OBJECTIVE To investigate the qacE△1-sul1 genes in multidrug-resistant Gram-negative bacilli and their significance.METHODS A total of 225 strains of multidrug-resistant Gram-negative bacilli were clinically isolated.The genes of qacE△1-sul1 were analyzed using polymerase chain reaction(PCR).RESULTS From them 120 strains of multidrug-resistant Gram-negative bacilli were found the qacE△1-sul1 genes.The positive rate of qacE△1-sul1 was 53.3%.CONCLUSIONS There are high percentages of qacE△1-sul1 genes in multidrug-resistant Gram-negative bacilli.

Objective To study the foxml gene and its protective effect on the lung tissue of rats with acute lung injury (ALI) induced by lipopolysaccharide (LPS), and to observe the dexamethason' s (DEX) impacts on foxml gene and the prognosis of ALI. Method Seventy-two healthy mice were randomly(random number) divid-ed into three groups: control group (A group, n = 24), model group (B group, n = 24) and DEX treatment group (C group, n = 24). The observing intervals were respectively set in 24 h, 48 h and 72 hours. At each ob-serving interval, the foxml protein in lung tissue of mice was detected by using immunohistochemistry (IHC), and the expression of foxml gene in lung tissue was detected by using RT-PCR, as well as to observe the pathological changes in lung tissue. Results Comparisons were made between paired groups at 24 h,48 h and 72 h intervals in which the expression of foxml mRNA and the level of foxml protein in lung tissue of mice in C group were signifi-cantly higher than those in B group (P < 0.05), and those in B group were significantly higher than those in A group (P < 0.05). The expression of foxml mRNA and the level of foxml protein in lung tissue of mice in B group at 48 h interval were significantly higher than those both at intervals of 72 h and 24 h (P < 0.05), and the those at 72 interval were significantly higher than those at 24 h interval (P < 0.05). Compared with B group, the pathologi-cal changes in lung tissue of mice in C group were lessened. Conclusions In both model group and dexamethasone treatment group, the expression of foxml mRNA and the level of foxml protein in lung tissue of mice are increased significantly. Dexamethasone lessens the injury of both vascular endothelial cells and alveolar epithelial ceils of lung tissue, and it also significantly increases the expression of foxml mRNA and the level of foxml protein.

Objective To investigate the diagnosis value of immunophenotype and karyotypes in newly diagnosed chronic lymphocytic leukemia (CLL).Methods To retrospect the flow cytometry (FCM) immunophenotype and karyotypes characteristics in newly diagnosed 70 CLL cases.Results In all cases,the positive rates of CD19,CD20,CD5,CD23,CD22 were 100 %,88.5 % (54/61),77.1% (54/70),67.6 % (23/34)and 51.9 % (27/52),respectively.And 6 were misdiagnosed,2 was CD+5CD+19(+),but CD20,CD22 were strongly positive,final diagnosed as mantle cell lymphoma (MCL) by FISH t(11;14) examination and CyclinDl; CD+5CD+19(-) CLL were 16 cases (22.9 %),but 4 were misdiagnosed,the misdiagnosis rate was 25 %,significantly higher than that of CD+5CD+19(-) CLL (P =0.030).59 cases were examined by conventional cytogcnetic (CC),and 13 cases were with abnormal karyotypes,positive rate was 22.0 %,with complex karyotypes in 5 cases (8.5 %); 10 cases combined with FISH abnormalities karyotype examination rate was 60 %.Conclusion Typical CLL immunophenotypic characteristics were CD5,CD19,CD23 co-expression,and CD-5 CLL with higher misdiagnosis rate,combined with CD20 (,) CD22 expression and karyotype analysis helps to CLL and other B lymphoid proliferative diseases (B-LPD) identification.Conventional cytogenetic detection combined with FISH scan can improve the recognition ability of abnormal chromosome.

Targeting such setbacks as difficulty to registerand difficulty to see doctors at outpatient clinic services,the hospital adopted the lean management since August 2010.For example,diversified reengineering of the outpatient service process in place,which has improved outpatient traffic at the registration section by means of innovated appointment mode and outpatients total reservation;workload balance by means of through-counters for registration and fee payment as well as the timeinterval outpatient visits to doctors; reduced human costs and outpatient back-forth movement by means of integrated service and resources integration.Lean management plays a positive role in hospital management,as proven by much shortened outpatient waiting time,much higher outpatient satisfaction,for a win-win of both patients and the hospital.

ObjectiveTo understand the concentration of heavy metal cadmium and cadmium in portunus and mantis shrimp, and to timely identify food safety problems and potential hazards. MethodsPortunus and mantis shrimp samples from different provinces were collected and categorized based on different regions and locations, and some samples were made from tissue parts. Graphite furnace atomic absorption spectrometry was used to detect cadmium items, the cadmium exposure of portunus and mantis shrimp was evaluated simultaneously ResultsThe detection rate of cadmium in 124 batches of portunus sold in Shanghai was 100% (124/124), the detection rate of cadmium in 63 batches of mantis shrimp sold in the market was also 100% (63/63). The cadmium content varied in different tissue parts, and the cadmium enrichment in hepatopancreas was the highest in the edible parts of portunus and mantis shrimp. The average detection value, 50th percentile value, 95th percentile value of cadmium in the hepatopancreas of portunus accounted for 52.64%, 49.28% and 98.65% of the PTMI, respectively. The average detection value, 50th percentile value and 95th percentile value of cadmium in the hepatopancreas of mantis shrimp accounted for 30.76%, 32.04% and 46.16% of the PTMI, respectively. ConclusionThe average residual levels of heavy metal cadmium in portunus and mantis shrimp are within the safe range.
