Objective:To explore the correlation between abnormal vital signs (e.g., heart rate, oxygen saturation, and body temperature) and acute exacerbations in patients with chronic obstructive pulmonary disease (COPD), as well as to evaluate the clinical value of continuous monitoring via wearable devices for the early warning and intervention.Methods:A multicenter cross-sectional study enrolled 335 patients with stable chronic obstructive pulmonary disease (COPD) from 12 community health centers in Beijing and Chengdu between June 2023 and May 2024. General demographic and clinical data were collected, and each participant underwent continuous monitoring of resting heart rate, oxygen saturation, and body temperature using wearable devices for 21 days. Based on whether participants had experienced acute exacerbations requiring outpatient, emergency, or inpatient treatment within the previous year, they were categorized into the acute exacerbation group and the non-exacerbation group. Differences in physiological parameters between the acute exacerbation group and non-exacerbation group were analyzed, and contributing factors were assessed using logistic regression analysis.Results:A total of 335 patients with stable COPD were enrolled, including 252 cases (75.22%) in the acute exacerbation group and 83 cases (24.78%) in the non-acute exacerbation group. There were no statistically significant differences in age, sex distribution, comorbidities, or baseline lung function between the two groups (all P>0.05). Compared with the non-acute exacerbation group, patients in the acute exacerbation group had a faster resting heart rate((76.01 ± 7.78) beats/min vs. (72.72 ± 7.35) beats/min, t=3.126, P=0.002), a higher proportion of patients with decreased oxygen saturation (1.75% (0.97%, 3.03%) vs. 0.86% (0.44%, 1.65%), Z=11.086, P=0.001), and a higher proportion of patients with elevated body temperature (0.60% (0.39%, 1.03%) vs. 0.31% (0.17%, 0.54%), Z=7.314, P=0.007). Logistic regression analysis showed that advanced age ( OR=1.051, 95% CI: 1.023-1.080), increased heart rate ( OR=1.055, 95% CI:1.013-1.098), decreased oxygen saturation ( OR=1.197, 95% CI:1.023-1.400), and elevated body temperature ( OR=1.777, 95% CI:1.148-2.752) were positively associated factors for acute exacerbation of COPD. Conclusions:Abnormalities in physiological indicators such as heart rate, oxygen saturation, and body temperature are associated with acute exacerbations in COPD patients. Continuous monitoring using wearable devices may provide a new method for early warning and timely intervention in COPD exacerbations.

Thyroid hormone（TH）plays an important role in human development and is involved in gene and protein expression in almost all tissues，especially in the development of the central nervous system.TH requires a TH transporter to enter the cell，and three families of TH transporter proteins are known，namely monocarboxylate transporters（MCTs），organic anion transporting polypeptides（OATPs）and L-type amino acid transporter（LAT）.MCT8 has been found to be a specific TH transporter，and OATP1C1 also plays an important role.Deficiency of TH transporters may lead to different degrees of dysfunction in the nervous system and endocrine system.Currently，more studies have been conducted on MCT8 deficiency，which presents with characteristic psychomotor retardation and TH abnormalities，and there are no specific treatment options.In this paper，we summarize the research progress on clinical phenotype，pathogenic mechanism，and treatment of thyroid hormone transporter defects related diseases to provide reference for clinical research.

Objective To investigate the impact of various health education intervention strategies on the proper use of personal respiratory protective equipment (RPE) among workers exposed to dust. Methods Dust-exposed workers were recruited from 60 selected enterprises in Guangdong Province using cluster random sampling method. They were randomly allocated to the control, low-intensity intervention, and high-intensity intervention groups, with 358, 346, and 371 workers in each group, respectively. Workers in the control group received no designed intervention. Workers in the low-intensity intervention group received traditional plus mobile health education on the proper use of RPE. Workers in the high-intensity intervention group received all components of the low-intensity intervention, supplemented with peer education. The intervention lasted for six months. RPE usage was compared among the three groups of workers before and after the intervention. Results Workers in the control, low-intensity intervention, and high-intensity intervention groups showed higher rates of both RPE wearing and correct RPE wearing after the intervention than before it within their respective groups (RPE wearing rate: 94.1% vs 99.2%, 95.7% vs 100.0%, 94.6% vs 100.0%, all P<0.01; correct RPE wearing rate: 66.8% vs 91.1%, 67.3% vs 95.7%, 66.6% vs 96.5%, all P<0.01). Post-intervention correct RPE wearing rates were highest in the high-intensity intervention group, followed by the low-intensity intervention group, and the control group, with the percentage of 96.50%, 95.66% and 91.06%, respectively (P<0.01). Binary logistic regression analysis result showed that different intervention strategies affected the correct use of personal RPE among dust-exposed workers after adjusting for gender, age, and other confounding factors (P<0.05). Compared with the control group, the rates of correct RPE use increased in the low-intensity intervention group and the high-intensity intervention group (odd ratio was 2.14 and 3.01; 95% confidence interval was 1.12 - 4.10 and 1.53 - 5.91, respectively). Conclusion The implementation of traditional plus mobile health education interventions on the proper use of RPE can promote correct RPE utilization among dust-exposed workers, and integrating peer education further enhances the intervention effectiveness.

