ABSTRACT
Objective To study the change of regular semen parameters in infertile patients with simple low-pH semen before and after symptomatic treatment.Methods A total of 100 male infertility patients were recruited in the study,and were divided into two groups according to the pH range:patients group Ⅰ(n=40)and patients group Ⅱ(n=60);The two patients groups were tea-ted for low pH semen.When the first and second course of treatment were finished,semen pH values and conventional semen pa-rameters were tested and compared with those before treatment and control group.Results When the first course of treatment were finished,semen pH value of 75%(30/40)patients in group Ⅰ reached normal range,compared with the control group,the semen parameters were statistically different(P 0.05);Semen pH value of 90%(54/60)patients in group Ⅱ reached normal range,compared with the control group,the semen parameters and pH values were not statistically different(P >0.05 ). Conclusion The semen quality improved after the symptomatic treatment for low semen pH value and its an effective therapeutic approach for infertile patients with simple low-pH semen.
ABSTRACT
Objective To summarize clinical outcomes of interventional therapy on children with common congenital heart diseases(CHD).Methods A retrospective study was conducted.One hundred and fourteen patients with CHD were selected as our subjects,who underwent catheter interventional therapy in the Second Affiliated Hospital of Zhengzhou University from Jan.2004 and Dec.2012.The size of occluder was chose according to intraoperative echocardiography or cardiac imaging measurements,and occluder was released under assisted monitoring by subtraction angiography or cardiac ultrasound.Results There are all together 112 patients got the therapy successfully,2 cases failed(occluder detachment),and the success rate of operation was 98.2％.After the success of interventional,echocardiography examination showed that 11 cases were with star point across shunt,but the function of the around valve was not affected.One months after operation,echocardiography examination showed star point across shunt of 11 cases were disappeared,and no occluder was shifted as well as no thrombosis formed.Three months after operation,chest radiograph showed pulmonary congestion decreases and heart shadow was shrink.Thirty-eight cases were with three tricuspid regurgitation before operation and 32 cases were without reflux at 3 months after operation,and 6 cases relieved significantly.The patients were followed up for 6 months or 3 years,activity endurance was significantly improved than that before operation.No occluder was shiftand hemolysis and arrhythmia occurred.Meanwhile,No thrombosis or embolism occurred.Conclusion Interventional treatment for children with congenital heart disease is proved as a safe,effective methods and it have broad prospects in clinical application.
