Objective: To investigate the self-monitoring blood pressure behavior and its influencing factors among residents in Jiangsu Province, so as to provide the basis for strengthening proactive blood pressure monitoring among residents. Methods: Permanent residents aged 35-75 years in six counties (cities, districts), Jiangsu Province, were selected using the stratified cluster sampling method in 2023. Data on basic information, disease history, and self-monitoring blood pressure behavior were collected, height and weight were measured to calculate the body mass index (BMI); and blood glucose and lipid levels were measured. Self-monitoring blood pressure behavior was defined as having measured blood pressure at least once in the past three months. Factors affecting self-monitoring blood pressure behavior were identified using a multivariable logistic regression model. Results: A total of 12 475 residents were surveyed, including 5 748 males and 6 727 females, with a male-to-female ratio of 1∶1.17. There were 3 855 residents aged 45-<55 years (30.90%) and 5 511 residents who had self-monitoring blood pressure behaviors (44.18%). Multivariable logistic regression analysis showed that the residents who were males (OR=1.167, 95%CI: 1.081-1.261), lived in rural areas (OR=1.430, 95%CI: 1.321-1.547), aged 45-75 years (45-<55 years, OR=1.384, 95%CI: 1.241-1.543; 55-<65 years, OR=1.397, 95%CI: 1.243-1.570; 65-75 years, OR=1.196, 95%CI: 1.049-1.363), had an annual household income ≥30 000 yuan (30 000-<60 000 yuan, OR=1.190, 95%CI: 1.072-1.321; 60 000-<110 000 yuan, OR=1.330, 95%CI: 1.191-1.485; ≥110 000 yuan, OR=1.746, 95%CI: 1.536-1.984), were overweight (OR=1.170, 95%CI: 1.070-1.280) or obese (OR=1.248, 95%CI: 1.120-1.391), were unaware (OR=1.221, 95%CI: 1.103-1.353) or aware (OR=3.937, 95%CI: 3.575-4.335) of having hypertension, were aware of having diabetes (OR=1.538, 95%CI: 1.354-1.749), and aware of having dyslipidemia (OR=1.265, 95%CI: 1.106-1.447) were more likely to have self-monitoring blood pressure behaviors. Conclusions Among the residents aged 35-75 years in Jiangsu Province, 44.18% had self-monitoring blood pressure behavior. Gender, place of residence, age, annual household income, BMI, hypertension, diabetes, and dyslipidemia were identified as influencing factors for self-monitoring blood pressure behavior.

Chinese hamster ovary (CHO) cells play an irreplaceable role in biopharmaceuticals because the cells can be adapted to grow in suspension cultures and are capable of producing high quality biologics exhibiting human-like post-translational modifications. However, gene expression regulation such as transgene silencing and epigenetic modifications may reduce the recombinant protein production due to the decrease of expression stability of CHO cells. This paper summarized the role of epigenetic modifications in CHO cells, including DNA methylation, histone modification and miRNA, as well as their effects on gene expression regulation.

Polymerase chain reaction (PCR) is the gold standard for nucleic acid amplification in molecular diagnostics. The PCR includes multiple reaction stages (denaturation, annealing, and extension), and a complicated thermalcycler is required to repetitively provide different temperatures for different stages for 30-40 cycles within at least 1-2 hours. Due to the complicated devices and the long amplification time, it is difficult to adopt conventional PCR in point-of-care testing (POCT). Comparing to conventional PCR, isothermal amplification is able to provide a much faster and more convenient nucleic acid detection because of highly efficient amplification at a constant reaction temperature provided by a simple heating device. When isothermal amplification is combined with microfluidics, a more competent platform for POCT can be established. For example, various diagnosis devices based on isothermal amplification have been used to rapidly and conveniently detect SARS-CoV-2 viruses. This review summarized the recent development and applications of the microfluidics-based isothermal amplification. First, different typical isothermal amplification methods and related detection methods have been introduced. Subsequently, different types of microfluidic systems with isothermal amplification were discussed based on their characteristics, for example, functionality, system structure, flow control, and operation principles. Furthermore, detection of pathogens (e.g. SARS-CoV-2 viruses) based on isothermal amplification was introduced. Finally, the combination of isothermal amplification with other new technologies, e.g. CRISPR, has been introduced as well.

Objective:To explore the effect of neutrophil-lymphocyte ratio (NLR) at the initial visit on the survival of children with newly diagnosed medulloblastoma (MB).Methods:This was a case-control study involving 61 children with newly diagnosed MB at the Department of Pediatrics, Beijing Shijitan Hospital, Capital Medical University from August 2018 to January 2020 .The blood cell counts, lymphocyte subsets and immunoglobulin in the periphe-ral blood were measured to calculate NLR at the initial visit.Based on the cut-off value determined by receiver opera-ting characteristic (ROC) curve, patients were divided into high NLR group (≥ 2.07, n=21) and low NLR group (<2.07, n=40). The progression-free survival (PFS) and overall survival (OS) between 2 groups were analyzed by the Kaplan-Meier method, followed by Log- rank test.The correlation between NLR at the initial visit with clinical characteristics, lymphocyte subsets and immunoglobulin of children with newly diagnosed MB was analyzed.Differences between groups were compared by the Chi- square test, Mann- Whitney U test and independent sample t test. Results:The survival analysis showed that the relapse rate (38.1% vs.10.0%, χ2=6.879, P=0.016) and mortality rate (19.0% vs.0, χ2=8.154, P=0.011) were significantly higher in high NLR group than those of low NLR group.PFS (12 months vs.19 months, χ2=9.775, P=0.002) and OS (19 months vs.20 months, χ2=8.432, P=0.004) were significantly shorter in high NLR group than those of low NLR group.No significant differences in clinical characteristics were detected between groups (all P>0.05). Compared with low NLR group, the percentage of T lymphocyte[(67.93±6.37)% vs.(73.38±8.08)%, t=2.886, df=48.865, P=0.006], T helper cells (Th)[(30.86±5.53)% vs.(34.29±7.44)%, t=2.037, df=51.981, P=0.047], and T suppressor cells (Ts)[(27.39±5.50)% vs.(30.84±6.58)%, t=2.164, df=47.581, P=0.035] were significantly lower in high NLR group.Spearman correlation analysis showed a negative correlation between NLR and T lymphocyte count ( r=-0.303, P=0.018), and Ts lymphocyte count ( r=-0.260, P=0.043). Conclusions:Children with newly diagnosed MB expressing a high level of NLR had a poor prognosis, which may be associated with T lymphocyte and Ts lymphocyte.
