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 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.

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.

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.

Objective To summarize the sonographic features and the diagnostic value of transvaginal three dimensional OmniView sonography for congenital uterine malformation. Methods Thirty-six patients who were suspected as uterus septus on transvaginal two-dimensionalultrasound (2D US) were examined by transvaginal three dimensional ultrasound (3D US) of OmniView. The coronal plane images were acquired. The fundus,cavity and cervix of the uterus were analyzed. The depths of fundal cleft were measured.In comparison with the test results of hysterosalpingography (HSG), hysteroscopy, hysteroscopy combined with laparoscope or magnetic resonance imaging (MRI), the sonographic features and the diagnostic value of transvaginal three dimensional OmniView sonography were summarized. Results Among the 36 cases underwent transvaginal three-dimensional ultrasound (3D US), 16 cases were diagnosed as incomplete septate uterus, 5 cases as complete septate uterus, 5 cases as arcuate uterus, 4 cases as bicornuate uterus, 4 cases as gemini and 2 cases as unicornuate uterus. The results of all 36 cases were confirmed by surgery or magnetic resonance imaging (MRI). The sonographic features of transvaginal three dimensional OmniView sonography:(1) Twenty-one septate uterus had convexes (in 12 cases) or minimally depressed fundus (in 9 cases, depth of cleft ≤ 1.0 cm) and had Y-shaped (16 incomplete septate uterus without septum extending into cervix) or V-shaped cavity (5 complete septate uterus with septum extending into cervix). (2) Five arcuate uterus had an obtuse angle at the central point of septum. (3) Four bicornuate uterus had fundal depression more than 1.0 cm and were divided into two cornuas. (4) Four gemini had two complete uterus and cervix. (5) Two uterus unicornis had single endometrial and smaller than normal. Conclusions Transvaginal 3D OmniView sonopgraphy of uterine may display a good coronal plane, on which the relationship of the cavity and the fundus, the depth of fundal cleft and the angle at the central point of the septum can be well depicted and measured. It is a practical, reliable and noninvasive method, and superior to 2D US in the diagnostic classification of complex uterus malformation.
