In this experiment, 4 varieties of Chinese milk vetch (Xinyang, Minzi No. 6, Minzi 8487711, and Shishou) were used as host plants and inoculated with 3 strains of rhizobium (CCBAU 2609, M. h 93, and 7653R). The differences in their morphology, yield, and nodule characteristics at different growth stages were studied and the reasons for these differences were analyzed to explore the exclusivity between different varieties of Chinese milk vetch and strains of rhizobium. Results showed no significant difference in plant height and whole-plant dry weight at seedling stage under different treatments but significant differences in these characteristics at full flowering stage. The results indicated that Minzi 8487711 and Shishou were significantly better than the other varieties. During the whole growth period, the growth indexes and nodule characteristics of the 4 varieties inoculated with strain 7653R were better than those of the varieties inoculated with other strains. At full flowering stage, compared with that of the control group, the biomasses of Xinyang, Minzi No.6, Minzi 8487711, and Shishou had increased by 2.04, 2.84, 1.56, and 2.69-fold, respectively, and nitrogenase activities increased by 3.82, 9.60, 6.21, and 15.18%, respectively. Significant differences in the exclusivity between varieties and strains were observed. Minzi No.6–7653R and Shishou variety–7653R had the strongest exclusivity. The results showed that 7653R was a broad-spectrum and high-efficiency rhizobium strain. 7653R is recommended to be used in combination with Chinese milk vetch varieties, such as Minzi 8487711 and Shishou, to obtain advantages in yield and nitrogen fixation in production.

Bone is a complex tissue consisting of cells and matrix. Mass and thick bone mass has a dynamic addition and subtraction through the process of remodeling (bone matrix absorbed and formed again). Bone is formatted by osteoblast cell and resorption by osteoclast cell. Osteoblasts produce a matrix of osteoid, which is composed mainly of type I collagen, and osteoclast removes bone tissue by removing its mineralized matrix and breaking up the organic bone. Bone remodeling purpose to defend shape and structure of bone. the purpose of this study is to prove that submaximal-intensity exercise and salmon calcitonin improve bone density in growing rat this research method uses design of the randomize posttest only control group design. We compered femur bone density in 24 male norvegicus rats aged 6 weeks that were divided into 4 groups: controls, calcitonin, exercise, combine. Exercise group swam 3 times a week in submaximal intensity, calcitonin group injected synthetic salmon calcitonin 2 iu /100 gram of rat weight every day and combine group did both of it. After 8 weeks, rat femur bone density measured using ultrasound. the result: there are significant differences in bone density between group 1 (control) and group 4 (combine) with p = 0.001, thus the p value <0.05 indicates that there is a significant difference to the average density in both groups. While comparisons to other groups found no significant difference because the value of p> 0.05. the benefits of this research are calcitonin salmon and submaximal-intensity exercise increase the density bone in the growth period. High bone density is mean the bone is strong and health, not porous and fragile so decrease bone fracture risk. increase the bone density in of growth period make the bone get the best mass, and avoid from early osteoporosis.

