbon emissions is the main factor driving the growth of TFP and technical efficiency; (ii) industrial convergence and carbon emissions show a significant U-shaped relationship; (iii) the heterogeneity analysis shows that the convergence of capital-intensive, technology-intensive and labor-intensive manufacturing with digital services will help to improve the growth of TFP, it can inhibit carbon emissions first and then promote it. Therefore, the government should take targeted measures to promote industrial convergence of digital services and manufacturing according to the economic development and industry characteristics, so as to give full play to its positive role in economic growth and emissions reduction.

Objectives: Pre-stroke statin use reduces stroke severity and improves functional outcomes; however, whether low-dose statins as a primary preventive measure have similar effects on the Chinese population remains unclear. Methods: Consecutive cases of ischaemic stroke between May 2011 and January 2017 were retrospectively analysed. The primary endpoints were stroke severity on admission and functional outcomes at 90 days. The secondary endpoints were factors related to lower stroke severity on admission. Propensity score matching and logistic regression analyses were performed. Results: Of the 1878 patients, 6.4% and 23.8% were pre-stroke statin users before and after propensity matching, respectively, reducing the National Institutes of Health Stroke Scale (NIHSS) score on admission from 5 (2–9) to 3 (2–4) (P < 0.001). Patients receiving pretreatment with low-dose statins tended to have a better mRS distribution (median mRS score 2 [1–3] vs. 3 [2–4], P = 0.007) and a higher likelihood of favourable functional outcomes (FFOs) at 90 days (61 [65.6%] vs. 151 [50.8%], P = 0.005). The logistic regression analysis showed that low-dose statins taken before stroke (odds ratio [OR] = 0.15, 95% confidence interval [CI] = 0.08–0.27, P < 0.001) and being male (OR = 0.81, 95% CI = 0.66–0.99, P = 0.035) were related to a lower stroke severity on admission but not among patients with atrial fibrillation (OR = 1.65, 95% CI = 1.12–2.44, P = 0.012) or elevated white blood cell (WBC) counts (OR = 1.12, 95% CI = 1.08–1.17, P < 0.001). Conclusions: Pretreatment with low-dose statins reduced initial stroke severity, improved functional outcomes at 90 days and was independently associated with a lower stroke severity on admission among Chinese patients.
