| 8 | Pediatric functional constipation treatment with Bifi dobacterium-containing yogurt:A crossover,double-blind,controlled trial显示文摘AIM: To evaluate the treatment of pediatric functional chronic intestinal constipation (FCIC) with a probiotic goat yogurt. METHODS: A crossover double-blind formula-controlled trial was carried out on 59 students (age range: 5-15 years) of a public school in Belo Horizonte, MG, Brazil, presenting a FCIC diagnostic, according to Roma Ⅲ criteria. The students were randomized in two groups to receive a goat yogurt supplemented with 109 colony forming unit/mL Bifidobacterium longum (B.longum) (probiotic) daily or only the yogurt for a period of 5 wk (formula). Afterwards, the groups were intercrossed for another 5 wk. Defecation frequency, stool consistency and abdominal and defecation pain were assessed.RESULTS: Both treatment groups demonstrated improvement in defecation frequency compared to baseline. However, the group treated with probiotic showed most signif icant improvement in the f irst phase of the study. An inversion was observed after crossing over, resulting in a reduction in stool frequency when this group was treated by formula. Probiotic and formula improved stool consistency in the f irst phase of treatment, but the improvement obtained with probiotic was significantly higher (P = 0.03). In the second phase of treatment, the group initially treated with probiotic showed worseningstool consistency when using formula. However, the difference was not signif icant. A signif icant improvement in abdominal pain and defecation pain was observed with both probiotic and formula in the first phase of treatment, but again the improvement was more signif icant for the group treated with B. longum during phase I (P < 0.05). When all data of the crossover study were analyzed, significant differences were observed between probiotic yogurt and yogurt only for defecation frequency (P = 0.012), defecation pain (P = 0.046) and abdominal pain (P = 0.015). | Paula VP Guerra Luiza N Lima Tassia C Souza Vanessa Mazochi Francisco J Penna Andreia M Silva Jacques R Nicoli Elizabet V Guimares | 2011 | World Journal of Gastroenterology2011,17,34: | 25 |
| 9 | 2018加拿大心境障碍与焦虑障碍治疗协作组/国际双相障碍学会指南:双相障碍的管理显示文摘加拿大心境障碍与焦虑障碍治疗协作组(Canadian Network for Mood and Anxiety Treatments,CANMAT)曾于2005年发布了第1版双相障碍管理指南,并分别于2007、2009和2013年对该指南进行了更新,其中最近的2次更新是与国际双相障碍学会(International Society for Bipolar Disorders,ISBD)合作完成。2018版CANMAT/ISBD双相障碍治疗指南(以下简称指南)反映了自2005年首版指南发表以来本领域取得的重大进展,包括疾病诊断与疾病管理的更新以及药物治疗与心理治疗的近期研究进展。这些前沿进展中综合考虑了循证证据的级别,并基于治疗疗效、临床实践经验、安全性、耐受性和药物导致的转相风险等,对一线、二线及三线治疗方案进行了简明而清晰的推荐。本指南中新增内容涵盖了双相Ⅰ型障碍(BD-Ⅰ)的躁狂发作急性期、抑郁发作急性期和双相障碍维持期的一线及二线治疗推荐等级划分。这种对治疗推荐等级的划分综合考虑了治疗方法对双相障碍不同时相的影响,将进一步帮助临床医生做出基于循证证据的治疗决策。锂盐、喹硫平、双丙戊酸盐、阿塞那平、阿立哌唑、帕利哌酮、利培酮和卡利拉嗪单药或联合使用被推荐为躁狂发作急性期的一线治疗选择。BD-Ⅰ抑郁期的一线治疗选择包括喹硫平、鲁拉西酮、锂盐、拉莫三嗪单药,鲁拉西酮联合锂盐或双丙戊酸盐或拉莫三嗪辅助治疗。尽管急性期治疗有效的药物通常应继续用于BD-Ⅰ的维持期治疗,但也存在一些特殊情况(例如抗抑郁药)。现有数据表明,锂盐、喹硫平、双丙戊酸盐、拉莫三嗪、阿塞那平和阿立哌唑单药或联合治疗应被视为维持治疗的初始或更换治疗方案时的一线选择。除了探讨BD-Ⅰ的相关问题外,本指南中还对双相Ⅱ型障碍(BD-Ⅱ)的临床管理进行了系统回顾并给予治疗推荐,同时针对特殊人群也有相关推荐,如处于各个生殖周期的女性、儿童、青少年和老年人。此外,本指南中还讨论了特定精神疾病及共病(如物质滥用、焦虑障碍和代谢性疾病)的影响。最后,本指南中概述了安全性和药物监测的相关问题。CANMAT/ISBD工作组希望本指南能够成为全球临床医生的实用工具。 | Lakshmi N Yatham Sidney H Kennedy Sagar V Parikh Ayal Sehaffer David J Bond Benicio N Frey Verinder Sharma Benjamin I Goldstein Soham Rej Serge Beaulieu Martin Alda Glenda MaeQueen Roumen V Milev Arun Ravindran Claire O'Donovan Diane Mclntosh Raymond W Lam Gustavo Vazquez Flavio Kapczinski Roger S Melntyre Jan Kozicky Shigenobu Kanba Beny Lafer Trisha Suppes Joseph R Calabrese Eduard Vieta Gin Malhi Robert M Post Michael Berk 胡晨(译) 王刚(译) | 2019 | 中华精神科杂志2019,52,1: | 25 |
