Improving soil quality while achieving higher productivity is the major challenge in the agricultural industry. Wheat(Triticum aestivum L.)–maize(Zea mays L.)(W–M) rotation is the dominant planting pattern in the huang-HuaiHai Plain and is important for food security in China. However, the soil quality is deteriorating due to the W–M rotation’s long-term, intensive, and continuous cultivation. Introducing legumes into the W–M rotation system may be an effective way to improve soil quality. In this study, we aimed to verify this hypothesis by exploring efficient planting systems(wheat–peanut(Arachis hypogaea L.)(W–P) rotation and wheat rotated with maize and peanut intercropping(W–M/P)) to achieve higher agricultural production in the huang-Huai-Hai Plain. Using traditional W–M rotation as the control, we evaluated crop productivity, net returns, soil microorganisms(SMs), and soil organic carbon(SOC) fractions for three consecutive years. The results indicated that wheat yields were significantly increased under W–P and W–M/P(382.5–579.0 and 179.8–513.1 kg ha-1, respectively) compared with W–M. W–P and W–M/P provided significantly higher net returns(58.2 and 70.4%, respectively) than W–M. W–M/P and W–M retained the SOC stock more efficiently than W–P, increasing by 25.46–31.03 and 14.47–27.64%, respectively, in the 0–20 cm soil layer. Compared with W–M, W–M/P improved labile carbon fractions;the sensitivity index of potentially mineralizable carbon, microbial biomass carbon(MBC), and dissolved organic carbon was 31.5, 96.5–157.2, and 17.8% in 20–40, 10–40, and 10–20 cm soil layers, respectively. The bacterial community composition and bacteria function were altered as per the soil depth and planting pattern. W–M/P and W–M exhibited similar bacterial community composition and function in 0–20 and 20–40 cm soil layers. Compared with W–P, a higher abundance of functional genes, namely, contains mobile elements and stress-tolerant, and a lower abundance of genes, namely,

The present study was aimed at determining the effects of Tongqiao Huoxue Decoction （TQHXD） on the Ca2＋-CaMKII-CREB pathway and the memory and learning capacities of rats with vascular dementia （VD）. The rat VD model was established by using an improved bilateral carotid artery ligation method. The Morris water maze experiment was used to evaluate the ethology of the VD rats following treatments with TQHXD at 3.01, 6.02, and 12.04 ***-1 per day for 31 days. At the end of experiment, the hippocampus were harvested and analyzed. Western blotting and RT-PCR were used to measure the expression levels of calmodulin-binding protein kinase II（CaMKII）, protein kinase A（PKA）, cAMP-response element binding protein（CREB）, and three N-methyl-D-aspart^c acid receptor subunits （NR1, NR2A, and NR2B）. Our results revealed that TQHXD could alleviate the loss of learning abilities and increase the memory capacity （P 〈 0.05 and P 〈 0.01 vs the model group, respectively）. The treatment with 6.02 and 12.04 ***-1 of TQHXD significantly up-regulated the Ca2＋-CaMKII-CREB pathway in the hippocampus. In conclusion, TQHXD showed therapeutic effects on a bilateral carotid artery ligation-induced vascular dementia model, through the up-regulation of calcium signalling oathwavs.

Background and Objective: Traditional Chinese medicine (TCM) is a well established and time-honored practice in China, employing syndrome differentiation as a basis for the treatment of disease. According to different TCM syndrome typing findings, combining modern medical methods with TCM approaches can improve the quality of life and comprehensive effect on patients with nasopharyngeal carcinoma (NPC). This study investigated the relationship between TCM syndrome typing and imaging characterization to radiosensitivity as to provide objective evidence for the integration of Chinese and modern medical approaches in the treatment of NPC. Methods: Prior to treatment, TCM syndrome typing, computed tomography (CT) and magnetic resonance imaging (MRI) were performed on 147 patients pathologically classified with NPC. The status of tumor remission was radiologically evaluated at accumulated doses of 20 Gy, 40 Gy and 60 Gy, and at 3 months after completion of radiotherapy. Statistical results were analyzed by the Friedman and K-W test procedures. Results: Prior to treatment, TCM syndrome typing of NPC included Lung Heat, Blood Stasis, Phlegm Congealment and Blood Stasis-Phlegm Congealment. Lung Heat typing accounted for the highest proportion at 34.7% (51/147), followed by Phlegm Congealment at 32.7% (48/147), Blood Stasis at 17.0% (25/147) and Blood Stasis-Phlegm Congealment at 15.7% (23/147). Radiological imaging demonstrated a higher incidence of cervical lymph node metastases in Phlegm Congealment and Blood Stasis-Phlegm Congealment types (P < 0.05), while Blood Stasis and Blood Stasis-Phlegm Congealment types were more prone to skull base invasion (P < 0.05). Residual tumor size was larger in Blood Stasis and Blood Stasis-Phlegm Congealment types than in Lung Heat and Phlegm Congealment types after 3 months of treatment (P < 0.05). Conclusions: Different radiological manifestations were observed in TCM syndrome typed NPC patients, with lesser radiosensitivity demonstra

Effect of Intensive Greenhouse Vegetable Cultivation on Selenium Availability in Soil

