Description

Novel traditional Chinese medicine compound for preventing and treating sicca syndrome as well as preparation method and application thereof

Technical Field

The invention relates to a medical application of a traditional Chinese medicine compound for preventing and treating sicca syndrome, in particular to an application of the compound in treating the sicca syndrome.

Background

Sicca syndrome (A)

SS) is also known as sjogren's syndrome and is a chronic inflammatory autoimmune disease that involves primarily the exocrine glands. It is divided into primary and secondary categories. The typical clinical manifestations are that salivary gland and lacrimal gland are damaged, the function is reduced, and the symptoms of dry mouth and eyes are caused, and other exocrine glands and other organs outside gland body are involved to cause multi-system damage. There are a number of autoantibodies and hyperimmune globulin in the patient's serum. Sjogren syndrome occurs well after menopause or in women between 30 and 40 years of age, with a prevalence of about 0.3-0.4% and up to 0.77% in the elderly population.

No radical cure method is available for the disease at present. In clinic, measures are mainly taken for improving symptoms, controlling and delaying the progress of tissue and organ damage caused by immune response and secondary infection. The treatment aims to relieve dry mouth and dry eyes. The western medicine clinical treatment mainly comprises substitution therapy and symptomatic treatment, wherein the substitution therapy adopts 'artificial tears', 'saliva substitute' and the like as local treatment medicines for improving dry eyes and dry mouths. And symptomatic treatment such as systemic treatment with hydroxychloroquine sulfate, glucocorticoid, and immunosuppressant (such as cyclophosphamide). The use of biologics such as B lymphocyte monoclonal antibodies (e.g., CD20 and CD22 monoclonal antibodies) to increase residual salivary gland function stabilizes Ig G levels. Other approaches such as muscarinic agonists, stem cell therapies, etc. have also been investigated. But all are difficult to cure radically and easy to repeat.

Under the guidance of the holistic view and syndrome differentiation theory of traditional Chinese medicine, the traditional Chinese medicine has certain effect on preventing and treating sicca syndrome. Total glucosides of paeony is a classic and effective Chinese patent medicine for treating sicca syndrome at present, is an immunomodulator, and can adjust over-high or over-low immunity of a patient to a normal level. But when used alone, the traditional Chinese medicine composition has slow effect, can not quickly improve the dry mouth and eyes symptom, and can not quickly reduce the infiltration degree of gland lymphocytes and reduce the expression quantity of autoantibodies. In patent 201210296796.0, although the compound of Chinese herbal medicine using white peony root as one of the main Chinese herbal medicines has been shown to effectively inhibit rheumatoid factor and antibody index, it has not good intervention effect on lymphocyte infiltration, autoantibody SSA, SSB, ANA, inflammation TNF- α, BAFFR factor, etc. in gland with xerosis specificity. In addition, some Chinese herbal compound medicines are applied to the treatment of the sjogren syndrome, such as patents 201210345391.1 and 201610918771.8, but the Chinese herbal compound medicines have the defects of more traditional Chinese medicines, more complex formula and preparation process, more dosage of single-day medicine and the like.

Example 5

1. Experimental research on effect of traditional Chinese medicine compound extract on relieving dry eye

The specific implementation scheme is as follows: SPF grade Balb/C mice, 48, female, weighing 18-22 g. The mice were randomly divided into 5 groups (n ═ 8) except the normal group, and the sicca syndrome mouse model was replicated using the scopolamine hydrochloride method, with a model replication cycle of 10 days. The mice were divided into a normal control group, a negative control group, a positive drug group (total glucosides of paeony tablets, 0.182g/kg calculated by clinical dose), and groups of examples 1-3 in sequence. Treatment is given from d11, wherein the normal group and the negative control group are perfused with gastric saline, the positive drug group is perfused with gastric white peony root total glycoside liquid medicine, and the test liquid medicine with corresponding concentration is perfused in the groups of examples 1-3. The gavage volume is 1mL/20g body weight, 1 time per day, and the gavage is continuously carried out for 15 days. During this period, tears were removed from the slide glass every 5 days and examined microscopically (200X) for tears crystallization. The weight change and water intake of the mice were measured every 2 days. The test results are shown in table 1, table 2 and fig. 1.

