AIM: To investigate the change of myopic choroidal neovascularization treated by ranibizumab and evaluate their value in monitoring the effect of anti-vascular endothelial growth factor ( VEGF) therapy. ·METHODS: The study enrolled 30 patients ( 30 eyes ) diagnosed with myopic choroidal neovascularization. All affected eyes were treated with intravitreal ranibizumab 0. 05mL ( 10mg/mL ). Best corrected visual acuity ( BCVA ) , non-contact tonometer, ophthalmoscope, fundus fluorescein angiograph ( FFA ) and OCTA were evaluated monthly until 6mo. The changes of BCVA and central macular thickness ( CMT) were compared at 1, 3 and 6mo after treatment. ·RESULTS:All patients received an average of 1. 70±0. 65 injections. BCVA was 0. 96 ± 0. 17 ( LogMAR ) before therapy, and BCVA 1, 3 and 6mo after treatment respectively improved by 0. 23 ± 0. 09, 0. 34 ± 0. 07, 0. 38 ± 0. 11. The differences were significant ( t=5. 461, 8. 191, 8. 894; P<0. 05 ). Mean CMT decreased form 281. 07 ± 13. 72μm to 261. 33 ± 13. 13μm, 243. 47 ± 16. 65μm, 234. 73 ± 17. 52μm respectively 1, 3 and 6mo after treatment, showing significant differences (t=12. 007, 13. 360, 9. 531;P<0. 05). OCTA revealed a progressively smaller vascular lesion and reduction in capillary density. · CONCLUSION: Intravitreal ranibizumab for CNV secondary to pathologic myopia is effective and safe;OCTA is a noninvasive and time-saving new technology, and it also is a promising tool for clinicians to make preliminary diagnosis and assess treatment efficacy in the follow-up visits.

Nucleotide-binding oligomerization domain containing protein 2 (NOD2) is a member of intracellular pattern recognition receptor. After being activated, it will induce the release of inflammatory factors through a series of signal cascade transduction, thus playing an important role in the innate immune response. The abnormal NOD2 signaling pathway is involved in the occurrence and development of many diseases, especially the single nucleotide polymorphisms (SNPs) of the NOD2 gene have been identified to be closely associated with autoinflammatory diseases (AIDs). Therefore, inhibitors targeting NOD2 pathway have great potential in the treatment of inflammatory immune diseases. This review presents the recent progress of NOD2 receptor-mediated signal transduction pathways and its regulation mechanisms, the relationship between NOD2 and AIDs, and the inhibitors of NOD2 pathway.

Objective To investigate the differentiation of neuroendocrine component (NEC) in colorectal adenocarcinoma in relation to its significance by comparing the outcome between patients with or without NEC.Methods The paraffin sections from patients with pathologically confirmed colorectal adenocarcinoma were retrospectively collected and screened for those with NEC by morphological examination and immunohistochemistry with neuroendocrine markers.Control patients (n=54) without NEC were selected from colorectal cancer database and 2: 1 matched on the basis of clinical features with NEC positive patients (n=27).Relative analysis was performed between two groups.Results With a median follow-up of 72 months,the 5-year disease free survival was 58.0% (16/27) in NEC positive group and 79.1% (43/54) in control group (P=0.036).Similarly,the 5-year cancer-specific overall survival was significantly lower in NEC positive group than in control group (58.3% versus 81.1%,P=0.037).Cox regression showed that the 5-year cumulative risks of disease recurrence and cancer-caused death in NEC positive patients were 2.38 and 2.41 times higher than those in control patients,respectively.Conclusions NEC appears to bear a poor prognosis in patients with colorectal adenocarcinoma.

OBJECTIVE To evaluate whether the IDO1 inhibitor 1- methyl- L- tryptophan (1- MT) combine calcium influx inhibitor carboxyamidotriazole (CAI) could further enhance the suppression of programmed death 1 (PD-1) in CD8 + T cells and investigate the curative effect of the combined use. METHODS CD8 +T cells were isolated from normal mice spleen by negative selection using magnetic cell separation. The isolated CD8 +T cells were cultured in RPMI 1640 medium containing 10% FBS and 100 U·mL- 1 IL-2 and activated by the addition of anti-CD3 and anti-CD28 (1 g·L- 1 each mabs). CD8 + T cells were pretreated for 48 h with drug and the fluo- 3 as a marker of intracellular calcium concentration was detected by flow cytometry. The calcineurin (CaN) levels were assayed with ELISA in CD8+T cells after 48 h incubation with 10 μm CAI. The nuclear translocations of NFAT and AHR were detected by immunofluorescent staining after 48 h of drug treatment. The expression of PD-1 in CD8+T cells was analyzed by flow cytometry. RESULTS Intracellular fluorescent intensity was markedly debase due to CAI treatment(P<0.01). Meanwhile, the changes of CaN content had a resembled correlation (P<0.01). Immunofluorescence experiment showed that after combination therapy the transfer of NFAT and AHR in nuclear substantially reduced. Flow cytometry revealed that after the combination caused a significant decrease in PD-1 expression in CD8+T cells. CONCLUSION CAI and 1-MT could inhibit markedly the expression of PD-1 in CD8 +T cells by inhibiting the nuclear translocation of NFAT and AHR, respectively and the combination of them has synergetic effect.
