2Randomized controlled trial: Moxibustion and acupuncture for the treatment of Crohn's disease显示文摘AIM: To evaluate the clinical efficacy and safety of acupuncture and moxibustion for the treatment of active Crohn's disease(CD).METHODS: Ninety-two patients were equally and randomly divided into the treatment group and received herb-partitioned moxibustion combined with acupuncture, and the control group received wheat bran-partitioned moxibustion combined with superficial acupuncture. The patients received three treatment sessions per week for 12 wk and were followed up for 24 wk. The main outcome was evaluated using the CD Activity Index(CDAI) score, and the secondary outcomes were evaluated using laboratory indicators such as hemoglobin(HGB), C-reactive protein(CRP), erythrocyte sedimentation rate, quality-of-life, endoscopic ratings, and intestinal histology scores.RESULTS: The CDAI scores of both the treatment and control groups were significantly reduced after treatment compared with those measured before treatment. However, the degree of improvement in the treatment group was significantly greater than that of the control group. The improvement in symptoms in patients of the treatment group was sustained at follow-up, whereas that of the control group was not. The overall efficacy of the treatment was significantly greater than that of the control. Both groups demonstrated significant improvements in quality-of-life ratings after treatment, but the improvement was significantly greater in the treatment group than in the control group. In addition, the patients in the treatment group showed significantly increased HGB and significantly decreasedCRP levels and histopathological scores at the end of treatment, whereas the control group did not exhibit significant changes.CONCLUSION: Moxibustion with acupuncture provided significant therapeutic benefits in patients with active CD beyond the placebo effect and is therefore an effective and safe treatment for active CD.Chun-Hui Bao Ji-Meng Zhao Hui-Rong Liu Yuan Lu Yi-Fang Zhu Yin Shi Zhi-Jun Weng Hui Feng Xin Guan Jing Li Wei-Feng Chen Lu-Yi Wu Xiao-Ming Jin Chuan-Zi Dou Huan-Gan Wu 2014World Journal of Gastroenterology2014,20,31:19

4Serum levels of microRNAs can specifically predict liver injury of chronic hepatitis B显示文摘AIM:To investigate whether circulating microRNAs (miRNAs) can serve as molecular markers to predict liver injury resulted from chronic hepatitis B (CHB). METHODS:The profiles of serum miRNA expression were first generated with serum samples collected from 10 patients with CHB and 10 healthy donors (Ctrls) by microarray analysis. The levels of several miRNAs were further quantitated by real-time reverse transcriptionpolymerase chain reaction with serum samples from another 24 CHB patients and 24 Ctrls. Serum samples of 20 patients with nonalcohlic steatohepatitis (NASH) were also included for comparison. The comparison in the levels of miRNAs between groups (CHB, NASH and Ctrl) was analyzed with Mann-Whitney Utest. The correlation between miRNAs and clinical pathoparameters was analyzed using Spearman correlation analysis or canonical correlation analysis. The receiver-operator characteristic (ROC) curves were also generated to determine the specificity and sensitivity of each individual miRNA in distinguishing patients with CHB from Ctrls. RESULTS:miRNA profile analysis showed that 34 miRNAs were differentially expressed between CHB and Ctrl subjects, in which 12 were up-regulated and 22 down-regulated in CHB subject (fold change > 2.0 and P < 0.01). The median levels of miR-122, -572, -575 and -638 were significantly higher (P < 1.00 × 10 -5 ) while miR-744 significantly lower (P < 1.00 × 10 -6 ) in CHB compared with the Ctrl. The levels of miR-122, -572 and -638 were also higher (P < 1.00 × 10 -3 ) while the level of miR-744 lower in CHB (P < 0.05) than in NASH, although the difference between them was not as significant as that between