ABSTRACT Purpose Shen-fu injection (SFI) was used to intervene in the resuscitation of porcine hemorrhagic shock (HS) model to study its protective effects on acute kidney injury. Methods After 60 min of HS, 28 animals were randomly assigned into four groups. The groups were as follows: hemorrhagic shock group (HS); HS resuscitation with shed-blood group (HSR); HS resuscitation with shed-blood and SFI (1 mL·kg–1) group (HSR-SFI); and the sham operation group (Sham). The bloods were analyzed for serum creatinine (sCr), cystatin C (CysC) and neutrophil gelatinase-associated lipocalin (NGAL). BAX, Bcl-2, and caspase-3 protein expressions by Western blot analysis and immunohistochemical staining. The renal tissues were removed and pathologic changes were observed. Results Mean aortic pressure (MAP) in HSR-SFI groups were higher than that in HSR groups after shock. At the 6th hour after shock, the urine volume per hour in the HSR-SFI groups was more than that in the HSR groups. The sCr, NGAL, CysC and cytokine levels of HSR-SFI groups were lower. The Bcl-2 expression was increased in the HSR-SFI groups. The BAX and caspase-3 expressions were reduced. The histopathologic score in the HSR-SFI was lower. Conclusions SFI may reduce the risk of acute kidney injury (AKI) following hemorrhagic shock by attenuating systemic inflammatory responses, and regulating the expression of apoptosis-related proteins.

Fulminant type 1 diabetes mellitus (FT1DM) has received clinical attention for its low incidence and poor prognosis. Currently, few cases of FT1DM are associated with pregnancy in clinical practice, but it poses a great threat to the life of mothers and infants. Here, we present two cases of FT1DM in pregnancy. In Case 1, the patient was a 26-year-old woman who was admitted to the hospital with reduced fetal movement. She was diagnosed with FT1DM and delivered a dead female fetus. Lispro and lantus were administered to control blood glucose, and lipoic acid for antioxidant therapy. In Case 2, the patient was a 28-year-old woman who developed nausea, vomiting, diarrhea, and polydipsia, which later proved to be FT1DM. An abortion was induced and blood glucose levels were controlled using an insulin pump. All physicians should be aware of this disease in order to provide prompt diagnosis and emergency treatment, thus improving maternal prognosis. We suggest that plasma glucose/hemoglobin A1C ratio be adopted as a new clinical parameter in predicting FT1DM.

Abstract: This study targeted community members who have purchased smartphone and have joined the official brand fan pages of the smartphone brands for at least six months. A total of 681 valid samples were collected. Structural equation modeling was employed to conduct path analyses, and the results show that the 7 hypothetical paths proposed in this study are supported by the theoretical model, which exhibited desirable goodness of fit. In the mediation effect, brand passions partially mediate exogenous factors and brand loyalty. This study is aimed at increasing understanding of how a firm that possesses a cluster of fans who actively protect its brand maintain a strong brand relationship with its brand fans through brand community.

Abstract: The effect of the Internet and social media on consumer behavior has recently begun to outweigh the effect of traditional marketing strategies. Therefore, numerous enterprises have begun to use social media to communicate with brand users, and social media has b"ecome the optimal tool for brand marketing. According to current brand-community relationships from the perspectives of brand authenticity and brand identification, we identified the mediating factors (brand trust and brand passion) of relationships between community members and brands and developed an integrated model to determine the effects of these factors on community member purchase intentions. The research targets in the present study were consumers who had purchased products from one of the top three cosmetic brands in Taiwan and had been a member of the brand's oficial fan page for at least 1 year. Overall, 484 valid samples were collected in this study. We employed structural equation modeling to examine our model. Five hypotheses were supported, and excellent model fits to the data were obtained. Additionally, this study discovered that brand trust and brand passion played crucial mediating roles. Finally, we propose management implications and make suggestions that can serve as a reference for brand community managers.

Abstract Purpose: To investigate the effect of intravascular cooling on renal function after resuscitation. Methods: Twenty four pigs were randomized into three groups (n=8 in each group): therapeutic hypothermia group (TH group), normothermia group (NH group) and sham operation group (SHAM group). After 6 minutes of untreated VF, CPR was performed. Upon ROSC, the TH group received the intravascular cooling. The NH and SHAM group did not undergo therapeutic hypothermia. Haemodynamic parameters were recorded. The bloods were analyzed for serum creatinine (sCr), CysC and NGAL. The kidney was surgically removed observe pathologic changes under a light microscope. Results: The sCr increased in both TH and NH groups after ROSC, compared to baseline. Between two groups, the sCr and creatinine clearance (Cc) showed lower level in the TH group. The urine volume per hour in the TH group were higher during cooling. After resuscitation, NGAL and CysC in the NH group were higher than in the TH group. Under the light microscope, compared with the TH group, the renal injury was prominent in the NH group. Conclusion: Mild hypothermia had a protection to renal ischemia reperfusion injury after resuscitation.

