Objective To study the incidence rate and risk factors of catheter-related infection (CRI) in preemie with peripherally inserted central catheter (PICC),in order to facilitate the implementation of control strategies and control infection.Methods Two hundred and fifty-eight PICC preemie of birth weight less than 2.5 kg,according to whether the incidence of CRI were divided into CRI group and non CRI group,two groups of gestational age,birth weight,PICC time,parenteral nutrition time and PICC parenteral nutrition time were statistically analyzed and compared different indwelling time of CRI incidence.Results Diagnosis of CRI in 24 cases,the occurrence rate of 9.3% (24/258).There were significant differences in gestational age,birth weight,PICC time,parenteral nutrition time,PICC parenteral nutrition time between CRI group aad non CRI group (29.5 weeks vs.33.0 weeks,1.4 kg vs.1.8 kg,31.5 days vs.14.6 days,40.1 days vs.16.7 days,28.8 days vs.13.4 days,P < 0.01 or < 0.05).There was significant difference in incidence rate of CRI among different indwelling time (P < 0.01).The risk factors of CRI including gestational age (P =0.007),birth weight (P=0.000),PICC time (P=0.001),parenteral nutrition time (P=0.035),PICC parenteral nutrition time (P =0.001).Multivariate Logistic regression analysis showed the greatest impact on the 3 factors were birth weight,parenteral nutrition time,gestational age.Conclusion Gestational age,birth weight,PICC time,parenteral nutrition time are the risk factors of CRI in preemie with PICC.

OBJECTIVE:To optimize the extraction technology and forming technology of Compound Potentilla discolor gran-ules. METHODS:The extraction technology was optimized by single factor and orthogonal test with the amount of added water, soaking time,decocting time and decocting times as factors using the comprehensive score of the content of kaempferol,quercetin, and total flavonoids as indexes. Validation test was conducted. The type and ratio of excipients in forming technology were opti-mized by single factor test using comprehensive score of molding rate,soluble rate,moisture absorption rate and angle of repose as indexes. RESULTS:The optimal extraction process was 14-fold water,soaking for 0.5 h,decocting for 3 times,1.0 h each time. The RSDs of kaempferol,quercetin and total flavonoids content in validation test were 1.77%,1.76% and 4.62%(n=5). The ex-cipients of forming technology was the mixture of dextrin and soluble starch (2:1);the molding rate,soluble rate,moisture ab-sorption rate and angle of repose were 94.02%,76%,26% and 25.02 °,respectively. CONCLUSIONS:The optimized extraction technology of Compound P. discolor granules is stable and feasible,and prepared granules have good formability and moisture resis-tance.
