Report on Cardiac Gross Pathologic Measurements of Sudden Cardiac Death in Adults / 法医学杂志

OBJECTIVES@#To analyze the gross pathological data of sudden cardiac death (SCD) with different causes, to provide data support for the identification of sudden cardiac death with unknown causes.@*METHODS@#A total of 167 adult SCD cases in the archive of the Forensic Expertise Institute of Nanjing Medical University from 2010 to 2020 were collected. The gross pathological data of SCD cases were summarized and the characteristics of different causes of death were statistically analyzed.@*RESULTS@#The ratio of male to female SCD cases was 3.4∶1. Coronary heart disease was the leading cause of SCD, and mainly distributed in people over 40 years old. SCD caused by myocarditis was mainly distributed in young people and the mean age of death was (34.00±9.55) years. By analyzing the differences in cardiac pathological parameters of SCD with different causes, it was found that the aortic valve circumference was significantly dilated in the SCD caused by aortic aneurysm or dissection (P<0.05). The heart weight of SCD caused by aortic aneurysm or dissection and combined factors was greater, and both pulmonary and tricuspid valvular rings were dilated in the SCD caused by combined factors in adult males (P<0.05).@*CONCLUSIONS@#Various gross pathological measures of SCD with different causes are different, which has reference value in the cause of death identification of SCD.

Effect of Sodium Salicylate on Calcium Currents and Exocytosis in Cochlear Inner Hair Cells: Implications for Tinnitus Generation / 神经科学通报·英文版

Sodium salicylate is an anti-inflammatory medication with a side-effect of tinnitus. Here, we used mouse cochlear cultures to explore the effects of salicylate treatment on cochlear inner hair cells (IHCs). We found that IHCs showed significant damage after exposure to a high concentration of salicylate. Whole-cell patch clamp recordings showed that 1-5 mmol/L salicylate did not affect the exocytosis of IHCs, indicating that IHCs are not involved in tinnitus generation by enhancing their neuronal input. Instead, salicylate induced a larger peak amplitude, a more negative half-activation voltage, and a steeper slope factor of Ca2+ current. Using noise analysis of Ca2+ tail currents and qRT-PCR, we further found that salicylate increased the number of Ca2+ channels along with CaV1.3 expression. All these changes could act synergistically to enhance the Ca2+ influx into IHCs. Inhibition of intracellular Ca2+ overload significantly attenuated IHC death after 10 mmol/L salicylate treatment. These results implicate a cellular mechanism for tinnitus generation in the peripheral auditory system.

The Effect of Ankle Brace on Biomechanics of the Lower Extremity During Landing: A Systematic Review and Meta Analysis / 医用生物力学

Objective To examine the effects of ankle brace on biomechanics of the lower extremity during landing, so as to provide a theoretic support to choose ankle brace for people with different sports levels. Methods The key words (ankle brace OR ankle braces OR ankle bracing OR ankle support) AND (landing OR land OR jump OR hopped OR hopping) AND (biomechanics OR kinematics OR kinetics OR electromyography OR neuromuscular) in Chinese and English were searched from different electronic databases (CNKI, Web of Science, EBSCO, PubMed and other databases), for a period of Jan. 2000 to Dec. 2020. Cochrane was used to evaluate the quality of eligible studies. For meta analysis, subgroup analysis was used to assess the impact of ankle braces on ankle biomechanics.Results Thirteen studies with a total of 222 participants were included for mata analysis in this study. The semi-rigid ankle brace reduced the peak of ankle inversion by 25.8% compared with the elastic ankle brace (SMD=-0.562, P<0.001). Moreover, the elastic ankle brace reduced ankle plant flexion during landing among athletes (SMD=-3.42, P=-0.021). As for collagiate students, both elastic ankle and semi-rigid ankle decreased the ankle inversion (elastic ankle brace: 35.4%, SMD=-1.000, P=-0.013; semi-rigid ankle brace: 31.11%, SMD=-0.881, P<0.001) and ankle plant flexion (elastic ankle brace:23.30%, SMD=-1.381, P<0.001;semi-rigid ankle brace: 36.33%, SMD=-1.605, P<0.001).Conclusions Both ankle braces can prevent ankle sprain for athletes (basketball, volleyball, running) who experience training more than 5 years. The elastic ankle brace can limit the inversion and plantar flexion, while the semi-rigid ankle brace can merely decrease the ankle inversion. Therefore, athletes are more suitable for the elastic ankle brace. As for collegiate students without training history, both ankle brace can decrease the ankle inversion and plantar flexion. The elastic ankle brace has greater restriction on inversion, while the semi-rigid ankle brace has more restriction on plantar flexion. Therefore, the elastic ankle brace should be utilized if collegiate students have calcaneofibular ligament injury, while the semi-rigid ankle brace is more suitable for collegiate students who have a history of anterior talofibular ligament injury.

