Abstract
OBJECTIVE To analyze the relationship between risk factors and prognosis of acute organophosphorus pesticide poisoning (AOPP). METHODS The clinical data including APACHEⅡ, D-dimer, C-reactive protein, procalcitonin, lactic acid of the 67 cases of acute organophosphorus pesticide poisoning which respectively divided into survival group and death group by the outcome were collected. The independent influcing factors were got by logistic regression analysis. RESULTS The analysis showed that APACHEⅡ, D-dimer、C-reactive protein and Procalcitonin were influencing factors to evaluate prognosis of AOPP (P<0.05) .Meanwhile, APACHEⅡ and CRP were the independent influencing factors to evaluate prognosis of AOPP (P<0.05). APACHEⅡ26was the optimum thresholds to acess the prognosis of AOPP and its Youden index was largest. CONCLUSION APACHEⅡ and CRP played an important role in the assessment of prognosis on AOPP. When APACHEⅡwas more than 26, it suggested the patient of AOPP will have a bad prognosis.

Abstract
Soluble starch synthase (SS) is one of the key enzymes involved in amylopectin biosynthesis in plants. However, no information is currently available about this gene family in the important fruit crop banana. Herein, we characterized the function of MaSSIII-1 in amylopectin metabolism of banana fruit and described the putative role of the other MaSS family members. Firstly, starch granules, starch and amylopectin content were found to increase during banana fruit development, but decline during storage. The SS activity started to increase later than amylopectin and starch content. Secondly, four putative SS genes were cloned and characterized from banana fruit. Among them, MaSSIII-1 showed the highest expression in banana pulp during fruit development at transcriptional levels. Further Western blot analysis suggested that the protein was gradually increased during banana fruit development, but drastically reduced during storage. This expression pattern was highly consistent with changes in starch granules, amylopectin content, and SS activity at the late phase of banana fruit development. Lastly, overexpression of MaSSIII-1 in tomato plants distinctly changed the morphology of starch granules and significantly increased the total starch accumulation, amylopectin content, and SS activity at mature-green stage in comparison to wild-type. The findings demonstrated that MaSSIII-1 is a key gene expressed in banana fruit and responsible for the active amylopectin biosynthesis, this is the first report in a fresh fruit species. Such a finding may enable the development of molecular markers for banana breeding and genetic improvement of nutritional value and functional properties of banana fruit.

Abstract
Our previous work revealed that in the pancreatic β cell line, geniposide modulated ATP production and glucose-stimulated insulin secretion (GSIS) induced by the acute stimulation of high glucose concentration. However, the effects of geniposide on functional impairment and the mass of β-cells exposed to elevated levels of glucose remains unknown. In the present study, impaired GSIS and restrained proliferation were observed in the prolonged culture of insulinoma INS-1 cells with 33mM of glucose (high glucose). Our results indicate that the glucose-induced impairment of insulin release was significantly reverted by the inclusion of 1 or 10μM of geniposide. Moreover, induction of the phosphorylation of AMP-activated protein kinase (AMPK) was observed, which promoted the utilization of nutrient stores for energy production. AMPK phosphorylation was enhanced by an increased number of INS-1 cells, and the increased expression of AMPK downstream target heme oxygenase 1 (HO-1), under high glucose concentration. Furthermore, geniposide protected rat insulinoma cells from apoptosis in high-glucose concentrations. We have shown that these effects were associated with an increased apoptosis-related Bcl-2/BAX protein ratio. In conclusion, geniposide dose dependently improves β-cell function and increases the proliferation of β-cells exposed to prolonged hyperglycemia.

