6Repeatability and Reproducibility of Quantitative Assessment of the Retinal Microvasculature Using Optical Coherence Tomography Angiography Based on Optical Microangiography显示文摘Objective The aim of this study was to determine the repeatability and reproducibility of optical coherence tomography angiography(OCTA) based on optical microangiography(OMAG) measurements of macular vessels in normal eyes. Methods In this prospective cohort study, 40 eyes of 40 healthy volunteers underwent repeated OCTA(Cirrus HD-OCT 5000 angiography system, Carl Zeiss Meditec, Inc.) scans on two separate visit days. On each visit day, the eyes were scanned three times. The following parameters were used to quantitatively describe the OCTA images of the superficial vascular network: vessel area density(VAD), vessel skeleton density(VSD), vessel diameter index(VDI), vessel perimeter index(VPI), vessel complexity index(VCI), flux, and foveal avascular zone(FAZ). Coefficient of variation(CV) and intraclass correlation coefficient(ICC) were calculated for evaluating intravisit and intervisit repeatability, as well as interobserver reproducibility. Results The measurements showed high repeatability [CVs ≤ 4.2%(intravisit) and ≤ 4.6%(intervisit)] and interobserver reproducibility(ICCs ≥ 0.923) for all parameters. Conclusion This study demonstrated good repeatability and reproducibility of OCTA based on OMAG for the measurement of superficial vessel parameters in normal eyes.ZHAO Qi YANG Wen Li WANG Xiao Na Ruikang K Wang YOU Qi Sheng CHU Zhong Di XIN Chen ZHANG Meng Yu LI Dong Jun WANG Zi Yang CHEN Wei LI Yi Feng CUI Rui SHEN Lin WEI Wen Bin 2018Biomedical and Environmental Sciences2018,31,6:8
7Malnutrition and Quality of Life in Chinese Cancer Patients: a Clinical Study of 23,994 Subjects显示文摘Background Malnutrition is common in patients with cancer,and can negatively impact their quality of life(QoL)and even survival.However,there is currently no large data available on the prevalence of malnutrition in Chinese cancer patients.This study evaluated the prevalence of malnutrition and the QoL of Chinese patients with locoregional,recurrent or metastatic cancer.Methods We conducted a nationwide observational,multi-center,hospital-based cross-sectional study within the Chinese Society of Nutritional Oncology(CSNO)Network.All of the patients were diagnosed with one of the following 18 different types of malignant tumors:lung cancer,gastric cancer,liver cancer,colorectal cancer,breast cancer,esophageal cancer,cervical cancer,endometrial cancer,nasopharyngeal carcinoma,malignant lymphoma,leukemia,pancreatic cancer,ovarian cancer,prostate cancer,bladder cancer,brain cancer,biliary tract malignant tumors or gastrointestinal stromal tumors.These patients were enrolled from 72 hospitals located in different regions of China.The patients’nutritional status was evaluated based on the body mass index(BMI),loss of bodyweight,laboratory measurements and patient generated-subjective global assessment(PG-SGA)scores.The cancer patients’physical status and QoL were assessed by the Karnofsky Performance Status(KPS)questionnaire and the European Organization for Research and Treatment of Cancer(EORTC)QLQ-C30 questionnaire,respectively.Results From December 2013 to April 2016,23,994 patients hospitalized for cancer treatment(such as surgery,chemotherapy or radiotherapy)were enrolled in the study.The patients included 12,494(52.9%)males and 11,124(47.1%)females.The mean age was 55.8±13.7 years.The proportions of patients in cancer stagesⅠ,Ⅱ,Ⅲ,Ⅳand uncertain were 11.5%,20.3%,27.5%,30.2%and 10.5%,respectively.Among the 23,994 inpatients,the proportions of patients who were underweight(BMI<18.5 kg/m2),normal(18.5 kg/m2Hong Xia Xu Chun Hua Song Zhen Ming Fu Chang Wang Zeng Qing Guo Yuan Lin Ying Ying Shi Wen Hu Yi Ba Su Yi Li Zeng Ning Li Kun Hua Wang Jing Wu Ying He Jia Jun Yang Cong Hua Xie Fu Xiang Zhou Xin Xia Song Gong Yan Chen Wen Jun Ma Su Xia Luo Zi Hua Chen Ming Hua Cong Hu Ma Chun Ling Zhou Wei Wang Qi Luo Yong Mei Shi Yu Mei Qi Hai Ping Jiang Wen Xian Guan Jun Qiang Chen Jia Xin Chen Yu Fang Lan Zhou Yong Dong Feng Rong Shao Tan Tao Li Jun Wen Ou Qing Chuan Zhao Jian Xiong Wu Min Weng Qing Hua Yao Jiu Wei Cui Wei Li Han Ping Shi the Investigation on Nutrition Status and Clinical Outcome of Common Cancers(INSCOC)Group 2021Journal of Nutritional Oncology2021,6,1:8
