The service behavior of medical staff is influenced by the organizational environment and management mode of the hospital. That is to say, the organization and management determine the standardization and sustainability of a hospital's humanistic services, and organizational driving force is also an important factor for the staff to innovate their services. Organization and management of a hospital' s humanistic services is composed of three factors: service operation management, service elements management and service performance management. These factors ensure a hospital's humanistic services to achieve whole-staff-participation, sustainability and standardization.

OBJECTIVE:To investigate the effects and safety of rosuvastatin on blood lipid and thyroid nodules in elderly pa-tients with dyslipidemia. METHODS:70 elderly patients with dyslipidemia were selected and randomly divided into control group (33 cases) and treatment group (37 cases). Control group was treated with routine treatment as abstain from tobacco and drink, low fat diet,Aspirin enteric-coated tablets 100 mg at bed time;treatment group was additionally treated with Rosuvastatin calcium tablet 10 mg at bed time,on the basis of control group. Both groups received the treatment for consecutive 12 weeks. BMI,blood lipid and the size of thyroid nodules were compared between 2 groups before and after treatment,and the occurrence of ADR was also observed. RESULTS:There was no significant difference in BMI between 2 groups before and after treatment (P>0.05). There was no significant difference in blood lipid level and the size of thyroid nodules between 2 groups before and after treatment (P>0.05). The blood lipid level and the size of thyroid nodule of 2 groups were improved significantly after treatment,and the treatment group was significantly better than the control group,with statistical significance(P<0.05). 2 pationts of creatment suf-fered from the increase of ALT but recovered withont angtreatment. CONCLUSIONS:Rosuvastatin can significantly improve blood lipid and decrease thyroid nodules in elderly patients with dyslipidemia with good safety.

Objective To discuss the characteristics,diagnosis,mechanism and the prognosis of dilated cardiomyopathy (DCM) induced by accessory pathway (AP).Methods The clinical,electrophysiological and echocardiographic characteristics in four cases,who were diagnosed as AP-induced DCM in the Department of Pediatric Cardiology of Beijing Anzhen Hospital,Capital Medical University from Mar.2011 to Aug.2012,were analyzed before and after ablation.Results The electrocardiograms of the 4 patients all indicated type B ventricular preexcitation.The locations of the APs were the right-sided anteroseptum and the free wall.Dyschronous contractions between posterior wall of left ventricle and interventricular septum were demonstrated by M-Mode echo.The basal segments of the interventricular septum turned thin and moved similar to an aneurysm,with typical bulging during end-systole,which was observed in all cases by two-dimension echo.Dyschronous left ventricular contraction was shown by speckle tracing technique.All patients received successful radio frequency current ablations.Their physical activities and growth improved greatly in the 4 cases.The echocardiographic data demonstrated that their left ventricular contraction recovered to synchrony shortly after the ablation,left ventricular ejection fraction recovered to normal and left ventricular end diastolic diameter decreased to almost normal gradually during the follow-up.Conclusions Overt right-sided APs localized in anteroseptum or free wall may have adverse effects on ventricular wall motion and left ventricular function.They can even result in DCM.Dyssynchronous ventricular contraction induced by right-sided overt accessory pathway may be the vital mechanism.AP-induced DCM is an indication for ablation with good prognosis.

