In order to explore the characteristics of soil enzyme activities under different types of plastic film mulching, we set up four different types of plastic film mulching models at Dongyang experimental base of Agricultural Sciences Academy in Shanxi Province in 2016, including common plastic film mulching(P), water-permeable plastic mulching film(SS), biodegradable plastic film mulching(SW), light degradation mulching(G), uncovered film covering in open field(CK) was used as control. The results showed that alkaline phosphatase and nitrate reductase under four kinds of coating treatments were higher than CK in all growth stages, while urease, catalase, and nitrite reductase under plastic film were lower than CK; Soil urease activity was highest in flare opening stage, with CK > G > SW > SS > P; Alkaline phosphatase activity was highest during harvest, SS, SW, P, and G treatments at 0~20 cm soil were 16.17%, 18.97%, 16.34%, and 14.56% highter than CK. The activity of nitrate reductase at 0~20 cm soil of SS, SW, P, and G treatments were 68.57%, 42.86%, 42.86%, and 25.71% higher than that of CK; Combining other factors such as maize yield, we found that the changes of soil alkaline phosphatase activity and nitrate reductase activity were highly significant positively correlated with soil respiration rate and maize yield(P<0.01), Soil hydrothermal and fertilization conditions at different growth stages caused corresponding changes in soil enzyme activity. Among them, SW and SS treatments had obviously effects on the temperature raising and water saving of maize soil during the early growth period, they also had the highest yield, with the highest corresponding alkaline phosphatase activity and nitrate reductase activity, and SW had considerable degradation performance. Therefore, biodegradable plastic film in the future can be used as an alternatives of common mulch film applied to dry farmland, at the same time, it can achieve the effect of relieving farmland residual film pollution.

Objective To evaluate the reproducibility of three-dimensional high-resolution magnetic resonance imaging (HR-MRI) for vessel wall in demonstration of intracranial atherosclerotic plaque enhancement and to explore the relationship between plaque enhancement and ischemic stroke. Methods Fifty-two patients with ischemic stroke underwent traditional head MRI, three-dimensionaltime of flight magnetic resonance angiography and HR-MRI on a 3.0T MRI scanner.Each identified intracranial plaque was classified as either culprit (the only or most stenotic lesion upstream from a stroke) or non-culprit (not the most stenotic lesion upstream from a stroke or not within the vascular territory of a stroke). The degree of plaque enhancement was graded by two independent radiologists. The degree of plaque enhancement and luminal stenosis were compared between the culprit group and the non-culprit group by using Mann-Whitney U test.Binary logistic regression analysis was performed to assess the relation between the degree of plaque enhancement and culprit plaques. Results Total 118 plaques were identified in 52 patients with ischemic stroke (52 culprit plaques and 66 non-culprit plaques). The degree of enhancement was rated as strong, moderate and none in 40, 9 and 3 culprit plaques, and in 4, 24 and 38 non-culprit plaques. Both intra-observer and inter-observer agreement were high for identification of plaque enhancement (kappa＞0.75). For culprit plaques group, the degree of plaque enhancement(Z=-7.787, P<0.01) and luminal stenosis (Z=-5.327, P<0.01) were significantly higher than those in the non-culprit group.Binary logistic regression analysis revealed that strong enhancement of plaques was independently associated with culprit plaques (OR:74.3, 95%CI:15.0-367.1, P<0.01). Conclusions Three-dimensional HR-MRI detects enhancement of intracranial plaques with high reproducibility.Enhancement is more common in culprit plaques and is associated with the likelihood of ischemic stroke.

The incidence of cervical cancer is closely related to human papillomavirus infection. Therefore, HPV genotyping is of great significance for the prevention, diagnosis and treatment of cervical cancer, the HPV detection technology has been continuously improved in recent years. Different HPV subtypes would lead to different clinical symptoms, so the limitations of some traditional HPV detection methods are gradually highlighted because they can not give genotype information through detection. At present, HPV genotyping is mainly dependent on a variety of HPV DNA detection technology. However, the principles and the scopes of applications of these technologies are different, bringing some troubles to the clinical selection of HPV detection methods. Here, we gave a brief introduction to widely applied HPV DNA genotyping methods, and compared the scopes of applications of each methods, so as to provide a reference for clinical selection of appropriate HPV detection methods.

