OBJECTIVE: This study aimed to reveal the insomnia burden and relevant influencing factors among informal caregivers (ICs) of hospitalized patients with lung cancer. METHODS: A cross-sectional study on ICs of hospitalized patients with lung cancer was conducted from December 31, 2020 to December 31, 2021. ICs' burden was assessed using the Caregiver Reaction Assessment (CRA), Hospital Anxiety and Depression Scale (HADS), and Insomnia Severity Index (ISI). Linear and logistic regression models were used to identify the influencing factors. RESULTS: Among 289 ICs of hospitalized patients with lung cancer, 83 (28.72%), 53 (18.34%), and 14 (4.84%) ICs experienced mild, moderate, and severe insomnia, respectively. The scores concerning self-esteem, lack of family support, financial problems, disturbed schedule, and health problems were 4.32 ± 0.53, 2.24 ± 0.79, 2.84 ± 1.14, 3.63 ± 0.77, and 2.44 ± 0.95, respectively. ICs with higher Activities of Daily Living Scale (ADLS) scores were associated with a lower risk of insomnia, with an odd ratio ( OR) and 95% confidence interval ( CI) of 0.940 (0.898-0.983). Among the ICs, female gender ( OR = 2.597), alcohol consumption ( OR = 3.745), underlying medical conditions ( OR = 11.765), long-term caregiving experience ( OR = 37.037), and higher monthly expenses ( OR = 5.714) were associated with a high risk of insomnia. CONCLUSION Of the hospitalized patients with lung cancer, 51.9% experienced insomnia. Patients' ADL, ICs gender, alcohol consumption, underlying medical conditions, caregiving duration, and monthly expenses were influencing factors. Therefore, prompt screening and early intervention for ICs of patients with lung cancer is necessary.

Objective: To explore the risk intensity and related influencing factors of post-traumatic stress disorder (PTSD) among high-stress rescue workers, and to provide effective tools for the risk assessment of PTSD in military rescue workers. Method: From June to August 2022, cluster sampling was used to select the high-stress rescue personnel of an Army department as the survey subjects. The acute Stress reaction (ASD) scale and PTSD checklist were used to evaluate the risk of PTSD in military rescue personnel. Multivariate logistic regression were used to analyze the influencing factors of PTSD. Results: The age of 4 460 subjects was (24.38±4.072) years old, including 4 396 males (98.6%). The positive rate of initial screening for ASD was 2.85% (127/4 460). The positive rate of PTSD was 0.67% (30/4 460). Multivariate logistic regression model analysis showed that female, older age, recent trauma exposure history, passive smoking and alcohol consumption were at higher risk of ASD, the values of OR (95%CI) were 4.183 (1.819-9.618), 6.278 (1.363-28.912), 3.094 (1.500-6.379), 2.059 (1.298-3.267) and 2.607 (1.614-4.211), respectively; Lower education level was associated with lower risk of ASD, OR (95%CI) was 0.593 (0.359-0.978); People who are older, thinner, have a history of mental illness, and drink alcohol were at higher risk for PTSD, the values of OR (95%CI) were 20.144 (2.459-165.043), 10.287 (2.218-47.700), 91.104 (8.592-965.980) and 2.866 (1.144-7.180), respectively. Conclusion: Gender, age, education level, passive smoking, alcohol consumption, past history of mental illness and body mass index may be related to the potential risk of PTSD in rescue workers,passive smoking, alcohol consumption, and weight controlling should be focused on to reduce potential risks of PTSD.

OBJECTIVE: Current clinical evidence on the effects of home blood pressure telemonitoring (HBPT) on improving blood pressure control comes entirely from developed countries. Thus, we performed this randomized controlled trial to evaluate whether HBPT plus support (patient education and clinician remote hypertension management) improves blood pressure control more than usual care (UC) in the Chinese population. METHODS: This single-center, randomized controlled study was conducted in Beijing, China. Patients aged 30-75 years were eligible for enrolment if they had blood pressure [systolic (SBP) ≥ 140 mmHg and/or diastolic (DBP) ≥ 90 mmHg; or SBP ≥ 130 mmHg and/or DBP ≥ 80 mmHg with diabetes]. We recruited 190 patients randomized to either the HBPT or the UC groups for 12 weeks. The primary endpoints were blood pressure reduction and the proportion of patients achieving the target blood pressure. RESULTS: Totally, 172 patients completed the study, the HBPT plus support group ( n = 84), and the UC group ( n = 88). Patients in the plus support group showed a greater reduction in mean ambulatory blood pressure than those in the UC group. The plus support group had a significantly higher proportion of patients who achieved the target blood pressure and maintained a dipper blood pressure pattern at the 12th week of follow-up. Additionally, the patients in the plus support group showed lower blood pressure variability and higher drug adherence than those in the UC group. CONCLUSION HBPT plus additional support results in greater blood pressure reduction, better blood pressure control, a higher proportion of dipper blood pressure patterns, lower blood pressure variability, and higher drug adherence than UC. The development of telemedicine may be the cornerstone of hypertension management in primary care.

The mimetic exosomes simulate the structure of exosomes and achieve safe and efficient co-delivery of multi-component drugs.

