Guided by the theories of yin-yang and collateral disease, this paper identifies the dysregulation of yang qi ascent and descent as the core pathomechanism of hypertension. Based on clinical experience, a treatment approach centered on the method of raising yang and promoting descent was proposed. Clinically, three major syndrome types were identified. Firstly, deficiency of zong qi (ancestral qi) with blood stasis, obstruction of phlegm-turbidity and blood stasis, and hyperactivity of liver yang. Corresponding empirical formulation, Yizong Huoxue Decoction (益宗活血汤) was applied to tonify zong qi, invigorate blood, and raise yang. Secondly, Lizong Huoxue Decoction (理宗活血汤) was used to resolve phlegm, promote yang qi circulation, and regulate qi and blood. Thirdly, Qinggan Tongluo Decoction (清肝通络饮) was used to clear the liver, dredge collaterals, and subdue hyperactive yang. For special types such as non-dipper hypertension, time-specific syndrome differentiation and treatment can be applied based on a thorough understanding of the underlying pathomechanism, aiming to provide new insights into clinical diagnosis and treatment of hypertension.

Chronic heart failure (CHF) is a complex clinical syndrome that the cardiac output is not enough to meet the metabolic needs of the body, or depends on the increase of filling pressure to compensate. Its high morbidity and mortality pose a serious threat to human health, necessitating attention and active intervention. At present, western medicine treatment of CHF is mainly based on diuretics, intravenous vasodilators, intravenous positive inotropic drugs, etc., which, however, have problems such as long medication cycles, serious side effects, and limited applicable population. Recent studies have shown that traditional Chinese medicine can act in a multi-pathway, multi-component, and multi-target manner, showing unique advantages in the prevention and treatment of CHF. Buyang Huanwutang has the effects of tonifying Qi, activating blood, and dredging collaterals. Clinical and mechanism studies have confirmed that this prescription is effective in treating CHF and its syndromes. The clinical studies can be classified into two categories. Studies of the first category use simple modern medical diagnostic criteria as the inclusion criteria for CHF patients, which can improve the scientificity and objectivity. Studies of the second category uses modern medicine combined with traditional Chinese medicine disease diagnostic criteria for the screening of CHF patients, which helps to improve the accuracy of efficacy evaluation. However, there are problems such as the lack of unified research standards and the insufficiency of mechanism research. In addition, the available studies remain to be classified or summarized. This study systematically sorted out the clinical and mechanism studies of Buyang Huanwutang in the treatment of CHF in recent years to review the research status. In clinical treatment, Buyang Huanwutang can be used alone, or modified, or combined with other prescriptions or Western medicine. The mechanism studies predict that Buyang Huanwutang can ameliorate CHF by regulating the calcium balance, protecting the mitochondrial structure and function, and regulating intestinal flora. This review aims to provide a theoretical basis and practical guidance for the clinical application and optimization and subsequent in-depth study of Buyang Huanwutang in the treatment of CHF.

Background Animal farming may affect the structure and diversity of gut microbiota of farm workers, but it needs more studies to provide solid evidence. Objective To analyze the diversity characteristics of gut microbiota in dairy farm workers, dairy cows, and the control population (non-animal contact occupational group), and to assess the impact of dairy farming on the gut microbiota of workers. Methods The 16S rRNA full-length amplicon sequencing technology was used to sequence 60 fecal samples from dairy farm workers, 89 from dairy cows, and 50 from the general population. The gut microbiota structure characteristics, including operational taxonomic units (OTUs), alpha diversity, beta diversity, and the composition of species at the phylum, family, and genus levels were analyzed. The differences in gut microbiota among the three groups of samples were compared to explore the impact of occupational exposure on the gut microbiota structure of dairy farm workers.

