2Study of the mechanisms of acupuncture and moxibustion treatmentfor ulcerative colitis ratsinview of the gene expression of cytokines显示文摘AIM To observe the effect of acupuncture and moxibustion on the expression of IL 1β and IL 6 mRNA in ulcerative colitis rats. METHODS The SD rat ulcerative colitis model was created by immunological method associated with local stimulation. Colonic mucosa was prepared from human fresh surgical colonic specimens, homogenized by adding appropriate amount of normal saline and centrifuged at 3000*!r/*!min . The supernatant was collected for measurement of protein conentration and then mixed with Freund adjuvant. This antigen fluid was first injected into the plantae of the model group rats, and then into their plantae, dorsa, inguina and abdominal cavities (no Freund adjuvant for the last injection) again on the 10th, 17th, 24th and 31st day. When a certain titer of serum anti colonic antibody was reached, 2% formalin and antigen fluid (no Freund adjuvant) were administered separately by enema. The ulcerative colitis rat model was thus set up. The animals were randomly divided into four groups: model control group (MC, n =8), electro acupuncture group (EA, n =8), herbs partition moxibustion group (HPM 8), normal control group (NC, n =8). HPM: Moxa cones made of refined mugwort floss were placed on the medicinal pad (medicinal pad dispensing: Radix Aconiti praeparata, cortex Cinnamomi, etc ) for Qihai (RN 6) and Tianshu (ST 25, bilateral) and ignited. Two moxa cones were used for each acupoint once a day and 14 times in all. EA: Tianshu (bilateral) and Qihai were stimulated by the intermittent pulse with 2Hz frequency, 4mA intensity for 20 minutes once a day and 14 times in all. After treatment, rats of all four groups were killed simultaneously. The spleen was separated and the distal colon was dissected. Total tissue RNA was isolated by the guanidinium thiocyanate phenol chloroform extraction method. RT PCR technique was used to study the expression of IL 1β and IL 6 mRNA. RESULTS IL 1β and IL 6 mRNAs were not detected in the spleen and colonic mucosa of the NC rats, whereas they were significantly expressed in that of the MC rats. IL 1β and IL 6 mRNAs were markedly lower in the EA and HPM rats than that in MC rats. There was no significant difference between the levels of IL 1β and IL 6 mRNAs in the EA and HPM rats. The expressions of IL 1β and IL 6 mRNAs were nearly the same in the spleen and colon of all groups. CONCLUSION Acupuncture and moxibustion greatly inhibited the expression of IL 1β and IL 6 mRNA in the experimental ulcerative colitis rats.Wu HG Zhou LB Pan YY Huang C Chen HP Shi Z Hua XG 1999World Journal of Gastroenterology1999,5,6:45

6miR-200 family expression is downregulated upon neoplastic progression of Barrett's esophagus显示文摘AIM: To investigate miR-200 family expression in Barrett's epithelium, gastric and duodenal epithelia, and esophageal adenocarcinoma. METHODS: Real-time reverse transcriptase-polymerase chain reaction was used to measure miR-200, ZEB1 and ZEB2 expression. Ingenuity Pathway Analysis of miR-200 targets was used to predict biological outcomes. RESULTS: Barrett's epithelium expressed lower levels of miR-141 and miR-200c than did gastric and duodenal epithelia (P < 0.001). In silico analysis indicated roles for the miR-200 family in molecular pathways that distinguish Barrett's epithelium from gastric and duodenalepithelia, and which control apoptosis and proliferation. All miR-200 members were downregulated in adenocarcinoma (P < 0.02), and miR-200c expression was also downregulated in non-invasive epithelium adjacent to adenocarcinoma (P < 0.02). The expression of all miR-200 members was lower in Barrett's epithelium derived high-grade dysplastic cell lines than in a cell line derived from benign Barrett's epithelium. We observed signif icant inverse correlations between miR-200 family expression and ZEB1 and ZEB2 expression in Barrett's epithelium and esophageal adenocarcinoma (P < 0.05). CONCLUSION: miR-200 expression might contribute to the anti-apoptotic and proliferative phenotype of Barrett's epithelium and regulate key neoplastic processes in this epithelium.Cameron M Smith David I Watson Mary P Leong George C Mayne Michael Z Michael Bas PL Wijnhoven Damian J Hussey 2011World Journal of Gastroenterology2011,17,8:13
7MRI阴性药物难治性颞叶癫痫合并抑郁症患者的静息态功能磁共振研究显示文摘背景抑郁症在颞叶癫痫中发生率高达50%~60%,而30%的药物难治性颞叶癫痫患者可表现为头颅核磁共振(MRI)无明显异常,这部分患者相较于伴有海马硬化的药物难治性颞叶癫痫患者出现继发性全面强直阵挛发作的机率更高。因此,MRI阴性药物难治性颞叶癫痫合并抑郁症的患者,生活质量更差、自杀风险更高,更需要癫痫外科手术治疗。朱曦 陈蕾 罗程 Zhu X He Z Luo C 2018癫痫杂志2018,4,3:11

