5Minimal invasive microscopic tooth preparation in esthetic restoration: a specialist consensus显示文摘By removing a part of the structure,the tooth preparation provides restorative space,bonding surface,and finish line for various restorations on abutment.Preparation technique plays critical role in achieving the optimal result of tooth preparation.With successful application of microscope in endodontics for>30 years,there is a full expectation of microscopic dentistry.However,as relatively little progress has been made in the application of microscopic dentistry in prosthodontics,the following assumptions have been proposed:Is it suitable to choose the tooth preparation technique under the naked eye in the microscopic vision?Is there a more accurate preparation technology intended for the microscope?To obtain long-term stable therapeutic effects,is it much easier to achieve maximum tooth preservation and retinal protection and maintain periodontal tissue and oral function health under microscopic vision?Whether the microscopic prosthodontics is a gimmick or a breakthrough in obtaining an ideal tooth preparation should be resolved in microscopic tooth preparation.This article attempts to illustrate the concept,core elements,and indications of microscopic minimally invasive tooth preparation,physiological basis of dental pulp,periodontium and functions involved in tool preparation,position ergonomics and visual basis for dentists,comparison of tooth preparation by naked eyes and a microscope,and comparison of different designs of microscopic minimally invasive tooth preparation techniques.Furthermore,a clinical protocol for microscopic minimally invasive tooth preparation based on target restorative space guide plate has been put forward and new insights on the quantity and shape of microscopic minimally invasive tooth preparation has been provided.Haiyang Yu Yuwei Zhao Junying Li Tian Luo Jing Gao Hongchen Liu Weicai Liu Feng Liu Ke Zhao Fei Liu Chufan Ma Juergen MSetz Shanshan Liang Lin Fan Shanshan Gao Zhuoli Zhu Jiefei Shen Jian Wang Zhimin Zhu Xuedong Zhou 2019International Journal of Oral Science2019,11,4:25
6Fast track clinical pathway implications in esophagogastrectomy显示文摘AIM:To investigate the feasibility of fast track clinical pathway for esophageal tumor resections. METHODS:One hundred and fourteen patients with esophageal carcinoma who underwent esophagogastrectomy from January 2006 to October 2007 in our department were studied.Fast track clinical pathway included analgesia control,fluid infusion volume control,early ambulation and enteral nutrition. Nasogastric tube was removed 3 d after operation and chest tube was removed 4 d after operation as a routine,and full liquid diet 5 d after operation. RESULTS:Among 114 patients(84 men and 30 women),26 patients underwent fast track surgery,including 17 patients over 65 years old and 9 under 65(P=0.014);18 patients who had preoperative complications could not bear fast track surgery(P< 0.001).No significant differences in tolerance of fast track surgery were attributed to differences in gender,differentiated degree or stage of tumor,pathological type of tumor,or operative incision.The median length of hospital stay was 7 d(5-28 d),4%patients were readmitted to hospital within 30 d of discharge.Three patients died and postoperative mortality was 2.6%. All 3 patients had no determinacy to fast track surgery approach.CONCLUSION:The majority of patients with esophageal carcinoma can tolerate fast track surgery. Patients younger than 65 or who have no preoperative diseases have the best results.Median length of hospital stay has been reduced to 7 d.Ke Jiang Lin Cheng Jian-Jun Wang Jin-Song Li Jun Nie 2009World Journal of Gastroenterology2009,15,4:24
7Late Mesozoic extensional tectonics of the Liaodong Peninsula massif:Response of crust to continental lithosphere destruction of the North China Craton显示文摘Unlike most Precambrian cratons that have thick sub-continental lithospheric roots,the Archean lithosphere beneath the North China Craton is thin (reduced from 200 km to about 80 km),and has been replaced by a geochemically juvenile lithospheric mantle.This is a unique regional geological event,which has attracted worldwide attention.In the North China Block,Late Mesozoic extensional tectonics is evident by low-angle detachment faults,syntectonic plutons bounded by ductile faults,metamorphic core complexes (MCC) and widespread Jurassic to Cretaceous half-grabens filled by continental terrigenous deposits