Objective To investigate the relation between the expression of Caspase recruitment domain-containing membrane-associated guanylate kinase protein 1 (CARMA1),clinicopathological features of gastrointestinal mucosa-associated lymphoid tissue (MALT) lymphoma,diffuse large B cell lymphoma (DLBCL),and Helicobacter pylori (H.pylori) infection.Methods From January 1999 to March 2011,34 patients with DLBCL and 20 patients with MALT lymphoma were selected,and at same period 21 cases with reactive hyperplasia of gastrointestinal lymphoid tissue were enrolled in as control.The expression of CARMA1,Ki-67 and cytotoxin-associated gene A (CagA) at protein level were examined by immunohistochemistry.The relative expression quantity of CARMA1 mRNA was detected by real-time polymerase chain reaction (PCR).The condition of H.pylori infection in 25 gastric lymphoma and 10 controls was detected by methylene boric acid and blue staining or semi-nested PCR.Chi-square test was used for counting data analysis,t test for measurement data.Multivariate COX regression analysis was implemented for survival analysis.Survival curve was drawn by Kaplan-Meier method and analyzed by Log-rank test.Results The relative expression quantity of CARMA1 mRNA of 28 patients with DLBLC (3.073±1.846) was higher than that of 14 patients with MALT lymphoma,and the difference was statistically significant (F 0.975,P＜ 0.05).The positive rate of CARMA1 expression at protein level of gastrointestinal lymphoma group (75.9 ％,41/54) was higher than that of control group (47.6％,10/21),and the difference was statistically significant (x2 =5.568,P＜0.05),and the positive rate of CARMA1 expression of MALT lymphoma group (11/20) was lower than that of DLBCL group (88.2％,30/34),and the difference was statistically significant (x2 =5.900,P＜0.05).Among 42 patients with gastrointestinal lymphoma who received surgery,the relative expression quantity of CARMA1 mRNA in cases with high proliferation (2.885±1.837) was higher than that in cases with low proliferation.The expression of CARMA1 mRNA in the cases at advanced stage of the disease (4.416± 1.010) was higher than that in cases at early stage,and the difference was statistically significant (F=3.317 and 2.972,both P＜0.05).Among 54 patients with gastrointestinal lymphoma,the positive rate of CARMA1 expression at protein level of patients with high proliferation (88.6％,31/35) was higher that that of patients with low proliferation (10/19),and the difference was statistically significant (x22 ＝ 6.847,P＜0.05).There were no significant differences in relative expression quantity of CARMA1 mRNA and the positive rate of CARMA1 expression at protein level between 11 gastric lymphoma patients without H.pylori infection and 14 gastric lymphoma patients with H.pylori infection (both P＞0.05).The positive rate of CARMA1 expression at protein level of CagA positive and CagA negative H.pylori infected gastric lymphoma patients was 11/11 and 2/3.The expression of CARMA1 at protein level was correlated with the prognosis of gastrointestinal lymphoma (RR＝4.160,P＜0.05).In the 29 cases of patients with gastrointestinal MALT lymphoma and 18 cases of patients with DLBCL who were followed up,the survival situation of gastrointestinal lymphoma patients with CARMA1 positive expression rate over 50％ was worse than that of patients with the rate less than 50％,and the difference was statistically significant (x2=5.383 and 4.028,both P＜0.05).Conclusions CARMA1 might be involved in the pathogenesis and progression of MALT and DLBCL; and it might be a related factor of poor prognosis.There was no correlation between the expression of CARMA1 and H.pylori infection in these two lymphomas.

OBJECTIVE To comprehend the main pathogens and their drug resistance of multiple organ dysfunction syndrome(MODS) patients in ICU.METHODS We retrospectively analyzed all the bacteria isolated from 40 MODS patients in ICU.RESULTS The number of bacteria strains isolated was 173,92 G-bacteria strains made up 53.18%,60 G+ bacteria strains made up 34.68%,and 21 fungi strains made up 12.14%.The top six were Staphylococcus aureus(23.70%,MRSA was 13.87%),Pseudomonas aeruginosa(14.45%),Acinetobacter baumannii(11.56%),Stenotrophomonas maltophilia(8.67%),Candida tropicalis(8.09%),and Enterococcus faecalis(7.51%).The susceptive rate of S.aureus and Enterococcus to vancomycin was all 100%,the susceptive rate of A.baumannii and Klebsiella pneumoniae to carbapenems was high.64% patients had the multiplicity of infection(MOI) which always linked with long period in ICU,respiratory failure and mechanical ventilation.CONCLUSIONS MODS patients have a high morbility of G+ bacteria,fungi and MOI,most pathogens show multi-resistance to commonly used antibiotics.Strengthening the monitoring of infection and reasonable using antibiotics should be taken.