12Direct-fed microbes: A tool for improving the utilization of low quality roughages in ruminants显示文摘For many years, ruminant nutritionists and microbiologists have been interested in manipulating the microbial ecosystem of the rumen to improve production efficiency of different ruminant species. Removal and restriction of antibiotics subtherapeutic uses from ruminant diets has amplified interest in improving nutrient utilization and animal performance and search for more safe alternatives. Some bacterial and fungal microorganisms as a direct-fed microbial(DFM) can be the most suitable solutions. Microorganisms that are commonly used in DFM for ruminants may be classified mainly as lactic acid producing bacteria(LAB), lactic acid utilizing bacteria(LUB), or other microorganism's species like Lactobacillus, Bifidobacterium, Enterococcus, Streptococcus, Bacillus, Propionibacterium, Megasphaera elsdenii and Prevotellabryantii, in addition to some fungal species of yeast such as Saccharomyces and Aspergillus. A definitive mode of action for bacterial or fungal DFM has not been established; although a variety of mechanisms have been suggested. Bacterial DFM potentially moderate rumen conditions, and improve weight gain and feed efficiency. Fungal DFM may reduce harmful oxygen from the rumen, prevent excess lactate production, increase feed digestibility, and alter rumen fermentation patterns. DFM may also compete with and inhibit the growth of pathogens, immune system modulation, and modulate microbial balance in the gastrointestinal tract. Improved dry matter intake, milk yield, fat corrected milk yield and milk fat content were obtained with DFM administration. However, the response to DFM is not constant; depending on dosages, feeding times and frequencies, and strains of DFM. Nonetheless, recent studies have supported the positive effects of DFM on ruminant performance.Mona M Y Elghandour Abdelfattah Z M Salem Jose S Martínez Castaeda Luis M Camacho Ahmed E Kholif Juan C Vázquez Chagoyán 2015Journal of Integrative Agriculture2015,14,3:7

15Through-needle all-optical ultrasound imaging in vivo: a preclinical swine study显示文摘High-frequency ultrasound imaging can provide exquisite visualizations of tissue to guide minimally invasive procedures.Here,we demonstrate that an all-optical ultrasound transducer,through which light guided by optical fibers is used to generate and receive ultrasound,is suitable for real-time invasive medical imaging in vivo.Broad-bandwidth ultrasound generation was achieved through the photoacoustic excitation of a multiwalled carbon nanotube-polydimethylsiloxane composite coating on the distal end of a 300-μm multi-mode optical fiber by a pulsed laser.The interrogation of a high-finesse Fabry–Pérot cavity on a single-mode optical fiber by a wavelength-tunable continuous-wave laser was applied for ultrasound reception.This transducer was integrated within a custom inner transseptal needle(diameter 1.08 mm;length 78 cm)that included a metallic septum to acoustically isolate the two optical fibers.The use of this needle within the beating heart of a pig provided unprecedented realtime views(50 Hz scan rate)of cardiac tissue(depth:2.5 cm;axial resolution:64μm)and revealed the critical anatomical structures required to safely perform a transseptal crossing:the right and left atrial walls,the right atrial appendage,and the limbus fossae ovalis.This new paradigm will allow ultrasound imaging to be integrated into a broad range of minimally invasive devices in different clinical contexts.Malcolm C Finlay Charles A Mosse Richard J Colchester Sacha Noimark Edward Z Zhang Sebastien Ourselin Paul C Beard Richard J Schilling Ivan P Parkin Ioannis Papakonstantinou Adrien E Desjardins 2017Light(Science & Applications)2017,6,1:6

18笋芽顶端分生组织在竹秆横切面形态形成中的作用与机制研究显示文摘竹秆的横切面主要由表皮、皮层、维管组织、基本组织及髓腔(早期为髓组织)组成。这些组织均由笋芽茎顶端分生组织分化发育而来,且其在生长发育过程中促使了竹秆横切面形态(本文特指:竹秆横切面外轮廓形状、围度及壁-腔结构)的形成。然而,人们对于这一生长发育过程的生物学机制知之甚少。本研究利用解剖学、数学模拟等方法,对 20 种具不同秆径竹种的笋芽顶端分生组织进行了分析。研究结果发现,笋芽顶端分生组织指状形态的维持是竹子产生圆柱形竹秆的基础;在顶端分生组织细胞数目增加的同时,线性增加原体细胞数目应是竹子在演化过程中产生大径竹秆且保持规则壁-腔结构的方式。进一步通过研究一个竹壁增厚且壁-腔架构紊乱的稳定变异体———实肚竹( Phyllostachys nidularia f. farcta)发现,其笋芽顶端分生组织细胞数目减少且原体/原套细胞数比值降低使其产生了高比例的壁组分组织(指基本分生组织与肋状分生组织)与低比例的髓组织。上述 2 种组织的比例失衡,使得实肚竹笋芽在后续发育中壁组分组织随机挤入到了髓组织中,最终形成了实肚竹异常的竹秆横切面形态(竹壁多样化增厚且壁-腔结构紊乱)。此外,相对较小的顶端分生组织,使得实肚竹笋芽产生了较少的内源激素,如其生长素含量仅约为其原种篌竹的 67. 5%,各细胞分裂素含量也显著低于篌竹笋芽。转录组分析进一步发现,在实肚竹笋芽中与激素及代谢相关的功能基因呈显著下调表达。这些生理与分子变化最终导致了实肚竹竹秆矮化、秆径减小且生物量降低。本论文的研究结果为研究竹秆横切面发育提供了一个重要的视角,同时也为实肚竹厚壁茎秆的形成提出了一个合理的机制。Wang Y Sun X Ding Y Fei Z Jiao C Fan M Yao B Xin P Chu J Wei Q 王雨珺 魏强 2019世界竹藤通讯2019,17,3:5
