Chinese Journal of Microbiology and Immunology 2009;29(2):113-116
Objective To investigate the effect of killing the biofilm persisters by miconazole combined with two compound which can inhibit the drug efflux of C. albicans. Methods Lab reference strains of C. albicans YEM30(CAF2-1) formed the mature biofilm in the 96 well plates, and then treated with miconazole combined with Enniatin B (CDR1 inhibitor) and Milbemycins ot25 (CDRI/CDR2 inhibitor) respectively. After incubated for 48 hours by CFU counting on the YPD plates, the analysis of persisters with SAS8.0 software package for q test. Results Miconazole combined with drug efflux inhibitor can kill more persisters than miconazole alone(P <0.001), and combining with Enniatin B have a better results in eliminating the biofilm persisters than with Milbemycins α25. Conclusion Antifungal drugs combined with drug efflux pump inhibitors can kill more strains which can tolerate very high concentration of antifungal drugs. And searching the potential drug efflux pump inhibitors may be a new way for eliminating the persisters in biofilm, and consequently controlling the chronic recurrent fungal infectious diseases.

OBJECTIVE To probe how to avoid the complication after intravenous infusion for the elders. METHODS The cause of the complication in infusion therapy for the elders with a total of 80 cases in the past three years was analyzed retrospectively. RESULTS Among the complications after intravenous infusion for 80 elders,leakage injury accounted for 47 cases(58.5%), and phlebitis accounted for 21 cases(26.8%),respectively. CONCLUSIONS As the elders′ blood vessel wall is very thin,the intravenous infusion often causes injury,the nurses should pay more attention to operating of intravenous infusion for the elders,observing regularly,and prolonging the time for pressing the pinprick after pulling out the dropper,in order to reduce the coming of injury.

Objective To analyze the relationship between clinical features of infantile cough after infection and microelements in peripheral blood, and to observe the therapeutic of treating this cough with Milkvetch Root and Radix Glycyrrhizae. Methods 75 infantile patients were randomly recruited into a therapeutic group and a reference group. 39 patients in the therapeutic group were treated with Huangqi Zhusheye and Tablete Glycyrrhiza, while 36 patients in the reference group were treated with Azithromycin. The therapeutic effects were evaluated after the treatment. Meanwhile,microelements in peripheral blood of the 75 patients were assayed and made a contrast to 40 healthy children. Results The contents of Fe, Zn, and Mg in peripheral blood of the 75 patients dropped on different levels, comparing to the healthy children.The therapeutic effects of the therapeutic group was much better than the reference group with significant difference (P<0.05).Liver and renal functional lesion was unseen in both groups after the treatment. Conclusion Infantile past-infection cough may related with the decrease of Mg, Fe, and Zn. Combined usage of Milkvetch Root and Radix Glycyrrhizae clinically has good therapeutic effects to this disease.

Astemizole is nitrasoted with sodium nitrite in 0.12 mo l/L HAc solution at boiling bath for 25 min. The nitrosation product of astemizo le shows a reduction peak by single-sweep oscillopolarography. The peak potenti al is -0.72V (vs.Ag/AgCl). The first-order derivative peak current is propo rtional to the concentration of astemizole in the range of 4.0×10-7~1.6 ×10-5 mol/L (r=0.9997), with detection limit of 2.0×10-7 mol/L . The proposed method has been applied to the determination of astemizole in pha rmaceutical tablets.

AIM: To observe the changes in tumor-weight-inhibiting rates,immunological function,liver and renal function and the blood cell in the peripheral blood after administration of Shengmai Injection combined with chemotherapeutic agent,Oxaliplatin. METHODS: Hepatoma 22 tumor bearing mice models were established and then divided randomly into five groups,including control group,Oxaliplatin group,Shengmai Injection(high,middle and low dose) combined with Oxaliplatin groups.Each group had 10 mice.The five groups were injected introperitoneally with same amount of 5% glucose injection,Oxaliplatin 6 mg/kg and Shengmai Injection(14 mL/kg,7 mL/kg and 3.5 mL/kg) plus Oxaliplatin 6 mg/kg respectively,once a day for 14 days. After that,mice in the five groups were all killed after being anesthetized and the tumor-weight-inhibiting rates and the index of immunological function,liver and renal function and the blood cell in the peripheral blood were observed. RESULTS: (1) The tumor-weight-inhibiting rates were higher in each Shengmai Injection plus Oxaliplatin group than that in the Oxaliplatin group (P

Objective To study the expression and clinical significance of Survivin and PTEN in cervical carcinoma. Methods The expression of Survivin and PTEN in 60 cases of cervical carcinoma, 15 cases of CIN Ⅰ , 15 cases of CIN Ⅱ, 15 cases of CIN Ⅲ and 15 cases of normal cervical tissues were detected by immunohistochemical staining. Results The expression positive rates of Survivin were 86.67 %, 80.00 %,33.33 %, 20.00 % and 0, respectively, and those of PTEN were 21.67 %, 40.00 %, 80.00 %, 86.67 % and 100.00 % in cervical carcinoma, CIN Ⅲ, CIN Ⅱ, CIN Ⅰ and normal cervical tissues, respectively. The expression positive rates of Survivin were increased along with normal cervical epithelium, CIN Ⅰ, CIN Ⅱ,CIN Ⅲ and invasive carcinoma of cervix;while those of PTEN were inverse order.Compared with the expression positive rates of Survivin and PTEN protein in the CIN Ⅱ group, those in the CIN Ⅲ group had significant differences (P <0.01 and P <0.05, respectively). Expressions of Survivin and PTEN were correlated to the size of focus(P <0.05), the depth of tumor and pelvic lymphnode metastasis (P <0.05), but not to clinical staging, pathological types, pathological grading and age(P >0.05). There was a negative correlation between the expression of PTEN and Survivin in cervical carcinoma. Conclusion The expressions of Survivin and PTEN are correlated with invasion and metastasis of cervical carcinoma, and be related to clinical pathotology.Survivin and PTEN may play a important role in the formation, proliferation, differentuation and metastasis of cervical carcinoma. They may be used as markers of early diagnose, efficacy and prognosis evaluation.
