Abstract: OBJECTIVE: This study aimed to assess the specificity of auricular acupoints in responding to changes of qi and blood which, in traditional Chinese medicine, are considered as the fundamental substances in the human body for sustaining normal vital activity.METHODS: A miniature fiber optic system was used to invasively measure the diffuse reflectance spectra of three auricular acupoints, namely, Uterus (TF2), Gan (CO12) and Neifenmi (CO18), at different stages of menstruation, when the female body exhibits regular changes of qi and blood. The spectra of different acupoints were compared to find their difference in responding changes of qi and blood, especially the reflectivity of absorption peaks of hemoglobin.RESULTS: The reflectivity of the same auricular acupoint during menstruation is higher than that before and after menstruation, and this trend is more obvious for the Uterus point compared with the points Gan and Neifenmi. The average reflectivity of the Uterus point during menstruation was significantly higher than that before or after menstruation (P<0.01). The D-values during and after menstruation of the Uterus point were greater than those of the points Gan and Neifenmi at 544.06 and 577.47 nm, respectively (P<0.05).CONCLUSION: The diffuse reflectance light of auricular acupoints changes as qi and blood fluctuates, and there is relative specificity among different auricular acupoints in reflecting changes of qi and blood. The Uterus point may be the most sensitive auricular acupoint in reflecting uterus function and subsequent changes of qi and blood.

Abstract: A field experiment was conducted to compare the growth and metal accumulation of Vetiveria zizanioides, Paspalum notatum, Cynodon dactylon and Imperata cylindraca var. major on the tailings, amended with 10 cm domestic refuse + complex NPK fertilizer(Treatment A), 10 cm domestic refuse(Treatment B) and complex NPK fertilizer(Treatment C) respectively, and without any amendment used as control(Treatment D). The results indicated that V. zizanioides was a typical heavy metal excluder, because the concentrations in shoots of the plants were the lowest among the four plants tested. The most of metal accumulated in V. zizanioides distributed in its root, and transportation of metal in this plant from root to shoot was restricted. Therefore, V. zizanioides was more suitable for phytostabilization of toxic mined lands than P. notatum and C. dactylon, which accumulated a relatively high level of metals in their shoots and roots. It was also found that I. cylindraca var. major accumulated lower amounts of Pb, Zn and Cu than C. dactylon and P. notatum, and could also be considered for phytostalilisaton of tailings. Although the metal(Pb, Zn and Cu) concentrations in shoots and roots of V. zizanioides were the lowest, the total amounts of heavy metals accumulated in shoots of V. zizanioides were the highest among the four tested plants due to the highest dry weight yield of it. The results indicated that V. zizanioides was the best choice among the four species used for phytoremediation(for both phytostabilization and phytoextraction) of metal contaminated soils.

Abstract: The flow and thermal fields within the infrared signature suppression(IRSS) device of a marine gas turbine exhaust system were investigated numerically. For the conjugate heat transfer within the device, an integrated solution method was adopted. The discretion equation was derived for the control volume with conjugate heat transfer at its interface, with the radiation heat flux at the interface appearing as an additional source term. The solution method of velocities at the entrance of secondary flow was presented. The numerical results agreed well with corresponding experimental data, which are the basis of the prediction of infrared radiation distribution of a marine gas turbine exhaust system.

Abstract: The distribution of microbial communities in the Menggulin (MGL) and Ba19 blocks in the Huabei Oilfield, China, were studied based on 16S rRNA gene analysis. The dominant microbes showed obvious block-specific characteristics, and the two blocks had substantially different bacterial and archaeal communities. In the moderate-temperature MGL block, the bacteria were mainly Epsilonproteobacteria and Alphaproteobacteria, and the archaea were methanogens belonging to Methanolinea, Methanothermobacter, Methanosaeta, and Methanocella. However, in the high-temperature Ba19 block, the predominant bacteria were Gammaproteobacteria, and the predominant archaea were Methanothermobacter and Methanosaeta. In spite of shared taxa in the blocks, differences among wells in the same block were obvious, especially for bacterial communities in the MGL block. Compared to the bacterial communities, the archaeal communities were much more conserved within blocks and were not affected by the variation in the bacterial communities.

Abstract: This was a retrospective study conducted from 2000 to 2007 in pediatric patients aged 18 years and younger with a diagnosis of hypertensive crisis at the ED. All patients were divided into four age groups (infants, preschool age, elementary school age, and adolescents), and two severity groups (hypertensive urgency and hypertensive emergency). BP levels, etiology, severity, and clinical manifestations were analyzed by age group and compared between the hypertensive emergency and hypertensive urgency groups.The mean systolic/diastolic BP in the hypertensive crisis patients was 161/102 mmHg. The major causes of hypertensive crisis were essential hypertension, renal disorders and endocrine/metabolic disorders. Half of all patients had a single underlying cause, and 8 had a combination of underlying causes. Headache was the most common symptom (54.5%), followed by dizziness (45.5%), nausea/vomiting (36.4%) and chest pain (29.1%). A family history of hypertension was a significant predictive factor for the older patients with hypertensive crisis. Clinical manifestations and severity showed a positive correlation with age. In contrast to diastolic BP, systolic BP showed a significant trend in the older children.Primary clinicians should pay attention to the pediatric patients who present with elevated blood pressure and related clinical hypertensive symptoms, especially headache, nausea/vomiting, and altered consciousness which may indicate that appropriate and immediate antihypertensive medications are necessary to prevent further damage.It has been demonstrated that high blood pressure (BP) contributes to the early development of cardiovascular structural and functional changes in children [1,2]. With increasingly high BP, autoregulation eventually fails, leading to damage of the vascular wall and further organ hypoperfusion. Hypertensive crisis is a critical condition characterized by a rapid, inappropriate and symptomatic elevated BP, and is categorized as hypertensiv