and volcanic rocks.At a regional scale,these structures share the same NW-SE extensional direction,while maintaining their own individual kinematics.In other words,the MCC feature a top-to-the-NW sense of shear,and syntectonic plutons are typified by a top-to-the-SE shearing deformations.Geochronological results indicate that the extensional structures were formed between 130-120 Ma.These extensional events lead to magmatic rock emplacement,distributed at the footwall of the detachment faults.Two different exhumation stages can be identified based on regional structural and magmatic interpretation:a Jurassic slow or negligible exhumation and a Cretaceous fast one assisted by normal faulting.These two cooling stages correspond to distinct geodynamic processes that occurred during the Jurassic and Cretaceous.Extensional tectonics appear to have been insignificant before the Early Cretaceous,and the process may be demonstrated by partial melting of the crust.The second stage,dominated by an extensional regime,developed after ca 120 Ma,and is tentatively correlated with crustal extension caused by lithospheric removal of the North China Craton.LIN Wei WANG QingChen WANG Jun WANG Fei CHU Yang CHEN Ke 2011Science China Earth Sciences2011,54,6:24

9Intracoronary arterial retrograde thrombolysis with percutaneous coronary intervention: a novel use of thrombolytic to treat acute ST-segment elevation myocardial infarction显示文摘Background Clearance of coronary arterial thrombosis is necessary in patients with acute ST-segment elevation myocardial infarction (STEMI) undergoing urgent percutaneous coronary intervention (PCI). There is currently no highly-recommended method of thrombus removal during interventional procedures. We describe a new method for opening culprit vessels to treat STEMI: intracoronary arterial retrograde thrombolysis (ICART) with PCI. Methods & Results Eight patients underwent ICART. The guidewire was advanced to the distal coronary artery through the occlusion lesion. Then, we inserted a microcatheter into the distal end of the occluded coronary artery over the guidewire. Urokinase (5–10 wu) mixed with contrast agents was slowly injected into the occluded section of the coronary artery through the microcatheter. The intracoronary thrombus gradually dissolved in 3–17 min, and the effect of thrombolysis was visible in real time. Stents were then implanted according to the characteristics of the recanalized culprit lesion to achieve full revascularization. One patient experienced premature ventricular contraction during vascular revascularization, and no malignant arrhythmias were seen in any patient. No reflow or slow flow was not observed post PCI. Thrombolysis in myocardial infarction flow grade and myocardial blush grade post-primary PCI was 3 in all eight patients. No patients experienced bleeding or stroke. Conclusions ICART was accurate and effective for treating intracoronary thrombi in patients with STEMI in this preliminary study. ICART was an effective, feasible, and simple approach to the management of STEMI, and no intraprocedural complications occurred in any of the patients. ICART may be a breakthrough in the treatment of acute STEMI.Jin-Wen TIAN Mei ZHU Feng-Qi WANG Ke LI Chao-Fei ZHOU Bo LI Min WANG Jue-Lin DENG Bo JIANG Jing BAI Yi GUO Rong-Jie JIN Zhao ZHANG Ying LIN Ji-Hang WANG Shi-Hao ZHAO Ming-Zhi SHEN 2019Journal of Geriatric Cardiology2019,16,6:22
10A Review of Seasonal Climate Prediction Research in China显示文摘The ultimate goal of climate research is to produce climate predictions on various time scales. In China, efforts to predict the climate started in the 1930 s. Experimental operational climate forecasts have been performed since the late 1950 s,based on historical analog circulation patterns. However, due to the inherent complexity of climate variability, the forecasts produced at that time were fairly inaccurate. Only from the late 1980 s has seasonal climate prediction experienced substantial progress, when the Tropical Ocean and Global Atmosphere project of the World Climate Research program(WCRP) was launched. This paper, following a brief description of the history of seasonal climate prediction research, provides an overview of these studies in China. Processes and factors associated with the climate variability and predictability are discussed based on the literature published by Chinese scientists. These studies in China mirror aspects of the climate research effort made in other parts of the world over the past several decades, and are particularly associated with monsoon research in East Asia. As the climate warms, climate extremes, their frequency, and intensity are projected to change, with a large possibility that they will increase. Thus, seasonal climate prediction is even more important for China in order to effectively mitigate disasters produced by climate extremes, such as frequent floods, droughts, and the heavy frozen rain events of South China.WANG Huijun FAN Ke SUN Jianqi LI Shuanglin LIN Zhaohui ZHOU Guangqing CHEN Lijuan LANG Xianmei LI Fang ZHU Yali CHEN Hong ZHENG Fei 2015Advances in Atmospheric Sciences2015,32,2:20

