Objective To compare the efficacy of three different methods in the prevention of adhesion after the HEOS system for different degrees of intrauterine adhesions.Methods 284 patients with mild,moderate and severe intrauterine adhesions,who were treated with the HEOS system,were divided into three groups,the intrauterine device with sodium hyaluronate gel was placed in Group A,Foley water capsule tube with sodium hyaluronate gel was placed in Group B,and sodium hyaluronate gel was placed in Group C only.The recovery of uterine adhesion,improvement of menstruation,endometrial thickness,and adverse reactions were compared among the three groups.Results The mild intrauterine adhesions group showed statistical differences among the three groups(P<0.05).Group A had a higher menstrual improvement rate than Group C(P<0.017),and there was no significant difference in other therapeutic indicators(P>0.017).However,the adverse reaction rate in Group A was also higher than that in Group C(P<0.017).In the moderate intrauterine group,there was a significant difference in the improvement rate of intrauterine adhesions between Group B and the other two groups(P<0.017).Group A and B were higher than Group C in terms of menstrual status,endometrial thickness,and adverse reactions(P<0.017).In severe intrauterine adhesions,Group A had higher efficacy indicators than other groups(P<0.017).Conclusions The curative effect index and adverse reaction rate were analyzed,after operation.For the light,moderate,and severe intrauterine adhesions,sodium hyaluronate gel,Foley water capsule tube with sodium hyaluronate gel,and intrauterine device with sodium hyaluronate gel were the best choice for adhesion.Individual and hierarchical management can achieve good clinical effects,which is worth popularizing.

BACKGROUND:Studies have found that glucagon-like peptide-1 and its analogues have a significant neuroprotective effect,and some drugs have been applied to the clinical stage Ⅲ study of Alzheimer's disease.However,the mechanism of its neuroprotective effect is still unclear,which needs to be further explored and clarified. OBJECTIVE:To screen out the genes related to the pathogenesis of Alzheimer's disease and the related targets of semaglutide for the treatment of Alzheimer's disease based on bioinformatics and network pharmacology analyses,to identify the potential target genes by comprehensive analysis of the two and to verify them at the cellular level. METHODS:Using DisGeNET database,differentially expressed genes between Alzheimer's disease patients and healthy population were screened out.The chemical structure formula and two-dimensional structure diagram of semaglutide were obtained using PubChem online database.GO/KEGG enrichment analysis was performed using DAVID online database.A protein-protein interaction network was constructed by using the STRING database.The HPA database was used to determine the distribution characteristics of the target proteins in various human tissues.Finally,western blot was used to detect relevant protein expression in HT22 cells after semaglutide intervention. RESULTS AND CONCLUSION:With the dataset in DisGeNET database,3 374 differentially expressed genes between Alzheimer's disease patients and healthy people were obtained,and meanwhile,101 target genes of semaglutide potential drugs were obtained.There were 23 intersection genes between them.Ten key genes were identified based on the protein-protein interaction network,which were silent information regulator 1(SIRT1),CASP9,CCND1,CASP1,KEAP1,DLG4,CASP4,GRB2,GRIA1,and EDNRA.The results of GO gene functional annotation analysis of key genes showed that the positive regulatory activity of cysteine endopeptidase,the positive regulation of proteolysis,and the positive regulation of cysteine endopeptidase involved the cytoplasmic part of the apoptotic activity process;AMPA glutamate receptor complex,inflammatory complex,CARD domain binding,cysteine endopeptidase activity,and cysteine endopeptidase activity were involved in the apoptotic process.The results of KEGG signaling pathway analysis indicated that colorectal cancer,non-small cell carcinoma,and endometrial carcinoma were related to immune infiltration,inflammation and autophagic apoptosis.In addition,according to the association ranking of key genes and their distribution in different tissues of HPA online database,SIRT1 was identified as the most significant differential gene.The expression level of SIRT1 protein was significantly down-regulated in HT22 cells after β-amyloid protein 1-42 treatment,but it could be significantly increased after being treated with semaglutide.To conclude,SIRT1 may be a target gene for semaglutide in the treatment of Alzheimer's disease.

