At present, liver transplantation is the most effective method for the treatment of various end-stage liver diseases, and electronic health technology is a new medical service model, which can be used as an efficient and cost-effective alternative to the health management of liver transplant recipients. This paper summarizes the application of electronic health technology in postoperative health management of liver transplant recipients, including applications, robots, video conferencing, tablet computers, text messages, telephones and wearable devices, etc., summarizes the implementation effect of electronic health technology in health management of liver transplant recipients, and analyzes the limitations of research and application at the present stage. In order to provide basis and reference for Chinese medical staff to carry out electronic health technology in the health management of liver transplant recipients.

The symptom clusters increase the symptom distress of liver transplant recipients, reduces their treatment and nursing compliance, and greatly affects the prognosis quality of life of liver transplant recipients. This article reviews the concept, research status, assessment tools, influencing factors, and interventions for symptom clusters in liver transplant recipients, aiming to help clinical nurses formulate targeted interventions based on symptom clusters, provide effective symptom management for liver transplant recipients, reduce the physical and psychological damage caused by symptom clusters, and continuously improve the quality of life of liver transplant recipients.

Objective:To investigate the distribution of CGG repeat numbers in the FMR1 gene among reproductive-age women in China, providing data reference for carrier screening and genetic counseling of Fragile X syndrome. Methods:This cross-sectional study recruited 16 610 reproductive-age women from 12 medical institutions between July 2022 and October 2023. Peripheral venous blood samples (3 mL) were collected, and genomic DNA was extracted. The number of CGG repeats in the FMR1 gene was determined using the triplet-primed polymerase chain reaction (TP-PCR) combined with capillary electrophoresis technology. Statistical analyses were performed to assess the prevalence and distribution of CGG repeat expansions. Results:Among 16 610 women of childbearing age, 5 684 (34.220%) women had the same number of CGG repeats in the two alleles of FMR1 gene, and 10 926 (65.780%) women had different numbers of repeats in the two alleles. Among the 33 220 FMR1 alleles in 16 610 women of reproductive age, the most common CGG repeat numbers were 29 [48.645% (16 160/33 220)] and 30 [26.276% (8 729/33 220)], while the most frequent CGG genotype was CGG 29/29 [24.726% (4 107/16 610)]. The CGG repeat numbers of FMR1 gene were normal in 16 498 women (99.326%). Among the 112 women (0.674%) with CGG repeat abnormities, 96 (0.578%) women were classified as intermediate carriers, 15 (0.090%) as premutation carriers, and 1 (0.006%) as a full mutation carrier, whose CGG genotype was (36, >200). Conclusion:In the general reproductive-age female population in China, the normal CGG repeat numbers of the FMR1 gene account for 99.326%, while the intermediate carrier rate is 0.578%, and the combined carrier rate of the premutation and full mutation types is 0.096%.

A case of an adult patient who was admitted to the hospital with the primary complaint of dysuria was presented. CT imaging of the urinary tract revealed incomplete duplication of the bladder, accompanied by multiple diverticula in the left bladder. Urodynamic studies indicated low detrusor contraction of the bladder. Cystoscopy revealed that the left bladder was connected to the urethra, with both bladders linked by a narrow connection. Laparoscopic expansion of this junction alleviated dysuria; however, it did not significantly reduce bladder residual volume during the short-term follow-up.

In recent years,natural antimicrobial biomaterials have received widespread attention due to their rich sources,broad anti-microbial spectrum,high antimicrobial activity,good biocompatibility,etc.They play an important role in caries prevention and treat-ment by inhibiting the formation of biofilm and removing the formed biofilm.In this paper,we summarize the inhibitory effects of differ-ent natural antimicrobial biomaterials on Streptococcus mutans,the main caries-causing organism,and its biofilm,with a view to provi-ding theoretical references for caries prevention and treatment.

Objective In this study,we aimed to predict the inhibitory mechanism of Shenlingcao oral liquid(SLC)in non-small cell lung cancer(NSCLC)by network pharmacology and verify it by molecular docking and in vivo experiments.Methods The active ingredients and corresponding targets of SLC and NSCLC were obtained by database and literature search.Targets of SLC common to NSCLC were selected to construct the protein interaction network,and GO and KEGG enrichment analysis and molecular docking were performed.A Lewis lung cancer mouse model was constructed and divided into Model group,SH group,and SL group.The latter two groups were intragastrically administered 8.75 g SLC lyophilized powder/kg and 3.50 g SLC lyophilized powder/kg,respectively.After 14 days of drug intervention,tumor growth,pathological changes in tumor tissue,and apoptosis in tumor tissue were observed in tumor-bearing mice;changes in blood routine indexes and the tumor tissue expression of p-AKT,AKT,p-PI3K,PI3K,and Bcl-2 protein of mice were detected.The result of the KEGG enrichment analysis were verified.Results Network pharmacological analysis showed that there were 77 active ingredients,618 potential targets,1498 potential targets for NSCLC,and 179 drug and disease intersection targets.Target intersection enrichment analysis showed that they were mainly concentrated in the phosphatidylinositol 3 kinase-protein kinase B(PI3K-AKT)signaling pathway,mitogen-activated protein kinase(MAPK)signaling pathway,and other related pathways.Molecular docking showed that the top 10 core components had good bonding ability with the top 10 core targets.In the animal experiments,compared with the Model group,SH group and SL group had significantly decreased tumor volume and weight(P＜0.05,P＜0.01),and significantly decreased white blood cell,neutrophil,and monocyte numbers(P＜0.01,P＜0.001).Red blood cells,platelets,and hemoglobin were significantly increased(P＜0.05,P＜0.01,P＜0.001);apoptotic cells were significantly increased in early tumor tissue(P＜0.05,P＜0.01),and the protein expression levels of p-PI3K/PI3K,p-AKT/AKT,and Bcl-2/GAPDH were significantly decreased(P＜0.05,P＜0.01).The expression levels of PI3K,AKT1,and Bcl-2 genes were significantly decreased(P＜0.05,P＜0.01).Conclusions The mechanisms of SLC activity against NSCLC may be related to the activation of the PI3K-AKT pathway and the promotion of apoptosis.

AIM:To establish a population phar-macokinetic(PPK)model of high-dose methotrex-ate in pediatric patients with diverse malignancies.METHODS:The PPK model of methotrexate was de-veloped using non-linear mixed-effects model;body surface area(BSA)was incorporated by allo-metric size modelling.RESULTS:A two-compart-ment linear model best fitted the concentration da-ta,typical values for clearance(CL)and central compartment distribution volume(Vd)were re-vealed to be 4.51 L/(h·1.73 m2)and 15.47 L/1.73 m2,respectively.Age,BSA,serum creatinine(SCr)and genotypes of ABCC2 rs717620 and ABCC4 rs2274407 were retained in the final model.CON-CLUSION:Age,BSA,SCr and genotypes of ABCC2 rs717620 and ABCC4 rs2274407 were identified to be significantly affecting the clearance.