18Triptolide Inhibits Expression of Inflammatory Cytokines and Proliferation of Fibroblast-like Synoviocytes Induced by IL-6/sIL-6R-Mediated JAK2/STAT3 Signaling Pathway显示文摘Triptolide,a component of the Chinese herb Tripterygium wilfordii Hook F,has been proved to be effective in the treatment of rheumatoid arthritis(RA).However,its underlying mechanisms on RA have not yet been well established.We observed the inhibitory effect of triptolide on the expression of inflammatory cytokines and proliferation of fibroblast-like synoviocytes(FLS)induced by the complex of interleukin-6(IL-6)and the soluble form of the IL-6 receptor(sIL-6R).Furthermore,to clarify the underlying mechanisms,we treated FLS with the Janus-activated kinase 2(JAK2)inhibitor/signal transducer and activator of transcription 3(STAT3)activation blocker AZD1480.In this study,immunohistochemical staining was used to identify vimentin(+)and CD68(−)in FLS.The FLS proliferation was measured by cell proliferation assay,and the cell cycles were analyzed by flow cytometry.Furthermore,ELISA was used to detect the expression of the inflammatory factors in culture solution.The expression levels of p-JAK2,JAK2,p-STAT3 and STAT3 were investigated through Western blotting analysis.The results showed that IL-6/sIL-6R significantly increased the cell proliferation and expression of inflammatory cytokines,including IL-6,interleukin-1β(IL-1β)and vascular endothelial growth factor(VEGF).Triptolide or AZD1480 inhibited the cell proliferation and inflammatory cytokine expression in IL-6/sIL-6R-stimulated FLS by suppressing JAK2/STAT3.The study suggested that the physiological effects of triptolide on RA were due to its contribution to the inhibition of the inflammatory cytokine expression and FLS proliferation by suppressing the JAK2/STAT3 signaling pathway.It may provide an innovative insight into the effect of triptolide in preventing RA pathogenesis.Jian-jing LIN Ke TAO Nan GAO Hui ZENG De-li WANG Jun YANG Jian WENG 2021Current Medical Science2021,41,1:13

20Downregulation of serum mi R-17 and mi R-106b levels in gastric cancer and benign gastric diseases显示文摘Altered micro RNA(mi RNA) associated with gastric cancer(GC) development and mi R-17 and mi R-106 b were differentially expressed in GC tissues. This study detected serum levels of mi R-17 and mi R-106 b expression in GC, benign gastric disease(BGD) and healthy controls to assess them as tumor markers for GC. Serum samples from 40 GC, 32 BGD(10 gastric ulcer, 14 gastric polyps, and 8 gastric ulcer with polyps) and 36 healthy individuals were subjected to quantitative reverse transcription polymerase chain reaction(q RT-PCR) analysis of mi R-17 and mi R-106 b expression. The data showed that the serum levels of mi R-17 and mi R-106 b were significantly reduced in healthy individuals and BGD patients compared to GC patients. There was a significant association of mi R-17 and mi R-106 b expression with age, but not with other clinicopathological features, such as gender, tumor differentiation, stage and lymphatic metastasis. Further analysis showed that, in discriminating GC patients from healthy controls, mi R-17 could yield a receiver-operating characteristic(ROC) area under the curve(AUC) of 0.879 with 80.6% sensitivity and 87.5% specificity and mi R-106 b could yield an AUC of 0.856 with 75.0% sensitivity and 92.5% specificity. The combined AUC of mi R-17 and mi R-106 b was 0.913 with 83.3% sensitivity and 87.5% specificity. Collectively, these data suggest that detection of serum mi R-17 and mi R-106 b levels should be further evaluated as novel non-invasive biomarkers in early GC detection and surveillance of disease progression.Qinghai Zeng Cuihong Jin Wenhang Chen Fang Xia Qi Wang Fan Fan Juan Du Yihang Guo Changwei Lin Kaiyan Yang Jingjing Li Xiaowei Peng Xiaorong Li Ke Cao 2014Chinese Journal of Cancer Research2014,26,6:12
