Objective:To explore the current therapeutic status of rhythm control versus rate control in elderly patients with atrial fibrillation(AF)and the related factors that may influence treatment decisions.Methods:A retrospective study was conducted on AF patients aged ≥75 years old who were hospitalized in the Healthcare Department of Beijing Hospital from January 2010 to May 2020.The patients were grouped and compared according to whether they underwent rhythm control or rate control.Multivariate logistic regression analysis was used to investigate the factors that may influence the treatment decision of rhythm control or rate control.Results:A total of 167 patients was included, with a median age of 90 years old.Among them, 21 patients(12.6%)received rhythm control, and 109 patients(65.3%)received rate control.Compared with the group not receiving rhythm control, the rhythm control group had a younger age, higher BMI, higher diastolic blood pressure, a higher proportion of multiple medication use, a lower proportion of chronic kidney disease stage 3 or above, and higher hemoglobin levels(all P<0.05). Compared with the group not receiving rate control, the rate control group had a lower proportion of paroxysmal AF, a faster resting ventricular rate, a higher proportion of smoking history, a higher proportion of multiple medication use, coronary heart disease, pacemaker treatment, chronic obstructive pulmonary disease and/or asthma, and a lower proportion of cognitive impairment(all P<0.05). Multivariate logistic regression analysis revealed that multiple drug use( OR=11.578, 95% CI: 1.341-99.993, P=0.026)was positively associated with rhythm control therapy, while chronic kidney disease stage 3 or above( OR=0.248, 95% CI: 0.063-0.968, P=0.045)was negatively associated with rhythm control therapy.For rate control therapy, multiple drug use( OR=5.056, 95% CI: 2.253-11.347, P<0.001), resting ventricular rate( OR =1.033, 95% CI: 1.005-1.062, P=0.021), and chronic obstructive pulmonary disease(COPD)and/or asthma( OR=2.739, 95% CI: 1.124-6.672, P=0.027)showed positive associations. Conclusions:The application rate of rhythm control therapy is low in elderly AF patients, and ventricular rate control is the main treatment.Complex clinical conditions are the main constraints, and it is urgent to optimize individualized strategies based on prospective studies and develop new treatment techniques to improve clinical practice.

Objective The study aimed to investigate the predictive efficacy of contrast-enhanced ultrasound combined with telomerase reverse transcriptase(TERT)promoter mutation in constructing nomogram model for the prediction of concomitant cervical lymph node metastasis(CLNM)in papillary thyroid microcarcinoma(pTMC).Methods A total of 202 patients with pTMC who underwent partial or total thyroidectomy+lymph node dissection at our hospital from January 2021 to March 2024 were selected.Then,they were divided into the CLNM group(97 patients)and the non-CLNM group(105 patients)according to whether they had concomitant CLNM on postoperative pathological examination.General data and ultrasound(conventional ultrasound and contrast-enhanced ultrasound)characteristics were collected from all patients with pTMC,and Sanger sequencing was used to detect TERT promoter mutations.The influencing factors of pTMC complicated by CLNM were analyzed by single-factor and multifactorial unconditional logistic regression;the nomogram model of pTMC complicating CLNM with contrast-enhanced ultra-sound combined with TERT promoter mutation was constructed by RStudio 4.4.1 software,and the consistency and net benefit of the nomogram model were evaluated by using calibration curves,decision curves,and C-indexes,and the Hosmer-Lemeshow test for goodness of fit of the nomogram model;The predictive efficiency of the nomogram model constructed by combining contrast-enhanced ultrasound and TERT promoter mutation for pTMC complicated by CLNM was evaluated by plotting receiver operating characteristic(ROC)curves using MedCalc22.023 software.Results After postoperative pathological examination,the incidence of CLNM in 202 patients with pTMC was 48.02%(97/202).Univariate analysis showed that thyroglobulin antibodies,number of lesions,aspect ratio,micro-calcifications,enhancement time,enhancement mode,enhancement intensity,capsular continuity,and TERT promoter mutations were associated with pTMC complicating CLNM(P<0.05).Multifactorial unconditional logistic regression showed that multifocal tumours(OR=3.487,95%CI:1.641～7.406,P=0.001),microcalcifications(OR=4.484,95%CI:2.113～9.516,P<0.001),equal or high enhancement(OR=3.187,95%CI:1.460～6.957,P=0.004),disruption of peritoneal continuity(OR=2.201,95%CI:1.051～4.608,P=0.036),and TERT promoter mutation positivity(OR=4.460,95%CI:2.132～10.103,P<0.001)were the independent risk factors for pTMC complicating CLNM.A contrast-enhanced ultrasound combined TERT promoter mutation nomogram model was constructed based on independent risk factors for pTMC complicating CLNM[Logit(p)=-4.486+1.350×number of foci+1.399×microcalcifications+2.124×intensity of enhancement+1.524×capsular continuity+2.175×TERT promoter mutations].The C-index of this nomogram model was 0.899(95%CI:0.893～0.905),the calibra-tion curve alignment was close to the ideal curve,the decision curve was higher than the two extreme curves,and the Hosmer-Lemeshow test showed a P>0.05.The ROC curve analysis showed that the nomogram model constructed with contrast-enhanced ultrasound combined with TERT promoter mutations predicted CLNM in pTMC with an area under the curve of 0.899.This was significantly higher than the area under the curves for contrast-enhanced ultra-sound alone(0.857)and TERT promoter mutations alone(0.697)(P<0.05).Conclusion The contrast-enhanced ultrasound combined with TERT promoter mutations to construct a nomogram model has high predictive efficiency for pTMC complicating CLNM.

