Description

Application of hydrogen storage oyster calcium in special medical food, health care product and medicine for preventing and treating type I diabetes
Technical Field
The invention relates to the technical field of biology and medicine, in particular to application of calcium oyster hydrogen storage in foods, health products and medicines with special medical purposes for preventing and treating type I diabetes.
Background
Type i diabetes (Type I Diabetes Mellitus, T1 DM) is a chronic autoimmune disease characterized by insulin deficiency and resultant hyperglycemia. The disease is often due to autoimmune destruction, resulting in hyperglycemia and ketosis, and symptoms also include diuresis, frequent thirst, and weight loss. The rapid increase in research into type i diabetes has led to a wide understanding of many aspects of the disease over the past 25 years, including its genetics, epidemiology, immune and beta cell phenotypes, and disease burden. Currently, there are insulin or insulin analogue management and non-insulin drug therapies clinically, including metformin, glucagon-like peptide 1 receptor agonists, dipeptidyl peptidase 4 inhibitors and sodium-glucose co-transporter-2 (sglt 2) inhibitors to lower blood sugar, and in addition, islet function can be improved by pancreas or islet transplantation, gene therapy and stem cell therapy to improve islet beta cell function, ultimately achieving treatment and improvement of T1DM, but there is still a great gap for standardized clinical care of T1DM and reduction of the burden of disease-related complications. Although clinical treatment results in significant improvement in patient survival and health, healing of T1DM remains a significant challenge. Furthermore, despite technological advances, glycemic control is not optimized in most T1DM patients, making patients unsuited to modern therapies due to the high cost of basic care. Thus, there is a need for an economical and effective therapeutic regimen for alleviating and treating T1 DM.
The prior treatment technology has the defects that: insulin therapy requires daily injection therapy, consumes a great deal of money, cannot radically cure T1DM, and brings great challenges to life and economy of people. The non-insulin drug treatment can only partially relieve and not completely cure the T1DM, and the T1DM patient can also generate corresponding complications, so that the drug treatment is difficult to relieve and completely cure the development of the complications. The gene therapy, islet transplantation and stem cell transplantation therapy are huge in cost and cannot be applied to all T1DM patients, and the price of the medicine is high and cannot be borne by ordinary families, so that the need for an economical and practical treatment scheme capable of relieving the complications caused by T1DM and T1DM is urgent. Researchers have proposed novel treatment schemes, hydrogen treats T1DM, but hydrogen is unstable in water and cannot be stored for a long time, hydrogen-rich water adopts high pressure to inject hydrogen into water, once hydrogen in the pressure-free water can be quickly dissipated, the hydrogen cannot act in a living body for a long time, and the hydrogen cannot effectively act in the living body for a long time. The oyster calcium hydrogen storage is used as a solid hydrogen carrier, can react with water to continuously and efficiently release hydrogen, has sustainability and can maintain high-concentration hydrogen release for a long time, and the oyster calcium hydrogen storage can be used for treating type I diabetes.

