The occurrence of obesity has increased across the whole world. Many epidemiological studies have indicated that obesity strongly contributes to the development of cancer, cardiovascular diseases, type 2 diabetes, liver diseases and other disorders, accounting for a heavy burden on the public and on health-care systems every year. Excess energy uptake induces adipocyte hypertrophy, hyperplasia and formation of visceral fat in other non-adipose tissues to evoke cardiovascular disease, liver diseases. Adipose tissue can also secrete adipokines and inflammatory cytokines to affect the local microenvironment,induce insulin resistance, hyperglycemia, and activate associated inflammatory signaling pathways. This further exacerbates the development and progression of obesity-associated diseases. Although some progress in the treatment of obesity has been achieved in preclinical and clinical studies, the progression and pathogenesis of obesity-induced diseases are complex and unclear. We still need to understand their links to better guide the treatment of obesity and associated diseases. In this review, we review the links between obesity and other diseases, with a view to improve the future management and treatment of obesity and its co-morbidities.

目的探讨脂联素(APN)是否可通过PPARα/HOXA10通路改善多囊卵巢综合征(PCOS)大鼠子宫内膜容受性。方法6周龄雌性SD大鼠随机分为对照组(CON,n=10)和PCOS模型组(n=40)。用来曲唑[1 mg/(kg·d)]建立PCOS大鼠模型后,再随机分为4组(n=10):模型对照组(PCOS),APN干预组(PCOS+APN)、APN联合PPARα抑制剂(GW6471)干预组(PCOS+APN+GW)及APN联合玉米油溶剂(vehicle,VEH)对照组(PCOS+APN+VEH);后3组大鼠均给与APN[10μg/(kg·d)]干预20 d。在给APN的第11天,PCOS+APN+GW组同时给与GW6471[1 mg/(kg·d)]作为阴性对照,PCOS+APN+VEH组同时给与vehicle(0.1 mL/d)作为阳性对照。检测大鼠动情周期、卵巢和子宫指数及其形态学变化、血清激素及生化指标的改变。免疫组化和Western blot检测PPARα和HOXA10蛋白的表达,电镜观察子宫内膜胞饮突的发育情况,合笼实验观察大鼠的妊娠情况。结果与CON组比较,PCOS组大鼠动情周期紊乱,多处于动情间期;平均体质量和卵巢指数增加、子宫指数下降(P<0.05),血清激素与脂质代谢异常,卵巢多囊样改变;给与APN干预后各组各项指标均得到恢复。子宫内膜组织中PPARα和HOXA10的表达:在PCOS组较CON组显著下调(P<0.05)、在PCOS+APN组中较PCOS组显著上调(P<0.05)、在PCOS+APN+GW组中较PCOS+APN组及PCOS+APN+VEH组则显著下调(P<0.05)。与CON组比较,PCOS组大鼠子宫内膜胞饮突发育欠佳;PCOS+APN组胞饮突发育较PCOS组良好;与PCOS+APN组比较,PCOS+APN+GW组胞饮突发育欠佳;与PCOS+APN+GW组比较,PCOS+APN+VEH组胞饮突发育良好。与PCOS组比较,各组大鼠妊娠率一致;但PCOS+APN+GW组大鼠胚胎数量相对于PCOS+APN组显著减少且发育迟缓。结论APN可通过上调PPARα/HOXA10通路改善PCOS大鼠子宫内膜容受性,该结果有望为改善PCOS病人妊娠结局的治疗提供实验依据。

Prokaryotes are ubiquitous in the biosphere, important for human health and drive diverse biological and environmental processes. Systematics of prokaryotes, whose origins can be traced to the discovery of microorganisms in the 17th century, has transitioned from a phenotype-based classification to a more comprehensive polyphasic taxonomy and eventually to the current genome-based taxonomic *** transition aligns with a foundational shift from studies focused on phenotypic traits that have limited comparative value to those using genome sequences. In this context, Bergey's Manual of Systematics of Archaea and Bacteria(BMSAB) and Bergey's International Society for Microbial Systematics(BISMiS) play a pivotal role in guiding prokaryotic systematics. This review focuses on the historical development of prokaryotic systematics with a focus on the roles of BMSAB and BISMiS. We also explore significant contributions and achievements by microbiologists, highlight the latest progress in the field and anticipate challenges and opportunities within prokaryotic systematics. Additionally, we outline five focal points of BISMiS that are aimed at addressing these challenges. In conclusion, our collaborative effort seeks to enhance ongoing advancements in prokaryotic systematics, ensuring its continued relevance and innovative characters in the contemporary landscape of genomics and bioinformatics.