引用

Pedosphere 2015年第3期25卷 343-350页

作者： FU ming-ming huang Biao JIA Meng-Meng HU Wen-You SUN Wei-xia D.C.WEINDORF CHANG Qing Key Laboratory of Soil Environment and Pollution Remediation Institute of Soil ScienceChinese Academy of Sciences University of Chinese Academy of Sciences Department of Plant and Soil Science Texas Tech University Geological Survey of Jiangsu

Soil properties dramatically change after long-term greenhouse vegetable cultivation, which further affects soil selenium （Se） nutritional status and plant Se uptake. An evaluation of Se availability after long-term greenhouse vegetable cultivation （CVC） can help in better understanding its influential factors under GVC conditions and will also facilitate further regulation of soil Se nutrition in GVC systems. Two typical GVC bases were chosen： one with clayey and acidic soil in Nanjing, southern China, and the other with sandy alkaline soil in Shouguang, northern China. Twenty-seven surface soil samples at the Nanjing base and 61 surface soil samples at the Shouguang base were collected according to cultivation duration and cultivation intensity. Soil properties including soil available Se （PO4^3--Se） and total Se （T-Se） were analyzed. The results showed that soil PO4^3--Se was significantly and negatively correlated with soil Olsen-P, available K （A-K）, and electrical conductivity （EC） at the Nanjing base. At the Shouguang base, however, no significant correlation was found between soil PO4^3--Se and Olsen-P and EC, and soil PO4^3--Se increased with increasing soil organic matter （OM）. Intensively utilized greenhouse vegetable cultivation caused significant changes in soil properties and further affected soil Se availability. Due to different management practices, the dominant factors affecting Se availability varied between the two GVC bases. At the Nanjing base, the dominant influential factor on soil Se availability was soil nutritional status, especially Olsen-P and A-K status. At the Shouguang base, where organic fertilizers were applied at high rates, soil OM was the dominant influential factor.

Chinese Journal of Integrative Medicine 2017年第7期23卷 535-542页

作者： HAN Bin ZHU Chun-xia SHI Wan huang Hui-zhu HU Xu-guang ZHOU xiao-ming LEI ming LI Zhong College of Traditional Chinese Medicine Guangdong Pharmaceutical University Guangzhou 510006 China

Objective：To explore the effects of Rhizoma Polygoni Cuspidati and Ramulus Cinnamomicompatibility（PR） on uric acid metabolism and the expression of urinary neutrophil gelatinase-associated lipocalin（NGAL） and kidney injury molecule-1（KIM-1） in rats with hyperuricemia. Methods：Seventy male Sprague Dawley（SD） rats were randomly divided into 7 groups with 10 rats per group, including the normal group, model group, allopurinol group, benzbromarone group and PR groups at 3 doses（3.5, 7, 14 g/kg）. Except the normal group, rats of the other groups were intragastrically administered 100 mg/kg hypoxanthine and 250 mg/kg ethambutol, and subcutaneously injected with 200 mg/kg potassium oxonate. All rats were continuously modeled for 17 days, and gavaged with corresponding drugs. The rats of the normal and model groups were gavaged with saline, once a day, for 2 weeks. The levels of serum uric acid（SUA）, blood urea nitrogen（BUN） and creatinine（Cr） were determined. In addition, the contents of NGAL and KIM-1 in urine and the m RNA and protein expressions of xanthine oxidase（XOD） in liver of hyperuricemia rats were measured by reverse transcription polymerase chain reaction（RT-PCR） and Western blot, respectively. Moreover, the pathological changes of kidney were analyzed by hematoxylin and eosin（HE） stain method. Results：Compared with the normal group, the levels of SUA, BUN, NGAL and KIM-1 and the expressions of hepatic XOD m RNA and protein in the hyperuricemia rats were increased significantly（P〈0.01）. PR significantly decreased the levels of SUA, BUN, NGAL and KIM-1 and down-regulated the m RNA and protein expressions of hepatic XOD（P〈0.05 or P〈0.01）. In addition, the pathological changes of kidney were significantly suppressed by oral administration of PR. Conclusions：PR ameliorated uric acid metabolism and protected renal function, the underlying mechanism was mediated by decreasing the levels of SUA, BUN, NGAL and KIM-1, inhibiting the expression of hepatic XOD and amelior

目的:为了研究着火车辆停靠朝向对隧道顶棚温度分布和烟气运动特性的影响。方法:采用数值模拟结合比尺模型试验的方法,分析在不同纵向风速和火源功率下,横向、纵向两种典型火源的顶棚最高温升和烟气回流规律。结果:相比纵向火源,横向火源烟气阻塞效应更强,顶棚附近烟气运动速度更快,烟气卷吸量更大;且火源占隧道宽度比例较大,烟气较早进入一维蔓延,使得隧道顶棚温度更低。随火源功率和纵向风速的增大,两种火源朝向下的顶棚温度差距越大,30 MW火源下顶棚最高温度的差值可达57%。较纵向火源,横向火源隧道顶棚温度更低,烟气热浮力减小,烟气运动衰弱。随火源功率增加和纵向风速降低,回流长度差距逐渐增大,30 MW火源下最大差值为36 m。结论:横向火源烟气层热稳定性更弱,烟气沉降更为明显,即使在低风速下,近火源段烟气层也易被破坏。