Abstract The viability of Lactobacillus bulgaricus in freeze-drying is of significant commercial interest to dairy industries. In the study, L.bulgaricus demonstrated a significantly improved (p < 0.05) survival rate during freeze-drying when subjected to a pre-stressed period under the conditions of 2% (w/v) NaCl for 2 h in the late growth phase. The main energy source for the life activity of lactic acid bacteria is related to the glycolytic pathway. To investigate the phenomenon of this stress-related viability improvement in L. bulgaricus, the activities and corresponding genes of key enzymes in glycolysis during 2% NaCl stress were studied. NaCl stress significantly enhanced (p < 0.05) glucose utilization. The activities of glycolytic enzymes (phosphofructokinase, pyruvate kinase, and lactate dehydrogenase) decreased during freeze-drying, and NaCl stress were found to improve activities of these enzymes before and after freeze-drying. However, a transcriptional analysis of the corresponding genes suggested that the effect of NaCl stress on the expression of the pfk2 gene was not obvious. The increased survival of freeze-dried cells of L. bulgaricus under NaCl stress might be due to changes in only the activity or translation level of these enzymes in different environmental conditions but have no relation to their mRNA transcription level.

Crop growth in a saline environment depends on its tolerance to salt stress and capacity to recover after salt stress relief. To evalúate recovery mechanisms in cotton after salt stress relief, the changes of plants growth, root vigor, lipid peroxidation, antioxidant enzymes activity, organic solutes in root after salt stress relief were studied for two cotton (Gossypium hirsutum L.) cultivars (Lumianyan 37 and Sumian 22) grown under control (salt content of soil grown cotton was maintained at 0.2%), salt stressed (salt content of soil grown cotton was maintained at 0.5%) and salt recovered (salt content of soil grown cotton was reduced from 0.5% to 0.2% level at the 57 d after seeding) conditions. The results showed that root and shoot growth rate and root vigor significantly increased after salt stress relief, and the increase in growth rate and root vigor was more pronounced in ’Lumianyan 37’. In salt-recovered root, malondialdehyde (MDA) content decrease, the activities of superoxide dismutase (SOD) and peroxidase (POD) decreased, but catalase (CAT) activity increased compared with those in the salt-stressed root. For salt-recovered root, MDA content and POD activity of ’Lumianyan 37’ was lower, while the SOD and CAT activities were higher. Salt-recovered cotton root showed a decrease in soluble sugar and free amino acid content compared with the salt-stressed root, especially in ’Lumianyan 37’. The results indicated that growth and root metabolism of cotton plants gradually recovered after salt stress relief, and the high capacity of cotton plants to recover after salt stress relief may be related to the high capacity of antioxidative system and the high utilization capacity of organic solutes as important nutritional components in root.

The plant growth-promoting rhizobacterial strain Pseudomonas putida Rs-198 was isolated from salinized soils from Xinjiang Province. We optimized the composition of the low-cost medium of P. putida Rs-198 based on its bacterial concentration, as well as its phosphate-dissolving and indole acetic acid (IAA)-producing capabilities using the response surface methodology (RSM), and a mathematical model was developed to show the effect of each medium component and its interactions on phosphate dissolution and IAA production. The model predicted a maximum phosphate concentration in medium containing 63.23 mg/L inorganic phosphate with 49.22 g/L corn flour, 14.63 g/L soybean meal, 2.03 g/L K2HPO4, 0.19 g/L MnSO4 and 5.00 g/L NaCl. The maximum IAA concentration (18.73 mg/L) was predicted in medium containing 52.41 g/L corn flour, 15.82 g/L soybean meal, 2.40 g/L K2HPO4, 0.17 g/L MnSO4 and 5.00 g/L NaCl. These predicted values were also verified through experiments, with a cell density of 10(13) cfu/mL, phosphate dissolution of 64.33 mg/L, and IAA concentration of 18.08 mg/L. The excellent correlation between predicted and measured values of each model justifies the validity of both the response models. The study aims to provide a basis for industrialized fermentation using P. putida Rs-198.

