作者：刘昭睿郭厚静徐日娥内蒙古电力科学研究院内蒙古呼和浩特010020

基于内蒙古电网黑启动方案(即通过万家寨水电站启动准大电厂),提出500 kV主网恢复送电的2种方案:一是先给重要负荷送电、后启电厂;二是先启电厂、后给重要负荷送电,并对2种方案下的工频过电压和操作过电压进行仿真计算分析。得出结论:方... 详细信息

基于内蒙古电网黑启动方案(即通过万家寨水电站启动准大电厂),提出500 kV主网恢复送电的2种方案:一是先给重要负荷送电、后启电厂;二是先启电厂、后给重要负荷送电,并对2种方案下的工频过电压和操作过电压进行仿真计算分析。得出结论:方案1需在宁格尔侧加装无功补偿装置;方案2可直接利用现有的电网进行黑启动,较方案1更安全,为内蒙古500 kV电网黑启动的最佳方案。

随着不同电压等级专线用户大量接入电网,各电压等级的无损电量占比逐步增大,含无损电量的统计线损率减小,针对无损电量占比掩盖了有损电量部分的真实线损情况这一问题,分析了无损电量占比与扣除无损电量前、后线损率的关系,并得出结论:... 详细信息

随着不同电压等级专线用户大量接入电网,各电压等级的无损电量占比逐步增大,含无损电量的统计线损率减小,针对无损电量占比掩盖了有损电量部分的真实线损情况这一问题,分析了无损电量占比与扣除无损电量前、后线损率的关系,并得出结论:无损电量占比增大,含无损电量的线损率成比例减小。据此可对线损率进行估算、对各地区的实际线损情况进行横向对比,有效提高线损管理水平。

Background: Breast cancer mortality remains high in the majority of developing countries. The Ministry of Health has established two population-based cancer registries in Benin: the first one in Cotonou in 2014 and the second one in Parakou in 2017. However, there is a scarcity of data on breast cancer survival and prognosis in Benin Republic. Objective: This study sought to investigate epidemiological, diagnostic, and survival aspects of breast cancer in Parakou, based on data from its population-based cancer registry from 2017 to 2021. Method: For descriptive and analytical purposes, we used a retrospective cohort design. From January 24, 2022 to August 31, 2022, data were collected in all health facilities covered by the Parakou population-based cancer registry using an individual questionnaire. Survival and prognosis analysis were performed using KAPLAN MEIER method and David COX proportional hazard model respectively. Result: A total of 81 patients have been included in this study. The incidence rate of breast cancer in Parakou was 17.5 per 100,000 person-years with a mortality rate of 2.76 per 100,000 person-years. The median age at diagnosis was 44.50 years with extremes ranging from 19 to 76 years and a predominance of 40 - 50 years age group. The median survival time was estimated at 30 months with an overall 5-year survival of 47%. Young age at diagnosis (p-value = 0.002) and advanced stage at diagnosis (p-value = 0.000) had a negative impact on survival in women. The combination of surgery and chemotherapy improved survival (p-value = 0.018). Conclusion: Breast cancer is still a public health issue in Parakou. It comes out mandatory that resources be made available to make screening, early diagnosis and appropriate treatment of breast cancer affordable.

牛猝死症(sudden death syndrome,SDS)又称为暴死症或急性死亡综合征,近年来许多病畜前期不见任何症状就突然死亡。该病一般病程也不超过12 h,各年龄段的牛均能发病,是一种发病急、死亡率高的疾病。发病牛以全身实质性器官衰竭以及消化道出血、小肠坏死为主要病变特征。目前发现该病的致病因素较多并且给中国的养牛业造成了巨大经济损失。本综述就近年来牛猝死症的发病原因、临床症状、病理变化以及防治措施等研究进展作总结概述,以期对该病的深入研究提供科学的参考。

Vegan diet in lactating women can induce vitamin B12 deficiency for their children with risk of an impaired neurological development. A 9.5-month-old girl presented with impaired growth and severe hypotonia. She had a macrocytic anemia secondary to vitamin B12 deficiency. MRI showed cerebral atrophy. She was exclusively breastfed. Her mother was also vitamin B12 deficient, secondary to a vegan diet. She had a macrocytic anemia when discharged from the maternity. Vegan diet is a totally inadequate regimen for pregnant and lactating women, especially for their children. Prevention is based on screening, information and vitamin supplementation.

目的探讨胃癌根治术后胃瘫综合征(PGS)的危险因素。方法收集260例胃癌根治术患者,根据术后是否发生PGS分为试验组(21例)和对照组(239例),比较两组患者的临床资料,并将具有统计学差异的因素进行多因素Logistic回归分析。结果两组患者在年龄、合并基础疾病、术前幽门梗阻、精神因素、胃肠吻合方式、手术时间、术中出血量、术后每日补液量和术后肠内营养开始时间等方面比较,差异有统计学意义(P<0.05)。Logistic回归分析结果显示,术前幽门梗阻、合并基础疾病、手术时间长、B-Ⅱ式吻合和不良心理因素等为胃癌根治术后PGS发生的独立危险因素(P<0.05)。结论胃癌根治术后发生PGS的相关因素较多,对于术前幽门梗阻、合并基础疾病、手术时间较长、术中采用B-Ⅱ式吻合和不良心理因素的患者应给予高度重视,及时采取相应干预措施,以降低PGS的发生率。

The new coronavirus (SARS-CoV-2) broke out in Wuhan in China in December 2019, causing severe pneumonia and deaths, soon in March 2020, it reached pandemic level, affecting several countries including Brazil. The disease was named COVID-19, with characteristics of most infected having mild and moderate symptoms and a part severe symptom. The disease has already reached 158 ethnic groups, which have high vulnerability and limited access to health services. The objective is to investigate the clinical and spatial characteristics of Severe Acute Respiratory Syndrome of COVID-19 in the indigenous peoples of Brazil. It is an epidemiological, cross-sectional, analytical ecological study, based on data from the OpenDataSUS platform from 01/01/2020 to 31/08/2020. Profile variables, signs and symptoms and risk factors/comorbidities. The data were analyzed by Bioestat 5.3. There were 1,207 cases and 470 deaths. Profile: male gender (59.48%) means age 53 years. Signs and symptoms: fever (74.23%), cough (77.71%), sore throat (35.62%), dyspnea (69.34%), respiratory discomfort (62.80%), O2 saturation 2 saturation < 95% (69.36%). Risk factors and comorbidities (45.89%) were associated with deaths (54.04%). About comorbidities, chronic cardiovascular diseases represented (18.97%) and Diabetes Mellitus (18.97%), and associated with deaths: Chronic Cardiovascular Disease (24.46%). Being admitted to the ICU has a risk of death in (OR-3.96- < 0.0001-CI-2913/5383) followed by not being vaccinated against influenza (OR-1.85- < 0.0001-CI-1358/2528). The public and health policies of Brazil should be directed to control the dissemination of COVID-19 in this population, that COVID-19 evolves in the same intensity, however, the indigenous have vulnerabilities that can increase the impact of the pandemic in this population.
