BACKGROUND:Percutaneous kyphoplasty with bone cement injection for repair of multi-segmental thoracolumbar vertebral osteoporotic fractures can restore the compressed vertebral height, correct deformity and reduce complications. OBJECTIVE: To explore the therapeutic effects of percutaneous kyphoplasty with bone cement in patients with multi-segmental thoracolumbar vertebral osteoporotic fractures. METHODS:Eighty patients with multi-segmental thoracolumbar vertebral osteoporotic fractures were enroled, 29 males and 51 females, aged 61-78 year, including 52 case of two-segmental vertebral fractures, 22 cases of three-segmental vertebral fractures, 6 cases of four-segmental vertebral fractures. Al the patients were divided into experimental group and control group randomly. Patients in the control group were given active basic treatment and anti-osteoporosis treatment and stayed in bed. Patients in the experimental group were given percutaneous kyphoplasty with bone cement injection on the above basis. Al the patients were folowed-up 12 months after treatment. Then the Oswesty dysfunction index, Barthel index, visual analog scale score, and theanterior vertebral height and midline height, Cobb angle were compared between the two groups. RESULTS AND CONCLUSION: In the experimental group, the Oswesty dysfunction index, Barthel index, visual analog scale score, and the anterior vertebral height and midline height, Cobb angle were al significantly improved at 3 days, 3 months and 12 months after treatment than before (P < 0.05). In the control group, the Oswesty dysfunction index, Barthel index and visual analog scale score were improved significantly at 3 and 12 months after treatment (P < 0.05), while the anterior vertebral height and midline height were improve dramaticaly at 12 months after treatment (P < 0.05). Compared with the control group, the experimental group showed better the Oswesty dysfunction index and Cobb angle than the control group at 12 months after treatment (P < 0.05), but there were no difference in the other indicators between the two groups. No adverse reactions associated with bone cement material occurred in the experimental group. Taken together, the percutaneous kyphoplasty with bone cement injection can rapidly relieve pain in patients with multi-segmental thoracolumbar vertebral osteoporotic fractures, which can correct kyphosis and improve patient's quality of life.

BACKGROUND:Bone marrow mesenchymal stem cel transplantation is a hot spot in the treatment of ischemic cerebrovascular diseases, and CT brain perfusion scan is mostly used to observe the improvement in the blood flow in the ischemic region. However, X-ray irradiation during CT brain perfusion may affect the viability of transplanted bone marrow mesenchymal stem cel s, and then influence the therapeutic efficacy. OBJECTIVE:To investigate the effect of CT brain perfusion dose on the viability of bone marrow mesenchymal stem cel s. METHODS:Passage 5 bone marrow mesenchymal stem cel s from Sprague-Dawley rats were selected and randomized into three groups, with 6 tubes in each group. One of the six tubes in each group was randomly selected with no irradiation, and the remaining five tubes in each group were subjected to CT brain perfusion scans 1-5 times, respectively. After scanning, the cel number was counted after 10-day continuous culture and cel growth curve of each tube was drawn. Cel cycle was detected by flow cytometry, and cel viability was measured by MTT method. RESULTS AND CONCLUSION:After 10 days of continuous counting, the number of cel s per tube showed no difference (P>0.05), and cel growth curves were basical y coincided. Moreover, there was no significant difference in the cel cycle and cel viability (P>0.05). Experimental findings show that the CT brain perfusion scan has no effect on the viability of bone marrow mesenchymal stem cel s.

Recently,commercialized infant body plethysmography has been widely used in clinic and re-search,especially with the publication of recommendation for this equipment and methodology. As the most valu-able equipment in measuring airway resistance and lung volume,infant body plethysmography can show series of valuable data on lung function,which is important in assessing pulmonary growth and development,evaluating respiratory mechanics and helping diagnose disease. However,the application of infant body plethysmography in clinic and physiology measurements is still limited by the effectivity of this equipment and appropriate reference values. This review is to introduce body plethysmography in infants,describe frequently-used data of lung func-tion,and discuss its potential clinical significance and availability of reference values.

Objective:To examine whether the existence of the donor-and-recipient-derived DNA chimerism in recipient’s plasma can be a predictive marker for the status of transplanted organ.Methods:One hundred and twenty-six female patients who had been transplanted with male kidney were enrolled in the present study.In these female recipients,the SRY1,DYZ11st and DYZ12nd genes on the Y chromosome from the plasma were prospectively examined using reverse transcription polymerase chain reaction (RT-PCR).Results:SRY1,DYZ11st and DYZ12nd sequences were detected in the cell-free blood (plasma) of 97 (77%) of 126 female patients with male kidney.The average time-span when the transplanted kidneys functioned was 8.7 years and 5.4 years among microchimerism-positive and microchimerism-negative recipients,respectively.The frequency of the patients who had acute rejection after renal transplantation was approximately 10% and 28%in microchimerism-positive and microchimerism-negative recipients,respectively.Serum creatinine levels in microchimerism-positive patients were significantly lower than those in microchimerism-negative patients.Conclusion:These results suggest that plasma DNA microchimerism is present in certain patients following renal transplantation and measurement of plasma DNA microchimerism using quantitative RT-PCR might be a useful predictor for the acceptance of transplanted kidneys.
