Objective: To evaluate the immunogenicity, safety, and immune persistence of the sequential booster with the recombinant protein-based COVID-19 vaccine (CHO cell) in healthy people aged 18-84 years. Methods: An open-label, multi-center trial was conducted in October 2021. The eligible healthy individuals, aged 18-84 years who had completed primary immunization with the inactivated COVID-19 vaccine 3 to 9 months before, were recruited from Shangyu district of Shaoxing and Kaihua county of Quzhou, Zhejiang province. All participants were divided into three groups based on the differences in prime-boost intervals: Group A (3-4 months), Group B (5-6 months) and Group C (7-9 months), with 320 persons per group. All participants received the recombinant COVID-19 vaccine (CHO cell). Blood samples were collected before the vaccination and after receiving the booster at 14 days, 30 days, and 180 days for analysis of GMTs, antibody positivity rates, and seroconversion rates. All adverse events were collected within one month and serious adverse events were collected within six months. The incidences of adverse reactions were analyzed after the booster. Results: The age of 960 participants was (52.3±11.5) years old, and 47.4% were males (455). The GMTs of Groups B and C were 65.26 (54.51-78.12) and 60.97 (50.61-73.45) at 14 days after the booster, both higher than Group A's 44.79 (36.94-54.30) (P value<0.05). The GMTs of Groups B and C were 23.95 (20.18-28.42) and 27.98 (23.45-33.39) at 30 days after the booster, both higher than Group A's 15.71 (13.24-18.63) (P value <0.05). At 14 days after the booster, the antibody positivity rates in Groups A, B, and C were 91.69% (276/301), 94.38% (302/320), and 93.95% (295/314), respectively. The seroconversion rates in the three groups were 90.37% (272/301), 93.75% (300/320), and 93.31% (293/314), respectively. There was no significant difference among these rates in the three groups (all P values >0.05). At 30 days after the booster, antibody positivity rates in Groups A, B, and C were 79.60% (238/299), 87.74% (279/318), and 90.48% (285/315), respectively. The seroconversion rates in the three groups were 76.92% (230/299), 85.85% (273/318), and 88.25% (278/315), respectively. There was a significant difference among these rates in the three groups (all P values <0.001). During the sequential booster immunization, the incidence of adverse events in 960 participants was 15.31% (147/960), with rates of about 14.38% (46/320), 17.50% (56/320), and 14.06% (45/320) in Groups A, B, and C, respectively. The incidence of adverse reactions was 8.02% (77/960), with rates of about 7.50% (24/320), 6.88% (22/320), and 9.69% (31/320) in Groups A, B, and C, respectively. No serious adverse events related to the booster were reported. Conclusion: Healthy individuals aged 18-84 years, who had completed primary immunization with the inactivated COVID-19 vaccine 3 to 9 months before, have good immunogenicity and safety profiles following the sequential booster with the recombinant COVID-19 vaccine (CHO cell).

Research progress on the correlation between genetic factors and sudden cardiac death in the elderly / 中华老年医学杂志

Sudden cardiac death(SCD)in the elderly is defined as a sudden accidental death in patients over 65 years of age within one hour of symptom onset or within 24 hours with no symptoms, possibly due to arrhythmia or abrupt hemodynamic changes.It is characterized by rapid onset, rapid progression, and high mortality.Sudden cardiac death in the elderly is the most serious clinical syndrome in elderly patients with heart disease.It accounts for more than 80% of all sudden death cases and is the cause of sudden death in the vast majority of elderly patients.Clinical methods for the detection of sudden cardiac death include mostly screening through family and personal history, physical examination, electrocardiogram analysis and echocardiography, but their drawbacks include lack specificity, low detection rates and relatively limited scenarios for their use.Genetic susceptibility is also responsible for sudden cardiac death.Genetic factors play an important role in the occurrence and development of sudden cardiac death.This review summarized the correlation between sudden death and genetic factors underlying different cardiovascular diseases, including the role of genetic polymorphisms in the occurrence of sudden cardiac death in older adults.

