Objective To investigate the effects of seed sources and storage conditions on the seed germination rate of Valeriana officinalis. Methods The seeds of V. officinalis under different storage conditions were used as materials for germination test, and the germination rate was calculated and compared according to the results. Results The seed germination rate of valerians is varied with different sources. The seed germination rate of V. officinalis is higher than that of V. officinalis var. latifolia, and the seed germination rate of cultivated valeriana is much higher than that of the wild plant. The storage periods, storage temperature, and germination conditions also affect the germination rate. Conclusion To maintain the seed germination rate, the seed of V. officinalis should be stored in conditions with ventilation and at suitable low temperature. Lower temperature helps to prolong the seed life with relatively high germination rate. Valeriana seed should also be propagated at available temperature conditions in proper seasons.

Objective To observe the effects of Sanjia Yigan Granule (S-JG) on hepatic fibrosis and explore its mechanism related to anti-lipid peroxidation in rats. Methods Forty male SD rats were randomly divided into four groups: normal group, model group, and compound Salviae Miltiorrhizae (Sm) group and S-JG group. Dimethylnitrosamine was injected intraperitoneally for 4 weeks to induce hepatic fobrosis. At the same time of modeling, Sm and S-JG were given in the corresponding groups. The rats were killed after four weeks. The histomorphylogic structure of the liver tissues was observed under optical microscope; the levels of MDA and SOD in serum were determined by radioimmunoassay. Results Compared with those in normal group, the collagen area in Masson staining and level of serum MDA were inreased obviously, and the level of serum SOD was dereased obviously in model group (P

OBJECTIVE: To investigate the effects of Liriope platyphylla total saponin (LPTS) on learning, memory, neuromediators and metabolites in aging mice induced by D-galactose. METHODS: Ninety Kunming mice were randomly divided into nine groups: normal saline (NS)-treated group, untreated group, high- (100 mg/kg), medium- (50 mg/kg) and low-dose (10 mg/kg) LPTS-treated groups, Shuxuening-treated group, jiaogulanosidi-treated group, flunarizine-treated group and vitamin E-treated group. The Kunming mice in the NS-treated group were administered with NS by intraperitoneal injection, while the aging mice in the other eight groups were administered with D-galactose by intraperitoneal injection. At the same time, the aging mice in different groups were fed with corresponding drugs for 42 days, and the aging items of the mice in different groups were measured, respectively. RESULTS: LPTS could improve the memory of aging mice induced by D-galactose, promote its body weight, and increase the thymus and spleen indexes of the aging mice. LPTS could decrease the levels of MDA and lipofuscin, inhibit MAO activity and increase SOD activity and GSH-Px level. CONCLUSION: LPTS may improve the ability of learning and memory and delay aging.

OBJECTIVE: To investigate the prevention effect of aqueous extract of Epimedii sagittatum (ESE) on ovariectomy-induced (OVX) bone loss in rats. METHODS: Rats were divided into sham-operated and OVX groups. The OVX rats were divided into four groups treated with distilled water, 17beta-estradiol (1 mg/kg, ig) and ESE (0.5 and 1 g/kg, ig) for 11 weeks. Serum calcium, phosphorus, estradiol, bone gla protein concentrations and serum alkaline phosphatase activity were measured. Bone density was assayed by dual-energy X-ray absorptiometry. The undecalcified longitudinal proximal tibial metaphysical sections were cut and stained for the bone histomorphometric analysis. RESULTS: In OVX rats, alkaline phosphatase activity in serum was markedly increased by ESE treatment, which had no obvious influence on the body weight. Meanwhile, atrophy of uterus and descent of bone mineral density were suppressed by ESE treatment. In addition, ESE completely corrected the decreased concentrations of calcium and E2 in serum observed in OVX rats. Histological results also showed ESE prevented the increases in trabecular separation (Tb.Sp) in OVX rats whereas it did not alter trabecular thickness (Tb.Th) and trabecular number (Tb.N) in OVX rats. Moreover, ESE had remarkable effect on bone formation rate with bone volume as referent (BFR/BV) and bone formation rate with bone surface as referent (BFR/BS). CONCLUSION: The findings assessed on the basis of biochemical test, bone mineral density and histomorphometric parameters show that aqueous extract of Epimedii sagittatum has a definite antiosteoporotic effect and can prevent the OVX-induced bone loss in rats.

Objective: To study the effects of TCFC on proliferation and osteogenic action of osteoblast in neonatal rat calvaria cultures in vitro. Methods: Osteoblasts were isolated from neonatal rat calvaria through trypsin and collagenase digestion. The proliferation and collagen synthesis were assayed by 3H TdR and 3H proline incorporation. The activity of ALP was measured by p nitrophenyl sodium phosphate assay. The ipriflavone was used as positive control drug.Results: TCFC significantly promoted bone cell proliferation, alkaline phosphatase activity and collage synthesis.Conclusion: TCFC had the anti osteoporosis action by promoting osteoblast proliferation, ALP activity and collage synthesis.

Objective:This study compares the magnetic resonance imaging (MRI) appearance of two types of breast tissue markers to investigate the appropriate clinical application of the markers.Methods:Breast MRI of 69 patients (78 masses) with breast tissue markers had been placed were analyzed retrospectively from November 2015 to August 2018 in our hospital. The sizes and shapes of breast tissue markers were assessed in axial fat-suppressed T2-weighted images, T1-weighted images and contrast-enhanced T1-weighed images.Results:The length of the coil nickel-free stainless steel markers were greater than ribbon titanium markers, with statistical difference in fat-suppressed T2-weighted images ( P=0.039). In contrast-enhanced T1-weighted images, all coil nickel-free stainless steel markers showed >6 mm diameter and round shape, and ribbon titanium markers showed >6 mm diameter ( n=20) or ≤6 mm diameter ( n=8), and round ( n=20), dot ( n=7) or band ( n=1) shapes. The categories of sizes and shapes in two types of breast tissue markers both had statistical significance ( P<0.001, P<0.001). Conclusions:Small breast lesions with breast tissue markers are not suitable for MRI evaluation. The artifact of ribbon titanium markers is smaller than coil nickel-free stainless steel markers, so they have less impact for lesions. The choice of the breast tissue markers and image evaluation methods should depend on the different clinical conditions.