| 10 | A matched-pair analysis of laparoscopic versus open pancreaticoduodenectomy: oncological outcomes using Leeds Pathology Protocol显示文摘BACKGROUND: Laparoscopic pancreaticoduodenectomy(LPD)is a safe procedure. Oncological safety of LPD is still a matter for debate. This study aimed to compare the oncological outcomes,in terms of adequacy of resection and recurrence rate following LPD and open pancreaticoduodenectomy(OPD).METHODS: Between November 2005 and April 2009, 12LPDs(9 ampullary and 3 distal common bile duct tumors)were performed. A cohort of 12 OPDs were matched for age,gender, body mass index(BMI) and American Society of Anesthesiologists(ASA) score and tumor site.RESULTS: Mean tumor size LPD vs OPD(19.8 vs 19.2 mm,P=0.870). R0 resection was achieved in 9 LPD vs 8 OPD(P=1.000). The mean number of metastatic lymph nodes and total number resected for LPD vs OPD were 1.1 vs 2.1(P=0.140)and 20.7 vs 18.5(P=0.534) respectively. Clavien complications grade I/II(5 vs 8), III/IV(2 vs 6) and pancreatic leak(2 vs 1)were statistically not significant(LPD vs OPD). The mean high dependency unit(HDU) stay was longer in OPD(3.7 vs 1.4 days,P<0.001). There were 2 recurrences each in LPD and OPD(logrank,P=0.983). Overall mortality for LPD vs OPD was 3 vs 6(log-rank, P=0.283) and recurrence-related mortality was 2 vs 1.There was one death within 30 days in the OPD group secondary to severe sepsis and none in the LPD group.CONCLUSIONS: Compared to open procedure, LPD achieved a similar rate of R0 resection, lymph node harvest and longterm recurrence for tumors less than 2 cm. Though technically challenging, LPD is safe and does not compromise oncological outcome. | Abdul R Hakeem Caroline S Verbeke Alison Cairns Amer Aldouri Andrew M Smith Krishna V Menon | 2014 | Hepatobiliary & Pancreatic Diseases International2014,13,4: | 24 |

| 12 | Ultra-thin, planar, Babinet-inverted plasmonic metalenses显示文摘We experimentally demonstrate the focusing of visible light with ultra-thin,planar metasurfaces made of concentrically perforated,30-nm-thick gold films.The perforated nano-voids—Babinet-inverted(complementary)nano-antennas—create discrete phase shifts and form a desired wavefront of cross-polarized,scattered light.The signal-to-noise ratio in our complementary nano-antenna design is at least one order of magnitude higher than in previous metallic nano-antenna designs.We first study our proof-of-concept‘metalens’with extremely strong focusing ability:focusing at a distance of only 2.5 mm is achieved experimentally with a 4-mm-diameter lens for light at a wavelength of 676 nm.We then extend our work with one of these‘metalenses’and achieve a wavelength-controllable focal length.Optical characterization of the lens confirms that switching the incident wavelength from 676 to 476 nm changes the focal length from 7 to 10 mm,which opens up new opportunities for tuning and spatially separating light at different wavelengths within small,micrometer-scale areas.All the proposed designs can be embedded on-chip or at the end of an optical fiber.The designs also all work for two orthogonal,linear polarizations of incident light. | Xingjie Ni Satoshi Ishii Alexander V Kildishev Vladimir M Shalaev | 2013 | Light(Science & Applications)2013,2,1: | 20 |
