目的 探讨基于肺康复的阻抗训练联合营养支持对老年慢性阻塞性肺疾病（COPD）衰弱患者肌少症及运动耐量的影响。方法 将2024年1月—2025年5月收治的80例老年COPD衰弱合并肌少症患者，分为对照组、观察组，各40例。所有患者均采取常规药物治疗，对照组予以营养支持，观察组在对照组基础上增加基于肺康复的阻抗训练。比较两组治疗前、治疗3个月后肌少症改善情况，运动耐量，肺功能指标，衰弱状态及生活质量。结果 治疗3个月后，观察组骨骼肌指数、握力、股四头肌肌厚度均较治疗前提高，且与对照组相比，观察组更高（P＜0.05）；治疗3个月后，两组6 min步行距离、日常活动代谢当量均较治疗前提高，Borg量表评分降低，且与对照组相比，观察组改善幅度更大（P＜0.05）；治疗3个月后，两组第一秒用力呼气容积（FEV1）、FEV1/用力肺活量（FVC）、最大通气量（MVV）均较治疗前改善，且与对照组相比，观察组更优（P＜0.05）；治疗3个月后，两组Fried衰弱表型评分、COPD评估测试（CAT）总分、圣乔治呼吸问卷（SGRQ）总分均较治疗前降低，且与对照组相比，观察组更低（P＜0.05）。结论 老年COPD衰弱合并肌少症患者采取基于肺康复的阻抗训练联合营养支持可改善其肌少症情况，提升运动耐量，并且提升患者肺功能水平，改善衰弱状态，提升生活质量。

       Objective To explore the effects of impedance training based on pulmonary rehabilitation combined with nutritional support on sarcopenia and exercise tolerance in elderly patients with chronic obstructive pulmonary disease（COPD）and frailty．Methods Eighty elderly patients with COPD and frailty complicated by sarcopenia，admitted from January 2024 to May 2025，were selected as the study subjects and divided into a control group and an observation group，with 40 patients in each group．All patients received conventional drug therapy．The control group received nutritional support，while the observation group received additional impedance training based on pulmonary rehabilitation on top of the matched group’s treatment．The improvement of sarcopenia，exercise tolerance，pulmonary function index，weakness status and quality of life before and 3 months after treatment were compared between the two groups．Results After 3 months of treatment，the skeletal muscle index，grip strength and quadriceps thickness of the observation group increased compared with that before treatment，and compared with the control group，the observation group was higher（P＜0.05）．After 3 months of treatment，the 6 min walking distance and daily activity metabolic equivalent of both groups increased compared with that before treatment，and the Borg Scale score decreased．Compared with the control group，the improvement of the observation group was better（P＜0.05）．After 3 months of treatment，Forced Expiratory Volume in one second（FEV1），FEV1/Forced Vital Capacity（FVC）and Maximal Voluntary Ventilation（MVV）of both groups improved compared with that before treatment，and the observation group  was better than that of the control group（P＜0.05）．After 3 months of treatment，the Fried weakness phenotype score，COPD Assessment Test（CAT）total score and St. George’s Respiratory Questionnaire（SGRQ）total score of both groups were lower than that before treatment，and the observation group  was lower than that of the control group（P＜0.05）．Conclusions Impedance training based on pulmonary rehabilitation combined with nutritional support can improve sarcopenia，enhance exercise tolerance，and improve pulmonary function levels，frailty status，and quality of life in elderly patients with COPD and frailty complicated by sarcopenia．

       目的 探究1990—2023年中国人群下背痛（LBP）疾病负担，并预测2024—2040年LBP疾病负担发展趋势，为公共卫生政策制定提供数据支撑。方法 基于GBD2023数据库，采用Joinpoint模型、分解分析（decomposition analysis）量化我国LBP负担变化趋势，最后通过ARIMA（autoregressive integrated moving average model）模型预测未来趋势。结果 2023年我国LBP患病人数达9 532.40万人，发病人数为4 138.36万人，伤残调整生命年（DALYs），虽然患病人数、发病人数及DALYs绝对数较1990年显著增长，但年龄标准化率（ASR）均呈显著下降趋势（AAPC依次为-0.90%、-0.84%、-0.89%）。分解分析表明，人口年龄结构是我国LBP疾病负担增长的主要正向驱动因素，流行病学趋势变化对患病率和DALYs起关键抑制作用，且存在明显性别差异。ARIMA模型预测显示，2024—2040年男性和女性LBP相关ASR将持续下降，但我国女性LBP负担仍高于男性。结论 我国LBP负担沉重，受人口结构、性别差异、行为与职业等多方面因素影响，未来需通过分人群、分职业精准干预及多部门协同，持续降低疾病负担。

