Objective To investigate the efficacy of flupentixol and melitracen(Deanxit) in treatment of non-erosive reflux disease(NERD) and non-responding to proton pump inhibitor. Methods Fifty eight NERD pa-tients were randomly divided into two groups, the treatment group (n = 29) and control group (n = 29). Patients in control group were given esomeprazole 40 mg qd. Patients in the treatment group were given the same drug plus Deanxit 1 Tab qd. The clinical effect was evaluated and scored by Hemihon Anxiety Rating Scale (HAMA) after 4 weeks. Results The total efficacy rate of the treatment group was higher than control group (P < 0.01),and HAMA was lower in the treatment group than in control group (P < 0.01). Conclusions Adjuvant treatment of Deanxit combined with esomeprazole is effective to NERD patients who did not respond to proton pump inhibitor, can greatly improve anxious disorders.

Objective:To observe the characteristics of 24 hour ambulatory electrocardiogram in patients with chronic atrial fibrillation (AF) and optimal ventricular rate control. 　　Methods:Holter monitoring was performed in 122 hospitalized patients,aged 17—85 (mean 51.57±11.94) years,with organic heart disease and chronic AF (New York Heart Association functional class Ⅱ-Ⅲ) in whom the ventricular rate were well-controlled by digoxin.Maximum,minimum and mean ventricular rates,the number of ventricular pauses of ＞1.5 second,and the longest ventricular pauses during the monitoring were recorded.Follow-up data were collected in 72 patients. 　　Results:The mean,fastest and lowest ventricular rates over 24 hours were 78.53±8.12(65—90)，143.79±28.85(90-183) and 51.04±7.52(34—71) bpm,respectively.Bradycardia of less than 50 and 45 bpm occurred in 62 and 32 of the 122 patients,respectively.Ventricular pauses of more than 1.5 and 3.0 seconds were noted in 95 and 14 of the 122 patients,respectively.The longest ventricular pause was 2.38±0.55(4.64—1.60) seconds.During follow-up,there were no worsening in these patients. 　　Conclusion:Ventricular pauses at rest and nocturnal bradycardia were common in patients with chronic atrial fibrillation who had ventricular rates controlled.The dosage of digoxin should not be changed,nor pacemaker insertion is needed.

Objective To analyze the family and clinical characteristics of talking about killing self (TAKS) among children and adolescents and its relationship with social competency.Methods One thousand nine hundred and seventy-five 7-17-year-old students from 12 schools (each four for primary,middle and high schools) of Wuhan area,were approached through multistage random cluster sampling,and administered with a self-designed general information questionnaire and the Chinese version of Children' s Depression Inventory.In addition,subjects' parents completed Achenbach' s Child Behavior Checklist (CBCL).TAKS was judged based on item 91 (talk about killing self) of CBCL.Multiple Logistic Regression was used to identify factors associated with TAKS.Results The half-year prevalence rate (95％ CI) of parent-reported TAKS was 4.1％ (3.2％,5.0％).TAKS was significantly associated with bad marital status of parents (OR=2.29),unemployment of fathers (OR=2.07),frequently jangling between father and mother (OR=2.23),parents ever having fought with each other intensely (OR=2.00),being frequently bullied by classmates (OR=2.11),internal behavior problem (OR=2.28),external behavior problem (OR=2.50) and depressive symptoms (OR=4.83).TAKS subjects had significantly lower social compctency score than non-TAKS subjects((18.8±7.6) vs.(20.9±6.9),P=0.007).Conclusion The prevalence of TAKS is higher among children and adolescents with several disadvantaged family factors,behavior problems and depression.Children and adolescents with TAKS also have worse social competency.More close clinical attention should be paid to such phenomenon.

