[Objective]To explore the effect of HSYA on pro/anti-inflammatory cytokine′s levels and mRNA expression in peripheral blood of mice.with sepsis.[Methods]Dividing NIH mice into four groups,as normal group,sham group,CLP group and HSYA group,24 mice in each group. The CLP sepsis mouse model was established. HSYA(120 mg/kg)were injected intravenously at 12 h before the operation ,and 0 h and 12 h following CLP ,and other groups were given normal saline. observed the animals behavior changes,measured the levels WBC,PLT,ALT,AST,BUN in serum,detected the levels and mRNA expression of IL-6, IL-10 ,TNF-α in peripheral blood. cultured of peripheral blood bacteria loads.[Results]24 h after surgery ,mice in CLP group appeared furring,feces residues on anus etc. compared to normal group,sham group and HSYA group,WBC,PLT,ALT,AST, BUN,levels and mRNA expression of IL-6,IL-10,TNF-αshowed significant increases,it was also found that bacterial load was significant increased in model group.[Conclusions]HSYA has a therapeutic effect in mice with sepsis ,can reduce bacteria into the blood,and inhibit inflammatory mediators which caused tissue damage.

BACKGROUND:Kinesio taping has been widely used as a means of sports protection,but its role as a means to correct abnormal biomechanical changes of the lower limbs during side-step cutting remains unclear. OBJECTIVE:To analyze and compare the changes in lower limb kinematics and dynamics when the subjects complete the side-step cutting of the knee joint under the conditions of kinesio taping,placebo taping and blank control. METHODS:Thirty-nine male college students majoring in basketball were recruited as subjects.Each subject was tested with kinesio taping,placebo taping or no taping.The mechanical correction method was used to patch the dominant knee joint of each subject.The run-up speed of 4.5-5.5 m/s was selected to complete the 45° side-step cutting motion,and the kinematics and kinetics data were collected synchronously by the three-dimensional dynamic capture system and the force measuring platform.The kinematics and kinetics parameters at the moment of initial touchdown and peak ground reaction force were selected for data analysis.SPSS 27.0 software was used for statistical analysis of the test data. RESULTS AND CONCLUSION:Kinematic indexes:compared with no taping and placebo taping,the hip abduction and knee valgus angles at the initial touchdown moment were significantly decreased when kinesio taping was used(P<0.05);at the moment of peak lateral ground reaction force,the angles of hip abduction,knee valgus and ankle plantar flexion decreased significantly(P<0.05),and the knee flexion angle was significantly increased(P<0.05).Kinetic indexes:Compared with no taping,both kinesio taping and placebo taping significantly reduced hip abduction and external rotation torque,knee valgus and external rotation torque at the moment of initial touchdown(P<0.05),and significantly reduced peak vertical ground reaction force and peak horizontal backward ground reaction force(P<0.05);in addition,kinesio taping significantly reduced peak lateral ground reaction force compared with no taping and placebo taping(P<0.05).These results indicate that kinesio taping of the knee joint may improve some kinematic and kinetic indexes associated with lower limb injury risk factors during the completion of the side-step cutting in basketball specialized college students to some extent,and may have a positive effect on the prevention of injury during the side-step cutting.In addition,the trends in the effects of placebo taping and kinesio taping on the knee joint are more consistent in terms of changes in some indexes,suggesting that there may be a placebo effect on the mechanism of action of kinesio taping.

Objective To establish a clinical scoring system for the prognosis of patients with single large hepatocellular carcinoma (HCC) after hepatectomy.Methods 268 patients with single large HCC who underwent hepatectomy in West China Hospital of Sichuan University from January 2009 to December 2013 were included in this prospective study. There were 227 males and 41 females, of which 198 cases aged≤60 years old, 70 aged>60 years old. The informed consents of all patients were obtained and the local ethical committee approval was received. The patients' survival were observed. The independent risk factors for postoperative prognosis of patients with single large HCC were selected by Cox proportional risk regression mode. Based on the risk factors, the prognostic scoring system for single large HCC wasestablished. The scoring system was tested through survival analysis by Kaplan-Meier and Log-rank test. Results The median overall postoperative survival was 45 months, and the tumor-free survival was 31 months. Platelet-to-lymphocyte ratio (PLR)≥107, tumor diameter≥6.8 cm and positive microvascular invasion (MVI) were the independent risk factors for postoperative overall survival and tumor-free survival in patients with single large HCC (HR=1.004, 1.092, 2.233 and 1.003, 1.062, 1.534; P<0.05). Every independent risk factor was assigned 1 point. All patients were divided into low risk group (0 point), moderate risk group (1-2 points) and high risk group (3 points). The 5-year survival rate of high risk group was 25.4％, and that of moderate and low risk group was 33.2％ and 52.1％ respectively, where significant difference was observed (χ2=23.1, P<0.05). Similar Results were observed when the scoring system was used in patients with or without cirrhosis.Conclusions PLR≥107, tumor diameter≥6.8 cm and positive MVI are the independent risk factors for the prognosis of patients with single large HCC after resection. The prognostic scoring system established in this study can be used to predict the postoperative long-term survival of patients.
