Objective To summarize the experiences of ultrasonic liposuction in 204 cases, and to analyze the advantages and disadvantages of this technique. Methods The ultrasonic system (SILBERGEE E.U.A. TM ) and the liposuction equipment (HEROULES TM , American) were applied with the tumescent technique in 204 cases. Results Satisfactory rate was 90.69 %. After operation the highest sucked fat quantity was 6 800 ml, and the fewest quantity 250 ml, with an average of 1 907.6 ml for each case. Average volume of sucked fat in each position was 1 005.5 ml, which exceeded that by the traditional method. Advantages of this technique were larger fat quantity, obvious effect, less bleeding and pain, and safety. Disadvantages and complications were rough and uneven surface, accumulation of the liquid, bilateral asymmetry, slow wound healing, subcutaneous ecchymosis and hardening nodule, and even decreased blood pressure. The corresponding processing technique was recommended after liposuction. Conclusion This method is a simple and convenient, safe and reliable technique. It is suggested that multiple times and less portions of liposuction may be of benefit to patients.

Objective To investigate the effects of extractum trametes robiniphila murr combinated with hydroxyurea on proliferation and apoptosis of K562 cells and whether the 2 drugs have synergistic effects,and to detect the antiproliferation and apoptosis ratio of cells in diffe-rent groups were detected.Methods K562 cells were cultured in vitro,and logarithmic phase cells were used for study.MTT-inhibitory test and cell morphological analysis were employed to examine the effects of extractum trametes robiniphila murr alone or in combination with hydroxyurea on proliferation of K562 cells.The effects of extractum trametes robiniphila murr alone or in combinated with hydroxyurea on apoptosis of K562 cells were examined by flow cytometry.The expressions of bcr-abl,bax and bcl-xl mRNA levels were detected by way of reverse transcription polymerase chain reaction(RT-PCR).Results Extractum trametes robiniphila murr could inhibit proliferation and induce apoptosis of K562 cells,and extractum trametes robiniphila murr combinated with hydroxyurea had a synergistic effects on cell prolife-ration and apoptosis.The RT-PCR displayed that either extractum trametes robiniphila murr alone or in combinated with hydroxyurea could down-regulate the expression of bcl-xl mRNA and up-regulate the expression of bax mRNA and the effect of the 2 drugs had a synergistic effect on bcl-xl and bax mRNA expressions.Extractum trametes robiniphila murr alone could also down-regulate the expression of bcr-abl mRNA,but hydroxyurea alone did not show any effect on the expression of bcr-abl mRNA and the 2 drugs had no synergistic effect.Conclusions The effect of extractum trametes robiniphila murr combinated with hydroxyurea on the proliferation and apoptosis of K562 cells has a synergistic effect.The mechanism of antiproliferation and inducing apoptosis of extractum trametes robiniphila murr is probably related to down-regulating the expression of bcl-xl and bcr-abl mRNA and up-regulating the expression of bax mRNA.The synergistic effect of antiproliferation and inducing apoptosis of extractum trametes robiniphila murr combinated with hydroxyurea on K562 cells is probably related to down-regulating the expression of bcl-xl mRNA and up-regulating the expression of bax mRNA.

Objective To explore the secretion of chemokine regulated upon activation normal T cell expressed and secreted(RANTES)influenced by the complex microenvironment in the peritoneal cavity of women with endometriosis and investigate chemotaxis of RANTES on the peritoneal monocytes.Methods The contact and non-contact co-culture systems including three target cells of ectopic tissue were established.The three target cells were endometrial stromal cells(ESC),human peritoneal mesothelial cells(HPMC)and monocytes.After collection of the supernatant of co-culture systems,the levels of RANTES were detected by enzyme linked immunosorbent assay(EUSA).Migration of U937 cell,a monocyte line,was detected by chemotaxis assay.Results ESC,HPMC,and U937 cultured alone secreted slight RANTES,(5.0±0.5),(4.0±0.3),and (254±40)ng/L. Compared with the culture of the target cell alone,the levels of RANTES in each co-culture system increased significantly,with the highest level in the contact culture system of E-H-U(2250±96)ng/L. RANTES secretion of non-contact co-culture of three cells were higher than contact co-culture of two cells(P＜0.01):U/E-H(912±93) vs E-H(50±40)ng/L,H/E-U(1201±93) vs E-U(243±192)ng/L,and E/H-U(1519±96) vs H-U(1251±73)ng/L. ESC,HPMC,and ESC-HPMC co-culture improved significantly migration of U937 cells [ number of cell migration respectively(6.0±0.3),(6.2±0.3),(10.0±0.3)×103,P＜0.01],which could be inhibited efficiently by anti-RANTES neutralizing antibody.Condusion The target cells in the peritoneal cavity of patients with endometriosis promote the secretion of RANTES in autocrine and paracrine manners and migration of monocytes.
