| 1 | 大气二氧化氮与每日总死亡率、心血管和呼吸系统疾病死亡率的短期关联:398个城市的多中心分析显示文摘目的:采用统一的分析方案,评估全球多个国家/地区的二氧化氮(NO_(2))与总死亡率、心血管和呼吸系统疾病死亡率之间的短期关联。研究设计:采用两阶段的时间序列分析方法、过度离散的广义线性模型和多水平meta分析。研究地点:22个低到高收入国家/地区的398个城市。主要结局指标:1973—2018年逐日总死亡人数(6280万人)、心血管疾病死亡人数(1970万人)和呼吸系统疾病死亡人数(550万人)。结果:平均而言,NO_(2)浓度在滞后1天(前1天)每增加10μg/m^(3),会导致总死亡率、心血管和呼吸系统疾病死亡率分别增加0.46%(95%可信区间0.36%~0.57%)、0.37%(0.22%~0.51%)、0.47%(0.21%~0.72%)。在对共污染物(PM_(10)、PM_(2.5)、臭氧、二氧化硫和一氧化碳)进行调整后,这些关联仍然很稳定。所有3种死因的暴露-反应曲线几乎是线性的,没有明显的阈值。在398个城市中,可归因于高过假定零水平的NO_(2)浓度造成的死亡比例为1.23%(95%可信区间0.96%~1.51%)。结论:这项多中心研究提供了关于NO_(2)短期暴露与总死亡率、心血管和呼吸系统死亡风险之间的独立和线性关联的关键证据,说明通过加强NO_(2)的控制和监管限制标准,可获得人群水平的健康收益。 | 孟夏 刘聪(校) 陈仁杰 郑湃(译) 阚海东(校) Francesco Sera Ana Vicedo-Cabrera Ai Milojevic Maria Guo Yuming Tong Shilu Micheline de Sousa Zanotti Stagliorio Coelh Paulo Hilario Nascimento Saldiva Eric Lavigne Patricia Matus Correa Nicolas Valdes Ortega Samuel Osorio Garcia Jan Kysely Ales Urban Hans Orru Marek Maasikmets Jouni J K Jaakkola Niilo Ryti Veronika Huber Alexandra Schneider Klea Katsouyanni Antonis Analitis Masahiro Hashizume Yasushi Honda Chris Fook Sheng Ng Baltazar Nunes João Paulo Teixeira Iulian Horia Holobaca Simona Fratianni Ho Kim Aurelio Tobias Carmeníniguez Bertil Forsberg ChristoferÅström Martina S Ragettli Yue-Liang Leon Guo Shih-Chun Pan Shanshan Li Michelle L Bell Antonella Zanobetti Joel Schwartz Tangchun Wu Antonio Gasparrini | 2021 | 英国医学杂志中文版2021，24，8： | 7 |
| 2 | hsa-miR-29c and hsa-miR-135b differential expression aspotential biomarker of gastric carcinogenesis显示文摘AIM: To investigate the expression profiles of hsa-mi R-29 c and hsa-mi R-135 b in gastric mucosal samples and their values as gastric carcinogenesis biomarkers. METHODS: The expression levels of hsa-mi R-29 c and hsa-mi R-135 b in normal gastric mucosa, non-atrophic chronic gastritis, intestinal metaplasia and intestinaltype gastric adenocarcinoma were analysed using quantitative real-time PCR. The difference between hsa-mi R-29 c and hsa-mi R-135 b expression profiles in the grouped samples was evaluated by ANOVA and Student's t-test tests. The results were adjusted for multiple testing by using Bonferroni's correction. P values ≤ 0.05 were considered statistically significant. To evaluate hsa-mi R-29 c and hsa-mi R-135 b expressions as potential biomarkers of gastric carcinogenesis, we performed a receiver operating characteristic curve analysis and the derived area under the curve, and a Categorical Principal Components Analysis. In silico identification of the genetic targets of hsa-mi R-29 c and hsa-mi R-135 b was performed using different prediction tools, in order to identify possible genes involved in gastric carcinogenesis.RESULTS: The expression levels of hsa-mi R-29 c were higher in normal gastric mucosal samples, and decreased progressively in non-atrophic chronic gastritis samples, intestinal metaplasia samples and intestinal-type gastric adenocarcinoma samples. The expression of hsa-mi R-29 c in the gastric lesions showed that non-atrophic gastritis have an intermediate profile to gastric normal mucosa and intestinal-type gastric adenocarcinoma, and that intestinal metaplasia samples presented an expression pattern similar to that in intestinal-type gastric adenocarcinoma. This micro RNA(mi RNA) has a good discriminatory accuracy between normal gastric samples and(1) intestinal-type gastric adenocarcinoma; and(2) intestinal metaplasia, and regulates the DMNT3 A oncogene. hsa-mi R-135 b is up-regulated in non-atrophic chronic gastritis and intestinal metaplasia samples and down-regulated in normal gastric mucosa and intestinal-type gastric adenocarcinoma samples. Non-atrophic chronic gastritis and intestinal metaplasia are significantly different from normal gastric mucosa samples. hsa-mi R-135 b expression presented a greater discriminatory accuracy between normal samples and gastric lesions. This mi RNA was associated with Helicobacter pylori presence in non-atrophic chronic gastritis samples and regulates the APC and KLF4 tumour suppressor genes.CONCLUSION: Our results provide evidence of epigenetic alterations in non-atrophic chronic gastritis and intestinal metaplasia and suggest that hsa-mi R-29 c and hsa-mi R-135 b are promising biomarkers of gastric carcinogenesis. | Amanda Ferreira Vidal Aline MP Cruz Leandro Magalhães Adenilson L Pereira Ana KM Anaissi Nélisson CF Alves Paulo JBS Albuquerque Rommel MR Burbano Samia Demachki Ândrea Ribeiro-dos-Santos | 2016 | World Journal of Gastroenterology2016，22，6： | 7 |
