目的探讨伴癫痫发作重症患儿的临床及脑电图特征分析。方法回顾性分析郑州大学第一附属医院儿童重症医学病区2022年1月至2023年12月收治的74例重症患儿的临床资料,运用脑电图监测患儿的癫痫发作情况,并根据有无癫痫发作将患儿分为癫痫发作组和无癫痫发作组。分析患儿的临床特征及癫痫发作的风险因素。结果癫痫发作组患儿的智力发育迟缓、癫痫史、监测前惊厥发作、监测时意识障碍及呼吸衰竭发生率均高于无癫痫发作组,差异有统计学意义(P<0.05)。癫痫发作组患儿脑电图的背景活动异常、发作间期放电、暴发-抑制及低电压和(或)电静息发生率均高于无癫痫发作组患儿,差异有统计学意义(P<0.05)。多因素logistic回归分析显示脑电图监测前惊厥发作、间期放电是重症患儿癫痫发作的独立危险因素(P<0.05)。结论脑电图监测前惊厥发作及间期放电是伴癫痫发作重症患儿的独立危险因素。

With the development of continuous-wave terahertz(THz) sources and array detectors, the pursuit of highfidelity real-time imaging is receiving significant attention within the THz community. Here, we report a real-time full-field THz phase imaging approach based on lensless Fourier-transform THz digital holography.A triangular interferometric layout is proposed based on an oblique illumination of 2.52 THz radiation, which is different from other lensless holographic configurations at other frequencies. A spherical reference beam is generated by a reflective parabolic mirror with minor propagation loss. The complex-valued images are reconstructed using a single inverse Fourier transform of the hologram without complex calculation of the diffraction propagation. The experimental result for a Siemens star validates the lateral resolution of-46 μm in the diagonal direction. Sub-pixel image registration and image stitching algorithms are applied to enlarge the area of the reconstructed images. The dehydration process of an aquatic plant leaf(Hottonia inflata) is monitored for the first time, to the best of our knowledge, at the THz band. Rapid variations in water content and morphology are measured with a time interval of 0.6 s and a total time of 5 min from a series of reconstructed amplitude and phase images, respectively. The proposed method has the potential to become a powerful tool to investigate spontaneous phenomena at the THz band.

The tliree-dimensional copper-doped zeolitic imidazolate framework ZIF-8(Cu^Ⅱ/ZIF-8) was prepared by a metal ion exchange process, using reaction of three different copper salts, zinc nitrate hexahydrate[Zn(NO)3·6H2O] and 2?methylimidazole(2-MelM) under nitrogen atmosphere at the room temperature. The TEM and PXRD results indicated that the morphology of Cu^Ⅱ/ZIF-8 was rhombic dodecahedron and the structure was intact after copper was doped into the porous ZIF-8. The synthesized Cu(NO3)2/ZIF-8 heterogeneous catalyst showed an excellent activity for tlie aerobic oxidation of primary alcohols employing molecular oxygen as oxidant. Moreover, tlie Cu(NO3)2/ZIF-8 heterogeneous catalyst can cycled 15 times without leaching of copper.

Digestive surgical emergencies concern all patients admitted urgently, for whom a decision for surgical intervention may be necessary within 24 hours. They are on guard duty day and night. To carry out this work, we set ourselves the objectives of: 1) Studying digestive surgical emergencies in the general surgery department of the “Mother Child” Le Luxembourg hospital in Bamako, Mali;2) Determine the frequency of digestive surgical emergencies, 3) Describe the clinical and therapeutic aspects, and 4) Analyze the results of treatment. From November 1, 2022 to October 31, 2023, the general surgery department of the “Mother Child” Luxembourg Hospital Center in Bamako, Mali, carried out 139 digestive surgical emergencies whose files were usable;75 men and 64 women, a sex ratio of 1.2. The 20 - 40 years old age group was the most represented, at 40.29%. The average age was 39 years;the extremes 16 years and 93 years with a standard deviation of 21.65 years. The reference concerned 51.08% of our patients. Abdominal pain was the main reason for consultation (100% of cases). In the majority of cases, the physical examination made it possible to make the diagnosis. Faced with certain clinical cases, we requested ultrasound (109/139), ASP (46/139) and CT (15/139). The main etiology was acute appendicitis with 42.45% of cases. The frequency of digestive surgical emergencies was 10.71% of all activities in the general surgery department of the “Mère Enfant” Le Luxembourg hospital center in Bamako. All our patients were seen in consultation by an anesthesiologist before entering the operating room. The surgical consequences were complicated in 11.51% of cases with 7.91% deaths. Surgical site infections accounted for 12.5% of postoperative complications. Eleven deaths were noted, representing 68.75% of complications and 7.91% of our sample. Acute peritonitis was the cause of death in 100% of cases. The average cost of care was 329,000 FCFA.

