Objective To investigate the relationship between hyponatremia(HN) and the plasma level of C-type natriueetic peptide(CNP) in patients with hypertensive intracerebral hemorrhage(HICH).Methods Radioimmunoassay was applied to determine the plasma concentrations of CNP in 36 patients with HICH and the concentrations of serum sodium were measured.Results The mean plasma level of CNP in 6 cases with HN(24.6?3.98 mg/ml ) was significantly increased compared with that in 26 cases without HN(21.1?3.23 mg/ml)( P

Objective To research the connection between the sagittal orientation of facet joints and disc degeneration in lumbar spine and to investigate the contribution of which to development the degenerative spondylolisthesis. Methods A new effective CAD method was used to accurately establish 9 finite element models(FEM)which were assembled respectively with facet-joint angle 65?, 45?, 25?, with normal disc, light degenerative disc and severe degenerative disc. The biomechanical parameters of 9 finite element models were measured under axial compressive load within physiological range. Results Compared with FEMs with facet-joint angle 45? and 25?, anterior displacement of L4 vertebra in FEMs with facet-joint angle 65? was increased, where the maximum von Mises stresses on facet surface, isthmus and the contact force on facet surface in horizontal orientation were obviously increased. Meanwhile, FEMs with facet-joint angle 65? showed a decrease in end-plate bulge and an increase in stress of annular matrix. The stiffness in light degenerative disc FEMs was reduced and the von Mises stresses on facet surface and isthmus was slightly increased compared with the normal disc FEMs. Among all, the FEM with facet-joint angle 65? combined with light degenerative disc showed the poorest resisting anterior shear force. Conclusion Sagittal orientation of facet joints is not only the primary inducement of the degenerative spondylolisthesis but the secondary pathological change of remodeling of the facet-joints induced by the regional stress change. The inherent instability of lumbar motion segment of sagittal orientation of facet joints is influenced by the lumbar disc degeneration. The lumbar disc degeneration has no manifested contribution to the aggravation of the sagittal orientation of facet joints.

Objective To evaluate the alteration of CD4+ regulatory T cells in peripheral blood from patients with ankylosing spondylitis(AS). Methods Seventy-eight AS patients and 50 healthy individuals were included in this study. The proportion of CD4+CD25+CD127lo/- T cell population in CD4+ T cells as well as that cytotoxic T lymphocytes(CTL) and NK cells in lymphocytes was evaluated by flow cytometry. Serum TGF-β and TNF-α were measured by ELISA. The inhibitory function of CD4+CD25+ regulatory T cells was measured by mixed lymphocyte culture. Results The population of CD4+CD25+CD127lo/- T cells in peripheral blood of AS patients accounted for (4.36±1.21)% of CD4+ T lymphocytes, which was significantly lower than that in healthy individuals (P<0.05). The CD4+CD25+CD127lo/- T cells population in AS patients was positively correlated with TGF-β level, but negatively with TNF-α. Compared with healthy individuals, the function of CD4+CD25+ regulatory T cells in the inhibition of alloreactive T cells was lower in AS patients, which was related to the decreased secretion of TGF-β. Conclusion The CD4+ regulatory T cells in peripheral blood of AS patients are significantly decreased and its function is defective, which leads to immune regulatory dysfunction in vivo. It may be one of immune pathogenesis mechanisms of AS.

BACKGROUND:In esophageal cancer chemotherapy, inhibiting proliferation of tumor cels and tumor stem cels can be effectively improved by using appropriate sensitive agents.
OBJECTIVE:To explore the effect of molybdenum on ECA-109 cel chemosensitivity and p75NTR cel inhibition in esophageal carcinoma cels.
METHODS:ECA-109 cels at logarithmic phase were selected and randomly divided into blank control group, cisplatin group, molybdenum group and molybdenum+cisplatin group (combination group). Molybdenum and cisplatin at different concentrations were used in the three groups. MTT assay was used to detect ECA-109 cel proliferation and growth; flow cytometry was used to detect the proportion of P75NTR cels.
RESULTS AND CONCLUSION:Cisplatin at different concentrations showed a certain inhibitory role in ECA-109 cels, which had an increasing kiling effect on esophageal carcinoma stem cels at dose- and time-dependent manner. Molybdenum alone had no remarkable kiling effects on inhibiting ECA-109 proliferation and esophageal carcinoma stem cels. Combination of molybdenum and cisplatin was found to have an enhanced effect to inhibit ECA-109 cels and to kil esophageal carcinoma stem cels in a dose- and time-dependent manner, which was significantly different from the cisplatin group and blank control group (P < 0.05). These findings indicate that molybdenum can promote and enhance the inhibitory effect of cisplatin on ECA-109 and p75NTR cels, which can be used as a chemosensitizer.