     Objective To explore the characteristics of disease burden of low back pain（LBP） in the Chinese population from 1990 to 2023，and predict its development trend from 2024 to 2040，so as to provide data support for the formulation of public health policies．Methods Based on the Global Burden of Disease Study 2023（GBD 2023） database，the Joinpoint model and decomposition analysis were adopted to quantify the changing trend of LBP burden in China．The autoregressive integrated moving average（ARIMA） model was used to predict the future trend，with the data for prediction stratified by gender and age group．Results In 2023，the number of LBP patients in China reached 95.3240 million，the number of incident cases was 41.3836 million，and the disability-adjusted life years（DALYs） were 10.6359 million person-years．Although the absolute numbers of prevalent cases，incident cases，and DALYs increased significantly compared with 1990，the age-standardized rates（ASRs） all showed a significant downward trend（average annual percentage changes were -0.90%，-0.84%，and -0.89%，respectively）．Decomposition analysis revealed that population age structure was the primary positive driving factor for the growth of LBP disease burden in China，while changes in epidemiological trends played a key inhibitory role in prevalence and DALYs，with significant gender differences．ARIMA model prediction indicated that the LBP-related ASRs would continue to decrease in both males and females from 2024 to 2040，but the LBP burden in females would remain higher than that in males in China．Conclusions The baseline burden of LBP in China is heavy，affected by multiple factors such as population structure，gender differences，behavioral and occupational factors．In the future，targeted interventions for specific populations and occupations，as well as multi-sectoral collaboration，are needed to continuously reduce the disease burden．

       目的 探究体成分变化对肥胖患者肾小球高滤过的影响。方法 根据纳入排除标准，连续收集在中南大学湘雅二医院营养科及代谢内分泌科就诊的肥胖患者（体质指数≥28 kg/m²），对其随访3个月以上，纳入体质量减轻≥5%的患者，记录一般人口学、人体测量学、体脂率（BFP）、体脂肪量（BFM）、内脏脂肪面积（VFA）和骨骼肌量（SMM）等体成分和实验室检验数据，计算估计肾小球滤过率（eGFR）。肾小球高滤过被定义为eGFR大于普通人群第95个百分位数，根据此标准分为肾小球高滤过组和正常滤过组，比较组间一般人口学资料、生化指标及体成分的差异，绘制限制性立方样条图分析体成分的变化与eGFR变化之间的非线性关联。结果 （1）共收集85例肥胖患者初复诊资料，其中肾小球正常滤过患者43例，肾小球高滤过患者42例，男性35例，女性50例；（2）单因素分析提示肾小球高滤过患者减重前后eGFR差异有统计学意义［143.34 mL/（min·1.73 m²） vs 125.68 mL/（min·1.73 m²）；（3）非线性相关分析结果显示肥胖肾小球高滤过患者eGFR的变化与VFA的变化相关（P=0.015 1），与BFP的变化相关（P=0.022 6）。结论 肥胖患者减重后，随着VFA和BFP的下降可能改善肾小球高滤过。

