目的 探讨放血疗法对小儿发热的疗效。方法 检索包括中国生物医学文献数据库（CBM）、CNKI、万方、维普、PubMed、Embase、Web of Science、Cochrane Library等8个中、英文数据库自建库至2025年5月所发表的放血疗法治疗小儿发热的随机对照试验研究（RCT），2名研究人员根据Cochrane系统评价手册（5.1.0版）推荐的偏倚风险评估表对所纳入文献进行质量评估，采用RevMan 5.4软件对纳入文献质量进行系统分析。结果 纳入19项RCT，共2 224例患儿，其中观察组1 118例、对照组1 106例。放血疗法能够提高小儿发热的临床疗效［OR=4.18，95% CI（3.00，5.38），P＜0.001］；降低患儿24 h内高热复发率［OR=0.12，95% CI（0.05，0.34），P＜0.001］；缩短平均退热时间［MD=-1.78，95% CI（-2.56，-1.00），P＜0.001］。结论 放血疗法能够提高小儿发热的临床疗效，降低复发率，缩短退热时间，可作为小儿发热的辅助治疗方法。
Objective To explore the efficacy of bloodletting therapy treatment on pediatric fever by meta-analysis．Methods The randomised controlled trials（RCTs）examining bloodletting therapy for paediatric fever were retrieved from eight Chinese and English databases—China Biomedical Literature Database（CBM），CNKI，Wanfang，VIP，PubMed，Embase，Web of Science，and Cochrane Library—covering publications from the establishment of each database up to May 2025．Two researchers assessed study quality using the risk of bias assessment tool recommended in the Cochrane Handbook for Systematic Reviews（version 5.1.0）．RevMan 5.4 software was employed for systematic analysis of included studies．Results Nineteen RCTs involving 2 224 patients were ultimately included，comprising 1 118 patients in the observation group and 1 106 in the control group．Results indicated that bloodletting therapy significantly improved clinical efficacy in paediatric fever（OR=4.18，95% CI［3.00，5.38］，P＜0.001），reduced the recurrence rate of high fever within 24 hours（OR=0.12，95% CI［0.05，0.34］，P＜0.001），and shortened the average time to fever resolution（MD=-1.78，95% CI［-2.56，-1.00］，P＜0.001）．Conclusions Bloodletting therapy can improve the clinical efficacy of pediatric fever，reduce the recurrence rate and shorten the time of fever reduction，and can be used as an adjunctive treatment for pediatric fever．
目的 利用靶向二代测序技术探究天津市发热呼吸道症候群病原特征,分析病原流行特征,总结规律,为发热伴呼吸道症候群患者治疗策略提供指导。方法 收集2023年1月—2023年12月天津地区某四家医院初诊为发热伴呼吸道症候群的4 039例病例,通过tNGS技术检测,分析鉴定病原微生物,研究不同标本类型病原微生物分布、年龄分布、性别分布、不同时间季节感染分布、微生物类型分布趋势等。结果 4 039例经tNGS技术检测,共检测出90种潜在病原体,总阳性率为94.80%（3 829/4 039）。包括36种细菌、29种病毒、5种非典型病原体和20种真菌。不同种类病原体检出频次排序：革兰阴性细菌（G-细菌）>RNA病毒>DNA病毒>革兰阳性细菌（G+细菌）>真菌>非典型病原体。男女性别阳性检出率比较差异无统计学意义（χ2=0.249,P=0.618）;不同年龄段人群病原体谱有异质性,且阳性患者多分布在0~10岁和>60岁,阳性也集中在该两类人群,阳性率分别为47.90%（1 834/3 829）和31.24%（1 196/3 829）。在单一感染中,肺炎支原体占比最高,为4.91%,其次为新型冠状病毒,占1.59%,再次为呼吸道合胞病毒,占1.23%。不同季节不同感染类型具有差异,整体呈现夏冬季混合感染率高的特点,即夏季新冠病毒合并细菌（鲍曼不动杆菌、肺炎链球菌）,冬季肺炎支原体合并甲型、乙型流感病毒多见。肺炎支原体对大环内酯类药物耐药率随月份呈现增加趋势。结论 tNGS 技术在天津市发热呼吸道症候群样本中获得了较高的病原体检出率,病原体覆盖面广,通过提供更多的病原体信息,可以有效辅助鉴别混合感染和耐药信息。
Objective Using targeted next-generation sequencing technology to explore the composition of the pathogenic spectrum of febrile respiratory syndrome ,analyze the epidemic characteristics of the pathogen,summarize the rules,and provide accurate guidance for the treatment strategy of patients with febrile respiratory syndrome．Methods By tNGS detection of 4039 cases with fever with respiratory diseases in four hospitals in Tianjin in 2023,pathogenic microorganisms were analyzed and identified,and the distribution of pathogenic microorganisms,age distribution,gender distribution,infection distribution in different times and seasons,and distribution trend of microbial types in different specimen types were studied．