In recent years, people’s living standards are getting higher and higher, and life pressure is also increasing, and there are also many problems in eating habits. This is also the direct cause of colon cancer. The aim of this paper was to investigate whether anesthetic drugs could positively affect the proliferation and apoptosis of colon cancer cells. In this paper, the significance of anesthetic drugs is proposed, and an artificial neural network algorithm based on artificial intelligence is proposed. It is well known that artificial neural networks play an important role in medicine. The experimental results of this paper show that the incidence of colon cancer in 2020 will be in the range of 5%-35%, and the incidence of colon cancer in 2021 will be in the range of 7%-30%. While colon cancer rates in 2021 do not appear to be as high as colon cancer rates in 2020, they are generally much higher than colon cancer rates in 2020. It can be seen that as the population ages, the number of colon cancer patients is increasing due to the lack of emphasis on health. This also means that the incidence of colon cancer is getting higher and higher, and traditional drug chemotherapy has been unable to play a good role in inhibiting the proliferation of colon cancer cells. Therefore, this paper investigated the effects of anesthetic drugs on the proliferation and apoptosis of human colon cancer cells.

Recently, carbon nanomaterials doped with nonmetallic atoms have been used as electrocatalysts involved in oxygen reduction reactions (ORRs) because of the lack of degradation and contamination problems caused by metal dissolution, low cost, sustainability, and multifunctionality. In this study, the metal-free N-, P-, O-tridoped carbon hollow nanospheres (N, P, O-Carbon) with openings in the shell surfaces have been developed, where poly(o-phenylenediamine) hollow nanospheres with openings in the shell surfaces were chosen as a nitrogen-rich polymer, and then different phosphorus sources (such as NaH2PO2, H3PO4, and phytic acid (PA)) were introduced for heat treatment. When used as electrocatalysts, N, P, O-Carbon-PA showed the best ORR electroactivity with an onset potential (E onset ) of 0.98 V and the limit current density of 5.39 mA cm–2. The origin of high activity associated with heteroatom doping was elucidated by X-ray photoelectron spectroscopy and density functional theory. The results evidenced the high potential of N, P, O-Carbon as highly active nonmetal ORR electrocatalysts. It can be expected that the conclusions rendered herein will provide guidance for the reasonable design of other heteroatom-doped carbon for wider applications.

The practical application of lithium–sulfur batteries (LSBs) is partially impeded by large volume variation, severe shuttle effect, and inferior electrical conductivity of sulfur. On this account, a template-free arc-discharge method for the synthesis of TiS x (1.5 < x < 2)@HCN (hollow carbon nanocage) as an efficient sulfur host is developed for LSBs. TiS x @HCN can accommodate the volume changes of active materials and inhibit the shuttle effect of lithium polysulfides (LiPSs). Theoretical calculation shows that the defective titanium sulfide accelerates the conversion of long-chain LiPSs to intermediate species and promotes the redox reactions. As a consequence, the resulting hybrid cathode composited with sulfur exhibits excellent electrochemical performances. A reversible capacity of 1118.6 mA h g–1 is obtained under 0.1 C with a slow capacity decay of 0.108% per cycle for 200 cycles. The synthetic strategy provides a facile platform for the synthesis of nanocomposite materials.
