Objective To investigate the infiltration of inflammatory cells and the pathogenesis of nasal polyps. Methods the nasal polyps were obtained from 42 patients undergoing nasal operations. The tissues from each patient were stained with HE and Toluidine Blue for eosiophils, lymphocyte, plasma cell and mast cell and observed under the light microscope. A mean number of the above cells were counted. All data were analyzed with the Ttest. Results Eosinophils were found predominantly in 12 polyps(28.57%). Lymphocyte infiltration was shown in the other 30 polyps (71.43%). Furthermore, many mast cells with only a few eosinophils were found in the lymphocyte infiltration polyps; the number of mast cells in these polyps were much more than those in eosinophil accumulation polyps with a very significant difference(P<0.01). Conclusion The accumulation of eosinophils in the nasal polyps does not appear to be related to the presence of mast cells and allergy. The disorder of immunity may play an important role in the formation of nasal polyps.

Objective To investigate the change of renal 1-alpha hydroxylase and its effect on bone mineral density in the old rats with type 2 diabetic nephropathy. Methods Forty Wistar rats of 18 months old were randomly divided into normal control (N), diabetes (D), diabetes treated with vitamin D_ 3 (T1) and diabetes treated with 1-?(OH)D_ 3 (T2) groups, respectively. Ten rats in each group. Dual energy X-ray absorption (DEXA) was used to determine bone mineral density (BMD) of lumbar spines and femoral bone. 24 h urinary protein excretion, serum 25(OH)D_ 3 and 1,25(OH)_ 2 D_ 3 were measured by radioimmunoassay. Results Compared with controls, 24 h urinary protein excretion increased remarkably D, T1, T2 groups, while BMD greatly decreased, much lower in D group and T1 group than T2 group (P0.05). The level of 1,25(OH)_ 2 D_ 3 in N group was the same to T2 group, but higher than D, T1 groups (P

Objective To explore the correlation between serum brain natriuretlc peptide(BNP) and cardiac function in children with pneumonia.Methods Fifty-two children with pneumonia were seleated.Among them 20 were complicated with congestive heart failure(CHF),including 9 boys and 11 girls,their ages ranging from 4 months to 4 years old;and 32 cases non-complicated with CHF,including 17 boys and 15 girls,their ages ranging from 5 months to 6 years old.Besides,there were 30 healthy children as control group,including 16 boys and 14 girls,their ages ranging from 6 months to 5 years old.For all the children,their serum BNP was measured by using ELISA met-hod,and CK-MB was measured by automatic biochemistry analyzer.In the sametime,their cardial function was measured by echocardiography.Results In the children with pneumonina complicated with CHF,the levels of serum BNP[(182.45?57.32) ng/L] and CK-MB [(48.19?16.08) IU/L] were higher than those of healthy control group[(35.12?13.84) ng/L,(11.48?4.29) IU/L Pa0.05).The levels of left ventricular ejection fraction(LVEF),left ventricle shortening fraction(FS),peak flow velocity of arteriae arota(PFVA),peak flow velocity of pulmonary artery(PFVP) in the children with pneumonia complicated with CHF were lower than those of healthy control group(Pa0.05).There was a positive correlation between the levels of serum BNP and CK-MB(r=0.28 P0.05).Conclusion The levels of serum BNP may be an important index in diagnosis of infant pneumonia complicated with CHF.

To evaluate the influence of phacoemulsification on corneal endothelium of senile cataract with lupus nephritis (LN).
●METHODS:This clinical trial involved 40 cataract patients with lupus nephritis (40 eyes), and 50 cases (50 eyes) without lupus nephritis. All of them underwent phacoemulsification+lOL implantation. The parameters of corneal endothelial cell including central corneal endothelium cell density ( CED ), average area of endothelial cell ( AVE) and coefficient of variation ( CV) were recorded by corneal endothelial microscope pre -operation and at one month after operation. The data were analyzed by SPSS 13. 0 statistical software.
● RESULTS: Both LN group and control group, the morphology of coneal endothelial was statistical significant differences between pre - operation and 1mo postoperation. The CED was lower, AVE and CV were higher ( P < 0. 05, respectively). A significant decrease in CED was seen in the LN group than did in the control group (P < 0. 05). Compared to control group,the post -operative AVE and CV in LN group was significantly increased (P<0. 05).
● CONCLUSlON: The corneal endothelial cell in lupus nephritis patients is more fragile. Safe and reliable operation should be selected for these patients.

Objective:To develop a biotin-streptavidin system (BAS)-mediated folate receptor (FR)-targeted quantum dot (QD) fluorescent probe and preliminarily validate the targeting ability and signal amplification effect of the probe. Methods: Streptavidin (SA) was covalently coupled with QD through the active ester method;the physical characteristics of the prepared QD-SA were veri-fied. Biotinylated folate was synthesized through the carrier bovine serum albumin using the same method and then reacted with QD-SA to form the special probe. The probe was used to identify SKOV3 cells and FR-negative A549 cells to verify its targeting speci-ficity. QD-SA was used as the contrast. SKOV3 cells were imaged using the BAS-mediated FR-targeted QD probe with a biotinylated folate incubation time of 1 or 4 h. Various reaction times were also tested between the probe and the QD-FA that was formed without BAS mediation. Results:The BAS-mediated FR-targeted QD probe specifically recognized FR-positive SKOV3 cells. The probe ob-tained higher fluorescent intensity after 4 h than after 1 h of biotinylated folate incubation. The BAS-mediated FR-targeted QD probe al-so had a stronger fluorescent signal than the QD-FA probe. Conclusion:The proposed probe presents a great potential in the early diag-nosis of ovarian cancer because of its high specificity and sensitivity.