CHB and Ctrl. ROC curve analysis revealed that the levels of miR-122, -572, -575, -638 and -744 in serum were sensitive and specific enough to distinguish CHB, NASH and Ctrl. Multivariate analysis further showed that the levels of these miRNAs were correlated with the liver function parameters. Most significantly, it was the scatter plot of principal component with the levels of these miRNAs, but not the parameters of liver function, which clearly distinguished CHB, NASH and Ctrl subjects. CONCLUSION:Serum levels of miR-122, -572, -575, -638 and -744 are deregulated in patients with CHB or NASH. The levels of these miRNAs may serve as potential biomarkers for liver injury caused by CHB and NASH.Hui Zhang Qing-Ya Li Zhi-Zhong Guo Yan Guan Jia Du Yi-Yu Lu Yi-Yang Hu Ping Liu Shuang Huang Shi-Bing Su 2012World Journal of Gastroenterology2012,18,37:15
5Novel chinmedomics strategy for discovering effective constituents from ShenQiWan acting on ShenYangXu syndrome显示文摘Elucidation of the efficacy of traditional Chinese medicine(TCM) is of importance for scientists of modern medicine to understand the value of TCM clinical experience, and it is necessary to have a biological language to scientifically describe the efficacy of TCM. With this background,Chinmedomics has been proposed by our team, which includes integrating serum pharmacochemistry and metabolomics technology, defining theory and research methods for expressing the efficacy of TCMs based on the biomarkers discovery of TCM syndrome and elucidating the efficacy of TCM formulae, discovering effective constituents, and finally elucidating the scientific value of TCM. In the present study, the innovative chinmedomics strategy was conducted to evaluate the therapeutic effects of Shen Qi Wan(SQW) acting on Shen Yang Xu(kidney-yang deficiency syndrome, KYDS). We analyzed the urine metabolic trajectory between the model and control groups, and identified the biomarkers by the multivariate analysis. We found that SQW caused significant restoration of abnormal metabolism of KYDs. Using the method of metabolomics, 17 potential urine biomarkers were analyzed through 4 repeated tests in our serial studies on SQW and KYDS. Under the premise of therapeutic efficacy, a total of 56 peaks were tentatively characterized in vivo by the use of serum pharmacochemistry. Correlation analysis between marker metabolites and in vivo constituents of SQW showed that 28 compositions had a close relationship with urine biomarkers of therapeutic effects, whichmight play a key role in the therapeutic effect of SQW. These compounds were imported into an online database to predict their targets. Twenty-three important potential targets were identified, which were related to the metabolism of steroid hormone, tryptophan utilization, and thyroid hormone. In conclusion, chinmedomics is a useful strategy for discovery of potentially effective constituents from complex TCM formulae.ZHOU Xiao-Hang ZHANG Ai-Hua WANG Liang TAN Yun-Long GUAN Yu HAN Ying SUN Hui WANG Xi-Jun 2016Chinese Journal of Natural Medicines2016,14,8:13

Methods 102 patients with HBV-GN were divided into 3 groups, according to the serum titer of the HBV DNA. 24-h urine protein excretion, and other parameters were measured. Renal biopsy were performed. The association between HBV DNA and the pathological stage of membranous nephropathy was analyzed in 78 patients with HBV-MN. 24-h urine protein excretion was used for the evaluation of the prognosis, and the relationship between HBV DNA and prognosis were analyzed. Results Several findings were demonstrated with the increase of serum HBV DNA: 24-h urine protein excretion, plasma cholesterol, and triglycerides increased significantly(P<0.05), while the plasma level of albumin decreased significantly(P<0.05); The changes of serum creatinine, C3 and C4 were found but no statistical significance. Glomerular deposition of HBVAg increased, and the pathological injury was more severe. The clinical remission rate was lower in the high replication group after treatment as compared with the low replication group(P<0.01). Conclusion With the increase of serum HBV DNA, the urine protein excretion and the kidney injury were more severe, and the clinical remission rate was decreased.JIANG Wei LIU Tuo DONG Hui XU Yan LIU Li Qiu GUAN Guang Ju LIU Xiang Chun 2015Biomedical and Environmental Sciences2015,28,3:13
