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.

OBJECTIVETo compare efficacy of unilateral external fixators and locking compression plates in treating type C fractures of the distal radius.

METHODSFrom January 2009 to June 2010, 76 patients with distal radius fracture were treated with LCP and external fixators, 54 patients were followed up. Among them, 29 cases were male and 25 cases were female with an average age of 45.31 (ranged, 24 to 68) years old. There were 29 patients in LCP group. According to AO classification, 8 cases were type C1, 7 cases were type C2 and 14 cases were type C3. There were 25 cases in external fixators group. According to AO classification, 6 cases were type C1, 8 cases were type C2 and 11 cases were type C3. Radial height, volar tilt and radial inclination were compared, advanced Gartland-Werley scoring were used to assessed wrist joint function after 6 and 12 months' following up.

RESULTSTwo cases were suffered from nail infection in external fixators group. Fifty-four patients were followed up from 12 to 24 months with an average of 21.3 months. Radial height was (9.60 +/- 0.72) mm, volar tilt was (9.55 +/- 0.80) degrees and radial inclination was (21.40 +/- 0.78) degrees in LCP group,while those were (9.40 +/- 0.70) mm, (9.47 +/- 0.71) degrees and (21.20 +/- 0.73) degrees in external fixtors group, and with no statistical significance (P>0.05). Advanced Gartland-Werley score after 6 months' following up was 3.31 +/- 1.17 in LCP group, 5.56 +/- 1.58 in external fixtors group, and with significant difference (t=-5.99,P<0.05); after 12 months' following up, advanced Gartland-Werley score was respectively 2.66 +/- 1.01 and 3.08 +/- 1.00, but with no statistical meaning (t=-1.55, P>0.05).

CONCLUSIONLCP and external fixtors can receive good curative effects in treating type C distal radius fracture, and LCP can obtain obviously short-term efficacy, while there is no significant difference between two groups in long-term results. For serious distal radius comminuted fracture which unable to plate internal fixation, external fixators is a better choice.

Objective To explore the clinical significance of the brain natriuretic peptide(BNP) in evaluating the cardiotoxicity caused by daunorubicin(DNR) through studying the changes of the plasma BNP levels in children with acute leukemia who accepted the chemotherapy with DNR.Methods Thirty-one children with acute lymphoblastic leukemia(ALL) admitted in the year of 2002-2004 underwent the chemotherapy in DVLP project.The plasma level of BNP was measured by enzyme linked immunosorbent assay(ELISA) and the left ventricular end diastolic diameter(LVEDD) by color Doppler respectively before and after the administration of DNR.Simultaneously,electrocardiography(ECG) and cardiac muscle enzymes(LDH1,CK-MB) were measured as routine.Results The plasma level of BNP increased from(3.97?2.41) ng/L to(18.25?7.63) ng/L(P

Objective To explore the significance of detecting miR-145 hypermethylation in non-small cell lung cancer (NSCLC). Methods Seventy-five NSCLC tissues and adjacent tissues was collected from May 2012 to January 2015. The methylation status of miR-145 promoter was tested by bisulfite sequencing PCR (BSP) and the expression of miR-145 evaluated by ISH. The correlation between miR-145 methylation and clinical parameters , and the relationship between miR-145 methylation and expression were statistically analyzed. Results The hypermethy-lation ratio of miR-145 in NSCLC tissues was higher than that in the adjacent tissues. Hypermethylation of miR-145 was correlated with NSCLC differentiation stage, but not with gender and age. In NSCLC, miR-145 hypermethyla-tion was negatively related with its expression. Conclusion MiR-145 hypermethylation is closely related with dif-ferentiation stage in NSCLC tissues. MiR-145 hypermethylation may be a potential biomarker for estimating NSCLC differentiation stage.

Objective To investigate the expression and effect of miR-22-3p in non-small cell lung cancer (NSCLC). Methods The miR-22-3p expression level in seventy-six NSCLC tissues and para-cancer tissues was detected by qRT-PCR. The relationship between the expression of miR-22-3p and gender,age,tumor size,histolo-gy grade,pathological type and lymph node metastasis was analyzed. The function of miR-22-3p on the prolifera-tion of NSCLC cells was tested by growth curve assay. Target genes of miR-22-3p were predicted by online software Targetscan. Luciferase reporter assay and qRT-PCR was used to certificate the prediction. Results The expression of miR-22-3p was increased in NSCLC tissues than the para-cancer tissues and was correlated to lymph node metas-tasis. Overexpression of miR-22-3p could suppress the proliferation of A549 cells. Astrocyte-Elevated Gene-1(AEG-1) was predicted to be a target of miR-22-3p. MiR-22-3p was revealed to bind to AEG-13′UTR by luciferase report-er assay. Overexpression of miR-22-3p could inhibit the expression of AEG-1 in A549 cells. Suppression of miR-22-3p could increase AEG-1 expression. Conclusion MiR-22-3p could inhibit the proliferation of NSCLC by tar-geting AEG-1.

