Objective To determine,the clinical significance of serum myocardial enzymes (Mb,cTNI, CK,CK-Mb,AST,LDH) in the classification of the disease severity of non-cardiogenic critically-ill patients. Compared with APACHEⅡscore concerned as the standard diagnosis of the critical ills,these biomarkers were investigated for the evaluation possibility of the degree and the prognosis of the critical ills.Method Patients admitted to our EICU were consecutively collected for the research from April to December in 2005 and the myocardial enzymes,and routine serum biochemical test and APACHEⅡscore were detected simultaneously.All the patients were classified to three groups according to the APACHEⅡscore (mild group,APACHEⅡ25) and two groups (survive group and death group) according to the prognosis.All the patients were followed up till recovery/discharge or death. Covariance,Wilcoxon and x~2 were used for the statistical analysis.Results The myocardial enzymes rose when the disease deteriorated and the APACHEⅡscore went up.AST,LDH,CK,CK-Mb,Mb were significantly different in the three groups according to the APACHEⅡscore (P

Objective To study the curative effect and adverse reaction of Oxcarbazepine(OXC)on treating epilepsy in children.Me-thods One hundred and twenty-nine children with different types of epilepsy were orally given OXC,and the drug dose was added gradually.According to the seizure frequency,the cases were divided into 2 groups.Group A:more than 3 seizures occurred in 3 months prior to to take OXC;group B:more than 3 seizures occurred in 1 year prior to taking OXC.After 5 months and 1 year from beginning to take OXC,the original curative effect of the 2 groups was evaluated,respectively;on the other hand,the adverse reaction and the retention were studied.Results 1.Original effect:the rate of seizure-free was 45.8% and the total curative efficiency was 66.7% in group A(n=47);the rate of seizure-free was 92.3% in group B(n=13);in 60 partial epilepsy children,the rate of seizure-free was 56.7% and the total curative efficiency was 73.3%;Both rates were 62.2% and 75.6% of patients with OXC monotherapy and 40%,66.7% of patients were given OXC in combination with another antiepileptic drugs.2.Drug adverse reaction:24% of patients were found to have adverse reaction and most of the symptoms were light and most transient.3.Tolerability:patients' retention of OXC in 1 year was 72.2%,and in 2 years was 80.0%.Conclusions The antiepileptic effect of OXC is satisfactory and adverse reaction is light and mostly transient,OXC as a new antiepileptic drug is well tolerated as monotherapy and adjunctive therapy and should be used extensively.J Appl Clin Pediatr,2009,24(1):53-55

Objective To analyze the treatment outcome and related influencing factors of Tibet- an nationality new smear-positive pulmonary tuberculosis patients in Qinghai Province，so as to provide evidence for tuberculosis control and treatment among Tibetan population． Methods Statistical analysis was conducted on 5 564 Tibetan nationality new smear-positive pulmonary tuberculosis cases in Qinghai province who were reported in the China Tuberculosis Information Management System and approved to receive treatment from 2008 to 2017． The main influencing factors were detected by unconditional Logistic regression model analysis，dependent variable was successful treatment or not，independent variables were other factors related to the treatment outcome． Ｒesults The treatment success rate of Tibetan nationality new smear-positive pulmonary tuberculosis cases was 87. 1% ( 4 848 /5 564) ，and the adverse outcome rate was 12. 9% ( 716 /5 564) ． Unconditional Logistic regression model analysis indicated that non-full- course supervision management，living in agricultural and pastoral area，having severe disease，floating population，and age older than 60 years were risk factors of adverse outcome． The odds ratio( OＲ) 95% confidence interval( CI) of the above risk factors were 13. 044( 10. 671-15. 944) ，2. 305( 1. 703-3. 119) ， 2. 090( 1. 346-3. 243) ，1. 967( 1. 443-2. 682) ，and 1. 909( 1. 410-2. 586) ． Clinical consultation，farmers and herdsmen were protective factors． The OＲ( 95% CI) were 0. 451( 0. 375-0. 543) ，and 0. 786( 0. 627- 0. 985) ． Conclusions Treatment success rate of Tibetan nationality new smear positive pulmonary tuberculosis cases was low． Therefore，the directly observed treatment short-course ( DOTS) strategy should be strictly implemented and the full-course supervision management should be strengthened to improve the treatment success rate． More attention should be paid to the elderly，severe，floating，agricultural and pastoral populations among the Tibetan population．

In order to evaluate the effect and mechanism of the mulberry leaf alkaloid, flavones, and polysaccharide intervention on diabetes, the overall metabolite profiling characteristics for the plasma of diabetic mouse was performed by using an ultra-performance liquid chromatography/electrospray-tandem mass spectrometry (UPLC-ESI-MS). The 8 potential biomarkers were found in diabetic mice plasma based on the data of MS/MS characteristics obtained from the UPLC-OrbitrapMS analysis, which mainly involved in sphingolipids, amino acid metabolic pathway. The principal component analysis showed that the normal group and model group were obviously distinguished and implied that metabolic disturbance was happened in diabetic mice plasma. The extracts of mulberry leaf flavonoids, polysaccharide, alkaloid had exhibited the effects of callback function for diabetic mice through regulating the amino acid metabolism and sphingolipid metabolism.

