In the past 30 years, the accessibility and quality index of medical care have made remarkable progress in China, ranking the first among middle-income countries. Many cardiovascular technologies are at or near the world's leading level, and significant progress has been achieved in China solving the problem of “treatment difficulty” of cardiovascular diseases (CVD). However, due to the prevalence of unhealthy lifestyles among Chinese residents, a huge population with CVD risk factors, accelerated population aging, and other reasons, the incidence and mortality rate of CVD are still increasing, and the turning point of the decline in disease burden has not appeared yet in China. In terms of proportions of disease mortality among urban and rural residents, CVD still ranks the first. In 2020, CVD accounted for 48.00% and 45.86% of the causes of death in rural and urban areas, respectively; two out of every five deaths were due to CVD. It is estimated that the number of current CVD patients in China is around 330 million, including 13 million stroke, 11.39 million coronary heart disease, 8.9 million heart failure, 5 million pulmonary heart disease, 4.87 million atrial fibrillation, 2.5 million rheumatic heart disease, 2 million congenital heart disease, 45.3 million peripheral artery disease, and 245 million hypertension cases. China has entered a new stage of transformation from high-speed development to high-quality development, and the prevention and control of CVD in China should also shift from previous emphasis on scale growth to strategies focusing more on strategic and key technological development in order to curb the trend of increasing incidence and mortality rates of CVD.

In 2019, cardiovascular disease (CVD) accounted for 46.74% and 44.26% of all deaths in rural and urban areas, respectively. Two out of every five deaths were due to CVD. It is estimated that about 330 million patients suffer from CVD in China. The number of patients suffering from stroke, coronary heart disease, heart failure, pulmonary heart disease, atrial fibrillation, rheumatic heart disease, congenital heart disease, lower extremity artery disease and hypertension are 13.00 million, 11.39 million, 8.90 million, 5.00 million, 4.87 million, 2.50 million, 2.00 million, 45.30 million, and 245.00 million, respectively. Given that China is challenged by the dual pressures of population aging and steady rise in the prevalence of metabolic risk factors, the burden caused by CVD will continue to increase, which has set new requirements for CVD prevention and treatment and the allocation of medical resources in China. It is important to reduce the prevalence through primary prevention, increase the allocation of medical resources for CVD emergency and critical care, and provide rehabilitation services and secondary prevention to reduce the risk of recurrence, re-hospitalization and disability in CVD survivors. The number of people suffering from hypertension, dyslipidemia and diabetes in China has reached hundreds of millions. Since blood pressure, blood lipids, and blood glucose levels rise mostly insidiously, vascular disease or even serious events such as myocardial infarction and stroke often already occured at the time of detection in this population. Hence, more strategies and tasks should be taken to prevent risk factors such as hypertension, dyslipidemia, diabetes, obesity, and smoking, and more efforts should be made in the assessment of cardiovascular health status and the prevention, treatment, and research of early pathological changes.

Objective This study was designed to provide the evidences on the toxicokinetics of microplastics (MPs) and nanoplastics (NPs) in the bodies of mammals. Methods 100 nm, 3 μm, and 10 μm fluorescent polystyrene (PS) beads were administered to mice once by gavage at a dose of 200 mg/kg body weight. The levels and change of fluorescence intensity in samples of blood, subcutaneous fat, perirenal fat, peritesticular fat, cerebrum, cerebellum, testis, and epididymis were measured at 0.5, 1, 2, and 4 h after administration using an IVIS Spectrum small-animal imaging system. Histological examination, confocal laser scanning, and transmission electron microscope were performed to corroborate the findings. Results After confirming fluorescent dye leaching and impact of pH value, increased levels of fluorescence intensity in blood, all adipose tissues examined, cerebrum, cerebellum, and testis were measured in the 100 nm group, but not in the 3 and 10 μm groups except in the cerebellum and testis at 4 h for the 3 μm PS beads. The presence of PS beads was further corroborated. Conclusion After a single oral exposure, NPs are absorbed rapidly in the blood, accumulate in adipose tissues, and penetrate the blood-brain/testis barriers. As expected, the toxicokinetics of MPs is significantly size-dependent in mammals.