Objective To summarize the clinical features and technical key points on brain death during decision-made process in children with suspected brain death.Methods Twenty-four coma children with Glasgow coma scale score 3 and no spontaneous respiration were collected from May 2015 to February 2017 in Beijing Children's Hospital,Capital Medical University to make the brain death determination.All children received at least one confirmatory test.According to the Chinese standards for determining brain death (pediatric),all patients were divided into brain death group and non-compliance group.The clinical features were analyzed.The sensitivity,specificity,false positive rate and false negative rate of electroencephalogram (EEG),short latency somatosensory evoked potential (SLSEP) and transcranial Doppler sonography (TCD) were calculated.Results Among these 24 cases,there were 16 males and 8 females,aged 5.6 (2.0,8.8) years old.Ten cases met the criteria of brain death.Twelve (50％,12/24 cases) cases received autonomic breathing test.A total of 25 tests were conducted,of which 21 were successful.The completion rates of EEG,TCD and SLSEP were 100.0％ (24/24 cases),83.3 ％ (20/24 cases) and 54.2％ (13/24 cases),respectively.EEG had the highest sensitivity (100％) and specificity (79％).SLSEP had good sensitivity (100％),but the specificity was only 40％.The combination of EEG with SLSEP had the highest specificity and sensitivity,both of which were 100％,and the false positive rate and false negative rate were 0.Conclusions The key to determine brain death successfully is to make adequate preparations,to receive formal training and to apply standard operation.In the determination of brain death in children,EEG has a good sensitivity and specificity in single confirmation test,which is the priority item.The combination of EEG with SLSEP is the most advantageous.

Objective To investigate the protective effect and therapeutic window of DGMI on ischemic stroke in rats,and to explore the related mechanism.Method The rats were subjected to middle cerebral artery occlusion (MCAO) for 90 min followed by 72 h of reperfusion.DGMI (i.p.,1.25,2.5,5.0,and 10.0 mg/kg,Bid) was administered at 1 h after the onset of ischemia.Neurological score was evaluated after 24 and 72 h of reperfusion rcspectively.In fact volume,cerebral water content,oxidative stress markers,and IL-1β were evaluated after 72 h of reperfusion.The rats were treated with DGMI 5.0 mg/kg 0.5 h before reperfusion or 1 h,2 h,3 h,and 6 h after reperfusion to determined therapeutic window.Result Treatment with DGMI (2.5,5.0 mg/kg) significantly ameliorated neurological deficit,infarct volume and cerebral water content after cerebral ischemia reperfusion.DGMI also reduced the content of malonaldehyde (MDA),IL-1β,down-regulated the activities of creatine kinase (CK),lacticdehydrogenase (LDH),and up-regulated the activities of superoxide dISmutase (SOD).Treatment with DGMI 5.0 mg/kg exhibited protective effects when administered at all time points except for 6 h after reperfusion.Conclusion DGMI plays a certain protective role in ischemic stroke of rats,and the effect may be related to the improvement on the antioxidant capacity of brain tissue and the inhibition of overproduction of inflammatory cytokine.Moreover,the therapeutic window of DGMI isless than 6 h after reperfusion.

Objective To investigate the relationship between plasma concentration of B type natri uretic peptide (BNP) and the severity and prognosis of patients with acute spontaneous intracerebral hemorrhage (ICH).Methods Review of 86 cases of patients with spontaneous intracerebral hemorrhage analysis in our hospital Department of Emergency/Surgical Intensive Care Unit (ED/S1CU) were admitted within 6 hours of admission to collect blood samples,head CT,biochemical index,Glasgow Coma Scale (GCS) score and other clinical data,and detected within 6 hours after admission,the admission of third days and 7 days of plasma BNP concentration.The blood volume of cerebral hemorrhage was computed.The GCS was used to evaluate nerve function after admission.The survival of 28 days was observed.Results The concentration of BNP detected at 3 time points increased with the increase of the amount of bleeding in patients with acute cerebral hemorrhage and increased with the decrease of GCS score at admission (P ＜0.01).The BNP concentration was mild higher in the small amount of bleeding group than that of the control group (P =0.094),while that of the other two groups were significantly higher (P ＜ 0.01).Concentration of BNP detected within 6 hours of admission was positively correlated with cerebral hemorrhage (r =0.551).The a mount of BNP in the 6 hours after admission of the GCS ＞ 8 group was significantly higher than those of the control group (P ＜ 0.05),and the GCS ≤ 8 group was significantly higher than that of the control group and GCS ＞ 8 group (P ＜ 0.01).The BNP concentration was negatively correlated with GCS score at admission (r =-0.532).The 28-day mortality was predicted by BNP ＞ 168 pg/ml for 6 hours,AUC was 0.814,the sensitivity was 75.0％ and the specificity was 81.4％.Conclusions The concentration of BNP in patients with acute spontaneous intracerebral hemorrhage increased with the increase amount of bleeding and the decrease of GCS score at admission.The concentration of BNP in the 6 hours after admission was correlated with the severity and the prognosis of the disease,which can be used as the important reference indicators for evaluating severity and prognostic prediction.
