Zhong Xi Yi Jie He Xue Bao , 2012,
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.

Umbilical Cord-Derived Mesenchymal Stem Cells for Hematopoietic Stem Cell Transplantation
Yu-Hua Chao,Han-Ping Wu,Chin-Kan Chan,Chris Tsai,Ching-Tien Peng,Kang-Hsi Wu
Journal of Biomedicine and Biotechnology , 2012, DOI: 10.1155/2012/759503
Abstract: Hematopoietic stem cell transplantation (HSCT) is becoming an effective therapeutic modality for a variety of diseases. Mesenchymal stem cells (MSCs) can be used to enhance hematopoietic engraftment, accelerate lymphocyte recovery, reduce the risk of graft failure, prevent and treat graft-versus-host disease, and repair tissue damage in patients receiving HSCT. Till now, most MSCs for human clinical application have been derived from bone marrow. However, acquiring bone-marrow-derived MSCs involves an invasive procedure. Umbilical cord is rich with MSCs. Compared to bone-marrow-derived MSCs, umbilical cord-derived MSCs (UCMSCs) are easier to obtain without harm to the donor and can proliferate faster. No severe adverse effects were noted in our previous clinical application of UCMSCs in HSCT. Accordingly, application of UCMSCs in humans appears to be feasible and safe. Further studies are warranted.

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: 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: A method based on Logistic map to generate poly-phase (2 n phases) sequence proposed in this paper. It gives the sufficient condition for this map to produce an independent and identically distributed (i.i.d) poly-phase pseudorandom (PN) sequence. The theoretical and numerical analyses show that the sequence also has a high complexity. It gives a fast algorithm to generate this sequence and general expression of the sequence in the paper too. The sequence can be used in fields such as information security and spread spectrum communication.

Abstract: The infrared transmission of ground object and its background were discussed. A new passive distance measuring method was deduced based on the irradiance errors between the ground object and its background detected. By the above-mentioned new method, the formula of distance measuring and the formula of distance resolving power were formed. The relationship between the irradiance errors and the distance, and the relationship between the distances resolving power and the distance under different weather conditions were calculated. The calculation result has proved that the method can be applied to the distance measurement of ground objects.

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.

Abstract: Objective To analyze whether urine output and urinalysis results are predictive of survival and neurologic outcomes in patients with non-traumatic out-of-hospital cardiac arrest (OHCA). Methods Information was obtained from 1,340 patients with non-traumatic OHCA who had achieved a sustained return of spontaneous circulation (ROSC). Factors that were associated with survival in the post-resuscitative period were evaluated. The association between urine output and fluid challenge in the early resuscitative period was analyzed and compared between the survivors and the non-survivors. The results of the initial urinalysis, including the presence of proteinuria and other findings, were used to evaluate the severity of vascular protein leakage and survival. The association between proteinuria and the neurologic outcomes of the survivors was also analyzed. The clinical features of capillary leakage were examined during the post-resuscitative period. Results Of the 1,340 patients, 312 survived. A greater urine output was associated with a higher chance of survival. The initial urine output increased in proportion to the amount of fluid that was administered during early resuscitation in the emergency department for the survivors but not for the non-survivors (p<0.05). In the initial urinalysis, proteinuria was strongly associated with survival, and severe proteinuria indicated significantly poorer neurologic outcomes (p<0.05 for both comparisons). Proteinuria was associated with a risk of developing signs of capillary leakage, including body mass index gain and pitting edema (both p<0.001). Conclusion The severity of proteinuria during the early post-resuscitative period was predictive of survival.
