Flexible ureteroscopy techniques have experienced great developments in the past decade, as well as their expanding indications.However, this surgical procedure encountered some discouragement in clinical application for its long learning curve, poor ergonomics, high cost and attrition rate.In recent years, there were a group of advancements in flexible ureteroscopy, including robot-assisted ureteroscopy, dual working channels flexible ureteroscopy, disposable flexible ureteroscopy, rigid ureteroscopy with a deflectable tip and a series of accessory instruments development, which could all make surgery procedures more easily to be done and lower the expenses at the same time.These technical evolutions bring flexible ureteroscopy into a new level in urologic surgeries.

Objective To observe the effects of bone marrow mesenchymal stem cells(BMMSCs) conditioned-medium (B-CM) on apoptosis in cultured cortical neurons after hypoxia-reoxygenation in vitro in rats.Methods BMMSCs were isolated,cultured and expanded,the culture me-dium was substituted by new medium that contain no serum when cells grew to 90% confluence.After cultured for 24 hours,the medium was collected as B-CM.Cortical neurons of mouse cultured for 8 days were divided into three groups:normal control groups,hypoxic group,B-CM disposed groups.Cell viability were detected by 3-(4,5-dimethlthiazd-2-yl)-2,5-diphenyltetra-zoliu bromidel (MTT) methods and the apoptosis of neurons was examined by flow cytometry and telemicroscopy on hypoxia for 0,6 hours and hypoxia-reoxygenation for 24 hours,respectively.Results Compared with control group,hypoxia for 6 hours could decrease cell viability,hypoxia-reoxygenation for 24 hours increased the cell apoptosis ratio remarkably(P

Objective To observe the clinical effect of hyaluronic acid on conception rate of ectopic pregnancy patients who received conservative tubal operation under laparoscopy.Methods 100 patients with ectopic pregnancy received conservative tubal operation under laparoscopy treatment were selected.Hyaluronic acid was used in 50 cases (the treatment group),unused anti blocking preparations for the control group in 50 cases.Then patients were followed up on the tubal patency,and observed pregnancy after 1 year.Results The rate of tubal patency after menstrual clean was 84％ in the treatment group,which was significantly higher than 60％ in the control group(x2 =7.155,P ＜ 0.05).In the treatment group,40 cases were intrauterine pregnancy,4 cases were ectopic pregnancy,6 cases were infertility.The rate of intrauterine pregnancy after 1 year was 80％ in the treatment group,which was significantly higher than 56％ in the control group(x2 =6.65,P ＜ 0.05).Conclusion Hyaluronic acid is effective in preventing tubal adhesion in the ectopic pregnancy patients who received laparoscopic conservative surgery,and can improve the postoperative tubal patency rate and conception rate.

Objective:To analyze effect on the CD154-CD40 signaling pathway and Th1/Th2 polariza-tion by deficient inducible co-stimulator ( ICOS)-ICOS ligand ( ICOSL) signaling in mice infected with Schistosoma japonicum. Methods:ICOSL knockout ( ICOSL-KO) mice and wild-type C57BL/6J mice were used as experimental Schistosomiasis model infected with Schistosoma japonicum. The expressions of CD154 and CD40 on splenocytes and on inflammatory cells around granulomatous infiltration of liver in mice infected with Schistosoma japonicum were analyzed by flow cytometry,immunohistochemical staining, respectively, on the day before infection (0 week) and at the end of 4, 7, 12, 16 and 20 weeks post-infection. The splenocytes of the mice were stimulated with soluble egg antigen( SEA) for 72 hours, then the concentrations of interferon gamma(IFN-γ) and interleukin-4 (IL-4) in the culture supernatants were measured by sandwich enzyme-linked immunosorbent assay ( ELISA) kits. The levels of SEA-specific an-tibodies of IgG and IgG1 and IgG2a were measured in the mice sera by ELISA. The granulomatous pa-thology in the mice liver was dynamically observed by hematoxylin and eosin ( HE ) staining. Results:Compared with the wild-type C57BL/6J mice, the expressions of CD154 on CD4 + T splenocytes [(18. 62 ± 4. 76)% vs. (27. 91 ± 3. 94)%, (22. 44 ± 4. 67)% vs. (40. 86 ± 5. 21)%, (25. 50 ± 6. 81)% vs. (43. 81 ± 8. 41)%, (20. 22 ± 5. 28)% vs. (40. 95 ± 7. 34)%, (17. 87 ± 4. 59)% vs. (33. 16 ± 6. 31)%, all P <0. 01] and of CD40 on CD19 + B splenocytes [(19. 43 ± 3. 26)% vs. (24.37 ±3.59)%, (23. 00 ± 4. 47)% vs. (31. 80 ± 5. 86)%, (24. 46 ± 5. 01)% vs. (35. 85 ± 5. 32)%, (23. 42 ± 4. 69)% vs. (33. 30 ± 6. 14)%, (22. 85 ± 3. 78)% vs. (30. 88 ± 5. 94)%, all P<0 . 05 ] in the ICOSL-KO mice significantly decreased at the end of 4 , 7 , 12 , 16 and 20 weeks post-infection. Moreover, the expressions of CD154[(0. 319 ± 0. 066) vs. (0. 488 ± 0. 086), (0. 389 ± 0. 067) vs.(0.596±0.082),(0.378±0.064) vs.(0.543±0.072),(0.348±0.069) vs.(0.523±0.076), all P<0. 01] and CD40[ (0. 398 ± 0. 066) vs. (0. 546 ± 0. 079), (0. 461 ± 0. 085) vs. (0. 618 ± 0. 076), (0. 453 ± 0. 087) vs. (0. 587 ± 0. 074), (0. 449 ± 0. 065) vs. (0. 565 ± 0. 082), all P <0 . 05 ] on inflammatory cells around granulomatous infiltration in liver from the ICOSL-KO mice were sig-nificantly lower than those of the wild-type C57 BL/6 J mice at the end of 7 , 12 , 16 and 20 weeks post-in-fection. The levels of IFN-γ of the ICOSL-KO mice were significantly higher than those of the wild-type C57BL/6J mice at the end of 4, 7, 12, 16 and 20 weeks post-infection (P <0. 05). However, the levels of IL-4 of the ICOSL-KO mice were significantly lower than those of the wild-type mice ( P <0. 05). Compared with the wild-type C57BL/6J mice, the levels of SEA-specific antibodies of IgG and IgG1 and IgG2a in the sera of the ICOSL-KO mice significantly decreased (P<0. 01). Moreover, The Th2 differentiation index of the ICOSL-KO mice was significantly lower than that of the wild-type mice in post-infection (P<0. 01). Also, the ratio of IgG1/IgG2a of the ICOSL-KO mice were significantly lower than that of the wild-type mice at the end of 7 , 12 and 16 weeks post-infection ( P<0 . 05 ) . And the vo-lume of liver egg granulomas of the ICOSL-KO mice was significantly smaller than that of the wild-type mice ( P <0 . 01 ) . Conclusion: These findings suggest that there is obvious down-regulation in the expressions of CD154 and CD40 and impairment of Th2 immune response in the ICOSL-KO mice infected with Schistosoma japonicum, accompanying with notedly reduced hepatic granulomatous pathology. The ICOS-ICOSL signaling has a regulatory effect on CD154-CD40 signaling pathway, and may play an impor-tant role in the hepatic egg granuloma formation of Schistosomiasis.