Objective: To observe the clinical efficacy of sequential butylphthalide therapy combined with dual antiplatelet therapy in the treatment of elderly patients with acute cerebral infarction (ACI). Methods: One hundred and twenty-two elderly patients with ACI who were admitted to the department of neurology of our hospital at May 2016-August 2018 were selected grouped into a control group and an observation group by random number table method, 61 in each group. On the basis of conventional treatment, the patients in the control group were given dual antiplatelet therapy (aspirin enteric-coated tablets + clopidogrel bisulfate tablets), while the patients in the observation group were given sequential butylphthalide therapy on the basis of the control group. The clinical effects of the two groups were compared after four weeks of treatment, and the changes of National Institutes of Health Stroke Scale (NIHSS), ADL score, plasma 3-mercaptopyruvate sulphurtransferase (3-MST) and Amyloid β42 (Aβ42) levels and the occurrence of adverse reactions during treatment were recorded. Results: The clinical efficacy of the observation group was better than that of the control group (P<0.05). There was no significant difference in NIHSS and ADL scores between the two groups before treatment (P>0.05). After treatment, the NIHSS and ADL scores of the observation group were better than those of the control group (P<0.05). There was no significant difference in plasma levels of 3-MST and AB42 between the two groups before treatment (P>0.05). The level of plasma 3-MST in the observation group was higher than that in the control group, and the level of plasma Aβ42 was lower than that in the control group (P<0.05). No serious adverse reactions occurred during the treatment period in both groups. Conclusion: Butylphthalide sequential therapy combined with dual antiplatelet therapy is effective in the treatment of elderly ACI. It can effectively improve the plasma level of 3-MST and decrease the plasma level of Aβ42, which is conducive to improving the living ability and neurological function of patients and has high safety. doi: https://doi.org/10.12669/pjms.36.4.1831 How to cite this:Wo X, Han J, Wang J, Wang X, Liu X, Wang Z.

Members of Brassicaceae have been frequently cited as allelopathic crop. The toxic effect of Brassica spp. may be caused by hydrolysis products of glucosinolates that occur in substantial amounts in the vegetative parts of Brassica spp. This study investigated the allelopathic potential of Brassica napus, B. rapa and B. juncea on the sunflower seed germination and seedling growth. Aqueous extracts of three species from two stages (full flowering and straw) of sampling were separately made with 0 (distilled water), 10, 20, 30 and 40% concentrations. This experiment was conducted in 2 &times; 3 &times; 5 factorial arrangement based on completely randomized design with five replications. There was a highly significant difference among different concentrations of extracts and also between two stages of extraction. All aqueous extracts significantly affected sunflower germination, germination rate, seedling root and hypocotyl length, fresh and dry matter weight when compared with distilled water control. The greatest concentration showed a stronger inhibitory effect. Root length was more sensitive to extracts than hypocotyl length.

Abstract Objective: To determine if an increase in tooth contacts is the principal effect of tooth positioner wear. Materials and Methods: Patient charts from a consecutive series were reviewed until a sample of 100 cases that used a tooth positioner was obtained. One hundred control cases were randomly selected from patients treated at the same period. Malocclusion severity and finished occlusion were assessed with the American Board of Orthodontics (ABO) Discrepancy Index (DI) and Objective Grading System (OGS) score, respectively. Finish casts for each patient were mounted on a Galleti articulator. Occlusal registrations were obtained with silicone-based impression material from casts fabricated from impressions taken at the time of fixed appliance removal (control) or at the end of the tooth positioner treatment (experimental). The number of the perforations and transparent areas on the occlusal registrations were quantified. Results: There was no significant difference (P = .20) in the number of total occlusal contacts between the two groups. However, the OGS score of the tooth positioner group (16.7) was significantly (P = .0009) better than for the control group (19.9). Conclusions: Tooth positioners were effective in improving the occlusal finish, but the effects were independent of an increase in occlusal contacts. Positioners primarily improved first order alignment by tipping teeth into an improved intercuspation.

Competitive interactions between spring wheat and spring barley were traced based on a pot experiment. In the years 2003-2004, three cycles of the experiment were carried out in a greenhouse. Two spring cereals - wheat and barley, sown in a mixture and in a monoculture, with different mineral fertilisation levels, were the object of evaluation and comparison. The experiment was set up according to the additive scheme, determining dry weight values for both species in 5 growth stages (emergence, tillering, shooting, heading and ripening). Results were used to determine relative yields and competition ratios. It was demonstrated that competition between the cereals started already from the emergence stage and lasted till the end of vegetation, manifesting itself with the greatest strength at the heading stage, but thereafter it weakened in the NPK poorer environment. Access to a larger pool of macroelements resulted in the intensification of competitive interactions. Spring barley used the limited growth factors better than wheat from shooting till the ripening period, and a reverse relation was exhibited only at the tillering stage.
