Abstract? AIM: To investigate changes of anterior chamber parameters after posterior chamber phakic implantable collamer lens ( ICL ) surgery and its correlation with intraocular pressure ( IOP) .?METHODS: This was a retrospective case series study. Seventy four eyes in 43 myopia patients were examined by Allegro Oculyzer anterior segment tomography to obtain the changes of anterior chamber volume ( ACV ) , anterior chamber angle ( ACA) , central anterior chamber depth ( ACD) and vault, meanwhile, to measure the IOP to analyze the correlation with anterior chamber parameters.?RESULTS: Compared with preoperative, ACV, ACA, ACD all decreased apparently ( P <0.01 ) in the postoperative period of 1, 3, and 6mo.ACV, ACA and ACD showed their stability in each period after the surgery.There were changes of vault in 1 and 6mo ( t=27.66, P=0.01).IOP had not altered when compared with the preoperative.This research revealed that IOP had no relation with ACV, ACA, ACD and vault in every phase( all P>0.05).?CONCLUSION:For patients underwent ICL, the anterior chamber parameters all decreased which included ACV, ACA, ACD, and had stabilized since early postoperative period. Correspondingly, IOP was stable and had not correlate with ACV, ACA, ACD and vault, however the long-term observation is still necessary.

To study the preventive effect of sophocarpine (Soc) on dextran sulfate sodium (DSS)-induced colitis in mice, in order to analyze the influence of Soc on toll like receptor 4 (TLR4)/mitogen-activated protein kinases (MAPKs) and janus tyrosine kinase 2 signal transducer and activator of transcription 3 (JAK2/STAT3) signal pathways in mice intestinal tissues. The mice was given 2.5% DSS for 6 days to induce the acute colitis model. The Soc-treated group was intraperitoneally injected with sophocarpine 30 mg · kg(-1) · d(-1) since the day before the experiment to the end. The disease activity index (DAI) was assessed everyday, and the colonic morphology and histological damage were observed with HE staining. The mRNA expressions of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and interleukin-6 (IL-6) were detected by real-time RT-PCR. The changes in key protein kinase p38 mitogen-activated protein kinase (p38MAPK), c-Jun NH2-terminal protein kinase1/2 (JNK1/2), extracellular signal-regulated kinase1/2 (ERK1/2), JAK2, STAT3 in TLR4/MAPKs and JAK2/STAT3 signaling pathways were detected by western blot. The result showed that the model group showed statistical significance in body weight, DAI, colon length and histopathological changes compared with the normal group (P <0.05); however, the Soc-treated group showed significant improvements in the above indexes compared with the model group (P <0.05). TNF-α, IL-1β and IL-6 in the model group was significantly higher than that in the normal group (P <0.05), but lowered in the Soc-treated group to varying degrees (P <0.05). In the normal group, the expressions of TLR4 and the phosphorylation of P38, JNK1/2, JAK2, STAT3 were at low levels; in the model group, the phosphorylation of P38, JNK1/2, JAK2, STAT3 increased; the Soc-treated group showed a decrease in TLR4 expression compared with the model group, with notable declines in the phosphorylation of TLR4, P38, JNK1/2, JAK2, STAT3. These findings indicate that Soc can inhibit TLR4/MAPKs, K2/STAT3 signaling pathway activation, reduce the expression of proinflammatory cytokines TNF-α, IL-1β and IL-6 and relieve inflammatory reactions, so as to effectively prevent experimental colitis.

Objective To dynamically observe the changes of cytokines of splenocytes in mice immunized with recombinant bifidobacteria bifidum (Bb)- Eg95-EgA31 vaccine of Echinococcus grauulosus (Eg). Methods Balb/c mice were vaccinated by 5× 108 colony forming unit(CFU) orally and 5 × 105 CFU intranasally, respectively.Mice were killed on week 0,2,4,6,8,10, 12,14,16, 18 and 20 after immunization, respectively, and spleens were separated for cell culture with the stimulation of EgAg, concanavalin A (ConA) or lipopolysaccharide (LPS). The splenocyte supernatants were collected to determine the levels of interferonγ(IFN-γ), interleukin(IL)-12, tumor necrosis factor α(TNF-o) and IL-l0 using enzyme linked immunosorbent assay(ELISA) with MRS as control. Results In the oral immunization group, the levels of IFN-γ, IL-12, TNF-α and IL-10 showed a significant increase from week 2 to week 8, week 2 to week 8, week 4 and week 6 to week 10 after vaccination, respectively, and reached the highest level on week 4, week 2, week 4 and week 6 after vaccination, respectively;in EgAg stimulation group, the levels of IFN-γ, IL-12, TNF-α and IL-10 were (700.0 ± 115.5), (45.0 ± 5.8), (350.0 ± 57.7), (112.5 ± 14.4)ng/L, respectively, compared with week 0[(35.0 ± 5.8), (12.5 ± 2.9), (190.0 ± 11.6), (25.0 ± 5.8)ng/L, P ＜0.05 or ＜ 0.01] and MRS control group[(37.5 ± 5.0),(13.8 ± 2.5), (195.0 ± 5.8), (27.5 ± 2.9)ng/L, P＜ 0.05or ＜ 0.01]. In the intranasal immunization group, the levels of IFN-γ, IL-12, TNF-α and IL-10 showed an obvious increase from week 2 to week 8, week 2 to week 8, week 2 to week 6 and week 6 to week 16 after vaccination,respectively, and reached the highest level on week 2, week 2, week 4 and week 8 after vaccination, respectively;in EgAg stimulation group, the levels of IFN-γ, IL-12, TNF-α and IL-10 were (700.0 ± 115.5), (55.0 ± 5.8),(275.0 ± 28.9), (140.0 ± 11.6)ng/L, compared with week 0[(35.0 ± 5.8), (12.5 ± 2.9), (190.0 ± 11.6), (25.0 ±5.8)ng/L, P ＜ 0.05 or ＜ 0.01] and MRS control group[(37.5 ± 5.0), (13.8 ± 2.5), (195.0 ± 5.8), (27.5 ± 2.9)ng/L, P ＜ 0.05 or ＜ 0.01]. The cytokine levels in the groups with EgAg, ConA or LPS stimulus were significantly higher than those in the corresponding splenocytes suspension groups(P ＜ 0.05 or ＜ 0.01) , and the cytokine levels in the groups with ConA or LPS stimulus were obviously higher than those in the corresponding groups with EgAg stimulation(P ＜ 0.05 or ＜ 0.01). Conclusion The mixed Th1 and Th2 type response can be induced in mice immunized with the recombinant Bb-Eg95-EgA31 vaccine of Echinococcus granulosus in the early stage of immunization(2 to 6weeks).
