At present, endoscopic retrograde cholangiopancreatography (ERCP) and T－tube sinus tract lithotomy are the main treatment methods for residual choledocholithiasis after surgery. However, these treatment methods have certain drawbacks； for example, ERCP may cause complications such as postoperative pancreatitis, bleeding, and perforation, and T－tube sinus tract lithotomy may cause sinus tract injury and bleeding. As a commonly used instrument in urology, flexible ureteroscope has the characteristics of small diameter and flexible angle and thus has a good prospect in the treatment of common bile duct stones. A patient with common bile duct stones was successfully treated by flexible ureteroscopy combined with a stone basket in Department of General Surgery, The Second People’s Hospital of Guizhou Province. Up to now, the patient has been followed up for seven months with no special discomfort, and magnetic resonance cholangiopancreatography showed no common bile duct stones. [ABSTRACT FROM AUTHOR]

Aiming at the problem of large number of parameters and low detection efficiency of the traditional target detection method in defect detection of electronic components, this paper proposes a target detection method based on the lightweight YOLOX detection network. Firstly, the backbone network is lightened using deeply separable convolution to reduce parameters and improve detection speed. Secondly, a spatial Pyramid-based channel attention model is constructed to filter and fuse features of different scales to enhance the feature weights of small size defects. In the feature fusion upsampling process, efficient channel attention is added to improve detection accuracy with slightly increased parameters. Finally, the EIoU loss function is used to optimize the IoU loss function, and the cosine annealing algorithm is used to make the model achieve the best detection effect. The model is tested on a self-made dataset of electronic component appearance defects, and the average detection accuracy reaches 98.96%, with a detection time of approximately 0.09 seconds per image. Compared with the original model, the detection speed is doubled and the model size is reduced by about 60%. The model is also validated on the PCB defect public dataset, achieving fast detection of target defects. [ABSTRACT FROM AUTHOR]

Objective: To investigate the clinical study of preoperative modified frailty index (mFI) combined with serum prostaglandin E2 (PGE2) and interleukin-17A (IL-17A) to predict postoperative delirium (POD) in elderly patients with hip replacement. Methods: 276 elderly patients with hip replacement who were admitted to West China Hospital of Sichuan University from January 2020 to July 2022 were selected, and they were divided into POD group and non-POD group according to the occurrence of POD. Preoperative mFI was calculated, and serum PGE2 and IL-17A levels were detected by enzyme-linked immunosorbent assay. Receiver operating characteristic (ROC) curve was used to analyze the predictive value of mFI, serum PGE2 and IL-17A levels on POD in elderly patients with hip replacement. Multivariate Logistic regression was used to analyze the influencing factors of POD in elderly patients with hip replacement. Results: The incidence of POD in 276 elderly patients with hip replacement was 17.03% (47/276). Compared with non-POD group, the mFI, serum PGE2 and IL-17A levels in the POD group were increased (P＜0.05). Multivariate Logistic regression analysis showed that age, diabetes, stroke, mFI, PGE2 and IL-17A were independent risk factors for POD in elderly patients with hip replacement (P＜0.05). ROC curve analysis showed that the area under the curve (AUC) of mFI combined with serum PGE2 and IL-17A predicted POD in elderly patients with hip replacement was greater than mFI, PGE2, and IL-17A predicted individually (P<0.05). Conclusion : Elevated mFI and serum PGE2 and IL-17A levels are independently associated with POD in elderly patients with hip replacement. The mFI combined with serum PGE2 and IL-17A is of high value in predicting POD in elderly patients with hip replacement, and which may be an auxiliary predictor of POD in elderly patients with hip replacement [ABSTRACT FROM AUTHOR]

To investigate the effect of the red/blue light quality ratio on the growth and metabolites accumulations of A.roxburghii and A.formosanus, the tissue culture plants of A. roxburghii and A. formosanus were treated with three LED lights of R2 B1（with Red/Blue ratio of 2:1）,R1 B2（with Red/Blue ratio of 1:2）,and W（white light）. After 60 d of illumination, the content of chlorophyll, soluble sugar, soluble protein, total phenols, and total flavonoids were determined by spectrophotometry, and the content of quercetin, isorhamnetin, kaempferol, ferulic acid, and chlorogenic acid were determined by HPLC combined with standards.Under the R2 B1 light, the fresh weight, dry weight, contents of chlorophyll and phenolic acid compounds of the two species reached the highest.The soluble protein content of the two species under the R1 B2 light reached the lowest.Under the R2 B1 light, the total phenol content of A.roxburghii was significantly higher than that of W.But under the R1 B2 light, the content of soluble sugar and total flavonoids of A.formosanus was significantly higher than that of W. Under the R2 B1 light, the contents of quercetin and the isorhamnetin in A.roxburghii were（36.52±0.91）and（61.35±2.45） μg.g-1,respectively, and the content of chlorogenic acid in A. formosanus was（40.09±3.79） μg.g-1.Therefore, the R2 B1 compound light can be used as a suitable light formula for A.roxburghii and A. formosanus,and it can provide scientific basis for the application of LED in the tissue culture of A. roxburghii and A. formosanus.