Objective To investigate the trends of lipid profiles and dyslipidemia among Chinese adults from 2002 to 2015. Methods Data were collected from three nationally representative cross-sectional surveys. Fasting venous blood samples were collected and serum lipids were tested by biochemical analysis and enzymatic determination. Lipid levels and the prevalence of dyslipidemia among adults were analyzed with complex sampling weighting adjustment for age and gender. Results The weighted means of TC, TG, and LDL-c significantly increased linearly from 3.93, 1.12, and 2.12 mmol/L in 2002 to 4.59, 1.41, and 2.78 mmol/L in 2010 and then to 4.63, 1.47, and 2.87 mmol/L in 2015, respectively; by contrast, HDL-c levels decreased significantly from 1.30 mmol/L to 1.26 mmol/L over the same period. Similar trends in mean non-HDL-c and lipid-related ratios were observed. The weighted dyslipidemia prevalence linearly increased; in particular, hypercholesterolemia increased from 1.6% to 5.6% and then to 5.8%, hypertriglyceridemia increased from 5.7% to 13.6% and then to 15.0%, low HDL-c increased from 18.8% to 35.5% and then to 24.9%, and high LDL-c increased from 1.3% to 5.6% and then to 7.2% (P for trend < 0.001). Conclusion Dyslipidemia increased among Chinese adults from 2002 to 2015. Development of a comprehensive strategy to decrease lipid levels in this population is urgently required.

Objective To estimate the burden of cirrhosis and other chronic liver diseases caused by specific etiologies in China. Methods Data from the Global Burden of Disease Study 2016 (GBD 2016) were used. We evaluated the burden by analyzing age-sex-province-specific prevalence, mortality, and disability-adjusted life-years (DALYs) of 33 provinces in China. Results From 1990 to 2016, prevalence cases in thousands increased by 73.7% from 6833.3 (95% UI: 6498.0–7180.6) to 11869.6 (95% UI: 11274.6–12504.7). Age-standardized mortality and DALY rates per 100,000 decreased by 51.2% and 53.3%, respectively. Male and elderly people (aged ≥ 60 years) preponderance were found for prevalence, mortality, and DALYs. The number of prevalence cases, deaths, and DALYs due to hepatitis C virus (HCV) increased by 86.6%, 8.7%, and 0.9%, respectively. Also, age-standardized prevalence rates decreased in 31 provinces, but increased in Yunnan and Shandong. The Socio-demographic Index (SDI) values were negatively correlated with age-standardized mortality and DALY rates by provinces in 2016; the correlation coefficients were −0.817 and −0.828, respectively. Conclusion Cirrhosis and other chronic liver diseases remain a huge health burden in China, with the increase of population and the aging of population. Hepatitis B virus (HBV) remains the leading cause of the health burden in China.

Objective Assessment of the comprehensive relationship among apolipoprotein CIII (apoCIII) levels, inflammation, and metabolic disorders is rare. Methods A total of 1455 consecutive patients not treated with lipid-lowering drugs and undergoing coronary angiography were enrolled in this cross-sectional study. A mediation analysis was used to detect the underlying role of apoCIII in the association of inflammation with metabolic syndrome (MetS). Results Patients with MetS showed higher levels of apoCIII[95.1 (73.1-131.4) vs. 81.7 (58.6-112.4) μg/mL, P<0.001] and inflammatory markers[high sensitivity C-reactive protein, 1.7 (0.8-3.4) vs. 1.1 (0.5-2.2) mg/L; white blood cell count, (6.48±1.68) vs. (6.11±1.67)×109/L]. The levels of apoCIII and inflammatory markers increased with the number of metabolic risk components (all P<0.001). Furthermore, apoCIII levels were associated with virtually all individual MetS risk factors and inflammatory markers (all P<0.05). Importantly, the prevalence of MetS in each metabolic disorder rose as apoCIII levels increased (all P<0.05). Mediation analysis showed that apoCIII partially mediated the effect of inflammation on MetS independently from triglycerides. Conclusion Plasma apoCIII levels were significantly associated with the development and severity of MetS, and a role of apoCIII in the effect of inflammation on the development of MetS was identified.

Objective To investigate the effects of short-term forest bathing on human health.Methods Twenty healthy male university students participated as subjects and were randomly divided into two groups of 10.One group was sent on a two-night trip to a broad-leaved evergreen forest,and the other was sent to a city area.Serum cytokine levels reflecting inflammatory and stress response,indicators reflecting oxidative stress,the distribution of leukocyte subsets,and plasma endothelin-1 (ET-1) concentrations were measured before and after the experiment to evaluate the positive health effects of forest environments.A profile of mood states (POMS) evaluation was used to assess changes in mood states.Results No significant differences in the baseline values of the indicators were observed between the two groups before the experiment.Subjects exposed to the forest environment showed reduced oxidative stress and pro-inflammatory level,as evidenced by decreased malondialdehyde,interleukin-6,and tumor necrosis factor α levels compared with the urban group.Serum cortisol levels were also lower than in the urban group.Notably,the concentration of plasma ET-1 was much lower in subjects exposed to the forest environment.The POMS evaluation showed that after exposure to the forest environment,subjects had lower scores in the negative subscales,and the score for vigor was increased.Conclusion Forest bathing is beneficial to human health,perhaps through preventive effects related to several pathological factors.