8Psychophysiological Effects of Bamboo Plants on Adults显示文摘The present study was conducted to clarify the psychophysiological relaxation effects of viewing bamboo on university students. Forty healthy Chinese participants enrolled in this study to clarify the psychophysiological relaxation effects of viewing bamboo. The effects of visual stimulation using a pot both with and without a bamboo were recorded by measuring the student's blood pressure, EEG and STAI. We observed that viewing bamboo plants resulted in significantly lower systolic(female, P < 0.001; male, P < 0.001; P < 0.05) and diastolic(female,P < 0.001; male, P < 0.001; P < 0.05) blood pressures, but no changes in the pulse rate(female, P = 0.09; male, P = 0.07; P > 0.05) were observed. The results of the EEG analysis indicated brainwave variation(all P < 0.05) and lower anxiety scores(P < 0.01) after 3 min of viewing bamboo compared with the control. These findings indicate that visual stimulation with bamboo plants induced psychophysiological relaxation effects on adults.Ahmad Hassan CHEN Qi Bing JIANG Tao LYU Bing Yang LI Nian LI Shu SHANGGUAN Zi Yue LI Yun Ting JUN Zhou Li LUO Qian CHEN Xin Yi WANG Yi Yan ZENG Cheng Cheng YANG Jun Muhammad Sohaib Tahir 2017Biomedical and Environmental Sciences2017,30,11:8

10Validity of the Chinese Version of the Patient-Generated Subjective Global Assessment (PG-SGA) in Lung Cancer Patients显示文摘The prevalence of malnutrition is high among oncology patients in China. Although the Patient- Generated Subjective Global Assessment (PG-SGA) is widely recognized as an important nutritional assessment tool, it has not been validated for Chinese cancer patients. The purpose of this study was to conduct an analysis of nutrition screening and assessment data to validate the Chinese version of the PG-SGA in Chinese patients with lung cancer. This was an observational, cross-sectional study of 2,000 consecutive adult patients with lung cancer treated at several tertiary hospitals in China. Anthropometric and patient descriptive data were collected. The PG-SGA generated a score for the nutritional risk and a global rating for the nutritional status. The internal consistency, external consistency, and construct validity were evaluated, and a known-groups comparison and principal component analyses were conducted to evaluate the reliability and validity of the PG-SGA. The known-groups comparison demonstrated the ability of the PG-SGA to differentiate lung cancer patients of different nutritional and body mass index (BMI) groups. A confirmatory factor analysis supported the original four-factor structure of the PG-SGA. In terms of the internal and external consistency, the PG-SGA demonstrated intra-class correlation coefficients (ICC) up to 0.987. Alternative form validity was also demonstrated between Box 4 of the PG-SGA and the Karnofsky Performance Status score, with excellent external consistency (r = 0.972, P < 0.001). The construct validity was supported, and selected questionnaire dimensions were evident in the principal component analysis. Significant Spearman correlations (P < 0.001) were demonstrated. The Chinese version of the PG-SGA demonstrated significant reliability and sufficient exploratory properties to support its validity. It seems to be a valid tool that can be used to access the nutritional status of Chinese lung cancer patients. The validity of the PG-SGA in Chinese cancer patients warrants further investigation in other cancer types.Zhen Ming Fu Hong Xia Xu Chun Hua Song Wei Li Zeng Qing Guo Yuan Lin Ying Ying Shi Wen Hu Yi Ba Su Yi Li Zeng Ning Li Kun Hua Wang Jing Wu Ying He Jia Jun Yang Cong Hua Xie Xin Xia Song Gong Yan Chen Wen Jun Ma Su Xia Luo Zi Hua Chen Ming Hua Cong Hu Ma Chun Ling Zhou Wei Wang Qi Luo Yong Mei Shi Yu Mei Qi Hai Ping Jiang Wen Xian Guan Jun Qiang Chen Jia Xin Chen Yu Fang Lan Zhou Yong Dong Feng Rong Shao Tan Tao Li Jun Wen Ou Qing Chuan Zhao Jian Xiong Wu Chang Wang Han Ping Shi The Investigation on Nutrition Status and Clinical Outcome of Common Cancers (INSCOC) Group 2016Journal of Nutritional Oncology2016,1,1:7
11Role of mammalian target of rapamycin signaling pathway in regulation of fatty acid oxidation in a preeclampsia-like mouse model treated with pravastatin显示文摘Background: Fatty acid oxidation (FAO) disorder is involved in the pathogenesis of some cases of preeclampsia (PE). Several show that mammalian target of rapamycin (mTOR) signaling pathway is related to FAO. Pravastatin (Pra) can promote FAO in Nio-nitro-L-arginine methyl ester (L-NAME) PE-like mouse model in our previous study. This study aimed to investigate the effect of mTOR signaling pathway in PE-like model treated with Pra. Methods: Pregnant mice were randomly injected with L-NAME as PE-like model group or saline as control group respectively, from gestational 7th to 18th day. Giving Pra (L-NAME + Pra, Control + Pra, n= 8) or normal saline (NS;L-NAME + NS, Control + NS, n = 8) from gestational 8th to 18th day, the mice were sacrificed on day 18 and their liver and placental tissues were collected. Then the activation of mTOR and its substrates in the liver and placenta were detected. And the association between mTOR activation and mice were randomly injected with L-NAME as PE-like model group or saline as control group respectively, from serum free fatty acid (FFA) levels and the expression of long-chain 3-hydroxyacyl-coenzyme A dehydrogenase (LCHAD) were evaluated using Pearson correlation test. Differences between groups were analyzed using independent t-test or one-way analysis of variance (ANOVA). Results: Both in the maternal liver and placenta, the activation of mTOR protein and its effect on substrates increased significantly in the L-NAME + NS group and decreased significantly in the L-NAME + Pra group. The p-mTOR/mTOR protein ratio decreased in the L-NAME + Pra group significantly than that in the L-NAME + NS group both in liver and placenta (liver: 0.74±0.08 vs. 0.85± 0.06, t=2.95, P<0.05;placenta: 0.63±0.06 vs.0.77±0.06, t=4.64, P<0.05). The activation of mTOR protein in the liver and placenta negatively correlated with the expression of LCHAD in the L-NAME + NS group (liver: r=—0.745, P<0.05;placenta: r=-0.833, P< 0.05) and that in the maternal liver negatively correlated with the expression of LCHAD (r=—0.733, P<0.05) and serum FFA levels positively with the (r=0.841, P< 0.05) in the L-NAME+ Pra group. Conclusion: The inhibition of mTOR signaling pathway might be involved in the regulation of FAO in mouse model treated with Pra.Jing Huai Zi Yang Yan-Hong Yi Guang-Jiao Wang 2019Chinese Medical Journal2019,,6:6
12Comparison of Histological, Microbiological, and Molecular Methods in Diagnosis of Patients with TBLN Having Different Anti-TB Treatment Background显示文摘Objective The influence of anti-tuberculosis(TB) treatment history on tuberculous lymphadenitis(TBLN) diagnosis is unclear. Therefore, this study aims to evaluate the diagnostic methods, including histology, microbiology, and molecular tests, used for TBLN. Methods In this study, suspected patients with TBLN and having different anti-TB treatment background were enrolled. All the samples were tested simultaneously by histology, Ziehl-Neelsen(ZN) staining, mycobacterial culture(culture), Xpert MTB/RIF(xpert), real-time PCR, and high-resolution melting curve PCR(HRM). Thereafter, the performance of these methods on samples with different anti-TB treatment background was assessed. Results In our study, 89 patients were prospectively included 82 patients with TBLN and 7 with other diseases. The overall sensitivities of Xpert, real-time PCR, histology, ZN staining, and culture were 86.6%, 69.5%, 58.5%, 43.9%, and 22.0%, respectively. The anti-TB treatment history revealed dramatic influences on the sensitivity of culture(P < 0.0001). In fact, the treatment that lasted over 3 months also influenced the sensitivity of Xpert(P < 0.05). However, the treatment history did not affect the performance of remaining tests(P > 0.05). For rifampicin drug susceptibility test(DST), the anti-TB treatment showed only significant influence on the success rate of culture DST(P = 0.001), but not on those of Xpert and HRM tests(P > 0.05). Conclusion Other tests as well as culture should be considered for patients with TBLN having retreatment history or over 1-month treatment to avoid false negative results.CHE Nan Ying HUANG Shao Jun MA Yan HAN Yi LIU Zi Chen ZHANG Chen MU Jing ZHAO Dan QU Yang ZHANG Hai Qing LIU Zhi Dong XU Shao Fa 2017Biomedical and Environmental Sciences2017,30,6:6
13Validity of the Chinese Version of the Patient-Generated Subjective Global Assessment (PG-SGA) in Gastric Cancer Patients显示文摘Purpose Malnutrition is severe among gastric cancer patients in China. While the Patient-Generated Subjective Global Assessment (PG-SGA) is a widely used nutritional assessment tool, the validation for Chinese patients with gastric cancer has not been performed yet. The aim of this research is to validate the Chinese version of the PGSGA in Chinese gastric cancer patients by conducting analyses of nutrition screening and assessment data. Methods Two thousand consecutive adult patients with gastric cancer were included in this observational, cross-sectional study in several tertiary hospitals in China. A survey was made among those patients, which included several questionnaires and some anthropometric parameters. We calculated the parameters to validate the use of PG-SGA categorizing the nutritional status of gastric cancer patients. Then we performed statistical analysis to evaluate the internal consistency, external