Objective:To explore the mechanism by which Pien Tze Huang improves liver Kupffer cell damage induced by lipopolysaccharide (LPS) by regulating the expression of miR-155.Methods:LPS induced liver Kupffer cells to establish a cell injury model to simulate septic liver injury. RT-qPCR was used to detect the expression of miR-155 in damaged cells, and RT-qPCR, Western Blot, ELISA and flow cytometry were used to evaluate the inflammatory response and apoptosis of damaged cells. Then we treated LPS-induced Kupffer cells with Pien Tze Huang at different concentrations (0 mg/L, 5 mg/L, 10 mg/L and 15 mg/L), and detected the expression of miR-155 in the cells, the inflammatory response of the cells and Apoptosis rate. MiR-155 was silenced in the cell injury model, and RT-qPCR, Western Blot, ELISA and flow cytometry were used to evaluate the effect of miR-155 on inflammatory response and apoptosis of model cells. Overexpression of miR-155 in damaged cells treated with Pien Tze Huang was used to detect changes in cellular inflammatory response and apoptosis. Data are expressed in the form of mean ± standard deviation, and each group of data is analyzed using t test or one-way analysis of variance.Results:In the LPS-induced liver Kupffer cell injury model, the expression of miR-155 was significantly increased ( P<0.05), the expression levels of pro-inflammatory factors IL-6 and TNF-α were significantly increased, and the anti-inflammatory factor IL-10 was significantly increased. was inhibited ( P<0.05), and the cell apoptosis rate was significantly increased ( P<0.05). After Pien Tze Huang treatment, the expression of miR-155 in damaged liver cells was inhibited ( P<0.05), the levels of cellular inflammatory factors IL-6 and TNF-α were inhibited, and the expression of anti-inflammatory factor IL-10 was promoted ( P<0.05). Inhibit cell apoptosis ( P<0.05). Silencing miR-155 reduced the inflammatory response and apoptosis rate of cells ( P<0.05). Overexpression of miR-155 can reverse the effect of Pien Tze Huang on liver cell injury ( P<0.05). Conclusions:In the model of LPS-induced liver Kupffer cell injury, Pien Tze Huang can inhibite the inflammatory response and apoptosis of cells by inhibiting the expression of miR-155.

