Aesthetic evaluation of plant landscape based on principal factor analysis and SBE in wetland park – a case study of Jinlong lake wetland park (China)

The aesthetic value of 35 plant landscape samples of Jinlong lake wetland park in Xuzhou city of China were evaluated with principal factor analysis and SBE method. The results showed that: The SBE value of 35 plant landscape samples fluctuated greatly and the evaluation value of the principal factor did not change much. The order of SBE mean values of different types was: plant landscape on both sides of the roads > plant landscape beside buildings and surroundings > typical plant community > waterfront plant landscape. The order of value of the principal factor analysis of different types was: plant landscape on both sides of the roads > typical plant community > plant landscape beside buildings and surroundings > waterfront plant landscape. The principal factor evaluation method contained more than 90% information of seven evaluation factors, while the SBE method mainly evaluated from “plant aesthetic factors”. The satisfaction of waterfront plant landscape was low, the transformation of plant landscape should focus on increasing the species of waterfront plants, especially native plants, building natural revetments, creating rich canopy lines

The Effects of miR-136-5p-Mediated Regulation of A20 in Astrocytes from Cultured Spinal Cord Cultured Cells In Vitro

Background/Aims: This study focused on investigating the regulatory mechanism of miR-136-5p in mouse astrocytes stimulated with interleukin-17(IL-17). Methods: C57BL/6 mouse astrocytes were stimulated with IL-17 (100ng/ml) for various periods of time (0-48 hours) and at various doses (0-200 ng), and the expression levels of inflammatory cytokine and chemokine genes (IL-6, TNF-α, MCP-1, MCP-5 and MIP-2) were then detected by real-time PCR. The expression of the A20 gene was measured with real-time PCR in cells that were stimulated with IL-17 (50 ng/ml) for various periods of time (0-48 hours). C57BL/6 mouse astrocytes were transfected with Ctrl-anti-miR-136-5p or LNA -anti-miR-136-5p for 48 h. Thereafter, the cells were stimulated with or without IL-17 (50ng/ml) for 6 h. The level of A20 protein (TNFα-induced protein 3, TNFAIP3) was detected by Western blot analysis. Results: (1) Compared with the DMEM control group, within six hours, IL-17 stimulation significantly increased the expression levels of inflammatory cytokine and chemokine genes and clearly decreased the expression level of the A20 protein. (2) Without IL-17 stimulation, the expression level of the miR-136-5p gene was significantly decreased, whereas in the miR-136-5p-inhibition group, the A20 protein expression was elevated. IL-17 stimulation slightly decreased the expression of the A20 protein in the miR-136-5p-inhibition group, but it was still slightly higher than in the control group. Conclusion: This study demonstrated that miR-136-5p affected the expression of A20 in IL-17-stimulated astrocytes

Association of admission serum calcium levels and in-hospital mortality in patients with acute ST-elevated myocardial infarction: an eight-year, single-center study in China.

OBJECTIVE: The relationship between admission serum calcium levels and in-hospital mortality in patients with acute ST-segment elevation myocardial infarction (STEMI) has not been well definitively explored. The objective was to assess the predictive value of serum calcium levels on in-hospital mortality in STEMI patients. METHODS: From 2003 to 2010, 1431 consecutive STEMI patients admitted to the First Affiliated Hospital of Nanjing Medical University were enrolled in the present study. Patients were stratified according to quartiles of serum calcium from the blood samples collected in the emergency room after admission. Between the aforementioned groups,the baseline characteristics, in-hospital management, and in-hospital mortality were analyzed. The association of serum calcium level with in-hospital mortality was calculated by a multivariable Cox regression analysis. RESULTS: Among 1431 included patients, 79% were male and the median age was 65 years (range, 55-74). Patients in the lower quartiles of serum calcium, as compared to the upper quartiles of serum calcium, were older, had more cardiovascular risk factors, lower rate of emergency revascularization,and higher in-hospital mortality. According to univariate Cox proportional analysis, patients with lower serum calcium level (hazard ratio 0.267, 95% confidence interval 0.164-0.433, p<0.001) was associated with higher in-hospital mortality. The result of multivariable Cox proportional hazard regression analyses showed that the Killip's class≥3 (HR = 2.192, p = 0.026), aspartate aminotransferase (HR = 1.001, p<0.001), neutrophil count (HR = 1.123, p<0.001), serum calcium level (HR = 0.255, p = 0.001), and emergency revascularization (HR = 0.122, p<0.001) were significantly and independently associated with in-hospital mortality in STEMI patients. CONCLUSIONS: Serum calcium was an independent predictor for in-hospital mortality in patients with STEMI. This widely available serum biochemical index may be incorporated into the current established risk stratification model of STEMI patients. Further studies are required to determine the actual mechanism and whether patients with hypocalcaemia could benefit from calcium supplement

RETRACTED: Forensic characteristics and phylogenetic analyses of one branch of Tai‐Kadai language‐speaking Hainan Hlai (Ha Hlai) via 23 autosomal STRs included in the Huaxia™ Platinum System

Abstract Background Hainan Island, located in the South China Sea and separated from the Leizhou Peninsula by Qiongzhou Strait, is the second largest island after Taiwan in China. With the expansion of Han Chinese and the gradual formation of “South Hlai and North Han”, nowadays, Hainan Hlai is the second largest population after Han Chinese in Hainan Island. Ha Hlai, distributed in southwest and southern Hainan Island, is the dominant branch of Hlai and speaks Ha localism. Methods We utilized the Huaxia™ Platinum PCR Amplification System (including 23 autosomal STRs and 2 sex‐linked markers) to obtain the first STR profiling batch of 657 Ha Hlai individuals (497 males and 160 females). In order to explore the genetic relationships between the studied Ha Hlai and other reference populations with different language families, population genetic analyses, including PCA, MDS, STRUCTURE, and phylogenetic analysis, were conducted based upon the raw data and allelic frequencies of the polymorphic autosomal STR markers. Results In total, 271 distinct alleles were observed at the 23 STR loci. The number of diverse alleles ranged from 7 at TPOX locus to 23 at FGA locus, and the allelic frequencies varied from 0.0008 to 0.5533. In addition, the CPE and CPD were 1‐7.39 × 10−10 and 1‐3.13 × 10−28, respectively. The phylogenetic analyses indicated that Ha Hlai is a Tai‐Kadai language‐speaking and relatively isolated population which has a close genetic and geographical relationship with Hainan Hlai, and M95 is the dominant haplogroup in Ha Hlai (56.18%). Conclusion The 23 autosomal STR genetic markers were highly polymorphic as well as potentially useful for forensic applications in Hainan Ha Hlai population. The phylogenetic analyses demonstrated that small geographic scale gene flows could not be ignored and the shaping of the unique gene pool for each population was the combination effects of geographic, language, and cultural isolations
