Chinese Journal of Biochemical Pharmaceutics 2017;37(4):329-332
Objective To investigate the effect of pidotimod combined with antiviral drugs on immunologic function and myocardial enzyme spectrum in children with infectious mononucleosis.Methods 94 cases of children with infectious mononucleosis selected in Wenzhou Children's hospital were randomly divided into control group and research group,47 cases in each group.The control group were given conventional antiviral treatment; On this basis,the research group were given pidotimod,2 weeks for one period of treatment.Before and after treatment,immune function,cell factors and myocardial enzyme spectrum were tested,the clinical symptoms,signs,the curative effect and complications were observed and compared.Results Compared with before treatment,after treatment,serum CD4+,CD4+/CD8+ IgA and IgG increased,CD8+ decreased,TNF alpha,IL-6,AST,LDH,CK,CK-MB decreased(P<0.05).Compared with the control group,in the research group,CD4+,CD4+/CD8+,IgA and IgG content is higher,CD8+ content is lower,the TNF alpha,IL-6,AST,LDH,CK,CK-MB content is lower(P<0.05).The time of antipyretic,angina fade,narrow lymph nodes,liver and spleen shrinks and length of hospital stay in the research group were shorter than that in the control group(P<0.05).The effective rate was 74.47%in the control group,lower than 91.49%of research group(P<0.05).Conclusion The curative is exact that pidotimod combined with antiviral drugs on the treatment of infectious mononucleosis.It could improve immune function,reduce myocardial enzyme spectrum and inflammation.

BACKGROUND:Development of new coronary thrombolytic agents is hot in the market. A new drug, mutated recombinant tissue-type plasminogen activator (rtPAm), is the product of mutation of tPA by changing binding loci with plasminogen activator inhibitor (PAI)-1 to reduce the degradation. In vitro test has demonstrated that the activity of rtPAm is much higher than rtPA in the absence of PAI. The present study is to observe the efficacy of mutated recombinant tissue-type plasminogen activator (rtPAm) in coronary thrombolytic therapy. METHODS:A total of 30 adult beagles were equally divided into 5 groups after thrombi:vehicle group, urokinase group, rtPAm low-dose group, rtPAm medium-dose group, and rtPAm high-dose group. Thrombolytic effect and myocardial infarction were observed after thrombolytic therapy. RESULTS:In the urokinase group, time to reperfusion was (15.8±3.8) minutes. TIMI 2 flow was demonstrated in 4 beagles, TIMI 3 flow in 2, and re-occlusion in 4 after 90 minutes respectively. In the low-dose rtPAm group, time to reperfusion was (15±4.5) minutes; TIMI 2 flow was demonstrated in 2 beagles, TIMI 3 flow in 4, and re-occlusion in 2 after 90 minutes. In the high-dose rtPAm group, time to reperfusion was (7.5±2.6) minutes. None of the beagles showed re-occlusion after 90 minutes. The infarction areas were (2.1+0.9)% in the medium-dose rtPAm group and (0.7+0.4)% in the high-dose rtPAm group, which decreased significantly than those in the low-dose rtPAm group. The aggregation rate in the medium-dose and high-dose rtPAm groups decreased significantly than that in the urokinase group. CONCLUSION:rtPAm may serve as a thrombolytic agent with platelet-targeted fibrinolysis and antiplatelet aggregation activities.

Objective To investigate the effects of 15-deoxy-?12,14-prostaglandin J2(15d-PGJ2) and DDP on the growth of human pulmonary carcinoma PLA-801D cells and the mechanisms of apoptosis.Methods The human pulmonary carcinoma PLA-801D cells were selected and added to each well of 96-well place and cultivated for 24 h.Then the cells were treated with different concentrations of 15d-PGJ2(0,5,10,20,40 and 80 ?g?L-1) or 15d-PGJ2 combined with DDP(3 mg?L) for 24 h.0 ?g?L-1 15d-PGJ2 group was control group.The morphological changes of cells were observed under inverted microscope.Microculture tetrazolium(MTT)dye was applied to detect the proliferation of the human pulmonary carcinoma PLA-801D cells treated with 15d-PGJ2 and DDP.Diphenylamine assay(DPA) was used to evaluate the activation.Flow cytometry assay(FCM) was used to detect the apoptosis proportion and the changes of cell cycle.Results When the human pulmonary carcinoma PLA-801D cells were treated with low-concentration 15d-PGJ2 alone(5,10 and 20 ?g?L-1),no significant difference was observed in the inhibitory rate of cell growth and the apoptotic indexes such as the apoptosis proportion,the percent of DNA fragmentation and the activity of caspase-3 compared with control group(P

The training of airway management plays a vital role in standardized residency training plan during the rotation in the department of anesthesiology.Problem based-learning and airway simulation practice should be applied step by step based on the different requirements of standardized residency training plan.The training should be started from mask ventilation to endotracheal intubation,meanwhile clinical thinking ability and teamwork ability should be cultivated for the residents so that they can master the technique of airway management skillfully whenever and wherever.

To explore the measures of nursing management in the treatment of large number of infants with urinary calculi. The nursing management measures included launching the preparedness and response project for sudden public health events, formulating scientific and standardized nursing management system,optimizing work flow,strengthening nurse training,focusing on the details in nursing management,implementing disinfection and isolation system seriously,and paying close attention to health education for the parents of minority infants. Scientific nursing management can ensure the treatment effectiveness and nursing safety for the infants with urinary calculi.

Objective To investigate the effect and mechanism of combined therapy using anti-CTLA-4 antibody and doxoru-bicin on mice bearing breast cancer.Methods Balb/c mice inoculated with 4T-1 mouse breast cancer cell were used as tumor mod-els,which were randomly divided into blank group,solvent control group,anti-CTLA-4 antibody only group,doxorubicin only group and combined therapy group.Tumor growth of mice was observed.The ratio of spleen and bone marrow cell subgroup were evaluated.Tumor microenvironment apoptosis and microvessel density (MVD)were evaluated.Results The tumor volume of an-ti-CTLA-4 antibody only group,doxorubicin only group and combined therapy group were lower than those in the rest groups(P <0.05).The tumor volume and mass of combined therapy group was significantly higher than those of anti-CTLA-4 antibody only group,doxorubicin only group (P <0.05).Compared with blank group,solvent control group,CD8 + Tand CD4 + T ratio in anti-CTLA-4 antibody only group,doxorubicin only group,combined therapy group increased with significant difference (P <0.05). The positive cell apoptosis rate of combined therapy group was significantly higher than those of other groups(P < 0.05 ).The MVD of combined therapy group was significantly lower than those of other groups(P <0.05).The positive cell apoptosis rate and MVD of anti-CTLA-4 antibody only group,doxorubicin only group were better than those of blank group,solvent control group. Conclusion Combined therapy using anti-CTLA-4 antibody and doxorubicin could improve the immune,significantly inhibit the growth of tumor,promote cancer cell apoptosis and decrease MVD.
