Objective In order to provide scientific evidence for revealing the pathophysiological changes, levels of the humoral and cellular immunity and cytokines in elderly patients with bacterial pneumonia were determined. Methods The changes of immunological markers including IgA, IgG, IgM,C3, C4,T cell subpopulation (CD3 +, CD4 +, CD8 +) and CD4 +/CD8 +, IL 2, IL 6, IL 8, TNF ? were examined for the elderly bacterial pneumonia group(BPG), the aged control group(ACG) and the young control group(YCG). Results The level of CD3 +〔(53 90?7 10)% vs (62 67?6 08)%〕, CD4 +〔(33 85?4 69)% vs (3 57?3 40)%〕, IL 2〔(4 09?0 69) ?g/L vs (6 72?0 52) ?g/L〕 and IL 8〔(0 28?0 07) ?g/L vs (0 39?0 09) ?g/L〕 in ACG were significantly lower than those in YCG. The levels of IgA, IgG, IgM, C3, CD8 +, IL 8〔(0 33?0 08) ?g/L vs (0 28?0 07) ?g/L〕, and TNF ?〔(1 25?0 23) ?g/L vs (1 10?0 20) ?g/L〕in BPG were significantly higher than those in ACG; and in BPG the levels of IgG, IgM, C3, IL 8 and TNF ? were significantly higher than those in YCG. However, the levels of CD3 +, CD4 + and the ratio CD4 +/CD8 +in BPG were markedly lower than those in YCG;the IL 2(2 730?0 612 ?g/L) was much lower than that of ACG〔(6 72?0 52) ?g/L〕 and YCG〔(4 09?0 69) ?g/L〕, respectively. Conclusions The occurrence and the progress of bacterial pneumonia in the elderly are related to the immunological functioning including the excessive humoral immunity, the super activation of complement system, the dysequilibrium of T cellular immunoloregulation network and the super excretion of inflammatory cytokines.

Objective To study the effect of salmon calcitonin and physical therapy on lumbar spinal ste- nosis.Methods Eighty cases of lumbar spinal stenosis were divided into treatment and control groups.Physical therapy alone was given to the control group,but salmon calcitonin was injected intramuscularly in addition to phys- ical therapy for the patients in the treatment group.Visual analogue scale,range of motion (ROM),pain-free walking distance,tendon reflexes and functional independence measures (FIM) were observed to assess the re- sults.Results The VAS,ROM and walking distance of the treatment group improved more than those of the con- trol group,but the groups' tendon reflexes and FIM were similar.Conclusions Salmon caleitonin can reduce the symptoms of lumbar spinal stenosis,and it has special effects in relieving pain.

Objective To establish the standard for quality control ofQingyan Granule. Methods The chief components of the preparation, Sophora Tonkinensis radix et rhizoma, Adenophorae radix, Lonicera japonica caulis, and Ophiopogonis radix were identified by TLC qualitatively. The contents of licorice glycosides and glycyrrhizic acid were determined by HPLC. The separation was performed on Thermo Syncronis C18 column (4.6 mm×250 mm, 5μm) with mobile phase consisted of acetonitrile with 0.05% phosphoric acid solution (A)-0.05% phosphoric acid solution (B), and gradient elution (0-8 min, 19%A;8-35 min, 19%→50%A). Detection wavelength was 237 nm, and flow rate was 1 mL/min.Results The spots in TLC were clear. There were spots with same color on the corresponding location of reference substance and reference herbal, negative control without interference. The linear range for licorice glycosides was 0.05-0.5μg (r=0.999 9). The average recovery was 99.97%, RSD=1.74% (n=9). The linear range for glycyrrhizic acid was 0.1-2μg (r=0.999 9). The average recovery was 99.74%, RSD=1.28% (n=9). Conclusion The method is simple, accurate, with high reproducibility, which can be used for quality control ofQingyan Granule.

Objective To investigate the expression of anti-endothelial cell antibody AECA in the emphysema rats induced by smoking and to analyze the intervention effect of methylprednisolone on it.Methods Thirty-nine rats were randomly divided into the control group,smoking rat emphysema model group (model group) and methylprednisolone intervention group (intervention group).The model group and intervention group conducted the 1-month passive smoking by smog exposure.The intervention group was intraperitoneally injected by methylprednisolone(once daily,6 d per week).After exposing to smog for 90 d,the differences of serum AECA level,IL-8,MMP-9 and TNF-α level in bronchoalveolar lavage fluid(BALF),lung MLI and mean alveolar number (MAN) were compared among groups.Results Compared with the control group and theintervention group,the level of serum AECA in the model group was significantly increased (P＜0.05);Compared with the control group and intervention group,the IL-8,TNF-α and MMP-9 levels of BALF in the model group were also increased(P＜0.05).Conclusion ACEA participates in the smoking induced emphysema formation;methylprednisolone may decrease the level of AECA and cell inflammatory factors and affects the emphysema formation.

BACKGROUND: Runx2 plays a central role in osteogenic differentiation, which is of important significance in new bone formation.OBJECTIVE: To observe the effect of Runx2 over-expression on osteogenic differentiation of human umbilical cordblood mesenchymal stem cells.METHODS: Runx2 was generated by RT-PCR and the recombinant adenovirus (pAd-Runx2) was constructed. The viraltiter was determined by air dilution method. After being transfected into human umbilical cord blood mesenchymal stemcells, the green fluorescence was observed under fluorescence microscope. Real-time fluorescent quantitative PCR andwestern blot were used to detect mRNA expression changes of osteogenesis related genes, Runx2, OCN, BMP-2, ALP,in human umbilical cord blood mesenchymal stem cells at 1, 3, 7 and 14 days after transfection.RESULTS AND CONCLUSION: The recombinant adenovirus was successfully constructed and the titer was1.7×1010 pfu/L. After infection by pAd-Runx2, human umbilical cord blood mesenchymal stem cells expressed greenfluorescence protein clearly under the fluorescence microscope. Cells in the transfected group differentiated intoosteoblast-like cells, and those in the control group stayed the same as pre-infected. The expression of Runx2, OCN,BMP-2 and ALP in the transfected group increased over time to some extent, but these changes were not detected in thecontrol group. These findings indicate that Runx2 over-expression can promote the osteogenic differentiation of humanumbilical cord blood mesenchymal stem cells.

AIM: To investigate the effects of TGF-?_1 and signal protein Smad3 on rat cardiac myocyte hypertrophy.METHODS: The total protein was analyzed by flow cytometry and the ANF mRNA expression was measured by RT-PCR to judge the hypertrophy of cultured neonatal cardiac myocytes.Smad3 mRNA expression in cardiac myocytes was measured by RT-PCR,and the protein expression of Smad3 was analyzed by Western blotting.RESULTS: TGF-?_1 significantly increased the total protein in cardiac myocytes and promoted ANF mRNA expression,compared with control group.In cultured neonatal myocytes,AS-ODN of Smad3 inhibited myocyte hypertrophy induced by TGF-?_1.Smad3 mRNA and protein expression increased at 15 min after incubated with TGF-?_1,reached the peak at 1 h,and declined at 4 h.CONCLUSION: TGF-?_1 and signal protein Smad3 may participate in the progress of rat cardiac myocyte hypertrophy.
