Objettive To evaluate the effect of taking vitrectomy on the patients who suffer from polypoidal choroidal vasculopathy (PCV) combined with vitreous hemorrhage (VH),observe the natural consequence of PCV combined with VH and analyze the factors that affected the visual prognosis.Methods The clinical data of 20 patients with PCV combined with VH who performed vitrectomy were analyzed retrospectively from January 2009 to September 2012.Best corrected visual acuity (BCVA) was compared before and after operation,and explored the factors that affected the visual prognosis.Results Patients were followed up 6-18 (13 ± 2) months.At the last follow-up,BCVA was improved and better than 0.05 in 11eyes.There was significant difference in BCVA between before operation (2.91 ±0.52) and 2 weeks after operation (1.52 ±0.51)(P =0.003).The natural factors between visual acuity improved patients and non-improved patients were compared,follow-up treatment and the condition of macular was the independent factor that affected the visual prognosis (P =0.009,0.034).There was significant difference in BCVA of 6months after operation between patients with follow-up treatment (photedynamic therapy or transpupillary thermotherapy,10 cases) and patients without follow-up treatment (10 cases)(0.77 ± 0.51 vs.1.43 ± 0.64)(P =0.035).Conclusions Vitrectomy can significantly improve the visual acuity of PCV combined with VH.It will get better visual acuity,if has photodynamic therapy or transpupillary thermotherapy postoperatively.

Objective To investigate the effects of crude extract of Capparis spinosa L. fruit alka-loids (CSFA) on the maturation of murine bone marrow-derived dendritic cells (DCs). Methods CSFA was prepared and the contents were determined by high performance liquid chromatography. DCs were trea-ted with different doses (1, 2, 3 mg/ml) of CSFA. The viability of DCs, the expression of surface mole-cules and the ability of phagocytosis were detected by flow cytometry. The secretion of cytokines was meas-ured by ELISA. Western blot assay was performed to analyze the activation of key molecules in mitogen-acti-vated protein kinases ( MAPK) and nuclear factor-kappa B ( NF-κB) signaling pathways. Results The re-sults showed that CSFA alone had no significant influence on the expression of surface molecules and cyto-kines in DCs. However, it significantly decreased the expression of CD40, CD80, CD86 and MHC Ⅱ as well as the secretion of IL-12p40 and TNF-αthat were induced by lipopolysaccharides (LPS), but increased IL-10 secretion and the ability of phagocytosis after treating DCs with both CSFA and LPS. Further, the phosphorylation of p38, extracellular signal-regulated kinase (ERK) and c-Jun NH2-terminal kinase (JNK) and the nuclear translocation of NF-κBp65 induced by LPS were inhibited by CSFA. Conclusion CSFA could inhibit the maturation of DCs and the secretion of pro-inflammatory cytokines induced by LPS while in-creasing the secretion of the anti-inflammatory cytokine IL-10 and the ability of phagocytosis, which might in-volve MAPK and NF-κB signaling pathways. This study suggests that CSFA could be used as a potential im-munosuppressant.

Ferroptosis is a novel iron-dependent mode of programmed cell death characterized by iron deposition and accumulation of lipid peroxidation. More and more studies have found that ferroptosis is closely related to the pathogenesis of type 2 diabetes mellitus （T2DM）. The yin-fire theory is an important part of LI Gao's spleen-stomach theory， and it is believed that qi-fire imblance and yin-fire internal generation is the main pathogenesis of T2DM. Abnormal iron metabolism may be an important prerequisite for T2DM yin-fire internal generation， while oxidative stress is the specific manifestation of T2DM qi-fire imbalance. Reactive oxygen species （ROS） is the end product of qi-fire imbalance， and lipid peroxide is the pathological products of T2DM yin-fire internal generation. This study intends to explore the pathological mechanism of qi-fire imbalance and yin-fire internal generation from the perspectives of iron metabolism， oxidative stress and lipid peroxidation， enriching the modern connotation of yin-fire theory， and benefiting traditional Chinese medicine to target against ferroptosis， and prevent and treat T2DM precisely.
