Background: Traditional Chinese Medicine (TCM), integrating patient preferences into decision-making process, has been widely used in the multimodality therapy of lung cancer. This study aimed to estimate patient preferences for treatment and shared decision-making (SDM) modes concerning inpatient TCM treatment of lung cancer in Shanghai in order to provide a basis for clinical decision-making process on TCM therapy for lung cancer. Methods: This study was conducted among patients (n = 347) from nine tertiary hospitals in Shanghai by discrete-choice experiment (DCE) survey and Shared Decision-Making Questionnaire-patient version (SDM-Q-9) survey. The DCE was developed with the inclusion of the most relevant attributes at appropriate levels for the TCM treatment of lung cancer. The empirical data analyses of patients were performed using mixed logit models. Additionally, subgroup analysis was conducted. Results: In total, 347 respondents completed the questionnaire. All attributes’ coefficients were statistically significant for patients’ preferences. Patients showed strong preferences for increasing disease control rate, relieving nausea and vomiting, reducing the risk of side effects, and were concerned about monthly out-of-pocket costs. Subgroup analysis indicated that patients with a lower SDM-Q-9 score and those who were satisfied with medical services emphasized more importance of higher disease control rate. Furthermore, most of the patients (90.20%) self-reported a high willingness to use SDM during the decision-making process. Conclusion: In Shanghai, patients mainly preferred SDM and considered disease control rate as the most essential attribute in the TCM treatment of lung cancer. The study findings could underscore the importance of considering patients’ preferences and promote SDM.

Li-Jun Zuo,Shu-Yang Yu,Fang Wang,Yanghui Xia,Ying-Shan Piao,Yang Du,Teng-Hong Lian,Rui-Dan Wang,Qiu-Jin Yu,Ya-Jie Wang,Xiao-Min Wang,Piu Chan,Sheng-Di Chen,Yongjun Wang,Wei Zhang 대한신경과학회 2016 Journal of Clinical Neurology Vol.12 No.2

Background and Purpose The aim of this study was to identify the clinical characteristics and potential mechanisms relevant to pathological proteins in Parkinson’s disease (PD) patients who experience fatigue. Methods PD patients (n=102) were evaluated using a fatigue severity scale and scales for motor and nonmotor symptoms. The levels of three pathological proteins—α-synuclein oligomer, β-amyloid (Aβ)1-42, and tau—were measured in 102 cerebrospinal fluid (CSF) samples from these PD patients. Linear regression analyses were performed between fatigue score and the CSF levels of the above-listed pathological proteins in PD patients. Results The frequency of fatigue in the PD patients was 62.75%. The fatigue group had worse motor symptoms and anxiety, depression, and autonomic dysfunction. The CSF level of α-synuclein oligomer was higher and that of Aβ1-42 was lower in the fatigue group than in the non-fatigue group. In multiple linear regression analyses, fatigue severity was significantly and positively correlated with the α-synuclein oligomer level in the CSF of PD patients, after adjusting for confounders. Conclusions PD patients experience a high frequency of fatigue. PD patients with fatigue have worse motor and part nonmotor symptoms. Fatigue in PD patients is associated with an increased α-synuclein oligomer level in the CSF

Wei Yuan,Qing-feng Wang,Wen-han Pei,Si-yu Li,Tian-min Wang,Hui-peng Song,Dan Teng,Ting-guo Kang,Hui Zhang 고려인삼학회 2024 Journal of Ginseng Research Vol.48 No.1

Background: Ginseng (Panax ginseng Mayer) is an important natural medicine. However, a long culture period andchallenging quality control requirements limit its further use. Although artificial cultivation can yield a sustainablemedicinal supply, research on the association between the transplantation and chaining of metabolicnetworks, especially the regulation of ginsenoside biosynthetic pathways, is limited. Methods: Herein, we performed Liquid chromatography tandem mass spectrometry based metabolomic measurementsto evaluate ginsenoside accumulation and categorise differentially abundant metabolites (DAMs). Transcriptome measurements using an Illumina Platform were then conducted to probe the landscape of geneticalterations in ginseng at various ages in transplantation mode. Using pathway data and crosstalk DAMs obtainedby MapMan, we constructed a metabolic profile of transplantation Ginseng. Results: Accumulation of active ingredients was not obvious during the first 4 years (in the field), but followingtransplantation, the ginsenoside content increased significantly from 6 8 years (in the wild). Glycerolipidmetabolism and Glycerophospholipid metabolism were the most significant metabolic pathways, as Lipids andlipid-like molecule affected the yield of ginsenosides. Starch and sucrose were the most active metabolic pathwaysduring transplantation Ginseng growth. Conclusion: This study expands our understanding of metabolic network features and the accumulation of specificcompounds during different growth stages of this perennial herbaceous plant when growing in transplantationmode. The findings provide a basis for selecting the optimal transplanting time.