TABLE 1 weight gain in mice during dosing (g, Mean + -SD)

Note: (vi) a set of negative models,^*P<0.05or^**P<0.01; vs. total glucosides of paeony group,^#P<0.05or^##P<0.01。

the results show (Table 1) that the body weight of mice in the negative model group was significantly reduced during the administration period compared with that in the normal group (^**P<0.05); mice in the total glucosides of paeony group and the groups of examples 1-3 showed significant weight regain trend from day 3 of administration (d13) compared with the negative model group (see (1))^*P<0.05or^**P<0.01); compared with the positive control group of total glucosides of paeony, the mice in the examples 1-2 have significantly lower body weight regain than the total glucosides of paeony group (^#P<0.05or^##P<0.01); however, in example 3, there was no significant difference in the mouse body weight regain (P)>0.05), which shows that the effect of example 3 on the improvement of the body weight of the mice is equivalent to that of the positive control group.

TABLE 2 change in water intake of mice during dosing (mL, Mean + -SD)

the results show (Table 2) that the consumption of water by the mice in the negative model group was significantly increased during the administration period compared with the normal group (^*P<0.05or^**P<0.01); compared with the negative model group, the water intake of mice in the total glucosides of paeony group and the groups of examples 1-3 is remarkably reduced after d 13; compared with the total glucosides of paeony positive group, the water intake of example 1 at d13 and d15 is significantly lower than that of the total glucosides of paeony group (45.0 + -4.3 mL and 35.0 + -3.9 mL), 32.4 + -3.8 mL and 29.0 + -3.4 mL, respectively (^#P<0.05or^##P<0.01). The water intake of the mice in the examples 2 and 3 is not obviously different from that of the white paeony root total glycoside group. It is demonstrated that examples 1-3 had an effect on reducing the water intake of mice comparable to that of the total glucosides of paeony group.

The results show that fern crystal form of model mouse tear crystals is lost (form IV) in irregular punctate form due to the lack of mucin. After 15 days of administration (d25), the tear crystalline forms were improved in both the total glucosides of paeony group and the test group (both form II), except for the model group. Compared with the total glucosides of paeony positive group, the tear crystal forms of the test groups, the examples 2 and the examples 3 have no significant difference with the positive control group.

The test result shows that: the traditional Chinese medicine compound extract has the comprehensive effects of maintaining the weight of a mouse, reducing the water intake of the mouse, repairing the crystalline form of tears and relieving the dry eye disease or is superior to the total glucosides of paeony. The research result can reflect that the traditional Chinese medicine compound extract can prevent and treat dry eye diseases to a certain extent.

2. Experimental study on gland function improvement of traditional Chinese medicine compound extract

The specific implementation scheme is as follows: SPF-grade BALB/c mice 48, female, weighing 18-22 g. The mice were randomly divided into 5 groups (n ═ 8) except the normal group, and the sicca syndrome mouse model was replicated using the scopolamine hydrochloride method, with a model replication cycle of 10 days. The mice were divided into a normal control group, a negative control group, a positive drug group (total glucosides of paeony tablets, 0.182g/kg calculated by clinical dose), and groups of examples 1-3 in sequence. The treatment is started from d11, wherein the normal group and the negative control group are perfused with gastric saline, the positive control group is perfused with gastric white peony root total glycoside liquid medicine, the test liquid medicine with corresponding concentration in the groups of examples 1-3 is perfused with gastric lavage with the gastric lavage volume of 1mL/20g body weight for 1 time/day, and the continuous gavage is carried out for 15 days. After the dosing period was completed, the orbit was bled and the mice were sacrificed. Dissecting, respectively taking submaxillary gland tissue and salivary gland tissue, and placing in 4% neutral formaldehyde solution for 48 h. Then, the slices are sliced after paraffin embedding treatment, and the thickness is 5 mu m; placing the slices in an oven, drying until paraffin is melted, immediately soaking in xylene, and repeating for 2 times; soaking in gradient ethanol (anhydrous, 95%, 90%, 85%, 80%, 75%, 70%) for 10min, and placing in double distilled water; boiling in citrate buffer solution with pH of 6.0 and concentration of 0.01mol/L for 10min for antigen retrieval; washing with running water, washing with distilled water for 3min, and soaking in hematoxylin staining solution for 5 min; washing with flowing water, differentiating with 1% hydrochloric acid ethanol differentiation solution for 5s, and bluing in flowing water for 30 min; soaking in 70% ethanol and 80% ethanol for 3 min; staining with hematoxylin-eosin (HE), soaking in ethanol, and dehydrating for 3 min; and sealing the piece with xylene transparent and neutral resin. Pathological changes such as spleen and the like are observed under a microscope, 5-8 pathological sections are randomly photographed under 100-fold and 200-fold visual fields respectively, and the lymphocyte infiltration degree is evaluated by adopting a Chisholm-Mason histological scoring standard. Grading the grading standard: 0 point, occasional lymphocyte infiltration; 1, dispersing in a small amount of lymphocyte infiltration; 2-moderate infiltration of lymphocytes (not foci) with mild parenchymal lesions; and 3 points are 0-1 lymphocyte infiltration foci occasionally and 5 low-power visual fields. With moderate parenchymal lesions; 2-3 lymphoblastoid infiltrates were easily seen in 4 points, 5 low power fields with severe parenchymal injury. Onset of disease is classified into more than 2 points. The results are shown in tables 3 and 4.

