BACKGROUND: Appropriate anastomosis materials can improve success rate of trachea and bronchus reconstruction.Common domestic suture materials include silk suture, dacron and synthesized absorbable suture. However, the suture with best effects in preventing and lightening scar granulation hyperplasia and luminal stenosis remains Uncertain.OBJECTIVE: To compare the influence of three kinds of suture materials on histopathological changes of anastomotic stoma and transforming growth factor-β_1 (TGF-β_1) expression in rabbits following tracheotomy.DESIGN, TIME AND SETTING: A randomized, controlled animal experiment and histopathological observation were performed at the Animal Experimental Department, Nanhua University from September 2005 to October 2006.MATERIALS: Artificial absorbable suture was purchased from Brazil Johnson & Johnson Professional Products; silk suture and dacron were purchased from Hangzhou Fuyang Medical Suture Factory and Hangzhou Huawei Medical Products Co., Ltd.METHODS: A total of 36 New Zealand healthy adult rabbits, regardless of gender, weighing 1.6-2.0 kg, were randomly divided into silk, dacron and artificial absorbable suture groups with 12 animals in each group. The end-to-end anastomosis following tracheotomy was performed using silk, dacron and artificial absorbable suture, respectively.MAIN OUTCOME MEASURES: The pathological changes and TGF-β_1 level around the sutures 1, 2, 4 weeks post operation were observed.RESULTS: A total of 36 rats were included in final analysis. There were no difference in anastomotic healing between three groups 1 and 2 weeks postoperatively, with a great amount of inflammatory cell infiltration, mainly neutrophil, around the sutures.Moreover, bleeding in the focus and foreign body grannuloma were found. At 4 weeks postoperatively, foreign body grannuloma formed accompanied with obvious firboplasia in silk and dacron groups, and the sutures in the artificial absorbable suture group were absorbed. Compared with 1 and 2 weeks postoperatively, the expression of TGF-β_1 was slightly decreased in silk and dacron groups at 4 weeks (P > 0.05), but the absorbable suture group significantly decreased (P < 0.05).CONCLUSION: Of three kinds of suture materials, artificial absorbable suture exhibited good histocompatibility, effectively reducing inflammatory reaction and benefiting the prevention and lightening of formation of pathological scar after tracheal surgery.

The mechanism is mainly through regulating intestinal flora, increasing insulin content, lowering blood sugar, lowering blood lipids, improving glucose tolerance, and improving gluconeogenesis, antioxidant, inhibit cell apoptosis, etc. play the role of preventing and treating T2DM in multiple links and multiple targets.

Objective To determine the expression of Caspase 8 and phospho-Akt(p-Akt)in condyloma acuminatum(CA)lesions, and to evaluate their significance. Methods Skin lesion samples were collected from 30 patients with CA, cancer tissue samples from 20 with cervical cancer, and normal skin samples from 20 healthy controls. All the samples were subjected to paraffin embedding. An immunohistochemical study was conducted to determine the expression and distribution of Caspase 8 and p-Akt in the above samples. Results The expression rate of Caspase 8 was significantly lower in CA lesions (23.33%)than in normal skin samples(90%, P < 0.01)and cervical cancer lesions(80%, P < 0.001). Moreover, the expression rate of p-Akt in CA lesions(93.33%)was significantly higher than that in the normal skin samples(90%, P<0.001), but lower than that in the cervical cancer lesions(95%, P<0.001). No significant correlations were observed between the expression of Caspase 8 and p-Akt in either CA lesions or normal skin samples. However, the expression of Caspase 8 was positively correlated with the expression of p-Akt in cervical cancer lesions(r=0.369, P<0.05). Conclusion Both suppressed apoptosis initiation of Caspase 8 and anti-apoptotic effect of p-Akt may be involved in the occurrence and development of CA.

Objective To investigate the expression and significance of TLR4, TLR9 and DC-SIGN in primary and recurrent condyloma acuminatum (CA) lesions. Methods An immunohistochemical method using streptavidin-peroxidase (SP) was performed to detect the expressions and distribution of TLR4, TLR9 and DC-SIGN in tissue specimens obtained from the recurrent CA lesions of 30 patients, primary CA lesions of 30 patients, and from the foreskin of 20 normal human controls. Results The expression levels of TLR4, TLR9 and DC-SIGN in primary and recurrent CA lesions were significantly higher than those in normal control tissue (all P < 0.001), and the cells expressing TLR4, TLR9 or DC-SIGN were mainly located in the basal and spinous layer in CA lesions. There was no significant difference in the expressions of TLR4, TLR9 or DC-SIGN between primary and recurrent CA lesions (all P> 0.05). A positive correlation was found between the expression of TLR4, TLR9 and DC-SIGN in CA lesions. Conclusion The overexpression of TLR4, TLR9 and DC-SIGN probably plays an important role in the occurrence and recurrence of CA.
