Chronic obstructive pulmonary disease （COPD） is a common clinical chronic airway disease with high morbidity， high mortality， a heavy disease burden， and complex mechanisms that have not been fully elucidated. Clinical problems promote the continuous progress of basic research. The establishment and evaluation of animal models is an important way to delve into the pathogenesis and treatment strategies of COPD. On the basis of the etiology， pathogenesis， diagnostic criteria， and syndrome differentiation of COPD in traditional Chinese medicine （TCM） and Western medicine， this paper summarizes the establishment methods and characteristics of existing animal models of COPD and analyzes the fitting degree of the models with the disease characteristics in Western medicine and syndrome characteristics in TCM. The results showed that the animal models of COPD in Western medicine were mainly induced by single factors and compound factors， and the model with the highest fitting degree was established by cigarette smoke combined with lipopolysaccharide and hormone. The model showed a fitting degree of 84% with the disease characteristics in Western medicine and 70% with the syndrome characteristics in TCM， being consistent with the clinical characteristics of COPD induced by multiple factors. Most of the animal models of COPD in TCM were established on the basis of disease models and combined with TCM etiology and pathogenesis characteristics， and prepared by syndrome differentiation. Among them， the model of accumulation of cold and water retention in lung had the highest fitting degree of 92% with the TCM diagnostic criteria. The models of phlegm-heat obstructing lung and phlegm-stasis obstructing lung had the fitting degree of 94% with clinical manifestations in Western medicine and the highest fitting degree with the diagnostic criteria in Western medicine. Different animal models of COPD have their own advantages and disadvantages， and most of them simply replicate the manifestations of COPD at a certain stage， failing to reflect the multiple causes and the dynamic changes of TCM etiology and pathogenesis. Moreover， the syndromes of these models fail to match the clinical syndromes in TCM. Therefore， establishing the animal models reflecting clinical characteristics of COPD in TCM and Western medicine and improving the model evaluation criteria are important contents to promote the overall development of integrated traditional Chinese and western medicine for COPD.

Objective·To retrieve and evaluate evidence related to weight management during endocrine therapy for prostate cancer patients,and summarize the best evidence available.Methods·The PIPOST model was adopted to construct evidence-based questions.Following the"6S"model of evidence resources,a systematic computer-based search was conducted to retrieve relevant evidence on weight management during prostate cancer endocrine therapy from various databases and websites,including Guidelines International Network,BMJ Best Practice,UpToDate,JBI Evidence-Based Healthcare Center Database,American Guidelines Network,Medlive,Cochrane Library,PubMed,CINAHL,Web of Science,Embase,CNKI,Chinese Biomedical Literature Database,Wanfang Database,and VIP Database,as well as the websites of the American Urological Association,European Urological Association,and Urological Branch of Chinese Medical Association.The evidence retrieved included guidelines,clinical decisions,recommended practices,expert consensuses,evidence summaries,systematic reviews,and original studies.The search period spanned from database establishment to December 2023.Two researchers independently evaluated the quality of the included literature.The included articles were read one by one and summarized according to themes.Priority was given to high-level,high-quality,and newly published authoritative literature during evidence screening and extraction.The included and extracted evidence was uniformly classified into levels 1?5 according to the JBI evidence pre-classification and evidence recommendation level system,and the evidence recommendations were divided into strongly recommended(Grade A)and weakly recommended(Grade B).Results·A total of 12 articles were retrieved,consisting of 4 guidelines,3 expert consensuses,2 evidence summaries,2 randomized controlled trials,and 1 quasi-experimental study.All 12 articles were rated as high quality and were included.The best evidence was summarized into 8 aspects:weight management assessment and monitoring,multidisciplinary collaboration,personalized support,family involvement strategies,nutrition management strategies,exercise management strategies,health education,and follow-up management.Conclusion·The best evidence for weight management during endocrine therapy for prostate cancer is summarized into eight aspects.In clinical application,specific clinical situations and patient characteristics should also be considered to improve the effectiveness of clinical interventions and the quality of care.

