Flexible conductive fibers have been widely applied in wearable flexible sensing. However, exposed wearable flexible sensors based on liquid metal (LM) are prone to abrasion and significant conductivity degradation. This study presented a high-sensitivity LM conductive fiber with integration of strain sensing, electrical heating, and thermochromic capabilities, which was fabricated by coating eutectic gallium-indium (EGaIn) onto spandex fibers modified with waterborne polyurethane (WPU), followed by thermal curing to form a protective polyurethane sheath. This fiber, designated as Spandex/WPU/EGaIn/Polyurethane (SWEP), exhibits a four-layer coaxial structure: spandex core, WPU modification layer, LM conductive layer, and polyurethane protective sheath. The SWEP fiber had a diameter of (458.3 ± 10.4) μm, linear density of (2.37 ± 0.15) g/m, and uniform EGaIn coating. The fiber had excellent conductivity with an average value of (3 716.9 ± 594.2) S/m. The strain sensing performance was particularly noteworthy. A 5 cm × 5 cm woven fabric was fabricated using polyester warp yarns and SWEP weft yarns. The fabric exhibited satisfactory moisture permeability [(536.06 ± 33.15) g/(m ²·h)] and maintained stable thermochromic performance after repeated heating cycles. This advanced conductive fiber development is expected to significantly promote LM applications in wearable electronics and smart textile systems.

Objective To systematically evaluate the efficacy of adjuvant radiotherapy after thymoma resection. Methods The PubMed, EMbase, The Cochrane Library, Web of Science, Wanfang, VIP, CNKI databases were systematically searched to find relevant literature comparing the efficacy and effectiveness of thymoma resection and thymoma resection+postoperative radiation therapy (PORT) for treating thymoma published from inception to January 2024. The Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of included retrospective studies, and Review Manager 5.4 software was used to perform meta-analysis. Results A total of 23 articles were included, all of which were retrospective studies. There were a total of 13742 patients, including 6980 patients in the simple surgery group, with 3321 males and 3659 females, and an average age of 54.08 years; 6762 patients in the surgery+PORT group, with 3385 males and 3377 females, and an average age of 53.76 years. The NOS scores of the included literature were all≥7 points. The results of the meta-analysis showed that compared with the simple surgery group, the surgery+PORT group had higher 1-year overall survival rate [OR=0.32, 95%CI (0.25, 0.42), P<0.001], 3-year overall survival rate [OR=0.55, 95%CI (0.48, 0.64), P<0.001], 5-year overall survival rate [OR=0.66, 95%CI (0.58, 0.75), P<0.001], 10-year overall survival rate [OR=0.71, 95%CI (0.57, 0.88), P=0.002], 1-year disease-free survival rate [OR=0.47, 95%CI (0.23, 0.93), P=0.030], 5-year disease-free survival rate [OR=0.61, 95%CI (0.45, 0.84), P=0.003], 3-year disease-specific survival rate [OR=0.44, 95%CI (0.35, 0.55), P<0.001], 5-year disease-specific survival rate [OR=0.53, 95%CI (0.44, 0.63), P<0.001] and 10-year disease-specific survival rate [OR=0.53, 95%CI (0.35, 0.82), P=0.004]. But there was no statistically significant difference between the two groups in terms of 3-year disease-free survival rate [OR=0.86, 95%CI (0.61, 1.22), P=0.400], 10-year disease-free survival rate [OR=0.70, 95%CI (0.47, 1.05), P=0.080] and 1-year disease-specific survival rate [OR=0.83, 95%CI (0.55, 1.26), P=0.380]. Conclusion PORT after thymoma resection has more advantages than simple surgical treatment in terms of 1-, 3-, 5-, and 10-year overall survival, 1- and 5-year disease-free survival, and 3-, 5- and 10-year disease-specific survival.

Objective To investigate the infectivity of hepatitis A virus(HAV)cell-adapted strain in a type Ⅰ interferon receptor-deficient mouse model.Methods The biological charateristics of HM175/18f were identified,including the viral protein expression and viral proliferation by indirect immunofluorescence,Western blot and real-time quantitative RT-PCR in vitro.Then,type Ⅰ interferon receptor-deficient A129 mice were infected with HM175/18f via intravenous injection.The viral RNA load in serum,feces and liver tissues of infected mice were detected to determine the replication of HAV in vivo.The level of serum alanine aminotransferase(ALT)and HE staining of liver tissues were used to evaluate liver injury.Additionally,the dynamic changes of HAV-specific IgG antibody was detected to assess the humoral immune response induced by HM175/18f.Results A129 mice infected with HM175/18f did not show obvious clinical symptoms,nor was the ALT level significantly elevated.However,viral RNA persisted in the liver tissue of infected mice until 42 days after infection.There was focal infiltration of lymphocytes and neutrophils in the liver tissue of infected mice,but no focal necrosis was observed.More importantly,HM175/18f infection caused significant viremia and sustained fecal virus shedding.In addition,HM175/18f induced a significant HAV-specific humoral immune response in A129 mice.Conclusion Our study has revealed the infectivity of HAV cell-adapted strain HM175/18f in type Ⅰ interferon receptor-deficient mice,and identified the attenuated characteristics of HM175/18f,which not only contributes to our understanding of the pathogenesis of HAV,but also expand the applications of a type Ⅰ interferon receptor-deficient mouse model in the study of hepatitis A.

