目的:观察益母草注射液联合缩宫素注射液对剖宫产产妇产后出血的预防效果。方法:选取2020年3月至2023年2月该院收治的182例剖宫产产妇进行前瞻性研究,按照随机数字表法分为研究组与对照组各91例。对照组产后采用缩宫素注射液治疗,研究组在对照组基础上联合益母草注射液治疗,比较两组产后2、24h出血量,住院时间,凝血指标[D-二聚体、活化部分凝血活酶时间(APTT)、凝血酶时间(TT)、凝血酶原时间(PT)和纤维蛋白原]水平,丙二醛水平和不良反应发生率。结果:研究组产后2、24 h出血量低于对照组,住院时间短于对照组,差异均有统计学意义(P0.05)。结论:益母草注射液联合缩宫素注射液预防剖宫产产妇产后出血可降低其产后2、24h出血量以及丙二醛水平,缩短其住院时间,改善其凝血指标水平,效果优于单纯缩宫素注射液预防。

INTRODUCTION Japan’s first successful lunar landing mission,Smart Lander for Investigating Moon(SLIM),was landed on the Moon on January 19th,*** made a precise landing within 100 m of the targeted landing zone(central coordinates 13.316°S,25.251°E),which is located around the Shioli crater(D=270 m,central coordinates as 13.33°S,25.23°E)in the southwestern ejecta of the Theophilus crater(D=98.6 km,central coordinates as 11.45°S,26.28°E).

To study the effects of early signal substances induced by heat stress in brains of Kunming mice,six-month-old mice(n 572)were pretreated with heat stress and subsequent ischemia/reperfusion by clipping of their bilateral cervical common arteries for 7 *** to different treatments,animals were randomly divided into four groups:(1)normal control group;(2)heat stress pre-treatment followed by ischemia and reperfusion group(HS/IR);(3)ischemia and reperfusion group(IR);(4)heat stress group(HS).Animals in the later three groups were subdivided into 3 subgroups(1 day,4 days,14 days),*** changes in the expression of cAMP res-ponse element binding protein(CREB)and calcitonin gene-related peptide(CGRP)were detected by immuno-histochemistry and computer image analysis *** results showed that compared with the normal group,the expressions of CREB in the hippocampal CA1 region increased significantly in the HS,HS/IR and IR groups(P,0.05).Compared to the normal group,heat stress could result in CGRP excretion and redistribution in the cerebrum,with the highest level in the 4 d HS/IR *** heat stress,CGRP immunoreactivity was observed in varicose fibers and neuronal perikarya within the CA1 *** results indicate that heat stress can induce CREB expression,which in turn stimulates CGRP secretion.

In this paper, the continuous-time independent edge-Markovian random graph process model is constructed. The authors also define the interval isolated nodes of the random graph process, study the distribution sequence of the number of isolated nodes and the probability of having no isolated nodes when the initial distribution of the random graph process is stationary distribution, derive the lower limit of the probability in which two arbitrary nodes are connected and the random graph is also connected, and prove that the random graph is almost everywhere connected when the number of nodes is sufficiently large.

The effects of heat stress on the neurons in hippocampal CA1 region of brain ischemia/reperfusion were *** mice were pretreated with heat stress fol-lowed by ischemia/reperfusion by clipping bilateral cervical common arteries for 7 *** were divided randomly into four groups as follows:(1)normal control group;(2)heat stress pretreated subsequent to ischemia/reperfusion group(HS/IR);(3)ischemia/reperfusion group(IR);and(4)heat stress group(HS).Animals in the last three groups were subdivided into three subgroups:1 d,4 d,14 d *** Morris water maze was used to test the ability of learning and memorizing,Nissl staining was used to count the average number of survived neurons in hippocampal CA1 region,and immunohistochemistry combined with image analysis system to detect the changes of Microtubule associated protein 2(MAP-2)*** results showed that mice in IR group exhibited increased escape latency when compared with that of normal,HS and HS/IR groups(P<0.01),and the mice in IR group adopted an inefficient search strategy,major in circling and restricted searching *** staining results showed a significant reduction in the number of pyra-midal neurons in hippocampal CA1 regions in HS/IR and IR groups,with a decrease in IR group(P<0.01).Compared with normal group,the expression of MAP-2 in hippocampal CA1 region obviously decreased in IR group(P<0.05).The present results indicate that heat stress pretreatment can improve the spatial learning and memorizing function through protection to hippocampal neurons.

Research on ad-hoc network connectivity has mainly focused on asymptotic results in the number of nodes in the network. For a one-dimensional ad-hoc network G1, assuming all the nodes are independently uniform distributed in a closed interval [0, Z]（z ∈ R^＋）, we derive a generic formula for the probability that the network is connected. The finite connected ad-hoc networks is analyzed. And we separately suggest necessary conditions to make the ad-hoc network to be connected in one and two dimensional cases, facing possible failed nodes （f-nodes）. Based on the necessary condition and unit-disk assumption for the node transmission, we prove that the nodes of the connected two-dimensional ad-hoc networks （G2） can be divided into at most five different groups. For an f-node no in either of the five groups, we derive a close formula for the probability that there is at least one route between a pair of nodes in G2 -- {no}.

A branching model {Z n} n≥0is considered where the offspring distribution of the population’s evolution is not only dependent on the population size, but also controlled by a Markovian environmental process {ξ n} n≥0. For this model, asymptotic behaviour is studied such as limn→∞Z n and limn→∞Z n/m n in the case that the mean m k, θof the offspring distribution converges to m>1 as the population size k grows to ∞. In the case that {ξ n} n≥0is an irreducible positive recurrent Markov chain, certain extinction (i.e. P(Z n=0 for some n)=1) and noncertain extinction (i.e. P(Z n=0 for some n)<1) are studied.

Now we extend one method into a sequence of binomial data, propose a stepwise confidence interval method for toxic-ity study, and also in our paper, two methods of constructing intervals for the risk difference are proposed. The first one is based on the well-known conditional confidence intervals for odds ratio, and the other one comes from Santner“small-sample confidence intervals for the difference of two success probabilities”, and it produces exact intervals, through employing our method.