Objective To analyze the factors influencing iodine nutritional status in pregnant women dur-ing pregnancy,based on thyroid function and thyroid autoantibody levels,and to explore the association between iodine nutritional abnormalities and pregnancy outcomes.Methods A total of 838 pregnant women who underwent routine prenatal checkups at Qinghai Provincial People's Hospital between January 2021 and June 2023 were pro-spectively enrolled in this study.All participants were followed until delivery.Seven cases were lost to follow-up,resulting in a final sample size of 831 participants.Among them,276 were in the first trimester,384 in the second trimester,and 171 in the third trimester.Data on urinary iodine concentration(UIC),urinary creatinine(UCr),thyroid function indicators,and thyroid autoantibodies were collected.Based on their iodine nutritional status,the participants were categorized into either the iodine-sufficient group or the iodine-abnormal group(including iodine-deficient,iodine-hyper-sufficient,and iodine-excessive subgroups).This study analyzed the iodine nutritional sta-tus of pregnant women during different gestational periods,compared thyroid function indices,prevalence of thy-roid diseases,and the positivity rates of thyroid peroxidase antibody(TPOAb),thyroglobulin antibody(TGAb),and thyroid-stimulating hormone receptor antibody(TRAb)among different iodine status groups.Additionally,ad-verse pregnancy outcomes were compared across groups.Multivariate logistic regression analysis was conducted to identify risk factors associated with iodine abnormalities during pregnancy,and a predictive model was developed to assess its potential predictive value.Results Among the 831 pregnant women included in the study,373 cases(44.89％)exhibited iodine sufficiency,while 458 cases(55.11％)presented with iodine abnormalities,including 282 cases of iodine deficiency,144 cases of iodine hypersufficiency,and 32 cases of iodine excess.No statistically significant differences were observed in the iodine nutritional status across different trimesters(P>0.05).The se-rum level of thyroid-stimulating hormone(TSH)was significantly higher in the iodine abnormal group compared to the iodine sufficient group(P<0.05).Additionally,the iodine abnormal group demonstrated higher positivity rates of TPOAb alone,TGAb,and TRAb,as well as increased incidence of thyroid dysfunction and total adverse pregnancy outcomes compared to the iodine sufficient group(all P<0.05).These adverse indicators were also sig-nificantly elevated in the iodine-deficient,iodine super-sufficient,and iodine overdose subgroups compared to the iodine sufficient group(P<0.05).Elevated serum TSH levels and the presence of TPOAb,TGAb,and TRAb were identified as risk factors for iodine abnormalities during pregnancy(P<0.05).The predictive model con-structed for identifying iodine abnormalities in pregnant women demonstrated an area under the curve(AUC)of 0.876,with a sensitivity of 72.27％and a specificity of 89.01％.Conclusions The prevalence of iodine nutritional abnormalities among pregnant women during pregnancy was high,with most cases presenting iodine deficiency.These abnormalities were associated with thyroid function,thyroid autoimmunity,and pregnancy outcomes,but showed no significant correlation with gestational age.Furthermore,the prediction model developed based on iden-tified risk factors demonstrated effective performance in predicting iodine nutritional abnormalities during preg-nancy.

Objective To investigate the effect of the rs3765467 polymorphism of glucagon-like peptide-1 receptor(GLP-1R)gene on the efficacy of Liraglutide(Lir)in patients with type 2 diabetes mellitus(T2DM)and metabolic associated fatty liver disease(MAFLD).Methods A total of 281 patients with T2DM from May 2022 to May 2023 were selected,including 125 patients with simple T2DM(T2DM group)and 156 patients with T2DM combined with MAFLD(T2DM+MAFLD group).120 healthy individuals during the same period were selected as the control(NC)group.The related indexes of glucose and lipid metabolism were detected.The polymorphism of GLP-1R gene rs3765467 was detected.Results BMI,FPG,HbA1c,HOMA-IR and TG in each group increased in turn(P<0.05),while the distribution frequency of genotype GG and allele G decreased in turn(P<0.05).TC and LDL-C in T2DM and T2DM+MAFLD groups were higher than those in NC group(P<0.05).TC and TG levels in genotype GA/AA patients were significantly higher than those in genotype GG patients(P<0.05).Compared with before treatment,the levels of BMI,FPG,HbA1c,HOMA-IR,TC,TG and LDL-C in T2DM patients with MAFLD were significantly decreased after Lir treatment(P<0.05).There was no significant difference in BMI and related indexes of glucose and lipid metabolism in GG and GA/AA patients before and after Lir treatment(P>0.05).Conclusions The distribution frequency of GG and G allele at rs3765467 of GLP-1R gene is reduced in T2DM patients with MAFLD.The carrying of allele A was associated with increased TC and TG levels,but did not affect the efficacy of Lir in reducing weight and improving glycolipid metabolism.

