Xuefu Zhuyu decoction (XFZYD) is a famous traditional Chinese medicine (TCM) formula, is widely used in the treatment of cardiovascular and cerebrovascular diseases in China over one hundred years. But its effect on antioxidant and drug-metabolizing enzymes are unknown. This study was to observe the effects of Xuefu Zhuyu decoction (XFZYD) on the activities of antioxidant and drug metabolism enzymes (DMEs) in liver of rats. Male SD rats, treated with XFZYD at the dosage of 3.51, 7.02 and 14.04 g x kg(-1) per day for 15 days, serum were collected, tissue fluid, cytosols and microsomes isolated from liver tissues were prepared by centrifugation according to the standard procedure, the activities of antioxidant enzymes and drug-Metabolizing Enzymes were determined by UV-V is spectrophotometer. In serum, the activities of AST was not significantly affected by the treatment with XFZYD, at the high- est dose, the levels of ALT, Cr and BUN were significantly decreased (P < 0.05). GPX were significantly increased at the dose of 7.02, 14.04 g x kg(-1) (P < 0.05), CAT were significantly increased at the highest dose (P < 0.05). T-SOD was not significantly af- fected by this treatment. In the liver tissue, GPX was significantly increased at the dose of 3.51, 7.02 g x kg(-1) (P < 0.05), GST, CAT and T-SOD were not significantly affected following this treatment. In cytosols, GST was significantly increased at the dose of 3.51 g x kg(-1) (P < 0.05), T-SOD was remarkable induced at the dose of 3.51 and 7.02 g x kg(-1) (P < 0.05). In microsomes, XFZYD had no significant effect on Cytochromeb5, NADPH-Cytochrome P450 reductase, CYP3A, CYP2E1 and UGT, XFZYD significantly in- duced GST at the dose of 3.51 and 7.02 g x kg(-1) (P < 0.05), and the level of GSH were significantly increased by XFZYD at the dose of 3.51, 7.02 and 14.04 g kg(-1) (P < 0.05). These findings suggest XFZYD can induce the activities of GPX, CAT, SOD, GST and increase GSH level in liver of rats, which indicate XFZYD may have detoxification and antioxidant functions.

Objective To confirm the effects of statin therapy on mortality of patients with acute lung injury/acute respiratory distress syndrome (ALI/ARDS). Methods PubMed/Medline, Embase, Web of Science andCochrane Central Register of Controlled Trials were searched for articles using the terms acute lung injury, ALI,acute respiratory distress syndrome, ARDS, statin, simvastatin and rosuvastatin updated to November 17,2015. Randomized controlled trial (RCT) or observational cohort studies investigating the effects of statin therapy onmortality in patients with ALI or ARDS were all identified, without date or language restriction. The control group wasgiven conventional treatment, while the experimental group was treated with statins additionally. The primary outcomewas in-hospital mortality. Meanwhile, ventilator-free day, intensive care unit (ICU)-free day, ICU length of stay (LOS)and ICU mortality were also analyzed. RevMan 5.2 and STATA 13 software were used for systematic review and Metaanalysis, and funnel plot was used to analyze the publication bias. Results A total of five trials including threerandomized controlled trials and two observational studies were included. Among 1636 patients enrolled in the study,there were 739 patients in experimental group, and 897 in control group. It was shown by Meta analysis that there was nosignificant difference in in-hospital mortality between experimental group and control group [relative risk (RR) = 0.96,95% confidence interval (95%CI) = 0.79-1.15, P = 0.63]. The subgroup analysis based on RCT and cohort study, or thesubgroup analysis of different statins showed that there was no significant difference in in-hospital mortality betweenthe experimental group and the control group (both P > 0.05). There were no significant differences in ventilator-freedays [mean difference (MD) = 1.41, 95%CI = -0.32-3.13, P = 0.11], ICU-free days (MD = -0.23, 95%CI = -1.61-1.15,P = 0.75), ICU length of stay (MD = -1.03, 95%CI = -6.55-4.50, P = 0.72), or ICU mortality (RR = 0.88, 95%CI =0.68-1.14, P = 0.33) between the experimental group and the control group. It was shown by funnel plot that there was nopublication bias in in-hospital mortality. Conclusion The systematic review and meta-analysis suggests that statin may not be associated with a significant reduction in mortality, ventilator-free day, ICU-free day and ICU length of stayin patients with ALI/ARDS.