7Roux-en-Y gastric bypass for Chinese type 2 diabetes mellitus patients with a BMI,28kg/m^2:a multi-institutional study显示文摘Roux-en-Y gastric bypass surgery(RYGB) has been demonstrated to be successful for treating type-II diabetes2mellitus(T2DM) patients with a body mass index(BMI),30 kg/m,but reports of RYGB for T2 DM patients with22 a BMI,28 kg/mare lacking.T2 DM patients with a BMI,28 kg/mwere prospectively recruited to participate in this study in four hospitals.The endpoint was T2 DM remission(defined by fasting blood glucose(FBG) level,110 mg/d L and hemoglobin(Hb)A1c level,6.0% at 12 months postoperatively).Predictors of remission were investigated by univariate and multivariate analyses.Eighty-six patients were assessed.Eighty-five patients underwent RYGB,with one conversion to open surgery.We compared the values of various variables before and after2 surgery.The mean BMI decreased from 24.68±2.12 to 21.72±2.43 kg/m(P,0.001).Fifty-eight(67.4%) patients were not treated by drugs or insulin after surgery,and 20 patients(23.3%) had complete remission of T2 DM at12 months after surgery with an acceptable number of complications.The mean Hb A1 c level in the remission group was significantly lower than that in the non-remission group.Patients with a higher weight,lower Hb A1 c level,higher C-peptide level,and higher FBG level were more likely to have T2 DM remission in multivariate2 analyses.In conclusion,RYGB was effective and safe for treating T2 DM patients with a BMI,28 kg/m.Complete remission can be predicted by cases having a higher weight,lower Hb A1 c level,higher C-peptide level,and higher FBG level.Hui Liang Wei Guan Yanling Yang Zhongqi Mao Yijun Mei Huan Liu Yi Miao 2015The Journal of Biomedical Research2015,29,2:13

9Efficacy analysis of flexible neuroendoscopy combined with dry-field techniques in the treatment of chronic subdural hematoma显示文摘Chronic subdural hematoma (CSDH) is a common and frequently occurring disease in neurosurgery, whose incidence accounts for around 10% of all intracranial hematomas. There have been many theories about the mechanism of CSDH, including acute subdural hematoma, slow hemorrhage after bridge vein injury, and traumatic subdural effusion evolution With improvements in medical imaging technology and related basic research, the perception of CSDH as an inflammatory vascular proliferative disease has gradually reached consensus In addition to head trauma, brain atrophy leading to expanded subdural space is the premise and primary reason for the occurrence of CSDH in the older adult population.Feng Guan Wei-Cheng Peng Hui Huang Bin Dai Guang-Tong Zhu Zhi-Yong Xiao Bei-Bei Mao Zhen-Yang Lin Quan Zhou Ya-Ping Wei Zhi-Qiang Hu 2019Chinese Medical Journal2019,,11:12
10Monitoring early responses to irradiation with dual-tracer micro-PET in dual-tumor bearing mice显示文摘AIM: To monitor the early responses to irradiation in primary and metastatic colorectal cancer (CRC) with 18 Ffluorothymidine ( 18 F-FLT) and 18 F-fluorodeoxyglucose ( 18 F-FDG) small-animal position emission tomography (micro-PET). METHODS: The primary and metastatic CRC cell lines, SW480 and SW620, were irradiated with 5, 10 and 20, l l l , Gy. After 24 h, the cell cycle phases were analyzed. A dual-tumor-bearing mouse model of primary and metastatic cancer was established by injecting SW480 and SW620 cells into mice. micro-PET with 18 F-FLT and 18 F-FDG was performed before and 24 h after irradiation with 5, 10 and 20 Gy. The region of interest (ROI) was drawn over the tumor and background