Gadd45a, a p53 and BRCA1-regulated growth arrest and DNA damage gene, plays important roles in suppressing cell transformation and tumor malignancy. Gadd45a maintains the genomic stability through inhibiting the cell growth and promoting the DNA repair etc, by which it suppresses the tumor development. Additionally, Gadd45a is involved in some important signaling pathway, contributing to its function in tumor suppressing.

Objective To observe the influence state of asarone injection for the pulmonary surfactant proteins and oxygen supply state of newborns with pneumonia. Methods 72 newborns with pneumonia were selected as the study object, and they were randomly divided into control group (36 cases) and observation group (36 cases), the control group were treated with conventional treatment of pneumonia, the observation group were treated with asarone injection on the treatment method of control group, then the pulmonary surfactant protein indexes, oxygenation function indexes and blood gas analysis of two groups before and after the treatment were respectively detected and compared. Results The pulmonary surfactant protein indexes, oxygenation function indexes and blood gas analysis of two groups before the treatment all had no significant differences, while the pulmonary surfactant protein indexes, oxygenation function indexes and blood gas analysis of observation group at first, second and fifth day after the treatment were all significantly better than those of control group, all P<0.05, there were all significant differences. Conclusion The asarone injection can significantly improve the pulmonary surfactant proteins and oxygen supply of newborns with pneumonia, so its application value in the treatment of newborns with pneumonia is higher.

Objective To research the mechanism or pathway through which Substance P(SP) inhibits r-aminobutyric acid(GABA) activated currents in bullfrog dorsal root ganglion(DRG) neurons.Method The experiment was conducted on freshly isolated bullfrog dorsal root ganglion neurons using a whole-cell patch-clamp technique.Results SP could caused a slow inward current when SP was applied to DRG neurons;SP could inhibits GABA-activated currents;The inhibition could be reduced largely when protein kinase C(PKC) inhibiter,1-(5-isoquinolinesulphorry)-2-methylpiperazine(H-7), was dialyzed in cell body.Conclusion The SP ton inhibit GABA-activated currents through protein kinase C.

Objective To explore the clinical features of diabetic macular edema (DME) with optical coherence tomography (OCT) and correlation with visual function. Methods Forty-nine eyes from 40 patients with DME (DME group) and 31 eyes from 31 patients without DME (control group) were examined with OCT,pattern reversal visual evoked potentials (P-VEP),macular perimetry. According to proliferative diabetic retinopathy (PDR), 49 eyes with DME were divided into group A (without PDR, 30eyes) and group B (with PDR, 19 eyes). Results The retinal macular thickness of central fovea in DME group [(299.25±63.87)μm] was more than that in contol group [(204.35 ± 37.94)μm], visual acuity and macular visual field in DME group were significantly different than those in control group, respectively (P ＜ 0.05). The retinal macular thickness of central fovea,visual acuity and visual field were no significant differences between group A and group B (P＞0.05). OCT macular thickness and visual correlation coefficient was -0.437(P＜ 0.05 ); OCT macular thickness and mean defect correlation coefficient was 0.441(P ＜ 0.05). Conclusions OCT can provide a useful tool for monitoring the occurrence and development of DME, can assess the response to treatment. With increasing of the macular retinal thickness, the visual acuity and macular visual field of visual function are more damaged.
