OBJECTIVETo investigate the effect of peroxisiome proliferator activated receptor-α (PPAR-α) on the regulation of cardiomyocyte hypertrophy and the relationship between the effect of PPAR-α with PI3K/Akt//mTOR signal pathway.

METHODSCardiomyocyte hypertrophy was induced by isoproterenol (ISO). The cell surface area was measured by image analysis system (Leica). The expressions of atrial natriuretic peptide (ANP), β-myosin heavy chain (β-MHC) and PPAR-α mRNA were detected by qRT-PCR. The protein expressions of Akt, mTOR and P70S6K were detected by Western blot. The expression of PPAR-α was suppressed by RNAi.

RESULTS(1) The expression of PPAR-α was significantly reduced in cardiomyocyte hypertrophy. PPAR-α activator Fenofibrate (Feno) increased the expression of PPAR-α and suppressed cardiomyocyte hypertrophy. The inhibitory effect of Feno on cardiomyocyte hypertrophy was reversed by PPAR-α RNAi. (2) Feno significantly inhibited the increase of the protein expressions of p-Akt, p-mTOR and p-p70S6K in ISO induced cardiomyocyte hypertrophy, which could be blocked by PPAR-α RNAi. (3) PI3K antagonist LY294002 (LY) or mTOR antagonist rapamycin (RAPA) markedly-inhibited cardiomyocyte hypertrophy. The inhibitory effects of LY or RAPA on cardiomyocyte hypertrophy were reversed by PPAR-α RNAi.

CONCLUSIONPPAR-α can negatively regulate cardiomyocyte hypertrophy. The effect might be associated with PPAR-α inhiting PI3K/ Akt/mTOR signal pathway.

Objective:To investigate the effectiveness and safety of manual acupuncture for memory loss and sleep quality in chronic insomniacs.Methods:A total of 60 eligible participants were enrolled and randomized into either a treatment group or a control group,with 30 cases in each group.The treatment group was intervened by manual acupuncture whereas the control group was given sham acupuncture.In the two groups,the interventions were offered once every other day and three times a week,for 8 weeks in total.Before and after the treatment,Pittsburgh sleep quality index (PSQI) and eventrelated potentials (ERPs) were used to assess the patients' sleep quality and memory,respectively.Meanwhile,adverse events were monitored and recorded.Results:After 8-week treatment,both the treatment group and the control group showed a significant decrease in the PSQI global score (P＜0.001,P＜0.01),and the decrease in the treatment group was more significant than that in the control group (P＜0.001).The intra-group comparisons of ERPs indicated that,the latencies of N1 and P3 were shortened and the amplitudes of N1 and P3 were increased in the treatment group after the intervention,and the differences were statistically significant (P＜0.05,P＜0.001);in the control group,there were no significant changes in the latency and amplitude after the treatment (P＞0.05).The between-group comparisons of ERPs showed that the treatment group was more effective than the control group in shortening the latency of P3 (P＜0.01).Conclusion:Acupuncture can be a safe and effective treatment option for chronic insomnia coupled with memory impairment.

Nanoparticle delivery systems have good application prospects in the field of precision therapy, but the preparation process of nanomaterial has problems such as short in vivo circulation time, easy recognition, and clearance by the immune system in the body. In recent years, biomimetic nanoparticle delivery systems mediated by natural cell membranes have become a research hotspot to address these issues. The natural membrane biomimetic nanoparticle delivery system cleverly integrates the advantages of natural biofilm "autologous" and "artificial" functional carriers by using endogenous cell membranes to modify the surface of nanocarriers, endowing them with characteristics such as tumor targeting, low immunogenicity, and long blood circulation. Currently, biomimetic nanoparticle delivery systems have been used in the treatment of malignant tumors, cardiovascular diseases, bacterial infections, and other diseases. This paper analyzes the development status and current research hotspots of natural cell membrane camouflaged biomimetic nanoparticle delivery systems mainly reviews the latest research progress of red blood cell membrane camouflaged biomimetic nanoparticle delivery systems in the field of disease treatment in recent years. It focuses on exploring the advantages, future development prospects, and limitations of biomimetic nanoparticle delivery systems based on red blood cell membrane camouflage in improving drug delivery, to provide a reference for the in-depth research and development of this system.

Objective To compare the differences between conventional Mammotome biopsy of benign breast tumor and Mammotome biopsy under the electronic clinical pathway,in order to provide basis for Mammotome biopsy of benign breast tumor under clinical pathway.Methods 160 patients with benign breast tumor in affiliated Hospital of Binzhou Medical College from January 2010 to December 2011 were divided into the control group (80 patients treated with conventional Mammotome biopsy) and the observational group (80 patients treated with Mammotome biopsy under clinical pathway).Patients' waiting days before surgery,days in hospital,total cost,obedience,health knowledge,postoperative complications and satisfaction between two groups were compared.Results Days before surgery in the observational group were (1.25 ± 0.33),and days in hospital were (4.28 ± 1.52),both of which were shorter than those in the control group (2.44 ± 0.65),(6.02 ± 4.12).The differences were statistically significant (t =7.48,9.86,respectively ; P ＜ 0.05).Total cost in the observational group was (4 758.48 ± 686.34) yuan,fewer than that in the control group which was (4 998.76 ± 778.32) yuan,and the differences were statistically significant (t =3.46,P ＜ 0.05).Compared with the control group,the observational group had better obedience rate (97.5％ vs 85％),better mastering of health knowledge (97.5％ vs 82.5％),and higher satisfaction (97.5％ vs 85％).The differences were statistically significant (x2 =7.83,10.0,7.83,respectively ; P ＜ 0.05).Conclusions Mammotome biopsy under clinical pathway can further improve patients' obedience and satisfaction,reduce days in hospital,total cost and postoperative complications,thus should be promoted actively.