Splenomegaly is a common pathological change of portal hypertension in liver cirrhosis and can progress to hypersplenism, leading to the reduction in blood cells and increasing the risk of clinical bleeding and infection. Splenectomy is an important method for the treatment of splenectomy with hypersplenism, but it faces the risks of infection, surgical bleeding, postoperative thrombosis, and postoperative pancreatic fistula. However, with the gradual deepening of modern research, it has been found that patients with liver cirrhosis have a certain degree of improvement after splenectomy, such as the reduced risk of gastrointestinal bleeding, a reduction in portal venous pressure, the improvement in the hemodynamics of internal organs, the promotion of liver tissue regeneration, the improvement in liver fibrosis, the regulation of immune function, the improvement in nutritional status, and the reduced risk of liver cancer. With reference to available clinical and experimental studies, this article reviews the influence of splenectomy on the course of liver cirrhosis and actively explores related mechanism, in order to provide reliable reference and basis for the selection and implementation of splenectomy in clinical practice.

To control the formation of polycyclic aromatic hydrocarbons (PAHs) and reduce the carbon deposition phenomenon on the surface of oxygen earner, the mechanical mixing method to prepare CaSO4/bentonite oxygen carrier was adopted to react with coal in a simulated chemical-looping combustion (CLC) fuel reactor. Gas chromatography was employed for qualitative and quantitative analysis on PAHs. The emission characteristics of PAHs were discussed at different coal types, temperatures and oxygen carriers/coal ratios. The results show that with the volatile increasing, the total amount of PAHs formation at different coal types is in the order as anthracite< bituminous coal 1< bituminous coal 2< bituminous coal 3. PAHs formation is also influenced by carbon content, n( H )/n( C ) and n( O )/n( C ) ratio. In the CLC process, 2-ring and 3-ring PAHs are predominant as 4-ring and 5-ring PAHs are relatively small, while 6- ring PAHs is not produced. When the temperature is 900 ℃ and oxygen carrier/coal ratio is 2. 4, the total amount of PAHs formation is the least in the reaction of CaSO4/bentonite oxygen earner and bituminous coal 3.

The agricultural internet of things (Ag-IoT), which promotes deep integration of modern information and agricultural technology, has become the focus in precision agriculture research. However, it is inconvenient to replace the battery for sensor nodes in real applications due to the facts of complicated farmland environment, large monitoring area, numerous sensor nodes and long crop growth cycle, which brings a big challenge to the power supply of Ag-IoT sensor node. Fortunately, with the rapid development of the electronic technology, the power consumption for the wireless sensor node decreases quickly, which has reached the μW level, and the ambient energy harvesting technology makes it possible for Ag-IoT sensor nodes to have self-power supply and free maintenance. The traditional energy harvesting devices are always limited to only one sort of ambient energy and have big size with poor reliability. This paper proposed a novel hybrid ambient energy harvesting integration system, focusing on the RF (radio frequency) energy and vibration energy which are rich in the environment. A new type of integrated hybrid ambient energy harvesting device was designed, and the RF energy and vibration energy could be harvested at the same time by the combination of the RF antenna and the piezoelectric ceramic effectively. The system consisted of antenna, matching network, piezoelectric module and rectifier. The antenna received the RF(radio frequency) electromagnetic wave and the matching network improved the power transmission from the antenna to the rectifier, and 2 Schottky diodes and 2 capacitances were used to form the double-voltage rectifier. To reduce the size and improve the conversion efficiency, the rectifier was designed to rectify both the RF electromagnetic wave and the low frequency vibration signal. The converted DC (direct current) power was saved in a super capacitance which had high quality factor with very low leakage current. The energy harvesting antenna was designed in an array with 4 antenna elements in order to collect more RF energy. It was simulated and optimized at the frequency of 1.9 GHz (3G band) by using 3D (three-dimensional) electromagnetic simulation tool HFSS (high frequency structure simulator), and the matching network was designed and optimized by using the ADS (advanced design system). The antenna was implemented by the common FR4 printed circuit board which had low cost. The energy harvesting system was measured by the VNA(vector network analyzer) and oscilloscope, and the measured return loss of the antenna was -20.5 dB, which agreed well with the simulation results. The maximum output power of the harvested RF energy could reach 38 mW, and meanwhile, considering the typical low vibration frequency in farmland enviroment, we used 10 Hz as the vibration frequency for the vibration energy converting measurement. The measured maximum output power of the harvested vibration energy could reach 25 mW, which met the power requirement of the low power consumption sensor node. This device not only improves the reliability for the system power supply and the adaptive capacity to the environment, but also reduces the size of the device obviously, providing a new way for solving the problem of sensor node power supply during the rapid development of Ag-IoT.

