The effects of cyclooxygenase 2 (COX 2) on alcohol induced liver injury in rats were investigated. Rats were randomly divided into three groups: Control group was given with corn oil plus dextrose; Model group with corn oil plus ethanol; Treatment group with corn oil plus ethanol and a selective COX 2 inhibitor celecoxib. All materials were injected into stomach through intragastric tubes. Liver samples were analyzed with histopathology, fatty staining and immunohistochemistry. Glutathione s transferase (GST) activity of liver tissue and plasma were detected. Levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in serum were measured. Compared with the control group, positive fatty staining cells and expression of COX 2 in liver, level of ALT and AST in serum and activity of GST in plasma were all significantly increased in the model group, but the GST activity in liver was decreased. However, these changes were all reversed in the treatment group. The results show that the model of alcohol induced liver injury in rats has been set up successfully, the selective COX 2 inhibitor celecoxib can protect against alcohol induced liver injury in rats and COX 2 may play a role in alcohol induced liver injury

Neurological disorders comprise a variety of complex diseases in the central nervous system, which can be roughly classified as neurodegenerative diseases and psychiatric disorders. The basic and translational research of neurological disorders has been hindered by the difficulty in accessing the pathological center (i.e., the brain) in live patients. The rapid advancement of sequencing and array technologies has made it possible to investigate the disease mechanism and biomarkers from a systems perspective. In this review, recent progresses in the discovery of novel risk genes, treatment targets and peripheral biomarkers employing genomic technologies will be dis-cussed. Our major focus will be on two of the most heavily investigated neurological disorders, namely Alzheimer’s disease and autism spectrum disorder.

Background and objective Lymph node metastasis is one of the important factors affecting the tumornode-matastasis (TNM) staging of lung cancer.In patients with surgery, 13 groups and 14 groups of lymph nodes ignored because of the deep hidden in the lung.In this paper,the positive detection rate of 13 groups and the 14 groups of lymph nodes in non-small cell lung cancer (NSCLC) and their effects on pathological stage were studied.Methods 100 cases of NSCLC were collected from the Affiliated Hospital of Inner Mongolia Medical University as the research object,cut out the intrathoracic 2-12 group,13,14 lymph node metastasis rate for pathological examination,relationship factors of statistical analysis of the size of primary tumor,location,pathological type and lymph node.Results 100 cases of patients with intrathoracic lymph node metastasis rate was 47.0％,with the 10-12 groups lymph node,N2 lymph nodes,13,14 groups lymph node positive rate had significant differences (P＜0.05);T stage 13,14 groups of lymph node detection rate has statistically significant difference (P＜0.05);peripheral and central NSCLC stage N1 undetected rate no statistical difference (P＞0.05);various pathological types of tumors between N1 missed rate had no significant difference (P＞0.05).In addition,12 patients were found to have non-tumor-derived lobe lymph node metastasis.Conclusion It is necessary to detect the metastatic lymph nodes of 13,14 group and non-tumor-derived lobe in NSCLC.It is helpful to obtain accurate TNM staging and to guide postoperative treatment.

Transportation service is an important part of hospital logistics management. In 2023, a tertiary hospital centered on patient service and guided by lean management, launched an intelligent transportation service in the " Didi" mode on the basis of the medical internet of things platform. This practice investigated the status of hospital transportation services and developed an intelligent transportation system that includes three subsystems: task reception and generation, dispatch and command of transportation center, and handheld computer accepting order. At the same time, standardized business processes were developed and transportation service performance evaluations were implemented. This practice had gradually piloted and achieved intelligent management of hospital transportation services. As of December 2023, the hospital had completed a total of about 310 thousand transportation tasks, of which 70% were intelligent system dispatching tasks. The timely delivery service rate had increased from 58% in 2022 to 98% in 2023. This practice had improved the quality and efficiency of transportation services, promoted the high-quality development of hospital logistics management, which could provide references for other hospitals to improve logistics management efficiency.

