Efficacy and Mechanism of Chinese Medicinal Compounds and Monomers from Chinese Medicinals against Colorectal Cancer： A Review / 中国实验方剂学杂志

Colorectal cancer （CRC） is one of the refractory malignant tumors of the digestive system worldwide. With limitations， the available clinical therapies are usually suspended or show unsatisfactory effect. Therefore， it is urgent to find and develop new candidate drugs specifically targeting the cancer with ideal efficacy， low toxicity， and low cost， and the solutions can be found in traditional Chinese medicine （TCM） which has a long history. In TCM， sovereign， ministry， assistant， and guiding medicinals are selected based on the syndrome differentiation， and it has shown remarkable efficacy on CRC in recent years. In particular， Chinese medicinal compounds and monomers from Chinese medicinals which have been applied in clinical settings are advantageous in the treatment of CRCs， as they improve the quality of life， alleviate clinical symptoms and toxic and side effects of chemotherapy， and prolong the survival of patients. Therefore， we retrieved the English and Chinese articles with "CRC"， "TCM"， "compound" and "monomer" as keywords， and summarized the progress in the treatment of CRC with Chinese medicinal compounds and monomers from Chinese medicinals from four aspects of "replenishing Qi and invigorating spleen"， "clearing heat and removing toxin"， "nourishing liver and kidney"， and "tonifying Qi and nourishing blood". However， Chinese medicine features multiple components， multiple targets， and multiple pathways， and in-depth research should be carried out on the application of Chinese medicinal compounds and monomers from Chinese medicinals in the treatment of CRC， in an attempt to minimize the pain and side effects and maximize the therapeutic effect. This study is expected to provide new insight into the treatment of CRC and a reference for further research on the efficacy and mechanism of Chinese medicine.

Construction and verification of an intelligent measurement model for diabetic foot ulcer / 中南大学学报(医学版)

OBJECTIVES@#The measurement of diabetic foot ulcers is important for the success in diabetic foot ulcer management. At present, it lacks the accurate and convenient measurement tools in clinical. In recent years, artificial intelligence technology has demonstrated the potential application value in the field of image segmentation and recognition. This study aims to construct an intelligent measurement model of diabetic foot ulcers based on the deep learning method, and to conduct preliminary verification.@*METHODS@#The data of 1 042 diabetic foot ulcers clinical samples were collected. The ulcers and color areas were manually labeled, of which 782 were used as the training data set and 260 as the test data set. The Mask RCNN ulcer tissue color semantic segmentation and RetinaNet scale digital scale target detection were used to build a model. The training data set was input into the model and iterated. The test data set was used to verify the intelligent measurement model.@*RESULTS@#This study established an intelligent measurement model of diabetic foot ulcers based on deep learning. The mean average precision@.5 intersection over union (mAP@.5IOU) of the color region segmentation in the training set and the test set were 87.9% and 63.9%, respectively; the mAP@.5IOU of the ruler scale digital detection in the training set and the test set were 96.5% and 83.4%, respectively. Compared with the manual measurement result of the test sample, the average error of the intelligent measurement result was about 3 mm.@*CONCLUSIONS@#The intelligent measurement model has good accuracy and robustness in measuring the diabetic foot ulcers. Future research can further optimize the model with larger-scale data samples.

Factors of insulin injection-related knowledge among registered nurses of internal medicine department of Grade 3 generalized hospitals in Shanghai / 现代临床护理

Objective To investigate the insulin injection-related knowledge of the registered nurses in first-class general hospitals in Shanghai and look into its influence factors. Methods Totally 331 nurses in the hospitals were enrolled in this study. Univariate and multivariate stepwise regression were used to analyze the factors which influenced the insulin injection-related . Results The aggregate score of insulin injection-related knowledge was 54.20 ± 7.64, and the score index was 67.75%. Multiple linear regression analysis showed that such factors as professional title and nursing experience and training in the endocrinology department were the main factors of insulin injection-related knowledge (all P<0.05). Conclusion We should enhance the training to promote the injection skills so that they can assist the patients to effectively control blood sugar and improve the quality of life.

The investigation of community type 2 diabetic patients with peripheral arterial disease and nursing countermeasures / 中国实用护理杂志

Objective To investigate the status of community type 2 diabetic patients with peripheral arterial disease,analyze the influencing factors and put forward nursing countermeasures.Methods 210 type 2 diabetic patients living in a community in Shanghai were enrolled in the investigation.ABI and arterial peak velocity were measured using Doppler blood flow detector,symptoms and signs of foot were assessed and related laboratory examinations,including HbA1c,HDL-C,LDL-C were tested.Results There were 49 cases of ABI ＜ 0.9.The proportion of abnormal color of foot skin,edema,abnormal pulsation of dorsal artery of foot and sense of coldness in group of ABI ＜ 0.9 were larger than group of ABI≥0.9.There was no statistical significance between the two groups in the pain at rest and intermittent claudication.Logistic stepwise regression analysis showed that age and LDL-C not up to the standard were risk factors of PAD and the peak of foot dorsal artery flow was a protective factor of PAD.Conclusions It's important to early screen for PAD and to adopt corresponding nursing measures on the basis of treatment.We hope to further prevent the development of PAD and effectively prevent diabetic foot.

The screening and analysis of influencing factors for risk population of diabetic foot in community / 中国实用护理杂志

Objective To investigate the status of risk population of diabetic foot in community and analyze the influencing factors.Methods 210 diabetes patients living in a community in Shanghai were enrolled,acoording to Gavin's weighted integral method with risk factors of diabetic foot,Doppler blood flow detector,Semmes Weistein 5.07 (10 g) nylon monofilament and 128Hz tuning fork were used to screen for the risk population of diabetic foot.Results Risk population of diabetic foot were 174 patients (82.9％),wherein the low risk group were 112 patients (53.4％),in the middle and high risk group were 62 people (29.5％).In addition to the Gavin's diabetic foot risk factors,different ages,cultural degrees,the values of FBG,PBG and HbAlc would also affect the risk level of diabetic foot.While the values of FBG,PBG and HbAlc of diabetes patients in the moderate and high risk group were significantly higher than those in the normal group.Conclusions We should make early screening for risk factors of diabetic foot and strengthen health education and management in order to effectively prevent diabetic foot.

Applicability of Bakes Caregiving Outcom Scale in the study of primary family caregivers' burden of stroke survivors / 中国实用护理杂志

Objective To investigate the applicability of Bakes Caregiving Outcom Scale(BCOS) in the study of primary family caregivers'burden of stroke survivors. Methods The BCOS was used to inves-tigate the 180 primary family caregivers of stroke survivors.The applicability of BCOS was evaluated by in-ternal consistency,construct validity and criterion-related validity. Results The correlation coefficient be-tween the items and the total BCOS score was 0.408～0.725 (P ＜ 0.01 ).The total Cronbach's α was 0.877.Factor analysis used for examining the construct validity showed that 3 components were extracted and their accumulated contribution rate reached 60.93%.Factor loading of each item ranged from 0.510 to 0.875.The criterion-related validity was - 0.461 by using self-rated burden as a criterion(P ＜ 0.01 ). Conclusions BCOS is applicable in the evaluation of the primary family caregivers' burden of stroke survivors.
