Pseudomonas aeruginosa (PA) is a kind of opportunistic pathogen which can cause a wide range of serious infections clinically.These infections are often associated with the formation of biofilm, and are difficult to treat due to the complexity of mechanisms.Some studies have showed that genotype and phenotype of biofilm PA will change, and biofilm PA will aggregate together and secrete extracellular polymeric substance.Therefore, innate immune system could not recognize the camouflaged antigens.Besides, biofilm PA can secrete a variety of virulent factors to hamper the function of innate immune system.This article introduces the main chronic infection caused by PA biofilm and the relationship between biofilm PA and natural innate immune system.

Objectives:To investigate the association and the prognostic significance of the expression of telomerase activity (TA) and apoptosis (APO) in tissues of primary breast cancer.Methods:TRAP-PCR and ELISA were developed to detect the expression of TA,and make quantitative and qualitative analysis respectively.TUNEL was also used to evaluate apoptosis cells in cancer lesions and count apoptosis index (AI).The expression levels of proteins of oncogene Bcl-2 and p53 were measured by means of S-P immunohistochemistry.Results:The mean TA positive expression rate was 89.8%,and its mean optic density was (A) 0.63±0.29,which were significantly higher than those of normal tissues and benign breast lesions (P<0.05).The 5 years survival rate of patients with positive TA expression was lower (60.3%) than those of negative expression (77.4%).There were no relations between TA expression and patients ages,TNM staging,lymph nodes metastasis,size,locations and pathological types of cancer.But TA was positively correlated with APO (r=0.733 1,P<0.05) and the protein expression of oncogene Bcl-2 (r=0.781 4,P<0.05) and negatively correlated with that of p53 (r=-0.625 5,P<0.05).Moreover,in patients receiving preoperative chemotherapy,the levels of TA expression were much lower than those without chemotherapy (64.7% vs 85.1%),and the former had higher AI than the latter (7.19±3.75% vs 3.23±2.04%),intraarterial chemotherapy group were superior significantly to adjuvant group (P<0.05).Multivariate Cox Regression Analysis showed that only TA and AI influenced the survival time of primary breast cancer patients,and patients with higher positive TA expression and AI>4.0% had shorter survival time than those of negative TA expression and AI<4.0% patients.Conclusions:There was a significant correlation between TA and APO and its related oncogene Bcl-2,p53.TA and APO are of great diagnostic values,therapeutic helps and prognostic significance in the formation and the development of primary breast cancer.

Objective To explore the association of Toll-like receptor 4 TLR4 and lipopolysaccharide receptor CD14 gene polymorphisms with Kawasaki disease (KD) susceptibility.Methods Three-color fluorescent staining flow-cytometry was used to detect the expression of TLR4 in peripheral blood white blood cell of 76 KD children and 118 healthy control group.The gene of TLR4 (-896A/G), (-1196C/T) and CD14 (-260C/T) polymorphisms was identified by polymerase chain reaction-restriction fragment length polymorphisms; and the relationship between genotype and KD was analyzed.Results 1.The values of mean fluorescence intensity (MFI) of TLR4 in peripheral blood white blood cell of the KD groups and the healthy control groups were 2.87?0.96, 10.55?4.87, 23.36?8.28 and 3.26?0.65, 7.55?1.21, 25.41?6.97, respectively; There was a gradual increase of these values on lymphocyte, neutrophilic leukocyte and mononuclear cell in both groups.2.(-896A/G), (-1196C/T) polymorphisms of TLR4 gene were not found in both groups.3.The frequency of each genotype of CD14 gene (-260C/T) was 35.5%CC, 30.3%CT, 34.2%TT in KD group and 38.1%CC, 47.5%CT, 14.4%TT in healthy control group.The frequency of each genotype was significantly different in 2 groups(?2=11.62 P