    Objective This study aimed to investigate the impact of alterations in body composition on glomerular hyperfiltration in obese patients．Methods According to predefined inclusion and exclusion criteria，obese patients（body mass index ≥28 kg/m2）from the department of clinical nutrition and the department of metabolism and endocrinology at Second Xiangya Hospital of Central South University were consecutively enrolled．Patients who achieved a weight loss of ≥5% after more than three months of follow-up were included．Data on general demographics，anthropometric measurements，body composition parameters-including body fat percent（BFP），body fat mass（BFM），visceral fat area（VFA），and skeletal muscle mass（SMM）-and laboratory test results were collected．The estimated glomerular filtration rate（eGFR）was calculated．Glomerular hyperfiltration was defined as an eGFR greater than the 95th percentile for the general population．Based on this criterion，patients were categorized into a hyperfiltration group and a normofiltration group．Differences in demographic characteristics，biochemical indices，and body composition parameters between the two groups were compared．Restricted cubic spline curves were plotted to analyze the non-linear relationship between changes in body composition and changes in eGFR．Results （1）A total of 85 obese patients（35 males and 50 females） with initial and follow-up data were included，comprising 43 patients with normofiltration and 42 with hyperfiltration；（2）Univariate analysis indicated a statistically significant difference in eGFR before and after weight loss in the hyperfiltration group（143.34 mL/min/1.73m² vs 125.68 mL/min/1.73m²，P＜0.001）；（3）Non-linear correlation analysis revealed that changes in eGFR among obese patients with hyperfiltration were significantly associated with changes in VFA（P=0.015 1）and changes in BFP（P=0.022 6）．Conclusions Weight loss in obese patients may ameliorate glomerular hyperfiltration，potentially mediated through reductions in VFA and BFP．

      目的  探讨精子DNA碎片指数（DFI）对体外受精-胚胎移植（IVF-ET）胚胎发育及妊娠结局的影响，为优化男性生育力评估及辅助生殖治疗策略提供依据。方法  回顾性分析2023年1月—2024年1月于徐州市妇幼保健院接受IVF-ET治疗的126对不孕夫妇，根据男方DFI检测结果分为低碎片组（DFI≤15%，n=42）、临界组（15%＜DFI＜30%，n=45）和高碎片组（DFI≥30%，n=39）。比较三组患者受精相关指标、胚胎发育指标及妊娠结局指标的差异，并分析DFI与各指标的相关性。结果  低碎片组双原核率（2PN）率、优质胚胎率及囊胚形成率均高于临界组和高碎片组（P＜0.001），低碎片组1PN率、多PN率均低于临界组和高碎片组（P＜0.001）；三组种植率、临床妊娠率、早期流产率比较差异无统计学意义（P＞0.05），但高碎片组活产率低于低碎片组（P＜0.05）。相关性分析结果表明，DFI与优质胚胎率（r=-0.412，P＜0.001）、囊胚形成率（r=-0.387，P＜0.001）、活产率（r=-0.287，P=0.012）呈负相关，与早期流产率（r=0.206，P=0.059）、种植率（r=-0.215，P=0.058）、临床妊娠率（r=-0.203，P=0.072）无显著相关性。结论  精子DNA碎片指数是影响IVF-ET胚胎发育及妊娠结局的重要因素，高DFI主要通过降低胚胎发育潜能及增加流产风险导致活产率下降，临床需对高DFI患者进行干预以改善治疗结局。

       目的  本研究旨在探讨不同俯卧位通气（PPV）时间对重症肺炎合并胃肠功能障碍患者肠内营养耐受性的影响。方法  选择2020年7月—2023年7月在天津市人民医院重症监护病房（MICU）治疗的80例重症肺炎合并胃肠功能障碍患者为研究对象, 按每日PPV时间分为长时组（≥12 h, n=40）和短时组（<12 h, n=40）。比较两组患者一般资料、氧合指数、胃肠功能指标[腹内压、血清促胃液素（GAS）和血管活性肠肽（VIP）]、肠内营养达标率、胃肠并发症率等。结果  短时组治疗后, 1 d、3 d、5 d氧合指数为（189.93±33.72）、（247.53±63.01）、（325.03±58.11）mmHg,高于长时组的（161.63±36.88）、（191.83±57.65）、（267.95±46.25）mmHg,均P<0.05; 胃残留量为（29.00±7.92）、（19.75±4.45）、（11.00±1.87） mL低于长时组的（75.03±23.29）、（53.13±11.99）、（21.70±5.52） mL, 均P<0.05。短时组治疗后腹内压[（8.53±2.05）mmHg vs （9.75±2.05） mmHg]、VIP水平[（61.14±7.63） vs （67.49±4.43） pg/mL]低于长时组,GAS水平[（65.02±8.84） vs （54.22±9.21）pg/mL]升高（均P<0.05）。短时组总胃肠并发症发生率（7.50%）低于长时组（25.00%）, P=0.034。结论  对于重症肺炎合并胃肠功能障碍患者,每日PPV时间≤12 h可改善氧合并降低胃肠并发症风险, 可能与减轻腹压、调节胃肠激素分泌及提升肠内营养耐受性相关。

