From 13 aspects of preoperative education, preoperative optimization, anesthesia management, perioperative blood management, perioperative pain management, perioperative fluid management, perioperative temperature protection, infection prevention, thrombus prevention, postoperative nausea and vomiting, postoperative drainage, functional exercise, and perioperative rehabilitation promotion, 35 pieces of the best evidence for hip and knee replacement patients to accelerate rehabilitation nursing in the perioperative period was summarized.Conclusions:This study summarizes the best evidence of accelerated rehabilitation nursing in the perioperative period of hip and knee arthroplasty, aiming to build and standardize the accelerated rehabilitation nursing scheme in the perioperative period of hip and knee arthroplasty, so as to provide reference for clinical perioperative nursing.

Objective:To examine the associations of pre-pregnancy body mass index (BMI), gestational weight gain, and gestational diabetes mellitus (GDM) with early childhood BMI trajectories.Methods:A total of 1 227 mother-child pairs from the Peking University Birth Cohort in Tongzhou were included in this study. In the cohort, maternal pre-pregnancy weight, height, gestational weight gain, and GDM diagnosis were collected. The children were followed up at birth and at 1, 3, 6, 9, 12, 18, 24, 30, and 36 months of age to obtain height/length and weight data. The longitudinal data-based k-means clustering algorithm was used to identify early childhood BMI trajectory groups. The associations of maternal pre-pregnancy BMI, gestational weight gain, and GDM with early childhood BMI trajectories were analyzed using the logistic regression model. We further explored whether there is an interaction effect between pre-pregnancy overweight/obesity and excessive gestational weight gain on the risk of the high BMI trajectory in early childhood through multiplicative and additive interaction analyses. Results:The prevalence rates of overweight and obesity before pregnancy were 21.2% (260 cases) and 6.6% (81 cases) respectively. The prevalence of excessive gestational weight gain and GDM was 57.7% (708 cases) and 30.9% (379 cases). The early childhood BMI trajectories were named low, medium, and high trajectories, accounting for 30.5%, 45.4% and 24.1%, respectively. After controlling potential confounding factors, it was found that pre-pregnancy overweight ( OR=1.54, 95% CI: 1.12-2.12), obesity ( OR=2.33, 95% CI: 1.41-3.85), and excessive gestational weight gain ( OR=1.47, 95% CI: 1.10-1.97) were risk factors for being in the high BMI trajectory in early childhood. GDM was not significantly associated with early childhood BMI trajectories ( P>0.05). Compared with the independent effects of pre-pregnancy overweight/obesity ( OR=1.90, 95% CI: 1.17-3.09) and excessive gestational weight gain ( OR=1.45, 95% CI: 1.03-2.04), the risk of being in the high BMI trajectory in early childhood was greater when the two factors coexisted ( OR=2.38, 95% CI: 1.60-3.54). However, both the multiplicative and additive models showed no interaction effect between pre-pregnancy overweight/obesity and excessive gestational weight gain. Conclusions:Maternal pre-pregnancy overweight/obesity and excessive gestational weight gain are independent risk factors for children being in the high BMI trajectory in early childhood, providing scientific evidence for obesity prevention.

The TMEM family is widely distributed in the plasma membrane and organelle membrane, and has multiple biological functions. The TMEM family has different functions and mechanisms of action in different diseases. Recent research shows that TMEM family members play an important role in the pathogenesis of non tumor diseases, especially in cardiovascular, respiratory and nervous system diseases, such as atherosclerosis, Parkinson′s disease, depression, etc. This article reviews the mechanism of action of the TMEM family in non tumor diseases, which is of great significance for further revealing the disease mechanism and elucidating the biological functions of TMEM family members, and provides a new perspective for disease treatment strategies.

Objective To investigate the therapeutic mechanism of Gandou Bushen Decoction(GDBSD)for improving reproductive disorders in male mouse models of Wilson disease(WD).Methods Sixty male homozygous TX mice were randomized equally into 4 groups and treated with daily gavage of saline(WD model group),penicillamine(0.09 g/kg),or GDBSD(0.2 mL/10 g),or with intraperitoneal injection of U0126(20 mg/kg)in addition to GDBSD gavage,with 15 male DL mice as control.After 4 weeks of treatment,copper content in testicular tissue of the mice was detected,and histopathology of the testes and epididymis was examined using HE staining and electron microscopy.TUNEL staining was used to identify apoptotic cells in the testes.The protein expressions of Bcl-2,Cytc,caspase-3,ERK,and p-ERK in the testicular tissue were evaluated with Western blotting,and BrdU-positive cells were detected with immunohistochemical labeling.Sperm density,viability,malformation rate and fertility levels of male mice were studied.Results Treatment with penicillamine and GDBSD obviously improved pathological changes of the testis,increased sperm density and motility,lowered sperm abnormality rate,fertility levels and increased testicular JOHNSEN score of TK mice,but the therapeutic effect of GDBSD was blocked by U0126.GDBSD treatment significantly lowered Cytc and caspase-3 expressions and increased Bcl-2 expression in the testicular tissue of TX mice(P<0.05),while U0126 treatment significantly lowered testicular Bcl-2 expression level.No significant differences were found in total protein expression levels of ERK1/2 among the 5 groups,but p-ERK protein expression was significantly reduced in WD and U0126 groups and increased in penicillamine and GDBSD groups.Conclusion GDBSD can improve spermatogenesis and enhance fertility of male TX mice with WD possibly by activating the ERK signaling pathway to enhance proliferation and reduce apoptosis of the spermatogenic cells.

Compounds 1, 2, 4, and 7 showed inhibitory activity against nitric oxide production with IC₅₀ values of 43.34 ± 0.53, 40.00 ± 4.72, 25.88 ± 1.41, and 27.59 ± 2.69 μmol·L^-1, respectively.