China is currently in an accelerated stage of population aging, and brain diseases pose a significant threat to the health of the elderly. " Preventing brain aging and maintaining brain health" has become a high-level goal of healthy aging. During the process of aging, the physiological and psychological states of elderly people change, making them prone to nervousness and exhaustion, which can disturb the brain spirit, damage the brain collaterals, and severely endanger brain health. Starting from the holistic view of cultivating both body and spirit in traditional Chinese medicine, based on the physical and mental characteristics of the elderly, this paper applies the concept and method of " relaxation and tranquility" in the protection of elderly brain health, focusing on maintaining relaxation and tranquility in both physical and mental aspects. Specific measures include emphasizing subjective consciousness, relaxing the heart and calming down; utilizing the daoyin method, relaxing the body and calming down, combining relaxation and tranquility, cultivating both body and spirit to prevent diseases and protect the brain, which enables the elderly to have a healthy mind and body, a sense of happiness and fulfillment, and to age gracefully. Simultaneously, advocating for tranquility is also called " respect" for relaxation, following nature to understand constant changes, and improving one′s ability to think positively in old age, in order to expand ideas for the protection of elderly brain health.

Objective:To describe the clinical manifestations, genetic mutation site, diagnosis, and treatment of a patient with multisystem proteinopathy type 1 (MSP1) caused by valosin-containing protein ( VCP) gene mutation, and to improve clinicians′ understanding of this disease. Methods:A retrospective analysis was performed on clinical and genetic data from a confirmed VCP gene missense mutation-associated MSP1 case diagnosed at the Department of Neurology, Affiliated Zhongda Hospital, School of Medicine, Southeast University in January 2024. A 12-month follow-up and systematic literature review were performed for comprehensive analysis. Results:The 53-year-old male patient presented with progressive limb weakness over 7 months. Neurological examination demonstrated tongue fasciculations, asymmetric proximal muscle weakness in all four limbs, left patellar hyperreflexia, positive right Chaddock sign, and bilateral Hoffmann signs. Electrophysiological studies demonstrated extensive neurogenic damage. Lower-limb muscle magnetic resonance imaging (MRI) showed selective fatty infiltration in specific muscle groups. Biceps brachii biopsy pathology revealed rimmed vacuoles and grouped atrophy of typeⅡfibers. Immunofluorescence confirmed aberrant aggregation of VCP within atrophic myofibers, showing co-localization with p62 and transactive response DNA binding protein 43 (TDP-43). Whole-genome sequencing identified a heterozygous c.463C>T (p.Arg155Cys) missense mutation in exon 5 of the VCP gene, classified as a likely pathogenic mutation according to the guidelines of the American College of Medical Genetics and Genomics and the Association for Molecular Pathology. The patient was diagnosed with MSP1 with amyotrophic lateral sclerosis and inclusion body myopathy as the main clinical manifestation based on clinical manifestations, electrophysiology, imaging, histopathology, and genetic findings. After 12 months of riluzole therapy, disease progression remained relatively slow. Literature review identified 67 relevant articles, revealing 87 VCP mutation genotypes and 19 clinical phenotypes. Conclusions:MSP1 is a genetically and phenotypically heterogeneous spectrum of multisystem degenerative disorders. This case represents the first reported VCP-related MSP1 in China, characterized by amyotrophic lateral sclerosis combined with inclusion body myopathy. Riluzole treatment demonstrates slowed disease progression over 1 year.