The effects of host factors ADP-ribosylation factor 4 (ARF4) and ADP-ribosylation factor 5 (ARF5) upon Zika virus (ZIKV) infection in vivo were characterized by construction of gene knockout mice via CRISPR-Cas9. Firstly, ARF5 and ARF4 genes were modified by the CRISPR-Cas9 system and then microinjected into the fertilized eggs of C57BL/6JGpt mice. Fertilized eggs were transplanted to obtain ARF4 or ARF5 knockout (ARF4KO or ARF5KO) mice, and ARF4/5 double knockout mice were achieved by the mating between ARF4KO and ARF5KO mice (ARF4KO/ARF5KO). Then, the mouse genotypes were identified by PCR to identify the positive knockout mice, and RT-qPCR was employed to examine the knockout efficiency. The mice were then infected with ZIKV and the blood and tissue samples were collected after 2, 4, and 6 days. RT-qPCR was then employed to determine the virus load, and hematoxylin-eosin staining was employed to observe the pathological changes in the tissue. The results showed that expected PCR bands were detected from ARF4KO^-/+, ARF5KO^-/-, and ARF4KO^-/+/ARF5KO^-/- mice, respectively. The results of mRNA transcription measurement indicated the significant knockdown of ARF4 by 37.8%-50.0% but not ARF5 in ARF4KO^-/+ compared with the wild-type mice. Meanwhile, complete knockout of ARF5 and no changes in ARF4 were observed in ARF5KO^-/- mice. Additionally, completed knockout of ARF5 and down-regulated mRNA level of ARF4 in the lung, kidney, and testis were detected in ARF4KO^-/+/ARF5KO^-/-mice in comparison with the wild-type mice. The virus load in the serum decreased in ARF4KO^-/+ mice, while it showed no significant change in ARF5KO^-/- or ARF4KO^-/+/ARF5KO^-/- mice compared with that in the wild type. Meanwhile, ARF4KO^-/+ mice showcased no significant difference in virus load in various tissues but attenuated pathological changes in the brain and testis compared with the wild-type mice. We successfully constructed ARF4KO and ARF5KO mice by CRISPR-Cas9 in this study. ARF4 rather than ARF5 is essential for ZIKV infection in vivo. This study provided animal models for studying the roles of ARF4 and ARF5 in ZIKV infection and developing antivirals.

Objective:To establish standard spatial brain template and ROIs template of 11C-methyl- N-2β-carbomethoxy-3β-(4-fluorophenyl)tropane (CFT) PET images for automated quantitative analysis of dopamine transporter (DAT) distribution. Methods:From May 2014 to December 2015, 11C-CFT PET and MRI T 1 brain images of 16 healthy volunteers (3 males, 13 females; age (63.3±6.9) years) from Huashan Hospital, Fudan University were co-registered and smoothed using statistical parametric mapping(SPM)5 software based on MATLAB to create a standard spatial brain template. The ROIs template was established by ScAnVp procedures. These templates were clinically verified by using 11C-CFT PET images of 37 healthy volunteers (23 males, 14 females; age (61.7±7.1) years), 32 Parkinson′s disease (PD) patients (20 males, 12 females; age (61.1±5.4) years), 10 multiple system atrophy with predominant parkinsonism (MSA-P) patients (7 males, 3 females; age (60.8±7.1) years) and 10 progressive supranuclear palsy (PSP) patients (5 males, 5 females; age (58.4±6.1) years) from Huashan Hospital, Fudan University between January 2014 and March 2019. One-way analysis of variance was used to analyze data. Results:Based on the 11C-CFT PET images and MRI T 1 images of healthy volunteers, a standard spatial brain template for normalization of 11C-CFT PET images was created. The ROIs template was established including seven regions: bilateral caudate, anterior putamen, posterior putamen (along the long axis) and the occipital cortex. The ROIs template was accurately aligned in each verification group. The normal reference values of semi-quantitative DAT distribution in caudate, anterior putamen and posterior putamen were obtained (1.84±0.13, 2.18±0.16, 1.77±0.11). The semi-quantitative values of 11C-CFT uptake in each ROI in patients were significantly lower than those in healthy volunteers ( F values: 49.79-283.83, all P<0.05). Conclusion:The established brain templates with accurate spatial alignment for 11C-CFT image analysis can provide foundational tools for the application of 11C-CFT PET imaging in clinical practice and scientific research.

