Abstract

Objective: To analyse the curative effect of traditional Chinese medicine combined with metformin hydrochloride on diabetes and its effect on TNF-α, MCP-1 and NO.

Methods: 80 cases of diabetics who were treated at XX hospital from January of 2014 to January of 2015 were chosen as research subjects, according to random indicator method divided into control group and experimental group with 40 cases in each group. The patients in the control group were treated with metformin hydrochloride alone, and the patients in the experimental group received Chinese medicine combined with metformin hydrochloride. To compare the TCM syndrome points, Fasting Blood Glucose (FBG) and 2 h postprandial blood glucose (2 h PG), Fasting Insulin (FINS) and 2 h postprandial insulin (2 h INS) levels of two groups of patients before and after the implementation of treatment, at the same time observing he levels of TNF-α, MCP-1 and NO before and after treatment.

Results: After treatment, the TCM syndromes in the experimental group were significantly better than those in the control group (P<0.05), and FBG, 2 h PG, FINS, 2 h INS were significantly lower than those in the control group (P<0.05), as same as the levels of TNF-α, MCP-1 and NO.

Conclusion: Chinese Medicine combined with metformin hydrochloride tablets can effectively treat diabetes and reduce the concentration of TNF-α, MCP-1 and NO in the blood.

Introduction

Diabetes is a metabolic disease characterized by high blood sugar. Hyperglycemia is caused by insulin-secretion or biological damage, or both. Diabetes and high blood sugar can lead to chronic damage and dysfunction of some tissues, especially the eyes, kidneys, heart, blood vessels, and nerves. At present the main treatment method of diabetes oral glucoselowering drugs which can reduce blood sugar. Metformin is the most commonly used first-line drugs, mainly by reducing liver glycoxis [1], the inhibition of intestinal mucosa cells to absorb glucose give play to the role of hypoglycemic, which has definite curative effect on treatment of diabetes [2]. For the treatment of diabetes, hypoglycemic drug treatment effect is not ideal, and long-term use of the effect will be reduced [3], so there is still lack of effective treatments [4]. In this study, a combination of metformin hydrochloride and metformin hydrochloride was used to investigate the effect of metformin in the treatment of diabetes mellitus and the influence of TNF- α, McP-1 and NO concentration in the blood.

Materials and Methods

General information

Ethical approval was given by the medical ethics committee of Sixth People's Hospital of Qingdao with the following reference number: 2015006, 80 patients with diabetes in XX hospital between January 2014 and January 2014 were selected as the research object, In accordance with the table method randomly divided all the research object into two groups, control group and experimental group, respectively, 40 cases in each group. In the control group, the treatment of metformin hydrochloride was made in the experimental group. There were 21 males and 19 females in the control group, aged 35 to 62 y, with an average of (43.35 ± 5.12 y). In the observation group, 23 cases of males and 17 cases of female, age 38 to 69 y old, the average (55.16 ± 5.36 y) of age. By comparison, there was no statistically significant difference between the two groups in terms of gender, age, and other general data (P˃0.05).

Standard of diagnosis

Diagnosis standard reference pacing “internal medicine” [5] (7th edition) in the relevant diagnostic criteria for type 2 diabetes: Fasting Blood Glucose (FBG) ≥ 7.0 mmol/L, or patients with postprandial blood glucose 2 h (2 h PBG) ≥ 11.1 mmol/L.

Conclusion

Diabetes has a higher incidence in our country especially among obese people. Traditional treatments rely on glucoselowering drugs such as metformin hydrochloride to control blood sugar levels and weight loss. But simply by increasing the dosage of metformin hydrochloride to control the rise in blood sugar, it is easy to cause the drug resistance of the body and affect the therapeutic effect. And it is not ideal to rely solely on western medicine. Diabetes in patients with type 2 diabetes in the normal insulin secretion and self-adjustment disorder, and the ability to influence of lipid and protein metabolism, prone to metabolic disorders, and increased risk of diabetes complicated with lipid and protein metabolism lesions [6].

Diabetes is a kind of “quenching thirst” in TCM syndrome differentiation, which is considered to be the pathological basis of diabetes. The function of spleen and renal is transport water and essence of water and grain, so the spleen kidney deficiency, the unfavorable transportation is the disease machine key of diabetes [7-10]. The transformation of the spleen is dependent on the driving effect of qi, and the spleen deficiency cannot be transported, resulting in the blood glucose rising in the blood. The physiological function of the spleen in traditional medicine actually covers the physiological function of the pancreas, while the changes of pancreas belong to the pathological changes of the spleen, essentially is the pathogenesis of collateral of pixu (spleen deficient). Antibacterial anti-inflammatory in this prescription, bacteria resistance and bacteriostasis of Fructus cnidii, restrain the blood of lotus seeds, antibacterial anti-inflammatory and fall blood sugar of dogwood, bacteria resistance and bacteriostasis of cortex dictamni, fructus alpiniae oxyphyllae into the spleen meridian and warming spleen and dispel cold, mulberry into renal meridian and reinforcing kidney to replenish kidney essence, Chinese yam can tonifying spleen nourishing the stomach and generating saliva to benefit lung. Radix Astragali preparata can tonify qi and strengthen the exterior. Clearing damp and promoting diuresis of Poria locos. Gallnut of reinforcing the kidney and controlling nocturnal emission, antisepsis and anti-inflammation. Invigorating spleen and stomach of chicken's gizzard-membrane. Sanqi regulates blood sugar. Therefore, this study makes a significant therapeutic effect on the spleen, invigorating the spleen, invigorating the spleen, the biochemical fluid, and regulating the endocrine.

This experiment adopted TCM plus metformin hydrochloride in 40 patients with diabetes treatment, the results showed that after 12 w of treatment, patients with traditional Chinese medicine combined therapy with metformin enteric-coated metformin hydrochloride in FBG, 2 h PG, FINS and 2 h INS improvement is superior to pure metformin hydrochloride treatment group, shows that Chinese and western medicine can effectively reduce the patients of FBG, 2 h PG and FINS and 2 h INS, indicates that Chinese and Western medicine combination can effectively control diabetes plays a positive role to prevent or improve diabetes complications [11].

Diabetes caused by vascular disease is a major cause of damage, while inflammatory factors throughout the whole process of the onset of vascular inflammation [12-15]. The studies have shown that people with diabetes in their blood, the concentration of the inflammatory factors significantly increased [16-18], and TNF-α of the Zang-Fu organs has strong toxicity, skin cell activation, it can induce organ leucocyte migration, granulocyte degranulation and blood capillary leakage, etc., thus inducing and further aggravate the inflammatory response. McP-1 is a bisectional molecule that is specific to mononuclear macrophages, which participates in the occurrence of inflammation. NO is a dual cell messenger molecule and cytotoxic molecule. Therefore, inflammatory factor TNF-α, chemokine McP-1 and inflammatory media NO can accurately reflect the infection of the microinflammation of the body, which is an indicator of the inflammation of the body and the development of the disease. This study found that patients with traditional Chinese medicine combined therapy with metformin enteric-coated metformin hydrochloride the TNF-α, MCP-1, NO level significantly lower than the control group patients, showed that Chinese and western medicine combination can effectively control inflammation, diabetes and can improve the inflammatory state of diabetic patients.

So, the use of traditional Chinese medicine prescription with metformin hydrochloride therapy of diabetes can be offset by increasing dosage to improve the effect of western medicine, and improve the body immunity, strengthen the spleen and kidney, tonic Yin losses, providing a possibility for diabetes fundamentally.
