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 any therapeutic effect of pulsed electromagnetic fields (PEMFs) on bone loss in spinal cord injury (SCI) patients.Methods Fifty-five patients with SCI were divided into two groups randomly.The twenty-six patients in the control group (group B) were given only routine rehabilitation treatment; the twenty-six patients in the treatment group (group A) received PEMF therapy in addition.Results After 12 weeks of treatment,the average bone mineral density (BMD) of the proximal femur (including total,neck,Wards,inter,troch) in group A was significantly higher than in group B.The levels of bone-gamma-carboxyglutamic acid containing protein (BGP) and 1,25 (OH)2D3 in group A increased significantly,while they decreased in group B.Urine-pyridinium/crealinine (U-Pyd/Cr) levels in group A decreased significantly,while in group B they were higher than before.There were statistically significant differences between the two groups.Conclusion PEMF treatment can effectively retard bone loss in SCI patients.It has good preventive and curative effects on osteoporosis after SCI.

Objective To analyze the effect of inducible costmulator (ICOS)/inducible costmulator ligand (ICOSL) signaling pathway on hepatic fibrosis in mice infected with Schistosoma japonicum.Methods Seventy-eight ICOSL knockout (ICOSL-KO) mice and 77 wild type C57BL/6J mice were used as experimental schistosomiasis model infected with Schistosoma japonicum.The sera of mice were collected on the day before infection (0 week),and at 4,7,12,16 and 20 weeks post infection.Then,the concentrations of hyaluronic acid (HA) and hydroxyproline (HYP) in mice sera were measured by sandwich enzyme linked immunosorbent assay (ELISA) kits.The expressions of transforming growth factor β1 (TGF-β1),α-smooth muscle actin (a-SMA) and Collagen-Ⅰ in livers from ICOSL-KO/wild type mice were assessed by immunohistochemical staining.The granulomatous pathology and fibrosis level in mice liver were dynamically observed by hematoxylin and eosin (HE) staining and Masson's staining,respectively.The difference between groups was detected by t test or x2 test when appropriate.Results After infection with Schistosoma japonicum,the levels of HA and HYP were gradually increased.In ICOSL-KO mice,the levels of HA at 7,12,16 and 20 weeks post infection were all significantly lower than those in wild type mice [(161.32±15.44) vs (186.01±21.24) ng/mL,t=2.528 2,P＜0.05; (166.73±18.18) vs (231.39±20.12) ng/mL,t=4.342 4,P＜0.05; (193.58±21.06) vs (252.51±25.29) ng/mL,t=4.003 9,P＜0.05; (253.98±24.53) vs (310.88±23.86) ng/mL,t=3.718 0,P＜0.05].Similarly,HYP levels in ICOSL-KO mice at 12,16 and 20 weeks post infection were all significantly lower than those in wild type mice (all P＜0.05).Immunohistochemical staining showed that TGF-β1,α-SMA and Collagen-Ⅰ expressions in liver of ICOSL-KO mice from 7 to 20 weeks post infection were all significantly lower than those of wild type mice (all P＜0.05).HE staining showed,the volume of liver egg granulomas of ICOSL-KO mice was significantly smaller than that of wild type C57BL/6J mice (P＜0.01).Furthermore,Masson's staining showed that the level of hepatic fibrosis in ICOSL-KO mice was lower than that in wild type mice and the fibrosis scores were statistically different between two groups (all P＜0.05).The mortality rate of the wilde type C57BL/6J mice was higher than that of ICOSL-KO mice.After 20 weeks of infection,the difference was statistically significant (55.84 ％ vs 37.18 ％,x2 =5.427,P＜0.05).Conclusions The degree of hepatic fibrosis and related indicators are obviously down-regulated in ICOSL-KO mice infected with Schistosoma japonicum.These findings suggest that ICOS/ICOSL signaling pathway has an important impact on the process of hepatic fibrosis caused by Schistosoma japonicum.

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.