to calculate the ratio of tumor to non-tumor (T/NT) in tissues. Immunohistochemical assay and Western blotting were used to examine the levels of integrin β3, Ki-67, vascular endothelial growth factor receptor 2 (VEGFR2) and heat shock protein 27 (HSP27). RESULTS: The proportion of SW480 and SW620 cells in the G 2 -M phase was decreased with an increasing radiation dose. The proportion of SW480 cells in the G 0 -G 1 phase was increased from 48.33% ± 4.55% to 87.09% ± 7.43% (P < 0.001) and that of SW620 cells in the S-phase was elevated from 43.57% ± 2.65% to 66.59% ± 7.37% (P = 0.021). In micro-PET study, with increasing dose of radiation, 18 F-FLT uptake was significantly reduced from 3.65 ± 0.51 to 2.87 ± 0.47 (P = 0.008) in SW480 tumors and from 2.22 ± 0.42 to 1.76 ± 0.45 (P = 0.026) in SW620 tumors. 18 F-FDG uptake in SW480 and SW620 tumors was reduced but not significantly (F = 0.582, P = 0.633 vs F = 0.273, P = 0.845). Dose of radiation was negatively correlated with 18 F-FLT uptake in both SW480 and SW620 tumors (r = -0.727, P = 0.004; and r = -0.664, P = 0.009). No significant correlation was found between 18 F-FDG uptake and radiation dose in SW480 or SW620 tumors. HSP27 and integrin β3 expression was higher in SW480 than in SW620 tumors. The T/NT ratio for 18 F-FLT uptake was positively correlated with HSP27 and integrin β3 expression (r = 0.924, P = 0.004; and r = 0.813, P = 0.025). CONCLUSION: 18 F-FLT is more suitable than 18 F-FDG in monitoring early responses to irradiation in both primary and metastatic lesions of colorectal cancer.Hui Wang, Jia-He Tian, Bai-Xuan Xu, Zhi-Wei Guan, ChangBin Liu, Rui-Min Wang, Ying-Mao Chen, Jin-Ming Zhang, Nuclear Medicine Department, The General Hospital of the Chinese People’s Liberation Army and Military Medical Postgraduate College, Beijing 100853, China Bo Liu, Department of Hepatobiliary Surgery, The General Hospital of the Chinese People’s Liberation Army and Military Medical Postgraduate College, Beijing 100853, China Bao-Lin Qu, Department of Radiation Oncology, The General Hospital of the Chinese People’s Liberation Army and Military Medical Postgraduate College, Beijing 100853, China 2010World Journal of Gastroenterology2010,16,43:10
11Ginsenoside Rb1 Attenuates Isoflurane/surgery-induced Cognitive Dysfunction via Inhibiting Neuroinflammation and Oxidative Stress显示文摘Objective Anesthetic isoflurane plus surgery has been reported to induce cognitive impairment. The underlying mechanism and targeted intervention remain largely to be determined. Ginsenoside Rb1 was reported to be neuroprotective. We therefore set out to determine whether ginsenoside Rb1 can attenuate isoflurane/surgery-induced cognitive dysfunction via inhibiting neuroinflammation and oxidative stress. Methods Five-months-old C57BL/6J female mice were treated with 1.4% isoflurane plus abdominal surgery for two hours. Sixty mg/kg ginsenoside Rb1 were given intraperitoneally from 7 days before surgery. Cognition of the mice were assessed by Barnes Maze. Levels of postsynaptic density-95 and synaptophysin in mice hippocampus were measured by Western blot. Levels of reactive oxygen species, tumor necrosis factor-α and interleukin-6 in mice hippocampus were measured by ELISA. Results Here we show for the first time that the ginsenoside Rb1 treatment attenuated the isoflurane/surgery-induced cognitive impairment. Moreover, ginsenoside Rb1 attenuated the isoflurane/surgery-induced synapse dysfunction. Finally, ginsenoside Rb1 mitigated the isoflurane/surgery-induced elevation levels of reactive oxygen species, tumor necrosis factor-α and interleukin-6 in the mice hippocampus. Conclusion These results suggest that ginsenoside Rb1 may attenuate the isoflurane/surgery-induced cognitive impairment by inhibiting neuroinflammation and oxidative stress pending future studies.MIAO Hui Hui ZHANG Ye DING Guan Nan HONG Fang Xiao DONG Peng TIAN Ming 2017Biomedical and Environmental Sciences2017,30,5:9
