OBJECTIVE To investigate the prevalence and influencing factors of potentially inappropriate medication （PIM） among the elderly in nursing homes in Urumqi based on three PIM screening tools， and to compare the applicability of different tools. METHODS A cross-sectional study design was adopted. Elderly individuals from six nursing homes in Urumqi were selected as the research subjects from May 2021 to September 2023. Demographic characteristics， disease burden and medication records of the elderly were collected. PIM screening was performed using the Chinese PIM criteria （2024 edition）， the American Geriatrics Society （AGS） Beers criteria （2023 edition）， and the Screening Tool of Older Person’S Prescriptions（STOPP）/Screening Tool to Alert to Right Treatment（START） （2023 edition）. Fleiss’s Kappa test was used to assess the consistency among the three screening tools， and multivariate Logistic regression was used to analyze the influencing factors of PIM. RESULTS The prevalence of PIM screened by the Chinese PIM criteria was 47.4% （323/682）， by the AGS Beers criteria was 43.4% （296/682）， and by the STOPP criteria was 50.9% （347/682）. The consistency among the three screening tools was low （Fleiss’s Kappa＝0.12， P ＜0.001）. Multivariate Logistic regression analysis showed that all three screening tools indicated that polypharmacy， aspirin use and psychotropic drug use were independent risk factors for PIM among elderly in nursing houses （all OR＞1， P ＜0.05）. CONCLUSIONS The prevalence of PIM among the elderly in nursing homes in Urumqi is relatively high. Polypharmacy， aspirin use and psychotropic drug use are common independent risk factors for PIM. There are differences in screening results among the three tools with low consistency. The Chinese PIM criteria can serve as a first-line tool for PIM screening in nursing homes.

Objective: To explore the relationship of non suicidal self injury (NSSI) with anhedonia and dysfunctional attitudes in children and adolescents with depression, in order to provide a basis for the prevention and treatment of NSSI patients. Methods: A total of 157 children and adolescents with depression admitted to Wuhan Psychosomatic Hospital from February 2023 to February 2025 were enrolled and divided into an NSSI group(36 cases) and a non NSSI group (121 cases), according to the diagnostic criteria of Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. The Childhood Trauma Questionnaire-Short Form (CTQ-SF) Chinese version of Dimensional Anhedonia Rating Scale (DARS) and the Chinese version of Dysfunctional Attitude Scale-A (DAS-A) were utilized to evaluate the childhood trauma, anhedonia and dysfunctional attitude scores, respectively. Spearman correlation analysis was used to analyze the relationship between NSSI and DARS, DAS-A scores. Multivariable Logistic regression analysis was performed to examine the relationship of NSSI with childhood trauma, DARS and DAS-A scores in children and adolescents with depression. Results: The incidence rate of NSSI of children and adolescents was 22.93%. The proportions of childhood trauma and major depression in NSSI group (58.33% and 61.11%) were higher than those in non NSSI group (35.54% and 41.32%), with statistical differences ( χ 2=5.79, 4.38, both P <0.05). The total score of DAS-A with (188.41±35.27) in NSSI group was higher than in non NSSI group (140.21±30.62), while the scores across DARS dimensions (hobbies, food/drinks, social activities, sensory experiences) and total DARS score (5.37±1.22, 6.96±1.48, 7.13±2.02, 12.06±3.15, 30.19±7.43) were significantly lower than those in the non NSSI group (9.04±2.25, 10.16±2.43, 10.97±2.62, 14.51±4.08, 44.16±12.51),with statistical differences ( t =8.00, -9.37, -7.49, -8.10, -3.32, -6.37, all P <0.01). The NSSI in children and adolescents with depression was positively correlated with childhood trauma, severity of depression and DAS-A total score, and negatively correlated with DARS total score ( r =0.21, 0.63, 0.54, -0.50, all P <0.05). After adjusting for severity of depression, multivariate Logistic regression analysis revealed that childhood trauma, total scores of DARS and DAS-A were all correlated factors for the occurrence of NSSI in children and adolescents with depression ( OR =1.52, 1.48, 1.96, all P <0.05). Conclusion The risk of NSSI in children and adolescents with depression is relatively high, and NSSI is closely related to anhedonia, dysfunctional attitudes and childhood trauma.

