OBJECTIVE To investigate the resistance rates of Gram negative bacilli and the distribution of ?-lactamases in hospital infections(HI) or community acquired infections(CAI) in Tongling.METHODS Antimicrobial(susceptibility)(test) was done on 356 strains of Gram negative bacilli isolated in Tongling from Oct 2003 to Sep 2004 by Kirby-Bauer method.The detection of ESBLs and AmpC ?-lactamases was performed by three-dimensional test,MBL by the double-disk synergy test.RESULTS Among total 356 strains of Gram negative bacilli,267 were with HI(53.9%) isolated from sputum of patients,89(34.8%) were(isolated) from CAI patients and urine.The antimicrobial susceptibility rates of Gram negative bacilli from CAI patients was significantly higher than that from HI patients,for Acinetobacter baumannii they were 1.5 to 3.0,for(Pseudomonas aeruginosa) were 1.2 to 1.6.No strains of Escherichia coli and Klebsiella pneumoniae were found resistant to imipenem.Among 356 Gram negative bacilli,77 strains hyperproducing ESBLs and AmpC ?-lactamases,the detection rate was 21.6%, 69 strains were isolated from HI patients,and 8 strains were from CAI patients.From strains resistant to imipenem had 13 strains detected MBL,the detection rate was 52.0%.All of them were isolated from HI patients.CONCLUSIONS The resistance of Gram negative(bacilli) is a serious problem in Tongling.The antimicrobial(susceptibility) rates of Gram negative bacilli from CAI patients are significantly higher than those from HI patients.Gram negative bacilli produce all kinds of(?-lactamases,) such as ESBLs,AmpC(?-lactamases) and MBL.

The left ventricular systolic function before and after right ventricular pacing was studied in 26 patients by Doppler and M-mode echocardiography. The results showed that there were increases in cardiac output and heart rate, respectively (P

Objective: To study the examination of coronary sinus (CS) and blood flow by transthoracic echocardiography(TTE) and transesophageal echocardiography(TEE).Methods: Thirty patients with supraventricular tachycardia were studied by TTE and TEE. The CS was visualized using modified 4 chamber view. The position of the probe was optimized until the coronary sinus with its ostium into the right atrium could be visualized. CS flow recordings were performed by TEE with Doppler sample volume placed in the CS within a distance of no more than 10 mm from its ostium. Results: In all patients the angle between the doppler beam and the long axis of the CS was <30°. The CS was fully displayed in 18 patients by TTE and 28 patients by TEE. The length and width of the CS were (16.53±2.57) mm and (4.51±1.30) mm by TTE, (24.11±2.46) mm and (5.06±0.97) mm by TEE.The CS flow was characterized by biphasic flow.Its flow velocity was (39±7.8), (31±6.1) and (21±4.7) cm/s respectively. The CS flow velocity-imeintegral was(43±11.6),(43±13.0),(27±8.2) cm/s. Conclusion: Echocardiography is reliable for detecting CS and its flow. TTE is more feasible for detecting CS and its flow than TEE.

Objective To examine clinical significance and relativity of heart-type fatty acid binding protein (H-FABP) and high-sensitivity C-reactive protein (hs-CRP) in patients with chronic heart failure. Methods Ser-um concentrations of H-FABP and hs-CRP were measured in 60 patients with chronic heart failure and 30 control subjects. Left ventricular ejection fraction (LVEF) was examined by Doppler echocardio graphic in all subjects. Re-sults Serum concentrations of H-FABP and hs-CRP were higher in patients with chronic heart failure than in con-trol subjects[(6.11±1.49)μg/L vs (4.24±1.40)μg/L,and (12.77±3.65)mg/L vs(4.85±1.35) mg/L,t=5.746 and 7.543,P<0.01] but LVEF was lower in patients with chronic heart failure than in control subjects [(42.13±6.55) % vs (61.50±3.89) %,t=-14.902,P<0.01]. In CHF subgroups,H-FABP and hs-CRP lev-el increased with advancing NYHA class (F=26.288 and 351.784,P<0.01) but LVEF decreased (F=252.834,P<0.01). The serum H-FABP concentrations had a positive correlation with serum hs-CRP concentrations (r=0.801,P<0.01),and a negative correlation with LVEF (r=-0.718,P<0.01) ;serum hs-CRP concentrations had a negative correlation with LVEF(r=-0.881,P<0.01). Conclusion Serum H-FABP and hs-CRP levels are in-creased with the worsening of CHF. H-FABP and hs-CRP level are pnsitiviely related. The quantitative determination of serum concentrations of H-FABP and hs-CRP is valuable for risk stratification in patients with chronic heart fail-ure.

Compared with the transgenic approach, transient assays provide a convenient alternative to analyze gene expression. To analyze the relationship between miRNAs and their target genes, a rice protoplast system to detect target gene activity was established. The MIRNA and GFP-fused target sequence (or GFP-fused mutated sequence as a non-target control) were constructed into the same plasmid, and then delivered into rice protoplasts. The GFP expression level decreased significantly when the protoplasts were transfected with the plasmid containing GFP-fused target compared to that of the plasmid with non-target sequence either by fluorescence microscopy or qRT-PCR method. Two microRNA genes, osaMIR156 and osaMIR397, and their target sequences were used to prove the feasibility of the rice protoplast transient assay system. This method will facilitate large-scale screening of rice miRNA target in vivo, and may be suitable for functional analysis of miRNAs of other monocot plants that might share the evolutionarily conserved small RNA processing system with rice.