Wei-Ning Yang,Zhi-Hong Ai,Juan Wang,Yan-Li Xu,Yincheng Teng 대한부인종양학회 2014 Journal of Gynecologic Oncology Vol.25 No.1

Objective: The objective of this study was to evaluate the effect of overexpression of epidermal growth factor receptor (EGFR) on the expression of epithelial cell markers (E-cadherin and α-catenin) and mesenchymal cell markers (N-cadherin and vimentin) in endometrial carcinoma. Methods: The expression of all 4 markers was evaluated in EGFR overexpressing Ishikawa cells, control Ishikawa cells, and KLE cells using reverse transcription polymerase chain reaction (RT-PCR) and Western blotting. The expression of these 4 markers was also determined in cancerous tissues of patients with endometrial carcinoma using immunohistochemical staining. Results: Ishikawa cells transfected with EGFR showed decreased expression of E-cadherin and α-catenin and increased expression of N-cadherin and vimentin compared with control Ishikawa cells (p<0.01 for all). The expression of N-cadherin and vimentin was higher and the expression of E-cadherin and α-catenin was lower in stage II-III than stage I and in grade II-III than grade I endometrial carcinoma tissue (p<0.01 for all). Conclusion: Decreased expression of epithelial markers (E-cadherin and α-catenin) and increased expression of mesenchymal markers (N-cadherin and vimentin) were observed in human endometrial carcinoma tissue. These findings correlate with high EGFR expression in cultured endometrial carcinoma cells.

Liver metastasis is a major cause of death in gastric cancer patients, but the underlying mechanisms are poorly understood. Through a combination of in vivo screening and transcriptome profiling followed by quantitative RT-PCR and tissue array analyses, we found that mitogen-activated protein kinase 4 (MAPK4) downregulation in gastric cancer tissues from patients is significantly associated with liver metastasis and poor prognosis. The knockdown of MAPK4 in gastric cancer cells promotes liver metastasis in orthotopic mouse models. MAPK4 depletion in gastric cancer cells induces the secretion of macrophage migration inhibitory factor (MIF) to polarize tumor-associated macrophages (TAMs) in orthotopic xenograft tumors. Moreover, TAMs activate epithelial–mesenchymal transition of gastric cancer cells to suppress MAPK4 expression, which further increases MIF secretion to polarize TAMs. Taken together, our results suggest a previously undescribed positive feedback loop between cancer cells and macrophages mediated by MAPK4 silencing that facilitates gastric cancer liver metastasis.

Li Jun Zhang,Wei Quan,Bei Bei Wang,Bing Ling Shen,Teng Teng Zhang,Yi Kang 한국미생물학회 2011 The journal of microbiology Vol.49 No.5

This study investigated the inhibitory effects of berberine on Chlamydophila (Chlamydia) pneumoniae infection-induced HEp-2 cell invasion and explored the possible mechanisms involved in this process. C. pneumoniae infection resulted in a significant increase in HEp-2 cell invasion when compared with the control cells (P<0.01) in a Matrigel invasion assay. This enhanced cell invasion was strongly suppressed by berberine (50 μM) (P<0.01). In a cell adhesion assay, the infection-induced HEp-2 cell adhesion to Matrigel was also significantly inhibited by berberine (P<0.01). C. pneumoniae infection was found to promote HEp-2 cell migration remarkably (P<0.01), which was markedly suppressed by berberine (P<0.01) in the cell migration assays. There were no statistically significant differences in the expression of matrix metalloproteinase-1 (MMP-1) and MMP-9 in the infected cells and berberine did not change the expression of MMP-1 and MMP-9. These data suggest that berberine inhibits C. pneumoniae infection-induced HEp-2 cell invasion through suppressing HEp-2 cell adhesion and migration, but not through changing the expression of MMP-1 and MMP-9.