Alzheimer’s disease (AD) is a central neurodegenerative disease characterized by progressive cognitive decline and memory impairment in clinical. Currently, there are no effective treatments for AD. In recent years, a variety of therapeutic approaches from different perspectives have been explored to treat AD. Although the drug therapies targeted at the clearance of amyloid β-protein (Aβ) had made a breakthrough in clinical trials, there were associated with adverse events. Neuroinflammation plays a crucial role in the onset and progression of AD. Continuous neuroinflammatory was considered to be the third major pathological feature of AD, which could promote the formation of extracellular amyloid plaques and intracellular neurofibrillary tangles. At the same time, these toxic substances could accelerate the development of neuroinflammation, form a vicious cycle, and exacerbate disease progression. Reducing neuroinflammation could break the feedback loop pattern between neuroinflammation, Aβ plaque deposition and Tau tangles, which might be an effective therapeutic strategy for treating AD. Traditional Chinese herbs such as Polygonum multiflorum and Curcuma were utilized in the treatment of AD due to their ability to mitigate neuroinflammation. Non-steroidal anti-inflammatory drugs such as ibuprofen and indomethacin had been shown to reduce the level of inflammasomes in the body, and taking these drugs was associated with a low incidence of AD. Biosynthetic nanomaterials loaded with oxytocin were demonstrated to have the capability to anti-inflammatory and penetrate the blood-brain barrier effectively, and they played an anti-inflammatory role via sustained-releasing oxytocin in the brain. Transplantation of mesenchymal stem cells could reduce neuroinflammation and inhibit the activation of microglia. The secretion of mesenchymal stem cells could not only improve neuroinflammation, but also exert a multi-target comprehensive therapeutic effect, making it potentially more suitable for the treatment of AD. Enhancing the level of TREM2 in microglial cells using gene editing technologies, or application of TREM2 antibodies such as Ab-T1, hT2AB could improve microglial cell function and reduce the level of neuroinflammation, which might be a potential treatment for AD. Probiotic therapy, fecal flora transplantation, antibiotic therapy, and dietary intervention could reshape the composition of the gut microbiota and alleviate neuroinflammation through the gut-brain axis. However, the drugs of sodium oligomannose remain controversial. Both exercise intervention and electromagnetic intervention had the potential to attenuate neuroinflammation, thereby delaying AD process. This article focuses on the role of drug therapy, gene therapy, stem cell therapy, gut microbiota therapy, exercise intervention, and brain stimulation in improving neuroinflammation in recent years, aiming to provide a novel insight for the treatment of AD by intervening neuroinflammation in the future.

Objective To investigate the effect of heated povidone iodine solution on pain intensity and ulcer healing in patients with chronic venous leg ulcer after debridement and dressing change.Methods A total of 58 patients with chronic venous leg ulcer who first visited outpatients and wards of Department of Cardiovascular Surgery,Department of Burns and Department of Plastic Surgery of The First Affiliated Hospital of Naval Medical University from Jun.1,2023,to Jun.1,2024 were enrolled and randomly assigned to heated group(using 38 ℃ povidone iodine solution for debridement and flushing,n=29)or normal group(using 24 ℃ povidone iodine solution for debridement and flushing,n=29).The general baseline data of the 2 groups were compared,the pain intensity and wound bed temperature before and after debridement and dressing change were evaluated,and the change of pressure ulcer scale score for healing during the observation period and ulcer healing rate were observed.Results There were no significant differences between the 2 groups in age,gender,smoking,body mass index,whether the ulcer exudates,infection,duration of ulcer,ulcer area,pressure ulcer scale score for healing or analgesic use within 24 h(all P＞0.05).There was no significant difference in pain intensity between the 2 groups before or after dressing change and debridement(both P＞0.05).The pain intensity during debridement in the heated group was lower than that in the normal group(P＜0.05).There was no significant difference in the temperature of wound bed before flushing between the 2 groups(P＞0.05).The temperature of wound bed in the heated group was significantly higher than that in the normal group immediately after flushing and at the end of debridement and dressing change(P＜0.01,P＜0.05).The pressure ulcer scale score for healing in the heated group showed a trend of being lower than that in the normal group during the observation period,and the ulcer healing rate was significantly higher than that in the normal group(P=0.033,hazard ratio=0.452,95％confidence interval 0.217-0.941).Conclusion In patients with chronic venous leg ulcer,the use of heated povidone iodine solution can reduce the pain intensity during dressing change and debridement,maintain the stability of wound bed temperature,and promote the healing of ulcer.

