BACKGROUND Stress urinary incontinence(SUI)is a common disease in *** emergence of the needle-free sling has led to a new clinical treatment for SUI in *** To explore the clinical value of the needleless sling without acupuncture in the treatment of SUI in *** From February 2017 to November 2018,according to the order of admission,44 patients(mid-suspension group)were treated by tension-free transobturator urethral suspension,and 44 patients(non-acupuncture group)were treated with a needleless non-acupuncture *** clinical effects of the two treatments were *** There was no significant difference between the two groups in the total clinical effectiveness rate(P=0.374),but intraoperative blood loss and visual analogue scale score at postoperative day 1 were significantly lower in the non-acupuncture suspension group than in the middle urethral suspension group(P=0.396).The incidence of complications in the needle-free sling group was significantly lower than that in the middle urethral suspension group(P=0.025).CONCLUSION The clinical effectiveness of acupuncture-free suspension in treating SUI in female patients is better than that of traditional tension-free transobturator mid-urethral suspension.

Prognostic and predictive blood biomarkers in gastric cancer and the potential application of circulating tumor cells

引用

World Journal of Gastroenterology 2018年第21期24卷 2236-2246页

作者： Ting-Ting li Hao liu jiang Yu guang-yao Shi li-Ying Zhao Guo-Xin li Department of General Surgery Nanfang HospitalSouthern Medical University Division of Cardiology Third Affiliated HospitalSun Yat-sen University

Gastric cancer(GC), with its high incidence and mortality rates, is a highly fatal cancer that is common in East Asia particularly in China. Its recurrence and metastasis are the main causes of its poor prognosis. Circulating tumor cells(CTCs) or other blood biomarkers that are released into the circulating blood stream by tumors are thought to play a crucial role in the recurrence and metastasis of gastric cancer. Therefore, the detection of CTCs and other blood biomarkers has an important clinical significance; in fact, they can help predict the prognosis, assess the staging, monitor the therapeutic effects and determine the drug susceptibility. Recent research has identified many blood biomarkers in GC, such as various serum proteins, autoantibodies against tumor associated antigens, and cell-free DNAs. The analysis of CTCs and circulating cell-free tumor DNA(ctDNA) in the peripheral blood of patients with gastric cancer is called as liquid biopsy. These blood biomarkers provide the disease status for individuals and have clinical meaning. In this review, we focus on the recent scientific advances regarding CTCs and other blood biomarkers, and discuss their origins and clinical meaning.

Scientific research and productive practice for earth history are inseparable from the accurate stratigraphic framework and time framework. Establishing the globally unified, precise and reliable chronostratigraphic series and geological time series is the major goal of the International Commission on Stratigraphy （ICS）. Under the leadership of the ICS, the countries around the world have carried out research on the Global Standard Stratotype-section and Points （GSSPs） for the boundaries of chronostratigraphic systems. In the current International Chronostratigraphic Chart （ICC）, 65 GSSPs have been erected in the Phanerozoic Eonothem, and one has yet been erected in the Precambrian Eonothem. Based on the progress of research on stratigraphy especially that from its subcommissions, the ICS is constantly revising the ICC, and will publish a new International Stratigraphic Guide in 2020. After continual efforts and broad international cooperation of Chinese stratigraphers, 10 GSSPs within the Phanerozoic Eonothem have been approved and ratified to erect in China by the ICS and IUGS. To establish the standards for strafigraphic division and correlation of China, with the support from the Ministry of Science and Technology, the National Natural Science Foundation of China and the China Geological Survey, Chinese stratigraphers have carried out research on the establishment of Stages in China. A total of 102 stages have been defined in the ＂Regional Chronostratigraphic Chart of China （geologic time）＂, in which 59 stages were studied in depth. In 2014, the ＂Stratigraphic Chart of China＂ was compiled, with the essential contents as follows： the correlation between international chronostratigraphy and regional chronostratigraphy of China （geologic time）, the distributive status of lithostratigraphy, the characteristics of geological ages, the biostratigraphic sequence, the magnetostratigraphy, the geological events and eustatic sea-level change during every geological stage.

Genetic Analysis and Molecular Mapping of a Rolling Leaf Mutation Gene in Rice

引用

Journal of Integrative Plant Biology 2007年第12期49卷 1746-1753页

作者： ji-Cai Yi Chu-Xiong Zhuang Xu-jie Wang You-Pei Cao yao-guang liu Man-Tong Mei Key Laboratory of Plant Functional Genomics and Biotechnology of guangdong Province College of Life Science South China Agricultural University Guangzhou 510642 China

A rice mutant with rolling leaf, namely γ-rl, was obtained from M2 progenies of a native indica rice stable strain Qinghuazhan （QHZ） from mutagenesis of dry seeds by γ-rays. Genetic analysis using the F2 population from a cross between this mutant and QHZ indicated the mutation was controlled by a single recessive gene. In order to map the locus for this mutation, another F2 population with 601 rolling leaf plants was constructed from a cross between y-rl and a japonica cultivar 02428. After primary mapping with SSR （simple sequence repeats） markers, the mutated locus was located at the short arm of chromosome 3, flanked by RM6829 and RM3126. A number of SSR, InDel （insertion/deletion） and SNP （single nucleotide polymorphism） markers within this region were further developed for fine mapping. Finally, two markers, SNP121679 and InDe1422395, were identified to be flanked to this locus with genetic distances of 0.08 cM and 0.17 cM respectively, and two SNP markers, SNP75346 and SNPl10263, were found to be co-segregated with this locus. These results suggested that this locus was distinguished from all loci for the rolling leaf mutation in rice reported so far, and thus renamed rl10（t）. By searching the rice genome database with closely linked markers using BLAST programs, an e-physical map covering rl10（t） locus spanning about a 50 kb region was constructed. Expression analysis of the genes predicted in this region showed that a gene encoding putative flavin-containing monooxygenase （FMO） was silenced in γ-rl, thus this is the most likely candidate responsible for the rolling leaf mutation.
