ABSTRACT

In this paper, by consulting the historical herbs and medical classics coupled with related literature in modern research, the historical edition of Chinese Pharmacopoeia and local chronicles of traditional Chinese medicine (TCM) along with the ancient historical evolution of the processing methods of Pinelliae Rhizoma origin as well as the related processing methods of Pinelliae Rhizoma origin from 1959 to 2020 were systematically collated and summarized. It was found that the main processing methods of Pinelliae Rhizoma origin were peeling, decoction washing, lime wrapping and sun-drying. However, stacking, peeling, sun-drying or oven-drying are the primary methods in modern local chronicles of TCM. Meanwhile, washing, peeling, removing fibrous roots and sun-drying are the main methods in Chinese Pharmacopoeia. In addition, there were some changes in the quality evaluation of Pinelliae Rhizoma in different historical periods. Round and white were the best in the quality evaluation of Pinelliae Rhizoma in ancient times, while the evaluation indexes were further refined to size, color, texture, powder property, purity and evenness in modern herbal works. In modern studies, the quality of Pinelliae Rhizoma was mostly evaluated by the chemical components such as alkaloids, total organic acids, polysaccharides, nucleosides, fingerprint and pharmacodynamics. At present, the purification and drying stages of Pinelliae Rhizoma are in the transitional stage between the traditional manual peeling and natural drying methods as well as the modern mechanized and large-scale production. Therefore, a reasonable and feasible modern processing methods and guiding standards of Pinelliae Rhizoma are developed urgently to normalize the processing of Pinelliae Rhizoma and ensure the quality of medicinal materials.

ABSTRACT

OBJECTIVE:To study the effects of stilbene glucoside (TSG)on the proliferation and estrogen receptor (ER)of human breast cancer T- 47D cells ,and to explore its estrogen-like effect and potential mechanism. METHODS :Taking ER positive human breast cancer T- 47D cells as subjects ,using β-estradiol(β-E2,1×10-8 mol/L)as positive control ,CCK-8 assay was used to detect the cell proliferation after treated with different concentrations of TSG (1×10-8,1×10-7,1×10-6,1×10-5,1×10-4 mol/L)for 24,48,72 h;the cell proliferation rate was calculated. Western blotting assay and RT-PCR methods were adopted to detect the protein and mRNA expression of ER-α and ER-β in cells after treated with low,medium and high concentrations of TSG (1×10-8, 1×10-6,1×10-4 mol/L)for 48 h. RESULTS :After treated with different concentrations of TSG for 24,48,72 h,the cell proliferation rate of each administration group at each time point (except for β-E2 group at 48 h)increased significantly ,compared with blank group ;those of TSG groups (1×10-5,1×10-6,1×10-7 mol/L)were significantly higher than β-E2 group(P<0.05 or P<0.01). After treated with low ,medium and high concentrations of TSG for 48 h,protein and mRNA expression of ER-α and ER-β in cells were increased significantly,compared with blank group (P<0.05 or P<0.01);protein expression of ER-β in TSG low concentration group ,mRNA expression of ER-α in TSG groups as well as mRNA expression of ER-β in TSG low and high concentration groups were significantly higher than β-E2 group(P<0.05 or P<0.01). CONCLUSIONS :TSG can induce the in vitro proliferation of T- 47D cells and exert estrogen-like effects by promoting protein and mRNA expression of ER-α and ER-β, which is stronger than that of β-E2 at a certain concentration.

ABSTRACT

OBJECTIVE: To investigate estrogen-like effect of tetrahydroxy stilbene glucoside (TSG) and its effects on the expression of estrogen receptor (ER) in uterus of sexually immature mice. METHODS: Totally 60 sexually immature Kunming mice were randomly divided into normal group, positive control group (estradiol valerate, 0.18 mg/kg), TSG low-dose and high-dose groups (50, 150 mg/kg), TSG low-dose and high-dose groups+estradiol valerate groups (same dose as medication alone group). Normal group was given constant volume of water intragastrically, and administration groups were given relevant medicine 0.2    mL/10 g, once morning and night, for consecutive 5 d. The uterus index and body weight increase of mice in each group were determined and calculated the next day after the last administration. The contents of serum estrogen (E2, LH, FSH) were determined by ELISA. HE staining was used to observe the morphology characteristics of uterus, and uterine tube diameter and endometrial thickness were detected. The expression of ER(ER-α and ER-β) in uterus was detected by immunohistochemical staining. RESULTS: The myometrium of the mice in normal group was parallel and compact, the epithelium of the uterus was columnar, and the expression of ER-α and ER-β was low. The uterine tube diameter, endometrium and epithelium of mice in each administration group increased, thickened or proliferated in varying degrees, and the expression of ER-α and ER-β changed. Compared with normal group, uterus indexes (positive control group, TSG high-dose group, TSG+estradiol valerate groups), the increase of body weight (positive control group, TSG high-dose groups, TSG low-dose+estradiol valerate group), uterine tube diameter and endometrial thickness (positive control group, TSG low-dose group, TSG+estradiol valerate groups), the expression of ER-α (positive control group, TSG+estradiol valerate groups) and the expression of ER-β (postive control group, TSG high-dose+estradiol valerate group)were increased significantly, while serum contents of LH (positive control group, TSG high-dose group) and FSH (TSG low-dose+estradiol valerate group) were decreased significantly (P<0.05 or P<0.01). The uterus index, uterine tube diameter, endometrial thickness and the expression in ER-α and ER-β of TSG+estradiol valerate groups, the increase of body weight and serum content of E2 in TSG low-dose+estradiol valerate group were significantly higher than same TSG dose alone groups (P<0.05 or P<0.01). The uterus index, uterine tube diameter, endometrial thickness and the expression of ER-α and ER-β in TSG groups, uterine tube diameter and the expression of ER-β in TSG+estradiol valerate groups, body weight increase of mice in TSG low-dose group were significantly lower than positive control group, while serum content of LH in TSG+estradiol valerate groups were significantly higher than positive control group (P<0.05 or P<0.01). CONCLUSIONS: TSG can increase uterus indexes and body weight of sexually immature mice to certain extent, regulate estrogen level, increase the diameter of uterine tube and endometrial thickness and up-regulate the expression of ER in the uterus, showing certain estrogen-like effect, which is weaker than that of estradiol valerate. Combined use of them may antagonize the effect of estradiol valerate.

