Objective To discuss the feasibility and safety of early enteral nutrition (EN) on treatment of severe acute pancreatitis (SAP) and its influence. Methods The advancement about application of early EN on treatment of SAP in recent years were reviewed. Results In patients with SAP, early EN via catheter placed in the jejunum could protect the integrity of intestinal barrier and reduce infectious complications. But no consensus had been reached about the starting time, ingredient and infusion mode yet. Conclusion Early EN may have positive effects on treatment of SAP, but further researches are still needed.

Vascular cognitive impairment (VCI) is a main type of syndrome from mild cognitive impairment to dementia,which is caused by cerebrovascular risk factors (eg,hypertension, diabetes,hyperlipemia),obvious (cerebral infarction and hemorrhage) or unobvious cerebrovascular disease (leukoaraiosis and chronic cerebral ischemia).Its incidence is increasing,however,its pathogenesis remains uncertain,and effective therapeutic tools are lacking.Therefore,an increasing attention is being paid to all aspects of studies.This article mainly reviews the recent development in research of neuropsychology,imaging,electrophysiology,biology,and gene.

Objective To assess whether dynamic arterial elastance (Eadyn)can be used to predict the reduction of arterial pressure after decreasing norepinephrine (NE) dosage in patients with septic shock.Methods A prospective observational cohort study was conducted.Thirty-two patients with septic shock and mechanical ventilationwere enrolledfrom January 2014 to December 2015 in ICU of Wuxi People's Hospital of Nanjing Medical University.Hemodynamic parameters were recorded by pulse contour cardiac output(PiCCO) monitoring technology before and after decreasing norepinephrine dosage.Eadyn was defined as the ratio of pulse pressure variation (PPV) to stroke volume variation (SVV).Mean arterial pressure (MAP) variation was calculated after decreasing the dose of NE.Response was defined as a ≥ 15％decrease of MAP.AUC was plotted to assess the value of Eadyn in predicting MAP response.Results A total of 32 patients were enrolled in our study,with 13 responding to NE dose decrease where as the other 19 did not.Eadyn was lower in responders than in nonresponders (0.77 ± 0.13 vs 1.09 ± 0.31,P ＜ 0.05).Baseline Eadyn was positively correlated with systolic blood pressure variation,diastolic blood pressure variation,systemic vascular resistance variation and MAP variation (r =0.621,P =0.000;r =0.735,P =0.000;r =0.756,P =0.000;r =0.568,P =0.000 respectively).However,stoke volume variation,baseline level of systemic vascular resistance and NE baseline dose were not correlated with Eadyn baseline value (r =0.264,P =0.076;r =0.078,P =0.545;r =0.002,P =0.987 respectively).Eadyn ≤ 0.97 predicted a decrease of MAP when decreasing NE dose,with an area under the receiver-operating characteristic curve of 0.85.The sensitivity was 100.0％ and specificity was 73.7％.Conclusions In septic shock patients treated with NE,Eadyn is an index to predict the decrease of arterial pressure in response to NE dose reduction.

ObjectiveTo observe the imitation of menopause and the change of spatial cognition in mice administrated with D-galactose and to evaluate the molecular mechanism of estrogen to protect the function of hippocampal neurons.MethodsAdult female C57BL/6 mice were bilateral ovariectomy (OVX) and subcutaneously treated with D-galactose (100 mg/kg). In estrogen replacement therapy(ERT) mice were i.p. administrated with E2 (50 μg/kg). It took 8 weeks to induce the model and treat with ERT. Morris water maze was used test the function of spatial learning and memory. Estrogen and oxidative stress enzymes were detected by kit. 8-oxo-dG was immunohistochemical stained, and the expression of MTH1 in brain hippocampus was detected by Western blotting.ResultsThe level of E2 in blood in model group was one fifth of that in Sham group(P<0-01), and E2 level obviously increased in ERT group; the escape latency significantly prolonged in model group(P<0-01), and obviously shortened in ERT group(P<0-05). SOD and GSH-Px significantly reduced and MDA obviously increased in model group(P<0-05); and approached normal in ERT group. 8-oxo-dG as a DNA oxidative damage marker was obviously increased in the hippocampus of model group. However, the expression of DNA repair protein MTH1 significantly reduced(P<0-05), and both of them returned to normal in ERT group(P<0-05).ConclusionEstrogen can improve the function of spatial cognition in aging mice model by repairing the DNA damage of hippocampal neurons.

AIM:Scopolamine blocks cholinergic transmission and impairs learning and memory in mice．The purpose of this study was to evaluate the memory-improving properties of curcumin on scopolamine-induced memory im-pairment in mice．METHODS：The mice of memory impairment were induced by scopolamine．Step down test and Morris water maze test were used to observe the earning and memory ability in curcumin-treated ice．Biochemical assessments of AChE，MDA，and GSH-Px levels in brains were performed．RESULTS：Oral administration of curcumin ignificantly reduced the numbers of step-down rrors(P<0．05)and prolonged the step-down latency induced by scopolamine(P<0．05)．The escape latency time in mice treated with curcumin Was remarkably educed compared to that in scopolamine group by Morris water maze test(P<0．05)．After the platform was removed，the total time that the mice swam in the tar-get quadrant Was also longer in curcumin group than that in model group(P<0．05)．The data also indicated that curcumin significantly inhibited AChE ctivity(P<0．01)and prevented oxidative stress characterized by the significant reduction in MDA content and the significant increase in GSH-Px activities in the brain(P<0．01)．CONCLUSl0N：Curcumin in-duces cognitive improvement by enhancing the function of cholinergic system and its antioxidant activity．

Objective To compare the clinical outcomes of bone transport technique versus induced membrane technique for treatment of infected bone nonunion.Methods A retrospective study was made on 46 cases of infected bone nonunion admitted from April 2011 to December 2014.They were 33 males and 13 females,aged from 12 to 68 years (mean,45.3 years),involving 40 tibial and 6 femoral fractures.Bone transport technique was used in 37 cases while 9 cases were treated with induced membrane technique.Fracture union and complications were recorded.The function of the affected limb was evaluated at the final follow-up using Johner-Wruhs criteria.Results The 46 cases were followed up for 9 to 18 months (mean,14 months).In the bone transport group,bone union was achieved after a mean duration of 6.5 months (range,from 4 to 11 months) without complications like wound infection or neurovascular lesions.In the induced membrane group,bone union was achieved after a mean duration of 5.8 months (range,from 4 to 11 months) and there was one case of re-infection.According to the Johner-Wruhs score system,34 cases were rated as excellent,9 as good and 3 as fair,with a total excellent and good rate of 93.5％.Bone transport technique led to 28 excellent,4 good and one fair cases in the patients with tibial nonunion,and one excellent,2 good and one fair cases in the patients with femoral nonunion.Induced membrane technique led to 3 excellent,3 good and one fair cases in the patients with tibial nonunion,and 2 excellent cases in the patients with femoral nonunion.Conclusions Both bone transport technique and induced membrane technique are effective for infected bone nonunion.Bone transport technique may be preferred for tibial infected nonunion while induced membrane technique preferred for femoral infected nonunion.