Abstract: To improve and simplify the NIR prediction model of the soluble solid content (SSC) of strawberry, backward interval partial least squares (BiPLS) and simulated annealing algorithm (SAA) were combined to select the efficient wavelengths. The strawberry spectra were divided into 21 intervals, among which 4 subsets, i.e. No.8, 13, 16 and 17 were selected by BiPLS. Then SAA was used to select variables in these informative regions, which were used for regression variables of MLR model. Finally, 7565 cm-1, 7706 cm-1, 8289 cm-1, 8489 cm-1, 8499 cm-1, 8724 cm-1 and 8807 cm-1 were used to build a MLR model. The MLR model performs well with root mean standard error of prediction (RMSEP) of 0.428 for SSC, which out performs models using PLS and BiPLS. This work proved that the BiPLS-SAA could determine optimal variables in NIR spectra and improve the accuracy of model.

International Journal of Molecular Sciences , 2009, DOI: 10.3390/ijms10010018
Abstract: To perform whole genome scanning for complex trait analysis, we isolated and characterized a total of 21 novel genomic-SSRs and EST-SSRs for yellow perch (Perca flavescens), using the methods of construction of SSR-enrichment libraries and EST database mining of a related species P. fluviatilis. Of 16 genomic-SSR primer pairs examined, eight successfully amplified scorable products. The number of alleles at these informative loci varied from 3 - 14 with an average of 8.5 alleles per locus. When tested on wild perch from a population in Pennsylvania, observed and expected heterozygosities ranged from 0.07 - 0.81 and from 0.37 - 0.95, respectively. Of 2,226 EST sequences examined, only 110 (4.93%) contained microsatellites and for those, 13 markers were tested, 12 of which exhibited polymorphism. Compared with genomic-SSRs, EST-SSRs exhibited a lower level of genetic variability with the number of alleles of averaging only 2.6 alleles per locus. Cross-species utility indicated that three of the genomic-SSRs and eight of the EST-SSRs successfully cross-amplified in a related species, the walleye (Sander vitreus).
Ecological effectiveness of constructed wetlands in treating oil refined wastewater

XIA Han-Ping,

生态学报 , 2003,
Abstract: Wastewater produced from the oil refinery of the Maoming Petro-Chemical Company, China Petro-Chemical Corporation contains high concentrations of organic and inorganic pollutants, therefore it cannot be discharged directly into river or sea unless being treated first. Four plant species, Vetiveria zizanioides, Phragmites australis, Typha latifolia, and Lepironia articutala were planted in large containers as constructed vertical flow wetland to test their efficiencies in the purification of oil refined wastewater and their growth in wetlands soaked with oil refined wastewater. The results gotten from a 2-month treatment indicated that the purifying rates of constructed wetlands for oil refined wastewater were all very high at the beginning, which removed 97.7% of ammonia N, 78.2% of COD, 91.4% of BOD, and 95.3% of oil in the first batch of highly-concentrated wastewater (HCW), and 97.1% of ammonia N, 71.5% of COD, 73.7% of BOD, and 89.8% of oil in the first batch of low-concentrated wastewater (LCW). But the performance of wetlands was decreased and became basically stable as time passed. The efficiency of wetlands in removing the pollutants was always in order of ammonia N > oil > BOD > COD, but the net removal of plants to them was ranked as COD > BOD > oil and ammonia N. In the beginning, the purifying function of plants was quite weak, but it gradually increased with the acceleration of plants growth. However, there was almost no significant difference in the removal efficiencies among the four species. The four tested species produced better growth in wetlands with HCW or LCW than with clean water, but V. zizanioides, P. australis, T. latifolia produced fewer tillers in HCW than those in LCW, while this was contrary to L. articutala. This inferred that HCW might damage the first three species, and promote the growth of L. articutala. During the period of clean water cultivation, the new tiller producing rate of V. zizanioides was the lowest among the four species, but it gradually rose during the period of treatment water soak, while the tiller-producing rates of the other three species were distinctly lowered. It was therefore suggested that V. zizanioides might have a stronger adaptation to the harsh environment than other species tested in the experiment, especially in the situation of long time of adaptation to the environment. However, the above results remains to be further verified due to the limited observation time of only two months.