OBJECTIVETo study the cognitive function, its correlation with and the impact on quality of life in epileptic children aged 6-13 years in regular school.

METHODCognitive function of 172 children with various types of epilepsy were measured using a computerized neuropsychological test battery including six items. Their scores across the neuropsychological measures were compared with 172 healthy control subjects from the general population strictly matched for age, sex and the region where education was accepted. The quality of life was measured in 105 cases by the Quality of Life in Epilepsy Inventory (QOLIE-31).

RESULT(1) After adjusting for age, gender, and education, children with epilepsy performed significantly worse than healthy control subjects on 5 of 6 cognitive tasks, including Raven's progressive matrices correct number (8.6 vs. 14.0), choice reaction time (620.4 ms vs. 489.5 ms), word-rhyming tasks (2796.9 ms vs. 2324.4 ms), simple substraction correct number (28.6 vs. 35.5)as well as number comparision (1002.4 ms vs. 803.1 ms), P < 0.01. When an impairment index was calculated, 44.2% patients had at least one abnormal score on the test battery, compared with 14.5% of healthy volunteers, there was statistically significant differences between the two groups, P < 0.001. (2) Children with new onset epilepsy before the treatment with anti-epilepstic drugs performed significantly worse than healthy controls on 5 of 6 cognitive tasks, including Raven's progressive matrices correct number (9.1 vs. 13.8), choice reaction time (625.8 ms vs.474.5 ms), word-rhyming tasks(3051.8 ms vs. 2575.4 ms), simple substraction correct number (28.9 vs. 35.3) as well as number comparison (942.4 ms vs. 775.8 ms), P < 0.01. (3) Cognitive performance was not related to the age of onset, type of epilepsy, therapy duration or comorbid emotional and behavior disorders, P > 0.05. (4) 105 cases filled in the QOLIE-31 questionaire, the total score of the quality of life in the group without cognitive impairment and psychical conditions was the highest (60.5 ± 0.9), and the lowest total score was found in group with cognitive impairment and psychical conditions (54.6 ± 1.5), there were highly significant differences between the groups, P < 0.001.

CONCLUSIONAlmost one-half of the children with epilepsy accepting regular education had at least one abnormal score in the battery tests. Newly diagnosed untreated patients with epilepsy are cognitively compromised before the start of antiepileptic drug medication. Cognitive impairment was not related to the epilepsy-related or psychiatric variables. Cognitive impairment and mental disorders require further attention and essential therapy, which is important to the improvement of the quality of life in epileptic children.

OBJECTIVETo find out the rate of comorbidities of depression, anxiety disorder and attention deficit hyperactivity disorder (ADHD) symptoms in children with epilepsy and to analyze the relevant affecting factors and impacts on quality of life.

METHODTotally 142 children with various types of epilepsy underwent neuropsychological assessment with the Depression Self-rating Scale for Children, the Screen for Child Anxiety Related Emotional Disorders and the ADHD Rating Scale-IV, an 18-item parent-rated questionnaire based on the diagnostic criteria for ADHD, the quality of life was measured in 100 cases on antiepileptic medications by the Quality of Life in Epilepsy Inventory (QOLIE-31). The comorbidity rates were calculated using t-test, chi(2) test and multiple logistic analysis, the variables associated with psychiatric comorbidities were determined, and the impact on quality of life was analyzed.

RESULT(1) The total rate of emotional and behavioral comorbidities was 57.7% (82/142), the frequency of depressive disorder, anxiety disorder and ADHD was 14.8%, 44.4% and 17.6%, respectively. The suicidal ideation occasionally occurred in 5.6% of the cases and 0.7% of cases often had the ideation, but no suicidal action was found in any case. (2) Risk factors for the emotional and behavioral disorders: multiple logistic analysis indicated that age, gender and epilepsy illness-related variables were not relative to the comorbidities, P > 0.05, there were interactions among the disorders. (3) The impact on the quality of life: The emotional and behavioral conditions were associated with the low quality of life, which was significantly lower in epileptic children with co-morbid disorder compared to non-comorbidities epilepsy group. Especially negative impact on the total score of quality of life and four sub-items such as overall quality, emotional well-being, cognitive and social function, P < 0.001. There were also significant differences between the two groups in the other three sub-items including fear for seizure attack, energy/fatigue and medication effects (P < 0.05).