TABLE 3 mouse glandular tissue lymphocyte infiltration score (Mean + -SD)

the results showed that (Table 3), the degree of lymphocyte infiltration in submaxillary gland tissue of mice in the negative model group was 3.40. + -. 0.55 (compared with that in the normal group)^**P<0.01); the degree of lymphocyte infiltration in submaxillary gland tissues was significantly reduced in the total glucosides of paeony group and the test group examples 1-3, as compared with the negative model group (^*P<0.05or^**P<0.01), 2.40 + -0.55, 2.60 + -0.55, 1.80 + -0.45 and 1.60 + -0.55 respectively; the infiltration scores of the group of example 3 were significantly reduced compared to the total glucosides of paeony group (^#P<0.05). It is demonstrated that example 3 inhibits lymphocyte infiltration in submaxillary gland tissue better than the positive control total glucosides of paeony group.

The results show (Table 3) that the degree of lymphocyte infiltration into salivary gland tissue of mice in the negative model group is higher than that in the normal group by 4.10 +/-0.55%^**P<0.01); the degree of lymphocyte infiltration in salivary gland tissues was significantly reduced in the total glucosides of paeony group and the test group examples 1 to 3, as compared with the negative model group (^**P<0.01), 2.80 + -0.57, 2.50 + -0.50, 1.80 + -0.57 and 1.40 + -0.42, respectively; examples 2-3 groups were assessed for infiltration compared to the total glucosides of paeony groupThe average is remarkably reduced (^#P<0.05or^##P<0.01). The inhibition effect of the examples 2 and 3 on the lymphocyte infiltration of the salivary gland tissue is better than that of the positive control white paeony root total glycoside group.

The test results show that: the traditional Chinese medicine compound extract has better inhibition effect on the infiltration degree of the lymph cells of submaxillary gland tissues and salivary gland tissues than the positive total glucosides of paeony. The research result reflects that the traditional Chinese medicine compound extract has the functions of protecting the integrity of glandular tissues of secretory glands and maintaining the basic functions of glandular tissues to a certain extent.

3. Test for reducing level of autoantibody by using compound traditional Chinese medicine extract

the results show (Table 6) that the peripheral serum TNF-alpha expression level of mice in the negative model group is significantly increased compared with that in the normal group (^**P<0.01); compared with a negative model group, the total glucosides of paeony can obviously reduce the expression quantity of TNF-alpha in peripheral serum of mice in the total glucosides of paeony group and tested groups of examples 1-3, the expression quantity of the TNF-alpha in the total glucosides of paeony group is 48.6327 +/-4.6231 pg/mL, and the expression quantities of the TNF-alpha in the examples 1-3 are 49.3328 +/-3.2545 pg/mL, 48.5520 +/-4.3418 pg/mL and 44.5130 +/-1.2311 pg/mL respectively. Compared with the positive control group of total glucosides of paeony, the TNF-alpha expression level in the example 3 is obviously reduced, and the statistical difference is shown in (^#P<0.05). It is shown that example 3 has an improved effect on the inhibition of TNF-alpha expression over total glucosides of paeony.

BA in peripheral serum of mice in the negative model group, as compared with the normal groupThe FFR expression quantity is obviously increased (^**P<0.01); compared with the negative model group, the test group, namely example 1 and example 3, can obviously reduce the BAFFR expression level in the peripheral serum of the mice, namely 9.3760 +/-0.4305 ng/mL and 9.3783 +/-0.3173 ng/mL respectively. However, the total glucosides of paeony positive control group and the control group of the white paeony have no obvious inhibition effect and are 9.9608 +/-1.1633 ng/mL and 9.3918 +/-0.4612 ng/mL respectively. The expression level of BAFFR in example 3 is significantly reduced compared with the positive control group of total glucosides of paeony (statistical difference) ((R))^#P<0.05). It is demonstrated that example 3 has an inhibitory effect on BAFFR expression superior to total glucosides of paeony.

TABLE 7 mouse spleen coefficient variation (Mean + -SD)

the results showed (Table 7) that spleen coefficients were significantly reduced in mice of the negative model group compared to the normal group (^*P<0.05) and is 1.3 +/-0.4. Compared with the negative model group, the spleen coefficients of the total glucosides of paeony group and the examples 1 to 3 are significantly higher than those of the model group, namely 2.2 +/-0.8, 2.1 +/-0.6, 2.5 +/-0.9 and 2.8 +/-0.8 respectively. The spleen coefficients of examples 1-3 were not statistically different compared to the total glucosides of paeony positive group. It is demonstrated that examples 1-3 have comparable maintenance of spleen coefficients in mice to total glucosides of paeony.

