Objective To characterize the language development and articulation in children with different types of cerebral palsy. Methods The data from 76 children with cerebral palsy who underwent standardized tests of speech and language were analyzed. The incidence and abnormal pattern were compared between groups. ResultsLanguage delay and/or dysarthria were noted in 73.1% of these subjects. Children with diplegia developed similar levels both in comprehension and verbal expression, whereas those with tetraplegia and athetoid developed poorer verbal expression. The incidence of language delay in children with diplegia, tetraplegia and athetoid were 45.95%, 90% and 64.7%, respectively. Dysarthria was found in all the children with tetraplegia, athetoid and ataxia, but only 48.65% of those with diplegia. Conclusion Language disorders were common in children with cerebral palsy, especially those with athetoid and tetraplegia.

Objective: To explore the influence factors of the degenerate oligonucleotide primered PCR(DOP-PCR). Methods: Genome DNA template from the mouse single oocyte or liver tissue were used to perform DOP-PCR. DOP-PCR was carried out with templates of different origin, different gradient dilution, with or without low melting point gel purified to wipe off the small fragment that might interfere with the following analysis, and then PCR of gene FTCD and CBS were carried out to evaluate the influence of these factors on the amplification efficiency and specificity. Results: Compared with genome DNA template from mouse liver, the template from single oocyte had the same efficiency and specificity but a minor yield and different gradient dilution of DNA template had no effect on the efficiency and specificity. Furthermore, there was a higher specificity in the low melting point gel-purified DOP-PCR product than in untreated ones. Conclusion: We have got a satisfactory result and increased specificity from DOP-PCR product purified with the low melting point gel. Single oocyte of mice could be used for further investigation of special genes detection by DOP-PCR and of an optimization in the yield of the products.

ObjectiveTo study the rehabilitation effect of physical therapy on patients with above knee amputation. Methods50 patients with above knee amputation were evaluated with FIM scale before and after physical therapy. ResultsThere was a significant difference before and after physical therapy(P<0.05). Conclusions Physical therapy is effective on patients with above knee amputation.

Objective A resistin binding peptide (RBP) was selected by phage display in our previous work. Studies had shown that RBP could antagonize the role of resistin on the lipid metabolism and endocrine function of adipose tissue, but whether RBP affects the insulin secretion of pancreatic cells is still unknown. The aim of this study is to assess the effect of RBP on basal insulin secretion in RINm5F insulinoma cells. Methods The cell viability was measured by 3-[4,5-dimethyhhiazol-2-yl]-2,5-diphenyltetra-zolium bromide (MTT) cytotoxicity assay. The supernatants were assayed for insulin content by enzyme linked immunosorbent assay (ELISA). Reverse transcriptase-PCR assay and Western blotting were used to determine the expression of glucose transporter 2 (GLUT2) involved in insulin secretion. Cytosolic Ca2+, the trigger of insulin exocytosis, was analyzed with the fluorescent probe FURA-3/AM. Results RBP did no effect on the cell viability with a concentration of 10-8-10-12mol/L of 2 hours intervention. But it stimulated basal insulin secretion of RINm5F cells, accompanied by up-regulated increased expression of GLUT2 and elevated concentration of cytosolic Ca2+. Conclusion RBP could stimulate basal insulin secretion without affecting the cell viability.

OBJECTIVEThe aim of this study is to investigate the occurrence and mechanism of Cheyne-Stokes breathing pattern in patients with heart failure.

METHODSFifty-six patients who performed polusomnography sleep testing at National Center of Cardiovascular Diseases Fuwai Hospital from March to May in 2015. We divided them into chronic heart failure (CHF) group and non-CHF group.

RESULTSThe occurrences of sleep apnea in two groups were high. In CHF group (n = 11) , there were 10 patients with apnea hypopnea index (AHI) > 5; and their AHI was 23.93 ±14.63. In non-CHF group (n = 45), there were 33 patients whose AHI > 5; and their AHI was 16.20 ± 18.76. The ratio of center sleep apnea to all gross sleep apnea ratio in CHF group was higher than that in non-CHF group (80.21% ± 30.55% vs 27.16% ± 35.71%, P < 0.01 ).

CONCLUSIONBased upon the new theory of holistic integrative physiology and medicine, we explain the mechanism of circulatory dysfunction induce the oscillation breathing in patients with CHF. The sleep apnea and C-S respiration in CHF should be called circulatory sleep apnea, rather than central sleep apnea.

OBJECTIVETo observe the effect of natural borneol on the permeability of blood tumor barrier (BTB) model and the expression and activation of mitogen-activated protein kinase (MAPKs) signal transduction pathway related protein kinase in vitro.

METHODSC6 rat glioma cells and human umbilical vein endothelial cells (HUVECs) were co-cultured to establish BTB model. Then 4 groups were set up, the blank control group, low, middle, and high dose borneol groups (25, 50, 100 µg/mL), 3 samples collected at 7 time points (0, 10, 30, 60, 120, 180, 240 min, respectively). Blank culture medium was exchanged in the blank control group while medication. Different doses of natural borneol were administered to the 3 borneol groups. Cells were collected at different time points. BTB permeability was determined using horseradish peroxidase (HRP). Expression levels of extracellular signal regulated protein kinase (ERK), phosphorylation extracellular signal regulated protein kinase (P-ERK), P38MAPK, phosphor-P38MAPK, c-Jun N-terminal kinase (JNK), and phosphorylation c-Jun N-terminal kinase (P-JNK) were detected using Western blot.

RESULTSCompared with the same group at min 0, the permeation rate obviously increased (P < 0.01) in the 3 borneol groups at the rest time points. P-ERK expression was elevated first, reached the peak at 30 min, and gradually recovered to the initial level (P > 0.05). Compared with the blank control group, HRP permeation rate increased from 10 min to 240 min (P < 0.01), and expression of P-ERK protein increased at 30 min and 60 min (P < 0.05) in the low dose borneol group; expression of P-JNK protein decreased in the 3 borneol groups at 180 min and 240 min (P < 0.05). Compared with the low dose borneol group, expression of P-ERK protein increased from 10 min to 180 min (P < 0.05), HRP permeation rate increased from 30 min to 180 min (P < 0.05), expression of P-JNK protein decreased at 180 and 240 min (P < 0.05) in the middle dose borneol group. Compared with the middle dose borneol group, HRP permeation rate increased from 10 min to 180 min (P < 0.05), expression of P-ERK protein increased from 10 min to 180 min (P < 0.05), expression of P-JNK protein increased at 180 min and decreased at 240 min (both P < 0.05) in the high dose borneol group.

CONCLUSIONNatural borneol arrived at the effect of regulating reversible BTB patency possibly through activating phosphorylation of ERK in MAPKs signal transduction pathway, and further reversibly down-regulating expression of associated proteins.
