有氧运动配合核心肌群训练对脊髓损伤患者心肺功能及下肢肌力的影响

目的:探究有氧运动配合核心肌群训练对脊髓损伤(Spinal Cord Injury,SCI)患者心肺功能及下肢肌力的影响.方法:回顾性分析我院2018年1月至2020年12月收治的88例不完全脊髓损伤(incomplete spinal cord injury,ISCI)患者临床资料,依据康复训练方式不同,分为研究组和对照组;其中行常规康复措施的41例患者为对照组,基于常规康复措施之上采用有氧运动配合核心肌群训练的47例患者为研究组;行心电监测仪监测、对比两组患者康复训练干预前后静息心率(resting heart rate,RHR)、收缩压(systolic blood pressure,SBP)、舒张压(diastolic blood pressure,DBP)、血氧饱和度(Oxygen saturation,SaO2)、最大摄氧量(maximal oxygen uptake,VO2 Max),行肺功能测定仪监测、对比两组患者康复训练干预前后肺活量(vital capacity,VC)、用力肺活量(forced vital capacity,FVC)、最大通气量MVV(maximum voluntary ventilation)、第1秒用力呼气容积(forced expiratory volume in 1s,FEV1)占预测值百分比,行徒手肌力检查(manual muscle testing,MMT)评估、对比两组患者股四头肌、腘绳肌肌力,行ASIA下肢运动功能评定量表(ASIA-LEMS)评估、对比两组患者下肢运动功能.结果:心功能指标水平比较干预后研究组RHR明显低于对照组,SBP、DBP、SaO2、VO2 Max水平以及干预前后水平差明显高于对照组(P<0.05);肺功能指标水平比较干预后研究组VC％、FVC％、MVV％、FEV1％水平以及干预前后水平差均明显高于对照组(P<0.05);下肢肌力、运动功能比较干预后研究组股四头肌MMT、腘绳肌MMT、ASIA-LEMS评分以及干预前后评分差均明显高于对照组(P<0.05).结论:有氧运动配合核心肌群训练相较于单纯采取常规康复训练法,能够更进一步改善SCI患者心肺功能、增强其下肢肌力从而帮助患者恢复站立、步行能力,最终达到提高患者生存质量的目的.     

儿童胃石症9例诊治经验

目的 总结儿童胃石症的临床特点及治疗经验.方法 回顾性分析郑州大学第一附属医院2009年6月至2020年6月收治的9例胃石症患儿临床资料.结果 9例胃石症患儿均为女性,年龄为4～13岁,其中8例有异食癖,1例发病前曾大量进食柿子.7例经内镜检查确诊,1例经CT确诊,1例经消化道造影确诊.4例经内镜取石治疗,5例经外科手术治疗,最终8例确诊为毛发性胃石症,1例为植物性胃石症.随访1～2 a,9例患儿均恢复良好,胃石症未复发,贫血及营养不良状况均有不同程度改善.结论 儿童胃石症常见于女童,多伴有异食癖,一经诊断应及时治疗,首选内镜取石,内镜取出失败可考虑外科手术治疗,治疗效果及患儿预后好.

基于HPLC指纹图谱、多指标成分含量测定结合化学计量学的怀牛膝质量评价＊

目的 本实验采用HPLC方法建立来自3个产地15批怀牛膝药材的指纹图谱，并对β-蜕皮甾酮，25R-牛膝甾酮，25S-牛膝甾酮进行含量测定，同时通过化学计量学的方法对15批怀牛膝进行质量评价。方法 选用Waters SunFire C₁₈（150 mm×4.6 mm，5 μm）色谱柱，检测波长280 nm，以乙腈-0.1%甲酸水梯度洗脱，流速为1.0 mL·min^-1，柱温25℃，进样量10 μL。以β-蜕皮甾酮峰为参照峰，运用软件《中药色谱指纹图谱相似度评价系统（2012版）》对15批怀牛膝药材进行相似度分析，使用Metabo Analyst 5.0网站进行聚类热图分析，使用SIMCA 14.1软件进行PCA和PLS-DA分析。结果 标定了31个共有指纹峰，指认了3个已知成分，并对其进行含量测定，化学计量学分析结果将15批怀牛膝药材样品分为3类，并且筛选了不同产地间潜在的差异性成分。结论 该方法具有良好的精密度、重复性以及稳定性，可为怀牛膝的质量评价与控制提供科学依据及参考。     

Impact of the COVID-19 pandemic on the hospital attendance of patients with primary cervical cancer in Heilongjiang,China

Information regarding the impact of the coronavirus disease 2019 (COVID-19) pandemic on cervical cancer in mainland China is lacking. We explored its impact on the hospital attendance of patients with primary cervical cancer. We included 1918 patients with primary cervical cancer who initially attended Harbin Medical University Cancer Hospital between January 23, 2019, and January 23, 2021. Attendance decreased by 31%, from 1135 in 2019 to 783 in 2020, mainly from January to June (𝜒² = 73.362, P < .001). The percentage of patients detected by screening decreased from 12.1% in January-June 2019 to 5.8% in January-June 2020 (𝜒² = 7.187, P = .007). Patients with stage I accounted for 28.4% in 2020 significantly lower than 36.6% in 2019 (𝜒² = 14.085, P < .001), and patients with stage III accounted for 27.1% in 2020 significantly higher than 20.5% in 2019 (𝜒² = 11.145, P < .001). Waiting time for treatment was extended from 8 days (median) in January-June and July-December 2019 to 16 days in January-June (𝜒² = 74.674, P < .001) and 12 days in July-December 2020 (𝜒² = 37.916, P < .001). Of the 179 patients who delayed treatment, 164 (91.6%) were for the reasons of the healthcare providers. Compared to 2019, the number of patients in Harbin or non-Harbin in Heilongjiang Province and outside the province decreased, and cross-regional medical treatment has been hindered. The COVID-19 pandemic has negatively impacted cervical cancer patient attendance at the initial phase. These results are solid evidence that a strategy and mechanism for the effective attendance of cervical cancer patients in response to public health emergencies is urgently needed.
