Objective To evaluate the effect of rehabilitation training on rats with spinal cord injuries by Meta-analysis. Methods Ar-ticles were searched from PubMed( ~2013),CNKI(1989~2013), WanFang Data( ~2013),VIP(1989~2013),quality of included article was assessed with Jadad scale,and available data was analyzed with RevMan 5. 0 software. Results 287 related articles were identified,but only 11 eligible articles were included. The Meta-analysis of BBB score indicated that the rehabilitation training groups were better than con-trol groups. The BBB score[weighted mean difference(WMD) =1. 87,95%CI(1. 50,2. 33),Z=10. 02,P<0. 01]. There was significant diffence between two groups. Conclusion Rehabilitation training can improve the recover of hindlimb function.

Technical framework is centered on top-level design of smart hospitals. Guangdong Second Provincial General Hospital adopted hospital intelligent twins as its technical framework of the all-scenario intelligent construction. Its construction practices covered four layers of intelligent interaction, intelligent connection, intelligent hub and intelligent application. These practices can advance the construction of smart hospitals into the all-scenario intelligent stage, featuring intelligent medical treatment, intelligent service and intelligent management, thus providing reference for promoting the construction of smart hospitals and realizing the digital transformation of medical industry.

OBJECTIVETo investigate the expression of metastasis-associated colon cancer 1 (MACC1) protein in colorectal cancer and its clinical significance.

METHODSImmunohistochemistry method was used to determine the expression of MACC1 protein in colorectal cancer and normal colorectal mucosal tissues (>5 cm distance to cancer tissue). Statistic analysis was performed to investigate the association between clinicopathologic features and MACC1 expression.

RESULTSThe positive rate of MACC1 protein in colorectal cancer tissues was significantly higher than that in normal tissues [75%(72/96) vs. 14.6%(14/96), P<0.01, χ(2)=68.43]. Expression of MACC1 protein was associated with TNM staging (P<0.01, χ(2)=16.82) and distant metastasis (P<0.01, χ(2)=10.53), but not with age, gender, tumor size, differentiation degree, invasion depth, and lymph node metastasis(all P>0.05). Positive rate of MACC1 expression increased with the advanced TNM staging. When distant metastasis occurred, high expression of MACC1 protein in cancer tissues was found. During median 13(4 to 21) months of follow-up, 7 patients died, including 6(8.3%, 6/72) with high expression and 1(4.2%, 1/24) with low expression. Distant metastasis occurred in 9 patients, including 7 with high expression and 2 with low expression. Two patients had local relapse, whose MACC1 expressions were both high.

CONCLUSIONMACC1 protein is highly expressed in colorectal cancer tissues, which may be associated with the invasion and metastasis of colorectal cancer.

Atherosclerosis(AS) is an important pathological feature of cardiovascular diseases such as myocardial infarction,stroke and other highly fatal diseases. Phlegm and dampness are considered to be an important pathogenesis of AS,which is difficult to heal and can cause complications. The establishment of an animal model with AS and phlegm-dampness syndrome,which could reflect the features of traditional Chinese medicine(TCM),and objective evaluation system are an important element of modern integrated TCM and western medicine research on cardiovascular diseases. It is of great significance for TCM to prevent and treat cardiovascular diseases. This article summarizes the scientific connotations of traditional Chinese and western medicine for AS and phlegm-dampness syndrome,comprehensively summarizes the current status of construction and evaluation in experimental animal model,analyzes the problems of current model,and discusses the factors of model construction and evaluation. Our aim is to establish normalized and standardized animal model with AS of phlegm-dampness syndrome.

Aristolochic acids (AAs) have long been considered as a potent carcinogen due to its nephrotoxicity. Aristolochic acid I (AAI) reacts with DNA to form covalent aristolactam (AL)-DNA adducts, leading to subsequent A to T transversion mutation, commonly referred as AA mutational signature. Previous research inferred that AAs were widely implicated in liver cancer throughout Asia. In this study, we explored whether AAs exposure was the main cause of liver cancer in the context of HBV infection in mainland China. Totally 1256 liver cancer samples were randomly retrieved from 3 medical centers and a refined bioanalytical method was used to detect AAI-DNA adducts. 5.10% of these samples could be identified as AAI positive exposure. Whole genome sequencing suggested 8.41% of 107 liver cancer patients exhibited the dominant AA mutational signature, indicating a relatively low overall AAI exposure rate. In animal models, long-term administration of AAI barely increased liver tumorigenesis in adult mice, opposite from its tumor-inducing role when subjected to infant mice. Furthermore, AAI induced dose-dependent accumulation of AA-DNA adduct in target organs in adult mice, with the most detected in kidney instead of liver. Taken together, our data indicate that AA exposure was not the major threat of liver cancer in adulthood.