目的了解2012—2021年湖南省细菌耐药监测网呼吸道分离菌的分布和耐药性变迁。方法细菌鉴定和药敏试验统一按全国细菌耐药监测网(CARSS)细菌耐药监测技术方案执行,剔除重复菌株。按照美国临床实验室标准化协会(CLSI)2022年标准判断细菌对抗菌药物的敏感性,应用WHONET 5.6软件进行统计描述。结果2012—2021年湖南省细菌耐药监测网呼吸道标本共分离976984株细菌,其中革兰阳性菌185642株(19.0%),革兰阴性菌791342株(81.0%)。分离自成人患者呼吸道标本排名前五位的细菌是肺炎克雷伯菌(25.2%)、铜绿假单胞菌(17.0%)、鲍曼不动杆菌(14.6%)、大肠埃希菌(6.7%)和金黄色葡萄球菌(5.8%)。分离自儿童患者呼吸道标本排名前五位的细菌是金黄色葡萄球菌(17.7%)、肺炎链球菌(15.6%)、大肠埃希菌(13.5%)、肺炎克雷伯菌(13.1%)和流感嗜血杆菌(10.8%)。肺炎克雷伯菌、大肠埃希菌和阴沟肠杆菌对替加环素、头孢哌酮/舒巴坦、哌拉西林/他唑巴坦、碳青霉烯类、阿米卡星耐药率较低(2012—2013年的3.5%、4.2%逐渐上升至2020—2021年的9.5%、11.5%,对头孢哌酮/舒巴坦、哌拉西林/他唑巴坦、阿米卡星、妥布霉素、环丙沙星和左氧氟沙星的耐药率呈上升趋势。大肠埃希菌和阴沟肠杆菌对氨曲南、氨基糖苷类和氟喹诺酮类的耐药率呈下降趋势。铜绿假单胞菌对多黏菌素耐药率较低(208/37594)、22.7%(10874/47882)。结论湖南省2012—2021年呼吸道分离细菌以革兰阴性菌为主,成人和儿童患者分离的优势细菌并不相同。大肠埃希菌、阴沟肠杆菌和铜绿假单胞菌对部分抗菌药物的耐药率不断下降。肺炎克雷伯菌对碳青霉烯类耐药率逐渐上升。应持续高效做好细菌耐药监测,为临床使用抗菌药物提供数据支持。

BACKGROUND： G protein is closely associated with vasomotion. Vasomotor dysfunction accompanies migraine attack. OBJECTIVE： To investigate the effects of the San Jiao meridian acupuncture on G protein content in a rat migraine model. DESIGN, TIME AND SETTING： The present randomized grouping, cellular and molecular biological level trial was performed at the institute of Integrated Traditional Chinese and Western medicine, Xiangya Hospital, Central south University ＆ Key Laboratory for Tumor Proteomics of Ministry of Health between October 2003 and June 2004. MATERIALS： Forty healthy, male, Sprague Dawtey rats were included in this study. The G6805-2A electro-acupuncture apparatus was a product of Shanghai Huayi Medical Instrument Factory, china. Nitroglycerin was produced by Guangzhou Mingxing Pharmaceutical Factory, china. Antibodies against inhibitory and stimulatory G proteins were purchased from Sigma Chemical Company, USA. METHODS： All 40 rats were randomly and evenly divided into 4 groups. In the blank control group, the rats remained untouched. Rats from the normal control group were subcutaneously administered 2 mL/kg physiological saline. In the model group, migraine was induced with a subcutaneous injection of 10 mg/kg nitroglycerin （5 g/L）, and the rats received no further treatment. In the acupuncture-treated group, 30 minutes after migraine induction, acupuncture was performed at the bilateral Waiguan （SJ 5） and Yifeng （SJ 17） points, with an acupuncture depth of 1 mm. Electric-stimulation parameters of 20 Hz for low frequency, 40 Hz for high frequency, and 0.5-1.0 mA for current intensity were set. Ten acupuncture sessions were applied, with 20-minute low-frequency and 20-minute high-frequency stimulation and 3 seconds of interval time. MAIN OUTCOME MEASURES： Inhibitory and stimulatory G protein contents were detected by Western blot analysis. RESULTS： At 4 hours after migraine induction, compared with the blank control and normal control groups stimula

目的建立高效的艾纳香Blumea balsamifera特选种苗克隆技术体系并获得高质量的候选种质。方法特选了通过初筛的3种L-龙脑不同含量(低、中、高)的种质母株,优化组培培养基配方,再比较母株和克隆苗中L-龙脑的含量。结果确定了最佳培养基配方,GC-MS分析证实,克隆苗中L-龙脑的含量与母株呈一致趋势。结论成功地建立了一种保持遗传稳定性的高效组织培养技术。添加适量的胺鲜酯(diethyl aminoethyl hexanoate)可显著提高再生苗的生根效率。研究还表明,所选艾纳香种质(H)中的高L-龙脑含量是由遗传因素决定的,并且高L-龙脑的特性保留在克隆苗的后代中。为艾纳香无性繁殖选育优良种苗提供了宝贵的优质候选种质,具有较好推广前景。
