Objective To observe the clinical efficacy of acupuncture in treating functional dyspepsia. Method Sixty-eight patients with functional dyspepsia were randomized into an acupuncture group and a control group. The acupuncture group was intervened by matrix needling, once a day, 8 d as a course, with a 2-day interval between two courses, for successive 4 weeks. The control group was prescribed with Motilium at 10 mg, 3 times a day, for successive 4 weeks. Result The total effective rate was 91.4% in the acupuncture group versus 87.9% in the control group, and the difference was statistically insignificant (P>0.05); there was a significant difference in abdominal pain score between the two groups (P<0.05), indicating that the acupuncture group should be superior to the control in releasing abdominal pain. Conclusion The overall efficacies in treating functional dyspepsia are equivalent between the acupuncture group and control group, but the acupuncture group is better than the control in releasing pain. Therefore, compared to medicine, acupuncture has advantage in treating functional dyspepsia.

Objective To observe the pathogens and drug-resistance of ventilator-associated pneumonia (VAP) patients in emergency intensive care unit (EICU) for rational antibiotic therapy and the prevention of VAP. Method The sputum culture results and drug-resistance of pathogens of VAP patients in EICU from 2007 to 2009 were collected. Results One hundred and two mechanical ventilation patients were selected. VAP was occurred in 70 patients (68.6%). One hundred and fifty-seven pathogens had been examined,including 92 Gram-negative bacilli (58.6%),35 Gram-positive cocci (22.3%) and 30 fungus (19.1%). Pseudomonas aeruginosa and meticillin-resistant-staphylococcus aureus was 22 strains (14.0%)respectively, stenotrop homonas maltophilia was 21 strains (13.4%) and acinetobacter baumanii was 17 strains (10.8%). Fifty-nine patients (84.3%) had suffered from multiple pathogen infection, with 31 cases having 2 pathogens and 28 cases having 3 pathogens. Conclusions Pseudomonas aeruginosaa,methicillinresistant staphylococcus, stenotrophomonas maltophilia and acinetobacter baumanii are main pathogens of VAP in EICU patients,and candida albicans is still the main pathogens in fungal infection. The rate of multiple pathogen infection is very high, and the problem of drug-resistance is very severe.

Objective To explore cephalosporinase from nosocomial Klebsiella pneumoniae infection and their drug-resistant characteristics among the ICU patients so as to provide an instruction for rational clinical medication.Methods 67 samples were identified with VITEK-60 automated system.The strains producing AmpC β-lactamases were screened with cefoxitin disk diffusion method recommended by the CLSI,and confirmed by cefoxitin three-dimensional test.AmpC β-lactamase genotype was differentiated by PCR-sequencing and susceptibility tests which were done with the Kirby-Bauer method recommended by the CLSI.Results In the 67 isolates of Klebsiella pneumoniae,11 strains(16.4％) were found to produce AmpC β-lactamases.The drug-resistant genotype for all the 11 AmpC-positive strains was DHA-1.AmpC-producing strains developed multi-drug resistance,especially for broadspectrum β-lactam antibiotics and enzyme inhibitors.β-lactamases-producing strains were more resistant than non-producing ones.Conclusion Klebsiella pneumoniae in ICU patients has a higher proportion of producing AmpC β-lactamase strains,which are all of DHA-1 genotype and have multi-drug resistance.

Objective]To explore the relationship between Yin-wei theory and clinical practice ,and to discuss how to apply Yin-wei theory to solve practical problems in clinical situation.[Methods]We start from the Traditional Chinese Medicine(TCM) classics Nei Jing(the Canon of Internal Medicine) and Nan Jing(Canon On Eighty-One Difficult Issues),combined with Zhang Zhongjing’s application of Guizhi decoction in his book“Treatise on Febrile and Miscellaneous Diseases”to explore the cause and effect of Yin-wei theory and to comprehensively analyze its underlying thought .[Results]We found that Guizhi decoction in the“Treatise on Febrile Diseases”was not only applied in the chapter Taiyang disease,but also involved in other four chapters of Shaoyin disease and the chapter of cholera disease.In“Synopsis of Golden Chamber”,Guizhi decoction was used to treat vomitus gravidarum and affection by cold after delivery,while in Zhongjing’s practice,Guizhi decoction derived formula was widely used in the treatment of consumptive internal injuries miscellaneous disease,indicating that many internal injuries miscellaneous diseases were closely related to external infection .Tonic medicines were rarely seen alone in classical consumptive disease treatment.[Conclusion]Practice has proven that deep learning and understanding of Yin-wei theory has great guiding significance for us to put knowledge in TCM classic theories into clinical practice .Yin-wei theory opens an important window to learn“Treatise on Febrile and Miscellaneous Diseases”and trains clinical thinking,which is worth further discussion.

ObjectiveTo observe the infection of continuous aspiration of subglottic secretion(CASS) for patients with ventilator associated pneumonia (VAP).MethodsOne hundred and fifty VAPpatients under mechanical ventilation whose basical information were recorded were divided into two groupsby random digits table method:control group(70 cases) and CASS group(80 cases).Conventional VAPprevention was taken in control group and CASS group,while CASS therapy was added to CASS group.ResultsSex,age,acute physiology and chronic health evaluation Ⅱ score,recent antibiotics usage,airpressure,time in ICU,hospital stay and mortality rate of two groups had no statistical significance(P ＞0.05 ).The time of ventilator treatment of CASS group was obviously shorter than that of control group [ (5.2 ±1.4) d vs.(7.8 ± 1.2) d,P =0.02 ],and VAP incidence was lower than that of control group [ 22.5％ (18/80)vs.32.9％(23/70),P =0.04 ].ConclusionCASS could reduce the incidence of VAP and short the time ofventilator treatment.
