Objective To explore the comprehensive approach of rhinoplasty using autologous costal cartilage,and to observe the outcome and summarize the possible complications.Methods A 6-7 cm long costal cartilage was taken out mostly from the 6th or 7th rib and then divided into several parts and shapes.A lancet shaped piece was used for dorsal augmentation,several cartilage bars for collumellar elevation and nasal tip elongation.Comprehensive structural rhinoplasty was then done with open rhinoplasty incision.Results 52 patients were treated with this method and satisfying aesthetic contouring of the nasal tip and dorsum was achieved.Among these patients,no such complications as implant extrution or dislocation,cartilage distortion,pneumothorax,hemothorax,infection or hemotoma were observed.The scar on the donor site was not obvius.Conclusions Costal cartilage can meet the demands of patients who consider prosthesis as an unacceptable option.For secondary revision rhinoplasties,costal cartilage provides sufficient materials to ensure a promising outcome with lower risk of infection and other complications.

Objective To study the diterpenoids possessed immunosuppressive activity from Tripterygium hypoglaucum. Methods The chemical constituents were isolated from the CHCl3 extracts of T. hypoglaucum by repeated column chromatography, including silica gel, Sephadex LH-20, and preparative HPLC. Their structures were elucidated on the basis of spectroscopic studies. The immunosuppressive activity of these compounds was tested using the lymphocyte transformation test. Results Compounds Ⅰ-Ⅵ were identified as triptobenzene H (Ⅰ), triptoquinone A (Ⅱ), triptoquinone B (Ⅲ), triptoquinone H (Ⅳ), triptonediol (Ⅴ), triptonoterpene (Ⅵ). Conclusion Compound Ⅰ-Ⅲ are isolated from this medicinal plant for the first time and all the compounds show the significant immunosuppressive activity.

Objective To explore the comprehensive approach of rhinoplasty using autologous costal cartilage and e-PTFE,and to observe the outcome and possible complications.Methods A 3-4 cm long costal cartilage was taken out mostly from the 6th or 7th rib and then divided into several parts and shapes.Structural reconstruction of the nasal tip was then done with these costal cartilage parts.Radix augmentation was conducted with e-PTFE.Results From Jan.2013 to Sept.2014,48 patients were treated with this method,all females,aged 22-35 years.36 of them had received rhinoplasty before,12 of them received none.Satisfying aesthetic contouring of the nasal tip and dorsum had been achieved in 45 patients.Deviation of the collumella and nostril asymmetry were found in 3 patients.Among all patients,no such complications as pneumothorax,hemothorax,infection,or hemotoma were observed.The scar on the donor site was not obvious.Conclusions Costal cartilage is sufficient,supportive and easily shapable,when applied to the structural reconstruction of the nasal tip,which can meet the demands of patients who prefer more outstanding and delicate nasal tip contouring.

Objective To investigate influence of chromosomal translocations on early embryo development and to evaluate the efficacy and feasibility of preimplantation genetic diagnosis (PGD)techniques through clinical analysis on PGD cycles. Methods Embryo development, efficacy of PGD and clinical outcome of 100 cycles were studied retrospectively, including 23 cycles with Robertsonian translocations, 19 cycles with reciprocal translocations, and 58 cycles for α-Thalassaemia. Results Among 354 embryos biopsied by PGD for translocations, 321 (90. 7% ) presented fluorescence in situ hybridization (FISH) results. The rate of normal/balanced embryos in the Robertsonian translocation was 38. 3% (64/167),which was significantly higher than 20. 8% (32/154) in the reciprocal translocation group. Amplification was achieved in 443 blastomeres from 537 embryos in Thalassaemia group, which given to an amplification efficiency rate of 82. 5% ( 443/537 ). Totally, 140 normal homozygous, 112 heterozygotes and 155 affected homozygous embryos were identified, while 36 embryos had uncertain result. The successful diagnostic rate was 75.8% (407/537). After 3 days in the translocation groups, the rate of normal and/or balanced translocations in biopsed embryos with ≥7 cells was 34. 4% (77/224), which was significantly higher than 19. 6% ( 19/97 ) of biopsed embryos with ＜ 7 cells. After 4 days, the compaction rate in normal/balanced embryos was 59.4% ( 57/96 ), which was significantly higher than 34. 2% ( 77/225 ) in imbalanced embryos significantly. Seventy-five embryos transferred in 37 cycles with translocations group led to clinical pregnancy rate of 27.0% (10/37), and 170 embryos transferred in 58 cycles with Thalassaemia got a clinical pregnancy rate of 43. 1% ( 25/58 ) . Conclusions PGD can provide management efficiently for both chromosome translocations and Thalassaemia. Translocations might have slightly negative impact on embryo development before implantation.

Objective To compare the diagnostic efficiency between blastomere preimplantation genetic diagnosis (PGD) and polar body PGD for chromosomal translocation carriers. Methods Group A had 8 cycles using whole painting probes for the first polar body diagnosis, while group B had 29 cycles using two subtelomeric probes and one centromeric probe for the blastomere diagnosis. Results The fertilization rate of group A was significantly lower than group B [66. 1% (72/109) vs 85.2% (304/357) , P < 0.05]. There was no significant difference in the successful biopsy rate between two groups. However, group A had a significantly higher loss rate during fixation and higher no signal rate after fluorescence in situ hybridization [ FISH, 9. 6% (12/104) vs 1.6% (4/252), 11.2% (10/89) vs 3.0% (7/233) ]. Totally, the diagnostic efficiency in group A (72. 5% ,79/109 ) was significantly lower than that in group B( 89. 8%, 230/256, P < 0. 05 ). Although both the clinical pregnancy rate( 3/7 ) and implantation rate( 22. 2% ,4/18 ) of group A were higher, the differences were not statistically significant ( P > 0.05 ). Conclusion Both methods can be used efficiently in the PGD for chromosomal translocation carriers. Blastomere PGD has a higher diagnostic rate.

Objective:To study the difference in anti-hepatic fiborsis components between pre-and post-processed Trionyx Sinensis Carapace to guide the clinical application of Trionyx Sinensis Carapace. Methods:SDS-PAGE gel electrophoresis was used to compare the constituents in pre-and post-processed Trionyx Sinensis Carapace, and the inhibitory effect on the proliferation of HSC-T6 was deter-mined by MTT. Results:The processed Trionyx Sinensis Carapace had much more components than the crude Trionyx Sinensis Cara-pace,and the relative molecular mass in the first-level band decreased resulting in the generation of micromolecular polypeptides. Both pre-and post-processed Trionyx Sinensis Carapace had anti-hepatic fibrosis, while the vinegar-processed Trionyx Sinensis was more ef-fective. Conclusion:The difference in the active components in pre- and post-processed Trionyx Sinensis Carapace is obvious, which provides foundation for the clinical application and further researches.