Evidence-based medicine is advocated by WHO and adopted by developed countries for many years. In China, however, the selection of essential medicine and various medical insurance reimbursement schemes medicine is usually based on experts' experience of prescription practice which is under heavy critics resulting from the lack of related comparative efficacy and evidence-based research. The efficacy of Jian'ganle in prevention of drug-induced liver injury (DILI) caused by antituberculotics was evaluated in this study by comparison with Hugan Pian, glucuronolactone and reduced glutathione. Evidence was provided for relevant sectors such as Ministry for Human Resources and Social Security of the People's Republic of China and National Health and Family Planning Commission of the People's Republic of China to select and renew the Essential Medicine List (EML), the new rural cooperative medical scheme in China (NRCMS) list or the reimbursement list of industrial injury insurance. A total of 189 patients with initial pulmonary tuberculosis were divided into four groups who took antituberculotics combined with Jian'ganle, Hugan Pian, glucuronolactone and reduced glutathione respectively. Their liver function profile including alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL), direct bilirubin (DBIL), total protein (TP), albumin (A) and globulin (G) were detected at admission as baseline and after treatment. The Jian'ganle group was compared with the three others by chi-square tests. In an aspect of maintaining bilirubin indexes normal, Jian'ganle was more efficacious than glucuronolactone. And Jian'ganle had a little more efficacy than reduced glutathione to maintain protein indexes normal as well. And the therapeutic regimen of antituberculotics combined with Jian'ganle was the best in treating tuberculosis and preventing DILI at the same time. The study showed that among the four hepatinicas which demonstrated similar prevention of DILI caused by antituberculotics, Jian'ganle has more advantages over the three others to some extent, which provides a reliable basis for health sectors to select and renew the EML, NRCMS List or the reimbursement list of industrial injury insurance.

OBJECTIVE To investigate the pathogenic causes of community-acquired pneumonia(CAP) in adult patients in Tongling.METHODS A prospective study was performed on 260 consecutive adult patients with CAP in Tongling city during last three years.Bacteria culture of sputum and serological tests in paired serum samples were detected.RESULTS Of 260 patients with etiological evaluation,128(49.2%) patients had an identifiable etiology,63(24.2%) had positive outcome from sputum cultured,atypical pathogens were detected from 75(28.8%)patients.Pathogens identified in 128 patients were:Mycoplasma pneumoniae(35.4%),Chlamydia pneumoniae(17.7%) and Streptococcus pneumoniae(13.6%).6.5% All patients had mixed infection.The resistance rate of S.pneumoniae to penicillin and erythromycin was 5 and 50%,respectively.CONCLUSIONS Atypical pathogens have important role in CAP,of which M.pneumoniae is the most common pathogen.S.pneumoniae and K.pneumoniae are the commonly encountered bacteria for CAP in Tongling.

Objective: To explore the blood velocity variety(BFV) of common carotid artery. Methods: BFV was detected with HDI5000 colour doppler ultrasound in 28 healthy volunteers to observe whether there was bifurcation among BFV of each section (about 6.0 cm) of common carotid artery(CCA). CCA was divided into 5 sections (1 cm) from its beginning to bifurcation. BFV was detected in each section. Influences of age, heart rate, blood pressure on BFV were observed. Results: BFV decreased gradually from its beginning to its divergence, the average decreasing value of each section BFV was 5.37 cm/s, and 4.24 cm/s, the difference between maximal and minimum BFV was 17.35 cm/s and 14.32 cm/s in right, left CCA respectively. Maximal BFV increased with age, blood pressure increased and heart rate decreased. But the change of each section BFV was not influenced by age, blood pressure and heart rate. Conclusion: The results indicate that each section BFV is not consistent in CCA, deviation is more obvious when stenosis is valued by internal carotid artery(ICA) BFV/CCA BFV, it should be valued with maximal BFV of ICA.

Objective To observe the influence of Epstein-Barr virus(EBV) infection on T cell subsets in children with infectious mononucleosis(IM).Methods Eighty children patients with IM in the Hanzhong Municipal People's Hospital from January 2013 to January 2016 were chosen as the study subjects and received the anti-virus therapy.The negative conversion rate of EBV-DNA after treatment was observed.The distributions of T cell subsets werecompared between the children patients with EBV-DNA positive and patients with EBV-DNA negative.The related factors of EBV-DNA non-negative conversion were analyzed.Results After treatment,67 children cases (83.75％) were EBV-DNA negative conversion.The proportions of CD3+ and CD8+ after treatment in the EBV-DNA negative group were lower than those in the EBV-DNA positive group,and the proportion of CD4+ and CD4+/CD8+ were higher than those in the EBV DNA positive group,the difference had statistical significance (P＜0.05).In the analysis on the related factors in the children patients with EBV DNA non-negative conversion,the gender,WBC count and lymphocyte count had no significant correlation with EBV-DNA negative conversion(P＞ 0.05),while interferon use,age and initial Ct demonstrated significant correlation with EBV-DNA non-negative conversion(P＜0.05).Conclusion EBV infection can lead to disturbance of T cell subsets in children with IM,so clinic should adopt an active anti-virus treatment.