      Objective To explore the effect of different duration of prone position ventilation（PPV）on enteral nutritional tolerance in patients with severe pneumonia combined with gastrointestinal dysfunction．Methods A total of 80 patients with severe pneumonia complicated by gastrointestinal dysfunction were treated in the Medical Intensive Care Unit（MICU）of a hospital from July 2020 to July 2023, and were selected as the research subjects．They were divided into the long-duration group（≥12 hours, n=40）and the short-duration group（<12 hours, n=40）according to the daily duration of PPV．The general data, oxygenation index, gastrointestinal function indicators（intra-abdominal pressure, serum gastrin[GAS] and vasoactive intestinal peptide[VIP]）, enteral nutrition achievement rate, and gastrointestinal complications of the two groups were compared．Results The oxygenation index of the short-duration group at 1 d, 3 d,a nd 5 d after treatment（[189.93±33.72], [247.53±63.01], and[325.03±58.11] mmHg, respectively）was significantly higher than that of the long-duration group（[161.63±36.88], [191.83±57.65], and[267.95±46.25] mmHg,respectively, all P<0.05）．The gastric residual volume of the short-duration group（[29.00±7.92], [19.75±4.45], and[11.00±1.87] mL, respectively）was significantly lower than that of the long-duration group（[75.03±23.29], [53.13±11.99], and[21.70±5.52] mL, respectively, all P<0.05）．The intra-abdominal pressure（[8.53±2.05] vs [9.75±2.05] mmHg）and VIP level（[61.14±7.63] vs [67.49±4.43] pg/mL）of the short-duration group after treatment were significantly lower than those of the long-duration group, while the GAS level（[65.02±8.84] vs [54.22±9.21] pg/mL）was significantly higher（all P<0.05）．The total incidence of gastrointestinal complications in the short-duration group（7.50%）was significantly lower than that in the long-duration group（25.00%, P=0.034）．Conclusions For patients with severe pneumonia complicated by gastrointestinal dysfunction, a daily duration of PPV within 12 hours can improve oxygenation and reduce the risk of gastrointestinal complications, which may be related to the reduction of intra-abdominal pressure, regulation of gastrointestinal hormone secretion, and improvement of enteral nutrition tolerance． 

肥胖是一种以慢性低度炎症为特征的进展性疾病,与多种代谢性疾病的发生、发展密切相关。脂肪组织作为一种内分泌和免疫器官,可分泌多种生物活性物质及炎症因子,参与肥胖患者体内的代谢过程。减重手术是治疗病态性肥胖及相关代谢性疾病的有效方法之一,能够调节机体内的炎症反应、有效改善代谢状态。但减重手术对于炎症因子的作用如何,目前国内外的文献证据仍有争议。本文将系统阐述肥胖与代谢性炎症的关系以及减重手术对炎症因子的影响,旨在为肥胖代谢外科的诊疗过程提供参考。

Obesity is a progressive disease characterized by chronic low-grade inflammation,which is closely related to the occurrence and development of a variety of metabolic diseases．As an endocrine and immune organ,adipose tissue can secrete a variety of bioactive substances and inflammatory factors,which participate in the metabolic process of obese patients．Bariatric surgery is one of the effective methods for the treatment of morbid obesity and related metabolic diseases,which can regulate the inflammatory response in the machine and effectively improve the metabolic state．However,the effect of bariatric surgery on inflammatory factors is still controversial at home and abroad．This article will systematically explain the relationship between obesity and metabolic inflammation and the effect of bariatric surgery on inflammatory factors,aiming to provide a reference for the diagnosis and treatment process of bariatric surgery．