Background:Acute pancreatitis(AP)is a common disease of the digestive system,among which severe acute pancreatitis(SAP)has a high mortality rate.Finding more accurate and convenient methods for early recognition of SAP is one of the major challenges in clinical treatment.Aims:To explore the application value of the controlled attenuation parameter(CAP)of ultrasound elastography in predicting SAP.Methods:A retrospective cohort study was conducted involving 135 AP patients admitted to Jiading Branch of Shanghai General Hospital from February to October 2024.Patients were categorized into non-SAP and SAP groups according to the severity of the disease.Clinical data,local complications,laboratory indicators,and CAP were compared between the two groups.Univariate and multivariate Logistic regression analyses were used to identify independent risk factors for SAP.A SAP prediction model based on CAP was constructed according to the identified risk factors and the minimum Akaike information criterion(AIC).ROC curve and Bootstrap method were used to evaluate the efficacy of the prediction model and conduct internal validation,respectively.Results:There were statistically significant differences between the non-SAP group and SAP group in body mass index(BMI),incidence of hyperlipidemia,etiological composition,incidence of pleural and ascitic fluid,length of hospital stay,incidence of peripancreatic effusion,incidence of pancreatic necrosis,white blood cell count(WBC),D-dimer(D-D)level,blood glucose,triglyceride(TG),C-reactive protein(CRP),neutrophil count,procalcitonin(PCT),interleukin-6(IL-6),free triiodothyronine(FT3),and CAP(all P<0.05).Multivariate Logistic regression analysis showed that pancreatic necrosis(OR=13.39,95%CI:3.10-57.94,P<0.001)and CAP(OR=1.01,95%CI:1.01-1.02,P=0.038)were independent risk factors for SAP.The SAP prediction model based on CAP was formulated as:Logit(P)=-5.884+0.010×CAP+2.839×pancreatic necrosis+0.169×D-D+0.132×blood glucose+0.006×CRP.The model showed an area under the curve(AUC)of 0.834 for predicting SAP,which was superior to CAP alone(P<0.05).Internal validation indicated that the prediction model had high stability and accuracy(C-index=0.808).Conclusions:The prediction model constructed based on CAP has good clinical value for predicting SAP,providing a new perspective and tool for early identification and prognostic assessment of AP.

Objective:To explore the correlation between abnormal vital signs (e.g., heart rate, oxygen saturation, and body temperature) and acute exacerbations in patients with chronic obstructive pulmonary disease (COPD), as well as to evaluate the clinical value of continuous monitoring via wearable devices for the early warning and intervention.Methods:A multicenter cross-sectional study enrolled 335 patients with stable chronic obstructive pulmonary disease (COPD) from 12 community health centers in Beijing and Chengdu between June 2023 and May 2024. General demographic and clinical data were collected, and each participant underwent continuous monitoring of resting heart rate, oxygen saturation, and body temperature using wearable devices for 21 days. Based on whether participants had experienced acute exacerbations requiring outpatient, emergency, or inpatient treatment within the previous year, they were categorized into the acute exacerbation group and the non-exacerbation group. Differences in physiological parameters between the acute exacerbation group and non-exacerbation group were analyzed, and contributing factors were assessed using logistic regression analysis.Results:A total of 335 patients with stable COPD were enrolled, including 252 cases (75.22%) in the acute exacerbation group and 83 cases (24.78%) in the non-acute exacerbation group. There were no statistically significant differences in age, sex distribution, comorbidities, or baseline lung function between the two groups (all P>0.05).