Abstract
The growth, development, and production of banana plants are constrained by multiple abiotic stressors. However, it remains elusive for the tolerance mechanisms of banana responding to multiple abiotic stresses. In this study, we found that Fen Jiao (FJ) was more tolerant to osmotic, cold, and salt stresses than BaXi Jiao (BX) by phenotypic and physiological analyses. Comparative transcriptomic analyses highlighted stress tolerance genes that either specifically regulated in FJ or changed more than twofold in FJ relative to BX after treatments. In total, 933, 1644, and 133 stress tolerance genes were identified after osmotic, cold, and salt treatments, respectively. Further integrated analyses found that 30 tolerance genes, including transcription factor, heat shock protein, and E3 ubiquitin protein ligase, could be commonly regulated by osmotic, cold, and salt stresses. Finally, ABA and ROS signaling networks were found to be more active in FJ than in BX under osmotic, cold, and salt treatments, which may contribute to the strong stress tolerances of FJ. Together, this study provides new insights into the tolerance mechanism of banana responding to multiple stresses, thus leading to potential applications in the genetic improvement of multiple abiotic stress tolerances in banana.

Abstract
OBJECTIVE To discuss the suitability of frailty index for comprehensive geriatric assessment(FI-CGA)in the elderly in China, and evaluate the application of FI-CGA in China. METHODS A comprehensive geriatric assessment was conducted among 118 old adults receiving health examination, and frailty index was calculated. Clinical frailty scale(CFS)was also used to evaluate the frail status of the old adults. The correlation between FI-CGA value and CFS level of the old adults was analyzed. RESULTS The mean value of FI-CGA was 0.19 ± 0.07, and the average level of CFS was 3.11 ± 1.46. Women had higher mean value of FI-CGA and higher CFS level than men(FI-CGA= 0.20 ± 0.02 for women, 0.19 ± 0.07 for men; CFS =3.40 ± 0.55 for women, 3.10 ± 1.48 for men), but the differences had no significance(t=0.270, 0.452, P=0.788, 0.652). The FI-CGA value and CFS level increased with age(F=10.437, 5.651, P=0.000, 0.001); and there was a positive correlation between FI-CGA value and CFS level(r=0.615, P=0.000). CONCLUSION FI-CGA is an effective model for the quantitative evaluation of the frail status of the elderly, and can be used in the clinical practice of geriatric medicine.

Abstract
Objective: To investigate the injury and pathological changes of kidney in a rat model of aortic vascular calcification and to explore the expressions of fibroblast growth factor 21 (FGF21). Methods: A total of 14 Spraugue Dawley (SD) rats were randomly divided into two groups: control group and vitamin D3+ nicotine (VDN) group, with 7 rats in each group.The rats in VDN group received vitamin D3 and nicotine to induce vascular calcification.The content of serum creatinine was determined by sarcosine oxidase method.Alkaline phosphatases (ALP) activity was detected by ALP detection kit.The protein levels of FGF21 were measured by radioimmunoassay (RIA). The structure of kidney was observed by hematoxylin and eosin staining. Results: The serum concentration of creatinine in VDN group was significantly higher than control group[(34.00±4.69) vs (27.17±5.38) μmol/L, P<0.05], and the renal pathological changes in VDN group were more apparent. ALP activity in VDN group was significantly higher than that in control group[(62.59±22.62) vs (29.89±11.78) U/g, P<0.05]. Expression of FGF21 in VDN group increased obviously, compared with that in control group[(0.583±0.340) vs (0.207±0.105) ng/mg, P<0.05]. Meanwhile, the elevated levels of FGF21 were positively correlated with up-regulation of ALP in calcified kidneys (r=0.878, P<0.05). Conclusions: Flushing dose of vitamin D3 and nicotine can induce the change of pathology and function of the kidney.Meanwhile, the expression of FGF21 in kidney up-regulated significantly, suggesting that FGF21 may be involved in the occurrence and development of vascular calcification and subsequent kidney injury.

Abstract
The flexible hybrid transparent electrode was prepared by a two-step process: graphene film was firstly grown on Cu foil by modified thermal chemical vapor deposition (CVD) and then transferred onto indium tin oxide (ITO) electrode on the polyethylene terephthalate (PET) substrate. The quality of the graphene is characterized by various analytic techniques, including the AFM, SEM, TEM, and Raman spectroscopy. The gradient flux was found to be beneficial to decrease defect. The thickness, morphology, light transmittance, and electromechanical properties of three conductive electrodes were investigated and compared. The outcomes show that the hybrid electrode could resist mechanical force and the results are better than original ITO electrode. It may be a potential trend to apply the graphene to other conducts in the flexible transparent conductive field.

