Through all times and around the world,those who discipline themselves with high ethical standards can be regarded as truly noble men successfully taking advantage of moral authority of the people.Books on the art of war in ancient China raised a couple of ethical requirements for those superior military officers and governors.If officers want to affect his men′s mental state and generate the army′s spirit of combat effectiveness,they must assume a certain degree of ethical responsibility.Also,active share of ethical responsibility calls to take the initiative to develop a sense of ethical responsibility.Furthermore,to develop a sense of ethical responsibility calls for the building of ethical self-consciousness to participate in the training of ethical responsibility.However,the participation of ethical building consciousness can not be separated from the ethical sense of responsibility.In conclusion,each part of the three links,complementing each other,can not be biased and separated.

Objective To design and prepare recombinant mutant human high mobility group box 1 protein (HMGB1s) that can combine with HMGB1 receptors but cannot produce inflammatory effect, and accordingly lead to the creation of a new potential agent for anti-inflammatory therapy. Methods This experiment was based on successful clone and expression of human HMGB1.Six mutant HMGB1 cDNA were designed and constructed by one step inverse PCR. They were cloned into prokaryotic expressive vector pQE80L and followed with production of mutant HMGB1s and identification by Western blotting.

Objective To evaluate the role of spinal c?Jun N?terminal kinase ( JNK ) signaling pathway in incisional pain in rats. Methods Sixty?three adult male Sprague?Dawley rats, weighing 200-250 g, were randomly divided into 3 groups ( n=21 each) using a random number table: incisional pain group ( IP group) , dimethyl sulfoxide ( DMSO) group, and JNK inhibitor SP600125 group ( SP group) . A 1?cm longitudinal incision was made through skin, fascia and muscle of the plantar aspect of the hindpaw in anesthetized rats. In group DMSO, 10% DMSO 10 μl was injected intrathecally at 30 min before surgery. In group SP, SP600125 25 μg (in 10 μl of 10% DMSO) was injected intrathecally at 30 min before sur?gery. Six rats in each group were sacrificed, and the mechanical paw withdrawal threshold ( MWT) and thermal paw withdrawal latency ( TWL) were measured at 24 h before establishment of the model and 2, 6, 24, 48 and 72 h after establishment of the model. After measurement of the pain threshold at 24 h before establishment of the model and 6, 24, 48 and 72 h after establishment of the model, the lumbar segment of the spinal cord was removed for determination of the expression of phosphorylated JNK ( p?JNK) by im?munofluorescence. Results The MWT was significantly lower, the TWL was shorter, and the expression of p?JNK was lower at each time point after establishment of the model than at 24 h before establishment of the model in group IP (P<0?05). Compared with group IP, the MWT was significantly increased, the TWL was prolonged, and the expression of p?JNK was down?regulated at each time point after establishment of the model in group SP ( P<0?05) , and no significant change was found in the parameters mentioned a?bove in group DMSO ( P>0?05) . Conclusion Spinal JNK signaling pathway is involved in the develop?ment and maintenance of incisional pain in rats.

Aim To study the effect of artesunate on immuno-injured hepatic fibrosis induced by bovine ser-um albumin in rat model and the effect of artesunate on hepatic stellate cells ( HSCs ) proliferation, so as to provide experimental evidence for clinical application of artesunate and the treatment of hepatic fibrosis. Methods The model of immuno-injured hepatic fibro-sis induced by bovine serum albumin was established in Wistar rats. Rats were randomly divided into 5 groups:normal group, model group, low dose of arte-sunate, middle dose of artesunate and high dose of ar-tesunate. Drugs were given to the corresponding thera-peutic groups, and then were continued once a day for two months. Distilled water was given to the rats of normal and model groups according to the same meth-od. Liver tissues were used for measuring the content of collagen, the rat serum activities of albumin( Alb) , alanine aminotransferase ( ALT ) and aspartate amin-otransferase(AST). Liver tissue’ s pathological chan-ges were observed by HE and collagen staining. Isola-ted and cultured rat primary HSCs in the flask for 10 days to make cells activated, MTT assay was used to detect rate of cellular proliferation; concentration of hydroxyproline in supernatant was detected by digestive method; the expression of p53 was investigated by Western blot and RT-PCR. Results Serum levels of Alb in model group were significantly lower ( P <0. 05 ) , and levels of ALT and AST in model group were significantly higher ( P <0. 05 ) compared with normal group. Levels of AST in low, middle and high dose groups(3. 2, 9. 6, 28. 8 mg·kg-1 ) were signifi-cantly lower(P <0. 05) compared with model group, and levels of ALT in high dose groups were significant-ly lower(P<0. 01) compared with model group. The contents of collagen in model groups were significantly higher(P<0. 01) compared with normal group, while the contents of collagen in therapy groups significantly decreased ( P < 0. 05 ) compared with model group. Activated HSCs treated with various concentrations of artesunate (150, 175, 200 μmol·L-1 ) were inhibi-ted on dose and time-effect relationships. Production/secretion of hydroxyproline decreased after HSCs was treated by artesunate for 24 h; the expression of p53 was up-regulated showed by Western blot and RT-PCR in artesunate treated cells. Conclusion Artesunate brings about anti-fibrosis in vitro and in vivo by increas-ing the expression of p53 .
