The relatively weak interactions between some non-charged amino acids with CO were investigated theoretically by using density functional theory （DFT） method. The stretching frequency of CO correlates well with its bond length followed the Badger＇s rule, and the correlation between binding energy and Mulliken charge partition of CO was also investigated for the first time. 2007 Ying Wu Lin.

AIM To verify the value of Gutuo Jiejiu decoction in improving the survival of patients with severe alcoholic hepatitis(SAH).METHODS We performed a retrospective cohort study in consecutive patients diagnosed with SAH at the Teaching Hospital of Chengdu University of Traditional Chinese Medicine and Shuguang Hospital, Shanghai University of Traditional Chinese Medicine. The traditional Chinese medicine formula Gutuo Jiejiu decoction was employed as an exposure factor. Patients from the Teaching Hospital of Chengdu University of Traditional Chinese Medicine who had been treated with Gutuo Jiejiu decoction + prednisone were assigned to an observation group, and patients from Shuguang Hospital, Shanghai University of Traditional Chinese Medicine who had been treated with prednisone alone were selected as a control group. A retrospective analysis was performed by comparing age, alcohol intake, and clinical parameters of liver injury beforeand after treatment. Additionally, the 3-and 12-mo survival rates and the occurrence of complications were *** One hundred and twenty-eight eligible patients were selected from 175 cases with SAH, of which 68 were assigned to the observation group and the other 60 to the control group. No significant difference was found in the patients' baseline characteristics(P > 0.05). However, significant improvements of 90-d survival rate [56/68(82.4%) vs 27/60(45.0%), P = 0.0000] and 365-d survival rate [48/68(70.6%) vs 13/60(21.7%), P = 00000] were observed in the observation group after treatment. After the first 3 mo of treatment, more improvements in the clinical parameters and scoring systems related to liver injury occurred in the observation group than in the control group(P < 0.05). After treatment for 12 mo, the differences in the clinical parameters and scoring systems related to liver injury between the two groups were more significant(P < 0.05). No significant differences in complications and adverse effects were found b

A two-stage process was used to produce nano-composite epoxy coatings. The first step involved preparing nano-AI concentrates with high concentration and low viscosity, and the second step produced nano- composite epoxy coatings by mixing the nano-AI concentrates and epoxy resin. Later, the coating was examined with immersion and salt spray tests. The coatings were characterized by electrochemical impedance spectroscopy （EIS）, scanning electron microscopy （SEM） and X-ray photoelectron spectroscopy （XPS）. The results showed that the 5% nano-AI significantly improves the corrosion resistance of the coatings. There are two effects of nano-AI on the coating. Nano-AI is corroded initially to protect the substrate from corrosion, and then the aluminum oxide and aluminum hydroxide were produced after corrosion of nano-AI, which hindered the transmission of corrosion fluid into the coatings.

Nerve growth factor（NGF） promotes axonal growth in PC12 cells primarily by regulating the RTK-RAS-MEK-ERK pathway. Panaxydol, a polyacetylene isolated from Panax notoginseng, can mimic the effects of NGF. Panaxydol promotes neurite outgrowth in PC12 cells, but its molecular mechanism remains unclear. Indeed, although alkynol compounds such as panaxydol can increase intracellular cyclic adenosine 3′,5′-monophosphate（cAMP） levels and the ERK inhibitor U0126 inhibits alkynol-induced axonal growth, how pathways downstream of cAMP activate ERK have not been investigated. This study observed the molecular mechanism of panaxydol-, NGF-and forskolin-induced PC12 cell axon growth using specific signaling pathway inhibitors. The results demonstrated that although the RTK inhibitor SU5416 obviously inhibited the growth-promoting effect of NGF, it could not inhibit the promoting effect of panaxydol on axonal growth of PC12 cells. The adenylate cyclase inhibitor SQ22536 and cAMP-dependent protein kinase inhibitor RpcAMPS could suppress the promoting effect of forskolin and panaxydol on axonal growth. The ERK inhibitor U0126 inhibited axonal growth induced by all three factors. However, the PKA inhibitor H89 inhibited the promoting effect of forskolin on axonal growth but could not suppress the promoting effect of panaxydol. A western blot assay was used to determine the effects of stimulating factors and inhibitors on ERK phosphorylation levels. The results revealed that NGF activates the ERK pathway through tyrosine receptors to induce axonal growth of PC12 cells. In contrast, panaxydol and forskolin increased cellular cAMP levels and were inhibited by adenylyl cyclase inhibitors. The protein kinase A inhibitor H89 completely inhibited forskolin-induced axonal outgrowth and ERK phosphorylation, but could not inhibit panaxydol-induced axonal growth and ERK phosphorylation. These results indicated that panaxydol promoted axonal growth of PC12 cells through different pathways down