Objective:To observe and evaluate the clinical efficacy and safety of albumin-bound paclitaxel as first-line treatment for patients with advanced pancreatic cancer in China, and to explore the prognosis-related molecules in pancreatic cancer based on next-generation sequencing (NGS) of tumor tissues.Methods:From December 2018 to December 2020, patients with locally advanced or metastatic pancreatic cancer were recruited to accept albumin-bound paclitaxel as first-line treatment in the oncology departments of 24 hospitals in East China. The primary endpoints were overall survival (OS) and treatment related adverse events, and the secondary endpoint was progression-free survival (PFS). Adverse effects were graded using Common Terminology Criteria for Adverse Events 5.0 (CTCAE 5.0). NGS sequencing on the primary or metastatic tissue samples of pancreatic cancer obtained through surgical resection or biopsy was performed.Results:This study recruited 229 patients, including 70 patients with locally advanced pancreatic cancer (LAPC) and 159 patients with metastatic pancreatic cancer (mPC). The disease control rate was 79.9% and the objective response rate is 36.3%.The common adverse effects during treatment were anaemia (159 cases), leucopenia (170 cases), neutropenia (169 cases), increased aminotransferases (110 cases), and thrombocytopenia (95 cases), and the incidence of grade 3-4 neutropenia is 12.2% (28/229). The median follow-up time was 21.2 months (95% CI: 18.5-23.1 months). The median PFS (mPFS) was 5.3 months (95% CI: 4.37-4.07 months) and the median OS (mOS) was 11.2 months (95% CI: 9.5-12.9 months). The mPFS of patients with LAPC was 7.4 months (95% CI: 6.6-11.2 months), and their mOS was 15.5 months (95% CI: 12.6-NA months). The mPFS of patients with mPC was 3.9 months (95% CI: 3.4-5.1 months), and their mOS was 9.3 months (95% CI: 8.0-10.8 months). Multivariate Cox regression analysis showed that clinical stage ( HR=1.47, 95% CI: 1.06-2.04), primary tumor site ( HR=0.64, 95% CI: 0.48-0.86), Eastern Cooperative Oncology Group Performance Status (ECOG PS) score ( HR=2.66, 95% CI: 1.53-4.65), and whether to combine radiotherapy ( HR=0.65, 95% CI: 0.42-1.00) were independent influencing factors for the PFS of these patients. The primary tumor site ( HR=0.68, 95% CI: 0.48-0.95), ECOG score ( HR=5.82, 95% CI: 3.14-10.82), and whether to combine radiotherapy ( HR=0.58, 95% CI: 0.35-0.96) were independent influencing factors of the OS of these patients. The most frequent gene mutations in these advanced stage pancreatic patients were KRAS (89.66%), TP53 (77.01%), CDKN2A (32.18%), and SMAD4 (21.84%) by NGS of tumor tissues from 87 pancreatic cancer patients with sufficient specimens. Further analysis revealed that mutations in CDKN2B, PTEN, FGF6, and RBBP8 genes were significantly associated with an increased risk of death ( P＜0.05). Conclusion:Albumin-bound paclitaxel as first-line treatment demonstrated feasible anti-tumor efficacy and manageable safety for patients with advanced pancreatic cancer in China.

To investigate the clinical assessment of dual-enhanced antiplatelet therapy after cerebrovascular intervention to reduce the risk of cerebral infarction recurrence, and to provide a reference for the prevention and treatment of cerebral infarction recurrence risk. 202 patients with cerebral infarction who underwent cerebrovascular intervention in Tianjin Fifth Central Hospital from January 2018 to October 2022 were selected as study subjects. The patients were divided into a treatment group ( n=104) based on randomized controlled single-blind method with 61 males and 43 females with a mean age of (62.33±2.57) years old and a control group ( n=98) with 56 males and 42 females with a mean age of (62.49±2.36) years old. The control group was given aspirin mono-antiplatelet therapy, and the treatment group was given clopidogrel doublet augmented antiplatelet therapy on the basis of the control group, and both groups continued the treatment for 2 months. Platelet counts, coagulation indexes and inflammatory factors were compared between the two groups before and after treatment, and the America National Institutes of Health Stroke Scale (NIHSS) score was used to assess the neurological functions of the two groups before and after treatment, and the recurrence of cerebral infarction in the two groups was counted within 6 months after treatment. In addition, the patients in the treatment group were divided into the cerebral infarction recurrence group and the cerebral infarction non-recurrence group according to whether they had cerebral infarction recurrence within 6 months after treatment, and the clinical data of the patients in the treatment group were collected to analyze the influencing factors of the dual-enhancement antiplatelet therapy for the recurrence of cerebral infarction in patients with cerebral infarction after cerebral vascular intervention by multifactorial logistic regression. The results showed that after treatment, patients in the treatment group had an international normalized ratio (INR) of (1.76±0.38), a platelet activation rate of (39.52±4.79)%, a platelet aggregation rate of (48.54±5.21)%, a tumor necrosis factor-alpha (TNF-alpha) of (28.37±4.47)ng/L, an interleukin 6 (IL-6) of (24.77±3.52)ng/L, a high-sensitivity C-reactive protein (hs-CRP) of (7.39±1.53)mg/L and an NIHSS score of (6.11±1.39) were lower than those of the control group (2.32±0.41), (44.81±6.37)%, (51.39±5.58)%, (39.66±4.51) ng/L, (29.25±4.04) ng/L, (9.03±1.78) mg/L and (9.93±1.46) points (all P<0.05). At 6-month follow-up of all patients, cerebral infarction recurred in 16 (15.38%) patients in the treatment group and in 33 (33.67%) patients in the control group ( χ2=9.185, P<0.05). Kaplan-Meier results showed a statistically significant difference in the rate of recurrence without cerebral infarction in the treatment group compared with the control group(LogRank χ2=4.595, P<0.05). Logistic regression analysis showed that smoking history, cervical vascular plaque, post-treatment NIHSS score, post-treatment stenosis score, post-treatment INR, post-treatment hs-CRP and CYP2C19 gene polymorphism were independent influences on the recurrence of cerebral infarction in cerebral infarction patients with cerebral vascular interventions followed by doublet augmentation of antiplatelet therapy (all P<0.05). In conclusion, dual-enhanced antiplatelet therapy may be an effective measure to reduce the risk of cerebral infarction recurrence after cerebrovascular intervention in patients with cerebral infarction, but it is still influenced by more factors.
