Microstructure evolution and corrosion behavior of Fe-Al-based intermetallic aluminide coatings under acidic condition

Two Fe-Al-based intermetallic aluminide coatings were fabricated on 430-SS(Fe-Cr)and 304-SS(Fe-Cr-Ni)substrates by pressure-assisted solid diffusion bonding with coating on pure Fe as control.The microstructure and intermetallic phases of the coatings were characterized by SEM,EDS and EBSD.A network of Cr2Al13 with matrix of Fe4Al13 was formed by inter-diffusing of Al with the substrates.The corrosion behavior of intermetallic coatings was investigated in 0.5 mol/L HCl solution by mass-loss,OCP,Tafel plot and EIS.It was found that corrosion resistance was greatly enhanced by dozens of times after the addition of Cr and Ni compared with that on pure Fe.The presence of cracks in the coating on 430-SS provided a pathway for corrosion media to penetrate to the substrate and accelerated the corrosion rate.Moreover,the corrosion product was analyzed by XRD,demonstrating that the addition of Cr and Ni facilitated the formation of more corrosion resistant phases,and therefore improved corrosion resistance.

Two methods of lung biopsy for histological confirmation of acute fibrinous and organizing pneumonia:A case report

BACKGROUND Acute fibrinous and organizing pneumonia(AFOP)is a rare,noninfective lung disease,histologically characterized by a patchy distribution of intra-alveolar fibrin“balls”and organizing pneumonia.The clinical manifestations of AFOP are nonspecific.Diagnosis depends on pathology.Surgical lung biopsy is optimal for tissue sampling to diagnose AFOP.However,many patients have no tolerance to the operation,including mentally and physically.There is still no standard therapy for AFOP and the methods remain controversial.Therefore,further clinical attention and discussion are warranted.CASE SUMMARY A 53-year-old woman presented with fever,cough and dyspnea for 15 d.Antiinfective therapy was ineffective.Chest computed tomography showed bilateral patchy consolidation,especially in the lower lobes.We performed both ultrasound-guided transbronchial lung biopsy and ultrasound-guided percutaneous fine needle puncture at different lung lesion locations.Both samples supported the diagnosis of AFOP.The patient had a good clinical course after treatment with methylprednisolone,and no side effects of steroids.CONCLUSION Percutaneous needle biopsy combined with transbronchial lung biopsies may be a good choice in the absence of surgical biopsy.Methylprednisolone alone is effective in the treatment of idiopathic AFOP.

Effect of Chinese Herbal Medicine Jinlida Granule in Treatment of Patients with Impaired Glucose Tolerance

Background：Diabetes mellitus （DM） remains a major health problem worldwide.Several clinical trials have shown the superiority of the Traditional Chinese Medicine in delaying or reversing the development and progression of DM.This study aimed to evaluate the efficacy of Jinlida （JLD） granule,a Chinese herbal recipe,in the treatment of impaired glucose tolerance （IGT） and its effect on the prevention of DM.Methods：Sixty-five IGT patients were randomized to receive one bag of JLD granules three times daily （JLD group,n =34） or no drug intervention （control group,n =31） for 12 weeks.Oral glucose tolerance test,glycated hemoglobin A1c （HbA1c）,body mass index,blood lipids levels,fasting insulin,and insulin resistance calculated using homeostatic model assessment （HOMA-IR） of all the patients were observed and compared before and after the treatment.Results：Sixty-one participants completed the trial （32 in JLD group and 29 in the control group）.There were statistically significant decreases in HbA1c （P 〈 0.001）,2-h plasma glucose （P 〈 0.001）,and HOMA-IR （P =0.029） in JLD group compared with the control group after 12 weeks of treatment.After 12 weeks of treatment,two （6.9%） patients returned to normal blood glucose,and five （17.2%） patients turned into DM in control group,while in the JLD group,14 （43.8%） returned to normal blood glucose and 2 （6.2%） turned into DM.There was a significant difference in the number of subjects who had normal glucose at the end of the study between two groups （P =0.001）.Conclusions：JLD granule effectively improved glucose control,increased the conversion of IGT to normal glucose,and improved the insulin resistance in patients with IGT.This Chinese herbal medicine may have a clinical value for IGT.

Effects of Exogenous Spermidine on PhotosystemⅡof Wheat Seedlings Under Water Stress

The effects of exogenous spermidine （Spd） on lipid peroxidation, relative plasma membrane permeability, photosystem Ⅱ （PSII） gene expression and PSII photochemical activity in water-stressed wheat seedlings were investigated. The decrease in relative water content （RWC）, Chl content, and 2,6-dichlorophenol indophenol （DCIP） photoreduction of PSII, and increases in electrolyte leakage of plasma membranes and malonyldialdehyde （MDA） in water-stressed leaves was alleviated by Spd pretreatment. Furthermore, Western and Northern blot analysis showed that decreases in the PSll major proteins D1, D2 and LHCII and the transcripts of corresponding genes psbA, psbD and cab were also alleviated by Spd pretreatment under water stress. These results suggest that the application of exogenous Spd protects PSII against water stress at both the transcriptional level and the translational level, and allows PSII to retain a higher activity level during water stress. The protective role of Spd in the photosynthetic apparatus also is discussed.

Allelic frequency distributions of 21 non-combined DNA index system STR loci in a Russian ethnic minority group from Inner Mongolia,China

We studied the allelic frequency distributions and statistical forensic parameters of 21 new short tandem repeat(STR)loci and the amelogenin locus,which are not included in the combined DNA index system(CODIS),in a Russian ethnic minority group from the Inner Mongolia Autonomous Region,China.A total of 114 bloodstain samples from unrelated individuals were extracted and co-amplified with four fluorescence-labeled primers in a multiplex polymerase chain reaction(PCR)system.Using capillary electrophoresis,the PCR products of the 21 STR loci were separated and genotyped.A total of 161 alleles were observed in the Russian ethnic minority group,and corresponding allelic frequencies ranged from 0.0044 to 0.5965.The 21 non-CODIS STR loci of the Russian ethnic minority group were characterized by high genetic diversity and therefore may be useful for elucidating the population's genetic background,for individual identification,and for paternity testing in forensic practice.

Incidence and clinical correlates of anger attacks in Chinese patients with obsessive-compulsive disorder

Objective: Anger attacks have been observed in patients with obsessive-compulsive disorder(OCD), often triggered by obsessional triggers. However, few studies have reported the clinical characteristics and correlates of anger attacks among Chinese patients with OCD. Methods: A total of 90 adults with a primary diagnosis of OCD, ranging from 15 to 78 years old, participated in the study. Participants were administered the Rage Outbursts and Anger Rating Scale(ROARS), Yale-Brown Obsessive-Compulsive Scale-Second Edition, and Brown Assessment of Beliefs Scale by a trained clinician. Patients completed the Obsessive-Compulsive Inventory-Revised and Depression Anxiety Stress Scale-21. Results: A total of 31.3% of participants reported anger outbursts in the past week, and ROARS scores had no significant correlation with age, duration of illness, OCD severity, depression, or stress. However, ROARS scores were negatively related to education level, and positively related to obsessing symptoms and anxiety. Conclusions: These data suggest that anger attacks are relatively common in Chinese patients with OCD. The severity of anger attacks is related to educational level, obsessing symptoms, and anxiety, which may be a latent variable reflecting executive functioning and emotion regulation skills.