Objective:To compare the association between body mass index(BMI)trajectories deter-mined by different methods and the risk of overweight in early childhood in a prospective cohort study,and to identify children with higher risk of obesity during critical growth windows of early childhood.Methods:A total of 1 330 children from Peking University Birth Cohort in Tongzhou(PKUBC-T)were included in this study.The children were followed up at birth,1,3,6,9,12,18,and 24 months and 3 years of age to obtain their height/length and weight data,and calculate BMI Z-score.Latent class growth mixture modeling(GMM)and longitudinal data-based k-means clustering algorithm(KML)were used to determine the grouping of early childhood BMI trajectories from birth to 24 mouths.Linear regres-sion was used to compare the association between early childhood BMI trajectories determined by different methods and BMI Z-score at 3 years of age.The predictive performance of early childhood BMI trajecto-ries determined by different methods in predicting the risk of overweight(BMI Z-score＞1)at 3 years was compared using the average area under the curve(AUC)of 5-fold cross-validation in Logistic regres-sion models.Results:In the study population included in this research,the three-category trajectories determined using GMM were classified as low,medium,and high,accounting for 39.7％,54.1％,and 6.2％of the participants,respectively.The two-category trajectories determined using the KML method were classified as low and high,representing 50.3％and 49.7％of the participants,respectively.The three-category trajectories determined using the KML method were classified as low,medium,and high,accounting for 31.1％,47.4％,and 21.5％of the participants,respectively.There were certain differ-ences in the growth patterns reflected by the early childhood BMI trajectories determined using different methods.Linear regression analysis found that after adjusting for maternal ethnicity,educational level,delivery mode,parity,maternal age at delivery,gestational week at delivery,children's gender,and breastfeeding at 1 month of age,the association between the high trajectory group in the three-category trajectories determined by the KML method(manifested by a slightly higher BMI at birth,followed by rapid growth during infancy and a stable-high BMI until 24 months)and BMI Z-scores at 3 years was the strongest.Logistic regression analysis revealed that the three-category trajectory grouping determined by the KML method had the best predictive performance for the risk of overweight at 3 years.The results were basically consistent after additional adjustment for the high bound score of the child's diet balanced index,average daily physical activity time,and screen time.Conclusion:This study used different methods to identify early childhood BMI trajectories with varying characteristics,and found that the high trajectory group determined by the KML method was better able to identify children with a higher risk of overweight in early childhood.This provides scientific evidence for selecting appropriate methods to de-fine early childhood BMI trajectories.

The biological characteristics and pathogenicity of Klebsiella oxytoca isolated from sick carrier pigeons in Gansu province were explored by morphological observations,biochemical testing,16S rRNA PCR analysis,and RNA sequencing.The drug resistance and pathogenicity of the isolated strains were studied by histopathological observation,drug susceptibility testing,and pathogenicity analysis.The livers,lungs,hearts,and other organs of the sick pigeons were bleeding.In addition,the livers were yellow and brittle,and the lungs were purulent.A Gram-negative,short,rod-shaped bacterium was successfully isolated from the sick pigeon.Pink,smooth,moist,and round colonies grew on MacConkey's agar.The result of the indigo matrix test was positive.The homology between the amplified 16S rRNA sequence and MN330093.1 was 100.00％,indicating that the sick pigeon was infected with K.oxytoca.The strain was named GS-BY-GG.K.Oxytoca GS-BY-GG was resistant to 10 drugs,including penicillin,ampicillin,and furazolidone,and sensitive to 5 others,which included florfenicol,meropenem,and gentamicin.Histopathological observation showed bleeding in multiple organs.The liver cells were irregu-larly arranged with brown-yellow pigmentation.Extensive cell necrosis and exfoliation were observed in the trachea and mucosal epithelium,with inflammatory cell infiltration in the mucosal layer.The isolates were highly pathogenic in specific pathogen-free chickens.These findings provide support for the clinical diagnosis and control of K.oxytoca GS-BY-GG.

Aim To study the main active components and potential mechanism of selenshenzhi prescription a-gainst esophageal cancer by network pharmacology and in vivo and in vitro experiments.Methods The com-mon target was extracted from TCMSP,OMIM and GeneCards databases,and the PPI network was con-structed using STRING database.DAVID database was used for GO and KEGG enrichment analysis,and a network was constructed based on STRING and DAVID database for in vivo and in vitro experimental verifica-tion.Results Prediction results showed that a total of 100 active ingredients and 749 related targets were ob-tained,and 168 common targets were obtained between selenoshenzhi recipe and esophageal cancer,which were involved in the PI3K-AKT signaling pathway and proteoglycan signaling pathways in cancer.Selenshenz-hi prescription was used to conduct preliminary verifi-cation of related targets for human esophageal cancer EC9706 based on in vitro experiments.The results showed that selenshenzhi prescription could significantly inhibit the proliferation of esophageal cancer cells and induce the apoptosis of EC9706 through the expression of Bax,Bcl-2,caspase-3 and other key apoptotic pro-teins.Lastly,the core target and pathway of selensh-enzhi prescription were preliminically verified based on in vivo animal experiments on nude mice with esopha-geal cancer.The results showed that selenshenzhi pre-scription could significantly inhibit tumor proliferation,promote tumor cell apoptosis,and induce tumor apop-tosis by regulating the expression of key proteins on PI3K/AKT signaling pathway.Conclusions Selensh-enzhi prescription can control the occurrence and de-velopment of esophageal cancer through the synergistic effect of multi-components,multi-targets and multi-pathways,and provide a theoretical basis for further clinical investigation of the mechanism of selenshenzhi prescription in the treatment of esophageal cancer in the future.
