Objective To explore the influence of QCC on the infection of orthopedic aseptic operation and healthcare workers in the operating room. Methods A total of 170 patients undergoing orthopedic aseptic operation from January 2015 to June 2015 were chosen as QCC group and 164 patients from June 2014 to December 2014 as control group. The wound infection rate,increased rate of WBC and temper-ature,the responsibility,initiative,problem solving skills,self-confidence,harmony,cohesion of doctors and nurses between two groups were recorded. Results The wound infection rate(2. 4%), increased rate of WBC(2. 4%) and temperature(1. 2%) in QCC group were signifi-cantly lower than those of control group(5. 5%,9. 1%,6. 7%). Moreover,the responsibility(4. 6 ± 0. 6) point,initiative(4. 4 ± 0. 3) point, problem solving skills(4. 1 ± 0. 8) point,self-confidence(4. 3 ± 0. 7) point,harmony(4. 8 ± 0. 9) point and cohesion (4. 2 ± 0. 4) point of doctors and nurses in QCC group were significantly higher than those of control group[(2.9±0.7) point,(2.3±0.5) point,(2.5±0.5) point,(2. 8 ± 0. 6) point,(3. 1 ± 0. 4) point,(1. 8 ± 0. 3) point,respectively)]. Conclusion QCC could effectively reduce the infection rate of orthopedic aseptic operation,and improve the overall quality of the participants health care workers in the operating room.

Objective To discuss the practical effect of process reengineering in PICC reengineer-ing management. Methods PICC process was analyzed and the original unreasonable process was reengineered. The number of cases for tube insertion, success rate of paracentesis, incidence rate of compli-cations and patients satisfaction degree with nursing before and after implementing process reengineering were compared nsing χ2 test. Results After the promotion for clinical use of PICC, the numbers of cases for tube insertion, success rate of paracentesis and incidence rate of complication evidently decreased, pa-tients satisfaction degree increased greatly. Conclusions Process reengineering makes the PICC man-agement more standard, safe and highly effective.

Objective To prepare vardenafil hydrochloride orally disintegrating tablets and evaluate their quality. Methods The tablets were prepared by direct power compression method, using crosslinking povidone ( PVPP ) as disintegrants. The preparation method was optimized by response surface test using amount of PVPP, menthol and taste-masking agents as factors with disintegrating time and distance of bitterness as index. The results of taste of orally disintegrating tablets were determined by electronic tongue, comparing to the results of taste tests. At the same time, the properties of the tablets were evaluated using appearance, content uniformity, disintegrating time, et al. as index. Results The optimal formula was as follows:PVPP 13. 26%, menthol 0. 43%, taste-masking agent SGxj 1. 26%. The results on evaluation of electronic tongue were consistent with the results of taste tests. The quality of the prepared tablets was in line with standard. The disintegrating time was (22. 34 ± 0. 34 ) s. Conclusion The preparation technology of orally disintegrating tablets is simple, and controllable in quality.
