Three years after fertilization, the results showed that the increments of DBH, height, individual volume and stock volume of stand, and the fertilizer benefit of the different fertilization treatments were higher than the control to varying degrees, and among them, 700 g/tree was the best for promoting the growth of Pinus elliottii. Two years fertilization, the soil nutrients were improved compared with before, pH values of different layers decreased, organic matter and rapid available K contents increased, and rapid available N content increased dra- matically with the upper layer having an increase higher than the lower one; rapid available P decreased at different levels with the upper layer having a decrease lower than the lower one; and proper application of fertilizer could promote the growth of Pisolithus tinctofius, and 7 months after fertilization, the number of Pisolithus fruiting body generally increased with the increase of the fertilizer within 100-800 g/tree. The yield and benefit per unit area could be increased by fertiliza- tion for 1 time in middle-aged Pinus elliottii plantations, and the best fertilizing amount was N-P-K fertilizer 700 g/tree.展开更多

Abdominal US, CT and MRI showed a tumor in segment 7 (S7) of the liver. Although imaging suggested hepatocellular carcinoma, laboratory tests showed no abnormality in liver function, hepatitis virus markers were negative, and tumor markers including protein induced by vitamin K absence or antagonist Ⅱ (PIVKA-Ⅱ), α-fetoprotein (AFP), carbohydrate antigen 19-9 (CA19-9), and carcinoembryonic antigen (CEA) were all within normal ranges. Upon aspiration biopsy of the liver, the histopathological diagnosis was moderately differentiated hepatocellular carcinoma. Therefore, right hepatectomy was performed. Although a part of the tumor was necrotic, about 60% of the viable part showed a clear-cell variant. Consequently, it was diagnosed as clear-cell hepatocellular carcinoma. It was noted that the background liver tissue was normal. This case is worthy of reporting because development of clear-cell hepatocellular carcinoma in the normal liver of a middle-aged woman is rarely seen.展开更多
文摘AIM:To evaluate the prevalence of early post-traumatic stress disorder(PTSD)among young and middle-aged patients who have suffered open globe injuries,and to identify the psychosocial factors influencing PTSD in these patients.METHODS:A total of 280 patients who underwent ocular trauma surgery between January 2023 and January 2024 were selected through convenience sampling.Data were collected using a custom-designed demographic questionnaire,the Connor-Davidson Resilience Scale(CDRISC),the Cognitive Emotion Regulation Questionnaire(C-ERRI),and the PTSD Checklist-Civilian Version(PCL-C).Univariate analysis and stepwise multiple linear regression analysis were performed to determine the factors affecting PTSD in these patients.RESULTS:The average PTSD score for the patients was 33.22±13.48.The scores for individual PTSD dimensions,ranked from highest to lowest,were recurrent traumatic experiences,heightened arousal,avoidance reactions,and social dysfunction.Positive PTSD symptoms were observed in 85 patients(30.36%).Univariate analysis indicated that gender,postoperative vision,marital status,psychological resilience,and rumination were significant factors affecting PTSD symptoms(χ^(2)/t=6.53,17.88,8.83,2.17,and 14.1,respectively;all P<0.05).Pearson correlation analysis showed a positive correlation between rumination and PTSD symptoms(r=0.73,P<0.01)and a negative correlation between psychological resilience and PTSD symptoms(r=-0.14,P<0.05).Stepwise multiple linear regression analysis identified postoperative vision(notably eye removal),rumination levels,and psychological resilience(optimism)as major factors influencing PTSD in these patients(R^(2)=0.57,P<0.001).CONCLUSION:Young and middle-aged patients with open globe injuries have a high incidence of PTSD.Significant risk factors for early PTSD include primary enucleation,high levels of rumination,and low psychological resilience(optimism).Conversely,patients with good postoperative vision recovery,low rumination levels,and high levels of optimism are less likely to develop PTSD.Healthcare providers should pay special attention to patients who undergo primary enucleation,strive to reduce their rumination levels,and enhance their psychological resilience,thereby promoting a positive and optimistic attitude towards their condition and reducing the incidence of PTSD.

