1Free triiodothyronine level indicates the degree of myocardial injury in patients with acute ST-elevation myocardial infarction显示文摘Wang Wen-yao Tang Yi-da Yang Min Cui Cheng Mu Mu Qian Jie Yang Yue-jin 2013Chinese Medical Journal2013,,20:21
2Ectopic osteogenesis and angiogenesis regulated by porous architecture of hydroxyapatite scaffolds with similar interconnecting structure in vivo显示文摘The macro-pore sizes of porous scaffold play a key role for regulating ectopic osteogenesis and angiogenesis but many researches ignored the influence of interconnection between macro-pores with different sizes.In order to accurately reveal the relationship between ectopic osteogenesis and macro-pore sizes in dorsal muscle and abdominal cavities of dogs,hydroxyapatite(HA)scaffolds with three different macro-pore sizes of 500–650,750–900 and 1100–1250 mm were prepared via sugar spheres-leaching process,which also had similar interconnecting structure determined by keeping the d/s ratio of interconnecting window diameter to macro-pore size constant.The permeability test showed that the seepage flow of fluid through the porous scaffolds increased with the increase of macro-pore sizes.The cell growth in three scaffolds was not affected by the macro-pore sizes.The in vivo ectopic implantation results indicated that the macro-pore sizes of HA scaffolds with the similar interconnecting structure have impact not only the speed of osteogenesis and angiogenesis but also the space distribution of newly formed bone.The scaffold with macro-pore sizes of 750–900 mm exhibited much faster angiogenesis and osteogenesis,and much more uniformly distribution of new bone than those with othermacro-pore sizes.This work illustrates the importance of a suitable macro-pore sizes in HA scaffolds with the similar interconnecting structure which provides the environment for ectopic osteogenesis and angiogenesis.Jinyu Li Wei Zhi Taotao Xu Feng Shi Ke Duan JianxinWang Yandong Mu Jie Weng 2016Regenerative Biomaterials2016,3,5:16

5Pediatric reference intervals in China(PRINCE):design and rationale for a large,multicenter collaborative cross-sectional study显示文摘There is a lack of accurate pediatric reference intervals(RIs) in China, with most commonly used RIs established without consideration of the effect of age and gender. The Pediatric Reference Intervals in China(PRINCE) project aims to establish and verify pediatric RIs for 31 common laboratory measurands.The project will be a large, multicenter cross-sectional study:14,490 healthy children and adolescents aged up to 19 years will be surveyed by 10 children's hospitals and one pediatric department of a university hospital. To evaluate the feasibility and efficiency of the study methods, 602 children were surveyed in the pilot phase of the PRINCE study in April 2017: it found that some measurands were distinctly age dependent and that there were differences between values for males and females. The results of the pilot study affirmed the necessity of the PRINCE project for Chinese pediatrics. The pilot also indicated potential difficulties in the full survey, e.g., difficulties in recruiting children aged under 3 years and insufficient collection of blood samples from infants. The operation of the PRINCE project has been modified based on the findings in the pilot study toward improving the validity of the PRINCE project and promoting its openness and transparency.Xin Ni Wenqi Song Xiaoxia Peng Ying Shen Yaguang Peng Qiliang Li Yan Wang Lixin Hu Yanying Cai Hong Shang Min Zhao Hong Jiang Yaoguo Huang Runqing Mu Wenxiang Chen Mingting Peng Chuanbao Zhang Jie Zeng Chenbin Li Hongling Yang Yongmei Jiang Jin Xu Guixia Li Hongbing Chen Yun Xiang Sancheng Cao Zhenxin Guo Dapeng Chen 2018Science Bulletin2018,63,24:12