consistency, and construct validity. Results This study verified the ability of the PG-SGA to differentiate gastric cancer patients into different nutritional groups. The confirmatory factor analysis verified the original four-factor structure of the PG-SGA. The internal and external consistency was measured by a concordance analysis which showed an intraclass correlation coefficients (ICC) of 0.987. The correlations of the Box 4 score with the Karnofsky performance status score demonstrated alternative form validity with good external consistency (Pearson, r = 0.643, P < 0.001). All three anthropometric dimensions of the PG-SGA were supported by principal component analysis. Spearman correlations (P < 0.001) were significant in the majority of tests. Conclusion The Chinese version of the PG-SGA is a valid tool to access the patients’ nutritional status for Chinese gastric patients.Zhen Ming Fu Hong Xia Xu Chun Hua Song Wei Li Zeng Qing Guo Yuan Lin Ying Ying Shi Wen Hu Yi Ba Su Yi Li Zeng Ning Li Kun Hua Wang Jing Wu Ying He Jia Jun Yang Cong Hua Xie Xin Xia Song Gong Yan Chen Wen Jun Ma Su Xia Luo Zi Hua Chen Ming Hua Cong Hu Ma Chun Ling Zhou Wei Wang Qi Luo Yong Mei Shi Yu Mei Qi Hai Ping Jiang Wen Xian Guan Jun Qiang Chen Jia Xin Chen Yu Fang Lan Zhou Yong Dong Feng Rong Shao Tan Tao Li Jun Wen Ou Qing Chuan Zhao Jian Xiong Wu Chang Wang Han Ping Shi The Investigation on Nutrition Status and Clinical Outcome of Common Cancers (INSCOC) Group 2018Journal of Nutritional Oncology2018,3,4:5
14Effects of electroacupuncture on astrocytes in the marginal zone of focal cerebral ischemia in rats显示文摘BACKGROUND:Astrocytes react sensitively to cerebral ischemia,causing reactive proliferation and activation,which may contribute to their effect in protecting or injuring neuronal regeneration. Whether acupuncture,as a treatment for cerebral ischemia,regulates the activated state of astrocytes has become a focus of recent investigations. OBJECTIVE:To observe the effects of electroacupuncture(EA) on ultrastructure changes and reactive proliferation of astrocytes in the marginal zone of focal cerebral ischemia in rats. DESIGN,TIME AND SETTING:Randomized,controlled animal study.This study was performed at the Experimental Animal Center of Guangzhou University of Traditional Chinese Medicine between December 2007 and July 2008. MATERIALS:A total of 90 male Wistar rats were randomly divided into sham operated,model and EA groups.Each group was subdivided into 1 hour,1,3,7,and 21 days post-cerebral ischemia groups,with six animals for each time point.Rabbit anti-rat glial fibrillary acidic protein (GFAP) and goat anti-rabbit IgG/tetramethylrhodamine isothiocyanate were provided by Beijing Biosynthesis Biotechnology.The G-6805 electric acupuncture apparatus was provided by Shanghai Huayi. METHODS:Heat-coagulation-induced occlusion of the middle cerebral artery was performed to establish a model of focal cerebral ischemia,in the model and EA groups.Middle cerebral arteries were exposed without occlusion in sham operated group.EA was applied immediately after surgery in the EA group,4/20 Hz,2.0-3.0 V,1-3 mA,to Baihui(GV 20) and Dazhui(GV 14),for 30 minutes.The treatment was performed once a day.The sham operated and model groups did not receive acupuncture. MAIN OUTCOME MEASURES:In the marginal zone of focal cerebral ischemia in rats at different time points after intervention,the ultrastructure changes of astrocytes were observed by using transmission electronic microscopy.GFAP expression in astrocytes was also measured by laser confocal scanning microscopy. RESULTS:Cell swelling and rapid proliferation of astrocytes were observed following cerebral ischemia.In comparison to the model group,the degree of swelling of astrocytes was significantly decreased in the EA group.Compared with the sham operated group at hour 1 post-surgery,there was no significant difference in the expression of average fluorescence intensity of GFAP between the EA and model groups(P>0.05),while the expression of GFAP in both the EA and model groups increased significantly at days 1,3,7 and 21 post-surgery(P<0.01).The expression of GFAP in EA group was also significantly lower than in the model group(P<0.01,P<0.05). CONCLUSION:Ultrastructural changes and reactive proliferation of astrocytes appear in the marginal zone of focal cerebral ischemia in rats.EA can relieve the degree of swelling of astrocytes and inhibit GFAP overexpression by activated astrocytes.These effects may be related to its ability to regulate the activated state of astrocytes.Yan Luo Nenggui Xu Wei Yi Yong Zi Yixu Du 2009Neural Regeneration Research2009,4,4:4
