ABSTRACT
Objective To compare the effect of puncture needles with different diameter on percutaneous biopsy for transplant kidney under ultrasound guidance. Methods A total of 82 cases underwent percutaneous renal biopsy for transplant kidney under ultrasound guidance,and were divided into two groups based on the diameters of puncture needles, Group 18 G (n =31)and Group 16 G (n =51).The effect of biopsy and complications were compared between the two groups. Results Compared with Group18 G,Group16 G used less puncture needles and obtained more glomeruli (both P <0.01).The qualified rate of renal specimens in Group 16 G was significantly higher than that of Group 18 G(P <0.05). There was no significant difference in postoperative complications between the two groups (P >0.05 ).Further stratified comparison was conducted,and the results showed that complications of the two groups were not statistically significant in case of puncture with 2 needles or 3 needles (both P >0.05). Conclusions There is similar safety of 16 G puncture needle and 18 G puncture needle to perform renal biopsies under ultrasound guidance.Under the allowable condition of patients,16 G puncture needle is superior to 18 G puncture needle and realizes high quality of renal specimens.
ABSTRACT
AIM:To explore the role of sphingosine 1-phosphate (S1P) in the dysfunction of vascular endo-thelial cells exposed to high glucose.METHODS: In human aortic endothelial cells cultured under high-glucose ( 22 mmol/L glucose) medium, nitric oxide ( NO) level, polymorphonuclear neutrophil-endothelial cell adhesion rate, protein level of intercellular adhesion molecule-1 ( ICAM-1) , migration of endothelial cells and Akt/endothelial nitric oxide syn-thase ( eNOS) pathway activation were observed after S1P, sphingosine kinase-1 inhibitor and/or Akt inhibitor treatments. RESULTS:S1P decreased NO level, increased polymorphonuclear neutrophil adhesive rate, enhanced ICAM-1 protein level, and inhibited migration of endothelial cells and activation of Akt/eNOS pathway in endothelial cells cultured under high-glucose condition.Sphingosine kinase-1 inhibitor, which reduced S1P content, significantly improved the above endo-thelial cell function indexes and restored the activation of Akt/eNOS pathway.CONCLUSION: S1P promoted high glu-cose-induced dysfunction of endothelial cells probably by inhibiting the activation of Akt/eNOS signal pathway.Targeting S1P is expected to become one of potential treatment strategies to reduce endothelial cell dysfunction.
ABSTRACT
Objective To evaluate the expression of IL-6,TGF-β,matrix metalloproteinase-7 (MMP-7) in the peritoneal fluid of different stage of endometriosis (EMs) patients.Methods Peritoneal fluid samples from female without EMs (n =35) and 45 patients with EMs (36 cases with stage Ⅰ,Ⅱ;9 cases with stage Ⅲ,Ⅳ)were obtained for detectionof IL-6,TGF-β,MMP-7byELISA.Results TheconcentrationofIL-6,TGF-β,MMP-7 was (736.5 ± 526.6) ng/L,(936.5 ± 523.5)ng/L and (5.63 ± 1.98) μg/L in EMs patients,which were higher than those in control group (P ＜ 0.01).The concentration of IL-6,MMP-7 was (948.6 ± 485.4) ng/L,(8.69 ± 1.23) μg/L in stage Ⅲ,Ⅳgroup,and (453.6 ± 256.8) rng/L,(4.23 ± 1.08) μg/L in stage Ⅰ,Ⅱ group,there were significant differences between the two groups (P ＜ 0.05).The concentration of MMP-7 was positively correlated with IL-6(r =0.789,P ＜0.01),and was negatively correlated with TGF-β(r =-0.458,P ＜0.05).Conclusion IL-6,TGF-β,MMP-7 may play roles in microecology immune imbalance and the development of EMs.
ABSTRACT
OBJECTIVE To investigate the genes of disinfectant-sulfadiazine and antibiotic resistance of Escherichia coli strains in elderly wards.METHODS Polymerase chain reaction and dilution test were used to detect and analyze the disinfectant-sulfadizane drug resistance gene and drug resistance of the E.coli.RESULTS From 30 E.coli strains isolated from elderly patients,21 were detected carrying disinfectant-sulfadizine drug resistance genes,and the positive rate of qacE△1-sulⅠ was 70.0%.CONCLUSIONS The detection rate of disinfectant-sulfadiazine drug resistance gene from E.coli strains isolated from elderly patients,the bacteria detection rates are relatively high.Most of the isolates were resistant to commonly used antibiotics.It suggests that clinical drug-resistant strains may be resistant to disinfectants.This condition should be paid much attention by disinfection wotkers of our country.