| 3 | Circulating leptin and its muscle gene expression in Nellore cattle with divergent feed efficiency显示文摘Background: Leptin has a strong relation to important traits in animal production, such as carcass composition,feed intake, and reproduction. It is mainly produced by adipose cells and acts predominantly in the hypothalamus.In this study, circulating leptin and its gene expression in muscle were evaluated in two groups of young Nellore bulls with divergent feed efficiency. Individual dry matter intake(DMI) and average daily gain(ADG) of 98 Nellore bulls were evaluated in feedlot for 70 d to determinate the residual feed intake(RFI) and select 20 animals for the high feed efficient(LRFI) and 20 for the low feed efficient(HRFI) groups. Blood samples were collected on d 56 and at slaughter(80 d) to determine circulating plasma leptin. Samples of Longissimus dorsi were taken at slaughter for leptin gene expression levels.Results: DMI and RFI were different between groups and LRFI animals showed less back fat and rump fat thickness,as well as less pelvic and kidney fat weight. Circulating leptin increased over time in all animals. Plasma leptin was greater in LRFI on 56 d and at slaughter(P = 0.0049). Gene expression of leptin were greater in LRFI animals(P = 0.0022) in accordance with the plasma levels. The animals of the LRFI group were leaner, ate less, and had more circulating leptin and its gene expression.Conclusion: These findings demonstrated that leptin plays its physiological role in young Nellore bulls, probably controlling food intake because feed efficient animals have more leptin and lower residual feed intake. | Lúcio Flávio Macedo Mota Cristina Moreira Bonafé Pamela Almeida Alexandre Miguel Henrique Santana Francisco JoséNovais Erika Toriyama Aldrin Vieira Pires Saulo da Luz Silva Paulo Roberto Leme JoséBento Sterman Ferraz Heidge Fukumasu | 2018 | Journal of Animal Science and Biotechnology2018，9，1： | 3 |
| 4 | Papillary fistulotomy vs conventional cannulation for endoscopic biliary access:A prospective randomized trial显示文摘AIM To compare the cannulation success, biochemical profile, and complications of the papillary fistulotomy technique vs catheter and guidewire standard access.METHODS From July 2010 to May 2017, patients were prospectively randomized into two groups: Cannulation with a catheter and guidewire(Group Ⅰ) and papillary fistulotomy(Group Ⅱ). Amylase, lipase and C-reactive protein at T0, as well as 12 h and 24 h after endoscopic retrograde cholangiopancreatography, and complications(pancreatitis, bleeding, perforation) were recorded.RESULTS We included 102 patients(66 females and 36 males, mean age 59.11 ± 18.7 years). Group Ⅰ and Group Ⅱ had 51 patients each. The successful cannulation rates were 76.5% and 100%, respectively(P = 0.0002). Twelve patients(23.5%) in Group Ⅰ had a difficult cannulation and underwent fistulotomy, which led to successful secondary biliary access(Failure Group). The complication rate was 13.7%(2 perforations and 5 mild pancreatitis) vs 2.0%(1 patient with perforation and pancreatitis) in Groups Ⅰ and Ⅱ, respectively(P = 0.0597). CONCLUSION Papillary fistulotomy was more effective than guidewire cannulation, and it was associated with a lower profile of amylase and lipase. Complications were similar in both groups. | Carlos Kiyoshi Furuya Paulo Sakai Fabio Ramalho Tavares Marinho Jose Pinhata Otoch Spencer Cheng Lívia Lemes Prudencio Eduardo Guimaraes Hourneaux de Moura Everson Luiz de Almeida Artifon | 2018 | World Journal of Gastroenterology2018，24，16： | 2 |