Application of the small private online course-based blended teaching model in Human Parasitology teaching / 中国血吸虫病防治杂志

Small private online course (SPOC), an emerging network-based, student-centered blended teaching model, combines the advantages of online teaching and flipped classroom, aiming to effectively improve students’ autonomous learning ability and learning efficiency. Considering a remarkable decline in the course of Human Parasitology, we built an SPOC-based blended teaching model for Human Parasitology, covering pre-course learning, intra-course leaning, post-course consolidation and evaluation, and such a model was applied among grade 2019 students with specialty of clinical medicine. Following the application of the SPOC-based blended teaching model, most students had improvements in autonomous learning ability and activity, and understanding of human parasitology knowledge, and the examination score disparity was avoided.

Objective:To study the safety and efficacy of endoscopic submucosal dissection (ESD) for early gastric cardia cancer (EGCC) in elderly patients.Methods:A retrospective analysis was performed on data of 499 EGCC patients who underwent ESD from January 2011 to June 2018 in Nanjing Drum Tower Hospital. The patients were divided into two groups by age, the young/middle-aged group (<65 years old) and the elderly group (≥65 years old). The baseline data, lesion features, postoperative complications, short-term efficacy and long-term efficacy of the two groups were compared.Results:The elderly group included 272 patients (283 lesions) and the young/middle-aged group included 227 patients (229 lesions). Except that there were significant differences in the age ( P<0.001) and body mass index ( P=0.002) between the elderly group and the young/middle-aged group, there were no significant differences in the baseline data or pathological features between the two groups. The rate of curative resection in the elderly group was 77.0%, lower than that in the young/middle-aged group (84.3%, P=0.045). No significant differences were found in en bloc resection rate (100.0% VS 99.6%, P=1.000), complete resection rate (94.7% VS 93.9%, P=0.705), postoperative complications incidence (6.4% VS 5.7%, P=0.747), operation time (64.02±39.24 min VS 66.16±44.62 min, P=0.566) or hospitalization time (6.76±2.06 d VS 6.47±1.74 d, P=0.092]. After the median follow-up of 47.9 months, 13.4% patients in the elderly group received additional surgery, which was slightly lower than that in the young/middle-aged group ( P=0.891). There were no significant differences in postoperative recurrence, lymph node metastasis, distant metastasis, overall mortality and disease-related mortality between the two groups. The survival analysis showed that five-year overall survival rates were 94.41% and 96.34% in the elderly group and the young/middle-aged group respectively ( P=0.156), and five-year disease-specific survival rate were 99.18% and 99.03% in the two groups respectively ( P=0.858). Conclusion:ESD is safe and effective for EGCC in elderly patients with satisfactory short-term and long-term efficacy.

A smart O2-generating nanocarrier optimizes drug transportation comprehensively for chemotherapy improving

@#Drug transportation is impeded by various barriers in the hypoxic solid tumor, resulting in compromised anticancer efficacy. Herein, a solid lipid monostearin (MS)-coated CaO2/MnO2 nanocarrier was designed to optimize doxorubicin (DOX) transportation comprehensively for chemotherapy enhancement. The MS shell of nanoparticles could be destroyed selectively by highly-expressed lipase within cancer cells, exposing water-sensitive cores to release DOX and produce O2. After the cancer cell death, the core-exposed nanoparticles could be further liberated and continue to react with water in the tumor extracellular matrix (ECM) and thoroughly release O2 and DOX, which exhibited cytotoxicity to neighboring cells. Small DOX molecules could readily diffuse through ECM, in which the collagen deposition was decreased by O2-mediated hypoxia-inducible factor-1 inhibition, leading to synergistically improved drug penetration. Concurrently, DOX-efflux-associated P-glycoprotein was also inhibited by O2, prolonging drug retention in cancer cells. Overall, the DOX transporting processes from nanoparticles to deep tumor cells including drug release, penetration, and retention were optimized comprehensively, which significantly boosted antitumor benefits.

