Objective To study the effect of mental intervention on pregnant result in patients undergoing IVF-ET treatment.Methods 206 patients undergoing IVF-ET treatment in the hospital from February 2012 to Jan-uary 2013 were selected and randomly divided into two groups. The experiment group (n=103) was followed by mental intervention after the patients enrolled the IVF-ET treatment, the control group (n=103) enrolled the IVF-ET treatment without mental intervention.Results The HAMA and HAMD quantity grades for anxious and depression of patients in the experiment group were significantly lower than those of control ( <0.01), and the pregnancy rate of experiment group (45.63%) was higher than that of control (30.10%) <0.05. Conclusion Mental intervention for patients undergoing IVF-ET treatment could alleviate their anxiety-depression and improve the pregnancy rate of IVF.

Objective To investigate the efficacy and safety of leukoreduction therapy in severe per-tussis in infants. Methods Therapeutic processes of 3 cases of severe pertussis in PICU of Shanghai Children′s Medical Center were retrospectively studied from October 2017 to May 2018. We reviewed the related literatures and summarized the time and effectiveness of leukoreduction therapy in severe pertussis. Results All 3 cases had leukocytosis,respiratory faliure,pulmonary hypertension and right heart failure. One case had multiple organ failure before undergoing exchange transfusion therapy and eventually died. Two cases that had pulmonary hypertension during the period of WBC′s rising accepted leukopheresis therapy before multiple organ failure,and eventually survived. We reviewed the foreign literatures which was almost case reports,leukoreduction therapy might improve the prognosis of severe pertussis in infants,but the time of using it had no conclusion. Conclusion This is the first report of leukoreduction therapy for the severe per-tussis in infants in China. It provides a new method for the treatment of severe pertussis in infants. It is worth looking forward to use this method combined with continuous renal replacement therapy and extracorporeal membrane oxygenation technology. In the future,multicenter clinical research should be done to explore the effectiveness and safety of leukoreduction therapy in the severe pertussis in infants.
