ABSTRACT
Objective To survey the survival status, functional status, marital status and the present situation of the survival patients with spinal cord injury 40 years after Tangshan earthquake. Methods From February to May, 2016, a total of 216 patients with spinal cord injury were surveyed with questionnaire, in which 139 cases lived centralized and 77 cases lived scattered. The questionnaire was self-designed and included eleven items and 51 questions, which related to ability of daily life, marital status, employment status and socioeconomic status and so on. Results A total of 960 (25.15%) patients with spinal cord injury survived 40 years after Tangshan earthquake. In 216 surveyed pa-tients, the employment rate was 9.3%, the married rate was 53.2%, and 44.9%earned less than 500 yuan every month. The incidence was 25.9%for pressure score, 50.50%for neuralgia (severe pain accounted for 23.51%), and 19.40%for urinary tract stones. 56%of patients could take their own basic self-care. Conclusion There were many problems such as high complication rate, low employment rate and poor economic condition in the spinal cord injury group 40 years after Tangshan earthquake.
ABSTRACT
(DBI) in rats by observation on the changes of Homer 1a expression and apoptotic nerve cells . Methods Spraque-Dawlley(SD) rats were randomly ( random number ) divided into control group and severe DBI group .DBI rat model was established according to the de-scription of Marmarou′s diffused brain injury .No injury was done on control group .The changes of neuron pathology were observed by light microscopy and electron microscope .The expression of Homer1a was observed by immunohistochemistry and western blot .The quan-tity of apoptotic cells was measured by terminal deoxynucleotidyl transfernase medicated nick end labeling ( TUNEL) method. Results The death rate of rats in severe DBI group was 49.3%.Compared with the control group , the ultrastructures in hippocampal neurons in-cluding organelle , axonal and capillary were damaged seriously after injury , the survival rate of nerve cells decreased significantly at 1 h after injury ([99.4 ±0.6]%vs [94.4 ±5.6]%, P<0.05), and peaked at 72 h ([99.2 ±0.8]%vs [54.7 ±33.8]%, P<0 .05) in DBI group.The expression of Homer1a protein increased significantly at 1 h after injury(0 .136 ±0.024 )and peaked at6 h(0.178 ± 0.028) and maintained to 24 h (0.176 ±0.027), while decreased at 48 h (0.145 ±0.02)and 72 h (0.117 ±0.012) in DBI group;the expression of Homer 1a was obviously higher at each time point in DBI group than that in control group (P <0.05).The apoptoticindex of TUNEL positive cells increased at 6 h and demonstrated significant difference at 72h in comparison to control group ([41.78 ±3 .96]%vs [1.92 ±0.22]%, P<0.05).The correlation analysis indicated that Homer1a expression from 1~24 h and 24 h~72 h was related to the survival rate of nerve cells ( r=-0.726, P<0.05; r=0.842, P<0.05) and the quantity of TUNE positive cells(r=0.738, P<0.0;5 r=-0.898, P<0.05). Conclusion The dynamic expression of Homer1a in hippocampus after severe DBI can reflect nerve cell loss.
ABSTRACT
MicroRNAs (miRNAs) regulate the proliferation and metastasis of cancer cells. Here, we showed that miR-152 was downregulated in non-small-cell lung cancer (NSCLC) tissues and cell lines. Overexpression of miR-152 suppressed cell proliferation and colony formation and also limited migration and invasion. Fibroblast growth factor 2 (FGF2) was confirmed as a direct target of miR-152. FGF2 knockdown suppressed cell proliferation, colony formation, migration and invasion, whereas FGF2 overexpression partially reversed the suppressive effect of miR-152. Furthermore, the presence of miR-152 was inversely correlated with FGF2 in NSCLC tissues. Overall, this study demonstrated that miR-152 suppressed the proliferation and invasion of NSCLC cells by downregulating FGF2. These findings provide novel insights with potential therapeutic applications for the treatment of NSCLC.

AIM: To study the pharmacokinetic characteristics of domestic ofloxacin tablet. METHODS: A method of deter- mination of drug concentration in urine by UV-spectrophotometry was established. RESULTS: K = 0. 1 278/h; T1, 2 = 5. 96h, Xu0-24 = 165. 84mg; (Q) = 82. 84%. CONCLUSION: This method is simple and rapid, it is suitable for pharmacokinetics study and clinical monitoring.
