Research progress on traditional Chinese medicine compounds combined with external therapy in treatment of hyperplasia of mammary glands / 中国中药杂志

Hyperplasia of mammary glands is a benign breast disease with disordered breast structure. Nowadays, the incidence rate of breast hyperplasia in women is increasing year by year, and the etiology is related to the imbalance of estrogen and progesterone in the body. The symptoms include breast pain, breast nodules, or nipple discharge, which can develop into breast cancer in the context of psychological pressure. Therefore, it is timely and effectively necessary for people to treat the symptoms. At present, traditional Chinese medicine(TCM) often treats breast hyperplasia by oral drug, external application, acupuncture, moxibustion, and massage, while western medicine often uses hormone therapy or surgery. TCM can regulate hormone levels to treat breast hyperplasia. Acupuncture, moxibustion, and other methods can stimulate acupoints to reduce breast lumps. However, since TCM is easy to produce hepatorenal toxicity after long-term use and simple external treatment is slow to take effect, rapid and effective treatment is difficult to be achieved. Although western medicine can inhibit the disease, it is easy to produce toxic and side effects if taken for a long time. In addition, surgery can only remove the focus and the recurrence rate is high. Some studies have found that the combination of oral and external use of TCM compounds has a significant effect, with mild toxic and side effects, few adverse reactions, and a low recurrence rate. Based on the relevant literature in recent years, this article reviewed the combination of oral and external treatment of TCM in the treatment of hyperplasia of mammary glands, discussed the effectiveness, clinical evaluation indexes, and mechanism, and pointed out the existing shortcomings to explore a comprehensive therapy worthy of clinical application.

Optimization of Prescription of Lycii Fructus Polysaccharide Buccal Tablets by Central Composite Design-response Surface Methodology and Investigation of Its Immunomodulatory Effect / 中国实验方剂学杂志

Objective:To prepare Lycii Fructus polysaccharide buccal tablets and investigate its immunomodulatory effect. Method:Taking the appearance, taste, hardness and disintegration time of the tablets as comprehensive evaluation index, based on single factor tests, central composite design-response surface methodology was adopted to optimize the prescription of Lycii Fructus polysaccharide buccal tablets with mass ratio of dextrin to mannitol, mass ratio of cyclamate to malic acid and dosage of sodium carboxymethyl starch (CMS-Na) as factors. Kunming mice were randomly divided into 5 groups, namely the Lycii Fructus polysaccharide buccal tablets low (100 mg·kg-1·d-1), medium (200 mg·kg-1·d-1) and high (300 mg·kg-1·d-1) dose groups, the normal group (0.9% normal saline, 300 mg·kg-1·d-1) and the positive medicine group (Cinengsu group, 300 mg·kg-1·d-1). The immunomodulatory effect of the buccal tablets were investigated by calculating immune organ index, monocyte-macrophage phagocytic index, serum hemolysin antibody level, and the voix pedis thickness difference of delayed hypersensitivity (DTH) of mice. Result:Optimal prescription for the buccal tablets was 80% of Lycii Fructus extract, 11.5% of dextrin-mannitol (1.2:1), 1% of cyclamate-malic acid (1:1), 0.5% of cream essence, 6.5% of CMS-Na, 0.5% of magnesium stearate, and appropriate amount of 80% ethanol. Under the optimal condition, the hardness of the buccal tablets was 11.83 kg, its disintegration time was 13.21 min, both of which were in line with the relevant provisions of the 2015 edition of Chinese Pharmacopoeia, and the buccal tablets had good appearance and taste. Compared with the normal group, medium and high dose groups of Lycii Fructus polysaccharide buccal tablets significantly increased thymus index, spleen index and phagocytic index of mice (PPPPPConclusion:The formulation process of the buccal tablets optimized by central composite design-response surface methodology is stable and feasible, and Lycii Fructus polysaccharide buccal tablets can improve the immune regulation function of normal mice, and this study can provide experimental basis for the development, utilization and clinical application of Lycii Fructus and Lycii Fructus polysaccharides.

HPTLC Fingerprints of Total Saponins of Aralia elata Leaves / 中国实验方剂学杂志

Objective: To establish high performance thin layer chromatography (HPTLC) fingerprint of the total saponins from Aralia elata leaves, and compare the difference of components in A. elata leaves from different harvest time and different regions.Method: High efficiency silica gel G thin sheet (20 cm×20 cm) was used,with chloroform-methanol-ethyl acetate-water (9.5:10:20:0.5:5) as developing system,ethanol solution of 10% concentrated sulfuric acid as chromogenic reagent,heating at 100℃ in constant-temperature air dry oven until clear spots. The fluorescence HPTLC chromatogram fingerprints were obtained under 365 nm ultraviolet light. Speckle patterns were obtained by software processing and the common pattern was established for similarity analysis and cluster analysis.Result: The HPTLC fingerprints with good separation and clear spots were obtained and the common pattern of fingerprints was established. The common pattern was composed of 10 common speckled peaks,4 of which were identified for components. The results showed that samples in early August to mid September from different regions had good similarity. 11 samples of different batches were clustered into one class.Conclusion: The HPTLC method is simple, fast and reliable, and can be used for the identification and quality evaluation of medicinal materials of A. elata leaves. The A. elata leaves collected in August conform to the quality standard, so they can be used as medicinal materials.
