Objective To investigate the clinical characteristics,treatment and prognosis of myocardial damage presented with abdominal pain in children.Methods The clinical data of 33 children with myocardial damage presented with abdominal pain in Beijing Anzhen Hospital during the past 4 years were analyzed.Emergency conditions were ruled out in all cases.Results Among 33 cases with myocardial damage presented with abdominal pain,there were 10 cases of pneumonia,9 cases of acute bronchitis,7 cases of upper respiratory tract infection,1 case of allergic purpura,1 case of myocarditis and 5 cases of unknown causes.The duration of abdominal pain lasted 2 days to 3 months.The characteristics and the duration of abdominal pain were irregular.Mycoplasma antibodies positive were 5 cases (2 cases of bronchitis,3 cases of pneumonia).Coxvirus antibodies were 2 cases.There were different symptoms and signs of myocardial damage.Holter:there were ST-T changes in 23 children and 17 frequent premature ventricular complex(pattern of bigeminy and trigeminy in 7 children,premature atrial complex in 4 children).Creatine kinase isoenzyme-MB were high in 21 children(30-124 U?L-1).Cardiac troponin I were high in 19 children(0.8-1.2 ng?L-1).Chest X-ray:cardiomegaly was noted in 7 children,and the ratio of cardiac and chest were 0.55-0.58.Echocardiography:the left ventricular end-diastolic diameter was enlarged in 5 children,the right atrium was enlarged in 1 child.Most abdominal pain was relieved with treatment in 5 to 7 days,and 14 days was the longest.Total treatment course was 2 weeks to 1 month,and 3 months was the longest.But 1 case with myocarditis was recurrent abdominal pain treated nearly 3 months,and lasted to 6 months for recovery.Conclusions It is important to pay attention to cardial examination early,when a child becomes inconsolable from abdominal pain but emergency conditions should be ruled out.

Objective To investigate the situation of drug resistance and nosocomial infection of multi-drug resistant bacteria (MDR),guidance for clinical rational use of antibiotics.Methods A total of 1521 strains of MDR was isolated from January 2015 to December in Beijing Tongren Hospital,using matrixassisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) identification of bacteria,VITEK-2 Compact and Kirby Bauer (KB) method for drug sensitivity test.Results In 1 521 strains of MDR,Acinetobacter Baumanii were 589 strains (38.7％),nosocomial infection rate were 16.6％;350 strains of Escherichia coli (23.0％),nosocomial infection rate were 9.0％;249 strains of Staphylococcus aureus (16.4％),nosocomial infection rate were 2.7％;171 strains of Klebsiella pneumoniae (11.2％),nosocomial infection rate were 14.3％;150 strains of pseudomonas aeruginosa (9.9％),nosocomial infection rate were 64.7％;12 strains of Enterococcus faecium (0.8％),nosocomial infection rate were 16.7％.MDR Acinetobacter Baumanii,MDR Pseudomonas aeruginosa,extended-spectrumβ-lactamase (ESBL) + Escherichia coli and ESBL + Klebsiella pneumoniae resistance rate to Imipenem were 100％,91.5％,0.6％ and 55.6％.Conclusions MDR pseudomonas aeruginosa (MDR-PAE),MDR acinetobacter baumanii (MDR-AB) and ESBL + Klebsiella pneumoniae were highly resistant,and the nosocomial infection rate were higher.

OBJECTIVE:To explore the efficacy and safety of probucol combined with butylphthalide in the treatment of pa-tients with acute cerebral infarction. METHODS:172 patients with acute cerebral infarction were randomly divided into observation group and control group,86 cases in each group. All patients received conventional treatment for acute cerebral infarction,includ-ing thrombolysis,anti-platelet aggregation,reducing intracranial pressure,nutritional support,intensive lipid-lowering within onset 4.5 h,timely treatment of the underlying diseases;based on it,control group received Probucol tablet,0.5 g every times,bid. Ob-servation group additionally received Butylphthalide and sodium chloride injection,100 ml every times,bid,in 9:00 and 17:00 ev-ery day,infusion within 50-90 min. Both groups lasted for 2 weeks. Lipid metabolic indexes,the changes of serum S100β,NSE and hs-CRP levels,NIHSS score,clinical efficacy before and after treatment,and the incidence of adverse reactions in 2 groups were observed. RESULTS:Compared with before treatment,triglyceride(TG),total cholesterol(TC)and low-density lipoprotein cholesterol (LDL-C) levels in 2 groups significantly decreased,high-density lipoprotein cholesterol level significantly increased, and TG,TC and LDL-C levels in observation group decreased more significantly,the differences were statistically significant(P<0.05). Serum S100β,NSE and hs-CRP levels and NIHSS scores in 2 groups significantly decreased,and NSE level NIHSS scores and in observation group decreased more significantly,the differences were statistically significant (P<0.05). The total effective rate in observation group was 89.5%,significantly higher than control group (62.8%),the difference was statistically significant (P<0.05). There were no obvious adverse reactions during treatment,and also no obvious liver and kidney function,blood coagula-tion and ECG changes. CONCLUSIONS:Probucol combined with butylphthalide can effectively improve the lipid metabolism and decrease serum NSE level in the treatment of patients with acute cerebral infarction,and plays positive role in early recovery of neu-rological function.

