Objective Pathogen and antimicrobial susceptibility in children with bacterial meningitis were reviewed.Methods The positive cultures of cerebrospinal fluid samples or blood samples and its antimicrobial susceptibility were analyzed in 401 patients with the clinical diagnosis of bacterial meningitis.Results 401 cases cerebrospinal fluid samples and blood samples submitted to microbiology laboratory, 97 cases (24%) were microscopically and culturally proven to be bacterial meningitis. The most frequent pathogen was staphylococcus aureus (28%), followed by the streptococcus pneumoniae (19%) and escherichia coli (13%). Pediococci as conditioned pathogen, were found in purulent meningitis patients. One of the isolates of Staphylococcus aureus was simultaneously resistant to both vancomycin and teicoplanin. Three isolates showed simultaneous resistance to imipenem/cilastatin.Conclusions Staphylococcus aureus as the predominant pathogens of pediatric ranks first among pediatric patients of purulent meningitis. Serious drug resistance of isolated pathogenic bacteria and its in antimicrobial susceptibility in the bacterial meningitis should be considered in clinical therapy.
3.Expression and antitumor activity of fusion protein RGD-TRAIL in Pichia pastoris.
Acta Pharmaceutica Sinica 2015;50(5):552-559
To compare the activity of RGD-TRAIL in different expression systems, RGD-TRAIL in both Escherichia coli (E.coli) and Pichia pastoris was constructed and expressed. In vitro activity of RGD-TRAIL from Pichia pastoris expression system was also analyzed. Genetic engineering techniques were used to construct recombinant plasmid pET30-rgd-trail and pHBM-rgd-trail. The recombinant protein RGD-TRAIL was purified with Ni ion affinity chromatography after induction. MTT assay, ELISA, scratch wound healing, transwell migration assay and Hoechst 33342 staining were performed to detect the effects of RGD-TRAIL on proliferation, binding activity, migration and apoptosis. The expression of apoptosis-associated proteins was detected by Western blotting. Recombinant protein RGD-TRAIL was successfully expressed in a form of inclusion body in E.coli, while expressed secretorily in Pichia pastoris. It possessed more potent cytotoxicity than RGD-TRAIL in E.coli by MTT assay. The RGD-TRAIL expressed by Pichia pastoris showed powerful binding affinity with cancer cells expressing α(v), DR4, DR5 and highly potent cytotoxicity through inducing apoptosis of cancer cells. Nuclear fragmentation was examined by Hoechst 33342 staining. Cleaved PARP and caspase-3 were also detected after incubation with RGD-TRAIL. Additionally, RGD-TRAIL inhibited migration significantly in A549 and HT1080 cells. The results demonstrate that Pichia pastoris expression system is more suitable for the recombinant protein RGD-TRAIL. Its binding affinity and antitumor activity might make RGD-TRAIL a promising candidate for cancer therapy.

Objective To compare the different micro inflammatory states between pafients undergone peritoneal dialysis and the pafients of chronic renal failure without dialysis,and to observe the condition of the occurrence of the micro inflammatory state in the peritoneal dialysis patients.Methods This study included 53 peritoneal dialysis patients who were followed-up in our dialysis center,34 chronic renal failure patients without dialysis and 47 normal controls,hs-CRP,IL-6,IL-8,TNF-? in venous blood were defected with empty stomach,and then compare the number of patients in each group.Results Patients'hs-CRP of the group of the PD is lower than that in the group of the chronic renal failure without dialysis,and higher than that in the normal people(P

ObjectiveTo investigate current iodine nutritional status of different groups of people in Harbin city, and to provide the basis for development of salt iodization standard and scientific iodine supplementation.MethodsThree urban districts and three surrounding counties were chosen in Harbin,2011.In each chosen urban district and county,one district office (township) was selected,and one residents committee (village) was chosen in each of the district office(township),and 30 households were selected by systematic sampling.Iodized salt,water iodine and iodine intake per capita were investigated.In each of the residents committee (village),20 adults aged 18 - 45,30 pregnant women or lactating women,and 100 school children aged 8 - 10 were selected.Urine samples were collected and urinary iodine level were tested.Salt iodine was determined by direct titration,water and urinary iodine by arsenic cerium catalytic spectrophotometry.Iodine uptake and iodine nutritional status of different populations in Harbin urban and rural areas were compared.ResultsThe edible rate of qunlified iodized salt were 93.3%(84/90) and 96.3%(156/162) in Harbin urban and rural residents,respectively,which were all greater than 90%,and the highest value of salt iodine were 38.3,46.0 mg/kg,respectively,in urban and rural areas,which all did not exceed the upper limit(50 mg/kg) of qualified iodized salt,but there were some samples of salt iodine content below the national standard(20 mg/kg).Water iodine value in urban and rural areas,even the highest value(9.40,8.40 μg/L),was failed to meet the national standard 10 μg/L; salt eaten by rural people perperson a day(8.33 g) was significantly higher than that of the urban people(7.03 g,Z=- 2.750,P < 0.01); in addition to rural children aged 8 - 10,whose urinary iodine value(228.6 μg/L) was higher,the values in urban and rural adults ( 111.3,195.6 μg/L),pregnant women ( 193.0,172.9 μg/L),lactating women ( 128.4,173.7 μg/L)and urban children ( 186.8 μg/L ) were all in appropriate level.The urinary iodine medians ( 195.6,228.6 μg/L )of adults and children in rural were significantly higher than that of urban adults and children(111.3,186.8 μg/L,Z =- 2.294,- 5.434,P < 0.05 or < 0.01,respectively).Population composition of iodine deficiency in both urban and rural adults,lactating and pregnant women[46.7%(28/60),21.6%(13/60) ; 21.1%(19/90),21.3% (18/89) ; 27.8% ( 25/90 ),42.2% (38/90) ] were significantly higher than that of the population composition with iodine excess[4.6%(4/60),5.0%(3/60) ; 16.7%(15/90),16.9%(15/89) ; 4.4%(4/90),0.0%(0/90)],but proportion of iodine excessive population in rural children [26.3%(79/300)] was significantly higher than proportion of iodine deficiency[5.6%(17/300)].ConclusionsThe natural environment of Harbin city is still in the iodinedeficient state.In addition to children in rural areas,the iodine intake and iodine nutrition level is basically appropriate; the risk of disease caused by iodine deficiency in adults,lactating and pregnant women is higher than by iodine excess,but the situation of children in rural is on the opposite.Therefore,we should strengthen the monitoring of different populations,and supplement iodine scientifically based on their need.