12Ginsenoside Rg1 Attenuates Isoflurane-induced Caspase-3 Activation via Inhibiting Mitochondrial Dysfunction显示文摘Objective The inhalation anesthetic isoflurane has been shown to induce mitochondrial dysfunction and caspase activation, which may lead to learning and memory impairment. Ginsenoside Rg1 is reported to be neuroprotective. We therefore set out to determine whether ginsenoside Rg1 can attenuate isoflurane-induced caspase activation via inhibiting mitochondrial dysfunction. Methods We investigated the effects of ginsenoside Rg1 at concentrations of 12.5, 25, and 50 μmol/L and pretreatment times of 12 h and 24 h on isoflurane-induced caspase-3 activation in H4 na?ve and stably transfected H4 human neuroglioma cells that express full-length human amyloid precursor protein(APP)(H4-APP cells). For mitochondrial dysfunction, we assessed mitochondrial permeability transition pore(m PTP) and adenosine-5'-triphosphate(ATP) levels. We employed Western blot analysis, chemiluminescence, and flowcytometry. Results Here we show that pretreatment with 50 μmol/L ginsenoside Rg1 for 12 h attenuated isoflurane-induced caspase-3 activation and mitochondrial dysfunction in H4-APP cells, while pretreatment with 25 and 50 μmol/L ginsenoside Rg1 for 24 h attenuated isoflurane-induced caspase-3 activation and mitochondrial dysfunction in both H4 na?ve and H4-APP cells. Conclusion These data suggest that ginsenoside Rg1 may ameliorate isoflurane-induced caspase-3 activation by inhibiting mitochondrial dysfunction. Pending further studies, these findings might recommend the use of ginsenoside Rg1 in preventing and treating isoflurane-induced neurotoxicity.MIAO Hui Hui ZHEN Yu DING Guan Nan HONG Fang Xiao XIE Zhong Cong TIAN Ming 2015Biomedical and Environmental Sciences2015,28,2:9

16Sensitivity-enhanced surface plasmon resonance sensor utilizing a tungsten disulfide (WS_2) nanosheets overlayer显示文摘Tungsten disulfide(WS_2), as a representative layered transition metal dichalcogenide(TMDC) material, possesses important potential for applications in highly sensitive sensors. Here, a sensitivity-enhanced surface plasmon resonance(SPR) sensor with a metal film modified by an overlayer of WS_2 nanosheets is proposed and demonstrated. The SPR sensitivity is related to the thickness of the WS_2 overlayer, which can be tailored by coating a WS_2 ethanol suspension with different concentrations or by the number of times of repeated post-coating.Benefitting from its large surface area, high refractive index, and unique optoelectronic properties, the WS_2 nanosheet overlayer coated on the gold film significantly improves the sensing sensitivity. The highest sensitivity(up to 2459.3 nm∕RIU) in the experiment is achieved by coating the WS_2 suspension once. Compared to the case without a WS_2 overlayer, this result shows a sensitivity enhancement of 26.6%. The influence of the WS_2 nanosheet overlayer on the sensing performance improvement is analyzed and discussed. Moreover, the proposed WS_2 SPR sensor has a linear correlation coefficient of 99.76% in refractive index range of 1.333 to 1.360. Besides sensitivity enhancement, the WS_2 nanosheet overlayer is able to show additional advantages, such as protection of metal film from oxidation, tunability of the resonance wavelength region, biocompatibility, capability of vapor,and gas sensing.HAO WANG HUI ZHANG JIANGLI DONG SHIQI HU WENGUO ZHU WENTAO QIU HUIHUI LU JIANHUI YU HEYUAN GUAN SHECHENG GAO ZHAOHUI LI WEIPING LIU MIAO HE JUN ZHANG ZHE CHEN YUNHAN LUO 2018Photonics Research2018,6,6:8