Objective To identify long non-coding RNA (lncRNA) associated with rheumatoid arthritis-associated interstitial lung disease (RA-ILD) and investigate their mechanisms. Methods Peripheral blood samples were collected from RA-ILD patients (n=3), RA patients without lung involvement (n=3), and healthy controls (n=3). Next-generation sequencing was performed to screen differentially expressed lncRNA. A human fibrotic lung cell model was established by inducing the MRC-5 cell line with transforming growth factor-β (TGF-β). Following siRNA-mediated knockdown of target genes, changes in inflammatory and oxidative stress-related genes were analyzed via real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR). Western blotting and dual-luciferase reporter (DLR) assays were used to validate protein expression, ubiquitination levels, and nuclear translocation of oxidative stress regulators, and antioxidant response element (ARE) transcriptional activity. Rescue experiments were conducted to confirm the role of target lncRNA in oxidative stress and inflammation in fibrotic lung cells. Results High-throughput sequencing revealed significant downregulation of LINC00638 in RA-ILD patients. Knockdown of LINC00638 markedly reduced transcriptional levels of interleukin (IL)-4, nuclear factor erythroid-2-related factor 2 (Nrf2), heme oxygenase-1 (HO-1), and superoxide dismutase 2 (SOD2), while increasing IL-6, IL-1β, interferon-γ (IFN-γ), and reactive oxygen species (ROS) levels. Furthermore, LINC00638 knockdown decreased Nrf2 protein expression, increased its ubiquitination, reduced nuclear translocation, and suppressed ARE transcriptional activity. In MRC-5 cells, LINC00638 knockdown combined with N-acetylcysteine treatment restored Nrf2 and HO-1 levels while reducing IL-6 expression. Conclusions LINC00638 suppresses inflammatory responses in RA-ILD by activating the Nrf2/ARE antioxidant signaling pathway, suggesting its potential as a therapeutic target for diagnosis and treatment.

Objective:To evaluate the value of 18F-FDG PET/CT for preoperative localization of epileptogenic foci in refractory epilepsy patients with negative MRI. Methods:Clinical data (550 lobes) of 55 epilepsy patients (38 males, 17 females, age (20.0±8.1) years) with negative MRI who underwent preoperative 18F-FDG PET/CT-MRI between January 2014 and June 2020 at the First Affiliated Hospital of Jinan University were retrospectively analyzed. The sensitivity, specificity, accuracy, positive predictive value (PPV) and negative predictive value (NPV) of 18F-FDG PET/CT, video electroencephalogram (VEEG), PET/CT+ VEEG and PET/CT-VEEG for localizing epileptogenic foci were calculated using stereoelectroencephalography (SEEG) and the outcomes of at least 1 year of postoperative follow-up as reference standards. χ2 test was used to compare the efficiencies of different examination modalities for unilobar, multilobar and all patients. Results:The correct lateralization rate of epileptogenic foci was 92.6%(25/27) using PET/CT. The sensitivity, specificity, accuracy, PPV and NPV of PET/CT for localization of epileptogenic foci were 65.1%(54/83), 77.9%(364/467), 76.0%(418/550), 34.4%(54/157) and 92.6%(364/393), respectively. The sensitivities of PET/CT-VEEG for localization of epileptogenic foci in all patients and patients with multilobar epilepsy were higher than those of VEEG alone (75.9%(63/83) vs 45.8%(38/83), 68.6%(35/51) vs 31.4%(16/51); χ2 values: 15.80, 14.16, both P<0.001). The specificities of PET/CT+ VEEG for localization of epileptogenic foci in all patients and patients with unilobar epilepsy were higher than those of VEEG alone (97.6%(456/467) vs 94.6%(442/467), 97.9%(282/288) vs 94.1%(271/288); χ2 values: 5.66, 5.48; P values: 0.017, 0.019). The sensitivity of PET/CT-VEEG (PET/CT and VEEG concordance) for localization of epileptogenic foci was higher than that of PET/CT+ VEEG (PET/CT and VEEG discordance) (8/9 vs 28.4%(21/74); χ2=10.40, P=0.001), and its specificity and accuracy were higher than those of PET/CT-VEEG (PET/CT and VEEG discordance) (93.4%(57/61) vs 71.7%(291/406), 92.9%(65/70) vs 72.1%(346/480); χ2 values: 13.23, 13.96; both P<0.001). Conclusions:18F-FDG PET/CT can localize and lateralize epileptogenic foci in patients with negative MRI. The combination of 18F-FDG PET/CT and VEEG improves the sensitivity, specificity, and accuracy for epileptogenic foci detection. 18F-FDG PET/CT is more accurate in detecting epileptogenic foci when it is concordant with VEEG.

