• Cytological Observation of Pollen Abortion of Lycium barbarum Haploids from Anther Culture

  Qing LUO;Bo ZHANG;Guoli DAI;Jianhua ZHAO;Youlong CAO;

  To reveal the sterility characteristics of Lycium barbarum haploids, cytological observations were made on the anthers of Ningqi No.1 and its haploids obtained from anther culture. The results showed that there were no significant differences in anther development between Ningqi No.1 and its haploids at the stage of pollen mother cell, and tetrads were formed successfully after the meiosis stage. The tetrads of Ningqi No.1 could release microspores. At the same time, the tapetal cells can provide nutrition for the development of the microspores, which eventually developed into mature pollen grains. Although the haploids could also release microspores at the tetrad stage, the tapetal cells degraded in advance, which made the released microspores unable to develop into mature pollen grains, resulting in pollen abortion of haploids.

  [Objectives] The protective effect of paeonol on DCM was further confirmed by observing the changes of myocardial structure and function in rats. [Methods] Rats were fed high-sugar and high-fat diet and injected intraperitoneally with streptozotocin(STZ) for two consecutive days to prepare animal model of type II diabetes. The model rats were randomly divided into model group, low-dose paeonol group(30 mg/kg), middle-dose paeonol group(60 mg/kg), high-dose paeonol group(120 mg/kg) and metformin group(157 mg/kg). The detected indicators included heart weight index(HWI), blood glucose(FBG), body mass, triglyceride(TG), and total cholesterol(TC). Myocardial pathological changes were observed by HE staining. The extent of myocardial fibrosis was observed by Masson staining. [Results] In the model group, the body weight of the rats declined significantly, and the phenomena of overdrinking, overeating and polyuria occurred. Compared with the model group, the body weight of rats in the paeonol treatment groups increased to different extents. Compared with the normal group, the HWI, FBG, LDH, AST, and TG increased in the model group, and decreased in different degrees in the paeonol treatment groups(P<0.05), suggesting that paeonol has certain protective effect on diabetic cardiomyopathy in rats. After HE staining and fixation, the myocardial tissue of rats was observed by optical microscope. The morphology of myocardial cells and myocardial fibers in the normal group were normal;Compared with the normal group, the model group has hypertrophy of myocardial cells, disordered arrangement of myocardial fibers, fiber breakage and dissolution, uneven staining between myocardial cells, and nucleus breakage or even disappearance;Compared with the model group, the pathological changes of myocardium in the paeonol treatment groups and DMBG group have been improved to different degrees. The arrangement of myocardial fibers is regular and the coloration is uniform. The results of Masson staining showed that in the normal group, and there was no significant increase of myocardial collagen fibers in the myocardial interstitium. Compared with the normal group, myocardial cells and interstitial collagen fibers(blue) in the model group were significantly increased. Compared with model group, myocardial collagen fiber hyperplasia in the paeonol treatment groups and DMBG group showed different degrees of improvement, among which the Pae-H group had the least blue bands and the most obvious improvement of collagen fiber. [Conclusions] Paeonol has different degrees of improvement effects on myocardial fibrosis in rats with diabetic cardiomyopathy, suggesting that paeonol has a protective effect on diabetic cardiomyopathy in rats.

  [Objectives] To study structural characteristics of Lycium ruthenicum community and soil properties on different types of desert rangeland in the lower reaches of Shiyang River, and provide theoretical basis for ecological protection and management in the lower reaches of Shiyang River. [Methods] One-way ANOVA analysis and correlation analysis were carried out with the aid of SPSS19.0 software for different types of desert rangeland soils. [Results](i) Among the communities surveyed, there are 31 species belonging to 9 families and 28 genera, including 12 shrub plants, 8 perennial herbs and 11 annual herbs. There are more single genus, occupying 50% of total genus. L. ruthenicum occupies an important position in the community with relatively higher importance value. It plays a dominated role in the community.(ii) In the soils with depths of 0-10 cm, 10-20 cm, 20-40 cm and 40-60 cm in different types of desert rangeland, the organic carbon contents in the saline alkali soil were the highest, with the values of 1.08%, 0.98%, 0.89% and 0.972%, respectively. Compared with that in sandy land, soil organic carbon in saline alkali land(0-10 cm) had the significant difference(P<0.05), available soil potassium in saline alkali land(except the depth of 20-40 cm) and the total phosphorus content in saline alkali land(0-10 cm) had the significant difference(P<0.05), the total soil nitrogen, alkali-hydrolyzable nitrogen, available phosphorus and the total potassium content had no significant difference(P>0.05). Soil organic carbon, available soil phosphorus in saline alkali land, total soil potassium on sand dune and total soil phosphorus in saline alkali land and gravel in different soil layers of the same type of desert rangeland had distinct aggregation effect.(iii) The soil microbial biomass in different types of desert rangeland displayed from high to low as saline alkali land > sandy land > fixed and semi fixed sandy land > gravel. The discrepancy of soil microbial biomass varied in different types of desert rangeland. The four soil enzyme activities in salinization was the highest. Soil invertase activity in saline alkali land in different soil layers were the highest. For different soil layers in the same type of desert rangeland, soil microbial biomass and invertase decreased gradually with the deepening of soil layer.(iv) There was a significant positive correlation between soil organic matter and microbial biomass carbon, microbial biomass nitrogen, phosphatase and sucrase(P<0.01), and a significant positive correlation with urease and catalase(P<0.05). Phosphorus content was significant positively correlated with urease, phosphatase and invertase(P<0.01), and positively correlated with microbial biomass carbon(P<0.05). Soil available potassium content was significant positively correlated with microbial and phosphatase(P<0.01). [Conclusions] The species of L. ruthenicum community and soil properties on different types of desert rangeland in the lower reaches of Shiyang River clearly shows that most species belong to a few families, and a few species belong to most families, and many species are single genus or single family. Soil organic carbon, soil available phosphorus, total phosphorus, soil microbial biomass and enzyme activity in salinization land had distinct surface aggregation effects, so salinization land provides excellent growth environment for the growth of L. ruthenicum, which is of great significance for the protection of L. ruthenicum population.

  Xiaoyu ZHANG;Xianjing ZHENG;Hongrui XIA;Longru SUN;

  [Objectives] To study the anti-inflammatory activity and mechanism of salvianolic acid A(Sal A), salvianolic acid C(Sal C), and rosmarinic acid(RA) on HAECs induced by TNF-α. [Methods] VE was used as a positive control and TNF-α induced human aortic endothelial cells(HAECs) were selected as the inflammation model cells. The levels of IL-6, MCP-1 were determined using ELISA. The mRNA levels of IL-6, MCP-1, ICAM-1, P-selectin and NF-κB were analyzed by quantitative RT-PCR. The protein expression of NF-κB was determined by western blot. The adhesion of U937 to HAECs was assessed by BCECF/AM labeling assay. Immunohistochemistry detection was used for ICAM-1 and P-selectin expression levels in TNF-induced HAECs, and DHE detection for the ROS production in HAECs induced by TNF-α. [Results] TNF-α-induced over-expressions of IL-6, MCP-1, NF-κB, ICAM-1 and P-selectin in HAECs were down-regulated by Sal A, Sal C and RA both in mRNA or protein levels, respectively. Meanwhile Sal A, Sal C and RA could significantly inhibit the production of ROS and U937 cells adhesion to HAECs. [Conclusions] Phenolic acids could inhibit TNF-α-induced inflammatory responses on HAECs and the mechanism might be related to inhibition of the production of ROS and blocking NF-κB signaling pathway.
