ObjectiveTo study the effect of different treatment on prolapse of lumbar intervertebral disc. Methods 169 patients with prolapse of lumbar intervertebral disc were divided into two groups, the contral group treated with traction and massage, and the comprehensive group treated with acupuncture, physical therapy, and phsiotherapy besides traction and massage. The assessment included index and rate in improvement and efficiency of rehabilitation. Results The index and rate in improvement and efficiency of rehabilitation is better in the comprehensive group than in the contral group. The course of treatment in the comprehensive group is shorter than that in the contral group.

BACKGROUND:With the continuous development and progress of medical model, the treatment and rehabilitation recovery from peripheral nerve defects needs higher requirements; therefore, stem cel culture-based nerve tissue engineering technology provides a new strategy for nerve defect repair. OBJECTIVE:To explore the feasibility of combining bone marrow mesenchymal stem cels and new nerve conduits to repair peripheral nerve defects. METHODS:Fifty New Zealand white rabbits, clean grade, were randomly divided into experimental group and control group, with 25 rabbits in each group. Animal models of peripheral nerve defects were made about 15 mm distant to the middle segment of the radius of the rabbit foreleg. At 1 week after modeling, bone marrow mesenchymal stem cels/new nerve conduit composite material was implanted into the defect in the experimental group; and in the control group, only bone marrow mesenchymal stem cels were transplantation. At 4 weeks after transplantation, a 5-mm nerve fiber was taken from the defect site, stained with hematoxylin-eosin and observed under scanning electron microscope. Density and diameter of regenerated nerve fibers were compared between the two groups. RESULTS AND CONCLUSION:Compared with the control group, the density of nerve fibers was significantly higher in the experimental group, but the diameter of nerve fibers was significantly lower (P < 0.05). There were more cels with good growth, large size and many processes on the surface of regenerated nerve tissues in the experimental group than the control group. Moreover, in the experimental group, interconnected cels were woven into a mesh and the axons were longer and thicker, both of which were the performance of typical neuron-like cels. Taken together, the bone marrow mesenchymal stem cels/new nerve conduit composite material can be used for peripheral nerve repair and present exact achievements.

Objective To study the change of Th1, Th2 cytokine levels in culture supernatants of PBMC in pregnancy induced hypertension (PIH). Methods 43 PIH patients, 15 normal pregnant women, and 15 healthy non-pregnant women were studied randomly. Levels of IL-2?IFN? and IL-4 in culture supernatants of PBMC were detected by ELISA. Results In culture supernatants of PBMC, IL-2 level of normal pregnant women was(140.3? 73.2 )ng/L, decreased significantly in comparation with that of healthy non-pregnant women (259.5?114.4)ng/L, P

Objective To Observe the effects of tumor necrosis factor ? (TNF ?) on cell proliferation and Intracellular free calcium concentraction ([Ca 2+ ]i) in endothelium of human umbilical vein endothelial cells (HUVEC) and investigate the pathogenesis of pregnancy induced hypertension syndrome (PIH). Methods Confluent monolayer of HUVEC was directly incubated with TNF ? at following final concentrations: 500, 1 000, 2 000 U/ml for 24 hours. The percentages of different cellcycles and [Ca 2+ ]i were measured by flow cytometry and fluorospectrophotometry. Results Incubated with TNF ?, the endothelial cells were elongated and transformed into fibroblast like cells. Border of nucleus was sharp, clarity, and cells were in regular shape. But there were abnormal granules in cytoplasma and some cells detached at the concentrotion of 2 000 U/ml of TNF ?. Stimulated by TNF ?, the percentage of cellcycles from phase G 0+G 1 to S and G 2+M decreased significantly and it was dose dependent. [Ca 2+ ]i increased significantly and dose dependent as well. Conclusion TNF ? may injure endothelium directly and inhibit its proliferation and repair through the changes of [Ca 2+ ]i level. It may play an important role in the pathogenesis of PIH.

Background:Clinical and epidemiological studies revealed that estrogen replacement therapy was associated with a significant reduction in risk of colorectal cancer in postmenopausal women.In our previous studies,estrogen increased the expression of mismatch repair (MMR)gene MLH1 in colonic cancer cells,and re-expression of MLH1 in MLH-deficient colonic cancer cells significantly increased the estrogen-induced apoptosis.Aims:To investigate the signaling pathway implicated in the MLH1-mediated apoptosis in colonic cancer cells induced by estrogen and the roles of p53 and its related genes in this apoptotic pathway.Methods:Plasmid containing wild type human MLH1 (hMLH1)full length cDNA was transfected into MLH1-deficient human colonic cancer cell line HCT116.By using HCT116 cells transfected with empty plasmid as controls,the apoptotic DNA ladder was determined by electrophoresis and the expressions of p53 and other apoptosis-related proteins were assessed by Western blotting under the condition with or without estrogen stimulation. Results:17β-estradiol (E2 )at the concentration of 10 -8 mol/L induced significant apoptosis in HCT116 cells transfected with hMLH1.In HCT116 cells transfected with hMLH1 and stimulated with E2 (group D),the protein expressions of caspase-3,caspase-9,p53,Bax and cytoplasmic cytochrome C increased significantly when compared with HCT116 cells stimulated with E2 only (group B);expressions of the abovementioned proteins were also higher in group D than in group C (transfected with hMLH1 only).Conclusions:MMR gene MLH1 is involved in estrogen-induced apoptosis of human colonic cancer cell line HCT116 by activating p53 signaling and mitochondrial apoptotic pathway.