ABSTRACT

OBJECTIVE: To study the effects of processed Polygonum multiflorum containing serum on the proliferation and the expression of estrogen receptor (ER) of human breast cancer T-47D cells, and to investigate its phytoestrogen (PE)-like effect. METHODS: Sexually immature SD rats were randomly divided into estradiol valerate (Ev) group (positive control, 0.12 mg/kg), processed P. multiflorum low-dose and high-dose groups (0.75, 3 g/kg, by crude drug), low-dose and high-dose processed P. multiflorum+Ev groups (same dose as single drug group), with 10 rats in each group. Blank group was given constant volume of water intragastrically, and administration groups were given relevant medicine intragastrically; once day and night, for consecutive 4 days. Two hours after last administration, blank serum and containing serum were prepared. T-47D cells were also randomly divided into blank group, Ev group, low-dose and high-dose processed P. multiflorum groups, low-dose and high-dose processed P. multiflorum+Ev groups, and then were cultured in medium which contained 20% blank serum or drug containing serum. CCK-8 assay was used to detect proliferation rate (PR). Western blotting assay and RT-PCR were used to detect the protein and mRNA expression of ER-α and ER-β. RESULTS: Compared with blank group, PR of administration groups [each administration group (24 h), other administration groups (48, 72 h) except for high-dose processed P. multiflorum+Ev group] were increased significantly; high-dose processed P. multiflorum group (72 h) was significantly higher than Ev group, and low-dose processed P. multiflorum+Ev group (72 h) was significantly higher than the same-dose processed P. multiflorum group; high-dose processed P. multiflorum+Ev group (72 h) was significantly lower than the same-dose processed P. multiflorum group (P<0.05 or P<0.01). Relative protein expression of ER-α in Ev group, high-dose processed P. multiflorum group and low-dose processed P. multiflorum+Ev group, relative mRNA expression of ER-α and protein expression of ER-β in administration groups, relative mRNA expression of ER-β in Ev group, low-dose processed P. multiflorum group and processed P. multiflorum+Ev groups were all increased significantly. Relative protein and mRNA expression of ER-α in Ev group were significantly higher than processed P. multiflorum groups and combination groups. Relative protein and mRNA expression of ER-β in Ev group were significantly lower than low-dose processed P. multiflorum+Ev group, but relative mRNA expression of ER-β was significantly higher than processed P. multiflorum groups and high-dose processed P. multiflorum+Ev group. Relative protein and mRNA expression of ER-α and ER-β in low-dose processed P. multiflorum+Ev group as well as relative mRNA expression of ER-β in high-dose processed P. multiflorum+Ev group were significantly higher than the same-dose processed P. multiflorum group. Relative protein and mRNA expression of ER-α in high-dose processed P. multiflorum+Ev group were significantly lower than the same-dose processed P. multiflorum group (P<0.05 or P<0.01). CONCLUSIONS: The processed P. multiflorum containing serum can promote the proliferation of human breast cancer T-47D cells, and play the PE-like role through promoting protein and mRNA expression of ER-α and ER-β. However, the above effects are weaker than estrogen, and the combination of the two may antagonize the effect of estrogen.

ABSTRACT

This study was aimed to prepare the spraying agent of prescriptions of Miao nationality herb and investigate the effect of Miao nationality herbs spray for serum SOD, MDA, and expression of Fas and Caspase-3 mRNA in lung tissues of silica-treated rats. The healthy SD rats were divided into 5 groups. Silica dust suspension was used in the model establishment of 4 groups. After the model was successfully established, 3 groups were randomly selected and given glucocorticoids atomization inhalation, Miao nationality herbs spray, Miao nationality herbs spray combined with intragastric administration of herbal medicine, respectively. After 40-day treatment, water-solubletetrazolium salt (WST-1) was used in the detection of serum superoxide dismutase (SOD). Thiobarbituric acid (TBA) was used in the detection of malondialdehyde (MDA). The mRNA expression variance of the Fas and Caspase-3 were detected by RT-PCR. The results showed that compared with the silica dust suspension group, the SOD activity of serum in the Miao nationality herbs spray group was significantly increased (P< 0.05). MDA content and the mRNA of Fas and Caspase-3 were significantly lower in the Miao nationality herbs spray group (P< 0.05). It was concluded that Miao nationality herbs spray group was able to increase the SOD activity of serum, decrease MDA content, and obviously decrease the expression of Fas and Caspase-3 of lung tissues among silica dust suspension rats.
