Objective: To observe the therapeutic effect of nicorandil on microvascular angina pectoris (MAP). Methods: A total of 60 MAP patients were randomly divided into nicorandil group (n=30) and routine treatment group (n=30), and they were treated for 12 weeks. Onset times and duration of angina pectoris, changes of related parameters of ECG treadmill exercise test before and after treatment, and total effective rate were compared between two groups. Results: Compared with before treatment, there were significant reductions in onset times and duration of angina pectoris and maximum depression extent of ST segment (P<0.05 or <0.01) and significant increase in total exercise time (P<0.01) after treatment in both groups; compared with routine treatment group, there were significant reductions in onset times of angina pectoris [(10.3±1.6) times/week vs. (9.6±1.7) times/week] and maximum depression of ST segment [(0.8±0.3)mm vs. (0.6±0.2)mm], and significant increase in total exercise time [(7.8±1.4) min vs. (9.4±1.6) min] and total effective rate (73.3% vs. 93.3%) in nicorandil group, P<0.05 or <0.01. Conclusion: Nicorandil possesses significant therapeutic effect on microvascular angina pectoris, and it is worth further study.

Objective:To analyze the levels of immune cytokine in peripheral blood(PB) and the expressions of immune related transcription factors in placenta cytotrophoblast,which in patients with pregnancy-induced hypertension(PIH).And to explore the effect of fetal-maternal immune tolerance on pregnancy-induced hypertension.Methods:50 cases patients with PIH were selected as the observation group,and 40 healthy people were chosen as the control group.Enzyme-linked immunoassay(ELISA) was performed to detect the levels of IFN-γ,IL-4,IL-17 and TGF-β in peripheral blood.Quantitative Real-time PCR(RT-qPCR) and Western blot were used to analyze the mRNA expressions and protein levels of T-bet,GATA-3,RORC and Foxp3 in placenta cytotrophoblast,respectively.Results:①Compared with the control group,the IFN-γ and IL-17 levels in peripheral blood in the observation group were obviously higher and the TGF-β level was greatly lower(P<0.05).There was no significant difference of IL-4 level between the two groups(P>0.05),but the ratios of IFN-γ/ IL-4 and IL-17/TGF-β in the observation group were larger than that in the control group(P<0.05).②Compared with the control group,the mRNA expressios and protein levels of T-bet and RORC in the observation group were increased significantly(P<0.05),but that of GATA-3 and Foxp3 were decreased greatly(P<0.05).Thus,the ratios of T-bet/GATA-3 and RORC/Foxp3 in the observation group were significantly larger than that in the control group(P<0.05).Conclusion:PIH is occurred with the imbalance of Th1/Th2 and Th17/Treg,and it might be associated with the mechanism of fetal-maternal immune tolerance disorder that induced by Th cells.

Objective To summarize the nursing experience for three cases of above 1-month-oldinfants with total transposition of the great artery after Switch operation.Methods The vital signs of the infants were monitored,including the respiratory system,circulation system,temperature,urine quantity,feeding and delayed sternal closure.Appropriate measures were adopted to cope with changes in the above mentioned aspects.Results All the 3 infants were cured with good nursing effect.Conclusion Switch operation was a complicated operation.The 3 infants missed the-optimum operation time and left great difficulty for nursing.Close monitoring and delicate nursing proved to be the pivotal process to ensure the successful curement.

Objective To explore the mechanism of the interaction between sulfur dioxide(SO2) and bovine serum albumin (BSA). Methods The spectrum characteristic of the interaction between SO2 and BSA was studied by fluorescence quenching spectrum and three dimensional fluorescence spectrum. Results The binding constants and thermodynamic parameters of SO2 with BSA were calculated at different temperatures. The quenching mechanism of BSA by SO2 was determined,the result showed that it did not belong to dynamic quenching but belonged to static quenching,which produced the complex. The hydrophobic interaction and electrostatic force played a main role in the binding of SO2 with BSA and only about one binding site occurred in the reaction. There was a certain influence to the conformation of BSA after adding SO2. Conclusion The quenching reaction of BSA by SO2 was weak. SO2 dissolved in body fluid easily and then SO32-and HSO3-are generated in vivo.

Objective To study the psychological features of systemic lupus erythematosus (SLE) women who underwent pregnancy termination and to investigate the effects of nursing interference on their psychological state.Methods Psychological nursing and symptomatic nursing were performed in 12 patients.The psychological state was evaluated by Self Rating Anxiety Scale (SAS)and Self-rating Depression Scale (SDS) before and after the interference.Results SAS and SDS score were remarkably reduced after nursing interference.Conclusions Nursing interference can reduce the negative effects caused by psychological state,reduce their psychological pressure,increase compliance to medical orders and promote recovery.
