| 1 | Combined detection and subclass characteristics analysis of CTCs and CTECs by SE-iFISH in ovarian cancer显示文摘Objective:Hematogenous metastasis is essential for the progression of ovarian cancer(OC),and circulating tumor cells(CTCs)are part of the metastatic cascade.However,the detection rate of CTC is low due to the use of less sensitive detection methods.Therefore,this study aimed to detect CTCs and circulating tumorigenic endothelial cells(CTECs)in patients with OC using subtraction enrichment and immunostaining and fluorescence in situ hybridization(SE-iFISH).Methods:We enrolled a total of 56 subjects,including 20 OC patients and 36 ovarian benign tumor patients.CTCs and CTECs were captured by subtraction enrichment(SE)and counted and classified according to immunofluorescence staining of tumor markers(TMs)carbohydrate antigen 125(CA125)and human epididymis protein 4(HE4)combined with fluorescence in situ hybridization(iFISH)of chromosome 8(Chr8)aneuploidy.The diagnostic value and subtype characteristics of CTCs and CTECs were investigated.Results:The detection rate of CTCs by SE-iFISH was high.Compared with CA125 and HE4,Chr8 aneuploidy was the major identification feature of CTC.CTC counts in OC were statistically higher than those in benign groups.CTC and CTEC with≥pentaploidy were detected in both groups,illustrating the poor diagnostic value of CTC or CTEC.Distributions of triploid and tetraploid CTC subtypes were significantly different,and combined detection of triploid and tetraploid CTCs showed the best diagnostic value.In contrast,the distribution of CTECs in the OC and benign groups had no statistically significant difference.Small CTCs accounted for over 1/3 of the total CTC count.We also found that small CTCs and CTECs primarily comprised triploid cells,while large CTCs and CTECs mainly comprised pentaploidy and beyond.Conclusions:The application of SE-iFISH offered a more comprehensive understanding of heterogeneous CTCs and CTECs in OC.Analysis of subclass characteristics of the CTCs and CTECs according to Chr8 aneuploidy and cell size may broaden their potential clinical utility and deepen mechanistic studies in OC. | Hongyan Cheng Shang Wang Wenqing Luan Xue Ye Sha Dou Zhijian Tang Honglan Zhu Peter Ping Lin Yi Li Heng Cui Xiaohong Chang | 2021 | Chinese Journal of Cancer Research2021，33，2： | 3 |
| 2 | Effects of Multiple Cleaning and Disinfection Interventions on Infectious Diseases in Children: A Group Randomized Trial in China显示文摘Objective To assess the effectiveness of multiple cleaning and disinfection interventions in the homes and kindergartens, in reducing gastrointestinal and respiratory illnesses of children. Methods From October 2010 to September 2011, we performed a prospective, controlled study in China. 408 children under 5 years old were recruited and group randomized into intervention and control groups. Families and kindergartens in the intervention group were provided with antibacterial products for hand hygiene and surface cleaning or disinfection for one year. Each child's illness symptoms and sick leave were recorded every day. Results A total of 393 children completed the study, with similar baseline demographics in each of the 2 groups. Except for abdominal pain, the odds of symptoms(fever, cough and expectoration, runny nose and nasal congestion, diarrhea), illness(acute respiratory illness and gastrointestinal illness), and sick leave per person each month were significantly reduced by interventions. The rates of fever, diarrhea, acute respiratory illness, gastrointestinal illness and sick leave per person per year were significantly decreased as well. Conclusion Not only the acute respiratory and gastrointestinal illness but the sick leave rate in children were significantly reduced by multiple interventions. | BAN Hai Qun LI Tao SHEN Jin LI Jin PENG Pin Zhang YE Heng Ping ZHANG Liu Bo | 2015 | Biomedical and Environmental Sciences2015，28，11： | 2 |

| 4 | Preparation of the core-shell HMX@CS microparticles by biological excitation:Excellent hydrophobic-oleophilic properties and decreased impact sensitivity effectively显示文摘Inspired by the phenomenon of superhydrophobic plants and animals in nature,1,3,5,7-tetranitro-1,3,5,7-tetrazocane(HMX)@copper stearate(CS)core-shell composites with similar properties was prepared.A rough shell layer on the surface of the HMX was observed by scanning electron microscopy(SEM),and a series of in-depth characterization confirmed the successful generation of CS and the coreshell structure of the samples.Differential scanning calorimeter(DSC)proves that the crystal transition temperature(204℃)and high temperature decomposition exothermal temperature(284℃)of HMX@CS is almost unchanged compared with pure HMX,which means HMX and CS have good compatibility.Then,the H50 of the samples also increased continuously(16.6 cm→33.7 cm)when the CS shell content increased from 1%to 5%,indicating that the CS shell has a certain buffering performance,and CS will absorb some heat and melt under the stimulation of impact due to its low melting point,which improved impact sensitivity of HMX effectively further.Moreover,HMX@CS has excellent hydrophobic and oleophilic performance,shows excellent wettability with lipid binder,and samples with appropriate CS shell content can continue to combustion stably after covering water.This waterproof and low sensitivity coating provides a new way for the development of multifunctional energetic materials. | Yue-qi Li Heng Zhai Ping Ye Xing-quan Zhang Chang-ping Guo | 2022 | Defence Technology(防务技术)2022，18，5： | 0 |