Objective:To explore the potential relationship between sugar metabolism,acid production and cariogenicity of Prevotella denticola.Methods:Morphological features of Prevotella denticola were observed and respectively cultured under incubation conditions with and without sugar and at different pH values.The growth characteristics of Prevotella denticola were detected by UV-Vis spectro-photometer and pH meter,the organic acid content in the culture supernatants of the cultures was detected by HPLC.Dentin slices were divided into control group,phosphoric acid group and the Prevotella denticola group and cultured in the corresponding mediu for 1 and 2 weeks respectively,the degree of demineralization of the samples was examined SEM and VHM.Results:Prevotella denticola fermen-ted sucrose and glucose,produced acids with its final pH values as low as 4.7,Succinic acid and acetic acid were its main metabolites.Prevotella denticola was moderately acid-tolerant.Furthermore,Prevotella denticola was able to cause dentin demineralization,and the Vickers hardness value of dentin samples in the Prevotella denticola group was significantly decreased compared with the control group(P＜0.05).Conclusion:The cariogenic capacity of Prevotella denticola may be related to its sugar metabolism and acid production.

Objective:To study the dosimetric differences of hippocampal-avoidance whole brain radiotherapy(HA-WBRT)between non-uniform 9-fields intensity-modulated radiotherapy-flatten filter(9F-IMRT-FF)and 9-fields intensity-modulated radiotherapy-flatten filter-free(9F-IMRT-FFF)mode.Methods:From January to December 2023,the simulated images of computed tomography(CT)location of 20 patients with intracranial metastases who had completed whole-brain radiotherapy at the Department of Radiotherapy of Chengde Central Hospital were selected.The radiotherapy plans of two kinds of modes of brand-new 9F-IMRT-FF and 9F-IMRT-FFF were redesigned in the planning system.The differences of dosimetric parameters of the two kinds of mode plans were compared,as well as the differences of irradiation efficiency of accelerator.Results:The exposure dose(D2%)of 2%volume of target region of planned target volume(PTV)of 9F-IMRT-FFF mode was significantly lower than that of 9F-IMRT-FF mode(t=-2.496,P<0.05).The exposure dose(D100%)of 100%volume of target region,the maximum dose(Dmax)and the mean dose(Dmean)of the left side of hippocampus of 9F-IMRT-FFF mode plan were significantly lower than those of 9F-IMRT-FF mode plan,with statistically significant(Z=-3.179,-3.018,-2.145,P<0.05),respectively.The D100%and Dmax of the right side of hippocampus of 9F-IMRT-FFF mode plan were significantly lower than those of 9F-IMRT-FF mode plan,with statistically significant(Z=-3.099,-3.260,P<0.05),respectively.The monitor unit(MU)value of 9F-IMRT-FFF mode plan increased by 25%than that of 9F-IMRT-FF mode plan,while the treatment time of 9F-IMRT-FFF mode plan shortened 38%than that of 9F-IMRT-FF mode plan,with statistically significant(t=-9.664,-13.312,P<0.05),respectively.Conclusion:Both the non-uniform 9F-IMRT-FF and the 9F-IMRT-FFF can meet the clinically requirement.The 9F-IMRT-FFF has better modulation capabilities in beams,which has more advantages in reducing the dose of radiotherapy for hippocampus,and reducing treatment time,and increasing treatment efficiency.

Objective:To analyze the satisfaction of elderly outpatient experience, based on a satisfaction questionnaire survey of outpatients in public hospitals, for references to improve the medical experience of elderly patients.Methods:This study extracted the satisfaction survey questionnaires for outpatients in second level and above public hospitals nationwide from the National Health Commission′s satisfaction survey platform from 2019 to 2022. The questionnaire content included six dimensions: registration experience, doctor-patient communication, nurse-patient communication, environment and labeling, privacy protection, and medical staff response, as well as overall satisfaction. The satisfaction, relative satisfaction, and dissatisfaction rates of elderly outpatients were analyzed using standardized assignment of question options, etc; T-test was used for inter group comparison.Results:A total of 10.095 7 million outpatient satisfaction questionnaires were included in this study, including 0.576 3 million questionnaires for elderly outpatients. From 2019 to 2022, the overall satisfaction of outpatients had been increasing year by year, and the overall satisfaction scores of elderly patients were significantly higher than that of non-elderly patients( P<0.01). The satisfaction scores of elderly patients in the nurse communication dimension(86.55 to 91.03 points) and relative satisfaction(1.000) were the higher in each year, while the satisfaction scores in the environment and identification dimension(81.05 to 86.03 points) and relative satisfaction(0.935 to 0.955) were lower. In 2019 and 2022, elderly patients had higher dissatisfaction rates in the two dimensions of registration experience(2.26%, 1.91%) and doctor communication(0.80%, 0.53%). Conclusions:From 2019 to 2022, the overall satisfaction of elderly patients in secondary and above public hospitals in China was relatively higher with a steady increasing tendency. However, there was still room for further improvement in the environment and labeling, cultural construction, and registration experience for elderly patients.

