Aim To investigate the effect of resveratrol (Res)on septic mice and LPS-insulted H9c2 cells,as well as its involved mechanisms.Methods By use of a mouse cecal ligation and puncture-induced septic model (CLP),the survival of septic mice was evalua-ted after resveratrol treatments.H9c2 cells were insul-ted by LPS and then treated with resveratrol,the mR-NA expressions of TNF-α,SIRT1 and other class III HDAC members were detected using RT-PCR and real-time PCR,Finally,the protein levels of nuclear p65, an important subunit of NF-κB,were measured in H9c2 cells using Western blot assay,to reveal the effect of resveratrol on LPS-induced nuclear transloca-tion of NF-κB.Results Compared with the control septic animals,intraperitoneal injection of resveratrol (1 or 5 mg·kg -1 ·d -1 )significantly increased the survival of septic mice.Furthermore,resveratrol signif-icantly increased mRNA expressions of SIRT1,SIRT2, SIRT6 and SIRT7 in LPS-insulted H9c2 cells.Res-veratrol also remarkably inhibited LPS-induced nuclear translocation of NF-κB.Conclusion An appropriate dose of resveratrol protects septic mouse hearts from the injury induced by LPS through the activation of SIRT family members and the inhibition of NF-κB pathway.

Objective To evaluate the fluid balance and dry weight with whole body bioelectrical impedance analysis (BIA) in patients with maintenance hemodialysis ( MHD). Methods Twenty patients in stable condition with MHD for more than one year were selected ( MHD group). Extra-cellular water ( ECW) and intra-cellular water (ICW) were measured by BIA before hemodialysis, after hemodialysis and at intervals of hemodialysis (24 h and 48 h after hemodialysis), and related parameters were calculated. Whether patients with MHD achieved dry weight at 0 h was analysed, and the effects of average daily urine volume on ECW and ICW were explored. Another 20 healthy volunteers were served as controls. Results Compared with control group, ECW retrieved by ideal body weight was significantly higher before hemodialysis in MHD group (P<0.05). In MHD group, ECW was significantly lower after hemodialysis than that before hemodialysis (P < 0.05). ECW/total body water (TBW) was significantly lower and ICW/TBW was significantly higher after hemodialysis than those before hemodialysis and at intervals of hemodialysis ( P < 0.05). ICW and ECW at each time point were significantly related to body weight. ICW and ECW retrieved by ideal body weight at 0 h and 24 h of those who achieved dry weight were significantly higher than those who did not achieve dry weight ( P < 0.05). ECW and ICW before hemodialysis and 24 h after hemodialysis were significantly lower in those with urine volume <400 mL/d than those with urine volume ≥400 mL/d (P <0.05). Conclusion BIA analysis indicates that changes of fluid balance before hemodialysis, after hemodialysis and at intervals of hemodialysis in patients with MHD are characterized by ECW, and ECW/TBW is a more sensitive parameter. ICW and ECW retrieved by ideal body weight may be sensitive parameters to determine the dry weight in patients with MHD.

Objective To investigate the mechanism of an antifibrotic drug, pirfenidone, in preventing radiation-induced pulmonary fibrosis. Methods Male BALB/C mice were randomized into 4 groups:control group (C), radiation alone group (R), pirfenidone alone group (P), and pirfenidone plus radiation group (P + R). Irradiation was administrated to the whole pulmonary with a single fraction of 12 Gy. The pirfenidone was given 0. 3 ml/kg/d from 3 days prior to irradiation to 12 weeks after.Bronchoalveolar lavage fluid (BALF) from right lung was collected for macrophages counting every monthmonthly until 6 months after irradiation, and left lungs were collected and fixed for. The pulmonary fibrosis was assessed by Masson trichrome staining. The plasma transforming growth factor β(TGF-β) was measured by ELISA. The lung hydroxyproline was evaluated by alkaline solution. Results Compared to group R, the counts of macrophages in BALF in group P + R were reduced by 76% and 62%, and hydroxyproline levels were reduced by 21% and 24% at the 4th and 5th months, respectively. The plasma TGF-β decreased from the 3rd month to 5th month. Pirfenidone markedly ameliorated the severity of lung fibrosis at the 4 - 6th month after radiation. Conclusions Pirfenidone can prevent radiation-induced pulmonary fibrosis, the mechanism of which may be the reduced of inflammation and collagen deposition by decreasing macrophages and hydroxyproline.

To improve the yield of industrial fermentation, a method based on near infrared spectroscopy was presented to predict the growth of yeast.The spectral data of fermentation sample were measured by Fourier-transform near-infrared (FT-NIR) spectrometer in the process of yeast culture.Each spectrum was acquired over the range of 10000-4000 cm1.Meanwhile, the optical density (OD) of fermentation sample was determined with photoelectric turbidity method.After that, a method based on competitive adaptive reweighted sampling (CARS) was used to select characteristic wavelength variables of NIR data, and then extreme learning machine (ELM) algorithm was employed to develop the categorization model about the four growth processes of yeast.Experimental result showed that, only 30 characteristic wavelength variables of NIR data were selected by CRAS algorithms, and the prediction accuracies of training set and test set of the CARS-ELM model were 98.68% and 97.37%, respectively.The research showed that the near infrared spectrum analysis technology was feasible to predict the growth process of yeast.