The concentrations of hydrogen released from the hydrogen-storing oyster calcium were measured for 1h,4h,8h,24h,48h,72h,96h,120h,144h,168h,192h, respectively, while the pH of the solutions was measured, and the measurement results were shown in FIG. 1, and in FIG. 1 (A), we found that the concentrations of hydrogen in the aqueous hydrogen-storing oyster calcium solutions of 30mg/ml,100mg/ml,300mg/ml increased and then decreased with time, and that the concentrations of hydrogen in the aqueous hydrogen-storing oyster calcium solutions of 30mg/ml,100mg/ml,300mg/ml reached peak at 8h (peak concentrations of hydrogen were 520ppb,600ppb,740ppb, respectively), the concentration of the released hydrogen is increased along with the increase of the concentration of the hydrogen-storing oyster calcium, the concentration of the hydrogen released by the 300mg/ml hydrogen-storing oyster calcium aqueous solution is obviously higher than 30mg/ml and 100mg/ml, the hydrogen release gradually decreases along with the extension of time, the hydrogen release of the 30mg/ml hydrogen-storing oyster calcium aqueous solution is 0 after 96 hours, the hydrogen release of the 100mg/ml hydrogen-storing oyster calcium aqueous solution is 0 after 120 hours, and the hydrogen release of the 300mg/ml hydrogen-storing oyster calcium aqueous solution is 0 after 192 hours; as shown in FIG. 1 (B), the pH detection results show that the aqueous solution of hydrogen storage oyster calcium is alkaline (pH > 8), the pH of the aqueous solution of hydrogen storage oyster calcium is obviously increased along with the increase of the concentration, the pH of the aqueous solution of hydrogen storage oyster calcium with high dosage of 300mg/ml is higher than 13 and can be maintained for 96 hours, then the aqueous solution of hydrogen storage oyster calcium with high dosage starts to be reduced, the pH of the aqueous solution of hydrogen storage oyster calcium with high dosage of 100mg/ml is higher than 12 and is maintained for 24 hours, then the aqueous solution of hydrogen storage oyster calcium with high dosage starts to be gradually reduced, and the pH of the aqueous solution of hydrogen storage oyster calcium with high dosage of 30mg/ml is higher than 12 and is maintained for 8 hours.
(II) HOP treatment reduced fasting blood glucose and blood lipid and restored serum insulin levels in STZ-induced T1DM mice.
To investigate the therapeutic effect of HOP treatment on STZ-induced T1DM, we first induced T1DM with STZ, found that type i diabetic mice had random blood glucose greater than 16.7mmol/L after two weeks of STZ induction (fig. 2A), and that mice appeared to be polyphagic, diuretic, indicating that the STZ-induced T1DM model was successful. We then began administration of 30mg/mL HOP (L-HOP), 300mg/mL HOP (H-HOP) treatment to diabetic mice, and the C57 control and STZ model groups were administered with equal volumes of physiological saline, and H-HOP treatment was found to reduce fasting blood glucose in T1DM mice during the second week of administration (FIG. 2B), and L-HOP, H-HOP treatment was found to significantly reduce fasting blood glucose in T1DM mice for 12 hours during both the fifth and sixth weeks of administration (FIG. 2C). Furthermore, we found that administration of H-HOP treatment at week five could reduce the levels of Triglyceride (TG) and cholesterol (TC) in serum of T1DM mice starved for 12H (fig. 2D), and that both L-HOP and H-HOP treatments could significantly reduce the levels of TG and Free Fatty Acid (FFA) in serum of T1DM mice at week six of administration (fig. 2D). More importantly, in STZ-induced T1DM mice, reduced levels of insulin were found in the serum, and administration of H-HOP treatment significantly restored the levels of insulin in the serum (FIG. 2E). Overall, L-HOP and H-HOP can significantly improve the fasting blood glucose and blood lipid levels in STZ-induced T1DM mice.
And (III) the HOP treatment recovers liver, perirenal fat and epididymal fat and weight proportion of STZ induced T1DM mice, and improves liver function.
To investigate the effect of HOP treatment on STZ-induced T1DM body weight, food intake, water intake and metabolic tissue weight, we measured the body weight, food intake and water intake of mice every two days. Our study found that STZ-induced type i diabetic mice found a significant decrease in body weight on day 17, a significant increase in water intake on day 19, and a significant increase in food intake on day 27, but treatment with L-HOP and H-HOP did not significantly improve body weight, water intake, and food intake (fig. 3A-3C). Interestingly, we found that STZ-induced T1DM mice had significantly elevated liver to body weight specific gravity compared to control (C57), whereas administration of L-HOP and H-HOP treatments significantly reduced liver to body weight specific gravity of STZ-induced T1DM mice (fig. 3D); compared to the control group (C57), STZ induced a significant decrease in the specific gravity of perirenal fat and epididymal fat to body weight in T1DM mice, whereas administration of L-HOP and H-HOP treatments significantly restored these metrics (fig. 3E and 3F); in addition, L-HOP and H-HOP treatment restored STZ-induced levels of ALT/AST in liver tissue of T1DM mice (FIG. 3G). These data indicate that HOP treatment restores STZ-induced T1DM mice liver, perirenal fat and epididymal fat to body weight specific gravity, improves liver ALT/AST levels, and restores liver function.