目的 分析阿莫西林克拉维酸钾与第三代头孢类抗菌药联合应用于新生儿肺炎患儿的应用效果及其对患儿肠道菌群的影响。方法 选择在2021年2月—2022年11月期间于我院新生儿科接受相关治疗的100例新生儿肺炎患儿,依照简单随机化法将患儿分为研究组（n=50）及参照组（n=50）。给予参照组常规新生儿肺炎治疗,在此基础上给予研究组患者阿莫西林克拉维酸钾与第三代头孢类抗菌药的联合治疗。治疗结束后对比两组患儿的血清因子水平、肠道菌落情况、临床疗效以及不良反应发生情况。结果 治疗前,两组患儿的血清因子水平、肠道内菌群数量比较差异无统计学意义（P>0.05）,治疗后两组患儿的降钙素原（procalcitonin,PCT）、C-反应蛋白（C-reactive protein,CRP）、白细胞计数（white blood cell count,WBC）、肠球菌、肠杆菌、双歧杆菌以及乳酸杆菌水平均有改善（P<0.05）,其中研究组的PCT、CRP、WBC、肠球菌、双歧杆菌以及乳酸杆菌数量低于参照组,而研究组的肠杆菌数量高于参照组;同时研究组的临床有效率（94.00%）与参照组的临床有效率（86.00%）比较差异无统计学意义（P>0.05）;两组患儿的不良反应发生率比较差异无统计学意义（P>0.05）,但其中研究组腹泻的发生率高于参照组（P<0.05）。结论 在对新生儿肺炎患儿进行治疗时采取阿莫西林克拉维酸钾单纯治疗与阿莫西林克拉维酸钾+第三代头孢类抗菌药（头孢他啶）的临床疗效相当,联合用药虽能更为显著地减少患儿机体的细菌数量,改善血清因子水平,但更易发生腹泻的并发症,且为了减少耐药性,应适当采用单独用药。

Objective To analyze the application effect of amoxicillin clavulanate potassium combined with third-generation cephalosporin antibiotics in children with neonatal pneumonia and its impact on the intestinal microbiota．Methods From February 2021 to November 2022,100 newborns with pneumonia who received relevant treatment in the Department of Neonatology at the First People’s Hospital of Shangqiu City were randomly divided into a study group（n=50）and a reference group（n=50）using a simple randomization method．Routine treatment was provided for neonatal pneumonia in the reference group,and on this basis,a combination treatment of amoxicillin,clavulanate potassium,and third-generation cephalosporin antibiotics was applied on the study group patients．After treatment,the serum factor levels,intestinal colony status,clinical efficacy,and incidence of adverse reactions were compared between the two groups of children．Results Before treatment,there were no statistically significant differences in serum factor levels and intestinal microbiota between the two groups of children（P>0.05）．After treatment,the levels of procalcitonin（PCT）,C-reactive protein（CRP）,white blood cell count（WBC）,Enterococcus,Enterobacter,Bifidobacterium,and Lactobacillus in the two groups of children improved（P<0.05）,with the levels of PCT,CRP,WBC,the number of Enterococcus,Bifidobacterium,and Lactobacillus in the study group was lower than that in the reference group,while the number of Enterobacter in the study group was higher．There was no statistically significant difference（P>0.05）in the clinical response rate between the study group（94.00%）and the reference group（86.00%）．There was no statistically significant difference in the incidence of adverse reactions between the two groups of children（P>0.05）,but the incidence of diarrhea in the study group was higher than that in the reference group（P<0.05）．Conclusions The clinical efficacy of amoxicillin clavulanate potassium alone and amoxicillin clavulanate potassium+third-generation cephalosporin antibiotics（ceftazidime）in the treatment of newborns with pneumonia is comparable．Although the combination therapy can significantly reduce the number of bacteria in the body of children and improve serum factor levels,it is more prone to complications of diarrhea．In order to reduce drug resistance,separate medication should be appropriately used．