Drug hypersensitivity reactions in Asia: regional issues and challenges

There are geographical, regional, and ethnic differences in the phenotypes and endotypes of patients with drug hypersensitivity reactions (DHRs) in different parts of the world. In Asia, aspects of drug hypersensitivity of regional importance include IgE-mediated allergies and T-cell-mediated reactions, including severe cutaneous adverse reactions (SCARs), to beta-lactam antibiotics, antituberculous drugs, nonsteroidal anti-inflammatory drugs (NSAIDs) and radiocontrast agents. Delabeling of low-risk penicillin allergy using direct oral provocation tests without skin tests have been found to be useful where the drug plausibility of the index reaction is low. Genetic risk associations of relevance to Asia include human leucocyte antigen (HLA)-B*1502 with carbamazepine SCAR, and HLA-B*5801 with allopurinol SCAR in some Asian ethnic groups. There remains a lack of safe and accurate diagnostic tests for antituberculous drug allergy, other than relatively high-risk desensitization regimes to first-line antituberculous therapy. NSAID hypersensitivity is common among both adults and children in Asia, with regional differences in phenotype especially among adults. Low dose aspirin desensitization is an important therapeutic modality in individuals with cross-reactive NSAID hypersensitivity and coronary artery disease following percutaneous coronary intervention. Skin testing allows patients with radiocontrast media hypersensitivity to confirm the suspected agent and test for alternatives, especially when contrasted scans are needed for future monitoring of disease relapse or progression, especially cancers.

Asia Pacific Association of Allergy Asthma and Clinical Immunology White Paper 2020 on climate change, air pollution, and biodiversity in Asia-Pacific and impact on allergic diseases

Air pollution, climate change, and reduced biodiversity are major threats to human health with detrimental effects on a variety of chronic noncommunicable diseases in particular respiratory and cardiovascular diseases. The extent of air pollution both outdoor and indoor air pollution and climate change including global warming is increasing-to alarming proportions particularly in the developing world especially rapidly industrializing countries worldwide. In recent years, Asia has experienced rapid economic growth and a deteriorating environment and increase in allergic diseases to epidemic proportions. Air pollutant levels in many Asian countries especially in China and India are substantially higher than are those in developed countries. Moreover, industrial, traffic-related, and household biomass combustion, indoor pollutants from chemicals and tobacco are major sources of air pollutants, with increasing burden on respiratory allergies. Here we highlight the major components of outdoor and indoor air pollutants and their impacts on respiratory allergies associated with asthma and allergic rhinitis in the Asia-Pacific region. With Asia-Pacific comprising more than half of the world's population there is an urgent need to increase public awareness, highlight targets for interventions, public advocacy and a call to action to policy makers to implement policy changes towards reducing air pollution with interventions at a population-based level.

Association between Chinese Medicine Therapy and Survival Outcomes in Postoperative Patients with NSCLC: A Multicenter, Prospective, Cohort Study / 中国结合医学杂志

OBJECTIVE@#To evaluate the association between Chinese medicine (CM) therapy and disease-free survival (DFS) outcomes in postoperative patients with non-small cell lung cancer (NSCLC).@*METHODS@#This multiple-center prospective cohort study was conducted in 13 medical centers in China. Patients with stage I, II, or IIIA NSCLC who had undergone radical resection and received conventional postoperative treatment according to the National Comprehensive Cancer Network (NCCN) guidelines were recruited. The recruited patients were divided into a CM treatment group and a control group according to their wishes. Patients in the CM treatment group received continuous CM therapy for more than 6 months or until disease progression. Patients in the control group received CM therapy for less than 1 month. Follow-up was conducted over 3 years. The primary outcome was DFS, with recurrence/metastasis rates as a secondary outcome.@*RESULTS@#Between May 2013 and August 2016, 503 patients were enrolled into the cohort; 266 were classified in the CM treatment group and 237 in the control group. Adjusting for covariates, high exposure to CM was associated with better DFS [hazard ratio (HR) = 0.417, 95% confidential interval (CI): 0.307-0.567)]. A longer duration of CM therapy (6-12 months, 12-18 months, >24 months) was associated with lower recurrence and metastasis rates (HR = 0.225, 0.119 and 0.083, respectively). In a subgroup exploratory analysis, CM therapy was also a protective factor of cancer recurrence and metastasis in both stage I-IIIA (HR=0.50, 95% CI: 0.37-0.67) and stage IIIA NSCLC postoperative patients (HR = 0.48, 95% CI: 0.33-0.71), DFS was even longer among CM treatment group patients.@*CONCLUSIONS@#Longer duration of CM therapy could be considered a protective factor of cancer recurrence and metastasis. CM treatment is associated with improving survival outcomes of postoperative NSCLC patients in China. (Registration No. ChiCTR-OOC-14005398).