7In Situ Corrosion Monitoring of Mild Steel in a Simulated Tidal Zone without Marine Fouling Attachment by Electrochemical Impedance Spectroscopy显示文摘The corrosion behaviors of the isolated short and vertical long scale Q235 B steel in a simulated tidal zone were studied by electrochemical impedance spectroscopy(EIS) monitoring and corrosion weight loss calculation in an experimental indoor simulating trough.The results show that the corrosion rate of the isolated short scale Q235 B steel in the tidal zone acquired by the EIS agrees with the corrosion weight loss result.The corrosion rates of the short scale steel are in the order of middle tidal zone > the central zone between the middle tidal zone and low tidal zone > high tidal zone > low tidal zone.The fastest corrosion rate in the middle tidal zone is attributed to the longest wet time in a tidal cycle.According to the comparison of corrosion weight loss between the vertical long scale and isolated short scale specimens,the corrosion rate of vertical long scale specimens of Q235 B steel is lower than that of the isolated short scale specimens in the tidal zone,but the result is contrary in the immersion zone.Xin Mu Jie Wei Junhua Dong Wei Ke 2014Journal of Materials Science & Technology2014,30,10:11
8A closed-loop process for recycling LiNi_xCo_yMn_((1-x-y))O_2 from mixed cathode materials of lithium-ion batteries显示文摘With the rapid development of consumer electronics and electric vehicles(EV), a large number of spent lithium-ion batteries(LIBs) have been generated worldwide. Thus, effective recycling technologies to recapture a significant amount of valuable metals contained in spent LIBs are highly desirable to prevent the environmental pollution and resource depletion. In this work, a novel recycling technology to regenerate a LiNi_(1/3)Co_(1/3)Mn_(1/3)O_2 cathode material from spent LIBs with different cathode chemistries has been developed. By dismantling, crushing,leaching and impurity removing, the LiNi_(1/3)Co_(1/3)Mn_(1/3)O_2(selected as an example of LiNi_xCo_yMn_(1-x-y)O_2) powder can be directly prepared from the purified leaching solution via co-precipitation followed by solid-state synthesis. For comparison purposes, a fresh-synthesized sample with the same composition has also been prepared using the commercial raw materials via the same method. X-ray diffraction(XRD), scanning electron microscopy(SEM) and electrochemical measurements have been carried out to characterize these samples. The electrochemical test result suggests that the re-synthesized sample delivers cycle performance and low rate capability which are comparable to those of the freshsynthesized sample. This novel recycling technique can be of great value to the regeneration of a pure and marketable LiNi_xCo_yMn_(1-x-y)O_2 cathode material with low secondary pollution.Rujuan Zheng Wenhui Wang Yunkun Dai Quanxin Ma Yuanlong Liu Deying Mu Ruhong Li Jie Rena Changsong Dai 2017Green Energy & Environment2017,2,1:11

11Updated experiences with minimally invasive Mc Keown esophagectomy for esophageal cancer显示文摘AIM: To update our experiences with minimally invasive Mc Keown esophagectomy for esophageal cancer.METHODS: we retrospectively reviewed the medical records of 445 consecutive patients who underwent minimally invasive Mc Keown esophagectomy between January 2009 and July 2015 at the Cancer Hospital of Chinese Academy of Medical Sciences and used 103 patients who underwent open Mc Keown esophagectomy in the same period as controls. Among 375 patients who underwent total minimally invasive Mc Keown esophagectomy, 180 in the early period were chosen for the study of learning curve of total minimally invasive Mc Keown esophagectomy. These 180 minimally invasive Mc Keown esophagectomies performed by five surgeons were divided into three groups according to time sequence as group 1(n = 60), group 2(n = 60) and group 3(n = 60).RESULTS: Patients who underwent total minimally invasive Mc Keown esophagectomy had significantly less intraoperative blood loss than patients who underwent hybrid minimally invasive Mc Keown esophagectomy or open Mc Keown esophagectomy(100 ml vs 300 ml vs 200 ml, P = 0.001). However, there were no significant differences in operation time, number of harvested lymph nodes, or postoperative morbidity includingincidence of pulmonary complication and anastomotic leak between total minimally invasive Mc Keown esophagectomy, hybrid minimally invasive Mc Keown esophagectomy and open Mc Keown esophagectomy groups. There were no significant differences in 5-year