Objective A subcutaneous transplantation tumor model of human HT-29 cells was established in nude mice to study the anticarcinogenic activities and apoptosis-regulatory mechanistic effect of aqueous extract of fermented barley with Lactobacillus plantarum dy-1 (LFBE). Methods HT-29 cells were transplanted via subcutaneous injection of 1×107 cells into the right flank of each nude mouse. Then, nude mice were treated for 30 days with LFBE (high-dose 2 g·kg-1·d-1; low-dose 1 g·kg-1·d-1) and for 7 days with 5-fluorouracil (5-FU, 25 g·kg-1·d-1) by gavage and intraperitoneal injection, respectively. Results Tumor volume and weight decreased significantly in both groups of nude mice treated with LFBE. In addition, the cell apoptosis rate of the LFBE group was significantly higher than that of the control group and 5-FU groups as measured by the TUNEL assay. Moreover, the real-time fluorescent quantitative PCR and Western blot methods further confirmed these apoptosis-enhancing and growth-inhibiting effects. The involvement of LFBE in inducing apoptosis was confirmed by the expression of Bax, Bcl-2, caspase-3, and cyclinD1. Conclusion The results showed that LFBE could induce subcutaneous transplantation tumor apoptosis in nude mice and could be used as a natural nutrient supplement or chemopreventive agent in the treatment of human colon cancer.

Abstract: Infectious diseases are an enormous public health burden and a growing threat to human health worldwide. Emerging or classic recurrent pathogens, or pathogens with resistant traits, challenge our ability to diagnose and control infectious diseases. Nanopore sequencing technology has the potential to enhance our ability to diagnose, interrogate, and track infectious diseases due to the unrestricted read length and system portability. This review focuses on the application of nanopore sequencing technology in the clinical diagnosis of infectious diseases and includes the following: (i) a brief introduction to nanopore sequencing technology and Oxford Nanopore Technologies (ONT) sequencing platforms; (ii) strategies for nanopore-based sequencing technologies; and (iii) applications of nanopore sequencing technology in monitoring emerging pathogenic microorganisms, molecular detection of clinically relevant drug-resistance genes, and characterization of disease-related microbial communities. Finally, we discuss the current challenges, potential opportunities, and future outlook for applying nanopore sequencing technology in the diagnosis of infectious diseases.

Objective To evaluate the effect of intense pulsed light (IPL) in the treatment of chronic hordeolum. Methods Patients with chronic hordeolum who underwent IPL treatment were enrolled in this study. According to the severity of hordeolum, the patients were treated with IPL 3 to 5 times. Patients' satisfaction and visual analog scale scores for ocular discomfort symptoms before and after treatment were collected. The number, congestion, long diameter, short diameter and area of nodules were also recorded and measured. Finally, eyelid margin signs, meibum quality, meibomian gland expressibility, meibomian gland dropout, tear meniscus height, and corneal fluorescein staining were scored. Results 20 patients were enrolled in this study. The eyelid margins were congestive and swollen, with blunt rounding or irregularity. The meibum was cloudy or toothpaste-like. The meibomian gland expressibility, meibomian gland dropout and tear meniscus height were reduced. The cornea showed scattered fluorescein staining. After treatment, score of visual analog scale, congestion and size of nodules were significantly reduced. Eyelid margin signs, meibum quality, meibomian gland expressibility, tear meniscus height and corneal fluorescein staining scores were improved. Meibomian gland dropout had no significant change. No side effects occurred during treatment. Conclusions IPL is beneficial for the treatment of chronic hordeolum.

