ABSTRACT

ObjectiveTo explore the regulatory effect of Gouqi chewable tablets on innate and adaptive immunity in normal mice and its antioxidant activity in vitro and in vivo. MethodThe effects of low-, medium-, and high-dose groups (0.25, 0.5, 1.5 g·kg-1) on the immune function of normal mice were observed by carbon clearance test, immune organ index test, serum hemolysin test, ConA-induced splenic lymphocyte proliferation test, and natural killer cell (NK cell) activity test. The effects of Gouqi chewable tablets on the antioxidant capacity in vivo were determined by detecting the content of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and malondialdehyde (MDA) in mice serum. The in vitro antioxidant activity of Gouqi chewable tablets was detected by 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS), 2,2-diphenyl-1-picrylhydrazyl (DPPH), and hydroxyl radical scavenging tests. ResultCompared with the blank control group, the low-, medium-, and high-dose groups of Gouqi chewable tablets improved the viability of NK cells, the proliferation of splenic lymphocytes, and the level of serum hemolysin antibody in mice (P<0.05). The high-dose group increased the thymus index, spleen index, and phagocytic function of macrophages (P<0.05, P<0.01). As compared with the blank control group, the activity of GSH-Px in mice serum in the medium-dose group was increased (P<0.05), and the content of MDA in mice serum in the high-dose group was decreased (P<0.05). In in vitro antioxidant tests, the median inhibitory concentration (IC50) values of Gouqi chewable tablets were 1.64±0.20, 2.04±0.03, and 10.27±0.03 g·L-1 by the DPPH, ABTS, and OH- free radical method, respectively. Those results indicated that Gouqi chewable tablets have good antioxidant effects in vitro. ConclusionGouqi chewable tablets can enhance the immune function of mice with good antioxidant effects.

ABSTRACT

Objective:To observe the effect of Dingkundan in adjuvant treatment of clinical symptoms, quality of life, immune function and prognosis of patients with radiotherapy and chemotherapy after endometrial carcinoma (EC) operation. Method:Patients were divided into control group (82 cases) and observation group (86 cases) according to random number table. A total of 75 patients in control group completed the study (4 patients fell off or lose visit, and 3 patients were eliminated), while 77 patients in observation group completed the study (5 patients fell off or lose visit, and 4 patients were deleted). After operation, patients got brachytherapy, external pelvic irradiation and chemotherapy. Patients in control group got Bazhenwan, 1 pill/time, 2 times/day, and those in observation group got Dingkundan, 7 g/time, 2 times/day. The course of treatment lasted for 4 months, and long-time follow-up data was recorded. Before treatment, and at the second and fourth month after treatment, deficiency of Qi and blood was scored. Toxic reactions after radiotherapy and chemotherapy were recorded, and incidence rate of acute and advanced radiation injury of bladder and rectum and toxicity of chemotherapeutic drugs at grade 3 or above grade 3 level were compared. And levels of T lymphocyte subsets (CD3<sup>+</sup>, CD4<sup>+</sup>, CD8<sup>+</sup> and CD4<sup>+</sup>/CD8<sup>+</sup>) were detected, European collaborative quality of life Cancer Core Scale (EORTC QLQ-C30) was evaluated, and expressions of pce125 (CA125), epididymis protein 4 (HE4), Dickkopf-related protein-1 (DKK1), vascular endothelial growth factor (VEGF), matrix metalloproteinase-9 (MMP-9) and transforming growth factor-<italic>β</italic><sub>1</sub> (TGF-<italic>β</italic><sub>1</sub>) were tested before and after treatment. The follow-up was made for every three months, and the progression (recurrence/metastasis) of patients was recorded. Result:Scores of deficiency of Qi and blood in observation group were lower than those in control group at the second and fourth week after treatment (<italic>P</italic><0.01). Incidence rates of acute and advanced radiation injury of bladder and rectum and toxicity of chemotherapeutic drugs at grade 3 or above grade 3 level and incidence rates of bone marrow suppression, gastrointestinal toxicity, neurotoxicity were lower than those in control group (<italic>P</italic><0.05). Five functional dimensions and overall quality of life score based on EORTC and QLQ-C30 in observation group were higher than those in control group (<italic>P</italic><0.01), and scores of three symptom dimensions were lower than those in control group (<italic>P</italic><0.01). Levels of CD3<sup>+</sup>, CD4<sup>+</sup> and CD4<sup>+</sup>/CD8<sup>+</sup> were higher than those in the control group (<italic>P</italic><0.01), and CD8<sup>+</sup> was lower than those in the control group (<italic>P</italic><0.01). Levels of CA125, HE4, DKK1, VEGF, MMP-9 and TGF-<italic>β</italic><sub>1</sub> were lower than those in the control group (<italic>P</italic><0.01). The disease progression rate in observation group was 18.18% (14/77), which was lower than 33.33% (25/75) in control group (<italic>χ</italic><sup>2</sup>=4.572, <italic>P</italic><0.05). Conclusion:In adjuvant treatment of patients with radiotherapy and chemotherapy after EC operation, Dingkundan can reduce the symptoms of Qi and blood deficiency syndrome and side effects caused by radiotherapy and chemotherapy, improve the quality of life and immune function, inhibit the expression of tumor markers and tumor growth factor, delay the progression of tumor and improve the prognosis.

ABSTRACT

When the glomerular mesangial cells of rats were cultured in vitro at high glucose concentration,the activity of extraeellular signal-regulated kinase(ERK),the expression of transforming growth factor-?_1(TGF-?_1)mRNA and the content of typeⅣcollagen in the supematant were higher than those at normal glucose concentration.These effects were inhibited by fluvastatin.The results showed that the activation of ERK signal transduction pathways appeared to play a role in the onset and progression of diabetic nephropathy. Furthermore,fluvastatin could protect the kidney by inhibiting ERK signal transduction pathway and TGF-?_1 expression.