survival between these three groups(60.5% vs 47.9% vs 35.6%, P = 0.735). Patients in group 1 had significantly longer duration of operation than those in groups 2 and 3. There were no significant differences in intraoperative blood loss, number of harvested lymph nodes, or postoperative morbidity including incidence of pulmonary complication and anastomotic leak between groups 1, 2 and 3.CONCLUSION: Total minimally invasive Mc Keown esophagectomy was associated with reduced intraoperative blood loss and comparable short term and long term survival compared with hybrid minimally invasive Mc Keown esophagectomy or open Mckeown esophagectomy. At least 12 cases are needed to master total minimally invasive Mc Keown esophagectomy in a high volume center.Ju-wei Mu Shu-geng gao Qi Xue You-Sheng Mao Da-li wang Jun Zhao Yu-Shun gao Jin-feng Huang Jie He 2015World Journal of Gastroenterology2015,21,45:10
12Three new alkaloids isolated from the stem tuber of Pinellia pedatisecta显示文摘The present study was designed to determine the chemical constituents of the stem tuber of Pinellia pedatisecta. The chemical constituents were isolated and purified by various chromatographic techniques, and their structures were elucidated on the basis of physicochemical properties and spectral data. Three new alkaloids(compounds 1, 2, and 3) were obtained and identified as 9-((5-methoxypyridin-2-yl)methyl)-9 H-purin-6-amine(1), 4-(2-(2, 5-dioxopyrrolidin-1-yl)ethyl)phenyl acetate(2), and N-(9-((5-methoxypyridin-2-yl)methyl)-9 H-purin-6-yl)acetamide(3). These compounds were evaluated for their cytotoxicity against human cervical cancer He La cells. Compounds 1 and 3 significantly inhibited the proliferation of He La cells with IC_(50) values being 3.02 ± 0.54 and 7.16 ± 0.62 μmol·L^(-1), respectively.DU Jing DING Jie MU Zhen-Qiang GUAN Shu-Hong CHENG Chun-Ru LIU Xuan GUO De-An 2018Chinese Journal of Natural Medicines2018,16,2:10
13Sini powder ameliorates the inflammatory response in rats with stress-induced non-alcoholic fatty liver disease by inhibiting the nuclear factor kappa-B/pyrin domain-containing protein 3 pathway显示文摘OBJECTIVE: To evaluate the effectiveness of Sini powder for the treatment of non-alcoholic fatty liver disease(NAFLD) in rats and the molecular mechanisms involved.METHODS: A rat model of stress-induced NAFLD was established by a combination of long-term tethering and feeding of a high-fat, high-calorie diet. These rats were then intragastrically administered with either simvastatin, Sini powder, or vehicle for 1 week. The body mass and field test scores for each group were recorded weekly. Serum aspartate aminotransferase and alanine aminotransferase activities, and triglyceride, total cholesterol,and free fatty acid concentrations were measured.Liver tissue histopathology was examined on hematoxylin and eosin-stained paraffin sections and oil red O-stained frozen sections. The hepatic m RNA expression of nuclear factor kappa-B(NF-κB),NOD-, LRR-, and pyrin domain-containing protein 3(NLRP3), apoptosis-associated speck-like protein containing CARD(ASC), and caspase-1 were measured by reverse transcription-polymerase chain reaction(RT-PCR). The hepatic protein concentrations of NF-κB and NLRP3, ASC, caspase-1, interleukin-1β(IL-1β), interleukin-6(IL-6), and the serum concentrations of IL-1β and IL-6 were measured by enzyme-linked immunosorbent assay.RESULTS: Compared with the Blank group, rats in the Compound model group showed significant pathologic manifestations of NAFLD, and the expression of NF-κB, NLRP3, ASC, caspase-1, IL-1βand IL-6 were significantly higher(all P < 0.01). Both simvastatin and Sini powder significantly ameliorated the NAFLD pathology and the abnormal expression of NF-κB, NLRP3, ASC, caspase-1, IL-1β, and IL-6(all P < 0.01).CONCLUSION: Sini powder inhibits the inflamma-tory response in rats with NAFLD, which is mediated by NF-κB/NLRP3, IL-1β, and IL-6, reduces the effects of psychological stress, and improves lipid metabolism. Therefore, Sini powder may be effective for the treatment of stress-related NAFLD through multiple mechanisms.Mu Jie Cheng Fafeng Wang Qingguo Wang Xueqian Zhu Wenxiang Ma Chongyang Yin Xiangjun Ren Beida Lian Yajun Du Xin Zhang Haixia Liu Shuling Zhang Shuang 2020Journal of Traditional Chinese Medicine2020,40,2:9