Objective To establish a method for rapid diagnosis and identification of seven species human herpesviruses infection.Methods Primers and oligonucleotide probes were designed and synthesized based on the highly conserved regions of the DNA polymerase genes in human herpesviruses, namely herpes simplex virus type 1 (HSV-1),HSV-2,varicella-zoster virus (VZV),Epstein-Barr virus (EBV),cytomegalovirus (CMV),and human herpes virus 6 (HHV-6A/6B).DNA microarrays were made by printing the oligonucleotide probes on the special glass slides.A total of 282 blood specimens from children with suspected infection were analyzed by this DNA microarray technique,and the results were compared with those of TaqMan PCR.Results The products of the seven human herpesviruses after PCR amplification could be used to identify the virus species with DNA microarrays.The detection limits were 10 copies/?l for HSV-1,HSV-2,VZV,EBV,CMV,HHV-6A,and HHV-6B,respectively.The assay did not show cross-reaction to the DNA extract of hepatitis B virus,staphylococcus aureus,E.coli,Candia albicans and human genome.Among the 282 samples,59 were positive for human herpesviruses DNA.Compared with those of TaqMan PCR,the sensitivity and specificity of the microarray assay were 96.7% and 99.5%,respectively,and the index of accurate diagnosis was 0.962.Conclusions This DNA microarray for identifying human herpesviruses species is specific and sensitive,and may serve as an efficient technique for simultaneous detection and species identification of human herpesviruses in clinical specimen.

This retrospective analysis showed that the most frequent pathogen causing bacterial liver abscess was Klebsiella pneumoniae in 138 patients.Compared with the patients without diabetes mellitus,it was found that:( 1 ) the percentage of diabetic patients having typical abdominal pain was lower ( P ＜ 0.05 ) ; ( 2 ) neutrophilic granulocytosis was more marked,but albumin and hemoglobin levels were lower in diabetic patients( P＜0.05 ) ; ( 3 )more diabetic patients were complicated with urinary tract infection and suffered from septicemia( P＜0.05 ) ; (4) the clinical course of treatment in diabetic patients was much more prolonged( P＜0.05 ).

BACKGROUND: The intraocular lens can move forward during cataract optic capsular surgery,but the changes in the human eye diopter cannot be monitored in such a dynamically adjustment process,it is difficult to obtain clinical data which could reveal the correlation between intraocular lens forward and human eye diopter adjustment.OBJECTIVE: To observe the influence of intraocular lens movement on the adjustment of human eye diopter.METHODS: Based on Hwey-Lan Liou eye model,using optical design software ZEMAX to realize ray tracing,the relationship of intraocular lens forward in the eye with the adjustment of human eye diopter was investigated.RESULTS AND CONCLUSION: Once the intraocular lens forward for a certain distance,human eye obtained the amount of accommodating diopter was not constant; the adjustment amount depended on the axial length and the required intraocular lens implantation,especially in axial length; for the intraocular lens forward of the surgical eyes at different axial lengths,the amount of accommodating human eye diopter was negatively correlated with axial length.

Objective:To study the predictive value of red cell distribution width (RDW)on poor myocardial perfu- sion in patients with acute myocardial infarction(AMI)treated by percutaneous coronary intervention (PCI).Meth-ods:From August 2013 to August 2015,a total of 212 ACS patients undergoing PCI in our hospital were selected. According to RDW of blood analyzer,patients were divided into RDW<13.0% group (n=115)and RDW≥13.0%group (n=97).According to ST segment regression rate (STR)on single lead of ECG 1~2h after PCI,patients with STR≤50% were enrolled as poor myocardial perfusion group (n=78)and those with STR>50% were regar- ded as good myocardial perfusion group (n=134).Clinical data were compared between two groups,and single fac- tor and multi-factor analysis were used to analyze influencing factors for myocardial perfusion.Results:Compared with RDW<13.0% group,there were significant rise in age [(62.85±5.23)years vs.(67.33±6.17)years],and significant reductions in left ventricular ejection fraction [LVEF,(52.37±6.14)% vs.(50.55±5.53)%]and STR [(0.73±0.26)vs.(0.57±0.39)]in RDW≥13.0% group,P<0.05 or <0.01. Compared with good myocardial perfusion group,there were significant reductions in percentage of RDW<13% (59.70% vs.44.87%)and LVEF [(52.25±3.81)% vs.(50.29 ± 4.08)%],and significant rise in age [(63.29 ± 1.93)years vs.(66.42 ± 2.15) years]in poor myocardial perfusion group,P<0.05 all.Multi-factor Logistic regression analysis indicated that age, LVEF and RDW were independent predictors for poor myocardial perfusion (r=3.826~6.525,P<0.01 all).Con-clusion:Red cell distribution width possesses good predictive value for poor myocardial perfusion in patients with a- cute myocardial infarction undergoing percutaneous coronary intervention,which is worth extending in clinic.