Objective To explore the impact of systematic nursing process intervention on the emergency response and prognosis of patients with cerebral hemorrhage．Methods By retrospective analysis,210 patients with cerebral hemorrhage admitted to the emergency department of the Third Affiliated Hospital of Xinxiang Medical College from February 2022 to February 2023,105 patients with routine nursing intervention from February 2022 to August 2022 were selected as the routine group,and 105 patients with systematic nursing process intervention from September 2022 to February 2023 were selected as the study group．The rescue efficiency,first aid effect,complication rate,prognosis levels and nursing satisfaction of the two groups were compared．Results The total rescue time,consultation to diagnosis,triage to consultation,reception to triage and the response time to visit in the study group were significantly lower（P<0.05）．The total emergency response rate of the study group was higher than that of the conventional group,and the incidence of complications was significantly lower（P<0.05）．One month and 3 months after discharge,NIHSS score decreased in both groups,MMSE score increased,and the change range was greater in the study group（P<0.05）．The nursing satisfaction of the study group was significantly higher（P<0.05）．Conclusions For patients with cerebral hemorrhage,systematic nursing process intervention in the first aid process can improve the rescue efficiency and first aid effect of patients,reduce the incidence of complications,improve the neurological function defect of patients,improve the prognosis level,and the patient satisfaction is higher．

目的 探索干预因素对4~12岁孤独症谱系障碍（ASD）患儿社交反应的影响,为开展ASD患儿的早期干预提供参考。方法 选取于2020年1月—2023年3月在清远市妇幼保健院儿童神经与发育中心康复干预的ASD患儿,采用社交反应量表（SRS）对患儿进行社交行为评估,采用自编一般情况问卷对家长进行问卷调查,调查内容包括患儿的基本情况（性别、共患病情况、干预时长、上学情况等）。结果 202例ASD患儿中,男性患儿162例（80.2%）,女性40例（19.8%）,性别对社交反应的影响比较差异无统计学意义（t=2.969,P>0.05）。共患病方面,无共患病的ASD患儿与共患智力发育障碍及注意缺陷多动障碍的患儿相比,其SRS得分差异有统计学意义（F=6.920,P<0.05）。在上学情况方面,普通学校就读的患儿与特殊学校及未上学的患儿相比,其SRS得分差异有统计学意义（F=3.823,P<0.05）,但在特殊学校就读的患儿与未上学的患儿相比,差异无统计学意义（P>0.05）。在干预时长方面,干预≥1年与干预<1年及未干预的患儿比较,其SRS得分更低,差异有统计学意义（F=4.477,P<0.05）,但干预<1年与未干预患儿相比,两者差异无统计学意义（P>0.05）。结论 ASD患儿中,是否患有其他无共患病、上学情况、干预时长会影响其社交反应;存在共患疾病的ASD患儿社交反应表现更差;相较于就读特殊教育机构和未上学的患儿,就读于普通学校的ASD患儿社交障碍程度更轻;干预时间越长,其社交障碍程度也越轻。

Objective To explore the impact of intervention factors on social response in children with autism spectrum disorder（ASD）aged 4—12,and to provide reference for early intervention in children with ASD. Methods Children with ASD who underwent rehabilitation intervention at the Children's Neurology and Development Center of Qingyuan Maternal and Child Health Hospital from January 2020 to March 2023 were selected．The social behavior of the children was evaluated using the Social Response Scale（SRS）,and the parents were surveyed using a self-made general situation questionnaire．The survey content included the basic information of the children（gender,comorbidity,intervention duration,and school attendance,etc．）. Results Among the 202 cases of ASD,162 were male（80.2%）and 40 were female（19.8%）．There was no statistically significant difference in the impact of gender on social response（t=2.969,P>0.05）．In terms of comorbidities,there was a statistically significant difference in SRS scores between ASD children without comorbidities and those with comorbidities such as intellectual development disorder and attention deficit hyperactivity disorder（F=6.920,P<0.05）．In terms of school attendance,there was a statistically significant difference in SRS scores between children enrolled in regular schools and those who attended special schools and those who did not attend school（F=3.823,P<0.05）,but there was no statistically significant difference between children enrolled in special schools and those who did not attend school（P>0.05）．In terms of intervention duration,compared with children with intervention≥1 year and those with intervention<1 year and no intervention,the SRS score was lower and the difference was statistically significant（F=4.477,P<0.05）．However,compared with children with intervention<1 year and those without intervention,the difference was not statistically significant（P>0.05）. Conclusions No comorbidities,attending regular schools,and intervention duration≥1 year are positive factors that affect social response．Children with ASD who have comorbidities have poorer social response performance;compared to children who attend special education institutions and those who do not attend school,children with ASD who attend regular schools have lower levels of social impairment;the longer the intervention time,the lighter the degree of social impairment．