【Objective】 To explore the effect of B lymphocytes on cardiac structure and function and myocardial immune cells during heart development. 【Methods】 Echocardiography, immunofluorescence staining and flow cytometry were used to evaluate the composition of immune cells of the heart and the cardiac structure and function in wild-type (WT) mice and B-lymphocyte-deficient (μMT) mice, respectively. 【Results】 Compared with those of μMT mice, the ratio of heart weight to mouse weight (P<0.05), left ventricular mass (P<0.05) and the cross-sectional area of myocardial cells WT mice were significantly increased, while the ventricular ejection fraction was significantly decreased (P<0.05). The results of mRNA sequencing showed that WT mice and μMT mice differentially expressed genes were mainly enriched in the signal pathway of heart development and hypertrophic cardiomyopathy. The results of flow cytometry showed that WT mice had more Ly6g⁺ neutrophils, CD4⁺ positive T cells (P<0.001) and CD8⁺T cells (P<0.05) compared with μMT mice. 【Conclusion】 B-lymphocyte depletion alters the composition of cardiomyocyte immune cells, reduces left ventricular mass, and increases myocardial contractility.

OBJECTIVE: To investigate the role of pharmacist-led anticoagulation monitoring service for warfarin anticoagulation therapy in patients during hospitalization. METHODS: We retrospectively analyzed the data of 421 patients receiving warfarin anticoagulation therapy during hospitalization between April, 2016 and December, 2017. Of these patients, 316 received daily pharmacist-led anticoagulation monitoring service including checking the patients' International Normalized Ratio (INR) and other pertinent laboratory test results and reviewing medication changes and the patients' clinical status (monitoring group); the other 105 patients receiving warfarin anticoagulation therapy without pharmaceutical care served as the control group. The data including compliance rate of anticoagulant indicators, incidence and rate of prompt management of INR alert, thrombosis and bleeding events during hospitalization were analyzed among these patients. RESULTS: Compared with the control patients, the patients in the monitoring group showed a significantly higher percentage time within target INR range [(73.20±9.46)% (46.32±17.11)%, < 0.001] and a higher qualified rate of INR before discharge (98.42% 60.95%, < 0.001) as well as a higher proper INR-monitoring frequency (97.15% 66.67%, < 0.001). The patients in the monitoring group showed a significantly lower incidence of INR alert than the control patients (8.23% 20.00%, < 0.001) with also a much higher rate of prompt management (96.15% 33.33%). The two groups had similar incidences of clinical events except that the control group reported a higher incidence of minor bleeding episodes (9.52% 2.53%, =0.005). CONCLUSIONS Pharmacist-led anticoagulation monitoring service can significantly improve the effectiveness and safety of warfarin anticoagulation therapy for patients during hospitalization.

BACKGROUND: Vitiligo is a common acquired pigmentary disease caused by destruction of epidermal melanocytes in underlying autoimmune response. Few studies have been focused on the role of chemokines in non-segmental vitiligo (NSV) concomitant with autoimmune thyroid disease (AITD) and alopecia areata (AA). OBJECTIVE: The aim of this study was to determine the best serum biomarker for predictive role in the progression of vitiligo and to evaluate the influence of AA and/or AITD on vitiligo by using the biomarker. METHODS: This prospective cohort study recruited 45 NSV patients: 14 without either AITD or AA, 12 with AITD, 11 with AA, and 8 with both AITD and AA. Serum levels of CXCL1, CXCL8, CXCL9, CXCL10, CXCL12, CXCL13, and CXCL16 were analyzed by ELISA. CXCR3 mRNA expression was detected on PBMCs by RT-PCR. Improvement was evaluated using repigmentation scales. RESULTS: Serum CXCL10 levels, along with the expression of CXCR3 mRNA were higher in NSV patients with AITD or AA alone than in those without AITD or AA. Moreover, serum CXCL10 levels, along with the expression of CXCR3 mRNA were higher in NSV patients with both AITD and AA than in those with AITD or AA alone. Poorer repigmentation was observed in NSV patients with both AA and AITD than in those with AA or AITD alone. CONCLUSION: CXCL10 could be a biomarker to predict the progression of NSV. Dermatologists should pay much attention to those NSV patients concomitant with AITD and/or AA, for comorbidity might lead to more active autoimmune reaction.