Objective:To predict the short-term postoperative recurrence status of patients with refractory temporal lobe epilepsy (TLE) by analyzing preoperative 18F-FDG PET images and patients′ clinical characteristics based on deep residual neural network (ResNet). Methods:Retrospective analysis was conducted on preoperative 18F-FDG PET images and clinical data of 220 patients with refractory TLE (132 males and 88 females, age 23.0(20.0, 30.2) years)) in the First Affiliated Hospital of Jinan University between January 2014 and June 2020. ResNet was used to perform high-throughput feature extraction on preprocessed PET images and clinical features, and to perform a postoperative recurrence prediction task for differentiating patients with TLE. The predictive performance of ResNet model was evaluated by ROC curve analysis, and the AUC was compared with that of classical Cox proportional risk model using Delong test. Results:Based on PET images combined with clinical feature training, AUCs of the ResNet in predicting 12-, 24-, and 36-month postoperative recurrence were 0.895±0.073, 0.861±0.058 and 0.754±0.111, respectively, which were 0.717±0.093, 0.697±0.081 and 0.645±0.087 for Cox proportional hazards model respectively ( z values: -3.00, -2.98, -1.09, P values: 0.011, 0.018, 0.310). The ResNet showed best predictive effect for recurrence events within 12 months after surgery. Conclusion:The ResNet model is expected to be used in clinical practice for postoperative follow-up of patients with TLE, helping for risk stratification and individualized management of postoperative patients.

Objective:To analyze the changes of fasting plasma glucose(FPG)level before and after menopause.Methods:Kailuan health checkup cohort was used to extract data of women aged≥18 years who participated in the first physical examination of Kailuan physical examination cohort and had menopausal age at the end of the seventh physical examination. A total of 3 749 women with 22 057 physical examination records were included in the analysis. Natural logarithmic transformation was applied to FPG, and a segmented linear mixed-effects model was used to analyze the changes in ln-transformed FPG before and after menopause. Additionally, an interaction analysis was performed to assess the multiplicative effect of baseline age and baseline body mass index(BMI)on ln-transformed FPG concerning pre- and post-menopausal periods.Results:The average age of the first physical examination for women in this study was (45.63±4.52)years, the median menopausal age was 51(50~53)years, and the median number of physical examinations was 6(5~7)times. The results of the piecewise linear mixed effect model showed that lnFPG increased from 1 year before menopause, with an average annual increase of 0.021 mmol/L, and continued to increase from menopause to 5 years after menopause, with an average annual increase of 0.007 mmol/L. LnFPG tended to be stable after 5 years of menopause. Baseline age could affect the changes of lnFPG before and after menopause, and there was a negative multiplicative interaction between baseline age ≥45 years and the time period from 6 years to 1 year before menopause( P=0.032). Women with baseline age ≥45 years had a higher average annual increase in lnFPG from 1 year before menopause to 5 years after menopause than women with baseline age <45 years( P<0.05). On lnFPG, there was a positive multiplicative interaction between baseline BMI and time segments around menopause. Compared to women with BMI <24.0 kg/m 2, obese women displayed more annual increase in lnFPG from 6 years to 1 year before menopause as well as from menopause to 5 years after menopause( P<0.05). Conclusions:Menopause has an adverse impact on FPG, with the most significant changes occurring within the period of one year before menopause and up to five years after menopause. Age and BMI significantly influence the changes in FPG before and after menopause.

