ABSTRACT

Objective:To explore the antidepressant mechanism of Yinxing Mihuan oral solution (YMO) by investigating its effect on depression model rats. Method:The depression rats were induced by isolation combined with chronic unpredictable mild stress (CUMS) and then randomly divided into model group, fluoxetine group (10 mg·kg<sup>-1</sup>) and high-dose (618 mg·kg<sup>-1</sup>) and low-dose (309 mg·kg<sup>-1</sup>) YMO groups. A blank control group was also set up and ten rats were included in each group. Modeling lasted for 21 consecutive days, and rats were administered the 8th day after stimulation at a dose of 10 mL·kg<sup>-1</sup> for 14 days, except those in the blank control and model groups which were given distilled water. Afterward, the sucrose preference test, open field test, tail suspension test were carried out. The pathological changes of hippocampus in depression rats were observed after hematoxylin-eosin (HE) staining. The content of interleukin-1<italic>β </italic>(IL-1<italic>β</italic>), interleukin-6 (IL-6) and tumor necrosis factor-<italic>α </italic>(TNF-<italic>α</italic>) in the hippocampus of rats in each group and the expression of NOD-like receptor 3 (NLRP3) and other proteins in its related activation signaling pathways were detected with multi-factor detection (Luminex) and Western blot. Result:After 14 days of continuous administration, compared with the blank control group, the model group witnessed significantly reduced sugar water consumption rate and the times of rearing and significantly prolonged cumulative time of immobility during tail suspension (<italic>P</italic><0.05, <italic>P</italic><0.01). Compared with the model group, the fluoxetine group and the high-dose YMO group saw increases in the times of rearing, times of crossing and sugar water consumption rate and a significant decrease in the cumulative time of immobility during tail suspension (<italic>P</italic><0.05, <italic>P</italic><0.01). The results of HE staining showed that the neurons in the hippocampus of rats in the high-dose YMO group were arranged in order and slightly loosened, without obvious microglia infiltration observed. The levels of IL-1<italic>β</italic>, IL-6 and TNF-<italic>α</italic> in the hippocampus of the model group increased significantly as compared with the blank control group (<italic>P</italic><0.05, <italic>P</italic><0.01), and their content in the high-dose YMO group was significantly lowered in the comparison with the model group (<italic>P</italic><0.05, <italic>P</italic><0.01). Molecular biology experiments demonstrated that compared with the results of blank group, the expression of purinergic receptor P2X7 (P2RX7), NLRP3, apoptosis-associated speck-like protein (ASC), Caspase-1 and IL-1<italic>β</italic> remarkably increased in the model group (<italic>P</italic><0.05, <italic>P</italic><0.01). Additionally, the expression of P2RX7, NLRP3, ASC, Caspase-1 and IL-1<italic>β </italic>was significantly inhibited in the fluoxetine group and the high-dose YMO group compared with the model group (<italic>P</italic><0.05, <italic>P</italic><0.01). Conclusion:YMO can improve the depression-like behaviors of rats induced by isolation combined with CUMS, and its mechanism of action is related to the regulation of the P2RX7/NLRP3 signaling pathway.

ABSTRACT

Objective:To establish a mouse model of diminished ovarian reserve (DOR) induced by tripterygium wilfordii polyglycosides (TWP), and to explore the therapeutic effect of Dingkundan (DKD) on DOR, so as to provide scientific basis for its clinical application. Method:The 60 female Blab/c mice with regular estrous cycle were randomly divided into blank group, model group, low,medium and high-dose DKD group, DKD group and estradiol valerate group, with 10 mice in each group. Except the blank group, the other groups were given 40 mg·kg-1 TWP suspension. Meantime,low,medium and high-dose DKD group were given 1.64,3.28,6.56 g·kg-1 DKD suspension respectively, and estradiol valerate group was given 0.15 mg·kg-1 estradiol valerate suspension by gastric lavage once a day for 30 days. The general condition, body weight, estrous cycle and gonad index of mice were observed, serum follicle-stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E2) were determined by radioimmunoassay, ovarian morphology and follicle count were observed by hematoxylin-eosin staining (HE) staining. Result:Compared with the blank group, most of the mice in model group had disordered estrous cycle, uterine and ovarian indexes decreased (P<0.05), serum FSH increased (P<0.05), LH was on an upward trajectory, E2 was on a downward trend, and the number of growth follicles and corpus luteum decreased and the number of atresia follicles increased(P<0.05). Compared with the model group, half of the mice in DKD group resumed regular estrous cycle, however, the estrous cycles of mice in estradiol valerate group were stagnated during estrous period. In medium-dose, high-dose DKD group and estradiol valerate group, the uterine and ovarian indexes of the mice were increased, the serum FSH value decreased (P<0.05) and serum LH was on a downward trend, high-dose DKD group and estradiol valerate group increased the levels of serum E2 (P<0.05). In DKD group, the number of growth follicles and corpus luteum were increased and the number of atresia follicles were reduced (P<0.05), with the best effect at medium dosage. And in estradiol valerate group, the number of primitive follicles, sinusoidal follicles and corpus luteum were increased (P<0.05), but the number of atresia follicles had no difference to the model group. Conclusion:DKD can improve serum sex hormones, promote follicular development and reduce follicular atresia, which can play a therapeutic role in the treatment of DOR.