文摘Background:The prevalence of multimorbidity is increasing,with a notable shift towards younger age groups.Methods:Convenience sampling was employed to select 15,988 young and middle-aged adults in Chongqing as the study population.The Apriori algorithm was used to identify the multimorbidity patterns within this population,while an unordered binary logistic regression model was applied to assess the association between sleep,diet and the risk of multimorbidity.Results:The study population had an average age of 39.2±10.1 years.Apriori association rules revealed that the most prevalent binary chronic disease multimorbidity pattern was dyslipidaemia+hypertension(14.78%),while the most common ternary chronic disease multimorbidity pattern was diabetes+dyslipidaemia+hypertension(9.66%).The logistic regression analysis revealed that a lower rating of sleep quality was associated with an elevated risk of multimorbidity(odds ratio(OR)=1.17,95%confidence interval(CI):1.01,1.36).Individuals who adhere to a meat-based diet(OR=1.45,95%CI:1.25,1.68)and those with elevated salt intake(OR=1.22,95%CI:1.01,1.47)were also observed to have an increased risk of multimorbidity.Additionally,a greater likelihood of multimorbidity was observed among those following a spicy diet(OR=1.3,95%CI:1.11,1.52)and consuming more oil(OR=1.16,95%CI:1.01,1.33).Conclusion:A poor sleep quality and a dietary preference for meat-based,salt,spicy and oils were found to be associated with an increased risk of multimorbidity progression among young and middle-aged populations.It is recommended that young and middle-aged adults should pay attention not only to sleep duration but also to sleep quality and improve dietary habits to reduce the likelihood of multimorbidity.
文摘Objective:To explore the potential categories and influencing factors of self-advocacy in young and middle-aged patients with breast cancer and to provide a theoretical basis for personalized intervention.Methods:From September 2023 to March 2024,314 young and middle-aged breast cancer patients were studied.Female cancer patients were surveyed using the self-advocacy scale,social support rating scale,and chronic health literacy scale.Latent profile analysis was used to investigate the heterogeneity and influencing factors of self-advocacy.Results:Self-advocacy among young and middle-aged breast cancer patients were classified into two potential categories:low advocacy-lack of support(51.7%)and high advocacy-effective communication(48.3%).Binary logistic regression analysis indicated that educational level,per capita monthly income,social support,and health literacy were significant influencing factors of these categories(P<0.05).Conclusion:Self-advocacy in young and middle-aged breast cancer patients demonstrates categorical heterogeneity.Identifying self-advocacy characteristics and implementing targeted intervention strategies—focused on self-efficacy and improving health literacy—can enhance self-advocacy in these patients.

文摘This study examined the factors associated with financial support in old age from three primary mechanisms-personal savings,family support,and social insurance-to explore the implications for the future development of China's rural social welfare system.Cross-sectional surveys of 1392 young and middle-aged rural residents were conducted in July and August2012.The results showed that while social insurance was increasingly acceptable,personal savings and family support still had fundamental value.Combining the three mechanisms,the rural old-age welfare system presented nontraditional features.China's new rural endowment insurance is discussed as a means to address the need for financial support among the rural aging population.
文摘Objective:To study the correlation of blood uric acid level with the degree of anxiety as well as the neurotransmitter and cytokine secretion in young and middle-aged patients with anxiety disorder.Methods: The young and middle-aged patients diagnosed with generalized anxiety disorder in our hospital between March 2015 and February 2018 were selected as the anxiety group, and the healthy subjects receiving physical examination during the same period were selected as the control group. Peripheral blood was collected to determine the contents of uric acid, neurotransmitters and cytokines, and Hamilton Anxiety Scale (HAMA) was adopted to judge the degree of anxiety.Results: The blood uric acid level of anxiety group was obviously higher than that of control group and the higher the HAMA scores, the more significant the rising of blood uric acid levels;serum 5-hydroxytryptamine (5-HT), norepinephrine (NE), dopamine (DA), interleukin-1α (IL-1α), IL-17 and interferon-γ (IFN-γ) contents of anxiety group were significantly higher than those of control group whereas neuropeptide Y (NPY), IL-4 and transforming growth factor-β (TGF-β) contents were significantly lower than those of control group;blood uric acid level of the anxiety group was positively correlated with 5-HT, NE, DA, IL-1 , IL-17 and IFN-γ contents, and negatively correlated with NPY, IL-4 and TGF-β contents.Conclusion: The rise of blood uric acid level in young and middle-aged patients with anxiety disorder is related to the aggravation of anxiety degree as well as the abnormal secretion of neurotransmitters and cytokines.