Factors Influencing and Adverse Reactions of Voriconazole Clearance in Patients with Hematological Diseases / 中国实验血液学杂志

OBJECTIVE@#To monitor the changes of voriconazole minimum concentration(Cmin) in patients with hematological diseases, and evaluate the factors influencing and adverse reactions of voriconazole clearance in patients with hematological diseases, so as to provide a theoretical basis for reasonable clinical use of voriconazole.@*METHODS@#136 patients with hematological diseases who used voriconazole in Wuhan NO.1 Hospital from May 2018 to December 2019 were selected. The correlation between C-reactive protein, albumin, creatinine and voriconazole Cmin were analyzed, and the changes of voriconazole Cmin after glucocorticoid treatment was also detected. In addition, stratified analysis was used to explore the adverse events of voriconazole.@*RESULTS@#Among 136 patients, 77 were male (56.62%) and 59 were female (43.38%). There were positive correlations between voriconazole Cmin and C-reactive protein and creatinine levels (r=0.277, r=0.208), while voriconazole Cmin was negatively correlated with albumin level (r=-2.673). Voriconazole Cmin in patients treated with glucocorticoid was decreased significantly (P<0.05). In addition, sratified analysis of voriconazole Cmin showed that compared with voriconazole Cmin 1.0-5.0 mg/L group, the incidence of adverse reactions of visual impairment in voriconazole Cmin> 5.0 mg/L group was increased (χ2=4.318, P=0.038).@*CONCLUSION@#The levels of C-reactive protein, albumin and creatinine are closely related to the voriconazole Cmin, which indicate that inflammation and hyponutrition may prevent the clearance of voriconazole in patients with hematological diseases. It is necessary to monitor the voriconazole Cmin of patients with hematological diseases, and adjust the dosage in time to reduce adverse reactions.

Study on the mechanism of heterogeneous nuclear ribonucleoprotein L promoting the proliferation of hepatocellular carcinoma cells / 中华肝胆外科杂志

Objective:To investigate the effect of HNRNPL protein on the proliferative ability of primary hepatocellular carcinoma cells and its potential mechanism.Methods:Online public database and real-time quantitative PCR were used to analyze the difference of HNRNPL expression between cancer and adjacent tissues. The effects of HNRNPL on HCC cell MHCC97H and HepG2 proliferation and MAPK pathway were investigated by Western blot, cell counting assay, colony formation assay and nude mouse transplantation tumor experiments.Results:The level of HNRNPL mRNA was validated to be higher in HCC tissue (2.76±0.37) than in normal tissue (1.00±0.14) with statistical difference ( t=3.93, P=0.002). Colony formation assay showed that the colony numbers of two MHCC97H knockdown groups (33.3±7.7) and (43.3±2.2) were lower than their control group (84.3±6.2), and two HepG2 knockdown groups (59.0±15.5) and (41.7±4.8) were lower than their control group (200.3±6.2) with statistical difference (both P<0.01). HNRNPL knockdown decreased the proliferation ability and activation level of MAPK pathway in HCC cells. Overexpression of oncogene c-RAF partially alleviated the anti-proliferation effect of HNRNPL knockdown and rescued the tumorigenic capacity. Conclusion:HNRNPL can promote hepatocellular carcinoma cell proliferation by activating MAPK signaling pathway.

Study on factors associated with non-variceal upper gastrointestinal bleeding in hospitalized elderly patients / 中华老年医学杂志

