Objective To investigate the intelligence level and characters in children with cerebral palsy of 4~6 years old, and the factors related with their intelligence. Methods 215 cerebral palsy children of 4~6 years old were assessed with Wechsler Intelligence Scale for children,Gross Motor Function Classification System (GMFCS). Results 210 children finished their intelligence test, and 113 presented mental retardation. The intelligence level was higher in the children with spastic diaplegia, hemiplegia and dyskinetic type than those with quadriplegia and ataxia type. The difference was significant between VIQ and PIQ in the spastic diplegia (P<0.05). The mental retardation was more frequent in the children with GMFCS Ⅳ~Ⅴ, or with epilepsy or microcephaly than those with GMFCS Ⅰ~Ⅲ or without the complications (P<0.05). Conclusion The incidence of mental retardation in children with cerebral palsy was related with the neurotypes, motor function and complications.

To evaluate the prognostic value of glycated haemoglobin (HbA1c) in patients with acute myocardial infarction (AMI). Methods: A total of 1952 AMI patients were retrospectively studied. Based on medical history and HbA1c level, the patients were divided into 4 groups: Diabetes mellitus (DM) group, the patients with known DM or taking hypoglycemic drugs, n=492, Newly diagnosed DM group, MD was diagnosed during hospital stay and HbA1c≥6.5%, n=128, Pre-DM group, HbA1c 5.7%-6.4%, n=783 and Non-DM group, HbA1c<5.7%, n=549. The patients were followed-up for 25.6 months, prognostic differences during hospital stay and follow-up period were assessed by single- and multi-factor analysis. Results: The in-hospital mortality in DM group, Newly diagnosed DM group, Pre-DM group and Non-DM group were 4.88%, 3.91%, 3.96% and 2.91% respectively, P=0.435. As HbA1c level increasing, the incidences of all-cause mortality, non-fatal MI and re-hospitalization were elevating, while the differences among groups were similar. The incidences of major adverse cardiovascular events (MACE) in above 4 groups were 39.84%, 35.94%, 33.97% and 27.87% respectively, P=0.001. Compared with Non-DM group, MACE incidences in the other 3 groups were as OR=1.33, 95% CI 1.05-1.69, OR=1.45, 95% CI 0.97-2.18 and OR=1.71, 95% CI 1.32-2.22 respectively, Ptrend<0.001; with adjusted baseline parameters, Ptrend=0.008. Conclusion: In our research, MACE incidence was increasing upon HbA1c level elevating in AMI patients and it was not related to in-hospital death. HbA1c level should be screened in AMI patients, lifestyle and drug intervention could be used as necessity.

In this paper, the lethal effect on Rhizopus, Aspergillus niger, Penicillium by ozone was studied. The mortality rate against the time of the treatment of ozone and the variation of ozone concentration was measured. The changes of cell form were also observed. The Experiment results indicate that fungi could be destroyed completely by ozone and the mortality rate obviously increase with the prolonging of treatment time. When ozone was absorbed by KI,the mortality rate declines.

Objective:To explore diagnostic value of nocturnal ST-T changes in 24h dynamic electrocardiogram (DCG)for coronary heart disease (CHD)and its clinical significance.Methods:A total of 103 cases,who showed ST-T changes in 24h DCG,received selective coronary angiography (CAG).Among them,the 56 patients with in-termittent nighttime significant ST-T changes were regarded as research group,while the other 47 patients with per-sistent ST-T changes were treated as control group.CAG results were compared and analyzed between two groups. Results:Compared with control group,there were significant rise in CAG positive rate (31.9% vs.67.9%),inci-dence rates of dyspnea and chest pain (27.7% vs.66.1%),hypertension (48.9% vs.71.4%),hyperlipidemia (31.9% vs.42.9%)and diabetes mellitus (17.0% vs.46.4%),percentages of lesions in left anterior descending artery (LAD,21.3% vs.57.1%),left circumflex coronary artery (LCX,14.8% vs.37.5%)and right coronary artery (RCA,12.8% vs.35.7%)in research group,P <0.05 or <0.01. Conclusion:Nocturnal ST-T signifieantly changes in 24h DCG,it possesses more diagnostic value for CHD,which can be regarded as a more sensitive index diagnosing myocardial ischemia.

