Objective To explore the clinical value of high-sensitivity C-reactive protein(hsCRP) in chronic kidney disease(CKD) and the relationship between hsCRP and the different stages of CKD in children.Methods This study population consisted of patients who was diagnosised as CKD in Beijing Children′s Hospital from Mar.2007 to Feb.2008.The total number of subjects was 62 patients with 35 male and 27 female,the mean age was(8.7?4.0)years old,the course was from 3 months to 10 years.The healthy control group contains 30 healthy children with 16 male and 14 female,the mean age was(7.8?3.2) years old.The serum levels of hsCRP,creatine and ?2-microglobulin(?2-MG) were determined.The glomerular filtration rate(GFR) was caculated.The relationship between serum levels of hsCRP and ?2-MG,blood pressure as well as the renal function in these patients with CKD,stratified according to GFR were evaluated.The relationship between hsCRP and the blood pressure was evaluated.The statistical analysis for the data was done with SPSS 12.0 software.Use the t-test,order and examination and correlation analysis,P

Objective To investgate role of TLR2 in the activation, the innate immune and inflammation of human platelets. Methods Human washed platelets were separated from healthy people(n=5) and were stimulated with different concentrations(1μg/ml, 5μg/ml, 10μg/ml) of TLR2 agonistPam3CSK4(a synthetic bacterial lipoproteins). Then the platelet aggregation rate, the expression of CD62p and TLR2 on the platelet surface were measured. Results The platelet aggregation rate were (28.32±5.67)%, (52.56±8.54)% and (76.24±11.23)%, respectively, at concentration of 1μg/ml, 5μg/mland 10μg/ml of Pam3CSK4, more than (12.83±2.43)% at 0μg/ml of it. In addition, the expression of CD62p were (18.45±2.66)%, (22.45±2.04)%, (29.53±4.08)%, respectively at above concentration of Pam3 CSK4, more than (11.20±1.67)% of CD62p at control group(P<0.01). The expression of TLR2 was not significantly increased at a lower concentration of Pam3CSK4(1μg/ml) with (16.85±6.10)% compared with(10.81±3.99)% at the control group. However, it were (21.15±9.90)% and (22.52±9.26)%, respectively, at a higher concentration(5μg/ml, 10μg/ml)more than(10.81±3.99)% at the control group(P<0.05). Conclusion Pam3CSK4 induce aggregation, activation and the up-regulation of TLR2 of platelet by stimulating TLR2 receptor of it. Thereafter, TLR2 play an important role in the innate immune of platelet.

BACKGROUND: It has been proved that interleukin-18 (IL-18) involves in the development of acute cerebral infarction (ACI) and is positively correlated with the time of brain stroke onset, erythrocyte sedimentation rate (ESR), as well as neurological deficit and low-density value of brain CT.OBJECTIVE: To investigate the dynamic changes of serum IL-18 in the course of ACI.DESIGN: Verification analysis with patients as subjects and healthy volunteers as controls.SETTING: Department of neurology of a municipal hospital.PARTICIPANTS: Totally 46 inpatients (29 males and 17 females) with ACI were randomly selected from the Department of Neurology of People's Hospital, Maoming City, between December 2002 and January 2004.Meanwhile, 40 healthy controls (27 males and 13 females) were recruited from those who came to the hospital for routine physical examination. All the participants signed informed consent.METHODS: Fasting peripheral vein blood of 2 mL was collected from the patients on the 1st, 7rh, 14th and 21st days of ACI onset, and from healthy controls on the day of routine examination. The blood samples were centrifuged at 3 000 r/minute for 15 minutes at 4 ℃, and then the supernatant was collected for detecting IL-18 level by ELISA.MAIN OUTCOME MEASURES: The serum IL-18 level of patients on the 1st, 7th 14th and 21st days of ACI onset and that of healthy controls on the day of routine examination.RFSULTS: Totally 46 patients and 40 healthy controls were enrolled in this study and all data were statistically analyzed. The level of serum IL-18 was significantly higher in the patients with ACI than in normal controls on the 1st and 7th days of onset [(178±41) ng/L, (104±34) ng/L, (65±14) ng/L, P ＜ 0.01],but was similar on the 14th and 21st days [(88±36) ng/L, (72±33) ng/L,(65±14) ng/L, P＞ 0.05]. The level of serum IL-18 in ACI patients was significantly higher on the 1st day than on the 7th, 14th and 21 st days of the onset (P ＜ 0.05-0.01); moreover, it was also significantly higher on the 7th day than on the 21st day of the onset (P ＜ 0.05).CONCLUSION: The level of IL-18 increases obviously on the 1st day of ACI onset, and gradually decreases with the extended course of disease and time of treatment.

A comparative study on the glycolic acid oxidase (GO) of the domestic Spirulina(Arthrospira) platensis (S_(1)) from alkaline lake in Erdos Plateau and the imported S. (A.) platensis (S_(2)) and S. (A.) maxima (S_(3)) as well is made with colorimetric method. The results show that activity of GO (25℃, pH 8.0) of S_(1), S_(2 )and S_(3) is 70.9 U/gFW, 59.6 U/gFW and 80.9 U/gFW respectively; the GO's optimum temperature of S_(1)、S_(2) and S_(3 )is 30℃; the GO's optimum pH value of S_(1 )is 8.6,while that of S_(2 ) 8.2 and that of S_(3) 8.4; the GO of S_(1 )is stable from 0℃ to 35℃ and from pH 7.6 to pH 10.0, while that of S_(2) from 0℃ to 30℃ and from pH 8.0 to pH 9.0 and that of S_(3) from 0℃ to 35℃ and from pH 8.0 to pH 8.6. Adaptive range of S_(1) GO for temperature and pH is wider, and activity at low and high temperature and under strong acidand alkali conditions is higher than that of the imported species.

Objective To investigate the influence of Helicobacter pylori(Hp) infection on gastric mucin MUC5AC and MUC6 expression in children.Methods Sixty-six cases with gastric biopsy specimens were obtained from 66 children undergone gastroscopy from Jan.2005 to Jun.2006 for episodic or continuous abdominal pain,nausea,vomiting,abdominal distension,retching and dyspepsia,and so on.Among these children,39 cases were male and 27 cases were female,owning a average age(8.8?3.0)years.These specimens were divided into 2 groups followed by the presence of Hp,which was detected by rapid urease tests and Hp-PCR.Gastric mucin MUC5AC and MUC6 mRNA were also measured by reverse transcription PCR(RT-PCR),and Hematoxylin and Eosin staining were used for pathology observation.Comparisons between every groups were performed using t test and ?2 test,and statistical significance was defined as P