Abstract
Objective: To evaluate the value of single-source dual-energy CT (ssDECT) in differentiating lipid-poor adenomas from metastases in adrenal glands. Methods: From August 2011 to Oct 2014, 63 patients with 73 adrenal nodules (53 metastases proven by 5-6 months follow-up, and 20 histopathologically proven adenomas, CT value > 10 HU) underwent ssDECT scanning. The CT values of conventional polychromatic CT and virtual monochromatic images (40-140 keV) , fat-water density images and effective atomic number (eff-Z) were reconstructed on an ADW4.5 workstation and ROC curves were then constructed to evaluate the effectiveness of each parameter. The slope of spectral curve was measured and divided into 3 types: increment curve (K>0.1), straight curve (-0.1≤K≤0.1) and decrement curve (K< -0.1) according to the slope (the value of K) of spectral curve, and the curve patterns in the two groups were compared statistically. Results: There was no statistical difference between the mean CT values of metastases (35.12±5.29)HU and lipid-poor adenomas (32.48±6.94)HU by conventional polychromatic CT (P>0.05). The range of single-energy CT values of metastases [from (53.00±15.12) HU to (33.38±5.67) HU] was significantly higher than that of lipid-poor adenomas [from (26.90±26.94) HU to (28.77±10.66) HU] at energy levels ranging from 40 to 80 keV (P<0.05). There was no significant difference between the single-energy CT value of metastases and lipid-poor adenomas at energy levels ranging from 90 to 140 keV (P>0.05). The median fat-water concentration of metastases was -164.61 μg/cm3, significantly lower than that of lipid-poor adenomas (114.32 μg/cm3,P<0.05). The eff-Z of metastases (7.76±0.15) was also significantly higher than that of lipid-poor adenomas (7.50±0.25, P<0.05). When the threshold of fat-water concentration was -143.89 μg/cm3, the sensitivity, specificity and accuracy rate of metastasis diagnosis was 70.0%, 66.0%, and 76.7%, respectively. When the threshold of eff-Z was 7.63, the sensitivity, specificity and accuracy rate of metastasis diagnosis was 83.0%, 65.0%, and 80.4%, respectively. The lower the energy, the higher the diagnostic accuracy at energy levels ranging from 40 to 80 keV, and that of 40 keV was the highest. The spectral curves of metastases included 2 (3.8%) ascending curves, 9 (17.0%) straight curves and 42 (79.2%) descending curves, while in the 20 lipid-poor adenomas, there were 9 (45.0%) ascending curves, 4 (20.0%) straight curves and 7 (35.0%) descending curves, showing significant differences between the two groups (P<0.05). Conclusions: Single-source dual-energy CT provides an effective multi-parameter approach for differentiating lipid-poor adrenal adenomas from metastases.

Abstract
The abscisic acid (ABA)-, stress-, and ripening-induced (ASR) protein is a plant-specific hydrophilic transcriptional factor involved in fruit ripening and the abiotic stress response. To date, there have been no studies on the role of ASR genes in delayed flowering time. Here, we found that the ASR from banana, designated as MaASR, was preferentially expressed in the banana female flowers from the eighth, fourth, and first cluster of the inflorescence. MaASR transgenic lines (L14 and L38) had a clear delayed-flowering phenotype. The number of rosette leaves, sepals, and pedicel trichomes in L14 and L38 was greater than in the wild type (WT) under long day (LD) conditions. The period of buds, mid-flowers, and full bloom of L14 and L38 appeared later than the WT. cDNA microarray and quantitative real-time PCR (qRT-PCR) analyses revealed that overexpression of MaASR delays flowering through reduced expression of several genes, including photoperiod pathway genes, vernalization pathway genes, gibberellic acid pathway genes, and floral integrator genes, under short days (SD) for 28 d (from vegetative to reproductive transition stage); however, the expression of the autonomous pathway genes was not affected. This study provides the first evidence of a role for ASR genes in delayed flowering time in plants.