14Application of video-assisted thoracic surgery in the standard operation for thoracic tumors显示文摘Objective: To evaluate the short-term outcomes of video-assisted thoracic surgery (VATS) for thoracic tumors. Methods: The data of 1,790 consecutive patients were retrospectively reviewed. These patients underwent VATS pulmonary resections, VATS esophagectomies, and VATS resections of mediastinal tumors or biopsies at the Cancer Institute & Hospital, Chinese Academy of Medical Sciences between January 2009 and January 2012. Results: There were 33 patients converted to open thoracotomy (OT, 1.84%). The overall morbidity and mortality rate was 2.79% (50/1790) and 0.28% (5/1790), respectively. The overall hospitalization and chest tube duration were shorter in the VATS lobectomy group (n=949) than in the open thoracotomy (OT) lobectomy group (n=753). There were no significant differences in morbidity rate, mortality rate and operation time between the two groups. In the esophageal cancer patients, no significant difference was found in the number of nodal dissection, chest tube duration, morbidity rate, mortality rate, and hospital length of stay between the VATS esophagectomy group (n=81) and open esophagectomy group (n=81). However, the operation time was longer in the VATS esophagectomy group. In the thymoma patients, there was no significant difference in the chest tube duration, morbidity rate, mortality rate, and hospital length of stay between the VATS thymectomy group (n=41) and open thymectomy group (n=41). However, the operation time was longer in the VATS group. The median tumor size in the VATS thymectomy group was comparable with that in the OT group. Conclusions: In early-stage (I/II) non-small cell lung cancer patients who underwent lobectomies, VATS is comparable with the OT approach with similar short-term outcomes. In patients with resectable esophageal cancer, VATS esophagectomy is comparable with OT esophagectomy with similar morbidity and mortality. VATS thymectomy for Masaoka stage I and II thymoma is feasible and safe, and tumor size is not contraindicated. Longer follow-ups are needed to determine the oncologic equivalency of VATS lobectomy, esophagectomy, and thymectomy for thymoma vs. OT.Ju-Wei Mu Gui-Yu Chen Ke-Lin Sun Da-Wei Wang Bai-Hua Zhang Ning Li Fang Lv You-Sheng Mao Qi Xue Shu-Geng Gao Jun Zhao Da-Li Wang Zhi-Shan Li Wen-Dong Lei Yu-Shun Gao Liangze Zhang Jin-Feng Huang Kang Shao Kai Su Kun Yang Liang Zhao Fei-Yue Feng Yong-Gang Wang Jian Li Jie He 2013Cancer Biology & Medicine2013,10,1:8
15Integrated metabolomic profiling for analysis of antilipidemic effects of Polygonatum kingianum extract on dyslipidemia in rats显示文摘AIM To identify the effects and mechanism of action of Polygonatum kingianum(P. kingianum) on dyslipidemia in rats using an integrated untargeted metabolomic method.METHODS A rat model of dyslipidemia was induced with a high-fat diet(HFD) and rats were given P. kingianum [4 g/(kg·d)] intragastrically for 14 wk. Changes in serum and hepatic lipid parameters were evaluated. Metabolites in serum, urine and liver samples were profiled using ultra-highperformance liquid chromatography/mass spectrometry followed by multivariate statistical analysis to identify potential biomarkers and metabolic pathways.RESULTS P. kingianum significantly inhibited the HFD-induced increase in total cholesterol and triglyceride in the liver and serum. P. kingianum also significantly regulated metabolites in the analyzed samples toward normal status. Nineteen, twenty-four and thirty-eight potential biomarkers were identified in serum, urine and liver samples, respectively. These biomarkers involved biosynthesis of phenylalanine, tyrosine, tryptophan, valine, leucine and isoleucine, along with metabolism of tryptophan, tyrosine, phenylalanine, starch, sucrose, glycerophospholipid, arachidonic acid, linoleic acid, nicotinate, nicotinamide and sphingolipid.CONCLUSION P. kingianum alleviates HFD-induced dyslipidemia by regulating many endogenous metabolites in serum, urine and liver samples. Collectively, our findings suggest that P. kingianum may be a promising lipid regulator to treat dyslipidemia and associated diseases.Xing-Xin Yang Jia-Di Wei Jian-Kang Mu Xin Liu Jin-Cai Dong Lin-Xi Zeng Wen Gu Jing-Ping Li Jie Yu 2018World Journal of Gastroenterology2018,24,48:8
