Objective To explore the relationship between baseline urinary protein levels and the onset of chronic obstructive pulmonary disease (COPD). Methods A questionnaire survey, blood and urine sample collection, physical examination, and pulmonary function test were conducted among permanent residents over 40 years old in Pudong New Area, Shanghai. The subjects were divided into four groups based on the baseline urine albumin-to-creatinine ratio (ACR) quartiles (0~1.65 mg/g, 1.65~4.89 mg/g, 4.89~10.78 mg/g, and ≥10.78 mg/g). Cox regression analysis was used to explore the relationship between ACR levels and the incidence of COPD in middle-aged and elderly people. Results Among the 3 105 subjects, the median follow-up time was 3.212 years (P25~P75：3.102~3.473). 116 new cases of COPD were observed, with an incidence density of 10.423 per 1000 person-years. The incidence densities for COPD at four ACR levels were 7.922 per 1 000 person-years, 8.300 per 1 000 person-years , 11.419 per 1 000 person-years, and 13.843 per 1 000 person-years, respectively. Cox regression analysis revealed that as the ACR level increased, there was a rising trend in the incidence rate of COPD (χ²=4.396, P=0.036). After adjusting for gender, age, education level, occupational exposure to dust, history of childhood pneumonia, smoking, family history of COPD, central obesity, and hypertension, the risk of developing COPD was 2.499 times higher (95% CI: 1.460~4.276) for ACR levels ≥10.78 mg/g compared to the reference group with a baseline ACR level of 0~1.65 mg/g. Conclusion Elevated ACR levels in middle-aged and elderly population may increase the risk of COPD, and early monitoring of urine protein levels is beneficial for COPD prevention.

Objective:To examine the risk factors and predictive value of depression following mild acute ischemic stroke in elderly individuals.The aim is to enhance early identification and intervention, ultimately leading to improved prognosis.Methods:A case-control study was conducted on 988 elderly patients with mild acute ischemic stroke.The study collected general population and social data, as well as clinical laboratory data such as blood glucose, blood lipids, and AD7C-NTP in urine.Additionally, the patients underwent assessments using the Montreal Cognitive Assessment Scale(MoCA), National Institutes of Health Stroke Scale(NHISS), Barthel index(BI), Hamilton Anxiety Scale(HAMA), and Hamilton Depression Scale(HAMD).Based on the HAMD depression scale score, the patients were divided into a nopost-stooke depression(NPSD)group and a post-stooke depression(PSD)group.The study then analyzed the related risk factors and predictive value of PSD.Results:A total of 988 patients were eligible for inclusion, with 132 being excluded and 856 being included.The NPSD and PSD groups showed significant differences in age, hypertension, smoking history, education level, and stroke history(all P<0.05).Regarding clinical data, there were statistically significant differences between the two groups in total cholesterol(TC), triacylglycerol(TG), HDL, urinary AD7C-NTP, MoCA, and HAMA scores(all P<0.05).The results of the multi-factor logistic regression analysis revealed that gender( OR=1.975, 95% CI: 1.223-3.190, P=0.005), stroke history( OR=1.352, 95% CI: 0.877-2.086, P=0.042), and HAMA score( OR=1.216, 95% CI: 0.932-1.526, P=0.043)were identified as independent risk factors for post-stroke depression in the elderly.Conversely, MoCA score( OR=0.873, 95% CI: 0.814-0.937, P<0.001)was found to be an independent protective factor.Furthermore, the ROC curve analysis demonstrated that the HAMA score(AUC=0.892, sensitivity: 0.721, specificity: 0.854, cut-off value: 9.5)exhibited significant predictive value, while the other indexes had limited predictive value. Conclusions:Gender, stroke history, and HAMA score have been identified as potential independent risk factors for post-stroke depression(PSD)in the elderly, while MoCA score may serve as an independent protective factor.Notably, HAMA score demonstrates a strong predictive ability for PSD.Early identification of these factors and timely intervention could significantly contribute to improving prognosis.