Objective To explore the value of sonogram index scoring system in the prenatal diagnosis of trisomy 18 syndrome.Methods Neonates who had prenatal sonographic screening in our tertiary center were followed up from January 2004 to December 2009.The fetuses who were suspected with abnormalities received karyotype analysis.All fetuses were divided into case group ( trisomy 18 group) and the control group (non-trisomy 18 group).The latter group was constituted of fetuses with trisomy 21,trisomy 13,other chromosomal abnormalitis and fetuses with normal karyotype.Logistic regression analysis was done to decide the individual sonographic features of trisomy 18.A score was assigned for ultrasound markers according to their likelihood ratios for trisomy 18 syndrome.A score of 3 was assigned for the sonographic features with likelihood ratio over 200,2 for those with likelihood ratio between 100 and 200,and 1 for those with likelihood ratio less than 100.The diagnostic efficacy of the ultrasound index scoring system was evaluated by diagnostic test.The optimal cutoff value was determined by receiver operating characteristic (ROC) curve.Results The study group included 59 fetuses with trisomy 18.And 26 486 fetuses did not have trisomy 18 syndrome,including 93 fetuses with trismoy 21,19 fetuses with trisomy 13,134 fetuses with other chromosomal abnormalities,3739 fetuses with normal karyotype and 22 501 fetuses with normal appearance after birth.Two or more structural defects were observed in each trisomy 18 fetus.The highest incidence of sonogram abnormalities was extremities abnormalities (85％,50/59 ),followed by cardiac defects (83％,49/59) and central nervous system (CNS) malformations (75％,44/59).Overlapping fingers,ventricular septal defect and strawberry-shaped skull were the most common abnormalities in extremities abnormalities,cardiac defects and CNS malformations,respectively.Logistic regression identified 16 markers,including choroid plexus cyst,strawberry-shaped skull,enlarged cisterua magna,holoprosencephaly,low-set ears,ventricular septal defect,hypoplastic left heart syndrome,etc.Different scores were assigned according to the likelihood ratios of these markers.In trisomy 18 group,fetuses with the sonographic score of 1,4,9,10 to 16 were 2％ ( 1/59),9％ (5/59),10％ (6/59) and 32％ (19/59) respectively,whereas in non-trisomy 18 group they were 2.549％ (675/26 486),0.215％ (57/26 486),0.004％ ( 1/26 486) and zero,respectively.When a score of 4 was used as the cutoff value for diagnosing fetal trisomy 18,the sensitivity and specificity were 0.966 and 0.997,respectively.The area under ROC curve was 0.999.Conclusions The ultrasound index scoring system may help to quantify the ultrasound features and has a good diagnostic value for fetal trisomy 18 syndrome.The cutoff value of 4 has the best diagnostic efficacy.

Objective To investigate the effects of methylated CpG islands in the promoter region on the expression of killer cell immunoglobulin-like receptor 3DL1 (KIR3DL1).Methods Three voluntary unpaid blood donors carrying high expression allele KIR 3DL1*01502 and three donors carrying low expres-sion allele KIR3DL1*005 were recruited in this study .The nucleotide sequences and the methylated CpG islands in the promoter regions of KIR 3DL1*01502 allele and KIR3DL1*005 allele were analyzed .The NK cells expressing KIR3DL1*01502 and KIR3DL1*005 were respectively treated with 5-aza for the dem-ethylation of CpG islands within the promoters .The expression of KIR3DL1 protein on the surface of NK cells was measured with flow cytometer .Results Two differences at nucleotide sites -65 and -269 were detected within the promoter regions of KIR3DL1*01502 and KIR3DL1*005, resulting in two distinct CpG islands.The CpG islands within the promoter of KIR 3DL1*01502 allele were highly methylated .The ex-pression of KIR3DL1 protein on NK cells which carried KIR 3DL1*01502 allele was significantly increased after the demethylation of CpG islands .However , the treatment of demethylation had no significant effects on the expression KIR3DL1 protein on NK cells harboring KIR3DL1*005 allele.Conclusion The methylated CpG islands within the promoter of KIR 3DL1*01502 allele affected the antigen expression on the surface of NK cells.Different KIR3DL1 alleles might show different mechanisms in regulating antigen expression .
