Objective To explore the impact of different hemoglobin on postoperative cognitive functions in female patients underwent laparoscopic surgery. Methods 215 female patients who were underwent laparoscopic total hysterectomy or laparoscopic myomectomy from January 2016 to December 2016 in our hospital were selected. The patients were divided into 3 groups according to their hemoglobin:Group N with normal hemoglobin ,Group A with hemoglobin concentration of 9 ~ 11 g/L ,and Group B with hemoglobin concentration of 6 ~ 9 g/L. Same anesthesia and recovery plan were performed in all patients. Basic and operative information were recorded. The score of MoCA on the day before surgry ,the day after surgry ,3 days after surgry and 30 days after surgry were recorded. Blood samples were collected on the day before surgry and the day after surgry for the determina-tion of serum S-100β protein and IL-6 concentrations. Results No significant difference was found in basic and operative information among three groups. The recovery time was much longer in Group B than that in Group N. No difference were found among three group in the score of MoCA on the day before surgry and 30 days after surgry ,while the score in the day after surgry and 3 days after surgry were lower in Group B com-pared with Group N. The incidence of POCD were higher in Group B compared with Group N. Compared with the day before surgry ,the concentration of serum S-100β protein and IL-6 were much higher. And compared with Group N ,the concentration of serum S-100β protein was higher in Group A and B in the day after surgry , while IL-6 was higher in Group B. The concentration of serum S-100βprotein and IL-6 were much higher in Group B compared with Group A in the day after surgry. Conclusion Female patients with hemoglobin concen-tration of 6 ~ 9 g/L are susceptible to POCD ,which might be contributed by operative central nerve system damage induced by excessive inflammation.

Objective To observe the blood perfusion of optic nerve and macular areas and investigate its relationship with visual field defect in nonarteritic anterior ischemic optic neuropathy (NAION). Methods Twelve consecutive unilateral NAION patients (course of disease <3 months) and 12 healthy Chinese adults were enrolled in the study. The affected eyes and fellow eyes from 12 NAION patients were defined as group A and group B; 12 eyes from 12 healthy adults were defined as group C. Best corrected visual acuity (BCVA), intraocular pressure (IOP), indirect ophthalmoscope and computer optometry were performed on all of the three groups of patients. Visual field (VF) and optical coherence tomography (OCT) were performed on NAION patients. Logarithm of the minimum angle of resolution (logMAR) was used to calculate visual acuity. Compared to group B, logMAR BCVA, mean deviation (MD) and pattern standard deviation (PSD) in group A were significant decreased (t=3.278, -4.909, 4.130, P<0.05). There was no significant difference in spherical equivalent, IOP, peripapillary retinal nerve fibre layer (pRNFL) between group A and group B (t=0.000, 0.890, 1.215; P>0.05). OCT angiography (OCTA) was used to measure the flow area (FA) at optic disc, flow area at radial peripapillary capillaries (RCFA) and FA, non-perfusion area (NFA), parafoveal vessel density (PVD) and parafoveal vascular index (PVI) in macular area. Pearson correlations between the deficiency of optic blood flow and visual field were analyzed. Results The differences of FA at optic disc and peripapillary RCFA among 3 groups were significant (F=4.162, 3.357; P<0.050). Compared to group B (t=-5.822, -7.467; P<0.001) and C (t=9.435, 4.615, P<0.05), FA at optic disc and peripapillary RCFA in group A was significantly reduced. There is several NAION showed quadrantal FA decreased in optic nerve. However, there was no significant difference in optic disc FA and peripapillar RCFA between group B and C (F=0.004, 0.030; P>0.050). There was no differences of FA, NFA, PVD and PVI among 3 groups (F=0.488, 1.107, 0.493, 1.086, 1.098, 0.093, 1.093, 1.221; P>0.05). Positive correlation between optic disc FA, peripapillary RCFA and MD (r=0.542, 0.585;P<0.05) were observed. However, there was no significant correlation between optic disc FA, peripapillary RCFA and PSD (r=-0.404, -0.430; P>0.05), and negatively correlated to BCVA (r=-0.617, -0.596; P<0.05). PRNFL was negatively correlated to optic disc FA (r=-0.643, P<0.05), but not correlated to peripapillary RCFA (r=-0.377, P>0.05). Conclusions The optic disc blood flow reduced in affected eyes of unilateral NAION whose disease course was less than 3 months, while the macular perfusion was normal. There was a positive correlation between optic disc flow and visual field.