Objective To use bioinformatics analysis to identify the key genes and signaling pathways involved in cardiac dysfunction after acute ischemic stroke.Methods The GSE102558 dataset was downloaded from the Gene Expression Omnibus(GEO)database,and genes with values of P<0.05 and|log2FC|>0.6 were identified as being differentially expressed.The MCODE plugin in Cytoscape software performed a functional module analysis of the protein-protein interaction(PPI)network,while the CytoHubba plugin screened for core genes.Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analyses were also performed.A middle cerebral artery occlusion model was constructed to verify core gene expression using real-time PCR.Results Among the screened differential genes,385 were upregulated and 354 were downregulated.The top ten core genes were Col1a1,Col1a2,Col3a1,Fbn1,Postn,Col5a1,Mmp3,Eln,Acta2,and Timp3.The GO enrichment mainly involved the extracellular matrix,the collagen fiber tissue,vascular development,and protease binding.KEGG was mainly enriched in protein digestion and absorption,the relaxin pathway,advanced gly-cation end products-receptor for advanced glycation end products,and platelet activation.Real-time PCR verified that Col3a1and Postn expressions decreased in the heart tissue after acute ischemic stroke.Conclusion Col3a1and Postnexpressions may be closely associ-ated with cardiac dysfunction occurrence and development after acute ischemic stroke.

Objective: To investigate the risk factors for yersiniosis, so as to provide insights into prevention of yersiniosis. Methods: The patients with yersiniosis admitted to the clinics in the surveillance site of Chengbei Township of Jin'an District and Chengnan Township of Yu'an District in Lu'an City from 2013 to 2021 were included as the case group, and the healthy family members matched to cases were selected as the family control group, while normal residents with a 1︰2 match in the same village, gender, and age difference within 5 years were included in the community control group. Participants' demographics, hand-washing and eating habits, living environment hygiene, poultry and livestock feeding were collected using questionnaire surveys, and factors affecting yersiniosis were identified using a multivariable conditional logistic regression model. Results: There were 43 cases in the case group, with a median (interquartile range) age of 45 (34) years, 91 cases in the family control group, with a median (interquartile range) age of 36 (36) years and 86 cases in the community control group, with a median (interquartile range) age of 46 (34) years. Multivariable conditional logistic regression analysis showed that compared with the family control group, the habit of drinking unboiled water (OR=6.721, 95%CI: 1.765-25.588), and direct consumption of food stored in the refrigerator (OR=7.089, 95%CI: 1.873-26.829) were risk factors for yersiniosis in the case group; and compared with the community control group, not washing hands after contacting with poultry and livestock (OR=50.592, 95%CI: 2.758-927.997), habit of eating raw vegetables and fruits (OR=5.340, 95%CI: 1.022-27.887), direct consumption of food stored in the refrigerator (OR=19.973, 95%CI: 2.118-188.336), and unclean refrigerator (OR=12.692, 95%CI: 1.992-80.869) were risk factors for yersiniosis in the case group. Compared with the family and community control groups, not washing hands after contacting with poultry and livestock (OR=4.075, 95%CI: 1.427-11.637), habit of drinking unboiled water (OR=4.153, 95%CI: 1.331-12.957), habit of eating raw vegetables and fruits (OR=4.744, 95%CI: 1.609-13.993), and direct consumption of food stored in the refrigerator (OR=5.051, 95%CI: 1.773-14.395) were risk factors for yersiniosis in the control group. Conclusion Unhealthy habits such as eating raw vegetables and fruits, drinking unboiled water, direct consumption of food stored in the refrigerator, unclean refrigerator, and not washing hands after contacting poultry and livestock may increase the risk of yersiniosis.

Osteosarcoma is the most common primary solid bone malignancy. The main factor leading to recurrence and metastasis of osteosarcoma is resistance to chemotherapy drugs. Long non-coding RNAs can affect drug resistance in osteosarcoma by regulating epithelial-mesenchymal transition, cell autophagy, apoptosis, drug efflux, and cell cycle, suggesting that long non-coding RNAs may become new targets for drug resistance in osteosarcoma treatment.

BACKGROUND: LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer. METHODS: We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels. RESULTS: On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]). CONCLUSION: LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile. TRIAL REGISTRATION ClinicalTrials.gov, NCT04563936.