Objective To investigate the effects of perioperative high loading dose of Atorvastatin treatment on lipoprotein associated phospholipase A2 (Lp-PLA2) and heart function in patients with acute ST-segment elevation myocardial infarction and type 2 diabetes who underwent emergency percutaneous coronary intervention (PCI).Methods Totally 83 cases with acute ST segment elevation myocardial infarction and type 2 diabetes who underwent emergency PCI from September 2012 and August 2014 were randomly divided into two groups.In control group (n=42)patients took Atorvastatin 20 mg daily before and after emergency PCI,and in intensive group (n=41) patients took atorvastatin 40 mg daily before and after emergency PCI.Each group was given the same basic treatment according to the guideline.Blood samples were obtained from all the patients before PCI and at 3,7 days after PCI,and levels of Lp-PLA2 and brain natriuretic peptide (BNP)were detected.And the left ventricular end diastolic diameter (LVEDD) and left ventricular ejection fraction (LVEF) were measured at 1 day and 1 month after PCI.Results The levels of Lp-PLA2 and BNP at 3 days after PCI were obviously increased in the two groups versus baseline [(297.8± 53.4) mg/L vs.(194.7±39.1) mg/L,(270.3±47.0) mag/L vs.(205.6±27.5) mg/L,both P＜0.05],and decreased in intensive versus control group [(270.3±47.0) mg/L vs.(297.8±53.4)mg/L and (353.8±76.3) mg/L vs.(375.4±57.0) mg/L,P＜0.05].And levels of Lp-PLA2 and BNP at 7 days after PCI were improved more in intensive than in control group [(227.2±33.3)mg/L vs.(249.3±42.3) mg/L,(206.0±48.2)mg/L vs.(267.6±50.8) mg/L,P＜0.05].There were no significant differences in LVEDD and LVEF between the two groups 1 day after PCI.Meanwhile,the LVEDD was decreased and the LVEF was increased in the two groups 1 month after PCI as compared with 1 day after PCI (both P＜0.05).Conclusions Perioperative high loading dose of Atorvastatin treatment may stabilize the plaques and improve heart function in acute stage in patients with acute ST-segment elevated myocardial infarction and type 2 diabetes after emergency PCI.

Objective To evaluate the clinical application of enteral nutrition by nasojejunal tube insertion and by percutaneous endoscopic gastrostomy (PEG) in elderly patients.Methods A total of 65 elderly patients with dysphagia recruited at our department from January 2010 to November 2014 were divided into the nasojejunal tube feeding group (35 cases) and the PEG feeding group (30 cases).Differences between these two groups in nutritional indexes,immunological indexes,complications and mortality were analyzed retrospectively.Results Serum total protein,albumin and prealbumin and upper arm circumferences all increased after treatment with nasojejunal tube feeding or percutaneous endoscopic gastrostomy (P＞0.05).There was overall improvement in nutritional status,as assessed by Nutritional Risk Screening 2002 (NRS2002).Specifically,the before/one month-after-treatment ratio of scores was 3.72±0.91/1.90±0.61 (t=7.24,P＜0.01) for the nasojejunal tube feeding group and 3.52±1.23/2.02±0.53 (t=4.17,P＜0.01) for the PEG feeding group.Compared with NRS2002 scores at one month post-operation,further improvement was achieved at 3 months postoperation both for the nasojejunal tube feeding group (1.89±0.65,t=5.21,P＜0.01) and for the PEG feeding group (1.91±0.62,t=4.40,P＜0.01).There was no difference in the indexes of nutrition,immune status or mortality between the two groups (P＞0.05).Although improvement in CD3+,CD4+,CD8+,CD4+/CD8+,IgA,IgG,and IgM was seen in both groups after operation,the differences did not reach statistical significance (P＞0.05).The incidence of aspiration pneumonia was notably lower (P＜0.05) while the incidence of diarrhea was much higher (P＜0.05) in the nasojejunal tube feeding group than in the PEG feeding group at one month and three months.The two groups had similar causes of death and mortality rates.Conclusion Both nasojejunal tube and PEG feeding can improve the nutritional status of elderly patients with dysphagia.However,the choice for the route of nutrition should be individualized.