| 13 | Mesenchymal stem cell-derived exosomes promote neurogenesis and cognitive function recovery in a mouse model of Alzheimer’s disease显示文摘Studies have shown that mesenchymal stem cell-derived exosomes can enhance neural plasticity and improve cognitive impairment.The purpose of this study was to investigate the effects of mesenchymal stem cell-derived exosomes on neurogenesis and cognitive capacity in a mouse model of Alzheimer’s disease.Alzheimer’s disease mouse models were established by injection of beta amyloid 1?42 aggregates into dentate gyrus bilaterally.Morris water maze and novel object recognition tests were performed to evaluate mouse cognitive deficits at 14 and 28 days after administration.Afterwards,neurogenesis in the subventricular zone was determined by immunofluorescence using doublecortin and PSA-NCAM antibodies.Results showed that mesenchymal stem cells-derived exosomes stimulated neurogenesis in the subventricular zone and alleviated beta amyloid 1?42-induced cognitive impairment,and these effects are similar to those shown in the mesenchymal stem cells.These findings provide evidence to validate the possibility of developing cell-free therapeutic strategies for Alzheimer’s disease.All procedures and experiments were approved by Institutional Animal Care and Use Committee(CICUAL)(approval No.CICUAL 2016-011)on April 25,2016. | Edwin E.

| 15 | Evaluation of clinical relevance of examining K-ras, p16 and p53 mutations along with allelic losses at 9p and 18q in EUS-guided fine needle aspiration samples of patients with chronic pancreatitis and pancreatic cancer显示文摘AIM: To establish an optimum combination of molecular markers resulting in best overall diagnostic sensitivity and specificity for evaluation of suspicious pancreatic mass. METHODS: Endoscopic ultrasound (EUS)-guided fine needle aspiration cytology (FNA) was performed on 101 consecutive patients (63 males, 38 females, 60 ± 12 years; 81 with subsequently diagnosed pancreatic cancer, 20 with chronic pancreatitis) with focal pancreatic mass. Samples were evaluated on-site by an experienced cytopathologist. DNA was extracted from Giemsa stained cells selected by laser microdissection and the presence of K-ras, p53 and p16 somatic mutations was tested by cycling-gradient capillary electrophoresis (CGCE) and single-strand conformation polymorphism (SSCP) techniques. In addition, allelic losses of tumor suppressor genes p16 (INK4, CDKN2A) and DPC4 (MADH4, SMAD4) were detected by monitoring the loss of heterozygosity (LOH) at 9p and 18q, respectively. RESULTS: Sensitivity and specificity of EUS-guided FNA were 75% and 85%, positive and negative predictivevalue reached 100%. The remaining 26% samples were assigned as inconclusive. Testing of molecular markers revealed sensitivity and specificity of 70% and 100% for K-ras mutations (P < 0.001), 24% and 90% for p53 mutations (NS), 13% and 100% for p16 mutations (NS), 85% and 64% for allelic losses at 9p (P < 0.001) and 78% and 57% for allelic losses at 18q (P < 0.05). When tests for different molecular markers were combined, the best results were obtained with K-ras + LOH at 9p (92% and 64%, P < 0.001), K-ras + LOH at 18q (92% and 57%, P < 0.001), and K-ras + LOH 9q + LOH 18q (96% and 43%, P < 0.001). When the molecular markers were used as complements to FNA cytology to evaluate inconclusive samples only, the overall sensitivity of cancer detection was 100% in all patients enrolled in the study. CONCLUSION: EUS-guided FNA cytology combined with screening of K-ras mutations and allelic losses of tumor suppressors p16 and DPC4 represents a very sensitive approach in screening for pancreatic malignancy. Molecular markers may find its use particularly in cases where FNA cytology has been inconclusive. | C Salek L Benesova M Zavoral V Nosek L Kasperova M Ryska R Strnad E Traboulsi M Minarik | 2007 | World Journal of Gastroenterology2007,13,27: | 18 |