OBJECTIVETo explore the clinical symptom and effect of arthroscopic treatment of symptomatic anterior cruciate ligament (ACL) cysts of the knee.
METHODSClinical data from 12 symptomatic ACL cysts patients from January 2005 to December 2010 were retrospectively analyzed,including 8 males and 4 females,with an average age of (33.7±9.5) years old (ranged, 19 to 53 years old). The locations were the left knee in 5 cases and the right knee in 7 cases. The disease duration ranged from 3 to 48 months,with a mean of (15.8±13.2) months. All cysts were arthroscopically resected. Range of motion was measured preoperatively and postoperatively, and Lysholm scoring system was used to evaluate the knee function.
RESULTSAll the incisions healed by first intention, and no complications occurred. Twelve patients were followed up for an average of (32.3±6.6) months(ranged, 24 to 48 months). The symptoms of arthralgia,swelling and interlocking of the affected knees disappeared. There was no recurrence during the follow-up. There were significant differences in the range of motion and Lysholm score between pre-operation and post-operation.
CONCLUSIONArthroscopic surgery, showing its advantages of minimal invasion and rapid recovery,is an effective measure in the treatment of ACL cysts.

The rice water weevil (RWW) Lissorhoptrus oryzophilus Kuschel (Coleoptera: Curculionidae) is an invasive insect pest of rice Oryza sativa L. in China. Little is known about the interactions of this weevil with indigenous herbivores. In the present study, adult feeding and population density of the weevil, injury level of striped stem borer Chilo suppressalis (Walker) (Lepidoptera: Pyralidae) and pink stem borer Sesamia inferens (Walker) (Lepidoptera: Noctuidae) to rice, as well as growth status of their host plants were surveyed in a rice field located in Southeastern Zhejiang, China, in 2004 with the objective to discover interspecific interactions on the rice. At tillering stage, both adult feeding of the weevil and injury of the stem borers tended to occur on larger tillers (bearing 5 leaves) compared with small tillers (bearing 2~4 leaves), but the insects showed no evident competition with each other. At booting stage, the stem borers caused more withering/dead hearts and the weevil reached a higher density on the plants which had more productive tillers and larger root system; the number of weevils per tiller correlated negatively with the percentage of withering/dead hearts of plants in a hill. These observations indicate that interspecific interactions exist between the rice water weevil and the rice stem borers with negative relations occurring at booting or earlier developmental stages of rice.

OBJECTIVETo observe MET-associated alteration during the trans-differentiation from MSCs to neuron-like cells, and to explore the possible molecular mechanism.
METHODSBone marrow MSCs were isolated from rat femur and purified in continuous cell culture. After induced differentiation to neuron-like cells by the combination of butylated hydroxyanisole (BHA) and dimethyl sulfoxide (DMSO), cells were tested by comparative polymerase chain reaction (PCR) for the relative expression of MET biomarkers and transcription factors, and for cell cycle by flow cytometry. Meanwhile, target genes of Wnt/β-catenin pathway were also analyzed by comparative PCR to determine the possible involvement.
RESULTSIn MSC-induced neuron-like cells, MET-associated transcription factors such as Snail, Slug, ZEB1, ZEB2, and Twist were significantly attenuated in expression level. The Mesenchymal marker Vimentin expression level was increased. Membrane protein E-cad was slightly down-regulated, while N-cad level was marginally elevated. Percentage of proliferating cells (S phase in cell cycle) markedly shrank from 40.42% for MSCs to 6.76% for MSC-derived neuron. Additionally, Wnt/β-catenin target genes β-catenin and c-myc were decreasingly expressed.
CONCLUSIONChemically induced trans-differentiation from MSC to neuron caused similar MET-featured alteration in gene expression and proliferation to known MET, which might be underlied by deactivation of Wnt/β-catenin pathway.