(IV) HOP treatment reduces STZ-induced active oxygen levels and oxidative stress in key metabolic tissues of T1DM mice.
To explore the effect of HOP treatment on oxidative stress in key metabolic tissues of STZ-induced T1DM mice, we analyzed the levels of reactive oxygen species in liver, brain, heart and muscle tissues. STZ-induced T1DM mice had significantly elevated levels of ROS in liver, brain, heart and muscle tissue (FIGS. 4A-4D), and treatment with HOP reduced ROS levels in liver, brain, heart and muscle tissue (FIGS. 4A-4D) compared to control mice.
More importantly, HOP treatment can enhance liver tissue NQO1 levels and muscle tissue NRF2, NQO1, catase and SOD1 protein expression levels (fig. 3E-F).
(V) HOP treatment promotes STZ-induced fatty acid beta oxidation in brown adipose tissue of T1DM mice and inhibits lipid synthesis in liver and muscle tissues.
To explore the effect of HOP treatment on lipid metabolism in STZ-induced T1DM mice key metabolic tissues, we analyzed the level of lipid metabolism in liver, muscle and brown adipose tissue (brown adipose tissue, BAT). HOP treatment promoted STZ-induced expression of T1DM mice brown adipose tissue fatty acid beta oxidation-related gene CPT1A (fig. 5A), and inhibited expression of P-ACC, ACC and FAS lipid synthesis genes in liver and muscle tissues (fig. 5B and 5C) compared to control mice. In addition, HOP treatment promoted the expression of UCP1 protein in liver tissue, promoting thermogenesis (fig. 5B).
Sixth, HOP treatment improves the index of renal inflammation and renal function in STZ-induced type i diabetic mice.
To explore the effect of HOP treatment on the kidney function of STZ-induced type i diabetic mice, we evaluated glomerular filtration using quantitative polymerase chain reaction to detect the expression level of inflammatory factors in kidney tissue and creatinine levels in serum. Tumor necrosis factor α (tumor necrosis factor α, tnfα) in kidney tissue of STZ-induced type i diabetic mice, interleukin-1 β (interleukin 1beta, il1β), interleukin 6 (interleukin 6, il6), interleukin 10 (interleukin 10, il10) and chemokine ligand 2 (chemokine) ligand 2, MCP 1) were significantly elevated compared to control mice, and administration of L-HOP and H-HOP treatments significantly reduced the mRNA levels of il1β, IL6, IL10 inflammatory factors in kidney tissue of type i diabetic mice, L-HOP and H-HOP treatments reduced the mRNA levels of tnfα, and H-HOP could reduce the mRNA levels of MCP1 (fig. 6A). Meanwhile, to evaluate the glomerular filtration function, we examined the levels of creatinine (Scr) in Serum, and found that STZ-induced type i diabetic mice had significantly elevated levels of Scr in Serum compared to the normal control group, and administration of H-HOP treatment reduced significantly lower levels of Scr (fig. 6B). The results show that HOP treatment can reduce the transcription level of inflammatory factors and serum creatinine level in kidney tissues and can significantly improve kidney functions.
(seventh) HOP treatment reduced serum inflammatory factor levels in STZ-induced type I diabetic mice.
To explore the effect of HOP treatment on STZ-induced inflammatory levels in type i diabetic mice, we examined the serum for the inflammatory factor tumor necrosis factor α (tumor necrosis factor α, tnfα), interleukin-1 β (interleukin 1beta, IL1 β), and interleukin 6 (interleukin 6, IL 6) levels in STZ-induced type i diabetic mice serum significantly increased compared to control mice, and administration of H-HOP treatment significantly reduced the levels of tnfα inflammatory factor in type i diabetic mice serum, and L-HOP treatment significantly reduced IL6 levels in type i diabetic mice serum (fig. 7). The above results indicate that HOP treatment can significantly reduce inflammatory factor levels in serum.