文摘BACKGROUND Arthritis is a prevalent and debilitating condition that affects a significant proportion of middle-aged and older adults worldwide.Characterized by chronic pain,inflammation,and joint dysfunction,arthritis can severely impact physical function,quality of life,and mental health.The overall burden of arthritis is further compounded in this population due to its frequent association with depression.As the global population both the prevalence and severity of arthritis are anticipated to increase.AIM To investigate depressive symptoms in the middle-aged and elderly arthritic population in China,a risk prediction model was constructed,and its effectiveness was validated.METHODS Using the China Health and Retirement Longitudinal Study 2018 data on middleaged and elderly arthritic individuals,the population was randomly divided into a training set(n=4349)and a validation set(n=1862)at a 7:3 ratio.Based on 10-fold cross-validation,least absolute shrinkage and selection regression was used to screen the model for the best predictor variables.Logistic regression was used to construct the nomogram model.Subject receiver operating characteristic and calibration curves were used to determine model differentiation and accuracy.Decision curve analysis was used to assess the net clinical benefit.RESULTS The prevalence of depressive symptoms in the middle-aged and elderly arthritis population in China was 47.1%,multifactorial logistic regression analyses revealed that gender,age,number of chronic diseases,number of pain sites,nighttime sleep time,education,audiological status,health status,and place of residence were all predictors of depressive symptoms.The area under the curve values for the training and validation sets were 0.740(95%confidence interval:0.726-0.755)and 0.731(95%confidence interval:0.709-0.754),respectively,indicating good model differentiation.The calibration curves demonstrated good prediction accuracy,and the decision curve analysis curves demonstrated good clinical utility.CONCLUSION The risk prediction model developed in this study has strong predictive performance and is useful for screening and assessing depression symptoms in middle-aged and elderly arthritis patients.
文摘This study used Arksey and O’Malley’s scoping review methodology as a framework and searched the following databases:PubMed,Embase,EBSCO,CINAHL,Web of Science,Cochrane Library,Scopus,CNKI,Wanfang,VIP,and the Chinese Biomedical Literature Database.The database is open to December 20,2023,and documents related to the fear of dementia among the elderly in the community are described and analyzed to provide a reference for future research in this field.At the same time,we screened,extracted,and summarized relevant information from 21 included documents(16 in English and 5 in Chinese),which consisted of 16 cross-sectional studies,2 quasi-experimental studies,2 randomized controlled studies,and 1 longitudinal study.Sixteen of the included documents mentioned the incidence or level of dementia fear among the elderly in the community,2 addressed the adverse effects of dementia fear,and 4 reported prevention and intervention measures for dementia fear.In total,there are 8 assessment tools,and the influencing factors are categorized into sociodemographic characteristics,psychological and behavioral characteristics,sociocultural background factors,and health and dementia-related factors.The final conclusion is that the fear of dementia is common among the elderly in the community.In the future,the application of research tools should be expanded among middle-aged individuals,with considerations for other types of dementia in mind.It is recommended to conduct large-scale,multi-center randomized controlled trials while confirming the intervention’s effect on different types of middle-aged and elderly individuals,focusing on the long-term impact of these intervention measures to promote healthy aging.

文摘In order to promote the growth of mid-aged Pinus elliottii plantation, the effects of different fertilizing amounts of formula fertilizer were studied on the growth, the soil and cost-benefit of 9 year-old Pinus el/iottii plantations in the north- ern part of Hunan, China. Three years after fertilization, the results showed that the increments of DBH, height, individual volume and stock volume of stand, and the fertilizer benefit of the different fertilization treatments were higher than the control to varying degrees, and among them, 700 g/tree was the best for promoting the growth of Pinus elliottii. Two years fertilization, the soil nutrients were improved compared with before, pH values of different layers decreased, organic matter and rapid available K contents increased, and rapid available N content increased dra- matically with the upper layer having an increase higher than the lower one; rapid available P decreased at different levels with the upper layer having a decrease lower than the lower one; and proper application of fertilizer could promote the growth of Pisolithus tinctofius, and 7 months after fertilization, the number of Pisolithus fruiting body generally increased with the increase of the fertilizer within 100-800 g/tree. The yield and benefit per unit area could be increased by fertiliza- tion for 1 time in middle-aged Pinus elliottii plantations, and the best fertilizing amount was N-P-K fertilizer 700 g/tree.
文摘A 36-year-old woman was admitted to our department for close examination of a liver tumor that was found during a medical checkup. Abdominal US, CT and MRI showed a tumor in segment 7 (S7) of the liver. Although imaging suggested hepatocellular carcinoma, laboratory tests showed no abnormality in liver function, hepatitis virus markers were negative, and tumor markers including protein induced by vitamin K absence or antagonist Ⅱ (PIVKA-Ⅱ), α-fetoprotein (AFP), carbohydrate antigen 19-9 (CA19-9), and carcinoembryonic antigen (CEA) were all within normal ranges. Upon aspiration biopsy of the liver, the histopathological diagnosis was moderately differentiated hepatocellular carcinoma. Therefore, right hepatectomy was performed. Although a part of the tumor was necrotic, about 60% of the viable part showed a clear-cell variant. Consequently, it was diagnosed as clear-cell hepatocellular carcinoma. It was noted that the background liver tissue was normal. This case is worthy of reporting because development of clear-cell hepatocellular carcinoma in the normal liver of a middle-aged woman is rarely seen.