Objective:To observe the effects of kidney-tonifying and mind-calming acupuncture therapy on sleep,mood,sex hormone levels,and traditional Chinese medicine(TCM)symptoms in patients with perimenopausal insomnia(PMI). Methods:A total of 90 patients with PMI were randomly divided into a treatment group and a control group,with 45 cases in each group.Patients in the treatment group were treated with acupuncture at Shenshu(BL23),Taixi(KI3),Baihui(GV20),and Anmian(Extra).The control group was treated with sham acupuncture.Both groups were treated 3 times a week for 4 weeks.Pittsburgh sleep quality index(PSQI)and insomnia severity index(ISI)were used to evaluate the sleep quality of the subjects before treatment,after treatment,and 1 month after treatment(follow-up).Beck depression inventory(BDI)and Beck anxiety inventory(BAI)were used to evaluate the depression and anxiety of the subjects before treatment,after treatment,and at 1-month follow-up.The TCM symptom scale was used to evaluate the TCM symptoms of the subjects before treatment,after treatment,and 1 month after treatment.Serum levels of estradiol(E2),follicle-stimulating hormone(FSH),and luteinizing hormone(LH)were measured before and after treatment. Results:During the study,2 cases dropped out of the treatment group,and no cases dropped out of the control group.The PSQI scores of the treatment group were significantly lower after treatment and at 1-month follow-up compared with those before treatment(P<0.05),and the difference was statistically significant compared with that of the control group(P<0.05).In the control group,the PSQI score was significantly lower after treatment compared with before treatment(P<0.05),and the difference was not statistically significant at 1-month follow-up compared with before treatment(P>0.05).Compared with the pre-treatment,the ISI,BDI,BAI,and TCM symptom scale scores of the treatment group were lower after treatment and at 1-month follow-up(P<0.05),and the differences with the control group at the same time point were statistically significant(P<0.05).The differences in ISI,BDI,BAI,and TCM symptom scale scores of the control group before treatment,after treatment,and at 1-month follow-up were not statistically significant(P>0.05).After treatment,the serum E2 level in the treatment group was significantly higher than that before treatment(P<0.05),and the difference with the control group was statistically significant(P<0.05).The difference in the serum E2 level before and after treatment in the control group was not statistically significant(P>0.05).The differences in the serum FSH and LH levels between before and after treatment were not statistically significant in either group of subjects(P>0.05). Conclusion:Kidney-tonifying and mind-calming acupuncture therapy can improve sleep quality,relieve anxiety and depression,delay the decrease of serum E2 level,and improve related TCM symptoms in patients with PMI.

Objective:To explore the application of virtual augmented reality (AR) technology combined with transcranial Doppler ultrasound (TCD) in nursing teaching of cerebrovascular diseases.Methods:Eighty-six nursing students who interned in the Department of Neurology of The First Affiliated Hospital of Army Medical University from January 2021 to November 2022 were assigned into control group (students of grade 2021) and research group (students of grade 2022). The control group received traditional teaching with AR technology about the anatomy of the cerebral arterial circle, its composition, and adjacent structures. The research group was given AR-assisted teaching combined with TCD-based demonstration and interpretation. At the end of internship, the assessment scores, satisfaction with teaching, clinical decision-making ability, self-learning ability, and problem-solving ability were compared between the two groups. SPSS 23.0 was used to perform the non-parametric test, t test, and chi-square test. Results:The theoretical, practical, and comprehensive ability assessment scores of the research group [90 (89, 96), 95 (90, 96), and 93 (90, 96), respectively] were significantly higher than those of the control group [89 (87, 91), 90 (89, 92), and 91 (89, 94), respectively]. In terms of satisfaction with teaching effects, teaching methods, teaching content, and teaching style, the scores of the research group [16 (15, 18), (5.98±0.91), (3.38±0.52), and 13 (11, 14), respectively] were significantly higher than those of the control group [14 (13, 16), (4.23±0.65), (2.37±0.36), and 13 (10, 14 ), respectively]. The research group showed significantly better independent learning abilities than the control group in information seeking [(4.66±0.71) vs. (4.00±0.61)] and solution seeking [(4.43±0.68) vs. (4.41±0.67)], with no significant differences in the other dimensions between the two groups. The research group was significantly superior to the control group in all problem-solving dimensions: positive orientation [12 (10, 12) vs. 10 (9, 11)], rationality [26 (23, 28) vs. 21 (21, 24)], negative orientation [15 (13, 20) vs. 20 (17, 20)], avoidance style [17 (15, 18) vs. 19 (17, 20)], and impulsivity/neglect style [16 (15, 18) vs. 18 (16, 20)]. For rounds assessment, the research group showed significantly higher scores than the control group in all the items except " communication with patients" [(9.21±0.39) vs. (9.04±0.53)] and "patient satisfaction with nursing students" [(8.92±0.53) vs. (8.73±0.56)].Conclusions:The teaching method based on AR combined with TCD can improve nursing students' knowledge of cerebrovascular diseases, clinical nursing ability, and satisfaction with teaching.