Objective:To investigate factors related to non-variceal upper gastrointestinal bleeding(NVUGIB)in hospitalized elderly patients.Methods:A retrospective study was conducted to collect the medical records of 1 085 elderly patients at the Affiliated Hospital of Qingdao University from January 1, 2018 to January 1, 2019.According to whether NVUGIB occurred during hospitalization, they were divided into the bleeding group(173 cases)and the control group(912 cases). General information(age, sex, smoking and drinking), diseases, medications and laboratory test results for the two groups were compared and analyzed, and factors related to NVUGIB were analyzed via binary Logistic regression.Results:There were significant differences in age, smoking, drinking, peptic ulcer, tumor, coronary heart disease, atrial fibrillation, stroke, helicobacter pylori(HP)infection, acute respiratory failure, use of anti-coagulant, anti-platelet drugs, nonsteroidal anti-inflammatory drugs and glucocorticoids, leukocyte counts, hemoglobin, C-reactive protein, procalcitonin, prothrombin time and international normalized ratio(INR), D-dimer, triglycerides, albumin and glycosylated hemoglobin(all P<0.05). Multivariate Logistic regression analysis showed that history of tumor( OR=1.552, 95% CI: 1.028-2.344), peptic ulcer( OR=4.797, 95% CI: 2.263-10.165), HP infection( OR=7.199, 95% CI: 1.825-28.571), acute respiratory failure( OR=2.977, 95% CI: 1.314-6.757), use of anti-coagulant and anti-platelet drugs( OR=2.715, 95% CI: 1.769-4.167), prolonged INR( OR=21.314, 95% CI: 2.321-195.727), increased leukocyte count( OR=10.370, 95% CI: 6.521-16.493)and hypoproteinemia( OR=1.970, 95% CI: 1.304-2.976)were independent risk factors for NVUGIB in hospitalized elderly patients. Conclusions:For hospitalized elderly patients, attention should be paid to their history of tumor, peptic ulcer, HP infection, acute respiratory failure, prolonged INR, elevated leukocyte counts, hypoalbuminemia and the use of anti-coagulant and anti-platelet drugs.The occurrence of NVUGIB, early evaluation and intervention should be carefully monitored or carried out to reduce its incidence in hospitalized elderly patients.

Effect of hyperbaric oxygen therapy on myocardial fibrosis and expression of oxidative stress-related indicators in D-galactose-induced senescent model mice / 中华老年医学杂志

Objective:To investigate the protective effect of hyperbaric oxygen therapy(HBOT)on myocardial fibrosis and oxidative stress induced by D-galactose(D-gal)in senescent model mice and its possible mechanism.Methods:Three-month-old male Kunming mice(n=27)were randomized into control, D-gal, and D-gal + HBOT groups.The control group received subcutaneous sterilized saline(5 ml · kg -1· d -1)for 8 weeks; the remaining 2 groups received subcutaneous D-gal(200 mg · kg -1· d -1)for 8 weeks. The D-gal + HBOT group underwent HBOT intervention at week 7~8.At the end of the experiment, the histopathological changes were analyzed by hematoxylin-eosin(HE)staining, and the fibrosis changes were analyzed by Masson staining and Sirius red staining.Oxidative stress kit was used to detect catalase(CAT), total superoxide dismutase(T-SOD)activity and malon-di-aldehyde(MDA)content in serum of mice.Western blotting was used to detect the expression levels of the aging-related proteins p53 and p16 in mouse heart tissue, the heart-function-related proteins atrial natriuretic peptide(ANP)and brain natriuretic peptide(BNP), and the oxidative stress-related protein superoxide dismutase 1(SOD1), superoxide dismutase 2(SOD2)and catalase(CAT). Results:Cardiac morphologic staining indicated that as compared with the control group, mice of D-gal group exhibited features of senescence and the increased fibrosis area, and senescence and fibrosis were obviously improved after HBOT intervention as compared with the D-gal group.The findings of the oxidative stress kit measurement indicated that as compared with the control group, the D-gal group had markedly decreased activities of CAT and T-SOD, significantly increased MDA content in the serum.After HBOT treatment, as compared with d-gal group, serum CAT and T-SOD activities were increased, while MDA content was decreased( F=126.85, 32.89, 157.50, all P<0.05).Furthermore, as compared with the control group, the D-gal group had obviously increased contents of p53, p16, ANP and BNP, while the content of CAT, SOD1 and SOD2 were obviously decreased.After HBOT intervention, as compared with the D-gal group, the contents of p53, p16, ANP、BNP were reduced, while the content of CAT, SOD1 and SOD2 were increased( F=36.37, 14.81, 23.28, 58.41, 12.79, 80.08, 6.63, all P<0.05). Conclusions:HBOT intervention could protects against cardiac injury in aging mice, which may be related to attenuating myocardial fibrosis, inducing the expression of antioxidant enzymes, and reducing oxidative stress.

