Objective To explore the usefulness of enhanced patient education in increasing the patients' knowledge and awareness of peripherally inserted central catheter (PICC) protection.Methods Totally 200 patients with PICC in Neijiang First People's Hospital from June 2009 to June 2012 were divided into control group (odd numbers,conventional patient education,n =100) and observation group (even numbers,enhanced patient education,n =100) according to their admission numbers.The patients' knowledge and awareness of PICC protection were analyzed after treatment,and the incidences of adverse events and catheter indwelling time were also compared between these two groups.Results Compared with the control group,the observation group had significantly higher PICC protection knowledge rate (91％ vs.78％,P =0.001),awarehess rate (95％ vs.80％,P=0.011),lower incidence of adverse events (1％ vs.5％,P =0.034),and longer PICC indwelling time [(125.8 ± 10.6) d vs.(106.7 ±8.2) d,P =0.026].Conclusion Enhanced patient education can effectively enhance the patients' knowledge and awareness of PICC protection.

Objective:To investigate the protective effects of quercetin ( QU) on myocardial ischemia/reperfusion ( MI/R) injury in rats and the underlying mechanisms. Methods:MI/R injury model in rats was prepared by coronary artery ligation for 30 min fol-lowed by 120 min reperfusion. And then the rats were randomly divided into 5 groups, QU (25, 50 and 100 mg·kg-1 ) groups, the model group and the sham group (n=10). QU was orally administered once a day for 7 days before the operation. The CK and LDH activities and TNF-α and IL-1β levels in serum were examined respectively by colorimetric and ELISA method after the reperfusion. Besides, the area of myocardial infarction was calculated and MPO activity in heart homogenate was detected. Results:QU (100 and 50 mg·kg-1 ) could significantly reduced the area of myocardial infarction to 25. 00% and 25. 31%, respectively, and compared with that of 32. 55% in the model group, the difference was significant (P<0. 05). The CK activity in the three QU groups was 779. 82, 793.90 and 870.86 U·L-1, respectively, which was significantly lower than that (1 123.78 U·L-1) in the model group (P<0. 01). The LDH activity in the three QU groups was 2 138. 21, 2 277. 40 and 2 416. 53 U·L-1, respectively, which was significant-ly lower than that (3 105.32 U·L-1) in the model group (P<0.05 or P<0.01). Compared with that (311.72 U·g-1) in the model group, the MPO activity in heart homogenate in the three QU groups was reduced to 185. 70, 190. 66 and 210. 03 U·g-1 , re-spectively (P<0. 05 or P<0. 01). Compared with that (119. 55 pg·ml-1) in the model group, QU (100 and 50 mg·kg-1) signif-icantly reduced the level of TNF-αto 97. 48 and 97. 54 pg·ml-1, respectively (P<0. 05). Compared with that (673. 34 pg·ml-1) in the model group, IL-1βlevel in serum in the three QU groups was evidently reduced to 419. 26, 438. 72 and 492. 53 pg·ml-1 , re-spectively (P<0. 01). Conclusion:The effectiveness of QU pretreatment in MI/R injury appears to be associated with the inhibition of neutrophil infiltration and expression of inflammatory cytokines.

Objective:To evaluate the clinical effects of Distal-Jet appliance on the distalization of maxillary molar.Methods:12 Class Ⅱ malocclusion patients(at the average age of 12.3 years) with mesially moved maxillary molar were treated by Distal-Jet appliance. Cephalometic radiographs and dental models were taken and analyzed before and after molar distalization.Results:The treatment time was (4.3?2.8) months. After treatment following effects were achieved:①The maxillary molar was distalized by (3.6?0.75) mm per side with crown tilting distally by ( 3.5 ?3)?. ②The first premolar was moved mesially by (2.1?1.7) mm (tilting movement). Anterior overjet was increased by (1.47?1.76) mm. ③In the vertical dimension,the maxillary molar was extruded slightly by (0.39? 0.46 ) mm, the first premolar was extruded by (0.43?0.61) mm. ④The width between the central point of first maxillary molar was increased by ( 2.8 ?1.1) mm.Conclusions:The Distal-Jet appliance can distalize maxillary molars effectively. However,it may result in distaly tilting of molars and mesial movement of premolars.

The male sex worker(MSW)is a special population group who gain money or other material recompenses by offering sex service to male or female clients.Differing from the general population,they have specific demographic and AIDS-related characteristics Their risk behaviors have resulted in high prevalence rate of HIV and other sex transmitted infection among them,and meanwhile have induced them to engage in sex service.

Biochemistry is one of the important basic subjects in medical college. It is hard for students to master because of its complicated theories and abstract contents. It has been found that carrying out case-teaching method in biochemistry teaching is good for students to arouse study interest and enhance the abilities of autonomic learning, question-analyzing and question-solving as well as consolidate theory knowledge. It is worth generalizing as a new teaching method for biochemistry in medical college.