Aromatic compounds are a class of organic compounds with benzene ring(s). Aromatic compounds are hardly decomposed due to its stable structure and can be accumulated in the food cycle, posing a great threat to the ecological environment and human health. Bacteria have a strong catabolic ability to degrade various refractory organic contaminants (e.g., polycyclic aromatic hydrocarbons, PAHs). The adsorption and transportation are prerequisites for the catabolism of aromatic compounds by bacteria. While remarkable progress has been made in understanding the metabolism of aromatic compounds in bacterial degraders, the systems responsible for the uptake and transport of aromatic compounds are poorly understood. Here we summarize the effect of cell-surface hydrophobicity, biofilm formation, and bacterial chemotaxis on the bacterial adsorption of aromatic compounds. Besides, the effects of outer membrane transport systems (such as FadL family, TonB-dependent receptors, and OmpW family), and inner membrane transport systems (such as major facilitator superfamily (MFS) transporter and ATP-binding cassette (ABC) transporter) involved in the membrane transport of these compounds are summarized. Moreover, the mechanism of transmembrane transport is also discussed. This review may serve as a reference for the prevention and remediation of aromatic pollutants.

Objective:To investigate the changes in gut microbiota diversity with age in elderly people using high-throughput sequencing.Methods:Ninety healthy volunteers were recruited. People who were <60 years old (middle-aged group) were set up as a baseline control group (Age A group), while those aged ≥60 years old were further divided into four groups (60-<70: Age B group, 70-<80: Age C group, 80-<90: Age D group, ≥90: Age E group). Fecal samples were collected to extract DNA. The second-generation sequencing technology was used to amplify and sequence the V3-V4 hypervariable region of 16S rDNA. Bioinformatics analysis was performed to compare the differences in gut microbiota and functional genes among groups.Results:At the phylum level, gut microbiota were composed mainly of Firmicute, Bacteroidetes, Proteobacteria and Actinobacteria in different groups. The proportion of Firmicute was the highest, accounting for over 60%, followed by that of Bacteroidetes. At the genus level, the abundance of Faecalibacterium genus decreased with age. The α diversity analysis showed that the gut microbiota in the elderly of different ages had higher abundance and uniformity, and there was no significant difference among groups. However, the β diversity analysis showed that in community structure there was difference between Age A and Age B groups, and similarity between Age B and Age C groups. Conclusions:The community structure of gut microbiota changed significantly between young and middle-aged people and the elderly over 60 years old. It tended to be relatively stable in people of 60-80 years old, but changed again when they were over 80 years old. Chronic inflammatory diseases, metabolic diseases and tumors in the elderly might be associated with the decrease in Faecalibacterium.

Objective:To implement PRECEDE-PROCEED based intervention in community patients with type 2 diabetes mellitus (T2DM) and explore its effects on patients' diabetes knowledge and self-efficacy.Methods:Totally 86 T2DM patients treated in a community health service center in Hangzhou between May and October 2014 were selected using convenient sampling and divided into intervention group ( n=43) and control group ( n=43) . Patients in the intervention group received 6-month intervention based on PRECEDE-PROCEED, while patients in the control group received a regular community health education course once during the same period. The diabetes knowledge and self-efficacy scores were evaluated between the two groups before and 3 and 6 months after intervention. At last, a total of 40 patients in the intervention group and 42 patients in the control group completed the study. Results:Repeated measures analysis of variance showed that there were time-dependent, between-group and combined effects in diabetes knowledge and self-efficacy scores in the two groups ( P<0.05) . Pairwise comparison between the two groups revealed that there was no statistically significant difference in diabetes knowledge and self-efficacy scores between the two groups before intervention ( P>0.05) , but there were statistically significant differences in diabetes knowledge and self-efficacy scores between the two groups 3 and 6 months after intervention ( P<0.05) . Conclusions:The PRECEDE-PROCEED based intervention can effectively improve the diabetes knowledge and self-efficacy of T2DM patients, which is worth promoting in clinical practice.
