Carboxysomes are extremely efficient microcompartments committed to CO2 fixation due to tailored CO2-concentrating mechanism (CCM). In cyanobacteria and some chemoautotrophs, carboxysomes as organelle-like microbodies encapsulate ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) and carbonic anhydrase (CA). Together with active inorganic carbon uptake transporters, carboxysomes accumulate HCO3(-) in the cytoplasm, leading to high efficiency of carbon fixation. Based on the elucidation of structures and functionalities, heterologous production of carboxysomes has been achieved so far. In fact, the genes encoding either vacant carboxysome shell or only interior components have been characterized. This review summarizes the discovery along with types, showcases molecular structures and roles of carboxysomes in CCM, and presents their broad applications in metabolic engineering.

Objective To evaluate laparoscopy assisted radio frequency ablation (LRFA) and percutaneous radiofrequency ablation ( PRFA ) for the treatment of hepatocellular carcinoma ( HCC ).Methods A total of 525 HCC patients were enrolled,including LRFA group of 78 cases with 106 tumor nodules,and PRFA group of 447 cases with 565 tumor nodules.Results ( 1 ) In LRFA group complete ablation rate was 97.17％ (103/106); in LRFA group complete ablation rate was 93.09％ (526/565)(x2 =2.523,P =0.112).(2)The 1,3,5 year overall survival rate was 96.15％,55.12％ and 38.46％in LRFA group and 93.73％,48.54％ and 31.54％ in PRFA group respectively ( x2 =0.699,1.151,1.447 ; P =0.403,0.283,0.229 ).The 1,3,5 year disease-free survival rate was 94.87％,43.58％ and 28.21％ in LRFA group and 93.73％,48.54％ and 31.54％ in PRFA group respectively (x2 =0.915,0.303,0.174; P=0.339,0.582,0.676).The average disease-free survival time was 22.25 months in LRFA group and 21.53 months in PRFA group respectively.(3)The serious complications was 0％ (0/78)in LRFA group and 1.34％ ( 6/447 ) in PRFA group respectively.( 4 ) Recurrence rate was 23.07％(18/78) in LRFA group,and 34.89％ (156/447) in PRFA group ( x2 =4.189,P =0.041 ).Conclusions The therapeutical effect of LRFA equals that of PRFA,while enjoying lower recurrence rate,no serious complications and higher treatment safety.

Objective To establish patient-experience based key indicators for quality of care.Methods Literature review,collection of proven surveys on patient experience and satisfaction,study of China's conditions,with demonstrations by experts team.Results A framework was built for patientexperience based key indicators on quality of care.Level-1 indicators within the framework are tangibility,reliability,responsiveness,assurance,care and continuity.There are 28 level-2 indicators and 83level-3 indicators.Conclusion Such key indicators are highly practical as the basis for developing the scale of patient experience.

For professional degree graduate students, we improved the clinical teaching of pe-diatric surgery, on the basis of traditional forms of practice teaching, combining application of longitu-dinal cross major pediatric surgical practice. We had the student tracking patients from outpatient ser-vice and by going through the process of after examination, treatment, follow-up, and summarizing. students learnt all characteristics of the disease, expended their knowledge and grasped the correct, novel clinical thinking of diagnosis and treatment. The implementation of these measures obtained sat-isfactory teaching effect.

Epilepsy is a common disorder of neurological system in children.Inborn errors of metabolism (IEMs) is one of an important etiology of epilepsy.Seizures may be the first and the major presenting feature of IEMs.IEMs are a relatively rare cause of epilepsy,but their recognition and diagnosis is very important because several disorders are treatable.This review will concentrate on diseases where epilepsy is the predominant clinical manifestation and especially where the disease course can be positively influenced by specific metabolic therapies.

OBJECTIVE:To investigate the application of vancomycin in pediatric patients.METHODS:By reviewing medical histories of 368 pediatric patients who had been treated with vancomycin from 2005 to 2006,the use of vancomycin was investigated in respect of children' general condition,microbiological examination,dosage regimen,adverse drug reactions to evaluate the rationality of drug use.RESULTS:ADR occurred in 17 cases(4.6%).The use of vancomycin was rational or basically rational in 240 cases(65.2%).CONCLUSION:It is necessary to tighten more strict control on the use of vancomycin in pediatric patients.

Objective To investigate the correlation between the severity of coronary artery disease with se-rum bilirubin and left ventricular cardiac function. Methods Two hundred and six patients underwent blood bio-chemical ,color-echocardiography and angiography of coronary artery. The patients were divided into 4 ordinal groups according to the Gensini score indicating the severity of coronary artery disease. Results There were significant differences in total bilirubin(TBIL), left atrial dimension (LAD), left ventricular dimension (LVD) and left ventric-ular ejection fraction (LVEF) between the four groups(P<0.05 or P<0.01). The Spearman correlation coefficent between Gensini's scores and LAD, LVD were 0.280 (P=0.000) and 0.176 (P=0.011), respectively. The Spearman correlation coefficient between Gemini's scores and TBIL, LVEF were -0.541 (P<0.000) and -0.222 (P=0.001), respectively. The multiple linear regression between the Gensini's score and parameters showed that TBIL and LVD were independently correlated with the Gensini scores (P=0.000 and P=0.002, respec-tively). Conclusions TBIL and LVD were independently correlated with Gensini's score. LVEF was negatively cor-related with the severity of coronary disease and is a useful predictor for the severity of coronary atherosclerotic heart disease.

Objective To examine the impact of note-taking habits on academic scores of junior middle school students.Methods A sample of 412 junior middle school students were applied a self-developed note-taking habits inventory (NTHI) ,and the impact of note-taking habits on academic scores was examined by using bivariate correlation and linear regression analysis.Results Girls got significantly higher NTHI scores than boys [(3.67±0.55)vs(3.19±0.80),P＜0.01] ,and students from key classes got significantly higher NTHI scores than those of typical classes[(3.56±0.64)vs (3.37±0.75),P＜ 0.05].Total academic scores of Chinese,mathmatics and English was found significantly and positively related to total NTHI scores and the five subscales(r=0.280,P＜0.01 ;r=0.293,P＜ 0.01 ;r=0.126,P＜0.05 ;r=0.255,P＜0.01 ;r=0.239,P＜0.01 ;r=0.280,P ＜ 0.01).Attitude towards note-taking,full note-making and immediate note-rewriting showed direct and significant influence on total academic score of Chinese,mathmatics and English.Full note-making,attitude towards notetaking and immediate note-rewriting showed direct and significant influence on score of Chinese.So did of active note-making,immediate note-rewriting,full note-making and attitude towards note-taking on mathmatice scores,attitude towards note-taking and full note-making on score of Chinese.Conclusion Note-taking habits could be direct predictor of their academic scores for junior middle school students.
