ObjectiveTo develop a community-family management model for older adults with mild cognitive impairment (MCI) and to formulate detailed application specifications, and to fully leverage the initiative of communities and families under limited resource conditions, for achieving community-based early detection and early intervention for older adults with MCI. MethodsA systematic literature review was conducted to identify pertinent publications. Corpus-based research methodologies were employed to extract, refine, integrate and synthesize management elements, thereby establishing the specific content and service processes for each stage of the management model. Utilizing the 5W2H analytical framework, essential elements such as management stakeholders, target populations, content and methods for each stage were delineated. The model and its application guidelines were finalized through expert consultation and demonstration. ResultsAn expert evaluation of the management model yielded mean scores of 4.84, 4.32 and 4.84 for acceptability, feasibility and systematicity, respectively. By integrating the identified core elements with expert ratings and feedback, the final iteration of the community-family management model for older adults with MCI was formulated. This model comprised of five stages: screening and identification, comprehensive assessment, intervention planning, monitoring and referral pathways to ensure implementation, and enhanced support for communities, family members and caregivers. Additionally, it included 18 specific application guidelines. ConclusionThe proposed management model may theoretically help delay cognitive decline, improve cognitive function and potentially promote reversal from MCI to normal cognition. It may also enhance the awareness and coping capacity of older adults and their families, strengthen community healthcare professionals' ability to early identify and manage MCI.

Objective To investigate the biomechanical characteristics of the mandibular anterior teeth intrusion assisted by buccal mini-implants,so as to provide theoretical guidance for the clinical treatment of deep overbite and other conditions requiring intrusion of the mandibular anterior teeth.Methods A finite element model of implant screws,clear aligners(CAs)and mandibular complex including the mandibular dentition,periodontal ligament(PDL)and alveolar bone was constructed.The model was designed with 0.2 mm intrusion in the mandibular anterior teeth.Seven groups were set:without traction,30 g,50 g,100 g,150 g,200 g,and 250 g force groups.The stress and displacement of the teeth as well as the related stress distributions of PDL and CAs in each group after loading were analyzed.Results Without traction and under different traction forces,the mandibular anterior teeth tended to be tipped and intruded.With the increase of traction force,the increasing trend was manifested in the vertical displacement and labial displacement of the mandibular anterior teeth.When the traction force reached 200 g,the vertical displacement showed a significant increase,the subsequent increase then showed a tendency to flatten.The ratio of the labial tipping displacement to the intrusive displacement of the mandibular anterior teeth showed a decreasing trend with the increase of traction force.Within a reasonable force range,increasing traction force led to greater bodily intrusion of the anterior teeth.When the traction force was less than 150 g,the mandibular posterior teeth exhibited a tendency of extrusion.When the traction force of more than 150 g was applied,it showed a tendency of intrusion.The PDL stress was concentrated on the labial and cervical surface of the anterior teeth.Conclusions Intrusion efficiency of the mandibular anterior teeth has been effectively improved with CAs assisted by buccal mini-implants.Moreover,the traction force of the mini-implants has a significant impact on the movement of the mandibular anterior teeth.Based on a comprehensive analysis of factors such as the displacement trend of the mandibular dentition and the PDL stress,the optimal force value for buccal traction of the mini-implants to intrude the mandibular anterior teeth can be selected as 150-200 g force.

BACKGROUND:miRNAs expression has been reported to be associated with hepatic and renal fibrosis,and dermal fibrogenesis. Moreover,a targeted regulatory relationship between miR-192-5p and epidermal regulators has been demonstrated in gouty arthritis.OBJECTIVE:To investigate the expression and regulatory role of miR-192-5p in hypertrophic scar and to verify whether there is a targeted regulatory relationship between miR-192-5p and epidermal regulators. METHODS:(1) Six cases of hypertrophic scar tissue and six cases of normal skin tissue were collected from the First Affiliated Hospital of Xinjiang Medical University. And miR-192-5p and epidermal regulator mRNA expression were detected by qRT-PCR. (2) The primary hypertrophic scar fibroblasts were obtained using tissue explant method and cultured to 3-6 generations for subsequent experiments. There were three groups in the experiment:negative control group,miR-192-5p mimic group and miR-192-5p inhibitor group. The latter two groups were transfected with the corresponding sequences. Cell proliferation viability was detected by the cell counting kit-8 assay and EdU kit;and the migration ability was detected by the cell scratch test. Cell apoptosis was detected by flow cytometry. The gene and protein expressions of epidermal regulator,type Ⅰ collagen,type Ⅲ collagen and α-smooth muscle actin were detected by qRT-PCR and western blot,respectively. miR-192-5p targets were predicted by a bioinformatics website,and target binding was validated by dual luciferase assay. RESULTS AND CONCLUSION:(1) Compared with normal skin tissues and their fibroblasts,miR-192-5p and epidermal regulator were highly expressed in hypertrophic scar and hypertrophic scar fibroblasts (P<0.05 or P<0.01). (2) After overexpression of miR-192-5p,cell proliferation was enhanced (P<0.05) and EdU positive cell rate increased (P<0.01) when compared with the negative control group;after inhibition of miR-192-5p,cell viability (P<0.05) and EdU positive rate decreased (P<0.05). (3) At 24 hours after overexpression of miR-192-5p,compared with the negative control group,the area between cell scratches and apoptosis rate decreased in the miR-192-5p mimic group (P<0.05) but increased in the miR-192-5p inhibitor group (P<0.01). (4) At 48 hours after transfection,the mRNA and protein levels of epidermal regulator were significantly decreased in the miR-192-5p mimic group,while the mRNA and protein levels of type Ⅰ collagen,type Ⅲ collagen and α-smooth muscle actin were significantly increased (P<0.05 or P<0.01). The miR-192-5p inhibitor group showed opposite changes in the above four indicators (P<0.05 or P<0.01). (5) The Targetscan website predicted that epidermal regulator had a potential binding site for miR-192-5p. (6) Dual luciferase assays showed that miR-192-5p could bind to epidermal regulator in a targeted manner. To conclude,overexpression of miR-192-5p can decrease the expression of epidermal regulator,and the two may be negatively regulated,suggesting that regulation of epidermal regulator may play a role in inhibiting the proliferation of hypertrophic scar fibroblasts.