[ ABSTRACT] AIM:To investigate the effect of artemisinin on lipopolysaccharide ( LPS)-induced intestinal epi-thelial barrier damage in IEC-6 cells and its molecular mechanism.METHODS:Cultured IEC-6 cells were divided to 5 groups:control group, LPS (100 mg/L) group and LPS +Artemisinin (30, 50 and 100μmol/L) groups.The cytotoxici-ty was detected by MTT assay.The releases of TNF-α, IL-1βand IL-6 in the IEC-6 cells were measured by ELISA.The transepithelial electrical resistance ( TER) was detected by electrical resistance tester, and the horseradish peroxidase (HRP) flux permeability were analyzed by a microplate reader.The expression of tight junction proteins, ZO-1, claudin-1 and occludin, and the expression of TLR4/MyD88/NF-κB at mRNA and protein levels were determined by RT-qPCR and Western blot.RESULTS:Artemisinin alone (up to 100 μmol/L) or in combination with LPS (100 mg/L) was not toxic to IEC-6 cells.Compared with control group, the releases of TNF-α, IL-1βand IL-6 in the culture supernatant of IEC-6 cells significantly increased after treatment with LPS.The expression of TLR4/MyD88/NF-κB was activated by LPS.LPS down-regulated the protein expression of ZO-1, claudin-1 and occludin.However, artemisinin treatment decreased the re-leases of TNF-α, IL-1βand IL-6 in the culture supernatant of IEC-6 cells.The expression of TLR4/MyD88/NF-κB at mR-NA and protein levels was gradually reduced after treatment with artemisinin.In addition, artemisinin upregulated the pro-tein expression of ZO-1, claudin-1 and occludin significantly (P<0.01) in a dose-dependent manner.CONCLUSION:Artemisinin attenuates LPS-induced intestinal epithelial barrier damage by inhibiting TLR4/MyD88/NF-κB activation in the IEC-6 cells.

Objective To investigate the effects of ibutilide and amiodarone on the ventricular transmural heteroge-neity of repolarization and ventricular arrhythmia for the treatment of atrial fibrillation. Methods Eighty-seven patients with paroxymal atrial fibrillation at 48 h~7 d were enrolled and randomized to two groups, ibutilide and amiodarone treat-ment groups. The successful rate of cardioversion to sinus rhythm was compared between two groups. The electrocardiograph-ic QT interval and Tpeak-end/QT ratio were also analyzed before and after treatment in two groups. Results The successful rate of cardioversion was significantly higher in ibutilide group than that of amiodarone group (61.7%vs 40.7%, P＜0.05). The QT intervals and Tpeak-end/QT ratio were both significantly increased in ibutilide group (P＜0.05), which were re-turned to the levels before treatment in 2 hours and 1 hour, respectively (P＜0.05). The QT intervals were significantly in-creased in the amiodarone group (P＜0.01), which were continued until 4 h after treatment. There were no significant differ-ences in the Tpeak-end/QT ratios before and after treatment (P>0.05). Conclusion The successful rate of cardioversion to sinus rhythm for atrial fibrillation by ibutilide was significantly higher compared with that of amiodarone. Ibutilide slightly in-creased the transmural heterogeneity of repolarization within the first hour, which may increase the risk of ventricular arrhyth-mia.

AIM To explore the effects of glycyrrhetinic acid on the gastric ulcer rats infected by Helicobacter pylori (Hp) and its action mechanism.METHODS Gastric ulcer rat models were induced by acetic acid stress and then followed by Hp infection.After treatment with low and high doses of glycyrrhetinic acid,the ulcer index,gastric acid and proteinase activities in gastric ulcer rats were analyzed.The effects of glycyrrhetinic acid on the expressions of BCL2 and Caspase-3,the GSK3β activity in gastric mucosa and gastric epithelial cells,and the cell apoptosis level were then detected.RESULTS Glycyrrhetinic acid reduced the ulcer index,gastric acid and proteinase activities in rats.Besides,the expression of BCL2 was significantly up-regulated by glycyrrhetinic acid in gastric mucosa and gastric epithelial cells,whereas the expression of Caspase-3,level of cell apoptosis,and GSK3β activity were significantly reduced.After the treatment with GSK3 β activator LY294002,the level of BCL2 was down-regulated,Caspase-3 expression was increased,and the level of cell apoptosis was enhanced.CONCLUSION Glycyrrhetinic acid promotes the healing of gastric ulcer infected by Hp via regulating GSK3β activity and inhibiting apoptosis of gastric epithelial cells.

Cardiopulmonary resuscitation (CPR) is vital for cardio arrest victims; in this field, researches have been aiming at its mechanism, operation guidelines, new CPR machines and so on. This paper summarized the studies on the mechanical characteristics of the thorax under CPR, and on the simulation work of sternal-displacement relationship in CPR manikins. The data from modeling work showed that the thorax's sternal-displacement relationship could be graphically represented by a hysteresis curve. As the actual CPR manikins' mechanical structures of the thorax are too simplified, it is necessary to do the work of improvement.
