Objective To design a remote psychological service platform to solve the problems of elementary troops in lack of psychologists,psychological intervention means and effects.Methods A remote psychological service platform was developed with B/S architecture,ASP.NET and ADO.NET technologies,Visual Studio.NET 2008 development platform and C# language,which was composed of four functional modules of psychological classroom,video teaching and psychological counseling,psy-chological assessment and file management,and system management.Results The platform developed provided elementary troops with remote psychological service for psychological assessment,psychological counseling,psychological guidance,mental health education,professional training for health personnel and emergency intervention.Conclusion The platform developed gains advantages in deployment,professional service,timely response and confidentiality,and facilitates the same psychological service effect as face-to-face communication.[Chinese Medical Equipment Journal,2023,44(9):49-52]

Objective To explore the factors related to tympanic membrane perforation in children with acute suppurative otitis media,and to provide reference for clinical practice. Methods We reviewed the clinical data of 1274 children with acute suppurative otitis media from February 2017 to May 2020,and analyzed the factors related to tympanic membrane perforation. Results Tympanic membrane perforation occurred in 67 out of the 1274 children with acute suppurative otitis media,with the incidence of 5.27%.The univariate analysis showed that 11 factors including the duration of onset(

AIM:To study the growth-inhibiting and proapoptotic effects of Pim-1 kinase inhibitor SMI-4a on human acute myeloid leukemia cell line U937.METHODS:The effect of SMI-4a on U937 cell viability was measured by CCK-8 assay.The apoptotic rate was assessed by flow cytometry with Annexin V-PI staining and by fluorescence microscopy with Hoechst 33342 staining.Methylcellulose was used to assess colony formation ability of the cells.The expression of β-catenin in the cell cytosol and nucleus was detected by Western blot,and the expression of apoptosis-related proteins in the U937 cells was also examined.Intracellular distribution of β-catenin was detected by the method of immunofluorescence.RESULTS:SMI-4a inhibited the viability of U937 cells.Annexin V-PI staining showed that SMI-4a induced apoptosis in dose-and time-dependent manners.Hoechst 33342 staining also verified the apoptosis.SMI-4a significantly inhibited the colony formation capacity of the U937 cells.The results of Western blot demonstrated that SMI-4a upregulated the expression of PARP and Bax,downregulated the expression of Bcl-2 and change the distribution of β-catenin in intracellular compartment.Immunofluorescence observation found that SMI-4a decreased the expression level of β-catenin in the U937 cells.CONCLUSION:SMI-4a induces U937 cell apoptosis through regulating the expression of apoptosis-related genes.

<p><b>OBJECTIVE</b>To evaluate the clinical results of immediate implant and immediate restoration and to discuss the applying principles of these techniques.</p><p><b>METHODS</b>Fourteen cases underwent immediate implant surgery for 37 dental implants immediately after the teeth or roots were extracted. Among them, 6 cases (14 implants) received immediate restoration after implant placement. The second stage operation and final restoration were performed 4 months on average postoperatively, and the mean follow-up time was 22 months.</p><p><b>RESULTS</b>Two implants from 1 case were lost at 3 weeks after immediate implant and immediate restoration. The rest cases achieved good clinical results. Accumulative 4-year survival rate was 94.6%.</p><p><b>CONCLUSIONS</b>The result of immediate implant and immediate restoration is predictable if the cases are properly selected.</p>