Background Peanut (Arachis hypogaea L.) is an important economic and oilseed crop. Long-term rainless conditions and seasonal droughts can limit peanut yields and were conducive to preharvest aflatoxin contamination. To elucidate the molecular mechanisms by which peanut responds and adapts to water limited conditions, we isolated and characterized several drought-induced genes from peanut roots using a suppression subtractive hybridization (SSH) technique. Results RNA was extracted from peanut roots subjected to a water stress treatment (45% field capacity) and from control plants (75% field capacity), and used to generate an SSH cDNA library. A total of 111 non-redundant sequences were obtained, with 80 unique transcripts showing homology to known genes and 31 clones with no similarity to either hypothetical or known proteins. GO and KEGG analyses of these differentially expressed ESTs indicated that drought-related responses in peanut could mainly be attributed to genes involved in cellular structure and metabolism. In addition, we examined the expression patterns of seven differentially expressed candidate genes using real-time reverse transcription-PCR (qRT-PCR) and confirmed that all were up-regulated in roots in response to drought stress, but to differing extents. Conclusions We successfully constructed an SSH cDNA library in peanut roots and identified several drought-related genes. Our results serve as a foundation for future studies into the elucidation of the drought stress response mechanisms of peanut.

PURPOSE: To systematically evaluate the clinical efficacy of reamed and nonreamed intramedullary nailing in treatment of closed tibial fractures with Cochrane systematic review methods. METHODS: According to the Cochrane systematic review methods, literatures were retrieved from Cochrane library, PubMed, EMbase and other database. Randomized controlled trials (RCTs) and quasi-randomized controlled clinical trials about reamed and nonreamed intramedullary nailing in the treatment of closed tibial fractures were collected and RevMan 5.0 was chosen for meta-analysis. RESULTS: A total of seven studies were included in this meta-analysis. Reamed intramedullary nailing was better than nonreamed intramedullary nailing in nonunion rate [P = 0.02, RR = 0.46, 95% CI: (0.24, 0.91)] and implant failure rate [P <0.0001, RR = 0.36, 95% CI: (0.22, 0.57)]. No statistically significant difference was observed in malunion rate, compartment syndrome rate, postoperative infection [P = 0.18, RR = 0.50, 95% CI: (0.18, 1.383); P = 0 43, RR = 0.77, 95% CI: (0.40, 1.48); P = 0.27, RR = 0.38, 95% CI: (0.01, 7.87)]. CONCLUSION: Compared with the nonreamed intramedullary nailing, reamed intramedullary nailing can lead to better outcome in the treatment of closed tibial fractures.

Background: Based on the conserved sequences of a known NBS resistance gene, a pair of degenerate primers was designed to amplify the NBS-LRR resistance gene from peanut using PCR and RACE methods. Results: Analyzing the amino acid sequence by BLAST on NCBI, which was deduced from the 1088bp-long gene named PnAG1-2, showed that it had a certain homology with some resistance proteins, among which Arachis cardenasii resistance protein gene had the highest homology (66%). Relative quantification PCR analysis indicated that PnAG1-2 gene expresses more in J11 (an A. flavus-resistant variety) than in JH1012 (an A. flavus-susceptible variety) when the harvest time was coming. Conclusions: In this study, the NBS-LRR resistance sequence was successfully cloned from peanut and prokaryotic expression was done on the gene, which provided a foundation for cultivating anti-A. flavus peanut varieties.

We have developed analytical methods to measure the biological functions of pVGI.1(VEGF2), a naked plasmid DNA product containing vascular endothelial growth factor 2 used in clinical trials for coronary artery diseases (CAD) and peripheral artery diseases (PAD). After being injected into muscles, vascular endothelial growth factor 2 (VEGF-2), presumably expressed in muscle tissues, binds to the endothelial cell receptors VEGFR2 or VEGFR3, triggering the downstream responses including cell proliferation and vascularization. As it is important to make sure clinical material is biological active, we developed a quantitative assay first to measure the receptor binding activity of the pVGI.1(VEGF2) gene product expressed by the transfected host cells, and then a qualitative assay to confirm the cell proliferation promoting activity of the expressed protein. In both assays the signals were plotted directly against input DNA concentrations used to transfect the host cells. We confirmed specificity for both assays. In addition, we demonstrated acceptable levels of spike recovery (86.7-116%), precision (largest relative standard deviation (RSD)=19.3%), linearity and range (60-140% relative potency, 15 - 35 µg/mL) for the quantitative assay. We intend to use the potency assays for routine lot release and stability studies.