Abstract
The leucine zipper (bZIP) transcription factors play important roles in multiple biological processes. However, less information is available regarding the bZIP family in the important fruit crop banana. In this study, 121 bZIP transcription factor genes were identified in the banana genome. Phylogenetic analysis showed that MabZIPs were classified into 11 subfamilies. The majority of MabZIP genes in the same subfamily shared similar gene structures and conserved motifs. The comprehensive transcriptome analysis of two banana genotypes revealed the differential expression patterns of MabZIP genes in different organs, in various stages of fruit development and ripening, and in responses to abiotic stresses, including drought, cold, and salt. Interaction networks and co-expression assays showed that group A MabZIP-mediated networks participated in various stress signaling, which was strongly activated in Musa ABB Pisang Awak. This study provided new insights into the complicated transcriptional control of MabZIP genes and provided robust tissue-specific, development-dependent, and abiotic stress-responsive candidate MabZIP genes for potential applications in the genetic improvement of banana cultivars.

Abstract
OBJECTIVE To investigate the expression of RhoA/Rho-kinase (ROCK) in penile corpus cavernosum smooth muscles in rats of hyperlipidemia-induced erectile dysfunction and its molecular mechanism. METHODS Forty male Sprague-Dawley rats were randomly divided into control and experimental groups using a random number table. Rats in the control group (n=20) were fed with regular diet for 24 weeks and those in the experimental group (n=20) with high-fat diet for the same period of time. The serum lipids profile was detected before and after the diet treatment. The ratio of intracavernosal pressure (ΔICP)/mean arterial pressure (MAP) was measured, and Western blot was used to detect the expression of total RhoA, ROCK1, and ROCK2 in penile corpus cavernosum smooth muscles, and RhoA protein in cell membrane and cytoplasm of smooth muscles after 24 weeks. RESULTS After 24 weeks, the levels of cholesterol, triglyceride, and low-density lipoprotein were significantly higher in the experimental group compared with those before diet treatment and the control group (all P<0.01). ΔICP/MAP in the experimental group was greatly lower than in the control group (P<0.01). The protein expression of ROCK2 in penile corpus cavernosum smooth muscles was higher in the experimental group than in the control group (0.77±0.10 vs 0.27±0.08, P<0.01) after 24 weeks, while no statistically significant differences were observed in total RhoA and ROCK 1 protein expression between the two groups (both P>0.05). RhoA expression in cytoplasm was lower in the experimental than in the control group (1.66±0.09 vs 1.79±0.15, P<0.05). The ratio of RhoA expression in menmbrane/cytoplasm was higher in the experimental than in the control group (0.33±0.09 vs 0.26±0.07, P<0.05). CONCLUSION Up-regulation of RhoA/ROCK may be involved in hyperlipidemia-induced erectile dysfunction in rats.

Abstract
OBJECTIVE To summarize the otoscopy, CT and MRI features of spontaneous herniation of the temporomandibular joint(TMJ) into the external auditory canal(EAC) through the persistence Huschke's foramen(PHF). METHODS The otoscopy, CT and MRI images of three cases with the herniation of the TMJ into the EAC through the PHF were analyzed retrospectively. RESULTS Otoscopy revealed the masses located in the antero-inferior aspect of the bony EAC, and the mass displayed an alternative of forward and backward motion during opening and closing of the mouth.CT of the temporal bone showed a bony defect and a consecutive soft mass in the antero-inferior wall of the bony EAC. The margin of the bony defects were well-defined in all cases, the bone adjacent to PHF was pressed and partially wrapped around the soft mass as 'holding ball' in two cases, partly peripheral pseudo bony shell of the soft mass were showed in two cases. The soft mass in EAC appeared equal attenuated with the soft tissue of TMJ, and on enhanced CT scans showed no enhancement of the soft mass. On MRI scans, the imaging displayed a bony defect in the antero-inferior wall of the EAC with a soft mass which was formed by the capsule of the TMJ, and the mass showed iso-signal to the capsule of the TMJ on all sequences, and there was no enhancement after contrast administration. CONCLUSION The otoscopy, CT and MRI features of the spontaneous herniation of the TMJ into the EAC through the PHF is special, and the above examinations are valuable for diagnosis of the disease.

