Objective To prepare rabbit antibody against mouse AD-004 by AD-004 expressed in the prokaryotic expression system and to identify its distribution in the testis and adrenal. Methods The full-length cDNA of mouse AD-004 was cloned into PET28 plasmid, and the protein was induced in E. coli BL21 bacteria by adding IPTC and then purified by Ni2+ -NTA column. The purified protein was used as an immunogen to prepare polyclonal antibody ( pAb) of AD-004. The specificity of the antibody was detected by Western blotting. Immunohistochemical staining was performed in the mouse adrenal and testis via pAb of AD-004. Results Hisfused AD-004 was expressed efficiently in the prokaryotic system. Western blot analysis showed that the polyclonal antibody was duly bound to purified AD-004 with high specificity and sensitivity. AD-004 could be abundantly identified in the adrenal medulla and mainly expressed in the Leydig cells of testis. Conclusion The mouse protein of AD-004 is obtained from the prokaryotic expression system. The rabbit anti-AD-004 antibody has been prepared successfully. AD-004 protein is mainly localized in the interstitium of testis, suggesting that AD-004 may play a role in the synthesis of sex-steroid hormone.

OBJECTIVE:
To develop a deep features-based model to classify benign and malignant breast lesions on full- filed digital mammography.
METHODS:
The data of full-filed digital mammography in both craniocaudal view and mediolateral oblique view from 106 patients with breast neoplasms were analyzed. Twenty-three handcrafted features (HCF) were extracted from the images of the breast tumors and a suitable feature set of HCF was selected using -test. The deep features (DF) were extracted from the 3 pre-trained deep learning models, namely AlexNet, VGG16 and GoogLeNet. With abundant breast tumor information from the craniocaudal view and mediolateral oblique view, we combined the two extracted features (DF and HCF) as the two-view features. A multi-classifier model was finally constructed based on the combined HCF and DF sets. The classification ability of different deep learning networks was evaluated.
RESULTS:
Quantitative evaluation results showed that the proposed HCF+DF model outperformed HCF model, and AlexNet produced the best performances among the 3 deep learning models.
CONCLUSIONS
The proposed model that combines DF and HCF sets of breast tumors can effectively distinguish benign and malignant breast lesions on full-filed digital mammography.

【Objective】 To explore whether the effect of functional electrical stimulation combined with respiratory training on patients with mechanical ventilation is superior to that of single lung rehabilitation scheme. 【Methods】 We selected 90 patients with mechanical ventilation hospitalized in the central ICU of our hospital from March 2018 to October 2019 and randomly assigned them into the functional electrical stimulation group (30 cases), respiratory function training group (30 cases), and the combined rehabilitation group (functional electrical stimulation combined with respiratory training) (30 cases). The treatment time in the three groups was 40 minutes each time. The treatment was given once a day, 6 times a week, and lasted for 2 weeks. B-ultrasound was used to measure the changes of the diaphragm and calculate the score of diaphragm thickening. The success rate of weaning, incidence of ventilator-associated pneumonia (VAP), duration of mechanical ventilation, and length of stay in ICU can be quantified according to the clinical nursing records. 【Results】 There were significant differences in the success rate of weaning, incidence of VAP, time of mechanical ventilation, and length of ICU stay in the three groups. However, the success rate of weaning, incidence of VAP, time of mechanical ventilation, and the length of ICU stay in the combined rehabilitation group were better than those in the other two groups (P<0.05). 【Conclusion】 The effect of functional electrical stimulation combined with respiratory training on patients with mechanical ventilation is significantly better than that of single lung rehabilitation scheme. The former one is superior to the single rehabilitation scheme in improving the success rate of weaning, increasing the activity of diaphragm, shortening the time of mechanical ventilation, and the length of stay in ICU.

OBJECTIVE:To optimi ze the ratio of four comp onents of Compound renshen jianti formulation (Panax ginseng , Dioscorea oppositifolia ,Lycium barbarum fruit,Alpinia oxyphylla ),and to investigate its anti-fatigue activity and acute toxicity. METHODS:The water extract of Compound renshen jianti formulation was prepared by water extraction ,concentration and decompression drying. By single factor tests ,using weight-bearing swimming time as index ,the effects of four factors were investigated,such as the amount of P. ginseng ,D. oppositifolia ,L. barbarum fruit,A. oxyphylla . On the basis of single factor tests,using comprehensive score of weight-bearing swimming time ,serum urea nitrogen content ,liver glycogen content and AUC of blood lactate after exercise as index ,the formulation was optimized by Box-Behnken response surface method. The mice was divided into blank control group (water),positive control group (Renshen hongjingtian capsules ,0.135 g/kg)and compound low-dose,medium-dose and high-dose groups [the optimal ratio of Compound renshen jianti formulation extract (called“optimal compound formulation ”for short )4.08,8.16,12.24 g/kg,by crude drug] ,intragastric administration of drug or distilled water 20 mL/kg,once a day ,for consecutive 30 d. The weight-bearing swimming time ,the contents of serum urea nitrogen ,liver glycogen and blood lactate AUC after exercise were used to optimize its anti-fatigue activity of optimal compound formulation. The comprehensive score was calculated based on the measured data of mice in the compound formulation middle-dose group , and the difference between it and the theoretical prediction value was compared. The mice were given optimal compound formulation intragastrically (total dose 16.00 g/kg, by extract). The general state , body mass change , toxic characteristics and death of mice were observed and recorded for 14 days. Median lethal dose (LD50)and maximum tolerated dose (MTD)were measured. RESULTS :The optimal formulation ratio of Compound renshen jianti formulation included that P. ginseng 1.5 g,D. oppositifolia 10 g,L. barbarum fruit 10 g,A. oxyphylla 3 g. Results of anti-fatigue activity validation test showed that the optimal compound formulation could significantly prolonged weight-bearing swimming time ,reduced serum content of urea nitrogen ,blood lactate content and its AUC (except for low-dose group ),while significantly increased the content of liver glycogen (P<0.05 or P<0.01). Average comprehensive score of medium-dose group was 96.95,which was only 0.06% different from the theoretical prediction value of 97.01. The results of acute toxicity test showed that there was no death in mice. The oral MTD of the optimal compound formulation was more than 15 g/kg,which was non-toxic. CONCLUSIONS :The optimal Compound renshen jianti formulation has effective anti-fatigue activity of mice ,and has no significant toxic effect.