Objective: To determine the clinical efficacy and mechanism of Piwei Peiyuan Pill (PPP) combined with moxibustion for treating patients with chronic atrophic gastritis (CAG) with spleen and stomach weakness syndrome. Methods: Ninety-six CAG patients with spleen and stomach weakness syndrome who met the inclusion and exclusion criteria were enrolled at the Department of Spleen and Stomach Diseases of the Second Affiliated Hospital of Anhui University of Chinese Medicine from June 2022 to December 2023. The patients were randomly divided into a control, a Chinese medicine, and a combined group using a random number table method, with 32 cases in each group (two cases per group were excluded). The control group was treated with rabeprazole combined with folic acid tablets (both thrice daily), the Chinese medicine group was treated with PPP (8 g, thrice daily), and the combined group was treated with moxa stick moxibustion (once daily) on the basis of the Chinese medicine group for 12 consecutive weeks. Gastric mucosa atrophy in the three groups was observed before and after treatment. The gastric mucosal pathological score was evaluated. The Patient Reported Outcome (PRO) scale was used to evaluate the patients′ physical and mental health status and quality of life.An enzyme-linked immunosorbent assay was used to detect serum tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-4, IL-10, IL-37, and transforming growth factor (TGF)-β levels in each group. Real-time fluorescence PCR was used to detect the relative expression levels of signal transducer and activator of transcription 3 (STAT3) and mammalian target of rapamycin (mTOR) mRNA in each group. Western blotting was used to detect the relative expression levels of proteins related to the STAT3/mTOR signaling pathway, and the adverse drug reactions and events were recorded and compared. Results: There was no statistical difference in age, gender, disease duration, family history of gastrointestinal tumors, alcohol consumption history, and body mass index among the three groups of patients.The total therapeutic efficacy rates of the control, Chinese medicine, and combined groups in treating gastric mucosal atrophy were 66.67% (20/30), 86.67% (26/30), and 90.00% (27/30), respectively (P<0.05). Compared to before treatment, the pathological and PRO scale scores of gastric mucosa in each group decreased after treatment, and TNF-α, IL-1β, IL-37, and TGF-β levels decreased. The relative STAT3 and mTOR mRNA expression levels, as well as the relative STAT3, p-STAT3, mTOR, and p-mTOR protein expression levels decreased (P<0.05), whereas the IL-4 and IL-10 levels increased (P<0.05). After treatment, compared to the control group, the pathological score of gastric mucosa, PRO scale score, TNF-α, IL-1β, IL-37, TGF-β content, relative STAT3 and mTOR mRNA expression levels, and relative STAT3, p-STAT3, mTOR, and p-mTOR protein expression levels in the Chinese medicine and combined groups after treatment were reduced (P<0.05), whereas the IL-4 and IL-10 levels increased (P<0.05). After treatment, compared to the Chinese medicine group, the combined group showed a decrease in relative STAT3, mTOR mRNA expression levels, and STAT3, p-STAT3, mTOR, and p-mTOR protein expression levels (P<0.05). Conclusion The combination of PPP and moxibustion may regulate the inflammatory mechanism of the body by inhibiting the abnormal activation of the STAT3/mTOR signaling pathway, upregulating related anti-inflammatory factor levels, downregulating pro-inflammatory factor expression, and increasing related repair factor expression, thereby promoting the recovery of atrophic gastric mucosa, reducing discomfort symptoms, and improving the physical and mental state of CAG patients with spleen and stomach weakness syndrome.

