Objective To type Streptococcus pneumoniae(S.pneumoniae) isolated from children, and provide scientific basis for the correct selection of S.pneumoniae vaccine.Methods 182 strains of S.pneumoniae were collected from Children's Hospital of Hebei Province in 2014, species of strains were identified by polymerase chain reaction (PCR), types of strains were analyzed with multiplex PCR.Results PCR detection showed that cpsA gene amplification of 182 strains were all positive;multiplex PCR detection revealed that except 8 strains were not typed, the main types of the remaining 174 strains were 19 F (n=68, 37.36%), 19A(n=33, 18.13%), and 6A/6B (n=26,14.28%), the other types were 35B, 14, 6C/6D, 23F, 15B/15C, and so on.Conclusion The main types of 182 strains of S.pneumoniae are 19 F, 19A, and 6A/6B, which provide scientific basis for the correct selection of S.pneumoniae vaccine for this province.

Objective To formulate and standardized the procedure of bowl preparation before transrectal ultrasound-guided prostate biopsy. Methods The standardized transrectal ultrasound-guided prostate biopsy flowchart were formulated based on the best evidences and recommendations. One hundred and forty patients selected with suspected of prostate cancer and scheduled for transrectal ultrasound-guided prostate biopsy was equally assigned to two groups, the control group was given routine hospital practice before biopsy, and the observation group followed the formulated flowchart. Monitoring two groups for complications, time cost for bowl preparation, medical billing and the average day of hospitalization. Results The incidence of complications and the number of hospitalization days between two groups were comparable, the observation group in bowl preparation time was (3.75 ± 0.78) min, the control group in bowl preparation time was (11.88 ± 1.93) min, the difference of two groups showed statistical significance (t=15.643, P<0.01). The observation group in medical bill was￥(81.62±15.62), the control group in medical bill was ￥(427.78 ± 76.87), the difference of two groups showed statistical significance (t=-36.964, P<0.01). Conclusions Application of evidence-based practice to formalize bowl preparation and antibiotic use in transrectal ultrasound-guided prostate biopsy patient can facilitate the clinical nurses to provide homogenized care to prostate biopsy patients as well as improve the efficiency of nursing work.
