Objective To investigate the risk of myocardial damage induced by obstructive sleep apneahypopnea syndrome (OSAHS) in children. Methods Twenty-three children who were in-hospital patients and diagnosed as adenoidal hypertrophy or palatine tonsil hypertrophy enrolled in the study as cases,among whom 15cases were affected by OSAHS (OSAHS group) ,and 8 cases were not affected by OSAHS( no-OSAHS group).Twenty-seven healthy children from health physical examination were enrolled as controls (control group).Chemiluminescence was used to detect the value of Troponin Ⅰ (TnⅠ) in all children, and the values of the three groups were compared. Results In the OSAHS group, TnⅠ was (0. 022 ± 0. 009) μg/L;in the non-OSAHS group, TnⅠ was (0.035 ± 0.012) μg/L;in the control group,TnⅠ was (0.017 ± 0.015) μg/L. There were significant difference among the three groups ( F = 8. 369, P = 0. 001 ). Furthermore, compared with the control group,TnI in the OSAHS was significantly higher( P ＜ 0. 001 ). Conclusion Children with adenoid or tonsil hypertrophy associated with OSAHS in children were found to have myocardial damage compared to healthy children, whereas similar on myocardial damage to children with adenoid and tonsil hypertrophy but not OSAHS.

BACKGROUND: The low survival rate of neuron cells is one of the main mechanisms of stem cell allograft, which might lead to the failure of allograft. Nuclear factor-KB (NF-kB) is one of main transcription factors for cell signaling transduction and participates in call proliferation and differentiation.OBJECTIVE: To study the differentiation of muscle-derived stem cells (MDSCs) into neuron-like cells induced by ciliary neurotrophic factor (CNTF) and Compound Salvia Miltiorrhiza Injection in vitro, and the expression of NF- kB.DESIGN, TIME AND SETTING: The experiment at cell molecular level was performed at the Oral Science Laboratory of the Second Affiliated Hospital of Liaoning Medical College from March to May 2008.MATERIALS: A total of 10 Sprague Dawley neonatal rats aged 7 days were supplied by Experimental Animal Center, Liaoning Medical University. CNTF (Sigma, USA) and Compound Salvia Miltiorrhiza Injection (Chiatai Qingchunbao Pharmacantical Co.,Ltd., China) were used in this study.METHODS: Rat MDSCs were harvested in vitro, pudfied by differential adherence and enzyme digestion, and incubated in 6-well plate. Samples in the induction group were incubated in DMEM containing CNTF for 24 hours. The medium was changed.Subsequently, samples were dnsed three times, and then incubated in serum-free DMEM supplemented with Compound Salvia Miltiorrhiza Injection for 5 hours. Samples in the control group were treated with serum-free DMEM.MAIN OUTCOME MEASURES: Neurofilament protein and NF-KB inhibitor protein expression were detected using reverse transcription-polymerase chain reaction (RT-PCR) and Westem blotting.RESULTS: No neurofilament protein expression was found in MDSCs before induction, and neurofilament protein-positive MDSCs were detected following induction. Results of gel electrophoresis and Westam blot showed that no significant differences in NF-kB inhibitor protein expression were determined in the control group, and NF-kB inhibitor protein expression was significantly decreased in the induction group after induction.CONCLUSION: CNTF and Compound Salvia Miltiorrhiza Injection could inhibit the activation of NF-kB and induce the differentiation of MDSCs into neuron-like cells.Zeng XY, Wang W, Sun L, Zhang L, Zeng LD.Differentiation of muscle-derived stem cells into neuron-like cells induced by ciliary neurotrophic factor and Compound Salvia Miltiorrhiza Injection in vitro.Zhongguo Zuzhi Gongcheng Yanjiu yu Linchuang Kangfu.2009;13(27): 5336-5340.

Objective To investigate the preventive effects of Buyang Huanwu Decoction (BYHWD) and its recipe composition (BYJJF) in focal ischemic brain injury condition in vivo/in vitro. Methods In vivo studies, SD rats were divided into sham-operation group, MCAO group, BYHWD group and BYJJF group based on rat weight, 10 rats in each group. The body weight, infarct area and brain water contents were determined. In vitro studies, H2O2 was used to damage PC12 cells, and the vitro oxidative stress cell model was established. PC12 cells were divided into normal group, blank control group, BYHWD and BYJJF groups with different concentrations (0.1, 0.2, 0.5, 1.0, 2.0, 3.5 mg/mL). MTT method was employed to determine the protective effects of BYHWD and BYJJF on model cells.Results Vivo studies showed that after 7 days of treatment with BYHWD and BYJJF, those determinated quotas were all significantly improved compared with MCAO model rats (P<0.05), and there were no differences between BYHWD and BYJJF (P>0.05).Vtiro studies showed that the protective effects of BYHWD and BYJJF took place 2 hours later, and it was obvious in oxidative stress injury caused by H2O2, with statistical differences with model group (P<0.05). BYHWD and BYJJF could increase cell viability, and there was no difference between the groups with same concentration (P>0.05).Conclusion The research confirmed that BYJJF plays a significant role in improving the cerebral ischemia injury, which is the same performance as BYHWD, and BYJJF can save TCM resources under the precondition of TCM efficacy.