Objective: To explore the relationship between stigma and mental resilience in adolescent epilepsy patients and associated factors, so as to provide reference for future psychological intervention in adolescent patients with epilepsy. Methods: A total of 295 adolescent patients with epilepsy from Wuhan Mental Health Center were enrolled as participants from February 2021 to October 2024. The stigma was evaluated by Kilifi Stigma Scale for Epilepsy (KSSE), and psychological resilience was evaluated by Connor-Davidson Resilience Scale (CD-RISC). Associated factors of stigma and psychological resilience in adolescent patients with epilepsy were analyzed by multivariate Logistic regression analysis. Results: In the adolescent patients with epilepsy, KSSE score was (10.90±4.13) points, with 138 cases (46.78%) at low level, 154 cases (52.20%) at moderate level and 3 cases (1.02%) at high level. CD-RISC score was (50.19±5.97) points, there were 170 cases (57.63%) at low level and 125 cases (42.37%) at high level. Multivariate Logistic regression analysis showed that disease course >3 years ( OR =2.22), family history of epilepsy ( OR = 4.18) , monthly family income ≤5 000 yuan ( OR =2.05), single parent family ( OR =2.46) and middle and high stigma level ( OR = 1.72) had a higher risk on low level of mental resilience ( P <0.05). The course of disease >3 years ( OR =2.20), family history of epilepsy ( OR =3.54), general seizure ( OR =2.12), monthly family income ≤5 000 yuan ( OR =2.70), low level of mental resilience ( OR =2.03) of adolescent epilepsy patients showed a high risk on moderate high level of stigma ( P <0.05). Conclusions The stigma level is higher, while psychological resilience is lower in adolescent patients with epilepsy. Clinically, targeted intervention should be implemented based on related factors such as stigma in addescent patients with epilepsy.

Diabetes mellitus (DM) is a major global health issue, with glycated hemoglobin levels serving as the gold standard for evaluating glucose level control in DM patients. However, it has limitations in reflecting glucose oscillations (i.e. glycemic variability, GV). Increasing evidence suggests that GV is closely related to the progression of diabetes complications and patient prognosis. As people realize the importance of avoiding hypoglycemia while achieving target glycated hemoglobin levels in treatment, the clinical significance of GV becomes more obvious. This article systematically reviewed the concept and connotation of GV, summarized the latest research on its role in the complications of diabetes, and revealed the biochemical and pathophysiological abnormalities caused by excessive glycemic oscillation, aiming to provide a theoretical basis for the risk warning and early intervention of DM patients.

To investigate the mechanism of Qitu Erzhi Decoction(QTEZ) in ameliorating chemotherapy-induced myelosuppression and the focus of its decomposed formulae on the effects of hematopoietic cells of the three lineages, respectively. Ultra performance liquid chromatography-quadrupole time-of-flight tandem mass spectrometry(UPLC-Q-TOF-MS) was used to identify the components of QTEZ intestinal absorption liquid and obtain the target sites, which were intersected with chemotherapy-induced myelosuppression targets collected from several databases, including OMIM, and an interaction network was established based on network pharmacology for Gene Ontology(GO) functional analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway analysis. Hematopoietic stem cells of mice were taken after intraperitoneal injection of 5-fluorouracil for myelosuppression modeling and randomly divided into the model group, Qitu Erzhi group, Astragali Radix-Angelicae Sinensis Radix group, Ligustri Lucidi Fructus-Ecliptae Herba group, Psoraleae Fructus-Cuscutae Semen group, and positive drug group, which were given the corresponding traditional Chinese medicine intestinal absorption liquid and the positive drug granulocyte colony-stimulating factor, respectively. The normal hematopoietic stem cells were taken as the control group and were given the intervention of normal saline. The proliferation of hematopoietic progenitor cells of three lineages was observed by flow cytometry, and the cell cycle and colony formation assay were observed. Western blot was used to verify the effect of QTEZ on the pathway proteins including phosphoinositide 3-kinase(PI3K), phosphorylated PI3K(p-PI3K), protein kinase B(AKT), and phosphorylated AKT(p-AKT). RT-qPCR and Western blot were used to detect the effects of QTEZ on cell cycle-related targets such as CDK inhibitor 1(P21), cyclin D1(CCND1), and cyclin-dependent kinase 4(CDK4). The results showed that a total of 158 components were identified by QTEZ, and 375 component and disease intersecting targets were obtained, 21 core components and 40 core targets were obtained after constructing the network, and GO and KEGG enrichment showed signaling pathways such as PI3K/AKT. QTEZ and its decomposed formulae could promote the 5-fluorouracil-blocked cell cycle to resume operation, and all of them had different degrees of restoration effects on the set of colonies, among which QTEZ had the best restoration effect, and the Astragali Radix-Angelicae Sinensis Radix group had a focused effect on colony forming unit-erythrocyte. Western blot results indicated that there was no significant difference in the expression levels of pathway proteins among the groups. RT-qPCR and Western blot results showed that QTEZ could down-regulate P21 and up-regulate the protein and mRNA expression of CDK4 and CCND1. In conclusion, QTEZ and its decomposed formulas can exert a protective effect on hematopoietic stem cells with 5-fluorouracil-induced myelosuppression by promoting the normal operation of the cell cycle and colony formation, and the mechanism may be related to the down-regulation of the cell cycle-related targets of P21 and the up-regulation of CDK4 and CCND1. In addition, Astragali Radix-Angelicae Sinensis Radix can have a targeted protective effect on erythrocytes.