Objective To evaluate the effectiveness of active screening in improving the detection rate of carbape-nem-resistant Enterobacterales(CRE)in the intensive care units(ICUs).Methods From July 2023 to June 2024,active screening of rectal swab CRE was conducted on ICU patients in 10 hospitals.ICU patients who underwent ac-tive screening from July 2023 to June 2024 were selected as the study group,while those who did not undergo active screening from July 2022 to June 2023 were selected as the control group.Difference in CRE detection rates between the two groups of patients was compared.Results A total of 7 803 ICU patients were included in the study group,744 CRE strains were detected,with a detection rate of 9.53％,out of which 304 CRE strains were detected through routine detection(detection rate 3.90％),3 707 patients underwent active screen,440 CRE strains were detected(detection rate 11.87％).7 561 ICU patients were included in the control group,out of which 250 CRE strains were detected through routine detection,with a detection rate of 3.31％.There was a statistically significant difference in the overall detection rate of CRE between two groups of patients(x2=246.18,P＜0.001).In the study group,CRE detection rate of active screening(11.87％)was higher than that of routine detection(3.90％),with statistically significant difference(x2=264.26,P＜0.001).A total of 17 CRE strains were detected from the study group.The proportions of Klebsiella pneumoniae(80.92％vs 73.41％)and Serratia marcescens(2.30％vs0.23％)in the routine detection group were both higher than in the active screening group,while the proportion of Escherichia coli in the routine detection group was lower(8.22％vs 19.55％),all with statistically significant differences(all P＜0.05).Conclusion The prevalence of CRE in ICUs is relatively high,with a wide range of bac-terial species.Active screening can improve the detection rate of CRE.

Mass vaccination represents a highly effective strategy for accelerating disease control while simultaneously reducing incidence and mortality rates. By developing comprehensive plans and standards for mass vaccination, it is feasible to optimize resource allocation and swiftly enhance vaccination coverage, thereby preventing, controlling, or interrupting outbreaks or epidemics of specific infectious diseases. To standardize the mass vaccination process and establish a population immunity barrier in an orderly, efficient, and safe manner, a panel of experts was convened to develop the Recommendations on Mass Vaccination. These recommendations are grounded in the requirements of relevant policies and regulations in China, as well as the insights gained from the mass vaccination campaign for COVID-19 vaccines conducted in the country. The recommendations outline the system requirements pertaining to initiation conditions, departmental coordination, responsibilities, mobilization, operational specifications, and responses to vaccine reactions, among other aspects of mass vaccination implementation, so as to serve as a reference for future mass vaccination initiatives and the formulation of related policies.

Background and purpose:There are few studies on the quality of life after transanal total mesorectal excision(TaTME)for rectal cancer,and there is a lack of evidence-based research.This study aimed to evaluate the impact of TaTME in comparison to laparoscopic total mesorectal excision(LaTME)on postoperative quality of life in patients.Methods:A retrospective analysis was conducted on clinical and pathological data from rectal cancer patients who underwent LaTME and TaTME between September 2019 and September 2022 at Renhe Hospital,Baoshan District,Shanghai,and Fudan University Shanghai Cancer Center.All the patients completed a set of validated questionnaires one year postoperatively,including the EORCT QLQ-C30,Low Anterior Resection Syndrome(LARS)score,International Prostate Symptom Score(IPSS),Generalized Anxiety Disorder-7(GAD-7),and Patient Health Questionnaire-9(PHQ-9).Comparative analysis of these survey results was performed.The study was approved by the Ethics Committee of Renhe Hospital,Baoshan District,Shanghai.The Strengthening the Reporting of Observational Studies in Epidemiology(STROBE)checklist was followed for this study.Results:A total of 39 patients in the TaTME group and 38 patients in the LaTME group were included.There were no statistically significant differences between two groups regarding demographic variables such as gender and age,as well as clinical factors including tumor distance from the anal verge,tumor stage,and preoperative neoadjuvant treatment protocols.Analysis of EORCT QLQ-C30 results indicated equivalent overall quality of life between the two groups;however,the TaTME group reported significantly more severe insomnia(P=0.020).No significant differences were observed in LARS severity or total scores between the groups,though the TaTME group demonstrated superior functional outcomes in terms of incontinence for liquid stools and clustering of stools(P=0.007,P=0.004).Additionally,both groups exhibited comparable results in IPSS,and levels of depression and anxiety.Conclusion:The findings suggest that TaTME and LaTME yield similar outcomes in terms of anal and urinary function,overall quality of life,and psychological health,indicating that it is a viable and safe alternative to LaTME in terms of postoperative quality of life.