Dongxiao Li,Liangjiang Wang,Shaolei Teng,Guoguang Zhang,Lijia Guo,Qian Mao,Wei Wang,Min Li,Liang Chen 한국식물학회 2012 Journal of Plant Biology Vol.55 No.4

Bacterial leaf streak (BLS), caused by the pathogen Xanthomonas campestris pv. Oryzicola, is a major rice disease in tropical and subtropical regions of Asia. Rice proteins responsive to BLS are still not well characterized. We took a proteomics approach to identify the proteins that are up-regulated in rice leaves after infection. Approximately 1,500 protein spots were detected on each 2-D gel after silver-staining; those with increased protein levels were selected for MALDI-TOF-MS analysis. We identified 32 up-regulated proteins that might be involved in disease resistance signal transduction, pathogenesis, and regulation of cell metabolism. By using publicly available microarray data, we determined the mRNA transcripts of 23 proteins expressed in the leaves. Seven genes were analyzed by northern blots, which demonstrated that transcript levels were increased after bacterial infection. Our findings help elucidate the molecular mechanisms underlying BLS and provide a solid foundation for further research on the functions of relevant genes.

BACKGROUND: In the present study, a novel tissue engineering bone graft including platelet rich plasma gel (PRP gel), human umbilical mesenchymal stem cells (HUMSCs) and nanohydroxyapatite/polyamide 66 (nHA-PA66) was constructed. We explored whether the composite scaffolds could enhance the angiogenesis and bone repair capacity in rat femoral large bone defect (LBD). This study aimed to provide evidence for the clinical application of the composite scaffold in LBD treatment. METHODS: PRP was prepared, the platelets and growth factors were measured. HUMSCs were isolated and identified. the osteogenic capacity of PRP in vitro was measured. Then HUMSCs-PRP-gel/nHA-PA66 composite scaffolds were synthesized and observed. The proliferation and osteogenesis differentiation of HUMSCs on the composite scaffold was measured. The angiogenic capacity of PRP in vitro was measured by capillary-like tube formation assay. Finally, the angiogenesis and bone repair capacity of the composite scaffolds was measured in rat LBD. RESULTS: PRP contained high level of platelets and growth factors after activation, and promoted osteogenic and angiogenic differentiation in vitro. The HUMSCs-PRP-gel/nHA-PA66 composite scaffold was porosity and promoted the proliferation and osteogenesis differentiation of HUMSCs. At 12th weeks, more micro-vessels and new bone were formed around the composite scaffolds compared with other groups, the defect was almost repaired. CONCLUSION: Our study for the first time identified that the combination of PRP gel, HUMSCs and nHA-PA66 scaffold could significantly promote angiogenesis and bone regeneration in rat LBD, which may have implications for its further application in clinical LBD treatment.

Zhiqiang Li,Binghua Zhou,Debin Teng,Wei-min Yang,Daohong Qiu 한국자원공학회 2018 Geosystem engineering Vol.21 No.2

Disordered mining activities have significantly affected the eco-geological environment of groundwater in mining area. Based on the fuzzy set theory, this paper considered three factors: the quantity of groundwater resources, groundwater environmental quality and groundwater vulnerability, and established a multi-index and multi-parameter non-linear evaluation system to make a comprehensive evaluation of the groundwater environment in the mining area. The results showed that the groundwater eco-geological environmental issues in this region were serious. The distribution area of poor quality of groundwater environment was very large, accounting for 72.5% of the studied area, and it mainly distributed in the middle and southern regions. The areas with general groundwater quality covered about 19.0% and mainly distributed in the central and northern parts in a strip shape. The areas with good groundwater quality covered about 8.5% and distributed sporadically. Moreover, in the study area, because the groundwater vulnerability was at a high level and the groundwater environmental quality was poor, the groundwater was extremely susceptible to contamination. Therefore, the groundwater environment in the area should be significantly protected during coal mining. In addition, the predicted results can provide a scientific reference for the planning and sustainable development of large coalfields.
