To analyze the trends in disease burden and risk factors of depression among the elderly population in China from 1990 to 2021, and to provide a theoretical basis for the prevention, treatment, and policy-making of geriatric depression in China.

Data on the disease burden of geriatric depression in China from 1990 to 2021, including the number of incident cases, disability-adjusted life years (DALYs), incidence rate, and DALY rate, were extracted from the 2021 Global Burden of Disease (GBD) database.The Joinpoint regression model was used to analyze the trends by calculating the annual percentage change (APC) and average annual percentage change (AAPC).The autoregressive integrated moving average (ARIMA) model was employed to predict the disease burden of geriatric depression over the next five years.Population attributable fractions (PAFs) were used to describe the risk factors for geriatric depression in China in 1990 and 2021.

From 1990 to 2021, the number of incident cases and the incidence rate of geriatric depression in China showed an overall upward trend.The most significant increase in incidence was observed in the 60-64 age group, while the prevalence rate increased notably in the ≥ 95 age group.TheDALY rate showed the most pronounced upward trend in the 65-69 age group.The incidence, prevalence, and DALY rates of geriatric depression were higher in women than in men.Major risk factors included child hood sexual abuse and intimate partner violence, with the impact of intimate partner violence being particularly significant among women.The ARIMA model predicted that the incidence, prevalence, and DALY rates of geriatric depression in China would decline over the next five years, with a greater decline observed in women than in men.

From 1990 to 2021, the incidence, prevalence, and DALY rates of geriatric depression in China showed an overall upward trend, with higher rates observed in women than in men.Greater attention should be paid to the elderly female population, with a focus on early prevention to reduce the disease burden of geriatric depression.

Objective Using the weighted gene co-expression network analysis(WGCNA)to explore the key genes of aging associated with Alzheimer's disease(AD).Methods GSE132903 was selected from GEO database as the analysis dataset.The differential expressed genes(DEGs)of AD were screened,and visualized with volcano and heat map.Aging and senescence-associated genes(ASAGs)were downloaded from MsigDB,Aging Altas and CellAge databases.WGCNA screened the gene modules with the highest correlation with AD,and genes of key modules subsequently performed with gene ontology(GO),Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analysis.AD age-related differential expressed genes(ARDEGs)were obtained by taking intersection genes of DEGs,key module genes of WGCNA and ASAGs.Protein-protein interaction(PPI)network analysis was performed using the STRING database to find key node genes.The co-expression networks and associated functions of key genes were analyzed using the GeneMANIA database.The key genes were validated in Alzdata database.Results 226 DEGs,606 ASAGs and 8 ARDEGs were obtained.The top 5 key genes selected by PPI were SYP,STXBP1,VAMP2,CPLX1 and STX1A.Alzdata database verified that the expressions of 5 key genes in other brain regions of AD were down-regulated,except for no significant changes of VAMP2 in hippocampus and STXBP1 in frontal cortex,as well as no expression of CPLX1 in frontal cortex.The differential expression of VAMP2,STXBP1 and STX1A appeared in the early stage of AD,and CPLX1 was related to the pathological process of Tau.SYP and STXBP1 were related to the pathological processes of amyloid β-protein and Tau.Conclusion SYP,STXBP1,VAMP2,CPLX1 and STX1A are ARDEGs,which are expected to be potential diagnostic and therapeutic targets for AD.

The article summarizes relevant experiences and offers corresponding insights, enriching research cases and practical support in the quality management of palliative care, which may have practical application value for enhancing the homogeneity of palliative care services in the region.

Objective To explore the antitussive action site and potential mechanism of Shegan Zhike Capsule.Methods The mouse cough model induced by concentrated ammonia was used to observe the dose effect relationship of the antitussive effect of Shegan Zhike capsule.The central antitussive effect of Shegan Zhike capsule was observed by using the cough model induced by electrical stimulation of superior laryngeal nerve in guinea pigs.The peripheral antitussive effect of Shegan Zhike capsule was observed by using the cough model of capsaicin desensitized guinea pigs induced by mechanical stimulation.The model of chronic bronchitis in guinea pigs was established by smoking,and the effects of Shegan Zhike Capsule on vasoactive amines histamine(HA)and 5-hydroxytryptamine(5-HT)were observed.Results Shegan Zhike capsule could significantly reduce the number of coughs in mice at the doses of 43.00,86.00 and 172.00 mg extract·kg-1(P<0.05 or P<0.01).The low-dose group,the middle-dose group,and the high-dose group of Shegan Zhike Capsule did not significantly inhibit the cough inducing effect of electrical stimulation of guinea pig superior laryngeal nerve at 30 min and 60 min after administration.Shegan Zhike capsule could significantly inhibit the cough of capsaicin desensitized guinea pigs caused by mechanical stimulation in the low dose group at 60 min,the medium dose group at 30 min and the high dose group at 30 min and 60 min(P<0.05).Compared with the model control group,the content of HA in serum of guinea pigs in low,medium and high dose groups of Shegan Zhike capsule decreased significantly(P<0.05 or P<0.01).The content of serum 5-HT in the high dose group decreased significantly(P<0.05).Conclusion The antitussive effect of Shegan Zhike Capsule was not in the center,and its peripheral antitussive effect was related to the inhibition of RARs receptors,and vasoactive amines such as HA and 5-HT were also involved.

