To analyze the disease burden of hypertension in the elderly population from 1990 to 2021 and to predict future trends in China and globally, thereby providing insights for public health decision-making regarding older adults with hypertension in China. Data on hypertension-related deaths and disability adjusted life years (DALYs) for individuals aged ≥60 years was extracted from the Global Burden of Disease (GBD)2021 database for the world, China, and five sociodemographic index (SDI) regions. Age-standardized mortality and DALYs rates for hypertension in the elderly population were calculated, and Joinpoint regression was used to assess trend changes of disease burden, with results reported as average annual percentage change (AAPC). Additionally, subgroup analyses were conducted based on age and sex. The relative impact of aging, population growth, and epidemiological changes on disease burden was analyzed using a three-factor decomposition method. Future projections for the disease burden from 2022 to 2040 were performed using a Bayesian model. From 1990 to 2021, both age-standardized mortality and DALYs rates for hypertension in the elderly population demonstrated a significant downward trend globally and in China (both AAPC values were negative, all Although age-standardized mortality and DALYs rates for hypertension among the elderly in China have shown a downward trend over the past three decades, the absolute burden remains substantial. There is an urgent need for the formulation and implementation of more effective public health policies and clinical interventions to address this critical public health challenge.

OBJECTIVES:
The objectives of this study were to assess the quality of prosthetic prescriptions of removable partial dentures (RPDs) and to analyze the current situation of the communication and information delivery between clinicians and technicians.
METHODS:
All RPD prosthetic prescriptions received by a major dental laboratory in 4 weeks were involved in a quality audit, and the prescriptions were divided into three groups in accordance with the grades of clients. The filling of prosthetic prescriptions was recorded. The items in the prescriptions for audit included the general information of the patient, the general information of the clinician, the design diagram information, other detailed information, and the return date. The prescriptions were categorized into four levels on the basis of their quality by two quality inspectors who have been working for more than 10 years.
RESULTS:
A total of 916 prescriptions were collected and assessed. The names in the general information of the patient and the clinician were filled out best, both at the rate of 97.6% (n=894). The return date was filled out worst, only at the rate of 6.4% (n=59). Of those prescriptions, 86.8% (n=795) exhibited inadequate design diagram information. The results of the quality assessment demonstrated that 74.2% of prescriptions were assessed as noncompliant ones and failed to meet the acceptable clinical quality standard.
CONCLUSIONS
At present, the overall quality of RPD prosthetic prescriptions is poor. The responsibilities of clinicians and technicians are unclear, and the communication between them is not ideal.

Objective:To evaluate the expression level of hsa-miR-422a in hypertrophic scars and to identify the target genes of hsa-miR-422a along with their biological functions using bioinformatics approaches.Methods:From June 2020 to December 2020, tissue samples of 3 hypertrophic scar and 3 normal skin were collected from patients (3 males, 3 females, aged 20-42 years) in Department of Plastic and Reconstructive Surgery, Shanghai Ninth People′s Hospital, Shanghai Jiaotong University School of Medicine. Primary fibroblasts were isolated and cultured. Real-time quantitative PCR was performed to quantify the expression of hsa-miR-422a. To construct a ceRNA network, starbase and Target Scandata bases were utilized to predict genes as well as long noncoding RNAs (lncRNAs) that may sponge hsa-miR-422a. GO and KEGG pathway enrichment analyses were conducted on the target genes of hsa-miR-422a; protein-protein interaction (PPI) networks were constructed to identify the hub genes whose functions were predicted by functional enrichment analyses. The expression of hub genes was validated through real-time quantitative PCR in hypertrophic scars.Results:The expression of hsa-miR-422a was significantly lower in the hypertrophic scar tissue samples and fibroblasts compared to that in the normal skin ( P<0.05). 133 target genes as well as 1033 lncRNAs were predicted by starBase and TargetScandata bases and used to construct an hsa-miR-422a-centered ceRNA network. PPI networks of the target genes revealed 10 hub genes, including MAPK1, GRB2, and IGF1R, which were discovered to be related to protein serine/threonine/tyrosine kinase activity, ubiquitin protein ligase binding, fibroblast growth factor receptor signaling pathway, muscle cell proliferation, and many others; besides, they may be involved in FoxO, mTOR, Toll-like receptor, Ras, MAPK, PI3K-Akt signaling pathways and signaling pathways regulating pluripotency of stem cells. Three hub genes (MAPK1, GRB2, and IGF1R) were significantly upregulated in hypertrophic scars ( P<0.05). Conclusions:hsa-miR-422a is significantly downregulated in the hypertrophic scars and may target hub genes such as MAPK1 in ceRNA networks, ultimately modulating hypertrophic scar formation.