Objective The aim of this study was to investigate the effects of Rad9 mutants with impaired DNA mismatch repair ( MMR) function on the tumorigenesis of colorectal cancer. Methods The colorectal cancer tumor samples were collected from 100 patients. The mutation profiles of human Rad9 ( hRad9) gene in these samples were detected by reverse transcriptase?polymerase chain reaction ( RT?PCR) and sequencing. The plasmid of pFLAG?hRad9 ( L101M ) was constructed following the QuickChange mutagenesis procedure and transfected into mRad9?deleted mouse cells ( mRad9-/- cells) . The expression of hRad9 protein was measured by western blot analysis. The MMR activity in live cells was detected by flow cytometry using the reporter plasmid for MMR function. Results Mutation from Leu to Met at the residue 101 ( L101M) of hRad9 gene was detected in 7 of the 100 samples. The mismatch repair efficiency of mRad9-/-+L101M cells ( mRad9?deleted mouse cells with ectopic expression of L101M hRad9 gene) was (34.0± 5. 6)%, which was significantly lower than that in the mRad9-/-+ hRad9 cells [ mRad9?deleted mouse cells with ectopic expression of hRad9 gene, (48.0±7.5)%, P<0.05]. After N?nitroso?N?methylurea (MNU) treatment, the survival rate of mRad9-/-+L101M cells was (33.7±5.9)%, which was significantly higher than that in the mRad9-/-+ hRad9 cells [(21.3±4.7)%, P<0.05]. Thus, ectopic expression of L101M hRad9 gene resulted in significantly reduced MMR activity and increased resistance to MNU. Furthermore, ectopic expression of hRad9 gene with mutation at the target residues of post?translational modification in mRad9-/- cells also led to a reduced MMR activity. Conclusion Rad9 mutants with impaired DNA mismatch repair function may promote tumorigenesis of colorectal cancer.

BACKGROUND:Nowadays,there are increasing reports on the digitization and visualization system of acupuncture points for adults in traditional Chinese medicine,and the digitization and visualization system of acupuncture points for children in traditional Chinese medicine and the simulation system of acupuncture manipulation for Mongolian medicine training have been reported.However,there are no reports on relevant systems for children in Mongolian medicine. OBJECTIVE:To develop a simulation system of acupuncture points for children in Mongolian medicine,in the hope that it can be used for clinical teaching,manipulation practice and research on acupuncture safety. METHODS:Based on the tomographic anatomical dataset of preschool boys,a three-dimensional(3D)digital virtual anatomical model of children with multiple internal organs and tissues was constructed by using PhotoShop.2021 and Digihuman Reconstruction System software.The relevant annotation information database of 27 acupoints such as Dinghui acupoint of Mongolian medicine was compiled by the Unity database language.The Mongolian gold needle and silver needle were selected to record the acupuncture point teaching video on the 3D printed head and neck resin model of children.In Unity3D software,children's anatomical model,acupoint annotation information database and acupuncture operation video were integrated and coded,and a 3D digital children's Mongolian acupuncture acupoint visualization system integrating simulation acupuncture training,clinical teaching and acupuncture safety research was successfully created. RESULTS AND CONCLUSION:This study was based on real children's specimens.In order to reduce the error of two-dimensional segmentation,the manual layer-by-layer segmentation section image method was used to ensure the accuracy of the 3D model to the greatest extent.The Digihuman Reconstruction System was used to extract and save the individual segmentation data while maximizing the accuracy of the 3D model.PhotoShop.2021 software was used to complete the 3D reconstruction of the outer skin of the head and neck of children and the internal bony structure,cervical spinal cord,blood vessels and nerves,muscles and ligaments.After 3D reconstruction,the basic morphology of each independent structure and the integrity of the overall contour were verified in MeshLab software and the final fine adjustment and anatomical position confirmation were conducted using 3-matic research 13.0 software.The real anatomical morphology of the head and neck of preschool children was successfully simulated and restored.Unity3D software was used to integrate the 3D model of children,acupuncture operation video and acupoint annotation database,and the 3D digital Mongolian acupuncture acupoint visualization system for children was successfully constructed.Based on the real continuous fault ultra-thin dataset of preschool boys in China,China's first 3D digitization and visualization system of acupuncture points in the head and neck of children in Mongolian medicine was developed.Compared with the previous acupuncture soft works,this system is more suitable for the anatomical morphological development characteristics of Asian children,and has a high value of application in the fields of research on the safety of acupuncture in Mongolian medicine,clinical teaching and acupuncture simulation training.