Objective:To study the mechanism of Carthami Flos- Paeoniae Raidx Alba herb pair in the treatment of migraine based on network pharmacology and experimental verification. Methods:TCMSP was queried to screen the drug components of Carthami Flos and Paeoniae Raidx Alba, and Swiss Target Prediction was used to predict the drug components. GeneCards was conducted to obtain disease targets for migraine, and Venny 2.1 was used to obtain intersection targets. PPI analysis with STRING and network diagrams with Cytoscape, GO and KEGG analysis with Metascape. The "drug-target-pathway" network was constructed by Cytoscape software. The migraine rat model was established by the nitroglycerin method, and the rats were divided into a model group and an observation group (5 rats in each group) according to the random number table method. The observation group was given 1.8 g/kg Carthami Flos- Paeoniae Raidx Alba solution, while the model group was given 0.9% sodium chloride solution, once a day, for 2 weeks. Symptom improvement was evaluated after treatment, and the core target of serum V-Rel endotheloproliferative virus oncogene homology A (RELA), protein kinase B1 (Akt1), mitogen-activated protein kinase 1 (MAPK1), tumor necrosis factor (TNF), cysteine aspartic protease-3 (Caspase-3), and interleukin-6 (IL-6) expression was detected. Results:It was found that 24 active ingredients in Carthami Flos- Paeoniae Raidx Alba herb pair directly act on 178 disease targets through multiple pathways to treat migraine. Among them, 6-hydroxykaempferol, beta-carotene, baicalin, beta-sitosterol and kaempferol were the core components. RELA, Akt1, MAPK1, TNF, Caspase-3, IL-6 were critical targets. The GO analysis showed 85 cellular component (CC), 228 biological process (BP) and 119 molecular function (MF). Enrichment analysis of KEGG signaling pathway suggested that Carthami Flos- Paeoniae Raidx Alba herb pair was mainly involved in advanced glycosylated end-product (AGE)-advanced glycosylated end-product receptor (RAGE), hypoxia-inducing factor-1 (HIF-1), phosphatidylinositol 3-kinase (PI3K)-protein kinase B (Akt) and MAPK signaling pathways. The experimental results showed that compared with the model group, the scores of Carthami Flos- Paeoniae Raidx Alba herb pair decreased at 0 ~ 30, 60 ~ 90, and 120 ~ 150 min (all P < 0.01), and the pain threshold of mechanical and thermal stimuli increased (all P < 0.01). Serum levels of RELA, Akt1, MAPK1, TNF, Caspase-3, and IL-6 were decreased (all P < 0.01). Conclusions:Carthami Flos- Paeoniae Raidx Alba herb pair can treat migraine by regulating RELA, Akt1, MAPK1, TNF, Caspase-3 and IL-6 signaling pathways including IL-17, TNF, Toll receptor, T cell receptor, AGE-RAGE, HIF-1, PI3K/Akt and MAPK.

Objective:To explore the risk factors for cognitive impairment 3 months after an ischemic stroke and their predictive value.Methods:A retrospective case-control study considered the records of 856 elderly patients who had survived an ischemic stroke. All had been evaluated using the Montreal Cognitive Assessment scale (MoCA). They were divided according to their MoCA scores into a group without cognitive impairment (the PSNCI group) and an impaired (PSCI) group. The subjects′ demographic and clinical laboratory data were compiled. All had been assessed using the National Institutes of Health stroke scale (NIHSS), the Barthel Index (BI), and the Hamilton depression scale (HAMD). Univariate and multivariate logistic regressions were evaluated and a receiver operator characteristics (ROC) curve was computed.Results:There were significant differences between the two groups in terms of gender distribution, age, hypertension and heart disease history, family history of dementia and education level. Moreover, significant differences were observed in the groups′ average total cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL), urinary neurofilament protein (AD7c-NTP), NIHSS scores, BIs and ADL scores. Logistic regression showed that a history of heart disease, urinary AD7C-NTP level and HAMD score were significant independent predictors of cognitive impairment 3 months after a stroke. A high BI was an independent protective factor. The area under the ROC curve for urinary AD7C-NTP was the largest (0.875) and had significant predictive value with a cut-off value of 2.43, sensitivity of 0.94 and specificity of 0.75.Conclusion:Age, sex, education, smoking, drinking, body mass index, a history of heart disease or stroke, a family history of dementia and elevated AD7C-NTP, TC or TG are risk factors for cognitive impairment after a stroke. A high BI suggests a better prognosis. Urinary AD7c-NTP is a useful predictor of PSCI 3 months after a stroke.

