Photolysis and ozonolysis of (iso) desmosine-containing crosslinked peptides from porcine aorta elastin

This report describes the use of photolysis and ozonolysis as a means of achieving complete cleavage of the pyridinium ring of (iso)desmosine in crosslinked elastin peptides. Although photolysis leads to the opening of the ring with concomitant formation of lysine, the peptide chains remain attached. Subsequent ozonolysis is able to completely achieve the cleavage of the rest of the ring skeleton, thus leading to the separation of the peptide chains. Formation of new amino acids, i.e. α-aminoadipic and glutamic acids, is emphasized. Localization of these amino acids within the released peptides should be of help in structural investigations on the crosslinking zones involving either isodesmosine or desmosine. However, other amino acids such as tyrosine and phenylalanine are sensitive to this procedure and side reactions occur which are responsible for peptide bond cleavage with the formation of breakdown products.

36例胰腺浆液性囊腺瘤的临床分析

目的：探讨胰腺浆液性囊腺瘤的诊断和治疗。方法：对1998年6月至2006年9月瑞金医院收治的36例病理诊断为胰腺浆液性囊腺瘤的临床资料进行回顾性分析。结果：胰腺浆液性囊腺瘤好发于中老年女性,多见于胰腺头颈部,无特征性临床表现。B超和CT诊断囊性肿瘤的正确率分别为69%（25/36）和94%（34/36）。CT对于囊腺瘤的诊断正确率为80%（29/36）,对浆液性囊腺瘤的诊断正确率为61%（22/36）。在不能排除或考虑实性假乳头状瘤的病人中MRI对于囊腺瘤的诊断正确率80%（4/5）。本组35例行手术治疗,其中7例行胰十二指肠切除;11例行胰腺节段切除;12例行胰体尾切除;5例行局部切除,1例行剖腹探查活组织检查。10例术后出现并发症,包括胰瘘、内出血、幽门梗阻、胰腺假性囊肿合并肠瘘病人及不同程度的胸腔积液。1例因内出血死亡。本组3例失访,32例获随访,除2例因其它疾病死亡,其余均健在,术后无复发。结论：CT和MRI,结合肿瘤学指标和临床病理特征可大大提高浆液性囊腺瘤的术前诊断率。浆液性囊腺瘤是一种良性的肿瘤,但手术治疗并发症较多。大多数浆液性囊腺瘤可考虑随访;有症状的胰腺浆液性囊腺瘤,或与黏液性囊性肿瘤不能鉴别者,应手术治疗。

Effects of seawater immersion combined with open abdominal injury on the expression of NF-κB,and IκBαof small intestine in rats

Objective To observe effects of seawater immersion combined with open abdominal injury on the expression of NF-κB,and IκBαas well as the change pattern in rats. Methods Ninety-one Wistar rats were randomly divided into 3 groups: the control group (n =7), the open abdominal injury group(n =42) and open abdominal injury combined with 1-hour seawater immersion group ( n =42). The expression of NF-κB,andIκBαin small intestine tissues was measured by Western blot and statistical analyses were also made in the study. Results The expression of NF-κB,in the seawater immersion combined with open abdominal injury group increased significantly 3 hours after injury, when compared with that of the open abdominal injury group(P<0. 05), whereas the expression of NF-κB, of the pure injury group was slightly lower than that of the control group, but no statistical differences could be seen between them(P>0.05). The change pattern in the expression of IκBαwas quite the opposite to that of NF-κB. Conclusions NF-κB seemed to be rapidly and persistently involved in the whole inflammatory response to trauma induced by opened abdominal injury and seawater immersion, when a comparison was made with the pure open abdominal injury group. Injuries for the rats in the open abdominal injury combined with seawater immersion group were serious, and the feedback mechanism for NF-κB was not established for quite a long time.
