Spleen is the acquired essence. Normal transport function of spleen is the premise of Qi and blood biochemistry. Is also a necessary condition for fine substances to be transported throughout the body. Mitochondria are the main sites of energy metabolism and the function of spleen to generate Qi and blood to promote various kinds of body movements. It is similar to the function of mitochondria to provide energy for body activities. Mitophagy maintains cell homeostasis mainly through clearing damaged mitochondria and its expression is closely related to the activity of DRP1. As the source of Qi and blood biochemistry, the spleen is extremely important for maintaining the power required by the body. Related studies have found that strengthening the spleen increases the expression of Parkin and promotes mitophagy. Osteoporosis is one of the common complications of diabetes. Its onset is closely related to the decrease of muscle content caused by insulin resistance and microangiopathy, atherosclerosis caused by disorder of lipid metabolism and mitochondria degenerate due to oxidative stress induced by excessive production of oxidative free radicals in high glucose environment. Mitophagy eliminates the damaged mitochondria and reduces the damage to the mitochondria with sound structure and function to reduce the degree of insulin resistance and the risk of microangiopathy and atherosclerosis to prevent and treat diabetic osteoporosis. Therefore, based on the spleen mitochondria theory, this paper discusses the relationship between mitophagy and diabetic osteoporosis. [ABSTRACT FROM AUTHOR]

Abstrac: Bone is the master of kidney, the essence resides in the kidney, essence can produce pulp, kidney essence deficiency will lead to the reduction of bone marrow metaplasia, bone loss pulp nourishing, over time is the development of bone wilt. Mitochondria are the "power factories" of life activities. The proliferation, differentiation and apoptosis of human cells depend on the normal function and the normal expression of related signaling pathways of mitochondria. Traditional Chinese medicine believes that Yuan Qi resides in the kidney, depending on sufficient kidney essence, and its functions of leading human growth and development, stimulating metabolism and other life activities are similar to those of mitochondria regulating cell life activities in modern medicine. Kidney, as one of the important organs of body fluid metabolism, is mainly involved in body fluid transport and excretion through gasification function. Its dysfunction will also lead to body fluid transport, thereby obstructing accumulation of sputum. With the recent in-depth research on the relationship between kidney and body fluid, the theory of "kidney phlegm" has gradually gained popular support. "Most diseases are caused by phlegm", with the progress of aging, kidney essence gradually deficient, kidney qi deficiency, will lead to body fluid metabolism disorder and produce "kidney sputum", and then lead to the occurrence of various diseases. Oxidative stress reaction is a risk factor for a variety of diseases. As an important factor affecting the occurrence of oxidative stress reaction, the accumulation of oxidative free radicals is related to the aging of the body. Relevant studies have shown that excessive apoptosis of osteoblasts caused by oxidative stress will lead to increased risk of osteoporosis. The main mechanism is related to the damage of mitochondrial function and the abnormal expression of Wnt/B-catenin and other related signaling pathways. Therefore, sputum and oxidative free radicals have a lot in common in both the generation and pathogenic characteristics. Therefore, this paper discusses the relationship between mitochondrial oxidative stress and osteoporosis based on the theory of "kidney is the root of phlegm". [ABSTRACT FROM AUTHOR]

Objective The aim is to solve the problem that the natural gas hydrate formed in the process of gathering and production of natural gas blocks the pipeline, wellbore and porous media in the formation. Methods A kinetic hydrate inhibitor NADN was synthesized with N-vinyl pyrrolidone (NVP), allyl polyethylene glycol (APEG-1000), dimethyl diallyl ammonium chloride (DMDAAC) and N-hydroxymethyl acrylamide (N-HAM). The optimum synthesis conditions were obtained by single factor experiment. Results The molar ratio of n (NVP), n (DMDAAC), n (N-HAM), n (APEG-1000) was 1∶2∶2∶0.3, reaction temperature was 60 ℃, reaction time was 6 h, and monomer concentration was 35%, the mass of initiator accounts for 0.3% of the total mass of monomer. The structure was consistent with the original design structure by FIRT and ¹H NMR. Conclusions Experiment results showed that when the dosage of inhibitor reaches 1.05%, it showed excellent inhibition effect under the ambient temperature of-18 ℃. The freezing temperature of hydrate could be as low as-7.5 ℃. [ABSTRACT FROM AUTHOR]

A medium entropy alloy (Fe63.3Mn14Si9.1Cr9.8C3.8)100-xYx(Y=Ag, Cu) was fabricated via a water cooled copper crucible magnetic levitation melting and copper mold negative pressure suction casting method. The effects of adding Ag and Cu elements micro alloying on the stacking fault energy, microstructure, mechanical properties and magnetic properties of the alloy were studied by XRD, SEM and VSM. The results show that the alloy contains fee phase and low stacking fault energy. The addition of diamagnetic elements Ag and Cu further reduces stacking fault and refines grain size, decreases the yield strength and improves the fracture strength and plasticity. The fracture strength and plasticity of(Fe63.3Mn14Si9.1Cr9.8C3.8)99.6Cu0.4 alloy are up to (2 435 ± 1) MPa and (22.2±0.1)%, respectively, while the relative permeability is just 1.00013, thus indicating excellent mechanical properties and paramagnetism.