16Toripalimab plus chemotherapy as second-line treatment in previously EGFR-TKI treated patients with EGFR-mutant-advanced NSCLC:a multicenter phase-II trial显示文摘This multicenter phase-II trial aimed to investigate the efficacy,safety,and predictive biomarkers of toripalimab plus chemotherapy as second-line treatment in patients with EGFR-mutant-advanced NSCLC.Patients who failed from first-line EGFR-TKIs and did not harbor T790M mutation were enrolled.Toripalimab plus carboplatin and pemetrexed were administrated every three weeks for up to six cycles,followed by the maintenance of toripalimab and pemetrexed.The primary endpoint was objective-response rate(ORR).Integrated biomarker analysis of PD-L1 expression,tumor mutational burden(TMB),CD8+tumor-infiltrating lymphocyte(TIL)density,whole-exome,and transcriptome sequencing on tumor biopsies were also conducted.Forty patients were enrolled with an overall ORR of 50.0%and disease-control rate(DCR)of 87.5%.The median progression free survival(PFS)and overall survival were 7.0 and 23.5 months,respectively.The most common treatment-related adverse effects were leukopenia,neutropenia,anemia,ALT/AST elevation,and nausea.Biomarker analysis showed that none of PD-L1 expression,TMB level,and CD8+TIL density could serve as a predictive biomarker.Integrated analysis of whole-exome and transcriptome sequencing data revealed that patients with DSPP mutation had a decreased M2 macrophage infiltration and associated with longer PFS than those of wild type.Toripalimab plus chemotherapy showed a promising anti-tumor activity with acceptable safety profiles as the second-line setting in patients with EGFR-mutant NSCLC.DSPP mutation might serve as a potential biomarker for this combination.A phase-III trial to compare toripalimab versus placebo in combination with chemotherapy in this setting is ongoing(NCT03924050).Tao Jiang Pingyang Wang Jie Zhang Yanqiu Zhao Jianying Zhou Yun Fan Yongqian Shu Xiaoqing Liu Helong Zhang Jianxing He Guanghui Gao Xiaoqian Mu Zhang Bao Yanjun Xu Renhua Guo Hong Wang Lin Deng Ningqiang Ma Yalei Zhang Hui Feng Sheng Yao Jiarui Wu Luonan Chen Caicun Zhou Shengxiang Ren 2021Signal Transduction and Targeted Therapy2021,6,11:8
17Reduning injection for fever, rash, and ulcers in children with mild hand, foot, and mouth disease: a randomized controlled clinical study显示文摘OBJECTIVE: To assess the efficacy and safety of Reduning injection for fever, rash, and ulcers in children with mild hand, foot, and mouth disease(HFMD). METHODS: A stratified-block randomized, double-blind, parallel-controlled, and multicenter clinical trial was conducted with 360 patients in five hospitals across China: Quanzhou Children's Hospital, Shijiazhuang No. 5 Hospital, Shanghai Public Health Centre, Hunan Provincial Children's Hospital, and Kaifeng Children's Hospital. Patients were randomized into three groups with 120 in each. Group A was treated with Western Medicine, group B with Reduning injection, a Chinese herbal medicine, and group C with both Reduning injection and Western Medicine. Results were compared for treatment efficacy and safety on HFMD. The clinical outcomes were observed as follows: fever and onset time of antifebrile effect(time to bring the body temperature down ≥0.5℃ after medication); cumulative time for fever recovery(body temperature recovering to normal and lasting more than 24 h without medication); cumulative time for rash disappearance(without new rashes or ulcers appearing and the original ones fading away); and cumulative time for mouth ulcer disappearance. RESULTS: For the onset time of the antifebrile effect, there was no statistical difference between groups A and B(P>0.05) and groups B and C(P> 0.05). However, there was a statistical difference between groups A and C(P<0.05), and the effect in group C was the best. For the cumulative