This study is to investigate the effects of paeoniflorin on cerebral blood flow and the balance of PGI2/TXA2 of rats with focal cerebral ischemia-reperfusion injury. A total of 72 SD rats (3) were randomly divided into 6 groups: sham operation group, cerebral ischemia-reperfusion model group (I/R gourp), low (10 mg.kg-1), middle (20 mg.kg-1) and high (40 mg.kg-1) doses of paeoniflorin groups and nimrnodipine group. Focal cerebral ischemia in rats was made by inserting a monofilament suture into internal carotid artery for 90 min and then reperfused for 24 h. The effects of paeoniflorin on neurological deficit scores and the infarction volume of brain were detected. Relative regional cerebral blood flow (rCBF) was continuously monitored over ischemic hemispheres by laser-Doppler flowmetry (LDF). The expression of COX-2 in hippocampal CAl region was estimated by immunohistochemistry and the contents of prostacyclin I2 (PGI2), thromboxane A2 (TXA2), and ratio of PGIJ2/TXA2 in serum were measured by ELISA kits. Paeoniflorin significantly ameliorated neurological scores, reduced the infarction volume, and increased regional cerebral blood flow relative to the I/R group. In addition, paeoniflorin could inhibit COX-2 expression and the release of TXA2 and prevent the downregulation of PGI2 induced by I/R injury. The neuroprotective effects of paeoniflorin against focal cerebral ischemia-reperfusion rats might be attributed to improve the supply of injured hemisphere blood flow and adjust the balance between PGI2/TXA2.

OBJECTIVETo discuss the effect of surgical staging and using craft bone with vancomycin for the treatment of calcaneal fractures.

METHODSFrom January 2006 to December 2012,13 patients with open calcaneal fractures were treated including 9 males and 4 females with an average of 35.2 years old ranging from 23 to 66. All cases were emergency cases. According to Sanders classification of calcaneal fractures, 2 cases were type II, 7 cases were type III, 4 cases were type IV. According to Gustilo-Anderson soft tissue injury classification, 8 cases were type II, 2 cases were type III A, 2 cases were type III B, 1 case were type III C. Firstly a thorough debridement or VSD procedures were applied,secondly calcaneal fracture were treated with open reduction, plate fixation and bone graft complex with antibiotics. Based on clinical examination, radiographic evaluation, and American Foot and Ankle Surgery Society (AOFAS), ankle function were evaluated after operation.

RESULTSOpen wounds were headed after dressing and repairing,, lateral calcaneal wound were healed during the first period. All patients were followed up for 6 to 36 months (means 14.5 months). Fracture healing time was 14 to 20 weeks (means 16.2 weeks). Last follow-up AOFAS ankle-hindfoot score was (80.0 +/- 7.4) ranging from 55 to 95.

CONCLUSIONFor patients with open fractures, through reasonable clinical evaluation, staging operation, using bone graft with antibiotics can reduce the incidence of postoperative wound infection and promote fracture healing.

Aim To investigate the influence of Shen-mai injection ( SMI ) on the expression of cytochrome P450(CYP450) system in rat′s hearts. Methods Rat hearts were prepared after a fourteen-day continuous administration of SMI. The expression of several CYP genes, ANP, BNP and EPHX2 were measured by qPCR. Results SMI induced the increase in the ex-pression of other CYP genes except CYP2 B1、CYP4 A3 and CYP4 F6;HSI caused an induction of CYP2 E1 , CYP4A3,CYP4F1 and EHPX2 as compared with the control. In addition, there was a significant induction of ANP, BNP and EHPX2 and a significant inhibition of CYP2B1 and CYP2C11 after treated with MDI. Conclusion Although there is no significant change in the gene expression of CYP2 B1 after the treatment with SMI, but there is a general trend of induction, and MDI shows a significant inhibition of CYP2 B1 , therefore HSI has greater effect on CYP 2 B 1 than MDI . SMI causes a significant induction of CYP2 E1 , CYP4F1 and EHPX2 , similarly there is an induction of CYP2E1,CYP4F1 and EHPX2 by HSI and MDI, indi-cating that Hongshen and Maidong are both involved in the induction. MDI has a greater inductive effect than HSI on ANP and BNP. SMI is widely used for the treatment of cardiovascular diseases due to its regula-tion of CYP2J3、ANP and BNP mRNA expression.

OBJECTIVETo investigate the parents' compliance in non-hospital settings during the operation of expressed breast milk bank.

METHODSIn September 2014, a questionnaire survey was carried out to investigate the parents' willingness about feeding the inpatient neonates with maternal expressed breast milk, to evaluate the effectiveness of the breast milk feeding supporting system, and to monitor the compliance in non-hospital settings during the delivery of maternal expressed breast milk. Improvements in education were made according to the results. A second survey was done in September 2015.

RESULTSA total of 340 questionnaires were sent out, and 338 usable questionnaires were returned. According to the time when the questionnaires were sent out, they were divided into two groups: 2014 group (n=229) and 2015 group (n=109). The age of most mothers was 20-30 years in the 2014 group and 30-40 years in the 2015 group. Most mothers delivered at the West China Second Hospital of Sichuan University in both groups, but the 2015 group had a significantly higher proportion than the 2014 group (74.3% vs 61.6%; P<0.05). Guidance was given to mothers in the presence of insufficient breast milk production in both groups, but the 2015 group had a significantly higher proportion than the 2014 group (91.7% vs 79.9%; P<0.05). Both groups had good family compliance in the collection, storage, and transport of breast milk. There were no significant differences in their compliance with washing hands, sterilizing instruments, and using a clean special refrigerator between the two groups. The expressed breast milk was transported strictly according to the procedure in both groups, but the 2015 group had a significantly higher proportion than the 2014 group (100% vs 87.1%; P<0.05).

CONCLUSIONSBefore and after improvements in the health education, most parents have good compliance in the collection, storage, and transport of breast milk.