Abstract
In single-stage laryngotracheal reconstruction (ss-LTR), the endotracheal tube is used as a stent. The optimal duration of stenting is not known. The stenting period requires a stay in the intensive care unit, as the patient is intubated. Sedation and, rarely, paralysis may be required. An analysis from a prospectively collected database was performed to investigate the effect of length of stenting on the outcome of ss-LTR. The outcomes used were reintubation rate and postoperative tracheostomy rate. Patients with anterior costal graft ss-LTR were selected, as they had undergone similar procedures and have similar stenosis types and grades. In 101 patients, the duration of stenting ranged from 2 to 14 days (mean, 7 days; SD, 2.6 days). No significant correlation was found between the number of days stented and the reintubation rate or the postoperative tracheostomy rate. Patients stented for longer than 1 week were an average of 15 months younger than those stented for less than 1 week; however, the stenosis grades for the two populations were equivalent. The differences in rates of reintubation (p = .68) and postoperative tracheostomy (p = .52) in these 2 groups were not significant. For patients undergoing ss-LTR with anterior costal cartilage grafts, no correlation was found between the number of days stented (intubated) and the reintubation rate or the postoperative tracheostomy rate.

Abstract
OBJECTIVES To investigate the population genetic polymorphisms of 24 Y-STR loci in unrelated individuals in Eastern Chinese Han population, and to compare the difference of Han group between Eastern China and Guangdong. METHODS The population genetics of 24 Y-STR loci in 268 unrelated Han individuals from Eastern China were analyzed by GFS 24 Y-STR amplification kit. The allele frequencies in Eastern Chinese Han population were compared with the data in Guangdong Han population, and the difference analysis between two groups was performed. RESULTS Among the 24 Y-STR loci of 268 unrelated Han individuals from Eastern China, 235 alleles and 267 haplotypes were observed. GD value ranged from 0.564 9 to 0.966 8. The difference between 12 loci (DYS622, DYS552, DYS443, et al.) of Han population in Eastern China and in Guangdong was statistically significance. CONCLUSIONS GFS 24Y STR amplification system shows favorable polymorphisms, which can be used in patrilineal genetic relationship identification.

Abstract
OBJECTIVE To investigate the correlation between R2(*) value of enhanced T2 star-weighted angiography (ESWAN) sequence and primary hepatocellular carcinoma infiltration and tumor thrombus, and investigate the biological behavior of HCC. METHODS A total of 221 cases of patients' imaging data with MRI examination(including ESWAN sequence) diagnosed as primary HCC were retrospectively analyzed.All the patients were collected from January 2014 to September 2015 in the First Affiliated Hospital of Dalian Medical University.The differences of R2(*) values in different MR types of HCC were analyzed.All patients were divided into infiltration group and non-infiltration group, tumor thrombus group and non-tumor thrombus group, the R2(*) values of the paired groups were compared.The diagnostic efficiency of R2(*) in HCC infiltration and tumor thrombus were evaluated by ROC curve, and to find out the threshold values. RESULTS The MR types of 221 patients included 90 cases of nodular type, 62 cases of massive type, 69 cases of diffuse type.70 patients had tumor thrombus.The R2(*) values of different MR types were (21.82±8.52), (24.17±8.84)and (34.45±11.73) Hz, respectively.There was no statistically significant difference between the nodular and the massive types (P=0.144), while the difference between the nodular and diffuse type, the massive and diffuse types were statistically significant(P=0.000). The R2(*) values of infiltration group and non-infiltration group were (34.45±11.73) and (22.78±8.70) Hz , the R2(*) values of tumor thrombus group and non-tumor thrombus group were (31.20±12.17) and (24.21±9.90) Hz, the difference also had statistically significant(t=7.397 and 4.534, P=0.000 and 0.000). The AUC of R2(*) values for infiltration and tumor thrombus were 0.804, 0.681. R2(*) ≥24.68 Hz was the threshold value to diagnose the infiltration and tumor thrombus. CONCLUSION R2(*) value can be used as a MR non-enhancement quantitative index to evaluate the biological behavior of HCC.