ObjectivePercutaneous coronary intervention (PCI) may cause acute kidney injury (AKI) in some patients with acute coronary syndrome (ACS), leading to persistent renal dysfunction. This study aimed to investigate the relationship between acute kidney injury after PCI and short-term prognosis in patients with ACS.MethodsData of 333 patients with ACS who underwent PCI in our hospital were included. According to whether the serum creatinine level was increased above 25% during 1st to 3rd day after PCI than the preoperative, patients was divided into AKI group (n=38) and non-AKI group (n=295). Risk factors for AKI in patients with ACS after PCI were analyzed. Adverse cardiovascular events and survival rates between the two groups were compared. Univariate and multivariate analysis were performed to determine the risk factors on short-term survival after surgery.ResultsAge, diabetes, preoperative renal insufficiency, left ventricular ejection fraction (LVEF), contrast dose and count of lesion coronary artery were independent risk factors for AKI after PCI (P<0.05). Within 1 year after surgery, the total incidence of cardiovascular adverse events in the AKI group and the non-AKI group were 28.9% and 5.8%, respectively, and the difference was statistically significant(χ2=20.582, P=0.000). The patients were followed up for 2.9 to 17.2 months with a median follow up of 8.6 months. The 6-month cumulative survival rate of AKI group and non-AKI group were 94.1% and 99.6%, respectively. The 1 year cumulative survival rate was 84.2% and 96.1%, respectively. The difference in overall survival rate between the two groups was statistically significant(χ2=9.216, P=0.002). Short-term survival after PCI was associated with AKI(χ2=20.582, P=0.000), LVEF (χ2=9.055, P=0.003), count of lesion coronary artery (χ2=5.749, P=0.016) and preoperative Killip grading(χ2=4.823, P=0.028). AKI and LVEF were independent predictors of short-term survival after PCI (P<0.05).ConclusionAKI in patients with ACS after PCI has a poorer short-term prognosis, which can be used as an important factor in disease assessment and risk stratification.

Objective: To determine the factors influencing insomnia and construct early insomnia warning tools for rescuers to informbest practices for early screening and intervention. Methods: Cluster sampling was used to conduct a cross-sectional survey of 1,133 rescuers from one unit in Beijing, China. Logistic regression modeling and R software were used to analyze insomnia-related factors and construct a PRISM model, respectively. Results: The positive rate of insomnia among rescuers was 2.74%. Accounting for participants' age, education, systolic pressure, smoking, per capita family monthly income, psychological resilience, and cognitive emotion regulation, logistic regression analysis revealed that, compared with families with an average monthly income less than 3,000 yuan, the odds ratio ( ) values and the [95% confidence interval ( )] for participants of the following categories were as follows: average monthly family income greater than 5,000 yuan: 2.998 (1.307-6.879), smoking: 4.124 (1.954-8.706), and psychological resilience: 0.960 (0.933-0.988). The ROC curve area of the PRISM model (AUC) = 0.7650, specificity = 0.7169, and sensitivity = 0.7419. Conclusion Insomnia was related to the participants' per capita family monthly income, smoking habits, and psychological resilience on rescue workers. The PRISM model's good diagnostic value advises its use to screen rescuer early sleep quality. Further, advisable interventions to optimize sleep quality and battle effectiveness include psychological resilience training and smoking cessation.

At present, it is generally believed that the paracrine effect of stem cells in the repair of myocardial injury is one of the important ways for stem cell therapy. Exosomes are phospholipid bilayer-enclosed nanovesicles that secreted by cells under physiological and pathological conditions. Cargo loaded into exosomes including protein, lipids and nucleic acids can be delivered to recipient cells. Therefore, exosomes are recognized as important mediators for intercellular communication. It has been suggested that exosomes from stem cells (eg. embryonic stem cells, induced pluripotent stem cells, cardiac progenitor cells, mesenchymal stem cells and cardiosphere-derived cells) have protective effects against heart injury. In this review, we summarized recent research progresses on stem cell-derived exosomes in myocardial injury, including the therapeutic effects and mechanism.

Objective To investigate the dynamic expression of transforming growth factor-β1 (TGF-β1) and heat shock protein 47 (HSP47) and explore their roles in the progression of hepatic fibrosis induced by Schistosoma japonicum infection. Methods Fifty female mice of the ICR strain were randomly divided into the infection group and the normal control group, of 25 mice in each group. Each mouse in the infection group was infected with 20 ± 1 cercariae of S. japonicum via the abdominal skin, while uninfected animals served as normal control. Five mice were sacrificed 4, 6, 8, 10 and 12 weeks post-infection and liver tissues were sampled. Serum HSP47 and TGF-β1 was determined using enzyme-linked immunosorbent assay (ELISA), and the pathological changes of liver specimens were observed with hematoxylin & eosin (HE) staining. In addition, the synthesis of alpha 1 chain of type I collagen (COL1A1) was measured using Masson staining, and the mRNA expression of TGF-β1, HSP47 and COL1A1 was determined using real-time fluorescent quantitative PCR (qPCR) assay. Results During the period of S. japonicum-induced hepatic fibrosis, the serum HSP47 and TGF-β1 levels and the mRNA expression of TGF - β1, HSP47 and COL1A1 gradually increased with the progression of hepatic fibrosis. The serum levels of HSP47 and TGF-β1 were (179.26 ± 29.87) pg/mL and (22.37 ± 5.21) ng/mL 6 weeks post-infection, respectively, which were significantly greater than those [(150.29 ± 34.91) pg/mL and (18.54 ± 7.78) ng/mL, respectively] in the normal control group (both P values < 0.05). In addition, the mRNA expression of HSP47, COL1A1 and TGF-β1 was (0.86 ± 0.04), (1.17 ± 0.06) and (0.64 ± 0.13) in mouse liver specimens, which was significantly higher than that (0.23 ± 0.03, 0.20 ± 0.02 and 0.38 ± 0.02) in the normal control group (all P values < 0.01). Conclusions The expression of TGF-β1 and HSP47 during the period of S. japonicum-induced hepatic fibrosis is consistent with the progression of the hepatic fibrosis, and exhibits the same tendency with type I collagen expression. HSP47 is a novel promising diagnosis marker and therapeutic target for S. japonicum-induced hepatic fibrosis.
