Objective To investigate the corelationship between proton pump inhibitors (PPI) and the incidence of hospital-acquired pneumonia (HAP) in abdominal surgical patients. Methods A total of 283 cases admitted from 2010 to 2014 were divided into PPI group (n = 326) and HRA group (n = 92). In PPI group, patients were divided into omeprazole subgroup (subgroup A, n = 146), lansoprazole subgroup (subgroup B, n = 102) and pantoprazole subgroup (subgroup C, n = 78) by the types of PPI. In HRA group, patients were divided into famotidine subgroup (subgroup D, n = 58) and ranitidine subgroup (subgroup E, n=34) by the types of histamine-2 receptor antagonist (H2RA). The incidence of stress ulcer bleeding (SUB) and HAP were calculated, while mechanical ventilation period (MV), ICU stay and 28-day-mortality were compared. Results There were lower incidences of SUB and HAP, shorter MV and ICU stay and lower 28-day-mortality in PPI group than those in HRA group (P < 0.05). In three subgroups of PPI group, there were no significant difference on incidence rate of SUB and HAP, as well as MV, ICU stay and 28-day-mortality. Conclusion The incidence rates of SUB and HAP are lower by using PPI than H2RA in abdominal surgical patients, as well as MV, ICU stay and 28-day-mortality. Different types of PPI have no effect on the incidence rate of HAP in abdominal surgical patients.

Objective To study the effect and safety of controlled-release dinoprostone on the induced labor of late pregnancy . Methods 60 cases of late pregnancy puerpera were treated in our hospital from February 2014 to September 2015, and divided into the control group and the experimental group with reference to the stochastic indicator method, 30 cases in each group. The control group were given induced labor by oxytocin, and the experimental group were given induced labor by controlled-release dinoprostone, Changes of Bishop score, effects of promoting cervical mature, induced labor situation, and adverse reaction were compared between two groups. Results After medication, the cervical Bishop score of the group (8.35±0.93) points were significantly higher than (6.64±0.72) of the control group (P<0.05). The total effective rate 96.67％(29/30) of promoting cervical mature in the experimental group was significantly higher than 80.00％ (24/30) of the control group (P<0.05). Medicine to clinical time (14.89±1.57)h and total labor time (6.94±1.52) h of the experimental group were significantly better than (21.48±2.35) h and (9.30±1.31) h of the control group (P<0.05). The rate of delivery by vagina of the experimental group 83.33％ (25/30) was significantly higher than 60.00％ (18/30) of the control group (P<0.05). There was no different on adverse reaction rate between two groups. Conclusion There was good effects of Controlled-release dinoprostone on the induced labor of later pregnancy, with high rate of delivery by vagina and better safety.