Objective:To assess the association between short-term ambient air pollution exposure and arterial stiffness and whether obesity modifies these associations.Methods:A cross-sectional study was conducted based on Fangshan family cohort in Beijing. The 24 hours average air pollutant levels on the day cohort participants took baseline survey were calculated as short-term air pollution. A generalized additive model (GAM) with Gaussian links was used to estimate changes in typical carotid artery intima-media thickness (CIMT), brachial-ankle pulse wave velocity (BAPWV), pulse pressure (PP) and ankle-branchial index (ABI) after short-term exposure to each air pollution (PM 2.5, PM 10, SO 2, NO 2, CO). The cross-product terms of each air pollution, body mass index (BMI), and waist-to-hip ratio were included in the GAM model to test the interaction. Further, they conducted a stratified analysis to test their effects on the relationship between short-term exposure to each air pollution and the arterial stiffness indicators. Results:A total of 4 211 individuals were included in the analysis. Individuals' age was (58.9±8.7) years, of which 2 268 (53.9%) were female. Several covariates, including sociodemographic factors, lifestyle behaviors, and history of drugs, were included in the analysis. The results of the GAM analysis showed that an increase in PM 2.5 ( β=2.912×10 -4, 95% CI: 1.424×10 -4-4.400×10 -4, P<0.001), CO ( β=0.027, 95% CI: 0.011-0.043, P<0.001), SO 2 ( β=2.070×10 -3, 95% CI: 7.060×10 -4-3.430×10 -3, P=0.003), and NO 2 ( β=3.650×10 -4, 95% CI: 2.340×10 -5-7.060×10 -4, P=0.036) were associated with an increase in CIMT, while an increase in PM 10 ( β=0.018, 95% CI: 0.002-0.033, P=0.028) was associated with an increase in PP in the study population. Besides, the waist-to-hip ratio had an effect-modification on the correlation of short-term exposure of PM 2.5 (interaction P=0.015), NO 2 (interaction P=0.008), and CO (interaction P=0.044) with CIMT, and the correlation between short-term exposure of PM 2.5 (interaction P=0.002), NO 2 (interaction P=0.010), CO (interaction P=0.029), PM 10 (interaction P<0.001) with PP. The significant association between CIMT, PP, and air pollution concentrations was more visible in people with lower waist-to-hip ratios. Conclusions:Short-term ambient air pollution exposure was associated with arterial stiffness indicators, and there was an effect modification of waist-to-hip ratio on these associations, and lower waist-to-hip ratios may enhance the association between air pollution exposure and indicators.

Background In recent years, radiation diagnosis and treatment technology has been increasingly applied and popularized in the medical field, and the status of radiation health protection has attracted widespread attention. Objective To understand the knowledge, attitude, and behavior of radiological health protection in radiation workers in Jiading District of Shanghai. Methods Convenience sampling method was used to select 441 radiation workers from 33 medical institutions in Jiading District, Shanghai to conduct a questionnaire survey from May to August 2023. Basic information and radiation protection associated knowledge, attitude, and behavior were collected from the study participants, and the scores of knowledge, attitude, and behavior were calculated. Factors affecting the behavior were evaluated by multiple linear regression. Results A total of 441 subjects were included in this study, with an age range of 22-71 years, 53.06% male and 46.94% female. In terms of knowledge, the correct response rate of the study subjects to the seven questions on the basics of radiation protection ranged from 44.22%-96.60%, with the lowest rate of 44.22% for the question on "radiation stochastic effect diseases". The subjects acquired knowledge about radiation hygiene mainly through vocational training (98.41%), and wanted to acquire knowledge mainly about the basics of nuclear and radiation (76.42%). In terms of attitude, the recognition level (strongly agree/agree) of the study subjects on the six attitude questions ranged from 73.47% to 96.37%, in which only 56.92% of the radiological staff at tertiary hospitals believed that the radiation dose they were exposed to at work would be hazardous to their health, and 73.85% believed that it was necessary to participate in training on knowledge of radiological protection, both lower than those in other levels of hospitals. In terms of behavior, the implementation rate (always/often) of the five behavioral questions by the study participants ranged from 75.28% to 91.84%, and there was a statistically significant difference in the total behavioral scores of the study participants by levels of hospitals (P=0.015). The results of multiple linear regression showed that gender, age, and radiation work permit associated with the behavioral scores of the study subjects. Conclusion In Jiading District, Shanghai, the coginitive rate of radiation workers' basic knowledge of theoretical protection still needs to be improved, and occupational training should be carried out in a targeted manner; the attitude of radiation workers varies by levels of hospitals, and the publicity and education of workers at tertiary hospitals in particular should be strengthened; and the supervision and management of male, senior, and non-certified radiation workers in hospitals of different levels should be enhanced.
