Objective To compare the efficacy，safety and prognosis of super-selective superior rectal artery branch embolization(SRAE)and procedure for prolapse and hemorrhoids(PPH). Methods A retrospective analysis was performed on 37 cases of SRAE and 60 cases of PPH in our hospital from June 2017 to December 2018.Patients were followed up for 12 months and compared the operation time，blood volume，hemoglobin index，hospitalization time，hospitalization cost，incision infection and bleeding， postoperative pain and fever，anal canal stenosis，constipation，antibiotic use，and disease recurrence. Results Patients in the SRAE group were older(P=0.009)，with more cases of hypertension，diabetes and cardiac insufficiency(P<0.001). The SARE group had shorter operation time，less intraoperative blood loss，less postoperative pain，less bleeding，less postoperative fever，less antibiotics after surgery，no postoperative anal stenosis，and shorter hospital stay(P<0.000 1)，but hospitalization costs were higher than PPH group(P<0.000 1).There was no difference in the incidence of postoperative constipation(P= 0.067) between the two groups and preoperative and follow-up hemoglobin index(P=0.154；P=0.278). The postoperative delirium recurrence or reoperation was used as the combined end point. Kaplan-Meier curve combined with Log-rank test showed no significant difference between the two groups(P=0.56). Conclusion SRAE is safe and reliable，and it has obvious advantages over PPH in reducing complications such as bleeding and postoperative pain.Compared with conventional minimally invasive surgery，the longterm effect of SRAE is not ideal，but it provides a beneficial option，especially for high-risk patients.

[Objectives] This study aimed to evaluate the effects of rumen-protected arginine(RP-Arg) and N-carbamylglutamate(NCG) supplementation on development of maternal and fetal placenta in nutrient restriction Hu sheep during pregnancy.[Methods] From 35 to 110 days of pregnancy, 32 Hu ewes carrying twin fetues were randomly divided into 4 groups, a control group(CG, n=8, 100% NRC requirements for pregnant sheep), a underfed group(RG, n=8, fed 50% NRC requirements, which included 50% mineral-vitamin mixture), and 2 treatment groups(ARG and NCG, n=8, fed 50% NRC requirements supplemented with 20 g·d-1 RP-Arg or 5 g·d-1 NCG, which included 50% mineral-vitamin mixture). At 110 days of pregnancy, fetal umbilical venous plasma, maternal placenta(caruncle) and fetal placenta(cotyledons) were collected. The study evaluated the concentration of metabolites in umbilical venous plasma, the expression of this growth factor family and mTOR signaling pathway's intermediates(mTOR, p70S6K, 4EBP1) in caruncle and cotyledons.[Results] The results showed that the ratio of fetal body weights to placental weight decreased in RG group compared with CG group; however, the placental weights showed no differences among CG, ARG and NCG groups. The results showed that the ratio of fetal body weights to placental weight decreased in RG group compared with CG group; however, the placental weight, weight of cotyledons and caruncula showed no differences among CG, ARG and NCG groups. The mRNA expressions of VEGFA, VEGFR-1, PLGF1, Ang-1, and Ang-2 were not significant in cotyledons and caruncula of four groups. Significantly increased mRNA expression of VEGFR-2 was detected in RG group compared to CG, ARG, and NCG groups, but there was decreased Tie-2 mRNA expression in RG group. In RG group, mTOR signaling was inhibited, as determined by increased p70S6K and 4EBP1 mRNA expressions, and increased p70S6K, 4EBP1, and p-p70S6K proteins expression.[Conclusions] The data provide important insight into the maternal nutrition levels altering developmental programming of cotyledons and caruncula. Dietary RP-Arg and NCG supplementation to underfed ewes during pregnancy could promote the growth and development of cotyledons and caruncula. [ABSTRACT FROM AUTHOR]

Objective: To discuss the mechanisms underlying alkalosis-induced cerebral deficits, we investigate the influences of alkalosis on GABAergic neurons including their intrinsic properties and neuronal encodings in the cortical slices. Methods: Cortical slices were made from FVB-Tg mice in postnatal day 17-22 and were divided into experimental group and control group. Cortical GABAergic neurons for whole-cell recordings were selected under a DIC-fluorescent microscope. Cortical GABAergic neurons were recorded by an Axo Patch-200 B amplifler for analyzing their intrinsic properties. Recording the number of spikes versus the intensities of depolarization pulses was used to evaluate the ability of encoding sequential spikes. Results: 1.Vts values for spikes 1-5 are 24.58±0.68,25.44 ±0.82, 27.02 ±0.78, 27.55 ±0.74 and 28.66 ±0.79 m V under the control, and are 28.32 ±0.78, 30.10 ±0.91, 32.22 ±0.80,32.88±0.76 and 33.54±0.74 m V under high [pH]o. Alkalosis elevates the threshold potentials of producing sequential spikes. Spike ARP appear to be prolonged by high [p H]o, compared with the control group. ARP values are 4.15 ±0.06 and 5.09 ±0.08 ms under the conditions of control and high [pH]o, respectively. Alkalosis prolongs the refractory periods of sequential spikes at cortical GABAergic neurons. 2. The spikes induced by the same intensities of depolarization under the conditions of control and alkalosis are statistically different, indicating that alkalosis impairs the ability of encoding sequential spikes. Conclusions: 1.It is revealed that alkalosis elevates the threshold potential and prolongates the refractory periods of cortical GABAergic neuron.2.Alkalosis appears to reduce the ability of encoding sequential spikes.