Objective:To evaluate the association between heatwaves and fall-related mortality.Methods:A total of 61 421 fall-related mortality from 2013 to 2022 in 7 provinces of China were included in a time-stratified case-crossover design, with daily meteorological data derived from the fifth generation European Reanalysis dataset produced by the European Centre for Medium-Range Weather Forecasts. Conditional logistic regression chimeric distributed lag nonlinear model was used to analyze the association between heatwaves and fall-related mortality and stratified analysis was conducted according to gender and age.Results:Heatwaves were associated with an increased risk of fall-related morality. The risk of fall-related mortality during heatwaves was higher than during non-heatwave periods ( OR=1.11, 95% CI: 1.05-1.18). The attributable fraction of fall-related motality due to heatwaves was 10.25% (95% CI: 4.49%-15.36%). For each 1 ℃ increase above the heatwave threshold, the risk of fall-related mortality increased by 34% ( OR=1.34, 95% CI: 1.02-1.76). The effect of heatwave duration on fall-related mortality was not statistically significant. Stratified analyses indicated that women experienced a higher risk of fall-related mortality during heatwaves ( OR=1.13, 95% CI: 1.04-1.22) compared to man ( OR=1.10, 95% CI: 1.04-1.17). Conclusions:Heatwave increases the risk of fall-related mortality, and the intensity of heatwaves modify this risk. Women are vulnerable populations.

Objective Zinc finger protein 335 (Zfp335) plays a crucial role in the early development of thymic T cells and the differentiation of peripheral T cell subpopulations. The objective of this study is to investigate the role and underlying mechanisms of Zfp335 in the regulation of regulatory T cell (Treg) within tumor immunity. Methods The Zfp335 gene was specifically knocked out in Treg using tamoxifen (Zfp335^fl/fl FOXP3^creERT2), and the MC38 tumor model was established. On the 7th day after tumor inoculation, tumor size was observed and measured. Tumor size was monitored and recorded daily starting from day 7 post-inoculation. On day 12, tumors were harvested, and the proportions of CD4⁺ T cells, CD8⁺ T cells, and Treg were analyzed by flow cytometry. Additionally, the mitochondrial function of effector regulatory T cell (eTreg) was assessed. Results From day 10 post-tumor inoculation, tumor volume in the Zfp335^CKO group was significantly reduced compared to that of the wild-type (WT) group. Furthermore, the infiltration of CD4⁺ and CD8⁺ T cells, along with their respective effector cells, was significantly higher in the Zfp335^CKO group than in the WT group. The proportions of CD4⁺ and CD8⁺ T cells producing interferon-gamma (IFN-γ) and tumor necrosis factor-alpha (TNF-α) were also significantly increased in the Zfp335^CKO group compared to that of the WT group. In addition, the percentage of CD8⁺ T cells secreting granzyme B (GzmB) was significantly higher in the Zfp335^CKO group than that in the WT group. In contrast, the proportion of Treg and inducible T cell co-stimulator (ICOS)⁺ Treg in the Zfp335^CKO group was significantly lower than that in the WT group. Finally, the expression level of Mitotracker Deep Red in eTreg from the Zfp335^CKO group was significantly reduced compared to that in the WT group. Conclusion During tumorigenesis, the specific deletion of Zfp335 impairs Treg activation, which is related to decreased mitochondrial function in eTreg. In Zfp335^CKO mice. Tumors exhibit increased infiltration of effector T cells, accompanied by elevated levels of cytotoxic cytokines, ultimately enhancing resistance to tumor progression.
