Objective The article was to observe the clinical efficacy of the application of terbinafine and mizolastine in com -bined treatment of chronic eczema ( CE) with dermatophytes infection , so as to define the etiology role of dermatophytes in allergic dis-eases. Methods All subjects were randomly divided into experiment group and control group .The experiment group was treated with the combination of terbinafine and mizolastine , while the control group took mizolastine orally alone .EASI grading , recovery rate and effective rate were evaluated at 2, 3 week after the treatment and EASI grading and recurrence rate were evaluated at 4 weeks after the treatment. Results 79 patients had finished the experiment .Significant difference was found in the effective rates between two groups at 3 weeks after treatment (P<0.05).At 4 weeks after the treatment, EASI value and recurrence rate in experiment group were obviously lower than those in control group (P<0.05). Conclusion Good therapeutic effect has been achieved through the ap-plication of terbinafine and mizolastine in combined treatment of CE with dermatophytes infection , which implies dermatophytes plays an important role in the etiology of CE .

Objective:To evaluate the role of autophagy in ischemia postconditioning (IPO)-induced attenuation of intestinal ischemia-reperfusion (I/R) injury in mice.Methods:Thirty-two SPF healthy adult male C57BL/6J mice, aged 9-12 weeks, weighing 25-29 g, were divided into 4 groups ( n=8 each) using a random number table method: sham operation group (group S), intestinal I/R group (group IIR), group IPO and IPO plus 3-methyladenine (3-MA) group (group IPO+ 3-MA). The model of intestinal I/R was established by occlusion of superior mesenteric artery for 45 min followed by 2-h reperfusion in anesthetized animals.The mice underwent 3 cycles of 30-s reperfusion followed by 30-s ischemia before restoration of reperfusion in group IPO.Blood samples from the femoral artery were collected at 2 h of reperfusion for determination of concentrations of serum diamine oxidase (DAO), D-lactate (D-LA) and intestinal fatty acid binding protein (I-FABP). The animals were then sacrificed and intestinal tissues were removed for microscopic examination of the pathologic changes which were scored according to Chiu and for determination of the expression of autophagy-related proteins Beclin-1 and p62 (by Western blot). The water content of intestinal tissues was calculated. Results:Compared with group S, the Chiu′s score, concentrations of serum DAO, D-LA and I-FABP, water content of intestinal tissues, and LC3Ⅱ/LC3Ⅰ ratio were significantly increased, Beclin-1 expression was up-regulated, and p62 expression was down-regulated in IIR, IPO and IPO+ 3-MA groups ( P<0.05). Compared with group IIR, the Chiu′s score, concentrations of serum DAO, D-LA and I-FABP, water content of intestinal tissues, and LC3Ⅱ/LC3Ⅰ ratio were significantly decreased, Beclin-1 expression was up-regulated, and p62 expression was down-regulated in group IPO ( P<0.05). Compared with group IPO, the Chiu′s score, concentrations of serum DAO, D-LA and I-FABP, and water content of intestinal tissues were significantly increased, LC3Ⅱ/LC3Ⅰratio was decreased, Beclin-1 expression was down-regulated, and p62 expression was up-regulated in group IPO+ 3-MA ( P<0.05). Conclusion:Autophagy is involved in ischemia postconditioning-induced attenuation of intestinal I/R injury in mice.

Leukemia is a common, multiple and dangerous blood disease, whose early diagnosis and treatment are very important. At present, the diagnosis of leukemia heavily relies on morphological examination of blood cell images by pathologists, which is tedious and time-consuming. Meanwhile, the diagnostic results are highly subjective, which may lead to misdiagnosis and missed diagnosis. To address the gap above, we proposed an improved Vision Transformer model for blood cell recognition. First, a faster R-CNN network was used to locate and extract individual blood cell slices from original images. Then, we split the single-cell image into multiple image patches and put them into the encoder layer for feature extraction. Based on the self-attention mechanism of the Transformer, we proposed a sparse attention module which could focus on the discriminative parts of blood cell images and improve the fine-grained feature representation ability of the model. Finally, a contrastive loss function was adopted to further increase the inter-class difference and intra-class consistency of the extracted features. Experimental results showed that the proposed module outperformed the other approaches and significantly improved the accuracy to 91.96% on the Munich single-cell morphological dataset of leukocytes, which is expected to provide a reference for physicians' clinical diagnosis.

Lactic acid is an important platform chemical. Especially with rapid development of poly (lactic acid) industry, the demand for L-lactic acid is continuously increasing. To further reduce the fermentation costs and improve the robustness of strains from industrial point of view, many modern biotechnological approaches have been applied to strain development. In this review, we briefly summarize recent advances in L-lactate fermentation by genetically modified microorganisms, including lactic acid bacteria, yeast, E. coli and Rhizopus species.