| 17 | Targeting of the AKT/m-TOR Pathway: Biomarkers of Resistance to Cancer Therapy——AKT/m-TOR Pathway and Resistance to Cancer Therapy显示文摘Resistance to cancer therapy continues to be a major limitation for the successful treatment of cancer. There are many published studies on therapy resistance in breast and prostate cancers; however, there are currently no data on molecular markers associated with resistance. The conflicting data were reported regarding the AKT/m-TOR signaling pathway components as markers predicting resistance. The AKT/m-TOR signaling pathway is involved in the development of many human cancers; its activation is related to cell proliferation, angiogenesis, apoptosis, as well as to therapy resistance. Molecular alterations in the AKT/m-TOR signaling pathway provide a platform to identify universal markers associated with the development of resistance to cancer therapy. | Liudmila V SPIRINA Irina V KONDAKOVA Natalia V TARASENKO Elena M SLONIMSKAYA Evgeny A USYNIN Alexey K GORBUNOV Zahar A YURMAZOV Svetlana Yu CHIGEVSKAYA | 2018 | 中国肺癌杂志2018,21,1: | 18 |
| 18 | Visceral hypersensitivity and electromechanical dysfunction as therapeutic targets in pediatric functional dyspepsia显示文摘Functional gastrointestinal disorders(FGID) are common clinical syndromes diagnosed in the absence of biochemical,structural,or metabolic abnormalities. They account for significant morbidity and health care expenditures and are identifiable across variable age,geography,and culture. Etiology of abdominal pain associated FGIDs,including functional dyspepsia(FD),remains incompletely understood,but growing evidence implicates the importance of visceral hypersensitivity and electromechanical dysfunction. This manuscript explores data supporting the role of visceral hypersensitivity and electromechanical dysfunction in FD,with focus on pediatric data when available,and provides a summary of potential therapeutic targets. | John M Rosen Jose T Cocjin Jennifer V Schurman Jennifer M Colombo Craig A Friesen | 2014 | World Journal of Gastrointestinal Pharmacology and Therapeutics2014,5,3: | 16 |
| 19 | Phytochemical and anti-bacterial activity of epidermal glands extract of Christella parasitica (L.) H. Lev.显示文摘Objective:To study the morphology,biochemistry and bioactivity of the epidermal glands of the glandular morphotype of Christella parasitica(C.parasitica)(L.) H.Lev.Methods: Morphological studies on epidermal glands were earned out by using light microscope and scanning electron microscope.To prepare the extract,the shade-dried fronds of glandular morphotype were soaked in acetone.For antibacterial studies paper disc method was followed by using various pathogenic bacteria.Results:Detailed micromorphological,phytochemical and bioactivity studies on a medicinal fern C.parasitica(L.) H.Lev.showed its inlraspecific variation in antibacterial activity.The presence or absence of the epidermal glands was the key factor for antibacterial activity in the morphovariants of this species.The epidermal glands were orange-coloured,stalked and elongated ones of about 84.2μm×45μm,and distributed on the undersurface of cosla,coslules and veins in croziers,young and mature leaves.Frequency of glands varied from 15/cm on costa in mature leaves to 140/cm on costules in croziers.The acetone extract of the glands showed antibacterial activities and also toxic effect against mosquito larvae and tadpoles of frog.Preliminary phytochemical analysis and HPLC studies of the gland extract showed the presence of various kinds of terpenoids,alkaloids,tannins,saponins and flavonoids in it.Conclusions:The present study shows that epidermal glands of the glandular morphotype of C. parasitica(L.) H.Lev.have several bioactive compounds and such rare moiphovariant should be conserved in nature.The next step is to isolate the pure compounds and to screen the bioactivity of individual compounds of the epidermal glands. | Paul Raj K Irudayaraj V Johnson M Patric Raja D | 2011 | Asian Pacific Journal of Tropical Biomedicine2011,1,1: | 14 |
