Objective To investigate the protective effect of Yulangsan polysacharide ( YLSPS) and mechanism against ibuprofen-induced liver injury in mice. Methods The mice were randomly divided into the blank control(NC), the model control,YLSPS at 150 mg·kg-1 , 300 mg·kg-1 ,600 mg·kg-1 groups and biphenyldicarboxylate (150 mg·kg-1 BPDC) group. The mice were orally administered with corresponding agents once per day for consecutive 14 days, whereas the blank control group and model control group were orally administered with saline. Except the blank control group, all the other mice were orally administered IBU 200 mg·kg-1 body weight 2 h after last lavagedof medicimes. The mice were fasted and watered ad lib for 20 h after model establishment. Activities of ALT,AST and ALP,content of T-BiL,TNF-α,IL-6 in serum;activities of SOD,GSH-Px and content of MDA in liver tissue were detected. The morphological pathology test was used to examine degrees of hepatic injury. Results Compared with the model control, YLSPS could obviously reduce activities of ALT,AST and ALP,content of T-BiL, MDA,TNF-α and IL-6, and increase SOD,GSH-Px and CAT (P<0. 05), and then lessen the hepatic injury. Conclusion YLSPS showed potential protective effect against ibuprofen-induced liver injury in mice, the mechanism may be related to attenuating free radical injury and inhibiting lipid peroxidation and lowering release of inflammatory factors.

[Objective] To observe the influence of rats serum SOD and cardiac function with qi deficiency syndrome through the factors of the acupuncture point injection with different reinforcing and reducing methods. [Methods] To establish SD rat heart-qi deficiency syndrome model with the compound factors of the feeding, load forced swimming and large dose propranolol. The rats were randomly divided into blank control group, model group, Zusanli(St. 36) Shenqi Fuzheng injection reinforcing method group, Zusanli(St. 36) Shenqi Fuzheng injection reducing method group. Each acupoint injection of 0.20ml, one time a day, for 10 consecutive days. Determine of serum SOD activity values respectively and detect cardiac function correlated hemodynamic indexes. [Results] (1) The activity of serum SOD in model group rats was significantly lower than control group( P<0.01);Treated groups and model group had significant difference(P<0.05 or P<0.01);Zusanli(St. 36) injection reinforcing method group and Zusanli(St. 36) reducing method group had significant differences(P<0.01);(2) The cardiac function of rats in model group decreased significantly, corresponding heart function index of each treatment groups had changes and obvious differences. The maximum ventricular rats model of the internal pressure, left ventricular systolic pressure ,the maximum rate of rise of left ventricular pressure, heart rate and other indicators of Zusanli(St. 36) Shenqi Fuzheng injection reinforcing method group were more than indexes of Zusanli(St. 36) Shenqi Fuzheng injection reducing method group( P<0.01). [Conclusion] Acupoint injection of different reinforcing-reducing manipulations had different effect on the treatment of disease, and Zusanli(St. 36) injection reinforcement treatment of heart-qi deficiency syndrome model rats was significantly better than the other groups.

Objective To explore the risk factors for methicillin-resistant Staphylococcus aureus (MRSA)infection of refractory wound,and provide reference for clinical prevention and control.Methods Clinical data of patients who were isolated Staphylococcus aureus (SA)from wound at the burn ward in a hospital from January 2006 to December 2013 were analyzed,patients were divided into four groups according to whether the isolated SA were MRSA and whether SA were from refractory wound or from non-refractory wound.Risk factors for MRSA infection of refractory wound were analyzed. Results A total of 112 isolates of SA were isolated from wound,statistical differences existed in the length of hospital stay,recent invasive operation,and recent antimicrobial use between patients in refractory wound MRSA group and refrac-tory wound methicillin-sensitive SA (MSSA)group (all P <0.05);non-conditional logistic regression analysis revealed that length of hospital stay>30 days (OR 95% CI :1.14-30.69)and recent invasive operation (OR 95% CI :1.41 -17.84) were independent risk factors for refractory wound MRSA infection.There were statistically differences in previous MRSA infection,burn depth,recent operation and recent antimicrobial use between refractory wound MRSA group and non-refrac-tory wound MRSA group(all P <0.05);non-conditional logistic regression analysis revealed that recent antimicrobial use (OR 95% CI :2.080-26.800)was independent risk factor for the persistence of MRSA infection of refractory wound. Conclusion Shortening the length of hospital stay,reducing invasive operation,and using antimicrobial agents ra-tionally are helpful for the prevention and control of MRSA infection of refractory wound.
