Objective Resveratrol can improve nonalcoholic fatty liver disease , but its action mechanisms remain unclear . This study aimed to investigate the protective effect of resveratrol against the free fatty acid ( FFA)-induced apoptosis of human hepatic L02 cells and its possible mechanisms . Methods Human hepatic L02 cells were incubated with FFA and resveratrol for 24 hours.The prepared cells were divided into a blank control , an FFA ( 2 mmol/L) , and a resveratrol group ( 50 μmol/L resveratrol +2 mmol L/FFA).After treatment, we measured the triglyceride (TG), glutathi-one (GSH), and malonaldchyde (MDA) contents and caspase3 ac-tivity in the hepatocytes , determined the apoptosis of the cells by flow cytometry , and detected the protein expression of silent information regulator 1 (SIRT1) by Western blot as well as the mRNA expressions of catalase (CAT), Mn superoxide dismucase (MnSOD), Bcl-2, and Bax by qRT-PCR. Results The TG content and caspase 3 activity in the hepatocytes were significantly increased in the FFA ([3518.±64.2] μmol/L and [5.97 ±0.78] U/g) and the resveratrol group ([201.1 ±60.1] μmol/L and [3.60 ±0.73] U/g) as compared with those of the blank control ([40.2 ±7.4] μmol/L and [2.56 ±0.49] U/g) (both P<0.05), but the caspase3 ac-tivity was markedly decreased in the resveratrol group in comparison with that of the FFA group (P<0.05).Both early and late apop-tosis rates of the hepatocytes were remarkably higher in the FFA ([6.75 ±0.81]%and [8.52 ±0.54]%) and the resveratrol group ([4.94 ±0.44]%and [6.52 ±0.61]%) than those in the blank control ([3.38 ±0.33]% and [2.72 ±0.19]%) ( both P<0.05), with statistically significant differences between the former two groups (P<0.05).The resveratrol group showed significant differences in the GSH content ([100.2 ±8.8] nmol/g), the MDA level ([2.36 ±0.82] mg/g), and the relative expression of SIRT1 (0.84 ±0.04) from the FFA group ([73.8 ±13.1] nmol/g, [3.77 ±0.92] mg/g, and 0.61 ±0.07) and the control ([113.7 ±13.8] nmol/g, [1.85 ±0.41] mg/g, and 0.90 ±0.02) (all P<0.05).The resveratrol group also exhibited statistically significant differences in the relative expressions of the MnSOD , CAT, and Bax genes from the FFA and control groups (P<0.05). Conclusion Resveratrol attenuates FFA-induced apoptosis of human hepatic L 02 cells by activating SIRT1 and reducing the oxidative stress of hepatocytes .

Objective To investigate the roles of TrkA and TrkB in radiation-induced hippocampal neurogenesis impairment.Methods Fifty-six rats were randomized into radiation group and sham control group.Radiation group received whole brain irradiation at a single dose of 10 Gy.The hippocampus were separated from rats in day 1,day 3,day 14 and 1 month after irradiation.Western blot and RT-PCR were applied to detect the protein levels and mRNA levels.Golgi staining was used to observe the dendritic spine of hippocampus.Immunofluorescence was performed to detect neural precursor's proliferation.Results Compared with control group,the numbers of dendritic spine significantly decreased after irradiation and its shape change obviously.Immunofluorescence showed a significant decrease in neural precursor's proliferation comparing with control group (t =6.49,P ＜ 0.05).Protein level of TrkA expression increased (t =2.64,3.06,4.80,2.64,P ＜ 0.05),while the levels of TrkB protein expression decreased significantly (t =4.59,3.06,2.81,2.57,P ＜ 0.05).The mRNA level of TrkA expressions increased (t =4.57,3.06,5.39,5.86,P ＜ 0.05),while the mRNA level of TrkB decreased (t =14.87,11.69,4.98,P ＜ 0.05).Conclusions As a signaling pathways downstream of NGF and BDNF,TrkA and TrkB may play an important role in radiation-induced neurogenesis impairment.