Objective To evaluate the effect of percutaneous closure of patent ductus arteriosus(PDA)on left ventricular size and function by measuring plasma N-terminal brain natriuretic peptide(NT-proBNP)level and using two-dimensional echocardiography.Methods According to the modified Ross score,55 children with PDA were divided into 3 groups,no congestive heart failure(CHF)group(31 cases),mild CHF group(14 cases)and moderate-severe CHF group(10 cases).Fifteen age-matched and weight-matched normal children were used as controls.Plasma NT-proBNP was measured using enzyme-linked immunosorbent assay(ELISA).All patients had complete echocardiographic study,including measurement of left ventricular end diastolic volume index(LVEDVI),left ventricular end systolic volume index(LVESVI),and left ventricular ejection fraction(LVEF),and left ventricular fractional shortening(LVFS).The correlation between plasma NT-proBNP level and echocardiographic cardiac functional indexes was determined.Results 1.Before operation LVEDVI and LVESVI in PDA patients were obviously higher than those in normal controls(Pa0.05).3.Three months after operation plasma NT-proBNP level,LVEDVI and LVESVI were significantly decreased(P

OBJECTIVETo compare the therapeutic effects between close reduction and plaster slab fixation combined with plaster external traction and operation for the treatment of pediatric closed Gartland type III supracondylar humerus fractures without neurovascular injury complications.

METHODSFrom June 2009 to June 2012, 151 children with closed Gartland III supracondylar humerus fractures were retrospectively studied and divided into two groups, including 87 boys and 64 girls, ranging in age from 1 to 12 years old with an average of 5.3 years old. Among them, 76 children (conservative group) were treated with close reduction and plaster slab fixation combined with plaster external traction; 75 children (operation group) underwent surgical operation. The time of elbow joint function exercise, the healing time of fracture, the function recovery of elbow joint and carrying angle was recorded and analyzed. The therapeutic effects were evaluated by the Flynn criteria system.

RESULTSAll patients were followed up from 6 to 36 months (18.3 months on average). The average time of fracture healing and elbow joint functional exercise of the conservative group was shorter than those of operation group (P < 0.001). Motion range of the elbows and carrying angle of two groups were no statistical difference (P > 0.05). According to Flynn criteria system, in conservative group, the result was excellent in 31 cases, good in 35, fair in 7, and poor in 3; in operation group, 27 in excellent, 30 in good, 17 in fair and 1 in poor; there was no significant difference between two groups in therapeutic effects (P > 0.05).

CONCLUSIONClose reduction and plaster slab fixation combined with plaster external traction in treatment of pediatric closed Gartland type III supracondylar humerus fractures without neurovascular injury complications,which has similar effect to surgical treatment, and the time of fracture healing and elbow joint function exercise are significantly shorter.

Objective To investigate the efficacy and safety of a schedule of 2 cycles' high-dose dexamethasone (HD-DXM) as an initial therapy in adults immune thrombocytopenia (ITP), and compare with conventional dose prednisone therapy. Method A total of 59 newly diagnosed ITP patients were divided into 2 groups randomly. In 30 patients ( Dexamethasone group), oral HD-DXM was administered at 40 mg/d for 4 consecutive days, repeated one week later, and then failed to maintain. In the remaining 29and then gradually tapered. Results For short-term efficacy, after 1 and 2 weeks of treatment, the response rate in Dexamethasone group was significantly higher than that in Prednisone group (50. 0% vs 24. 1%, P ＜0. 01; 73.3% vs 55.2%, P ＜0. 05 ), while 3 weeks later, there was no remarkable difference between the two groups(83.3% vs 68.9%, P ＞ 0. 05 ), though the response rate in Dexamethasone group remained higher. For long-term effect, at the end of the 2nd and 3rd months of follow-up, the relapse rate in Dexamethasone group was significantly lower than that in Prednisone group(24. 0% vs 40. 0%, P ＜ 0. 05;32.0% vs 65. 0%, P ＜ 0. 01 ), while at the end of the 1st month of follow-up, there was no significant difference( 16. 0% vs 20. 0%, P ＞0.05 ). In addition, it's well tolerated and no complications such as severe infection or Cushing syndrome were complained in Dexamethasone group. Conclusion HD-DXM possesses an advantage over conventional dose prednisone therapy in efficacy and safety.