time for rash disappearance, there was no statistical difference between groups A and B(P>0.05). There were statistical differences between groups A and C, and groups B and C(P<0.05), and the effect in group C was the best. For the cumulative time for mouth ulcers disappearance, there were no statistical differences among the three groups(P>0.05). CONCLUSION: Reduning injection with Western Medicine for symptomatic treatment is most effective for mild HFMD. No adverse reactions were observed.Guoliang Zhang Jie Zhao Liyun He Shiyan Yan Ziqiang Zhuo Haojie Zheng Yongping Mu Shuangjie Li Xi Zhang Jihan Huang Xiuhui Li Jianping Liu Hehe Wan Chaoyu Wei Wei Xiao 2013Journal of Traditional Chinese Medicine2013,33,6:7

19The Lifespan-Promoting Effect of Otophylloside B in Caenorhabditis elegans显示文摘Aging is the major risk factor for many human diseases and degeneration.Thus,clinically effective medicine could delay the process of aging and aging-related diseases are desperately wanted.In traditional Chinese medicine(TCM),some were claimed to slow down aging.Qingyangshen(Cynanchum otophyllum schneid)is such a TCM.Here,we assayed the longevity effect of compound Otophylloside B(Ot B),a C-21 steroidal glycoside isolated from Qingyangshen,in Caenorhabditis elegans,which is a popular model for aging research.Our results showed that Ot B could modestly extend the lifespan of C.elegans,delay the age-related decline of body movement and improve the stress resistance.Further investigating the molecular mechanism of lifespan extension effect revealed that Ot B could activate the FOXO transcription factor DAF-16.Ot B could not further extend the lifespan of long-lived mutant of insulin/IGF-1-like receptor(daf-2).In addition,Ot B also requires SIR-2.1 and CLK-1 which is an enzyme in ubiquinone synthesis,for lifespan extension.Jie Yang Qin-Li Wan Quan-Zhang Mu Chun-Feng Wu Ai-Jun Ding Zhong-Lin Yang Ming-Hua Qiu Huai-Rong Luo 2015Natural Products and Bioprospecting2015,5,4:6
20Long.term outcomes of 307 patients after complete thymoma resection显示文摘Background: Thymoma is an uncommon tumor without a widely accepted standard care to date. We aimed to investigate the clinicopathologic variables of patients with thymoma and identify possible predictors of survival and recurrence after initial resection.Methods: We retrospectively selected 307 patients with thymoma who underwent complete resection at the Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College(Beijing, China) between January 2003 and December 2014. The associations of patients' clinical characteristics with prognosis were estimated using Cox regression and Kaplan–Meier survival analyses.Results: During follow?up(median, 86 months; range, 24–160 months), the 5? and 10?year disease?free survival(DFS) rates were 84.0% and 73.0%, respectively, and the 5? and 10?year overall survival(OS) rates were 91.0% and 74.0%, respectively. Masaoka stage(P < 0.001), World Health Organization(WHO) histological classification(P < 0.001), and postoperative radiotherapy after initial resection(P = 0.006) were associated with recurrence(52/307, 16.9%). Multivariate analysis revealed that, after initial resection, WHO histological classification and Masaoka stage were independent predictors of DFS and OS. The pleura(25/52, 48.0%) were the most common site of recurrence, and locoregional recurrence(41/52, 79.0%) was the most common recurrence pattern. The recurrence pattern was an independent predictor of post?recurrence survival. Patients with recurrent thymoma who underwent repeated resec?tion had increased post?recurrence survival rates compared with those who underwent therapies other than surgery(P = 0.017).Conclusions: Masaoka stage and WHO histological classification were independent prognostic factors of thymoma after initial complete resection. The recurrence pattern was an independent predictor of post?recurrence survival. Locoregional recurrence and repeated resection of the recurrent tumor were associated with favorable prognosis.Zu-Yang Yuan Shu-Geng Gao Ju-Wei Mu Qi Xue You-Sheng Mao Da-Li Wang Jun Zhao Yu-Shun Gao Jin-Feng Huang Jie He 2017Chinese Journal of Cancer2017,36,10:6