With the rapid development of clinical trials, the relevant medical research and molecular detection based on biological samples are closely related to the progress of clinical trials, making the role of biological samples in clinical trials increasingly obvious. The standardized supervision mode of biological samples is an important prerequisite for carrying out high-quality clinical trials. Although the laws and regulations related to clinical trials are becoming more and more perfect, there are still a large number of adverse events related to biological samples, which seriously affects the progress and results of clinical trials, and is one of the important challenges currently facing. Therefore, it is urgent to enhance the supervision of biological samples and improve the management methods of biological samples in clinical trials at this stage. Through in-depth discussion of the current status of biological sample management in clinical trials at home and abroad, this paper analyzed the issues existed during the supervision of biological samples, and supplemented the biological sample management methods by further combing the existing relevant laws and regulations and the Guidelines for the Ethical Management of Biological Samples in Clinical Trials, with a view to providing suggestions and ideas for optimizing the management mode of biological samples in clinical trials.

In the context of life health narratives, narrative foreclosure is considered as "the rupture or stagnation of the life narrative process". Narrative foreclosure occurs in people of all ages, and the life stories of those with narrative foreclosure often end prematurely or remain in a stagnant state that cannot be updated. The youth stage will experience three crises of narrative relationships rupture, including identity location, social and family narrative relationships rupture, which are the important reasons for youth narrative foreclosure. By analyzing the characteristics and manifestations of typical youth narrative foreclosures in literature and clinical practice, this paper aimed to draw more researchers to pay attention to the phenomenon of narrative foreclosure in youth groups, understand the importance of narrative empowerment, and help them improve their narrative literacy, and restart new life experiences, so as to break through the foreclosure from inside to outside, and achieve the physical and mental health of the subject.

Objective To evaluate endoscopy for the diagnosis of primary gastrointestinal mucosaassociated lymphoid tissue lymphoma (MALT lymphoma) and diffuse large B-cell lymphoma (DLBCL).Methods The clinical pathology,hematological/biochemical studies,and endoscopic data of 98 primary gastrointestinal MALT lymphoma and DLBCL patients from Aug 2010 to May 2017 were analyzed retrospectively.Results 17 patients had higher than normal LDH blood level (＞270 U/L).47 patients were Helicobacter pylori (Hp) positive;Gastrointestinal endoscopic study,including endoscopic mucosal resection (EMR)/endoscopic submucosal dissection (ESD) and endoscopic ultrasonography established diagnosis of MALT lymphoma and DLBCL in 96 out of 98 cases (98％).The endoscopic manifestations of MALT lymphoma and DLBCL were ulcerative,uplift,diffuse and infiltrative,and erosive,with ulcerative type as the dominant one.The follow-up examination showed that the survival ratio (88％) of MALT patients was higher than that of DLBCL(68％),and more patients with lower Ann Arbor stage survived (92％) than those with higher Ann Arbor stage (64％).Conclusion Endoscopic biopsy together with endoscopic ultrasonography makes definite diagnosis of MALT and DLBCL.

BACKGROUND: Currently, a variety of new dressings have been on the market, which are diversified and exhibit multifunctional trends. However, ideal wound dressings are still in exploration.OBJECTIVE: To introduce the basic physiological function and polymer advantage of dextran as well as its effects to promote wound healing in combination with other macromolecule materials, in order to impel the development of dextran as a new medical dressing .METHODS: A computer-based search of CNKI, PubMed, WanFang, VIP databases was performed to retrieve reviews or research articles addressing dextran and medical dressings published from January 2000 to December 2016. The keywords were dressing, dextran, wound healing in Chinese and English, respectively.Finally, 31 articles were included in result analysis.RESULTS AND CONCLUSION: Dextran has the physiological functions of promoting wound healing and immune function. These physiological functions are the basis of dextran as a medical dressing. Additionally, dextran has some polymer advantages, such as water absorption, biodegradability and non-toxicity. It is noteworthy that dextran can be combined with macromolecules to produce new polymer materials that can promote wound healing in animal experiments. Taken together, dextran, as a medical dressing, has a broad clinical prospect in wound healing.

OBJECTIVETo analyze the efficacy of Methylprednisolone hemisuccinate intratympanic injection for refractory noise induced deafness.

METHODSOne hundred and twenty cases (215 ears) of noise induced deafness were treated with either hormone group (107 ears) or with non hormone group (108 ears). Following prior interventions, 145 ears went on to receive intratympanic Methylprednisolone hemisuccinate injection twice a week.

RESULTSAfter Intratympanic therapy, the total effective rate was 46.2%. 32 of 71 ears (45.1%) demonstrated hearing improvement in hormone group and 35 of 74 ears (47.3%) in non hormone group. The difference was statistically insignificant (P = 0.788).

CONCLUSIONIntratympanic therapy appears to provide additional treatment benefits for patients with refractory noise induced deafness who have been treated with prior interventions. The outcome is not affected by pretreatment with hormone.