Dry red wines can be sourced from the Ningxia and Xinjiang regions of China. This study aims to characterize the taste quality, according to the conventional and easily measurable polyphenol series indices. The UV-Vis spectrophotometer was used to detect the conventional polyphenols in wine. A predictive model was constructed to evaluate the astringency and aftertaste of dry red wine using the polyphenol indices. A total of 50 (Cabernet Sauvignon) dry red wines were selected as the research objects (20 from Ningxia and 30 from Xinjiang, each from different small producing areas). The total acidity, volatile acidity, and pH of the wines were tested to evaluate the acidity, according to GB/T 15038-2006. The antioxidant activity of wine was determined by DPPH scavenging activity. Total phenols were determined with the UV-Vis spectrophotometer using the Folin-Ciocalteu method. Flavanol content was determined by p-DMACA hydrochloric acid. The contents of tartrate (A320), flavonol (A360), and total anthocyanins (A520) in the wines were determined at different absorbance levels. The aftertaste and astringent sensation were evaluated using the quantitative sensory description in Panel Check software. Correlation analysis (CA) was used to analyze the interaction between the indices of the wine polyphenol series, and linear discriminant analysis (LDA) was to easily distinguish different regions. The modeling samples were analyzed with the principal component analysis. The taste quality of wine samples was characterized and predicted with partial least squares regression. The CA results indicated that there were significant differences (P<0.05) in the effects of total phenols, anthocyanins, flavanols, and flavonols on the astringency and aftertaste of the dry red wines. However, there was a minimal impact of tartrate on the aftertaste. Furthermore, the total acids and pH had no significant (P>0.05) effect on the astringency of the wine. Taking the Yongning region of Ningxia as an example, LDA easily differentiated dry red wine samples from the Yongning of Ningxia and the Xinjiang region using polyphenol series indices. Two discriminant functions generated by LDA were used to explain 80.8% and 19.2% of the variance, respectively. The accurate discriminant rate of 80.0% was obtained after classification. While there was the correct discriminant rate of 62% after the cross-validation. The sensory evaluation showed that the astringency scores were 6.18 and 5.70, in Ningxia and Xinjiang wine samples, respectively, while the aftertaste scores were 5.37 and 4.85, respectively. Therefore, the total phenols, anthocyanins, flavanols, flavonols, and DPPH contributed significantly to the astringency and aftertaste of wine. Tartrate mostly influenced the wine astringency, whereas the total acids and pH dominated the wine aftertaste. Polyphenol indices with cost-saving UV-Vis spectrophotometers can be expected to better assess the taste quality of dry red wine. The sample size can be increased to promote the taste quality of dry red wine for the accuracy and stability of the model. [ABSTRACT FROM AUTHOR]

① Bone marrow samples from 30 AML patients and 30 iron deficiency anemia patients were examined for UCA1 by RT-PCR. ② U937 and HL60 cells were divided into the groups 1, 2, and 3, respectively. Cells in the group 1 and group 2 were transfected with UCA1-siRNA (which can inhibit the expression of UCA1) and no-siRNA, respectively, and cells in the group 3 were blank controls (without any treatment). The cells were harvested at 24, 48 and 72 h after transfection, and the proliferation activity was measured by MTT assay. At 48 h after transfection, apoptosis was observed by flow cytometry. Wnt, β-catenin, and p-gsk-3ß proteins were detected by Western blotting at 48 h after transfection. Results The relative expression levels of UCA1 were 4. 96±1. 51 in AML patients and 1. 09±0. 93 in iron deficiency anemia patients, respectively, with statistically significant difference (P<0. 05). At 24, 48 and 72 h after transfection, the proliferation activity of U937 and HL-601 cells was lower in the group 1 than in the groups 2 and 3 (P<0. 05). The apoptosis rates of U937 cells in the groups 1, 2, and 3 were 34. 20%±1. 21%, 7. 21%±1. 41%, and 6. 84%±1. 53%； the apoptosis rates of Hl-60 cells in the groups 1, 2, and 3 were 34. 21%±1. 83%, 7. 20% ± 1. 56%, and 7. 85%±1. 93%, respectively. Compared with groups 2 and 3, the apoptosis rates of U937 and Hl-60 cells in the group 1 were higher (both P< 0. 05). Compared with groups 2 and 3, the relative expression levels of Wnt and β-catenin in U937 and HL-601 cells decreased, while the relative expression of p-gsk-3ß protein increased in the group 1（all P<0. 05）. Conclusion UCA1 expression in bone marrow mononuclear cells is elevated in AML patients in comparison with that of iron deficiency anemia patients. Inhibition of UCA1 expression can inhibit the proliferation and promote apoptosis of U937 and Hl-60 cells, which may be related to the inhibition of Wnt/β-catenin signaling pathway by UCA1.