HE staining results showed (fig. 2) that spleen white marrow of mice in the negative model group was heavily proliferated and germinal center was protruded (grade 3) compared with the normal group (grade 0); compared with the negative model group, the white marrow hyperplasia degree of the white peony root total glycosides group is relieved (grade 2), and the spleen white marrow hyperplasia can be obviously reduced in the tested groups of examples 1-3 (grade 1). Compared with the total glucosides of paeony positive group, the tested groups of examples 1 to 3 have better effect of reducing the splenic leukoplakia hyperplasia than the total glucosides of paeony group.

And (3) test results: the traditional Chinese medicine compound extract has the effects of reducing the expression quantity of TNF-alpha and BAFFR in peripheral serum, reducing spleen myelogenous hyperplasia and improving the spleen coefficient of mice, and is obviously superior to the white paeony root total glycoside positive group. The research result reflects that the traditional Chinese medicine compound extract has good anti-inflammatory effect to a certain extent.

Example 6 examination and implementation-determination of maximum dose of Compound extract of Chinese medicinal herbs

The specific implementation scheme is as follows: SPF-grade BALb/c mice 20, female, weighing 18-22 g. The groups were randomly divided into 2 groups of 10 individuals, each group was a normal control group (normal saline) and an example 4 group (maximum concentration liquid medicine prepared by the compound extract of the Chinese herbal medicine according to example 4). Fasting was 12h (without water deprivation) before the experiment, and gavage was performed in both groups, 1mL/20g body weight, 1 time/day, and 15 days. And recording and observing death conditions, daily weight increase conditions and daily water intake of the mice, observing and recording appearance signs, behavior activities, mental states, appetite, fur, skin color, breathing, excrement and urine and color of the mice, and abnormal secretions of the oral, nasal and ocular genitals and the like, and continuously observing for 15 days. After 15 days, the patient is killed after neck removal, dissected, and visually observed for main organs such as heart, liver, spleen, lung, kidney, gastrointestinal tract and the like, and has obvious pathological morphological changes.

The test results show that the administration dosage is 55 times of the clinical dosage of the adult calculated by the adult weight of 60 kg. After the mice are perfused with the extract with the maximum concentration and the maximum volume, the mice in the group of example 4 have the appearance signs, the behavior activity, the mental state, the appetite, the urine color, the fur, the skin color and the breathing are all normal, and the genitals of the nose, the eye and the oral cavity and the like have no abnormal secretion; the color of the stool particles is dark, the hardness of the particles is moderate, and the constipation phenomenon is avoided. After dissection, the internal organs of both groups of mice were normal. The mice in example 4 and normal groups showed no significant difference in body weight and food intake (P >0.05) as detailed in Table 8, Table 9 and Table 10.

TABLE 10 mouse abnormalities, deaths, and anatomical changes

The basis for selecting total glucosides of paeony as a positive control drug is as follows:

the specific implementation scheme is as follows: SPF grade Balb/C mice 32, female, weight 18-22 g. Except for the normal group, the other mice replicated the sjogren syndrome mouse model by the scopolamine hydrochloride method, and the model replication was completed after 10 days and was randomly grouped (n ═ 8). Mice were divided into normal group, total glucosides of paeony group, hydroxychloroquine group, and example 2 group. The total glucosides of paeony liquid (converted into mouse dose of 0.182g/kg according to clinical dose) is administered to the total glucosides of paeony group except normal group mice; the hydroxychloroquine group is given with hydroxychloroquine sulfate liquid medicine (converted into mouse dose of 0.03g/kg according to clinical dose); the group of example 2 was administered with the respective test solutions. The gavage volume of the mice is 1mL/20g of body weight, 1 time per day, and the gavage is continuously carried out for 15 days. During the period, the weight change and water intake of the mice were measured every 2 days. After the experiment was completed, mouse spleen weight and spleen coefficient were measured. The test results are shown in tables 11, 12 and 13.

Through the investigation of the weight, the water intake and the spleen coefficient of the mice, the intervention effect of the two positive drugs on the SS mice is compared. The results show that the treatment effect of the total glucosides of paeony group is remarkably better than that of the hydroxychloroquine group, and the treatment effect of the group of example 2 is equivalent to that of the hydroxychloroquine group. Therefore, the total glucosides of paeony is preferably used as a positive control drug in the test.