Fumigaclavine C attenuates adipogenesis in 3T3-L1 adipocytes and ameliorates lipid accumulation in high-fat diet-induced obese mice

Fumigaclavine C (FC), an active indole alkaloid, is obtained from endophytic Aspergillus terreus (strain No. FC118) by the root of Rhizophora stylosa (Rhizophoraceae). This study is designed to evaluate whether FC has anti-adipogenic effects in 3T3-L1 adipocytes and whether it ameliorates lipid accumulation in high-fat diet (HFD)-induced obese mice. FC notably increased the levels of glycerol in the culture supernatants and markedly reduced lipid accumulation in 3T3-L1 adipocytes. FC differentially inhibited the expressions of adipogenesis-related genes, including the peroxisome proliferator-activated receptor proteins, CCAAT/enhancer-binding proteins, and sterol regulatory element-binding proteins. FC markedly reduced the expressions of lipid synthesis-related genes, such as the fatty acid binding protein, lipoprotein lipase, and fatty acid synthase. Furthermore, FC significantly increased the expressions of lipolysis-related genes, such as the hormone-sensitive lipase, Aquaporin-7, and adipose triglyceride lipase. In HFD-induced obese mice, intraperitoneal injections of FC decreased both the body weight and visceral adipose tissue weight. FC administration significantly reduced lipid accumulation. Moreover, FC could dose-dependently and differentially regulate the expressions of lipid metabolism-related transcription factors. All these data indicated that FC exhibited anti-obesity effects through modulating adipogenesis and lipolysis.

Intranasal Immunization Using CTA1-DD as a Mucosal Adjuvant for an Inactivated Influenza Vaccine / 生物医学与环境科学（英文）

OBJECTIVE@#To evaluate the effect of intranasal immunization with CTA1-DD as mucosal adjuvant combined with H3N2 split vaccine.@*METHODS@#Mice were immunized intranasally with PBS (negative control), or H3N2 split vaccine (3 μg/mouse) alone, or CTA1-DD (5 μg/mouse) alone, or H3N2 split vaccine (3 μg/mouse) plus CTA1-DD (5 μg/mouse). Positive control mice were immunized intramuscularly with H3N2 split vaccine (3 μg/mouse) and alum adjuvant. All the mice were immunized twice, two weeks apart. Then sera and mucosal lavages were collected. The specific HI titers, IgM, IgG, IgA, and IgG subtypes were examined by ELISA. IFN-γ and IL-4 were test by ELISpot. In addition, two weeks after the last immunization, surivival after H3N2 virus lethal challenge was measured.@*RESULTS@#H3N2 split vaccine formulated with CTA1-DD could elicit higher IgM, IgG and hemagglutination inhibition titers in sera. Furthermore, using CTA1-DD as adjuvant significantly improved mucosal secretory IgA titers in bronchoalveolar lavages and vaginal lavages. Meanwhile this mucosal adjuvant could enhance Th-1-type responses and induce protective hemagglutination inhibition titers. Notably, the addition of CTA1-DD to split vaccine provided 100% protection against lethal infection by the H3N2 virus.@*CONCLUSION@#CTA1-DD could promote mucosal, humoral and cell-mediated immune responses, which supports the further development of CTA1-DD as a mucosal adjuvant for mucosal vaccines.

Measuring the quality of life of the families of children with eczema in Hong Kong

BACKGROUND: Eczema is the most common skin problem among children in Hong Kong. Previous studies have highlighted that the quality of life of the families of children with eczema influences the effects of eczema interventions. However, the Chinese version of the Family Dermatology Life Quality Index (C-FDLQI), a tool for measuring the quality of life of the families of children with eczema, has not yet been validated. OBJECTIVE: This study examined the psychometric properties of the C-FDLQI among parents and caregivers of children with eczema in Hong Kong. METHODS: This study evaluated the internal consistency, test-retest reliability and structural validity of the C-FDLQI and its convergent validity by examining its correlations with the SCORing Atopic Dermatitis (SCORAD) and the Cantonese version of the Children’s Dermatology Life Quality Index (C-CDLQI) among 147 Chinese parents/caregivers of children with varying degrees of eczema.
