The Annual Report on Cardiovascular Health and Diseases in china(2022) intricate landscape of cardiovascular health in china. This section dissects cardiovascular risk factors in china which including hypertension, dyslipidemia, diabetes mellitus, chronic kidney disease, metabolic syndrome and air pollution. Hypertension prevalence has steadily increased in china,with efforts to control it facing challenges in achieving optimal rates, especially in rural areas. Interventions like salt substitutes and intensive blood pressure control show promise but need improvement. Abnormal lipid levels, indicative of dyslipidemia,have risen significantly, posing a risk for cardiovascular diseases. Despite efforts, many patients struggle to achieve target lipid levels, necessitating improved treatment strategies. Both type 1.and type 2 diabetes mellitus affect millions of adults in china,with long-term complications adding to the disease burden. Early intervention and effective management are crucial to mitigate its impact. Prevalent among older adults, chronic kidney disease is associated with diabetes mellitus, hypertension, and cardiovascular diseases, necessitating comprehensive management approaches. The prevalence of metabolic syndrome, characterized by a cluster of risk factors, has increased in both adults and adolescents, calling for lifestyle modifications and public health interventions. Ambient and household air pollution remain significant environmental risk factors, despite some improvements in air quality. Continued efforts to reduce emissions are essential for mitigating associated health risks. Addressing these risk factors requires a multifaceted approach, including public health initiatives, policy interventions, and individual-level strategies to promote healthy lifestyles and reduce environmental exposures. Surveillance and research efforts are crucial for monitoring trends and developing effective strategies to lessen the burden of cardiovascular diseases in

Mechanical Engineering and Material Science—201. International Conference on Mechanical Engineering and Material Science(MEMS 201.)

In the present work,the behavior of un-coagulable CO was experimentally investigated during the condensation process of carbothermic reduction of magnesia at condensing zone temperatures ranging from 923 K to 1.23 *** powders and magnesium lump condensates were produced under different conditions and characterized by scanning electron microscopy and energy-dispersive X-ray *** reverse reaction products C and MgO were formed following the process of magnesium vapor condensation and we just found the nearer the temperature of the condensation zone approached the liquid transition temperature,the lower the rate of the reverse reaction between CO and magnesium ***,decreases in the rate of the reverse reaction of magnesium were possible by controlling the condensation temperature in experiments.

This article proposes a degradation method of CMC in waste drilling fluid by microwave and coagulation synergetic degradation. This study investigated the influence of the coagulant dosage, pH value and reaction time and so on to the response. The result shows that the degradation effect is remarkable: the dosing quantity of ferric chloride coagulant is 80mg/L, pH = 5, microwave reaction time is 6min, the power is 700W, in this situation CMC solution could be degraded completely, This degeneration efficiency of the method is high, the time is short, the expense is low and the experiment operation is easy and feasible.