Bacillus cereus B-04 antagonist to Botrytis cinerea were isolated from samples of tomato soil infected by Botrytis cinerea in Zibo, which are identified through a series of morphological and biochemical characteristics and the sequence of 16SrDNA. Aiming at enhancing the inhibitory effect of this strain, a 4.1kb DNA fragment containing ?-1,3-glucanases gene from pUC1940 was inserted into vector pBE2 and pHY300PLK to construct recombination plasmids, PBE2-glu and pHY300PLK-glu, which were transferred into Bacillus cereus B-04, resulting in a new strain named B-04-glu. Restriction enzyme digestion and ?-1,3-glucanases plate culture confirmed that B-04-glu contained a functional ?-1,3-glucanases gene. Compared to the wild strain B-04, B-04-glu had an increased inhibitory effect against Botrytis cinerea on tomato.

Background Rare studies on the effect of statin on early stage of atherosclerosis have been repor- ted.Oxidative stress induced endothelial dysfunction may be the initiative factor for the development of atheroscle- rotic plague.Objective To investigate the mechanisms by which simvastatin,prevents atheroselerosis independ- ently of its lipid-lowering effect in Apolipoprotein E deficient mice.Methods Twenty-four 6 week old male apoE- deficient mice were randomly to receive placebo or simvastatin 5 mg/(kg?d)by gavage for 4 weeks.Total choles- terol(TC),super oxide dismutase(SOD),malondialdehyde(MDA)and serum nitric oxide(NO)were measured by biochemical analysis.Endothelium was observed by HE dyeing.The expression of caveolin-1 in aortic wall was detected by immunohistochemistry.Results There was no significant difference in serum TC between control and simvastatin treatment groups.Simvastatin caused less damaged endothelium(33.33% vs control's:75%,P

Objective To investigate the relationship among methotrexate(MTX) plasma concentration,dosage,clinical effecicy and toxicity, and to evaluate it′s clinical significance.Methods MTX was measured by a flurorescence polarization immunoassay in plasma samples obtained from acute lymphoblastic leukemia(ALL) patients treated in different doses of MTX, and these results were analyzed combined with clinical manifestations.Results 1.The average of plasma concentration at 24 hours increased with the increasing doses of MTX. The relapse rate decreased with increased plasma concentration;2.The cerebrospinal fluid(CSF) concentrations prior to the intrathecal MTXinstillation were all below the effective concentration, so the intrathecal MTX instillation was needed;3.No severe toxicity was observed in the study, because the plasma concentration was below the high risk.Conclusion The study of MTX plasma concentration provides us an objective basis for the individualized chemotherapy.

Objective To explore the immunophenotype of children with acute myeloid leukemia(AML) and its clinical significance.Methods Statistics was used to analyze the relationship between the immunophenotype of AML and their French-American-Britain(FAB) classification,complete remission (CR) in one month and 3-years event-free survival(EFS).Results CR rate was 71.6% and 3-years EFS rate was 50.8%. HLA-DR and CD34 absent mainly in M3, associated with higher CR and EFS rate. So did CD33 negative cases, especially in M2. CD13 positive was significantly predictive factor for achieving CR.Co-expression of lymphoid antigens and NK cell antigens(CD56) with M2 which correlated with lower CR and EFS rate.Conclusions The negative of HLA-DR, CD34, CD33,as well as CD13 positive, have relationship with good prognosis. Lymphoid antigens and CD56 are poor prognostic factors.
