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 expression levels of 8 - hydroxy-deoxyguanosine (8-OHdG) in patients with different glucose metabolism and its relationship with islet dysfunction.Methods Based on the 75 g oral glucose tolerance test (OGTT), the patients were divided into 3 groups: normal glucose tolerance (NGT) group (30 patients), isolated impaired glucose tolerance (IGT) group (28 patients), type 2 diabetes mellitus (T2DM) group (28 patients), and 30 healthy subjects were selected as the healthy control group (healthy control, HC) . The triglyceride (TG) and total cholesterol (TC), glycosylated hemoglobin (HbA1c), fasting blood glucose (FBG), insulin resistance index, insulin and c-peptide area under the curve (AUC) were detected, and compared between groups, and the correlation between 8-OHdG and these indexes was analyzed. Results There was no difference in FBG values between NGT group and HC group, the indicators of patients in other groups were higher than HC group,the difference was statistically significant (P<0.01). The values of FBG, 8-OHdG, HbA1C and HOMA-IR of patients in IGT group were higher than NGT group, the difference was statistically significant (P<0.01) . The values of FBG ,8-OHdG, HbA1C and HOMA-IR in T2DM group were higher than IGT group. There were no differences in insulin AUC between NGT group, IGT group and T2DM group (P> 0.05) . 8-OHdG was correlated with FBG, HbA1c, HOMA-IR, C peptide AUC, insulin AUC, and the correlation coefficients were 0.704, 0.713, 0.665, 0.825 and 0.653, respectively, the differences were statistically significant. Conclusions 8-OHdG levels can reflect the status of islet dysfunction,and can be used as an indicator of islet function for diabetic patients.

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.

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 analyze the risk factors of respiratory tract infection by Stenotrophomonas maltophilia and its resistance to common antibiotics so as to guide clinical prevention and treatment.METHODS Thirty two patients of respiratory tract infection by S.maltophilia were examined.RESULTS Among them,the ratio of susceptivity of S.maltophilia to compound sulfamethoxazole was 87.5%,to levofloxacin was 78.1%,and to ticarcillin/clavulanic acid was 81.2%,but the ratio of resistance of S.maltophilia to imipenem was 100.0%,and it was also high to aminoglycosides and cephalosporins.CONCLUSIONS The old age,serious underlying diseases,many kinds of antibiotics used,infection in hospital and the use of glucocorticoids are the main risk factors of the respiratory tract infection by multiresistant S.maltophilia.

[Alstract] The harmonious dormitory interpersonal relationship of medical students will be of great significance to the development of college students' physical and mental,academic and construction of harmonious campus,medical environment.At present,there are four characteristics of building a harmonious medical students' dormitory interpersonal relationship:the atmosphere of dormitory culture construction is not strong,management and intervention system is not sound,the bodies of interpersonal relationship education are insufficient,and the degree of recognition is lower.The paper puts forward building the education model of one core,two wings,three combinations,the three culture as the core,university quality education and college vocational education as the two wings,combining themselves,parents,school,to provide a theoretical basis and practice guidance to establish a harmonious dormitory interpersonal relationship.

With the rapid development of critical care medicine (CCM) in China, there are increases in the number of intensive care units (ICUs), the scale of one center ICU and the team. Subspecialty construction of CCM is of great concerns for personnel training as well as discipline development, and is currently one of the urgent problems that need to be resolved. Experience of CCM subspecialty construction from Europe and the United States is lacking and it is necessary to propose some opinions on innovation to construct CCM subspecialties with Chinese characteristics. We believe that CCM sub-specialties construction should be based on the core knowledge (pathophysiology) and skill (organ monitoring and support). The following 7 sub-specialties can be set up: ① acute lung injury and mechanical ventilation; ② shock, hemodynamic monitoring and treatment; ③ acute kidney injury and blood purification; ④ sepsis and anti-infective therapy; ⑤ stress, sedation and analgesia; ⑥ nutrition and metabolic support; ⑦ coagulation, immune and inflammation. The core knowledge and skills of critical care medicine will constantly be updated and enriched. Therefore, sub-specialty settings should be constantly updated as well.
