Objective To explore the diagnosis,treatment and nursing of the patients complicated with pneumocystis carinii pneumonia (PCP) after renal transplantation,and to enhance the treatment effect of the disease.Methods The treatment and nursing processes of 37 patients complicated with PCP after renal transplantation in department of organ transplantation were retrospectively analyzed in the First Affiliated Hospital of China Medical University from May 1992 to July 2011.And the key points during nursing work were summarized.Results Of the total 37 patients,10 patients occurred respiratory failure,they were all treated by noninvasive ventilation,among which 6 patients were converted to tracheal intubation or tracheotomy mechanical ventilation.5 patients appeared rising serum creatinine(Scr) during treatment,but recovered to normal level after discontinuing SMZco for 1 week.4 patients died unfortunately,and the others were cured and discharged.Conclusions The occurrence of PCP after renal transplantation is closely related to the immune state of the patients,thus the priority of treatment for PCP should be prevention.Once happened,nursing care in aid is particularly important,then nurses should encourage patients to cooperate with treatment,relieve symptoms after infection,and promote recovery as well.

Objective To study the influence of valproate sodium(VPA)on neuroprotective effects of topiramate(TPM).Methods For-ty-eight 3-4 week-old male Wistar rats were randomly divided into 4 groups of 12 rats each.Group A was negative control rats,and groups B-D were rat model of epilepsy,induced by pentylenetetrazol(PTZ).The rats in 2 experimental groups were adminstered intragastrically with TPM 40 mg/kg and TPM 40 mg/kg+ VPA 200 mg/kg;2 control groups(groups A and B)with the equal amount of distilled water administration.After 2-month administration,changes of the behavior,levels of serum neuron-specific enolase(NSE)and the pathological in hippocampus were examined.Results The level of NSE in the group of TPM were significantly lower than that in masculine group,but no difference between masculine group and the TPM plus VPA.The pathological change in hippocampus were abatement in the group of TPM.Conclusion TPM plus high dosage of VPA will impaire the neuroprotective effects of TPM.

This study was designed to discover filovirus entry inhibitors in a drug library of commercial medicines. One thousand and six hundred drugs were screened using the ZEBOV-GP/HIV model, a pseudovirus formed by an HIV-core packed with the Zaire Ebola virus glycoprotein. We identified 12 gonadal hormone drugs with inhibitory activities in ZEBOV-GP/HIV entry at final concentration of 10 μmol x L(-1). Among them, three drugs exhibited strong activities with IC50 < 1 μmol x L(-1), such as toremifene citrate (IC50: 0.19 ± 0.02 μmol x L(-1)), tamoxifen citrate (IC50: 0.32 ± 0.01 μmol x L(-1)) and clomiphene citrate (IC50: 0.53 ± 0.02 μmol x L(-1)); seven drugs had moderate activities with IC50 between 1 and 10 μmol x L(-1), such as estradiol benzoate (IC50: 1.83 ± 5.69 μmol x L(-1)), raloxifene hydrochloride (IC50: 3.48 ± 0.07 μmol x L(-1)), equilin (IC50: 4.00 ± 9.94 μmol x L(-1)), estradiol (IC50: 5.26 ± 9.92 μmol x L(-1)), quinestrol (IC50: 6.36?5.37 gmol-L1), estrone (IC50: 6.87 ± 0.03 μmol-L1) and finasteride (IC50: 9.94 ± 0.45 μmol x L(-1)); two drugs, hexestrol (IC50: 14.20 ± 0.55 μmol x L(-1)) and chlormadinone acetate (IC50: 24.60 ± 0.36 μmol x L(-1)), had weak activities against ZEBOV. Further, toremifene citrate, tamoxifen citrate, clomiphene citrate, raloxifene hydrochloride and quinestrol could block both pseudovirus type Sudan ebola virus (SEBOV-GP/HIV) and Marburg virus (MARV-GP/HIV) entries.