Objective To evaluate the effects of dexmedetomidine on perioperative pulmonary compliance and the expression of Toll?like recep?tor(TLR)?2 and TLR?4 in the peripheral blood during perioperative period in patients undergoing open colorectal cancer radical surgery. Meth?ods Twenty patients with colorectal cancer underwent elective general anesthesia,with ASA gradeⅠ?Ⅱand body mass index(BMI)<30 kg/m2, aged 30 to 68 years old,were enrolled for the study. They were randomly divided into control group(group C,n=10)and dexmedetomidine group (group D,n=10). In group D,dexmedetomidine was infused at a rate of 0.4μg·kg-1·h-1 from the beginning of surgery till 30 min before the end of surgery. The patients in group C received same manipulation as in group D except dexmedetomidine was replaced by normal saline. The mean ar?terial pressure(MAP)and heart rate(HR)were recorded before anesthesia induction(T0),30 min(T2),60 min(T3),and 90 min(T4)after the beginning of surgery,extubation(T6),and 3 min after extubation(T7). Airway pressure and lung dynamic compliance were recorded at T1?T7 time points,respectively. Vein blood samples were drawn to analyze the TLR?2,TLR?4 and tumor necrosis factorα(TNF?α)concentration at T0,T4,T7 and the day after operation(T8),respectively. Results Compared with group C,MAP and HR increased in group D at T6(P<0.05);lung dynamic compliance increased in group D at T4(P<0.05);TLR?2 and TLR?4 concentration in serum decreased in group D at T4, T7 and T8(P<0.05);TNF?αconcentration in serum decreased in group D at T4,T7 and T8(P<0.05). Conclusion Continuous infusion of 0.4μg·kg-1·h-1 dexmedetomidine can help to stabilize hemodynamics,relieve inflammatory stress response,maintain the relative stability of intra?operative hemodynamic parameters,and also can improve the pulmonary dynamic compliance of patients.

Purpose: Asthma is a serious inflammatory disease of the respiratory system in which airway smooth muscle cells (ASMCs) play a key role. This study aimed to investigate the expression of SLC26A2 in human ASMCs (HASMCs) and the regulatory mechanism of SLC26A2 in the proliferation and inflammatory factor production of HASMCs. Materials and Methods: We obtained the asthma-associated differential mRNA SLC26A2 by bioinformatics analysis in childhood acute asthma samples. To investigate its role in airway inflammation and airway remodeling, we treated HASMCs with plateletderived growth factor (PDGF) in an in vitro model and determined SLC26A2 expression in cells using western blotting. Cell proliferation was detected by MTT and EdU assays, and cell contractile phenotype marker proteins were measured. Cell migration and production of inflammatory factors were determined by Transwell and ELISA assays. Additionally, the upstream regulatory miRNA and LncRNA of SLC26A2 were identified by bioinformatics, luciferase reporter gene, and RIP analyses. Results: SLC26A2 was significantly upregulated in bioinformatics analysis of pediatric asthma-related sample. PDGF treatment up-regulated SLC26A2 expression in HASMCs, whereas the knockdown of SLC26A2 inhibited PDGF-stimulated proliferation, migration, and production of inflammatory factors, and enhanced the expression of cell contractile phenotype marker proteins in HASMCs. Luciferase reporter and RIP experiments validated that NEAT1 targeted miR-9-5p to regulate SLC26A2, thereby influencing the biological function of PDGF-induced HASMCs. Conclusion These findings indicate that NEAT1-mediated miR-9-5p targeting of SLC26A2 inhibits the PDGF-induced proliferation and production of inflammatory factors in HASMCs. These findings highlight potential therapeutic targets for asthma and airway inflammation.

Objective? To explore the effects of knowledge and skill training on diabetes knowledge, attitude and practice and skill levels in community nurses in Guangzhou City and to provide effective measures to improve diabetes-related knowledge and skill levels of community nurses. Methods? Totally 40 community nurses from Liwan District, Guangzhou were selected as the subjects of training between October and November 2017 by convenient sampling. These community nurses received diabetes knowledge and skill training for 2 months after a investigation with questionnaire (diabetes knowledge questionnaire for community nurses, diabetes management attitude questionnaire, diabetes management behavior questionnaire, and diabetes management skill assessment scale). The community nurses' diabetes knowledge, diabetes management attitude and diabetes management behavior and skill scores were compared before and after training. Results? The community nurses' scores of diabetes knowledge and diabetes management attitude after training significantly increased than those before training (P＜0.05); and the score of diabetes management behavior after training increased than that before training,but there was no significant difference (P＞ 0.05). The score of the nurses' insulin injection skills and portable glucose meter were higher than that before training (P＜ 0.05). Conclusions? Training for community nurses helps to improve their diabetes knowledge and operation skills as well as their attitude towards diabetes management and enhance their awareness of the importance of diabetes management in the community.
