Objective To explore the effects of two lubricants on skin preparation from donor site in patients with skin flap transplantation. Methods According to digit number table, 83 patients undergoing wound repair using modified fascia flap were divided into observation group (n=41) and control group (n=42). The former group were treated with Johnson K-Y Lubricant, while the latter with talcum powder. The two groups were compared in terms of the skin flap quality from donor site, pain degree and number of bacteria before and after transplantation. Results There was no significant difference in bacteria number before and after transplantation in the two groups (P>0.05), but the difference between the groups was significant (P<0.01). The flap preparation quality in the observation group was significantly better than that of control group and the pain degree was significantly lower than that of observation group. Conclusion Johnson K-Y Lubricant can significantly improve flap preparation quality and reduce pain.

AIM: To examine the autoantibody against ? 1-adrenoceptor and its biologic activities during the development of renal hypertension. METHODS: Renal hypertension of rat was achieved by clipped renal artery, the titre of autoantibody to ? 1-adrenoceptor was detected using ELISA immunoassay. Furthermore, the biological offects of these autoantibodies on cultured cardiomyocytes were also examined. RESULTS: After two weeks of clipping renal arteries, both the frequency of occurrence and the titre of autoantibodies to cardiac ? 1-adrenergic receptor were significantly increased as compared with the control of pre-treatment. The increased autoantibodies lasted for several weeks and then automatically decreased gradually to the pre-clipping level at 12 weeks. The biological effects of these autoantibodies displayed an "agonistic-like" activities on the beating frequency of cultured neonatal cardiomyocytes. CONCLUSION: Autoantibodies against ? 1-adrenoceptor may play a role in the elevation of peripheral vascular resistance and in the development of cardiac hypertrophy in rats with renal hypertension.