Objective:To investigate the prognostic value of metabolic parameters of 18F-fluorodeoxyglucose ( 18F-FDG) positron emission computed tomography/computed tomography(PET/CT) in advanced non-small cell lung cancer(NSCLC) treated with first-line immune checkpoint inhibitor (ICI) combined with chemotherapy. Methods:A retrospective study was conducted to evaluate patients with advanced NSCLC who underwent baseline PET/CT before treatment at the Affiliated Cancer Hospital of Zhengzhou University from 2019 to 2021. Receiver operating characteristic (ROC) curve analysis was used to determine the cut-offs for metabolic parameters of PET/CT, including total metabolic tumor volume (TMTV), total lesion glycolysis (TLG), and maximum standard uptake value (SUV max). Kaplan-Meier method, Log-rank test, and Cox regression model were used to calculate the overall survival (OS) and the progression-free survival(PFS). Results:A total of 44 patients were enrolled. Univariate analysis showed that the factors influencing PFS were TMTV and the number of metastatic sites ( χ2=4.19, 11.28, P<0.05) and the factors influencing OS were TMTV and TLG ( χ2=14.96, 6.05, P<0.05). Multivariate analysis suggested that number of metastatic sites was an independent prognostic marker for PFS ( P=0.011) and TMTV was an independent prognostic marker for OS ( P=0.038). Conclusions:TMTV is a prognostic indicator of OS while the number of metastatic sites is a prognostic indicator of PFS in advanced NSCLC patients who received first-line ICI combined with chemotherapy, but further prospective studies are needed.

Spinal muscular atrophy, lower extremity-predominant, 2A (SMALED2A) is a form of spinal muscular atrophy, which predominantly affects muscles of the lower extremity, characterized by early childhood onset of muscle weakness and atrophy. This disorder is caused by mutation in the BICD2 gene. This paper reports a case of SMALED2A with recurrent skin ulceration of both feet. Whole exome sequencing of this case revealed a chr9∶95527083_A>AGCC insertion mutation in the 5’UTR of BICD2 gene.

Dental caries and trauma are the most common oral diseases in children, which could result in defects of the teeth or detention. Maintenance of the primary dentition in a nonpathologic condition is important for oral health, craniofacial development, and the overall well-being of the children. In contemporary dentistry, primary anterior teeth defects are mainly treated with drugs, restorative treatments, or both. Restorative treatment is the most preferred method and includes direct restoration, full coronal restoration, post-and-core crowns, etc. This article reviews the available information regarding a variety of restorative treatments for primary incisor defects, including their backgrounds, clinical indications, clinical pathways, and related studies. The literature review shows that intraconal direct restoration is widely used on single surfaces. There are many kinds of full coronal restorations, and each has its own advantages. Pediatric resin-bonded strip crowns and zirconia crowns are the most popular and have excellent aesthetics. The use of post-and-core crowns for primary incisors is controversial. The absorbable post may be the next research hotspot. Therefore, treatment of severely destroyed primary incisors poses a challenge for pediatric dentists, as three important considerations must be kept in mind: children′s behavioral management, preservation of the tooth structure and parental satisfaction.

Numerical simulation of stent deployment is very important to the surgical planning and risk assess of the interventional treatment for the cardio-cerebrovascular diseases. Our group developed a framework to deploy the braided stent and the stent graft virtually by finite element simulation. By using the framework, the whole process of the deployment of the flow diverter to treat a cerebral aneurysm was simulated, and the deformation of the parent artery and the distributions of the stress in the parent artery wall were investigated. The results provided some information to improve the intervention of cerebral aneurysm and optimize the design of the flow diverter. Furthermore, the whole process of the deployment of the stent graft to treat an aortic dissection was simulated, and the distributions of the stress in the aortic wall were investigated when the different oversize ratio of the stent graft was selected. The simulation results proved that the maximum stress located at the position where the bare metal ring touched the artery wall. The results also can be applied to improve the intervention of the aortic dissection and the design of the stent graft.

Objective? To explore the effects of Roy's cognitive adaptation process theory on pediatric nursing courses. Methods? Totally 119 three-year specialized nursing students who were admitted in 2016 in Nanyang Medical College were selected as the treatment group by convenient sampling, while another 114 specialized nursing students admitted in 2015 were selected as the control group. Nursing students in the control group were taught using the conventional method, whereas nursing students in the treatment group were involved into four-step teaching activities according to Roy's cognitive adaptation process. The Learning Attitude Questionnaire for College Nursing Students and the Critical Thinking Rating Scale were used to evaluate the teaching effects at the end of these courses. Results? At the end of these courses, the treatment group scored higher than the control group on the whole and in different dimensions of the Learning Attitude Questionnaire (P<0.05). The treatment group also scored higher than the control group on the whole and in different dimensions of the Critical Thinking Rating Scale (P< 0.05). Conclusions? Multiple teaching methods based on Roy's cognitive adaptation process, when used in pediatric nursing courses, can enhance nursing students' learning attitude and critical thinking, which is worth promoting in other nursing courses.