ABSTRACT

Objective:To observe the anti-inflammatory effect and its mechanism of Euphorbiae Ebarcteolatae Radix bacteriostasis ointment in eczema mice induced by 2,4-dinitrochlorobenzene (DNCB). Method:A total of 40 ICR adult mice were randomly divided into control group,model group,hydrocortisone Butyrate cream group (0.09g·kg-1) and Euphorbiae Ebarcteolatae Radix bacteriostasis ointment group (0.09 g·kg-1), with 10 mice in each group. Except for the normal group, other groups were given DNCB to induce the chronic eczema model. Twenty-four hours after DNCB stimulation, they were given the corresponding drugs through auricle and back, twice a day for 10 days. After drug intervention, efforts were made to measure the change of thickness and weight of the middle ear, assess the allergic effect, and calculate the spleen index of the mice. Optical microscope was used to observe the pathological changes in ear tissues of mice. And the levels of serum interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), interleukin-2 (IL-2), interleukin-4 (IL-4) in mice were determined by multiplex immunoassay. Result:Compared with control group, the thickness and weight of right ears, score of allergic effect, spleen index and the levels of IL-2 and IL-4 in serum showed significant increases in model group (P<0.05,P<0.01). The histopathology injuries of ear were aggravated. Compared with model control group, Euphorbiae Ebarcteolatae Radix bacteriostasis ointment could reduce ear thickness and score of allergic effect, regulate the spleen index, decrease the inflammation factor in serum such as IL-2 and IL-4 (P<0.05,P<0.01), and improve ear histopathology injuries. Conclusion:Euphorbiae Ebarcteolatae Radix bacteriostasis ointment may have a good effect on eczema.

ABSTRACT

To evaluate clinical studies on effect of traditional Chinese medicines in treating ovulatory disorder infertility by using evidence-based medical method. According to the standard of Cochrane Handbook, the selection standard of the randomized controlled clinical trail on kidney-tonifying and blood-activating traditional Chinese medicines in the treatment of ovulatory disorder infertility was formulated. Literatures in line with the standard were searched through computers among Chinese and English databases. The literatures included were evaluated by evidence-based medicine method, and analyzed with Revman 5. 1. There were 19 articles in line with the standard. Data for pregnancy rate, ovulation rate and miscarriage rate was extracted from them, and heterogeneity test was conducted with Meta, which showed no statistical heterogeneity. Results showed pregnancy rate (n = 17) , RRp 1. 66, 95% C1 [1. 45, 1.92], Z7.06 (P<0.000 01); ovulation rate (n =11) , RRo 1.05, 95% CI[0.97,1. 12], Z 1.25 (P=0.21); miscarriage rate (n =5) , RRM, 0. 24, 95% CI[0. 11,0. 56] , Z 3.33 (P =0. 000 9). After analysis and comparison, it is found that the Chinese medical treatment group was superior to the Western medicine control group in terms of pregnancy rate, which showed statistic significance. Both groups showed no obvious difference in the ovulation rate, and no statistic significance; the miscarriage rate of the Chinese medicine group is obviously lower than that of the Western medicine control group, which indicated statistic significances. This study preliminarily proves the good efficacy and unique advantages of kidney-tonifying and blood-activating traditional Chinese medicines in treating ovulatory disorder infertility.