| 5 | Evaluation of biodegradable electric conductive tube-guides and mesenchymal stem cells显示文摘AIM: To study the therapeutic effect of three tubeguides with electrical conductivity associated to mesenchymal stem cells(MSCs) on neuro-muscular regeneration after neurotmesis.METHODS: Rats with 10-mm gap nerve injury were tested using polyvinyl alcohol(PVA), PVA-carbon nanotubes(CNTs) and MSCs, and PVA-polypyrrole(PPy). The regenerated nerves and tibialis anterior muscles were processed for stereological studies after 20 wk. The functional recovery was assessed serially for gait biomechanical analysis, by extensor postural thrust, sciatic functional index and static sciatic functionalindex(SSI), and by withdrawal reflex latency(WRL). In vitro studies included cytocompatibility, flow cytometry, reverse transcriptase polymerase chain reaction and karyotype analysis of the MSCs. Histopathology of lung, liver, kidneys, and regional lymph nodes ensured the biomaterials biocompatibility. RESULTS: SSI remained negative throughout and independently from treatment. Differences between treted groups in the severity of changes in WRL existed, showing a faster regeneration for PVA-CNTs-MSCs(P < 0.05). At toe-off, less acute ankle joint angles were seen for PVA-CNTs-MSCs group(P = 0.051) suggesting improved ankle muscles function during the push off phase of the gait cycle. In PVA-PPy and PVA-CNTs groups, there was a 25% and 42% increase of average fiber area and a 13% and 21% increase of the 'minimal Feret's diameter' respectively. Stereological analysis disclosed a significantly(P < 0.05) increased myelin thickness(M), ratio myelin thickness/axon diameter(M/d) and ratio axon diameter/fiber diameter(d/D; g-ratio) in PVA-CNT-MSCs group(P < 0.05). CONCLUSION: Results revealed that treatment with MSCs and PVA-CNTs tube-guides induced better nerve fiber regeneration. Functional and kinematics analysis revealed positive synergistic effects brought by MSCs and PVA-CNTs. The PVA-CNTs and PVA-PPy are promising scaffolds with electric conductive properties, bio- and cytocompatible that might prevent the secondary neurogenic muscular atrophy by improving the reestablishment of the neuro-muscular junction. | Jorge Ribeiro Tiago Pereira Ana Rita Caseiro Paulo Armada-da-Silva Isabel Pires Justina Prada Irina Amorim Sandra Amado Miguel Franca Carolina Goncalves Maria Ascensao Lopes Jose Domingos Santos Dina Morais Silva Stefano Geuna Ana Lúcia Luís Ana Colette Maurício | 2015 | World Journal of Stem Cells2015，7，6： | 2 |
| 6 | Comparison between hepaticojejunostomy and hepaticoduodenostomy after excision of choledochal cyst in children:a cohort study显示文摘Objective Hepaticojejunostomy(HJ)and hepaticoduodenostomy(HD)are commonly used biliary reconstruction techniques after choledochal cyst excision.HD has been suggested to be a more physiologic alternative during reconstruction.The objective of this study is to compare operative time,hospital stay,morbidity(leak,cholangitis,ileus,and obstruction),and mortality between HJ and HD after cyst excision.Methods This is a 14-year retrospective cohort study of pediatric patients(≤18 years old)who underwent choledochal cyst excision and subsequent biliary reconstruction at the Philippine Children’s Medical Center.Data were taken from inpatient charts,operative technique,OPD logbook,readmission,and OPD charts.results There were 122 patients:56%HD and 44%HJ.Majority were female(72%),with 1:2.6 male to female ratio.The average age was 36.1 months,with a mean follow-up of 32.8 months(range 6 months-14 years).The most common cyst was type I(87%).Operative time was longer for HJ compared with HD(321.3 vs 203.6 min;p=0.000).Hospital stay was longer with HJ compared with HD(7.7 vs 6.8 days;p=0.002).Mortality rate was low at 1.6%while morbidity was at 13.9%in both groups.Although morbidity was higher among those who underwent HD,there was no significant difference between the two procedures.Anastomotic leak(4%)and cholangitis(7.4%)were observed in HD,and ileus(7.4%)was observed in the HJ group.Conclusions In our series,HD provided less operative time and hospital stay than with HJ.We did not observe bile gastritis after HD as compared with others.It is suggested that longer follow-up is needed to confirm such findings. | Johann Paulo Suico Guzman Leandro L Resurreccion III Marcus Lester R Suntay Renato G Bernaldez | 2019 | World Journal of Pediatric Surgery2019，2，2： | 2 |