Trace amines(TAs)are metabolically related to catecholamine and associated with cancer and neuro-logical disorders.Comprehensive measurement of TAs is essential for understanding pathological pro-cesses and providing proper drug intervention.However,the trace amounts and chemical instability of TAs challenge quantification.Here,diisopropyl phosphite coupled with chip two-dimensional(2D)liquid chromatography tandem triple-quadrupole mass spectrometry(LC-QQQ/MS)was developed to simul-taneously determine TAs and associated metabolites.The results showed that the sensitivities of TAs increased up to 5520 times compared with those using nonderivatized LC-QQQ/MS.This sensitive method was utilized to investigate their alterations in hepatoma cells after treatment with sorafenib.The significantly altered TAs and associated metabolites suggested that phenylalanine and tyrosine metabolic pathways were related to sorafenib treatment in Hep3B cells.This sensitive method has great potential to elucidate the mechanism and diagnose diseases considering that an increasing number of physiological functions of TAs have been discovered in recent decades.

After the cells in each group were cultured in culture medium or drug solution for 48 hours，the levels of aspartate aminotransferase（AST）and alanine aminotransferase （ALT）were detected ；the levels of glutathione （GSH），superoxide dismutase （SOD）and malondialdehyde （MDA）in cell culture medium were detected ；reactive oxygen species （ROS）level and mitochondrial membrane potential in cells were detected ；mRNA and protein expressions of glucose-regulated protein 78（GRP-78）and protein kinase R-like endoplasmic reticulum kinase （PERK）were detected. RESULTS Compared with blank control group ，the levels of AST，ALT，MDA and ROS ，mRNA and protein expressions of GRP- 78 and PERK were increased significantly in P. corylifolia model group （P＜0.05 or P＜0.01）；while GSH and SOD levels ，mitochondrial membrane potential were decreased significantly （P＜0.05 or P＜0.01）. Compared with P. corylifolia model group ，above indexes of P. corylifolia -S. chinensis low-dose， medium-dose and high-dose groups were all improved significantly （P＜0.05 or P＜0.01）. CONCLUSIONS The compatibility of P. corylifolia -S. chinensis can alleviate P. corylifolia -induced oxidative damage and endoplasmic reticulum stress of L 02 cells.

Objective:To analyze the survival benefits and treatment related toxic effects of simultaneous integrated boost intensity-modulated radiotherapy (SIB-RT) for non-operative esophageal squamous cell carcinoma patients.Methods:The data of 2 132 ESCC patients who were not suitable for surgery or rejected operation, and underwent radical radiotherapy from 2002 to 2016 in 10 hospitals of Jing-Jin-Ji Esophageal and Esophagogastric Cancer Radiotherapy Oncology Group (3JECROG) were analyzed. Among them, 518 (24.3%) cases underwent SIB (SIB group) and 1 614 (75.7%) cases did not receive SIB (No-SIB group). The two groups were matched with 1∶2 according to propensity score matching (PSM) method (caliper value=0.02). After PSM, 515 patients in SIB group and 977 patients in No-SIB group were enrolled. Prognosis and treatment related adverse effects of these two groups were compared and the independent prognostic factor were analyzed.Results:The median follow-up time was 61.7 months. Prior to PSM, the 1-, 3-, and 5-years overall survival (OS) rates of SIB group were 72.2%, 42.8%, 35.5%, while of No-SIB group were 74.3%, 41.4%, 31.9%, respectively ( P=0.549). After PSM, the 1-, 3-, and 5-years OS rates of the two groups were 72.5%, 43.4%, 36.4% and 75.3%, 41.7%, 31.6%, respectively ( P=0.690). The univariate survival analysis of samples after PSM showed that the lesion location, length, T stage, N stage, TNM stage, simultaneous chemoradiotherapy, gross tumor volume (GTV) and underwent SIB-RT or not were significantly associated with the prognosis of advanced esophageal carcinoma patients who underwent radical radiotherapy ( P<0.05). Cox model multivariate regression analysis showed lesion location, TNM stage, GTV and simultaneous chemoradiotherapy were independent prognostic factors of advanced esophageal carcinoma patients who underwent radical radiotherapy ( P<0.05). Stratified analysis showed that, in the patients whose GTV volume≤50 cm 3, the median survival time of SIB and No-SIB group was 34.7 and 30.3 months ( P=0.155), respectively. In the patients whose GTV volume>50 cm 3, the median survival time of SIB and No-SIB group was 16.1 and 20.1 months ( P=0.218). The incidence of radiation esophagitis and radiation pneumonitis above Grade 3 in SIB group were 4.3% and 2.5%, significantly lower than 13.1% and 11% of No-SIB group ( P<0.001). Conclusions:The survival benefit of SIB-RT in patients with locally advanced esophageal carcinoma is not inferior to non-SIB-RT, but without more adverse reactions, and shortens the treatment time. SIB-RT can be used as one option of the radical radiotherapy for locally advanced esophageal cancer.