Introduction: Retroplacental haematoma (RPH) is a very serious complication of pregnancy, with life-threatening consequences for both the mother and foetus. The aim of this study is to determine the incidence and epidemiological characteristics of patients with retroplacental haematoma (RPH) and describe the maternal-foetal complications at Bouaké University Hospital. Methods: This was a cross-sectional prospective, descriptive and analytical study carried out at Bouaké University Hospital over a period of 3 years, from January 1, 2019 to December 31, 2021. All parturients with RPH whose delivery took place at the hospital were included in the study. Data were entered and analysed using EPI INFO software version 7.***.2.6. Results: We recorded 2,0959 deliveries, including 202 cases of RPH, representing an incidence of 0.96%. The 21 to 35 age group accounted for 64.4%, multigestas and large multigestas accounted for 58.5% and multiparas accounted for 41.6%. The main signs on clinical examination were metrorrhagia (100%), arterial hypertension (84.6%) and cervical cerclage (79.7%). Preeclampsia accounted for 50% of per-gestational pathologies. Maternal mortality was 12.9%. Morbidity was dominated by anaemia in 64.1%, followed by disseminated intravascular coagulation (DIC) in 21.8%, and the factors associated with this maternal prognosis were multiple gestations, multiparity, Sher grade IIIb and the occurrence of complications such as DIC, shock, renal complications and HELLP syndrome. Neonatal mortality was 79.2%, and the factors associated with these fetal prognoses were cup size ≥ 5 cm and hematoma weight ≥ 500 g. Conclusion: Better screening of at-risk populations, early diagnosis and treatment in an organised and equipped medical and surgical facility would improve prognosis.

全球不孕不育症中男性因素约占50%,其中无精子症患者通常需要通过手术获取微量精子,或极重度少弱精子症患者的精子数量稀少,采用常规冷冻载体冷冻复苏后难以寻找到存活的精子。因此为避免取卵日无精子可用而取消周期,临床上应用微量精子冷冻载体预先冷冻少量精子,如空卵透明带、海藻酸胶囊、微滴法、麦管法、薄片法、剥卵针等。本文就人类微量精子的不同冷冻载体的研究进行综述,为临床上优化微量精子的冷冻方法提供理论依据。

为提高被噪声、纹理等干扰的图像分割精度,提出了一种基于Bayesian最小误判的活动轮廓模型.首先将目标和背景这两类中心的马氏距离作为误判概率的判决规则,利用方向扩散PDE方程对观测图像进行演化,使得扩散只沿切线方向发生,得到原图像的一个平滑近似图像,从而使目标和背景的马氏距离增大,误判概率减小.然后结合局部二值拟合活动轮廓模型,对特征函数进行迭代演化,直至收敛到目标边缘.最后采用结合梯度下降法和迭代卷积阈值化方法对模型进行数值求解.实验结果表明,提出的模型可以很好地排除干扰信息的影响,准确地提取目标轮廓,误判概率更小.和几个经典变分图像分割模型相比,DSC、IOU等指标值都表明提出模型具有较好的实验效果.

[目的]揭示生态系统服务供需平衡的时空特征,并进一步探究土地利用变化对生态系统服务供需平衡的双重效应及其影响机理。[方法]选取长江中游地区作为研究对象,引入生态系统服务供需量化矩阵分析生态系统供需平衡的时空格局,并运用土地利用变化生态贡献率模型分析土地利用变化对生态系统服务供需平衡的双重影响。[结果](1)研究期间,长江中游地区生态系统服务供需平衡状况持续恶化,主要是由建设用地大规模扩张和耕地、林地大面积缩减带来的生态系统服务供给能力减少和消费需求增加造成的。(2)长江中游地区不同类型生态系统服务供给间的关系在时间尺度上由权衡转为协同,需求和供给平衡间的协同关系在时间尺度上进一步增强,但不同类型生态系统服务供给、需求和供需平衡间的权衡或协同性质及其程度在空间尺度上却存在高度异质。(3)长江中游地区土地利用变化对生态系统服务供需平衡存在改善和恶化双重效应,且恶化效应显著大于改善效应,但引起生态系统服务及其分项服务供需改善和恶化的土地利用变化类型具有时序异质性。[结论]应促进具有协同改善生态系统服务供需平衡的土地利用变化类型,提升与区域主体生态系统服务功能一致的土地利用类型,以及遏制具有协同恶化生态系统服务供需平衡的土地利用变化类型,以实现区域生态系统服务供需改善。