| 7 | Juvenile hemochromatosis:HAMP mutation and severe iron overload treated with phlebotomies and deferasirox显示文摘Juvenile hemochromatosis(JH) is a rare condition classified as an autosomal recessive disorder that leads to severe iron absorption. JH usually affects people under the age of 30 and presents symptoms such as chronic liver damage,hypogonadotropic hypogonadism,cardiac diseases and endocrine dysfunctions. The present case reports a 29-year-old Brazilian woman with JH condition due to HAMP mutation(g.47G>A),treated with phlebotomies and deferasirox. She presented symptoms such as weakness,skin hyperpigmentation,joint pain in the shoulders and hands and amenorrhea. First laboratory tests showed altered biochemical parameters [serum ferritin(SF): 5696 ng/mL,transferrin saturation(TS): 85%]. After sessions of phlebotomies(450 mL every 15 d),the patient presented partial symptomatic improvements and biochemical parameters(SF: 1000 ng/mL,Hb: 11 g/dL). One year later,deferasirox(15 mg/kg per day) was introduced to the treatment,and the patient showed total symptomatic improvement,with significant clearing of the skin,SF: 169 ng/mL,and TS: 50%. Furthermore,after the combined deferasirox-phlebotomy therapy,magnetic resonance imaging measurements revealed normalized level for liver iron(30 μmol/g; reference value < 36 μmol/g). In conclusion,combined deferasirox-phlebotomy treatment was able to normalize iron levels and improve symptoms. | Manuel A Lescano Letícia C Tavares Paulo C J L Santos | 2017 | World Journal of Clinical Cases2017，5，10： | 2 |
| 8 | sTWEAK is a marker of early haematoma growth and leukoaraiosis in intracerebral haemorrhage显示文摘Objective To study the association between early growth of haematoma with biomarkers of endothelial dysfunction such as leukoaraiosis(LA)and the soluble tumour necrosis factor-like weak inducer of apoptosis(sTWEAK)in patients with intracerebral haemorrhage(ICH).Methods This is a retrospective observational study of patients with nontraumatic ICH.Clinical and biochemical parameters were analysed.sTWEAK levels were measured by ELISA.LA was analysed in the hemisphere without haemorrhage to avoid interference with the acute injury.The main endpoint was the haematoma growth evaluated by the difference in volume between the second and the initial neuroimage.Poor functional outcome,defined as a modified Rankin Scale>2 at 3 months,was considered as secondary endpoint.Receiver operating characteristic curve analysis was performed to stablish the best cut-off for sTWEAK levels associated with haematoma growth.Results We included 653 patients with ICH in our analysis(71.1±11.9 years,44%women).Haematoma growth was observed in 188 patients(28.8%).sTWEAK levels≥5600 pg/mL predicted ICH growth with a sensitivity of 84%and a specificity of 87%.sTWEAK levels≥5600 pg/mL and the presence of LA were associated with haematoma growth(OR:42.46;(CI 95%22.67 to 79.52)and OR:2.73(CI 95%1.39 to 5.34),respectively).Also,the presence of LA(OR:4.31(CI 95%2.89 to 6.42))and the interaction between ICH growth and sTWEAK(OR:2.23(CI 95%1.40 to 3.55))were associated with poor functional outcome at 3 months.Conclusion sTWEAKs,together with the presence and grade of LA,are biomarkers able to predict ICH growth and poor functional outcome in patients with ICH. | Andrés da Silva-Candal Iria López-Dequidt Manuel Rodriguez-Yañez PauloÁvila-Gómez JoséManuel Pumar JoséCastillo Tomás Sobrino Francisco Campos Ramón Iglesias-Rey Pablo Hervella | 2021 | Stroke & Vascular Neurology2021，6，4： | 2 |