Objective To investigate the impact of sarcopenia on muscle strength and exercise capacity in elderly patients with chronic heart failure (CHF).Methods One hundred and sixteen inpatient aged ≥65 years with CHF were enrolled in the study.General clinical characteristics were collected with questionnaire;the appendicular skeletal muscle mass (ASM) was assessed with body composition analyzer;the arm muscle strength was measured and a 6m-walk test was performed.The sarcopenia was evaluated according to the Asian Working Group for Sarcopenia (AWGS) criteria.Simple regression analysis and logistic regression were used to analyze the correlation between sarcopenia and decreased muscle strength,exercise capacity in elderly CHF patients.Results Among 116 elderly CHF patients,sarcopenia was confirmed in 42 patients(36.2％).Patients with sarcopenia had poorer cardiac function and lower muscle strength,ASM and 6m-walking speed than patients without sarcopenia did(allP＜0.05).Simple regression analysis showed positive correlation between ASM and muscle strength in both groups.Logistic regression analysis showed that after adjustment for confounders,ASM reduction was an independent risk factor for reducedexercisecapacity(OR=0.158,95％CI:0.055-0.455,P＜0.05).Conclusion Sarcopenia is a common complication in elderly patients with CHF and may lead to decreased muscle strength and exercise capacity.

E-noise: An increasingly relevant health risk / 中西医结合学报

This article briefly reviews and discusses the current status of major non-communicable diseases (mNCDs), definition of e-noise, its possible link as a risk factor for cardiovascular diseases and other mNCDs, and proposes possible mechanisms and hypotheses on that link, and how to control e-noise in the future. E-noise is defined as signal from electronic products and instruments that emit radiation and electromagnetic fields. It includes not only the acoustic but also non-acoustic noise. Just like road traffic and aircraft noises, e-noise may not only lead to hearing loss and health problems such as fatigue, stress, irritability, headache, and insomnia, but may also endanger cardiovascular health and result in hypertension, ischemic heart disease (myocardial infarction), arrhythmia (atrial fibrillation) and stroke; brain and metabolic problems such as obesity and diabetes; mental and cognitive impairment; as well as changing of humans' long-evolved cortisol and circadian rhythms after long-term exposure. Even short-term exposure to excessive e-noise may lead to heightened stress responses and low quality of life. In conclusion, e-noise is a potential danger in our world, and further studies are needed of its effects on mechanisms of aging, disease, and human health.

Cohort study on determinants of mental health of migrant adolescents in junior high schools / 中华疾病控制杂志

Objective To analyze the status, changing trends and determinants of mental health of migrant adolescents in junior high schools. Methods All of the data came from China Education Panel Survey (CEPS). CEPS baseline survey was conducted during the 2013-2014 school year by using a stratified multistage probability sampling design. 10 279 nationally representative adolescents from the seventh grade in junior high schools were enrolled in the base school year of data collection and 9 449 participants were followed up at the second wave of data collection during the 2014-2015 school year. Our analytic sample (n=1 645) included all the migrant adolescents who had valid data on mental health. Based on CEPS self-reported mental health scale, t-test method and multivariate linear regression model were used to examine the determinants of mental health of migrant adolescents by performing univariate analysis and multivariate analysis. Results The baseline mental health score of migrant adolescents was (8.33±3.31), higher than that of non-migrant adolescents, and significantly increased to (8.60±3.79) in the follow-up school year. 43.3% of participants had negative mental status at higher frequency as time went on. Sex, cognitive skills, co-residence arrangements, numbers of siblings and school rankings were significant influencing factors for mental health score of migrant adolescents. Conclusions The mental health status of migrant adolescents are more vulnerable than that of non-migrant adolescents and continue deteriorating. Among migrant adolescents, female, those with weak cognitive skills, those who do not live with both parents, those who are not only children and those in schools ranking medium and above are more likely to have a poor mental health state.