Results In 4039 cases,90 potential pathogens were detected,the total positive rate was 94.80%（3 829/4 039）,including 36 kinds of bacteria,29 kinds of viruses,5 kinds of atypical pathogen and 6 kinds of fungi．The order of detection frequency of different types of pathogens：G-bacteria > RNA virus > DNA virus > G+ bacteria > fungi > atypical pathogens．There was no significant difference in the positive rate of male and female between the two groups（χ2=0.249,P=0.618）．The pathogen spectrum of different age groups was heterogeneous． The positive patients were mostly distributed in 0-10 years old [47.90%（1 834/3 829）] and >60 years old [31.23%（1 196/3 829）]．Among the single infection,Mycoplasma pneumoniae accounted for the highest proportion,4.91%（188/3829）,followed by 2019-nCoV,1.59%（61/3 829）,and respiratory syncytial virus,1.23%（47/3 829）．There were differences in different infection types in different seasons,and the overall characteristics of mixed infection rate in summer and winter were high． In summer,the new coronavirus was combined with bacteria（Acinetobacter baumannii,Streptococcus pneumoniae）,and in winter,Mycoplasma pneumoniae was combined with influenza A and B viruses．The resistance rate of Mycoplasma pneumoniae to macrolides showed an increasing trend with the time．Conclusions The tNGS technology had obtained a high pathogen detection rate in the samples of febrile respiratory syndrome in Tianjin．By providing more pathogen information,it can be effectively applied to the etiological diagnosis of respiratory infectious diseases and assist in the identification of mixed infections and drug resistance information．
目的 探讨腰-硬联合阻滞分娩镇痛方式对初产妇在产程进展及产时发热的影响,为临床实践提供理论依据。方法 回顾性分析2020年12月—2021年12月在广州市某三甲医院产科分娩产妇535例的基本资料。观察组（285例）采用腰-硬联合阻滞麻醉分娩镇痛,对照组（250例）选择常规无干预分娩。结果 观察组中的产妇第一产程和第二产程的时间比对照组更长,且产后2 h出血量高于对照组,差异有统计学意义（P<0.05）,除此之外,2组产妇产时发热率比较差异也有统计学意义（P<0.01）。结论 腰硬联合阻滞分娩镇痛在一定程度上会延长产程,且产后2 h的出血量较多,同时也会增加产时发热的概率,存在一定不良反应,故需要密切观察,保证母儿安全。
Objective To investigate the effect of combined spinal-epidural block anesthesia on the progress of labor and intrapartum fever in primipara,and to provide a theoretical basis for clinical practice．Methods The basic data of 535 pregnant women who gave birth in the obstetrics department of a tertiary hospital in Guangzhou from December 2020 to December 2021 were retrospectively analyzed．The observation group（285 cases）was given labor analgesia,and the control group（250 cases）was given routine non-intervention delivery．Results The time of the first stage of labor and the second stage of labor in the observation group was significantly longer than that in the control group,and the bleeding volume 2 hours after delivery was higher than that in the control group,and the difference was statistically significant（P<0.05）．The maternal fever rate during delivery also had statistical significance（P<0.01）．Conclusions Combined spinal-epidural block anesthesia will prolong the labor process to a certain extent,and the amount of bleeding in 2 hours after delivery will be more,and it will also increase the probability of intrapartum fever,with certain adverse reactions．Therefore,close observation is needed to ensure the mother and child safety．