Objective This study aimed to evaluate the effects of a mindfulness-based psychosomatic intervention on depression, anxiety, fear of childbirth (FOC), and life satisfaction of pregnant women in China. Methods Women experiencing first-time pregnancy (n = 104) were randomly allocated to the intervention group or a parallel active control group. We collected data at baseline (T0), post-intervention (T1), 3 days after delivery (T2), and 42 days after delivery (T3). The participants completed questionnaires for the assessment of the levels of depression, anxiety, FOC, life satisfaction, and mindfulness. Differences between the two groups and changes within the same group were analyzed at four time points using repeated-measures analysis of variance. Results Compared with the active control group, the intervention group reported lower depression levels at T2 (P = 0.038) and T3 (P = 0.013); reduced anxiety at T1 (P = 0.001) and T2 (P = 0.003); reduced FOC at T1 (P < 0.001) and T2 (P = 0.04); increased life satisfaction at T1 (P < 0.001) and T3 (P = 0.015); and increased mindfulness at T1 (P = 0.01) and T2 (P = 0.006). Conclusion The mindfulness-based psychosomatic intervention effectively increased life satisfaction and reduced perinatal depression, anxiety, and FOC.

Objective To detect Japanese encephalitis virus (JEV) rapidly and distinguish its genotypes, a TaqMan-based reverse transcriptase quantitative polymerase chain reaction (RT-PCR) detection system was developed. Methods By aligning the full-length sequences of JEV (G1-G5), six sets of highly specific TaqMan real-time RT-PCR primers and probes were designed based on the highly conserved NS1, NS2, and M genes of JEV, which included one set for non-specific JEV detection and five sets for the detection of specific JEV genotypes. Twenty batches of mosquito samples were used to evaluate our quantitative PCR assay. Results With the specific assay, no other flavivirus were detected. The lower limits of detection of the system were 1 pfu/mL for JEV titers and 100 RNA copies/μL. The coefficients of variation of this real-time RT-PCR were all < 2.8%. The amplification efficiency of this method was between 90% and 103%. Conclusion A TaqMan real-time RT-PCR detection system was successfully established to detect and differentiate all five JEV genotypes.

Objective Preliminary assessment of rabies virus neutralizing activity, safety and immunogenicity of a recombinant human rabies antibody (NM57) compared with human rabies immunoglobulin (HRIG) in Chinese healthy adults. Methods Subjects were randomly (1:1:1) allocated to Groups A (20 IU/kg NM57), B (40 IU/kg NM57), or C (20 IU/kg HRIG). One injection was given on the day of enrollment. Blood samples were collected on days −7 to 0 (pre-injection), 3, 7, 14, 28, and 42. Adverse events (AEs) and serious AEs (SAEs) were recorded over a period of 42 days after injection. Results All 60 subjects developed detectable rabies virus neutralizing antibodies (RVNAs) (> 0.05 IU/mL) on days 3, 7, 14, 28, and 42. The RVNA levels peaked on day 3 in all three groups, with a geometric mean concentration (GMC) of 0.2139 IU/mL in Group A, 0.3660 IU/mL in Group B, and 0.1994 IU/mL in Group C. At each follow-up point, the GMC in Group B was significantly higher than that in Groups A and C. The areas under the antibody concentration curve over 0–14 days and 0–42 days in Group B were significantly larger than those in Groups A and C. Fifteen AEs were reported. Except for one grade 2 myalgia in Group C, the other 14 were all grade 1. No SAEs were observed. Conclusion The rabies virus neutralizing activity of 40 IU/kg NM57 was superior to that of 20 IU/kg NM57 and 20 IU/kg HRIG, and the rabies virus neutralizing activity of 20 IU/kg NM57 and 20 IU/kg HRIG were similar. Safety was comparable between NM57 and HRIG.

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.

Objective MicroRNAs (miRs) are attractive molecules to be considered as one of the blood-based biomarkers for neurodegenerative disorders such as Alzheimer's disease (AD). The goal of this study was to explore their potential value as biomarkers for the diagnosis of AD. Methods The expression levels of exosomal miR-135a, -193b, and-384 in the serum from mild cognitive impairment (MCI), dementia of Alzheimer type (DAT), Parkinson's disease with dementia (PDD), and vascular dementia (VaD) patients were measured with a real-time quantitative reverse transcriptase PCR (qRT-PCR) method. Results Both serum exosome miR-135a and miR-384 were up-regulated while miR-193b was down-regulated in serum of AD patients compared with that of normal controls. Exosome miR-384 was the best among the three miRs to discriminate AD, VaD, and PDD. Using the cut-off value could better interpret these laboratory test results than reference intervals in the AD diagnosis. ROC curve showed that the combination of miR-135a, -193b, and-384 was proved to be better than a particular one for early AD diagnosis. Conclusion Our results indicated that the exosomal miRs in the serum were not only potential biomarker of AD early diagnosis, but might also provide novel insights into the screen and prevention of the disease.