Objective:To determine the prevalence, risk factors, and longitudinal associations of loneliness during mid- to late pregnancy with anxiety and depressive symptoms in late pregnancy.Methods:In this prospective cohort study, 1 107 pregnant women at 24-28 weeks' gestation were enrolled between June 2021 and December 2022. Psychological status was assessed during mid-pregnancy (24-28 weeks) and late pregnancy (≥32 weeks) using standardized electronic questionnaires, including the Revised University of California Los Angeles Loneliness Scale (UCLA) Loneliness Scale-Short Form (Cronbach's α=0.82), Patient Health Questionnaire-9 ( α=0.86), and Generalized Anxiety Disorder-7 ( α=0.88). Multivariate logistic regression identified independent risk factors for loneliness. Cross-lagged path models analyzed the longitudinal predictions between loneliness and anxiety/depressive symptoms. Results:The prevalence of loneliness decreased significantly from 10.8% (120/1 107) in mid-pregnancy to 4.8% (37/777) in late pregnancy ( χ2=21.81, P<0.001). Multivariate analysis identified independent risk factors for loneliness: age <30 years ( OR=1.70, 95% CI: 1.15-2.50), annual household income <50 000 CNY ( OR=2.53, 95% CI: 1.28-5.02), unemployment during pregnancy ( OR=1.57, 95% CI: 1.03-2.39), history of alcohol consumption ( OR=1.63, 95% CI: 1.03-2.56), and the presence of mid-pregnancy depressive ( OR=2.76, 95% CI: 1.51-5.04) and anxiety symptoms ( OR=1.65, 95% CI: 1.01-2.71) (all P<0.05). Cross-lagged path models indicated bidirectional associations between loneliness and both anxiety ( β=0.32, P<0.01) and depressive symptoms ( β=0.28, P<0.01). However, the predictive effect of loneliness on subsequent depressive and anxiety symptoms ( β=0.28-0.32) was substantially stronger than the reverse prediction (mid-pregnancy anxiety on late-pregnancy loneliness: β=0.12; mid-pregnancy depression on late-pregnancy loneliness: β=0.11). Loneliness demonstrated high temporal stability (autoregressive effects β=0.29-0.32). Conclusion:Loneliness in mid-pregnancy exhibits a symmetric bidirectional association with anxiety and depressive symptoms in late pregnancy, suggesting it may be a core driver in the development of these emotional symptoms. Younger maternal age (<30 years), low household income (<50 000 CNY/year), unemployment during pregnancy, and a history of alcohol consumption were associated with a higher risk of loneliness and should be prioritized for psychological screening and intervention.

Objective To investigate the effect of the rs3765467 polymorphism of glucagon-like peptide-1 receptor(GLP-1R)gene on the efficacy of Liraglutide(Lir)in patients with type 2 diabetes mellitus(T2DM)and metabolic associated fatty liver disease(MAFLD).Methods A total of 281 patients with T2DM from May 2022 to May 2023 were selected,including 125 patients with simple T2DM(T2DM group)and 156 patients with T2DM combined with MAFLD(T2DM+MAFLD group).120 healthy individuals during the same period were selected as the control(NC)group.The related indexes of glucose and lipid metabolism were detected.The polymorphism of GLP-1R gene rs3765467 was detected.Results BMI,FPG,HbA1c,HOMA-IR and TG in each group increased in turn(P<0.05),while the distribution frequency of genotype GG and allele G decreased in turn(P<0.05).TC and LDL-C in T2DM and T2DM+MAFLD groups were higher than those in NC group(P<0.05).TC and TG levels in genotype GA/AA patients were significantly higher than those in genotype GG patients(P<0.05).Compared with before treatment,the levels of BMI,FPG,HbA1c,HOMA-IR,TC,TG and LDL-C in T2DM patients with MAFLD were significantly decreased after Lir treatment(P<0.05).There was no significant difference in BMI and related indexes of glucose and lipid metabolism in GG and GA/AA patients before and after Lir treatment(P>0.05).Conclusions The distribution frequency of GG and G allele at rs3765467 of GLP-1R gene is reduced in T2DM patients with MAFLD.The carrying of allele A was associated with increased TC and TG levels,but did not affect the efficacy of Lir in reducing weight and improving glycolipid metabolism.