18Designing near-natural planting patterns for plantation forests in China显示文摘Background: China has a long tradition of managing planted forests. Different species of Populus, Eucalyptus, Larix, Cunninghamia and Pinus are planted to satisfy the local demand for wood products and provide ecological services at the same time. Evidence of the greater resilience of natural forests provides the motivation to develop asymmetric planting patterns, which is the focus of this study. We present a new method for designing plantation patterns that follow those observed in natural ecosystems and to maintain some regularity for operational convenience. Methods: Based on the uniform angle index, we analyzed the spatial structure of six natural forests in different regions of China. The uniform angle index describes the degree of spatial uniformity of the n nearest neighbors of a given reference tree. Accordingly, we identified all possible patterns of a neighborhood group within a regular planting pattern and developed a method to optimize planting point arrangements that contain some randomness as well as a minimum degree of regularity. Results:(1) There are 13 types of structural units in a regular planting, including seven random units, five even units and one cluster unit;(2) Five near-natural arrangements are presented with a minimum proportion of 50% of random units. These five arrangements represent a combination of regularity for operational convenience and asymmetry. Conclusions: The new planting patterns developed in this study are expected to increase the asymmetric competition and resilience of these important ecosystems. Some experimental plantings, based on our findings, have already been established, e.g., in Pinus tabulaeformis plantations in Tianshui, Gansu Province, and in a Populus deltoides plantation in Fangshan near Beijing.Gongqiao Zhang Gangying Hui Yanbo Hu Zhonghua Zhao Xiuling Guan Klaus von Gadow Ganggang Zhang 2019Forest Ecosystems2019,6,3:6
19Atorvastatin attenuates surgery-induced BBB disruption and cognitive impairment partly by suppressing NF-κB pathway and NLRP3 inflammasome activation in aged mice显示文摘In clinic,perioperative neurocognitive disorder is becoming a common complication of surgery in old patients.Neuroinflammation and blood-brain barrier(BBB)disruption are important contributors for cognitive impairment.Atorvastatin,as a strong HMG-CoA reductase inhibitor,has been widely used in clinic.However,it remains unclear whether atorvastatin could prevent anesthesia and surgery-induced BBB disruption and cognitive injury by its anti-inflammatory property.In this study,aged C57BL/6J mice were used to address this question.Initially,the mice were subject to atorvastatin treatment for 7 days(10 mg/kg).After a simple laparotomy under 1.5%isoflurane anesthesia,Morris water maze was performed to assess spatial learning and memory.Western blot analysis,immunohistochemistry,and enzyme-linked immunosorbent assay were used to examine the inflammatory response,BBB integrity,and cell apoptosis.Terminal-deoxynucleotidyl transferase mediated nick end labeling assay was used to assess cell apoptosis.The fluorescein sodium and transmission electron microscopy were used to detect the permeability and structure of BBB.The results showed that anesthesia and surgery significantly injured hippocampal-dependent learning and memory,which was ameliorated by atorvastatin.Atorvastatin could also reverse the surgery-induced increase of systemic and hippocampal cytokines,including IL-1β,TNF-α,and IL-6,accompanied by inhibiting the nuclear factor kappa-B(NF-κB)pathway and Nucleotide-Binding Oligomerization Domain,or Leucine Rich Repeat and Pyrin Domain Containing 3(NLRP3)inflammasome activation,as well as hippocampal neuronal apoptosis.In addition,surgery triggered an increase of BBB permeability,paralleled by a decrease of the ZO-1,occludin,and Claudin 5 proteins in the hippocampus.However,atorvastatin treatment could protect the BBB integrity from the impact of surgery,by up-regulating the expressions of ZO-1,occludin,and Claudin 5.These findings suggest that atorvastatin exhibits neuroprotective effects on cognition in aged mice undergoing surgery.Pengfei Liu Quansheng Gao Lei Guan Yanting Hu Jingwen Jiang Teng Gao Weixuan Sheng Xinying Xue Hui Qiao Tianzuo Li 2021Acta Biochimica et Biophysica Sinica2021,53,5:6