CONCLUSIONSThe frequency of emotional and behavioral disorders including depress disorder, anxiety disorder and ADHD was considerably high in children with epilepsy. Age, gender and epilepsy illness-related variables are not associated with the emotional and behavioral comorbidities, which interfere with each other. Emotional and behavioral disorder is one of the negative factors to the quality of life in epileptic patients. Neuropsychological assessment and treatment are important for improvement of the quality of life in children with epilepsy.

BACKGROUNDMultidrug-resistant Acinetobacter baumannii (MDRAB) is an important and emerging hospital-acquired pathogen worldwide. This study was conducted to identify the sources of MDRAB and its role in respiratory tract colonization and nosocomial pneumonia in intensive care unit (ICU) patients.

METHODSWe conducted a prospective active surveillance study of MDRAB in three ICUs at a Chinese Hospital from April to August 2011, to identify the sources of MDRAB and its role in respiratory tract colonization and nosocomial pneumonia.

RESULTSOne hundred and fourteen (13.0%) MDRAB isolates were detected from 876 specimens, with a sensitivity of 11.6% (55/474) in screening of the pharyngeal and tracheal swabs, and 14.7% (59/402) of the sputum/endotracheal aspirates. MDRAB colonization/infection was found in 34 (26.8%) of 127 patients, including 16 (12.6%) cases of pure colonization and 18 (14.2%) cases of pneumonia (two pre-ICU-acquired cases of pneumonia and 16 ICU-acquired cases of pneumonia). Previous respiratory tract MDRAB colonization was found in 22 (17.3%) patients: eight (6.3%) were pre-ICU-acquired colonization and 14 (11.0%) ICU-acquired colonization. Of eight pre-ICU-colonized patients, five were transferred from other wards or hospitals with hospitalization > 72 hours, and three came from the community with no previous hospitalization. Overall, 6/22 colonized patients presented with secondary pneumonia; only two (9.1%) colonized MDRAB strains were associated with secondary infections. Respiratory tract MDRAB colonization had no significant relationship with nosocomial pneumonia (P = 0.725). In addition, acute respiratory failure, mechanical ventilation, renal failure, and prior carbapenem use were risk factors for MDRAB colonization/infection.

CONCLUSIONSA high proportion of cases of MDRAB colonization/infection in ICU patients were detected through screening cultures. About one-third were acquired from general wards and the community before ICU admission. The low incidence of MDRAB colonization-related pneumonia questions the appropriateness of targeted antibiotic therapy.

In order to investigate expressions of transcription factor GATA-1 and GATA-2 genes in the bone marrow stromal cells (BMSCs) from patients with leukemia or normal controls, bone marrow stromal cells from 34 normal cases and 42 cases with leukemia were cultured long-term in vitro. Nonadherent cells (bone marrow hematopoietic cells) and amplified adherent cells (BMSC) were collected separately. Expressions of GATA-1 and GATA-2 genes were analyzed by using RT-PCR-ELISA; the semi-quantitative expression levels of GATA genes in the BMSCs from patients with leukemia were compared with normal controls. The results showed that expressions of GATA-1 and GATA-2 genes could be detected in the BMSCs and the bone marrow hematopoietic cells from both normal controls and the cases of leukemia. The expression ratio of GATA-1 in the BMSCs from acute lymphocytic leukemia (ALL) (85.7%) was similar to the normal controls (88.2%), whereas the expression ratios in BMSCs from acute myelocytic leukemia (AML) (55.6%) and chronic myelocytic leukemia (CML) (41.2%) were significant lower than the normal controls (P < 0.05). The rank of expression level of GATA-1 gene in the BMSCs was "ALL>AML>normal>CML". There was no difference in the expression level of GATA-2 gene within the BMSCs from normal controls and patients with leukemia. The ranks of expression levels of GATA-1 and GATA-2 genes in bone marrow hematopoietic cells were "AML>normal>ALL>CML" and "AML>CML>ALL>normal". The dominant expression of GATA-2 gene was found in the BMSCs from AML, CML or normal controls. It is inferred that the expressions of GATA-1 and GATA-2 genes in the BMSCs of normal controls and patients with leukemia may influence the regulation of hematopoiesis in the bone marrow stroma and it is worthy of further study to explore their roles in pathogenesis and development of leukemia.