Abstract
OBJECTIVE To evaluate the clinical value of a new device designed by ourselves for removing the disposable circumcision device (Shang ring). METHODS There were 264 patients undergoing Shang ring circumcision from August 2013 to June 2015. A total of 7 cases were lost follow-up and were excluded. The new device was applied for removing Shang ring in 150 patients after operation in Experimental group, and that was not applied in 107 cases in Control group. Values of basic demographic data, time for removing Shang ring, pain score, scar satisfaction, surgical satisfaction and complications were recorded and compared. RESULTS Time for removing Shang ring and pain score in Experimental group and Control group was 61.8±9.9 vs 127.4±41.6 s, 4.1±1.3 vs 6.8±1.4, respectively (both P<0.05). Satisfaction of surgery, percentage of willing to recommend Shang ring surgery to others in Experiment group and Control group was 9.3±0.7 vs 7.5±1.3, and 95.3% vs 79.4%, respectively (both P<0.05). Surgical satisfaction was correlated with pain score, time of removing Shang ring and appearance of incision scar (P<0.05). CONCLUSION The new device for removing the Shang ring could remove the ring rapidly, alleviate pain and improve surgical satisfaction.

Abstract
In recent years, Candida infections have been increasing significantly. This study was to investigate the distribution and fluconazole susceptibility of such infections. Totally, 3,056 clinical isolates were analysed, C. albicans was the most prevalent species from respiratory and vaginal specimens. However, non-albicans species constituted the majority of isolates from blood, urine, intensive care unit (ICU), organ transplant and burned patients. Similarly, Candida spp. from different specimens and clinical services had different degrees of susceptibility to fluconazole. Isolates from vagina and burned patients had the highest resistance rate, while all of the isolates from ascites and dermatological services were susceptible to fluconazole.

Abstract
The A1298C polymorphism of the methylenetetrahydrofolate reductase (MTHFR) gene has been reported to be associated with hepatocellular carcinoma (HCC), but there are conflicting results from previous studies. The present study aimed to investigate the association between this polymorphism and the risk of HCC using a meta-analysis of the published studies. Published literature from PubMed and Embase databases was systematically searched to identify relevant studies before October 2014. The Begg test was used to measure publication bias. Sensitivity analyses were performed to ensure the authenticity of the outcome. The meta-analysis results showed significant association between the MTHFR A1298C polymorphism and HCC risk (CC vs AA: OR = 0.52, 95%CI = 0.33-0.81; CC vs AC: OR = 0.50, 95%CI = 0.32-0.79; dominant model: OR = 1.94, 95%CI = 1.24-3.02; recessive model: OR = 1.00, 95%CI = 0.84-1.18). In the subgroup analysis, significant associations between the MTHFR A1298C polymorphism and HCC risk were found in Asians (CC vs AA: OR = 0.46, 95%CI = 0.27-0.78; CC vs AC: OR = 0.41, 95%CI = 0.24-0.71; dominant model: OR = 2.27, 95%CI = 1.33-3.86; recessive model: OR = 1.03, 95%CI = 0.86-1.24). Our results suggest that the MTHFR A1298C polymorphism might be related to increased risk of HCC in Asians. Further large and well-designed studies are needed to confirm these conclusions.
